Description

Multilayer Floatable Omnidirectional Shock Absorbing Structure for Safety Helmet

technical field

The invention relates to a multi-layer floatable omnidirectional shock-absorbing structure of a safety helmet; in particular, it refers to a combination design of a multi-layer floatable structure using a buffer filling body combined with a main shell, a sub-shell and an elastic structure. The elastic structure is provided with a plurality of assembly parts, corresponding to the pivot parts of the main casing and the auxiliary casing, and the technology of composite molding an omnidirectional buffer helmet with an integral structure.

Background technique

The impact-resistant filling body formed by heating a plastic shell with a foam material is used, and the plastic shell is tightly wrapped and bonded to the foam filling body to complete a safety helmet or safety helmet structure, providing personnel to play ball games, The protective effect of riding sports and the like is already in the prior art. For example, U.S. Patent No. 4,466,138 "Safety Helmet with A Shell Injected from Thermoplastics And Method for The Manufacture of Said Helmet", and Taiwan No. 85101810 "Safety Helmet Manufacturing Method" provide typical examples.

The structure of this type of safety helmet is to use the external rubber shell to resist the impact of foreign objects, and at the same time, when the foam filler is impacted by external force, it provides buffering and dispersive transmission of the impact force to protect the user's head. Department effect.

The prior art has also disclosed a technology of attaching a layer of bubble pad between the rubber shell and the foam filler to assist in increasing the buffering effect. A problem related to the structural design and safety of the embodiment is that when the helmet is impacted by a general straight external force or hit (or pierced by a sharp object), the air bubbles are prone to bursting, reducing or losing its ability to provide. The effect of buffering to absorb the impact force; and the old method cannot effectively absorb the rotational torque (or shear force) that may be generated by the lateral external force impact and cause injury to the head of the person.

In detail, when a person's head strikes or is struck by another object, there are usually two types of mechanical forces that injure the head—linear acceleration force and angular acceleration force. Biomechanics in particular has determined that the aforementioned rotational torsion or angular acceleration forces are clearly capable of causing severe damage to the head of the type of brain trauma.

In order to improve the situation that the person's head is injured by the rotational torsion, the prior art discloses a kind of application between the rubber shell and the inner lining of the helmet, and a filament or damper is arranged to allow the helmet to be impacted When , it has the effect of absorbing the above-mentioned rotational torque; for example, US 2016/0278470 A1 (or WO 2016/154364) "PROTECTIVEHELMETS INCLUDING NON-LINEARLY DEFORMING ELEMENTS", US 2012/0198604 A1 "HELMETOMNIDIRECTIONAL MANAGEMENT SYSTEMS" patent cases, etc., provide specific examples.

As is known to those skilled in the art, in order to obtain effective omnidirectional rotational torsion absorption and structural strength, the prior art must make the above-mentioned filaments or damping components large in volume (or length) and full area (or Comprehensive) structural arrangement density (or quantity), but this will increase the volume and weight of the entire safety helmet, which will obviously affect the comfort and time of wearing, and also does not meet the requirements of the lightweight design of the helmet and the structural type that simplifies the production conditions. ; which is not what we expected.

That is to say, considering that the safety helmet obtains omnidirectional rotational torque absorption and has sufficient structural strength to resist (or load) the external positive impact force, it is necessary to reduce the volume and weight of the safety helmet as much as possible. A difficult subject.

Typically, these reference data show the design skills of existing safety helmets in terms of structure and manufacture; they also reflect the combined structure of the outer shell (or shell) and inner structure of these helmets, in practice There are some problems in the use case. If the redesign considers the internal combination structure and link relationship between the shell and the inner lining structure (or foam material layer), its structural strength can be improved, and its structure can be further designed to be different from the existing ones. The technology provides an ideal protection and buffering capacity, and at the same time has a comprehensive absorption effect such as rotational torque, which can change the transmission and dispersion pattern of external impact force and improve the shortcomings of the existing technology.

We found that we must consider improving the existing structure (for example, the bubble pad is easily broken and loses the cushioning and absorption effect), and the external impact forces of various types (forward or lateral) cannot be effectively dispersed through the internal structure (or foam material layer) It is transmitted to each area of the entire cap body, so that each part of the structure can load various types of impact forces in an all-round way; and, improving the existing technology to apply the filament or damping component structure to increase the volume of the entire helmet, Insufficient weight or structural strength (firmness), etc. In particular, the combined structure of the safety helmet has higher structural strength than the prior art in all directions or regions, so as to increase the load and support the effect of external impact or lateral impact pressure; and further, it conforms to the ease of manufacture And the structural form of the thin and light helmet design trend. However, the teaching or disclosure of these topics in the above reference data still cannot meet the needs of safety helmets at this stage.

And, an anchor is provided between at least a partial assembly part and an adjacent assembly part (or between the main casing and the sub casing). In addition, the filling body is formed to form an integral form to connect the auxiliary casing; under the condition of improving the overall structural strength, the functions of multiple floating omnidirectional buffering, rotational torque absorption and transmission of external impact force are achieved.

The above-mentioned "floating" refers to a situation in which a component can relatively move and/or rotate within the helmet in response to an external force. For example, when the elastic structure responds to an external force, it can relatively move and/or rotate between the main casing and the auxiliary casing, generate compression, elastic deformation and other movements.

According to the multi-layer floatable omnidirectional shock absorbing structure of the safety helmet of the present invention, the pivoting parts of the main shell and the auxiliary shell have protruding walls, defining the pivoting parts into a geometric outline (for example, a hexagonal outline), Adjacent each pivot part to form a honeycomb structure. And, the combined part of the elastic structure has a groove, which defines the combined part into a geometric outline (for example, a hexagonal outline), so that each combined part adjoins to form a honeycomb structure, correspondingly combining the above-mentioned pivoting parts.

According to the multi-layer floatable omnidirectional shock absorbing structure of the safety helmet of the present invention, an anchor is arranged between the main shell and the auxiliary shell. In practice, the anchors can be provided on the elastic structure. For example, the anchors are arranged on the combination parts, or at positions between partially adjacent combination parts. The anchor has an "I"-shaped structure, including a base and a first arm and a second arm formed on the base; two ends of the first arm and two ends of the second arm respectively have fingers, corresponding to the upper area of the combined elastic structure , the combined part of the lower region, to establish a mechanism or function to support the elastic structure.

Therefore, when the elastic structure and/or the anchor is deformed in response to (or loaded with) external impact force or rotational torsion force, buffering and absorbing the acting force, the anchor can assist the elastic structure body in the external impact force or rotation After the torque is removed, return to the original combined position.

Detailed ways

Please refer to FIGS. 1-3 , the multi-layer floatable and omnidirectional shock-absorbing structure of the safety helmet of the present invention, select an embodiment to provide a safety helmet for sports wear; the safety helmet can be American football, hockey helmet, engineering helmet, Mountaineering helmets, horse hats or half-face or full-face helmets for riding bicycles, motorcycles, skiing, racing...etc. It includes a combination of a main casing 10 , at least one elastic structure 20 , a secondary casing 50 and a filling body 30 formed of a buffer foam material.

References to upper, upper, lower, lower or bottom in the following description refer to the directions shown in the drawings. Also, the part facing the wearer is defined as the inner face or inner edge, and the part in the opposite or away from the wearer direction is defined as the outer surface or outer edge.

In the adopted embodiment, the main casing 10 and the secondary casing 50 can be made of plastic material, respectively, and have an inner surface 11, 51 facing the wearer's direction and an outer surface 12, 52 opposite to the wearer's direction, respectively. ; The inner surface 11 of the main casing and the outer surface 52 of the auxiliary casing are respectively contacted or connected to the elastic structure 20 . And, the outer surface 12 of the main casing is provided with a protective layer 60 ; the protective layer 60 can be made of glass fiber, carbon fiber material or similar materials to help increase the structural strength of the main casing 10 .

The figure shows that the inner surface 11 of the main casing and the outer surface 52 of the auxiliary casing are respectively formed with (elastic) pivot parts 13 and 53 . The main housing pivot part 13 and the auxiliary housing pivot part 53 have protruding walls 14 and 54 respectively, which define the cross section of the pivot part 13 (or 53 ) into a geometric outline (for example, a hexagonal outline), so that each The pivot portion 13 (or 53 ) adjoins to form a honeycomb structure.

In a feasible embodiment, one or more elastic structures 20 are arranged in the area between the main casing 10 and the auxiliary casing 50 . The elastic structure 20 is selected from a flexible or elastic material; for example, polystyrene (EPS), vinyl acetate copolymer (EVA), rubber . . . or the like. Therefore, the elastic modulus (or deformation) of the elastic structure 20 is greater than the elastic modulus (or deformation) of the filling body 30 , so as to increase the deformation of the elastic structure 20 and the shock absorption effect.

The figure depicts that the elastic structure 20 defines or has an upper area 21 and a lower area 22; . The upper region 21 and the lower region 22 of the elastic structure 20 are respectively provided with a plurality of combined parts 23; the combined part 23 of the elastic structure 20 is formed with a groove 24, which defines the combined part 23 (section) into a geometric outline (for example, six Angular profile), so that each combination part 23 adjoins to form a honeycomb structure, correspondingly combining or mortising the above-mentioned pivot parts 13 and 53 .

In a preferred embodiment, the elastic structure 20 is provided with a through hole 25 disposed on the assembly portion 23 ; the hole 25 can provide filling fluid to adjust or change the elastic modulus of the elastic structure 20 .

Please refer to FIGS. 3-4 , the inner surface 51 of the auxiliary casing is provided with the filler body 30 in combination. In the adopted embodiment, the filling body 30 is connected with the auxiliary casing 50 in cooperation with a mold or a forming module, and an integral composite type in which the main casing 10 wraps the elastic structure body 20 , the auxiliary casing 50 and the filling body 30 is formed. state (or assembly 100), and constitute a multi-layer floating composite structure.

The term "floating" refers to a situation in which the components can relatively move and/or rotate within the assembly 100 in response to an external force. For example, when the elastic structure body 20 responds to an external force, it can relatively move and/or rotate between the main casing 10 and the auxiliary casing 50 , generate compression, elastic deformation and other movements.

It can be understood that, if a gap is formed between the elastic structure 20 (or the combination part 23 ), the main casing 10 (or the pivot part 13 ) and the auxiliary casing 50 (or the pivot part 53 ), it will be possible to Add the above-mentioned "floating" situation or scope.

Figures 3 and 4 (or Figure 1 ) also show that the innermost layer of the assembly 100 or the lower region 31 of the foam filler 30 is combined with a cushion or secondary structure 40 for contacting and wrapping the user's head H (portion depicted by an imaginary line in the figure).

In a feasible embodiment, the secondary structure 40 is made of a flexible or elastic material (eg, rubber...or the like) to make a honeycomb-like structure. Part of the (foamed) material of the filling body 30 is combined or bonded to the secondary structure body 40 to form an integral form.

The figure (or FIG. 1 ) depicts the secondary structure 40 as comprising a plurality of skeletons 40A; the skeletons 40A define a plurality of (cross-section) well-shaped structural regions 45 having a geometric profile (eg, a hexagonal profile); and, the skeleton 40A is formed with protruding wings 46 toward the center of the well-shaped structure region 45 (or the peripheral region of the well-shaped structure region 45), so that the well-shaped structure region 45 defines the first region 41, the second region 42 and the A sub-area 43 between the first area 41 and the second area 42 .

Therefore, part of the material of the filling body 30 can fill the entire area of the first region 41 and the sub-region 43 to link the shape of the wing portion 46 .

Specifically, a part of the material of the filling body 30 enters each of the first regions 41 and/or the sub-regions 43 , so that the filling body 30 and the sub-structure body 40 are combined or bonded to form an integral structure. Also, a mechanism or role for the foam filler 30 to support the substructure 40 is established. The “bonding” refers to the structural type in which the material of the filling body 30 passes through or fills the linking sub-structure body 40 (or the first region 41 and the sub-region 43 ).

The figure shows a situation where part of the material of the filling body 30 enters the first region 41 and/or the sub-region 43, so the filling body located in the sub-structure body 40 (ie, the first region 41 and/or the sub-region 43) The density of 30 is lower than the density of the filler 30 in the outer region of the secondary structure 40; different foam structure densities constitute different force (or impact force) transmission, dispersion and buffer absorption effects.

In a feasible embodiment, the hardness of the main casing 10 (or the auxiliary casing 50 ) is greater than the hardness of the filling body 30 , and the hardness of the filling body 30 is greater than that of the elastic structure body 20 ; and the hardness of the elastic structure body 20 is greater than The hardness of the substructure 40 .

Please refer to FIG. 5 and FIG. 5A , when the external impact force (or normal force) impacts the assembly 100 , the main casing 10 and/or the auxiliary casing 50 and the filler 30 cooperate with the elastic structure 20 to generate a large impact force. The elastic deformation reduces the speed of the external impact force, and jointly loads the external impact force to produce a buffer absorption effect, and distribute the external impact force in all directions (or multiple directions) to the filler 30 and/or the entire assembly 100 . When the external impact force disappears, the structural characteristics of the elastic structure body 20 and/or the filler body 30 (or the sub-shell 50 ) can be used to return to the original combined position ( FIG. 4 ) as much as possible; for example, the 5th, 5A The situation depicted by the imaginary line K in the figure.

Referring to FIGS. 6 and 6A , when the external impact force (or shear force) impacts the assembly 100 , the main casing 10 and/or the auxiliary casing 50 and the filler 30 cooperate with the elastic structure 20 to generate a large The amount of elastic deformation reduces the rotational acceleration of the external impact force and the translational deformation pattern in response to the shear force, and jointly loads the external impact force to produce a buffer absorption effect, which disperses the external impact force in all directions (or multiple directions) to the filling The body 30 and/or the entire assembly 100 are used to absorb and reduce the acceleration and rotational torque generated by the external impact force. And, after the external impact force disappears, through the elastic deformation mechanism of the elastic structure 20 and/or the filling body 30, the function of returning to the initial combined position (FIG. 4); for example, the situation depicted by the imaginary line K in FIGS. 6 and 6A .

Compared with the rubber shell structure of the existing safety helmet, the main shell 10 and the auxiliary shell 50 are provided with the (elastic) pivot parts 13 and 53, which is helpful to increase the number of the main shell 10 and the auxiliary shell. The combined effect of the body 50 and the elastic structure body 20 is also beneficial to the main casing 10 and the auxiliary casing 50 to form a better structural strength to bear the external impact force.

It should be noted that the main casing 10 and the auxiliary casing 50 are provided with the pivoting parts 13 and 53 combined with the multi-layer floating structure of the elastic structure assembly part 23 (or the elastic structure 20 is movable and/or movable). The structure type located between the main casing 10 and the auxiliary casing 50 ), so that the elastic structure 20 responds to the above-mentioned rotational torsion force (or shearing force), and the main casing 10 and the auxiliary casing 50 face each other between the main casing 10 and the auxiliary casing 50 Movement, resulting in omnidirectional (or multi-directional) rotational displacement and translational displacement (or elastic deformation, translational deformation), and can minimize the situation that the rotational torsion force causes serious damage or trauma to the head H of the person.

Please refer to FIG. 7 , FIG. 8 and FIG. 9 , which show a modified embodiment; the structural cooperation situation of the elastic structure body 20 configured with the anchor 70 .

The figure depicts the position where the anchor 70 is disposed between the main housing 10 and the secondary housing 50 . In practice, the anchor 70 can be provided on the elastic structure 20 . For example, the anchors 70 are arranged on the combined parts 23, or at a position between some adjacent combined parts 23, so that the anchors 70 are located in the area between the inner surface 11 of the main casing and the outer surface 52 of the auxiliary casing ; Or make the anchor 70 set the hole 25 of the combined elastic structure 20 . Also, the combined structural form of the anchor 70 and the elastic structure 20 can form a similar anchoring effect, so as to obtain the effect of increasing the structural strength and the combined stability.

In the embodiment taken, the anchor 70 has an "I"-shaped structure including a base 75 and a first arm 71 and a second arm 72 formed on the base 75 . In detail, the upper part 76 of the base part 75 extends toward the two sides or the periphery (or perpendicular to the base part 75 ) to form the first arm 71 , and the lower part 77 of the base part 75 is provided with the second arm 72 ; A form extending in the direction perpendicular to the base 75). And, the first arm 71 and the second arm 72 have a joint surface 73 respectively, contacting or connecting the inner surface 11 (or the pivot part 13 ) of the main casing and the outer surface 52 (or the pivot part 53 ) of the auxiliary casing.

It can be understood that, the first arm joint surface 73 and the second arm joint surface 73 can be determined according to the curvature of the inner surface 11 (or the pivot part 13 ) of the main casing and the outer surface 52 (or the pivot part 53 ) of the auxiliary casing, respectively. The structure forming the arc surface enables the anchor 70 to form a stable contact or connection pattern with the inner surface 11 (or the pivot part 13 ) of the main casing and the outer surface 52 (or the pivot part 53 ) of the auxiliary casing, and allows When the anchor 70 responds to the external impact force, a smoother movement effect is produced between the main casing 10 and the auxiliary casing 50 .

In the embodiment taken, the second arm 72 is provided with a combination hole 78 to which the lower part 77 of the base 75 is fixed in combination. And, a cavity 74 is formed in the base portion 75 . Therefore, the wall thickness of the base 75 or the (cross-sectional) size of the cavity 74 can change the amount of deformation or elastic modulus of the anchor 70 .

7-9 also depict that the two ends of the first arm 71 and the two ends of the second arm 72 of the anchor 70 are respectively provided with a finger portion 79, corresponding to the combination portion 23 of the upper region 21 and the lower region 22 of the elastic structure. (or groove 24 ), establishes a mechanism or function to assist and support the elastic structure 20 .

Please refer to FIG. 10 and FIG. 10A , when the external impact force (or shear force) impacts the assembly 100 , the main casing 10 and/or the auxiliary casing 50 and the filler 30 cooperate with the anchor 70 and the elastic structure. 20 produces a large amount of elastic deformation and a translational deformation pattern in response to shearing force, jointly loads the external impact force to produce a buffer absorption effect, and distributes the external impact force in all directions (or multiple directions) to the filling body 30 and/or Or the entire assembly 100 to absorb and reduce acceleration and rotational torque from external impact forces.

And, the anchor 70 can further assist the elastic structure 20 to return to the initial combined position ( FIGS. 8 and 9 ) after the external impact force or rotational torque disappears; for example, the situation depicted by the imaginary line K in FIG. 10 .

That is to say, in the stress stage, the elastic structure 20 (and/or the anchor 70 ) is allowed to partially slide and/or move relative to the main housing 10 and the auxiliary housing 50, and the elastic structure 20 provides greater buffer tolerance and flexible fit, and allows the buffering and release of displacement/or rotational force between the interfaces of each component (combination), reducing the wearer's injury from external torsional impact .

It can be understood that, between the main casing 10 and the auxiliary casing 50 , multiple or multiple layers of elastic structures 20 may be disposed, or the assembly 100 may be configured with multiple or multiple layers of auxiliary structural bodies 40 .

Typically, the multi-layer floating omnidirectional shock-absorbing structure of this safety helmet includes the following advantages and considerations compared to the old law:

1. The combined structure of the main casing 10, the elastic structure 20, the auxiliary casing 50 and the filling body 30 has been redesigned to form a multi-layer floating structure; for example, make the inner surface 11 of the main casing . The outer surface 52 of the auxiliary casing has protruding walls 14 and 54 to form the pivot parts 13 and 53. At least one elastic structure 20 (and/or the anchor 70) is arranged between the main casing 10 and the auxiliary casing 50 ); the upper area 21 and the lower area 22 of the elastic structure 20 are provided with a plurality of combined parts 23 with grooves 24, combined with the pivot parts 13 and 53; the inner surface 51 of the auxiliary casing and the auxiliary structure 40 cooperate with the molding die, combined with filling and make the main shell 10, the elastic structure 20, the auxiliary shell 50 and the filling body 30 form a reinforced structure that covers and bonds with each other, which is obviously different from the structure of the conventional safety helmet.

2. The main shell 10 combines the structural organization of the elastic structure 20, the auxiliary shell 50 and the filling body 30, so that its structural strength can be significantly improved, and the structure can be further complied with the streamlined production and the thinning of the helmet. The design conditions provide an ideal protection and multi-directional buffering ability, and also change its transmission and dispersion pattern for external impact force, and improve the shortcomings of the conventional structure; for example, the bubble pad is easy to rupture and lose its buffering and absorbing effect. ; and, in the old method, the filament or damping component structure is used, in order to improve the structural strength and the shock absorption effect, the volume and weight of the entire helmet are increased.

3. In particular, the structural organization of the elastic structure body 20, the sub-shell 50, the filler body 30 and/or the anchor 70 enables them to have the effect of buffering absorption, reducing the force and speed of external impact, and further in their elastic recovery. In this stage, a buffer absorbs and reduces the force and speed of external impact.

Therefore, the present invention provides an effective multi-layer floatable omnidirectional shock absorbing structure of a safety helmet, whose spatial pattern is different from that of the prior art, and has incomparable advantages in the old law.

The above description is only illustrative rather than restrictive for the present invention, and those of ordinary skill in the art will understand that many modifications and changes can be made without departing from the spirit and scope defined by the following claims. or equivalent, but all fall within the protection scope of the present invention.
