Description

Child safety seats

Technical Field

The utility model relates to the technical field of children's products, in particular to a child safety seat.

Background technique

Child safety seats are generally used when children ride in cars to improve the safety performance of children riding in cars. Child safety seats generally include a base and a seat shell arranged on the base. Some child safety seats also support support legs at the bottom of the base to prevent the child safety seat from tipping over and make the child safety seat more securely installed. The support legs can rotate relative to the base so that the support legs can be folded at the bottom of the base when not in use. However, in the prior art, when the support legs are not folded, they are all rotated backwards and folded at the bottom of the base. This way of folding the support legs means that if the child safety seat is forgotten to be opened before installation, the child safety seat must be disassembled after installation, the support legs must be opened, and then the child safety seat must be reinstalled. The same is true when the support legs are folded. The child safety seat must be disassembled first and then the support legs can be folded. This makes the use of child safety seats very inconvenient.

Detailed ways

The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

In the following description, the directions involved, such as "front", "rear", "left", "right", "up", "down", etc., are all based on the child safety seat being installed on the car seat, with the front direction of the car being "front", i.e., according to FIG. 2 , the right side direction in the figure is "front", the left side direction is "rear", the upper side direction is "up", the lower side direction is "down", and the directions perpendicular to the paper plane in the figure are "left" and "right". The definitions of the above directions are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention.

As shown in FIGS. 1 to 4 , the child safety seat comprises a base 1 , a seat shell 2 disposed on the base 1 , and a support leg 3 capable of being supported on the bottom of the base 1 .

The seat shell 2 is rotatably disposed on the base 1 via a rotating shaft extending in the up-down direction. The seat shell 2 can rotate relative to the base 1 around the rotating shaft, so that the child safety seat has at least a forward use state and a reverse use state.

When the child safety seat is in the forward use state, the child sits in the child safety seat with the child's face facing forward, as shown in Figures 1 and 2. When the child safety seat is in the reverse use state, the child sits in the child safety seat with the child's face facing backward, as shown in Figures 3 and 4. The seat shell 2 rotates relative to the base 1 around the rotation axis, so that the child safety seat can be switched between the forward use state and the reverse use state.

The child safety seat further includes a connecting member 4, which is slidably disposed in the base 1 in the front-rear direction, and one end of the support leg 3 is rotatably connected to the connecting member 4. In this way, the connecting member 4 can drive the support leg 3 to slide relative to the base 1, and the support leg 3 can rotate relative to the connecting member 4, so that the support leg 3 has a use state and a folded state.

When the support leg 3 is in use, the connector 4 slides to the front of the base 1, and the support leg 3 extends in the up-down direction and is supported on the bottom front of the base 1, as shown in Figures 1 to 9. When the support leg 3 is in the folded state, the support leg 3 extends in the front-to-back direction and is accommodated in the base 1, and the connector 4 slides to the rear of the base 1 and is located behind the support leg 3, as shown in Figures 10 to 12.

In this embodiment, a receiving cavity 11 is provided at the bottom of the base 1, and the connecting member 4 is slidably disposed in the receiving cavity 11 of the base 1 along the front-back direction, and the front of the receiving cavity 11 is open. In this way, the connecting member 4 can drive the supporting leg 3 to slide in the receiving cavity 11 of the base 1, so that the supporting leg 3 is accommodated in the receiving cavity 11 of the base 1, or extends from the receiving cavity 11.

When the support leg 3 is in the folded state, the support leg 3 is accommodated in the accommodating cavity 11, so that the appearance of the child safety seat is neat and beautiful. In addition, since the accommodating cavity 11 has a bottom, no additional stopper is required, and the support leg 3 will not fall out of the accommodating cavity 11, so that the structure of the child safety seat is simple.

When the supporting leg 3 is in the folded state and the connecting member 4 drives the supporting leg 3 to slide relative to the base 1 until the supporting leg 3 is completely out of the accommodating cavity 11 of the base 1, the supporting leg 3 can rotate relative to the connecting member 4, so that the supporting leg is converted to the use state.

The support leg 3 can be retracted. When the support leg 3 is in the folded state, the length of the support leg 3 is the shortest, as shown in Figures 10 to 12. When the support leg 3 is in use, the length of the support leg 3 can be adjusted according to the car in which the child safety seat is installed, so that the lower part of the support leg 3 can be supported on the car floor, as shown in Figures 5 to 9.

A guide structure is provided between the base 1 and the connecting member 4, so as to guide and limit the sliding of the connecting member 4. Specifically, as shown in FIG7 and FIG9, the guide structure includes a guide rod 42 provided on the connecting member 4 and a guide groove 111 provided on the base 1, and the guide groove 111 extends in the front-back direction. In this embodiment, the guide groove 111 is provided on the side wall of the accommodating cavity 11, and the guide rod 42 can be slidably provided in the guide groove 111. Through the cooperation between the guide groove 111 and the guide rod 42, the guiding and limiting effects on the sliding of the connecting member 4 are achieved.

The child safety seat further comprises a locking mechanism, which is used to lock the relative positions of the support leg 3 and the connecting member 4. The locking mechanism has a locked state and an unlocked state.

When the support leg 3 is in use, the locking mechanism is in a locked state, the relative positions of the support leg 3 and the connecting member 4 are fixed, the two cannot rotate relative to each other, and the connecting member 4 cannot slide relative to the base 1, so that the support leg 3 is stably supported on the bottom of the base 1, playing an effective supporting role to prevent the child safety seat from overturning, making the child safety seat more firmly installed, thereby improving the safety performance of the child safety seat when in use.

When the support leg 3 is in the folded state, the locking mechanism is in the unlocked state, so that the connecting member 4 slides relative to the base 1 until the support leg 3 is completely out of the accommodating cavity 11 of the base 1. The support leg 3 can be rotated relative to the connecting member 4 without the need to operate to unlock the locking mechanism, thereby facilitating the conversion of the support leg 3 from the folded state to the use state, thereby facilitating the use of the child safety seat.

The locking mechanism includes a locking member 5 slidably disposed on one of the supporting leg 3 and the connecting member 4 and a locking hole 41 disposed on the other and adapted to the locking member 5. When the locking mechanism is in a locked state, the locking member 5 is inserted into the locking hole 41, thereby locking the positions of the connecting member 4 and the supporting leg 3, as shown in FIGS. 18 to 20. When the locking mechanism is in an unlocked state, the locking member 5 is disengaged from the locking hole 41, and the supporting leg 3 can rotate relative to the connecting member 4, as shown in FIGS. 21 to 23.

When the supporting leg 3 is in the folded state, the position of the locking piece 5 is staggered from the position of the locking hole 41, and the two are spaced apart by a certain angle in the circumferential direction of the rotation of the supporting leg 3 relative to the connecting piece 4, so that the locking piece 5 cannot be inserted into the locking hole 41, thereby putting the locking mechanism in the unlocked state, as shown in Figures 24 to 26.

The child safety seat further includes an unlocking mechanism. When the locking mechanism is in a locked state, the unlocking mechanism can be unlocked, so that the support leg 3 can be folded. The unlocking mechanism includes an unlocking member 6. The unlocking member 6 can be slidably arranged on the parts of the support leg 3 and the connecting member 4 where the locking member 5 is arranged. The unlocking member 6 is fixedly connected to the locking member 5 or is arranged integrally.

In this embodiment, the locking mechanisms are respectively arranged on opposite sides of the support leg 3. The locking members 5 on both sides are slidably arranged on the support leg 3, and the locking holes 41 are respectively arranged on opposite sides of the connecting member 4. When the support leg 3 is in use, the locking members 5 on both sides are respectively inserted into the locking holes 41 on the corresponding side.

The child safety seat further comprises an elastic member 7, the elastic force of which is used to drive the locking mechanism to automatically reset from the unlocked state to the locked state. In this embodiment, the elastic member 7 is a spring, and the two ends of the spring are respectively disposed against the locking members 5 on both sides.

When the child safety seat is in forward or reverse use state and the support leg 3 needs to be used, the support leg 3 is in use state and the locking mechanism is in a locked state, thereby locking the position of the connecting piece 4 and the support leg 3. The length of the support leg 3 is adjusted according to the car where the child safety seat is installed, as shown in Figures 1 to 9.

When the support leg 3 is switched from the use state to the folded state, the support leg 3 is retracted to the shortest length, and the unlocking member 6 is operated to slide the locking member 5 relative to the support leg 3, so that the locking member 5 is disengaged from the locking hole 41, and the locking mechanism is unlocked. The support leg 3 is rotated forward relative to the connecting member 4 until the support leg 3 extends in the front-to-back direction, the positions of the locking member 5 and the locking hole 41 are staggered, and the locking mechanism remains unlocked. The connecting member 4 is slid backward relative to the base 1, driving the support leg 3 to slide synchronously in the same direction, and the support leg 3 gradually enters the accommodating cavity 11 of the base 1 until the support leg 3 is in the folded state, as shown in Figures 10 to 12.

When the support leg 3 is converted from the folded state to the use state, the front part of the support leg 3 is pulled, so that the support leg 3 drives the connecting member 4 to slide forward relative to the base 1 synchronously, and the support leg 3 gradually escapes from the accommodating cavity 11 of the base 1 until the support leg 3 is completely escaped from the accommodating cavity 11 of the base 1, as shown in Figures 13 to 17. The support leg 3 is rotated downward relative to the connecting member 4 until the support leg 3 extends in the up-down direction, at which time the locking member 5 corresponds to the position of the locking hole 41, and the locking member 5 automatically slides relative to the support leg 3 under the elastic force of the elastic member 7, thereby being inserted into the locking hole 41, so that the locking mechanism is in a locked state, and the support leg 3 is in a use state, as shown in Figures 1 to 9.

When the support leg 3 is switched from the use state to the folded state, the support leg 3 rotates forward relative to the base 1. When the support leg 3 is switched from the folded state to the use state, the support leg 3 first slides forward relative to the base 1 to the front of the base 1 and then rotates downward. This operation mode allows the support leg 3 to be freely switched between the use state and the folded state after the child safety seat is installed on the car seat, which makes the use of the child safety seat very convenient.

The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
