The present invention provides a balance car 10 , as shown in FIG. 1 , including a casing 100 and two wheels 120 . Two wheels 120 are provided at both ends of the casing 100, respectively. The shell 100 is the main part of the balance bike 10 , and is also the part of the balance bike 10 that accounts for the largest volume of the balance bike 10 and can be directly seen and frequently touched by the user. The first casing 141 and the second casing 142 are both provided with a stepping portion 130, and the user stands on the stepping portion 130 when using. Housing 100 has fenders 110 extending over wheels 120 . The fenders 110 are used to prevent the water or mud stains carried by the wheels 120 from splashing on the user during the running process of the wheels 120 .

For the housing 100, the housing 100 may be continuous and uninterrupted in the length direction, that is, the upper and lower housings of the housing 100 are continuous and not divided into left and right parts. The housing 100 may be discontinuous and interrupted in the length direction, as shown in FIG. 1 , that is, the housing 100 includes two left and right parts (ie, the first shell 141 and the second shell 142 ), and the middle structure is also It's called a twisting car. When the casing 100 is divided into left and right parts, the left and right parts of the casing 100 are rotatably connected by a connecting shaft (not shown in the figure); , it can be a segmented structure, that is, it includes a first shaft body (not shown in the figure), a second shaft body (not shown in the figure) and a connecting segment (not shown in the figure), and one end of the connecting segment is rotatably connected to the first shaft body (not shown in the figure). One axle body, the other end is fixedly connected to the second axle body, and the two wheels 120 are respectively fixed to the first axle body and the second axle body.

Further, the first casing 141 can be divided into a first upper casing (not shown) and a first lower casing (not shown). The first upper case and the first lower case are detachably connected. When the first upper case is connected with the first lower case, a first cavity is formed. The second casing 142 includes a second upper casing (not shown) and a second lower casing (not shown). The second upper case is detachably connected with the second lower case, and when the second upper case is connected with the second lower case, a second cavity is formed. The first shaft body is located in the first cavity, and the second shaft body is located in the second cavity. The first casing 141 and the second casing 142 are divided into upper and lower parts, which can effectively reduce the installation difficulty of the connecting shaft and improve the production efficiency.

Further, the first shaft body and/or the second shaft body may be hollow shafts. The use of the hollow shaft can effectively reduce the overall weight of the balance car 10 and is convenient for the user to pick, place and carry.

Furthermore, the first shaft body and/or the second shaft body may be round shafts. The round shaft is more convenient to process, and is more stable and less deformed than shafts of other shapes.

Specifically, in this embodiment, both the first shaft body and the second shaft body are hollow circular shafts.

The stepping portion 130 is an area for the user to step on directly. The treading portion 130 may be a part of the casing 100 , that is, the treading portion 130 and the casing 100 are integrally provided, and a foot pad is not provided at this time. The tread portion 130 may be the same hard plastic as the portion of the housing 100 except for the tread portion 130 .

In addition, the treading part 130 may not be a part of the casing 100 , that is, the treading part 130 and the casing 100 are provided separately, and the treading part 130 may be a foot pad, as shown in FIGS. 1-3 .

Further, the balance car 10 further includes a controller (not shown in the figure), a sensor (not shown in the figure), an acceleration sensor (not shown in the figure), and a gyroscope (not shown in the figure) provided inside the casing 100 . The controller is electrically connected to the in-wheel motor of the wheel 120 . The controller is used to control the start and stop of the in-wheel motor. The sensor is used to sense whether the user has stepped on the balance bike 10 . After the sensor senses that the user is standing on the balance car 10 , the sensor transmits a trigger signal to the controller to control the two wheels 120 to start working. By stepping on the two pedaling parts 130, the user transmits different control signals to the controller to control the rotation and stop of the wheels 120, thereby controlling the balance vehicle 10 to move forward, backward or decelerate.

The two stepping parts 130 on the housing 100 play a role of guiding the stepping position to the user. Therefore, the positional relationship between the two stepping parts 130 is very important. Under the guidance of the pedaling part 130, when the user gets on the balance bike 10, if the distance between the feet is suitable, the user will be in a natural standing posture, which is convenient for the user to step on and stand. In addition, in the face of various and complex road conditions, the user can quickly adjust the motion state of the self-balancing vehicle 10 to further improve the safety performance of the self-balancing vehicle 10 .

If the distance between the feet is too small, the user needs to connect the feet or bend the legs into an "O" shape to use the balance bike 10 normally. When using the feet together, when stepping on the two pedals 130, the knees and the feet are likely to rub against each other, and it is easy to have obvious discomfort, which is not conducive to controlling the steering of the balance bike 10; The knees rub against each other and the legs are bent into an "O" shape, which will lead to an unnatural standing posture, which is not conducive to the user maintaining a normal standing posture. In addition, in the face of various and complicated road conditions, it is easy to have obvious discomfort when using this to exert force through the feet, which is not conducive to controlling the balance vehicle 10 to turn. In addition, when faced with various and complex road conditions, it is difficult for the user to quickly adjust the motion state of the self-balancing vehicle 10 .

If the distance between the feet is too large, the user needs to spread the feet apart to use the balance bike 10. Such an unnatural standing posture brings discomfort to the user's body and mind, and is not conducive to the user maintaining a normal standing posture. In addition, when faced with various and complex road conditions, it is difficult for the user to quickly adjust the motion state of the self-balancing vehicle 10 . Further, at this time, it is necessary to increase the length of the balance car 10 to provide the user with a corresponding stepping position. When the place where the balance car 10 needs to pass is narrow, it is easy for the balance car 10 to collide with the obstacles at both ends. It brings danger and easily damages the balance vehicle 10 .

Therefore, as shown in FIGS. 1 , 2 and 3 , the distance between the centers of the two wheels 120 is S1 , and the distance between the centers of the two tread portions 130 is S2 . The value of S2/S1 is T. The value range of T is 0.55-0.75. At this time, the user's feet on the balance bike 10 have a suitable distance and are in a natural standing posture, and the pedaling and standing postures are natural. In addition, in the face of various and complex road conditions, the user can quickly adjust the motion state of the self-balancing vehicle 10 to further ensure the safety of the user. It can be understood that when the value of T is 0.55 or 0.75, the distance between the feet of the user boarding the balance car 10 is also suitable.

It should be noted that the center of the wheel 120 is the position of the intersection of the rotation axis of the wheel 120 and the tangent plane located at half the thickness of the wheel 120 . The center-to-center distance S1 of the two wheels 120 is the length of a straight line segment determined by the centers of the two wheels 120 .

It should also be noted that, the center distance S2 of the two tread portions 130 may be calculated in the following manner. First, the following definitions are clearly defined:

Let the longitudinal direction of the housing 100 be the X-axis direction, let the direction parallel to the plane where the pedaling portion 130 is located and perpendicular to the X-axis be the Y-axis direction, let the plane where the pedaling portion 130 is located, and perpendicular to the X-axis (or to the Y-axis). parallel) is the longitudinal section.

For the tread portion 130 on the left half of the housing 100: let the line segment on the tread portion 130 intersecting the longitudinal section be the first length L1; let the longest line segment intersecting the longitudinal section on the tread portion 130 be the first maximum length L2 . In addition, the end of the left half of the casing 100 close to the corresponding wheel 120 is the first starting point; the end of the left half of the casing 100 away from the corresponding wheel 120 is the first end point.

For the tread portion 130 on the right half of the housing 100: let the line segment on the tread portion 130 intersecting the longitudinal section be the second length M1; let the longest line segment intersecting the longitudinal section on the tread portion 130 be the second maximum length M2 . In addition, take the end of the right half of the casing 100 close to the corresponding wheel 120 as the second starting point; the end of the right half of the casing 100 away from the corresponding wheel 120 is the second ending point.

Then, according to the above definition, the following steps are used to calculate the center distance S2 of the two pedaling parts 130:

S100. The longitudinal section starts from the first starting point and moves toward the first end point. During the movement, when the ratio α1 of the first length L1 to the second maximum length L2 falls on the interval [0.75-1] for the first time, the longitudinal section is the first delimiting plane P1;

S200. The longitudinal section starts from the first end point and moves toward the first start point. During the movement, when the ratio β1 of the first length L1 to the second maximum length L2 falls on the interval [0.75-1] for the first time, the longitudinal section is the second delimiting surface P2;

S300, define the position of the midpoint between the first demarcation surface P1 and the second delineation surface P2 as A1;

S400. The longitudinal section starts from the second starting point and moves toward the second end point. During the movement, when the ratio α2 of the second length M1 to the second maximum length M2 falls on the interval [0.75-1] for the first time, the longitudinal section is The third delimiting plane P3;

S500, the longitudinal section starts from the second end point and moves toward the second start point. During the movement, when the ratio β2 of the second length M1 to the second maximum length M2 falls on the interval [0.75-1] for the first time, the longitudinal section is the fourth demarcation plane P4;

S600, define the position of the midpoint between the third demarcation surface P3 and the fourth delineation surface P4 as A2;

The distance between A1 and A2 is the center distance S2 of the two tread portions 130 .

It should be noted that, when the distance between A1 and A2 is inconvenient to directly calculate, (that is, when the position of A1 and A2 is inconvenient to directly determine), the following method can be adopted to calculate the center distance S2 of the two pedaling parts 130:

S101. The longitudinal section starts from the first starting point and moves toward the first end point. During the movement, when the ratio α1 of the first length L1 and the second maximum length L2 falls on the interval [0.75-1] for the first time, the longitudinal section is the first delimiting plane P1;

S201. The longitudinal section starts from the first end point and moves toward the first start point. During the movement, when the ratio β1 of the first length L1 to the second maximum length L2 falls on the interval [0.75-1] for the first time, the longitudinal section is the second delimiting surface P2;

S301. The longitudinal section starts from the second starting point and moves toward the second end point. During the movement, when the ratio α2 of the second length M1 to the second maximum length M2 falls on the interval [0.75-1] for the first time, the longitudinal section is The third delimiting plane P3;

S401. The longitudinal section starts from the second end point and moves toward the second start point. During the movement, when the ratio β2 of the second length M1 to the second maximum length M2 falls on the interval [0.75-1] for the first time, the longitudinal section is the fourth demarcation plane P4;

S501, the distance between P1 on the left half of the housing 100 and P3 on the right half of the housing 100 is B1, and the distance between P2 on the left half of the housing 100 and P4 on the right half of the housing 100 is B2 , S2=(B1+B2)/2.

It can be understood that the interval [0.75-1] includes two boundary values of 0.75 and 1, that is, when the ratio α1 of the first length L1 to the second maximum length L2 is 0.75 or 1 for the first time, the longitudinal section is the first delineation face P1; when the ratio β1 of the first length L1 to the second maximum length L2 is 0.75 or 1 for the first time, the longitudinal section is the second delimiting face P2; when the ratio α2 of the second length M1 to the second maximum length M2 is the first time When it is 0.75 or 1, the longitudinal section is the third delimiting plane P3; when the ratio β2 of the second length M1 to the second maximum length M2 is 0.75 or 1 for the first time, the longitudinal interface is the fourth delimiting plane P4.

Specifically, please refer to FIG. 1 , FIG. 2 and FIG. 3 , in this embodiment, L1 at the first starting point of the left half of the housing 100 is 12CM; the first maximum length L2 is 14.8CM; it can be seen that α1 is 0.81, falls within the interval [0.75-1]; therefore, the first delimiting plane P1 of the left half of the housing 100 is at this first starting point. The left half of the housing 100 moves from the first end point to the first start point and records the length of L1 at any time, and further determines whether the ratio β1 of L1 and L2 falls within the interval [0.75-1]. As shown in FIG. 3, the first length L1 at the dotted line P2 is 11.1CM, and the ratio β1 of L1 and L2 is 0.75, which is the first time it falls within the interval [0.75-1]. Therefore, here is the second delimiting surface P2 .

Similarly, in this embodiment, M1 at the second starting point of the second housing 142 is also 12CM; the second maximum length M2 is also 14.8CM; it can be seen that β1 is 0.81, which falls within the interval [0.75-1]; Therefore, the first demarcation surface P3 of the second casing 141 is the second starting point. The second housing 142 moves from the second end point to the second start point and records the length of M1 at any time, and further determines whether the ratio β2 of L1 and L2 falls within the interval [0.75-1]. As shown in FIG. 3, the second length M1 at the dotted line P4 is 11.1CM, and the ratio β2 of M1 and M2 is 0.75, which is the first time it falls within the interval [0.75-1], therefore, here is the fourth demarcation surface P4 .

It should be noted that, in the actual calculation process, the position of A2 needs to be determined after the positions of P1, P2, P3, and P4 are determined, and then the midpoint of P1 and P2, and the midpoint of P3 and P4 are calculated. The location of the "midpoint" of this process is more difficult to determine and calculate. But directly measuring the distance B1 between P1 and P3, and directly measuring the distance B2 between P2 and P4, and then using a simple formula to calculate S2, such a measurement process and method is more direct and convenient.

Specifically, please refer to FIG. 3 , in this embodiment, the distance B1 between P1 and P3 is 47CM, and the distance B2 between P2 and P4 is 25.6CM.

Therefore, the center-to-center distance between the two tread portions 130 is S2=(B1+B2)/2=36.6CM.

As shown in FIG. 2 , the pedaling portion 130 is provided with a pedaling position 131, and the pedaling position 131 is an area that is convenient for placing the feet. If it is too thin, it is easy for the user to feel that only the middle of the sole has stable support, while the two ends are suspended, and the use experience is poor. Therefore, the length of the pedaling position 131 should not be shorter than 50% of the average foot length of the user. As shown in FIG. 2 , most areas of the pedaling portion 130 can be regarded as the pedaling position 131 , that is, although the user can stand on the pedaling portion 130 to control the balance bike 10 , only when the user is standing on the pedaling portion 130 The best standing experience and control feel can be obtained only when the pedaling position 131 is on. The longitudinal direction of the stepping position 131 (any direction indicated by arrow C in FIG. 3 ) is perpendicular to the longitudinal direction of the housing 100 (any direction indicated by arrow D in FIG. 3 ). Therefore, when the user stands on the pedaling position 131, the length direction of the soles of his feet is the same as the longitudinal direction of the pedaling position 131, and is also consistent with the forward (or backward) direction of the wheel 120. At the same time, the forward direction of the user's eyes is also the same as the wheel 120 is moving forward. The direction is consistent, which is beneficial for the user to observe the surrounding environment, and it is convenient for the user to adjust the standing posture at any time according to their own conditions and changes in the environment, so as to control the forward, backward or stop of the balance car 10 .

It can be understood that the pedaling position 131 may be a part of the area on the pedaling portion 130 . At this time, although the user can stand on the pedaling portion 130 to control the balance bike 10 , only when the user stands on the pedaling position 131 can the best standing experience and control feel be obtained.

It is also understandable that structures that increase the coefficient of friction between the user and the pedaling portion 130, such as anti-slip patterns, anti-slip sheets, etc., may be provided on the pedaling position 131 to prevent the user from slipping from the pedaling portion 130 when adjusting the standing posture.

Further, the length of the middle of the stepping position 131 is not less than the length of both ends of the stepping position 131 .

As shown in FIG. 1 and FIG. 2 , as long as the stepping position 131 can be used by the user to stand, it can be a continuous area composed of a complete structure, and the graphics presented by the overall outer contour of the area can be regular graphics, or Can be irregular shapes. Of course, the stepping position 131 may also be formed by an area occupied by a plurality of smaller and discretely distributed sub-stepping parts (not shown), and the overall outer contour of the area, that is, the outer contour of the stepping position 131, may be a regular figure or irregular shapes.

It can be understood that, when the stepping position 131 is a continuous structure and has a regular shape, the stepping position 131 may have a circular shape, a square shape, a diamond shape, or the like. When the pedal position 131 is a continuous structure and the shape is irregular, the length of the middle position of the pedal position 131 should be greater than the length of the two ends of the pedal position 131 that are consistent with the length direction of the connecting shaft. Therefore, the pedal position 131 can provide users with better Pedal feel and control.

In addition, when the stepping position 131 is a discrete structure: the stepping portion 130 includes at least two sub-stepping portions, and the at least two sub-stepping portions are combined to form a stepping position 131 for the user to stand. The plurality of sub-stamping parts may be distributed on the treading part 130 in a scattered shape, or two, three or more aggregate blocks may be formed on the treading part 130 for the user to tread on.

The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity, all possible combinations of the technical features in the above-described embodiments are not described. However, as long as there is no contradiction between the combinations of these technical features, All should be regarded as the scope described in this specification.

The above-mentioned embodiments only represent several embodiments of the present invention, and the descriptions thereof are specific and detailed, but should not be construed as a limitation on the scope of the invention patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can also be made, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
