[0036] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] It should be noted that in the description of the present invention, the terms "connection" and "installation" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or connected through an intermediate medium; it can be a mechanical connection or an electrical connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] The existing footrest device does not have an obstacle avoidance function. When the footrest body collides with the ground or an obstacle, the footrest body may break, which is not conducive to the driving of the electric vehicle.

[0040] Based on this, one embodiment of the present invention provides an obstacle avoidance footrest device, referring to Figure 1 The device comprises a support 1, a shelf foot body 2 rotatably mounted on the support 1, and an elastic member 3 connected between the support 1 and the shelf foot body 2;

[0041] The rotation axis of the shelf foot body 2 is parallel to the horizontal plane or is arranged at an acute angle to the horizontal plane; the elastic member 3 is used to apply elastic force to the shelf foot body 2 to rotate around the rotation axis of the shelf foot body 2 in a direction close to the ground.

[0042] In the present application, the footrest body 2 has an unfolded state and an obstacle avoidance state; under normal conditions, the footrest body 2 is in an unfolded state under the pull of the elastic member 3; when the footrest body 2 encounters an obstacle or touches the ground, the footrest body 2 can be pushed by the obstacle or the ground to rotate around the rotation axis of the footrest body 2 in a direction away from the ground, that is, the footrest body 2 can be switched from the unfolded state to the obstacle avoidance state, thereby alleviating the problem of collision between the footrest body 2 and the obstacle or the ground, avoiding the risk of the footrest body 2 breaking, and reducing the resistance of the obstacle or the ground to the footrest body 2, which is conducive to the smooth travel of the electric vehicle. After the footrest body 2 avoids the obstacle, the footrest body 2 is pulled back to the unfolded state by the elastic member 3, which is convenient for passengers to step on.

[0043] Reference Figure 2 The support 1 is provided with a plurality of mounting holes 12, through which the footrest device can be fixed on the electric vehicle. In this embodiment, the number of mounting holes 12 is three; the cross-sectional outer contour of the support 1 is rectangular, and the footrest body 2 and the three mounting holes 12 are respectively arranged at the four corners of the rectangular structure.

[0044] Reference Figure 2 and Figure 3 In this embodiment, the elastic member 3 is specifically a torsion spring, which includes a torsion spring body and two connecting rods respectively connected to both ends of the torsion spring body, and the two connecting rods are respectively in contact with the support 1 and the shelf foot body 2.

[0045] In other embodiments, the elastic member 3 can also be configured as a tension spring or a compression spring or other elastic member. By reasonably setting the connection relationship between the elastic member 3 and the support 1 and the shelf foot body 2, the elastic member 3 can apply an elastic force to the shelf foot body 2 to rotate around the rotation axis of the shelf foot body 2 in a direction close to the ground.

[0046] In this embodiment, a connecting groove 11 is provided on the support 1, and the footrest body 2 includes a treading portion 21 and a connecting portion 22, and the connecting portion 22 and the elastic member 3 are both arranged in the connecting groove 11;

[0047] The obstacle avoidance footrest device further comprises a rotating shaft 4, both ends of which are respectively inserted into the groove walls on both sides of the connecting groove 11, and the rotating shaft 4 passes through the connecting portion 22 and the torsion spring body.

[0048] In the above structure, the connecting portion 22 is clamped between the two side groove walls of the connecting groove 11, which can improve the connection strength between the support 1 and the shelf foot body 2; at the same time, the connecting groove 11 protects the elastic member 3, which can alleviate the problem of failure of the elastic member 3 and improve the service life of the elastic member 3.

[0049] On the basis of the above structure, the connecting part 22 includes two spaced connecting plates 222, and the elastic member 3 is arranged between the two connecting plates 222; the rotating shaft 4 passes through one side groove wall of the connecting groove 11, one of the connecting plates 222, the torsion spring body, the other connecting plate 222 and the other side groove wall of the connecting groove 11 in sequence; a shaft shoulder or a fastener (such as a nut, a retaining ring, a cotter pin and other fasteners) is provided at one end of the rotating shaft 4, and a fastener is provided at the other end of the rotating shaft 4, so as to limit the two ends of the rotating shaft 4 and install the rotating shaft 4 on the support 1.

[0050] In this embodiment, when the footrest body 2 is in the unfolded state, the bearing surface (i.e., the surface for stepping on) of the footrest body 2 is parallel to the horizontal plane. The above structure can facilitate passengers to step on and increase the comfort of passengers.

[0051] Continue to refer to Figure 2 and Figure 3 , at least one first limiting surface 111 is provided in the connecting groove 11, and at least one second limiting surface 221 is provided on the connecting portion 22, and the first limiting surface 111 corresponds to the second limiting surface 221 one by one;

[0052] A corresponding set of first limiting surfaces 111 and second limiting surfaces 221 can abut against each other.

[0053] Specifically, when the shelf foot body 2 is in the unfolded state, a corresponding set of first limit surfaces 111 and second limit surfaces 221 abut against each other; the first limit surfaces 111 and the second limit surfaces 221 can limit the maximum angle of rotation of the shelf foot body 2 relative to the support 1 in the direction close to the ground, so that passengers can step on the ground more smoothly.

[0054] In this embodiment, two first limiting surfaces 111 set at an angle are provided in the connecting groove 11, and correspondingly, two second limiting surfaces 221 are provided on the connecting portion 22; through the limitation of multiple groups of first limiting surfaces 111 and second limiting surfaces 221, the stability of the footrest body 2 during normal driving can be improved.

[0055] Reference Figure 4 The obstacle avoidance footrest device has a front end and a rear end that are arranged opposite to each other, and the front end of the obstacle avoidance footrest device faces the front of the electric vehicle;

[0056] The rotation axis of the footrest body 2 is set at an acute angle to the horizontal plane. Specifically, the rotation axis of the footrest body 2 is set to be inclined downward from the front end of the obstacle avoidance type footrest device to the rear end of the obstacle avoidance type footrest device.

[0057] Figure 4 and Figure 5 The dotted line in FIG. 1 is the rotation axis of the shelf body 2 (i.e., the axis of the rotating shaft 4). Figure 5 The dashed lines in the figure represent obstacles. Figure 5 When the electric vehicle is moving forward, when the footrest body 2 encounters an obstacle, since the rotation axis of the footrest body 2 is tilted downward from the front end of the obstacle avoidance type footrest device to the rear end of the obstacle avoidance type footrest device, the footrest body 2 will rotate at an obliquely upward angle under the push of the obstacle. Compared with the structure in which the rotation axis of the footrest body 2 is parallel to the horizontal plane, the technical solution provided in this embodiment is more conducive to avoiding obstacles and can further reduce the collision intensity between the footrest body 2 and the obstacle.

[0058] Based on the above structure, refer to Figure 5 The angle a between the rotation axis of the footrest body 2 and the horizontal plane is in the range of 15° to 45°. If the angle a is greater than 45°, the obstacle avoidance effect of the footrest body 2 when touching the ground will be reduced.

[0059] Furthermore, a curved surface 212 is provided on one side of the footrest body 2 near the front end of the obstacle avoidance footrest device. When the footrest body 2 encounters an obstacle during the forward movement of the vehicle, the provision of the curved surface 212 is conducive to the footrest body 2 to pass over the obstacle. In this embodiment, the curved surfaces 212 are provided on both opposite sides of the footrest body 2.

[0060] Reference Figure 6 The obstacle avoidance footrest device further comprises an elastic pad 5, which is mounted on the bearing surface of the footrest body 2. The elastic pad 5 can be made of elastic materials such as rubber, and the elastic pad 5 can increase the friction between the footrest body 2 and the foot contact surface, thereby improving the comfort of the passengers.

[0061] In this embodiment, a receiving groove 213 is disposed on the bearing surface of the footrest body 2 , and the elastic pad 5 is disposed in the receiving groove 213 .

[0062] Reference Figure 6 and Figure 7 , at least one clamping column 51 is provided on the elastic pad 5, and at least one clamping hole 211 is provided on the foot body 2. The clamping column 51 corresponds to the clamping hole 211 one by one, and a corresponding group of clamping columns 51 and the clamping hole 211 are clamped and matched. Specifically, a protruding structure is provided at one end of the clamping column 51 away from the bearing surface of the elastic pad 5, and the clamping hole 211 passes through the bottom of the groove 213; when installing, the elastic pad 5 is aligned with the groove 213 and pressed into the groove 213. In this process, a corresponding group of clamping columns 51 are inserted into the clamping hole 211, and the elastic pad 5 is fixed to the foot body 2 through the protruding structure at the end of the clamping column 51.

[0063] In the above structure, since the elastic pad 5 adopts a press-fit assembly structure, the elastic pad 5 is not easy to fall off, has strong practicality, and is easy to replace.

[0064] Another aspect of the present invention provides an electric vehicle, which includes the obstacle avoidance footrest device described in any one of the above embodiments. Therefore, the electric vehicle at least has the technical effects of the above obstacle avoidance footrest device, which will not be repeated here.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
