[0055] In this embodiment, when testing the electric tricycle, the electric tricycle is first lifted with the assistance of a gantry crane or other device so that the front wheel of the electric tricycle is located between the first support cross bar 33 and the second support cross bar 34, and the body of the electric tricycle is driven to descend so that the two rear wheels of the electric tricycle are completely in contact with the plate surface of the conveying chain plate 21 (i.e., the plate surface between the end of the conveying chain plate 21 close to the first support column 31 and the first square hole 211 or the plate surface between the end of the conveying chain plate 21 close to the second support column 32 and the second square hole 212), and the front wheel of the electric tricycle is fastened by the connecting belt 35. After that, the forward and reverse chain plate conveyor 2 works, the conveying chain plate 21 starts to move, and the electric vehicle wheels are driven to rotate by friction (the conveying chain plate 21, the first arc-shaped side plate 42, the first arc-shaped bottom plate 41, the second arc-shaped bottom plate 51 and the first arc-shaped bottom plate 52). The surface roughness of the two arc-shaped side plates 52 can be appropriately set to be larger), and the rotation direction of the electric tricycle wheel is consistent with the direction of the electric vehicle when it is moving forward, which is convenient for simulating the rear wheel of the electric tricycle driving on a flat road; and when the two rear wheels of the electric tricycle completely correspond to the position of the first disturbance plate 4, when the rear wheel of the electric tricycle moves from being located on the surface of the conveying chain plate 21 to being located in the first arc-shaped bottom plate 41, the rear wheel of the electric tricycle is lowered, and through the guiding effect of the first arc-shaped bottom plate 41 and the first arc-shaped side plate 42, the rear wheel of the electric tricycle can be re-located on the surface of the conveying chain plate 21, thereby realizing the ascent of the rear wheel of the electric tricycle. Since the first disturbance plate 4 is provided on each conveying chain plate 21, it is convenient to cause the vibration of the electric tricycle, thereby simulating the situation where the rear wheel of the electric tricycle causes the electric tricycle to vibrate when driving on a bumpy road section.

[0056] When the two rear wheels of the electric tricycle completely correspond to the position of the second disturbance plate 5, since the arc length of the second arc-shaped bottom plate 51 is greater than the arc length of the first arc-shaped bottom plate 41, the inner annular surface diameter of the second arc-shaped bottom plate 51 is greater than the inner annular surface diameter of the first arc-shaped bottom plate 41, and the bottom end of the first arc-shaped bottom plate 41 on each conveying chain plate 21 located above and in a horizontal state is higher than the bottom end of the second arc-shaped bottom plate 51 on the conveying chain plate 21. Therefore, compared with the first disturbance plate 4, the second arc-shaped second disturbance plate 5 can make the electric tricycle produce a more violent vibration effect.

[0057] When one of the rear wheels of the electric tricycle is always in contact with the surface of the conveying chain plate 21 between the first support column 31 and the first square hole 211, and the other rear wheel of the electric tricycle corresponds to the position of the first disturbance plate 4, the vibration simulation of the two rear wheels of the electric tricycle in different road conditions can also be realized; similarly, when the two rear wheels of the electric tricycle correspond to the first disturbance plate 4 and the second disturbance plate 5 respectively, the vibration simulation of the two rear wheels of the electric tricycle in different road conditions can also be realized; in addition, when one of the rear wheels of the electric tricycle is always in contact with the surface of the conveying chain plate 21 between the second support column 32 and the second square hole 212, and the other rear wheel of the electric tricycle corresponds to the position of the second disturbance plate 5, the vibration simulation of the electric tricycle when the two rear wheels of the electric tricycle are in different road conditions can also be realized.

[0058] In addition, when the conveying chain plate 21 starts to move, the electric vehicle wheel is driven to rotate by relying on the friction force, and the rotation direction of the electric tricycle wheel is made the same as the direction when the electric vehicle moves backward. By repeating the above operations, it is possible to simulate various different vibration conditions of the electric tricycle caused by the rear wheel moving backward of the electric tricycle, thereby providing a diverse testing environment.

[0059] Embodiment 2

[0060] See also Figure 1 , Figure 8 This embodiment is based on the first embodiment, and two connecting straps 35 are also provided on the second supporting cross bar 34. The two connecting straps 35 are close to the end of the second supporting cross bar 34. The two connecting straps 35 on the second supporting cross bar 34 are also used to tighten the front wheels of the electric tricycle, which helps to reduce the risk of the front wheels of the electric tricycle falling off during the test.

[0061] Embodiment 3

[0062] See also Figure 1-Figure 9 This embodiment is based on the second embodiment, and further includes a guide assembly 6, which includes a first bracket 63 and a second bracket 64. The first bracket 63 and the second bracket 64 are both arranged on the base 1. An inclined plate 61 is fixedly arranged on the first bracket 63, and the bottom end of the inclined plate 61 contacts the top surface of the base 1; a transverse plate 62 is fixedly arranged on the second bracket 64, and one end of the transverse plate 62 is connected to the top end of the inclined plate 61, and the other end of the transverse plate 62 is close to the end of the forward and reverse chain conveyor 2.

[0063] By providing the inclined plate 61, it is convenient for the electric tricycle to move from the ground to the horizontal plate 62, which helps the two rear wheels of the electric tricycle to align with the first disruptor plate 4 or the second disruptor plate 5, etc., thereby helping to reduce the moving distance of the electric tricycle carried by devices such as the gantry hanger, thereby reducing safety hazards to a certain extent.

[0064] When the test is completed, all the connecting belts 35 are released, and the electric tricycle is placed on the horizontal plate 62 again with the assistance of a gantry hanger or the like. At this time, the inclined plate 61 facilitates the electric tricycle to move to the ground.
