[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] Example 1: Please refer to Figures 1 to 4 In this embodiment, an electric vehicle front fork impact testing device includes a debugging component 2 arranged on the upper surface of the testing device body 1, which is used to connect and adjust the impact angle of the front fork.

The fixing frame 21 is arranged on the upper surface of the test equipment body 1, and the adjusting shaft 22 is rotatably arranged inside the fixing frame 21. A front fork connecting seat 23 is provided on the outside of the adjusting shaft 22 for connecting the front fork components. A connecting frame 24 is fixed to the left side of the fixing frame 21, and the left end of the adjusting shaft 22 is rotatably connected to the left inner wall of the connecting frame 24. A return spring 25 is provided on the outside of the adjusting shaft 22 and located inside the connecting frame 24. A push plate 26 is provided at the right end of the return spring 25, and a limiting sleeve 27 is provided on the right side of the push plate 26. A docking sleeve 28 is fixed on the outside of the adjusting shaft 22 and on the right side of the limiting sleeve 27 to cooperate with the limiting sleeve 27 to fix the position of the adjusting shaft 22.
[0024] The debugging assembly 2 also includes a separation frame 29 arranged on the upper surface of the push plate 26, which is used to push the limiting sleeve 27 and the docking sleeve 28 to separate. The front fork component of the electric vehicle is installed on the front fork connecting seat 23, and the separation frame 29 is pushed to move it. The movement of the separation frame 29 drives the push plate 26 to move, so that the limiting sleeve 27 and the docking sleeve 28 are separated, and the reset spring 25 is compressed. The right side of the separation frame 29 is provided with a rotating shaft 210 for driving the adjustment shaft 22 to rotate and adjust the test angle. As the separation frame 29 moves, the rotating shaft 210 and the plug plate 215 are respectively inserted into the socket 214 and the slot in the adjustment shaft 22, thereby completing the unlocking of the adjustment shaft 22 and connecting the rotating shaft 210 to the adjustment shaft 22.
[0025] In this embodiment, side plates 211 are provided on the outside of the adjustment shaft 22 and on the left and right sides of the front fork connecting seat 23, and support springs 212 are fixed on the opposite sides of the two side plates 211, and support frames 213 are provided on the opposite sides of the two support springs 212 to support the sides of the front fork components. The side plates 211 and the support springs 212 are adjusted to ensure that the sides of the front fork components are properly supported. According to the test requirements, the parameters of the impact test mechanism are set, the impact test mechanism is started, and a predetermined impact force is applied to the front fork components.
[0026] In this embodiment, a plurality of tooth grooves are provided on the opposite side of the limiting sleeve 27 and the docking sleeve 28 for the limiting sleeve 27 and the docking sleeve 28 to engage with each other, and a socket 214 is provided at the right end of the adjusting shaft 22 for inserting the rotating shaft 210, and slots are provided on the upper and lower inner walls of the socket 214, and an insert plate 215 corresponding to the positions of the two slots is fixed on the outer side of the rotating shaft 210 to drive the adjusting shaft 22 to rotate and adjust.
[0027] In this embodiment, sliding openings are provided on the left and right sides of the fixing frame 21, and the separation frame 29 is slidably arranged inside the sliding hole. A handwheel 216 is provided at the right end of the rotating shaft 210 to drive the rotating shaft 210 to rotate. A guide rail is provided on the inner bottom wall of the connecting frame 24, and a sliding groove is provided on the lower surface of the push plate 26, and the push plate 26 is slidably arranged on the outside of the guide rail through the sliding groove to keep the push plate 26 moving smoothly. By turning the handwheel 216, the rotating shaft 210 and the adjusting shaft 22 are driven to rotate together, and the rotation of the adjusting shaft 22 drives the front fork connecting seat 23 to rotate for angle adjustment.
[0028] It should be noted that after adjusting to the desired angle, the separation frame 29 is released, and the reset spring 25 generates a rebound force to push the push plate 26 to reset. After the push plate 26 is reset, the limiting sleeve 27 and the docking sleeve 28 engage to lock the position of the adjustment shaft 22.
[0029] The working principle of the above embodiment is:
[0030] Install the front fork component of the electric vehicle on the front fork connecting seat 23, push the separation frame 29 to move it, and the movement of the separation frame 29 drives the push plate 26 to move, so that the limiting sleeve 27 and the docking sleeve 28 are separated, and the reset spring 25 is compressed. As the separation frame 29 moves, the rotating shaft 210 and the plug plate 215 are respectively inserted into the socket 214 and the slot in the adjusting shaft 22, completing the unlocking of the adjusting shaft 22 and connecting the rotating shaft 210 with the adjusting shaft 22. By turning the hand wheel 216, the rotating shaft 210 and the adjusting shaft 22 are driven together. Rotate, the rotation of the adjusting shaft 22 drives the front fork connecting seat 23 to rotate to adjust the angle. After adjusting to the required angle, release the separation frame 29, and the reset spring 25 generates a rebound force to push the push plate 26 to reset. After the push plate 26 is reset, the limiting sleeve 27 and the docking sleeve 28 engage to lock the position of the adjusting shaft 22. Adjust the side plate 211 and the support spring 212 to ensure that the side of the front fork component is properly supported. According to the test requirements, set the parameters of the impact test mechanism, start the impact test mechanism, and apply a predetermined impact force to the front fork component.
