[0047] Working principle: In the working process of the left and right rear upper swing arm support front plate, the connecting block 1 plays a core role, and the two connecting blocks 1 are symmetrically distributed to form a support structure for the entire support front plate. When stressed, the force from the vehicle body and the rear upper swing arm is transmitted and dispersed through the connecting block 1. The extension block one 3 extends from the front side of the connecting block 1, expanding the range of the connecting block 1 forward, making the connection and cooperation between components more smooth. The extension block two 4 makes the transmission path of the force in the support front plate more reasonable in the transverse and longitudinal directions. When the rear upper swing arm moves and generates force, these forces can be transmitted within the support front plate through the extension block two 4, so that the entire support front plate can better adapt to the movement and stress of the rear upper swing arm under different working conditions, ensuring that the structure remains reliable in complex stress environments. The welding flange one 5 and the welding flange two 6 increase the welding area, making the welding operation more convenient and reliable, so that the welding part is not prone to looseness or damage under the long-term action of various forces. The recessed groove 7 can cooperate with the corresponding structure on other components to limit the position of the front plate, ensuring that the support front plate is in the same and accurate position every time it is installed, thereby ensuring the consistency and stability of the entire suspension system. The recessed fulcrum groove 8 can change the direction or size of the force when the support front plate is stressed, making the distribution of the force within the support front plate more reasonable and avoiding stress concentration, thereby ensuring the performance of the entire support front plate under stress and the reliability and safety of the vehicle during driving. Through the fine adjustment mechanism 2, when the relative position of the rear upper swing arm and the vehicle body needs to be fine adjusted during the installation process, the rotating moving column 202 can be rotated to drive the upper threaded groove 204 to rotate. By using the threaded engagement of the threaded groove 204 and the spiral groove 207, the extrusion cylinder 205 is displaced to the rear side of the moving column 202, thereby releasing the extrusion of the limiting cylinder 201. Then, the moving column 202 and the attached fixed disc 203 are removed, the number of adjusting washers 209 is adjusted to change the position of the fixed disc 203, and then the moving column 202 is reinstalled along the original path and rotated again to move the extrusion cylinder 205 to the front side of the moving column 202 until it is extruded by the limiting cylinder 201. The inclined surface at the joint of the square hole 206 and the limiting cylinder 201 and the extrusion cylinder 205 causes the extrusion cylinder 205 to be extruded by the limiting cylinder 201, thereby clamping the outer wall of the moving column 202 on the front side, achieving the fixation of the extrusion cylinder 205, and ensuring that the extrusion cylinder 205 will not loosen when the support front plate is shaken.

[0048] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
