Description

TECHNICAL FIELD

[0001] The utility model application relates to the technical field of automobile shock absorption, and specifically relates to a high-stability automobile chassis shock frame. BACKGROUND

[0002] The chassis shock frame is a key component in the automobile chassis system, mainly used for reducing or absorbing the vibration and impact force of the vehicle during driving due to uneven road surface or other external impact, and its function is to improve the comfort and stability of the vehicle and reduce the damage of vibration to the chassis and other components.

[0003] The spring washer in the existing chassis shock frame is a connecting element between the spring and the shock frame, which is usually used to reduce direct contact between metals, reduce friction, absorb impact force, and reduce noise. When the spring washer is installed between the spring and the chassis, its function is to fix the position of the spring and ensure its stability. However, during transportation and movement, the spring washer may be displaced or shaken due to the vibration, bumping or external impact of the vehicle. This shaking may cause the contact between the spring washer and the spring to become unstable, and the friction between the spring and the washer may cause the surface of the washer or the surface of the spring to gradually wear out. Long-term friction and wear may cause the spring to lose its original elastic properties, and the washer may gradually fail due to material consumption, even possibly cracking or falling off, affecting the stability and safety of the system. SUMMARY

[0026] In order to make the application purposes, features and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the embodiments described below are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0027] With reference to FIGS. 1-5, a high-stability automobile chassis shock-absorbing frame includes a shock-absorbing frame body 1, a shock-absorbing spring 2 is wound on the shock-absorbing frame body 1, a connecting support 3 is arranged at the upper and lower ends of the shock-absorbing frame body 1, a spring washer 4 is arranged on the shock-absorbing frame body 1, the spring washer 4 is connected with the shock-absorbing spring 2, a limiting assembly 5 is sleeved on the outer wall of the connecting support 3 above the spring washer 4, the limiting assembly 5 fixes the spring washer 4 at the upper end, and a reinforcing assembly 6 is arranged on the limiting assembly 5.

[0028] The limiting assembly 5 includes an auxiliary plate 51 sleeved on the outer wall of the connecting support 3, a plurality of sets of limiting rods 52 inserted into the auxiliary plate 51, a first external thread 53 formed on the outer wall of the bottom end of the limiting rod 52, a second external thread 54 formed on the outer wall of the upper end of the limiting rod 52, a fixing bolt 55 threadedly connected on the second external thread 54, a prismatic lug 56 connected on the top end of the limiting rod 52, a rotating cap 57 screwed with the prismatic lug 56, and a limiting groove 58 formed on the spring washer 4.

[0029] Specifically, when the staff needs to transport or move the shock-absorbing frame body 1, the limiting rod 52 is inserted into the limiting groove 58, and then the first external thread 53 is screwed with the limiting groove 58. It is worth noting that it is not convenient to rotate the limiting rod 52, and the rotating cap 57 can be screwed with the prismatic lug 56, and then the rotating cap 57 is rotated to drive the limiting rod 52 to rotate. At this time, the fixing bolt 55 is rotated downward, so that the fixing bolt 55 moves downward in cooperation with the second external thread 54, and finally the fixing bolt 55 is screwed with the outer wall of the auxiliary plate 51 to form a fixed connection.

[0030] It is worth noting that a rubber pad is arranged on the end surface of the fixing bolt 55 in contact with the auxiliary plate 51. The rubber pad can provide buffering, reduce direct contact between metals, thereby reducing noise and vibration, and at the same time can protect the contact surface from wear and tear, improve the durability and service life of the shock-absorbing frame, and reduce maintenance

[0031] The reinforcing assembly 6 is arranged on the side of the auxiliary plate 51 of the fixed bolt 55, the prismatic protrusion 56 is in the shape of a hexagonal prism, the inner wall of the rotating cap 57 is provided with a matching hexagonal groove, the design of the hexagonal prism provides better torque transmission and stability, so that the rotating cap 57 can be more firmly clamped with the prismatic protrusion 56, the first external thread 53 is in threaded connection with the limiting groove 58, and the threaded connection provides a reliable fixing mode, so that the limiting rod 52 cannot be loosened after installation;

[0032] The reinforcing assembly 6 comprises a sliding groove 61 arranged on the inner wall of the auxiliary plate 51, a sliding block 62 slidably connected in the sliding groove 61, a reset spring 63 arranged in the sliding groove 61, a reinforcing rod 64 connected to the outer wall of the top end of the sliding block 62, a handle 65 arranged on the outer wall of the reinforcing rod 64, and a reinforcing groove 66 arranged in the fixed bolt 55.

[0033] Before rotating the limiting rod 52, the worker needs to pull the handle 65 outward in advance, so that the handle 65 drives the reinforcing rod 64 to move outward, and the reinforcing rod 64 slides outward in the sliding groove 61 by the sliding block 62, and the reset spring 63 is deformed during the sliding process. After the reinforcing rod 64 is fixed to the fixed bolt 55, the limiting rod 52 can be rotated, and the reinforcing assembly 6 does not hinder the work of the limiting assembly 5 at this time. After the fixed bolt 55 is tightened and fixed, the worker can loosen the pulled handle 65, and the restoring force of the elasticity of the reset spring 63 pushes the reinforcing rod 64 to restore, and finally the reinforcing rod 64 is clamped with the reinforcing groove 66 in the fixed bolt 55 to form reinforcement, so that the fixed bolt 55 cannot be easily loosened.

[0034] It is worth noting that one end of the reset spring 63 is connected to the inner wall of the sliding groove 61, and the other end of the reset spring 63 is connected to the outer wall of the sliding block 62. The design of the reset spring 63 allows the reinforcing rod 64 to be released when needed, so as to rotate the limiting rod 52. The caliber of the reinforcing rod 64 is smaller than the caliber of the reinforcing groove 66. This design allows the reinforcing rod 64 to slide freely in the reinforcing groove 66 while maintaining stability. The outer wall of the handle 65 is provided with anti-skid lines, which increases the friction of the handle 65, so that the operator has a better grip when rotating the handle, reducing the risk of slipping.
