Description

Technical Field

[0002] At present, most of the new energy vehicles sold on the market are hybrid electric vehicles and pure electric vehicles. In order to rapidly attenuate the vibration of the vehicle frame and the body and improve the ride comfort and smoothness of the vehicle, multiple groups of shock absorbers are installed on the body of the new energy vehicle.

[0003] The existing patent document with the publication number CN208778556U provides a shock absorber for new energy vehicles. The setting of the fixed shaft and the first adjustment bolt in this utility model is beneficial to the installation of the device; the setting of the buffer spring is beneficial to buffering and avoiding damage to the device; the setting of the second anti-slip pad is beneficial to increasing friction and avoiding harm caused by the sliding of the device.

[0004] However, when the existing shock absorbers for new energy vehicles are in use, the fixed connection structure is not convenient for the staff to quickly disassemble and assemble the shock absorbers, and it is not convenient for the staff to perform maintenance operations on the shock absorption structure. When the existing shock absorbers for new energy vehicles use a spring structure as the shock absorption structure, under the repeated compression of the shock absorber, the elasticity of the spring will fail, which will directly affect the shock absorption effect during the driving of the new energy vehicle. If the shock absorber is replaced as a whole, it will relatively increase the use cost of the new energy vehicle, and the practicability is poor. Content of the Utility Model

When maintenance operations need to be performed on the shock absorber body 101, the staff uses tools to squeeze the damping piston group 105 to separate it from the embedding groove 106 and retract it into the positioning sleeve 104. Then, the staff pulls the maintenance cover plate 103 to pull out the positioning sleeve 104, and then the internal structure of the shock absorber body 101 can be maintained.

[0027] The support mechanism 2 includes a main damping sleeve group 201 and a guide plate 202. The main damping sleeve group 201 is fixedly installed at the lower end of the connecting top plate 102, and the guide plate 202 is fixedly installed at the lower end of the main damping sleeve group 201. The support mechanism 2 further includes a guide rod 203 which is fixedly installed inside the shock absorber body 101. The guide plate 202 is slidably connected to the guide rod 203. The support mechanism 2 also includes a main shock-absorbing spring 204 and a guide frame 205. The main shock-absorbing spring 204 is fixedly installed at the upper end of the guide plate 202. The main shock-absorbing spring 204 is located at the outer end of the main damping sleeve group 201. The upper end of the main shock-absorbing spring 204 is fixedly connected to the connecting top plate 102. The guide frame 205 is movably installed at the outer end of the guide rod 203. The guide frame 205 is located at the lower end of the guide plate 202. The support mechanism 2 also includes a linkage rod 206 and a support guide rail 207. The linkage rod 206 is movably installed at the lower end of the guide frame 205. The support guide rail 207 is located below the guide frame 205. The support mechanism 2 also includes a guide slider 208 and a secondary shock-absorbing spring 209. The guide slider 208 is movably installed inside the support guide rail 207.

The secondary shock-absorbing spring 209 is located at the outer end of the guide slider 208. The support mechanism 2 also includes an auxiliary damping sleeve group 210 and an auxiliary shock-absorbing spring 211. The auxiliary damping sleeve group 210 is fixedly installed at the lower end inside the shock absorber body 101. The guide frame 205 is located at the upper end of the auxiliary damping sleeve group 210. The auxiliary shock-absorbing spring 211 is fixedly installed at the lower end inside the shock absorber body 101. The auxiliary shock-absorbing spring 211 is located at the outer end of the auxiliary damping sleeve group 210. When using the shock absorber body 101 for shock absorption and protection operations of new energy vehicles, the connecting top plate 102 is stressed to squeeze the main damping sleeve group 201 and the main shock-absorbing spring 204, so that the main damping sleeve group 201 and the main shock-absorbing spring 204 are compressed, buffering the impact force received by the shock absorber body 101. The main damping sleeve group 201 and the main shock-absorbing spring 204 squeeze the guide plate 202, causing the guide plate 202 to slide on the guide rod 203. The guide plate 202 squeezes the guide frame 205, causing the guide frame 205 to slide on the guide rod 203. The guide frame 205 squeezes the linkage rod 206, and the linkage rod 206 pushes the guide slider 208 to slide inside the support guide rail 207, so that the secondary shock-absorbing spring 209 is compressed, performing secondary buffering on the impact force received by the shock absorber body 101. The support slide rail squeezes the auxiliary damping sleeve group 210, so that the auxiliary damping sleeve group 210 and the auxiliary shock-absorbing spring 211 are compressed, performing tertiary buffering on the impact force received by the shock absorber body 101, achieving the shock absorption effect. The three groups of buffering structures can reduce the load and wear on the components, and extend the service life of the shock absorber body 101.

[0028] Working principle: When using the shock absorber body 101 for shock absorption and protection operations of new energy vehicles, the connecting top plate 102 is stressed to squeeze the main damping sleeve group 201 and the main shock spring 204, causing the main damping sleeve group 201 and the main shock spring 204 to be compressed, buffering the impact force received by the shock absorber body 101. The main damping sleeve group 201 and the main shock spring 204 squeeze the guide plate 202, causing the guide plate 202 to slide on the guide rod 203. The guide plate 202 squeezes the guide frame 205, causing the guide frame 205 to slide on the guide rod 203. The guide frame 205 squeezes the linkage rod 206, and the linkage rod 206 pushes the guide slider 208 to slide inside the support rail 207, causing the auxiliary shock spring 209 to be compressed, and performing secondary buffering on the impact force received by the shock absorber body 101. The support slide rail squeezes the auxiliary damping sleeve group 210, causing the auxiliary damping sleeve group 210 and the auxiliary shock spring 211 to be compressed, and performing tertiary buffering on the impact force received by the shock absorber body 101, achieving the shock absorption effect. The three groups of buffering structures can reduce the load and wear on the components and extend the service life of the shock absorber body 101. When maintenance operations need to be performed on the shock absorber body 101, the staff uses tools to squeeze the damping piston group 105 to separate it from the embedding groove 106 and retract it into the positioning sleeve 104. Then, the staff pulls the maintenance cover plate 103 to pull out the positioning sleeve 104, and then the internal structure of the shock absorber body 101 can be maintained and repaired.
