TECHNICAL FIELD
[0001] The present application relates to the field of automobile shock absorbers, in particular to an automobile shock absorber. BACKGROUND
[0002] As a key component of vehicle suspension system, the structural design and functional realization of automobile shock absorber are of great importance to improve driving comfort and vehicle stability. The automobile shock absorber is mainly composed of an outer support, a support frame and a hydraulic suspension. The hydraulic suspension, as the core damping element, is installed on the support frame, and the support frame is nested in the inner space of the outer support. This structural design aims to effectively absorb and buffer the vibration impact from the road through the hydraulic suspension, thereby improving the riding comfort and ensuring the driving stability.
[0003] However, during actual driving, especially when encountering uneven road surfaces or performing emergency braking, acceleration and other operations, the hydraulic suspension will inevitably produce significant vibration and oscillation, which may cause collision between the support frame and the outer support, resulting in surface material wear of the support frame and the outer support under long-term repeated action, thereby shortening the service life of the shock absorber. Therefore, this problem needs to be solved. CONTENT OF THE INVENTION
[0004] In order to prolong the service life of the shock absorber, the present application provides an automobile shock absorber.

[0006] An automobile shock absorber comprises an outer support, a support frame and a hydraulic suspension. The hydraulic suspension comprises a vulcanized main body. The support frame is arranged in the outer support. The vulcanized main body is connected to the inner side of the support frame. A buffer member is connected to the peripheral side of the vulcanized main body. The buffer member is wrapped around the outer peripheral side of the support frame and has a spacing between the inner side wall of the outer support. The buffer member comprises a first buffer part, a second buffer part, a third buffer part and a fourth buffer part connected in sequence. The second buffer part is connected to the peripheral side of the support member. The first buffer part and the third buffer part are respectively connected to the side of the support member close to the vulcanized main body and the side away from the vulcanized main body. The fourth buffer part is connected to one side of the second buffer part.
[0007] By adopting the above technical scheme, when the automobile is driving, the buffer member can have a certain deformation space when impacted, thereby further absorbing vibration energy. The first buffer part, the second buffer part, the third buffer part and the fourth buffer part can buffer and abut different positions on the outer side of the support frame, so that the buffer member can avoid collision of each part of the support frame and the outer support, and also play a role in buffering and damping, thereby prolonging the service life of the shock absorber.
[0008] Optionally, the first protrusion is arranged on the outer periphery of the first buffer part.
[0009] Optionally, the first protrusion is arranged at least two in the length direction of the buffer part.
[0010] Optionally, the first protrusion extends to the second buffer part.
[0011] Optionally, the second protrusion is arranged on the outer side of the second buffer part.
[0012] Optionally, the third protrusion is arranged on the outer side of the third buffer part.
[0013] Optionally, the third protrusion extends to the second buffer part.
[0014] Optionally, the fourth buffer part is arranged in a curved manner and extends away from the vulcanization main body.
[0015] Optionally, the fourth protrusion is arranged on the outer side of the fourth buffer part, and the fourth protrusion extends in the length direction of the fourth buffer part.
[0016] In summary, the present application includes at least one of the following beneficial technical effects:
[0017] 1. When the automobile is running, the buffer part can have a certain deformation space when impacted, thereby further absorbing vibration energy; through the first buffer part, the second buffer part, the third buffer part, and the fourth buffer part, different positions on the outer side of the support frame can be buffered and abutted, so that through the buffer part, the collision of the support frame and each part of the outer support frame can be avoided, and the buffer and shock absorption effect can also be achieved, thereby prolonging the service life of the shock absorber.
[0018] 2. The first protrusion extending to the second buffer part can increase the contact area between the first protrusion and the outer support frame, and the first protrusion arranged at intervals can provide a deformation space, thereby providing better buffering and shock absorption effect.
