For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0036] In order to rapidly attenuate the vibrations between the vehicle frame and the vehicle body and improve the ride smoothness and comfort of the vehicle, shock absorbers are generally installed on the vehicle suspension system. The shock absorbers are usually connected to the vehicle body and the steering knuckle, mainly transmitting the vertical load between the steering knuckle and the vehicle body. Under extreme conditions, the load transmitted by the shock absorber is relatively large. Therefore, a buffer block with a buffering function is provided on the shock absorber.

[0037] The buffer block is provided with a threaded structure. When the vehicle is running, especially when driving on roads such as mountains and seas, heavier impurities such as stones on the ground are likely to splash up. The externally exposed shock absorber is easily impacted by heavier impurities such as stones. In particular, the buffer block is prone to getting stuck with stones. When components such as the buffer block are continuously impacted for a long time, it is easy to form more depressions and other impact damages on the surface, resulting in damage to the shock absorber and affecting the shock absorption effect.

[0038] Based on this, an embodiment of the present application provides a protective device 100 for protecting structures such as the buffer block of the shock absorber, ensuring the safe use of the shock absorber and the shock absorption effect.

[0039] Please refer to Figures 1 to 5 As shown, a protective device 100 provided in an embodiment of the present application is used for a shock absorber. The shock absorber includes a connected seat body 200 and a buffer block 300. The protective device 100 includes a protective member 10 and a connecting member 20. The protective member 10 encloses to form a concave cavity 10a. The protective member 10 includes a base portion 11 and a shielding portion 12 distributed along a first direction X. One end of the shielding portion 12 is connected to the base portion 11 and the other end extends in a direction away from the base portion 11. Along the first direction X, the orthographic projection of the shielding portion 12 is located outside the orthographic projection of the base portion 11. The base portion is configured to abut against the seat body 200, and the concave cavity 10a is configured to accommodate the buffer block 300. The protective member 10 is provided with two or more connecting members 20, and each connecting member 20 is provided with a connection hole 21. The connecting member 20 is configured to be connected to the seat body 200.

[0043] The base part 11 and the shielding part 12 may intersect and be connected to each other.

[0044] Along the first direction X, it can be understood that the orthographic projection of the shielding part 12 is located on the periphery of the orthographic projection of the base part 11, that is, the shielding part 12 is arranged around the periphery of the base part 11, and the shielding part 12 protrudes from the concave cavity 10a relative to the base part 11 to the side away from the concave cavity 10a.

[0045] The number of the connecting members 20 may be two, three or more. Each connecting member 20 is provided with a connecting hole 21. The connecting member 20 can be connected to the seat body 200 of the shock absorber through a fastener 400 inserted into the connecting hole 21.

[0047] For the protection device 100 provided in an embodiment of the present application, since it includes a protection member 10 and a connecting member 20, the protection member 10 encloses a concave cavity 10a. The protection member 10 includes a base part 11 and a shielding part 12 distributed along the first direction X. One end of the shielding part 12 is connected to the base part 11 and the other end extends in a direction away from the base part 11. There are more than two connecting members 20 arranged on the protection member 10. When the protection device 100 is used for a shock absorber, it can cooperate with the seat body 200 through a fastener 400 inserted into the connecting hole 21 of each connecting member 20, abut against the seat body 200 through the base part 11, and accommodate a buffer block 300 through the concave cavity 10a, so that heavier impurities such as flying stones can be blocked by the protection device 100, protecting structures such as the buffer block 300, and ensuring the use safety and shock absorption effect of the shock absorber.

[0049] The axis of the arc-shaped plate segment 111 can be understood as the axis corresponding to the inner arc surface or the outer arc surface of the arc-shaped plate segment 111.

[0050] At both ends of the arc-shaped plate segment 111 around its own axis, a connector 20 can be respectively arranged. Of course, more than two connectors 20 can also be respectively arranged, and specifically, it can be determined according to the connectable positions on the base part 11.

[0051] For the protection device 100 provided by an embodiment of the present application, by making the base part 11 include the arc-shaped plate segment 111 and arranging connectors 20 at both ends of the arc-shaped plate segment 111 around its own axis, the shape of the arc-shaped plate segment 111 can be adapted to the shape of the seat body 200, so that when the protection device 100 is used for a shock absorber, it can fit with the seat body 200, reduce the gap between it and the seat body 200, and reduce the probability that heavier impurities such as splashing stones enter and get stuck on structures such as the buffer block 300 from the gap between the base part 11 and the seat body 200.

[0052] By arranging connectors 20 at both ends of the arc-shaped plate segment 111 around its own axis, and connecting the shielding part 12 to the arc-shaped plate segment 111 and the connectors 20, the protection device 100 can be connected and fixed to the seat body 200 through the connectors 20 at both ends, ensuring the connection strength and temperature resistance between the protection device 100 and the seat body 200, and ensuring the protection effect.

At the same time, the above-mentioned setting method can increase the volume of the cavity 10a, and when used for a shock absorber, it is beneficial to make way for the corresponding buffer block 300, thereby reducing the difficulty of assembly on the basis of ensuring the shielding and protection requirements, and avoiding installation interference and other problems.
