[0040] Embodiment 1:

[0041] According to an aspect of the present disclosure, a damper 1 is designed, Figure 1 shows a perspective view of the damper, Figure 2 shows an exploded view of the damper, asFigure 1 As shown in the figure, the shock absorber 1 comprises an upper cover plate 2, a lower bottom plate 3, an inner scissor frame 4, an outer scissor frame 5, an upper roller 6, an upper track 7, a lower roller 8, a lower track 9, a damper 10, a compression spring 11; the upper cover plate 2 is provided with a plurality of fixing ends 12 and a clamping groove 13, and the lower bottom plate 3 is provided with a plurality of fixing ends 12 and a clamping groove 13.

[0042] It can be seen that the shock absorber has simple structure, low cost, convenient installation, and the compression spring design can ensure that the shock absorber is suitable for more severe environments.

[0043] In some embodiments of the present application, Figure 3 The coverless shock absorber is shown in the figure, and Figure 3 As shown, the upper cover plate 2 is fixedly connected with the upper track 7, and the lower bottom plate 3 is fixedly connected with the lower track 9.

[0044] It can be seen that the design of the track can effectively limit the movement direction of the scissor frame, ensure that the shock absorber moves according to the preset movement direction, and realize the energy absorption and shock absorption effect.

[0045] In some embodiments of the present application, as shown in the figure, Figure 3 As shown, one end of the inner scissor frame 4 is rotatably connected with the upper roller 6, and the other end of the inner scissor frame 4 is rotatably connected with the fixing end of the lower bottom plate 3.

[0046] In some embodiments of the present application, as shown in the figure, Figure 3 As shown, one end of the outer scissor frame 5 is rotatably connected with the lower roller 8, and the other end of the outer scissor frame 5 is rotatably connected with the upper cover plate 2.

[0047] In some embodiments of the present application, as shown in the figure, Figure 3 As shown, the upper roller 6 rolls along the upper track 7, and the lower roller 8 rolls along the lower track 9.

[0048] It can be seen that this connection mode is conducive to the adjustment of the height of the shock absorber itself, and the use of rolling connection box and rotary connection can reduce the wear and tear caused by the wear and tear of components, and maximize the service life of the shock absorber.

[0049] In some embodiments of the present application, as shown in the figure, Figure 3 As shown, one end of the damper 10 is fixedly connected with the upper cover plate 2, and the other end of the damper 10 is fixedly connected with the lower bottom plate 3.

[0050] It can be seen that the setting of the damper not only can play the role of energy absorption and shock absorption, but also can prevent the problem of too fast vibration of the shock absorber caused by too strong instantaneous impact force.

[0051] In some embodiments of the present application, as shown in the figure, Figure 2As shown, the compression spring 11 is a spring of special material, and the elastic coefficient of the compression spring 11 is related to the material of the compression spring.

[0052] Specifically, as shown in Figure 1 and Figure 3 the compression spring 11 is limited in the upper cover plate 2 clamping groove 13 and the lower bottom plate 3 clamping groove 13, and the compression spring 11 can be telescopic with the upper cover plate 2 and the lower bottom plate 3.

[0053] It can be seen that the compression spring is the main energy absorption mechanism of the shock absorber, and the compression spring design can not only save cost under the condition of ensuring function, but also can cope with more severe environment. The length of the compression spring itself can be set randomly in advance, which means that the stroke of the shock absorber can be selected according to actual needs.

[0054] According to another aspect of the present application, a kind of automobile seat 14 is designed, as shown in Figure 4 , the automobile seat 14 includes the above-mentioned any kind of shock absorber 1.

[0055] In summary, compared with the traditional shock absorber, the shock absorber has simpler structure, lower cost and more convenient later maintenance. The design of the compression spring not only ensures the damping characteristics of the shock absorber, but also can select the length to adjust the stroke of the shock absorber according to actual situation. The automobile seat using the shock absorber can adapt to most light trucks, and can solve the problem that most light trucks cannot install shock absorber to the greatest extent, so that light truck users can also enjoy comfortable driving experience.

[0056] The above is only the preferred embodiment of the present application, and is not used to limit the protection scope of the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application are included in the protection scope of the present application.
