Detailed implementation manners

[0029] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model will be described in detail below.

[0030] Reference will be made below to Figures 1-4 describe the shock absorber 100 according to an embodiment of the present utility model. The shock absorber 100 can be applied to a vehicle.

[0031] In conjunction with Figures 1-4 As shown, the shock absorber 100 according to the present utility model mainly includes: a cylinder barrel 10, a piston rod assembly 20, a support seat 30, and a buffer block 40.

[0032] Wherein, the piston rod assembly 20 is movably arranged in the cylinder barrel 10. The piston rod assembly 20 includes a piston rod 21. The support seat 30 and the cylinder barrel 10 are spaced apart in the up-and-down direction. The buffer block 40 is located between the support seat 30 and the cylinder barrel 10 in the up-and-down direction. The piston rod 21 sequentially penetrates through the cylinder barrel 10 and the buffer block 40 and is connected to the support seat 30.

[0033] Specifically, when the shock absorber 100 is working, the piston rod assembly 20 can move up and down in the cylinder barrel 10. Cooperating with the valve system in the shock absorber 100, the piston rod assembly 20 can compress the shock-absorbing medium in the cylinder barrel 10 to achieve the shock-absorbing effect of the shock absorber 100. Of course, an oil seal assembly and a sealing retaining ring are also arranged on the cylinder barrel 10. The piston rod 21 penetrates through the oil seal assembly and the sealing retaining ring at the same time. The oil seal assembly and the sealing retaining ring can play a sealing role.

[0034] Furthermore, the support seat 30 is used to be connected to the vehicle structure. The piston rod 21 penetrates through the cylinder barrel 10 and is connected to the support seat 30. Power is transmitted to the piston rod 21 through the support seat 30, driving the piston rod 21 and even the piston rod assembly 20 to move up and down in the cylinder barrel 10. By arranging the buffer block 40, the piston rod 21 sequentially penetrates through the cylinder barrel 10 and the buffer block 40 and is connected to the buffer block 40 and the support seat 30. In this way, the buffer block 40 can play a buffering role between the cylinder barrel 10 and the support seat 30, avoiding the over-position movement of the piston rod 21 and the collision between the cylinder barrel 10 and the support seat 30, so as to reduce the impact noise generated during the shock absorption process of the shock absorber 100 and improve the driving comfort of the vehicle.

[0035] Combined with Figure 2 and Figure 4 As shown, the buffer block 40 may mainly include a first buffer portion 41 and a second buffer portion 42 which are connected to each other. On the side of the first buffer portion 41 away from the support seat 30 in the up-and-down direction, a first receiving groove 4111 is provided. One end of the second buffer portion 42 facing the first buffer portion 41 is arranged in the first receiving groove 4111. The stiffness of the second buffer portion 42 is less than that of the first buffer portion 41.

[0036] Specifically, different from setting the buffer block as an integrally formed structural member, for example, using polyurethane material to integrally foam the buffer block, the buffer block 40 of the present application is designed in a split manner, so that the buffer block 40 includes a first buffer portion 41 and a second buffer portion 42 that are connected to each other. By providing a first receiving groove 4111 on the side of the first buffer portion 41 away from the support seat 30 in the up and down direction, and disposing one end of the second buffer portion 42 facing the first buffer portion 41 in the first receiving groove 4111, it can be understood that the first buffer portion 41 is closer to the support seat 30 than the second buffer portion 42, and the second buffer portion 42 is closer to the cylinder barrel 10 than the first buffer portion 41. In this way, the first receiving groove 4111 can provide a receiving space for the compression of the second buffer portion 42.

[0037] Furthermore, by setting the stiffness of the second buffer portion 42 to be less than the stiffness of the first buffer portion 41, it can be understood that the second buffer portion 42 is more easily deformed than the first buffer portion 41. Wherein, both the first buffer portion 41 and the second buffer portion 42 can be made of polyurethane material to ensure the elasticity of the first buffer portion 41 and the second buffer portion 42. And, the density of the polyurethane material of the second buffer portion 42 can be set to be less than the density of the polyurethane material of the first buffer portion 41, so that the stiffness of the second buffer portion 42 can be less than the stiffness of the first buffer portion 41.

[0038] In this way, when the support seat 30 drives the piston rod 21 to move up and down in the cylinder barrel 10 and the support seat 30 approaches the cylinder barrel 10 and the buffer block 40 is compressed, the second buffer portion 42 will deform first, and the first receiving groove 4111 can receive the compressed and deformed second buffer portion 42. This can not only improve the compression inclination trend of the buffer block 40, ensure the buffering performance of the buffer block 40, but also improve the outward expansion trend of the buffer block 40, prevent the buffer block 40 from wrapping around the cylinder barrel 10 and being cut, and improve the durability performance of the buffer block 40. It should be noted that different stiffness combinations of the first buffer portion 41 and the second buffer portion 42 can be adopted to achieve the ideal or desired stiffness (force-displacement) performance and meet the requirements of different vehicles.

[0039] Therefore, by making the buffer block 40 include a first buffer portion 41 and a second buffer portion 42 that are connected to each other, a first receiving groove 4111 is provided on the side of the first buffer portion 41 away from the support seat 30 in the up and down direction, one end of the second buffer portion 42 facing the first buffer portion 41 is disposed in the first receiving groove 4111, and the stiffness of the second buffer portion 42 is less than the stiffness of the first buffer portion 41. When the buffer block 40 is compressed, the second buffer portion 42 is deformed first and compressed in the first receiving groove 4111, improving the compression inclination performance and the outward expansion trend of the buffer block 40, and enhancing the working performance of the buffer block 40 and even the shock absorber 100.

[0040] Combined withFigure 1 and Figure 3 As shown in Figure 3 , the first buffer part 41 may mainly include: a buffer body 411 and a connecting part 412. One end of the connecting part 412 is connected to the buffer body 411, and the other end of the connecting part 412 extends towards the second buffer part 42 and is inserted and matched with the second buffer part 42. One side of the buffer body 411 facing the second buffer part 42 is recessed in a direction away from the second buffer part 42, and the second buffer part 42 and the connecting part 412 form a first receiving groove 4111.

[0041] Specifically, by making the first buffer part 41 include the buffer body 411 and the connecting part 412, and by connecting one end of the connecting part 412 to the buffer body 411 and making the other end of the connecting part 412 extend towards the second buffer part 42, only by inserting the connecting part 412 into the second buffer part 42 and making the connecting part 412 and the second buffer part 42 be inserted and matched, the connection between the first buffer part 41 and the second buffer part 42 can be realized, and the connection between the first buffer part 41 and the second buffer part 42 can be made simpler and more reliable.

[0042] Furthermore, by making one side of the buffer body 411 facing the second buffer part 42 be recessed in a direction away from the second buffer part 42, a first receiving groove 4111 can be naturally formed between the buffer body 411 and the connecting part 412. When the connecting part 412 is inserted into the second buffer part 42 to connect the first buffer part 41 and the second buffer part 42, one end of the second buffer part 42 facing the first buffer part 41 can also naturally enter the first receiving groove 4111, thereby optimizing the structural design of the buffer block 40 and making the assembly of the buffer block 40 simpler and more convenient.

[0043] Combined with Figure 4 As shown in Figure 4 , the connecting part 412 is in a cylindrical shape. A first limiting part 4121 is arranged on the outer periphery of the connecting part 412, and a second limiting part 421 is arranged on the second buffer part 42. The first limiting part 4121 and the second limiting part 421 are in limiting cooperation.

[0044] Specifically, the connecting part 412 is in a cylindrical shape. The connecting part 412 is inserted into the second buffer part 42 and is inserted and matched with the second buffer part 42. By arranging the first limiting part 4121 on the outer periphery of the connecting part 412 and arranging the second limiting part 421 on the second buffer part 42, after the connecting part 412 is inserted into the second buffer part 42, the first limiting part 4121 can also be in limiting cooperation with the second limiting part 421, thereby restricting the relative movement of the connecting part 412 and the second buffer part 42 in the up and down directions, improving the connection stability and reliability between the first buffer part 41 and the second buffer part 42, and further making the structure of the shock absorber 100 simpler and more reliable.

[0045] Combined with Figure 4As shown, one of the first limiting portion 4121 and the second limiting portion 421 is a limiting protrusion, and the other is a limiting groove. Both the limiting protrusion and the limiting groove are annular and are in limiting cooperation with each other.

[0046] Specifically, one of the first limiting portion 4121 and the second limiting portion 421 can be set as a limiting protrusion, and the other of the first limiting portion 4121 and the second limiting portion 421 can be set as a limiting groove. In this way, only by inserting the limiting protrusion into the limiting groove, the limiting cooperation between the first limiting portion 4121 and the second limiting portion 421 can be achieved, which can make the structures of the first limiting portion 4121 and the second limiting portion 421 simpler, and can also make the realization of the limiting cooperation between the first limiting portion 4121 and the second limiting portion 421 simpler.

[0047] Furthermore, both the limiting protrusion and the limiting groove are set as annular. After the limiting protrusion and the limiting groove are in limiting cooperation, they can be in limiting cooperation with the second buffer portion 42 in the circumferential direction of the connecting portion 412. Thus, the limiting effect can be evenly distributed in the circumferential direction, and the connection stability and reliability between the first buffer portion 41 and the second buffer portion 42 can be further improved.

[0048] In a specific embodiment of the present utility model, in combination with Figure 4 As shown, the first limiting portion 4121 is a limiting protrusion, and a guiding inclined surface 4122 is provided on the side of the limiting protrusion away from the buffer body 411.

[0049] Specifically, by setting the first limiting portion 4121 as a limiting protrusion, setting the second limiting portion 421 as a limiting groove, and providing a guiding inclined surface 4122 on the side of the limiting protrusion away from the buffer body 411, when the connecting portion 412 is inserted into the second buffer portion 42, the guiding inclined surface 4122 can be in guiding cooperation with the second buffer portion 42, thereby avoiding the influence of the setting of the limiting protrusion on the insertion of the connecting portion 412 and making the insertion of the connecting portion 412 smoother.

[0050] In combination with Figure 2 and Figure 4 As shown, the shock absorber 100 may further include: a bracket 43, the bracket 43 is connected to the piston rod 21 and is located on the side of the first buffer portion 41 facing the support seat 30. The support seat 30 is provided with a mounting hole 31, the piston rod 21 passes through the mounting hole 31 and is connected to the support seat 30, and the projection of the mounting hole 31 in the up-down direction falls within the projection of the bracket 43 in the up-down direction.

[0051] Specifically, the support base 30 is provided with a mounting hole 31. The piston rod 21 passes through the mounting hole 31 and is connected to the support base 30. When the buffer block 40 is compressed, excessive expansion deformation may occur, causing some of the buffer blocks 40 to be squeezed into the mounting hole 31 and cut, resulting in the buffer block 40 being unable to work properly.

[0052] By providing a bracket 43, the bracket 43 is located on the side of the first buffer portion 41 facing the support base 30. In this way, the bracket 43 can be located between the first buffer portion 41 and the support base 30 in the up and down direction. Connecting the bracket 43 to the piston rod 21 can achieve the connection between the buffer block 40 and the piston rod 21.

[0053] And by making the projection of the mounting hole 31 in the up and down direction fall within the projection of the bracket 43 in the up and down direction, the bracket 43 can completely block the mounting hole 31. Since the bracket 43 is a rigid structure, the bracket 43 will not deform due to force during the operation of the shock absorber 100, thereby preventing the buffer block 40 from being squeezed into the mounting hole 31 and ensuring the normal operation of the buffer block 40.

[0054] Combined with Figure 4 As shown, the first buffer portion 41 is provided with a second receiving groove 4112. The bracket 43 is disposed in the second receiving groove 4112 and is in contact with the first buffer portion 41. The side of the bracket 43 close to the support base 30 is in contact with the support base 30.

[0055] Specifically, by providing a second receiving groove 4112 on the side of the first buffer portion 41 facing the support base 30, the bracket 43 can be disposed in the first receiving groove 4111, so that the side of the bracket 43 facing the first buffer portion 41 is in contact with the inner wall of the first receiving groove 4111, and the side of the bracket 43 close to the support base 30 is in contact with the support base 30. In this way, the bracket 43 can be located between the first buffer portion 41 and the support base 30. The two sides of the bracket 43 in the up and down direction are respectively in contact with the first buffer portion 41 and the support base 30, and there is no gap between the bracket 43 and the support base 30. Thus, it is possible to prevent the first buffer portion 41 from being squeezed into the mounting hole 31 through the gap between the bracket 43 and the support base 30, and more reliably prevent the buffer block 40 from being squeezed into the mounting hole 31, ensuring the buffering effect of the buffer block 40.

[0056] Furthermore, combined with Figure 4As shown, the bracket 43 is conical, and the cross-section of the bracket 43 gradually decreases on the side close to the first buffer portion 41 in the up-down direction. In this way, not only can the sharp structure at the contact position between the bracket 43 and the first buffer portion 41 be avoided, preventing the first buffer portion 41 from being cut by the sharp structure of the bracket 43 when being pressed and deformed towards the bracket 43, but also the contact area between the bracket 43 and the first buffer portion 41 can be increased, improving the blocking effect of the bracket 43 on the first buffer portion 41, thereby more reliably ensuring the normal operation of the buffer block 40 and enhancing the working performance of the buffer block 40 and even the shock absorber 100.

[0057] In some embodiments of the present utility model, the bracket 43 is in interference fit with the piston rod 21. Specifically, by making the bracket 43 in interference fit with the piston rod 21, the connection between the bracket 43 and the piston rod 21 can be achieved without additional auxiliary installation structures, and the connection stability and reliability between the bracket 43 and the piston rod 21 can be ensured. Moreover, by making the bracket 43 in interference fit with the piston rod 21, the gap between the bracket 43 and the piston rod 21 can be prevented, thereby preventing the buffer block 40 from being squeezed into the gap between the bracket 43 and the piston rod 21, and further ensuring the normal operation of the buffer block 40.

[0058] The vehicle according to the present utility model mainly includes: the above-mentioned shock absorber 100. Specifically, the durability performance and working performance of the shock absorber 100 of the present application are better. By applying the shock absorber 100 to the vehicle, the product competitiveness of the vehicle can be improved and the user experience can be enhanced.
