The shock absorber assembly and the vehicle provided by the embodiments of the present application are described in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

As shown in fig. 1-2, the present application provides a shock absorber assembly, which includes a support 100, a shock absorber 200, and a dust cover 300, wherein a first end 310 of the dust cover 300 is connected to the support 100, a second end 320 of the dust cover 300 is a free end, the dust cover 300 has a receiving cavity, the free end is provided with an opening, one end of the shock absorber 200 extends to the receiving cavity through the opening, so that a part of the shock absorber 200 is located in the receiving cavity, thereby protecting the precise structures such as the cylinder, the piston rod, and the oil seal of the shock absorber 200. The free end is provided with the reinforcing rib 400, so that the strength of the dust cover 300 is improved, and the dust cover 300 is prevented from being deformed in the process of assembling the shock absorber assembly or in the process of driving a vehicle. Alternatively, the cross-sectional shape of the receiving cavity in a direction perpendicular to the dust cap 300 is circular, and in this case, the dust cap 300 may have a cylindrical structure for easy manufacturing. Further, at the same time, the cross-sectional shape of the dust cover 300 and the cross-sectional shape of the shock absorber 200 may be the same, so that the gap therebetween may be controlled within a small range and the gap is relatively uniform, thereby improving the dust-proof effect.

Optionally, the reinforcing rib 400 and the dust cover 300 may be an integral structure or a split structure, so that when the reinforcing rib 400 and the dust cover 300 are an integral structure, the assembly of the shock absorber assembly is facilitated, and meanwhile, the structural strength can be further enhanced; when the reinforcing rib 400 and the dust cover 300 are of a split structure, the position of the reinforcing rib 400 at the free end can be set according to actual needs, so that the shock absorber assembly can be flexibly designed.

Since the free end is less restrained, the embodiment of the present application reduces the amount of deformation of the dust boot 300 by providing the reinforcing rib 400 at the free end of the dust boot 300 to avoid interference of the dust boot 300 with the shock absorber 200. As can be seen, the present embodiment can solve the problem that the dust cover 300 is easily deformed in the related art.

There is a fitting gap between the inner wall of dust cover 300 and the outer circumferential surface of shock absorber 200, and reinforcing ribs 400 may be provided on the inner wall of dust cover 300, and at this time, it is necessary to increase the fitting gap between the inner wall of dust cover 300 and the outer circumferential surface of shock absorber 200 to avoid interference between dust cover 300 and shock absorber 200, which increases the size and cost of dust cover 300. Therefore, the rib 400 is optionally provided on the outer peripheral surface of the free end, and the free end does not occupy the space between the inner wall of the dust cover 300 and the outer peripheral surface of the shock absorber 200, so that the strength of the dust cover 300 can be improved while ensuring a sufficient fitting clearance between the inner wall of the dust cover 300 and the outer peripheral surface of the shock absorber 200, and the free end is prevented from being deformed.

In alternative embodiments, the reinforcing rib 400 may be a block-shaped protrusion, a strip-shaped or triangular structure, etc., and is not limited herein; however, such an arrangement is not convenient for the manufacture of the reinforcing bar 400, and the reinforcing effect of such a reinforcing bar 400 is limited. Therefore, the stiffener 400 is optionally an annular structure, and the central axis of the annular structure is collinear with the central axis of the dust cover 300, i.e. the stiffener 400 is arranged around the circumference of the dust cover 300 to form a closed structure, so as to facilitate manufacturing; in addition, the reinforcing rib 400 of the annular structure is a whole, so that the continuity of the reinforcing rib is good, the performance of resisting external force of the dust cover 300 is improved, and the reinforcing effect of the reinforcing rib 400 is excellent.

In a further alternative embodiment, the number of the reinforcing ribs 400 may be one, or may be at least two, and when the number of the reinforcing ribs 400 is one, the size of the reinforcing ribs 400 needs to be increased, so as to improve the strength of the dust cover 300; optionally, the number of the reinforcing ribs 400 is at least two, the reinforcing ribs 400 include a first reinforcing rib 410 and a second reinforcing rib 420, the first reinforcing rib 410 and the second reinforcing rib 420 are arranged at an interval, the first reinforcing rib 410 is arranged on one side of the second reinforcing rib 420 close to the opening, and at this time, the sizes of the first reinforcing rib 410 and the second reinforcing rib 420 can be respectively set smaller, so that the cost and the weight of the dust cover 300 are reduced; in addition, the first reinforcing ribs 410 and the second reinforcing ribs 420 are spaced apart from each other, so that the first reinforcing ribs 410 and the second reinforcing ribs 420 are relatively distributed, the area of the region corresponding to the structure of the free end against the external force is increased, and the local deformation of the dust cover 300 is avoided.

In a further optional embodiment, the reinforcing rib 400 further includes a third reinforcing rib 430, the third reinforcing rib 430 and the second reinforcing rib 420 are disposed at an interval, and the second reinforcing rib 420 is disposed between the third reinforcing rib 430 and the first reinforcing rib 410, in this case, the area of the region where the reinforcing rib 400 can perform the reinforcing function is further increased, so as to improve the strength of the dust cover 300; in addition, the reinforcing ribs 400 can be arranged more dispersedly, so that the area of the region corresponding to the structure of the free end resisting the external force is further increased, and the deformation of the free end is avoided.

In another alternative embodiment, the distance between the first reinforcing rib 410 and the second reinforcing rib 420 is a first distance, the distance between the second reinforcing rib 420 and the third reinforcing rib 430 is a second distance, and the first distance may be greater than or less than the second distance, which is inconvenient for manufacturing the dust cover 300; optionally, the first distance is equal to the second distance to facilitate fabrication of the dust cap 300. Specific numerical values of the first distance and the second distance can be flexibly selected according to actual conditions, and the embodiment of the application does not limit the specific numerical values.

In yet another alternative embodiment, the width of the first reinforcing rib 410, the width of the second reinforcing rib 420, and the width of the third reinforcing rib 430 are all equal to facilitate manufacturing the dust cover 300, but certainly, the width of the first reinforcing rib 410, the width of the second reinforcing rib 420, and the width of the third reinforcing rib 430 may also be unequal to each other, in this case, in the process of manufacturing the dust cover 300, the dies for the first reinforcing rib 410, the second reinforcing rib 420, and the third reinforcing rib 430 need to be designed separately, which will increase the workload of the design process, so this way is not as simple as the way that the width of the first reinforcing rib 410, the width of the second reinforcing rib 420, and the width of the third reinforcing rib 430 are all equal to facilitate saving the workload of the design process. Specific values of the width of the first reinforcing rib 410, the width of the second reinforcing rib 420, and the width of the third reinforcing rib 430 may be flexibly selected according to actual situations, which is not limited in the embodiment of the present application.

Optionally, in an embodiment where the distance between the first reinforcing rib 410 and the second reinforcing rib 420 is a first distance, the distance between the second reinforcing rib 420 and the third reinforcing rib 430 is a second distance, and the first distance is equal to the second distance, the width of the first reinforcing rib 410, the width of the second reinforcing rib 420 and the width of the third reinforcing rib 430 are all equal, and the width of the first reinforcing rib 410, the width of the second reinforcing rib 420 and the width of the third reinforcing rib 430 are all greater than the first distance and the second distance, so that the width of the first reinforcing rib 410, the width of the second reinforcing rib 420 and the width of the third reinforcing rib 430 are all greater, so as to ensure the strength of the free end of the dust cover 300 to resist external force.

Since the first end 310 of the dust cover 300 is connected to the support 100, and the second end 320 is a free end, the moment arm of the free end is relatively long, the end face of the free end is relatively far away from the support 100, and when the vehicle vibrates, the end face of the free end is easily deformed by the inertia force, in an alternative embodiment, the reinforcing rib 400 is disposed adjacent to the end face of the free end, so as to increase the strength of the free end, improve the stability of the free end, reduce the deformation amount of the free end, and further avoid the interference between the free end of the dust cover 300 and the shock absorber 200.

In another alternative embodiment, the support 100 includes a seat and a buffer block, the buffer block is disposed on the seat, the buffer block is disposed opposite to the shock absorber 200, when the vehicle is vibrated, the shock absorber 200 is displaced, so that the buffer block is deformed to absorb part of the kinetic energy, and the buffer block can protect the shock absorber 200. The dust cover 300 is in interference fit with the base body, so that the connection stability of the dust cover 300 and the base body is improved; in addition, the dust cover 300 is in interference fit with the base body, and has the characteristics of simple structure, good centering property, high bearing capacity and good impact resistance.

Based on the shock absorber assembly that this application embodiment disclosed, this application embodiment also discloses a vehicle, and this vehicle includes the shock absorber assembly of any embodiment described above.

While the present embodiments have been described with reference to the accompanying drawings, it is to be understood that the invention is not limited to the precise embodiments described above, which are meant to be illustrative and not restrictive, and that various changes may be made therein by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
