Description

Technical Field

[0001] The present application relates to the technical field of automobile parts, and in particular to an automobile protective cover and a shock absorber support seat. Background Art

[0002] The shock absorber is one of the important parts of a car. It is used to alleviate the impact caused by the road surface and can quickly absorb the vibration caused by bumps, so that the vehicle can return to normal driving state. The shock absorber absorbs the energy generated by the impact of the road surface through the damping force it generates during the driving process of the vehicle. In order to continuously maintain a large damping force, an elastic limit block is usually set in the shock absorber. In order to install the limit block on the shock absorber, it is necessary to fix a support seat on the shock absorber piston rod to support the limit block. During the operation of the shock absorber, the buffer seat is often subjected to a large repeated impact force. In order to fix the support seat on the piston rod, the current method is to process an annular groove on the piston rod, clamp the spring retaining ring in the annular groove, and the support seat is sleeved on the piston rod. At this time, the spring retaining ring limits the axial movement of the support seat.

[0003] Related prior art, such as Chinese patent application "Support seat of shock absorber in wheel suspension of vehicle", application number: CN201880014123.7, discloses that the support seat has a support seat flange supported and fixed on the vehicle body structure in a force-locking manner, the support seat flange surrounds an elastic element of an engagement ring, and the shock absorber piston rod is suspended in the elastic element. Here, the support seat flange passes through a through opening in the vehicle body structure using a flange in an annular shape and forming a hollow cylinder (the cylinder axis of the flange at least approximately coincides with the longitudinal axis (L) of the shock absorber), so that a support seat cover that can be tightened and has a nut or a support seat cover constructed in the form of a lock nut can be tightened on the thread arranged on the outer wall of the flange, and the support seat nut or the support seat cover is supported on the vehicle body structure with a clamping auxiliary element in the middle, and the support seat flange is tightened toward the vehicle body structure, so that the edge ring section of the vehicle body structure surrounding the through opening is clamped between the support seat flange and the clamping auxiliary element and the final nut or support seat cover.

[0004] A protective cover needs to be installed on the shock absorber support seat. The existing protective cover is usually designed with an internal claw structure to achieve installation and clamping connection with the shock absorber support seat. However, the inventor of the present application took into account that the protective cover is injection molded, and the internal claws are easily torn when forced to demold. Therefore, inclined demolding is required, which makes the mold structure complicated and the cost is high. Utility Model Content

[0005] The technical problem to be solved by the present application is to provide an automobile protective cover and a shock absorber support seat, further optimize the structure of the dust cover, and reduce the production cost of the product; the assembly force and extraction force of the protective cover and the support seat are stable, and the sealing and dustproof effect is better.

[0006] The technical solution adopted in the present application is: a car protective cover, including a main body of a cylindrical structure with a sealed top surface, an opening on the bottom surface of the main body, and the bottom of the main body extending downward to form a plurality of clips, the plurality of clips are evenly distributed around the main body, and there is a spacing between two adjacent clips, and a clip protrusion is provided on the outer peripheral surface of the clip, and the bottom of the main body extends into the mounting hole of the support seat, and the clip protrusion acts on the wall surface of the mounting hole of the support seat.

[0007] Compared with the prior art, the advantages of the present application are that, firstly, the present application adopts a downward extension at the bottom of the main body to form a clamping foot, and there is a spacing between two adjacent clamping feet, so that the clamping foot has a certain elastic deformation ability when subjected to force, thereby making the assembly force and the extraction force stable. Secondly, the outer peripheral surface of the clamping foot designed in the present application has a clamping protrusion, which solves the problem of the clamping claw being pulled off when the product is demolded, and the molding mold does not need to be designed with a slanted top, the mold structure is simpler, and the production cost of the product is reduced. Thirdly, the adjustment of the assembly force and the extraction force of the present application can be achieved simply by changing the outer diameter of the clamping protrusion. Increasing the clamping claw on the existing clamping claw structure will cause demolding difficulties. In addition, when the present application is in use, the bottom of the main body extends into the mounting hole of the support seat, which can achieve a good sealing and dustproof effect.

[0008] In some embodiments of the present application, a plurality of reinforcing ribs are arranged on the outer circumference of the main body, and the outer diameter formed by the plurality of reinforcing ribs is larger than the hole diameter of the mounting hole of the support seat. In the present application, the reinforcing ribs play the role of limiting the block to prevent the automobile protective cover from being excessively inserted into the mounting hole of the support seat.

[0009] In some embodiments of the present application, the reinforcing ribs are protrudingly arranged on the surface of the main body, the reinforcing ribs are arranged parallel to the axial direction of the main body, the reinforcing ribs are located directly above the clamping feet, and there is a predetermined spacing between the reinforcing ribs and the bottom surface of the main body. In the present application, in addition to the role of limiting the blocking, the reinforcing ribs also play a role in strengthening the structural strength. Therefore, it is designed to be arranged parallel to the axial direction of the main body, and located directly above the supporting feet. It is designed that there is a predetermined spacing between the reinforcing ribs and the bottom surface of the main body, and this spacing determines the distance that the bottom of the main body extends into the mounting hole of the support seat.

[0010] In some embodiments of the present application, the clamping foot is in an inverted trapezoidal structure as a whole, the clamping protrusion is arranged along the bottom edge of the clamping foot, and the bottom surface of the clamping protrusion is an inclined guide surface. In the present application, the clamping protrusion constitutes an inverted buckle structure, and the bottom surface of the clamping protrusion is an inclined guide surface, which facilitates the assembly of the automobile protective cover and the support seat and is not easy to fall out.

[0011] In some embodiments of the present application, the top surface of the main body is a hemispherical structure, and the top surface of the main body transitions smoothly to the outer peripheral surface. The top surface of the above structure can well prevent dust from accumulating on the main body and keep it relatively clean.

[0012] A shock absorber support seat comprises a pressing plate and a protective cover. The pressing plate is provided with a mounting hole, and the protective cover is clamped with the mounting hole.

[0013] In some embodiments of the present application, the inner wall surface of the mounting hole is provided with a circle of ridges, the ridges are arranged close to the top surface of the mounting hole, and the ridges are in a circular ring structure. In the present application, the ridges are added to cooperate with the protrusions of the protective cover to achieve snap connection. If the ridges are in a circular ring structure, the protective cover can be snapped into the mounting hole at any angle, simplifying the assembly of the product.

[0014] In some embodiments of the present application, the outer surface of the bottom of the main body is fitted with the inner wall of the ridge, and the cam is buckled under the ridge; the outer surface of the bottom of the main body and the inner wall of the ridge are sealed by adhesive.
