Description

Technical Field

[0001] This utility model relates to the field of automotive shock absorber wrist guard technology, specifically an automotive shock absorber wrist guard with a reinforcing rib structure. Background Technology

[0002] As a chassis component of automobiles, the shock absorber operates under extremely harsh conditions, frequently exposed to dust, mud, water, and gravel. These external factors can easily cause oil leakage and failure in the shock absorber. A common protective method is to cover the end of the shock absorber with a protective cap to protect the oil seal.

[0003] For example, the authorized announcement number "CN213899716U" describes a type of shock absorber cover. When the shock absorber wobbles, the reinforcing ribs on the cover body will first come into contact with the dust cover installed on the outside of the shock absorber, thus playing a certain guiding role through the reinforcing ribs. Existing shock absorber covers have multiple reinforcing ribs directly connected to the outer wall, and drainage holes for heat dissipation and ventilation are opened between each reinforcing rib. However, the heat dissipation effect of the drainage holes depends heavily on the spacing of the reinforcing ribs. When the spacing of the reinforcing ribs is relatively small, the drainage holes will be forced to be narrow, reducing the heat dissipation effect. However, when the spacing of the reinforcing ribs is too large, the drainage holes are more likely to be blocked by mud and sand impurities. Therefore, it is difficult to maintain the installation balance of the reinforcing ribs and drainage holes in existing shock absorber covers. Utility Model Content

[0004] This invention addresses the problem that existing shock absorber covers suffer from several drawbacks. When the spacing between the reinforcing ribs is small, the vent hole becomes narrow, reducing heat dissipation. However, when the spacing between the reinforcing ribs is too large, the vent hole is easily blocked by mud and sand. Therefore, existing shock absorber covers struggle to maintain a proper balance between the installation of the reinforcing ribs and the vent hole. This invention proposes a car shock absorber wristband with a reinforcing rib structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: Design a car shock absorber wrist guard with a reinforcing rib structure, including a shock absorber wrist guard cylinder, an inner cavity, and an anti-collision pad. The inner cavity is fixedly opened inside the shock absorber wrist guard cylinder. The outer wall of the shock absorber wrist guard cylinder is provided with an overhead reinforcing rib structure, and the outer wall of the shock absorber wrist guard cylinder is provided with a sand-proof structure with drainage holes.

[0006] This feature includes a shock absorber wrist guard made of high-strength engineering plastic through one-piece injection molding, with a wear-resistant coating on the inner wall, ensuring both lightweight design and improved wear resistance.

[0007] Preferably, the overhead reinforcing rib structure includes extension frames and reinforcing ribs. Multiple extension frames are fixedly installed at both ends of the outer wall of the shock absorber wrist guard. Reinforcing ribs are fixedly installed at the ends of two extension frames. Vertical plates are fixedly connected to the side walls of multiple reinforcing ribs. Diagonal braces are fixedly installed on both sides of the vertical plates.

[0008] In this setup, eight extension brackets are fixedly installed at both ends of the outer wall of the shock absorber wrist guard. The reinforcing ribs are made of high-strength aluminum alloy. The inner wall of the reinforcing ribs is not flush with the shock absorber wrist guard, and the cross-section of the reinforcing ribs is trapezoidal, thicker at the end closer to the extension bracket and slightly thinner at the end further away. Multiple reinforcing ribs are evenly distributed along the circumference of the outer wall of the shock absorber wrist guard, with an angle of 45 degrees between adjacent reinforcing ribs. The height of the vertical plate is consistent with the length of the reinforcing ribs. The inner wall of the diagonal brace and the reinforcing ribs form a stable triangular support structure, improving the deformation resistance of the reinforcing ribs.

[0009] Preferably, the plurality of reinforcing ribs are equidistantly distributed along the outer circumference of the shock absorber wrist guard, and the inner walls of the plurality of diagonal braces are fixedly connected to the reinforcing ribs.

[0010] Preferably, the venting hole sand-proof structure includes venting holes and welding blocks. Multiple venting holes are fixedly opened on the outer wall of the shock absorber wrist guard. Welding blocks are fixedly connected to both ends of the inner side of multiple venting holes. Sand-proof mesh is fixedly connected between multiple welding blocks.

[0011] In this configuration, the number of vent holes is the same as that of the reinforcing ribs. The vent holes are directly opened on the outer wall of the shock absorber wrist guard. The welding block is welded with a stainless steel sandproof mesh. The sandproof mesh has many holes, which can ensure that external sand and gravel will not enter the shock absorber wrist guard without obstructing the heat dissipation of the vented air.

[0012] Preferably, the plurality of sand-proof meshes are circumferentially and equidistantly distributed on the outer side of the shock absorber wrist sleeve, and the front ends of the plurality of drainage holes are arranged opposite to the inner side of the reinforcing ribs.

[0013] Preferably, an anti-collision pad is fixedly installed inside the shock absorber wrist guard, and the anti-collision pad is fixedly installed at the top of the inner cavity.

[0014] This feature includes a polyurethane foam anti-collision pad fixedly installed inside the shock absorber wrist guard, with an anti-slip texture on the surface. It is fixedly positioned at the top of the inner cavity to buffer impacts and reduce friction noise.

[0015] The present invention proposes a car shock absorber wrist guard with a reinforced rib structure, which has the following advantages: the vent hole enables airflow exchange and heat dissipation between the inside of the wrist guard and the outside, while the sand-proof mesh welded inside effectively prevents the intrusion of mud and sand impurities. The suspended design allows the reinforcing ribs to be staggered from the outer wall of the wrist guard cylinder, ensuring that the vent hole always remains unobstructed, achieving a balance between support strength and heat dissipation and sand-proof functions. The extension frame is used to separate the reinforcing ribs from the outer wall of the shock absorber wrist guard cylinder, so that the vent hole can be independent of the outer wall of the wrist guard cylinder and is not restricted by the spacing of the reinforcing ribs.

[0018] The present invention will be further described below with reference to the accompanying drawings: Example: Please refer to Figure 1-6 In this embodiment, a car shock absorber wrist guard with a reinforcing rib structure includes a shock absorber wrist guard cylinder 1, an inner cavity 2, and an anti-collision pad 3. The inner cavity 2 is fixedly opened inside the shock absorber wrist guard cylinder 1. The outer wall of the shock absorber wrist guard cylinder 1 is provided with a suspended reinforcing rib structure 4 and a drainage hole anti-sand structure 5. The anti-collision pad 3 is fixedly installed inside the shock absorber wrist guard cylinder 1 and is fixedly set at the top of the inner cavity 2. The inner cavity 2 is fixedly opened inside the shock absorber wrist guard cylinder 1. The shock absorber wrist guard cylinder 1 is integrally injection molded from high-strength engineering plastic, and the inner wall is provided with a wear-resistant coating, which ensures both lightweight and improved wear resistance. The anti-collision pad 3 made of polyurethane foam is fixedly installed inside the shock absorber wrist guard cylinder 1. The surface is provided with anti-slip texture and is fixedly set at the top of the inner cavity 2 to buffer impacts and reduce friction noise.

[0019] The overhead reinforcing rib structure 4 includes extension frames 41 and reinforcing ribs 42. Multiple extension frames 41 are fixedly installed at both ends of the outer wall of the shock absorber wrist sleeve 1. Reinforcing ribs 42 are fixedly installed at the ends of two extension frames 41. Vertical plates 43 are fixedly connected to the side walls of multiple reinforcing ribs 42. Diagonal braces 44 are fixedly installed on both sides of the vertical plates 43. Multiple reinforcing ribs 42 are equidistantly distributed along the circumference of the outer wall of the shock absorber wrist sleeve 1. The inner walls of multiple diagonal braces 44 are fixedly connected to the reinforcing ribs 42. Eight extension frames 41 are fixedly installed on the outer wall of the shock absorber wrist sleeve 1. At both ends, high-strength aluminum alloy reinforcing ribs 42 are used. The inner wall of the reinforcing ribs 42 is not attached to the shock absorber wrist sleeve 1. The cross-section of the reinforcing ribs 42 is trapezoidal, with the end closer to the extension frame 41 being thicker and the end further away being slightly thinner. Multiple reinforcing ribs 42 are distributed equidistantly along the outer circumference of the shock absorber wrist sleeve 1. The included angle between adjacent reinforcing ribs 42 is 45 degrees. The height of the vertical plate 43 is the same as the length of the reinforcing ribs 42. The inner wall of the diagonal brace 44 and the reinforcing ribs 42 form a stable triangular support structure, which improves the deformation resistance of the reinforcing ribs 42.

[0020] The venting hole sandproof structure 5 includes venting holes 51 and welding blocks 52. Multiple venting holes 51 are fixedly opened on the outer wall of the shock absorber wrist sleeve 1. Welding blocks 52 are fixedly connected to the inner ends of multiple venting holes 51. Sandproof mesh 53 is fixedly connected between multiple welding blocks 52. Multiple sandproof mesh 53 are distributed circumferentially and evenly on the outer side of the shock absorber wrist sleeve 1. The front end of multiple venting holes 51 is set opposite to the inner side of the reinforcing rib 42. The number of venting holes 51 is the same as that of the reinforcing rib 42. The venting holes 51 are directly opened on the outer wall of the shock absorber wrist sleeve 1. The welding blocks 52 are welded with stainless steel sandproof mesh 53. The sandproof mesh 53 has a large number of mesh holes, which can ensure that external sand and gravel will not enter the shock absorber wrist sleeve 1 without hindering the heat dissipation of the venting air.

[0021] Working principle: Car shock absorber wrist guards with reinforced ribs can be placed over the ends of the shock absorbers to be installed, protecting the car shock absorbers. The shock absorber wrist guard 1 is made of high-strength engineering plastic through one-piece injection molding. The inner wall is coated with a wear-resistant coating, which ensures both lightweight and improved wear resistance. The shock absorber wrist guard 1 is fixedly installed with a polyurethane foam anti-collision pad 3 with an anti-slip texture on the surface. It is fixedly installed at the top of the inner cavity 2 to buffer impact and reduce friction noise. When in use, first cover the end of the shock absorber to be installed with the inner cavity 2 through the shock absorber wrist sleeve 1. The anti-collision pad 3 fits against the top of the shock absorber to buffer and reduce noise. When the shock absorber swings during movement, the outermost reinforcing rib 42 first contacts the dust cover. The triangular support structure formed by the vertical plate 43 and the diagonal brace 44 provides stable support and guidance to prevent the dust cover from scratching the shock absorber. The drainage hole 51 allows for airflow exchange and heat dissipation between the inside of the wrist guard and the outside environment. At the same time, the sand-proof mesh 53 welded inside effectively prevents the intrusion of mud and sand impurities. The suspended design ensures that the reinforcing rib 42 is staggered from the outer wall of the wrist guard tube, ensuring that the drainage hole 51 always remains unobstructed, thus achieving a balance between support strength and heat dissipation and sand prevention functions.

[0022] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
