[0002] Shock absorbers are the main shock absorbing components on vehicles such as motorcycles and cars. Figure 1 , 2 As shown, the upper end of the existing shock absorber end cover (1') is designed with 4 top grooves (2') and 4 side grooves (3') are designed on the side. The design depth of the 4 side grooves is 9.5mm, which does not reach the position of the oil absorption felt (4'), making it difficult to discharge dirt and oil. The top groove at the upper end of the end cover is designed to be deeper, with a depth of 2.5mm. The oil absorption felt has a larger contact area with the outside world, and stains are easily accumulated and blocked, scratching the piston rod, causing oil leakage in the shock absorber.

[0005] As a further technical solution, a plurality of groups of heat dissipation holes are evenly distributed along the circumferential direction on the outer wall of the body.

[0006] As a further technical solution, each group of heat dissipation holes has four and are distributed along the axial direction of the body.

[0007] As a further technical solution, there are four side grooves in total, and each side groove is connected to a corresponding group of heat dissipation holes.

[0011] 1. Deepen the depth of the four side grooves to the upper part of the end cover (connected to the top wall), and also open four upper grooves in the upper part of the end cover, which can connect the side grooves and the central hole, so that oil stains, fine dust, and sand grains can be discharged along the grooves;

[0012] 2. Cancel the design of the four grooves at the top of the end cover, reduce the contact area between the oil-absorbing felt and the outside world and the problem of stain accumulation, and can also strengthen the strength of the end cover to avoid the end cover from cracking due to excessive pressure during the compression movement of the shock absorber buffer block;

[0014] 4. Add a design of heat dissipation holes around the end cover, which is easy to dissipate heat from the shock absorber, avoid the risk of rubber deformation and aging caused by too high temperature of the oil seal, and improve the service life of the shock absorber.

[0023] The following will introduce the present utility model in detail with reference to the drawings:

[0024] Embodiment: As shown in the attached Figures 3 to 6As shown, this shock absorber end cap that is easy to drain sewage and exhaust gas and has better heat dissipation includes a body 1, an upper end face 2, a lower end face 3, a top wall 4, a central hole 5, an upper groove 6, a side groove 7, an exhaust hole 8, and a heat dissipation hole 9.

[0025] Refer to the attached Figure 3 , 4 , the body 1 adopts a cap-like structure, a central hole 5 is opened in the center of the body 1, and four side grooves 7 (four in this embodiment, or other quantities can also be used) are axially opened along the inner wall of the body 1. The four side grooves 7 are evenly distributed along the circumferential direction of the inner wall of the body 1 (as Figure 6 shown), and each side groove 7 communicates the lower end face 3 of the body 1 with the top wall 4 of the body 1. Further, four upper grooves 6 are radially opened on the top wall 4, and the positions of the upper grooves 6 correspond to the side grooves 7 one by one, so as to communicate the side grooves 7 with the central hole 5, enabling oil stains, fine dust, and sand grains to be discharged along the grooves.

[0026] Preferably, a plurality of groups of heat dissipation holes 9 are evenly distributed along the circumferential direction on the outer wall of the body 1. Each group of heat dissipation holes 9 has four, and they are distributed along the axial direction of the body 1. Further, each side groove 7 corresponds to and communicates with a group of heat dissipation holes 9. It is easy for the shock absorber to dissipate heat, avoiding the risk of rubber deformation and aging caused by too high an oil seal temperature, and improving the service life of the shock absorber.

[0027] As Figure 5 , 6 shown, four groups of exhaust holes 8 are evenly distributed along the circumferential direction on the upper end face 2 of the body 1. Each group of exhaust holes 8 has two, and they are distributed along the radial direction of the body 1. Preferably, the exhaust holes 8 and the upper grooves 6 are staggeredly distributed.

[0028] The present utility model cancels the design of 4 grooves at the top of the existing end cap, reduces the problem of the contact area between the oil absorption felt and the outside world and the accumulation of stains, and can also strengthen the strength of the end cap, avoiding the end cap from cracking due to excessive pressure during the compression movement of the shock absorber buffer block. During operation, oil stains, fine dust, sand grains, etc. can be discharged into the upper grooves 6 along the side grooves 7, and then discharged from the central hole 5 through the upper grooves 6. The exhaust holes 8 and the heat dissipation holes 9 play the roles of heat dissipation and exhaust. When the shock absorber buffer block is compressed, it is easy to exhaust gas, reducing the risk of abnormal noise. At the same time, it is easy for the shock absorber to dissipate heat, avoiding the risk of rubber deformation and aging caused by too high an oil seal temperature, and improving the service life of the shock absorber.
