Description

Technical Field

[0001] This utility model belongs to the field of motorcycle technology, and in particular relates to a dustproof shock absorber for motorcycles. Background Technology

[0002] The main function of a motorcycle shock absorber is to absorb the impact caused by uneven road surfaces, provide a comfortable riding experience, and ensure the stability and handling of the motorcycle under various road conditions. It is mainly divided into two types: front shock absorbers and rear shock absorbers. For a front shock absorber, it mainly includes an outer cylinder, an inner tube, a spring, and hydraulic fluid. The spring provides vibration absorption, and the flow of hydraulic fluid dissipates vibration energy, thereby achieving the shock absorption and buffering effect. Usually, the spring and hydraulic fluid are located inside the front shock absorber. At present, in order to avoid dust causing abnormal wear to the shock absorber, a dustproof structure is also installed on the outside of the shock absorber.

[0003] A search revealed that CN222208768U, authorized on December 20, 2024, discloses a dustproof motorcycle shock absorber, including a shock-absorbing cylinder and a piston rod, as well as a dustproof mechanism. In this invention, the first and second fastening rings on the connecting sleeve and the fixing ring respectively seal and fix both ends of the sleeve to the shock-absorbing cylinder and the piston rod. Furthermore, the sealing ring inside the connecting sleeve corresponds to the sealing groove on the shock-absorbing cylinder, strengthening the seal at the connection between the shock-absorbing cylinder and the piston rod. The dust removal ring scrapes away dust from the piston rod surface as it extends and retracts inside the shock-absorbing cylinder, thus comprehensively preventing dust from entering the cylinder through the piston rod and the connection between the piston rod and the shock-absorbing cylinder. This technical solution solves the problem in the prior art where dust is difficult to remove in a timely manner, and dust is easily brought into the cylinder when the piston rod repeatedly moves in and out of the cylinder.

[0004] Existing technologies only achieve dustproof performance of shock absorbers through a sleeve, which is not very effective. Furthermore, existing technologies generate heat when the shock absorber is working, and the heat is difficult to dissipate within the sleeve. Therefore, we provide a dustproof shock absorber for motorcycles to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a dustproof shock absorber for motorcycles. The dustproof effect is further improved by using dustproof cotton, and the combination of the mounting tube and the dust filter cotton facilitates heat dissipation. This solves the problem that the existing technology only achieves the dustproof effect of the shock absorber body by using a sleeve, which is poor. In addition, the existing technology generates heat when the shock absorber is working, and the heat is not easy to dissipate inside the sleeve.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a dustproof shock absorber for motorcycles, including a shock absorber body. A dustproof mechanism is provided on the outside of the upper end of the outer cylinder of the shock absorber body. The dustproof mechanism includes symmetrically distributed dustproof cotton. A semi-circular sleeve is provided on the outside of the dustproof cotton. Connecting plates are fixed on the upper and lower side walls of the left end of the semi-circular sleeve. The connecting plates are fixedly connected to another connecting plate at the same horizontal height by bolts.

[0008] The dustproof mechanism is provided with a dustproof heat dissipation mechanism on its exterior. The dustproof heat dissipation mechanism includes a dustproof sleeve located outside the shock-absorbing outer cylinder and the shock-absorbing inner tube in the shock absorber body. An installation tube is fixed to one side of the dustproof sleeve. Dust filter cotton is provided inside the installation tube. A tube cap is threaded to the end of the installation tube away from the dustproof sleeve.

[0009] The present invention is further configured such that the dustproof cotton is semi-circular, the inner peripheral wall of the dustproof cotton is in contact with the outer peripheral wall of the shock-absorbing inner tube in the shock absorber body, and a partition is fixed below the dustproof cotton corresponding to the inner wall of the semi-circular sleeve.

[0010] The present invention is further configured such that a limiting ring is provided between the partition and the lower wall of the semi-annular sleeve, and the limiting ring is fixedly connected to the shock-absorbing outer cylinder in the shock absorber body.

[0011] The present invention is further configured such that the semi-annular sleeve is rotatably connected to another semi-annular sleeve via a hinge, the hinge being located at the end of the semi-annular sleeve away from the connecting plate.

[0012] The present invention is further configured such that mounting sleeves are provided at both the upper and lower ends of the dust cover, and the mounting sleeves are fixedly connected to the corresponding shock absorber outer cylinder and shock absorber inner tube in the shock absorber body.

[0013] The present invention is further configured such that an installation groove is formed on the outer peripheral wall of the mounting sleeve along the circumferential direction of the mounting sleeve, and an elastic ring is provided at the location of the mounting groove corresponding to the outside of the dust cover, and one end of the elastic ring is fixedly connected to the other end of the elastic ring by a screw.

[0014] The present invention is further configured such that the interior of the mounting tube communicates with the interior of the dust cover, and an annular boss is fixed on the side of the dust filter cotton away from the tube cover corresponding to the interior of the mounting tube, and the dust filter cotton is in clearance fit with the mounting tube.

[0015] The present invention is further configured such that a vent hole is provided on the side wall of the tube cover away from the dust filter cotton, and an elastic pad is provided between the inside of the tube cover and the mounting tube.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model provides installation space for the dustproof cotton by using a semi-circular sleeve and a partition. The inner circumferential wall of the dustproof cotton is in contact with the outer circumferential wall of the inner tube in the shock absorber body. This prevents dust from contaminating the inner tube and outer cylinder of the shock absorber body during relative movement, thus avoiding abnormal wear. This improves the dustproof protection of the outer circumferential wall of the inner tube in the shock absorber body, thereby enhancing the dustproof effect. This solves the problem that the existing technology only uses a sleeve to achieve the dustproof effect of the shock absorber, resulting in poor dustproof performance.

[0018] 2. This utility model, by setting up an installation pipe and a dust filter, causes the length of the dust cover to change when the inner tube and outer cylinder of the shock absorber body move relative to each other. This allows air to be drawn in and expelled from the dust cover accordingly. When air is expelled, the air inside the dust cover passes through the installation pipe, the dust filter, and the pipe cover to be discharged to the outside environment, thereby improving the heat dissipation effect on the shock absorber body inside the dust cover. The dust filter also prevents external dust from entering the dust cover, solving the problem in the prior art where the shock absorber generates heat during operation, and the heat is difficult to dissipate inside the sleeve.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0029] Example 1

[0030] Please see Figure 1-4 This utility model is a dustproof shock absorber for motorcycles, including a shock absorber body 1. The shock absorber body 1 is mainly used for front shock absorption of motorcycles. A dustproof mechanism 3 is provided on the outside of the upper end of the shock absorber outer cylinder in the shock absorber body 1. The dustproof mechanism 3 includes symmetrically distributed dustproof cotton 302 to prevent dust from accumulating above the shock absorber outer cylinder in the shock absorber body 1. A semi-circular sleeve 301 is provided on the outside of the dustproof cotton 302. It can be made of plastic. Connecting plates 301b are fixed on the upper and lower side walls of the left end of the semi-circular sleeve 301 to connect the two semi-circular sleeves 301. The connecting plate 301b is fixedly connected to another connecting plate 301b at the same horizontal height by bolts.

[0031] Specifically, the dustproof cotton 302 is semi-circular and is adapted to the semi-circular sleeve 301. The inner peripheral wall of the dustproof cotton 302 is in contact with the outer peripheral wall of the shock-absorbing inner tube in the shock absorber body 1. A partition plate 301a is fixed below the dustproof cotton 302 corresponding to the inner wall of the semi-circular sleeve 301, which can fix the position of the dustproof cotton 302 relative to the corresponding semi-circular sleeve.

[0032] A limiting ring 101 is provided between the partition 301a and the lower wall of the semi-annular sleeve 301 to limit the semi-annular sleeve 301 and prevent the semi-annular sleeve 301 from moving along the axial direction of the shock absorber body 1. The limiting ring 101 is fixedly connected to the shock absorber outer cylinder in the shock absorber body 1.

[0033] The semi-circular sleeve 301 is rotatably connected to the other semi-circular sleeve 301 via a hinge 303. The hinge 303 is located at the end of the semi-circular sleeve 301 away from the connecting plate 301b. The above arrangement makes it easy to connect the two semi-circular sleeves 301 to facilitate the disassembly and assembly of the annular sleeve and the shock absorber body 1, so as to facilitate the replacement of the dustproof cotton 302.

[0034] The operation process of this embodiment is as follows: During installation, two dustproof cotton 302 are inserted between the partition plate 301a and the upper wall inside the semi-annular sleeve 301. The semi-annular sleeve 301 is then fitted onto the outside of the shock absorber body 1, and the space between the partition plate 301a and the lower wall inside the semi-annular sleeve 301 is at the same height as the limiting ring 101. At this time, the two semi-annular sleeves 301 are closed, and then the two semi-annular sleeves 301 are fixed together by tightening the screws 304. At this time, the inner peripheral wall of the dustproof cotton 302 contacts the outer peripheral wall of the shock-absorbing inner tube in the shock absorber body 1 to achieve further dust prevention.

[0035] Example 2

[0036] Please see Figure 1 , 5 6. This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs from the first embodiment in that: a dustproof and heat dissipation mechanism 2 is provided outside the dustproof mechanism 3. The dustproof and heat dissipation mechanism 2 includes a dustproof sleeve 201 located outside the outer shock-absorbing cylinder and the inner shock-absorbing tube in the shock-absorbing body 1. The dustproof sleeve 201 is made of soft rubber material and is used for dust prevention between the inner shock-absorbing tube and the outer shock-absorbing cylinder in the shock-absorbing body 1. The dustproof sleeve 201 can be a rubber corrugated sleeve. At the same time, to prevent the shock-absorbing body 1 from using When a long relative movement occurs, the length of the dust cover 201 needs to have a certain redundancy to avoid tearing the dust cover 201. An installation tube 205 made of plastic is fixed to one side of the dust cover 201 and is integrally formed with the dust cover 201. The inside of the installation tube 205 is equipped with a dust filter cotton 203 to filter dust from the air entering the dust cover 201 to prevent dust from entering the dust cover 201. The end of the installation tube 205 away from the dust cover 201 is threaded with a tube cap 204 made of plastic.

[0037] Specifically, the dust cover 201 has mounting sleeves 102 at both the top and bottom ends to facilitate the installation of the dust cover 201. The mounting sleeves 102 are fixedly connected to the corresponding shock absorber body 1 shock absorber outer cylinder and shock absorber body 1 shock absorber inner tube.

[0038] The outer peripheral wall of the mounting sleeve 102 is provided with a mounting groove 102a along the circumferential direction of the mounting sleeve 102. The two ends of the dust cover 201 are respectively located inside the two mounting grooves 102a, which can prevent the two ends of the dust cover 201 from moving to a certain extent. An elastic ring 206 is provided at the location of the mounting groove 102a corresponding to the outside of the dust cover 201. One end of the elastic ring 206 is fixedly connected to the other end of the elastic ring 206 by a screw 206a. The two ends of the dust cover 201 can be fixed by locking the two ends of the elastic ring 206 by the screw 206a.

[0039] The interior of the mounting tube 205 is connected to the interior of the dust cover 201, allowing airflow to pass through when the shock absorber body 1 is working. The side of the dust filter cotton 203 away from the tube cover 204 has an annular boss 205a fixed inside the mounting tube 205 to limit the dust filter cotton 203 and prevent the dust filter cotton 203 from entering the interior of the dust cover 201. The dust filter cotton 203 and the mounting tube 205 are fitted with a clearance.

[0040] A ventilation hole is provided on the side wall of the tube cover 204 away from the filter cotton 203 to facilitate airflow through the tube cover 204. An elastic pad 202 is provided between the inside of the tube cover 204 and the installation tube 205. Its elasticity can prevent the tube cover 204 from rotating to a certain extent.

[0041] The remaining structure is the same as in Example 1;

[0042] The operation process of this embodiment is as follows: After the dustproof mechanism 3 is installed, the dustproof sleeve 201 is put on the outside of the shock absorber body 1. At this time, the upper and lower ends of the dustproof sleeve 201 are respectively put on the outside of the mounting sleeve 102. Then, the elastic ring 206 is put on the outside of the dustproof sleeve 201 at the position of the mounting groove 102a. Then, the screw 206a is used to lock the two ends of the elastic ring 206. The dust filter cotton 203 is inserted into the mounting tube 205. Then, the tube cover 204 is threadedly connected to the mounting tube 205.

[0043] When it is necessary to replace the dustproof cotton 302 in the dustproof mechanism 3, the screw 304 located on the lower side is removed, the elastic ring 206 located on the lower side is removed, and the lower end of the dustproof cover 201 is moved up to expose the dustproof mechanism 3, so that the dustproof cotton 302 can be replaced.

[0044] In actual use, when the shock absorber body 1 is in use, the outer cylinder and inner tube of the shock absorber body 1 move relative to each other. At this time, the length of the dust cover 201 changes accordingly. When the length of the dust cover 201 increases, outside air passes through the tube cover 204 and the dust filter cotton 203 and enters the dust cover 201. When the length of the dust cover 201 decreases, the air inside the dust cover 201 passes through the dust filter cotton 203 and the tube cover 204 and is discharged to the outside environment to achieve heat dissipation.
