Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to an inverted shock absorber structure for motorcycles. Background Art

[0002] Inverted shock absorbers are usually used on high-performance motorcycles that require higher stability and responsiveness. Since the structure of the inverted shock absorber reduces the non-suspension mass, the motorcycle has better handling and responsiveness, and can reduce uncontrolled movement during collisions. It provides better suspension performance, better response speed, stability and control performance, making riding more stable and comfortable. Although the shock absorption effect gradually improves during the use of the shock absorber, the outer wall of the moving parts is not protected and is prone to wear.

[0003] A Chinese patent discloses an inverted shock absorber (authorization announcement number CN214742993U). The patented technology includes an outer cylinder, an embedded mechanism is installed on the top of the outer cylinder, and the top of the embedded mechanism is bolted to a docking joint, a groove is opened inside the outer cylinder, and the top of the inner wall of the groove is bolted to an inner rod; the utility model is fixed to the vehicle through the docking joint and the connecting head, the embedded mechanism is installed on the top of the vehicle for fixation, and the fixing plate is fixed to the bottom of the vehicle with bolts, and the threaded holes and the mounting holes are aligned to each other, so that it can be adapted to a variety of vehicles for use, thereby improving the applicability of the device; the utility model is that when the vehicle is bumpy and vibrating, the floating rod will push the hydraulic rod to move, the movable plate slides in the sliding groove, compresses the spring, and then under the action of the elastic force of the spring, the hydraulic rod controls the floating rod to reset, thereby achieving better shock absorption when passing through bumpy roads, thereby improving the buffering performance of the device.

[0004] This patented technology improves the buffering performance during use, but there are still some shortcomings during use. The movable parts of the shock absorber, such as the floating rod and oil seal, are easily eroded by external sand and soil, and suffer great wear and tear during long-term use. The service life of the shock absorber structure is reduced during long-term use of the motorcycle. Therefore, those skilled in the art provide an inverted shock absorber structure for motorcycles to solve the problems raised in the above background technology. Utility Model Content

[0005] 1. Technical solution

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is an inverted shock absorber structure for a motorcycle, comprising:

[0008] The shock absorber body includes a bottom plate and a top plate, a mounting tube and a plug rod located at the lower end of the top plate and the upper end of the bottom plate and plugged into each other, a sealing ring embedded in the opening of the mounting tube and slidably mounted with the plug rod, a piston located at the upper end of the plug rod and slidably mounted inside the mounting tube, and two sets of one-way oil valves located inside the piston in opposite directions of flow.

[0009] The protective structure comprises a threaded ring threadedly mounted on the outer wall of the bottom plate, a shielding sleeve fixed on the outer wall of the threaded ring and sleeved on the outer side of the spring, and the inner wall of the upper end is glued and mounted on the outer wall of the top plate;

[0010] as well as;

[0011] A pressure control structure comprises a connecting tube connected to the top plate and the mounting tube, and an adjusting tube installed through the connecting tube.

[0012] Furthermore, the upper end of the connecting tube and the lower end of the base plate are both provided with mounting heads;

[0013] Specifically, the mounting head is used for connecting the top plate and the connecting tube with the mounting structure.

[0014] Furthermore, the lower side of the top plate is provided with positioning cylinders distributed in a circular array and located outside the spring, and the upper side of the bottom plate is provided with positioning rods distributed in a circular array and located outside the spring, and the positioning rods are slidably inserted into the interior of the positioning cylinders;

[0015] Specifically, the positioning rod is slidably installed inside the positioning cylinder and is located outside the spring. When the shock absorber body is telescopically moved, the positioning rod moves longitudinally inside the positioning cylinder, thereby shielding the shielding sleeve during use to avoid being affected by the spring.

[0016] Furthermore, a limiting ring is provided on the upper side of the bottom plate, and the outer diameter of the limiting ring is larger than the inner diameter of the threaded ring;

[0017] Specifically, the limiting ring limits the threaded ring to prevent the threaded ring from being twisted too much and entering the outer side of the plug rod.

[0018] Furthermore, a second sealing ring is embedded and installed at the opening of the regulating cylinder, a second plug rod is slidably installed inside the second sealing ring, and a second piston is provided on the upper end of the second plug rod and is slidably installed inside the regulating cylinder;

[0019] Specifically, the second plug rod is slidably mounted inside the regulating cylinder via the second sealing ring, thereby driving the second piston to slide inside the regulating cylinder.

[0020] Furthermore, the second lower end of the plug rod is provided with a threaded sleeve threadedly mounted on the outer wall of the lower end of the adjusting cylinder;

[0021] Specifically, the threaded sleeve is threadedly mounted on the outer wall of the adjusting cylinder. When the threaded sleeve is rotated, the threaded sleeve engages with the outer wall of the adjusting cylinder, and the threaded sleeve is positioned after rotation.

[0022] 2. Beneficial effects

[0023] Compared with the prior art, the advantages of the present invention are:

[0024] The utility model has a plug rod and a mounting cylinder that are slidably connected and arranged inside the spring. When the spring contracts, the piston squeezes the hydraulic rod inside the mounting cylinder, and two one-way oil valves with opposite flow directions apply resistance to the flowing hydraulic oil, thereby applying a damping effect to the spring, thereby achieving shock absorption of the motorcycle during driving.

[0025] At the same time, a retractable shielding sleeve is sleeved on the outside of the mounting tube and the spring, shielding the plug rod and the sealing ring inside the shielding sleeve, intercepting sand and soil splashed from the outside, thereby protecting the moving parts and improving the service life of the motorcycle shock absorber structure.

[0026] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention.

[0040] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0041] Example 1

[0042] See also Figure 1-Figure 5 As shown, this embodiment is an inverted shock absorber structure for a motorcycle, comprising:

[0043] Shock absorber body 100 includes a bottom plate 102 and a top plate 103; a mounting tube 104 and a plug rod 108 located at the lower end of top plate 103 and the upper end of bottom plate 102 and interlocked with each other; a sealing ring 107 embedded in the opening of mounting tube 104 and slidably mounted with plug rod 108; a piston 105 located at the upper end of plug rod 108 and slidably mounted within mounting tube 104; and two sets of one-way oil valves 109 located within piston 105 in opposite directions of oil flow.

[0044] The protective structure 200 includes a threaded ring 201 threadedly mounted on the outer wall of the bottom plate 102, and a shielding sleeve 203 fixed to the outer wall of the threaded ring 201 and sleeved on the outside of the spring 106, with the inner wall of the upper end glued to the outer wall of the top plate 103;

[0045] The upper end of the connecting tube 301 and the lower end of the base plate 102 are both provided with mounting heads 101;

[0046] The lower side of the top plate 103 is provided with positioning cylinders 205 distributed in a circular array and located outside the spring 106. The upper side of the bottom plate 102 is provided with positioning rods 204 distributed in a circular array and located outside the spring 106. The positioning rods 204 are slidably inserted into the interior of the positioning cylinders 205.

[0047] A limit ring 202 is provided on the upper side of the bottom plate 102 , and the outer diameter of the limit ring 202 is larger than the inner diameter of the threaded ring 201 ;

[0048] Performing the use of the protective structure 200;

[0049] The mounting head 101 is installed at the motorcycle shock absorber mounting position. When the motorcycle is in use, the spring 106 is forced to shrink during bumps, and the plug rod 108 drives the piston 105 to slide inside the mounting cylinder 104. The hydraulic oil is damped when passing through the one-way oil valve 109, and the spring 106 is damped, thereby reducing the vibration of the support. When the plug rod 108 slides and the spring 106 shrinks, the positioning rod 204 is slidably installed inside the positioning cylinder 205, and the shielding sleeve 203 slides on the outside of the positioning rod 204 and the positioning cylinder 205 to shield the shock absorber body 100 during use. When the motorcycle is running, the external sand and soil are intercepted to prevent the plug rod 108, spring 106 and sealing ring 107 from being eroded by sand and soil, thereby ensuring the cleanliness of the outer wall of the plug rod 108, thereby reducing the wear of the sealing ring 107, and playing the effect of protecting the moving parts of the shock absorber body 100, and improving the service life of the shock absorber body 100.

[0050] Example 2

[0051] See also Figure 1-Figure 5 As shown, this embodiment is based on embodiment 1 and also includes:

[0052] as well as;

[0053] A pressure control structure 300, a connecting cylinder 301 connected to the top plate 103 and the mounting cylinder 104, and an adjusting cylinder 302 connected to the connecting cylinder 301;

[0054] A second sealing ring 305 is embedded in the opening of the regulating cylinder 302, a second plug rod 306 is slidably installed inside the sealing ring 305, and a second piston 303 is provided on the upper end of the plug rod 306 and is slidably installed inside the regulating cylinder 302;

[0055] The lower end of the second plug rod 306 is provided with a threaded sleeve 304 threadedly mounted on the outer wall of the lower end of the adjustment cylinder 302;

[0056] Using the pressure control structure 300;

[0057] The threaded sleeve 304 rotates on the outer wall of the adjusting cylinder 302, driving the plug rod 2 306 to move longitudinally, and then driving the piston 2 303 to move longitudinally inside the adjusting cylinder 302. The lifted piston 2 303 squeezes the inside of the adjusting cylinder 302. Because the adjusting cylinder 302 is connected to the mounting cylinder 104, the mounting cylinder 104 is pressurized, and the resistance of the piston 105 during movement is increased. When the piston 2 303 descends, the pressure inside the adjusting cylinder 302 decreases, and the resistance of the piston 2 303 during movement is reduced. By adjusting the resistance inside the mounting cylinder 104, the damping effect of the shock absorber body 100 is adjusted to adapt to the shock absorption requirements of different road sections. The flexibility of the shock absorber body 100 is improved during use.
