Description

Technical Field

[0001] This utility model relates to the field of shock absorber technology, specifically a damping adaptive shock absorber. Background Technology

[0002] For riding comfort, motorcycles are equipped with shock absorbers. However, the required elasticity of the shock absorbers varies depending on the road conditions and the type of motorcycle. Spring preload, simply put, is how much the spring is compressed beforehand. This determines whether the spring is stiff or soft. If the shock absorber is too soft, the motorcycle will bounce up and down. If the shock absorber is too stiff, it will create too much resistance and hinder the normal operation of the spring. Therefore, the rider can adjust the spring preload according to the road conditions and their own comfort level.

[0003] A search revealed a Chinese patent publication number: CN223227758U, which provides an adaptive electro-hydraulic adjustable spring preload shock absorber, comprising: a shock absorption mechanism, a lifting component, and an adjustment mechanism. The shock absorption mechanism includes a cylinder, a main shaft, an external thread, a support seat, a baffle, a spring, and a damping adjustment cylinder. The main shaft is located at the top of the cylinder, the external thread is located at the lower end of the outer wall of the cylinder, the support seat is located at the lower end of the external thread, the baffle is located at the top of the main shaft, and the spring is located at the bottom of the baffle.

[0004] Although the aforementioned patent allows for adjustment of the spring's support height, the aforementioned worm gear still has the following problems: Existing shock absorbers achieve lifting and lowering by controlling the worm gear transmission through an adjustment mechanism. However, the meshing parts of the worm gear are prone to wear due to friction during frequent adjustments, which may lead to increased adjustment torque, jamming, or even failure, seriously affecting service life and user experience, and making it difficult to meet the needs of long-term high-frequency adjustment. In view of the above situation, technological innovation is carried out on the basis of the existing device. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This damping adaptive shock absorber, through the cooperation of the base plate and the oil outlet pipe, enables the worm gear to be lubricated during rotation. The oil drips at the meshing point of the worm gear and worm, forming an oil film between the tooth surfaces, reducing the friction coefficient of direct contact, reducing abrasive wear and adhesive wear between metals, significantly extending the service life of the worm gear and worm, and avoiding component failure caused by long-term adjustment. At the same time, lubrication can reduce the friction at the meshing point, making operation easier.

[0016] 2. This damping adaptive shock absorber, through the cooperation of the bottom shell and the top block shell, can effectively block impurities from entering the meshing gap of the worm gear, avoiding the aggravation of tooth surface wear, transmission jamming or lubrication layer contamination caused by the accumulation of particulate matter, thereby ensuring the transmission accuracy and smoothness of the worm gear, while protecting the structural integrity of the worm gear and avoiding adjustment failure or functional abnormality caused by mechanical damage.

[0025] Please see Figures 1-7 The present invention provides a technical solution: a damping adaptive shock absorber, including a shock absorber body 1. The shock absorber body 1 is an existing structure, which will not be described in detail here. A worm gear 7 is provided on the surface of the shock absorber body 1. A bottom shell 2 is rotatably connected to the surface of the worm gear 7. A top shell 3 is fixedly installed on the top of the bottom shell 2 by bolts. A worm 8 is rotatably connected inside the bottom shell 2. The surfaces of the worm gear 7 and the worm 8 are meshed and connected. Both the worm gear 7 and the worm 8 are existing structures, which will not be described in detail here.

[0026] In the above embodiments, the connection method between the shock absorber body 1 and the worm gear 7 is the same as that of the prior art with publication number CN223227758U. Since it is a conventional technical means in this field, it will not be described in detail here.

[0027] The top shell 3 has an oil storage chamber 9 inside. An oil injection pipe 5 is fixedly connected to the top of the top shell 3. The inside of the oil injection pipe 5 is connected to the inside of the oil storage chamber 9. A cover 6 is threadedly connected to the top of the oil injection pipe 5. An oil outlet pipe 17 is provided inside the top shell 3. The inside of the oil outlet pipe 17 is connected to the inside of the oil storage chamber 9. The bottom of the oil outlet pipe 17 is above the meshing point of the worm gear 7 and the worm 8. By twisting, the cover 6 is removed. Then, lubricating oil is injected into the oil storage chamber 9 through the oil injection pipe 5 and falls through the oil outlet pipe 17. The lubricating oil dripping from the oil outlet pipe 17 can fall exactly at the meshing point of the worm gear 7 and the worm 8 to lubricate it.

[0028] The top shell 3 has a sliding groove 14 inside, and a slider 13 is slidably connected inside the sliding groove 14. A connecting rod 15 is fixedly connected inside the sliding groove 14, and the surface of the connecting rod 15 is slidably connected to the inside of the slider 13. A spring 16 is fixedly connected inside the sliding groove 14, and the side of the spring 16 near the slider 13 is fixedly connected to the surface of the slider 13. The spring 16 is sleeved on the surface of the connecting rod 15. By sliding the slider 13, the slider 13 can compress and reset the spring 16.

[0029] A base plate 11 is fixedly connected to the bottom of the slider 13. The top of the base plate 11 can block the outlet of the bottom of the oil pipe 17 to prevent the lubricating oil inside from dripping. A triangular block 12 is fixedly connected to the bottom of the base plate 11, and a fixed rod 10 is fixedly connected to the top of the worm gear 7. With the rotation of the worm gear 7, because the triangular block 12 is triangular in shape, the fixed rod 10 makes a circular motion on the top of the worm gear 7, so that the fixed rod 10 squeezes the triangular block 12 and causes the fixed rod 10 to drive the slider 13 on the top of the base plate 11 to slide inside the slide groove 14 and squeeze the spring 16. At the same time, the base plate 11 slides out of the outlet position of the bottom of the oil pipe 17, so that the lubricating oil inside the oil pipe 17 can drip down. When the fixed rod 10 slides out of the surface of the triangular block 12, the spring force of the spring 16 causes the slider 13 to return to its original position and drives the base plate 11 to re-seal the outlet of the oil pipe 17.

[0030] The top shell 3 has a transmission groove 19 inside, and a threaded rod 20 is rotatably connected inside the transmission groove 19. An outer frame 21 is slidably connected inside the transmission groove 19, and the inside of the outer frame 21 is threadedly connected to the surface of the threaded rod 20. The top shell 3 has a baffle groove 18 inside, and the inside of the baffle groove 18 is interconnected with the inside of the transmission groove 19. A baffle block 22 is slidably connected inside the baffle groove 18, and one side of the baffle block 22 is fixedly connected to one side of the outer frame 21. A rotating handle 4 is rotatably connected to the surface of the top shell 3, and one end of the rotating handle 4 is fixedly connected to one end of the threaded rod 20. By rotating the rotating handle 4, the threaded rod 20 drives the outer frame 21 to slide inside the transmission groove 19, and drives the baffle block 22 on one side to slide inside the baffle groove 18, so that the baffle groove 18 will not block the oil outlet pipe 17, and the oil outlet pipe 17 can drip lubricating oil again.

[0031] Working principle: For this type of damping adaptive shock absorber, when the support height needs to be adjusted, first turn the handle 4 to rotate the threaded rod 20, causing the outer frame 21 to slide inside the transmission groove 19, and causing the stop block 22 on one side to slide inside the stop groove 18, preventing the stop block 22 from blocking the oil outlet pipe 17. At the same time, when the worm 8 drives the worm wheel 7 to rotate, because the triangular block 12 is triangular in shape, the fixing rod 10 makes a circular motion on the top of the worm wheel 7, causing the fixing rod 10 to squeeze the triangular block 12, and causing the fixing rod 10 to drive the slider 13 on the top of the base plate 11 to slide inside the slide groove 14. The spring 16 is compressed, and the base plate 11 slides out of the outlet position of the oil pipe 17, so that the lubricating oil inside the oil pipe 17 can drip onto the meshing point of the worm gear 7 and the worm 8 to lubricate it and prevent wear. At the same time, when the fixed rod 10 slides out of the surface of the triangular block 12, the spring force of the spring 16 causes the slider 13 to return to the original position and drives the base plate 11 to re-seal the outlet of the oil pipe 17. After the height adjustment is completed, the handle 4 needs to be turned again so that the outer frame 21 drives the stop block 22 to re-seal the oil pipe 17 to prevent the base plate 11 from releasing the seal on the oil pipe 17 during vibration.
