Description

Technical Field

[0001] This utility model relates to the field of bicycle technology, and in particular to a bicycle suspension fork with a replaceable damping core. Background Technology

[0002] With the development of mountain biking, riding scenarios are becoming increasingly diverse, and the performance requirements for bicycle suspension forks are also getting higher and higher. Riders need to precisely adjust the damping characteristics of the suspension fork according to different riding scenarios and personal preferences in order to obtain the best shock absorption effect and handling performance. Different riders have different weights, riding styles and skill levels, and their damping needs for suspension forks are also different. The design of replaceable damping cores allows riders to choose the most suitable damping core according to their specific situation, realize personalized shock absorption adjustment, and improve riding comfort and efficiency.

[0003] Different riding scenarios place vastly different demands on the damping of suspension forks. In off-road riding, stiffer damping is needed to handle large impacts and rough terrain, preventing the fork from compressing excessively and losing control. On flat roads, softer damping is required to provide better comfort. Replacing the damping core allows for adjustments to the fork's damping characteristics based on specific road conditions, making riding more comfortable and safer. If the damping core cannot be replaced, the suspension fork will not be able to provide adequate cushioning for different road conditions, causing the rider to experience more bumps and vibrations during the ride, leading to fatigue after long rides and reduced riding comfort. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a bicycle suspension fork with a replaceable damping core, which aims to improve the problem in the prior art where the inability to replace the damping core leads to the suspension fork being unable to provide appropriate cushioning according to different road conditions.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a replaceable damping core bicycle suspension fork, including a fork barrel, a stroke tube slidably connected to the inner wall of the fork barrel, a fork leg fixedly connected to the front side of the bottom end of the outer wall of the fork barrel, a fixing ring fixedly connected to the front side of the fork leg, a connecting post slidably connected to the inner wall of the fixing ring, a stop block fixedly connected to the outer wall of the stroke tube, a spring fixedly connected to the bottom end of the stop block, a second fixing block fixedly connected to the top end of the fork barrel, a damping block slidably connected to the bottom end of the inner wall of the fork barrel, and a disassembly mechanism provided on the outer wall of the fork barrel for disassembling and replacing the damping block.

[0006] As a further description of the above technical solution:

[0007] The disassembly mechanism includes a support ring, the outer wall of which is slidably connected to the inner wall of the fork barrel, a screw threadedly connected to the middle of the outer wall of the fork barrel, a fixing block fixedly connected to the inner wall of the stroke tube, fixing posts fixedly connected to the left and right sides of the outer wall of the fixing block, a sleeve slidably connected to the top of the stroke tube, and a screw threadedly connected to the top of the sleeve.

[0008] As a further description of the above technical solution:

[0009] A lubricating ring is fixedly connected to the top of the second fixed block, and the inner wall of the lubricating ring is slidably connected to the outer wall of the travel tube.

[0010] As a further description of the above technical solution:

[0011] A disc brake mounting bracket is fixedly connected to the rear side of the bottom of the outer wall of the fork barrel, and limit rings are threaded to the left and right sides of the outer wall of the connecting column.

[0012] As a further description of the above technical solution:

[0013] The outer wall of the sleeve is fixedly connected to a fork shoulder, and the top of the fork shoulder is fixedly connected to an upper tube.

[0014] As a further description of the above technical solution:

[0015] The outer wall of the fixed block 2 is fixedly connected to a fork bridge, and the outer wall of the fork barrel is fixedly connected to a marking.

[0016] As a further description of the above technical solution:

[0017] The outer wall of the second screw is slidably connected with a washer, and the bottom end of the outer wall of the second screw is threadedly connected to the inner wall of the travel tube.

[0018] As a further description of the above technical solution:

[0019] The inner wall of the spring is slidably connected to the outer wall of the travel tube, and the top end of the outer wall of the travel tube is slidably connected to the inner wall of the second fixing block.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when the bicycle is traveling on a bumpy road, the connecting column and the fixing ring bear an upward thrust, which causes the stroke tube to be squeezed downward. The movement of the stroke tube drives the stop block downward, thereby compressing the spring. The spring deforms under the action of the support ring to generate elastic force to buffer the thrust. If the thrust is too large, the damping block will further absorb the impact, thus realizing shock absorption for the bicycle and preventing excessive vibration from damaging some structures and seriously affecting the user's use.

[0022] 2. In this utility model, when disassembling the equipment, screw one is turned to make it turn out of the fork bucket, the support ring loses its support, and then the stroke tube is pulled out. It will drive the fixed block one and the fixed column to move upward. Since the support ring is no longer fixed by screw one, it will move upward with the stroke tube and be pulled out, thereby releasing the damping block. This realizes the replacement and maintenance of the damping block, preventing the shock absorption effect from decreasing due to prolonged use and affecting the service life of the equipment.

[0034] Specifically, the support ring 201 is slidably connected to the fork 1, ensuring smooth movement and stable support between the two. The fork 1 is threadedly connected to the screw 202, which not only enhances the structural rigidity but also facilitates later maintenance and replacement.

The stroke tube 3 is slidably connected to the fixed block 2 9, which makes the entire mechanical device more flexible in operation, while maintaining a high degree of accuracy and stability.

[0039] Working principle: When the bicycle is traveling on a bumpy road, the connecting column 6 and the fixing ring 5 will be pushed upward, which will cause the stroke tube 3 to be squeezed downward. The compression of the stroke tube 3 will drive the stop block 7 to move downward together. The stop block 7 will squeeze the spring 8, which will deform under the action of the support ring 201 and generate elastic force to buffer the push force. If the push force is large, it will squeeze the damping block 10, which will further buffer the push force, thus realizing the shock absorption of the bicycle and preventing excessive vibration from damaging some structures and seriously affecting the user's use.

[0040] To disassemble the equipment, turn screw 202 to remove it from the inside of the fork bucket 1, causing the support ring 201 to lose its support. Then, pull out the stroke tube 3. The stroke tube 3 will move the lower fixing block 203 and the fixing column 204 upward together. The fixing column 204 will then support the support ring 201. Since the support ring 201 is no longer fixed by screw 202, it will move upward and be pulled out, thus releasing the damping block 10. This allows for the replacement and maintenance of the damping block 10, preventing the damping effect from decreasing due to prolonged use and affecting the service life of the equipment.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
