Description

Technical Field

[0001] This utility model relates to the field of bicycle technology, and in particular to a high-efficiency heat dissipation bicycle shock-absorbing front fork. Background Technology

[0002] With the continuous development of cycling, especially the increasing popularity of mountain biking and downhill biking, which require high shock absorption performance, riders have placed higher demands on the performance and reliability of suspension forks. During long-term, high-intensity riding, efficient heat dissipation has become one of the key factors in ensuring the stable operation of suspension forks and extending their service life. Therefore, developing a bicycle suspension fork with efficient heat dissipation is of great significance for improving the overall performance of bicycles and the riding experience. Traditional bicycle suspension forks are usually made of aluminum alloy. Although these materials have a certain strength and durability, their heat dissipation performance is relatively poor, making it difficult to dissipate heat quickly and effectively. Existing suspension forks mainly focus on shock absorption function and strength in their structural design, with relatively little consideration for heat dissipation.

[0003] During cycling, uneven road surfaces generate various vibrations and impacts. A shock absorption system can effectively absorb these vibrations, reducing the impact force transmitted to the rider's body, thereby reducing rider fatigue after long rides and making cycling more comfortable. A good shock absorption system allows the bicycle wheels to better contact the ground when encountering obstacles or uneven road surfaces, maintaining good contact and sufficient grip between the tires and the ground, thus ensuring the bicycle's handling stability. Riders can more accurately control the bicycle's steering, braking, and acceleration, reducing the probability of slipping or losing control in complex road conditions. Without shock absorption, on bumpy roads, the transmission components will be subjected to greater impact forces due to the lack of cushioning from the shock-absorbing fork, which can easily lead to problems such as chain slippage, sprocket deformation, and accelerated wear of the freewheel. This results in a decrease in the stability and efficiency of the transmission system, and may even lead to transmission failure, making it impossible to continue riding. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-efficiency heat dissipation bicycle shock-absorbing front fork, which aims to improve the problem in the prior art that if a bicycle cannot be shock-absorbing, the stability and efficiency of the transmission system will decrease, and even transmission failure may occur, making it impossible to continue riding.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a high-efficiency heat dissipation bicycle shock-absorbing fork, including a fork barrel, a stroke tube slidably connected to the top of the inner wall of the fork barrel, fork legs fixedly connected to the bottom front side of the fork barrel, a plurality of fork legs slidably connected to adjacent fixed posts, limit rings threadedly connected to the left and right sides of the outer wall of the fixed posts, a sliding ring fixedly connected to the middle of the outer wall of the stroke tube, a first fixed ring fixedly connected to the inner wall of the fork barrel, a spring fixedly connected to the top of the first fixed ring, a damping block provided at the bottom of the inner wall of the fork barrel, and a heat dissipation mechanism provided on the outer wall of the fork barrel, the heat dissipation mechanism being used to dissipate heat from the device.

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

[0007] The heat dissipation mechanism includes a heat sink, the inner wall of which is fixedly connected to the outer wall of the fork barrel. A screw is threaded onto both the upper and lower sides of the outer wall of the heat sink. A connecting ring is fixedly connected to the top of the heat sink. A lubrication ring is fixedly connected to the top of the fork barrel. A stop is fixedly connected to the top of the lubrication ring. A connecting block is fixedly connected to the outer wall of the stop.

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

[0009] The top end of the travel tube is slidably connected to a collar, and the rear side of the bottom end of the outer wall of the fork barrel is fixedly connected to a disc brake mounting bracket.

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

[0011] The top of the collar is threaded with a screw, and the bottom of the outer wall of the screw is threaded to the inner wall of the top of the travel tube.

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

[0013] A washer is slidably connected to the top of the outer wall of the screw two, and a mark is fixedly connected to the bottom of the outer wall of the fork barrel.

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

[0015] The left side of the collar is fixedly connected to a fork shoulder, and the top of the fork shoulder is fixedly connected to an upper tube.

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

[0017] A second fixing ring is fixedly connected to the top of the outer wall of the fork barrel, and a fork bridge is fixedly connected to the front side of the second fixing ring.

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

[0019] The outer right side of the screw is threadedly connected to the outer left side of the fork barrel, and the outer wall of the lubrication ring is fixedly connected to the inner wall of the connecting block.

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

[0021] 1. In this utility model, when the bicycle is riding on a steep slope, the body vibrates, the stroke tube and the sliding ring move downwards, compressing the spring. The spring deforms under the action of the damping block to generate elastic force, which cancels out part of the vibration. The excess vibration is eliminated by the damping block, thus realizing the shock absorption of the bicycle and preventing the bicycle from becoming unstable due to the steep road surface, which would affect the service life of the entire bicycle.

[0022] 2. In this utility model, the friction between the stroke tube and the fork barrel causes the temperature of the fork barrel to rise. Therefore, heat sinks are installed on the outer wall of the fork barrel to dissipate heat. At the same time, a lubricating ring lubricates the outer wall of the stroke tube to reduce friction, and a stop block prevents dust particles from entering the interior of the fork barrel and increasing friction. This achieves efficient heat dissipation for the bicycle and reduces friction, which not only prevents heat generation but also protects the inner wall of the fork barrel.

The outer wall of the lubrication ring 204 is fixedly connected to the inner wall of the connecting block 206.

[0034] Specifically, the heat sink 201 is fixedly connected to the fork 1, ensuring effective heat conduction and dissipation. The heat sink 201 is threadedly connected to screw 203, which is not only stable but also easy to disassemble and maintain. The heat sink 201 is fixedly connected to the connecting ring 202, which plays a fixing role. The lubricating ring 204 aims to reduce friction of the fork 1 during operation and extend its service life.

[0035] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 The top end of the stroke tube 3 is slidably connected to a collar 11, and the rear side of the bottom end of the outer wall of the fork bucket 1 is fixedly connected to a disc brake mounting seat 19. The top end of the collar 11 is threadedly connected to a screw 12, and the bottom end of the outer wall of the screw 12 is threadedly connected to the inner wall of the top end of the stroke tube 3.

[0036] Specifically, the stroke tube 3 and the collar 11 are slidably connected, ensuring flexible interaction between the two. The fork hopper 1 is fixedly connected to the disc brake mounting bracket 19, which is not only stable but also provides a solid foundation for the installation of the disc brake system. The screw 12 is threadedly connected to the stroke tube 3, which not only ensures the reliability of the braking system but also provides convenience for maintenance and adjustment.

[0037] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 3 The left side of the collar 11 is fixedly connected to the shoulder 13, the top of the shoulder 13 is fixedly connected to the upper tube 14, the top of the outer wall of the screw 12 is slidably connected to the washer 18, and the bottom of the outer wall of the fork bucket 1 is fixedly connected to the mark 17.

[0038] Specifically, the collar 11 is fixedly connected to the fork shoulder 13, ensuring the stability of the entire structure; the fork shoulder 13 is fixedly connected to the upper tube 14, enhancing the load-bearing capacity of the device; the screw 12 is slidably connected to the washer 18, allowing for minor adjustments to adapt to different working environments; and the fork bucket 1 is fixedly connected to the marking 17, providing the operator with necessary information.

[0039] Working principle: When the bicycle is traveling on a steep road, the bicycle body will vibrate. The vibration of the bicycle body will cause the stroke tube 3 to move downward. The stroke tube 3 will drive the sliding ring 7 to move downward together. The sliding ring 7 will squeeze the spring 8. The spring 8 will deform and generate elastic force under the action of the damping block 10. The elastic force can offset part of the vibration. The excess vibration will be eliminated by the damping block 10, which can realize the shock absorption of the bicycle and prevent the bicycle body from becoming unstable due to the steep road surface, thus affecting the service life of the entire bicycle body.

[0040] Because the friction between the stroke tube 3 and the inside of the fork barrel 1 causes the internal temperature of the fork barrel 1 to be high, a heat sink 201 is installed on the outer wall of the fork barrel 1. The heat sink 201 can absorb the heat inside the fork barrel 1 and dissipate it into the air. The lubrication ring 204 can lubricate the outer wall of the stroke tube 3, thereby reducing friction. The stop block 205 is to prevent external dust particles from entering the interior of the fork barrel 1 and increasing friction. This achieves efficient heat dissipation for the bicycle and reduces friction, which not only prevents heat generation but also protects the inner wall of the fork barrel 1.

[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. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
