Description

Technical Field

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

[0002] An efficient bicycle fork damping mechanism is an important device for improving the cycling experience. During riding, when encountering bumpy roads, this mechanism can effectively absorb vibrations and reduce the impact on the rider. Through reasonable design, it can quickly respond to changes in road conditions, provide a smooth riding experience, and improve riding comfort and safety.

[0003] When a bicycle travels on an uneven surface, the front fork is subjected to impact forces from the ground. The spring is compressed and absorbs some of the impact force through its own elastic deformation, thus playing a buffering role. Through internal fluid or mechanical structures, the kinetic energy is converted into other forms of energy and dissipated, making the movement of the front fork more stable and providing the rider with a comfortable riding experience.

[0004] In existing high-efficiency bicycle fork damping mechanisms, the springs compress and rebound rapidly when encountering bumps, causing the fork to bounce violently and vibrate frequently and significantly. This makes it difficult for the rider to control the direction, greatly reducing riding stability and safety, and failing to provide the rider with a smooth riding experience. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a high-efficiency bicycle front fork buffer mechanism, which aims to improve the problem that when encountering bumps, the spring will compress and rebound quickly, which reduces the safety of riding.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a high-efficiency bicycle front fork buffer mechanism, comprising a main rod and a protective mechanism. A fork shoulder is fixedly connected to the bottom wall of the main rod. Fixing rings are fixedly connected to the left and right sides of the fork shoulder. Screws are threaded onto the front sides of both fixing rings. A first-stage travel tube is fixedly connected to the inner wall of each of the two first-stage travel tubes. Two fixing plates are fixedly connected to the bottom walls of the adjacent fixing plates. Springs are fixedly connected around the perimeter of the bottom walls of the multiple fixing plates. Support plates are fixedly connected to the bottom walls of the multiple fixing plates. Dampers are fixedly connected between adjacent support plates. A second-stage travel tube is fixedly connected to the bottom end of the two fixing plates. A protective mechanism is provided on the bottom wall of the two first-stage travel tubes. The protective mechanism is used to protect the buffer device.

[0007] As a further description of the above technical solution:

[0008] The protective mechanism includes a protective sleeve. The outer wall of the protective sleeve is set on the inner wall of the first and second travel tubes. A semi-circular groove is formed around the outer wall of the protective sleeve. A semi-circular groove is formed around the inner wall of the first and second travel tubes. A rotating ball is slidably connected to the inner wall of the semi-circular groove. A fixing ring is fixedly connected to the bottom end of the first travel tube and the top end of the second travel tube.

[0009] As a further description of the above technical solution:

[0010] A reflector is fixedly connected to the middle of the outer wall of each of the two travel tubes, and a reflective strip is fixedly connected to the outer wall of each of the two reflectors.

[0011] As a further description of the above technical solution:

[0012] A connecting plate is fixedly connected to the middle of the front side of the outer wall of the main rod, and a ring is fixedly connected to the front side of the connecting plate.

[0013] As a further description of the above technical solution:

[0014] A lamp holder is fixedly connected to the middle of the front side of the fork shoulder, and a lighting lamp is fixedly connected to the front side of the lamp holder.

[0015] As a further description of the above technical solution:

[0022] 1. In this utility model, when subjected to impact, the springs are first compressed, and these springs will deform, which can absorb part of the impact force. The dampers between multiple adjacent support plates work together with the springs, so that the dampers can slow down the transmission speed of the impact force through their own damping characteristics, further consume energy, thereby increasing the stability and safety of riding.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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 protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a high-efficiency bicycle front fork buffer mechanism, including a main rod 1, a fork shoulder 3 fixedly connected to the bottom wall of the main rod 1, a fixing ring 4 fixedly connected to the left and right sides of the fork shoulder 3, a screw 5 threadedly connected to the front side of the two fixing rings 4, a travel tube 6 fixedly connected to the inner wall of the two fixing rings 4, two fixing plates 7 fixedly connected to the bottom wall of the two travel tubes 6, springs 8 fixedly connected to the bottom walls of the adjacent fixing plates 7, support plates 9 fixedly connected to the bottom walls of the multiple fixing plates 7, dampers 10 fixedly connected to the adjacent support plates 9, and a travel tube 11 fixedly connected to the bottom end of the two fixing plates 7. When subjected to impact, shock absorption and buffering are achieved through the springs 8 between the two fixing plates 7 and the dampers 10 between the two support plates 9, thereby effectively reducing the impact force during riding. A protection mechanism 2 is provided on the bottom wall of the two travel tubes 6 to protect the buffer device.

[0033] Specifically, the bottom wall of the main rod 1 is firmly connected to the fork shoulder 3. The fixing rings 4 on both sides of the fork shoulder 3 play an important role. The screws 5 on the front side of the fixing rings 4 can securely connect them. The stroke tube 6 on the inner wall of the two fixing rings 4 provides support for the subsequent structure. Between the two fixing plates 7 on the bottom wall, multiple springs 8 are evenly distributed around the perimeter. When impacted, these springs 8 will deform and absorb part of the impact force. At the same time, the dampers 10 between the adjacent support plates 9 will also play a role. They work together with the springs 8. When the impact force is transmitted, the springs 8 first compress and absorb part of the energy, while the dampers 10 slow down the transmission speed of the impact force through their own damping characteristics, further dissipating the energy. The stroke tube 11 also provides auxiliary support, which can effectively reduce the impact force from the ground, provide a more comfortable experience for the rider, and protect the rider's body from excessive impact.

A fixing ring 205 is fixedly connected to the bottom end of the stroke tube 1 and the top end of the stroke tube 2 11. When impacted, the ball bearing 204 between the stroke tube 1 and the stroke tube 2 11 rotates between the semi-circular groove 1 202 and the semi-circular groove 2 203. The fixing ring 205 can block the ball bearing 204 from rotating out.

[0035] Specifically, the outer wall of the protective sleeve 201 is placed on the inner wall of the first stroke tube 6 and the second stroke tube 11. The outer wall of the protective sleeve 201 is provided with a semi-circular groove 202 around its perimeter.

When impacted, the rotating ball 204 will rotate flexibly between the semi-circular groove 202 and the semi-circular groove 203. The fixing ring 205 fixed at the bottom end of the first stroke tube 6 and the upper end of the second stroke tube 11 plays a key role. They can effectively prevent the rotating ball 204 from rotating out. The rotation of the rotating ball 204 can help buffer the impact force, reduce the direct friction and collision between the first stroke tube 6 and the second stroke tube 11, and improve the stability and durability of the entire structure.

The connecting plate 14 on the middle of the front side of the outer wall of the main rod 1 is connected to a ring 15. The ring 15 can be used to hang cables and conveniently hang some items. The lamp holder 16 on the middle of the front side of the fork shoulder 3 is fixed with a light 17, which can provide illumination in dark environments, making it easier for riders to see the road and improving riding safety.

[0039] Specifically, the two travel tubes 6 are connected to the loading box 19 by a connecting rod 18. The loading box 19 can be used to place objects to meet the rider's loading needs. The cover 20 on its top wall plays a protective role. The handle 21 on the middle of the rear side of the top wall of the cover 20 makes it easy to open the cover 20. In addition, the two hinges 22 on the front top of the loading box 19 are connected to the front side of the cover 20, so that the cover 20 can be opened and closed flexibly. Through the cooperation of the handle 21 and the hinges 22, the cover 20 can be easily opened or closed, making it convenient to put in and take out items.

[0040] Working principle: The bottom wall of the main rod 1 is firmly connected to the fork shoulder 3. The fixing rings 4 on both sides of the fork shoulder 3 play an important role. The screws 5 on the front side of the fixing rings 4 can securely connect them. The stroke tube 6 on the inner wall of the two fixing rings 4 provides support for the subsequent structure. Between the two fixing plates 7 on the bottom wall, multiple springs 8 are evenly distributed around the perimeter. When impacted, these springs 8 will deform and absorb part of the impact force. At the same time, the dampers 10 between the adjacent support plates 9 will also play a role. They work together with the springs 8. When the impact force is transmitted, the springs 8 first compress and absorb part of the energy, while the dampers 10 slow down the transmission speed of the impact force through their own damping characteristics, further dissipating the energy. The stroke tube 11 also provides auxiliary support, which can effectively reduce the impact force from the ground, provide a more comfortable experience for the rider, and protect the rider's body from excessive impact.

[0041] Furthermore, the outer wall of the protective sleeve 201 is placed on the inner wall of the first stroke tube 6 and the second stroke tube 11. The outer wall of the protective sleeve 201 is provided with a semi-circular groove 202 around its perimeter, and the inner walls of the first stroke tube 6 and the second stroke tube 11 are provided with a semi-circular groove 203 around their perimeter. The rotating ball 204 is slidably connected to the inner wall of the semi-circular groove 202. When impacted, the rotating ball 204 will rotate flexibly between the semi-circular groove 202 and the semi-circular groove 203. The fixing ring 205 fixed at the bottom end of the first stroke tube 6 and the upper end of the second stroke tube 11 plays a key role. They can effectively prevent the rotating ball 204 from rotating out. The rotation of the rotating ball 204 can help buffer the impact force, reduce the direct friction and collision between the first stroke tube 6 and the second stroke tube 11, and improve the stability and durability of the entire structure.
