Lightweight shockproof bicycle front fork bracket

Abstract

This utility model provides a lightweight shock-absorbing bicycle fork bracket, belonging to the bicycle manufacturing field. It includes a bracket rod with two sets of connecting rods symmetrically bolted to its bottom. Each set of connecting rods has a damping component at its bottom to reduce bumps caused by road surfaces. Through the mounting holes, this device can be installed on a bicycle. When the bicycle wheel encounters a bumpy surface, the wheel experiences an upward impact force. This upward impact force causes the first damping rod to rotate upwards around its hinge point with the bottom of the connecting rod. Simultaneously, the second damping rod rotates around its hinge point with the side wall of the connecting rod, thus buffering the impact energy transmitted from the road surface and reducing discomfort to the rider caused by road bumps.

Description

Technical Field

[0001] This utility model relates to the field of bicycle manufacturing, and more specifically, to a lightweight shockproof bicycle front fork bracket. Background Technology

[0002] During cycling, road conditions are often varied, which requires bicycles to be more comfortable to ride. One standard for improving comfort is to reduce bumps.

[0003] A search revealed that Chinese patent CN218400860U discloses "a bicycle front fork with good shock absorption, relating to the field of industrial processing. This bicycle front fork with good shock absorption includes an upper bracket and a shock-absorbing frame installed below the upper bracket; the shock-absorbing frame is provided with a sliding column, and the sliding column is provided with a shock-absorbing spring. The shock-absorbing frame includes: a sliding ring slidably connected to the sliding column; two sets of connecting frames, the bottom of which is connected to the sliding ring, and a spring is provided inside the connecting frame; two sets of sliders, which are connected to the springs; a triangular block is disposed between the two sets of sliders; and two sets of slide rails, which are disposed on the surface of the triangular block. This bicycle front fork with good shock absorption, due to the spring inside the connecting frame, reduces the vertical movement of the triangular block by the left and right movement of the spring, thereby reducing bumps and achieving the corresponding shock absorption effect to meet the user's requirements." However, it still has the following drawbacks:

[0004] The linkage structure of the slider, triangular block, and slide rail in this device requires precise matching. The matching accuracy between the slider and slide rail needs to be adjusted regularly, such as by using a feeler gauge to check the gap. Otherwise, misalignment can easily lead to jamming or excessive wear, affecting the shock absorption effect. At the same time, the assembly of multiple components increases the difficulty and cost of maintenance.

[0005] Therefore, we made improvements and proposed a lightweight, shock-absorbing bicycle fork bracket. Utility Model Content

[0006] The purpose of this invention is to address the problems of complex structure and high maintenance cost in current applications.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0008] Lightweight shock-absorbing bicycle fork brackets to improve the above problems.

[0009] The specific details of this utility model are as follows:

[0010] The system includes a support rod, with two sets of connecting rods symmetrically bolted to the bottom of the support rod. The bottom of each set of connecting rods is equipped with a shock-absorbing component to reduce the bumps caused to the bicycle by the road surface. An absorption component is provided on the top of the support rod to absorb the uncomfortable impact force on the rider's arms caused by uneven road surface.

[0011] The shock-absorbing assembly includes a first buffer rod located at the bottom of the connecting rod. One end of the first buffer rod is hinged to the bottom of the connecting rod, and the other end of the first buffer rod is hinged to a mounting rod. The mounting rod has a mounting hole on its inner side, and the other end of the mounting rod is hinged to a second buffer rod. The other end of the second buffer rod is hinged to the side wall of the connecting rod.

[0012] As a preferred technical solution of this utility model, the absorption component includes a sleeve post fixedly connected to the top of the support rod, a spring fixedly disposed inside the sleeve post, the spring being located inside the sleeve post, a damper disposed above the spring, the damper being located inside the sleeve post, and the spring being sleeved on the outside of the damper.

[0013] As a preferred technical solution of this utility model, a retaining ring is fixedly connected to the outer side of both sets of connecting rods, and a semi-circular ring is fixedly connected to the top of the retaining ring, and a threaded hole is opened on the top of the semi-circular ring.

[0014] As a preferred technical solution of this utility model, a threading ring is fixedly provided on the side wall of the connecting rod, and the threading ring is also located on the outer wall of the second buffer column.

[0015] As a preferred technical solution of this utility model, the damper is fixedly connected to two sets of limiting strips on the outside, the two sets of limiting strips are symmetrically arranged, and the inner wall of the sleeve post is provided with two sets of grooves that are adapted to the limiting strips.

[0016] As a preferred technical solution of this utility model, a reflective strip is bolted to the side wall of the connecting rod, and the reflective strip is arc-shaped.

[0017] As a preferred embodiment of this invention, the mounting hole is elliptical, and the connecting rod is made of carbon fiber composite material.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] In the solution of this utility model:

[0020] 1. With the shock-absorbing components in place, this device can be installed on a bicycle through the mounting holes on the inside of the mounting rod. When the bicycle wheel encounters a bumpy road surface, the wheel is subjected to an upward impact force. This upward impact force causes the first buffer rod to rotate upward around its hinge point with the bottom of the connecting rod. At the same time, the second buffer rod will rotate around its hinge point with the side wall of the connecting rod to buffer the impact energy transmitted from the road surface, thereby reducing the discomfort caused to the rider by road bumps and effectively reducing riding fatigue.

[0021] 2. With the absorption components in place, the top of the damper is connected to the bicycle handlebars during use. When the bicycle is riding on an uneven road surface, the impact force first acts on the damper, causing the damper to move downwards. This puts pressure on the spring, causing the spring to compress and deform, thus reducing the impact force. After the road bumps are passed, the impact force disappears, and the spring gradually returns to its original shape due to its own elastic restoring force, preparing for the next possible impact. This allows the rider to experience a more stable control experience during riding and reduces arm fatigue. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0030] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0031] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] like Figure 1 As shown, this embodiment proposes a lightweight shockproof bicycle fork bracket, including a bracket rod 1. Two sets of connecting rods 2 are symmetrically bolted to the bottom of the bracket rod 1. Both sets of connecting rods 2 are provided with shock-absorbing components 3 at the bottom to reduce the bumps caused to the bicycle by the road surface. An absorption component 4 is provided above the bracket rod 1 to absorb the uncomfortable impact force on the rider's arms caused by uneven road surface.

[0034] like Figure 2 As shown, the shock absorption assembly 3 includes a first buffer rod 301 located at the bottom of the connecting rod 2. One end of the first buffer rod 301 is hinged to the bottom of the connecting rod 2, and the other end of the first buffer rod 301 is hinged to a mounting rod 302. A mounting hole 303 is provided on the inner side of the mounting rod 302. The device can be installed on a bicycle through the mounting hole 303 on the inner side of the mounting rod 302. A second buffer rod 304 is hinged to the other end of the mounting rod 302, and the other end of the second buffer rod 304 is hinged to the side wall of the connecting rod 2. In use, this device can be installed on a bicycle through the mounting hole 303 on the inner side of the mounting rod 302. When the bicycle wheel encounters a raised road surface, the wheel is subjected to an upward impact force. The upward impact force will cause the first buffer rod 301 to rotate upward around its hinge point with the bottom of the connecting rod 2. At the same time, the second buffer rod 304 will rotate around its hinge point with the side wall of the connecting rod 2 to buffer the impact energy transmitted from the road surface, thereby reducing the discomfort caused to the rider by road bumps and effectively reducing riding fatigue.

[0035] like Figure 3As shown, the absorbing component 4 includes a sleeve post 401 fixedly connected to the top of the support rod 1. A spring 402 is fixedly installed inside the sleeve post 401. A damper 403 is installed above the spring 402, also located inside the sleeve post 401. The spring 402 is sleeved on the outside of the damper 403. In use, the top of the damper 403 is connected to the bicycle handlebars. When the bicycle travels on an uneven road surface, the impact force first acts on the damper 403, causing it to move downwards. This puts pressure on the spring 402, causing it to compress and deform, thus mitigating the impact force. After the bump passes, the impact force disappears, and the spring 402 gradually returns to its original shape due to its elastic restoring force, preparing for the next possible impact. This allows the rider to experience a smoother ride and reduces arm fatigue.

[0036] like Figure 2 As shown, retaining rings 5 ​​are fixedly connected to the outer sides of both sets of connecting rods 2. A semi-circular ring 6 is fixedly connected to the top of the retaining ring 5, and a threaded hole 7 is opened on the top of the semi-circular ring 6. In use, the mudguard of the bicycle front wheel can be installed through the threaded hole 7 opened on the top of the semi-circular ring 6.

[0037] like Figure 1 As shown, a wire threading ring 8 is fixedly installed on the side wall of the connecting rod 2. The wire threading ring 8 is also located on the outer wall of the second buffer post. The brake cable of the bicycle can be threaded through the wire threading ring 8 to avoid the brake cable from getting tangled and to fix the brake cable.

[0038] like Figure 3 As shown, two sets of limiting strips 9 are fixedly connected to the outer side of the damper 403. The two sets of limiting strips 9 are symmetrically arranged, and the inner wall of the sleeve post 401 has two sets of grooves that are adapted to the limiting strips 9. The cooperation between the limiting strips 9 and the grooves ensures that the damper 403 will not shake or shift when subjected to impact force, thereby ensuring the stability of the handlebar position.

[0039] like Figure 2 As shown, a reflective strip 10 is bolted to the side wall of the connecting rod 2. The reflective strip 10 is arc-shaped. When riding at night or in low light conditions, the reflective strip 10 can reflect the light in the surrounding environment, ensuring that the rider can maintain high visibility in various environments and further ensuring riding safety.

[0040] like Figure 5 and Figure 6As shown, the mounting hole 303 is elliptical, and the connecting rod 2 is made of carbon fiber composite material. The elliptical mounting hole 303 can disperse stress through its special shape, avoiding damage to the mounting hole 303 or connecting parts due to excessive local stress. The carbon fiber composite connecting rod 2 reduces the overall weight of the bicycle and improves riding speed and efficiency.

[0041] Specifically, when using this lightweight shock-absorbing bicycle front fork bracket: ... Figure 2 As shown, the lightweight shock-absorbing bicycle fork bracket is installed on the corresponding position on the bicycle frame using appropriate bolts and other fasteners through the elliptical mounting hole 303 on the inner side of the mounting rod 302. When the bicycle wheel encounters a bumpy road surface, the wheel experiences an upward impact force. This upward impact force causes the first buffer rod 301 to rotate upward around its hinge point with the bottom of the connecting rod 2. Simultaneously, the second buffer rod 304 rotates around its hinge point with the side wall of the connecting rod 2 to buffer the impact energy transmitted from the road surface, thereby reducing the discomfort caused to the rider by road bumps and effectively reducing riding fatigue. Figure 3 As shown, the top of the damper 403 is connected to the handlebars of the bicycle. When the bicycle is riding on an uneven road surface, the impact force first acts on the damper 403, causing the damper 403 to move downwards. This puts pressure on the spring 402, causing the spring 402 to compress and deform, thereby reducing the impact force and allowing the rider to experience a more stable control experience during riding, reducing arm fatigue.

[0042] All technical features in this embodiment can be freely combined according to actual needs.

[0043] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
