Carbon fiber bicycle shock absorbing handle

Abstract

This utility model discloses a carbon fiber bicycle shock absorber handlebar, belonging to the field of bicycle accessory technology. The shock absorber handlebar includes a handlebar bracket, a fixed bracket, and a shock-absorbing mechanism disposed inside the fixed bracket. The shock-absorbing mechanism includes a telescopic rod connected to the handlebar bracket, a shock-absorbing spring, a rotating block, and a reset assembly composed of a sliding block and a reset spring. When the telescopic rod is stretched or retracted under force, it not only compresses the shock-absorbing spring but also, in conjunction with the rotating block, pushes the sliding block to compress the reset spring, forming dual shock absorption. Furthermore, the handlebar bracket itself is a multi-layered composite structure consisting of an inner support layer, a carbon fiber layer, an elastic interlayer, and a wear-resistant layer. Through the synergistic effect of the aforementioned dual shock absorption and the composite handlebar, this utility model effectively solves the problems of existing shock absorber handlebars having a simple structure and poor cushioning effect, efficiently absorbing and cushioning road impacts, and significantly improving riding comfort and handling stability.

Description

Technical Field

[0001] This utility model relates to the field of bicycle parts technology, and in particular to a carbon fiber bicycle shock absorber handlebar. Background Technology

[0002] With people paying increasing attention to healthy and environmentally friendly travel, bicycles have become a widely used means of transportation and fitness. During cycling, especially on unpaved roads or roads with poor conditions, the bumps experienced by the wheels are transmitted to the rider through the frame and handlebars. Prolonged vibrations not only reduce riding comfort but also easily lead to fatigue and discomfort in the hands, arms, and even the neck and shoulders.

[0003] In pursuit of lighter weight and better handling, carbon fiber, with its lightweight and high strength, is increasingly being used in the manufacture of high-end bicycle handlebars. However, the inherent rigidity of carbon fiber limits its ability to filter out high-frequency, minute vibrations. This means that bumps from the road are transmitted more directly and clearly to the rider's hands, which in turn exacerbates hand fatigue.

[0004] While some shock-absorbing handlebars have emerged in the existing technology to alleviate vibrations, their structures are often relatively simple, such as simply filling the handlebar with an elastomer or using a single spring mechanism. These solutions have limited shock absorption travel and limited cushioning capabilities. When faced with continuous or large impacts, their energy absorption efficiency is low, easily resulting in ineffective shock absorption or bottoming out, failing to meet riders' higher demands for a smooth and comfortable riding experience.

[0005] Therefore, this utility model proposes a carbon fiber bicycle shock absorber handle to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of poor riding comfort caused by the simple shock absorption structure, limited cushioning capacity, and inability to effectively absorb continuous impacts under complex road conditions in the existing carbon fiber bicycle shock absorber handlebars, this utility model aims to provide a carbon fiber bicycle shock absorber handlebar with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a carbon fiber bicycle shock absorber handlebar, including a handlebar bracket and a fixing bracket; the shock absorber handlebar also includes a shock-absorbing mechanism.

[0008] The shock absorption mechanism is located inside the fixed bracket and connects the handlebar bracket to the fixed bracket. Its specific structure includes a telescopic rod, a shock absorption spring, a rotating block, and a reset assembly.

[0009] Furthermore, one end of the telescopic rod is connected to the handlebar bracket, and the other end is telescopically accommodated within the fixed bracket; a damping spring is sleeved on the outer periphery of the telescopic rod; a rotating block is pivotally connected to the telescopic rod; the reset assembly includes a sliding block slidably disposed inside the fixed bracket, and a reset spring compressed by the sliding block; the sliding block and the rotating block are combined through a transmission connection, so that when the telescopic rod is stretched or retracted under force, it can not only compress the damping spring, but also drive the rotating block to compress the reset spring by the sliding block, thus forming a dual damping system.

[0010] Preferably, the shock absorber also includes an auxiliary mechanism, which constitutes the body of the handlebar bracket. The handlebar bracket is a multi-layer composite structure, which, from the inside out, consists of a support layer that provides stable support, a carbon fiber layer covering the support layer, an elastic interlayer covering the carbon fiber layer, and a wear-resistant layer covering the elastic interlayer.

[0011] Preferably, the auxiliary mechanism further includes a grip, which is fitted onto the outside of the handlebar bracket, and the inner surface of the grip is in close contact with the wear-resistant layer of the handlebar bracket to form a complete gripping part.

[0012] Preferably, the rotating block is provided with a protruding structure for pushing the sliding block. The rotation of the rotating block drives the sliding block to reciprocate along its sliding direction through the protruding structure, thereby achieving a stable and reliable transmission connection between the two.

[0013] Preferably, the damping spring is disposed between the inner wall of the telescopic rod and the fixed bracket, with its two ends respectively abutting against the inner wall of the fixed bracket and the integrally formed annular flange on the telescopic rod, so as to achieve precise positioning of the damping spring.

[0014] Preferably, the reset spring is disposed between the sliding block and one side inner wall of the fixed bracket, with its two ends abutting against the end face of the sliding block and one side inner wall of the fixed bracket, respectively, so as to be stably compressed when the sliding block slides.

[0015] Preferably, the shock absorber also includes a plurality of screws, and the handlebar bracket and the fixed bracket are fixedly connected by the plurality of screws, which together define an internal space for accommodating the shock absorption mechanism.

[0016] Preferably, the shock absorber handle also includes a connecting post, which is fixedly connected to the fixing bracket by screws, and its function is to install the shock absorber handle as a whole onto the bicycle frame.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem of poor shock absorption effect caused by the single structure and limited buffering capacity of existing bicycle shock absorbers by setting up a dual shock absorption structure in which a telescopic rod, a shock-absorbing spring, a rotating block and a reset component work together. It achieves the effect of absorbing and buffering vibration energy twice, thereby significantly improving riding comfort and handling stability. 2. This utility model solves the problem that traditional handlebars are difficult to balance grip comfort and durability while ensuring structural strength by designing the handlebar bracket as a multi-layer composite structure consisting of a support layer, a carbon fiber layer, an elastic interlayer, and a wear-resistant layer. It achieves a comprehensive technical effect that integrates high strength, comfort, auxiliary shock absorption, and durability. 3. This utility model solves the problems of complex and low reliability of some external shock absorption structures by integrating the main components of the shock absorption mechanism into the fixed bracket and realizing modular assembly with the handlebar bracket. It achieves the technical effect of compact structure, stable and reliable operation and easy installation and maintenance. Attached Figure Description

Detailed Implementation

[0020] Example: Refer to Figures 1 to 4 This utility model provides a carbon fiber bicycle shock absorber handle, which aims to solve the problem of poor riding comfort caused by the single shock absorption structure and limited cushioning effect of existing carbon fiber bicycle handles.

[0021] like Figures 1 to 4As shown, the carbon fiber bicycle shock absorber includes a handlebar bracket 1 and a fixed bracket 2. The handlebar bracket 1 is connected to the fixed bracket 2 via a shock-absorbing mechanism 4 disposed inside it. The shock-absorbing mechanism 4 provides a cushioning effect when the handlebar bracket 1 is subjected to bumps and impacts. The shock-absorbing mechanism 4 is entirely disposed inside the fixed bracket 2. Specifically, the shock-absorbing mechanism 4 includes a telescopic rod 41, a shock-absorbing spring 42, a rotating block 43, and a reset assembly 44. One end of the telescopic rod 41 is connected to the handlebar bracket 1, and the other end is telescopically accommodated in the fixed bracket 2. When the handlebar bracket 1 is subjected to force, the telescopic rod 41 extends and retracts within the fixed bracket 2. The shock-absorbing spring 42 is sleeved on the outer periphery of the telescopic rod 41 and is compressed when the telescopic rod 41 is subjected to force, thereby providing the first layer of shock absorption. The rotating block 43 pivots... The device is attached to the telescopic rod 41 and rotates synchronously with the telescopic rod 41. The reset assembly 44 is disposed inside the fixed bracket 2. The reset assembly 44 includes a sliding block 441 slidably disposed inside the fixed bracket 2 and a reset spring 442 housed in the fixed bracket 2 and compressed by the sliding block 441. The sliding block 441 and the rotating block 43 form a transmission connection. When the rotating block 43 rotates, it pushes the sliding block 441 to slide. The sliding of the sliding block 441 compresses the reset spring 442. The compression deformation of the reset spring 442 provides a second shock absorption force, thereby achieving double shock absorption. When the vibration disappears, the elastic restoring force of the shock absorption spring 42 and the reset spring 442 jointly push the telescopic rod 41 and the sliding block 441 to reset.

[0022] Reference Figure 1 The auxiliary mechanism 5 includes a multi-layer structure constituting the handlebar bracket 1 and a grip 51 sleeved on the outside of the handlebar bracket 1. The handlebar bracket 1 is a multi-layer composite structure, which consists of the following layers from the inside out: a support layer 55 that provides stable support; a carbon fiber layer 54 covering the support layer 55, which utilizes its high strength properties to ensure that the handlebar bracket 1 is not easily deformed during use; an elastic interlayer 53 covering the carbon fiber layer 54, which is elastic and used to absorb the slight vibrations transmitted from the hand and provide a comfortable touch; and a wear-resistant layer 52 covering the elastic interlayer 53, which is used to resist the wear generated when in contact with the grip 51 and extend the service life of the handlebar bracket 1.

[0023] Meanwhile, the auxiliary mechanism 5 also includes a grip 51. In the assembled state, the grip 51 is fitted onto the outside of the handlebar bracket 1, and the inner surface of the grip 51 is in close contact with the wear-resistant layer 52 of the handlebar bracket 1. This multi-layered composite grip structure, consisting of a support layer 55, a carbon fiber layer 54, an elastic interlayer 53, a wear-resistant layer 52, and a grip 51, provides riders with a comfortable, stable, and durable grip experience and helps absorb some of the vibration energy from the hand.

[0024] The connection between the handlebar bracket 1 and the fixed bracket 2, as well as the fixation of the entire shock absorber to the bicycle frame, are achieved through multiple screws 3 and connecting posts 6. Specifically, multiple screws 3 fix the handlebar bracket 1 and the fixed bracket 2, together defining the internal space for accommodating the shock absorption mechanism 4. The connecting posts 6 are fixedly connected to the fixed bracket 2 through screws 3, and the connecting posts 6 are used to install the entire carbon fiber bicycle shock absorber to the bicycle frame.

[0025] Reference Figure 3 and Figure 4 The rotating block 43 is provided with a protruding structure for pushing the sliding block 441. The protruding structure acts on the sliding block 441 as the rotating block 43 rotates, thereby driving the sliding block 441 to reciprocate along its preset sliding direction. In order to accurately limit and effectively transmit force to the damping spring 42, the damping spring 42 is set between the telescopic rod 41 and the inner wall of the fixed bracket 2, with its two ends abutting against the inner wall of the fixed bracket 2 and the annular flange integrally formed on the telescopic rod 41, respectively. To ensure that the return spring 442 can be stably compressed and provide a reliable return force, the return spring 442 is disposed between the sliding block 441 and the inner wall of one side of the fixed bracket 2, with its two ends abutting against the end face of the sliding block 441 and the inner wall of one side of the fixed bracket 2, respectively. To ensure a secure assembly and easy installation of the entire device, multiple screws 3 are used to securely connect the handlebar bracket 1 and the fixed bracket 2, and together define the internal space for accommodating the shock absorption mechanism 4. At the same time, the connecting post 6 is also secured to the fixed bracket 2 by screws 3, and the connecting post 6 is used to install the entire shock absorber handlebar onto the bicycle frame.

[0026] The working principle is as follows: When a rider rides on a bumpy road, the force generated by the vibration of the handlebar bracket 1 is transmitted to the telescopic rod 41. Under the action of the force, the telescopic rod 41 compresses the shock-absorbing spring 42. The shock-absorbing spring 42 absorbs part of the vibration energy through its own elastic deformation. At the same time, the movement of the telescopic rod 41 drives the rotating block 43 to rotate. The rotation of the rotating block 43 pushes the sliding block 441 to slide inside the fixed bracket 2 and squeeze the return spring 442, so that the return spring 442 further absorbs the vibration energy. Through the synergistic effect of the shock-absorbing spring 42 and the return spring 442, the dual absorption and buffering of vibration energy is achieved.

[0027] Once the vibrations subside, the elastic restoring force of the damping spring 42 and the return spring 442 will jointly push the telescopic rod 41 and the sliding block 441 back to their initial positions, thus achieving a continuous and effective shock absorption effect. In addition, when the rider grips the handlebars 51, the force of the hand is transmitted to the elastic interlayer 53 through the wear-resistant layer 52. The deformation of the elastic interlayer 53 helps to disperse the force and absorb minor vibrations, while the carbon fiber layer 54 and the support layer 55 work together to maintain the shape and strength of the handlebar bracket 1, thereby providing the rider with a comfortable and stable grip experience.
