Description

Technical Field

[0001] This invention relates to the field of motorcycle handlebar technology, specifically to a motorcycle handlebar and rearview mirror shock absorption device. Background Technology

[0002] Motorcycles generate significant vibrations during operation due to road bumps and engine operation. This vibration is particularly pronounced in high-performance motorcycles that prioritize high RPMs, speeds, and comfort. These vibrations cause discomfort for the rider gripping the handlebars and can lead to hand fatigue or even injury over time. Furthermore, they severely affect the stability of the rearview mirrors, making it difficult for the rider to clearly and accurately observe the road behind, significantly reducing riding safety and comfort. While existing motorcycles typically have balancing mechanisms at the ends of the handlebars to absorb vibrations, these mechanisms only absorb vibrations at the ends of the handlebars, resulting in a short absorption distance and poor effectiveness. Moreover, the overall installation reliability of these mechanisms is poor. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a shock absorption device for motorcycle handlebars and rearview mirrors, which has the characteristics of good vibration absorption and high reliability.

[0004] A motorcycle handlebar and rearview mirror shock absorption device comprises: a steering tube 12, a switch 1, and a rubber sleeve 10, characterized in that it includes:

[0005] The shock-absorbing rod 1 has one end near the directional tube that abuts against the shoulder inside the directional tube 12;

[0006] Spline-shaped rubber 2 is sleeved on both ends of the shock-absorbing rod 1 and is interference-fitted with the inner wall of the directional tube 12 to buffer radial vibration of the handle;

[0007] The internal and external threaded assembly 3 is adjustablely connected to the inner wall of the directional tube 12 to limit the axial movement of the shock-absorbing rod 1;

[0008] The handguard 7 is connected to the opening slot 14 of the directional tube 12 by a positioning pin 13, and the opening slot 14 has a reserved gap; a counterweight 8 is provided at the end of the handguard away from the directional tube.

[0009] The rearview mirror 6 is mounted on the handrail 7 via a clamp structure;

[0010] An adjustable gap gasket 4 and a soft rubber 5 are provided between the handguard rod 7 and the internal and external threaded assembly 3, and the overall structure is connected by bolts 9 passing through the counterweight block 8.

[0011] In some embodiments of this utility model, the addition or removal of the gasket 4 can adjust the compression of the soft rubber 5.

[0012] In some embodiments of this utility model, the spline-shaped rubber 3 is provided with a buffer edge 20 for absorbing axial impact.

[0013] In some embodiments of this utility model, the gap of the opening groove 14 is designed to absorb the lateral displacement of the soft rubber 5 during compression.

[0014] The beneficial effects of this utility model are:

[0015] 1. Significant vibration absorption effect: The internal vibration absorption rod (1) and spline rubber (2) absorb radial and axial vibrations, the middle soft rubber (5) further reduces vibrations through compression adjustment, and the external counterweight (8) balances vibration energy. The three work together to significantly reduce the vibration of the handle and rearview mirror.

[0016] 2. Stable and flexible installation: The clamp-shaped rearview mirror (6) mounting base is easy to adjust the angle, the opening groove (14) and positioning pin (13) design ensures installation stability, and the gasket (4) adjustment mechanism adapts to different road conditions.

[0017] 3. Improve cycling safety: Reduce hand fatigue, maintain a clear view in the rearview mirror, and enhance cycling comfort and safety. Attached Figure Description

[0022] The specific structure of the embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0023] Referring to the accompanying drawings, this utility model provides a motorcycle engine suspension rocker structure. Its features are:

[0024] When installing this vibration damping device, first insert the vibration damping rod (1) into the directional tube (12), so that the spline rubber (2) at both ends is interference-fitted with the wall of the directional tube (12) and the spline rubber (2) at the inner end is against the shoulder of the tube wall, ensuring that the spline rubber (2) is installed in place and can play a normal role in buffering radial and axial vibrations; then connect the internal and external threads (3) in the middle to the inner wall of the directional tube (12), and adjust the travel by rotating the internal and external threads (3) to limit the axial movement of the vibration damping rod (1). The external handrail (7) is stepped. The first step is provided with a positioning pin (13) for connecting with the opening groove (14) at the outer end of the steering tube (12). The rearview mirror (6) is installed on the second step. The cavity below the third step contains a counterweight (8). There are gaskets (4) and soft rubber (5) between the internal and external threads (3) and the handrail (7). The rubber sleeve (10) is put on and limited by the auxiliary switch (11). Finally, the bolts (9) are tightened from the counterweight (8) inward to complete the assembly of the entire shock absorption device.

[0025] During the motorcycle ride, when the handlebars are vibrated, the vibration energy is first absorbed and buffered by the internal vibration damping rod (1) and spline rubber (2). The remaining vibration is transmitted to the middle, and the compression of the soft rubber (5) is further reduced by limiting the free travel of the internal and external threads (3), adjusting the gap of the shims (4), and adjusting the torque. Finally, the external counterweight (8) and the handguard (7) work together to dampen the vibration again, ensuring the stability of the rearview mirror (6) and the handlebars.

[0026] The internal vibration damping rod (1) is made of high-density material and has inserted spline-shaped rubber (2) at both ends. This rubber has good elasticity and wear resistance and can effectively absorb and buffer the radial vibration generated by the handle during driving. The buffer edge design of the spline-shaped rubber (2) can play a buffering role when subjected to axial impact, protecting the driver's hands from injury.

[0027] The internal and external thread (3) structure in the middle is connected to the rearview mirror (6). By adjusting the torque and adding or removing the shims (4), the compression of the soft rubber (5) can be changed, thereby flexibly adjusting the shock absorption effect to adapt to different road conditions and driving needs.

[0028] The external counterweight (8) is used to balance the weight of the rearview mirror (6) and reduce vibration caused by weight eccentricity. The positioning pin (13) on the handguard (7) and the slot (14) on the steering tube (12) facilitate the installation and fixation of the device. The gap design in the slot (14) allows some of the compression to enter the gap when the soft rubber (5) is compressed, thereby avoiding lateral collision between the handguard (7) and the steering tube (12).

[0029] The inner and middle ends of the present invention work together to effectively eliminate vibrations from the hand grip to the palm, improving the driver's grip comfort and stability. The outer and middle ends work together to eliminate vibrations from the rearview mirror (6), ensuring clear vision for the driver and improving driving safety.

[0030] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the structure of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
