Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and particularly to the field of bicycle and motorcycle technology, specifically a brake vibration damping and noise reduction mechanism and vehicle. Background Technology

[0002] In everyday vehicles, especially electric bicycles (also known as electric-assisted bicycles or E-bikes), electric motorcycles, and some ordinary human-powered bicycles (including two-wheeled and three-wheeled bicycles), disc brakes are generally installed on the wheel hubs. Brakes are achieved by clamping the brake discs with calipers. For example, in front-motor and rear-motor electric bicycles, the disc brake is connected to the side of the motor. Because the hub motor vibrates during riding, the caliper and disc also vibrate when braking suddenly. Sometimes, the vibrations of the motor and brake can resonate, producing severe abnormal noise and causing noise pollution, greatly affecting the user's riding experience. Therefore, it is necessary to find a way to reduce the abnormal noise generated when braking. Similarly, other similar vehicles also experience various vibrations during riding. If the vibration frequency of the vehicle's hub and the disc happens to be the same, it will also produce severe noise, and the aforementioned problem will also exist. Utility Model Content

[0003] The purpose of this utility model is to provide a brake vibration damping and noise reduction mechanism and vehicle to solve the problems mentioned in the background art.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Please see Figures 1-6 A brake vibration damping and noise reduction mechanism includes a vehicle component and a disc 2 installed in a known manner. A gasket 3 is provided on the side of the vehicle component facing the disc 2. The gasket 3 includes a gasket body 300, which is a flexible structure and can be made of silicon substrate, rubber sheet, etc. The gasket 3 isolates the motor 1 from the disc 2.

[0025] In another embodiment of this utility model, the gasket 3 may be provided on the side of the disc 2 facing the vehicle component, or the gasket 3 may be provided on the corresponding parts of the vehicle component and the disc 2.

[0026] In one embodiment of this utility model, the vehicle component is a motor 1.

[0027] Continue reading Figure 6 In one embodiment of the present invention, the gasket 3 further includes an adhesive layer connected to one side of the gasket body 300, and the gasket 3 is connected to the motor 1 through the adhesive layer.

[0028] Further reading Figure 6 In one embodiment of this utility model, an anti-wear layer 301 is provided on the side of the gasket body 300 facing away from the adhesive layer. The anti-wear layer 301 can be made of materials such as resin. That is, the gasket body is located between the anti-wear layer 301 and the adhesive layer. The gasket 3 contacts the disc 2 through the anti-wear layer 301 to increase the service life of the gasket 3.

[0029] Continue reading Figure 4 and Figure 5 In one embodiment of this utility model, the structure of the gasket 3 is the same as the side structure of the motor 1 (here, structure refers only to the shape and size of the inner and outer contours), so that the gasket 3 fully covers the entire side of the motor 1 without hindering the movement of the axle. Here, the side of the motor 1 refers to the end face of the protruding part of the motor. With this design, it is easier to align the gasket 3 completely with the side of the motor 1 during installation, thereby ensuring a good fit.

[0030] Continue reading Figure 5In one embodiment of this utility model, the gasket 3 is a ring structure with multiple through holes 3b arranged around it. The through holes 3b correspond to the bolts on the end face of the motor 1, allowing the bolts to pass through for the fixed installation of the disc 2 and the motor 1. The diameter of these through holes 3b is not less than the diameter of the connecting hole provided on the end face of the motor 1.

[0031] Optionally, wear-resistant rings are provided in some or all of the through holes 3b to reduce the wear of the flexible gasket 3 on the bolts connecting the disc 2 and the motor 1 during vibration and rotation.

[0032] Further reading Figure 5 In one embodiment of this utility model, the gasket 3 has multiple protrusions 3a arranged around its perimeter. The number of protrusions 3a is the same as the number of through holes 3b, and the through holes 3b are correspondingly arranged on the protrusions 3a. This design results in a larger size of the peripheral portion of the through holes 3b, thus improving the overall structural stability of the gasket 3.

[0033] This invention designs a high-temperature resistant, corrosion-resistant, and aging-resistant gasket 3 with a shape and hole positions close to the end face of the motor 1. This gasket is attached to the motor 1, isolating the motor 1 from the disc 2 and providing cushioning and vibration reduction in between. This alters the transmission frequency between the motor 1 and the brake during riding, eliminating resonance between the motor 1 and the brake, and thus eliminating abnormal braking noise during riding.

[0034] In other embodiments of this utility model, the vehicle component can also be a hub or other structure, replacing the aforementioned motor 1 with a hub or other structure, and adapting it to the gasket 3, while other structures remain unchanged.

[0035] This utility model also provides a vehicle, such as an electric bicycle, including the brake vibration damping and noise reduction mechanism described above. Similarly, other vehicles, such as ordinary human-powered bicycles and motorcycles, may experience bumps or vibrations due to other mechanical vibrations during use. If they brake suddenly, the brake pads and the hub they contact may resonate, causing significant noise. Therefore, the aforementioned vibration damping and noise reduction mechanism is also required, replacing the aforementioned motor 1 with a hub that is compatible with the gasket 3, while keeping other structures unchanged.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
