Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of materials science and engineering, and particularly relates to a bicycle rim with a durable structure. Background Art
[0002] The bicycle rim is an important part of the bicycle wheel set. It bears the tires, spokes and braking system and is the main force-bearing component when the bicycle is running. The design and materials of the rim have important influences on the performance, weight, durability and cost of the bicycle. The design and manufacture of the bicycle rim is a complex process, which needs to consider various factors, including material selection, structural design, manufacturing process and surface treatment, to ensure that the rim can meet the performance requirements of different types of bicycles.
[0003] At present, the existing bicycle rims have poor durability. Without additional structural layers and reinforcement layers, the durability of the rims may be affected. These layers can provide additional strength and rigidity to help the rims resist impacts and fatigue damage during riding. The performance of the rims, such as rigidity and light weight, will be affected due to the lack of these layers. High-performance bicycles usually require light-weight and high-rigidity rims to improve acceleration performance and reduce energy loss. The rims with poor durability will have cracks or other damages after long-term use, which will increase the safety risks during riding. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a bicycle rim with a durable structure, aiming to solve the problems raised in the above background art.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A bicycle rim with a durable structure includes a surface coating. The inner side of the surface coating is fixedly connected with a main structure layer. The inner side of the main structure layer is fixedly connected with a reinforcement layer. The material of the main structure layer is carbon fiber composite material, and the material of the reinforcement layer is carbon fiber cloth.
[0007] As a preferred scheme of the utility model, the material of the surface coating is epoxy resin, the thickness of the surface coating is one hundred microns, the thickness of the main structure layer is one millimeter, and the thickness of the reinforcement layer is one millimeter.
[0008] As a preferred scheme of the utility model, the inner side of the reinforcement layer is fixedly connected with a lining layer. The material of the lining layer is rubber, and the thickness of the lining layer is one millimeter.
[0009] As a preferred embodiment of the present utility model, a spoke hole layer is fixedly connected to the inner side of the inner lining layer. The spoke hole layer is made of polyurethane material, and the thickness of the spoke hole layer is one hundred micrometers.
[0010] As a preferred embodiment of the present utility model, a brake layer is fixedly connected to the outer side of the spoke hole layer. The brake layer is made of aluminum alloy material, and the thickness of the brake layer is one hundred micrometers.
[0011] As a preferred embodiment of the present utility model, mounting holes are formed on the inner surface of the spoke hole layer, and the number of the mounting holes is set to be several.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0013] 1. For the bicycle rim with a durable structure, by setting the main structure layer, it can effectively provide the necessary hardness and load-bearing capacity for the bicycle rim during use, enabling it to withstand potential impacts and pressures encountered during driving, ensuring that the bicycle can cope with different terrains. While maintaining sufficient rigidity to maintain the wheel shape and provide stable rotation, a certain degree of elasticity can help the rim absorb vibrations and impacts on the road, reduce the impact on the rider, and prevent damage to the rim during large impacts.
[0014] 2. For the bicycle rim with a durable structure, by setting the strengthening layer, it can effectively improve the overall load-bearing capacity of the rim during use, making it more resistant to deformation and damage. It can help the rim better absorb the impact force from the road surface, reduce the pressure directly transmitted to the hub and bearings, thereby providing a smoother riding experience and reducing the wear of other components. By using high-strength materials such as carbon fiber, steel, or special alloys as the strengthening layer, the resistance of the rim to friction and corrosion can be significantly improved, and the service life can be extended.

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0023] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.
[0024] Example 1
[0025] Refer to the figure Figures 1-4 , which is the first embodiment of the utility model, and this embodiment provides a bicycle rim with a durable structure, including a surface coating 1, a main structure layer 2 is fixedly connected to the inner side of the surface coating 1, a reinforcement layer 3 is fixedly connected to the inner side of the main structure layer 2, the main structure layer 2 is made of carbon fiber composite material, and the reinforcement layer 3 is made of carbon fiber cloth.
[0026] Specifically, the surface coating 1 is made of epoxy resin, the thickness of the surface coating 1 is one hundred microns, the thickness of the main structure layer 2 is one millimeter, and the thickness of the reinforcement layer 3 is one millimeter.
[0027] Further: The epoxy resin coating provides a tough protective film that prevents the main structure of the rim from being eroded by the external environment, such as moisture, chemicals and ultraviolet rays. The main structure layer 2 is the core part of the rim. It provides basic shape and structural support to ensure that the rim can withstand various forces and pressures during riding. The reinforcement layer 3 improves the overall strength of the rim by adding additional materials, especially when subjected to lateral forces or impacts, which can reduce the risk of deformation and damage.
[0028] Specifically, an inner lining layer 4 is fixedly connected to the inner side of the strengthening layer 3. The material of the inner lining layer 4 is rubber, and the thickness of the inner lining layer 4 is 1 millimeter.
[0029] Furthermore: The rubber inner lining layer 4 provides additional buffering effect, can absorb vibrations and impacts from the road surface, reduce the impact on the rider, and protect the rim from direct impact. The inner lining layer 4 is used to enhance the sealing between the rim and the tire. Especially when using a tubeless system, the rubber material helps prevent air leakage.
[0030] Specifically, a spoke hole layer 5 is fixedly connected to the inner side of the inner lining layer 4. The material of the spoke hole layer 5 is polyurethane, and the thickness of the spoke hole layer 5 is 100 microns.
[0031] Furthermore: The spoke hole layer 5 made of polyurethane can provide additional support, strengthen the connection between the spokes and the rim, ensure that the spokes will not loosen or damage the rim when stressed. The polyurethane material has a low coefficient of friction, which can reduce the friction between the spokes and the rim, thereby reducing energy loss and improving riding efficiency. The spoke hole layer 5 can also provide waterproof and dustproof functions, protect the inside of the spoke holes from the intrusion of moisture and dust, and maintain the performance of the rim.
[0032] Specifically, a brake layer 6 is fixedly connected to the outer side of the spoke hole layer 5. The material of the brake layer 6 is aluminum alloy, and the thickness of the brake layer 6 is 100 microns.
[0033] Furthermore: The brake layer 6 can provide stable braking performance, ensure rapid heat dissipation during braking, reduce brake fade. The aluminum alloy material is relatively light, which helps to reduce the overall weight of the rim, improve the acceleration performance and handling of the bicycle. Aluminum alloy has good corrosion resistance, can resist the erosion of moisture and chemical substances, and extend the service life of the rim.
[0034] Specifically, mounting holes 7 are formed on the inner surface of the spoke hole layer 5, and the number of the mounting holes 7 is set to several.
[0035] Furthermore: The number and position of the mounting holes 7 provide flexibility, and the number and layout of the spokes can be adjusted according to different wheel designs and riding requirements to achieve the best performance and appearance effects. The several mounting holes 7 mean that different types of spokes and different spoke materials can be adapted, increasing the adaptability and versatility of the rim.
[0036] Working principle:
[0037] During use, by setting the main structure layer 2, it can effectively enable the device to have the necessary hardness and load-bearing capacity for the bicycle rim during use, enabling it to withstand potential impacts and pressures encountered during driving, ensuring that the bicycle can handle different terrains. While maintaining sufficient rigidity to maintain the wheel shape and provide stable rotation, a certain amount of elasticity can help the rim absorb vibrations and impacts on the road, reduce the impact on the rider, and prevent damage to the rim during large impacts. By setting the reinforcement layer 3, it can effectively enable the device to have an improved overall load-bearing capacity of the rim during use, making it more resistant to deformation and damage, and capable of helping the rim better absorb the impact force from the road surface, reducing the pressure directly transmitted to the hub and bearings, thereby providing a smoother riding experience and reducing wear on other components. By using high-strength materials such as carbon fiber, steel, or special alloys as the reinforcement layer 3, the resistance of the rim to friction and corrosion can be significantly improved, and the service life can be extended.
