Abstract
Description
Technical Field
[0001] This utility model relates to the field of bicycle parts, and more specifically, to an integrated carbon fiber wheel rim. Background Technology
[0002] In existing technology, wheels generally consist of a rim and spokes. Based on the connection method between the rim and spokes, they are divided into split wheels and one-piece wheels. Split wheels have their spokes and rim formed separately and then assembled. One-piece wheels have their spokes and rim formed as a single piece. Traditional one-piece wheels are relatively heavy and have poor strength and shock resistance, making them difficult to meet usage requirements. Existing patent authorization announcement number: CN212400771U, title: Hollow One-Piece Wheel. Although the overall weight is reduced, it uses three one-piece molded spokes for support. Therefore, the stress points of the rim are mainly concentrated at the connection points between the three spokes and the rim. With the stress concentrated at three points, the rim is prone to breakage during use, leading to rim failure and shortening its lifespan. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, this utility model provides an integrated carbon fiber wheel rim, which aims to solve the technical problem that the existing integrated wheels are prone to breakage due to stress concentration.
[0004] This utility model is implemented as follows: an integrated carbon fiber wheel rim includes an integrally formed wheel rim, hub and spokes, at least three support plates are provided near the two end faces of the hub, at least two spokes are provided on one support plate, and the other end of the spokes is connected to the inner side wall of the wheel rim.
[0005] Furthermore, the support plate includes a left support plate and a right support plate disposed on the hub near both ends, and the left support plate and the right support plate are staggered.
[0006] Furthermore, the left support plate and the right support plate each comprise four, with one left support plate having two spokes and one right support plate having two spokes.
[0007] Furthermore, the inner side of the rim has continuous wavy protrusions, and the spokes are connected to the crests of the protrusions.
[0008] Furthermore, all spokes are solid, and the connection between the spokes and the rim is achieved with a rounded transition.
[0009] Furthermore, the rim, hub, and spokes are all integrally molded from carbon fiber material.
[0010] Furthermore, the hub includes a central axle hole, and the inner wall of the axle hole has several strip-shaped grooves along the length of the axle hole.
[0011] The beneficial effects of this utility model are: This utility model discloses an integrated carbon fiber wheel rim with a simple and ingenious design. It includes a one-piece molded rim, hub, and spokes. At least three support plates are positioned near both ends of the hub, with at least two spokes on each support plate. The other end of each spoke connects to the inner wall of the rim. This utility model primarily uses a hub with multiple support plates, each with multiple spokes connecting to the inner wall of the rim. The weight of the bicycle is transmitted from the hub to the support plates, and then through the multiple spokes to the rim. Compared to existing support methods using only three spokes, this method distributes the force to multiple locations on the rim, preventing concentrated stress that could lead to breakage and rim failure, thus extending the rim's lifespan.

[0015] 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 a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0016] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0017] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0018] Please refer to Figure 1-2 This utility model provides an integrated carbon fiber wheel rim 10, including an integrally formed wheel rim 10, hub 20 and spokes 203. At least three support plates are provided near the two end faces of the hub 20. Specifically, the support plates include a left support plate 201 and a right support plate 202 provided near the two end faces of the hub 20. The left support plate 201 and the right support plate 202 are staggered. The staggered design ensures that when the wheel rim 10 touches the ground, the two sides of the hub 20 are not subjected to the same force, preventing the hub 20 from being overloaded and cracking.
[0019] Please refer to Figure 1-2 Each support plate has at least two spokes 203, and the other end of each spoke 203 is connected to the inner wall of the rim 10. Specifically, in this embodiment, the left support plate 201 and the right support plate 202 each include four spokes. One left support plate 201 has two spokes 203, and one right support plate 202 has two spokes 203, that is, 4x2=8 spokes 203 are formed at one end of the hub 20 for support. The left support plate 201 and the right support plate 202 form a total of 16 spokes 203 for support on the rim 10. Compared with the existing support method using three large spokes 203, the multiple spokes 203 support method can distribute the force on the rim 10 and reduce the breakage caused by force concentration. Furthermore, the inner side of the rim 10 has continuous wave-shaped protrusions 101, and the spokes 203 are connected to the crests of the protrusions 101. In this embodiment, there are 16 protrusions 101, each corresponding to a spoke 203. The protrusions 101 increase the support strength for the spokes 203.
[0020] In this embodiment, all spokes 203 are solid, and the connection between the spokes 203 and the rim 10 is made of arc transition. The solid spokes 203 have sufficient support and strength, and the arc transition further avoids stress concentration and further improves the strength and shock resistance of the product.
[0021] In this embodiment, the rim 10, hub 20 and spokes 203 are all integrally molded from carbon fiber material, which is strong and lightweight.
[0022] Please refer to Figure 1-2 The hub 20 includes a central axle hole 204. Several strip-shaped grooves are opened on the inner side wall of the axle hole 204 along the length direction of the axle hole 204. The bicycle front fork thru-axle is inserted into the axle hole 204. The strip-shaped grooves cooperate with the thru-axle to realize the installation and fixation of the thru-axle in the axle hole 204.
[0023] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
