Description

Technical Field

[0001] This utility model relates to the technical field of bicycles, specifically to a high-toughness carbon fiber bicycle rim. Background Technology

[0002] Carbon fiber wheels, through optimized fiber arrangement and resin formulation, maintain lightweight while increasing toughness by more than 30% compared to traditional carbon fiber.

[0003] However, in the use of common wheel rims, when one side of the rim is subjected to greater force, the force cannot be dispersed and absorbed, which may directly lead to indentation of the outer wall of the rim, thus directly affecting the rim's support. Therefore, those skilled in the art have provided a high-toughness carbon fiber bicycle rim to solve the problems mentioned in the background art. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A high-toughness carbon fiber bicycle rim includes a rim body, a first support wall is fixedly installed in the middle of the inner cavity of the rim body, a tire bed area is provided on the outer side of the first support wall, a support cavity is provided on the inner side of the first support wall, and a support mechanism for support is installed in the support cavity.

[0006] Preferably, the support mechanism includes a second support wall, the two sides of which are fixedly connected to the inner side of the first support wall and the wheel rim body, respectively, and the second support wall and the first support wall are arranged perpendicularly.

[0007] Preferably, a third support wall is fixedly installed on both sides of the second support wall, and a fourth support wall is fixedly installed on both sides of the inner side of the first support wall, and the third support wall and the fourth support wall are vertically connected.

[0008] Preferably, a fifth support wall is fixedly installed between the third support wall and the fourth support wall.

[0009] Preferably, the first and second support walls have the same thickness, the third, fourth and fifth support walls have the same thickness, and the thickness of the first and second support walls is greater than the thickness of the third, fourth and fifth support walls.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The support mechanism facilitates the formation of a main support beam by the first and second support walls, and an auxiliary support beam by the third, fourth, and fifth support walls. This allows the support cavity to be isolated into multiple chambers, effectively distributing the load and preventing excessive stress concentration that could lead to overall failure. Furthermore, the third, fourth, and fifth support walls can disperse stress onto the first and second support walls, thereby extending their service life. Attached Figure Description

[0016] The present invention will be further described in detail below with reference to embodiments:

[0017] This utility model discloses a high-toughness carbon fiber bicycle rim. (Refer to...) Figure 1-3 The wheel rim body 1 includes a first support wall 2 fixedly installed in the middle of the inner cavity of the wheel rim body 1, a tire bed area 3 is provided on the outer side of the first support wall 2, a support cavity 4 is provided on the inner side of the first support wall 2, and a support mechanism for support is installed in the support cavity 4.

[0018] By adopting the above technical solution, the present invention, through the set support mechanism, facilitates the formation of a main support beam by the first support wall 2 and the second support wall 5, and an auxiliary support beam by the third support wall 6, the fourth support wall 7 and the fifth support wall 8. This allows the support cavity 4 to be isolated into multiple cavities, thereby effectively distributing the load and preventing excessive stress concentration that could lead to overall failure. Furthermore, the third support wall 6, the fourth support wall 7 and the fifth support wall 8 can disperse the stress onto the first support wall 2 and the second support wall 5, thereby improving the service life of the first support wall 2 and the second support wall 5.

[0019] Reference Figure 1-3The support mechanism includes a second support wall 5, with both sides of the second support wall 5 fixedly connected to the inner sides of the first support wall 2 and the wheel rim body 1, respectively, and the second support wall 5 and the first support wall 2 are arranged perpendicularly.

[0020] By adopting the above technical solution, the first support wall 2 can be used to isolate the tire bed area 3 and the support cavity 4, thereby preventing the tire in the tire bed area 3 from being subjected to pressure.

[0021] Reference Figure 1-3 The second support wall 5 is fixedly installed on both sides of the third support wall 6, and the first support wall 2 is fixedly installed on both sides of the inner side of the fourth support wall 7, and the third support wall 6 and the fourth support wall 7 are vertically connected.

[0022] By adopting the above technical solution, the third support wall 6 and the fourth support wall 7 are set to facilitate the separation of the support cavity 4 in conjunction with the second support wall 5, so that when one cavity is impacted, the other cavities and stiffeners can effectively share the load.

[0023] Reference Figure 1-3 A fifth support wall 8 is fixedly installed between the third support wall 6 and the fourth support wall 7.

[0024] By adopting the above technical solution, the fifth support wall 8 can effectively distribute stress onto the first support wall 2 and the second support wall 5, thereby improving the service life of the first support wall 2 and the second support wall 5.

[0025] Reference Figure 1-3 The first support wall 2 and the second support wall 5 have the same thickness, the third support wall 6, the fourth support wall 7 and the fifth support wall 8 have the same thickness, and the thickness of the first support wall 2 and the second support wall 5 is greater than the thickness of the third support wall 6, the fourth support wall 7 and the fifth support wall 8.

[0026] By adopting the above technical solution, the first support wall 2 and the second support wall 5 can form the main support beam, and the third support wall 6, the fourth support wall 7 and the fifth support wall 8 can form the auxiliary support beam, which can improve its ability to resist impact and absorb vibration.

[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
