Description

Technical Field

[0001] This utility model relates to the field of bicycle wheel rim technology, and in particular to a frameless hook aluminum alloy bicycle wheel rim. Background Technology

[0002] Frameless hook aluminum alloy rims are a common bicycle rim design, typically used in road bikes, mountain bikes, and racing bikes. The frameless hook design means that the rim edge does not have the traditional hook-shaped part, which can reduce weight and also improve the aerodynamic performance of the rim.

[0003] The spokes inside existing bicycle rims are generally linear, resulting in a relatively singular support point for the rim and a need to improve stability. Furthermore, since the reflective strips on bicycles are usually located behind the seat, it is not easy for riders to notice the bicycle when it is approaching from the side, thus the overall safety performance needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned problems by proposing a frameless hook aluminum alloy bicycle rim. It improves upon the fact that the spokes inside existing bicycle rims are generally linear in design, resulting in a relatively single point of support for the rim and insufficient stability. Furthermore, since the reflective strips of bicycles are generally located behind the seat, it is not easy for the rider to notice the presence of the bicycle when a vehicle approaches from the side, thus the overall safety performance needs to be improved.

[0005] A frameless aluminum alloy bicycle rim includes a rim body, a hub body, a reinforcing support assembly, an auxiliary reinforcing assembly, and a safety warning assembly. The rim body is located on the outer rim of the hub body. The reinforcing support assembly includes a first spoke and a second spoke. The first spoke is circumferentially distributed on the outer side wall of the hub body, and the end of the first spoke is connected to the second spoke. The second spoke is V-shaped, and its end is connected to the inner side wall of the rim body. The safety warning assembly includes auxiliary mounting blocks and reflective strips. Two sets of auxiliary mounting blocks are symmetrically arranged on the outer sides of the rim body. Furthermore, the outer side wall of the auxiliary mounting block is in contact with the outer side wall of the reflective strip; a positioning T-shaped block is provided on the outer side wall of the reflective strip near the position of the auxiliary mounting block, and a positioning T-shaped groove is correspondingly opened on the outer side wall of the auxiliary mounting block, and the positioning T-shaped block and the positioning T-shaped groove are slidably installed; a first threaded groove is symmetrically opened through the outer side wall of the auxiliary mounting block at the position of the positioning T-shaped groove, and a second threaded groove is symmetrically opened on both outer sides of the positioning T-shaped block, and the first threaded groove and the second threaded groove are threadedly installed with the fastening bolt; the second spoke and the inner ring of the wheel rim body form a complete triangular support area.

[0006] Preferably, the auxiliary reinforcement component includes an annular friction pad, which is connected to the inner wall of the outer ring of the wheel rim body through a resin adhesive layer.

[0007] The beneficial effects of this utility model are:

[0008] 1. When using the frameless hook aluminum alloy rim of this bicycle, the spokes are set in a "Y" shape. The Y-shaped spokes optimize the distribution of force, which helps to improve the rigidity of the rim and reduce the possibility of deformation, thereby providing more stable riding performance. At the same time, this spoke shape can more effectively bear the load from all directions, improve the durability of the wheel under high-intensity use, and have excellent overall safety performance.

[0009] 2. The frameless aluminum alloy rim of this bicycle features a ring-shaped friction pad installed inside the rim, which reduces wear between the tire and the rim to a certain extent, thus extending the service life of both. Additionally, the reflective strips installed on the sides of the rim provide a warning when a vehicle approaches from the side. Furthermore, the reflective strips are designed to be detachable, making cleaning and maintenance convenient. The overall structure is ingeniously designed and highly practical.

[0016] 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.

[0017] In practical implementation: such as Figure 1-5 As shown, a frameless aluminum alloy bicycle rim includes a rim body 1, a hub body 2, a reinforcing support component 3, an auxiliary reinforcing component 4, and a safety warning component 5: the rim body 1 is located on the outer ring of the hub body 2.

[0018] The reinforcing support component 3 includes a first spoke 31 and a second spoke 32. The first spoke 31 is circumferentially distributed on the outer side wall of the hub body 2. The end of the first spoke 31 is connected to the second spoke 32. The second spoke 32 is set in a "V" shape, and the end of the second spoke 32 is connected to the inner side wall of the wheel rim body 1.

[0019] Here, the first spoke 31 and the second spoke 32 together form a "Y" shape structure. By optimizing the distribution of force, it helps to improve the rigidity of the wheel rim body 1, reduce the possibility of deformation, and thus provide more stable driving performance.

[0020] The auxiliary reinforcement component 4 includes an annular friction pad 41, which is connected to the inner wall of the outer ring of the wheel rim body 1 through a resin adhesive layer.

[0021] The friction pad here can reduce wear between the tire and the rim to a certain extent, thereby extending the service life of the tire and the rim. In actual installation, it can be glued to the outer ring of the rim body 1 at the tire mounting position using resin glue.

[0022] The safety warning component 5 includes an auxiliary mounting block 51 and a reflective strip 52. Two sets of auxiliary mounting blocks 51 are symmetrically arranged on the outer walls of both sides of the wheel rim body 1, and the outer wall of the auxiliary mounting block 51 is in contact with the outer wall of the reflective strip 52. A positioning T-shaped block 53 is provided on the outer wall of the reflective strip 52 near the position of the auxiliary mounting block 51. A positioning T-shaped groove 54 is correspondingly opened on the outer wall of the auxiliary mounting block 51. The positioning T-shaped block 53 and the positioning T-shaped groove 54 are slidably installed. A first threaded groove 55 is symmetrically opened through the outer wall of the auxiliary mounting block 51 at the position of the positioning T-shaped groove 54. A second threaded groove 56 is symmetrically opened on the outer walls of both sides of the positioning T-shaped block 53. The first threaded groove 55 and the second threaded groove 56 are threadedly installed with the fastening bolt 57.

[0023] By designing a reflective strip 52 on the side of the wheel rim body 1, when a rider encounters a vehicle approaching from the side at night, the reflective strip 52 can effectively alert the rider to the vehicle. When the reflective strip 52 needs to be installed on the side of the wheel rim body 1, simply adjust the reflective strip 52 to the appropriate position and insert the positioning T-shaped block 53 on its side into the corresponding positioning T-shaped groove 54. When the positioning T-shaped block 53 moves to the bottom of the positioning T-shaped groove 54, the first threaded groove 55 and the second threaded groove 56 are in a corresponding overlapping state. Then, simply pass the fastening bolt 57 through the first threaded groove 55 and screw it to the bottom of the second threaded groove 56. Disassembly is the same.

[0024] The second spoke 32 and the inner ring of the wheel rim body 1 form a complete triangular support area; thus, by utilizing the stability property of the triangle, the wheel rim body 1 is strengthened and stabilized by increasing the number of support points.

[0025] In use, the first spoke 31 and the second spoke 32 together form a "Y" shaped structure. By optimizing the force distribution, this helps to improve the rigidity of the wheel rim body 1, reduce the possibility of deformation, and thus provide more stable driving performance.

[0026] The friction pad here can reduce wear between the tire and the rim to a certain extent, thereby extending the service life of the tire and the rim. In actual installation, it can be glued to the outer ring of the tire mounting position on the rim body 1 using resin glue.

[0027] By designing a reflective strip 52 on the side of the wheel rim body 1, when a rider encounters a vehicle approaching from the side at night, the reflective strip 52 can effectively alert the rider to the vehicle. When the reflective strip 52 needs to be installed on the side of the wheel rim body 1, simply adjust the reflective strip 52 to the appropriate position and insert the positioning T-shaped block 53 on its side into the corresponding positioning T-shaped groove 54. When the positioning T-shaped block 53 moves to the bottom of the positioning T-shaped groove 54, the first threaded groove 55 and the second threaded groove 56 are in a corresponding overlapping state. Then, simply pass the fastening bolt 57 through the first threaded groove 55 and screw it to the bottom of the second threaded groove 56. Disassembly is the same.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
