[0033] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0034] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0035] This application discloses a vehicle frame.
[0036] Reference Figure 1 and Figure 2The frame includes a frame body 1, a front fork 2, a handlebar 3, and a connector 4. The frame body 1, front fork 2, and handlebar 3 are all made of carbon fiber, and the front fork 2 and handlebar 3 are formed by hot pressing with a mold to make the front fork 2 and handlebar 3 integrally molded. One end of the frame body 1 is located between the front fork 2 and the handlebar 3, so that the lower end of the connector 4 can be sequentially inserted into the handlebar 3 and the frame body 1, and the lower end of the connector 4 is threaded into the front fork 2. The upper end of the connector 4 abuts against the handlebar 3 to complete the installation between the frame body 1 and the front fork 2 and handlebar 3, so as to realize the rotational connection between the frame body 1 and the front fork 2 and handlebar 3.
[0037] During frame assembly, since the front fork 2 and handlebar 3 are integrally molded, only one end of the frame body 1 needs to be placed between the front fork 2 and handlebar 3. Then, the connector 4 is threaded through the handlebar 3 and frame body 1 and connected to the front fork 2, thus assembling the frame body 1, front fork 2, and handlebar 3. The structure is simple and easy to operate, facilitating frame assembly. Furthermore, after long-term use, the angle between the integrally molded front fork 2 and handlebar 3 is less likely to shift, ensuring the stability and safety of the carbon fiber bicycle.
[0038] In some embodiments, a first limiting groove 11 is formed in the lower side of the frame body 1 near the front fork 2. The connection between the front fork 2 and the frame body 1 is limited in the first limiting groove 11, making the connection between the frame body 1 and the front fork 2 tighter. At the same time, the frame body 1 can abut against and be limited in the front fork 2 to improve the stability of the frame assembly.
[0039] In some embodiments, a second limiting groove 12 is formed in the upper side of the frame body 1 near the front fork 2. The connection between the handlebar 3 and the frame body 1 is limited in the second limiting groove 12, making the connection between the frame body 1 and the handlebar 3 tighter. This makes the frame body 1 stably limited between the front fork 2 and the handlebar 3, thereby further improving the stability of the frame assembly.
[0040] Reference Figure 2 and Figure 3 In some embodiments, the lower side of the upper end of the fork 2 is recessed to form two grooves 21, and the two sides of the handlebar 3 near the end of the fork 2 are protruding to form two inserts 31. The shape of the inserts 31 is adapted to the shape of the grooves 21, so that the two inserts 31 are respectively embedded in the two grooves 21, making the connection between the fork 2 and the handlebar 3 tighter, thereby improving the stability of the integral molding between the fork 2 and the handlebar 3.
[0041] In some embodiments, the ends of the two inserts 31 that are far apart from each other are provided with rounded corners 32, so that the inserts 31 can be more stably embedded in the grooves 21, further improving the stability of the integral molding between the fork 2 and the handlebar 3.
[0042] Reference Figure 3 In some embodiments, the handle 3 is recessed to form a relief groove 33, and the upper end of the connector 4 is located in the relief groove 33 to hide the connector 4, thereby improving the overall aesthetics of the frame and reducing the safety hazards caused by the protrusion of the connector 4.
[0043] In some embodiments, the frame further includes a baffle 5. The handlebar 3 is recessed above the relief groove 33 to form a snap-fit groove 34. The baffle 5 snaps into the snap-fit groove 34 to block the connector 4, thereby reducing the aging and rusting of the connector 4. Furthermore, the upper side of the baffle 5 is flush with the handlebar 3 to ensure the flatness of the handlebar 3, thus ensuring the aesthetics of the handlebar 3.
[0044] The implementation principle of this embodiment is as follows: During the assembly process, since the front fork 2 and handlebar 3 are integrally formed, only one end of the frame body 1 needs to be placed between the front fork 2 and handlebar 3. Then, the connector 4 is inserted through the handlebar 3 and the frame body 1 and threaded into the front fork 2 to achieve the assembly of the frame body 1, front fork 2, and handlebar 3. The structure is simple and the operation is convenient, thus facilitating the assembly of the frame. At the same time, after long-term use, the angle between the integrally formed front fork 2 and handlebar 3 is not easily shifted, ensuring the stability and safety of the carbon fiber bicycle.
[0045] This application also discloses a carbon fiber bicycle.
[0046] The carbon fiber bicycle includes the frame described in the above embodiments.
[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
