Description

Technical Field

[0001] This invention relates to a handlebar angle adjustment device. Background Technology

[0002] The handlebars of common bicycles, electric bicycles, and motorcycles are directly fixed to the frame without any angle adjustment function. This makes it difficult for riders with different riding habits to find the most comfortable riding posture. In addition, the handlebars of common bicycles are equipped with connecting bolts, which prevents the brake cables, harness cables, etc. from being routed inside the handlebars and can only be exposed. This affects the lifespan of the brake cables, harness cables, etc., and also affects the aesthetics of the bicycle. Summary of the Invention

[0003] The purpose of this invention is to provide a handlebar angle adjustment device.

[0004] According to one aspect of the present invention, a handlebar angle adjustment device is provided, comprising a handlebar frame, a handlebar A, and an adjustment component A.

[0005] One end of the handlebar frame is equipped with a bevel external gear A.

[0006] One end of the adjusting component A is provided with a beveled internal gear A, and the other end of the adjusting component A is provided with a beveled external gear B.

[0007] One end of handlebar A is equipped with a bevel internal gear B.

[0008] The beveled external gear A meshes with the beveled internal gear A, and the beveled external gear B meshes with the beveled internal gear B.

[0009] In this invention, the handlebar A and the adjusting component A are connected by the meshing of a beveled external gear B and a beveled internal gear B. When the angle of the handlebar A needs to be adjusted, the handlebar A is lifted, separating the beveled internal gear B on the handlebar A from the beveled external gear B on the adjusting component A. Then, the handlebar A is rotated according to the angle adjustment requirements. After the handlebar A has rotated a certain angle, the beveled internal gear B on the handlebar A is re-meshed with the beveled external gear B on the adjusting component A. The minimum adjustment angle θ1 of the handlebar A is determined by the number of teeth of the beveled external gear B and the beveled internal gear B. Since the adjusting component A and the handlebar frame are connected by the meshing of the beveled external gear A and the beveled internal gear A, the overall angle of the adjusting component A and the handlebar A can also be adjusted. The adjusting component A is lifted, separating the beveled internal gear A on the adjusting component A from the beveled external gear A on the handlebar frame. Then, the adjusting component A is rotated according to the angle adjustment requirements. After component A rotates a certain angle, the bevel internal gear A on component A re-meshes with the bevel external gear A on the handlebar frame. The minimum adjustment angle θ2 of component A and handlebar A as a whole is determined by the number of teeth of the bevel external gear A and the bevel internal gear A. In addition, when the adjustment direction of individual handlebar A is the same as the adjustment direction of component A, the minimum adjustment angle of handlebar A as a whole is θ1+θ2. When the adjustment direction of individual handlebar A is opposite to the adjustment direction of component A, the minimum adjustment angle of handlebar A as a whole is θ1-θ2 or θ2-θ1. Therefore, the minimum adjustment angle of handlebar A can be θ1, θ2, θ1+θ2, or θ1-θ2 / θ2-θ1. Different riders can choose the minimum adjustment angle of handlebar A according to their own riding posture needs to find the most comfortable riding posture. It is highly applicable and can basically meet the handlebar angle adjustment needs of all riders.

[0010] In some embodiments, both the bevel external gear A and the bevel internal gear A can have forty-five teeth. Therefore, the minimum adjustment angle θ2 of the adjusting component A and the handlebar A as a whole is 360° / 45 = 8°.

[0011] In some implementations, both the bevel external gear B and the bevel internal gear B can have thirty teeth. Therefore, the minimum adjustment angle θ1 of the individual handlebar A is 360° / 30 = 12°.

[0012] In some embodiments, the bevel external gear A, the adjusting component A, and the bevel internal gear B can be hollow. Therefore, since the bevel external gear A, the adjusting component A, the bevel internal gear B, the handlebar frame, and the handlebar A are all hollow, the brake cables and harnesses can be routed inside the handlebar A, the adjusting component A, and the handlebar frame, eliminating the need for external installation. This improves the lifespan of the brake cables and harnesses, and also enhances the aesthetics of the bicycle.

[0013] In some embodiments, the bicycle may also include a handlebar B and an adjustment component B. The other end of the handlebar frame is provided with a bevel external gear C, which has the same structure as the bevel external gear A. The handlebar B has the same structure as the handlebar A, and the adjustment component B has the same structure as the adjustment component A. The other end of the handlebar frame is connected to the handlebar B via the adjustment component B. Therefore, the minimum adjustment angles of the handlebars A and B can be θ1, θ2, θ1+θ2, or θ1-θ2 / θ2-θ1. Different riders can choose the minimum adjustment angle of the handlebars A and B according to their own riding posture needs, thereby finding the most comfortable riding posture. This design is highly adaptable and can basically meet the handlebar angle adjustment needs of all riders.

[0014] In some embodiments, it may also include a sleeve A, which is fitted onto the handlebar frame. The handlebar frame has an anti-detachment component to prevent the sleeve A from coming off. The anti-detachment component is located inside the sleeve A. The sleeve A has an internal thread, and one end of the handlebar A has an external thread, with the internal thread engaging with the external thread.

[0015] When the internal and external threads are fully engaged, the beveled external gear A and the beveled internal gear A are engaged together and cannot rotate, and the beveled external gear B and the beveled internal gear B are engaged together and cannot rotate.

[0016] Therefore, sleeve A can firmly integrate the bevel external gear A on the handlebar frame, the adjusting component A, and the bevel internal gear B on the handlebar A. When the internal thread on sleeve A is tightened with the external thread on the handlebar A, the bevel external gear A on the handlebar frame and the bevel internal gear A on the adjusting component A are fully engaged, and the bevel external gear B on the adjusting component A and the bevel internal gear B on the handlebar A are fully engaged. At this time, the angle of the handlebar A and the adjusting component A is fixed and cannot be adjusted. When it is necessary to adjust the angle of the handlebar A, loosen the internal thread on sleeve A and the external thread on the handlebar A. At this time, the angle of the handlebar A can be adjusted individually, or the angle of the adjusting component A and the handlebar A as a whole can be adjusted. After the adjustment is completed, tighten sleeve A. The adjustment action is very convenient.

[0017] In some embodiments, the anti-detachment component can be a retaining ring, the handlebar frame can have a groove along its circumference, the retaining ring is accommodated in the groove, and the inner wall of the sleeve A has a protrusion along its circumference.

[0018] When the internal and external threads are fully engaged, the retaining ring rests against the protrusion.

[0019] Therefore, the presence of the retaining ring prevents the sleeve A from coming off the end of the handlebar frame, that is, the beveled external gear A at the end of the handlebar frame cannot come off the sleeve A. When the internal thread and the external thread are fully engaged, the presence of the retaining ring ensures that the beveled external gear A and the beveled internal gear A are fully engaged and will not separate, and the beveled external gear B and the beveled internal gear B are fully engaged and will not separate. Thus, after the angle of the handlebar A is adjusted, the handlebar A will not rotate arbitrarily.

[0020] In some embodiments, the retaining ring may include a semi-circular retaining ring A and a semi-circular retaining ring B, both of which are received in a groove, with the two free ends of retaining ring A respectively mating with the two free ends of retaining ring B. Thus, the semi-circular retaining rings A and B facilitate the installation and removal of the retaining rings from the groove.

[0021] In some embodiments, the outer wall of the sleeve A may have multiple parallel recessed grooves arranged axially. Therefore, when the rider twists the sleeve A, the recessed grooves can increase the rotational friction, facilitating the tightening and loosening of the sleeve A.

[0022] In some embodiments, the outer wall of the sleeve A may be provided with two slots, which are arranged parallel to each other and located on both sides of the outer wall of the sleeve A. Thus, the rider can also use a clamp to wedge the sleeve A in the two slots, making it very easy to tighten and loosen the sleeve A. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0028] Figures 1 to 3 The diagram schematically illustrates the structure of a handlebar angle adjustment device according to one embodiment of the present invention.

[0029] refer to Figures 1 to 3 A handlebar angle adjustment device includes a handlebar frame 1, a handlebar A2, and an adjustment component A3. Alternatively, the handlebar angle adjustment device may also include a handlebar B4, an adjustment component B, a sleeve A5, a retaining ring 6, and a sleeve B7.

[0030] refer to Figure 2 A beveled external gear A11 is installed on the right end of the handlebar frame 1. The beveled external gear A11 and the handlebar frame 1 can be integrally formed, or they can be connected by a threaded structure or a plug-in structure to ensure that the beveled external gear A11 can be firmly installed on the end of the handlebar frame 1.

[0031] refer to Figure 2 and Figure 3 The lower end of the adjusting component A3 is formed with a concave beveled internal gear A31, which can mesh with the beveled external gear A11 on the handlebar frame 1. The upper end of the adjusting component A3 is formed with a beveled external gear B32.

[0032] refer to Figure 3 The lower end of the handlebar A2 is formed with a concave beveled internal gear B21, which can mesh with the beveled external gear B32 of the adjusting component A3.

[0033] refer to Figure 2 and Figure 3 The handlebar frame 1 is connected to the adjusting component A3 through the meshing of the beveled external gear A11 and the beveled internal gear A31. The adjusting component A3 is connected to the handlebar A2 through the meshing of the beveled external gear B32 and the beveled internal gear B21.

[0034] refer to Figure 2In this embodiment, the number of teeth on the bevel external gear A11 on the handlebar frame 1 is 45, and the number of teeth on the bevel internal gear A31 on the adjusting component A3 is 45. The bevel external gear A11 and the bevel internal gear A31 mesh properly. Therefore, the minimum rotation angle θ2 of the adjusting component A3 on the handlebar frame 1 is 360° / 45 = 8°. That is, the minimum adjustment angle of the adjusting component A3 and the handlebar A2 as a whole is θ2 = 360° / 45 = 8°. In other embodiments, the number of teeth on the bevel external gear A11 and the bevel internal gear A31 can be adjusted according to the angle adjustment requirements, ensuring that the number of teeth on the bevel external gear A11 and the bevel internal gear A31 are the same and mesh properly.

[0035] refer to Figure 2 In this embodiment, the number of teeth on the bevel external gear B32 on the adjusting component A3 is thirty, and the number of teeth on the bevel internal gear B21 on the handlebar A2 is thirty. The bevel external gear B32 and the bevel internal gear B21 mesh properly. Therefore, the minimum rotation angle θ1 of the handlebar A2 on the adjusting component A3 is 360° / 30 = 12°. In other embodiments, the number of teeth on the bevel external gear B32 and the bevel internal gear B21 can be adjusted according to the angle adjustment requirements, ensuring that the number of teeth on the bevel external gear B32 and the bevel internal gear B21 are the same and that they mesh properly.

[0036] refer to Figure 2 The handlebars A2 and the adjustment component A3 can be adjusted independently. When the angle of the adjustment component A3 is adjusted, the handlebars A2 can also be adjusted simultaneously. When the adjustment direction of the handlebars A2 is the same as that of the adjustment component A3, the minimum overall adjustment angle of the handlebars A2 is θ1 + θ2 = 12° + 8° = 20°. When the adjustment direction of the handlebars A2 is opposite to that of the adjustment component A3, the minimum overall adjustment angle of the handlebars A2 is θ1 - θ2 = 12° - 8° = 4°. Therefore, the minimum adjustment angle of the handlebars A2 can be θ1 = 12°, θ2 = 8°, θ1 + θ2 = 20°, or θ1 - θ2 = 4°. Different riders can choose the minimum adjustment angle of the handlebars A2 (4°, 8°, 12°, 20°) according to their own riding posture needs to find the most comfortable riding posture. It is highly applicable and can basically meet the handlebar angle adjustment needs of all riders.

[0037] refer to Figure 1 and Figure 2 The sleeve A5 is fitted onto the handlebar frame 1. The upper opening of the sleeve A5 has an internal thread 51 formed therein, and the lower outer wall of the handlebar A2 has an external thread 22 formed therein. The internal thread 51 on the sleeve A5 engages with the external thread 22 on the handlebar A2, that is, the sleeve A5 can be screwed onto the handlebar A2. Figure 1(As shown in the figure) The handlebar frame 1 is provided with an anti-detachment component to prevent the sleeve A5 from coming off the handlebar frame 1. The anti-detachment component is located in the sleeve A5.

[0038] refer to Figure 2 The anti-slip component is a retaining ring 6. A groove 12 is formed circumferentially along the upper edge of the handlebar frame 1. The retaining ring 6 is accommodated in the groove 12, and its outer periphery protrudes from the outer wall surface of the handlebar frame 1. (See reference...) Figure 3 The inner wall of sleeve A5 has a circumferentially formed protrusion 52. When the internal thread 51 on sleeve A5 is fully engaged with the external thread 22 on handlebar A2 ( Figure 1 As shown in the diagram, the retaining ring 6 installed on the handlebar frame 1 is just abutting against the protrusion 52 on the inner wall of the sleeve A5. Figure 3 (As shown in the diagram), at this time, the bevel external gear A11 on the handlebar frame 1 and the bevel internal gear A31 on the adjusting component A3 are fully engaged and cannot rotate relative to each other. The bevel external gear B32 on the adjusting component A3 and the bevel internal gear B21 on the handlebar A2 are also fully engaged and cannot rotate relative to each other. The sleeve A5 can firmly integrate the bevel external gear A11 on the handlebar frame 1, the adjusting component A3, and the bevel internal gear B21 on the handlebar A2. When the internal thread 51 on the sleeve A5 is tightened with the external thread 22 on the handlebar A2, the angle of the handlebar A2 and the adjusting component A3 is fixed and cannot be adjusted. When it is necessary to adjust the angle of the handlebar A2, loosen the internal thread 51 on the sleeve A5 and the external thread 22 on the handlebar A2. At this time, the angle of the handlebar A2 can be adjusted individually, or the angle of the adjusting component A3 and the handlebar A2 as a whole can be adjusted. After the adjustment is completed, tighten the sleeve A5. The adjustment action is very convenient.

[0039] refer to Figure 2 The retaining ring 6 includes retaining ring A61 and retaining ring B62. Both retaining ring A61 and retaining ring B62 are semi-circular in shape. The two free ends of retaining ring A61 can be connected to the two free ends of retaining ring B62 respectively. After connecting retaining ring A61 and retaining ring B62 together, a circular retaining ring 6 is formed. Both retaining ring A61 and retaining ring B62 are accommodated in the groove 12, and the outer periphery of retaining ring A61 and retaining ring B62 protrudes from the outer wall surface of the handlebar frame 1. The semi-circular shape of retaining ring A61 and retaining ring B62 facilitates the installation of retaining ring 6 into the groove 12 and the removal of retaining ring 6 from the groove 12.

[0040] refer to Figure 1 and Figure 2 Multiple parallel recessed grooves 53 are formed on the outer wall of the sleeve A5 along the axial direction. When the rider twists the sleeve A5, the recessed grooves 53 can increase the rotational friction, making it easier to tighten and loosen the sleeve A5.

[0041] refer to Figure 2Two slots 54 are formed on the outer wall of the sleeve A5. The two slots 54 are arranged in parallel and located on both sides of the outer wall of the sleeve A5. The rider can also use a clamp to wedge the sleeve A5 in the two slots 54. Tightening and loosening the sleeve A5 with the clamp is very effortless.

[0042] refer to Figure 2 and Figure 3 The beveled external gear A11 is hollow, the adjusting component A3 is hollow, and the beveled internal gear B21 is hollow. Since both the handlebar frame 1 and the handlebar A2 are hollow, that is... Figure 3 In the middle F direction, the handlebars A2, bevel internal gear B21, adjustment component A3, bevel external gear A11, and handlebar frame 1 are all connected without any obstruction. Therefore, the brake cables and harnesses on bicycles, electric bicycles, and motorcycles can be routed from inside the handlebars A2, adjustment component A3, and handlebar frame 1 without being exposed. This can improve the service life of the brake cables and harnesses, as well as enhance the aesthetics of the vehicle.
