Description

Technical Field

[0001] This utility model relates to the field of electric bicycles, and in particular to a handlebar frame connection structure and a bicycle. Background Technology

[0002] In the electric bicycle industry, the connection structure between the handlebars and the steering tube is crucial, directly affecting the bicycle's handling performance, safety, and overall stability. However, the handlebar connection structures commonly found on the market today have a series of problems that need to be addressed.

[0003] First, traditional handlebar frame connections are inadequate in terms of stability. Many connections rely solely on simple bolts or clamps. During extended rides, factors such as road bumps and vibrations can cause bolts to loosen and clamps to shift, resulting in a less secure connection between the handlebar frame and the steering tube. This affects the rider's precision in controlling the bicycle and increases riding risks. For example, during mountain biking, complex terrain can subject the bicycle to significant impacts, and traditional connections may loosen, causing the handlebars to wobble and interfering with the rider's normal riding operation.

[0020] In this embodiment 1, like Figures 1 to 5 As shown, this utility model provides a handlebar frame connection structure, including a handlebar frame body 1 and a frame steering tube 2. The handlebar frame body 1 includes a control part 3 and gripping parts 4 extending from both ends of the control part 3. A sleeve 5 for connecting to the frame steering tube 2 extends from the lower end of the control part 3. An arc-shaped surface 6 protrudes from the inner wall of the sleeve 5. A locking groove 7 is arranged on one side of the arc-shaped surface 6 inside the sleeve 5. A locking block 8 is arranged within the locking groove 7. A screw 9 is provided on the control part 3. The screw 9 passes through the control part 3 and is connected to the locking block 8. The frame steering tube 2 is clamped and locked by the arc-shaped surface 6 in conjunction with the locking block 8, and the clamping force of the screw 9 is adjusted by its thread.

[0021] By setting up a handlebar frame connection structure, including a handlebar frame body 1 and a frame steering tube 2, the handlebar frame body 1 includes a control part 3 and a grip part 4. The lower end of the control part 3 is provided with a sleeve 5 with an arc-shaped surface 6 for connecting with the frame steering tube 2. The sleeve 5 has a locking groove 7 and a locking block 8 inside. The control part 3 is provided with a screw 9 that passes through the sleeve 5 and connects to the locking block 8, so that the frame steering tube 2 is clamped and locked by the arc-shaped surface 6 and the locking block 8. The clamping force can be adjusted by the thread of the screw 9, so that the connection between the handlebar frame and the frame steering tube 2 is stable and flexible, meeting different installation requirements.

[0022] The arc-shaped surface 6 has a locking end 10 along the outer wall of the sleeve 5. The frame steering tube 2 has a fixing hole 11 corresponding to the locking end 10. The sleeve 5 and the frame steering tube 2 are bolted together by bolts passing through the locking end 10 and the fixing hole 11.

[0023] By opening a locking end 10 along the outer wall of the sleeve 5 on the arc surface 6, and providing a corresponding fixing hole 11 for the frame steering tube 2, the sleeve 5 and the frame steering tube 2 can be bolted together by passing a bolt through the locking end 10 and the fixing hole 11, which further enhances the stability and reliability of the connection structure and prevents loosening or displacement between the handlebar frame and the frame steering tube 2.

[0024] The opposite surface of the locking block 8 and the arc-shaped surface 6 is a clamping surface 12 that matches the outer wall of the frame steering tube 2.

[0025] By setting the opposite surface of the locking block 8 and the arc-shaped surface 6 to a clamping surface 12 that matches the outer wall of the frame steering tube 2, good contact and fit between the locking block 8 and the frame steering tube 2 are ensured, and the clamping force can be transmitted more evenly, thereby improving the stability of the entire connection structure and ensuring the stability of the handlebar frame during riding.

[0026] The cross-section of the locking block 8 is thinner at the top and thicker at the bottom.

[0027] By setting the cross-section of the locking block 8 to be thinner at the top and thicker at the bottom, the locking block 8 can better transmit the force to the part in contact with the steering tube 2 of the frame when it is subjected to the tension of the screw 9, thereby enhancing the clamping effect and making the structure more stable and less prone to deformation.

[0028] The locking groove 7 has a cross-section that is thicker at the top and thinner at the bottom.

[0029] By setting the cross-section of the locking groove 7 to be thicker at the top and thinner at the bottom, which matches the shape of the locking block 8, it helps to guide the locking block 8 to be accurately positioned in the groove. Furthermore, when the locking block 8 is under force, the groove can better bear and disperse the stress, ensuring the reliability of the connection structure.

[0030] The sleeve 5 has a wire passage 13 for the frame wiring harness to pass through.

[0031] By creating a cable passage 13 inside the sleeve 5 for the frame harness to pass through, the frame harness can pass through the handlebar frame connection in an orderly manner, avoiding problems such as tangling and wear caused by exposed harnesses, thus improving the overall neatness and safety of the bicycle.

[0032] A bicycle, including a handlebar frame connection structure as described above.

[0033] By designing a bicycle with the aforementioned handlebar frame connection structure, the connection between the handlebar frame and the frame steering tube 2 is made more stable, reliable, and easy to adjust. At the same time, the wiring harness arrangement is optimized, improving the overall performance, safety, and aesthetics of the bicycle.

[0034] In this embodiment 2, like Figures 1 to 5 As shown, this utility model incorporates a handlebar frame connection structure and bicycle, including a handlebar frame body 1 and a frame steering tube 2. The handlebar frame body 1 features a control part 3, a grip part 4, and a sleeve 5 with an arc-shaped surface 6 and a locking groove 7. These components, along with a locking block 8 and a screw 9, achieve a stable and adjustable clamping mechanism. A bolt connection between the locking end 10 and the fixing hole 11 enhances stability. The matching shape of the locking block 8 and the groove improves clamping and structural stability, and the specific clamping surface 12 of the locking block 8 evenly transmits force. The cable passage 13 within the sleeve 5 allows for orderly arrangement of the frame wiring harness, preventing tangling and wear, and improving overall neatness and safety.

[0035] In this embodiment 3, like Figures 1 to 5 As shown, in this utility model, the handlebar frame body 1 is composed of a control part 3 and gripping parts 4 extending from both ends of the control part 3. The sleeve 5 extending from the lower end of the control part 3 is used to connect with the frame steering tube 2. The raised arc-shaped surface 6 on the inner wall of the sleeve 5 provides a close contact surface for the frame steering tube 2, which helps to initially position and stabilize the frame steering tube 2.

[0036] like Figures 1 to 5 As shown, in this utility model, a locking groove 7 is arranged on the opposite side of the arc-shaped surface 6 inside the sleeve 5, and a locking block 8 is placed in the groove. The surface of the locking block 8 opposite to the arc-shaped surface 6 is a clamping surface 12 that matches the outer wall of the frame steering tube 2. These two surfaces work together to clamp the frame steering tube 2. A screw 9, located on the control section 3, passes through the sleeve 5 and connects to the locking block 8. When it is necessary to fasten the handlebars to the frame steering tube 2, rotating the screw 9 converts the rotation into axial tension, as it is connected to the locking block 8. Because the locking block 8 has a cross-section that is thinner at the top and thicker at the bottom, while the locking groove 7 has a cross-section that is thicker at the top and thinner at the bottom, this fit allows the locking block 8 to move stably within the locking groove 7 under tension and move closer to the frame steering tube 2, thereby increasing the clamping force on the frame steering tube 2. This achieves a secure clamping of the frame steering tube 2 through the arc-shaped surface 6 and the locking block 8. Simultaneously, by precisely rotating the screw 9 and utilizing the characteristics of the thread, the clamping force can be precisely adjusted to adapt to different installation requirements and factors such as the material of the frame steering tube 2.

[0037] In this embodiment 4, like Figures 1 to 5 As shown, in this invention, the arc-shaped surface 6 has a locking end 10 along the outer wall of the sleeve 5, and a corresponding fixing hole 11 is provided on the frame steering tube 2. After the initial clamping of the locking block 8 and the screw 9 is completed, the bolt is passed through the locking end 10 and the fixing hole 11 for bolt connection. The tightening of the bolt further constrains the relative position between the sleeve 5 and the frame steering tube 2, preventing loosening or displacement between the handlebar frame and the frame steering tube 2 due to vibration and other factors during riding, greatly enhancing the stability and reliability of the entire connection structure.

[0038] In this embodiment 5, like Figures 1 to 5 As shown, in this invention, the cable passage 13 inside the sleeve 5 is mainly used for the passage of the frame wiring harness. During the bicycle assembly process, various wiring harnesses on the frame, such as brake cables, gear cables, and power cables, can be arranged in an orderly manner through this cable passage 13, extending from the frame to the control section 3 of the handlebars. This avoids the messy distribution of wiring harnesses at the connection between the handlebars and the frame, reduces the risk of wiring harnesses becoming tangled and damaged due to friction and wear, ensures the stability of signal transmission and power transmission between various components of the bicycle, and also improves the overall neatness and aesthetics of the bicycle.
