[0032] The following describes the specific structure and working principle of the brake handle device on one side, i.e. the left side of the bicycle:

[0033] Referring to Figure 1 The shown brake handle device comprises a handlebar 1, a brake handle 2, and a fixing seat 3. The handlebar 1 has a grip part 11 extending along the left-right direction. The brake handle 2 comprises a mounting part 21 extending along the up-down direction, and a handle part 22 extending along the left-right direction from the lower end of the mounting part 21. The fixing seat 3 has a first end part 3a and a second end part 3b. The first end part 3a is fixedly arranged on the handlebar 1, and the upper part of the mounting part 21 is rotatably connected to the second end part 3b about a rotation center line X1 extending along the left-right direction.

[0034] The second end part 3b of the fixing seat 3 is provided with a connecting part 31 for fixing the brake wire 4. The connecting part 31 is arranged at a distance from the rotation center line X1. The lower part of the mounting part 21 has a through hole 211 for the brake wire 4 to slidingly pass through. During the movement of the brake handle 2 rotating about the rotation center line X1 and approaching the handlebar 1, the distance between the connecting part 31 and the through hole 211 gradually increases.

[0035] Referring to Figures 1 to 6As shown, the second end 3b is located in front of the first end 3a, and the brake handle 2 is located entirely in front of the grip portion 11. The extension direction of the grip portion 11, the extension direction of the handle portion 22, and the extension direction of the rotation center line X1 are parallel to each other. Specifically, the fixing base 3 has an extension portion 32 located at the second end 3b and extending in the vertical direction, and a fixing portion 33 extending in the front-rear direction. The rear end of the fixing portion 33 is fixedly connected to the handlebar 1. The extension portion 32 and the fixing portion 33 are integrally provided, and the extension portion 32 extends downward from the front end of the fixing portion 33. The upper part of the mounting portion 21 is rotatably connected to the extension portion 32 around the rotation center line X1, and the handle portion 22 extends to the left from the lower end of the mounting portion 21. The connecting portion 31 is provided on the extension portion 32, and the connecting portion 31 and the rotation center line X1 are provided with a gap in the vertical direction. In this embodiment, the rotation center line X1 is located above the extension portion 32, and the connecting portion 31 is located below the rotation center line X1.

[0036] See Figure 3 , Figure 6 As shown, the mounting part 21 has a hollow channel 213 through which the brake cable 4 can slide. The end of the brake cable 4 is fixedly connected to the connecting part 31, passes through the hollow channel 213 along its own length direction, and exits from the through hole 211 to the bottom of the brake handle 2. Specifically, the brake cable 4 has a limiting end 41 located at its end. The connecting part 31 is a slot for locking and fixing the limiting end 41. In this embodiment, the slot is located at the lower part of the extension part 32. The limiting end 41 is locked in the slot and fixed relative to the extension part 32. The hollow channel 213 is connected to the through hole 211. The brake cable 4 passes through the slot, exits the fixing seat 3, and enters the hollow channel 213 of the mounting part 21.

[0037] In other embodiments, the connecting part 31 may also be located on the left, right or other positions of the extension part 32, as long as the limiting end 41 can always be fixed relative to the extension part 32 during the rotation of the mounting part 21, and there is a gap between the connecting part 31 and the rotation center line X1.

[0038] The brake lever 2 also includes a first connector 23 and a second connector 24, see [link / reference] Figure 4As shown, the first connecting member 23 is fixedly arranged at the bottom of the mounting portion 21, and forms a receiving cavity 25 with the bottom of the mounting portion 21, and the second connecting member 24 is located in the receiving cavity 25; the lower portion of the first connecting member 23 is provided with a first through hole 231, and the brake cable tube 5 and the brake cable 4 extend into the receiving cavity 25 from the first through hole 231, and the end of the brake cable tube 5 is fixed on the bottom of the mounting portion 21 by the second connecting member 24, the second connecting member 24 is provided with a second through hole 241 through which only the brake cable 4 can pass, the second through hole 241 is communicated with the through hole 211 and the receiving cavity 25, the brake cable 4 in the lumen of the brake cable tube 5 passes through the second through hole 241 upwardly into the through hole 211, the brake cable 4 passes through the hollow passage 213 upwardly, and finally the limiting end head 41 at the end of the brake cable 4 is clamped in the clamping groove of the extending portion 32.

[0039] The brake handle device has a braking state and a non-braking state. When the brake handle device is in the braking state, the mounting portion 21 and the extending portion 32 form an acute angle. When the brake handle device is in the non-braking state, the mounting portion 21 and the extending portion 32 abut against each other along the front-rear direction. Specifically, the mounting portion 21 is provided with a receiving groove 212 for the extending portion 32 to be clamped therein. When the brake handle device is in the non-braking state, the extending portion 32 is clamped in the receiving groove 212, and the extending portion 32 and the mounting portion 21 extend along the same direction. When the brake handle device is converted from the non-braking state to the braking state, the extending portion 32 remains stationary, and the mounting portion 21 rotates rearwardly about the rotation center line X1 and approaches the handle portion 11.

[0040] The fixed seat 3 and the brake handle 2 are further provided with an elastic member (not shown in the figure) for providing the force required for driving the handle portion 22 to move away from the handle portion 11. The elastic member can be a torsion spring, which can be arranged between the fixed seat 3 and the mounting portion 21. The torsion spring can provide the force required for the mounting portion 21 to move toward the extending portion 32, which is mainly used for driving the brake handle 2 to rotate and reset during the conversion of the brake handle device from the braking state to the non-braking state.

[0041] When it is required to brake the bicycle, referring to Figures 2 to 6 As shown, the rider holds the handle portion 22 and exerts force rearwardly, so that the brake handle 2 rotates rearwardly about the rotation center line X1, the mounting portion 21 rotates rearwardly and drives the brake cable tube 5 to move rearwardly, the brake cable 4 slides relative to the brake cable tube 5, the length of the brake cable 4 between the through hole 212 and the connecting portion 31 increases, so that the brake cable 4 is pulled, and the brake device on the bicycle frame 100 drives the front wheel assembly 200 or the rear wheel assembly 300 of the bicycle to brake.

[0042] In the braking process, the elastic member between the fixed seat 3 and the brake handle 2 is deformed, and after the braking, the rider only needs to release the hand holding the handle part 22, and under the action of the elastic member, the brake handle 2 automatically moves to the initial position, and the brake handle device is converted to the unbraking state.

[0043] In summary, the brake handle device of the embodiment, the mounting part 21 rotates backward and pulls the brake line 4 backward, thereby realizing the brake operation of the brake device on the bicycle. During the braking process, the brake handle 2 has no angle change, the operator's grip is uniform, and it is more labor-saving. It is especially suitable for children's bicycles.

[0044] The above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and to implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made in accordance with the spirit and essence of the present application shall be covered within the protection scope of the present application.
