[0051] Next, a brake handle provided in the embodiments of the present application will be described in detail in conjunction with the accompanying drawings through specific embodiments and their application scenarios.

[0052] Embodiment 1:

[0053] As Figures 1 to 3 shown, the embodiment of the present application provides a brake handle, which includes a handle 1, a brake lever main body 2, a rotating shaft 3, a pressing block 4, a brake power-off switch 5, a hydraulic structure 6, and a mounting component 7; it further includes: a locking structure 8, which is used to lock the brake state.

[0054] Further, the locking structure 8 includes a locking block 81, which is movably connected to the brake lever main body 2; a locking groove 82, which is provided on the handle 1; and a return spring 83, which is used to reset the locking block 81.

[0055] Further, the locking block 81 includes a pressing portion 811, which is provided at one end of the locking block 81 away from the brake lever main body 2; a protruding portion 812, which is used to cooperate with the locking groove 82; and a reset portion 813, which is connected to one end of the return spring 83.

[0056] Further, the locking groove 82 includes a first locking groove 821, which is provided at one end of the handle 1 close to the locking block 81; a second locking groove 822, which is provided at the end of the first locking groove 821; and a third locking groove 823, which is provided at the end of the second locking groove 822.

[0057] Further, the locking structure 8 further includes a mounting hole 84, which is provided on the brake lever main body 2 and the locking block 81; and a fixing bolt 85, which is provided in the mounting hole 84.

[0058] In this embodiment of the present application, due to the adoption of the above structure, an installation component 7 is provided at the lower end of the brake lever body 2. The installation component 7 is used to install the brake lever body 2 on the handlebar. The handle 1 and the brake lever body 2 are movably connected together through a rotating shaft 3, so that the handle 1 can rotate around the rotating shaft 3. The handle 1 is used to perform a braking action to provide braking force, or perform a release action to release the braking force. The user can perform a braking action by pressing the handle 1, causing the handle 1 to rotate around the rotating shaft 3 and approach the handlebar. During this process, the end of the handle 1 will squeeze the hydraulic device 6, thereby generating braking force. A pressing block 4 is also provided on the handle, and a brake power-off switch 5 is provided on the brake lever body 2. The brake power-off switch 5 is used to cut off the power supply to the motor during braking. In the normal state, the pressing block 4 abuts against the brake power-off switch 5. When the handle 1 is pressed, the pressing block 4 will separate from the brake power-off switch 5. At this time, the brake power-off switch 5 cuts off the power supply to the motor, which can effectively protect the controller from being damaged during forced stop;

[0059] The locking block 81 and the brake lever body 2 are rotatably connected together through an installation hole 84 and a fixing bolt 85, so that the locking block 81 rotates around the axis of the fixing bolt 85. A return spring 83 is installed on the fixing bolt 85. One end of the return spring 83 is connected to the reset portion 813 of the locking block 81, and the other end is provided on the brake lever body 2. When the user needs to maintain the braking state for a long time, the pressing portion 811 on the locking block 81 can be pressed, so that the locking block 81 rotates around the axis of the fixing bolt 85. When the locking block 81 rotates to the locking groove 82, the protruding portion 812 on the locking block 81 abuts against the locking groove 82, thereby realizing the parking effect of the electric vehicle and liberating the user's hands. The locking groove 82 is successively a first locking groove 821, a second locking groove 822, and a third locking groove 823 from top to bottom. The user can freely select one of the first locking groove 821, the second locking groove 822, and the third locking groove 823 according to needs to realize the parking effect. When the user needs to release the parking state, by continuing to press the handle 1 in the direction of the handlebar, the protruding portion 812 of the locking block 81 disengages from the locking groove 82. The reset portion 813 on the locking block 81 is affected by the elastic force of the return spring 83, and the locking block 81 automatically resets to the initial position, which is simple and convenient to operate.

[0060] Embodiment 2:

[0061] As Figures 1 to 4 shown, in this embodiment, in addition to including the structural features of the foregoing embodiment, it further includes a connecting portion 91 that divides the handle 1 into a main handle 911 and a branch handle 912; a positioning portion 92 that is provided inside the handle 1; and a limit adjusting rod 93 that is provided at a position where the main handle 911 is close to the branch handle 912.

[0062] Further, the positioning portion 92 includes a positioning block 921 disposed on the limit adjusting rod 93; and a positioning hole 922 disposed near the main handle 911 of the support handle 912.

[0063] Further, the positioning block 921 is an isosceles triangle block.

[0064] Further, the limit adjusting rod 93 further includes a first limit post 931 disposed at one end of the main handle 911 close to the support handle 912; and a second limit post 932 disposed within the first limit post 931.

[0065] Further, it further includes: an adjustment button 94 disposed on the positioning block 921; and a spring 95, one end of which is fixedly connected to the main handle 911 and the other end of which is fixedly connected to one end of the positioning block 921 facing away from the adjustment button 94.

[0066] In this embodiment of the present application, due to the adoption of the above structure, the handle 1 is divided into the main handle 911 and the support handle 912 by the connecting portion 91. The support handle 912 is connected to the brake lever body 2. A spring 95 is fixedly disposed on the main handle 911. A limit adjusting rod 93 is nested inside the spring 95. A positioning block 921 is fixedly disposed on the side of the spring 95 away from the main handle 911. An adjustment button 94 is fixedly disposed on the other side of the positioning block 921. One side of the positioning block 921 facing the main handle 911 is connected to the second limit post 932. The second limit post 932 is disposed within the first limit post 931. The first limit post 931 is movably connected to the second limit post 932. The second limit post 932 can freely move along the axis of the first limit post 931. Five positioning holes 922 are equidistantly disposed within the support handle 912. The distance between the handle 1 and the handlebar can be conveniently adjusted by the arrangement of the multiple positioning holes 922. The positioning block 921 is slidably connected inside the positioning hole 922. When the user needs to adjust the distance between the handle 1 and the handlebar, the main handle 911 can be pulled towards the handlebar direction according to the requirement and the adjustment button 94 is pressed. The adjustment button 94 drives the positioning block 921 to move towards the spring 95 direction and compress the spring 95. The positioning block 921 is an isosceles triangle block. The positioning block 921 slides out from the positioning hole 922. When reaching the required positioning hole 922, the positioning block 921 will be inserted back into the inside of the positioning hole 922 under the action of the spring 95, thereby realizing the limit fixation of the main handle 911, facilitating the user to quickly adjust the distance between the handle 1 and the handlebar, select the tightness suitable for the user's palm size, and making it more comfortable to hold, and more convenient and safe to use.
