Fig. 1-3 are schematic structural diagrams of a brake lever assembly according to an embodiment of the present invention, and fig. 4 is a schematic partial enlarged structural diagram at a in fig. 2. As shown in fig. 1-4, the brake lever assembly of the embodiment of the present invention includes a mounting seat 1 and a brake lever 2, wherein the brake lever 2 includes a connecting portion 21, an operating portion 22 and a reset component. The mounting seat 1 is fixed to the handlebar 7, the connecting portion 21 is rotatably connected to the mounting seat 1 about a first axis, and the operating portion 22 is rotatably connected to the connecting portion 21 about a second axis, wherein the first axis is non-parallel to the second axis, and preferably, the first axis and the second axis are perpendicular. Both ends of the reset member are connected to the operation portion 22 and the connection portion 21, respectively, and the reset member is used to reset the operation portion 22. The connecting part 21 is also used for connecting with the stay wire 3, and the stay wire 3 can be driven to move by operating the brake lever 2, thereby controlling the device connected with the stay wire 3.
Since the brake lever 2 is usually impacted with the foreign object at the lower end of the brake lever 2 when the vehicle falls down and collides with the ground or other objects, the brake lever 2 receives an upward impact force, and thus the second axis may be disposed substantially parallel to the ground or may be inclined with respect to the ground. Thus, when the lever 2 collides with the ground, the operating portion 22 can be rotated in the second axial first direction DIR 1. The operating portion 22 has a first end connected to the connecting portion 21 and a second end, and the first direction DIR1 is a direction in which the second end of the operating portion 22 moves upward relative to the connecting portion 21, so that the brake lever 2 can be prevented from being broken due to a hard impact with the ground.
The whole brake lever 2 can rotate around the first shaft to pull the pull wire 3 connected with the connecting part 21 to move, so that the components connected with the pull wire 3 are controlled to perform corresponding actions. The first shaft connecting portion 21 and the mounting base 1 can be connected through the second rotating shaft 11, the second rotating shaft 11 is arranged along the first shaft, the first shaft is not parallel to the second shaft, preferably, the first shaft is substantially perpendicular to the second shaft, and when a user operates the brake lever 2, the operating portion 22 and the connecting portion 21 are prevented from rotating relatively, so that normal operation of the user is affected, and a braking effect is affected. Depending on the operating habits of the user, the handlebar 7 may be generally substantially parallel to the ground, and the first axis may be disposed substantially perpendicular to the ground.
The connecting portion 21 may have a first groove in which a first end of the operating portion 22 may be disposed. The first end portion and the connecting portion 21 may be connected by a first rotating shaft 24, whereby the operating portion 22 may rotate relative to the connecting portion 21 about the first rotating shaft 24.

The first torsion spring 23 can be sleeved on the first rotating shaft 24 and arranged in the first groove, so that the first torsion spring 23 can be prevented from falling off, and the smoothness of the appearance of the brake lever 2 is improved.
When the operating portion 22 is rotated in the second axial first direction DIR1, the first end portion of the operating portion 22 pushes the first end 231 of the first torsion spring 23 to move in a direction approaching the connecting portion 21, and the distance between the first end 231 and the second end 232 of the torsion spring is shortened, that is, the first torsion spring 23 is torsionally wound. When the vehicle is lifted and the brake lever 2 is away from the ground, the first torsion spring 23 is twisted and restored to the initial state due to the reduction or the removal of the external force applied to the first torsion spring 23, so that the first end 231 moves away from the second end 232, and the operating part 22 is pushed to be reset.
In another alternative embodiment, the reset component may be a first tension spring, and two ends of the first tension spring are fixedly connected with the operation portion 22 and the connection portion 21, respectively. The first tension spring may be disposed above or below the brake lever 2, and for example, when the operating portion 22 is rotated in the first direction DIR1, the distance between both ends of the first tension spring is increased and the first tension spring is stretched when the first tension spring is disposed below the brake lever 2. When the vehicle is lifted and the brake lever 2 is away from the ground, the first torsion spring 23 is restored to the initial state due to the reduction or the removal of the external force applied to the first torsion spring, and the operating portion 22 is pulled to rotate and reset in the second direction.

In an alternative embodiment, as shown in FIG. 5, the first end of the operating portion 22 may have a cambered surface 221, and the distance from the cambered surface 221 to the first axis should be no greater than the distance from the lower edge of the third sidewall 213 to the first axis, i.e., R ≦ L1, so that the operating portion 22 can smoothly rotate from the first position about the second axis in the first direction DIR1, achieving good cushioning. The first end portion may further have a slope contacting the arc surface 221, when the operation portion 22 rotates from the first position to the second direction, since a distance from a point on the slope to the second axis is greater than a distance from a lower edge of the third sidewall 213 to the first axis, that is, L2 is greater than or equal to L1, the lower edge of the third sidewall 213 blocks the operation portion 22 from rotating to the second direction, and the operation portion 22 is prevented from falling down due to gravity and affecting the operation of the user.
