[0014] The utility model will be further described below in conjunction with the accompanying drawings.

[0015] like Figure 1 and Figure 2 As shown, the braking mechanism of the new energy vehicle includes a mounting plate 3 and a brake disc 7, one side of the mounting plate 3 is rotatably connected to the brake disc 7 in the center, and the mounting plate 3 and the brake disc 7 are rotatably connected through a bearing disc 10, a rotatable connecting hole 9 is centrally provided on the mounting plate 3, and the vehicle transmission shaft is rotatably connected through the rotatable connecting hole 9, and a positioning hole fixed to the frame is also provided on the mounting plate 3, and a fixed mounting hole 2 is provided on the brake disc 7 corresponding to the rotatable connecting hole 9, and the vehicle transmission shaft is fixedly connected through the fixed mounting hole 2, and rotates with the transmission shaft, and a driving arm 1 is rotatably connected to the upper part of the mounting plate 3, and the bottom two ends of the driving arm 1 are respectively connected to swing arms 5 through connecting rods 4, and the other end of the swing arm 5 is rotatably connected to the lower part of the mounting plate 3, and a brake pad 6 is fixed on the inner side of the swing arm 5, and the driving arm 1 drives the swing arm 5 to swing through the connecting rod 4, thereby driving the brake pad 6 to clamp the brake disc 7 inward to form a braking effect.

[0016] In order to achieve the synchronous control effect of the two swing arms 5, the driving arm 1 is further an inverted T-shaped structure, with a mounting hole 2 at the top and symmetrically rotating connecting rods 4 at both ends of the bottom. In the process of the driving arm 1 swinging to one side, the two connecting rods 4 rotate one upward and the other downward, and drive the swing arm 5 to rotate inward synchronously, thereby driving the brake pad 6 to form a friction braking effect on the brake disc 7.

[0017] Furthermore, the swing arm 5 is an L-shaped structure, with the top end rotatably connected to the end of the connecting rod 4 away from the driving arm 1, and the bottom ends of the two swing arms 5 are coaxially connected to the bottom of the mounting plate 3, so that the formation distance of the swing arms 5 can be the same. Under the driving action of the connecting rod 4, the two brake pads 6 are synchronously contacted with the brake disc 7 to achieve a good braking effect.

[0018] In order to ensure the braking effect of the brake pad 6, the side of the brake pad 6 facing the brake disc 7 is an arc-shaped structure, which matches the brake disc 7. The brake pad 6 and the brake disc 7 have the same thickness and size, and the brake pad 6 and the brake disc 7 are in contact with a large area, which can achieve a stable and efficient braking effect.

[0019] When the utility model is actually used, the mounting plate 3 is rotatably connected to the transmission shaft and the brake disc 7 is fixedly connected to the transmission shaft through the fixed mounting hole 2 and the rotating mounting hole 2, and rotates with the transmission shaft, and the mounting plate 3 is fixedly connected to the vehicle frame through the positioning hole; the mounting hole 2 on the driving arm 1 is used to connect with the vehicle driving unit, driving the driving arm 1 to swing with the connection point with the mounting plate 3 as the fulcrum, so that one of the two connecting rods 4 flips upward and the other flips downward, thereby driving the swing arm 5 to rotate inward, so that the brake pad 6 fits and presses the brake disc 7 to achieve the braking effect; the overall structure involves fewer components and has a fast response speed, and can be used as an active or auxiliary braking mechanism of the vehicle, thereby improving driving safety.
