Description

Technical Field

[0001] This utility model relates to the field of electric vehicle equipment technology, specifically to an improved braking device for electric tricycles. Background Technology

[0002] An electric tricycle is a three-wheeled transport vehicle powered by a battery and driven by an electric motor. It is mainly used for hauling goods or people. The braking device works by using friction to convert the vehicle's kinetic energy into heat energy, thereby slowing down or stopping the vehicle.

[0003] For example, an electric tricycle braking system with announcement number "CN212401470U" shortens the brake cable length and reduces the number of turns through a linkage structure between the brake lever and the brake cable. This reduces the resistance of the brake cable itself and the amount of deformation on the brake cable, resulting in better and more stable braking performance, and the brake system layout is neater. However, when replacing or installing the brake cable, the old brake cable needs to be removed, and then the new brake cable needs to be installed. When fixing the brake cable, the tightness of the brake cable needs to be adjusted. Manually adjusting the tightness requires fixing the brake cable multiple times, removing the brake cable according to the tightness, and then adjusting it again. The operation is relatively cumbersome and affects work efficiency. Utility Model Content

[0004] The purpose of this invention is to solve the problem that manually adjusting the tightness of the brake cable requires repeatedly fixing the brake cable, removing the brake cable according to the tightness, and then adjusting it again, which is cumbersome and affects work efficiency. Therefore, an improved braking device for electric tricycles is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design an improved braking device for an electric tricycle, including a pedal and a foot lever. The pedal is fixedly connected to one end of the foot lever, and a connecting block is fixedly connected to the other end of the foot lever. The connecting block is movably connected to a fixed block via a pin. The inner wall of the connecting block is slidably connected to a cylinder. A pull rod is fixedly connected to the end of the cylinder, and a brake cable adjustment structure is provided on the left side of the pull rod.

[0007] Preferably, the brake cable adjustment structure includes a housing, with two clamping plates fixedly connected to the inner wall of the housing. Both clamping plates are threadedly connected to a first bolt. A threaded sleeve is fixedly connected to the right end of the housing, and the threaded sleeve is threadedly connected to a second bolt. The second bolt is rotatably connected to a bending plate via a bearing.

[0008] Preferably, the lower end of the housing is slidably connected to the curved plate, and the lower end of the curved plate is slidably connected to the body of the electric tricycle.

[0009] Preferably, the inner walls of the two clamps abut against the brake line, and a limiting piece is fixedly connected to the middle of the brake line.

[0010] Preferably, a limiting sleeve is fitted onto the outer wall of the brake cable, and the end of the limiting sleeve is connected to the rear wheel hub of the electric tricycle.

[0011] This utility model proposes an improved braking device for electric tricycles. The advantages are as follows: Through the cooperation of a brake cable adjustment component and manual operation, the old brake cable is first removed, then the new brake cable is cut to the required length. The brake cable is then passed through a limiting sleeve, and one end is fixed to the brake pad. Rotating the second bolt moves the threaded sleeve to the left, which in turn moves the housing. The other end of the brake cable is then inserted into the housing and between two clamping plates. Rotating the first bolt clamps the brake cable, and then rotating the second bolt in the opposite direction moves the housing to the right, tightening the brake cable and completing the adjustment of its tension. This allows for the installation of a brake cable of approximate length into the device before adjusting its tension directly, eliminating the need to repeatedly remove and adjust the brake cable, thus improving work efficiency.
