[0001] The utility model relates to the technical field of electric motorcycles, in particular to a brake control mechanism for an electric three-wheeled motorcycle. Background Art

[0002] An electric motorcycle is a type of electric vehicle that uses a battery to drive the motor. The electric drive and control system consists of a drive motor, a power supply, and a motor speed control device. The other devices of an electric motorcycle are basically the same as those of an internal combustion engine. The types are divided into electric light motorcycles and electric ordinary motorcycles according to the maximum speed or motor power. The components of an electric motorcycle include: an electric drive and control system, mechanical systems such as a drive force transmission, and a brake control mechanism.

[0003] The brake control mechanism usually includes an oil pump and a brake handle. When the user squeezes the brake handle, the piston of the oil pump is pushed. The piston pushes the oil and then pushes the brake pad to brake. However, the brake control mechanism in the prior art is sometimes not sensitive and sometimes too sensitive, which brings hidden dangers to safety. Therefore, we have introduced a brake control mechanism for an electric three-wheeled motorcycle. Utility Model Content

[0013] The brake control mechanism of the electric three-wheeled motorcycle is provided with a brake handle, a top block, a piston, an oil pump, a movable connecting piece, a rotating wheel, a sliding rod, a strip plate, a screw rod and an anti-skid groove. The rotating wheel is convenient for rotating the screw rod, and the rotating wheel drives the screw rod to rotate. The anti-skid groove increases the friction of the rotating wheel, and the screw rod drives the strip plate to move. The strip plate drives the top block to move through the sliding rod, and then the distance between the top block and the piston is adjusted, so that the sensitivity of the brake control mechanism can be adjusted according to the needs of the user.
