[0040] The working principle of the handle inner core of the utility model is as follows: when used as an electric vehicle;

[0041] When starting: turn on the power of the electric vehicle, the positive and negative power pins of the Hall sensor will get a 5V working power supply provided by the controller (on-board). When we rotate the handle, the position and direction of the arc magnet fixed on the sleeve structure changes, and the direction of the magnetic field sensed by the linear Hall changes from weak to strong. The Hall output end will output a changing voltage of 1-4.2V. Since this voltage is low, it cannot directly drive the motor. This voltage is provided to the operational amplifier of the controller for comparison with the set value, and a voltage value is output according to the comparison result to drive the field effect tube. The field effect tube is connected to the power supply, and the field effect tube is turned on to output voltage to drive the electric vehicle motor to rotate.

[0042] When stopping: loosen the sleeve structure 1, under the action of spring 1, the arc magnet resets, the magnetic field force weakens, the Hall output voltage drops below 1V, the field effect tube is cut off and there is no output voltage, and the motor stops. This is the speed control principle of the speed control handle to control the start and stop of the electric vehicle.

[0043] The handle inner cores described in the first and second embodiments of the present invention have the same principle and achieve the same function.

[0044] The inner core of the handlebar of the utility model is suitable for electric vehicles. The sleeve structure 1 and the sleeve structure 2 are designed so that a matching electric heating handlebar can be installed, so that the handlebar on the vehicle has a heating function.

Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
