[0002] At present, as people pay more attention to environmental pollution, electric vehicles have become a means of transportation for many people, but in my country, electric vehicles are not uniformly classified as motor vehicles, so there is a clear limit on the maximum speed of electric vehicles, but in use However, there is a problem of modifying the speed limiting device, and it is widespread, and some even become the selling point of electric vehicles, but the modification of the speed limiting device brings great potential safety hazards. With the increase of electric vehicles, the speed of electric vehicles Speeding accidents are also on the rise

Embodiment Construction
[0014] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0015] Such as figure 1 and figure 2 As shown, a motor speed limiting device for electric vehicles includes a motor casing and an electrical box arranged on the inner wall of the motor casing. A cover plate is arranged on the electrical box, and the arc radius of the cover plate is the same as the arc radius of the motor casing. Similarly, the control circuit is set in the electrical box, and after the control circuit is installed in the electrical box, the cover plate and the motor casing are welded together. The control circuit includes a Hall current sensor, a controller, a first switching element, a second switching element and resistor, the Hall current senso...

The device comprises a motor shell and an electric box arranged on the inner wall of the motor shell, the electric box is provided with a cover plate, the radius of the radian of the cover plate is the same as that of the radian of the motor shell, a control circuit is disposed in the electric box, the cover plate and the motor shell are welded together after the control circuit is installed in the electric box, and the control circuit comprises a hall current sensor, a controller, a first switch component, a second switch component and a resistor. The aim of preventing manual change of a speed limiting device of the electric vehicle is achieved.
Description
technical field [0001] The invention relates to a motor speed limiting device for an electric vehicle. Background technique [0002] At present, as people pay more attention to environmental pollution, electric vehicles have become a means of transportation for many people, but in my country, electric vehicles are not uniformly classified as motor vehicles, so there is a clear limit on the maximum speed of electric vehicles, but in use However, there is a problem of modifying the speed limiting device, and it is widespread, and some even become the selling point of electric vehicles, but the modification of the speed limiting device brings great potential safety hazards. With the increase of electric vehicles, the speed of electric vehicles Accidents caused by speeding are also on the rise. Contents of the invention [0003] The purpose of the present invention is to solve the above problems and propose a motor speed limiting device for electric vehicles, so as to realize t...
