Abstract
A speed limiter for an electric vehicle comprises an electric motor (1), wherein the electric motor (1) is connected with a control module (4), a speedometer (2) is connected with a comparison module (3), the comparison module (3) is connected with the electric motor (1) and composed of a computing circuit, and the control module (4) is composed of a relay and a control chip. In the speed limiter, the electric motor is connected with the control module, the speedometer is connected with the comparison module, the comparison module is connected with the electric motor and is composed of the computing circuit, and the control module is composed of the relay and the control chip, so that when the electric vehicle overspeeds, the comparison module sends a signal to the control module, the control module controls a battery to supply power to the electric motor intermittently, and continuous power supply is not regained until the speed is within a safe range, which can effectively prevent speeding and achieve safety and reliability.
Description
Technical field
The utility model relates to a kind of velocity limiter, relates in particular to a kind of battery-driven car velocity limiter.
Background technology
Battery-driven car uses more and more general at present, become the important tool of people's Green Travel, but existing battery-driven car is easy on road drive over the speed limit, and has greatly potential safety hazard, lack a kind of velocity limiter of battery-driven car moving velocity that can limit to prevent the driving over the speed limit minimizing traffic accident.
Summary of the invention
The purpose of this utility model is to lack defective and the deficiency of limitting check piece at existing battery-driven car, now provides a kind of simple in structure, cheap, and battery-driven car velocity limiter very easily is installed.
For achieving the above object, technical solution of the present utility model is: the battery-driven car velocity limiter, comprise: electrical motor, it is characterized in that: described electrical motor is connected with control module, speed gauge is connected with comparison module, comparison module is connected with electrical motor, and comparison module is made of arithmetical circuit, and control module is made of relay and control chip.
Described speed is counted the electromagnetic type speed gauge.
The beneficial effects of the utility model are: electrical motor is connected with control module, speed gauge is connected with comparison module, comparison module is connected with electrical motor, comparison module is made of arithmetical circuit, and control module is made of relay and control chip, and comparison module is issued control module with signal when driving over the speed limit, control module will be controlled battery phase electrical motor intermittent power supply, in speed is in safe range, just recover power supply continuously, can effectively prevent to drive over the speed limit, safe and reliable.
