Abstract
The utility model discloses an automatic protection controller for electric vehicles, which comprises a case body and a circuit that is composed of a speed regulation signal stage, an intelligent modulation stage, a power propeller stage and a drive stage; moreover, the circuit is also composed of an overload protection circuit; the input ends of the overload protection circuit are respectively connected with the speed regulation signal stage and the power source; the output ends are respectively linked to the input ends and outputs to the drive stage. In case of transfinite overload or long-period climbing in servicing, the driver can screw a rotary handle switch to the maximum to launch signals and make the input ends and output ends of the drive stage in direct short circuit; after the protection controller enters a flat road or is unloaded, the rotary handle will be rotated to launch a signal to cut off the short circuit connection between the input end and the output end on the drive stage, so as to recover the normal running status of the controller, Therefore, the controller has the advantages of not easy to heat, long service life and safe and reliable operation.
Description
Technical field
The utility model belongs to the control technology for electric motor car field, specifically relates to a kind of automatic protection controller.
Background technology
Controller is the core component of battery-driven car electric system, and it mainly is to determine driving states according to various signals, and the rotative speed of control motor carries out actv. detecting and protection to the car load electric system; Though existing controller for electric vehicle is provided with overload protecting circuit mostly, complex structure, and at sudden lading or meet the hill path when climbing for a long time; the controller field effect transistor is easily generated heat and is burnt; cause controller to damage, the battery-driven car get out of hand influences traffic safety.
Summary of the invention
The technical problems to be solved in the utility model provides a kind ofly protects controller automatically at complex road condition and when overload defencive function battery-driven car strong and simple in structure that transfinites.
For solving the problems of the technologies described above; the utility model comprise box body and be located at wherein promote the circuit that level, driver stage are formed by speed-regulating signal level, intelligent modulation level, power; its constructional feature is also to comprise overload protecting circuit in the described circuit; the input end of this overload protecting circuit is connected with power supply with the speed-regulating signal level respectively, and its mouth can be connected with output with the input end of driver stage respectively.
Described overload protecting circuit comprises relay, the coil of this relay be connected on the power supply after micro-switch is connected, the open contact of relay is connected between the input end and mouth of driver stage.
Micro-switch is an open type, and this micro-switch is located at the handle below, and handle is provided with the shelves fork.
The beneficial effects of the utility model are: because the input end of this overload protecting circuit is connected with power supply with the speed-regulating signal level respectively; its mouth can be connected with mouth with the driver stage input end respectively; transship or long-time climbing when transfiniting in the driving; when being threaded to maximum, just sends by the handle switch signal; with driver stage input end and mouth direct short-circuit conducting; the protection controller; after entering level road or unloading; the handle revolution is also sent signal; the short circuit that disconnects driver stage input end and mouth is connected, and recovers the normal controller running state, so controller is difficult for heating; long service life, safe and reliable to operation.
