Abstract
The utility model aims at providing a power switch control circuit for an electric motor car, and the power switch control circuit comprises an electric door lock connected with a power supply, and a load circuit. An electronic switch is arranged between the power supply and the load circuit in the power switch control circuit for the electric motor car; the electric door lock is connected with an amplifying circuit which is also connected with the electronic switch. By adopting the structure, the power switch control circuit can control the on-off of heavy current with weaker current; the closure of the electric door lock can disconnect the connection between a battery cell and the load circuit, thereby avoiding the electricity leakage of the power supply, saving power and ensuring the absolute safety of the electric motor car when in parking.
Description
Technical field
The utility model relates to the control circuit of battery-driven car, relates in particular to the power on-off control circuit of battery-driven car.
Background technology
Along with social development, battery-driven car enters each household family in big strides, becomes a kind of indispensable vehicle.Even but all also there is a great potential safety hazard in present battery-driven car more than 80%---has pulled out the electric door lock pass to key the back of stopping, and the power supply on the storage battery still is connected on the load circuit.This is that a defective that exists is gone up in existing vehicle electric circuitry design. as shown in Figure 1, and the signal power source that electric door lock of the prior art can only be controlled illumination, loudspeaker and remove power circuit.If fully charged battery-driven car does not travel for a long time, power supply can cause the battery-driven car operating range to shorten, even can not travel through the load circuit discharge, needs could use after the charging again.Just in case battery-driven car internal wetted or electric leakage, short circuited situation occur, battery-driven car just might be smoldered, spontaneous combustion even blast, and these accidents are also of common occurrence in news.Also there is a kind of battery-driven car on battery power, to be provided with battery isolator control, can PTO Power Take Off.But be to use very inconvenience, chaufeur is opened the battery-driven car cushion with key after must closing electric door lock again, opens cushion, hand is put in source switch is closed.Chaufeur has no time to close this switch at all under some emergencies, and careless driver also can be forgotten and closes this switch.Such design does not have the effect of protection yet.
The utility model content
The purpose of this utility model provides a kind of power on-off control circuit of battery-driven car, control the break-make of big electric current with less current, can cut off being connected of storage battery and load circuit after electric door lock is closed, stopped the electric leakage of power supply, energy savings has guaranteed battery-driven car being perfectly safe when stopping.
For reaching described purpose, comprise the electric door lock that is connected on the power supply, and load circuit, it is characterized in that: be provided with electronic switch between power supply and the load circuit in the power on-off control circuit of described battery-driven car, described electric door lock is connecting amplifying circuit, and amplifying circuit is also connecting electronic switch.
Further, be connected with protective circuit on described amplifying circuit and the electronic switch.In the time of like this can abnormal condition appear in curtage in battery-driven car, close electronic switch immediately, cut off the power supply on the load circuit, the safety when having ensured the battery-driven car driving.Described protective circuit generally is made up of electronic control circuit..
Owing to adopted described technical scheme, connect electric door lock, power supply signal amplifies through amplifying circuit, drives the electronic switch action, connects the power supply of load circuit; When electric door lock was closed, electronic switch was also closed, and power supply and load circuit disconnect like this, had guaranteed the safety of the battery-driven car under the parking condition.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the power on-off control circuit structured flowchart of battery-driven car in the prior art.
Fig. 2 is the power on-off control circuit structured flowchart of a kind of battery-driven car of the utility model.
The specific embodiment
As shown in Figure 2, a kind of power on-off control circuit of battery-driven car, comprise the electric door lock that is connected on the power supply, and load circuit, also be provided with electronic switch in the power on-off control circuit of described battery-driven car between storage battery and the load circuit, described electric door lock is connecting amplifying circuit, and amplifying circuit is also connecting electronic switch.
Be connected with protective circuit on described amplifying circuit and the electronic switch, described protective circuit is made up of electronic control circuit usually.Such structure can further be guaranteed the safety and stablization of battery-driven car.
When battery-driven car of the present utility model is equipped with in use, with key electric door lock to be opened earlier, signal power source (little electric current) is amplified through amplifying circuit, drives electronic switch closes.Load circuit is started working.The driver can use battery-driven car to travel.
When the cruising process, in case voltage or electric current occur unusually in the circuit, protective circuit is action immediately just, closes electronic switch, cuts off the electricity supply, and plays the effect of safety guard-safeguard.
When battery-driven car does not use, close electric door lock with key, electric door lock control this moment electronic switch disconnects.Cut off being connected of power supply and load circuit.Such disconnect mode simple and fast has really realized controlling with little electric current the purpose of the big electric current of break-make.Extract the electric door lock key and just thoroughly cut off being connected of power supply and load circuit, stopped the electric leakage of power supply, energy savings, and the safety when having guaranteed the battery-driven car parking are ensured customer's personal safety as well as the property safety.Battery-driven car especially in the process of sea-freight, is in the strong environment of humidity, corrosive property in transportation, and the power on-off control circuit of a kind of battery-driven car of the utility model can effectively be avoided the generation of accidents such as spontaneous combustion, blast.
