Abstract
The utility model relates to an electric vehicle control circuit, in particular to an electric vehicle circuit with automatic restoration function, wherein an overcurrent electronic protection element is connected in the circuit of a power supply, which is connected with a control circuit, and is a self-restoring fuse. The electric vehicle circuit has the beneficial effects that when the circuit occurs short-circuit or overload, the current is rapidly disconnected, thereby rapidly and accurately limiting and protecting the circuit, the temperature is reduced after eliminating the power-off and faults, the self-restoring fuse can restore the normal state, which does not need to replace the fuse by operators.
Description
Technical field
The utility model relates to a kind of electric vehicle control circuit, specifically is a kind of vehicle electric circuitry with self-recovering function.
Background technology
Along with improving constantly of people's living standard, battery-driven car comprises that Electrical Bicycle, battery-operated motor cycle and electro-tricycle are by being applied in the daily life more and more widely.Common electric vehicle control circuit comprises motor, with motor bonded assembly control circuit with to the power supply of total system power supply.For improving its overcurrent protection function, what have is connected with a general insurance silk in power supply and control circuit bonded assembly circuit, once overburden or because of other reasons makes the electric current in the electric power loop big, wire fuse then fuses.Its defective is must change the wire fuse battery-driven car and just can travel after having got rid of fault.If wire fuse is not prepared at the scene in advance, battery-driven car then can't start, and brings inconvenience to use.
Summary of the invention
For solving the above-mentioned deficiency of prior art, the utility model provides a kind of vehicle electric circuitry with self-recovering function.
The present invention realizes with following technical scheme: a kind of vehicle electric circuitry with self-recovering function; comprise motor, with motor bonded assembly control circuit with to the power supply of total system power supply; it is characterized in that; be connected with an overcurrent Electronic Protection element in power supply and control circuit bonded assembly circuit, described overcurrent Electronic Protection element is a resettable fuse.
Owing to adopt technique scheme; the beneficial effects of the utility model are: when circuit is short-circuited or transships; the big electric current of resettable fuse of flowing through makes its temperature build-up; when reaching Tc; the in-to-in electrically conductive links is change of snowslide attitude or fracture; wire fuse is phase step type and adjourns high-impedance state; electric current is by rapid pinch off; thereby circuit is carried out fast, limit accurately and protect, its small electric current makes wire fuse be in guard mode always; behind outage and trouble removal; its drop in temperature, resettable fuse reverts to normal condition, need not manually more to renew wire fuse.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the utility model electricity functional block diagram.
Among the figure: 1, motor, 2, control circuit, 2-1, signal deteching circuit, 2-2, driving circuit, 2-3, high-power FET, 2-4, circuit for controlling motor, 3, motor, 4, resettable fuse.
The specific embodiment
Embodiment as shown in drawings, the vehicle electric circuitry with self-recovering function are by motor 3, form with motor bonded assembly control circuit 2 with to the power supply 1 of total system power supply.Control circuit in the frame of broken lines is by circuit for controlling motor 2-4, and high-power FET 2-3, driving circuit 2-2, signal deteching circuit 2-1 form.In power supply and control circuit bonded assembly circuit, be connected with an overcurrent Electronic Protection element resettable fuse 4.Aborning, can be contained in resettable fuse 4 on the power lead in the battery-driven car wire harness being connected of convenient like this and entire circuit.
