Abstract
The utility model relates to a power-off device, specifically to an emergency power-off device for an electrombile, and belongs to the technical field of vehicle safety means. The emergency power-off device comprises a control body comprising an automatic switch, a fuse and an electromagnetic relay, and a motor controller , a DC converter and a power cell respectively connected with the control body, wherein the negative end of the power cell is connected with the automatic switch, the automatic switch, the fuse and the electromagnetic relay are sequentially connected to each other, and the negative end of the motor controller is connected with the electromagnetic relay. The emergency power-off device is simple in structure and low in cost. When an entire circuit is short circuited, the emergency power-off device ensures the circuit safety of the entire electrombile.
Description
Technical field
The utility model relates to a kind of breaker device, and especially a kind of battery-driven car emergency power-off device belongs to the vehicle security apparatus technical field.
Background technology
Progressively popularization along with green living, comprise that the new-energy automobile of battery-driven car just is being subject to more and more people's favor, compare to conventional truck, the plurality of advantages such as that although battery-driven car has is pollution-free, noiseless, energy savings, but has following defective: along with the prolongation in service life, faults such as short circuit, short circuit of the unavoidable appearance of its circuit causes vehicle to use; Especially during short circuit, the electric pulse of moment very easily produces each electrical equipment in the whole circuit and impacts injury, so that battery-driven car can't normally move, also can cause potential safety hazard when serious.
Therefore, can design a kind of emergency power-off device of electric vehicle to overcome defects, become the technical barrier that those skilled in the art need to be resolved hurrily.
The utility model content
The utility model aims to provide a kind of emergency power-off device for battery-driven car, and it is simple in structure, cheap, can ensure vehicle circuitry safety when whole circuit is short-circuited.
Its technical scheme that adopts is as follows: this battery-driven car emergency power-off device mainly comprises control subject and the electric machine controller that is attached thereto respectively, DC conv, electrokinetic cell, comprise automatic switch, safety plate and electromagnetic relay in the control subject, wherein, the negative terminal of electrokinetic cell is connected with automatic switch, automatic switch, safety plate are connected with electromagnetic relay and are connected, and the negative terminal of electric machine controller is connected with electromagnetic relay.
Compared with prior art, the utlity model has following advantage:
Because automatic switch is connected to the negative pole of electrokinetic cell, when whole circuit was short-circuited, automatic switch can disconnect rapidly, cut off the electricity supply, thereby protected the electrical equipment of whole circuit not burnt; And it is simple in structure, cheap.
Description of drawings
Fig. 1: the structural representation of a kind of battery-driven car emergency power-off device of the present utility model.
Nomenclature: 1, control subject; 2, electric machine controller; 3, electrokinetic cell; 4, DC conv; 5, automatic switch; 6, safety plate; 7, electromagnetic relay.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and example:
An embodiment of the present utility model as shown in Figure 1, electric machine controller 2, DC conv 4, electrokinetic cell 3 that this battery-driven car emergency power-off device mainly comprises control subject 1 and is attached thereto respectively, comprise automatic switch 5, safety plate 6 and electromagnetic relay 7 in the control subject 1, wherein, the negative terminal of electrokinetic cell 3 is connected with automatic switch 5, automatic switch 5, safety plate 6 are connected with electromagnetic relay in turn and are connected, and the negative terminal of electric machine controller 2 is connected with electromagnetic relay 7.
The use procedure of this utility model of brief description: this product is that the negative terminal of electrokinetic cell 3 connects automatic switch 5, connect safety plate 6, the last negative terminal that directly connects electric machine controller 2, when automatic switch 5 conducting, by the control power supply of ignition lock to electromagnetic relay 7, then the adhesive electromagnetic relay 7, and direct electric conduction machine controller 2 is connected with electrokinetic cell 3, thereby effectively realize the emergency power off under the short circuit condition, ensure the safety of the circuit of car load.
The above is illustrated the utility model with way of example, but the utility model is not limited to above-mentioned specific embodiment, and all any change or modification of doing based on the utility model all belong to the claimed scope of the utility model.
