Abstract
The invention relates to a battery cell anti-theft device capable of giving off an alarm simultaneously when an illegal person cuts off the power supply of a battery cell. A circuit of the device is formed by a relay, a power supply, an alarm and a switch which are connected in order. The power supply of the battery cell is used to power the relay; and normally closed contacts of the relay are in a disconnected state. When the illegal person cuts off any of the power leads of the battery cell, the relay stops working and the normally closed contacts are attracted together so as to turn on the power supply of the alarm; and consequently the alarm whistles to protect the battery cell. The battery cell antitheft device can give off the alarm at the moment that the power supply of the battery cell is cut off. The battery cell antitheft device has low cost, a simple structure and convenient production, and can be widely applied to the theft protection of the battery cell.
Description
Technical field:
The burglary-resisting installation that the present invention gives the alarm after being cut off for battery power.
Background technology:
At present, known lorry storage battery all is exposed to the car body outside.Be easy to storage battery be unloaded from lorry, thereby cause economic loss for numerous car owners by the undesirable.
Summary of the invention:
For the connecting line that does not allow the undesirable cut off storage battery and car body is easily stolen storage battery, the present invention had both provided as the undesirable and had cut off any power lead, this device is started working and is sounded the alarm, thereby plays the warning effect, and battery safety is guaranteed.
The technical solution adopted for the present invention to solve the technical problems is: because the lorry storage battery is the 12V DC voltage, so use a 12V single flow relay, utilize relay normally closed contact control alarm work, the normally closed contact two ends be connected to an end of another power supply and switch, and warning horn on, the power supply of storage battery is connected on the relay two ends respectively, and is middle by a switch control (the shared same switch of this switch and warning horn).When switch closure, battery power is connected, and the relay normally closed contact disconnects does not report to the police, and warning circuit is connected in the relay normally closed contact adhesive of not working when cutting off the battery power line, and alarm is sent and rung, and plays the warning effect.
Beneficial effect of the present invention: can give the alarm in the moment of cutting off battery power, cost of the present invention is low, and simple in structure being convenient to produced, and can be widely used in storage battery antitheft.
Description of drawings:
The present invention is further described below in conjunction with accompanying drawing:
Fig. 1 is circuit theory diagrams of the present invention.
Among Fig. 1: 1 warning horn, 2 power supplys, 3 relays, 4 switches, 5 storage batterys
Embodiment:
Primary structure of the present invention comprises: relay 3, power supply 2, alarm 1, switch 4 and storage battery 5, relay, power supply, alarm, switch are linked in sequence and form the loop, the power supply of storage battery 5 is relay 3 power supplies, make the normally closed contact of relay 3 be in off-state, when cutting off battery power, storage battery stops relay 3 power supplies, the adhesive of relay normally closed contact, and warning horn is connected.
Claims (1)
- A kind ofly can when cutting off battery power, the undesirable send the anti-theft equipment for battery of warning, be linked in sequence by relay, power supply, alarm, switch, it is characterized in that: the power supply of storage battery is the relay power supply, make the normally closed contact of relay be in off-state, when cutting off battery power, storage battery stops the relay power supply, the adhesive of relay normally closed contact, and warning horn is connected.
