Abstract

The utility model belongs to a theft-protection device, particularly relating to a battery burglar alarm of an electric vehicle. A circuit of the alarm comprises a battery T, a switch K, a voice chip COB, a buzzer Q, a direct-current relay J and a 12 to 48V power supply, wherein the connecting relationship of the components is as follows: pins 1 and 2 of the voice chip COB are connected with pins 1 and 2 of the buzzer Q respectively; pin 3 of the voice chip COB is connected with an anode of the battery T; pin 4 of the voice chip COB is connected with one end of the switch K; the other end of the switch K is connected with a cathode of the battery T; pins 5 and 6 of the voice chip COB are connected with pins C1 and C2 of the direct-current relay J respectively; and pins B1 and B2 of the direct-current relay J are connected with each other and 12 to 48V power supplies A and B. The battery burglar alarm of the electric vehicle is applicable to the installation of a battery jar of 12 to 48V electrical vehicle, and can be assembled conveniently and has low cost. When a stealer pulls out the battery jar or cuts off a power supply line, the burglar alarm automatically gives an alarm so as to prompt a vehicle owner and scares away the stealer, thus leading the vehicle owner to avoid economic loss.

Description

The electrocar battery anti-theft device

Technical field

The utility model belongs to anti-joyride device, particularly a kind of electrocar battery anti-theft device.

Background technology

At present, the quantity of the battery-driven car of China is considerably beyond the quantity of bicycle, and battery-driven car is afraid of most is exactly losing of battery, according to incompletely statistics, every day, each city had more than 100 battery to lose approximately, lose battery and promptly equal to lose battery-driven car, bring inconvenience for people's trip, economy also is subjected to massive losses, and on battery-driven car dress annunciator is also arranged, what need when adorning onboard is the voltage of battery of electric vehicle, when battery is dialled following time from car, Car Burglar Alarm does not have the warning effect yet, and the robber steals battery and only needs a few times in second, when annunciator had little time to ring, battery was stolen.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned technical deficiency, and a kind of easy for installation, electrocar battery anti-theft device timely of reporting to the police is provided.

The technical scheme that the utility model technical solution problem adopts is: comprise battery T, K switch, speech chip COB, buzzer phone Q, DC relay J and 12～48V power supply in the circuit of electrocar battery anti-theft device, their annexation is 1,2 pin that 1,2 pin of speech chip COB connect buzzer phone Q respectively, 3 pin of speech chip COB connect the positive pole of battery T, 4 pin of speech chip COB connect an end of K switch, the negative pole of another termination battery T of K switch, 5,6 pin of speech chip COB meet the C of DC relay J respectively ₁, C ₂Pin joins, the B of DC relay J ₁, B ₂Pin joins and meets 12～48V power supply A, B.

The beneficial effects of the utility model are: the electrocar battery anti-theft device is applicable to the storage battery installation of 12～48V battery-driven car, and it is easy for installation, and cost is low, when the burglar dials down storage battery or cuts off power lead, Car Burglar Alarm will auto alarm, reminds the car owner, frightens the robber away, avoids economy to suffer a loss.

Description of drawings

Specify with embodiment below in conjunction with accompanying drawing.

Fig. 1 is electrocar battery anti-theft device schematic circuit diagram.

Among the figure, the T-battery; The K-switch; The COB-speech chip; The Q-buzzer phone; The J-DC relay; A, B-12～48V power supply;

The specific embodiment

Embodiment, with reference to accompanying drawing 1, comprise battery T, K switch, speech chip COB, buzzer phone Q, DC relay J and 12～48V power supply in the circuit of electrocar battery anti-theft device, their annexation is 1,2 pin that 1,2 pin of speech chip COB connect buzzer phone Q respectively, 3 pin of speech chip COB connect the positive pole of battery T, 4 pin of speech chip COB connect an end of K switch, the negative pole of another termination battery T of K switch, and 5,6 pin of speech chip COB meet the C of DC relay J respectively ₁, C ₂Pin joins, the B of DC relay J ₁, B ₂Pin joins and meets 12～48V power supply A, B.

During the electrocar battery anti-theft device is contained in the box; line is received on the battery of battery-driven car, the speech chip COB of Car Burglar Alarm can send instruction when the robber dials battery, and buzzer phone Q sends chimes of doom; play the protection battery and do not stolen effect, K switch can also be controlled with remote controller.
