Detailed Description

The invention will be further elucidated with reference to the drawing.

As shown in fig. 1 and 2, the battery anti-theft device of the electric tricycle comprises a seat 1 and a box body 2 for placing a battery, wherein the box body 2 is located at the lower part of the seat 1, a lock hook 3 is arranged on the seat 1, and a clamping groove 4 and a lock 5 are arranged on the corresponding box body 2, the lock 5 is an existing mechanical lock, namely, the lock hook 3 is locked after entering the clamping groove 4, the lock hook 3 can be pulled after a key is rotated, the structure of the lock 5 is not introduced here, and the clamping groove 4 can also be understood as a lock hole of the existing lock 5.

In addition, the cross sections of the clamping groove 4 and the locking hook 3 are rectangular, an electromagnet 6 is arranged on the inner wall of one side, opposite to the lockset 5, in the clamping groove 4, the electromagnet 6 can adsorb the locking hook 3 after being electrified, and in addition, a control module is arranged on the box body 2 and comprises a power supply module 7, a single chip microcomputer 8, a fingerprint identifier 9, a relay 10 and a digital-to-analog converter 11. The power module 7 is connected with a battery pack in the box body 2 through a circuit to supply power, and the singlechip 8 is connected with the power module 7; the fingerprint recognizer 9 is installed on the outer surface of the box body 2 and is connected with the single chip microcomputer 8, and the electromagnet 6 is connected with the single chip microcomputer 8 after being connected with the relay 10 and the digital-to-analog converter 11. The singlechip 8 of this application is AT89S51 singlechip.

The singlechip 8 receives the signal of the fingerprint recognizer 9, converts the digital signal into an analog signal and transmits the analog signal to the relay 10, and the magnetic force of the electromagnet 6 is controlled by controlling the on-off of the relay 10. After the electric tricycle owner passes through fingerprint identification, 6 outage degaussing of singlechip 8 control electro-magnet, latch hook 3 loses the adsorption affinity, then can unblank with the key. If not the car owner, in time adopt other keys to open tool to lock 5, still can not open because latch hook 3 is adsorbed by electro-magnet 6, further guaranteed the safety of group battery, also make things convenient for the car owner to unblank.

The component low price that above-mentioned control module adopted, small in size is convenient for install, compares in motor drive's intelligent lock structurally simpler, and traditional mechanical lock has in addition realized the duplicate protection of box and group battery, and the theftproof performance is more superior.

In addition, in order to facilitate the unlocking of the vehicle owner, another circuit is additionally arranged on the single chip microcomputer 8 to be connected with the remote control key of the electric vehicle of the vehicle owner, the connection mode is the prior art, and the connection mode is not repeated. The remote control key of the electric vehicle and the fingerprint recognizer 9 are parallel circuits, and both can independently transmit signals to the single chip microcomputer 8 to control the electromagnet 6.

Because the opening frequency of box 2 is low, only open when changing battery and battery damage, so in order to avoid because the damage of group battery can't be for power module 7 power supply, so power module 7 selects the battery, and set up USB interface 12 on the battery, and the interface of USB interface 12 is located the surface of box 2, be connected with external power, from this, under the circumstances that the group battery damaged, there is self electric quantity to use inside power module 7, can insert outside cell-phone or portable power source to charge after self electric quantity exhausts, the problem that box 2 can't normally open under the circumstances that the group battery damaged has been avoided.

In order to guarantee the effective operation of control module, guarantee that it has the electricity always, it is connected with singlechip 8 to increase to set up bee calling organ 13 in the control module, and singlechip 8 has the function of monitoring the electric quantity, and for current technique, can send a signal to bee calling organ 13 when singlechip 8 monitors the electric quantity not enough, and bee calling organ 13 makes a sound and reminds that the electric quantity in the car owner control module is not enough, need charge for the battery or overhaul the battery, guarantees that it does not have the damage.

Since the fingerprint recognizer 9 is located on the outer surface of the case 2 for a long time, in order to maintain the sensitivity and prevent dust accumulation from affecting the performance of the fingerprint recognizer 9, an openable dust cover (not shown) is arranged on the case 2 at the position of the fingerprint recognizer 9, and in addition, the dust cover can also shield the USB interface 12. The dust cover can select transparent dust cover, conveniently observes.

In order to ensure the safety of the control module, a mounting case (not shown) is provided inside the housing 2, and the components of the molded module are fixed in the case with an opening at one end facing the external opening of the housing 2.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
