Energy-saving automatically-warning battery theft-preventing alarm device and control method thereof

Abstract

The invention discloses an energy-saving automatically-warning battery theft-preventing alarm device for an electric vehicle and a control method thereof. An alarm main device of the alarm device except for a permanent magnet is installed in a battery box, and a normally closed dry-reed pipe and a normally opened dry-reed pipe which are connected in parallel and are freely arranged and combined are installed on the inner wall of a box body of the battery box on the contact surface between the battery box and a battery groove; a switch 9 is installed on the box body on the contact surface between the battery box and the battery groove; and the permanent magnet is installed on the inner wall of the battery groove and corresponds to the normally closed dry-reed pipe. The control method is achieved as follows: when the battery box is placed into the battery groove and the alarm sound of a loudspeaker is turned off, a power supply of the alarm main device is cut off, and the energy-saving automatically-warning battery theft-preventing alarm device is in a warning state; when a thief steals the battery box, the power supply of the alarm main device is switched on and sends the alarm sound when the battery box is separated from the battery groove, and the alarm sound can be withdrawn after the alarm main device receives a cipher key of a cipher transmitter. The invention has flexiblecontrol and convenient use.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, in particular to an anti-theft alarm device for electric vehicle batteries. Background technique [0002] Compared with bicycles, electric bicycles are faster, labor-saving, and safer than motorcycles, and have become a favorite means of transportation for the urban and rural masses in my country. Electric bicycles are equipped with anti-theft alarms for automatic vehicles, but users often forget to set up defenses. Although users can lock the car body with mechanical locks, since the battery is placed in the battery box, the battery box is placed in the battery box of the electric bicycle. The slot, its fixation and anti-theft, generally adopts ordinary locks. As we all know, the anti-theft effect is poor. Often, only ordinary criminal tools can easily destroy the lock of the lock battery box, and easily steal the battery, which is the battery of the electric bicycle. As expensive con...

Electric bicycles are equipped with anti-theft alarms for automatic vehicles, but users often forget to set up defenses. Although users can lock the car body with mechanical locks, since the battery is placed in the battery box, the battery box is placed in the battery box of the electric bicycle. The slot, its fixation and anti-theft, generally adopts ordinary locks. As we all know, the anti-theft effect is poor. Often, only ordinary criminal tools can easily destroy the lock of the lock battery box, and easily steal the battery, which is the battery of the electric bicycle. Valuable consumable accessories, so many thieves are targeting electric bicycle batteries, resulting in frequent theft of electric bicycle batteries

Although there are a lot of anti-theft patents that mechanically reinforce the battery box at present, as the publication number is CN101314323A "a kind of electric vehicle battery anti-theft bolt", the publication number is CN201099167y "crawler type electric bicycle battery anti-theft device", the publication number is CN201214455y "Electric vehicle battery anti-theft device" all play the role of battery anti-theft, but it is very troublesome for users to take out the battery, and it affects the appearance of the whole vehicle

At present, there are many patents for electronic battery anti-theft alarm devices for electric vehicles, such as the "electric vehicle battery anti-theft alarm" with the publication number CN201201573y, which to some extent plays the role of electric vehicle battery anti-theft alarms, but has disadvantages: first, the user needs The anti-theft alarm function can only be achieved by setting the alarm in advance, but when the user forgets the alarm setting, the battery anti-theft alarm function cannot be achieved; second, the battery anti-theft alarm is usually in the power-on state and does not save energy.
