Safety lock of remote anti-theft electric vehicle

Abstract

The invention discloses a safety lock of a remote anti-theft electric vehicle, which comprises a lock casing, a clamp-type locking mechanism, a piston drive device and an anti-theft alarm device. The piston drive device is provided with an expandable rigidity piston, the clamp-type locking mechanism comprises a left clamp-type crank arm and a right clamp-type crank arm, and a left positioning pin and a right positioning pin which are matched with the left clamp-type crank arm and the right clamp-type crank arm in a sliding way and are fixedly arranged in the lock casing; one end of the left clamp-type crank arm and one end of the right clamp-type crank arm extend out of the locking casing to clamp a wheel yoke, the other end of the left clamp-type crank arm and the other end of the right clamp-type crank arm are hinged with one end of a left connecting rod and one end of a right connecting rod through a left first hinge shaft and a right first hinge shaft, and the other end of the left connecting rod and the other end of the right connecting rod are hinged to the left T-shaped shaft end and the right T-shaped shaft end of an expandable rigidity piston shaft; a remote signal transmitter controls the electric drive device to enable the expandable rigidity piston shaft to expand back and forth, thereby controlling the clamping or releasing of the wheel yoke by the clamp-type crank arms and achieving the purposes of opening and closing the safety lock of the remote anti-theft electric vehicle. The invention has the advantages of simple structure, stable working, better anti-theft function, and the like.

Description

technical field [0001] The invention belongs to the technical field of anti-theft locks, and relates to a remote-controlled anti-theft electric vehicle lock. Background technique [0002] Existing anti-theft electric vehicle locks have various patterns and different types; but most of them are mechanical locks, which are generally unlocked by keys, but the keys are easy to be copied, and can also be opened by a master key. The safety performance is not high, and the mechanical The lock does not have an alarm function, which gives the car theft a chance to take advantage of, and it is also relatively troublesome to unlock with a key when parking every time and driving. What's more, some troublemakers squeeze glue into the keyhole, so that the electric car cannot be opened, so it is disturbing. [0003] At present, the patent CN200820016981.9 is disclosed in the Chinese patent literature, a remote control electric anti-theft alarm lock, including a lock body, a motor is insta...

Problems solved by technology

[0006] 2. The two lock sleeves lack the main control force. When locking, only relying on the torsion force of a pair of torsion springs centered on the hinge shaft is far from enough

[0007] 3. The most important thing is that there is no power to control the "open" and "close" actions of a pair of lock sleeves; at the same time, there is no device to prevent loosening after locking
