Novel magnetic burglar alarm applicable to lock of motorcycle and electric vehicle

Abstract

Disclosed is a novel magnetic burglar alarm applicable to a lock of a motorcycle and an electric vehicle. A lock bracket is provided with a rotary plate, a shutter rotating plate, a shift block, a lock catch A and a lock catch B. The shutter rotating plate swings to expose a key hole, the shift block swings in transmission of a shift block part, the lock catch A locks the shift block under the action of a reset part A after swinging, and a key transmission slider inserted into the rotary plate moves outwards to overcome the action force of a reset part B, so that the lock catch B is locked. The key is rotated to drive the slider to overcome the action of the reset part A, so that the lock catch A unlocks the shift block, and the shift block slightly rotates under the action of a reset part C and is locked by the lock catch B. the shift block slightly rotating stops the lock catch A from being locked again, the key is pulled out and the lock catch B resets and unlocks the shift block. The shift block is reset and drives the shift block part to swing, so that a stop portion shades the key hole. The key is pulled out after ignition and the shutter rotating plate is automatically closed. Thus, potential safety hazards caused by forgetting to turn off the shutter rotating plate manually are reduced. Besides, the novel magnetic burglar alarm is reasonable in structural design, convenient and practical.

Description

[0001] technical field [0002] The invention relates to a novel magnetic anti-theft device, in particular to a novel magnetic anti-theft device suitable for motorcycle and electric vehicle locks. Background technique [0003] Magnetic anti-theft lock (referring to CN203201275U) is widely used in motorcycles and electric vehicles, and has good anti-theft effect. A magnetic device is provided between the shutter rotating plate and the lock seat, and is generally provided on the key to match the magnetic device. The magnetic column is used to unlock the shutter rotating plate and the lock seat. After unlocking, the shutter rotating plate can be rotated freely. At present, the magnetic anti-theft devices suitable for motorcycles and electric vehicle locks all use manual opening and closing of the shutter rotating plate. Insert the key into the key hole, the shutter turn plate will cover the key hole after closing, and play a role in anti-theft, but users often forget to close t...

[0003] Magnetic anti-theft lock (referring to CN203201275U) is widely used in motorcycles and electric vehicles, and has good anti-theft effect. A magnetic device is provided between the shutter rotating plate and the lock seat, and is generally provided on the key to match the magnetic device. The magnetic column is used to unlock the shutter rotating plate and the lock seat. After unlocking, the shutter rotating plate can be rotated freely. At present, the magnetic anti-theft devices suitable for motorcycles and electric vehicle locks all use manual opening and closing of the shutter rotating plate. Insert the key into the key hole, the shutter turn plate will cover the key hole after closing, and play a role in anti-theft, but users often forget to close the shutter turn plate after pulling out the key after using the car, so that the key hole is exposed to the outside. It directly causes the anti-theft to fail, and there are potential safety hazards, which need to be solved urgently
