Detailed Description
In order to make the technical problem, technical solution and advantageous effects solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The electric vehicle anti-theft electromagnetic lock is used for protecting a battery pack of an electric bicycle.
As shown in fig. 1 and 2, in the present embodiment, the anti-theft electromagnetic lock for an electric vehicle includes a battery pack 10, a lock body bracket 20, an iron core 30, a locking bolt 40, a shock-absorbing mute gasket 50, a limit screw 60, a solenoid 70, and a spring 80.
The battery pack 10 is an electric power part of the electric bicycle and provides power for riding the electric bicycle. One side of the bottom of the battery pack 10 is provided with a locking groove 11.
The lock body bracket 20 is disposed adjacent to the lock slot 11. The lock body support 20 is a cuboid frame with an upper opening and a lower opening and a cavity inside, and two sides of the cuboid frame are fixed through fixing screws 21. The lock body bracket 20 is provided with a front through hole 22 at the front end and a rear through hole 23 at the rear end. The front through-hole 22 is a circular hole having outwardly protruding slits 24 formed in upper and lower portions thereof. The rear through hole 23 is a circular hole with two sides having a planar structure.
The iron core 30 is a two-stage cylinder having a through hole at the center, and the diameter of the front stage cylinder is smaller than that of the rear stage cylinder. The front section cylinder is symmetrically provided with convex blocks 31 which protrude outwards. The plunger 30 is disposed within a cavity of the lock body bracket 20. The front section cylinder of the plunger 30 passes through the front through hole 22, and then the plunger 30 is rotated, and when the protruding block 31 is rotated to be engaged with the protruding slot 24, the plunger 30 is assembled with the front section of the lock body bracket 20.
A shock-absorbing silencing washer 50 is provided at the front end of the iron core 30. One end of a limit screw 60 passes through the damping silent gasket 50 and the through hole of the iron core 30 to be connected with the circular groove on the circular cover of the bolt 40; the other end is located outside the lock body bracket 20.
The solenoid 70 is fitted over the outside of the core 20.
The opening and closing of the anti-theft electromagnetic lock of the electric vehicle is controlled by an intelligent key matched with the anti-theft electromagnetic lock of the electric vehicle.
As shown in fig. 3 and 4, when the smart key controls the electromagnetic lock to be powered on, a magnetic field is generated in solenoid 70, and then the magnetic field is strengthened by iron core 30, so that locking bolt 40 is attracted to compress spring 80 and move towards iron core 30, and locking bolt 40 is withdrawn from lock slot 11 at the bottom of battery pack 10, thereby playing a role of unlocking.
As shown in fig. 5 and 6, when the smart key controls the electromagnetic lock to be powered off, the magnetic field generated by solenoid 70 disappears, and then locking bolt 40 moves outward under the rebounding action of spring 80, so that locking bolt 40 moves outward and is inserted into locking groove 11 at the bottom of battery pack 10 to perform a locking function.
