Description

Technical Field

[0001] The present invention relates to a lock, and more particularly to an electric lock applied to an electric vehicle or a motorcycle. Background Art

[0002] Generally, the electric lock on an electric vehicle or a motorcycle includes a lock core, a connecting shaft, a rotor and a circuit board. When a matching key is inserted into the lock core and drives the rotor to rotate through the connecting shaft, the moving contact on the rotor contacts the static contact on the circuit board, so that the circuit on the electric vehicle or motorcycle can be connected, thereby realizing normal startup. The keys on existing electric vehicles or motorcycles are all mechanical keys and must be manually inserted and rotated to be opened. However, some users require a more advanced opening method, such as the remote control key applied to a car. As long as the remote control key approaches the car, the car can be unlocked, and at the same time, rotating the opening button can normally open it. At present, there is no such solution for electric vehicles or motorcycles. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the present invention innovatively provides an electric control anti-theft electric lock that can achieve wireless unlocking.

[0004] This electric control anti-theft electric lock includes a lock shell, a rotor, a connecting shaft and a circuit board, and is characterized in that: a face cover with a handle is movably sleeved on the lock shell, an iron core is arranged between the face cover and the connecting shaft, one end of the iron core is axially movable in the face cover, the face cover can drive the iron core to rotate, the other end of the iron core can enter the transmission slot of the connecting shaft and can drive the connecting shaft to rotate, a spring is arranged in the lock shell, one end of the spring acts on the supporting part on the inner wall of the lock shell, the other end of the spring acts on the outer extension part of the iron core, the spring drives the iron core to move towards the face cover, an electromagnetic coil is arranged on the lock shell, the electromagnetic coil is electrically connected to an electronic controller, and a communication chip capable of wireless communication with a remote control key is arranged in the electronic controller. After the electromagnetic coil is energized, it can drive the iron core to move towards the connecting shaft.

[0005] One end of the connecting shaft has a guiding round hole, and the front end of the iron core has a guiding cylinder, and the guiding cylinder of the iron core is located in the guiding round hole of the connecting shaft.

[0006] The transmission slot is a long and flat slot, and the cross section of the iron core is long and flat.

[0007] According to an electric control anti-theft electric lock provided by the present invention, wireless communication is carried out between the electronic controller and the remote control key, and the electronic controller controls the internal transmission connection of the electric control anti-theft electric lock, so that as long as the face cover is manually rotated, startup can be realized, which is very convenient.

[0014] As Figure 1 shown, this electrically controlled anti-theft electric door lock includes a lock housing 5, a rotor 4, a connecting shaft 3 and a circuit board. A face cover 1 with a handle is movably sleeved on the lock housing 5. An iron core 2 is arranged between the face cover 1 and the connecting shaft 3. One end of the iron core 2 is axially movable in the face cover 1. The face cover 1 can drive the iron core 2 to rotate. The other end of the iron core 2 can enter the transmission groove 31 of the connecting shaft 3 and drive the connecting shaft 3 to rotate. A spring 7 is arranged in the lock housing 5. One end of the spring 7 acts on the support part 50 on the inner wall of the lock housing 5, and the other end of the spring 7 acts on the outer extension 21 of the iron core 2. In this way, the spring 7 drives the iron core 2 to move towards the face cover 1. In addition, an electromagnetic coil 6 is arranged on the lock housing 5. The electromagnetic coil 6 is electrically connected to the electronic controller 9. The electronic controller 9 is provided with a communication chip capable of wireless communication with the remote control key 8. After the electromagnetic coil 6 is powered on, it can drive the iron core 2 to move towards the connecting shaft 3.

[0015] The working principle of this electrically controlled anti-theft electric door lock is as follows: As Figure 5 shown, when the remote control key 8 is brought close to one's own vehicle, the electronic controller 9 conducts wireless communication with the remote control key 8, and the electronic controller 9 judges whether the remote control key 8 is matched. If the remote control key 8 is not matched, the electromagnetic coil 6 is not powered on, the face cover 1 rotates, and the iron core 2 can only rotate idly, so that the rotor 4 cannot be driven to rotate and the vehicle cannot be started. When the remote control key 8 is matched, the electronic controller 9 powers on the electromagnetic coil 6. After the electromagnetic coil 6 is powered on, it controls the iron core 2 to move towards the connecting shaft 3. One end of the iron core 2 enters the transmission groove 31 of the connecting shaft 3, so that the iron core 2 and the connecting shaft 3 are in transmission connection. When the face cover 1 is rotated, the connecting shaft 3 can be driven to rotate through the iron core 2, and the connecting shaft 3 drives the rotor 4 to rotate, so that normal starting can be realized. Through this starting method, there is no need for a mechanical key, and unlocking through wireless is more convenient.

[0016] Since the iron core 2 will move axially, in order to play an axial guiding role for the iron core 2 and enable the iron core 2 to more accurately enter the transmission slot 31 of the connecting shaft 3, as Figure 2 shown, one end of the connecting shaft 3 has a guiding round hole 30, and the front end of the iron core 2 has a guiding cylinder 20 (as Figure 3 shown in 4 ), as Figure 1 shown, the guiding cylinder 20 of the iron core 2 is always located in the guiding round hole 30 of the connecting shaft 3. When the iron core 2 moves left and right, since its guiding cylinder 20 is always located in the guiding round hole 30 of the connecting shaft 3, the iron core 2 can very accurately enter the transmission slot 31 of the connecting shaft 3.

[0017] Finally, it is worth mentioning that the transmission slot 31 of the connecting shaft 3 of the present invention is a long and flat slot, and the cross-section of the iron core 2 is long and flat. After the iron core 2 enters the long and flat slot of the connecting shaft 3, it can drive the connecting shaft 3 to rotate as long as it rotates. Of course, in addition to the circular slot, slots of other shapes can also achieve transmission.
