Detailed Description

As shown in fig. 1 and 2, an automobile ignition lock comprises a base housing 1, a middle ring 2 and a lock cylinder 3, wherein the lock cylinder 3 is arranged in the middle of the base housing 1, and the middle ring 2 is arranged between the base housing 1 and the lock cylinder 3. The bottom of the lock cylinder 3 is provided with an inclined plane which can push the third push block 8 to move towards the outer side of the base shell 1, the third push block 8 is provided with an inclined plane which is matched with the inclined plane at the bottom of the lock cylinder 3, the third push block 8 is movably arranged in the base shell 1, and the outer side of the third push block 8 corresponds to the press signal switch 9. The bottom of a lock hole of the lock cylinder 3 is provided with a first push block 5 capable of moving towards the middle ring, one end of the first push block 5 is provided with an inclined plane matched with the end part of the mechanical key, the other end of the first push block 5 is movably provided with a second push block 6 in the middle ring 2 and the base shell 1, and the outer side of the second push block 6 corresponds to the key signal switch 7.

Furthermore, an electromagnetic lock 4 is arranged on the base shell 1, the electromagnetic lock 4 comprises an electronic control unit and an electromagnetic relay, and an armature of the electromagnetic relay enables the armature to be closed or opened under the control of the electronic control unit; in an initial state, the front end of the armature clamps the convex block on the middle ring 2, and the middle ring 2 cannot rotate together with the base shell 1; under the keyless ignition state, the front end of the armature is sucked and pressed down, so that a convex block on the middle ring 2 is not clamped any more, and the locking state of the middle ring 2 and the base shell 1 is further released, so that the middle ring and the base shell can rotate relatively.

In the invention, in the initial state, the electromagnetic lock and the mechanical key lock are both in a locking state.

When the key is not used for starting, only the lock cylinder 3 needs to be pressed down, the lock cylinder 3 moves inwards, the inclined plane on the lock cylinder 3 extrudes and pushes the third push block 8 to move towards the outer side of the base shell 1, a press-down signal switch 9 for controlling keyless ignition is triggered, K-line encryption communication judgment is carried out through an ignition control unit ECU and a controller, namely, as shown in figure 3, the controller at the outer center searches for a legal key within a certain range, an encrypted data control command is sent through a K line, and after being decrypted to a correct command by the ignition control unit ECU, the encrypted data control command is transmitted to an electronic control unit of the electromagnetic lock 4 to control an electromagnetic relay in the electromagnetic lock 4, so that an armature in the electromagnetic relay is attracted, the front end of the armature is pressed down, a lug on a middle ring is not clamped any more, and the locking state of, so that the electromagnetic lock can rotate relatively and the electromagnetic lock is unlocked. Meanwhile, the middle ring 2 and the lock cylinder 3 are interlocked through the second push block 6, the middle ring 2 and the lock cylinder 3 can only rotate together relative to the base shell 1, and ignition is started.

Inserting a mechanical key for starting, as shown in fig. 4, inserting the mechanical key 10 into a lock hole of the lock cylinder 3, extruding and pushing the end of the mechanical key 10 to push the first push block 5, further pushing the second push block 6 to move towards the outer side of the base shell 1, triggering a key signal switch 7 for controlling the ignition of the inserted key, receiving a signal of inserting the mechanical key by a controller at the outer center, starting a vehicle body control system, simultaneously unlocking the middle ring 2 and the lock cylinder 3, interlocking the middle ring 2 and the base shell 1 through the second push block 6, rotating the lock cylinder 3 relative to the middle ring 2 and the base shell 1, and starting the ignition.

The automobile ignition lock has two functions of keyless electronic control ignition and mechanical key ignition. The starting is very convenient through keyless ignition starting. When the keyless ignition starting fails, the ignition starting can be realized through the mechanical key, so that the ignition stability of the automobile is ensured, and the normal use of a customer is not influenced.
