[0036] Example 1

[0037] like Figure 1-Figure 12 As shown, a multifunctional electronic mechanical lock is provided in the present embodiment, characterized in that it comprises a lock shell 1, wherein a transmission arm 2 and a driving assembly 5 for driving the transmission arm 2 to rotate are arranged in the lock shell 1, a toggle block 9 is connected to the transmission arm 2, a seat cushion lock slider 10 is slidably arranged in the lock shell 1, the seat cushion lock slider 10 is connected to the inner wall of the lock shell 1 with a seat cushion lock slider spring, the rotation of the transmission arm 2 can drive the toggle block 9 to rotate, and the toggle block 9 can toggle the passive block 11 on the seat cushion lock slider 10 to move forward,

[0038] The lock housing 1 is provided with a lock tongue slider 8, and a lock tongue 7 is connected to the lock tongue slider 8. The left wall of the lock housing 1 is provided with a lock tongue hole, and the lock tongue 7 passes through the lock tongue hole. The bottom of the transmission arm 2 is connected to the crank arm 4. The rotation of the transmission arm 2 drives the crank arm 4 to rotate, and the crank arm 4 can drive the lock tongue slider 8 to move left and right, thereby driving the lock tongue 7 to move left and right.

[0039] A secondary transmission arm 3, an electric switch 12 and a main circuit board 16 are arranged in the lock housing 1. A contact ring 15 is connected to the secondary transmission arm 3. The bottom end of the crank arm 4 enters into the secondary transmission arm 3. A transmission arm spring 22 is connected between the bottom end of the crank arm 4 and the secondary transmission arm 3. The crank arm 4 can drive the secondary transmission arm 3 to rotate, and enter to drive the contact ring 15 to rotate and contact the electric switch spring arm 13 on the electric switch 12. An angle detection magnet 14 is arranged in the secondary transmission arm 3. An angle detection chip for detecting the rotation angle of the angle detection magnet 14 is arranged in the main circuit board 16.

[0040] A mechanical lock core 6 is arranged in the lock housing 1, and a separation spring 17 is provided between the mechanical lock core 6 and the transmission arm 2. Concave and convex parts that cooperate with each other are provided between the mechanical lock core 6 and the transmission arm 2. When the mechanical lock core 6 is pressed down, the concave and convex parts can fit together. Continuing to press the mechanical lock core 6 down can drive the transmission arm 2 and the curved arm 4 to move downward. Rotating the mechanical lock core 6 can drive the transmission arm 2, the curved arm 4 and the auxiliary transmission arm 3 to rotate.

[0041] In this embodiment, through the cooperation of various components, the driving component 5 is controlled by the main circuit board 16. After the driving component 5 is energized, it drives the transmission arm 2 to rotate, and the rotation of the transmission arm 2 drives the crank arm 4 to rotate. The crank arm 4 drives the lock tongue slider 8 to move rightward, and then drives the lock tongue 7 to move rightward into the lock shell 1 to realize the opening of the direction lock. The rotation of the transmission arm 2 drives the crank arm 4 to rotate, and the crank arm 4 drives the auxiliary transmission arm 3 to rotate, and then drives the contact ring 15 to rotate. When the contact ring 15 contacts the switch spring arm 13 on the switch 12, the switch 12 is opened.

[0042] In this embodiment, an angle detection magnet 14 is provided to determine the state of the lock by the angle change of the angle detection magnet 14. For example, when the unlocking action is executed, after the angle detection magnet 14 rotates to the angle set by the main circuit board 16, the drive component 5 will automatically stop.

[0043] In the electric control mode, the mechanical lock core 6 is located above the transmission arm 2. When the electric control mode fails, insert the key into the mechanical lock core 6, press the mechanical lock core 6 down, so that the concave and convex parts fit together, and continue to press the mechanical lock core 6 down, so that the transmission arm 2 and the curved arm 4 continue to move downward. At this time, the mechanical lock core 6 is rotated to drive the transmission arm 2 to rotate. The unlocking process is the same as above, and the direction lock, the electric door switch and the seat cushion lock are opened. In this way, the direction lock, the electric door switch and the seat cushion lock are opened through the two forms of electric control and mechanical keys, and the electric door opening is changed from the rotating contact conduction mode to the light touch conduction mode. There is no wear during use, which solves the problems of poor contact and unclear gear position, and there is no hidden danger of electronic relay conduction failure, so that the lock body mechanism reaches a service life several times that of traditional locks.

[0044] In this embodiment, a lock cover 30 is installed on the top of the lock housing 1. A button circuit board is arranged inside the lock cover 30. The button circuit board is electrically connected to the main circuit board 16. The button circuit board has a wireless sensing module.

[0045] Specifically, the wireless sensing module can be an induction coil for sensing PKE, NFC or Bluetooth, so that the electric control direction lock has an automatic mode. In the automatic mode, according to the software setting of the main circuit board 16, full automatic operation is realized. When the key is in the sensing range, the direction lock, the electric door switch and the seat cushion lock can be automatically opened. When the key leaves the sensing range, according to the software setting of the main circuit board 16, the electric door switch is automatically turned off and the direction is automatically locked. In this embodiment, the drive component 5 is controlled by the main circuit board 16.

[0046] In this embodiment, the main circuit board 16 is provided with a processing circuit and a communication module connected to the outside, which can perform various functions by itself, and can also connect to the external network through the communication module to achieve control and realize the properties of the Internet of Vehicles. The Internet of Things electronic lock can record unlocking records, including time, method and other information, to provide data support for security management. For example, after a vehicle is stolen, the vehicle can be prevented from starting through remote control.

[0047] The present invention protects the mechanical structure design. The main circuit board 16 and the button circuit board are existing structures, and the control circuit can be implemented through simple programming by technicians in this field.
