[0022] Example 1

[0023] As the instruction manual Figure 1 and 2 As shown, the utility model provides an electromagnetic double-tongue lock structure, including a shell 1, a reset spring 3 and two electromagnets 2 that attract each other when energized to unlock, the two electromagnets 2 are arranged in the shell 1, the two ends of the reset spring 3 are respectively connected to the two electromagnets 2, the reset spring 3 is fixed to the shell 1, the two ends of the shell 1 are provided with openings, the end of the electromagnet 2 away from the reset spring 3 is provided with a lock tongue 4 that can respond to the movement of the electromagnet 2 in a limited space to unlock, the lock tongue 4 is arranged in a one-to-one correspondence with the opening of the shell 1, and a travel limit mechanism is provided between the lock tongue 4 and the shell 1.

[0024] Specifically, the electromagnet 2 is connected to the power supply through a wire and an unlocking switch. The unlocking switch can be a push switch or a fingerprint switch. If the unlocking switch is a push switch, the unlocking process is that after pressing the unlocking switch, the power supply is turned on to form a power-on circuit. The electromagnet 2 has magnetism under the action of current. According to the setting, the two electromagnets 2 can attract each other under the action of the circuit conduction, and then drive the lock tongue 4 to move toward the shell direction to complete the unlocking. At this time, the reset spring 3 is in a compressed state; when the unlocking switch is released, the circuit is disconnected, the electromagnet 2 loses its magnetism, and the reset spring 3 restores its elasticity. Then, the electromagnet 2 drives the lock tongue 4 to move toward the outside of the shell 1 under the action of the reset spring 3 to complete the locking.

On the other hand, the lock tongue 4 can be limited so that the lock tongue 4 will not fall out when it is pushed out by the reset spring 3.

[0027] As one of the specific implementations, the first limiting member 5 can be a slider arranged on the lock tongue 4, and the second limiting member 6 can be a slide groove arranged on the shell 1. The slider is located in the slide groove and can move along the slide groove. The length of the slide groove is adapted to the stroke of the lock tongue 4 to meet the movement stroke of the lock tongue 4.

[0028] In an optimized implementation mode, the shell 1 is rectangular, and openings are provided at both ends of the shell 1. The electromagnets 2 are arranged side by side in the shell 1, and the lock tongue 4 on the electromagnets 2 is arranged corresponding to the opening of the shell 1, and can be extended out of the shell 1 to complete locking, or retracted into the shell 1 to complete unlocking.
