After unlocking, the safe door will automatically open, and when the safe door is closed, it will be automatically locked. The box body assembly 1 is provided with a safe inner box 12, and the safe inner box 12 is made of velvet, which is convenient for storing jewelry and jewels. The outer shell of the box body assembly 1 is made of high-strength steel plate, which can resist external impacts and damages.

[0033] The lock mechanism assembly 3 is installed and fixed on the box body assembly 1. One end of the gas spring support rod 4 is connected to the box body assembly 1 and the other end is connected to the door panel assembly 2. When unlocking, the gas spring support rod 4 is released due to being compressed and pushes open the door, and when closing the door, the gas spring support rod 4 is compressed.

[0034] The door panel assembly 2 includes a door panel 21, and a lock catch 22 is welded on the door panel 21. The lock catch 22 is provided with a rectangular opening matching the lock tongue hook 321.

[0035] The lock mechanism assembly 3 mainly consists of a lock mechanism frame 31, a lock tongue 32, a clutch block 33, a motor cam 34, a slide plate 35, a mechanical lock dial 36, a tension spring 37 and a plastic bracket 38 for the motor battery box, etc.; the plastic bracket 38 for the motor battery box is formed with a first slide plate positioning boss 381 and a second slide plate positioning boss 382.

[0036] The lock mechanism frame 31 is fixed with a lock tongue positioning pin 312, a clutch block positioning pin 313 and a rubber ring 314. The lock tongue 32 is positioned on the lock tongue positioning pin 312 and can rotate. The clutch block 33 is positioned on the clutch block positioning pin 313 and can rotate. The lock tongue 32 is restricted by the rubber ring 314 when rotating counterclockwise to the open door position.

[0037] The locking tongue closing section 322 is an arc and an external angle centered on the clutch block positioning pin 313. The clutch block closing section 332 is an arc and an internal angle that matches the locking tongue closing section 322. The locking tongue separating section 323 is an arc centered on the locking tongue positioning pin 312. The clutch block separating section 333 is an arc that matches the locking tongue separating section 323. One end of the tension spring 37 is sleeved on the locking tongue tension spring hook 325, and the other end is sleeved on the clutch block tension spring hook 335. The locking tongue 32 and the separating block 33 are subjected to the pulling force of the tension spring 37 to keep their closing sections or separating sections in contact, as Figure 3a 、 Figure 4a and Figure 5a shown.

[0038] The motor battery box plastic bracket 38 can fix the motor 8, the circuit board 9, and position the sliding plate 35 for horizontal movement and place the battery box 10. The battery box 10 is provided with a battery box cover plate 11. The motor battery box plastic bracket 38 is installed and fixed on the lock mechanism frame 31. The motor 8 and the circuit board 9 are clamped on the motor battery box plastic bracket 38 and fixed. The battery box 10 is placed in the battery box cavity (not marked) of the motor battery box plastic bracket 38, as Figure 3a 、 Figure 3b 、 Figure 4a 、 Figure 4b 、 Figure 5a and Figure 5b shown.

[0039] Please refer to Figure 3a and Figure 4a . When the motor 8 is not powered on, it can rotate freely. When powered on, it rotates counterclockwise (in the direction of the front view). The length of the power-on time is set by the circuit board chip according to the time required to open the door. A motor cam 34 is connected to the drive shaft of the motor 8. When the motor cam 34 rotates counterclockwise with the motor 8, the eccentric pin 341 acts on the motor drive section 331 to rotate the clutch block 33 counterclockwise. The internal angle of the motor drive section 331 is the position that restricts the continuous rotation of the motor 8, that is, the position where the clutch block closing section 332 is separated from the locking tongue closing section 322. When the eccentric pin 341 rotates to the internal angle of the motor drive section 331, the motor 8 cannot rotate although it is in the powered-on state.

[0040] The mechanical lock 7 is installed and fixed on the box body assembly 1. The lock core end is connected with a mechanical lock dial 36. When the mechanical lock 7 is opened / closed, the mechanical lock dial 36 rotates with it, as Figure 1b 、 Figure 2b 、 Figure 3a 、 Figure 3b 、 Figure 4a 、 Figure 4b 、 Figure 5a and Figure 5b shown.

[0041] Please refer to Figure 3a 、 Figure 3b 、 Figure 4a 、 Figure 4b 、 Figure 5a 、 Figure 5b , the skateboard 35 is provided with a driving cavity 351, a bent end 352, a first positioning groove 353 and a second positioning groove 354. The mechanical lock dial 36 is arranged in the driving cavity 351. The first positioning groove 353 matches with the first skateboard positioning boss 381, and the second positioning groove 354 matches with the second skateboard positioning boss 382. The skateboard 35 is positioned by the first skateboard positioning boss 381 and the second skateboard positioning boss 382 in the lock mechanism frame 31 and the motor battery box plastic bracket 38 and can move horizontally. The mechanical lock dial 36 is in the driving cavity 351. Turning the mechanical lock 7 on / off can make the skateboard 35 move horizontally to the on / off lock position.

[0042] Closed door state: The lock tongue hook 321 is in the lock hole 221. Under the pulling force of the tension spring 37, the lock tongue closing section 322 is in contact with the clutch block closing section 332, restricting the counterclockwise rotation (i.e., the opening direction rotation) of the lock tongue 32, and the safe door is locked, as shown in Figure 1a 、 Figure 1b 、 Figure 3a and Figure 3b shown.

[0043] Fingerprint / password opening (mechanical lock locking): When the circuit board 9 receives the correct signal from the fingerprint sensor 5 or the password key 6, the motor 8 is powered on, and the motor cam 34 rotates counterclockwise. The eccentric pin 341 acts on the motor driving section 331 to overcome the pulling force of the tension spring 37 and drive the clutch block 33 to rotate counterclockwise. When the eccentric pin 341 reaches the inner corner of the motor driving section 331, the motor 8 stops rotating. At this time, the clutch block closing section 332 is separated from the lock tongue closing section 322. Under the thrust of the gas spring support rod 4, the lock hole 221 acts on the lock tongue hook 321 with an upward (opening direction) force to make the lock tongue 32 rotate counterclockwise, and the lock catch 22 is separated from the lock tongue hook 321. In addition, under the pulling force of the tension spring 37, the lock tongue separating section 323 is in contact with the clutch block separating section 333, and at the same time, the lock tongue 32 is limited by the rubber ring 314 and stops rotating. At this time, it is in the open door position, and the safe door automatically opens, as shown in Figure 2a 、 Figure 2b 、 Figure 2c 、 Figure 4a and Figure 4b shown.

[0044] Opening the mechanical lock: The mechanical lock dial 36 rotates clockwise, driving the driving cavity 351 to drive the sliding plate 35 to move leftward. The bent end 352 acts on the mechanical lock driving end 334 to drive the clutch block 33 to rotate counterclockwise to the unlocking position. At this time, the closed section 332 of the clutch block is separated from the closed section 322 of the lock tongue. Under the thrust of the gas spring support rod 4, the locking hole 221 acts on the lock tongue hook 321 with an upward (door-opening direction) force to make the lock tongue 32 rotate counterclockwise. The lock catch 22 disengages from the lock tongue 32. Additionally, under the pulling force of the tension spring 37, the separated section 323 of the lock tongue fits with the separated section 333 of the clutch block. At the same time, the lock tongue 32 is limited by the rubber ring 314 and stops rotating. At this time, it is in the door-opening position, and the safe door automatically opens, as Figure 2a , Figure 2b , Figure 2c , Figure 5a and Figure 5b shown.

[0045] Closing the door (locking the mechanical lock): When closing the door, the lock catch 22 acts on the door-closing section 324 of the lock tongue to make the lock tongue 32 rotate clockwise. At the same time, the lock tongue hook 321 enters the locking hole 221. The separated section 323 of the lock tongue is separated from the separated section 333 of the clutch block. Additionally, under the pulling force of the tension spring 37, the clutch block 33 rotates clockwise, and the closed section 332 of the clutch block fits with the closed section 322 of the lock tongue. At the same time, the motor driving section 331 acts on the eccentric pin 341 to make the motor cam 34 rotate back to the door-closing position, and the safe door is automatically locked.

[0046] Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications and improvements without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be defined by the claims.
