[0026] As Figure 1 and 3 shown, the automatic door lock includes a housing 40. A flip lock tongue 10 is provided in the housing 40. The flip lock tongue 10 cooperates with a lock tongue slider 12 to achieve flipping. The lock tongue 10 has an arc surface that cooperates with the arc surface of the lock tongue slider 12 to achieve the flipping of the flip lock tongue 10. When the flip lock tongue 10 is inserted into the door frame, the door can be closed and fixed. When an external force pushes the door, the flip lock tongue 10 will flip away from the door frame to open the door; similarly, when closing the door, the flip lock tongue 10 can also flip and then insert into the door frame to close the door. Therefore, by providing a locking slider 20 to lock and unlock the flip lock tongue 10, the locking function of the door lock can be achieved. Figure 1As shown, a slot 11 is formed in the flipping lock tongue 10; the locking slider 20 is movably arranged in the housing 40, and the locking slider 20 can slide up and down. Moreover, the locking slider 20 is provided with a bolt 21 that cooperates with the slot 11. When the locking slider 20 slides upward, the bolt 21 is inserted into the slot 11 to lock the flipping lock tongue 10 by the locking slider 20; when the locking slider 20 slides downward, the bolt 21 is withdrawn from the slot 11, thereby unlocking the flipping lock tongue 10 by the locking slider 20. Similarly, the locking slider 20 can also be arranged above the flipping lock tongue 10, and the locking slider 20 can also slide up and down. When the locking slider 20 slides downward, the bolt 21 is inserted into the slot 11 to lock the flipping lock tongue 10 by the locking slider 20; when the locking slider 20 slides upward, the bolt 21 is withdrawn from the slot 11, thereby unlocking the flipping lock tongue 10 by the locking slider 20. As Figure 3 shown, a first linkage assembly and a second linkage assembly are further provided to independently control the locking slider 20, that is, to control its up and down sliding, so as to control the insertion or withdrawal of the bolt 21 from the slot 11.
[0027] In another embodiment of the present application, as Figure 2 and Figure 3As shown, the first linkage assembly includes a motor 43, which is fixedly connected to the housing 40, and the motor 43 provides the first linkage assembly with rotational power. A gear transmission assembly is also provided to connect and cooperate with the motor 43. The first dial plate 41 has gear teeth, and the motor 43 drives the gear transmission assembly to drive the first dial plate 41 to rotate. The first dial plate 41 is provided with a pair of first bosses 44; the switch swing arm 30 has a long arm 31, a short arm 32 and a swing arm torsion spring connecting end 33, the locking slider 20 is provided with a slider plug hole 22, the short arm 32 is plugged into the slider plug hole 22, and the long arm is limited between the pair of first bosses 44, that is, the first dial plate 41 can rotate to toggle the switch swing arm 30, and the switch swing arm 30 controls the locking slider 20 to slide up and down through the slider plug hole 22, and the swing arm torsion spring connecting end 33 is connected to the swing arm torsion spring, and the swing arm torsion spring can return the switch swing arm 30. The gear transmission assembly includes a combination gear 42 and a bevel gear, the combination gear has spur gears and bevel gears, the output end of the motor 43 is sleeved with the bevel gear, the bevel gear meshes with the bevel gear, and the spur gear meshes with the gear teeth of the first dial plate 41, thereby realizing that the motor controls the first linkage assembly to drive the locking slider 20 to slide up and down. In this structure, the motor 43 can lock 20 and unlock the flip lock tongue 10 through the locking slider, the motor rotates to drive the motor bevel gear to rotate, the bevel gear drives the combination gear 42 meshed with it, the combination gear 42 drives the first dial plate 41 meshed with it to rotate, the motor 43 toggles the first dial plate 41 assembly to control the switch swing arm 30 to swing, and the switch swing arm 30 controls the locking slider 20 to move up and down, thereby realizing the locking and unlocking of the flip lock tongue 10. The flip lock tongue 10 adopts a spring oblique tongue structure. When the door is closed, whether it is locked or not, the lock tongue extends into the buckle plate, so that the door leaf and the door frame are connected as one, and it really plays the role of a door bolt. The outer side of the lock body adopts motor induction opening method, and the motor-related components adopt a variable speed gear set structure and a lever structure. It has a simple structure, small starting force, low power consumption, low failure rate and long service life.
[0028] In another embodiment of the present application, Figure 3 As shown, the second linkage assembly includes a mechanical gear 54, a switch swing arm 30 and a second shift plate 52 with gear teeth, the second shift plate 52 is provided with a pair of second bosses 54, the switch swing arm 30 has a long arm 31, a short arm 32 and a swing arm torsion spring connecting end 33, the locking slider 20 is provided with a slider insertion hole 22, the long arm 31 is limited between the pair of second bosses 54, the short arm 32 is inserted into the slider insertion hole 22, and the swing arm torsion spring connecting end 33 is connected to the swing arm torsion spring. Figure 4The inner door handle 60 shown, the square core connected to the inner door handle 60, the square core kit 50 connected to the square core, the square core kit 50 has gear teeth, and the gear teeth of the square core kit 60 mesh with the mechanical gear 54. The square core kit 50 is provided with a square hole, the square core is inserted into the square hole, and the square core kit 50 is connected with a torsion spring, which is reset by the torsion spring after the door handle is turned. The inner door handle can lock and unlock the flip lock tongue 10 through the locking slider 20. When the inner door handle 60 rotates, it drives the square core kit 50 to rotate. The square core kit 50 drives the mechanical gear 54 meshing with it to rotate. The mechanical gear 54 drives the second dial 52 meshing with it to rotate. The second dial 52 controls the swing of the switch swing arm 30. The switch swing arm 30 controls the up and down movement of the locking slider 20, thus realizing the locking and unlocking of the flip lock tongue. When the flip lock tongue is locked and an external force is used to open the door, the flip lock tongue cannot be flipped. The flip lock tongue is locked by the locking slider, and the lock body thus achieves the locking function; when the flip lock tongue is unlocked and an external force is used to open the door, the flip lock tongue is forced to flip to achieve the unlocking function. The switch swing arm will be positioned at the last operated position under the action of the swing arm torsion spring; when the inner door handle 60 is released, the second dial 52 will return to the initial angle under the action of the square core torsion spring. When the second dial 52 returns to the initial angle, when the motor 43 locks or unlocks, it is not interfered by the second dial; after the motor 43 locks or unlocks, the electronic control program will control the motor to reverse to make the first dial 41 return to the initial angle. When the first dial 41 returns to the initial angle, when the inner door handle locks or unlocks, it is not interfered by the first dial 41 assembly. When the electronic control component fails and the motor 43 cannot operate normally, the inner door handle 60 can still lock and unlock the flip lock tongue 10 through the locking slider 20 to achieve locking and unlocking. The inner side of the lock body is opened by rotating the inner door handle, and the structure is stable and reliable. That is, the indoor side is a pure mechanical opening method, without circuit operation, which is both power-saving and safe. And regardless of whether the outside of the lock body is locked or not, the indoor side can rotate the inner door handle to pull the door open to meet the rapid escape function. Pulling up the inner door handle 60 can lock it, and pressing down the inner door handle 60 can unlock it. The operation is simple and clear, in line with people's usage habits, and only the inner door handle is exposed on the indoor side without other knobs and other accessories, and the overall appearance is simple and clean.
