[0039] As Figs. 1-3The present embodiment will describe in detail the structure and working principle of an embedded or external thin mechanical electric drive energy-saving electric mortise lock. The electric mortise lock comprises a lock body shell 1, a mechanical locking mechanism, a lock bolt device 3, a circuit board 17, an electromagnet assembly 4 and related driving and connecting components.

[0040] The lock body shell 1 is the basic structure of the entire lock, designed as a thin structure for embedded installation in the cabinet, thereby minimizing the occupation of the cabinet space. The lock body shell 1 is provided with a mechanical locking mechanism, specifically including a driving rack block 16, a lock bolt swing arm 20, a switch lock swing arm 11, a positioning and locking structure and a driving block spring 15. The lock bolt insertion port 2 is arranged on one side of the lock body shell 1, ensuring accurate docking of the hook lock bolt 3 on the door plate when the door is closed.

[0041] The lock bolt device 3 comprises at least one hook lock bolt 3 installed on the cabinet door plate. When the cabinet door plate is closed, the hook lock bolt 3 is inserted into the lock body shell 1 through the lock bolt insertion port 2 and pushes the driving rack block 16 to slide along the guide rail. The driving rack block 16 is provided with a first rack section 18 on one side, which is engaged with a second rack section 12 on the lock bolt swing arm 20. When the driving rack block 16 translates backward, the first rack section 18 drives the driving rack block 16 to rotate along the circumferential direction of the rotating end, thereby driving the rotation of the lock bolt swing arm 20.

[0042] The other side of the lock bolt swing arm 20 is rotatably installed with the switch lock swing arm 11, and the positioning and locking structure is arranged between the lock bolt swing arm 20 and the switch lock swing arm 11. When the hook lock bolt 3 is completely inserted into the lock bolt insertion port 2, the positioning and locking structure locks the lock bolt swing arm 20, ensuring that the hook lock bolt 3 is securely locked inside the lock body shell 1, thereby improving the security of the lock. The positioning and locking structure comprises a clamping step 13 arranged on the switch lock swing arm 11 and a clamping protrusion 14 arranged on the head of the lock bolt swing arm 20.

[0043] The side of the lock bolt swing arm 20 facing the clamping step 13 is an arc-shaped guide surface 18. When the lock bolt swing arm 20 rotates to the limit position, the clamping protrusion 14 is engaged with the clamping step 13, forming a stable locking state. In addition, the side of the lock bolt swing arm 20 away from the clamping protrusion 14 forms a locking portion 19. After the hook lock bolt 3 is completely inserted into the lock bolt insertion port 2, the locking portion 19 limits the hook lock bolt 3, further ensuring the reliability of the locking.

[0044] The circuit board 17 is installed inside the lock body shell 1, and the detection sensor integrated on the circuit board 17 is an optical sensor for detecting the position and state of the hook lock bolt 3. The circuit board 17 controls the switching action of the electromagnet assembly 4 according to the signal of the detection sensor, realizing the automatic control of the lock.

[0045] The electromagnet assembly 4 is controlled by the circuit board 17, and can drive the mechanical locking mechanism to disengage when receiving the unlocking signal, so as to realize unlocking. Specifically, the electromagnet assembly 4 comprises an electromagnetic valve bracket 4, an electromagnetic valve copper pipe 19, an electromagnetic valve piston 8, a copper coil 5, an electromagnetic valve spring 6, a connecting lug 10, a sliding connection groove 9 and a sliding connection shaft 7.

[0046] The electromagnetic valve copper pipe 19, the electromagnetic valve piston 8 and the copper coil 5 are installed in the electromagnetic valve bracket 4. One end of the electromagnetic valve piston 8 extends into the electromagnetic valve bracket 4, and the other end extends out of the electromagnetic valve bracket 4 and is connected to the connecting lug 10 on the switch lock swing arm 11. The sliding connection shaft 7 is slidingly connected with the connecting lug 10 through the sliding connection groove 9, so as to ensure that the electromagnet assembly 4 can flexibly drive the movement of the switch lock swing arm 11 during the extension and retraction action.

[0047] The electromagnetic valve piston 8 is provided with a limiting screw 28 and is sleeved with the electromagnetic valve spring 6. One end of the electromagnetic valve spring 6 is in contact with the electromagnetic valve bracket 4 for support, and the other end is in contact with the limiting screw 28 for support, so as to ensure that the electromagnetic valve piston 8 can return to the initial position after power-off.

[0048] The rear end of the driving rack block 16 is provided with a driving block spring 15, which provides necessary elastic force during the sliding of the driving rack block 16, so as to ensure that the driving rack block 16 can rebound at the appropriate position and be ready for the next locking operation.

[0049] In actual working process, when the cabinet door is closed, the hook-shaped lock tongue 3 is inserted into the lock body shell 1 through the lock tongue insertion port 2 and pushes the driving rack block 16 to slide along the guide rail. The first rack section 18 on one side of the driving rack block 16 is engaged with the second rack section 12 on the lock tongue swing arm 20, and the sliding of the driving rack block 16 drives the rotation of the lock tongue swing arm 20.

[0050] When the driving rack block 16 slides to the bottom, the clamping protrusion 14 on the lock tongue swing arm 20 is clamped with the clamping step 13 on the switch lock swing arm 11, forming a stable locking structure, so as to ensure that the hook-shaped lock tongue 3 is firmly locked in the lock body shell 1.

[0051] When unlocking is needed, the circuit board 17 receives the unlocking signal, controls the copper coil 5 to be electrified, drives the electromagnetic valve piston 8 to be attracted backward under the action of magnetic force, drives the switch lock swing arm 11 to rotate, and separates from the clamping structure on the lock tongue swing arm 20, so as to release the locking state.

[0052] After the locking is released, the user pulls the cabinet door, and the hook-shaped lock tongue 3 is pulled out of the lock body shell 1. At the same time, the elastic force of the driving block spring 15 makes the driving rack block 16 move backward synchronously, and drives the lock tongue swing arm 20 to return to the position before locking. The lock tongue swing arm 20 returns to the initial state under the action of the driving block spring 15, and is ready for the next locking operation.

[0053] The embedded or externally-hung thin mechanical electric drive energy-saving electric mortise lock of the utility model, through optimizing the lock body structure, realizes the lock body design thinner than the traditional electric mortise lock, can better be embedded in the cabinet body and installed, significantly reduces the cabinet space occupation, and adapts to the high requirement of modern furniture on space utilization rate;

[0054] In addition, the lock body adopts mechanical and electric double drive structure, the lock hook rapidly enters the inside of the lock body and is immediately locked after closing the door, avoids the locking lag phenomenon of the traditional electric mortise lock caused by the response delay of the electromagnet, simultaneously, the operation noise is significantly reduced, and the comfort and the quietness of the environment during use are improved;

[0055] The lock does not need to rely on the continuous power supply of the electromagnet during the door closing and locking process, greatly saves energy, prolongs the battery life, and has significant energy-saving effect;

[0056] The internal mechanical structure is simple and stable, the safety and reliability of the lock are enhanced, the failure risk caused by power fluctuation or mechanical wear is reduced, in addition, the installation mode of the lock is simple and convenient, and the adaptability is strong, can be widely applied to various furniture and cabinet bodies, reduces the installation complexity, and improves the market adaptability.
