There are many types of it, including simple circuit products and relatively high-performance products based on chips. The currently widely used electronic password lock is centered around a chip and is realized through programming. In the field of security and technical prevention, the electronic password lock with anti-theft alarm function replaces the traditional mechanical password lock, overcoming the disadvantages of the mechanical password lock such as few password combinations and poor security performance, greatly improving the password lock both technically and in terms of performance.

[0003] Generally, a lock has a lock tongue structure, which is composed of a lock tongue, a lock tongue rod, and a lock tongue spring, and is installed on a lock box. One end of the lock tongue spring is connected to the lock tongue, and the other end abuts against the lock box. By compressing the spring to generate elastic force, the lock tongue can automatically extend and retract in the lock box to achieve the opening and closing of the lock. During the unlocking process, the contraction of the lock tongue needs to overcome the elastic force of the lock tongue spring and the friction between the lock tongue and the lock hole, resulting in a large unlocking resistance.

[0027] Now, in conjunction with the accompanying drawings, a detailed description will be given of the preferred embodiments of the present invention.

[0028] As Figure 1 shown, the lock assembly of the present invention includes an electronic key 100, a lock body 200, and a lock panel 300. The electronic key 100 is detachably connected to the lock panel 300.

[0029] As Figures 2 to 5As shown, the lock body 200 includes a base 1, a power unit 2, a lock tongue 3, a moving plate 4, and a first elastic member 5. The power unit 2 is installed on the base 1, and the power unit 2 is electrically connected to the lock panel 300. The lock tongue 3 can move telescopically, and a limiting member 6 is provided thereon. The moving plate 4 is slidably disposed on the base 1, and the power unit 2 is drivingly connected to the moving plate 4 to drive the moving plate 4 to move. A chute 41 is further provided on the moving plate 2, and the chute 41 includes a first groove section 411 that is inclined with respect to the moving direction of the lock tongue 3. The limiting member 6 is inserted into the chute 41 to realize the linkage between the lock tongue 3 and the moving plate 4. A guiding inclined surface 42 parallel to the first groove section 411 or forming a small angle with the first groove section 411 is provided on one side surface of the moving plate 4. One end of the first elastic member 5 is connected to the lock tongue 3, and the other end abuts against the side surface of the moving plate 4 provided with the guiding inclined surface 42. Among them, when unlocking, the electronic key 100 is installed on the lock panel 300, and the electronic key 100 is electrically connected to the power unit 2, so that the power unit 2 drives the moving plate 4 to move. When the lock tongue 3 is pushed to move telescopically, the limiting member 6 moves in the first groove section 411, and the end of the first elastic member 5 abutting against the side surface of the moving plate 4 moves on the guiding inclined surface 42. When locking, the power unit 2 drives the moving plate 4 to move, the first groove section 411 pushes the limiting member 6 to move, driving the lock tongue 3 to extend, and at the same time the first elastic member 5 moves along the guiding inclined surface 42; when unlocking, the electronic key 100 is installed on the lock panel 300 to electrically connect the electronic key 100 to the power unit 2, and then the power unit 2 drives the moving plate 4 to move, the first groove section 411 pushes the limiting member 6 to move, driving the lock tongue 3 to contract, and at the same time the first elastic member 5 moves along the guiding inclined surface 42. During the entire locking and unlocking process, when the first groove section 411 pushes the lock tongue 3 to move, the first elastic member 5 slides on the guiding inclined surface 42 synchronously. Because the guiding inclined surface 42 is parallel and inclined to the first groove section 411 or forms a small angle with the first groove section 411, the first elastic member 5 does not deform or deforms less. Therefore, when the lock tongue 3 contracts and unlocks, only the friction between the lock tongue 3 and the lock hole needs to be overcome, and there is no need to overcome or less overcome the elastic force of the first elastic member 5, and unlocking can be achieved without a large torque, making unlocking labor-saving.

[0030] As Figure 6 and Figure 7As shown, in this embodiment, a first contact 301 is provided on the lock panel 300, and a second contact 101 corresponding to the first contact 301 is provided on the electronic key 100. When the electronic key 100 is installed on the lock panel 300, the second contact 101 contacts the first contact 301, and the electronic key 100 is electrically connected to the power unit 2. Further, magnets are provided on the electronic key 100 and / or the lock panel 300, and the electronic key 100 is detachably connected to the lock panel 300 by magnetic attraction. In other embodiments, a slot is provided on one of the electronic key 100 and the lock panel 300, and a engaging member is provided on the other, and the electronic key 100 and the lock panel 300 are detachably connected by clamping. Moreover, when the electronic key 100 is installed on the lock panel 300, the electronic key 100 can be used as a handle to open the door panel without separately providing a handle.

[0031] As Figure 2 shown, the lock body 200 further includes a second elastic member 7. The second elastic member 7 is installed on the base 1 and is located on the side where the lock tongue 3 extends. After locking, the second elastic member 7 abuts against the door frame and is compressed and deformed. When locking, the lock tongue 3 is inserted into the lock hole, the door panel is clamped, so that the second elastic member 7 abuts against the door frame and deforms. When unlocking, the lock tongue withdraws from the lock hole, the door panel is released, and the elastic force when the second elastic member 7 returns to its deformed state pushes the door panel out. In this way, after unlocking, the door panel will be pushed open by the second elastic member 7, and it is convenient to open the door panel.

[0032] As Figure 5 shown, the chute 41 further includes a second chute section 412. The second chute section 412 is parallel to the moving direction of the lock tongue 3 and smoothly transitions with one end of the first chute section 411. In this solution, when it is necessary to lock again after unlocking, the lock tongue 3 abuts against the door frame and is stressed, the first elastic member 5 is compressed, the lock tongue 3 moves and contracts and drives the limiting member 4 to slide into the second chute section 412. After the lock tongue 3 is aligned with the lock hole, the lock tongue 3 is inserted into the lock hole under the action of the first elastic member 5, and the first elastic member 5 returns to its initial state to complete the locking. To lock by moving the moving plate 4 requires a mechanical electronic key or a motor to drive the moving plate 4, while in this solution, the setting of the second chute section 412 can enable locking without moving the moving plate 4, which is convenient for locking.

[0033] In this embodiment, the inclination direction of the guiding inclined surface 42 is parallel to the inclination direction of the chute 41. Since the guiding inclined surface 42 and the chute 41 are inclined in parallel and have the same inclination angle, the first elastic member 5 will not deform during the movement of the moving plate 4. Therefore, when the lock tongue 3 contracts and unlocks, only the friction force between the lock tongue 3 and the lock hole needs to be overcome, and the elastic force of the first elastic member 5 does not need to be overcome.

[0034] Further, the sliding groove 41 further includes a third groove section 413, which is perpendicular to the moving direction of the locking tongue 3 and smoothly transitions to the other end of the first groove section 411. When the locking tongue 3 retracts, due to inertia and other factors, the moving plate 4 cannot stop moving in time. When it needs to continue moving, the third groove section 413 can play a buffering role, preventing excessive wear between the sliding groove 41 and the limiting member 4, and thus damaging the moving plate 4.

[0035] As Figure 8 shown, the locking tongue 3 is provided with a receiving cavity 31 and a limiting groove 32 penetrating the side wall of the locking tongue 3. The moving plate 4 passes through the limiting groove 32 and can slide within the limiting groove 32. The first elastic member 5 is disposed within the receiving cavity 31 and abuts between the receiving cavity 31 and the side surface of the moving plate 4 provided with the guiding inclined surface 42. The receiving cavity 31 can limit the position of the first elastic member 5, preventing the first elastic member 5 from moving left and right and affecting the locking or unlocking effect. Preferably, the first elastic member 5 is a spring.

[0036] As Figure 9 shown and Figure 10 , the locking tongue mechanism 100 further includes a tongue seat 8. The tongue seat 8 is provided with a tongue cavity 82 having at least one open end 81 and a plate groove 83 penetrating the side wall of the tongue cavity 82. The locking tongue 3 is disposed within the tongue cavity 82 and can extend out of or retract into the tongue cavity 82 from the open end 81; the moving plate 4 passes through the plate groove 83 and can slide within the plate groove 83.

[0037] As Figure 8 shown, one of the tongue cavity 53 and the locking tongue 3 is provided with a guiding protrusion extending along the moving direction of the locking tongue 3, and the other is provided with a guiding groove 13 that is slidably adapted to the guiding protrusion. Specifically, the locking tongue 3 is provided with a guiding groove 33, and a guiding protrusion is provided within the tongue cavity 53. Through the cooperation of the guiding protrusion and the guiding groove 33, the moving direction of the locking tongue 3 can be restricted, preventing the locking tongue 3 from shifting.

[0038] As Figure 3 and Figure 5 shown, the end of the moving plate 4 located outside the tongue seat 8 is provided with an engaging portion 43. The lock body 200 further includes a gear 9, and the power unit 2 is a motor. The gear 9 is connected to the rotating shaft of the motor and meshes with the engaging portion 43. Specifically, when unlocking, the motor is turned on, causing the motor to drive the gear 8 to rotate, thereby driving the moving plate 4 to move. When the moving plate 4 moves, the limiting member 4 moves along the first groove section 411, driving the locking tongue 3 to retract.

[0039] As Figure 5 shown, the end of the moving plate 4 located outside the tongue seat 8 is provided with a guiding groove 44 for guiding the movement of the moving plate 4. The base 1 is provided with a guiding member, and the guiding member passes through the guiding groove 44 to prevent the moving plate 4 from shifting during movement.

[0040] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
