[0001] The present invention relates to the technical field of locks, and in particular to a lock body and an intelligent lock. Background Art

[0002] With the continuous advancement of science and technology, various forms of locks have appeared in our lives, including password locks and fingerprint locks. Among them, the password lock is an electronic product that controls the circuit or chip operation (access control system) through password input, thereby controlling the closing of the mechanical switch to complete the task of unlocking and locking. There are many types of it, including simple circuit products and cost-effective products based on chips. The most widely used electronic password locks are based on chips and are implemented through programming. In the field of security technology prevention, electronic locks with anti-theft alarm functions replace traditional mechanical password locks, overcoming the shortcomings of mechanical password locks with small passwords and poor security performance, making password locks greatly improved in both technology and performance.

[0003] Common locks all have 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 is against the lock box. The spring compression generates elastic force, allowing the lock tongue to automatically expand and contract in the lock box to achieve the purpose of opening and closing the lock. During the unlocking process, the lock tongue needs to overcome the elastic force of the lock tongue spring and the friction between the lock tongue and the keyhole to shrink, resulting in a large unlocking resistance. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a lock body and an intelligent lock to overcome the defect of the existing lock tongue structure having large resistance when unlocking the lock in view of the above-mentioned defects of the prior art.

[0005] The technical solution adopted by the present invention to solve its technical problems is as follows: a lock body is provided, comprising a base and a lock tongue, the lock tongue is telescopically movable and is provided with a limit piece; a movable plate, the movable plate is slidably arranged on the base, the movable plate is provided with a slide groove, the slide groove comprises a first slot section inclined relative to the moving direction of the lock tongue; the limit piece is penetrated in the slide groove to realize the linkage between the lock tongue and the movable plate; a guide slope parallel to the first slot section or forming a small angle with the first slot section is provided on one side surface of the movable plate; a first elastic member, one end of the first elastic member is connected to the lock tongue, and the other end abuts against the side surface of the movable plate provided with the guide slope; a power unit, the power unit is arranged on the base, and is transmission-connected with the movable plate, and is used to drive the movable plate to move; wherein, when the power unit drives the movable plate to move, and pushes the lock tongue to telescopically move, the limit piece moves in the first slot section, and one end of the first elastic member abutting against the side surface of the movable plate moves on the guide slope.

[0006] A further preferred solution of the present invention is that the lock body further includes a second elastic member, which is installed on the base and located on the side where the lock tongue extends; wherein, after locking, the second elastic member abuts against the door frame and is compressed and deformed.

[0007] A further preferred solution of the present invention is that the chute further includes a second groove section, which is parallel to the moving direction of the lock tongue and smoothly transitions with one end of the first groove section.

[0008] A further preferred solution of the present invention is that the chute further includes a third groove section, which is perpendicular to the moving direction of the lock tongue and smoothly transitions with the other end of the first groove section.

[0009] A further preferred solution of the present invention is that the lock tongue is provided with a receiving cavity and a limiting groove penetrating the side wall of the lock tongue and the receiving cavity. The moving plate passes through the limiting groove and can slide in the limiting groove. The first elastic member is arranged in the receiving cavity and abuts between the receiving cavity and the side surface of the moving plate provided with a guiding inclined surface.

[0010] A further preferred solution of the present invention is that the lock body further includes a tongue seat, which is provided with a tongue cavity with at least one open end and a plate groove penetrating the side wall of the tongue cavity; the lock tongue is arranged in the tongue cavity and can extend out of or retract into the tongue cavity from the opening; the moving plate passes through the plate groove and can slide in the plate groove.

[0011] A further preferred solution of the present invention is that one of the tongue cavity and the lock tongue is provided with a guiding protrusion extending along the moving direction of the lock tongue, and the other is provided with a guiding groove slidably adapted to the guiding protrusion.

[0012] A further preferred solution of the present invention is that the end of the moving plate located outside the tongue seat is provided with an engaging portion, and the lock body further includes a gear, and the power unit is a motor; the gear is connected to the rotating shaft of the motor and meshes with the engaging portion.

[0013] A further preferred solution of the present invention is that the end of the moving plate located outside the tongue seat is provided with a guiding groove for guiding the movement of the moving plate, and the base is provided with a guiding member; the guiding member penetrates through the guiding groove.

[0014] The present invention also provides an intelligent lock: including the lock body as described above.

[0015] The beneficial effects of the present invention are as follows: when locking, the power unit drives the moving plate to move, the first groove section pushes the limiting member to move, driving the lock tongue to extend, and at the same time, the first elastic member moves along the guiding inclined surface; when unlocking, the power unit drives the moving plate to move, the first groove section pushes the limiting member to move, driving the lock tongue to contract, and at the same time, the first elastic member moves along the guiding inclined surface. During the entire locking and unlocking process, when the first groove section pushes the lock tongue to move, the first elastic member moves synchronously on the guiding inclined surface. Since the guiding inclined surface is parallel and inclined to the first groove section or forms a small angle with the first groove section, the first elastic member will not deform or deform less. Therefore, when the lock tongue contracts and unlocks, only the friction between the lock tongue 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, and no large torque is required to unlock, making the unlocking labor-saving.

[0024] Now, in conjunction with the drawings, a detailed description of the preferred embodiments of the present invention will be given.

[0025] Such as Figures 1 to 4As shown, for ease of description, the lock body 100 of the present invention 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 is in driving connection with the moving plate 4 for driving the moving plate 4 to move. The lock tongue 3 is telescopically movable and is provided with a limiting member 6 thereon. The moving plate 4 is slidably disposed on the base 1, and the power unit 2 is in driving connection with the moving plate 4 and can drive the moving plate 4 to move. The moving plate 2 is further provided with a chute 41, and the chute 41 includes a first groove section 411 that is inclined relative 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 the power unit 2 drives the moving plate 4 to move and pushes the lock tongue 3 to telescopically move, 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, drives 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 power unit 2 drives the moving plate 4 to move, the first groove section 411 pushes the limiting member 6 to move, drives 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 will not deform or deform 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 it is not necessary to overcome or less overcome the elastic force of the first elastic member 5, and no large torque is required to unlock, and the unlocking is labor-saving.

[0026] As Figure 1 shown, the lock body 100 further includes a second elastic member 7, and the second elastic member 7 is installed on the base 1 and is located on the side where the lock tongue 3 extends; among them, 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, and 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 deformation 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.

[0027] As Figure 4As shown, the sliding groove 41 further includes a second groove section 412 which is parallel to the moving direction of the locking tongue 3 and smoothly transitions with one end of the first groove section 411. In this solution, when it is necessary to lock again after unlocking, the locking tongue 3 abuts against the door frame and is stressed, the first elastic member 5 is compressed, the locking tongue 3 moves and contracts, and drives the limiting member 4 to slide into the second groove section 412. After the locking tongue 3 is aligned with the keyhole, the locking tongue 3 is inserted into the keyhole under the action of the first elastic member 5, and the first elastic member 5 returns to its initial state to complete the locking. Locking by moving the moving plate 4 requires a mechanical key or a motor to drive the moving plate 4, while in this solution, the setting of the second groove section 412 enables locking without moving the moving plate 4, which is convenient for locking.

[0028] In this embodiment, the inclination direction of the guiding inclined surface 42 is parallel to the inclination direction of the sliding groove 41. Since the guiding inclined surface 42 and the sliding groove 41 are inclined in parallel and have the same inclination angle, during the movement of the moving plate 4, the first elastic member 5 will not deform. Therefore, when the locking tongue 3 retracts to unlock, only the friction between the locking tongue 3 and the keyhole needs to be overcome, and the elastic force of the first elastic member 5 does not need to be overcome.

[0029] Furthermore, 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 with the other end of the first groove section 411. When the locking tongue 3 retracts, the moving plate 4 cannot stop moving in time due to inertia and the like. When it needs to continue moving, the third groove section 413 can play a buffering role to avoid excessive wear between the sliding groove 41 and the limiting member 4, and further damage the moving plate 4.

[0030] As Figure 5 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 in the limiting groove 32. The first elastic member 5 is arranged in 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 to prevent the first elastic member 5 from moving left and right, affecting the locking or unlocking effect. Preferably, the first elastic member 5 is a spring.

[0031] As Figure 6 shown and Figure 7 , the locking tongue mechanism 100 further includes a tongue seat 8. The tongue seat 8 is provided with a tongue cavity 82 with at least one end open 81 and a plate groove 83 penetrating the side wall of the tongue cavity 82. The locking tongue 3 is arranged in the tongue cavity 82 and can extend out of or retract into the tongue cavity 82 from the opening 81; the moving plate 4 passes through the plate groove 83 and can slide in the plate groove 83.

[0032] As Figure 5As shown, a guiding projection extending along the moving direction of the locking tongue 3 is provided on one of the tongue cavity 53 and the locking tongue 3, and a guiding groove 13 slidably adapted to the guiding projection is provided on the other. Specifically, a guiding groove 33 is provided on the locking tongue 3, and a guiding projection is provided in the tongue cavity 53. Through the cooperation of the guiding projection and the guiding groove 33, the moving direction of the locking tongue 3 can be restricted to prevent the locking tongue 3 from shifting.

[0033] As Figure 2 and Figure 4 shown, an engaging portion 43 is provided at one end of the moving plate 4 located outside the tongue seat 8. The lock body 100 further includes a gear 9. 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 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.

[0034] As Figure 4 shown, a guiding groove 44 for guiding the movement of the moving plate 4 is provided at one end of the moving plate 4 located outside the tongue seat 8. The base 1 is provided with a guiding member which passes through the guiding groove 44 to prevent the moving plate 4 from shifting during movement.

[0035] The present invention also provides an intelligent lock including the lock body 100 as described above. Specifically, the intelligent lock may include a password input module, a fingerprint input module or a face recognition module, which can be set according to requirements.

[0036] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. For those skilled in the art, the technical solutions recorded in the above embodiments can be modified, or some of the technical features can be equivalently replaced; and all such modifications and replacements should fall within the protection scope of the appended claims of the present invention.
