Description

Technical Field

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

[0002] An intelligent lock refers to a composite lock that is different from a traditional mechanical lock and has security, convenience, and advanced technology. Few existing intelligent locks can be fully automatically unlocked. Usually, after verification, the main lock tongue is retracted into the lock body by turning the door handle. In addition, the internal structure of existing intelligent locks is complex, and there are problems of poor use stability and security. Summary of the Invention

[0003] In view of the above problems, the present invention overcomes at least one deficiency and provides a fully automatic lock.

[0004] The technical solution adopted by the present invention is as follows:

[0005] A fully automatic lock includes a lock shell assembly, on which are installed:

[0006] A locking and unlocking mechanism for the lock tongue;

[0007] A main lock tongue, which is slidably arranged on the lock shell assembly. The main lock tongue includes a lock tongue portion and a positioning portion;

[0008] A transmission mechanism, which is used to cooperate with the locking and unlocking mechanism of the lock tongue to unlock the locking and unlocking mechanism of the lock tongue, and is also used to cooperate with the main lock tongue to make the lock tongue portion penetrate out of the lock shell assembly or retract into the lock shell assembly; the transmission mechanism includes a driving member and a main lock tongue dial block. The driving member is rotatably installed on the lock shell assembly, and the main lock tongue dial block is rotatably installed on the lock shell assembly and cooperates with the driving member. The driving member can drive the main lock tongue dial block to rotate. The main lock tongue dial block has a first transmission portion that cooperates with the positioning portion of the main lock tongue. When the main lock tongue dial block rotates, the main lock tongue can be driven to slide through the first transmission portion, so that the lock tongue portion penetrates out of the lock shell assembly or retracts into the lock shell assembly; the driving member also has a first convex portion. When the driving member drives the main lock tongue dial block to rotate to retract the main lock tongue into the lock shell assembly, the first convex portion is used to cooperate with the locking and unlocking mechanism of the lock tongue to unlock the locking and unlocking mechanism of the lock tongue;

[0009] An electric drive mechanism for driving the driving member to rotate.

[0010] The electric drive mechanism can drive the driving member to rotate, so that the first transmission portion can rotate synchronously. Under the action of the first transmission portion, the main lock tongue can be driven to penetrate out of the lock shell assembly or retract into the lock shell assembly.

[0011] In the closed state of the door, in addition to opening the main lock tongue, it is also necessary to unlock the locking and unlocking mechanism of the lock tongue. When the driving member drives the main lock tongue block to rotate and retract the main lock tongue into the lock housing assembly in this application, the first convex portion of the driving member can cooperate with the locking and unlocking mechanism of the lock tongue to unlock the locking and unlocking mechanism of the lock tongue, so that the door opening operation can be realized. The transmission mechanism of this application has a simple and reliable structure.

[0012] In one embodiment of the present invention, the positioning portion has a first notch, the first notch has a first side wall and a second side wall, the first side wall is close to the lock tongue portion, and the second side wall is far from the lock tongue portion. The first transmission portion cooperates with the first notch to drive the main lock tongue to slide through the first notch. When the lock tongue portion of the main lock tongue penetrates out of the lock housing assembly, the first transmission portion abuts against the first side wall. When the lock tongue portion of the main lock tongue retracts into the lock housing assembly, the first transmission portion abuts against the second side wall; the second side wall has a buffer area. After the lock tongue portion of the main lock tongue retracts into the lock housing assembly, the first transmission portion can continue to rotate in the buffer area; when the driving member drives the first transmission portion to rotate and retracts the lock tongue portion into the lock housing assembly, and then the driving member continues to rotate, while the first transmission portion idles in the buffer area, the first convex portion cooperates with the locking and unlocking mechanism of the lock tongue to unlock the locking and unlocking mechanism of the lock tongue.

[0013] The buffer area provided on the second side wall is to provide time for the first convex portion to cooperate with the locking and unlocking mechanism of the lock tongue, so that the locking and unlocking mechanism of the lock tongue will not be unlocked when unlocking the main lock tongue, effectively ensuring that the main lock tongue can reliably slide into the lock housing assembly.

[0014] In actual use, the buffer area can be an arc surface.

[0015] In one embodiment of the present invention, the main lock tongue block and the driving member have the same rotation axis, and there is an idle rotation structure between the main lock tongue block and the driving member;

[0016] The idle rotation structure includes a first mating block provided on the main lock tongue block and a second mating block provided on the driving member. The main lock tongue block can idle relative to the driving member by a set angle. When the driving member rotates and the second mating block abuts against the first mating block, the driving member can continue to rotate in the same direction to drive the main lock tongue block to rotate synchronously;

[0017] After the lock tongue portion of the main lock tongue penetrates out of the lock housing assembly, the driving member can be reset. When the main lock tongue block is driven by other mechanisms, the main lock tongue block can idle relative to the driving member and unlock the main lock tongue;

[0018] The full-automatic lock further includes a mechanical unlocking mechanism, and the mechanical unlocking mechanism is used to drive the main lock tongue block to idle and retract the lock tongue portion into the lock housing assembly in the state where the lock tongue portion penetrates out of the lock housing assembly.

[0019] The idle running structure can prevent the main lock tongue push block from generating an acting force with the driving member when the mechanical unlocking mechanism is working, thereby ensuring the reliable and smooth operation of the mechanical unlocking mechanism.

[0020] In one embodiment of the present invention, the mechanical unlocking mechanism comprises:

[0021] A mechanical shift block is rotatably mounted on the lock housing assembly, the mechanical shift block has a slot, and the mechanical shift block has a first driving part and a second driving part;

[0022] The second paddle is rotatably mounted on the lock housing assembly, one end of the second paddle cooperates with the first driving part, and the other end cooperates with the main lock tongue paddle block. The mechanical paddle block rotates, and the first driving part can drive the second paddle to rotate. The rotation of the second paddle drives the main lock tongue paddle to rotate idly, thereby unlocking the main lock tongue. The second driving part is used to cooperate with the locking and unlocking mechanism of the lock tongue to unlock the locking and unlocking mechanism of the lock tongue after the second paddle drives the main lock tongue paddle to unlock the main lock tongue.

[0023] “When the main lock tongue push block unlocks the main lock tongue” means that the main lock tongue push block drives the main lock tongue to slide into the lock housing assembly.

[0024] The slot can cooperate with a rod, such as a square rod, through which the mechanical shift block can be driven to rotate. In actual use, the handle inside the door can drive the mechanical shift block to rotate through the square rod. In actual use, the mechanical unlocking mechanism also includes a first resetting elastic member.

[0025] In one embodiment of the present invention, the locking and unlocking mechanism of the lock tongue includes:

[0026] A lock tongue assembly is slidably arranged on the lock housing assembly, and the lock tongue assembly comprises a connecting block and a lock tongue rotatably mounted on the connecting block;

[0027] A lock tongue assembly reset member is mounted on the lock housing assembly and is used to cooperate with the lock tongue assembly so that the lock tongue of the lock tongue assembly passes through the lock housing assembly;

[0028] A limit piece is rotatably mounted on the lock housing assembly, the limit piece has a first matching portion and a second matching portion, the limit piece has a limiting working position and an unlocking working position, when the limit piece is in the limiting working position, the matching portion is used to abut against the connecting block to limit the movement of the lock tongue assembly toward the inside of the lock housing assembly, when the limit piece is in the unlocking working position, the matching portion no longer limits the connecting block, the lock tongue assembly can move toward the inside of the lock housing assembly, and the limit piece can be reset to the limiting working position when not subject to external force;

[0029] An oblique lock tongue assembly is slidably arranged on the lock housing assembly, and the oblique lock tongue assembly comprises a connecting member and an oblique lock tongue rotatably mounted on the connecting member, wherein the connecting member has a pressing portion, and the pressing portion is used to cooperate with the second matching portion;

[0030] The oblique lock tongue reset member is installed on the lock housing assembly and is used to cooperate with the oblique lock tongue assembly to make the oblique tongue of the oblique lock tongue assembly pass through the lock housing assembly. When the oblique tongue of the oblique lock tongue assembly passes through the lock housing assembly, the pressing portion abuts against the second matching portion to drive the limiting member to rotate to the unlocking working position.

[0031] The first paddle is movably arranged on the lock housing assembly, and is used for abutting and cooperating with the limiting member. The limiting member can be rotated from the limiting working position to the unlocking working position through the movement of the first paddle; the first paddle has a first pressure-bearing portion and a second pressure-bearing portion, the first convex portion is used for cooperating with the first pressure-bearing portion, and the second driving portion is used for cooperating with the second pressure-bearing portion. After the first pressure-bearing portion or the second pressure-bearing portion is pressed and moved, it can move toward one side of the limiting member, so that the limiting member is switched to the unlocking working position.

[0032] The working principle of the locking and unlocking mechanism of the lock tongue: in the closed state, the oblique lock tongue assembly is pressed into the lock housing assembly. At this time, the oblique lock tongue assembly does not limit the limiter, and the limiter is in the limiter working position, that is, the first matching part can abut against the connecting block, limiting the lock tongue assembly from moving inside the lock housing assembly, that is, the lock tongue is locked and cannot be retracted into the lock housing assembly. When the first paddle is activated by force, the limiter can be triggered to rotate the limiter to the unlocking working position. At this time, the first matching part no longer limits the connecting block, and the lock tongue assembly can move inside the lock housing assembly. In addition, even if the oblique lock tongue assembly is pressed by mistake (to retract the oblique lock tongue into the lock housing assembly) in the open door state, after being released, the oblique lock tongue assembly can be reset under the action of the oblique lock tongue reset member, automatically rotating the limiter to the unlocking working position. This matching form greatly improves stability and is not afraid of misoperation.

[0033] The locking and unlocking mechanism of the lock tongue of the present application has a simple locking and unlocking process and good reliability and stability.

[0034] In one embodiment of the present invention, the locking and unlocking mechanism of the lock tongue also includes a limit member reset member installed on the lock housing assembly, and the limit member reset member is used to cooperate with the limit member so that the limit member can be reset to the limit working position when not subject to external force; the first paddle is slidably installed on the lock housing assembly.

[0035] The limiter reset member can provide force to reset the limiter, thus ensuring the reliable operation of the limiter.

[0036] In one embodiment of the present invention, a control panel for controlling the operation of the electric drive mechanism is further included, and the transmission mechanism further includes a positioning assembly, and the positioning assembly includes:

[0037] A positioning gear is rotatably mounted on the lock housing assembly and meshes with the driving member. The positioning gear has a triggering portion.

[0038] A positioning sensor is provided on the lock housing assembly and is electrically connected to the control board. The positioning sensor is used to sense the triggering portion, and the positioning sensor is a micro switch, a Hall switch or an optical switch.

[0039] By providing the positioning gear and the positioning sensor, the position of the driving member can be reliably determined, so as to ensure that after the locking tongue portion of the main locking tongue penetrates out of the lock housing assembly, the driving member can be accurately reset. With this structural form of the positioning assembly, compared with other methods, the accuracy and reliability are higher, and the assembly and debugging are also more convenient. In this embodiment, the triggering portion is the second convex portion, and in actual use, it can also be other structures.

[0040] In one embodiment of the present invention, the driving member is a driving gear, and the motor driving mechanism includes a driving motor, and the driving motor directly or drives the driving member to rotate through a gear structure.

[0041] In actual use, the electric driving mechanism may include a transmission gear. The transmission gear includes a first bevel gear and a first tooth that meshes with the driving member. A second bevel gear that meshes with the first bevel gear is provided on the output shaft of the driving motor.

[0042] In one embodiment of the present invention, the transmission mechanism further includes an assisting torsion spring, and the assisting torsion spring is used to assist the main locking tongue to penetrate out of the lock housing assembly or retract into the lock housing assembly after the main locking tongue block passes the critical point.

[0043] In one embodiment of the present invention, it further includes an anti-theft locking tongue mechanism. The anti-theft locking tongue mechanism includes an anti-theft locking tongue, an anti-theft lock positioning block, an anti-theft lock locking mechanism and an anti-theft lock return spring. The anti-theft locking tongue can penetrate through the lock housing assembly; one end of the anti-theft lock positioning block is connected to the anti-theft locking tongue, and the other end is connected to the anti-theft lock return spring, and the anti-theft lock positioning block can move relative to the lock housing assembly; the anti-theft lock locking mechanism is installed in the lock housing assembly and is in transmission cooperation with the anti-theft lock positioning block.

[0044] The beneficial effect of the present invention is that the driving member can be driven to rotate through the electric driving mechanism, so that the first transmission portion can rotate synchronously. Under the action of the first transmission portion, the main locking tongue can be driven to penetrate out of the lock housing assembly or retract into the lock housing assembly.

DETAILED DESCRIPTION

[0065] The present invention is described in detail below in conjunction with the accompanying drawings.

[0066] like Figures 1 - 18As shown, a fully automatic lock 100 includes a lock housing assembly 10, and mounted on the lock housing assembly 10 are:

[0067] A locking and unlocking mechanism 30 for the lock tongue;

[0068] A main lock tongue 20, slidably disposed on the lock housing assembly 10, and the main lock tongue 20 includes a lock tongue portion 21 and a positioning portion 22;

[0069] A transmission mechanism 50, which is used to cooperate with the locking and unlocking mechanism 30 of the lock tongue to unlock the locking and unlocking mechanism 30 of the lock tongue, and is also used to cooperate with the main lock tongue 20 to enable the lock tongue portion 21 to penetrate out of the lock housing assembly 10 or retract into the lock housing assembly 10; the transmission mechanism 50 includes a driving member 55 and a main lock tongue dial block 56, the driving member 55 is rotatably mounted on the lock housing assembly 10, the main lock tongue dial block 56 is rotatably mounted on the lock housing assembly 10 and cooperates with the driving member 55, the driving member 55 can drive the main lock tongue dial block 56 to rotate, the main lock tongue dial block 56 has a first transmission portion 561 that cooperates with the positioning portion 22 of the main lock tongue 20, when the main lock tongue dial block 56 rotates, the main lock tongue 20 can be driven to slide through the first transmission portion 561, so that the lock tongue portion 21 penetrates out of the lock housing assembly 10 or retracts into the lock housing assembly 10; the driving member 55 also has a first convex portion 551, when the driving member 55 drives the main lock tongue dial block 56 to rotate and the main lock tongue 20 retracts into the lock housing assembly 10, the first convex portion 551 is used to cooperate with the locking and unlocking mechanism 30 of the lock tongue to unlock the locking and unlocking mechanism 30 of the lock tongue;

[0070] An electric drive mechanism 40, which is used to drive the driving member 55 to rotate.

[0071] The electric drive mechanism 40 can drive the driving member 55 to rotate, so that the first transmission portion 561 can rotate synchronously. Under the action of the first transmission portion 561, the main lock tongue 20 can be driven to penetrate out of the lock housing assembly 10 or retract into the lock housing assembly 10.

[0072] In the closed door state, in addition to opening the main lock tongue 20, the locking and unlocking mechanism 30 of the lock tongue also needs to be unlocked. In the action that the driving member 55 drives the main lock tongue dial block 56 to rotate and the main lock tongue 20 retracts into the lock housing assembly 10, the first convex portion 551 of the driving member 55 can cooperate with the locking and unlocking mechanism 30 of the lock tongue to unlock the locking and unlocking mechanism 30 of the lock tongue, so that the door opening operation can be realized. The transmission mechanism 50 of the present application has a simple and reliable structure.

[0073] Such as Figure 18As shown, in this embodiment, the positioning portion 22 has a first notch 221. The first notch 221 has a first side wall 223 and a second side wall 224. The first side wall 223 is close to the locking tongue portion 21, and the second side wall 224 is away from the locking tongue portion 21. The first transmission portion 561 cooperates with the first notch 221 to drive the main locking tongue 20 to slide through the first notch 221. When the locking tongue portion 21 of the main locking tongue 20 penetrates out of the lock housing assembly 10, the first transmission portion 561 abuts against the first side wall 223. When the locking tongue portion 21 of the main locking tongue 20 retracts into the lock housing assembly 10, the first transmission portion 561 abuts against the second side wall 224. The second side wall 224 has a buffer area 2241. After the locking tongue portion 21 of the main locking tongue 20 retracts into the lock housing assembly 10, the first transmission portion 561 can continue to rotate in the buffer area 2241. When the driving member 55 drives the first transmission portion 561 to rotate and the locking tongue portion 21 retracts into the lock housing assembly 10, the driving member 55 continues to rotate. While the first transmission portion 561 idles in the buffer area 2241, the first convex portion 551 cooperates with the locking and unlocking mechanism 30 of the locking tongue to unlock the locking and unlocking mechanism 30 of the locking tongue.

[0074] The buffer area 2241 provided on the second side wall 224 is to provide time for the cooperation between the first convex portion 551 and the locking and unlocking mechanism 30 of the locking tongue, so as to ensure that the locking and unlocking mechanism 30 of the locking tongue will not be unlocked when unlocking the main locking tongue 20, effectively ensuring that the main locking tongue 20 can reliably slide into the lock housing assembly 10. In actual use, the buffer area 2241 can be an arc surface.

[0075] As Figure 17 shown, in this embodiment, the main locking tongue dial 56 and the driving member 55 have the same rotation axis, and there is an idling structure between the main locking tongue dial 56 and the driving member 55;

[0076] The idling structure includes a first fitting block 104 provided on the main locking tongue dial 56 and a second fitting block 105 provided on the driving member 55. The main locking tongue dial 56 can idle relative to the driving member 55 by a set angle. When the driving member 55 rotates and the second fitting block 105 abuts against the first fitting block 104, the driving member 55 can drive the main locking tongue dial 56 to rotate synchronously when continuing to rotate in the same direction;

[0077] After the locking tongue portion 21 of the main locking tongue 20 penetrates out of the lock housing assembly 10, the driving member 55 can be reset. When the main locking tongue dial 56 is driven by other mechanisms, the main locking tongue dial 56 can idle relative to the driving member 55 and unlock the main locking tongue 20;

[0078] The full-automatic lock further includes a mechanical unlocking mechanism, which is used to drive the main locking tongue dial 56 to idle to retract the locking tongue portion 21 into the lock housing assembly 10 in the state where the locking tongue portion 21 penetrates out of the lock housing assembly 10.

[0079] Setting up an idling structure can prevent the main lock tongue dial block 56 from exerting a force on the driving part 55 when the mechanical unlocking mechanism works, ensuring the reliable and smooth operation of the mechanical unlocking mechanism.

[0080] As Figure 16 shown, in this embodiment, the mechanical unlocking mechanism includes:

[0081] A mechanical dial block 43, rotatably installed on the lock housing assembly 10. The mechanical dial block 43 has a slot 431, and the mechanical dial block 43 has a first driving part 46 and a second driving part 106;

[0082] A second dial 57, rotatably installed on the lock housing assembly 10. One end of the second dial 57 is engaged with the first driving part 46, and the other end is engaged with the main lock tongue dial block 56. When the mechanical dial block 43 rotates, the second dial 57 can be driven to rotate through the first driving part 46. The rotation of the second dial 57 drives the main lock tongue dial block 56 to idle, unlocking the main lock tongue 20. The second driving part 106 is used to cooperate with the locking and unlocking mechanism 30 of the lock tongue after the second dial 57 drives the main lock tongue 20 to unlock the main lock tongue 20, unlocking the locking and unlocking mechanism 30 of the lock tongue.

[0083] When the "main lock tongue dial block 56 unlocks the main lock tongue 20", it means that the main lock tongue dial block 56 drives the main lock tongue 20 to slide into the lock housing assembly 10.

[0084] The slot 431 can cooperate with a rod, such as a square rod. The mechanical dial block 43 can be driven to rotate through the square rod. In actual use, the doorknob inside the door can drive the mechanical dial block 43 to rotate through the square rod. In actual use, the mechanical unlocking mechanism further includes a first reset elastic member 45.

[0085] As Figures 1 - 15 shown, in this embodiment, the locking and unlocking mechanism 30 of the lock tongue includes:

[0086] A lock tongue assembly, slidably arranged on the lock housing assembly 10. The lock tongue assembly includes a connecting block 3211 and a lock tongue 31 rotatably installed on the connecting block 3211;

[0087] A lock tongue assembly reset member 324, installed on the lock housing assembly 10, for cooperating with the lock tongue assembly to make the lock tongue of the lock tongue assembly protrude from the lock housing assembly 10;

[0088] The limiting member 3212 is rotatably mounted on the lock housing assembly 10. The limiting member 3212 has a first matching portion 3214 and a second matching portion 3216. The limiting member 3212 has a limiting working position and an unlocking working position. When the limiting member 3212 is in the limiting working position, the matching portion is used to abut against the connecting block 3211 to limit the movement of the bolt assembly toward the inside of the lock housing assembly 10. When the limiting member 3212 is in the unlocking working position, the matching portion no longer limits the connecting block 3211, and the bolt assembly can move toward the inside of the lock housing assembly 10. The limiting member 3212 can be reset to the limiting working position when not subject to external force.

[0089] The oblique locking tongue assembly is slidably disposed on the lock housing assembly 10. The locking tongue assembly includes a connecting member 322 and an oblique locking tongue 80 rotatably mounted on the connecting member 322. The connecting member 322 has a pressing portion 3221, and the pressing portion 3221 is used to cooperate with the second matching portion 3216.

[0090] The oblique lock tongue reset member 323 is installed on the lock housing assembly 10, and is used to cooperate with the oblique lock tongue assembly to make the oblique tongue of the oblique lock tongue assembly pass through the lock housing assembly 10. When the oblique tongue of the oblique lock tongue assembly passes through the lock housing assembly 10, the pressing portion 3221 abuts against the second matching portion 3216, driving the limiting member 3212 to rotate to the unlocking working position.

[0091] like Figure 16 As shown, the locking and unlocking mechanism 30 of the lock tongue also includes a first paddle 60, which is movably arranged on the lock shell assembly 10, and is used to abut and cooperate with the limiting member 3212. Through the movement of the first paddle 60, the limiting member 3212 can be rotated from the limiting working position to the unlocking working position; the first paddle 60 has a first pressure-bearing portion 101 and a second pressure-bearing portion 102, the first convex portion 551 is used to cooperate with the first pressure-bearing portion 101, and the second driving portion 106 is used to cooperate with the second pressure-bearing portion 102. After the first pressure-bearing portion 101 or the second pressure-bearing portion 102 is pressed and moved, it can move toward the side of the limiting member 3212, so that the limiting member 3212 is switched to the unlocking working position.

[0092] Working principle of the locking and unlocking mechanism 30 of the locking tongue: In the closed door state, the inclined locking tongue assembly is pressed into the lock housing assembly 10. At this time, the inclined locking tongue assembly does not limit the limiting member 3212, and the limiting member 3212 is in the limiting working position, that is, the first engaging portion 3214 can abut against the connecting block 3211 to limit the movement of the locking tongue assembly towards the inner side of the lock housing assembly 10. That is, the locking tongue 31 is locked and cannot retract into the lock housing assembly 10. When the first dial 60 is stressed and moves, it can trigger the limiting member 3212 to rotate the limiting member 3212 to the unlocking working position. At this time, the first engaging portion 3214 no longer limits the connecting block 3211, and the locking tongue assembly can move towards the inner side of the lock housing assembly 10. In addition, even in the open door state, if the inclined locking tongue assembly is accidentally pressed (causing the inclined locking tongue 80 to retract into the lock housing assembly 10), when released, the inclined locking tongue assembly can be reset under the action of the inclined locking tongue return member 323, automatically rotating the limiting member 3212 to the unlocking working position. This form of cooperation greatly improves the stability and is not afraid of misoperation.

[0093] The locking and unlocking process of the locking and unlocking mechanism 30 of the locking tongue in this application is simple, and the reliability and stability are good.

[0094] In this embodiment, the locking and unlocking mechanism 30 of the locking tongue further includes a limiting member return member 3242 installed on the lock housing assembly 10. The limiting member return member 3242 is used to cooperate with the limiting member 3212 to enable the limiting member 3212 to return to the limiting working position when not subjected to external force; the first dial 60 is slidably installed on the lock housing assembly 10. The limiting member return member 3242 can provide a force to reset the limiting member 3212 to ensure the reliable operation of the limiting member 3212.

[0095] In other embodiments, in this embodiment, the center of gravity of the limiting member 3212 is not on the rotation axis of the limiting member 3212, and the limiting member 3212 can return to the limiting working position by its own gravity. This method can omit the limiting member return member 3242 and simplify the structure.

[0096] In this embodiment, the locking tongue return member 324 is a spring or a torsion spring; the limiting member return member 3242 is a spring or a torsion spring; the inclined locking tongue return member 323 is a spring or a torsion spring.

[0097] In this embodiment, the first engaging portion 3214 is a rotating shaft rotatably installed on the limiting member 3212. The first engaging portion 3214 is a rotating shaft, and this method can reduce the friction force and facilitate the position switching of the first engaging portion 3214.

[0098] In this embodiment, the locking tongue 31 is a two-way locking tongue 31.

[0099] In this embodiment, it further includes a micro switch 103 installed on the lock housing assembly 10. The micro switch 103 is used to cooperate with the limiting member 3212 or the connecting member 322.

[0100] As Figure 17 shown, in this embodiment, it further includes a control board 113 for controlling the operation of the electric drive mechanism 40. The transmission mechanism 50 further includes a positioning component, and the positioning component includes:

[0101] A positioning gear 107, rotatably mounted on the lock housing assembly 10, meshing with the driving member 55, and having a triggering portion 109 thereon;

[0102] A positioning sensor 108, disposed on the lock housing assembly 10 and electrically connected to the control board 113. The positioning sensor 108 is used to sense the triggering portion 109, and the positioning sensor 108 is a microswitch 103, a Hall switch or an optical switch.

[0103] By providing the positioning gear 107 and the positioning sensor 108, the position of the driving member 55 can be reliably determined, so as to ensure that after the locking tongue portion 21 of the main locking tongue 20 penetrates the lock housing assembly 10, the driving member 55 can be accurately reset. With this structural form of the positioning component, compared with other methods, the accuracy and reliability are higher, and the assembly and debugging are also more convenient. In this embodiment, the triggering portion 109 is a second convex portion, and in actual application, it can also be other structures.

[0104] In this embodiment, the driving member 55 is a driving gear, and the motor drive mechanism includes a driving motor 41, and the driving motor 41 directly or drives the driving member 55 to rotate through a gear structure. As Figure 16 shown, in this embodiment, the electric drive mechanism 40 may include a transmission gear 53. The transmission gear 53 includes a first bevel gear 110 and a first tooth 111 meshing with the driving member 55, and the output shaft of the driving motor 41 has a second bevel gear 42 meshing with the first bevel gear 110.

[0105] As Figure 16 shown, in this embodiment, the transmission mechanism 50 further includes a boosting torsion spring 112, and the boosting torsion spring 112 is used to assist the main locking tongue 20 to penetrate or retract into the lock housing assembly 10 after the main locking tongue block 56 passes the critical point.

[0106] As Figure 11 、 12 and shown in FIG. 14, in this embodiment, it further includes an anti-theft locking tongue mechanism 70. The anti-theft locking tongue mechanism includes an anti-theft locking tongue 71, an anti-theft lock positioning block 72, an anti-theft lock locking mechanism 73 and an anti-theft lock return spring 74. The anti-theft locking tongue 71 can pass through the lock housing assembly 10; one end of the anti-theft lock positioning block is connected to the anti-theft locking tongue, and the other end is connected to the anti-theft lock return spring, and the anti-theft lock positioning block can move relative to the lock housing assembly 10; the anti-theft lock locking mechanism is installed in the lock housing assembly 10 and is in transmission cooperation with the anti-theft lock positioning block.

[0107] AsFigure 11 As shown, the insurance lock locking mechanism 73 includes: an insurance lock shifting block 731, a second slot 732, and an insurance lock transmission member 733; the insurance lock shifting block 731 is installed on the lock housing assembly 10 and can rotate relative to the lock housing assembly 10; the second slot 732 is opened on the insurance lock shifting block 731 for an external core to be inserted and rotate the insurance lock shifting block 731; the insurance lock transmission member 733 is sleeved on the insurance lock shifting block 731. When the user rotates the insurance lock shifting block 731 with the core, the insurance lock transmission member 733 is driven and is in transmission cooperation with the insurance lock positioning block 72.

[0108] As Figure 2 and 3 shown, the side of the lock housing assembly 10 facing the outer door frame is provided with a main lock tongue through hole 11, a bi-directional lock tongue through hole 14, an inclined lock tongue through hole 15, and an insurance lock tongue through hole 16; a buckle plate 90 adapted to the lock housing assembly 10 is installed on the outer door frame. On the buckle plate 90, there are provided: a main lock tongue corresponding hole 91 adapted to the main lock tongue through hole 11, a bi-directional lock tongue corresponding hole 92 adapted to the bi-directional lock tongue through hole 14, and an insurance lock tongue corresponding hole 93 adapted to the insurance lock tongue through hole 16.

[0109] It can be understood that there is no opening on the buckle plate 90 adapted to the inclined lock tongue 80, that is: when the door equipped with the full-automatic lock 100 is in the closed state, the inclined lock tongue 90 is squeezed into the interior of the lock housing assembly 10. In addition, the lock housing assembly 10 is composed of a panel (not labeled in the figure) and a lock housing (not labeled in the figure).

[0110] As Figure 4 and 5 shown, a second cylinder 12 is installed inside the lock housing assembly 10; the positioning block 22 has a first sliding opening 222. The first sliding opening 222 is sleeved on the second cylinder 12 so as to limit the moving direction and range of the connecting block 22 based on the limiting cooperation between the first sliding hole 222 and the second cylinder 12.

[0111] As Figure 9 shown, the limiting member 3212 includes: a first limiting plate 3213 and a second limiting plate 3215, and a first matching portion 3214 is installed between the first limiting plate 3213 and the second limiting plate 3215. Among them, a second matching portion 3216 is formed on the side of the first limiting plate 3213 facing the connecting member 322, and the second matching portion 3216 is in transmission cooperation with the connecting member 322.

[0112] The second limit plate 3215 forms a limit abutment portion 3217 and a transmission abutment portion 3218 on one side of the connecting member 322. The limit abutment portion 3217 abuts against a convex body (not shown) formed inside the lock housing assembly 10 to limit the rotation range of the limit member 3212, that is, when the limit member 3212 rotates toward the position where the connecting member 322 is located, the limit abutment portion 3217 abuts against the convex body installed in the lock housing assembly 10, and the limit member 3212 stops rotating. When the first paddle 60 moves toward the limit member 3212, it abuts against the transmission abutment portion 3218, and can also push the transmission abutment portion 3218 to rotate the limit member 3212, thereby staggering the left end of the limit member 3212 and the right end of the connecting block 3211.

[0113] In addition, a first limiting column 13 is provided on the lock housing assembly 10, and the first limiting column 13 is located on the side of the second limiting plate 3215 facing away from the first side surface 17. When the limiting member 3212 rotates toward the first paddle 60, the second limiting plate 3215 can abut against the first limiting column 13 and prevent the limiting member 3212 from further rotating, thereby limiting the rotation range of the limiting member 3212.

[0114] like Figure 10 As shown, a spring connection portion 3222 is formed on the connecting member 322, and the connecting member 322 is connected to the oblique lock tongue reset member 323 through the spring connection portion 3222. The oblique lock tongue reset member 323 is a reset spring, one end of which is connected to the connecting member 322, and the other end is connected to the second side 18 of the lock housing assembly 10.

[0115] like Figure 6 As shown, the limiting member 3212 is installed at the sixth column 19 of the lock housing assembly and can rotate around the sixth column 19.

[0116] like Figure 7 As shown, one end of the first resetting elastic member is connected to the fourth column 47, and the other end is hooked with the through hole 441 on the mechanical shifting block.

[0117] like Figure 4 As shown, the transmission mechanism 50 further includes: a first column 51 , a rotating shaft 52 and a main lock tongue driving shaft 54 ​​.

[0118] like Figure 4 As shown, the second paddle 57 has a curved portion 571 , and the curved portion 571 of the second paddle 57 abuts against the main lock tongue paddle block 56 and drives the main lock tongue paddle block 56 to rotate.

[0119] like Figure 4 As shown, the main lock tongue block 56 has a limiting portion 562, which can abut against a second protrusion (not shown) installed in the lock housing assembly 10, thereby preventing the main lock tongue block 56 from continuing to rotate.

[0120] Taking the locking process of the fully automatic lock 100 as an example, it can be described in detail as follows:

[0121] 1. As Figure 12 shown, when the door equipped with the fully automatic lock 100 is in the open state, the locking tongue 31 and the diagonal locking tongue 80 extend out of the lock housing assembly 10, and the locking tongue part 21 and the safety locking tongue 71 are located inside the lock housing assembly 10; specifically:

[0122] The locking tongue part 21 is located inside the lock housing assembly 10, and the first transmission part 561 of the main locking tongue dial block 56 abuts against the second side wall of the first notch 221;

[0123] The locking tongue 31 completely extends out of the lock housing assembly 10, one end of the connecting block 3211 contacts the side surface of the lock housing assembly 10, and the first matching part of the limiting part 3212 no longer limits the connecting block 3211;

[0124] The diagonal locking tongue 80 completely extends out of the lock housing assembly 10, the connecting piece 322 is away from the second side surface 18, and the pressing part 3221 abuts against the first abutting part 3216;

[0125] The safety locking tongue 71 is located inside the lock housing assembly 10, one end of the safety lock positioning block 72 is close to the second side surface 18, the fifth cylinder 75 is located on the left side of the second sliding opening 722, the end part of the safety lock dial block 731 abuts against the end part of the second notch 721 close to the second side surface 18, and the safety lock return spring 74 is in a relaxed state.

[0126] 2. When the user closes the door, the locking tongue 31 and the diagonal locking tongue 80 are squeezed by the door frame and will retract into the lock housing assembly 10, as Figure 13 shown. The specific process is as follows:

[0127] The locking tongue 31 moves towards the inside of the lock housing assembly 10 under the action of the door frame, and drives the connecting block 3211 to move towards the second side surface 18. The final state is that the double-sided locking tongue 31 is located inside the lock housing assembly 10;

[0128] The diagonal locking tongue 80 moves towards the inside of the lock housing assembly 10 under the action of the door frame, and drives the connecting piece 322 to move towards the second side surface 18. The diagonal locking tongue return piece 323 is in a compressed state, and the pressing part 3221 does not contact the second matching part 3216.

[0129] 3. When the door is completely closed, the main locking tongue 21, the locking tongue 31 and the safety locking tongue 71 are all in the locked state, as Figure 14 shown. The specific process is as follows:

[0130] When the door is fully closed, the locking tongue 31 is exactly opposite to the two-way locking tongue corresponding hole 91, and the external force acting on the two-way locking tongue 31 disappears; the locking tongue assembly reset member 324 pushes the connecting block 3211 to move towards the left based on the acting force generated by its own deformation, and drives the two-way locking tongue 31 to move towards the left; when the connecting block 3211 moves to the left side of the lock housing assembly 10, the connecting block 3211 disengages from the limiting member 3212; the limiting member reset member 3242 drives the limiting member 3212 to rotate counterclockwise based on the acting force generated by its own deformation, and rotates to a position opposite to the end of the connecting block 3211;

[0131] The left side of the inclined locking tongue 80 abuts against the buckle plate 90 and is still located inside the lock housing assembly 10, and the inclined locking tongue reset member 323 is still in a compressed state;

[0132] When the door is fully closed, the driving motor 41 starts and drives the second bevel gear 42 to rotate. The second bevel gear cooperates with the first bevel gear to make the transmission gear 53 rotate clockwise, and then drives the driving member 55 to rotate in sequence, so that the main locking tongue dial 56 rotates counterclockwise; further pushes the positioning block 22 and the locking tongue part 21 to move towards the left, so that the locking tongue part 21 completely extends out of the lock housing assembly 10; the final state of the main locking tongue 20 is: the locking tongue part 21 extends out of the lock housing assembly 10 and extends into the main locking tongue corresponding hole 91 at the buckle plate 90, the first transmission part 561 abuts against the first side wall of the notch 221, and the right side of the first sliding opening 221 contacts the second cylinder 12;

[0133] The user inserts the core into the second slot 732 and rotates the safety locking tongue dial 731 counterclockwise, and then drives the safety lock transmission member 733 to rotate counterclockwise; when the safety lock transmission member 733 rotates counterclockwise, the end thereof abuts against the left end of the second notch 721, and pushes the safety lock positioning block 72 and the safety locking tongue 71 to move towards the left, and stretches the safety lock return spring 74; the final state of the safety locking tongue mechanism 70 is: the safety locking tongue 71 extends out of the lock housing assembly 10 and extends into the safety locking tongue corresponding hole 93 on the buckle plate 90, the safety lock dial 731 abuts against the safety lock positioning block 72, the safety lock return spring is in a stretched state, and the fifth cylinder 75 is located on the right side of the second sliding opening 722.

[0134] It can be understood that the unlocking process of the full-automatic lock 100 in this embodiment is:

[0135] The driving motor 41 starts to drive the driving member to rotate, and then makes the main locking tongue dial 56 rotate clockwise; the first transmission part 561 rotates counterclockwise and abuts against the second side wall of the first notch 221, and then pushes the main locking tongue 20 to move towards the right (i.e., the second side 18);

[0136] In addition, when the second transmission gear 55 rotates clockwise, it drives the first convex portion 551 to rotate clockwise and pushes the first paddle 60 to move upward; furthermore, the end of the first paddle 60 abuts against the transmission abutting portion 3218 and pushes the limiting member 3212 to rotate clockwise, so that the connecting block 3211 and the limiting member 3212 are in a staggered state; when the double-sided lock tongue 31 is externally squeezed, it can push the connecting block 3211 to move towards the right; when the door panel is completely separated from the door frame, the external force on the double-sided lock tongue 31 disappears, and the double-sided lock tongue 31 moves towards the left, and then the double-sided lock tongue 31 extends out of the lock housing assembly 10;

[0137] When the diagonal lock tongue 80 disengages from the door frame, the extrusion force from the door frame disappears. Furthermore, the diagonal lock tongue return spring 323 will return from the compressed state to the relaxed state, and drive the connecting member 322 and the diagonal lock tongue 80 to move towards the left, so that the diagonal lock tongue 80 extends out of the lock housing assembly 10, and also makes the pressing portion 3221 abut against the second mating portion 3216, and then makes the limiting member 3212 and the connecting block 3211 staggered, so that the double-sided lock tongue 31 can retract into the lock housing assembly 10 based on an external force.

[0138] The above are only the preferred embodiments of the present invention, and thus do not limit the patent protection scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention, directly or indirectly applied in other related technical fields, shall be equally included in the protection scope of the present invention.
