[0030] The following further describes the embodiments of the present invention with reference to the accompanying drawings: As Figure 1 shown in combination with Figures 2 - 13 an electronic lock includes a housing 1 and a main lock tongue 2, and further includes: a main lock tongue push piece 3 disposed inside the housing 1, and the main lock tongue 2 is disposed on the main lock tongue push piece 3 and is driven by the main lock tongue push piece 3 to reciprocate; a transmission mechanism 4 disposed on the housing 1 and connected to the main lock tongue push piece 3 for driving the main lock tongue push piece 3 to act; a tongue-turning structure 5, and the tongue-turning structure 5 includes a tongue-turning body 52; an electric operating mechanism 6 connected to the transmission mechanism 4 for driving the transmission mechanism 4 to act, and the electric operating mechanism 6 includes a power source 61, a clutch assembly 62 and a gear assembly 63, and the clutch assembly 62 has a first position where it drives the transmission mechanism 4 to act through the gear assembly 63 when engaged and a second position when separated; The handle operating mechanism 7 is connected to the transmission mechanism 4 and is used to drive the transmission mechanism 4 to move and make the clutch assembly 62 in its second position to realize the handle priority unlocking; The key operating mechanism 8 is connected to the transmission mechanism 4, and is used to drive the transmission mechanism 4 to move and make the clutch assembly 62 in its second position to realize key priority unlocking. The beneficial effects of the present invention are that the electric operating mechanism, the electric operating mechanism, and the key operating mechanism can all drive the main lock tongue push piece to move through the transmission mechanism to realize the interlocking and unlocking of the main lock tongue, the structure is simple, the transmission is convenient and reliable, the product volume is small, and the clutch assembly is set, which can realize separation and engagement simply and quickly, and realize fast manual and automatic switching. The product structure is simple, the parts are few, the performance is reliable, the assembly difficulty is low, and the structure occupies less space in the shell, which is convenient for the assembly of other parts.

[0031] The transmission mechanism 4 includes a driving gear 41, a transmission member 42 and a main lock tongue paddle 43. The gear assembly 63 is meshed with the driving gear 41 and is used to drive the driving gear 41 to rotate. The driving gear 41 drives the main lock tongue paddle 43 to rotate through the transmission member 42. The main lock tongue paddle 43 is connected to the main lock tongue push piece 3 and is used to drive the main lock tongue push piece 3 to reciprocate. Specifically, when the power source is in action, it can drive the gear assembly to rotate, the gear assembly drives the driving gear to rotate, the driving gear drives the transmission member to rotate, the transmission member drives the main lock tongue paddle to rotate, and the main lock tongue paddle drives the main lock tongue push piece to reciprocate linearly, thereby realizing the interlocking (closing the door) and unlocking and opening the door of the main lock tongue.

[0032] The driving gear 41, the transmission member 42 and the main lock tongue paddle 43 are all sleeved on the transmission shaft 44; the main lock tongue push piece 3 is provided with a guide groove 31 and an interlocking groove 32, and the transmission shaft 44 is set through the guide groove 31 and makes the main lock tongue push piece 3 reciprocate linearly; the main lock tongue paddle 43 is provided with a driving shaft 45, and the driving shaft 45 is inserted into the interlocking groove 32 and used to drive the main lock tongue push piece 3 to move, and the interlocking groove 32 is set in a bent manner. The driving gear, the transmission member, the main lock tongue paddle, and the key transmission plate are all sleeved on the transmission shaft, and the overall volume of the product is small, the space in the shell is reasonably used, and the structure is compact. The setting of the guide groove makes the main lock tongue push piece run smoothly and the structure is simple. The setting of the interlocking groove makes the interlocking of the main lock tongue push piece reliable. Specifically, the interlocking groove is bent, one part of which is horizontally set and the other part is obliquely set. The obliquely set part can be set in an arc shape, so that the interlocking groove can be connected with the driving shaft when closing the door to prevent the main lock tongue from being tilted and opened.

[0033] The described transmission member 42 is provided with a first transmission block 421 and a second transmission block 422. The main lock tongue dial 43 and the drive gear 41 are respectively arranged on the upper and lower sides of the transmission member 42. The drive gear 41 is provided with a first drive groove 411. The first transmission block 421 is inserted into the first drive groove 411. The first drive groove 411 reserves a rotation space required when the first transmission block 421 is driven by the handle operating mechanism 7 and / or the key operating mechanism 8. The main lock tongue dial 43 is provided with a second drive groove 431. The second transmission block 422 is inserted into the second drive groove 431 and drives the main lock tongue dial 43 to rotate through the second drive groove 431. Specifically, the setting of the first drive groove can reliably drive the transmission member to act when the key operating mechanism or the handle operating mechanism is driven, and will not affect the gear assembly, providing a rotation stroke for the transmission member. When the electric operating mechanism acts, it can quickly drive the transmission member and the main lock tongue dial to act through the drive gear. Specifically, the second drive groove is also slightly larger than the second transmission block. Such a structure avoids misoperation of the electric operating mechanism or over-movement during transmission, which may damage components and affect the product life, and provides a more reasonable transmission space.

[0034] The described handle operating mechanism 7 includes a handle operating shaft 71 and a handle operating plate 72. The handle operating shaft 71 is provided with a handle drive block 711. The handle drive block 711 is connected to the transmission member 42 through the handle operating plate 72 and is used to drive the transmission member 42 to rotate. Specifically, the handle operating plate 72 and the transmission member 42 are engaged through a rotating tooth set. The handle operating shaft 71 is provided with a handle clutch block 712 for driving the clutch assembly 62 to disengage. The handle operating plate 72 is provided with a handle unlocking block 721 for driving the tongue unlocking piece 56 to rotate so that the tongue body 52 is unlocked. In this way, the handle operating shaft can reliably drive the handle operating plate to act through the handle drive block. Taking opening the door as an example, since the handle operating plate is engaged with the transmission member, at this time, it can drive the transmission member to rotate, thereby driving the main lock tongue push plate to reciprocate. When the handle operating shaft rotates, the clutch assembly will be disengaged, thus realizing handle priority. At the same time, the handle unlocking block can unlock the tongue limiting piece through the tongue unlocking piece, so that the tongue can move freely, facilitating door opening.

[0035] The key operating mechanism 8 includes a key operating member 81 and a key transmission plate 82. The key transmission plate 82 is sleeved on the transmission member 42. The key transmission plate 82 is provided with a first meshing portion 821, a second meshing portion 822 and a hollow hole 823. The key operating member 81 is meshed with the first meshing portion 821, and the second meshing portion 822 is meshed with the key clutch plate 83. The key clutch plate 83 is provided with a key clutch drive block 831 for driving the clutch assembly 62 to separate. The first meshing portion 821 and the second meshing portion 822 are arranged at different heights. The transmission member 42 is arranged above the second meshing portion 822 and its horizontal height is flush with the first meshing portion 821. Specifically, the first transmission block is arranged in the first driving groove through the hollow hole. Such a structure enables the key operating mechanism to reliably drive the transmission member to move and realize the movement of the main lock tongue. Take door opening as an example. When the key operating member rotates, the first meshing part rotates counterclockwise, so the second meshing part rotates counterclockwise at the same time. At this time, the key clutch plate rotates clockwise, driving the clutch paddle to rotate, so that the clutch paddle wheel is separated, avoiding damage to parts and realizing key priority. At the same time, because the transmission member is engaged with the handle operating plate, the handle unlocking block on the handle operating plate can unlock the tongue limit plate through the tongue unlocking piece, so that the tongue can move freely, which is convenient for opening the door.

[0036] The flap structure 5 comprises: The flap stopper 53 is disposed in the housing 1 and is used to limit the flap body 52 from turning over. The flap body 52 has a first state of linear reciprocating motion relative to the housing 1 and a second state of relative rotation when opened. When the flap body 52 is limited and turned over by the flap stopper 53, it slides linearly with the flap stopper 53. The limiting elastic member 54 is disposed in the housing 1, connected to the flap limiting member 53 and has a movement tendency of driving the flap limiting member 53 toward the first position; The fork tongue 57 is hinged to the flap body 52; The tongue guide block 58 abuts against the fork tongue 57 and / or the tongue body 52; The tongue-turning reset member 581 abuts against the tongue-turning guide block 58 and is used to drive the tongue-turning body 52 to extend out of the housing 1. The beneficial effects of the present invention are as follows: through the setting of the tongue-turning body, the tongue can rotate freely after unlocking the tongue limit member, which is convenient for opening and closing the door, saving time and effort, with simple operation. And through the locking limit of the tongue limit member, the tongue can achieve the door locking function, with simple structure, small opening force and wide adaptation range. The present invention also has the advantages of simple structure, convenient assembly, reliable action and long service life. When the tongue limit member is unlocked, compared with the bevel tongue, its opening force is smaller and the stroke is shorter, and it can be pushed open without operation, which is convenient for opening and closing the door casually, saving time and effort and having simple operation; when the tongue limit member is interlocked, it can achieve the effect of locking the door, simplifying the structure at the bevel tongue and tongue-turning of the existing electronic lock, reducing the number of parts and the difficulty of assembly and transmission.

[0037] The described tongue limit member 53 is hingedly arranged, and the tongue limit member 53 has a first position for limiting the flipping of the tongue-turning body 52 during installation and a second position for facilitating the free movement of the tongue after rotational unlocking. Specifically, there are two tongue limit members 53, and a tongue slot 521 is provided on the side surface of the tongue-turning body 52. The tongue limit member 53 is inserted into the tongue slot 521 to limit the flipping of the tongue-turning body 52. More specifically, the two different tongue limit members 53 cooperate with each other through a tongue limit groove 531 and a tongue limit driving block 532 to realize the linkage of different tongue limit members 53. Such a structure enables the tongue unlocking piece to conveniently drive the two tongue limit members to act when it moves, with convenient unlocking. When the tongue limit member limits the tongue-turning body, the tongue-turning body plays the role of a bevel tongue, that is, it can also play the role of locking the door; and when the tongue limit member is unlocked, it can be directly pushed to make the tongue-turning body flip. The setting of the tongue slot facilitates the action and locking of the tongue limit member, with simple structure, convenient and reliable interlocking. The tongue limit member is hinged and can be rotatably arranged, making the interlocking and unlocking of the tongue limit member convenient, with simple operation and being easily and reliably driven by the tongue unlocking piece.

[0038] The present invention further includes a tongue mounting plate 55, and both the tongue-turning body 52 and the tongue limit member 53 are arranged on the tongue mounting plate 55. Specifically, a tongue accommodating cavity 551 is provided on the tongue mounting plate 55. The tongue-turning body 52 is arranged in the tongue accommodating cavity 551 and sequentially passes through the tongue mounting plate 55 and the housing 1. The tongue limit member 53 is arranged in the tongue accommodating cavity 551 and is rotationally matched with the tongue mounting plate 55. The setting of the tongue mounting plate enables the overall replacement of the product, and the tongue structure can be assembled, disassembled and replaced integrally. The product assembly is simple and the adaptation range is wide.

[0039] The present invention further includes a tongue unlocking piece 56, which is arranged on the housing 1; the other end of the tongue limiting piece 53 relative to the tongue body 52 penetrates through the tongue mounting plate 55, and a tongue limiting driving groove 533 for facilitating the driving of the tongue unlocking piece 56 is arranged on the tongue limiting piece 53; the tongue unlocking piece 56 rotates to drive the tongue limiting piece 53 to rotate and unlock the tongue body 52. The arrangement of the tongue unlocking piece makes the unlocking of the tongue limiting piece convenient, with a simple structure and reliable transmission.

[0040] The present invention further includes a fork tongue 57, which is hinged to the tongue body 52; A tongue guiding block 58, which abuts against the fork tongue 57 and / or the tongue body 52; A tongue resetting piece 581, which abuts against the tongue guiding block 58 and is used to drive the tongue body 52 to extend out of the housing 1. Specifically, a tongue inclined surface 522 and an arc-shaped turning part 523 are arranged on the tongue body 52, and a fork tongue inclined surface 571 is arranged on the fork tongue 57. The horizontal height of the fork tongue inclined surface 571 is higher than the horizontal height of the tongue inclined surface 522. More specifically, a fork tongue limiting block 572 is arranged on the fork tongue 57. The fork tongue limiting block 572 and the fork tongue inclined surface 571 are arranged in an L shape. The fork tongue limiting block 572 is arranged inside the housing 1, and the fork tongue inclined surface 571 extends out of the housing 1. When closing the door, the fork tongue (fork tongue inclined surface) first touches the door frame, and at this time, the tongue limiting block is flipped so that the fork tongue and the tongue body retract (towards the inside of the housing). When the fork tongue inclined surface is adapted to the tongue inclined surface, they retract in place synchronously, and then are controlled by the tongue resetting piece to pop out of the housing to lock the door body. Generally, at this time, the tongue limiting piece is in the first position, the tongue body is limited, and the door cannot be opened when the tongue limiting piece is not unlocked; rotating the tongue unlocking piece makes the tongue limiting piece in the second position. At this time, the tongue limiting piece rotates and unlocks, and the tongue body can freely flip. At this time, when pushing the door, the tongue flips and the door opens.

[0041] The clutch assembly 62 includes: A clutch rotating shaft 621, which is connected to the gear assembly 63 and used to drive the gear assembly 63 to act; the clutch rotating shaft 621 includes an axially sliding part 6211 and a bevel gear part 6212 connected to the gear assembly 63; A clutch dial 622, which is connected to the power source 61 and driven to rotate by the power source 61; the clutch dial 622 is sleeved on the axially sliding part 6211 and is circumferentially and axially slidably matched with the clutch rotating shaft 621; A clutch dial piece 623, which is arranged on the housing 1.

Specifically, generally, a circuit board is provided inside the housing. The circuit board is connected to the power source and is used to control the operation of the power source. When the user activates it through instructions such as light, electricity, magnetism, sound, password, face recognition, and / or fingerprint recognition, the control circuit board drives the main lock tongue to retract and unlock through the power source, facilitating the user to open the door. Such a structure can reliably drive the clutch pulley to act through the clutch paddle, realizing the engagement and disengagement of the clutch assembly. In this way, when powered electrically, the gear assembly can reliably drive the transmission mechanism to act, thereby realizing the movement of the main lock tongue, achieving interlocking or unlocking. When unlocking manually or with a key, the rotation drives the clutch paddle to rotate, thereby realizing the separation of the clutch assembly. In this way, when unlocking manually or with a key, the gear assembly will not drive the power source to rotate in the reverse direction, avoiding damage to components and ensuring a long service life of the product.
