In order to make the technical solution better understood by those skilled in the art, the technical solution in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It should be apparent that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.

Referring to fig. 1, a lock 100 according to an embodiment of the present disclosure mainly includes a housing 10, a flip-latch assembly 21, a main latch assembly 22, a driving gear 30, a locking block 41, and an unlocking lever 42. The housing 10 may be mounted within a door and is used to carry a flip-latch assembly 21, a main latch bolt assembly 22, a drive gear 30, and a dial 50. The flip-tongue assembly 21 and the main bolt assembly 22 cooperate to lock the door to improve the security of the lock 100. When the lock 100 is in the locked state, the flip-latch assembly 21 and the main latch assembly 22 both extend out of the housing 10; when the lock 100 is in the unlocked state, the main latch bolt assembly 22 is accommodated in the housing 10, and the flip-latch bolt assembly 21 can be accommodated in the housing 10 when a user performs a door opening operation. The drive gear 30 is used to provide a driving force for retracting the flip bolt assembly 21 and the main latch bolt assembly 22 into the housing 10. The unlocking rod 42 is used for driving the locking block 41 to be selectively connected with or disconnected from the turnover tongue assembly 21, and when the locking block 41 is connected with the turnover tongue assembly 21, the locking block 41 limits the rotation of the turnover tongue assembly 21.

With reference to fig. 1, the housing 10 may include a bottom case 11 and a guiding plate 12, the bottom case 11 is configured to be installed in the door, the guiding plate 12 may be disposed on an edge of the bottom case 11 and enclose the bottom case 11 to form an accommodating cavity 13, the guiding plate 12 is provided with a first locking hole 122 and a second locking hole 123, and the first locking hole 122 and the second locking hole 123 are disposed at an interval.

The driving gear 30 is rotatably disposed at the bottom case 11 and may be located between the flip tongue assembly 21 and the main tongue assembly 22, and the driving gear 30 is used for receiving external power. Illustratively, a driving motor (not shown in the figures) may be disposed in the accommodating cavity 13, and the driving motor is in transmission connection with the driving gear 30 to drive the driving gear 30 to rotate, so as to provide a driving force; alternatively, the driving gear 30 may be provided coaxially with the door handle and rotated in synchronization, and when the user rotates the door handle, the driving gear 30 is rotated in synchronization with the door handle, thereby providing the driving force. Of course, the driving gear 30 may also have other ways of receiving external power or energy source power, and is not limited herein.

The main bolt assembly 22 is telescopically arranged along the axial direction of the second lock hole 123. In some embodiments, one end of the dial 50 is disposed coaxially with the driving gear 30 and is drivingly connected to the driving gear 30 such that rotation of the driving gear 30 causes the dial 50 to rotate synchronously and the other end is drivingly connected to the main bolt assembly 22. When the driving gear 30 drives the shifting block 50 to rotate synchronously, the shifting block 50 drives the main bolt assembly 22 to move telescopically.

In other embodiments, one end of the main lock tongue assembly 22 away from the second lock hole 123 may be provided with a tooth portion extending along the axial direction of the second lock hole 123, and the tooth portion may be engaged with the driving gear 30, so that the driving gear 30 rotates to drive the tooth portion to move along the axial direction of the second lock hole 123, thereby driving the main lock tongue assembly 22 to move.

Referring to fig. 2, in some embodiments, the lock 100 further includes a clutch device 60, the clutch device 60 is disposed between the dial 50 and the driving gear 30, and the clutch device 60 is used for selectively connecting or disconnecting the dial 50 and the driving gear 30. When the shifting block 50 is connected with the driving gear 30, the shifting block 50 and the driving gear 30 synchronously rotate; when the dial 50 is disengaged from the drive gear 30, the drive gear 30 rotates and the dial 50 is stationary.

In other embodiments, the dial 50 is fixedly coupled to the drive gear 30 such that the dial 50 rotates continuously in synchronization with the drive gear 30.

For example, the clutch device 60 may include a first sliding chute 61 and a first sliding block 62. The first sliding groove 61 is disposed on the surface of the shifting block 50 facing the driving gear 30, the first sliding groove 61 is an arc-shaped groove and extends around the rotation axis of the shifting block 50, and two ends of the first sliding groove 61 are not communicated. The first sliding block 62 is disposed on a surface of the driving gear 30 facing the shifting block 50 and slidably embedded in the first sliding groove 61, and when the first sliding block 62 moves in the first sliding groove 61, the driving gear 30 is separated from the shifting block 50, and when the first sliding block 62 abuts against side walls of the first sliding groove 61 located at two ends, the driving gear 30 is connected with the shifting block 50, and the driving gear 30 can drive the shifting block 50 to rotate.

Referring to fig. 1 again, the tongue-flipping component 21 may include a tongue body 211, a connecting column 212, and a reset seat 213.

The connecting column 212 is arranged in a telescopic manner along the axial direction of the first locking hole 122, the tongue body 211 is hinged to one end of the connecting column 212 close to the guide plate 12, and the tongue body 211 can selectively extend out of the first locking hole 122 or be accommodated in the accommodating cavity 13. When the door is in a closed state, the tongue 211 extends out of the first locking hole 122 and into the locking groove in the door frame, and abuts against the inner wall of the locking groove. It should be noted that, in the present embodiment, the tongue 211 can rotate around an axis parallel to the guide plate 12 and the bottom case 11, so as to realize the bidirectional opening or closing of the door. When the door is in a closed state but can be opened (that is, the door is in a closed state but the tongue body 211 is in an unlocked state), that is, the tongue body 211 is in a state of protruding out of the first lock hole 122 but can be accommodated in the accommodating cavity 13, at this time, when the user rotates the door forward or reversely, the tongue body 211 abuts against the side wall of the lock groove, and the side wall of the lock groove exerts a force on the tongue body 211, so that the tongue body 211 is accommodated in the accommodating cavity 13, thereby realizing the door opening action.

In some embodiments, the reset push seat 213 may be slidably disposed on the bottom housing 11 along an axial direction of the first locking hole 122, and may be slidable to a first limit position closest to the first locking hole 122 and to a second limit position farthest from the first locking hole 122, and the reset push seat 213 may selectively abut against or separate from the tongue body 211. Specifically, when the reset push seat 213 moves to the first limit position, the reset push seat 213 abuts against the tongue body 211 and applies a force to the tongue body 211 to extend out of the first lock hole 122, so that the tongue body 211 can stably extend out of the first lock hole 122; when the reset push seat 213 moves to the second limit position, the reset push seat 213 is separated from the tongue body 211, the tongue body 211 is in an unstressed state, and at this time, the user can rotate the door, and the tongue body 211 is accommodated in the accommodating cavity 13 under the action of the force applied by the side wall of the lock slot, so that the door opening action is realized.

In other embodiments, the reset push seat 213 may be connected to the tongue body 211, and the reset push seat 213 drives the tongue body 211 to extend out of the first locking hole 122 or to be accommodated in the accommodating cavity 13.

In some embodiments, one end of the reset push seat 213 away from the first locking hole 122 is provided with a rack 214, and the driving gear 30 is in transmission connection with the rack 214, so that the driving force provided by the driving gear 30 is transmitted to the rack 214, thereby moving the reset push seat 213.

In other embodiments, a driving member similar to the dial 50 may be disposed on the driving gear 30, and an end of the driving member away from the driving gear 30 is connected to an end of the reset push seat 213 away from the first lock hole 122, so as to drive the reset push seat 213 to reciprocate.

Referring to fig. 2 again, in order to enable the driving gear 30 to drive the flip-flop bolt assembly 21 and the main bolt assembly 22 to be accommodated in the accommodating cavity 13 when rotating, in this embodiment, the lock 100 further includes a first transmission gear 71 and a second transmission gear 72, the first transmission gear 71 is externally engaged with the driving gear 30, the second transmission gear 72 is coaxially disposed with the first transmission gear 71 and is engaged with the rack 214, and the first transmission gear 71 can drive the second transmission gear 72 to rotate in the same direction when rotating. When the driving gear 30 rotates and drives the main bolt assembly 22 to retract into the accommodating cavity 13, the driving gear 30 drives the first transmission gear 71 to rotate, and the direction of rotation of the first transmission gear 71 is opposite to the direction of rotation of the driving gear 30. When the first transmission gear 71 rotates, the second transmission gear 72 can be driven to rotate synchronously and in the same direction, that is, the rotation direction of the second transmission gear 72 is opposite to the rotation direction of the driving gear 30, and the second transmission gear 72 drives the rack 214 to move towards the direction away from the first lock hole 122, so as to drive the reset push seat 213 to move. It can be understood that, when the driving gear 30 disposed between the flip tongue assembly 21 and the main tongue assembly 22 rotates in a specific direction, the flip tongue assembly 21 and the main tongue assembly 22 can be simultaneously driven to be accommodated in the accommodating cavity 13 in the same direction, so as to implement the prerequisite condition that the door opening action can be performed.

The first transmission gear 71 and the second transmission gear 72 can be selectively connected or disconnected. Specifically, a second sliding slot 721 can be arranged on the surface of the second transmission gear 72 facing the first transmission gear 71, the second sliding slot 721 is an arc-shaped slot and can extend around the rotation axis of the second transmission gear 72, and the head end and the tail end of the second sliding slot 721 are not communicated; a second slider 711 may be provided on a surface of the first transmission gear 71 facing the second transmission gear 72, the second slider 711 being slidably inserted into the second sliding slot 721. When the second sliding block 711 moves in the second sliding slot 721, the first transmission gear 71 is separated from the second transmission gear 72, and when the first transmission gear 71 rotates, the second transmission gear 72 is stationary; when the second sliding block 711 abuts against the side wall at the head end or the tail end of the second sliding slot 721, the first transmission gear 71 is connected with the second transmission gear 72, and at this time, the first transmission gear 71 can drive the second transmission gear 72 to rotate in the same direction when rotating.

The locking block 41 can be selectively located at a first position and a second position, when the locking block is located at the first position, the locking block limits the rotation of the tongue body 211 relative to the connecting column 212 or relative to the guide plate 12, so as to lock the tongue body 211; when the locking member is located at the second position, the locking member is disengaged from the tongue body 211 to unlock the tongue body 211, and at this time, the tongue body 211 can rotate relative to the connecting post 212.

In order to realize that when the driving gear 30 drives the main latch bolt assembly 22 to move, the locking block 41 can be driven to switch from the first position to the second position, so as to unlock the bolt body 211, the unlocking lever 42 can be rotatably disposed on the bottom case 11, and the unlocking lever 42 has a first lever arm 421 and a second lever arm 422, the first lever arm 421 is in transmission connection with the locking block 41, the second lever arm 422 is in transmission connection with the driving gear 30, and when the driving gear 30 rotates, the second lever arm 422 is driven to rotate around the rotation axis of the unlocking lever 42 in the first rotation direction, so that the first lever arm 421 rotates around the rotation axis of the unlocking lever 42 in the first rotation direction, and further the locking block 41 is driven to switch from the first position to the second position.

In some embodiments, the lock 100 may further include a third transmission gear 73, and the third transmission gear 73 may be disposed on a side of the driving gear 30 away from the flip tongue assembly 21 and engaged with the driving gear 30. The second lever arm 422 is connected to the third transmission gear 73, and when the driving gear 30 rotates and drives the third transmission gear 73 to rotate in the forward direction, the third transmission gear 73 drives the first lever arm 421 to rotate around the rotation axis of the unlocking lever 42 in the first rotation direction through the second lever arm 422, so as to drive the locking block 41 to switch from the first position to the second position. The first rotational direction may be the same as the direction in which the third transmission gear 73 rotates in the forward direction, for example, both clockwise directions.

In other embodiments, the second lever arm 422 may be coupled to the drive gear 30.

Since the tongue 211 is greatly acted by the force applied by the side wall of the door frame at the locking groove, the power required to switch the locking block 41 from the first position to the second position is also large. In order to solve the problem that the power required by the locking block 41 is large, the length of the force arm of the second lever arm 422 may be greater than that of the first lever arm 421, and when the third transmission gear 73 applies a force to the second lever arm 422 and drives the first lever arm 421 to rotate around the rotation axis of the unlocking lever 42 in the first rotation direction, the first lever arm 421 applies a force to the locking block 41 to drive the locking block 41 to be switched from the first position to the second position. It can be understood that, a distance between the force application point of the second lever arm 422 under the action of the force applied by the third transmission gear 73 and the rotation axis of the unlocking lever 42 is a moment arm length of the second lever arm 422, and a distance between the force application point of the first lever arm 421 on the locking block 41 and the rotation axis of the unlocking lever 42 is a moment arm length of the first lever arm 421, and since the moment of the first lever arm 421 is the same as the moment of the second lever arm 422 and the moment arm length of the second lever arm 422 is greater than the moment arm length of the first lever arm 421, it can be known that the force applied by the first lever arm 421 on the locking block 41 is greater than the force applied by the third transmission gear 73 on the second lever arm 422, so that the driving force of the driving gear 30 can be transmitted to the locking block 41 after being amplified by the unlocking lever 42.

In order to further enhance the acting force of the first lever arm 421 on the locking block 41, in some embodiments, the number of teeth of the first transmission gear 71 and the number of teeth of the second transmission gear 72 may be both smaller than the number of teeth of the third transmission gear 73, so that the angular speed of the third transmission gear 73 when rotating is smaller than the angular speeds of the first transmission gear 71 and the second transmission gear 72 when rotating, and further, the acting force of the third transmission gear 73 on the second lever arm 422 is increased, thereby achieving the purpose of enhancing the acting force of the first lever arm 421 on the locking block 41.

In other embodiments, the number of teeth of the first transmission gear 71, the number of teeth of the second transmission gear 72 and the number of teeth of the third transmission gear 73 are the same and more.

In some embodiments, the lock 100 further includes a restoring member, which is connected to the unlocking lever 42 and the bottom case 11, and applies a restoring force to the unlocking lever 42, wherein the restoring force rotates in a second rotation direction (opposite to the first rotation direction), when the driving gear 30 drives the third transmission gear 73 to rotate in the opposite direction, the unlocking lever 42 rotates around the rotation axis in the second rotation direction and restores, and at this time, the first lever arm 421 drives the locking block 41 to switch from the second position to the first position, so that the locking block 41 locks the tongue 211.

In other embodiments, third drive gear 73 rotates in the opposite direction to rotate lock release lever 42 in the second rotational direction instead of the return member.

The working principle of the lockset 100 provided by the embodiment of the application is as follows:

fig. 3 shows the unlocking action: the driving gear 30 rotates, the first sliding block 62 abuts against the side wall of one end of the first sliding groove 61 and drives the shifting block 50 to rotate, and the main bolt assembly 22 is pulled by the shifting block 50 to retreat into the lock body; the driving gear 30 drives the third transmission gear 73 to rotate in the forward direction so as to drive the unlocking rod 42 to rotate in the first rotation direction, and the unlocking rod 42 drives the locking block 41 to be switched from the first position to the second position, so that the tongue body 211 of the turnover tongue assembly 21 is unlocked; when the driving gear 30 rotates, the second transmission gear 72 is driven to rotate, the second slider 711 abuts against the side wall at one end of the second sliding chute 721 and drives the third transmission gear 73 to rotate, the third transmission gear 73 drives the reset push seat 213 to move towards the direction far away from the first lock hole 122, so that the reset push seat 213 is separated from the tongue body 211, the tongue body 211 is in an unstressed state, and the tongue body 211 can rotate relative to the guide plate 12 and can also stretch and retract along the first lock hole 122; when the user pushes the door, the side wall of the locking groove of the door frame contacts the tongue body 211 to apply force to the tongue body 211, so that the tongue body 211 is rotated and retracted into the receiving cavity 13.

Fig. 4 shows the unlocking reset action: referring to fig. 4, the driving gear 30 is reset, the first sliding block 62 moves in the first sliding groove 61 toward the side wall of the other end of the first sliding groove 61, and the driving gear 30 is reset to a position where the first sliding block 62 contacts the side wall of the other end of the first sliding groove 61, in which process the dial block 50 is stationary; the tongue body 211 is kept in a state of being extended out of the first lock hole 122; the driving gear 30 drives the third transmission gear 73 to reset, the third transmission gear 73 releases the acting force on the unlocking rod 42, so that the unlocking rod 42 can rotate in the second rotation direction under the action of the restoring piece and reset, and drives the locking block 41 to be switched from the second position to the first position so as to lock the tongue body 211, namely limit the tongue body 211 to rotate; after the acting force on the tongue body 211 disappears, the reset push seat 213 can drive the tongue body 211 to move toward the direction close to the first locking hole 122, so that the tongue body 211 extends out of the first locking hole 122. In the state after the unlocking reset, if the tongue body 211 is subjected to the axial force and retracts into the accommodating cavity 13, the tongue body 211 pushes the reset push seat 213 to move towards the direction away from the first lock hole 122, and the second slider 711 can move in the second sliding slot 721 towards the side wall at the other end of the second sliding slot 721, so that the second transmission gear 72 cannot drive the first transmission gear 71 to rotate, the reverse driving power device cannot be generated, and the service life of the driving gear 30 is prolonged.

Fig. 5 shows the locking action: the driving gear 30 rotates reversely, the first sliding block 62 abuts against the side wall of the other end of the first sliding groove 61 and drives the shifting block 50 to rotate reversely, and the shifting block 50 drives the main bolt assembly 22 to extend out of the second lock hole 123; the driving gear 30 rotates the third transmission gear 73 in the reverse direction.

Fig. 6 shows the lock reset action: the driving gear 30 is reset, the driving gear 30 is reset to a position where the first slider 62 contacts with the side wall of one end of the first sliding chute 61, and the dial 50 is stationary in the above process.
