In conjunction with fig. 1-20, the present embodiment provides a lock mechanism 100 comprising:

a housing 10;

a knob 12, the knob 12 being rotatably connected to the housing 10, the knob 12 being configured to be connected to the lock body;

a locking structure 14, the locking structure 14 comprising a locking member 142, the locking member 142 being movably connected to the housing 10, the locking member 142 being configured to lock or unlock the knob 12;

the driving member 16, the driving member 16 is movably disposed in the housing 10, the driving member 16 is provided with a pushing portion 161 and a locking portion 162, the pushing portion 161 is configured to push the locking member 142 to move, so that the locking member 142 unlocks the knob 12, and the locking portion 162 is configured to lock or unlock the knob 12;

a lock cylinder 18, the lock cylinder 18 being rotatably connected to the housing 10 and configured to drive the driving member 16 to move;

the lock mechanism 100 has a first state in which the key cylinder 18 rotates by a first preset angle, the locking member 142 unlocks the knob 12, and the locking portion 162 locks the knob 12; and a second state in which the key cylinder 18 is rotated by a second preset angle, the locking member 142 keeps unlocking the knob 12, and the locking portion 162 unlocks the knob 12.

It should be noted that the lock mechanism 100 is generally installed on a structure requiring locking, such as a door, a cabinet, etc., and the locking structure 14, the driving member 16, and a reset member 20, which will be described below, and various elastic members, etc., are located inside the housing 10, and the housing 10 protects these structures.

The knob 12 protrudes from the outer surface of the housing 10, and the locking or unlocking of a lock body, which is a mechanism for actually locking a door or a cabinet, etc., can be realized by rotating the knob 12. The knob 12 can also be in the form of a handle, a handle and the like, the knob 12 can be directly connected with a mechanism for actually locking the door, or indirectly connected with a lock body through structures such as a gear, a clamping rod and the like, so that the opening and closing functions can be realized when the knob 12 is rotated.

The locking member 142 can lock or unlock the knob 12, and the connection between the locking member 142 and the housing 10 can be a sliding connection or a rotating connection, i.e. the locking or unlocking of the knob 12 can be achieved by sliding or rotating.

The driving member 16 can lock or unlock the knob 12 through the locking portion 162, and meanwhile, the driving member 16 can push the locking member 142 through the pushing portion 161 to unlock the knob 12 through the locking member 142.

When the key cylinder 18 is matched with the corresponding key 50, the key 50 is rotated, and the key cylinder 18 can drive the driving piece 16 to move, so that the locking part 162 can lock or unlock the knob 12. Such a key cylinder 18 is in the form of a conventional key cylinder, and in other embodiments, the key cylinder 18 may be in the form of another knob, or an unlocking tool or the like that moves the driving member 16.

Taking the lock mechanism 100 in fig. 1-5 as an example, after the key 50 fitted to the key cylinder 18 is inserted, the key 5090 may be rotated clockwise, the driving member 16 moves upward, the pushing portion 161 pushes the locking member 142 to move upward, the locking member 142 unlocks the knob 12, and the locking portion 162 of the driving member 16 locks the knob 12, at this time, the knob 12 cannot be rotated, that is, the lock body cannot be unlocked by rotating the knob 12.

At this time, the key 5090 ° can be rotated counterclockwise (or the key 5090 ° can be rotated clockwise) again, the driving member 16 moves downward, the pushing portion 161 moves downward, the locking member 142 maintains the unlocked state of the knob 12, the locking portion 162 moves downward to unlock the knob 12, and at this time, the knob 12 can be rotated to unlock the lock body.

The first predetermined angle is understood to mean a 90 ° clockwise rotation, and the second predetermined angle is understood to mean a 90 ° counterclockwise rotation, or a further 90 ° clockwise rotation (i.e. corresponding to a 180 ° clockwise rotation in the initial state).

In this embodiment, the locking structure 14 further includes a driver 141, and the driver 141 is connected to the housing 10 and configured to drive the locking member 142, so that the locking member 142 locks or unlocks the knob 12.

The driver 141 can adopt an electromagnetic driving mode, an electric driving mode and the like, the locking piece 142 is driven to lock or unlock the knob 12, a microcomputer can be arranged in the shell 10 and is communicated with the driver 141, and the driver 141 is remotely controlled by the mobile phone to lock or unlock the knob 12 by the remote control of the mobile phone in a mode of arranging an APP at the mobile phone end and communicating with the microcomputer in the shell 10; or by installing a detection switch, when the detection switch detects that the door or the cabinet needs to be locked, the microcomputer automatic control driver 141 locks the knob 12; or a card swiping sensing device is installed in the housing 10, and when the corresponding card approaches the sensing device, the microcomputer can control the driver 141 to correspondingly lock or unlock the knob 12 according to whether the card is an authorized card.

Generally, the lock mechanism 100 can be modified into an electronic lock by installing a driver 141, a microcomputer, a detection switch, a sensor, or the like. The modification mode can be directly realized by adopting a mature technical scheme in the electronic lock in the prior art, and is not described herein any more.

Referring to fig. 2 to 5, in the present embodiment, the locking member 142 is slidably connected to the housing 10, and the driver 141 includes an electromagnetic mechanism configured to drive the locking member 142 to slide, so that the locking member 142 locks or unlocks the knob 12.

The locking member 142 is in the shape of a rod, which may be magnetic or be a magnet as a whole, and the electromagnetic mechanism can move the locking member 142 in a forward direction by applying a forward current and move the locking member 142 in a reverse direction by applying a reverse current. In this way, the extension or retraction of the locking member 142 can be achieved by changing the direction of the current, locking the knob 12 when the locking member 142 is extended with respect to the electromagnetic mechanism, and unlocking the knob 12 when the locking member 142 is retracted with respect to the electromagnetic mechanism. (alternatively, the locking member 142 may be extended to unlock the knob 12, and the locking member 142 may be retracted to lock the knob 12.)

In one implementation, the locking member 142 is not magnetic and has a permanent magnet attached to its end. Optionally, a permanent magnet is also mounted within the electromagnetic mechanism, which may also attract the locking member 142 after the electromagnetic mechanism is de-energized.

Generally, when the lock mechanism 100 is in the second state, the solenoid mechanism may be energized in a reverse direction such that the locking member 142 remains retracted and the locking member 142 is prevented from falling to lock the knob 12. Of course, it is also possible that the locking member 142 has a significant frictional effect with the housing 10 such that the locking member 142 cannot move downwardly under the influence of gravity, or that the locking mechanism 100 of fig. 2 is inverted, in the second state the locking member 142 remaining in the retracted state. Or a permanent magnet at the end may attract a ferrous frame outside the electromagnetic mechanism to maintain the locking member 142 in the retracted state.

With reference to fig. 2 to 5, in the present embodiment, the lock mechanism 100 further includes a reset element 20, the reset element 20 is movably connected to the housing 10, the reset element 20 is provided with a driving portion 201 and a driving portion 202, and the knob 12 is configured to drive the driving portion 201 to move, so that the driving portion 202 drives the locking element 142 to move, and the locking element 142 locks the knob 12.

The existence of the reset piece 20, when the lock body is required to be locked after the lock body is unlocked, the knob 12 can be rotated, the knob 12 drives the driving portion 201 to move, so that the driving portion 202 drives the locking piece 142 to lock the knob 12 again.

In this embodiment, the lock mechanism 100 further includes a first elastic member 26, two elastic ends of the first elastic member 26 are respectively connected to the reset member 20 and the housing 10, and the first elastic member 26 makes the driving portion 202 have a movement tendency to disengage from the locking member 142.

The first elastic element 26 is a spring, and the existence of the first elastic element 26 enables the driving part 202 to be separated from the locking element 142 under the action of the first elastic element 26 of the reset element 20 when the knob 12 no longer generates driving force for the reset element 20 and the movement of the reset element 20 is not limited, the driving part 202 no longer generates driving force for the locking element 142, and the locking element 142 can perform normal action.

Referring to fig. 6-10, in the present embodiment, a driving groove 121 is formed on an outer wall of the knob 12, and the driving portion 201 is located in the driving groove 121, so that when the knob 12 rotates, the knob 12 drives the reset element 20 to move.

When the knob 12 rotates, the wall of the driving groove 121 will abut against the driving portion 201, so that the driving portion 201 is driven to displace, and the reset element 20 is thereby displaced. In this manner, rotation of the knob 12 is translated into translation of the reset member 20.

Or a protrusion may be disposed on an outer wall of the knob 12, and in a process of rotating the knob 12, the protrusion drives the reset member 20 to move, which is similar to a cam mechanism, and converts rotation of the knob 12 into translation of the reset member 20.

Referring to fig. 3 to fig. 5, in the embodiment, the outer wall of the knob 12 is provided with a first receiving groove 122, the reset element 20 is slidably connected to the housing 10, a sliding direction of the reset element 20 relative to the housing 10 is a first sliding direction, the driving portion 201 has a first contact surface 203 inclined to the first sliding direction, and the first contact surface 203 contacts with a groove wall of the first receiving groove 122, so that when the knob 12 rotates, the groove wall of the first receiving groove 122 pushes the driving portion 201 to move, and the reset element 20 slides relative to the housing 10.

Referring to the relative positions shown in fig. 3-5, the first receiving groove 122 is disposed on the bottom wall of the knob 12, the driving portion 201 can extend into the first receiving groove 122, and when the knob 12 rotates, the groove wall of the first receiving groove 122 can push the driving portion 201 to move, so as to move the reset element 20. In this way, it is possible to convert the rotation of the knob 12 into a translation of the return element 20.

Referring to the relative positions shown in fig. 3-5, in this embodiment, the outer wall of the knob 12 is further provided with a second receiving groove 123, the driving member 16 is slidably connected to the housing 10, the lock cylinder 18 is connected to the cam 28, and the cam 28 contacts with the driving member 16 and forms a cam mechanism, so that when the lock cylinder 18 rotates, the cam 28 can push the driving member 16, so that the locking portion 162 is clamped in the second receiving groove 123 to lock the knob 12.

The second receiving groove 123 is formed in the bottom wall of the knob 12, and may be communicated with the first receiving groove 122, or it may be understood that the first receiving groove 122 and the second receiving groove 123 are the same groove, and by means of the cam mechanism, the rotation of the lock cylinder 18 may be converted into the translational movement of the driving member 16, and the locking portion 162 of the driving member 16 may be moved upward and may be clamped into the second receiving groove 123, and may be moved downward and may be disengaged from the second receiving groove 123.

In this embodiment, the rotation axis of the cam 28 is perpendicular to the sliding direction of the driving member 16, and the cam mechanism can realize rotation and translation. Of course, there are many ways to realize the rotation and translation, and when the position of the lock core 18 is changed, the rotation and translation can be realized by adopting a crank slide block, a crank rocker, a transmission rod and the like.

In this embodiment, the lock mechanism 100 further includes a second elastic member 30, two elastic ends of the second elastic member 30 are respectively connected to the housing 10 and the driving member 16, and the second elastic member 30 makes the locking portion 162 have a movement tendency of being caught in or withdrawn from the second receiving groove 123.
