Example 1:

[0022] Reference Figure 1-5 An electronic lock that locks quickly includes an inner panel assembly 1 and an outer panel assembly 2. The inner panel assembly 1 includes an inner panel 11, an inner shaft 12, an inner handle 13, and an inner cover 14. One end of the inner shaft 12 is connected to the inner handle 13 outside the inner panel 11, and the other end is rotatably installed inside the inner panel 11. An inner slot 121 is provided on the other end of the inner shaft 12. The lock is characterized in that: a locking member 3, an electric clutch assembly 4, and a manual clutch assembly are provided inside the inner panel 11. The locking member 3 is slidably guided inside the inner panel 11, and a locking insertion part 30 for engaging with the inner slot 121 is provided on the locking member 3. Furthermore, the electric clutch assembly 4 is connected in cooperation with the locking member 3, and the electric clutch assembly 4 is configured to drive the locking member 3 to move to unlock, thereby realizing the electric unlocking function.

[0023] Furthermore, the manual clutch assembly includes a manual unlocking component 5 and a linkage component 6. The inner panel 11 is provided with an operation hole 110 for exposing the manual unlocking component 5, so that the user can operate the manual clutch assembly to unlock. One end of the linkage component 6 is connected to the manual unlocking component 5, and the other end is indirectly connected to the locking component 3. The manual unlocking component 5 is configured to drive the locking component 3 through the linkage component 6 to unlock, thereby realizing the manual unlocking function.

[0024] Furthermore, the inner cover plate 14 is bolted to one end of the inner panel 11 facing away from the inner handle 13. The inner cover plate 14 is used to confine the inner shaft 12, locking member 3, electric clutch assembly 4 and manual clutch assembly within the inner panel 11.

[0025] In this embodiment, when the other end of the linkage 6 indirectly engages with the locking member 3, transmission is achieved through the clutch push frame 41a. Specifically, the electric clutch assembly 4 includes a clutch housing 81, a clutch shaft rotatably installed inside the clutch housing 81, a first motor fixedly installed inside the clutch housing 81 and connected to drive the clutch shaft to rotate, and a clutch push frame 41a sliding inside the clutch housing 81 and sleeved outside the clutch shaft. One end of the clutch shaft is connected to the output shaft of the first motor through gear meshing. A clutch spring sleeved outside the clutch shaft is fixed on the clutch push frame 41a. A spring is used in the clutch mechanism. A pin is fixed on the clutch shaft, located between the clutch spring gaps. When the clutch shaft rotates, the pin pushes the clutch spring, causing the clutch pusher 41a to extend and retract. One end of the clutch pusher 41a is connected to the locking member 3 and the linkage member 6 outside the clutch housing 81, thereby enabling the locking member 3 to move and achieve the unlocking action. In addition, when unlocking using the manual clutch assembly, the clutch pusher 41a can be driven by the linkage member 6 and move in the unlocking direction by compressing the clutch spring, so that the linkage member 6 can perform the unlocking action through the clutch pusher 41a and the locking member 3. The structural principle of the electric clutch assembly 4 is based on existing conventional technology, and specific details can be found in the technical solution of application number CN202320532377.6.

[0026] In this embodiment, the locking member 3 is provided with a locking linkage port 31a, and the clutch push frame 41a is provided with a clutch drive protrusion 411a that cooperates with the locking linkage port 31a for transmission. The clutch drive protrusion 411a is inserted into the locking linkage port 31a so that the clutch push frame 41a can drive the locking member 3 to move.

[0027] In this embodiment, the inner panel 11 is provided with a telescopic slide groove 111 for guiding the locking member 3. At least part of the locking member 3 is guided and installed in the telescopic slide groove 111 to ensure the stability of the locking member 3 during movement, avoid deviation or jamming, and allow the locking insert 30 to stably enter and exit the inner slot 121 to achieve locking or unlocking.

[0028] In this embodiment, the manual unlocking component 5 is a toggle shaft, the operating hole 110 is an operating shaft hole, the toggle shaft is rotatably installed in the operating shaft hole, one end of the toggle shaft is fitted with a toggle handle 7 located outside the inner panel 11, and the other end is provided with a rotating toggle part 51a. The linkage component 6 is provided with a first linkage part 61a and a second linkage part 62a, wherein the first linkage part 61a overlaps and engages with the rotating toggle part 51a, and the second linkage part 62a is connected to one end of the clutch push frame 41a. Specifically, the linkage component 6, the first linkage part 61a and the second linkage part 62a form a "[" shaped linkage groove, the clutch push frame 41a and the rotating toggle part 51a both extend into the "[" shaped linkage groove, and the clutch push frame 41a and the rotating toggle part 51a respectively engage with the first linkage part 61a and the second linkage part 62a.

[0029] When the toggle handle 7 is manually rotated in the unlocking direction, the rotating toggle part 51a drives the first linkage part 61a to move, and the second linkage part 62a moves accordingly and acts on the clutch pusher 41a, so that the clutch pusher 41a can simultaneously drive the locking member 3 to move in the unlocking direction, thereby allowing the locking insert 30 to exit the inner slot 121 and realize the manual unlocking function. When the toggle handle 7 is manually rotated in the locking direction, the rotating toggle part 51a returns to its original position, but does not drive the first linkage part 61a to move. At this time, the clutch pusher 41a returns to its initial position under the reset action of the clutch spring, and simultaneously drives the linkage 6 and the locking member 3 to move in the locking direction, so that the linkage 6 returns to its original position, so as to facilitate the next manual unlocking operation; while the locking insert 30 is reinserted into the inner slot 121 to complete the locking action.

[0030] In this embodiment, the outer panel assembly 2 includes an outer panel 21, an outer rotating shaft 22, an outer handle 23, and an outer cover plate 24. One end of the outer rotating shaft 22 is connected to the outer handle 23 outside the outer panel 21, and the other end is rotatably installed inside the outer panel 21. Both the outer rotating shaft 22 and the inner shaft 12 are provided with square transmission holes, which are used to cooperate with the square shaft, thereby realizing the linkage between the inner shaft 12 and the outer rotating shaft 22, so that the inner handle 13 and the outer handle 23 can rotate synchronously. The outer cover plate 24 is installed on the end of the outer panel 21 facing away from the outer handle 23 by bolt connection, and the outer cover plate 24 is used to restrict the outer shaft inside the outer panel 21.

[0031] In this embodiment, the outer panel 21 is provided with a lock cylinder mounting hole 211 and a lock cylinder exposure hole 212. At least part of the lock cylinder of the smart lock is installed in the lock cylinder mounting hole 211, and the keyhole of the lock cylinder corresponds to the lock cylinder exposure hole 212. The outer panel 21 is provided with a control assembly 8 for controlling the operation of the first motor. The control assembly 8 is connected to the first motor through wiring. The housing 81 of the control assembly 8 is rotatably mounted on the outer panel 21. Under normal conditions, the control assembly 8 covers the lock cylinder exposure hole 212. In an emergency, the control assembly 8 is rotated to expose the lock cylinder exposure hole 212 so that the key can be inserted for emergency unlocking. The control assembly 8 is existing conventional technology and therefore will not be described in detail.

[0032] In this embodiment, the actuating shaft is provided with a key unlocking hole 50, which is used for the insertion of the transmission flat rod of the lock cylinder. By rotating the lock cylinder with the key, the transmission flat rod is driven to rotate, thereby driving the actuating shaft to rotate in the unlocking direction, thus realizing the key unlocking function. Example 2:

[0033] Reference Figure 6-10 This embodiment is basically the same as the structure of embodiment 1, except that: in this embodiment, the other end of the linkage 6 is directly engaged with the locking member 3. Specifically, the locking member 3 is provided with a first engaging part 31b, and the other end of the linkage 6 is provided with an operation linkage part 61b. The operation linkage part 61b is engaged and connected with the first engaging part 31b. Specifically, the operation linkage part 61b is hooked on the first engaging part 31b, so that when the manual unlocking member 5 is operated, it can drive the locking member 3 to move through the linkage 6 to realize the manual unlocking function.

[0034] In this embodiment, the manual unlocking component 5 is a push block, which slides and guides within a linear groove in the inner panel 11. One end of the linkage component 6 is fixedly connected to the push block. The push block has a linear actuating part 51b extending out from the operating hole 110. The user pushes the push block to slide within the inner panel 11 via the linear actuating part 51b, thereby moving the linkage component 6. This causes the other end of the linkage component 6 to act on the first mating part 31b of the locking component 3, thus achieving the manual unlocking function. Furthermore, the operating hole 110 is a rectangular opening communicating with the linear groove, and the linear actuating part 51b is a rectangular slider. The rectangular slider slides within the rectangular opening, and the extension direction of the rectangular opening is the same as the movement direction of the push block, thereby further improving the stability of the push block.

[0035] In this embodiment, the locking member 3 is provided with a second mating part 32b, and the electric clutch assembly 4 includes a second motor 41b installed in the inner panel 11 and a rotating push head 42b provided on the output shaft of the second motor 41b. The rotating push head 42b is provided with an unlocking drive protrusion 421b and a locking drive protrusion 422b for pushing against the second mating part 32b. The minimum distance between the unlocking drive protrusion 421b and the locking drive protrusion 422b is greater than the width of the second mating part 32b, thereby allowing the unlocking drive to... A reserved rotation gap is left between the movable protrusion 421b and the locking drive protrusion 422b to avoid jamming. The second mating part 32b is inserted between the unlocking drive protrusion 421b and the locking drive protrusion 422b. When the second motor 41b starts, when the output shaft of the second motor 41b rotates at a preset unlocking rotation angle in the first direction, the rotating push head 42b rotates and pushes against one side of the second mating part 32b through the unlocking drive protrusion 421b, thereby pushing the locking member 3 to move in a straight line in the unlocking direction, realizing the electric unlocking function. When the output shaft of the second motor 41b rotates at a preset locking rotation angle in the second direction, the rotating push head 42b pushes against the other side of the second mating part 32b through the locking drive protrusion 422b, driving the locking member 3 to move in a straight line in the locking direction, realizing the electric locking function, thereby completing the entire cycle of electric unlocking and locking.

[0036] In this embodiment, a key unlocking component 9 is rotatably installed inside the inner panel 11. The inner panel 11 has a rotating mounting cavity for installing the key unlocking component 9. The key unlocking hole 50 is provided on the key unlocking component 9. The key unlocking component 9 is provided with a key unlocking arm 91. The locking component 3 is provided with an unlocking mating groove 33b for cooperating with the key unlocking arm 91. When the key drives the transmission flat rod of the lock cylinder to rotate, it drives the key unlocking component 9 to rotate synchronously, causing the key unlocking arm 91 to swing and push against the groove wall of the unlocking mating groove 33b, thereby linking the locking component 3 to move in the unlocking direction to realize the key unlocking function.

[0037] In this embodiment, the control assembly 8, the outer panel assembly 2, and the inner panel assembly 1 are independently configured. The circuit portion of the control assembly 8 is connected to the second motor 41b via wiring. This independent configuration allows for a smaller size of the outer panel assembly 2 and the inner panel assembly 1, facilitating installation in different locations and improving installation flexibility and adaptability to meet the needs of various scenarios. The outer panel 21 has a decorative cover 26 for concealing the lock cylinder protrusion hole 212, which is detachably inserted into a decorative groove on the outer panel 21.

[0038] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
