[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] In addition, in the present utility model, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0038] Reference Figures 1 to 6 The utility model discloses an electronic lock 100, which is applied to a door, a cabinet or other structures that need to be locked.

[0039] The electronic lock 100 comprises a housing 1, a first locking tongue assembly 2, a second locking tongue assembly 3, a clutch mechanism 4, a driving mechanism 5 and a reset mechanism 6. The first locking tongue assembly 2, the second locking tongue assembly 3, the clutch mechanism 4, the driving mechanism 5 and the reset mechanism 6 are all arranged in the housing 1, and the first locking tongue assembly 2 and the second locking tongue assembly 3 are both linked with the clutch mechanism 4.

[0040] The clutch mechanism 4 has an engaged state and a disengaged state. In the engaged state, the clutch mechanism 4 can drive the first lock tongue assembly 2 and the second lock tongue assembly 3 to unlock under the action of an external force; in the disengaged state, the clutch mechanism 4 cannot drive the first lock tongue assembly 2 and the second lock tongue assembly 3 to unlock; the driving mechanism 5 is used to drive the clutch mechanism 4 to switch between the engaged state and the disengaged state. The clutch mechanism 4 also has an unlocking position and a locking position, and the reset mechanism 6 is used to provide a restoring force when the clutch mechanism 4 switches from the unlocking position to the locking position.

[0041] Based on the above-mentioned scheme, the reset mechanism 6 provides a restoring force for the clutch mechanism 4, so that when the clutch mechanism 4 is reset to the initial position, it is not affected by the drooping of the inner and outer handles, so that it can always remain in the initial position, thereby ensuring that the clutch mechanism 4 and the drive mechanism 5 remain within the effective alignment range, so as to effectively prevent the clutch mechanism 4 from being offset, so that the drive mechanism 5 can smoothly shift up or down the clutch mechanism 4, improve the switching smoothness of the clutch mechanism 4 between the engaged state and the disengaged state, and effectively prevent the clutch mechanism 4 from having a smooth gear shift or failure, so as to ensure the normal use of the clutch mechanism 4, thereby ensuring the normal opening and closing of the electronic lock 100, and improving the reliability of opening and closing.

[0042] The clutch mechanism 4 can be connected to the door handle, and the user can turn the door handle to open and close the first lock tongue assembly 2 and the second lock tongue assembly 3. That is, in the engaged state, the user turns the door handle to realize the linkage of the clutch mechanism 4, and the clutch mechanism 4 drives the first lock tongue assembly 2 and the second lock tongue assembly 3 to retract into the housing 1 to unlock; in the disengaged state, the clutch mechanism 4 cannot be linked to the first lock tongue assembly 2 and the second lock tongue assembly 3, and the user cannot realize the linkage of the first lock tongue assembly 2 and the second lock tongue assembly 3 by turning the door handle, so that the electronic lock 100 is in a locked state.

[0043] In addition, through the first lock tongue assembly 2, the second lock tongue assembly 3, the clutch mechanism 4, the driving mechanism 5 and the reset mechanism 6, the electronic lock 100 can be assembled in a modular manner. On the one hand, it can not only reasonably arrange the internal structural parts of the electronic lock 100, so that the internal space of the electronic lock 100 is simple, but also facilitate the operation and assembly of the electronic lock 100, which is conducive to improving production efficiency.

[0044] The clutch mechanism 4 includes a first connection component 41, a second connection component 42, a third connection member 43 and a clutch component 44. The first connection component 41 and the second connection component 42 are both connected to the third connection member 43, and the third connection member 43 is linked with the first locking tongue component 2 and the second locking tongue component 3. The clutch component 44 is movably connected to the third connection member 43 and is tactilely matched with the driving mechanism 5. The clutch component 44 can lock or release the first connection component 41 and the second connection component 42 under the action of the driving mechanism 5, so that the clutch mechanism 4 enters an engaged state or a disengaged state.

[0045] The housing 1 has a mounting side 11, and the mounting side 11 is provided with a first tongue opening 12 communicating with the interior of the housing 1. A first locking portion 211 is formed at one end of the first locking tongue 21, and the first tongue opening 12 is for the first locking portion 211 to pass through. The first locking portion 211 is used to lock or unlock a structure such as a door body. The first locking portion 211 can be arranged in an inclined shape, that is, one side surface of the first locking portion 211 is an inclined surface. When the inclined surface abuts against an external object such as a door frame, based on the principle of wedge fit, the abutting force applied by the external object on the inclined surface will drive the first locking portion 211 to move. Especially when closing the door, this principle can be used to automatically close the door, which is convenient to use.

[0046] The first locking portion 211 can extend from the first tongue opening 12 or retract into the housing 1 under the linkage of the third connecting member 43 to achieve the locking or unlocking function of the electronic lock 100. The first lock tongue 21 is sleeved with a spring, and the spring is elastically abutted with the housing 1, so that the first lock tongue 21 can automatically reset, which can not only ensure the reliability of the locking of the first lock tongue 21, but also improve the convenience of use of the electronic lock 100.

[0047] The second lock tongue assembly 3 includes a second lock tongue 31, which is movably connected to the housing 1, and the second connecting assembly 42 is linked with the third connecting member 43. The second lock tongue 31 is provided with a second locking portion 311, which is used to cooperate with the first locking portion 211 to lock or unlock the door body and other structures, so as to realize the locking or unlocking function of the electronic lock 100.

[0048] The mounting side 11 is further provided with a second tongue opening 13 communicating with the interior of the housing 1, and the second tongue opening 13 is for the second locking portion 311 to pass through, and the second locking portion 311 can be extended from the second tongue opening 13 or retracted into the housing 1 under the linkage of the third connecting member 43. The number of the second locking portions 311 can be multiple, such as two, three or more than three, and the second tongue opening 13 can be divided into multiple openings, and the multiple openings are distributed at intervals, and multiple second locking portions 311 pass through the corresponding tongue openings. The second tongue opening 13 can also be arranged in a long strip shape, and the second tongue opening 13 is for multiple second locking portions 311 to pass through.

[0049] The second lock portion 311 can be arranged in a square shape. When connected to the door frame, the abutting force between the door frame and the second lock portion 311 acts perpendicularly on the surface of the second lock portion 311. The abutting force cannot drive the second lock portion 311 to move, so the second lock portion 311 has good safety.

[0050] The electronic lock 100 also includes a lining plate 7, which is fixed to the installation side 11 by screws or glue. The lining plate 7 is arranged in a long strip shape, and is provided with a first avoidance opening 71 and a second avoidance opening 72. The first avoidance opening 71 is arranged corresponding to the first tongue opening 12, and the second avoidance opening 72 is arranged corresponding to the second tongue opening 13. The first avoidance opening 71 is used to avoid the first lock part 211, and the second avoidance opening 72 is used to avoid the second lock part 311. On the one hand, the lining plate 7 can well protect the housing 1, effectively reducing the possibility of the housing 1 being damaged by foreign objects. On the other hand, the lining plate 7 can well decorate the installation side 11, so that the installation side 11 exposed to the outside of the electronic lock 100 is more beautiful as a whole, improving the user's experience.

[0051] Reference Figures 1 to 9 The electronic lock 100 further includes a transmission member 4211 and a swing member 422 , the transmission member 4211 and the swing member 422 are in transmission cooperation, and the third connecting member 3 is linked with the second bolt assembly 3 through the transmission member 4211 and the swing member 422 .

[0052] The transmission member 4211 is connected to the third connecting member 43, one end of the swing member 422 is in transmission cooperation with the transmission member 4211, and the other end is in linkage cooperation with the second bolt assembly 3. The linkage between the clutch mechanism 4 and the second bolt assembly 3 can be well realized through the transmission member 4211 and the swing member 422, thereby realizing the unlocking and locking functions of the electronic lock 100.

[0053] Among them, the swinging member 422 can be rotatably connected to the housing 1 by installing a pin or a bolt, the swinging member 422 is toothed on one side facing the adapter 421, and the transmission member 4211 is toothed on one side facing the swinging member 422. The swinging member 422 is meshed with the transmission member 4211, that is, the swinging member 422 and the transmission member 4211 are gear-driven to achieve the linkage between the swinging member 422 and the transmission member 4211. Such a setting enables the swinging member 422 and the transmission member 4211 to have stable and efficient transmission performance, so as to ensure the smooth linkage between the clutch mechanism 4 and the second bolt assembly 3, effectively reduce the possibility of failure in opening and closing the lock of the electronic lock 100, and improve the reliability of the use of the electronic lock 100.

[0054] It can be understood that the swinging member 422 and the transmission member 4211 can also be connected by a connecting rod mechanism to achieve the linkage between the swinging member 422 and the transmission member 4211. The swinging member 422 and the transmission member 4211 can also be connected by other structures for transmission. As long as the linkage performance between the swinging member 422 and the transmission member 4211 can be guaranteed, no specific limitation is made here.

[0055] The swinging member 422 is provided with a sliding portion 4221, and the second locking tongue 31 is provided with a sliding groove 312, the sliding groove 312 is arranged in an arc shape, and the sliding portion 4221 is arranged in the sliding groove 312 and slidably cooperates with the groove wall of the sliding groove 312. In this way, when the swinging member 422 swings, the sliding portion 4221 can push the inner wall of the sliding groove 312 to move the second locking tongue 31, so as to drive the second locking portion 311 of the second locking tongue 31 to retract or extend out of the shell 1, so as to realize the opening and closing locking function of the electronic lock 100.

[0056] With such arrangement, the purpose of converting the rotational motion of the swinging member 422 into the linear motion of the second locking tongue 31 is achieved through a simple mechanical mechanism, which is easy to implement and also has a compact structure.

[0057] It is understandable that the swinging member 422 and the second locking tongue 31 may also be connected to convert the rotational motion into linear motion through other transmission structures, as long as the second locking portion 311 of the second locking tongue 31 can be extended or retracted into the housing 1, which is not limited here.

[0058] Continue to refer to Figures 1 to 9 The reset mechanism 6 includes an elastic member 61 and a contact member 62 . The elastic member 61 is connected to the housing 1 , and the contact member 62 is connected to the elastic member 61 . The contact member 62 elastically contacts and cooperates with the clutch mechanism 4 under the action of the elastic member 61 .

[0059] In this way, during the process of the clutch mechanism 4 linking the first lock tongue assembly 2 and the second lock tongue assembly 3 to move, that is, during the process of the clutch mechanism 4 switching from the unlocked position to the locked position, the elastic member 61 provides a restoring force for the clutch mechanism 4 through the abutment member 62, ensuring that the clutch mechanism 4 can be completely reset to the initial position, effectively avoiding the clutch mechanism 4 being affected by the drooping of the inner and outer handles and causing the clutch mechanism 4 to have an initial position deviation, ensuring that the driving mechanism 5 can smoothly drive the clutch mechanism 4 to switch between the engaged state and the disengaged state, improving the smoothness of the clutch mechanism 4 shifting gears, and improving the smoothness of the electronic lock 100 opening and closing.

[0060] The clutch mechanism 4 includes a first connection component 41, a second connection component 42, a third connection member 43 and a clutch component 44. The first connection component 41 and the second connection component 42 are both connected to the third connection member 43. The third connection member 43 is linked with the first locking tongue 21 component 2 and the second locking tongue 31 component 3. The clutch component 44 is movably connected to the third connection member 43 and is contact-coordinated with the driving mechanism 5. The clutch component 44 can lock or release the first connection component 41 and the second connection component 42 under the action of the driving mechanism 5, so that the clutch mechanism 4 enters an engaged state or a disengaged state.

[0061] The first connecting component 41 and the second connecting component 42 are also elastically abutted against the reset mechanism 6 , that is, the reset mechanism 6 provides a restoring force for the first connecting component 41 and the second connecting component 42 .

[0062] like Figures 1 to 4 As shown, in some embodiments, the elastic member 61 may be a torsion spring, and the abutment member 62 may be a swing piece. The torsion spring is rotatably connected to the housing 1, and the swing piece is rotatably connected to the housing 1. One end of the torsion spring abuts against the housing 1, and the other end abuts against the swing piece. The first connecting component 41 is provided with a first abutment portion 413, and the second connecting component 42 is provided with a second abutment portion 423. Both the first abutment portion 413 and the second abutment portion 423 abut against the swing piece.

[0063] During the process of switching the clutch mechanism 4 from the locked position to the unlocked position, the first abutment portion 413 and the second abutment portion 423 both press against the swing piece, and compress the torsion spring through the swing piece, and the torsion spring stores energy; during the process of switching the clutch mechanism 4 from the unlocked position to the locked position, the torsion spring releases the stored potential energy, so that the swing piece can elastically abut the first abutment portion 413 and the second abutment portion 423, that is, provide a reset restoring force for the first connecting component 41 and the second connecting component 42, so that the first connecting component 41 and the second connecting component 42 can completely return to the initial position, so as to ensure the linkage reliability between the driving mechanism 5 and the clutch mechanism 4, and ensure that the electronic lock 100 can be opened and closed normally.

[0064] like Figure 5 and Figure 6 As shown, in other embodiments, the elastic member 61 may be a spring, and the abutment member 62 may be a push rod. The housing 1 is provided with a branch 14, one end of the spring abuts against the branch 14, and the push rod may be provided with a receiving groove, the notch of the receiving groove is arranged toward the spring, and one end of the spring away from the branch 14 is arranged in the receiving groove and abuts against the bottom of the groove of the receiving groove. The first connecting component 41 is provided with a first abutment portion 413, and the second connecting component 42 is provided with a second abutment portion 423, and both the first abutment portion 413 and the second abutment portion 423 abut against the push rod.

[0065] Among them, one end of the push rod that abuts against the first abutment portion 413 and the second abutment portion 423 is set in a plate shape, so as to ensure sufficient contact with the first abutment portion 413 and the second abutment portion 423, so that the push rod can stably elastically abut the first abutment portion 413 and the second abutment portion 423 under the action of the spring.

[0066] During the process of switching the clutch mechanism 4 from the locked position to the unlocked position, the first abutting portion 413 and the second abutting portion 423 both press the abutting rod, and compress the spring through the abutting rod, and the spring stores energy; during the process of switching the clutch mechanism 4 from the unlocked position to the locked position, the spring releases the stored potential energy, so that the abutting rod can elastically abut the first abutting portion 413 and the second abutting portion 423, that is, provide a reset restoring force for the first connecting component 41 and the second connecting component 42, so that the first connecting component 41 and the second connecting component 42 can completely return to the initial position, so as to ensure the linkage reliability between the driving mechanism 5 and the clutch mechanism 4, and ensure that the electronic lock 100 can be opened and closed normally.

[0067] It is understandable that the elastic member 61 and the abutment member 62 may also be other structural members that provide restoring force for the clutch mechanism 4 , as long as it is ensured that the clutch mechanism 4 can be completely returned to the initial position, and no specific limitation is made here.

[0068] Reference Figures 1 to 9 The housing 1 is provided with a guide portion 15, which is used to guide the movement of the abutment member 62. This arrangement enables the abutment member 62 to move stably, ensures the stability of the abutment member 62 elastically abutting the first connecting component 41 and the second connecting component 42, enables the clutch mechanism 4 to smoothly return to the initial position, and improves the smoothness and accuracy of the driving mechanism 5 driving the clutch mechanism 4 to enter the engagement state.

[0069] like Figures 1 to 4As shown, when the abutment member 62 is a swing piece, the guide portion 15 can be a guide hole, which is arranged in an arc shape, and the extension direction of the guide hole is consistent with the rotation path of the swing piece. The swing piece is provided with a guide portion, which extends into the guide hole and cooperates with the guide hole. Through the cooperation of the guide portion and the guide hole, the swing piece can rotate along a predetermined path, which effectively prevents the swing piece from getting stuck during the rotation process, improves the smoothness of the swing piece's rotation, and helps to improve the reliability of the abutment clutch mechanism 4.

[0070] like Figure 5 and Figure 6 As shown, when the abutment member 62 is a push rod, the guide portion 15 can be a guide notch, the housing 1 is provided with a guide block 19, the guide notch is formed in the guide block 19, and the push rod passes through the guide notch. Such a configuration enables the push rod to move along a predetermined path, which effectively prevents the push rod from getting stuck during movement, improves the smoothness of the push rod movement, and helps to improve the reliability of the push-to-clutch mechanism 4.

[0071] Continue to refer to Figures 1 to 9 The housing 1 is further provided with a limiting portion 16, which is used to limit the abutment member 62. With such a configuration, on the one hand, the limiting portion 16 can limit the movement stroke of the abutment member 62, such as limiting the linear movement stroke or rotation stroke of the abutment member 62, so that the abutment member 62 can elastically abut the clutch mechanism 4 within a reasonable movement range; on the other hand, the limiting portion 16 effectively stops the abutment member 62, ensuring the reliability of the abutment between the clutch mechanism 4 and the abutment member 62 when switching between the engaged state and the disengaged state, so that the abutment member 62 provides a stable restoring force for the clutch mechanism 4 under the action of the elastic member 61.

[0072] like Figure 2 As shown, when the abutment member 62 is a swing piece, the limiting portion 16 can be a limiting block, which is arranged adjacent to the edge of the guide hole, and can stop the swing piece.

[0073] like Figure 6 As shown, when the abutment member 62 is a push rod, the limiting portion 16 can be a limiting wall, which is formed on the side wall of the guide portion facing the branch 14. The push rod is provided with a limiting flange, which is arranged around the edge of the slot of the accommodating slot, and the limiting flange is limitedly matched with the limiting wall.

[0074] Continue to refer to Figures 1 to 9 The driving mechanism includes a first detection member 51, a second detection member 52 and a third detection member 53. The first detection member 51 is provided corresponding to the first connecting component 41 and is used to detect the rotation state of the first connecting component 41. The second detection member 52 is provided corresponding to the second connecting component 42 and is used to detect the rotation state of the second connecting component 42. The third detection member 53 is provided corresponding to the second locking tongue component 3 and is used to detect the movement state of the second locking tongue component 3.

[0075] With such arrangement, the movement state of the first connecting component 41 and the second connecting component 42 can be detected in real time through the first detecting member 51 and the second detecting member 52, that is, the upper body or downward pressure signal of the inner and outer handles can be detected in real time to realize applications in different occasions and system control applications; the movement state of the second lock tongue component 3 can be detected in real time through the third detecting member 53 to realize monitoring of the opening and closing locking status of the second lock tongue 31, providing users with a monitorable usage experience.

[0076] Specifically, the first detection member 51, the second detection member 52 and the third detection member 53 can all be contact switches, such as mechanical touch switches, toggle switches or collision switches; the first detection member 51, the second detection member 52 and the third detection member 53 can all be non-contact switches, such as infrared-controlled switches, magnetic switches, photoelectric switches, etc.

[0077] Continue to refer to Figures 1 to 9 The driving mechanism 5 includes a box body 54, a driving assembly 55 and a control assembly 56. The driving assembly 55 and the control assembly 56 are both arranged in the box body 54, and the driving assembly 55 and the control assembly 56 are electrically connected. The driving assembly 55 is used to drive the clutch mechanism 4 to switch between the engaged state and the disengaged state, and the control assembly 56 is used to control the driving assembly 55 to work after receiving an external control instruction.

[0078] Such arrangement can provide intelligent operation for the user. The user only needs to operate the drive mechanism 5 on the keyboard or the mobile phone that is connected to the control component 56 for communication. In this way, the user can intelligently operate the drive mechanism 5, so that the drive mechanism 5 can shift up or down the clutch mechanism 4 after receiving the corresponding control instruction, that is, drive the clutch mechanism 4 to switch between the engaged state and the disengaged state.

[0079] The driving assembly 55 includes a motor 551, a gear set 552 and a driving rod 553. The motor 551 is connected to the driving rod 553 through the gear set 552. The driving rod 553 is used to drive the clutch mechanism 4 into an engaged state, or switch from an engaged state to a disengaged state, so as to achieve upshifting or downshifting of the clutch mechanism 4.

[0080] The motor 551 is electrically connected to the control component 56 . The control component 56 may be an electric control module. The electric control module may be designed with reference to electronic locks in the prior art.

[0081] Continue to refer to Figures 1 to 9 The driving mechanism 5 also includes a battery 57. The first detecting member 51, the second detecting member 52, the third detecting member 53, the driving assembly 55 and the control assembly 56 are all electrically connected to the battery 57. The battery 57 can be detachably installed in the box body 54 or the shell 1.

[0082] For example, the battery 57 can be removably installed in the box body 54, the box body 54 is provided with a battery 57 compartment 541, the installation side 11 is provided with an installation port connected to the battery 57 compartment 541, the battery 57 is arranged in the battery 57 compartment 541, and the installation port is covered by a cover plate to seal the battery 57 compartment 541, thereby ensuring the safe use of the battery 57.

[0083] The battery 57 is detachably mounted in the housing 1. The mounting side 11 is provided with a mounting compartment 17. The battery 57 is disposed in the mounting compartment 17. The battery 57 is electrically connected to the first detection member 51, the second detection member 52, the third detection member 53, the drive assembly 55, and the control assembly 56 through a wire. The mounting side 11 is rotatably connected to a battery 57 cover, and the battery 57 cover is used to cover or open the opening of the mounting compartment 17 so that the battery 57 can be replaced or maintained.

[0084] With such arrangement, the battery 57 is designed to be replaceable, so as to facilitate becoming an independent lock system, and can be used in conjunction with external devices such as a panel to become a dual system.

[0085] Continue to refer to Figures 1 to 9 The electronic lock 100 also includes a mechanical lock core 8 connected to the housing 1, the clutch mechanism 4 is linked to the mechanical lock core 8, the mechanical lock core 8 is for a key to be inserted, and the key is used to drive the mechanical lock core 8 to rotate when subjected to an external force, so that the first lock tongue assembly 2 and the second lock tongue assembly 3 can be unlocked or locked.

[0086] This arrangement enables emergency unlocking to be achieved through the mechanical lock core 8 when the clutch mechanism 4 is not smoothly engaged or fails, so as to ensure that the electronic lock 100 can be opened and closed. Similarly, the same is true when the drive mechanism 5 fails.

[0087] The housing 1 is provided with a lock core hole 18, and the lock core hole 18 is arranged adjacent to the swinging member 422 and the clutch mechanism 4, and the mechanical lock core 8 is arranged in the lock core hole 18. The first connecting component 41 includes a first connecting member 412, and the electronic lock 100 also includes a first toggle member 411. The third connecting member 43 is linked with the first lock tongue component 2 through the first toggle member 411. One end of the first toggle member 411 is linked with the first lock tongue 21, and the other end is formed with a first toggle portion 4111. A second toggle portion 4222 is formed on one side of the swinging member 422 close to the lock core hole 18, and both the first toggle portion 4111 and the second toggle portion 4222 are linked with the mechanical lock core 8.

[0088] The specific structure of the mechanical lock core 8 is not shown in the drawings of the present embodiment. The mechanical lock core 8 can select a suitable mechanical lock core 8 in the prior art according to actual needs, and will not be described in detail here.

[0089] When the mechanical lock core 8 moves, the mechanical lock core 8 can control the movement of both the first lock tongue 21 and the second lock tongue 31. The movement of the mechanical lock core 8 is controlled by the key, thereby controlling the movement of the first lock tongue 21. At the same time, since the mechanical lock core 8 can also control the movement of the second lock tongue 31, when the clutch mechanism 4 is in the engaged state, the movement of the first toggle member 411 can be directly controlled by the mechanical lock core 8, thereby controlling the movement of the second lock tongue 31.

[0090] Continue to refer to Figures 1 to 9 The clutch mechanism 4 includes a first connection component 41, a second connection component 42, a third connection component 43 and a clutch component 44. The first connection component 41 and the second connection component 42 are both connected to the third connection component 43. The third connection component 43 is linked with the first locking tongue 21 component 2 and the second locking tongue 31 component 3. The clutch component 44 is movably connected to the third connection component 43 and is contact-coordinated with the driving mechanism 5. The clutch component 44 can lock or release the first connection component 41 and the second connection component 42 under the action of the driving mechanism 5, so that the clutch mechanism 4 enters an engaged state or a disengaged state.

[0091] Specifically, the first connecting component 41 can be connected to the inner door handle, and the second connecting component 42 can be connected to the outer door handle. When the clutch mechanism 4 is in the engaged state, rotating the inner door handle or the outer door handle can realize the linkage of the first lock tongue 21 component 2 and the second lock tongue 31 component 3 to achieve unlocking; in the separated state, the first connecting component 41 and the second connecting component 42 are idle relative to the third connecting member 43. In this case, the user cannot operate the inner door handle or the outer door handle to unlock. When the clutch mechanism 4 is in the separated state, it can be unlocked by the mechanical lock core 8.

[0092] The clutch assembly 44 may include a clutch 441 and a return spring 442. The clutch 441 is movably connected to the third connection member 43. The clutch 441 can be inserted into or withdrawn from the third connection member 43. The return spring 442 is connected between the clutch 441 and the third connection member 43. The return spring 442 is used to drive the clutch 441 to reset. When the clutch 441 is inserted into the third connection member 43, the clutch mechanism 4 is in an engaged state, and when the clutch 441 is disengaged from the third connection member 43, the clutch mechanism 4 is in a disengaged state.

[0093] The end of the driving rod 553 facing the third connecting member 43 has a curved surface, and the shape of the curved surface satisfies that when the driving rod 553 is extended, through the principle of wedge matching, the curved surface can squeeze the clutch 441, so that the clutch 441 is inserted into the third connecting member 43 to achieve gear shifting; when the driving rod 553 is retracted, the curved surface moves away from the clutch 441, and under the action of the return spring 442, the clutch 441 is disengaged from the third connecting member 43 to achieve gear retraction.

[0094] In the clutch mechanism 4, how the clutch mechanism 4 realizes the engagement or separation of the first connecting member 412, the adapter 421 and the third connecting member 43 with each other so that the first connecting component 41 and the second connecting component 42 can move synchronously or individually. The principle can be referred to the patent application numbers 202110742305.X, 202110742314.9, 202111350966.4 or 202111350983.8, which will not be elaborated here.
