Description

Technical Field

[0001] The present application relates to the technical field of lock devices, and in particular to a Type-C self-driving electronic lock cylinder and a lock thereof. Background Art

[0002] Locks are widely used in many fields due to their convenience and safety. Locks usually include a lock core and an unlocking mechanism for realizing the unlocking function. In locks with electronic components, it is common to use the interface of an electronic key to connect to the lock core module of the lock core to obtain the permission to rotate the lock core module.

[0003] In the existing passive lock core, its lock core module will lock the lock core module and the shell assembly through the driving element. When the lock core is unlocked by using the electronic key, the lock core module and the electronic key establish an electrical connection. The lock core module obtains the electrical energy of the electronic key and identifies the electronic key, and then controls the driving element to unlock the lock core module and the shell assembly. Finally, the electronic key is rotated to rotate the lock core module to drive the unlocking mechanism to realize the unlocking operation.

[0004] However, when the lock core module is a Type-C electronic lock core, the Type-C interface is an electronic component and cannot directly bear the force of the electronic key turning. Otherwise, it is easy to damage the Type-C interface and make its electrical connector loose or even break. According to the usage scenario of the Type-C electronic lock, the miniaturization design of the Type-C electronic lock core also makes the corresponding driving element (motor or solenoid, etc.) miniaturized. The driving force of the driving element is affected, which makes the unlocking mechanism stuck and immobile more prominent, thereby limiting the rotation of the drive shaft.

[0005] In summary, the driving failure problem of the unlocking mechanism in the above-mentioned Type-C electronic lock core needs to be solved urgently, especially the miniaturized Type-C self-driving electronic lock core, which can complete the unlocking operation without twisting the Type-C electronic lock core. Summary of the invention

[0006] The main purpose of the present application is to provide a Type-C self-driving electronic lock core, which aims to improve the existing lock core. If the unlocking mechanism fails and gets stuck, it is necessary to turn the electronic key again to drive the lock core module to drive the unlocking mechanism after the unlocking mechanism failure is resolved to achieve the unlocking operation.

[0007] To achieve the above-mentioned purpose, the Type-C self-driving electronic lock core proposed in the present application is applied to a lock, and the Type-C self-driving electronic lock core includes a housing assembly, a lock core module, an elastic member and an output shaft; wherein, The housing assembly is provided with an installation cavity and a connection hole and an operation hole respectively communicated with the installation cavity; The lock core module is installed in the installation cavity, and the lock core module includes a Type-C interface, a control component and a drive component.

The driving shaft rotates along the second direction to drive the driving block to abut against the second elastic arm, so that the first elastic arm abuts against the abutment block.

[0010] In some embodiments of the present application, the first elastic arm and the second elastic arm are both located inside the spiral coil and are arranged adjacent to each other, and the first elastic arm and the second elastic arm are also extended along the axial direction of the spiral coil; The driving block is provided on the circumferential side of the driving shaft, a torsion spring groove is provided on the side of the output shaft facing the driving shaft, the abutment block is protruding from the bottom wall of the torsion spring groove, the torsion spring is at least partially sleeved on the circumferential side of the driving shaft and at least partially accommodated in the torsion spring groove, and the driving block and the abutment block are both located on the inner sides of the first elastic arm and the second elastic arm.

[0011] In some embodiments of the present application, the mounting cavity is provided with a rotating mounting portion, the peripheral wall of the rotating mounting portion is provided with a first limiting portion, the output shaft is rotatably mounted on the rotating mounting portion, and is provided with a second limiting portion movably abutting against the first limiting portion to limit the rotation range of the output shaft.

[0012] In some embodiments of the present application, the first limiting portion is protruding from the peripheral wall of the rotating mounting portion and extending along the circumference of the rotating mounting portion, and the first limiting portion is further formed with an avoidance notch portion on the peripheral wall of the rotating mounting portion; The output shaft includes a rotating body, which is rotatably mounted on the rotating mounting portion and abuts against the first limiting portion. The rotating body is also protruding with the second limiting portion, which is accommodated in the avoidance notch portion. The second limiting portion is movably abutted against two ends of the first limiting portion respectively to limit the rotation range of the output shaft.

[0013] In some embodiments of the present application, the housing assembly includes a bottom shell and a cover plate, the bottom shell is provided with a mounting groove, the cover plate is connected to the bottom shell and covers the mounting groove to enclose and form the mounting cavity; The bottom wall of the mounting groove is provided with the connecting hole, and the cover plate is provided with the operating hole, so that the operating end of the output shaft can be extended out to be connected with the unlocking mechanism of the lock.

[0014] In some embodiments of the present application, the output shaft rotates relative to the unlocking mechanism and has an unlocked state and a locked state. The lock core module also includes a detection component, which is electrically connected to the control component, and the detection component is used to detect whether the output shaft is in the unlocked state or the locked state.

[0015] In some embodiments of the present application, a transparent window is further provided on the bottom wall of the mounting groove, and the detection component includes a status indicator, and the status indicator displays the detection result of the detection component through the transparent window.

[0016] The present application also proposes a lock, which includes an unlocking mechanism and the Type-C self-driving electronic lock core described in any one of the above items, wherein the lock also has a mounting hole, the Type-C self-driving electronic lock core is installed in the mounting hole, and the output shaft is transmission-connected to the unlocking mechanism to drive the unlocking mechanism to realize the unlocking operation.

[0017] In some embodiments of the present application, an annular groove is concavely formed on the circumferential side of the shell assembly, and the shell assembly further includes a sealing ring, which is embedded in the annular groove and at least partially extends out of the annular groove.

[0018] The Type-C self-driving electronic lock core provided in the embodiment of the present application is arranged with the above-mentioned structure. When the unlocking mechanism of the lock is in a normal state, the operator can use an external device to connect with the Type-C interface to control the operation of the driving component, so as to drive the output shaft to rotate through the transmission action of the elastic member, thereby realizing the unlocking operation of the unlocking mechanism; when the unlocking mechanism fails and is stuck, the operator can use an external device to connect with the Type-C interface to control the operation of the driving component. Since the unlocking mechanism fails and is stuck, the rotation of the output shaft is restricted. Therefore, the driving component cannot drive the output shaft to rotate through the transmission action of the elastic member. At this time, the elastic member will be elastically deformed by the force of the driving component and the output shaft, thereby storing elastic potential energy. When the rotation restriction of the output shaft is released, since the resistance to the rotation of the output shaft disappears, the output shaft will continue to complete the unfinished rotation under the action of the elastic force generated by the release of the elastic potential energy, thereby driving the unlocking mechanism to move, thereby realizing the unlocking operation of the unlocking mechanism. It can be seen that the technical solution of the present application can store elastic potential energy through the elastic deformation of the elastic part when the rotation of the output shaft is restricted, and can drive the output shaft to continue to complete the unfinished rotation through the elastic potential energy stored in the elastic part when the rotation restriction of the output shaft is released, so as to realize the unlocking operation of the unlocking mechanism. Compared with the prior art, it is not necessary to turn the electronic key to drive the lock core module to drive the unlocking structure after the unlocking mechanism failure is released, so as to realize the unlocking operation of the unlocking mechanism. At the same time, since the lock core module and the shell assembly are not rotationally connected, when designing the Type-C self-driving electronic lock core, the static sealing structure of the Type-C self-driving electronic lock core is designed at the Type-C interface, that is, the sealing of the Type-C self-driving electronic lock core can be realized, and there is no need to consider the dynamic sealing of the Type-C self-driving electronic lock core, which improves the reliability of the Type-C self-driving electronic lock core and reduces the design difficulty.

[0026] The embodiment of the present application provides a Type-C self-driving electronic lock core 100, which is applied to a lock 1000 and used in conjunction with an unlocking mechanism 200 of the lock 1000. Figures 2 to 7 In an embodiment of the present application, the Type-C self-driving electronic lock core 100 includes a housing assembly 10 , a lock core module 20 , an elastic member and an output shaft 40 .

[0027] The shell assembly 10 is provided with an installation cavity 13 and a connection hole 1111 and an operation hole 121 respectively connected to the installation cavity 13. The shell assembly 10 can be made of hard plastic, or metal material, or a combination of hard plastic and metal material. The installation cavity 13 of the shell assembly 10 is mainly used for installing other components of the Type-C self-driving electronic lock cylinder 100. The shell assembly 10 forms a wrapped protection for the parts in the installation cavity 13, and the installation cavity 13 can be used to improve the sealing performance of the Type-C self-driving electronic lock cylinder 100.

[0028] The lock core module 20 is installed in the installation cavity 13. The lock core module 20 can be fixed in the installation cavity 13 by a screw structure thread connection, and can also be fixed in the installation cavity 13 by a snap connection.

[0029] The lock core module 20 includes a Type-C interface 21, a control component 22 and a drive component 23. The Type-C interface 21 is electrically connected to the control component 22 and is exposed on the outer surface of the shell component 10 through the connecting hole 1111 to dock with an external device. The control component 22 is electrically connected to the drive component 23 to control the operation of the drive component 23 after obtaining authorization.

[0030] The Type-C interface 21 is usually a female socket for external devices to connect. Based on the characteristics of the Type-C interface 21 itself, the control component 22 can establish an electrical connection with the external device through the Type-C interface 21 to obtain the power of the external device, establish a communication connection with the external device, etc. It should be emphasized that when the external device is an electronic key that matches the Type-C self-driving electronic lock cylinder 100, the electronic key can usually be directly connected to the Type-C interface 21. When the external device is a smart phone, tablet computer, laptop computer, power bank, etc., the external device usually also needs a data cable to connect to the Type-C interface 21.

[0031] The control component 22 usually includes an authorization piece, which can usually establish a communication connection with an external device through a wireless or wired connection method and verify the identity of the operator. The control component 22 obtains authorization during identity verification to control the operation of the drive component 23. Specifically, the authorization piece can establish a communication connection with an external device through a wireless connection such as a Bluetooth connection, and the authorization piece can also establish a communication connection with an external device through the Type-C interface 21 mentioned above.

[0032] The output shaft 40 is rotatably mounted in the mounting cavity 13, and partially exposed to the outer surface of the housing assembly 10 through the operating hole 121, so as to be transmission-connected with the unlocking mechanism 200 of the lock 1000. The output shaft 40 can be rotatably mounted in the mounting cavity 13 through bearings and other parts, and the output shaft 40 can also be directly slidably abutted with the mounting cavity 13 to be rotatably mounted in the mounting cavity 13. The portion of the output shaft 40 exposed to the outer surface of the housing assembly 10 is usually an operating end 45, which can be transmission-connected with the unlocking mechanism 200 by plug-in fitting, snap-fit ​​fitting, etc., so that the unlocking mechanism 200 can realize the unlocking operation under the transmission action of the output shaft 40.

[0033] The elastic member is installed between the driving assembly 23 and the output shaft 40, so that the driving assembly 23 drives the output shaft 40 to rotate through the transmission action of the elastic member, and when the rotation of the output shaft 40 is restricted, the elastic potential energy is stored through the elastic deformation of the elastic member, so that when the rotation restriction of the output shaft 40 is released, the output shaft 40 is driven by the elastic potential energy to continue to complete the unfinished rotation.

[0034] Below, the working mode of the Type-C self-driving electronic lock cylinder 100 of the present invention in the normal state of the lock 1000 is described in detail as an example: the operator uses an external device to connect with the Type-C interface 21 to provide the Type-C self-driving electronic lock cylinder 100 with the power required for operation. After obtaining the power, the control component 22 establishes a communication connection with the external device and verifies the identity of the operator. The control component 22 obtains authorization during the identity verification to control the operation of the drive component 23. The drive component 23 applies a force to the elastic member and transmits the force to the output shaft 40 through the elastic member, thereby driving the output shaft 40 to rotate, so that the unlocking mechanism 200 of the lock 1000 realizes the unlocking operation under the driving action of the output shaft 40.

[0035] It should be emphasized that when the control component 22 establishes a communication connection with an external device via a wireless connection, the external device that provides power to the Type-C self-driving electronic lock cylinder 100 and the external device that establishes a communication connection with the Type-C self-driving electronic lock cylinder 100 can be different devices.

[0036] The limited rotation of the output shaft 40 means that the unlocking mechanism 200 of the lock 1000 is stuck due to a fault, resulting in the output shaft 40 being limited in rotation and unable to rotate. It is understandable that the elastic member will undergo elastic deformation when subjected to external force, and store energy, which is usually called elastic potential energy. After the external force is removed or the external force is less than the elastic force provided by the elastic potential energy, the elastic member can return to its original shape, that is, release the elastic potential energy. When releasing the elastic potential energy, the elastic member will output elastic force to the outside. It should be emphasized that the elastic deformation of the elastic member can be a stretched elastic deformation or an extruded elastic deformation.

[0037] The above-mentioned output shaft 40 continues to complete the unfinished rotation means that the output shaft 40 will continue to rotate and rotate to the position where the output shaft 40 is located when the unlocking operation of driving the unlocking mechanism 200 is realized, that is, the output shaft 40 is in the normal state of the lock 1000 and the output shaft 40 drives the unlocking mechanism 200 to realize the unlocking operation, the position of the output shaft 40.

[0038] The Type-C self-driving electronic lock cylinder 100 provided in the embodiment of the present application is provided with the above-mentioned structural setting. When the unlocking mechanism 200 of the lock 1000 is in a normal state, the operator can use an external device to connect with the Type-C interface 21 to control the operation of the driving component 23, so as to drive the output shaft 40 to rotate through the transmission action of the elastic member to realize the unlocking operation of the unlocking mechanism 200; when the unlocking mechanism 200 fails and is stuck, the operator can use an external device to connect with the Type-C interface 21 to control the operation of the driving component 23. In the event of a malfunction, 200 becomes stuck and cannot move, and the rotation of the output shaft 40 is restricted. As a result, the drive assembly 23 cannot drive the output shaft 40 to rotate through the transmission action of the elastic member. At this time, the elastic member is elastically deformed by the action of the drive assembly 23 and the output shaft 40, thereby storing elastic potential energy. When the rotation restriction of the output shaft 40 is released, the resistance to the rotation of the output shaft 40 disappears, and the output shaft 40 will continue to complete the unfinished rotation under the action of the elastic force generated by the release of the elastic potential energy, thereby driving the unlocking mechanism 200 to move, thereby realizing the unlocking operation of the unlocking mechanism 200. It can be seen that the technical solution of the present application can store elastic potential energy through the elastic deformation of the elastic member when the rotation of the output shaft 40 is restricted. When the rotation restriction of the output shaft 40 is released, the elastic potential energy stored in the elastic member can drive the output shaft 40 to continue to complete the unfinished rotation, thereby realizing the unlocking operation of the unlocking mechanism 200. Compared with the prior art, it is not necessary to rotate the electronic key to drive the lock core module 20 to drive the unlocking structure after the unlocking mechanism 200 fails, so as to realize the unlocking operation of the unlocking mechanism 200. At the same time, since the lock core module 20 has no rotational connection with the housing assembly 10, when designing the Type-C self-driving electronic lock core, the static sealing structure of the Type-C self-driving electronic lock core 100 is designed at the Type-C interface 21, that is, the sealing of the Type-C self-driving electronic lock core 100 can be realized, and there is no need to consider the dynamic sealing of the Type-C self-driving electronic lock core 100, which improves the reliability of the Type-C self-driving electronic lock core 100 and reduces the design difficulty.

[0039] In addition, based on the characteristics of the Type-C interface 21 itself, the operator can use external devices such as smart phones, tablet computers, laptops, power banks, etc. and data cables to unlock the Type-C self-driving electronic lock cylinder 100. At the same time, the Type-C interface 21 is small and supports forward and reverse insertion, which also provides a lot of convenience for the operator.

[0040] It should be emphasized that, usually, the operator will not find that the unlocking mechanism 200 is stuck due to a fault when the unlocking operation is not performed. Usually, the operator will find that the unlocking mechanism 200 is stuck due to a fault when performing the unlocking operation, and usually will solve the fault after discovering the problem, so that the rotation restriction of the output shaft 40 is released.

[0041] In some examples, such as Figures 3 to 8 As shown, the driving assembly 23 includes a driving member 231 and a driving shaft 232. The driving member 231 is fixedly installed in the installation cavity 13 and is in transmission connection with the driving shaft 232 to drive the driving shaft 232 to rotate in a first direction or a second direction. The elastic member is installed between the driving member 231 and the output shaft 40. The first direction is opposite to the second direction. Such a configuration is intended to facilitate the installation of the driving shaft 232, the elastic member and the output shaft 40.

[0042] In some examples, the driving shaft 232 is provided with a cross groove 2322 , and the driving rod of the driving member 231 is plugged into and matched with the cross groove 2322 .

[0043] It should be noted that when the output shaft 40 rotates in the first direction to perform an unlocking operation, the output shaft 40 rotates in the second direction to perform a locking operation; when the output shaft 40 rotates in the first direction to perform a locking operation, the output shaft 40 rotates in the second direction to perform an unlocking operation. When the first direction is clockwise, the second direction is counterclockwise; when the first direction is counterclockwise, the second direction is clockwise.

[0044] In some examples, such as Figures 3 to 8 As shown, the elastic member includes a torsion spring 30, and the torsion spring 30 includes a spiral coil 31, a first elastic arm 32 and a second elastic arm 33, and the first elastic arm 32 and the second elastic arm 33 are respectively connected to the two ends of the spiral coil 31. The driving shaft 232 is provided with a driving block 2321, and the output shaft 40 is provided with an abutment block 41. The driving shaft 232 rotates along the first direction to drive the driving block 2321 to abut against the first elastic arm 32, so that the second elastic arm 33 abuts against the abutment block 41, and the driving shaft 232 rotates along the second direction to drive the driving block 2321 to abut against the second elastic arm 33, so that the first elastic arm 32 abuts against the abutment block 41.

[0045] When the lock 1000 is in a normal state, the drive shaft 232 rotates in a first direction to drive the output shaft 40 to rotate in the first direction through the transmission effect of the torsion spring 30, thereby performing an unlocking operation or a locking operation on the unlocking mechanism 200; the drive shaft 232 rotates in a second direction to drive the output shaft 40 to rotate in the second direction through the transmission effect of the torsion spring 30, thereby performing a locking operation or an unlocking operation on the unlocking mechanism 200. In this way, the drive shaft 232 can stably and reliably transmit power to the output shaft 40 through the torsion spring 30, thereby performing an unlocking operation on the unlocking mechanism 200. Of course, in the above process, the torsion spring 30 may also be slightly deformed, storing a small amount of elastic potential energy.

[0046] When the unlocking mechanism 200 is stuck due to a fault, the driving shaft 232 rotates in the first direction, and the driving block 2321 will stretch or squeeze the spiral coil 31 by abutting against the first elastic arm 32, so that the torsion spring 30 stores elastic potential energy. When the rotation restriction of the output shaft 40 is released, the elastic potential energy drives the output shaft 40 to rotate in the first direction, thereby unlocking or locking the unlocking mechanism 200; the driving shaft 232 rotates in the second direction, and the driving block 2321 will stretch or squeeze the spiral coil 31 by abutting against the second elastic arm 33, so that the torsion spring 30 stores elastic potential energy. When the rotation restriction of the output shaft 40 is released, the elastic potential energy drives the output shaft 40 to rotate in the second direction, thereby unlocking or locking the unlocking mechanism 200. In this way, the torsion spring 30 can stably store elastic potential energy and stably release elastic potential energy, and the torsion spring 30 has a simple structure and low manufacturing cost.

[0047] In some examples, such as Figures 3 to 8 As shown, the first elastic arm 32 and the second elastic arm 33 are both located inside the spiral coil 31 and are arranged adjacent to each other. The first elastic arm 32 and the second elastic arm 33 are also extended along the axial direction of the spiral coil 31. A driving block 2321 is provided on the circumferential side of the driving shaft 232, a torsion spring 30 groove is provided on the side of the output shaft 40 facing the driving shaft 232, and an abutment block 41 is convexly provided on the bottom wall of the torsion spring 30 groove. The torsion spring 30 is at least partially sleeved on the circumferential side of the driving shaft 232 and at least partially accommodated in the torsion spring 30 groove. The driving block 2321 and the abutment block 41 are both located inside the first elastic arm 32 and the second elastic arm 33.

[0048] In this way, the torsion spring 30 can be abutted against the bottom wall and the peripheral wall of the torsion spring 30 groove, thereby improving the reliability of the torsion spring 30 installed between the output shaft 40 and the drive shaft 232. Moreover, the torsion spring 30 is restricted by the peripheral wall of the torsion spring 30 groove, and its spiral coil 31 is more stable during the process of being stretched or compressed.

[0049] In some examples, the driving block 2321 and the abutment block 41 are staggered in the axial direction of the spiral coil 31, that is, the driving block 2321 is located on the side of the spiral coil 31 in the axial direction away from the output shaft 40, and the abutment block 41 is located on the side of the spiral coil 31 in the axial direction close to the output shaft 40, so that there is no interference between the driving shaft 232 and the output shaft 40 during rotation.

[0050] It is considered that the output shaft 40 can usually achieve the unlocking operation of the unlocking mechanism 200 within a small rotation range.

[0051] In some examples, such as Figures 3 to 9 As shown, the mounting cavity 13 is provided with a rotating mounting portion 112, and the peripheral wall of the rotating mounting portion 112 is provided with a first limiting portion 1121. The output shaft 40 is rotatably mounted on the rotating mounting portion 112, and is provided with a second limiting portion 44 that movably abuts against the first limiting portion 1121 to limit the rotation range of the output shaft 40. Such a setting is intended to prevent the output shaft 40 from being subjected to excessive force and excessive rotation, thereby damaging the structure of the Type-C self-driving electronic lock cylinder 100 and the structure of the unlocking mechanism 200.

[0052] In some examples, such as Figures 3 to 9 As shown, the first limiting portion 1121 is convexly arranged on the peripheral wall of the rotating mounting portion 112 and extends along the circumferential direction of the rotating mounting portion 112. The first limiting portion 1121 is also formed with an avoidance notch portion 1122 on the peripheral wall of the rotating mounting portion 112. The output shaft 40 includes a rotating body 43, which is rotatably mounted on the rotating mounting portion 112 and abuts against the first limiting portion 1121. The rotating body 43 is also convexly provided with a second limiting portion 44, which is accommodated in the avoidance notch portion 1122. The second limiting portion 44 is respectively movably abutted against two ends of the first limiting portion 1121 to limit the rotation range of the output shaft 40.

[0053] In this way, the first limiting portion 1121 can not only be used to cooperate with the second limiting portion 44 to limit the rotation range of the output shaft 40, but also the first limiting portion 1121 can abut against the rotating body 43 to support the output shaft 40 and improve the stability of the output shaft 40. At the same time, the first limiting portion 1121 can also limit the axial movement of the output shaft 40, further improving the stability of the output shaft 40.

[0054] It can be understood that in this example, the rotation amplitude of the output shaft 40 can be controlled by controlling the size of the avoidance gap 1122. In some examples, the arc length of the avoidance gap is one-quarter of the circumference of a circle, that is, the rotation amplitude of the output shaft 40 is 90°.

[0055] In some examples, such as Figures 3 to 9As shown, the housing assembly 10 includes a bottom shell 11 and a cover plate 12. The bottom shell 11 is provided with a mounting groove 111. The cover plate 12 is connected to the bottom shell 11 and covers the mounting groove 111 to enclose a mounting cavity 13. A connecting hole 1111 is provided on the bottom wall of the mounting groove 111, and an operating hole 121 is provided on the cover plate 12, so that the operating end 45 of the output shaft 40 can extend out to be connected to the unlocking mechanism 200 of the lock 1000. Such a setting is intended to facilitate the assembly of the Type-C self-driving electronic lock cylinder 100 and improve the assembly efficiency of the Type-C self-driving electronic lock cylinder 100.

[0056] In some examples, the bottom shell 11 is an integrated structure, which can further improve the sealing performance of the installation cavity 13; of course, in some other examples, the bottom shell 11 can also be composed of two or more components, and a seal 15 is provided between the components to achieve static sealing of the bottom shell 11, thereby preventing water vapor from entering the interior of the Type-C self-driving electronic lock cylinder 100 through the gaps between the components.

[0057] In some examples, such as Figures 3 to 8 As shown, the output shaft 40 rotates relative to the unlocking mechanism 200 and has an unlocked state and a locked state. The lock core module 20 also includes a detection component 24, which is electrically connected to the control component 22. The detection component 24 is used to detect whether the output shaft 40 is in an unlocked state or a locked state.

[0058] With such a configuration, the status information of the output shaft 40 can be fed back in real time through the detection component 24. When the detection component 24 detects that the output shaft 40 has completed the state switching, it can transmit a signal to the control component 22. The control component 22 controls the driving member 231 to stop working according to the signal to avoid overloading the driving member 231.

[0059] Of course, in some examples, the driving member 231 can be stopped when it is blocked, and remain motionless after stopping. Specifically, when the output shaft 40 is restricted in rotation, the elastic member undergoes elastic deformation under the drive of the driving member 231 and the driving shaft 232 to store enough elastic potential energy, and then the driving member 231 is blocked and stopped, and remains motionless, so that the elastic potential energy of the elastic member is not released.

[0060] In some examples, the detection assembly 24 includes a Hall element, and the Hall element detects whether the output shaft 40 is in the unlocked state or the locked state by detecting the magnet 46 on the output shaft 40 .

[0061] In some examples, the control component 22 may send the detection result of the detection component 24 to an external device so as to monitor the lock 1000 through the external device.

[0062] Considering that the Type-C self-driving electronic lock core 100 can realize the unlocking operation of the unlocking mechanism 200 without rotating the lock core module 20, the operator may not be able to obtain the information of whether the unlocking mechanism 200 completes the unlocking operation in time without rotating the lock core module 20.

[0063] In some examples, such as Figure 2 As shown, the bottom wall of the mounting groove 111 is further provided with a transparent window 1112, and the detection assembly 24 includes a status indicator, which displays the detection result of the detection assembly 24 through the transparent window 1112. With such a configuration, the operator can quickly obtain the detection result of the detection member through the indicator, and then quickly obtain information on whether the unlocking mechanism 200 has completed the unlocking operation. The indicator can be an indicator light, or a display screen, etc.

[0064] Please refer to Figures 1 to 9 , the present application also proposes a lock 1000, which includes an unlocking mechanism 200 and any one of the above-mentioned Type-C self-driving electronic lock cylinders 100. The specific structure of the Type-C self-driving electronic lock cylinder 100 refers to the above-mentioned embodiment. Since the lock 1000 adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here. Among them, the lock 1000 also has a mounting hole 1001, and the Type-C self-driving electronic lock cylinder is installed in the mounting hole 1001, and the output shaft 40 is connected to the unlocking mechanism 200 in a transmission manner to drive the unlocking mechanism 200 to realize the unlocking operation.

[0065] It should be noted that when the Type-C self-driving electronic lock core 100 is applied to the lock 1000, the Type-C self-driving electronic lock core 100 usually has only one side with the Type-C interface 21 exposed on the outer surface of the lock 1000 for the operator to connect with the external device. In some examples, such as Figures 1 to 4 As shown, the housing assembly 10 is provided with an annular groove 113 on the circumferential side thereof, and the housing assembly 10 further includes a sealing ring 14, which is embedded in the annular groove 113 and at least partially extends out of the annular groove 113. With such a configuration, when the Type-C self-driving electronic lock core 100 is applied to the lock 1000, the sealing ring 14 abuts against the hole wall of the mounting hole 1001 of the lock 1000 to form a seal, thereby preventing water vapor and the like from entering from the gap between the Type-C self-driving electronic lock core 100 and the lock 1000.

[0066] The above description is only an optional embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural transformations made by using the contents of the present application specification and drawings under the inventive concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
