Description

Technical Field

[0001] This utility model relates to the technical field of locks, and in particular to an electronic lock with dual position monitoring function. Background Technology

[0002] Electronic locks are widely used in homes, offices, warehouses, and other settings due to their ease of use and high security. Current electronic locks typically monitor the lock's open / closed status using a single position sensor, such as monitoring only the extension / retraction position of the bolt or only the status of the locking mechanism.

[0003] A prior art example, referring to patent document CN120007024A, discloses a retractable concealed electronic lock, including a fixed outer shell having an installation chamber, integrally embedded in a cabinet; a rotating bracket rotatably disposed in the installation chamber; a telescopic shell retractably disposed in the installation chamber, and the telescopic shell can drive the rotating bracket to rotate; an electronic lock assembly communicatively connected to an electronic lock identification component, and having at least a locked state and an unlocked state; an electronic lock identification component responding to a user's first unlocking operation; a mechanical locking assembly mounted on the rotating bracket; an elastic component acting on the telescopic shell; and a state switching mechanism disposed between the rotating bracket and the telescopic shell, having at least a restricted movement state and a released position state. However, this technical example lacks position monitoring functionality during extension and retraction; if the movement is not in place, the lock will malfunction.

[0004] However, single-location monitoring has significant drawbacks: when the sensor malfunctions or is interfered with, it can easily lead to misjudgments of the lock's status, potentially resulting in "false locking" (appearing locked but actually unlocked) or "false opening" (appearing open but actually not open), severely impacting the lock's security and reliability. Furthermore, a single sensor cannot simultaneously and accurately reflect both the stop / release state of the locking mechanism and the extension / retraction state of the lock body components, failing to meet the refined monitoring requirements of high-security scenarios.

[0005] Therefore, there is an urgent need for an electronic lock that can achieve multi-position monitoring and improve the accuracy and reliability of status monitoring. Summary of the Invention

[0006] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides an electronic lock with dual position monitoring function, which aims to solve the technical problems of inaccurate status judgment, insufficient security and reliability caused by single position monitoring in existing electronic locks.

[0007] The technical solution of this utility model to solve its technical problem is: an electronic lock with dual position monitoring function, comprising:

[0008] The lock housing is assembled onto the cabinet body via a mounting bracket;

[0009] A control circuit board is disposed in the lock housing;

[0010] A rotary switch is capable of telescopic movement relative to the lock body component, such that the rotary switch has at least an extended position and a retracted position relative to the lock housing.

[0011] The lock body component is located at the rear end of the lock housing and forms a transmission engagement with the rotary switch;

[0012] A stop mechanism is provided in the lock housing. The stop mechanism acts on the rotary switch and has at least a stop position state and a release position state relative to the rotary switch.

[0013] It also includes:

[0014] The first position sensor is connected to the control circuit board and is in position sensing cooperation with the stop mechanism.

[0015] The second position sensor is connected in communication with the control circuit board and is in position sensing cooperation with the lock body component.

[0016] In a preferred embodiment, the first position sensor is a first contact sensor, and the second position sensor is a second contact sensor;

[0017] When the stop mechanism is in the released position, it contacts the first contact sensor and forms a position sensing engagement; when the stop mechanism is in the stopped position, it separates from the first contact sensor.

[0018] When the rotary switch is in the retracted position, it contacts the second contact sensor and forms a position sensing engagement; when the rotary switch is in the extended position, it separates from the second contact sensor.

[0019] In some preferred embodiments of this utility model, a driving block protrudes from the side wall of the rotary switch, and a movable feedback component is provided in the lock housing.

[0020] The feedback component has a feedback end and a driving end. The driving end of the feedback component forms a contactable transmission connection with the driving block, and the feedback end of the feedback component forms a position sensing connection with the second position sensor.

[0021] Optionally, the feedback component is a rocker, the middle part of which is rotatably connected to the lock housing via a rotating shaft, and a reset torsion spring is provided between the rocker and the lock housing;

[0022] When the rotary switch lock housing enters the retracted position, the drive block contacts the drive end of the feedback component and drives the feedback component to approach the second position sensor, so that the second position sensor senses the position change of the feedback end of the feedback component.

[0023] When the rotary switch lock housing exits the retracted position, the drive block moves away from the drive end of the feedback component. Under the action of the reset torsion spring, the feedback component moves away from the second position sensor, so that the second position sensor can sense the position change of the feedback end of the feedback component.

[0024] In some preferred embodiments of this utility model, the stopping mechanism includes a driving device, a linkage block, and a stopping execution block;

[0025] The drive device is fixedly installed in the lock housing, and the drive device has an eccentric output shaft;

[0026] The linkage block is connected between the eccentric output shaft and the stop actuator block. Driven by the eccentric output shaft, the linkage block has a rising position state and a falling position state.

[0027] When the linkage block is in the rising position, the linkage block contacts the first position sensor and forms a position sensing engagement, and the stop execution block is offset from the rotary switch so that the rotary switch can perform telescopic movement.

[0028] When the linkage block is in the lowered position, the linkage block separates from the first position sensor, and the stop actuator abuts against the rotary switch and forms a position interference engagement to restrict the rotary switch from extending or retracting.

[0029] Optionally, a stop block is provided on the side wall of the rotary switch, and the stop block can be offset from or abut against the position of the stop actuator block.

[0030] Preferably, the rotary switch includes an operating section and a transmission section, the operating section being located at the front end of the transmission section, and the transmission section being movably disposed within the lock housing;

[0031] The lock body component includes a guide section and a latch section. The latch section is fixedly installed to the rear end of the guide section. A telescopic drive elastic element is provided between the front end of the guide section and the rear end of the transmission section. The telescopic drive elastic element acts on the transmission section so that the rotating switch always has a tendency to move away from the lock body component.

[0032] It is worth mentioning that when the rotary switch is in the extended position relative to the lock housing, the transmission section can transmit torsional force to the lock body component through the telescopic drive elastic element, so that the lock body component and the rotary switch form a transmission engagement.

[0033] In some preferred embodiments of this utility model, the lock housing is provided with a through hole, and the transmission section is movably inserted through the through hole;

[0034] The inner wall of the through hole is provided with guide ribs, and the transmission section is provided with straight guide grooves distributed along the extension and retraction direction of the rotary switch. The guide ribs are slidably fitted in the straight guide grooves.

[0035] The transmission section is also provided with a rotating groove, which is connected to the end of the straight guide groove. When the rotary switch is in the extended position, the guide rib is located in the rotating groove and can move along the rotating groove.

[0036] In some preferred embodiments of the present invention, the rear end of the transmission section has a first arc-shaped guide end face, and the front end of the guide section is provided with a second arc-shaped guide end face;

[0037] When the rotary switch is in the retracted position, the first arc-shaped guide end face is always at least partially in contact with the second arc-shaped guide end face;

[0038] When the rotary switch is in the extended position, the first arc-shaped guide end face and the second arc-shaped guide end face are offset to allow the rotary switch to rotate.

[0039] The working process of this utility model is as follows:

[0040] Locking process: The user pushes the operating section of the rotary switch, causing it to retract into the housing against the elastic force of the telescopic drive element (the guide rib of the transmission section slides along the guide groove); the drive block pushes the drive end of the feedback component, causing the feedback component to rotate, and the feedback end contacts the second position sensor, sending a "retract" signal (the lock body component retracts synchronously, not locked); at this time, the control circuit board controls the drive device to drive the eccentric output shaft to rotate, the linkage block descends (separates from the first position sensor, sending a "stop" signal), the stop execution block abuts against the stop block, restricting the rotary switch from extending; the user rotates the operating section, the guide rib of the transmission section moves along the rotation groove, transmits torque through the arc-shaped guide end face, and drives the lock body component to rotate to the locking angle; the user releases the operating section, and under the action of the telescopic drive element, the rotary switch extends (the guide rib returns to the guide groove), the lock body component extends synchronously and inserts into the lock hole, the drive block moves away from the feedback component, and the feedback end separates from the second position sensor under the action of the reset torsion spring, sending a "extend" signal, completing the locking.

[0041] Unlocking process: After the control circuit board receives the unlocking command, the drive device drives the eccentric output shaft to rotate in the opposite direction, the linkage block rises (contacts the first position sensor and sends a "release" signal), and the stop execution block and the stop block are misaligned; the user pushes the rotary switch to retract (the feedback end contacts the second position sensor and sends a "retract" signal), the rotation operation section drives the lock body component to rotate to the unlocking angle, after release the rotary switch extends, the lock body component retracts synchronously, the feedback end separates from the second position sensor (sends a "extend" signal to complete unlocking).

[0042] Status monitoring: The control circuit board receives signals from the first position sensor (stop / release) and the second position sensor (extend / retract) in real time. When the signal combination is abnormal (such as the "stop" signal and the "retract" signal appearing at the same time), an alarm is triggered.

[0043] The beneficial effects of this utility model are as follows:

[0044] 1. Dual monitoring for accurate status: The first position sensor monitors the stop / release status of the stop mechanism, and the second position sensor monitors the extension / retraction status of the lock body components. The dual signals are fed back to the control circuit board to achieve a comprehensive and accurate judgment of the lock status, avoiding misjudgments caused by the failure of a single sensor.

[0045] II. Enhanced Security: Dual position monitoring can effectively prevent "false locking" and "false opening" phenomena. For example, when the first sensor detects that the stop mechanism is in the "stopped" state but the second sensor detects that the lock body component is not "extended" (not locked), the control circuit board can trigger an alarm to indicate that the lock is abnormal.

[0046] III. Reliable structure and stable transmission: Through structural design such as feedback components, arc-shaped guide end face, guide ribs and guide grooves, the position signal transmission is ensured to be accurate, and the extension and rotation of the rotary switch and lock body components are smooth and reliable.

[0047] IV. Wide applicability: It can be adapted to various door and cabinet scenarios, meeting the requirements of high security needs (such as warehouses, important document cabinets, etc.) for refined monitoring of lock status. Attached Figure Description

[0065] Example 1

[0066] Reference Figures 1 to 13 An electronic lock with dual position monitoring function includes:

[0067] The lock housing 1 (generally composed of a front housing 11 and a rear cover 12) is assembled onto the door cabinet via a mounting base 14, providing space for the installation and protection of the various components inside the lock, enabling each component to work in a relatively stable environment.

[0068] The control circuit board 2 is disposed in the lock housing 1; as the control core of the electronic lock, it can receive and process various signals, thereby regulating the operating status of the lock.

[0069] The rotary switch 3 is capable of telescopic movement relative to the lock body component 4, such that the rotary switch 3 has at least an extended position 3a and a retracted position 3b relative to the lock housing 1. When the rotary switch 3 is in the extended position 3a, it corresponds to the state where the door cabinet can be unlocked; when it is in the retracted position 3b, it corresponds to the state where the door cabinet (stop mechanism 5 and / or lock body component 4) can be locked.

[0070] The lock body component 4 is located at the rear end of the lock housing 1. The lock body component 4 and the rotary switch 3 form a transmission connection. The rotational movement of the rotary switch 3 after it is extended can drive the lock body component 4 to move accordingly, thereby realizing the locking and unlocking of the door cabinet.

[0071] A stop mechanism 5 is disposed in the lock housing 1. The stop mechanism 5 acts on the rotary switch 3, and the stop mechanism 5 has at least a stop position state 5a and a release position state 5b relative to the rotary switch 3. When the stop mechanism 5 is in the stop position state 5a, it can restrict the extension and retraction movement of the rotary switch 3 to ensure the stability of the rotary switch 3 in a specific state. When it is in the release position state 5b, the rotary switch 3 can freely extend and retract.

[0072] The first position sensor 6 is connected to the control circuit board 2 in communication and is in position sensing cooperation with the stop mechanism 5. The first position sensor 6 can sense the position state of the stop mechanism 5 in real time and transmit the sensed signal to the control circuit board 2, so that the control circuit board 2 can accurately monitor whether the stop mechanism 5 is in the stop position state 5a or the release position state 5b.

[0073] The second position sensor 7 is communicatively connected to the control circuit board 2 and forms a position sensing cooperation with the lock body component 4. The second position sensor 7 can sense the position change of the lock body component 4 in real time, thereby indirectly reflecting the extension and retraction state of the rotary switch 3, and transmitting the relevant signals to the control circuit board 2, so that the control circuit board 2 can monitor the position of the rotary switch 3 relative to the lock housing 1.

[0074] The above content constitutes the basic solution of this utility model. Compared with the prior art, it has at least the following beneficial effects: 1. Improved monitoring accuracy: By setting a first position sensor 6 and a second position sensor 7, the position status of the stop mechanism 5 and the extension / retraction status of the rotary switch 3 (indirectly reflected through the lock body component 4) are monitored respectively, realizing dual position monitoring. Dual monitoring can mutually verify each other, effectively avoiding misjudgments that may occur with a single monitoring method, and greatly improving the accuracy of monitoring the status of the electronic lock. 2. Enhanced lock security: Since the status of the stop mechanism 5 and the rotary switch 3 can be accurately grasped, the control circuit board 2 can precisely control the lock based on this accurate information. When abnormal situations occur, they can be detected in time and corresponding measures can be taken. For example, when the stop mechanism 5 should be in the stop position but is not in that position, or when the extension / retraction status of the rotary switch 3 does not conform to the expectation, an alarm can be issued in time or corresponding error correction operations can be performed, thereby enhancing the security of the electronic lock. 3. Improved lock reliability: Dual position monitoring reduces the possibility of the entire monitoring system failing due to the failure of a single sensor. Even if one position sensor malfunctions, the other position sensor can still provide relevant status information to a certain extent, which helps to ensure the basic operation and status monitoring of the electronic lock and improves the overall reliability of the lock.

[0075] Example 2

[0076] Based on the structural scheme of Embodiment 1, this embodiment provides a more preferred scheme, specifically as follows: the first position sensor 6 is a first contact sensor, and the second position sensor 7 is a second contact sensor; contact sensors have the characteristics of simple structure, rapid response, low cost, and accurate sensing, and can reliably realize the position monitoring function. Of course, proximity sensors (such as Hall sensors, optical sensors, etc.) can also be used, and no special limitation is made here.

[0077] Reference Figure 4 , Figure 5 , Figure 12 , Figure 13When the stop mechanism 5 is in the released position 5b, it contacts the first contact sensor and forms a position sensing engagement. When the stop mechanism 5 is in the stopped position 5a, it separates from the first contact sensor. At this time, the first contact sensor is triggered and sends an electrical signal to the control circuit board 2. The control circuit board 2 determines that the stop mechanism 5 is in the released state based on this signal, allowing the rotary switch 3 to extend and retract. When the stop mechanism 5 is in the stopped position 5a, the moving part of the stop mechanism 5 disengages from the sensing end of the first contact sensor, and the two are separated. Therefore, the first contact sensor is not triggered and does not send another electrical signal to the control circuit board 2 (or stops sending trigger signals). The control circuit board 2 determines that the stop mechanism 5 is in the stopped state, and the extension and retraction of the rotary switch 3 is restricted.

[0078] Reference Figure 6 , Figure 7 When the rotary switch 3 is in the retracted position 3b, it contacts the second contact sensor and forms a position sensing engagement. When the rotary switch 3 is in the extended position 3a, it separates from the second contact sensor. After being triggered, the second contact sensor sends an electrical signal to the control circuit board 2. The control circuit board 2 determines that the rotary switch 3 is in the retracted state, at which point the cabinet door is usually in a locked or locked state. When the rotary switch 3 is in the extended position 3a, the end or a specific protruding part of the rotary switch 3 separates from the sensing end of the second contact sensor. The second contact sensor stops sending trigger signals (or sends another signal), and the control circuit board 2 determines that the rotary switch 3 is in the extended state, at which point the cabinet door is usually in an unlocked or locked state.

[0079] Optionally, refer to Figure 6 , Figure 7 The rotary switch 3 has a protruding drive block 321 on its side wall. The lock housing 1 contains a movable feedback component 8, which has a feedback end and a drive end. The drive end of the feedback component 8 forms a contactable transmission connection with the drive block 321, and the feedback end of the feedback component 8 forms a position sensing connection with the second position sensor 7. When the rotary switch 3 extends or retracts, the drive block 321 moves accordingly, contacting the drive end of the feedback component 8 and causing the feedback component 8 to move. The feedback end of the feedback component 8 forms a position sensing connection with the second position sensor 7. The movement of the feedback component 8 changes the relative position between the feedback end and the second position sensor 7, thereby causing the second position sensor 7 to generate a corresponding sensing signal.

[0080] The specific structure of the preferred feedback component 8 is as follows: (Refer to...) Figure 6 , Figure 7 The feedback component 8 is a rocker, with its middle part rotatably connected to the lock housing 1 via a rotating shaft. A reset torsion spring 84 is provided between the rocker and the lock housing 1. When the lock housing 1 enters the retracted position 3b of the rotary switch 3, the drive block 321 contacts the drive end of the feedback component 8 and drives the feedback component 8 closer to the second position sensor 7, so that the second position sensor 7 senses the position change of the feedback end of the feedback component 8. When the lock housing 1 exits the retracted position 3b of the rotary switch 3, the drive block 321 moves away from the drive end of the feedback component 8, and under the action of the reset torsion spring 84, the feedback component 8 moves away from the second position sensor 7, so that the second position sensor 7 senses the position change of the feedback end of the feedback component 8. The feedback component 8 is specifically a rocker structure, which realizes the transmission of force through the lever principle and achieves automatic reset in conjunction with the reset torsion spring 84. It has the characteristics of high transmission efficiency, sensitive response, and strong structural stability. It can accurately convert the linear extension and retraction motion of the rotary switch 3 into the rotational motion of the rocker, thereby enabling the second position sensor 7 to reliably monitor the position status of the lock body component 4, further improving the accuracy and reliability of the dual position monitoring system.

[0081] Example 3

[0082] Reference Figure 4 , Figure 5 , Figure 11 , Figure 12 , Figure 13 In this embodiment, the stop mechanism 5 includes a drive device 51, a linkage block 52, and a stop execution block 53. The linkage block 52 and the stop execution block 53 can be an integral part or separate parts connected by assembly. The three form an organically linked transmission system.

[0083] The drive device 51 is fixedly installed in the lock housing 1, and the drive device 51 has an eccentric output shaft 511; the axis of the eccentric output shaft 511 is not coaxial with the rotation center of the drive device 51. When the drive device 51 is working, the eccentric output shaft 511 will make eccentric circular motion, thereby converting part of the rotational motion force into linear driving power.

[0084] The linkage block 52 is connected between the eccentric output shaft 511 and the stop actuator block 53. Under the drive of the eccentric output shaft 511, the linkage block 52 has a rising position state 52a and a falling position state 52b.

[0085] When the linkage block 52 is in the raised position 52a, the linkage block 52 contacts the first position sensor 6 and forms a position sensing engagement. The first position sensor 6 then sends a "release" signal to the control circuit board 2. At the same time, the stop execution block 53 rises with the linkage block 52, and the position of the stop execution block 53 is offset from that of the rotary switch 3, thereby releasing the constraint on the rotary switch 3 so that the rotary switch 3 can perform telescopic movement.

[0086] When the linkage block 52 is in the lowered position 52b, the linkage block 52 separates from the first position sensor 6, and the first position sensor 6 sends a "stop" signal to the control circuit board 2. At this time, the stop execution block 53 abuts against the rotary switch 3 and forms a position interference engagement, entering the movement trajectory range of the rotary switch 3, and restricting the extension and retraction movement of the rotary switch 3 by means of mechanical blocking.

[0087] Optionally, a stop block 322 protrudes from the side wall of the rotary switch 3. The stop block 322 can be offset from or abut against the stop actuator block 53. The setting of the stop block 322 makes the cooperation between the rotary switch 3 and the stop actuator block 53 clearer, avoiding the problem of unreliable stopping caused by the irregular structure of the rotary switch 3. At the same time, the stop block 322 can be designed with a specific shape and size according to the actual force requirements, enhancing its structural strength and extending its service life. This cooperation structure further improves the working stability of the stopping mechanism 5, echoes the status monitoring of the first position sensor 6, and jointly ensures the security of the electronic lock in the stopped state.

[0088] Example 4

[0089] Reference Figure 8 In this embodiment, the rotary switch 3 includes an operating section 31 and a transmission section 32. The operating section 31 is located at the front end of the transmission section 32 and is typically exposed outside the lock housing 1 for user convenience. For example, the user can control the state of the lock by rotating or pushing / pulling the operating section 31. The transmission section 32 is movably disposed within the lock housing 1 and plays a crucial role in transmitting the action of the operating section 31 to subsequent components. Its movement is adapted to the overall operating mechanism of the lock.

[0090] The lock body component 4 includes a guide section 41 and a latch section 42. The latch section 42 is fixedly installed to the rear end of the guide section 41. The latch section 42 is the key part for locking the door cabinet. When the latch section 42 rotates, the locking and unlocking of the door cabinet can be completed. A telescopic drive elastic element 9 is provided between the front end of the guide section 41 and the rear end of the transmission section 32. The telescopic drive elastic element 9 acts on the transmission section 32 so that the rotating switch 3 always has a tendency to move away from the lock body component 4.

[0091] When no external force is applied to the operating section 31 and the stop mechanism 5 is in the released position 5b, the rotary switch 3 will naturally tend to extend to the extended position 3a under the elastic force of the telescopic drive elastic member 9. When the user applies an external force to push the operating section 31, causing the rotary switch 3 to move towards the lock body member 4 against the elastic force of the telescopic drive elastic member 9, the rotary switch 3 enters the retracted position 3b. When the user removes the external force and the stop mechanism 5 is in the released position 5b, the rotary switch 3 can automatically return to a state with a tendency to move away from the lock body member 4 under the action of the telescopic drive elastic member 9, and may then return to the extended position 3a.

[0092] By dividing the work between the operation section 31 and the transmission section 32, the operation becomes more convenient for users while ensuring the stability of the internal transmission. On the other hand, the setting of the telescopic drive elastic element 9 realizes the automatic reset trend of the rotary switch 3, making the operation of the lock more in line with the user's habits. It also provides a stable driving force basis for the transmission cooperation between the rotary switch 3 and the lock body component 4, ensuring the continuity and reliability of the transmission between the two.

[0093] It is worth mentioning that when the rotary switch 3 is in the extended position 3a relative to the lock housing 1, the transmission section 32 can transmit torsional force to the lock body component 4 through the telescopic drive elastic element 9, so that the lock body component 4 and the rotary switch 3 form a transmission engagement. Based on the torsional transmission design in the extended position 3a, and cleverly combined with the elastic characteristics of the telescopic drive elastic element 9, the extension tendency of the rotary switch 3 in the non-operating state is ensured, while efficient force transmission is achieved in the operating state, demonstrating the rationality of the collaborative work between the components.

[0094] Reference Figures 9-10 In some preferred embodiments of this utility model, the lock housing 1 is provided with a through hole 13, and the transmission section 32 is movably inserted in the through hole 13. The through hole 13 provides the transmission section 32 with basic movement space and radial constraint.

[0095] Linear telescopic guide structure: The inner wall of the through hole 13 is provided with guide ribs 131, and the transmission section 32 is provided with linear guide grooves 323 distributed along the telescopic direction of the rotary switch 3. The guide ribs 131 are slidably fitted in the linear guide grooves 323. When the rotary switch 3 performs telescopic movement, the guide ribs 131 slide axially in the linear guide grooves 323, which can effectively limit the rotational freedom of the transmission section 32, ensuring that the rotary switch 3 can only perform telescopic movement along the axial direction without unnecessary rotation, thus ensuring the stability and accuracy of the telescopic action.

[0096] Rotary motion release structure: The transmission section 32 is also provided with a rotating groove 324, which is connected to the end of the straight guide groove 323. When the rotary switch 3 is in the extended position 3a, the guide rib 131 is located in the rotating groove 324 and can move along the rotating groove 324. Since the rotating groove 324 releases the circumferential constraint on the guide rib 131, the guide rib 131 can move circumferentially along the rotating groove 324, thereby giving the transmission section 32 rotational freedom.

[0097] To further optimize the transmission smoothness between the rotary switch 3 and the lock body component 4, especially the force transmission efficiency during the switching process from telescopic motion to rotary motion, in some preferred embodiments of this utility model: the rear end of the transmission section 32 has a first arc-shaped guide end face 325, and the front end of the guide section 41 is provided with a second arc-shaped guide end face 411. The curvature radii of the two arc-shaped guide end faces are matched to form a complementary curved surface mating structure.

[0098] Retracted fit: When the rotary switch 3 is in the retracted position 3b, the first arc-shaped guide end face 325 is at least partially always in contact with the second arc-shaped guide end face 411; the advantage is that it ensures the stability of the lock body component 4 in the retracted position and avoids shaking caused by gaps.

[0099] Release mechanism in rotation state: When the rotary switch 3 is in the extended position 3a, the positions of the first arc-shaped guide end face 325 and the second arc-shaped guide end face 411 are offset so that the rotary switch 3 can rotate.

[0100] Reference Figure 8 By adopting the above-mentioned cooperation between the first arc-shaped guide end face 325 and the second arc-shaped guide end face 411, the problem of smooth switching between linear motion and rotational motion is solved. This ensures smoothness during the extension and retraction process and provides a reliable structural foundation for the rotational motion. It enables the two motion modes (extension / rotation) of the rotary switch 3 to switch in an orderly manner without interfering with each other, further improving the mechanical transmission reliability of the electronic lock.

[0101] It is worth noting that the other technical solutions of this utility model are all existing technologies, and therefore will not be described in detail.

[0102] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the concept of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
