Description

Technical Field

[0001] This application belongs to the field of lock technology, specifically relating to a lock body. Background Technology

[0002] In some lock technologies, the lock cylinder is located inside the housing, with a through hole in the housing opposite the cylinder, allowing users to directly insert a key into the lock cylinder's keyhole to unlock it. However, because the keyhole of the lock cylinder is exposed, it increases the risk of the lock being pried open, leading to damage and affecting its normal use. Summary of the Invention

[0003] The purpose of this application is to provide a lock body that can solve the problem that existing locks are easily pried open.

[0004] To solve the above-mentioned technical problems, this application is implemented as follows:

[0005] This application provides a lock body, including: a shell, a blocking member, a lock cylinder, and a limiting mechanism;

[0006] The outer casing has a first through hole on its wall surface, and the lock cylinder is located inside the outer casing and is positioned opposite to the first through hole;

[0007] The shielding component is movably connected to the outer casing and is used to block or expose the first through hole;

[0008] The limiting mechanism includes a limiting member, a detection member, and a first driving assembly, each disposed within the housing. The limiting member is movably connected to the housing and is used to limit or release the blocking member. The first driving assembly is drively connected to the limiting member.

[0009] The outer casing is also provided with a second through hole, the detection element is disposed opposite to the second through hole and is electrically connected to the first drive component.

[0010] In this embodiment, when the detection component cannot detect the corresponding key, the first drive assembly is in its initial state. At this time, the blocking component is positioned opposite the first through hole, thus blocking the lock cylinder. The blocking component is also limited by the limiting component and cannot be opened. When the detection component detects the corresponding key, it sends a control signal. Upon receiving the control signal, the first drive assembly starts and moves the limiting component relative to the outer shell, releasing the limiting effect on the blocking component. This allows the blocking component to move relative to the outer shell, thereby releasing the blockage of the first through hole and exposing the lock cylinder for subsequent operation to unlock the lock body. Based on the above, this embodiment can block the lock cylinder with a blocking component and limit the blocking component to prevent it from being opened, effectively preventing damage to the lock cylinder and providing anti-pry protection for the lock cylinder, ensuring the safety and reliability of the lock body.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0031] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0032] refer to Figures 1 to 10 This application discloses a lock body that can be applied to base stations, cabinets, boxes, etc., and of course, it can also be applied to other scenarios, which are not specifically limited here. The disclosed lock body includes a shell 100, a blocking member 200, a lock cylinder 300, and a limiting mechanism 400.

[0033] The outer casing 100 is the basic mounting component of the lock body, providing a mounting base for the shield 200, lock cylinder 300, limiting mechanism 400, etc. In some embodiments, the outer casing 100 may have an inner cavity, in which the shield 200, lock cylinder 300, and limiting mechanism 400 may be disposed, so that the outer casing 100 can protect the above-mentioned components from damage or interference from the external environment.

[0034] The lock cylinder 300 is the core component of the lock body, used for unlocking or locking the lock body; additionally, the lock cylinder 300 can also cooperate with a key. For example, the lock cylinder 300 may have a lock cylinder hole 320 through which a key can be inserted to unlock or lock the lock body. In some embodiments, the lock cylinder 300 is located inside the outer casing 100.

[0035] Considering that the key needs to cooperate with the lock cylinder 300 during the unlocking process, the lock cylinder 300 needs to be exposed to allow the key to pass through. Therefore, in this embodiment, the wall of the outer casing 100 is provided with a first through hole 110, such as... Figures 1 to 3 As shown, the lock cylinder 300 is positioned opposite the first through hole 110. Thus, when unlocking is required, the key can be engaged with the lock cylinder 300, preventing the outer casing 100 from obstructing the engagement of the key with the lock cylinder 300.

[0036] However, in the non-unlocked state, the presence of the first through hole 110 exposes the lock cylinder 300, which poses a risk of being pried open and also makes it easy for dust, rainwater, etc. to enter the interior of the lock cylinder 300, causing the lock body to rust and affecting the normal unlocking or locking of the lock body.

[0037] Based on the above, a shielding component 200 is added to this embodiment, such as... Figure 1 As shown. The obstruction member 200 is movably connected to the outer casing 100 and is used to block or expose the first through hole 110. When the obstruction member 200 is moved to the position of blocking the first through hole 110, it can block the lock cylinder 300, thereby effectively preventing the lock cylinder 300 from being pried and ensuring the reliability of the lock cylinder 300, and also effectively preventing dust, rainwater, etc. from entering the interior of the lock cylinder 300 and causing the lock body to rust.

[0038] For example, the movable connection between the shielding member 200 and the housing 100 can be movement, rotation, etc., which can be set according to the actual working conditions. In addition, the shielding member 200 can be a plate, or of course a block, etc., and its specific shape is not limited.

[0039] Considering that the obstruction 200 is easily opened and cannot protect the lock cylinder 300, this embodiment of the application adds a limiting mechanism 400, such as... Figures 1 to 3 As shown. The limiting mechanism 400 can limit the obstruction 200 when unlocking is not required, preventing the obstruction 200 from being opened arbitrarily, thus ensuring that the lock cylinder 300 is not compromised and the lock body cannot be pried open. When unlocking is required, the limiting mechanism 400 can be released from limiting the obstruction 200, allowing the obstruction 200 to be opened easily, thus exposing the lock cylinder 300 for convenient unlocking.

[0040] refer to Figure 3 and Figure 4 In some embodiments, the limiting mechanism 400 includes a limiting member 410, a detection member 420, and a first driving assembly 430, which are respectively disposed within the housing 100. The limiting member 410 is movably connected to the housing 100 and is used to limit or release the blocking member 200.

[0041] For example, the movable connection between the limiting member 410 and the housing 100 can be movement or rotation, as long as it can limit or release the blocking member 200, and the specific form is not limited.

[0042] To enable the limiting member 410 to move relative to the housing 100, the first drive assembly 430 is connected to the limiting member 410 in a transmission manner, so as to provide power to the limiting member 410 through the first drive assembly 430 so that the limiting member 410 can move relative to the housing 100.

[0043] For example, the first driving component 430 may have a movable end or a rotating end, and the limiting member 410 may be connected to the movable end or the rotating end to change position under the driving action of the first driving component 430, thereby limiting or releasing the blocking member 200.

[0044] Considering that the detection element 420 requires a special key to be triggered, and the key needs to cooperate with the detection element 420 located inside the housing 100, a second through hole 120 can be provided on the wall of the housing 100, with the detection element 420 positioned opposite to the second through hole 120. Therefore, when it is necessary to unlock the limiting mechanism 400, a special key can be inserted into the second through hole 120 to detect the key via the detection element 420.

[0045] In addition, the detection element 420 is electrically connected to the first drive assembly 430 so that it can send a control signal to the first drive assembly 430 after the detection element 420 detects the corresponding key.

[0046] Specifically, when unlocking is required, a special key can be placed into the second through hole 120. When the detection element 420 detects the key, a control signal is sent. After receiving the control signal, the first drive component 430 performs a corresponding action to drive the limiting element 410 to move relative to the outer shell 100. At the same time, the limiting element 410 moves relative to the blocking element 200, thereby limiting or releasing the blocking element 200.

[0047] Optionally, when the key is inserted into the second through hole 120, the detection element 420 can detect that the key is an unlocking key by mutual induction with the key through a signal of a specific frequency; in addition, when the key is inserted into the second through hole 120, it can also contact the detection element 420 to trigger the detection element 420, thereby determining that the key is an unlocking key.

[0048] It should be noted that the second through hole 120 can be designed as a dedicated through hole, which cooperates with a dedicated key, and only the dedicated key can be inserted into the second through hole 120. For example, the second through hole 120 can be a spiral hole, a bent hole, an irregularly shaped hole, etc. with specific parameters, and the shape of the second through hole 120 is not specifically limited here.

[0049] For example, the key can be an electronic key. When the electronic key moves to the second through hole 120, it can be detected by the detection element 420, and a signal can be transmitted to unlock the limiting mechanism 400. Of course, the key can also be a mechanical key. In this case, the key can have contacts. The contacts contact the detection element 420, triggering the detection element 420, which then sends a control signal to the first drive assembly 430, causing the first drive assembly 430 to move the limiting member 410.

[0050] For example, the detection element 420 can be in the form of a pressure sensor, a photoelectric sensor, a contact switch, a signal receiver, etc., and of course, it can also be in other forms, which are not specifically limited here. When the detection element 420 is a pressure sensor or a photoelectric sensor, after detecting the key, the detection element 420 sends a control signal to the first drive assembly 430, so that the first drive assembly 430 drives the limiting member 410 to move, thereby releasing the limiting member 410 from its limiting effect on the blocking member 200; when the detection element 420 is a contact switch, the key can close the contact switch, connecting the power supply circuit of the first drive assembly 430, thereby driving the limiting member 410 to move, thereby releasing the limiting member 410 from its limiting effect on the blocking member 200.

[0051] Furthermore, when the key is removed, the detection element 420 cannot detect the key and sends a control signal to the first drive assembly 430 again. This causes the first drive assembly 430 to move the limiting element 410, thereby limiting the blocking element 200 again. Alternatively, the limiting mechanism 400 may include a reset element connected to the limiting element 410 and the housing 100. This reset element allows the limiting element 410 to return to its original position after the first drive assembly 430 loses power, thus limiting the blocking element 200 again. For example, the reset element could be a spring, rubber band, etc.

[0052] Additionally, the power for the blocking member 200 to move relative to the outer casing 100 to block the first through hole 110 can come from the user directly applying force to the blocking member 200. Alternatively, a return member connected between the blocking member 200 and the outer casing 100 can be provided to drive the blocking member 200 back to its original position. For example, the return member can be a spring, rubber band, etc.

[0053] In this embodiment, when the detection element 420 cannot detect the corresponding key, the first drive assembly 430 is in its initial state. At this time, the blocking element 200 is located opposite to the first through hole 110, thereby blocking the lock cylinder 300. The blocking element 200 is limited by the limiting element 410 and cannot be opened. When the detection element 420 detects the corresponding key, it sends a control signal. After receiving the control signal, the first drive assembly 430 starts and drives the limiting element 410 to move relative to the outer shell 100, thereby releasing the limiting effect on the blocking element 200. This allows the blocking element 200 to move relative to the outer shell 100, thereby releasing the blocking of the first through hole 110 and exposing the lock cylinder 300, so that the lock body can be unlocked by subsequent operation of the lock cylinder 300. Based on the above, it can be seen that the lock cylinder 300 can be blocked by the blocking member 200 and the blocking member 410 can limit the blocking member 200 to prevent it from being opened, thereby effectively preventing the lock cylinder 300 from being damaged, playing the role of anti-prying of the lock cylinder 300, and ensuring the safety and reliability of the lock body.

[0054] In this embodiment, the limiting member 410 is movable relative to the outer shell 100 so as to change the relative position between the limiting member 410 and the blocking member 200 when the limiting member 410 is movable relative to the outer shell 100, thereby limiting or releasing the blocking member 200.

[0055] In some embodiments, the limiting member 410 is slidably connected to the second through hole 120 along the centerline direction of the second through hole 120, and has a first position and a second position. In the first position, the limiting member 410 is released from the blocking member 200 to limit the blocking member 200. In the second position, the limiting member 410 is separated from the blocking member 200 to limit the blocking member 200 in contact. Based on this configuration, the limiting member 410 can move between the first position and the second position to limit or release the blocking member 200. This ensures that the blocking member 200 will not be opened when unlocking is not required, thus protecting the lock cylinder 300 from damage. It also facilitates the opening of the blocking member 200 when unlocking is required, allowing subsequent operation of the lock cylinder 300 to unlock it.

[0056] In other embodiments, the limiting member 410 can be rotatably connected to the housing 100 and can switch between a first position and a second position by rotation. In the first position, the limiting member 410 can limit the blocking member 200 to ensure that the blocking member 200 cannot be opened, and in the second position, the limiting member 410 can be separated from the blocking member 200 so that the blocking member 200 can be opened.

[0057] For example, the limiting member 410 and the housing 100 can be connected by a shaft to enable the limiting member 410 to rotate relative to the housing 100.

[0058] Optionally, the limiting member 410 may include a limiting part and an unlocking part that are connected or integrally disposed. The limiting part may be located inside the housing 100 and is used to limit the movement by contacting the blocking member 200 or to release the limitation by separating from the blocking member 200. The unlocking part may be located outside the housing 100 and is used to cooperate with a key so that the limiting mechanism 400 can be opened by the key.

[0059] In some embodiments, the detection element 420 may be disposed on the limiting element 410 so that the limiting element 410 can support the detection element 420. Of course, the detection element 420 may also be disposed directly on the inner wall of the housing 100, which can also achieve the installation of the detection element 420.

[0060] Optionally, the limiting member 410 may be provided with a jack 411 for inserting a key, such as Figure 5 As shown, the insertion hole 411 is disposed opposite to the second through hole (120). For example, the insertion hole 411 can be disposed in the unlocking part, and of course, the insertion hole 411 can also pass through the unlocking part and extend to the limiting part.

[0061] The detection element 420 can be disposed on the inner wall of the socket 411 for detecting the key. Based on this, when unlocking is required, the key can be inserted into the socket 411. At this time, the detection element 420 is triggered, detecting that the key has been inserted into the socket 411. Then, a control signal is sent to the first drive assembly 430 or the power supply circuit of the first drive assembly 430 is turned on, so that the first drive assembly 430 drives the limiting member 410 to move, thereby releasing the limiting effect on the blocking member 200. This makes it easier to open the blocking member 200 and expose the lock cylinder 300, so as to facilitate subsequent operation of the lock cylinder 300 to achieve unlocking.

[0062] refer to Figure 4In some embodiments, the first driving assembly 430 may include a first rotating member 431, a bushing 432, and a connecting shaft 433. The output shaft of the first rotating member 431 is connected to the bushing 432, the connecting shaft 433 is connected to the limiting member 410, and the bushing 432 is threadedly connected to the connecting shaft 433. Based on this configuration, the first rotating member 431 can drive the bushing 432 to rotate. As the bushing 432 rotates, it drives the connecting shaft 433 to move axially. Ultimately, the connecting shaft 433 drives the limiting member 410 to move, thereby changing the position of the limiting member 410 relative to the blocking member 200, thus limiting or releasing the blocking member 200.

[0063] In other embodiments, the first drive assembly 430 may separately include a first rotating member 431, the output shaft of which is connected to the limiting member 410 to drive the limiting member 410 to rotate and switch it between a first position and a second position.

[0064] For example, the first rotating member 431 may include a motor or electric motor, and of course, it may also include a speed reducer.

[0065] In other embodiments, the first drive component 430 may also include a telescopic member that drives the limiting member 410 to move so as to switch between a first position and a second position.

[0066] In some embodiments, the shield 200 can be slidably connected within the housing 100 so that one end of the shield 200 can abut against or separate from the limiting member 410. This arrangement improves the smoothness of the shield 200 during sliding.

[0067] For example, a groove 130 may be provided in the area around the first through hole 110 inside the housing 100. The edge of the shield 200 may be slidably connected with the groove 130. On the one hand, this ensures the smooth sliding of the shield 200, and on the other hand, it can limit the shaking of the shield 200 and ensure that the shield 200 will not be pried open.

[0068] Furthermore, the groove 130 may include a straight groove segment and an inclined groove segment, and the edge of the blocking member 200 may be provided with a slider, which can slide in the straight groove segment and the inclined groove segment; in addition, a portion of the outer surface of the blocking member 200 may be provided with a protrusion.

[0069] When the slider slides within the straight groove section, the blocking member 200 moves entirely within the outer casing 100. When the slider slides to the inclined section, the blocking member 200 moves forward and gradually towards the first through hole 110. When the slider reaches the end of the inclined groove, the blocking member 200 is precisely positioned opposite the first through hole 110, and the protrusion on the outer surface of the blocking member 200 is embedded in the first through hole 110, with the outer surface of the protrusion flush with the outer surface of the outer casing 100, thus completely sealing the first through hole 110. Based on this configuration, there is no point of force for prying open between the blocking member 200 and the outer casing 100, thereby achieving an anti-pry effect.

[0070] In other embodiments, the shield 200 can be rotatably connected to the housing 100, and one end of the shield 200 can abut against or separate from the limiting member 410.

[0071] Specifically, an arc-shaped groove may be provided inside the outer casing 100 around the first through hole 110, and the edge of the blocking member 200 may be slidably connected to the arc-shaped groove. This ensures the smooth sliding of the blocking member 200 and limits its shaking, preventing it from being pried open. Alternatively, the blocking member 200 may be connected to a rotary drive member, allowing it to rotate and change position.

[0072] Furthermore, the arc-shaped groove can be an arc-shaped spiral groove, and the edge of the shield 200 can be provided with a slider, which slides in the arc-shaped spiral groove; in addition, a portion of the outer surface of the shield 200 can be provided with a convex bulge.

[0073] As the slider slides along the arc-shaped spiral groove, the blocking member 200 rotates horizontally and moves vertically. When the slider reaches the end of the arc-shaped spiral groove, the blocking member 200 is precisely positioned opposite the first through hole 110, and the protrusion on the outer surface of the blocking member 200 is embedded in the first through hole 110, with the outer surface of the protrusion flush with the outer surface of the outer shell 100, thus completely sealing the first through hole 110. Therefore, there is no point of force for prying open between the blocking member 200 and the outer shell 100, thereby achieving an anti-pry effect.

[0074] In some embodiments, the lock body may further include a bolt and a clutch mechanism 500, wherein the bolt is slidably connected to the housing 100 and can extend out of the housing 100 or retract into the housing 100, the lock cylinder 300 is rotatably connected to the housing 100, and the clutch mechanism 500 is disposed inside the housing 100 for drivingly connecting the lock cylinder 300 and the bolt, or drivingly separating the lock cylinder 300 and the bolt.

[0075] In this embodiment, the clutch mechanism 500 has a transmission connection state and a transmission disengagement state. In the transmission connection state, the lock cylinder 300 drives the bolt to slide relative to the outer shell 100 through the clutch mechanism 500. In the transmission disengagement state, the lock cylinder 300 rotates relative to the outer shell 100, while the bolt remains stationary relative to the outer shell 100. Based on this configuration, when the clutch mechanism 500 is in the transmission disengagement state, the lock cylinder 300 cannot drive the bolt to slide through the clutch mechanism 500, thus preventing the lock body from unlocking. Therefore, even if the lock cylinder 300 is rotated in this state, it will only spin freely and cannot drive the bolt to slide. Consequently, there is no fulcrum to force the bolt to slide and unlock the lock body, preventing the lock body from being pried open and ensuring the safety and reliability of the lock body.

[0076] refer to Figure 6 In some embodiments, the clutch mechanism 500 may include an actuating element 510 and a second drive assembly 520. The lock cylinder 300 has a receiving space 310, and the second drive assembly 520 is disposed within the receiving space 310, allowing the lock cylinder 300 to install and protect the second drive assembly 520. The actuating element 510 is located outside the receiving space and is either drive-connected to or drive-separated from the second drive assembly 520. The actuating element 510 may also contact or separate from the bolt. It should be noted that the actuating element 510 and the bolt may be in direct or indirect contact.

[0077] Based on the above configuration, when the second drive assembly 520 is connected to the actuating member 510, the second drive assembly 520 can drive the actuating member 510 to move, thereby causing the actuating member 510 to contact the locking tongue, which in turn causes the locking tongue to move relative to the housing 100, retracting the locking tongue into the housing 100 and unlocking the device. Alternatively, the second drive assembly 520 can also cause the actuating member 510 to separate from the locking tongue. In this case, the locking tongue can return to its original position and extend outside the housing 100, locking the device. It should be noted that the principle of the locking tongue's return can be found in relevant technologies and will not be elaborated upon here.

[0078] Of course, the second drive assembly 520 can also be disengaged from the actuating member 510, so that even if the lock cylinder 300 is rotated, the lock tongue cannot be retracted through the lock cylinder 300.

[0079] refer to Figure 6 and Figure 7In some embodiments, the second drive assembly 520 may include a second rotating member 521, an eccentric member 522, and a transmission member 523. The actuating member 510 has a mounting cavity 511, and both the eccentric member 522 and the transmission member 523 are located within the mounting cavity 511. The transmission member 523 is situated between the outer periphery of the eccentric member 522 and the side wall of the mounting cavity 511. The second rotating member 521 is drively connected to the eccentric member 522. Based on this configuration, the second rotating member 521 can drive the eccentric member 522 to rotate forward (e.g., counterclockwise). When the eccentric member 522 rotates forward, it exerts a squeezing effect on the transmission member 523, which in turn squeezes the actuating member 510. This causes the actuating member 510 to rotate with the eccentric member 522 and the transmission member 523, and the actuating member 510 actuates the latch, causing the latch to slide synchronously, retracting into the outer casing 100 and unlocking the lock body.

[0080] Conversely, when the second rotating member 521 rotates in the opposite direction (e.g., clockwise), it drives the eccentric member 522 to rotate in the opposite direction. When the eccentric member 522 rotates in the opposite direction, it releases the squeezing effect on the transmission member 523. At this time, the transmission member 523 disengages from the actuating member 510 and cannot drive the actuating member 510 to rotate in the opposite direction. Therefore, it is impossible to move the lock tongue by actuating member 510 to unlock the lock body.

[0081] It should be noted that the rotation angles for both the forward and reverse rotations can be set, such as from 10° to 60°. Furthermore, the principle behind the latch extending beyond the outer casing 100 can be found in relevant technologies and will not be elaborated upon here.

[0082] refer to Figure 7 and Figure 8 The side wall of the mounting cavity 511 may be provided with a first arc-shaped groove 5111, and the outer periphery of the eccentric member 522 may be provided with a second arc-shaped groove 5221. The transmission member 523 is located between the first arc-shaped groove 5111 and the second arc-shaped groove 5221. Based on this configuration, the first arc-shaped groove 5111 and the second arc-shaped groove 5221 can form a space to accommodate the transmission member 523. When the eccentric member 522 rotates in the forward direction, the transmission member 523 is squeezed by the side wall of the second arc-shaped groove 5221, and the transmission member 523 squeezes the side wall of the first arc-shaped groove 5111. Thus, the transmission member 523 drives the actuating member 510 to rotate, and the actuating member 510 actuates the latch to make the latch slide. When the eccentric member 522 rotates in the reverse direction, the side wall of the second arc-shaped groove 5221 releases the squeezing effect on the transmission member 523, and the transmission member 523 disengages from the first arc-shaped groove 5111. At this time, the transmission member 523 can return to its original position and cannot drive the actuating member 510 to rotate, so that the actuating member 510 cannot actuate the latch to make the latch move, and thus cannot unlock the lock body.

[0083] For example, the transmission component 523 can be a sphere, or of course, a cylinder; the specific form is not limited.

[0084] In some embodiments, the first rotating member 431 can drive the eccentric member 522 to rotate in the forward direction but cannot drive the eccentric member 522 to rotate in the reverse direction. In this case, an additional return member is required to return the eccentric member 522 to its original position.

[0085] Specifically, the lock body may also include an elastic element (not shown in the figure) that elastically connects the eccentric element 522 and the lock cylinder 300. Thus, when the first rotating element 431 stops working, the elastic element applies an elastic force to the eccentric element 522, causing the eccentric element 522 to move in the opposite direction and return to its original position. For example, the elastic element can be a spring, such as a torsion spring, or a rubber strip.

[0086] After the eccentric member 522 releases its squeezing effect on the transmission member 523, the transmission member 523 can return to its original position and disengage from the actuating member 510. The transmission member 523 can return to its original position under gravity, or an additional return member can be added to drive the transmission member 523 back to its original position; this return member can be an elastic structural component.

[0087] To enable the clutch mechanism 500 to automatically switch between a transmission engagement state and a transmission disengagement state, the lock body may further include a trigger 600, which is electrically connected to the clutch mechanism 500. Additionally, the lock cylinder may have a lock cylinder hole 320 for inserting a key, and the trigger 600 is disposed in the lock cylinder hole 320 for contact with the key and being triggered. Exemplarily, the trigger 600 is electrically connected to the second drive assembly 520.

[0088] Based on the above configuration, after the key is inserted into the lock cylinder hole 320, the key contacts the trigger 600, triggering the trigger 600 and sending a control signal to the clutch mechanism 500 to engage or disengage the clutch mechanism. Specifically, after the key is inserted into the lock cylinder hole 320, the key contacts the trigger 600, triggering the trigger 600 and sending a control signal to the second drive assembly 520, activating the second drive assembly 520. The second drive assembly 520 then drives the bolt to slide via the actuating member 510 to achieve unlocking.

[0089] Based on the above settings, when the key is not used for unlocking, the trigger 600 will not be triggered, and therefore will not send an unlocking control signal to the clutch mechanism 500. As a result, the clutch mechanism 500 will not drive the bolt to slide, thus ensuring that the lock body is in the locked state.

[0090] When using a key to unlock, the key contacts the trigger 600, which triggers the trigger 600. The trigger 600 sends an unlocking control signal to the clutch mechanism 500, causing the clutch mechanism 500 to switch to the transmission connection state, thereby driving the lock tongue to slide and unlock.

[0091] It should be noted that after the key engages with the lock cylinder 300, the key can contact the trigger 600, triggering the trigger 600 and thus activating the power supply circuit of the second drive assembly 520. When the key is removed, the trigger 600 cannot be activated, the power supply circuit of the second drive assembly 520 is open, causing the second drive assembly 520 to disengage from the actuating member 510, thus preventing the movement of the lock cylinder 300 from being transmitted to the bolt and causing the bolt to move.

[0092] For example, when the second drive assembly 520 is de-energized, the power to separate the transmission between the second drive assembly 520 and the actuating member 510 can come from gravity, or an additional return member can be added to achieve the transmission separation between the second drive assembly 520 and the actuating member 510. The return member can be a spring, rubber band, etc.

[0093] For example, the trigger 600 can be a contact switch, but it can also be other components, which are not specifically limited here.

[0094] refer to Figures 6 to 9 In some embodiments, the lock body may further include a transmission connector 700, which is slidably connected within the housing 100 and connected to the latch. The transmission connector 700 has a transmission cavity 710, and an actuating member 510 is rotatably disposed within the transmission cavity 710, with its outer periphery abutting or separating from the side wall of the transmission cavity 710. Based on this configuration, when the second drive assembly 520 drives the actuating member 510 to rotate through the transmission connection, the outer periphery of the actuating member 510 will press against the side wall of the transmission cavity 710, causing the transmission connector 700 to slide relative to the housing 100 and driving the latch to slide, thereby causing the latch to retract into the housing 100.

[0095] When the second drive assembly 520 drives the actuating member 510 to rotate, causing the outer periphery of the actuating member 510 to separate from the side wall of the transmission cavity 710, the driving action on the transmission connector 700 is released. At this time, the locking tongue can extend relative to the outer shell 100.

[0096] Of course, when the second drive assembly 520 is disengaged from the actuating member 510, the actuating member 510 can return to its original position under the return action of the transmission connector 700 and the locking tongue.

[0097] For example, the outer periphery of the toggle member 510 may be provided with an outward protrusion structure 510, which abuts against or separates from the side wall of the transmission cavity 710.

[0098] In summary, the lock body in this embodiment can have anti-pry function, ensuring that the lock body can be used normally without being damaged.
