Description

Technical Field

[0001] This application relates to the field of lock technology, and more specifically, to a lock cylinder and a padlock. Background Technology

[0002] Electric locks have the advantages of high efficiency, security, convenience and intelligence. Electric locks mainly achieve the unlocking process through electrical unlocking mechanisms. However, in the current lock bodies that use electrical unlocking, the lock body cannot be opened normally when the electrical unlocking fails. Utility Model Content

[0003] This application provides a lock cylinder and padlock that can be unlocked in an emergency when electrical unlocking fails.

[0004] This application is achieved through the following technical solution:

[0005] In a first aspect, embodiments of this application provide a lock cylinder, including a locking pin sleeve, a locking pin, a first unlocking shaft, an electrical unlocking mechanism, and a mechanical unlocking mechanism. The locking pin is movably disposed in the locking pin sleeve and has a locked position and an unlocked position. The first unlocking shaft is rotatably disposed in the locking pin sleeve and is drively connected to the locking pin. The electrical unlocking mechanism is configured to drive the first unlocking shaft to rotate, thereby switching the locking pin between the locked and unlocked positions. Forward rotation of the first unlocking shaft can switch the locking pin from the locked position to the unlocked position, and reverse rotation of the first unlocking shaft can switch the locking pin from the unlocked position to the locked position. The mechanical unlocking mechanism is configured to drive the first unlocking shaft to rotate forward, thereby switching the locking pin from the locked position to the unlocked position.

[0006] In the above embodiments, by setting a first unlocking shaft, an electrical unlocking mechanism, and a mechanical unlocking mechanism, and enabling both the electrical and mechanical unlocking mechanisms to drive the first unlocking shaft to rotate in the forward direction, thereby switching the lock pin from the locked position to the unlocked position, normal unlocking can be achieved through the electrical unlocking mechanism, and emergency unlocking of the lock cylinder can be achieved when the electrical unlocking mechanism malfunctions.

[0007] In some embodiments, the mechanical unlocking mechanism includes a second unlocking shaft for cooperating with an unlocking tool, the second unlocking shaft being rotatably disposed on a locking pin sleeve, and the second unlocking shaft being configured to drive the first unlocking shaft to rotate in the forward direction.

[0008] In the above embodiments, by setting a second unlocking shaft and a second unlocking shaft that cooperates with the unlocking tool, when the electrical unlocking mechanism fails and emergency unlocking is required, the second unlocking shaft can be driven to rotate by the unlocking tool, thereby driving the first unlocking shaft to rotate in the forward direction, so as to realize the emergency unlocking function.

[0009] In some embodiments, the second unlocking shaft has a first position and a second position, and the second unlocking shaft is configured to drive the first unlocking shaft to rotate in the forward direction during the rotation from the first position to the second position; the lock cylinder also includes a locking component disposed on the lock pin sleeve, and the locking component is configured to prevent the second unlocking shaft located in the second position from rotating to the first position, so as to prevent the first unlocking shaft from rotating in the reverse direction.

[0010] In the above embodiments, after the lock cylinder is unlocked in an emergency, the lock pin is kept in the unlocked position and cannot be returned to the locked position, thereby causing the lock cylinder to fail. With this setting, the battery cell fails after an emergency unlock and cannot be used again, which can effectively improve the security of the lock cylinder.

[0011] In some embodiments, the second unlocking shaft is provided with a limiting groove, and the locking assembly includes a limiting pin and an elastic element. The limiting pin is movably disposed in the locking sleeve; the elastic element is disposed between the limiting pin and the locking sleeve, and the elastic element is configured to drive the limiting pin to insert into the limiting groove when the second unlocking shaft is in the second position. Through the specific configuration of the locking assembly, the locking assembly can lock the lock cylinder in the unlocked state after an emergency unlocking of the lock cylinder, thereby improving the security of the lock cylinder.

[0012] In some embodiments, the first unlocking shaft is provided with a first toothed portion, and the second unlocking shaft is provided with a second toothed portion. During the rotation of the second unlocking shaft from the first position to the second position, the second toothed portion engages with the first toothed portion to drive the first unlocking shaft to rotate forward. When the second unlocking shaft is in the first position and the first unlocking shaft is rotating forward, the first toothed portion and the second toothed portion disengage. The first toothed portion and the second toothed portion engage with each other to achieve rotational engagement between the first and second unlocking shafts, thereby enabling the second unlocking shaft to drive the first unlocking shaft to rotate forward during its rotation from the first position to the second position. When the lock cylinder is unlocked normally via the electrical unlocking mechanism, it will not affect the mechanical unlocking mechanism, thus avoiding activation of the locking components and lock cylinder failure.

[0013] In some embodiments, the rotation axis of the first unlocking shaft is perpendicular to the rotation axis of the second unlocking shaft. This perpendicularity allows the rotation directions of the first and second unlocking shafts to differ, thereby reducing the space occupied by the lock cylinder.

[0014] In some embodiments, the electrical unlocking mechanism includes a drive assembly and an energy storage element. The energy storage element connects the drive assembly and a first unlocking shaft. The drive assembly is configured to drive the first unlocking shaft to rotate forward and backward via the energy storage element. When the locking pin in the unlocked position is restricted, the drive assembly operates to allow the energy storage element to accumulate elastic force. This elastic force is used to drive the first unlocking shaft to rotate backward after the locking pin is released. The energy storage element enables the lock cylinder to unlock and reset, allowing for repeated use of the lock cylinder.

[0015] In some embodiments, the rotation axis of the first unlocking shaft is perpendicular to the movement direction of the locking pin. This arrangement allows the first unlocking shaft and the locking pin to be better positioned within the locking pin sleeve, thereby reducing the space occupied by the lock cylinder.

[0016] In some embodiments, the first unlocking shaft is provided with a locking protrusion, which is eccentrically positioned relative to the first unlocking shaft. The locking pin is provided with a locking groove, and the locking protrusion engages with the locking groove, so that the rotation of the first unlocking shaft drives the locking pin to move. The locking protrusion and the locking groove, which are eccentrically positioned relative to the first unlocking shaft, cooperate to drive the locking pin to move when the first unlocking shaft rotates.

[0017] Secondly, embodiments of this application provide a padlock, including a lock body, a lock beam, and a lock cylinder according to any embodiment of the first aspect. The lock beam is movably disposed within the lock body; the lock cylinder is at least partially disposed within the lock body, and a locking pin sleeve is connected to the lock body. The locking pin is configured to lock the lock beam in the locked position and unlock the lock beam in the unlocked position. A padlock equipped with a lock cylinder according to any embodiment of the first aspect enables automatic unlocking of the padlock via a mechanical unlocking mechanism when electrical unlocking fails.

[0018] In some embodiments, the mechanical unlocking mechanism includes a second unlocking shaft for cooperating with an unlocking tool. The second unlocking shaft is rotatably disposed on a lock pin sleeve and configured to drive a first unlocking shaft to rotate in the forward direction. The lock body has an unlocking window for exposing the second unlocking shaft. The padlock also includes a blocking member that detachably blocks the unlocking window. The blocking member blocks the unlocking window, and in the event of an emergency unlocking, the blocking member is removed, allowing the unlocking tool to cooperate with the second unlocking shaft for emergency unlocking.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly 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.

[0034] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0035] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0036] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0037] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0038] Please see Figures 1-4 , Figure 1 A schematic diagram of the structure of a padlock provided in some embodiments of this application (the locking pin is in the locked position); Figure 2 A schematic diagram of the padlock structure provided for some embodiments of this application (lock pin in the unlocked position); Figure 3 This is a diagram showing the positional relationship between the lock beam 200 and the lock cylinder 300 in some embodiments of this application (with the lock pin in the locked position); Figure 4 This diagram illustrates the positional relationship between the lock beam 200 and the lock cylinder 300 in some embodiments of this application (with the locking pin in the unlocked position). Embodiments of this application provide a padlock, including a lock body 100, a lock beam 200, and a lock cylinder 300. The lock cylinder 300 may include a locking pin 20. The lock beam 200 is movably disposed within the lock body 100. The lock cylinder 300 is at least partially disposed within the lock body 100. The locking pin 20 is configured to lock the lock beam 200 in the locked position and unlock the lock beam 200 in the unlocked position.

[0039] The lock cylinder 300 can be entirely located within the lock body 100, or it can be partially located within the lock body 100.

[0040] The locking beam 200 is movably disposed within the lock body 100. When the locking beam 200 moves relative to the lock body 100, it enables the padlock to be locked and unlocked. When the padlock is in the unlocked state, the locking beam 200 may remain partially within the lock body 100, or the locking beam 200 may be completely separated from the lock body 100.

[0041] The locking pin 20 and the locking beam 200 cooperate to achieve the locking and unlocking of the padlock. When the locking pin 20 is in the locked position, the locking pin 20 and the locking beam 200 are relatively fixed, and the locking beam 200 is fixed relative to the lock body 100 to achieve the locking function of the padlock. When the locking pin 20 is in the unlocked position, the locking beam 200 can move relative to the lock body 100 to achieve the unlocking function of the padlock. In some examples, the locking beam 200 may be connected to a spring member, which is located between the locking beam 200 and the lock body 100. When the padlock is in the locked state, the spring member is in a compressed state. When the padlock switches from the locked state to the unlocked state, the locking pin 20 moves to the unlocked position, and the locking beam 200 moves relative to the lock body 100 under the action of the spring member to achieve unlocking.

[0042] The specific structure of the lock cylinder 300 is described in detail below with reference to the attached diagram.

[0043] Please see Figures 5-7 , Figure 5 This is a schematic diagram of the structure of the lock cylinder 300 provided in some embodiments of this application; Figure 6 A diagram showing the positional relationship between the first unlocking pivot 30, the second unlocking pivot 501, and the unlocking component 60 provided in some embodiments of this application (the second unlocking pivot 501 is located in the first position); Figure 7 This diagram illustrates the positional relationship between the first unlocking shaft 30, the second unlocking shaft 501, and the unlocking component 60, as provided in some embodiments of this application (the second unlocking shaft 501 is located in the second position). Embodiments of this application provide a lock cylinder 300, including a locking pin sleeve 10, a locking pin 20, a first unlocking shaft 30, an electrical unlocking mechanism 40, and a mechanical unlocking mechanism 50. The locking pin 20 is movably disposed on the locking pin sleeve 10 and has a locked position and an unlocked position. The first unlocking shaft 30 is rotatably disposed on the locking pin sleeve 10 and is drively connected to the locking pin 20. The electrical unlocking mechanism 40 is configured to drive the first unlocking shaft 30 to rotate, thereby switching the locking pin 20 between the locked and unlocked positions. Forward rotation of the first unlocking shaft 30 can switch the locking pin 20 from the locked position to the unlocked position, and reverse rotation of the first unlocking shaft 30 can switch the locking pin 20 from the unlocked position to the locked position. The mechanical unlocking mechanism 50 is configured to drive the first unlocking shaft 30 to rotate in the forward direction to switch the locking pin 20 from the locked position to the unlocked position.

[0044] The locking pin 20 is movable relative to the locking pin sleeve 10. Depending on the position of the locking pin 20, two positions can be designated as the locked position and the unlocked position. Taking the locking pin 20 and the locking beam 200 as an example, when the locking pin 20 is in the locked position, it locks the locking beam 200, preventing relative movement between the locking beam 200 and the lock body 100, thus achieving the locking effect of the lock body 100. When the locking pin 20 is in the unlocked position, the locking beam 200 is movable relative to the locking pin 20, allowing relative movement between the locking beam 200 and the lock body 100, thereby achieving the unlocking effect of the lock body 100.

[0045] A spring can be installed between the locking pin 20 and the locking pin sleeve 10. When the locking pin 20 is in the unlocked position, the spring is in a compressed state. In the application scenario where the lock cylinder 300 is used for a padlock, when the lock beam 200 of the padlock switches from the unlocked state to the locked state, the locking pin 20 can move towards the lock beam 200 under the action of the elastic element.

[0046] The locking pin sleeve 10 may consist only of metallic materials, such as stainless steel, or only of non-metallic materials, such as plastic, or a combination of both. In specific applications, the locking pin sleeve 10 is installed within the lock body 100 and fixed relative to it. When the lock cylinder 300 is used with a padlock, the locking pin sleeve 10 is connected to the lock body 100.

[0047] The first unlocking shaft 30 is connected to the locking pin 20 via a transmission connection, meaning that the first unlocking shaft 30, during rotation, can drive the locking pin 20 to move between the locked and unlocked positions. In some examples, the first unlocking shaft 30 and the locking pin 20 may have mutually engaging toothed portions, which, through the engagement of these toothed portions, allow the first unlocking shaft 30 to drive the locking pin 20 to move during rotation. Alternatively, the first unlocking shaft 30 and the locking pin 20 may employ mutually engaging limiting portions, such as a groove on one and a protrusion on the other, which restrict the relative position of the first unlocking shaft 30 and the locking pin 20, thereby enabling the first unlocking shaft 30 to drive the locking pin 20 to move during rotation.

[0048] The electrical unlocking mechanism 40 enables relative movement of the locking pin 20 between the locked and unlocked positions via an electrical structure. The electrical unlocking mechanism 40 can be used for fingerprint unlocking, magnetic unlocking, image unlocking, etc. The electrical unlocking mechanism 40 has the advantages of being difficult to crack by force, high security, intelligence, and convenience. The electrical unlocking mechanism 40 drives the first unlocking shaft 30 to rotate, thereby causing the locking pin 20 to switch between the locked and unlocked positions.

[0049] For ease of explanation, the direction of rotation in which the first unlocking shaft 30 drives the locking pin 20 from the locked position to the unlocked position is defined as the forward rotation direction, and the direction of rotation in which the first unlocking shaft 30 drives the locking pin 20 from the unlocked position to the locked position is defined as the reverse rotation direction. The electrical unlocking mechanism 40 can drive the first unlocking shaft 30 to rotate in both the forward and reverse directions.

[0050] The mechanical unlocking mechanism 50 can drive the first unlocking shaft 30 to rotate forward, thereby switching the locking pin 20 from the locked position to the unlocked position. The mechanical unlocking mechanism 50 can be configured to drive the first unlocking shaft 30 to rotate in the reverse direction, or it can be configured not to drive the first unlocking shaft 30 to rotate in the reverse direction. The mechanical unlocking mechanism 50 can achieve forward rotation of the first unlocking shaft 30 by incorporating a rotating component that rotates in conjunction with the first unlocking shaft 30. Alternatively, the mechanical unlocking mechanism 50 can achieve forward rotation of the first unlocking shaft 30 by incorporating a moving component that engages with the first unlocking shaft 30. For example, the moving component can be a rack and pinion, and the first unlocking shaft 30 can be a gear; the rack's movement in one direction drives the first unlocking shaft 30 to rotate forward.

[0051] In the above embodiments, by setting a first unlocking shaft 30, an electrical unlocking mechanism 40, and a mechanical unlocking mechanism 50, and enabling both the electrical unlocking mechanism 40 and the mechanical unlocking mechanism 50 to drive the first unlocking shaft 30 to rotate in the forward direction, thereby switching the lock pin 20 from the locked position to the unlocked position, normal unlocking can be achieved through the electrical unlocking mechanism 40. Furthermore, in the event of an abnormality in the electrical unlocking mechanism 40, an emergency unlocking function for the lock cylinder 300 can be achieved without forcibly damaging the lock.

[0052] In some embodiments, see still Figure 6 and Figure 7 The mechanical unlocking mechanism 50 includes a second unlocking shaft 501 for cooperating with an unlocking tool. The second unlocking shaft 501 is rotatably disposed on the locking pin sleeve 10 and is configured to drive the first unlocking shaft 30 to rotate in the forward direction.

[0053] The unlocking tool can be a key or any other tool that can drive the second unlocking shaft 501 to rotate. The unlocking tool and the second unlocking shaft 501 work together. The unlocking tool can drive the second unlocking shaft 501 to rotate, which in turn drives the first unlocking shaft 30 to rotate in the forward direction, thus completing the unlocking action.

[0054] The axes of the first unlocking shaft 30 and the second unlocking shaft 501 can be parallel or non-parallel. The first unlocking shaft 30 and the second unlocking shaft 501 can be respectively provided with mutually cooperating toothed portions to enable the second unlocking shaft 501 to drive the first unlocking shaft 30 to rotate in the forward direction.

[0055] The second unlocking shaft 501 can be configured to drive the first unlocking shaft 30 to rotate in the opposite direction, for example, through gear engagement. Alternatively, it can be configured not to drive the first unlocking shaft 30 to rotate in the opposite direction.

[0056] It can be configured such that the first unlocking shaft 30 can drive the second unlocking shaft 501 to move in both the forward and reverse rotation processes, or it can be configured such that it cannot drive the second unlocking shaft 501 to move.

[0057] In the above embodiment, by setting a second unlocking shaft 501 and a second unlocking shaft 501 that cooperates with the unlocking tool, when the electrical unlocking mechanism 40 fails and emergency unlocking is required, the second unlocking shaft 501 can be driven to rotate by the unlocking tool, thereby driving the first unlocking shaft 30 to rotate in the forward direction, so as to realize the emergency unlocking function.

[0058] In some embodiments, see still Figure 6 and Figure 7The second unlocking shaft 501 has a first position and a second position. The second unlocking shaft 501 is configured to drive the first unlocking shaft 30 to rotate forward during the process of rotating from the first position to the second position. The lock cylinder 300 also includes a locking component 60, which is disposed on the lock pin sleeve 10. The locking component 60 is configured to prevent the second unlocking shaft 501 located in the second position from rotating to the first position, so as to prevent the first unlocking shaft 30 from rotating in the reverse direction.

[0059] The locking component 60 prevents the second unlocking shaft 501, located in the second position, from rotating toward the first position. At this time, the second unlocking shaft 501 can be set to continue rotating in the direction of rotation from the first position toward the second position, or it can be set to not be able to continue rotating in the direction of rotation from the first position toward the second position.

[0060] The locking component 60 prevents the second unlocking shaft 501, which is located in the second position, from rotating to the first position, so as to prevent the first unlocking shaft 30 from rotating in the opposite direction. This can be achieved by setting a limiting groove 5012 on the second unlocking shaft 501 and setting a limiting pin 601. When the second unlocking shaft 501 is not located in the second position, the limiting pin 601 is located outside the limiting groove 5012. The limiting pin 601 can be controlled by other components to determine whether it can be inserted into the limiting groove 5012. For example, it can be driven by other driving components to move the limiting pin 601 into the limiting groove 5012 when the second unlocking shaft 501 is in the second position. Alternatively, it can be achieved by setting a wall on the second unlocking shaft 501. For example, if a limiting groove 5012 is set on the wall of the second unlocking shaft 501, when the second unlocking shaft 501 is not in the second position, the limiting pin 601 abuts against the wall of the second unlocking shaft 501, at which time the second unlocking shaft 501 can rotate. When the second unlocking shaft 501 is in the second position, the limiting pin 601 faces the limiting groove 5012 and is inserted into the limiting groove 5012 under the action of external force to prevent the second unlocking shaft 501 from rotating from the second position to the first position.

[0061] In the above embodiment, after the lock cylinder 300 is unlocked in an emergency, the locking pin 20 is kept in the unlocked position and cannot return to the locked position, thereby causing the lock cylinder 300 to fail. With this setting, the lock cylinder 300 fails after an emergency unlock and cannot be used again, which can effectively improve the security of the lock cylinder 300.

[0062] In some embodiments, see still Figure 6 and Figure 7 And further reading Figure 8 , Figure 8This is a schematic diagram of the structure of a locking component 60 provided in some embodiments of this application. The second unlocking pivot 501 is provided with a limiting groove 5012. The locking component 60 includes a limiting pin 601 and an elastic member 602. The limiting pin 601 is movably disposed on the locking sleeve 10; the elastic member 602 is disposed between the limiting pin 601 and the locking sleeve 10, and is configured to drive the limiting pin 601 to insert into the limiting groove 5012 when the second unlocking pivot 501 is in the second position.

[0063] When the second unlocking shaft 501 is not in the second position, the elastic element 602 is compressed and positioned between the limiting pin 601 and the locking pin sleeve 10. At this time, the limiting pin 601 abuts against the area of ​​the second unlocking shaft 501 that is not in the limiting groove 5012. When the second unlocking shaft 501 rotates to the second position, the limiting pin 601 faces the limiting groove 5012. At this time, driven by the elastic element 602, the limiting pin 601 is inserted into the limiting groove 5012 to prevent the second unlocking shaft 501 in the second position from rotating to the first position.

[0064] In the above embodiments, by specifically configuring the locking component 60, the locking component 60 can lock the lock cylinder 300 in the unlocked state after the lock cylinder 300 is unlocked in an emergency, thereby improving the security of the lock cylinder 300.

[0065] In some embodiments, please refer back to the reference. Figure 6 and Figure 7 The first unlocking shaft 30 is provided with a first toothed portion 301, and the second unlocking shaft 501 is provided with a second toothed portion 5011. During the process of the second unlocking shaft 501 rotating from the first position to the second position, the second toothed portion 5011 engages with the first toothed portion 301 to drive the first unlocking shaft 30 to rotate in the forward direction. When the second unlocking shaft 501 is in the first position and the first unlocking shaft 30 is rotating in the forward direction, the first toothed portion 301 and the second toothed portion 5011 disengage.

[0066] The first toothed portion 301 and the second toothed portion 5011 may be spaced apart. During the rotation of the second unlocking shaft 501 from the first position to the second position, the second toothed portion 5011 moves closer to the first toothed portion 301 to drive the first unlocking shaft 30 to rotate in the forward direction. When the first unlocking shaft 30 rotates in the forward direction, the first toothed portion 301 moves away from the second toothed portion 5011. At this time, the first unlocking shaft 30 cannot drive the second unlocking shaft 501 to rotate when it rotates in the forward direction. The first toothed portion 301 and the second toothed portion 5011 may mesh with each other. During the rotation of the second unlocking shaft 501 from the first position to the second position, the second unlocking shaft 501 is driven to rotate in the forward direction. When the first unlocking shaft 30 rotates in the forward direction, the meshing first toothed portion 301 and the second toothed portion 5011 disengage, so that the first unlocking shaft 30 cannot drive the second unlocking shaft 501 to rotate when it rotates in the forward direction.

[0067] In the above embodiment, the first toothed portion 301 and the second toothed portion 501 cooperate with each other to achieve rotational engagement between the first unlocking shaft 30 and the second unlocking shaft 501. This allows the second unlocking shaft 501 to rotate from the first position to the second position, thereby driving the first unlocking shaft 30 to rotate in the forward direction. When the lock cylinder 300 is unlocked normally by the electrical unlocking mechanism 40, it will not affect the mechanical unlocking mechanism 50, thus avoiding activation of the locking component 60 and preventing the lock cylinder 300 from failing.

[0068] In some embodiments, the rotation axis of the first unlocking shaft 30 is perpendicular to the rotation axis of the second unlocking shaft 501. The rotation axis of the first unlocking shaft 30 is the axis of the first unlocking shaft 30, and the rotation axis of the second unlocking shaft 501 is the axis of the second unlocking shaft 501. The perpendicularity between the rotation axes of the first unlocking shaft 30 and the second unlocking shaft 501 allows the rotation direction of the first unlocking shaft 30 to be different from that of the second unlocking shaft 501, thereby reducing the space occupied by the lock cylinder 300.

[0069] In other embodiments, the rotation axis of the first unlocking shaft 30 and the rotation axis of the second unlocking shaft 501 may also be parallel to each other.

[0070] In some embodiments, please refer to Figure 9 , Figure 9This is a schematic diagram of the structure of the lock cylinder 300 provided in some other embodiments of this application. The electrical unlocking mechanism 40 includes a drive assembly 401 and an energy storage element 402. The energy storage element 402 is connected to the drive assembly 401 and the first unlocking shaft 30. The drive assembly 401 is configured to drive the first unlocking shaft 30 to rotate in both the forward and reverse directions via the energy storage element 402. When the locking pin 20 in the unlocked position is restricted, the operation of the drive assembly 401 enables the energy storage element 402 to accumulate elastic force. The elastic force is used to drive the first unlocking shaft 30 to rotate in the reverse direction after the locking pin 20 is released.

[0071] The energy storage component 402 can store energy when it is constrained. The energy storage component 402 can be a torsion spring; it can also be a component that stores energy through a gravity energy storage structure. For example, in the energy storage state, the energy storage component 402 can be located in a high position. After the locking pin 20 is released, the first unlocking shaft 30 can be driven to rotate in the opposite direction by the action of gravitational potential energy.

[0072] Taking the drive assembly 401, which includes a motor and an adapter shaft, as an example, the two ends of the energy storage component 402 can be connected to the adapter shaft and the first unlocking shaft 30 respectively. When the electric unlocking mechanism 40 is unlocking, the motor drives the adapter shaft to rotate, and the adapter shaft drives the first unlocking shaft 30 to rotate in the forward direction through the energy storage component 402, thereby causing the locking pin 20 to move from the locked position to the unlocked position. When the motor drives the adapter shaft to rotate in the reverse direction, the shaft drives the first unlocking shaft 30 to rotate in the reverse direction through the energy storage component 402, thereby causing the locking pin 20 to move from the unlocked position to the locked position. In specific application scenarios, such as when the lock cylinder 300 is applied to the lock body 100, after the locking pin 20 moves to the unlock position, the lock beam 200 will limit the locking pin 20 to prevent it from moving from the unlock position to the locked position. At this time, when the motor rotates in the reverse direction, because the locking pin 20 cannot move to the locked position, it will hinder the first unlocking shaft 30 from rotating in the reverse direction. At this time, the adapter shaft will cause the energy storage component 402 to accumulate elastic force. The accumulated elastic force can drive the first unlocking shaft 30 to rotate in the reverse direction again after the locking pin 20 is released from the restriction, thereby realizing the movement of the locking pin 20 from the unlock position to the locked position and completing the locking of the lock cylinder 300.

[0073] In the above embodiments, the energy storage component 402 enables the lock cylinder 300 to be unlocked and reset, thus enabling the lock cylinder 300 to be reused repeatedly.

[0074] In some embodiments, the rotation axis of the first unlocking shaft 30 is perpendicular to the movement direction of the locking pin 20. This arrangement allows the first unlocking shaft 30 and the locking pin 20 to be better positioned within the locking pin sleeve 10, thereby reducing the space occupied by the lock cylinder 300.

[0075] In some embodiments, see still Figure 5The first unlocking shaft 30 is provided with a locking protrusion 302, which is eccentrically positioned with the first unlocking shaft 30. The locking pin 20 is provided with a locking groove 201, and the locking protrusion 302 is engaged with the locking groove 201, so that the rotation of the first unlocking shaft 30 drives the locking pin 20 to move. By cooperating with the locking protrusion 302 and the locking groove 201 eccentrically positioned with the first unlocking shaft 30, the rotation of the first unlocking shaft 30 can drive the locking pin 20 to move.

[0076] In padlocks that include the lock cylinder 300 of any of the above embodiments, please refer to Figure 10 , Figure 10 The following is a schematic diagram of the structure of a padlock provided in some other embodiments of this application.

The lock body 100 is provided with an unlocking window for exposing the second unlocking shaft 501. The padlock also includes a blocking member 1001, which detachably blocks the unlocking window.

[0077] In the above embodiment, the blocking component 1001 blocks the unlocking window. When emergency unlocking is required, the blocking component 1001 is disassembled, and then the unlocking tool is used in conjunction with the second unlocking pivot 501 to achieve emergency unlocking.

[0078] In some embodiments of this application, a padlock is provided, including a lock body 100, a lock beam 200, and a lock cylinder 300.

The first unlocking shaft 30 is rotatably mounted on the locking pin sleeve 10 and is connected to the locking pin 20 via a transmission connection. The electrical unlocking mechanism 40 includes a drive assembly 401 and an energy storage element 402. The energy storage element 402 is connected to the drive assembly 401 and the first unlocking shaft 30. The drive assembly 401 is configured to drive the first unlocking shaft 30 to rotate forward and backward via the energy storage element 402. The forward rotation of the first unlocking shaft 30 can drive the locking pin 20 to switch from the locked position to the unlocked position. The reverse rotation of the first unlocking shaft 30 can drive the locking pin 20 to switch from the unlocked position to the locked position. When the locking pin 20 in the unlocked position is restricted, the operation of the drive assembly 401 can cause the energy storage element 402 to accumulate elastic force. The elastic force is used to drive the first unlocking shaft 30 to rotate in the reverse direction after the locking pin 20 is released from restriction. The mechanical unlocking mechanism 50 includes a second unlocking shaft 501 that cooperates with an unlocking tool. The second unlocking shaft 501 is rotatably disposed on the locking pin sleeve 10.

During the rotation of the second unlocking shaft 501 from the first position to the second position, the second toothed portion 5011 engages with the first toothed portion 301 to drive the first unlocking shaft 30 to rotate in the forward direction. When the second unlocking shaft 501 is in the first position and the first unlocking shaft 30 is rotating in the forward direction, the first toothed portion 301 and the second toothed portion 5011 disengage. The rotation axis of the first unlocking shaft 30 is perpendicular to the rotation axis of the second unlocking shaft 501, and the rotation axis of the first unlocking shaft 30 is perpendicular to the movement direction of the locking pin 20.
