[0012] The present application provides a lock device. Figure 1 illustrates a specific embodiment of a lock device 100 including a lock housing 10, a lock cylinder assembly 30 disposed within the lock housing 10, and a thumbturn assembly 50 transmission-coupled with the lock cylinder assembly 30.

[0013] The present application also provides a locking device. FIGS. 2 and 3 show a specific embodiment of a locking device 200 including a first object 210, a second object 220, and a locking device 100. Here, the locking device 100 is attached to the first object 210 and interengages with the second object 220, thereby locking the second objects 210 and 220 together or apart. Specifically, the locking device 100 has an unlocked state and a locked state. In the locked state, as shown in FIG. 3 , the first object 210 to which the locking device 100 is attached is locked to the second object 220. For example, when the locking device 100 is attached to a door / window, the door / window can be locked to a door frame / window sill to create a private space. As another example, when the locking device 100 is attached to a cabinet door, the cabinet door can be locked to the cabinet body to create a secure space for storing valuables, confidential documents, etc. In the unlocked state, as shown in FIG. 2, the first object 210 to which the locking device 100 is attached can be opened to the second object 220; for example, a door or window can be opened for ventilation, or a drawer can be opened to access documents.

[0014] 4 to 6. The lock cylinder assembly 30 is a basic part of the lock device 100, and can be combined with a key (not shown) to lock and unlock the lock device 100. In this embodiment, the lock cylinder assembly 30 includes a lock plug 32, SThe lock device 100 includes a cylinder tailpiece 34 and a locking member 36. Specifically, the lock plug 32 has a generally cylindrical structure and is rotatably disposed within the lock housing 10. A keyhole 321 is provided in the center of the lock plug 32 for inserting a suitable key. After inserting a key into the keyhole 321, the lock plug 32 can be driven and rotated by applying force. The cylinder tailpiece 34 is disposed at the axially inner end of the lock plug 32. Driving the lock plug 32 drives the locking member 36 to rotate to a locked or unlocked position, thereby driving the connected lock body, latch bolt, etc. to expand and contract, thereby locking and unlocking the lock device 100. The locking member 36 may be separately molded and then connected to the cylinder tailpiece 34, or it may be integrated with the cylinder tailpiece 34. In the illustrated embodiment, the locking member 36 has a locking hook structure. According to different orientations of the locking hook structure of the locking member 36, the locking member 36 can have different rotation directions when performing a locking action.

[0015] Also, please refer to FIG. 7. The first clutch mechanism 40 is disposed between the lock plug 32 and the cylinder tailpiece 34, and includes a first drive portion 42 and a first clutch portion 44 that interact with each other. In this embodiment, the first drive portion 42 is disposed at the side end of the lock plug 32 facing the cylinder tailpiece 34, and the first clutch portion 44 is disposed at the side end of the cylinder tailpiece 34 facing the lock plug 32. The first drive portion 42 includes opposing first and second drive surfaces C1 and D1. An arc-shaped groove 441 is formed in the first clutch portion 44, and a first clutch surface C2 and a second clutch surface D2 are formed on both circumferential sides of the arc-shaped groove 441 in the first clutch portion 44. Preferably, first drive member 42 is a drive pin that extends into arcuate groove 441 of first clutch member 44, with first drive surface C1 corresponding to first clutch face C2 and second drive surface D1 corresponding to second clutch face D2. First drive member 42 can rotate within arcuate groove 441 relative to first clutch member 44, so that first drive surface C1 and first clutch face C2 come into contact with or separate from each other, and second drive surface D1 and second clutch face D2 come into contact with or separate from each other.

[0016] When the first drive surface C1 of the first drive member 42 abuts the first clutch surface C2, the first clutch mechanism 40 is in a first engaged state, allowing the lock plug 32 to drive the cylinder tailpiece 34 to rotate in a first direction (e.g., counterclockwise). When the second drive surface D1 abuts the second clutch surface D2, the first clutch mechanism 40 is in a second engaged state, allowing the lock plug 32 to drive the cylinder tailpiece 34 to rotate in a second direction (e.g., clockwise). When the first drive surface C1 disengages from the first clutch surface C2 and the second drive surface D1 disengages from the second clutch surface D2, the first clutch mechanism 40 is in a disengaged state, allowing the cylinder tailpiece 34 to remain stationary as the lock plug 32 rotates, i.e., the lock plug 32 spins freely. Preferably, the central angle corresponding to the distance between the first clutch surface C2 and the second clutch surface D2 (i.e., the arc-shaped groove 441) is approximately 180 degrees. In the present application, the first clutch mechanism 40 is provided between the lock plug 32 and the cylinder tailpiece 34, so that the lock plug 32 and the cylinder tailpiece 34 have two states: disengaged and engaged. Only in the engaged state can the lock plug 32 drive and rotate the cylinder tailpiece 34 to lock or unlock.

[0017] In some embodiments, the first drive portion 42 may be molded separately and then assembled to the lock plug 32, or may be integrally molded with the lock plug 32. The first clutch portion 44 may be molded separately and then assembled to the cylinder tailpiece 34, or may be integrally molded with the cylinder tailpiece 34.

[0018] Also see Figure 8. The thumbturn assembly 50 described above is used for keyless locking of the lock device 100, i.e., the lock device 100 can be locked without the lock plug 32 being inserted into the key. The thumbturn assembly 50 includes an operating member 52 and a reset member 54. The operating member 52 may be a knob or the like, and the reset member 54 may be a coil spring, torsion spring, or the like.

[0019] A second clutch mechanism 60 is disposed between the operating member 52 and the cylinder tailpiece 34. The second clutch mechanism 60 includes a second drive unit 62 and a second clutch unit 64 that interact with each other. The second drive unit 62 is connected to the thumbturn assembly 50, and the second clutch unit 64 is connected to the cylinder tailpiece 34. The second clutch mechanism 60 allows the thumbturn assembly 50 and the cylinder tailpiece 34 to have two states: disengaged and engaged. In the engaged state, rotation of the operating member 52 drives and rotates the cylinder tailpiece 34 and the locking member 36, thereby locking the vehicle. In this manner, when using the lock device 100 of the present application, the lock can be locked by driving and rotating the lock plug 32, cylinder tailpiece 34, and locking member 36 with a key, or by driving and locking the cylinder tailpiece 34 and locking member 36 with the operating member 52. This allows keyless locking and improves operational convenience.

[0020] The second drive portion 62 is an arc-shaped block having a third drive surface A1 and a fourth drive surface B1 formed on both circumferential sides thereof. The second clutch portion 64 is also an arc-shaped block having a third clutch surface A2 and a fourth clutch surface B2 formed on both circumferential sides thereof. The second drive portion 62 and the second clutch portion 64 are arranged coaxially and have the same size; that is, both are arranged on the same ring. The third drive surface A1 and the third clutch surface A2 face each other, and the fourth drive surface B1 and the fourth clutch surface B2 face each other. When the operating member 52 rotates, the third drive surface A1 and the third clutch surface A2 can be brought into contact with or separated from each other, and the fourth drive surface B1 and the fourth clutch surface B2 can be brought into contact with or separated from each other. Preferably, the central angle corresponding to the circumferential lengths of the second drive portion 62 and the second clutch portion 64 is approximately 90 degrees.

[0021] One end of the returning member 54 is connected to the operating member 52, and the other end is connected to a fixed member such as the lock housing 10. When the operating member 52 is rotated relative to the lock housing 10 by the action of an external force, the returning member 54 is compressed or stretched. When the external force acting on the operating member 52 is canceled, the returning member 54 recovers from its deformation, driving the operating member 52 to rotate in the reverse direction and return to its original position. Preferably, positioning portions 59 are disposed on the operating member 52 and the lock housing 10, respectively, and the two positioning portions 59 abut or are inserted into both ends of the returning member 54. When the operating member 52 rotates relative to the lock housing 10, the end of the returning member 54 abutting against the operating member 52 rotates in conjunction with the rotation of the lock housing 10, causing further deformation and generating a restoring elastic force that returns the operating member 52 in the reverse direction.

[0022] The lock plug 32 is preferably mounted within the operating member 52, and the two are preferably frictionally fitted together, so that the lock plug 32 is fixed within the operating member 52 and can rotate synchronously therewith when not subjected to external force, but can rotate relative to the lock plug 32 when subjected to external force (such as turning a key). Preferably, a lock tube 56 for installing the lock plug 32 is provided at the center of the interior of the operating member 52, and a through-hole 529 is provided on the outer end surface of the operating member 52 at a position corresponding to the lock tube 56, thereby exposing the keyhole 321 of the lock plug 32. A sliding locking pin may be arranged on the lock plug 32 and / or the lock tube 56, with the length arrangement of the locking pin corresponding to the shape of the notch portion of the key, and the lock plug 32 can be rotated relative to the lock tube 56 by inserting the key to slide the locking pin and unlock.

[0023] The operation process of the lock device 100 of the present invention will be described below using an example in which counterclockwise rotation locks and clockwise rotation unlocks.

[0024] In one embodiment, as shown in FIG. 9 , initially, the lock apparatus 100 is in an unlocked state, the first clutch mechanism 40 is in an engaged state, and the second clutch mechanism 60 is in an engaged state. Specifically, the first drive surface C1 of the first drive member 42 abuts the first clutch face C2 of the first clutch component 44. The second drive surface D1 is spaced apart from the second clutch face D2, and the central angle between the two is approximately 180 degrees, i.e., a semicircle. The third drive surface A1 of the second drive member 62 abuts the third clutch face A2 of the second clutch component 64, and the fourth drive surface B1 is spaced apart from the fourth clutch face B2, and the central angle between the two is approximately 180 degrees, i.e., a semicircle.

[0025] When the operating member 52 is rotated to lock the locking mechanism in the unlocked state, as shown in FIG. 9a, a force is applied to rotate the operating member 52 counterclockwise by a certain angle (e.g., 90 degrees), causing the lock plug 32 inside the operating member 52 to rotate synchronously with the operating member 52. Because the third drive surface A1 and the third clutch surface A2 of the second clutch mechanism 60 are in contact with each other, the rotation of the operating member 52 drives the cylinder tailpiece 34 and the locking member 36, which then rotate counterclockwise by a corresponding angle until they reach the locked position. In this case, the locking member 36 is locked to the second object 220, and the locking mechanism 100 enters the locked state. During this process, the operating member 52, lock plug 32, cylinder tailpiece 34, and locking member 36 rotate synchronously, while the first clutch mechanism 40 and the second clutch mechanism 60 all remain engaged. However, the rotation of the operating member 52 compresses or stretches the return member 54, causing elastic deformation.

[0026] After locking the lock device 100 with the operating member 52, when the operating member 52 is released, as shown in FIG. 9b, the return member 54 recovers from its deformation and drives the operating member 52 to rotate in the reverse direction (i.e., clockwise) and return, thereby separating the third drive surface A1 from the third clutch surface A2, and the second clutch mechanism 60 switches to the disengaged state. In this case, the central angle corresponding to the distance between the third drive surface A1 and the third clutch surface A2 is approximately 90 degrees. During the automatic return process of the operating member 52, the lock plug 32 rotates in the reverse direction together with the operating member 52 and returns. While the cylinder tailpiece 34 and the locking member 36 remain stationary, the cylinder tailpiece 34 and the lock plug 32 rotate relative to each other, and the first drive surface C1 separates from the first clutch surface C2. At this time, the central angle corresponding to the distance between the two becomes greater than 90 degrees, and the first clutch mechanism 40 switches to the disengaged state.

[0027] When the lock device 100 needs to be unlocked, 9c As shown in FIG. 9( a ), a key is inserted into the keyhole 321 of the lock plug 32, and the key is first used to rotate the lock plug 32 a first angle (e.g., 90 degrees) in a second direction (i.e., clockwise), causing the second drive surface D1 of the first drive unit 42 to abut against the second clutch surface D2 of the first clutch unit 44, switching the first clutch mechanism 40 to an engaged state. Then, as shown in FIG. 9( c ), the key is subsequently rotated a second angle (e.g., 90 degrees) in the second direction, causing the lock plug 32 to drive the cylinder tailpiece 34 and the locking member 36, which then rotate synchronously to the unlocked position. During this process, the operating member 52 remains stationary, and the cylinder tailpiece 34 and the locking member 36 rotate approximately 90 degrees relative to the operating member 52, returning the third drive surface A1 to a position where it abuts against the third clutch surface A2, and the second clutch mechanism 60 returns to an engaged state.

[0028] After unlocking the lock apparatus 100, the key can be removed. Before removing the key, the key is rotated in a first direction, i.e., counterclockwise, by a certain angle. This angle is the sum of the first angle and the second angle, which is 180 degrees in this embodiment. The lock plug 32 rotates with the key, disengaging the first drive part 42 from the second clutch surface D2. The first drive surface C1 returns to abutting contact with the first clutch surface C2, and the first clutch mechanism 40 returns to the engaged state. During this process, the operating member 52, the cylinder tailpiece 34, and the locking member 36 remain stationary, while the third drive surface A1 remains in abutment with the third clutch surface A2. That is, the second clutch mechanism 60 remains engaged. The lock apparatus 100 as a whole returns to the initial state shown in FIG. 9.

[0029] The lock device 100 can also be locked with a key when it is unlocked. In this case, inserting the key into the keyhole 321 of the lock plug 32 and rotating it counterclockwise causes the first drive surface C1 of the first drive unit 42 to rotate the first clutch surface C2 of the first clutch unit 44, which in turn drives the cylinder tailpiece 34 and the locking member 36 to rotate counterclockwise and reach the locked position. In this process, the operating member 52 remains stationary, while the cylinder tailpiece 34 rotates relative to the operating member 52, disengaging the third drive surface A1 from the third clutch surface A2 and switching the second clutch mechanism 60 to the disengaged state. After locking the lock device 100 with the key, the key can be directly removed, and the first clutch mechanism 40 remains engaged.

[0030] In the case of the lock device 100 of the present application, by slightly adjusting its initial state, it is possible to lock by rotating it clockwise and unlock by rotating it counterclockwise.

[0031] In the unlocked state, as shown in Figure 9e, first clutch mechanism 40 is engaged but is adjusted so that second drive surface D1 of first drive unit 42 abuts against second clutch surface D2 of first clutch unit 44, and second clutch mechanism 60 is engaged but is adjusted so that fourth drive surface B1 of second drive unit 62 abuts against fourth clutch surface B2 of second clutch unit 64. The subsequent locking and unlocking processes are similar to those described above, and as shown in Figure 9f, keyless locking is achieved by the abutment of fourth drive surface B1 and fourth clutch surface B2 of second clutch mechanism 60. When unlocking with a key, the engagement state of first clutch mechanism 40 switches to the abutment of first drive surface C1 and first clutch surface C2, and this process will not be repeated here.

[0032] In this embodiment, the cylinder tailpiece 34 comprises a cylinder tailpiece body 341 and a first transmission member 343. The first transmission member 343 is generally cylindrical, with a first connecting hole 345 and a second connecting hole 347 formed at both ends, respectively. The first connecting hole 345 is used to connect the lock cylinder tailpiece body 341, and the second connecting hole 347 is used to connect the locking member 36. Specifically, one end of the first transmission member 343, where the second connecting hole 347 is provided, extends to the outside of the lock housing 10, and the locking portion 36 is connected to the first transmission member 343. Material 36 is detachably connected to second connecting hole 347 by screws, rivets, etc. One end of cylinder tailpiece body 341 is inserted into first connecting hole 345, and the two may be a clearance fit or an interference fit. In some embodiments, cylinder tailpiece body 341 and first transmission member 343 may be an integral structure.

[0033] A first clutch portion 44 is formed at the other end of the cylinder tailpiece body 341, and the first clutch portion 44 abuts against an end face of the lock plug 32. The second clutch portion 64 is disposed on one end face of the first transmission member 343 facing the lock plug 32, and extends axially outward from the first transmission member 343. In other embodiments, the second clutch portion 64 may be formed separately and then assembled to the first transmission member 343.

[0034] In another embodiment shown in Figures 10 and 10a, the cylinder tailpiece 34 comprises a cylinder tailpiece body 341 and a first transmission member 343 inserted into and connected to the cylinder tailpiece body 341, with the first clutch portion 44 disposed on the cylinder tailpiece body 341 and the second clutch portion 64 disposed on the first transmission member 343. The difference is that one end of the cylinder tailpiece body 341 extends outward after passing through the first transmission member 343 and the lock housing 10, and is connected to the latch bolt, lock device body, etc. via a transmission mechanism.

[0035] In this embodiment, the operating member 52 includes a knob 521 and a second transmission member 523. The knob 521 has a cylindrical structure with one open end and one closed end, and the lock tube 56 and the lock plug 32 are disposed in the center of the interior of the knob 521, and a through hole 529 is provided at the closed end of the knob 521 at the position of the keyhole 321 corresponding to the lock plug 32. A plurality of connecting columns 525 extend from the closed end of the knob 521 toward the open end, and a plurality of fixing holes 527 are provided in the second transmission member 523 corresponding to the connecting columns 525. Fixing members such as screws pass through the fixing holes 527 and then fit into the connecting columns 525. La The second transmission member 523 is threadably fixed to the rotatable knob 521. In some embodiments, the second transmission member 523 and the knob 521 may also be integrally formed.

[0036] In this embodiment, the locking tube 56 is molded separately and then assembled to the knob 521, specifically, assembled in the space surrounded by the connecting columns 525. Preferably, the locking tube 56 has a fitting 58 that protrudes between two adjacent connecting columns 525, so that the locking tube 56 and the knob 521 are restricted in the circumferential direction and can rotate synchronously after assembly. In some embodiments, the locking tube 56 and the knob 521 can also be molded integrally.

[0037] As shown in FIG. 5, the lock housing 10 includes a mounting seat 12 and a sleeve tube 14 extending outward from the center of the mounting seat 12 in a direction away from the operating member 52. The knob 521 is sleeved onto the mounting seat 12, a second transmission member 523 is disposed on the mounting seat 12, a return member 54 is sleeved onto the second transmission member 523, and positioning portions 59 are disposed on the second transmission member 523 and the mounting seat 12. In this embodiment, as shown in FIGS. 4 and 6, a step portion 121 is provided on the inner wall surface of one end of the mounting seat 12 facing the knob 521, which restricts the second transmission member 523 in the axial direction, preventing the second transmission member 523 from separating from the lock housing 10 and further preventing the entire operating member 52 from separating from the lock housing 10. Preferably, a bearing 16 is disposed between the mounting seat 12 and the second transmission member 523 to reduce friction when they rotate relative to each other. Preferably, an anti-wear gasket 18 is disposed between the step 121 of the mounting seat 12 and the second transmission member 523 to further reduce wear.

[0038] The first transmission member 343 is disposed in the sleeve tube 14, with both ends thereof extending outside the sleeve tube 14, and the cylinder tailpiece 34 passes through the second transmission member 523 and is connected to the first transmission member 343. The second transmission member 523 surrounds the corresponding end of the first transmission member 343 and protrudes radially inward to form a second drive portion 62 that is aligned with the second clutch portion 64. In some embodiments, the second drive portion 62 can extend axially outward from the second transmission member 523. The second clutch portion 64 can also extend radially outward from the first transmission member 343. Alternatively, if the second drive portion 62 has all of the second clutch portions 64 extending axially or all of them extending radially and both are located on the same ring, contact and separation can be achieved through relative rotation, and as a result, the second clutch mechanism 60 switches between the two states of separation and engagement.

[0039] Preferably, the sleeve 14 has a thread 19 formed on its periphery so that the lock device 100 can be installed by screwing it onto a first object 210 such as a door or window.

[0040] The lock device 100 of the present application can achieve key locking or keyless locking through the settings of the first clutch mechanism 40 and the second clutch mechanism 60, making it more convenient to use. Furthermore, the second clutch mechanism 60 can be adjusted to lock by rotating counterclockwise or clockwise, allowing the lock device 100 to operate normally without replacing any components, regardless of whether the first object 210 is rotated left or right. Accordingly, the locking member 36 may have two positions. As shown in the figure, the locking member 36 has a hook-shaped structure, and the hook direction can be set to left or right, which can be achieved by flipping the locking member 36 over, thereby enabling two usage modes: left-opening and right-opening. Overall, the structure is simple, operation is convenient, and versatility is good.

[0041] See FIG. 11. In one optional embodiment of the lock device, the lock device 100 may include a lock body 80, which may be driven by, for example, a locking member 36. In this case, the locking member 36 may be a rod-like structure, one end of which is fixedly connected to a rotating second transmission member 523, and the other end of which is connected to the drive connection portion 82 of the lock body 80. The lock device 100 is disposed on the first object 210 and drives the cylinder tailpiece 84 of the lock body 80 to move and lock the lock. In this embodiment, the cylinder tailpiece 84 is called a deadbolt or square bolt, etc., i.e., the cylinder tailpiece 84 does not have an inclined surface for a latch bolt structure. When locking or unlocking a deadbolt lock device, the extension and retraction of the deadbolt must be controlled by operating the control unit of the lock device. In contrast, when using a latch bolt structure, the latch bolt can generally be retracted simply by pressing an object against the inclined surface of the latch bolt perpendicular to the direction of extension of the latch bolt. Therefore, deadbolt structures are more secure than latch bolt structures.

[0042] Referring to Figure 12, in one optional embodiment of the lock device, the lock device 100 includes a lock housing 10, a lock cylinder assembly 30 disposed within the lock housing 10, a thumbturn assembly 50 and a lock body 80 that are electrically connected to the lock cylinder assembly 30, the thumbturn assembly 50 including a first operating member 52 and a second knob 88, the first operating member 52 having the lock cylinder assembly 30 disposed on one side of a first object 110 and the second knob 88 disposed on the other side of the first object 110 via a fixed seat 86. The locking member 36 is a drive rod connected to the lock body 80, the drive rod passing through a drive connection 82 of the lock body 80 and electrically connected to the drive connection 82. In this embodiment, the drive rod 361 has a trapezoidal cross section, and the drive connection portion 82 is formed in a trapezoidal hole that roughly corresponds to this trapezoidal cross section, so that the rotation of the locking member 36 can be transmitted to the lock body 80 by a connection that matches the shape of the drive connection portion 82.

[0043] In this embodiment, the drive connection 82 of the lock body 80 has a different setting. In this setting, the drive connection 82 is rotated 180 degrees, and the locking member 36 and the first transmission member 343 are also rotated 180 degrees. An auxiliary adjustment rod can be added to rotate the first transmission member 343. The adjustment rod has an adjustment end that matches the shape of the transmission member receiving opening of the first transmission member 343 and a thin rod portion. The adjustment end passes through the drive connection 82 of the lock body 80 and can rotate. In this case, the thin rod portion is not mechanically connected to the drive connection 82. The adjustment rod can be adjusted to the desired setting by rotating the first transmission member 343.

[0044] Similar to the above-described embodiment, a lock device having an additional setting can be attached to a first object that opens to the left or right without replacing the lock device. Naturally, in order to clearly distinguish between the two setting states, the first transmission member 343, the drive coupling portion 82, and the locking member 36 can be provided with identification for distinguishing between the two installation states, thereby preventing assembly errors.

[0045] During assembly, the lock housing 10, first transmission member 343, cylinder tailpiece 31, return member 54, second transmission part 523, locking sleeve 32, first operating member 52, etc. are first assembled in order and placed next to the first object 210 to be locked. The lock body 80 is embedded inside the first object 210 to be locked, and the cylinder tailpiece 84 of the lock body 80 is extendable relative to the first object 210. Then, the locking member 36 is inserted and penetrates the drive coupling part 82 of the lock body 80, so that the locking member 36 penetrates the lock body 80 and is transmission-coupled to the first transmission member 343. If the setting state of the first transmission member 343 needs to be adjusted in this step, the first transmission member 343 can be adjusted using the adjustment rod. After the locking member 36 is inserted into a predetermined position, the fixing seat 86 and the second knob 88 can be sequentially attached to the other side of the first object 210. The second knob 88 has a receiving portion for receiving the locking member 36, and the receiving portion is transmission-matched with the locking member 36, so that the second knob 88 can control the locking and unlocking of the lock device. In this embodiment, the cylinder tailpiece of the lock body 80 is a deadbolt.

[0046] The above embodiments merely represent preferred embodiments of the present application, and although the descriptions are relatively specific and detailed, they cannot be understood as limitations of the present application. It should be noted that those skilled in the art can make many modifications and improvements without departing from the concept of the present application, such as combining different features in each embodiment, which are within the scope of protection of the present application.
