[0038] Reference Figure 1-3 The image shows a first embodiment of the present invention.

[0039] The lock 100 provided in the first embodiment of the present invention includes a face shell 10, a housing 12 fixed inside the face shell 10, a knob 22 rotatably disposed relative to the housing 12, an unlocking component for cooperating with and being driven by a key, and a clutch component 26 and a locking component 32 disposed inside the housing 12.

[0040] See Figure 1 and Figure 2 Both the faceplate 10 and the housing 12 are generally rectangular parallelepipeds open to one side, with one end along its side forming a semicircle, and the housing 12 is nested inside the faceplate 10. The faceplate 10 and the housing 12 have through holes and arc-shaped holes on their opposite sides. The knob 22 is generally annular, and the unlocking component is located at the center of the knob 22. The knob 22 includes a knob lever 222, and the unlocking component includes a drive connector 242. After the knob 22 and the unlocking component are assembled and installed onto the faceplate 10, the knob lever 222 of the knob 22 is inserted into the arc-shaped hole, and the drive connector 242 of the unlocking component is inserted into the through hole.

[0041] See Figure 2 and Figure 3The unlocking assembly includes a lock cylinder 24 and an unlocking drive 28. The lock cylinder 24 has a keyhole on the outer side facing the lock for inserting a matching key to unlock. The lock cylinder 24 has a drive connector 242 on the inner side facing the lock, extending into the faceplate 10 and housing 12. The unlocking drive 28 is engaged with the drive connector 242. The clutch assembly 26 includes a central hole 260 for the unlocking assembly to pass through, a clutch assembly receiving cavity 266 for accommodating the unlocking drive 28, and a clutch drive portion 268 for receiving drives from the main drive assembly and the unlocking assembly. Specifically, the clutch assembly 26 includes a circular plate-shaped body 269, and the central hole 260 is a through hole that extends through the center of the plate-shaped body 269. The clutch drive portion 268 is a fan-shaped plate disposed on the circumferential outer side of the plate-shaped main body 269. A recess is provided axially between the clutch drive portion 268 and the plate-shaped main body 269, facing away from the inner side of the lock and defining the clutch assembly receiving cavity 266. A clutch lever 267 extending towards the inner side of the lock is also provided on the clutch assembly 26. In this embodiment, the recess is formed by the height difference between the plate-shaped main body 269 and the clutch drive portion 268; that is, the surface of the plate-shaped main body 269 facing the inner side of the lock is lower than the surface of the clutch drive portion 268 facing the inner side of the lock. The clutch drive portion 268 has a first drive portion 262 and a second drive portion 264. In this embodiment, the first drive portion 262 and the second drive portion 264 are respectively the truncated edge portions on both sides of the fan-shaped drive clutch portion 268 in the circumferential direction. The first drive unit 262 can be driven by the main drive component to move in a locking direction along a first direction, and the second drive unit 264 can be driven by the unlocking component to move in an unlocking direction.

[0042] The unlocking drive component 28 and the lock cylinder 24 are respectively disposed on both sides of the clutch assembly 26 along the axial direction. The unlocking drive component 28 is anti-rotationally engaged in the positioning groove on the drive connector 242 of the center hole 260 of the clutch assembly 26, where the lock cylinder 24 extends, thereby clamping the clutch assembly 26 together with the lock cylinder 24. The unlocking drive component 28 is generally annular, with its circumferential side protruding radially to form an unlocking lever 282, which is used to drive the second drive part 264 to move in an unlocking direction. In this embodiment, the radially inner side of the unlocking drive component 28 also includes a fixing protrusion protruding radially inward. The fixing protrusion is a pair of opposing square plate-shaped protrusions, which are used to engage in the corresponding radial grooves on the drive connector 242, thereby achieving an anti-rotation connection.

[0043] The knob 22 is also generally annular, and its radially inner side includes an inwardly protruding retaining ring 224. This retaining ring 224 is positioned near the side of the knob 22 facing the inside of the lock, and together with the circumferential sidewall of the knob 22, surrounds and defines a lock cylinder 24 receiving cavity that opens to the outside of the lock. The lock cylinder 24 is disposed in the lock cylinder 24 receiving cavity. The knob lever 222 protrudes from the end face of the knob 22 facing the inside of the lock, and after installation, it extends into the interior of the lock through the arc-shaped hole on the faceplate 10 and the housing 12, and is arranged on one side of the first drive part 262 of the clutch drive part 268, for driving the clutch drive part 268 to move in a direction that forms a deadbolt.

[0044] The locking assembly 32 includes a latch 322 that can extend and retract from the inside of the lock to the outside, and a locking drive block 324 controlled by the clutch assembly 26. In this embodiment, the locking drive block 324 includes a positioning hole 326 thereon, which is formed in a generally "Y" shape. The two branches of the positioning hole 326 are used to hold the clutch lever 267 in place when it moves to the first positioning position or the second positioning position, respectively. Specifically, the outlines of the two branches of the positioning hole 326 are formed to match the cross-sectional shape of the clutch lever 267, which is rectangular in this embodiment. The rectangular outlines of the two branches are inclined at a certain angle to the orientation of the clutch lever 267 when it is in the first positioning position and the second positioning position, respectively, so that when the clutch lever 267 is in the first positioning position and the second positioning position, its outline exactly corresponds to the rectangular cross-sectional shape of the corresponding positioning hole 326, thereby holding it there.

[0045] In addition, the clutch assembly 26 also includes a clutch positioning assembly, which is driven by spring force to hold the clutch assembly 26 in a first positioning position or a second positioning position. The clutch positioning assembly includes a first torsion spring fixing part 122 disposed on the clutch drive part 268, a second torsion spring fixing part 124 disposed on the housing 12, and a torsion spring 35 disposed between the first torsion spring fixing part 122 and the second torsion spring fixing part 124. The relative position of the first torsion spring fixing part 122 and the second torsion spring fixing part 124 is configured such that when the clutch drive part 268 rotates, and the clutch assembly 26 moves relative to the housing 12 to either the first positioning position or the second positioning position, the torsion spring 35 can push the clutch positioning assembly to maintain it in that position. In this embodiment, the first torsion spring fixing part 122 is a fixing post protruding towards the inside of the lock on the clutch drive part 268, and the second torsion spring fixing part 124 is a fixing post protruding towards the inside of the lock inside the housing 12. The torsion spring 35 is a torsion spring with two legs, each connected to the top of a fixed post. The second torsion spring fixing part 124 is approximately positioned centered on the upper part of the housing 12, while the first torsion spring fixing part 122 is positioned near the first drive part 262 of the clutch drive part 268. This arrangement ensures that when the clutch assembly 26 is in the first positioning position, the torsion spring 35 pushes the clutch assembly 26 to maintain it in that position. When the clutch assembly 26 rotates towards the second positioning position under the action of an operating force, overcoming the torsion spring's elasticity, the torsion spring force increases, and its direction changes accordingly due to the change in the relative positions of the two legs. Until the first torsion spring fixing part 122 passes the second torsion spring fixing part 124 (the centered position) and reaches the opposite side of the housing 12, the torsion spring's elasticity begins to decrease, and the pushing direction of the torsion spring 35 continues to change, ultimately becoming a force that pushes the clutch assembly 26 to maintain it in the second positioning position.

[0046] In addition, a main drive clutch positioning assembly is included, which includes a knob lever 222 disposed on the knob 22, a spring retaining post 129 disposed inside the housing 12, and a return spring 37 connecting the two. The return spring 37 is used to provide a constant tension between the knob lever 222 and the spring retaining post, so that the knob 22 can automatically return to the initial position after being turned.

[0047] In use, turning the knob 22 allows for keyless locking. The knob lever 222 rotates the clutch assembly 26 from a first positioning position to a second positioning position. A torsion spring 35 holds the clutch assembly 26 in this position. The clutch lever 267 then actuates the locking drive block 324, extending the latch 322 and completing the locking. After the driving force is released, the return spring 37 returns the knob 22 to its original position. To unlock, inserting the key into the lock cylinder 24 and turning it pushes the unlocking drive component 28 of the lock cylinder 24 from the second positioning position to the first positioning position. The clutch lever 267 then actuates the locking drive block 324, retracting the latch 322 and releasing the lock.

[0048] Figures 5 to 7A lock 200 according to a second embodiment of the present invention is shown. The lock cylinder 124 of this lock includes a lock scale 1242. In this embodiment, the lock scale 1242 is formed as a long, thin plate. It is understood that in other embodiments, the lock scale 1242 may also be formed as a long, rectangular prism or other shapes. One end of the lock scale 1242 is connected to a lock cylinder body 1241 for engaging with a key. The lock cylinder body 1241 includes a lock cylinder and a lock tube. The lock cylinder includes a keyhole for inserting a corresponding key. When the key is inserted into the lock cylinder through the keyhole, the lock cylinder can rotate relative to the lock tube, thereby unlocking the lock. In this embodiment, a clutch assembly 126 is also included, coaxially disposed with the lock cylinder 124. The clutch assembly 126 is generally disc-shaped and includes a strip-shaped central hole and a second drive portion 264 disposed on its outer periphery. The locking lever 1242 passes through the clutch assembly 126 and engages with the first drive portion 262 of the clutch assembly 126, which is formed as a strip-shaped central hole, thereby enabling the clutch assembly 126 to rotate. The clutch assembly 126 also includes a second drive portion 264 disposed circumferentially outward, which partially protrudes radially from the outer periphery of the clutch assembly 126 and forms a drive edge. The lock also includes an active drive assembly 122, which includes an active drive lever 1222 for driving the second drive portion 264 and a lever 1224 for receiving external drive. Specifically, the main body of the active drive assembly 122 is plate-shaped and hinged to an intermediate fixed plate 112, which is fixedly connected to the housing 110. The main body protrudes radially to one side along its pivot axis to form a lever 1224, which extends out of the housing 110 and can be approached and driven from outside the lock. The main body of the active drive assembly 122 also includes an active drive lever 1222, which protrudes radially to the other side along its pivot axis. This allows the active drive lever 1222 to push the second drive portion 264 of the clutch assembly 126 when it pivots, thereby driving the lock scale 1242 to rotate and complete locking. The main body of the active drive assembly 122 also includes a locking groove 1226 and a spring fixing post 1228. The lock includes a return spring 137 for resetting the active drive lever 1222. One end of the return spring 137 is fixed to the spring fixing post 1228, and the other end is fixed to the housing 110.

[0049] In addition, the lock in this embodiment also includes a deadbolt locking device 144. The deadbolt locking device 144 includes a locking seat 1442 fixed relative to the housing 12 and a locking slider 142 movable relative to the locking seat 1442 by external operation. The locking slider 142 can engage or disengage with the clutch assembly 26, thereby locking or releasing the rotation of the clutch assembly 26. Specifically, the locking slider 142 includes a spring pin 1422 retractably disposed toward the locking seat 1442 and a deadbolt locking pin 1424 protruding toward the active drive assembly 122. The locking seat 1442 is provided with two positioning recesses corresponding to the spring pin 1422. Both positioning recesses correspond to the shape of the spring pin 1422. Thus, the locking slider 142 can be moved along the direction of the positioning recesses and positioned at the positions corresponding to the two positioning recesses. In the first recessed position, the anti-locking pin 1424 is separated from the locking groove 1226 on the main body of the active drive component 122, while in the second recessed position, the anti-locking pin 1424 is inserted into the locking groove 1226 and locks the active drive component 122 to prevent it from rotating.

[0050] The lock in this embodiment also includes a lock body 130 connected to and driven by a lock lever 1242. The lock body 130 can be, for example, a deadbolt lock body or a bolt lock body. The lock body 130 can be connected to the inside of the side of the object to be locked (e.g., a door, window), allowing its bolt to extend or retract, thereby locking the lock body to a fixed object (e.g., a door frame, window frame) or unlocking it from the fixed object. In this embodiment, the lock lever passes through the lock body 130 and extends from the other side of the lock body, connecting to a second drive member 1202. The second drive member 1202 can be, for example, a lever accessible and operable from the other side of the object to be locked, allowing direct control of locking or unlocking of the door from the other side of the object.

[0051] Figure 8 and Figure 9An exploded view of a lock according to a third embodiment of the present invention is shown. Unlike the second embodiment, the lock according to the third embodiment includes a semi-circular bolt 532. This bolt 532, driven by a knob, can be rotated out from inside the lock along an arc-shaped trajectory from an outlet 5102, forming a partially annular locking area on the outside of the lock, before re-entering and locking through an inlet 5104. This allows the semi-circular bolt 532 to jointly enclose a locking area with the lock body shell 510 for locking the object to be locked. A back plate 540, together with the front panel 510, encloses the internal parts of the lock. A lever 527 is hingedly mounted on the back plate 540 at the rear of the lock.

[0052] Specifically, while referring to Figures 10a to 11dThe lock according to a third embodiment of the present invention includes a knob 522, a lock cylinder 524, a faceplate 510, and an unlocking drive 528, similar to those in the lock according to the first embodiment of the present invention. The knob 522 is generally annular, and a generally disc-shaped lock cylinder 524 is disposed substantially coaxially with the knob 522 at the center of the annular structure of the knob 522. The knob 522 includes a knob lever 5222 projecting axially. The knob 522 and the lock cylinder 524 are rotatable relative to each other. The lock cylinder 522 includes a lock cylinder housing 5243, which includes a mounting hole 5244 facing the faceplate 510 for fixed connection to the faceplate 510. The mounting hole 5244 may be, for example, a threaded hole for screwing in a screw. The lock cylinder 522 includes a lock cylinder 5247, which has a keyhole 5245 facing outwards for inserting a corresponding key. The end of the lock cylinder 5247 facing inwards also includes a drive connector 5242. When the corresponding key is not inserted into the lock cylinder, the lock cylinder housing 5243 and the lock cylinder 5247 are locked together. When the corresponding key is inserted into the keyhole 5245, the lock cylinder 5247 can rotate relative to the lock cylinder housing 5243. A radially inwardly extending retaining ring 5224 is formed on the side of the knob 522 facing the faceplate 510. After the two components are assembled and fixed to the faceplate 510 via the mounting hole 5244, the knob lever 5222 of the knob 522 is inserted into the arc-shaped groove 5106 extending axially on the faceplate 510, and the drive connector 5242 of the lock cylinder 524 is inserted into the through hole 5108 formed axially in the center of the faceplate 510. Simultaneously, the retaining ring 5224 is clamped between the faceplate 510 and the lock cylinder 524. Preferably, the inner side of the faceplate 510 is also provided with a spring fixing part 5105 for fixing the return spring. The spring (not shown) for providing the return spring force to the knob 522 can be a tension spring, with one end fixed to the spring fixing part 5105 and the other end fixed to the knob lever 5222, thereby allowing the knob to remain in its initial position when no external force is applied.

[0053] After being inserted into the through hole 5108, the drive connector 5242 is sleeved with the clutch assembly 526 and the unlocking drive member 528 on the other side of the housing. The unlocking drive member 528 is disposed between the clutch assembly 526 and the housing 510.

[0054] The clutch assembly 526 includes a central hole 5260 for the unlocking assembly to pass through, drive teeth 5266 for driving the lever 527, a second drive portion for receiving the drive of the unlocking drive member 528, the second drive portion including part A 5264A and part B 5264B, and a first drive portion 5262 for receiving the drive of the knob. The clutch assembly 526 includes a circular plate-shaped body with a through hole disposed in the center of the plate-shaped body. The first drive portion 5262 is a fan-shaped plate disposed on the circumferential outer side of the plate-shaped body. The drive teeth 5266 are disposed on the side of the first drive portion 5262 that is radially opposite to the first drive portion 5262. The drive teeth 5266 are several gears formed radially outward, and these gears are arranged circumferentially on the radially outer side of the plate-shaped body. In this embodiment, the number of teeth is 4. The clutch assembly 526 is further provided with a second driving part, which includes two protrusions extending radially outward from the plate-shaped body towards the unlocking driving member 528, respectively defined as part A 5264A and part B 5264B. Parts A 5264A and B 5264B are arranged opposite each other on both sides of the driving teeth 5266 along the circumference of the plate-shaped body. The first driving part 5262 can be driven by the knob in a first direction to move in a locking direction. Part A 5264A of the second driving part can be driven by the unlocking driving member 528 to move in an unlocking direction. Part B 5264B of the second driving part can be driven by the unlocking driving member 528 in a direction opposite to the unlocking direction to move in a locking direction.

[0055] The unlocking drive member 528 is anti-rotatably engaged with the drive connector 5242, which extends from the lock cylinder 524 into the central hole of the clutch assembly 526. The unlocking drive member 528 is generally annular, with its circumferential side protruding radially outward to form a fan-shaped unlocking lever 5282. The unlocking lever 5282 is used to drive the A portion 5264A or B portion 5264B of the second drive unit to move in the unlocking or anti-locking direction when the lock cylinder 524 is unlocked. In this embodiment, the radially inner side of the unlocking drive member 528 also includes a radially inward protruding fixing protrusion 5286, which is a pair of opposing square plate-shaped protrusions. This fixing protrusion 5286 is used to engage with the corresponding radial groove 5246 on the drive connector 5242, thereby achieving an anti-rotation connection.

[0056] The lever 527 includes a rectangular plate-shaped main body. An end positioning portion 5272, extending through the plate-shaped main body along its thickness direction, is provided at the center of one end of the rectangular plate-shaped main body. This positioning portion 5272 is used to drive the locking tongue 532. A drive gear 5274 is provided at the other end of the rectangular plate-shaped main body along its long side. The central axis of the drive gear 5274 is oriented towards the face shell 510, allowing it to mesh with the drive teeth 5266 of the clutch assembly 526. The locking tongue 532 is generally annular with a notch. A positioning groove 5322 is provided on the side of the locking tongue 532 facing the back plate 540, and the positioning portion 5272 is adapted to engage with the positioning groove 5322. The lever 527 is hinged to the back plate 540, and the axis of its rotation center coincides with the axis of the drive gear 5274, so that the rotation of the lever 527 can drive the lock tongue 532 to rotate through the cooperation of the positioning part 5272 and the positioning groove 5322 of the lock tongue 532. The lock also includes a return torsion spring 535, one side of which is rotatably connected to a fixing pin 5122 fixed to the middle partition 512 of the face shell 510, and the other side is rotatably connected to a lever return pin 5276 on the lever 527, so that the lever 527 can be held between an unlocked position and a locked position by means of the spring force of the return torsion spring 535. In this embodiment, the unlocked position (e.g., Figure 10a , Figure 11a (as shown) to the locked position (e.g.) Figure 10b , Figure 11b As shown in the figure, the dial 527 rotates approximately 90 degrees.

[0057] Therefore, referring to Figures 10a to 11b When locking is performed by rotating the knob 522, the first drive portion 5262 of the clutch assembly 526 is driven to rotate by the knob, which in turn drives the lever 527 to rotate via the drive teeth 5266, thereby causing the locking tongue 532 to rotate and extend. After the lever 527 moves to the locked position, the spring force of the return torsion spring 535 holds the lever 527 there. The knob 522 can return to its initial position under the action of an external torque or an internal return spring force (for example, provided by a spring connected between the faceplate 510 and the knob 522). At this time, the knob lever 5222 of the knob 522 disengages from the first drive portion 5262 of the clutch assembly 526, and the clutch assembly 526 remains in its original position by engaging its drive teeth 5266 with the drive gear 5274 of the lever 527.

[0058] See also Figure 11b and Figure 11dWhen unlocking, the key is inserted, and the lock cylinder 524 is rotated in the first direction D1. The rotation of the lock cylinder 524 is transmitted to the A part 5264A of the second drive unit through the first transmission side 5282A of the unlocking drive member 528, driving the drive gear 5266 to rotate, which in turn drives the drive gear 5274 to rotate. That is, the lock cylinder 524 drives the bolt clutch assembly 526 to rotate, which in turn drives the lever 527 and the bolt 532 to rotate and move them to a locked position (e.g., Figure 11b Move to the unlock position (as shown) Figure 11d (As shown).

[0059] See also Figure 11a and Figure 11c This lock also includes a method of locking / unlocking via a key. Specifically, when the lock is initially in the unlocked state (e.g., ... Figure 11a When the key is inserted into the lock cylinder 524 (as shown), the lock cylinder 524 is rotated in the second direction D2. The rotation of the lock cylinder 524 is transmitted to the B part 5264B of the second drive unit through the second transmission side 5282B of the unlocking drive member 528, driving the drive gear 5266 to rotate, which in turn drives the drive gear 5274 to rotate. That is, the lock cylinder 524 drives the lock tongue clutch assembly 526 to rotate, which in turn drives the lever 527 and the lock tongue 532 to rotate and move from an unlocked position (such as...). Figure 11a Move to the locked position (as shown) Figure 11c (As shown). This configuration is achieved by adaptively setting the angle between the positions of parts A and B of the second drive unit, such that the positions of parts A and B of the second drive unit allow them to be rotated by the unlocking drive member in either the first direction D1 or the second direction D2, and allow the locking tongue to switch between the unlocked and locked states.

[0060] Understandably, the above embodiments all rely on a key corresponding to the lock to unlock it. In other embodiments, other verification mechanisms can also be used, such as magnetic cards, fingerprints, or password unlocking mechanisms. The unlocking mechanism only needs to complete the verification function and ensure the security of the lock. The verification mechanism can directly replace the key receiving part of the lock cylinder, or it can be set up separately and electrically connected to an electrically driven unlocking mechanism. After successful verification, the electrically driven unlocking mechanism unlocks the lock.

[0061] Figure 12 An embodiment of a locking device according to the present invention is shown, wherein a lock according to a first embodiment of the present invention is fixed to an object 101 to be locked, for enabling the locking tongue 322 of the lock to achieve a deadbolt locking connection with another fixed object 102.

[0062] Figure 13An embodiment of another locking device according to the present invention is shown, wherein a lock 200 according to a second embodiment of the present invention is mounted on a lockable object 301, the lock 200 being capable of fixing the lockable object 301 relative to a fixing object 302.

[0063] Compared to traditional locks that use a key to lock the deadbolt, the aforementioned keyless deadbolt locks offer significantly improved efficiency and security. Furthermore, their compact and simple structure, low cost, and ease of maintenance make them more suitable for general applications, such as home security doors, glass sliding doors, and safe doors.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
