Description

Technical Field

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

[0002] Currently, glass door locks on the market generally include a lock hook, a lock tongue box, and a lock tongue. The lock tongue is set inside the lock tongue box, and the lock hook is inserted into the lock tongue box and engages with the lock tongue to lock the glass door. The lock hook is mostly a rigid structure, so when the glass door is shaken by external force, the reaction force generated by one end of the lock hook hitting the lock tongue box will be transmitted to the glass door, which will make the glass door easily damaged. Utility Model Content

[0003] The purpose of this invention is to provide a glass door lock to solve the problems in the prior art, such as the glass door being easily affected by misalignment when closing, the door being locked from the outside causing people inside to be trapped, and the exposed chain being unsightly.

[0004] To achieve the above objectives, embodiments of this application provide a door lock, including: a first latch box assembly and a first lock hook box assembly. The first latch box assembly includes a first latch box, a first latch, and a first latch drive module. The first latch is disposed within the first latch box, and the first latch drive module is installed within the first latch box. The first lock hook box assembly includes a first lock hook box, a first flexible member, a first slider, a first lock hook, a first spring, and a first lock hook drive module. The first slider is movably disposed within the first lock hook box, and the first lock hook drive module is installed within the first lock hook box. The first lock hook drive module is used to drive the first lock hook to extend out of the first lock hook box to engage with the first latch. The first latch drive module is used to drive the first latch to move, thereby separating the first latch from the first lock hook. One end of the first flexible member is connected to the first slider, and the other end is connected to the first lock hook. The first spring is used to drive the first slider to reset.

[0005] In the above technical solution, when the first lock hook drive module is activated, it drives the first lock hook to extend out of the first lock hook box and move towards the first lock tongue box, engaging with the first lock tongue. The first lock hook drives the first flexible component and the first slider to move in the same direction, while the first slider and the first lock hook box compress the first spring. When the first lock tongue drive module is activated, it opens the first lock tongue, releasing the first lock hook and the elastic force of the first spring. Under the elastic force of the first spring, the first slider retracts the first flexible component and the first lock hook into the first lock hook box. The first lock hook drive module enables the flexibly connected first lock hook to smoothly engage with the first lock tongue. In addition, the design of the first slider and the first spring allows the first lock hook to smoothly retract into the first lock hook box. This design achieves smooth and stable locking and unlocking of the door lock. At the same time, through the cooperation of the first flexible component and the spring, the reset action is smooth, which can improve the service life and stability of the door lock and reduce the risk of local damage when the door is misaligned due to external forces.

[0006] In some embodiments, the first flexible element is a chain.

[0007] In the above technical solution, the chain is connected by a vertical pin, and the device inside the first lock hook box can only rotate and move horizontally. This design allows it to extend and retract only in the direction of door lock opening and closing (horizontal direction), avoiding lateral pulling or twisting caused by door misalignment.

[0008] In some embodiments, the first hook drive module includes a first receiving tube, a first pushing tube, and a first locking knob. The first receiving tube is fixed inside the first hook box, and the first slider is movably disposed inside the first receiving tube. The two ends of the first spring abut against the first receiving tube and the first slider, respectively. The first pushing tube is movably sleeved outside the first receiving tube. The first locking knob is rotatably mounted on the first hook box and is connected to the first pushing tube in a transmission manner. Rotating the first locking knob can drive the first pushing tube to move axially relative to the first receiving tube, and the first pushing tube pushes the first hook to extend out of the first hook box.

[0009] In the above technical solution, the rotational movement of the first locking knob is converted into the linear movement of the first ejector tube, causing the first ejector tube, which is sleeved outside the receiving tube, to move axially. When the user rotates the first locking knob, the first ejector tube moves outward along the axis, pushing the first locking hook out of the locking hook box to complete the locking with the first locking tongue. When unlocking, the first locking tongue opens, the first locking hook is released, the elastic force of the first spring pushes the first slider to automatically reset, and the first locking hook retracts into the first locking hook box under the action of the first slider. This design facilitates a relatively stable engagement between the locking tongue and the locking hook.

[0010] In some embodiments, the first lock hook box assembly further includes a first push-out spring disposed inside the first lock hook box, with its two ends abutting against the first lock hook box and the first push-out tube, respectively. The first push-out spring is used to drive the first push-out tube and the first locking knob to reset.

[0011] In the above technical solution, the two ends of the first push-out spring abut against the inner wall of the lock hook box and the push-out tube, respectively. During the locking process, the movement of the first push-out tube causes the first push-out spring to be compressed and store force. After locking is completed, the user releases the first locking knob, thereby releasing the first push-out tube. Under the rebound force provided by the first push-out spring, the first push-out tube will be pulled back into the first lock hook box. At the same time as the first push-out tube resets, it simultaneously drives the first locking knob back to its initial position. This reset method is smooth and reliable, and can improve the synchronicity of the reset of each component, reduce the risk of impact noise during mechanism reset, and improve the smoothness of knob operation.

[0012] In some embodiments, the first latch drive module includes a first unlock knob, a motor module, and a first clutch mechanism. The first unlock knob is rotatably mounted in the first latch box. The motor module and the first clutch mechanism are both disposed in the first latch box. The first unlock knob and the first latch are connected by transmission through the first clutch mechanism. The first clutch mechanism has a disengaged state and an engaged state. The motor module is used to drive the first clutch mechanism to switch from the disengaged state to the engaged state.

[0013] In the above technical solution, the motor module drives the first clutch mechanism to switch to the engaged state, enabling the force of rotating the first unlocking knob to be transmitted to the first locking tongue, thereby ultimately achieving the manual unlocking function. When the motor module is not activated, the first clutch mechanism will be in the disengaged state, causing the transmission between the first unlocking knob and the first locking tongue to be disconnected. At this time, the first unlocking knob cannot drive the locking tongue to move. Thus, by setting the first unlocking knob, the motor module, and the first clutch mechanism, the reliability of the unlocking operation can be enhanced.

[0014] In some embodiments, the first clutch mechanism includes a first clutch disc, a second clutch disc, a first clutch shaft spring, and a first clutch shaft. The first clutch disc is connected to a first unlocking knob, the second clutch disc is connected to a first locking tongue, and the first clutch shaft is mounted on the first clutch disc. The motor module includes a motor and a push plate. The motor drives the push plate to move, and the push plate pushes the first clutch shaft to move, so that the first clutch shaft connects the first clutch disc and the second clutch disc. The first clutch shaft spring is sleeved on the first clutch shaft, and the two ends of the first clutch shaft spring abut against the first clutch shaft and the first clutch disc, respectively.

[0015] In the above technical solution, when the push plate pushes the first clutch shaft fixed on the first clutch disc to move axially and then inserts it into the corresponding slot of the second clutch disc, the two clutch discs achieve mechanical linkage. At this time, rotating the first unlocking knob drives the first clutch disc, which in turn drives the second clutch disc to rotate. The second clutch disc then drives the first locking tongue to move, completing the unlocking action. During the process of being pushed by the push plate, the first clutch shaft spring is compressed. When the push plate returns to its original position, the spring force of the first clutch shaft spring is released, causing the first clutch shaft to disengage from the second clutch disc, thus separating the first and second clutch discs. When the first clutch shaft disengages from the second clutch disc, the two clutch discs are in a separated state. Rotating the first unlocking knob will cause the first clutch disc to spin freely, preventing it from driving the second clutch disc to rotate, and thus preventing the unlocking action of opening the first locking tongue. Therefore, by setting the first clutch turntable, the second clutch turntable, the first clutch shaft spring, and the first clutch shaft, the disengagement and closure of the first clutch mechanism are made smoother.

[0016] In some embodiments, the first latch box assembly further includes a mechanical lock cylinder and a lock cylinder push rod. The mechanical lock cylinder is installed in the first latch box and is connected to the lock cylinder push rod in a transmission manner. Rotation of the mechanical lock cylinder can drive the lock cylinder push rod to move, and cause the lock cylinder push rod to push the push plate to move.

[0017] In the above technical solution, the user can unlock the mechanical lock cylinder with a key, and the rotation of the mechanical lock cylinder will drive the lock cylinder push rod to move, which in turn will push the push plate to move, thereby mechanically unlocking the first lock tongue box. This design facilitates emergency unlocking.

[0018] In some embodiments, the door lock further includes a second latch box assembly and a second lock hook box assembly. The second latch box assembly includes a second latch box, a second latch, and a second latch drive module. The second latch is disposed within the second latch box, and the second latch drive module is installed in the second latch box. The second lock hook box assembly includes a second lock hook box, a second flexible member, a second slider, a second lock hook, a second spring, and a second lock hook drive module. The second slider is movably disposed within the second lock hook box, and the second lock hook drive module is installed in the second lock hook box. The second lock hook drive module is used to drive the second lock hook to extend out of the second lock hook box to engage with the second latch. The second latch drive module is used to drive the second latch to move so that the second latch is separated from the second lock hook. One end of the second flexible member is connected to the second slider, and the other end is connected to the second lock hook. The second spring is used to drive the second slider to reset. The first latch box assembly is an external latch box assembly, the first lock hook box assembly is an external lock hook box assembly, the second latch box assembly is an internal latch box assembly, and the second lock hook box assembly is an internal lock hook box assembly.

[0019] In the above technical solution, the second lock hook box assembly is identical to the first lock hook box assembly and is arranged mirror-image on the inner and outer sides of the door. The extension and retraction method and transmission principle of the second lock hook are the same as those of the first lock hook: When the second lock hook drive module is activated, it drives the second lock hook to extend out of the second lock hook box and move towards the second latch box, engaging with the second latch. The second lock hook drives the second flexible member and the second slider to move in the same direction, while the second slider and the second lock hook box compress the second spring. When the second latch drive module is activated, it opens the second latch, releasing the second lock hook and the elastic force of the second spring. Under the action of the elastic force of the second spring, the second slider retracts the second flexible member and the second lock hook into the second lock hook box. The second latch box and the first latch box are located on the inner and outer sides of the door, respectively. The difference lies in their unlocking methods: the first latch box's first clutch mechanism requires a push plate to push the first clutch shaft to close, and this pushing can be done mechanically or by motor. The second latch box's clutch mechanism is integrated, with the first and second clutch discs fixedly connected. The second latch box only requires rotating the second unlocking knob to move the second latch up and down, thus unlocking the door from the inside. The locking methods are the same from the inside and outside. When the door is locked from the outside, unlocking can be done via Bluetooth control of the motor or mechanical unlocking with a key. When the door is locked from the inside, simply rotating the second unlocking knob, which then moves the second latch, unlocks the door from the inside. This design is simple in structure, convenient in locking and unlocking, and reduces the risk of unlocking failure due to the inner clutch mechanism not closing.

[0020] In some embodiments, two first latches are provided. The first latch box assembly further includes a first latch turntable, which is rotatably disposed within the first latch box. The first latch turntable connects the two first latches to enable the two first latches to move in tandem. The door lock also includes a latch linkage mechanism that connects the first latches and the second latches to enable the first latches and the second latches to move in tandem; wherein, the second latch drive module can drive the second latch to move so that the second latches separate from the second latch hook.

[0021] In the above technical solution, by setting a first locking tongue turntable, the two locking tongues move synchronously, facilitating the release of the first locking hook. With the door locked from the outside, the user inside rotates the second unlocking knob to activate the second locking tongue. The second locking tongue, through a locking tongue linkage mechanism, moves the first locking tongue, thereby disengaging the first locking hook and unlocking the door. This design ensures the coordinated operation of the first and second locking tongues, achieving the goal of unlocking the door from the inside, while maintaining ease of operation and further enhancing security.

[0022] In some embodiments, the latch linkage mechanism includes a first linkage plate, a second linkage plate, and a third linkage plate. The first latch is provided with a first slot, the second latch is provided with a second slot, and the third linkage plate is provided with a third slot and a fourth slot; one end of the first linkage plate is engaged with the first slot, and the other end is engaged with the third slot; one end of the second linkage plate is engaged with the second slot, and the other end is engaged with the fourth slot.

[0023] In the above technical solution, rotating the unlocking knob inside the door drives the second latch to move up and down via a transmission mechanism. The second slot on the second latch drives the second linkage plate to move upward, which in turn drives the third linkage plate to move upward. The third linkage plate then drives the first linkage plate to move upward, which in turn drives the first latch to move upward. The first and second latches are linked and controlled by the latch turntable, which controls the double latches in the same latch box. This linkage design is simple in structure and allows for simultaneous unlocking from both inside and outside the door via the second unlocking knob, combining operational efficiency with emergency escape requirements.

[0045] In the description of the embodiments of this application, it should be noted that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use, or the orientation or positional relationship commonly understood by those skilled in the art, and is only for the convenience of describing this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. In addition, the terms "first," "second," "third," etc. are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0046] Please refer to Figure 1 , Figure 2 . Figure 1 This is a cross-sectional view of the first latch box and the first lock hook box. Figure 2 This is a front view of the first latch box and the first hook box. Figure 1 and Figure 2The first latch box assembly 1 mainly includes a first latch box 11, a first latch 12, and a first latch drive module 13. The first latch 12 is disposed within the first latch box 11, and the first latch drive module 13 is installed in the first latch box 11. The first hook box assembly 2 includes a first hook box 21, a first flexible member 22, a first slider 23, a first hook 24, a first spring 25, and a first hook drive module 26. The first slider 23 is movably disposed within the first hook box 21, and the first hook drive module 26 is installed in the first hook box 21. The first hook drive module 26 is used to drive the first hook 24 to extend out of the first hook box 21 to engage with the first latch 12; the first latch drive module 13 is used to drive the first latch 12 to move so that the first latch 12 separates from the first hook 24. One end of the first flexible member 22 is connected to the first slider 23, and the other end is connected to the first hook 24. The first spring 25 is used to drive the first slider 23 to reset.

[0047] When the first locking hook drive module 26 drives the first locking hook 24 to extend out of the first locking hook box 2 and engage with the first locking tongue 12, the first spring 25 stores force under the combined compression of the first slider 23 and the first locking hook box 21.

[0048] When the first latch drive module 13 drives the first latch 12 to move, causing the first latch 12 to separate from the first lock hook 24, the compressed elastic force of the first spring 25 is released and drives the first slider 23 to move. The first slider 23 simultaneously pulls the first flexible member 22 to move, causing the first flexible member 22 to pull the first lock hook 24 back into the first lock hook box 21.

[0049] It should be noted that when the first hook drive module 26 drives the first hook 24 to extend from the first hook box 2 and engage with the first latch 12, it means that the first hook drive module 26 can control the first hook 24 to move toward the first latch 12. The function of the first latch 12 is to prevent the first hook 24 from moving relative to the first hook box 21. When the first latch drive module 13 drives the first latch 12 to move, causing the first latch 12 to separate from the first hook 24, it means that the first latch drive module 13 controls the first latch 12 to open. The first latch 12 has no restrictive effect on the first hook 24, and the first hook 24 can move relative to the first hook box 21.

[0050] The first latch box 11 has a rectangular shell structure and is fixed to one edge of the glass door frame by adhesive on the back plate, serving to accommodate and cooperate with other components. The first latch 12 is vertically movable within the first latch box 11 and is controlled by the first latch drive module 13. The first latch 12 engages with the first lock hook 24. The first latch drive module 13 is located within the first latch box 11 and controls the extension and retraction of the first latch 12. This design is simple in construction, the force transmission relationship is safe and reliable, and it can effectively reduce the failure rate.

[0051] The design of the first lock hook drive module 13 allows the flexible first lock hook 24 to smoothly engage with the first lock tongue 12. Furthermore, the design of the first slider 23 and the first spring 25 allows the first lock hook 24 to smoothly retract into the first lock hook box 21. Through the above scheme, the first lock tongue 12 and the first lock hook 24 engage and disengage relatively smoothly and stably. The first flexible member 22, after locking, can be bent, preventing impact damage caused by door misalignment due to door installation errors or external forces.

[0052] Among them, the first flexible component 22 is a chain, such as Figure 5 and Figure 6 As shown.

[0053] Figure 5 This is a structural diagram of the first flexible component 22 used in this embodiment. The first flexible component 22 uses a stainless steel chain, which is formed by hinged multi-section chain plates 222 through flat round-headed mating rivets 221. This ensures that the chain can move flexibly in the horizontal direction while restricting displacement in the vertical direction. The assembly method of the chain allows it to extend and retract only in the direction of door lock opening and closing (horizontal direction), avoiding lateral pulling or twisting caused by door misalignment. When the door is slightly misaligned due to installation errors or external forces, the horizontal movement characteristics of the chain can absorb the displacement deviation, preventing hard collisions between the lock and the door frame, thereby protecting the door structure from damage. This specially designed chain works in conjunction with the first spring 25 to adaptively adjust its position when the door misaligns, avoiding rigid impacts or damage to the door structure. Figure 6 A magnified view of the lock body in the locked state shows that the chain is designed to be flexible and extendable when locked, which can effectively adapt to door misalignment. The chain adaptively adjusts the connection angle and tension through the flexible rotation of rivet 221 and the elastic contraction of the first spring 25, avoiding the problem of traditional solid connectors easily jamming when the door is misaligned.

[0054] In an alternative solution, the first flexible component 22 can also be made of steel cable or ordinary iron chain, but the first flexible component 22 in the alternative solution will move in the vertical direction, causing the first flexible component 22 to sag. This alternative solution may cause the locking hook to jam.

[0055] like Figure 1 and Figure 8 As shown, Figure 8 This is a structural diagram of the first storage tube. The first locking hook drive module 26 includes a first storage tube 261, a first ejection tube 262, and a first locking knob 263. The first storage tube 261 is fixed inside the first locking hook box 21, and the first slider 23 is movably disposed inside the first storage tube 261. The two ends of the first spring 25 abut against the first storage tube 261 and the first slider 23, respectively. Figure 7As shown, the first ejector tube 262 is provided with a first end wall 2621 and a first peripheral wall 2622. The first end wall is provided with a first through hole 26211. The bottom of the first ejector tube 262 has a protrusion 2623, and the protrusion 2623 is provided with a second through hole 26231. Figure 7 This is a schematic diagram of the first ejector tube. The first receiving tube 261 has a second end wall 2611, and a third through hole 26111 is provided on the second end wall. An ejector tube slot 26221 is provided on the first peripheral wall 2622. (The last sentence appears to be incomplete and possibly refers to a different diagram.) Figure 9 This is a structural diagram of the first launch turntable 2631.

[0056] The first receiving tube 261, the first pushing tube 262 and the first locking knob 263 work together to make the first locking hook 24 smoothly engage with the first locking tongue 12, making the engagement between the first locking tongue 12 and the first locking hook 24 smoother and more reliable.

[0057] like Figure 3 , Figure 12 , Figure 3 This is a cross-sectional view of the first locking hook box 2. The first locking hook box assembly 2 also includes a first push-out spring 27 and a push-out spring guide shaft 28. The first push-out spring 27 is disposed inside the first locking hook box 21. One end of the push-out spring guide shaft 28 is connected to the first locking hook box 21, and the other end can freely pass through the second through hole 26231. The two ends of the first push-out spring 27 abut against the first locking hook box 21 and the first push-out tube 262, respectively, and are sleeved on the push-out spring guide shaft 28. The first push-out spring 27 is used to drive the first push-out tube 262 and the first locking knob 263 to reset.

[0058] The first push tube 262 is movably sleeved outside the first receiving tube 261. The first through hole 26211 of the first push tube 262 has the same inner diameter as and contacts the third through hole 26111 of the first receiving tube 261. The first locking hook 24 is locked outside the first through hole 26211. The first flexible member 22 passes through the first through hole 26211 and the third through hole 26111, and its two ends are respectively connected to the first locking hook 24 and the first slider 23. The two ends of the first spring 25 abut against the third through hole 26111 and the first slider 23 respectively. The push tube slot 26221 is connected to the first locking knob 263.

[0059] When the first locking hook drive module 26 is activated to move the first locking hook 24, the first locking knob 263 is rotated to drive the ejection turntable 2631 to rotate. The ejection turntable 2631 drives the ejection tube slot 26221 on the first ejection tube 262 through the ejection turntable protrusion (not marked in the figure), so that the rotational motion of the first locking knob 263 is converted into the axial movement of the first ejection tube 262 along the first receiving tube 261. The first through hole 26211 on the first ejection tube 262 pushes the first locking hook 24 to move, so that the third through hole 26111 and the first slider 23 compress the first spring 25 to store force.

[0060] After the first latch 12 and the first hook 24 are fully engaged, the user releases the first locking knob 263, causing the elasticity of the first push-out spring 27 to be released. The first push-out tube 262 is then retracted into the first hook box 21, and the first push-out tube 262 drives the first locking knob to reset via the push-out turntable 2631. When the first latch drive module 13 is activated, it moves the first latch 12 to finally fully release the first hook 24. The release of the elasticity of the first spring 25 pushes the first slider 23 to reset. The first slider 23, along with the first flexible member 22 and the first hook 24, retracts into the first hook box 21.

[0061] In the alternative scheme where the first locking tongue drive module 13 drives the first ejector tube 262 to move, the drive can be achieved not only by the ejector turntable 2631, but also by chain drive or gear drive.

[0062] In this embodiment, there are two of each of the first ejection spring 27, the spring guide shaft 28, and the second through hole 26231, respectively designed on the upper and lower sides of the first ejection tube 262. This design allows the first ejection tube 262 to be subjected to more even force, improving the working stability of the lock body. This reset method is smooth and reliable, thereby improving the synchronization of the reset of each component, reducing the risk of impact noise during mechanism reset, and improving the smoothness of knob operation.

[0063] like Figure 1 and Figure 2As shown, the first latch drive module 13 includes a first unlocking knob 131, a motor module 132, and a first clutch mechanism 133. The first unlocking knob 131 is rotatably mounted in the first latch box 11. The motor module 132 and the first clutch mechanism 133 are both located inside the first latch box 11. The first unlocking knob 131 and the first latch 12 are connected via the first clutch mechanism 133. The first clutch mechanism 133 has a disengaged state and an engaged state. The motor module 132 drives the first clutch mechanism 133 to switch from the disengaged state to the engaged state. When the motor module 132 drives the first clutch mechanism 133 to the engaged state, rotating the first unlocking knob 131 drives the first clutch mechanism 133 to open the first latch 12 and release the first locking hook 24, thus unlocking. When the first clutch mechanism 133 is in the disengaged state, rotating the first unlocking knob 131 cannot drive the first clutch mechanism 133 to the first latch 12, and therefore unlocking cannot be achieved.

[0064] The first clutch mechanism 133 connects the first unlocking knob 131 and the motor module 132, which can effectively enhance the reliability and security of the unlocking operation.

[0065] In this embodiment, as Figure 1 , Figure 10 and Figure 13 As shown, the first clutch mechanism 133 includes a first clutch turntable 1331, a second clutch turntable 1332, a first torsion spring 1335, a second torsion spring 1336, a first clutch shaft spring 1333, a first clutch shaft 1334, a first magnetic component 16, and a first detection component 17.

[0066] The first clutch disc 1331 is connected to the first unlocking knob 131, the second clutch disc 1332 is connected to the first locking tongue 12, the first clutch shaft 1334 is installed on the first clutch disc 1331, the first clutch shaft spring 1333 is sleeved on the first clutch shaft 1334, the two ends of the first clutch shaft spring 1333 abut against the first clutch shaft 1334 and the first clutch disc 1331 respectively, the two ends of the first torsion spring 1335 are connected to the first clutch disc 1331 and the first locking tongue box 11 respectively, the two ends of the second torsion spring 1336 are connected to the second clutch disc 1332 and the first locking tongue box 11 respectively, the first magnetic element 16 is disposed on the first clutch shaft 1334, and the first detection element 17 is disposed inside the first locking tongue box 11.

[0067] like Figure 1 , Figure 11As shown, the first latch box assembly 1 also includes a latch lever 124, which is rotatably mounted in the first latch box 11. The latch lever 124 has a protrusion 126 at its fixed end and another protrusion 125 at its movable end, with the protrusion 125 abutting against the first latch 12. The second clutch turntable 1332 has a slot 13321 corresponding to the first clutch shaft 1334, and also has a strip-shaped protrusion 13322 that abuts against the protrusion 126 of the latch lever 124.

[0068] In this embodiment, as Figure 1 , Figure 2 As shown, the motor module 132 includes a motor 1321 and a push plate 1322. The motor 1321 drives the push plate 1322 to move, and the push plate 1322 pushes the first clutch shaft 1334 to move, so that the first clutch shaft 1334 connects the first clutch turntable 1331 and the second clutch turntable 1332. When the first unlocking knob 131 is turned, causing the first clutch shaft 1334 on the first clutch turntable 1331 to move, the first magnetic element 16 on the first clutch shaft 1334 will vibrate, which will be detected by the first detection element 17, waking up the motor module 132 and flashing the indicator light 1323. The user can control the awakened motor module 132 through a mobile app. After receiving the corresponding command, the motor module 132 will extend the push plate 1322. This design can wake up the motor module 132 when unlocking and put the motor module 132 into a dormant state when locking. By setting the first magnetic element 16 and the first detection element 17, the motor module 132 does not need to be constantly powered, which can effectively save energy for the motor module 132. For the sake of sensing effect, the first detection element 17 uses a reed switch, and the first magnetic element 16 uses a magnet. Figure 10 As shown.

[0069] When the motor module 132 is started, the push plate 1322 pushes the first clutch shaft 1334 into the slot 13321 of the second clutch turntable 1332, realizing the engagement of the first clutch turntable 1331 and the second clutch turntable 1332. At the same time, the first clutch shaft spring 1333 is compressed to store force, and the first clutch mechanism 133 is closed. 30 seconds after the motor module 132 is turned on, the push plate 1322 is retracted. Under the elastic release of the first clutch shaft spring 1333, the first clutch shaft 1334 is pushed out of the second clutch turntable 1332, the first clutch turntable 1331 and the second clutch turntable 1332 are separated, and the first clutch mechanism 133 is disengaged.

[0070] When the first clutch mechanism is engaged, the user rotates the first unlocking knob 131, compressing the first torsion spring 1335, which in turn causes the first clutch disc 1331, the first clutch shaft 1334, and the second clutch disc 1332 to rotate simultaneously. The second clutch disc 1332 compresses the second torsion spring 1336, as shown below. Figure 13This is a schematic diagram of the structure of the first torsion spring 1335 and the second torsion spring 1336. When the first clutch shaft 1334 drives the second clutch turntable 1332, the push plate 1322 will not abut against the first clutch shaft 1334, causing the first clutch shaft 1334 to disengage from the second clutch turntable 1332. However, the rebound force generated by the compression of the first torsion spring 1335 and the second torsion spring 1336 will cause the side wall of the first clutch shaft 1334 to press against the side wall of the second clutch turntable 1332, generating friction. The friction is greater than the elastic force of the first clutch shaft spring 1333. The resulting friction allows the first clutch shaft 1334 to stably close the first clutch mechanism 1331 when rotating. Furthermore, the rotation of the second clutch dial 1332 causes the strip-shaped protrusion 13322 to push the protrusion 126 at the rotating end of the latch lever 124, causing the latch lever 124 to rotate around its axis. The protrusion 125 at the movable end of the latch lever 124 pushes the first latch 12 to move, thereby opening the first latch 12 and releasing the first lock hook 24 to achieve unlocking. After unlocking, when the user releases the first unlocking knob 131, the elasticity of the first torsion spring 1335 and the second torsion spring 1336 will be released. The elasticity of the first torsion spring 1335 will cause the first unlocking knob 131 to reset, and the elasticity of the second torsion spring 1336 will cause the second clutch dial 1332 to reset.

[0071] When the first clutch mechanism 133 is disengaged, the first clutch shaft on the first clutch turntable is not inserted into the second clutch turntable slot 13321. When the user rotates the first unlocking knob 131, the first clutch turntable 1331 will rotate freely, and unlocking cannot be achieved in this state.

[0072] By setting the first torsion spring 1335 and the second torsion spring 1336, not only can the first unlocking knob 131 and the second clutch disc 1332 be easily reset, but the risk of the first clutch shaft 1334 disengaging from the second clutch disc 1332 during operation can also be reduced. By setting the first magnetic component 16 and the first detection component 17, the motor module 132 does not need to be in a constantly powered state, thereby achieving energy saving and increasing the service life of the lock.

[0073] Furthermore, the push plate 1322 of the motor module 132 can also be driven mechanically. For example... Figure 1 , Figure 2 , Figure 12 As shown, the first lock tongue box assembly 1 also includes a mechanical lock cylinder 14, a lock cylinder turntable 141, and a lock cylinder push rod 15. The lock cylinder turntable 141 has protrusions 1411, and the lock cylinder push rod 15 has corresponding slots 151, with the protrusions 141 and slots 151 abutting against each other. The protrusions 141 and slots 151 are used to convert the rotational motion of the lock cylinder turntable 141 into the linear motion of the lock cylinder push rod 15. The mechanical lock cylinder 14 is mounted on the first lock tongue box 11, and the mechanical lock cylinder 14 and the lock cylinder push rod 15 are connected via the lock cylinder turntable 141.

[0074] In some cases, users may not be able to unlock using the app. For example... Figure 12 The diagram shown is an exploded view of the mechanical unlocking mechanism. The user can turn the mechanical lock cylinder 14 with a key. The mechanical lock cylinder 14 drives the lock cylinder disc 141 to rotate, which in turn moves the lock cylinder push rod 15 horizontally. The push rod 15 then pushes the push plate 1322, which in turn pushes the first clutch shaft 1334, engaging the first clutch mechanism 133. Turning the first unlocking knob 131 will activate the first clutch mechanism 133, which in turn moves the first lock tongue 12 via the lock tongue lever 124, releasing the first lock hook 24 and completing the unlocking process. This design allows for emergency unlocking, improving security.

[0075] like Figure 1 As shown, the first latch box assembly 1 also includes a first latch spring 18, which is disposed inside the first latch box 1. The two ends of the first latch spring 18 abut against the first latch box 1 and the first latch 12, respectively. The first latch box 11 is fixed, while the first latch 12 is movable. The function of the first latch spring 18 is to reset the first latch 12 after it has been moved.

[0076] When the first hook 24 is inserted into the first latch 12, the first latch spring 18 is compressed and stores force under the pressure of the first latch 12 and the first latch box 11. When the first hook 24 is fully inserted into the first latch 12, the elastic force of the first latch spring 18 is released, causing the first latch 12 to engage the first hook 24. When the first latch 12 is opened by the first latch drive module 13, the movement of the first latch 12 compresses and stores force in the first latch spring 18. When the first latch 12 is opened by the first latch drive module 13 and the first hook 24 is released, the elastic force of the first latch spring 18 is released, causing the first latch 12 to return to its original position. By setting the first latch spring 18, the first latch 12 can smoothly release or engage the first hook 24.

[0077] It should be noted that "the first hook 24 is submerged in the first latch 12" means that the inclined guide surface at the end of the first hook 24 is pressed against the first latch 12 by the first latch drive module 13 and gradually enters the first latch 12. During this process, the first hook 24 moves relative to the first latch 12. "The first hook 24 is completely submerged in the first latch 12" means that the first hook 24 is completely entered into the first latch 12 under the action of the first hook drive module 13, and the first hook 24 can no longer move relative to the first latch 12.

[0078] The opening of the first latch 12 by the first latch driving module 13 refers to the process by which the first latch driving module 13 opens the first latch 12. The opening of the first latch 12 by the first latch driving module 13 and the release of the first locking hook 24 means that the first latch 12 is fully opened under the action of the first latch driving module 13 until it no longer restricts the first locking hook 24.

[0079] In this embodiment, the first locking tongue spring 18 is located between the first locking tongue box 1 and the first locking tongue 12. The first locking tongue spring 18 can be elastic rubber, rubber band, etc.

[0080] Furthermore, such as Figure 1 and Figure 15 As shown, Figure 15 This is an exploded view of the latch linkage mechanism 5. The first latch 12 has two parts, upper and lower, and a first latch turntable 19 is engaged in the middle of the first latch 12. The first latch box assembly 1 also includes the first latch turntable 19, which is rotatably disposed within the first latch box 11. The first latch turntable 19 connects the two first latches 12, enabling them to move in unison. Each of the two first latches 12 has a groove; the upper first latch 12 has an upper groove 121, and the lower first latch 12 has a lower groove 122. The first latch turntable 19 has two opposing protrusions, including an upper protrusion 191 and a lower protrusion 192. The upper groove 121 and lower groove 122 of the first latch are used to abut against the upper protrusion 191 and lower protrusion 192 of the first latch turntable, facilitating the transmission and reception of forces related to the first latch 12 by the first latch turntable 19. The upper protrusion 191 of the first latch turntable abuts against the edge of the upper groove 121, and the lower protrusion 192 of the first latch turntable abuts against the edge of the lower groove 122.

[0081] When the user rotates the first unlocking knob 131, which drives the first clutch mechanism 33, if the upper first latch 12 moves upward, the groove 121 on the first latch drives the protrusion 191 on the first latch turntable to rotate. This rotation, in turn, drives the lower protrusion 192 of the first latch turntable to rotate. The rotation of the lower protrusion 192 abuts against the lower groove 122 of the first latch, causing it to move downward. Consequently, the lower first latch 12 moves downward, achieving linkage between the two latches via the first latch turntable 19. Similarly, if the lower first latch 12 moves, the upper first latch 12 will move in the same manner.

[0082] Without the first latch turntable 19, the first latch 12 can only open one latch under the first latch drive 13, and cannot fully open the first latch 12. This can easily cause the first hook 24 to get stuck because the first latch 12 is not fully open. The two latches of the first latch 12 move synchronously through the first latch turntable 19, so that the first hook 24 can be released smoothly.

[0083] Furthermore, the sectional view and external schematic diagram of the second locking tongue box 31 and the second locking hook box 41 can be found in the following figures. Figure 3 and Figure 4 The door lock structure also includes a second latch box assembly 3 and a second latch hook box assembly 4. The second latch box assembly 3 includes a second latch box 31, a second latch 32, a second latch spring 35, and a second latch drive module 33. The second latch 32 is disposed within the second latch box 31, and the second latch drive module 33 is mounted on the second latch box 31. The second latch drive module 33 includes a second unlocking knob 331 and a second clutch mechanism 332. The second clutch mechanism 332 includes a third clutch dial 3321, a fourth clutch dial 3322, a third torsion spring 3323, and a fourth torsion spring 3324. The second latch spring 35 is disposed within the second latch box 31, with its two ends abutting against the second latch box 31 and the second latch 32, respectively. The fourth clutch dial 3322 has a strip-shaped protrusion 33221. The second latch box assembly 3 also includes a latch lever 34, which is rotatably mounted within the first latch box 11. The latch lever 34 has a fixed end with a protrusion 341 and a movable end with another protrusion 342. The fixed end protrusion 341 abuts against the strip-shaped protrusion 33221 on the fourth clutch dial 3322, and the movable end protrusion 342 abuts against the second latch 32. Figure 3 The second hook box assembly 4 includes a second hook box 41, a second flexible member 42, a second slider 43, a second hook 44, a second spring 45, and a second hook drive module 46. The second slider 43 is movably disposed within the second hook box 41, and the second hook drive module 46 is installed within the second hook box 41. The second hook drive module 46 includes a second receiving tube 461, a second pushing tube 462, and a second locking knob 463, operating on the same principle as the first hook drive module 26.

[0084] The second lock hook drive module 46 drives the second lock hook 44 to extend out of the second lock hook box 41 to engage with the second lock tongue 32; the second lock tongue drive module 33 drives the second lock tongue 32 to move, so that the second lock tongue 32 separates from the second lock hook 44. The second clutch mechanism 332 drives the movement of the second lock tongue 32, the third torsion spring 3323 resets the second unlocking knob 331, and the fourth torsion spring 3324 resets the second clutch mechanism 332 as a whole. The second lock tongue spring 35 resets the second lock tongue 32.

[0085] One end of the second flexible member 42 is connected to the second slider 43, and the other end is connected to the second locking hook 44. The second spring 45 is used to drive the second slider 43 to reset. The second flexible member 42 is a chain with the same material and structure as the first flexible member 22.

[0086] Among them, the first latch box assembly 1 is the door external latch box assembly, the first lock hook box assembly 2 is the door external lock hook box assembly, the second latch box assembly 3 is the door internal latch box assembly, and the second lock hook box assembly 4 is the door internal lock hook box assembly.

[0087] The second lock hook box assembly 3 and the first lock hook box assembly 2 are located on the inner and outer sides of the door, respectively. The internal components and lock hook drive principle are the same. The second lock tongue box 31 and the first lock tongue box 11 are located on the inner and outer sides of the door, respectively. The difference between the two lies in the unlocking method: the first clutch mechanism 133 of the first lock tongue box 11 needs to be pushed by the push plate 1322 to close the first clutch shaft 1334. The pushing method of the push plate 1322 includes both mechanical and motor types. The second clutch mechanism 332 of the second lock tongue box 31 is itself integrated, that is, the third clutch turntable 3321 and the fourth clutch turntable 3322 are fixedly connected. The second lock tongue box 31 only needs to rotate the second unlocking knob 331 to drive the second lock tongue 32 to move up and down, thereby realizing the unlocking of the door from the inside.

[0088] Specifically, the user rotates the second unlocking knob 331 to compress the third torsion spring 3323, which in turn causes the third clutch disc 3321 and the fourth clutch disc 3322 to rotate simultaneously. The third clutch disc 3321 compresses the fourth torsion spring 3324. The rotation of the fourth clutch disc 3322 causes the strip-shaped protrusion 33221 to push the protrusion 341 at the fixed end of the latch lever 34, causing the latch lever 34 to rotate around its axis. The protrusion 342 at the movable end of the latch lever 34 pushes the second latch 32 to move, while simultaneously compressing the second latch spring 35. This opens the second latch 32, releasing the second locking hook 44 to unlock. After the second locking hook 44 is released, the elastic force of the second latch spring 35 is released, causing the second latch 32 to return to its original position.

[0089] The locking methods are the same both inside and outside the door. When the door is locked from the outside, it can be unlocked via Bluetooth control of the motor module 132 or mechanical unlocking; when the door is locked from the inside, simply turning the second unlocking knob 331 and transmitting it to the second latch 32 will unlock the door from the inside. The clutch device inside the door always remains closed, which can reduce the risk of unlocking failure caused by the clutch mechanism not being closed.

[0090] Furthermore, such as Figure 1 , Figure 3 , Figure 14 and Figure 15 , Figure 14This is an assembly drawing of the latch linkage mechanism 5. The second latch box assembly 3 also includes the latch linkage mechanism 5 and the second latch turntable 39. Figure 15 This is an exploded view of the latch linkage mechanism 5. The latch linkage mechanism 5 connects the first latch 12 and the second latch 32, enabling them to move in tandem. Specifically, the second latch drive module 33 can move the second latch 32, causing it to separate from the second lock hook 44. The second latch 32 also comprises upper and lower parts. The second latch turntable 39 drives the movement of these two parts; after the upper part of the second latch 32 moves, the turntable 39 drives the lower part to move as well. This design allows the latch to be fully opened, improving the security and reliability of the door lock and preventing the risk of people inside being locked out by the outer door.

[0091] Among them, reference Figure 14 , Figure 15 The latch linkage mechanism 5 includes a first linkage plate 51, a second linkage plate 52, and a third linkage plate 53. The first latch 12 has a first slot 123, the second latch 32 has a second slot 323, and the third linkage plate 53 has a third slot 531 and a fourth slot 532. A latch cover plate 6 with a sliding groove is also fixedly installed on the first latch box 11 and the second latch box 31. The first linkage plate 51 is slidably disposed within the sliding groove of the latch cover plate 6 of the first latch box 11, with one end engaged in the first slot 123 and the other end engaged in the third slot 531. The second linkage plate 52 is slidably disposed within the sliding groove of the latch cover plate 6 of the second latch box 31, with one end engaged in the second slot 323 and the other end engaged in the fourth slot 532. The design of the three linkage plates being engaged with slots helps to limit the first latch 12 and the second latch 32 to only vertical movement, preventing lateral offset.

[0092] When the user activates the second latch drive module 33 to move the second latch 32 upward, the second slot 323 of the second latch 32 pushes the second linkage plate 52 upward. One end of the second linkage plate 52, abutting against the fourth slot 532 of the third linkage plate 53, pushes the third linkage plate 53 upward. The third slot 531 of the third linkage plate 53, abutting against the first linkage plate 51, pushes the first linkage plate 51 upward. The first linkage plate 51, abutting against the first slot 123 of the first latch 12, pushes the first latch 12 upward. The linkage principle of the upper and lower latches of the second latch 32 is the same as that of the first latch 12: inside the second latch box 31, when the upper latch portion of the second latch 32 moves upward, it drives the second latch turntable 39 to rotate. The rotation of the second latch turntable 39 then drives the lower latch portion of the second latch 32 downward, ultimately achieving full opening of the second latch. The first latch 12 also links the upper and lower latch portions of the first latch 12 via the first latch turntable 19, pushing the lower portion of the first latch 12 downward to fully open the first latch. As described above, by driving the upper latch portion of the second latch 32, both the first latch 12 and the second latch 32 can be fully opened simultaneously.

[0093] When the user activates the second latch drive module 33, causing the second latch 32 to move downwards, the lower part of the first latch 12 is opened via the aforementioned transmission principle. The upper parts of the first latch 12 and the second latch 32 are also opened by the transmission of the first latch turntable 19 and the second latch turntable 39, respectively. This situation also allows the latch to be fully opened, thus achieving unlocking.

[0094] The user activates the second latch drive module 33 to move the second latch 32 up or down. This means that: rotating the second unlock knob 331 clockwise will cause the lower part of the second latch 32 to move down; rotating the second unlock knob 331 counterclockwise will cause the upper part of the second latch 32 to move up.

[0095] Furthermore, the first linkage plate 51, the second linkage plate 52, and the third linkage plate 53 can not only be used to link the inner and outer locking tongues, but also to adapt to different door thicknesses. For example... Figure 14 As shown, the manufacturer can customize the horizontal width of the third linkage plate 53 or the groove depth of the third slot 531 and the fourth slot 532 according to the user's door thickness. During installation, the user can also adjust the positions of the ends of the first linkage plate 51 and the second linkage plate 52 in the third slot 531 and the fourth slot 532 according to the actual door thickness. Through the design of the latch linkage mechanism 5, not only can people inside the door unlock the door from the outside, improving security, but the lock body can also be adapted to doors of different thicknesses, reducing the manufacturer's production costs.

[0096] The above embodiments are merely preferred embodiments of the present invention. Any modifications or equivalent substitutions made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
