Description

Technical Field

[0001] This application relates to the field of smart lock structure technology, specifically to a mechanical structure of a smart lock. Background Technology

[0002] Since their introduction, smart lock products have undergone decades of continuous innovation and development, yet the fundamental problem of seamless installation—including the ability to monitor lock status electronically regardless of whether the lock opens from the left or right, inside or outside—remains unresolved. The vast majority of products on the market still rely on on-site installation by technicians. Even some improved products suffer from limitations in technology, complex structures, and low reliability, failing to address the existing issues. To date, no product can simultaneously monitor the lock's status via detection devices in emergency situations, whether using a handle-type mechanical key or a key on the lock body or panel. Summary of the Invention

[0003] This application aims to address the problem that existing technologies cannot monitor the door lock status in case of emergency using either the handle-type mechanical key or the key on the lock body panel. It provides a mechanical structure for a smart lock that allows monitoring of the door lock status using the same electronic component regardless of whether the door lock is on the left or right side, or whether an emergency is initiated via the mechanical key on the handle or the mechanical key on the lock body.

[0004] A smart lock's mechanical structure includes a housing with a cavity, a movable latch mechanism with one end located inside the cavity and the other end extending through the front exterior of the housing, and a movable lock head mechanism extending through the front exterior of the housing, an inner handle and an outer handle respectively located on the left and right sides of the housing, and the housing also includes a handle-type unlocking device and a panel lock-type unlocking device. The handle-type unlocking device and the panel lock-type unlocking device respectively abut against a micro switch component. When unlocking, the handle-type unlocking device or the panel lock-type unlocking device contacts and energizes the micro switch component, forming an unlocking signal and transmitting it to an electronic system for monitoring.

[0005] The handle-type unlocking device includes: a clutch mechanism located inside the housing cavity, one end of which is used to drive the locking tongue mechanism to translate for unlocking;

[0006] A normally open shaft is provided on the side of the inner handle near the clutch mechanism for rotating and driving the clutch mechanism, so that the locking tongue mechanism moves with the clutch mechanism. The normally open shaft is inserted into the clutch mechanism and is connected to the clutch mechanism.

[0007] An idle shaft is provided on the side of the outer handle near the clutch mechanism and can be connected to the clutch mechanism. The front end of the idle shaft that is connected to the clutch mechanism is provided with a square shaft. An idle cylinder with the same diameter as the clutch mechanism is provided between the idle shaft and the square shaft. The rear end of the idle cylinder is located on the idle shaft and is provided with an elastic retaining spring for abutting the square shaft.

[0008] A first locking slot is provided on the outside of the outer handle for unlocking the locking tongue mechanism;

[0009] The panel lock type unlocking device includes: a swing arm; a fixed shaft located in the middle of the swing arm and fixed in the housing; and a second lock for unlocking the swing arm. When unlocking, the lower end of the swing arm rotates around the fixed shaft and contacts the micro switch component to be energized, forming an unlocking signal and transmitting it to the electronic system for monitoring.

[0010] As described above, the mechanical structure of the smart lock includes a clutch mechanism comprising a clutch sleeve that abuts against one end of the latch mechanism for driving the latch mechanism to translate, a reverse lifting rotating plate disposed on the clutch sleeve and cooperating therewith, and a free-rotating sleeve fixed inside the reverse lifting rotating plate. The end of the normally open shaft away from the handle sleeve is connected to the reverse lifting rotating plate, and the square shaft is connected to the free-rotating sleeve. The clutch sleeve is provided with a clutch pin that can be inserted into the periphery of the free-rotating sleeve. When the clutch pin is away from the free-rotating sleeve, the square shaft and the free-rotating sleeve can rotate freely relative to the clutch sleeve. When the clutch pin is inserted into the free-rotating sleeve, the clutch sleeve and the free-rotating sleeve are connected. The free-rotating shaft can drive the free-rotating sleeve to drive the clutch sleeve to unlock the latch mechanism. The lower side of the free-rotating sleeve abuts against the micro switch component.

[0011] When the unlocking component is inserted into the first lock and rotated, the empty rotating sleeve contacts the micro switch component and is energized, forming an unlocking signal and transmitting it to the electronic system for monitoring.

[0012] As described above, the mechanical structure of the smart lock includes a toothed plate inserted inside the idler sleeve for emergency unlocking. A guide groove corresponding to the toothed plate is provided inside the idler sleeve for its reciprocating motion. A limit groove is formed on the lower side of the clutch sleeve corresponding to the guide groove. During unlocking, the toothed plate moves downwards and abuts against the limit groove. The idler shaft is integrated with the idler sleeve and the clutch sleeve. The toothed plate inside the idler sleeve drives the clutch sleeve to unlock the latch mechanism. The toothed plate moves downwards and contacts the microswitch component, energizing it and generating an unlocking signal, which is transmitted to the electronic system for monitoring.

[0013] As described above, in the mechanical structure of the smart lock, an elastic element for resetting the clutch pin is provided between the clutch pin and the clutch sleeve, and a transmission component for pushing the clutch pin into the empty sleeve is provided at the end of the clutch pin away from the empty sleeve.

[0014] As described above, in the mechanical structure of the smart lock, the transmission assembly includes a push plate for pushing the clutch pin and a drive member for driving the push plate to move, wherein the push plate and the drive member are connected in a transmission manner.

[0015] As described above, the mechanical structure of the smart lock includes a mechanical key inside the idle shaft that can drive the toothed plate to reciprocate by rotation. One end of the mechanical key is inserted into the toothed plate, and the other end passes through the idle shaft and is connected to the first lock opening.

[0016] As described above, the mechanical structure of the smart lock includes an insertion port on the toothed plate for inserting the mechanical key, and a positioning guide groove located below the insertion port for the toothed plate to slide up and down. The hollow sleeve has a limiting shaft passing through the positioning guide groove for connecting the toothed plate and the hollow sleeve.

[0017] As described above, in the mechanical structure of the smart lock, the swing arm can rotate around the fixed axis to drive the transmission assembly to move, the lower end of the swing arm abuts against the micro switch component, and the upper end of the swing arm is located on one side of the second lock opening;

[0018] The second lock is provided with a paddle for pushing the swing arm to rotate around the fixed axis, and the pushing end of the swing arm pushes the transmission assembly to insert the clutch pin into the empty rotating sleeve.

[0019] As described above, in the mechanical structure of the smart lock, a latch limiting piece is detachably provided on the other side of the contact point between the clutch housing and the latch mechanism for limiting the clutch housing. The latch limiting piece is fixed to the side of the clutch housing away from the contact point by fasteners.

[0020] As described above, the mechanical structure of the smart lock includes a lock head mechanism that can freely extend and retract inside and outside the housing, a square shaft rocker arm for driving the lock head to reciprocate, and a transmission plate with one end connected to the square shaft rocker arm and the other end abutting against the clutch sleeve. When the square shaft rocker arm rotates, it drives the lock head to move outward from the housing, and the transmission plate translates in the direction of rotation of the square shaft rocker arm and abuts against the clutch sleeve.

[0021] Compared with the prior art, the beneficial effects of this application are as follows:

[0022] This application provides a mechanical structure for a smart lock. By incorporating a handle-type unlocking device and a panel-type unlocking device, both of which abut against a micro-switch component, when unlocking is required, the handle-type or panel-type unlocking device contacts and energizes the micro-switch component, generating an unlocking signal that is transmitted to the electronic system for monitoring. This enables the system to record and control functions, allowing the electronic system to monitor the lock's status via detection devices regardless of whether an emergency key is used on the handle, lock body, or panel. This solves the problems of left / right locks, convenient bolt reversal, and lock reliability. Furthermore, it addresses the challenge of using the same electronic component to monitor the lock's status during emergency situations, whether using a mechanical key on the handle or lock body.

[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] like Figure 1-7 As shown, the mechanical structure of a smart lock includes a housing 1, a bolt mechanism 2, a lock head mechanism 3, an inner handle 4, an outer handle 5, a clutch mechanism 6, a micro switch component 7, a transmission assembly 8, and a bolt limiting plate 9.

[0033] A smart lock's mechanical structure includes a housing 1 with a accommodating cavity, a movable bolt mechanism 2 with one end located inside the accommodating cavity and the other end extending through the front exterior of the housing 1, and a movable lock head mechanism 3 extending through the front exterior of the housing 1. An inner handle 4 and an outer handle 5 are respectively located on the left and right sides of the housing 1. The housing 1 also includes a handle-type unlocking device A and a panel lock-type unlocking device B. The handle-type unlocking device A and the panel lock-type unlocking device B respectively abut against a micro-switch component 7. During unlocking, either the handle-type unlocking device A or the panel lock-type unlocking device B contacts and energizes the micro-switch component 7, generating an unlocking signal that is transmitted to an electronic system for monitoring. This is achieved by setting a handle-type unlocking mechanism. The device and the panel-type unlocking device are respectively in contact with the micro switch component. When unlocking is required, the handle-type unlocking device or the panel lock-type unlocking device contacts the micro switch component and is energized to form an unlocking signal, which is transmitted to the electronic system for monitoring. This enables the system to record and control functions, and allows the electronic system to monitor the status of the door lock through detection devices, regardless of whether the emergency is triggered by the handle-type mechanical key or the key on the lock body or panel. This solves the problems of door locks not distinguishing between left and right, convenient lock tongue reversal, and door lock reliability. In smart locks, it solves the problem that in the event of an emergency, whether it is triggered by the mechanical key on the handle or the mechanical key on the lock body, the same electronic component can monitor the status of the door lock.

[0034] The handle-type unlocking device A includes: a clutch mechanism 6 located inside the cavity of the housing 1, one end of which is used to drive the locking tongue mechanism 2 to translate for unlocking;

[0035] A normally open shaft 40 is provided on the side of the inner handle 4 near the clutch mechanism 6 for rotating and driving the clutch mechanism 6 so that the locking tongue mechanism 2 translates with the clutch mechanism 6. The normally open shaft 40 is inserted into the clutch mechanism 6 and is connected to the clutch mechanism 6.

[0036] An idle shaft 50 is provided on the side of the outer handle 5 near the clutch mechanism 6 and can be connected to the clutch mechanism 6. The front end of the idle shaft 50 that is connected to the clutch mechanism 6 is provided with a square shaft 52. An idle cylinder 53 with the same diameter as the clutch mechanism 6 is provided between the idle shaft 50 and the square shaft 52. The rear end of the idle cylinder 53 is located on the idle shaft 50 and is provided with an elastic retaining spring 54 for abutting against the square shaft 52. By setting an idle cylinder with the same diameter as the inscribed circle of the clutch mechanism between the idle shaft and the square shaft, the front end of the square shaft is connected to the idle rotating sleeve assembly in the middle of the clutch mechanism, and the square shaft is fixed in a fixed position along the axial direction by the elastic retaining spring. Under the action of the outer compression spring, it always maintains the correct position with the clutch mechanism, thereby realizing that the idle shaft and the clutch mechanism cannot be directly driven, that is, idle rotation is realized.

[0037] A first locking slot 51 is provided on the outside of the outer handle 5 for unlocking the locking tongue mechanism 2;

[0038] The panel lock type unlocking device B includes: a swing arm 11; a fixed shaft 10 located in the middle of the swing arm 11 and fixed in the housing 1; and a second lock 12 for unlocking the swing arm 11. When unlocking, the lower end of the swing arm 11 rotates around the fixed shaft 10 and contacts the micro switch component 7 to generate electricity, forming an unlocking signal and transmitting it to the electronic system for monitoring.

[0039] Preferably, the clutch mechanism 6 includes a clutch sleeve 60 that abuts against one end of the locking tongue mechanism 2 for driving the locking tongue mechanism 2 to translate, a reverse lifting rotating plate 61 disposed on the clutch sleeve 60 and capable of cooperating with it, and a hollow rotating sleeve 62 fixed to the inner side of the reverse lifting rotating plate 61. The end of the normally open shaft 40 away from the handle sleeve is connected to the reverse lifting rotating plate 61. The square shaft 52 is connected to the hollow rotating sleeve 62. The clutch sleeve 60 is provided with a clutch pin 601 that can be inserted into the periphery of the hollow rotating sleeve 62. When the clutch pin 601 is away from the hollow rotating sleeve 62, the square shaft 52 and the hollow rotating sleeve 62 are relatively empty relative to the clutch sleeve 60. When the clutch pin 601 is inserted into the idler sleeve 62, the clutch sleeve 60 and the idler sleeve 62 are connected. The idler shaft 50 can drive the idler sleeve 62 to drive the clutch sleeve 60 to unlock the latch mechanism 2. The lower side of the idler sleeve 62 abuts against the micro switch component 7. By setting the clutch pin, the signal is transmitted to the motor clutch to push the clutch pin after confirmation by the electronic system outside the door. The idler sleeve assembly is connected to the external clutch sleeve to open the door, or the door can be opened by driving the clutch pin with a mechanical emergency key. This design structure realizes the problem of left and right door opening of the smart lock without using any accessories or disassembly parts.

[0040] When the unlocking component is inserted into the first lock opening 51 and rotated, the empty rotating sleeve 62 contacts the micro switch component 7 and is energized, forming an unlocking signal and transmitting it to the electronic system for monitoring.

[0041] Preferably, the idler sleeve 62 is fitted with a toothed plate 620 for emergency unlocking. The idler sleeve 62 has a corresponding guide groove for the toothed plate 620 to reciprocate. A limiting groove 602 is formed on the lower side of the clutch sleeve 60 corresponding to the guide groove. During unlocking, the toothed plate 620 moves downwards and abuts against the limiting groove 602. The idler shaft 50 is integrated with the idler sleeve 62 and the clutch sleeve 60. The toothed plate 620 in the idler sleeve 62 drives the clutch sleeve 60 to unlock the latch mechanism 2. The toothed plate 620 moves downwards and contacts the microswitch component 7, energizing it and generating an unlocking signal that is transmitted to the electronic system for monitoring. By setting the toothed plate, based on the three-body design where the handle is not divided into left and right sides, the toothed plate adopts a unique single-tooth structure design. During the key's rotation in the first lock slot, the toothed plate rotates, thus pushing it to move intermittently. During movement, due to the elastic spring on the idler shaft, the square shaft at the end of the idler shaft always presses against the toothed plate, ensuring its flexibility. The positioning is excellent, and because the toothed plate adopts a floating design that can move along the axial direction of the normally open shaft and the idle shaft, it can ensure the connection strength between the idle shaft and the idle rotating sleeve assembly. After the toothed plate moves out, it abuts against the limit groove, and the idle shaft is integrated with the idle rotating sleeve assembly and the clutch sleeve. Rotating the idle shaft can pull the lock tongue mechanism and the lock head mechanism to reset, thereby realizing the door opening with the handle-type emergency key. At the same time, the toothed plate pushes the spring on the micro switch to swing. When the micro switch spring swings, it presses the contact switch to close and energize. The micro switch component transmits the emergency unlocking signal of the mechanical key to the control electronic system, thereby realizing the system's recording and control functions. When the mechanical key is unlocked in the emergency, it reverses, the clutch pin pops out, the toothed plate resets, the idle rotating sleeve assembly separates from the clutch sleeve, and returns to the idle state. The micro switch component also resets to the normally open state during the micro switch spring reset, realizing the door locking. The toothed plate is a dual-function component that serves as both an emergency transmission component and a trigger component of the micro switch component. The design is ingenious and meets the monitoring and management requirements of the electronic system.

[0042] Preferably, an elastic element 603 for resetting the clutch pin 601 is provided between the clutch pin 601 and the clutch sleeve 60, and a transmission component 8 for pushing the clutch pin 601 into the empty sleeve 62 is provided at the end of the clutch pin 601 away from the empty sleeve 62.

[0043] Preferably, the transmission assembly 8 includes a push plate 81 for pushing the clutch pin 601 and a drive member 82 for driving the push plate 81 to move, wherein the push plate 81 and the drive member 82 are connected in a transmission manner.

[0044] Preferably, the inner side of the idle shaft 50 is provided with a mechanical key 501 that can drive the toothed plate 620 to reciprocate by rotation. One end of the mechanical key 501 is inserted into the toothed plate 620, and the other end passes through the idle shaft 50 and is connected to the first lock port 51.

[0045] Preferably, the toothed plate 620 is provided with an insertion port 6201 for inserting the mechanical key 501, and a positioning guide groove 6202 provided on the lower side of the insertion port 6201 for the toothed plate 620 to slide up and down. The empty rotating sleeve 62 is provided with a limiting shaft 621 passing through the positioning guide groove 6202 for connecting the toothed plate 620 and the empty rotating sleeve 62.

[0046] Preferably, the swing arm 11 can rotate around the fixed shaft 10 to drive the transmission assembly 8 to move, the lower end of the swing arm 11 abuts against the micro switch component 7, and the upper end of the swing arm 11 is located on one side of the second lock 12.

[0047] The second lock opening 12 is provided with a paddle 120 for pushing the swing arm 11 to rotate around the fixed shaft 10. The pushing end of the swing arm 11 pushes the transmission assembly 8 to insert the clutch pin 601 into the idler sleeve 62. The paddle on the second lock opening moves the swing arm. When the lower end of the swing arm bends and swings, it drives the push plate of the transmission assembly to move linearly, thereby pushing the clutch pin to move. This makes the idler shaft, the idler core assembly, and the clutch sleeve a linkage unit, driving the clutch sleeve to rotate to realize the pull lock tongue assembly and the square tongue reset, thereby realizing the panel-type emergency key to open the door. At the same time, when the lower end of the swing arm swings, it presses the micro switch spring to swing. When the micro switch spring swings, it presses the contact switch to energize. The micro switch component transmits the panel-type key emergency unlocking signal to the control electronic system, thereby realizing the system's recording and control functions.

[0048] Preferably, a latch limiting piece 9 for limiting the clutch cover 60 is detachably provided on the other side of the contact point between the clutch cover 60 and the latch mechanism 2. The latch limiting piece 9 is fixed to the side of the clutch cover 60 away from the contact point by a fastener 90. By setting the limiting piece, the clutch cover can be limited to one side of the limiting piece to prevent the clutch cover from shifting towards the latch mechanism under the action of the latch mechanism's tension spring.

[0049] Preferably, the lock mechanism 3 includes a lock head 30 that can freely extend and retract inside and outside the housing 1, a square shaft rocker arm 31 for driving the lock head 30 to reciprocate, and a transmission plate 32 with one end connected to the square shaft rocker arm 31 and the other end abutting against the clutch sleeve 60. When the square shaft rocker arm 31 rotates, it drives the lock head 30 to move outward from the housing 1. The transmission plate 32 translates in the direction of rotation of the square shaft rocker arm 31 and abuts against the clutch sleeve 60. By setting the square shaft rocker arm to connect with the transmission plate and the lock head, the direction of the latch can be changed regardless of whether it is inside or outside. To change the latch forward, first remove the fastener, which should be 6-8mm away. Then rotate the square shaft rocker arm to push out the latch. The square shaft rocker arm will drive the transmission plate to move, thereby creating a gap between the reverse rotating plate and the transmission plate. The clutch sleeve rotates under the force of the tension spring on the latch assembly until the clutch sleeve touches the latch limiting plate and stops. At this time, the latch will pop out of the housing. Due to the obstruction of the front plate of the lock housing, the auxiliary tongue remains inside the front plate, while the bevel latch completely leaves the front surface of the front plate. At this point, manually twist the bevel latch and auxiliary tongue together 180 degrees to the desired direction. Then, reverse the square shaft lever to retract the lock head. The square shaft lever will drive the transmission plate to move. The movement of the transmission plate will abut against the reverse lifting rotating plate, causing the clutch sleeve to rotate. At this point, the lock tongue assembly needs to be pressed into the lock body a suitable distance. Finally, tighten the fastener back into the lock body. The fastener fixes the lock tongue limiting plate and keeps it in contact with the clutch sleeve. The lock tongue reversal is now complete. This design is fundamentally different from the traditional method of using a compression spring to push the lock tongue assembly out from the tail end for reversal. The previous solutions used on the market were prone to quality problems such as the bevel latch not being able to reach the correct position after the spring deformed or broke, or the door not being able to open after the bevel latch popped out of the housing. Because the design eliminates the rear spring, the clutch sleeve and the lock tongue assembly are rigidly connected, so there will be no problem of the lock tongue assembly not reaching the correct position when opening the door.

[0050] 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.
