[0001] This invention relates to a rotary clutch-type adjustable keyhole smart lock, belonging to the field of smart door lock technology. Background Technology

[0002] Smart locks are improvements upon traditional mechanical locks, offering greater intelligence and convenience in terms of user security, identification, and management. They free people from the reliance on keys, allowing them to open doors anytime, anywhere with just a mobile phone. However, replacing a traditional mechanical lock with a smart lock requires the complete removal and replacement of the mechanical lock, which is costly. Furthermore, some doors are not fully compatible with smart locks, compromising security. To address this, the industry has developed various related devices. For example, Chinese utility model patent CN219993417U discloses an external door lock structure, specifically including an outer door lock fitting sleeve and an inner door lock fitting sleeve. A camera assembly is fixedly installed on the top of the outer door lock fitting sleeve, and a functional plate is fixedly installed on the bottom of the outer door lock fitting sleeve. A nut slider is movably fitted onto the outer side of the slide rail, and a bearing seat is fixedly installed on the top of the slide rail. A threaded rod is provided inside the bearing seat.

[0007] The aforementioned rotary clutch adjustable smart lock has a ring at the upper end of the fourth gear, with multiple circumferentially distributed levers on the ring; a lever is rotatably connected to the second housing, located on the side of the fourth gear and cooperating with the levers; two guide posts are provided on the rotating plate, each coaxial with the second gear; a guide rail protrusion is provided on the second housing; the lower ends of the guide posts and guide rail protrusions cooperate; and an arc-shaped groove is provided on the control plate, cooperating with the guide rail protrusion.

[0008] The aforementioned rotary clutch adjustable smart lock has adhesive on the first housing and a battery inside the cavity.

[0009] The aforementioned rotary clutch adjustable smart lock has a first knob at the middle of the upper end of the fourth gear; a second knob is rotatably connected to the outside of the third housing; and the first knob passes through the second housing and is fixedly connected to the second knob.

[0010] In the aforementioned rotary clutch adjustable smart lock, the guide of the second sliding guide groove is perpendicular to the guide of the first sliding guide groove; the key connection mechanism includes clamps symmetrically arranged on the moving plate, forming a cavity between the clamps for placing the key handle; each clamp has a stop block on its outer side; a key blocking block is provided on the upper part of the clamp, and baffles are provided on both sides of the lower end of the key blocking block, with the baffles cooperating with the stop block; a key groove is provided in the middle of the key blocking block, with the key groove facing the cavity.

[0011] The aforementioned rotary clutch adjustable smart lock has a trapezoidal cross-section for the stop block, with a smaller upper end and a larger lower end; the upper surface of the stop block is flush with the upper surface of the clamping plate; the cross-section of the baffle is L-shaped; and the baffle has limiting plates on its front and rear sides respectively.

[0012] The aforementioned rotary clutch adjustable smart lock has a first protrusion on each of the lower sides of the moving block; a first groove is provided on each of the two sides of the first sliding guide groove; the first protrusion and the first groove cooperate; a second protrusion is provided on each of the two sides of the moving plate; a second groove is provided on each of the two sides of the second sliding guide groove; and the second protrusion and the second groove cooperate.

[0013] The aforementioned rotary clutch adjustable smart lock also includes a third moving guide groove on the moving block, which is located below the second sliding guide groove. The guide of the third moving guide groove is perpendicular to the guide of the second sliding guide groove. A limit block is fixedly connected to the middle of the first sliding guide groove, and the limit block is slidably connected to the third moving guide groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This invention requires first connecting the lock hole adjustment mechanism to the key. Based on the lock hole position, the moving block moves within the first sliding guide groove, and the moving plate moves within the second sliding guide groove, aligning the key with the lock cylinder. Then, the key core is inserted into the lock cylinder, and finally, the first housing is connected and fixed to the lock. When the homeowner unlocks the lock by turning the key from the outside, the clutch mechanism prevents the motor from connecting to the fourth gear, reducing resistance to opening the door. When the homeowner does not have the key, a signal is sent to the control board of this invention via a mobile phone, causing the motor to start rotating. The motor connects to the fourth gear through the clutch mechanism and drives the fourth gear to rotate, causing the key mounting mechanism on the fourth gear to rotate the key handle, achieving the unlocking effect. During the rotation of the clutch mechanism, the fifth gear rotates, which in turn drives the potentiometer's brush to rotate. This causes the potentiometer to generate different electrical signals to the control board depending on the rotation angle. The control board records these signals for easier unlocking in the future and stops the motor at the desired unlocking angle to prevent key breakage. After unlocking, the motor is disconnected from the fourth gear via the clutch mechanism.

[0016] 2. The clutch mechanism of this invention uses a motor to drive the first gear to rotate. The first gear meshes with the second gear, causing the second gear to rotate with the rotating plate until it meshes with the third gear. The second gear then drives the third gear to mesh and rotate, and the third gear in turn drives the fourth gear to mesh and rotate. This causes the key mounting mechanism on the fourth gear to rotate the key handle, achieving the unlocking effect. After unlocking, the motor reverses, causing the first and second gears to mesh and reverse. Then, the second gear rotates in the opposite direction with the rotating plate, returning the second and third gears to their disengaged state.

[0017] 3. The present invention sets a ring on the fourth gear, and the ring has pawls distributed at a certain angle, such as one pawl every 60°. This ensures that the fourth gear will contact the pawl once every 60° rotation. After the pawl is moved, it will send a signal to the control board to record the approximate rotation angle. This signal is then used to compare and correct the angle information sent by the potentiometer, thereby increasing the accuracy of the present invention.

[0018] 4. The key connection mechanism of the present invention connects the key to the present invention by placing the key handle in the cavity between the clamping plates, then passing the key core through the key groove on the key blocking block, and then connecting the baffle of the key blocking block with the baffle of the clamping plate. The limiting block and the third moving guide groove cooperate to prevent the moving block and the first sliding guide groove from falling off during sliding, thus strengthening the connection.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0027] Example: A rotary clutch-type adjustable keyhole smart lock, configured as follows Figure 1-5As shown, the lock head 2, located inside the door lock 1, includes a main body 3. The main body 3 contains a control board 4, which is a PCBA board integrating a processor and electronic components such as capacitors and resistors. The processor can be a Bluetooth chip of model TLSR8251 manufactured by Telink Microelectronics. Since the control board 4 is a common component in this field and is commercially available, the specific structure and circuit connections of the circuit board will not be described in detail here. The control board 4 has a potentiometer 5, which is also a common component available commercially. In this embodiment, the potentiometer 5 is a potentiometer of model RDC506017A manufactured by Alps Alpine. The main body 3 includes a first housing 6, which has a circular front end and a square rear end, and is made of plastic. The first housing 6 is used to fix the door lock 1. Figure 5As shown, a cavity 7 is provided on one side of the first housing 6. A motor 8 is connected to the cavity 7 via a fixed base. The output end of the motor 8 passes through the first housing 6 and is connected to a clutch mechanism 35. A fourth gear 13 and a fifth gear 15 are provided on the first housing 6. The fourth gear 13 is connected to the clutch mechanism 35. The fourth gear 13 is located at the end of the first housing 6 away from the clutch mechanism 35. A lock hole adjustment mechanism 14 is provided on the end of the fourth gear 13 facing the first housing 6. The fifth gear 15 is connected to the clutch mechanism 35 and is also connected to a potentiometer 5. The lock hole adjustment mechanism 14 includes a first gear 13 mounted on the fourth gear 13. The sliding guide groove 102 has a sliding block 103 slidably connected inside it. The sliding block 103 is square and made of plastic. The lower two sides of the sliding block 103 have first protrusions 104 respectively. The two sides of the first sliding guide groove 102 are respectively provided with first grooves 125. The first protrusions 104 cooperate with the first grooves 125. By embedding the entire sliding block 103 in the first sliding guide groove 102, the sliding block can move in the first sliding guide groove 102. At the same time, since the first protrusions 104 are embedded in the first grooves 125, the first protrusions 104 play a sliding limiting role for the sliding block 103 to prevent deviation. A movable plate 106 is slidably connected within the second sliding guide groove 105. The movable plate 106 is rectangular in shape with rounded ends and is made of plastic. Each side of the movable plate 106 has a second protrusion 107, which is elongated. Each side of the second sliding guide groove 105 has a second groove 126, with the second protrusion 107 engaging with the second groove 126. By embedding the movable plate 106 within the second sliding guide groove 105, the movable block can move within it. Simultaneously, because the second protrusion 107 is embedded within the second groove 126, it acts as a sliding limiter for the movable plate 106, preventing deviation. The guide of the second sliding guide groove 105 is perpendicular to the guide of the first sliding guide groove 102. This perpendicular arrangement allows for a large range of movement for both the movable block 103 and the movable plate 106, facilitating adjustment. The movable plate 106 is equipped with a key connection mechanism. The main body 3 also includes a second housing 16, which is located on the same side of the first housing 6 as the clutch mechanism 35; Figure 4 As shown, the control board 4 is fixedly connected to the second housing 16; the main body 3 also includes a third housing 23 disposed above the second housing 16, the third housing 23 being used to protect the components on the second housing 16. The second housing 16 and the third housing 23 have the same shape as the first housing 6 and are made of plastic. Figure 3 As shown, the upper end of the fourth gear 13 is provided with a ring 17, and the ring 17 is provided with circumferentially distributed pavers 18. The ring 17 is used to reinforce the connection between the pavers and the fourth gear 13; as Figure 4As shown, a strip-shaped paddle 19 is rotatably connected to the second housing 16. The paddle 19 is located on the side of the fourth gear 13 and engages with the paddle bar 18. In this invention, the included angle between adjacent paddle bars 18 is 60°, so that the fourth gear 13 will contact the paddle 19 once every 60° rotation. After the paddle 19 is paddled, it sends a signal to the control board 4 to record the approximate rotation angle, which is used to compare and correct the angle information sent by the potentiometer 5, thereby increasing the accuracy of this invention. Figure 3 As shown, the rotating plate 10 is provided with two cylindrical guide posts 20, which are made of stainless steel and are coaxial with the second gear 11. Figure 4 As shown, the second housing 16 is provided with a guide rail protrusion 21, the lower part of which is hollow; the guide post 20 cooperates with the lower end of the guide rail protrusion 21; the control plate 4 is provided with an arc-shaped groove 22, which cooperates with the guide rail protrusion 21. The first housing 6 is provided with adhesive 31. In this embodiment, the adhesive 31 is 3M adhesive, used to attach the present invention to the door lock 1; the cavity 7 is provided with a storage battery 32, which provides power for the operation of the present invention. The upper middle part of the fourth gear 13 is provided with a first knob 33; the outer side of the third housing 23 is rotatably connected to a second knob 34; the first knob 33 passes through the second housing 16 and is fixedly connected to the second knob 34. By turning the second knob 34, the first knob 33 is rotated, which in turn drives the fourth gear 13 to rotate, thereby turning the key handle to unlock the door. This eliminates the need to send a signal from the mobile phone to the control board 4 for unlocking from the inside of the door, and also prevents situations where the door cannot be unlocked from the inside due to a dead battery 32 or a damaged motor. The moving block 103 is also provided with a third moving guide groove 121, which is elongated and located below the second sliding guide groove 105. The guide of the third moving guide groove 121 is perpendicular to the guide of the second sliding guide groove 105. A cylindrical limiting block 123 is fixedly connected to the middle of the first sliding guide groove 102. The limiting block 123 extends into the third moving guide groove 121 and slides therewith, thus forming a limiting fit between the limiting block 123 and the third moving guide groove 121. This prevents the moving block 103 and the first sliding guide groove 102 from falling off during sliding, strengthening the connection.

[0028] Preferably, such as Figure 3As shown, the clutch mechanism 35 includes a first gear 9 disposed on the first housing 6 and connected to the output shaft of the motor 8. A rotating plate 10 is rotatably connected to the upper end of the first gear 9. A second gear 11 is respectively disposed on both sides of the first gear 9 at the lower end of the rotating plate 10. The second gear 11 meshes with the first gear 9. A third gear 12 is disposed on the first housing 6. The third gear 12 is located between the fourth gear 13 and the first gear 9, and the third gear 12 meshes with the fourth gear 13. The second gear 11 rotates with the rotating plate 10 and meshes with or separates from the third gear 12. The fifth gear 15 meshes with the third gear 12. The clutch mechanism 35 drives the first gear 9 to rotate via the motor 8. The first gear 9 meshes with the second gear 11, causing the second gear 11 to rotate with the rotating plate 10 until it meshes with the third gear 12. The second gear 11 then drives the third gear 12 to mesh and rotate, and the third gear 12 in turn drives the fourth gear 13 to mesh and rotate. This causes the key mounting mechanism on the fourth gear 13 to rotate the key handle, achieving the unlocking effect. After unlocking, the motor 8 reverses, causing the first gear 9 to mesh with the second gear 11 in reverse. Then, the second gear 11 rotates in the opposite direction with the rotating plate 10, returning the second gear 11 to its disengaged state with the third gear 12.

[0029] Preferably, such as Figure 6 As shown, the key connection mechanism 36 includes clamping plates 108 symmetrically arranged on the movable plate 106. The clamping plates 108 are rectangular in shape and made of plastic. A cavity 119 for placing the key handle is formed between the clamping plates 108. Stops 109 are provided on the outer sides of each clamping plate 108. A key blocking block 110 is provided on the upper part of each clamping plate 108. Baffles 111 are provided on both sides of the lower end of the key blocking block 110, and the baffles 111 cooperate with the stop blocks 109. A key groove 112 is provided in the middle of the key blocking block 110, and the key groove 112 faces the cavity 119. The cross-section of the stop block 109 is trapezoidal, smaller at the top and larger at the bottom. The upper surface of the stop block 109 is flush with the upper surface of the clamping plate 108. Figure 3 As shown, the baffle 111 has an L-shaped cross-section; the baffle 111 has a limiting plate 124 on its front and rear sides, which is used to prevent the baffle 111 and the stop block 109 from sliding back and forth and falling off after they are connected. After the baffle 111 and the stop block 109 are connected, the key blocking block 110 can only be removed by folding the baffle 111 outward to separate it from the stop block 109. A reinforcing plate 120 is connected to the bottom side of the clamping plate 108. The reinforcing plate 120 is also connected and fixed to the moving plate 106. The reinforcing plate 120 has an L-shaped cross-section and is used to reinforce the connection between the clamping plate 108 and the moving plate 106.

[0030] Working principle

[0031] This invention requires first connecting the lock hole adjustment mechanism 14 to the key. The key handle is placed in the cavity 119 between the clamping plates 108 of the key connecting mechanism 36. Then, the key core passes through the key groove 112 on the key blocking block 110, and the baffle 111 of the key blocking block 110 engages with the baffle 109 of the clamping plate 108 to connect the key to the invention. The key position is adjusted according to the lock head 2 position of the door lock 1. The key core is then inserted into the lock head 2 of the door lock 1. Finally, the key is connected and fixed to the door lock 1 using the adhesive 31 on the first housing 6. When the homeowner unlocks the door lock 1 by turning the key from the outside, the second gear 11 and third gear 12 of the clutch mechanism 35 are not in contact, preventing the motor 8 from rotating and reducing opening resistance. When the homeowner doesn't have their keys, they send a signal to the control board 4 of this invention via their mobile phone, causing the motor 8 to start rotating. The motor 8 drives the first gear 9 of the clutch mechanism 35 to rotate, and the first gear 9 meshes with the second gear 11, causing the second gear 11 to rotate with the rotating plate 10 until the second gear 11 meshes with the third gear 12. Then, the second gear 11 drives the third gear 12 to mesh and rotate, and the third gear 12 then drives the fourth gear 13 to mesh and rotate, causing the key mounting mechanism 14 on the fourth gear 13 to rotate and achieve the unlocking effect. During the rotation of the third gear 12, it drives the fifth gear 15 to rotate, and the fifth gear 15 drives the brush of the potentiometer 5 to rotate, so that the potentiometer 5 generates different electrical signals to the control board 4 depending on the angle of rotation. The control board 4 records this signal for easier and faster unlocking in the future, and stops the motor 8 when the unlocking angle is reached to prevent the key from breaking. After unlocking, motor 8 reverses, causing the first gear 9 to mesh and reverse with the second gear 11. Then, the second gear 11 rotates in the opposite direction with the rotating plate 10, allowing the second gear 11 and the third gear 12 to return to the separated state.
