Description

Technical Field

[0001] This invention relates to the field of door lock technology, specifically to a door lock control method and a smart door lock. Background Technology

[0002] In the past, door locks had simple structures, such as bolt locks or security door locks, which mainly relied on keys for locking and unlocking. With social progress and development, the structure and performance of door locks improved, leading to the emergence of smart locks. However, due to the limitations of the original lock structure and size, replacing them with more convenient fully automatic locks (which can intelligently control the extension and retraction of the main bolt and the latch bolt) is almost impossible. Currently available locks that can replace these types of locks are all semi-automatic, meaning they cannot independently control the extension and retraction of the latch bolt. In other words, although the lock can be unlocked via sensors, the unlocking process involves retracting both the main bolt and the latch bolt simultaneously, and the latch bolt cannot be controlled independently, failing to provide a truly convenient and user-friendly lock experience. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a door lock control method and a smart door lock.

[0004] The present invention discloses a door lock control method, comprising: an unlocked state: a first power drives forward to retract the main bolt and the oblique bolt, and then the first power drives in reverse to form a first clutch space with the main bolt, and the first power drives in reverse to extend the oblique bolt; the first power can drive forward again to retract the oblique bolt, and since the first power is output in the first clutch space, the main bolt is still in the retracted state.

[0005] Locked state: The first power reverses to extend the main bolt, and then the first power drives forward to form a first engagement space with the main bolt. Since there is a second engagement space between the first power and the oblique bolt, the oblique bolt will remain extended.

[0006] According to one embodiment of the present invention, it further includes: unlocked state: the second power alone drives the oblique locking tongue to retract, while the first power and the main locking tongue remain in their original states.

[0007] According to one embodiment of the present invention, it further includes: unlocked state: the second power drives the main bolt to extend and change to the locked state, and the first power maintains its original state based on the existence of the first clutch space.

[0008] According to one embodiment of the present invention, it further includes: a locked state: the second power drives the main bolt and the oblique bolt to retract and switch to an unlocked state, and the first power maintains its original state based on the existence of the first clutch space.

[0009] According to one embodiment of the present invention, the output stroke of the first power in the second clutch space is twice the output stroke of the first power in the first clutch space.

[0010] The present invention discloses an intelligent door lock, comprising: using the door lock control method described above.

[0011] According to one embodiment of the present invention, it further includes:

[0012] Lock housing assembly;

[0013] The main bolt assembly is movably located within the lock housing assembly;

[0014] The angled latch assembly is movably located within the lock housing assembly;

[0015] A power assembly, located within the lock housing assembly, includes a power component, a main drive component, a secondary drive component, and a lock cylinder component. The output end of the power component is connected to the input end of the main drive component, and the output end of the main drive component is connected to the input ends of both the secondary drive component and the lock cylinder component. The lock cylinder component drives the main bolt assembly to perform locking and unlocking actions, and the secondary drive component drives the angled bolt assembly to perform locking and unlocking actions. A control assembly, located within the lock housing assembly and electrically connected to the power component, is also included.

[0016] According to one embodiment of the present invention, the auxiliary transmission component includes a first auxiliary transmission gear set, a second auxiliary transmission gear set, and an auxiliary rocker arm. The input end of the first auxiliary transmission gear set is connected to the main transmission component, and its output end is connected to the second auxiliary transmission gear set. The output end of the second auxiliary transmission gear set drives the auxiliary rocker arm to swing, and the swing of the auxiliary rocker arm drives the inclined locking tongue assembly to perform the opening and closing locking action.

[0017] According to one embodiment of the present invention, the second set of transmission gears includes a second set of gear shafts, a third set of gear bodies, and a first set of protrusions. The third set of gear bodies is sleeved on the second set of gear shafts, and the first set of protrusions is disposed on the third set of gear bodies. The inner ring of the auxiliary rocker arm has a second set of protrusions. When the power assembly drives the auxiliary rocker arm to perform the switching and locking action, the first set of protrusions abuts against the second set of protrusions and pushes the second set of protrusions to rotate, thereby causing the auxiliary rocker arm to swing.

[0018] According to one embodiment of the present invention, the inclined locking tongue assembly includes an inclined locking tongue member, a first baffle member, a second baffle member, and an elastic member. The inclined locking tongue member is movably disposed within the lock housing assembly and includes an inclined locking rod and an inclined locking tongue. One end of the inclined locking rod is connected to the first baffle member, and the other end extends along the inner surface of the lock housing assembly, passes through the second baffle member, and is connected to one end of the inclined locking tongue. The other end of the inclined locking tongue extends out of the lock housing assembly. The elastic member is sleeved on the inclined locking rod and is located between the second baffle member and the inclined locking tongue. The output end of the auxiliary swing rod swings between the first baffle member and the second baffle member.

[0019] The beneficial effects of this invention are as follows: by setting the first clutch space and the second clutch space, multiple working combinations can be formed between the main latch and the oblique latch. Especially in the unlocked state, the oblique latch can be controlled independently, that is, the oblique latch can be controlled to extend and retract, which enhances the flexibility of oblique latch control and provides users with a more convenient and easy door lock.

Furthermore, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0047] Furthermore, in this invention, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the invention. They are merely used to distinguish components or operations described using the same technical terms, and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, such a combination should be considered nonexistent and not within the scope of protection claimed by this invention.

[0048] Example 1

[0049] A door lock control method includes an unlocked state and a locked state. In the unlocked state, the main bolt is retracted, and the latch bolt can be either retracted or extended. In the locked state, both the main bolt and the latch bolt are extended. The two states will be described in detail below:

[0050] Unlocking state: Initially, the main bolt and the oblique bolt are extended. The movement of the main bolt and the oblique bolt is achieved by applying a first power. The first power driving in the forward direction will cause the main bolt and the oblique bolt to retract. Then the first power will drive in the reverse direction, creating a first engagement space between them and the main bolt. Based on the first power driving in the reverse direction, the oblique bolt will change from retracted to extended. If it is necessary to retract the oblique bolt later, the first power will drive in the forward direction again and retract the oblique bolt. As for the main bolt, due to the existence of the first engagement space, the first power will not drive the main bolt to extend when it drives in the forward direction again, thus realizing the independent control of the oblique bolt's retraction and extension.

[0051] Locked State: When the door needs to be locked after closing, the first power drive is reversed. After passing through the first clutch space, the first power will drive the main bolt to extend, thus locking. Afterward, the first power will drive forward, so that the first clutch space will reappear between it and the main bolt. There is a second clutch space between the first power and the oblique bolt. It is based on the existence of the second clutch space that the oblique bolt will remain extended during the extension of the main bolt.

[0052] Furthermore, in the unlocked state: a second power source exists, which can independently drive the oblique bolt to retract. At this time, the first power source and the main bolt maintain their original states. In other words, the process of the second power source driving the oblique bolt does not affect or interfere with the first power source and the main bolt. Additionally, the second power source can also drive the main bolt to extend, changing it from the unlocked state to the locked state. In this case, due to the existence of the first clutch space, the movement of the main bolt will not affect the first power source; that is, the first power source maintains its original state.

[0053] Furthermore, in the locked state: a second power source can be added. The second power source will drive the main bolt and the oblique bolt to retract and thus switch to the unlocked state. Based on the existence of the first clutch space, when the second power source drives the main bolt to retract, it will not affect the first power source, that is, the first power source will remain in its original state.

[0054] It should also be noted that the first clutch space is smaller than the second clutch space, that is, the output or transmission stroke of the first power in the second clutch space is greater than the output or transmission stroke of the first power in the first clutch space. In this embodiment, the output or transmission stroke of the first power in the second clutch space is twice the output or transmission stroke of the first power in the first clutch space. In this way, the difference in driving the main lock tongue and the oblique lock tongue by the first power can be realized, which also realizes the effect that the first power can drive the oblique lock tongue alone while keeping the main lock tongue unchanged.

[0055] Specifically, the first power source can be the force generated by the user's fingerprint recognition outside the door, which drives the components to operate. For example, the force output by the motor to the main latch and the angled latch serves as the first power source. The second power source is the force generated outside the door by inserting and turning the key. For example, after inserting the key outside the door, turning it in a specified direction will exert force on the main latch and the angled latch, thereby driving them to move. Due to the existence of the first and second clutch spaces, the second and first power sources do not affect each other when they operate independently. Furthermore, there is also a third power source located inside the door. This means that the user inside the door can input force to the main latch and the angled latch through a rotating component. In other words, the user can also output force to the main latch and the angled latch from inside the house, thus achieving the effect of unlocking the door from inside. Similarly, the output of the third power source does not affect the first power source.

[0056] In summary, by setting up the first and second clutch spaces, multiple working combinations can be formed between the main bolt and the angle bolt. Especially in the unlocked state, the angle bolt can be controlled independently, that is, the extension and retraction of the angle bolt can be controlled, which enhances the flexibility of the angle bolt control and provides users with a more convenient and easy door lock.

The power assembly 4 is disposed within the lock housing assembly 1 and will serve as the first power source. The power assembly 4 includes a power component 41, a main transmission component 42, a secondary transmission component 43, and a lock cylinder component 44. The output end of the power component 41 is connected to the input end of the main transmission component 42. The output end of the main transmission component 42 is connected to the input end of the secondary transmission component 43 and the input end of the lock cylinder component 44, respectively. The lock cylinder component 44 drives the main bolt assembly 2 to perform the locking and unlocking action, and the secondary transmission component 43 drives the slanted bolt assembly 3 to perform the locking and unlocking action. The control assembly 5 is disposed within the lock housing assembly 1 and is electrically connected to the power component 41.

[0059] Meanwhile, a main bolt assembly 2 and a slanted bolt assembly 3 are set in the smart door lock, and a control assembly 5 is set to control the output of the power assembly 4. The power assembly 4 drives the main bolt assembly 2 and the slanted bolt assembly 3 to perform the locking and unlocking actions, so that the smart door lock can automatically open the main bolt assembly 2 and the slanted bolt assembly 3, making it more convenient and flexible to use and meeting the user's needs.

The drive gear 412 is located at the drive end of the power unit 411. The control component 5 drives the power unit 411 to work, and the power unit 411 drives the drive gear 412 to rotate, which in turn drives the main transmission component 42 to rotate. In specific applications, the power unit 411 is a servo motor, and the drive gear 412 is a gear.

[0063] Reference Figures 2-6 , Figure 5 This is a schematic diagram of the power component in the embodiment.

The outer diameter of the fourth main gear body 4232 is larger than the outer diameter of the third main gear body 4223 and the outer diameter of the fifth main gear body 4233. In this embodiment, the fourth main gear body 4232 and the fifth main gear body 4233 are both gears. The fourth main transmission gear set 424 includes a fourth main gear shaft 4241 and a sixth main gear body 4242 and a seventh main gear body 4243 sleeved on the fourth main gear shaft 4241. The two ends of the fourth main gear shaft 4241 are connected to the upper power housing 45 and the lower power housing 46, respectively. The sixth main gear body 4242 is connected to the seventh main gear body 4243 and meshes with the fifth main gear body 4233. The outer diameter of the sixth main gear body 4242 is larger than the outer diameters of the fifth main gear body 4233 and the seventh main gear body 4243. In this embodiment, the sixth main gear body 4242 and the seventh main gear body 4243 are both gears. The fifth main transmission gear set 425 includes an eighth main gear body 4251 and a ninth main gear body 4252.

In this embodiment, both the tenth main gear body 4261 and the eleventh main gear body 4262 are gears.

[0065] The power unit 411 rotates, driving the drive gear 412 to rotate. The drive gear 412 meshes with the first main gear 4212, causing the first main gear 4212 to rotate. Simultaneously, the rotation of the first main gear 4212 drives the rotation of the second main gear 4222, which in turn drives the rotation of the third main gear 4223. The rotation of the third main gear 4223 then drives the rotation of the fourth main gear 4232, which in turn drives the rotation of the fifth main gear 4233. The drive unit 411 synchronously drives the sixth main gear 4242 to rotate, which in turn drives the seventh main gear 4243 to rotate, which in turn drives the eighth main gear 4251 to rotate, which in turn drives the ninth main gear 4252 to rotate, which in turn drives the tenth main gear 4261 to rotate, and so on. In other words, power is sequentially transmitted from the power unit 411 to the drive gears. 412, First main gear 4212, Second main gear 4222, Third main gear 4223, Fourth main gear 4232, Fifth main gear 4233, Sixth main gear 4242, Seventh main gear 4243, Eighth main gear 4251, Ninth main gear 4252, Tenth main gear 4261, and Eleventh main gear 4262. Finally, the eleventh main gear 4262 transmits power to the auxiliary transmission component 43 and the lock cylinder component 44. Through multiple stages of small gears driving the large gear, the power assembly 4 as a whole... The rotational speed is reduced. In addition, within a limited space, multiple sets of gears are relatively independently arranged on the same shaft, and the gears transmit power relatively independently between the third main gear shaft 4231 and the fourth main gear shaft 4241. In this embodiment, the power is transmitted in an "S" shape, and the power is transmitted crosswise between the third main gear shaft 4231 and the fourth main gear shaft 4241. In this way, not only can the effect of reducing speed and increasing torque be achieved, but the overall space occupied can also be reduced, making it suitable for products with smaller spaces and improving its compatibility.

The secondary transmission component 43 includes a first secondary transmission gear set 431, a second secondary transmission gear set 432, and a secondary rocker arm 433. The input end of the first secondary transmission gear set 431 is connected to the main transmission component 42, and its output end is connected to the second secondary transmission gear set 432. The output end of the second secondary transmission gear set 432 drives the secondary rocker arm 433 to swing, and the swing of the secondary rocker arm 433 drives the oblique locking tongue assembly 3 to perform the opening and closing locking action.

[0067] The first set of transmission gears 431 includes a first set of gear shafts 4311 and a first set of gear bodies 4312 and a second set of gear bodies 4313 sleeved on the first set of gear shafts 4311. The two ends of the first set of gear shafts 4311 are connected to the upper power housing 45 and the lower power housing 46, respectively. The first set of gear bodies 4312 meshes with the eleventh main gear body 4262. The first set of gear bodies 4312 and the second set of gear bodies 4313 are connected, and the outer diameter of the first set of gear bodies 4312 is larger than the outer diameter of the eleventh main gear body 4262 and the outer diameter of the second set of gear bodies 4313. In this embodiment, both the first set of gear bodies 4312 and the second set of gear bodies 4313 are gears. The second set of transmission gears 432 includes a second set of gear shafts 4321, a third set of gear bodies 4322, and a first set of protrusions 4323. The third set of gear bodies 4322 is sleeved on the second set of gear shafts 4321 and meshes with the second set of gear bodies 4313. The first set of protrusions 4323 is provided on the third set of gear bodies 4322. The inner ring of the secondary rocker arm 433 has a second set of protrusions 4331. The second set of protrusions 4331 is partially provided inside the inner ring of the secondary rocker arm 433. That is, the second set of protrusions 4331 is not completely provided around the circumference of the inner ring of the secondary rocker arm 433, but is only partially provided around the circumference of the inner ring of the secondary rocker arm 433. For example, the second set of protrusions 4331 is only provided around one-fifth or one-sixth of a circle. In this embodiment, the second set of protrusions 4331 is provided around one-sixth of a circle. A secondary rotation area 4332 for the first secondary protrusion 4323 to rotate is provided on the circumference of the inner ring of the secondary rocker arm 433. The secondary rotation area 4332 serves as a second clutch space, facilitating independent control of the oblique locking tongue assembly 3 to perform the locking and unlocking actions. It also facilitates the manual unlocking assembly 7 to drive the oblique locking tongue assembly 3 to perform the unlocking action after the third gear 4322 stops rotating. If the second secondary protrusion 4331 is cut to complete a full circle along the inner ring of the secondary rocker arm 433, leaving only the insertion position of the first secondary protrusion 4323, it is impossible to independently control the oblique locking tongue assembly 3 to perform the locking and unlocking actions, nor is it possible to drive the oblique locking tongue assembly 3 to perform the unlocking action after the third gear 4322 stops rotating, which would cause great inconvenience in use. When the power assembly 4 drives the secondary rocker arm 433 to perform the unlocking action, the first secondary protrusion 4323 abuts against the second secondary protrusion 4331 and pushes the second secondary protrusion 4331 to rotate, thereby causing the secondary rocker arm 433 to swing. The rotation of the eleventh main gear 4262 drives the first auxiliary gear 4312 to rotate, the rotation of the first auxiliary gear 4312 drives the second auxiliary gear 4313 to rotate, the rotation of the second auxiliary gear 4313 drives the third auxiliary gear 4322 to rotate, and the rotation of the third auxiliary gear 4322 drives the first auxiliary protrusion 4323 to abut against the second auxiliary protrusion 4331, and pushes the second auxiliary protrusion 4331 to rotate, thereby driving the auxiliary rocker arm 433 to swing.

[0068] Please refer to the following: Figures 8-11 , Figure 8This is a schematic diagram of the main bolt assembly, lock cylinder, and main sensing assembly in the embodiment. Figure 9 This is an exploded view of the lock cylinder and manual lever components in the embodiment. Figure 10 This is one of the structural schematic diagrams of the lock cylinder component in the embodiment. Figure 11 This is the second structural schematic diagram of the lock cylinder component in the embodiment. The lock cylinder component 44 includes a main output tooth body 441, a lock cylinder part 442, and a main rocker arm part 443. The main output tooth body 441 meshes with the eleven main tooth bodies 4262. The main output tooth body 441 and the main rocker arm part 443 are respectively sleeved on the lock cylinder part 442. The output end of the main rocker arm part 443 extends to and connects to the main latch assembly 2. The main output tooth body 441 has a main protrusion 4411 on its inner ring. The main output tooth body 441 is an annular tooth body, with its inner ring being its inner ring and its outer ring being its outer ring. The outer ring of the main output tooth body 441 has teeth. The end of the lock cylinder 442 is provided with an arc-shaped platform 4421. The arc-shaped platform 4421 is partially arranged around the circumference of the lock cylinder 442. When the power assembly 4 drives the lock cylinder 44 to perform the locking and unlocking action, the main protrusion 4411 abuts against the arc-shaped platform 4421 and pushes the arc-shaped platform 4421 to rotate, thereby driving the lock cylinder 44 to rotate. The arc-shaped platform 4421 is partially arranged around the circumference of the lock cylinder 442, that is, the arc-shaped platform 4421 is not completely arranged around the circumference of the lock cylinder 442, but is arranged in a part around the circumference of the lock cylinder 442. For example, the arc-shaped platform 4421 is only arranged in half a circle or a quarter circle. In this embodiment, the arc-shaped platform 4421 is arranged in half a circle. A main rotation area 4422 with a main protrusion 4411 is provided on the circumference of the end of the lock cylinder 442. The main rotation area 4422 serves as the first clutch space, so that the lock cylinder 442 can be rotated by the manual unlocking assembly 7 after the main output tooth 441 stops rotating. If the arc-shaped platform 4421 is cut around the entire circumference of the end of the lock cylinder 442, leaving only the insertion position of the main protrusion 4411, then the lock cylinder 442 cannot be rotated by the manual unlocking assembly 7 after the main output tooth 441 stops rotating, which will cause great inconvenience in use. Figure 10 As shown, when the power assembly 4 performs the unlocking action, the eleventh main gear 4262 drives the main output gear 441 to rotate. When the main output gear 441 rotates, it simultaneously drives the main protrusion 4411 to rotate. The main protrusion 4411 abuts against the arc-shaped platform 4421 and pushes the arc-shaped platform 4421 to rotate, thereby driving the lock cylinder 442 to rotate. In this embodiment, when the lock cylinder 442 rotates clockwise, it drives the main bolt assembly 2 to perform the unlocking action; when the lock cylinder 442 rotates counterclockwise, it drives the main bolt assembly 2 to perform the locking action. Figure 11As shown, after the unlocking action is completed, the power component 4 reverses, and the main protrusion 4411 returns to the middle position of the main rotation area 4422, leaving sufficient rotation area for the arc-shaped platform 4421 to facilitate the manual unlocking component 7 to perform the locking and unlocking action, and also to facilitate the angled lock tongue component 3 to perform the locking and unlocking action independently; the manual unlocking component 7 will act as the third power source. When the manual unlocking component 7 performs the locking and unlocking action, it directly drives the lock cylinder 442 to rotate. When the lock cylinder 442 rotates, it synchronously drives the arc-shaped platform 4421 to rotate. After the locking and unlocking is completed, the operator... The manual unlocking component 7 drives the lock cylinder 442 to rotate, and the arc-shaped platform 4421 resets and rotates to a position opposite to the main protrusion 4411. By resetting the arc-shaped platform 4421 and the main protrusion 4411 to their opposite positions, sufficient rotation area is provided for the arc-shaped platform 4421. Thus, when the manual unlocking component 7 drives the lock cylinder 442 to rotate to perform the lock opening and closing action, it will not push the main protrusion 4411 to rotate, preventing the main protrusion 4411 from affecting the subsequent lock opening and closing action of the power component 4 by driving the eleven main teeth 4262 to rotate.

[0069] Furthermore, the lock cylinder 442 also includes a lock cylinder 4423, a first locking block 4424, and a second locking block 4425, with the first locking block 4424 and the second locking block 4425 respectively located on both sides of the lock cylinder 4423. The main rocker arm 443 has a first locking groove 4431 corresponding to the first locking block 4424, which engages with the first locking block 4424. Similarly, the main rocker arm 443 has a second locking groove 4432 corresponding to the second locking block 4425, which engages with the second locking block 4425. This fixes the main rocker arm 443 to the lock cylinder 4422, and the lock cylinder 4422 drives the main rocker arm 443 to rotate via the two locking blocks, resulting in better stability when the main rocker arm 443 rotates. In this embodiment, the first locking block 4424 and the second locking block 4425 have different shapes. The cross-section of the first locking block 4424 is rectangular, and the cross-section of the second locking block 4425 is semi-circular. The first slot 4431 is a rectangular slot, and the second slot 4432 is a semi-circular slot. By setting the locking blocks and slots of the same shape, assembly errors during assembly are prevented.

[0070] The main swing arm portion 443 also includes a main swing arm 4433 and a stop rod 4434. The main swing arm 4433 and the stop rod 4434 are arranged in a "V" shape. When the main swing arm portion 443 rotates, the main swing arm 4433 abuts against the main latch assembly 2. As the main swing arm portion 443 continues to rotate, the main swing arm 4433 continuously abuts against and pushes the main latch assembly 2, causing the main latch assembly 2 to perform linear movement or rotation. When the main swing arm 4433 reaches a set position, the stop rod 4434 abuts against a fixing member, causing the main swing arm portion 443 to stop rotating, thereby stopping the main swing arm 4433 from moving. It should be noted that the fixing member can be the main latch assembly 2 or a screw fixed on the lock housing assembly 1. This embodiment does not impose specific limitations and can be selected according to actual application. Preferably, the stop rod 4434 is also connected to a spring (not shown in the figure). When the stop rod 4434 abuts against the fixing member, the spring maintains a pushing force on the stop rod 4434, making the contact between the stop rod 4434 and the fixing member more secure and effectively preventing the stop rod 4434 from reversing.

[0071] The main locking bolt assembly 2 includes a main connecting member 21 and a main locking bolt member 22. The main connecting member 21 is disposed on the outer wall of the power lower housing 46. One end of the main locking bolt member 22 is connected to the main connecting member 21, and the other end extends out of the lower housing 12. The main connecting member 21 includes a first connecting plate 211, a second connecting plate 212, and a limiting post 213. One side of the first connecting plate 211 is fixedly disposed on the outer wall of the power lower housing 46, and the second connecting plate 212 is movably disposed on the other side of the first connecting plate 211. The second connecting plate 212 has a transmission groove 2121 and a limiting groove 2122. The limiting post 213 is fixedly disposed on the first connecting plate 211 and located in the limiting groove 2122. The limiting groove 2122 can move relative to the limiting post 213. When the main locking bolt assembly 2 performs the locking / unlocking action, the limiting post 213 slides relative to the limiting groove 2122. The output end of the main swing rod 4433 moves within the transmission groove 2121 and abuts against the inner wall of the transmission groove 2121. The opening of the transmission groove 2121 is provided with a bevel 21211, and the inclination angle of the bevel 21211 is adapted to the structure and swing arc of the main swing rod 4433. When the main swing rod 4433 pushes the main locking tongue assembly 2 to the set position, the end face of the main swing rod 4433 directly abuts against the bevel 21211. The main swing rod 4433 supports the bevel 21211 and forms a stop structure, increasing the contact area between the main swing rod 4433 and the main locking tongue assembly 2, and improving the force exerted by the main swing rod 4433 on the main locking tongue assembly 2, effectively preventing the main locking tongue assembly 2 from swinging and / or moving in the opposite direction. Specifically, the transmission groove 2121 has two inclined sides 21211, which are on the same horizontal line. When the main rocker arm 4433 pushes the main locking tongue assembly 2 to lock, the main rocker arm 4433 abuts against one inclined side 21211. Conversely, when the main rocker arm 4433 pushes the main locking tongue assembly 2 to unlock, the main rocker arm 4433 abuts against the other inclined side 21211. When unlocking, the main rocker arm 4433 and the other inclined side 21211 also form a stop structure to prevent the main locking tongue assembly 2 from moving in the opposite direction.

[0072] The angled locking tongue assembly 3 includes an angled locking tongue 31, a first baffle 32, a second baffle 33, and an elastic member 34. The angled locking tongue 31 is movably disposed within the lock housing assembly 1 and includes an angled locking rod 311 and an angled locking tongue 312. One end of the angled locking rod 311 is connected to the first baffle 32, and the other end extends along the inner surface of the lock housing assembly 1, passes through the second baffle 33, and is connected to one end of the angled locking tongue 312. The other end of the angled locking tongue 312 extends out of the lock housing assembly 1. The elastic member 34 is sleeved on the angled locking rod 311 and is located between the second baffle 33 and the angled locking tongue 312. The output end of the auxiliary swing rod 433 swings between the first baffle 32 and the second baffle 33.

[0073] When the power assembly 4 drives the auxiliary rocker arm 433 to perform the unlocking action, the first auxiliary protrusion 4323 abuts against the second auxiliary protrusion 4331 and pushes the second auxiliary protrusion 4331 to rotate, thereby causing the auxiliary rocker arm 433 to swing towards the first baffle 32. The output end of the auxiliary rocker arm 433 abuts against the first baffle 32 and pushes the first baffle 32 to move away from the second baffle 33. During the movement, the oblique locking tongue 312 compresses the elastic element 34. When the elastic element 34 is fully compressed, the auxiliary rocker arm 433 stops swinging, the oblique locking tongue 312 retracts into the lower shell 12, and the oblique locking tongue 312 is unlocked. The power assembly 4 drives the auxiliary rocker arm 433 to perform the locking action. When the first protrusion 4323 rotates away from the second protrusion 4331, no external force compresses the elastic element 34. The elastic element 34 resets and pushes the oblique locking tongue 312 away from the second baffle 33, thereby causing the oblique locking rod 311 and the first baffle 32 to move synchronously. The movement of the first baffle 32 pushes the auxiliary swing rod 433 towards the second baffle 33. When the auxiliary swing rod 433 abuts against the second baffle 33, the auxiliary swing rod 433 stops swinging, and the oblique locking tongue 312 extends into the lower shell 12, locking the oblique locking tongue 312 into place. At this time, the elastic element 34 applies a force to the oblique locking tongue 312 away from the second baffle 33. During the locking and unlocking process, the second baffle 33 limits the movement of the oblique locking tongue 31. In this embodiment, the elastic element 34 is a spring.

[0074] When both the main latch assembly 2 and the oblique latch assembly 3 are in the unlocked state, the main latch 22 and the oblique latch 312 retract into the lower housing 12. When the power assembly 4 reverses and drives the main protrusion 4411 to reset, it drives the main output tooth 441 and the third auxiliary tooth 4322 to rotate in the unlocking direction. When the first auxiliary protrusion 4323 rotates away from the second auxiliary protrusion 4331, as long as the first auxiliary protrusion 4323 no longer abuts against the second auxiliary protrusion 4331, the oblique latch 312 can extend out of the lower housing 12 under the action of the elastic element 34, and the oblique latch 312 is locked in place. When component 4 stops driving, the main protrusion 4411 is still rotating in the main rotation area 4422, so it will not drive the main bolt assembly 2 to perform the locking action. The power component 4 rotates forward, driving the first auxiliary protrusion 4323 to abut against the second auxiliary protrusion 4331 and pushing the second auxiliary protrusion 4331 to rotate, thereby driving the oblique bolt 312 to retract into the lower shell 12. The oblique bolt 312 is unlocked and in place. Thus, in the unlocked state, the opening and closing of the oblique bolt assembly 3 can be controlled independently. The smart door lock has different control modes, which are more convenient and flexible to use, and meet the user's needs.

[0075] In this embodiment, the control component 5 is a PCB board.

[0076] Rereference Figure 2 as well as Figure 8 The smart lock also includes a main sensing component 6, which is adjacent to the lock cylinder 442. The main sensing component 6 includes a main sensing tooth 61 and a main sensing element 62. The main sensing tooth 61 is connected to the main sensing element 62, and the main sensing element 62 is electrically connected to the control component 5. The lock cylinder 442 also includes a detection tooth 4426, which is partially arranged along the circumference of the lock cylinder 4422 and engages with the main sensing tooth 61.

[0077] When the lock cylinder 4422 rotates, it synchronously drives the detection teeth 4426 to rotate. When the detection teeth 4426 rotates, it synchronously drives the main sensing teeth 61 to rotate. Since the main sensing teeth 61 and the detection teeth 4426 rotate at the same angle, and the detection teeth 4426 and the main swing arm 443 rotate synchronously, the main sensing element 62 only needs to collect the rotation angle information of the detection teeth 4426 to obtain the rotation angle information of the main swing arm 443. In this way, it can obtain the displacement of the main swing arm 443 pushing the main bolt assembly 2, and finally achieve precise control of the movement of the main bolt assembly 2. This avoids the phenomenon that the power component 4 continues to drive after the main bolt assembly 2 has been locked or unlocked, thus avoiding the collision of the main bolt assembly 2 and improving the stability and service life of the door lock.

[0078] Please refer to the following: Figure 12 , Figure 12 This is a schematic diagram of the oblique locking tongue assembly, secondary transmission component, control component, and secondary sensing component in the embodiment. The smart door lock also includes a manual unlocking component 7, which includes a knob 71, a manual swing lever 72, and a manual secondary swing lever 73. One end of the knob 71 is rotatably disposed outside the lock housing assembly 1, and the other end is inserted into the manual swing lever 72. The manual swing lever 72 is connected to the manual secondary swing lever 73. The manual secondary swing lever 73 is sleeved on the second secondary gear shaft 4321, with one end movably connected to the manual swing lever 72, and the other end swinging between the first baffle 32 and the second baffle 33.

[0079] The manual auxiliary rocker arm 73 includes a manual auxiliary rocker arm 731 and a torsion spring 732. The manual auxiliary rocker arm 731 and the torsion spring 732 are respectively sleeved on the second auxiliary gear shaft 4321, and the manual auxiliary rocker arm 731 is connected to the torsion spring 732. The manual auxiliary rocker arm 731 is arranged in a "V" shape, with one end abutting against the manual rocker arm 72 and the other end swinging between the first baffle 32 and the second baffle 33. The torsion spring 732 acts on the manual auxiliary rocker arm 731 and applies a continuous force to the manual auxiliary rocker arm 731 to rotate towards the first baffle 32. After the power assembly 4 controls the angled locking tongue assembly 3 to unlock, the manual auxiliary rocker arm 731 will swing to the position abutting against the first baffle 32 under the action of the torsion spring 732. After the power assembly 4 controls the angled locking tongue assembly 3 to lock, the manual auxiliary rocker arm 731 will move towards the second baffle 33 and abut against the second baffle 33 under the push of the first baffle 32. In this embodiment, the force exerted by the torsion spring 732 on the manual auxiliary lever 731 is less than the force exerted by the elastic element 34 when it is reset.

[0080] Reference Figures 12-15 , Figure 13 This is one of the structural schematic diagrams of the lock cylinder and manual unlocking assembly in the embodiment. Figure 14 This is the second structural schematic diagram of the lock cylinder and manual unlocking assembly in the embodiment. Figure 15 This is a cross-sectional view of the lock cylinder and manual unlocking assembly in the embodiment. The knob 71 includes a knob 711 and a rotating rod 712. One end of the rotating rod 712 is connected to the knob 711, and the other end is inserted into the manual swing lever 72. When unlocking, the knob 711 is manually rotated, thereby driving the rotating rod 712 to rotate. The rotation of the rotating rod 712 drives the manual swing lever 72 to rotate. The rotating manual swing lever 72 abuts against the lock cylinder 44 and the manual auxiliary swing lever 731, and pushes the lock cylinder 44 and the manual auxiliary swing lever 731 to rotate, thereby performing the unlocking action.

[0081] The manual lever assembly 72 includes a connecting cylinder 721 and a manual lever 722. The connecting cylinder 721 is inserted into the lock cylinder 44 and is located between the knob 711 and the lock cylinder 44. The end of the connecting cylinder 721 away from the lock cylinder 44 is connected to the manual lever 722. When the rotating rod 712 rotates, it drives the connecting cylinder 721 to rotate, thereby driving the manual lever 722 to rotate synchronously.

[0082] The manual auxiliary rocker arm 731 includes a transmission rod 7311 and an auxiliary rocker arm 7312. The transmission rod 7311 and the auxiliary rocker arm 7312 are arranged in a "V" shape. One end of the transmission rod 7311 is connected to the auxiliary rocker arm 7312. The manual rocker arm 722 acts on the other end of the transmission rod 7311 and drives the transmission rod 7311 to rotate away from the lock cylinder 44. At the same time, the auxiliary rocker arm 7312 rotates towards the lock cylinder 44 to drive the oblique lock tongue assembly 3 to perform the unlocking action.

[0083] The torsion spring 732 acts on the auxiliary rocker arm 7312, causing it to rotate towards the lock cylinder 44. When the smart lock changes from the locked state to the unlocked state, no other components abut against the manual auxiliary rocker arm 731. Driven by the torsion spring 732, the manual auxiliary rocker arm 731 swings from the locked position to the unlocked position to facilitate subsequent locking and unlocking actions.

[0084] The lock cylinder 442 has a mounting groove 4428 and a first key groove 4429, which are connected. The connecting cylinder 721 is located in the mounting groove 4428. The end of the lock cylinder 442 away from the connecting cylinder 721 is connected to a keyhole (not shown in the figure). The user can use the key 100 to manually unlock the lock through the keyhole, where the key serves as a secondary power source.

[0085] The end of the lock cylinder 442 is also provided with a rotating groove 4427, in which the manual lever 722 rotates. The rotating groove 4427 is partially provided along the circumference of the lock cylinder 442. In this embodiment, the rotating groove 4427 is provided in a semi-circumference along the circumference of the lock cylinder 442, providing a rotation area for the manual lever 722. When the manual lever 722 rotates in the rotating groove 4427, it will not abut against the lock cylinder 442, that is, it will not drive the lock cylinder 442 to rotate. However, when the manual lever 722 rotates in the rotating groove 4427, it can abut against the transmission rod 7311 and drive the transmission rod 7311 to rotate away from the lock cylinder 44. At the same time, the auxiliary lever 7312 rotates towards the lock cylinder 44 to drive the oblique bolt assembly 3 to perform the unlocking action, thereby independently controlling the oblique bolt assembly 3.

[0086] The connecting cylinder 721 has a second key slot 7211 and two second abutment blocks 7212 inside. The second key slot 7211 communicates with the first key slot 4429, and the two second abutment blocks 7212 are disposed opposite each other on the inner wall of the second key slot 7211. The rotating rod 712 extends into the second key slot 7211 and acts on the opposite sides of the two second abutment blocks 7212, thereby rotating the connecting cylinder 721. When the connecting cylinder 721 rotates, it drives the manual rocker arm 722 to rotate. When the manual rocker arm 722 rotates in the rotating groove 4427, it drives the oblique locking tongue assembly 3 to perform the unlocking action. If the rotary knob 71 is rotated at this time, the manual rocker arm 72 and the manual auxiliary rocker arm 731 will also rotate synchronously, and the oblique locking tongue assembly 3 will perform the locking action. If the knob 71 is turned after the oblique bolt assembly 3 has performed the unlocking action, the manual lever 722 will abut against the side wall of the rotating groove 4427, thereby abutting against the lock cylinder 442 and driving the lock cylinder 442 to rotate. The rotation of the lock cylinder 442 will drive the external main bolt assembly 2 to perform the unlocking action. That is, the knob 71 can control the oblique bolt assembly 3 alone, or it can control the main bolt assembly 2 and the oblique bolt assembly 3 together.

[0087] The lock cylinder 44 is also provided with two first abutting blocks 444, which are disposed opposite to each other on the inner wall of the first key groove 4429. The two first abutting blocks 444 and the two second abutting blocks 7212 are arranged alternately. When the external key 100 is used to unlock, the key 100 extends from the end of the first key slot 4429 away from the mounting slot 4428 into the first key slot 4429 and the second key slot 7211. At this time, the external key unlocking and the rotating rod 712 are interleaved. The key 100 acts on the opposite sides of the two first abutment blocks 444 and the opposite sides of the two second abutment blocks 7212. Turning the key 100 drives the lock cylinder part 442 and the manual swing rod 72 to rotate, and finally drives the main bolt assembly 2 and the oblique bolt assembly 3 to perform the unlocking action. During the rotation of the manual swing rod 72, because the key 100 and the rotating rod 712 are interleaved and the second key slot 7211 has a sufficient area, the two second abutment blocks 7212 will not drive the rotating rod 712 to rotate when the manual swing rod 72 rotates. That is, when the key 100 is used to unlock, it will not affect the rotating rod 712.

[0088] Rereference Figure 12 The smart door lock also includes a secondary sensing component 8, which includes a magnet 81 and a Hall sensor 82. The magnet 81 is located at one end of the manual secondary rocker arm 73 near the manual rocker arm 72, and the Hall sensor 82 is located on the movement path of the magnet 81 and is electrically connected to the control component 5. Preferably, there are two Hall sensors 82, one of which is located in the unlocked position of the manual secondary rocker arm 73, and the other is located in the locked position of the manual secondary rocker arm 73, thereby detecting the opening and closing status of the bolt assembly 3.

[0089] The automatic opening and closing process of a smart door lock is as follows:

[0090] When unlocking, the power component 4 rotates forward, driving the auxiliary transmission component 43 and the lock cylinder component 44 to rotate. The rotation of the auxiliary transmission component 43 causes the first auxiliary protrusion 4323 to abut against the second auxiliary protrusion 4331, and pushes the second auxiliary protrusion 4331 to rotate, thereby causing the auxiliary rocker arm 433 to swing towards the first baffle component 32. The output end of the auxiliary rocker arm 433 abuts against the first baffle component 32 and pushes the first baffle component 32 to move away from the second baffle component 33. During the movement, the oblique locking tongue 312 compresses the elastic component 34. When the elastic component 34 is fully compressed, the auxiliary rocker arm 433 stops swinging, and the oblique locking tongue 312 retracts into the lower shell component 12, and the oblique lock... The tongue 312 is unlocked; the lock cylinder 44 rotates, causing the main rocker arm 443 to rotate. When the main rocker arm 443 rotates, the main rocker arm 4433 abuts against the main tongue assembly 2. As the main rocker arm 443 continues to rotate, the main rocker arm 4433 continues to abut against and push the main tongue assembly 2, causing the main tongue assembly 2 to move linearly in the direction of retracting into the lower housing 12. At the same time, when the detection teeth 4426 rotates, it synchronously drives the main sensing teeth 61 to rotate synchronously. When the main sensing element 62 senses that the main sensing teeth 61 has reached the preset rotation angle, it controls the power element 41 to stop driving, and the main tongue assembly 4 retracts into the lock housing assembly 1, and the main tongue assembly 4 is unlocked. When locking, the power assembly 4 reverses, driving the auxiliary transmission component 43 and the lock cylinder component 44 to rotate. The rotation of the auxiliary transmission component 43 causes the first auxiliary protrusion 4323 to rotate away from the second auxiliary protrusion 4331. As long as the first auxiliary protrusion 4323 is no longer in contact with the second auxiliary protrusion 4331, the oblique locking tongue 312 can extend out of the lower shell component 12 under the action of the elastic component 34, and the oblique locking tongue 312 is locked in place. The power assembly 4 continues to reverse, and the lock cylinder component 44 rotates, driving the main swing arm 443 to rotate. When the main swing arm 443 rotates... The main rocker arm 4433 abuts against the main latch assembly 2, and as the main rocker arm 4433 continues to rotate, the main rocker arm 4433 continuously abuts against and pushes the main latch assembly 2, causing the main latch assembly 2 to move linearly in the direction of extending out of the lower housing 12. At the same time, when the detection tooth 4426 rotates, it synchronously drives the main sensing tooth 61 to rotate. When the main sensing element 62 senses that the main sensing tooth 61 has reached the preset rotation angle, it controls the power element 41 to stop driving, and the main latch assembly 4 extends out of the lock housing assembly 1, and the main latch assembly 4 is unlocked.

[0091] In summary, the smart lock of this application incorporates both a main bolt assembly and a slanted bolt assembly, and includes a control assembly to control the output of the power assembly. The power assembly drives the main bolt assembly and the slanted bolt assembly to perform locking and unlocking actions, enabling the smart lock to automatically open both the main bolt assembly and the slanted bolt assembly. Furthermore, in the unlocked state, the slanted bolt assembly can be controlled independently, making it more convenient and flexible to use and meeting the user's needs.
