Description

Technical Field

[0001] The present invention relates to the field of intelligent door locks, and in particular to an intelligent door lock and a method for maintaining potential energy and unlocking control thereof. Background Art

[0002] Smart door locks have significant advantages over traditional door locks in terms of security and ease of use, and are therefore deeply loved by people and are becoming more and more popular in people's daily lives. Traditional smart door locks use batteries as power supply. A smart door lock often needs to be equipped with several batteries. Under normal use, the battery life is only half a year to a year, resulting in users having to frequently replace batteries to maintain the normal operation of the smart door lock. Since the battery replacement procedures are relatively cumbersome, the ease of use of smart door locks is reduced. The attractiveness of smart door locks to people is reduced. At the same time, the huge consumption of batteries by smart door locks will correspondingly generate a large number of discarded batteries, which will inevitably cause waste of resources and environmental pollution. This is very unfriendly to environmental protection and does not conform to the current environmental protection concept advocated.

[0003] In response to this, smart locks have appeared on the market that use hand-cranked generators to charge batteries to extend the battery life. Although this type of smart lock has extended the user's battery replacement cycle to a certain extent and reduced battery consumption, the process of charging the battery through a hand-cranked generator is still very inconvenient. On the one hand, it takes a long time, and on the other hand, it requires a lot of energy from the user, which runs counter to the original intention of the smart lock to improve the convenience of use.

[0004] Therefore, under the advocacy of improving ease of use and environmental protection, smart locks using passive technology have begun to appear on the market, such as the existing hand-cranked smart locks. Specifically, the existing hand-cranked smart locks have a hand-cranked generator, and the user generates electricity by hand-cranking to accumulate the electrical energy required for the operation of the smart lock. In other words, when in use, the user needs to keep cranking the generator until the power is sufficient to unlock the lock. Obviously, although this type of passive smart lock does not require the use of batteries and avoids the environmental pollution caused by battery consumption, it requires the user to continuously drive the hand-cranked generator for a period of time before unlocking the lock during use, which is time-consuming and labor-intensive and cannot meet the user's usage needs.

[0005] The Chinese utility model patent with announcement number CN210622517U discloses a self-powered smart lock, which includes a lock arm, a generator coupled to the lock arm, a lock release assembly, at least one identity authentication module and a lock tongue, wherein the lock release assembly includes a lock release piece and a force storage piece locked by the lock release piece and linked to the lock arm, the lock tongue is coupled to the force storage piece, and when the lock arm is driven, the generator is driven to generate electrical energy, and the force storage piece is linked to the lock arm to store potential energy, and the identity authentication module is powered by the generator for identifying the user's identity. When the user's identity is authenticated to be legal, the lock release piece releases the lock of the force storage piece, the force storage piece releases the potential energy, and the lock tongue is driven by the force storage piece to unlock, so that when the user pivots the lock arm in a traditional unlocking manner, the self-powered smart lock can be unlocked in a battery-free manner, overcoming the defects of existing hand-cranked smart locks and having broad market prospects. However, the self-powered smart lock still has some defects in actual application, which affect the user experience. Specifically, the force storage member needs to rely on the linkage with the lock arm to store potential energy, resulting in that when the lock arm cancels the linkage with the force storage member, the potential energy stored in the force storage member is also released, causing the user to maintain the unlocking posture when the identity authentication module has not completed the corresponding authentication work to avoid the failure of the energy storage of the force storage member and affect the unlocking; and in the actual application process, if the user pivots the lock arm to link the generator and the electric energy generated is not enough to complete the unlocking, the user needs to pivot the lock arm again, and the force storage member will lose its stored potential energy as the linkage with the force storage member is canceled, that is, the force storage member cannot maintain the potential energy, so that every time the user pivots the lock arm, the force storage member and the lock tongue must be linked, resulting in the user each time. It is necessary to apply a heavier force to pivot the lock arm, even if the user's purpose of pivoting the lock arm is only to link the generator to generate electricity; at the same time, it is understandable that the lock release member needs to consume a certain amount of electrical energy to complete the release of the lock of the force storage member. Therefore, the potential energy stored in the force storage member is related to the electrical energy required for the lock release member. On the one hand, the smaller potential energy stored in the force storage member is beneficial to reducing the energy consumption of the lock release member, but it is very easy to cause the force storage member to fail to smoothly drive the lock tongue to unlock, resulting in the self-powered smart lock failing to successfully complete the unlocking. On the other hand, when ensuring that the force storage member can store enough potential energy to drive the lock tongue to unlock, the energy consumption of the lock release member also increases, resulting in the generator's power generation being unable to simultaneously meet the working requirements of the identity authentication module and the lock release member, which also results in the self-powered smart lock failing to successfully complete the unlocking.

[0006] That is to say, battery-powered smart locks have significant advantages in terms of security and ease of use and are deeply loved by people. However, the battery-powered method inevitably causes battery consumption, leading to environmental pollution. The passive smart locks that were created to solve the environmental pollution problem do not need to use batteries and overcome the defect of environmental pollution, but their usage method does not conform to the user's usage habits and will consume a lot of user's time and energy, which runs counter to the design concept of easy-to-use smart locks. Although the technical solution provided in the Chinese utility model patent with announcement number CN210622517U can overcome the defects of existing passive smart locks to a certain extent and has broad market prospects, the technical solution still has defects in actual application, such as unreliable unlocking and the user needing to apply heavy operating force multiple times, which need to be solved.

[0155] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, deformation schemes, improved schemes, equivalent schemes, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0158] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0159] The present invention provides a technical solution that can temporarily hold (latch) elastic potential energy and release the held elastic potential energy to unlock when unlocking is required, so that the elastic potential energy can be stably held before unlocking, thereby facilitating user operation.

[0160] Referring to the accompanying drawings of the present invention Figures 1 to 3B , a smart door lock 10 according to an embodiment of the present invention is illustrated. It is worth mentioning that the smart door lock 10 provided in this embodiment of the present invention is a self-powered smart door lock 10. Figures 1 to 3B As shown, the smart door lock 10 includes a lock handle 11, a power generation unit 12, a stepping drive unit 13, a control unit 14 and a lock core unit 15, wherein the lock handle 11 is suitable for being driven by an external force to generate a mechanical energy, and can return to its original position after the corresponding external force is removed, wherein the power generation unit 12 is linked to the lock handle 11, so that the lock handle 11 is linked to convert the mechanical energy into electrical energy when the lock handle 11 is driven, wherein the stepping drive unit 13 is linked to the lock handle 11, so that the lock handle 11 is linked to convert the mechanical energy into electrical energy when the lock handle 11 is driven. The control unit 14 is electrically connected to the power generation unit 12 to identify the identity of the user under the power supply of the power generation unit 12, wherein the lock core unit 15 is linked and coupled to the stepping drive unit 13, wherein the stepping drive unit 13 is controlled by the control unit 14 to release the potential energy. Specifically, when the control unit 14 identifies that the identity of the user is legal, the stepping drive unit 13 is controlled to release the potential energy to link the lock core unit 15 to unlock, thereby realizing the unlocking process of the smart door lock 10.

[0161] It is worth mentioning that the power generation unit 12 generates electric energy based on the lock handle 11 being driven, so that the smart door lock 10 can work without external power supply such as battery, thereby avoiding the battery consumption problem caused by using battery power, thereby avoiding environmental pollution, and can generate electric energy in conjunction with the user operating the smart door lock 10. Specifically, in this embodiment of the present invention, the lock handle 11 is driven in a pivoting manner, so that the user can pivot the lock handle in a traditional unlocking operation habit, and drive the lock handle 11 during the user's unlocking operation to link the power generation unit 12 to generate electric energy, so as to provide electric energy for the smart door lock 10 to complete the corresponding operation. Without the advantage of battery power, the ease of use of the smart door lock 10 is improved, thereby improving the environmental protection and convenience of the smart door lock 10, so as to provide a smart door lock that conforms to the user's operating habits and environmental protection design concepts.

[0162] Furthermore, the smart door lock 10 includes a transmission unit 16, wherein the transmission unit 16 is respectively coupled to the lock handle 11 and the power generation unit 12, and the lock handle 11 is linked to the power generation unit 12 based on the transmission unit 16, so that the power generation unit 12 generates electricity and is linked to output electrical energy for the smart door lock 10 to work.

[0163] It can be understood that the transmission unit 16 is a linkage device between the lock handle 11 and the power generation unit 12, and the transmission unit 16 can be implemented as a variety of devices, such as but not limited to gears, transmission shafts, belts and other mechanical devices. In some embodiments of the present invention, the transmission unit 16 is also allowed to be implemented as a spring, so that when the lock handle 11 is driven, the spring can be driven to accumulate potential energy, so as to drive the power generation unit 12 based on the spring.

[0164] Specifically, in this embodiment of the present invention, the transmission unit 16 includes a lock handle gear 161 and a generator gear 162, wherein the lock handle gear 161 is coaxially coupled to the lock handle 11 with the pivot axis of the lock handle 11, and the generator gear 162 is coupled to the power generation unit 12, wherein the lock handle gear 161 is meshed with the generator gear 162 to form a state in which the power generation unit 12 is linked to the lock handle 11, wherein when the lock handle 11 is pivotally driven, the lock handle gear 161 follows the lock handle 11 and makes a circular motion with its rotation axis as the axis, thereby linking the generator gear 162 to make a circular motion, thereby driving the power generation unit 12.

[0165] Preferably, the lock handle 11 is configured to increase the speed of driving the power generation unit 12 to increase the power generation of the power generation unit 12, thereby ensuring the stability of power supply and the working stability of the smart door lock 10. Specifically, the radius of the lock handle gear 161 is greater than the radius of the generator gear 162, so that the lock handle 11 can increase the speed of driving the power generation unit 12 based on the transmission unit 16. Specifically, when the lock handle 11 is pivotally driven, the lock handle gear 161 makes a circular motion with its rotation axis as the axis, thereby linking the generator gear 162 to make a circular motion. Since the radius of the lock handle gear 161 is greater than the radius of the generator gear 162, the speed of the generator gear 162 generated by the linkage of the lock handle gear 161 is higher than the speed of the lock handle gear 161. In this way, the process of the lock handle 11 driving the power generation unit 12 at an increased speed is realized, thereby increasing the power generation of the power generation unit 12 and ensuring the working stability of the smart door lock 10.

[0166] In particular, in some embodiments of the present invention, the lock handle 11 can be implemented to be driven by linear pulling. It can be understood that the lock handle 11 serves as a port for the user to operate the smart door lock 10, that is, the force input port of the smart door lock 10, and it can be driven in various ways.

[0167] It is understandable that there are various methods for implementing the automatic return of the lock handle 11, for example, the lock handle 11 returns under the action of elastic force, the lock handle 11 returns under the action of a reset spring, and the lock handle 11 returns due to mutually repelling magnetic forces. The present invention is not limited to this.

[0168] It is worth mentioning that in this embodiment of the present invention, the lock handle 11 is driven in a pivoting manner. Preferably, the pivoting angle of the lock handle 11 is set to be greater than 30° and less than 90°. Specifically, the pivoting angle of a traditional door handle is generally set to be greater than 30°, so the user's unlocking operation habit is to pivot the door handle more than 30°, so that the smart door lock 10 conforms to the user's traditional usage habits, improves the convenience of use of the smart door lock 10, and preferably the smart door lock 10 is set at a pivoting angle of the lock handle 11 exceeding 30° Unlocking can be achieved when the lock handle 11 is pivoted at an angle of more than 30°, the power generation capacity of the power generation unit 12 can meet the operation of the smart door lock 10, and the potential energy accumulated by the stepping drive unit 13 is sufficient to link the lock core unit 15 to unlock. The control unit 14 completes the identification work when powered and can control the stepping drive unit 13 to release the potential energy to link the lock core unit 15 to unlock, so that the user can complete the unlocking process in one unlocking operation, providing a smart door lock that conforms to the user's operating habits and environmental protection design concepts.

[0169] That is to say, compared with the prior art solutions, the smart door lock 10 provided by the present invention can be unlocked when the lock handle 11 is pivoted more than 30° once, without the need for tedious operations of pivoting the door handle multiple times or rotating the door handle multiple times, nor is there a need to keep the pivoted door handle waiting for a period of time until it has sufficient power to unlock as in the prior art. In other words, the smart door lock 10 provided by the present invention can be unlocked in real time by just twisting it, that is, the smart door lock 10 can complete the corresponding unlocking action in real time when the user pivots the lock handle 11 more than 30°.

[0170] Furthermore, the smart door lock 10 can temporarily store the potential energy accumulated in the stepping drive unit 13, so as to release the potential energy when needed, thereby eliminating the need for the user to maintain the unlocking operation for a long time, i.e., the user does not need to hold the lock handle 11 until the smart door lock 10 is unlocked. The smart door lock 10 uses the stored potential energy to drive the lock core unit 15 to move and unlock after the control unit 14 completes the user's identity authentication. This conforms to the user's operating habits and reduces the physical effort required for the user to operate the smart door lock 10, thereby improving the user's operating convenience and improving the practicality of the smart door lock 10.

[0171] Specifically, the stepping drive unit 13 is able to maintain its accumulated potential energy, specifically in the state where the lock handle 11 is driven, wherein the stepping drive unit 13 is linked to accumulate potential energy, and in the state where the locking handle 11 cancels the linkage force on the stepping drive unit 13, that is, after the lock handle 11 returns to its original position, the stepping drive unit 13 will not lose its accumulated potential energy due to the cancellation of the linkage force of the lock handle 11, that is, in the state where the linkage force of the lock handle 11 is canceled, the stepping drive unit 13 still has potential energy, so that the user does not need to maintain the unlocking operation for a long time to ensure the linkage force on the stepping drive unit 13, thereby improving the operational convenience of the smart door lock 10.

[0172] In particular, the stepping drive unit 13 includes a stepping arm 131, a force storage member 132 and an energy storage module 133, wherein the force storage member 132 is coupled to the stepping arm 131, and the stepping arm 131 is linked to the lock handle 11, wherein when the lock handle 11 is driven, the stepping arm 131 is linked to pull the force storage member 132 so that the force storage member 132 accumulates potential energy in the opposite direction of the movement direction of the stepping arm 131, wherein the energy storage module 133 is used to lock the position state of the stepping arm 131 to maintain the position state of the stepping arm 131 to avoid the The stepper arm 131 returns to its position under the influence of the potential energy accumulated in the force storage member 132, so that the stepper drive unit 13 can maintain the accumulated potential energy. In this way, when the linkage force of the lock handle 11 on the stepper arm 131 is cancelled, the position state of the stepper arm 131 is maintained, so that the force storage member 132 is continuously pulled by the stepper arm 131 to accumulate potential energy, thereby forming the potential energy retention of the stepper drive unit 13, so that the user does not need to maintain the unlocking operation for a long time to ensure the linkage of the lock handle 11 to the stepper drive unit 13, thereby improving the operating convenience of the smart door lock 10.

[0173] It is worth mentioning that, based on the maintenance of the position state of the stepping arm 131 by the energy storage module 133, the stepping drive unit 13 can maintain its accumulated potential energy in a step-by-step manner, and when the control unit 14 verifies that the identity of the user is legitimate, the potential energy is released to link the lock core unit 15 to unlock, so that unlocking is achieved by releasing potential energy, which is different from the prior art method of using mechanical energy to generate electricity and then using electrical energy to drive unlocking, and is more energy-saving, thereby improving the utilization efficiency of mechanical energy. And based on the energy storage module 133 maintaining the position state of the stepping arm 131 and maintaining the potential energy accumulated by the force storage member 132, the user can operate the smart door lock 10 more easily.

[0174] In particular, the stepper arm 131 is designed in a long strip shape in this embodiment of the present invention, while in some embodiments of the present invention, such as when the smart door lock 10 is implemented as a spherical structure, subject to the spherical shape, the stepper arm 131 can also be set to a ring shape or a circular tube shape, etc., that is, the specific shape of the stepper arm 131 is not fixed, and can be adjusted according to specific shapes and needs, such as but not limited to triangle, ring, square, ellipse, C-shape, etc. In addition, it can be understood that the stepper arm 131 is also allowed to be composed of multiple parts, and the specific shape of the stepper arm 131 does not constitute a limitation to the present invention.

[0175] It is worth mentioning that the energy storage module 133 includes a position adjusting component 1331, a position control rod 1332 and an unlocking valve 1333, wherein the position adjusting component 1331 is coupled to the stepping arm 131, one end of the position control rod 1332 is abutted against the unlocking valve 1333 and is locked by the unlocking valve 1333, wherein the position adjusting component 1331 is abutted against the other end of the position control rod 1332, so that the stepping arm 131 is locked by the energy storage module 133 based on the locking of the position control rod 1332 by the unlocking valve 1333, thereby maintaining the position state of the stepping arm 131, and the force storage component 132 is continuously pulled by the stepping arm 131 to accumulate potential energy.

[0176] Furthermore, the lock core unit 15 is linked to the stepping arm 131, and the energy storage module 133 is controlled by the control unit 14 to release the stepping arm 131, wherein when the control unit 14 authenticates the legality of the identity of the user, the control unit 14 controls the energy storage module 133 to release the stepping arm 131, and the stepping arm 131 returns to its original position under the potential energy accumulated by the force storage member 132, so as to link the lock core unit 15 to unlock and complete the unlocking process of the smart door lock 10, wherein the stepping arm 131 is locked by the energy storage module 133 when the control unit 14 fails to complete the identity authentication of the user, thereby making the force storage member 132 return to its original position. 2 is continuously pulled so that the stepping drive unit 13 keeps the potential energy stored, so that when the control unit 14 identifies the legal status of the user, the energy storage module 133 is controlled to release the stepping arm 131, so that the potential energy stored in the force storage member 132 is released, and then the stepping arm 131 is linked to return to the lock core unit 15 to unlock, so that the user does not need to maintain the unlocking posture, that is, the user does not need to keep the state of pivoting the lock handle 11 when the control unit 14 has not completed the identification work, so that the user can quickly pivot the lock handle 11 to complete the corresponding unlocking work, which meets the user's operating habits and improves the practicality of the smart door lock 10.

[0177] Specifically, the unlocking valve 1333 is communicatively connected to the control unit 14, wherein when the control unit 14 authenticates the legality of the identity of the user, the unlocking valve 1333 releases the position control rod 1332, thereby unlocking the position control rod 1332, wherein the position adjusting member 1331 disengages from the position control rod 1332 to form a state in which the stepping arm 131 is released by the energy storage module 133.

[0178] Furthermore, the positioning member 1331 is a plurality of locking positions arranged on the stepping arm 131, wherein the specific form of the locking position can be implemented as a tooth shape, a gear shape, a hole shape, a cylindrical shape, a grid shape, etc., and the present invention is not limited to this. The other end of the position control rod 1332 is provided with a lock 1334 that can be retracted and extended with the position control rod 1332, wherein the lock 1334 can be driven unidirectionally by the locking position, specifically, when the stepping arm 131 is linked to the locking handle 11, the locking position follows the movement of the stepping arm 131 to hit the lock 1334, and the lock 1334 retracts under the impact of the locking position to allow the stepping arm 131 to further pull the force storage member 132, that is, due to the retraction of the lock 1334, the locking position can smoothly pass through the lock 13 34 is in the position, so that the movement of the stepping arm 131 is not affected by the lock 1334. Further, the lock 1334 is reset after the blocking point passes to stop and abut the blocking point. Then, when the locking handle 11 cancels the linkage force on the stepping arm 131, the stepping arm 131 has a tendency to move in the opposite direction when it is linked with the locking handle 11 due to the potential energy accumulated by the force storage member 132, so that the blocking point abuts against the lock 1334. At this time, the lock 1334 is not affected by the movement of the blocking point and retracts to form a blocking of the blocking point, thereby preventing the stepping arm 131 from returning to its original position. In this way, the position state of the stepping arm 131 is locked, and the stepping arm 131 is prevented from returning to its original position under the influence of the potential energy accumulated by the force storage member 132 and releasing the potential energy prematurely.

[0179] It is worth mentioning that the lock 1334 is implemented as a device that can be retracted by being driven unidirectionally, for example but not limited to being implemented as an elastic buckle, movable pin, movable rod, etc., or being implemented as a movable buckle, hook, etc., and the present invention is not limited to this.

[0180] Specifically in this embodiment of the present invention, the lock 1334 includes an elastic member 13342 and a telescopic terminal 13341, wherein the elastic member 13342 is accommodated in the position control rod 1332, and the telescopic terminal 13341 is abutted against the elastic member 13342 to be telescopic at the other end of the position control rod 1332 under the elastic force of the elastic member 13342, wherein the morphological design of the telescopic terminal 13341 satisfies that it can be driven unidirectionally by the card point, specifically one side of the telescopic terminal 13341 is inclined or arc-shaped, specifically one side of the telescopic terminal 13341 that is hit by the card point when the stepping arm 131 is linked to the locking handle 11 is inclined or arc-shaped, so that when the stepping arm 131 is linked to the locking handle 11, the card point hits the inclined surface or arc surface of the telescopic terminal 13341 and can hit the inclined surface or arc surface of the telescopic terminal 13341. The locking mechanism 13341 of the embodiment of the present invention is actuated by the force storage member 1322, and the locking mechanism 13342 is actuated by the force storage member 1322, and the locking mechanism 13342 is actuated by the force storage member 1322.

[0181] It is worth mentioning that in this embodiment of the present invention, when the stepping arm 131 is linked to the locking handle 11, the card position moves upward and impacts to cause the lock 1334 to retract, and then the lock 1334 is locked in position when the lock 134 is reset, so that the potential energy accumulated by the force storage member 132 is maintained. In some embodiments of the present invention, there are other implementations of the locking method of the lock 1334 and the card position, such as the lock 1334 and the card position can be locked with each other, etc. The fixer 1334 swings to avoid when the locking point moves upward, and fixes the locking point when the stepping arm 131 has a tendency to move in the opposite direction when it is linked to the locking handle 11 due to the potential energy accumulated by the force storage member 132, thereby also maintaining the potential energy. The lock 1334 can also be integrally formed with the position control rod 1332. That is to say, as long as the lock 1334 can lock the position state of the stepping arm 131, its specific implementation methods are diverse and fall within the scope of the disclosure of the present invention.

[0182] In particular, those skilled in the art should understand that the morphology of the card site can have a variety of structural designs, such as but not limited to the card site being designed as a cylinder, a tooth, etc., wherein the specific morphology of the card site does not constitute a limitation to the present invention.

[0183] In addition, those skilled in the art can understand that the elastic member 13342 can be implemented as a single torsion spring, a double torsion spring, a circular spring or a spring sheet, and the telescopic terminal 13341 can be implemented as a pivot type, a swing type, etc., as long as the position of the stepping arm 131 can be locked in one direction, and the present invention is not limited to this.

[0184] It is understandable that the force storage member 132 can be implemented as an elastic element such as a single torsion spring, a double torsion spring, a round spring, a spring, a clockwork spring or a magnetic spring, and the specific form of the force storage member 132 does not constitute a limitation to the present invention.

[0185] Furthermore, the position control rod 1332 has a rotating shaft 13321 and is pivotally arranged on the rotating shaft 13321, wherein when the stepping arm 131 is locked by the energy storage module 133, the locking point is abutted against the lock 1334 and is locked, and the position control rod 1332 abuts against the unlocking valve 1333 and is locked, and then when the unlocking valve 1333 releases the position control rod 1332, the position control rod 1332 pivots to disengage the locking point from the lock 1334, thereby forming a state in which the stepping arm 131 is released by the energy storage module 133.

[0186] It is worth mentioning that in this embodiment of the present invention, the position control rod 1332 releases the stepping arm 131 in a pivoting manner, wherein the stepping arm 131 moves vertically up and down in this embodiment, and according to the disclosure of the present invention, in some embodiments of the present invention, the stepping arm 131 can also be designed to swing or rotate at a certain angle to disengage from the lock 1334, wherein the lock 1334 and the position control rod 1332 can also be implemented as an integrally molded structure, that is, the separation method between the position control rod 1332 and the stepping arm 131 can be set according to the specific implementation structure, and the present invention is not limited to this.

[0187] It can be understood that the unlocking valve 1333 can be implemented as a micro-motion solenoid valve, a low-power motor, a magnetostrictive element, a piezoelectric element or an electric device with a screw driving mechanism, so as to lock the position control rod 1332 under normal conditions and release the position control rod 1332 when the control unit 14 authenticates the user's identity as legitimate.

[0188] Specifically in this embodiment of the present invention, the unlocking valve 1333 is implemented as a micro-motion solenoid valve, wherein the unlocking valve 1333 releases the position control rod 1332 in a manner of retracting or advancing displacement, specifically, the unlocking valve 1333 has a lock buckle 13331, wherein one end of the position control rod 1332 is abutted against the lock buckle 13331 of the unlocking valve 1333 to form a state in which the position control rod 1332 is locked by the unlocking valve 1333, wherein the lock buckle 13331 is arranged in a state in which the control unit 14 authenticates the user's identity as legitimate and the unlocking valve 1333 retracts or advances to release the lock on the position control rod 1332, thereby allowing the position control rod 1332 to disengage from the lock buckle 13331 to form a state in which the stepping arm 131 is released by the energy storage module 133.

[0189] It can be understood that the specific structural form of the lock 13331 can be diverse. For example, the lock 13331 is configured to be a pivotable "L" shape, etc. That is to say, the mechanical control structure of the unlocking valve 1333 on the position control rod 1332 belongs to the lock 13331, that is, it belongs to the scope of disclosure of the present invention.

[0190] It is worth mentioning that the rotating shaft 13321 of the position control rod 1332 is arranged to be biased toward the end where the lock 1334 is located, so as to reduce the pulling force on the unlocking valve 1333 based on the lever principle, that is, when the stepping arm 131 is locked by the energy storage module 133, the potential energy pulling force accumulated by the force storage member 132 on the stepping arm 131 acts on the lock 1334 through the locking point, wherein the rotating shaft 13321 is arranged to be biased toward one end of the lock 1334, so that the pulling force on the unlocking valve 1333 is smaller than the pulling force on the lock 1334, that is, the pulling force on the lock buckle 13331 of the unlocking valve 1333 is smaller than the potential energy pulling force accumulated by the force storage member 132, thereby reducing the force required to drive the lock buckle 13331 of the unlocking valve 1333 to retract, correspondingly reducing the power consumption, and ensuring the working stability of the smart door lock 10.

[0191] In particular, the lock buckle 13331 is configured to retract or advance in a micro-distance manner, thereby reducing the movement stroke of the lock buckle 13331, thereby further reducing the power consumption of the unlocking valve 1333, so as to achieve low-energy unlocking work, ensure that the power generation of the power generation unit 12 meets the use requirements of the smart door lock 10, and thus ensure the working stability of the smart door lock 10.

[0192] Preferably, in this embodiment of the present invention, the rotating shaft 13321 is located at one end where the lock 1334 is located, so as to reduce the pulling force on the unlocking valve 1333 based on the lever principle. For example, assuming that the lock 1334 is subjected to a pulling force of 5N from the force storage member 132, by setting the rotating shaft 13321 of the position control rod 1332, the unlocking valve 1333 can be subjected to only a pulling force of 1N or less, thereby reducing the force required to drive the lock buckle 13331 of the unlocking valve 1333 to retract, and at the same time reducing the mechanical friction between the position control rod 1332 and the lock buckle 13331, thereby improving the structural reliability of the smart door lock 10 and ensuring the service life of the smart door lock 10.

[0193] Preferably, the contact area between the lock buckle 13331 of the unlocking valve 1333 and the position control rod 1332 is set to be less than 10 square millimeters, so as to further reduce the mechanical friction between the position control rod 1332 and the lock buckle 13331, improve the structural reliability of the smart door lock 10, and at the same time help reduce the power consumption of the unlocking valve 1333.

[0194] It is worth mentioning that during the operation of the smart door lock 10, the power consumption of the unlocking valve 1333 and the power consumption of the control unit 14 are mutually restrained. When the lock handle 11 is driven once, the electric energy generated by the power generation unit 12 is pulsed. Taking the user's door opening habit as an example, the lock handle 11 is driven once for about 0.8 seconds, and the electric energy generated by the power generation unit 12 is not abundant. In one drive of the lock handle 11, the voltage generated by the power generation unit 12 is about 4V, the current is about 30mA, and the duration is about 0.8s. Therefore, the total energy generated under ideal conditions is about 4*0.03*0.8=0.096 joules. When the total energy is constant, reducing the electric energy consumed by the unlocking valve 1333 is crucial to the working stability of the smart door lock 10, and is conducive to expanding the way in which the control unit 14 identifies the user's identity.

[0195] In particular, the lock buckle 13331 is configured to retract or advance in a micro manner so as to further reduce the power consumption of the unlocking valve 1333 by reducing the stroke of the lock buckle 13331. For example, in the process of driving the lock buckle 13331 to retract, a voltage of about 3.3V is used and a current of 100mA is discharged for 100ms so that the lock buckle 13331 can move 1mm under a pulling force of 2N, so that the position control rod 1332 is disengaged from the lock buckle 13331. That is to say, the energy consumed by the unlocking valve 1333 to work once is 3.3*0.1*0.1=0.033 joules, thereby realizing the micro-energy consumption operation of the unlocking valve 1333.

[0196] Therefore, the smart door lock 10 can achieve the beneficial effects of micro-power unlocking and macro-distance unlocking. It can be understood that the stroke of the lock buckle 13331 determines the power consumption of the unlocking valve 1333. Under the premise of a suitable lever ratio, the stroke of the lock buckle 13331 is set between 0.2mm-5mm and can be adjusted according to the lever ratio.

[0197] In other words, the power consumption of the unlocking valve 1333 is crucial to the reliable operation of the smart door lock 10. The power consumption of the unlocking valve 1333 needs to be controlled at a micro-power level, that is, the power consumption of the unlocking valve 1333 cannot be too large, otherwise the electric energy generated by the power generation unit 12 will be insufficient to support the smart door lock 10 to complete the unlocking process. As mentioned above, the electric energy generated by the power generation unit 12 when the lock handle 11 is pivoted 30° to 50° is limited. Although there is a technical solution in the prior art for placing a speed-increasing gear to improve the linkage effect, in actual application, setting too many speed-increasing gears or setting too large a speed-increasing ratio will cause the user to expend more physical strength to pivot the lock handle 11, resulting in a decrease in the practicality of the product. Therefore, in order to take into account the user's operating experience, According to experience, the electrical energy generated by the user pivoting the lock handle 11 to link the power generation unit 12 is only about 0.1 joule, and 0.1 joule of electrical energy needs to be allocated to the unlocking valve 1333 and the control unit 14. Therefore, the power consumption of the unlocking valve 1333 needs to be limited, and reducing the stroke of the lock buckle 13331 of the unlocking valve 1333 and / or shortening the working time both have a beneficial effect on the power consumption control of the unlocking valve 1333. It can be understood that the shorter the stroke of the lock buckle 13331 of the unlocking valve 1333, the more energy consumption can be saved, and the shorter the working time of the unlocking valve 1333, the more energy consumption can be saved. The working time of the unlocking valve 1333 and the stroke setting of the lock buckle 13331 are optimization solutions that take into account both working reliability and user operating experience.

[0198] Preferably, the stroke of the lock buckle 13331 of the unlocking valve 1333 is set to be less than or equal to 2.5 mm, and the working time of the unlocking valve 1333 is set to be less than or equal to 100 ms, so as to produce a power saving effect and realize the micro-energy consumption operation of the unlocking valve 1333.

[0199] In particular, the specific implementation methods of the unlocking valve 1333 are diverse. For example, in this embodiment of the present invention, the unlocking valve 1333 is composed of an electromagnet. In some embodiments of the present invention, the unlocking valve 1333 can also be implemented by an electric drive mechanism, for example, a screw is driven by a micro motor, and the lock 13331 is driven after the torque is increased by the screw, so as to further enhance the driving ability of the unlocking valve 1333 based on the conductive driving force of the screw.

[0200] To further elaborate, the energy storage module 133 can be understood as being configured as a "scale-shaped" structure, wherein one end of the position control rod 1332 is abutted against the unlocking valve 1333, and the locking point is abutted against the lock 1334 at the other end of the position control rod 1332 to transmit the potential energy accumulated by the force storage member 132 to the stepping arm 131, wherein the rotating shaft 13321 of the position control rod 1332 is biased toward the end where the lock 1334 is located, so that the energy storage module 133 can play a similar effect to a scale with the position control rod 1 The small force of the unlocking valve 1333 at one end of the position control rod 1332 controls the large force applied to the lock 1334 at the other end of the position control rod 1332, so that the unlocking valve 1333 can release the potential energy accumulated in the force storage member 132 with a small force, which has the beneficial effect of saving effort, thereby helping to reduce the power consumption of the unlocking valve 1333, so as to reduce the power demand of the unlocking valve 1333 for the power generation unit 12, so as to help reduce the force applied by the user to pivot the lock handle 11. It can be understood by those skilled in the art that the energy storage module The balance-shaped structure of block 133 should be understood as a mechanical labor-saving structure rather than a structure specifically referring to the appearance design. The shaft 13321 of the position control rod 1332 is biased toward the end where the lock 1334 is located, which can be understood as the distance between the lock 1334 and the shaft 13321 along the position control rod 1332 is smaller than the distance between the unlocking valve 1333 and the shaft 13321 along the position control rod 1332. For example, assuming that the distance between the lock 1334 and the shaft 13321 along the position control rod 1332 is 6 mm, the The distance between the unlocking valve 1333 and the rotating shaft 13321 along the position control rod 1332 is 30 mm, and the corresponding lever ratio is 5:1. Therefore, when the locking device 1334 is subjected to a pulling force of 5N from the force storage member 132, the force received by the unlocking valve 1333 is reduced to 1N. That is to say, the unlocking valve 1333 only needs to provide a force of 1N to release the position control rod 1332 to release the potential energy accumulated in the force storage member 132, without having to provide a force of 5N. This significantly reduces the power consumption of the unlocking valve 1333.Therefore, preferably, the ratio of the distance between the unlocking valve 1333 and the rotating shaft 13321 along the position control rod 1332 to the distance between the lock 1334 and the rotating shaft 13321 along the position control rod 1332 is preferably set to be greater than 1, so that the unlocking valve 1333 can control the force storage member 132 to release the potential energy with a force less than the potential energy pulling force accumulated by the force storage member 132, thereby significantly reducing the power consumption of the unlocking valve 1333 on the one hand to ensure the working stability of the smart door lock 10 and helping to reduce the driving force of the user to pivot the lock handle 11; on the other hand, since the unlocking valve 1333 can control the force storage member 132 to maintain the potential energy with a smaller force, it is helpful to reduce the mutual friction between the unlocking valve 1333 and the position control rod 1332, so as to help extend the service life of the smart door lock 10.

[0201] Therefore, different from the Chinese utility model patent with announcement number CN210622517U in which the locking release member directly acts on the force storage member, the power consumption of the unlocking valve 1333 in the present invention can be significantly reduced. Taking the data in the above example as an example, in the Chinese utility model patent with announcement number CN210622517U, the locking release member directly acts on the force storage member. Therefore, when the pulling force generated by the force storage member is 5N, the locking release member needs to provide a corresponding force of 5N to release the force storage member, and its power consumption increases accordingly. Therefore, the smart door lock 10 provided by the present invention has significant energy-saving advantages and has wide application value.

[0202] It is also worth mentioning that Figure 2DAs shown, the energy storage module 133 is further allowed to include a reverse thrust elastic member 1335', ​​wherein when the clamping position is locked by the telescopic terminal 13341, the potential energy pulling force accumulated by the force storage member 132 is applied to the telescopic terminal 13341, wherein based on the elastic force characteristics of the reverse thrust elastic member 1335', ​​the reverse thrust elastic member 1335' can generate a reaction force on the position control rod 1332 to further reduce the load on the unlocking valve 1333 Specifically, the reverse thrust elastic member 1335' abuts against the position control rod 1332 at the side of the rotating shaft 13321 that is biased toward the unlocking valve 1333, so that when the telescopic terminal 13341 is locked at the locking position, the pulling force of the force storage member 132 acts on the telescopic terminal 13341 and is transmitted to the position control rod 1332 and the reverse thrust elastic member 1335' through the telescopic terminal 13341, and the reverse thrust elastic member 1335' is stressed and The position control rod 1332 generates a reaction force on the side of the rotating shaft 13321 that is biased toward the unlocking valve 1333 to overcome the tension applied to the position control rod 1332 by the force storage member 132 on the side of the rotating shaft 13321 that is biased toward the locking device 1334, thereby reducing the force applied to the unlocking valve 1333. For example, assuming that the telescopic terminal 13341 is subjected to a 5N tension from the force storage member 132, the reverse push elastic member 1335' Under force, the position control rod 1332 generates a force of 4.5N on the side of the rotating shaft 13321 that is biased towards the unlocking valve 1333, so that the force difference between the two sides of the rotating shaft 13321 of the position control rod 1332 is reduced to 0.5N. When the lever ratio is 5:1, the force applied to the unlocking valve 1333 is only 0.1N. Therefore, the power consumption of the unlocking valve 1333 can be further reduced, which has a significant energy consumption advantage compared to the prior art.And when the control unit 14 has authenticated the user's identity as legal, the lock buckle 13331 is subjected to a force of only 0.1N and can be retracted or advanced under the supply of tiny electric energy, thereby releasing the position control rod 1332. At this time, the reverse thrust elastic member 1335' generates a reaction force on the position control rod 1332 on the side of the rotating shaft 13321 that is biased toward the unlocking valve 1333, which is smaller than the pulling force applied to the position control rod 1332 by the force storage member 132 on the side of the rotating shaft 13321 that is biased toward the lock 1334, so that the position control rod 1332 pivots on the rotating shaft 13321 to disengage the locking point from the telescopic terminal 13341. At this time Based on the elastic potential energy of the reverse thrust spring member 1335', ​​the position control rod 1332 is pivoted in the opposite direction and reset under the action of the reverse thrust spring member 1335'. ​​That is to say, the reverse thrust spring member 1335' can generate a reaction force on the side of the position control rod 1332 on the rotating shaft 13321 that is biased toward the unlocking valve 1333, so as to apply the force storage member 132 to the telescopic terminal 13341, so as to further save the power consumption of the unlocking valve 1333. At the same time, based on the setting of the reverse thrust spring member 1335', ​​the position control rod 1332 can be pivoted in the opposite direction and reset under the action of the reverse thrust spring member 1335', ​​and can be locked by the unlocking valve 1333 after being reset.

[0203] In particular, in this embodiment of the present invention, the reverse thrust spring piece 1335' is arranged on the rotating shaft 13321 of the position control rod 1332. It can be understood that in some embodiments of the present invention, the smart door lock 10 can also be provided with other elastic elements on the side of the position control rod 1332 that is biased towards the unlocking valve 1333 of the rotating shaft 13321 to generate a reaction force, and its effect is equivalent to the reverse thrust spring piece 1335', ​​and its specific position layout does not constitute a limitation to the present invention.

[0204] That is to say, when the potential energy accumulated in the force storage member 132 acts on the position control rod 1332, the end of the position control rod 1332 locked by the unlocking valve 1333 will generate lifting potential energy accordingly. The greater the potential energy accumulated in the force storage member 132, the greater the pulling force on the unlocking valve 1333, and the greater the electric energy required for unlocking. At this time, the reaction force generated by the reverse thrust elastic member 1335' is applied to the position control rod 1332 to reduce the lifting potential energy of the position control rod 1332, thereby reducing the force on the unlocking valve 1333, thereby saving the power consumption of the unlocking valve 1333.

[0205] It can be understood that the specific shape of the position control rod 1332 does not constitute a limitation to the present invention. For example, in some embodiments, the position control rod 1332 can also be designed to be L-shaped, O-shaped, triangular, polygonal, elliptical, gear-shaped, or a combination of multiple geometric shapes, as long as the technical effect of the unlocking valve 1333 based on the position control rod 1332 can be controlled by the force of the potential energy pulling force accumulated by the force storage member 132 to release the potential energy, and in some embodiments, in order to further reduce the force applied to the unlocking valve 1333, it is also allowed to further add a lever structure between the unlocking valve 1333 and the position control rod 1332 to further optimize the power consumption of the unlocking valve 1333. Those skilled in the art should understand that the device composed of multiple lever structures is equivalent to the position control rod 1332.

[0206] It is worth mentioning that the unlocking valve 1333 can work with micro-energy consumption so that more energy is allocated to the control unit 14, thereby ensuring the working stability of the control unit 14 and supporting the control unit 14 to expand the way of identifying the user's identity, such as but not limited to, the control unit 14 identifies the user's identity by Bluetooth pairing with the user's mobile phone, the control unit 14 identifies the user's identity by NFC pairing, the WiFi pairing method, the radio frequency signal pairing method, etc., and because the control unit 14 can be allocated more energy, the energy allocated by the control unit 14 can also support the control unit 14 to identify the user's identity by biometric identification, such as fingerprint identification, facial recognition. The identity of the user, etc. In addition, it is worth mentioning that the control unit 14 also allows the identity of the user to be identified by receiving control instructions through the network, so that the user can remotely control the smart door lock 10 through the network. For example, when there is a visitor, the user can issue an unlocking instruction to the gateway. After receiving the remote unlocking instruction, the gateway temporarily stores the instruction and waits for the request data of the control unit 14. Within the set window time, such as 1 minute, when the visitor drives the lock handle 11, the control unit 14 is powered to request verification information from the gateway. When the corresponding verification procedure verifies that it is correct, the identity of the user is identified, so that the visitor can also unlock the door through traditional unlocking operations, thereby improving the convenience of use of the smart door lock 10 and improving the practicality and intelligence level of the smart door lock 10.

[0207] Specifically, in the prior art, although the remote unlocking operation can be realized for the smart lock, it is realized based on battery power supply, wherein the smart lock can be in a standby state based on the battery power supply, and when the user remotely issues an unlocking command to the smart lock, the smart lock can be unlocked under the premise of battery power supply, and different from the prior art, the smart door lock 10 provided by the present invention has no power supply when it is not operated, at this time, even if the user remotely sends an unlocking command, the smart door lock 10 cannot achieve the corresponding unlocking using the prior art, so the present invention also provides an unlocking control method of the smart door lock 10, wherein the unlocking control method of the smart door lock 10 comprises the steps of:

[0208] (a) sending an unlocking command to a gateway from a terminal device;

[0209] (b) driving a lock handle 11 to drive a power generation unit 12 to generate electrical energy and to drive a stepping drive unit 13 to accumulate and maintain potential energy;

[0210] (c) based on the power supply of the power generation unit 12, a control unit 14 interacts with the gateway to receive the unlocking instruction;

[0211] (d) Based on the control unit 14 receiving the unlocking instruction, the stepping drive unit 13 releases potential energy to link a lock core unit to unlock.

[0212] Preferably, before step (c), a step of setting a window time is also included, wherein the control unit 14 needs to exchange information with the gateway within the window time. Specifically, the setting of the window time ensures the safety of the use of the smart door lock 10. It can be understood that the control unit 14 needs to exchange information with the gateway within the window time. When the control unit 14 exchanges information with the gateway within the window time, the unlocking instruction can be received smoothly. When the window time is exceeded, the control unit 14 cannot receive the unlocking instruction smoothly, thereby ensuring that the smart door lock 10 will not be illegally opened by others.

[0213] Furthermore, in step (a), the gateway is configured to temporarily store the unlock instruction, so that after the control unit 14 is powered by the electric energy generated by the lock handle 11 and the power generation unit 12, the unlock instruction is sent to the control unit 14. Specifically, in step (c), the control unit 14 sends a request message to the gateway after being supplied with electric energy, and the gateway is configured to send the unlock instruction to the control unit 14 after receiving the request message. It can be understood that the gateway only exchanges information after the control unit 14 is supplied with electric energy, which is conducive to reducing the channel occupancy time and ensuring the reliability of communication. Based on the step that the control unit 14 sends the request message to the gateway and the gateway sends the unlock instruction after receiving the request message, the gateway can obtain when the smart door lock 10 is unlocked.

[0214] It is worth mentioning that the window time can be understood as the period from the time when the user sends the unlocking command to the gateway through the terminal device to the time when the visitor drives the lock handle and the control unit 14 is powered to interact with the gateway for information. It can be understood that the specific duration of the window time can be set according to usage needs. Preferably, the window time is set to 10s-120s to ensure the safety of the smart door lock 10.

[0215] It can be understood that the terminal device is a device that can be communicatively connected to the gateway, such as but not limited to a mobile phone, a computer, a mobile communicator, etc.

[0216] It is worth mentioning that in some embodiments of the present invention, the gateway can also be configured to continuously send the unlock instruction after receiving the unlock instruction, so as to receive the unlock instruction after the control unit 14 is supplied with power. Specifically, in the step (a), the gateway is configured to continuously send the unlock instruction, so as to receive the unlock instruction after the control unit 14 is supplied with power.

[0217] Furthermore, the control unit 14 can identify the user's identity by pairing with the user's terminal device, such as Bluetooth, NFC, WiFi, radio frequency signals, etc., so that the user can unlock the door through traditional unlocking operations. Specifically, the present invention also provides an unlocking control method of a smart door lock 10, which is used to realize the identification of the user's identity by the smart door lock 10 based on the pairing and binding of the user's terminal device with the control unit 14, wherein the unlocking control method of the smart door lock 10 includes the steps of:

[0218] (i) Binding the smart door lock 10 to at least one terminal device;

[0219] (ii) driving a lock handle 11 to drive a power generation unit 12 to generate electrical energy and a stepping drive unit 13 to accumulate and maintain potential energy;

[0220] (iii) based on the power supply of the power generation unit 12, a control unit 14 sends a synchronization signal to the terminal device, and the terminal device sends an unlocking instruction on the premise that the synchronization signal is legal;

[0221] (iv) Based on the control unit 14 receiving the unlocking instruction, the stepping drive unit 13 releases potential energy to link a lock core unit 15 to unlock.

[0222] It is worth mentioning that the terminal device needs to send the unlocking instruction after the control unit 14 sends the synchronization signal to it and the synchronization signal is legal, so that the terminal device can know the working status of the smart door lock 10, and avoid the terminal device from continuously sending the unlocking instruction to interfere with the channel and affect the safe use of the smart door lock 10, and it is beneficial to reduce the power consumption of the terminal device. The terminal device will only determine that the synchronization signal is in a legal state after being bound to the smart door lock 10, so as to ensure the safe use of the smart door lock 10.

[0223] Preferably, the unlocking control method of the smart door lock is configured to complete step (iii) and step (iv) within a time of less than or equal to 0.9 seconds, so that when the user drives the lock handle 11, the smart door lock 10 can complete the corresponding unlocking work in time to enhance the user's experience.

[0224] In particular, the unlocking valve 1333 can work with low energy consumption, reducing the demand for electric energy, thereby helping to reduce the driving force of the lock handle 11 on the power generation unit 12, which is correspondingly helpful to reduce the physical strength required by the user to drive the lock handle 11, so as to further improve the convenience of use of the smart door lock 10 and give the user a good user experience. Preferably, in order to further reduce the driving power consumption of the unlocking valve 1333, by optimizing the magnetic circuit design, the unlocking valve 1333 requires a driving current of 100mA at a driving voltage of 3V, the driving time is less than 10mS, and the energy consumed is 3000uJ, which further saves 90% of the electric energy. Therefore, the present invention achieves an extremely energy-saving state, and enables the present invention to realize intelligent unlocking under the action of very light torsional force. The unlocking feeling is as light as that of a traditional mechanical lock, and there is no sense of weight due to the presence of the power generation unit 12. Of course, this preferred method is based on the complete technical solution of the present invention, so there is no need to comment on the role of a single component in isolation.

[0225] Furthermore, in this embodiment of the present invention, the stepping arm 131 is linked by the lock handle 11 to move in a direction perpendicular to the horizontal plane, and the force storage member 132 is coupled to one end of the stepping arm 131, so that when the stepping arm 131 is linked by the lock handle 11 to move in a direction perpendicular to the horizontal plane, the force storage member 132 can accumulate potential energy sufficient to drive the lock core unit 15 to unlock, thereby ensuring the working stability of the smart door lock 10.

[0226] In particular, the card position is arranged on the stepping arm 131 so as to be biased toward the other end of the stepping arm 131, so as to enhance the strength of the stepping arm 131 returning to its original position under the action of the potential energy accumulated in the force storage member 132, thereby ensuring the effectiveness of the stepping arm 131 in linking the lock core unit 15 to unlock, and correspondingly ensuring the working stability of the smart door lock 10.

[0227] It is worth mentioning that the smart door lock 10 includes a driving unit 17, wherein the driving unit 17 includes a linkage arm 171 and a driving arm 172, wherein the linkage arm 171 is connected to the lock handle 11, so as to pivot along with the lock handle 11 when the lock handle 11 is pivotally driven, wherein the driving arm 172 is arranged on the periphery of the linkage arm 171, so that when the lock handle 11 is pivotally driven, the driving arm 172 abuts against the stepping arm 131 to link the stepping arm 131, specifically, when the lock handle 11 is pivotally driven, the linkage arm 171 pivots along with the lock handle 11, so that the driving arm 172 is lifted by the linkage arm 171, thereby abutting against the stepping arm 131 to link the stepping arm 131 to be lifted in a direction perpendicular to the horizontal plane.

[0228] It is worth mentioning that the stepping arm 131 is provided with a driving groove 1311, wherein when the locking handle 11 is pivotally driven, the linkage arm 171 pivots along with the locking handle 11 to lift the driving arm 172, so that the driving arm 172 abuts against the groove wall of the driving groove 1311 to link the stepping arm 131 to be linked by the locking handle 11, thereby forming a state in which the stepping driving unit 13 is linked and coupled to the locking handle 11.

[0229] In particular, based on the setting of the drive slot 1311, when the lock handle 11 is released at any time during the pivoting process, the lock handle 11 can remain restored to its original state, thereby ensuring the aesthetics of the smart door lock 10. When the power generated by the power generation unit 12 is insufficient, the user can pivot the lock handle 11 again to link the power generation unit 12 to generate electricity again.

[0230] In detail, refer to the accompanying drawings of the present invention. FIG. 2A to FIG. 2D, wherein the smart door lock 10 is in a state of waiting for energy storage (such as Figure 2A As shown), at this time, the force storage member 132 is not pulled by the stepping arm 131, and the locking point is located below the lock 1334, so that the smart door lock 10 is in the state of accumulating potential energy (as shown in FIG. Figure 2B As shown), that is, the state in which the lock handle 11 is driven by the user, the lock handle 11 links the stepping arm 131 to be lifted in a direction perpendicular to the horizontal plane, so that the card position follows the stepping arm 131 to be lifted, thereby hitting the telescopic terminal 13341 of the lock 1334, and applying force to the elastic member 13342 to compress the elastic member 13342, thereby causing the telescopic terminal 13341 to retract at the position control rod 1332, and the card position smoothly passes through the position of the lock 1334 so that the stepping arm 131 can be further lifted, and further when the smart door lock 10 is in a state of maintaining potential energy (as shown Figure 2CAs shown), after one of the card positions passes through the lock 1334, the elastic member 13342 is reset to push the telescopic terminal 13341 to extend out of the position control rod 1332 to stop the card position passing through the lock 1334 from moving downward, that is, to prevent the stepping arm 131 from moving downward to avoid the potential energy accumulated by the force storage member 132 from being released, thereby forming the potential energy retention of the smart door lock 10, wherein under the impact of the next card position, the telescopic terminal 13341 retracts at the position control rod 1332, and resets and extends out after the card position passes, thereby forming The potential energy of the smart door lock 10 is maintained step by step, so as to improve the convenience of use for the user. For example, the pivot angle of the lock handle 11 is greater than 30°, and the user stops further pivoting the lock handle 11 after pivoting 10°. At this time, the locking point is locked by the lock 1334, preventing the stepping arm 131 from moving downward to release the potential energy accumulated in the force storage member 132, and preventing the stepping arm 131 from reacting on the lock handle 11 to cause the lock handle 11 to return quickly and injure the user, thereby ensuring the safety of use of the smart door lock 10, and when the user pivots again When the lock handle 11 is rotated, the force during the initial pivoting becomes lighter because the stepping arm 131 is locked by the energy storage module 133. When the user pivots the lock handle 11, there is no need to link the stepping arm 131 to pull the force storage member 132 again, thereby reducing the corresponding pivoting force, especially when the user cannot successfully complete the unlocking operation in one unlocking operation, such as when the user pivots the lock handle 11 too slowly, resulting in the power generation of the power generation unit 12 being insufficient to supply the smooth operation of the smart door lock 10 and the inability to successfully complete the unlocking. When the user pivots the lock handle 11 again to unlock the door, the power generation unit 12 is insufficient to supply the smart door lock 10. , the force for pivoting the lock handle 11 becomes lighter, because the stepping arm 131 is locked by the energy storage module 133, and the user does not need to link the stepping arm 131 again to pull the force storage member 132 when pivoting the lock handle 11. Therefore, when the user performs another unlocking operation, it is only necessary to link the power generation unit 12 to generate electricity, which is convenient for the user's operation, provides the user with a convenient operation experience, and improves the practicality of the smart door lock. Furthermore, when the control unit 14 identifies the user's identity as legal, the smart door lock 10 switches from the potential energy maintaining state to the potential energy releasing state (such as Figure 2DAs shown), the lock buckle 13331 of the unlocking valve 1333 is slightly retracted to disengage the position control rod 1332 from the lock buckle 13331, and under the action of the force at the locking position being locked by the lock 1334, the position control rod 1332 pivots on its rotating shaft 13321, thereby disengaging the locking position from the locking of the lock 1334, so that the stepping arm 131 moves downward under the pull of the force storage member 132, and links the lock core unit 15 to unlock, completing the unlocking process of the smart door lock 10.

[0231] In particular, in order to further understand the process of maintaining the potential energy of the smart door lock 10 of the present invention, the present invention also provides a method for maintaining the potential energy of the smart door lock 10, wherein the method for maintaining the potential energy of the smart door lock 10 comprises the steps of:

[0232] (A) The stepping arm 131 moves due to an external force;

[0233] (B) Based on the movement of the stepping arm 131 , a force storage member 132 is linked to store potential energy in a direction opposite to the movement direction of the stepping arm 131 ;

[0234] (C) Locking the stepping arm 131 to maintain the position of the stepping arm 131 and prevent the stepping arm 131 from returning to its original position under the influence of the potential energy accumulated in the force storage member 132 , thereby maintaining the potential energy.

[0235] In one embodiment, the step (C) further comprises the steps of:

[0236] (C1) An unlocking valve 1333 locks a control rod 1332;

[0237] (C2) a locking point disposed at the stepping arm 131 hits the position control rod 1332 so that a lock 1334 of the position control rod 1332 retracts into the position control rod 1332;

[0238] (C3) The locker 1334 is reset after passing the locking point to lock and abut against the locking point, thereby preventing the stepping arm 131 from returning to its original position under the influence of the potential energy accumulated in the force storage member 132 .

[0239] In one embodiment, the step (C1) further comprises the steps of:

[0240] (C1.1) A lock buckle of the unlocking valve 1333 extends out of the unlocking valve 1333 at 13331;

[0241] (C1.2) The position control rod 1332 abuts against the lock buckle 13331 .

[0242] Furthermore, since the energy storage module 133 locks the stepping arm 131, the potential energy of the smart door lock 10 is maintained when the control unit 14 has not completed the identification work, so that the driving force when the user pivots the lock handle 11 again can be reduced, and the smart door lock 10 can be started through a corresponding interactive path, for example, by setting the number of times the lock handle 11 is driven to start the corresponding pairing program, such as driving the lock handle 11 three times in a row to start the pairing program of the control unit 14, wherein in the process of driving the lock handle 11 for the first time, the smart door lock 10 completes the accumulation and maintenance of potential energy, so that when the user drives the lock handle 11 again, the corresponding driving force is reduced, which is convenient for the user. Operation, wherein the lock handle 11 is linked to the power generation unit 12 to generate electrical energy to supply power to the control unit 14, driving the lock handle 11 three times increases the energy generated by the power generation unit 12, thereby ensuring the working stability of the smart door lock 10, wherein the power generation unit 12 supplies power to the control unit 14 and sends the generated three pulse data to the control unit 14, the control unit 14 is configured to determine that three consecutive power generation operations are network distribution operations, thereby issuing a network distribution request, and the user responds to the corresponding network distribution request through a device such as a mobile phone to form a pairing binding with the smart door lock 10, thereby completing the setting of the smart door lock 10 based on the corresponding interactive operation, thereby improving the convenience of using the smart door lock 10.

[0243] Further, the downward movement of the stepping arm 131 is linked to unlock the lock core unit 15, and the lock core unit 15 includes a lock core gear 151 and a lock core driving member 152, wherein the lock core gear 151 is linked to the stepping arm 131, so that when the stepping arm 131 is linked, the lock core gear 151 is linked to rotate, and the lock core driving member 152 is linked to unlock when the lock core gear 151 rotates in a set direction, so as to realize the unlocking procedure of the smart door lock 10, specifically, in When the stepping arm 131 moves downward and the lock core gear 151 is linked to rotate, the lock core driving member 152 is unlocked in conjunction with it. However, when the stepping arm 131 is lifted upward by the lock handle 11 and the lock core gear 151 is linked to rotate, the lock core driving member 152 will not be unlocked in conjunction with it. That is, the lock core driving member 152 is an element driven unidirectionally by the lock core gear 151. For example, the lock core driving member 152 and the lock core gear 151 are implemented as interacting ratchets, etc., and the present invention is not limited to this.

[0244] Specifically, the lock core drive 152 links the lock tongue to retract so as to unlock the smart door lock 10. The structural relationship between the lock core drive 152 and the lock tongue can be diverse, such as being designed as an integral whole, as long as the lock tongue can retract when the lock core drive 152 rotates.

[0245] In particular, the stepping arm 131 includes a driving tooth 1312, wherein the driving tooth 1312 is meshed with the lock core gear 151 to form a state in which the lock core gear 151 is linked to the stepping arm 131, wherein the stepping arm 131 is linked by the lock handle 11 so that the driving tooth 1312 drives the lock core gear 151 to rotate in one direction, and then in the state in which the stepping arm 131 is linked back by the potential energy accumulated by the force storage member 132, the driving tooth 1312 drives the lock core gear 151 to rotate in another direction, wherein the lock core driving member 152 is linked to be unlocked by the lock core gear 151 in the state in which the stepping arm 131 returns and links the lock core gear 151 to rotate, thereby realizing the unlocking procedure of the smart door lock 10.

[0246] Furthermore, in this embodiment of the present invention, the control unit 14 is configured to control the stepper drive unit 13 based on the identification result of the user after the lock handle 11 returns to the set position, that is, the smart door lock 10 is configured to be unlocked after the user completes the action of pivoting the lock handle 11, so as to avoid the state where the lock handle 11 has not returned to its position and the control unit 14 identifies the identity of the user as legitimate and controls the stepper drive unit 13 to release potential energy, resulting in the potential energy release of the stepper drive unit 13 reacting on the lock handle 11 and injuring the user, thereby ensuring the operational safety of the smart door lock 10.

[0247] Specifically, the smart door lock 10 includes a return sensor 18, wherein the return sensor 18 is communicatively connected to the control unit 14, and the return sensor 18 is used to detect the state of the lock handle 11. The control unit 14 is configured to control the stepping drive unit 13 based on its identification result of the user when the return sensor 18 detects that the lock handle 11 returns to a set position, and preferably performs corresponding unlocking work when the lock handle 11 returns to a normal state to avoid the return linkage of the lock handle 11 when the stepping drive unit 13 releases potential energy, thereby avoiding harm to the user, thereby ensuring the operational safety of the smart door lock 10.

[0248] It is worth mentioning that the return sensor 18 is a position sensor, which determines the state of the lock handle 11 by detecting the specific position of the lock handle 11, so that the smart door lock 10 starts the corresponding work when the lock handle 11 reaches the set position. Therefore, the specific component position of the return sensor 18 is not limited, and it is preferably located in the movement path of the lock handle 11. The function of the return sensor 18 can be realized by mechanical components, electronic components, and detection chips.

[0249] In detail, refer to the accompanying drawings of the present invention. FIG. 3A to FIG. 3B The user operates the smart door lock 10 by pivoting the lock handle 11 (specifically, Figure 3A As shown), the lock handle 11 is pivotally driven to link the lock handle gear 161 to make a circular motion and then link the generator gear 162 to make a circular motion, thereby driving the power generation unit 12 to generate electrical energy, wherein the pivoting of the lock handle 11 also links the linkage arm 171, so that the drive arm 172 is lifted and abuts against the groove wall of the drive tooth 1312, thereby linking the stepping arm 131 to lift in a direction perpendicular to the horizontal plane, so as to pull the force storage member 132 to accumulate potential energy, and drive the locking point to impact the telescopic terminal 13341, so as to apply force to compress the elastic member 13342 so that the telescopic terminal 13341 retracts at the position control rod 1332, and the locking point smoothly passes through the lock 1334 The position enables the stepping arm 131 to be further lifted, wherein after one of the card positions passes through the lock 1334, the elastic member 13342 is reset to push the telescopic terminal 13341 to extend out of the position control rod 1332 to stop the card position passing through the lock 1334 from moving downward, wherein under the impact of the next card position, the telescopic terminal 13341 retracts at the position control rod 1332, and resets and extends after the card position passes, thereby forming a step-by-step maintenance of the potential energy of the smart door lock 10, further when the return sensor 18 detects that the lock handle 11 has returned to its original position, and the control unit 14 identifies the user's identity as legal, for specific reference. Figure 3B, wherein the lock buckle 13331 of the unlocking valve 1333 is controlled by the control unit 14 to produce a micro-retraction, so that the position control rod 1332 is disengaged from the lock buckle 13331, and is stopped at the locking point under the force of the lock 1334, that is, under the pulling force of the force storage member 132, the position control rod 1332 pivots on its rotating shaft 13321, so that the locking point is disengaged from the locking of the lock 1334, so that the stepping arm 131 moves downward under the pulling of the force storage member 132, and the driving tooth 1312 of the stepping arm 131 drives the lock core gear 151 to rotate, so as to link the lock core driving member 152 to unlock, so as to realize the unlocking procedure of the smart door lock 10, so as to realize self-generation, identity authentication and complete the unlocking procedure during the user's unlocking operation, efficiently realize the unlocking process, give the user a safe and convenient use experience, and improve the practicality of the smart door lock 10.

[0250] To further understand the operation of the smart door lock 10, the present invention further discloses a step of applying an external force to the stepping arm 131, including:

[0251] (I) driving a lock handle 11;

[0252] (II) Transmitting external force to the stepping arm 131 based on the movement of the lock handle 11 .

[0253] Specifically in one embodiment, in the step (I), the locking handle 11 is driven in a pivoting manner.

[0254] It is worth mentioning that in this embodiment of the present invention, the smart door lock 10 is self-powered without the need for a battery. However, according to the technical solution disclosed by the present invention, in some applications, the technical solution of the present invention is also allowed to be applied to a battery-powered smart door lock, so as to utilize the electric energy generated by the power generation unit 12 to power the battery. Moreover, based on this embodiment of the smart door lock 10 disclosed in the present invention, the power consumption of the smart door lock 10 is low and the energy-saving effect is obvious. When the technical solution of the present invention is applied to a battery-powered smart door lock, the service life of the battery can be greatly extended. Based on the supplement of electric energy by the power generation unit 12, the battery replacement cycle is further extended. That is to say, when the technical solution of the present invention is applied to a battery-powered smart door lock, it can also bring beneficial effects.

[0255] In particular, in the existing battery-powered smart door lock, its high power consumption is mainly caused by the need to rely on electric energy to drive the lock core to unlock. Ninety percent of the battery's electric energy is consumed by the motor that drives the lock core. Taking the application of the existing smart door lock as an example, 8 batteries can only be used for about half a year. When the technical solution disclosed in the present invention is applied to the battery-powered smart door lock, the lock handle 11 is linked to the stepping drive unit 13 to accumulate and maintain potential energy, and then the lock core unit 15 is linked to perform the corresponding unlocking action, thereby avoiding the energy consumption caused by direct motor driving the lock core. In this way, the battery's electric energy only needs to be supplied to the control unit 14 and the unlocking valve 1333 to complete the corresponding work, and the unlocking valve 1333 has low power consumption. Two batteries can be used for the smart door lock for about one year, thereby significantly extending the battery life and reducing the battery usage, having good practicality and meeting the environmental protection concept.

[0256] For ease of understanding, a smart door lock unlocking control method is also provided, wherein the smart door lock unlocking control method comprises the steps of:

[0257] (1) An energy storage module 133 stores elastic potential energy;

[0258] (2) controlling the energy storage module 133 to release the elastic potential energy to a lock core unit 15;

[0259] (3) Based on the release of the elastic potential energy, the lock core unit 15 is driven to unlock.

[0260] Therefore, those skilled in the art can understand that the implementation of applying the technical solution of the present invention to a smart door lock with a battery falls within the protection scope of the present invention.

[0261] Furthermore, the present invention also provides an unlocking control method for a smart door lock, wherein the unlocking control method for the smart door lock comprises the steps of:

[0262] Step 1: An unlocking valve 1333 locks one end of a first control rod 1332 in a normal state;

[0263] Step 2: Based on the operation of a lock handle 11, a force storage member 132 generates elastic potential energy, and the elastic potential energy directly or indirectly acts on the other end of the position control rod 1332, so as to latch the elastic potential energy based on the state that the position control rod 1332 is locked by the unlocking valve 1333, so that the elastic potential energy can be temporarily maintained;

[0264] Step 3: Based on the authentication of the user's identity by a control unit 14, the unlocking valve 1333 is powered on to release the lock on the position control rod 1332, and the position control rod 1332 moves to release the elastic potential energy;

[0265] Step 4, the elastic potential energy is released to a lock core unit 15 to unlock the lock core unit 15;

[0266] Step 5: Based on the release of the elastic potential energy, the position control rod 1332 is reset and locked by the unlocking valve 1333 again.

[0267] It is worth mentioning that, in the present invention, in order to ensure that the elastic potential energy generated by the force storage member 132 can be maintained after the operator's hand leaves the lock handle 11; or, before any time when the control unit 14 needs to be unlocked, the elastic potential energy can be automatically maintained for a period of time; therefore, the present invention adopts a technical solution of "latching" elastic potential energy, that is, in the "latched" state, the elastic potential energy can be temporarily maintained and will not be released in advance, and the elastic potential energy will not be released to the lock core unit 15 until it is needed to be unlocked, so that the user does not need to maintain the unlocking operation.

[0268] In particular, the elastic potential energy is temporarily maintained, that is, after the elastic potential energy is generated, the elastic potential energy is maintained for a period of time until the control unit 14 identifies the user's identity as legal and the unlocking valve 1333 is powered on to release the lock on the position control rod 1332. Preferably, it is set between 0.1s-5s, and it can be understood that when the control unit 14 identifies the user's identity as illegal, the elastic potential energy will be continuously maintained.

[0269] In one embodiment, the pulling force applied to the unlocking valve 1333 is smaller than the elastic potential energy generated by the force storage member 132 .

[0270] In one embodiment, in step 2, when the elastic potential energy acts on the other end of the position control rod 1332, a reverse thrust elastic member 1335' is linked to generate a reaction force to reduce the tension on the unlocking valve 1333; in step 5, the position control rod 1332 is driven to reset by the reverse thrust elastic member 1335'.

[0271] In one embodiment, the reaction force generated by the reverse thrust elastic member 1335 ′ is smaller than the elastic potential energy.

[0272] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
