Description

Technical Field

[0001] The present invention relates to the technical field of locks, and in particular to a lock structure and a working method of the lock structure. Background Art

[0002] At present, most of the locks used in storage bags at home and abroad are card locks (such as Chinese patent CN208605052U). The card lock is installed at the connection between the lid and the body of the storage box. The unlocking method of the card lock is generally one or two of key unlocking, password unlocking, and fingerprint recognition unlocking. Most of the card locks have a simple internal structure and are generally locked by connecting an elastic rebound lock hook with a lock tongue. However, frequent vibrations will occur during the movement of the suitcase, and the vibration of the suitcase will drive the vibration of the lock hook spring, which will cause the lock hook spring to vibrate. The lock hook swings, resulting in the phenomenon of abnormal unlocking of the lock hook. If it falls or is hit, the lock is very likely to be automatically bounced open, so the impact and vibration resistance are poor. As a result, a luggage lock that can prevent the lock hook from being accidentally opened by adding a limiting structure has appeared. Some locks use an electronically controlled limiting structure (such as CN108337897B) to act on the lock hook to prevent the lock hook from swinging and improve the locking reliability of the lock hook, but both hands are required for locking, which is inconvenient to use. Some locks use a mechanical limiting structure (CN210370255U and CN 218150325 U) to act on the lock hook to prevent the lock hook from swinging and improve the locking reliability of the lock hook, but the unlocking steps are cumbersome and inconvenient to use. Summary of the invention

[0003] In view of this, the present invention provides a lock structure and a working method of the lock structure to solve the above technical problems.

[0004] To achieve the above object, the present invention provides the following technical solutions: A lock structure comprises a base and a lock tongue which can be inserted into the base, wherein the lock structure, a drive component, a control mainboard, a power supply module, a signal detection module and an information acquisition module are all arranged on the base, the signal detection module is used to detect the current working state of the lock structure, the information acquisition module is used to obtain external input information, and the control mainboard is used to control the action of the drive component. When the drive component is actuated, the lock structure can be in a free reset state which can facilitate automatic locking, or the lock structure and the lock tongue are in a separated unlocked state, or the lock structure has a certain degree of freedom of movement but cannot be separated from the lock tongue in a locked state.

[0005] Furthermore, the locking structure includes a movably installed lock buckle, which can be hooked with the lock tongue to achieve locking.

[0006] Furthermore, the lock buckle is hingedly installed, and is provided with a bayonet for inserting a lock tongue. Before the lock tongue is inserted, the lock buckle makes the bayonet face the socket direction of the base under the action of the corresponding elastic member. After the lock tongue is inserted, it can drive the lock buckle to rotate. After the lock buckle rotates a certain angle, the lock tongue and the bayonet form a hook connection, and the lock buckle can be locked in position by using the locking mechanism of the locking structure.

[0007] Furthermore, the locking mechanism includes a hinged positioning buckle, which is hooked with the locking buckle to keep the lock structure in a locked state, and the driving component can drive the positioning buckle to swing.

[0008] Furthermore, a corresponding elastic member acting on the positioning buckle is used to automatically reset the positioning buckle to the locking position.

[0009] Furthermore, the driving assembly is provided with a driving notch cooperating with the positioning buckle, and when the positioning buckle is not abutted against the driving notch, the positioning buckle is in a free reset state.

[0010] Furthermore, the driving assembly includes a motor, a gear connected to the motor, and a rack moving member meshing with the gear, and the driving notch is located on the rack moving member.

[0011] Furthermore, the rack moving part is provided with a push-opening part and a positioning part which are spaced apart, and a driving slot is formed between the push-opening part and the positioning part. When the lock structure is in a locked state, a movable gap is left between the positioning part and the positioning buckle for the positioning buckle to vibrate and swing.

[0012] Furthermore, the signal detection module is used to detect the position status of the rack moving member and / or the lock.

[0013] Furthermore, the signal detection module is one or more trigger detection devices.

[0014] Furthermore, an elastic pressing mechanism capable of extending outward is also provided on the base.

[0015] In view of the lock structure disclosed above, the present application discloses another technical solution: A working method of the lock structure as described above, the initial state is the locked state, and the specific working steps are: Step S01: Use the information acquisition module to acquire input information and transmit the input information to the control mainboard. The control mainboard judges the input information. If the information is correct, proceed to step S02; if the information is wrong, do not unlock; Step S02: Using the control mainboard to control the driving component to make the locking structure release the lock tongue. At the same time, the signal detection module determines the state of the locking structure by detecting the position state of the execution structure of the driving component, and then determines whether the lock tongue is completely released. If it is detected that the lock tongue is in an incompletely released state, step S03 is executed; if it is detected that the lock tongue is in a completely released state, step S04 is executed; Step S03: The control mainboard continues to manipulate the driving assembly until the lock tongue is completely released; Step S04: Use the signal detection module to detect the position state of the lock buckle of the locking structure to determine whether the lock tongue pops out. If the lock tongue pops out, the control main board marks it as "unlocked", and the unlocking is successful, and step S06 is executed; if the lock tongue does not pop out, the control main board marks it as "unlocked, box not opened", and step S05 is executed; Step S05: Wait until the lock tongue pops out and the lock is unlocked successfully; Step S06: The control mainboard controls the driving assembly to reset, and the locking structure automatically resets under the action of the elastic force, so that the locking structure enters a free reset state, so that it is easy to automatically lock when the lock tongue is inserted next time; Step S07: Using the signal detection module to detect the position state of the lock buckle of the locking structure to determine whether the lock tongue has been fully inserted, if it is detected that the lock tongue has been fully inserted, the control main board marks it as "locked, not locked", and executes step S08; if not, the control main board marks it as "unlocked"; Step S08: The control mainboard controls the driving component to continue resetting, and the signal detection module determines whether the locking structure locks the lock tongue by detecting the position state of the execution structure of the driving component, until it is detected that it is locked, and the control mainboard marks it as "the lock is locked successfully", completing the locking.

[0016] Furthermore, when there are two lock tongues, in step S07, if it is detected that only one side of the lock tongue is fully inserted, the control motherboard is marked as "single-side locked" and the drive component does not work; if it is detected that all the lock tongues are fully inserted, the control motherboard is marked as "locked, not locked", and step S08 is executed.

[0017] Further, in step S02 and step S08, the execution structure of the driving component is a rack moving part.

[0018] Furthermore, when unlocking, the signal detection module is triggered by the lock buckle; when locking, the signal detection module is separated from the lock buckle.

[0019] Furthermore, the current state of the lock structure identified by the control mainboard in steps S04 to S08 can be prompted by voice broadcast or light indication or by sending information to the host computer.

[0020] It can be seen from the above technical solution that the advantages of the present invention are: 1. The driving assembly can be used to put the locking structure in a free reset state or the locking structure and the lock tongue in a separated state / locked state. When the locking structure and the lock tongue are in a locked state, the lock tongue can be rigidly locked, which is more secure and reliable than the existing elastic locking.

[0021] 2. When the locking structure in the present application is in a free reset state, the lock structure can be automatically locked, making locking convenient.

[0022] 3. In this application, intelligent control is used to control the unlocking and locking of the lock, and closed-loop detection control is used to make the lock function reliable and highly secure.

[0023] 4. In this application, voice broadcast or light indication is used or information is sent to the host computer for prompting, which can accurately indicate the current status of the lock structure and facilitate user use.

[0024] In addition to the above-described purposes, features and advantages, the present invention has other purposes, features and advantages. The present invention will be further described in detail with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1 refer to Figure 1 to Figure 2 To further explain this application, Figure 1 and Figure 2 A lock structure shown in the figure includes a base 1, a lock tongue 6 that can be inserted into the base 1, and a locking structure, a driving component, a control mainboard, a power supply module, a signal detection module and an information acquisition module all arranged on the base 1. The locking structure is integrated and installed in the corresponding protective shell of the base 1. The power supply module is used to power the lock structure. The power supply module can be charged or use a battery. A power display device is also provided on the base 1. The signal detection module is used to detect the current working state of the lock structure. The information acquisition module is used to obtain external input information, such as fingerprint detection or remote control or password detection. The control mainboard uses the received input information to control the action of the driving component. When the driving component is actuated, the locking structure can be in a free reset state that can facilitate automatic locking, or the locking structure and the lock tongue are in a separated locked state, or the locking structure has a certain degree of freedom of movement but cannot be separated from the lock tongue. The locked state, wherein the structures of the control mainboard, the power supply module and the information acquisition module are prior art, and the specific technical structure can refer to the technical solutions in the prior art, such as the identity acquisition module, the power supply module, and the main controller module in CN104103112B. In the present application, the base 1 is formed by two half shells, the locking tongue 6 can be one or two, the locking structure and the locking tongue 6 are used in a one-to-one correspondence, and the driving component can be set in a one-to-one correspondence with the locking structure or synchronously drive the two locking structures to work synchronously.

[0032] In the present application, the locking structure includes a movably installed lock buckle 2, which can be hooked with the lock tongue 6 to achieve locking.

[0033] The lock buckle 2 can be slidably arranged on one side of the lock tongue 6. When the lock tongue 6 is pressed down, the lock buckle 2 can be driven to automatically retreat. Then, the corresponding elastic member acting on the lock buckle 2 is used to drive the lock buckle 2 to automatically move forward and reset, which is convenient for realizing automatic locking. The driving component directly acts on the lock buckle 2 to prevent the lock buckle 2 from accidentally retreating and unlocking after being vibrated or impacted, so that the locking is reliable. Among them, the driving component may include two cam plates arranged oppositely and coaxially. The cam plates are driven by a motor. The protrusions of the two cam plates are opposite to each other and have a certain offset along the axial direction. The extension part of the lock buckle 2 is located between the two cam plates. When the corresponding protrusion acts on the lock buckle 2, it drives the lock buckle 2 to retreat and unlock. When the other protrusion acts on the lock buckle 2, it is to prevent the lock buckle 2 from retreating and unlocking. When both protrusions do not act on the lock buckle 2, the lock buckle 2 is in a free state, which can facilitate the automatic locking of the lock buckle 2, avoiding the need for external force to continuously press the lock tongue 6 when locking, and is easy to use.

[0034] The latch 2 is then engaged with the latch 2 and the latch 6 is engaged, and the latch 2 is in an unlocked position, and the latch 2 is in an unlocked position, and the latch 2 is in an unlocked position, and the latch 6 is engaged with the latch 2 and the latch 6 is engaged.

[0035] In the present application, the elastic member acting on the lock buckle 2 is preferably a first torsion spring 4 .

[0036] When the lock buckle 2 is hingedly installed, the locking mechanism may include a slidably arranged positioning buckle 3. When the lock buckle 2 is rotated to the locking position, the positioning buckle 3 is first squeezed to make the positioning buckle 3 retreat, and then the positioning buckle 3 is reset and locked by using the elastic member acting on the positioning buckle 3. Among them, the driving assembly may include two cam plates that are relatively and coaxially arranged, the cam plates are connected to the motor, the protrusions of the two cam plates are relatively and have a certain offset along the axial direction, and the extension part of the positioning buckle 3 is located between the two cam plates, and the corresponding protrusion acts on the positioning buckle 3 to drive the positioning buckle 3 to retreat and unlock, and when the other protrusion acts on the positioning buckle 3 to prevent the positioning buckle 3 from retreating and unlocking, or the other protrusion moves to the vicinity of the positioning buckle 3 to prevent the positioning buckle 3 from retreating and unlocking, and a certain vibration and swing space can be reserved for the positioning buckle 3. When both protrusions do not act on the positioning buckle 3, the positioning buckle 3 is in a free state, which can facilitate the positioning buckle 3 to engage with the lock buckle 2 for automatic locking, avoiding the need for external force to continuously press the lock tongue 6 when locking, and is easy to use.

[0037] When the lock buckle 2 is hingedly installed, in the present application, preferably, the locking mechanism includes a hinged positioning buckle 3, which is hooked and connected with the lock buckle 2 to keep the lock structure in a locked state, and the driving component can drive the positioning buckle 3 to swing, and when the driving component drives the positioning buckle 3 to swing in a corresponding direction, the positioning buckle 3 is separated from the lock buckle 2, and the lock buckle 2 rotates under the action of the first torsion spring 4, and the lock tongue 6 is pushed out by the rotation of the bayonet to achieve unlocking; when the driving component drives the positioning buckle 3 to swing in another corresponding direction, the positioning buckle 3 is tightly hooked with the lock buckle 2 or the driving component is non-contact with the positioning buckle 3 but can prevent the positioning buckle 3 from swinging and separating from the lock buckle 2, and when the positioning buckle 3 is non-contact with the driving component, it can prevent vibration from being directly transmitted to the driving component through rigid contact, and prevent the positioning buckle 3 from swinging and separating from the lock buckle 2 after being vibrated or impacted, so that the lock structure is accidentally opened, and at the same time, it can reduce the influence of vibration on the driving component, further avoid causing damage to the driving component and affecting the locking reliability of other associated lock tongues 6, so that the locking is stable and safer.

[0038] In the present application, the corresponding elastic member acting on the positioning buckle 3 is used to automatically reset the positioning buckle 3 to the locking position, which can facilitate automatic locking and automatically lock after automatic locking, avoiding the need for external force to continuously press the lock tongue 6, and is easy to use.

[0039] Specifically, when the driving assembly is separated from the positioning buckle 3 , the positioning buckle 3 is automatically reset to the locked position under the action of the corresponding elastic member, and the elastic member acting on the positioning buckle 3 is preferably the second torsion spring 5 .

[0040] In this embodiment, the driving assembly has a driving notch that cooperates with the positioning buckle 3. When the positioning buckle 3 is not abutted against the driving notch, the positioning buckle 3 is in a free reset state.

[0041] Specifically, the connecting rod 7 connected to the positioning buckle 3 extends into the driving slot, and the width of the driving slot is greater than the width of the connecting rod 7. When the driving assembly is reset to a certain position, the connecting rod 7 will not interfere with the driving slot when it swings, thereby facilitating automatic locking.

[0042] In the present application, the driving notch may be provided on the rotating member or the translating member.

[0043] In the present application, preferably, the driving notch is arranged on the translation member.

[0044] Specifically, the driving assembly includes a motor, a gear 17 connected to the motor, and a rack moving part meshing with the gear 17. The driving notch is located on the rack moving part. The motor and the signal detection module are connected to the control main board.

[0045] Specifically, the rack moving part includes a rack portion 16 and a driving rod portion 8 connected together, the gear 17 is meshed with the sliding rack portion 16, and a driving slot is set on the driving rod portion 8, wherein the driving slot can be formed by a strip groove or a U-shaped groove combined with a shifting member or formed by two end limit portions set at intervals.

[0046] In the present application, preferably, the driving rod 8 is provided with a push-opening portion 9 and a positioning portion 10 which are spaced apart, and a driving notch is formed between the push-opening portion 9 and the positioning portion 10. The driving notch is externally placed, and it is more convenient to install with the positioning buckle 3, and when the push-opening portion 9 abuts against the connecting rod 7, the positioning buckle 3 is driven to swing so that the positioning buckle 3 is separated from the lock buckle 2; the positioning portion 10 can be close to the connecting rod 7 but does not abut against the connecting rod 7, and a certain swing gap is reserved for the swing of the connecting rod 7, but the gap cannot make the connecting rod 7 swing to the unlocking range, and when the lock structure is vibrated, the connected positioning buckle 3 and the connecting rod 7 have a certain swing space, but it can ensure that the positioning buckle 3 will not be separated from the lock buckle 2, so that the lock structure is locked reliably; when the connecting rod 7 is located in the middle position between the push-opening portion 9 and the positioning portion 10, it enters a free reset state.

[0047] In the specific embodiment of the present application, the lock tongue 6 has two, that is, the driving assembly includes two rack moving parts with parallel motion trajectories and opposite directions. The two rack moving parts cooperate with the gear 17 to realize the synchronous unlocking or locking of the two locking structures, so that the lock structure has good synchronization.

[0048] In the present application, the signal detection module is used to detect the position state of the rack moving part and / or the lock buckle 2. When the signal detection module only detects the position of the rack moving part, the state of the locking structure can be determined by judging the state of the driving component; when the signal detection module only detects the position of the lock buckle 2, the matching state of the lock tongue 6 and the lock buckle 2 can be determined; both of the above forms can only detect the ideal working state of the lock; when the signal detection module is used to detect the position state of the rack moving part and the lock buckle 2 at the same time, the lock structure can be determined by combining the information to determine whether it is in one of the states of "unlocked" or "unlocked, box not opened" or "locked, not locked" or "lock has been locked successfully" or "one-side locked", which is more convenient to use.

[0049] In the present application, the signal detection module is one or more trigger detection devices, such as a micro switch 11 or a proximity switch or a through-beam sensor.

[0050] In the present application, preferably, the signal detection module is a plurality of micro switches 11 .

[0051] Specifically, a corresponding micro switch 11 is provided on the outer side of the lock buckle 2, and corresponding micro switches 11 are provided at one end or both end limit positions of the rack moving part, respectively, which can meet the detection of the two end limit positions of the rack moving part.

[0052] Preferably, in the present application, one rack moving part cooperates with the corresponding micro switch 11 to determine whether to unlock, and another rack moving part cooperates with the corresponding micro switch 11 to determine whether to lock, and the two micro switches 11 are close to each other to make the structure compact.

[0053] In the present application, the base 1 is also provided with an elastic pressing mechanism that can extend outward. After unlocking, it is convenient to push the component connected to the lock tongue 6 outward, so that the fingers can enter between the lock tongue 6 and the base 1 to grasp and open the device.

[0054] Specifically, a push rod 12, a push spring 13 and a slide 14 are provided in the base 1. One end of the push rod 12 is slidably arranged in the slide 14 fixed in the base 1, and the other end extends out of the base 1. A step portion 15 is provided on the push rod 12. The push spring 13 is sleeved outside the push rod 12. The upper end of the push spring 13 presses the step portion 15, and the lower end presses the slide 14. The step portion 15 presses against the inner surface of the base 1 to limit the limit position of the push rod 12 moving outward. The push spring 13 is used to provide the push rod 12 with a force to move toward the outside of the base 1. When the storage bag is automatically locked, the push rod 12 will be pushed back into the base 1 by the box cover, and the push spring 13 will be compressed; and when the lock buckle 2 rotates to the unlocking position under the action of the first reset spring 4, the push rod 12 will move out of the base 1 under the drive of the push spring 13, thereby pushing open the box cover.

[0055] Embodiment 2 In view of the lock structure disclosed in the first embodiment, another technical solution is disclosed.

[0056] like Figure 3 As shown, a working method of the lock structure as described above, the initial state is the locked state, and the specific working steps are: Step S01: Use the information acquisition module to acquire input information and transmit the input information to the control mainboard. The control mainboard judges the input information. If the information is correct, proceed to step S02; if the information is wrong, do not unlock; Step S02: Using the control mainboard to control the rack moving part of the driving component to make the positioning buckle 3 of the locking structure release the lock buckle 2 of the locking structure, thereby releasing the lock tongue 6. At the same time, the signal detection module determines the state of the locking structure by detecting the position state of the rack moving part of the driving component, and then determines whether the lock tongue 6 is completely released, that is, whether the corresponding micro switch 11 detects the corresponding signal. If it is detected that the lock tongue 6 is in an incompletely released state, step S03 is executed; if it is detected that the lock tongue 6 is in a completely released state, step S04 is executed; Step S03: the control mainboard continues to manipulate the driving assembly until the lock tongue 6 is completely released, that is, until the corresponding micro switch 11 is triggered; Step S04: Use the signal detection module to detect the position state of the lock buckle 2 of the locking structure to determine whether the lock tongue 6 pops out. If the lock tongue 6 pops out, the control main board marks it as "unlocked", and the unlocking is successful, and step S06 is executed; if the lock tongue 6 does not pop out, the control main board marks it as "unlocked, box not opened", and step S05 is executed; Step S05: Wait until the lock tongue 6 pops out and the lock is unlocked successfully; Step S06: The control mainboard controls the driving assembly to reset, and the positioning buckle 3 of the locking structure automatically resets under the action of the elastic force, so that the locking structure enters a free reset state, so that it is easy to automatically lock when the lock tongue 6 is inserted next time; Step S07: Using the signal detection module to detect the position state of the lock buckle 2 of the locking structure to determine whether the lock tongue 6 has been fully inserted, if it is detected that the lock tongue 6 has been fully inserted, the control main board marks it as "locked, not locked", and executes step S08; if not, the control main board marks it as "unlocked"; Step S08: The control mainboard controls the driving component to continue resetting, and the signal detection module determines whether the locking structure locks the lock tongue 6 by detecting the position state of the rack moving part of the driving component until it detects that it is locked. The control mainboard marks it as "the lock is locked successfully" and completes the locking. When the corresponding micro switch 11 is triggered, it indicates that the positioning buckle 3 is locked, and then the lock buckle 2 is locked.

[0057] In the present application, in order to prevent the lock structure from being locked accidentally, the lock structure can be controlled to enter a locked state after unlocking, that is, the driving component locks the positioning buckle 3, and after the lock buckle 2 is pressed down, the positioning buckle 3 cannot be driven to swing to lock.

[0058] In the present application, when there are two lock tongues 6, in step S07, if it is detected that only one side of the lock tongue 6 is fully inserted, the control main board is marked as "single-side locked" and the drive component does not work; if it is detected that all the lock tongues 6 are fully inserted, the control main board is marked as "locked, not locked", and step S08 is executed.

[0059] In the present application, when unlocking, the micro switch 11 disposed on the outer periphery of the lock buckle 2 is triggered by the lock buckle 2; when locking, the micro switch 11 disposed on the outer periphery of the lock buckle 2 is separated from the lock buckle 2. Since the lock structure is in a locked state for a long time, the above principle can prevent the micro switch 11 from being triggered for a long time and affecting the service life.

[0060] In the present application, the current status of the lock structure identified by the control mainboard in steps S04 to S08 can be prompted by voice broadcast, digital display device or light indication or by sending information to the host computer, so as to facilitate the user to understand the current status of the lock structure.

[0061] The specific working process of the working method is as follows: when the lock structure receives an unlocking signal, the motor drives the driving rod 8 to move through the meshing of the rack portion 16 and the gear 17. Initially, the positioning portion 10 arranged on the driving rod 8 cancels the restriction on the positioning buckle 3, and the positioning buckle 3 enters a free reset stage separated from the driving component. The driving rod 8 continues to move so that the pushing and opening portion 9 pushes the connecting rod 7 to hinge the positioning buckle 3, and the second torsion spring 5 is deformed. The positioning buckle 3 releases the restriction on the lock buckle 2, and the lock buckle 2 rotates to the unlocking position to unlock under the action of the first torsion spring 4. After the lock tongue 6 is separated, under the control of the system, the rack portion 16 and the gear 17 drive the driving rod 8 to move in the opposite direction for a certain distance, and the pushing and opening portion 9 is out of contact with the connecting rod 7 (the positioning buckle 3 enters a stage of separation from the driving component), and the positioning buckle 3 is reset under the action of the second torsion spring 5, and is ready for automatic locking. When the lock tongue 6 is inserted, it can drive the lock buckle 2 to rotate, the first torsion spring 4 is deformed, the lock buckle 2 contacts the positioning buckle 3 to make it hinge, and under the action of the second torsion spring 5, the positioning buckle 3 reverses and restricts the lock buckle 2, thereby realizing automatic locking. After locking, the detection signal of the microswitch 11 is used under the control of the system to drive the driving rod 8 to move, and the positioning part 10 on the driving rod 8 abuts against the connecting rod 7 to limit the rotation of the positioning buckle 3, or the positioning part 10 directly moves to the vicinity of the connecting rod 7 to limit the rotation of the positioning buckle 3, or the positioning part 10 abuts against the connecting rod 7 and then retreats to reserve a swing gap for the connecting rod 7, thereby preventing the positioning buckle 3 from rotating abnormally and unlocking under impact and vibration.

[0062] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

12. A working method of the lock structure according to any one of claims 1 to 11, characterized in that: The initial state is locked, and the specific working steps are: Step S01: Use the information acquisition module to acquire input information and transmit the input information to the control mainboard. The control mainboard judges the input information. If the information is correct, proceed to step S02; if the information is wrong, do not unlock; Step S02: using the control mainboard to control the action of the driving component so that the locking structure releases the lock tongue (6); at the same time, the signal detection module uses the position state of the execution structure of the detection driving component to determine the state of the locking structure, and then determines whether the lock tongue (6) is completely released. If it is detected that the lock tongue (6) is in an incompletely released state, step S03 is executed; if it is detected that the lock tongue (6) is in a completely released state, step S04 is executed; Step S03: the control mainboard continues to manipulate the driving assembly until the lock tongue (6) is completely released; Step S04: using the signal detection module to detect the position state of the lock buckle (2) of the locking structure to determine whether the lock tongue (6) is ejected; if the lock tongue (6) is ejected, the control main board marks it as "unlocked", and the unlocking is successful, and step S06 is executed; if the lock tongue (6) is not ejected, the control main board marks it as "unlocked, box not opened", and step S05 is executed; Step S05: Wait until the lock tongue (6) pops out and the lock is unlocked successfully; Step S06: The control mainboard controls the drive assembly to reset, and the locking structure automatically resets under the action of the elastic force, so that the locking structure enters a free reset state, so that it is easy to automatically lock when the lock tongue (6) is inserted next time; Step S07: using the signal detection module to detect the position state of the lock buckle (2) of the locking structure to determine whether the lock tongue (6) has been fully inserted; if it is detected that the lock tongue (6) has been fully inserted, the control main board marks it as "locked, not locked", and executes step S08; if not, the control main board marks it as "unlocked"; Step S08: The control mainboard controls the driving component to continue resetting, and the signal detection module determines whether the locking structure has locked the lock tongue (6) by detecting the position state of the execution structure of the driving component, until it is detected that it is locked, and the control mainboard marks it as "the lock has been locked successfully", completing the locking.
