Description

Lock control method and lock

Technical field

This application relates to the technical field of locks, and in particular to a method for controlling locks and locks.

Background technique

At present, with the continuous development of communication technology and the continuous application in the field of electronic locks, lock control technology is constantly developing in the direction of intelligence. Users are no longer satisfied with the unlocking control of the locks, and gradually increase the requirements for the status monitoring, anti-theft, low power consumption, shell protection level, appearance, and ease of assembly of electronic locks.

In the prior art, the existing electronic locks usually need to overcome the resistance of the locking mechanism and external resistance when using a driving mechanism such as a motor to unlock. Some smart padlocks use a double solenoid driving mechanism in order to improve the anti-theft. As a result, the power consumption of the driving mechanism is relatively high, and it is difficult to ensure the long-term high-power output of electricity by wireless power supply, and the unlocking failure due to insufficient power supply of the driving mechanism may occur. However, electronic locks powered by a built-in battery will also reduce the battery life due to the high power consumption of the drive mechanism, and require battery maintenance and replacement. At the same time, it will cause problems such as high current, temperature rise, and accelerated aging of components. Electronic padlock life.

In the prior art, electronic locks that use dual solenoids or a single solenoid as the driving element have their own advantages and disadvantages: when dual solenoids are used, as long as one solenoid fails, the entire lock will fail; A single solenoid reduces the probability of failure of the lock body due to solenoid failure. For example, if two solenoids are used on a double solenoid lock, the failure rate of a single solenoid will lead to 100% of the lock failure rate. When used on two single solenoid locks, the failure rate of a single solenoid will lead to the failure rate of the lock 50%, but when a single solenoid is used, when the electronic lock is subjected to external forces such as knocking, strong vibration, beating, etc., because the solenoid core shaft has a weight, the solenoid’s return spring is relatively soft, and the solenoid The momentary retraction under the action of inertial force causes the electronic lock to be abnormally opened, thereby reducing the anti-theft performance of the electronic lock.

The application of existing electronic locks has an increasingly strong demand for state detection, especially for electronic locks used in the field of electric power error prevention. The state detection is particularly important, and the detected state of the lock is consistent with the actual state of the lock. The level requirements are extremely strict, especially the phenomenon of "false closure" is not allowed. "False closure" means that the lock status feedback on the unlocker is locked, and the real state of the lock is unlocked. Otherwise, there will be serious regulatory loopholes, which may Cause a serious electrical accident. Existing electronic locks generally use magnetic steel to cooperate with Hall elements for position detection, but the position detection accuracy of this detection method is low, which may cause "false closure" phenomenon;

For electronic locks used outdoors, the protection level of the shell is relatively high. The electronic padlock with bilateral locking is difficult to effectively isolate foreign objects such as dust and rain during the opening and closing process and in the unlocked state. When the foreign objects enter the electronic padlock It may cause the mechanical parts of the electronic padlock to jam and not operate smoothly, affecting the use experience, and even cause the mechanical parts to jam and the entire electronic padlock to fail; it will also cause the internal parts to corrode and age, and the components are short-circuited and damaged. The padlock's life is attenuated and it can't even be used normally;

Existing electronic padlocks still have a large number of parts, which increases the factors that cause failure risks. At the same time, it also reduces assembly efficiency and affects production efficiency. Some pins, plugs or screws leak on the outer surface of the electronic lock, which affects the electronics. The appearance of the lock will also provide technical enlightenment for the criminals to violently crack the electronic padlock.

Detailed ways

It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other if there is no conflict. Hereinafter, the present application will be described in detail with reference to the drawings and in conjunction with the embodiments.

It should be pointed out that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs.

In this application, unless otherwise stated, the orientation words used such as "up, down, top, bottom" are usually for the direction shown in the drawings, or for the component itself in the vertical, vertical, or horizontal direction. In terms of vertical or gravitational direction; similarly, for ease of understanding and description, "inner and outer" refers to the inner and outer relative to the contour of each component itself, but the above-mentioned orientation words are not used to limit the application.

In order to solve the problem of low detection accuracy of the lock opening and closing state in the prior art, the present application provides a lock control method and a lock.

The lock control method of this embodiment includes: the lock receives the communication instruction sent by the unlocker; the lock detects the working position of the locking assembly 30, wherein the working position of the locking assembly 30 includes the free state position and the restricted state position; according to the locking assembly 30 Whether it is in the free state position, determine whether the unlocker allows the lock to change its working state; if allowed, the lock changes its working state, and the working state of the lock is at least unlocked or locked; the lock sends the operation result to the unlocker. Through the above-mentioned lock control method, the lock can accurately detect the state of the lock when interacting with the unlocker, and feed it back into the unlocker, so that the state of the lock can be accurately detected and fed back, and the lock assembly 30 The actual position state is used as a condition for changing the state of the lock, that is, the free position state of the locking assembly 30 is used as an opportunity to start the unlocking or locking operation to ensure the accuracy and reliability of the unlocking or locking control logic.

The control method also includes: the lock sends the current working state of the lock after receiving the communication instruction and before the working state is changed to the unlocker, and the unlocker displays the current working state of the lock, so as to facilitate the operator to check the state of the lock Judgment to determine the subsequent operations that need to be performed. Under normal circumstances, before any operation is performed on the lock, the initial natural state of the lock generally includes the locked state and the unlocked state. In this embodiment, the lock obtains the current working state by detecting the lock hook 20, where the lock hook 20 is used with The locking assembly 30 cooperates to realize unlocking or locking of the lock. Specifically, when the lock is in the initial natural state, after receiving the communication instruction from the unlocker and before controlling the lock to unlock or lock, first determine the current working state of the lock: when the lock hook 20 is at the lock hook locking position, determine the lock In the locked state, when the lock hook 20 is in the unlocked position of the lock hook, it is determined that the lock is in the unlocked state.

It should be noted that the working position of the lock assembly 30 includes a free state position and a restricted state position, wherein the lock assembly can be maintained in the free state position or the restricted state position by components on the lock or external force. In this embodiment, the lock hook 20 on the lock presses the lock assembly 30, and restricts the small range movement of the lock assembly 30, so that it is in the restricted state position; after the lock hook 20 is pressed by an external force, the lock hook 20 is unlocked Due to the restriction of the assembly 30, the locking assembly 30 can move in a small range and switch from the restricted state position to the free state position. Specifically, the locking assembly 30 of this embodiment includes a sphere 31 and a lock tongue 32 that abut against each other, wherein the sphere 31 cooperates with the lock hook 20 and can extend into or out of the lock hook 20, and the state change of the drive assembly 40 can release or To limit the movement of the locking assembly 30, the driving assembly 40 includes an inner core 43, wherein the inner core 43 can extend into or out of the movement path of the lock tongue 32, so as to block the ball 31 from exiting the lock hook 20 by the stop tongue 32. In this way, when the lock assembly 30 is in the free state position, the lock assembly 30 does not limit the change of the state of the drive assembly 40, and the inner core 43 of the drive assembly 40 can move freely, thereby freely extending into or out of the movement path of the lock tongue 32, realizing the The ball 31 is locked at the position where it extends into the lock hook 20 or the ball 31 can exit the lock hook 20, which also realizes the locking and unlocking of the lock hook 20; when the lock assembly 30 is in the restricted state position, the lock assembly 30 restricts The state of the drive assembly 40 changes, the lock tongue 32 and the inner core 43 have a stop-limiting relationship, the lock tongue 32 obstructs the movement path of the inner core 43 exiting the lock tongue 32, and the inner core 43 remains in the movement path of the lock tongue 32 On the upper side, the ball 31 cannot exit the lock hook 20, so that the lock hook 20 remains locked.

In this embodiment, the detection of the lock hook 20 is based on the Hall element. When the lock hook 20 is in the locked position of the lock hook, the Hall element is in the triggered state, and when the lock hook 20 is in the unlocked position of the lock hook, The Hall element is in an untriggered state. Similarly, the detection of the latching assembly 30 is based on the microswitch as the judgment basis. When the latching assembly 30 is in the restricted state position, the microswitch is triggered by pressing, and when the latching assembly 30 is in the free state position, the microswitch is not triggered. Of course, the setting method of the micro switch can also adopt the opposite setting method, that is, the micro switch is not triggered when the locking component 30 is in the restricted state position, and the micro switch is triggered when the locking component 30 is in the free state position.

It should be noted that, since the lock of this embodiment is a padlock, the shape of the shackle 20 is U-shaped. Of course, the shape of the shackle 20 may also be a straight line or other shapes.

When permitted, the lock changes its working state, including: the lock continues to detect that the working positions of the shackle 20 and the locking assembly 30 remain unchanged for a first preset time, and after the first preset time, the drive assembly of the lock 40 Change the driving state and change the working state of the lock.

When the lock is in the locked state, when the lock hook 20 is pressed by the outside and the pressing is not removed, the working position of the lock assembly 30 will change, and the working position of the lock hook 20 will not change. The lock detects that the working position of the lock assembly 30 is restricted The state position is switched to the free state position, and the working position of the locking assembly 30 is continuously detected as the free state position for the first preset time. After the first preset time, the drive assembly 40 of the lock changes the drive state, and the lock The work status changes. It should be noted that after the drive assembly 40 of the lock changes its driving state, no matter whether the pressing on the shackle 20 is removed, the working state of the lock will change, that is, it will become an unlocked state. In this embodiment, the first preset time is set to 450 ms, so as to avoid the phenomenon of false opening when the hook 20 of the padlock is quickly removed after being pressed.

After changing its working state, the lock can have two follow-up methods,

method one

As shown in Figure 1, after the working state is changed, the control method further includes: the lock continuously detects the unlocker, and the lock detects again that the locking assembly 30 is switched from the restricted state position to the free state position, indicating that the lock hook 20 is again When pressed by an external force, the lock continuously detects that the working positions of the lock hook 20 and the locking assembly 30 remain unchanged for the second preset time, and after the second preset time, the driving state of the driving assembly 40 is changed again. In this embodiment, the second preset time is set to 100 ms. This method can realize the continuous operation of the lock, that is, the lock can be locked without pulling out the unlocker after the lock is unlocked.

Way two

As shown in Figure 2, after the working state of the lock is changed, the lock continues to detect the working positions of the shackle 20 and the locking assembly 30. When the lock detects that the working position of the locking assembly 30 is switched from the free state position to the restricted state position and then to When the free state position and the working position of the lock hook 20 are switched from the lock hook locked position to the lock hook unlocked position, the driving assembly 40 changes the driving state again, and the driving assembly 40 releases the inner core 43. In this way, the drive assembly 40 will automatically reset after the lock is unlocked, and the lock cannot be continuously locked after the lock is unlocked, and the locking operation needs to be performed again after the unlocker is pulled out, thereby improving the standardization and safety of the use of the lock.

When permitted, the lock changes its working state, including: when the current working state is the unlocked state, the drive assembly 40 of the lock changes the drive state, that is, the drive assembly 40 pulls in the inner core 43, and after changing its drive state, The lock continuously detects that the working positions of the lock hook 20 and the locking assembly 30 remain unchanged within the third preset time, indicating that the lock hook 20 has been in a state after being pressed by an external force. After the third preset time, the drive assembly 40 is again Changing the driving state means that the driving assembly 40 is powered off to release the inner core 43. In this embodiment, the third preset time is set to 100 ms. The second preset time and the third preset time can avoid the problem that the lock hook 20 pops out too quickly when the lock is unlocked, and the lock erroneously tries to change the working state and causes the structure to jam.

After the driving assembly 40 changes its driving state and before the lock continues to detect that the working positions of the lock hook 20 and the locking assembly 30 remain unchanged within the third preset time, the control method further includes: the lock detects the working position of the locking assembly 30 It is switched from the free state position to the restricted state position and then to the free state position, and it is detected that the working position of the lock hook 20 is switched from the lock hook unlocked position to the lock hook locked position.

After the driving state of the driving assembly 40 is changed again and before the operation result is sent to the unlocker, the control method further includes: the lock detects that the working positions of the lock hook 20 and the locking assembly 30 remain unchanged and continue until the fourth preset time, It means that the lock has been kept in the locked state, but has not switched to the unlocked state. After the fourth preset time, the lock is switched to the locked state, so that the locking process of the lock is completed, and then the lock sends the operation result to the unlocker. The specific duration of the fourth preset time can be set as required. In this embodiment, the fourth preset time is set to 200 ms, so as to give the inner core 43 sufficient movement time.

Taking the flowchart of FIG. 1 and the action sequence diagram of FIG. 3 as examples, the specific process of the control method of this embodiment is as follows:

The unlocker is connected to the lock. The unlocker supplies power to the lock and performs identity verification with the lock. The lock waits for a communication command from the unlocker. After the identity verification is passed, the unlocker sends a communication command to the lock. Detect the state of the Hall element, if the Hall element is triggered, the lock is in the locked state, if the Hall element is not triggered, the lock is in the unlocked state, the lock will feedback its current working state to the unlocker, and then the lock will continue to detect the micro-movement Whether the switch is triggered or not, until the lock detects that the micro switch is not triggered, the lock determines whether it needs to be locked or unlocked according to the state of the Hall element detected before;

If the Hall element is triggered and the lock needs to be unlocked, the lock will continue to detect the state of the micro switch and the Hall element before unlocking. If the micro switch remains untriggered and the Hall element remains triggered for 450ms, it means The lock has been kept pressed by external force, the lock hook 20 is in the lock hook locked position, the lock assembly 30 is in the free state position, the lock performs unlocking, the lock control drive assembly 40 is energized to attract the inner core 43, and the lock will report the result of the unlocked operation to Unlocker, unlocking is complete;

If the Hall element is not triggered, the lock needs to be locked. If the micro switch is not triggered, the lock first controls the drive assembly to energize the inner core 43, and the lock hook 20 is switched from the lock hook unlocked position to the lock hook locked position under the action of external force , The locking assembly 30 is switched from the free state position to the restricted state position and then switched back to the free state position again, the Hall element is switched from untriggered to triggered, the micro switch is switched from untriggered to triggered and then back to untriggered, the lock is detected If the Hall element remains triggered and the micro switch remains untriggered for 100ms, the lock control drive assembly 40 is powered off and releases the inner core 43. After the inner core 43 is released, the lock continues to detect that the Hall element is triggered, indicating the lock hook 20 Keep pressed by the external force, after 200ms, the lock will report the locked operation result to the unlocker, and the locking is completed;

In particular, if the lock is locked again without disconnecting the unlocker after the unlocking is completed, the lock continues to detect that the unlocker maintains communication, and the drive assembly 40 of the lock remains energized to pull in the inner core 43. When the lock is pressed by the external force again When the lock hook 20 moves from the lock hook unlocked position to the lock hook locked position, the working position of the lock assembly 30 changes from the free state position to the restricted state position and then to the free state position. The Hall element is switched from untriggered to triggered, and the micro switch Eventually, it is not triggered, indicating that the lock is pressed by an external force and the lock is locked, and the drive assembly 40 of the lock is powered off to release the inner core 43. The subsequent process is the same as the normal lock.

As shown in Figures 4 to 12, this embodiment also provides a lock, which is controlled by the above-mentioned control method. The lock includes a lock body 10, a lock hook 20, a lock assembly 30, a drive assembly 40, and a first magnetic member. 51. The first sensing element, the detecting element 52 and the electronic circuit 60. The lock hook 20 has a lock hook locking position, a lock hook pressing position, and a lock hook unlocking position. The lock hook 20 is in the lock hook locked position and the lock hook pressing position. All extend into the lock body 10, and the distance that the lock hook 20 extends into the lock body 10 when the lock hook is pressed is greater than the distance that the lock hook 20 extends into the lock body 10 when the lock hook is in the locked position, and the lock hook 20 is in the lock position. When the hook is in the unlocked position, at least one end of the lock hook 20 extends out of the lock body 10; the locking assembly 30 is movably arranged in the lock body 10 and can extend into or out of the lock hook 20 to lock or unlock the lock hook 20; At least a part of it is movably arranged in the lock body 10 and can extend into or out of the movement path of the lock assembly 30 to limit or release the movement of the lock assembly 30; the first magnetic member 51 is connected to the lock hook 20 and synchronized with the lock hook 20 Movement; the first sensing element is located in the lock body 10, and can sense the position of the first magnetic element 51, when the lock hook 20 is in the lock hook locked position or the lock hook pressing position, the first magnetic element 51 triggers the first sensing element When the lock hook 20 is in the unlocking position of the lock hook, the first magnetic member 51 does not trigger the first sensing member; the detection member 52 is located in the lock body 10, and when the lock hook 20 is in the locked position of the lock hook or in the locked position of the lock hook and During the switching process of the unlocking position of the lock hook, the lock assembly 30 is located at the restricted state position, and the lock assembly 30 triggers the detection member 52. When the lock hook 20 is located at the lock hook pressing position or the lock hook unlocking position, the lock assembly 30 is located at the free state position , The locking assembly 30 does not trigger the detection element 52; the electronic circuit 60 is arranged in the lock body 10 and is electrically connected to the drive assembly 40, the first sensing element and the detection element 52. The electronic circuit 60 is based on the first sensing element and the detection element 52 The result of the detection controls the action of the drive assembly 40.

In this embodiment, the first sensing element and the detecting element 52 are used to detect the positions of the lock hook 20 and the locking assembly 30 respectively, and the electronic circuit 60 comprehensively analyzes the detection results, and comprehensively judges the opening and closing state of the lock according to the positions of the two , So as to ensure the reliability of the lock status sent by the electronic circuit 60 to the unlocker and the operation result after the lock changes its working status, ensure the accuracy and reliability of the lock opening and closing status obtained by the operator, avoid the occurrence of false closures and other regulatory loopholes, and ensure Effective and reliable supervision of locks. In addition, the overall lock does not add too many parts, the number of parts is small, the assembly is simple, the processing is convenient and fast, and the production cost is low.

In this embodiment, the first magnetic element 51, the first induction element, and the detection element 52 constitute the detection assembly 50, wherein the first magnetic element 51 is a magnetic steel, and the first induction element is a reed switch or a Hall element. Capable of sensing the position of the first magnetic member 51, the first magnetic member 51 and the first sensing member cooperate to detect the position of the lock hook 20 to determine whether the lock hook 20 is in the lock hook locked position or the lock hook is compressed Position, when the locking hook 20 is in the locking position of the locking hook or the locking hook pressing position, as shown in Figures 5 and 7, the first magnetic element 51 triggers the first sensing element, and the first sensing element can sense the first magnetic element 51. The first sensing element is triggered. The detecting member 52 is a micro switch, which is located in the lock body 10, and the locking assembly 30 has a trigger structure for triggering the detecting member 52. The detecting member 52 is used to detect the position of the locking assembly 30 to determine whether the locking assembly 30 is in a restricted state position or The free state position. When the lock assembly 30 is in the restricted state position, the lock assembly 30 triggers the detection element 52, and the detection element 52 is in the triggered state. When the lock assembly 30 is in the free state position, the lock assembly 30 does not trigger the detection element 52, the detection element 52 is in the non-triggered state. Using micro switches and other components with high position sensing accuracy to cooperate with Hall elements and other components with low position sensing accuracy, and the two parts can be matched to accurately obtain the state of the lock. Specifically, when the first sensing part and the detecting part 52 When both are in the triggered state, the lock hook 20 is in the locked position of the lock hook or in the process of switching between the locked position of the lock hook and the unlocked position of the lock hook; when the first sensing element is in the triggered state and the detection element 52 is in the non-triggered state, the lock The hook 20 is located at the locking hook pressing position; when the first sensing member and the detecting member 52 are both in the non-triggered state, the locking hook 20 is located at the locking hook unlocking position.

It should be noted that the distance that the locking assembly 30 extends into the locking hook 20 when the locking assembly 30 is in the restricted state position is slightly smaller than the distance that the locking assembly 30 extends into the locking hook 20 when the locking assembly 30 is in the free state position. That is to say, compared to the locking position of the locking hook, when the locking hook 20 moves to the locking hook pressing position, the locking assembly 30 undergoes a slight movement, which can change the position of the trigger structure relative to the trigger end, thereby changing the detection element 52 The trigger status.

As shown in Figure 4, the side wall of the locking hook 20 is provided with an arc-shaped locking groove 21, and one end of the locking assembly 30 can extend into or out of the locking groove 21 to lock or unlock the locking hook 20 and move along the locking hook 20. The direction, that is, the up and down direction of the lock in normal use, the groove width of the locking groove 21 is greater than the distance between the two sides of the locking component 30, so that the locking component 30 still has a small range of movement space in the locking groove 21, when the lock hook 20 is located in the lock When the hook is in the locked position, the locking component 30 abuts against the lower end of the locking groove 21. When the locking hook 20 is in the locking hook pressing position, the locking component 30 is separated from the lower end of the locking groove 21, so that the locking component 30 can further extend into Closed in the groove 21.

Optionally, the locking assembly 30 includes a ball 31 and a locking tongue 32. The ball 31 can extend into or out of the lock hook 20. The ball 31 matches the shape of the locking groove 21. The ball 31 is slightly smaller than the size of the locking groove 21 to facilitate installation. Lock hook compression position; one end of the lock tongue 32 abuts the ball 31, the end of the lock tongue 32 away from the ball 31 can be engaged with the drive assembly 40, and the end of the lock tongue 32 away from the ball 31 is also connected to the third elastic member 80 By abutting, various functions of the locking assembly 30 can be exerted in this way. An avoiding structure as a triggering structure is provided on the side of the tongue 32. The avoiding structure is not limited and can be matched with the detecting member 52. In this embodiment, the avoiding structure is an avoiding groove 33; because the detecting member 52 is a micro switch Therefore, its side has a trigger end. When the lock hook 20 is in the process of switching from the lock hook pressing position to the lock hook unlocking position, the avoidance groove 33 is misaligned with the trigger end, and the side wall of the avoidance groove 33 will squeeze the trigger end. The detection element 52 is triggered, and the detection element 52 is in the triggered state; when the lock hook 20 moves to the lock hook unlocking position or the lock hook pressing position, the avoiding groove 33 is aligned with the trigger end, so that the trigger end is not triggered and the detection element 52 is in a non-triggering state. Trigger state.

As shown in Figures 5 and 8, the drive assembly 40 has a movable stop end, which can move to the movement path of the lock assembly 30 and stop the lock assembly 30 at a position that extends into the lock hook 20. The stop end has a first limit step 41, and the lock tongue 32 has a second limit step 34 at one end away from the ball 31. When the lock hook 20 is in the lock hook locking position, the stop end is located at the position of the stop lock assembly 30. The second limit step 34 extends into the movement path of the first limit step 41 and prevents the stop end from exiting the movement path of the locking assembly 30. By providing a first limit step 41 and a second limit step 34 on the stop end and the locking assembly 30, when the lock hook 20 is in the locking position of the lock hook, the first limit step 41 and the second limit step At this time, the locking assembly 30 cannot exit the lock hook 20 under the stop of the stop end, so that the lock hook 20 is kept in the locking position of the lock hook, and the second limit step 34 stops the first The movement path of the limit step 41 prevents the stop end from exiting the movement path of the locking assembly 30, so that the locking assembly 30 keeps extending into the lock hook 20. Through the above arrangement, when the lock is subjected to external force, the stop end cannot withdraw from the movement path of the locking assembly 30 under the action of inertia, thereby avoiding the lock from being struck, strong vibration, falling and other brute force cracking, the spring in the lock and other flexible The possibility of accidental unlocking caused by the failure of the connection structure ensures the safety and anti-theft of the lock.

In this embodiment, the movement trajectory line of the locking assembly 30 is perpendicular to the movement trajectory line of the stop end, and the first limit step 41 protrudes along the radial direction of the stop end, that is, the protruding direction of the first limit step 41 and the locking assembly 30 The second limit step 34 protrudes along the axial direction of the locking assembly 30, that is, the protruding direction of the second limit step 34 is perpendicular to the direction of movement of the stop end, so as to ensure that the first limit step 41 and the second limit step The stopping effect between the steps 34.

In this embodiment, the driving assembly 40 includes a solenoid 42, an inner core 43, and a first elastic member 44. The solenoid 42 is arranged in the lock body 10 and is electrically connected to the electronic circuit 60; the inner core 43 and the solenoid The tube 42 is slidably connected and can change the distance that the solenoid 42 extends. The inner core 43 extends out of one end of the solenoid 42 to the stop end. The inner core 43 moves axially under the drive of the solenoid 42 to retract the solenoid. The tube 42 exits the movement path of the locking assembly 30, and the locking assembly 30 can move freely, so that it can exit the lock hook 20 under the squeeze of the lock hook 20 to realize the unlocking of the lock hook 20; the first elastic member 44 is a spring, which The two ends respectively abut against the solenoid 42 and the inner core 43, and provide the inner core 43 with elastic force to move to the movement path of the locking assembly 30 to ensure the locking performance of the lock. Since the driving assembly 40 uses a single solenoid as the driving element, it has the advantage of low power consumption compared to a structure in which a double solenoid or a motor is used as the driving element.

It should be noted that the distance of the locking assembly 30 extending into the lock hook 20 when the locking assembly 30 is in the restricted state position is slightly smaller than the distance extending into the locking hook 20 when the locking assembly 30 is in the free state position, except for the setting mode that changes the triggering state of the detection element 52 In addition to the function, it also has the function of releasing the stop between the first limit step 41 and the second limit step 34. Specifically, when unlocking is required, the lock hook 20 is pressed down first, so that the lock hook 20 is locked by the lock hook. The position moves to the locking hook pressing position, as shown in Figures 7 and 8. At this time, the locking assembly 30 further extends into the locking hook 20. During this process, the second limit step 34 moves together and exits the first limit position. The movement path of the step 41, the second limit step 34 no longer stops the first limit step 41, and the stop end can move freely, so that it can exit the movement path of the locking assembly 30 under the drive of the solenoid 42, so that The lock assembly 30 can exit the lock hook 20 to unlock the lock hook 20.

It should be noted that when the lock hook 20 is located at the lock hook pressing position, the lock hook 20 is still locked by the locking assembly 30, that is, the lock is still in the locked state.

In this embodiment, the lock set further includes a second elastic member 70, the second elastic member 70 is a spring, both ends of which abut the lock body 10 and the lock hook 20 respectively, and provide movement for the lock hook 20 to the unlocking position of the lock hook. The elastic force of the lock hook 20 is always in the locked position of the lock hook when no external force is received. And preferably, when the lock hook 20 is in the lock hook compression position, the second elastic member 70 is compressed to the shortest length that can be reached, that is, when the lock hook 20 is pressed to the lock hook compression position by an external force, The second elastic member 70 cannot be further compressed, and the lock hook 20 cannot pass the locking hook pressing position. The purpose of this design is: when the lock is hit by a brute force cracking, assuming that there is a certain moment, the locking assembly 30 further extends In the lock hook 20, the lock hook 20 is located at the lock hook pressing position, and the inner core 43 is retracted. At this time, if there is no other restriction or other restriction conditions fail, if the second elastic member 70 can continue When compressed, the lock hook 20 can move further beyond the lock hook pressing position. When the lock hook 20 is released, the lock hook 20 moves to the lock hook locking position under the action of the second elastic member 70, and the lock hook 20 will pass the lock hook again In this way, the lock hook 20 moves back and forth once to pass through the lock hook pressing position twice, thereby increasing the possibility of accidental unlocking. With the setting method of this embodiment, the lock hook 20 is in the lock hook pressing position , The second elastic member 70 can no longer be compressed, and the lock hook 20 cannot pass the lock hook pressing position. When the lock hook 20 is released, the lock hook 20 moves to the lock hook locking position. In this way, the lock hook 20 moves back and forth only once. After the locking hook presses the position once, the possibility of accidental unlocking is greatly reduced. Of course, in other embodiments, a rigid limit structure can also be added, and the rigid limit structure restricts the lock hook 20 from continuing to descend, which can also achieve the effect of reducing the possibility of accidental unlocking.

In this embodiment, the lock also includes a third elastic member 80, the third elastic member 80 is a spring, both ends of which abut the lock body 10 and the locking assembly 30 respectively, and provide the locking assembly 30 to extend into the lock hook 20 When the lock hook 20 is pressed by an external force to move to the lock hook pressing position, the locking assembly 30 will automatically further extend into the lock hook 20 under the drive of the third elastic member 80, thereby releasing the blocking end Stop.

It should be noted that only a part of the locking groove 21 is opened along the circumferential direction of the locking hook 20, so that only when both ends of the locking hook 20 are aligned with the lock body 10, the locking hook 20 can move to the locking position of the locking hook. It avoids the false closing situation caused by the lock hook 20 only one end extends into the lock body 10 and the other end is exposed to the lock body 10, so as to ensure the reliability of the locking of the lock. Since the long hook end of the lock hook 20 of a general lock is held in the lock body 10, the matching structure between the locking groove 21 and the lock body 10 is located on the long hook end, and the second elastic member 70 also abuts At the end of the long hook end, and the short hook end, due to its short length, can move between the position of extending into and out of the lock body 10, so as to realize the lock hook 20 between the lock hook locked position and the lock hook unlocked position.

The specific unlocking and locking process of the lock in this embodiment is as follows:

Referring to Figure 5, Figure 7, Figure 9 and Figure 10 in turn, the unlocking process of the lock of this embodiment is as follows:

S1: When the initial working state of the lock is the locked state, insert the unlocker into the unlocking port, and the ball 160 fixes the unlocker in the unlocking port. The unlocker detects the second magnetic member 140, which triggers the unlocker, and the unlocker initiates pairing The lock is powered and communicates with the lock to identify the identity of the lock. When the identity of the lock is verified, the unlocker will first make a comprehensive judgment on the status information of the first sensing element and the detection element 52 sent by the electronic circuit 60. When the first sensing element and the When the detection parts 52 are in the trigger state, it is determined that the lock is in the locked state, and the unlocker displays the locked state information of the lock, and prompts the operator to press the lock hook 20;

S2: The operator presses the lock hook 20, and the lock hook 20 overcomes the elastic force of the second elastic member 70 and moves downward in a small range until the limit pin 120 abuts on the lower end surface of the limit slot 16, and the lock hook 20 is at this time. Locking hook pressing position; at the same time, the lock tongue 32 and the ball 31 sequentially move to the right in a small range under the elastic force of the first elastic member 44, and the second limit step 34 avoids the first limit step 41. At this time, the inner The core 43 is in a free state and can be retracted after the solenoid 42 is energized; at the same time, the side wall of the avoiding groove 33 of the bolt 32 is far away from the trigger end, and the detection element 52 is in the non-triggered state; although the lock hook 20 moves downward in a small range Move, but the first sensing element can still detect the first magnetic element 51, and the first sensing element is still in the triggered state; at this time, the locking hook 20 is in the locking hook pressing position; the electronic circuit 60 connects the first sensing element with the detection element 52 The status information at this time is sent to the unlocker;

S3: The unlocker makes a comprehensive judgment on the state information of the first sensing element and the detection element 52 sent by the electronic circuit 60. When the first sensing element is in the triggered state and the detection element 52 is in the non-triggered state, it is determined that the lock hook 20 is located in the lock Hook pressing position, delay a certain time, such as 450ms, continue to detect the state information of the detection assembly 50 remains unchanged, the unlocker displays the state information that the lock is compressed, the unlocker sends an unlock command to the electronic circuit 60, and the electronic circuit 60 gives The solenoid 42 is energized, and the control solenoid 42 switches from the extended state to the retracted state, the inner core 43 is no longer blocked on the retreat path of the lock tongue 32, and the lock tongue 32 can move in the lock body 10; 450ms duration Time can avoid the false opening of the lock when it is pressed quickly withdrawn;

S4: At this time, the operator releases the lock hook 20. Under the elastic force of the second elastic member 70, the lock hook 20 moves from the lock hook pressing position to the lock hook unlocking position under the elastic force of the second elastic member 70, and the ball 31 goes beyond the locking groove 21 to move toward the lock hook. Move to the left to push the lock tongue 32 to overcome the elastic force of the first elastic member 44 and move to the left. Since the inner core 43 no longer stops the lock tongue 32 from moving to the left, the ball 31 can completely escape from the locking groove 21 and move toward the unlocking ring groove. 22 mobile;

When the lock hook 20 continues to move toward the unlocking position of the lock hook under the elastic force of the second elastic member 70, the tongue 32 and the ball 31 move to the right under the elastic force of the first elastic member 44 in turn until the ball 31 is completely unlocked. In the ring groove 22; at this time, the limit pin 120 abuts on the upper end surface of the limit groove 16, and the lock hook 20 is located in the unlocking position of the lock hook; the second limit step 34 avoids the first limit step 41, and at the same time, the lock tongue The side wall of the avoidance groove 33 of 32 is far away from the trigger end, and the detection element 52 is in the non-triggered state; the short hook end is out of the blind hole 14, the lock hook 20 is in the unlock position of the lock hook, and the first magnetic element 51 cannot be detected by the first sensing element. A sensing element is in a non-triggered state;

It should be noted that when the lock hook 20 moves to the unlocking position of the lock hook, the lock hook 20 will pass through the lock hook locking position because the lock hook locking position is between the lock hook unlocking position and the lock hook pressing position. When the hook 20 passes through the locking position of the lock hook, the detection element 52 will temporarily switch from the non-triggered state to the triggered state. Until the lock hook 20 moves to the lock hook unlocking position, the detection element 52 will switch back to the non-triggered state and remain in the non-triggered state. ；

S5: The operator pulls out the unlocker, the unlocker disconnects the communication and power supply with the lock, and the inner core 43 is extended. At this time, the inner core 43 is in the extended state and is stopped on the backward path of the lock tongue 32. The lock tongue 32 can only move to the left in a small range, but cannot switch to the position of exiting the lock hook 20; the unlocking process of the lock is completed.

It should be noted that S1 and S2 of the unlocking process are interchangeable, that is, the unlocker can be inserted into the lock before the lock hook 20 is pressed, or can be inserted into the lock after the lock hook 20 is pressed.

Referring to Figure 10, Figure 9, Figure 7 and Figure 5 in turn, the locking process of the lock of this embodiment is as follows:

S1: When the initial working state of the lock is the unlocked state, insert the unlocker into the unlocking port, and the ball 160 fixes the unlocker in the unlocking port. The unlocker detects the second magnetic member 140, which triggers the unlocker, and the unlocker initiates pairing The lock is powered and communicates with the lock to identify the identity of the lock. When the identity of the lock is verified, the unlocker will first make a comprehensive judgment on the status information of the first sensing element and the detection element 52 sent by the electronic circuit 60. When the first sensing element and the When the detection parts 52 are in the non-triggered state, it is determined that the lock is in the unlocked state, and the unlocker displays the state information of the lock unlocked;

S2: The unlocker sends an unlock command to the electronic circuit 60, and the electronic circuit 60 energizes the solenoid 42.

S3: The operator presses the lock hook 20 to the bottom, the lock hook 20 overcomes the elastic force of the second elastic member 70 and moves downward, and the ball 31 moves beyond the unlocking ring groove 22 and moves to the left, thereby pushing the lock tongue 32 to overcome the first elastic member 44 Because the inner core 43 no longer stops the locking tongue 32 from moving to the left, the ball 31 can be completely separated from the unlocking ring groove 22 and move toward the locking groove 21;

When the lock hook 20 continues to overcome the elastic force of the second elastic member 70 and moves downward toward the locking hook pressing position, the lock tongue 32 and the ball 31 sequentially move to the right under the elastic force of the first elastic member 44 until the ball 31 Completely enters the locking groove 21; at this time, the second limiting step 34 avoids the first limiting step 41; at the same time, the side wall of the avoiding groove 33 of the locking tongue 32 is far away from the trigger end, and the detection member 52 is in the non-triggered state; the short hook end It is clamped in the blind hole 14, the lock hook 20 is in the lock hook compression position, the first sensing member can detect the first magnetic member 51, and the first sensing member is in the triggered state; at this time, the lock is in a compressed state; The electronic circuit 60 sends the current state information of the first sensing element and the detecting element 52 to the unlocker;

It should be noted that, similar to the unlocking process, when locking, when the lock hook 20 moves to the lock hook pressing position, the lock hook 20 will pass the lock hook locking position, and the lock hook 20 is located at the lock hook locked position and the lock hook. Between the unlocked positions and when moving to the locking position of the lock hook, the detecting member 52 is temporarily switched to the triggered state. When the locking hook 20 moves past the locking hook locking position to the locking hook pressing position, the detecting member 52 switches to the non-triggered state and is in the non-triggered state. Keep in the non-triggered state when the external force is not removed;

S4: The unlocker makes a comprehensive judgment on the state information of the first sensing element and the detection element 52 sent by the electronic circuit 60. When the first sensing element is in the triggered state and the detection element 52 is in the non-triggered state, it is determined that the lock hook 20 is in the locked state. Hook pressing position, delay a certain time, such as 100ms, continue to detect the state information of the detection assembly 50 remains unchanged, the unlocker displays the state information that the lock is compressed, the unlocker sends an unlock command to the electronic circuit 60, and the electronic circuit 60 gives The solenoid 42 is de-energized, the solenoid 42 is switched from the retracted state to the extended state, the inner core 43 is blocked on the retreat path of the bolt 32, and the bolt 32 can only move to the left in a small range, but cannot withdraw. The lock hook 20; the duration of 100ms can prevent the lock hook 20 from popping out too quickly, causing the lock to instantly detect that the first sensing element is in the triggered state and the detection element 52 is in the non-triggered state, thus powering off the solenoid 42;

S5: Extend a certain time, such as 200ms, continue to detect that the state information of the first sensing element is still in the triggered state and remain unchanged, the unlocker displays the state information that the lock is in the locked state, and prompts that the locking is successful; the 200ms duration can be the inner core 43 Sufficient exercise time;

S6: The operator releases the lock hook 20, and the lock hook 20 moves upward in a small range under the elastic force of the second elastic member 70, thereby pushing the sphere 31 to move in a small range, and the second limit step 34 of the lock tongue 32 is locked Inside the first limit step 41 of the inner core 43, at this time, the inner core 43 is restricted to the extended state and cannot be retracted, the ball 31 is restricted to the position where it extends into the lock hook 20, and the lock hook 20 is restricted to Locking position of the lock hook; at this time, the first sensing element can detect the first magnetic element 51, and the first sensing element is in the trigger state; the side wall of the avoiding groove 33 touches the trigger end, and the detection element 52 is in the trigger state;

S7: The operator pulls out the unlocker, the unlocker disconnects the communication and power supply with the lock, and completes the locking process of the lock.
