Abstract

An intelligent lock for identifying the direction of movement of a handle, comprising a fixed body that can be installed on a door leaf, a first handle, and a first linkage block that can respond to the first handle; the beneficial technical effect of the present invention is that: due to the spatial layout relationship between the first signal trigger group and the signal detection group, when the first handle moves forward or backward, the intermediate signal detector can cooperate with one of the left signal detector and the right signal detector to generate two signal groups containing different information components, including signal A and signal B or signal B and signal C, so that the movement direction of the first handle can be identified and the next operation can be determined. Secondly, the generation of the two signal groups containing different information components both utilizes the intermediate signal detector, which improves the utilization rate of the intermediate signal detector. Thirdly, since the signal group contains at least two types of signal information, it is significantly different from a single signal with only one type of signal information and has strong distinguishability.

Description

Technical Field

[0001] The present invention relates to a lock for a door leaf, and in particular to an intelligent lock capable of identifying a movement direction of a handle. Background Art

[0002] Locks are usually used in access control systems of residences and public places. The lock includes a lock tongue that can be telescopically moved to lock and open a door leaf, a transmission mechanism that can control the telescopic movement of the lock tongue, and an inner handle and an outer handle that can be connected to the transmission mechanism. In a traditional mechanical lock, the power input device is generally a lock cylinder with a lever arm. Inserting a key into the lock cylinder and twisting the lever arm can control the lock tongue to extend or retract to complete the unlocking or locking operation. In order to simplify the locking operation, in the current relatively new locks, it is not necessary to use a key operation, but to complete the locking by lifting the inner handle or outer handle, that is, lifting the inner handle or outer handle drives the lock tongue to extend through the transmission mechanism, and pressing down the inner handle can unlock at any time, and when the unlocking verification is completed, pressing down the outer handle can complete the unlocking. This method of controlling the lock tongue is very convenient and popular, so it is widely used in both mechanical locks and electric locks. However, how to identify the direction of the handle becomes the primary technical problem to be solved.

[0003] It is more common in electric locks to detect the direction of the handle through a detection element. For example, an electric lock disclosed in Chinese invention patent application 201911243810.9 includes an outer panel for installation on the outer side of the door leaf and an inner panel for installation on the inner side of the door leaf. The inner panel is rotatably provided with an inner door handle, and the inner end of the inner door handle is connected to the lock body to drive the lock tongue of the lock body to move telescopically to realize manual locking / unlocking. It also includes a signal trigger and at least two signal detection elements arranged at intervals, namely a first signal detection element and a second signal detection element, the signal trigger is a magnet, and the signal detection element is a Hall element. The first signal detection element and the second signal detection element are arranged at intervals on the plate body, and the plate body is positioned on the inner side of the inner panel by screws; the inner end of the inner door handle is provided with a turntable that can rotate with the inner door handle, and the signal trigger is arranged on the turntable. In this way, when the inner door handle is lifted, the signal trigger driven by the rotating inner door handle triggers the first signal detection component, which enables the control unit to immediately sense the door opening action inside the door and wake up; when the inner door handle is pressed down, the signal trigger driven by the rotating inner door handle triggers the second signal detection component, which enables the control unit to immediately sense that the door locking and closing action inside the door has been completed. There are many similar technical solutions, all of which use a detection component to detect a rotation of a handle and send a single signal.

[0004] On this basis, if the movement direction of other components needs to be identified, at least two additional detection components need to be provided, which will undoubtedly increase the difficulty of installation and the manufacturing cost. Moreover, when the movement direction of another handle needs to be detected, it is not a simple matter of increasing the number of detection components, which will also complicate the logic judgment process. Fig.12 As shown, it includes a fixed body 1 that can be installed on a door leaf and a circuit board 2 installed on the inner side of the fixed body 1, and a first signal detector 5a and a second signal detector 5b are arranged on the upper half of the circuit board 2, and a third signal detector 5c and a fourth signal detector 5d are arranged on the lower half. A control unit is also included, and the signal distribution signals of the above-mentioned signal detectors are connected to the control unit. A clutch is arranged between the outer handle and the inner handle, and the clutch includes an outer clutch block (not shown in the figure) that can be separated or connected and an inner clutch block 32, and the outer handle is radially linked with the outer clutch block, and the inner handle is radially linked with the inner clutch block 32. An upper signal trigger 4 is arranged on the outer clutch block, and a lower signal trigger 4a is arranged on the inner clutch block 32, wherein the upper signal trigger 4 is located between the first signal detector 5a and the second signal detector 5b, and the lower signal trigger 4a is located between the third signal detector 5c and the fourth signal detector 5d. When the clutch is in the disengaged state, when the outer handle is lifted or pressed down, the upper signal trigger 4 will trigger the first signal detector 5a and the second signal detector 5a to send signals A and B respectively; when the inner handle is lifted or pressed down, the lower signal trigger 4a will trigger the third signal detector 5c and the fourth signal detector 5d to send signals C and D respectively. When the clutch is in the combined state, when the outer handle or the inner handle is lifted up, the upper signal trigger 4 triggers the first signal detector 5a to send signal A, and the lower signal trigger 4a triggers the fourth signal detector 5d to send signal D, forming a signal group AD; when the outer handle or the inner handle is pressed down, the upper signal trigger 4 triggers the second signal detector 5b to send signal B, and the lower signal trigger 4a triggers the third signal detector 5c to send signal C, forming a signal group BC. It can be seen that this scheme will form six signals composed of different information in application, and the control unit needs to have a logical judgment program to distinguish these six signals, which is very complicated, and the bloated program design also increases the error rate. Summary of the invention

[0005] According to the disclosed contents of the prior art, it can be found that detecting the rotation direction of a handle by a signal detector is a conventional technical means, and the scalability is very poor. When it is necessary to detect the movement of other components, it is necessary to increase the signal detector accordingly. The utilization rate of the signal detector is low, which makes the detection system complicated. For this reason, it is necessary to improve the existing handle direction detection system to accurately identify the direction of the handle. Secondly, it is also hoped to improve the utilization rate of the signal detector and optimize the scalability of the handle direction detection system.

[0006] In view of the shortcomings of the prior art, the present invention proposes an intelligent lock for identifying the movement direction of a handle, comprising a fixed body that can be installed on a door leaf, a first handle that can move in a positive or negative direction relative to the fixed body with an original position as a starting point, and a first linkage block that can move in a left or right direction in response to the positive or negative movement of the first handle; the characteristics are:

[0007] A first signal trigger group and a signal detection group are interchangeably installed between the first linkage block and the fixed body, the first signal trigger group includes two left signal triggers and a right signal trigger arranged at intervals from left to right, the signal detection group includes three signal detectors arranged at intervals from each other, namely, an intermediate signal detector, a left signal detector and a right signal detector respectively arranged on the left and right sides of the intermediate signal detector, a left non-detection area is defined between the intermediate signal detector and the left signal detector, and a right non-detection area is defined between the intermediate signal detector and the right signal detector; when the first handle is in the original position, the left signal trigger is located in the left non-detection area, and the right signal trigger is located in the right non-detection area; when the first handle moves in the forward direction, the first signal trigger group can not only trigger the intermediate signal detector, but also trigger one of the left signal detector and the right signal detector; when the first handle moves in the reverse direction, the first signal trigger group can not only trigger the intermediate signal detector, but also trigger the other of the left signal detector and the right signal detector;

[0008] It also includes a control unit, which is signal-connected to the three signal detectors respectively, and the control unit can identify the movement direction of the first handle according to the signal group sequence transmitted by the three signal detectors.

[0009] The original position is the position of the moving component when the external driving force is lost. Taking the first handle as an example, when a person does not apply any external force to the first handle installed on the door leaf, the position of the first handle in a natural state is the original position.

[0010] The first handle can move in various ways, most commonly sliding back and forth along a straight line or rotating counterclockwise or clockwise around a fixed point. The movement path of the first handle is distributed on both sides of the original position.

[0011] The first linkage block and the first handle may adopt a split structure and have a motion association relationship, or the first linkage block and the first handle may adopt an integrated structure. The movement direction of the first linkage block is controlled by the first handle. When the first handle moves in the positive direction, the first linkage block moves in one of the left or right directions. When the first handle moves in the reverse direction, the first linkage block moves in the other of the left or right directions. The movement mode of the first linkage block is also diverse, for example, it may slide back and forth along a straight line or rotate back and forth to the left or right around a fixed point. The movement directions of the first handle and the first linkage block may be consistent or inconsistent, depending on the motion association relationship between them.

[0012] Among them, a first signal trigger group and a signal detection group are interchangeably installed between the first linkage block and the fixed body, and the above characteristics define that when the first linkage block is installed with the first signal trigger group, the fixed body is installed with the signal detection group; or when the fixed body is installed with the first signal trigger group, the first linkage block is installed with the signal detection group. In this way, the first signal trigger group can move relative to the signal detection group, so as to be able to approach or move away from the signal detection group. The first signal trigger group and the signal detection group cannot be installed on the first linkage block or the fixed body at the same time.

[0013] Among them, the left signal trigger, the right signal trigger and the second signal trigger to be discussed below can be a magnet that induces signal changes, and the signal detector can be a Hall element that is induced to generate a change signal; or, the above-mentioned signal trigger can be a mechanical contact arm, and the signal detector can be a travel switch that generates a change signal after being hit by the mechanical contact arm. The above-mentioned signal trigger and the signal detector can also be replaced by other existing position detection devices, which are not listed one by one. Each of the signal detectors has its own detection area, and the signal detector will only respond to a signal when the signal trigger enters its own detection area.

[0014] Among them, when the first handle is in the original position, the left signal trigger is located in the left non-detection area, and the right signal trigger is located in the right non-detection area. The above definition is the spatial layout relationship between the first signal trigger group and the signal detection group when the first handle is in the original position. The left non-detection area is the area between the detection area of ​​the middle signal detector and the detection area of ​​the left signal detector, and the right non-detection area is the area between the detection area of ​​the middle signal detector and the detection area of ​​the right signal detector. When the left signal trigger is located in the left non-detection area and the right signal trigger is located in the right non-detection area, neither the left signal trigger nor the right signal trigger can trigger any of the three signal detectors to generate a change signal.

[0015] Among them, the change signals generated by the right signal detector, the middle signal detector and the left signal detector after being triggered by the trigger are defined as signal A, signal B and signal C respectively.

[0016] Among them, when the first handle moves in the forward direction, the first signal trigger group can not only trigger the middle signal detector, but also trigger one of the left signal detector and the right signal detector. The above definition states that when the first handle moves in the forward direction, one of the left signal trigger and the right signal trigger in the first signal trigger group can trigger the middle signal detector, and the other or two of the left signal trigger and the right signal trigger can trigger one of the left signal detector and the right signal detector in turn. Therefore, when the first handle moves in the forward direction, the signal detection group will generate a signal group sequence containing signal A and signal B, or a signal group sequence containing signal B and signal C. For example, in one application, if the first handle moves in the forward direction, it will drive the first signal trigger group to move to the right, the right signal trigger triggers the right signal detector to generate signal A, the left signal trigger triggers the middle signal detector to generate signal B, and finally the signal detection group generates an AB signal group sequence. In other special applications, the left signal trigger can also pass the middle signal detector and continue to move forward to trigger the right signal detector to generate signal A; if the first handle moves in the forward direction, it will drive the signal detection group to move to the right, the right signal trigger triggers the middle signal detector to generate signal B, the left signal trigger triggers the left signal detector to generate signal C, and finally the signal detection group generates a BC signal group sequence. In other special applications, the left signal detector can also pass the left signal trigger and continue to move forward to be triggered by the right signal detector to generate signal C.

[0017] Among them, when the first handle moves in the reverse direction, the first signal trigger group can not only trigger the middle signal detector, but also trigger the other one of the left signal detector and the right signal detector. The working condition of the first signal trigger group defined above is similar to the working condition of the first signal trigger group when the first handle moves in the forward direction. The main difference is whether the left signal detector or the right signal detector is triggered. For example, the first signal trigger group triggers the left signal detector when the first handle moves in the forward direction, and triggers the right signal detector when the first handle moves in the reverse direction. Others can be understood by referring to the above discussion and will not be elaborated.

[0018] As for when the first handle moves forward or backward, whether the first signal triggering group triggers the left signal detector or the right signal detector mainly depends on whether the first signal triggering group and the signal detection group are installed on the first linkage block or the fixed body, and the movement direction of the first linkage block when the first handle moves. For example, in one application, the first signal triggering group is installed on the fixed body, and the signal detection group is installed on the first linkage block, so that when the first linkage block moves to the right in response to the forward movement of the first handle, the signal detection group also moves to the right, the left signal detector is triggered by the left signal trigger to generate signal C, the middle signal detector is triggered by the right signal trigger to generate signal B, the signal detection group generates a signal group sequence containing signal B and signal C, and the control unit can distinguish the handle movement status of the first handle forward movement according to the signal group sequence containing signal B and signal C. When the first linkage block moves to the left in response to the reverse movement of the first handle, the signal detection group generates a signal group sequence containing signal A and signal B, and the control unit can distinguish the handle movement status of the first handle reverse movement according to the signal group sequence containing signal A and signal B.

[0019] According to the above technical scheme, compared with the prior art, the beneficial technical effect of the present invention is that: due to the above-mentioned spatial layout relationship between the first signal trigger group and the signal detection group, when the first handle moves forward or backward, the intermediate signal detector can cooperate with one of the left signal detector and the right signal detector to generate two signal groups containing different information components, including signal A and signal B or signal B and signal C, so that the movement direction of the first handle can be identified and the next operation can be determined. Secondly, the generation of the two signal groups containing different information components both utilizes the intermediate signal detector, which increases the utilization rate of the intermediate signal detector. Thirdly, since the signal group contains at least two types of signal information, it is significantly different from a single signal with only one type of signal information and has strong distinguishability. Therefore, the positions of other moving components or the movement directions of other moving components can also be identified by the middle signal detector, the left signal detector and the right signal detector independently completing the detection work and generating a single signal without being confused with the signal group formed when the first handle moves in the forward and reverse directions. That is, the movement states of other moving components can be detected without adding signal detectors, which greatly improves the utilization rate of the original three signal detectors and optimizes the scalability of the handle direction detection system.

[0020] A further technical solution may be that, when the first handle is in the original position, the triggering stroke between the left signal trigger and the left signal detector is L1, the triggering stroke between the left signal trigger and the middle signal detector is L2, the triggering stroke between the right signal trigger and the middle signal detector is L3, and the triggering stroke between the right signal trigger and the right signal detector is L4, wherein L1 is equivalent to L3, and L2 is equivalent to L4. The triggering stroke refers to the distance that the signal trigger needs to move relative to the signal detector in order to trigger the signal detector. According to the above technical solution, the movement stroke and time duration of the left signal trigger triggering the left signal detector are equivalent to those of the right signal trigger triggering the middle signal detector, and similarly, the movement stroke and time duration of the left signal trigger triggering the middle signal detector are equivalent to those of the right signal trigger triggering the right signal detector. For example, in one application, when the first handle moves forward, the left signal trigger and the right signal trigger both move leftward relative to the signal detection group. When the left signal trigger triggers the left signal detector to form signal C, the right signal trigger can basically trigger the intermediate signal detector to form signal B at the same time. The control unit can basically receive the signals C and B at the same time, and accurately identify the movement direction of the first handle based on the BC signal group composed of the signals C and B. The control unit does not need to extend the receiving time to receive the complete signal group, which is beneficial to reducing the power consumption of the control unit. In addition, the control unit is not likely to misidentify the component signals in the signal group as two single signals and make misjudgments, thereby improving the accuracy of identifying the movement direction of the first handle.

[0021] A further technical solution may be that the widths of the left non-detection zone and the right non-detection zone are comparable, and when the first handle is in the original position, the left signal trigger is located at the center of the width direction of the left non-detection zone, and the right signal trigger is located at the center of the width direction of the right non-detection zone. The widths of the left non-detection zone and the right non-detection zone are the lengths measured along the movement directions of the left signal trigger and the right signal trigger, respectively (the widths of the left non-detection zone and the right non-detection zone mentioned in the text all have the above meanings). According to the above technical solution, the movement stroke and time duration of the left signal trigger to trigger the intermediate signal detector and the left signal detector are comparable, and the movement stroke and time duration of the right signal trigger to trigger the intermediate signal detector and the right signal detector are also comparable, and are suitable for smart locks with comparable forward or reverse movement strokes of the first handle.

[0022] Generally, door handles are installed on both sides of the door leaf. In order to distinguish the movement directions of the two handles respectively, a further technical solution may also include a second handle that can move in a positive or reverse direction relative to the fixed body with the original position as the starting point, and a second linkage block that can move to the left or right in response to the positive or reverse movement of the second handle, and a second signal trigger is installed on the second linkage block; when the first handle and the second handle are in the original position, the second signal trigger is located in the left non-detection area or the right non-detection area, and the second signal trigger can trigger one of the middle signal detector, the left signal detector, and the right signal detector in response to the positive or reverse movement of the second handle relative to the first handle, and the control unit can distinguish the movement directions of the first handle and the second handle according to the signal group or single signal transmitted by the three signal detectors.

[0023] The second linkage block and the second handle may adopt a split structure and have a motion association relationship, or the second linkage block and the second handle may adopt an integrated structure. The movement direction of the second linkage block is controlled by the second handle. When the second handle moves in the positive direction, the second linkage block moves in one of the left and right directions. When the second handle moves in the reverse direction, the second linkage block moves in the other direction. The movement mode of the second linkage block is also diverse, for example, it may slide back and forth along a straight line or rotate back and forth to the left or right around a fixed point. The movement directions of the second handle and the second linkage block may be consistent or inconsistent, depending on the motion association relationship between them.

[0024] According to the above technical solution, if the second signal trigger is located in the left non-detection zone when the first handle and the second handle are in the original position, then when the second handle moves forward relative to the first handle, the second signal trigger triggers one of the intermediate signal detector and the left signal detector, for example, the intermediate signal detector, to generate a single signal: signal B. Then, when the second handle moves backward relative to the first handle, the second signal trigger triggers the other of the intermediate signal detector and the left signal detector, for example, the left signal detector, to generate a single signal: signal C. Similarly, when the first handle and the second handle are in the original position, the second signal trigger is located in the right non-detection zone, then when the second handle moves forward or backward relative to the first handle, it will trigger one of the intermediate signal detector and the right signal detector to form a single signal. It can be seen that no matter whether the second handle moves forward or backward relative to the first handle, the control unit will only receive a single signal: signal A, signal B or signal C, which can not only be used to distinguish the movement direction of the second handle, but also can be distinguished from the signal group formed when the first handle moves. When the control unit receives a single signal, it can identify that the second handle is moving instead of the first handle, and then identify the movement direction of the second handle according to whether the received signal is signal A, signal B or signal C.

[0025] A further technical solution may also be that, when the first handle and the second handle are in the original position, the trigger stroke between the left signal trigger and the left signal detector is L1, the trigger stroke between the left signal trigger and the middle signal detector is L2, the trigger stroke between the right signal trigger and the middle signal detector is L3, and the trigger stroke between the right signal trigger and the right signal detector is L4; the second signal trigger is located in the left non-detection area, the trigger stroke between the second signal trigger and the left signal detector is L5, and the trigger stroke between the second signal trigger and the middle signal detector is L6, wherein L5 is equivalent to L1, and L6 is equivalent to L2; or the second signal trigger is located in the right non-detection area, the trigger stroke between the second signal trigger and the middle signal detector is L7, and the trigger stroke between the second signal trigger and the right signal detector is L8, wherein L7 is equivalent to L3, and L8 is equivalent to L4. According to the above technical solution, when the first handle and the second handle are in a linkage relationship (i.e., driving one of the handles to move can drive the other handle to move in the same direction), the second signal trigger and the left signal trigger or the right signal trigger can synchronously trigger the same signal detector, and will not continuously trigger the same signal detector in succession to cause signal confusion. At this time, the information composition of the signal group received by the control unit is consistent with the information composition of the signal group formed when only the first handle moves, and no new type of signal is formed, which is conducive to simplifying the setting of the logic judgment program in the control unit.

[0026] A further technical solution may also be that the widths of the left non-detection zone and the right non-detection zone are comparable, and when the first handle and the second handle are in their original positions, the second signal trigger is located at the center of the width direction of the left non-detection zone or the right non-detection zone. That is, L5 is comparable to L6, and L7 is comparable to L8. According to the above technical solution, when the first handle and the second handle are in their original positions, if the second signal trigger is located in the left non-detection zone, the second signal trigger triggers the moving travel and duration of the middle signal detector and the left signal detector respectively, which are comparable; similarly, if the second signal trigger is located in the right non-detection zone, the second signal trigger triggers the moving travel and duration of the middle signal detector and the right signal detector respectively, which are comparable, and are suitable for smart locks with comparable forward or reverse movement travel of the second handle.

[0027] A further technical solution may be that the first signal trigger group, the signal detection group and the second signal trigger are arranged at intervals in the up-down direction, and when viewed in the up-down direction, the first signal trigger group, the signal detection group and the second signal trigger remain on the same reference geometric line, which is a straight line or a circular line. Wherein, the left signal trigger and the right signal trigger of the first signal trigger group are located on the same spatial layer, the three signal detectors of the signal detection group are located on another spatial layer, and the second signal trigger is located on the third spatial layer. The three spatial layers are arranged up and down, so that motion interference is avoided when the first signal trigger group, the signal detection group and the second signal trigger move. In addition, the up-down direction refers to the direction perpendicular to the door leaf after the smart lock is installed on the door leaf. The above-mentioned "remaining on the same reference geometric line" means that the motion trajectory and the position when the first signal trigger group, the signal detection group and the second signal trigger are located on the reference geometric line.

[0028] A further technical solution may be that the first handle and the second handle can be rotated around point O in the positive and negative directions by angles θ respectively, the reference geometric line is a circular line, the center of the reference geometric line coincides with point O, and the center angle between two adjacent signal detectors is 2θ; when the first handle and the second handle are in the original position, the center angle between the left signal trigger and the middle signal detector is θ, the center angle between the right signal trigger and the middle signal detector is θ, and the second signal trigger overlaps with the left signal trigger or the right signal trigger up and down.

[0029] A further technical solution may also be that it includes a lock tongue capable of locking a door leaf, a square iron capable of controlling the telescopic movement of the lock tongue, and a clutch, wherein the clutch includes a first clutch block, a second clutch block, and a clutch pin for controlling the separation or connection of the first clutch block and the second clutch block, wherein the first linkage block is arranged on the first clutch block, and the second linkage block is arranged on the second clutch block; the second handle is radially linked with the square iron, the square iron is radially linked with the second clutch block, and the first clutch block is radially linked with the first handle; and further includes a driver, wherein the driver is connected to the control unit signal, and the driver is used to control the movement of the clutch pin in response to the clutch signal sent by the control unit after identifying the movement direction of the first handle and the second handle, so as to realize the separation or connection of the first clutch block and the second clutch block. Wherein, the first linkage block and the first clutch block may be a split structure or an integrated structure, and the second linkage block and the second clutch block may be a split structure or an integrated structure. According to the above technical solution, no matter whether the clutch is in a closed or disengaged state, by turning the second handle, the lock tongue can be controlled to move telescopically through the square iron, thereby completing the switching of locking or unlocking. However, only when the clutch is in a closed state, the square iron can be driven to rotate by the clutch when the first handle is turned, thereby completing the switching of locking or unlocking. In addition, the clutch state can be controlled by manipulating the rotation direction of the first handle and the second handle, thereby controlling the locking or unlocking of the smart lock.

[0030] A further technical solution may also include a mounting base, which is used to mount the first handle on the door leaf, and the fixed body is arranged on the mounting base; or, it may also include a lock body, on which a lock tongue capable of locking the door leaf is arranged, and the fixed body is arranged on the lock body.

[0031] Since the present invention has the above characteristics and advantages, it can be applied to a smart lock that identifies the movement direction of a handle. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Except for those explicitly stated to be equivalent or optional implementation schemes, the various implementation details disclosed below can be selectively applied or combined in one embodiment even if they are not directly related or synergistic in terms of function. Figures 1 to 11As shown, the present invention proposes an intelligent lock for identifying the movement direction of a handle, comprising a fixed body 11 that can be installed on a door leaf, a first handle 81 that can move in a positive or negative direction relative to the fixed body 11 with an original position as a starting point, and a first linkage block 2 that can move in a left or right direction in response to the positive or negative movement of the first handle 81; characterized in that: a first signal trigger group 4 and a signal detection group 5 are interchangeably installed between the first linkage block 2 and the fixed body 11, the first signal trigger group 4 includes two left signal triggers 41 and a right signal trigger 42 arranged at intervals on the left and right, the signal detection group 5 includes three signal detectors arranged at intervals from each other, namely, an intermediate signal detector 5b, a left signal detector 5c and a right signal detector 5a respectively disposed on the left and right sides of the intermediate signal detector 5b, a left non-detection area 51 is defined between the intermediate signal detector 5b and the left signal detector 5c, and a left non-detection area 51 is defined between the intermediate signal detector 5b and the left signal detector 5c, and a left non-detection area 51 is defined between the intermediate signal detector 5b and the left signal detector 5c. b and the right signal detector 5a define a right non-detection area 52; when the first handle 81 is in the original position, the left signal trigger 41 is located in the left non-detection area 51, and the right signal trigger 42 is located in the right non-detection area 52; when the first handle 81 moves in the forward direction, the first signal trigger group 4 can not only trigger the middle signal detector 5b, but also trigger one of the left signal detector 5c and the right signal detector 5a; when the first handle 81 moves in the reverse direction, the first signal trigger group 4 can not only trigger the middle signal detector 5b, but also trigger the other one of the left signal detector 5c and the right signal detector 5a; it also includes a control unit (not shown in the figure), which is respectively connected to the three signal detectors, and the control unit can identify the movement direction of the first handle 81 according to the signal group sequence transmitted by the three signal detectors.

[0045] The smart lock also includes a second handle 82 that can move in a positive or negative direction relative to the fixed body 11 with the original position as the starting point, and a second linkage block 321 that can move in a left or right direction in response to the positive or negative movement of the second handle 82; a second signal trigger 6 is installed on the second linkage block 321, and when the first handle 81 and the second handle 82 are in the original position, the second signal trigger 6 is located in the left non-detection area 51 or the right non-detection area 52; the second signal trigger 6 can trigger one of the middle signal detector 5b, the left signal detector 5c, and the right signal detector in response to the positive or negative movement of the second handle 82 relative to the first handle 81, and the control unit can identify the movement direction of the first handle 81 and the second handle 82 according to the signal group or single signal transmitted by the three signal detectors.

[0046] The first handle 81 and the second handle 82 can move in various ways, and the common ones are sliding back and forth along a straight line or rotating counterclockwise or clockwise around a fixed point. The movement paths of the first handle 81 and the second handle 82 are distributed on the positive and negative sides of the original position. In this embodiment, the first handle 81 and the second handle 82 can rotate back and forth around a fixed point, that is, pressing down the first handle 81 and the second handle 82 to rotate counterclockwise ( Figure 1 The first handle 81 and the second handle 82 are rotated in the direction indicated by the arrow in the middle, which is defined as the forward direction, and the first handle 81 and the second handle 82 are lifted up to rotate them clockwise (defined as the reverse direction). The smart lock includes a lock body 9, on which a lock tongue 91 capable of locking a door leaf, a square iron 92 capable of controlling the telescopic movement of the lock tongue 91, and a clutch 3 are arranged. The clutch 3 includes a first clutch block 31, a second clutch block 32, and a clutch pin 33 for controlling the separation or connection between the first clutch block 31 and the second clutch block 32. The first linkage block 2 is arranged on the first clutch block 31, and the first linkage block 2 and the first clutch block 31 are a split structure (in other embodiments, the first linkage block 2 and the first clutch block 31 can also be an integrated structure). The second linkage block 321 is arranged on the second clutch block 32, and the second linkage block 321 and the second clutch block 32 are an integrated structure (in other embodiments, the second linkage block 321 and the second clutch block 32 can also be a split structure). The second handle 82 is radially linked with the square iron 92, the square iron 92 is radially linked with the second clutch block 32, and the first clutch block 31 is radially linked with the first handle 81; a driver 7 is also included, the driver 7 is connected to the control unit signal, and the driver 7 is used to respond to the clutch signal sent by the control unit after identifying the movement direction of the first handle 81 and the second handle 82 to control the movement of the clutch pin 33 so as to achieve the separation or connection of the first clutch block 31 and the second clutch block 32. The second linkage block 321 and the driver 7 are respectively accommodated in the inner barrel cavity of the handle 811 to be discussed below. According to the above technical solution, regardless of whether the clutch 3 is in a state of separation or separation, the second handle 82 can be rotated to control the telescopic movement of the lock tongue 91 through the square iron 92, thereby completing the switching of locking or unlocking. However, only when the clutch 3 is in a closed state, the square iron 92 can be driven to rotate by the clutch 3 when the first handle 81 is rotated, thereby completing the switching of locking or unlocking, and the second handle 82 also rotates with it. In addition, the clutch state of the clutch 3 can be conditionally controlled by manipulating the rotation direction of the first handle 81 and the second handle 82, thereby controlling the locking or unlocking of the smart lock.

[0047] In conjunction with the accompanying drawings, the handle direction detection system for identifying the movement direction of the first handle 81 is further described below. The change signals generated by the right signal detector 5a, the middle signal detector 5b and the left signal detector 5c after being triggered by the trigger are defined as signal A, signal B and signal C respectively.

[0048] like Figure 1 , Fig. 9 and Fig.11As shown, the smart lock also includes a mounting base 1, which is used to mount the first handle 81 on the door leaf, and the fixed body 11 is arranged on the mounting base 1 (in other embodiments, the fixed body 11 can also be arranged on the lock body 9). In specific applications, the mounting base 1 can be locked to the door leaf by bolts. The fixed body 11 and the mounting base 1 are an integrated structure and become one of the walls of the mounting base 1 (of course, in other embodiments, the fixed body 11 and the mounting base 1 can also be a split structure, and the fixed body 11 is installed on the mounting base 1). The left signal trigger 41 and the right signal trigger 42 are magnets and are installed on the fixed body 11. During the forward and reverse rotation of the first handle 81, the left signal trigger 41 and the right signal trigger 42 remain stationary. The intermediate signal detector 5b, the left signal detector 5c and the right signal detector 5a are Hall elements and are installed on the first linkage block 2. The first linkage block 2 and the first handle 81 are of split structure and have a motion association relationship (of course, in other embodiments, the first linkage block 2 and the first handle 81 can also adopt an integrated structure). Specifically, the first linkage block 2 is a circuit board, and the circuit board is installed on the first clutch block 31. The first handle 81 includes a handle 811 and a control panel 812. The control panel 812 is used to input a verification instruction. The control panel 812 is connected to the control unit by signal. The driver 7 is also used to control the movement of the clutch pin 33 in response to the control unit verifying the signal sent by the control panel 812, so as to realize the separation or connection of the first clutch block 31 and the second clutch block 32. The handle 811 is barrel-shaped and has an inner barrel cavity, and a connecting column is arranged in the inner barrel cavity. The first clutch block 31 is locked on the connecting column by screws, so that when the first handle 81 rotates, the signal detection group 5 on the first linkage block 2 can be rotated in the same direction through the first clutch block 31 (of course, in other embodiments, the movement directions of the first handle 81 and the first linkage block 2 can also be inconsistent, depending on the movement association relationship between them). In summary, the first signal trigger group 4 is installed on the fixed body 11, and the signal detection group 5 is installed on the first linkage block 2. In this way, the first signal trigger group 4 can move relative to the signal detection group 5. Of course, in other embodiments, the first signal trigger group 4 and the signal detection group 5 can also be interchanged, that is, the first signal trigger group 4 is installed on the first linkage block 2, and the signal detection group 5 is installed on the fixed body 11. Regardless of the method used, the first signal trigger group 4 and the signal detection group 5 cannot be installed on the same component at the same time.

[0049] like Figure 1 As shown, when the first handle 81 is in the original position, the left signal trigger 41 is located in the left non-detection zone 51, and the right signal trigger 42 is located in the right non-detection zone 52. The left non-detection zone 51 is an area between the detection zone of the middle signal detector 5b and the detection zone of the left signal detector 5c, and the right non-detection zone 52 is an area between the detection zone of the middle signal detector 5b and the detection zone of the right signal detector 5a. When the left signal trigger 41 is located in the left non-detection zone 51 and the right signal trigger 42 is located in the right non-detection zone 52, neither the left signal trigger 41 nor the right signal trigger 42 can induce any of the three signal detectors to generate a change signal. Figure 3 As shown, when the first handle 81 is pressed down to rotate forward, the middle signal detector 5b moves to the right and is triggered by the right signal trigger 42 to generate signal B, and the left signal detector 5c moves to the right and is triggered by the left signal trigger 41 to generate signal C, and the signal detection group 5 generates a BC signal group consisting of signal B and signal C. Of course, in other embodiments, for some other special purpose, the first handle 81 can also continue to rotate forward, so that the left signal detector 5c passes the left signal trigger 41 and continues to move to the right and is triggered by the right signal trigger 42 to generate signal C. Figure 4 As shown, when the first handle 81 is lifted up to rotate in the reverse direction, the right signal detector 5a moves to the left and is triggered by the right signal trigger 42 to generate signal A, and the middle signal detector 5b moves to the left and is triggered by the left signal trigger 41 to generate signal B, and the signal detection group 5 generates an AB signal group consisting of signal A and signal B. Of course, in other embodiments, for some other special purpose, the first handle 81 can also continue to rotate in the reverse direction, so that the right signal detector 5a passes over the left signal trigger 41 and continues to move to the left and is triggered by the left signal trigger 41 to generate signal A.

[0050] like Fig. 9As shown, when the first handle 81 is in the original position, the trigger stroke between the left signal trigger 41 and the left signal detector 5c is L1, the trigger stroke between the left signal trigger 41 and the middle signal detector 5b is L2, the trigger stroke between the right signal trigger 42 and the middle signal detector 5b is L3, and the trigger stroke between the right signal trigger 42 and the right signal detector 5a is L4. The trigger stroke refers to the distance that the signal trigger needs to move relative to the signal detector in order to trigger the signal detector. In other embodiments, L1 and L3 may not be equal, and L2 and L4 may not be equal, for example, L1 is smaller than L3, and L2 is smaller than L4. In this way, when the first handle 81 is pressed down to rotate forward, when the left signal detector 5c moves to the right and is triggered by the left signal trigger 41 to generate signal C, the right signal trigger 42 is still in the right non-detection area 52, and the middle signal detector 5b needs to continue to move to be triggered by the right signal trigger 42 to generate signal B. The control unit needs a relatively long time to receive a complete BC signal group, and the control unit is also prone to mistakenly identify the BC signal group as two single signals, signal B and signal C, thereby misjudging the direction of the handle. In view of this, in this embodiment, L1 is equivalent to L3, and L2 is equivalent to L4. In this way, the movement stroke and duration of the left signal trigger 41 triggering the left signal detector 5c are equivalent to the movement stroke and duration of the right signal trigger 42 triggering the middle signal detector 5b. Similarly, the movement stroke and duration of the left signal trigger 41 triggering the middle signal detector 5b are also equivalent to the movement stroke and duration of the right signal trigger 42 triggering the right signal detector 5a. The control unit does not need to extend the receiving time to receive the complete signal group, which is beneficial to reducing the power consumption of the control unit. In addition, the control unit is not likely to mistakenly identify the constituent signals in the signal group as two single signals and make misjudgments, thereby improving the accuracy of distinguishing the movement direction of the first handle 81.

[0051] Furthermore, the width W1 of the left non-detection zone 51 is equivalent to the width W2 of the right non-detection zone 52. When the first handle 81 is in the original position, the left signal trigger 41 is located at the center of the width direction of the left non-detection zone 51, and the right signal trigger 42 is located at the center of the width direction of the right non-detection zone 52. According to the above technical solution, the movement stroke and duration of the left signal trigger 41 to trigger the intermediate signal detector 5b and the left signal detector 5c are equivalent, and the movement stroke and duration of the right signal trigger 42 to trigger the intermediate signal detector 5b and the right signal detector 5a are also equivalent. It is suitable for smart locks with equivalent forward or reverse movement strokes of the first handle 81. In combination with the following, Figure 1 , Figure 2 , Figure 4 , Figure 7 Table 1 and Table 1 exemplarily illustrate the switching relationship between the movement direction of the first handle and the locked and unlocked states of the smart lock.

[0052] like Figure 1 As shown, the clutch pin 33 is in the pop-up state, and the clutch 3 is in the disengaged state, that is, the first clutch block 31 and the second clutch block 32 are in the separated state, and the smart lock is in the locked state. Figure 3 As shown, pressing down the first handle 81 allows it to rotate forward. When the left signal trigger 41 triggers the left signal detector 5c to form a signal C, the right signal trigger 42 can basically trigger the middle signal detector 5b to form a signal B at the same time. The control unit can basically receive the signal C and signal B at the same time, and accurately identify that the first handle 81 is rotating forward based on the BC signal group composed of the signal C and signal B. At this time, the driver 7 responds to the clutch signal sent by the control unit and remains in its original state without action. The clutch pin 33 remains in the pop-up state, and the clutch 3 remains in the disengaged state. At this time, pressing down the first handle 81 cannot control the telescopic movement of the lock tongue 91, and the smart lock remains in the locked state. If as Figure 4 As shown, the first handle 81 is lifted to make it rotate in the reverse direction, and the control unit can basically simultaneously receive the AB signal group consisting of the signal A and the signal B to accurately identify that the first handle 81 is rotating in the reverse direction. At this time, the driver 7 controls the clutch pin 33 to pop out and hold in response to the clutch signal sent by the control unit. Since the clutch pin 33 has popped out at this time, the clutch pin 33 will remain in the popped-out state to keep the clutch 3 in the disengaged state. Pressing down the first handle 81 cannot control the telescopic movement of the lock tongue 91, and the smart lock remains in the locked state.

[0053] like Figure 2 As shown, the clutch pin 33 is in the inserted state, and the clutch 3 is in the closed state, that is, the first clutch block 31 and the second clutch block 32 are in the joint state, and the smart lock is in the unlocked state. Figure 7 As shown, the first handle 81 is pressed down to rotate it forward, and the control unit receives the BC signal group. At this time, the driver 7 responds to the clutch signal sent by the control unit and remains in its original state without action. The clutch pin 33 remains inserted, and the clutch 3 remains in the closed state. Pressing down the first handle 81 can control the telescopic movement of the lock tongue 91, and the smart lock remains in the normally open state. Figure 8As shown, the first handle 81 is lifted to rotate in the opposite direction, and the control unit receives the AB signal sequence. At this time, the driver 7 responds to the clutch signal sent by the control unit to control the clutch pin 33 to switch from the inserted state and maintain the ejected state, so that the clutch 3 switches to the disengaged state, and the smart lock switches from the normally open state to the locked state. In other embodiments, the control unit can also control the actions of other components after identifying the movement direction of the first handle 81 according to the signal sequence transmitted by the three signal detectors, such as controlling the warning light to flash and send a prompt signal, etc.

[0054] According to the above technical scheme, compared with the prior art, the beneficial technical effect of the present invention is that: due to the above-mentioned spatial layout relationship between the first signal trigger group 4 and the signal detection group 5, when the first handle 81 rotates forward or reverse, the intermediate signal detector 5b can cooperate with one of the left signal detector 5c and the right signal detector 5a to generate two signal groups containing different information components, including signal A and signal B or signal B and signal C, so that the rotation direction of the first handle 81 can be identified and the next operation can be determined. Secondly, the generation of the two signal groups both utilizes the intermediate signal detector 5b, which increases the utilization rate of the intermediate signal detector 5b. Thirdly, since the signal group contains at least two types of signal information, it is significantly different from a single signal with only one type of signal information and has strong distinguishability. Therefore, the middle signal detector 5b, the left signal detector 5c and the right signal detector 5a can also independently complete the detection work to generate a single signal to identify the position of other moving components, or the movement direction of other moving components, without being confused with the signal group formed when the first handle 81 rotates forward or reversely. That is, the movement state of other moving components can be detected without adding signal detectors, which greatly improves the utilization rate of the original three signal detectors and optimizes the scalability of the handle direction detection system.

[0055] The following is a further description of the structure for identifying the movement direction of the second handle 82. In this embodiment, an example is given in which the first handle 81 and the second handle 82 are in their original positions and the second signal trigger 6 is located in the left non-detection area 51. Figure 1 As shown in FIG. 1 , the clutch pin 33 is in an ejected state, and the clutch 3 is in an off state. Figure 5 As shown in FIG. 1 , when the second handle 82 is pressed down to rotate relative to the first handle 81 in the positive direction, the second linkage block 321 moves rightward with the second signal trigger 6, and the intermediate signal detector 5b is triggered by the second signal trigger 6 to generate a signal B. Figure 6As shown, when the second handle 82 is lifted up to rotate in the opposite direction relative to the first handle 81, the second linkage block 321 moves to the left with the second signal trigger 6, and the left signal detector 5C is triggered by the second signal trigger 6 to generate a signal C. Both signal B and signal C are single signals, which can not only be used to distinguish the movement direction of the second handle 82, but also can be distinguished from the signal group formed when the first handle 81 moves. When the control unit receives a single signal, it can identify that it is the second handle 82 that is moving instead of the first handle 81, and then identify the movement direction of the second handle 82 according to whether the received signal is signal B or signal C.

[0056] like Fig. 9 As shown, when the first handle 81 and the second handle 82 are in the original position, the second signal trigger 6 is located in the left non-detection area 51, the trigger stroke between the second signal trigger 6 and the left signal detector 5c is L5, and the trigger stroke between the second signal trigger 6 and the middle signal detector 5b is L6, where L5 is equivalent to L1, and L6 is equivalent to L2. Figure 2 As shown, the clutch 3 is in the closed state, the first handle 81 and the second handle 82 are in a linkage relationship, and the second signal trigger 6 and the left signal trigger 41 can synchronously trigger the same signal detector, and will not continuously trigger the same signal detector in succession to cause signal confusion. At this time, the control unit receives a signal group sequence, which is consistent with the information composition of the signal group sequence formed when only the first handle 81 moves, and no new type of signal is formed, which is conducive to simplifying the setting of the logic judgment program in the control unit.

[0057] Further, the width W1 of the left non-detection zone 51 is equivalent to the width W2 of the right non-detection zone 52. When the first handle 81 and the second handle 82 are in the original position, the second signal trigger 6 is located at the center of the width direction of the left non-detection zone 51. In this way, the second signal trigger 6 triggers the movement stroke and duration of the middle signal detector 5b and the left signal detector 5c respectively, which is suitable for smart locks with the same forward or reverse movement stroke of the second handle 82. (In other embodiments, when the first handle 81 and the second handle 82 are in the original position, the second signal trigger 6 is located in the right non-detection zone 52, the trigger stroke between the second signal trigger 6 and the middle signal detector 5b is L7, and the trigger stroke between the second signal trigger 6 and the right signal detector 5a is L8, where L7 is equivalent to L3, and L8 is equivalent to L4; further, the second signal trigger 6 is located at the center of the width direction of the right non-detection zone 52).

[0058] Further, the first signal trigger group 4, the signal detection group 5 and the second signal trigger 6 are arranged at intervals in the up-down direction, and when viewed in the up-down direction, the first signal trigger group 4, the signal detection group 5 and the second signal trigger 6 are maintained on the same reference geometric line, which is a circular line (in other embodiments, the reference geometric line can also be a straight line), and the center of the reference geometric line coincides with the point O. Among them, the left signal trigger 41 and the right signal trigger 42 of the first signal trigger group 4 are located on the same spatial layer, the three signal detectors of the signal detection group 5 are located on another spatial layer, and the second signal trigger 6 is located on the third spatial layer. The three spatial layers are arranged up and down, so that the first signal trigger group 4, the signal detection group 5 and the second signal trigger 6 are prevented from motion interference when they move. In addition, the up-down direction refers to the direction perpendicular to the door leaf. The above-mentioned "maintaining on the same reference geometric line" means that the motion trajectory and the position when the first signal trigger group 4, the signal detection group 5 and the second signal trigger 6 are located on the reference geometric line.

[0059] Furthermore, the first handle 81 and the second handle 82 can be rotated around the point O in the positive and negative directions by angles θ respectively, the reference geometric line is a circular line, the center of the reference geometric line coincides with the point O, the center angle between two adjacent signal detectors is 2θ, the center angle between the left signal trigger 41 and the middle signal detector 5b is θ, the center angle between the right signal trigger 42 and the middle signal detector 5b is θ, and the second signal trigger 6 overlaps with the left signal trigger 41 up and down (in other embodiments, when the second signal trigger 6' is located in the right non-detection area 52, the second signal trigger 6' overlaps with the right signal trigger 42 up and down).
