Description

Intelligent lockset capable of distinguishing motion direction of handle

Technical Field

The invention relates to a lock for a door leaf, in particular to an intelligent lock, which can distinguish the motion direction of a handle.

Background

Locks are commonly used in access control systems for residential and public areas. The lock comprises a lock tongue capable of moving telescopically to lock and unlock the door leaf, a transmission mechanism capable of controlling the lock tongue to move telescopically, and an inner handle and an outer handle which can be in transmission connection with the transmission mechanism. In a conventional mechanical lock, the power input device is generally a lock cylinder with a dial arm, and the bolt can be controlled to extend or retract by inserting a key into the lock cylinder and twisting the dial arm, so as to complete the unlocking or locking operation. In order to simplify the locking operation, in the present novel lock, the inner handle or the outer handle can be lifted up to complete the locking instead of using a key, namely, the inner handle or the outer handle is lifted up to drive the lock tongue to extend through the transmission mechanism, the inner handle can be pressed down to unlock at any time, and the outer handle is pressed down to complete the unlocking under the condition of completing the unlocking verification. The control mode of the lock tongue is very convenient and popular with the public, so that the lock tongue is widely applied to mechanical locks and electric locks. However, how to distinguish the steering of the handle becomes a technical problem to be solved firstly.

It is common in electric locks to detect the steering of the handle by means of a detection element. For example, the electric lock disclosed in chinese patent application 201911243810.9 includes an outer panel for being mounted on an outer side surface of a door leaf, and an inner panel for being mounted on an inner side surface of the door leaf, wherein an inner door handle is rotatably disposed on the inner panel, and an inner end of the inner door handle is connected to the lock body in a transmission manner to drive a lock tongue of the lock body to move in a telescopic manner, so as to realize manual locking/unlocking. The magnetic field sensor further comprises a signal trigger piece and at least two signal detection elements which are arranged at intervals, namely a first signal detection piece and a second signal detection piece, wherein the signal trigger piece is a magnet, and the signal detection pieces are Hall elements. The first signal detection piece and the second signal detection piece are arranged on the plate body at intervals, and the plate body is positioned on the inner side of the inner panel through screws; the inner side end of the inner door handle is provided with a turntable which can rotate along with the inner door handle, and the signal trigger piece is arranged on the turntable. Therefore, when the inner door handle is lifted up, the signal trigger part driven by the inner door handle rotates to trigger the first signal detection part, the control unit can immediately sense the door opening action in the door and wake up the door, and when the inner door handle is pressed down, the signal trigger part driven by the inner door handle rotates to trigger the second signal detection part, so that the control unit can immediately sense the door closing action in the door to be locked and closed. Similar solutions are numerous, all of which detect a steering of a handle and send a single signal by means of a detecting element.

On the basis, if the moving direction of other components needs to be distinguished, at least two detection pieces need to be additionally arranged, so that the installation difficulty is undoubtedly increased, and the manufacturing cost is increased. Moreover, when it is necessary to detect the direction of movement of the other handle, it is not possible to simply increase the number of the detecting members, and this also complicates the logical judgment program. For example, as shown in fig. 12, the door detector includes a fixed body 1 that can be attached to a door and a circuit board 2 that is attached to the inside of the fixed body 1, a first signal detector 5a and a second signal detector 5b that are laterally spaced are provided on the upper half side of the circuit board 2, and a third signal detector 5c and a fourth signal detector 5d that are laterally spaced are provided on the lower half side. The signal detector is connected with the control unit in a distributed signal mode. A clutch is arranged between the outer handle and the inner handle, the clutch comprises an outer clutch block (not shown in the figure) and an inner clutch block 32, the outer handle and the outer clutch block are in radial linkage, and the inner handle and the inner clutch block 32 are in radial linkage. An upper signal trigger 4 is arranged on the outer clutch plate and a lower signal trigger 4a is arranged on the inner clutch plate 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 5 d. When the clutch is in a separation state and the outer handle is respectively lifted up and pressed down, the upper signal trigger 4 respectively triggers the first signal detector 5a and the second signal detector 5a to send out a signal A and a signal B; when the inner handle is respectively lifted up and pressed down, the lower signal trigger 4a triggers the third signal detector 5C and the fourth signal detector 5D to send out a signal C and a signal D respectively. When the clutch is in a combined state, the outer handle or the inner handle is lifted upwards, the upper signal trigger 4 triggers the first signal detector 5a to send out a signal A, and simultaneously the lower signal trigger 4a triggers the fourth signal detector 5D to send out a signal D, namely a signal group AD is formed; when the outer handle or the inner handle is pressed down, the upper signal trigger 4 triggers the second signal detector 5B to send out a signal B, and simultaneously the lower signal trigger 4a triggers the third signal detector 5C to send out a signal C, so that a signal group BC is formed. It can be seen that the scheme can form six signals composed of different information in application, the control unit needs to be provided with a logic judgment program for distinguishing the six signals, the control unit is very complex, and the error rate is improved due to the overstaffed program design.

Disclosure of Invention

According to the disclosure of the prior art, it can be found that the conventional technical means for detecting a rotation direction of a handle by a signal detector is very poor in expansibility, and when the movement condition of other components needs to be detected, the signal detector needs to be added correspondingly, so that the utilization rate of the signal detector is low, and the detection system is complicated. Therefore, the existing handle direction-sensing detection system has to be improved to accurately identify the steering direction of the handle. It is further desirable to improve the utilization of signal detectors and to optimize the scalability of the handle-sensing system.

The invention provides an intelligent lockset for distinguishing the movement direction of a handle, aiming at the defects of the prior art, and comprising a fixed body which can be arranged on a door leaf, a first handle which can move in the positive and negative directions relative to the fixed body by taking an original position as a starting point, and a first linkage block which can respond to the positive or negative movement of the first handle and move in the left or right direction; the method is characterized in that:

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 comprises a left signal trigger and a right signal trigger which are arranged at left and right intervals, the signal detection group comprises three signal detectors which are arranged at intervals, namely a middle signal detector, a left signal detector and a right signal detector which are respectively arranged at the left side and the right side of the middle signal detector, a left non-detection area is defined between the middle signal detector and the left signal detector, and a right non-detection area is defined between the middle signal detector and the right signal detector; when the first handle is in a home position, the left signal trigger is located within the left non-detection zone and the right signal trigger is located within the right non-detection zone; when the first handle moves towards the positive direction, the first signal trigger group can trigger not only the middle signal detector but also one of the left signal detector and the right signal detector; when the first handle moves in the reverse direction, the first signal trigger set can trigger not only the middle signal detector but also the other of the left signal detector and the right signal detector;

the control unit is in signal connection with the three signal detectors respectively and can distinguish the movement direction of the first handle according to signal groups transmitted by the three signal detectors.

Wherein the original position is a position where the moving member is located when the driving external force is lost. Taking the first handle as an example, when no external force is applied to the first handle mounted on the door leaf by a hand, the position of the first handle in a natural state is the original position.

The first handle can be moved in various manners, and the first handle can slide back and forth along a straight line or rotate around a fixed point anticlockwise and clockwise. The motion paths of the first handle are distributed on the front side and the back side of the original position.

The first linkage block and the first handle can adopt a split structure and have a motion association relationship, or the first linkage block and the first handle adopt an integrated structure. The motion direction of the first linkage block is controlled by the first handle, when the first handle moves towards the positive direction, the first linkage block moves towards one of the left direction and the right direction, and when the first handle moves towards the negative direction, the first linkage block moves towards the other one of the left direction and the right direction. The motion mode of the first linkage block is also various, for example, the first linkage block can slide back and forth along a straight line or rotate back and forth around a fixed point to the left and the right. The moving directions of the first handle and the first linkage block can be consistent or inconsistent, depending on the motion correlation relationship between the first handle and the first linkage block.

The first linkage block is provided with a first signal trigger group and a signal detection group, and the first linkage block is provided with a first signal trigger group and a second signal trigger group; or when the fixed body is provided with the first signal trigger group, the first linkage block is provided with the signal detection group. In this way, the first signal trigger group can move relative to the signal detection group, and thus can move closer to or farther away from the signal detection group. The first signal trigger group and the signal detection group cannot be simultaneously mounted on the first linkage block or the fixed body.

Wherein the left signal trigger, the right signal trigger and a second signal trigger to be discussed below can be magnet pieces inducing signal change, and the signal detector can be a hall element induced to generate a change signal; alternatively, the signal trigger may be a mechanical contact arm, and the signal detector may be a travel switch which generates a change signal after being collided by the mechanical contact arm. The signal trigger and the signal detector can be replaced by other existing position detection devices, which are not listed. Each of the signal detectors has its own detection zone, and the signal detector only responds to a signal when the signal trigger enters its own detection zone.

Wherein, when the first handle is at 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, which defines the spatial layout relationship between the first signal trigger set and the signal detection set when the first handle is at the original position. The non-detection area on the left side is the area that is located between the detection area of middle signal detector and the detection area of left signal detector, the non-detection area on the right side is the area that is located between the detection area of middle signal detector and the detection area of right signal detector, when left signal trigger is located in the non-detection area on the left side, right signal trigger is located in the non-detection area on the right side, left signal trigger, right signal trigger can not trigger three any of signal detector produces the change signal.

Wherein, the change signals generated after the right signal detector, the middle signal detector and the left signal detector are triggered by the trigger are defined as a signal A, a signal B and a signal C in sequence.

Wherein, when the first handle moves towards the positive direction, the first signal trigger group can trigger not only the middle signal detector but also one of the left signal detector and the right signal detector. It is defined above that when the first handle is moved in the forward direction, it may be that one of the left signal trigger and the right signal trigger in the first signal trigger set triggers the intermediate signal detector, and the other or both of the left signal trigger and the right signal trigger in turn triggers one of the left signal detector and the right signal detector. So when the first handle is moved in the forward direction, the signal detection group will generate a signal group column containing signal a and signal B, or a signal group column containing signal B and signal C. For example, in one application, if the first handle moves in a forward direction to bring the first signal trigger set to move in a right direction, the right signal trigger triggers the right signal detector to generate a signal a, the left signal trigger triggers the middle signal detector to generate a signal B, and finally the signal detection set generates an AB signal set column, in other special applications, the left signal trigger can also trigger the right signal detector to generate a signal a after passing through the middle signal detector; if the first handle moves towards the positive direction to drive the signal detection group to move towards the right, the right signal trigger triggers the middle signal detector to generate a signal B, the left signal trigger triggers the left signal detector to generate a signal C, and finally the signal detection group generates a signal BC signal group column.

Wherein, when the first handle moves in a reverse direction, the first trigger set is capable of triggering not only the middle signal detector but also the other of the left signal detector and the right signal detector, and the operation of the first trigger set is similar to that of the first trigger set when the first handle moves in a forward direction, and the main difference is that the left signal detector or the right signal detector is triggered, for example, the first trigger set is triggered by the left signal detector when the first handle moves in the forward direction, and is triggered by the right signal detector when the first handle moves in the reverse direction. Others may be understood with reference to the above discussion and are not repeated.

When the first handle moves towards the positive direction and the negative direction, the first signal trigger group triggers the left signal detector or the right signal detector, and the first signal trigger group and the signal detection group are mainly determined by the fact that the first signal trigger group and the signal detection group are installed on the first linkage block or the fixed body, and the moving direction of the first linkage block when the first handle moves. For example, in one application, the first signal trigger set is mounted on the fixed body, and the signal detection set is mounted on the first linkage block, so that when the first linkage block moves towards the right in response to the forward movement of the first handle, the signal detection set also moves towards the right, the left signal detector is triggered by the left signal trigger to generate a signal C, the middle signal detector is triggered by the right signal trigger to generate a signal B, the signal detection set generates a signal set column containing signals B and C, and the control unit can distinguish the handle movement condition according to the signal set column containing signals B and C as follows: the first handle moves in a forward direction. When the first linkage block moves towards the left in response to the reverse movement of the first handle, the signal detection group generates a signal group column containing signals A and B, and the control unit can distinguish the handle movement condition according to the signal group column containing the signals A and B as follows: the first handle moves in a reverse direction.

According to the technical scheme, compared with the prior art, the invention has the beneficial technical effects that: due to the spatial layout relationship between the first signal trigger group and the signal detection group, when the first handle moves towards the forward direction or the reverse direction, the middle signal detector can respectively cooperate with one of the left signal detector and the right signal detector to generate two signal group columns containing different information of a signal A and a signal B or a signal B and a signal C, so that the moving direction of the first handle can be distinguished, and then the next operation can be determined. Secondly, the generation of two signal arrays containing different information components both makes use of the intermediate signal detector, providing a utilization of the intermediate signal detector. Thirdly, the signal array contains at least two kinds of signal information, and the signal array has obvious difference from a single signal with only one kind of signal information and is strong in distinguishability. Therefore, the positions of other moving components or the moving directions of other moving components can be distinguished in a mode that the middle signal detector, the left signal detector and the right signal detector independently complete detection work to generate single signals, and the signals are not mixed with the signal arrays formed when the first handle moves towards the positive direction and the negative direction, namely, the moving states of other moving components can be detected on the basis of not increasing the number of the signal detectors, the utilization rate of the three original signal detectors is greatly improved, and the expansibility of the handle distinguishing detection system is optimized.

Further technical solution may also be that, when the first handle is at the original position, a trigger stroke between the left signal trigger and the left signal detector is L1, a trigger stroke between the left signal trigger and the middle signal detector is L2, a trigger stroke between the right signal trigger and the middle signal detector is L3, and a trigger stroke between the right signal trigger and the right signal detector is L4, where L1 is equivalent to L3, and L2 is equivalent to L4. The trigger stroke refers to a distance that the signal trigger needs to move relative to the signal detector in order to trigger the signal detector. According to the technical scheme, the left signal trigger triggers the left signal detector, the moving stroke and the time duration of the right signal trigger triggering the middle signal detector are equivalent, and the moving stroke and the time duration of the right signal trigger triggering the middle signal detector are equivalent. For example, in one application, when the first handle moves towards the forward direction, the left signal trigger and the right signal trigger both move towards the left relative to the signal detection group, when the left signal trigger triggers the left signal detector to form a signal C, the right signal trigger can trigger the middle signal detector to form a signal B at substantially the same time, and the control unit can receive the signals C and B at substantially the same time and accurately distinguish the moving direction of the first handle according to a BC signal group column formed by the signals C and B. The control unit does not need to prolong the receiving time for receiving the complete signal array, so that the power consumption of the control unit is reduced, in addition, the control unit is not easy to wrongly identify the composition signals in the signal array into two single signals to cause misjudgment, and the accuracy rate of identifying the motion direction of the first handle is improved.

Further, according to a further technical solution, the widths of the left non-detection area and the right non-detection area are equal, and when the first handle is at the home position, the left signal trigger is located at the center of the left non-detection area in the width direction, and the right signal trigger is located at the center of the right non-detection area in the width direction. The widths of the left non-detection area and the right non-detection area are lengths measured along the moving direction of the left signal trigger and the right signal trigger respectively (the widths of the left non-detection area and the right non-detection area mentioned herein are all defined as above). According to the technical scheme, the left signal trigger triggers the moving strokes and the time duration of the middle signal detector and the left signal detector respectively, and the moving strokes and the time duration of the middle signal detector and the right signal detector respectively trigger by the right signal trigger are also equivalent, so that the intelligent lockset is suitable for the intelligent lockset with the equivalent forward or reverse direction moving strokes of the first handle.

Generally, door handles are respectively installed on the inner side and the outer side of a door leaf, in order to be able to respectively distinguish the moving directions of the two handles, a further technical scheme may also be that the door leaf further comprises a second handle which can move in the positive direction and the negative direction relative to the fixed body by taking the original position as a starting point, and a second linkage block which can move in the left direction or the right direction in response to the positive direction or the negative direction movement of the second handle, wherein 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 positioned in the left non-detection area or the right non-detection area, the second signal trigger can respond to the forward or backward movement of the second handle relative to the first handle to trigger one of the middle signal detector, the left signal detector and the right signal detector, and the control unit can distinguish the movement direction of the first handle and the second handle according to signal groups or single signals transmitted by the three signal detectors.

The second linkage block and the second handle can adopt a split structure and have a motion association relationship, or the second linkage block and the second handle adopt an integrated structure. The moving direction of the second linkage block is controlled by the second handle, when the second handle moves towards the positive direction, the second linkage block moves towards one of the left direction or the right direction, and when the second handle moves towards the negative direction, the second linkage block moves towards the other direction. The motion mode of the second linkage block is also various, and for example, the second linkage block can slide left and right back and forth along a straight line or rotate left and right back and forth around a fixed point. The moving directions of the second handle and the second linkage block can be consistent or inconsistent depending on the moving association relationship between the second handle and the second linkage block.

According to the above technical solution, if the second signal trigger is located in the left non-detection area when the first handle and the second handle are in the original positions, when the second handle moves in the forward direction relative to the first handle, the second signal trigger triggers one of the middle signal detector and the left signal detector, for example, the middle signal detector generates a single signal: signal B, then when the second handle is moved in the reverse direction relative to the first handle, the second signal trigger triggers the other of the middle signal detector and the left signal detector, for example the left signal detector, to generate a single signal: signal C. Also when the first and second handles are in the home position, the second signal trigger is located in the right non-detection zone, and then one of the middle and right signal detectors will be triggered to form a single signal when the second handle is moved in a forward or reverse direction relative to the first handle. It can be seen that the control unit receives only a single signal whether the second handle is moving in the forward direction or in the reverse direction relative to the first handle: the signal A, the signal B or the signal C can be used for distinguishing the moving direction of the second handle and can also be distinguished from a signal array formed when the first handle moves. When the control unit receives a single signal, it can identify the second handle instead of the first handle, and then identify the moving direction of the second handle according to whether the signal A, the signal B or the signal C is received.

Further technical solutions may also be that, when the first handle and the second handle are in the original positions, a trigger stroke between the left signal trigger and the left signal detector is L1, a trigger stroke between the left signal trigger and the middle signal detector is L2, a trigger stroke between the right signal trigger and the middle signal detector is L3, and a 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 travel between the second signal trigger and the left signal detector is L5, the trigger travel 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 travel between the second signal trigger and the middle signal detector is L7, the trigger travel 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 technical scheme, when the first handle and the second handle are in linkage relation (namely one handle is driven to move, the other handle can be driven 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 signal confusion caused by the fact that the same signal detector is triggered discontinuously and successively is avoided. At this time, the information composition of the signal array received by the control unit is consistent with the information composition of the signal array formed only when the first handle moves, and no new type of signal is formed, so that the setting of a logic judgment program in the control unit is simplified.

Further, according to a further technical solution, the widths of the left non-detection area and the right non-detection area are equal, and when the first handle and the second handle are at the original positions, the second signal trigger is located at a central position in the width direction of the left non-detection area or the right non-detection area. That is, L5 corresponds to L6, and L7 corresponds to L8. According to the technical scheme, when the first handle and the second handle are located at original positions, if the second signal trigger is located in the left non-detection area, the second signal trigger respectively triggers the moving strokes of the middle signal detector and the left signal detector, and the time duration is equivalent; similarly, if the second signal trigger is located in the right non-detection area, the second signal trigger respectively triggers the moving strokes and the time duration of the middle signal detector and the right signal detector are also equivalent, and the intelligent lock is suitable for the intelligent lock with the equivalent forward or reverse moving stroke of the second handle.

The first signal trigger group, the signal detection group and the second signal trigger are arranged at intervals in the vertical direction, and when viewed in the vertical direction, the first signal trigger group, the signal detection group and the second signal trigger are kept on the same reference geometric line, and the reference geometric line is a straight line or a circular line. 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 the other spatial layer, the second signal trigger is located on the third spatial layer, and the three spatial layers are arranged up and down, so that motion interference when the first signal trigger group, the signal detection group and the second signal trigger move is avoided. In addition, the up-down direction is a direction perpendicular to the door leaf after the intelligent lock is installed on the door leaf. The above "remaining on the same reference geometric line" means that the motion trajectories and positions of the first signal trigger group, the signal detection group and the second signal trigger when the first signal trigger group, the signal detection group and the second signal trigger are still all located on the reference geometric line.

The first handle and the second handle can rotate around an O point by a rotation angle theta in the positive direction and the negative direction respectively, the reference geometric line is a circular line, the circle center of the reference geometric line is coincident with the O point, and the circle center angle between two adjacent signal detectors is 2 theta; when the first handle and the second handle are in the original positions, a central angle between the left signal trigger and the middle signal detector is theta, a central angle between the right signal trigger and the middle signal detector is theta, and the second signal trigger is overlapped with the left signal trigger or the right signal trigger up and down.

The technical scheme includes that the door lock further comprises a spring bolt capable of locking a door leaf, square iron capable of controlling the spring bolt to move in a telescopic mode and a clutch, wherein the clutch comprises a first clutch block, a second clutch block and a clutch pin for controlling the first clutch block and the second clutch block to be separated or combined, 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; the driver is in signal connection with the control unit and is used for responding to a clutch signal sent by the control unit after the control unit distinguishes the motion direction of the first handle and the second handle to control the movement of the clutch pin so as to realize the separation or combination of the first clutch block and the second clutch block. The first linkage block and the first clutch block can be of a split structure or an integrated structure, and the second linkage block and the second clutch block can be of a split structure or an integrated structure. According to the technical scheme, the bolt can be controlled to stretch and move through the square iron by rotating the second handle no matter the clutch is in a separation or combination state, so that the locking or unlocking switching is completed. But only when the clutch is in a closed state, the first handle can drive the square iron to rotate through the clutch when being rotated, and then the switching of locking or unlocking is completed. In addition, the clutch state of the clutch can be controlled by controlling the rotation direction of the first handle and the second handle, so that the intelligent lock is controlled to be locked or unlocked.

The door comprises a door leaf, a first handle, a fixing body and a second handle, wherein the door leaf is provided with a door leaf opening, the first handle is arranged on the door leaf, and the fixing body is arranged on the door leaf opening; and the lock body is provided with a bolt capable of locking a door leaf, and the fixing body is arranged on the lock body.

Due to the characteristics and the advantages, the intelligent lock can be applied to an intelligent lock for distinguishing the movement direction of the handle.

The intelligent lock further comprises a second handle 82 capable of moving in the forward and backward directions from the original position as a starting point relative to the fixed body 11, and a second linkage block 321 capable of moving in the left or right direction in response to the forward or backward 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 positions, 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 forward or reverse movement of the second handle 82 relative to the first handle 81, and the control unit can distinguish the movement direction of the first handle 81 and the second handle 82 according to the signal group or the single signal transmitted by the three signal detectors.

The movement of the first handle 81 and the second handle 82 can be varied, and it is common to slide back and forth along a straight line or rotate counterclockwise and clockwise around a fixed point. The moving paths of the first handle 81 and the second handle 82 are distributed on the front and back sides of the original position. In this embodiment, the first handle 81 and the second handle 82 are respectively capable of rotating back and forth around a fixed point, i.e., a point O, by pressing the first handle 81 and the second handle 82 downward to rotate them counterclockwise (the direction indicated by the arrow in fig. 1 is defined as a forward direction), and lifting the first handle 81 and the second handle 82 upward to rotate them clockwise (the direction defined as a reverse direction). The intelligent lockset comprises a lock body 9, wherein a lock tongue 91 capable of locking a door leaf, a square iron 92 capable of controlling the lock tongue 91 to stretch and move and a clutch 3 are arranged on the lock body 9, the clutch 3 comprises a first clutch block 31, a second clutch block 32 and a clutch pin 33 for controlling the first clutch block 31 and the second clutch block 32 to separate or combine, the first linkage block 2 is arranged on the first clutch block 31, and a split structure is arranged between the first linkage block 2 and the first clutch block 31 (in other implementation modes, the first linkage block 2 and the first clutch block 31 can also be of an integrated structure). The second coupling block 321 is disposed on the second clutch block 32, and the second coupling block 321 and the second clutch block 32 are integrated (in other embodiments, the second coupling block 321 and the second clutch block 32 may be separated). 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; the clutch device further comprises a driver 7, the driver 7 is in signal connection with a control unit, and the driver 7 is used for controlling the movement of the clutch pin 33 to realize the separation or the combination of the first clutch block 31 and the second clutch block 32 by responding to a clutch signal sent by the control unit after the control unit distinguishes the movement direction of the first handle 81 and the second handle 82. The second linkage block 321 and the driver 7 are respectively received in inner barrel cavities of the handle 811, which will be discussed below. According to the above-described configuration, regardless of whether the clutch 3 is in the disengaged or engaged state, the locking tongue 91 is controlled to extend and contract by rotating the second handle 82 through the square iron 92, thereby completing the switching between locking and unlocking. However, only when the clutch 3 is in the closed state, the first handle 81 can be rotated to drive the square iron 92 to rotate through the clutch 3, so that the locking or unlocking is switched, and meanwhile, the second handle 82 also rotates along with the rotation. In addition, the locking or unlocking of the intelligent lock can be controlled by conditionally controlling the clutch state of the clutch 3 by manipulating the rotation directions of the first handle 81 and the second handle 82.

The handle direction-sensing system for sensing the moving direction of the first handle 81 will be further described with reference to the drawings. Wherein, the change signals generated after the right signal detector 5a, the middle signal detector 5B and the left signal detector 5C are triggered by the trigger are defined as a signal a, a signal B and a signal C in sequence.

As shown in fig. 1, 9 and 11, the intelligent lock further includes a mounting base 1, the mounting base 1 is used for mounting the first handle 81 on the door leaf, and the fixing body 11 is disposed on the mounting base 1 (in other embodiments, the fixing body 11 may also be disposed on the lock body 9). The mounting base 1 can be locked to the door leaf by means of bolts in the specific application. The fixing body 11 and the mounting base 1 are integrally formed, and are one of the wall bodies of the mounting base 1 (in other embodiments, the fixing body 11 and the mounting base 1 may be separately formed, and the fixing body 11 is mounted on the mounting base 1). The left signal trigger 41 and the right signal trigger 42 are respectively magnets and are mounted on the fixed body 11, and the left signal trigger 41 and the right signal trigger 42 are kept in a static state in the process that the first handle 81 rotates forwards and backwards. The middle signal detector 5b, the left signal detector 5c and the right signal detector 5a are hall elements, respectively, and are mounted on the first linkage block 2. The first linkage block 2 and the first handle 81 are of a split structure and have a motion correlation (of course, in other embodiments, an integrated structure may also be adopted between the first linkage block 2 and the first handle 81), specifically, the first linkage block 2 is a circuit board 2, and the circuit board 2 is mounted on the first clutch block 31. The first handle 81 comprises a handle 811 and a control panel 812, the control panel 812 is used for inputting a verification instruction, the control panel 812 is in signal connection with the control unit, and the driver 7 is further used for controlling the movement of the clutch pin 33 after the control unit verifies a signal transmitted by the control panel 812 so as to realize the separation or combination of the first clutch piece 31 and the second clutch piece 32. The handle 811 is barrel-shaped and has an inner barrel cavity, a connecting column is arranged in the inner barrel cavity, and the first clutch block 31 is locked on the connecting column through a screw, so that when the first handle 81 rotates, the signal detection set 5 on the first linkage block 2 can be carried by the first clutch block 31 to rotate in the same direction (of course, in other embodiments, the moving directions of the first handle 81 and the first linkage block 2 may also be different depending on the motion relationship therebetween). To sum up, 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 set 4 and the signal detection set 5 may be interchanged, that is, the first signal trigger set 4 is installed on the first linkage block 2, and the signal detection set 5 is installed on the fixed body 11. In any case, the first signal triggering group 4 and the signal detection group 5 cannot be mounted on the same member at the same time.

As shown in fig. 1, when the first handle 81 is in the home 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. The left non-detection area 51 is an area between the detection area of the middle signal detector 5b and the detection area of the left signal detector 5c, and the right non-detection area 52 is an area between the detection area of the middle signal detector 5b and the detection area of the right signal detector 5a, and when 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, 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. As shown in fig. 3, when the first handle 81 is pressed and rotated in the forward direction, the middle signal detector 5B moves towards the right to generate a signal B triggered by the right signal trigger 42, the left signal detector 5C moves towards the right to generate a signal C triggered by the left signal trigger 41, and the signal detection set 5 generates a BC signal set column composed of the signals B and C. Of course, in other embodiments, the first handle 81 can be further rotated toward the forward direction for some other special purpose, so that the left signal detector 5C passes over the left signal trigger 41 and then moves toward the right to generate the signal C triggered by the right signal trigger 42. As shown in fig. 4, when the first handle 81 is lifted to rotate in the reverse direction, the right signal detector 5a moves towards the left and is triggered by the right signal trigger 42 to generate a signal a, the middle signal detector 5B moves towards the left and is triggered by the left signal trigger 41 to generate a signal B, and the signal detection set 5 generates an AB signal set column composed of the signal a and the signal B. Of course, in other embodiments, the first handle 81 may continue to rotate in the reverse direction for some other special purpose, so that the right signal detector 5a continues to move toward the left after passing over the left signal trigger 42 to be triggered by the left signal trigger 41 to generate the signal a.

As shown in fig. 9, when the first handle 81 is at the home 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 a distance that the signal trigger needs to move relative to the signal detector in order to trigger the signal detector. In other embodiments, L1 may not be equivalent to L3, and L2 may not be equivalent to L4, e.g., L1 is smaller than L3 and L2 is smaller than L4. Thus, when the first handle 81 is pressed to rotate in the forward direction, the left signal trigger 41 triggers the left signal detector 5C to move to the right to generate the signal C, the right signal trigger 42 remains in the right non-detection area 52, and the middle signal detector 5B needs to move further to be triggered by the right signal trigger 42 to generate the signal B. The control unit takes a relatively long time to receive a complete BC signal train, and the control unit is also liable to misidentify the BC signal train as two single signals, signal B and signal C, thereby misjudging the steering of the handlebar. Accordingly, in the present embodiment, L1 corresponds to L3, and L2 corresponds to L4. In this way, the left signal trigger 41 triggers the left signal detector 5c, and the time duration of the movement stroke of the right signal trigger 42 triggering the middle signal detector 5b is equivalent, and similarly, the left signal trigger 41 triggers the middle signal detector 5b, and the time duration of the movement stroke of the right signal trigger 42 triggering the right signal detector 5a is equivalent. The control unit does not need to extend the receiving time for receiving the complete signal array, so that the power consumption of the control unit is reduced, and in addition, the control unit is not easy to wrongly identify the composition signals in the signal array as two single signals to cause misjudgment, so that the accuracy of identifying the movement direction of the first handle 81 is improved.

Further, the width W1 of the left non-detection area 51 is equivalent to the width W2 of the right non-detection area 52, and when the first handle 81 is at the home position, the left signal trigger 41 is located at the width-direction center position of the left non-detection area 51, and the right signal trigger 42 is located at the width-direction center position of the right non-detection area 52. According to the above technical solution, the left signal trigger 41 is equivalent to the moving stroke and the time duration of the middle signal detector 5b and the left signal detector 5c, respectively, and is also equivalent to the right signal trigger 42 which is equivalent to the moving stroke and the time duration of the middle signal detector 5b and the right signal detector 5a, respectively. The intelligent lock is suitable for the intelligent lock with the equivalent forward or reverse movement stroke of the first handle 81. The following describes an exemplary switching relationship between the moving direction of the first handle and the locked and unlocked states of the intelligent lock with reference to fig. 1, fig. 2, fig. 4, fig. 7 and table 1.

As shown in fig. 1, the clutch pin 33 is in an ejected state, and at this time, the clutch 3 is in a disengaged state, that is, the first clutch block 31 and the second clutch block 32 are in a disengaged state, and the intelligent lock is in a locked state. If the first handle 81 is pressed down to rotate in the forward direction as shown in fig. 3, when the left signal trigger 41 triggers the left signal detector 5C to form a signal C, the right signal trigger 42 can trigger the middle signal detector 5B to form a signal B at substantially the same time, and the control unit can receive the signals C and B at substantially the same time and accurately distinguish the first handle 81 as rotating in the forward direction according to the BC signal group sequence formed by the signals C and B. At this time, the driver 7 responds to the clutch signal sent by the control unit to keep the original state and not act, the clutch pin 33 keeps the pop-up state, the clutch 3 keeps the separation state, at this time, the first handle 81 is pressed down to be incapable of controlling the telescopic movement of the lock tongue 91, and the intelligent lock is kept in the locked state. If the first handle 81 is lifted up to rotate in the reverse direction as shown in fig. 4, the control unit can accurately recognize that the first handle 81 rotates in the reverse direction by receiving the AB signal series consisting of the signals a and B at substantially the same time. At this time, the driver 7 responds to the clutch signal sent by the control unit to control the clutch pin 33 to pop out and hold, and since the clutch pin 33 pops out at this time, the clutch pin 33 will keep a popped out state to keep the clutch 3 in a separated state, the first handle 81 is pressed down to be incapable of controlling the telescopic movement of the lock tongue 91, and the intelligent lock keeps a locked state.

As shown in fig. 2, the clutch pin 33 is in an inserted state, and the clutch 3 is in an engaged state, that is, the first clutch block 31 and the second clutch block 32 are in an engaged state, and the intelligent lock is in an unlocked state. If the first handle 81 is pressed down to rotate in the forward direction as shown in fig. 7, the control unit receives the BC signal array, at this time, the driver 7 responds to the clutch signal sent by the control unit to keep the original state and not to act, the clutch pin 33 keeps the insertion state, the clutch 3 keeps the engaged state, the first handle 81 is pressed down to control the telescopic movement of the lock tongue 91, and the intelligent lock keeps the normally open state. If the first handle 81 is lifted up to rotate reversely as shown in fig. 8, the control unit receives the AB signal array, and 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 insertion state and maintain the ejection state, so that the clutch 3 is switched to the separation state, and the intelligent lock is switched from the normally open state to the locked state. In other embodiments, the control unit can also control other components to operate after identifying the moving direction of the first handle 81 according to the signal array transmitted by the three signal detectors, for example, control a warning light to flash to give a prompt signal, etc.

According to the technical scheme, compared with the prior art, the invention has the beneficial technical effects that: due to the spatial layout relationship between the first signal trigger group 4 and the signal detection group 5, when the first handle 81 rotates in the forward direction or in the reverse direction, the middle signal detector 5B can cooperate with one of the left signal detector 5C and the right signal detector 5a to generate two signal group columns containing different information, namely a signal a and a signal B or a signal B and a signal C, respectively, so as to distinguish the rotation direction of the first handle 81 and then determine the next operation. Secondly, both of the signal group columns are generated using the intermediate signal detector 5b, providing a utilization of the intermediate signal detector 5 b. Thirdly, the signal array contains at least two kinds of signal information, and the signal array has obvious difference from a single signal with only one kind of signal information and is strong in distinguishability. Therefore, the position of other moving components or the moving direction of other moving components can be distinguished by generating a single signal in a mode that the middle signal detector 5b, the left signal detector 5c and the right signal detector 5a independently complete the detection work, and the single signal is not mixed with the signal array formed when the first handle 81 rotates forwards or backwards, namely, the moving state of other moving components can be detected on the basis of not increasing the signal detectors, the utilization rate of the original three signal detectors is greatly improved, and the expansibility of the handle direction-distinguishing detection system is optimized.

The structure for discriminating the moving direction of the second handle 82 will be further described below. In this embodiment, the second signal trigger 6 is located in the left non-detection area 51 when the first handle 81 and the second handle 82 are in the original positions. As shown in fig. 1, the clutch pin 33 is in the ejected state, and the clutch 3 is in the disengaged state. If the second handle 82 is pressed downwards to rotate in the forward direction relative to the first handle 81 as shown in fig. 5, the second linkage block 321 carries the second signal trigger 6 to move towards the right, and the intermediate signal detector 5B is triggered by the second signal trigger 6 to generate a signal B. If the second handle 82 is lifted up to rotate in the opposite direction with respect to the first handle 81 as shown in fig. 6, the second linkage block 321 carries the second signal trigger 6 to move to the left, and the left signal detector 5C is triggered by the second signal trigger 6 to generate the signal C. The signals B and C are single signals, and can be used to distinguish the moving direction of the second handle 82 and the signal train formed when the first handle 81 moves. When the control unit receives a single signal it identifies the second handle 82 moving instead of the first handle 81 and identifies the direction of movement of the second handle 82 based on whether signal B or signal C is received.

As shown in fig. 9, when the first handle 81 and the second handle 82 are in the original positions, 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, the trigger stroke between the second signal trigger 6 and the middle signal detector 5b is L6, wherein L5 corresponds to L1, and L6 corresponds to L2. As shown in fig. 2, the clutch 3 is in a 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, so that the same signal detector is not triggered intermittently and successively, and thus signal confusion is caused. At this time, the control unit receives a signal array, and the information composition of the signal array formed when only the first handle 81 is moved is consistent, and no new type of signal is formed, which is advantageous to simplify the setting of the logic determination program in the control unit.

Further, the width W1 of the left non-detection area 51 corresponds to the width W2 of the right non-detection area 52, and when the first handle 81 and the second handle 82 are at the home positions, the second signal trigger 6 is located at the center in the width direction of the left non-detection area 51. In this way, the second signal trigger 6 respectively triggers the moving strokes of the middle signal detector 5b and the left signal detector 5c, and the time duration is equivalent, so that the intelligent lock with the equivalent forward or reverse moving stroke of the second handle 82 is suitable for use. (in other embodiments, when the first and second handles 81 and 82 are in the home position, the second signal trigger 6 is located in the right non-detection area 52, the trigger stroke between the second signal trigger 6 and the middle signal detector 5b is L7, the trigger stroke between the second signal trigger 6 and the right signal detector 5a is L8, where L7 corresponds to L3 and L8 corresponds to L4; and the further second signal trigger 6 is located at the center position in the width direction of the right non-detection area 52).

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 kept on the same reference geometric line, the reference geometric line is a circular line (in other embodiments, the reference geometric line may also be a straight line), and a center of the reference geometric line coincides with the point O. Wherein 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 the same spatial layer, the second signal trigger 6 is located on the third spatial layer, and the three spatial layers are arranged above and below each other, so that motion interference when the first signal trigger group 4, the signal detection group 5 and the second signal trigger 6 move is avoided. The vertical direction is a direction perpendicular to the door. The above "remaining on the same reference geometric line" means that the motion trajectories and the positions of the first signal trigger group 4, the signal detection group 5 and the second signal trigger 6 at rest are all located on the reference geometric line.

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