The intelligent door lock is a composite lock which is improved on the basis of being different from the traditional mechanical lock and is more intelligent and simplified in the aspects of user safety, identification and manageability.

The intelligent door lock in the related art comprises a lock body, a motor and an optical coupler device, wherein a driving gear of the motor is used for driving a lock tongue on the lock body to extend and retract, so that the functions of locking and unlocking are realized. In order to detect whether the driving gear rotates in place, a baffle is arranged on the driving gear of the motor, after the driving gear starts to rotate, when the baffle is outside the optocoupler, the optocoupler outputs a low level, and after the motor rotates to return to a position, the baffle rotates to the inside of the optocoupler to block the optocoupler, and the optocoupler outputs a high level, so that whether the motor rotates to a specified position can be judged through the high level and the low level. However, the current intelligent door lock has some problems in use. For example, the specific rotation position of the motor in the automatic lock body or the extension/retraction position of the lock tongue cannot be accurately determined, and meanwhile, whether the motor rotates in place or not cannot be accurately determined in the rotation process, so that unnecessary trouble is brought to people.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Because the motor rotation that present intelligent lock exists detects inaccurately, the motor stall appears easily and the excessive problem of motor rotation, in order to solve this problem, have put forward in the relevant technique and detect the motor rotation state through the detection scheme of high low level.

However, the detection scheme of the high and low levels can only detect two states of motor rotation in place and motor rotation out of place, and cannot accurately judge the specific position of the motor in the rotation process. In addition, when the motor rotates in place due to inertia, the controller can mistakenly consider that the motor is not in place due to the low level output by the optical coupler, the motor can continue to rotate until the motor drives the lock body to rotate to trigger rotation, and if the motor rotates in place, the motor can be further caused to rotate, so that the motor reciprocates, and the lock body can continuously extend and retract. In addition, when the motor is blocked by the lock body or other mechanical parts, the traditional detection mode cannot judge at all, and the current of the motor reaches a peak value during the blocking, so that the loss of power consumption is brought on one hand, and the service life of the motor of the lock body can be influenced to a certain extent for a long time. Therefore, the above high-low level detection scheme cannot detect the motor rotation over-position and motor stalling.

Referring to fig. 1, in order to solve the above problems, an embodiment of a lock 1000 is provided, wherein the lock 1000 includes a housing 1100, a lock body structure 100 (200) accommodated in the housing 1100, and a controller 1200, and the lock body structure 100 (200) is electrically connected to the controller 1200.

Referring to fig. 2 and 3, the lock body structure 100 includes: the lock tongue 1, the motor 2, a detection gear 4 arranged on the output shaft of the motor 2, and a detection mechanism 3 positioned on one side of the detection gear away from the output shaft of the motor 2. The bolt 1 comprises a bolt body 11 and a bolt gear 12 arranged on the bolt body 11, and a driving gear 21 of the motor 2 is meshed with the bolt gear 12 to drive the bolt 1 to extend or retract. The detection gear 4 includes a body 41, the body 41 is a circular body, and a first baffle group 42 and a second baffle group 43 are circumferentially spaced apart from the body 41. The first baffle group 42 includes oppositely disposed first and second ends 422, 423 and the second baffle group 43 includes oppositely disposed third and fourth ends 432, 433. Wherein the first end 422 of the first baffle group 42 is disposed adjacent to the third end 432 of the second baffle group 43, and a first spacing region 44 is formed between the first end 422 and the third end 432; the second end 423 of the first baffle group 42 is disposed adjacent to the fourth end 433 of the second baffle group 43 with a second spacer 45 formed therebetween. The second spacing region 45 has a circumferential arc length along the body portion 41 that is greater than the circumferential arc length of the first spacing region 44 along the body portion 41. The first barrier group 42 includes a plurality of first barriers 421 disposed along the circumferential direction of the body portion 41 and a third spacing region 424 between adjacent two of the first barriers 421. Wherein, when the detecting gear 4 rotates, the at least one first baffle 421 is used for triggering the detecting mechanism 3 to output a first level signal, and the first interval area 44, the second interval area 45 or the at least one third interval area 424 is used for triggering the detecting mechanism 3 to output a second level signal. The signal values of the first level signal and the second level signal may be the same or different, and in some embodiments, the first level signal may be a high level, and the second level signal may be a low level.

Referring to fig. 2 and 3 again, the second baffle group 43 includes a plurality of second baffles 431 disposed along the circumferential direction of the body portion 41 and a fourth spacing area 434 between two adjacent second baffles 431. At least one second baffle 431 is used for triggering the detection mechanism 3 to output the first level signal when the detection gear 4 rotates, and at least one fourth interval 434 is used for triggering the detection mechanism 3 to output the second level signal.

When the motor 2 rotates, the lock tongue gear 12 is driven to rotate and the detection gear 4 is driven to rotate in the same direction, so that the detection mechanism 3 can be triggered by a plurality of first baffles 421 or a plurality of second baffles 431 on the detection gear 4, the detection mechanism 3 is conducted to generate a first level signal, the first level signal can be a high level signal at the moment, and the controller 1200 can read the high level signal; when the detecting gear 4 rotates to rotate the first interval 44, the second interval 45, the third interval 424 or the fourth interval 434 to the position of the detecting mechanism 3, the detecting mechanism 3 is turned off, and the detecting mechanism 3 can generate the second level signal, and the second level signal may be the low level signal, and the controller 1200 reads the low level signal, so that the high level and the low level form the pulse signal. The accurate detection of the motion state of the motor 2 can be realized by detecting the number of pulse signals, pulse width, level overturning conditions and the like. For example, the specific position of the rotation of the motor 2 (or the specific position of the advance of the lock tongue 1) can be calculated according to the counting of the pulse signals, the test of the pulse width and the level overturning condition, so as to judge whether the lock tongue 1 is in place or not; whether the motor rotation is out of position or not can be judged through the overturning condition of the level in the pulse signal; in addition, a specific time may be set in advance, and if the level does not flip during this time, it may be determined that the motor 2 is locked, so that the motor 2 may be controlled to stop.

In some embodiments, each first baffle 421 of the plurality of first baffles 421 has a different dimension along the circumferential arc length of the body portion 41, and each second baffle 431 of the plurality of second baffles 431 has a different dimension along the circumferential arc length of the body portion 41. Along the circumferential direction of the body portion 41, the sizes of the plurality of first baffles 421 in the first baffle group 42 decrease or increase in sequence from the direction from the first end 422 to the second end 423, and the sizes of the plurality of second baffles 431 in the second baffle group 43 decrease or increase in sequence from the direction from the third end 432 to the fourth end 433. Since the plurality of first baffles 421 or the plurality of second baffles 431 are different in size along the circumferential arc length of the body portion 41, the plurality of first level signals formed are different in pulse width, and by setting the widths of the first baffles 421 and the second baffles 431 to be regularly increased or decreased, whether the motor 2 is rotating forward or backward, the specific position of the motor 2 movement, and the like can be further accurately determined by the regular increased or decreased variation of the pulse width, and the accuracy and convenience of detecting the movement state of the motor 2 can be further increased.

In some embodiments, the first baffle group 42 and the second baffle group 43 are disposed axisymmetrically on the body portion 41. The plurality of first baffles 421 in the first baffle group 42 sequentially increases in size from the first end 422 to the second end 423, and the plurality of second baffles 431 in the second baffle group 43 sequentially increases in size from the third end 432 to the fourth end 433, along the circumferential direction of the body portion 41. By symmetrically arranging the first barrier group 42 and the second barrier group 43, when the opening directions (left inside-out, left outside-in, right inside-out, and right outside-in) of the door are different, the generated pulse signals are the same, the judgment conditions are the same, and the complexity of the judgment of the motion state of the motor 2 is reduced. It is understood that the number of the first baffle 421 and the second baffle 431 may be two, three, or more, and may be set according to practical situations. In some embodiments, the number of the first baffles 421 and the second baffles 431 is three, the sizes of the three first baffles 421 along the circumferential arc length of the body portion 41 decrease sequentially from the first end 422 to the second end 423, and the sizes of the three second baffles 431 along the circumferential arc length of the body portion 41 decrease sequentially from the third end 432 to the fourth end 433.

The third plurality of spaced apart regions 424 may be the same or different in size and the fourth plurality of spaced apart regions 434 may be the same or different in size along the circumferential direction of the body portion 41. In some embodiments, the plurality of third spacer regions 424 are the same size and the plurality of fourth spacer regions 434 are the same size. The third spacers 424 and the fourth spacers 434 are set to have the same size, so that the pulse width sizes of the second level signals (low level) corresponding to the third spacers 424 or the fourth spacers 434 can be the same, and the judgment process only needs to pay attention to the first level signals (high level) with different pulse width sizes, so that the judgment process can be simplified, and the specific rotation positions of the motor 2 can be conveniently distinguished.

In some embodiments, the size of the first spaced regions 44 is smaller than the size of the second spaced regions 45 along the circumference of the body portion 41, i.e., the circumferential arc length of the second spaced regions 45 along the body portion 41 is greater than the circumferential arc length of the first spaced regions 44 along the body portion 41. This facilitates distinguishing the initial rotational position (or the position where the motor 2 rotates in place) from the position where the tongue 1 extends/retracts in place, and in addition, the first spacer 44 is relatively small in size, that is, the distance between the first end 422 of the first baffle group 42 and the third end 432 of the second baffle group 43 and the second end 422 of the second baffle group 43 is smaller than the distance between the second end 423 and the fourth end 433, at this time, if the motor 2 rotates in place, the rotating stroke of the motor 2 is short, which is beneficial to reducing the influence of the rotating in place on the performance of the motor 2.

The detection mechanism 3 is used for cooperating with the detection gear 4 to generate a pulse circuit, for example, the detection mechanism 3 can be a micro switch or a photoelectric sensor. In some embodiments, the detecting mechanism 3 is a micro switch, which is disposed outside the detecting gear 4. The micro switch includes a switch 31, when the detecting gear 4 rotates, the switch 31 is pressed when each first baffle 421 or each second baffle 431 rotates right above the switch 31, so that the micro switch outputs a first level signal, and when the first interval region 44, the second interval region 45, and each third interval region 424 or each fourth interval region 434 rotate right above the switch 31, the switch 31 is turned off, and the micro switch outputs a second level signal.

It will be appreciated that in other embodiments, the detection mechanism 3 may also be a photoelectric sensor (not shown) that includes a transmitting end and a receiving end that are disposed opposite to each other. When the detection gear 4 rotates, each first baffle 421 or each second baffle 431 rotates between the transmitting end and the receiving end, signals between the transmitting end and the receiving end are shielded, and at the moment, the photoelectric sensor outputs a first level signal; when the first spacer 44, the second spacer 45, and each third spacer 424 or each fourth spacer 434 are rotated between the transmitting end and the receiving end, the receiving end can receive the signal transmitted from the transmitting end, and at this time, the photosensor outputs a second level signal.

The lock 1000 adopting the lock body structure 100 only rotates 180 ° during the switching of the door opening and closing state, that is, only one of the first baffle group 42 and the second baffle group 43 in the detection gear 4 belongs to the effective working state, and the other does not participate in the switching process of the door opening and closing state, but does not participate in the judging process of whether the motor 2 rotates or not, according to the difference of the opening directions (left inside opening, left outside opening, right inside opening and right outside opening) of the door mounted by the lock 1000, of the first baffle 421 or the second baffle 431 close to the first partition area 44 in the one group of baffles of the effective working turntable.

Referring to fig. 1 to 3, the lock 1000 is used for opening/closing a door: when the first shutter 421 and the second shutter 431 press the switch 31 of the detection mechanism 3 with the rotation of the main body 41, the detection circuit of the detection mechanism 3 is turned on, and a first level signal (may be a high level) is generated; when the first spacer 44, the second spacer 45, the third spacer 424 or the fourth spacer 434 is located directly above the switch key 31, the switch key 31 is turned off, and the detection circuit of the detection mechanism 3 is turned off, so as to generate a second level signal (which may be a low level). When the first spacer 44 is at the initial position of the door closing state of the lock 1000, that is, the door closing state of the lock 1000, the first spacer 44 is located right above the switch key 31, the detection circuit is turned off, and the controller 1200 reads the second level signal (i.e., low level); the first end 422 of the first baffle group 42 or the third end 432 of the second baffle group 43 is located at an initial position right above the switch key 31, which is the open state of the lock 1000, that is, the switch key 31 is turned off when the first baffle group 42 or the second baffle group 43 is not abutting against the switch key 31 in the open state of the lock 1000, the detection circuit is turned off, and the second level signal (i.e., low level) is still read by the controller 1200.

The embodiments of the present application that employ the above lock body structure 100 to accurately detect the motion state of the motor 2 include the following cases. The first barrier group 42 is set to be in an effective operation state.

When the lock 1000 receives the door opening/closing command, the lock body structure 100 rotates, the controller 1200 reads the pulse signals of the detection mechanism 3, and records the pulse width and pulse count of the high level and the low level of each pulse signal between the initial state and the end state, so that the following motion states of the motor can be judged.

Case one: referring to fig. 1 to 3 in combination, the tongue 1 is extended/retracted whether or not in place: the initial position is that the first spacer 44 is located right above the switch key 31, and at this time, the switch key 31 is turned off, and the controller 1200 reads the second level signal (i.e. low level); the motor 2 starts to rotate, and a first baffle 421 positioned at a first end 422 in the first baffle group 42 firstly abuts against the switch key 31, so that the controller 1200 reads a first level signal (i.e. a high level); after the first baffle 421 passes, the first third spacer 424 is located right above the switch key 31, at this time, the switch key 31 is turned off, the controller 1200 reads the second level signal (i.e. low level), the motor 2 continues to rotate, and the other first baffles 421 and third spacer 424 of the first baffle group 42 sequentially pass through the switch key 31; when the motor 2 rotates to the position where the second spacing area 45 is located right above the switch key 31, the motor 2 rotates in place, and the lock tongue body 11 stretches out/retracts in place; when the bolt body 11 is extended/retracted to a proper position, the motor 2 cannot continue to rotate, and then starts to rotate in the opposite direction, at this time, the second end 423 of the first baffle group 42 starts to sequentially pass through the plurality of first baffles 421 and the third spacing areas 424 of the first baffle group 42 and rotate to the first spacing area 44, so that the motor 2 rotates to a proper position, and the motor 2 stops rotating.

In this process, since the three first baffles 421 in the first baffle group 42 have different arc lengths along the circumferential direction of the body portion 41, the first baffles 421 have different time for passing through the switch key 31, the pulse widths of the formed first level signals are different, and the formed pulse signals are as shown in fig. 4, and the specific rotation position of the motor 2 can be detected in real time according to the pulse count and the calculation of the pulse widths, so as to determine whether the motor 2 rotates in place or not, and whether the latch bolt body 11 extends/retracts in place or not.

And a second case: referring to fig. 1 to 3 in combination, whether the motor 2 is rotating too far or not: continuing the above-described rotation process, during the rotation of the motor 2, when the first spacer 44 is located directly above the switch lever 31, the controller 1200 reads the second level signal (i.e., low level), and then the controller 1200 reads the first level signal (i.e., high level), as shown in fig. 5, at this time, it may be determined that the motor 2 is rotated too far, because the second barrier 431 of the second barrier group 43, which is close to the first spacer 44, abuts against the switch lever 31, thereby generating the first level signal (i.e., high level). Therefore, whether the motor 2 rotates beyond the bit can be judged by judging whether the high level appears after the motor rotates beyond the bit in the pulse signal, and if the motor 2 rotates beyond the bit, the motor 2 is controlled to rotate back to the initial bit.

And a third case: referring to fig. 1 to 3 in combination, whether or not the motor 2 is locked: the motor 2 rotates in the process described in the first case, but when the controller 1200 reads that the pulse signal exceeds a certain time level and no overturn occurs, as shown in fig. 6, it can be determined that the motor 2 is blocked, so that the motor 2 can be controlled to stop rotating, so as not to cause loss to the motor 2.

In setting the predetermined time, the predetermined time may be set based on the time elapsed by the widest pulse width in the pulse signal, and the predetermined time may be set to be longer than the time elapsed by the widest pulse width, so that erroneous judgment can be avoided without causing the motor 2 to stall.

Referring to fig. 7 to 9, another embodiment of the present application provides a lock body structure 200, and the lock body structure 200 is mainly different from the lock body structure 100 provided in the previous embodiment in that: the blocking piece 4a of the lock body structure 200 is fixed on any tooth part of the driving gear 21 of the motor 2. The detection mechanism 10 of the lock body structure 200 includes a photosensor 5 and a grating sheet 6. The photoelectric sensor 5 includes a transmitting end 51 and a receiving end 52 which are disposed opposite to each other at a distance, the grating sheet 6 is located between the transmitting end 51 and the receiving end 52, and the blocking sheet 4a is located between the grating sheet 6 and the transmitting end 51 or between the grating sheet 6 and the receiving end 52. The grid plate 6 comprises a grid plate body 61, wherein the grid plate body 61 is an arc-shaped body, a plurality of through holes are formed in the grid plate body 61 along the circumferential direction of the grid plate body 61, and a spacing area is formed between two adjacent through holes. When the driving gear 21 drives the blocking piece 4a to rotate, the blocking piece 4a passes through at least one interval area and is used for triggering the receiving end 52 to receive the first optical signal emitted by the emitting end 51, so that the photoelectric sensor 5 outputs a first level signal; the blocking piece 4a is used for triggering the receiving end 52 to receive the second optical signal emitted by the emitting end 51 through at least one through hole, so that the photoelectric sensor 5 outputs a second level signal. The signal values of the first level signal and the second level signal may be the same or different.

Specifically, the through holes on the grid sheet body 61 are divided into a first through hole group 62 and a second through hole group 63, the through holes included in the first through hole group 62 are first through holes 621, the space between two adjacent first through holes 621 is a first space 624, the through holes included in the second through hole group 63 are second through holes 631, and the space between two adjacent second through holes 631 is a second space 634 along the circumferential direction of the grid sheet body 61 (i.e., the arc circumferential direction of the grid sheet body 61). The size of each of the plurality of first through holes 621 is different from each other along the circumferential direction of the grid piece body 61, and the size of each of the plurality of second through holes 631 is different from each other. When the driving gear 21 drives the blocking piece 4a to rotate, the blocking piece 4a passes through each first interval area 624 or each second interval area 634 to trigger the receiving end 52 to receive the first optical signal emitted by the emitting end 51, so that the photoelectric sensor 5 outputs a first level signal; the blocking piece 4a is used for triggering the receiving end 52 to receive the second optical signal emitted by the emitting end 51 through each first through hole 621 or each second through hole 631, so that the photoelectric sensor 5 outputs a second level signal, and the signal values of the first level signal and the second level signal are different.

When the motor 2 rotates, the latch bolt gear 12 is driven to rotate and simultaneously drives the baffle 4a to rotate, so that the baffle 4a passes through the grid plate 6, and the grid plate 6 is formed into a plurality of first through holes 621 with different sizes and a plurality of second through holes 631 with different sizes along the circumferential direction of the grid plate body 61. During the rotation of the driving gear 21, when the blocking piece 4a passes through the first interval area 624 or the second interval area 634, all the first through holes 621 and all the second through holes 631 can transmit light, the signals received by the receiving end 52 are the first optical signals, so that the photoelectric sensor 5 outputs the first level signals (may be relatively higher level signals), and when the blocking piece 4a rotates to the first through holes 621 or the second through holes 631 with different sizes, part of the first through holes 621 or the second through holes 631 can be blocked, so that the second optical signals received by the receiving end 52 are weakened relative to the first optical signals, so that the photoelectric sensor 5 outputs the second level signals (may be relatively lower level signals), and at the moment, the first level signals and the second level signals may be both high level signals, but by performing secondary processing on the first level signals and the second level signals, pulse signals with high level and low level can be formed. The accurate detection of the motion state of the motor 2 can be realized by detecting the number of pulse signals, pulse width, level overturning conditions and the like. For example, since the sizes of the plurality of first through holes 621 or the plurality of second through holes 631 are different, the time that the blocking piece 4a passes through the first through holes 621 or the second through holes 631 with different sizes is different, the pulse widths of the formed second level signals are different, and the specific rotation position (or the specific forward position) of the motor 2 can be calculated according to the counting of the pulse signals and the test of the pulse widths, thereby judging whether the latch bolt 1 is in place or not; whether the rotation of the motor 2 is out of position or not can be judged through the turnover condition of the level in the pulse signal; in addition, a specific time may be set in advance, and if the level does not flip during this time, it may be determined that the motor 2 is locked, so that the motor 2 may be controlled to stop.

In some embodiments, along the circumference of the grid plate body 61, the first through hole group 62 includes a first end 622 and a second end 623 disposed opposite to each other, the second through hole group 63 includes a third end 632 and a fourth end 633 disposed opposite to each other, the first end 622 and the third end 632 are disposed adjacent to each other with a third spacing area 64 formed therebetween, and the second end 623 and the fourth end 633 are spaced apart from each other. In some embodiments, the dimensions of the first through holes 621 decrease or increase in sequence from the first end 622 to the second end 623, and the dimensions of the second through holes 631 decrease or increase in sequence from the third end 632 to the fourth end 633, along the circumference of the grid slice body 61. By setting the sizes of the first through hole 621 and the second through hole 631 along the circumferential direction of the grid plate body 61 to be regularly increased or decreased, the time of the baffle 4a passing through the first through hole 621 or the second through hole 631 with different sizes can be regularly increased or decreased, so that the pulse width of the regular increase or decrease change can be converted, and whether the motor 2 rotates forward or backward, the specific position of the motor 2 motion and the like can be more accurately judged, so that the accuracy and convenience of detecting the motion state of the motor 2 can be further increased.

In some embodiments, the first through hole group 62 and the second through hole group 63 are disposed on the grid plate body 61 in an axisymmetric manner. By symmetrically arranging the first through-hole group 62 and the second through-hole group 63, when the opening directions (left inside-out, left outside-in, right inside-out, and right outside-in) of the door are different, the generated pulse signals are the same, the judgment conditions are the same, and the complexity of the judgment of the motion state of the motor 2 is reduced. It is understood that the number of the first through holes 621 and the second through holes 631 may be two or three, or more than three, which is set according to practical situations. In some embodiments, the first through hole group 62 includes three first through holes 621, and the sizes of the three first through holes 621 decrease in sequence from the first end 622 to the second end 623 along the circumferential direction of the grid plate body 61. The second through hole group 63 includes three second through holes 631, and the sizes of the three second through holes 631 decrease in sequence from the third end 632 to the fourth end 633 along the circumferential direction of the grid sheet body 61.

In some embodiments, the plurality of first spacers 624 are the same size and the plurality of second spacers 634 are the same size along the circumference of the grid plate body 61. By setting the plurality of first spacing regions 624 to have the same size and the plurality of second spacing regions 634 to have the same size, the variation in calculating the pulse width is reduced, which is advantageous in simplifying the complexity of the pulse width calculation.

In some embodiments, the dimensions of third spacer region 64 are greater than the dimensions of first spacer region 624 and second spacer region 634, respectively, along the circumference of grid sheet body 61. The third spacer 64 may serve as a starting rotational position or a turning-in-place position of the motor 2, and the size of the third spacer 64 may be set to be different from the sizes of the first spacer 624 and the second spacer 634 in order to distinguish the starting position and the turning-in-place position of the motor 2 from the pulse signal.

In some embodiments, the shape of the grating sheet 6 is the same as the shape of the movement path of the shutter 4a, i.e. the curvature of the grating sheet 6 is the same as the curvature of the movement path of the shutter 4 a. By setting the radian of the grid sheet 6 to be the same as the radian of the moving path of the baffle sheet 4a, the baffle sheet 4a can not block the first through hole 621 when passing through the first spacing region 624 in the rotation process or can not block the second through hole 631 when passing through the second spacing region 634, and likewise, the baffle sheet 4a can not block the first spacing region 624 when passing through the first through hole 621 in the rotation process or can not block the second spacing region 634 when passing through the second through hole 631, so that the matching accuracy of the baffle sheet 4a and the grid sheet 6 is improved, and the accuracy of judging the moving state of the motor 2 is further improved.

Referring to fig. 10, referring to fig. 7 to 9 in combination, the first through hole set 62 is set to be in an active working state, and the lock 1000 is in an opening/closing process: at the initial position, the blocking piece 4a is located in the third interval area 64, as shown in fig. 10 (a), and the receiving end 52 receives the first optical signal (the strongest optical signal), and at this time, the controller 1200 reads the first level signal (which may be a relatively high level signal); when the motor 2 rotates counterclockwise, the blocking piece 4a blocks a part of the first through holes 621 in the first through hole group 62, and the receiving end 52 receives the second optical signal of the transmitting end 51, at this time, since the blocking piece 4a blocks a part of the light, the second optical signal is weakened compared with the first optical signal, and the controller 1200 reads the second level signal (may be a relatively lower level signal); after the baffle 4a passes through the first through hole 621, the baffle 4a enters the first interval zone 624, and at this time, the receiving end 52 receives the first optical signal (the strongest optical signal), the controller 1200 reads the first level signal (the relatively higher level signal), the motor 2 continues to rotate, and the baffle 4a passes through the other first through holes 621 and the first interval zone 624 of the first through hole group 62 in sequence; when the motor 2 rotates to the area behind the second end 623 of the first through hole group 62, as shown in (b) of fig. 10, the receiving end 52 receives the first light signal (the strongest light signal) again, and the controller 1200 reads the first level signal (the relatively higher level signal) again, and at this time, the motor 2 rotates in place, and the latch main body 11 is extended/retracted in place; when the latch bolt body 11 is extended/retracted in place, the motor 2 cannot continue to rotate, and then starts to rotate in the opposite direction, at this time, the blocking piece 4a sequentially passes through the first through holes 621 and the first spacing areas 624 of the first through hole group 62 from the second end 623 of the first through hole group 62, and rotates to the third spacing area 64, as shown in fig. 10 (c) and (d), the motor 2 rotates in place, and the motor 2 stops rotating, and finally forms a pulse signal composed of the first level signal and the second level signal.

In this process, since the three first through holes 621 in the first through hole group 62 have different sizes along the circumferential direction of the grid plate body 61, the pulse widths of the first level signal and the second level signal formed are different, and since the first level signal and the second level signal are high levels with different absolute values, the pulse signals with high and low levels are obtained through secondary processing in a conventional signal processing manner, and then the specific rotation position of the motor 2 can be detected in real time according to the pulse count and the calculation of the pulse width, thereby judging whether the motor 2 rotates in place or not, and whether the bolt body 11 stretches out/retracts in place or not. In addition, whether the rotation of the motor 2 is out of place or not can also be judged according to the irregular overturn condition of the level overturn in the pulse signal, as shown in a (e) diagram in fig. 10; in addition, a specific time may be set in advance, and if the level does not flip during this time, it may be determined that the motor 2 is locked, so that the motor 2 may be controlled to stop.

The lock 1000 adopting the lock body structure 200 rotates only 90 ° during the switching of the door opening and closing state, that is, only one of the first through hole group 62 and the second through hole group 63 in the grating sheet 6 belongs to the effective working state, and the other group does not participate in the switching process of the door opening and closing state, but the first through hole 621 or the second through hole 631, which is close to the third partition area 64, of the group of through holes in the effective working state participate in the judging process of detecting whether the motor 2 rotates beyond according to the opening direction (left inward opening, left outward opening, right inward opening and right outward opening) of the door mounted by the lock 1000.

It should be noted that the above is only a specific embodiment of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily think about changes or substitutions within the technical scope of the present application, and the changes or substitutions should be covered in the scope of the present application; in the case of no conflict, the embodiments of the present application and features of the embodiments may be combined with one another. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
