In order to solve the technical problem the utility model provides a position measurement mechanism, tool to lock and device that opens and shuts. The opening and closing device comprises an opening and closing structure and a lockset. Wherein, the tool to lock is used for locking structure that opens and shuts. Wherein, the opening and closing structure can be a door and window structure or a folding structure. The lockset can realize the locking of the window body, the door body and the adjacent folding pieces. The opening and closing device in this embodiment will be described below with a door and window structure as an application scenario.
Referring to fig. 1 and 2, the lock includes a housing 10, a latch bolt 20, and a position determining mechanism 30. The position measuring mechanism 30 includes a trigger 31, a detecting unit 32, and a counting unit. As shown in fig. 2 and 3, the trigger 31 is movable relative to the detection assembly 32. The trigger 31 includes a first trigger part 311 and a second trigger part 312. The first trigger part 311 and the second trigger part 312 are adjacent along a moving path along which the trigger 31 moves relative to the detection member 32. The detection assembly 32 includes a first detection unit 321 and a second detection unit 322, and the first detection unit 321 is capable of forming a first detection position a on the trigger 31. Specifically, when the first detection position a moves to correspond to the first trigger part 311, the first detection unit 321 can generate the first signal. When the first detection position a moves to correspond to the second trigger 312, the first detection unit 321 can generate a second signal. That is, the first detecting unit 321 can generate different signals when the first detecting position a is in the first triggering part 311 and the second triggering part 312 respectively. Further, the second detecting unit 322 can form a second detecting position b on the trigger 31. The second detecting unit 322 can generate a third signal when the second detecting position b moves to correspond to the first triggering part 311, and the second detecting unit 322 can generate a fourth signal when the second detecting position b moves to correspond to the second triggering part 312. That is, the second detecting unit 322 can generate different signals when the second detecting position b is in the first triggering part 311 and the second triggering part 312, respectively. Further, when the trigger 31 moves relative to the detecting component 32, the first detecting unit 321 can complete a signal switching when the first detecting position a passes between the first trigger 311 and the second trigger 312, and the second detecting unit 322 can complete a signal switching when the second detecting position b passes between the first trigger 311 and the second trigger 312. The counting unit is used for recording the signal switching times of the first detection unit 321 and the second detection unit 322.
The above-mentioned manner of recording the number of signal switching times of the first detecting unit 321 and the second detecting unit 322 by the counting unit is easy to implement, and there are many means in the prior art, which are not described herein too much.
In this embodiment, the opening and closing structure includes an opening and closing member and a fixing member. Wherein the opening and closing piece is a window or a door body. The fixing piece is a window frame or a door frame. The lock case 10 is installed in the opening and closing member. As shown in fig. 1 and 2, the locking bolt 20 can move relative to the lock case 10 to protrude from or retract into the lock case 10, so as to drive one of the trigger 31 and the detection assembly 32 to move relative to the other. In particular, the opening and closing member can be moved towards the fixing member to reach the locking position. At this time, the latch bolt 20 protruding from the housing 10 may contract into the housing 10 after touching the fixing element, the latch bolt 20 may protrude from the housing 10 and be accommodated in the recess when facing the recess of the fixing element for accommodating the latch bolt 20, and the latch bolt 20 may drive one of the trigger 31 and the detection assembly 32 to move relative to the other in the process of contracting into the housing 10 and protruding out of the housing 10.
To sum up, implement the embodiment of the utility model provides a, will have following beneficial effect: the position measuring mechanism 30 of the above scheme is applied to be equipped in a lock and an opening and closing device, and can improve the detection precision of the position of the lock tongue 20 by itself so as to enable the lock to correctly judge the state of the lock tongue 20 besides ensuring that the lock and the opening and closing device have excellent locking efficiency. Specifically, the position measuring mechanism 30 includes a trigger 31 having a first trigger part 311 and a second trigger part 312, a detection unit 32 having a first detection unit 321 and a second detection unit 322, and a counting unit. The first trigger part 311 and the second trigger part 312 are adjacent to each other along a moving path of the trigger 31 moving relative to the detecting assembly 32. This enables the first detection position a and the second detection position b to generate a signal switching once when passing between the first trigger 311 and the second trigger 312, and determines the direction in which the trigger 31 moves relative to the detection assembly 32 according to the detection unit of the first detection unit 321 and the second detection unit 322 that preferentially generates the signal switching. Because the relative position between the first trigger part 311 and the second trigger part 312 is fixed and the relative position between the first detection unit 321 and the second detection unit 322 is fixed, the relative position between the trigger 31 and the detection assembly 32 can be determined according to the number of times of signal switching between the first detection unit 321 and the second detection unit 322, and then the position of the bolt 20 connected with one of the trigger 31 and the detection assembly 32 can be determined, so as to ensure that the lock can correctly determine the state of the bolt 20.
In one embodiment, as shown in fig. 3, the number of the first triggering parts 311 is multiple, and a plurality of the first triggering parts 311 are arranged at intervals along the moving path to form the second triggering parts 312 between the adjacent first triggering parts 311. Therefore, the adjacent positions of the first trigger part 311 and the second trigger part 312 can be formed, and further, in the process of one stroke of the trigger 31 moving relative to the detection assembly 32, the first detection unit 321 and the second detection unit 322 complete signal switching for multiple times, and the accuracy of measuring the relative position between the trigger 31 and the detection assembly 32 can be further improved according to the relative positions of the trigger 31 and the detection assembly 32 corresponding to different switching times, and the correctness of judging the state of the lock tongue 20 by the lock is improved.
In one embodiment, with continued reference to fig. 3, the dimensions L of the first trigger portion 311 and the second trigger portion 312 along the moving path are the same. The distance of the trigger 31 moving relative to the detection assembly 32 can be accurately measured through the product of the switching times and the size L, so that the measured moving precision is smaller than the size L, and the precision of the relative position between the trigger 31 and the detection assembly 32 is further improved.
In one embodiment, with continued reference to fig. 3, the distance between the first detection position a and the second detection position b along the moving path direction is (n + 0.5) L, where n is a natural number. Thus, when the trigger 31 moves 0.5L along the moving path relative to the detecting assembly 32, one of the first detecting unit 321 and the second detecting unit 322 generates signal switching, and the measured position accuracy is reduced to 0.5L. The detection precision is improved, and meanwhile, the size L is prevented from being too small, so that the machining precision and the process requirements of the trigger 31 are reduced. Further, since the trigger 31 moves 0.5L along the moving path relative to the detecting unit 32, it is only necessary to generate signal switching in one of the first detecting unit 321 and the second detecting unit 322, and therefore, the direction in which the trigger 31 moves relative to the detecting unit 32 can be determined according to the detecting unit that preferentially generates signal switching in the first detecting unit 321 and the second detecting unit 322, and the detection accuracy of the moving direction can be reduced to 0.5L while the position accuracy is reduced to 0.5L.
In one embodiment, the movement path has at least a calibration position. When the trigger 31 moves to the calibration position, the counting unit can be controlled to count and clear, so as to avoid counting errors due to environmental factors during long-time operation.
Further, the moving path also has a first position and a second position at the starting and ending points of the moving path. When the trigger 31 moves from the first position to the second position or from the second position to the first position, at least one of the positions on the moving path corresponding to the first detection unit 321 and the second detection unit 322 that complete the signal switching twice first (that is, the position on the moving path corresponding to the first detection unit 321 and the second detection unit 322 that complete the signal switching twice first) and the position on the moving path corresponding to the last complete the signal switching is the calibration position. Therefore, the calibration position is set at the initial stage of the movement of the trigger 31 relative to the detection component 32 to perform zero clearing operation on the counting unit, so that the accuracy of subsequent counting is ensured; or a calibration position is set at the end stage of the movement of the trigger 31 relative to the detection assembly 32, so as to perform zero clearing operation on the counting unit, and play a role in prompting in place, so as to prompt the relative position of the trigger 31 and the detection assembly 32 to reach a preset position, and meanwhile, the counting unit can conveniently count the number of times of signal switching first completed in the first detection unit 321 and the second detection unit 322 in the next stroke.
In one embodiment, one of the first trigger portion 311 and the second trigger portion 312 is a virtual structure such as a through hole or a through slot, and the other is a solid structure. As shown in fig. 3, in the present embodiment, the first trigger portion 311 is a solid structure. The second trigger portion 312 is a dummy structure. The first detection positions a are respectively located in the solid structure and the dummy structure, so that the first detection unit 321 can generate different signals. Similarly, the second detection positions b are respectively located in the solid structure and the virtual structure, so that the second detection unit 322 can generate different signals. As shown in fig. 3 and 4, in the present embodiment, the first detection unit 321 and the second detection unit 322 are photosensors. The first detection unit 321 includes a first transmitting end and a first receiving end. The trigger 31 is disposed between a first emitting end and a first receiving end, and the emitting light emitted from the first emitting end can form a first detecting position a on the trigger 31. The first trigger part 311 can block the emitted light from the first emitting end to prevent the first receiving end from receiving the emitted light, and at this time, the first detecting unit 321 can generate the first signal. The emitting light from the first emitting end can be received by the first receiving end through the second triggering portion 312, and at this time, the first detecting unit 321 can generate the second signal. Further, the second detection unit 322 includes a second transmitting end and a second receiving end. The trigger 31 is disposed between the second emitting end and the second receiving end, and the emitting light emitted from the second emitting end can form a second detecting position b on the trigger 31. The second trigger portion 312 can block the emitted light from the second emitting end to prevent the second receiving end from receiving the emitted light, and at this time, the second detecting unit 322 can generate the third signal. The emitting light from the second emitting end can be received by the second receiving end through the second triggering portion 312, and at this time, the second detecting unit 322 can generate a fourth signal.
It is understood that in other embodiments, the first trigger part 311 and the second trigger part 312 may be both solid structures, and may have different light transmittances, so that the first detection unit 321 and the second detection unit 322 generate different signals. In addition, the first triggering portion 311 and the second triggering portion 312 may have different light reflection properties, and at this time, the first emitting end and the first receiving end are located on the same side of the triggering member 31, and the first receiving end can receive the reflected light emitted by the first emitting end and reflected by the first triggering portion 311 and the second triggering portion 312. Similarly, at this time, the second emitting end and the second receiving end are also located on the same side of the triggering member 31, and the second receiving end can receive the reflected light emitted by the second emitting end and reflected by the first triggering portion 311 and the second triggering portion 312.
Further, as shown in fig. 3, the first triggering portion 311 and the second triggering portion 312 are arranged along a straight line, that is, the moving path is linear, and the direction of the moving path is parallel to the direction indicated by the arrow X in fig. 3. It is understood that in other embodiments, the first trigger part 311 and the second trigger part 312 may also be distributed along an arc, i.e. the moving path is a circular arc.
Fig. 4 is a schematic diagram of signal switching between the first detecting unit 321 and the second detecting unit 322 in this embodiment, that is, during a reciprocating process of the locking bolt 20, the signal switching between the first detecting unit 321 and the second detecting unit 322 is performed, wherein,
P 0 : the bolt 20 is completely pressed into the lock case 10, and the first detecting unit 321 is at the leftmost position of the trigger 31, i.e. the trigger 31 is at the first positionA location;
P 1 : the calibration position when the locking bolt 20 starts to eject in the process of ejecting the locking bolt 20;
P 2 : a calibration position when deadbolt 20 is fully ejected during the ejection of deadbolt 20;
P 3 : the bolt 20 is completely ejected, and the first detection unit 321 is at the rightmost position of the trigger 31, that is, the trigger 31 is at the second position;
P 4 : calibration position when locking bolt 20 starts to be pressed in during the pressing-in process of locking bolt 20;
P 5 : the calibration position when locking bolt 20 is completely pressed in during the pressing-in process of locking bolt 20;
P 6 : the bolt 20 is completely pressed into the lock case 10, and the first detecting unit 321 is at the leftmost position of the trigger 31, that is, the trigger 31 is at the first position;
t 0 : the time from full depression to full ejection of locking bolt 20;
t 1 : bolt 20 is fully ejected to the time of fully pressing in.
The counting unit can acquire the signal switching condition from the first detection unit 321 and the second detection unit 322, and is at P 1 ，P 2 ，P 4 ，P 5 And carrying out zero clearing operation at four positions.
By judging the relative phase of the signals of the first detection unit 321 and the second detection unit 322, the action direction of the bolt 20 is determined: when the phase of the first detecting unit 321 relative to the second detecting unit 322 is >0 (i.e. the signal switching of the second detecting unit 322 lags behind the first detecting unit 321), it is determined that the tongue 20 is in the pop-up state; when the phase of the first detecting unit 321 with respect to the second detecting unit 322 is <0 (i.e., the signal switching of the first detecting unit 321 lags behind the second detecting unit 322), it is determined that the latch bolt 20 is in the push-in state.
In one embodiment, as shown in fig. 1, a trigger 31 is provided to the locking bolt 20. The detection assembly 32 is arranged on the lock shell 10. Since the detection assembly 32 needs to be powered and wired for signal transmission in some embodiments, the detection assembly 32 is fixed in the lock case 10, so that the subsequent arrangement of wires can be facilitated, and the situation that the movement of the detection assembly 32 causes disconnection with the wires or winding of the wires, which affects the movement of the subsequent detection assembly 32, can be avoided.
In one embodiment, the lock further comprises a control unit and a functional component, wherein the control unit can control the functional component to be opened according to the signal switching times recorded by the counting unit. The functional component can be a main bolt, an alarm component or a monitoring unit and the like. The following describes how the control unit controls the main bolt by taking the functional unit as the main bolt as an example. The control unit can judge the moving direction and the moving position of the bolt 20 according to the signal switching times so as to judge the state of the bolt 20, and when the bolt 20 is judged to complete a complete reciprocating motion and completely protrude out of the lock shell 10, the control unit can control the main bolt to extend out to lock the opening and closing element and the fixing element. In some cases, the engaging member is closed due to different user operations or different opening and closing structures, but the locking tongue 20 does not fully extend, and at this time, the signal switching times can be recorded, so that the control unit controls the main locking tongue to extend to lock the engaging member and the fixing member when the signal switching times are subsequently reached. In this embodiment, the control unit can also control the counting unit to count and clear when the trigger 31 moves to the calibration position.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention, therefore, all equivalent variations of the present invention are intended to be covered by the present invention.
