Description

Technical Field

[0001] The present invention belongs to the technical field of locks, and specifically relates to a combination lock and a control method thereof. Background Art

[0002] In today's market of household door locks, the combination of a deadlock and a latch lock dominates. The design concept of this combination lock is to enhance the security of the door through a dual locking mechanism, providing a more reliable protection for the home living environment. However, in the actual daily use process, this seemingly secure combination brings a lot of inconvenience to users, seriously affecting the convenience of opening the door and the user experience.

[0003] When a user needs to open the door and go out, they must go through a series of complex and cumbersome operation processes. First, the user needs to use a knob, a handle or a key to perform a separate unlocking operation on the deadlock. This step seems simple, but actually requires a high degree of operation precision from the user. In actual scenarios, due to factors such as the rotation angle of the knob, the pressing force of the handle or the insertion depth of the key, the unlocking may fail. For example, the knob needs to be rotated precisely to a specific angle to trigger the unlocking mechanism. If the user rotates the angle insufficiently or excessively, the unlocking cannot be successful; when pressing the handle, if the force is insufficient, the internal lock tongue may not retract, and if the force is too large, the handle or the lock body may be damaged; when inserting the key, if it does not fully fit the tooth pattern of the lock core, the key cannot be turned. Once the operation is improper, the user needs to try repeatedly, which not only wastes time but also may make the user feel anxious and irritable when in a hurry to go out.

[0004] After unlocking the deadlock, the user cannot directly open the door and still needs to separately rotate the handle of the latch lock to unlock the latch lock. The entire door-opening process involves multiple operations, with complex steps and long time consumption. For modern people with a fast-paced daily life and precious time, this door-opening method is obviously not convenient enough. Especially when the user needs to go out quickly, the existing combination lock door-opening method greatly affects the user's travel efficiency and reduces the user experience. Moreover, in some emergency situations, such as fires, earthquakes and other disasters, this complex door-opening method may delay the escape time and pose a potential threat to the user's life safety. In addition, frequent complex operations are likely to cause the user to have a fidgety mood and affect the daily life mood.

[0005] Therefore, the existing combination lock that combines a deadlock and a latch lock has obvious deficiencies in terms of the convenience of opening the door, and there is an urgent need for a new door lock technology that can simplify the door-opening operation and improve the door-opening efficiency to solve the above problems.

It should also be understood that terms such as those defined in a general dictionary should be understood to have a meaning consistent with the meaning in the context of the prior art, and will not be interpreted with an idealized or overly formal meaning unless specifically defined as here.

[0079] The present invention provides a combination lock. When a user unlocks a latch bolt lock, the user can automatically and synchronously unlock a deadbolt lock by touching a touch module on the latch bolt lock of the combination lock, so that the user does not need to unlock the deadbolt lock and the latch bolt lock separately in sequence, thereby improving the unlocking efficiency of the combination lock and enhancing the user experience.

[0080] In an exemplary embodiment of the present invention, Figure 1 and Figure 2 ,or Figure 3 The combination lock 300 includes a control unit 310, a deadbolt lock 100 and a latch bolt lock 200, wherein the deadbolt lock 100 and the latch bolt lock 200 are separately arranged. The combination lock 300 is installed on a door body 400, and the door body 400 is installed on a door frame. The door frame is provided with two bolt grooves, which are a first bolt groove and a second bolt groove, respectively. The first bolt groove is arranged corresponding to the deadbolt lock 100, and the second bolt groove is arranged corresponding to the latch bolt lock 200.

[0081] The deadbolt lock 100 includes a motor 115, a transmission mechanism (the transmission mechanism is referred to as a first transmission mechanism) and a lock tongue (the lock tongue is referred to as a first lock tongue 160), the motor 115, the first transmission mechanism and the first lock tongue 160 are sequentially transmission-connected, the motor 115 drives the first lock tongue 160 to extend into the first lock tongue groove via the first transmission mechanism to achieve locking of the deadbolt lock 100, or the motor 115 drives the first lock tongue 160 to withdraw from the first lock tongue groove via the first transmission mechanism to achieve unlocking of the deadbolt lock 100. The control unit 310 is used to control the operation of the motor 115.

[0082] The oblique bolt lock 200 includes a handle 210, a touch module 220, a transmission mechanism (the transmission mechanism is referred to as a second transmission mechanism) and a lock tongue (the lock tongue is referred to as a second lock tongue 230), the handle 210, the second transmission mechanism and the second lock tongue 230 are sequentially connected in transmission, the handle 210 drives the second lock tongue 230 to extend into the second lock tongue groove through the second transmission mechanism to achieve locking of the oblique bolt lock 200, or the handle 210 drives the second lock tongue 230 to withdraw from the second lock tongue groove through the second transmission mechanism to achieve unlocking of the oblique bolt lock 200. The touch module 220 is electrically connected to the control unit 310.

[0083] Specifically, combined Figure 1 , Figure 3 and Figure 4, the second transmission mechanism includes a transmission shaft 240, one end of the transmission shaft 240 is inserted on the handle 210, the transmission shaft 240 is connected to the second locking tongue 230, and the second locking tongue 230 is disposed substantially perpendicular to the transmission shaft 240. When the handle 210 is rotated, the handle 210 drives the transmission shaft 240 to rotate simultaneously, and the transmission shaft 240 drives the second locking tongue 230 to move linearly relative to the second locking tongue groove, so that the second locking tongue 230 extends into or withdraws from the second locking tongue groove, thereby locking or unlocking the inclined tongue lock 200.

[0084] The touch module 220 is disposed on the handle 210, and the touch module 220 is electrically connected to the control unit 310. The touch module 220 includes a touch control 221 and a detection unit 222. The detection unit 222 is disposed within the handle 210, and the touch control 221 is disposed on the side surface of the handle 210 so that the touch control 221 is exposed on the handle 210.

[0085] Combined with Figure 2 , when the user locks or unlocks the combination lock 300, the user's hand holds the handle 210, and the user's hand touches the touch control 221 exposed on the handle 210. The detection unit 222 responds to the touch event of the touch control 221 and generates a target electrical signal. The detection unit 222 outputs the target electrical signal to the control unit 310. The control unit 310 generates a drive control signal based on the target electrical signal. The control unit 310 outputs the drive control signal to the motor 115 of the dead lock 100 to control the operation of the motor 115, thereby controlling the movement of the first locking tongue 160 through the motor 115, so that the dead lock 100 is unlocked or locked.

[0086] Thus, when the user rotates the handle 210 to unlock the inclined tongue lock 200, the user touches the touch module 220, and the touch module 220 generates a corresponding target electrical signal. The control unit 310 generates a drive control signal based on the received target electrical signal. The control unit 310 controls the operation of the motor 115 through the drive control signal to drive the first locking tongue 160 to operate through the motor 115, so as to unlock the dead lock 100. It can be understood that when the user rotates the handle 210 to unlock the inclined tongue lock 200, the dead lock 100 is also unlocked synchronously, so that the user can unlock in one step without separately unlocking the dead lock 100 and the inclined tongue lock 200, thereby reducing the unlocking steps of the combination lock 300, improving the unlocking efficiency, and enhancing the user experience.

[0087] In one embodiment, combined with Figure 1 and Figure 2 orFigure 3 The touch control module 220 is a switch module, the touch control member 221 of the touch control module 220 is a push switch, and the detection unit 222 is a switch circuit. When a user holds the handle 210, the user can press the push switch to cause the switch circuit to generate a corresponding target electrical signal. In this embodiment, when it is necessary to unlock the combination lock 300, the user holds the handle 210 and presses the push switch to correspondingly control the deadbolt lock 100 to unlock, and the user synchronously rotates the handle 210 to cause the latch lock 200 to unlock synchronously, so that the deadbolt lock 100 and the latch lock 200 of the combination lock 300 are unlocked synchronously, improving the unlocking efficiency and the user experience.

[0088] In another embodiment, the touch control module 220 is a fingerprint verification module, the touch control member 221 of the touch control module 220 is a fingerprint acquisition component, and the detection unit 222 is a fingerprint verification unit. When a user holds the handle 210, one of the user's fingers touches the fingerprint acquisition component, and the fingerprint acquisition component generates an electrical signal in response to the user operation event. The electrical signal carries user characteristic data, and the user characteristic data includes the user's fingerprint data. The fingerprint acquisition component outputs the acquired electrical signal to the fingerprint verification unit.

[0089] After receiving the electrical signal output by the fingerprint acquisition component, the fingerprint verification unit analyzes the corresponding user characteristic data from the electrical signal. An identity database containing the user characteristic data of legal users is preset in the fingerprint verification unit. The fingerprint verification unit compares the user characteristic data with each user characteristic data in the identity database. When the acquired user characteristic data matches one of the user characteristic data in the identity database, the fingerprint verification unit sets the corresponding electrical signal as the target electrical signal; otherwise, when the acquired user characteristic data does not match one of the user characteristic data in the identity database, the fingerprint verification unit sets the corresponding electrical signal as an invalid electrical signal. The fingerprint verification unit outputs the acquired target electrical signal to the control unit 310, and the control unit 310 controls the deadbolt lock 100 to be unlocked or locked based on the target electrical signal.

[0090] In this embodiment, when unlocking the combination lock 300, the user holds the handle 210, and one finger touches the fingerprint acquisition component. The fingerprint acquisition component generates an electrical signal, and the fingerprint verification unit determines whether it is a target electrical signal based on the electrical signal. If so, the target electrical signal is output to the control unit 310. The control unit 310 controls the deadbolt lock 100 to be unlocked, and the user simultaneously rotates the handle 210 so that the latch lock 200 is unlocked synchronously, thereby enabling the deadbolt lock 100 and the latch lock 200 of the combination lock 300 to be unlocked synchronously, improving the unlocking efficiency and enhancing the user experience.

[0091] In one embodiment, in combination with Figure 3 and Figure 4 , the handle 210 includes a vertical rod 211 and a horizontal rod 212. The vertical rod 211 is connected to the horizontal rod 212, and the vertical rod 211 and the horizontal rod 212 are disposed substantially perpendicular to each other. One end of the transmission shaft 240 is inserted into the vertical rod 211. The touch control 221 of the touch module 220 is disposed on the horizontal rod 212, and the touch control 221 is exposed on the horizontal rod 212. Since the user mainly holds the horizontal rod 212 when holding the handle 210, and the touch control 221 is disposed on the horizontal rod 212, it is more convenient for the user to touch the touch control 221, enhancing the user experience.

[0092] In this embodiment, the door body 400 includes a front surface 420 and a back surface 410. The horizontal rod 212 faces the back surface 410 of the door body 400, and the horizontal rod 212 is disposed close to the back surface 410. Two side surfaces are provided on the horizontal rod 212, and the two side surfaces are disposed substantially parallel to the door body 400. One side surface (referred to as the inner side surface, not shown) is disposed opposite to the back surface 410, and the other side surface (referred to as the outer side surface 2121) has the same orientation as the back surface 410, and the outer side surface 2121 is farther from the back surface 410 than the inner side surface. The touch control 221 is exposed on the outer side surface 2121, so that the user can observe the outer side surface 2121. In addition, the touch control 221 disposed on the outer side surface 2121 also conforms to ergonomics and is convenient for the user to touch the touch control 221 when holding the handle 210.

[0093] In a further embodiment, the touch control 221 is exposed on the outer side surface 2121 and is disposed close to the vertical rod 211 to further facilitate the user to touch the touch control 221 when holding the handle 210.

[0094] In a typical embodiment of the present invention, in combination with Figure 1 and Figure 2 , or, Figure 3 and Figure 4The control unit 310 is installed in the deadbolt lock 100. Since the deadbolt lock 100 and the latch bolt lock 200 are separately provided, the control unit 310 provided in the deadbolt lock 100 and the touch module 220 provided in the latch bolt lock 200 are connected by wire or wirelessly.

[0095] In one embodiment, in combination Figure 1 and Figure 2 , the control unit 310 is wirelessly connected to the touch module 220. Specifically, the deadbolt lock 100 is further provided with a first communication unit 170, and the first communication unit 170 is electrically connected to the control unit 310; the latch bolt lock 200 is provided with a second communication unit 250, and the second communication unit 250 is electrically connected to the touch module 220, and the first communication unit 170 and the second communication unit 250 are wirelessly connected. The control unit 310 and the touch module 220 realize data communication via the first communication unit 170 and the second communication unit 250. In this embodiment, it is recommended that both the first communication unit 170 and the second communication unit 250 are near field communication devices to realize good data communication in a short distance, for example, both the first communication unit 170 and the second communication unit 250 are radio frequency devices, but this should not be understood as a limitation to the present invention.

[0096] In another embodiment, in combination Figure 3 and Figure 4 , the control unit 310 is connected to the touch module 220 by wire. Specifically, the control unit 310 is connected to the touch module 220 by a cable 320, so that good data interaction is achieved between the control unit 310 and the touch module 220. In this embodiment, the cable 320 can be arranged in the door body 400 to prevent the cable 320 from being interfered by the external environment and extend the service life of the cable 320. In this embodiment, it is recommended that the cable 320 is an electronic harness, but it should not be understood as a limitation to the present invention.

[0097] In a typical embodiment of the present invention, the deadbolt 100 includes the first transmission mechanism and the first lock tongue 160, the first transmission mechanism includes the lock core paddle 150, one end of the lock core paddle 150 is connected to the lock core of the deadbolt 100, the lock core paddle 150 is connected to the first lock tongue 160, the lock core paddle 150 drives the first lock tongue 160 to move linearly along the extension direction of the first lock tongue 160, so that the first lock tongue 160 extends into the first lock tongue groove or withdraws from the first lock tongue groove to achieve locking or unlocking of the deadbolt 100.

[0098] The lock core paddle 150 is arranged perpendicular to the first locking tongue 160, and the lock core paddle 150 is fixedly arranged with the first locking tongue 160. In combination with Figure 7 , the lock core paddle 150 is of a flat columnar structure. The lock core paddle 150 includes an adjacent unlocking surface 151 and a locking surface 152. The unlocking surface 151 is perpendicular to the locking surface 152, and the width of the unlocking surface 151 is greater than the width of the locking surface 152. When the lock core paddle 150 is rotated so that the unlocking surface 151 of the lock core paddle 150 faces the first locking tongue groove, the first locking tongue 160 withdraws from the first locking tongue groove to achieve unlocking; when the lock core paddle 150 is rotated so that the locking surface 152 of the lock core paddle 150 faces the first locking tongue groove, the first locking tongue 160 extends into the first locking tongue groove to achieve locking.

[0099] In a typical embodiment of the present invention, in combination with Figure 8 , the first transmission mechanism further includes a rotating shaft 111, a gear disk 120, a linkage block 113, a photoelectric sensor 114, and the motor 115. The control unit 310 is electrically connected to the photoelectric sensor 114 and the motor 115 respectively, and the motor 115 is used to drive the gear disk 120 to rotate. In combination with Figure 6 , the rotating shaft 111 is connected to the lock core paddle 150. In combination with Figure 11 , the linkage block 113 is arranged on the rotating shaft 111. The gear disk 120 is provided with a gear hole, and the gear disk 120 is sleeved on the rotating shaft 111 through the gear hole. The gear hole is a circular hole, and the section of the rotating shaft 111 corresponding to the gear hole is a cylindrical structure, so that the gear hole is sleeved on the rotating shaft 111, and the gear disk 120 cannot directly drive the rotating shaft 111 to rotate. Or, the aperture of the gear hole is greater than the shaft diameter of the rotating shaft 111, so that there is no transmission fit between the gear hole and the rotating shaft 111, so that the gear disk 120 cannot directly drive the rotating shaft 111 to rotate.

[0100] In combination with Figure 9 and Figure 11, a transmission block 122 is provided on the toothed disc 120, and the transmission block 122 and the linkage block 113 on the rotating shaft 111 are arranged on the same rotation path. When the motor 115 drives the toothed disc 120 to rotate, the transmission block 122 provided on the toothed disc 120 will move synchronously. Since the transmission block 122 and the linkage block 113 are arranged on the same rotation path, the transmission block 122 will abut against the linkage block 113 during rotation, so that the transmission block 122 will drive the rotating shaft 111 to rotate through the linkage block 113. The rotating shaft 111 will drive the lock core dial 150 to rotate, and the lock core dial 150 will drive the first lock tongue 160 to move linearly, so that the first lock tongue 160 extends into or withdraws from the first lock tongue groove, so that the dead lock 100 is locked or unlocked.

[0101] Combined with Figure 9 and Figure 10 , a plurality of light shielding sheets 130 are provided on the toothed disc 120, and the toothed disc 120 will drive the light shielding sheets 130 to rotate synchronously. The photoelectric sensor 114 is arranged on the rotation path of the light shielding sheets 130. When the toothed disc 120 drives the light shielding sheet 130 to pass through the photoelectric sensor 114, the light shielding sheet 130 will block the light emitted by the photoelectric sensor 114, so that the photoelectric sensor 114 generates a light shielding signal. The photoelectric sensor 114 outputs the light shielding signal to the control unit 310, and the control unit 310 obtains the rotation angle of the toothed disc 120 based on the light shielding signal and judges the working state of the dead lock 100.

[0102] In this embodiment, a plurality of light shielding sheets 130 are provided on the toothed disc 120, and the plurality of light shielding sheets 130 are evenly arranged in the circumferential direction of the toothed disc 120. For example, if two light shielding sheets 130 are provided on the toothed disc 120, the two light shielding sheets 130 are arranged at 180°; if three light shielding sheets 130 are provided on the toothed disc 120, the three light shielding sheets 130 are arranged in sequence along the circumferential direction of the toothed disc 120, and the angle between adjacent two light shielding sheets 130 is 120°.

[0103] In this embodiment, the present invention is described by taking the example that four light shielding plates 130 are provided on the toothed disc 120, but this should not be understood as limiting the present invention. Specifically, the four light shielding plates 130 are arranged in sequence along the circumferential direction of the toothed disc 120, and the distance between two adjacent light shielding plates 130 is 90°. When the motor 115 drives the toothed disc 120 to rotate, the toothed disc 120 will drive the four light shielding plates 130 to rotate synchronously. Assuming that when the toothed disc 120 is not rotating, the angle at which the photoelectric sensor 114 is blocked by one of the light shielding plates 130 is 0°; when the motor 115 drives the toothed disc 120 to rotate, and the photoelectric sensor 114 is blocked by another light shielding plate 130, the control unit 310 receives the light shielding signal output by the photoelectric sensor 114, and the control unit 310 determines that the toothed disc 120 has rotated 90°.

[0104] The control unit 310 controls the forward and reverse rotation of the motor 115 and the rotation direction of the toothed disc 120 by outputting the driving control signal to the motor 115. The control unit 310 controls the rotation of the lock cylinder paddle 150 by controlling the rotation of the toothed disc 120, thereby controlling the first lock tongue 160 to extend into or exit the first lock tongue groove, and further controlling the locking or unlocking of the deadbolt 100. In addition, the control unit 310 monitors the rotation angle of the toothed disc 120 through the photoelectric sensor 114 to prevent the rotation angle of the toothed disc 120 from being too large or too small, so that the deadbolt 100 can be accurately locked or unlocked.

[0105] In this embodiment, combined with Figure 9 , the transmission block 122 is extended along the circumferential direction of the toothed disc 120, so that the two end faces 1221 of the transmission block 122 along the circumferential direction are set at an angle. The two end faces 1221 can be selected to abut against the linkage block 113 on the rotating shaft 111, so as to drive the rotating shaft 111 to rotate through the linkage block 113. Specifically, when the control unit 310 controls the motor 115 to rotate forward, one of the end faces 1221 abuts against the linkage block 113; when the control unit 310 controls the motor 115 to rotate reversely, the other end face 1221 abuts against the linkage block 113; thereby improving the rotation efficiency of the toothed disc 120. In the present invention, it is recommended that the transmission block 122 be set across 180°, that is, the two end faces 1221 are set at 180°, so that when the motor 115 rotates forward or reversely, the rotation angle of the transmission block 122 can be reduced so as to quickly abut against the linkage block 113.

[0106] In a typical embodiment of the present invention, a travel groove 121 is provided on the toothed disc 120, and the travel groove 121 is extended along the circumferential direction of the toothed disc 120, and the travel groove 121 and the transmission block 122 are extended along the same extension path, and the travel groove 121 and the transmission block 122 are connected end to end to form an annular structure. In addition, the two end surfaces 1221 of the transmission block 122 constitute the two groove walls of the travel groove 121 in the circumferential direction. In this embodiment, the present invention is described by taking the transmission block 122 as being arranged across 180° along the circumferential direction, and the travel groove 121 as being arranged across 180° along the circumferential direction, but it should not be understood as limiting the present invention.

[0107] Combination Figure 8 and Figure 11 The first transmission mechanism is further provided with a linkage ring 118, the linkage ring 118 is sleeved on the rotating shaft 111, and the linkage ring 118 and the rotating shaft 111 are fixedly arranged, and the linkage block 113 is fixedly arranged on the linkage ring 118. In other words, the linkage block 113 is fixedly arranged on the rotating shaft 111 via the linkage ring 118. In this embodiment, it is recommended that the linkage ring 118 and the linkage block 113 are integrally formed, but this is not to be understood as a limitation to the present invention.

[0108] Combination Figure 9 and Figure 11 The toothed disc 120 is provided with an annular groove 123, and the annular groove 123 is arranged on the inner side of the travel groove 121, that is, the annular groove 123 is closer to the gear hole of the toothed disc 120 than the travel groove 121. The annular groove 123 is connected with the travel groove 121, the linkage ring 118 is installed in the annular groove 123, and the linkage block 113 on the linkage ring 118 is inserted into the travel groove 121, so that the linkage block 113 is limited by the travel groove 121, and one of the two end surfaces 1221 of the transmission block 122 can be selectively abutted against the linkage block 113.

[0109] When the toothed disc 120 rotates, one of the end faces 1221 of the transmission block 122 abuts against the linkage block 113, and the toothed disc 120 further rotates to drive the linkage block 113 to rotate through the corresponding end face 1221, and the linkage block 113 in turn drives the rotating shaft 111 and the lock core paddle 150 to rotate, and then drives the first lock tongue 160 to move linearly, so that the first lock tongue 160 extends into or exits the first lock tongue groove, so as to achieve locking or unlocking of the deadbolt 100.

[0110] In order to facilitate the description of the working principle of the deadbolt 100 of the present invention, Figure 12 and Figure 13 , Figure 12Schematic plan view when the rotating shaft, linkage ring, and photoelectric sensor are assembled together Figure 13 Schematic plan view of the toothed disc 120. Assume that the four light-shielding plates 130 on the toothed disc 120 are, in sequence along the circumferential direction of the toothed disc 120, the first light-shielding plate 131, the second light-shielding plate 132, the third light-shielding plate 133, and the fourth light-shielding plate 134. Assume that the two end faces 1221 of the transmission block 122 are respectively the first end face 1222 and the second end face 1223.

[0111] Combined with Figure 14 , assume that the deadlock 100 is in the locked and reset state, the first light-shielding plate 131 is at the photoelectric sensor 114, the photoelectric sensor 114 generates a light-shielding signal, and the control unit 310 determines that the deadlock 100 is in the locked and reset state based on the light-shielding signal. Also, the first end face 1222 abuts against the linkage block 113 of the linkage ring 118.

[0112] Combined with Figure 14 and Figure 15 , when the deadlock 100 needs to be unlocked, the control unit 310 outputs the drive control signal to the motor 115, controls the motor 115 to rotate forward, the motor 115 drives the toothed disc 120 to rotate counterclockwise by 90°, and the first end face 1222 on the transmission block 122 drives the linkage ring 118 to rotate counterclockwise by 90° through the linkage block 113. Among them, the first light-shielding plate 131 on the toothed disc 120 will leave the photoelectric sensor 114, the photoelectric sensor 114 no longer generates a light-shielding signal but generates a photoelectric signal. After the control unit 310 receives the photoelectric signal, the control unit 310 determines that the first light-shielding plate 131 has left the photoelectric sensor 114. At the same time, the fourth light-shielding plate 134 on the toothed disc 120 will rotate counterclockwise by 90° to the photoelectric sensor 114, the fourth light-shielding plate 134 will block the light emitted by the photoelectric sensor 114, and a light-shielding signal is generated again. After the control unit 310 receives the light-shielding signal, it determines that the fourth light-shielding plate 134 has rotated to the photoelectric sensor 114 and determines that the deadlock 100 has been unlocked. Meanwhile, the first end face 1222 on the toothed disc 120 also drives the linkage ring 118, the rotating shaft 111, the lock core dial 150, and the first locking tongue 160 to rotate, so that the first locking tongue 160 retracts relative to the first locking tongue groove to complete the unlocking, and the deadlock 100 is in the unlocked state.

[0113] Combined with Figure 15 and Figure 16, after the deadbolt 100 is in the unlocked state, the control unit 310 controls the motor 115 to reverse. The motor 115 drives the gear disk 120 to rotate clockwise by 180°, so that the first end face 1222 of the transmission block 122 rotates clockwise by 180° to separate from the linkage block 113, and the second end face 1223 of the transmission block 122 synchronously rotates clockwise by 180° to abut against the linkage block 113. During the process of the gear disk 120 rotating clockwise by 180°, neither the first end face 1222 nor the second end face 1223 is linked with the linkage block 113, so that the gear disk 120 does not drive the linkage ring 118, the rotating shaft 111, the lock core shim 150 and the first locking tongue 160 to rotate through the linkage block 113. Moreover, during the process of the gear disk 120 rotating clockwise by 180°, the fourth light shielding piece 134 will leave the photoelectric sensor 114, so that the photoelectric sensor 114 generates a photoelectric signal, and the first light shielding piece 131 and the second light shielding piece 132 sequentially pass through the photoelectric sensor 114. The photoelectric sensor 114 generates a light shielding signal, a photoelectric signal and a light shielding signal based on the first light shielding piece 131 and the second light shielding piece 132 in sequence, and the second light shielding piece 132 stays at the photoelectric sensor 114. The control unit 310 sequentially receives the photoelectric signal and the light shielding signal output by the photoelectric sensor 114. Thus, the control unit 310 correspondingly determines that the deadbolt 100 is in the unlocked and reset state, preparing for locking the deadbolt 100 later.

[0114] Combined with Figure 16 and Figure 17, when the deadlock 100 is in the unlocked reset state and it is necessary to lock the deadlock 100, the control unit 310 outputs the drive control signal to the motor 115, controls the motor 115 to reverse, and the motor 115 drives the gear disk 120 to rotate clockwise by 90°, so that the second end face 1223 of the transmission block 122 drives the abutted linkage block 113 to rotate clockwise by 90°, and the linkage block 113 drives the linkage ring 118, the rotating shaft 111, the lock core dial 150 and the first locking tongue 160 to move synchronously, so that the first locking tongue 160 extends out relative to the first locking tongue groove and is inserted into the first locking tongue groove, thereby making the deadlock 100 in the locked state. Moreover, during the process of the gear disk 120 rotating clockwise by 90°, the second light shielding piece 132 will leave the photoelectric sensor 114, so that the photoelectric sensor 114 generates a photoelectric signal; then the third light shielding piece 133 will rotate clockwise by 90° to the photoelectric sensor 114, and the photoelectric sensor 114 correspondingly generates a light shielding signal, and the third light shielding piece 133 stays at the photoelectric sensor 114. The control unit 310 sequentially receives the photoelectric signal and the light shielding signal output by the photoelectric sensor 114. Thus, the control unit 310 correspondingly determines that the deadlock 100 is in the locked state.

[0115] Combined with Figure 17 and Figure 14, after the deadbolt 100 is in the locked state, the control unit 310 controls the motor 115 to rotate forward. The motor 115 drives the gear disk 120 to rotate counterclockwise by 180°, so that the second end face 1223 of the transmission block 122 rotates counterclockwise by 180° to separate from the linkage block 113, and the first end face 1222 of the transmission block 122 rotates counterclockwise by 180° synchronously to abut against the linkage block 113. During the rotation of the gear disk 120, neither the first end face 1222 nor the second end face 1223 is linked with the linkage block 113, so that the gear disk 120 does not drive the linkage ring 118, the rotating shaft 111, the lock core dial 150 and the first lock tongue 160 to rotate through the linkage block 113. Moreover, during the process of the gear disk 120 rotating counterclockwise by 180°, the third light blocking piece 133 will leave the photoelectric sensor 114, so that the photoelectric sensor 114 generates a photoelectric signal, and the second light blocking piece 132 and the first light blocking piece 131 pass through the photoelectric sensor 114 in sequence. The photoelectric sensor 114 generates a light blocking signal, a photoelectric signal and a light blocking signal based on the second light blocking piece 132 and the first light blocking piece 131 in sequence, and the first light blocking piece 131 stays at the photoelectric sensor 114. The control unit 310 receives the photoelectric signal and the light blocking signal output by the photoelectric sensor 114 in sequence. Thus, the control unit 310 correspondingly judges that the deadbolt 100 is in the locked and reset state, preparing for unlocking the deadbolt 100 later.

[0116] Thus, the above text describes the whole process of the deadbolt 100 of the present invention from the locked and reset state - the unlocked state - the unlocked and reset state - the locked state - the locked and reset state. The deadbolt 100 can judge the state of the deadbolt 100 through the received photoelectric signal and light blocking signal, so that the control unit 310 can accurately control the operation of the deadbolt 100 only through a single photoelectric sensor 114, reducing the number of sensors of the deadbolt 100 and lowering the production cost of the deadbolt 100.

[0117] In one embodiment, in combination with Figure 10 , Figure 11 and Figure 12 , a Hall sensor 141 and a magnet 142 are further arranged on the first transmission mechanism. The magnet 142 is arranged on the rotating shaft 111. When the rotating shaft 111 rotates, the rotating shaft 111 will drive the magnet 142 to rotate synchronously. The Hall sensor 141 is arranged on the rotation path of the magnet 142. When the magnet 142 approaches the Hall sensor 141, the Hall sensor 141 will generate a Hall signal.

[0118] In this embodiment, the Hall sensor 141 is disposed adjacent to the photoelectric sensor 114, and the Hall sensor 141 is disposed at a 90° angle with respect to the first locking tongue groove. The magnet 142 is disposed at a 90° angle with respect to the linkage block 113. Since the rotating shaft 111 and the lock core dial 150 are fixedly provided and the rotating shaft 111 and the lock core dial 150 rotate synchronously, the orientation of the magnet 142 and the orientation of the locking surface 152 of the lock core dial 150 are set to be the same.

[0119] Combined with Figure 14 and Figure 15 , when the control unit 310 controls the motor 115 to operate, the motor 115 drives the gear disk 120 to rotate, the gear disk 120 drives the rotating shaft 111 to rotate, so that the unlocking surface 151 of the rotating shaft 111 faces the first locking tongue groove, and the first locking tongue 160 withdraws from the first locking tongue groove, and the deadlock 100 is unlocked. At the same time, the locking surface 152 of the rotating shaft 111 faces the Hall sensor 141, the magnet 142 approaches the Hall sensor 141, the Hall sensor 141 senses the magnet 142, generates a first Hall signal, and when the control unit 310 receives the first Hall signal, it determines that the deadlock 100 is in an unlocked state.

[0120] Combined with Figure 16 and Figure 17 , when the control unit 310 controls the motor 115 to operate, the motor 115 drives the first locking tongue 160 through the gear disk 120, the rotating shaft 111 and the lock core dial 150, so that when the locking surface 152 of the first locking tongue 160 faces the first locking tongue groove, the first locking tongue 160 extends into the first locking tongue groove, and the deadlock 100 is locked. At the same time, the magnet 142 moves away from the Hall sensor 141, the Hall sensor 141 cannot sense the magnet 142, and thus the Hall sensor 141 generates a second Hall signal. When the control unit 310 receives the second Hall signal, it determines that the deadlock 100 is in a locked state.

[0121] Thus, the deadlock 100 of the present invention can use the Hall sensor 141 to assist in determining whether the deadlock 100 is in a locked state, a locked reset state, an unlocked state, and an unlocked reset state, so that the control unit 310 can accurately monitor the state of the deadlock 100.

[0122] In one embodiment, combined with Figure 5 , Figure 6 and Figure 8The deadbolt lock includes a housing 143 and a knob 144. The shaft 111, the toothed disc 120, the linkage ring 118, the photoelectric sensor 114, the Hall sensor 141, the motor 115 and the control unit 310 are all installed in the housing 143. The shaft 111 protrudes from the housing 143. The lock core paddle 150 is inserted into the end of the shaft 111 protruding from the housing 143, and the lock core paddle 150 is fixedly connected to the shaft 111. The knob 144 is pivotally mounted on the housing 143, and the knob 144 and the shaft 111 are arranged on both sides of the housing 143, and the other end of the shaft 111 is inserted into the knob 144, and the shaft 111 and the knob 144 are fixedly connected.

[0123] The user can rotate the knob 144 to drive the rotating shaft 111, the lock core paddle 150 and the first lock tongue 160 to rotate, so that the first lock tongue 160 extends or retracts relative to the first lock tongue groove, so that the deadbolt 100 is locked or unlocked. It can be understood that the deadbolt 100 can be locked or unlocked by physically rotating the knob 144. In this embodiment, it is recommended that the knob 144 and the rotating shaft 111 are integrally formed, but this should not be understood as a limitation to the present invention.

[0124] In a further embodiment, in combination Figure 5 , Figure 12 , Figures 14 to 17 , an indication mark line 145 is provided on the knob 144, and the direction of the indication mark line 145 is the same as the direction of the upper locking surface 152 of the lock core paddle 150, and the knob 144 is fixed to the rotating shaft 111. When the lock core paddle 150 rotates, the first lock tongue 160 extends into the first lock tongue groove, and the upper locking surface 152 faces the first lock tongue groove, the knob 144 also rotates synchronously with the rotating shaft 111, so that the indication mark line 145 also points to the first lock tongue groove, indicating that the deadbolt 100 is in a locked state. Conversely, when the lock core paddle 150 rotates, so that the upper locking surface 152 no longer faces the first lock tongue groove, the knob 144 rotates synchronously, so that the indication mark line no longer points to the first lock tongue groove, indicating that the deadbolt 100 is in an unlocked state.

[0125] In one embodiment, in combination Figure 8 and Figure 10 The deadbolt lock is further provided with a circuit board 146 , and the circuit board 146 is installed in the housing 143 . The photoelectric sensor 114 and the Hall sensor 141 are both integrated on the circuit board 146 .

[0126] The present invention also provides a combined lock control method, which is implemented based on the combined lock 300 described above, and the control unit 310 of the combined lock 300 is used to execute the combined lock control method, so that when the user holds the handle 210 of the deadbolt lock 200 and touches the touch module 220 on the handle 210, the control unit 310 can synchronously control the deadlock 100 to be unlocked, so that the deadbolt lock 200 and the deadlock 100 can be unlocked simultaneously, reducing the unlocking steps and improving the user experience. In a typical embodiment of the present invention, in combination with Figure 18 , the combined lock control method includes the following specific steps:

[0127] Step S1100, receiving a target electrical signal detected by the touch module of the deadbolt lock;

[0128] When the user needs to unlock or lock the lock, the user holds the handle 210 of the deadbolt lock 200, and the user touches the touch module 220 arranged on the handle 210. The touch module 220 correspondingly generates a target electrical signal, and the touch module 220 outputs the target electrical signal to the control unit 310.

[0129] Step S1200, in response to the target electrical signal, outputting a drive control signal to the motor of the deadlock to drive the motor to unlock or lock the lock tongue of the deadlock;

[0130] After receiving the target electrical signal, the control unit 310 obtains the current state of the deadlock 100. For example, the current deadlock 100 is in any one of the locked reset state, locked state, unlocked state, and unlocked reset state.

[0131] If the deadlock 100 is in the locked reset state, the control unit 310 correspondingly generates a drive control signal (referred to as the first drive control signal) based on the target electrical signal. The control unit 310 drives the motor 115 to rotate through the first drive control signal, drives the first transmission mechanism of the deadlock 100 to move through the motor 115, and drives the first lock tongue 160 of the deadlock 100 to withdraw from the first lock tongue groove through the first transmission mechanism, so that the deadlock 100 is unlocked. Moreover, the user holds the handle 210 of the deadbolt lock 200 at the same time and rotates the handle 210 to complete the unlocking of the deadbolt lock 200. Thus, when the user completes the unlocking of the deadbolt lock 200, the control unit 310 controls the deadlock 100 to be unlocked as well, so that the user does not need to unlock the deadlock 100 separately, reducing the unlocking steps and improving the user experience.

[0132] When the deadbolt 100 is in the unlocked and reset state, the control unit 310 generates a drive control signal (referred to as the second drive control signal) based on the target electrical signal. The control unit 310 drives the motor 115 to rotate through the second drive control signal, drives the first transmission mechanism of the deadbolt 100 through the motor 115, and drives the first locking tongue 160 of the deadbolt 100 to extend into the first locking tongue groove through the first transmission mechanism, so that the deadbolt 100 is locked. Thus, the user can control the deadbolt 100 to be locked only by touching the touch module 220 on the touch handle 210, so that the user does not need to perform a complex deadbolt 100 locking process, improving the user experience.

[0133] Based on any embodiment of the combined lock control method of the present invention, combined with Figure 14 、 Figure 15 and Figure 19 , in the step of outputting a drive control signal to the motor of the deadbolt to drive the motor to drive the locking tongue of the deadbolt to unlock, the following specific steps are included:

[0134] Step S1210, controlling the motor to drive the gear disk to rotate in the first direction, and the gear disk drives the lock core to rotate a first angle through the linkage ring, the lock core drives the locking tongue to unlock, the linkage ring is sleeved on the rotating shaft, the lock core is linked with the rotating shaft and the locking tongue respectively, the gear disk is provided with a travel groove, the travel groove is arranged across a preset angle along the rotation direction of the gear disk, and the linkage block fixed on the linkage ring is inserted into the travel groove;

[0135] When the deadbolt 100 is in the locked and reset state, after the control unit 310 receives the target electrical signal output by the touch module 220, the control unit 310 generates a first drive control signal based on the target electrical signal, and the control unit 310 outputs the first drive control signal to the motor 115 to control the motor 115 to work, so that the deadbolt 100 is unlocked.

[0136] Specifically, when the deadbolt 100 is in the locked and reset state, the first light blocking piece 131 is at the photoelectric sensor 114, the photoelectric sensor 114 generates a light blocking signal, the linkage block 113 of the linkage ring 118 is inserted into the travel groove 121, and the first end face 1222 of the transmission block 122 abuts against the linkage block 113.

[0137] When the control unit 310 generates the first drive control signal based on the target electrical signal, the control unit 310 controls the motor to work based on the first drive control signal. Specifically, the motor 115 is controlled to rotate forward, and the motor 115 drives the toothed disc 120 to rotate 90° counterclockwise (in the first direction), and the first end surface 1222 on the transmission block 122 drives the linkage ring 118 to rotate 90° counterclockwise via the linkage block 113.

[0138] Step S1220, receiving a light shielding signal output by the photoelectric sensor due to being shielded by a light shielding sheet, wherein the toothed disc is provided with a plurality of light shielding sheets, and the plurality of light shielding sheets are evenly arranged along the circumferential direction of the toothed disc;

[0139] The first light shielding sheet 131 on the toothed disc 120 will leave the photoelectric sensor 114, and the photoelectric sensor 114 will no longer generate a light shielding signal, but a photoelectric signal. After the control unit 310 receives the photoelectric signal, the control unit 310 determines that the first light shielding sheet 131 has left the photoelectric sensor 114. At the same time, the fourth light shielding sheet 134 on the toothed disc 120 will rotate 90° counterclockwise to the photoelectric sensor 114, and the fourth light shielding sheet 134 will shield the light emitted by the photoelectric sensor 114, and generate a light shielding signal again.

[0140] Step S1230, judging whether the deadlock is unlocked based on the light shielding signal;

[0141] The control unit 310 receives the photoelectric signal and the light shielding signal sequentially output by the photoelectric sensor, determines that the fourth light shielding sheet 134 rotates to the photoelectric sensor 114, and determines that the deadbolt 100 has completed unlocking. At the same time, the first end surface 1222 on the toothed disc 120 also drives the linkage ring 118, the rotating shaft 111, the lock core paddle 150 and the first lock tongue 160 to rotate, so that the first lock tongue 160 retreats relative to the first lock tongue groove to complete unlocking, so that the deadbolt 100 is in an unlocked state.

[0142] At the same time, the user also holds the handle 210 of the latch bolt lock 200 and turns the handle 210, so that the latch bolt lock 200 is also unlocked synchronously. It can be understood that after the user touches the control module 220 on the handle 210, the control unit 310 is instructed to control the deadbolt lock 100 to unlock. After that, the user turns the handle 210 to unlock the latch bolt lock 200, and the control unit 310 synchronously controls the deadbolt lock 100 to unlock, so that the latch bolt lock 200 and the deadbolt lock 100 of the combination lock 300 are unlocked synchronously, so that the user reduces the steps of unlocking the deadbolt lock 100, simplifies the unlocking steps of the combination lock 300, and improves the user's use experience.

[0143] Based on any embodiment of the combination lock control method of the present invention, combined with Figure 15 , Figure 16 and Figure 20 , after the step of determining that the deadlock is unlocked, the following steps are further included:

[0144] Step S1240, generate an unlocking reset instruction;

[0145] After the control unit 310 determines that the deadlock 100 is in the unlocked state, the control unit 310 generates an unlocking reset instruction. The control unit 310 controls the motor 115 to operate based on the unlocking reset instruction, and drives the first transmission mechanism through the motor 115, so that the deadlock 100 moves from the unlocked state to the unlocking reset state.

[0146] Step S1250, based on the unlocking reset instruction, the control unit drives the gear disk to rotate a second angle in the second direction, so that one of the groove walls of the travel groove abuts against the linkage block;

[0147] Based on the unlocking reset instruction, the control unit 310 controls the motor 115 to reverse, and the motor 115 drives the gear disk 120 to rotate 180° clockwise (the second direction), so that the first end face 1222 of the transmission block 122 rotates 180° clockwise to separate from the linkage block 113, and the second end face 1223 of the transmission block 122 rotates 180° clockwise synchronously to abut against the linkage block 113. During the process of the gear disk 120 rotating 180° clockwise, neither the first end face 1222 nor the second end face 1223 is linked with the linkage block 113, so that the gear disk 120 does not drive the linkage ring 118, the rotating shaft 111, the lock core dial 150 and the first lock tongue 160 to rotate through the linkage block 113.

[0148] Step S1260, receive at least two light-shielding signals sequentially output by the photoelectric sensor within the first predetermined time period;

[0149] The control unit 310 controls the rotation speed of the motor 115 based on the unlocking reset instruction, and correspondingly obtains the first predetermined duration required for the motor 115 to drive the gear disk 120 to rotate clockwise by 180°. Within the first predetermined duration, during the process of the gear disk 120 rotating clockwise by 180°, the fourth light blocking piece 134 will leave the photoelectric sensor 114, causing the photoelectric sensor 114 to generate a photoelectric signal, and the first light blocking piece 131 and the second light blocking piece 132 will sequentially pass by the photoelectric sensor 114. The photoelectric sensor 114 generates a light blocking signal, a photoelectric signal, and a light blocking signal based on the first light blocking piece 131 and the second light blocking piece 132 in sequence, and the second light blocking piece 132 stays at the photoelectric sensor 114.

[0150] Step S1270, based on the at least two light blocking signals, determine that the deadlock has completed unlocking and resetting;

[0151] The control unit 310 sequentially receives the light blocking signal, the photoelectric signal, and the light blocking signal output by the photoelectric sensor 114. Thus, the control unit correspondingly determines that the deadlock 100 is in the unlocking and resetting state, preparing for locking the deadlock 100 later.

[0152] On the basis of any embodiment of the combined lock control method of the present invention, in combination with Figure 14 、 Figure 15 and Figure 21 , in the step of receiving the light blocking signal output by the photoelectric sensor when blocked by the light blocking piece, the following steps in parallel are further included:

[0153] Step S1280, receive the first Hall signal output by the Hall sensor in response to the magnet, and the magnet is arranged on the rotating shaft;

[0154] During the process from the locked and reset state to the unlocked state, when the control unit 310 controls the motor 115 to operate, the motor 115 drives the gear disk 120 to rotate counterclockwise by 90°. The gear disk 120 drives the rotating shaft 111 to rotate, so that the unlocking surface 151 of the rotating shaft 111 faces the first lock tongue groove, and the first lock tongue 160 withdraws from the first lock tongue groove, and the deadlock 100 is unlocked. At the same time, the locking surface 152 of the rotating shaft 111 faces the Hall sensor 141, the magnet 142 approaches the Hall sensor 141, and the Hall sensor 141 senses the magnet 142 and generates a first Hall signal.

[0155] Step S1290, simultaneously based on the first Hall signal and the light blocking signal, determine that the deadlock has completed unlocking;

[0156] While receiving the light-shielding signal, the control unit 310 also receives the first Hall signal. The control unit 310 determines that the deadbolt 100 is in the unlocked state based on the light-shielding signal, and the control unit assists in determining that the deadbolt 100 is in the unlocked state through the first Hall signal to verify the accuracy of the deadbolt 100 being in the unlocked state.

[0157] Based on any embodiment of the combined lock control method of the present invention, in combination with Figure 15 、 Figure 16 and Figure 22 , in the step of receiving at least two light-shielding signals sequentially output by the photoelectric sensor within the first predetermined time period, it further includes the following parallel steps:

[0158] Step S1261, within the first predetermined time period, continuously receive the first Hall signal output by the Hall sensor;

[0159] During the process from the unlocked state to the unlocked and reset state, within the first predetermined time period, when the control unit 310 drives the gear disk 120 to rotate through the motor 115, since the transmission block 122 on the gear disk 120 does not abut against the linkage block 113 during rotation, the transmission block 122 will not drive the rotating shaft 111 to rotate through the linkage block 113, so that the Hall sensor 141 will continuously sense the magnet 142, and thus continuously generate the first Hall signal.

[0160] Step S1262, based on the first Hall signal and the at least two light-shielding signals, determine that the deadbolt has completed unlocking and resetting;

[0161] During the process from the unlocked state to the unlocked and reset state, the control unit 310 sequentially receives the light-shielding signal, the photoelectric signal, and the light-shielding signal output by the photoelectric sensor 114. At the same time, the control unit 310 also continuously receives the first Hall signal. The control unit 310 determines that the deadbolt 100 is in the unlocked and reset state based on the light-shielding signal, the photoelectric signal, and the light-shielding signal output by the photoelectric sensor 114, and the control unit 310 assists in determining that the deadbolt 100 is in the unlocked and reset state through the continuously received first Hall signal to verify the accuracy of the deadbolt 100 being in the unlocked and reset state.

[0162] Based on any embodiment of the combined lock control method of the present invention, in combination with Figure 16 、 Figure 17 and Figure 23 , in the step of outputting a drive control signal to the motor of the deadbolt to drive the motor to drive the bolt of the deadbolt to lock, it includes the following specific steps:

[0163] Step S1310, controlling the motor to drive the toothed disc to rotate in the second direction, and the toothed disc drives the lock core to rotate a third angle via the linkage ring, the lock core drives the lock tongue to unlock, the linkage ring is sleeved on the rotating shaft, the lock core is respectively linked with the rotating shaft and the lock tongue, a travel groove is provided on the toothed disc, the travel groove is arranged across a preset angle along the rotation direction of the toothed disc, and a linkage block fixed on the linkage ring is inserted into the travel groove;

[0164] When the deadbolt 100 is in an unlocking and resetting state, after the control unit 310 receives the target electrical signal output by the touch module 220, the control unit 310 generates a second driving control signal based on the target electrical signal, and the control unit 310 outputs the second driving control signal to the motor 115 to control the motor 115 to operate, so that the deadbolt 100 is unlocked.

[0165] Specifically, when the deadbolt 100 is in the unlocked reset state and the deadbolt 100 needs to be locked, the control unit 310 outputs the second drive control signal to the motor 115 to control the motor 115 to reverse, and the motor 115 drives the toothed disc 120 to rotate 90° clockwise, so that the second end face 1223 of the transmission block 122 drives the abutting linkage block 113 to rotate 90° clockwise, and the linkage block 113 drives the linkage ring 118, the rotating shaft 111, the lock core paddle 150 and the first lock tongue 160 to move synchronously, so that the first lock tongue 160 extends relative to the first lock tongue groove and is inserted into the first lock tongue groove, thereby making the deadbolt 100 in a locked state.

[0166] Step S1320, receiving a light shielding signal outputted by the photoelectric sensor due to being shielded by a light shielding sheet, wherein the toothed disc is provided with a plurality of light shielding sheets, and the plurality of light shielding sheets are evenly arranged along the circumferential direction of the toothed disc;

[0167] When the toothed disc 120 rotates 90° clockwise, the second light blocking plate 132 will leave the photoelectric sensor 114, causing the photoelectric sensor 114 to generate a photoelectric signal; then the third light blocking plate 133 will rotate 90° clockwise to the photoelectric sensor 114, and the photoelectric sensor 114 will generate a light shielding signal accordingly, and the third light blocking plate 133 will stay at the photoelectric sensor 114.

[0168] Step S1330, based on the light shielding signal, determining whether the deadlock is locked;

[0169] The control unit 310 receives the photoelectric signal and the light shielding signal output by the photoelectric sensor 114 in sequence, and accordingly, the control unit 310 determines that the deadbolt 100 is in a locked state.

[0170] Based on any embodiment of the combination lock control method of the present invention, combined with Figure 17 , Figure 14 and Figure 24 , after the step of determining that the deadlock is locked, the following steps are further included:

[0171] Step S1350, generating a locking reset instruction;

[0172] After the control unit 310 determines that the deadlock 100 is in the locked state, the control unit 310 generates a locking reset instruction. The control unit 310 controls the motor 115 to operate based on the locking reset instruction, and drives the first transmission mechanism through the motor 115, so that the deadlock 100 moves from the locked state to the locking reset state.

[0173] Step S1360, based on the locking reset instruction, controlling the motor to drive the gear disk to rotate a fourth angle in the first direction, so that one of the groove walls of the stroke groove abuts against the linkage block;

[0174] The control unit 310 controls the motor 115 to rotate forward based on the locking reset instruction. The motor 115 drives the gear disk 120 to rotate counterclockwise by 180°, so that the second end face 1223 of the transmission block 122 rotates counterclockwise by 180° to separate from the linkage block 113, and the first end face 1222 of the transmission block 122 rotates counterclockwise by 180° synchronously to abut against the linkage block 113. During the rotation of the gear disk 120, neither the first end face 1222 nor the second end face 1223 is linked with the linkage block 113, so that the gear disk 120 does not drive the linkage ring 118, the rotating shaft 111, the lock core dial 150, and the first lock tongue 160 to rotate through the linkage block 113.

[0175] Step S1370, receiving at least two light-shielding signals sequentially output by the photoelectric sensor within a second predetermined time period;

[0176] The control unit 310 controls the rotation speed of the motor 115 based on the unlocking reset instruction, and correspondingly obtains the second predetermined time period required for the motor 115 to drive the gear disk 120 to rotate counterclockwise by 180°. During the process of the gear disk 120 rotating counterclockwise by 180°, the third light-shielding piece 133 will leave the photoelectric sensor 114, so that the photoelectric sensor 114 generates a photoelectric signal, and the second light-shielding piece 132 and the first light-shielding piece 131 sequentially pass through the photoelectric sensor 114. The photoelectric sensor 114 generates a light-shielding signal, a photoelectric signal, and a light-shielding signal based on the second light-shielding piece 132 and the first light-shielding piece 131 in sequence, and the first light-shielding piece 131 stays at the photoelectric sensor 114.

[0177] Step S1380, based on the at least two shading signals, determining whether the deadlock has completed locking and resetting;

[0178] The control unit 310 receives the photoelectric signal and the light shielding signal output by the photoelectric sensor 114 in sequence, and accordingly, the control unit determines that the deadbolt 100 is in a locked reset state, and prepares for unlocking the deadbolt 100 later.

[0179] Based on any embodiment of the combination lock control method of the present invention, Figure 16 , Figure 17 and Figure 25 The step of receiving the light shielding signal output by the photoelectric sensor when the photoelectric sensor is blocked by the light shielding sheet also includes the following steps in parallel:

[0180] Step S1410, receiving a second Hall signal output by the Hall sensor when the Hall sensor does not respond to a magnet, wherein the magnet is disposed on the rotating shaft;

[0181] In the process from the unlocking and resetting state to the locking state, when the control unit 310 controls the motor 115 to work, the motor 115 drives the first lock tongue 160 through the toothed disc 120, the rotating shaft 111 and the lock core paddle 150, so that when the upper locking surface 152 of the first lock tongue 160 faces the first lock tongue groove, the first lock tongue 160 extends into the first lock tongue groove, and the deadbolt 100 is locked. At the same time, the magnet 142 is away from the Hall sensor 141, and the Hall sensor 141 cannot sense the magnet 142, so the Hall sensor 141 generates a second Hall signal.

[0182] Step S1420, based on the second Hall signal and the shading signal, determining that the deadlock is locked;

[0183] The control unit 310 receives the second Hall signal at the same time as the light shielding signal. The control unit 310 determines that the deadlock 100 is in the locked state through the light shielding signal, and the control unit 310 assists in determining that the deadlock 100 is in the locked state through the second Hall signal to verify the accuracy of the deadlock 100 being in the locked state.

[0184] Based on any embodiment of the combination lock control method of the present invention, Figure 17 , Figure 14 and Figure 26 The step of receiving at least two shading signals sequentially outputted by the photoelectric sensor within the second predetermined time period further includes the steps of:

[0185] Step S1430, continuously receiving a second Hall signal output by the Hall sensor within the second predetermined time period;

[0186] During the process from the locked state to the locked reset state, within the second predetermined duration, when the control unit 310 drives the gear disk 120 to rotate via the motor 115, since the transmission block 122 on the gear disk 120 does not abut against the linkage block 113 during rotation, the transmission block 122 will not drive the rotating shaft 111 to rotate via the linkage block 113, so that the Hall sensor 141 will continuously fail to sense the magnet 142, and thus continuously generate the second Hall signal.

[0187] Step S1440: Based on the second Hall signal and the at least two light-shielding signals, determine that the deadbolt has completed the locked reset.

[0188] During the process from the locked state to the locked reset state, the control unit 310 sequentially receives the light-shielding signal, the optical signal, and the light-shielding signal output by the photoelectric sensor 114. At the same time, the control unit 310 also continuously receives the second Hall signal. The control unit 310 determines that the deadbolt is in the locked reset state based on the light-shielding signal, the optical signal, and the light-shielding signal output by the photoelectric sensor 114, and the control unit 310 uses the continuously received second Hall signal to assist in determining that the deadbolt is in the locked reset state to verify the accuracy of the deadbolt being in the locked reset state.

[0189] Based on any embodiment of the combined lock control method of the present invention, in combination with Figure 27 , before the step of receiving the target electrical signal detected by the touch control module of the deadbolt, the following steps are included:

[0190] Step S1510: The touch control of the touch control module generates an electrical signal in response to a user operation event.

[0191] When the user locks or unlocks the combined lock 300, the user's hand holds the handle 210, and the user's hand touches the touch control 221 exposed on the handle 210. The touch control 221 generates an electrical signal in response to the user's manipulation event.

[0192] In this embodiment, the touch control 221 is a fingerprint acquisition component. When the user holds the handle 210, one of the user's fingers touches the fingerprint acquisition component, and the fingerprint acquisition component generates an electrical signal in response to the user operation event. The electrical signal carries user feature data, and the user feature data includes the user's fingerprint data.

[0193] Step S1520: The verification unit of the touch control module analyzes and obtains the user feature data carried in the electrical signal, and checks whether the user feature data is the user feature data corresponding to a legitimate user in the identity database. When it belongs, determine that the electrical signal is the target electrical signal.

[0194] The touch control 221 outputs the acquired electrical signal to the verification unit of the touch control module 220. The verification unit verifies whether the user feature data carried in the electrical signal corresponds to the user feature data of a legal user in the identity database. When it does, the electrical signal is determined to be the target electrical signal; otherwise, the electrical signal is determined not to be the target electrical signal. The verification unit outputs the target electrical signal to the control unit 310.

[0195] In this embodiment, the verification unit is a fingerprint verification unit. After receiving the electrical signal output by the fingerprint acquisition component, the fingerprint verification unit extracts the corresponding user feature data from the electrical signal. An identity database containing the user feature data of legal users is preset in the fingerprint verification unit. The fingerprint verification unit compares the user feature data with each piece of user feature data in the identity database. When the acquired user feature data matches one of the user feature data in the identity database, the fingerprint verification unit sets the corresponding electrical signal as the target electrical signal; otherwise, when the acquired user feature data does not match one of the user feature data in the identity database, the fingerprint verification unit sets the corresponding electrical signal as an invalid electrical signal. The fingerprint verification unit outputs the acquired target electrical signal to the control unit 310, and the control unit 310 controls the deadbolt 100 to be unlocked or locked based on the target electrical signal.

[0196] In summary, when the user holds the handle of the latch bolt lock in the combination lock of the present invention, the touch control module on the handle can be touched to trigger the unlocking of the deadbolt, so that during the process of the user operating the handle to unlock the latch bolt lock, the deadbolt can be automatically unlocked synchronously, reducing the unlocking steps of the combination lock and improving the user experience.
