Description

Technical Field

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

[0002] In today's household door lock market, the combination of a dead lock 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 actual daily use, this seemingly secure combination brings many inconveniences 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, a series of complex and cumbersome operation processes must be experienced. First, the user needs to use a knob, a handle or a key to perform a separate unlocking operation on the dead lock. This step seems simple, but actually has relatively high requirements for the user's operation accuracy. 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 be retracted, 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 dead lock, 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 urgently 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 using a dead lock and a latch lock has obvious deficiencies in terms of door opening convenience, 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. Summary of the Invention

[0039] Receive a second Hall signal output by the Hall sensor without responding to the magnet, and the magnet is arranged on the rotating shaft;

[0040] Based on the second Hall signal and the light-shielding signal at the same time, determine that the deadlock has completed the locking.

[0045] Compared with the prior art, the present invention has many advantages, including but not limited to:

[0046] For existing combination locks, to open the door, the user needs to first unlock the deadbolt lock, then unlock the latch bolt lock, and finally pull the handle to open the door. The whole process involves multiple steps. In contrast, with the present invention, through the cooperation of the rotation sensing module and the control unit, the unlocking operation of the deadbolt lock is synchronized with the unlocking operation of the latch bolt lock. The user only needs to hold the handle of the latch bolt lock and turn it. During this process, the rotation sensing module detects the rotation of the transmission shaft and generates a first electrical signal. After receiving this signal, the control unit outputs a drive control signal to the motor of the deadbolt lock, driving the motor to drive the bolt of the deadbolt lock to unlock. This means that while the user unlocks the latch bolt lock, the deadbolt lock is also automatically unlocked, eliminating the need for a separate additional unlocking operation for the deadbolt lock, thus simplifying the originally multi-step unlocking process into one step and significantly reducing the user's operation steps.

[0047] For the vast majority of users, especially the elderly, children, or people with limited mobility, this simplified unlocking method is more user-friendly and convenient. Take the elderly as an example. They may be prone to making mistakes in multi-step operations due to memory decline, resulting in an inability to open the door smoothly. However, with the automatic synchronous unlocking of the present invention, the complexity of the operation is reduced, and the risk of the elderly being unable to open the door due to operation errors is decreased. For children, due to height and strength limitations, they may have difficulty completing some unlocking steps that require a large grip force or precise movements. With the present invention, only a simple action of turning the handle can achieve the unlocking of the entire combination lock, which is more in line with the operating capabilities and habits of children. In addition, for people with limited mobility, reducing the operation steps also means reducing the difficulty and physical exertion of opening the door, enabling them to use the combination lock more easily, thus greatly enhancing the user experience.

[0083] Those skilled in the art of the present technology can understand that, unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meaning as the general understanding of those of ordinary skill in the art to which the present invention belongs. 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.

[0084] The present invention provides a combination lock. When a user holds the handle of the deadbolt lock and rotates the handle, an electric signal is generated by detecting the rotation of the handle through a rotation sensing module, and a control unit controls the deadlock to be unlocked based on the electric signal, so that when the user unlocks the deadbolt lock, the deadlock is synchronously and automatically unlocked, improving the unlocking efficiency of the combination lock and enhancing the user experience.

[0085] In a typical embodiment of the present invention, in combination with Figure 1 and Figure 2 , or, in combination with Figure 3 and Figure 4, the combination lock 300 includes a control unit 310, a deadbolt lock 100, and a latch lock 200. The deadbolt lock 100 and the latch 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 doorframe. There are two lock tongue grooves on the doorframe, which are a first lock tongue groove and a second lock tongue groove respectively. The first lock tongue groove corresponds to the deadbolt lock 100, and the second lock tongue groove corresponds to the latch lock 200.

[0086] The deadbolt lock 100 includes a motor 115, a transmission mechanism (referred to as the first transmission mechanism), and a lock tongue (referred to as the first lock tongue 160). The motor 115, the first transmission mechanism, and the first lock tongue 160 are sequentially connected in transmission. The motor 115 drives the first lock tongue 160 to extend into the first lock tongue groove through the first transmission mechanism to lock the deadbolt lock 100, or the motor 115 drives the first lock tongue 160 to withdraw from the first lock tongue groove through the first transmission structure to unlock the deadbolt lock 100. The control unit 310 is used to control the operation of the motor 115.

[0087] Combined Figure 5 , the latch lock 200 includes a handle 210, a rotation sensing module 260, a transmission mechanism (referred to as the second transmission mechanism), and a lock tongue (referred to as the 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 lock the latch 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 unlock the latch lock 200. The rotation sensing module 260 is electrically connected to the control unit 310.

[0088] Specifically, the second transmission mechanism includes a transmission shaft 240. One end of the transmission shaft 240 is inserted into the handle 210, and the transmission shaft 240 is connected to the second lock tongue 230, and the second lock tongue 230 is arranged 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 lock tongue 230 to move linearly relative to the second lock tongue groove, so that the second lock tongue 230 extends into or withdraws from the second lock tongue groove to lock or unlock the latch lock 200.

[0089] The diagonal tongue lock 200 further includes a housing 270. The transmission shaft 240 passes through the housing 270. The handle 210 is disposed outside the housing 270, and the transmission shaft 240 is inserted into the handle 210, so that the handle 210 is pivotally arranged relative to the housing 270. The rotation sensing module 260 is installed in the housing 270. Since a partial section of the transmission shaft 240 is located in the housing 270, the rotation sensing module 260 can detect the rotation of the transmission shaft 240 in the housing 270 and generate an electrical signal.

[0090] When the handle 210 is in the initial position, the second tongue 230 of the diagonal tongue lock 200 extends into the second tongue 230 groove, so that the diagonal tongue lock 200 is in the locked state. When the handle 210 is in the unlocked position, the second tongue 230 of the diagonal tongue lock 200 withdraws from the second tongue 230 groove, so that the diagonal tongue lock 200 is in the unlocked state.

[0091] In a typical embodiment of the present invention, the diagonal tongue lock 200 further includes a reset mechanism. The reset mechanism is installed in the housing 270 of the diagonal tongue lock 200. The reset mechanism includes a reset torsion spring 271 and a reset block 272. A reset groove 273 is provided in the housing 270. The reset torsion spring 271 is installed in the reset groove 273. The reset block 272 is fixed on the transmission shaft 240. One end of the reset torsion spring 271 is connected to the bottom of the reset groove 273, and the other end of the reset torsion spring 271 is connected to the reset block 272.

[0092] When the diagonal tongue lock 200 is in the locked state, the reset torsion spring 271 is in the initial state. When the reset torsion spring 271 is in the initial state, the reset torsion spring 271 does not store elastic tensile force or elastic retraction force. When the diagonal tongue lock 200 is in the unlocked state, the transmission shaft 240 pulls the reset torsion spring 271 to elongate, so that the reset torsion spring 271 is in the stretched state and the reset torsion spring 271 accumulates elastic retraction force. When the user manipulates the handle 210 to unlock the diagonal tongue lock 200 and no longer applies a force to the handle 210, under the action of the elastic retraction force of the reset torsion spring 271, the reset torsion spring 271 returns from the unlocked state to the initial state. At the same time, the reset torsion spring 271 drives the transmission shaft 240 to rotate, and the transmission shaft 240 will synchronously drive the handle 210 and the second tongue 230 to move, so that the handle 210 returns from the unlocked position to the initial position, and the second tongue 230 also returns from the unlocked state to the locked state. That is to say, by setting the reset mechanism, the diagonal tongue lock 200 in the unlocked state can be automatically returned to the locked state.

[0093] When the user unlocks the combination lock 300, the user holds the handle 210 and applies a force to the handle 210, causing the handle 210 to rotate. The handle 210 drives the transmission shaft 240 to rotate synchronously. The rotation sensing module 260 detects the rotation of the transmission shaft 240 and generates an electrical signal. The rotation sensing module 260 outputs the electrical signal to the control unit 310. The control unit 310 generates a first drive control signal based on the electrical signal and outputs the first drive control signal to the motor 115 of the deadlock 100 to control the operation of the motor 115, thereby controlling the movement of the first locking tongue 160 through the motor 115 and unlocking the deadlock 100.

[0094] Thus, when the user rotates the handle 210 to unlock the latch lock 200, the rotation sensing module 260 generates a corresponding electrical signal by detecting the rotation of the transmission shaft 240. The control unit 310 generates a first drive control signal based on the received electrical signal and controls the operation of the motor 115 through the first drive control signal to drive the first locking tongue 160 to operate through the motor 115, so as to unlock the deadlock 100. It can be understood that when the user rotates the handle 210 to unlock the latch lock 200, the deadlock 100 is also unlocked synchronously, enabling the user to unlock with one step without separately unlocking the deadlock 100 and the latch lock 200 respectively, reducing the unlocking steps of the combination lock 300, improving the unlocking efficiency, and enhancing the user experience.

[0095] In the first embodiment, in combination with Figure 6 , the rotation sensing module 260 includes a Hall sensor (referred to as the first Hall sensor 261) and a magnet (referred to as the first magnet 262). The first magnet 262 is disposed on the transmission shaft 240. When the handle 210 drives the transmission shaft 240 to rotate, the transmission shaft 240 will drive the first magnet 262 to rotate synchronously.

[0096] When the latch lock 200 is in the unlocked state, the first magnet 262 is in the magnet unlocking position; when the latch lock 200 is in the locked state, the first magnet 262 is in the magnet locking position. The first Hall sensor 261 is disposed on the rotation path of the first magnet 262 and is disposed close to the magnet locking position.

[0097] When the handle 210 drives the first magnet 262 to rotate synchronously through the transmission shaft 240, such that the first magnet 262 moves away from the magnet locking position, the first Hall sensor 261 cannot sense the first magnet 262, thereby correspondingly generating an electrical signal (this electrical signal is referred to as the first electrical signal). The first Hall sensor 261 outputs the first electrical signal to the control unit 310. The control unit 310 determines that the deadbolt lock 200 is implementing unlocking based on the first electrical signal. The control unit 310 generates a first drive control signal based on the first electrical signal, controls the operation of the motor through the first drive control signal, and controls the deadlock 100 to implement unlocking synchronously, improving the unlocking efficiency and enhancing the user experience.

[0098] When the reset mechanism drives the first magnet 262 to rotate synchronously through the transmission shaft 240, such that the first magnet 262 returns to the magnet locking position, the first Hall sensor 261 senses the first magnet 262, thereby correspondingly generating an electrical signal (this electrical signal is referred to as the second electrical signal). The first Hall sensor 261 outputs the second electrical signal to the control unit 310. The control unit 310 determines that the deadbolt lock 200 is in the locked state based on the second electrical signal.

[0099] In another embodiment, the first Hall sensor 261 can be replaced by a reed switch sensor. For the specific cooperation relationship between the reed switch sensor and the first magnet 262, please refer to the cooperation relationship between the first Hall sensor 261 and the first magnet 262. To save space, it will not be elaborated here.

[0100] In the second embodiment, in combination with Figure 7 , the rotation sensing module 260 includes a light shielding sheet 264 and a photoelectric sensor (this photoelectric sensor is referred to as the first photoelectric sensor 263). The light shielding sheet 264 is disposed on the transmission shaft 240. When the handle 210 drives the transmission shaft 240 to rotate, the transmission shaft 240 will drive the light shielding sheet 264 to rotate synchronously.

[0101] When the deadbolt lock 200 is in the unlocked state, the light shielding sheet 264 is in the light shielding and unlocking position; when the deadbolt lock 200 is in the locked state, the light shielding sheet 264 is in the light shielding and locking position. The first photoelectric sensor 263 is disposed on the rotation path of the light shielding sheet 264, and the first photoelectric sensor 263 is disposed in the light shielding and locking position.

[0102] When the handle 210 drives the light-shielding piece 264 to rotate synchronously through the transmission shaft 240, so that the light-shielding piece 264 leaves the light-shielding and locking position, the light emitted by the first photoelectric sensor 263 is no longer blocked by the light-shielding piece 264, thereby correspondingly generating an electrical signal (this electrical signal is called the first electrical signal). The first photoelectric sensor 263 outputs the first electrical signal to the control unit 310. The control unit 310 determines that the deadbolt lock 200 is unlocking based on the first electrical signal. The control unit 310 generates a first drive control signal based on the first electrical signal, controls the motor to work through the first drive control signal, and controls the deadlock 100 to unlock synchronously, improving the unlocking efficiency and enhancing the user experience.

[0103] When the reset mechanism drives the light-shielding piece 264 to rotate synchronously through the transmission shaft 240, so that the light-shielding piece 264 returns to the light-shielding and locking position, the light emitted by the first photoelectric sensor 263 is blocked by the light-shielding piece 264, thereby correspondingly generating an electrical signal (this electrical signal is called the second electrical signal). The first photoelectric sensor 263 outputs the second electrical signal to the control unit 310. The control unit 310 determines that the deadbolt lock 200 is in the locked state based on the second electrical signal.

[0104] In the third embodiment, in combination with Figure 8 , the rotation sensing module 260 includes an encoder 265, and the encoder 265 is sleeved on the transmission shaft 240. When the handle 210 drives the transmission shaft 240 to rotate, the transmission shaft 240 will drive the encoder 265 to rotate synchronously.

[0105] When the deadbolt lock 200 is in the unlocked state, the encoder 265 is in the coding unlock position; when the deadbolt lock 200 is in the locked state, the encoder 265 is in the coding lock position.

[0106] When the handle 210 drives the encoder 265 to rotate synchronously through the transmission shaft 240, so that the encoder 265 leaves the coding lock position, the encoder 265 correspondingly generates an electrical signal (this electrical signal is called the first electrical signal). The encoder 265 outputs the first electrical signal to the control unit 310. The control unit 310 determines that the deadbolt lock 200 is unlocking based on the first electrical signal. The control unit 310 generates a first drive control signal based on the first electrical signal, controls the motor to work through the first drive control signal, and controls the deadlock 100 to unlock synchronously, improving the unlocking efficiency and enhancing the user experience.

[0107] When the reset mechanism drives the encoder 265 to rotate synchronously through the transmission shaft 240, so that the encoder 265 returns to the encoding and locking position, the encoder 265 correspondingly generates an electrical signal (this electrical signal is called the second electrical signal). The encoder 265 outputs the second electrical signal to the control unit 310, and the control unit 310 determines that the deadbolt lock 200 is in the locked state based on the second electrical signal.

[0108] In the fourth embodiment, in combination with Figure 9 , the rotation sensing module 260 includes a microswitch 266 and a trigger portion 267 disposed on the transmission shaft 240. The trigger portion 267 is disposed on the transmission shaft 240. When the handle 210 drives the transmission shaft 240 to rotate, the transmission shaft 240 will drive the trigger portion 267 to rotate synchronously.

[0109] When the deadbolt lock 200 is in the unlocked state, the trigger portion 267 is in the trigger unlocking position; when the deadbolt lock 200 is in the locked state, the trigger portion 267 is in the trigger locking position. The microswitch 266 is disposed on the rotation path of the trigger portion 267, and the microswitch 266 is disposed close to the trigger locking position.

[0110] When the handle 210 drives the trigger portion 267 to rotate synchronously through the transmission shaft 240, so that the trigger portion 267 leaves the trigger locking position, the microswitch 266 can no longer be triggered by the trigger portion 267, thereby correspondingly generating an electrical signal (this electrical signal is called the first electrical signal). The microswitch 266 outputs the first electrical signal to the control unit 310. The control unit 310 determines that the deadbolt lock 200 is being unlocked based on the first electrical signal. The control unit 310 generates a first drive control signal based on the first electrical signal, controls the motor to work through the first drive control signal, and controls the deadlock 100 to be unlocked synchronously, improving the unlocking efficiency and enhancing the user experience.

[0111] When the reset mechanism drives the trigger portion 267 to rotate synchronously through the transmission shaft 240, so that the trigger portion 267 returns to the trigger locking position, the microswitch 266 is triggered by the trigger portion 267, thereby correspondingly generating an electrical signal (this electrical signal is called the second electrical signal). The microswitch 266 outputs the second electrical signal to the control unit 310, and the control unit 310 determines that the deadbolt lock 200 is in the locked state based on the second electrical signal.

[0112] Thus, from the specific implementation manners of the first embodiment, the second embodiment, the third embodiment, and the fourth embodiment, it can be seen that the rotation sensing module 260 described in the present invention has various implementation forms. After those skilled in the art understand the technical solution of the present invention, various deformation and improvement solutions that can be conceived without creative labor based on the technical concept of the present invention should be regarded as falling within the protection scope defined by the present invention.

[0113] In a typical embodiment of the present invention, the control unit 310 is installed in the deadlock 100. Since the deadlock 100 and the latch lock 200 are separately provided, a wired connection or a wireless connection is established between the control unit 310 installed in the deadlock 100 and the rotation sensing module 260 installed in the latch lock 200.

[0114] In one embodiment, in combination with Figure 1 and Figure 2 , the control unit 310 and the rotation sensing module 260 are wirelessly connected. Specifically, a first communication unit 170 is further provided in the deadlock 100, and the first communication unit 170 is electrically connected to the control unit 310; a second communication unit 250 is provided in the latch lock 200, and the second communication unit 250 is electrically connected to the rotation sensing module 260, and a wireless communication connection is established between the first communication unit 170 and the second communication unit 250. The control unit 310 and the rotation sensing module 260 perform data communication through 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 achieve good data communication at a short distance. For example, both the first communication unit 170 and the second communication unit 250 are radio frequency devices, but it should not be construed as a limitation of the present invention.

[0115] In another embodiment, in combination with Figure 3 and Figure 4 , the control unit 310 and the rotation sensing module 260 are wired-connected. Specifically, the control unit 310 and the rotation sensing module 260 are connected by a cable 320 to enable good data interaction between the control unit 310 and the rotation sensing module 260. In this embodiment, the cable 320 can be arranged in the door body 400 to avoid interference from the external environment to the cable 320 and extend the service life of the cable 320. In this embodiment, it is recommended that the cable 320 is an electronic wire harness, but it should not be construed as a limitation of the present invention.

[0116] In a typical embodiment of the present invention, in combination with Figure 10 , Figure 11 and Figure 13, the deadlock 100 includes the first transmission mechanism and the first locking tongue 160. The first transmission mechanism includes the lock core dial 150. The lock core dial 150 is connected to the first locking tongue 160. The lock core dial 150 drives the first locking tongue 160 to move linearly along the extending direction of the first locking tongue 160, so that the first locking tongue 160 extends into or withdraws from the first locking tongue groove, thereby realizing the locking or unlocking of the deadlock 100.

[0117] The lock core dial 150 is perpendicularly arranged with the first locking tongue 160, and the lock core dial 150 is fixedly arranged with the first locking tongue 160. Combining Figure 12 , the lock core dial 150 is of a flat columnar structure. The lock core dial 150 includes adjacent unlocking surface 151 and 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 dial 150 is rotated so that the unlocking surface 151 of the lock core dial 150 faces the first locking tongue groove, the first locking tongue 160 withdraws from the first locking tongue groove to realize unlocking; when the lock core dial 150 is rotated so that the locking surface 152 of the lock core dial 150 faces the first locking tongue groove, the first locking tongue 160 extends into the first locking tongue groove to realize locking.

[0118] In a typical embodiment of the present invention, combining Figure 13 , the first transmission mechanism further includes a rotating shaft 111, a gear disk 120, a linkage block 113, a photoelectric sensor 114 (referred to as the second photoelectric sensor 114), a motor 115 and a control unit 310. The control unit 310 is electrically connected to the second photoelectric sensor 114 and the motor 115 respectively. The motor 115 is used to drive the gear disk 120 to rotate. Combining Figure 2 , the rotating shaft 111 is connected to the lock core dial 150. Combining Figure 16 , the linkage block 113 is arranged on the rotating shaft 111. The gear disk 120 is provided with a gear hole. The gear disk 120 is sleeved on the rotating shaft 111 through the gear hole. The gear hole is a circular hole. 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 cooperation between the gear hole and the rotating shaft 111, so that the gear disk 120 cannot directly drive the rotating shaft 111 to rotate.

[0119] Combining Figure 14 and Figure 16, 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.

[0120] Combined with Figure 14 and Figure 15 , a plurality of light blocking sheets 130 are provided on the toothed disc 120, and the toothed disc 120 will drive the light blocking sheets 130 to rotate synchronously. The second photoelectric sensor 114 is arranged on the rotation path of the light blocking sheets 130. When the toothed disc 120 drives the light blocking sheet 130 to pass by the second photoelectric sensor 114, the light blocking sheet 130 will block the light emitted by the second photoelectric sensor 114, so that the second photoelectric sensor 114 generates a light blocking signal. The second photoelectric sensor 114 outputs the light blocking signal to the control unit 310, and the control unit 310 obtains the rotation angle of the toothed disc 120 based on the light blocking signal and judges the working state of the dead lock 100.

[0121] In this embodiment, a plurality of light blocking sheets 130 are provided on the toothed disc 120, and the plurality of light blocking sheets 130 are evenly arranged in the circumferential direction of the toothed disc 120. For example, if two light blocking sheets 130 are provided on the toothed disc 120, the two light blocking sheets 130 are arranged at 180°; if three light blocking sheets 130 are provided on the toothed disc 120, the three light blocking sheets 130 are arranged in sequence along the circumferential direction of the toothed disc 120, and the adjacent two light blocking sheets 130 are arranged at 120°.

[0122] 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 second 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 second photoelectric sensor 114 is blocked by another light shielding plate 130, the control unit 310 receives the light shielding signal output by the second photoelectric sensor 114, and the control unit 310 determines that the toothed disc 120 has rotated 90°.

[0123] The control unit 310 controls the forward and reverse rotation of the motor 115 by outputting the driving control signal to the motor 115, so as to control the rotation direction of the toothed disc 120. 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 withdraw from 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 second 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.

[0124] In this embodiment, combined with Figure 14 , 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.

[0125] 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.

[0126] Combination Figure 13 and Figure 16 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.

[0127] Combination Figure 14 and Figure 16 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.

[0128] 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.

[0129] In order to facilitate the description of the working principle of the deadbolt 100 of the present invention, Figure 18 and Figure 19 , Figure 18This is a plan view of the assembly of the rotating shaft, linkage ring, and second photoelectric sensor. Figure 19 It is a plan schematic diagram of the toothed disc 120, assuming that the four light blocking plates 130 on the toothed disc 120 are respectively the first light blocking plate 131, the second light blocking plate 132, the third light blocking plate 133 and the fourth light blocking plate 134 along the circumferential direction of the toothed disc 120, and assuming that the two end surfaces 1221 of the transmission block 122 are respectively the first end surface 1222 and the second end surface 1223.

[0130] Combination Figure 20 , assuming that the deadbolt 100 is in the locked reset state, the first light shielding sheet 131 is located at the second photoelectric sensor 114, the second photoelectric sensor 114 generates a light shielding signal, and the control unit 310 determines that the deadbolt 100 is in the locked reset state based on the light shielding signal. In addition, the first end surface 1222 abuts against the linkage block 113 of the linkage ring 118.

[0131] Combination Figure 20 and Figure 21 When the deadbolt 100 needs to be unlocked, the control unit 310 outputs the driving control signal to the motor 115 to control the motor 115 to rotate forward, and the motor 115 drives the toothed disc 120 to rotate 90° counterclockwise, 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. Among them, the first light shielding sheet 131 on the toothed disc 120 will leave the second photoelectric sensor 114, and the second 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 second 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 second photoelectric sensor 114, and the fourth light shielding plate 134 will shield the light emitted by the second photoelectric sensor 114, generating a light shielding signal again. The control unit 310 receives the light shielding signal, determines that the fourth light shielding plate 134 has rotated to the second photoelectric sensor 114, and determines that the deadlock 100 has been unlocked. 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 the unlocking, so that the deadlock 100 is in an unlocked state.

[0132] Combination Figure 21 and Figure 22, 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 rotates clockwise by 180° synchronously 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 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 clockwise by 180°, the fourth light blocking piece 134 will leave the second photoelectric sensor 114, so that the second photoelectric sensor 114 generates a photoelectric signal, and the first light blocking piece 131 and the second light blocking piece 132 pass through the second photoelectric sensor 114 in sequence. The second 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 second photoelectric sensor 114. The control unit 310 sequentially receives the photoelectric signal and the light blocking signal output by the second photoelectric sensor 114. Thus, the control unit 310 correspondingly judges that the deadbolt 100 is in the unlocked and reset state, preparing for locking the deadbolt 100 later.

[0133] Combined with Figure 22 and Figure 23, when the deadlock 100 is in the unlocked and reset state and the deadlock 100 needs to be locked, the control unit 310 outputs the drive control signal to the motor 115 to control the motor 115 to reverse. 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°. The linkage block 113 drives the linkage ring 118, the rotating shaft 111, the lock core dial 150 and the first lock tongue 160 to move synchronously, so that the first lock tongue 160 extends out of the first lock tongue groove and inserts into the first lock 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 second photoelectric sensor 114, so that the second photoelectric sensor 114 generates a photoelectric signal; then the third light shielding piece 133 will rotate clockwise by 90° to the second photoelectric sensor 114, and the second photoelectric sensor 114 correspondingly generates a light shielding signal, and the third light shielding piece 133 stays at the second photoelectric sensor 114. The control unit 310 sequentially receives the photoelectric signal and the light shielding signal output by the second photoelectric sensor 114. Thus, the control unit 310 correspondingly determines that the deadlock 100 is in the locked state.

[0134] Combined with Figure 23 and Figure 20, 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 shielding piece 133 will leave the second photoelectric sensor 114, so that the second photoelectric sensor 114 generates a photoelectric signal, and the second light shielding piece 132 and the first light shielding piece 131 pass through the second photoelectric sensor 114 in sequence. The second 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 second photoelectric sensor 114. The control unit 310 receives the photoelectric signal and the light shielding signal output by the second 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.

[0135] Thus, the above text describes the whole process of the deadbolt 100 of the present invention from the locked and reset state - unlocking state - unlocking and reset state - locked state - locked and reset state. The deadbolt 100 can judge the state of the deadbolt 100 through the received photoelectric signal and light shielding signal, so that the control unit 310 can accurately control the operation of the deadbolt 100 only through a single second photoelectric sensor 114, reducing the number of sensors of the deadbolt 100 and lowering the production cost of the deadbolt 100.

[0136] In one embodiment, combined with Figures 15 to 18 , the deadbolt 100 is further provided with a second Hall sensor (referred to as the second Hall sensor 141) and a magnet (referred to as the second magnet 142). The second magnet 142 is arranged on the rotating shaft 111. When the rotating shaft 111 rotates, the rotating shaft 111 will drive the second magnet 142 to rotate synchronously. The second Hall sensor 141 is arranged on the rotation path of the second magnet 142. When the second magnet 142 approaches the second Hall sensor 141, the second Hall sensor 141 will generate a Hall signal.

[0137] In this embodiment, the second Hall sensor 141 is disposed adjacent to the second photoelectric sensor 114, and the second Hall sensor 141 is disposed at a 90° angle with respect to the first locking tongue groove. The second 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 second magnet 142 and the orientation of the locking surface 152 of the lock core dial 150 are set to be the same.

[0138] Combined with Figure 20 and Figure 21 , 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 deadbolt lock 100 is unlocked. At the same time, the locking surface 152 of the rotating shaft 111 faces the second Hall sensor 141, the second magnet 142 approaches the second Hall sensor 141, the second Hall sensor 141 senses the second magnet 142, generates a first Hall signal, and when the control unit 310 receives the first Hall signal, it determines that the deadbolt lock 100 is in the unlocked state.

[0139] Combined with Figure 22 and Figure 23 , 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 deadbolt lock 100 is locked. At the same time, the second magnet 142 moves away from the second Hall sensor 141, and the second Hall sensor 141 cannot sense the second magnet 142. Therefore, the second Hall sensor 141 generates a second Hall signal, and when the control unit 310 receives the second Hall signal, it determines that the deadbolt lock 100 is in the locked state.

[0140] Thus, the deadbolt lock 100 of the present invention can use the second Hall sensor 141 to assist in determining whether the deadbolt lock 100 is in the locked state, the locked reset state, the unlocked state, and the unlocked reset state, so that the control unit 310 can accurately monitor the state of the deadbolt lock 100.

[0141] In one embodiment, combined with Figure 10 , Figure 11 and Figure 13The deadbolt lock 100 further includes a housing 143 and a knob 144. The shaft 111, the toothed disc 120, the linkage ring 118, the second photoelectric sensor 114, the second 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 disposed 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.

[0142] 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.

[0143] In a further embodiment, in combination Figure 10 , Figure 18 , Figures 20 to 13 , 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.

[0144] In one embodiment, in combination Figure 13 and Figure 17, a bottom plate 1431 is further provided on the outer shell 143. A pivot hole 1432 is provided on the bottom plate 1431. The knob 144 is arranged on the outer side surface of the bottom plate 1431. The rotating shaft 111 passes through the pivot hole 1432 to be inserted into the knob 144, so that the knob 144 is pivotally arranged relative to the bottom plate 1431. Bearing grooves 1433 are respectively formed on both sides of the bottom plate 1431, that is to say, the two bearing grooves 1433 are respectively arranged on the inner side surface and the outer side surface of the bottom plate 1431, and the two bearing grooves 1433 are coaxially arranged with the pivot hole 1432.

[0145] Bearings 147 are installed in the two bearing grooves 1433. The bearings 147 are in close fit with the corresponding bearing grooves 1433. The bearings 147 are sleeved on the rotating shaft, and the bearings 147 are also in close fit with the rotating shaft 111. Since the two bearings 147 are respectively in close fit with the corresponding bearing grooves 1433 and the rotating shaft, the rotating shaft 111 is also in close fit with the pivot hole 1432, solving the problem of shaking of the rotating shaft 111 during rotation. In addition, since there is a bearing 147 between the knob 144 and the bottom plate 1431, the friction between the knob 144 and the bottom plate 1431 will not be increased after the knob 144 is rotated under force, avoiding affecting the rotation feel of the knob 144 and increasing the driving resistance of the motor, and improving the user experience.

[0146] In one embodiment, in combination with Figure 13 and Figure 15 , a circuit board 146 is further provided in the deadbolt lock 100. The circuit board 146 is installed in the outer shell 143. The second photoelectric sensor 114 and the second Hall sensor 141 are both integrated on the circuit board 146.

[0147] The present invention also provides a combination lock unlocking control method. The combination lock unlocking control method is implemented based on the combination lock 300 described above, and the control unit 310 of the combination lock 300 is used to execute the combination lock unlocking control method, so that when the user holds the handle 210 of the deadbolt lock 200 and rotates the handle 210, the rotation induction module 260 in the deadbolt lock 200 will detect the rotation of the transmission shaft 240 that rotates synchronously with the handle 210. The rotation induction module 260 generates a corresponding electrical signal, and the control unit 310 synchronously controls the deadbolt lock 100 to be unlocked based on the electrical signal, so that the deadbolt lock 200 and the deadbolt lock 100 can be unlocked simultaneously, reducing the unlocking steps and improving the user experience.

[0148] In a typical embodiment of the present invention, in combination with Figure 24 , the combination lock unlocking control method includes the following specific steps:

[0149] Step S1000: Receive a first electrical signal generated by the rotation induction module of the deadbolt lock detecting the rotation of the transmission shaft of the deadbolt lock. The handle of the deadbolt lock drives the transmission shaft to rotate synchronously.

[0150] When the user needs to unlock or lock the combination lock, the user holds the handle 210 of the deadbolt lock 200 and applies a force to the handle 210, causing the handle 210 to drive the transmission shaft 240 to rotate synchronously. The rotation induction module 260 detects the rotation of the transmission shaft 240 and generates a first electrical signal. The rotation induction module 260 outputs the first electrical signal to the control unit 310.

[0151] Based on the first embodiment described above, the handle 210 drives the first magnet 262 to rotate synchronously via the transmission shaft 240. When the first magnet 262 leaves the magnet locking position, the first Hall sensor 261 cannot sense the first magnet 262, thereby generating a first electrical signal correspondingly.

[0152] Based on the second embodiment described above, the handle 210 drives the light shielding piece 264 to rotate synchronously via the transmission shaft 240. When the light shielding piece 264 leaves the light shielding and locking position, the light emitted by the first photoelectric sensor 263 is no longer blocked by the light shielding piece 264, thereby generating a first electrical signal correspondingly.

[0153] Based on the third embodiment described above, the handle 210 drives the encoder 265 to rotate synchronously via the transmission shaft 240. When the encoder 265 leaves the encoding and locking position, the encoder 265 generates a first electrical signal correspondingly.

[0154] Based on the fourth embodiment described above, the handle 210 drives the trigger part 267 to rotate synchronously via the transmission shaft 240. When the trigger part 267 leaves the trigger and locking position, the micro switch 266 can no longer be triggered by the trigger part 267, thereby generating a first electrical signal correspondingly.

[0155] Step S2000: In response to the first electrical signal, output a drive control signal to the motor of the deadlock to drive the motor to drive the lock tongue of the deadlock to unlock.

[0156] After receiving the target electrical signal, the control unit 310 obtains the current state of the deadlock 100. For example, the deadlock 100 is currently in any one of the locked reset state, locked state, unlocked state, and unlocked reset state.

[0157] When the control single-chip 310 obtains that the deadlock 100 is in the locked and reset state, the control unit 310 generates a first drive control signal based on the first 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 through the motor 115, and drives the first locking tongue 160 of the deadlock 100 to withdraw from the first locking tongue groove through the first transmission mechanism, so that the deadlock 100 completes unlocking. Moreover, the user holds the handle 210 of the latch lock 200 at the same time, turns the handle 210, and completes the unlocking of the latch lock 200. Thus, while the user completes the unlocking of the latch lock 200, the control unit 310 controls the deadlock 100 to complete unlocking, so that the user does not need to unlock the deadlock 100 separately, reducing the unlocking steps and improving the user experience.

[0158] Based on any embodiment of the combined lock unlocking control method of the present invention, combined with Figure 20 、 Figure 21 and Figure 25 , in the step of outputting a drive control signal to the motor of the deadlock to drive the motor to drive the locking tongue of the deadlock to unlock, the following specific steps are included:

[0159] Step S2100, controlling the motor to drive the gear disk to rotate in the first direction, and the gear disk drives the lock core dial to rotate a first angle through the linkage ring. The lock core dial drives the locking tongue to unlock. The linkage ring is sleeved on the rotating shaft. The lock core dial is linked with the rotating shaft and the locking tongue respectively. A travel groove is provided on the gear disk, and the travel groove is set to span a preset angle along the rotation direction of the gear disk. The linkage block fixed on the linkage ring is inserted into the travel groove;

[0160] When the deadlock 100 is in the locked and reset state, after the control unit 310 receives the first electrical signal output by the rotation induction module 260, the control unit 310 generates a first drive control signal based on the first 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 deadlock 100 completes unlocking.

[0161] Specifically, when the deadlock 100 is in the locked and reset state, the first light blocking piece 131 is at the second photoelectric sensor 114, the second 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.

[0162] 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 operate 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 counterclockwise (in the first direction) by 90°. 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.

[0163] Step S2200: Receive the light-shielding signal output by the photoelectric sensor when blocked by the light-shielding sheet. A plurality of light-shielding sheets are provided on the toothed disc, and the plurality of light-shielding sheets are evenly arranged along the circumferential direction of the toothed disc;

[0164] The first light-shielding sheet 131 on the toothed disc 120 will leave the second photoelectric sensor 114, and the second 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 sheet 131 has left the position of the second photoelectric sensor 114. At the same time, the fourth light-shielding sheet 134 on the toothed disc 120 will rotate counterclockwise by 90° to the position of the second photoelectric sensor 114, and the fourth light-shielding sheet 134 will block the light emitted by the second photoelectric sensor 114 and generate a light-shielding signal again.

[0165] Step S2300: Based on the light-shielding signal, determine that the deadlock is unlocked;

[0166] 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 has rotated to the position of the second photoelectric sensor 114, and determines that the deadlock 100 is unlocked. At the same time, the first end face 1222 on the toothed disc 120 also drives the linkage ring 118, the rotating shaft 111, the first lock core 150, and the first lock tongue 160 to rotate, so that the first lock tongue 160 retracts relative to the first lock tongue groove to complete the unlocking, and the deadlock 100 is in an unlocked state.

[0167] At the same time, the user also holds the handle 210 of the deadbolt lock 200 and rotates the handle 210 to synchronously unlock the deadbolt lock 200. It can be understood that during the process of the user rotating the handle 210 to unlock the deadbolt lock 200, the rotation sensing module 260 detects the rotation of the transmission shaft 240 that rotates synchronously with the handle 210, and the control unit controls the deadlock 100 to be unlocked based on the electrical signal generated by the rotation sensing module, so that the deadbolt lock 200 and the deadlock 100 of the combination lock 300 are synchronously unlocked, reducing the steps for the user to unlock the deadlock 100 and simplifying the unlocking steps of the combination lock 300, improving the user experience.

[0168] Based on any embodiment of the unlocking control method of the combination lock of the present invention, combined with Figure 21 , Figure 22 and Figure 26 , after the step of determining that the deadlock is unlocked, the following specific steps are further included:

[0169] Step S2400, generate a reset instruction;

[0170] 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 work 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 unlocked reset state.

[0171] Step S2500, based on the unlocking reset instruction, control the motor to drive the toothed 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;

[0172] The control unit 310 controls the motor 115 to reverse based on the unlocking reset instruction. The motor 115 drives the toothed disk 120 to rotate 180° clockwise (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 toothed 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 toothed disk 120 does not drive the linkage ring 118, the rotating shaft 111, the first lock core 150 and the first lock tongue 160 to rotate through the linkage block 113.

[0173] Step S2600, receive at least two light-shielding signals sequentially output by the photoelectric sensor within a first predetermined time period;

[0174] The control unit 310 controls the rotation speed of the motor 115 based on the unlocking reset instruction, and correspondingly obtains a 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 shielding piece 134 will leave the second photoelectric sensor 114, causing the second photoelectric sensor 114 to generate a photoelectric signal, and the first light shielding piece 131 and the second light shielding piece 132 will sequentially pass through the second photoelectric sensor 114. The second 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 second photoelectric sensor 114.

[0175] Step S2700, based on the at least two light shielding signals, determine that the deadlock has completed unlocking and resetting;

[0176] The control unit 310 sequentially receives the light shielding signal, the photoelectric signal, and the light shielding signal output by the second photoelectric sensor 114. Thus, the control unit 310 correspondingly determines that the deadlock 100 is in the unlocking and resetting state, preparing for locking the deadlock 100 later.

[0177] On the basis of any embodiment of the combined lock unlocking control method of the present invention, combined with Figure 20 、 Figure 21 and Figure 27 , in the step of receiving the light shielding signal output by the photoelectric sensor when blocked by the light shielding piece, there are also parallel steps:

[0178] Step S2310, receive a first Hall signal output by a Hall sensor in response to a magnet, the magnet being disposed on the rotating shaft;

[0179] 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, such 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 second Hall sensor 141, the second magnet 142 approaches the second Hall sensor 141, and the second Hall sensor 141 senses the second magnet 142 and generates a first Hall signal.

[0180] Step S2320, simultaneously based on the first Hall signal and the light shielding signal, determine that the deadlock has completed unlocking;

[0181] 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 310 uses the first Hall signal to assist in determining that the deadbolt 100 is in the unlocked state, so as to verify the accuracy of the deadbolt 100 being in the unlocked state.

[0182] Based on any embodiment of the combination lock unlocking control method of the present invention, in combination with Figure 21 、 Figure 22 and Figure 28 , in the step of receiving at least two light-shielding signals sequentially output by the photoelectric sensor within the first predetermined time period, there are also parallel steps:

[0183] Step S2610, within the first predetermined time period, continuously receive the first Hall signal output by the Hall sensor;

[0184] 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 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 second Hall sensor 141 will continuously sense the second magnet 142, and thus continuously generate the first Hall signal.

[0185] Step S2620, based on the first Hall signal and the at least two light-shielding signals, determine that the deadbolt has completed unlocking and resetting;

[0186] 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 second 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 second photoelectric sensor 114, and the control unit 310 uses the continuously received first Hall signal to assist in determining that the deadbolt 100 is in the unlocked and reset state, so as to verify the accuracy of the deadbolt 100 being in the unlocked and reset state.

[0187] Based on any embodiment of the combination lock unlocking control method of the present invention, after the step of responding to the first electrical signal and outputting a first drive control signal to the motor of the deadbolt to drive the motor to drive the bolt of the deadbolt to unlock, the following steps are further included:

[0188] Step S3000: Receive the second electrical signal generated by the rotation induction module detecting the rotation of the transmission shaft, and determine that the deadbolt lock is in the locked state based on the second electrical signal.

[0189] When the deadbolt lock 200 is in the unlocked state, the transmission shaft 240 drives the return torsion spring 271 to elongate, so that the return torsion spring 271 is in a stretched state, and the return torsion spring 271 accumulates elastic retraction force. When the user manipulates the handle 210 to unlock the deadbolt lock 200 and no longer applies a force to the handle 210, under the action of the elastic retraction force of the return torsion spring 271, the return torsion spring 271 returns from the unlocked state to the initial state. At the same time, the return torsion spring 271 drives the transmission shaft 240 to rotate, and the transmission shaft 240 will synchronously drive the handle 210 and the second locking tongue 230 to move, so that the handle 210 returns from the unlocked position to the initial position, and the second locking tongue 230 also returns from the unlocked state to the locked state. That is to say, by setting the reset mechanism, the deadbolt lock 200 in the unlocked state can be automatically returned to the locked state. The reset mechanism drives the transmission shaft 240 to rotate, and the rotation induction module 260 detects the rotation of the transmission shaft 240 and generates a second electrical signal. The rotation induction module 260 outputs the second electrical signal to the control unit 310.

[0190] Based on the first embodiment described above, when the reset mechanism synchronously drives the first magnet 262 to rotate through the transmission shaft 240, so that the first magnet 262 returns to the magnet locked position, the first Hall sensor 261 senses the first magnet 262, and thus a second electrical signal is correspondingly generated. The first Hall sensor 261 outputs the second electrical signal to the control unit 310, and the control unit 310 determines that the deadbolt lock 200 is in the locked state based on the second electrical signal.

[0191] Based on the second embodiment described above, when the reset mechanism synchronously drives the light shielding piece 264 to rotate through the transmission shaft 240, so that the light shielding piece 264 returns to the light shielding locked position, the light emitted by the first photoelectric sensor 263 is blocked by the light shielding piece 264, and thus a second electrical signal is correspondingly generated. The first photoelectric sensor 263 outputs the second electrical signal to the control unit 310, and the control unit 310 determines that the deadbolt lock 200 is in the locked state based on the second electrical signal.

[0192] Based on the third embodiment described above, when the reset mechanism synchronously drives the encoder 265 to rotate via the transmission shaft 240, such that the encoder 265 returns to the encoded locking position, the encoder 265 correspondingly generates a second electrical signal. The encoder 265 outputs the second electrical signal to the control unit 310, and the control unit 310 determines that the deadbolt lock 200 is in the locked state based on the second electrical signal.

[0193] Based on the fourth embodiment described above, when the reset mechanism synchronously drives the actuating portion 267 to rotate via the transmission shaft 240, such that the actuating portion 267 returns to the actuating locking position, the microswitch 266 is actuated by the actuating portion 267, thereby correspondingly generating a second electrical signal. The microswitch 266 outputs the second electrical signal to the control unit 310, and the control unit 310 determines that the deadbolt lock 200 is in the locked state based on the second electrical signal.

[0194] Based on any embodiment of the combined lock unlocking control method of the present invention, in combination with Figure 22 , Figure 23 and Figure 29 , after the step of outputting a drive control signal to the motor of the deadlock to drive the motor to drive the bolt of the deadlock to unlock, the following steps are included:

[0195] Step S4100, generating a locking instruction at a predetermined time;

[0196] The control unit 310 can obtain the standard time of the country or region where the combined lock 300 is located. When the country or region is at the predetermined time of the local standard time, the control unit 310 generates a locking instruction and controls the deadlock to complete locking based on the locking instruction.

[0197] For example, when the combined lock 300 is located in China, the control unit 310 obtains the standard time in China, namely Beijing time. Assuming the predetermined time is 0 o'clock, that is to say, when it is midnight, the control unit 310 automatically generates a locking instruction to control the deadlock 100 to complete locking, so as to prevent theft or protect indoor personnel or items at night and improve security.

[0198] Step S4200, based on the locking instruction, controlling the motor to drive the gear disk to rotate in the second direction, and the gear disk drives the lock core dial to rotate by a third angle via the linkage ring. The lock core dial drives the bolt to unlock. The linkage ring is sleeved on the rotating shaft, and the lock core dial is linked with the rotating shaft and the bolt 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;

[0199] When the deadlock 100 is in the unlocked and reset state, after the control unit 310 receives the locking instruction, the control unit 310 generates a second drive control signal based on the locking instruction, and the control unit 310 outputs the second drive control signal to the motor 115 to control the motor 115 to operate, so that the deadlock 100 is unlocked.

[0200] Specifically, when the deadlock 100 is in the unlocked and reset state and 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. 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°. The linkage block 113 drives the linkage ring 118, the rotating shaft 111, the first lock core 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 inserts into the first lock tongue groove, thereby making the deadlock 100 in the locked state.

[0201] Step S4300: Receive the light-shielding signal output by the photoelectric sensor blocked by the light-shielding piece. A plurality of light-shielding pieces are provided on the gear disk, and the plurality of light-shielding pieces are uniformly arranged along the circumferential direction of the gear disk.

[0202] During the process of the gear disk 120 rotating clockwise by 90°, the second light-shielding piece 132 will leave the second photoelectric sensor 114, so that the second photoelectric sensor 114 generates a photoelectric signal. Then the third light-shielding piece 133 will rotate clockwise by 90° to the position of the second photoelectric sensor 114, and the second photoelectric sensor 114 correspondingly generates a light-shielding signal, and the third light-shielding piece 133 stays at the position of the second photoelectric sensor 114.

[0203] Step S4400: Based on the light-shielding signal, determine that the deadlock is locked.

[0204] The control unit 310 sequentially receives the photoelectric signal and the light-shielding signal output by the second photoelectric sensor 114. Thus, the control unit 310 correspondingly determines that the deadlock 100 is in the locked state.

[0205] On the basis of any embodiment of the combined lock unlocking control method of the present invention, combined with Figure 23 、 Figure 20 and Figure 30 After the step of determining that the deadlock is locked, the following steps are further included:

[0206] Step S4500: Generate a locking and reset instruction.

[0207] After the control unit 310 determines that the deadbolt 100 is in the locked state, the control unit 310 generates a locked state reset instruction. The control unit 310 controls the operation of the motor 115 based on the locked state reset instruction, and drives the first transmission mechanism through the motor 115, so that the deadbolt 100 moves from the locked state to the locked state reset state.

[0208] Step S4600, based on the locked state reset instruction, control 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;

[0209] The control unit 310 controls the motor 115 to rotate forward based on the locked state 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 will be linked with the linkage block 113, so that the gear disk 120 will not drive the linkage ring 118, the rotating shaft 111, the first lock core 150 and the first lock tongue 160 to rotate through the linkage block 113.

[0210] Step S4700, receive at least two light-shielding signals sequentially output by the photoelectric sensor within a second predetermined time period;

[0211] The control unit 310 controls the rotation speed of the motor 115 based on the unlock 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 second photoelectric sensor 114, so that the second 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 second photoelectric sensor 114. The second 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 second photoelectric sensor 114.

[0212] Step S4800, based on the at least two light-shielding signals, determine that the deadbolt has completed the locked state reset;

[0213] The control unit 310 sequentially receives the photoelectric signal and the light-shielding signal output by the second photoelectric sensor 114. Therefore, the control unit 310 correspondingly determines that the deadbolt 100 is in the locked state reset state, preparing for unlocking the deadbolt 100 later.

[0214] Based on any embodiment of the unlocking control method of the combination lock of the present invention, in combination with Figure 22 , Figure 23 and Figure 31 , in the step of receiving the light-shielding signal output by the optoelectronic sensor when blocked by the light-shielding piece, the following steps in parallel are further included:

[0215] Step S5100, receiving a second Hall signal output by the Hall sensor without responding to the magnet, where the magnet is arranged on the rotating shaft;

[0216] During the process of the deadlock 100 from the unlocked reset state to the locked state, when the control unit 310 controls the motor 115 to work, the motor 115 drives the first locking tongue 160 through the gear disk 120, the rotating shaft 111 and the first lock core 150, so that the locking surface 152 of the first locking tongue 160 faces the first locking tongue groove, and the first locking tongue 160 extends into the first locking tongue groove, and the deadlock 100 is locked. At the same time, the second magnet 142 moves away from the second Hall sensor 141, and the second Hall sensor 141 cannot sense the second magnet 142, so the second Hall sensor 141 generates a second Hall signal.

[0217] Step S5200, based on the second Hall signal and the light-shielding signal at the same time, judging that the deadlock is locked;

[0218] When receiving the light-shielding signal, the control unit 310 also receives the second Hall signal. The control unit 310 judges that the deadlock 100 is in the locked state through the light-shielding signal, and the control unit 310 uses the second Hall signal to assist in judging that the deadlock 100 is in the locked state to verify the accuracy of the deadlock 100 being in the locked state.

[0219] Based on any embodiment of the unlocking control method of the combination lock of the present invention, in combination with Figure 23 , Figure 20 and Figure 32 , in the step of receiving at least two light-shielding signals sequentially output by the optoelectronic sensor within a second predetermined time period, the following steps in parallel are further included:

[0220] Step S5300, continuously receiving the second Hall signal output by the Hall sensor within the second predetermined time period;

[0221] When the deadbolt lock 100 is in the process from the locked state to the locked reset state, within the second predetermined time period, 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 second Hall sensor 141 will continuously fail to sense the second magnet 142, and thus continuously generate the second Hall signal.

[0222] Step S5400, based on the second Hall signal and the at least two light-shielding signals, determine that the deadbolt lock has completed the locked reset.

[0223] In the process from the locked state to the locked reset state, the control unit 310 successively receives the light-shielding signal, the optical signal, and the light-shielding signal output by the second 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 lock is in the locked reset state based on the light-shielding signal, the optical signal, and the light-shielding signal output by the second photoelectric sensor 114, and the control unit 310 assists in determining that the deadbolt lock is in the locked reset state through the continuously received second Hall signal to verify the accuracy of the deadbolt lock being in the locked reset state.

[0224] In summary, when the user rotates the handle of the diagonal bolt lock, the rotation induction module can detect the rotation of the transmission shaft that rotates synchronously with the handle, generate an electrical signal, and the control unit synchronously controls the automatic unlocking of the deadbolt lock based on this electrical signal, so as to reduce the unlocking steps of the combination lock and improve the user experience.
