Description

Technical Field

[0001] The present invention belongs to the technical field of locks, and in particular relates to a combination lock. Background Art

[0002] In today's residential door lock market, the combination of deadbolt locks and latch bolt locks dominates. The original intention of this combination lock is to improve the safety of the door through a double locking mechanism and provide more reliable protection for the family living environment. However, in actual daily use, this seemingly safe combination brings many inconveniences to users, seriously affecting the convenience of opening the door and user experience.

[0003] When users need to open the door and go out, they must go through a series of complex and tedious operation processes. First, users need to use knobs, handles or keys to perform a separate unlocking operation on the deadbolt. This step seems simple, but it actually requires high operating accuracy from the user. In actual scenarios, unlocking failures may occur due to factors such as the rotation angle of the knob, the pressing force of the handle, or the insertion depth of the key. For example, the knob needs to be turned precisely to a specific angle to trigger the unlocking mechanism. If the user does not turn the angle enough or too much, the unlocking cannot be successful; when the handle is pressed, if the force is not enough, the retraction of the internal lock tongue may not be triggered, and excessive force may damage the handle or lock body; when the key is inserted, if it does not completely 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 he is in a hurry to go out.

[0004] After unlocking the deadbolt lock, the user cannot open the door directly, but needs to turn the handle of the deadbolt lock separately to unlock the deadbolt lock. The entire door opening process involves multiple operations, complicated steps, and takes a long time. For modern people who have a fast pace of daily life and precious time, this way of opening the door 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's experience. Moreover, in some emergency situations, such as fires, earthquakes and other disasters, this complicated way of opening the door may delay the escape time and pose a potential threat to the user's life safety. In addition, frequent and complicated operations can easily cause users to feel irritable and affect their daily mood.

[0005] Therefore, the existing combination locks using a deadbolt lock and a latch bolt lock have obvious deficiencies in the convenience of door opening, and a new door lock technology that can simplify the door opening operation and improve the door opening efficiency is urgently needed to solve the above problems. Summary of the invention

[0011] In one embodiment, the rotation sensing module includes an encoder, and the encoder is sleeved on the transmission shaft.

[0012] In one embodiment, the rotation sensing module includes a micro switch and a touch portion disposed on the transmission shaft, and the micro switch is disposed on a rotation path of the touch portion.

[0013] In one embodiment, the control unit is installed in the deadbolt lock, and the deadbolt lock is also provided with a first communication module electrically connected to the control unit, and the latch bolt lock is also provided with a second communication module electrically connected to the rotation sensing module, and the first communication module is wirelessly connected to the second communication module.

[0014] In one embodiment, the control unit is installed in the deadbolt, and the control unit is electrically connected to the rotation sensing module via a cable.

[0015] In one embodiment, the first transmission mechanism includes a lock core paddle, a rotating shaft, a toothed disc, a linkage block and a second photoelectric sensor, the lock core paddle is connected to the first lock tongue and the rotating shaft respectively, the linkage block is fixed on the rotating shaft, the toothed disc is sleeved on the rotating shaft, a transmission block and a plurality of light blocking sheets are provided on the toothed disc, the transmission block and the linkage block are arranged on the same rotation path, the second photoelectric sensor is arranged on the rotation path of the light blocking sheet, the plurality of light blocking sheets are arranged in sequence at intervals along the circumferential direction of the toothed disc, and the motor is transmission-connected to the toothed disc.

[0016] In one embodiment, the transmission block is extended along the circumferential direction of the toothed disc, a travel groove is provided on the toothed disc, the travel groove and the transmission block are arranged in sequence along the same extension path, and the two end faces of the transmission block constitute the two groove walls of the travel groove, and the linkage block is inserted in the travel groove.

[0017] In one embodiment, the transmission block and the travel groove are both arranged across 180°, and the toothed disc is provided with four light-blocking plates, which are evenly spaced in the circumferential direction of the toothed disc.

[0020] Compared with the prior art, the present invention has many advantages, including but not limited to:

[0021] To open a door with an existing combination lock, the user must first unlock the deadbolt lock, then unlock the latch bolt lock, and finally pull the handle to open the door. The entire process involves multiple steps. However, the present invention synchronizes the unlocking operation of the deadbolt lock with the unlocking operation of the latch bolt lock through the cooperation of the rotation sensing module and the control unit. 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 the signal, the control unit outputs a driving control signal to the motor of the deadbolt lock, and the driving motor drives the deadbolt lock to unlock. This means that when the user unlocks the latch bolt lock, the deadbolt lock is also automatically unlocked, and there is no need to perform additional unlocking operations on the deadbolt lock separately, thereby simplifying the original multi-step unlocking process into one step, significantly reducing the user's operating steps.

[0022] For the majority of users, especially the elderly, children or people with limited mobility, this simplified unlocking method is more friendly and convenient. Take the elderly as an example. They may easily make mistakes in multi-step operations due to memory loss, resulting in the inability to open the door smoothly. The present invention reduces the complexity of operation through automatic synchronous unlocking, reducing the risk of the elderly being unable to open the door due to operational errors. For children, due to height and strength limitations, it may be difficult to complete certain unlocking steps that require greater grip or precise movements. The present invention can unlock the entire combination lock with just a simple action of turning the handle, which is more in line with children's operating capabilities and habits. In addition, for people with limited mobility, reducing the operating steps means reducing the difficulty and physical exertion of opening the door, allowing them to use the combination lock more easily, thereby greatly improving the user experience.

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

[0050] The present invention provides a combination lock. When a user holds a handle of a latch bolt lock and turns the handle, a rotation sensing module detects the rotation of the handle to generate an electrical signal. A control unit controls the unlocking of the deadbolt lock based on the electrical signal, so that when the user unlocks the latch bolt lock, the deadbolt lock is automatically unlocked synchronously, thereby improving the unlocking efficiency of the combination lock and enhancing the user experience.

[0051] In an exemplary embodiment of the present invention, Figure 1 and Figure 2 , or, combined with Figure 3 and Figure 4The 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.

[0052] 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.

[0053] Combination Figure 5 The oblique bolt lock 200 includes a handle 210, a rotation sensing module 260, 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 transmission-connected, 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 rotation sensing module 260 is electrically connected to the control unit 310.

[0054] Specifically, the second transmission mechanism includes a transmission shaft 240, one end of which 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 substantially perpendicular to the transmission shaft 240. When the handle 210 is rotated, the handle 210 drives the transmission shaft 240 to rotate at the same time, 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 exits the second lock tongue groove, so as to achieve locking or unlocking of the oblique bolt lock 200.

[0055] The latch bolt lock 200 further includes a housing 270, the transmission shaft 240 traverses 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 relatively pivoted on the housing 270. The rotation sensing module 260 is installed in the housing 270. Since a portion 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.

[0056] When the handle 210 is in the initial position, the second locking tongue 230 of the latch bolt lock 200 extends into the second locking tongue 230 groove, so that the latch bolt lock 200 is in a locked state. When the handle 210 is in the unlocking position, the second locking tongue 230 of the latch bolt lock 200 withdraws from the second locking tongue 230 groove, so that the latch bolt lock 200 is in an unlocking state.

[0057] In a typical embodiment of the present invention, the oblique tongue lock 200 also includes a reset mechanism, which is installed in the shell 270 of the oblique 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 shell 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.

[0058] When the latch bolt lock 200 is in the locked state, the return torsion spring 271 is in the initial state, and when the return torsion spring 271 is in the initial state, the return torsion spring 271 does not store elastic tension or elastic retraction force; when the latch bolt lock 200 is in the unlocked state, the transmission shaft 240 pulls the return torsion spring 271 to extend, so that the return torsion spring 271 is in the stretched state, and the return torsion spring 271 accumulates elastic retraction force. When the user manipulates the handle 210 to complete the unlocking of the latch bolt lock 200, and the user no longer applies 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, and 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 lock tongue 230 to move, so that the handle 210 returns from the unlocked position to the initial position, and the second lock tongue 230 also returns from the unlocked state to the locked state. In other words, by providing the reset mechanism, the latch bolt lock 200 in the unlocked state can be automatically returned to the locked state.

[0059] When the user unlocks the combination lock 300, the user holds the handle 210 and applies force to the handle 210, so that the handle 210 rotates, and the handle 210 drives the transmission shaft 240 to rotate synchronously, and 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, and the control unit 310 generates a first drive control signal based on the electrical signal. The control unit 310 outputs the first drive control signal to the motor 115 of the deadbolt 100 to control the motor 115 to work, thereby controlling the movement of the first lock tongue 160 through the motor 115, so that the deadbolt 100 is unlocked.

[0060] Thus, when the user turns the handle 210 to unlock the latch bolt lock 200, the rotation sensing module 260 generates a corresponding electrical signal by detecting the rotation of the transmission shaft 240, and the control unit 310 generates a first drive control signal based on the received electrical signal. The control unit 310 controls the motor 115 to work through the first drive control signal, so as to drive the first bolt 160 to operate through the motor 115, so as to unlock the deadbolt lock 100. It can be understood that when the user turns the handle 210 to unlock the latch bolt lock 200, the deadbolt lock 100 is also unlocked synchronously, so that the user can unlock in one step without having to unlock the deadbolt lock 100 and the latch bolt lock 200 separately, so as to reduce the unlocking steps of the combination lock 300, improve the unlocking efficiency, and enhance the user's experience.

[0061] In the first embodiment, the combination Figure 6 The rotation sensing module 260 includes a Hall sensor (the Hall sensor is referred to as a first Hall sensor 261) and a magnet (the magnet is referred to as a 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.

[0062] When the latch bolt lock 200 is in an unlocked state, the first magnet 262 is in a magnet unlocking position; when the latch bolt lock 200 is in a locked state, the first magnet 262 is in a magnet locking position. The first Hall sensor 261 is disposed on the rotation path of the first magnet 262, and the first Hall sensor 261 is disposed close to the magnet locking position.

[0063] When the handle 210 drives the first magnet 262 to rotate synchronously through the transmission shaft 240, so that the first magnet 262 leaves the magnet locking position, the first Hall sensor 261 cannot sense the first magnet 262, thereby generating an electrical signal (the 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, and the control unit 310 determines that the latch bolt 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 deadbolt 100 to be unlocked synchronously, thereby improving the unlocking efficiency and the user experience.

[0064] When the reset mechanism synchronously drives the first magnet 262 to rotate via the transmission shaft 240, so that the first magnet 262 returns to the magnet locking position, the first Hall sensor 261 senses the first magnet 262, thereby generating an electrical signal (the electrical signal is referred to as a second electrical signal) accordingly. The first Hall sensor 261 outputs the second electrical signal to the control unit 310, and the control unit 310 determines that the latch bolt lock 200 is in the locked state based on the second electrical signal.

[0065] In another embodiment, the first Hall sensor 261 may be replaced by a reed switch sensor. For the specific matching relationship between the reed switch sensor and the first magnet 262 , please refer to the matching relationship between the first Hall sensor 261 and the first magnet 262 , which will not be repeated here to save space.

[0066] In the second embodiment, the combination Figure 7 The rotation sensing module 260 includes a shading sheet 264 and a photoelectric sensor (the photoelectric sensor is referred to as a first photoelectric sensor 263). The shading 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 shading sheet 264 to rotate synchronously.

[0067] When the latch bolt lock 200 is in the unlocked state, the light shielding sheet 264 is in the light shielding unlocking position; when the latch bolt lock 200 is in the locked state, the light shielding sheet 264 is in the light shielding 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 at the light shielding locking position.

[0068] When the handle 210 drives the shading sheet 264 to rotate synchronously through the transmission shaft 240, so that the shading sheet 264 leaves the shading locking position, the light emitted by the first photoelectric sensor 263 is no longer blocked by the shading sheet 264, thereby generating an electrical signal (the electrical signal is referred to as the first electrical signal). The first photoelectric sensor 263 outputs the first electrical signal to the control unit 310, and the control unit 310 determines that the latch bolt 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, and controls the motor to work through the first drive control signal, controls the deadbolt 100 to be unlocked synchronously, improves the unlocking efficiency, and improves the user experience.

[0069] When the reset mechanism drives the light shielding sheet 264 to rotate synchronously via the transmission shaft 240, so that the light shielding sheet 264 returns to the light shielding locked position, the light emitted by the first photoelectric sensor 263 is blocked by the light shielding sheet 264, thereby generating an electrical signal (the electrical signal is referred to as a second electrical signal) accordingly. The first photoelectric sensor 263 outputs the second electrical signal to the control unit 310, and the control unit 310 determines that the latch bolt lock 200 is in the locked state based on the second electrical signal.

[0070] In the third embodiment, combined 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.

[0071] When the latch bolt lock 200 is in an unlocked state, the encoder 265 is in a coded unlocking position; when the latch bolt lock 200 is in a locked state, the encoder 265 is in a coded locking position.

[0072] When the handle 210 drives the encoder 265 to rotate synchronously through the transmission shaft 240, so that the encoder 265 leaves the coded locking position, the encoder 265 generates an electrical signal (the electrical signal is called the first electrical signal) accordingly. The encoder 265 outputs the first electrical signal to the control unit 310, and the control unit 310 determines that the latch bolt 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, and controls the motor to work through the first drive control signal, controls the deadbolt lock 100 to be unlocked synchronously, improves the unlocking efficiency, and improves the user experience.

[0073] When the reset mechanism synchronously drives the encoder 265 to rotate via the transmission shaft 240, so that the encoder 265 returns to the coded locked position, the encoder 265 generates an electrical signal (the electrical signal is referred to as a second electrical signal) accordingly. The encoder 265 outputs the second electrical signal to the control unit 310, and the control unit 310 determines that the latch bolt lock 200 is in the locked state based on the second electrical signal.

[0074] In the fourth embodiment, combined with Fig. 9 The rotation sensing module 260 includes a micro switch 266 and a touch portion 267 disposed on the transmission shaft 240. The touch 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 touch portion 267 to rotate synchronously.

[0075] When the latch bolt lock 200 is in the unlocked state, the trigger portion 267 is in the trigger unlocked position; when the latch bolt lock 200 is in the locked state, the trigger portion 267 is in the trigger locked position. The micro switch 266 is disposed on the rotation path of the trigger portion 267, and the micro switch 266 is disposed close to the trigger locked position.

[0076] When the handle 210 drives the touch part 267 to rotate synchronously through the transmission shaft 240, so that the touch part 267 leaves the touch-lock position, the micro switch 266 can no longer be touched by the touch part 267, thereby generating an electrical signal (the electrical signal is called the first electrical signal) accordingly. The micro switch 266 outputs the first electrical signal to the control unit 310, and the control unit 310 determines that the latch bolt 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, and controls the motor to work through the first drive control signal, controls the deadbolt 100 to be unlocked synchronously, improves the unlocking efficiency, and improves the user experience.

[0077] When the reset mechanism drives the triggering part 267 to rotate synchronously through the transmission shaft 240, so that the triggering part 267 returns to the triggering locking position, the micro switch 266 is triggered by the triggering part 267, thereby generating an electrical signal (the electrical signal is referred to as a second electrical signal) accordingly. The micro switch 266 outputs the second electrical signal to the control unit 310, and the control unit 310 determines that the latch bolt lock 200 is in the locked state based on the second electrical signal.

[0078] Therefore, through the specific implementation of the first embodiment, the second embodiment, the third embodiment and the fourth embodiment, it can be known that the rotation sensing module 260 of the present invention has multiple implementation forms. After understanding the technical solution of the present invention, those skilled in the art can think of various deformations and improvements based on the technical concept of the present invention without paying creative labor, which should be regarded as falling within the protection scope defined by the present invention.

[0079] In an exemplary embodiment of the present invention, the 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 rotation sensing module 260 provided in the latch bolt lock 200 are connected by wire or wirelessly.

[0080] In one embodiment, in combination Figure 2 , the control unit 310 is wirelessly connected to the rotation sensing module 260. 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 rotation sensing module 260, and the first communication unit 170 and the second communication unit 250 are wirelessly connected. The control unit 310 and the rotation sensing module 260 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.

[0081] In another embodiment, in combination Figure 4 , the control unit 310 is connected to the rotation sensing module 260 by wire. Specifically, the control unit 310 is connected to the rotation sensing module 260 by a cable 320, so that good data interaction is achieved 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 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 wiring harness, but it should not be understood as a limitation to the present invention.

[0082] In an exemplary embodiment of the present invention, Fig.10 , Fig.11 and Fig.13The deadbolt 100 includes the first transmission mechanism and the first lock tongue 160. The first transmission mechanism includes the lock core paddle 150. 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.

[0083] The lock core paddle 150 is disposed perpendicularly to the first lock tongue 160, and the lock core paddle 150 is fixedly disposed to the first lock tongue 160. Fig.12 The lock core paddle 150 is a flat columnar structure, wherein the lock core paddle 150 includes an unlocking surface 151 and an upper locking surface 152 adjacent to each other, wherein the unlocking surface 151 is perpendicular to the upper locking surface 152, and the width of the unlocking surface 151 is greater than the width of the upper 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 lock tongue groove, the first lock tongue 160 withdraws from the first lock tongue groove to achieve unlocking; when the lock core paddle 150 is rotated so that the upper locking surface 152 of the lock core paddle 150 faces the first lock tongue groove, the first lock tongue 160 extends into the first lock tongue groove to achieve locking.

[0084] In an exemplary embodiment of the present invention, Fig.13 The first transmission mechanism further includes a rotating shaft 111, a toothed disc 120, a linkage block 113, a photoelectric sensor 114 (the photoelectric sensor is referred to as a 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 toothed disc 120 to rotate. Figure 2 The rotating shaft 111 is connected to the lock core paddle 150, and the Fig.16 , the linkage block 113 is arranged on the rotating shaft 111, the toothed disc 120 is provided with a gear hole, the toothed disc 120 is sleeved on the rotating shaft 111 through the gear hole, the gear hole is a round 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 toothed disc 120 cannot directly drive the rotating shaft 111 to rotate. Alternatively, the diameter of the gear hole is larger 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 toothed disc 120 cannot directly drive the rotating shaft 111 to rotate.

[0085] Combination Fig.14 and Fig.16The toothed disc 120 is provided with a transmission block 122, 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 arranged on the toothed disc 120 will move synchronously, because 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 the rotation process, so that the transmission block 122 will drive the rotating shaft 111 to rotate through the linkage block 113, and the rotating shaft 111 will drive the lock core paddle 150 to rotate, and the lock core paddle 150 will drive 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 that the deadbolt 100 is locked or unlocked.

[0086] Combination Fig.14 and Fig.15 The toothed disc 120 is provided with a plurality of light shielding sheets 130, and the toothed disc 120 will drive the light shielding sheets 130 to rotate synchronously, and the second photoelectric sensor 114 is arranged on the rotation path of the light shielding sheets 130. When the toothed disc 120 drives the light shielding sheets 130 to pass through the second photoelectric sensor 114, the light shielding sheets 130 will block the light emitted by the second photoelectric sensor 114, so that the second photoelectric sensor 114 generates a light shielding signal, and the second 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 determines the working state of the deadbolt 100.

[0087] In this embodiment, the toothed disc 120 is provided with a plurality of light blocking plates 130, and the plurality of light blocking plates 130 are evenly distributed in the circumferential direction of the toothed disc 120. For example, if two light blocking plates 130 are provided on the toothed disc 120, the two light blocking plates 130 are arranged at 180° to each other; if three light blocking plates 130 are provided on the toothed disc 120, the three light blocking plates 130 are arranged in sequence along the circumferential direction of the toothed disc 120, and the two adjacent light blocking plates 130 are arranged at 120° to each other.

[0088] 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°.

[0089] 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.

[0090] In this embodiment, combined with Fig.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.

[0091] 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.

[0092] Combination Fig.13 and Fig.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.

[0093] Combination Fig.14 and Fig.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.

[0094] 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.

[0095] In order to facilitate the description of the working principle of the deadbolt 100 of the present invention, Fig.18 and Fig.19 , Fig.18This is a plan view of the assembly of the rotating shaft, linkage ring, and second photoelectric sensor. Fig.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.

[0096] Combination Fig. 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.

[0097] Combination Fig. 20 and Fig.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.

[0098] Combination Fig.21 and Fig. 22When the deadbolt 100 is in the unlocked state, the control unit 310 controls the motor 115 to reverse, and the motor 115 drives the toothed disc 120 to rotate 180° clockwise, 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 disc 120 rotating 180° clockwise, the first end face 1222 and the second end face 1223 will not be linked with the linkage block 113, so that the toothed disc 120 will not drive the linkage ring 118, the rotating shaft 111, the lock core paddle 150 and the first lock tongue 160 to rotate through the linkage block 113. Furthermore, when the toothed disc 120 rotates 180° clockwise, the fourth light shielding sheet 134 will leave the second photoelectric sensor 114, so that the second photoelectric sensor 114 generates a photoelectric signal, and the first light shielding sheet 131 and the second light shielding sheet 132 sequentially pass the second photoelectric sensor 114, and the second photoelectric sensor 114 sequentially generates a light shielding signal, a photoelectric signal, and a light shielding signal based on the first light shielding sheet 131 and the second light shielding sheet 132, and the second light shielding sheet 132 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, and thus the control unit 310 correspondingly determines that the deadbolt 100 is in an unlocking and resetting state, and prepares for locking the deadbolt 100 later.

[0099] Combination Fig. 22 and Fig.23When the deadbolt 100 is in the unlocked reset state and needs to be locked, the control unit 310 outputs the driving 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 surface 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. Furthermore, when the toothed disc 120 rotates 90° clockwise, the second light shielding sheet 132 will leave the second photoelectric sensor 114, so that the second photoelectric sensor 114 generates a photoelectric signal; then the third light shielding sheet 133 will rotate 90° clockwise to the second photoelectric sensor 114, and the second photoelectric sensor 114 will generate a light shielding signal accordingly, and the third light shielding sheet 133 will stay 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, and thus the control unit 310 determines that the deadbolt 100 is in a locked state.

[0100] Combination Fig.23 and Fig. 20When the deadbolt 100 is in the locked state, the control unit 310 controls the motor 115 to rotate forward, and the motor 115 drives the toothed disc 120 to rotate 180° counterclockwise, so that the second end face 1223 of the transmission block 122 rotates 180° counterclockwise to separate from the linkage block 113, and the first end face 1222 of the transmission block 122 rotates 180° counterclockwise synchronously to abut against the linkage block 113. During the rotation process of the toothed disc 120, the first end face 1222 and the second end face 1223 will not be linked with the linkage block 113, so that the toothed disc 120 will not drive the linkage ring 118, the rotating shaft 111, the lock core paddle 150 and the first lock tongue 160 to rotate through the linkage block 113. Furthermore, when the toothed disc 120 rotates 180° counterclockwise, the third light shielding sheet 133 will leave the second photoelectric sensor 114, so that the second photoelectric sensor 114 generates a photoelectric signal, and the second light shielding sheet 132 and the first light shielding sheet 131 pass through the second photoelectric sensor 114 in sequence, and the second photoelectric sensor 114 generates a light shielding signal, a photoelectric signal and a light shielding signal in sequence based on the second light shielding sheet 132 and the first light shielding sheet 131, and the first light shielding sheet 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, and thus the control unit 310 determines that the deadbolt 100 is in a locked reset state, and prepares for the subsequent unlocking of the deadbolt 100.

[0101] Therefore, the above describes the whole process of the deadbolt 100 of the present invention from locked reset state-unlocked state-unlocked reset state-locked state-locked reset state. The deadbolt 100 can judge the state of the deadbolt 100 through the received photoelectric signal and the shading signal, so that the control unit 310 can accurately control the operation of the deadbolt 100 only through a single second photoelectric sensor 114, thereby reducing the number of sensors of the deadbolt 100 and reducing the production cost of the deadbolt 100.

[0102] In one embodiment, in combination Figures 15 to 18 The deadbolt 100 is further provided with a second Hall sensor (the Hall sensor is referred to as the second Hall sensor 141) and a magnet (the magnet is referred to as the second magnet 142). The second magnet 142 is provided 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 provided 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.

[0103] 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 90° to the first lock tongue groove. The second magnet 142 is disposed at 90° to the linkage block 113, and because the rotating shaft 111 and the lock core paddle 150 are fixedly disposed, and the rotating shaft 111 and the lock core paddle 150 rotate synchronously, the orientation of the second magnet 142 and the orientation of the upper locking surface 152 of the lock core paddle 150 are set to be the same.

[0104] Combination Fig. 20 and Fig.21 When the control unit 310 controls the motor 115 to work, the motor 115 drives the toothed disc 120 to rotate, and the toothed disc 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 100 is unlocked. At the same time, the locking surface 152 of the rotating shaft 111 faces the second Hall sensor 141, and the second magnet 142 is close to the second Hall sensor 141. The second Hall sensor 141 senses the second magnet 142 and generates a first Hall signal. When the control unit 310 receives the first Hall signal, it is determined that the deadbolt 100 is in an unlocked state.

[0105] Combination Fig. 22 and Fig.23 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 second magnet 142 is 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, and the control unit 310 receives the second Hall signal, and then determines that the deadbolt 100 is in a locked state.

[0106] Therefore, the deadbolt 100 of the present invention can use the second Hall sensor 141 to assist in determining whether the deadbolt 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 deadbolt 100.

[0107] In one embodiment, in combination Fig.10 , Fig.11 and Fig.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.

[0108] 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.

[0109] In a further embodiment, in combination Fig.10 , Fig.18 , Figure 20 to Figure 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.

[0110] In one embodiment, in combination Fig.13 and Fig.17The housing 143 is also provided with a bottom plate 1431, and the bottom plate 1431 is provided with a pivot hole 1432. The knob 144 is provided on the outer side of the bottom plate 1431. The shaft 111 passes through the pivot hole 1432 to be plugged with the knob 144, so that the knob 144 is relatively pivoted on the bottom plate 1431. Bearing grooves 1433 are formed on both sides of the bottom plate 1431, that is, the two bearing grooves 1433 are respectively provided on the inner side and the outer side of the bottom plate 1431, and the two bearing grooves 1433 are coaxially provided with the pivot hole 1432.

[0111] The two bearing grooves 1433 are both equipped with bearings 147, and the bearings 147 and the bearing grooves 1433 are tightly matched. The bearings 147 are sleeved on the rotating shaft, and the bearings 147 and the rotating shaft 111 are also tightly matched. Since the two bearings 147 are tightly matched with the bearing grooves 1433 and the rotating shaft, respectively, the rotating shaft 111 and the pivot hole 1432 are also tightly matched, which solves the problem of the rotating shaft 111 shaking during the rotation process. 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 enhanced after the knob 144 is rotated under force, which avoids affecting the rotation feel of the knob 144 and increasing the driving resistance of the motor, thereby improving the user experience.

[0112] In one embodiment, in combination Fig.13 and Fig.15 The deadbolt 100 is further provided with a circuit board 146 . The circuit board 146 is installed in the housing 143 . The second photoelectric sensor 114 and the second Hall sensor 141 are both integrated on the circuit board 146 .

[0113] To sum up, when the user turns the handle of the latch bolt lock, the rotation sensing module can detect the rotation of the transmission shaft that rotates synchronously with the handle and generate an electrical signal. The control unit synchronously controls the deadbolt lock to automatically unlock based on the electrical signal, thereby reducing the unlocking steps of the combination lock and improving the user experience.
