Description

Technical Field

[0001] This utility model belongs to the field of lock technology, and specifically relates to a combination lock. Background Technology

[0002] In today's residential door lock market, the combination of a deadbolt and a latch lock dominates the market. The original design intention of this combination lock was to enhance door security through a dual locking mechanism, providing more reliable protection for the home environment. However, in actual daily use, this seemingly secure combination has brought many inconveniences to users, seriously affecting the ease of opening the door and the user experience.

[0003] When users need to unlock the door to leave, they must go through a series of complex and cumbersome procedures. First, users need to use a knob, handle, or key to unlock the lock individually. This step seems simple, but in reality, it requires a high degree of precision from the user. In actual scenarios, factors such as the rotation angle of the knob, the pressure applied to the handle, or the insertion depth of the key can all lead to unlocking failure. For example, the knob needs to be turned precisely to a specific angle to trigger the unlocking mechanism; if the user turns it too little or too much, it will not unlock successfully. When pressing the handle, insufficient force may not trigger the retraction of the internal bolt, while excessive force may damage the handle or the lock body. When inserting the key, if it does not fully engage with the lock cylinder's teeth, it will also prevent the key from turning. If the operation is incorrect, the user needs to try repeatedly, which not only wastes time but may also cause anxiety and frustration when the user is in a hurry to leave.

[0004] After unlocking the deadbolt, the user cannot open the door directly; they must separately turn the handle of the latch lock to unlock it. The entire opening process involves multiple operations, is complex, and time-consuming. For modern people with fast-paced lives and precious time, this method is clearly inconvenient, especially when they urgently need to leave. The existing combination lock opening method significantly impacts user efficiency and reduces the user experience. Furthermore, in emergencies such as fires or earthquakes, this complex opening method may delay escape time, posing a potential threat to the user's life. In addition, frequent and complex operations can easily lead to user frustration and affect their daily mood.

[0005] Therefore, existing combination locks that use a combination of deadbolt and latch bolt have significant shortcomings in terms of ease of opening, and there is an urgent need for a new type of door lock technology that can simplify the opening operation and improve the opening efficiency to solve the above problems. Utility Model Content

[0006] The primary objective of this invention is to provide a combination lock that solves at least one of the aforementioned problems.

[0007] To achieve the various objectives of this utility model, the following technical solution is adopted:

[0008] To achieve one of the objectives of this utility model, a combination lock is provided, comprising a control unit and a separately configured deadbolt and latch lock. The deadbolt includes a motor, a first transmission mechanism, and a first latch. The motor is used to respond to a drive control signal and drive the first transmission mechanism to extend and retract the first latch. The latch lock is provided with a handle, a second transmission mechanism, a second latch, and a touch module. The handle is configured to rotatably drive the second transmission mechanism to extend and retract the second latch. The control unit is used to receive a target electrical signal output by the touch module and output the drive control signal to the motor based on the target electrical signal. The touch module includes a touch control for triggering the target electrical signal, and the touch control is exposed on the handle.

[0009] In one embodiment, the touch module is a fingerprint verification module, which includes a fingerprint verification unit electrically connected to the touch control, and the touch control is a fingerprint acquisition device.

[0010] In one embodiment, the touch module is a switch module, the switch module includes a switch circuit, the switch circuit is electrically connected to the touch control, and the touch control is a push switch.

[0011] In one embodiment, the handle includes a vertical bar and a horizontal bar, the second transmission mechanism includes a transmission shaft, the two ends of which are respectively connected to the second latch and the vertical bar, and the touch module is disposed on the horizontal bar.

[0012] In one embodiment, the control unit is installed in the deadbolt, the deadbolt is further provided with a first communication module electrically connected to the control unit, and the latch lock is further provided with a second communication module electrically connected to the touch module, the first communication module and the second communication module being electrically connected.

[0013] In one embodiment, the control unit is installed in the lock, and the control unit and the touch module are electrically connected via a cable.

[0014] In one embodiment, the first transmission mechanism includes a lock cylinder lever, a rotating shaft, a gear disc, a linkage block, and a photoelectric sensor. The lock cylinder lever is connected to the first lock tongue and the rotating shaft respectively. The linkage block is fixed on the rotating shaft. The gear disc is sleeved on the rotating shaft. The gear disc is provided with a transmission block and a plurality of light-blocking plates. The transmission block and the linkage block are arranged on the same rotation path. The photoelectric sensor is arranged on the rotation path of the light-blocking plates. The plurality of light-blocking plates are arranged sequentially at intervals along the circumference of the gear disc. The motor is connected to the gear disc in a transmission connection.

[0015] In one embodiment, the transmission block extends along the circumferential direction of the gear disk, the gear disk is provided with a stroke groove, the stroke groove and the transmission block are arranged sequentially along the same extension path, and the two end faces of the transmission block form the two groove walls of the stroke groove, and the linkage block is inserted into the stroke groove.

[0016] In one embodiment, the transmission block and the stroke groove are both arranged across 180°, and the gear disk is provided with four light-blocking plates, which are evenly spaced in the circumferential direction of the gear disk.

[0017] In one embodiment, the deadbolt further includes a Hall sensor and a magnet, the magnet being disposed on the rotating shaft and the Hall sensor being disposed on the rotation path of the magnet.

[0018] Compared with the prior art, this utility model has many advantages, including but not limited to:

[0019] In existing technologies, users need to unlock the deadbolt and latch lock separately, which is cumbersome and time-consuming. This invention, however, by incorporating a touch module on the latch lock and connecting it to a control unit, allows the control unit to automatically control the deadbolt motor based on signals from the touch module when the user unlocks the latch lock. This drives the first transmission mechanism to retract the first latch, achieving synchronous automatic unlocking of the deadbolt. This simplifies the unlocking process, which previously required two or more steps, into a single operation, significantly reducing the time required for the user to open the door and substantially improving the unlocking efficiency of combination locks.

[0020] For users, cumbersome door-opening procedures often lead to inconvenience and frustration, especially in emergencies where the complexity of the operation may delay the opening opportunity. This utility model's combination lock simplifies the door-opening process, reducing potential user errors and allowing for easier and faster door opening, thus significantly improving the user experience and product satisfaction. Furthermore, this simplified opening method is more user-friendly for the elderly, children, or people with mobility issues, reducing barriers to use caused by operational difficulties.

[0041] It will be understood by those skilled in the art that, unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. It should also be understood that terms such as those defined in general dictionaries should be understood to have the same meaning as in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless specifically defined as herein.

[0042] This utility model provides a combination lock. When unlocking the latch lock, the user can simultaneously and automatically unlock the deadbolt lock by touching the touch module on the latch lock of the combination lock. This eliminates the need for the user to unlock the deadbolt lock and the latch lock separately, thereby improving the unlocking efficiency of the combination lock and enhancing the user experience.

[0043] In a typical embodiment of this utility model, combined with Figure 1 and Figure 2 ,or Figure 3 The combination lock 300 includes a control unit 310, a deadbolt 100, and a latch bolt 200, with the deadbolt 100 and the latch bolt 200 being separately configured. The combination lock 300 is installed on a door body 400, which is installed on a door frame. The door frame has two latch grooves, namely a first latch groove and a second latch groove. The first latch groove corresponds to the deadbolt 100, and the second latch groove corresponds to the latch bolt 200.

[0044] The deadbolt 100 includes a motor 115, a transmission mechanism (referred to as the first transmission mechanism), and a latch (referred to as the first latch 160). The motor 115, the first transmission mechanism, and the first latch 160 are sequentially connected. The motor 115 drives the first latch 160 to extend into the first latch groove via the first transmission mechanism to lock the deadbolt 100. Alternatively, the motor 115 drives the first latch 160 to retract from the first latch groove via the first transmission mechanism to unlock the deadbolt 100. The control unit 310 is used to control the operation of the motor 115.

[0045] The latch lock 200 includes a handle 210, a touch module 220, a transmission mechanism (referred to as the second transmission mechanism), and a latch (referred to as the second latch 230). The handle 210, the second transmission mechanism, and the second latch 230 are sequentially connected. The handle 210, via the second transmission mechanism, drives the second latch 230 into the second latch groove to lock the latch lock 200; alternatively, the handle 210, via the second transmission mechanism, drives the second latch 230 out of the second latch groove to unlock the latch lock 200. The touch module 220 is electrically connected to the control unit 310.

[0046] Specifically, in combination Figure 1 , Figure 3 and Figure 4The second transmission mechanism includes a transmission shaft 240, one end of which is inserted into the handle 210. The transmission shaft 240 is connected to the second latch 230, and the second latch 230 is arranged approximately perpendicular to the transmission shaft 240. When the handle 210 is rotated, the handle 210 drives the transmission shaft 240 to rotate simultaneously. The transmission shaft 240 drives the second latch 230 to move linearly relative to the second latch groove, causing the second latch 230 to extend into or retract from the second latch groove, thereby locking or unlocking the latch lock 200.

[0047] The touch module 220 is disposed on the handle 210 and is electrically connected to the control unit 310. The touch module 220 includes a touch control 221 and a detection unit 222. The detection unit 222 is disposed inside the handle 210, and the touch control 221 is disposed on the side of the handle 210 so that the touch control 221 is exposed on the handle 210.

[0048] Combination Figure 2 When a user locks or unlocks the combination lock 300, the user's hand grips the handle 210, and the user's hand touches the touch control 221 exposed on the handle 210. The detection unit 222 responds to the touch event of the touch control 221 and generates a target electrical signal. The detection unit 222 outputs the target electrical signal to the control unit 310. The control unit 310 generates a drive control signal based on the target electrical signal and outputs the drive control signal to the motor 115 of the deadbolt 100 to control the operation of the motor 115. The motor 115 then controls the movement of the first bolt 160, thereby unlocking or locking the deadbolt 100.

[0049] Therefore, when the user turns the handle 210 to unlock the latch lock 200, the user touches the touch module 220, which generates a corresponding target electrical signal. The control unit 310 generates a drive control signal based on the received target electrical signal. The control unit 310 controls the motor 115 to operate, thereby driving the first latch 160 to unlock the deadbolt 100. It can be understood that when the user turns the handle 210 to unlock the latch lock 200, the deadbolt 100 also unlocks simultaneously, allowing for one-step unlocking without needing to unlock the deadbolt 100 and the latch lock 200 separately. This reduces the unlocking steps of the combination lock 300, improves unlocking efficiency, and enhances the user experience.

[0050] In one embodiment, combined Figure 1 and Figure 2 ,or Figure 3 The touch module 220 is a switch module, the touch control 221 of the touch module 220 is a push switch, and the detection unit 222 is a switch circuit. When the user holds the handle 210, he / she can press the push switch to cause the switch circuit to generate a corresponding target electrical signal. In this embodiment, when the combination lock 300 needs to be unlocked, the user holds the handle 210 and presses the push switch to control the deadbolt 100 to unlock. The user also rotates the handle 210 simultaneously to unlock the latch lock 200. This allows the deadbolt 100 and the latch lock 200 of the combination lock 300 to unlock simultaneously, improving unlocking efficiency and enhancing the user experience.

[0051] In another embodiment, the touch module 220 is a fingerprint verification module, the touch control 221 of the touch module 220 is a fingerprint acquisition device, and the detection unit 222 is a fingerprint verification unit. When a user holds the handle 210, one of the user's fingers touches the fingerprint acquisition device. The fingerprint acquisition device responds to the user's operation event by generating an electrical signal, which carries user feature data, including the user's fingerprint data. The fingerprint acquisition device outputs the acquired electrical signal to the fingerprint verification unit.

[0052] After receiving the electrical signal output by the fingerprint acquisition device, the fingerprint verification unit parses the corresponding user feature data from the electrical signal. The fingerprint verification unit has a pre-set identity database containing user feature data of legitimate users. The fingerprint verification unit compares the user feature data with each user feature data in the identity database. When the acquired user feature data matches one of the user feature data in the identity database, the fingerprint verification unit sets the corresponding electrical signal as the target electrical signal; conversely, when the acquired user feature data does not match one of the user feature data in the identity database, the fingerprint verification unit sets the corresponding electrical signal as an invalid electrical signal. The fingerprint verification unit outputs the acquired target electrical signal to the control unit 310, and the control unit 310 controls the deadbolt 100 to unlock or lock based on the target electrical signal.

[0053] In this embodiment, when the combination lock 300 needs to be unlocked, the user holds the handle 210 and touches the fingerprint sensor with one finger. The fingerprint sensor generates an electrical signal, and the fingerprint verification unit determines whether the signal is the target signal based on the signal. If so, the target signal is output to the control unit 310, which controls the deadbolt 100 to unlock. Simultaneously, the user rotates the handle 210 to unlock the latch 200, thereby enabling the deadbolt 100 and the latch 200 of the combination lock 300 to unlock synchronously, improving unlocking efficiency and enhancing the user experience.

[0054] In one embodiment, combined Figure 3 and Figure 4 The handle 210 includes a vertical bar 211 and a horizontal bar 212. The vertical bar 211 and the horizontal bar 212 are connected and are arranged approximately perpendicularly to each other. One end of the drive shaft 240 is inserted into the vertical bar 211. The touch control 221 of the touch module 220 is disposed on the horizontal bar 212 and is exposed on the horizontal bar 212. Since the user mainly holds the horizontal bar 212 when holding the handle 210, the placement of the touch control 221 on the horizontal bar 212 makes it easier for the user to touch the touch control 221, thus improving the user experience.

[0055] In this embodiment, the door 400 includes a front 420 and a back 410. The crossbar 212 faces the back 410 of the door 400 and is positioned close to the back 410. The crossbar 212 has two sides, which are approximately parallel to the door 400. One side (referred to as the inner side, not shown) faces the back 410, and the other side (referred to as the outer side 2121) faces the same direction as the back 410, but is further away from the back 410 than the inner side. The touch control 221 is exposed on the outer side 2121 for easy observation by the user. Furthermore, the placement of the touch control 221 on the outer side 2121 is ergonomic, facilitating touch operation when the user is holding the handle 210.

[0056] In a further embodiment, the touch control 221 is exposed on the outer side 2121 and is positioned close to the vertical bar 211 to further facilitate the user's touch control 221 when holding the handle 210.

[0057] In a typical embodiment of this utility model, combined with Figure 1 and Figure 2 ,or, Figure 3 and Figure 4The control unit 310 is installed in the deadbolt 100. Since the deadbolt 100 and the latch 200 are separate units, the control unit 310 installed in the deadbolt 100 and the touch module 220 installed in the latch 200 are connected by wire or wireless means.

[0058] In one embodiment, combined Figure 1 and Figure 2 The control unit 310 is wirelessly connected to the touch module 220. Specifically, the deadbolt 100 also includes a first communication unit 170, which is electrically connected to the control unit 310; the latch lock 200 includes a second communication unit 250, which is electrically connected to the touch module 220. The first communication unit 170 and the second communication unit 250 are wirelessly connected. The control unit 310 and the touch module 220 communicate 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 be near-field communication devices to achieve good data communication at close range. For example, both the first communication unit 170 and the second communication unit 250 may be radio frequency devices, but this should not be construed as a limitation of the present invention.

[0059] In another embodiment, combined Figure 3 and Figure 4 The control unit 310 and the touch module 220 are connected by a wire. Specifically, the control unit 310 and the touch module 220 are connected by a cable 320 to enable good data interaction between them. In this embodiment, the cable 320 can be arranged within the door body 400 to avoid interference from the external environment and extend its service life. In this embodiment, it is recommended that the cable 320 be an electronic wire harness, but this should not be construed as a limitation of the present invention.

[0060] In a typical embodiment of this utility model, the deadbolt 100 includes the first transmission mechanism and the first bolt 160. The first transmission mechanism includes the lock cylinder lever 150. One end of the lock cylinder lever 150 is connected to the lock cylinder of the deadbolt 100. The lock cylinder lever 150 is connected to the first bolt 160. The lock cylinder lever 150 drives the first bolt 160 to move linearly along the extension direction of the first bolt 160, so that the first bolt 160 extends into or exits from the first bolt groove, thereby realizing the locking or unlocking of the deadbolt 100.

[0061] The lock cylinder lever 150 is perpendicular to the first lock tongue 160, and the lock cylinder lever 150 is fixed to the first lock tongue 160. (Combined) Figure 7 The lock cylinder lever 150 has a flat cylindrical structure, comprising an adjacent unlocking surface 151 and a locking surface 152. The unlocking surface 151 is perpendicular to the locking surface 152, and the width of the unlocking surface 151 is greater than the width of the locking surface 152. When the lock cylinder lever 150 is rotated so that the unlocking surface 151 faces the first bolt groove, the first bolt 160 retracts from the first bolt groove, thus unlocking. When the lock cylinder lever 150 is rotated so that the locking surface 152 faces the first bolt groove, the first bolt 160 extends into the first bolt groove, thus locking.

[0062] In a typical embodiment of this utility model, combined with Figure 8 The first transmission mechanism further includes a rotating shaft 111, a gear disk 120, a linkage block 113, a photoelectric sensor 114, and a motor 115. The control unit 310 is electrically connected to the photoelectric sensor 114 and the motor 115, respectively. The motor 115 is used to drive the gear disk 120 to rotate. Figure 6 The rotating shaft 111 is connected to the lock cylinder lever 150, and in combination Figure 11 The linkage block 113 is disposed on the rotating shaft 111. The gear disk 120 has a gear hole, and the gear disk 120 is sleeved on the rotating shaft 111 through the gear hole. The gear hole is a circular hole, and the section of the rotating shaft 111 corresponding to the gear hole has a cylindrical structure. This ensures that the gear hole, when sleeved on the rotating shaft 111, prevents the gear disk 120 from directly driving 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 engagement between the gear hole and the rotating shaft 111, thus preventing the gear disk 120 from directly driving the rotating shaft 111 to rotate.

[0063] Combination Figure 9 and Figure 11The gear disk 120 is provided with a transmission block 122, which is arranged on the same rotation path as the linkage block 113 on the rotating shaft 111. When the motor 115 drives the gear disk 120 to rotate, the transmission block 122 on the gear disk 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 via the linkage block 113. The rotating shaft 111 will drive the lock cylinder lever 150 to rotate, and the lock cylinder lever 150 will drive the first lock tongue 160 to move linearly, so that the first lock tongue 160 extends into or retracts from the first lock tongue groove, thereby locking or unlocking the deadbolt 100.

[0064] Combination Figure 9 and Figure 10 The gear disk 120 is provided with multiple light-blocking plates 130. The gear disk 120 will drive the light-blocking plates 130 to rotate synchronously. The photoelectric sensor 114 is disposed on the rotation path of the light-blocking plates 130. When the gear disk 120 drives the light-blocking plates 130 past the photoelectric sensor 114, the light-blocking plates 130 will block the light emitted by the photoelectric sensor 114, causing the photoelectric sensor 114 to generate a light-blocking signal. The photoelectric sensor 114 outputs the light-blocking signal to the control unit 310. Based on the light-blocking signal, the control unit 310 obtains the rotation angle of the gear disk 120 and determines the working state of the deadbolt 100.

[0065] In this embodiment, the toothed disk 120 is provided with a plurality of light-blocking plates 130, which are evenly distributed in the circumferential direction of the toothed disk 120. For example, if the toothed disk 120 is provided with two light-blocking plates 130, the two light-blocking plates 130 are arranged at 180° to each other; if the toothed disk 120 is provided with three light-blocking plates 130, the three light-blocking plates 130 are arranged sequentially along the circumferential direction of the toothed disk 120, and adjacent light-blocking plates 130 are arranged at 120° to each other.

[0066] In this embodiment, the present invention is described using the example of four light-blocking plates 130 on the gear disk 120, but this should not be construed as a limitation of the present invention. Specifically, the four light-blocking plates 130 are arranged sequentially along the circumference of the gear disk 120, with adjacent light-blocking plates 130 at 90° intervals. When the motor 115 drives the gear disk 120 to rotate, the gear disk 120 will drive the four light-blocking plates 130 to rotate synchronously. Assuming that when the gear disk 120 is not rotating, the angle at which the photoelectric sensor 114 is blocked by one of the light-blocking plates 130 is 0°; when the motor 115 drives the gear disk 120 to rotate, and the photoelectric sensor 114 is blocked by another light-blocking plate 130, the control unit 310 receives the light-blocking signal output by the photoelectric sensor 114, and the control unit 310 determines that the gear disk 120 has rotated 90°.

[0067] The control unit 310 outputs a drive control signal to the motor 115 to control the forward and reverse rotation of the motor 115, thereby controlling the rotation direction of the gear 120. The control unit 310 controls the rotation of the lock cylinder lever 150 by controlling the rotation of the gear 120, which in turn controls the insertion or withdrawal of the first bolt 160 into the first bolt groove, thus controlling the locking or unlocking of the deadbolt 100. Furthermore, the control unit 310 monitors the rotation angle of the gear 120 using a photoelectric sensor 114 to prevent the rotation angle of the gear 120 from being too large or too small, ensuring that the deadbolt 100 accurately locks or unlocks.

[0068] In this embodiment, combined with Figure 9 The transmission block 122 extends along the circumferential direction of the gear disk 120, such that its two end faces 1221 along the circumferential direction are angled. One of these end faces 1221 can abut against the linkage block 113 on the rotating shaft 111, thereby driving the rotating shaft 111 to rotate via the linkage block 113. Specifically, when the control unit 310 controls the motor 115 to rotate forward, one end face 1221 abuts against the linkage block 113; when the control unit 310 controls the motor 115 to rotate in reverse, the other end face 1221 abuts against the linkage block 113. This improves the rotation efficiency of the gear disk 120. In this invention, it is recommended that the transmission block 122 be arranged across 180°, that is, that the two end faces 1221 are arranged at 180°, so that when the motor 115 rotates forward or in reverse, the rotation angle of the transmission block 122 can be reduced, allowing it to quickly abut against the linkage block 113.

[0069] In a typical embodiment of this utility model, the gear disk 120 is provided with a travel groove 121, which extends along the circumferential direction of the gear disk 120. The travel groove 121 and the transmission block 122 extend along the same path, and are connected end-to-end to form a ring structure. Furthermore, the two end faces 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 utility model is described using the example of the transmission block 122 spanning 180° along the circumferential direction and the travel groove 121 also spanning 180° along the circumferential direction, but this should not be construed as a limitation of the present utility model.

[0070] Combination Figure 8 and Figure 11 The first transmission mechanism is further provided with a linkage ring 118, which is sleeved on the rotating shaft 111 and fixedly disposed therebetween. A linkage block 113 is fixedly disposed on the linkage ring 118; in other words, the linkage block 113 is fixedly disposed 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 be integrally formed, but this should not be construed as a limitation of the present invention.

[0071] Combination Figure 9 and Figure 11 The gear disk 120 is provided with an annular groove 123, which is located inside the stroke groove 121, that is, the annular groove 123 is closer to the gear hole of the gear disk 120 than the stroke groove 121. The annular groove 123 is connected to the stroke 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 stroke groove 121 to limit the linkage block 113 through the stroke groove 121. The two end faces 1221 of the transmission block 122 can be selectively abutted against the linkage block 113.

[0072] When the gear disk 120 rotates, one end face 1221 of the transmission block 122 abuts against the linkage block 113. The gear disk 120 rotates further to drive the linkage block 113 to rotate through the corresponding end face 1221. The linkage block 113 then drives the rotating shaft 111 and the lock cylinder lever 150 to rotate in sequence, which in turn drives the first lock tongue 160 to move linearly, so as to realize that the first lock tongue 160 extends into or retracts from the first lock tongue groove, thereby realizing the locking or unlocking of the deadbolt 100.

[0073] To facilitate the description of the working principle of the deadbolt 100 of this utility model, combined with Figure 12 and Figure 13 , Figure 12This is a planar schematic diagram of the assembly of the rotating shaft, linkage ring, and photoelectric sensor. Figure 13 This is a planar schematic diagram of the gear disk 120. Let the four light-blocking plates 130 on the gear disk 120 be 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 in sequence along the circumferential direction of the gear disk 120. Let the two end faces 1221 of the transmission block 122 be the first end face 1222 and the second end face 1223, respectively.

[0074] Combination Figure 14 Assuming the deadbolt 100 is in the locked-reset state, the first light-blocking plate 131 is located at the photoelectric sensor 114. The photoelectric sensor 114 generates a light-blocking signal, and the control unit 310 determines that the deadbolt 100 is in the locked-reset state based on the light-blocking signal. Furthermore, the first end face 1222 abuts against the linkage block 113 of the linkage ring 118.

[0075] Combination Figure 14 and Figure 15 When the lock 100 needs to be unlocked, the control unit 310 outputs the drive control signal to the motor 115, controlling the motor 115 to rotate forward. The motor 115 drives the gear 120 to rotate counterclockwise by 90°. The first end face 1222 on the transmission block 122 drives the linkage ring 118 to rotate counterclockwise by 90° via the linkage block 113. During this process, the first light-blocking plate 131 on the gear 120 will move away from the photoelectric sensor 114. The photoelectric sensor 114 will no longer generate a light-blocking signal, but instead generates a photoelectric signal. After receiving the photoelectric signal, the control unit 310 determines that the first light-blocking plate 131 has moved away from the photoelectric sensor 114. Simultaneously, the fourth light-blocking plate 134 on the gear disc 120 will rotate 90° counterclockwise to the photoelectric sensor 114. The fourth light-blocking plate 134 will block the light emitted by the photoelectric sensor 114, generating a light-blocking signal again. The control unit 310 receives the light-blocking signal, determines that the fourth light-blocking plate 134 has rotated to the photoelectric sensor 114, and determines that the deadbolt 100 has been unlocked. At the same time, the first end face 1222 on the gear disc 120 also drives the linkage ring 118, the rotating shaft 111, the lock cylinder lever 150, and the first lock tongue 160 to rotate, causing the first lock tongue 160 to retract relative to the first lock tongue groove, thereby completing the unlocking and putting the deadbolt 100 in the unlocked state.

[0076] Combination Figure 15 and Figure 16When the lock 100 is in the unlocked state, the control unit 310 controls the motor 115 to reverse. The motor 115 drives the gear 120 to rotate 180° clockwise, causing the first end face 1222 of the transmission block 122 to rotate 180° clockwise to separate from the linkage block 113. Simultaneously, the second end face 1223 of the transmission block 122 rotates 180° clockwise and abuts against the linkage block 113. During the 180° clockwise rotation of the gear 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 120 will not drive the linkage ring 118, the rotating shaft 111, the lock cylinder lever 150, and the first lock tongue 160 to rotate via the linkage block 113. Furthermore, during the 180° clockwise rotation of the gear disk 120, the fourth light-blocking plate 134 will move away from the photoelectric sensor 114, causing the photoelectric sensor 114 to generate a photoelectric signal. The first light-blocking plate 131 and the second light-blocking plate 132 sequentially pass by the photoelectric sensor 114. Based on the first light-blocking plate 131 and the second light-blocking plate 132, the photoelectric sensor 114 sequentially generates a light-blocking signal, a photoelectric signal, and a light-blocking signal, with the second light-blocking plate 132 remaining at the photoelectric sensor 114. The control unit 310 sequentially receives the photoelectric signal and the light-blocking signal output by the photoelectric sensor 114. Therefore, the control unit 310 determines that the deadbolt 100 is in an unlocked reset state, preparing for the subsequent locking of the deadbolt 100.

[0077] Combination Figure 16 and Figure 17When the deadlock 100 is in the unlocked reset state and 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 plate 120 to rotate 90° clockwise, so that the second end face 1223 of the transmission block 122 drives the abutting linkage block 113 to rotate 90° clockwise. The linkage block 113 drives the linkage ring 118, the rotating shaft 111, the lock cylinder paddle 150 and the first lock tongue 160 to move synchronously, so that the first lock tongue 160 extends out relative to the first lock tongue groove and inserts into the first lock tongue groove, thereby making the deadlock 100 locked. Furthermore, during the 90° clockwise rotation of the gear disk 120, the second light-blocking plate 132 will move away from the photoelectric sensor 114, causing the photoelectric sensor 114 to generate a photoelectric signal; subsequently, the third light-blocking plate 133 will rotate 90° clockwise to the photoelectric sensor 114, and the photoelectric sensor 114 will correspondingly generate a light-blocking signal, with the third light-blocking plate 133 remaining at the photoelectric sensor 114. The control unit 310 sequentially receives the photoelectric signal and the light-blocking signal output by the photoelectric sensor 114, thereby determining that the deadbolt 100 is in a locked state.

[0078] Combination Figure 17 and Figure 14When the lock 100 is in the locked state, the control unit 310 controls the motor 115 to rotate forward. The motor 115 drives the gear 120 to rotate counterclockwise by 180°, causing the second end face 1223 of the transmission block 122 to rotate counterclockwise by 180° to separate from the linkage block 113. Simultaneously, the first end face 1222 of the transmission block 122 rotates counterclockwise by 180° to abut against the linkage block 113. During the rotation of the gear 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 120 will not drive the linkage ring 118, the rotating shaft 111, the lock cylinder lever 150, and the first lock tongue 160 to rotate via the linkage block 113. Furthermore, during the counterclockwise 180° rotation of the gear disk 120, the third light-blocking plate 133 will move away from the photoelectric sensor 114, causing the photoelectric sensor 114 to generate a photoelectric signal. The second light-blocking plate 132 and the first light-blocking plate 131 then pass by the photoelectric sensor 114 in sequence. Based on the second light-blocking plate 132 and the first light-blocking plate 131, the photoelectric sensor 114 sequentially generates a light-blocking signal, a photoelectric signal, and a light-blocking signal, while the first light-blocking plate 131 remains at the photoelectric sensor 114. The control unit 310 sequentially receives the photoelectric signal and the light-blocking signal output by the photoelectric sensor 114. Therefore, the control unit 310 determines that the deadbolt 100 is in a locked reset state, preparing for the subsequent unlocking of the deadbolt 100.

[0079] Therefore, the above describes the entire process of the lock 100 of this utility model from the locked reset state - unlocked state - unlocked reset state - locked state - locked reset state. The lock 100 can determine its state by receiving photoelectric signals and light-blocking signals, so that the control unit 310 can accurately control the operation of the lock 100 with only a single photoelectric sensor 114, reducing the number of sensors in the lock 100 and reducing the production cost of the lock 100.

[0080] In one embodiment, combined Figure 10 , Figure 11 and Figure 12 The first transmission mechanism is further equipped with a Hall sensor 141 and a magnet 142. The magnet 142 is mounted on the rotating shaft 111. When the rotating shaft 111 rotates, it will drive the magnet 142 to rotate synchronously. The Hall sensor 141 is located on the rotation path of the magnet 142. When the magnet 142 approaches the Hall sensor 141, the Hall sensor 141 will generate a Hall signal.

[0081] In this embodiment, the Hall sensor 141 is arranged adjacent to the photoelectric sensor 114, and the Hall sensor 141 is positioned at a 90° angle to the first locking tongue groove. The magnet 142 is positioned at a 90° angle to the linkage block 113. Because the rotating shaft 111 and the lock cylinder lever 150 are fixed together, and the rotating shaft 111 and the lock cylinder lever 150 rotate synchronously, the orientation of the magnet 142 and the orientation of the upper locking surface 152 of the lock cylinder lever 150 are set to be the same.

[0082] Combination Figure 14 and Figure 15 When the control unit 310 controls the motor 115 to operate, the motor 115 drives the gear 120 to rotate, and the gear 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 retracts from the first locking tongue groove, thus unlocking the deadbolt 100. At the same time, the locking surface 152 of the rotating shaft 111 faces the Hall sensor 141, and the magnet 142 approaches the Hall sensor 141. The Hall sensor 141 senses the magnet 142 and generates a first Hall signal. When the control unit 310 receives the first Hall signal, it determines that the deadbolt 100 is in the unlocked state.

[0083] Combination Figure 16 and Figure 17 When the control unit 310 controls the motor 115 to operate, the motor 115 drives the first latch 160 via the gear plate 120, the rotating shaft 111, and the lock cylinder lever 150, so that when the upper locking surface 152 of the first latch 160 faces the first latch groove, the first latch 160 extends into the first latch groove, and the deadbolt 100 is locked. At the same time, the magnet 142 moves away from the Hall sensor 141, and the Hall sensor 141 cannot sense the magnet 142. As a result, the Hall sensor 141 generates a second Hall signal. When the control unit 310 receives the second Hall signal, it determines that the deadbolt 100 is in the locked state.

[0084] Therefore, the lock 100 of this utility model can be assisted by the Hall sensor 141 to determine whether the lock 100 is in a locked state, a locked reset state, an unlocked state, or an unlocked reset state, so that the control unit 310 can accurately monitor the state of the lock 100.

[0085] In one embodiment, combined Figure 5 , Figure 6 and Figure 8The lock includes a housing 143 and a knob 144. The rotating shaft 111, the gear plate 120, the linkage ring 118, the photoelectric sensor 114, the Hall sensor 141, the motor 115, and the control unit 310 are all installed inside the housing 143. The rotating shaft 111 protrudes outside the housing 143. The lock cylinder lever 150 is inserted into the protruding end of the rotating shaft 111 relative to the housing 143, and the lock cylinder lever 150 is fixedly connected to the rotating shaft 111. The knob 144 is pivotally mounted on the housing 143, and the knob 144 and the rotating shaft 111 are located on opposite sides of the housing 143. The other end of the rotating shaft 111 is inserted into the knob 144, and the rotating shaft 111 is fixedly connected to the knob 144.

[0086] The user can rotate the knob 144, which in turn rotates the shaft 111, the lock cylinder lever 150, and the first bolt 160, causing the first bolt 160 to extend or retract relative to the first bolt groove, thereby locking or unlocking the deadbolt 100. It can be understood that the locking or unlocking of the deadbolt 100 can be achieved by physically rotating the knob 144. In this embodiment, it is recommended that the knob 144 and the shaft 111 be integrally formed, but this should not be construed as a limitation of this utility model.

[0087] In a further embodiment, combined with Figure 5 , Figure 12 , Figures 14 to 17 The knob 144 is provided with an indicator line 145, the orientation of which is the same as the orientation of the upper locking surface 152 of the lock cylinder lever 150. Since the knob 144 is fixed to the rotating shaft 111, when the lock cylinder lever 150 rotates, the first latch 160 extends into the first latch groove, and the upper locking surface 152 faces the first latch groove. Simultaneously, the knob 144 rotates with the rotating shaft 111, causing the indicator line 145 to point towards the first latch groove, indicating that the lock 100 is in the locked state. Conversely, when the lock cylinder lever 150 rotates, causing the upper locking surface 152 to no longer face the first latch groove, the knob 144 rotates synchronously, causing the indicator line to no longer point towards the first latch groove, indicating that the lock 100 is in the unlocked state.

[0088] In one embodiment, combined Figure 8 and Figure 10 The lock also includes a circuit board 146, which is installed inside the housing 143. The photoelectric sensor 114 and the Hall sensor 141 are both integrated on the circuit board 146.

[0089] In summary, when a user holds the handle of the latch lock in this utility model's combination lock, they can touch the touch module on the handle to trigger the unlocking of the deadbolt. This allows the deadbolt to automatically unlock simultaneously while the user is unlocking the latch lock by operating the handle, thereby reducing the unlocking steps of the combination lock and improving the user experience.
