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

[0006] The primary object of the present invention is to solve at least one of the above problems and provide a combination lock.

[0007] To achieve the various objectives of the present invention, the following technical solutions are adopted in the present invention:

[0008] To meet one of the objectives of the present invention, a combination lock is provided, which includes a control unit and a fixed lock and a deadbolt lock that are separately arranged. The fixed lock includes a motor, a first transmission mechanism, and a first lock tongue. The motor is used to respond to a drive control signal and drive the first transmission mechanism to drive the first lock tongue to extend and retract.

The handle is arranged to rotatably drive the second transmission mechanism to link the second lock tongue to extend and retract. The control unit is used to receive the target electrical signal output by the touch control module and output the drive control signal to the motor based on the target electrical signal. The touch control module includes a touch control component for triggering the target electrical signal, and the touch control component is exposed and arranged on the handle.

[0009] In one embodiment, the touch control module is a fingerprint verification module. The fingerprint verification module includes a fingerprint verification unit, and the fingerprint verification unit is electrically connected to the touch control component. The touch control component is a fingerprint collection component.

[0011] In one embodiment, the handle includes a vertical rod and a horizontal rod. The second transmission mechanism includes a transmission shaft. Two ends of the transmission shaft are respectively connected to the second lock tongue and the vertical rod, and the touch control module is arranged on the horizontal rod.

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

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

[0014] In one embodiment, the first transmission mechanism includes a lock core dial, a rotating shaft, a toothed disc, a linkage block, and a photoelectric sensor. The lock core dial is respectively connected to the first locking tongue and the rotating shaft. The linkage block is fixedly arranged on the rotating shaft. The toothed disc is sleeved on the rotating shaft. The toothed disc is provided with a transmission block and a plurality of light-shielding sheets. 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-shielding sheets. The plurality of light-shielding sheets are sequentially arranged at intervals along the circumferential direction of the toothed disc. The motor is in transmission connection with the toothed disc.

[0015] In one embodiment, the transmission block extends along the circumferential direction of the toothed disc. The toothed disc is provided with a travel groove. The travel groove and the transmission block are sequentially arranged along the same extension path, and both end faces of the transmission block form two groove walls of the travel groove.

[0016] In one embodiment, both the transmission block and the travel groove span 180°. The toothed disc is provided with four light-shielding sheets, and the four light-shielding sheets are evenly arranged at intervals in the circumferential direction of the toothed disc.

[0017] In one embodiment, the deadlock is further provided with a Hall sensor and a magnet. The magnet is arranged on the rotating shaft. The Hall sensor is arranged on the rotation path of the magnet.

[0018] Compared with the prior art, the present invention has multiple advantages, including but not limited to:

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

[0042] The present invention provides a combination lock. When the user unlocks the deadbolt lock, by touching the touch module on the deadbolt lock of the combination lock, the deadlock can be synchronously and automatically unlocked, so that the user does not need to separately unlock the deadlock and the deadbolt lock in sequence, improving the unlocking efficiency of the combination lock and enhancing the user experience.

[0043] In a typical embodiment of the present invention, in combination withFigure 1 and Figure 2 ,or Figure 3 The combination lock 300 includes a control unit 310, a deadbolt lock 100 and a latch bolt lock 200, wherein the deadbolt lock 100 and the latch bolt lock 200 are separately arranged. The combination lock 300 is installed on a door body 400, and the door body 400 is installed on a door frame. The door frame is provided with two bolt grooves, which are a first bolt groove and a second bolt groove, respectively. The first bolt groove is arranged corresponding to the deadbolt lock 100, and the second bolt groove is arranged corresponding to the latch bolt lock 200.

[0044] 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.

[0045] The oblique bolt lock 200 includes a handle 210, a touch module 220, a transmission mechanism (the transmission mechanism is referred to as a second transmission mechanism) and a lock tongue (the lock tongue is referred to as a second lock tongue 230), the handle 210, the second transmission mechanism and the second lock tongue 230 are sequentially connected in transmission, the handle 210 drives the second lock tongue 230 to extend into the second lock tongue groove through the second transmission mechanism to achieve locking of the oblique bolt lock 200, or the handle 210 drives the second lock tongue 230 to withdraw from the second lock tongue groove through the second transmission mechanism to achieve unlocking of the oblique bolt lock 200. The touch module 220 is electrically connected to the control unit 310.

[0046] Specifically, combined Figure 1 , Figure 3 and Figure 4 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 tongue lock 200.

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

[0048] Combined with Figure 2 , when the user locks or unlocks the combination lock 300, the user's hand holds the handle 210, and the user's hand touches the touch control 221 exposed on the handle 210. The detection unit 222 responds to the touch event of the touch control 221 and generates a target electrical signal. The detection unit 222 outputs the target electrical signal to the control unit 310. The control unit 310 generates a drive control signal based on the target electrical signal, and the control unit 310 outputs the drive control signal to the motor 115 of the deadbolt lock 100 to control the operation of the motor 115, thereby controlling the movement of the first locking tongue 160 through the motor 115, so that the deadbolt lock 100 is unlocked or locked.

[0049] Thus, when the user rotates the handle 210 to unlock the latch lock 200, the user touches the touch module 220, and the touch module 220 generates a corresponding target electrical signal. The control unit 310 generates a drive control signal based on the received target electrical signal, and the control unit 310 controls the operation of the motor 115 through the drive control signal to drive the first locking tongue 160 to operate through the motor 115 to achieve the unlocking of the deadbolt lock 100. It can be understood that when the user rotates the handle 210 to unlock the latch lock 200, the deadbolt lock 100 is also unlocked synchronously, so that the user can unlock with one step without separately unlocking the deadbolt lock 100 and the latch lock 200 respectively, thereby reducing the unlocking steps of the combination lock 300, improving the unlocking efficiency, and enhancing the user experience.

[0050] In one embodiment, combined with Figure 1 and Figure 2 , or Figure 3The touch control module 220 is a switch module. The touch control element 221 of the touch control module 220 is a push switch, and the detection unit 222 is a switch circuit. When a user holds the handle 210, the user can press the push switch to cause the switch circuit to generate a corresponding target electrical signal. In this embodiment, when it is necessary to unlock the combination lock 300, the user holds the handle 210, presses the push switch to correspondingly control the deadlock 100 to unlock, and the user simultaneously rotates the handle 210 to synchronously unlock the latch lock 200, so that the deadlock 100 and the latch lock 200 of the combination lock 300 are synchronously unlocked, improving the unlocking efficiency and the user experience.

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

[0052] After receiving the electrical signal output by the fingerprint acquisition component, the fingerprint verification unit analyzes the corresponding user feature data from the electrical signal. An identity database containing the user feature data of legitimate users is preset in the fingerprint verification unit. The fingerprint verification unit compares the user feature data with each piece of user feature data in the identity database. When the acquired user feature data matches one of the user feature data in the identity database, the fingerprint verification unit sets the corresponding electrical signal as the target electrical signal; otherwise, when the acquired user feature data does not match one of the user feature data in the identity database, the fingerprint verification unit sets the corresponding electrical signal as an invalid electrical signal. The fingerprint verification unit outputs the acquired target electrical signal to the control unit 310, and the control unit 310 controls the deadlock 100 to be unlocked or locked based on the target electrical signal.

[0053] In this embodiment, when it is necessary to unlock the combination lock 300, the user holds the handle 210, and one finger touches the fingerprint acquisition component. The fingerprint acquisition component generates an electrical signal. The fingerprint verification unit determines whether it is a target electrical signal based on the electrical signal. If so, it outputs the target electrical signal to the control unit 310, and the control unit 310 controls the deadlock 100 to be unlocked. The user simultaneously rotates the handle 210 to synchronously unlock the latch lock 200, so that the deadlock 100 and the latch lock 200 of the combination lock 300 are synchronously unlocked, improving the unlocking efficiency and the user experience.

[0054] In one embodiment, in combination with Figure 3 and Figure 4 , the handle 210 includes a vertical rod 211 and a horizontal rod 212. The vertical rod 211 is connected to the horizontal rod 212, and the vertical rod 211 and the horizontal rod 212 are disposed substantially perpendicular to each other. One end of the transmission shaft 240 is inserted into the vertical rod 211. The touch control 221 of the touch control module 220 is disposed on the horizontal rod 212, and the touch control 221 is exposed on the horizontal rod 212. Since the user mainly holds the horizontal rod 212 when holding the handle 210, the touch control 221 is disposed on the horizontal rod 212, which is more convenient for the user to touch the touch control 221 and improves the user experience.

[0055] In this embodiment, the door body 400 includes a front surface 420 and a back surface 410. The horizontal rod 212 faces the back surface 410 of the door body 400, and the horizontal rod 212 is disposed close to the back surface 410. Two side surfaces are provided on the horizontal rod 212, and the two side surfaces are disposed substantially parallel to the door body 400. One of the side surfaces (referred to as the inner side surface, not shown) is disposed opposite to the back surface 410, and the other side surface (referred to as the outer side surface 2121) has the same orientation as the back surface 410, and the outer side surface 2121 is farther from the back surface 410 than the inner side surface. The touch control 221 is exposed on the outer side surface 2121, so that the user can observe the outer side surface 2121. In addition, the touch control 221 is disposed on the outer side surface 2121, which also conforms to ergonomics and is convenient for the user to touch the touch control 221 when holding the handle 210.

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

[0057] In a typical embodiment of the present invention, in combination with Figure 1 and Figure 2 , or, Figure 3 and Figure 4 The control unit 310 is installed in the deadlock 100. Since the deadlock 100 and the latch lock 200 are separately provided, a wired connection or a wireless connection is established between the control unit 310 provided in the deadlock 100 and the touch control module 220 provided in the latch lock 200.

[0058] In one embodiment, in combination with Figure 1 and Figure 2, the control unit 310 is wirelessly connected to the touch module 220. Specifically, a first communication unit 170 is further provided in the deadbolt 100, and the first communication unit 170 is electrically connected to the control unit 310; a second communication unit 250 is provided in the latch bolt 200, and the second communication unit 250 is electrically connected to the touch module 220. The first communication unit 170 and the second communication unit 250 are wirelessly communicatively connected. The control unit 310 and the touch module 220 perform 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 achieve good data communication at a short distance. For example, both the first communication unit 170 and the second communication unit 250 are radio frequency devices, but this should not be construed as a limitation of the present invention.

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

[0060] In a typical embodiment of the present invention, the deadbolt 100 includes the first transmission mechanism and the first latch 160. The first transmission mechanism includes the lock core dial 150. One end of the lock core dial 150 is connected to the lock core of the deadbolt 100. The lock core dial 150 is connected to the first latch 160. The lock core dial 150 drives the first latch 160 to move linearly along the extension direction of the first latch 160, so that the first latch 160 extends into or withdraws from the first latch groove, thereby realizing locking or unlocking of the deadbolt 100.

[0061] The lock core dial 150 is perpendicularly arranged with the first latch 160, and the lock core dial 150 is fixedly arranged with the first latch 160. In combination with Figure 7, the lock core paddle 150 is a flat columnar structure, wherein the lock core paddle 150 includes an adjacent unlocking surface 151 and a locking surface 152, the unlocking surface 151 is perpendicular to the locking surface 152, and the width of the unlocking surface 151 is greater than the width of the locking surface 152. When the lock core paddle 150 is rotated so that the unlocking surface 151 of the lock core paddle 150 faces the first lock tongue groove, the first lock tongue 160 exits from the first lock tongue groove to achieve unlocking; when the lock core paddle 150 is rotated so that the locking surface 152 of the lock core paddle 150 faces the first lock tongue groove, the first lock tongue 160 extends into the first lock tongue groove to achieve locking.

[0062] In a typical embodiment of the present invention, in combination with Figure 8 , the first transmission mechanism further includes a rotating shaft 111, a gear disk 120, a linkage block 113, a photoelectric sensor 114, and the motor 115. The control unit 310 is electrically connected to the photoelectric sensor 114 and the motor 115 respectively, and the motor 115 is used to drive the gear disk 120 to rotate. In combination with Figure 6 , the rotating shaft 111 is connected to the lock core paddle 150. In combination with Figure 11 , the linkage block 113 is arranged on the rotating shaft 111. The gear disk 120 is provided with a gear hole, and the gear disk 120 is sleeved on the rotating shaft 111 through the gear hole. The gear hole is a circular hole, and the section of the rotating shaft 111 corresponding to the gear hole is a cylindrical structure, so that the gear hole is sleeved on the rotating shaft 111, and the gear disk 120 cannot directly drive the rotating shaft 111 to rotate. Alternatively, the aperture of the gear hole is larger than the shaft diameter of the rotating shaft 111, so that there is no transmission fit between the gear hole and the rotating shaft 111, so that the gear disk 120 cannot directly drive the rotating shaft 111 to rotate.

[0063] In combination with Figure 9 and Figure 11 , the gear disk 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 gear disk 120 to rotate, the transmission block 122 arranged 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 through the linkage block 113. 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 dead lock 100 is locked or unlocked.

[0064] Combined with Figure 9 and Figure 10 , a plurality of light shielding sheets 130 are provided on the toothed disk 120. The toothed disk 120 will drive the light shielding sheets 130 to rotate synchronously. The photoelectric sensor 114 is disposed on the rotation path of the light shielding sheets 130. When the toothed disk 120 drives the light shielding sheets 130 to pass by the photoelectric sensor 114, the light shielding sheets 130 will block the light emitted by the photoelectric sensor 114, causing the photoelectric sensor 114 to generate a light shielding signal. The photoelectric sensor 114 outputs the light shielding signal to the control unit 310. Based on the light shielding signal, the control unit 310 obtains the rotation angle of the toothed disk 120 and judges the working state of the deadlock 100.

[0065] In this embodiment, a plurality of light shielding sheets 130 are provided on the toothed disk 120. The plurality of light shielding sheets 130 are evenly distributed in the circumferential direction of the toothed disk 120. For example, if two light shielding sheets 130 are provided on the toothed disk 120, the two light shielding sheets 130 are arranged at 180°; if three light shielding sheets 130 are provided on the toothed disk 120, the three light shielding sheets 130 are arranged in sequence along the circumferential direction of the toothed disk 120, and the angle between two adjacent light shielding sheets 130 is 120°.

[0066] In this embodiment, taking the example that four light shielding sheets 130 are provided on the toothed disk 120 to describe the present invention, but it should not be construed as a limitation to the present invention. Specifically, the four light shielding sheets 130 are arranged in sequence along the circumferential direction of the toothed disk 120, and the angle between two adjacent light shielding sheets 130 is 90°. When the motor 115 drives the toothed disk 120 to rotate, the toothed disk 120 will drive the four light shielding sheets 130 to rotate synchronously. Assume that when the toothed disk 120 does not rotate, the angle when the photoelectric sensor 114 is blocked by one of the light shielding sheets 130 is 0°; when the motor 115 drives the toothed disk 120 to rotate and the photoelectric sensor 114 is blocked by another light shielding sheet 130, the control unit 310 receives the light shielding signal output by the photoelectric sensor 114, and the control unit 310 judges that the toothed disk 120 has rotated 90°.

[0067] The control unit 310 controls the forward and reverse rotations of the motor 115 by outputting the drive control signal to the motor 115, and controls the rotation direction of the toothed disk 120. The control unit 310 controls the rotation of the lock core dial 150 by controlling the rotation of the toothed disk 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 deadlock 100. Moreover, the control unit 310 monitors the rotation angle of the toothed disk 120 through the photoelectric sensor 114 to prevent the rotation angle of the toothed disk 120 from being too large or too small, so that the deadlock 100 can accurately lock or unlock.

[0068] In this embodiment, in combination with Figure 9 , the transmission block 122 extends along the circumferential direction of the gear disk 120, such that both end faces 1221 of the transmission block 122 in the circumferential direction are angled. Either of these two end faces 1221 can be abutted against the linkage block 113 on the rotating shaft 111 to drive the rotation of the rotating shaft 111 via 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 in reverse, the other end face 1221 abuts against the linkage block 113; thereby improving the rotation efficiency of the gear disk 120. In the present invention, it is recommended that the transmission block 122 be arranged to span 180°, that is to say, 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 to quickly abut against the linkage block 113.

[0069] In a typical embodiment of the present invention, a travel groove 121 is provided on the gear disk 120. The travel groove 121 extends along the circumferential direction of the gear disk 120, and the travel groove 121 and the transmission block 122 extend along the same extension path. The travel groove 121 and the transmission block 122 are connected end to end to form an annular structure. Moreover, the two end faces 1221 of the transmission block 122 form the two groove walls of the travel groove 121 in the circumferential direction. In this embodiment, taking the transmission block 122 arranged to span 180° in the circumferential direction and the travel groove 121 also arranged to span 180° in the circumferential direction as an example to describe the present invention, it should not be construed as a limitation to the present invention.

[0070] In combination with Figure 8 and Figure 11 , a linkage ring 118 is further provided on the first transmission mechanism. The linkage ring 118 is sleeved on the rotating shaft 111, and the linkage ring 118 is fixedly arranged with the rotating shaft 111. 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 be integrally formed, but it should not be construed as a limitation to the present invention.

[0071] In combination with Figure 9 and Figure 11, a ring groove 123 is provided on the toothed disc 120. The ring groove 123 is arranged inside the stroke groove 121, that is to say, the ring groove 123 is closer to the gear hole of the toothed disc 120 than the stroke groove 121. The ring groove 123 communicates with the stroke groove 121. The linkage ring 118 is installed in the ring 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, and the two end faces 1221 of the transmission block 122 can selectively abut against the linkage block 113.

[0072] When the toothed disc 120 rotates, one end face 1221 of the transmission block 122 abuts against the linkage block 113. The toothed disc 120 further rotates to drive the linkage block 113 to rotate through the corresponding end face 1221. The linkage block 113 drives the rotating shaft 111 and the lock core dial 150 to rotate in sequence, and then drives the first lock tongue 160 to move linearly, so as to realize the first lock tongue 160 extending into or withdrawing from the first lock tongue groove, so as to realize the locking or unlocking of the dead lock 100.

[0073] For the convenience of describing the working principle of the dead lock 100 of the present invention, in combination with Figure 12 and Figure 13 , Figure 12 is a schematic plan view when the rotating shaft, the linkage ring and the photoelectric sensor are assembled. Figure 13 is a schematic plan view of the toothed disc 120. Let the four light-shielding sheets 130 on the toothed disc 120 be the first light-shielding sheet 131, the second light-shielding sheet 132, the third light-shielding sheet 133 and the fourth light-shielding sheet 134 in sequence along the circumferential direction of the toothed disc 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] In combination with Figure 14 , let the dead lock 100 be in the locked and reset state. The first light-shielding sheet 131 is at the photoelectric sensor 114. The photoelectric sensor 114 generates a light-shielding signal. The control unit 310 judges that the dead lock 100 is in the locked and reset state based on the light-shielding signal. And, the first end face 1222 abuts against the linkage block 113 of the linkage ring 118.

[0075] In combination with Figure 14 and Figure 15When the deadlock 100 needs to be unlocked, the control unit 310 outputs the drive control signal to the motor 115 to control the forward rotation of the motor 115. The motor 115 drives the gear disk 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° through the linkage block 113. Among them, the first light-shielding piece 131 on the gear disk 120 will leave the photoelectric sensor 114, and the photoelectric sensor 114 no longer generates a light-shielding signal but generates a photoelectric signal. After the control unit 310 receives the photoelectric signal, the control unit 310 determines that the first light-shielding piece 131 has left the position of the photoelectric sensor 114. At the same time, the fourth light-shielding piece 134 on the gear disk 120 will rotate counterclockwise by 90° to the position of the photoelectric sensor 114. The fourth light-shielding piece 134 will block the light emitted by the photoelectric sensor 114 and generate a light-shielding signal again. After the control unit 310 receives the light-shielding signal, it determines that the fourth light-shielding piece 134 has rotated to the position of the photoelectric sensor 114 and determines that the deadlock 100 has been unlocked. At the same time, the first end face 1222 on the gear disk 120 also drives the linkage ring 118, the rotating shaft 111, the lock core dial 150, and the first locking tongue 160 to rotate, so that the first locking tongue 160 retracts relative to the first locking tongue groove to complete the unlocking, and the deadlock 100 is in the unlocked state.

[0076] Combined with Figure 15 and Figure 16, after the deadbolt 100 is in the unlocked state, the control unit 310 controls the motor 115 to reverse, and the motor 115 drives the gear disk 120 to rotate clockwise by 180°, so that the first end face 1222 of the transmission block 122 rotates clockwise by 180° to separate from the linkage block 113, and the second end face 1223 of the transmission block 122 rotates clockwise by 180° synchronously to abut against the linkage block 113. During the process of the gear disk 120 rotating clockwise by 180°, neither the first end face 1222 nor the second end face 1223 is linked with the linkage block 113, so that the gear disk 120 does not drive the linkage ring 118, the rotating shaft 111, the lock core dial 150 and the first locking tongue 160 to rotate through the linkage block 113. Moreover, during the process of the gear disk 120 rotating clockwise by 180°, the fourth light shielding piece 134 will leave the photoelectric sensor 114, so that the photoelectric sensor 114 generates a photoelectric signal, and the first light shielding piece 131 and the second light shielding piece 132 pass through the photoelectric sensor 114 in sequence. The photoelectric sensor 114 generates a light shielding signal, a photoelectric signal and a light shielding signal based on the first light shielding piece 131 and the second light shielding piece 132 in sequence, and the second light shielding piece 132 stays at the photoelectric sensor 114. The control unit 310 sequentially receives the photoelectric signal and the light shielding signal output by the photoelectric sensor 114. Thus, the control unit 310 correspondingly judges that the deadbolt 100 is in the unlocked and reset state, preparing for locking the deadbolt 100 later.

[0077] Combined with Figure 16 and Figure 17, when the deadlock 100 is in the unlocked reset state and the deadlock 100 needs to be locked, the control unit 310 outputs the drive control signal to the motor 115 to control the motor 115 to reverse. The motor 115 drives the gear disk 120 to rotate 90° clockwise, so that the second end face 1223 of the transmission block 122 drives the abutted linkage block 113 to rotate 90° clockwise, and the linkage block 113 drives the linkage ring 118, the rotating shaft 111, the lock core dial 150 and the first locking tongue 160 to move synchronously, so that the first locking tongue 160 extends out of the first locking tongue groove and inserts into the first locking tongue groove, thereby making the deadlock 100 in the locked state. Moreover, during the process of the gear disk 120 rotating 90° clockwise, the second light shielding piece 132 will leave the photoelectric sensor 114, so that the photoelectric sensor 114 generates a photoelectric signal; then the third light shielding piece 133 will rotate 90° clockwise to the photoelectric sensor 114, and the photoelectric sensor 114 correspondingly generates a light shielding signal, and the third light shielding piece 133 stays at the photoelectric sensor 114. The control unit 310 sequentially receives the photoelectric signal and the light shielding signal output by the photoelectric sensor 114. Thus, the control unit 310 correspondingly judges that the deadlock 100 is in the locked state.

[0078] Combined with Figure 17 and Figure 14After the deadlock 100 is in the locked state, the control unit 310 controls the motor 115 to rotate forward. The motor 115 drives the gear disk 120 to rotate counterclockwise by 180°, so that the second end face 1223 of the transmission block 122 rotates counterclockwise by 180° to separate from the linkage block 113, and the first end face 1222 of the transmission block 122 rotates counterclockwise by 180° synchronously to abut against the linkage block 113. During the rotation of the gear disk 120, neither the first end face 1222 nor the second end face 1223 is linked with the linkage block 113, so that the gear disk 120 does not drive the linkage ring 118, the rotating shaft 111, the lock core dial 150 and the first lock tongue 160 to rotate through the linkage block 113. Moreover, during the process of the gear disk 120 rotating counterclockwise by 180°, the third light shielding piece 133 will leave the photoelectric sensor 114, so that the photoelectric sensor 114 generates a photoelectric signal, and the second light shielding piece 132 and the first light shielding piece 131 pass through the photoelectric sensor 114 in sequence. The photoelectric sensor 114 generates a light shielding signal, a photoelectric signal and a light shielding signal based on the second light shielding piece 132 and the first light shielding piece 131 in sequence, and the first light shielding piece 131 stays at the photoelectric sensor 114. The control unit 310 receives the photoelectric signal and the light shielding signal output by the photoelectric sensor 114 in sequence. Thus, the control unit 310 correspondingly judges that the deadlock 100 is in the locked and reset state, preparing for unlocking the deadlock 100 later.

[0079] Thus, the above text describes the whole process of the deadlock 100 of the present invention from the locked and reset state - the unlocked state - the unlocked and reset state - the locked state - the locked and reset state. The deadlock 100 can judge the state of the deadlock 100 through the received photoelectric signal and light shielding signal, so that the control unit 310 can accurately control the operation of the deadlock 100 only through a single photoelectric sensor 114, reducing the number of sensors of the deadlock 100 and lowering the production cost of the deadlock 100.

[0080] In one embodiment, in combination with Figure 10 、 Figure 11 and Figure 12 On the first transmission mechanism, a Hall sensor 141 and a magnet 142 are further provided. The magnet 142 is arranged on the rotating shaft 111. When the rotating shaft 111 rotates, the rotating shaft 111 will drive the magnet 142 to rotate synchronously. The Hall sensor 141 is arranged on the rotation path of the magnet 142. When the magnet 142 approaches the Hall sensor 141, the Hall sensor 141 will generate a Hall signal.

[0081] In this embodiment, the Hall sensor 141 is disposed adjacent to the photoelectric sensor 114, and the Hall sensor 141 is disposed at a 90° angle with respect to the first lock tongue groove. The magnet 142 is disposed at a 90° angle with respect to the linkage block 113. Since the rotating shaft 111 and the lock core dial 150 are fixedly provided, and the rotating shaft 111 and the lock core dial 150 rotate synchronously, the orientation of the magnet 142 and the orientation of the locking surface 152 of the lock core dial 150 are set to be the same.

[0082] Combined with Figure 14 and Figure 15 , when the control unit 310 controls the motor 115 to operate, the motor 115 drives the gear disk 120 to rotate, the gear disk 120 drives the rotating shaft 111 to rotate, so that the unlocking surface 151 of the rotating shaft 111 faces the first lock tongue groove, and the first lock tongue 160 withdraws from the first lock tongue groove, and the deadlock 100 is unlocked. At the same time, the locking surface 152 of the rotating shaft 111 faces the Hall sensor 141, the magnet 142 approaches the Hall sensor 141, the Hall sensor 141 senses the magnet 142, generates a first Hall signal, and when the control unit 310 receives the first Hall signal, it determines that the deadlock 100 is in the unlocked state.

[0083] Combined with Figure 16 and Figure 17 , when the control unit 310 controls the motor 115 to operate, the motor 115 drives the first lock tongue 160 through the gear disk 120, the rotating shaft 111 and the lock core dial 150, so that when the locking surface 152 of the first lock tongue 160 faces the first lock tongue groove, the first lock tongue 160 extends into the first lock tongue groove, and the deadlock 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. Thus, the Hall sensor 141 generates a second Hall signal, and when the control unit 310 receives the second Hall signal, it determines that the deadlock 100 is in the locked state.

[0084] Therefore, the deadlock 100 of the present invention can use the Hall sensor 141 to assist in determining whether the deadlock 100 is in the locked state, the locked reset state, the unlocked state, and the unlocked reset state, so that the control unit 310 can accurately monitor the state of the deadlock 100.

[0085] In one embodiment, combined with Figure 5 , Figure 6 and Figure 8The deadbolt lock includes a housing 143 and a knob 144. The shaft 111, the toothed disc 120, the linkage ring 118, the photoelectric sensor 114, the Hall sensor 141, the motor 115 and the control unit 310 are all installed in the housing 143. The shaft 111 protrudes from the housing 143. The lock core paddle 150 is inserted into the end of the shaft 111 protruding from the housing 143, and the lock core paddle 150 is fixedly connected to the shaft 111. The knob 144 is pivotally mounted on the housing 143, and the knob 144 and the shaft 111 are arranged on both sides of the housing 143, and the other end of the shaft 111 is inserted into the knob 144, and the shaft 111 and the knob 144 are fixedly connected.

[0086] 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.

[0087] In a further embodiment, in combination Figure 5 , Figure 12 , Figures 14 to 17 , an indication mark line 145 is provided on the knob 144, and the direction of the indication mark line 145 is the same as the direction of the upper locking surface 152 of the lock core paddle 150, and the knob 144 is fixed to the rotating shaft 111. When the lock core paddle 150 rotates, the first lock tongue 160 extends into the first lock tongue groove, and the upper locking surface 152 faces the first lock tongue groove, the knob 144 also rotates synchronously with the rotating shaft 111, so that the indication mark line 145 also points to the first lock tongue groove, indicating that the deadbolt 100 is in a locked state. Conversely, when the lock core paddle 150 rotates, so that the upper locking surface 152 no longer faces the first lock tongue groove, the knob 144 rotates synchronously, so that the indication mark line no longer points to the first lock tongue groove, indicating that the deadbolt 100 is in an unlocked state.

[0088] In one embodiment, in combination Figure 8 and Figure 10 The deadbolt lock is further provided with a circuit board 146 , and the circuit board 146 is installed in the housing 143 . The photoelectric sensor 114 and the Hall sensor 141 are both integrated on the circuit board 146 .

[0089] In summary, when the user holds the handle of the deadbolt lock in the combination lock of the present invention, the touch module on the handle can be touched, and the unlocking of the deadlock is triggered through the touch module, so that during the process of the user operating the handle to unlock the deadbolt lock, the deadlock can be automatically synchronized to unlock, reducing the unlocking steps of the combination lock and improving the user experience.
