In addition, the detection member 140 can also be set as a photoelectric switch or a limit switch.

[0036] A gear set 530 is provided between the output shaft of the motor 520 and the dial head 511. The output shaft of the motor 520 is connected to the dial head 511 through the gear set 530. When the output shaft of the motor 520 rotates, the dial head 511 can be driven to rotate through the gear set 530. Figure 3 The gear set 530 includes a first gear 531 and a second gear 532. The first gear 531 is fixedly disposed on the output shaft of the motor 520, and the second gear 532 is fixedly disposed on the dial head 511. The first gear 531 meshes with the second gear 532. The first gear 531 and the second gear 532 are both configured as spur gears, and the rotation axis of the dial head 511 is parallel to the axis of the output shaft of the motor 520. Of course, in some embodiments, the first gear 531 and the second gear 532 may also be configured as bevel gears, so that an angle may be formed between the rotation axis of the dial head 511 and the axis of the output shaft of the motor 520, and the installation orientation of the motor 520 has greater flexibility.

[0037] In some embodiments, the gear set 530 may further include a third gear, which is rotatably disposed on the first handle assembly 200 , and the first gear 531 and the second gear 532 are both meshed with the third gear.

[0038] In some embodiments, the output shaft of the motor 520 and the dial head 511 may also be connected via a belt structure or a coupling, so that the motor 520 can drive the dial head 511 to rotate.

One end of the first square rod 132 is plug-connected with the dial head 511, and the other end of the first square rod 132 is fixedly connected with the dial sleeve 130. When the dial head 511 rotates, the dial sleeve 130 can be driven to rotate by the first square rod 132. During installation, a portion of the end of the first square rod 132 close to the dial head 511 can be cut off according to the thickness of the door leaf, so that the length of the first square rod 132 matches the thickness of the door leaf. The first square rod 132 and the dial sleeve 130 can be formed into an integrated structure to reduce the number of parts and simplify assembly.

[0040] In some embodiments, the first square rod 132 can also be plug-connected with the pull sleeve 130. To adapt to the thickness of the door leaf, a portion can be cut off at both ends of the first square rod 132. In addition, the pull head 511 and the pull sleeve 130 can also be connected through a coupling or other structure.

[0041] Reference Figure 2The first handle assembly 200 includes a first screw 210 and a first handle 220, a first mounting cylinder 230 and a base 240 arranged in sequence. The first screw 210 is inserted through the base 240 and the first mounting cylinder 230, and the first screw 210 is screwed to the first handle 220 to clamp the first mounting cylinder 230 between the first handle 220 and the base 240. The motor 520 and the lock head 510 are both inserted into the inner cavity of the first mounting cylinder 230, and the signal input module 410 is arranged on the first handle 220. Through this structure, during assembly, the motor 520 and the lock head 510 can be inserted into the first mounting cylinder 230 first, and then the first handle assembly 200 can be assembled, and the assembly of the first handle assembly 200 is relatively simple. The individual parts of the first handle assembly 200 are small in size and simple in structure, which can be easily processed.

[0042] Reference Figure 2 and Figure 4 The second handle assembly 300 is rotatably provided with a knob assembly 610, and the dial sleeve 130 is connected to the knob assembly 610 so that the dial sleeve 130 can rotate with the knob assembly 610. The second handle assembly 300 is also provided with a locking structure that matches the knob assembly 610, and the locking structure can limit the rotation of the knob assembly 610 to achieve the function of locking the door from the inside.

[0043] Specifically, the knob assembly 610 includes a knob member 611 and a second square rod 612. One end of the second square rod 612 is plugged into the dial sleeve 130, and the other end of the second square rod 612 is plugged into the knob member 611, so that the dial sleeve 130 is connected to the knob assembly 610. The side wall of the second square rod 612 is concave to form a space-avoiding groove 613. The locking structure includes a locking block 621. The locking block 621 is slidably disposed on the second handle assembly 300. The locking block 621 is provided with a locking hole 622 that matches the second square rod 612. The second square rod 612 is inserted into the locking hole 622, that is, the locking block 621 is sleeved on the second square rod 612.

[0044] When the door needs to be locked from the inside, the bolt assembly 120 is first driven to slide out of the lock housing 110, and then the locking block 621 is pushed to stagger the air-avoiding groove 613 and the locking hole 622. At this time, the second square rod 612 cooperates with the locking hole 622, and the knob 611 and the first square rod 132 cannot rotate, so that the dial sleeve 130 cannot rotate either. At this time, the unlocking cannot be performed by the key or the motor 520. The locking block 621 is pushed to move so that the air-avoiding groove 613 is located in the locking hole 622. At this time, the first square rod 132 and the locking hole 622 are no longer matched, and the first square rod 132 can rotate relative to the locking hole 622. At this time, the dial sleeve 130 can be driven to rotate by rotating the knob 611, and the dial sleeve 130 can also be driven to rotate by the motor 520 or the key.

[0045] In some embodiments, the second square rod 612 may also be fixedly connected to the knob 611 and / or the pull sleeve 130 by means of screws or other structures. The knob 611 and the second square rod 612 may also be formed as an integrated structure.

[0046] In some embodiments, the locking structure may include a locking block 621 and a limiting column. One of the knob 611 and the locking block 621 is fixedly provided with the limiting column, and the other is provided with a limiting hole for fitting the limiting block. When the locking block 621 is pushed to slide so that the limiting column is inserted into the limiting hole, the knob 611 can be limited from rotating. When the limiting column is moved out of the limiting hole, the knob 611 can rotate. The limiting column is preferably conical so that the limiting column can be guided to be inserted into the limiting hole.

[0047] Reference Figure 2 and Figure 4 The second handle assembly 300 includes a second screw 310, a second handle 320 and a second mounting tube 330. The lock housing 110, the second mounting tube 330 and the second handle 320 are arranged in sequence. The second screw 310 is inserted into the lock housing 110 and the second mounting tube 330, and the second screw 310 is screwed to the second handle 320 to sandwich the second mounting tube 330 between the lock housing 110 and the second handle 320. With this structure, during assembly, the knob assembly 610 can be inserted into the second mounting tube 330 first, and then the second handle assembly 300 can be assembled. The assembly of the second handle assembly 300 is relatively simple. The single parts of the second handle assembly 300 are small in size and simple in structure, which can be easily processed.

[0048] A battery compartment 331 is provided in the second installation tube 330 . A battery can be installed in the battery compartment 331 , and the electronic device 400 can be powered by the battery.

[0049] The above-mentioned door lock system can be installed in occasions where the door leaf thickness is small, such as glass doors. It can also be installed in some occasions where it is inconvenient to make a groove in the door leaf to place the lock body 100. Of course, in actual installation and use, it is not limited to the above-mentioned occasions.

[0050] A touch switch 340 is also provided on the second handle 320, and the touch switch 340 is electrically connected to the main control module 420. When the user needs to unlock and open the door, the second handle 320 can be held. When the finger touches the touch switch 340, the main control module 420 controls the motor 520 to operate, thereby driving the bolt assembly 120 to slide and retract into the lock housing 110, so that the door can be quickly unlocked and opened.

[0051] The lock cylinder 510 is also provided with a lock core (not shown in the figure) and other structures. When the key is not inserted into the lock core, the lock core is stuck in the lock cylinder and cannot rotate. When the matching key is inserted into the lock core, the lock core can be unstuck, and the key and the lock core can rotate. After the key is inserted into the lock core, the end of the key can be directly inserted into the shift block 131; or a transmission block is slidably arranged on the lock cylinder. When the key is not inserted into the lock core, the transmission block is only inserted into the lock core. After the key is inserted into the lock core, the transmission block is pushed to move, so that the transmission block is inserted into the lock core and the shift block 131 at the same time. In this way, the shift block 131 can rotate with the matching key.

[0052] Of course, the embodiments of the present invention are not limited to the above-mentioned lock head 150 , and those skilled in the art may also adopt a lock head 150 with other structures.

The button 6111 is slidably inserted into the mounting block 6112 so that the button 6111 can extend out of and retract into the mounting block 6112. The spring 6113 is disposed between the mounting block 6112 and the button 6111. The button 6111 is provided with a V-shaped limiting groove 6115 and a slide groove 6116 connected to one side of the limiting groove 6115. One end of the hook member 6114 is connected to the mounting block 6112, and the other end is located in the slide groove 6116.

[0054] When in use, the button 6111 can be pressed to move the button 6111 toward the mounting block 6112, and the end of the hook 6114 can move along the slide groove 6116 into the limiting groove 6115. The button 6111 can be released to allow the hook 6114 to be hung in the limiting groove 6115, so that the button 6111 can be retracted into the mounting block 6112 to make the second handle assembly 300 beautiful. Pressing the button 6111 again can cause the end of the hook 6114 to slide along the limiting groove 6115 and move out to the slide groove 6116 to release the button 6111. The spring 6113 can push the button 6111 to extend, and the end of the hook 6114 slides along the slide groove 6116, so that the user can turn the button 6111 to drive the knob assembly 610 to rotate.

[0055] As described above, in an embodiment of the invention, the lock head 510 and the motor 520 share the first square rod 132. Only the first square rod 132 needs to be set between the first handle assembly 200 and the lock body 100 to realize unlocking and locking in both key-driven and motor-driven modes. The structure is simple, and no additional transmission structure is required to connect the motor 520 and the pull sleeve 130. The transmission chain structure of the entire door lock system can be simplified, the number of transmission components can be reduced, and the cost can be reduced.
