[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] Reference Figure 1 、 2 As shown in Figures 3 and 4, the lock device according to the embodiment of the first aspect of the present invention includes an installation box 100, a lock tongue 200, a rack 300 and a motor 400. One end of the lock tongue 200 is rotatably mounted on the side wall of the installation box 100. One end of the lock tongue 200 is provided with a transmission part 210. The transmission part 210 has an outer circumferential surface, and the outer circumferential surface is provided with external teeth 211; the rack 300 is installed in the installation box 100 so as to be movable up and down. One side of the rack 300 has first gear teeth 310, and the first gear teeth 310 are engaged with the external teeth 211; the motor 400 is installed in the installation box 100, and a linkage structure 500 is provided between the rotating shaft of the motor 400 and the rack 300. The rotating shaft can drive the rack 300 to move up and down through the linkage structure 500.

[0032] By providing a motor 400, the motor 400 can drive the rack 300 to move up and down through the linkage structure 500, and the rack 300 can drive the lock tongue 200 to rotate through the transmission part 210, and then the lock tongue 200 can be controlled to flip up and down by the motor 400. When the door needs to be locked, the user only needs to start the motor 400, which is convenient to use.

[0033] Specifically, if Figure 4 As shown, the sliding door includes two door bodies 700 that can move left and right, and the installation box 100 is installed on one of the door bodies 700, as shown in FIG. Figure 1 As shown, the lock tongue 200 is perpendicular to the horizontal plane when the lock tongue 200 is in a normal state; after the two door bodies 700 are unfolded, as shown in FIG. Figure 1 、 3 As shown in Figure 4, when the door needs to be locked, the user starts the motor 400, and the motor 400 drives the rack 300 to move upward through the linkage structure 500. Since the rack 300 is engaged with the outer teeth 211 on the transmission part 210 through the first gear teeth 310, the rack 300 drives the transmission part 210 to rotate when it moves upward, and the transmission part 210 drives the lock tongue 200 to flip downward, so that the lock tongue 200 is parallel to the horizontal plane, and then under the obstruction of the lock tongue 200, the two door bodies 700 cannot move relative to each other, so that the two door bodies 700 remain in the unfolded state; when the door needs to be opened, the user drives the motor 400 again to start, so that the lock tongue 200 flips upward, so that the lock tongue 200 is perpendicular to the horizontal plane, and the two door bodies 700 are no longer blocked by the lock tongue 200, so that one of the door bodies 700 can move relative to the other door body 700, so that the two door bodies 700 overlap.

[0034] In some embodiments of the present invention, Figure 2 、 3 As shown, the linkage structure 500 includes a gear set 510, a worm 520 and a second gear tooth 530. The gear set 510 is respectively engaged with the worm 520 and the second gear tooth 530. The worm 520 is arranged on the rotating shaft, and the second gear tooth 530 is arranged on the other side of the rack 300. The linkage structure 500 adopts the above structure, which can increase the driving force for driving the rack 300 to move.

[0035] During operation, the rotating shaft of the motor 400 drives the worm 520 to rotate. Since the worm 520 and the second gear teeth 530 of the rack 300 are engaged with the gear set 510, the worm 520 can drive the rack 300 to move up and down through the gear set 510 when it rotates.

[0036] In some embodiments of the present invention, Figure 5 、 6 As shown, it also includes a torsion spring 600, and the transmission part 210 is rotatably mounted on the mounting box 100. The torsion spring 600 is arranged between one end of the lock tongue 200 and the transmission part 210. The two ends of the torsion spring 600 are respectively connected to one end of the lock tongue 200 and the transmission part 210. The transmission part 210 drives the lock tongue 200 to rotate through the torsion spring 600.

[0037] Since the transmission part 210 drives the lock tongue 200 to rotate through the torsion spring 600, when the door is opened and the door body 700 presses against the lock tongue 200, the motor 400 will not be blocked, and the motor 400 can still drive the transmission part 210 to rotate. The transmission part 210 can drive the torsion spring 600 to twist and deform. When the door body 700 is released, since the door body 700 does not press against the lock tongue 200, the torsion spring 600 can elastically recover, and then the torsion spring 600 drives the lock tongue 200 to flip upward, thereby realizing the automatic retraction of the lock tongue 200 and ensuring that the door body 700 can open the door.

[0038] Specifically, if Figure 5 、 6 As shown, the torsion spring 600 includes a spiral portion 610, a first left and right extension portion 620 and a second left and right extension portion 630, the first left and right extension portion 620 is connected to the left end of the spiral portion 610, and the second left and right extension portion 630 is connected to the right end of the spiral portion 610, the first left and right extension portion 620 is inserted into one end of the lock tongue 200, and the second left and right extension portion 630 is inserted into the transmission portion 210.

[0039] In a further embodiment of the present invention, Figure 6 As shown, an accommodating cavity 220 for accommodating the torsion spring 600 is provided between one end of the lock tongue 200 and the transmission part 210 , so that the lock tongue 200 and the transmission part 210 can be close to each other, making the structure of the lock compact.

[0040] In a further embodiment of the present invention, Figure 6 As shown, one end of the lock tongue 200 has a connecting shaft 230, and the lock tongue 200 is rotatably mounted on the installation box 100 through the connecting shaft 230. The transmission part 210 is rotatably sleeved outside the connecting shaft 230, so that the transmission part 210 does not need to be provided with a separate rotating shaft, making the structure of the transmission part 210 simple; when the door body 700 presses against the lock tongue 200, the motor 400 can drive the transmission part 210 to rotate relative to the connecting shaft 230.

[0041] In some embodiments of the present invention, Figure 1 As shown, the locking tongue 200 is located in the middle of the installation box 100 in the left-right direction, which is more convenient for installation and use.

[0042] In some embodiments of the present invention, Figure 1 、 2 As shown, the side wall of the installation box 100 has a placement cavity 110 for placing batteries. A circuit board 120 is installed in the installation box 100. The circuit board 120 is electrically connected to the motor 400 and the battery respectively. The battery is provided to make the lock compact and does not need to be connected to the mains.

[0043] In a further embodiment of the present invention, Figure 1 As shown, the placement cavity 110 is located above, below or below the lock tongue 200 to fully utilize the space of the lock and make the lock compact.

[0044] In some embodiments of the present invention, Figure 1 、 7 As shown, the side wall of the mounting box 100 has a groove 130 that can accommodate the lock tongue 200. One end of the lock tongue 200 is rotatably mounted on the bottom of the groove 130. When the rack 300 drives the lock tongue 200 to rotate through the transmission part 210, the lock tongue 200 can extend out of the groove 130 or be retracted into the groove 130. By providing the groove 130, the lock can be retracted into the groove 130 when there is no need to lock the door body 700, making the lock more beautiful.

[0045] In some embodiments of the present invention, Figure 8 As shown, the mounting box 100 has a slide groove 140 for guiding the movement of the rack 300. A portion of the rack 300 is arranged in the slide groove 140 so as to be movable up and down, so that the movement of the rack 300 is more stable.

[0046] In some embodiments of the present invention, the mounting box 100 , the locking tongue 200 , the gear set 510 , the worm 520 , and the rack 300 are all made of metal, so that the lock has a strong load-bearing capacity and is sturdy.

[0047] The sliding door according to the second embodiment of the present invention includes two door bodies 700 and the lock according to the first embodiment, and the lock is installed on one of the door bodies 700.

[0048] By providing the lock device according to the first embodiment, only the motor needs to be driven to lock the sliding door, which is convenient to use.
