[0035] Embodiment 1

[0036] like Figure 1 As shown, the lacing mechanism provided by the embodiment of the utility model includes: a module shell, and a power supply, a driving assembly 300, a transmission assembly and a winding drum 500 arranged in the module shell, the power supply is electrically connected to the driving assembly 300, and the transmission assembly is transmission-connected to the driving assembly 300 and the winding drum 500 respectively; the module shell includes a module upper cover 110 and a module lower cover 120, the module upper cover 110 covers the open end of the module lower cover 120, and is connected to the module lower cover 120 by bonding, the module upper cover 110 is provided with a first avoidance hole 111, the winding drum 500 is located in the first avoidance hole 111, and a winding seal is provided between the winding drum 500 and the inner peripheral wall of the first avoidance hole 111.

[0037] The module upper cover 110 and the module lower cover 120 are both in the shape of an open shell, and the openings are opposite to each other. The module upper cover 110 and the module lower cover 120 are connected by bonding, and a chamber for accommodating the power supply, the driving component 300 and the transmission component is formed therebetween. Figure 6As shown, the sun gear 410 is rotatably connected to the module upper cover 110 and the module lower cover 120 respectively through the sun gear shaft 411. The first avoidance hole 111 is a through hole and is provided on the inner wall of the module upper cover 110 opposite to the movable inner gear ring 430. The diameter of the first avoidance hole 111 is smaller than the diameter of the movable inner gear ring 430. The winding drum 500 is located in the first avoidance hole 111, so that the rope can be wound on the winding drum 500 through the first avoidance hole 111. During assembly, the power supply, the drive assembly 300, the transmission assembly and the winding drum 500 can be assembled in the module housing first, and then the module housing can be installed in the required position for easy assembly and installation.

[0038] Both ends of the rope are fixed to the winding drum 500 and wound on the winding drum 500. The power supply is set as a battery 200, which is used to provide power to the driving component 300. The driving component 300 drives the sun gear 410 to rotate, and the sun gear 410 drives the planetary gear 420 to rotate. The planetary gear 420 drives the movable inner ring gear 430 and the winding drum 500 to rotate. The driving component 300 drives the winding drum 500 to rotate in different directions, thereby achieving tightening or loosening accordingly. When external water or water vapor comes into contact with the module shell, since the module upper cover 110 and the module lower cover 120 are connected by bonding, the gap between the module upper cover 110 and the module lower cover 120 can be sealed, and a winding seal is provided between the winding drum 500 and the inner circumferential wall of the first avoidance hole 111, which can seal the gap between the winding drum 500 and the inner circumferential wall of the first avoidance hole 111, thereby preventing water or water vapor from entering the interior of the module shell, thereby protecting the power supply, drive assembly 300 and transmission assembly in the module shell.

[0039] As an implementation method, Figure 5 As shown, the winding seal comprises a winding seal ring 510, which is sleeved on the outer circumference of the winding drum 500 and abuts against the inner circumferential wall of the first avoidance hole 111. The winding seal ring 510 blocks the gap between the winding drum 500 and the first avoidance hole 111, thereby improving the sealing between the winding drum 500 and the first avoidance hole 111.

[0040] like Figure 2 As shown, the transmission assembly includes a sun gear 410, a planetary gear 420 and a movable inner ring gear 430. The drive assembly 300 is in transmission connection with the sun gear 410. The planetary gears 420 are respectively meshed with the sun gear 410 and the movable inner ring gear 430. The movable inner ring gear 430 is located in the first avoidance hole 111 and is fixedly connected to the winding reel 500. A movable seal is provided between the movable inner ring gear 430 and the inner circumferential wall of the first avoidance hole 111.

[0041] Specifically, the movable inner gear ring 430 is annular, and the inner circumferential wall of the movable inner gear ring 430 is provided with meshing teeth that cooperate with the planetary gear 420. One end of the movable inner gear ring 430 is located in the first avoidance hole 111 and is fixedly connected to the winding disk 500. Specifically, the winding disk 500 and the movable inner gear ring 430 are an integrally formed structure to improve the stability of the connection between the two. The planetary gear 420 is located in the inner ring of the movable inner gear ring 430 and meshes with the movable inner gear ring 430. One end of the sun gear 410 is inserted into the movable inner gear ring 430 from the side of the movable inner gear ring 430 away from the winding disk 500, and meshes with the planetary gear 420. The part of the movable inner gear ring 430 located in the first avoidance hole 111 is sleeved with a movable seal, and the movable seal abuts against the inner circumferential wall of the first avoidance hole 111 to improve the sealing between the movable inner gear ring 430 and the module upper cover 110.

[0042] The movable sealing member includes an O-ring or a Y-ring 431, etc. In this embodiment, Figure 5 As shown, the movable seal includes a Y-shaped seal ring 431, which is sleeved on the outer periphery of the movable inner gear ring 430 and abuts against the inner peripheral wall of the first avoidance hole 111, and the opening of the Y-shaped seal ring 431 faces the winding disk 500. When the external force is transmitted to the Y-shaped seal ring 431 through the winding disk 500, the radial dimension of the Y-shaped seal ring 431 increases because the opening of the Y-shaped seal ring 431 faces the winding disk 500, thereby further improving the sealing between the movable inner gear ring 430 and the module upper cover 110.

[0043] like Figure 1 , Figure 2 and Figure 6 As shown, the transmission assembly also includes a fixed inner gear ring 440, which is fixedly disposed on the module upper cover 110 and meshes with the planetary gear 420. The number of teeth of the fixed inner gear ring 440 is less than the number of teeth of the movable inner gear ring 430. Specifically, the number of teeth of the fixed inner gear ring 440 is 36, and the number of teeth of the movable inner gear ring 430 is 39.

[0044] Specifically, the fixed inner gear ring 440 is coaxially arranged with the movable inner gear ring 430, and is fixedly installed on the inner wall of the open end of the module upper cover 110, so as to achieve the fixed position of the fixed inner gear ring 440. The movable inner gear ring 430 is located between the fixed inner gear ring 440 and the inner top wall of the module upper cover 110, and the planetary gear 420 is meshed with the fixed inner gear ring 440 and the movable inner gear ring 430 at the same time. When the driving assembly 300 drives the winding drum 500 to tighten the rope belt, since the fixed inner gear ring 440 is fixed in position, the sun gear 410 drives the planetary gear 420 to run a circle along the 36 meshing teeth of the fixed inner gear ring 440. In the case of coaxiality, the movable inner gear ring 430 is provided with 39 meshing teeth. Therefore, after the planetary gear 420 runs a circle, the movable inner gear ring 430 drives the winding drum 500 to move 3 teeth in the circumferential direction, thereby achieving the effect of decelerating rotation. When the rope is too tight and pulls the winding drum 500 in the opposite direction, the winding drum 500 transmits the force to the planetary gear 420 through the movable inner ring 430. Since the number of teeth of the fixed inner ring 440 is 3 less than that of the movable inner ring 430, theoretically, the fixed inner ring 440 needs to move 3 meshing teeth in the circumferential direction to realize coaxial rotation. However, since the position of the fixed inner ring 440 is fixed, the 3 meshing teeth cannot be rotated in the circumferential direction, and the planetary gear 420 cannot rotate along the fixed inner ring 440. The planetary gear 420 cannot transmit the force to the drive assembly 300 through the sun gear 410, thereby preventing the drive assembly 300 from getting stuck, thereby preventing the rope from getting stuck in the winding drum 500 and making the rope unable to be loosened.

[0045] like Figure 3 As shown, the planetary gear 420 includes a first meshing portion 421 meshing with the fixed inner gear ring 440 and a second meshing portion 422 meshing with the movable inner gear ring 430 . The first meshing portion 421 is coaxially connected with the second meshing portion 422 , and the module of the first meshing portion 421 is greater than the module of the second meshing portion 422 .

[0046] Specifically, the movable inner ring gear 430 cooperates with the second meshing portion 422 with a smaller module, and the fixed inner ring gear 440 cooperates with the second meshing portion 422 with a larger module. Therefore, when the movable inner ring gear 430 rotates one tooth, it drives the planetary gear 420 to rotate one tooth, and the planetary gear 420 rotates according to the movable inner ring gear 430. If the fixed inner ring gear 440 wants to mesh with the planetary gear 420, it will move less in the ratio of 39 to 36. Since the position of the fixed inner ring gear 440 is fixed, the fixed inner ring gear 440 cannot be rotationally meshed with the planetary gear 420, thereby realizing the jamming function, making it impossible for the planetary gear 420 to transmit the force to the drive assembly 300 through the sun gear 410, thereby preventing the drive assembly 300 from getting stuck, thereby preventing the rope from getting stuck in the winding drum 500, and making the rope unable to be loosened.

[0047] like Figure 1 and Figure 2 As shown, a plurality of planetary gears 420 are provided; the lacing mechanism also includes a planetary fixing frame and planetary gear shafts 425 equal in number to the planetary gears 420, the plurality of planetary gears 420 are connected to the plurality of planetary gear shafts 425 in a one-to-one correspondence, and the plurality of planetary gear shafts 425 are all rotatably connected to the planetary fixing frame.

[0048] Specifically, the planetary gears 420 may be two, three or four. In this embodiment, three planetary gears 420 are provided. The planetary gears 420 are fixedly mounted on the inner circumference of the fixed inner gear ring 440 and the movable inner gear ring 430. Figure 1 and Figure 6 As shown, the planetary fixed frame includes an upper fixed frame 423 and a lower fixed frame 424, and the outer peripheral wall of the upper fixed frame 423 and the outer peripheral wall of the lower fixed frame 424 are both circular and have the same diameter. There are three planetary gear shafts 425, and three planetary gears 420 are fixedly sleeved on the three planetary gear shafts 425 in a one-to-one correspondence. The three planetary gear shafts 425 are respectively located at the three vertices of an equilateral triangle, and the two ends of each planetary gear shaft 425 are respectively rotatably connected to the upper fixed frame 423 and the lower fixed frame 424, and each planetary gear 420 has a partial meshing tooth located outside the planetary fixed frame for meshing with the fixed inner gear ring 440 and the movable inner gear ring 430. When the driving rope is tightened or loosened, the sun gear 410 drives the three planetary gears 420 to rotate at the same time, and the three planetary gears 420 cooperate to drive the movable inner ring gear 430 to rotate. In addition, the three planetary gear shafts 425 are respectively located at the three vertices of an equilateral triangle. Since the triangle has stability, the stability when driving the movable inner ring gear 430 can also be improved.

[0049] like Figure 2 As shown, the driving assembly 300 includes a motor 310, a worm 320 and a gear transmission assembly. The motor 310 is drivingly connected to the worm 320, and the gear transmission assembly is respectively meshed with the worm 320 and the sun gear 410.

[0050] Specifically, the motor 310, the worm 320 and the gear transmission assembly are all arranged on the side of the fixed inner gear ring 440 away from the movable inner gear ring 430, and the worm 320 is arranged in a direction perpendicular to the axis of the sun gear 410 and connected to the output shaft of the motor 310. The gear transmission assembly includes a primary transmission gear 331 and a secondary transmission gear 332 that mesh with each other, the primary transmission gear 331 meshes with the sun gear 410, and the secondary transmission gear 332 meshes with the worm 320.

[0051] When the winding drum 500 is driven to rotate, the motor 310 drives the worm 320 to rotate, and the worm 320 transmits power to the sun gear 410 through the mutually meshing primary transmission gear 331 and the secondary transmission gear 332, thereby realizing the rotation of the winding drum 500. The above-mentioned structure of the driving assembly 300 enables the motor 310 to transmit power to the sun gear 410 through the mutually meshing worm 320, the primary transmission gear 331, the secondary transmission gear 332 and the sun gear 410, thereby improving the precision of the movement.

The side of the main control circuit board 610 away from the human body monitoring film 910 is provided with a battery 200, and the battery 200 is electrically connected to the main control circuit board 610.

[0055] The waterproof cover 730 and one of the module upper cover 110 and the module lower cover 120 are integrally injection molded to improve the waterproofness between the locking button 710 and the releasing button 720 and the module housing.

[0056] A key light-transmitting plate 740 is also sleeved on the outside of the locking button 710 and the releasing button 720, a locking button light-guiding column 750 is also inserted in the middle of the locking button 710, and a releasing button light-guiding column 760 is also inserted in the middle of the releasing button 720.
