[0002] With the rapid development of automated equipment and smart homes, bin drive assemblies, as the core component for automatic lid opening and closing, are widely used in smart trash cans, industrial storage bins, and other fields. However, existing bin drive assemblies have several shortcomings.

Second, the transmission mechanism mostly adopts an integrated shell design, which leads to difficulties in assembly and subsequent maintenance; the layout of the gear set and motor is unreasonable, resulting in low transmission efficiency and large space occupation.

The connecting sleeve 521 is axially fitted onto the synchronous rotation section 513, forming a circumferential limit to achieve synchronous rotation of the pivot body 51 and the bucket lid.

Each component operates stably within its independent cavity, without interfering with each other, thus improving the reliability and service life of the entire system.

[0067] In this embodiment, the assembly housing includes a mounting base 1 and a first side cover 21 and a second side cover 22 detachably mounted on both sides of the mounting base 1, as well as a bottom cover 23.

The detachable connections mentioned above include, but are not limited to, snap-fit ​​connections, screw connections, or magnetic connections. The layered layout design makes full use of space, organically integrating the motor 3, transmission mechanism, power supply component 6, etc., effectively reducing the overall volume of the drive assembly, improving the integration, and creating favorable conditions for the miniaturization design of the equipment.

[0068] In this embodiment, the drive cavity 14 is divided into a first drive cavity 141 and a second drive cavity 142 by a partition 143. The output shaft 31 of the motor 3 is adapted to pass through the partition 143 and connect to the transmission mechanism. The first drive cavity 141 includes a first drive cavity opening 1411 for the transmission mechanism to enter, and the second drive cavity 142 includes a second drive cavity opening 1421 for the motor 3 to enter. The first drive cavity opening 1411 and the second drive cavity opening 1421 are far apart from each other and are both arranged perpendicular to the drive shaft direction of the motor 3. The first side cover 21 is adapted to fasten and close the first drive cavity 141 along the axial direction of the output shaft 31 of the motor 3, and the second side cover 22 is adapted to fasten and close the second drive cavity 142 along the axial direction of the output shaft 31 of the motor 3.

[0069] In this embodiment, the transmission mechanism includes an input gear 45, a gear set 40, and an output gear 46 connected in sequence. The input gear 45 is connected to the output shaft 31 of the motor 3, and the output gear 46 is coaxially mounted on the first pivot section 511. The output gear 46 includes an arc-shaped rack with an arcuate radius.

The third gear set 43 includes a third rotating shaft 431 and a third transmission gear 432 pivotally connected to the third rotating shaft 431. The fourth gear set 44 includes a fourth rotating shaft 441 and a fourth transmission gear 442 pivotally connected to the fourth rotating shaft 441. An input gear in one of the first coaxial gear pairs 412 is adapted to connect to an input gear 45, and output gears in the other first coaxial gear pairs 412 are adapted to connect to input gears in the second coaxial gear pairs 422. The output gear in the second coaxial gear pair 422 is adapted to mesh with the third transmission gear 432, while the output gears in other second coaxial gear pairs 422 are adapted to connect with the input gears in the first coaxial gear pair 412.

The input gear in the first coaxial gear pair 412 has a larger radial dimension than its output gear, and the input gear in the second coaxial gear pair 422 also has a larger radial dimension than its output gear, thereby amplifying the torque for lifting or pulling the bucket lid. The first rotating shaft 411, the second rotating shaft 421, the third rotating shaft 431, and the fourth rotating shaft 441 are all arranged parallel to the output shaft 31 of the motor 3, and are arranged sequentially from top to bottom. This staggered layout of four-stage gear sets achieves a high reduction ratio transmission within a limited space, optimizes the transmission path, and improves transmission efficiency. The first side cover 21 is adapted to cooperate with the fixed base 1 to support the first rotating shaft 411, the second rotating shaft 421, the third rotating shaft 431 and the fourth rotating shaft 441.

[0071] During installation, the first rotating shaft 411, the second rotating shaft 421, the third rotating shaft 431, and the fourth rotating shaft 441 can be installed on the fixed base 1 first. The pre-set mounting structure on the fixed base 1 is used to initially fix the position of the rotating shafts, and then the other components of the gear set are installed. After the gear set 40 is assembled, the first side cover 21 is installed. The first side cover 21 cooperates with the fixed base 1 to further fix the rotating shafts, completing the installation of the entire gear set.

The first ear seat 11 forms a first ear seat cavity 111, which communicates with the first drive cavity 141. The first ear seat cavity 111 is adapted to provide space for the output gear 46 to mesh with the fourth transmission gear 442. When the drive assembly is working, that is, when the lid is lifted, the torsion spring 514 is in a compressed state, which generates a rebound force to offset part of the weight of the lid, so that the motor 3 can drive a large load even with a low power.

[0073] In this embodiment, the first pivot segment 511 includes a first positioning surface 5111 and a second positioning surface 51112 arranged radially therein. A stop block 112 is provided in the first ear seat cavity. The stop block 112 includes a first stop surface 1121 and a second stop surface 1122.

[0074] In this embodiment, the drive assembly further includes an opening / closing detection device, which includes a sensing magnet 73, a first Hall element 71, and a second Hall element. The first Hall element 71 is electrically connected to the Hall element control circuit board 74, and is respectively disposed on the rotation path of the sensing magnet 73. When the first Hall element 71 rotates to align with the sensing magnet 73, the control circuit is adapted to receive an open / closed signal, thereby controlling the motor to stop working. The second Hall element is disposed at the front end of the lid, and the corresponding sensing magnet is disposed on the upper edge of the bucket. When the second Hall element rotates to align with the sensing magnet, the control circuit is adapted to receive a closed signal, thereby controlling the motor to stop working. The open / closed state is detected non-contactly through magnetic induction, avoiding mechanical limit wear.

[0075] In this embodiment, the second earpiece 12 includes a first earpiece body 121 and an extension 122.

The inner insertion portion 1221 is inserted into the first earpiece body 121 and supports the second pivot segment 512. The sensing magnet 73 is installed on the second pivot segment 512 and extends into the first earpiece cavity 1223. The Hall element control circuit board 74, the first Hall element 71, and the second Hall element 72 are disposed in the first earpiece cavity 1223. The first side cover 21 is adapted to simultaneously close the first earpiece cavity 111. The first side cover 21, in conjunction with the first earpiece 11, is adapted to axially limit the first pivot segment 511. The second side cover 22 is adapted to simultaneously seal the ear seat cavity. Specifically, the second side cover 22 and the extension 1222 are detachably coupled to improve assembly efficiency.

[0076] In this embodiment, the power supply cavity is connected to the second drive cavity 142 for electrical connection between the control circuit board 62 and the motor 3. An extension cavity is located adjacent to the second drive cavity, and the extension cavity and the second drive cavity 142 provide an electrical connection between the opening / closing detection device and the control circuit board 62. This reduces the complexity of the wiring layout, confines the wiring within the housing assembly, ensures the stability of signal and power transmission between components, and improves the overall integrity of the drive assembly. The power supply cover includes several wiring ports suitable for connecting to the power supply cavity.
