Detailed Implementation

[0032] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown in the figure, the electric curtain drive device of this embodiment includes a track 1, a trolley 2, and a drive module 3; a main transmission box 4 and a secondary transmission box 5 are respectively installed at both ends of the track 1; a toothed belt is threaded through the track 1, and the toothed belt is wound around the gear set 6 of the main transmission box 4 and the secondary transmission gear of the secondary transmission box 5 to form a closed loop; the trolley 2 is slidably installed in the track 1, and the trolley 2 is connected to the toothed belt; the drive module 3 is detachably connected to the main transmission box 4, and the drive module 3 can drive the gear set 6 to drive the toothed belt transmission; the detachable connection structure 7 between the drive module 3 and the main transmission box 4 includes an insertion slot 71, a sliding seat 72, a spring 73, and a snap-fit ​​hole 74; wherein:

[0033] The insertion slot 71 is provided on the main transmission box 4. The cross-section of the insertion slot 71 is a non-circular structure. The depth direction of the insertion slot 71 and the length direction of the track 1 are both set along the left and right directions. The slot opening of the insertion slot 71 faces the direction of the auxiliary transmission box 5.

[0034] The sliding seat 72 is slidably installed in the main transmission box 4. The sliding seat 72 is provided with a claw part 721 that extends into the insertion groove 71 and a pressing part 722 that protrudes from the bottom surface of the main transmission box 4.

[0035] The spring 73 is installed inside the main transmission box 4. The spring 73 acts on the sliding seat 72 so that the sliding seat 72 maintains a downward movement tendency.

[0036] One end of the drive module 3 is a plug-in end, and the snap-fit ​​hole 74 is provided on the end face of the plug-in end;

[0037] When the plug end of the drive module 3 is inserted into the insertion slot 71, the sliding seat 72, under the action of the spring 73, causes the claw part 721 to engage with the buckle hole 74, thereby connecting the drive module 3 with the main transmission box 4. When disassembling, simply press the pressing part 722 on the sliding seat 72 to drive it upward, so that the claw part 721 is disengaged from the buckle hole 74, and the drive module 3 can be directly pulled out.

[0038] To ensure that the pressing part 722 of the sliding seat 72 is not pressed when the drive module 3 is connected to the main transmission box 4, the claw part 721 can also be aligned with the buckle hole 74, such as Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, a pushing slope 723 is formed on the claw portion 721 of the sliding seat 72; the pushing slope 723 is located on the bottom surface of the claw portion 721, and the pushing slope 723 gradually slopes downward from the end face of the claw portion 721 towards the sliding seat 72.

With this design, when the plug-in end of the drive module 3 is inserted into the insertion slot 71, the lower edge of the latching hole 74 of the plug-in end of the drive module 3 will push the pushing slope 723 of the claw portion 721, causing the sliding seat 72 to move upward. As the plug-in end of the drive module 3 gradually enters the insertion slot 71, the claw portion 721 gradually enters the latching hole 74 of the plug-in end of the drive module 3 and finally engages with the latching hole 74.

The electric curtain drive device according to claim 3, characterized in that: The end face of the plug-in terminal is also provided with a transmission through hole; the drive module is provided with a drive circuit board, a motor and a gearbox; the drive circuit board, the motor and the gearbox are arranged in sequence along the left and right direction; the input shaft of the gearbox is coaxially rotatably connected to the rotating shaft of the motor, and the output shaft of the gearbox is directly opposite the transmission through hole; the pin header and the motor are electrically connected to the drive circuit board; the gear set of the main transmission box is provided with a transmission connection end located in the insertion slot; when the plug-in terminal of the drive module is inserted into the insertion slot, the transmission connection end of the gear set passes through the transmission through hole and is coaxially rotatably connected to the output shaft of the gearbox.

8. The electric curtain drive device according to claim 7, characterized in that: The main transmission box includes a housing, a mounting plate, a cover, and a partition. The housing has an insertion cavity and a mounting cavity. The insertion cavity is positioned along the left-right direction in its depth direction, with its opening facing the direction of the auxiliary transmission box. The mounting cavity has its opening facing upwards. The mounting plate is fixed inside the insertion cavity, dividing it into a sliding space and an insertion slot. A sliding seat is slidably mounted in the sliding space, and the mounting plate has sliding holes for the claws to extend into the insertion slot and slide up and down. A spring is compressed between the top surface of the sliding seat and the inner top surface of the sliding space. The partition is installed inside the mounting cavity, forming a transmission space between the partition and the bottom of the mounting cavity. The gear set is installed in the transmission space. The transmission connection end of the gear set extends through the sliding space into the insertion slot. The cover closes onto the opening of the mounting cavity, forming a wiring channel between the cover and the partition. One end of the wiring channel communicates with the insertion slot through the sliding space.
