[0026] Example

[0027] In current split-type curtain drive mechanisms, regardless of whether the drive box 2 and motor box 1 are assembled using a side-insertion fixation or a screw-lock, the motor box 1 ultimately rests flat against the surface of the drive box 2. The stability of the assembly between the motor box 1 and drive box 2 depends entirely on the impact resistance of the latch and locking plate. Especially under lateral impact, the motor box 1 is prone to detachment due to breakage of the locking plate or latch. Based on the traditional electric curtain drive mechanism, we have improved the design to create a locking and fixing mechanism that integrates insertion, extraction, and screwing between the motor box 1 and drive box 2. This retains the traditional screw-lock fixing method while improving the lateral impact resistance of the assembly connection structure between the motor box 1 and drive box 2. This effectively prevents the latch and locking plate from being damaged and detached due to excessive impact force when the motor box 1 is subjected to lateral impact. The specific solution is as follows:

[0028] like Figures 1-2As shown, this embodiment provides an electric curtain drive mechanism, specifically including a motor box 1 and a drive box 2. The motor box 1 includes a main box body 101, a bottom cover 102, and a top cover 103. The drive box 2 includes an assembly box 201 and a sealing cover 211. The sealing cover 211 is fastened to the top of the assembly box 201. The front end of the assembly box 201 has an integrally formed track insertion part 202. The bottom of the track insertion part 202 has a positioning slot that cooperates with the locking component 107. The top cover 103 and the bottom cover 102 are respectively installed at both ends of the main box body 101. 3. One end of the top cover 103 has a protruding motor mounting slot 105 for mounting the drive motor 106, and the other end of the top cover 103 has a locking component 107. The outer side of the motor mounting slot 105 facing the locking component 107 has an integrally formed quick-connect angle positioning part 110. The middle position of the quick-connect angle positioning part 110 and the outer surface of the motor mounting slot 105 on both sides of the quick-connect angle positioning part 110 are integrally formed with anti-loosening locking pieces 111. In order to match the design of the motor mounting slot 105 on the motor box 1 and realize the socket screwing lock, the bottom of its assembly box 201 is integrally formed with The assembly groove 203 is formed to fit the motor mounting groove 105; a quick-connect angle positioning groove 204 is integrally formed on the inner side of the assembly groove 203 near the rail insertion part 202; a clearance groove 205 is integrally formed around the outer circumference of the inner side of the quick-connect angle positioning groove 204; clearance notches 206 are provided on the groove edge of the assembly groove 203 for the anti-disengagement locking piece 111 to enter the clearance groove 205; anti-disengagement locking claws 207 are located between two adjacent clearance notches 206; there are 2-3 anti-disengagement locking pieces 111 on each side of the quick-connect angle positioning part 110. The anti-disengagement locking plates 111 on both sides of the quick-connect angle positioning part 110 are symmetrically designed with the anti-disengagement locking plate 111 in the middle of the quick-connect angle positioning part 110 as the center. The width of the quick-connect angle positioning part 110 is half the width of the quick-connect angle positioning groove 204. In this design, both sides of the anti-disengagement locking claw 207 are provided with clearance notches 206 for the anti-disengagement locking plate 111 to pass through. This allows the motor box 1 to no longer be limited to unilateral rotation assembly when it is assembled with the drive box 2. Combined with the cooperation of the locking component 107 and the positioning slot, bidirectional screw-locking positioning can be achieved.

[0029] like Figure 3As shown, the locking assembly 107 includes a slot 171 integrally formed on the back of the top cover 103. A locking pin 172 is slidably inserted into the inner side of the slot 171. The bottom end of the locking pin 172 slides through the top cover 103. A lever 173 is integrally formed in the middle of the locking pin 172 via a transverse connecting bridge. A stop block is provided at the top of the slot 171. A spring 174 is provided between the connecting bridge and the stop block. The width of the locking pin 172 is adapted to the width of the positioning slot. In the structural design of the locking assembly 107, the force of the spring 174 ensures that the locking pin 172 is always in an extended state without external force, ensuring the stability of the motor box 1 and the drive box 2 after assembly and preventing the motor box 1 from accidentally detaching from the drive box 2. It should be further noted that the locking pin 172... The width is two-thirds of the quick-connect angle positioning groove 204, and the quick-connect angle positioning part 110 can rotate 30 degrees within the quick-connect angle positioning groove 204. Both the positioning slot and the quick-connect angle positioning groove 204 are located on the central axis of the motor box 1. In this design, the motor mounting slot 105 on the motor box 1 can be inserted into the assembly slot 203 regardless of whether it is deflected to the left or right. Due to the limitation of the deflection angle of the quick-connect angle positioning part 110 in the quick-connect angle positioning groove 204, and the design of the width of the locking pin 172, one side of the locking pin 172 can abut against the bottom of the drive box 2. This means that the drive box 2 does not need to be manually manipulated during installation, making the assembly and combination operation between the drive box 2 and the motor box 1 more convenient.

[0030] In addition, when assembling the motor box 1 and the drive box 2, the motor mounting slot 105 and the assembly slot 203 are designed with a socket, which can effectively reduce the side impact force on the anti-disengagement locking plate 111 and the anti-disengagement locking claw 207, thereby improving the stability of the assembly between the motor box 1 and the drive box 2.

[0031] The assembly box 201 also has an integrally formed pulley mounting groove 208 inside. On the inner side of the cover 211, corresponding to the center of the assembly groove 203 and the center of the pulley mounting groove 208, a positioning post 212 is integrally formed. A driving wheel 210 and a driven wheel 209 are respectively rotatably mounted on the two positioning posts 212. The driven wheel 209 includes an integrally formed driven gear 291 and a belt-driven gear 292. The driven gear 291 and the belt-driven gear 292 are coaxially designed and driven by a belt. Gear 292 is located in pulley mounting groove 208; drive wheel 210 includes drive gear 2102 and splined insert 2101 integrally formed together. Drive gear 2102 and splined insert 2101 are coaxially designed. Drive gear 2102 and driven gear 291 mesh with each other. A hole for splined insert 2101 to pass through is opened at the center of mounting groove 203. The output shaft of drive motor 106 is equipped with a socket drive wheel 109 for plugging and mating with splined insert 2101.

[0032] The main housing 101 also houses an integrated circuit board 104 electrically connected to the drive motor 106. The integrated circuit board 104 has a quick-connect power connector, a light strip power supply connector, and a power supply control module. The power supply control module on the integrated circuit board 104 is electrically connected to a wireless communication module 108. The wireless communication module 108 can be any of the following: Bluetooth communication module, infrared wireless communication module, or WIFI communication module, which enables the electric curtain to be controlled remotely, providing convenience for the use of the curtain. The light strip power supply connector is designed on the integrated circuit to provide power to the light strip 4 on the electric curtain.

[0033] A type of electric curtain, such as Figure 4 As shown, it includes a slide rail 3, several sliding trolleys 6 and a traction bracket 7 slidably installed inside the slide rail 3, and the aforementioned electric curtain drive mechanism; the track insertion part 202 on the electric curtain drive mechanism is inserted into one end of the slide rail 3, while the other end of the slide rail 3 is equipped with a driven box 5 that works in conjunction with the electric curtain drive mechanism.

[0034] A light strip 4 is also installed on the side of the slide rail 3. One end of the light strip 4 is provided with a quick-connect wire for connecting to the light strip power supply connector on the integrated circuit board 104. It can be powered by the light strip power supply connector in the electric curtain drive mechanism.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
