[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 The present invention provides a technical solution: an intelligent curtain drive device, including a mounting wall 1, a curtain unfolding mechanism 2 provided on one side surface of the mounting wall 1, and a curtain mounting mechanism 3 provided on one side surface of the curtain unfolding mechanism 2.

[0023] The curtain unfolding mechanism 2 includes a mounting base 201, which is fixedly connected to one side surface of the mounting wall 1. A drive motor 202 is provided on the inner wall surface of the mounting base 201. A drive screw 203 is fixedly connected to the output end of the drive motor 202. A drive slider 204 is threadedly connected to the outer surface of the drive screw 203. A mounting slider 205 is fixedly connected to the side surface of the drive slider 204 away from the drive screw 203. A mounting rod 206 is slidably connected to the inner wall surface of the mounting slider 205. An anti-collision pad 207 is fixedly connected to the outer surface of the mounting slider 205. A mounting strip 208 is fixedly connected to one side surface of the mounting slide rod 206. Through the setting of the curtain unfolding mechanism 2, when in use, the drive motor 202 is energized to drive the drive screw 203 to rotate. The drive screw 203 drives the drive slider 204 to move linearly through the thread. The drive slider 204 drives the mounting slider 205 to slide along the mounting slide rod 206. The mounting slider 205 drives the curtain fabric 306 to unfold or retract through the curtain mounting mechanism 3. The drive motor 202 realizes the automatic opening and closing of the curtain fabric 306 through the transmission of the drive screw 203 and the drive slider 204, which improves the convenience of use.

[0024] Furthermore, the curtain mounting mechanism 3 includes a mounting groove 301, which is disposed on one side surface of the mounting slider 205. A limit spring 302 is fixedly connected to the inner wall surface of the mounting groove 301. A mounting female part 303 is attached to one side surface of the limit spring 302, and a mounting male part 304 is attached to one side surface of the mounting female part 303. A release linkage 305 is fixedly connected to one side surface of the mounting female part 303. A curtain fabric 306 is fixedly connected to the bottom end of the mounting male part 304. A linkage rod 307 is rotatably connected to one side surface of the release linkage 305, and a linkage turntable is rotatably connected to one side surface of the linkage rod 307. 308. A release knob 309 is fixedly connected to one side surface of the linkage turntable 308. Through the setting of the curtain installation mechanism 3, when in use, rotating the release knob 309 drives the linkage turntable 308 to rotate. The linkage turntable 308 pulls the release link 305 through the linkage rod 307. The release link 305 pushes the mounting female part 303 to compress the limit spring 302, so that the mounting female part 303 and the mounting male part 304 are separated, realizing the disassembly of the curtain fabric 306. Rotating the release knob 309 can realize the separation or locking of the mounting female part 303 and the mounting male part 304 without the need for tools, which is convenient for the disassembly, cleaning and replacement of the curtain fabric 306.

[0025] Furthermore, two sets of drive screws 203 and drive sliders 204 are symmetrically arranged on one side surface of drive motor 202. Drive motor 202 is slidably connected to one side surface of drive slider 204 through drive screw 203. With the arrangement of drive screws 203 and drive sliders 204, the two sets of drive screws 203 and drive sliders 204 are synchronously driven during use, so that the curtain fabric 306 is evenly stressed, avoiding jamming or displacement caused by unilateral stress, and improving the stability and smoothness of curtain opening and closing.

[0026] Furthermore, eight sets of mounting strips 208 are provided on one side surface of the mounting wall 1. The drive screw 203 is rotatably connected to one side surface of the mounting wall 1 through four sets of mounting strips 208. The mounting slide rod 206 is fixedly connected to one side surface of the mounting wall 1 through four sets of mounting strips 208. With the installation of mounting strips 208, in use, the four sets of mounting strips 208 support the drive screw 203 and fix the mounting slide rod 206, forming a stable frame structure. This ensures that the drive screw 203 rotates smoothly and the mounting slide rod 206 has high straightness, thus improving the motion accuracy and stability of the curtain unfolding mechanism 2.

[0027] Furthermore, a release groove is provided on the side surface of the mounting slider 205 near the release link 305, and the release link 305 slides along the inner wall of the mounting slider 205 through the release groove. By providing the release groove on the mounting slider 205, the release link 305 can slide precisely along the release groove during use, providing guidance for the linkage operation when removing the curtain fabric 306, ensuring the stability of the movement trajectory of the release link 305, avoiding deviation and jamming, and improving the operational reliability of the curtain installation mechanism 3.

[0028] Furthermore, two sets of limiting springs 302 and mounting female parts 303 are symmetrically arranged on one side surface of the mounting groove 301. The mounting female part 303 is attached to one side surface of the mounting male part 304 through the limiting springs 302. Through the setting of the limiting springs 302 and mounting female parts 303, the two sets of limiting springs 302 provide uniform elastic force during use, so that the mounting female part 303 and the mounting male part 304 are tightly attached, ensuring that the curtain fabric 306 is firmly installed. At the same time, the symmetrical structure can balance the force, avoid one side loosening or falling off, and improve the stability and reliability of the curtain installation.

[0029] Furthermore, two sets of linkage rods 307 are symmetrically arranged around the center of one side surface of the linkage turntable 308. The release knob 309 is rotatably connected to one side surface of the mounting slider 205 through the linkage turntable 308. With the linkage rods 307 in use, rotating the release knob 309 drives the linkage turntable 308 to rotate. The two sets of symmetrical linkage rods 307 simultaneously pull the release linkage rod 305, so that the force on both sides of the mounting mother part 303 is balanced. This ensures that the linkage mechanism operates smoothly when the curtain fabric 306 is removed, avoids jamming or damage caused by force on one side, and improves the smoothness of operation and the durability of the mechanism.

[0030] Working Principle: When the equipment starts running, the external power supply powers the entire system. The drive motor 202 is energized and starts, driving the drive screw 203 to rotate. Since the drive screw 203 and the drive slider 204 are connected by threads, the rotational motion of the drive screw 203 is converted into the linear motion of the drive slider 204. The drive slider 204 drives the mounting slider 205 to slide along the mounting rod 206. The mounting slider 205 is connected to the curtain fabric 306 through the curtain mounting mechanism 3, thereby pushing the curtain fabric 306 to unfold or retract. During the movement of the curtain fabric 306, the anti-collision pads 207 on the outside of the mounting slider 205 can buffer when the slider moves to the extreme positions at both ends, avoiding hard collisions. The mounting strips 208 fix the mounting rod 206 and the drive screw 203. The eight sets of mounting strips 208 form a stable support structure, ensuring the coaxiality of the drive screw 203 and the straightness of the mounting rod 206 when rotating, improving the smoothness of the movement. When it is necessary to remove the curtain fabric 306, turn the release knob 309. 9 drives the linkage turntable 308 to rotate. The linkage turntable 308 pulls the release link 305 through two sets of centrally symmetrical linkage rods 307. The release link 305 slides along the release groove of the mounting slider 205, pushing the mounting female part 303 to compress the limit spring 302, so that the mounting female part 303 separates from the mounting male part 304. At this time, the mounting male part 304 and the connected curtain fabric 306 can be directly removed to complete the disassembly. When installing the curtain fabric 306, align the mounting male part 304 with the mounting female part 303 and release the release link. The knob 309 and the spring force of the limiting spring 302 push the mounting female part 303 to reset, so that it fits tightly and locks with the mounting male part 304. The two sets of symmetrically arranged limiting springs 302 provide uniform clamping force to ensure that the curtain fabric 306 is stably suspended. Through the transmission of the drive screw 203 and the slider, the locking of the spring limiting mechanism and the unlocking of the knob linkage mechanism, the device realizes the automatic opening and closing control of the curtain and the tool-free quick disassembly and assembly of the curtain surface. This completes the use process of an intelligent curtain drive device.
