The outer box 20 is connected to the guide rail 3, and the two sets of transmission components 21 are arranged at intervals in the outer box 20, and each set of transmission components 21 is correspondingly connected to a driving member 13, so that the transmission components 21 are driven and controlled by the driving member 13. The secondary transmission box 4 is connected to the other end of the guide rail 3, and the secondary transmission box 4 is in transmission connection with the two sets of transmission components 21 respectively.

[0038] In actual application scenarios, two curtain pieces are arranged in parallel and at intervals in the guide rail 3, and each curtain piece is individually controlled by a driving member 13 and a transmission assembly 21, and each curtain piece slides along the guide rail 3 under the cooperation of the driving member 13, the transmission assembly 21 and the auxiliary transmission box 4. When in use, one or two sets of driving members 13 can be controlled to operate according to the use requirements, so as to realize arbitrary driving of the two curtain pieces, which is convenient for users to adjust the light entering the window. It should be noted that the two curtain pieces can be made of the same material or different materials, and each curtain piece can be made of different materials according to the use requirements, such as gauze curtains, cloth curtains, blackout curtains, etc.

[0039] Furthermore, each driving member 13 includes a motor 131 and a reducer 132. The motor 131 is electrically connected to the controller 12 and is controlled by the controller 12. The reducer 132 is connected to the output end of the motor 131, and the reducer 132 is used to convert the high-speed rotation of the motor 131 into a low-speed output. The output end of the reducer 132 is connected to a transmission assembly 21. When running, the motor 131 is output after passing through the reducer 132, and then the reducer 132 drives the transmission assembly 21 to rotate.

[0040] Please refer to Figure 3 , Figure 3 Schematic diagram of the transmission assembly. Further, each transmission assembly 21 includes a first transmission wheel 211, a second transmission wheel 212 and a conveyor belt (not shown). The first transmission wheel 211 is connected to the output end of the driving member 13, and the first transmission wheel 211 is meshed with one end of the second transmission wheel 212. The other end of the second transmission wheel 212 is connected to the auxiliary transmission box 4 through a synchronous belt.

[0041] During operation, the driving end of the driving member 13 drives the first transmission wheel 211 to rotate, and at the same time, the first transmission wheel 211 drives the second transmission wheel 212 to rotate. Under the drive of the second transmission wheel 212, the conveyor belt is transmitted between the second transmission wheel 212 and the auxiliary transmission box 4. In the present embodiment, the first transmission wheel 211 is a "T" shaped gear, and the second transmission wheel 212 is a double-sided gear. The second transmission wheel 212 has a main transmission wheel 2121 and an auxiliary transmission wheel 2122, and the main transmission wheel 2121 is coaxially connected with the auxiliary transmission wheel 2122. The main transmission wheel 2121 is meshed with the first transmission wheel 211, and the auxiliary transmission wheel 2122 is connected with the conveyor belt. When the driving member 13 drives the first transmission wheel 211 to rotate, the first transmission wheel 211 drives the main transmission wheel 2121 to rotate, and the auxiliary transmission wheel 2122 follows the main transmission wheel 2121 to rotate coaxially, thereby driving the conveyor belt to rotate.

[0042] Please refer to Figure 4 , Figure 4It is an exploded view of the auxiliary transmission box. Further, the auxiliary transmission box 4 includes a box body 41 and two sets of transmission parts 42. Two accommodation positions 411 are formed in the box body 41, and the two accommodation positions 411 are arranged at intervals. One transmission part 42 is arranged in each accommodation position 411. The two transmission parts 42 are arranged corresponding to the two sets of transmission components 21, and each transmission part 42 is in transmission connection with a transmission component 21.

[0043] Specifically, the transmission part 42 includes a gear 421 and two bearings 422. The two bearings 422 are sleeved at both ends of the gear 421. During installation, the bearings 422 are clamped in the accommodation position 411, so that the gear 421 can rotate relative to the accommodation position 411, and the gear 421 is connected to the conveyor belt. When the driving part 13 drives the first transmission wheel 211 to rotate, the first transmission wheel 211 drives the second transmission wheel 212 to rotate, so that the conveyor belt is transmitted between the second transmission wheel 212 and the transmission part 42.

[0044] Further, the box body 41 includes a main body 412 and a clamping part 413. The accommodation position 411 is arranged in the main body 412, and the clamping part 413 protrudes from one side of the main body 412. During connection, the clamping part 413 is inserted into one end of the guide rail 3, so that the box body 41 is tightly connected to the guide rail 3.

[0045] Please refer to Figure 5 , Figure 5 It is a sectional view of the guide rail. Further, the guide rail 3 is formed with two sliding rails 31, and the two sliding rails 31 are arranged at intervals. One end of the two sliding rails 31 is connected to the main transmission box 2, and a transmission component 21 is arranged corresponding to one end of each sliding rail 31, and the transmission component 21 moves along the sliding rail 31. The other end of the sliding rail 31 is connected to the auxiliary transmission box 4.

[0046] In this embodiment, the two sets of transmission components 21 are arranged at intervals at one end of the two sliding rails 31, and each transmission component 21 corresponds to one sliding rail 31. The auxiliary transmission box 4 is arranged at the other end of the two sliding rails 31. The box body 41 is connected to the two sliding rails 31, and the two transmission parts 42 are respectively arranged corresponding to the two sliding rails 31, that is, each transmission part 42 corresponds to one sliding rail 31. During connection, the conveyor belt of the transmission component 21 passes through the sliding rail 31 and is connected to a transmission part 42, so that the conveyor belt is transmitted in one sliding rail 31. By arranging the two sets of sliding rails 31, the conveyor belts of the two components are spaced apart from each other, avoiding mutual interference between them during operation.

[0047] Further, the opposite inner sidewalls of each slide rail 31 extend inward to form a partition plate 311. The partition plate 311 divides the slide rail 31 vertically to form a first track 312 and a second track 313. The transmission assembly 21 corresponds to the first track 312. In this way, by providing the partition plate 311 on the inner sidewall of the slide rail 31, the space inside the slide rail 31 is effectively divided into multiple layers; and the width of the slide rail 31 is smaller, and multiple tracks can be provided under the condition of the same width to meet different usage requirements of users.

[0048] Please refer to Figure 1 and Figure 2 , furthermore, the double-rail electric curtain machine in this embodiment further includes a lighting member (not shown in the figure). A lamp slot 32 is formed between the two slide rails 31. The lighting member is disposed in the lamp slot 32 and is electrically connected to the controller 12. The controller 12 controls the lighting and extinguishing states of the lighting member, and the user can select the on / off state of the lighting member according to usage requirements. Preferably, in this embodiment, the lighting member is an LED light strip, which has the advantages of energy saving, adjustable brightness, adjustable light color, etc., so that the double-rail electric curtain machine can be applied to more different usage scenarios.

[0049] In addition, the double-rail electric curtain machine further includes a lamp cover 5, and the lamp cover 5 covers the lamp slot 32. During use, the lamp cover 5 can filter the strong light directly emitted by the lighting member, making the light soft and comfortable, and at the same time playing the roles of dust prevention and beautifying the double-rail electric curtain machine.

[0050] Please refer to Figure 1 , the double-rail electric curtain machine further includes two sets of sliding carts 6. The two sets of sliding carts 6 are respectively disposed in the two slide rails 31, and each set of sliding carts 6 is connected to a transmission assembly 21. During operation, the sliding cart 6 linearly moves along the slide rail 31 under the drive of the transmission assembly 21. In an actual application scenario, one end of the curtain piece is fixed to one end of the slide rail 31, and the other end is connected to the sliding cart 6. The sliding cart 6 drives the curtain piece to move, thereby realizing the automatic opening and closing of the curtain piece.

[0051] Please refer to Figure 6 and Figure 7 , Figure 6 is an exploded view of the sliding cart, Figure 7 is a cross-sectional view of the sliding cart in the guide rail. Specifically, each set of sliding carts 6 includes a connecting plate 61, a belt buckle 62, a hanging plate 63 and a pulley 64. The belt buckle 62, the hanging plate 63 and the pulley 64 are all disposed on the connecting plate 61. The belt buckle 62 is located in the first track 312 and is connected to the conveyor belt. The pulley 64 is located in the second track 313 and linearly moves along the second track 313.

[0052] In an actual application scenario, the hanging plate 63 is located outside the sliding rail 31 and is used for hanging curtain pieces. The belt buckle 62 is used to connect with the conveyor belt. During operation, the conveyor belt drives the belt buckle 62 to move along the first track 312, and the belt buckle 62 synchronously drives the connecting plate 61 and the hanging plate 63 to move, while the pulley 64 moves along the second track 313. When the sliding carriage 6 runs along the sliding rail 31, the conveyor belt and the pulley 64 can move in different tracks, avoiding interference between the two.

[0053] In summary, by setting two sets of driving components 13 and two sets of transmission components 21, each set of driving components 13 independently controls one transmission component 21, and the transmission component 21 is connected to the curtain piece. The curtain piece slides along the guide rail 3 under the cooperation of the driving component 13, the transmission component 21 and the auxiliary transmission box 4. During use, according to the user's usage requirements, one set of driving components 13 or two sets of driving components 13 can be controlled to operate, so as to realize arbitrary driving of the two curtain pieces, facilitating the user to adjust the light entering the window.
