[0027] Example 1

[0028] like Figure 1-5As shown, an electrically opened and closed ceiling curtain comprises a frame, a curtain body 5, a transmission assembly and a drive motor 6. The frame comprises a top beam 1, a bottom beam 2 and two side beams 3. The top of the curtain body 5 is connected to the top beam 1, and the bottom of the curtain body 5 is connected to a traction beam 4. The drive motor 6 is arranged in the traction beam 4. The drive motor 6 drives the traction beam 4 to move up and down along the side beams 3 through the transmission assembly. The transmission assembly comprises a transmission rod 8, a first belt 9a, a second belt 9b, a first transmission tooth 10a, a second transmission tooth 10b, a first slide 11a and a second slide 11b. The transmission rod 8 is arranged at the bottom of the curtain body 5. The traction beam 4 is in transmission connection with the drive motor 6, one end of the transmission rod 8 is connected to the first transmission tooth 10a, and the other end of the transmission rod 8 is connected to the second transmission tooth 10b. One end of the traction beam 4 is connected to the first slide 11a, and the other end of the traction beam 4 is connected to the second slide 11b. The first transmission tooth 10a is rotatably set in the first slide 11a, and the second transmission tooth 10b is rotatably set in the second slide 11b. The first belt 9a and the second belt 9b are respectively located in the two side beams 3. The first belt 9a passes through the first slide 11a and engages with the first transmission tooth 10a for transmission. The second belt 9b passes through the second slide 11b and engages with the second transmission tooth 10b for transmission. The curtain body 5 is a rolling curtain. The bottom of the rolling curtain is connected to the traction beam 4. The top of the rolling curtain is connected to a roller tube. A coil spring is provided in the roller tube. The roller tube is rotatably connected to the top beam 1. The transmission rod 8 is driven by the driving motor 6 to rotate. The transmission rod 8 drives the first transmission teeth 10a and the second transmission teeth 10b at both ends to rotate synchronously, so that the first transmission teeth 10a and the second transmission teeth 10b are respectively driven upward or downward along the first belt 9a and the second belt 9b, thereby causing the traction beam 4 to move along the two side beams 3 of the frame. The roller blinds are opened and closed by sliding up or down, and when the traction beam 4 slides downward, the roller tube on the top of the roller blinds rotates as the roller blinds unfold. At this time, the coil spring in the coil tube is wound up, and when the traction beam 4 slides upward, the reeling force of the coil spring drives the coil tube to reel in the roller blinds, thereby realizing the smooth opening and closing of the roller blinds, and also making it possible for the ceiling roller blinds to be installed on the top or facade of the building, with smooth electric opening and closing. The first belt 9a and the second belt 9b are both single belts, and the so-called single belts are non-closed strip belts. The first belt 9a and the second belt 9b are fixedly installed in the corresponding side beams 3, with a simple structure and lower cost.

[0029] The utility model installs the driving motor 6 on the traction beam 4, and the driving motor 6 rotates the transmission rod 8 to synchronously drive the first transmission teeth 10a and the second transmission teeth 10b on both sides to rotate up and down along the first belt 9a and the second belt 9b to realize the up and down sliding of the traction beam 4, thereby realizing the electric opening and closing of the ceiling curtain. The first belt 9a and the second belt 9b are fixed structures during the entire opening and closing process. The traction beam 4 can move up and down smoothly along the first belt 9a and the second belt 9b to ensure the smooth opening and closing of the ceiling curtain, and the problem of the traction beam 4 tilting left and right is not easy to occur. The overall structure is simple. The first belt 9a and the second belt 9b adopt a fixed installation structure, which is convenient for the traction beam 4 to be quickly and horizontally installed. During installation, the first belt 9a and the second belt 9b are fixed in the side beam 3, and then the first belt 9a and the second belt 9b are meshed with the corresponding first transmission teeth 10a and the second transmission teeth 10b and encapsulated in the corresponding first slide 11a and the second slide 11b, so that the traction beam 4 can be quickly and horizontally installed in the frame. The overall structure is convenient and fast to assemble and is not easy to rework, thereby improving work efficiency.

[0030] Among them, the traction beam 4 is provided with a solar panel 7 outside, and the solar panel 7 is electrically connected to the drive motor 6. By arranging the drive motor 6 and the solar panel 7 on the traction beam 4, on the one hand, it is convenient for the solar panel 7 to power the drive motor 6, and on the other hand, the solar panel 7 can flexibly change the lighting position as the traction beam 4 moves, thereby improving the charging effect. Moreover, the overall structure is simple and easy to assemble.

[0031] Among them, the side beam 3 is provided with a side rail 3.1 for installing the first belt 9a and the second belt 9b. The two ends of the first belt 9a and the second belt 9b are respectively fixed to the two ends of the corresponding side beam 3, and the first slide 11a and the second slide 11b are both slidably matched with the side rail 3.1.

[0032] Among them, the meshing position of the first belt 9a and the first transmission tooth 10a forms a downwardly concave U-shaped structure, and the meshing position of the second belt 9b and the second transmission tooth 10b forms a downwardly concave U-shaped structure. This structure can prevent the first transmission teeth 10a and the second transmission teeth 10b from slipping, ensuring that the first transmission teeth 10a and the second transmission teeth 10b can stably engage and transmit with the first belt 9a and the second belt 9b, so that the traction beam 4 can slide smoothly up and down along the side beam 3.

[0033] Among them, guide wheels 12 for supporting the first belt 9a are provided on both sides of the first transmission tooth 10a in the first slide 11a, and guide wheels 12 for supporting the second belt 9b are provided on both sides of the second transmission tooth 10b in the second slide 11b. The guide wheels 12 cooperate with the smooth surfaces of the corresponding first belt 9a and the second belt 9b. The guide wheels 12 can provide auxiliary support and anti-wear for the first belt 9a and the second belt 9b. Moreover, installing guide wheels 12 on both sides of the first transmission tooth 10a and the second transmission tooth 10b can better assist the first transmission tooth 10a and the second transmission tooth 10b in meshing transmission with the first belt 9a and the second belt 9b, increase the contact area of ​​the meshing transmission, prevent slipping, and improve the stability of the transmission.

[0034] The drive motor 6 is a single-output motor, which includes a motor 6.1, a battery 6.2, a control board 6.3, a first parallel gear 6.4, and a second parallel gear 6.5. The motor 6.1 and the battery 6.2 are electrically connected to the control board 6.3, and the control board 6.3 is electrically connected to the solar panel 7. The first parallel gear 6.4 is coaxially connected to the output end of the motor 6.1, the first parallel gear 6.4 is meshed with the second parallel gear 6.5 for transmission, and the second parallel gear 6.5 is coaxially connected to the transmission rod 8. Compared with the double-output The structure of the output motor transmission, the single output motor drives the transmission rod 8 so that the two ends of the transmission rod 8 have good synchronization, and will not produce deviations over time, thereby avoiding the problem of the traction beam 4 tilting left and right over time. Moreover, the single output motor transmits power to the transmission rod 8 in parallel through the first parallel gear 6.4 and the second parallel gear 6.5. Compared with the traditional structure in which the single output motor can only be installed with the end of the transmission rod, the installation position of the above structure is more flexible, so that the two ends of the transmission rod 8 can be left empty to install the first transmission teeth 10a and the second transmission teeth 10b, and it has good synchronization.

[0035] When in use, the ceiling curtain can be installed on the top surface or facade of the building, and the solar panel 7 supplies power to the driving motor 6. The driving motor 6 drives the transmission rod 8 to rotate, and the transmission rod 8 drives the first transmission teeth 10a and the second transmission teeth 10b at both ends to rotate synchronously, so that the first transmission teeth 10a and the second transmission teeth 10b are respectively transmitted upward or downward along the first belt 9a and the second belt 9b, so that the traction beam 4 slides upward or downward along the two side beams 3 of the frame to realize the opening and closing of the roller curtain, and when the traction beam 4 slides downward, the roller tube at the top of the roller curtain rotates as the roller curtain unfolds. At this time, the coil spring in the coil tube is rolled up, and when the traction beam 4 slides upward, the winding force of the coil spring drives the coil tube to retract. The roller shutter can be opened and closed smoothly, and the whole process is electrically controlled, which is convenient and labor-saving to operate. The first belt 9a and the second belt 9b are fixed structures during the whole opening and closing process, and the traction beam 4 can move up and down smoothly along the first belt 9a and the second belt 9b to ensure the smooth opening and closing of the roller shutter, and the problem of the traction beam 4 tilting left and right is not easy to occur. The overall structure is simple, and the first belt 9a and the second belt 9b adopt a fixed installation structure, which is convenient for the rapid horizontal installation of the traction beam 4. The overall structure is easy and fast to assemble and is not easy to rework, thereby improving work efficiency. Moreover, the solar panel 7 is installed on the traction beam 4, and the lighting position can be adjusted as the traction beam 4 moves, so as to realize flexible lighting of the solar panel 7 and improve the charging effect.

A pull rope 13 is passed through the honeycomb curtain, and two pull ropes 13 are symmetrically arranged in a group. One end of the pull rope 13 is fixed to the bottom of the honeycomb curtain, and the other end of the pull rope 13 passes through the honeycomb curtain to the top beam 1 and extends to the bottom of the corresponding side beam 3 and then fixedly connected upward to the corresponding first slide 11a and second slide 11b.
