[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0025] Reference Figures 1 to 5 As shown, a day and night curtain motor of this embodiment includes a housing 1 and a bracket 2 disposed inside the housing 1. The housing 1 includes a shell and end caps located at both ends of the shell. The end caps are detachably connected to the shell, and a portion of the end cap extends into the shell to support the motor assembly.

[0026] Motor assemblies are symmetrically arranged at both ends of bracket 2. The output ends of the two motor assemblies face opposite directions. For day and night blinds, such as day and night honeycomb blinds, the day blind and night blind can be controlled separately or simultaneously.

[0027] At least one control board 4 is provided inside the housing 1. Preferably, one control board 4 is provided to control two motor assemblies, which is also convenient for installation.

[0028] The control board 4 is located on one side of the motor assembly. Preferably, the control board 4 is located above the motor assembly. A through hole is provided on the top of the housing 1 to facilitate the connection of an external power supply to the control board 4.

[0029] All motor components are electrically connected to the control board 4. The motor components include an output component 31, which extends to or out of the corresponding end of the housing 1. The output component 31 has an output hole, which is polygonal in shape to facilitate connection and realize power transmission.

[0030] Preferably, the end face of the output component 31 coincides with the end face of the housing 1, thereby reducing the overall length of the motor;

[0031] Combining the two motor assemblies together, compared to placing the two motor assemblies directly in the frame of the finished curtain, makes it easier to install the motors in the frame and ensures that the central axes of the output components 31 of the two motor assemblies coincide, preventing any deviation in the height position of the two output components 31, and also reducing the overall installation space occupied in the length direction.

[0032] Reference Figure 5 As shown, in a preferred embodiment, the bracket 2 is provided with a clearance groove 21, through which the control board 4 passes to prevent interference between the bracket 2 and the control board 4, and to facilitate the electrical connection between the motor 32 in the motor assembly and the control board 4.

[0033] The control plate 4 is inserted into the first positioning groove on both sides inside the end cap to form the installation positioning.

[0034] A second positioning groove is provided on each of the two opposite inner sidewalls of the clearance groove 21, and the control plate 4 passes through the second positioning groove.

[0035] Reference Figure 1 As shown, in another embodiment, two control boards 4 are provided. The two control boards 4 can be connected to a power source respectively, or the two control boards 4 can be electrically connected to a single power source.

[0036] Two control boards 4 are located on both sides of the bracket 2, and the motor assembly is electrically connected to the corresponding control board 4.

[0037] Reference Figure 5 As shown, the bracket 2 has circular grooves 22 on both sides opposite to each other. The circular grooves 22 are used to fit the motor 32 in the motor assembly, so that the tail of part of the motor 32 can be installed in the circular grooves 22 to form a positioning. The circular grooves 22 are connected to the clearance grooves 21 to facilitate the wiring between the tail of the motor 32 and the control board 4.

[0038] Multiple ribs 23 are formed on the inner wall of the circular groove 22. At least part of the motor assembly chamber is located in the circular groove 22 and abuts against the ribs 23. The ribs 23 play a positioning role, limiting the position of the motor 32 extending into the circular groove 22, preventing the motor 32 from extending too deep or too shallow into the circular groove 22, and also preventing the motor 32 from becoming loose, so that there is space between the tail of the motor 32 and the bracket 2.

[0039] Reference Figure 2 and Figure 3As shown, the motor assembly includes a motor 32, a reducer 33, and a clutch mechanism 34. The motor 32 is detachably connected to the bracket 2. The motor 32 is connected to the clutch mechanism 34 via the reducer 33. The output component 31 is connected to the output end of the clutch mechanism 34. Through the clutch mechanism 34, the manual and electric adjustment functions of the day and night curtain can be realized, thereby realizing the manual and electric lifting functions of the curtain.

[0040] Reference Figure 2 , Figure 3 As shown, the reducer 33 is a multi-stage planetary gear reducer, preferably a three-stage planetary gear reducer.

[0041] The clutch mechanism 34 includes a transmission component, an iron ring, and two magnetic beads. The output end of the reducer 33 is fixedly connected to the clutch component. The iron ring is fixedly connected to the end of the reducer 33. The magnetic beads are attracted to the iron ring and are located on opposite sides of the clutch component. The transmission component has a clutch cavity at the end facing the iron ring. The inner wall of the clutch cavity has two grooves that are adapted to the magnetic beads. The transmission component is connected to the output component 31.

[0042] Preferably, the output component 31 is integrally formed with the transmission component.

[0043] When the output end of the reducer 33 rotates, it will drive the clutch to rotate, and the clutch will push the magnetic bead to move, so that the magnetic bead is stuck between the groove and the clutch, which can synchronously drive the transmission component to rotate, realizing the power transmission of the motor 32 to the output component 31.

[0044] Conversely, when the output component 31 rotates, it will drive the transmission component to rotate. At this time, the clutch component does not rotate, the magnetic bead is attracted to the iron ring, and the power will not be transmitted to the reducer 33.

[0045] A magnetic ring 5 is fixedly connected to the output component 31. Two Hall sensors 41 are electrically connected to the corresponding magnetic ring 5 on the control board 4. When the output component 31 rotates, the magnetic ring 5 rotates synchronously. The rotation direction and rotation distance of the output component 31 are detected by the cooperation of the Hall sensors 41 and the magnetic ring 5.

[0046] Reference Figure 1 and Figure 4 As shown, the two ends of the outer casing 1 are detachably connected to pads 6. The pads 6 are used to raise the installation position of the motor. At least the outer part of the pads 6 is made of rubber, which can reduce the vibration of the motor.

[0047] The bottom of the pad 6 has a through groove 61. The through groove 61 facilitates the routing of the rope in the rope winder and prevents interference between the pad 6 and the rope.

[0048] A day / night blind, including the aforementioned day / night blind motor.

[0049] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
