[0026] 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.

[0027] Reference Figures 1 to 9 As shown, a day and night curtain motor of this embodiment includes a housing 1, and a rubber sleeve is provided on the housing 1 to reduce vibration.

[0028] The housing 1 has a first cavity and a second cavity 2 that are horizontally arranged and interconnected. The first cavity has at least one set of transmission cavity groups 3. The transmission cavity group 3 includes an upper cavity 31 and a lower cavity 32 that are arranged vertically and interconnected. The upper cavity 31 is used to install a motor 5. The tail end of the motor 5 can extend into the second cavity 2. The control board assembly is installed in the second cavity 2. The tail end of the motor 5 can be fixedly connected to a magnetic ring. Two Hall sensors are electrically connected to the control board assembly. The rotation direction and rotation stroke of the motor 5 are detected by the cooperation of the Hall sensors and the magnetic ring.

[0029] Both ends of the lower cavity 32 penetrate the housing 1 to form a first through hole and a second through hole. The first through hole communicates with the first cavity and the second through hole communicates with the second cavity 2. The lower cavity 32 is used to install a transmission rod. The transmission rod has a polygonal cross-section to facilitate the rotation of the rope winder. Preferably, the transmission rod is a four-cornered rod.

[0030] The two ends of the transmission rod extend into corresponding first through holes and corresponding second through holes, which are respectively connected to the rope winder.

[0031] The aforementioned housing 1 structure provides installation space for the control board assembly, motor 5, and transmission rod, and distinguishes and positions the motor 5 and transmission rod vertically, facilitating the transmission connection between the motor 5 and the transmission rod. The motor 5 is installed through the upper cavity 31, eliminating the need for a motor 5 bracket, reducing the number of parts, and making installation more convenient.

[0032] In addition, the length of the support section for the transmission rod has been increased, and the support is provided through the first and second through holes to prevent a height difference between the two ends of the transmission rod.

[0033] Reference Figure 2 , Figure 3 and Figure 6 As shown, the second cavity 2 is provided with an extension section 4 to connect the lower cavity 32 and the second through hole. When the transmission rod is installed later, the transmission rod can be inserted along the extension section 4 through the extension section 4, which improves the installation efficiency.

[0034] In this embodiment, the bottom surface of the extension section 4 is provided with an arc-shaped groove, which on the one hand avoids the transmission rod, and on the other hand guides the insertion of the transmission rod;

[0035] Alternatively, the control panel can be mounted above extension 4, isolated from the drive rod located below.

[0036] Reference Figure 2 As shown, the housing 1 includes a left housing 11 and a right housing 12. A first cavity is formed inside the left housing 11 and a second cavity 2 is formed inside the right housing 12. The left housing 11 and the right housing 12 can be detachably connected.

[0037] Reference Figure 1 , Figure 3 and Figure 4 As shown, in a preferred embodiment, the right shell 12 includes an inner shell 121 and an outer shell 122. The inner shell 121 is integrally formed with the left shell 11, so that the second cavity 2 includes at least an upper opening and a lower opening, which facilitates the vertical installation of the control board. When inspecting the control board, only the outer shell 122 needs to be removed, and the left shell 11 is not affected, which is more convenient. The outer shell 122 is detachably connected to the left shell 11 or the inner shell 121 to close the upper opening and the lower opening. In this embodiment, the left shell 11 and the outer shell 122 are detachably connected. Multiple threaded holes are opened on the left shell 11, and multiple countersunk holes corresponding to the threaded holes are opened on the outer shell 122. The two are connected by screws.

[0038] In this embodiment, the extension 4 is integrally formed with the inner shell 121, which increases the stability of the connection between the inner shell 121 and the left shell 11, and also increases the stability of the extension 4.

[0039] Reference Figure 4As shown, the cross-section of the outer shell 122 is U-shaped. Preferably, the threaded holes are opened on the top and bottom surfaces of the left shell 11. Only two threaded hole positions are needed to connect the outer shell 122 and the left shell 11.

[0040] In this embodiment, the outer shell 122 is integrally formed with a cover at the end opposite to the left shell 11, which can prevent gaps from appearing between the outer shell 122 and the inner shell 121 at the connection point at the end opposite to the left shell 11.

[0041] On the other hand, when installing the outer casing 122, the inner wall of the cover can abut against the end of the inner casing 121 that is away from the left casing 11, thus positioning the outer casing 122 for installation.

[0042] Reference Figure 5 and Figure 6 As shown, the left shell 11 includes a cover plate 111 and a main shell 112. The cover plate 111 and the main shell 112 are detachably connected at the end opposite to the right shell 12. The cover plate 111 is detachably connected to the main shell 112 by screws.

[0043] When the cover plate 111 is opened, the opening of the upper cavity 31 is exposed, which facilitates the installation of the motor 5 and allows the output component 7 and the rotating component 6 to be installed on the cover plate 111.

[0044] Reference Figure 2 , Figure 7 , Figure 8 and Figure 9 As shown, the day and night curtain motor 5 also includes a motor 5 located in the upper cavity 31 and a rotating component 6 rotatably connected in the lower cavity 32. The output end of the motor 5 is drivenly connected to an output component 7. A slot is formed at the output end of the motor 5, and part of the output component 7 is inserted into the slot, thereby forming a connection between the output component 7 and the output end of the motor 5. The inner wall of the slot includes at least one plane to realize the transmission between the output end of the motor 5 and the output component 7.

[0045] The output component 7 meshes with the rotating component 6 for transmission. The rotating component 6 has a first square hole 61, which is used to fit the four corner rods, thereby realizing the power transmission between the rotating component 6 and the four corner rods.

[0046] The output component 7 has a first gear ring 71, and the rotating component 6 has a second gear ring 62. The first gear ring 71 and the second gear ring 62 mesh with each other, and the transmission is carried out by the meshing of the gear rings, which makes the transmission between the output component 7 and the rotating component 6 more stable.

[0047] A connector 8 is rotatably connected at the second through hole. The connector 8 has a second square hole 81, which corresponds to the first square hole 61. Both are used to fit the four corner rods to realize the transmission of power.

[0048] Multiple first rings are integrally formed on the inner side of the cover plate 111, and two second rings are formed on the inner side of the cover body. The second rings correspond to the second through holes, and the two first rings correspond to the first through holes. A first bearing is connected between the rotating parts 6 of the first rings, and a second bearing is connected between the second rings and the connecting parts 8. The arrangement of the first and second rings provides installation space for the first and second bearings, and can increase the rotational stability of the rotating parts 6 and the connecting parts 8. In addition, it allows the rotating parts 6 and the connecting parts 8 to be pre-installed on the cover plate 111 and the cover body, which is convenient for installation.

[0049] Among them, the other two first ring bodies correspond to two output components 7. A third bearing is also connected between the first ring body and the two output components 7 to increase the rotational stability of the output components 7 and facilitate the installation of the output components 7.

[0050] There are two sets of transmission cavity group 3.

[0051] 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.
