[0002] An electric curtain motor is a device that enables curtains to open and close automatically. Currently, one type of transmission method for electric curtain motors on the market, as shown in patent documents such as CN201263033Y (publication number CN201263033Y) or 202423057746.4, involves two conductive strips and a rack within the curtain track. A movable body is also arranged within the curtain track. This movable body is equipped with brushes, a drive wheel, and a motor that drives the gears. The brushes conduct electricity in contact with the conductive strips, and the drive wheel on the movable body meshes with the rack on the curtain track. When the motor drives the gears to rotate, the gears move the movable body within the curtain track. By passing electricity of different polarities through the two conductive strips, the forward and reverse rotation of the motor can be controlled, and the movement of the movable body enables the curtains to open and close.

Example 1

[0032] refer to Figure 1 and Figure 2 An embodiment of this utility model illustrates a curtain rail, including a rail body 11. The rail body 11 includes a transmission portion 11a and a positioning portion 11b, which are divided vertically. The transmission portion 11a has a first mounting groove 112 and a second mounting groove 113 arranged opposite to each other on both sides. The first mounting groove 112 is used to mount a transmission belt 12, and the second mounting groove 113 is used to mount a conductive strip 13. The positioning portion 11b is located above the transmission portion 11a and includes a positioning plate 115 that is vertically arranged and extends along the length of the rail body 11. The positioning plate 115 is located at the top of the transmission portion 11a, and a horizontal plate 116 is provided on the positioning plate 115 away from the edge of the rail body 11. A support portion 111 is formed at the top of the transmission portion 11a, and the support portion 111 extends along the length of the rail body 11 for hanging a movable body 2.

[0033] Specifically, to facilitate understanding of the superior structure of the aforementioned curtain track, a movable body 2 is provided, such as... Figures 3 to 5 The movable body 2 is slidably disposed along the guide rail body 11; the movable body 2 is provided with a conductive contact 22 and a transmission wheel 21, the transmission wheel 21 is located on one side of the guide rail body 11 and meshes with the transmission belt 12, the conductive contact 22 is in contact with the conductive strip 13 and conducts electricity; the conductive contact 22 is configured to be held against the conductive strip 13 by elastic force; the movable body 2 is provided with a driver 3, the driver 3 is a motor, the driver 3 drives the transmission wheel 21 on the movable body 2 to rotate, thereby realizing the movement of the movable body 2 on the curtain guide rail, the driver 3 forms an electrical connection with the conductive strip 13 through the conductive contact 22; for the cooperation method and materials of the conductive contact 22 and the conductive strip 13, please refer to the patent information with application number 202423057746.4.

[0034] The movable body 2 is provided with a suspension part 24 for hanging on the support part 111, and the suspension part 24 is a roller.

[0035] The movable body 2 is equipped with a self-adjusting mechanism 4, which includes two sets of elastic side-pressure components 41 distributed on both sides of the curtain rail 1. Each elastic side-pressure component 41 includes a first side-pressure roller 411 and a second side-pressure roller 412, which are spaced apart along the length of the curtain rail 1. Both the first and second side-pressure rollers are configured to abut against the side of the curtain rail 1 under elastic force. The forces exerted by the two sets of elastic side-pressure components 41 on the side of the curtain rail 1 are opposite. In this embodiment, the elastic side-pressure components 41 are located on the outside of the curtain rail 1, and the first and second side-pressure rollers 411 and 412 abut against the outer surface of the curtain rail 1.

[0036] Specifically, the elastic side pressure assembly 41 further includes a swing arm 413 and a first elastic element 414; the swing arm 413 has two parts, which correspond to the first side pressure wheel 411 and the second side pressure wheel 412 respectively; the first end of the swing arm 413 is hinged to the moving body 22 around a vertical pivot 415, and the second end of the swing arm 413 is rotatably connected to the first side pressure wheel 411 / second side pressure wheel 412; the first elastic element 414 causes the swing arm 413 to swing around its first end.

[0037] Among them, the guide rail body 11 is a curved rail structure.

[0038] Specifically, when the aforementioned movable body 2 is engaged with the curtain rail of this embodiment, the suspension part 24 of the movable body 2 rolls against the support part 111, and the overall weight of the movable body 2 is borne by the suspension part 24; as Figure 7 As shown, when the moving body 22 moves to the curved section of the guide rail body 1111, the bending change of the guide rail body 1111 will cause the force on the two elastic side pressure components 41 to change. Since the first side pressure wheel 411 and the second side pressure wheel 412 in the elastic side pressure component 41 are tightly pressed against the side of the positioning plate 115115 by the elastic force, the moving direction of the moving body 22 will automatically adapt to the bending direction of the guide rail body 1111, thus realizing the self-adjustment function.

[0039] In this embodiment, the first mounting groove 112 and the second mounting groove 113 are arranged opposite to each other, that is, the opening direction of the groove of the first mounting groove 112 is opposite to that of the groove of the second mounting groove 113; thus, the transmission belt 12 and the conductive strip 13 can be arranged opposite to each other. Of course, there are two conductive strips 13. In this way, the structure of the transmission part 11a in the curtain rail can make the width of the curtain rail thinner and the volume of the curtain rail smaller. At the same time, through the cooperation of the positioning plate 115 on the positioning part 11b and the self-adjusting mechanism 4, the moving body 2 can adjust its travel direction according to the bending change of the rail body 11.

[0040] In the above scheme, such as Figure 2 As shown, the support portion 111 has an upwardly protruding guard edge 1112 at its edge. In this way, the guard edge 1112 can prevent the suspension portion 24 of the movable body 2 from detaching from the support portion 111 of the curtain track.

[0041] Thus, this embodiment divides the guide rail body 11 into a transmission part 11a and a positioning part 11b. The installation positions of the transmission belt 12 and the conductive strip 13 are reasonably set in the transmission part 11a so as to cooperate with the moving body 2 to realize transmission. By designing the positioning part 11b, it can cooperate with the self-adjusting mechanism 4 required to realize the curved rail, thereby realizing the curved rail configuration of the curtain machine, which greatly expands the application scenarios of the electric curtain machine, can meet the curtain installation needs of different building structures and different spatial layouts, and improve the versatility and market competitiveness of the product. Example 2

[0042] like Figure 8 As shown, the difference between Embodiment 2 and Embodiment 1 lies in the different positional distribution relationship between the transmission part 11a and the positioning part 11b. Specifically, in this embodiment, the positioning part 11b is located below the transmission part 11a, and the positioning plate 115 is located at the bottom of the transmission part 11a. The horizontal plate 116 serves as a support part 111, and the support part 111 has an upward-facing support surface 1111.

[0043] Thus, see Figure 6 It can be seen that the curtain rail in Embodiment 1 is suitable for a structure in which the self-adjusting mechanism 4 is on top and the transmission wheel 21 is on the bottom in the moving body 2; while the curtain rail in Embodiment 2 is suitable for a structure in which the self-adjusting mechanism is on the bottom and the transmission wheel 21 is on top in the moving body 2. In fact, the principles of Embodiment 1 and Embodiment 2 are the same.

[0044] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
