If it is described as first, second, it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the sequence of indicated technical features.

[0035] In the description of the present application, unless otherwise explicitly limited, the words such as setting, mounting, connecting and the like should be broadly understood, and the person skilled in the art can reasonably determine the specific meaning of the above words in the present application according to the specific content of the technical scheme.

[0036] In the description of the present invention, reference to terms such as "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the exemplary expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0037] In the related art, electric curtains need to be installed on the wall and set opposite to the windows. However, due to differences in house designs, the installation environment in different houses is different. For example, in some cases, there are sockets near the windows. At this time, the installation of electric curtains needs to avoid the sockets. However, due to the large size of the motor, it is easy to interfere with the socket, resulting in excessive difficulty in installation. In existing electric curtains, the relative position of the motor on the electric curtain is fixed. Therefore, if it is necessary to avoid devices such as sockets, the overall position of the electric curtain needs to be changed, affecting the user experience. In addition, light strips are usually powered by external cables. The setting of external cables will also take up a certain amount of space, and concessions need to be made in the structure for crossing the wires. This will make the structural design complicated and the cost high.

[0038] See also Figures 1 to 4 , Figure 1 1 is a schematic diagram of the three-dimensional structure of the curtain retracting and extending device 100 when the motor assembly 30 is in the second installation state according to an embodiment of the present invention; Figure 2 1 is a schematic diagram of the three-dimensional structure of the curtain retracting and extending device 100 when the motor assembly 30 is in a first installation state according to an embodiment of the present invention; Figure 3 yes Figure 1 A schematic structural diagram of the curtain retracting and extending device 100 in a disassembled state; Figure 4 yes Figure 1 Schematic diagram of the cross-sectional structure of the curtain retracting and extending device 100. An embodiment of the present utility model provides a curtain retracting and extending device 100, which includes a curtain rod 10, a connecting seat 20 and a motor assembly 30. The curtain rod 10 is used to install a light strip (not shown) and a curtain (not shown). The connecting seat 20 is used to install the curtain rod 10 and is provided with a conductive member 21 for electrically connecting to the light strip. The motor assembly 30 is provided with an electrical connector 311 and is installed on the connecting seat 20. The motor assembly 30 has a first installation state and a second installation state. When the motor assembly 30 is in the first installation state, the motor assembly 30 is located on the top side of the connecting seat 20, and the electrical connector 311 is connected to the conductive member 21. When the motor assembly 30 is in the second installation state, the motor assembly 30 is located on the bottom side of the connecting seat 20, and the electrical connector 311 is connected to the conductive member 21.

[0039] Specifically, the driving motor 31 can drive the curtain to move along the curtain rod 10, so that the curtain is retracted or released. In this embodiment, the curtain rod 10 extends in the horizontal direction, that is, the curtain can move along the curtain rod 10 in the horizontal direction.

[0040] In this embodiment, the curtain retraction and release device 100 further comprises a pulley fastener 40, which is arranged at the bottom side of the curtain rod 10 and clamped between the curtain rod 10 and the connecting seat 20. The pulley fastener 40 is used to connect the pulley of the curtain to achieve the installation of one end of the curtain. The pulley fastener 40 is in a clamping relationship with the connecting seat 20, and the user can complete the plug-in installation by plugging in or pulling out the pulley fastener 40 through external force. In this way, the installation of the curtain is facilitated.

[0041] It can be understood that when there is an interference device (such as a socket) on the wall where the curtain retraction and release device 100 is installed, if the interference device is located at the bottom side of the connecting seat 20, the motor assembly 30 can be installed in the first installation state, and at this time the motor assembly 30 is located at the top side of the connecting seat 20, so as to avoid the interference device.
