Description

Technical Field

[0001] This utility model relates to the field of electric curtain technology, and more specifically to a secondary transmission box for opening and closing curtains. Background Technology

[0002] Electric curtains are very popular. They are made by connecting a motor to a main drive box. The motor drives the curtain to move through the transmission mechanism in the main drive box, thus realizing the opening and closing function of the curtain. In order to enhance the user experience, light strips are added to the curtain track. The light strips are generally oriented towards the room so that users can use them in different situations.

[0003] To extend the range of installable light strip lengths, a connecting groove is created on the auxiliary drive box. This groove connects to the light slot on the track, allowing the light strip to extend into the groove during installation, thus extending the range of installable light strip lengths. However, different users have different needs, and some users do not extend the light strip, resulting in the connecting groove being exposed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a curtain opening and closing auxiliary transmission box, which avoids the connection groove from being exposed without extending the installation length of the light strip.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a curtain opening and closing auxiliary transmission box, including a housing, a connecting groove is provided on one side of the housing, the connecting groove is connected to a corresponding light groove on the track, and a cover plate is detachably connected to the housing at least at the location corresponding to the connecting groove.

[0006] As a further improvement of this utility model, the housing has an upper cavity and a lower cavity, the connecting groove communicates with the upper cavity, and a transmission gear is rotatably connected in the lower cavity.

[0007] As a further improvement of this utility model, the housing includes an outer shell and an inner shell, the outer shell and the inner shell are detachably connected, and at least a portion of the inner shell extends into the outer shell to form the upper cavity and the lower cavity.

[0008] As a further improvement of this utility model, a threaded hole is provided on the side of the inner shell facing the track, and a fixing hole corresponding to the threaded hole is provided on the outer shell.

[0009] As a further improvement of this utility model, the outer shell includes a positioning section, and the inner shell and the track respectively abut against the two ends of the positioning section.

[0010] As a further improvement of this utility model, a slot is provided on the side of the outer shell away from the track, and the inner shell extends into the outer shell through the slot.

[0011] As a further improvement of this utility model, limiting grooves are provided at both the bottom and top of the connecting groove.

[0012] As a further improvement of this utility model, multiple notches are provided between the cover plate and the housing to form a point-discontinuous connection between the cover plate and the housing.

[0013] As a further improvement of this utility model, two connecting grooves are provided, located on opposite sides of the housing respectively.

[0014] As a further improvement of this utility model, a tail hook is detachably connected to the housing.

[0015] The beneficial effects of this utility model are as follows: A cover plate is provided at the connecting groove in this utility model. When the connecting groove is not used, the cover plate is integrally connected with the shell, avoiding the exposure of the connecting groove. If the connecting groove is required, the corresponding cover plate can be removed, so that the user can choose whether to use the connecting groove. The setting of the upper cavity and the lower cavity makes the light strip located on the side of the upper cavity, so that the light strip and the transmission gear do not interfere with each other.

[0021] 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.

[0022] Reference Figures 1 to 4As shown, an opening and closing curtain auxiliary transmission box in this embodiment includes a housing 1. A connecting groove 11 is provided on one side of the housing 1. The connecting groove 11 communicates with the corresponding light groove on the track. A cover plate 2 is detachably connected to the housing 1 at least at the corresponding connecting groove 11 to cover the corresponding connecting groove 11. In one embodiment, the cover plate 2 is connected to the housing 1 by a plug-in connection. An opening is provided on the side of the housing 1 facing the track. A slot is provided at the top and / or bottom of the housing 1. The cover plate 2 is plugged into the housing 1 through the slot.

[0023] In another embodiment, the cover plate 2 is fastened to the housing 1 by a snap-fit ​​connection.

[0024] Preferably, the cover plate 2 and the housing 1 are connected by a point-discontinuity connection.

[0025] Multiple notches 21 are provided between the cover plate 2 and the shell 1 to form a point-discontinuous connection between the cover plate 2 and the shell 1. Under no external force, the cover plate 2 is always connected to the shell 1. In the process of producing the shell 1, only the notches 21 need to be opened, which is convenient for processing and does not require other structural design.

[0026] If you need to use the connecting slot 11, simply pry open the corresponding cover plate 2.

[0027] Without using the connecting groove 11, the cover plate 2 is integrally connected to the housing 1, avoiding the exposure of the connecting groove 11; thus, the user can choose whether or not to use the connecting groove 11.

[0028] Reference Figure 2 As shown, the housing 1 has an upper cavity 12 and a lower cavity 13. The connecting groove 11 is connected to the upper cavity 12. The lower cavity 13 is rotatably connected to a transmission gear 3. The transmission gear 3 is used to connect with a belt to play a transmission role. The other end of the belt is connected to the transmission mechanism in the main transmission box, thereby realizing the opening and closing of the curtain.
