Description

Technical Field

[0001] This utility model relates to the field of window design technology, and in particular to an external shading system for irregularly shaped windows and a dormer window. Background Technology

[0002] The existing houses have dormer windows installed on their roofs, and each pane of glass in the dormer windows is equipped with a sunshade. However, the glass panes of dormer windows are not necessarily regular squares; for example, the glass may be trapezoidal or triangular. For sunshades installed on these irregularly shaped glass panes, it is difficult to completely cover the glass because the two sides of the glass are not at the same height. For example, the sunshade on one side may have reached the end while the sunshade on the other side has not even reached halfway. The poor matching between the sunshade and the glass makes it difficult to install the sunshade. Summary of the Invention

[0003] To address the technical problem of poor matching between sunshade curtains and glass in existing technologies for irregularly shaped windows, this application proposes an external sunshade system and a dormer window suitable for irregularly shaped windows, thus solving the aforementioned technical problem.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] This utility model provides an external sunshade system for irregularly shaped windows, comprising: a mounting frame installed at the higher end of the irregularly shaped window, the mounting frame having an installation space inside its body, and a roller blind wound around the outer circumference of the mounting frame; the roller blind having a counterweight rod at its lower end; and a differential installed within the installation space, the differential comprising two output shafts with different rotational speeds, the output ends of the two output shafts extending from their respective ends of the mounting frame and connected to the respective ends of the counterweight rods via ropes, thereby controlling the lowering speeds of the two ends of the counterweight rods respectively.

[0006] Furthermore, the differential also includes: a drive motor, on the output shaft of which a drive gear is disposed; a driven gear, disposed on the shaft of one of the output shafts and meshing with the drive gear; two sun gears, which are symmetrically arranged and fixed on the input end of their respective output shafts; and two planetary gears, which are symmetrically arranged and mesh with the two sun gears simultaneously.

[0007] Furthermore, the drive motor is disposed outside one end of the mounting bracket, and the output spindle of the drive motor extends from the end of the mounting bracket into the mounting space, so that the driving gear meshes with the driven gear.

[0008] Furthermore, a winding portion is formed on the output end of the output shaft, and the rope is wound on the winding portion. One end of the rope is connected to the output shaft, and the other end is connected to the end of the counterweight rod.

[0009] Furthermore, it also includes a guide assembly, which includes a guide cable and a guide ring sleeved on the guide cable. The guide cable is disposed on both sides of the roller shutter, and the extension direction of the guide cable is the same as the lifting direction of the roller shutter. The guide ring is fixed to the end of the counterweight rod.

[0010] Furthermore, one end of the guide cable is connected to the end of the frame or mounting bracket of the irregular window via a connector. The connector includes a connecting ring that is spaced out and sleeved on the output shaft. The connecting ring is connected to one end of the guide cable, and a connecting pin is formed on the connecting ring. The connecting pin is connected to the end of the frame or mounting bracket of the irregular window, and the other end of the guide cable is connected to the end of the irregular window that is in a lower position.

[0011] Another aspect of this utility model provides a building dormer window, configured on a roof slope, including a facade and a top surface, wherein each facade and the top surface are configured with at least one set of irregularly shaped windows, and the exterior window surface of each set of irregularly shaped windows is configured with the aforementioned building exterior shading system suitable for irregularly shaped windows.

[0012] Furthermore, a waterproof sill is provided at the connection between the building dormer window and the roof slope. The waterproof sill protrudes from the roof slope, and the top end face of the waterproof sill is used to install the building dormer window.

[0013] Furthermore, there is one top surface, and the end of the top surface that connects to the roof slope is the lower end. There are three facades, and the tops of the three facades are all connected to the top surface. Two of the facades are symmetrically arranged on two sides of the top surface, and three sets of irregularly shaped windows are arranged on each of the two symmetrical facades.

[0014] Based on the above technical solution, the technical effects that this utility model can achieve are as follows:

[0015] This utility model discloses an external sunshade system for irregularly shaped windows. The mounting frame is equipped with a differential gear, which controls the descent speed of the roller blind outside the mounting frame. Specifically, the differential gear includes two output shafts with different rotational speeds. The two output shafts are connected to one end of the counterweight rod of their respective roller blinds via ropes, thereby controlling the descent speed of both ends of the counterweight rod, i.e., controlling the descent speed of both sides of the roller blind. This results in the roller blind section on the side with higher glass in the irregularly shaped window descending faster, and the roller blind section on the side with lower glass descending slower, ultimately ensuring that the bottom ends of both sides of the roller blind reach the bottom end of the irregularly shaped window glass simultaneously, thus enabling the roller blind to match the irregularly shaped window glass.

[0016] This utility model discloses an external sunshade system for irregularly shaped windows. The two output shafts of the differential on the mounting bracket are driven by the same drive motor. The first output shaft is directly driven by the drive motor's driving gear through the driven gear on the output shaft. The second output shaft is indirectly driven by the drive motor through the first output shaft. A sun gear is configured at the end of the first output shaft. The sun gear then drives another sun gear on the second output shaft through two planetary gears. By using different gear ratios of the sun gear and planetary gears, one drive motor can simultaneously drive two output shafts with different speeds. Compared with the method of using two motors, the layout is more compact, reducing installation space, production costs, and energy consumption costs during use.

[0017] The building dormer window of this utility model has windows installed on each side of the protruding part of the roof slope, ensuring sufficient lighting and ventilation area. Moreover, there is more than one set of windows, thereby reducing the problem of glass breakage caused by thermal expansion and contraction due to the large glass surface of a single set of windows.
