Description

Technical Field

[0001] The invention relates to the technical field of window design, in particular to an exterior sunshade system for buildings and a dormer window for buildings suitable for special-shaped windows. Background Art

[0002] Dormer windows are installed on the roofs of existing houses. Each glass of the dormer windows is equipped with a sunshade. However, the glass of the dormer windows is not necessarily a regular square. For example, the glass may be trapezoidal or triangular. For the sunshade matched with such special-shaped glass, it is difficult for the sunshade to completely cover the glass because the two sides of the glass are at different heights. For example, the sunshade on one side may have reached the bottom while the sunshade on the other side has not reached halfway. The poor matching between the sunshade and the glass makes it difficult to arrange the sunshade. Summary of the Invention

[0003] In order to solve the technical problem of poor matching between sunshades and glass of special-shaped windows in the prior art, the present application proposes an exterior sunshade system and a building dormer window suitable for special-shaped windows, which solves the above technical problem.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] The present invention provides an exterior sunshade system for buildings suitable for special-shaped windows, comprising: a mounting frame, the mounting frame being mounted at one end of the special-shaped window that is located at a high ground level, a mounting space being formed inside a frame body of the mounting frame, a roller blind being wound on an outer peripheral surface of the frame body of the mounting frame; a roller blind, a counterweight rod being provided at a falling end of the roller blind; and a differential, the differential being mounted in the mounting space, the differential comprising two output shafts with different rotational speeds, the output ends of the two output shafts extending from respective corresponding ends of the mounting frame and connected to respective end portions of the counterweight rods via ropes, thereby respectively controlling the falling speeds of the two ends of the counterweight rods.

[0006] Furthermore, the differential also includes: a drive motor, a driving gear is configured on the output main shaft of the drive motor; a driven gear, the driven gear is configured on the shaft body of one of the output shafts and meshes with the driving gear; two sun gears, the two sun gears are symmetrically arranged and fixed on the input ends of their respective corresponding output shafts; two planetary gears, the two planetary gears are symmetrically arranged and mesh with the two sun gears at the same time.

[0007] Furthermore, the driving motor is arranged outside one end portion of the mounting frame, and the output main shaft of the driving motor extends from the end portion of the mounting frame into the mounting space, so that the driving gear is engaged with the driven gear.

[0008] Furthermore, a winding portion is formed on the output end of the output shaft, 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 rope and a guide ring mounted on the guide rope. The guide rope is arranged on both sides of the roller blind. The extension direction of the guide rope is the same as the lifting direction of the roller blind. The guide ring is fixed to the end of the counterweight rod.

[0010] Furthermore, one end of the guide rope is connected to the end of the frame or mounting frame of the special-shaped window through a connecting piece, and the connecting piece includes a connecting ring that is sleeved on the output shaft in space, and the connecting ring is connected to one end of the guide rope, and a connecting pin is formed on the connecting ring, and the connecting pin is connected to the end of the frame or mounting frame of the special-shaped window, and the other end of the guide rope is connected to the end of the special-shaped window that is in a low position.

[0011] Another aspect of the present invention provides a building dormer window, which is arranged on the roof slope, including a facade and a top surface. Each of the facade and the top surface is provided with at least one group of special-shaped windows, and the outer window surface of each group of special-shaped windows is provided with the above-mentioned building external sunshade system suitable for special-shaped windows.

[0012] Furthermore, a waterproof step is provided at the connection between the building dormer window and the roof slope, the waterproof step protrudes from the roof slope, and the top end surface of the waterproof step is used for installing the building dormer window.

[0013] Furthermore, there is one top surface, and the end where the top surface is connected to the roof slope is the end with low terrain. There are three facades, and the top ends of the three facades are all connected to the top surface, two of which are symmetrically arranged on the two side surfaces of the top surface, and three groups of special-shaped windows are arranged on the two symmetrical facades.

[0014] Based on the above technical solution, the technical effects that can be achieved by the present invention are:

[0015] The exterior sunshade system for buildings suitable for special-shaped windows of the present invention is equipped with a differential in a mounting frame, and the differential is used to control the falling speed of the roller blind outside the mounting frame. Specifically, the differential includes two output shafts with different rotational speeds, and the two output shafts are connected to one end of the counterweight rod of the corresponding roller blind through ropes, thereby respectively controlling the falling speed of the two ends of the counterweight rod, that is, respectively controlling the falling speed of the two sides of the roller blind, so that the roller blind portion on the side with the higher height of the special-shaped window glass falls faster, and the roller blind portion on the side with the lower height of the special-shaped window glass falls slower, and finally the bottom ends of both sides of the roller blind reach the bottom end of the special-shaped window glass at the same time, so that the roller blind can match the special-shaped window glass;

[0016] The present invention is suitable for an exterior sunshade system for buildings with special-shaped windows. The two output shafts of the differential on the mounting frame are output by the same drive motor, wherein the first output shaft is directly driven by the driving gear of the drive motor through the driven gear on the output shaft, and the second output shaft is indirectly driven by the drive motor via the first output shaft. A sun gear is disposed at the end of the first output shaft, and the sun gear drives another sun gear on the second output shaft via two planetary gears. By coordinating the different gear ratios of the sun gear and the planetary gears, one drive motor can simultaneously drive two output shafts with different rotational speeds. Compared with a method of driving with two motors, the layout is compact, installation space is reduced, and production costs and energy consumption costs during use are reduced.

[0017] The building dormer window of the present invention is equipped with windows on each surface of the part protruding from the roof slope, ensuring sufficient lighting and ventilation areas. In addition, there is more than one group of windows, thereby reducing the problem of glass breakage caused by thermal expansion and contraction due to excessive glass surface in a single group of windows.
