Description
Technical Field
[0001] The utility model belongs to the technical field of building energy conservation, in particular to an adjustable building exterior sunshade system. Background Art
[0002] Building shading is a necessary measure to prevent direct sunlight from reaching indoor spaces, preventing excessive heating of the building's exterior envelope, thereby preventing localized overheating and glare, and protecting various indoor objects. Its proper design is crucial for improving indoor thermal comfort and reducing building energy consumption in summer.
[0003] Good building shading design has many good effects, mainly the following:
[0004] (1) Effectively preventing solar radiation from entering the room not only improves the indoor thermal environment, but also greatly reduces the building's air conditioning and cooling load in summer.
[0005] (2) It can prevent the building envelope from being overheated and increasing the indoor heat load through secondary radiation and convection, and can also reduce the daily temperature fluctuation of the window structure, thereby preventing the window structure from thermal cracking and extending its service life.
[0006] (3) Building sunshades can effectively prevent glare and improve the indoor light environment. Reasonable sunshade measures can block direct sunlight from entering or convert it into softer diffuse light, thus meeting people's requirements for lighting quality.
[0007] (4) It can prevent direct sunlight, especially ultraviolet rays, from damaging indoor items.
[0008] Based on the above advantages, architectural shading technology has become an indispensable part of contemporary architectural environment design.
[0009] There are many forms and types of building sunshades. Generally speaking, sunshade facilities can be divided into two categories: permanent and temporary. Temporary sunshades refer to sunshades installed on windows.
[0010] Existing building exterior shading systems are mainly used to adjust indoor lighting and reduce indoor temperature, but they usually require manual operation and have a low level of intelligence. They also do not have the function of energy generation. If they are to be transformed into intelligent systems, external energy sources are required. Utility Model Content

Combined with a photosensitive element, it can automatically unfold and retract the sunshade according to light intensity. It is more intelligent and can effectively prevent solar radiation from entering the room, preventing window frames and glass from overheating and increasing the indoor heat load through secondary radiation and convection, improving the indoor thermal environment and significantly reducing the air conditioning load in summer. It can also effectively prevent glare, improve the indoor light environment, and prevent damage to indoor items caused by ultraviolet rays.

The electricity generated by the flexible solar panels can be stored in batteries and used to power the winding motor and photosensitive element, achieving self-sufficiency. In conditions of good light, there is a surplus that can be used by other indoor electrical equipment, reducing power consumption and being more environmentally friendly.
[0015] In the above-mentioned adjustable exterior sunshade system for buildings, the winding shaft is hollow, and the battery is fixedly connected inside the winding shaft.
[0016] The battery is fixed in the winding shaft, which rationally utilizes the internal space of the winding shaft and makes the structure of the external sunshade system more compact.
[0017] In the above-mentioned adjustable exterior building shading system, one end of the winding shaft is fixedly connected to a driven gear, and the output shaft of the winding motor is fixedly connected to a driving gear, and the driving gear and the driven gear are meshed or connected through a chain transmission.
[0018] The winding motor in the exterior sunshade system of this building drives the winding shaft through gear meshing or the cooperation of gears and chains, which can minimize the distance between the two ends of the winding shaft and the window side wall, thereby making the distance between the sunshade and the window side wall smaller, thereby achieving better effect.
[0019] In the above-mentioned adjustable exterior building shading system, the winding shaft is arranged in the winding box body, the upper end of the winding box body is fixedly connected to the upper wall of the window in the wall, both ends of the winding shaft are fixedly connected to the rotating shaft, and the two ends of the winding box body are fixedly connected to the positioning block, the rotating shaft passes through the positioning block and the middle part of the rotating shaft is rotatably connected to the positioning block through a bearing, the driven gear is fixedly connected to the outer end of the rotating shaft, and the winding motor is fixedly connected to the outer side wall or the lower side wall of the winding box body.
[0020] The design of the winding box, the positioning block and the rotating shaft can not only be used to fix the winding shaft so that the winding shaft can be fixedly connected to the window, but also can protect the winding shaft and the sunshade and flexible solar panel rolled up on the winding shaft.

[0022] The cooperation between the limiting rod and the inner opening can fix the upper end of the sunshade curtain to the winding shaft, and the structure of the guide part at the outer opening can prevent the sunshade curtain or the flexible solar panel from sliding and being damaged when passing through the outer opening.
[0023] In the above-mentioned adjustable exterior building shading system, it also includes a slide rail, the lower end of the sunshade is fixedly connected to a support rod, and the slide rail has two sections respectively installed on the walls on both sides of the sunshade, and the two ends of the support rod are respectively slidably connected to the slide rail.
[0024] The design of the above-mentioned slide rail can position the support rod at the lower end of the sunshade. Otherwise, if the support rod is suspended in the air, it will easily flutter disorderly under the action of wind, which will not only affect the sunshade effect, but may also cause damage to the flexible solar panel, posing a safety hazard.
[0025] In the above-mentioned adjustable exterior building shading system, a T-shaped slide groove is provided on the slide rail, and both ends of the support rod can extend into the slide groove. Both ends of the support rod are fixedly connected with a counterweight slider, and the counterweight slider can be slidably set in the slide groove.

The base of the electric top rod is fixedly connected to the wall, the driving rod of the electric top rod is rotatably connected to the middle and upper part of the slide rail, and the electric top rod is electrically connected to the battery.

The photosensitive element and the wind speed sensor are both electrically connected to the battery.
[0032] The photosensitive element is set at the lower end of the slide rail, which has higher control accuracy. It avoids the situation in some usage scenarios where sunlight has already entered the lower part of the window while the upper part of the window is still blocked, resulting in the sunshade not opening in time; the design of the wind speed sensor can retract the sunshade and flexible solar panel in time when the wind speed is too high, to prevent the sunshade or flexible solar panel from being damaged by strong winds.

DETAILED DESCRIPTION
[0046] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0047] This adjustable exterior building shading system includes a winding shaft 2, a winding motor 4, a battery 21, a sunshade 5 and a flexible solar panel 6. The output shaft of the winding motor 4 is transmission-connected to one end of the winding shaft 2. One end of the sunshade 5 is fixedly connected to the winding shaft 2, and the other end is equipped with a photosensitive element 91. The flexible solar panel 6 is fixedly connected to the outer surface of the sunshade 5. The flexible solar panel 6 is electrically connected to the battery 21 and can store the generated electrical energy in the battery 21. The battery 21 is electrically connected to the winding motor 4 and the photosensitive element 91, respectively. The battery 21 can provide electrical energy for the winding motor 4 and the photosensitive element 91. The exterior sunshade system of this building can drive the sunshade curtain 5 to unfold or retract via the winding motor 4. In conjunction with the photosensitive element 91, the sunshade curtain 5 can be automatically unfolded and retracted according to the light intensity. It is more intelligent and can effectively prevent solar radiation from entering the room, preventing excessive heating of window frames and glass cups, which would increase the indoor heat load through secondary radiation and convection, thereby improving the indoor thermal environment and significantly reducing the air conditioning refrigeration load in summer. It can also effectively prevent glare, improve the indoor light environment, and prevent damage to indoor items caused by ultraviolet rays. The flexible solar panel 6, due to its soft and rollable nature, can better adapt to the working state where the sunshade curtain 5 needs to be frequently unfolded and retracted, and can be retracted together on the winding shaft 2 when not needed. The electricity generated by the flexible solar panel 6 can be stored in the battery 21 and provides power to the winding motor 4 and the photosensitive element 91, achieving self-sufficiency. In good light conditions, there is a surplus that can be used by other indoor electrical equipment, reducing power consumption and being more environmentally friendly.
[0048] like Figure 4-7 The winding shaft 2 is hollow, and the battery 21 is fixedly connected to the winding shaft 2. The battery 21 is fixed in the winding shaft 2, and the internal space of the winding shaft 2 is reasonably utilized, making the structure of the external sunshade system more compact.
[0049] Furthermore, one end of the winding shaft 2 is fixedly connected to a driven gear 23, and a driving gear 41 is fixedly connected to the output shaft of the winding motor 4, and the driving gear 41 and the driven gear 23 are meshed or connected by a chain transmission; the winding shaft 2 is arranged in the winding box body 3, and the upper end of the winding box body 3 is fixedly connected to the upper wall of the window in the wall 1, and both ends of the winding shaft 2 are fixedly connected to the rotating shaft 22, and both ends of the winding box body 3 are fixedly connected to the positioning block 31, the rotating shaft 22 passes through the positioning block 31 and the middle part of the rotating shaft 22 is rotatably connected to the positioning block 31 through a bearing, The driven gear 23 is fixedly connected to the outer end of the rotating shaft 22, and the winding motor 4 is fixedly connected to the outer wall or the lower wall of the winding box body 3; the upper end of the sunshade 5 is fixedly connected to the limiting rod 51, and an elongated inner opening 24 is axially provided on the winding shaft 2. The limiting rod 51 is located inside the winding shaft 2 and the diameter of the limiting rod 51 is greater than the width of the inner opening 24. An outer opening 32 is provided on the lower side wall of the winding box body 3, and the sunshade 5 passes through the outer opening 32. The outer opening 32 is close to the outer wall of the winding box body 3, and the two sides of the outer opening 32 are curled downward to form a guide portion 33.
[0050] In the exterior sunshade system of this building, the winding motor 4 drives the winding shaft 2 through gear meshing or the cooperation of gears and chains, which can reduce the distance between the two ends of the winding shaft 2 and the side walls of the window as much as possible, thereby making the distance between the sunshade 5 and the side walls of the window smaller, so that the effect is better; the design of the winding box body 3 and the positioning block 31 and the rotating shaft 22 can not only be used to fix the winding shaft 2 so that the winding shaft 2 can be fixedly connected to the window, but also can protect the winding shaft 2 and the sunshade 5 and flexible solar panel 6 wound on the winding shaft 2; the limit rod 51 and the inner opening 24 cooperate to make the upper end of the sunshade 5 fixedly connected to the winding shaft 2, and the structure of the guide part 33 at the outer opening 32 can avoid sliding damage to the sunshade 5 or the flexible solar panel 6 when passing through the outer opening 32.
[0051] like Figure 1-3As shown, the adjustable exterior building sunshade system also includes a slide rail 7. The lower end of the sunshade curtain 5 is fixedly connected to a support rod 52. The slide rail 7 has two sections respectively installed on the wall 1 on both sides of the sunshade curtain 5. The two ends of the support rod 52 are slidably connected to the slide rail 7. A T-shaped slide groove 71 is provided on the slide rail 7. The two ends of the support rod 52 can be extended into the slide groove 71. Both ends of the support rod 52 are fixedly connected to a counterweight slider 521. The counterweight slider 521 can be slidably set in the slide groove 71. The counterweight slider is in the shape of a roller. The design of the above-mentioned slide rail 7 can play a positioning role for the support rod 52 at the lower end of the sunshade curtain 5. Otherwise, if the support rod 52 is suspended in the air, it is easy to flutter disorderly under the action of wind, which not only affects the sunshade effect, but also may cause damage to the flexible solar panel 6, posing a safety hazard; the T-shaped slide groove 71 can not only limit and guide the support rod 52 in the length direction of the slide rail 7, but also limit the support rod 52 in the length direction of the support rod 52, so that the sunshade curtain 5 is more stable after unfolding. The design of the counterweight slider can pull down the sunshade curtain 5, so that the sunshade curtain 5 has a better unfolding effect when unfolded, and can effectively avoid the occurrence of local curling; the roller-shaped counterweight slider can roll more smoothly along the length direction of the slide groove 71, with less friction, so that the process of unfolding or retracting the sunshade curtain 5 is smoother.
[0052] Furthermore, the adjustable exterior sunshade system for buildings also includes two electric top rods 8, which are fixedly connected to the wall 1 on the side of the slide rail 7 away from the sunshade curtain 5. The two electric top rods 8 are symmetrically arranged on the left and right sides, and the bases of the electric top rods 8 are fixedly connected to the wall 1. The driving rods of the electric top rods 8 are rotatably connected to the middle and upper part of the slide rail 7. The electric top rods 8 are electrically connected to the battery 21. The design of the electric top rods 8 can push the lower end of the sunshade curtain 5 outward, so that the flexible solar panel 6 is as perpendicular to the sunlight as possible, thereby achieving better power generation efficiency; after pushing the lower end of the sunshade curtain 5 outward, while ensuring the sunshade effect, it can also provide better ventilation in the room.
[0053] A photosensitive element 91 is provided at the lower end of the slide rail 7, and a wind speed sensor 92 is provided at the lower end of the slide rail 7 or on the outer side wall of the wall 1. Both the photosensitive element 91 and the wind speed sensor 92 are electrically connected to the battery 21. The photosensitive element 91 provided at the lower end of the slide rail 7 has higher control accuracy, avoiding the situation in which the sunshade 5 is not opened in time due to sunlight entering the lower part of the window while the upper part of the window is still blocked in some usage scenarios; the design of the wind speed sensor 92 can promptly retract the sunshade 5 and the flexible solar panel 6 when the wind speed is too high, preventing the sunshade 5 or the flexible solar panel 6 from being damaged by strong winds.
[0054] Furthermore, the present exterior sunshade system also includes a controller, which is electrically connected to the battery 21, the winding motor 4, the electric push rod 8, the photosensitive element 91, and the wind speed sensor 92. The controller is capable of receiving and processing electrical signals from the photosensitive element 91 and the wind speed sensor 92, and then driving the winding motor 4 and / or the electric push rod 8 in response to the received electrical signals. Specifically, the controller can be a single-chip microcomputer or a programmable logic controller. In this embodiment, an STM32F4 single-chip microcomputer is used as the controller.
