[0002] Currently, common automatic sunshade products on the market are mostly electric sunshades or manual sunshade curtains. Although they meet the sunshade requirements, they have certain defects. Electric sunshade curtains or sunshade devices consume a large amount of electric energy, with high construction costs and high maintenance costs; while manual sunshade curtains require human intervention and cannot meet the convenient use requirements. There are often situations where the sunshade is forgotten or the sunshade is forgotten to be closed, resulting in a contradiction between the use of sunshade and daylighting. In addition, fixed sunshades cannot be automatically adjusted according to sunlight and time conditions, and they will affect indoor daylighting when large-area sunshading is not required.

[0046] Embodiment 1

[0047] A specific embodiment of the present utility model discloses a temperature- and light-sensitive sunshade curtain. Using a shape memory alloy as the sunshade telescopic skeleton, it does not rely on an automatic control system and electric energy, and realizes automatic sunshading through the automatic temperature- and light-sensitive sunshade module unit 100. It mainly utilizes the characteristic that the shape memory alloy can change its shape structure with temperature changes to achieve the self-adaptation of sunshading and daylighting.

[0048] As Figures 1 to 5As shown in the figure, the sunshade module unit 100 includes a metal frame 1. A shape memory alloy (SMA) skeleton 2 is provided on the metal frame 1. The metal frame 1 has a top cross bar 11, a bottom cross bar 12, and vertical bars 13 on both sides. Guide rails 14 are provided on the vertical bars 13, and guide rail grooves are provided on the guide rails 14. The SMA skeleton 2 can expand and contract with temperature changes. The top end of the SMA skeleton 2 is fixed to the top cross bar 11 of the metal frame 1, and the bottom end of the SMA skeleton 2 is a free end, which can rise and fall accordingly during the deformation of the SMA skeleton 2. Guide rails 14 are provided on the two vertical side bars of the metal frame 1, and guide rail grooves are provided on the guide rails 14. When the SMA skeleton 2 bends and deforms, the bent part can be caught in the guide rail groove to control the expansion and contraction route of the SMA skeleton 2 through the guide rail groove. The SMA skeleton 2 is wrapped with a surface layer material. The surface layer material is connected to the SMA skeleton 2 and can deform accordingly with the expansion and contraction of the SMA skeleton 2.

[0049] In one alternative embodiment, the SMA skeleton 2 includes two SMA rods 21. When the two SMA rods 21 are in a fully straight state, they are parallel to each other, and the parallel distance between the two SMA rods 21 is less than the width of the top cross bar 11. When the SMA rods 21 bend and deform, the bent part can be caught in the guide rail groove.

[0050] Among them, the surface layer material is a sunshade cloth 3. The sunshade cloth 3 is completely dense and light-tight; alternatively, perforated light-transmitting areas 31 and dense areas 32 are alternately arranged on the sunshade cloth 3; alternatively, sunshade cloths 3 with different visible light transmittance ratios can be selected according to needs, and their patterns and texture colors can be adjusted and selected according to specific artistry, which is more suitable for the usage preferences of different groups such as the elderly.

[0051] Furthermore, elastic traction plastic ropes 4 are built into the sunshade cloth 3. The elastic traction plastic ropes 4 are connected to the bending change positions of the two SMA rods 21, which is beneficial to the stability of the deformation of the sunshade cloth 3 when it expands and contracts with the SMA skeleton 2. Among them, the number of elastic traction plastic ropes 4 is the same as the number of bending change positions of the SMA rods 21, and multiple elastic traction plastic ropes 4 are arranged in parallel between the two SMA rods 21.

[0052] Furthermore, a metal edge seal 33 is provided at the bottom of the sunshade cloth 3. The metal edge seal 33 is arranged horizontally, and the horizontal length of the metal edge seal 33 is equal to the width of the sunshade cloth 3. An upper magnetic part 34 is provided at the middle position of the metal edge seal 33, and a lower magnetic part 15 is provided at the corresponding middle position of the bottom cross bar 12 of the metal frame 1. The upper magnetic part 34 and the lower magnetic part 15 are of opposite polarities. As the temperature rises, the SMA skeleton 2 unfolds and drives the sunshade cloth 3 to unfold and fall. When it is about to approach the lower magnetic part 15, the whole is adsorbed, and the sunshade cloth 3 is flattened and fixed at this time, achieving a comprehensive external sunshade effect.

[0053] Further, a telescopic rod 35 is provided at the top of the sunshade cloth 3. Mounting holes are provided at the tops of the two vertical rods 13 on both sides of the metal frame 1. Both ends of the telescopic rod 35 can be snapped into the mounting holes on both sides, and the disassembly and replacement of the sunshade cloth 3 are realized through the contraction and extension of the telescopic rod 35.

[0054] Further, snap members are provided at both ends of the telescopic rod 35. The snap members are fixedly connected to the sunshade cloth 3 and the memory metal rod 21, and can assist in fixing the memory metal rod 21 and the sunshade cloth 3.

[0055] The sunshade module unit 100 in this embodiment can be applied to windows and similar scenarios, including the following situations:

[0056] The first situation is as Figures 6 to 7 shown. The sunshade module unit 100 is applied to the existing window 200 and is fixed to the existing window 200 as a whole. Specifically, the sunshade module unit 100 is directly fixed on the existing window 200, and as the window is opened or closed. Exemplarily, the sunshade module unit 100 can be compounded on the existing casement window, top-hung window, or center-hung window, and the ventilation and sunshade requirements are completed as the window is opened and closed; the metal frame 1 of the sunshade module unit 100 is directly fixed on the existing window 200.

[0057] The second situation is as Figures 8 to 9 shown. The sunshade module unit 100 is applied to the existing window 200 and is independently opened and closed with the existing window 200. Specifically, the sunshade module unit 100 is connected to the window frame 300. The sunshade module unit 100 is independently arranged from the existing window 200 and is independently opened and closed respectively. In one optional implementation manner, the top of the metal frame 1 is hinged to the window frame 300, or rotating shafts are provided at the middle positions of the top and bottom of the metal frame 1. The axes of the two rotating shafts coincide and are located on the symmetry axis of the metal frame 1, and the metal frame 1 can rotate around the rotating shaft. In this way, the sunshade module unit 100 can be independently opened and closed relative to the existing window 200, meeting the ventilation and sunshade requirements of the windowless opening environment or the inward-opening casement window; optionally, in the technical solution where the top of the metal frame 1 is hinged, a support rod fixing groove is reserved at the bottom of the metal frame 1, and the support rod is used to control the open state of the metal frame 1.

[0058] In this embodiment, the memory metal bone rod 21 in the bent state is as Figure 5 shown. In this state, the top and bottom of the memory metal bone rod 21 have straight rod segments that do not participate in the bending, and the middle metal rod participates in the bending. The middle metal rod participating in the bending includes arc segments at multiple bending points and straight rod segments on both sides of multiple bending points. The length of the memory metal bone rod 21 is H, and the value of H is determined according to the following formula:

[0059] H = H1 + h×(n + 1) + πRn + H2,

[0060] In the above formula, H = the length of the shape memory alloy rod; H1 is the length of the top straight rod section that does not participate in bending; H2 is the length of the bottom straight rod section that does not participate in bending; h is the length of the straight rod sections on both sides of the bending part; πR is the length of the arc-shaped rod at the bending part; R is the radius of the bending part. The bending part can be approximately regarded as a semi-circle, R = 2R0, n is the number of times the shape memory alloy bends; R0 is the cross-sectional radius of the shape memory alloy; the value range of the cross-sectional radius R0 of the shape memory alloy is: 1 mm - 5 mm; however, the value of H of a single sunshade module unit 100 should not be too large, otherwise it will affect the temperature-sensitive deformation effect of the shape memory alloy rod 21. Preferably, H ≤ 3 m.

[0061] Since the value of H should not be too large, therefore, in order to meet the situation of H > 3 m or even larger-sized windows, multiple sunshade module units 100 can be connected in series for use, so as to meet the usage requirements of larger-sized windows. Exemplarily, as Figure 10 shown, two sunshade module units 100 are spliced into a larger-sized module unit. The two sunshade module units 100 can be fixedly connected or movably connected. Preferably, the two sunshade module units 100 are hinged. The top end of the first sunshade module unit 101 is hinged to the window frame 300, the bottom end of the first sunshade module unit 101 is hinged to the top end of the second sunshade module unit 102, and a connecting piece is hinged to the side end of the metal frame 1 of the second sunshade module unit 102. The connecting piece is slidably connected to the longitudinal chute of the window frame 300, so that the first sunshade module unit 101 and the second sunshade module unit 102 are opened in a folding manner.

[0062] Compared with the prior art, the temperature-sensitive and light-sensitive sunshade curtain provided in this embodiment solves the problems of high energy consumption of electric sunshade products and the non-automaticity of traditional sunshade products. Compared with traditional sunshade products, it has a lower cost, is lighter in weight, can adapt to various exterior finish effects, meets the usage requirements of different groups such as the elderly, and has the advantages of being green, low-carbon and sustainable. Moreover, in the form of module units, it can be applied to various scenarios such as bus stops, temporary rest areas, temporary meeting areas, the outside of windows or combined onto window bodies, and outdoor exhibition sites, meeting the requirements of different architectural styles.

As Figures 11 to 12 shown, the structure includes a metal keel frame 400, and the metal keel frame 400 has at least one installation opening 500. The temperature-sensitive and light-sensitive sunshade curtain in Embodiment 1 is installed on the installation opening 500 of the metal keel frame 400 to form a temporary enclosed space. That is, the structure in this embodiment is assembled by the metal keel frame 400 and multiple sunshade module units 100.

[0065] Specifically, a plurality of sunshade module units 100 are installed on a metal keel frame 400 to form a temporary enclosed space, which is a cuboid structure for temporary functional activities such as meetings, social gatherings, and family leisure.

[0066] In one alternative embodiment, the metal keel frame 400 includes a plurality of frame units 600, and the plurality of frame units 600 are spliced into a cuboid frame structure, and one sunshade module unit 100 is installed on one frame unit 600. Specifically, each frame unit 600 is a rectangular frame formed by splicing a plurality of keels 5. As Figure 14 shown, the keel 5 is a rectangular rod-shaped structure, and a groove 51 is provided on the surface of the keel 5. The groove 51 extends along the length direction of the keel 5, that is, the length of the groove 51 is equal to the length of the keel 5. The metal frame 1 of the sunshade module unit 100 can be detachably snapped into the groove 51 to achieve the fixed installation of the sunshade module unit 100. When disassembling, the metal frame 1 can be directly taken out from the groove 51 to complete the disassembly of the sunshade module unit 100.

[0067] At the splicing position of the frame unit 600, the keels 5 are connected by a connecting component 6. Figure 12 The shown structure includes three types of connecting components 6. Among them, Figure 15 the shown connecting component 6 is applicable to the intermediate splicing position, and this type of connecting component 6 connects four keels 5 in four directions; Figure 16 the shown connecting component 6 is applicable to the corner splicing position, and this type of connecting component 6 connects three keels 5 in three directions; Figure 17 the shown connecting component 6 is applicable to the intermediate splicing position, and this type of connecting component 6 connects three keels 5 in three directions.

[0068] Specifically, continuing to refer to Figures 15 to 17 , the connecting component 6 includes a connecting body 61, and the connecting body 61 is connected to the adjacent keels 5 by a mortise and tenon connection method. Exemplarily, as Figure 14 shown, tenon grooves 52 are provided on both end connection faces of the keel 5, and tenon heads 62 adapted to the tenon grooves 52 are provided on the connecting body 61. The number of tenon heads 62 is set according to the number of keels 5 to be connected at the splicing position.

[0069] Furthermore, telescopic metal fasteners 63 are provided on the side end faces of the tenon 62. Correspondingly, fastener grooves are provided on the groove wall faces of the mortise 52. Preferably, the two telescopic metal fasteners 63 are symmetrically arranged on the two side end faces of the tenon 62, and two fastener grooves are provided on the two opposite groove wall faces of the mortise 52. When the tenon 62 is inserted into the mortise 52, the telescopic metal fasteners 63 can be snapped into the fastener grooves; when disassembly is required, the telescopic metal fasteners 63 are forced out of the fastener grooves by an external force, and the tenon 62 is removed from the mortise 52.

[0070] Furthermore, in order to improve the connection stability at the splicing location, the connection assembly 6 further includes an additional anchor 64, and the additional anchor 64 is configured to fix the connection body 61 at the splicing location and all the keels 5. Optionally, the structure of the additional anchor 64 is an L-shaped structure, a T-shaped structure, or other shaped structures. An anchor installation groove 65 is provided on the surface of the connection body 61, and the anchor installation groove 65 can communicate with the groove 51 on the surface of the keel 5 at the splicing location.

[0071] Compared with the prior art, the structure provided in this embodiment forms a temporary enclosed space by assembling the temperature- and light-sensitive sunshade on the metal keel framework for temporary functional activities such as meetings, social gatherings, and family leisure; moreover, the structure of the structure is simple, with a detachable design, simple and convenient assembly, wide application scenarios, and low cost.
