[0061] Example 1

[0062] A specific embodiment of the present invention discloses a temperature-sensitive and light-sensitive sunshade curtain, which uses memory metal as a sunshade telescopic frame. It does not rely on an automatic control system and electric energy, and realizes automatic shading through an automatic temperature-sensitive and light-sensitive sunshade module unit 100. It mainly utilizes the characteristic that memory metal can change its shape and structure as the temperature changes, to achieve adaptive sunshade and lighting.

[0063] like Figures 1 to 5 As shown, the sunshade module unit 100 includes a memory metal skeleton 2 and a metal frame 1, the memory metal skeleton 2 includes two memory metal rods 21, the metal frame 1 has a top cross bar 11, a bottom cross bar 12 and vertical rods 13 on both sides, the vertical rods 13 are provided with guide rails 14, and the guide rails 14 are provided with guide rail grooves; the top end of the memory metal skeleton 2 is fixed to the top cross bar 11 of the metal frame 1, and the two memory metal rods 21 are parallel to each other in a fully straightened state, and the parallel distance between the two memory metal rods 21 is less than the width of the top cross bar 11; the two vertical side rods of the metal frame 1 are provided with guide rails 14, and the guide rail grooves are provided on the guide rails 14, when the memory metal rod 21 is bent and deformed, the bent part can be stuck in the guide rail groove, and the extension and contraction route of the memory metal rod 21 is controlled by the guide rail groove; the memory metal skeleton 2 is wrapped with a surface layer material, the surface layer material is connected to the memory metal skeleton 2, and can be deformed along with the extension and contraction of the memory metal skeleton 2.

[0064] The surface material is a sunshade cloth 3. The sunshade cloth 3 is completely dense and opaque; or, the sunshade cloth 3 is alternately provided with perforated light-transmitting areas 31 and dense areas 32; or, a sunshade cloth 3 with different visible light projection ratios can be selected as needed, and its pattern and texture color can be adjusted and selected according to specific artistry, which is more suitable for the preferences of different groups of people such as the elderly.

[0065] Furthermore, the sunshade cloth 3 has an elastic traction plastic rope 4 built therein, and the elastic traction plastic rope 4 is connected to the bending change of the two memory metal rods 21, which is conducive to the stability of the deformation of the sunshade cloth 3 when it expands and contracts with the memory metal frame 2. The number of the elastic traction plastic ropes 4 is the same as the number of the bending change of the memory metal rod 21, and multiple elastic traction plastic ropes 4 are arranged in parallel between the two memory metal rods 21.

[0066] Furthermore, a metal edge banding strip 33 is provided at the bottom of the sunshade cloth 3. The metal edge banding strip 33 is arranged horizontally. The lateral length of the metal edge banding strip 33 is equal to the width of the sunshade cloth 3. An upper magnetic component 34 is provided at the middle position of the metal edge banding strip 33. A lower magnetic component 15 is provided at the corresponding middle position of the bottom cross bar 12 of the metal frame 1. The upper magnetic component 34 and the lower magnetic component 15 are at different levels. As the temperature rises, the memory metal skeleton 2 stretches and drives the sunshade cloth 3 to unfold and fall. When it is close to the lower magnetic component 15, it is adsorbed as a whole. At this time, the sunshade cloth 3 is flattened and fixed, thereby achieving a comprehensive external shading effect.

[0067] Furthermore, a telescopic rod 35 is set on the top of the sunshade cloth 3, and the tops of the vertical rods 13 on both sides of the metal frame 1 are provided with mounting holes. The two ends of the telescopic rod 35 can be inserted into the mounting holes on both sides, and the sunshade cloth 3 can be disassembled and replaced by contracting and extending the telescopic rod 35.

[0068] Furthermore, both ends of the telescopic rod 35 are provided with snap fasteners, which 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 .

[0069] The sunshade module unit 100 in this example can be applied to windows and similar scenarios, including the following situations:

[0070] The first case, such as Figure 6 to Figure 7 As shown, the sunshade module unit 100 is applied to the existing window 200 and fixed to the existing window 200 as a whole. Specifically, the sunshade module unit 100 is directly fixed to the existing window 200, and as the window is opened or closed. Exemplarily, the sunshade module unit 100 can be combined with the existing casement window, top and bottom hanging window, and center hanging window, and complete the ventilation and sunshade requirements as the window is opened and closed; the metal frame 1 of the sunshade module unit 100 is directly fixed to the existing window 200.

[0071] The second case, such as Figures 8 to 9 As shown, the sunshade module unit 100 is applied to the existing window 200, and is opened and closed independently of the existing window 200. Specifically, the sunshade module unit 100 is connected to the window frame 300, and the sunshade module unit 100 is independently set from the existing window 200, and each is opened and closed independently. In one optional embodiment, the top of the metal frame 1 is hingedly connected to the window frame 300, or a rotating shaft is set at the middle position of the top and bottom of the metal frame 1, and 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 opened and closed independently relative to the existing window 200, meeting the ventilation and shading requirements of the windowless opening environment or the inner casement window; optionally, in the technical solution of the top hinge of the metal frame 1, a support rod fixing groove is reserved at the bottom of the metal frame 1, and the support rod is used to control the opening state of the metal frame 1.

[0072] In this example, the memory metal rod 21 in the bent state is as follows: Figure 5 As shown, the top and bottom of the memory metal rod 21 in this state have straight rod sections that do not participate in bending, the middle section of the metal rod participates in bending, and the middle section of the metal rod participating in bending includes multiple arc sections at the bending locations and multiple straight rod sections on both sides of the bending locations. The length of the memory metal rod 21 is H, and the H value is determined according to the following formula:

[0073] H=H1+h×(n+1)+πRn+H2,

[0074] In the above formula, H = the length of the memory metal rod; H1 is the length of the top straight rod section that does not participate in the bending; H2 is the length of the bottom straight rod section that does not participate in the bending; h is the length of the straight rod sections on both sides of the bend; πR is the length of the arc rod at the bend; R is the radius of the bend, and the bend can be approximately regarded as a semicircle, R = 2R0, n is the number of times the memory metal is bent; R0 is the cross-sectional radius of the memory metal; the value range of the cross-sectional radius R0 of the memory metal is: 1mm-5mm; however, the H value of a single sunshade module unit 100 should not be too large, otherwise it will affect the temperature-sensitive deformation effect of the memory metal rod 21, preferably, H≤3m.

[0075] Since the H value should not be too large, in order to meet the situation of H>3m or even larger window size, multiple sunshade module units 100 can be connected in series for use, so as to meet the use requirements of larger window size. Fig.10As shown, two sunshade module units 100 are spliced ​​into a module unit of a larger size, and the two sunshade module units 100 can be fixedly connected or movably connected. Preferably, the two sunshade module units 100 are hinged, the top of the first sunshade module unit 101 is hinged on the window frame 300, the bottom of the first sunshade module unit 101 is hinged on the top of the second sunshade module unit 102, and the side end of the metal frame 1 of the second sunshade module unit 102 is hinged with a connecting piece, which is slidably connected to the longitudinal slide groove 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.

[0076] Compared with the prior art, the temperature-sensitive and light-sensitive sunshade provided in this embodiment solves the problem of high energy consumption of electric sunshade products and the non-automatic problem of traditional sunshade products. Compared with traditional sunshade products, it is cheaper and lighter, can be adapted to a variety of exterior finishes, and is suitable for the use needs of different groups such as the elderly. It has the advantages of being green, low-carbon and sustainable. Moreover, it can be applied to bus stations, temporary rest areas, temporary meeting areas, outside windows or combined on window bodies, outdoor exhibition halls and other scenes in the form of modular units to meet the needs of different architectural styles.
