The accompanying drawings form a part of the present invention and are used together with the embodiments of the present invention to explain the principle of the present invention, rather than to limit the scope of the present invention.

[0052] Embodiment 1

[0053] A specific embodiment of the present invention, as Figure 1 shown, discloses a building component with adjustable light transmittance (hereinafter referred to as building component), including a light-shielding part 1, a base 2, a pipe 3 and a frame. The base 2 is respectively connected to the light-shielding part 1 and the pipe 3. The pipe 3 is arranged on the frame. The building component includes a plurality of pipes 3, and a plurality of bases 2 are arranged on the pipe 3. One light-shielding part 1 is arranged on each base 2. When sunlight or direct light irradiates the light-shielding part 1, an opaque area can be formed at the backlight side of the light-shielding part 1. The light-shielding part 1 changes its own shape, thereby changing the size of the opaque area, and thus can change the total light transmittance of the building component of the present invention.

[0054] The building component of the present invention is arranged on a building to block sunlight or direct light, and the building component can be used as a door, a window, a wall or a ceiling.

[0055] Preferably, as Figure 2 shown, the light-shielding part 1 includes a plurality of blades 11. The shape of the blades 11 is not limited. One end of the blade 11 is fixedly connected to the base 2, and this end is the fixed end, and the other end is the free end. As Figure 2 shown in the right part, when the temperature of the blade 11 is lower than room temperature, that is, when the temperature is less than 22 °C, the blade 11 is in a curled state, that is, the free end of the blade 11 bends towards the fixed end, and the opaque area falls on the base 2. At this time, the light transmittance of the building component of the present invention is the largest; as Figure 2 shown in the left part, when the temperature of the blade 11 is above room temperature, that is, when the temperature is greater than or equal to 22 °C, the blade 11 is in a stretched state, that is, the free end of the blade 11 is coplanar with the fixed end. Under the condition of the same light irradiation angle, the area of the opaque area is the largest. At this time, the light transmittance of the building component of the present invention is the smallest.

[0056] Meanwhile, as Figure 3 shown, when the light-shielding part 1 is in a stretched state, two adjacent light-shielding parts 1 can be connected to form a continuous opaque area, so that the area of the opaque area is the largest.

The shape recovery temperature of this shape memory alloy is 22°C - 87°C. That is, when the temperature is less than 22°C, the blade 11 is in a curled state, and the light transmittance of the building component of the present invention is the largest; when the temperature is between 22°C and 87°C, it is in a stretched state, that is, the free end and the fixed end of the blade 11 are coplanar, and under the condition of the same light illumination angle, the area of the light-blocking region is the largest, and at this time the light transmittance of the building component of the present invention is the smallest. By changing the ratio of titanium-nickel-copper, different shape memory alloys can also be obtained.

[0058] Preferably, the blade 11 includes a plurality of shape memory alloy sheets, which are fixedly connected. Each shape memory alloy sheet has the same shape, and the metal ratios of the plurality of shape memory alloy sheets are different, having different temperature ranges for restoring shapes. Thus, the degree of curling of the blade 11 at different temperatures is different, resulting in different areas of the light-blocking region, and further, the temperature of the light-blocking portion 1 can be used to control the light transmittance of the light-blocking portion 1. The temperature of the light-blocking portion 1 can be controlled by the pipeline 3.

[0059] Preferably, an absorbent coating is applied on the side of the blade 11 facing the light source. The absorbent coating can prevent light reflection and convert light into heat energy to ensure the heat supply of the blade 11 to the pipeline 3.

[0060] When sunlight or other direct light irradiates the light-blocking portion 1, the light-blocking portion 1 absorbs heat and thus heats up, and the heat can be transferred to the base 2. A coolant flows in the pipeline 3, and the coolant can flow through the base 2 and absorb the heat of the base 2.

[0061] Preferably, the coolant is water. The temperature of the coolant flowing into the pipeline 3 is below 22°C, and the temperature when flowing out of the pipeline 3 is above 22°C. When the water temperature flowing out of the pipeline 3 is between 40°C and 80°C, the coolant can be used as domestic hot water.

[0062] Preferably, the building component of this embodiment further includes a covering member (not shown in the figure), and the covering member is made of a transparent material.

The control system includes a controller, a light sensor, and a temperature sensor. Both the light sensor and the temperature sensor are connected to the controller. There are multiple light sensors for measuring the light transmittance of the building component of this embodiment. The temperature sensors are arranged at both ends of the pipeline 3 for respectively measuring the temperatures of the coolant flowing into and out of the pipeline 3.

[0065] Preferably, the building component of this embodiment further includes a pump (not shown in the figure). The pump is respectively connected to the pipeline 3 and the controller. The pump is used to provide power for the flow of the coolant. The controller can control the rotation speed of the pump according to the light transmittance data transmitted by the light sensor and the temperature data transmitted by the temperature sensor, so as to control the flow rate of the coolant in the pipeline 3, adjust the curling degree of the light-shielding part 1, control the area size of the light-impermeable area, and finally control the light transmittance size of the building component of this embodiment.

[0066] Compared with the prior art, the building component of this embodiment is arranged on a building to block sunlight or direct light. The building component can be used as a door, window, wall, or ceiling; when the temperature is less than 22 °C, the blades 11 of the light-shielding part 1 are in a curled state, and the light transmittance of the building component of the present invention is the largest; when the temperature is between 22 °C and 87 °C, it is in a stretched state, that is, the free end and the fixed end of the blade 11 are coplanar. Under the condition of the same light illumination angle, the area of the light-impermeable area is the largest, and at this time the light transmittance of the building component of the present invention is the smallest; the curling degree of the light-shielding part 1 is different at different temperatures, resulting in different areas of the light-impermeable area. Furthermore, the temperature of the light-shielding part 1 can be used to control the light transmittance size of the light-shielding part 1, and finally control the light transmittance size of the building component of this embodiment.

[0067] Embodiment 2

The posture of the light-shielding sheets 12 can be adjusted between two extreme states perpendicular to the pipeline 3 and parallel and completely attached to the pipeline 3. The light-shielding sheets 12 increase the light-shielding area of the light-shielding part 1.

[0070] Preferably, the blade 11 can be a single-piece shape memory alloy sheet. When the temperature is less than the lowest temperature for restoring the shape, the light-shielding sheet 12 is perpendicular to the pipeline 3, making the light transmittance of the building component of this embodiment the largest; when the temperature rises to greater than or equal to the lowest temperature for restoring the shape, the light-shielding sheet 12 is parallel and closely attached to the pipeline 3, making the light transmittance of the building component of this embodiment the smallest.

[0071] Preferably, the blade 11 can be a plurality of shape memory alloy sheets. The plurality of shape memory alloy sheets are fixedly connected, and each shape memory alloy sheet has the same shape. Different shape memory alloy sheets are made of different materials and have different temperature ranges for restoring shapes.

[0074] Preferably, the light-shielding part 1 further includes a heat transfer sheet 13. The heat transfer sheet 13 is arranged on the side where the light-shielding sheet 12 contacts the pipe 3. The heat transfer sheet 13 is parallel to the pipe 3 and perpendicular to the light-shielding sheet 12. When the light-shielding sheet 12 is connected to the pipe 3, the heat transfer sheet 13 can also be completely connected to the pipe 3 to assist the light-shielding sheet 12 in transferring heat to the pipe 3.

[0075] Preferably, the pipe 3 includes a first pipe 31 and a second pipe 32. The first pipe 31 and the second pipe 32 are both connected to the same base 2. A gap is provided between the first pipe 31 and the second pipe 32. The heat transfer sheet 13 can be inserted into the gap and connected to the first pipe 31 and the second pipe 32 respectively. There are 3 heat transfer sheets 13, and the 3 heat transfer sheets 13 are parallel to each other. The distance between two adjacent heat transfer sheets 13 is the width or diameter of the pipe 3. The two heat transfer sheets 13 on both sides can be respectively connected to the first pipe 31 and the second pipe 32, and the middle heat transfer sheet 13 can be inserted into the gap. The 3 heat transfer sheets 13 all transfer heat to the pipe 3, increasing the efficiency of the light-shielding sheet 12 in transferring heat to the pipe 3.

[0076] Preferably, as Figure 6 shown, the light-shielding part 1 includes two blades 11, and one light-shielding sheet 12 is connected to each blade 11. The light-shielding sheet 12 is provided with a notch, and both sides of the notch are extension parts 14. When the light-shielding sheet 12 is perpendicular to the pipe 3, the pipe 3 passes through the notch; when the light-shielding sheet 12 is parallel to the pipe 3, the extension parts 14 of the two light-shielding sheets 12 of the same light-shielding part 1 are connected to each other, so that the light-shielding part 1 can completely block light.

[0077] Preferably, an absorbing coating is applied on the side of the light-shielding sheet 12 facing the light source. The absorbing coating can prevent light reflection and convert light into heat energy to ensure the heat supply of the light-shielding sheet 12 to the pipe 3.

[0078] Compared with Embodiment 1, the building component of this embodiment uses a light-shielding sheet 12, so that the light-shielding area of the light-shielding part 1 is increased; when the light-shielding sheet 12 is connected to the pipeline 3, the heat-transfer sheet 13 can also be completely connected to the pipeline 3, increasing the efficiency of heat transfer from the light-shielding sheet 12 to the pipeline 3; when the light-shielding sheet 12 is parallel to the pipeline 3, the extension parts 14 of the two light-shielding sheets 12 of the same light-shielding part 1 are connected to each other, so that the light-shielding part 1 can be completely shielded from light.

[0079] Embodiment 3

[0080] Another embodiment of the present invention discloses another building component with adjustable light transmittance. Compared with Embodiment 2, the structure of the light-shielding part 1 is improved.

[0081] Preferably, as Figure 7 shown, the blade 11 is replaced by a push-pull assembly 15, and the light-shielding sheet 12 is connected to the push-pull assembly 15. The light-shielding sheet 12 can maintain an arbitrary angle with the pipeline 3 between two extreme states including perpendicular to the pipeline 3 and parallel and completely fitting the pipeline 3, so that the light-shielding area of the light-shielding part 1 can be adjusted arbitrarily from the minimum to complete light shielding.

[0082] Preferably, as Figure 8 shown, the push-pull assembly 15 includes a push-pull wire 151, a cross bar 152, a bracket 153 and a sleeve 154. The cross bar 152 is respectively connected to the push-pull wire 151 and the bracket 153, and the sleeve 154 is arranged on the push-pull wire 151.

[0083] Preferably, the bracket 153 includes two half brackets, and the two half brackets are respectively fixedly connected to the two ends of the cross bar 152. The push-pull wire 151 is wound around the cross bar 152 in a spiral structure, and the outer diameter of the cross bar 152 is the same as the inner diameter of the spiral structure. The cross bar 152 prevents the diameter of the spiral structure from becoming smaller; the two ends of the spiral structure are close to the side walls of the half brackets. The inner diameter of the sleeve 154 is the same as the outer diameter of the spiral mechanism, and the sleeve 154 prevents the diameter of the spiral mechanism from becoming larger. Grooves are provided at both ends of the sleeve 154, and the push-pull wire 151 can pass through the grooves. The two ends of the push-pull wire 151 are respectively connected to the light-shielding sheet 12. When the temperature rises, the push-pull wire 151 will elongate; when the temperature drops, the push-pull wire 151 will shorten. When the push-pull wire 151 elongates, it will push the light-shielding sheet 12 towards the pipeline 3; when the push-pull wire 151 shortens, it will pull the light-shielding sheet 12 in a direction perpendicular to the pipeline 3.

[0084] The push-pull wire 151 is made of steel, and the coefficient of thermal expansion of steel is 11, that is, at room temperature, for every 1°C change in temperature, the length of a 1m long steel wire changes by 0.0118mm. During the process of the temperature increasing from 20°C to 70°C, the length of a 4m long push-pull wire 151 can be increased by 2.36mm, that is, each end of the push-pull wire 151 elongates by 1.18mm, which is sufficient to push the light-shielding sheet 12 to rotate.

[0085] Preferably, the push-pull wire 151 is a magnesium alloy wire with a material model of AZ91D, and the coefficient of thermal expansion of AZ91D is 26. During the process of the temperature increasing from 20°C to 70°C, the length of the 2m long push-pull wire 151 can increase by 2.6mm, that is, each end of the push-pull wire 151 elongates by 1.3mm. Compared with the steel wire, the total length of the magnesium alloy wire push-pull wire 151 is greatly reduced, and the space of the light-shielding part 1 can be saved more effectively.

[0086] Preferably, connectors 155 are provided at both ends of the push-pull wire 151. The two ends of the push-pull wire 151 are connected to the light-shielding sheet 12 through the connectors 155. In this embodiment, the connectors 155 are circular rings or hooks.

[0087] Preferably, a rotating shaft hole 156 is provided at one end of the bracket 153. As Figure 9 shown, a first shaft 16 is provided at one end of the light-shielding sheet 12 close to the notch. The first shaft 16 can pass through the rotating shaft hole 156, so that the light-shielding sheet 12 can rotate around the first shaft 16 on the bracket 153.

[0088] Preferably, a shaft seat 17 and a second shaft 18 are further provided on the light-shielding sheet 12. The second shaft 18 is fixedly connected to the shaft seat 17. The second shaft 18 is parallel and in the same direction as the first shaft 16. The connector 155 is rotatably connected to the second shaft 18. Through the connector 155, the push-pull wire 151 can push and pull the second shaft 18, so that the light-shielding sheet 12 rotates around the first shaft 16 on the bracket 153.

[0089] Preferably, as Figure 10 shown, when the light-shielding sheet 12 is parallel to the pipeline 3, the extension parts 14 of the two light-shielding sheets 12 of the same light-shielding part 1 are connected to each other, so that the light-shielding part 1 can completely block light; the adjacent light-shielding parts 1 of two adjacent pipelines 3 can also be connected to each other, so that the overall light transmittance of the building component in this embodiment is minimized.

[0090] In this embodiment, the controller can control the rotation speed of the pump according to the light transmittance data transmitted by the light sensor and the temperature data transmitted by the temperature sensor, so as to control the flow rate of the coolant in the pipeline 3, change the heat exchange efficiency between the pipeline 3 and the light-shielding sheet 12, and further regulate the temperature of the pipeline 3, change the total length of the push-pull wire 151, control the angle between the light-shielding sheet 12 and the pipeline 3, that is, control the area of the light-blocking area, and finally control the light transmittance of the building component in this embodiment. The controller can arbitrarily control the angle between the light-shielding sheet 12 and the pipeline 3 between the two extreme states where the light-shielding sheet 12 is perpendicular to the pipeline 3 and parallel and completely attached to the pipeline 3, so that the light-blocking area of the light-shielding part 1 can be arbitrarily adjusted from the minimum to complete light blocking.
