[0007] The baffle comprises a baffle body, the baffle body comprises a first baffle member and a second baffle member, the first baffle member and the second baffle member are arranged side by side along the arrangement direction, the upper and lower ends of the first baffle member and the second baffle member are connected together, and the expansion rate of the first baffle member is less than the expansion rate of the second baffle member.

[0008] In some embodiments, the baffle comprises two baffle bodies arranged side by side along the arrangement direction, the lower ends of the two baffle bodies are connected together, the upper ends of the two baffle bodies are independent of each other, and the two second baffle members of the baffle are located between the two first baffle members; or the baffle comprises only one baffle body, and the first baffle members of the two adjacent baffle bodies are located on the same side or different sides of the connected second baffle members.

[0011] In some embodiments, the sun-shading temperature-regulating device comprises an exhaust device in communication with the interior of the building to exhaust air in the building when the temperature in the building is higher than a preset value.

[0012] In some embodiments, the sun-shading and temperature-regulating device comprises a temperature sensor arranged in the building to detect the temperature in the building, and the air exhaust device is configured to exhaust the air in the building when the temperature sensor detects that the temperature in the building is higher than a preset value.

[0013] In some embodiments, the plurality of baffles are rotatably connected to the support, and the sun-shading and temperature-regulating device comprises a driving mechanism drivingly connected to the light-blocking device and configured to rotate the plurality of baffles to change the intensity of sunlight entering the building through the glass roof by adjusting the angle of the plurality of baffles.

[0014] In some embodiments, the light-blocking device comprises a connecting rod hingedly connected to the plurality of baffles, and the driving mechanism is drivingly connected to the connecting rod and configured to rotate the plurality of baffles by driving the connecting rod to move.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without carrying out creative work fall within the scope of protection of the present application.

[0047] In the description of the present application, it should be understood that the use of the words "first", "second" and the like to define parts is only for the convenience of distinguishing the corresponding parts, and the above words have no special meaning unless otherwise stated, therefore cannot be understood as a limitation on the scope of protection of the present application.

[0048] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as there is no conflict.

[0049] Buildings such as office buildings use glass roofs, which are more beautiful and bright. However, the glass roof cannot be shaded, which leads to the sunlight directly entering the indoor in some cases, especially in hot summer, causing the indoor temperature to rise sharply, resulting in poor indoor environmental comfort, and causing energy waste when using air conditioning to cool.

[0050] In view of the above, the present application provides a shading and temperature regulating device and a control method thereof to shade the glass roof, reduce the solar radiation of the glass roof, and thus improve the comfort of the indoor environment and reduce energy waste.

[0051] Figures 1-8 The structure and working process of the shading and temperature regulating device of the present application are exemplarily shown.

[0052] Referring to Figures 1-8 In the present application, the shading and temperature regulating device 10 comprises a support 1 and a light blocking device 2. The support 1 is arranged above the glass roof 30 of the building 20. The light blocking device 2 comprises a plurality of baffles 22, which are arranged on the support 1 and are arranged side by side at intervals along the arrangement direction P. Moreover, the baffle 22 comprises a plate body 23, which comprises a first plate piece 24 and a second plate piece 25, the first plate piece 24 and the second plate piece 25 are arranged side by side along the arrangement direction P, the upper and lower ends of the first plate piece 24 and the second plate piece 25 are connected together, and the expansion rate of the first plate piece 24 is less than that of the second plate piece 25.

[0053] In the above arrangement, the baffles 22 are not made of the same material, but are made of materials with different expansion rates.

[0054] Because the first plate piece 24 and the second plate piece 25 of the baffle 22 connected side by side along the arrangement direction P have different expansion rates, the expansion rate of the first plate piece 24 is less than that of the second plate piece 25, therefore, when the temperature rises under the irradiation of the sun 40, the first plate piece 24 and the second plate piece 25 will expand to different degrees, among which the second plate piece 25 with a larger expansion rate expands more, the first plate piece 24 with a smaller expansion rate expands less, and the second plate piece 25 with a larger expansion rate will bend the first plate piece 24 with a smaller expansion rate, so that, referring to Figure 2 and Figure 3 The plate body 23 of the baffle 22 can bend as a whole to the side where the first plate piece 24 with a lower expansion rate is located, so that the plate body 23 can play a certain shading effect on the sunlight 50, reducing the direct sunlight 50 on the glass roof 30, thereby improving the comfort of the indoor environment and reducing energy waste.

[0055] Moreover, since the difference in expansion amount between the second plate member 25 and the first plate member 24 becomes larger as the temperature rises, the degree of bending of the plate body 23 toward the first plate member 24 side becomes larger as the temperature rises, and thus, as the solar elevation angle θ (i.e., the angle between the direction of sunlight at a certain location on the earth and the horizontal plane) increases and the outdoor temperature rises, the degree of bending of the plate body 23 toward the first plate member 24 side can increase, the shading area can increase, and the shading effect can be enhanced, thereby enabling the shading degree of the baffle 22 to be self-adjusted according to the solar elevation angle and the outdoor temperature, and facilitating the sun-shading and temperature-regulating device 10 to self-adjust the shading area according to the actual illumination and temperature, to control the indoor light intensity and temperature to be in an optimal state, and to further more effectively improve the comfort of the indoor environment and reduce energy waste.

[0056] As can be seen, by providing the baffle 22 including the first plate member 24 and the second plate member 25 with different expansion rates above the glass roof 30, not only can the sun-shading of the glass roof 30 be achieved, but also the self-adjustment of the sun-shading effect of the glass roof according to the illumination and temperature can be achieved, the structure is simple, the use is convenient, the sun-shading effect is good, the solar radiation of the glass roof 30 can be effectively reduced, the indoor environment is more comfortable, and the air conditioning energy consumption is less.

[0057] The first plate member 24 and the second plate member 25 can be made of various materials, as long as the expansion rate of the first plate member 24 is less than that of the second plate member 25. As an example, the first plate member 24 is made of iron, and the second plate member 25 is made of copper. Since the expansion rate of iron is less than that of copper, the first plate member 24 made of iron has a smaller expansion rate than the second plate member 25 made of copper, which facilitates the baffle 22 to self-change the degree of bending and adjust the sun-shading effect according to the changes in illumination and temperature.

[0058] In addition, the baffle 22 can include only one plate body 23, or can include more than one plate body 23.

[0059] When the baffle 22 includes only one plate body 23, the first plate 24 of the two adjacent plate bodies 23 can be arranged on the same side or different sides of the second plate 25. When the baffle 22 includes only one plate body 23, and the first plate 24 of the two adjacent plate bodies 23 is arranged on the same side of the second plate 25 (for example, the first plate 24 of the two adjacent plate bodies 23 is arranged on the left side of the connected second plate 25), the two adjacent baffles 22 bend towards the same side when the light is warmed, which can to some extent play a role in shading and reducing heat radiation. When the baffle 22 includes only one plate body 23, and the first plate 24 of the two adjacent plate bodies 23 is arranged on the different sides of the second plate 25 (for example, the first plate 24 of one of the two adjacent plate bodies 23 is arranged on the left side of the connected second plate 25, and the first plate 24 of the other plate body 23 is arranged on the right side of the connected second plate 25), the two adjacent baffles 22 bend towards opposite directions when the light is warmed, which can also to some extent play a role in shading and reducing heat radiation.

[0060] When the baffle 22 includes more than one plate body 23, it is convenient to further improve the shading effect. For example, referring to Figure 2 and Figure 3 In some embodiments, the baffle 22 includes two plate bodies 23, the two plate bodies 23 are arranged side by side along the arrangement direction P, and the lower ends of the two plate bodies 23 are connected together, while the upper ends are independent of each other, and the second plate 25 of the two plate bodies 23 is close to the other plate body 23 relative to the first plate 24.

[0061] Based on the above arrangement, the two second plates 25 of the same baffle 22 are located between the two first plates 24, and the two first plates 24 of the same baffle 22 are located on the outside and adjacent to other baffles 22, so that when the light is warmed, referring to Figure 2 and Figure 3 , the two plate bodies 23 of the same baffle 22 bend towards opposite directions, and the two plate bodies 23 of the two adjacent baffles 22 that are close to each other bend towards each other, so that between any two baffles 22, they can be shaded by two bent plate bodies 23, the shading area is larger, the shading effect is better, and the direct sunlight can be more effectively reduced, and the heat load can be reduced.

[0062] In addition to the shading and temperature regulating device 10 can be arranged to include the first plate 24 and the second plate 25 with different expansion rates to achieve the shading effect of the shading and temperature regulating device 10 and reduce the heat radiation of the glass roof 30, other means can also be used to achieve the shading effect of the shading and temperature regulating device 10 and reduce the heat radiation of the glass roof 30.

[0063] For example, referring to Figure 1 and Figures 4-8In some embodiments, all the baffles 22 of the light blocking device 2 are rotatably connected to the support 1, and the sunshade and temperature regulating device 10 comprises a driving mechanism 3, which is drivingly connected with the light blocking device 2 and drives the rotation of each baffle 22 to change the intensity of sunlight 50 shining into the building 20 through the glass roof 30 by adjusting the angle of each baffle 22.

[0064] Based on the above arrangement, in different seasons, different light conditions, and different temperature conditions, the driving mechanism 3 can be used to adjust the baffles 22 to different angles to control whether to shade and the size of the shading area, so that different requirements for lighting and light blocking can be flexibly met, and when shading is needed, the direct sunlight can be better reduced and the heat radiation can be more effectively reduced.

[0065] For example, in the morning and afternoon, when the sunlight is oblique, the driving mechanism 3 can be used to adjust the angle of the baffles 22 to effectively block the sunlight 50 and reduce the direct sunlight of the sunlight 50 on the glass roof 30, thereby achieving the effect of cooling and energy saving; and in other time periods, the baffles 22 can be kept as upright as possible to maintain good lighting and good vision of the glass roof 30.

[0066] As can be seen, by setting the baffles 22 to be angle-adjustable and setting the driving mechanism 3 to adjust the angle of the baffles 22, the shading of the glass roof 30 and the automatic adjustment of the shading effect can also be achieved.

[0067] In order to facilitate the driving mechanism 3 to adjust the angle of the baffles 22, see Figure 1 In some embodiments, the light blocking device 2 comprises a connecting rod 21, which is hingedly connected with each baffle 22, and the driving mechanism 3 is drivingly connected with the connecting rod 21 and drives the movement of the connecting rod 21 to drive the rotation of the plurality of baffles 22. Based on this, only the movement of the connecting rod 21 needs to be driven to drive all the baffles 22 of the light blocking device 10 to rotate together to change the light blocking angle, which is simple and convenient, and the rotation of each baffle 22 is better synchronized, thereby facilitating the realization of a more uniform and controllable shading effect.

[0068] As an example of the driving mechanism 3, see Figure 1 In some embodiments, the driving mechanism 3 comprises a cam 31, the driving mechanism 3 is connected with the connecting rod 21 through the cam 31, and the cam 31 drives the movement of the connecting rod 21 when it rotates.

[0069] By using the cam 31, the connecting rod 21 can be conveniently driven to move, thereby driving all the baffles 22 to rotate relative to the support 1 to change the angle of all the baffles 22, which is simple in structure and convenient to adjust.

[0070] In addition, see Figure 1In some embodiments, the sun-shading and temperature-regulating device 10 comprises a timing controller 4, which is in signal connection with the driving mechanism 3 to control the driving mechanism 3 to adjust the angle of the baffle 22.

[0071] The timing controller 4 is a controller capable of controlling the running time of a program and the sequence of operation. The timing controller 4 is arranged to control the driving mechanism 3, so as to facilitate the orderly operation of the driving mechanism 3, and to adjust the angle of the baffle 22 according to the change of the solar altitude angle in a day, so that the baffle 22 can be rotated to different angles at different times of the day, to more effectively shade and cool.

[0072] As mentioned above, the angle of the baffle 22 is adjustable, and the baffle 22 comprises the first plate member 24 and the second plate member 25 with different expansion rates. Both of these two ways can achieve the purpose of shading and cooling, effectively reducing the thermal load of the glass roof 30. Therefore, in specific implementation, these two ways can be used at the same time, or only one of them can be used. For example, in some embodiments, the baffle 22 comprises the first plate member 24 and the second plate member 25 with different expansion rates, but the angle is not adjustable; or, in some other embodiments, the angle of the baffle 22 is adjustable, but the baffle 22 does not comprise the first plate member 24 and the second plate member 25 with different expansion rates; or, in some other embodiments, the angle of the baffle 22 is adjustable, and the baffle 22 comprises the first plate member 24 and the second plate member 25 with different expansion rates. Among them, when the angle of the baffle 22 is adjustable, and the baffle 22 comprises the first plate member 24 and the second plate member 25 with different expansion rates, the sun-shading and temperature-regulating device 10 can achieve better shading effect, and can better balance the different needs of lighting and shading.

[0073] In addition, other ways can also be used to balance the different needs of lighting and shading. For example, in some embodiments, the support 1 is movably or telescopically arranged above the glass roof 30 to drive the light-blocking device 2 to move between the first position and the second position. When in the first position, the light-blocking device 2 shields the glass roof 30, and when in the second position, the light-blocking device 2 unblocks the glass roof 30.

[0074] Based on the above arrangement, by controlling the movement or telescopic extension of the support 1, it is convenient to control whether the light-blocking device 2 shields the glass roof 30, so as to meet different needs of shading and lighting effect under different conditions. For example, in winter and other seasons with less radiant heat, the light-blocking device 2 can be controlled to move to the second position, so that the light-blocking device 2 no longer shields the glass roof 30, and the glass roof 30 can be directly exposed, so that the glass roof 30 has good lighting and vision. For another example, in summer and other seasons with more radiant heat, the light-blocking device 2 can be controlled to move to the first position, to shade the glass roof 30 by the light-blocking device 2, to reduce direct sunlight and reduce the thermal load.

[0075] When the support 1 is movably arranged above the glass roof 30, the support 1 drives the whole light blocking device 2 to move, so that when in the first position, the light blocking device 2 is located above the glass roof 30 to shield the glass roof 30, and when in the second position, the light blocking device 2 is moved to one side of the glass roof 30, so that the glass roof 30 is no longer shielded by the light blocking device 2 and is directly exposed.

[0076] When the support 1 is movably arranged above the glass roof 30, the support 1 can include a plurality of arm segments corresponding to the baffles 22 one by one, which are sequentially sleeved and can be relatively telescoped, so that the support 1 can be telescoped to drive all the baffles 22 of the light blocking device 2 to expand or fold, thereby controlling whether the light blocking device 2 plays a light blocking role. When all the arm segments are extended, the light blocking device 2 is expanded and in the first position, located above the glass roof 30 to shield the glass roof 30, and when all the arm segments are retracted, the light blocking device 2 is folded and in the second position, located at one side of the glass roof 30, so that the glass roof 30 is no longer shielded by the light blocking device 2 and is directly exposed.

[0077] In addition, in order to better control the temperature in the building 20, referring to Figure 1 In some embodiments, the sunshade temperature regulating device 10 includes an exhaust device 5, which is in communication with the inside of the building 20 to exhaust the air in the building 20 when the temperature in the building 20 is higher than a preset value.

[0078] Since the exhaust device 5 exhausts the air in the building 20, the indoor hot air can be exhausted, and the building 20 can be temporarily in a negative pressure state, so that outdoor air enters the indoor through doors and windows, etc., so that the ventilation cooling effect can be achieved, and the indoor temperature can be effectively reduced.

[0079] In order to facilitate the exhaust of the exhaust device 5, referring to Figure 1 In some embodiments, the sunshade temperature regulating device 10 includes a temperature measuring member 6 arranged in the building 20 to detect the temperature in the building 20, and the exhaust device 5 exhausts the air in the building 20 when the temperature measuring member 6 detects that the temperature in the building 20 is higher than a preset value.

[0080] Based on the temperature measurement result of the temperature measuring member 6, the exhaust of the exhaust device 5 can be more accurately controlled to ventilate and cool the indoor.

[0081] Next, the embodiments shown in Figures 1-8 will be further introduced.

[0082] As shown in Figures 1-8As shown, in this embodiment, the sunshade temperature regulating device 10 is used for cooling the building 20 with the glass roof 30, which comprises the support 1, the light blocking device 2, the driving mechanism 3, the time controller 4, the air exhaust device 5 and the temperature measuring element 6.

[0083] Wherein, the support 1, the light blocking device 2, the driving mechanism 3 and the time controller 4 cooperate with each other to reduce the indoor temperature by blocking the sunlight to the glass roof 30 to reduce the radiation amount of the sun 40. The air exhaust device 5 and the temperature measuring element 6 cooperate with each other to reduce the indoor temperature by ventilating the indoor. Thus, the sunshade temperature regulating device 10 of this embodiment can reduce the room temperature by using the two ways of blocking sunlight and ventilating, so that the problem of high radiation and high temperature caused by the glass roof 30 can be effectively solved while the advantages of the glass roof 30 such as beauty and brightness are retained.

[0084] Specifically, the support 1 is used for supporting the light blocking device 2. As shown in the figure, Figure 1 In this embodiment, the support 1 is roughly in the shape of a rod, which is arranged above the glass roof 30 and roughly parallel to the surface of the glass roof 30, and extends along the arrangement direction P. As can be seen from the figure, Figure 1 In this embodiment, the glass roof 30 is roughly horizontal flat roof, and the arrangement direction P is the east-west direction (i.e. the left-right direction of the figure). Figure 1

[0085] The light blocking device 2 is used for blocking the sunlight 50 and adjusting the radiation amount of the sunlight 50. As shown in the figure, in this embodiment, the light blocking device 2 is arranged on the support 1 and comprises the connecting rod 21 and a plurality of baffles 22. All the baffles 22 are arranged vertically and are hingedly connected to the support 1 at equal intervals along the arrangement direction P. Figure 1

[0086] Specifically, all the baffles 22 are solid, thin and corrosion-resistant lightproof plates, the thickness direction of which is along the east-west direction (i.e. the arrangement direction P), the length direction of which is along the north-south direction (i.e. the front-rear direction of the figure), and the height direction of which is along the up-down direction (i.e. the top-bottom direction of the figure). Figure 1 Figure 1 ​​​When the sun is in the east, the sun's rays are in the east-west direction, at this time, all the baffles 22 are vertically installed on the support 1, and the normal vectors of all the baffles 22 are parallel to the extension direction of the support 1. The distance between any two adjacent baffles 22 is equal, which is L. The height of each baffle 22 is the same, which is H. The smaller L is, the larger H is, which is more conducive to shading and light blocking. In this embodiment, L and H are both 20 cm. The lower end of each baffle 22 is hinged to the support 1 through a hinge 26, and the middle part of the height direction of each baffle 22 is hinged to the connecting rod 21 through a hinge 26, so that all the baffles 22 are rotatably connected to the support 1, and all the baffles 22 are hinged to the connecting rod 21, so that the connecting rod 21 drives all the baffles 22 to rotate synchronously relative to the support 1 through horizontal movement in the east-west direction, realizing synchronous adjustment of the angle of all the baffles 22.

[0087] In the length direction of the baffles 22, a plurality of supports 1 can be arranged at intervals to realize more stable support of the light blocking device 2.

[0088] Figure 2 Further, the structure of the baffle 22 is shown.

[0089] As shown in Figure 2 , in this embodiment, all the baffles 22 include two plate bodies 23, and each plate body 23 includes a first plate piece 24 and a second plate piece 25. The first plate piece 24 and the second plate piece 25 are respectively made of iron with a small expansion rate and copper with a large expansion rate, so that the plate body 23 becomes a bimetallic plate, which can bend towards the side of the first plate piece 24 with a small expansion rate when the temperature rises.

[0090] It can be known from Figure 1 and Figure 2 that, in this embodiment, for the same plate body 23, the first plate piece 24 and the second plate piece 25 are arranged side by side along the east-west direction and connected to each other, wherein the upper ends of the first plate piece 24 and the second plate piece 25 are connected together through a connecting piece 27 (such as a rivet 28). For any one baffle 22, the lower ends of the two plate bodies 23 are connected together, but the upper ends are not connected and are independent of each other, so that the upper ends of the two plate bodies 23 form free ends, which facilitates the two plate bodies 23 to bend in different directions when heated. Moreover, the relative positions of the first plate piece 24 and the second plate piece 25 of the two plate bodies 23 of the same baffle 22 are opposite, wherein the second plate piece 25 of one plate body 23 is located on the west side (right side in Figure 1 and Figure 2 ) of the first plate piece 24, and the second plate piece 25 of the other plate body 23 is located on the east side (left side in Figure 1 and Figure 2two second plate pieces 25 of the same baffle 22 are located between two first plate pieces 24, and the two second plate pieces 25 of any baffle 22 are opposite to each other, and the two first plate pieces 24 of any baffle 22 are opposite to each other.

[0091] Based on the above arrangement, when the temperature rises after being irradiated by the sun 40 (see Figure 4 ), as shown in Figure 2 , the two plate bodies 23 of any baffle 22 will bend towards the side where the first plate piece 24 with smaller expansion rate is located, so that the two plate bodies 23 of any baffle 22 bend in opposite directions, so that, as shown in Figure 3 , any two adjacent baffles 22 can be shielded by two bent plate bodies 23, and the sun-shading area is large, which can effectively reduce the width of the sunlight 50 irradiating onto the glass roof 30 and the radiation amount of the sunlight 50 on the glass roof 30, so that the heat radiation generated by the glass roof 30 can be effectively reduced, and a better sun-shading and cooling effect can be achieved.

[0092] Moreover, under the action of the first plate piece 24 and the second plate piece 25, the bending degree of the plate body 23 can increase with the increase of the temperature and decrease with the decrease of the temperature, so that the sun-shading effect can also be automatically adjusted according to the outdoor temperature based on the bending of the plate body 23. As an example, Figure 1 and Figure 3 respectively show the state of the light shielding device 2 when it is not heated and when it is heated. Among them, as shown in Figure 1 , when not heated, all baffles 22 remain in an upright state and are not bent, at which time better lighting and vision can be maintained; and as shown in Figure 3 , after heating, all baffles 22 are bent, so that the baffle 22 can shield the sunlight 50, reduce direct sunlight, and reduce the heat load.

[0093] It can be seen that by arranging the baffle 22 to automatically change the bending degree thereof according to the outdoor temperature, the self-adjustment of whether to shade and how much to shade can be realized, so that the direct sunlight can be effectively reduced and the indoor heat load can be reduced while the lighting and aesthetic functions of the glass roof 30 are taken into account.

[0094] Back to Figure 1 , the driving mechanism 3 is used to drive all baffles 22 to rotate together to adjust the angle of all baffles 22. As shown in Figure 1As shown, in this embodiment, the driving mechanism 3 comprises a cam 31 connected with the connecting rods 21, so that the cam 31 can rotate to drive the connecting rods 21 to move horizontally along the east-west direction, and further drive all the baffles 22 to rotate relative to the support 1, so as to adjust the angles of all the baffles 22, and automatically adjust the shading angles of the baffles 22 according to the change of the solar altitude angle θ, so as to prevent the sunlight from directly shining onto the glass roof 30 to the greatest extent.

[0095] The timing controller 4 is used to control the driving mechanism 3 to act in sequence, so as to control the driving mechanism 3 to automatically adjust the angles of the baffles 22 according to the change of the solar altitude angle θ. As shown in Figure 1 this embodiment, the timing controller 4 is electrically connected with the cam 31 of the driving mechanism 3, so that the cam 31 can orderly rotate under the control of the timing controller 4, and drive all the baffles 22 to change the angles according to the change of the solar altitude angle θ.

[0096] During a day, the sun 40 rises in the east and sets in the west, and the solar altitude angle θ changes constantly. According to this, in this embodiment, the driving mechanism 3 controls the baffles 22 to gradually deflect westward from the upright state under the control of the timing controller 4 according to the size relationship between tan θ and (i.e. the ratio of the baffle height to the baffle spacing), and then once deflected eastward to the maximum, and then gradually deflected westward until returning to the upright state.

[0097] The angle changes of the baffles 22 at different solar altitude angles θ during a day are further shown in Figures 4-8 . In order to more clearly show the angle changes of the baffles 22, Figures 4-8 only some of the baffles 22 in Figure 1 are shown, and the changes of the degrees of expansion and bending of each baffle 22 caused by temperature changes are not shown again.

[0098] Among them, Figure 4 the angles of the baffles 22 at are shown. As shown in Figure 4 , when the sun 40 rises in the morning, all the baffles 22 are in the upright state during the process from , so that the glass roof 30 has good utilization and vision.

[0099] Figure 5 The angles of the baffles 22 at are shown. As shown in Figure 5 , when the sun 40 continues to move westward, , with the increase of the solar altitude angle θ, the driving mechanism 3 drives all the baffles 22 to gradually tilt westward, so as to block the sunlight 50 as much as possible, and prevent the sunlight 50 from directly shining onto the glass roof 30, until Figure 6As shown, the solar altitude angle θ reaches 90°.

[0100] Figure 6 The image shows the angle at which the baffle 22 reaches 90° at the solar altitude angle θ. (As shown) Figure 6 As shown, around noon, when the solar altitude angle θ reaches 90°, all the baffles 22 tilt to the west at their maximum angle.

[0101] Figure 7 The baffle 22 is shown in The angle of time. For example... Figure 7 As shown, when the sun continues to move westward, At that time, the drive mechanism 3 drives all the baffles 22 to deflect eastward in one go until the angle between the baffle 22 and the normal of the glass roof 30 is . Try to prevent direct sunlight (50%) from hitting the glass roof (30%).

[0102] Figure 8 The baffle 22 is shown in The angle of time. As the sun continues to move westward, the baffle 22... Figure 7 The position of angle α shown gradually deflects westward until it reaches the position shown in the figure. Figure 8 As shown, The baffle 22 returns to its upright position.

[0103] It can be seen that by making the baffle 22 rotatable, the tilt of the baffle 22 can be controlled in the morning, noon, and afternoon when the sun is shining at a 40° angle, and the tilt can be adjusted according to tanθ and... By adjusting the size relationship between the two, the tilt angle is changed to block sunlight 50 to the maximum extent, reduce direct sunlight, and lower the heat load. At other times, the baffle 22 is kept upright to maintain good lighting and view. Thus, while taking into account the lighting and aesthetic functions of the glass roof 30, direct sunlight is effectively reduced and the indoor heat load is lowered.

[0104] In this embodiment, the baffle 22 is not only rotatable and angle-adjustable, but also expands and bends according to different outdoor temperatures. Therefore, the light-blocking device 2 can not only change the size of the shading area by changing the angle of the baffle 22, but also change the size of the shading area based on the change in the degree of bending of the baffle 22 itself. This can achieve a more effective shading and cooling effect.

[0105] And, in this embodiment, the support 1 supporting the light blocking device 2 is configured to be retractable, so that when the support 1 is retracted, all the baffles 22 are brought to be unfolded or folded, and the light blocking device 2 is controlled to shield or unshield the glass roof 30. Thus, in the summer and other seasons with high radiation heat, the support 1 can be controlled to be extended, so as to play the sun-shading role of the light blocking device 2 and reduce the heat load. In the winter and other seasons with low radiation heat, the support 1 can be controlled to be retracted, so as to drive the light blocking device 2 to move to the side of the glass roof 30 and unshield the glass roof 30, so that the indoor has better lighting and view.

[0106] It can be seen that, under the cooperation of the support 1, the light blocking device 2, the driving mechanism 3 and the time sequence controller 4, the sun-shading and temperature-regulating device 10 of this embodiment can not only meet different sun-shading requirements at different times of a day, but also meet different sun-shading requirements in different seasons of a year, and has strong work flexibility and can realize the comprehensive effect of maximum light shielding, lighting and view.

[0107] Returning to Figure 1 , the temperature measuring member 6 is used to detect the indoor temperature, and the air exhausting device 5 is used to exhaust and ventilate the indoor according to the detection result of the temperature measuring member 6, so as to ventilate and cool the indoor. As shown in Figure 1 , in this embodiment, the air exhausting device 5 includes a fan 51 and an air pipe 52, and the fan 51 communicates the indoor with the outdoor through the air pipe 52, so as to exhaust the indoor air to the outdoor when needed. The temperature measuring member 6 includes a thermometer 61, which is arranged below the glass roof 30 and close to the lower surface of the glass roof 30, so as to detect the temperature close to the lower surface of the glass roof 30.

[0108] When the thermometer 61 detects that the indoor temperature exceeds the outdoor temperature, the fan 51 is started to exhaust part of the indoor air to the outdoor, so as to timely exhaust the heat radiated to the indoor. At the same time, in the process of exhausting, the air with lower temperature outside enters the indoor through the doors and windows due to the temporary negative pressure state in the indoor, so as to reduce the indoor temperature.

[0109] Since the hot air rises and gathers close to the lower surface of the glass roof 30 in the indoor, the thermometer 61 is arranged close to the lower surface of the glass roof 30 in the indoor, so as to timely detect the high temperature caused by the radiation of the glass roof 30, so as to timely control the start and stop of the fan 51 and ventilate and exchange the air in the indoor, so as to reduce the indoor temperature.

[0110] Since the sun-shading and temperature-regulating device 10 of this embodiment can not only perform sun-shading and cooling based on the cooperation of the support 1, the light blocking device 2, the driving mechanism 3 and the time sequence controller 4, but also perform ventilation and cooling based on the cooperation of the air exhausting device 5 and the temperature measuring member 6, the cooling mode is more flexible and the cooling effect is better.

[0111] It should be noted that although Figures 1-8 The embodiment shown in the drawings is described by taking the flat glass roof 30 as an example, but the sun-shading and temperature-regulating device 10 of the present application is not limited to the case of the flat glass roof 30, and can also be applied to the case of the pointed or round glass roof 30.

[0112] In addition, for the sun-shading and temperature-regulating device 10 including the driving mechanism 3 and the rotatable baffle 22, the present application also provides a control method, which includes:

[0113] determining the solar altitude angle θ; and

[0114] According to the size relationship between tanθ and , the driving mechanism 3 is used to drive the plurality of baffles 22 to rotate, wherein H is the height of the baffle 22, and L is the distance between the adjacent two baffles 22.

[0115] Specifically, in some embodiments, according to the size relationship between tanθ and , the driving mechanism 3 is used to drive the plurality of baffles 22 to rotate, including at least one of the following:

[0116] When , the plurality of baffles 22 are all in the upright state;

[0117] When , the driving mechanism 3 is used to drive the plurality of baffles 22 to deflect to the right;

[0118] When , the driving mechanism 3 is used to drive the plurality of baffles 22 to deflect to the left once, so that the included angle between the plurality of baffles 22 and the normal line of the glass roof 30 is Then, as the sun moves to the west, the plurality of baffles 22 gradually deflect to the west until the plurality of baffles 22 return to the upright state.

[0119] The above only describes exemplary embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
