Technical Field

[0001] The present invention relates to the technical field of roof structures, and in particular to a roof unit, a roof system and a building. Background Art

[0002] In order to meet users' increasingly diverse requirements for building functions, building designs are becoming more and more complex, and both design and construction costs are increasing. Therefore, how to simplify building design while meeting diverse usage needs has become a major issue that needs to be solved urgently. Summary of the Invention

[0003] The embodiments of the present invention disclose a roof unit, a roof system and a building, which can realize multiple functions to meet multiple usage requirements through the roof unit and the roof system, thereby eliminating the need for complex designs in other structures of the building and achieving the effect of simplifying the design of the building.

[0004] In order to achieve the above object, the present invention discloses a roof unit, comprising:

[0005] a bracket, the bracket comprising a first frame body and a second frame body, the first frame body comprising a first top portion and a first bottom portion opposite to each other, the second frame body being spaced apart from the first frame body to form a light-transmitting space therebetween;

[0006] Roof glass, two sides of which are respectively connected to the first top of the first frame and the second frame, and the roof glass is located in the light-transmitting space to cover the opening of the light-transmitting space;

[0007] a shielding member connected to the first top portion of the first frame and located on a side of the first frame facing away from the light-transmitting space, the shielding member having a first surface facing the first bottom portion of the first frame, the first surface being at least partially formed as a light-reflecting surface; and

[0008] A light emitting component is provided at the first bottom of the first frame and is located on a side of the first frame away from the light-transmitting space, with a light emitting end of the light emitting component facing the first surface.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] The roof unit, roof system, and building provided by the embodiments of the present invention utilize roof glass to seal an opening, thereby achieving both the roof unit's function of separating the building's interior from the exterior and daylighting the interior of the building. Furthermore, by providing a shielding member, the light-emitting member can be shielded, making it difficult for users to observe the light-emitting member from the exterior of the building, thereby simplifying the building's roof structure and preventing wind and rain from directly affecting the light-emitting member, thereby extending the light-emitting member's service life. Furthermore, by directing the light-emitting member toward the first surface of the shielding member, the light emitted by the light-emitting member can be reflected by the first surface and then evenly illuminated by the roof glass, achieving a uniform lighting effect. Furthermore, by combining the light-transmitting function of the roof glass, the roof's exterior can be illuminated while also providing a certain degree of interior lighting. Thus, the roof unit provided by the present application can achieve multiple different functions, such as space partitioning, daytime natural lighting, uniform exterior lighting of the roof, interior lighting of the building, and a simple roof. By integrating multiple building functions into the roof unit, the overall design and construction of the building can be simplified, reducing the difficulty and cost of overall building design.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0040] In the present invention, terms such as "upper," "lower," "left," "right," "front," "back," "top," "bottom," "inner," "outer," "center," "vertical," "horizontal," "transverse," and "longitudinal" indicate positions or locations based on the positions or locations shown in the accompanying drawings. These terms are primarily intended to better describe the present invention and its embodiments and are not intended to limit the devices, elements, or components indicated to having a specific orientation, or to being constructed or operated in a specific orientation.

[0041] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to indicate a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0042] Furthermore, the terms "installed," "disposed," "provided with," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on specific circumstances.

[0043] Furthermore, the terms "first," "second," etc., are primarily used to distinguish between different devices, elements, or components (which may or may not be of the same type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0044] To meet users' increasingly diverse functional requirements for buildings, building designs are becoming increasingly complex, and both design and construction costs are rising. To achieve a building's multiple functions (such as external lighting, ventilation, and smoke exhaust), the building needs to be equipped with a variety of corresponding functional structures (such as lighting fixtures on the exterior or perimeter of the building, or smoke exhaust ducts inside the building and smoke exhaust vents connected to the ducts). This complicates the building's structure and increases design and construction costs.

[0045] Based on this, the present application provides a roof unit, a roof system and a building, which integrates multiple functions into the roof unit to replace other functional structures in the building, thereby simplifying the overall design of the building and reducing the overall design cost of the building.

[0046] The technical solution of the present invention will be further described below in conjunction with embodiments and drawings.

[0047] Please also refer to Figures 1 to 3 , Figure 1 This is a structural diagram of the roof unit disclosed in the first aspect of the embodiment of this application. Figure 2 yes Figure 1 A cross-sectional view along the AA direction, Figure 3 yes Figure 2As shown in the enlarged schematic diagram at point C in FIG, the first aspect of the embodiment of the present application discloses a roof unit 1, comprising: a bracket 10, roof glass 11, a shielding member 12, and a light-emitting member 13. The bracket 10 includes a first frame 100 and a second frame 101. The first frame 100 includes a first top 100a and a first bottom 100b opposite to each other. The second frame 101 is spaced apart from the first frame 100, and a light-transmitting space 102 is formed therebetween. The roof glass 11 is connected to the first top 100a of the first frame 100 and the second frame 101 on both sides, respectively. The roof glass 11 is located in the light-transmitting space 102 to cover the opening 102a of the light-transmitting space 102. The shielding member 12 is connected to the first top portion 100a of the first frame 100 and is located on a side of the first frame 100 facing away from the light-transmitting space 102. The shielding member 12 has a first surface 12a facing the first bottom portion 100b of the first frame 100. The first surface 12a is at least partially formed as a reflective surface. The light-emitting member 13 is disposed on the first bottom portion 100b of the first frame 100 and is located on a side of the first frame 100 facing away from the light-transmitting space 102. The light-emitting end of the light-emitting member 13 faces the reflective surface.

[0048] Specifically, by using the roofing glass 11 to close the opening 102a, the roof unit 1 not only achieves its function of separating the building's interior from the exterior, but also provides daylighting inside the building. Simultaneously, by providing the shielding member 12, the light-emitting member 13 can be shielded, making it difficult for users to observe the light-emitting member 13 from the exterior of the building, thereby simplifying the building's roof structure and preventing wind and rain from directly affecting the light-emitting member 13, thereby protecting the light-emitting member 13. Furthermore, by emitting light from the light-emitting member 13 toward the first surface 12a of the shielding member 12, the light emitted by the light-emitting member 13 can be reflected by the first surface 12a and then evenly illuminated by the roofing glass 11, achieving a uniform lighting effect. Furthermore, in conjunction with the light-transmitting function of the roofing glass 11, a certain degree of internal lighting can be achieved while simultaneously illuminating the roof's exterior.

[0049] It can be seen that the roof unit 1 provided in the embodiment of the present invention can realize a variety of different functions, such as space partition function, daytime natural lighting function, uniform lighting function on the roof surface, internal lighting function of the building and simple effect of the roof. By integrating the various functions of the building into the roof unit 1, the overall design and construction of the building can be simplified, and the difficulty and cost of the overall design and construction of the building can be reduced.

[0050] It can be understood that in order to further improve the sealing and waterproof performance of the roof unit 1, the various components included in the roof unit 1 (such as between the roof glass 11 and the bracket 10, between the first frame 100 and the second frame 101, between the shielding member 12 and the first frame 100, between the light-emitting member 13 and the first frame 100, etc.) can be filled or coated with silicone weather-resistant sealant 14a to fill and seal the gaps between the various components included in the roof unit 1.

[0051] Next, the structures of various parts of the roof unit 1 will be described in detail with reference to the accompanying drawings.

[0052] Please also refer to Figures 2 to 4 In some embodiments, the first frame 100 and the second frame 101 are both long hollow rod structures made of hollow profiles (such as hollow aluminum profiles or stainless steel profiles), so that it is easy to use the first frame 100 and the second frame 101 to form a bracket 10 structure, so that the bracket 10 can be used to bear a certain weight, and at the same time, the overall weight of the bracket 10 can be reduced, thereby reducing the weight of the roof unit 1 and reducing the load on the building.

[0053] Optionally, the first frame 100 and the second frame 101 extend in the same direction. In other words, the first frame 100 and the second frame 101 are arranged in parallel, so that the shape of the bracket 10 is more regular and the bracket 10 is easier to manufacture and assemble.

[0054] In some embodiments, the first top 100a of the first frame 100 has a first bearing surface 100d, which is located on the side of the roof glass 11 facing the opening 102a, and the first bearing surface 100d is connected to the roof glass 11. By supporting the roof glass 11 through the first bearing surface 100d, the connection area between the first frame 100 and the roof glass 11 can be increased, thereby enhancing the supporting stability of the first frame 100 on the roof glass 11, reducing the pressure at the connection between the first frame 100 and the roof glass 11, avoiding damage to the roof glass 11 due to excessive local force, and improving the safety of the roof unit 1.

[0055] In some embodiments, the second top 101a of the second frame 101 has a second bearing surface 101d, which is located on the side of the roof glass 11 facing the opening 102a, and the second bearing surface 101d is connected to the roof glass 11. By supporting the roof glass 11 through the second bearing surface 101d, the connection area between the second frame 101 and the roof glass 11 can be increased, thereby enhancing the supporting stability of the second frame 101 on the roof glass 11, reducing the pressure at the connection between the second frame 101 and the roof glass 11, avoiding the roof glass 11 from being damaged due to excessive local force, and improving the safety of the roof unit 1.

[0056] Optionally, the first bottom 100b of the first frame 100 may be provided with a first connecting portion 100c, and the second frame 101 also includes a second bottom 101b opposite to the second top 101a, and the second top 101a may be provided with a second connecting portion 101c, the first connecting portion 100c is used to cooperate and connect with the second connecting portion 101c included in other roof units 1 (for example, adjacent roof units 1), and the second connecting portion 101c is used to cooperate and connect with the first connecting portion 100c included in other roof units 1 (for example, adjacent roof units 1), thereby realizing the function of connecting the roof unit 1 with other roof units 1, that is, different roof units 1 only need to be provided with corresponding first connecting portions 100c and second connecting portions 101c to achieve mutual connection, the structural flexibility of the roof unit 1 is high, and the adaptability between each roof unit 1 is good.

[0057] Specifically, one of the first connection part 100c and the second connection part 101c includes a protrusion, and the other includes a recess, that is, the first connection part 100c includes a recess and the second connection part 101c includes a protrusion, or the first connection part 100c includes a protrusion and the second connection part 101c includes a recess. By matching the protrusion with the recess, the first connection part 100c and the second connection part 101c are matched and connected. The connection effect is stable, the structure is simple, the connection operation is simple, and it is convenient to quickly splice multiple roof units 1.

[0058] Furthermore, if Figures 3 to 5 As shown, Figure 5 The figure shows the local structure of the first connecting part 100c and the second connecting part 101c respectively included in two adjacent roofing units 1 when they are connected. Taking the example of the first connecting part 100c including a recess and the second connecting part 101c including a protrusion, one end of the second connecting part 101c is formed as a protrusion, and a damping seal 140 is provided on the protrusion. The end of the damping seal 140 facing away from the protrusion is used to interfere with the surface of the first connecting part 100c facing the recess, so as to generate resistance when there is a tendency for phase separation between the first connecting part 100c and the second connecting part 101c, thereby preventing the first connecting part 100c and the second connecting part 101c from separating, thereby improving the stability of the connection between the two adjacent roofing units 1. At the same time, the damping seal 140 can also be used to separate in the gap between the first connecting part 100c and the second connecting part 101c to achieve a waterproof sealing effect. It is understandable that, in other embodiments, the damping seal 140 may also be disposed in the recess, that is, the damping seal 140 may be disposed on the first connecting portion 100 c .

[0059] Optionally, the damping seal 140 can be a sealing strip made of an elastic, water-impermeable and air-permeable material such as EPDM (Ethylene Propylene Diene Monomer) plastic or rubber, so that the damping seal 140 can be installed between the first connecting part 100c and the second connecting part 101c in an interference fit manner, thereby preventing water and air from flowing in the gap between the first connecting part 100c and the second connecting part 101c, thereby achieving a waterproof sealing effect.

[0060] Optionally, there may be multiple damping seals 140, which are spaced apart. By increasing the number of damping seals 140, the connection areas between the damping seals 140 and the first connection portion 100c and the second connection portion 101c can be increased, thereby improving the damping effect of the damping seals 140 and improving the connection stability between the first connection portion 100c and the second connection portion 101c. Figure 4 and Figure 5 As shown, for example, there may be two damping seals 140, which are respectively arranged on two opposite sides of the second connection part 101c, so that the gap between the second connection part 101c and the first connection part 100c can be blocked and sealed from both sides of the second connection part 101c. The rebound force generated by the two damping seals 140 due to being squeezed is more balanced, so that the sealing and waterproofing effects achieved by the two damping seals 140 are similar, and the structure of the roof unit 1 is more balanced and reasonable.

[0061] See also Figure 6 , Figure 6 This is a structural cross-sectional view of the roof unit 1 disclosed in the first aspect of the embodiment of the present application when the roof glass 11 is in a covering posture. In some embodiments, the second frame 101 and / or the first frame 100 may be formed with a first drainage channel 105, and the extension direction of the first drainage channel 105 is the same as the extension direction of the second frame 101 and the first frame 100. In other words, the second frame 101 may be formed with the first drainage channel 105, or the first frame 100 may be formed with the first drainage channel 105, or both the first frame 100 and the second frame 101 may be formed with the first drainage channel 105, so that the first drainage channel 105 can be used to achieve a rapid drainage function along the extension direction of the first frame 100 and the second frame 101 of the roof unit 1, so as to avoid the formation of water accumulation on the surface of the roof unit 1, thereby preventing water from seeping into the gaps of the roof unit 1, accelerating the rapid aging of the sealant in the gaps of the roof unit 1 and causing water seepage, thereby affecting the user experience.

[0062] Specifically, if Figure 6As shown, taking the first drainage channel 105 formed on the second frame 101 as an example, the first drainage channel 105 is formed between the second connecting portion 101c and the roof glass 11, so that water spilled onto the roof glass 11 can flow into the first drainage channel 105. At the same time, the water level in the first drainage channel 105 is unlikely to exceed the end of the second connecting portion 101c, so that the water in the first drainage channel 105 is unlikely to penetrate into the connection between the first connecting portion 100c and the second connecting portion 101c.

[0063] Please also refer to Figure 6 and Figure 7 , Figure 7 This is a structural cross-sectional view of the roof unit 1 disclosed in the first aspect of the embodiment of the present application when the roof glass 11 is in an open posture. In some embodiments, the bracket 10 may further include a rotating portion 104. The first frame 100 or the second frame 101 is provided with a rotating portion 104. The roof glass 11 can be rotatably connected to the rotating portion 104. The roof glass 11 has a covering posture and an opening posture relative to the opening 102a of the light-transmitting space 102. When the roof glass 11 is in the covering posture, the roof glass 11 covers the opening 102a. When the roof glass 11 is in the open posture, the roof glass 11 rotates around the rotating portion 104 to expose the opening 102a. Thus, when the roof unit 1 is needed to achieve the functions of rain protection and heat preservation of the building, the roof glass 11 can be placed in a closed position to cover the opening 102a to prevent rainwater from entering the building through the opening 102a. The roof glass 11 is used to separate the interior space of the building from the exterior space at the opening 102a, slowing down the heat exchange rate between the interior and exterior of the building and achieving the building's heat preservation function. When the roof unit 1 is needed to achieve the ventilation and smoke exhaust function of the building, the roof glass 11 can be placed in an open position to expose the opening 102a, thereby enabling air exchange between the interior and exterior of the building through the opening 102a, achieving the functions of exhausting smoke from the interior of the building and ventilating the interior of the building.

[0064] Optionally, one of the rotating portion 104 and the roof glass 11 may include a rotating shaft, and the other may be provided with an axis hole, that is, the rotating portion 104 includes a rotating shaft and the roof glass 11 is provided with an axis hole, or the rotating portion 104 is provided with an axis hole and the roof glass 11 includes a rotating shaft, so that the rotating portion 104 and the roof glass 11 are rotationally connected through the axis hole, which is simple in structure and facilitates the effect of achieving the rotational connection between the two. Figure 6 and Figure 7 As shown, Figure 6 and Figure 7 It is shown that a rotating shaft is formed on one end of the rotating part 104 facing the roof glass 11, and an axis hole is formed on one side of the roof glass 11 for connecting to the second frame 101. The rotating part 104 and the roof glass 11 are rotatably connected through the axis hole.

[0065] It is understandable that since the roof glass 11 is located on the first top 100a of the first frame 100 and on one side of the second top 101a of the second frame 101, in order to facilitate opening of the roof glass 11 relative to the opening 102a, the rotating part 104 can be provided at the first top 100a or the second top 101a.

[0066] Optionally, the roof unit 1 may further include an annular protective frame 15, which is sleeved on the outer periphery of the roof glass 11 and covers the edge of the roof glass 11. The protective frame 15 can be rotatably connected to the rotating part 104, so that the edge of the roof glass 11 can be protected by the protective frame 15 to enhance the strength of the edge of the roof glass 11, so that the roof glass 11 is not easily damaged by external forces (such as pushing or pulling on the roof glass 11, impact between the roof glass 11 and the bearing surface of the bracket 10, or sliding friction between the roof glass 11 and the rotating part 104) during the process of switching between the covered posture and the open posture.

[0067] Optionally, the protective frame 15 can be fixedly connected to the roof glass 11 by at least one of structural adhesive and double-sided adhesive, so that the connection between the protective frame 15 and the roof glass 11 is more stable and firm, so that the protective frame 15 is not easy to separate from the roof glass 11, and the roof unit 1 is highly safe to use.

[0068] Optionally, the protective frame 15 can be an annular structure made of hollow profiles (such as hollow aluminum profiles or stainless steel profiles) and adapted to the edge shape of the roof glass 11, so that the protective frame 15 can have a certain strength to protect the roof glass 11, and at the same time can reduce the weight of the protective frame 15, thereby reducing the weight of the roof unit 1 and reducing the load on the building.

[0069] like Figures 6 to 8As shown, optionally, the roof unit 1 may further include a buffer seal 141, which may be provided on the protective frame 15 and / or the bracket 10, that is, the buffer seal 141 is provided on the protective frame 15, or on the bracket 10, or, the protective frame 15 and the bracket 10 are respectively provided with a buffer seal 141, and when the roof glass 11 is in a covering posture, the buffer seal 141 is clamped between the protective frame 15 and the bearing surfaces of the bracket 10, that is, between the protective frame 15 and the first bearing surface 100d and between the protective frame 15 and the second bearing surface 101d, so that the sealing and waterproof function between the protective frame 15 and the bracket 10 can be achieved through the buffer seal 141, so that when the roof glass 11 is in a covering posture, the roof glass 11 has a better sealing effect on the opening 102a. Furthermore, when the roof glass 11 switches from an open position to a covered position, that is, when the roof glass 11 switches from opening relative to the opening 102a to closing the opening 102a, the protective frame 15 will collide with the bearing surface of the bracket 10. By providing a buffer seal 141, the buffer seal 141 can be used to absorb the impact force, thereby reducing the impact force received by the bearing surfaces of the protective frame 15 and the bracket 10, reducing the possibility of deformation and damage of the protective frame 15 and the bracket 10 due to the impact force, extending the service life of the roof unit 1, and at the same time reducing the noise generated when the protective frame 15 collides with the bracket 10, thereby improving the user experience of the roof unit 1.

[0070] Optionally, the buffer seal 141 can be a sealing strip made of an elastic, waterproof and breathable material such as EPDM (Ethylene Propylene Diene Monomer) plastic or rubber, so that the buffer seal 141 can prevent water and air outside the roof unit 1 from entering the opening 102a through the gap between the protective frame 15 and the bracket 10 when it is clamped between the protective frame 15 and the bearing surface of the bracket 10, thereby achieving a waterproof sealing effect.

[0071] In some embodiments, the roof unit 1 may further include an electric window opener 16. One end of the electric window opener 16 is connected to the first frame 100 or the second frame 101, and the other end of the electric window opener 16 is rotatably connected to the protective frame 15. The electric window opener 16 is electrically connected to an external power source and is used to drive the roof glass 11 to switch between a closed position and an open position, thereby realizing the automatic opening and closing function of the roof glass 11. This simplifies the opening and closing control of the roof glass 11 and increases the convenience of use of the roof unit 1. Optionally, the electrical connection between the electric window opener 16 and the external power source can be partially routed along the bracket 10, that is, the electrical connection between the electric window opener 16 and the external power source can be partially routed along at least one of the first frame 100 and the second frame 101, thereby making the routing of the electrical connection neat and concise.

[0072] Optionally, the electric window opener 16 may be a screw-type electric window opener 16, a rack-type electric window opener 16, a push-rod-type electric window opener 16, or a chain-type electric window opener 16. Exemplarily, the electric window opener 16 is a screw-type electric window opener 16, so that the push-pull force of the electric window opener 16 is relatively large, and can be suitable for pushing and pulling larger roof glass 11.

[0073] Please also refer to Figure 6 、 Figure 7 and Figure 9 Specifically, the electric window opener 16 may include a fixed rod 160, a telescopic rod 161 and a motor 162, one end of the fixed rod 160 is rotatably connected to the bracket 10, the fixed rod 160 has a accommodating cavity 163, one end of the telescopic rod 161 is slidably connected to the accommodating cavity 163 along the extension direction of the fixed rod 160, the other end of the telescopic rod 161 is located at the other end of the fixed rod 160, and the other end of the telescopic rod 161 is rotatably connected to the protective frame 15, the motor 162 is at least partially disposed in the accommodating cavity 163 and is located at one end of the fixed rod 160, the motor 162 is electrically connected to an external power supply, the output end of the motor 162 is threadedly connected to one end of the telescopic rod 161, and the motor 162 is used to rotate The groove transmission drives one end of the telescopic rod 161 to slide along the extension direction of the fixed rod 160, so that the telescopic rod 161 can telescope relative to the fixed rod 160. When the telescopic rod 161 extends from the fixed rod 160, the other end of the telescopic rod 161 pushes the protective frame 15 to drive the roof glass 11 away from the opening 102a through the protective frame 15, so that the roof glass 11 is in an open position. When the telescopic rod 161 is retracted from the fixed rod 160, the other end of the telescopic rod 161 pulls the protective frame 15 to drive the roof glass 11 toward the opening 102a through the protective frame 15, so that the roof glass 11 moves to cover the opening 102a, and the roof glass 11 is in a covered position.

[0074] In some embodiments, the roof unit 1 may further include an electric lock (not shown in the figure), which is provided on the bracket 10 and electrically connected to the external power supply. The electric lock is used to automatically lock the connection to the protective frame 15 when the roof glass 11 is in the covering posture, so that the protective frame 15 is locked to the bracket 10, thereby providing a greater locking force for the glass roof to maintain the covering posture, so that the roof unit 1 can remain in the covering posture when subjected to greater external forces (such as wind force, vibration force). It is understandable that when the roof glass 11 needs to switch from the covering posture to the open posture, the electric lock can be automatically unlocked to loosen the protective frame 15 from the bracket 10. Optionally, the electrical connection between the electric lock and the external power supply can be partially routed along the bracket 10, so that the routing of the electrical connection is regular and concise.

[0075] Optionally, the electric lock can be an electric multi-point lock, such as an electric six-point lock, an electric four-point lock, an electric eight-point lock, etc., thereby increasing the number of locking points between the electric lock and the protective frame 15, and the electric lock applies a greater locking force on the protective frame 15 and a larger effective area. The locking force acts more evenly, and the locking connection between the roof glass 11 and the bracket 10 is more stable.

[0076] Please also refer to Figure 1 and Figure 10 In some embodiments, the bracket 10 may further include a third frame 103, which is connected between the first frame 100 and the second frame 101. The extension direction of the third frame 103 is perpendicular to the extension directions of the first frame 100 and the second frame 101, so that the relative position between the first frame 100 and the second frame 101 can be fixed by the third frame 103, so that the bracket 10 as a whole is formed into a stable shape structure to better provide stable support for the roof glass 11.

[0077] Optionally, the third frame 103 can be a long hollow rod-shaped structure made of hollow profiles (such as hollow aluminum profiles or stainless steel profiles), so that the third frame 103 can have a certain strength so that the bracket 10 can be used to support the roof glass 11, and at the same time can reduce the overall weight of the bracket 10, thereby reducing the weight of the roof unit 1 and reducing the load on the building.

[0078] Optionally, there may be multiple third frames 103, which are arranged at intervals along the extension direction of the first frame 100 and the second frame 101. By increasing the number of third frames 103, the fixing effect of the third frames 103 on the first frame 100 and the second frame 101 can be enhanced, thereby further strengthening the overall stability of the bracket 10.

[0079] like Figure 10 As shown, optionally, a third top of the third frame 103 is further formed with a third bearing surface 103a, and the third bearing surface 103a is located on the side of the roof glass 11 facing the opening 102a, and the third bearing surface 103a is connected to the roof glass 11. By supporting the roof glass 11 through the third bearing surface 103a, the connection area between the third frame 103 and the roof glass 11 can be increased, thereby enhancing the supporting stability of the third frame 103 on the roof glass 11, reducing the pressure at the connection between the third frame 103 and the roof glass 11, avoiding damage to the roof glass 11 due to excessive local force, and improving the safety of the roof unit 1.

[0080] As mentioned above, the components of the roof unit 1 can be filled or coated with silicone weather-resistant sealant 14a to fill and seal the gaps between the components of the roof unit 1. Therefore, in order to facilitate the sealing and waterproofing at the edge of the roof glass 11, the third bearing surface 103a of the third frame 103 can be set corresponding to the edge of the roof glass 11, and the third bearing surface 103a and the roof glass 11 can be filled with silicone weather-resistant sealant 14a.

[0081] It should be noted that the first frame 100, the second frame 101 and the third frame 103 may all be formed with a bearing surface, or some of the first frame 100, the second frame 101 and the third frame 103 may be formed with a bearing surface, for example, the first frame 100 is formed with a first bearing surface 100d and the second frame 101 is formed with a second bearing surface 101d, or the second frame 101 is formed with a second bearing surface 101d and the third frame 103 is formed with a third bearing surface 103a, or only the third frame 103 is formed with the third bearing surface 103a, or only the first frame 100 is formed with the first bearing surface 100d, etc. It can be understood that when the first frame 100, the second frame 101 and the third frame 103 are all formed with bearing surfaces, that is, the first frame 100 is formed with the first bearing surface 100d, the second frame 101 is formed with the second bearing surface 101d, and the third frame 103 is formed with the third bearing surface 103a, the connection area between the bracket 10 and the roof glass 11 is the largest, the supporting effect of the bracket 10 on the roof glass 11 is the most stable, and the pressure between the bracket 10 and the roof glass 11 is the smallest, the local supporting force on the roof glass 11 is the smallest, and the safety of the roof unit 1 is the highest.

[0082] See also Figure 11 As described above, when the roof glass 11 is rotatably connected to the bracket 10, the roof unit 1 may include a buffer seal 141 disposed between the bracket 10 and the roof glass 11. Optionally, when the roof unit 1 includes a third frame 103, the buffer seal 141 may also be disposed between the protective frame 15 and the third bearing surface 103a. The specific arrangement of the buffer seal 141 between the protective frame 15 and the third bearing surface 103a and the effects of its use can be referred to above and will not be repeated here.

[0083] Furthermore, at this time, the roof unit 1 may also include an electric window opener 16 and an electric lock. The electrical connection between the electric window opener 16 and the electric lock and the external power supply can be partially routed along the bracket 10. Therefore, when the roof unit 1 also includes a third frame 103, the electrical connection between the electric window opener 16 and the electric lock and the external power supply can be partially routed along at least one of the first frame 100, the second frame 101 and the third frame 103, thereby making the routing of the electrical connection regular and concise.

[0084] Please also refer to Figure 2 、 Figure 3 and Figure 12 As described above, the roof unit 1 includes a shielding member 12 and a light-emitting member 13. The shielding member 12 is connected to the first top 100a of the first frame 100 and is located on the side of the first frame 100 away from the light-transmitting space 102. The shielding member 12 has a first surface 12a facing the first bottom 100b of the first frame 100, and the first surface 12a is at least partially formed as a reflective surface. The light-emitting member 13 is provided at the first bottom 100b of the first frame 100 and is located on the side of the first frame 100 away from the light-transmitting space 102, and the light-emitting end of the light-emitting member 13 faces the first surface 12a.

[0085] Optionally, the shielding member 12 may extend along the extension direction of the first frame 100 , so that the shielding member 12 has a larger shielding area and a better shielding effect.

[0086] In some embodiments, the first surface 12a can be an inclined surface, gradually sloping from the side connected to the first frame 100 to the side facing away from the first frame 100. This allows the thickness of the shielding member 12 to gradually decrease, thereby using less material and lowering manufacturing costs. Furthermore, the volume and weight of the shielding member 12 gradually decrease from the side connected to the first frame 100 to the side facing away from the first frame 100. This provides a more stable support for the shielding member 12 by the first frame 100, making it less likely for the shielding member 12 to be separated from the first frame 100 due to external forces (such as wind), thereby enhancing the structural stability of the roof unit 1 and improving safety. Furthermore, by forming the first surface 12a as an inclined surface, the optical path of light reflected by the first surface 12a can be adjusted by adjusting the inclination of the first surface 12a. This allows light emitted by the light-emitting element 13 to be reflected by the first surface 12a and illuminate the other roof glass panels 11 included in the roof unit 1, creating a similar wall-washing effect. For example, when the roof unit 1 is used in a roof system, the roof system may include multiple roof units 1, which are arranged adjacent to each other. For example, two adjacent roof units 1 are a first roof unit 1a and a second roof unit 1b. The first surface 12a of the first roof unit 1a reflects light emitted by the light-emitting element 13 to the second roof unit 1b, thereby creating a lighting effect similar to a wall wash on the second roof unit 1b.

[0087] Furthermore, when the roof glass 11 is rotatably connected to the bracket 10, forming the first surface 12a as an inclined surface can also reduce the space occupied by the shielding member 12, thereby avoiding the roof glass 11 and making the rotation angle of the roof glass 11 relative to the bracket 10 larger, so that when the roof glass 11 is in the open position, the smoke exhaust and ventilation efficiency of the roof unit 1 is higher.

[0088] Optionally, the shielding member 12 can be a long hollow profile made of a metal material such as aluminum, iron, or steel, or a structure formed by bending a thin plate. This allows the shielding member 12 to have good toughness and deformation resistance while reducing its weight, making it easier to securely connect the shielding member 12 to the first frame 100. This can also reduce the overall weight of the roof unit 1, making the roof unit 1 more lightweight. Furthermore, by making the shielding member 12 from metal, the high reflectivity of metal can be utilized to form the first surface 12a into a light-reflecting surface. It will be appreciated that in other embodiments, the first surface 12a can also be formed into a light-reflecting surface by providing a reflective film layer, such as a metal film layer, a micro-prismatic reflective film, or a glass bead reflective film, on the first surface 12a of the shielding member 12.

[0089] like Figure 12 As shown, in some embodiments, a water leakage port 120 may be provided on one side of the shielding member 12 close to the first frame 100. The water leakage port 120 is used to allow water on the surface or inside of the roof unit 1 to flow to the outside of the roof unit 1 in a timely and rapid manner, thereby preventing water from accumulating in the roof unit 1, and preventing water from penetrating into the gaps between the components of the roof unit 1 and contacting the silicone weather-resistant sealant 14a in the gaps, causing the silicone weather-resistant sealant 14a to age and accelerate the decline in sealing performance, thereby avoiding water leakage in the roof unit 1 and extending the service life of the roof unit 1.

[0090] Optionally, the leakage port 120 can be filled with dust-proof and water-permeable materials, such as sponge, dust-proof net, dust-proof cloth, etc., so as to prevent dust from passing through the leakage port 120 without affecting the leakage performance of the leakage port 120, thereby preventing dust from entering the interior of the shielding member 12 or circulating inside the shielding member 12.

[0091] Specifically, when the shielding member 12 is a long hollow profile, the shielding member 12 includes a hollow portion 121, and the leakage port 120 may include a first leakage port 120a. The first leakage port 120a is provided on the side of the first bottom 100b of the shielding member 12 facing the first frame 100. The hollow portion 121 is connected to the external space on the side of the shielding member 12 facing the first bottom 100b through the first leakage port 120a. The first leakage port 120a is used to drain water that penetrates or flows into the hollow portion 121 to the outside of the hollow portion 121 to avoid water accumulation in the hollow portion 121, which increases the weight of the shielding member 12 and affects the connection stability between the shielding member 12 and the first frame 100. The water will not deteriorate or breed mosquitoes due to long-term accumulation, thereby affecting the sanitary environment of the building.

[0092] It should be noted that, as mentioned above, the first bottom 100b of the first frame 100 may be provided with a first connecting portion 100c, and the second top 101a of the second frame 101 may be provided with a second connecting portion 101c, the first connecting portion 100c is used to cooperate with the second connecting portion 101c included in other roof units 1 for connection, and the second connecting portion 101c is used to cooperate with the first connecting portion 100c included in other roof units 1 for connection, and the second frame 101 may be formed with a first drainage channel 105, the first drainage channel 105 is located between the second connecting portion 101c and the roof glass 11, and since the shielding member 12 is provided at the first top 100a of the first frame 100, as shown Figure 12 As shown, Figure 12 The figure shows the partial structure of the first connecting portion 100c and the second connecting portion 101c of two adjacent roof units 1. Therefore, it is easy to understand that the shielding member 12 can be located above the first drainage channel 105 of the adjacent roof unit 1. Therefore, in order to more effectively drain the accumulated water, the first drainage opening 120a should be positioned toward the first drainage channel 105 of the adjacent roof unit 1, so that the accumulated water discharged through the first drainage opening 120a can fall into the first drainage channel 105 instead of falling onto the roof glass 11 of the adjacent roof unit 1.

[0093] Optionally, there may be multiple hollow portions 121, and the water leakage port 120 may further include a second water leakage port 120b, which is connected between two adjacent hollow portions 121. The second water leakage port 120b is used to allow water in the hollow portion 121 to circulate between the multiple hollow portions 121, so that water that penetrates into one of the hollow portions 121 can flow to other hollow portions 121 through the second water leakage port 120b until the water flows into the hollow portion 121 provided with the first water leakage port 120a, and flows to the outside of the roof unit 1 through the first water leakage port 120a.

[0094] Optionally, the drain port 120 may further include a third drain port (not shown). The third drain port is provided on the side of the shielding member 12 facing the first top portion 100a of the first frame 100. The hollow portion 121 is connected to the external space on the side of the shielding member 12 facing the first top portion 100a through the third drain port. The third drain port is used to allow water that spills onto the roof glass 11 or shielding member 12 to flow toward the hollow portion 121, thereby preventing water from accumulating on the surface of the roof unit 1. This reduces the load on the roof glass 11 or shielding member 12 and the possibility of water penetrating the joints between the various components of the roof unit 1. This can prevent rapid aging of the silicone weatherproof sealant 14a filling the joints between the various components, thereby extending the service life of the roof unit 1. Therefore, when water spills onto the roof glass 11 or shielding member 12, the water can be quickly discharged to the exterior of the roof unit 1 through the third drain port, the second drain port 120b, and the first drain port 120a, in sequence.

[0095] Please also refer to Figure 3 、 Figure 5 and Figure 12 In some embodiments, the light-emitting component 13 may be located on the side of the shielding component 12 connected to the first frame 100, so that on the one hand, the shielding component 12 can cover a larger range of the light-emitting component 13 and have a better shielding effect. On the other hand, a larger portion of the light emitted by the light-emitting component 13 can be directed toward the first surface 12a of the shielding component 12, so that more light can be reflected by the first surface 12a to the roof glass 11, and the lighting effect of the light-emitting component 13 is brighter.

[0096] Optionally, the light-emitting element 13 can be an LED (light-emitting diode) light strip or light beads, thereby providing excellent lighting effects and low energy consumption. For example, if the light-emitting element 13 is an LED light strip, the light-emitting element 13 can emit a uniform strip of light and can undergo certain deformations, making it suitable for producing a variety of strip light shapes or for application to various surfaces. Furthermore, because the light beads and circuitry of the LED light strip are encased in flexible plastic, the light-emitting element 13 has good waterproof and insulating properties, making it suitable for outdoor environments.

[0097] In some embodiments, the first bottom 100b of the first frame 100 may be provided with a lamp groove 130 opened toward the first surface 12a, and the light-emitting component 13 is installed in the lamp groove 130. By providing the lamp groove 130, an installation space can be provided for the light-emitting component 13, and part of the outer periphery of the light-emitting component 13 can be shielded to protect the light-emitting component 13. At the same time, a fixed reference is provided for the light-emitting component 13 to fix the shape of the light-emitting component 13. The light emitted by the light-emitting component 13 can also be reflected by the groove wall of the lamp groove 130, so as to reflect part of the light directed toward the groove wall of the lamp groove 130 toward the first surface 12a, thereby further enhancing the lighting effect of the roof unit 1.

[0098] It can be understood that the lamp trough 130 can be a long strip lamp trough, and the extension direction of the lamp trough 130 is the same as the extension direction of the shielding member 12, so that the light-emitting member 13 installed in the lamp trough 130 can extend along the extension direction of the shielding member 12 to ensure that the light-emitting member 13 always emits light toward the first surface 12a of the shielding member 12, and ensure that the shielding member 12 can always provide shielding effect for the light-emitting member 13.

[0099] Next, the specific structure of the roof glass 11 will be described in detail with reference to the accompanying drawings.

[0100] Please also refer to Figures 11 to 13In some embodiments, at least a portion of the surface of the roofing glass 11 facing the opening 102a may be covered with a reflective layer 110. The reflective layer 110 is used to reflect light toward the exterior of the roofing unit 1, allowing users to more clearly observe the luminous effect of the roofing unit 1 from outside the roof. Optionally, the reflective layer 110 may be formed into an image or gradient pattern, so that light reflected by the reflective layer 110 forms a bright image or gradient pattern. Furthermore, when the reflective layer 110 is used to form an image or gradient pattern, the reflective layer 110 may be a discontinuous layer, that is, the reflective layer 110 only covers a portion of the surface of the roofing glass 11 facing the opening 102a. This allows the portion of the roofing glass 11 not covered by the reflective layer 110 to have better light transmission, ensuring that the roofing unit 1 can achieve a certain lighting function within the building.

[0101] Optionally, the reflective layer 110 can also reflect light of one or more colors, so that the light emitted by the light emitting element 13 is reflected by the reflective layer 110, and the user can observe one or more colors. It is understood that the reflective layer 110 can be formed into an image or a gradient pattern while reflecting light of one or more colors. Therefore, the light emitted by the light emitting element 13 is reflected by the reflective layer 110, which can make the roof glass 11 present a bright pattern of monochrome or color, achieving a wider variety of lighting effects.

[0102] Optionally, the reflective layer 110 may be located on the side of the roof glass 11 facing the interior of the building, thereby preventing the reflective layer 110 from being hit or scratched by wind, rain, sand, soil or dust, thereby reducing the possibility of the luminous layer detaching from the roof glass 11 and effectively extending the service life of the luminous layer.

[0103] In some embodiments, the reflective layer 110 can be a colored glaze layer, a colored glass film layer, or a metal film layer. Thus, the reflective layer 110 can be applied to the surface of the roof glass 11 and can reflect light of one or more colors. For example, the reflective layer 110 can be a colored glaze layer, making it wear-resistant, acid- and alkali-resistant, and having a long service life. It can also be easily formed into patterns of various colors and shapes, thus providing a wide range of applications.

[0104] like Figure 13As shown, optionally, the roof glass 11 may also be provided with a low-emissivity layer 111, which is covered on the surface of the roof glass 11 and the reflective layer 110. That is, when part of the surface of the roof glass 11 is covered with the reflective layer 110, the low-emissivity layer 111 is covered on the reflective layer 110, and is covered on the surface of the remaining part of the roof glass 11 not covered with the reflective layer 110, so that the low-emissivity layer 111 more completely covers the surface of the roof glass 11. The low-emissivity layer 111 is used to reduce the heat transfer emissivity of the roof glass 11, so as to reduce the heat exchange efficiency between the interior space and the exterior space of the building, so as to reduce the speed of heat radiation from the outside of the building to the inside of the building when the temperature of the exterior space of the building is higher than the temperature of the interior space of the building, and reduce the speed of heat radiation from the inside of the building to the outside of the building when the temperature of the exterior space of the building is lower than the temperature of the interior space of the building, so as to improve the thermal insulation effect of the building and reduce the energy consumption of air conditioning or heating in the building.

[0105] It should be noted that, as described above, the light emitted by the light-emitting element 13 is reflected by the first surface 12a to the surface directed toward the roof glass 11. When the surface of one side of the roof glass 11 is sequentially covered with a reflective layer 110 and a low-emissivity layer 111, the reflective layer 110 should be located on the side of the low-emissivity layer 111 facing the outside of the building, so that the light directed toward the roof glass 11 can be directly directed toward the reflective layer 110, that is, the light does not need to pass through the low-emissivity layer 111 and then toward the reflective layer 110, so that more light is directed toward the reflective layer 110, thereby enabling the reflective layer 110 to reflect more light, and thus achieving a better lighting effect for the roof unit 1.

[0106] Exemplarily, the low-emissivity layer 111 may be a Low-e (Low Emissivity) film layer including a metallic silver film layer, thereby utilizing the good radiation protection properties of metallic silver to achieve the function of the low-emissivity layer 111 of reducing the heat exchange efficiency between the two opposite sides of the low-emissivity layer 111. At the same time, since only a small amount of metallic silver is required to achieve the effect of reducing the heat exchange efficiency, the metallic silver film layer may be relatively thin, so that the light transmittance of the low-emissivity layer 111 is better, thereby ensuring the light transmittance of the roof glass 11 and the lighting effect of the roof glass 11.

[0107] like Figure 11 and Figure 13As shown, in some embodiments, the roof glass 11 may further include a first glass 112, a second glass 113 and a sealant 114. The first glass 112 and the second glass 113 are spaced apart to form an air layer 115 therebetween, and the first glass 112 is located above the second glass 113. The sealant 114 is arranged at the edge of the first glass 112 and the second glass 113, and the sealant 114 is located between the first glass 112 and the second glass 113 to separate the air layer 115 from the external space of the roof glass 11, thereby preventing water, dust and other debris from entering the air layer 115, and blocking convection between the air in the air layer 115 and the air outside the roof glass 11, thereby making use of the property of air as a poor conductor of heat to further improve the thermal insulation effect of the roof glass 11.

[0108] Optionally, the air layer 115 may be filled with dry inert gas to prevent substances from chemically reacting between the first glass 112 and the second glass 113, which may cause changes in the performance of the roof glass 11. For example, mold may form between the first glass 112 and the second glass 113, resulting in a decrease in the light transmittance and reflective properties of the roof glass 11, making it look dirty.

[0109] Furthermore, when the roof unit 1 is used on a building, the second glass 113 is located on the side of the first glass 112 facing the interior of the building, the reflective layer 110 can be provided on the surface of the first glass 112 facing the second glass 113, and the low-emissivity layer 111 is provided on the surface of the first glass 112 and the reflective layer 110 facing the second glass 113, that is, the surface of the low-emissivity layer 111 is arranged towards the air layer 115 to prevent the low-emissivity layer 111 from contacting the external air of the roof glass 11, thereby preventing the low-emissivity layer 111 from contacting water vapor, sulfides or oxides through the air and reacting chemically, causing the low-emissivity layer 111 to lose its radiation protection performance, and causing the low-emissivity layer 111 to become black, discolored, and gradually develop a large number of mold spots, thereby achieving the function of extending the service life of the low-emissivity layer 111.

[0110] In some embodiments, the first glass 112 and / or the second glass 113 may be laminated glass. That is, the first glass 112 is laminated glass, or the second glass 113 is laminated glass, or both the first glass 112 and the second glass 113 are laminated glass. Laminated glass has high strength and can withstand significant vibrations and impacts, such as impacts from stones carried by air currents. Thus, the roof glass 11 can protect the interior of the building and is not prone to shattering, resulting in a long service life. Even if the laminated glass shatters, the broken glass fragments and sharp glass shards remain attached to the interlayer film of the laminated glass. This means that the glass fragments will not disperse and will not fall into the building, preventing the fragments from striking and injuring people inside. The roof glass 11 is highly safe to use.

[0111] like Figure 11 and Figure 13 As shown, taking the second glass 113 as a laminated glass as an example, as mentioned above, the second glass 113 is located on the side of the first glass 112 facing the interior of the building. Therefore, setting the second glass 113 as a laminated glass can prevent glass fragments from falling when the second glass 113 is broken, and can also prevent glass fragments generated by the first glass 112 from falling into the interior of the building when the first glass 112 is broken, thereby making the roof unit 1 safer to use.

[0112] In some embodiments, the roof glass 11 may be fixedly connected to the bracket 10 , or the roof glass 11 may be rotatably connected to the bracket 10 .

[0113] like Figure 3 、 Figure 4 and Figure 10 As shown, in an optional embodiment, the roof glass 11 is fixedly connected to the bracket 10, so that the relative position between the roof glass 11 and the bracket 10 is fixed, and the connection structure between the roof glass 11 and the bracket 10 is simple.

[0114] Optionally, the roof glass 11 can be fixedly connected to the bracket 10 using at least one of structural adhesive and double-sided tape, thereby making the connection between the roof glass 11 and the bracket 10 more stable and secure, thereby preventing the roof glass 11 from easily separating from the bracket 10 and improving the safety of the roof unit 1. Specifically, the edges of the roof unit 1 are fixedly connected to the first frame 100, the second frame 101, and the third frame 103 using structural adhesive and double-sided tape, thereby ensuring that the roof unit 1 is balanced and firmly connected to the bracket 10.

[0115] It is easy to understand that in order to enhance the sealing performance of the roof unit 1 , a silicone weatherproof sealant 14 a may be filled between the roof glass 11 and the bracket 10 .

[0116] like Figure 6 、 Figure 7 and Figure 11 As shown, in another optional embodiment, the roof glass 11 can be rotatably connected to the bracket 10, so that the roof glass 11 can have a covering posture and an open posture relative to the opening 102a. When the roof glass 11 is in the covering posture, the roof glass 11 can cover the opening 102a to prevent rainwater from entering the interior of the building through the opening 102a, and the roof glass 11 separates the interior space and the exterior space of the building at the opening 102a, slowing down the heat exchange rate between the inside and outside of the building, and realizing the insulation function of the building. When the roof glass 11 is in the open posture, the opening 102a is exposed, so that air exchange between the inside and outside of the building can be realized through the opening 102a, realizing the function of exhausting the smoke inside the building and ventilating the interior of the building.

[0117] As mentioned above, at this time, the bracket 10 may also include a rotating part 104, the first frame 100 or the second frame 101 is provided with a rotating part 104, and the roof unit 1 may also include a protective frame 15, the protective frame 15 is fixedly sleeved on the outer periphery of the roof glass 11, and the protective frame 15 can be rotatably connected to the rotating part 104, so that the roof glass 11 can be rotatably connected to the bracket 10.

[0118] In some embodiments, the roof glass 11 may be one or more pieces. When the roof glass 11 is multiple pieces, the multiple pieces of roof glass 11 are arranged along the extension direction of the first frame 100, so that roof glass 11 with a smaller area can be used to form a roof unit 1 with a larger area. While increasing the area of ​​the roof unit 1, there is no need to use large-area glass with high manufacturing difficulty, high production cost and lower strength. The manufacturing cost of the roof unit 1 can be reduced, and the strength of the roof unit 1 can be increased, so that the roof unit 1 can be more suitable for withstanding greater external forces and has high safety in use. Figure 14 As shown, Figure 14 The figure shows the structure of the roof unit 1 when there are four roof glass panels 11 .

[0119] In some embodiments, the plurality of roofing glasses 11 may be fixedly connected or movably connected. Figure 14 、 Figure 15 In an optional embodiment, multiple roofing glass panels 11 can be fixedly connected using at least one of double-sided tape or structural adhesive, thereby forming a single, integrated structure. Furthermore, silicone weatherproof sealant 14a can be placed between adjacent panels of roofing glass 11 to enhance the waterproof and sealing properties of the roofing unit 1.

[0120] like Figure 14 、 Figure 16As shown, in another optional embodiment, multiple roofing glasses 11 are movable, so that each roofing glass 11 is independent of each other. The arrangement of each roofing glass 11 is more flexible, and the roofing unit 1 can achieve more different designs to meet more different usage requirements.

[0121] As mentioned above, the roof glass 11 can be fixedly connected to the bracket 10 or rotatably connected to the bracket 10. Optionally, at this time, multiple pieces of roof glass 11 can be fixedly connected to the bracket 10, or can be rotatably connected to the bracket 10, or, among the multiple pieces of roof glass 11, some roof glass 11 are fixedly connected to the bracket 10, and the remaining roof glass 11 can be rotatably connected to the bracket 10, so that the maximum ventilation and smoke exhaust efficiency achievable by the roof unit 1 can be freely adjusted to make the roof unit 1 meet the design and usage requirements.

[0122] Taking the example of multiple roofing glasses 11 that can be rotatably connected to the bracket 10, since each roofing glass 11 is independent of each other, the posture of each roofing glass 11 can be flexibly adjusted to freely adjust the actual ventilation and smoke exhaust efficiency of the roofing unit 1, so that the roofing unit 1 is suitable for use in situations where the actual ventilation and smoke exhaust efficiency requirements may vary within a certain range, and the roofing unit 1 has a wide range of applications.

[0123] Optionally, at this time, a protective frame 15 may be provided on the periphery of each roof glass 11, and a sealing connector 142 may be provided on the side of the protective frame 15 facing the adjacent protective frame 15. The sealing connector 142 extends along the edge of the roof glass 11. When the two adjacent roof glasses 11 are in a covering posture, the sealing connector 142 is used to be clamped between the two protective frames 15 on the periphery of the two roof glasses 11, so as to seal the gap between the two adjacent protective frames 15 through the sealing connector 142, thereby making the sealing and waterproof effect of the roof unit 1 better.

[0124] Optionally, the sealing connector 142 can be a sealing strip made of an elastic, waterproof and breathable material such as EPDM (Ethylene Propylene Diene Monomer) plastic or rubber, so that the sealing connector 142 can prevent water and air outside the roof unit 1 from entering the opening 102a through the gap between the two adjacent protective frames 15 when clamped between the two adjacent protective frames 15, thereby achieving a waterproof sealing effect.

[0125] Optionally, two adjacent protective frames 15 may be respectively provided with two opposing sealing connectors 142. When the two adjacent roofing glasses 11 are in a covering posture, the two opposing sealing connectors 142 are pressed and connected. Since hard materials have poor elasticity, when the hard materials are pressed and connected to other structures, the unevenness on the surface of the hard materials is difficult to fill. Therefore, compared with the elastic sealing connector 142 being pressed and connected to the hard protective frame 15, the sealing performance of the two elastic sealing connectors 142 being pressed and connected is better. Therefore, the use of two elastic sealing connectors 142 being pressed and connected can further improve the waterproof sealing performance of the roof unit 1.

[0126] Optionally, there may be multiple sealing connectors 142 provided on one side of the protective frame 15, and multiple sealing connectors 142 are arranged at intervals along the direction from the opening 102a toward the protective frame 15. By increasing the number of sealing connectors 142, the waterproof sealing effect between two adjacent protective frames 15 can be further enhanced, thereby further enhancing the waterproof sealing performance of the roof unit 1.

[0127] By using the roof glass 11 to close the opening 102a, the roof unit 1 achieves the function of separating the interior of the building from the exterior, and also achieves the daytime lighting function of the interior of the building. At the same time, by providing the shielding member 12, the light-emitting member 13 can be shielded, making it difficult for users to observe the light-emitting member 13 from the outside of the building, thereby making the roof structure of the building simpler and preventing wind and rain from directly affecting the light-emitting member 13, thereby extending the service life of the light-emitting member 13. By the light-emitting member 13 emitting light toward the first surface 12a of the shielding member 12, the light emitted by the light-emitting member 13 can be reflected by the first surface 12a and then evenly illuminated by the roof glass 11, achieving a uniform lighting effect. At the same time, in conjunction with the light-transmitting function of the roof glass 11, it is possible to achieve a certain degree of internal lighting of the building while achieving external lighting of the roof. At the same time, by covering the roof glass 11 with a reflective layer 110, the reflectivity of the roof glass 11 to the light irradiated on the roof glass 11 can be further improved, thereby improving the external lighting effect of the roof glass 11. By providing a low-emissivity layer 111 on the roof glass 11, the heat exchange efficiency between the two opposite sides of the roof glass 11 can be reduced, thereby improving the thermal insulation effect of the roof unit 1.

[0128] Furthermore, by forming a first drainage channel 105 on the bracket 10, water spilled onto the roof unit 1 can be quickly drained, thereby preventing water from accumulating on the roof unit 1 and penetrating into the gaps between the components of the roof unit 1, accelerating the aging of the sealant in the gaps of the roof unit 1, and destroying the sealing performance of the roof unit 1.

[0129] Furthermore, by making the roof glass 11 rotatably connected to the rotating part 104, the roof glass 11 can have a covering posture and an open posture relative to the opening 102a, so that the roof glass 11 can achieve the functions of space separation and heat preservation when in the covering posture, and achieve the functions of ventilation and smoke exhaust when in the open posture.

[0130] It can be seen that the roof unit 1 provided in the embodiment of the present invention can realize a variety of different functions, such as space partition function, daytime natural lighting function, uniform lighting function on the roof surface, building interior lighting function, ventilation and smoke exhaust function, rapid drainage function, thermal insulation function and simple roof effect. By integrating the various functions of the building into the roof unit 1, the overall design and construction of the building can be simplified, and the difficulty and cost of the overall design and construction of the building can be reduced.

[0131] Please also refer to Figures 17 to 19 , Figure 17 is a structural diagram of the roofing system disclosed in the second aspect of the embodiment of this application, Figure 18 yes Figure 17 A cross-sectional view along the GG direction, Figure 19 yes Figure 18 As shown in the enlarged schematic diagram at I in FIG, a second aspect of an embodiment of the present application discloses a roof system 2. The roof system 2 is applied to a building. The building includes a main structure. The roof system 2 includes a roof frame 20 and a plurality of roof units 1 as described in the first aspect above. The roof frame 20 is disposed on the main structure, and the plurality of roof units 1 are disposed on the roof frame 20. The provision of the roof frame 20 can provide support for the roof units 1 and a reference for installation and connection of the roof units 1, so that the plurality of roof units 1 can be connected to form a roof. Furthermore, by forming a roof using roof units 1 having functions such as space partitioning, daylighting, lighting, ventilation and smoke exhaust, thermal insulation, and earthquake resistance and intrusion prevention, the roof system 2 can integrate multiple functions, thus having a wide range of applications and high safety in use. Moreover, since the roof system 2 consists of the roof frame 20 and the finished roof units 1, the design difficulty of the roof system 2 is low, the construction process is simple, and the design and construction costs are low.

[0132] Optionally, the roof frame 20 may be a steel structure with greater strength, such as a mouth-shaped steel or an I-shaped steel, so that the roof frame 20 can bear a greater load, thereby making the overall structure of the roof system 2 more stable and the roof system 2 safer to use.

[0133] In some embodiments, the roof frame 20 can be arranged to fit the roof shape of the building, that is, when the roof of the building is formed into a plane, the roof frame 20 can be arranged to fit the plane, and when the roof of the building is formed into a curved surface, the roof frame 20 can be arranged to fit the curved surface, so that the roof shape of the building can be constructed through the roof frame 20, so that the roof unit 1 can form the shape of the roof when it is installed on the roof frame 20.

[0134] Optionally, the roof frame 20 may include a plurality of longitudinal frames 200 and transverse frames 201 arranged at intervals, with the two ends of the transverse frame 201 respectively connected to two adjacent longitudinal frames 200, and the transverse frame 201 is perpendicular to the longitudinal frame 200, so that multiple roof frames 20 can be connected to form an integral structure. The structure is regular, simple and stable, can carry a large load and has good tensile and compressive resistance. It can be used to carry multiple roof units 1, and when subjected to certain external forces (such as the action of wind in windy weather, the impact of rain in rainy weather, or vibration during an earthquake), it can maintain the roof system 2 as a whole.

[0135] Optionally, multiple roof units 1 are arranged longitudinally along the extension direction of the longitudinal frame 200 and transversely along the extension direction of the transverse frame 201, so that the arrangement direction of the roof unit 1 is the same as the extension direction of the roof unit 1. This can simplify the arrangement pattern of the roof unit 1, make the structure of the roof system 2 easier to design, and make it easier for installers to find the installation reference of the roof unit 1 according to the roof frame 20, thereby simplifying the installation process.

[0136] Furthermore, along the longitudinal arrangement direction of the multiple roof units 1, the two adjacent roof units 1 are respectively the first roof unit 1a and the second roof unit 1b, and the roof glass 11 of the second roof unit 1b extends to below the first surface 12a of the shielding member 12 of the first roof unit 1a, so that the first surface 12a of the shielding member 12 of the first roof unit 1a reflects the light emitted by the light-emitting member 13 of the first roof unit 1a to the roof glass 11 of the second roof unit 1b, so as to illuminate the roof glass 11 of the second roof unit 1b evenly and over a large area, thereby forming a wall washing lighting effect on the surface of the roof glass 11 of the second roof unit 1b.

[0137] like Figure 12 and Figure 19As shown, as described in the first aspect above, the roof unit 1 has a first connecting portion 100c and a second connecting portion 101c for connecting with adjacent roof units 1. Specifically, along the longitudinal arrangement direction of multiple roofing units 1, the first connection part 100c of the first roofing unit 1a is connected to the second connection part 101c of the second roofing unit 1b, and the first connection part 100c of the first roofing unit 1a has a recess, and one end of the second connection part 101c of the second roofing unit 1b is formed as a protrusion, which extends into the recess, and a damping seal 140 is provided on the protrusion. The end of the damping seal 140 facing away from the protrusion is in interference and obliquely abutted against the surface of the first connection part 100c facing the recess. The damping seal 140 is used to generate resistance when there is a tendency for phase separation between the first connection part 100c and the second connection part 101c to prevent the first connection part 100c from separating from the second connection part 101c, thereby improving the stability of the connection between the two adjacent roofing units 1, and at the same time, the gap between the first connection part 100c and the second connection part 101c is partitioned to achieve a waterproof sealing effect. It is understandable that in other embodiments, the damping seal 140 may also be disposed in the recess, that is, the damping seal 140 may be disposed on the first connecting portion 100c, and the end of the damping seal 140 facing the protrusion may interfere obliquely with the surface of the protrusion.

[0138] Optionally, the damping seal 140 may be made of rubber, such as EPDM (Ethylene Propylene Diene Monomer) or nitrile rubber, which is an elastic material that is impermeable and breathable. In this way, the damping seal 140 can be interference-mounted between the first connecting part 100c and the second connecting part 101c, thereby preventing water and air from flowing in the gap between the first connecting part 100c and the second connecting part 101c, thereby achieving a waterproof sealing effect.

[0139] Optionally, there may be multiple damping seals 140, and the multiple damping seals 140 are arranged at intervals. By increasing the number of damping seals 140, the connection area between the damping seal 140 and the first connection part 100c and the second connection part 101c can be increased, thereby improving the damping effect of the damping seal 140 and improving the connection stability between the first connection part 100c and the second connection part 101c.

[0140] In some embodiments, two adjacent brackets 10 are connected, and the space between the two adjacent brackets 10 can be filled with insulation material 23, such as insulation cotton, rigid foam polyurethane or glass wool, so that the connection between the two adjacent roof units 1 also has insulation function, thereby further improving the insulation performance of the roof system 2.

[0141] In some embodiments, the roof system 2 may further include a plurality of first connecting seats 202, the first connecting seat 202 including a first fixing portion 202a and a second fixing portion 202b spaced opposite to each other, the first fixing portion 202a and the second fixing portion 202b are both fixedly disposed on the transverse frame 201, a first fixing space 202c is formed between the first fixing portion 202a and the second fixing portion 202b, the first connecting portion 100c of the first roof unit 1a is connected to the second connecting portion 101c of the second roof unit 1b, the first bottom 100b of the first roof unit 1a and the second bottom 101b of the second roof unit 1b are both extended into the corresponding first fixing portion 202c. In a fixed space 202c, the first bottom 100b of the first roof unit 1a is connected to the first fixing portion 202a, and the second bottom 101b of the second roof unit 1b is connected to the second fixing portion 202b. By arranging a first connecting seat 202 on the transverse frame 201 to connect to the roof unit 1, the first connecting seat 202 can be adapted to be connected to the roof unit 1 by adjusting the shape of the first connecting seat 202. That is, there is no need to adjust the shape of the transverse frame 201. Only the shape of the first connecting seat 202 needs to be adjusted to make the transverse frame 201 adapted to be connected to different roof units 1. The roof system 2 has a flexible structure and a wide range of applications. Exemplarily, the first fixing portion 202a is a steel plate adapted to the first bottom portion 100b of the first roof unit 1a, and the second fixing portion 202b is a steel plate adapted to the second bottom portion 101b of the second roof unit 1b. The first fixing portion 202a and the second fixing portion 202b are welded to the transverse frame 201 on one side facing away from the roof unit 1. A rib 202d can be fixedly connected between the first fixing portion 202a and the second fixing portion 202b. The rib 202d is used to reinforce the structure of the first fixing portion 202a and the second fixing portion 202b, so that the first connecting seat 202 has high strength and is suitable for bearing the roof unit 1. The overall structure of the roof system 2 is firm and stable, and is highly safe to use.

[0142] Optionally, along the longitudinal arrangement direction of the multiple roof units 1, the two adjacent roof glass panels 11 included in two adjacent roof units 1 can be fixedly connected to each bracket 10, or can be rotatably connected to each bracket 10, or, among the two adjacent roof glass panels 11, one roof glass panel 11 is fixedly connected to the corresponding bracket 10, and the remaining roof glass panel 11 can be rotatably connected to the corresponding bracket 10.

[0143] In an optional example, Figure 19 and Figure 20 As shown, Figure 19 and Figure 20 It is shown that the roof glass 11 included in the first roof unit 1a is fixedly connected to the first frame 100 included in the first roof unit 1a, and the roof glass 11 included in the second roof unit 1b is fixedly connected to the second frame 101 included in the second roof unit 1b.

[0144] In another alternative example, Figure 21 and Figure 22 As shown, Figure 21 and Figure 22 It is shown that the roof glass 11 included in the first roof unit 1a is rotatably connected to the first frame 100 included in the first roof unit 1a, and the roof glass 11 included in the second roof unit 1b is rotatably connected to the second frame 101 included in the second roof unit 1b.

[0145] In another optional example, Figure 23 and Figure 24 As shown, Figure 23 and Figure 24 It is shown that the roof glass 11 included in the first roof unit 1a is rotatably connected to the first frame 100 included in the first roof unit 1a, and the roof glass 11 included in the second roof unit 1b is fixedly connected to the second frame 101 included in the second roof unit 1b.

[0146] In another optional example, Figure 23 and Figure 25 As shown, Figure 23 and Figure 25 It is shown that the roof glass 11 included in the first roof unit 1a is fixedly connected to the first frame 100 included in the first roof unit 1a, and the roof glass 11 included in the second roof unit 1b is rotatably connected to the second frame 101 included in the second roof unit 1b.

[0147] Based on the above examples, it is easy to understand that by matching and connecting the first connecting part 100c with the second connecting part 101c, the first roof unit 1a and the second roof unit 1b are matched and connected, and the first connecting seat 202 is used to connect the first connecting part 100c of the first roof unit 1a and the second connecting part 101c of the second roof unit 1b to the transverse frame 201, the connection adaptability between each roof unit 1 and the transverse frame 201 can be high, and the structural independence of each roof unit 1 is high. The structural setting of the roof unit 1 is more flexible and changeable, and can be suitable for meeting a wider range of design and usage requirements.

[0148] See also Figure 25In some embodiments, along the transverse arrangement direction of the plurality of roof units 1, two adjacent roof units 1 are respectively the third roof unit 1c and the fourth roof unit 1d, and the roof system 2 may further include a plurality of second connecting seats 203, the second connecting seats 203 including a third fixing portion 203a and a fourth fixing portion 203b spaced apart from each other, the third fixing portion 203a and the fourth fixing portion 203b are both fixedly disposed on the longitudinal frame 200, and a second fixed space is formed between the third fixing portion 203a and the fourth fixing portion 203b, and the third frame 103 of the third roof unit 1c is away from the roof glass. One end of the third frame 103 of the fourth roof unit 1d is connected to the third fixing portion 203a, and the end of the third frame 103 facing away from the roof glass 11 is connected to the fourth fixing portion 203b. By arranging a second connecting seat 203 on the longitudinal frame 200 to connect to the roof unit 1, the second connecting seat 203 can be adapted to be connected to the roof unit 1 by adjusting the shape of the second connecting seat 203. That is, there is no need to adjust the shape of the longitudinal frame 200. Only the shape of the second connecting seat 203 needs to be adjusted to make the longitudinal frame 200 suitable for connection to different roof units 1. The structure of the roof system 2 is flexible and has a wide range of applications. Exemplarily, the third fixing portion 203a is a steel plate in the shape of the third frame 103 adapted to the third roof unit 1c, and the fourth fixing portion 203b is a steel plate in the shape of the third frame 103 adapted to the fourth roof unit 1d. The third fixing portion 203a and the fourth fixing portion 203b are fixedly connected to the longitudinal skeleton 200 on one side facing away from the roof unit 1, so that the structure of the second connecting seat 203 is stable and suitable for bearing a larger load. By connecting the third fixing portion 203a and the fourth fixing portion 203b to the third roof unit 1c and the fourth roof unit 1d respectively, the structures of the third roof unit 1c and the fourth roof unit 1d can be made independent, thereby making the roof system 2 highly structurally flexible.

[0149] Optionally, along the transverse arrangement direction of the multiple roof units 1, the two adjacent roof glass panels 11 included in two adjacent roof units 1 can be fixedly connected to each bracket 10, or can be rotatably connected to each bracket 10, or, among the two adjacent roof glass panels 11, one roof glass panel 11 can be fixedly connected to the corresponding bracket 10, and the remaining roof glass panel 11 can be rotatably connected to the corresponding bracket 10.

[0150] In an optional example, Figure 25 As shown, Figure 25 It is shown that the roof glass 11 included in the third roof unit 1c is fixedly connected to the third frame 103 included in the third roof unit 1c, and the roof glass 11 included in the fourth roof unit 1d is fixedly connected to the third frame 103 included in the fourth roof unit 1d.

[0151] In another alternative example, Figure 26As shown, Figure 26 It is shown that the roof glass 11 included in the third roof unit 1c is rotatably connected to the third frame 103 included in the third roof unit 1c, and the roof glass 11 included in the fourth roof unit 1d is rotatably connected to the third frame 103 included in the fourth roof unit 1d.

[0152] Based on the above examples, it is easy to understand that by connecting the third fixing part 203a and the fourth fixing part 203b to the third roof unit 1c and the fourth roof unit 1d respectively, the connection adaptability between each roof unit 1 and the longitudinal frame 200 can be made high, and the structural independence of each roof unit 1 is high. The structural setting of the roof unit 1 is more flexible and changeable, and can be suitable for meeting a wider range of design and usage requirements.

[0153] In some embodiments, a second drainage channel 21 may be provided between two adjacent roof units 1 along the extension direction of the transverse frame 201. The extension direction of the second drainage channel 21 is the same as the extension direction of the longitudinal frame 200, so that water falling on the roof system 2 can flow to the second drainage channel 21 and flow to the outside of the roof system 2 through the second drainage channel 21. The drainage speed is fast, and the probability of water contacting the gaps between the components of the roof system 2 can be reduced, thereby effectively slowing down the aging speed of the sealant between the gaps between the components of the roof system 2, so that the roof system 2 can maintain good sealing and waterproof performance, thereby extending the service life of the roof system 2.

[0154] Optionally, the roof system 2 may further include a drainage component 22, which is provided with a drainage groove to form the second drainage channel 21. The drainage component 22 is located between the third frames 103 of two adjacent roof units 1 in the transverse arrangement direction, that is, between the third roof unit 1c and the fourth roof unit 1d, and the two opposite sides of the drainage component 22 are respectively connected to the two adjacent third frames 103, and the bottom of the drainage groove of the drainage component 22 is connected to the longitudinal frame 200, so that the longitudinal frame 200 can provide support for the drainage component 22 to make the drainage component 22 more stable.

[0155] Optionally, at this time, the third fixing portion 203a and the fourth fixing portion 203b are respectively located on two opposite sides of the drainage component 22, so that the third fixing portion 203a and the fourth fixing portion 203b are conveniently connected to the third roof unit 1c and the fourth roof unit 1d located on two opposite sides of the drainage groove.

[0156] Optionally, insulation material 23, such as insulation cotton, rigid polyurethane foam or glass wool, can be filled between the drainage component 22 and the longitudinal frame 200, between the drainage component 22 and the third fixing part 203a, and between the drainage component 22 and the fourth fixing part 203b, so that the connection between the two adjacent roof units 1 also has the insulation function, thereby further improving the insulation performance of the roof system 2.

[0157] It can be understood that when the roof unit 1 is formed with a first drainage channel 105, the second drainage channel 21 is connected to the first drainage channel 105, so that the water discharged from the second drainage channel 21 can be collected through the first drainage channel 105, and the water flowing into the first drainage channel 105 can be discharged to the outside of the roof system 2 through the second drainage channel 21, thereby realizing the diversion and rapid discharge of the accumulated water in the first drainage channel 105.

[0158] As mentioned above, the roof unit 1 may include an electric lock and an electric window opener 16, and the electric lock and the electric window opener 16 are electrically connected to an external power supply, and the electric lock and the electric window opener 16 may be partially routed along at least one of the first frame 100, the second frame 101 and the third frame 103. Optionally, the electrical connection wiring of the electric lock and the electric window opener 16 included in each roof unit 1 can be extended to converge at the roof frame 20, and routed along the longitudinal frame 200 and / or the transverse frame 201 until they are electrically connected to the external power supply, thereby making the electrical connection wiring of the roof system 2 regular and concise.

[0159] The present application provides a roof system 2 that, by providing a roof frame 20, can provide support for the roof units 1 and a base for installation and connection of the roof units 1, thereby facilitating the connection of multiple roof units 1 to form a roof. By using roof units 1 with functions such as space partitioning, daylighting, lighting, ventilation and smoke exhaust, thermal insulation, and earthquake and intrusion resistance to form a roof, the roof system 2 can integrate multiple functions, has a wide range of applications, and is highly safe to use. Furthermore, because the roof system 2 consists of the roof frame 20 and the finished roof units 1, the structure of the roof system 2 is regular and simple, the design difficulty of the roof system 2 is low, the construction process is simple, and the design and construction costs are low.

[0160] Furthermore, by arranging multiple roof units 1 longitudinally along the extension direction of the longitudinal skeleton 200, and reflecting the light emitted by the light-emitting member 13 of the roof unit 1 to the roof glass 11 of the adjacent roof unit 1 through the first surface 12a of the shielding member 12, a uniform lighting effect can be achieved for the adjacent roof units 1. The structure of the roof system 2 is reasonable and ingenious, and the lighting effect is good.

[0161] Furthermore, by providing a second drainage channel 21 extending along the extension direction of the longitudinal skeleton 200 between two adjacent roof units 1, and connecting the second drainage channel 21 to the first drainage channel 105 formed by the roof unit 1, water discharged from the second drainage channel 21 can be collected through the first drainage channel 105, and the water flowing into the first drainage channel 105 can be discharged to the outside of the roof system 2, thereby avoiding water accumulation in the roof system 2, slowing down the aging speed of the sealant in the gaps of the roof system 2, and avoiding water leakage of the roof system 2 due to the penetration of accumulated water, thereby maintaining the sealing and waterproof function of the roof system 2.

[0162] See also Figure 27 , Figure 27 This is a schematic block diagram of the structure of a building disclosed in the third aspect of the embodiments of the present application. The third aspect of the embodiments of the present application discloses a building 3 comprising a main building 30 and a roofing system 2 as described in the second aspect above, with the roofing system 2 being disposed above the main building 30. By utilizing a roofing system 2 that integrates functions such as space partitioning, daylighting, lighting, ventilation and smoke exhaust, thermal insulation, rapid drainage, and earthquake and intrusion resistance, the main building 30 can meet the operational requirements of the building 3 without requiring additional ventilation, smoke exhaust, drainage, or external lighting. This simplifies the structure of the main building 30, thereby simplifying the design and construction process of the main building 30 and reducing the design and construction costs of the main building 30. Furthermore, due to the simple and low-cost design and construction process of the roofing system 2, the overall design and construction of the building 3 can be simplified, reducing the overall design and construction costs of the building 3.
