Alternatively, 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, etc. Illustratively, the electric window opener 16 is a screw-type electric window opener 16, so that the electric window opener 16 has a large push-pull force and can be suitable for pushing and pulling large roof glass 11.

Referring to fig. 6, 7 and 9, in particular, the electric window opener 16 may include a fixing rod 160, an expansion rod 161 and a motor 162, one end of the fixing rod 160 may be rotatably connected to the bracket 10, the fixing rod 160 has an accommodating cavity 163, one end of the expansion rod 161 is slidably connected to the accommodating cavity 163 along an extending direction of the fixing rod 160, the other end of the expansion rod 161 is located at the other end of the fixing rod 160, the other end of the expansion rod 161 is rotatably connected to the protective frame 15, the motor 162 is at least partially disposed in the accommodating cavity 163 and located at one end of the fixing rod 160, the motor 162 is electrically connected to an external power source, an output end of the motor 162 is threadedly connected to one end of the expansion rod 161, the motor 162 is configured to drive one end of the expansion rod 161 to slide along the extending direction of the fixing rod 160 through a screw transmission, so that the expansion rod 161 performs an expansion and contraction movement relative to the fixing rod 160, when the telescopic rod 161 extends out of the fixing rod 160, the other end of the telescopic rod 161 pushes the protection frame 15 to drive the roof glass 11 to be away from the opening 102a through the protection frame 15, so that the roof glass 11 is in an opening posture, and when the telescopic rod 161 retracts into the fixing rod 160, the other end of the telescopic rod 161 pulls the protection frame 15 to drive the roof glass 11 to move towards the opening 102a through the protection frame 15, so that the roof glass 11 moves to cover the opening 102a, and the roof glass 11 is in a covering posture.

In some embodiments, the roof unit 1 may further include an electric lock (not shown) disposed on the support 10 and electrically connected to an external power source, wherein the electric lock is configured to automatically lock and connect to the protective frame 15 when the roof glass 11 is in the covering posture, so as to lock the protective frame 15 to the support 10, thereby providing a greater locking force for maintaining the glass roof in the covering posture, so that the roof unit 1 can be maintained in the covering posture under the action of a greater external force (e.g., wind force, vibration force). It will be appreciated that when the roof glass 11 needs to be switched from the closed position to the open position, the electric lock can be automatically unlocked to release the protective frame 15 from the support 10. Alternatively, the electrical connection between the electric lock and the external power source may be routed partially along the rack 10, thereby making the routing of the electrical connection neat and concise.

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., so that the number of locking points between the electric lock and the protective frame body 15 is increased, the locking force applied by the electric lock to the protective frame body 15 is larger, the acting area is larger, the action of the locking force is more average, and the locking connection between the roof glass 11 and the support 10 is more stable.

Referring to fig. 1 and 10 together, in some embodiments, the support 10 may further include a third frame body 103, the third frame body 103 is connected between the first frame body 100 and the second frame body 101, and an extending direction of the third frame body 103 is perpendicular to the extending directions of the first frame body 100 and the second frame body 101, so that the relative position between the first frame body 100 and the second frame body 101 can be fixed by the third frame body 103, and thus the support 10 is integrally formed into a stable shape structure to better provide a stable supporting force for the roof glass 11.

Alternatively, the third frame 103 may be a long hollow rod structure made of hollow section bar (such as hollow aluminum section bar or stainless steel section bar) or the like, so that the third frame 103 has certain strength to make the support 10 capable of being used for bearing the roof glass 11, and at the same time, the weight of the whole support 10 can be reduced to reduce the weight of the roof unit 1 and the load of the building.

Optionally, the number of the third frame bodies 103 may be multiple, and multiple third frame bodies 103 are arranged at intervals along the extending direction of the first frame body 100 and the second frame body 101, and by increasing the number of the third frame bodies 103, the fixing effect of the third frame bodies 103 on the first frame body 100 and the second frame body 101 can be enhanced, so as to further enhance the overall stability of the support 10.

As shown in fig. 10, optionally, a third bearing surface 103a is further formed at a third top of the third frame body 103, the third bearing surface 103a is located on one side of the roof glass 11 facing the opening 102a, the third bearing surface 103a is connected to the roof glass 11, the third bearing surface 103a bears the roof glass 11, and the connection area between the third frame body 103 and the roof glass 11 can be increased, so that the bearing stability of the third frame body 103 on the roof glass 11 is enhanced, the pressure at the connection position between the third frame body 103 and the roof glass 11 is reduced, the roof glass 11 is prevented from being damaged due to excessive local stress, and the use safety of the roof unit 1 is improved.

As described above, the parts included in the roof unit 1 may be filled or coated with the silicone weather-resistant sealant 14a to fill and seal gaps between the parts included in the roof unit 1, so that, in order to facilitate the waterproof and sealing at the edge of the roof glass 11, the third supporting surface 103a of the third frame body 103 may be disposed corresponding to the edge of the roof glass 11, and the space between the third supporting surface 103a and the roof glass 11 may be filled with the silicone weather-resistant sealant 14 a.

It should be noted that the first frame 100, the second frame 101, and the third frame 103 may all be formed with bearing surfaces, or some of the first frame 100, the second frame 101, and the third frame 103 may be formed with bearing surfaces, 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 first frame 100 is formed with the first bearing surface 100d, etc. It can be understood that, when the first frame body 100, the second frame body 101 and the third frame body 103 are all formed with bearing surfaces, that is, the first frame body 100 is formed with a first bearing surface 100d, the second frame body 101 is formed with a second bearing surface 101d, and the third frame body 103 is formed with a third bearing surface 103a, the connection area between the support 10 and the roof glass 11 is the largest, the support effect of the support 10 on the roof glass 11 is the most stable, the pressure between the support 10 and the roof glass 11 is the smallest, the local bearing force applied to the roof glass 11 is the smallest, and the safety in use of the roof unit 1 is the highest.

Referring to fig. 11, as mentioned above, when the roof glass 11 is rotatably connected to the bracket 10, the roof unit 1 may include a buffer sealing member 141 disposed between the bracket 10 and the roof glass 11. Optionally, when the roof unit 1 includes the third frame 103, the buffer sealing element 141 may be further disposed between the protection frame 15 and the third supporting surface 103a, and the specific arrangement and usage effect of the buffer sealing element 141 between the protection frame 15 and the third supporting surface 103a may refer to the foregoing description, which is not repeated herein.

Further, at this moment, the roof unit 1 may further include an electric window opener 16 and an electric lock, and the electric connection between the electric window opener 16 and the electric lock and the external power supply may partially run along the wire of the bracket 10, so that when the roof unit 1 further includes the third frame body 103, the electric window opener 16 and the electric connection between the electric lock and the external power supply may partially run along the wire of at least one of the first frame body 100, the second frame body 101, and the third frame body 103, thereby making the electric connection run neat and simple.

Referring to fig. 2, fig. 3 and fig. 12, as mentioned above, the roof unit 1 includes the shielding member 12 and the light emitting member 13, the shielding member 12 is connected to the first top portion 100a of the first frame 100 and is located at a 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 portion 100b of the first frame 100, the first surface 12a is at least partially formed as a light reflecting surface, the light emitting member 13 is located at the first bottom portion 100b of the first frame 100 and is located at a side of the first frame 100 away from the light transmitting space 102, and a light emitting end of the light emitting member 13 faces the first surface 12 a.

Alternatively, the shielding member 12 may extend along the extending direction of the first frame 100, so that the shielding area of the shielding member 12 is large and the shielding effect is good.

In some embodiments, the first surface 12a may be an inclined surface, the first surface 12a is inclined gradually from a side connected with the first frame 100 to another side away from the first frame 100, so that the thickness of the shielding member 12 is gradually reduced, and thus the shielding member 12 uses less material and is manufactured at a lower cost, and the volume and weight of the shielding member 12 are gradually reduced from a side connected with the first frame 100 to a side away from the first frame 100, and the first frame 100 supports the shielding member 12 more stably, and the shielding member 12 is not easily separated from the first frame 100 due to external force (such as wind force), so that the structure of the roof unit 1 is more stable, and the use safety is higher. More specifically, the first surface 12a is formed as an inclined surface, and the light path of the light reflected by the first surface 12a can be adjusted by adjusting the inclination degree of the first surface 12a, so that the light emitted from the light-emitting member 13 is reflected by the first surface 12a, and the light is irradiated to the roof glass 11 included in the other roof unit 1 to form an effect similar to wall washing. For example, when the roofing unit 1 is applied to a roofing system, the roofing system may have a plurality of roofing units 1, the plurality of roofing units 1 being arranged adjacent to each other in sequence. Taking two adjacent roof units 1 as a first roof unit 1a and a second roof unit 1b as an example, light emitted from the light-emitting member 13 is reflected by the first surface 12a of the first roof unit 1a to be reflected to the second roof unit 1b, so that a lighting effect similar to wall washing can be formed on the second roof unit 1 b.

More specifically, when the roof glass 11 is rotatably connected to the bracket 10, the first surface 12a is formed as an inclined surface, so that the space occupied by the shielding member 12 can be reduced, the roof glass 11 is avoided, the rotation angle of the roof glass 11 relative to the bracket 10 can be larger, and the smoke exhaust and ventilation efficiency of the roof unit 1 is higher when the roof glass 11 is in the opened posture.

Optionally, the shielding member 12 may be a strip-shaped hollow section bar made of metal materials such as aluminum, iron, or steel, or a structure formed by bending a thin plate, so that the shielding member 12 has good toughness and deformation resistance, and at the same time, the weight of the shielding member 12 is reduced, so that the shielding member 12 is more easily and stably connected to the first frame body 100, the overall weight of the roof unit 1 can be reduced, and the structure of the roof unit 1 is lighter. Further, by forming the shield 12 using metal, the first surface 12a can be formed as a light reflecting surface by utilizing high reflectivity of metal to light. It will be appreciated that in other embodiments, the first surface 12a may also be formed as a light reflecting surface by providing a light reflecting film layer, such as a metal film layer, a microprismatic light reflecting film, or a glass bead light reflecting film, on the first surface 12a of the mask 12.

As shown in fig. 12, in some embodiments, a water leaking port 120 may be disposed on a side of the shielding member 12 close to the first frame 100, and the water leaking port 120 is used for allowing water on the surface or inside of the roof unit 1 to flow to the outside of the roof unit 1 timely and quickly, so as to prevent water from being accumulated in the roof unit 1, so as to prevent water from penetrating into gaps between components of the roof unit 1, and the silicone weather-resistant sealant 14a in the gap is contacted to cause aging of the silicone weather-resistant sealant 14a and accelerated sealing performance degradation, so as to prevent water from leaking from the roof unit 1, and thus the service life of the roof unit 1 can be prolonged.

Optionally, the water leakage opening 120 may be filled with a dustproof and water-permeable material, such as a sponge, a dustproof mesh, a dustproof cloth, etc., so as to prevent dust from passing through the water leakage opening 120 while not affecting the water leakage performance of the water leakage opening 120, thereby preventing dust from entering the inside of the shielding member 12 or circulating inside the shielding member 12.

Specifically, when the shielding member 12 is a strip-shaped hollow section, the shielding member 12 includes a hollow portion 121, the water leakage port 120 may include a first water leakage port 120a, the first water leakage port 120a is disposed on a side of the shielding member 12 facing the first bottom 100b of the first frame 100, the hollow portion 121 is communicated with an external space of the shielding member 12 facing the first bottom 100b through the first water leakage port 120a, and the first water leakage port 120a is used for allowing water penetrating or flowing into the hollow portion 121 to be discharged to the outside of the hollow portion 121, so as to prevent the water from being accumulated in the hollow portion 121, which results in an increase in weight of the shielding member 12, which affects connection stability of the shielding member 12 and the first frame 100, and also does not cause deterioration or mosquito breeding due to long-term accumulation of water, which affects a sanitary environment of a building.

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, 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 for being matched and connected with the second connecting portion 101c included in the other roof unit 1, the second connecting portion 101c is used for being matched and connected with the first connecting portion 100c included in the other roof unit 1, 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 on the first top 100a of the first frame 100, as shown in fig. 12, fig. 12 shows a partial structure when the first connecting portion 100c and the second connecting portion 101c included in the two adjacent roof units 1 are respectively connected. It will thus be readily appreciated that the covering 12 may now be located above the first drainage channel 105 comprised by the adjacent roof unit 1, so that for a more rational drainage of standing water the first drainage opening 120a should be located towards the first drainage channel 105 of the adjacent roof unit 1, so that standing water drained through the first drainage opening 120a can fall towards the first drainage channel 105, rather than towards the roof glass 11 of the adjacent roof unit 1.

Optionally, the hollow portion 121 may be multiple, and the water leakage port 120 may further include a second water leakage port 120b, where the second water leakage port 120b is communicated between two adjacent hollow portions 121, and the second water leakage port 120b is used for allowing water in the hollow portions 121 to circulate between the multiple hollow portions 121, so that water permeating into one of the hollow portions 121 may flow to the 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 120 a.

Optionally, the water leaking port 120 may further include a third water leaking port (not shown), the third water leaking port is disposed on a side of the shielding member 12 facing the first top portion 100a of the first frame 100, the hollow portion 121 is communicated with an external space of the shielding member 12 facing the first top portion 100a through the third water leaking port, the third water leaking port is used for allowing water sprinkled onto the roof glass 11 or the shielding member 12 to flow into the hollow portion 121, so as to prevent the water from being accumulated on the surface of the roof unit 1, thereby reducing the load of the roof glass 11 or the shielding member 12, reducing the possibility of water penetrating into the joints between the components of the roof unit 1, and preventing the silicone weather-resistant sealant 14a filled in the joints of the components from rapidly aging, thereby prolonging the service life of the roof unit 1. So that when water is scattered onto the roof glass 11 or the screen 12, the water can be rapidly discharged to the outside of the roof unit 1 through the third and second drain holes 120b and the first drain hole 120a in order.

Referring to fig. 3, 5 and 12, in some embodiments, the light emitting element 13 may be located on a side of the shielding element 12 connected to the first frame 100, so that on one hand, the shielding element 12 can shield the light emitting element 13 more widely and the shielding effect is better, and on the other hand, a larger part of the light emitted by the light emitting element 13 can be emitted to the first surface 12a of the shielding element 12, so that more light can be reflected to the roof glass 11 by the first surface 12a, and the lighting effect of the light emitting element 13 is brighter.

Optionally, the light emitting element 13 may be a light-emitting diode (LED) strip or a lamp bead, so that the light emitting element 13 has a good illumination effect and low energy consumption. Use illuminating part 13 as LED lamp area as an example, illuminating part 13 can send even bar light, and illuminating part 13 can take place certain deformation to make illuminating part 13 be suitable for the bar light that produces more kinds of shapes, perhaps be suitable for and be applied to different shape surfaces, simultaneously, because the lamp pearl in LED lamp area and circuit all are wrapped up in flexible plastic, consequently illuminating part 13 has better waterproof, insulating properties, is applicable to outdoor environment.

In some embodiments, the first bottom 100b of the first frame 100 may be provided with an open lamp groove 130 facing the first surface 12a, the light emitting member 13 is installed in the lamp groove 130, by providing the lamp groove 130, an installation space can be provided for the light emitting member 13, a part of the periphery of the light emitting member 13 is shielded to protect the light emitting member 13, a fixed reference is provided for the light emitting member 13 to fix the shape of the light emitting member 13, and light emitted from the light emitting member 13 can be reflected by the groove wall of the lamp groove 130 to reflect a part of the light emitted to the groove wall of the lamp groove 130 to the first surface 12a, thereby further enhancing the lighting effect of the roof unit 1.

It is understood that the light trough 130 may be an elongated light trough, and the extending direction of the light trough 130 is the same as the extending direction of the shielding member 12, so that the light emitting member 13 installed in the light trough 130 can extend along the extending 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 to ensure that the shielding member 12 always provides a shielding effect for the light emitting member 13.

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

Referring to fig. 11 to 13, in some embodiments, at least a portion of the surface of the roof glass 11 facing the opening 102a may be covered with a reflective layer 110, and the reflective layer 110 is used for reflecting light to the outside of the roof unit 1, so that a user can more obviously observe the light emitting effect of the roof unit 1 from the outside of the roof. Alternatively, the light reflecting layer 110 may be formed in an image or a gradation pattern, so that the light reflected by the light reflecting layer 110 may form a bright image or a gradation pattern. Further, when the reflective layer 110 is used to form an image or a gradual pattern, the reflective layer 110 may be a discontinuous layer, that is, the reflective layer 110 only covers a part of the surface of one side of the roof glass 11 facing the opening 102a, so that the part of the roof glass 11 not covered with the reflective layer 110 has better light transmittance, and the roof unit 1 can realize a certain lighting function inside a building.

Optionally, the reflective layer 110 may reflect one or more colors, so that the user can observe the one or more colors after the light emitted from the light emitting element 13 is reflected by the reflective layer 110. It can be understood that the reflective layer 110 can be formed as an image or a gradient pattern and simultaneously reflect one or more colors of light, so that the light emitted by the light emitting element 13 is reflected by the reflective layer 110, so that the roof glass 11 can present a single-color or multi-color bright pattern, and a wider variety of lighting effects can be realized.

Optionally, the reflective layer 110 may be located on a side of the roof glass 11 facing the inside of the building, so as to prevent the reflective layer 110 from being hit or scratched by wind, rain, sand, soil, dust, or the like, so as to reduce the possibility that the luminescent layer is separated from the roof glass 11, and effectively prolong the service life of the luminescent layer.

In some embodiments, the reflective layer 110 can be a colored glaze layer, a glass colored film layer or a metal film layer, so that the reflective layer 110 can be coated on the surface of the roof glass 11, and the reflective layer 110 can perform the function of reflecting light of one or more colors. Illustratively, the light reflecting layer 110 may be a colored glaze layer, so that the light reflecting layer 110 has wear resistance, acid and alkali resistance, long service life, and is easy to form patterns with different colors and different shapes, and has a wide application range.

As shown in fig. 13, optionally, the roof glass 11 may further be provided with a low-emissivity layer 111, the low-emissivity layer 111 is disposed 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 disposed on the reflective layer 110, and is disposed on the surface of the remaining part of the roof glass 11 which is not covered with the reflective layer 110, so that the low-emissivity layer 111 more completely covers the surface of the roof glass 11, and the low-emissivity layer 111 is used for reducing the heat transfer emissivity of the roof glass 11, so as to reduce the heat exchange efficiency between the internal space and the external space of the building, so as to reduce the radiation speed of heat from the outside of the building to the inside of the building when the temperature of the external space of the building is higher than that of the internal space of the building, and reduce the radiation speed of heat from the inside of the building to the outside of the building when the temperature of the external space of the building is lower than that of the internal space of the building, therefore, the heat preservation effect of the building is good, and the energy consumption of air conditioning cold air or warm air of the building can be reduced.

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

Illustratively, the Low radiation layer 111 may be a Low-e (Low Emissivity) film layer including a metallic silver film layer, so as to utilize the good radiation protection performance of metallic silver to realize the function of the Low radiation layer 111 of reducing the heat exchange efficiency between two opposite sides of the Low radiation layer 111, and meanwhile, since only a trace amount of metallic silver is needed to realize the effect of reducing the heat exchange efficiency, the metallic silver film layer may be thinner, so that the light transmittance of the Low radiation layer 111 is better, thereby ensuring the light transmittance of the roof glass 11, and ensuring the lighting effect of the roof glass 11.

As shown in fig. 11 and 13, in some embodiments, the roof glass 11 may further include a first glass 112, a second glass 113, and a sealing member 114, the first glass 112 and the second glass 113 are spaced apart from each other to form an air layer 115 therebetween, the first glass 112 is located above the second glass 113, the sealing member 114 is located at an edge of the first glass 112 and the second glass 113, and the sealing member 114 is located between the first glass 112 and the second glass 113 to separate the air layer 115 from an external space of the roof glass 11, so as to prevent impurities such as water and dust from entering the air layer 115, and prevent air in the air layer 115 from convecting with air outside the roof glass 11, thereby being able to further improve a heat insulation effect of the roof glass 11 by using a property of air as a poor heat conductor.

Optionally, the air layer 115 may be filled with dry inert gas, so as to avoid a chemical reaction between the first glass 112 and the second glass 113, which may result in a change of the properties of the roof glass 11, for example, a mold may be generated between the first glass 112 and the second glass 113, which may result in a decrease of the light transmission and reflection properties of the roof glass 11, and a dirty appearance.

Further, when the roof unit 1 is used in a building, the second glass 113 is located on a side of the first glass 112 facing the inside of the building, the light reflecting layer 110 may be located on a side surface of the first glass 112 facing the second glass 113, and the low radiation layer 111 is located on a side surface of the first glass 112 and the light reflecting layer 110 facing the second glass 113, that is, the surface of the low radiation layer 111 is located facing the air layer 115, so as to prevent the low radiation layer 111 from contacting the outside air of the roof glass 11, thereby preventing the low radiation layer 111 from contacting water vapor, sulfide or oxide through air and causing chemical reaction, causing the low radiation layer 111 to lose radiation resistance, and causing the low radiation layer 111 to have a blackened appearance, discolored, and gradually appearing a large number of mold spots, so as to achieve a function of prolonging the service life of the low radiation layer 111.

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 the first glass 112 and the second glass 113 are laminated glass, and since the laminated glass has high strength, the laminated glass can resist large vibration and impact, for example, impact of stones rolled up by airflow, so that the roof glass 11 can protect the interior space of a building, and the roof glass 11 is not easy to break and has a long service life. Even if the laminated glass is broken, the broken glass and the sharp small glass fragments are still adhered to the intermediate film of the laminated glass, namely, the fragments of the glass cannot be dispersed, so that the glass cannot fall into the building, the fragments can be prevented from impacting and injuring personnel in the building, and the safety of the roof glass 11 is high.

As shown in fig. 11 and 13, taking the second glass 113 as the laminated glass as an example, as described above, the second glass 113 is located on the side of the first glass 112 facing the interior of the building, and therefore, when the second glass 113 is made of the laminated glass, it is possible to prevent glass fragments from falling when the second glass 113 is broken, and at the same time, it is possible to prevent the glass fragments generated by the first glass 112 from falling into the interior of the building when the first glass 112 is broken, thereby improving the safety of the roof unit 1 in use.

In some embodiments, the roof glass 11 may be fixedly attached to the support frame 10, or the roof glass 11 may be rotatably attached to the support frame 10.

As shown in fig. 3, 4 and 10, in an alternative 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.

Optionally, the roof glass 11 may be fixedly connected to the bracket 10 by at least one of a structural adhesive and a double-sided adhesive, so that the connection between the roof glass 11 and the bracket 10 is more stable and firm, and thus the roof glass 11 is not easily separated from the bracket 10, and the use safety of the roof unit 1 is high.
