DETAILED DESCRIPTION

[0034] The present invention will be further described in detail below with reference to the accompanying drawings.

[0035] like Figure 1-3 As shown, the utility model discloses a heat dissipation type natural ventilation skylight, comprising:

[0036] Skylight base 1;

[0037] The support assembly includes a support rib 2 provided on the skylight base 1, and the support rib 2 is provided at multiple locations along the first direction and the second direction;

[0038] A rain shield assembly includes three layers of rain shields, the rain shields are arranged along a first direction and have a length covering the entire skylight;

[0039] The valve plate 3 is horizontally arranged between the supporting ribs 2, and a driving assembly is installed on the lower side to drive the valve plate 3 to move up and down to open and close.

[0040] The advantage of adopting the above technical solution is that the skylight has good ventilation performance, and at the same time, the valve plate 3 can be moved up and down to effectively prevent rain, snow, sand and dust from entering. It has high structural strength, simple structure and easy assembly.

[0041] In some embodiments, the flashing assembly includes: an upper flashing plate 4, positioned above the supporting ribs 2; a middle flashing plate 5, positioned between the two supporting ribs 2 and located in the middle of the supporting ribs 2; and a water channel 6, located below the supporting ribs 2 and secured to the skylight base 1. The upper flashing plate 4 and the middle flashing plate 5 are connected by self-tapping screws, providing high strength and wind resistance. The middle flashing plates 5 and the upper flashing plates are alternately positioned to effectively protect against rain.

[0042] Compared with the single-layer rain shield in the prior art, the present application sets an upper rain shield 4, a middle rain shield 5 and a water gutter 6 to achieve a three-layer rain shield function, which plays a role in protecting against rain, snow, sand and dust. At the same time, the setting of the water gutter 6 plays a role in diverting rainwater to flow out from the side.

[0043] In some embodiments, the support ribs 2 are symmetrically arranged and fixed by a middle partition 21. The upper and lower ends of the support ribs 2 protrude outward, and the middle is concave inward. At the same time, a slope 22 for installation is provided. The support ribs 2 adopt a fishbone arrangement structure, which has high structural strength and good rain protection.

[0044] The symmetrically arranged supporting ribs 2 are used to fix the rain shield assemblies on both sides. They have great strength, light weight and are easy to install. The upper rain shield 4, the middle rain shield 5 and the gutter 6 are consistent with the roof drainage direction.

[0045] In some embodiments, a bending portion 61 is provided on both sides of the water tank 6, which is bent upward along both sides of the supporting rib 2. The top of the bending portion 61 is inclined toward the valve plate 3, and the valve plate 3 is located on the upper side of the bending portion 61. In order to ensure the lighting performance of the valve plate 3, the valve plate 3 can be made of FRP lighting board or PC lighting board. If no lighting is required, it can be made of aluminum plate or color plate. A sealing strip is also provided on the upper side of the bending portion 61 to ensure the sealing performance of the valve plate 3.

[0046] Rain, snow, sand and dust falling on the valve plate 3 flow into the water trough 6 and flow out through the water trough 6, effectively preventing rain, snow, sand and dust from entering the interior of the skylight.

[0047] Furthermore, the water tank 6 is connected to the skylight base 1 through a fixing plate 62. The fixing plate 62 is L-shaped as a whole, and is fixed to the water tank 6 by screws on the side and fixed to the skylight base 1 on the bottom. The fixing plate 62 ensures that the upper surface of the water tank 6 is not nailed or glued, effectively ensuring the waterproof performance of the water tank 6.

[0048] In some embodiments, the driving assembly includes: a crank-connecting rod mechanism arranged on the lower side of the valve plate 3, a connecting rod 7 is arranged between the multiple crank-connecting rods, the connecting rod 7 is driven by a driving member 71, and the driving member 71 drives the connecting rod 7 to move horizontally, driving the crank-connecting rod mechanism to move up and down to lift or drop the valve plate 3, thereby realizing the automatic opening and closing function of the sunroof. The driving member 71 can be an electric push rod, which is convenient to control and has a long service life.

[0049] A crank-connecting rod mechanism is provided to drive the valve plate 3 to rise and fall, and multiple crank-connecting rod mechanisms are driven by the same driving member 71 to realize linkage control of the sunroof, facilitate opening and closing of the sunroof, and have convenient assembly, stable driving and long service life.

[0050] Furthermore, a middle support plate 23 is provided between the supporting ribs 2, and the middle rain shield 5 is fixed on the middle support plate 23. The middle support plates 23 are arranged at intervals for installing the middle rain shield 5, which facilitates the fixing of the rain shield and ensures the structural strength of the entire skylight.

[0051] Furthermore, the crank-connecting rod mechanism includes a connecting rod member 72, a crank rod 73 and a linkage rod 74. The connecting rod member 72 is hinged at both ends of the valve plate 3, the crank rod 73 is hinged to the connecting rod member 72, and the linkage rod 74 is arranged along the length direction of the valve plate 3 to connect the crank rod 73 installed on both sides of the valve plate 3. The connecting rod 7 connects the middle parts of multiple linkage rods 74, so that the multiple linkage rods 74 move left and right together, thereby realizing the common opening and closing of multiple valve plates 3.

[0052] The crank-connecting rod mechanism is connected by a linkage rod 74, so that the switches on both sides of the valve plate 3 are opened at the same time, ensuring protection against rain, snow, sand and dust, and extending the service life.

[0053] A guide rail 75 is provided on the side of the crank rod 73, and the guide rail 75 is vertically installed on the sunroof base 1. A slider is provided on the guide rail 75. The crank rod 73 is connected to the slider and moves up and down along the guide rail 75. The slider controls the movement of the crank rod 73, and the connecting rod 72 is pushed upward to achieve a stable lifting of the valve plate 3. At the same time, the valve plate 3 opens smoothly and quickly.

[0054] Furthermore, outer protective plates 11 and flashing plates 12 are provided on both sides of the skylight base 1 .

[0055] The benefit of adopting the above technical solution is that the setting of the outer protective plate 11 plays a protective role, and the flashing plate 12 guides the water on the water tank 6 to the roof, effectively preventing rain and snow from flowing back into the skylight.

[0056] When it is necessary to open, the electric push rod extends to drive the connecting rod, which further drives the linkage rod 74 to move. At this time, the crank-connecting rod mechanism lifts up to open the valve plate 3 to realize the ventilation function. When it is necessary to close, the electric push rod is retracted, the valve plate 3 drops and the skylight is closed. During the opening process, the setting of the upper rain shield 4, the middle rain shield 5 and the water tank 6 effectively reduces the rainwater from entering the skylight. It has a simple structure, easy assembly, high connection strength, low driving energy consumption, stable driving and long service life.

[0057] For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
