AI Technical Summary
Conventional car roofs fail to maintain a comfortable and safe interior temperature, especially when exposed to direct sunlight, leading to high temperatures that can spoil food, pose safety risks from falling rocks, and discomfort for passengers.
A 5-cm-high protrusion on the roof with a heat-insulating material and a cooling system using air intake to lower the temperature.
The double-layered and insulated roof effectively reduces interior temperature, enhancing passenger comfort and safety from falling objects.

Abstract
Description
[Technical Field]
[0001] This invention is an automobile interior high temperature prevention roof that reduces the temperature inside the automobile and is eco-friendly in preventing accidents such as falling rocks from above inside the automobile. [Background technology]
[0002] Conventionally, cars have thin, single-layer roofs, which means that direct sunlight is strong, and when the outside temperature is 30 degrees, the temperature inside the car can reach 45 to 48 degrees. This can cause food to spoil, and there are also fires caused by pets, small children, and lighters. It is also very hot and uncomfortable to ride in (see Patent Document 1). [Prior art documents]
[0003] [Patent documents] [Patent documents] Patent Publication No. 0000-000000 Summary of the Invention [Problem to be solved by the invention]
[0004] Not only when the car is parked, but also when it is not too hot inside, you want to keep it at a low temperature so that you can safely leave small children, pets, and food inside, make it comfortable when you are inside, and prevent accidents from falling rocks from above. [Means for solving the problem]
[0005] A 5-cm-high protrusion (4) is provided on the roof of a conventional car, and a heat insulating material (5) is placed on top of it, and cold air is blown in from the front air intake (2) through the atrium (6) to cool the lower roof (7), further lowering the temperature inside the car as it moves. [Effects of the Invention]
[0006] The double-layered and insulated roof lowers the temperature inside the vehicle, making it more comfortable for passengers and safer from falling objects. [Brief explanation of the drawings]
[0007] [Figure 1] FIG. 1 is a plan view of a car roof. [Figure 2] FIG. 1 is a side view of the rear roof of a vehicle. [Figure 3] A side view of the roof of the car. MODE FOR CARRYING OUT THE INVENTION
[0008] A 5 cm high protrusion (4) is provided on the roof of the car, and a heat insulating material (5) is placed on top of it. Cool air from the front air intake (2) passes through the void (6) to cool the lower roof (7), and the temperature inside the car further drops when the car is running.

Claims
[Claim 1] A 5cm high protrusion (4) is placed on top of the roof of a conventional car, with heat insulation (5) placed on top of it, and cool air is blown in from the front wind intake (2) through the vent (6) to cool the lower roof (7), further lowering the temperature inside the car as the car moves.
