Abstract

PROBLEM TO BE SOLVED: To solve the following problem: a conventional automobile has a structure in which the inside of the automobile is susceptible to intrusion of heat in summer and in which the heat within the automobile is easily released in winter.SOLUTION: An iron plate part of an automobile body has a double structure comprising outer and inner plates, internally has a hollow part, and has a structurally-sealed peripheral connection part. The hollow part is evacuated, and the inner or outer plate is provided with an extractor connection part for evacuating the inside. Additionally, an outer plate cover is provided on an outer plate of a roof to be movable upward and downward.SELECTED DRAWING: Figure 1

Description

  TECHNICAL FIELD The present invention relates to a vehicle body and a roof of a vehicle that prevent solar heat from entering the interior of a vehicle in the summer and prevent indoor heat from escaping in the winter.

  Conventionally, when the automobile is exposed to direct sunlight, the temperature in the room rapidly increases. For this reason, when parking, it was usual to choose a shade and park.

  In winter, it was easy for the indoor heat to escape, and when the heating was turned off, the room suddenly became cold. As countermeasures against this, only a heat insulating material was put on the interior side of the vehicle body.

  As described above, the conventional automobile has a structure in which heat easily enters the room in summer and the heat in the room easily escapes in winter.

  As described above, the conventional automobile has a problem that heat easily enters the room in summer, and heat in the room easily escapes in winter.

    The present invention is intended to solve the problems of such a conventional structure, and provides an automobile that prevents solar heat from entering in the summer and prevents indoor heat from escaping in the winter. It is intended.

  In order to achieve the above object, the present invention comprises a body iron plate part composed of an outer plate and an inner plate, a space between the outer plate and the inner plate as a hollow part, a peripheral connection part as a sealed structure, and a hollow part as a vacuum. Or, the bleeder connection part for evacuating the inside of the outer plate is provided. As a second solution, the outer plate cover is provided on the roof outer plate so that the outer plate cover can be moved up and down. It is attached.

The operation of the above problem solving means is as follows.
By making the steel plate part of the vehicle body double and making the inside vacuum, the vacuum of the hollow part prevents solar heat from entering in the summer and prevents the indoor heat from escaping in the winter.

  In addition, by providing an outer cover that can be moved up and down on the outer skin of the roof, even when parked in a place exposed to direct sunlight, the outer cover can be moved upward so that it can be directly exposed to the roof skin. It is not exposed to sunlight and realizes a further heat insulating effect.

  As described above, the vehicle body of the present invention has the effect of preventing solar heat from entering the room in the summer and preventing the indoor heat from escaping outside in the winter. Changes can be kept gradual.

  Moreover, since the load required for the air conditioning of the engine is small, it contributes to energy saving and helps to prevent global warming.

  Further, since the large-sized bus has a structure in which the area of the iron plate portion is wide and heat easily enters and escapes easily, the use of the present invention in the large-sized bus has a greater effect.

Also, the large bus has a luggage room on the lower floor of the passenger seat and puts luggage bought during travel, but even with ice and dry ice attached, it can be traveled for 4 days, 5 days, 1 week If so, the souvenirs you bought may not be eaten, but in the present invention, the heat penetration is slow even in summer, and the effect of ice or dry ice can be maintained for a long time.

The degree of vacuum of the hollow part 4 can be maximized by checking the degree of vacuum during periodic inspection of the vehicle and recording the state.

  As for the iron plate part with a large area such as the roof of a large bus, there is a part where the vacuum degree cannot be maintained by dividing the hollow part 4 into a plurality of blocks and providing the bleeder connection part 5 in each block. Can minimize the damage.

  On the roof covering 6, an interlock is set so that it is impossible to run when it is in the “raised” position because it has a high air resistance when running in the “raised” position and is dangerous on a tunnel or bridge. To prevent accidents

  The operation of the confirmation display device and the vertical drive device as to whether the roof covering 6 is in the “up” position or the “down” position can be secured by installing it in the driver's seat.
