Abstract

PURPOSE:To provide a car body in which a light receiving condition and a running condition are most rationalized by forming an electric automobile (a solar car) run through conversion of solar beams into electric energy so that worsening of environment, such as the generation of exhaust gas, noise, vibration, occurring during running of a conventional automobile is prevented from occurring. CONSTITUTION:Wing section type base sheets 3, 3', 3'', and 3''' are arranged vertically in two stages to a drum body part 2 of a car body and a solar battery panel film 1 is attached on the upper surface thereof to form wing section solar panels 4, 4', 4'', and 4'''. The upper stage wing section type solar panels 4 and 4' are coupled to the face parts on both sides of the drum body part 2 by means of pins and through vertical rotation operation, running in a posture optimum to receipt of light and running is practicable. The rear edge part of the wing section type solar panel are formed so as to operate as flaps 5, 5', 5'', and 5'''. During running, an air lift similar to that of an aircraft is generated and the weight of a car body is positively reduced.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle which uses a solar cell as a driving force, instead of a conventional vehicle which uses an internal combustion engine (gasoline engine, diesel engine, etc.) as a prime mover.

[0002]

2. Description of the Related Art Conventionally, solar cells (solar panels) used to drive automobiles are amorphous.
Although the energy conversion efficiency of silicon-based panels is about 8 to 10%, crystalline silicon solar cells (energy conversion efficiency of about 12 to 18%) will be put to practical use in order to enhance this energy conversion effect. Next, gallium arsenide-based solar cells (energy conversion efficiency is 1
8 to 20%) is about to be put to practical use,
At present, the price is extremely high, so cost reduction is being attempted. As described above, it is necessary to improve the energy conversion efficiency of the solar panel, and at the same time, research on the body structure body regarding the form of the solar panel and the difficulty of traveling.

[0003]

In order to fundamentally improve the current environmental degradation of automobiles, it is desirable to convert the driving energy into solar cells, but since the energy density of sunlight is small, this A large area of solar panels is required to consolidate the solar panels. In order to attach this to the vehicle body without hindering the running performance, it is necessary to divide the solar panel into several parts and to have a mechanism that can take the most rational posture for receiving light and running. On the other hand, in order to prevent the weight of the vehicle body from being increased by attaching the solar panel to the body portion, a means for exerting air lift when the solar panel is running is required.

[0004]

[Means for Solving the Problems] In order to solve the above problems, the upper and lower two-stage wing cross-section substrates (3, 3 ′, 3 ″, ″ ′) are arranged in the body portion (2) of the vehicle body. , A solar panel membrane that converts sunlight energy into electric current on its upper surface (1)
Attached to the wing cross-section solar panel (4, 4 ',
4 ″, 4 ″ ′). This upper wing cross-section solar panel (4, 4 ′) is pin-coupled to the fuselage (2),
It is configured so that it can be rotated in the vertical direction, and can be rotated in the vertical direction according to the traveling environment (weather, day and night, traveling direction, etc.) so that the vehicle can travel in an optimal posture for receiving light and traveling. This wing cross-section solar panel (4, 4 ',
4 ", 4"') trailing edge, flap (down wing) (5,
5 ', 5 ", 5'")
These flaps (lower wings) (5, 5 ', 5 ", 5'") have an appropriate angle of attack (a, a ') (angle with the traveling direction, generally a, a'is about 15 to 20 degrees) ), The wing cross-section solar panel while running, to generate the same air lift as an airplane, so that the weight of the vehicle body can be reduced.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1, FIG. 2 and FIG.
It is a 40 scale drawing. In this embodiment, the size of the vehicle body is
Normal passenger car class (body length 4.5m, width 1.8m, height 2
m), and the wing cross-section solar panel (4, 4 ', 4 ",
4 ′ ″) is an effective light receiving area of about 12 m ₂ . The vehicle weight in this case is approximately 270 kg (including one passenger), and the air lift (lift) by the wing cross-section solar panel is approximately 80 kg at a normal running speed of 40 km, so the reduction rate of the vehicle weight is Almost 30%
It becomes a degree.

[0006]

EFFECT OF THE INVENTION The solar car of the present invention is a solar panel (4,4 ',
4 ", 4"') is configured to function both as a solar panel that converts sunlight into electric energy, and also as a function to reduce the weight of the vehicle by exerting air lift when driving. However, the solar panel (4, 4 ') of the upper stage wing section of the solar car of the present invention has a body part (2) at night and in cloudy weather. ) Is folded on both sides so that it can run in the same way as an ordinary electric vehicle, and its practicality is highly effective.
