Description

An adjustable roof solar power generation device

technical field

The invention relates to the technical field of using solar energy to generate electricity for vehicles, in particular to an adjustable roof solar power generation device.

Background technique

With the development of new energy vehicles, there are higher requirements for the charging method of the car battery and the wind resistance. The traditional fast charging and charging pile charging cannot cope with extreme environments; for example, the vehicle is in a desert or grassland environment; In the middle, with the arrival of the peak power consumption, the charging station will have the risk of limited power.

Therefore, using solar panels to supplement the electricity of vehicles is an economical, convenient and pollution-free new way, which is worthy of vigorous promotion. A solar cell is a device that uses natural light sources for energy conversion, and its own conversion rate has high requirements for the illuminated area and irradiation time.

Judging from the existing concept cars and other inventions, most of the structures cannot meet the irradiation area and the lighting time at the same time, which will cause the charging efficiency to be too low, resulting in a waste of time. Force and vehicle speed control the expansion area of the solar panel, which affects the wind resistance and wastes the power source; in order to ensure that the vehicle uses the solar panel to charge the vehicle, the absorption coefficient of the solar battery can be increased to the greatest extent reasonably and the design wind resistance value can be maintained.

Through observation and conclusion, it is known that the current solar vehicles generally have the following problems:

One: the unit area exposed to the sun by the vehicle is insufficient. At present, most concept vehicles just install a solar panel on the roof, which will cause insufficient light area and low absorption coefficient of solar cells, resulting in waste.

Two: the vehicle is exposed to insufficient sunlight. As the sun moves, the solar panel cannot rotate, so that the illuminated area is gradually reduced, resulting in a gradual decrease in the solar absorption coefficient, resulting in a waste of time.

Third: During the driving process, the vehicle can manage the protruding area of the solar panel by sensing the wind speed and the remaining power of the battery, so as to minimize the impact on wind resistance.

Therefore, how to effectively solve the three existing problems is a topic being studied now.

Detailed ways

The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

In a specific embodiment of this solution, an adjustable roof solar power generation device is provided, by fixing the device provided by this solution on the roof of the vehicle, using the solar panels therein to supplement the electricity of the vehicle, and then Reach the situation of improving charging efficiency and coping with extreme charging environments.

In current existing vehicle charging devices, the following problems generally exist:

One: the unit area exposed to the sun by the vehicle is insufficient. At present, most concept vehicles just install a solar panel on the roof, which will cause insufficient light area and low absorption coefficient of solar cells, resulting in waste.

Two: the vehicle is exposed to insufficient sunlight. As the sun moves, the solar panel cannot rotate, so that the illuminated area is gradually reduced, resulting in a gradual decrease in the solar absorption coefficient, resulting in a waste of time.

Third: During the driving process, the vehicle can manage the protruding area of the solar panel by sensing the wind speed and the remaining power of the battery, so as to minimize the impact of wind resistance

Aiming at these three problems currently existing, this plan specially designs a solar power generation device that can solve the above problems; specifically, in the specific embodiment of this plan, see Figure 1-Figure 6, the solar power generation device includes a first solar power Panel 101; here the first solar panel 101 is fixed on the top of the vehicle; the first solar panel 101 is fixed to the top of the vehicle as a main solar energy absorbing structure to ensure that solar energy can be effectively converted into electrical energy.

It should be noted that the first solar panel 101 is generally a large panel structure. In the traditional design, the first solar panel 101 completely covers the roof of the vehicle, but in some current models, there are sunroof structures on the roof. ; Therefore at this time, the first solar panel 101 is completely covered with the roof of the whole vehicle, which will affect the normal opening of the sunroof; therefore in this program, the first solar panel 101 of design should at first avoid the sunroof. Influence.

Preferably, in a specific embodiment of this solution, the coverage area of the first solar panel 101 is 2/3 of the roof of the vehicle; that is, as long as most of the roof can be covered, effective light energy conversion can be performed. , which can meet the design requirements of this scheme.

In this scheme, in order to be able to effectively control the effective area of the solar panel being illuminated, the scheme of the solar panel group is also proposed here; specifically, the solar panel group here specifically includes the second solar panel group 200 and the second solar panel group 200 with the same structure. For the three solar panel groups 300, it can be understood that the second solar panel group 200 and the third solar panel group 300 in this solution are only different in the arrangement positions, and the specific composition structures of the two solar panel groups are the same.

The difference between the two solar panel groups (the second solar panel group 200 and the third solar panel group 300) is reflected in the position of the layout; specifically, the second solar panel group 200 and the third solar panel group 300 are located on the top of the vehicle; the second solar panel group 200 and the third solar panel group 300 perform telescopic movement in opposite directions relative to the first solar panel 101; the second solar panel group 200 and the third solar panel group 300 are in an unfolded state when they are stretched out, and they are in a contracted state when the second solar panel group 200 and the third solar panel group 300 are retracted.

It can be understood that the two solar panel groups (the second solar panel group 200 and the third solar panel group 300) have telescopic adjustment functions, and under certain working conditions, the second solar panel group 200 and the third solar panel group 300 can Compared with the first solar panel 101, after unfolding, the area of the entire solar panel is increased, so that the effective area of illumination is significantly increased, which greatly promotes the conversion of light energy to electrical energy; In the working condition, the second solar panel group 200 and the third solar panel group 300 can be shrunk relative to the first solar panel 101, preferably, the second solar panel group 200 and the third solar panel group 300 will be shrunk as a whole Below the first solar panel 101, this will make the appearance of the entire vehicle more concise, especially in the process of driving the vehicle, which will greatly promote the reduction of driving resistance.

Further, as a preferred improvement of the present invention, in an adjustable roof solar power generation device provided by the present invention, the second solar panel group 200 includes a first solar panel group 200 arranged on the left side of the first solar panel 101 Two solar panels 201 ; the third solar panel group 300 also includes a third solar panel 301 arranged on the right side of the first solar panel 101 .

Considering cost-effectiveness, thin-film photovoltaic cells are adopted and used in the second and third generation solar photovoltaic power generation technologies. The principle of power generation of thin-film cells is similar to that of crystalline silicon. When sunlight shines on the cell, the cell absorbs light energy to generate photogenerated electron-hole pairs. Under the action of the built-in electric field of the cell, the photogenerated electrons and holes are separated, and the holes drift. To the P side, the electrons drift to the N side, forming a photoelectromotive force, and when the external circuit is connected, a current is generated. Compared with traditional solar panels, this type of battery is low in cost, small in size, light in weight, easy to carry (thickness can reach 5mm), and its own weight will not affect the quality of the vehicle. At the same time, because of the characteristics of the thin-film battery panel, it is not easy to fall off during the process of unfolding or storing, and there is no harm to vehicles and personnel.

The small board is stored between the side wall and the roof when not in use, and stretches out when in use, which can increase the absorption area. In order to better carry, stretch, and rotate, the overall structure should be simple, the weight should be light, and the thickness should be kept at about 3.5mm.
