Description

The present invention relates to a cooling device for an automobile using an in-vehicle solar cell panel, which can lower the in-vehicle temperature when the automobile is parked under high temperature and exposure to sunlight.
In particular, it relates to structural improvements inside automobiles, where the ceiling inside the car is doubled, and a base with two sets of retractable solar panels installed in the double layer is stored and installed. It is.
By pulling down the base with the solar cell panel to the inside of the front and rear glass, solar energy can be absorbed, and the solar energy can be converted into electric energy to activate the automobile cooling device.
Therefore, when the car is parked under high temperature and exposure to sunlight, the interior of the car can still be kept at a low temperature and comfortable, and it will not affect any structure and function of the original car, which is the present invention. It is the feature.

As is well known, the car interior equipment of each company in the market is extravagant and has many functions, but when the car is parked under high temperature and exposure to sunlight, it becomes sultry due to the inside of the car being sealed. There is generally no way to improve the phenomenon of high temperatures, and when people get on and drive again, they all feel extremely discomfort and scorching heat.
And after starting a car and applying air conditioning strongly, after driving for a comparatively long time, the effect that the temperature in a car finally falls can be acquired.
In addition, gasoline is wasted, and interiors and decorations inside the vehicle are always damaged by high temperatures and direct sunlight, causing discoloration and generating toxic gas to the human body.
This phenomenon has been experienced by all car riders and is believed to be even more severe, especially in Southeast Asia and Africa.

  To summarize the above, the automobile is striving for perfection in the current technology, but there is no way to improve the above phenomenon, the function of the automobile is still not complete, and there is room for improvement.

As mentioned above, the various automobiles in the current market generally have no way of overcoming the sultry and high temperatures caused by the car being sealed when the car is parked under high temperature and exposure to sunlight. , It makes you feel the heat and endurance that burns when people get on and drive again.
As people are now demanding improved quality for their private cars, with the development of current scientific knowledge and materials, this problem can already be improved and overcome.

The present invention is based on the utility model law, is a creation of a technical idea utilizing the laws of nature, and corresponds to a device related to the shape, structure or combination of articles.
A cooling device using an in-vehicle solar panel of an automobile according to the present invention has a double layer installed on the ceiling inside the automobile, and two sets of solar panels that can be pulled down and / or folded inside are attached. The foundation can be stored and attached.
The two sets of foundations are composed of foundations on which solar cell panels can be installed, and may be composed of, for example, a series of rectangular boxes having many concave portions, and the boxes are connected to each other by fasteners. It may be.

Both ends of the box have a rotatable shaft that can be rolled in multiple directions and a shaft recovery spring, and the shaft is further connected to a bearing and is movably installed on the rail by the bearing. It is.
For example, each box has a rotatable shaft at both ends and a shaft recovery spring that adjusts the amount of expansion and contraction in the longitudinal direction. A bearing is connected to the other end of the shaft and the bearing is It is fitted on the rail.
Therefore, the base can be easily bent and moved along the rail, and can move, for example, in a manner similar to the function of a general shutter.
A hard or soft solar cell panel (Solar Cell) can be mounted on the box.

Rails will be installed on both sides of the double layer of the ceiling, and the base with the solar panel attached will be moved and pulled out.
Rails can also be installed on conventional pillars on the left and right sides of the front and rear windows in the car, and are connected to the rails on both sides in the double layer of the ceiling.
The foundation with the solar panel attached can be easily pulled down from the double layer of the ceiling along the rails on the left and right glass columns, covering the inside of the front and rear glass.
In this case, the installation angle of the rails arranged on the left and right columns of the glass can be changed to any angle as necessary, and the optimum angle corresponding to the sun's inclination angle according to the season etc. The angle of the rail can be arbitrarily determined so that the base can be located.
Alternatively, the base itself and / or the surface of the solar cell panel can be inclined at an arbitrary inclination angle, and sunlight can be efficiently absorbed.
By constructing as described above, solar energy under high temperature and exposure to sunlight is absorbed, and electric energy is generated through, for example, a current transformer / converter.

Furthermore, this electric energy drives an energy-saving cooling device for a spiral (scroll) compressor that is driven by an energy-saving and DC brushless converter motor installed at an appropriate position in the vehicle body.
In this way, hot air inside the vehicle is circulated and cooled, and the interior of the vehicle is kept cool and comfortable.

A solar panel that can be folded up and down, can be safely stored in the double layer of the ceiling inside the car, maintains the aesthetics of the car, and is not damaged by external forces such as the weather, such as rain, wind or dust. The mounted base covers the front and rear glass, activates the cooling device with electric energy generated when parking under high temperatures exposed to the sun, does not affect the function of the original car, and does not consume gasoline The greatest feature of the present invention is that it does not pollute the environment.
Therefore, it is completely different from a conventional solar car in which a solar cell panel is attached outside the vehicle.

Solar energy is infinite and not only does it not pollute the environment, but it does not cost anything.
Furthermore, the solar cell panel has a long life, and the stronger the sun's sunlight, the greater the amount of power generation and the better the cooling effect.
By lowering the solar cell panel to the inside of the front and rear glass, it also produces the effect of generating heat and simultaneously insulating the interior of the vehicle from the outside.
That is, it has a heat insulating effect by covering the window portion and blocking the irradiation of sunlight into the vehicle.

Furthermore, when driving for a long time under high temperature and exposure to sunlight, for example, on highways or in heavy traffic jams, lower the front and rear solar panels to an appropriate position so as not to obstruct the driver's view. be able to.
Then, by absorbing solar energy and starting the device of the present invention, the cooling effect in the vehicle can be improved, and the effect of reducing the burden of compression cooling using a conventional engine and gasoline is also brought about.

Embodiment of invention

Embodiments will be described below with reference to the accompanying drawings.
As shown in FIG. 1, a double layer 1 is installed on the ceiling of a vehicle, and a set of bases 4 each having a solar cell panel mounted therein is installed in the front and rear.
In this case, the solar cell panel has a recess in the base, and even if the solar cell panel is configured to be fitted in the recess, or is placed on the base, or the solar cell panel is mounted on the base with a locking tool. It may be a thing.
Furthermore, the solar cell panel in the present invention is not limited to a single panel-like one, and may use one or a plurality of solar cells, or has a solar cell module at a necessary place and has sunlight. As long as it has a solar cell condensing part having a part capable of condensing light.
Therefore, regardless of whether the shape is a specific shape such as a plane shape, a solid shape or a sheet shape, a shape such as a thick or thin shape, or a specific size, for example, a single cell or an aggregate of cells, all the solar It shall correspond to the battery panel.
Next, the set of bases 4 respectively in the front and rear is a set of bases 4 to be pulled down in the respective directions of the front and rear glass of the automobile, and an electric wire that expands and contracts is accommodated between the two sets of bases. By providing the box 8, the two sets of bases 4 can be installed in a separable manner.
Rails 2 and 3 are installed in the vehicle inside the conventional support column on the left and right of the windshield and rear glass, and the rails 2 and 3 continue to the double layer 1 of the ceiling.

The base 4 to which two sets of solar panels are attached is composed of a series of concave rectangular boxes having a suitable length, and a solar panel 5 (Solar Cell) is installed on the boxes.
Since the boxes are connected to each other by a fastener 9 in the configuration shown in the figure as an example, the base 4 can be bent and can move like a general shutter function.
At both ends of each box, there are a shaft 21, a shaft restoration spring 22 and a bearing 10 that can be rolled in multiple directions.
That is, as shown in FIG. 4, each box has a rotatable shaft 21 at each end and a shaft restoration spring 22 for adjusting the length of the shaft 21 in the longitudinal direction. It is supported by the bearing 10.
In this case, the shaft 21 is continuously connected to the bearing 10. For example, the shaft 21 may be pivotally supported, or the bearing 10 may function as a universal joint.

For example, a spherical bearing may be used as the bearing 10 and the shaft 21 may be pivotally supported on the bearing.
By configuring in this way, the shaft 21 can be rotatably installed, and the base 4 can be moved along the rails 2 and 3.
In this case, the bearing 10 is fitted in the grooves of the rails 2 and 3 and is movable along the rails 2 and 3.
That is, the rails 2 and 3 have groove portions, and grooves are formed along the longitudinal direction of the arranged rails 2 and 3, and the bearing 10 is movably fitted in the grooves. It can be worn.
Therefore, for example, by inserting a spherical bearing into a groove along the rail, the inside of the groove can be movably installed.
In addition, for example, the rail may be formed by protruding flanges on both sides and mounting a bearing in a groove formed between the flanges, or the flange may be further bent in the groove direction to form a cavity. The hollow portion may be formed and used as a groove.
Also, the bearing 10 is shown as an example of a spherical shape, but is not limited to this shape, as long as at least the shaft 21 is rotatably connected, and can be mounted so as to be movable along the rails 2 and 3. Well, in addition to the one fitted in the groove, it can be installed movably along the rails 2 and 3 without having a groove, for example, one having a locking part or a locking structure that can be moved to the rail and can be continuously connected to the bearing 10, Or you may have a mounting part which can mount | wear the rail 10 with the bearing 10 movably.

Next, in the configuration shown in FIG. 1, the base 4 to which the solar cell panel is attached is such that each bearing 10 is connected to a shaft 21 fitted in the groove of the rails 2 and 3. It moves along the rails on the right and left columns of the windshield and rear glass along the groove in which the bearing 10 formed in 2 and 3 is fitted.
Furthermore, it has a brush 7 for cleaning the solar cell panel, and can be easily raised and lowered through the brush 7 to enable cleaning of the light receiving surface of the solar cell panel.
As shown in FIG. 4, the shaft 21 that is rotatably connected to the bearing 10 can be freely expanded and contracted along the longitudinal direction of the shaft by a shaft recovery spring 22 in a pipe formed on the base 4. .
Further, the bearing 10 connected to the shaft 21 is elastically pressed in the directions of the rails 2 and 3 by the shaft recovery spring 22.
And the base 4 to which the solar cell panel is attached by this expansion and contraction has different widths between the right and left columns of the glass, that is, all the widths corresponding to the glass surface of the automobile which becomes narrower at the upper part of the glass surface and becomes wider toward the lower part. Can be raised and lowered freely.

FIG. 2 is a schematic view showing a state in which the entire width of the glass surface of such a widening automobile can be covered and can be raised and lowered freely, and particularly lowered.
As shown in the figure, for example, a handle 11 may be attached in the middle of the base 4 to which the solar cell panel is attached for the convenience of raising and lowering operations.
Or you may have a handle, a knob part, etc. which were provided in other places.
Further, it may have a mechanism for automatically raising and lowering by an electrically known method.
In addition to electric power, the base 4 on which the solar panel is mounted can be automatically moved along the rails 2 and 3 by driving the motor using air pressure or other power source or by driving the compressor. It may be.
Of course, it may of course have a control mechanism that can stop at an arbitrary position on the rail, or can automatically control the raising and lowering when necessary.

FIG. 3 is a diagram simply showing the structure of the cooling device. As shown in FIG. 1, the cooling device 6 is installed at an appropriate position in the vehicle body.
In such a case, as shown in FIG. 3, the solar energy of the solar panel 20 is passed through the current transformer / transformer 19 and the converter type motor 16 without the DC brush is started to form a spiral type (scroll type) compressor. It can also be configured to start 17 as well.
In such a case, a solar panel 20 shown in FIG. 3 shows an example of an assembly of cells or modules as a solar battery panel, and shows a system for condensing light.
Therefore, the solar cell panel to be mounted on the base may be the above-described solar cell module, may be grasped as a solar cell, or may be in a panel shape, and at least the solar cell panel described above. If it is.
Next, the refrigerant made from the refrigerant enters the heat exchange pipes 14 and then enters the air conditioning coils 18 and returns to the compressor 17 again.
In addition, the high-speed exhaust / absorption fan 15 absorbs hot air, which enters the heat exchange pipes 14 through the pipe 12 and is discharged from the outlet 13 after the hot air is cooled. It has the effect of lowering the temperature inside the vehicle exposed to high temperatures and sunlight.

The present invention is technically feasible in each of the above states, but can be advantageously carried out particularly under the following conditions.
Refrigerators powered by the power generated by solar panels are already in use on African portable vaccine refrigerators.
And solar energy power is already widely used in the power source of high power consumption water absorption pump (no intermediate storage battery is required) and water circulation pump of swimming pool in remote power-free area.
Therefore, it is sufficiently feasible by using the function as a cooling device of the cooling device using the solar cell panel inside the automobile according to the present invention.
Alternatively, it can be used in such a cooling device.

Solar panel production costs have been decreasing each year, and the efficiency of power generation (PTC) has reached 35%, continuing to increase every year.
The cost of the cooling device using the solar cell panel in the vehicle of the present invention is small and does not greatly affect the production cost of the vehicle.
In addition, thin, large solar panels that can be rolled (eg CIS Thin Film) can already be produced and can be an alternative to common rigid solar panels (eg Mono Crystal Type). This is another option, and there is a feasibility on the effect of the present invention.

Since the device of the present invention is an independent facility, it does not affect the position and function of the existing equipment in the car, that is, the rearview mirror, sun visor, and safety handle, and also affects the overall weight and structure of the car. Absent.
The base with the solar panel attached can be stored in the ceiling when not in use, so that the aesthetics of the car can be maintained and the driver's view is not obstructed.
In addition, when it is used while being pulled down, it is not damaged by external influences such as external forces, such as weather, is not exhausted by gasoline, is friendly to the environment, is more durable and can be used for a long time. There is a useful feasibility.
The cooling device of the present invention adopts the latest energy-saving DCBrushless converter type motor that requires no maintenance and the latest energy-saving spiral type (scrolling) compressor. Since the converter motor continuously operates the compressor without interruption, it has a useful feasibility of saving energy, reducing the compression ratio of the compressor, and maintaining continuous cooling in the vehicle.

Solar energy, for example, directly drives the cooling device via a current transformer / converter without using an intermediate storage battery, reducing power loss and reducing the cost of the device. It can be used more efficiently.
Of course, a battery may be used.
The foundation to which the solar panel of the present invention is attached can be installed at an angle by lowering along the rails installed in the car inside the conventional column on the left and right of the front and rear glass, for example, necessary Depending on the angle, the angle can be lowered to about 35 degrees, which is the most suitable angle for absorption of solar energy in the summer in this region.
In addition, since the angle at which solar energy is efficiently absorbed varies depending on the region, season, and the like, a solar cell panel or rail that can adjust the angle can be designed, and solar energy can be efficiently absorbed.
For example, the rail installed in the vehicle inside the left and right columns of the front and / or rear glass may be capable of changing the inclination angle of the rail to an arbitrary angle.
For example, there is a shaft part that can be tilted at an arbitrary position in one end direction of the rail, and a member that can be fixed at an arbitrary position by moving the rail position in the other end direction, thereby changing the tilt angle in the rail arrangement state. It may have a structure capable of
In addition, the base and / or the surface of the solar cell panel to which the solar cell panel connected to the rail is attached may be changed to an arbitrary inclination angle with respect to the rail.
As a result, the condensing surface of the solar cell panel attached to the base can be directed in an arbitrary direction, and the surface can be directed so that the most concentrated sunlight is directed in a direction perpendicular to the efficient sun. it can.
