Description

[Detailed Description of the Invention] This invention relates to a solar cell mounting structure for automobiles.

The conventional solar cell mounting structure for automobiles is
For example, there are those shown in FIGS. 1 to 3 (see Japanese Utility Model Application No. 16512/1983). The solar cell 1 for an automobile needs to be installed in a part of the car body 2 that can sufficiently absorb solar energy, and in this conventional example, the roof panel 3 itself, which is the outer panel of the car body, is recessed and the solar cell 1 for the car is installed there. Thickness of solar cell 1,
Either a concave solar cell mounting part 4 (hereinafter simply referred to as the mounting part) with a size corresponding to the vertical and horizontal sizes is formed [Fig. 2], or an opening is provided in the roof panel 3 and a dish-shaped hole is formed below the opening. A concave mounting portion 6 is formed there by attaching another bent member 5 and welding its periphery (Fig. 3), and the solar cell 1 is placed within these mounting portions 4 and 6. The mounting bracket 7 of the solar cell 1 and the bottom surface 8 of the mounting parts 4 and 6 are fixed with weld bolts 9. Furthermore, weather strips 11 and 12 for sealing are provided in the gap 10 around the solar cell 1. 13 is a nut, 14 is a harness, 15 is a grommet for taking out the harness, and 16 is a headlining.

However, in such a conventional solar cell mounting structure for automobiles, since the mounting bracket 7 of the solar cell 1 is directly fixed to the mounting parts 4 and 6 with weld bolts 9, vibrations of the vehicle body 2 are prevented. This is likely to be transmitted directly to the solar cell 1, and the elements (wafers) of the solar cell 1 may be damaged.

This idea was created by focusing on the conventional solar cell mounting structure for automobiles, and by taking advantage of the fact that sealing weather strips are usually made of rubber material, this weather strip was developed. It is an object of the present invention to provide a solar cell mounting structure for an automobile in which at least a portion of the lip is provided with an extension portion and used as a so-called cushioning material to prevent vibrations of the vehicle body from being directly transmitted to the solar cell. .

This invention will be explained below based on the drawings.

FIGS. 4 and 5 are diagrams showing an embodiment of this invention. In the following description, parts that are the same as or similar to those in the prior art will be designated by the same reference numerals and redundant explanation will be omitted. Numerals 20 and 21 are weather strips for sealing, and are provided with an extending portion 22 that extends downward. The weather strips 20 and 21 are provided in the gap 10 around the solar cell 1 as described in the conventional example, and are therefore attached so as to surround the entire circumference of the solar cell 1, but the extension portion 22 is at least It suffices if it is formed in a part of it. The extending portion 22 is used as a so-called buffer material, and is interposed between the mounting bracket 7 and the bottom surface 8 of the mounting portions 4 and 6. In addition, 23 in the figure is another weather strip for the cap.

Next, the mounting state of the solar cell 1 will be explained.

When placing the solar cell 1 in the mounting parts 4 and 6, the weather strips 20 and 21 for sealing are positioned in advance and the extending parts 22 of the weather strips are placed between the mounting bracket 7 and the bottom surface 8 of the mounting parts 4 and 6. A nut 13 is screwed into the part of the weld bolt 9 which is interposed between the weld bolts 9 and protrudes upward from the mounting bracket 7, and another weather strip 23 for the cap is fitted into the space above the nut 13 for sealing. be.

FIG. 6 shows another embodiment of this invention. In this embodiment, the extension portion 22 explained in the previous embodiment is only interposed between the mounting bracket 7 and the bottom surface 8 of the mounting portions 4 and 6; The portion 24 includes an upper lip portion 24a that can be interposed between the nut 13 on the upper surface side of the mounting bracket 7, and a lower lip portion 24b that can be interposed between the lower lip portion 24b and the bottom surface 8 on the lower surface side of the mounting bracket 7. . Therefore, when installing the solar cell 1, upper lip portions 24a,
The lower lip portions 24b are positioned respectively,
Extension part 2 including upper and lower lip parts 24a and 24b
4 is designed to exhibit a better buffering function than the extension portion 22 described above.

FIG. 7 shows yet another embodiment of this invention. In this embodiment, the bottom surface 8 of the mounting parts 4 and 6 and the solar cell 1
By using the space 26 created between the bottom surface 1a of the vehicle body 2 and the roof drip part 2 of the vehicle body 2,
7 is connected with a drain hose 28. According to this embodiment, the sealing weather strip 1
1, 12, 20, and 21, in the event that rainwater enters from the gap 10 around the solar cell 1, it is immediately removed from the mounting portion 4 through the drain hose 28.
6. Specifically, the liquid is discharged from the space 26. In addition, in order to discharge efficiently, the mounting part 4,
An inclined portion 29 may be provided on the bottom surface 8 of 6.

As explained above, according to this idea,
Providing an extension part on at least a part of a weather strip for sealing provided in a gap around the solar cell,
This extended section is interposed between the solar cell mounting bracket and the bottom of the solar cell mounting section on which the solar cell is placed, and is fixed with bolts, so vehicle body vibrations are not directly transmitted to the solar cell, and weather Since the extended portion of the strip acts as a rubber cushioning material and alleviates vibrations of the vehicle body, it has the effect of improving the durability of the solar cell element. Furthermore, according to the embodiment shown in FIG. 6, an extending portion is provided not only between the mounting bracket of the solar cell and the bottom surface of the solar cell mounting portion, but also between the top surface of the mounting bracket and the nut screwed into the bolt. Since it is interposed, vehicle body vibration can be alleviated even more efficiently. Furthermore, according to the embodiment shown in FIG. 7, even if rainwater should infiltrate beyond the weather strip provided around the solar cells, it can be quickly drained and the rainwater will not accumulate on the bottom of the solar cell mounting part. In addition to the above-mentioned common effects, it is also possible to prevent functional damage to solar cells and corrosion of vehicle bodies.
