Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an electronic component installation structure on a glass plate in which electronic components of various devices are installed on the surface of the glass plate.
[0002]
[Prior art]
In recent years, glass window breakage detection devices for theft prevention of automobiles, rain sensors for detecting raindrops accumulated on the surface of glass plates, and reception amplifiers for glass antennas provided on the surfaces of glass plates Etc. are attached (for example, refer to Patent Document 1). If it is a glass plate crack detection device, as shown in FIG. 4, the device 24 is attached to the concealing portion 22 (lower edge portion side of the belt line 23) of the front door glass 21 of the automobile via an adhesive layer. .
[0003]
Conventionally, as shown in FIG. 5 which is an example of a cross section taken along the line AA ′ of FIG. 4, an electronic component 27 including a printed board 26 on which an electronic component element 25 is mounted is resin. It was built in a lid 28 made of metal or metal, and was adhered to the glass plate 20 via an adhesive layer 29 such as an adhesive or adhesive double-sided tape. 6 is also an example of the AA ′ cross section of FIG. 4, and a fixing tool 30 for fixing the lid is fixed to the glass plate 20 in advance through an adhesive layer 31 such as an adhesive or adhesive double-sided tape. The lid 28 containing the electronic component 27 is engaged with and held by a lock mechanism 32 provided on the fixture 30. Moreover, when there is a metal part in the lid, there is a method (not shown) of fixing by soldering to a metal film fired on a glass plate.
[0004]

US Pat. No. 6,0055,527 (FIG. 2-8)
[0005]
[Problems to be solved by the invention]
However, in the structure in which the lid 28 is bonded to the glass plate 20 using an adhesive as shown in FIG. 5, it is necessary to pre-treat the bonding portion with a primer or the like in advance, and the adhesive is cured at the time of bonding. In the meantime, ultraviolet irradiation, heating / pressurizing treatment, etc. are required, which increases assembly time and man-hours, and costs. Even when an adhesive double-sided tape is used in place of the adhesive, heat and pressure treatment is required to obtain sufficient adhesive strength and durability between the lid 28 and the glass plate 20.
[0006]
Further, when the electronic component 27 built in the lid 28 breaks down for some reason, the lid 28 and the glass plate 20 are firmly bonded to each other. There was also.
[0007]
When the fixture 30 is installed on the glass plate 20, the maintainability is improved. However, in order to fix the fixture 30 to the glass plate 20, it is necessary to pass through an adhesive layer 31 such as an adhesive or an adhesive double-sided tape. An adhesive curing step by treatment, ultraviolet irradiation, heating / pressurization treatment is necessary, and the number of parts is increased, which is expensive.
[0008]
When recycling the glass plate 20, the lid 28 and the glass plate 20 are firmly bonded in the case of FIG. 5, and the fixture 30 and the glass plate 20 are firmly bonded in the case of FIG. 6. It was difficult to remove, and there was a problem in recyclability because debris such as adhesive and adhesive remained on the glass plate after removal.
[0009]
By the way, when electronic parts are installed on the window glass for automobiles, particularly when installed in a concealing portion of a door glass having an opening / closing mechanism such as the front door glass of FIG. And the electronic component installed on the glass plate is difficult to mount on the door glass unless it is thin.
[0010]
For this reason, in the case of a double-sided mounting base in which electronic circuits having complex functions are mounted on a substrate with a high density, the conventional structure for installing electronic components on a glass plate is thick, and interference with the door panel is a problem. there were. If the area of the substrate is enlarged and single-sided mounting is used, the thickness of the lid is reduced, but the line length of the electronic circuit is increased and the characteristics of the electronic component are degraded.
[0011]
SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide an electronic component installation structure on a glass plate without using an adhesive or the like and having a thin installation structure.
[0012]

It is possible to position a part of the electronic component on the inner side of the glass plate surface by disposing the electronic component, and it is possible to reduce the thickness of the electronic component installation structure on the glass plate.
[0015]
In addition to the opening hole and the insertion portion, it is preferable that the glass plate and the lid body have structures that fit or engage with each other.
[0016]
In other words, in addition to the fitting between the opening hole and the insertion portion, it has a mechanical coupling structure that fits or engages at least one of the glass plate and the lid with each other. Thus, it is possible to prevent the lid from vibrating or shifting, and it is possible to more firmly fix the lid on a predetermined surface of the glass plate without using an adhesive or an adhesive double-sided tape.
[0017]
For example, the fitting or engaging structure may be a structure in which a protrusion provided on the lid is fitted into a hole formed on a predetermined surface of the glass plate, or an edge of the glass plate And a holding mechanism for holding the elastic member at the end edge portion, and a structure for engaging the end portion with a biting mechanism that bites the end edge portion with a claw provided on the lid body. It is preferable to have a structure in which the insertion portion is pressed in the direction of the edge portion by elasticity.
[0018]
In addition, it is preferable that the lid body is waterproof, dustproof, and explosion-proof in order to protect electronic components from raindrops and the like.
[0019]
Moreover, it is preferable that the predetermined surface of the said glass plate suitable for implementation of this invention is a door panel concealment part located in the lower edge part of the door glass of a motor vehicle.
[0020]
Therefore, it is possible to provide an electronic component installation structure on a glass plate without using an adhesive or the like and having a thin installation structure.
[0021]
Further, in order to realize only thinning, an insertion portion is provided on the lid side, an opening hole is provided on the glass plate side, the structure for fitting or engaging is not provided, and the lid body and the glass plate are bonded with an adhesive or the like. It may be bonded via an adhesive layer to prevent the lid from vibrating or slipping.
[0022]

Since the body 2 is not dropped from the glass plate 1 and the projection 7 is fitted in the hole 4, the lid body is prevented from rotating or vibrating. 1 is firmly fixed on a predetermined surface.
[0025]
The inside of the lid body 2 forms a space sufficient to house the electronic component 27, and also has a storage space 8 inside the insertion portion. The electronic component 27 is built in the lid body 2 so that a part of the electronic component element 25 mounted on one side of the printed circuit board 26 fits in the storage space 8 of the insertion portion 5. The arrangement of the electronic component 27 is not limited to this, and most of the electronic component 27 may be arranged in the storage space 7 depending on the size and shape of the electronic component.
[0026]
As described above, by installing the lid body 2 including the electronic component 27 on the glass plate 1, the mechanical plate is used only on a predetermined surface of the glass plate without using an adhesive or an adhesive double-sided tape. An electronic component 27 can be installed. Further, by using the internal space of the insertion portion 5 of the lid 2 as the storage space 8 for the electronic component 27, when storing the printed board 26 on which the electronic component elements 25 are mounted on both sides, A part of the mounted electronic component element 25 can be arranged in the storage space 8 so that a part of the electronic component element 25 can be positioned on the inner side of the glass plate surface, so that the electronic component installation structure on the glass plate is made thinner. can do. Further, since the lid 2 is not bonded to the glass plate 1 with an adhesive or the like, the lid 2 can be easily detached from the glass plate 1 by releasing the return prevention mechanism of the distal end portion 6 of the insertion portion 5. It is possible and has a structure with excellent maintainability.
