Description

[Detailed description of the invention] This invention mainly relates to the mounting structure between the case of an in-vehicle instrument and a panel made of synthetic resin, etc., and is intended to prevent light from leaking through the gap between the panel and the case, and to prevent dust and other contaminants from entering the case. The purpose is to prevent this, and furthermore, to prevent the panel from lifting up.

Conventionally, molded products have been used for exterior parts such as cases and panels in order to reduce the weight of in-vehicle instruments.

Therefore, there is a drawback that the parts are deformed depending on the molding conditions during molding, the ambient temperature during use, etc., and gaps are generated.

The present invention has been devised in view of these points, and its contents will be explained below based on the illustrated embodiments.

Reference numeral 1 is a flat panel panel made of synthetic resin, and screw through holes 2 are bored in the corners.

Reference numeral 3 denotes a case body corresponding to the panel plate 1, which has a flange 4 around the opening and a protrusion 5 at the outer corner of the flange 4. Reference numeral 6 denotes a screw receiving hole provided in the flange portion 4, which is formed so as to coincide with the screw through hole 2 when the panel plates 1 are stacked on top of each other.

Reference numeral 7 denotes thick protrusions for forming the screw receiving holes 6, which are appropriately arranged.

8 is a set screw, 9 is a meter body housed in the case body 3, and 10 is a lamp.

Next, the operation of the present invention having the above configuration will be explained.

The panel plate 1 is placed on the flange 4 of the case body 3, and the set screw 8 is screwed into the screw through hole 2 and the screw receiving hole 6. Due to the tightening of the setscrew 8, the outer edge 11 of the panel plate 1 is in contact with the protrusion 5, so that the central part of the panel plate 1 is curved inward as shown by arrow A, and a part of the panel plate 1 is bent inward as shown by arrow A. It is pressed against the corner 12 of the section 4.

Therefore, it is possible to prevent an initial gap from being generated when the panel board 1 is superimposed on the case body 3 or a gap due to temperature deformation.

Therefore, the present invention has the structure and function as described above, and by applying stress to the panel board in advance and bending it, it is possible to forcibly anticipate the effects of molding defects and temperature deformation in advance. Correct it with
This has the effect of preventing gaps from forming, preventing light leakage, dust and other objects from entering through the gap between the panel and the case, and preventing the panel from lifting up.

Although the projections 5 are provided on the case body 3 in this embodiment, they may of course be provided on the panel board 1.

Claims (1)

[Claims for Utility Model Registration] (1) A protrusion 5 is provided on a part of the case body 3 or the panel plate 1, and the panel plate 1 is superimposed on the case body 3, and the protrusion 5 is fixed with a set screw 8 or the like. This is a panel mounting structure in which the center portion of the panel board 1 is curved inward by tightening the inside. (2) A panel mounting structure in which the protrusion 5 is disposed on the flange 4 of the case body 3 as described in the first claim of the utility model registration.
