Description

DETAILED DESCRIPTION OF THE INVENTION The tenth invention relates to the structure of a meter housing installed in an instrument panel of an automobile or the like.

For example, conventional automobile meter housing structures include those shown in FIGS. 1 and 211, for example.

In these 0HFCs, the symbol l is the instrument panel, 2 is the glass cluster, and 3 is the plastic-like meter housing.
is divided into a lower housing 3A and an upper housing 3B, and correspondingly, the cluster 2 is also divided into a lower cluster 2A and an upper cluster 2B.

7 langes 3a for lower housing 3Al'C bolts
m is provided, and correspondingly an upper housing 5II is provided.
K % 171 attaching 7 twist @sb is provided, upper housing 310 @ end Ka meter cover 4
7 twisters @8c are provided for installation. The meter cover 4 is made of transparent acrylic resin. 7 langes for assembling the upper housing 3BKTh sbo
There is a forest near the installation site, and an overhanging ink wall facing inward. This protruding part 6 is for hiding the peripheral terminal part of the meter dial, which will be described later, from the outside.Because this protruding part 5 is provided, the ten-hour housing 3A and the upper housing 3B are integrated in advance. If the meter housing 3 is molded, it will not be possible to attach the meter 6 to the lower housing 3A.
and an upper housing 3B.

On the other hand, lower cluster 2A and upper cluster 2
B is provided with a plurality of claws 2a and ffb as assembly means, respectively.

and the cluster 2 is on the instrument panel I.
Fit 4 with 2 K nails! After the lower cluster 2A Ks meter 6 is attached, the lower housing 3A is fixed with screws through the screw 7. Then, the meter cover 4 is attached with the screw 7 to the upper nozzle.・Fix the housing 3B with the lower housing 3AK screws 8. 11. Upper housing 3B is installed. So O extrusion part 5 simeter character 1116m,
The 6m'0 scrap side terminal is hidden to maintain balance. 6b
, 6b' are guidelines. Next, the upper cluster 2B covers the upper housing 3B, and the assembly of the cluster 2 that covers the meter housing 3 to the lower cluster 2AK fitting panel 1 is completed using the claws 2b.

However, in such a conventional meter housing structure, the meter housing 3 is divided into a lower housing 3A and an upper housing 3B, and the cluster 2 is divided into a lower cluster 2A and an upper cluster 2B. The base member was assembled using screws 7, 6 and claws 2m, 2b, etc. However, the number of parts is large, which increases the number of assembly steps and increases costs. . In addition, since there were a large number of parts, there was a problem in that eight degrees of assembly was not enough.

The present invention has been made by focusing on such conventional problems, and includes a ninth structure in which the lower housing and the lower cluster are integrated, and a second structure in which the upper housing and the upper cluster are integrated. The opposing peripheral edges of the first and second structures are integrally molded with a thin hinge that connects them, and the lower housing and the upper housing, and the lower cluster and the upper cluster are assembled by folding them into pairs using this thin hinge as a bending fulcrum. The aim is to solve the above problems by providing assistance.

below. Jin's invention will be explained based on Figure ilK.

FIG. 3 to FIG. 6 are diagrams showing an embodiment of the present invention.

In FIGS. 3 to 6, parts that are the same as or equivalent to those shown in FIG. 3 and FIG.

First, to explain the structure, in the first 1ji of the 6th
As shown in the figure, the lower housing 3A and the lower cluster 2A are integrated to form a first structure 9m, while the upper housing 3B and the upper cluster 2B are integrated to form a second structure 9B. For example, the first structure 9A and the second structure 9B are jlI3sl! They are connected by a thin hinge IOK at the opposing peripheral edges on the lower side. The first structure 9A and the second structure 9B connected by the thin-walled hinge 10 are integrally molded in the same molding process 11. And lower housing 3A in GT structure 9AK
A T-shaped image stop portion 11m is simultaneously molded at the portion. A nine-shaped locking portion 11b is formed on the instrument panel l, corresponding to Hiroko's T-shaped locking portion 111. The claw on the second structure 9B side is on the first structure 9A! b...moat hole 2
c... is drilled. 2d is a hole for screw attachment.

on the other hand. *2 The structure 9BK has a stepped portion 3d for attaching the meter cover 411IL. The meter cover 4 is provided with claws 4I for mounting, and a step 3dK expansion mounting hole 3@ is drilled correspondingly thereto. The meter cover 4 is fitted and fixed to the stepped portion 3d by a claw 4aK via a seal n.

Next, the assembly and operation will be explained.

First, the meter 6 is attached to the lower housing 8A of the first structure 9AK. Next, using the thin hinge 10 as a bending fulcrum, the first body structure 9A and the second body body PB are mutually rotated and bent in opposite directions, and the claws 2b are inserted into the fitting holes 2c.
・Insert into. The lower housing 3A and the upper housing 3B are formed by the subsequent steps of turning and folding and fitting and fixing the claws 2b.

Then, the lower cluster 2A and the upper cluster 2B are brought into contact with each other, and the meter housing and the cluster are assembled. At this time, the first structure 9A and the second structure 9B
Since the lid is integrally molded with a molded lid having a predetermined size, assembly with predetermined matching dimensions is possible. Incidentally, when assembling, a sealing port is sometimes provided between the lower housing 3A and the upper housing 3B at their opposing parts.

To assemble, slide the rear KST type engaging part stopping part m into the groove shaped stopping part @llb, and then tighten the lower part in Fig. 3 on the opposite side from this fitted part with the screw 14 to complete the assembled body. ) to instrument panel 1). This is a working hole for attaching the IJSFi screw 14.

As described in detail above, according to the present invention, the four-wheel 1 structure and the second structure that integrates the upper housing and the upper cluster are connected by a thin hinge that connects the opposing peripheral edges of the 111111 structure and the second structure. The lower housing and upper housing, as well as the lower cluster and upper cluster, are assembled by folding them in contact with each other, using this thin hinge as a bending fulcrum, so the number of parts is small.) The effect is that the number of man-hours is reduced, assembly work becomes easier, and costs can be reduced. The 1st structure and the 2nd structure are integrally molded by a thin-walled hinge according to the predetermined dimension orit type 11, which improves the dimensional accuracy of assembly and further increases the rigidity of the assembled structure. The effect of doing so can be obtained.
