Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an instrument mounting structure that allows easy installation and removal of instruments from a support wall.

Conventionally, the structure for attaching instruments to the instrument panel was
The one shown in the figure is the most common.

That is, this figure shows an example in which various instruments are attached to an instrument panel of an automobile, and in particular, an instrument 1 is illustrated in which a housing 2 and a hood 3 are integrally formed.

An opening 5 for installing a meter is provided on the front side of the instrument panel 4, and the instrument 1 is inserted into the opening 5, and the upper and lower parts of the hood 3 are attached to the instrument panel 4 using tapping screws 6 and 7. It is installed.

At this time, in order to prevent the tapping screws 6 and 7 from being directly visible to the occupants, the upper screw 6 should be fixed from below, the lower screw 7 should be fixed from the front, and a decorative plate 8 or the like should be used to cover the eyes. We are trying to come up with the following.

9 is a pad, 10 is a spring nut screwed into the tapping screws 6 and 7, and 11 is a connector for multi-pole connection, which is fitted after the instrument is installed.

However, in this conventional structure, the tapping screw,
There are many parts such as spring nuts, decorative plates, etc., and there are problems in that it is difficult to align the screws and nuts, and it is difficult to screw in the screws.Furthermore, the instrument is supported only by these screws. Therefore, the support for the rear end of the instrument was not sufficient, and there were drawbacks such as the instrument vibrating, impairing its meter function, and the vibration causing the screw to loosen and causing the instrument to fall off the instrument panel.

In view of the above, the present invention has a configuration in which an instrument is fitted into a recess formed in an instrument panel, in which a support section is provided on the bottom surface of the instrument and the four locations, a lock section is provided on the upper surface of the front end, and a locking section is provided on the lower surface of the instrument panel. This makes it easy to attach and remove the instrument, and prevents it from falling off.Furthermore, the addition of a guide part and pressure contact part makes it easier to fit the instrument, and the support is more secure. The purpose is to provide a mounting structure that can be used to

Hereinafter, the present invention will be explained using an example in which the present invention is applied to an automobile instrument panel.

In Figure 2.3, 20 is the instrument panel 2
1 and a pad 22 that covers the surface of this panel.

The instrument panel 21 has a sideways container shape that allows the instrument 23 to be fitted through its opening at the instrument mounting position.
In addition, a recess 24 is formed in which the ten faces 29 are slightly inclined downward so as to become narrower toward the back.

On the bottom surface 25 of this recess 24 for instrument sliding, there is a guide protrusion 2 extending in the direction of insertion of the instrument and shown in cross section in FIG.
6 is integrally formed at approximately the center position.

In addition, there are locking holes 2 at the left and right positions of the front end (opening) of the bottom surface 25.
7 and 27, and the bottom edges 28 and 28 facing the locking holes 27 and 27 have tapered lower edges.

On the other hand, tongue-shaped engagement members 30 are notched at the left and right positions of the front end of the upper surface 29 at four locations so as to protrude toward the back.
The retaining member 30.30 is provided with downwardly protruding protrusions 31, 31 at an intermediate position thereof, and operating portions 32, 32 formed thickly at the tips thereof.

Furthermore, a hole 34 is formed approximately in the center of the inner surface 33 of the recess, and a connector 36 to which a harness 35 is connected is attached.

On the other hand, the instrument 23 has a hood 38 integrally formed with the housing 37, which protrudes forward beyond the front glass 37a of the instrument incorporated into the housing 37. In particular, the upper surface of the hood 38 is provided with an allowance. There is.

At the most protruding part of the lower surface of the housing 37, a protrusion 50 which is supported in direct contact with the four-point bottom surface 25 is extended along the end surface, thereby forming a support part A.

As described later, the instrument is supported at three points by the lock part D, the locking part C, and this support part A, but for this purpose, it is more effective to separate A from D and C as much as possible. can provide support.

Further, a groove 39 that can fit into the guide protrusion 26 is formed in the substantially hollow part of the lower surface, and by fitting the protrusion 26 and the groove 39 when installing the instrument, it is possible to It constitutes a guide portion B that acts as a guide for the instrument and also regulates the left and right position of the instrument within the recess.

Therefore, the structure allows automation of mounting.

Further, locking claws 41, 41 with tapered surfaces 40, 40 on the rear end side upper surface are provided on the left and right sides of the lower front end of the hood 38, corresponding to the locking holes 27.27, and these locking claws are provided after fitting the instrument. The claws 41, 41 fit into the locking holes 27, 27 and engage with the bottom end portions 28, 28, thereby forming a locking portion C that locks the lower part of the front end of the meter.
It consists of

The engaging members 30 are disposed on the left and right sides of the upper front end of the hood 38.
．． Protrusions 42, 42 are provided in positions opposite to the engagement members 30, projecting upward, so as to ride over the protrusions 31, 31 of the engaging members 30, 30 to be in a locked state, and operation holes are provided on the rear sides of the engagement members 30, 30, respectively. 43, 43 and engage member 30.30
A lock part D is configured so as to face the operating parts 32, 32 of.

In addition, in FIG. 3.5, the reference numeral 44 indicates the upper surface 2 of the recess.
A press spring piece is shown in which a tongue-shaped notch is formed in 9 and the press spring piece is bent slightly downward, and constitutes a press-contact part E that comes into elastic contact with and supports the upper surface of the housing 37 of the instrument.

Reference numeral 45 denotes a connection terminal attached to the rear surface of the housing 31 and fitted into the connector 36;
The mutual positional relationship is set appropriately in advance so that the positions match with each other.

Therefore, according to this configuration, when mounting the meter, it is sufficient to simply insert the meter 23 into the recess 24 through its opening in the attitude shown in FIG.

During insertion, the guide protrusion 26 in the guide portion B fits into the groove 39, so that the instrument 23 can be inserted straight into the recess, and the instrument fitting position within the recess is regulated.

By pushing the meter in, the connecting terminal 45 is fitted into the connector 36 fixed to the inner surface 33 of the recess 24 as it is.

When pushed in further, the protrusion 42.
42 climbs over the projections 31 and 31 while displacing them upward, and after getting over the projections 31 and 31, the projections 42 and 42 engage with each other.
That is, the meter 23 is locked so that it does not move forward.

At the same time, in the supporting part A, the four bottom surfaces 25 directly support the lower surface of the housing 37, and in the locking part C, the locking claws 41, 41 fit into the locking holes 27, 27, and the bottom end 25 directly supports the lower surface of the housing 37.
828 to restrain upward movement of the front end of the meter.

Further, in the pressure contact portion E, the pressing spring piece 44 presses the upper surface of the housing 37 downward, and restricts upward movement of the rear end of the instrument.

To explain this in detail, the meter 23 is supported at three points within the recess 24: the locking portion D1, the engaging portion C, and the supporting portion A, so it is supported extremely stably, and there is some damage to the meter. Even if vibrations are transmitted, the instrument can be reliably supported and prevented from falling off.

In particular, movement of the meter in the vertical direction can be prevented by the action of the locking part C and the pressure contact part E, and movement in the left and right direction can be prevented by the action of the guide part B.

Further, the front end of the instrument can be prevented from moving back and forth by the locking portion D and the engaging portion C.

Note that in order to remove the gauge 23 from the recess 24, remove the hood 3.
Insert your finger through the operation hole 43.43 of 8 and remove the retaining member 30.3.
If the operating portion 32.32 of 0 is pushed upward, the engaging member 30.
30 is displaced upward as shown by the imaginary line in FIG. 3 to form a protrusion 31.
31 and the protrusions 42, 42 are unlocked, and the instrument can be pulled out.

Regarding the above-mentioned lock part D, since the tenth surface 29 to which the protrusion 31 is attached is inclined, the protrusion 31 has a downward slope when, for example, a vehicle is rear-ended and an acting force is generated in the direction of the instrument jumping out toward the passenger. Since a biting moment is generated, a so-called self-locking function is generated, which increases safety in the event of a rear-end collision.

Note that this self-locking function becomes more effective as the angle of the inclined surface increases.

Here, as the pressing spring of the pressure contact portion E, a pressing spring 44A formed in the shape of a tongue facing rearward as shown in FIG. 6 can also be used.

Further, as shown in FIG. 7, a protrusion 46 is provided on the rear surface of the meter 23.
A boss hole 4 is provided on the back surface of the corresponding recess.
7, and when the projection 46 is fitted into the boss hole 41, the upper piece 47a of the boss hole 46 presses the projection 46, that is, the instrument, downward.

Furthermore, the projections 31.31 and 42 of the engagement member 30.30
．． In order to enhance the locking effect due to engagement with 42, as shown in FIG. Just add a little.

In addition, in order to facilitate the attachment of both protrusions, the taper angle of the front surface 31a of the protrusion 3L31 and the rear end surface 42a of the protrusions 42, 42 may be increased as shown in the figure.

As is clear from the above description, the instrument mounting structure of the present invention allows the instrument to be simply inserted into the recess formed in the support panel through the opening, and at least the instrument can be mounted on the support section provided on the bottom surface of the support panel, and the instrument mounting structure provided on the lower surface of the front end. Since the instrument can be supported by the locking part provided on the upper surface of the front end, it is extremely easy to install the instrument, and it also suppresses vibration transmission to the instrument and prevents it from falling off. can do.

Furthermore, by providing a pressure contact portion and a guide portion, support can be made even more reliable.

Furthermore, since the lock portion can be released very easily, the installation and removal work of the meter is also facilitated.
