Summary of the invention

But,, therefore have the problem of sound insulation value difference because this unit installation constitution is not considered sound insulation.

The objective of the invention is to, a kind of unit installation constitution that can improve sound insulation value is provided.

The present invention relates to a kind of unit installation constitution, it is analog bracket on the vehicle-body outer panel that is covered by coated material, by this carriage the unit is installed on the described vehicle-body outer panel, it is characterized in that, on the attachment face that the unit is installed of described carriage, form the boss that protrudes to described cell side, the hole of exposing of described boss embedding is set on described coated material, make described boss insert the described hole of exposing, described unit is installed simultaneously.

The effect of invention

According to the present invention, because the carriage except boss is covered by coated material, therefore installation unit on this boss can improve sound insulation value.

The specific embodiment

Below, based on accompanying drawing, to as the embodiment of unit installation constitution of the present invention

Embodiment describes.

Embodiment

In the unit installation constitution of Figure 1 and Figure 2, be provided with: floor (vehicle-body outer panel) 1; Carpet (coated material) 2, it covers floor 1; Carriage 10, it is installed on the floor 1; And sensor unit (unit) 30, it is installed on this carriage 10.

On carpet 2, as shown in Figure 3, what be provided with that the boss 14,15 (with reference to Fig. 4) of carriage 10 described later embeds exposes

hole

4,5, and simultaneously, carpet 2 also covers carriage 10 integral body except this boss except covering floor 1.

Carriage 10 possesses as shown in Figure 4: roughly rectangular baseplate part 11, and its surface becomes attachment face 11A; A pair of

foot

12,12, it is formed at the both sides of this baseplate part 11;

Flange

13,13, it is formed at the bottom of this

foot

12,12; And

circular boss

14,15, it is formed on the baseplate part 11.

Boss

14,15 protrudes upward, and its

upper surface

14A, 15A form plane, forms

mounting hole

14a, 15a on upper surface 14A, 15A.

Captive nut

16,17 in this

mounting hole

14a, 15a.

In addition, the side opening (opening) of a boss 15 as shown in Figure 5, in the upper edge and the both sides of the edge portion of opening 18, forms

flange

18a, 18b, 18c.The upper surface of flange 18a and baseplate part 11 forms abreast.So carriage 10 becomes the state that has cut off right side part (Fig. 4) from the position, side of boss 15.

Sensor unit 30 possesses as shown in Figure 1: shell 31, and it is built-in with air bag sensor (not shown) etc.; And flange 32, it is formed at the bottom of this shell 31.On flange 32, form

bolt hole

32a, 32a (with reference to Fig. 2).

Below, the installation method of sensor unit 30 is described.

At first, the

flange

13,13 with carriage 10 utilizes methods such as bolt or welding to be fixed on the floor 1.Then, carpet 2 is installed, is covered floor 1 and carriage 10 by carpet 2 as shown in Figure 3.At this moment, make the

boss

14,15 of carriage 10 embed exposing in the

hole

4,5 of carpet 2, expose so that

boss

14,15 exposes

hole

4,5 from this.The position of exposing

hole

4,5 of carpet 2, than the position of upper surface (face of joint) 14A, the 15A of

boss

14,15 more by the below.

By making

boss

14,15 embed exposing in the

hole

4,5 of carpet 2, can easily locate carpet 2.In addition, expose in the

hole

4,5 for circular the embedding easily, therefore can successfully carry out the position adjustment of carpet 2 by making

boss

14,15.

Subsequently, with the

boss

14,15 of the flange 32 of sensor unit 30 and carriage 10 as shown in Figure 2, utilize bolt B to fix, sensor unit 30 is installed on the boss 14,15.Because

boss

14,15 is from the protrusion the

hole

4,5 that exposes of carpet 2, so the installation exercise of sensor unit 30 is easy.In addition, by

boss

14,15 is set, improve the rigidity of the installation position of sensor unit 30.In addition, owing to utilize upper surface 14A, the 15A of

boss

14,15 that sensor unit 30 is installed on the carriage 10, thereby carriage 10 is that required Min. get final product with respect to the face of joint of sensor unit 30, so can suppress to send noise by this face of joint.

In addition, utilize the installation of sensor unit 30, as shown in Figure 2, the edge part that exposes hole 4 of carpet 2 is by sensor unit 30 and carriage 10 clampings, and this exposes hole 4 and is stopped up by sensor unit 30, so sound insulation value improves.In addition, less in Fig. 1 flange 32, expose hole 4 and do not stopped up, but in fact as shown in Figure 2, expose hole 4 and stopped up by the flange 32 of sensor unit 30 by sensor unit 30.

If the installation of sensor unit 30 then is installed in not shown control box on the assigned position.As shown in Figure 6, installation because of control box 40, carpet 2 is by from the direction of opening 18 side direction boss 14 (the figure left to) extruding, the hole 5 of exposing of carpet 2 is pushed to left among the figure thus, its edge part 5A that exposes hole 5 is pushed to the opening 18 of the boss 15 of carriage 10, and the space between the edge part 5A that exposes hole 5 of carpet 2 and the boss 15 of carriage 10 disappears, as shown in Figure 7, the opening 18 of boss 15 is stopped up by the felt layers 2A of carpet 2 and napping 2B, and sound insulation value is improved.In addition, 2C is a underlayment.

In addition, the boss 15 by the edge part 5A that exposes hole 5 of carpet 2 is pushed to carriage 10 can cover carriage 10 by carpet 2 as much as possible, so can further improve sound insulation value.In addition, because the edge part 5A that exposes hole 5 of carpet 2 is pushed to the opening 18 of boss 15, its shedding deformation that exposes hole 5 is suppressed, thereby has prevented the skew of carpet 2, can guarantee the bond quality with control box 40.

In addition, by the side opening of boss 15, can prevent that the edge part 5A that exposes hole 5 of carpet 2 crosses on the boss 5 when the installation and control case.In addition, by the side opening with boss 15, what can reduce carpet 2 exposes hole 5, further improves sound insulation value.

In addition, owing to can on the recess between the

boss

14,15, dispose carpet 2, thereby can further improve sound insulation value.

Carriage 10 as shown in Figure 5, can carry out face by

face

11a, 11b on the baseplate part 11 of the both sides of boss 15 and these three faces of flange 18a supports, therefore when cutting because of punch forming, can use the side cut method, with the right side quadrate part branch (the right side part of opening 18) of the boss 15 that cuts carriage 10 to greatest extent, thereby make carriage 10 be minimal size.

More than, the embodiment of preferred forms of the present invention is illustrated, but is not limited in this embodiment, the design modification of degree that does not break away from purport of the present invention is all in the present invention involved, for example, be not limited only to the sensor unit 30 that safety air bag is used, also be applicable to other unit.As other example, can also be applicable to the acceleration pick-up of use in the system in control vehicle action (so-called VDC system) etc.

Equally, being not limited in carpet 2, also can be other lining material such as cloth for example.In addition, sensor installation unit 30 on the carriage 10 that is fixed on the floor 1 is illustrated, but analog bracket 10 be not limited to floor 1, also can be other vehicle-body outer panel.
