Abstract

PURPOSE:To achieve a lighter weight and an easier construction and manufacture by holding an interior material with a foaming body of resin bead to eliminate an inner plate. CONSTITUTION:Large spaces S1 and S2 are defined on a door inner plate inside the room of a vehicle except for periphral frames 4 and a cross member 5 to achieve a reduced weight accordingly. A door lining 9 is applied and connected on the inside of the door to close the internal surface of the frames 4 and the cross member including the spaces S1 and S2. The door lining 9 is made up of a foam body produced by thermally foaming a foam resin bead. When applying the lining 9, the periphery of the inner surface thereof is fitted on the frames 4 of the door 1 and engaging pieces previously provided along the periphery thereof are engaged with mount holes 4C provided on the frames 4. Otherwise, it is put together with the frames by a screw or the like.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of an interior material portion forming the interior side of a vehicle body or door.

The vehicle body, also known as the door or white body, consists of an inner and outer panel made of press-formed steel sheets, and the inner surface of the inner panel of the door or body is designed with soundproofing, appearance, etc. in mind. A lining is attached as an interior material.

Conventional doors and bodies are heavy because they have a double structure consisting of an outer panel and an inner panel that covers the entire surface, and the interior material is also heavy because it is made of panels such as synthetic resin. is desired.

The present invention has been made to improve the above []
The target area is to mold the interior material, that is, the lining of the inside of the body and the door lining, with resin beads, especially polypropylene resin bead foam, and in conjunction with this, the interior material of the body and the interior of the door are omitted, and the outside is molded. The object of the present invention is to provide an interior structure for a vehicle that is lighter in weight and easier to construct and manufacture by bonding and pasting the lining on the inner surface of the plate.

Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

In this example, an example was explained in which it was applied to a front door.
It can be implemented on the rear door or the inner plate of the body.

The door 1 has an outer panel 2, and an inner frame 3 is joined at the outer edge of the four peripheries on the inner surface of the outer panel 2. A frame portion 4 is formed on all four sides, and in the embodiment, a cross member 5 is provided that connects the middle portions in the height direction of the front and rear vertical frame portions 4a and 4b.Therefore, the door inner plate is formed on the inside of the vehicle. A large space S, S2 is formed except for the four circumferential frame portions 4 and the cross member 5, and it is possible to plan to convert the door into an IpR.
A sash 6 is installed at the -L end, and a window 7 surrounded by the sash at the upper edge of the door is opened and closed by raising and lowering the glass plate 8, and the door 1
A window regulator and the like (not shown) are installed inside.

The door lining 9 is pasted and combined on the inside of the above door, and the space 31. The frame portion 4 including S2 closes the inner surface of the cross member. The door lining 9 is formed of foamed resin beads, preferably polypropylene resin beads heated and foamed. The lining 9 is integrally formed with an armrest 11 on the surface of the intermediate part of the plate-shaped main body 10, and is provided with a handle case mounting hole 12 in the upper intermediate part, and a handle handle insertion hole 13 in the lower part thereof. In the embodiment, a groove 14 that opens toward the door is formed at the upper end to form a U-shaped cross section, and a duct is formed in the installed state, and an air outlet 15 is provided in the upper piece to direct air from the air conditioner into the duct. It was introduced and used as a Zydomister to prevent glass plates from fogging.

The above-mentioned lining 9 is applied to the frame 4 of the door 1 with its inner four circumferences, and by providing retainers on the four circumferences of the lining 9 in advance, it is attached to the mounting holes 4C provided in the frame 4. Connect with screws, etc. In this case, a cross member 5 is installed in the middle of the frame 4.
Since the armrest 1 of the lining 9 is provided as shown in FIG.
A reinforcing member 16 may be embedded in one portion and fixed to the cross member 5.

By the way, since the lining 9 is made of polypropylene resin bead foam, it has excellent heat insulation, water resistance, oil resistance, and chemical resistance, as well as strength and rigidity, and is lightweight, as well as having elasticity and a good feel. In particular, the lining 9 constitutes the inner panel of the door, and therefore the lining side rotor mechanism etc. are directly exposed, and even if the grease etc. of these mechanisms adheres to the inner surface of the lining or moisture adheres, it is oil resistant, water resistant, and chemical resistant. Because of its excellent properties, the lining can be configured directly as the inner door panel.

FIG. 4 shows a modified embodiment of the above-mentioned embodiment, in which the above-mentioned frame portion 4
The cross member 55 installed in the cross member 55 has a cross shape with a width 55a and a length 55b.

5 to 7 show a second embodiment.

Inner frame 103 joined to the four inner circumferences of the outer panel 102 of the door 101
Only a frame portion 104 is formed in the frame portion 104, and four substantially rectangular spaces S3 are formed in the frame portion 104 so as to open inward. On the other hand, the lining 109 is armless N as described above.
Lining 1090 Inside the main body 110, in the embodiment, two narrow reinforcing plates 117.
17 is buried, and a cross member 118 is provided between the reinforcing plates 117 and 117 at intermediate portions in the height direction to connect them. As shown in FIG. 7, it was cut into a cross-sectional shape and was embedded in the armrest 111. Above reinforcing plate 117.117, cross member 1
18 are bonded in advance, set in a mold, and further filled with resin beads in the molding groove and heated and foamed to form a lining. Incidentally, the upper and lower ends of the reinforcing plate i17.117 are bent into a U-shape to form projecting pieces 117a, 117a on the back surface, and engaging protrusions 119 are protruded from these, and these 7 valves are attached to form the frame part 104.
(The disposed lining 109 engages with the locking holes 104a, etc. in the frame part and is coupled to the inside of the door so as to close the space S3.

In this way, the reinforcing member may be embedded in the lining side and not provided in the door side, and both may be connected. According to this embodiment, the structure of the door is further simplified.

In the above examples, polypropylene resin bead foam was used, but polystyrene resin bead foam may also be used (Also, although it was used for the door in the example, the inner plate on the body side other than the door was constructed as described above. Of course, it is okay to do so.

As is clear from the above, according to the present invention, it is possible to significantly reduce the weight of the door, and since the inner panel is composed of a lining, the structure of the door is simplified compared to conventional ones, and furthermore, the door is made of polypropylene resin. By using bead foam, the above can be achieved without adopting a water-resistant or oil-resistant structure, and there are many advantages such as further simplifying the structure, reducing the number of parts, and simplifying manufacturing. has.
