DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a side body structure of an automobile.

[0002]

2. Description of the Related Art As this type of technique, for example, as shown in FIGS. 8 and 9 (see Japanese Utility Model Application Laid-Open No. 63-117671), a center pillar lower panel 3 has a closed cross section 4 formed by an outer panel 1 and an inner panel 2. An opening 5 communicating with the closed section 4 is formed in the inner panel 2.
Reference numeral 6 denotes a sound insulating member disposed in the closed section 4 near the opening 5, and is made of polyurethane foam. This sound insulation member 6 is for preventing the stone jumping sound and the muffled sound.

[0003]

However, in an automobile in which the center pillar lower panel 3 is not disposed on the upper surface of the side sill 7 such as when the body side outer panel (not shown) is formed integrally with the side sill 7, the sound insulating member 6 is not provided. May fall into the inside of the side sill 7 due to deterioration with time or the like. In such a case, not only the sound insulation effect is reduced, but also the position where the sound insulation member 6 is disposed is unpainted, which may cause rusting.

When a seat belt retractor (not shown) is provided using the opening 5, a sound insulating member 6 is provided.
If the webbing (not shown) is pulled out when the webbing (not shown) is pulled out due to deterioration with time or the like, the sound insulating member 6 may be caught by the webbing and may be drawn into the room.

When the sound insulating member 6 moves in the center pillar lower panel 3 due to the vibration of the automobile, a gap is generated between the closed section 4 and the sound insulating member 6, and the expected sound insulating and dustproof effects are exhibited. It may not be possible.

Accordingly, the present invention has ensured sound insulating and dustproof performance by preventing the sound insulating member in the side body structure from being dropped due to deterioration, and by reliably closing the gap between the closed section and the sound insulating member. It is an object of the present invention to provide a side body structure of an automobile.

[0007]

According to the present invention, there is provided a side body structure of an automobile, wherein an outer panel and an inner panel are formed in a closed cross section and an opening communicating with the closed cross section is formed in the inner panel. A sound insulating member is provided in the closed cross section near the opening, and the sound insulating member supports a sound insulating material formed in advance so as to vertically separate the closed cross section, and supports the sound insulating material. It is made of a plate material that is harder than the sound insulating material, and has a projection formed on one side portion of the plate material to be engaged with the peripheral portion of the opening, and the other side portion of the plate material is formed on a projection portion arranged on the outer panel. so as to engage, the
It is characterized in that a plate material is configured to be removable through the opening .

[0008]

[Operation] According to this structure, since the sound insulating member is supported by the plate material, the sound insulating material does not fall into the side sill even if the sound insulating material is deteriorated. As a result, it is possible to ensure the sound insulation and dustproof performance without deformation.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below in detail with reference to the drawings. 1 to 4, a center pillar lower panel 3 as a “car side body structure” is formed in a closed cross section 4 by an outer panel 1 and an inner panel 2 and communicates with the inner panel 2 in the closed cross section 4. 5 are formed.

Reference numeral 10 denotes a sound insulating member, which is a sound insulating material 11 made of a soft material such as polyurethane foam or polyethylene, which separates the closed section 4 from above and below, and a double-sided adhesive tape 12 (which may be an adhesive). supporting and shielding sound material 11 from the hard ABS through, polypropylene, polyvinyl chloride, synthetic resin or aluminum, such as nylon, a plate member 13 made of a metal plate such as iron becomes more.

A protruding portion 14 is formed on one side portion 13a of the plate member 13 so as to engage with the lower peripheral portion 5a of the opening 5.
Further, the other side portion 13b of the plate member 13 is
Is engaged with the projection 15 formed by cutting and raising the cutout. According to this embodiment, since the plate 13 is provided, deformation of the central portion of the sound insulating member 10 is suppressed, so that bending during the assembling work is prevented.

Further, since the sound insulating material 11 is mounted on the projection 15 formed by cutting and raising the outer panel 1 or on the door switch 16, the sound insulating member 10 is held by these parts 15, 16 and the like from under the sound insulating member 10. Is done. Furthermore, since the surrounding sound insulating material 11 is a soft member, even if the center pillar lower panel 3 as the "automobile side body structure" has a somewhat complicated cross section, the center pillar lower panel 3 can follow and generate a reaction force. improves.

FIG. 5 is a front view of the embodiment in which the anchor bracket 18 of the seat belt 17 is fixed to the side sill 7 and is screwed together with bolts 19. The retractor 20 of the seat belt 17 faces the opening 5 and also serves as an entrance and exit for the webbing 21.
The reference numeral 15a in FIG.

FIG. 6 shows a second embodiment of the present invention. The main difference from the first embodiment is an example in which a sound insulating material 11 is mounted on a plate 13, and the other is the same as the first embodiment. Is the same. In the case of this embodiment, even if the sound insulating material 11 deteriorates with time, the plate 13 is located on the lower side, so that the sound insulating material 11 can be held more reliably than in the first embodiment.

FIG. 7 shows a third embodiment of the present invention. The main difference between the third embodiment and the first embodiment is that the protruding portion 14 of the plate 13 is bifurcated, and the terminal portions 14a are bent downward to form openings. 5 is locked to the lower peripheral edge portion 5a, and the other components are the same as those of the first embodiment. In the case of this embodiment, it is bridged between the projection 15 and the lower peripheral portion 5a of the opening 5. In the present embodiment, the projections 15 are formed by cutting and raising the outer panel 1. However, the projections may be formed by embossing the outer panel 1, or another bracket may be provided on the outer panel. A projection may be provided.

[0016]

As is evident from the foregoing description, according to the vehicle side body structure of the present invention, an opening communicating with the closed section and is formed in a cross-sectionally closed shape to the inner panel between the outer panel and the inner panel is formed Rutotomoni to be in disposed sound insulating member in the closed plane of the opening near the sound insulating member is formed of the closed section formed in advance so as to isolate the upper and lower and sound insulating material, supports the shielding sound material A projection made of a plate material harder than the sound insulation material, the projection portion being formed on one side of the plate material to be engaged with a peripheral portion of the opening, and the other side portion of the plate material being disposed on the outer panel; so as to engage the parts, the
Since the plate material is configured to be able to be inserted and removed through the opening , the sound insulating member supports the sound insulating material by the plate material, so even if the sound insulating material deteriorates, it does not fall into the side sill, and the sound insulating material material is not deformed because no apply loads to the sound insulating material itself be degraded over time, will be able to secure the sound insulation, dust resistance, can be prevented from falling due to aging of the sound insulation material in the vehicle body side structure, By reliably closing the gap between the closed section and the sound insulating member, there is a practical effect that sound insulating and dustproof performance can be ensured.
