Description

  The present invention relates to a soundproof structure of a vehicle.

  2. Description of the Related Art Conventionally, in vehicles such as automobiles, a ventilator is provided for ventilating air in the cabin to the outside in order to alleviate ventilation in the cabin and pressure increase in the cabin when the door is opened and closed. However, noise from this ventilator may enter the cabin. In order to solve such a problem, for example, the ventilation structure of Patent Document 1 is disclosed.

  The ventilation structure of Patent Document 1 describes that the air passage of the ventilation is formed by an insulator member provided in an interior material of a passenger compartment and an outer plate member of a vehicle body. The insulator member is standardly installed as a basic structure of the interior of the passenger compartment for the purpose of heat insulation, sound insulation and sound absorption from the outside of the vehicle. Sound absorption and sound insulation are performed by this insulator member.

  In the above-mentioned prior art, it is possible to make noise and sound insulation inexpensively without using a dedicated soundproofing material. However, there has been a problem that the position of the air passage is limited to the position where the insulator member which is the interior material of the cabin is disposed, and the position of the ventilator is restricted.

  According to the first aspect of the present invention, the soundproof cover provided between the inner panel and the outer panel blocks the sound traveling toward the interior of the passenger compartment from the opening constituting the ventilator. This will not limit the position of the ventilator. And since it is not necessary to provide a soundproof material etc. on the panel whole surface, cost reduction can also be aimed at.

  A soundproof structure of a vehicle according to an embodiment of the present invention will be described with reference to FIGS.

  First, the vehicle before describing the soundproof structure of the vehicle will be described. In the vehicle, an engine room and a passenger compartment are formed from the front in the front-rear direction. The vehicle of the present embodiment is a hatchback type vehicle in which a trunk room is formed behind a cabin. A plurality of seats such as a driver's seat, a passenger seat, and a rear seat are arranged in the cabin.

  The vehicle body is comprised of an outer panel disposed outside and an inner panel disposed inside.

  The soundproof structure 1 of the vehicle according to the present embodiment includes a ventilator member 2 and a plate-like soundproof cover 3 as shown in FIGS. 4 to 7. As shown in FIG. 2, the ventilator member 2 is attached to an opening 5 provided in a side body outer panel 4 (outside panel) covering both sides in the width direction of the vehicle. The opening 5 is provided behind the rear tire of the side body outer panel 4 and below the trunk room in the passenger compartment. That is, in the present embodiment, the panel provided with the opening 5 is not a panel forming a passenger compartment. Further, in the present embodiment, the ventilator member 2 and the opening 5 constitute a ventilator.
