Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of an instrument panel section in an automobile.

[0002]

2. Description of the Related Art As a structure of a conventional bench rating system, there is, for example, a structure shown in FIG. In this system structure, a heater unit 52 of an air conditioner is arranged in front of the instrument panel 51 in the vehicle body, and the heater unit 52 is composed of a heater unit main body 53.
And a plurality of centers and side ducts 54 and 55 arranged from the heater unit main body 53 through the inside of the instrument panel 51. The ducts 54 and 55 are connected to the instrument panel 51.
It is connected to the center vent louver 56 and the side vent louver 57 arranged on the side. The periphery of the vent louvers 56 and 57 is covered with a garnish 58.

[0003]

However, in the above-mentioned conventional structure, since the parts such as the plurality of ducts 54, 55, the vent louvers 56, 57 and the garnish 58 around the louvers are used, the number of parts and the number of parts are set. It has a drawback that the number of attachment steps is large, there is a problem in assembling workability, and the cost of parts is high. Further, during the impact test of the instrument panel 51, the internal ducts 54, 55 and the like may be damaged by the impact force.

The present invention has been made in view of the above circumstances, and an object thereof is to reduce the number of parts and the number of assembling steps and to improve the absorbability of impact energy. To provide the structure of.

[0005]

In order to solve the above-mentioned problems of the prior art, in the present invention, an instrument panel body having a mounting hole on the front surface on the indoor side and a separate body from the instrument panel body. And a hollow body that forms a part of the instrument panel in a state of being assembled to the instrument panel body, and a plurality of outlets are provided on the front surface of the hollow body on the indoor side. A duct is provided by providing a connecting portion on the rear surface of the hollow body on the side opposite to the air outlet, and connecting the connecting portion to an air conditioner through a mounting hole of the instrument panel body to assemble the hollow body. Is configured as.

[0006]

[Operation] In the structure of the instrument panel section according to the present invention, the hollow body forming a part of the instrument panel in the state of being assembled to the instrument panel body has a function as a duct. , The ducts and garnishes used in the conventional bench rating system structure are unnecessary. Further, since a part of the instrument panel has a hollow structure with a hollow body, it is easily deformed by the impact force applied to the instrument panel portion and has a high impact absorption property.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on the illustrated embodiments.

1 to 3 show an embodiment of the structure of an instrument panel section according to the present invention. In the figure, reference numeral 1 denotes an instrument panel that is assembled to a vehicle body on the indoor side of a four-wheeled vehicle 2, and the instrument panel 1 is an instrument panel main body that is formed into a curved shape as a whole toward the indoor side. 3 and a hollow body 4 formed separately from the instrument panel body 3.

A meter cluster 6 for accommodating measuring instruments such as a speedometer and an engine tachometer is provided on a front surface portion 5 on the indoor side, which is located on the driver's seat side of the instrument panel body 3, and the front surface portion 5 is substantially centered. At the position, a rectangular mounting hole 7 for mounting a connecting portion described later is formed. Further, on the upper surface of the instrument panel body 3 on the passenger seat side, a storage rack 8 formed by a recess is provided.

Further, the upper side of the front surface portion 5 of the instrument panel main body 3 is formed in an L-shape when viewed from the side for assembling the hollow body 4, and the vertical surface portion 5a has a height higher than that of the hollow body 4. It is formed in almost the same size as. And
An insertion hole 9 for inserting a clip described later is formed in the vertical surface portion 5a. Further, the flat surface portion 5b is formed substantially horizontally and has a size such that the hollow body 4 mounted and assembled is flush with the instrument panel body 3. A recess 10 is provided on the back side of the flat portion 5b so that the hollow body 4 is prevented from falling by engaging with the hollow body 4 to be assembled.

On the other hand, the hollow body 4 constitutes a part of the instrument panel 1 in a state of being assembled to the instrument panel body 3, and has a box-shaped hollow structure extending along the vehicle width direction. Has become. Then,
The hollow body 4 includes a box member 11 and a surface member 12 that covers the upper surface and the front surface of the box member 4, and is arranged over the entire width of the instrument panel body 3.

A plurality of air outlets 13 are provided on the front surface 4a of the hollow body 4 on the indoor side. Two air outlets 13 are provided at the central position in the vehicle width direction, and one air outlet 13 is provided on each of the left and right sides. It is set up. Then, these outlets 13 have a center vent louver 14 or a side vent louver 15 respectively.
Is installed. In the center of the rear surface 4b of the hollow body 4 on the side opposite to the air outlet 13, a connecting portion 16 communicating with the inside is provided.
Is provided, and the connecting portion 16 is connected to a heater unit of an air conditioner (not shown) through the mounting hole 7 of the instrument panel body 3. Therefore, the connecting portion 16 of the hollow body 4 is formed in a rectangular shape corresponding to the mounting hole 7 of the instrument panel body 3.

On the rear surface 4b side of the hollow body 4, a projecting piece 17 integrally formed with the box member 11 is provided corresponding to the insertion hole 9 of the instrument panel body 3, and these projecting pieces are provided. A clip 18 having elasticity is attached to 17. A ridge portion 19 that engages with the recess 10 of the instrument panel body 3 is formed on the inner side of the lower surface of the box member 11.

In such an instrument panel structure, the hollow body 4 is placed on the flat surface portion 5b of the instrument panel body 3, and the clip 18 is attached to the vertical surface portion 5a.
Insert the connecting part 16 into the insertion hole 9 of the
It is connected to a heater unit (not shown) via the. Then, the hollow body 4 is integrated with the instrument panel body 3 and constitutes a part of the instrument panel 1. Further, the air from the heater unit is introduced into the hollow body 4 via the connection portion 16, and is sent out from the center vent louver 14 and the side vent louver 15 to the indoor side through the inside of the hollow body 4. That is, the hollow body 4 functions as an air duct.

The embodiment of the present invention has been described above.
The present invention is not limited to the embodiments described above, and various modifications and changes can be made based on the technical idea of the present invention.

For example, the hollow body 4 in the above-mentioned embodiment
The shape of is not limited to those shown in FIGS. 2 and 3, and can be appropriately selected according to the shape of the instrument panel body 3 to be assembled.

[0017]

As described above, the structure of the instrument panel portion according to the present invention is formed separately from the instrument panel body, and is a hollow body that constitutes a part of the instrument panel when assembled. Since the hollow body is configured as a duct by connecting the hollow body to the air conditioner through the attachment hole of the instrument panel body and assembling the hollow body, the hollow body is required in the conventional bench rating system structure. It is possible to omit the duct, garnish, etc., which were previously described, and it is possible to reduce the component cost by reducing the number of components and the number of assembly steps. Further, in the instrument panel portion of the present invention, since the front surface portion on the indoor side has a hollow structure by the hollow body, it is possible to effectively absorb the impact energy applied to the instrument panel, The effect can be further enhanced by forming the body surface with a cushion material or the like.
