Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle instrument panel positioning structure for positioning and connecting an upper portion of an instrument panel to a dash panel.

[0002]

2. Description of the Related Art In recent years, automation of vehicle assembly has been promoted, and as disclosed in, for example, Japanese Patent Application Laid-Open No. 1-145284, a robot is used to assemble an instrument panel to a dash panel. .. With the automation of such instrument panel assembly work, in order to speed up and simplify the assembly work by the robot, the connection between the upper part of the instrument panel and the dash panel, which does not require particularly high strength, is connected to the dash panel. Formed positioning hole,
It is performed by fitting with a panel connecting member provided on the instrument panel.

The operation by the robot at this time will be described with reference to FIG. 6 which is an explanatory view of the embodiment of the present invention. First, as shown by a chain double-dashed line, the instrument panel 1
However, the upper part is inclined toward the vehicle compartment side, and the engaging recess 9 of the lower connecting portion 9
a is engaged with the engagement pin 8a of the tunnel portion 8 of the floor panel. Next, the instrument panel 1 is mounted on the dash panel 7 with the engagement pin 8a as the center.
The panel connecting member 31 provided on the upper portion of the instrument panel 1 is fitted into a positioning hole (not shown) of the bracket 17 provided on the dash panel 7.

Here, the conventional panel connecting member 31 is used.
As disclosed in Japanese Utility Model Laid-Open No. 62-103739, it is made of an elastic member and has a frontwardly extending inclining slope. The panel connecting member 31 is guided by the above-mentioned inclining slope and fitted into the positioning hole formed in the dash panel.

[0005]

However, the instrument panel 1 is a heavy object, and when supported by the lower end as a fulcrum as described above, the instrument panel 1 bends downward due to its own weight. The panel connecting member 31 provided on the upper portion is likely to be displaced in the vertical direction with respect to the positioning hole. For this reason, although the panel connecting member 31 is required to have a large-area inclining slope, the conventional connecting slope of the panel connecting member 31 is formed as a continuous surface on the front surface of the panel connecting member 31. However, it is not possible to secure a sufficiently large area for a positioning hole of a certain size.
Therefore, it is difficult for the panel connecting member 31 to be fitted into the positioning hole. On the other hand, it is conceivable to make the positioning hole large so that the panel connecting member 31 can be easily fitted into the positioning hole. However, in such a structure, the panel connecting member 3 is formed.
However, it is not possible to deal with this by increasing the size of the device 1, that is, by increasing the size of the connection structure.

[0006]

In the vehicle instrument panel positioning structure of the present invention, in order to solve the above-mentioned problems, a panel connecting member is provided on the upper portion of the instrument panel body while the above-mentioned dash panel is used. A positioning hole is formed at a position corresponding to the panel connecting member of the above, and the panel connecting member has a positioning leg that is inserted into and fitted into the positioning hole, and the front portion of the positioning leg has elasticity. However, it is branched into upper leg and lower leg that can be deformed in the direction opposite to each other.At the front of the upper leg and the lower leg, there are beveled faces for guiding the legs to the positioning holes. The front end of each of the intake slopes is displaced from each other with respect to the positioning hole, and the lower end of the front slope of the intake slope of the upper leg is formed.
The upper end portion of the front end portion of the inclining slope of the lower leg portion is aligned with the virtual plane that extends in the extending direction of the positioning leg and divides the positioning leg into two substantially evenly in a direction perpendicular to the extending direction. And a locking portion for engaging with the outer periphery of the positioning hole and restricting the withdrawal of each leg from the positioning hole is formed at the rear end of each of the intake slopes. There is.

[0007]

According to the above construction, the positioning leg of the panel connecting member is inserted into and fitted into the positioning hole of the dash panel so that the upper leg portion and the lower leg portion of the positioning leg are attached to the respective inclining slopes. It is performed by being guided and deformed in the directions opposite to each other. Further, the upper and lower leg portions inserted into the positioning hole are restricted from being removed from the positioning hole by the respective locking portions.

In the process of fitting the panel connecting member into the positioning hole, the deformation operation required for the upper and lower legs is such that the front end portions of both the inclining slopes are displaced from each other with respect to the positioning hole. Therefore, it is not hindered by the interference between the calling slopes.

Further, the two inclining slopes are such that the front ends of the two inclining slopes are displaced from each other with respect to the positioning holes in the front and rear, and the lower end of the front leg of the inspiring slope of the upper leg and the lower leg. The upper end of the front end of the intake slope is formed so as to coincide with a virtual plane that extends in the extending direction of the positioning leg and divides the positioning leg into two substantially evenly in a direction perpendicular to the extending direction. By doing so, the projected area of the positioning hole in the insertion direction can be increased. Therefore, even when the instrument panel bends downward due to its own weight and the vertical position of the panel connecting member with respect to the positioning hole is slightly displaced, the panel connecting member can be fitted into the positioning hole appropriately.
