Description

[Detailed description of the invention] The present invention relates to an improvement in the mounting structure of the knee panel located at the lower part of the instrument panel.In the event of a collision, etc., inertia force in the direction of vehicle movement is applied to the occupant. When the knee collides with the knee panel, the impact force is received at one end by the front pillar side via the side bracket, and at the other end by the floor side via the inverted L-shaped bracket. By using an L-shaped bracket, the impact force acts as a load toward both ends of the inverted L-shaped bracket, that is, in the tensile direction, thereby minimizing the deformation and movement of the knee panel and its supporting member. The purpose of this invention is to provide a mounting structure that provides a secure mounting structure, and to make the stiffness of each part of the knee panel equal, so that the load received by the knee during a collision is approximately the same everywhere on the knee panel.

Conventionally, this type of knee panel mounting structure has been as shown in FIG. There are many things that are fixed. This structure has the drawback that when the occupant's knees collide from the direction of arrow P, the dash brace C buckles or a large bending moment is applied to it, prolonging the displacement stroke of the knee panel D. Not only does the distance from the dash panel A to the fixing part of the knee panel D become long, which increases the weight and cost of the mounting components, but also depending on the structure of the cooler unit E located in the lower part of the instrument panel. It also had the disadvantage that the dash brace C could not be placed.

The present invention provides a knee panel mounting structure that does not have the above-mentioned drawbacks by having the configuration described in the claims of the utility model registration.

The configuration of the illustrated example will be explained below.

Figure 1 shows the disassembled mounting structure of the knee panel 1.
As shown from the front of the vehicle, on the lower part of the inner surface of the knee panel 1, there is a reinforcing material 2 having a dish-shaped cross section over almost its entire length, and a reinforcing material 2 with a concave surface facing the knee panel main body 4 and a welding etc. It is fixed to the knee panel main body 4 by. This reinforcing material 2 is provided with a window hole 5 for weight reduction.

The knee panel 1 has mounting parts 6 on both sides of the upper edge,
At 7, the reinforcing material 8 of the instrument panel (not shown) is passed through bolt holes 9 and 10 and fixed with bolts. It is bolted to a side bracket 13 that is fixed to the front pillar, and is fixed to the front pillar side via the bracket 13.

The other side 14 of the lower edge 11 is fixed together with the peripheral edge 3 of the reinforcing member 2 to the horizontal mounting portion 16 of the inverted L-shaped bracket 15 by bolt connection.

In the illustrated embodiment, a center brace 19 located on the vehicle center side is erected and fixed to a floor bracket 18 fixed to a floor 17.
By fixing the vertical mounting portion 20 of the inverted L-shaped bracket 15 to the center brace 19, the other side 14 of the lower edge 11 of the knee panel 1 is fixed to the floor side.

Now, when an inertia force in the vehicle traveling direction is applied to the occupant and the occupant's knee collides with the knee panel 1 from the direction indicated by the symbol P in FIG. Due to the presence of the member 2, the impact force is received by the entire knee panel 1 without causing local deformation in the knee panel main body 4, and is further transmitted to the vehicle body via the side bracket 13 and the inverted L-shaped bracket 15. will be paid and paid. Since the knee panel 1 is a reinforcing material 2, the load on the knee is approximately the same no matter which part the knee collides with.

At this time, the upward component of the impact force in the direction indicated by the symbol P is applied to the inverted L-shaped bracket 15.
The load acts as a tensile load in the direction shown by arrows X and Y, that is, in a direction substantially parallel to the horizontal mounting portion 16 and the vertical mounting portion 20 of the inverted L-shaped bracket 15, and the mounting portion of the knee panel 1 is subjected to a strong tensile load. It has a strong strength.

Since the first side 12 of the lower edge 11 is fixed to the front pillar side through the side bracket 13 together with the peripheral edge 3 of the reinforcing member 2, it is inherently strong and rigid.
Its strength is great.

As a result of the above-mentioned action, the deformation and displacement of the knee panel 1 becomes slight, which effectively restrains the knees of the occupant and prevents the occurrence of the so-called submarine phenomenon. too,
The load that the knee receives is approximately equal.

Therefore, by providing the mounting structure using the inverted L-shaped bracket 15 on the vehicle center line side, the knee panel mounting structure can be improved compared to the conventional one.
It can be made extremely strong.

The present invention has the above-mentioned structure and function, and when an inertia force in the vehicle traveling direction is applied to an occupant and the occupant's knee collides with the knee panel, the impact force is directly absorbed by one side of the lower edge of the knee panel. It can be transmitted to the vehicle body side, and on the other side of the lower edge, it can be applied as a tensile load to the inverted L-shaped bracket, and it can also be transmitted to the vehicle body side and received, so that the mounting member does not buckle. Since there is no generation of areas where large bending moments are applied, deformation and movement of the knee panel and its supporting members can be minimized, and the mounting structure is relatively simple. It is possible to leave a large space inside the knee panel, which also has the advantage of forming a large space for equipment such as a cooler unit.

No matter where the load is applied, the rigidity of the knee panel is equal and large in each part, so that no local deformation occurs, and no matter where on the knee panel the knee hits, it prevents the knee from moving. The submarine phenomenon can be suppressed to an appropriate level, and the submarine phenomenon can be effectively prevented, and the load on the knee can be made to be approximately the same regardless of where on the knee panel the knee panel collides.
