Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an upper back structure for a passenger car.

<Prior Art> The structure of the upper back section below the back window of a passenger car is as follows. That is, as shown in FIG.
A downward U-shaped bent edge 2 is formed in the vehicle width direction at the front end of the curved edge 2, and an Atsupabatsu clean force 3 is connected to the lower surface of the bent edge 2 to form a closed cross section. As shown in FIGS. 4A and 4B, it has a structure in which a rear spring support 5 is connected to a rear wheel house 4 via a wheel house reinforcement 6 and a bracket O-package tray 7.

<Problem that the invention attempts to solve> This atsupa back is one of the important members that maintains the body rigidity between the left and right rear wheel houses, but the wheel house reinforcement 6 and the atsupa back panel as described above Since the joint between the bent edge 2 at the front end of the rear spring support 1 and the closed section formed by the flat clean force 3 lacks rigidity, the floor 8 between the rear spring supports 5 is fixed as shown in FIG.
Atsupa cross member 9 is fixed on top, and both ends of Atsupa cross member 9 and rear spring support 5 are connected with a gusset wheel house 10, and the wheel house reinforcement 6 and floor 8 are connected to each other.
A reinforcing means is provided in which these are connected by a strainer panel 11. Therefore, three members, the atsupak cross member 9, the gazette wheel house 10, and the strainer panel 11, are required to be joined together, which increases the cost and the number of assembly work. There was a problem with the opening area of trunk-through vehicles being narrowed.

<Means for Solving the Problems> The present invention provides an upper back structure that improves the above-mentioned conventional problems, and is characterized by a downward U-shaped bend at the front end of the upper back panel. An edge is formed in the vehicle width direction, both left and right ends of this bent edge are connected to a rear spring support connected to the rear wheel house via a wheel house reinforcement, and a brace is attached to the bent edge of the upper back in the vehicle width direction. It penetrates and connects both left and right ends to the rear spring support, thereby connecting the brace and the upper back panel.

<Function> With the above configuration, the body rigidity between the left and right rear wheel houses is improved by the brace, and the movement of the rear suspension tower is absorbed, thereby improving all of the maneuverability, stability, and riding comfort. It has also become possible to expand the area of the opening for trunk-through vehicles.

<Example> An example of the present invention will be described below based on FIGS. 1 and 2. In FIG. 1, 1 is an upper back panel, 4 is a rear wheel house, 5 is a rear spring support, and 6 is a wheel house reinforcement.

In the present invention, the bottom surface of the downward U-shaped bent edge 2 formed in the vehicle width direction at the front end of the top back panel is left open downward without being joined to the top back clean force. A brace 12 is passed through this bent edge 2 in the vehicle width direction and both ends thereof are connected to the rear spring support 5, and the brace 12 and the upper back panel 1 are connected.

Rear spring support 5 of the brace 12
In addition, the connection means to the attachment back panel 1 is a second
As shown in the figure, first brackets 13 are fixed to both ends of the brace 12, and second brackets 14 are fixed to arbitrary positions on the axis of the brace 12, and as shown in FIG. The second bracket 14 is connected to the spring support 5, and the second bracket 14 is connected to the upper back panel 1.

Since the present invention has the above-mentioned structure, the strength between the rear wheel houses 4 in the upper back part is determined by the bending edge 2 at the front end of the upper back panel 1, the brace 12, and the second bracket 1 on the brace 12.
It is held by the upper back panel 1 which is connected at 4, and the rigidity is significantly improved. This brace 12
Due to the improved rigidity, the conventional reinforcement of the top cross member 9, the gusset foil house 10, and the strainer panel 11 using reinforcing members becomes unnecessary.
Furthermore, by connecting the upper ends of the rear spring support 5, that is, the suspension tower, with the brace 12, movement of the suspension tower is absorbed, and maneuverability, stability, and riding comfort are all improved.

<Effects of the invention> As described above, according to the invention, a brace is passed through the downward U-shaped bent edge formed in the vehicle width direction at the front end of the upper back panel, and both ends of the brace are connected to the rear spring support. A simple structure in which the shaft of the brace is connected to the atsupa back panel significantly improves the rigidity of the joint between the atsupa back and the rear wheel house, compared to the conventional atsupa cross member, gusset wheel house, and strainer panel. This eliminates the need for members, reduces costs, and expands the opening area for trunk-through vehicles. In addition, since the brace absorbs the movement of the suspension tower, maneuverability, stability, and ride comfort are all improved. Since it is penetrated through the trunk, it is not exposed to the outside and has the effect of making the trunk through opening look good.
