Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to the front structure of an automobile body.

BACKGROUND TECHNOLOGY At the very front end of an engine room formed in the front part of an automobile body, left and right radiator panel sides are joined and fixed to the front end edges of left and right foil aprons that constitute the left and right side walls of the engine room. The left and right radiator panel sides are connected at the top and bottom by radiator panel tops and front cross members, respectively.
Normally, the radiator for engine cooling water cooling and the condenser for the air conditioner are installed in the space surrounded by the left and right radiator panel sides, radiator panel tops, and front cross member. (For example, in 1987-
(Refer to Publication No. 92067).

Problems that the invention aims to solve: As shown in Figures 3 to 5, the front end of a conventional automobile body is bonded and fixed along the lower edges of the left and right wheel aprons A that constitute the left and right side walls of the engine room. The front ends of the left and right side frames B are extended to the inner surfaces of the left and right radiator panel sides C fixed to the front edge of the foil apron A, and a flange B' bent at the front end of the side frame B is attached to the radiator panel side C. Since it has a structure that is bonded and fixed to the inner surface of the panel side C, the side frame B protrudes into the space where the heat exchanger D such as a radiator or condenser is to be installed, and as shown in Figure 5, the side frame B protrudes into the space where the heat exchanger D such as a radiator or condenser is installed. The width of the heat exchanger D has to be narrowed by the protrusion of the side frame B, which poses a problem in that the capacity of the heat exchanger D, such as a radiator or a condenser, is limited accordingly. In FIG. 3, E is a radiator panel upper, and F is a front cross member having a box-shaped cross section.

The object of the present invention is to provide a vehicle body front structure that can solve the conventional problems as described above.

Means for Solving the Problems The present invention is configured such that the front end of the side frame, which is bonded and fixed to the foil apron, faces the radiator panel side, which is bonded and fixed to the front edge of the foil apron, at a predetermined distance rearward. In addition, a gusset is provided to firmly connect the radiator panel side and the side frame, and a space is formed between the radiator panel side and the front end of the side frame in which the side part of the heat exchanger can be accommodated. It is something.

Effect: As a result of the above, the side portions of the heat exchanger do not interfere with the side frames at all, making it possible to sufficiently increase the capacity of the heat exchanger and improving the performance of the heat exchanger.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 and 2.

In Figures 1 and 2, 1 is a foil apron that constitutes the left and right side walls of the engine room, 2 is a side frame that is bonded and fixed to the inner surface of the foil apron 1 almost along the lower edge, and 3 is a left and right foil apron. The left and right radiator panel sides 3 are connected at their upper parts by radiator panel tops (not shown), and their lower parts are connected to a front cross member having a box-shaped cross section. A heat exchanger 5 such as a radiator for cooling engine cooling water or a condenser for an air conditioner is disposed in a space surrounded by the left and right radiator panel sides 3, radiator panel tops, and front cross member 4. be done.

As shown in the figure, the radiator panel side 3 has a structure in which a portion 3a on the vehicle center side protrudes forward by a dimension d corresponding to the thickness of the heat exchanger 5 from the joint fixed portion with the front edge 1a of the foil apron 1. It is formed.

The front end flange 2a of the side frame 2 is flush with the front end edge 1a of the foil apron 1, and the side frame 2 and the radiator panel side 3 are firmly connected by a gusset 6.

That is, the gusset 6 has a vertical surface 6a that is fixed to the front edge 1a of the foil apron 1 and the front end flange 2a of the side frame 2, and a front cross member 4 that is bent forward from the lower end of the vertical surface 6a.
It is integrally formed in a shape having a horizontal surface 6b bonded and fixed to the upper surface, and a side flange surface 6c and a front flange surface 6d bent downward from one side end and front end of the horizontal surface 6b, respectively, One end of the vertical surface 6a is sandwiched between the front edge 1a of the foil apron 1 and the radiator panel side 3 and fixed by spot welding or the like, and is joined to the front end flange 2a of the side frame 2 by spot welding or the like. The horizontal surface 6b is joined to the upper surface of the front cross member 4 and fixed by spot welding or the like, and the side flange surface 6c is joined to the lower part of the vertical surface 3b of the radiator panel side 3 and fixed by spot welding or the like. Also, front flange surface 6
d is sandwiched between the 3a portion of the radiator panel side 3 and the front surface of the front cross member 4 and fixed to both by spot welding or the like, thereby forming the foil apron 1, the side frame 2, the radiator panel side 3 and the front cross member 4. The gusset 6 firmly connects the front cross member 4 to the radiator panel side 3, and the side part of the heat exchanger 5 is connected to the 3a portion of the radiator panel side 3 and the vertical surface 6a of the gusset 6 located rearward by the distance d. Ample storage space is provided.

Effects of the invention According to the invention configured as described above, the front end of the side frame is not directly bonded and fixed to the radiator panel side, but is moved rearward from the radiator panel side by a predetermined dimension corresponding to the thickness of the radiator or capacitor. By adopting a structure in which the front end of the side frame and the radiator panel side are firmly connected with a gusset, a heat exchanger such as a radiator or a condenser can be installed between the radiator panel side and the front end of the side frame behind it. A space is formed in which the side part of the heat exchanger can be accommodated, and the inconvenience of the side part of the heat exchanger interfering with the side frame is completely eliminated, making it possible to secure the maximum capacity of the heat exchanger. In addition, in the past, it was necessary to provide a notch on the side of the heat exchanger as shown in Figure 5 to avoid interference with the side frame, but with this invention, this is no longer necessary and the radiator, condenser, etc. It is possible to reduce the manufacturing cost of heat exchangers such as the above and improve the performance of the heat exchanger, and it can bring about a great practical effect.
