Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a heavy body structure of an automobile to which a fender mirror is attached.

[Prior Art] Conventionally, as a structure of a car body in which a 7-end mirror is attached to a front fender panel, for example,
The one described in Japanese Patent No. 25872 is known.

That is, as shown in FIG. 5, the front fender panel 101
A mirror support plate 103 is provided inside the mirror support plate 1.
The attachment part 107 of the fender mirror 105 is passed through the overlapping area of the fender mirror 103 and the front fender panel 101 in a negative manner, and a nut 109 is screwed into the threaded part of the attachment part 107 passing through from the back side to secure the fender mirror 105 in place.

[Problems to be Solved by the Invention] As described above, the fender mirror 105 is fixed by screwing the nut 109 onto the mounting portion 107.
Since this work is performed from the back side of the front fender panel 101, a work space open to the inside is required.

However, inside the front fender panel 101,
Although a reinforcing panel 111 (hood ledge reinforcement) is provided to ensure the rigidity of the front fender panel 101, the reinforcing panel 111 is omitted from the attachment area of the fender mirror 105 in order to secure a working space.

For this reason, countermeasures such as partially increasing the thickness of each panel are required to cover areas with weak rigidity.
This was not desirable in terms of workability and cost.

Therefore, an object of the present invention is to provide a vehicle body structure for a JRJJ that can ensure rigidity up to the fender mirror mounting area with a reinforcing panel, and also prevents any hindrance to the installation work of the fender mirror mounting part. It is said that

[Means for Solving the Problems] In order to accomplish the above object, the present invention provides a mirror mounting hole on the inside of the front fender panel, which is fixed to the hood ledge panel and whose front end is connected to the mirror mounting hole of the front fender panel. A reinforcing panel is provided that extends to the area, and the reinforcing panel is provided with a working hole that passes through the upper and lower sides and faces the mirror mounting hole, and the mounting portion of the fender mirror that passes through the mirror mounting hole is exposed to the working hole. At the same time, the mounting part is fixed to the front fender panel.

[Function] In this vehicle body structure, the installation procedure is explained as follows: The mounting portion of the fender mirror is penetrated through the mirror mounting hole. Next, the fender mirror can be attached by fixing the attachment portion facing the working hole to the front fender panel from the back side of the panel. Since this installation is sometimes done through the work hole, there is no problem with the work. Further, the reinforcement panel makes it possible to ensure rigidity up to the fender mirror mounting area 85.

[Embodiment] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings of FIGS. 1 to 4.

In the figure, 1 indicates a radiator core support panel in front of the engine room 3, and 5 indicates a hood ledge panel on the side of the engine room 3. The hood ledge panel 5 is provided with a strut housing 7.

One end flange 11 of the front fender panel 9 is superimposed on the upper flange 5b of the hood ledge panel 5 and connected with bolts 4 and nuts 42, and the other end is a free end.

Inside the front fender panel 9 are a top surface 13 and a side surface 1.
A reinforcing panel 17 (hood ledge reinforcement) having a channel-like cross section and consisting of a lower surface 15 and a lower surface 15 is disposed, and an upper end flange 178 of the reinforcing panel 17 overlaps with the upper rising flange 5a of the hood ledge panel 5. The lower end flange 17b is coupled and fixed to the general surface of the hood ledge panel 5.

The front end of the reinforcing panel 17 extends to the area of the mirror attachment hole 21 of the fender mirror 19 attached to the front fender panel 9. Rigidity is ensured around the mirror mounting hole 21 by a base plate 23 provided on the back side of the front fender panel 9.

On the upper surface 13 and lower surface 15 of the reinforcing panel 17, there are working holes 13 that vertically penetrate through the portions facing the mirror mounting holes 21.
a.15a is provided, and the diameter of each working hole 13a, 15a is set to a size that allows the tool 25 etc. to be inserted with sufficient margin.

On the other hand, the mounting portion 27 of the fender mirror 19 is formed in a round shape, and the lower end portion of the mounting portion 27 extends from the mirror mounting hole 21 to the inner space of the reinforcing panel 17 via the working hole 13a of the soil surface 130.

A nut 29 is screwed into the threaded portion 27a at the lower end, and a mounting spring 31 is interposed between the nut 29 and the front flap 9.

As a result, by tightening the nut 29, the mounting spring 3
1 becomes stronger, and the base 19 of the fender mirror 19
a are in strong contact with the front fender panel 9.

In such a structure, when an external force is applied to the fender mirror 19 from the outside, the fender mirror 19 falls down using the base 19a as a fulcrum, and after the external force is removed, it returns to its original position due to the elastic action of the compressed mounting spring 31. It is now back to its current state.

Therefore, the fender mirror 19 itself is not destroyed by external force, and pedestrians can
Even when hitting a 9, the attack on pedestrians will be alleviated.
