Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a mounting structure for a protector that protects auxiliary equipment such as a fuel tank provided on the lower surface of a floor panel of a vehicle body.

(Prior Art) Various protectors for protecting auxiliary equipment have been proposed. As an example, as disclosed in Japanese Patent Application Laid-Open No. 59-57026, there is shown a cantilever support type protector in which one side of the protector is fixed to a cross member of a vehicle body with bolts. In addition to this, there are various types such as a double-sided support type in which both sides are fixed to the cross member with bolts in order to strengthen the support.

However, because the fixing structure is such that the heavy protector is fixed to the cross member with bolts while the worker is supporting the protector, there is a problem that the worker is burdened during the work and the work efficiency is poor. , improvements were desired.

(Problems to be solved by this invention) As mentioned above, this invention focuses on the problem of poor workability when bolting a heavy protector made of metal such as a steel plate to the mounting part of the vehicle body. By slightly changing the bolt holes of the protector, the flange in which the bolt holes are formed, and the mounting surface of the mounting part of the vehicle body, we aim to significantly improve workability and simultaneously improve safety during work. The present invention provides a mounting structure for a protector for protecting auxiliary equipment.

(Configuration to solve the problem) The configuration of the present invention to solve the above problem is that one side of the bolt holes provided in the pair of opposing mounting flanges of the protector is an open hole, and the other side is a daruma hole. In addition, the flange in which the daruma hole is formed and the mounting part of the vehicle body are sloped surfaces with the small hole side of the daruma hole facing upward, and the bolts are arranged perpendicular to the inclined surface of the mounting part of the car body. shall be.

(Effect of the invention) The effect of the invention with the above configuration is that the bolt screwed and fixed to the mounting part of the vehicle body can be easily fixed by inserting it into the bolt hole on one side formed in the flange of the protector. Since the other side is configured as a daruma hole, the protector can be temporarily placed against the vehicle body by simply inserting it into the bolt at the large hole side of the daruma hole and sliding it to the small hole side. There is no need to support the protector, which greatly improves work efficiency. In addition, the car body and flange are sloped as described above, and the bolts are placed perpendicular to the slope of the car body attachment part, so the temporary In the stored state, the action of the protector's own weight acts on the small hole side of the daruma hole, which eliminates the fear of the bolt and the daruma hole becoming disengaged due to vibration, etc. This has the effect of simultaneously improving safety.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to FIGS. 1 to 4 of the drawings.

A plurality of cross members 2, 3 are provided between the frames 1, 1, which are arranged at a predetermined interval in the longitudinal direction of the vehicle body, and extend in the width direction and are firmly fixed to the frames 1, 1 by means such as welding. A fuel tank 4 is attached to the cross members 2, 3 and the frames 1, 1.
In addition, auxiliary equipment such as a muffler (not shown) is firmly fixed by appropriate means.

Further, a metal protector 5 for protecting the fuel tank 4 from flying stones and the like is firmly connected and fixed to the cross members 2 and 3 at a pair of opposing side ends by bolts 6.

Next, the detailed structure of this protector will be explained.

The protector 5 is fixed to the cross members 2 and 3 by bolts 6 through bolt holes formed in a front flange 7 and a rear flange 8, respectively, which are provided in the longitudinal direction of the vehicle body. As shown in FIG. 4, the bolt hole provided in the rear flange 8 is an open hole 9a, and the bolt hole provided in the front flange 7 is composed of a round hole 10 and a normal round hole 11. are doing. Moreover, this front side flange 7 is connected to the small hole 10 of the Daruma hole 10.
The cross member 2 is configured as an inclined surface 12 with the a side facing upward, and an inclined surface 13 in the same direction is formed on the cross member 2 so as to correspond to this inclined surface 12.

Note that the bolt 6 that is screwed and fixed to the inclined surface 13 of the cross member 2 is arranged perpendicular to this inclined surface 13.

Here, the order in which the protector 5 is attached to the vehicle body will be explained in detail.

First, attach bolt 6 to cross member 3 using protector 5.
At the same time, only the bolts 6 corresponding to the above-mentioned daruma holes are temporarily fastened to the cross member 2, leaving a predetermined interval for insertion.

Next, insert the opening hole 9 of the protector 5 into the cross member 3.
Insert and secure the bolt 6 fixed to the
After this, the bolt 6 fixed to the cross member 2 is inserted into the large hole 10b of the daruma hole 10, and the small hole 10a is inserted.
By sliding the protector 5 to the side so that the bolt is engaged, the protector 5 is completely temporarily stored against the vehicle body, and the worker does not need to support the protector 5.

In this state, insert the bolt 6 into the cross member 2.
Since the protector 5 is disposed perpendicularly to the inclined surface 13 of the protector 5 and the front flange 7 is an inclined surface, the force exerted by the protector 5's own weight acts in the direction of connecting the bolt 6 and the small hole 10a. Therefore, the engagement force between the two becomes stronger, and the fear of the protector 5 falling off and getting damaged can be eliminated. Therefore, the operator can safely carry out the next work, which is the final tightening of the bolts 6.

As described above, in the present invention, the work of attaching the protector 5 to the vehicle body can be performed easily and safely.
