Abstract

PURPOSE:To make the setting of a fuel tank ever so simple, by engaging a hook part of a supporting band with an opening part of a fixed bracket at the body side, and attaching the setting bracket set tight to somewhere short of the hook part tightly to a tank setting surface of the fixed bracket. CONSTITUTION:One end of a fixed bracket 1 is tightly attached to a floor panel 7 while the other end to a rear end panel 9, respectively. In addition, an opening part 11 is formed in a vertical surface 3 of the fixed bracket 1, while a nut 13 is installed on a tank setting surface 5, and this nut is screwed in a thread part 19 of the bolt 17 pierced through a bolt hole 15a of a setting bracket 15. On the other hand, in this setting bracket 15, there are provided with a coupling surface 21a to be joined with a horizontal surface of the fixed bracket 1 by the bolt 17 and a setting surface 23 being bent from this coupling surface 21a. In addition, an end part of a metallic supporting band 29 supporting a body 27 of a fuel tank 25 is tightly attached to this setting surface 23, and furthermore a hook part 31 to be engaged with an opening part 11 is installed in the end part of the supporting band 29.

Description

[Detailed description of the invention] [Industrial application field] This invention relates to a fuel tank mounting device.

[Prior Art] Conventionally, in a type of band attachment for attaching a fuel tank using a band, an end of a support band 103 is fixed to a fixing bracket 101 fixed to the vehicle body, as shown in FIGS. 3 to 4, for example. The mounting structure is such that a bracket 105 is engaged with a bolt 107 to support a tank body 109.

This type of conventional technology is described in Sankaido Edition Automotive Engineering Complete Book, Volume 13.
Detailed information is provided in ``Passenger Car Body''.

[Problem to be Solved by the Invention 1] In this structure, the procedure for installing the tank body 109 is as follows: Loosen the bolt 107 screwed into the fixing bracket 101 and let the head 111 of the bolt 107 protrude by a predetermined amount. Next, for installation, the bracket hole 113 of the bracket 105 is hooked onto the head 111 of the bolt 107 for temporary support, and then the bolt 107 is fully tightened.

In other words, temporary support is provided before final tightening to ensure workability. For this reason, when mounting with bolts, the bracket hole 113 of the bracket 105 has a first opening 115 larger in diameter than the head 111 of the bolt 107 and a second opening 119 that is approximately the same diameter as the threaded part 117. is formed.

Therefore, the first opening 115 is connected to the head 11 of the bolt 107.
1, then insert the second opening 119 into the threaded part 117Il.
! By moving it to +1, temporary support can be performed, but in this case, if the protrusion IH of the head 111 of the bolt 107 is too small, a problem will occur in which the bracket hole 113 cannot be inserted. In addition, if the protrusion IH is too large, there may be a risk that the threaded part 117 will not be able to engage properly and fall off, so the protrusion amount H must be set at the best position, which is cumbersome. This was not desirable in terms of workability. Furthermore, the mounting of the bracket hole 113 having the first opening 115 larger than the head 111 of the bolt 107 has the problem of becoming thicker and larger, which leads to a decrease in strength.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a fuel tank mounting device which is not only capable of improving workability but is also desirable in terms of strength.

[Means for Solving the Problems] In order to achieve the above object, in the present invention, an opening and a tank mounting surface are provided in the fixing bracket on the vehicle body side, and the opening and the tank mounting surface are provided at the end of the support band. A hook part is provided that engages with each other in a detachable manner, and a bracket is fixed in front of the hook part, and the bracket is bolted to the tank mounting surface of the fixing bracket to support the tank body. . In a preferred embodiment, the lower side of the opening is formed at least in the shape of a hook of the hook portion.

[Operation] In such a mounting device, the hook portion is hooked onto the opening. At this time, the hook portion properly engages with the lower side of the opening, and the support band and mounting bracket are temporarily supported while being positioned relative to the fixed bracket. Next, for installation in a temporarily supported state, the bracket is fixedly connected to the tank mounting surface of the fixed bracket 1- by screwing bolts into the tank mounting surface.

[Example 1] Hereinafter, an example of the present invention will be described in detail with reference to FIGS. 1 and 2.

In the figure, reference numeral 1 designates a fixed bracket having a vertical surface 3 and a horizontal surface 5, one end of which is fixed to a floor panel 7, and the other end to a rear end panel 9. An opening 11 is formed in the vertical surface 3 of the fixing bracket 1, and the lower side 11a of the opening 11 is set smaller than the upper side 11b. Further, a nut 13 is provided on the horizontal surface 5 serving as a tank mounting surface, and the nut 13 is mounted by screwing a threaded portion 19 of a bolt 17 passing through a bolt hole 15a of a bracket 15.

Mounting (The bracket 15 has a coupling surface 21 that is coupled to the horizontal surface 5 of the fixed bracket 1 by the bolt 17, and a mounting surface 23 that is bent from the coupling surface 21.
3, an end portion of a metal support band 29 that supported the tank body 27 of the fuel tank 25 is fixed.

Furthermore, a hook portion 31 is provided at the end of the support band 29 and engages with the frontage portion 11 in a manner that allows the hook portion 31 to be freely engaged with the frontage portion 11 . The hook portion 31 is made of metal and is formed into a tongue shape by extending the end of the support band 29 and folding the extended end back briefly.

The hook part 31 is located at the lower side 11 of the opening 11.
The dimension a is set to be almost the same as the dimension a.

In addition, the length b of the hook portion 31 is such that when the bracket 15 is fastened with the bolt 4, the tip is at the upper side 1'1 of the opening 11.
The dimensions are set so that a slight play gap is created with respect to b.

In the mounting device configured in this way, the mounting procedure will be described as follows: hook portions 31 provided on the two support bands are hooked onto the opening 11 of the fixing bracket 1. This hook can be easily hooked because the upper side 111) side of the frontage portion 11 has a large frontage. At this time, hook part 3
1 engages with the lower side 11a of the opening 11, so the two support bands and the mounting bracket 15 are temporarily supported while being positioned slightly apart from the fixed bracket 1.

Next, one threaded portion of the bolt 17 passing through the bolt hole 15a of the mounting bracket 15 is screwed into the oak 1-13, so that the mounting bracket 15 rises together with the hook portion 31. Finally, it comes to be coupled and fixed to the horizontal surface 5.

[Effects of the Invention] As described above, according to the fuel tank mounting device of the present invention, temporary support can be performed with a single touch, and therefore workability is greatly improved. Furthermore, the mounting bracket does not lose its mounting strength and can be made smaller.
