Description

[Detailed Description of the Invention] This invention relates to a mounting structure for a reservoir tank for a radiator.

As a conventional mounting structure for a reservoir tank for a radiator, for example, there is a structure as shown in FIG.

The mounting structure of this radiator reservoir tank is such that the reservoir tank 1 is fixed by fixing the mounting parts 2, 2 integrally formed on both sides of the reservoir tank 1 to the mounting panel 3 on the vehicle body side with screws 4.4. ing.

However, in such a conventional mounting structure for a reservoir tank for a radiator, since the reservoir tank 1 is cantilever-supported by the mounting parts 2, 2 on both sides, the center of gravity G of the reservoir tank 1 is at the mounting position. Because the tank was overhanging further apart, when inputs such as vibrations from the engine or other sources were applied, the reservoir tank would vibrate and excessive force would be applied to the mounting section, making it impossible to maintain sufficient strength by supporting only the mounting section. This means that during installation, the reservoir tank must be supported by hand while securing the mounting portion.

The present invention was developed with the above points in mind.The reservoir tank is equipped with vertical guide grooves and a protruding step extending over the entire lower part, and the mounting panel is equipped with a mounting plate for receiving the bottom of the reservoir tank. a mounting part, and a bracket that engages the guide groove and the protruding stepped part, respectively, and in addition to being supported by the mounting part of the reservoir tank, the bottom part of the reservoir tank is received and supported by the mounting panel, and the bracket is provided on the mounting panel. To solve the above-mentioned problems by guiding the guide groove and the protruding step part of the reservoir tank to facilitate the installation of the reservoir tank, and by making it possible to freely position the mounting part of the reservoir tank with respect to the mounting panel. It is an object.

This invention will be explained below based on the drawings.

FIGS. 2 to 4 are diagrams showing two embodiments of this invention.

First, the configuration will be described. Reference numeral 10 denotes a reservoir tank, and this reservoir tank 10 is supported and fixed by a mounting panel 11 and a bracket 12 on the vehicle body side.

The reservoir tank 10 has mounting portions 13° 13 integrally formed on both sides of the upper side of the mounting panel 11 side, and these mounting portions 13, 13 are attached to the mounting panel 11 with screws 14° 14.
It can be fixed freely.

In the side portion 15 at the other side of the attachment portions 13, 13, a guide groove 16 extending in the vertical direction is formed in the center portion, and a protruding step portion 17 is formed over the entire lower portion.

Further, the bottom portion 18 is provided with an outwardly protruding portion 19 approximately in the center thereof (FIGS. 3 and 4).

The reservoir tank 10 is made of synthetic resin and is slightly deformable.

The mounting panel 11 has a bent shape including a vertical portion 20 for fixing the mounting portion 13 of the reservoir tank 10 and a mounting portion 21 that is continuous with the vertical portion 20 and receives the bottom portion 18 of the reservoir tank 10. Ridge can be adopted.

The bracket 12 works together with the mounting panel 11 to tightly fix the lower part of the reservoir tank 10, and is previously welded to the mounting panel 11 on the side 15 side of the reservoir tank 10.
Bent portion 2 at the tip that can be brought into close contact with the upper surface 23 of the protruding step portion 17
2.

Further, this bent portion 22 is formed with a protrusion 24 that engages with the guide groove 16 of the reservoir tank 10.

Next, the effect will be explained.

First, place the reservoir tank 10 so that the protruding step part 17 is on the lower side.
is made oblique so that the upper surface 23 of the protruding step portion 17 comes into contact with the bent portion 22 of the bracket 12, and the guide groove 16 is engaged with the protrusion 24.

Next, when the upper part of the reservoir tank 10 is rotated in the direction of the vertical part 20 of the mounting panel 11, the guide groove 16 aligns with the protrusion 24.
Then, the upper surface 23 of the protruding step part 17 is the bent part 22, and the protruding step part 17 is guided by the bent part 22 of the bracket 12.
At the same time, the bottom part 18 comes into contact with the mounting part 21, and the lower part of the reservoir tank 10 is tightly fixed.

In this case, due to the presence of the convex portion 19 provided on the bottom portion 18, upward pressure is applied to force the bottom portion 18 to deform, and the close fixation becomes strong (FIGS. 3 and 4).

In addition, since the reservoir tank 10 is positioned by the engagement relationship between the guide groove 16 and the protrusion 24, the mounting portion 13.13 (7
) When mounting on the panel 11, alignment is ensured.

In this state, if the mounting part 13.13 is fixed to the mounting panel 11 with the screws 14, the upper part is fixed by the mounting part 13.13, the bottom part 18 is received and supported by the mounting panel 11, and further the bracket 12 and the mounting panel are fixed. This allows the lower part to be tightly fixed by the holder 11, and can be mounted with sufficient strength against input.

As explained above, according to this invention, the reservoir tank for a radiator can be mounted by fixing the reservoir tank to the mounting panel on the vehicle body side via the mounting part integrally formed on one side of the reservoir tank. In the structure, the reservoir tank has a guide groove extending vertically in the center of the side on the other side of the mounting part, and a protruding stepped part across the entire lower part, and the mounting panel includes: A mounting part that supports the bottom of the reservoir tank, and a bent part whose tip can be brought into close contact with the upper surface of the protruding stepped part of the reservoir tank, and a protrusion that engages with the guide groove of the reservoir tank. and when installing the reservoir tank, the guide groove of the reservoir tank, which is slanted with the protruding stepped portion facing downward, is engaged with the protruding portion of the bracket, and the protruding stepped portion of the reservoir tank is The protruding step part of the reservoir tank, which is rotatably mounted without abutting the top surface of the bracket against the bent part of the bracket, is pressed and held by the bracket, and the bottom of the reservoir tank is received and supported by the mounting part of the mounting panel. At the same time, the mounting part of the reservoir tank can be positioned freely with respect to the mounting panel, which eliminates overhang and reduces the load on the mounting part compared to conventional systems in which the reservoir tank is fixed and supported only by the mounting part. This has the effect that it is possible to prevent excessive force from being applied to the mounting portion, and that a strong mounting condition can be easily obtained by mounting the bracket.

Further, by providing a vertical guide groove in the reservoir tank and forming a protrusion on the bracket that engages with the guide groove, the mounting portion can be positioned extremely easily, and the installation work efficiency is improved.

Moreover, by forming a protruding step on the reservoir tank and holding the protruding step by the bent part at the tip of the bracket, the degree of tightness and fixation is extremely high. It is extremely convenient because it does not require a special bracket because it can be used with those set for other parts.

The bracket is pre-installed on the mounting panel, and when installing the reservoir tank, the reservoir tank is tilted, the guide groove is engaged with the protrusion of the bracket, and the upper surface of the protruding stepped part is not brought into contact with the bent part of the bracket. Since it was decided to rotate the reservoir tank and then secure the mounting part with screws, it is extremely easy to position the mounting part at the same time as the reservoir tank is rotated and mounted, which has the effect of further improving the installation work efficiency. .
