Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for a gas stay used in a flip-up back door.

In order to provide elasticity in the opening direction of the flip-up bank door, a gas stay containing, for example, nitrogen gas in a cylinder is attached and swung between the vehicle body and the back door.

The holding force when opening the back door is determined by the reaction force of the gas stay, but the pressure of the gas sealed in the cylinder changes depending on the outside temperature in summer and winter, and the door specifications differ depending on the door equipped with wipers etc. There is a problem that the opening degree of the bank door changes depending on the weight, making it difficult to use.For this reason, in the past, in order to maintain the opening degree of the back door, multiple gas stays with different reaction forces were prepared. The gas stay can be attached and detached and replaced as needed to obtain an appropriate door opening (-However, this replacement work is troublesome and not desirable in terms of parts management.

Therefore, the present invention has been developed in view of the above-mentioned conventional problems.By changing the mounting position of the gas stay mounting bracket in response to changes in outside temperature, door weight, etc., It was possible to obtain the opening degree,
The purpose of this invention is to provide a gas stay mounting structure for a flip-up back door.

The present invention will be described below with reference to illustrative embodiments.

The bracket 2 has a gas stay attachment hole 5 in the central protrusion 3. Attachment pieces 1, 1' are provided on both sides of the gas stay attachment hole 50.
The mounting pieces 1 and 1' are provided with locking holes 8 and 8', and one end of the gas stay 4 that connects the vehicle body 6 and the back door T is pivotally attached to the gas stay mounting hole 5. has been done.

The locking hole 8 (or 8') of one of the mounting pieces 1 (or 1') of the bracket 2 is engaged with the mounting surface of the vehicle body 6 and the back door I to which the mounting pieces 1, 1' of the bracket 2 are attached. A center mounting hole (not shown) is provided for stopping the bracket 2, and the distance between the center mounting hole and the center mounting hole is the same as that of the bracket 2.
A first mounting hole (not shown) and a second mounting hole 9 are formed at symmetrical positions on both sides of the central mounting hole so as to coincide between the two locking holes 8° and 8'.

With the above configuration, one mounting piece 1 (or 1') of the bracket 2 is attached to the central mounting hole formed on the vehicle body 6 and the bank door IO mounting surface, and the other mounting piece 1' (or 1) is attached to the central mounting hole on the mounting surface. By attaching it to either the first attachment hole or the second attachment hole 9, an appropriate degree of opening of the door can be obtained.

Figure 2 shows the installation state of the gas stay 4 in response to changes in outside temperature.The solid line shows the installation state when the outside temperature is low, such as in winter. It is attached to the center attachment hole and the first attachment hole of the back door 7 with bolts 10 and nuts 11.

Also, the two-dot chain line shows the installation state when the outside temperature is high such as in summer, and as the outside temperature rises, the gas pressure sealed in the cylinder 12 expands and the piston rod 13 expands. Therefore, the mounting position of the gas stay 40 has been changed.

To change the above mounting position, remove the bolt 10 on the other mounting piece 1 side of the bracket 2 attached to the first mounting hole on the mounting surface of the vehicle body 6 and back door 7, and loosen the bolt 10 on the center mounting hole side. Place bracket 2 at 180mm centering on the center mounting hole.
217) Align the locking hole 8 drilled in the other mounting piece 1 with the second mounting hole 9 drilled in the mounting surface of the vehicle body 6 and back door 7, and tighten with the bolt 10 and nut 11. At the same time, increase the number of bolts 10 in the center mounting hole.

In the embodiment shown in FIG. 2, the vehicle body 6 side and the back door I
Although the state in which both sides have been moved is shown by the two-dot chain line, either one can be moved and adjusted as appropriate depending on the state of the outside temperature.

Furthermore, in the above embodiment, the center of the bracket 2 on which the gas stay 4 is pivotally mounted has a shaped cross section, and even if the bracket 2 is rotated around the gas stay mounting hole 5, it will not interfere with the cylinder 12 or piston rod 13 of the gas stay 4. However, the present invention is not limited to this, and for example, the bracket may be formed into a flat plate, and embossing may be provided on the vehicle body and back door side to which the bracket is attached.

In this case, all you need to do is remove the bolts attached to both sides of the bracket, move the mounting holes, and then install the bolts.

Furthermore, the portion of the gas stay main body that is pivotally attached to the bracket may be made longer to prevent interference with the bracket.

As described above, according to the present invention, the bolts attached to the mounting pieces extending on both sides of the bracket with the gas stay pivoted in the center can be removed, and the bolts attached to the first or second mounting holes can be removed. , loosen the bolt installed in the center mounting hole,
Rotate the bracket 180 degrees around the central mounting hole, and align the locking hole of the other mounting piece with the second mounting hole or the first mounting hole.
By simply fixing the door with bolts that match the mounting holes, you can easily obtain the appropriate door opening even if the internal pressure changes due to the outside temperature of the gas stay or the weight changes due to differences in door specifications.

In addition, according to the present invention, it is possible to fix the bracket by rotating it, so the assembly work is easy. Since there is no need to provide multiple parts with different reaction forces, parts management is easy.

Furthermore, the bracket according to the present invention can be used for both the vehicle body side and the door side, so the number of parts can be reduced, and since the gas stay can be pivotally mounted on the protruding part of the bracket, even when the bracket is rotated, the gas stay remains unchanged. This has the effect of not interfering with the cylinder or rond.
