Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a fixing structure for reliably maintaining the closed state of an opening/closing body such as a door in an automobile, for example.

[Conventional technology]

Conventionally, opening/closing bodies such as side sliding doors and rear back doors have been attached to the body of automobiles so that they can be opened and closed freely.In order to ensure that these opening/closing bodies remain closed when closed, so-called locking functions have been installed. A fixed member is provided separately from the door lock mechanism.

This fixing structure is explained by taking a sliding door on the side of the vehicle body as an example. As shown in FIG.
0 is fixed and the sliding door 30
Concave female hooks 20 that fit into the mail hooks 10 are fixed to the top and bottom of the sides.

When the sliding door 30 is closed, the fourth
As shown in the figure, the protrusion 11 of the mail hook 10
0 and the recess 210 of the female hook 20 fit together, thereby holding the sliding door 30 in a closed state, that is, fixing it.

Note that reference numeral 70 in FIG. 4 is a fastening member for fixing the mail hook 10 and the female hook 20 to the vehicle body 60 and the sliding door 30, respectively.

Further, in order to absorb shock and suppress generation of abnormal noise such as impact noise when the mail hook 10 and the female hook 20 are fitted together, rubber 80 or the like is coated on the surface of the convex portion 110 of the mail hook 10. It is covered.

Further, a locking mechanism consisting of a striker, a catch, etc. (not shown) is fixed to substantially central portions of the sliding door 30 and the vehicle body 60 in the vertical direction, which are opposed to each other.
The sliding door 30 is supported by three fitting parts of the sliding door 30 and the female hook 20, and rollers in the slide rails provided above and below.

In addition, as a conventional technology showing a fixing structure by fitting a mail hook and a female hook in such a sliding door, for example,
There is Publication No. 39923 (Utility Application No. 49-113429), as well as Publication No. 166621 (Utility Application No. 60-16662)
No. 59-54730), there is a similar fitting fixing structure in a back door, with a cushion body interposed in the fitting portion.

[The problem that the idea attempts to solve]

However, in the case of the structure in which the opening/closing body is fixed when closed as shown in FIGS. 4 and 5, due to torsion and vibration of the vehicle body,
The vehicle body 60 and the sliding door 30 may move relative to each other, and when such a phenomenon occurs, the mail hook 10 and the female hook 20, which are fitted together to hold the sliding door 30 in a closed state, generate frictional noise. This causes discomfort to the occupants inside the vehicle.

Further, as shown in FIG. 4, the surface of the convex portion 110 of the mail hook 10 is coated with rubber 80 for cushioning and preventing the generation of abnormal noise.
No. 0 is a thin-walled material, and it is not possible to sufficiently prevent the generation of frictional noise in the fitted state as described above, and the thin-walled rubber 80 is damaged due to the large force exerted during fitting and fitting. There is a risk that the generation of the friction noise may become noticeable.

Furthermore, it is not possible to ensure sufficient sealing between the mail hook 10 and the female hook 20 when they are fitted, and abnormal noises such as impact sounds generated during the fitting may enter the vehicle interior.

Therefore, the purpose of this invention is to prevent the generation of frictional noise between the mail hook and female hook when they are in the fitted state when relative movement occurs between the vehicle body and the opening/closing body, and to improve the sealing performance when they are fitted. be.

[Means to solve the problem]

Therefore, this invention solves the above-mentioned problem by sealing a lubricant in the convex part of the mail hook made of impregnated sintered alloy, keeping the surface of the convex part always lubricated, and
This problem is attempted to be solved by performing a seal during fitting with a sealing material provided on the outer periphery of the female hook.

Further, to explain in detail with the reference numerals shown in FIG. 1, the fixing that maintains the closed state of the opening/closing body 3 such as a door is achieved by fitting the convex mail hook 1 and the concave female hook 2. In the structure, the mail hook 1 is formed of an impregnated sintered alloy, and a lubricant 4 such as grease is provided in the convex portion 11 of the mail hook 1.
At the same time, a sealing material 5 is provided on the outer periphery of the female hook 2, which comes into elastic contact with the male hook 1 when the female hook 1 is fitted into the female hook 2.

[Effect]

According to the above-mentioned means, the mail hook 1 is formed of an impregnated sintered alloy, and the lubricant 4 is sealed in the convex part 11, so that the lubricant 4 penetrates the convex part 11. Therefore, even if there is a relative movement between the vehicle body 6 and the opening/closing body 3 when the female hook 2 is engaged with the recess 21, the female hook 1 and the female hook can be kept in a lubricated state at all times. It is possible to reliably prevent the occurrence of frictional noise with 2.

In addition, in this fitted state, the sealing material 5 provided on the outer periphery of the female hook 2 is attached to the female hook 1.
Since both members 1 and 2 can be reliably sealed by coming into elastic contact with, it is possible to prevent abnormal noises such as impact sounds from entering the vehicle interior and muddy water from entering the vehicle interior.

〔Example〕

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

The drawings from Fig. 1 to Fig. 3 show an embodiment of this invention, in which Fig. 1 is a longitudinal cross-sectional view when the fixing member for holding the closed state when opening and closing is fitted, and Fig. 2 is a longitudinal sectional view when the fixing member is fitted.
3 and 3 are schematic front views of a mail hook and a female hook, which are fixing members fixed to the vehicle body side and the opening/closing body side, respectively.

For example, to explain the fixing structure of a sliding door on the side of a vehicle body, as shown in FIG. A concave female hook 2 having a concave portion 21 that fits into the convex portion 11 of the mail hook 1 is fixed on the sliding door 3 side with a fastening member 7 such as a bolt. When the mail hook 1 is closed, the protrusion 1 of the mail hook 1 as shown in FIG.
1 and the recess 21 of the female hook 2, the slide door 3 is held in the closed state, that is, fixed in the closed state.

In the fixing structure when the opening/closing body is closed, the mail hook 1 is fixed to the vehicle body 6 side as shown in FIGS. The mail hook 1 is formed of an impregnated sintered alloy, and the protrusion 11 of the mail hook 1 formed of the impregnated sintered alloy is filled with a lubricant 4 such as grease to prevent leakage to the outside with a seal member 8, for example. It is enclosed in such a way that it does not. Incidentally, this sealing member 8 is used as appropriate as necessary.
It is also possible to omit the sealing member 8 and simply fix the mail hook 1 with the lubricant 4 sealed in the convex portion 11 to the vehicle body 6 using the fastening member 7.

The lubricant 4 sealed in the convex portion 11 of the mail hook 1 penetrates into the convex portion 11 made of impregnated sintered alloy and oozes out onto the surface, keeping this surface in a constant lubricated state. This is something that can be done.

Further, as shown in FIGS. 1 and 3, the female hook 2 provided with a recess 21 into which the protrusion 11 of the mail hook 1 fits is made of resin or metal such as plastic and oil-impregnated plastic, The entire outer periphery of the female hook 2 (see FIG. 3) is covered with rubber that elastically contacts the entire outer periphery of the female hook 1 to perform a sealing action when the female hook 1 is fitted with the female hook 1, as shown in FIG. The female hook 2 constructed in this manner is fixed to the sliding door 3 by a fastening member 7.

Therefore, when the mail hook 1 and the female hook 2 are fitted together when the sliding door 3 is closed,
The lubricant 4 oozes out on the surface of the convex portion 11 of the mail hook 1 and is in a lubricated state, and the concave portion 21 of the female hook 2 is in contact with the lubricated portion of the convex portion 11. , the vehicle body 6 and sliding door 3 due to torsion and vibration of the vehicle body, etc.
Even when relative movement occurs between the mail hook 1 and the female hook 2, the lubrication effect of the lubricant 4 that has permeated the convex portion 11 of the mail hook 1 prevents the generation of friction noise between the mail hook 1 and the female hook 2. This can be reliably prevented and will not cause any discomfort to the occupants inside the vehicle.

Incidentally, such a lubrication state is achieved by the lubricant 4 sealed in the convex portion 11 of the mail hook 1.
It is something that can be supplied and maintained for a long period of time.

Further, when the mail hook 1 and the female hook 2 are fitted together, the seal material 5 provided on the outer periphery of the female hook 2 comes into elastic contact with the outer periphery of the mail hook 1, so that the mail hook 1
The female hook 2 can be sealed off and sealed from the outside of the vehicle.

Therefore, it is possible to reliably prevent abnormal noises such as impact noises generated by the fitting action of the mail hook 1 and the female hook 2 during the closing operation of the sliding door 3 from being transmitted into the vehicle interior. It is possible to prevent muddy water and the like rolled up from untied tires from entering, and to reliably prevent this muddy water and the like from adhering to the mail hook 1 and the female hook 2.

Furthermore, by being able to prevent such intrusion and adhesion of muddy water, etc., it is possible to reliably prevent the transmission and generation of abnormal noises such as impact sounds and frictional noises as described above when the sliding door 3 is closed again. .

In the above embodiment, the convex mail hook 1 is fixed to the vehicle body 6 side, and the concave female hook 2 is fixed to the sliding door 3 side, but the structure may be reversed. It is something.

Further, in the above embodiments, the sliding door 3 is used as an opening/closing body, but the present invention is not limited to this. The present invention can be applied to the closing fixing structure of any opening/closing body, such as a general side door, back door, luggage door, etc., as long as it is a suitable part.

[Effect of idea]

As mentioned above, this invention involves sealing a lubricant into the convex part of a mail hook made of impregnated sintered alloy, keeping the surface of the convex part in a constant lubricated state, and providing a sealing material around the outer periphery of the female hook. It is designed to provide a seal when mating with the mail hook, and when the mail hook and female hook are mated with the opening/closing body in the closed state, a lubricating action is performed to prevent the connection between the vehicle body and the opening/closing body. Even when relative motion occurs, it is possible to reliably prevent frictional noise between the mail hook and the female hook.

In addition, during such fitting, the sealing material provided on the outer periphery of the female hook comes into elastic contact with the outer periphery of the female hook, so that these two members can be reliably sealed.
