Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle component and a mounting structure thereof.

[0002]

2. Description of the Related Art When a vehicle component having a plastic mounting portion is mounted on a vehicle with bolts or the like, the mounting member of the vehicle and the plastic mounting portion initially come into close contact with each other. And it is securely fixed. However, when the vehicle vibration and the accompanying vibration of the vehicle component exert a force greater than the limit between the vehicle component and the vehicle, the mounting portion of the vehicle component and the member to be mounted of the vehicle are moved relative to each other. Move, they rub each other,
Wear of the surface of the mounting portion occurs.

[0003] When such wear progresses, the relative movement between the mounting portion of the vehicle component and the mounted member of the vehicle becomes more and more severe due to the vibration, and the shaft such as a bolt or the like is moved. May also collide with the mounting hole of the mounting portion, causing a crack in the vicinity of the mounting hole of the mounting portion, and finally, the vehicle component falls off from the mounted member of the vehicle.

Therefore, in a vehicle component having a plastic mounting portion, a mounting portion in which a cylindrical collar is press-fitted and fixed in the mounting hole is used. Even if such a mounting portion is mounted to a member to be mounted on a vehicle with a bolt or the like, the shaft portion of the bolt or the like does not directly contact the plastic mounting portion. It does not take. In such a mounting portion, the thickness of the mounting portion in the vicinity of the mounting hole is made slightly thicker than the height of the cylindrical collar in the axial direction, and the mounting portion of the vehicle component and the vehicle are mounted on the mounting portion with bolts or the like. When the part is fastened, the pressing force acts not only between the bolt etc. and the collar, but also between the bolt etc. and the plastic part of the mounting part, so that the mounting part is securely attached to the mounting part. To fix it.

However, when a bolt or the like is tightened with a normal torque, the amount of compression of the plastic portion of the mounting portion in the thickness direction is extremely small, and the thickness corresponding to the amount is larger than the height of the collar. In order to control the dimensions of the plastic part of the mounting part, high precision is required in the manufacturing process, and this has caused an increase in cost. When the plastic portion of the mounting portion is thinner than the allowable dimension, the collar is pressed by tightening a bolt or the like, but the plastic portion of the mounting portion is not pressed. Further, when the plastic part of the mounting part is thicker than a predetermined allowable dimension, the plastic part of the mounting part is pressed by tightening a bolt or the like,
The collar is not pressed, causing the abrasion of the plastic part as described above, resulting in an unreliable attachment.

[0006] The present invention has been made in view of the above problems, and an object of the present invention is to provide a method for manufacturing
In particular, it is an object of the present invention to provide a vehicle component having a mounting portion that does not require high molding precision and that can be mounted with high reliability, and a mounting structure thereof.

FIG. 2 is a front view of a washer tank 18 which is a vehicle component of the present embodiment, and FIG. 3 is a plan view of the washer tank 18. As shown in these figures, the washer tank 18 has a plurality of mounting portions 21, 22, 2.
3 are provided, and these mounting portions 21, 22, 23
Thereby, it is attached to the attached member provided on the body of the automobile 10. The washer tank 18 and the plurality of mounting portions 21, 22, 23 are mainly formed of plastic. Note that, in the washer tank 18, the cylindrical portion extending upward is the cleaning liquid injection unit 50. Further, the washer pump 18 is attached to the washer tank 18 at a position indicated by a broken line in FIGS. 2 and 3.

The plurality of mounting portions 21, 22, and 23 are firstly a mounting portion 21 which is a primary mounting portion to be mounted on a member to be mounted, and a mounting portion 22 which is a secondary mounting portion which is subsequently mounted on the mounted portion. , 23.

The mounting position of the mounting portion 21, which is the primary mounting portion, is based on the mounting position. Therefore, the mounting hole 38 into which the screwing member to be mounted on the mounting portion is inserted is slightly smaller than that required for inserting the screwing member. The diameter is set to be slightly larger than the diameter of the screw member, with a sufficient margin. In the present embodiment, since an M6 bolt is used as the screwing member, the inner diameter of the mounting hole 38 as the primary mounting portion is 6.5 mm.

Attachment parts 22 and 23 as secondary attachment parts include
In order to allow an error in assembling the body of the automobile 10 and a molding error and an assembling error of the washer tank 18, a mounting hole 39 having a larger margin between the screwing member to be inserted and the primary mounting portion is provided. Have been. The same M6 bolt 60 as the primary mounting part 21 is inserted into the secondary mounting parts 22 and 23 as a screw member, but the inner diameter of the mounting hole 39 of the secondary mounting part is 11 mm. The mounting portions 22 and 23, which are the secondary mounting portions, are provided with mounting holes 3
Since the diameter of 9 is larger than the mounting portion 21 which is the primary mounting portion,
Head 61 of bolt 60 or washer 64 to be interposed
7 (see FIG. 7), and the amount by which the shaft of the bolt 60 can move is large.
Wear and breakage are likely to occur due to friction or collision with the second and the third.

Further, since the washer tank 18 includes the heavy washer pump 54, the center of gravity is biased near the washer pump 54. In the vicinity of the position of the center of gravity of such a washer tank 18, ie, the washer pump 5
In the vicinity of 4, the mounting portion 23 is located. A larger load is applied to the mounting portion 23 located near the center of gravity of the washer tank 18 than the other mounting portions 21 and 22.

FIG. 4 is a front view showing details of the mounting portion 23, and FIG. 5 is a schematic cross-sectional view showing a part of a portion taken along line VV of FIG. As shown in these drawings, the mounting portion 23 is configured to include a cylindrical collar 42 press-fitted into a mounting hole 39 provided in the mounting portion main body 26, and the mounting portion main body 26.

The mounting portion main body 26 is formed of plastic, and is provided around the mounting hole 39, that is, the head of the bolt 60 (the washer 64 when the washer 64 is interposed).
4 and FIG. 5, a first area 30 and a second area 34 are provided.

The first area 30, as shown in FIG. 5, is located around the mounting hole 39 and is thicker than the axial height of the collar 42. In the case of the present embodiment, the thickness of the first region 30 is 5.2 mm, and the height of the collar is 4.8 mm. As shown in FIG. 4, the first region 30 is
9 are a plurality of linear shapes radially surrounding 9.

FIG. 6A is a sectional view taken along line VI-VI in FIG. As shown in this figure, the first region 30 of the present embodiment has a rectangular cross-sectional shape and protrudes from the second region 34.

The second region 34 is the same as the first region 30 around the mounting hole 39, that is, the region facing the head of the bolt 60 (the washer 64 when the washer 64 is interposed). And is thinner than the first region 30 as shown in FIG.

As shown in FIG. 7, when a bolt 60, which is a screw member for attaching the attaching portion 23 to the member 14 to be attached, is screwed to the member 14 to be attached, the bolt 60
The first region 30 is compressed by the pressing force exerted by the head 61 (via the washer 64 in the present embodiment). In the case of the present embodiment, the predetermined tightening torque for screwing the bolt 60 is 30 kgf.
· Cm, and when the pressing force corresponding to the tightening torque is applied, the first region 30 receives the pressing force, and the amount by which the first region 30 can be compressed in response to the pressing force is 0.1 mm.
6 mm. However, since the washer reaches the collar before reaching the compression amount, the compression amount of the first region 30 is obtained by subtracting the color height 4.8 mm from the thickness 5.2 mm of the first region 30. 0.4 mm.

As described above, the first pressing force corresponding to the predetermined torque for tightening the bolt 60 serving as the screwing member is used.
The amount by which the region 30 can be compressed is greater than the amount by which the thickness of the first region 30 exceeds the axial height of the collar 42.
This relationship is the first in the state where the pressing force is not applied.
The thickness of the region 30 is T, and the bolt 60 as a screw member is
ΔT is the amount by which the first region 30 can be compressed in accordance with the pressing force applied when is tightened with a predetermined torque.
If the height of the collar 42 is C, it is expressed by the following equation.

ΔT> (TC) (1) Therefore, the bolt 60 which is a screw member with a predetermined torque
Is tightened, the first region 30 is compressed, and the mounting portion side of the head of the bolt 60 (when the washer 64 is interposed, the mounting portion 23 side) always comes into close contact with the collar 42. As a result, the mounting portion side of the head 61 of the bolt 60 (when the washer 64 is interposed, the mounting portion side)
The attachment portion 23 is attached to the attached member 14 in a state where the attachment portion 23 is in close contact with the first region 30 and the collar 42. The axial height of the collar 42 and the thickness of the first region 30 are
The states are almost equal.

As described above, the region around the mounting hole 39 including at least the first region 30 in the mounting portion main body 26 is
The head 61 of the bolt 60 is in close contact with the mounting portion 23 side (when the washer 64 is interposed, the mounting portion 23 side). Moreover, the head 61 and the like of the bolt 60 cannot compress the periphery of the mounting hole 39 of the mounting portion main body 26 to the height of the collar 42 or less. Therefore, the area around the mounting hole 39 of the mounting portion main body 26 is worn or damaged by friction or collision with the head 61 of the bolt 60 or the like, and the adhesion of the bolt 60 to the head 61 or the like is deteriorated and the mounting is performed. There is no deterioration of reliability.

A thick first region 3 is provided around the mounting hole 39, that is, in a region facing the head of the bolt 60 (the washer 64 when the washer 64 is interposed).
Since the second region 34 having a thickness smaller than that of the first region 30 as well as the first region 30 is also arranged, compared with the case where the entire periphery of the mounting hole 39 has the same thickness as the first region 30. And
It becomes easy to compress and deform the area around the mounting hole 39 by the pressing force of the bolt 60 or the like. Therefore, without making the molding thickness accuracy in the manufacturing process higher than usual,
The head 61 of the bolt 60 and the like and the periphery of the collar 42 and the mounting hole 39 of the mounting portion main body 26 can be reliably contacted.

Specifically, in the case of the present embodiment, the area where the washer 64 faces the mounting portion main body 26 is approximately 121 mm ^2.
However, since the first area 30 is thicker than the collar 42 and the second area 34, the contact area between the washer 64 and the area around the mounting hole 39 is about 20 mm ² .
Therefore, even when the same pressing force is applied, the mounting holes 3
As compared with the case where the periphery of 9 is made uniform, the stress is about 6 times, and a large amount of compression is obtained in the first region 30. For example, in the present embodiment, the first region 30 is compressed by about 0.6 mm with a pressing force when the bolt 60 is screwed with a torque of 30 kgf · cm.

However, unlike the present embodiment, if the mounting portion main body has a uniform thickness around the mounting hole,
With the same pressing force, only 0.1 mm will be compressed. Moreover, in order to mount the mounting portion in a highly reliable state, it is necessary to satisfy the above-described expression (1). Therefore, the mounting portion main body is allowed only a molding error of a thickness of 0.1 mm around the mounting hole. Will be. In order to suppress the molding of the mounting portion main body within the range of the error, it is necessary to make the precision of the manufacturing process higher than that of the normal part.

On the other hand, in order to satisfy the expression (1), the mounting portion main body 26 of the mounting portion 23 of the present embodiment needs the first region 30.
May be manufactured within an error range of 0.6 mm. Therefore, in the case of the present embodiment, it is not necessary to make the accuracy of the manufacturing process higher than usual, and there is no accompanying cost increase.

The first region 30 of the present embodiment is not limited to the shape shown in FIG. 6A as a cross section taken along the line VI-VI in FIG. Or Figure 6
The cross section may be formed as shown in FIG.

The first region 30 corresponds to FIG. 5 and FIG.
As shown in FIG.
1 is an exploded cross-sectional view showing a state where the mounting portion 24 is mounted to the mounted member 14 using the bolt 60 and the washer 64 without being limited to the one protruding from the second area 34 on the side corresponding to 1. As shown in FIG.
In the side facing the attached member 14 in the above, the above-described equation (1)
The first region 30 may be formed so as to protrude from the second region 34 while satisfying the above conditions. Also in this case, as in the case described above, the protruding portion of the first region 30 is mainly compressed by the pressing force applied by the head portion 61 (the washer 64 when a washer is used) of the bolt 60 as the screw member. And the head 61 of the bolt 60 (or washer 64)
Can be easily brought into close contact with the collar 42 and the first region 30 without increasing the processing accuracy of the mounting portion, and a highly reliable mounting can be obtained. In this case, the area around the mounting hole 39 including the first area 30 and the second area 34 is formed so as to occupy the entire area in contact with the mounted member 14.

Further, the first area 30 is not a plurality of straight lines formed radially around the mounting hole 39 as shown in FIG. 4, but, for example, details of the mounting portion 23 are shown in FIG. (A) or as shown in FIG. 9 (B). FIG. 9A shows an example in which the first region 30 is formed on a concentric circle of the mounting hole 39 as a plurality of small circular regions surrounding the mounting hole 39. FIG. 9B shows an example in which the first region 30 is formed as one annular region surrounding the mounting hole 39.
