Description

[Technical Field]

[0001] The present invention relates to a mounting structure for a housing of an in-vehicle component. [Background technology]

[0002] Although clips are used to attach the housings of in-vehicle components to the vehicle body, as shown in Patent Documents 1 and 2, bolts are widely used as a more secure and firm attachment method. When bolts are used, the bolts and nuts must be screwed in, and therefore the attachment work cannot be carried out as easily as with clips.

[0003] Therefore, by inserting a positioning pin (locating pin) provided on the housing into a positioning hole provided on the vehicle body, the housing is positioned relative to the vehicle body and temporarily held in place in advance, and then bolted in place. By positioning the housing with the positioning pin and temporarily holding it in place in this way, it is possible to simplify the installation work. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE INVENTION

[0011] Before describing the embodiments of the present invention, the problems to be solved by the present invention will be described in detail. 14 and 15 show an example of a case where the housing of an in-vehicle component is fixed with bolts while being positioned with a positioning pin. 14 and 15, two mounting brackets 12 each having a bolt-through hole 13 are provided at the upper end of a housing 11 of an on-vehicle component 110. A positioning pin 20 protrudes downward from the lower end of the housing 11. Meanwhile, the vehicle body 1 to which the housing 11 is to be attached is provided with positioning holes 2 into which the positioning pins 20 are inserted and stud bolts 3 that pass through the bolt-through holes 13 and onto which nuts 5 are screwed from above the mounting brackets 12 to fasten the mounting brackets 12 to the vehicle body 1.

[0012] The bolt holes 13 provided in the two mounting brackets 12 are elongated holes extending in directions perpendicular to each other. The bolt hole 13 in the mounting bracket 12 on the left side in Fig. 14 is a first elongated bolt hole 13A extending in a direction (up and down in the illustrated example) parallel to the insertion direction of the positioning pin 20 (direction of arrow S). The bolt hole 13 in the mounting bracket 12 on the right side in Fig. 14 is a second elongated bolt hole 13B extending in a direction (left and right in the illustrated example) perpendicular to the insertion direction of the positioning pin 20.

[0013] Therefore, even if the positions of the two stud bolts 3 and the positions of the two bolt-through holes 13 are slightly misaligned within the range of dimensional tolerance, the stud bolts 3 can be passed through the bolt-through holes (long holes) 13.

[0014] However, in reality, the position of the housing 11 is determined by first passing the positioning pin 20 through the positioning hole 2 of the vehicle body 1. For this reason, depending on the direction of the misalignment between the stud bolt 3 and the positioning hole 2, if the misalignment is large even within the range of the dimensional tolerance, there is a possibility that the stud bolt 3 will not be able to enter the bolt-through hole 13.

[0015] For example, Figure 16 shows a cross section taken along the line AA in Figure 14. If there is little or no misalignment between the stud bolt 3 passed through the second elongated bolt-passing hole 13B and the positioning hole 2, the stud bolt 3 can be passed through the second elongated bolt-passing hole 13B without any problems, and the nut can be tightened.

[0016] However, as shown in Figure 17, if the misalignment between the stud bolt 3 passed through the second bolt-through slot 13B and the positioning hole 2 is large even if it is within the range of the dimensional tolerance, the stud bolt 3 may interfere with the housing 11, for example, within the range indicated by the circle K in Figure 17. In this case, the stud bolt 3 may not be able to be passed through the second bolt-through slot 13B, and it may not be possible to tighten the nut. In other words, depending on the size of the error in the dimension H between the positioning hole 2 and the stud bolt 3, it may not be possible to pass the stud bolt 3 through the second bolt-through slot 13B, and it may not be possible to fasten the housing 11 with the bolts.

[0017] As described above, if the housing 11 is positioned and temporarily held in place in advance with the positioning pin 20, the stud bolt 3 can be easily passed through the bolt-through hole 13 of the mounting bracket 12, making the installation process easier. However, depending on the degree of misalignment between the positioning hole 2 into which the positioning pin 20 is inserted and the stud bolt 3, problems may arise when fastening the bolt.

[0018] Specific embodiments of the present invention will be described below with reference to the accompanying drawings. Fig. 1 is a front view showing a mounting structure according to an embodiment of the present invention, and Fig. 2 is a cross-sectional view taken along line AA in Fig. 1. First, the contents common to the embodiments described below will be described.

[0019] 1 and 2, two mounting brackets 12 each having a bolt-through hole 13 are provided at the upper end of a housing 11 of an in-vehicle component 10. In addition, a positioning pin 20, which is an example of a positioning member, is provided at the lower end of the housing 11 so as to protrude downward. The bolt-through hole 13 is a portion corresponding to a fixing portion on the housing 11 side.

[0020] The on-vehicle part 10 described here is the main body of a protector for a wire harness, but may be other types of on-vehicle part. A cover, which will be described later, is attached to the main body of this protector as needed. The illustrated example is simplified for ease of understanding. In this embodiment, the vehicle body (vehicle) 1 to which the part is attached is a vehicle body panel.

[0021] At the mounting location of this component on the vehicle body (vehicle body panel) 1 to which the housing 11 is to be attached, a positioning hole 2 into which a positioning pin 20 is inserted is provided in the lower panel wall, and two stud bolts 3 that are passed through bolt-through holes 13 are provided on the side panel wall so as to protrude horizontally. The housing 11 is attached to the vehicle body 1 by passing the stud bolts 3 through the bolt-through holes 13, screwing nuts 5 onto the stud bolts 3 from above the mounting bracket 12, and then fastening the mounting bracket 12 with the bolts.

[0022] The bolt holes 13 provided in the two mounting brackets 12 are elongated holes extending in directions perpendicular to each other. The bolt hole 13 in the left mounting bracket 12 in Fig. 1 is a first elongated bolt hole 13A extending in a direction (up and down in the illustrated example) parallel to the insertion direction of the positioning pin 20 (the direction of arrow S). The bolt hole 13 in the right mounting bracket 12 in Fig. 1 is a second elongated bolt hole 13B extending in a direction (left and right in the illustrated example) perpendicular to the insertion direction of the positioning pin 20.

[0023] Positioning pin 20 protruding from the lower end of housing 11 is inserted into positioning hole 2 provided in vehicle body 1 to position and temporarily hold housing 11 relative to vehicle body 1 at a stage before bolt fixing. Also, bolt-through hole 13 provided in mounting bracket 12 of housing 11 is used to permanently fix housing 11 to vehicle body 1 in a state in which housing 11 has been positioned and temporarily held relative to vehicle body 1 by positioning pin 20.

[0024] As described above, the elongated holes (13A, 13B) extending in two mutually perpendicular directions allow the stud bolts 3 to be passed through the bolt-through holes (elongated holes) 13 even if the positions of the two stud bolts 3 and the positions of the two bolt-through holes 13 are slightly misaligned within the range of dimensional tolerance.

[0025] However, in reality, the position of the housing 11 is determined by first passing the positioning pin 20 through the positioning hole 2 of the vehicle body 1. For this reason, depending on the direction of misalignment between the stud bolt 3 and the positioning hole 2, if the misalignment is large even within the range of the dimensional tolerance, the stud bolt 3 may not be able to enter the bolt-through hole 13. For this reason, the mounting structure of this embodiment is provided with a leaf spring 21, which will be described below.

[0026] A leaf spring 21 is provided at the base of the positioning pin 20 as a spring structure. The leaf spring 21 is configured to be elastically deformable when the housing 11 is positioned by the positioning pin 20, thereby enabling displacement of the housing 11 relative to the vehicle body 1. The leaf spring 21 is interposed between the housing 11 and the positioning pin 20. In other words, the leaf spring 21 provided with the positioning pin 20 functions to enable displacement of the housing 11 in order to correct misalignment between the bolt-through hole (fixing portion) 13 and the stud bolt 3 on the vehicle body 1 side.

[0027] The leaf spring 21 is provided in a shape that corresponds to a rectangular notch 22 provided in a part of the bottom wall 11b of the housing 11 (see FIG. 5, etc.). That is, a rectangular notch 22 is provided in a part of the bottom wall 11b of the housing 11, and the rectangular leaf spring 21 is provided in a cantilevered manner, positioned outside the notch 22, so that it can elastically deform inward of the housing 11. The positioning pin 20 is provided on the underside of the leaf spring 21 so as to protrude downward. The leaf spring 21 and its surrounding structure will be described in detail later.

[0028] FIG. 3 is a cross-sectional view showing a case where the stud bolt 3 interferes with the housing 11, and FIG. 4 is a cross-sectional view showing a state where, in order to avoid the interference in FIG. 3, the housing 11 is pushed down while elastically deforming the spring structure (leaf spring 21), thereby correcting the misalignment between the stud bolt 3 and the bolt-through hole 13 (13B).

[0029] 1 and 2, when attaching the housing 11 to the vehicle body 1, first, the positioning pin 20 at the bottom end of the housing 11 is inserted into the positioning hole 2 on the vehicle body 1 side. This positions the housing 11 of the on-vehicle component 10 at the component mounting location on the vehicle body 1 and temporarily holds it in place. Next, the stud bolt 3 on the vehicle body 1 side is passed through the bolt-through hole 13 of the mounting bracket 12, and a nut 5 is screwed onto the stud bolt 3 from above the mounting bracket 12, thereby bolting the housing 11 to the vehicle body 1.

[0030] However, as shown in Figure 3, if there is misalignment between the bolt-through hole 13 of the mounting bracket 12 when the stud bolt 3 is passed through the bolt-through hole 13, the stud bolt 3 may interfere with the housing 11, as shown by the circle K in Figure 3. In other words, a situation may arise in which the stud bolt 3 cannot be passed through the bolt-through hole 13.

[0031] In such a case, as shown in Figure 4, the housing 11 is pushed down in the direction of arrow S (the insertion direction of the positioning pin 20) while elastically deforming the leaf spring 21. By pushing down the housing 11 in the direction of arrow S, the bolt-through hole 13 of the mounting bracket 12 is aligned with the stud bolt 3, allowing the stud bolt 3 to be securely inserted through the bolt-through hole 13. Therefore, the housing 11 can be securely bolted down with the nut 5.

[0032] As described above, by displacing the housing 11 downward while elastically deforming the spring structure (leaf spring 21), it is possible to absorb any misalignment between the fixing part (bolt-through hole 13) and the vehicle body (stud bolt 3) and to properly correct the positional relationship between the fixing part and the vehicle body. This makes it possible to reliably fix the housing of the on-vehicle component to the vehicle body.

[0033] FIG. 5 is a perspective view showing the configuration of the spring structure (leaf spring 21) according to the first embodiment of the present invention. A rectangular notch 22 is provided in a portion of the bottom wall 11b of the housing 11. The bottom wall 11b is a plate that is bent from the main plate portion 11a of the housing 11. A rectangular leaf spring 21 that is slightly smaller than the notch 22 is provided to correspond to the rectangular notch 22. The leaf spring 21 is composed of a connecting portion 21a that is integrated with the bottom wall 11b and the main plate portion 11a, and a leaf spring main portion 21b that is continuous with the connecting portion 21a via a bending hinge portion 21c. The leaf spring main portion 21b is located outside the housing of the notch 22 and in a position parallel to the bottom wall 11b. A positioning pin 20 protrudes from the outer surface (the bottom surface in FIG. 1) of the leaf spring main portion 21b.

[0034] Figure 6 is a cross-sectional view showing the state in which the underside of the leaf spring 21 (leaf spring main body 21b) that constitutes the spring structure of Figure 5 comes into contact with the vehicle body 1 as the positioning pin 20 is inserted into the positioning hole 2 on the vehicle body 1 side.

[0035] As shown in Figure 6, when the positioning pin 20 is inserted into the positioning hole 2 on the vehicle body 1 side, the underside of the leaf spring 21 (leaf spring main body portion 21b) comes into contact with the vehicle body 1. Therefore, when a downward force is applied to the housing 11, the leaf spring 21 receives a reaction force from the vehicle body 1 and elastically deforms inward in the housing 11, making it possible to press down the housing 11. This makes it possible to correct any misalignment between the stud bolt 3 on the vehicle body 1 side and the bolt-through hole 13 on the housing 11 side.

[0036] FIG. 7 is a perspective view showing the housing 11 in the first embodiment and the cover 31 that covers the housing 11, FIG. 8 is a perspective view showing the state in which the cover of FIG. 7 is placed over the opening surface of the housing, thereby protecting the leaf spring that constitutes the spring structure with the protective part of the cover, and FIG. 9 is an enlarged view of the main part of FIG. 8.

[0037] As shown in FIG. 7, the housing 11 is box-shaped and has a main plate portion 11a, a lower end wall 11b, and an upper end wall 11c, and a cover 31 is fitted over the open surface. As shown in FIG. 8, edge walls 32 are provided on both side edges of the cover 31, which cover the upper and lower end walls 11c, 11b of the housing 11. One of the edge walls 32 is provided with a protective portion 33. When the cover 31 is fitted over and secured to the housing 11, the protective portion 33 covers the free end of the leaf spring 21 of the housing 11, as shown in FIG. 9, thereby preventing excessive outward deformation of the leaf spring 21 and protecting the leaf spring 21. The presence of this protective portion 33 prevents damage to the flexural hinge portion 21c of the leaf spring 21.

[0038] FIG. 10 is a perspective view showing the configuration of a spring structure (leaf spring 21) according to the second embodiment of the present invention. 10, in the in-vehicle component 10B of this embodiment, a restricting portion (restricting wall) 11e is provided inside the cantilevered leaf spring 21 to restrict the range of movement of the leaf spring 21 toward the inside of the housing. This restricting portion 11e is provided so as to be continuous with the lower end wall 11b and the main plate portion 11a at a position opposite the leaf spring 21 from a notch 22 formed in the lower end wall 11b of the housing 11. The provision of the restricting portion 11e makes it possible to suppress excessive elastic deformation of the leaf spring 21. Furthermore, the rigidity of the housing 11 can be improved by providing the restricting portion 11e continuous with the lower end wall 11b and the main plate portion 11a.

[0039] In the second embodiment, as in the first embodiment, the leaf spring 21 elastically deforms inwardly in the housing 11, making it possible to press down the housing 11, and as a result, it is possible to correct any misalignment between the stud bolt 3 on the vehicle body 1 side and the bolt-through hole 13 on the housing 11 side. Therefore, the stud bolt 3 and the housing 11 do not interfere with each other, and the part can be assembled to the vehicle body.

[0040] Similarly to the first embodiment, the flat spring 21 can be protected by covering the housing 11 of the in-vehicle component 10B of the second embodiment with the cover 31.

[0041] FIG. 11 is a perspective view showing the configuration of a spring structure according to the third embodiment of the present invention. As shown in FIG. 11 , in the in-vehicle component 10C of this embodiment, the leaf spring 21B is positioned in the notch 22 on the same plane as the bottom wall 11b. A disk-shaped abutment plate portion 25 is provided midway along the length of a positioning pin 20 protruding from the bottom surface (outer surface) of the leaf spring 21B. This abutment plate portion 25 is a portion that receives a reaction force from the vehicle body 1 by abutting against the vehicle body 1 when the positioning pin 20 is inserted into the positioning hole 2 on the vehicle body side. The reaction force is transmitted to the leaf spring 21B via the positioning pin 20. Protective portions 11f, 11f are provided on both sides of the leaf spring 21B in the width direction. The protective portions 11f, 11f are provided contiguous to the bottom wall 11b of the housing 11, thereby preventing excessive outward deformation of the leaf spring 21B.

[0042] In the third embodiment, as in the first embodiment, the leaf spring 21B elastically deforms inward in the housing 11, making it possible to press down the housing 11, and as a result, it is possible to correct any misalignment between the stud bolt 3 on the vehicle body 1 side and the bolt-through hole 13 on the housing 11 side. Therefore, the stud bolt 3 and the housing 11 do not interfere with each other, and the part can be assembled to the vehicle body.

[0043] Similarly to the first embodiment, the housing 11 of the in-vehicle component 10C of the third embodiment can be covered with the cover 31 to protect the leaf spring 21B.

[0044] FIG. 12 is an oblique view showing the configuration of a spring structure part of a fourth embodiment of the present invention, and FIG. 13 is a cross-sectional view showing the state in which the abutment plate part of the positioning pin protruding from the leaf spring that constitutes the spring structure part of FIG. 12 comes into contact with the vehicle body as the positioning pin is inserted into the positioning hole on the vehicle body side.

[0045] 12 and 13, in the in-vehicle component 10D of this embodiment, a restricting portion (restricting wall) 11e is provided inside the cantilevered leaf spring 21B of the third embodiment, restricting the range of movement of the leaf spring 21B toward the inside of the housing. This restricting portion 11e is provided on the opposite side of the leaf spring 21 from the notch 22 formed in the bottom wall 11b of the housing 11, and is provided so as to be continuous with the bottom wall 11b and the main plate portion 11a. By providing this restricting portion 11e, excessive elastic deformation of the leaf spring 21 can be suppressed. Furthermore, by providing the restricting portion 11e so as to be continuous with the bottom wall 11b and the main plate portion 11a, the rigidity of the housing 11 can be improved.

[0046] In the fourth embodiment, as in the first embodiment, the flat spring 21B elastically deforms inwardly of the housing 11, making it possible to press down the housing 11, and as a result, it is possible to correct any misalignment between the stud bolt 3 on the vehicle body 1 side and the bolt-through hole 13 on the housing 11 side. Therefore, the stud bolt 3 and the housing 11 do not interfere with each other, and the part can be assembled to the vehicle body.

[0047] Similarly to the first embodiment, the housing 11 of the in-vehicle component 10D of the fourth embodiment can be covered with the cover 31 to protect the leaf spring 21B.

[0048] The present invention is not limited to the above-described embodiments, and can be appropriately modified, improved, etc. In addition, the material, shape, dimensions, numerical values, form, number, location, etc. of each component in the above-described embodiments are arbitrary and not limited as long as they can achieve the present invention.

[0049] For example, the position where the bending hinge portion 21c of the leaf springs 21, 21B is provided is not limited to the position of the bottom side of the notch 22 as in the illustrated example, but may be on the left or right side of the notch. Also, instead of the leaf springs 21, 21B, rubber, a spiral spring, or the like may be used as the spring structure. Also, the leaf spring 21 and the positioning pin 20 may be configured as an integral unit, or may be configured as separate units and positioned at a distance.
