  However, when such a conventional radiator support for a vehicle is assembled to a vehicle or transported for assembling a cooling part to the radiator support, if it is left as a finished product, there is an individual space due to the presence of the internal space of the support unit. While the occupied volume becomes large and the transportation efficiency is poor, when the transportation is performed in a state before assembling divided into a plurality of parts, the assembling workability at the transportation destination is not good.

  The present invention has been made against the background described above, and its object is to improve transportation efficiency while ensuring assembly workability at a transportation destination.

  In order to achieve such an object, the first invention provides a radiator support for a vehicle having a rectangular frame-shaped support portion that is integrally fixed to a vehicle body and supports a cooling component in a substantially rectangular space. The support portion is composed of a plurality of frame components connected so as to be relatively rotatable around a predetermined rotation center, and can be transported in a folded state by being rotated around the rotation center.

  According to a second aspect of the present invention, in the vehicle radiator support according to the first aspect of the present invention, a pair of frame configurations are connected so as to be capable of relative rotation about the rotation center by being rotated and folded around the rotation center. One of the parts is housed inside the other.

  A third aspect of the present invention is the vehicle radiator support of the first or second aspect of the present invention, wherein each of the plurality of frame constituent parts is divided into two at an intermediate position between two parallel sides of the rectangular frame shape. The pair of frame components are connected so as to be relatively rotatable around the rotation center at the divided position.

  According to a fourth aspect of the present invention, there is provided the vehicle radiator support according to the third aspect, wherein one of the pair of U-shaped frame components is connected to the inside of the other frame component. The dimension in the direction parallel to the axis is shortened, and one of the frame components is accommodated inside the other frame component by being rotated and folded around the center of rotation. .

A fifth aspect of the present invention is the vehicle radiator support according to any one of the first to fourth aspects of the present invention, wherein (a) the support portion is (a-1) disposed substantially horizontally in the left-right direction of the vehicle, and the cooling component. A radiator support upper that supports the upper part of the radiator, and (a-2) a radiator support lower that is disposed below the radiator support upper and parallel to the radiator support upper and supports the lower part of the cooling component, and (a- 3) A pair of radiator support sides that are spaced apart in the left-right direction of the vehicle and are disposed in the vertical direction across the radiator support upper and the radiator support lower, and connect the radiator support upper and the radiator support lower. On the other hand, (b) it is divided into two substantially horizontally at the intermediate position in the vertical direction of the pair of radiator support sides, so that each of the U-shapes in the front view as seen from the front of the vehicle. A pair of upper frame component and lower frame component are provided as the plurality of frame components, and are connected so as to be relatively rotatable around a substantially horizontal rotation center at the divided position. To do.
The fifth aspect of the invention prescribes the division position and the like assuming the mounting state in the vehicle, and does not mean that the vehicle is actually mounted in the vehicle.

  In such a vehicle radiator support, the support portion is composed of a plurality of frame components connected so as to be relatively rotatable around a predetermined rotation center, and is rotated around the rotation center. Since it can be transported in a folded state, the space inside the support part is opened, and the degree of freedom of loading during transportation is increased, and any one of the plurality of frame constituent parts is replaced with another frame constituent part. If it can be stored inside, the occupying volume is reduced and the transportation efficiency is improved. In addition, since the plurality of frame components are merely rotated around a predetermined rotation center and folded, the rotation is performed around the rotation center to obtain a predetermined assembly state, and positioning is simply performed using a bolt or the like. Since it can be in an assembled state (finished product), it is easier to assemble than a case where a plurality of completely separated frame components are aligned and assembled together.

  In the second aspect of the invention, since one of the pair of frame components connected so as to be relatively rotatable around the rotation center is housed inside the other, the occupied volume during transportation is reduced and transportation efficiency is improved. To do.

  In the third aspect of the invention, a pair of U-shaped frame components divided into two at an intermediate position between two parallel sides of a rectangular frame shape are connected so as to be relatively rotatable around the rotation center at the divided position. Therefore, the structure is simple and inexpensive compared to the case of dividing into three or more frame components or dividing into a rectangular frame shape diagonal direction.

  In the fourth invention, the dimension in the direction parallel to the rotation center is shortened so that one of the pair of U-shaped frame components is positioned and connected to the inside of the other frame component, Since it is rotated around the center of rotation and folded, it is housed inside the other frame constituent part, so that the occupied volume during transportation is reduced as in the second invention, and transportation efficiency is improved.

  The fifth aspect of the present invention is a radiator support upper that supports the upper part of the cooling component, a radiator support lower that supports the lower part of the cooling component, and the radiator support upper and the radiator support lower that are disposed vertically. In the case where the support portion is configured with a pair of radiator support sides, the upper frame component and the lower frame component are divided into two substantially horizontally at an intermediate position in the vertical direction of the pair of radiator support sides. Since they are divided, the radiator support upper and the radiator support lower that support the cooling component may basically be the same as before, and the supporting performance of the cooling component is maintained well.

  The vehicle radiator support according to the present invention is provided with positioning means for positioning the plurality of relatively rotatable frame components in an assembled state as necessary so as to function as a radiator support. That is, by rotating a plurality of frame components around the rotation center and fixing them to the frame of the vehicle body, etc., they may be held in a predetermined assembly state that functions as a radiator support. In order to facilitate the assembling work with respect to the vehicle body, it is desirable that the vehicle radiator support can be positioned by positioning means such as bolts or welding so as to be held in an assembled state (finished product).

  In the second invention, one of the pair of frame components is accommodated inside the other by being rotated by being rotated approximately 180 ° around the rotation center, but the first invention is implemented. In this case, the pair of frame components may be folded in a hairpin shape so as to be arranged substantially in parallel, or may be folded in a state of being opened at a predetermined angle in an acute angle shape (pine needle shape).

  In the third aspect of the invention, a pair of U-shaped frame components divided into two at an intermediate position between two parallel sides of a rectangular frame shape are connected so as to be relatively rotatable around the rotation center at the divided position.

In addition, “up”, “front”, and “left” of the arrows shown in the figure mean the upper side of the vehicle, the front side of the vehicle, and the left side of the vehicle when the vehicle radiator support 10 is mounted on the vehicle. It does not mean that it is actually mounted on the vehicle. The same applies to the other drawings.

  The support portion 30 is spaced apart in the left and right direction of the vehicle by the radiator support upper 12 that is disposed substantially horizontally in the left and right direction of the vehicle, the radiator support lower 14 that is disposed substantially in parallel below the radiator support upper 12. The radiator support upper 12 and the radiator support lower 14 are disposed in a vertical direction (substantially vertical direction) and a pair of radiator support sides 16 and 18 are connected to connect the radiator support upper 12 and the radiator support lower 14. The radiator support upper 12, the radiator support lower 14, and the pair of radiator support sides 16 and 18 form a substantially rectangular frame, and the substantially rectangular frame surrounded by the frame (the figure is a horizontally long rectangle). The radiator body 20 is integrally attached and supported in the space. The radiator main body 20 corresponds to a cooling component.

  The radiator support upper 12 is a press-molded product having a substantially U-shaped longitudinal section, and is disposed substantially horizontally in the left-right direction of the vehicle with the U-shaped opening side facing downward. A pair of holding holes 22 are provided apart from each other in the left-right direction as an upper mounting portion for fixing the upper end of the radiator main body 20 together with a vehicle frame (not shown). The holding hole 22 is a burring hole provided by pressing at the same time when the radiator support upper 12 is press-molded in a flat portion that is substantially horizontal when installed in the vehicle, that is, a U-shaped back surface portion, and upwards. A protruding cylindrical flange is integrally provided, and the upper portion of the radiator body 20 is integrally attached via an elastic body such as rubber.

  The radiator support sides 16 and 18 are each composed of two members, an upper support side 16a and 18a and a lower support side 16b and 18b, and the upper support side 16a and 18a and the lower support side 16b, 18b is integrally connected by a pair of connecting bolts 36 and 38, respectively. The upper support sides 16a and 18a and the lower support sides 16b and 18b are press-formed products each having a substantially U-shaped cross section, and the upper support sides 16a and 18a are U-shaped. Arranged substantially vertically in the vertical direction of the vehicle with the opening side facing inward, and fixed to the left and right ends of the radiator support upper 12 at the upper end thereof by means of fixing means such as welding or bolts. Has been. The lower support sides 16b and 18b are disposed substantially vertically in the vertical direction of the vehicle with the U-shaped opening side facing outward, and are welded to the left and right ends of the radiator support lower 14 at the lower end thereof. The upper end is overlapped with the upper support side 16a, 18a back to back within a predetermined overlapping range, and is connected by the pair of connecting bolts 36, 38. It has become so. The mounting brackets 34 and 35 are integrally fixed to the lower support sides 16b and 18b by welding or the like.

  The radiator support lower 14 is a press-molded product having a substantially U-shaped cross-section in the same manner as the radiator support upper 12, and has a U-shaped opening side facing downward. A pair of holding holes that are disposed substantially horizontally in the left-right direction and are supported by the pair of radiator support sides 16 and 18 at both ends thereof, and as lower mounting portions for fixing the lower end of the radiator body 20 28 is spaced apart from the left and right. Similar to the holding hole 22 of the upper mounting portion, the holding hole 28 is formed in a flat portion that is substantially horizontal in the state of being mounted on the vehicle, that is, a U-shaped rear portion at the same time as the radiator support lower 14 is press-formed. A cylindrical flange protruding downward is integrally provided by a burring hole provided by pressing, and the lower portion of the radiator body 20 is integrally attached via an elastic body such as rubber.

  Here, the pair of radiator support sides 16, 18 is divided into two substantially horizontally at the middle position in the vertical direction, and is divided into the upper support side 16a, 18a and the lower support side 16b, 18b, In a state before being connected by the pair of connecting bolts 36 and 38, the support portion 30 having a rectangular frame shape has a pair of upper frame components 31 and a lower side each having a U-shape when viewed from the front of the vehicle. It is divided into two constituent parts, a frame constituent part 32. That is, the upper frame constituting part 31 is constituted by the radiator support upper 12 and a pair of upper support sides 16a and 18a integrally fixed to both ends thereof, and the lower frame constituting part 32 is constituted by the radiator support lower 14 and The lower support sides 16b and 18b are integrally fixed to both end portions, and both are configured symmetrically with respect to the horizontal center line. Then, the upper frame constituting portion 31 and the lower frame constituting portion 32 are connected by the upper connecting bolt 36 located on the upper side of the pair of connecting bolts 36 and 38 in the vicinity of the division position, thereby Relative rotation is possible around the rotation center S, which is the common axis of the upper connection bolt 36, and the upper frame component 31 is rotated about 180 ° as indicated by the arrow A shown in FIG. Thus, as shown by a solid line in FIG. 1C, the lower frame constituting portion 32 is substantially overlapped with the lower frame constituting portion 32 in a side view, that is, inside the pair of lower support sides 16b and 18b of the lower frame constituting portion 32. The upper frame component 31 can be folded so as to be accommodated. The upper connecting bolt 36 functions as a connecting member that connects the upper frame constituting portion 31 and the lower frame constituting portion 32 so as to be rotatable around the rotation center S. FIG. 3 is a perspective view showing a state in which the upper frame component 31 is folded so as to be housed inside the lower frame component 32 as shown in FIG.

  The width dimension in the left-right direction of the upper frame component 31 is slightly smaller than the width dimension in the left-right direction of the lower frame component 32, and is accommodated inside the lower frame component 32. The outer dimension L1 from the rotation center S to the upper frame outer end of the upper frame component 31 is larger than the inner dimension L2 from the rotation center S to the lower frame inner end of the lower frame component 32, that is, the upper surface of the radiator support lower 14. Is also small. Further, as is apparent from FIG. 2 (a), which is an enlarged view of the IIA-IIA cross section in FIG. 1 (a), the upper connecting bolt 36 is provided in the width direction of each of the upper support side 16a and the lower support side 16b ( The two are connected at the center position in the vertical direction in FIG. Therefore, if the width dimensions of the upper support side 16a and the lower support side 16b are substantially the same or the lower support side 16b is made larger (the embodiment is the same), the upper frame constituting portion 31 becomes the lower frame constituting portion 32. It is stored so as to overlap inside. FIG. 1B shows an assembled state (finished product) in which the lower connection bolt 38 is mounted, and is in a state before the connection bolt 38 is mounted and before the connection bolt 36 is completely tightened. 1 (c) and FIG. 3 can be folded. The upper frame constituting portion 31 indicated by the alternate long and short dash line in FIG.

  As is clear from FIG. 2 (a), a washer 40 is disposed between the upper support side 16a of the upper frame constituting portion 31 and the lower support side 16b of the lower frame constituting portion 32. The upper frame component 31 and the lower frame component 32 can be smoothly rotated. The upper connecting bolt 36 is a centering bolt having a tapered portion 36b and a cylindrical portion 36c concentrically and integrally formed at the base of the screw portion 36a as shown in FIG. 2 (b). The support side 16a and the lower support side 16b can be connected to each other so as to be relatively rotatable in a state of being aligned with high accuracy, and the upper frame constituting portion 31 is moved upward as shown in FIGS. 1 (a) and 1 (b). By being firmly tightened with respect to the nut 42 in the vertically assembled state, both can be integrally fixed with high positional accuracy. The lower connecting bolt 38 is also constituted by a centering bolt, and the upper support side 16a and the lower support side 16b are integrally fastened with a washer similar to the washer 40 sandwiched therebetween, In cooperation with the connecting bolt 36, the upper frame component 31 and the lower frame component 32 are positioned with high accuracy in an assembled state in which the upper frame component 31 and the lower frame component 32 are aligned in a side view and are fixed together. The lower connecting bolt 38 functions as a positioning means for positioning the vehicle radiator support 10 that can rotate relative to the rotation center S in an assembled state. The insertion hole 44a provided in the upper support side 16a and the insertion hole 44b provided in the lower support side 16b are concentrically overlapped so as to coincide with each other when assembled, and the lower connection bolt 38 is inserted therethrough. It is. The radiator support side 18 side is configured symmetrically with the radiator support side 16 side.

  In the vehicle radiator support 10 of this embodiment, the support portion 30 is connected by a pair of upper connecting bolts 36 on both the left and right sides so as to be relatively rotatable about a rotation center S that is a common axis. The upper frame constituting portion 31 and the lower frame constituting portion 32 are rotated around the rotation center S and can be transported in a folded state, so that the transportation efficiency can be improved. That is, in the present embodiment, as shown in FIG. 3, the upper frame component 31 is stored so as to overlap the inner side of the lower frame component 32, so that the occupied volume is reduced to almost half. Thus, for example, as shown in FIG. 4 (a), as compared with the case where it is stored in the storage box 46 in an assembled state (finished product), it can be stored in a folded state as shown in FIG. 4 (b). Since the width dimension (dimension in the horizontal direction in FIG. 4) and depth (dimension in the direction perpendicular to the paper surface in FIG. 4) remain the same, the height dimension is reduced to almost half, so the storage box 48 becomes smaller. This improves transportation efficiency.

  Moreover, since it is folded so as to form a U-shape opened upward as shown in FIG. 3, the degree of freedom of loading during transportation is increased, and for example, part of other radiator support 10 for vehicles and others Can be loaded so as to enter the inside of the U-shape, and in this respect also, the transportation efficiency can be improved.

  On the other hand, since the upper frame constituting portion 31 and the lower frame constituting portion 32 are merely rotated around the predetermined rotation center S and folded, they are rotated relative to each other around the rotation center S and are shown in FIG. The assembled state shown in (a) and (b) is aligned by the lower connecting bolt 38, and the lower connecting bolt 38 and the upper connecting bolt 36 are firmly tightened, so that the assembled state (finished product) can be easily obtained. As compared with the case where a plurality of completely separated frame components are aligned and assembled together, the assembling work is easier. In the present embodiment, centering bolts are used as the upper connecting bolt 36 and the lower connecting bolt 38, so that the upper frame constituting portion 31 and the lower frame constituting portion 32 are aligned in an assembled state with high positional accuracy. Can be assembled together.

  Further, in the present embodiment, the upper side which is a pair of U-shaped frame components by being divided into two at an intermediate position between a pair of radiator support sides 16 and 18 which are two parallel sides of a rectangular frame shape. The frame component 31 and the lower frame component 32 are configured, and the upper frame component 31 and the lower frame component 32 are connected so as to be relatively rotatable around the rotation center S in the vicinity of the division position. Therefore, the structure is simple and inexpensive compared to the case where the frame is divided into three or more frame components or the diagonal direction of the rectangular frame.

  Further, in this embodiment, the radiator support upper 12 that supports the upper portion of the radiator body 20, the radiator support lower 14 that supports the lower portion of the radiator body 20, and the radiator support upper 12 and the radiator support lower 14 are straddled. In this case, the support portion 30 is configured to have a pair of radiator support sides 16 and 18 arranged in the vertical direction, and is substantially horizontally at the intermediate position in the vertical direction of the pair of radiator support sides 16 and 18. Since the upper frame constituting part 31 and the lower frame constituting part 32 are divided into two parts, the radiator support upper 12 and the radiator support lower 14 that support the radiator main body 20 may be basically the same as the conventional one. 20 support performance, for example, the positional relationship between the pair of holding holes 22, 28 Etc. can be well maintained.

  Next, another embodiment of the present invention will be described. In the following embodiments, parts that are substantially the same as those in the above embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.

  5 is provided with a pair of L-shaped contact brackets 52 and 54 as compared to the support portion 30 of the above embodiment, and the lower connection bolt 38 of the pair of connection bolts 36 and 38. Are different from each other in that they are connected so that they can rotate relative to each other with the rotation center S as the rotation center S, and can be folded. That is, in this embodiment, the lower connecting bolt 38 functions as a connecting member that connects the upper frame constituting portion 31 and the lower frame constituting portion 32 so as to be relatively rotatable about the rotation center S. One abutment bracket 52 is integrally fixed to the upper support side 16a by fixing means such as welding or bolts, and the other abutment bracket 54 is fixed to the lower support side 16b such as welds or bolts. As shown in FIGS. 5 (a) and 5 (b), they are integrally fixed by fixing means, and are brought into contact with each other as shown in FIGS. 5 (a) and 5 (b), so that the support sides 16a and 16b are in a substantially straight line. The rotation position is defined. FIG. 5 is a view showing the vicinity of the radiator support side 16 on the left side of the vehicle, where (a) is a side view of the assembled state seen from the left side of the vehicle, (b) is a front view of the assembled state seen from the front side of the vehicle, ) Is a side view of the folded state as seen from the left side of the vehicle. In FIG. 5 (c), the insertion hole 56a provided in the upper support side 16a and the insertion hole 56b provided in the lower support side 16b are overlapped concentrically so as to coincide with each other during assembly. Is inserted. The radiator support side 18 side is configured symmetrically with the radiator support side 16 side.

  In such a support portion 50, the upper frame constituting portion 31 is rotated in the direction opposite to the arrow A from the folded state shown in FIG. 5 (c), and the assembled state shown in FIGS. 5 (a) and 5 (b) is obtained. Since the assembled state (relative rotation position) is defined by bringing the pair of contact brackets 52 and 54 into contact with each other, the upper connection bolt 36 is inserted through the insertion holes 56a and 56b. As a result, the assembling work becomes easier and the rigidity of the connecting portion is improved. The pair of abutting brackets 52 and 54 function as positioning means for positioning in an assembled state together with the upper connecting bolt 36. If the contact brackets 52 and 54 are integrally fixed by spot welding, arc welding, or the like, the rigidity and strength of the connecting portion are further increased.

  The embodiment of FIG. 6 is a lower end portion of the upper support side 16a in the first embodiment, that is, a connection portion with the lower support side 16b, and a portion of the washer 40 facing the lower support side 16b. In the case where the concave seat surface 60 having a projection dimension substantially the same as the wall thickness is provided, the lower connection bolt 38 and the upper connection bolt 36 are simply tightened in the assembled state as shown in FIGS. 1 (a) and 1 (b) after transportation. In addition, the strength of the connecting portion that is positioned in the assembled state is improved by fixing the bottom of the concave seat surface 60 and the lower support side 16b in a state of surface contact with each other by spot welding or the like. Instead of the concave seating surface 60, a spacer having the same thickness as that of the washer 40 is prepared separately, and is interposed between the upper support side 16a and the lower support side 16b and fixed integrally by spot welding or the like. You may do it. Although the spacer can be fixed to either one of the support sides 16a or 16b by welding or the like in advance, after the lower connection bolt 38 and the upper connection bolt 36 are tightened after transportation, the support side 16a and 16b It may be inserted and welded between them, and in that case, there is a possibility that the operation when the upper frame constituting portion 31 and the lower frame constituting portion 32 are rotated relative to each other is lost due to the spacer being caught at the time of folding. Absent. In FIG. 6, an insertion hole 56 a provided on the insertion hole 44 a through which the lower connection bolt 38 is inserted is an insertion hole through which the upper connection bolt 36 is inserted.

  FIG. 7 shows a case in which the support portion 70 has a substantially square frame shape, and includes a pair of L-shaped frame configuration portions 72 and 74 divided into two along a diagonal line, and the connection bolt 36 and the like. The connecting member is connected so as to be capable of relative rotation about the rotation center S, which is the axis of the connecting member, and is positioned in the assembled state shown in FIG. It has come to be. One frame component 74 is shorter than the frame component 72 in the direction parallel to the rotation center S so as to be positioned and connected to the inside of the other frame component 72, and FIG. As shown in FIG. 7, the frame constituting portion 74 is accommodated inside the frame constituting portion 72 by being turned around the turning center S and folded. Also in this case, when the support portion 70 is folded in an L shape as shown in FIG. 7B, the dimension in the direction perpendicular to the rotation center S (the oblique upper left direction in FIG. 7B) is nearly half. Therefore, the same effects as in the above embodiment can be obtained, for example, the occupied volume is reduced and the transportation efficiency is improved.

  FIG. 8 shows a case where the support portion 80 has a rectangular frame shape, and is divided into three frame constituent portions 82, 84, and 86 by two parallel dividing surfaces in the vertical direction, and the divided portions are parallel to each other. This is a case where two substantially vertical rotation centers S1 and S2 are connected so as to be relatively rotatable. In this case, as shown in FIG. 8 (a), the U-shaped frame components 82 and 86 on both the left and right sides are rotated inward as indicated by arrows A and B, respectively. As shown in (b), the frame constituent portions 82 and 86 can be folded so as to overlap the inside of the frame constituent portion 84. Therefore, the same effect as that of the above-described embodiment can be obtained, for example, the size of the support portion 80 in the left-right direction is nearly half, the occupied volume is reduced, and the transport efficiency is improved.

  9 includes a pair of hinge members 94 in which a lower end portion of the upper support side 16a and an upper end portion of the lower support side 16b are connected to each other via a substantially horizontal hinge pin 92 so as to be relatively rotatable. This is a case of being connected by 96 so as to be relatively rotatable. These hinge members 94 and 96 are integrally fixed to the front surfaces of the upper support side 16a and the lower support side 16b by fixing means such as welding, respectively. The part 32 is connected so as to be relatively rotatable about a rotation center S that is the axis of the hinge pin 92, and the upper frame constituting part 31 is substantially parallel to the lower frame constituting part 32 as shown in FIG. Can be folded to FIG. 9 is a view showing the vicinity of the radiator support side 16 on the left side of the vehicle, (a) is a side view of the assembled state seen from the left side of the vehicle, (b) is a front view of the assembled state seen from the front side of the vehicle, ) Is a side view of the folded state as seen from the left side of the vehicle. The radiator support side 18 side is configured symmetrically with the radiator support side 16 side.

  In this case as well, the height dimension is nearly half and the U-shape opening upward in the front view seen from the front of the vehicle increases the degree of freedom of loading during transportation. Efficiency can be improved. In the assembled state shown in FIGS. 9A and 9B, the lower end of the upper support side 16a and the upper end of the lower support side 16b are brought into contact with each other, so that the relative rotational position in the assembled state is changed. Therefore, it is possible to easily perform the assembling work when positioning to the assembled state by positioning means (not shown) such as a bolt.

  As mentioned above, although the Example of this invention was described in detail based on drawing, these are one embodiment to the last, and this invention is implemented in the aspect which added the various change and improvement based on the knowledge of those skilled in the art. be able to.
