  However, the invention described in Patent Document 1 described above is based on the premise that a radiator core support upper 1a that supports the upper portion of the radiator is provided on the vehicle body side. Therefore, the invention cannot be applied to a vehicle body to which this part is not attached.

  Further, in the invention described in Patent Document 2, it is possible to tilt the radiator 20 after temporarily assembling it. However, at that time, the means for restricting the movement of the radiator 20 in the thickness direction is not sufficient. Therefore, the radiator 20 in the temporarily assembled state may be tilted more than necessary.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a support structure for a vehicle heat exchanger that efficiently holds a heat exchanger in a temporarily assembled state. Yes.

  The support structure for a vehicle heat exchanger according to the present invention is a support structure for a vehicle heat exchanger that tentatively supports the vehicle heat exchanger with respect to the vehicle body, and the vehicle heat exchanger has a center of gravity unevenly distributed in one direction. A holding pin that protrudes laterally from the side end of the exchanger, and a plate-like support portion that is provided on the vehicle body at a portion approaching the side end of the vehicle heat exchanger and has a main surface that contacts the holding pin The main surface of the support part is an inclined surface that is inclined downward along the one direction.

  According to the present invention, the holding pin that protrudes laterally from the side end of the vehicle heat exchanger is provided, the support plate is disposed on the vehicle body side of the portion corresponding to the holding pin, and the support plate is an inclined surface. . As a result, the heat exchanger temporarily assembled with respect to the vehicle body is tilted in one direction by its own weight, so that the holding pin on the heat exchanger side contacts the support plate on the vehicle body side, thereby heat exchange in the temporarily assembled state. The position of the vessel is fixed. Therefore, labor in the process of assembling the heat exchanger to the vehicle body is reduced.

It is a perspective view which shows the vehicle body to which the support structure of the heat exchanger for vehicles of this invention was applied. It is the perspective view which looked at the support structure of the heat exchanger for vehicles of the present invention from the body inside. It is a perspective view which shows the structure by which the heat exchanger for vehicles is supported by the support structure of the heat exchanger for vehicles of the present invention, (A) shows the state before the assembly, and (B) shows the state after the assembly. Show. It is a perspective view which shows the condition where the vehicle heat exchanger is assembled | attached regarding the support structure of the vehicle heat exchanger of this invention, (A) to (D) has shown this condition sequentially.

  Below, the support structure of the heat exchanger for vehicles of this form is explained. In the following description, the left side and the right side indicate the case where the vehicle body 10 faces the traveling direction.

  As shown in FIG. 1, a radiator 20 (vehicle heat exchanger) is assembled near the front end of the vehicle body 10.

  In this embodiment, the vehicle body 10 is a vehicle body of a passenger car. The vehicle body 10 is formed by welding or bonding a plurality of steel plates pressed into a predetermined shape at predetermined locations.

  The vicinity of the front end of the vehicle body 10 has an opening shape into which the radiator 20 can be incorporated. Specifically, the lower portion 12 that extends in the left-right direction below the radiator 20, the side portion 14 that extends in the vertical direction at a position approaching the right end portion of the radiator 20, and the left end portion of the radiator 20 approach. The radiator 20 is supported by the side portion 16 that extends vertically at the position. In the vehicle body 10 of this embodiment, in the assembly process of the radiator 20, a support portion that supports the upper side of the radiator 20 is not formed.

  The radiator 20 has a function of releasing heat from the heated cooling water to the outside. Although not shown, the radiator 20 has fins that are arranged so that a plurality of tubes through which the cooling water flows extend in the vertical direction or the horizontal direction and are thermally coupled to the tubes. Further, a tank in which water flowing through the tube is stored is disposed at the upper and lower ends or the left and right ends of the radiator 20. Each of these elements is held by a bracket (not shown) from four directions. The radiator 20 has a center of gravity on the rear side. Therefore, if the radiator 20 is temporarily incorporated into the vehicle body 10 without taking any measures in the vehicle assembly process, the radiator 20 falls backward. Therefore, although the support structure of the radiator 20 in the temporarily assembled state becomes a problem, in this embodiment, this problem is solved by providing a support structure on the side portion 16 as described later. Such a support structure will be described later with reference to FIG.

  FIG. 2 is a perspective view of the side portion 16 of the vehicle body as viewed at the angle indicated by the arrow A shown in FIG. With reference to this figure, a support portion 22 is formed on a side surface of the side portion 16 of the vehicle body 10 facing rightward. The support portion 22 is formed on the side portion 16 as a flat inclined surface whose rear is disposed below the front. The role of the support portion 22 is to temporarily hold the above-described radiator 20 in the assembly process and prevent the radiator 20 from overturning.

  In this embodiment, the support portion 22 is formed by bending a part of the bracket 18. Specifically, the bracket 18 is a member for assembling the ABS sensor to the vehicle body 10, and is fixed to the side portion 16 by fastening means such as screws, welding or adhesion. The bracket 18 is made of a sheet metal processed metal plate, and is disposed across the rear side surface of the side portion 16 and the right side surface. The support portion 22 is formed by bending a part of the front end portion and the lower end portion of the bracket 18 at a substantially right angle.

  In this embodiment, the support portion 22 is not a dedicated component for supporting the radiator 20 in the assembly process, but is a part of the bracket 18 that supports the ABS sensor. Therefore, the increase in cost is suppressed because the number of parts is not increased.

  With reference to FIG. 3 and FIG. 4, a method of incorporating the above-described radiator 20 into the vehicle body will be described.

  With reference to FIG. 3, first, a method of assembling the radiator 20 to the vehicle body 10 will be described. 3 is a perspective view when the radiator 20 is viewed from the viewpoint of the arrow C shown in FIG. 1, and (A) and (B) sequentially show a state in which the radiator 20 is assembled.

  3A and 3B, when assembling the radiator 20 to the vehicle body 10, first, the concave rubber mount 26 disposed in the lower portion 12 of the vehicle body 10 is disposed at the lower end of the radiator 20. Insert the protruding part. In this step, the radiator 20 is temporarily assembled with its upper portion inclined rearward.

  The rubber mount 26 is provided at a position corresponding to the left end portion of the radiator 20, is made of a resin material formed in a substantially cylindrical shape, and is fitted into an opening provided on the upper surface of the lower portion 12. Also, in the vicinity of the right end portion of the radiator 20, a rubber mount 26 is provided on the upper surface of the lower portion 12, similarly to the left end portion thereof, and a protrusion provided on the lower end of the radiator 20 on the rubber mount 26. Is inserted.

  The support structure using the rubber mount 26 described above is not for assembling the position of the radiator 20 to the vehicle body 10 but for temporarily fixing the lower end of the radiator 20. In addition, the center of gravity center in the front-rear direction of the radiator 20 is biased to the rear rather than the center. Therefore, if only the temporary support by the rubber mount 26 is relied on in the assembly process of the radiator 20, the radiator 20 falls over backward. Further, if the worker performs the assembly work while supporting the radiator 20 in order to prevent the overturn, workability in the assembly process is degraded. Therefore, in this embodiment, the holding pin 24 is provided on the radiator 20 side, and the holding pin 24 is engaged with the support portion 22 formed on the vehicle body 10, thereby preventing the radiator 20 from being overturned in the assembly process. ing.

  The holding pin 24 is formed as a protrusion protruding leftward from the vicinity of the upper end of the left side of the radiator 20. As the specific shape of the holding pin 24, a shape that is easy to move along the inclined surface of the support portion 22 is adopted, for example, a cylindrical shape having an axis in the left-right direction. Since a tank and a bracket for holding the tank are generally arranged on the left side of the radiator 20, the holding pin 24 can be attached to these. Further, the holding pin 24 may be configured by projecting a part of the tank or the bracket to the left. As the material of the holding pin 24, any of a metal material and a resin material can be adopted.

  The support portion 22 described above is formed on the side portion 16 on the vehicle body 10 side, and the positions of the holding pin 24 and the support portion 22 correspond to each other. That is, when the radiator 20 is temporarily assembled on the rubber mount 26, the vertical positions of the holding pin 24 and the support portion 22 are substantially coincident. Further, the holding structure including the holding pin 24 and the support portion 22 may be formed only at a location corresponding to the left end of the radiator 20 or may be formed at a location corresponding to the left and right ends of the radiator 20.

  After the above-described insertion of the radiator 20 is completed, the radiator 20 is tilted forward with the inserted portion as a fulcrum. Then, the holding pin 24 of the radiator 20 comes into contact with the inclined surface of the support portion 22 provided on the side portion 16.

  With reference to FIG. 4, the step of temporarily fixing the radiator 20 using the holding pin 24 will be described in detail. 4 is a perspective view of the radiator 20 and the support portion 22 as viewed from the viewpoint indicated by the arrow B in FIG. 1, and sequentially shows steps in which the radiator 20 is temporarily fixed.

  With reference to FIG. 4A, when the upper portion of the radiator 20 is pressed forward, the holding pin 24 protruding from the side surface of the radiator 20 comes into contact with the upper surface which is the inclined surface of the support portion 22.

  Here, the relative positional relationship between the support portion 22 and the holding pin 24 will be described. With the radiator 20 temporarily fixed to the main body, the vertical position of the holding pin 24 is located above the lower end of the support portion 22 and below the upper end of the support portion 22. Thereby, as will be described later, an effect of supporting the holding pin 24 by the support portion 22 and preventing the radiator 20 from overturning is exhibited.

  After the holding pin 24 of the radiator 20 comes into contact with the support portion 22, when the radiator 20 is further pressed forward, the holding pin 24 moves forward and obliquely upward along the inclined surface of the support portion 22. Accordingly, the radiator 20 moves in the same manner. Further, as described above, the lower end protrusion of the radiator 20 is inserted into the rubber mount 26 shown in FIG. 3, but the inserted state is maintained during this movement.

  With reference to FIG. 4B, when the forward pressing of the radiator 20 is continued, the holding pin 24 moves diagonally upward and forward while sliding on the upper surface of the support portion 22. The holding pin 24 moves to a position in front of and above the upper end of the support portion 22 after getting over the upper end of the support portion 22. At this time, the support force of the support portion 22 does not act on the holding pin 24. It is up to this step that the forward pressing force by the worker is required, and the radiator 20 moves by its own weight after the next step.

  Next, referring to FIG. 4C, the holding pin 24 that has lost the support force by the support portion 22 falls downward due to the dead weight of the radiator 20. At this time, the vertical position of the holding pin 24 is lower than the upper end of the support portion 22 and higher than the lower end of the support portion 22.

  Next, referring to FIG. 4D, since the center of gravity of the radiator 20 is unevenly distributed rearward, the radiator 20 is inclined rearward with the lower end thereof as the center of rotation. As a result, the holding pin 24 comes into contact with the lower surface of the support portion 22, and the radiator 20 does not tilt further. Thereby, the position when the radiator 20 is temporarily assembled is fixed. Therefore, even if the worker removes his / her hand from the radiator 20, the radiator 20 does not fall backward. Therefore, since the worker can perform other work without supporting the radiator 20, workability of the outfitting process is improved.

  After the above steps are completed, the radiator 20 is attached to the vehicle body by attaching a body part having an upper-side fixing portion of the radiator 20.

  The above-described embodiment can be modified as follows, for example.

  In the said form, although the radiator was illustrated as a heat exchanger for vehicles, a capacitor | condenser may be employ | adopted as a heat exchanger for vehicles.

  With reference to FIG. 2, the shape of the support portion 22 in plan view is a rectangular shape having long sides in the front-rear direction. However, for example, this shape may be a shape with a narrow front width.
