Description

  The present invention relates to a liquid tank mounting structure. More specifically, the present invention relates to a structure for holding a liquid tank constituting an air conditioner provided in a vehicle such as an automobile on the vehicle body side.

2. Description of the Related Art Conventionally, vehicles such as automobiles are provided with an air conditioner that performs indoor cooling and dehumidification, and the air conditioner includes a condenser, an evaporator, a liquid tank, and the like. The liquid tank is supported by a support member on the vehicle body side via a mounting bracket (see, for example, Patent Document 1).
JP 2000-292029 A

  However, according to the above-described prior art, only one side of the side surface of the liquid tank is supported, and the holding strength of the liquid tank is low. Therefore, the liquid tank may vibrate when the vehicle travels. Moreover, when the harness is routed near the mounting bracket, the harness may be sandwiched between the mounting bracket and the support member.

  Therefore, the present invention provides a liquid tank mounting structure in which the holding strength of the liquid tank is high and there is no possibility that a long member such as a harness is sandwiched between the mounting bracket and the support member.

A liquid tank mounting structure according to the present invention includes a vehicle body side support member, a mounting bracket fixed to the support member and extending in a direction away from the support member, and a liquid tank held by the mounting bracket. A long member routed in the vicinity of the mounting bracket, the mounting bracket having a first bracket and a second bracket, and the first bracket is fixed to the support member. And a leg portion that bends and extends from the main body portion toward the support member, and a holding portion that extends from the leg portion and holds the liquid tank, and the second bracket is formed of the support member and the first bracket. The long member is disposed between the support member and the leg portion of the first bracket and on the outer side of the second bracket, and the support member has a plate-like support. In the panel The mounting bracket is provided on one surface of the support panel, a reinforcing panel having a closed cross section is provided at a portion corresponding to the mounting bracket on the other surface, and mounting flange portions are provided on both sides of the closed cross section of the reinforcing panel. The most main feature is that one of these mounting flanges is fixed to the first bracket via the support panel, and the other of the mounting flanges is fixed to the second bracket via the support panel. To do.

  According to the mounting structure of the liquid tank according to the present invention, since the mounting bracket in which the first bracket is reinforced by the second bracket is used, the holding strength of the liquid tank is increased. Further, even if a long member such as a harness tries to enter between the mounting bracket and the support member, the long member is blocked even when the mounting bracket swings due to vehicle travel. It is not sandwiched between the mounting bracket and the support member.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
