Description

  The present invention relates to an auxiliary equipment mounting structure for an automobile in which a cooling pump used for cooling a control device is arranged on the outer side in the vehicle width direction of a front side frame.

  A hybrid vehicle or an electric vehicle includes a drive source unit including a motor, a generator, and other components, and a control device that controls the drive source unit. Generally, the drive source unit and the control device include a dash. It is mounted in the space in front of the panel (the space corresponding to the engine room of the engine car). Further, as shown in FIG. 11, this kind of automobile 500 includes a cooling system 520 for cooling the semiconductor of the control device 518, a reserve tank 522, a cooling pump 524, and a heat that constitute the cooling system 520. The exchanger 526 is also disposed in the space 502 in front of the dash panel. In addition, the arrow shown with a dashed-dotted line in FIG. 11 has shown the flow of the cooling fluid in the cooling system 520. FIG.

  However, in the front of the dash panel, large equipment such as the drive source unit 516 and the control device 518 and various auxiliary machines are mounted in a space on the inner side in the vehicle width direction from the front side frame 504. It may be difficult to mount all the components of the cooling system 520. In particular, in the case of a hybrid vehicle, the engine 514 is also mounted in the same space, so that the space tends to be very crowded.

  Under such circumstances, the cooling pump may be installed outside the front side frame in the vehicle width direction. In this case, the cooling pump is attached to the side surface of the front side frame via a bracket, and the front side frame and a member (for example, an auxiliary machine such as a fuse box or a bumper fascia) located outside the vehicle width direction. It will be arranged in a narrow space between.

  In the cooling system, the reserve tank is disposed at the uppermost part of the cooling path in order to perform air bleeding. Therefore, the cooling pump is installed at a position lower than the reserve tank, and as shown by a two-dot chain line in FIG. 12 (virtual line indicating the installation state before the collision), the cooling pump sucks the cooling liquid supplied from the reserve tank. The suction port 576 is disposed vertically upward. In addition, a joint pipe 560 may be installed above the suction port 576 of the cooling pump 524. In this case, the joint hose 562 attached to the suction port 576 via the joint pipe 560 and the reserve tank 522 side are provided. A hose 564 is connected.

  Thus, when the suction port 576 of the cooling pump 524 arranged vertically upward and the joint pipe 560 above the suction port are connected by the joint hose 562, the distance between the suction port 576 and the joint pipe 560 is short. If too much, it becomes difficult to attach the joint hose 562 to both. Therefore, in order to secure a sufficient distance between the joint pipe 560 and the suction port 576, it is considered that the joint pipe 560 is arranged as high as possible and the cooling pump 524 is arranged as low as possible and fixed to the front side frame 504, respectively. It is done.

  However, when the cooling pump 524 is arranged low in this way, most of the cooling pump 524 may be disposed so as to protrude below the lower edge of the front side frame 504. In this case, as shown by the solid lines in FIGS. 12 and 13, the cooling pump 524 enters the lower side of the front side frame 504 at the time of a collision from obliquely forward, and is arranged on the inner side in the vehicle width direction than the front side frame 504. Since there is a possibility of hitting the side surface of the provided drive source unit 516, there remains a problem in protecting the drive source unit 516. In particular, when a connector 552 for outputting a control signal, such as a motor rotation sensor connector, is attached to the side surface of the drive source unit 516, if the connector 552 is damaged due to an impact at the time of contact with the cooling pump 524, power There is a possibility that necessary control such as blocking control may not be properly executed.

  On the other hand, Patent Document 1 discloses a configuration in which a cooling pump is disposed outside the front side frame in the vehicle width direction and a cylindrical suction port of the cooling pump is disposed forward. . When the suction port of the cooling pump is arranged in the forward direction in this way, if the joint pipe is disposed near the upper part of the cooling pump, the distance between the suction port and the joint pipe is not required even if the cooling pump is disposed low. Can be secured sufficiently. Therefore, it is possible to suppress the cooling pump from protruding below the lower end of the front side frame, thereby preventing the cooling pump from entering the lower side of the front side frame and contacting the drive source unit at the time of a collision. It becomes possible to prevent.

JP 2000-264076 A

  However, when the cooling pump is installed with the suction port facing forward as in the configuration of Patent Document 1, a long space in the front-rear direction is required for installing the cooling pump. However, when a cooling pump is disposed outside the front side frame in the vehicle width direction, for example, in front of the cooling pump, there is a space for installing lamps (fog lamps, etc.), a space for absorbing a shock by a crash can, etc. It is necessary to ensure, and since a mud guard is disposed behind the cooling pump, it is difficult to ensure a sufficient space both in front and behind. Therefore, in view of such layout circumstances, disposing the suction port of the cooling pump facing forward is extremely disadvantageous in terms of space saving in the front-rear direction.

  Therefore, in the case where the cooling pump is disposed outside the front side frame in the vehicle width direction, the present invention avoids contact of the cooling pump with the drive source unit at the time of a collision from an oblique front, It is an object of the present invention to reduce the space in the front-rear direction around the cooling pump while ensuring good workability of mounting the joint hose to the joint pipe.

  In order to solve the above-described problems, an auxiliary machine mounting structure for an automobile according to the present invention is configured as follows.
