Description

  The present invention relates to a battery support structure that supports a battery of a vehicle.

  A battery for supplying power to various electrical components is mounted in the engine room of the vehicle. Conventionally, a battery is mounted on a battery receiving portion (battery receiving plate) supported by a battery bracket, and a pair of press plates straddling the battery and connected to both ends of the press plate. It is clamped and held by the fastening rod.

  On the other hand, Patent Document 1 includes a first bracket welded to a damper housing as a battery bracket, and a second bracket connected to the first bracket and the battery receiving portion, and supports the battery receiving portion in a cantilever state. A battery support structure is disclosed.

  However, in the battery support structure of Patent Document 1, when the vehicle is suddenly braked or turned sharply, a large overturning load acts on the battery as an inertial force, and the connection portion of the second bracket of the battery receiving portion is caused by this overturning load. Rotational moment acts on. Since the battery receiving part is supported in a cantilevered state, a large rotational moment acts on the connection part of the battery receiving part and the second bracket, and the battery receiving part is deformed by this rotational moment. There was a risk that it could not be held stably.

  Further, when the height dimension of the battery is increased, the position of the center of gravity of the battery is increased, and the moment acting on the battery receiving portion is increased, resulting in restrictions on the shape and size of the battery.

  On the other hand, in Patent Document 2, the battery is installed between the leg portion fastened to the front side frame and the damper housing and the leg portion connected to the outside of the front side frame in the vehicle width direction. There is disclosed a battery support structure including a battery receiving portion to be mounted, and an outer end portion of the battery receiving portion in the vehicle width direction being fastened to the damper housing in the vehicle width direction.

  In this battery support structure, the battery receiving part is fastened with bolts and nuts along the same direction (tangential direction) as the direction of the moment acting in the vehicle width direction due to the inertial force acting on the battery. The fastening force of the bolt and nut effectively acts in the direction of canceling out the moment.

  Thereby, in the battery support structure described in Patent Document 2, even if the height of the battery is large and the center of gravity of the battery is far from the center of rotation of the moment, the deformation of the battery receiving portion is suppressed and the battery is stabilized. Can be held.
