Battery unit holding device for vehicle
First Claim
1. A battery unit holding device for a vehicle that holds a battery unit in place in the lower part of a body of the vehicle, comprising:
- a fixing part that is provided in one of the vehicle body and the battery unit;
a fixed part that is provided in the other of the vehicle body and the battery unit and to be fixed on the fixing part; and
a positioning part that is to be provided between the vehicle body and the battery unit for positioning the battery unit to the vehicle body, whereinthe fixed part includes a support shaft that extends in a first direction that corresponds to one of a longitudinal direction and a width direction of the vehicle body for supporting load acting downwardly on the battery unit;
the fixing part is movable in the first direction along the support shaft while holding the support shaft at a middle position of the support shaft;
the positioning part is configured to permit the fixing part to move in the first direction along the support shaft from the middle position of the support shaft when a first impact that is greater than a first preset force is applied to the vehicle body in the first direction,wherein the positioning part includes;
a first bracket having a U-shaped cross section as viewed in the first direction that is fixed on the vehicle body and extended away from the vehicle body and a second bracket having a U-shaped cross section as viewed in the first direction that is fixed on the battery unit and extended away from the battery unit;
a positioning pin that is fixed to one of the vehicle body and the battery unit;
a first positioning hole formed in the first bracket through which the positioning pin is configured to be inserted so that a middle part of the positioning pin is secured into the first positioning hole without free play; and
a second positioning hole formed in the second bracket through which the positioning pin is to be inserted; and
whereinthe positioning part is configured such that, when the first impact is applied to the vehicle body in the first direction, the first bracket moves with respect to the second bracket in the first direction and the first positioning hole deforms into an elongated hole that is elongated in the first direction and at least one of the first positioning hole, the second positioning hole, and the positioning pin is deformed or broken.

Abstract
A battery unit holding device that holds a battery unit in place includes a fixing part, a fixed part, and a positioning part provided between the vehicle body and the battery unit for positioning the battery unit on the vehicle body. The fixed part has a support shaft extending in a first direction that corresponds to one of a longitudinal direction and a width direction of the vehicle body and supports the load acting downwardly on the battery unit. The fixing part is movable along the support shaft while holding the support shaft at a middle position thereof. When a first impact greater than a first preset force is applied to the vehicle body in the first direction, the positioning part permits the fixing part to move in the first direction along the support shaft from the middle position of the support shaft.
