Abstract:
1. An apparatus configured to hold a battery, the apparatus comprising: a chassis, the chassis being configured to house electronics, the electronics being configured to receive power from a battery; a first rail and a second rail substantially parallel to the first rail, the first rail and the second rail being coupled to the chassis, the first rail including a first cutout and a second cutout, the first cutout and second cutout being spaced apart from one another, and the second rail including a third cutout and a fourth cutout, the third cutout and the fourth cutout being spaced apart from one another; and a housing configured to be removably coupled to the chassis, the housing having a first side and a second side, the first side of the housing having a first protrusion and a second protrusion, the second side of the housing having a third protrusion and a fourth protrusion, the first cutout being configured to receive one of the first protrusion and the second protrusion during vertical movement of the housing relative to the chassis and the third cutout is configured to receive one of the third protrusion and the fourth protrusion during vertical movement of the housing relative to the chassis, the housing being slidable in a substantially lateral motion under the first rail and the second rail, whereby motion in a vertical direction substantially perpendicular to the lateral motion is prevented by the first rail and the second rail being disposed over at least the first protrusion and the third protrusion; wherein the housing can engage the chassis by a first substantially vertical relative motion there between such that at least one of the protrusions lowers through at least one of the cutouts, followed by a horizontal relative motion there between such that the protrusions at least partially overlap with the rails, such overlap preventing further horizontal relative motion between the housing and the chassis.
