Abstract:
1. A support apparatus for supporting an electronic device on a supporting surface, the support apparatus comprising: a shell configured to receive the electronic device, the shell defining an elongated sliding rail; and a back-support comprising: a prop seat detachably engaged in the sliding rail and slidable in the sliding rail upon application of an external force; and a prop stand having one side rotatably engaged in the prop seat and serving as a spindle, and at least another side fixed relative to the spindle and capable of being switched between a folded state in which the at least another side is substantially coplanar with the prop seat and a supporting state in which the at least another side is angled relative to the prop seat and serves as at least a supporting side, the switching executable by rotating the at least another side in unison with rotating the spindle in the prop seat; wherein when the at least another side of the prop stand is angled relative to the prop seat, a tilt angle of the electronic device on the supporting surface is adjustable by sliding the prop seat in the sliding rail, the prop seat comprises a base, a sliding unit and a first fixing unit, the base comprises an elongated receiving groove having the spindle of the prop stand rotatably received therein and at least one limiting member bounding part of the receiving groove to help hold the spindle of the prop stand in the receiving groove, the sliding unit is slidable along the sliding rail, the sliding rail comprises a second fixing unit, and the prop seat is capable of being held at a desired position in the sliding rail by cooperation of the first fixing unit with the second fixing unit, the first fixing unit is located at a top of the base of the prop seat, and comprises two elastically deformable hooks extending away from each other, the sliding rail defines a sliding groove, the sliding groove is bounded by two opposite long sidewalls, a top end of each sidewall comprises a plurality of teeth, and the teeth of both sidewalls cooperatively serve as the second fixing unit of the sliding rail, and when the two hooks of the prop seat are slid along the teeth of the second fixing unit to a desired position, the teeth hold the hooks in the desired position so that the prop seat is held at the desired position in the sliding rail, the sliding unit comprises two sliding plates extending from two opposite elongated sides of the base, each sidewall of the two opposite long sidewalls of the sliding groove defines a slot, and the sliding plates are slidably engaged in the slots such that the prop seat is slidable in the sliding rail, an end portion of each sliding plate near the top of the base is thinner than a remaining main portion of the sliding plate, and an end portion of each slot at the second fixing unit is narrower than a remaining main portion of the slot, the narrower end portion of each slot corresponds to the thinner end portion of a respective sliding plate, and the remaining main portion of said each slot corresponds to the remaining main portion of the respective sliding plate.
