Abstract: An on-vehicle holder of a portable electronic display device comprises a support bracket, a U-shaped base and a movable engagement member. The U-shaped base is connected to the support bracket, comprising a first lateral plate, a second lateral plate and a bottom plate connecting together; a containing space portion is made by the first lateral plate, the second lateral plate and the bottom plate. The movable engagement member comprises an operating portion and a fastener portion. In addition, at least either the length of the first lateral plate or the length of the second lateral plate is longer than the width of the bottom plate. Consequently, the structure of the invention is made to contain the thickness of a portable electronic display device to achieve the objective of design miniaturization.

Abstract: A buffer apparatus for a ceiling screen includes a case and a lid pivotally coupled with one lateral end of the case for holding a screen. The lateral end has two sides forming a first action side and a second action side that correspond to each other. The first action side has a speed reducing mechanism to reduce the flipping speed of the lid and provide a buffer effect when the lid is driven by a first elastic element and unfolds. The second action side has a second elastic element compressed by the flipping lid at the initial unfolding stage during the buffering process, and expanded at a later unfolding stage of the lid to provide a returning elastic force to move and anchor the lid on a desired position. Thus the impact and vibration resulting from fast flipping of the lid may be prevented.
