Abstract: The present invention provides a height-adjustable pillow comprising: a lower member; an upper member which is disposed above the lower member, in such a way as to be able to move vertically relative to the lower member; and a raising and lowering device for adjusting the height of the upper member by moving the upper member.

Abstract: Disclosed is an electric vehicle battery attaching/detaching device including a battery having incision recesses formed on lateral portions, respectively, each incision recess having a lower engaging ledge; a battery mounting unit adapted to detachably mount the battery, the battery mounting unit having grasping holders formed on a bottom portion and adapted to engage with or disengage from the lower engaging ledges of the battery incision recesses; and a controller adapted to rotate the grasping holders in response to an electric signal so that the grasping holders engage with or disengage from the lower engaging ledges of the battery incision recesses.

Abstract: A system for automatically exchanging a battery of an electric vehicle, the system including a horizontal frame of a predetermined area formed at a location higher than the electric vehicle; a plurality of battery stands formed on a bottom surface of the horizontal frame at a predetermined interval; a pair of fixed guide rails arranged and installed on front and rear sides or left and right sides of the horizontal frame, respectively; a variable guide rail adapted to move horizontally along X-axis or Y-axis along the fixed guide rails; a movable rail adapted to move horizontally along Y-axis or X-axis along the variable guide rail and ascend/descend vertically; and a grasping means installed on a lower end of the movable rail and adapted to pick up a battery of the electric vehicle or a battery seated on the battery stand and exchange each other.
