Protective support, protective sleeve apparatus and control method thereof

A protective sleeve apparatus, comprising:

• a protective sleeve, the protective sleeve including:
• a backplane, comprising a front side that is able to carry a backshell for attaching to a display device, a rear side opposite to the front side, and a supporting side arranged between the front side and the rear side that enables the backplane to be supported at an arbitrary angle to a datum plane;
• a hinge assembly, layable flat on the datum plane and flexibly connected with the backplane, so that the hinge assembly and the backplane are flippable relative to each other, and the hinge assembly and the front side of the backplane are opposite to each other when the hinge assembly is flipped in a direction close to the backplane to a limit position;
• a connecting assembly, arranged on the backplane and slidable relative to the supporting side of the backplane, wherein the connecting assembly is used for detachably connecting the backshell so that the backshell is rotatable relative to the backplane and
• the backshell, arranged on the front side of the backplane and detachably connected with the connecting assembly, wherein the backshell is attachable to the display device, and the backshell is rotatable relative to the backplane through the connecting assembly;
• a first driving module, used for driving the connecting assembly, so that the connecting assembly drives the backshell slidable relative to the supporting side of the backplane;
• a second driving module, used for driving the connecting assembly, so that the connecting assembly drives the backshell rotatable relative to the backplane;
• and
• a main control unit, electrically connected with the first driving module and the second driving module respectively;
• wherein, the main control unit is used for judging whether the backshell is in a preset position away from the supporting side according to a first instruction received, and controlling the first driving module when judging that the backshell is not in the preset position, so that the first driving module drives the connecting assembly to move in a direction away from the supporting side;
• and the main control unit is further used for controlling the second driving module when judging that the backshell is in the preset position, so that the second driving module drives the connecting assembly to drive the backshell to rotate into a vertical state;
• and
• the main control unit is used for judging whether the backshell is in an initial position close to the supporting side according to a second instruction received, and controlling the first driving module when judging that the backshell is not in the initial position, so that the first driving module drives the connecting assembly to move in a direction close to the supporting side;
• and the main control unit is further used for controlling the first driving module when judging that the backshell is in the initial position, so that the first driving module drives the connecting assembly to drive the backshell to rotate into a transverse state.
