TECHNICAL FIELD OF THE INVENTION
The present invention relates generally to a display device, and more particularly to a mobile display device.
DESCRIPTION OF THE PRIOR ART
Movable television sets are available in the market, such as Taiwan Utility Model M536310. The Utility Model, as shown in FIG. 1 thereof, is generally made up of a main body and an elevation mechanism. The main body includes a first receiving portion, a first horizontal rail, a guide channel, and a connecting block. The elevation mechanism is arranged in the first receiving portion, and elevation mechanism includes two vertical rail sets, a movable link assembly, a linear actuator, and a carrier unit. By means of combination of such components, the Utility Model realizes elevation and lowering of a display on the carrier unit.
Although an effect of elevation and lowering of the display, it has to be arranged at a location close to a wall socket, or an extension cord must be used for operation at a location far away from the wall socket. This arrangement makes the extension cord vulnerable to influence of external forces (such as being treaded or run over) to thereby cause the extension cord to break. Further, as the total weight includes the display, the main body, and the elevation mechanism, implementation of moving or transporting is inconvenient.
SUMMARY OF THE INVENTION

To achieve the above objective, the present invention provides a mobile display device, which comprises:
- a movable base, the movable base comprising a first receiving space and a second receiving space, the movable base comprising a back board, the movable base comprising a bottom board, the bottom board being provided with a plurality of movement casters, the movable base comprising a top board, the top board being formed with an opening, the movable base comprising two lateral boards, the movable base comprising a first movable shielding cover, the first movable shielding cover being arranged between the two lateral boards and adjacent to the bottom board;
- an elevation device, the elevation device being arranged in the second receiving space, the elevation device being fixed to the bottom board, the elevation device comprising an extendible/contractable rod, the elevation device being provided with a display device, the display device being arranged on the extendible/contractable rod, the display device being movable vertically by means of the extendible/contractable rod to extend through the opening to an outside of the movable base; and
- a plurality of electrical power supply devices, the electrical power supply devices being arranged in the first receiving space, the electrical power supply devices supplying electrical power to the elevation device and the display device, wherein due to arrangement of the plurality of electrical power supply device, operation time of the elevation device and the display device are extended.
By arranging the electrical power supply devices in the first receiving space, and the electrical power supply devices supplying electrical power to the elevation device and the display device, the display device is allowed to move in the vertical direction through the opening to achieve an effect of arbitrarily placing the movable base at any random location without being located around an electrical socket, and the bottom board is provided with the plurality of movement casters to achieve an effect of easy mobility.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1, 2, and 3, a mobile display device, comprises:
- a movable base 1, wherein the movable base 1 is formed with a first receiving space 16 and a second receiving space 17, and the movable base 1 comprises a back board 11, and the movable base 1 comprises a bottom board 12, the bottom board 12 being provided with a plurality of movement casters 121, and further, the movable base 1 comprises a top board 13, the top board 13 being formed with an opening 131, and the movable base 1 comprises two lateral boards 14, and further, the movable base 1 comprises a first movable shielding cover 15, the first movable shielding cover 15 being arranged between the two lateral boards 14 and adjacent to the bottom board 12,
- wherein the first movable shielding cover 15 can be a slide door or other openable door arrangements; and
- an elevation device 2, wherein the elevation device 2 is arranged in the second receiving space 17, and the elevation device 2 is fixed to the bottom board 12, and the elevation device 2 comprises an extendible/contractable rod 21, and further, the elevation device 2 is provided with a display device 22, the display device 22 being arranged on the extendible/contractable rod 21, the display device 22 being movable vertically by means of the extendible/contractable rod 21 to extend through the opening 131 to an outside of the movable base 1,
- wherein the opening 131 is provided with a second movable shielding cover 1311, and the second movable shielding cover 1311 can be a lift cover, so that to extend the display device 22 through the opening 131, the second movable shielding cover 1311 can be opened to allow the extension of the display device 22 through the opening 131, and to retract the display device 22 back into the movable base 1, the second movable shielding cover 1311 can be closed in combination therewith, in order to prevent foreign objects from falling into the movable base 1 and to achieve effects of dust prevention and protection (as shown in FIGS. 3 and 4),
- wherein the elevation device 2 is mounted on the back board 11 so as to more securely fix the elevation device 2,
- wherein the elevation device 2 may comprise a chain-sprocket mechanism or an electrically driven push rod mechanism or a hydraulically driven push rod or a screw-based push rod, and
- wherein the display device 22 comprises a display screen; and
- a plurality of electrical power supply device 3, wherein the electrical power supply devices 3 are arranged in the first receiving space 16, and the electrical power supply devices 3 are operable to supply electrical power to the elevation device 2 and the display device 22, and to extend operation time of the elevation device 2 and the display device 22,
- wherein a partition board 18 is arranged between the first receiving space 16 and the second receiving space 17, and
- wherein the electrical power supply devices 3 may comprise an all-solid-state battery, and compared to a known lithium ion battery, the all-solid-state battery can be charged rapidly, has an extended service life, and is durable for low temperature to high temperature, and has a high degree of freedom for shape and a larger capacity and power.
