In a state that the base 12 is separated from the display screen 2, the base 12 may be attached to the back surface of the display screen 2 through the third magnetic unit 71 and the fourth magnetic unit 72, so that the portable electronic device may be convenient to carry.

By the technical scheme, the invention has the beneficial effects that:

1. the disassembly and assembly of the base 12 and the display screen 2 can be easily realized;

2. the display screen 2 system can be provided with a plurality of adjusting joints, so that the requirements of various positions, angles and postures of different people can be met;

3. the electrical connection 665 provided between the display 2 and the base 12 not only serves as an interface for electrical transmission, but also serves as a guide during insertion of the first and second poles.

As shown in connection with fig. 14, 15 and 16, in a preferred embodiment, the base 12 is removably disposed on the display screen 2. The display screen 2 has a display surface and a back surface opposite to the display surface, the back surface of the display screen 2 is provided with a third magnetic unit 71, and a bottom wall of the base 12 is provided with a fourth magnetic unit 72 that can be adsorbed by the third magnetic unit 71.

With the above structure, when the base 12 is removed from the display screen 2, the base 12 can be adsorbed on the third magnetic unit 71 of the display screen 2 through the fourth magnetic unit 72, so that an operator only needs to clamp or grasp the display screen 2 with one hand in the carrying process to carry the display. The display structure in this state of fig. 14 is ultra-thin. For example, the thickness in this state does not exceed 13 mm.

In particular, the display screen 2 may have a plate shape, similar to the prior art. The display screen 2 has a display surface and a front surface opposite to the display surface. The display screen 2 includes a display frame and a liquid crystal screen disposed in the display frame. In the energized state, the display screen 2 can output interfaces such as characters and pictures outwards through the front face of the liquid crystal screen. The third magnetic attraction unit 71 is provided inside the back surface of the display screen 2, that is, between the back surface of the display screen 2 and the liquid crystal panel, whereby the back surface of the display frame can be made smooth and flat. Correspondingly, the fourth magnetic unit 72 is disposed on an inner sidewall of the bottom wall of the base 12 (i.e., a bottom wall located in the base 12). Thereby, the bottom wall of the base 12 can be made smooth and flat.

In order to improve the adsorption force between the third magnetic unit 71 and the fourth magnetic unit 72 and avoid the false detachment between the base 12 and the display screen 2, the number of the fourth magnetic units 72 is plural, and the plural fourth magnetic units 72 are distributed around the bottom wall of the base 12.

In a preferred embodiment, the back of the display 2 is provided with a first support unit comprising a first connection unit 51 in rotational connection with said display 2 and a second connection unit 52 in pivotal connection with said connection 5. Thereby, the first support unit can be attached to the display screen 2 by the second connection unit 52, thereby further reducing the volume occupied by the display screen 2 when carried.

In particular, the thickness of the base 12 is not greater than the thickness of the first support unit. Thus, when the base 12 is in an adsorption state with the back surface of the display screen 2 and the first supporting unit is attached to the back surface of the display screen 2, the base 12 does not protrude from the first supporting unit.

The display further comprises a vertical bar 11 rotatably connected to the base 12. The longitudinal bar 11 is detachably connected to the second connecting unit 52 by means of a plug-in connection 61. For example, the free end of the longitudinal bar 11 is provided with a protruding portion and the free end of the second connection unit 52 is provided with a socket groove cooperating with said protruding portion of the longitudinal bar 11. The top of the base 12 is provided with a groove 121 for folding the vertical rod 11 when the vertical rod 11 is separated from the first supporting unit and is in a separated state. A stopper 122 for limiting the protruding portion when the vertical rod 11 is in the folded state is arranged in the groove 121. In this way, the thickness of the longitudinal bars 11 and the base 12 in the collapsed state can be further reduced so that the thickness of the base 12 and the longitudinal bars 11 together is not greater than the thickness of the first supporting unit.

In the present embodiment, the bottom wall of the base 12 is rectangular. Of course, in alternative embodiments, the bottom wall of the base 12 may be circular, oval, square, or other regular or irregular shapes as desired.

The base 12 has two opposite long sides and two opposite wide sides, the number of the fourth magnetic units 72 is four, and the number of the fourth magnetic units 72 in four groups is respectively set on the two long sides and the two wide sides; the number of the third magnetic attraction units 71 is three, wherein two groups of the third magnetic attraction units 71 are used for corresponding to two groups of the fourth magnetic attraction units 72 arranged on the long side of the base 12, the other group of the third magnetic attraction units 71 are positioned at the center of the width direction of the display screen 2, and the other group of the third magnetic attraction units 71 are used for corresponding to one group of the two groups of the fourth magnetic attraction units 72 arranged on the wide side of the base 12. The number of the fourth magnetic attraction units 72 of the third magnetic attraction units 71 of each group may be 1, 2, 3 or other numbers.

Thereby, the third magnetic attraction unit 71 is located at the side of the display screen 2, and the chassis 12 is completely covered by the display screen 2 when the chassis 12 is attached to the display screen 2. Meanwhile, the chassis 12 may be firmly attached to the back surface of the display screen 2, and the orientation of the width sides of the chassis 12 may not be limited. The number of the third magnetic units 71 is only three, so that on one hand, in order to reduce the cost, on the other hand, the base 12 can be limited to have a width edge located in the middle of the display screen 2, so that the base 12 is prevented from being partially located outside the display screen 2, and further, damage is prevented from being caused in the carrying process.

By the technical scheme, the beneficial effect of this application lies in:

1. in the carrying process, an operator can carry the display by clamping or grabbing the display screen 2 by a single hand;

2. the base 12 and the display screen 2 can be ensured to be flat and smooth;

3. the volume is smaller in the carrying process;

4. the adsorption force is large, and the direction of the width edge of the base 12 is not limited;

5. while reducing costs, it is ensured that the base 12 is located within the confines of the display screen 2 during carrying.
