Specific embodiment
Below in conjunction with the attached drawing in invention embodiment, the technical solution in invention embodiment is carried out clear, complete
Site preparation description.
Fig. 1, Fig. 2 and Fig. 3 are please referred to, a kind of flexible screen support construction 100 of offer, the flexible screen support construction are provided
100 include：
Pedestal 10, including main body 11 and the spool 12 for being rotationally connected with the main body 11, the spool 12 to coiling or
Flexible display screen 1 is unfolded；
Actuator 20 is fixed in the main body 11, to drive the spool 12 to turn to A rotation along first；
Torsion spring 30 is connected to the main body 11 and the spool 12, turns to a along second to provide the spool 12
The torsional forces of rotation, the second steering a are reversed with the first steering A.
It is understood that the flexible screen support construction 100 is applied to mobile terminal, the flexible display screen 1 is with institute
The rotation of spool 12 is stated in coiling or unfolded state.The flexible display screen 1, which can be, turns to A turns along first in the spool 12
It is in unfolded state when dynamic, when turning to a rotation along second in around volume state, it is of course also possible to be in the spool 12 along first
It is in around volume state when turning to A rotation, is in unfolded state when turning to a rotation along second.The mobile terminal can be mobile phone, plate
Computer or laptop etc..
The spool 12 is driven to turn to A rotation along first by the actuator 20, and the torsion spring 30 is to described
Spool 12 provides the torsional forces for turning to a rotation along second, and the second steering a is reversed with the first steering A, so as to
So that the spool 12, which is only turned in the 120 driving effect lower edge first of actuator, consumes energy consumption when A is rotated, and the volume
Axis 12 can turn to a rotation along second automatically under the elastic reaction of the torsion spring 30, to reach the effect for reducing energy consumption
Fruit.The flexible screen support construction 100 can achieve the effect for reducing energy consumption when carrying out coiling or expansion to the flexible display screen 1
Fruit.
In present embodiment, the main body 11 is elongated.The width of the length direction of the main body 11 and the flexible screen 1
It is parallel to spend direction.The length direction of the spool 12 is parallel with the length direction of the main body 11, outside the spool 12
One edge of fixed 1 width direction of flexible display screen of side wall.To which the spool 12 rotation can make the flexibility aobvious
Display screen 1 is in length direction coiling or expansion.The both ends of the spool 12 are rotatably dispose in respectively in the main body 11.The main body
11 can be shell either bearing block.In other embodiments, the length direction of the main body 11 can also be with it is described
The length direction of flexible display screen 1 is parallel, the length direction side of the fixed flexible display screen 1 of the lateral wall of the spool 12
Edge, so that the flexible display screen 1 is in width direction coiling or expansion.
In present embodiment, the actuator 20 drives the spool 12 to rotate, while the spool 12 drives the torsion
Square spring 30 generates deformation, so that the torsion spring 30 stores power, i.e., the described actuator 20 drives the spool 12 along first turn
To when A (in Fig. 1 clockwise) rotation, it also is filled with deformation energy to the torsion spring 30, the torsion spring 30 will be described
The mechanical energy of spool 12, which is converted into deformation, can be carried out storage.When the actuator 20 stops acting on the spool 12, then institute
