Fig. 1 to fig. 5 show an embodiment of an electronic device of the present invention, and it should be noted that the electronic device in this application is a mobile terminal, and may include a mobile phone, a notebook computer, a personal digital assistant, and the like. In the embodiment, only a notebook computer is taken as an example for description, and the electronic device includes a first housing 10, a second housing 20, a flexible display 30, an elastic element 40 and a transmission mechanism.
The first housing 10 has an accommodating space therein, and the material of the accommodating space may be aluminum alloy or plastic, and is not limited herein. The receiving space in the first housing 10 receives input components, such as a keyboard and a touch pad, for receiving input commands of a user. Other functional components such as a mainboard, a storage device and a battery are also accommodated in the accommodating space, so that the electronic equipment can receive input instructions, perform operation and output operation results.
The second housing 20 includes a fixed portion 21 and a movable portion 22, the movable portion 22 is movable relative to the fixed portion 21, the fixed portion 21 is rotatably connected to the first housing 10, and the fixed portion 21 has a first supporting surface 211. The moving part 22 is provided on one side of the fixed part 21 and can move toward or away from the fixed part 21.
At least one part of the flexible display screen 30 covers the first supporting surface 211, one end of the flexible display screen 30 is fixedly connected with the first supporting surface 211, and the other end of the flexible display screen 30 bypasses the edge of the moving part 22 and is located on the opposite side surface of the first supporting surface 211. The flexible display 30 can be expanded or contracted with the movement of the moving part 22.
Specifically, when the moving part 22 moves away from the fixed part 21, the flexible display screen 30 on the side opposite to the first supporting surface 211 bypasses the edge of the moving part 22 to the side of the first supporting surface 211, so that the area of the visible region is increased, i.e., the unfolding effect of the flexible display screen 30 is realized.
When the moving part 22 moves toward a direction close to the fixed part 21, the flexible display 30 on the side of the first supporting surface 211 bypasses the edge of the moving part 22 to an opposite side of the first supporting surface 211, so that the area of the visible area is reduced, i.e., the shrinking effect of the flexible display 30 is realized.
The elastic element 40 is located in the second housing 20, and two ends of the elastic element 40 are respectively connected with the fixing portion 21 and the other end of the flexible display screen 30. The elastic element 40 is used for applying a pulling force to the flexible display screen to ensure that the flexible display screen 30 is tightly attached to the edge of the moving part 22 and the first supporting surface 211. Specifically, the elastic element 40 may be provided as a plurality of extension springs, two ends of the plurality of extension springs are respectively connected to the other ends of the fixing portion 21 and the flexible display screen 30, and when the moving portion 22 moves toward the direction close to the fixing portion 21, the extension springs can also pull the flexible display screen 30 back to the opposite side surface of the first supporting surface 211 for providing the contraction force of the flexible display screen 30.
The transmission mechanism is configured to move the moving part 22 relative to the fixed part 21 in response to rotation of the second housing 20 relative to the first housing 10. Specifically, when the user lifts the second casing 20, i.e. when the second casing 20 and the first casing 10 are unfolded, the transmission mechanism can drive the moving part 22 to move towards a direction away from the fixed part 21, thereby increasing the visible area of the flexible display screen 30 when the user lifts the second casing 20. When the user closes the second casing 20, that is, when the second casing 20 and the first casing 10 are folded together, the transmission mechanism can drive the moving part 22 to move towards the direction close to the fixed part 21, so that when the user closes the second casing 20, the visible area of the flexible display screen 30 is reduced, and the area of the second casing 20 is further reduced. It will be appreciated that the display control module is capable of dynamically adjusting the resolution of the viewable area to adapt the resolution to the viewable area, for example: as the opening angle of the second housing 20 increases, the area of the visible region of the flexible display 30 increases, and the resolution of the visible region increases, whereas as the opening angle of the second housing 20 decreases, the area of the visible region of the flexible display 30 decreases, and the resolution of the visible region decreases accordingly.
It should be noted that the transmission mechanism transmits the force of the user lifting or closing the second housing 20 to the moving portion 22, so that the moving portion 22 moves away from or close to the fixed portion 21. That is, the transmission mechanism only transmits the force applied to the second housing 20 by the user to the moving portion 22 to drive the moving portion 22 to move, the transmission mechanism itself does not generate power, and the force for driving the moving portion 22 to move is provided by the user.
The electronic device of the embodiment of the invention is a folding structure, and the second housing 20 is rotatably connected with the first housing 10. When carrying, second casing 20 and first casing 10 are together folded, the effort that rotates second casing 20 with the user through drive mechanism during the use transmits to removal portion 22, move towards the direction of keeping away from or being close to fixed part 21 with drive removal portion 22, thereby realize the visual region of increase or reduction flexible display screen 30, and then realize when folding second casing 20 and first casing 10, reduce the area of second casing 20, reduce electronic equipment's whole volume, convenient to use person carries, and simultaneously, when second casing 20 expandes with first casing 10, increase the area of second casing 20, increase flexible display screen 30's display area, promote user's experience. The electronic device of the present invention does not need to provide a separate power source for the sliding and rolling action of the flexible display screen 30, and the sliding and rolling of the flexible display screen 30 can be realized only by the action of lifting or closing the second housing 20 by the user, so that the structure of the electronic device is simple, and the production cost is reduced.
