Since the planet carrier 52 and the steady member 53 are fixed to the computer main unit 10, the rotational force can be transmitted to the ring gear 54 through the planet gear 56, the ring gear 54 rotates in the opposite direction to the main screen 20 and the sun gear 55, and the rotational speed of the ring gear 54 is determined by the gear ratio of the sun gear 55 and the ring gear 54. Since the ring gear 54 is connected to the sub-screen 30, the rotational force can be transmitted to the sub-screen 30 through the ring gear 54, and the rotational direction and rotational speed thereof are the same.

Thus, when the primary screen 20 rotates, the secondary screen will rotate in the opposite direction, with the speed of rotation determined by the gear ratio of the sun gear 55 to the ring gear 54.

For example, when the user opens the main screen 20 of the dual-screen notebook computer, the generated driving force is transmitted to the sub-screen 30 through the rotating shaft structure 50, so that the sub-screen 30 rotates in the opposite direction with respect to the main screen 20, and the transmission ratio thereof may be 2 to 1. When the main screen 20 is turned to 120 °, the sub-screen 30 is turned to 60 ° in the reverse direction. When the main screen 20 is continuously turned to 135 degrees, the auxiliary screen keeps 60 degrees unchanged and is not continuously turned. When the main screen 20 is closed, the sub screen 30 is maintained at 60 ° when the main screen 20 is closed from 135 ° to 120 °. When the main screen 20 is turned over from 120 ° to 0 °, the sub-screen 30 is turned over from 60 ° to 0 ° in the reverse direction.

Please refer to fig. 14a-14d, which are usage status diagrams of the dual-screen notebook computer according to the embodiment of the present application.

As shown in fig. 14a, when the dual-screen notebook computer is in a closed state, the operation interface of the sub-screen 30 is on the appearance surface, and the user can operate the sub-screen 30 while the main screen 20 is closed. As shown in fig. 14b, the main screen 20 is flipped clockwise to 40 ° and the sub-screen 30 is flipped counterclockwise to 20 ° in linkage. As shown in fig. 14c, the main screen 20 is flipped clockwise to 80 ° and the sub-screen 30 is flipped counterclockwise in a linked manner to 40 °. As shown in fig. 14d, the main screen 20 is flipped clockwise to 120 ° and the sub-screen 30 is flipped counterclockwise to 60 ° in linkage. In the above-mentioned opened state of fig. 14d, the sub-screen 30 and the main screen 20 are in the same operation plane direction, and the user can simultaneously operate on the main screen 20 and the sub-screen 30.

It can be seen from fig. 14a to 14d that the main screen 20 is turned to 120 ° clockwise during the opening change of the dual-screen notebook, and the sub-screen 30 is driven by the rotating shaft structure (planetary gear set) to be turned to 60 ° counterclockwise from 0 °.

It can be seen from fig. 14d to 14a that the main screen 20 is turned to 0 ° counterclockwise during the closing change of the dual-screen notebook computer, and the sub-screen 30 is driven by the rotating shaft structure (planetary gear set) and turned to 0 ° clockwise from 60 °.

By adopting the dual-screen notebook computer provided by the embodiment of the application, the main screen 20 can be turned over under the action of external force, and the force is transmitted to the auxiliary screen 30 through a mechanical structure, so that the auxiliary screen 30 is turned over in the opposite direction relative to the main screen 20, and therefore when the dual-screen notebook computer is in a closed state, the operation interface of the auxiliary screen 30 is on the appearance surface and can be operated; when the dual-screen notebook computer is in an open state, the operation interface of the secondary screen and the operation interface of the main screen 20 are in the same direction, and can be operated simultaneously. The embodiment of the application has the advantages of simple structure, convenience in use and capability of improving the experience of a user.

It will be evident to those skilled in the art that the present application is not limited to the details of the foregoing illustrative embodiments, and that the present application may be embodied in other specific forms without departing from the spirit or essential attributes thereof. Therefore, appropriate changes and modifications to the above embodiments are intended to be included within the scope of the present invention as claimed, and within the spirit and scope of the present invention.
