Description

Portable electronic device with multiple screens

Technical Field

The present invention relates to portable electronic devices, and more particularly to a portable electronic device with multiple screens.

Background

Portable electronic devices such as palm top computers, hand held computers, notebook computers, personal computer tablets, and Personal Digital Assistants (PDAs) are becoming more and more popular. To provide more diversified operation and viewing modes for users, portable electronic devices including multi-screen devices are proposed. In the existing portable electronic devices with multiple screens, the two screens are mostly pivoted with each other through a connecting rod structure, so that any two screens are suitable for relative rotation and maintain opening and closing angles.

However, the link structure often causes a significant level difference between the main screen and the sub-screen of the portable electronic device with multiple screens, resulting in poor visual effect, thereby damaging the aesthetic appearance of the product. Moreover, the connecting rod structure for connecting the multiple screens is often complex, which causes inconvenient operation for users, so that the portable electronic device with multiple screens cannot provide good use experience.

Therefore, how to make the portable electronic device with multiple screens overcome the step difference between the main screen and the secondary screen to improve the overall aesthetic degree, and simultaneously have good operation flexibility and use experience is a subject which needs to be considered and solved by relevant technicians.

Disclosure of Invention

The invention is directed to a portable electronic device with multiple screens, which compensates the step difference when a second screen moves out of a first screen through a lifting mechanism, so that the portable electronic device has good operation flexibility and overall attractive appearance.

According to an embodiment of the invention, a portable electronic device with multiple screens includes a first screen and a second screen. The second screen is movably coupled to the first screen along an arc path to be received in or moved out of the first screen. The display surface of the first screen and the display surface of the second screen face in the same direction. The second screen comprises a base, a lifting mechanism and a display unit. The lifting mechanism is arranged on the base. The display unit is arranged on the lifting mechanism and driven by the lifting mechanism to lift or descend relative to the base. When the second screen moves out of the first screen and the display surface of the display unit and the display surface of the first screen have the level difference, the display unit is suitable for being lifted relative to the base by the lifting mechanism to compensate the level difference.

Based on the above, the second screen of the portable electronic device with multiple screens of the present invention is movably coupled to the first screen to be received in or removed from the first screen, and the second screen can be lifted or lowered by the lifting mechanism to drive the display unit located on the lifting mechanism to be lifted or lowered relative to the base. Accordingly, when the second screen moves out of the first screen and the display surface of the display unit and the display surface of the first screen have a step difference, the display unit is suitable for being lifted relative to the base through the lifting mechanism to compensate the step difference, so that the portable electronic device with multiple screens has good operation flexibility and overall attractive degree, and a user can have better visual effect when operating the portable electronic device with multiple screens.

Reference will now be made in detail to the exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the description to refer to the same or like parts.

Fig. 1 is a schematic view of a portable electronic device in a first state according to an embodiment of the invention, and a part of the components are exploded. Fig. 2A is a schematic view of a part of components of the portable electronic device of fig. 1 at another view angle. Fig. 2B shows a partial enlarged view of fig. 2A at another view angle. Fig. 3 is an enlarged partial top view of the portable electronic device of fig. 1. Referring to fig. 1 to 3, in the present embodiment, a portable electronic device 1 with multiple screens, such as a notebook computer, includes a host 40 and multiple screens pivotally connected to the host 40, in the present embodiment, the screens include a first screen 10 (primary screen) and a pair of second screens 20 (secondary screens), wherein the second screens 20 are located on opposite sides of the first screen 10, the display surface of the first screen 10 and the display surface of the second screen 20 face in the same direction, and the second screen 20 is movably coupled to the first screen 10 to be received in the first screen 10 or to be moved out of the first screen 10, so that a user can adjust the overall size of the screens according to requirements. The number of second screens 20 is not limited herein, and in another embodiment not shown, only a single second screen may be assembled to the first screen.

In detail, as shown in fig. 2A and 2B, the first screen 10 has two guiding elements 12, and the side edge of the second screen 20 has two arc-shaped rails 22. The guide members 12 are disposed opposite to the arc-shaped rails 22 of the second screen 20, respectively, such that the guide members 12 are movably coupled to the arc-shaped rails 22 along the arc-shaped path C, thereby being capable of receiving the second screen 20 in the first screen 10 or moving out of the first screen 10.

Further, as shown in fig. 1, the structural composition of the pair of second screens 20 and the relationship thereof with respect to the first screen 10 are identical to each other, and thus the second screen 20 including the base 24, the two lifting mechanisms 26, and the display unit 28 is described with only one of the second screens 20 in the present embodiment. The lifting mechanism 26 is disposed on the base 24, and the display unit 28 is disposed on the lifting mechanism 26 to be driven by the lifting mechanism 26 to be lifted or lowered with respect to the base 24.
