Description

TECHNICAL FIELD

[0002] In recent years, foldable screen mobile phones have become the focus of innovation in the mobile device field, bringing users a new experience of combining large screens and portability. However, the existing products have the disadvantages of being easily damaged due to screen exposure, and the screen of the vertical small foldable screen mobile phone is not large enough. The more preferred is the horizontal large inner foldable screen mobile phone, but this type of mobile phone still has shortcomings in screen ratio and use experience. The current foldable screen mobile phone design is not good, and when folded for use like a straight phone, the screen is too wide. When holding the phone with one hand, it is difficult to reach the edge of the screen with fingers, making it difficult to type with one hand. Due to the long time of holding contact with the narrow frame of the phone, the gravity distribution of the phone is uneven, which can cause hand fatigue and the phone to slip easily. Currently, the preferred screen ratio of the unfolded foldable screen is nearly square, which does not conform to the standard display ratio of the existing software ecosystem, which leads to a large number of application programs that are not compatible, and there are black edges in video playback, and the display area is not significantly increased. For mobile phone manufacturers, adapting software to special screen ratios increases costs. In terms of usage mode, the existing foldable screen mobile phone is relatively single. In the mobile office and video scenarios, users want to switch to a laptop-like mode to improve office efficiency and full-screen video display; in the entertainment scenarios such as gaming, video recording, and reading, they expect a large-screen experience similar to a tablet.

[0003] In terms of ergonomics, existing mobile phones have the disadvantages of narrow use plane width and small display text, which seriously affect eye health. According to the ergonomic technical requirements: the standard distance between humans and reading materials is about 33 cm, and the width of reading materials should be 15-21 cm according to the specifications of student textbooks, but existing products cannot meet these needs well.

[0051] As shown in Figure 1, Figure 2 and Figure 3 As shown, this is the phone mode. The first screen back panel and the second screen are folded onto the first screen and the front plane. The pop-up mechanism and the third screen are rolled up and attached to the right arc surface. The second screen back panel and the fourth screen are stacked on the rear plane. There is a small screen under the first screen back panel. The camera lens is located on the rear plane of the phone case. The phone is in the shape of a long column, with a width of 5.9 cm, a thickness of 1.8 cm, and a height of 22.4 cm.

[0052] How to use: Hold the phone directly and use the small screen to make calls, send messages, and perform other basic phone functions. To use the camera, unfold part of the phone's structure to expose the camera lens for taking pictures.

[0053] Advantages of this mode: (1) Ergonomic: The phone adopts a horizontally widened and vertically rolled-up mode, which is folded into a long and thin column shape. This shape can fully contact the palm, increase the friction area, and is suitable for human hand grip. It can effectively prevent slipping and is less likely to cause hand soreness after long-term holding. (2) Screen protection: The flexible screen is hidden inside the body when the phone is in the inward rolling mode, which can reduce accidental touch and damage and extend the life of the screen. (3) Optimized heat dissipation and performance: The screen and body are separated, which increases the volume of the host and allows the heat-generating components to be placed in the speaker and microphone for air cooling, meeting the expansion and heat dissipation needs of the processor, thereby improving the phone's external functions and hardware performance. At the same time, the host can accommodate a high-capacity battery, which improves the battery life and solves the problem of resistance loss in the connection of multiple batteries, effectively preventing the safety hazard of short circuits in thin battery electrodes. (4) Camera lens protection: When the phone is folded, the camera lens is protected, and no additional phone case or bag is needed, making it more convenient to use.

[0054] like Figure 4 and Figure 5 As shown, this is the tablet mode, with the rollable screen fully unfolded. The entire unit consists of the main body and the rollable screen, with the phone case providing stable support for the main body. The rollable screen extends from the front plane of the phone case, through the first screen back panel and the pop-up mechanism to the second screen back panel, where a flexible screen is mounted to form a large-sized flat screen.

[0055] How to use: Users can hold the phone with both hands on either side and operate it like a tablet. For example, when playing games, hold the phone horizontally on the screen to get a better, unobstructed view. This mode offers the best photography experience, capturing more content on the large screen. When reading, hold the phone vertically to simulate the reading angle of a book. It can also be placed on a flat surface such as a table for traditional tablet operation.

[0056] The advantages of this mode are: (1) Large screen experience: It provides a large screen experience similar to a tablet, which meets the user's needs for a large screen in entertainment scenarios such as playing games, taking photos, and reading, and enhances the visual enjoyment. (2) Adaptation to software ecosystem: The screen display ratio of the tablet mode is the existing standard ratio, which is consistent with the standard display ratio of the existing software ecosystem, providing users with a good visual effect, while also reducing the adaptation cost for developers.

[0057] like Figure 6 As shown, this is the laptop mode, which uses a unique rollable structure to create a form similar to a laptop. The phone case on the main body acts as a "base," providing stable support. The front left corner of the phone case is connected to the first screen back panel via a hinge, and the left side of the first screen back panel is connected to the second screen back panel via a spring-loaded mechanism. The flexible screen covers the front plane, the first screen back panel, the spring-loaded mechanism, and the second screen back panel, forming a display area similar to a laptop screen when unfolded.

[0058] Instructions for use: Unfold the phone gradually from its rolled-up state. First, open the first screen back panel, creating an angle between the second and first screen segments. Then, unfold the second screen back panel using the pop-up mechanism, extending the fourth and third screen segments. Adjust them to a suitable angle to simulate the opening and closing angle of a laptop screen. Users can place the phone on a table; the hinge bend marks the boundary between the screen display and the virtual keyboard. No external keyboard is needed for text input or other office operations, truly putting a laptop in your pocket.

[0059] The advantages of this mode are: (1) Efficient office work: It can be easily switched to a laptop-like mode to meet the needs of users in mobile office scenarios and improve office efficiency. (2) Full-screen playback of movies and TV shows without black borders. (3) This mode is suitable for standing on a desktop without a stand. It is in laptop form when the host is horizontal and in self-media form when the host and screen are folded vertically. (4) Adaptable to software ecosystem: The screen display ratio in laptop mode is the existing standard ratio, which is perfectly adapted to the existing office software ecosystem, ensuring that the software can be used normally on the screen without the need for developers to perform special adaptations, thus reducing costs.

[0060] The standard screen aspect ratios for the above modes are: mobile phones are 16:9 or 18:9; laptops are approximately 16:9; and tablets are approximately 4:3. For extended periods of use, mobile phones are typically used for video and gaming applications in laptop and tablet modes. Both of these modes have a screen width greater than 15 centimeters, conforming to the ergonomic standard of reading at a distance of one foot, effectively protecting eye health.

[0061] Finally, it should be noted that: the above embodiments are used to illustrate the technical solutions of the present application, rather than limiting them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and the specification of the present application.
