Referring to fig. 1 and fig. 2, an electronic device 100 provided in the embodiment of the present application may be a mobile phone or a tablet computer, and in other embodiments, the electronic device 100 may also be other structures having a display function of the flexible screen 30, which is not limited herein.

For convenience of understanding, the structure of the electronic device 100 is described below by taking a mobile phone as an example.

The electronic device 100 includes a first body 10 and a second body 20. The first body 10 and the second body 20 are capable of sliding and extending relative to each other, and the flexible screen 30 is disposed on the first body 10 and the second body 20 and capable of adjusting a display area (hereinafter referred to as a bright screen area 30a) according to the relative sliding and extending of the first body 10 and the second body 20.

It should be noted that the flexible screen 30 is used as a structural member for displaying or touch-controlling the electronic device 100, and has a display surface, where the display surface refers to an area corresponding to a maximum display screen of the flexible screen 30, or when the bright screen area 30a is at a maximum in the relative sliding and stretching processes of the first body 10 and the second body 20, the bright screen area 30a is the same as the display surface.

Since the portion of the display surface of the flexible screen 30 is accommodated inside and not exposed during the sliding and extending process of the first body 10 and the second body 20 relative to each other, the portion does not present a display picture, and based on this, the bright screen area 30a refers to the portion of the display surface exposed to the first body 10 and the second body 20. When the bright screen area 30a is then lit up or displays a screen, the display content can be fully viewed from the outside of the electronic device 100.

In this embodiment, the size of the bright screen area 30a is changed by the relative sliding and extension of the first body 10 and the second body 20. For example, if the sliding direction of the first body 10 and the second body 20 is taken as the width direction of the electronic device 100 and its components, the bright screen area 30a expands or contracts as the first body 10 and the second body 20 slide and extend with each other.

In some embodiments, as shown in fig. 1 and 2, the bright screen area 30a is displayed, i.e., lighted up, in synchronization with the sliding of the first body 10 and the second body 20 relative to each other. Specifically, since the bright screen area 30a is an area defined by a portion of the display surface exposed out of the first body 10 and the second body 20, the width of the bright screen area 30a is changed during the sliding and stretching process of the first body 10 and the second body 20, so that when the display of the bright screen area 30a is controlled to be synchronous with the sliding and stretching process of the first body 10 and the second body 20, the overall smoothness of the picture is better, visual impact can be generated, and the user experience is improved.

The electronic device 100 according to an embodiment of the present invention adopts the following technical solution, so that the display of the bright screen area 30a can be synchronized with the sliding, stretching and retracting movement of the first body 10 and the second body 20, and the display image is harmonious and soft.

As shown in fig. 3 and 4, the electronic device 100 includes a composite shaft structure 40, and the composite shaft structure 40 includes a rotating shaft 41, and the rotating shaft 41 is rotatably connected to a side of the second body 20 opposite to the extending direction of the first body 10. The rotating shaft 41 is used for rolling up the flexible screen 30, specifically, in the process of relative sliding between the first body 10 and the second body 20, the rotating shaft 41 rolls up the flexible screen 30 to different degrees, so as to adjust the picture amplitude that the flexible screen 30 can show, that is, the display surface is exposed to the bright screen area 30a defined by the first body 10 and the second body 20.

It should be noted that, the rotating shaft 41 not only adopts the manner of rolling the flexible screen 30 to adapt to the adjustment requirement of the bright screen area 30a, but also can adopt other manners, for example, as shown in fig. 5 and fig. 6, the rotating shaft 41 is in rolling contact with the flexible screen 30, so that both ends of the flexible screen 30 are respectively bent relative to the rotating shaft 41, and thus, when the first body 10 and the second body 20 move relative to each other and the flexible screen 30 shows bright screen areas 30a with different formats, the rotating shaft 41 correspondingly rolls and abuts on different positions of the flexible screen 30 to constantly keep the bright screen area 30a of the flexible screen 30 in the diastolic state, so as to meet the requirement that the bright screen area 30a smoothly displays the picture.

As shown in fig. 5, one end of the flexible screen 30 is fixedly connected to the first body 10, and the other end of the flexible screen bypasses the rotating shaft 41 and can move relative to the second body 20 along with the relative movement between the first body 10 and the second body 20.

As shown in fig. 6 to 8, in the composite shaft structure 40, the rotating shaft 41 has a shaft cavity 41a, and the battery 42 is disposed in the shaft cavity 41a, so that the battery 42 can be disposed in the shaft cavity 41a to improve the cruising performance of the electronic device 100 while keeping the electronic device 100 compact as a whole. Specifically, in the embodiment, the composite shaft structure 40 includes the elastic connector 43, and the elastic connector 43 is electrically connected to the circuit board 101 of the electronic device 100 and elastically and electrically contacts the battery 42. Since the elastic connector 43 is in electrical contact with the battery 42 elastically, even if the bright screen area 30a of the flexible screen 30 is widened or narrowed by the relative movement of the first body 10 and the second body 20, the rotation shaft 41 moves relative to the second body 20, and the electrical contact between the elastic connector 43 and the battery 42 can be maintained.

With this configuration, the cruising performance of the electronic apparatus 100 can be effectively improved. Taking a cylindrical lithium ion battery of SP70300 as an example, the rated capacity: 85mAh, the length of a single section is less than 30mm, and the length of a connected 6 sections is about 180mm, so that when the rotating shaft 41 of the electronic device 100 meets the length condition, 6 sections of batteries 42 can be arranged, and thus, capacity improvement of 85mAh × 6-510 mAh can be brought to the electronic device 100. For a general electronic device 100, the capacity of the main battery 50 is 3500mAh, and at this time, the endurance is improved by 14.57% by the structural arrangement of the present application, and for the electronic device 100 in which the capacity of the main battery 50 is 4000mAh, the endurance is improved by 14.57% by the structural arrangement of the present application.

A plurality of cells 42 may be disposed in the axial cavity 41a, and the plurality of cells 42 are sequentially arranged along the axial cavity 41 a.

As shown in fig. 9 and 10, the batteries 42 may be connected in series, the batteries 42 at two ends are electrically connected to the elastic connector 43, and the elastic connector 43 may be electrically connected to the circuit board 101 of the electronic device 100 through a guide.

In other embodiments, the plurality of batteries 42 may be connected in parallel, and is not limited herein.

In other embodiments, only one battery 42 may be disposed within shaft cavity 41a, with battery 42 extending along shaft cavity 41a, thereby reducing the number of components of battery 42 while maintaining electrical energy storage capacity.

The battery 42 may be a rechargeable battery, for example, the charging voltage of the battery 42 is 3.7V, and the charging limit voltage is 4.2V, which is not limited herein.

The circuit board 101 is provided with a protection circuit and a controller, and the controller is electrically connected with the battery 42 through the protection circuit and is used for controlling the display screen to display pictures. When the first body 10 and the second body 20 move relatively, the protection circuit electrically disconnects the battery 42 from the controller, so as to prevent the electrical contact from being poor due to possible looseness of the contact position between the elastic connector 43 and the battery 42 during the movement of the first body 10 relative to the second body 20, which affects the power supply stability.

In this embodiment, when the first body 10 moves relative to the second body 20, the electronic device 100 may utilize the main battery 50 disposed therein to supply power, for example, as shown in fig. 6 and 9, the electronic device 100 includes the main battery 50, and the main battery 50 is electrically connected to the circuit board 101. In some embodiments, the circuit board 101 defines a receiving slot 101c, and a part of the main battery 50 is received in the receiving slot 101c, so as to prevent the main battery 50 and the circuit board 101 from overlapping in the thickness direction, so that the electronic device 100 can be made thinner.

In some embodiments, the electronic device 100 further includes a driver electrically connected to the controller and driving the first body 10 and the second body 20 to move relatively under the control of the controller, so as to control the expansion or contraction of the flexible screen 30.

As shown in fig. 5, the first body 10 includes a first housing 11, the first housing 11 has an accommodating space, and at least a portion of the second body 20 is accommodated in the accommodating space and can slide out of and into the accommodating space.

Further, the first housing 11 includes a middle plate 111 and a frame 112, the frame 112 is of a shape of \ 21274, the frame 112 is disposed at an edge of the middle plate 111 and encloses to form an accommodating space, the middle plate 111 is provided with a plurality of ribs 11c, the plurality of ribs 11c are arranged in parallel at intervals, the second housing 20 includes a support plate 21, the support plate 21 is used for supporting the flexible screen 30, the support plate 21 is provided with a plurality of grooves 21a, the plurality of grooves 21a are correspondingly in sliding fit with the plurality of ribs 11c, so that the first housing 10 and the second housing 20 can stably slide, and thus, when the electronic device 100 is in use, the flexible screen 30 is more smoothly expanded and contracted.

The circuit board 101 is disposed on a side of the middle plate 111 facing away from the support plate 21, so that the circuit board 101 does not interfere when the support plate 21 and the first housing 11 slide with each other.

As shown in fig. 5, the second body 20 includes a second housing 22, a plurality of first arc-shaped guide pieces 221 are protruded from an edge of the second housing 22, a plurality of second arc-shaped guide pieces 211 are protruded from an edge of the supporting plate 21, the second housing 22 and the supporting plate 21 are fixed to each other and movably located at two sides of the middle plate 111, and the plurality of first arc-shaped guide pieces 221 correspond to the plurality of second arc-shaped guide pieces 211.

As shown in fig. 6 to 8, the rotating shaft 41 is rotatably disposed between the first arc-shaped guide piece 221 and the second arc-shaped guide piece 211, so that the portion of the rotating shaft 41 wrapped by the first arc-shaped guide piece 221 and the second arc-shaped guide piece 211 does not contact with the flexible screen 30, thereby reducing the contact surface between the rotating shaft 41 and the flexible screen 30, reducing the unstable contact probability between the two, and improving the smoothness of expansion and contraction of the flexible screen 30.

Further, the rotating shaft 41 includes a main body 411 and a plurality of abutting portions 412 arranged at intervals along the axial direction of the main body 411, the radius of the main body 411 is smaller than the radius of the arc corresponding to the first arc-shaped guide piece 221, and the abutting portions 412 are located between the adjacent first arc-shaped guide pieces 221 and in rolling contact with the flexible screen 30, so that when the flexible screen 30 is expanded and contracted, the abutting portions 412 can drive the rotating shaft 41 to adaptively roll relative to the second housing 22.

The middle plate 111 divides the accommodating space into a first sub-space and a second sub-space, at least part of the supporting plate 21 is accommodated in the first sub-space, and at least part of the second housing 22 is accommodated in the second sub-space, so that the electronic device 100 is compact in overall structure, each part of the flexible screen 30 can be well supported, and the first body 10 and the second body 20 are stable in relative motion.
