Referring to fig. 1, fig. 1 is a schematic structural diagram of an electronic device according to an embodiment of the present disclosure. The electronic device 100 includes a first housing 10, a second housing 20, a rotation shaft 30, a display 40, a circuit board 50, and a battery 60.

Wherein, the first housing 10 and the second housing 20 are rotatably connected. The first casing 10 and the second casing 20 may include a display screen, a middle frame, a circuit board, a rear cover, and the like, which are stacked.

The first housing 10 and the second housing 20 are connected by the rotation shaft 30. That is, the first housing 10 is connected to the rotation shaft 30, and the second housing 20 is also connected to the rotation shaft 30. So that the first and

second housings

10 and 20 can rotate about the rotation shaft 30. The material of the rotating shaft 30 may include plastic or metal. The first housing 10 and the second housing 20 may be wound around the rotating shaft 30.

The first housing 10, the second housing 20 and the rotating shaft 30 may form a housing assembly.

The display 40 may be used to display information such as images, text, etc. to form a display surface of the electronic device 100. The Display screen 40 may be a Liquid Crystal Display (LCD) or an Organic Light-Emitting Diode (OLED) Display screen.

The display 40 comprises a first portion 41 and a second portion 42. The first portion 41 and the second portion 42 can both realize a display function. The first portion 41 is rotatably connected to the second portion 42. The junction of the first portion 41 and the second portion 42 is a flexible screen, i.e. the junction of the first portion 41 and the second portion 42 can be bent. Wherein, the connection can be used for displaying information or not. In some embodiments, the display screen 40 may be a flexible screen. In some embodiments, the first portion 41 and the second portion 42 may be a unitary structure.

The first portion 41 is mounted on the first housing 10, and the second portion 42 is mounted on the second housing 20. Thus, when the first and

second housings

10 and 20 rotate around the rotation shaft 30, the first and

second portions

41 and 42 of the display screen 40 can rotate around the rotation shaft 30 at the same time. When the first casing 10 and the second casing 20 rotate to the same plane, the first portion 41 and the second portion 42 of the display screen 40 are also located on the same plane, so that a larger screen display effect can be achieved.

In some embodiments, the first and

second housings

10 and 20 rotate around the rotation axis 30 in two ways. The first mode is a fold-in mode, in which the first casing 10 and the second casing 20 are both rotated along the side facing the display surface of the display screen 40, that is, they can be rotated to a state where the first portion 41 and the second portion 42 of the display screen 40 are attached to each other.

With continued reference to fig. 1, a circuit board 50 may be mounted inside the first housing 10. The circuit board 50 and the first portion 41 of the display screen 40 may be stacked, that is, the circuit board 50 may be disposed below the first portion 41 of the display screen 40.

The circuit board 50 may be a motherboard of the electronic device 100. The circuit board 50 is provided with a ground point to ground the circuit board 50. A processor is integrated on the circuit board 50. One, two or more of the functional components such as a motor, a microphone, a speaker, a receiver, an earphone interface, a universal serial bus interface (USB interface), a camera, a distance sensor, an ambient light sensor, and a gyroscope may also be integrated on the circuit board 50. Meanwhile, the display screen 40 may be electrically connected to the circuit board 50.

The battery 60 may be mounted inside the second housing 20. The battery 60 and the second portion 42 of the display screen 40 may be stacked, that is, the battery 60 may be disposed below the second portion 42 of the display screen 40.

The battery 60 may be electrically connected to the circuit board 50 to enable the battery 60 to power the electronic device 100. The circuit board 50 may be provided thereon with a power management circuit. The power management circuit is used to distribute the voltage provided by the battery 60 to the various electronic components in the electronic device 100.

Referring also to fig. 2, wherein fig. 2 is a rear view of the electronic device 100 shown in fig. 1. In some embodiments, the electronic device 100 further comprises a back cover 71. Wherein the rear cover 71 is mounted on the second housing 20. The rear cover 71 and the second portion 42 of the display screen 40 are respectively disposed on two opposite sides of the second housing 20, for example, on the front and rear sides of the second housing 20. Thus, the second portion 42 and the rear cover 71 of the display screen 40 can be used as the front shell and the rear shell of the second housing 20, respectively.

In some embodiments, the rear cover 71 may also be mounted on the first housing 10. The rear cover 71 and the first portion 41 of the display screen 40 are disposed at opposite sides of the first housing 10, respectively.

The rear cover 71 may be integrally formed. In the molding process of the rear cover 71, a rear camera hole, a fingerprint film group mounting hole, and the like may be formed on the rear cover 71.

In some embodiments, the electronic device 100 also includes a secondary display screen 72. Wherein the sub display 72 is mounted on the first housing 10. The sub-display 72 and the first portion 41 of the display 40 are respectively disposed on opposite sides of the first housing 10, for example, on the front and rear sides of the first housing 10. Thus, the first portion 41 of the display 40 and the sub-display 72 may be respectively a front case and a rear case of the first housing 10.

In some embodiments, the secondary display screen 72 may also be mounted on the second housing 20. The secondary display 72 and the second portion 42 of the display 40 are disposed on opposite sides of the second housing 20, respectively.

The sub-Display 72 may also be a Liquid Crystal Display (LCD) or an Organic Light-Emitting Diode (OLED) Display. The secondary display screen 72 may also be used to display information such as images, text, etc.

For example, when the first and

second housings

10 and 20 are rotated to the closed state around the rotation axis 30, that is, rotated until the first portion 41 and the second portion 42 of the display 40 are engaged with each other, the sub-display 72 may serve as a display of the electronic device 100. At this time, the display 40 may maintain an off state.

The second way of rotating the first and

second housings

10 and 20 around the rotation shaft 30 is to fold the housings outward. Both the first casing 10 and the second casing 20 rotate along the side of the display surface away from the display screen 40, that is, can rotate to a state where the rear cover 71 and the sub-display screen 72 are attached to each other.

In addition, in some embodiments, a middle frame structure may be disposed inside each of the first casing 10 and the second casing 20. The middle frame structure is used for providing a supporting function for the electronic components inside the first casing 10 and the second casing 20.

For example, the circuit board 50 and other electronic components in the first housing 10 may be disposed on a middle frame structure inside the first housing 10. The battery 60 and other electronic components in the second housing 20 may be disposed on a mid-frame structure inside the second housing 20.

In some embodiments, referring to fig. 3, fig. 3 is a schematic view of a second structure of an electronic device provided in the embodiments of the present application. Wherein the first housing 10 includes a first connection portion 11. The first connection portion 11 may extend outward from a side of the first housing 10. For example, the first connecting portion 11 may be formed on the first housing 10 by machining or integrally molding. The first connecting portion 11 is rotatably connected to the rotating shaft 30. For example, the first connecting portion 11 may be sleeved on the rotating shaft 30, so that the first housing 10 may rotate around the rotating shaft 30.

In some embodiments, the first connection 11 comprises a first hinge. For example, the first hinge may be formed on the first housing 10 by machining such as turning or milling. The first housing 10 is connected to the rotation shaft 30 by the first hinge.

Wherein, the first connecting portion 11 is provided with a first slide rail 12. The first slide rail 12 may be fixedly mounted on the first connecting portion 11. The first slide rail 12 is perpendicular to the rotating shaft 30. Wherein, the rotating shaft 30 can slide along the first slide rail 12. Therefore, the distance between the rotating shaft 30 and the side of the first casing 10 can be changed during the sliding process on the first slide rail 12. That is, the position of the rotational axis of the first housing 10 may be changed during the rotation of the first housing 10 about the rotational axis 30.

For example, the first slide rail 12 may be fixedly mounted on the first connecting portion 11, that is, the first slide rail 12 is fixedly connected with the first housing 10. The rotating shaft 30 can slide on the first slide rail 12 relative to the first slide rail 12, and can also rotate relative to the first slide rail 12. Thus, the rotation shaft 30 can realize both rotation with respect to the first housing 10 and sliding with respect to the first connection portion 11.

The second housing 20 includes a second connection portion 21. The second connection portion 21 may extend outward from a side of the second housing 20. The second connecting portion 21 may be formed on the second housing 20 by machining or integrally molding. The second connecting portion 21 is rotatably connected to the rotating shaft 30. For example, the second connecting portion 21 may be sleeved on the rotating shaft 30, so that the second housing 20 may rotate around the rotating shaft 30.

In some embodiments, the second connecting portion 21 includes a second hinge. For example, the second hinge may be formed on the second housing 20 by machining such as turning or milling. The second housing 20 is connected to the rotation shaft 30 by the second hinge.

The second connection portion 21 of the second housing 20 and the first connection portion 11 of the first housing 10 are both connected to the rotating shaft 30, so that the second connection portion 21 of the second housing 20 can be connected to the first connection portion 11 of the first housing 10 through the rotating shaft 30.

Wherein the second connecting portion 21 is provided with a second slide rail 22. The second slide rail 22 may be fixedly installed on the second connecting portion 21. The second slide rail 22 is perpendicular to the rotating shaft 30. Wherein, the rotating shaft 30 can slide along the second slide rail 22. Therefore, the distance between the rotating shaft 30 and the side of the second casing 20 can be changed during the sliding process on the second slide rail 22. That is, the position of the rotation axis of the second housing 20 may be changed during the rotation of the second housing 20 about the rotation axis 30.

For example, the second slide rail 22 may be fixedly mounted on the second connecting portion 21, that is, the second slide rail 22 is fixedly connected with the second housing 20. The rotating shaft 30 can slide on the second slide rail 22 relative to the second slide rail 22, and can also rotate relative to the second slide rail 22. Accordingly, the rotation shaft 30 can be rotated with respect to the second housing 20 and slid with respect to the second connection portion 21.

It should be noted that, since the first connecting portion 11 of the first casing 10 and the second connecting portion 21 of the second casing 20 are rotatably connected to the rotating shaft 30 at the same time, when the rotating shaft 30 slides, the first sliding rail 12 and the second sliding rail 22 slide at the same time.

In some embodiments, referring also to FIG. 4, FIG. 4 is a cross-sectional view of the electronic device of FIG. 3 taken along direction A-A. Wherein the first connecting portion 11 includes a first mounting hole 110. The rotating shaft 30 is installed in the first installation hole 110 to be rotatably connected with the first connection portion 11.

Wherein the first connecting portion 11 forms a first inner wall 111 at the first mounting hole 110. The first slide rail 12 is disposed on the first inner wall 111, so that the rotating shaft 30 can slide along the first slide rail 12. The rotating shaft 30 can be limited by the first sliding rail 12 and the first inner wall 111, so that the rotating shaft 30 can rotate in the first mounting hole 110 and can slide on the first sliding rail 12.

In some embodiments, referring also to FIG. 5, FIG. 5 is a cross-sectional view of the electronic device of FIG. 3 taken along direction B-B. Wherein the second connecting portion 21 includes a second mounting hole 210. The rotating shaft 30 is installed in the second installation hole 210 to be rotatably connected with the second connecting portion 21.

Wherein the second connection portion 21 forms a second inner wall 211 at the second mounting hole 210. The second slide rail 22 is disposed on the second inner wall 211, so that the rotating shaft 30 can slide along the second slide rail 22. The rotating shaft 30 can be limited by the second slide rail 22 and the second inner wall 211, so that the rotating shaft 30 can rotate in the second mounting hole 210 and can slide on the second slide rail 22.

In some embodiments, referring to fig. 6, fig. 6 is a schematic structural diagram of a third electronic device provided in the embodiments of the present application. The first housing 10 includes at least two first connecting portions 11. For example, the number of the first connection portions 11 may be 2, 3, 4, or the like. The at least two first connecting portions 11 are spaced apart. For example, one of the first connection portions 11 may be formed at a distance from each other at a side of the first housing 10.

Each of the first connecting portions 11 is provided with the first slide rail 12. Therefore, a plurality of first sliding rails 12 may be disposed on the first housing 10, so as to improve the stability of the rotating shaft 30 sliding along the first sliding rails 12.

In some embodiments, with continued reference to fig. 6, the second housing 20 includes at least two second connecting portions 21. For example, the number of the second connection portions 21 may be 2, 3, 4, or the like. The at least two second connection portions 21 are disposed at intervals. For example, the second connecting portion 21 may be formed at a distance from the side of the second housing 20.

Each of the second connecting portions 21 is provided with the second slide rail 22. Therefore, a plurality of second slide rails 22 may be disposed on the second housing 20, so as to improve the stability of the rotating shaft 30 sliding along the second slide rails 22.

Transmitting the radio frequency signal may include transmitting the radio frequency signal, receiving the radio frequency signal, and simultaneously transmitting and receiving the radio frequency signal. Thus, the electronic device 100 can transmit and receive radio frequency signals through the first antenna radiator 81 and the second antenna radiator 82 to achieve communication with a base station or other electronic devices.

In some embodiments, with continued reference to fig. 7, the first portion 41 of the display screen 40 includes a first side 411 connected to the second portion 42 and a second side 412 opposite the first side 411. The second portion 42 comprises a third side 421 connected to the first portion 41 and a fourth side 422 opposite to the third side 421.

Wherein a first distance between the first side 411 and the second side 412 is equal to a second distance between the third side 421 and the fourth side 422. That is, the width of the first portion 41 of the display screen 40 is equal to the width of the second portion 42.

Wherein an orthographic projection of the first antenna radiator 81 on the first portion 41 of the display screen 40 is located on the second side 412. That is, the first antenna radiator 81 is located on a side of the first portion 41 away from the second portion 42.

The orthographic projection of the second antenna radiator 82 on the second portion 42 of the display screen 40 is located on the fourth side 422. That is, the second antenna radiator 82 is located at a side of the second portion 42 away from the first portion 41.

Therefore, when the first and

second housings

10 and 20 are folded along the rotation axis 30, the first antenna radiator 81 may be shielded by the second portion 42 of the display 40, or may not be shielded by the second portion 42.

Referring to fig. 9, fig. 9 is a schematic diagram of a second folded state of the electronic device according to the embodiment of the present application. When the rotating shaft 30 slides to a position farther from the second side 412 of the first portion 41 and closer to the fourth side 422 of the second portion 42, after the electronic device 100 is folded, the first antenna radiator 81 is exposed, that is, the first antenna radiator 81 is not shielded by the second portion 42 of the display screen 40, and the second antenna radiator 82 is shielded by the first portion 41 of the display screen 40. In this case, the performance of the first antenna radiator 81 is less affected by the display 40, and the performance of the second antenna radiator 82 is more affected by the display 40.

In some embodiments, referring to fig. 10, fig. 10 is a schematic diagram of a fifth structure of an electronic device provided in the embodiments of the present application.

The electronic device 100 also includes a control circuit 83. The control circuit 83 may be disposed on the circuit board 50 of the electronic device 100. The control circuit 83 is connected to the first antenna radiator 81 and the second antenna radiator 82.
