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

The first display 40 includes 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 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 first display screen 40 may be a flexible screen.

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 first display 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 first 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 first display 40, that is, they can be rotated to a state where the first portion 41 and the second portion 42 of the first display 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 first display 40 may be stacked, that is, the circuit board 50 may be disposed below the first portion 41 of the first display 40.

The rear cover 70 and the second portion 42 of the first display 40 are respectively disposed at two opposite sides of the second housing 20, for example, at two front and rear sides of the second housing 20. Thus, the second portion 42 and the rear cover 70 of the first display screen 40 can be respectively used as a front case and a rear case of the second housing 20.

In some embodiments, the rear cover 70 may also be mounted on the first housing 10. The rear cover 70 and the first portion 41 of the first display screen 40 are disposed at opposite sides of the first housing 10, respectively.

In some embodiments, the electronic device 100 also includes a second display screen 80. Wherein the second display screen 80 is mounted on the first casing 10. The second display 80 and the first portion 41 of the first display 40 are respectively disposed on two opposite sides of the first casing 10, for example, on the front and rear sides of the first casing 10. Thus, the first portion 41 of the first display 40 and the second display 80 can be respectively used as a front case and a rear case of the first housing 10.

In some embodiments, the second display screen 80 may also be mounted on the second housing 20. The second display screen 80 and the second portion 42 of the first display screen 40 are disposed on opposite sides of the second housing 20, respectively.

The second Display screen 80 may also be a Liquid Crystal Display (LCD) or an Organic Light-Emitting Diode (OLED) Display screen. The second display 80 may also be used to display images, text, etc.

For example, when the first and

second housings

10 and 20 rotate around the rotation axis 30 to a closed state, that is, rotate until the first portion 41 and the second portion 42 of the first display 40 are attached to each other, the second display 80 may serve as a display of the electronic device 100. At this time, the first display 40 may maintain the off state.

The second way of rotating the first and

second housings

10 and 20 around the rotation axis 30 is folding out. The first casing 10 and the second casing 20 both rotate along the side of the display surface departing from the first display screen 40, that is, can rotate to a state where the rear cover 70 and the second display screen 80 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.

Each of the antenna radiators 90 is configured to receive and transmit radio frequency signals. That is, each antenna radiator 90 may be used to transmit radio frequency signals, may be used to receive radio frequency signals, or may be used to both transmit and receive radio frequency signals. The plurality of antenna radiators 90 may constitute a MIMO (Multiple-Input Multiple-Output) antenna. Thus, the electronic device 100 can implement communication with a base station or other electronic devices through the antenna radiator 90.

Wherein a clearance area may be reserved under the non-display area 412 of the first portion 41 of the first display screen 40, wherein no ground plane is provided, or wherein only antenna related elements are provided. Accordingly, the plurality of antenna radiators 90 may radiate radio frequency signals to the outside through the clearance area or receive radio frequency signals from the outside. In the embodiment of the present application, when the antenna radiator 90 is disposed in the first casing 10 and the orthographic projection of the antenna radiator 90 on the first display screen 40 is located in the non-display area 412 of the first portion 41, a clearance area of the antenna radiator may be increased, so as to improve stability of the antenna radiator in receiving and transmitting the radio frequency signal.

It should be noted that, when the orthographic projection of the plurality of antenna radiators 90 on the first display screen 40 is located in the non-display area 412 of the first portion 41, it means that the plurality of antenna radiators 90 are disposed on the first portion 41 of the first display screen 40 or disposed below the first portion 41 of the first display screen 40. The antenna radiator 90 may be disposed on the front or back of the first portion 41 of the first display screen 40, or below the first portion 41 of the first display screen 40.

In some embodiments, as shown in fig. 5, the third side 41A of the first portion 41 of the first display screen 40 is disposed opposite the fourth side 41C. The opposite arrangement is that the third side 41A and the fourth side 41C are located at two opposite ends of the first portion 41 of the first display screen 40. The second side 41B is connected to the third side 41A and the fourth side 41C.

In some embodiments, as shown in fig. 6, the non-display area 412 of the first portion 41 of the first display screen 40 is provided with 8 antenna radiators 90. The 8 antenna radiators 90 are disposed at intervals from each other. The 8 antenna radiators 90 may have the same or different specifications (e.g., length, width, material, etc.).

The first area 412A and the third area 412C of the non-display area 412 are provided with 2 antenna radiators 90, and the second area 412B is provided with 4 antenna radiators 90.

In some embodiments, as shown in fig. 7, the non-display area 412 of the first portion 41 of the first display screen 40 is provided with 12 antenna radiators 90. The 12 antenna radiators 90 are disposed at intervals. The 12 antenna radiators 90 may have the same or different specifications (e.g., length, width, material, etc.). The 12 antenna radiators 90 may constitute a MIMO antenna, wherein there may be a plurality of antenna radiators for simultaneously transmitting and receiving radio frequency signals.

The first area 412A and the third area 412C of the non-display area 412 are provided with 3 antenna radiators 90, and the second area 412B is provided with 6 antenna radiators 90.

In some embodiments, as shown in fig. 8, the non-display area 412 of the first portion 41 of the first display screen 40 is provided with 16 antenna radiators 90.

The first area 412A and the third area 412C of the non-display area 412 are provided with 4 antenna radiators 90, and the second area 412B is provided with 8 antenna radiators 90.

It should be noted that, the greater the number of the antenna radiators 90 disposed on the electronic device 100, the greater the frequency bands that can be supported when the electronic device 100 receives and transmits the radio frequency signals, the greater the number of the antenna radiators that simultaneously transmit and receive the radio frequency signals on the electronic device 100, and the higher the communication stability of the electronic device 100.

In some embodiments, as shown in fig. 9, the electronic device 100 further comprises a radio frequency transceiver module 91. The radio frequency transceiver module 91 may be disposed on the circuit board 50 of the electronic device 100. The radio frequency transceiver module 91 is connected to the antenna radiator 90. The rf transceiver module 91 is configured to feed an rf signal into the antenna radiator 90.

When the rf transceiver module 91 feeds the rf signal into the antenna radiator 90, the rf transceiver module 91 has a certain transmitting power. The greater the transmission power of the rf transceiver module 91, the greater the power of the rf signal radiated to the outside by the antenna radiator 90. In addition, the rf transceiver module 91 further includes a matching circuit. The matching circuit can be used for amplifying, filtering and the like of radio frequency signals. The matching circuit may also be used to tune the radio frequency signal transmitted and received by the antenna radiator 90. The matching circuit has a certain impedance, so that the rf transceiver module 91 also has an impedance. The smaller the impedance of the rf transceiver module 91, the greater the power of the rf signal radiated to the outside by the antenna radiator 90.

In this embodiment, the impedance or the transmission power of the rf transceiver module 91 is adjustable. For example, the impedance or the transmission power of the rf transceiver module 91 may be changed according to the angle change between the first portion 41 and the second portion 42 of the first display screen 40.

In the embodiment of the present application, the electronic device 100 further includes a control circuit. The control circuit is connected to the rf transceiver module 91. Wherein the control circuit may be disposed on the circuit board 50 of the electronic device 100. The control circuit is used for controlling the impedance or the transmission power of the radio frequency transceiver module 91 according to the angle between the first portion 41 and the second portion 42 of the first display screen 40. Therefore, when the antenna radiator 90 radiates the radio frequency signal to the outside, the transmission power of the antenna radiator 90 can be in a suitable range, so that the antenna radiator 90 receives and transmits the radio frequency signal more stably, and thus the communication stability of the electronic device 100 can be improved.

In some embodiments, the electronic device 100 further comprises a distance sensor. The distance sensor is connected with the control circuit. The distance sensor is used to detect the angle between the first portion 41 and the second portion 42 of the first display screen 40. Thus, the control circuit may control the impedance or the transmission power of the rf transceiver module 91 according to the angle value detected by the distance sensor.

The distance sensor may be provided on the first portion 41 or the second portion 42 of the first display screen 40. The distance sensor may comprise an infrared sensor, an ultrasonic sensor or the like. For example, the distance sensor may be an infrared sensor. The distance sensor may include a signal transmitter and a signal receiver. The signal transmitter may be disposed on a first portion 41 of the first display screen 40 and the signal receiver may be disposed on a second portion 42 of the first display screen 40. Wherein the signal receiver receives the detection signal transmitted by the signal transmitter. The processor of the electronic device 100 may calculate the distance L1 between the signal transmitter and the signal receiver according to the detection signal received by the signal receiver.

In addition, since the signal transmitter is disposed on the first portion 41 of the first display 40 and the signal receiver is disposed on the second portion 42 of the first display 40, that is, the distance L2 between the signal transmitter and the rotation shaft 30 of the electronic device 100 is determined, and the distance L3 between the signal receiver and the rotation shaft 30 of the electronic device 100 is determined. Therefore, the electronic device 100 can calculate the angle between the first portion 41 and the second portion 42 of the first display screen 40 according to the distances L1, L2, and L3.

In some embodiments, the distance sensor may continuously detect the angle between the first portion 41 and the second portion 42 of the first display screen 40, so that the change in the angle between the first portion 41 and the second portion 42 may be acquired.

When the distance sensor detects that the angle between the first portion 41 and the second portion 42 of the first display screen 40 is increased, the second portion 42 of the first display screen 40 is gradually away from the antenna radiator 90 disposed in the first housing 10, so that the interference of the second portion 42 on the antenna radiator 90 is reduced. At this time, the control circuit controls to increase the impedance of the rf transceiver module 91 or decrease the transmission power of the rf transceiver module 91, so that the transmission power of the antenna radiator 90 when radiating the rf signal to the outside is decreased to a suitable range, thereby improving the communication stability of the electronic device 100.

When the distance sensor detects that the angle between the first portion 41 and the second portion 42 of the first display screen 40 is decreased, the second portion 42 of the first display screen 40 is gradually close to the antenna radiator 90 disposed in the first housing 10, so that the interference of the second portion 42 on the antenna radiator 90 is increased. At this time, the control circuit controls to reduce the impedance of the rf transceiver module 91 or increase the transmission power of the rf transceiver module 91, so that the transmission power of the antenna radiator 90 when radiating the rf signal to the outside is increased to a suitable range, thereby improving the communication stability of the electronic device 100.

In some embodiments, reference is continued to fig. 9. When the number of the antenna radiators 90 is multiple, the rf transceiver module 91 may include multiple signal sources 911. The plurality of signal sources 911 may be controlled by a processor of the electronic device 100. Each of the signal sources 911 is for generating a radio frequency signal. Each of the antenna radiators 90 is connected to one of the signal sources 911.

In some embodiments, a plurality of the signal sources 911 may be used to generate radio frequency signals at different frequencies. For example, one or more of The plurality of signal sources 911 may be used to generate a 4G (The 4th Generation Mobile Communication Technology, fourth Generation Mobile Communication Technology) signal. One or more of The plurality of signal sources 911 may also be used to generate a 5G (The 5th Generation Mobile Communication Technology, fifth Generation Mobile Communication Technology) signal. Accordingly, the plurality of antenna radiators 90 may be used to transmit and receive 4G signals or 5G signals.

In some embodiments, each of the antenna radiators 90 is configured to transceive radio frequency signals in a first frequency range or a second frequency range. The radio frequency signal of the first frequency range is a 4G signal, and the radio frequency signal of the second frequency range is a 5G signal. The highest frequency in the first frequency range is less than the lowest frequency in the second frequency range. That is, each of the antenna radiators 90 may be configured to transceive 4G signals and 5G signals.

In some embodiments, the first frequency range includes 615MHz (megahertz) to 4200 MHz. The second frequency range includes 4.4GHz (gigahertz) to 30 GHz.

In some embodiments, as shown in fig. 9, the first housing 10 is provided with a ground point 92. For example, the ground point 92 may be a ground point provided on the circuit board 50.
