The folding electronic device provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
Referring to fig. 1 to 2, a folding electronic device provided in an embodiment of the present application includes: a first housing 101, a second housing 201, a first antenna radiator 102 and a second antenna radiator 202;
the first casing 101 is hinged to the second casing 201, the first antenna radiator 102 is arranged on the first casing 101, and the second antenna radiator 202 is arranged on the second casing 201;
on the first housing 101, a distance between the first antenna radiator 102 and the hinge axis is smaller than a distance between the first antenna radiator 102 and a first opposite side; in the second housing 201, the distance between the second antenna radiator 202 and the hinge axis is smaller than the distance between the second antenna radiator 202 and a second opposite side, wherein the first opposite side is a side opposite to the hinge axis on the first housing 101, and the second opposite side is a side opposite to the hinge axis on the second housing 201;
the first antenna radiator 102 and the second antenna radiator 202 are coupled when the first housing 101 and the second housing 201 are in the unfolded state;
the first antenna radiator 102 and the second antenna radiator 202 are decoupled when the first housing 101 and the second housing 201 are in a folded state.
Specifically, as shown in fig. 1 and 2, there is shown a simplified schematic diagram of a folded electronic device provided in an embodiment of the present application, where the folded electronic device includes a first housing 101, a second housing 201, a first antenna radiator 102, and a second antenna radiator 202. The first casing 101 and the second casing 201 are hinged by a hinge, and the hinge may be a known mechanism capable of realizing any angle of 0 ° to 360 °, and the structure of the hinge is not limited in this embodiment of the present application. The first housing 101 and the second housing 201 are carriers of electronic components of the folding electronic device, and components corresponding to respective functional modules such as a motherboard, a camera, a sensor, an antenna, and the like are provided on the first housing 101 and the second housing 201. The folding electronic device may be, for example, a folding screen electronic device, and the display screen used is mounted and fixed on the first housing 101 and the second housing 201. It will be appreciated that the display screen forms a first display area and a second display area on the first housing 101 and the second housing 201, respectively. When the folding screen electronic equipment is an inward folding type equipment, after being folded, the first display area and the second display area face to face, so that scratching can be avoided. When the folding screen electronic equipment is outward folding equipment, after being folded, the first display area and the second display area are back to back and deviate from each other, and any one display area can be used for image-text display. When the folding screen electronic equipment is unfolded, the first display area and the second display area can be connected into an integral display area for image-text display under the control of software and a driving circuit. In practical application, the display modules forming the first display area and the second display area may be two independent rigid display modules or one flexible display module.
In combination with the illustrations of fig. 1 and 2, the foldable electronic device has good communication quality in both the folded state and the unfolded state. And each shell is provided with an antenna radiator so as to meet the requirements of different forms. The first antenna radiator 102 is installed and fixed in the inner cavity of the first shell 101, and the second antenna radiator 202 is installed and fixed in the inner cavity of the second shell 102, and in specific application, the antenna radiator can be fixed or processed in the inner cavity of the shell in a bonding or laser processing mode, or is directly embedded in the solid material of the shell. Referring to the illustration of fig. 1, the side of the first housing 101 opposite to the hinge axis L is a first pair of sides m, and the side of the second housing 201 opposite to the hinge axis L is a second pair of sides n. On the first housing 101, a distance m1 between the first antenna radiator 102 and the hinge axis L is smaller than a distance m2 between the first antenna radiator 102 and the first opposite side m. In the second case 201, a distance n1 between the second antenna radiator 202 and the hinge axis L is smaller than a distance n2 between the second antenna radiator 202 and the second opposite side n. It should be noted that, the geometric centers of the first antenna radiator 102 and the second antenna radiator 202 may be used as a reference point, for example, a straight radiator may take its center point. Thus, it can be seen that both the first antenna radiator 102 and the second antenna radiator 202 are arranged close to the hinge axis L of the two housings.
Illustratively, the first antenna radiator 102 and the second antenna radiator 202 may each be strip-shaped metal sheets, which may be arranged end-to-end with an end of each strip-shaped metal sheet next to a side frame of each housing for mounting a hinge.
When the included angle between the first casing 101 and the second casing 102 after being unfolded is 180 °, the first antenna radiator 102 and the second antenna radiator 202 are closest to each other, and can be coupled to form a dipole antenna, at this time, that is, the first antenna radiator 102 and the second antenna radiator 202 work together to receive and send signals, so that the communication performance of the folding device in an unfolded state can be improved.
When the first and second cases 101 and 102 are folded to have an included angle of 0 ° or more and less than 180 °, the first and second Antenna radiators 102 and 202 become large in distance, coupling becomes weak, and the first and second Antenna radiators 102 and 202 each independently operate to transmit and receive signals in the form of PIFAs (Planar Inverted-F antennas) or IFAs (Inverted-F antennas) to meet the requirement of low power consumption of a single Antenna in any folded state.
Therefore, in the folding device of the embodiment of the application, the first antenna radiator and the second antenna radiator can form different working modes along with the forms of the folding electronic device, so that the transmission loss can be reduced, the bandwidth coverage range is improved, and the communication quality requirements of the folding electronic device in different forms are met.

In practical applications, the first antenna radiator 102 and the second antenna radiator 202 may share the same rf circuit 301, and the rf circuit 301 may be disposed in the first housing 101 or the second housing 201 in a concentrated manner, so as to save device cost and layout space. Of course, under the condition of sufficient space, the radio frequency circuit can be connected to each radiator independently, and the radio frequency circuit can be controlled to work simultaneously or independently through the operating system.

Under control of the operating system, the first phase shifter 3013 and the second phase shifter 3014 make the phase difference of the two radio frequency signals 0 ° or 180 °.
When the phase difference of the two radio frequency signals is 180 °, the two radio frequency signals feed the first antenna radiator 102 and the second antenna radiator 202 in a differential feeding manner, so that the two radiators work together in a dipole antenna mode, and the communication quality requirement of the folding device in the unfolded state is met.
When the phase difference of the two radio frequency signals is 0 °, at this time, the two radio frequency signals feed the first antenna radiator 102 and the second antenna radiator 202 in an in-phase feeding manner, so that the two radiators can independently work to receive and send signals in the form of a PIFA antenna or an IFA antenna, so as to meet the requirement of low power consumption of the single antenna in any folding state.
Of course, instead of using the illustrated rf circuit 301 to implement differential feeding and in-phase feeding, two separate rf circuits may be used to feed the first antenna radiator 102 and the second antenna radiator 202, respectively, and it will be appreciated that in this embodiment, no power divider is required because separate rf circuit feeds are used.
