The folding electronic device provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1 to 2, a folding electronic device provided in an embodiment of the present application includes: a first case 101, a second case 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 disposed on the first casing 101, and the second antenna radiator 202 is disposed on the second casing 201;
on the first casing 101, the distance between the first antenna radiator 102 and the hinge axis is smaller than the distance between the first antenna radiator 102 and the first opposite side; in the second casing 201, a distance between the second antenna radiator 202 and the hinge axis is smaller than a distance between the second antenna radiator 202 and a second opposite side, where the first opposite side is a side of the first casing 101 opposite to the hinge axis, and the second opposite side is a side of the second casing 201 opposite to the hinge axis;
when the first case 101 and the second case 201 are in the unfolded state, the first antenna radiator 102 and the second antenna radiator 202 are coupled;
when the first and second housings 101, 201 are in a folded state, the first and second antenna radiators 102, 202 are decoupled.
Specifically, as shown in fig. 1 and fig. 2, simplified schematic diagrams of a folding electronic device provided in an embodiment of the present application are shown, where the folding 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, the hinge may be a known mechanism that can be folded at any angle from 0 ° to 360 °, and the structure of the hinge is not limited in the embodiment of the present application. The first casing 101 and the second casing 201 are carriers of electronic components of the folding electronic device, and components corresponding to each functional module, such as a main board, a camera, a sensor, an antenna, and the like, are arranged on the first casing 101 and the second casing 201. Illustratively, the folding electronic device may be a folding screen electronic device, and the display screen used is fixedly mounted on the first casing 101 and the second casing 201. It is understood that the display screen forms a first display area and a second display area on the first casing 101 and the second casing 201, respectively. When this folding screen electronic equipment is the equipment of infolding formula, after folding back, first display area and second display area are relative face-to-face, can avoid receiving the scratch. When the folding screen electronic equipment is an outward folding type equipment, after being folded, the first display area and the second display area are deviated back to back, and any one of the display areas can be used for displaying pictures and texts. 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 under the control of software and a driving circuit to carry out image-text display. In practical application, the display module forming the first display area and the second display area can be two independent rigid display modules or a flexible display module.
In order to make the foldable electronic device have good communication quality when the foldable electronic device is in the folded state or the unfolded state, the schematic diagrams of fig. 1 and fig. 2 are combined. Each shell is provided with an antenna radiator to meet the requirements of different forms. The first antenna radiator 102 is fixedly installed in the inner cavity of the first housing 101, and the second antenna radiator 202 is fixedly installed in the inner cavity of the second housing 102, in a specific application, the antenna radiator may be fixed or machined in the inner cavity of the housing by means of bonding or laser machining, or may be directly embedded inside a solid material of the housing. Referring to the illustration of fig. 1, the side of the first casing 101 opposite to the hinge axis L is a first pair of sides m, and the side of the second casing 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 housing 201, the spacing n1 of the second antenna radiator 202 from the hinge axis L is smaller than the spacing n2 of the second antenna radiator 202 from the second opposite side n. It should be noted that the first antenna radiator 102 and the second antenna radiator 202 may have their geometric centers as reference points, for example, the straight radiator may take its midpoint. Thus, it can be seen that the first antenna radiator 102 and the second antenna radiator 202 are both arranged close to the hinge axis L of the two shells.
Illustratively, the first antenna radiator 102 and the second antenna radiator 202 may each be a strip of sheet metal, two strips of sheet metal may be arranged end to end, and the end of each strip of sheet metal is next to the side frame of each housing for mounting the hinge.
When the included angle between the first casing 101 and the second casing 102 is 180 degrees after the first casing 101 and the second casing 102 are unfolded, 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, and at this time, the first antenna radiator 102 and the second antenna radiator 202 work together to transmit and receive signals, so that the communication performance of the folding device in the unfolded state can be improved.
When the included angle between the first casing 101 and the second casing 102 after folding is greater than or equal to 0 ° and less than 180 °, the distance between the first Antenna radiator 102 and the second Antenna radiator 202 increases, the coupling effect weakens, and the first Antenna radiator 102 and the second Antenna radiator 202 can independently operate to transmit and receive signals in the form of PIFA (Planar Inverted-F Antenna) or IFA (Inverted-F Antenna), so as to meet the requirement of low power consumption of a single Antenna in any folded state.
Therefore, in the folding device in the embodiment of the application, the first antenna radiator and the second antenna radiator may form different working modes along with the form of the folding electronic device, so that transmission loss may be reduced, a bandwidth coverage range may be improved, and a communication quality requirement of the folding electronic device in different forms may be 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 casing 101 or the second casing 201 in a centralized manner, so as to save device cost and layout space.

Under the control of the operating system, the first phase shifter 3013 and the second phase shifter 3014 make the phase difference between the two rf signals be 0 ° or 180 °.
When the phase difference between the two radio frequency signals is 180 degrees, at this time, 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 manner, and the communication quality requirement of the folding device in the unfolding state is met.
When the phase difference between the two rf signals is 0 °, the two rf signals feed the first antenna radiator 102 and the second antenna radiator 202 in the manner of in-phase feeding, so that the two radiators can independently operate as PIFA antennas or IFA antennas to transmit and receive signals, thereby meeting the requirement of low power consumption of a single antenna in any folded 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.
