The electronic device provided by the embodiments of the present application will be described in detail below through specific embodiments and application scenarios with reference to the accompanying drawings.

The application provides an electronic device, which includes:

The antenna assembly is arranged on the first casing;

In the embodiment of the present application, the electronic device includes a first housing and a second housing, the first housing and the second housing are slidably connected, and during the relative sliding of the first housing and the second housing, the flexible display screen The size of the display area changes with the sliding of the casing, and the first casing and the second casing can realize the unfolding and collapsing of the electronic device through relative sliding. For example, the above-mentioned electronic equipment includes an electronic equipment with a scroll screen, and the unfolding and folding of the electronic equipment is realized by stretching and rolling the screen around the axis; There is no limit.

Antenna components are arranged on the first housing, and when the electronic equipment is fully or partially folded, the antenna components are completely or partially covered by the second housing, and the antenna components are shielded by the second housing, which can reduce signal transmission and reduce power consumption; When all or part of the electronic device is unfolded, all or part of the antenna assembly is exposed outside the second casing, that is, at least part of the antenna assembly is not covered by the second casing, and the electronic device can use the unshielded antenna assembly for signal transmission. In this way, when the electronic device is switched between the unfolded state and the folded state, the antenna of the electronic device can be switched between the working state and the non-working state, which can reduce power consumption and improve operation convenience.

In order to facilitate understanding of this embodiment, the structure and working principle of this embodiment will be described by taking a scroll screen electronic device as an example.

As shown in FIG. 1 , the electronic device includes a first housing 11 , a scroll screen 12 , a transmission gear 13 and a second housing 14 , and the scroll screen 12 is fixedly connected to the first housing 11 or to the second housing 14 . During the relative sliding of the first shell 11 and the second shell 14, the scroll screen 12 is pulled out or rolled up around the axis, thereby realizing the unfolding and folding of the electronic device, and the transmission gear can provide power for the opening and contraction of the scroll screen. The first casing and the second casing can be provided with casing antennas, and a ring of metal can be provided on the periphery of the casing to perform signal transmission.

Among them, the setting of the shell antenna can be referred to in Figure 2. Four antennas are set on the periphery of the electronic device, which are the 11# antenna with the number 100, the 21# antenna with the number 007, the 31# antenna with the number 001, and the 41# antenna with the number 005. #Antenna; there are 2 antennas inside, namely the 12# antenna numbered 009 and the 22# antenna numbered 008. In practical applications, when the scroll screen electronic equipment is in the folded state, the electronic equipment makes the 11# antenna and the 12# antenna completely fit, and the 21# antenna and the 22# antenna completely fit together. Taking the lower end of the electronic equipment as an example, the connector 006 transmits the signal output by the tuner 003 to the 11# antenna and the 12# antenna, and the signal radiates outward. When the scroll screen of the electronic equipment is unfolded, that is, when the electronic equipment is unfolded, the 11# antenna is stuck to the 12# antenna, and the 21# antenna is stuck to the 22# antenna, so that the structure will not fall off. 002 and 004 in the figure are sliding gears. The above signal transmission process is: the radio frequency signal is output from the radio frequency power amplifier to the antenna tuner (tuner) 003, the tuned signal is connected to the antenna connector 006, and the connector 006 is connected to the antenna 009, so that the radio frequency signal of the electronic device is transmitted to the antenna 100 to radiate out .

Referring to FIG. 3 and FIG. 4, FIG. 3 is a chip diagram of an antenna tuner (tuner) of an electronic device, and FIG. 4 is an application circuit diagram of the antenna tuner. The chip diagram of the antenna tuner is a multi-switch chip plus a combined peripheral matching circuit to achieve a good match between the output of the RF signal power amplifier (Power Amplifier, PA) and the antenna, so that the signal can be transmitted from the RF signal processing module (Software Defined Radio, SDR, also known as "software radio") to the tuner 003 and then to the antenna, radiating to the signal base station several kilometers away to achieve efficient transmission. The tuner configures different peripheral circuits through switches, such as externally connecting different inductance values and capacitance value configurations, to achieve good matching under the requirements of multiple frequency bands.

During the process of folding and unfolding the electronic device, the relative positions of the first casing and the second casing change. In order to make use of the existing space of the electronic device, the embodiment of the present application fully utilizes the exposed part of the first housing as a part of the antenna when the electronic device is unfolded, so as to enhance the performance of the antenna and reduce the network delay to adapt to applications with higher network requirements At the same time, the frequency band of the antenna can also be increased, so that the electronic equipment can meet the application requirements of multiple scenarios and improve the experience of using the electronic equipment.

Specifically, when the electronic device is unfolded, at least a part of the first casing is exposed outside the second casing, that is to say, there is at least a part of the first casing that is not covered by the second casing. Antennas are set up in the covered area and can transmit signals when the electronic device is unfolded. When the electronic device is folded, the antenna assembly disposed on the first casing is hidden in the second casing, and the antenna is shielded by the second casing, thereby stopping signal transmission or weakening the signal.

For example, as shown in FIG. 5 , the exposed target area 51 of the appearance part on the first casing is used as a part of the antenna, or an antenna structure is added to the target area of the appearance part. When the electronic device is unfolded, the target area 51 is exposed, enabling signal transmission; when the electronic device is folded, the target area 51 is blocked by the second casing, and signal transmission can be stopped or weakened.

Specifically, the structure of the antenna may be a structure that can be stretched, and the exposed and shielded states of the antenna are realized through the stretching of the antenna. When the electronic device is in the retracted state, the antenna is shrunk in the second casing, and thus is covered by the second casing. When the electronic device is in the unfolded state, the antenna protrudes out of the second casing.
