Referring to fig. 10, fig. 10 is a schematic diagram illustrating an internal circuit of the electronic device 100 when the sliding member 30 extends out of the device body 120.

Specifically, the radiator 82 is disposed on the slider 30 or on the surface of the slider 30, and in one embodiment, the radiator 82 is a metal sheet, but in other embodiments, the radiator 82 may also be a sheet or strip device made of a material having a radiation signal. In this embodiment, the radiator 82 is configured to radiate any one or more of a WIFI signal, an LTE signal, a millimeter wave signal, a GPS signal, a GSM signal, and a bluetooth signal. When the radiator 82 is a main set antenna, the radiator 82 is used to radiate an electromagnetic wave signal and the radiator 82 is also used to receive the electromagnetic wave signal. When the radiator 82 is a diversity antenna, the radiator 82 is used only for receiving electromagnetic wave signals and cannot radiate the electromagnetic wave signals to the outside. In one embodiment, the radiator 82 radiates the electromagnetic wave signal when the slider 30 is extended from or received in the device body 120, and in other embodiments, the radiator 82 does not radiate the electromagnetic wave signal when the slider 30 is received in the device body 120, and the radiator 82 radiates the electromagnetic wave signal when the slider 30 is extended from the device body 120. Further, when the slider 30 extends out of the device body 120, the radiator 82 protrudes out of the device body 120, the influence of the display screen 10 and other devices on the radiator 82 is small, the radiation effect of the radiator 82 is good, and when the slider 30 is accommodated in the device body 120, the radiator 82 is hidden in the device body 120, so that the portability of the electronic device 100 is improved, and meanwhile, the radiator 82 does not affect the size of the display area of the display screen 10, which is beneficial to improving the screen occupation ratio and improving the user experience.

the radiator 82 is a radiator 82 for radiating bluetooth signals, in an initial state, the slider 30 is accommodated in the device body 120, when a user manually starts a bluetooth function of the electronic device 100, or has matched another bluetooth device and is ready to perform data transmission, the driving device 50 drives the slider 30 to pop up, and the radiator 82 is located outside the device body 120, so as to improve the effect of the radiator 82 for radiating bluetooth signals and improve data transmission quality;

the radiator 82 is a radiator 82 for radiating GPS signals, and in an initial state, the slider 30 is housed in the device body 120, and when a user manually opens software such as an electronic map or navigation of the electronic device 100, the driving device 50 drives the slider 30 to pop up, and the radiator 82 is located outside the device body 120, so as to improve the effect of the radiator 82 in radiating GPS signals and improve positioning accuracy.

Referring to fig. 10, in the present embodiment, the electronic device 100 further includes a main board 42 and an auxiliary circuit board 46, the main board 42 is housed in the device body 120, the auxiliary circuit board 46 is disposed on the sliding member 30, the main board 42, the auxiliary circuit board 46 and the radiator 82 are electrically connected in sequence to provide an excitation signal for the radiator 82, and the radiator 82 generates an electromagnetic wave signal according to the excitation signal. Specifically, the antenna device 800 further includes a radio frequency circuit 84 and a matching circuit 86, the radio frequency circuit 84, the matching circuit 86, and the radiator 82 are electrically connected in sequence, so that the radio frequency circuit 84 feeds power to the radiator 82, specifically, the radio frequency circuit 84 provides an excitation source and transmits the excitation source to the matching circuit 86, and the matching circuit 86 feeds a signal to the radiator 82, so that the radiator 82 radiates an electromagnetic wave signal. In this embodiment, the matching circuit 86 is disposed on the auxiliary circuit board 46, and the matching circuit 86 is located close to the radiator 82. In one embodiment, the rf circuit 84 is disposed on the main board 42, the rf circuit 84 is electrically connected to the matching circuit 86 through the cable 410, and the rf circuit 84 is disposed on the main board 42 to reduce the number of components on the auxiliary circuit board 46, so that the size of the auxiliary circuit board 46 and the sliding member 30 is reduced, the load when the sliding member 30 slides is smaller, and the sliding member 30 slides more easily.

Referring to fig. 10, in the present embodiment, an antenna switch 88 is further disposed on the auxiliary circuit board 46, the antenna switch 88 is electrically connected between the radiator 82 and the rf circuit 84, and the antenna switch 88 is used for turning on or off a feeding path of the rf circuit 84 to the radiator 82. Specifically, the antenna switch 88 is electrically connected between the matching circuit 86 and the rf circuit 84, and the motherboard 42 may control the on/off state of the antenna switch 88, so as to control whether the radiator 82 radiates the electromagnetic wave signal. In one embodiment, when the slider 30 extends out of the device body 120, the antenna switch 88 is turned on, the rf circuit 84 feeds an antenna signal to the radiator 82, and the radiator 82 radiates an electromagnetic wave signal; when the slider 30 is accommodated in the device body 120, the antenna switch 88 is turned off, the rf circuit 84 cannot feed the antenna signal to the radiator 82, and the radiator 82 does not radiate the electromagnetic wave signal. Of course, in other embodiments, the on and off states of the antenna switch 88 may be independent of the position state of the slider 30, and for example, when the slider 30 is extended or housed in the device body 120, the antenna switch 88 is in the on state, the radiator 82 always radiates an electromagnetic wave signal, and the effect of the electromagnetic wave signal radiated by the radiator 82 differs depending on the position of the radiator 82. In other embodiments, the antenna switch 88 may also be used to adjust the feeding path of the rf circuit 84 to the radiator 82, so as to adjust the resonant frequency of the radiator 82, thereby changing the operating frequency band of the antenna device 800. In this embodiment, when the slider 30 extends out of the device body 120, the radiation environment of the radiator 82 changes, the radiation frequency of the radiator 82 shifts, that is, the radiator 82 generates frequency offset, and the antenna switch 88 adjusts the feed path of the radio frequency circuit 84 to the radiator 82, so that the actual radiation frequency band of the radiator 82 is adjusted to the target frequency band, and the radiation effect of the electromagnetic wave signal is improved. Specifically, the matching circuit 86 may include two different matching units (a first matching unit and a second matching unit), when the slider 30 extends out of the device body 120, the antenna switch 88 electrically connects the rf circuit 84 to the radiator 82 through the first matching unit, and when the slider 30 is accommodated in the device body 120, the antenna switch 88 electrically connects the rf circuit 84 to the radiator 82 through the second matching unit, so as to change the operating frequency band of the antenna apparatus 800.
