Referring to fig. 1 to 4, the main body 10 has an end 101, a front surface 102, a back surface 103 opposite to the front surface 102, a first side surface 104 and a second side surface 105. The main body 10 further has a receiving cavity 12, the receiving cavity 12 is formed by the center of the end 101 being recessed toward the inside of the main body 10 and is not communicated with the front surface 102, the first side surface 104 and the second side surface 105, so as to ensure the integrity of the front surface 102; the receiving cavity 12 may or may not be through the back surface 103 (the outline of the receiving cavity 12 is visible from the back surface 103), or the outline of the receiving cavity 12 is not visible from the back surface 103, as shown in fig. 1. Since the housing cavity 12 occupies only a part of the space of the end 101, the movable assembly 20 housed therein occupies only a part of the main body 10.

In this embodiment, the end 101 is a top end when the main body 10 stands upright, and in other embodiments, may be both left and right side ends, or a bottom end opposite to the top end.

The bottom surface 203 faces the inside of the housing chamber 12. The movable assembly 20 is accommodated in the accommodating cavity 12 of the end portion 101, and the movable assembly 20 can slide out or pop out from the accommodating cavity 12 toward the end portion 101. The movable element 20 is used for disposing a front camera, an earphone, a rear camera, and the like, wherein the front camera and the earphone can be exposed on the first surface 201, and the rear camera can be exposed on the second surface 202.

In addition to being located inside the main body 10, the movable assembly 20 may also be located on the back of the main body 10, i.e. the second side 202 is coplanar with the back side 103 of the main body 10, which may ensure that at least one surface (e.g. the front) of the main body 10 has integrity to provide a larger size display.

Referring to fig. 2, 4 and 5, the cable spiral 30 and the body 10 are connected in a first position a and the movable assembly 20 is connected in a second position B. The cable spiral 30 includes a cable 301, and the cable 301 is used for signal transmission between the main body 10 and the movable assembly 20.

The cable spiral 30 is helically wound, either in a first position a or in a second position B. The cable spiral 30 has a radius that may vary, for example, the radius of the cable spiral 30 becomes smaller when the cable spiral 30 releases a portion of the cable 301 (shown in fig. 4), and the radius of the cable spiral 30 becomes larger when the cable spiral 30 recovers a portion of the cable 301 (shown in fig. 2).

The cable spiral 30 has a first end 31 and a second end 32, the first end 31 being located at the center of the entire cable spiral 30 and the second end 32 being located at the most distal end of the cable spiral 30.

In this embodiment, the first end 31 (also including one end of the cable 301) and the main body 10 are connected to a first position a, which is located at the electrical component of the main body 10; the second end 32 (also including the other end of the cable 301) and the movable assembly 20 are connected to a second location B at the electrical component of the movable assembly 20. The cable 301 used for the cable spiral 30 may be a radio frequency coaxial cable.

Referring to fig. 2, the movable assembly 20 has an antenna radiator 22 disposed therein, and the antenna radiator 22 may be disposed on the top of the movable assembly 20, and the antenna radiator 22 has a feeding point 221 (fig. 2). The second end 32 of the cable spiral 30 is connected to the feed point 221.

In the present embodiment, the main body 10 has a fixing plate 14, the fixing plate 14 is equipped with a main circuit board 16, and the main circuit board 16 is provided with a signal assembly 161 such as a Radio Frequency (RF) module. The first end 31 of the cable spiral 30 is connected to a signal assembly 161. The fixing plate 14 may be a part of a middle frame of the mobile terminal.

In the present embodiment, as shown in fig. 5, the cable spiral 30 further includes a sleeve 32 and a coil spring 34, the sleeve 32 has a hollow inner cavity 320, the coil spring 34 is located in the inner cavity 320, the coil spring 34 is used for making the sleeve 32 to be capable of being recoverably and spirally coiled, and the coil spring 34 can be filled in the whole inner cavity 320, so that the recoverability of the sleeve 32 is better. In other embodiments, the lumen 320 may also be provided with other configurations of resilient members to provide recoverability of the cannula 32.

The sleeve 32 also has an outer surface 322, and the cable 301 is wound around the outer surface 322. The winding may be a helical winding as shown, or may be any predetermined path that allows the cable 301 to be attached to the sleeve 32 and move with the sleeve 32 to release or retrieve the cable 301 relative to the center of the entire cable spiral 30.

The fixing manner of the cable 301 and the outer surface 322 includes gluing, fixing the cable 301 on the outer surface 322 by disposing a limiting structure (not shown) on the outer surface 322, or disposing a receiving groove (not shown) on the outer surface 322 for receiving and placing the cable 301, and so on, which will not be described herein again.

In summary, the electronic device 100 provided in this embodiment includes the cable screw 30, the cable screw 30 can release or recover the cable 301 repeatedly, the position of the cable 301 is relatively fixed, and meanwhile, the cable length requirement when the movable assembly 20 is far away from the main body 10 can be satisfied, thereby ensuring the communication quality inside the electronic device 100.

On the other hand, the front face 102 of the body 10 guarantees integrity due to the presence of the movable assembly 20. When the front surface 102 is a plane, after the display screen is set, the ratio of the forward projection area of the display area on the front surface 102 to the area of the front surface 102 is high, and the display screen has a high screen occupation ratio (the screen occupation ratio refers to the ratio of the screen area to the surface of the device where the display area is located, and the calculation method is that the screen occupation ratio is equal to the screen area/the surface area of the device where the display area is located), and the proportion range of the high screen occupation ratio is 85% to 100%, namely, a large screen or a full-screen is realized; for another example, when the front surface 102 is a flat surface, the outline of the display area coincides with the outline of the front surface 102.

Second embodiment

Referring to fig. 6, the electronic device 200 according to the second embodiment of the present application is substantially the same as the electronic device 100 according to the first embodiment of the present application, and the movable element 50 is not connected to the front surface, but the movable element 50 occupies the entire end of the main body 60 and can move integrally with respect to the rest of the main body 60. The sliding or ejecting structure of the movable assembly 50 can be realized by arranging a support rod, a sliding chute, a motor structure and the like in the main body 60, and the detailed description is omitted.

In summary, the electronic device 200 provided in this embodiment includes the first receiving groove, and the first receiving groove defines the direction of the cable inside the main body, and also defines the sliding track of the redundant segment from the outside of the first receiving groove to the main body connection position, so as to ensure that the entire cable is not excessively bent, knotted or even broken, and ensure the communication quality inside the electronic device 200.

Third embodiment

Referring to fig. 7, a method for controlling an

electronic device

100 or 200 according to a third embodiment of the present application includes the following steps:

and S1, detecting the performance index of the antenna radiator.

And S2, when the performance index is lower than the preset threshold value, the movable assembly is triggered to move relative to the main body and away from the main body, and the cable spiral releases a part of the cable.

Specifically, when the performance index of the antenna radiator 22 located on the movable assembly 20 changes, for example, when the performance index is lower than a preset value, it indicates that the movable assembly 20 is moving out of the main body 10. Herein, performance metrics include, but are not limited to, standing wave ratio, radiation efficiency, reflected power, return loss, and the like.

When the movable assembly 20 is moved outwardly relative to the body after being triggered, such as when the movable assembly 20 is moved in a vertical direction outwardly from the housing 12, a portion of the cable may be released by stretching the second end 32 of the cable spiral 30.

The cable spiral 30 has a minimum radius when the movable assembly 20 moves to a most distal position relative to the main body 10.

Further, the control method further includes step S3, when the performance index is higher than the preset threshold, triggering the movable assembly to move relative to the main body to approach the main body, so as to recover a portion of the cable 301 by pressing back the cable spiral 30.

In summary, the control method provided in this embodiment implements better control on the direction of the cable by using the structure in the electronic device 100(200), so as to ensure that the cable does not excessively bend, knot or even break during the movement of the movable assembly, and ensure the communication quality inside the electronic device.
