Detailed Description

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1 to 4, an electronic device 100 according to a first embodiment of the present application is a mobile terminal, which has functions of communication and photographing.

The electronic device 100 includes a main body 10, a movable assembly 20, and a cable 30 connected between the main body 10 and the movable assembly 20 for signal transmission therebetween. The movable assembly 20 is movably coupled to the main body 10, and specifically, the movable assembly 20 is selectively located inside the main body 10 (as shown in fig. 1) or moved out of the main body 10 relative to the main body 10 (as shown in fig. 3). 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, which may ensure the integrity of at least one surface (e.g., the front) of the main body 10 to provide a larger size display screen.

The movable assembly 20 can move in a sliding, ejecting, linear motor driving manner, and the like. The different movement manners can be realized by different mechanical components, for example, by providing a sliding slot between the movable component 20 and the main body 10, providing an elastic ejection mechanism in the main body 10, or providing a motor in the main body 10 to connect with the movable component 20, which can realize the movable connection of the movable component 20 with the main body 10 in any other conceivable manner provided by the prior art, and will not be described in detail herein.

Referring to fig. 2, the cable 30 has a first end 31 and a second end 32, the first end 31 is connected to the electrical components of the main body 10, and the second end 32 is connected to the electrical components of the movable assembly 20. The cable 30 may be a radio frequency coaxial cable.

With continued reference to fig. 1-4, 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.

Referring to fig. 5, the main body 10 has a fixing plate 14 therein, the fixing plate 14 is mounted with a main circuit board 16, and the main circuit board 16 is provided with a signal module 161, such as a Radio Frequency (RF) module. The first end 31 of the cable 30 is connected to the signal module 161. The fixing plate 14 may be an integral part of the middle frame.

The first wire management groove 18 may be a straight groove for defining the direction of the wire 30 after being led out from the signal module 161. The linear groove may be defined by at least two stopper portions 1810. Specifically, the main circuit board 16 has a surface 160, and the surface 160 is provided with at least two limiting portions 1810, and the two limiting portions 1810 are oppositely arranged and have a distance equal to the outer diameter of the cable 30 to clamp the cable 30. The length of the limiting part 1810 may be set as required, and may extend from the signal module 161 connected to the first end 31 of the cable 30 to the guide wheel 17, or may be shorter than the distance from the signal module 161 to the guide wheel 17. Each of the position-limiting portions 1810 has an elongated strip shape, and the placement direction thereof is set according to the requirement, for example, in the embodiment, the direction of the position-limiting portion 1810 (i.e., the direction of the linear groove) forms a predetermined angle with respect to the moving direction (the vertical direction X shown in the figure) of the movable assembly 20, so as to place the longer cable 30. The preset included angle can be a small angle, and the angle range is 1-30 degrees.

In other embodiments, the number of the limiting portions 1810 may be multiple, and the limiting portions 1810 may be arranged in a staggered manner, in addition to being arranged oppositely, so that the cable 30 may form a straight line.

In the present embodiment, as shown in fig. 6, the first wire arrangement groove 18 defined by the limiting part 1810 has a first groove bottom surface 185, and the first groove bottom surface 185 is the surface 160 of the main circuit board 16. In other embodiments, the first wire management groove 18 may be formed by providing a straight hollow tube on the surface 160, in which case the groove bottom surface of the first wire management groove 18 is the inner wall of the hollow tube that is adjacent to the surface 160.

In other embodiments, the first wire-arranging groove 18 may also be configured as a curved groove according to the actual internal layout of the product. For example, the portion of the cable 30 on the surface 160 of the main circuit board 16 is bent into an S-shaped configuration, and the stopper portion 1810 correspondingly includes a plurality of stoppers arranged along the S-shaped path to match the S-shaped course of the cable.

The fixation plate 14 has a surface 140 and a surface 160 having a common orientation. Guide wheel 17 is disposed on surface 140. In other embodiments, the guide wheels 17 may also be provided at suitable locations on the main circuit board 16.

Specifically, the center of guide wheel 17 is fixed to surface 140, and guide wheel 17 itself is rotatable in a counterclockwise direction about the center; the guide wheel 17 has a rounded edge 170, the rounded edge 170 being adapted to engage the cable 30.

To further limit the direction of the cable 30, a limiting wheel 19 is disposed on the side opposite to the guide wheel 17 with respect to the cable 30, and the limiting wheel 19 can also be fixed on the fixing plate 14, because the limiting wheel 19 can further limit the cable 30 led out from the guide wheel 17, so that the part of the cable 30 wound out from the guide wheel 17 can not be pulled by external force to be separated from the guide wheel 17 during the movement of the movable assembly 20. The limiting wheel 19 is positioned between the second wire arranging groove 26 and the guide wheel 17, and the cable 30 is positioned between the guide wheel 17 and the limiting wheel 19.

The guide wheel 17 is used for turning the cable 30 which originally runs along the straight line direction defined by the first cable arranging groove 18, and the part of the cable 30 led out from the guide wheel 17 until the second cable arranging groove 26 is a redundant segment 33 which can freely move.

Due to the presence of the guide wheel 17, the cable 30 is folded one section between the first and second

cable management slots

18, 26, forming a redundant section 33 providing an extendable cable length for the in and out movement of the movable assembly 20.

Referring to fig. 1 to 4, the movable element 20 is a cube structure having at least a first surface 201, a second surface 202 and a bottom surface 203 connecting the first surface 201 and the second surface 202, the first surface 201 and the front surface 102 of the main body 10 have the same orientation, and the second surface 202 and the back surface 103 of the main body 10 have the same orientation. 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.

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

As shown in fig. 5, the movable unit 20 is provided with an extending portion 24 at a position where the bottom surface 203 meets the main body 10, and the extending portion 24 extends in a direction away from the bottom surface 203. The extension 24 may be coupled to the movable assembly 20 at a location on the bottom surface 203 near the side of the main body 10 and adapted to fit within the main body 10. In other embodiments, the extension 24 may be attached at an intermediate position of the bottom surface 203.

The extension 24 is provided with a second cable management groove 26 for defining the run of the cable 30 on the movable assembly 20. Specifically, the extension 24 has a bottom 241, and in order to accommodate longer redundant cables, the entrance 260 of the second cable management groove 26 is as close as possible to the bottom 241. The bottom 241 and the first end 31 of the cable 30 are substantially at the same level, which forces the redundant segment 33 to bend at the D position (the D position and the bottom 241 and the first end 31 are substantially at the same level) and enter the entrance 260. The extension length of the extension part 24 is basically equal to the projection length of the sum of the length of the first wire arranging groove 18 and the height of the guide wheel 17 on the extension part 24.

The second wire management groove 26 runs in the same direction as the extension direction of the extension part 24. The second wire management groove 26 may be exposed at the surface 240 of the extension portion 24, or may be located inside the extension portion 24 (forming a slot). The inner diameter of the second wire management groove 26 is the same size as the outer diameter of the cable 30 to just receive the cable 30. The inner wall of the second wire management groove 26 is smooth to match the sliding of the cable 30.

Referring to fig. 6, the second wire arranging groove 26 has a second groove bottom surface 265, and the second groove bottom surface 265 is a surface of the inside of the second wire arranging groove 26, which is attached to the surface 240 of the extending portion 24, and can be considered as a surface 242 of the extending portion 24, which is opposite to the surface 240. The second slot bottom 265 and the first slot bottom 185 are flush or coplanar to minimize or eliminate the height difference when the redundant segment 33 enters the second wire management slot 26 from the main circuit board 16, so that the movement of the redundant segment 33 is smoother.

The cable 30 is routed from the first end 31 of the connection signal module 161, first along the direction defined by the first wire arrangement groove 18, then is turned by the guide wheel 17, forms (relative to other parts) a redundant segment 33 which can move freely between the leading-out position of the guide wheel 17 and the entrance 260 of the second wire arrangement groove 26, and then enters the second wire arrangement groove 26 until the antenna radiator 22 is connected. The whole cable 30 forms an S-shaped bending curve under the combined action of the first wire arranging groove 18, the guide wheel 17 and the second wire arranging groove 26.

Since the first wire management groove 18 and the second wire management groove 26 define the direction of the cable 30, the sliding track of the redundant segment 33 between the guide wheel 17 and the second wire management groove 26 is defined, so that the whole cable 30 is ensured not to be excessively bent, knotted or even broken, and the communication quality between the main body 10 and the movable assembly 20 is ensured.

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.

Referring to fig. 7, an electronic device 200 according to a second embodiment of the present disclosure includes a main body 40, a movable assembly 50, and a cable 60, wherein the cable 60 is connected between the main body 40 and the movable assembly 50 for transmitting signals therebetween.

Substantially the same as the electronic device 100 provided in the first embodiment of the present application, the movable assembly 50 is not through the front surface 402, except that the movable assembly 50 occupies the entire end of the main body 40, and can slide or pop up integrally with respect to the lower portion of the main body 40. 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 inside the main body 40, and the detailed description is omitted here.

To sum up, the arrangement of the cable 60 between the main body 40 and the movable assembly 50 is substantially the same as that in the first embodiment, because the first wire arrangement groove, the guide wheel and the second wire arrangement groove define the direction of the cable, and at the same time, the routing track of the redundant segment between the guide wheel and the second wire arrangement groove is defined, thereby ensuring that the redundant segment is not excessively bent, knotted or even broken, and ensuring the communication quality between the main body 40 and the movable assembly 50.

Referring to fig. 8, 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, triggering the movable assembly to move relative to the main body away from the main body, and enabling the redundant segment to enter the second wire arranging groove.

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 element 20 is triggered and at least partially moves outward relative to the main body, for example, when the movable element 20 moves outward from the receiving cavity 12 in a vertical direction, the extending portion 24 is driven to move upward, the redundant segment 33 has a movement tendency of moving upward along with the movable element 20, that is, the movement tendency is the same, and the movement may be performed in the second wire arranging groove 26 and also move upward. When the movable assembly 20 moves to the farthest position with respect to the main body 10, the redundant segment 33 may be in a taut state.

Further, the control method further includes step S3, when the performance index is higher than the preset threshold, triggering the movable component to move close to the main body relative to the main body, and the redundant segment has the same movement trend as the movable component.

Specifically, when the performance index is higher than the preset value, it indicates that the movable assembly 20 is about to return to the inside of the main body 10, and at this time, the redundant segment 33 is pressed back to the S-shaped bent state, for example, moved out of the second wire management groove 26, and also returned downward. When the movable assembly 20 moves relative to the main body 10 to a position completely received by the main body 10, the redundant segment 33 is in an initial relaxed state (as shown in fig. 5).
