Detailed Description

For better understanding of the technical solutions of the present application, the following detailed descriptions of the embodiments of the present application are provided with reference to the accompanying drawings.

With the appearance of the flexible screen, terminal equipment such as a mobile phone and the like can realize the bending and folding of the screen by utilizing the flexible screen, so that the flexible screen has a larger display area while the terminal equipment has a more compact volume. Accordingly, the terminal device may be a folding screen device or a bending screen device.

Fig. 1 is a schematic structural diagram of a folding screen device provided in the prior art. Fig. 2 is a schematic view of the folded screen apparatus of fig. 1 after closing. As shown in fig. 1 and fig. 2, a folding screen device 1 'provided in the embodiment of the present application includes two frames 11' and a flexible screen 12 'disposed on the frames 11'. The end parts of two adjacent frames 11 ' close to the rotating shaft assembly 13 ' can rotate around the rotating shaft of the rotating shaft assembly 13 ' between the two frames 11 ', so that the ends of the two frames 11 ' far from the rotating shaft assembly 13 ' are relatively close to or far away from each other, and the folding screen device 1 ' can correspondingly present different states such as closing or unfolding. The flexible screen 12 ' covers the surface of the frame 11 ' and can be folded or unfolded correspondingly with the position change between the adjacent frames 11 '.

Specifically, when the two frames 11 'of the folding screen device 1' are oppositely unfolded, they are arranged in parallel and coplanar with each other. Accordingly, the flexible screen 12 'covered on the surface of the frame 11' can be unfolded to form a larger display surface, and the display surface can be displayed as a single display screen. It should be noted that the number of the frame bodies 11 'of the folding screen device 1' may be two or more, and when the number of the frame bodies 11 'is two or more, each adjacent frame body 11' may rotate around the mutually parallel rotating shafts, so as to form a multi-layer folding structure, or expand to obtain a larger display area. In the present application, the folding screen device 1 'is mainly described as having two housings 11'.

As can be understood by those skilled in the art, the rotating shaft between two adjacent frames 11' may be a solid rotating shaft or a virtual rotating shaft. When the rotation axis is a virtual rotation axis, the rotation axis is not completely constituted by a solid component of the folding screen device, but is a virtual rotation line formed by shape constraint and displacement constraint of different components in the folding screen device 1' during relative movement. When moving relatively, two adjacent frames 11 'of the folding screen device 1' will rotate relatively around the virtual rotation axis.

The components inside the folding screen device 1 ', such as the main circuit board, the processor, the memory, and the camera assembly, may be fixed to the two frames 11', respectively. For example, the main circuit board, the processor, the memory and other components may be disposed inside one of the housings 11 ', and the other housing 11' may be used for carrying components such as the camera assembly and the antenna. At this time, in order to form electrical connection between components located in different frames 11 ', an electrical connection line is further provided in the folding screen device 1 ', both ends of the electrical connection line are respectively connected to electrical connection points of two adjacent different frames 11 ', so as to be connected with different components such as a main circuit board, a processor, a camera assembly or an antenna on each frame 11 ' and transmit electrical signals, and the electrical connection line itself is made of a flexible material and can be correspondingly bent or deformed along with the change of the relative position of the frames 11 '. Thus, when the folding screen device 1 'is in different states such as being closed or being unfolded, the electrical connection wire can still maintain the electrical connection between the two adjacent frames 11' by means of the bending deformation of the electrical connection wire.

In particular, the electrical connection lines may have a variety of different configurations and forms. The main circuit board of the folding screen device 1 'may be located in one of the frame bodies 11', and the main circuit board may transmit electrical signals with other components. In order to electrically connect the main circuit board and the other components located in the frame 11', the main circuit board and the other components need to be connected by using electrical connection wires. The electrical connection line may include a flexible circuit board (FPC) that may include a plurality of leads so that transmission of a plurality of different electrical signals may be achieved. In addition, the antenna and other components in the folding screen device 1' can be electrically connected to the main circuit board by a coaxial cable. Thus, in an alternative, the electrical connection may also comprise a single, separately provided cable, which may be used to enable signal transmission between two separate components. In this embodiment, a single cable may be used to transmit different signals such as coaxial signals.

In order to fold or unfold the flexible screen 12 ', the folding screen device 1 ' needs to have a large unfolding and folding angle, for example, in the folding screen device 1 ' in fig. 1, the angle formed by the two frames 11 ' of the folding screen device 1 ' can be changed from 0 ° to 180 °, and accordingly, the distance between the two ends of the electrical connection line can also be changed in a large range. In order to maintain the dynamic bending reliability of the electrical connection wire, it is necessary to firmly position the dynamic portions on both sides of the electrical connection wire. Therefore, the electrical connection line is limited by a three-point structure corresponding to the two frame bodies 11 'and the rotating shaft assembly 13'.

However, such three-point limitation inevitably causes a phenomenon that the electrical connection wire is twisted. For example, dimensional deviation of the two frames 11 ', the rotating shaft assembly 13', and mutual assembly position deviation of the three may finally cause the electrical connection line to be twisted in the complete machine state. After repeated dynamic bending and redundant extrusion of the twisted electric connection wire, the circuit of the electric connection wire is damaged and forms a short circuit, and further the whole machine fails.

Therefore, the folding screen device can guarantee the self-adjusting function of the electric connecting wire, when the position of the electric connecting wire is changed, the electric connecting wire keeps straight under the movement of the whole device, the distortion is avoided, the electric connecting wire electrically connected between the adjacent frame bodies is maintained to have high reliability, and the electric connecting wire is not prone to breaking or abrasion. The specific structure of the folding screen device will be described below.

Fig. 3 is a perspective view of a folding screen device according to an embodiment of the present application. Fig. 4 is an exploded schematic view of a folding screen device according to an embodiment of the present application. To make the internal structure of the folding screen apparatus clearer, fig. 4 schematically provides an exploded view of the folding screen apparatus, in which the shape and structure of the respective components are only schematically shown, and fig. 4 is only used to explain the positional relationship between the respective components. As shown in fig. 3 and 4, the folding screen device 1 provided by the embodiment of the present application includes two frames 11 and a rotating shaft assembly 13 hinged to the two frames 11. Wherein, the two frames 11 can rotate around the rotation axis of the rotation axis assembly 13 to be folded or unfolded. Specifically, the end of the two frames 11 connected to the rotating shaft assembly 13 serves as a hinged end, and the end of the frame 11 away from the rotating shaft assembly 13 serves as a free end. The free ends of the two frames 11 can rotate around the rotating shaft assembly 13, so that the folding screen device 1 is in an opened or closed state as a whole.

The folding screen device 1 further comprises electrical connection lines 14 for electrically connecting the main circuit board arranged within the frame 11 with other components, which electrical connection lines 14 may comprise flexible circuit boards. After the mounting, the middle portion 141 of the electrical connection line 14 is connected to the rotating shaft assembly 13, and both sides 142 of the electrical connection line 14 are connected to the two housings 11, respectively. In this way, the electrical connection wires 14 are fixed in the middle position and in both side positions, respectively.

Fig. 5 is a schematic diagram of a matching relationship between the hinge assembly 13, the frame 11 and the connecting piece 17 in a folding screen device according to an embodiment of the present application. In fig. 5, the shape and structure of each component are only schematically shown, and in order to make the structure clearer, the components such as the electrical connection line 14 in fig. 4 are hidden, and fig. 5 is only used for explaining the positional relationship among the components. With reference to fig. 4 and fig. 5 at the same time, the folding screen apparatus 1 provided in the embodiment of the present application further includes a connecting sheet 17, where the connecting sheet 17 is connected between the rotating shaft assembly 13 and the electrical connection line 14 and is fixed to the electrical connection line 14, so as to reinforce the electrical connection line 14 and improve the connection reliability of the electrical connection line 14.

Fig. 6 is a schematic diagram of the matching of the hinge assembly 13 and the connecting piece 17 in the folding screen device 1 according to the embodiment of the present application. Fig. 7 is an enlarged view of fig. 6 at a.

As shown in fig. 6 to 7, the connecting piece 17 is provided with a first positioning groove 171, the rotating shaft assembly 13 is provided with a first positioning column 131, and the first positioning groove 171 is matched with the first positioning column 131. In this embodiment, the first positioning groove 171 is provided on the connecting piece 17, and may be in the shape of a circular arc. The first positioning column 131 is provided on the rotary shaft assembly 13, and may be cylindrical. In other embodiments, the first positioning groove 171 may be disposed on the rotating shaft assembly 13, and accordingly, the first positioning column 131 is disposed on the connecting piece 17.

Wherein, connection piece 17 is fixed with electric connecting wire 14, and first locating column 131 can play the effect to connection piece 17 location with first positioning groove 171 cooperation back, and then plays the effect to electric connecting wire 14 location. Also, a set gap t is provided between the first positioning groove 171 and the first positioning post 131 to enable the electrical connection wire 14 to rotate relative to the rotation shaft assembly in a plane composed of the first direction and the second direction. In this embodiment, the first direction is a length direction X of the folding screen device, and the second direction is a width direction Y of the folding screen device. In other embodiments, the first direction may also be a width direction Y of the folding screen apparatus 1, and correspondingly, the second direction is a length direction X of the folding screen apparatus 1.

In this way, the electrical connection lines 14 can have a certain rotation space in a plane composed of the length direction X and the width direction Y of the folding screen apparatus 1. When the electrical connection line 14 is fixedly assembled with the left and right frame bodies 11 and the whole machine is bent, the electrical connection line 14 can rotate by an angle adapted to the positions of the left and right ends at the fixed position of the electrical connection line 14 at the middle part 141 by the tensioning force of the left and right sides in a straightened state, so that the distortion formed by three-point fixing of the electrical connection line 14 is self-corrected, and dynamic bending in a distorted state in the whole machine state is avoided.

The folding screen device provided by the present embodiment can be applied to any assembly sequence in which the electrical connection lines 14 have three fixed structures. Even if the electrical connection wire 14 is connected to the housing 11 in the last step, no twisting occurs. Therefore, the assembly reliability of the electric connecting wire is ensured, and the use reliability of the whole machine is also improved.

In a specific embodiment, the set gap is 0.15mm to 0.2 mm. Too large a gap may result in less accurate positioning of the electrical connection wires 14, while too small a gap may reduce the adjustment space of the electrical connection wires 14. Setting the gap between the first positioning groove 171 and the first positioning post 131 to 0.15mm to 0.2mm enables the electrical connection wire 14 to have a sufficient adjustment space while ensuring accurate positioning of the electrical connection wire 14.

In addition, between the rotating shaft assembly 13 and the connecting sheet 17, the connecting sheet 17 is provided with a second positioning groove 172, the rotating shaft assembly 13 is provided with a second positioning column 132, and the second positioning groove 172 is in contact fit with the second positioning column 132. In this embodiment, the second positioning groove 172 is disposed on the connecting piece 17, and may be circular arc. The second positioning column 132 is disposed on the rotating shaft assembly 13, and may be cylindrical. In other embodiments, the second positioning slot 172 can also be disposed on the rotating shaft assembly 13, and correspondingly, the second positioning column 132 is disposed on the connecting piece 17.

The contact fit of the second positioning groove 172 and the second positioning column 132 can play a role of 'fine positioning' of the connecting sheet 17, and the first positioning groove 171 and the first positioning column 131 have a gap t, so that the function of 'coarse positioning' of the connecting sheet 17 can be achieved, and the positioning accuracy and the adjustable effect of the electrical connection wire 14 can be considered.

As shown in fig. 7, since the inner space of the folding screen apparatus 1 is compact, in order that the connecting piece 17 does not occupy too much space, the first positioning groove 171 and/or the second positioning groove 172 may be provided as an open semicircular groove. Alternatively, the first positioning groove 171 and the second positioning groove 172 are both open semicircular grooves. Thus, the connecting piece 17 does not need to be designed to be long in the length direction X, so that the connecting piece does not occupy a large space, and convenience is brought to miniaturization of the folding screen.

Fig. 8 is another structural diagram of the first positioning groove 171 of the connecting piece 17 in the folding screen device 1 according to the embodiment of the present application. Alternatively, as shown in fig. 8, the first positioning groove 171 and/or the second positioning groove 172 may be closed circular grooves to cooperate with the first positioning column 131 and the second positioning column 132, respectively, so that the connecting plate 17 can rotate along with the electrical connection wire 14 in the plane of the first direction and the second direction, thereby adjusting the position of the electrical connection wire 14 to avoid twisting.

Referring to fig. 6, optionally, the outer diameter D2 of the second positioning post 132 is greater than the outer diameter D1 of the first positioning post 131. In a specific embodiment, the first positioning groove 171 and the second positioning groove 172 on the connecting piece 17 may be provided in a symmetrical structure, that is, the first positioning groove 171 and the second positioning groove 172 have the same shape and size, so as to simplify the manufacturing process of the connecting piece. The outer diameter D2 of the second positioning post 132 is larger than the outer diameter D1 of the first positioning post 131, so as to achieve the purpose of coarse positioning with a gap between the first positioning post 131 and the first positioning groove 171.

In addition, in the assembling process, because the two ends of the connecting piece 17 are correspondingly positioned finely and coarsely, if the connecting piece 17 is installed reversely, the direction needs to be adjusted again for assembling or the assembling is mistakenly carried out, which affects the assembling efficiency. Setting the outer diameter D2 of the second positioning post 132 to be larger than the outer diameter D1 of the first positioning post 131 can play a role in error proofing during the assembly process.

As shown in fig. 7, the connecting piece 17 corresponding to two sides of the first positioning groove 171 includes a first position-limiting portion 173 and a second position-limiting portion 174, wherein a width W1 of the first position-limiting portion 173 is smaller than a width W2 of the second position-limiting portion 174. In this embodiment, the connecting piece 17 forms an asymmetric structure corresponding to the position of the first positioning groove 171, and accordingly, the connecting piece 17 can be arranged to form a symmetric structure corresponding to the position of the second positioning groove 172, thereby further playing a role of error protection.

It is understood that the connecting piece 17 corresponding to the second positioning slot 172 can be disposed in an asymmetric structure, and can also be sized to distinguish the first positioning slot 171.

As an alternative embodiment, as shown in fig. 4, a connecting layer 19 is arranged between the connecting web 17 and the electrical connection line 14. The connecting layer 19 may be a glue layer capable of taking up the pulling force of the electrical connection wires 14 when they are fixed.

As an alternative embodiment, the connecting piece 17 may be a steel piece. Specifically, when the flexible circuit board is used as the electrical connection wire 14, the flexible circuit board is made of materials such as mylar, the structural strength is poor, and the structure such as an opening is not easy to be formed, so that the connecting sheet 17 is a steel sheet, and the steel sheet has strong mechanical strength while maintaining a small thickness, so that the flexible circuit board can be reliably fixed.

Referring to fig. 3, 4 and 9, the folding screen apparatus 1 may further include a pressing piece 15 and an elastic member 16. The elastic member 16 is disposed between the pressure piece 15 and the middle portion 141 of the electrical connection wire 14. The electrical connection line 14 is provided between the rotating shaft assembly 13 and the elastic member 16, and the pressure piece 15 may be connected to the rotating shaft assembly 13 by a fastener 18. Specifically, the pressing piece 15, the elastic member 16, the electric connection line 14, and the rotation shaft assembly 13 are distributed in this order in the thickness direction Z of the folding screen apparatus 1.

After the electric connecting wire 14 is fixed, in the thickness direction Z, the electric connecting wire 14 is pressed by the elastic component 16, so that the Z-direction limit of the electric connecting wire 14 is realized, and the Z-direction jump of the electric connecting wire 14 is avoided. When the electrical connection wire 14 rotates in a plane formed by the first direction and the second direction, a certain adjustment space can be provided in the Z direction due to the elastic action of the elastic member 16.

Fig. 10 is a structural cross-sectional view of the pressing block 15 in the folding screen device 1 according to an embodiment of the present application, and as shown in fig. 10, in a specific implementation, a limiting groove 151 is disposed on a side of the pressing block 15 facing the elastic component 16, and the elastic component 16 is accommodated in the limiting groove 151, so as to prevent the elastic component 16 from moving, and improve structural reliability of the folding screen device 1.

In addition, in this embodiment, the elastic member 16 may be made of elastic foam, spring, or rubber block, etc. with certain flexibility. The Z-direction jump of the electrical connection wire 14 can be prevented by the electrical connection wire 14 being pressed by the compressive elastic force of the elastic member 16.
