The electronic device provided by the embodiment of the application is described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.
Referring to fig. 1 to 3, fig. 1 is a schematic diagram of a flexible screen of an electronic device in a folded state, fig. 2 is a schematic diagram of a flexible screen of an electronic device in an unfolded state, and fig. 3 is a structural explosion diagram of an electronic device in an embodiment of the present application. An embodiment of the present application provides an electronic device comprising a flexible screen 15, a support assembly and a connection assembly 13. The support assembly includes a fixed body 111, a first moving body 112 and a second moving body 113, where the first moving body 112 and the second moving body 113 are respectively disposed on two opposite sides of the fixed body 111, and the first moving body 112 and the second moving body 113 are movably connected with the fixed body 111, so that when the fixed body 111 keeps motionless, the first moving body 112 and the second moving body 113 can move relative to the fixed body 111, and further the relative position between the first moving body 112 and the second moving body 113 can also change, alternatively, when the first moving body 112 moves relative to the fixed body 111, the second moving body 113 can be immobilized, and when the second moving body 113 moves relative to the fixed body 111, the first moving body 112 can be immobilized differently, and of course, the first moving body 112 and the second moving body 113 can also move relative to the fixed body 111 simultaneously; the flexible screen 15 is disposed on the supporting component, and the supporting component provides a supporting force, and when the first moving body 112 and/or the second moving body 113 move relative to the fixed body 111, the flexible screen 15 can be driven to be unfolded or folded.
Optionally, the first moving body 112 and the second moving body 113 are both provided with a containing space, the flexible screen 15 is disposed on the supporting component, a first portion of the flexible screen 15 is fixedly connected with the fixed body 111, a second portion of the flexible screen 15 is slidably matched with the first moving body 112, a third portion of the flexible screen 15 is slidably matched with the second moving body 113, that is, when the flexible screen 15 is in a folded state, the flexible screen 15 is partially rolled in the containing spaces of the first moving body 112 and the second moving body 113, for example, a middle area (a first portion) of the flexible screen 15 is opposite to the fixed body 111 and is supported by the fixed body 111, and two side areas (a second portion and a third portion) of the flexible screen 15 are correspondingly at least partially rolled in the containing spaces of the first moving body 112 and the second moving body 113, wherein the rolling can be from a first surface of the first moving body 112/the second moving body 113 to a second surface opposite to a first surface of the first moving body, and when the first moving body 112 and/or the second moving body 113 is in a folded state, that is driven by the flexible screen 15 and/or the second moving body or the third portion is folded or unfolded.
In some optional real-time modes, in order to realize the movement of the first moving body 112 and the second moving body 113, the electronic device may further include a driving mechanism 12, where the driving mechanism 12 is connected to the first moving body 112 and the second moving body 113, respectively, and the driving mechanism 12 may drive the first moving body 112 and the second moving body 113 to make a linear motion relative to the fixed body 111 so as to drive the flexible screen 15 to switch between a deployed state and a folded state, that is, the driving mechanism 12 may drive the first moving body 112 and the second moving body 113 to make a separation motion or a facing motion with respect to the fixed body 111, so that the first moving body 112 and the second moving body 113 may drive a portion of the flexible screen 15 supported and wound thereon to be deployed or folded on two sides of the fixed body 111; it can be appreciated that the display area of the flexible screen 15 that can be seen by the user in the unfolded state is larger than the display area that can be seen by the user in the folded state, and the corresponding portion of the flexible screen 15 that can be seen in the folded state is generally stationary; alternatively, the driving mechanism 12 may drive only either one of the first moving body 112 and the second moving body 113 to move, or drive both the first moving body 112 and the second moving body 113 to move at the same time, that is, the electronic apparatus may expand the flexible screen 15 only to one side, or may expand the flexible screen 15 to both sides at the same time.
The connecting assembly 13 includes a first bracket 132 and a flexible circuit board 131, the first bracket 132 is rotatably connected with the fixed body 111, the flexible circuit board 131 is partially wound around the first bracket 132, and two ends of the flexible circuit board 131 are provided with a first interface 1311 and a second interface 1312 which are connected with each other, wherein the first interface 1311 is connected with a first device 141 located on the first moving body 112, and the second interface 1312 is connected with a second device 142 located on the second moving body 113.
In the case that the first and second moving bodies 112 and 113 move with respect to the fixed body 111, the first bracket 132 may rotate with respect to the fixed body 111 to wind or release the flexible circuit board 131, and then the distance between the first and second devices 141 and 142 is matched with the length of the non-wound portion of the flexible circuit board 131, thereby ensuring stable connection between the first and second devices 141 and 142.
Since the first device 141 is connected to the first moving body 112 and is movable with the movement of the first moving body 112, and the second device 142 is connected to the second moving body 113 and is movable with the movement of the second moving body 113, the distance between the first device 141 and the second device 142 will also vary during the movement of the first moving body 112, the second moving body 113 relative to the fixed body 111, and the length of the flexible circuit board 131 needs to be at least equal to the maximum distance between the first device 141 and the second device 142 in order to ensure the communication between the first device 141 and the second device 142.
If the solution in the prior art is adopted, that is, the length of the flexible circuit board 131 connecting the first device 141 and the second device 142 is fixed, when the distance between the first device 141 and the second device 142 is smaller than the maximum distance, the flexible circuit board 131 will be redundant, so that the overlong part of the flexible circuit board 131 is stacked inside the electronic device to cause the disorder of the internal structural space, and the flexible circuit board 131 may also be excessively bent and damaged, and be in contact with each other.
In this embodiment, when the first moving body 112 and the second moving body 113 move relative to the fixed body 111, the first bracket 132 rotates relative to the fixed body 111, for example, the first bracket 132 may perform a rotational motion about its central axis, so as to match the size of the flexible screen 15 that is unwound, so as to wind or release the flexible circuit board 131 with a corresponding length, so that the length of the unwound portion of the flexible circuit board 131 may always be kept substantially the same as or even the same as the distance between the first device 141 and the second device 142, and thus, by matching the unwinding length of the flexible circuit board with the distance between the two devices, the flexible circuit board will not have redundancy or insufficient length, so that the flexible circuit is not easily damaged during the stretching or folding of the following devices.
Optionally, the driving mechanism 12 is also connected to the first bracket 132. The first bracket 132 can be driven by the driving mechanism 12, so that the first bracket 132 can rotate around the central shaft thereof; the connection assembly 13 may also include a rotation driving mechanism connected to the first bracket 132 so as to drive the first bracket 132 to rotate around its own central axis; alternatively, in the case where the winding force required for the flexible circuit board 131 is small, the flexible circuit board 131 may be rewound by providing a mechanism such as a spring on the first bracket 132, using the elastic restoring force of the spring, and when the flexible circuit board 131 needs to be unwound, it is pulled by the first device on the first moving body 112 and/or by the second device on the second moving body 113.
In this application embodiment, utilize the coupling assembling to connect two devices that can relatively move in the electronic equipment, through the flexible circuit board in release or winding coupling assembling for flexible circuit board's expansion length and the distance phase-match between two devices, thereby flexible circuit board is being difficult to damage following device tensile or folding in-process, and, can reduce the setting restriction of device in the electronic equipment, make things convenient for the device overall arrangement, improve the overall arrangement efficiency of electronic equipment inner space.

The coil spring 133 is wound around the first bracket 132 and connected to the second bracket 134 to provide a restraining force, that is, the force of the coil spring 133 acts on the flexible circuit board 131, so that the flexible circuit board 131 is always in a compact state during winding or releasing, thereby ensuring the stability of the internal structure of the flexible screen 15 of the electronic device during the unwinding or folding.
