It should be noted that, in the above embodiment, in the first direction, the larger the overlapping area of the first circuit board assembly and the second circuit board assembly, the smaller the area occupied by the circuit device in the corresponding plane of the first circuit board assembly, and correspondingly, the smaller the space occupied by the housing in the plane of the first circuit board assembly, the more convenient the electronic device is to carry and store.

Optionally, in this embodiment, the supporting device and the display device are always in a stacked and fixed state, that is, the supporting device and the display device are always kept relatively still, and always have the same form, that is, the supporting device rolls together with the display device during the process that the display device rolls along with the rotation of the rotating assembly; when the display device is in a first state, the supporting device is used for fixing the first state of the display device, so that an area of the display device meeting flattening conditions can be kept in a flattened state; when the display device is in the second state, the supporting device and the display device are accommodated in the first accommodating cavity together in the same mode.
Specifically, in one embodiment of the present application, in order to make the supporting device better maintain the state of the display device in the first state, the area of the supporting device and the area of the display device satisfy the same condition, but the present application is not limited thereto, and the present application is specifically limited thereto as the case may be. Wherein the area of the supporting device and the area of the display device meet the same conditions, including that the area of the supporting device and the area of the display device are the same, or that the area of the supporting device and the area of the display device are approximately the same.
Optionally, in an embodiment of the present application, the supporting device is a steel plate, so that the supporting device has a certain rigidity, and is fixed on the non-display side of the display device, so that when the display device is in the first state, the supporting device can be used as a supporting piece of the display device, and maintains the first state of the display device, which is simple, reliable and low in cost; specifically, in one embodiment of the present application, the supporting device is made of an ultra-thin steel plate, so that the supporting device can roll along with the display device on the basis that the supporting device can maintain the first state of the display device. Optionally, when the thickness of the display device is about 1mm, the thickness of the supporting device is 0.3mm, but the present application is not limited thereto, and the thickness is specifically determined according to circumstances.
On the basis of the above embodiments, in one embodiment of the present application, the supporting device is attached to the non-display side of the display device to achieve lamination fixation of the supporting device and the display device, but the present application is not limited thereto, and is specifically limited thereto as the case may be.
In one embodiment of the present application, the display side of the portion of the display device located in the first accommodating chamber is located on a side of the display device facing the rotating assembly, and in this embodiment, during the process that the display device rolls along with the rotation of the rotating assembly, the display surface of the display device may at least partially contact the outer surface of the rotating assembly and be easily scratched by the outer surface of the rotating assembly, so in one embodiment of the present application, in addition to any one of the above embodiments, the electronic device further includes: and the protection device covers the outer surface of the rotating assembly and is used for preventing the display surface of the display device from contacting the outer surface of the rotating assembly in the rolling process of the display device, so that the display surface of the display device is prevented from being scratched.
In another embodiment of the application, the display side of the portion of the display device located in the first receiving cavity is located on a side of the display device remote from the rotating assembly, i.e. the display side of the portion of the display device located in the first receiving cavity is located on a side of the display device facing the inner surface of the housing, and in this embodiment, during the rolling of the display device with the rotation of the rotating assembly, the display surface of the display device may at least partially contact the inner surface of the housing and be easily scratched by the inner surface of the housing, and therefore, in an alternative embodiment of the application, the electronic device further comprises: and the protection device covers the inner surface of the shell and is used for preventing the display surface of the display device from contacting the inner surface of the shell in the rolling process of the display device, so that the display surface of the display device is prevented from being scratched.
It should be noted that, in practical applications, the unfolding length of the display device may be greater than the perimeter of the rotating assembly, so as to further enable the electronic device to have a larger display area. And if the unfolding length of the display device is greater than the perimeter of the rotating assembly, when the display device is stored in the first accommodating cavity in the second state, the display device winds around the rotating assembly more than one turn, and at this time, whether the display side of the part of the display device, which is positioned in the first accommodating cavity, is positioned on the side of the display device, which faces the outer surface of the rotating assembly, or on the side of the display device, which faces the inner surface of the shell, the display surface of the display device at least partially contacts the supporting device, so that the display surface of the display device is scratched by the supporting device in the process of rolling the display device along with the rotation of the rotating assembly.
Thus, in an alternative embodiment of the application, the electronic device further comprises: and the protecting device covers one side surface of the supporting device, which is far away from the display device, and is used for preventing the display surface of the display device from contacting the supporting device in the rolling process of the display device, so that the display device is prevented from being scratched.
In summary, the electronic device provided by the embodiment of the application has a larger display area and is convenient to carry and store.
