The dual-screen terminal 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 11(c), and the dual-screen terminal 100 may be a smart phone, a tablet computer, a vehicle-mounted computer, or the like.

As shown in fig. 1 to 7, a dual screen terminal 100 according to an embodiment of the present invention includes: the screen display device comprises a machine shell 1, a screen collecting component 2 and a screen 3.

The case 1 has a case front 13 and a case back 14 on both sides in the thickness direction. The reference to the front and back sides herein is only for convenience of describing the position of the screen 3 by means of both sides of the housing 1, and does not limit the front side to be the main use side of the dual-screen terminal 100, and the main use side of the dual-screen terminal 100 may be either the front side or the back side.

The cabinet 1 includes a main casing 11 and an extendable portion 12, and the extendable portion 12 is telescopically provided on the main casing 11 in an extension direction. And telescopic part 12 has a first position and a second position on main housing 11, a dimension of casing 1 in the telescopic direction when telescopic part 12 is in the first position is a first dimension d1, a dimension of casing 1 in the telescopic direction when telescopic part 12 is in the second position is a second dimension d2, and d2> d1 are satisfied. That is, by providing the extendable portion 12, the size of the housing 1 in the extending and retracting direction can be changed. For example, the telescopic direction is the width direction of the dual screen terminal 100, and the width of the housing 1 may vary between d1 and d 2. For another example, the telescopic direction is the length direction of the dual screen terminal 100, and the length of the housing 1 may vary between d1 and d 2. For reducing redundancy, the following description will be given by taking the telescopic direction as the width direction of the dual-screen terminal 100 as an example when the embodiment is described, and certainly, the scheme that the telescopic direction is the length direction of the dual-screen terminal 100 is taken in the following embodiment. When the dual-screen terminal 100 is stored, the width of the housing 1 can be reduced to d1, so that the space occupied by the dual-screen terminal 100 is small; the width of the housing 1 may be extended to d2 when the dual screen terminal 100 is in use.

As shown in fig. 5 and 6, the screen retraction assembly 2 is provided on the cabinet 1. Here, the screen accommodating unit 2 is used to accommodate a part of the screen 3, and the screen accommodating unit 2 may be provided in the housing 1 or may be provided at one end of the housing 1, for example, at one end in the width direction of the main casing 11 or the extendable portion 12.

The screen 3 may be curved, the screen 3 including: a front panel 31 on the front 13 of the housing, a back panel 32 on the back 14 of the housing, and a curved panel 33 connecting the front panel 31 and the back panel 32. At least one of the two ends of the screen 3 is disposed on the expansion part 12, so that the expansion part 12 can pull the screen 3 to be widened when extended, thereby changing the width of the screen 3. And at least one of both ends of the screen 3 is connected to the screen accommodating member 2, so that when the screen 3 is widened, the screen 3 is drawn out of the portion accommodated in the screen accommodating member 2, and when the screen 3 is narrowed, the surplus portion of the screen 3 is accommodated in the screen accommodating member 2.

To understand the connection relationship between the screen 3 and the housing 1, it is further defined that the end of the front panel 31 away from the curved panel 33 is disposed on the telescopic portion 12, so that when the telescopic portion 12 is switched from the first position to the second position (i.e. the housing 1 is narrowed and widened), the telescopic portion 12 extends away from the curved panel 33. The end of the rear panel 32 remote from the curved panel 33 may be provided on the main housing 11 or on the extendable portion 12. When the end of the back panel 32 away from the curved panel 33 is disposed on the main body 11, the width of the screen 3 changes by a width equal to the total width of the screen 3 exposed on the surface of the housing 1 when the housing 1 expands and contracts, i.e., the total width of the screen 3 exposed on the surface of the housing 1 changes by δ d when the width of the housing 1 changes by δ d. When the end of the back panel 32 away from the curved panel 33 is disposed on the expansion part 12, the total width of the screen 3 exposed to the surface of the housing 1 is changed by a width substantially twice as large as that of the housing 1 when the housing 1 expands and contracts, i.e., the total width of the screen 3 exposed to the surface of the housing 1 is changed by δ d2 times as large as that of the housing 1 when the width of the housing 1 is changed by δ d. Here, the total width of the screen 3 exposed on the surface of the housing 1 refers to the sum of the widths of the front panel 31, the rear panel 32, and the curved panel 33, and does not include the portion accommodated in the screen accommodating unit 2.

It will be understood that the designations of the front panel 31, the rear panel 32 and the curved panel 33 are made by designating the various regions of the screen 3 at different locations on the housing 1 and do not imply that the screen 3 is divided into three segments during processing. That is, the area of the screen 3 on the front 13 of the case is called a front panel 31, the area of the screen 3 on the back 14 of the case is called a back panel 32, and the bent portion of the screen 3 between the front panel 31 and the back panel 32 is called a bent panel 33. Since the areas of the front 13 and the back 14 of the housing are changed when the extendable portion 12 is located at the first position and the second position, and the extendable portion 12 extends and retracts to drive the screen 3 to extend and retract, the position of the upper portion of the screen 3 on the housing 1 is changed, and it is possible that the area belongs to the back screen 32 when the extendable portion 12 is located at the first position, but belongs to the front screen 31 when the extendable portion 12 is located at the second position.
