An electronic device according to an embodiment of the application is described below in conjunction with fig. 1-4.

As shown in fig. 1-4, an electronic device according to some embodiments of the present application, the electronic device comprising:

a support body 15, wherein the support body 15 is internally provided with a containing cavity.

A sliding body 5, said sliding body 5 being slidably connected to said supporting body 15.

Flexible screen 2, flexible screen 2 one end with support main part 15 fixed connection, the other end is walked around slide main part 5 sets up hold in the chamber and with slide main part 5 sliding connection.

A track support provided on the sliding body 5.

And the supporting crawler 9, one end of the supporting crawler 9 is fixedly connected with the supporting body 15, and the other end of the supporting crawler 9 bypasses the crawler support and is in sliding connection with the crawler support.

Under the condition that the sliding main body 5 slides towards one side far away from the supporting main body 15, the sliding main body 5 drives the flexible screen 2 to be unfolded, the track supporting piece drives the supporting track 9 to be unfolded with the flexible screen 2 synchronously, and the supporting track 9 is located below the flexible screen 2 and abutted to the flexible screen 2.

In this embodiment, through set up track support piece on sliding body 5, in the in-process that sliding body 5 drove flexible screen 2 and expandes, make sliding body 5 can drive track support piece synchronous motion, track support piece can drive and support track 9 and flexible screen 2 and expand in step to make support track 9 support flexible screen 2. Can effectively avoid launching flexible screen 2 rear portion structure overhead like this, it is not enough to have solved flexible screen 2's support to and the problem that can influence flexible screen 2's display effect and touch-control degree of accuracy when user touch-control flexible screen 2.

As shown in fig. 4, the support crawler 9 is shown in a state of being correspondingly unfolded in the area outside the support body 15 after the slide body 5 is moved away from the predetermined position with respect to the support body 15. In fig. 4, the flexible screen 2 is not shown in this area. The support crawler 9 abuts against the flexible screen 2 below the flexible screen 2 so that the support crawler 9 supports the flexible screen 2. The support track 9 can effectively avoid the flexible screen 2 from being overhead. The problem of the support of flexible screen not enough to and user can influence the display effect and the touch-control degree of accuracy of flexible screen when touching the flexible screen is solved.

As in fig. 1, one use state of the electronic device is illustrated. For example, the support body 15 and the sliding body 5 form a support for the flexible screen 2. One end of the flexible screen 2 is fixedly connected with the support main body 15, and the flexible screen 2 covers the surface of the support main body 15 from one side of the support main body 15 and extends to the position of the sliding main body 5. The flexible screen 2 located on the upper side of the electronic device in fig. 1 is displayed as a screen of the electronic device. In the left and right positions of fig. 1, the flexible screen 2 is a curved surface, and can be used as a curved surface part of the curved surface screen electronic device for screen display.

The flexible screen 2 extends to the sliding body 5 and then bypasses the sliding body 5. The flexible screen 2 is slidably coupled to the sliding body 5 such that the flexible screen 2 can slide along the sliding body 5 to enable the flexible screen 2 to be expanded or contracted with the movement of the sliding body 5. Therefore, the screen display area of the electronic equipment controlled by the user can be correspondingly increased or decreased.

The part of the flexible screen 2 that bypasses the sliding body 5 is located on the back of the screen display side, for example, the part of the flexible screen 2 that bypasses the sliding body 5 is located inside the electronic device and cannot be observed from the outside. The non-observable portions may not be used for display. The display is performed only by the flexible screen 2 at the upper side position of the electronic device and the curved surface areas at both sides.

For example, the electronic device has a first casing 1 and a second casing 14, and the first casing 1 and the second casing 14 are buckled together to form an outer shell of the electronic device. The first housing 1 and the second housing 14 are mutually slidable to fit the sliding between the support body 15 and the sliding body 5.

The first casing 1 and the second casing 14 constitute an enclosure, and an opening is formed on the side of the flexible screen 2 for display to expose the flexible screen 2.

In a state where the sliding body 5 is not separated from the supporting body 15, the area of the screen display does not change, and the flexible screen 2 is supported by the surface of the supporting body 15 and the surface of the sliding body 5.

When the display area of the flexible screen 2 needs to be adjusted to be larger, the sliding body 5 is slid to a side away from the supporting body 15 relative to the supporting body 15. The sliding of the sliding body 5 drives the flexible screen 2 to expand towards one side of the display area, so as to increase the area of the display area. Taking fig. 1 and 2 as an example, fig. 2 unfolds part of the flexible screen 2 with respect to fig. 1.

Alternatively, the flexible screen 2 is elastically connected to the support body 15 around one end of the sliding body 5.

In the process of unfolding the flexible screen 2, the flexible screen 2 is unfolded by sliding to the upper side along the left position of the sliding body 5. The flexible screen 2 is elastically connected to the support body 15, and the flexible screen 2 is straightened due to the elastic connection. During the unfolding process, the range of the flexible screen 2 unfolded is related to the range of the sliding body 5 sliding.

For example, when the sliding body 5 is moved away from the supporting body 15 by a predetermined width, the flexible screen 2 is unfolded at the upper side by the corresponding width.

For example, when the sliding body 5 is moved to a side close to the support body 15, the elastic connection causes the flexible screen 2 to be pulled toward the support body 15 around the side of the sliding body 5, and to be maintained in a straightened state. Therefore, the flexible screen 2 can be kept in a straightened state all the time in the process of adjusting the display area of the flexible screen 2. The elastic force provided by the elastic connection causes the flexible screen 2 to be tensioned to unfold flatly while the sliding body 5 and the supporting body 15 are held in the closest position.

The flexible screen 2 is unfolded as the sliding body 5 moves away from the support body 15. At the same time, the track support also moves with the sliding body 5. One end of the support track 9 is connected with the support body 15 and abuts against the flexible screen 2, and the track support is unfolded and positioned below the unfolded flexible screen 2 to form a support. The support crawler 9 has a support effect on the flexible screen 2, so that the unfolded part of the flexible screen 2 is effectively supported outside the support main body 15, thereby avoiding the overhead of the flexible screen 2.

For example, when the sliding body 5 and the supporting body 15 are held at the closest position, the sliding body 5 and the supporting body 15 move to a position where the screen display area is minimum, and a part of the supporting crawler 9 forms a support under the flexible screen 2. As the flexible screen 2 is unfolded, the track supports drive the support tracks 9 to unfold.

Optionally, the support track 9 is resiliently connected to the support body 15 around one end of the track support.

The support track 9 is elastically connected to the support body 15, and the support track 9 is tensioned at one side, so that the support track 9 is kept in a tensioned state, and the support track 9 can effectively support the flexible screen 2.

When the sliding body 5 slides to the side close to the support body 15, the support crawler 9 slides to the side of elastic connection, and the area for support is contracted. The support track 9 is resiliently connected to the support body 15 such that the support track 9 is straightened and the portion for supporting the flexible screen 2 is progressively reduced as the support track 9 slides towards one end of the resilient connection.

For example, there is an overhead region when the sliding body 5 and the support body 15 slide relative to each other, and the flexible screen 2 in the overhead region cannot be supported by the sliding body 5 or the support body 15. The structure of the support tracks 9 of the present application is adapted to the region where the flexible screen 2 is overhead, so that the flexible screen 2 can be fully supported.

In one embodiment, the track support comprises a first roller 6, the support track 9 passing around the first roller 6 and being slidingly connected to the first roller 6.

In this embodiment, the support track 9 needs to slide along the surface of the track support during deployment or retraction. The first roller 6 is provided and the supporting crawler belt 9 is wound around the first roller 6, the first roller 6 can be rotated, and the surface of the rotated first roller 6 can improve the sliding efficiency of the supporting crawler belt 9 during the expansion or contraction of the supporting crawler belt 9, and reduce the friction between the supporting crawler belt 9 and the surface of the track support, thereby improving the durability.

For example, the sliding body 5 is provided with a first rotating shaft 8, and the first rolling shaft 6 is sleeved on the first rotating shaft 8. When the support crawler 9 slides around the first roller 6, the first roller 6 can rotate in the sliding direction.

In one embodiment, as shown in fig. 1 to 3, the track support comprises two first rollers 6, the support track 9 sequentially passes around the two first rollers 6, and the two first rollers 6 are distributed in the thickness direction of the electronic device.

In this embodiment, two first rollers 6 form a support for the support track 9. The two first rollers 6 are distributed in the thickness direction of the electronic device, and can be distributed in a position closer to the lower side of the electronic device in fig. 1 to 2 after the support crawler 9 passes around the two first rollers 6. This enables the support crawler 9 to bypass the middle area within the electronic device, thereby avoiding the support crawler 9 interfering with the layout of the internal components.

For example, in fig. 1, the support crawler 9 extends around the two first rollers 6 toward the support body 15 side in a horizontal position. The structure of the support track 9 forming an elastic connection with the support body 15 causes the portion of the support track 9 that bypasses the two first rollers 6 to be straightened in a horizontal direction.

In one embodiment, as shown in fig. 1-2, the sliding body 5 is provided with a second roller 3, and the flexible screen 2 is wound around the second roller 3 and is slidably connected with the second roller 3.

In this embodiment, when the sliding body 5 moves relative to the supporting body 15, the second roller 3 is driven to rotate by the sliding generated by the unfolding of the flexible screen 2, so as to reduce the friction between the flexible screen 2 and the second roller 3. When the second roller 3 rotates, the flexible screen 2 moves to the side corresponding to the rotation 3. This can reduce the friction between flexible screen 2 and sliding body 5, has improved the life of flexible screen 2.

The flexible screen 2 is unfolded by the movement of the sliding body 5, so that the area of a display area is increased.

Or, make sliding body 5 drive to the side that is close to support main part 15 and remove, elastic connection's structure drives flexible screen 2 slides to holding intracavity portion, makes flexible screen 2 be located the outside size shrink to reduce the regional scope that shows flexible screen 2 of one side.
