detailed description

In order to make the objectives, technical solutions, and advantages of the present disclosure clearer, the technical solutions of the present disclosure will be clearly and completely described below in conjunction with specific embodiments of the present disclosure and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present disclosure.

The technical solutions disclosed in each embodiment of the present disclosure will be described in detail below with reference to the accompanying drawings.

As shown in FIGS. 1 to 4, embodiments of the present disclosure disclose a terminal device, which includes a housing 100, a flexible display screen 200, and a display screen bracket 300. The housing 100 has a first surface 110 and a second surface 120 opposite to each other in its thickness direction (ie, the Z direction shown in FIG. 4), and the first surface 110 and the second surface 120 are smoothly transitioned and connected. Specifically, the The first surface 110 may be the front surface of the terminal device, the second surface 120 may be the back surface of the terminal device, and the smooth transition surface may be the connecting surface 130 between the first surface 110 and the second surface 120. Of course, the terminal device may not distinguish between the front and the back. The flexible display screen 200 may specifically include a first part 210 and a second part 220, and a third part 230 connecting the first part 210 and the second part 220. The display support 300 is slidingly fitted with the housing 100, as shown in FIG. 5, it may include a rigid part 330 and a flexible part 340 connected to each other. A part of the flexible display 200 is mounted on the rigid part 330, and the other part is mounted on the flexible part 340. . Specifically, the first part 210 and the third part 230 of the flexible display screen 200 may be installed on the flexible part 340, and the second part 220 may be installed on the rigid part 330.

The flexible display 200 has a storage state and an unfolded state. As shown in FIGS. 1 and 2, in the stored state, at least a part of the flexible portion 340 is located on the first surface, and the rigid portion 330 is located on the second surface. At this time, the first portion 210 is located on the first surface 110, the second portion 220 is located on the second surface 120, and the third portion 230 is located on the connecting surface 130. Therefore, the projection of the first portion 210 and the second portion 220 in the thickness direction of the terminal device There are overlapping parts, and the two and the third part 230 together form a U-shaped display screen structure. The user can pull the display support 300 to slide the display support 300 to drive the flexible display 200 to move and reach the unfolded state as shown in FIG. 3. At this time, at least a part of the flexible portion 340 slides to the second surface 120, and The rigid part 330 is located on the same side of the housing 100. Specifically, in this state, the first part 210 and the third part 230 may be located on the second surface 120, so that the first part 210, the second part 220 and the third part 230 of the flexible display 200 are all located on the same side of the housing 100 , The display area formed by the three is larger.

According to the above content, when the flexible display screen 200 is in the expanded state, a relatively large display area can be obtained, thereby satisfying the user's demand for a large screen. At the same time, when the flexible display screen 200 is in the storage state, the first part 210 and the second part 220 thereof are stacked on the Z axis, which occupies a small space and is convenient to carry the entire terminal device. In other words, the embodiments of the present disclosure can increase the size of the flexible display screen 200 without increasing the overall size of the terminal device. In addition, the user can decide whether to expand the flexible display 200 and the extent of the expansion of the flexible display 200 according to actual needs, and this structure can prevent the flexible display 200 from being excessively bent, thereby prolonging the service life of the flexible display 200.

In addition, when the display support 300 is used to move the flexible display 200 relative to the housing 100, it also has the following advantages: when the flexible display 200 is unfolded, the rigid part 330 of the display support 300 can support the flexible display 200 to prevent The flexible display screen 200 collapses under its own gravity to facilitate user operations and then improve the user experience; the display support 300 can protect the flexible display screen 200, prevent the flexible display screen 200 from being impacted by other objects, and prolong the service life of the terminal device; The display support 300 and the flexible display 200 are relatively independent, so that it is convenient to set a structure for slidingly fitting with the housing 100, and at the same time, the display performance of the flexible display 200 is not affected.

The above-mentioned structure of the display screen bracket 300 for slidingly fitting with the housing 100 can be arranged on the side facing away from the flexible display screen 200, but this arrangement will result in a larger thickness of the terminal device. Therefore, a bracket accommodating groove 140 may be opened on the housing 100, and the display screen bracket 300 (specifically, the rigid part 330 and the flexible part 340) is disposed in the bracket accommodating groove 140. The side wall of the bracket accommodating groove 140 is provided with a sliding groove 150, and the edge of the display screen bracket 300 is slidably arranged in the sliding groove 150. That is to say, the two opposite edges of the display support 300 along the width direction of the flexible display 200 (ie, the Y direction shown in FIG. 4) extend into the sliding groove 150, thereby achieving a sliding fit, and the housing 100 can be more reliable The positions of the display support 300 and the flexible display 200 are restricted.

The chute 150 has a first inner wall surface 151 and a second inner wall surface 152 opposite in the thickness direction of the terminal device. The second inner wall surface 152 is closer to the inside of the housing 100 than the first inner wall surface 151, and both are free from The first surface 110 extends to the second surface 120. One of the aforementioned edges of the display screen bracket 300 facing the first inner wall surface 151 is provided with a sliding convex portion 310, and the sliding convex portion 310 is slidingly engaged with the first inner wall surface 151. Compared with the sliding fit between the entire edge of the entire surface and the first inner wall surface 151, the provision of the sliding protrusion 310 can appropriately reduce the contact area between the display support 300 and the housing 100, and it will appear when the flexible display 200 is unfolded and stored. The probability of the jam phenomenon makes the deployment and storage operations of the flexible display 200 smoother.

Furthermore, the sliding protrusion 310 has an arc-shaped contact surface 311, and the arc-shaped contact surface 311 is in contact with the first inner wall surface 151. On the one hand, the arc-shaped contact surface 311 is a smooth transitional curved surface, which is not easy to scratch the first inner wall 151 when sliding relative to the first inner wall 151, so as to extend the life of the terminal device; on the other hand, even if the display bracket 300 When the edge is deformed, the arc-shaped contact surface 311 can also reliably contact the first inner wall surface 151, thereby providing guidance for the sliding of the display screen bracket 300, making the sliding process more smooth.

In order to further reduce the thickness of the terminal device, a display accommodating slot 320 can be opened on the display support 300, and the flexible display 200 is arranged in the display accommodating slot 320. Specifically, the display accommodating slot 320 is simultaneously opened in the rigid 330 and flexible part 340. At this time, the two edges of the display screen bracket 300 along the thickness direction of the terminal device can limit the position of the flexible display screen 200, and prevent the film layers of the flexible display screen 200 from being misaligned or even torn.

The above-mentioned flexible portion 340 may be made of a flexible material, or may include a plurality of connecting portions 341 movably connected together. Considering that the latter solution can not only realize the deformation of the flexible portion 340, but also provide auxiliary supporting force when necessary, Therefore, the flexible portion 340 may include a plurality of connecting portions 341 which are arranged in at least one row to form at least one row of connecting units. One end of each row of connecting units is hinged with the rigid portion 330, and each row of connecting units includes a plurality of hinged connections in turn.部341. A single connecting portion 341 may be a rigid structure, and multiple connecting portions 341 may form a flexible structure after being hinged.

The above-mentioned single connecting portion 341 may be arranged in a strip-shaped structure, and its two ends respectively extend to two opposite edges of the housing 100 along the width direction of the flexible display screen 200. At this time, the length of the single connecting portion 341 is relatively large, which brings difficulties to the processing of the terminal device. For this reason, the length of a single connecting portion 341 can be shortened, and the plurality of connecting portions 341 are arranged in multiple rows to form multiple rows of connecting units, and one end of each row of connecting units is hinged to the rigid portion 330. In one way, each row of connecting units includes a plurality of connecting parts 341 hinged in sequence. The adjacent connecting portions 341 of two adjacent rows of connecting units may be connected to each other or may not be connected. When connected to each other, part of the connecting portion 341 may be hinged. In addition, the adjacent connecting portions 341 of two adjacent rows of connecting units can be arranged in alignment, that is, the connecting portions 341 of rows and columns are neatly aligned; it can also be arranged in staggered rows, that is, the adjacent connecting portions 341 of connecting units of two adjacent rows are not. Aligned. When the staggered arrangement is adopted, when the entire flexible portion 340 moves to a position corresponding to the connecting surface 130, the adjacent connecting portions 341 in two adjacent rows are hinged alternately, which can make the relative movement amplitude of each connecting portion 341 smaller Therefore, the flexible display screen 200 cannot be squeezed by the connecting portion 341, thereby better protecting the flexible display screen 200.

Further, when the flexible portion 340 includes multiple rows of connecting units, two adjacent rows of connecting units may be hinged, and the manner of hinge may be that the adjacent connecting portions 341 of the two adjacent rows of connecting units are hinged, or may be partially adjacent The connecting portion 341 may be hinged, or all adjacent connecting portions 341 may be hinged. And the hinge shafts are perpendicular to the connecting units arranged in rows. This arrangement can connect multiple rows of connecting units into a whole, and it is not easy to pull the flexible display 200 by applying force to the flexible display 200 by some of the connecting units, thereby further extending the service life of the terminal device.

Similarly, when two adjacent rows of connecting units are hinged, the adjacent connecting portions 341 of two adjacent rows of connecting units can be arranged in alignment, that is, the connecting portions 341 of rows and columns are neatly aligned; they can also be arranged in staggered rows, that is, adjacent The adjacent connecting portions 341 of the two rows of connecting units are not aligned.

As mentioned above, when two adjacent rows of connecting units are hinged, it can be specifically achieved by hinged connection of the connecting parts 341 partially arranged in a row. However, in order to make the connection of the connecting units more reliable, the multiple connecting parts 341 arranged in a row can be hinged in sequence, that is, all the adjacent connecting parts 341 in two adjacent rows of connecting units are hinged, and the hinge axes are all arranged perpendicular to the row. Connection unit. In other words, each connecting portion 341 forms a hinged relationship in the row direction (ie, the unfolding direction of the flexible display screen 200) and the column direction (ie, the Y direction in FIG. 4), and the relative positions of the row connecting units are more secure.

In order to simplify the structure of the display screen support 300, the above-mentioned flexible part 340 and the rigid part 330 may be rotatably connected by a hinge shaft 350, which may extend along the width direction of the flexible display screen 200 from one end of the flexible display screen 200 to the other. One end.

Further, as shown in FIGS. 8 and 9, the connecting portion 341 defines a first shaft hole 341a and a second shaft hole 341b, the axes of which may be parallel to each other. As shown in FIG. 9, the rigid part 330 has a third shaft hole 331, and the hinge shaft 350 passes through the third shaft hole 331 and the first shaft hole 341a of the connecting part 341 at the same time, thereby realizing the rigid part 330 and the flexible part Hinge between 340.

As shown in FIG. 7, the adjacent connecting portions 341 of two adjacent rows of connecting units include a first connecting portion A and a third connecting portion C. The first connecting portion A and the third connecting portion C can be aligned or staggered. arrangement. When arranged in a staggered arrangement, the first connecting portion A and the second connecting portion B are arranged in the same row, and the third connecting portion C is arranged staggered with the first connecting portion A and the second connecting portion B, that is, the first connecting portion A and the second connecting portion B are arranged in a staggered manner. The gap between the connecting portions B is directly opposite to the middle position of the third connecting portion C. The first hinge shaft and the second hinge shaft can realize the hinge connection between the first connection part A, the second connection part B and the third connection part C, thereby connecting the multiple rows of connection units into a whole. Specifically, the first hinge shaft (not shown) passes through a shaft hole (not shown) of the first connecting portion A and a shaft hole (not shown) of the third connecting portion C, so that the first connecting portion A and the third connecting portion C are hinged through the first hinge axis; the second hinge axis (not shown) passes through a shaft hole (not shown) of the second connecting portion B and the other axis of the third connecting portion C Hole (not shown), so that the second connecting portion B and the third connecting portion C are hinged through the second hinge shaft. Both the first hinge axis and the second hinge axis may extend along the width direction of the flexible display screen 200, that is, the vertical direction in FIG. 7, from one end to the other end of the flexible display bracket to connect the rows of connecting units into a whole .

The terminal device disclosed in the embodiment of the present disclosure may be a smart phone, a tablet computer, an e-book reader or a wearable device. Of course, the terminal device may also be another device, which is not limited in the embodiment of the present disclosure.

The above embodiments of the present disclosure focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, here No longer.

The above are only the embodiments of the present disclosure and are not used to limit the present disclosure.
