The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.

A hinge 10, a display module, and a mobile terminal according to an embodiment of the present invention are described below with reference to fig. 1 to 10.

As shown in fig. 2 to 9, the hinge 10 according to the embodiment of the present invention includes: a base 1, a folding assembly 2 and a supporting assembly 3. The base 1 extends in a first direction (e.g., direction a in fig. 1). The folding assembly 2 includes a lifting member 21 and two sets of rotating members 22, the two sets of rotating members 22 being arranged on both sides of the base 1 in a direction orthogonal to the first direction, respectively. For example, as shown in fig. 3, two sets of rotating members 22 are symmetrically arranged on the left and right sides of the base 1.

As shown in fig. 6 and 7, the rotating member 22 is connected to the lifting member 21, and the rotating member 22 is rotatable with respect to the base 1 to drive the lifting member 21 to move. The support assembly 3 includes a floating plate 31, the floating plate 31 is located above the base 1 and defines a mounting cavity 11, the lifting member 21 is disposed in the mounting cavity 11 and connected to the floating plate 31, and when the rotating member 22 moves from the unfolded position to the folded position, the lifting member 21 can drive the floating plate 31 to move in a direction facing away from the base 1.

According to the hinge 10 of the embodiment of the invention, when the rotating member 22 moves from the unfolded position to the folded position, the rotating member 22 can drive the lifting member 21 to move, and the lifting member 21 drives the floating plate 31 to move in a direction facing away from the base 1 so as to raise the height of the floating plate 31, so that the floating plate 31 can be fully attached to the screen 20, and the supporting effect of the floating plate 31 is improved.

As shown in fig. 2 and 9, when the rotating member 22 moves from the folded position to the unfolded position, the rotating member 22 can drive the lifting member 21 to move so as to drive the floating plate 31 to descend, so that the thickness of the installation cavity 11 is reduced, sufficient space is provided for folding the screen 20, the problem that the screen 20 interferes with other parts of the hinge 10 in the folding process is avoided, the form of the screen 20 when folded can be better supported, and the service life of the screen 20 is prolonged. Therefore, the hinge 10 according to the embodiment of the present invention has a reasonable structural design and has a good supporting effect on the screen 20.

It will be appreciated that when the hinge 10 is folded to 0 deg., the two sets of rotating members 22 are arranged opposite each other, as shown in fig. 3 and 4; when the hinge 10 is unfolded to 180 deg., the two sets of rotating members 22 are located in substantially the same horizontal plane. Alternatively, a plurality of rotating members 22 located on the same side of the base 1 may be disposed symmetrically about the base 1, so that the plurality of rotating members 22 may support the screen 20 together, and thus the hinge 10 of the embodiment of the present invention has a better supporting effect on the screen 20.

In some embodiments, as shown in fig. 4 to 7, the rotating member 22 includes a first rotating member 221, a second rotating member 222, and a link plate 223, the first rotating member 221 and the second rotating member 222 are disposed on the base 1 in a first direction, one end of the first rotating member 221 is pivotably connected to the base 1, the other end of the first rotating member 221 is pivotably connected to the link plate 223, one end of the second rotating member 222 is connected to the lifting member 21 and pivotably connected to the base 1, and the other end of the second rotating member 222 is slidably connected to the link plate 223.

It will be appreciated that, as shown in fig. 5 to 7, the rotation axes of the first rotation member 221 and the base 1, the rotation axes of the first rotation member 221 and the linkage plate 223, and the rotation axes of the second rotation member 222 and the base 1 are all in the same direction as the first direction. The sliding direction of the second rotation member 222 and the linkage plate 223 is orthogonal to the first direction. When the rotating member 22 moves from the folded position to the unfolded position, the first rotating member 221 rotates relative to the base 1 to drive the linkage plate 223 to rotate relative to the base 1, and the second rotating member 222 is in sliding fit with the linkage plate 223, so that the thickness difference compensation can be realized when the hinge 10 is folded, the screen 20 is prevented from being influenced by pulling force or extrusion, the structural design is simple, and the supporting effect on the screen 20 is good.

In some embodiments, as shown in fig. 2 to 9, the support assembly 3 further includes two support plates 32, where the two support plates 32 are respectively arranged on two opposite sides of the floating plate 31 along a direction orthogonal to the first direction, the support plates 32 are located on a side of the first rotating member 221 facing away from the linkage plate 223, and in the unfolded position, the support plates 32 and the floating plate 31 are located on the same horizontal plane to ensure the flatness of the hinge 10 in the unfolded position of 180 °.

It will be appreciated that, as shown in fig. 2 to 4, in the unfolded position, the left side wall of the floating plate 31 abuts against the side wall of one of the support plates 32, and the right side wall of the floating plate 31 abuts against the side wall of the other support plate 32, so that the upper end surface of the hinge 10 when unfolded is flat, and the frame structure of the screen 20 is not interfered, and the supporting effect on the screen 20 is better. In addition, since the first rotating member 221 and the second rotating member 222 are both positioned at the lower end of the supporting plate 32, the hinge 10 has no frame, and the space occupied by the whole machine is reduced, so that the whole structure of the hinge 10 is compact and the layout is reasonable.

In other words, as shown in fig. 2 to 4, the support assembly 3 of the hinge 10 is of a three-plate structure, when the hinge 10 is folded, the two support plates 32 in the middle of the hinge 10 move around two rotation centers, so that the screen 20 is folded into a containing space in a predetermined shape, the floating plate 31 in the middle of the two support plates 32 floats up and down in the moving process of the structure, so as to avoid the screen 20, provide a larger containing space for the screen 20, avoid interference between the screen 20 and the support plates 32 of the hinge 10 in the bending process, avoid failure of the screen 20 due to stress concentration, and provide a better supporting effect of the hinge 10 on the screen 20, and have a longer service life.

The hinge 10 according to the embodiment of the present invention has the above-mentioned structure of the first rotating member 221 and the fixing base 224, so that the effect of the first rotating member 221 rotating relative to the base 1 is better, and the structural design is simple and the processing is convenient.

For example, the fixing base 224 may be detachably connected to the base 1, or the fixing base 224 may be directly formed on the base 1.

It can be appreciated that the two second mounting portions 2212 are symmetrically arranged at two sides of the first rotating member 221 along the first direction and correspond to the two second track grooves 2231 one by one, so that stability of the first rotating member 221 when rotating relative to the linkage plate 223 can be improved, which is beneficial to prolonging the service life of the hinge 10.

The hinge 10 of the embodiment of the invention can lead the structure of the hinge 10 to be compact, the layout to be reasonable and the effect to be better during the linkage by linking the rotating part 22 and the lifting part 21.
