Description

Technical Field

[0001] The present invention relates to a hinge and a foldable flexible screen mobile terminal using the hinge.

Background Art

[0002] Regarding the shape in which the curved part bulges when the foldable flexible screen mobile terminal folds the flexible screen, certain structural measures have been taken. One measure is to provide a lifting plate in the middle, so that when the foldable flexible screen mobile terminal is folded, the lifting plate descends to avoid the lower end of the flexible screen curved part. When the foldable flexible screen mobile terminal is opened flat, the lifting plate rises to the support height to support the flexible screen in the middle. However, such a structure poses certain conditions for the thickness of the middle casing. When the user desires a relatively thin thickness for the flexible screen mobile terminal, such a structure cannot be used.

Summary of the Invention

[0003] 〈The first problem to be solved by the invention〉 Regarding the problems existing in the background art, the present invention provides new technical means that can be used in a foldable flexible screen mobile terminal, can avoid the lower end of the flexible screen curved part, and can support the flexible screen in the middle when the foldable flexible screen mobile terminal is opened flat, and at the same time reduce the conditions for the thickness of the middle casing.

[0004] 〈Technical means for realizing the first problem〉 The hinge includes a left rotating support base and a right rotating support base. The left rotating support base and the right rotating support base rotate around a first axis and a second axis respectively, the first axis and the second axis are parallel, and a synchronous opposite-direction rotation connection mechanism is connected between the left rotating support base and the right rotating support base to perform synchronous opposite-direction rotation.

[0005] It further includes a left intermediate rotation support member and a right intermediate rotation support member. The rotation axis of the left intermediate rotation support member is parallel or coincident with the first axis, and the rotation axis of the right intermediate rotation support member is parallel or coincident with the second axis.

[0006] The left rotation support base and the right rotation support base are respectively arranged at the support positions when the left intermediate rotation support member and the right intermediate rotation support member are flatly opened.

[0007] The left intermediate rotation support member and the right intermediate rotation support member are respectively connected to elastic members. When the hinge is folded, the elastic members rotate the left rotation support member and the right rotation support member downward and rotate them into the middle casing of the mobile terminal, which is characterized by this.

[0008] Furthermore, the hinge includes a first axis and a second axis. Both the left intermediate rotation support member and the left rotation support base are fitted on the first axis. The left rotation support base and the first axis are integrally connected to perform synchronous rotation. The left intermediate rotation support member is rotatably connected to the first axis. Both the right intermediate rotation support member and the right rotation support base are fitted on the second axis. The right rotation support base and the second axis are integrally connected to perform synchronous rotation. The right intermediate rotation support member is rotationally connected to the second axis.

[0009] Furthermore, the elastic member of the left intermediate rotation support member and the elastic member of the right intermediate rotation support member are both torsion springs and are connected to each other to form an integrated spring. Both end arms of the spring are respectively connected to the left intermediate rotation support member and the right intermediate rotation support member.

[0010] Furthermore, the integrated spring is provided with a left coil and a right coil. The left coil and the right coil are respectively fitted on the outside of the first axis and the second axis.

[0011] Furthermore, when the hinge is folded, the left intermediate rotation support member and the right rotation support member are driven by an elastic member and rotate downward until blocked by a limit in the middle casing of the mobile terminal. During the process from when the hinge is flatly opened to when the hinge is folded, the rotation angles of the left intermediate rotation support member and the right intermediate rotation support member are respectively smaller than the rotation angles of the left rotation support base and the right rotation support base. During the process from when the hinge is in a folded state to when it is flatly opened, when the hinge rotates to the support parts of the left rotation support base and the right rotation support base, the left intermediate rotation support member and the right intermediate rotation support member come into contact respectively. Then, the support parts rotate to positions where they move the left intermediate rotation support member and the right intermediate rotation support member to support the flexible screen. And at the flexible screen support position, the elastic member firmly presses the left intermediate rotation support member and the right intermediate rotation support member.

[0012] 〈The second problem to be solved by the invention〉 An object of the present invention is to provide a foldable flexible screen mobile terminal using the above hinge and obtain corresponding technical effects.

[0013] 〈Technical means for solving the second problem〉 The foldable flexible screen mobile terminal includes a middle casing, a left casing, a right casing, and an inner flexible screen, and further includes the above hinge. The left rotation support base and the right rotation support base are non-freely connected in the rotation directions of the left casing and the right casing respectively, and the left intermediate rotation support member and the right intermediate rotation support member correspond to the position of the middle casing.

Effects of the invention

[0014] By utilizing the technical means of the present invention, the present invention divides the middle support plate into two left and right intermediate support plates that do not rotate synchronously with the left and right rotation support bases. When the hinge is folded, the left and right intermediate support plates rotate downward under the drive of the elastic member and stop at the required position by setting the limit position, providing an appropriate clearance space at the lower end of the flexible screen bending part, reducing the conditions for the thickness of the middle casing, and lowering the conditions for the thickness of the middle casing. When the hinge is opened flat, the rigid support of the left and right rotation support bases can be obtained, and it is firmly pressed by the elastic member, and the gap between the left and right intermediate support plates also becomes smaller.

Embodiments for Carrying out the Invention

[0016] As shown in the drawings, the hinge provided by the present invention includes a left rotation support base 1 and a right rotation support base 2. The left rotation support base 1 and the right rotation support base 2 rotate around a first axis and a second axis respectively. The first axis and the second axis are parallel. In this embodiment, the axes of the left rotation support base 1 and the right rotation support base 2 are the first axis 10 and the second axis 20 respectively. A connection mechanism (such as a gear mechanism 6) that rotates synchronously in opposite directions is connected between the left rotation support base 1 and the right rotation support base 2. The axes of the left rotation support base 1 and the right rotation support base 2 rotate synchronously in opposite directions when the hinge is opened and when it is folded.

[0017] The hinge further includes a left intermediate rotation support member 3 and a right intermediate rotation support member 4. The left intermediate rotation support member 3 and the right intermediate rotation support member 4 correspond to the position of the middle casing 100 of the flip flexible screen mobile terminal. The left intermediate rotation support member 3 and the left rotation support base 1 are both fitted on the first axis 10. The left rotation support base 1 and the first axis 10 are connected by a flat portion and rotate synchronously. The shaft hole 30 of the left intermediate rotation support member 3 is a circular hole and is rotatably connected to the first axis 10. The right intermediate rotation support member 4 and the right rotation support base 2 are both fitted on the second axis 20. The right rotation support base 2 and the second axis 20 are connected by a flat portion and rotate synchronously. The shaft hole 40 of the right intermediate rotation support member 4 is a circular hole and is rotatably connected to the second axis 20.

[0018] The left rotation support base 1 and the right rotation support base 2 are respectively provided with support parts 11 and 21 when the hinges of the left intermediate rotation support member 3 and the right intermediate rotation support member 4 are opened flatly. When the hinge is opened flatly, the left intermediate rotation support part 3 and the right intermediate rotation support part 4 can obtain rigid support and firmly support the flexible screen.

[0019] An elastic member 5 is provided on each of the left intermediate rotation support member 3 and the right intermediate rotation support member 4. When the hinge is folded, the elastic member 5 rotates the left intermediate rotation support member 3 and the right intermediate rotation support member 4 downward and rotates them into the middle casing 100 of the mobile terminal. The elastic members 5 can be provided independently on the left and right, and preferably, they can also be provided integrally as in this embodiment. The elastic member of the left intermediate rotation support member 3 and the elastic member of the right intermediate rotation support member 4 are both torsion springs and are integrally connected. Both end arms 51, 52 of the spring of the integral structure are connected to the opening features 31, 41 in the left intermediate rotation support member 3 and the right intermediate rotation support member 4, respectively. The integral spring is provided with a left coil 53 and a right coil 54. The left coil 53 and the right coil 54 are respectively fitted on the outside of the first shaft 10 and the second shaft 20.

[0020] When the hinge of the flip-back mobile terminal corresponding to the hinge is in a flat open state, the torsion spring is in a state of storing energy. When the hinge is folded, the left intermediate rotation support member 3 and the right intermediate rotation support member 4 are driven by the elastic member 5 and rotate downward into the middle casing 100 of the mobile terminal until they are blocked by the limit. The limit can be installed in the middle casing. In the process from the state where the hinge is flat open to the state where the hinge is folded, the rotation angles of the left intermediate rotation support member 3 and the right intermediate rotation support member 4 are smaller than the rotation angles of the left rotation support base 1 and the right rotation support base 2, respectively. In the process from the hinge being folded to being flat open, when the hinge rotates to the support parts 11, 21 of the left rotation support base 1 and the right rotation support base 2, the left intermediate rotation support member 3 and the right intermediate rotation support member 4 come into contact with each other, respectively. Then, the support parts 11, 21 rotate to the positions where they move the left intermediate rotation support member 3 and the right intermediate rotation support member 4 to support the flexible screen, and at the positions where the flexible screen is supported, the elastic member 5 firmly presses the left intermediate rotation support member 3 and the right intermediate rotation support member 4 onto the support parts 11, 21.

[0021] The above hinge opens flatly, and the folding of the hinge corresponds to the flat opening and the folded state of the flip mobile terminal respectively. The left intermediate rotating support member 3 and the right intermediate rotating support member 4 can be in the form of plates to directly support the flexible screen, or support plates can be fixed to the left intermediate rotating support member 3 and the right intermediate rotating support member 4 respectively to support the flexible screen.

[0022] The flip flexible screen mobile terminal includes a middle casing 100, a left casing, a right casing, and an inner flexible screen. The left rotating support base 1 and the right rotating support base 2 are non-freely connected to the left casing and the right casing respectively. The left casing and the right casing use the first axis 10 and the second axis 20 as their rotation axes respectively. Support plates of the inner flexible screen are installed on the left casing and the right casing respectively.
