A raising/lowering-type biaxial hinge for openably and closably coupling a first casing and a second casing in order that one type is compatible with terminal devices of different thicknesses is disclosed. The hinge is composed of a movable hinge shaft attached to a first casing, a fixed hinge shaft attached to a second casing, a first coupling member for movably coupling the movable hinge shaft and for rotatably bearing the fixed hinge shaft at a fixed position. A plurality of second coupling members for rotatably bearing the movable hinge shaft at a shift position and for movably coupling a first displaceable rotary shaft and a second displaceable rotary shaft is provided between the movable hinge shaft and the fixed hinge shaft.

A terminal device with a folding screen includes a coupling device with a middle frame fixing member, a first transmission assembly, a second transmission assembly and a third transmission assembly. A first transmission assembly is rotatable relative to the middle frame fixing member during rotation of the middle frame fixing member. The second transmission assembly has a first end hinged to the first transmission assembly and a second end slidably coupled to the first transmission assembly, and the second transmission assembly converts a rotation action of the first transmission assembly into a moving action along a second direction. A third end of the third transmission assembly pushes the middle frame fixing member to move towards a first side facing away from the first transmission assembly or a second side towards the first transmission assembly during the rotation of the middle frame fixing member.

A hinge includes: a base seat that includes a rack extending in a front-back direction; a moving platform that is movable on the base seat along the front-back direction; and a shaft unit that includes a rotating shaft rotatably extending through the moving platform in a left-right direction, a main gear member rotatably extending through the moving platform, co-movable with the moving platform, and meshed with the rack to constitute a rack and pinion system, and a first bevel gear piece fixedly sleeved on the rotating shaft, and meshed with the main gear member such that rotation of the rotating shaft results in collective linear front-back motion of the shaft unit and the moving platform relative to the base seat.

A display device includes: a display module; a first support part and a second support part disposed below the display module, the first and second support parts being arranged in a first direction; a hinge disposed between the first and second support parts below the display module to define biaxial rotation axes extending in a second direction intersecting the first direction; and a plurality of rotation parts coupled to the hinge to rotate about the biaxial rotation axes, the plurality of rotation parts being connected to the first and second support parts, respectively. Each of the rotation parts includes first and second parts that move relative to each other via a lost motion connection upon rotation of the rotation parts.

A hinge and a mobile terminal to resolve poor use effect of a foldable electronic device. The hinge includes a main body, and a first folding assembly and a second folding assembly that are symmetrically disposed along the main body. When the first folding assembly and the second folding assembly are rotated toward each other, a length of the hinge can be extended, and an accommodation space for accommodating the flexible display can be formed. When the first folding assembly and the second folding assembly are rotated away from each other, the length of the hinge can be reduced, and a support surface for supporting the flexible display can be formed, so that the flexible display cannot be stretched, compressed, or the like during folding and unfolding, thereby improving the use effect and safety of the mobile terminal.

A hinge includes: a base seat; two slide seats that are mounted on the base seat, that are movable between an inner position and an outer position, and that each have a slide rail portion; two rotary members that each have a slide portion being in sliding contact with the slide rail portion of a respective slide seat, and that are respectively rotatable relative to the slide seats; and two coupling mechanisms that are connected between the rotary members and the slide seats, such that rotations of the rotary members drive the slide seats to move between the inner position and the outer position. A distance between the slide seats decreases when the slide seats move from the outer position to the inner position.

A hinge structure is provided. The hinge structure includes a fixed structure including a first guide rail and a second guide rail, a center of an arc of the first guide rail is a first axis of rotation parallel to an axial direction and a center of an arc of the second guide rail is a second axis of rotation parallel to the axial direction, a first rotary structure including a first guide portion accommodated in the first guide rail and a first helical groove extending around and along the first axis of rotation, a second rotary structure including a second guide portion accommodated in the second guide rail and a second helical groove extending around and along the second axis of rotation, and a sliding structure including a first guide protrusion accommodated in the first helical groove and a second guide protrusion accommodated in the second helical groove.

A foldable hinge includes a base and two folding assemblies on both sides of the base and coupled to the base. The two folding assemblies are foldable relative to each other. Each folding assembly includes a rotating arm and a support member; a first end of the rotating arm is rotatably coupled to the base; the support member is rotatably coupled to a second end of the rotating arm away from the base; a side of the support member close to the base is rotatably coupled to the base and the support member is slidable in a direction approaching or away from the base. A distance between portions of two support members coupled to the rotating arms is smaller than a distance between portions of the two support members coupled to the base in response to bringing the two folding assemblies together.

An electronic device includes a first housing including a display module including a display screen, a second housing rotatable with respect to the first housing to define a rotation angle therebetween, the second housing including a first door provided at one surface and a second door provided at a surface which is opposite to the one surface, a hinge unit configured to rotatably connect the first housing to the second housing, and a driving module connecting the hinge unit to each of the first door and second door, the driving module moveable together with rotation of the second housing with respect to the first housing, to open and close the first door and the second door. the driving module is configured to open the first door when the rotation angle is less than a first angle and open the second door when the rotation angle is greater than a second angle.

A hinge apparatus may include a plurality of plates configured to be rigidly coupled to a foldable component, and a plurality of gears mechanically coupling the plurality of plates to one another. The hinge apparatus may be operable to expand such that, when the hinge apparatus transitions from a flat state to a folded state, the plurality of gears are configured to cause the plurality of plates to translate laterally apart from one another at a selected rate.
