Abstract: A support stand for display device includes a base seat, an elevating support, and a locking module detachably connected the elevating support to the base seat. The locking module includes a fixing member, a rotating member, an elastic member, and a latching member. The fixing member is fixed on one of the base seat and the elevating support, and the fixing member defines a gap and a latching groove. The rotating member is rotatably extended through the other one of the base seat and the elevating support, and the fixing member. The elastic member is sleeved on the rotating member, and abuts on the fixing member. The latching member is fixed on an end of the rotating member. The latching member is extended through the gap of the fixing member, and is engaged in the latching groove of the fixing member.

Abstract: A support stand includes a support body, a connecting member, a fastening assembly. The support body defines an assembling hole. The connecting member is received in the assembling hole of the support body, and defines an engaging hole. The fastening assembly is positioned on the support body. The fastening assembly includes a follower. The follower has a positioning pole. The follower is movably connected to the support body, so that the positioning pole is capable of engaging/disengaging in the engaging hole of the connecting member.

Abstract: An exemplary dual-axis hinge mechanism includes a base seat, a first rotatable assembly and a second rotatable assembly. The first rotatable assembly includes a rotary member rotatably assembled in the base seat, a steady member and an elastic member non-rotatably received in the base seat, and a fastening member. The rotary member includes a rotational shaft configured for extending through the steady member, the elastic member, the base seat, and then engages with the fastening member. Each of the rotary member and the steady member defines an engaging surface. The engaging surfaces movably engage with each other. The fastening member is rotatable along the rotational shaft for adjusting an external force for rotating the rotary member. The second rotatable assembly includes a pivotal shaft fixed to the rotary member, and a bracket pivotally assembled on the pivotal shaft.

Abstract: An exemplary hinge assembly includes a rotatable shaft, a rotatable stand, a fixed stand, a restricting member, a cam, and a fastening member. The rotatable stand and the restricting member are non-rotatably connected to the rotatable shaft. The fixed stand and the cam are rotatably connected to the rotatable shaft. The cam is fixed to the fixed stand. The restricting member has a first restricting portion, the cam having a second restricting portion, the first restricting portion and the second restricting portion cooperatively define a rotating angle range between the rotatable stand and the fixed stand.

Abstract: A hinge assembly includes a pivot shaft, a first leaf, a fixing leaf, a restricting member, a deformable member, two limiting blocks, and a fastening member. The rotatable leaf is non-rotatably connected to the pivot shaft and the fixing leaf is rotatably connected to the pivot shaft. The restricting member and the deformable member are rotatably sleeved on the pivot shaft. The restricting member defines two positioning grooves. The deformable member includes a base plate and two protrusions extending substantially perpendicularly from the base plate. The limiting blocks are partially received in the positioning grooves and connected to the deformable member. When the rotatable leaf is rotated, the limiting blocks slide out of the positioning grooves to press the base plate of the deformable member such that the deformable member becomes elastically deformed. The fastening member is fixed on an end of the pivot shaft.

Abstract: An exemplary hinge assembly includes a rotatable shaft, a rotatable stand, a fixed stand, a restricting member, a cam, and a fastening member. The rotatable stand and the restricting member are non-rotatably connected to the rotatable shaft. The fixed stand and the cam are rotatably connected to the rotatable shaft. The cam is fixed to the fixed stand. The cam defines a restricting groove. A restricting piece is formed on the edge of the restricting member. The restricting piece engages in the restricting groove of the cam, thereby defining a rotatable angle range between the rotatable stand and the fixed stand.

Abstract: An exemplary hinge assembly (10) includes a base body (12), a bracket (14), a support board (18), a pivotal mechanism (16) and a rotational mechanism. The pivotal mechanism includes a pivotal shaft (163) fixed to the base body and rotatable relative to the bracket, an elastic member (165) and a fixing member (167). The rotational mechanism includes a rotational shaft (191), a rotary member (193), a steady member (195) and an elastic member (197). The support board and the rotary member are rotatable relative to the steady member, the base body, the bracket and the pivotal mechanism around a second axis. Each of the rotary member and the steady member defines an engaging surface (1932, 1951). One of the engaging surfaces forms at least one peak (1933), and the other of the engaging surfaces defines at least one valley (1953) corresponding to the peak.

Abstract: An exemplary double hinge assembly (30) includes a first hinge subassembly (31), a second hinge subassembly (32), a first bracket (35), a second bracket (36) and a connecting member. The first hinge subassembly (31) includes a first rotatable pivot shaft (311). The second hinge subassembly (32) includes a second rotatable pivot shaft (321). The first bracket (35) is fixed to the first rotatable pivot shaft (311), and the second bracket (36) is fixed to the second rotatable pivot shaft (321). The first hinge subassembly (31) and the second hinge subassembly (32) are rotatably mounted to the connecting member respectively. A rotating axis of the first rotatable pivot shaft (311) is substantially parallel to a rotating axis of the second rotatable pivot shaft (321). In addition, an electronic device (50) using the double hinge assembly (30) is also provided.

Abstract: An exemplary hinge assembly (100) includes a shaft (10), a follower (20), a cam (30), a sleeve, a first elastic element (60), and a second elastic element (65). The follower having a projection (23) is rotatable in unison with the shaft. The cam has a cam surface (31). The cam is located around the shaft, with the cam surface abutting against the projection. The sleeve is located around the shaft, and is non-rotatable relative to the cam. The first elastic element has a first arm (61) and an opposite second arm (63). The first elastic element is located around the shaft, with the first arm being fixed relative to the sleeve, and the second arm being fixed relative to the shaft. The second elastic element is located around the shaft and abuts against the cam to bias the cam toward the follower.
