  • Patent number: 8177175
    Abstract: The present invention discloses a digital mobile device and a stand module thereof. The digital mobile device includes a stand module comprising a fixing element and a rotating element. The fixing element is disposed on a side of the digital mobile device and includes an elastic element and a positioning member. The positioning member is disposed on a side of the elastic element. The rotating element is pivotally connected to the fixing element and has a positioning hole. The elastic element and the positioning member are disposed in the positioning hole. If the rotating element is rotated with respect to the fixing element, the elastic element will compress the positioning member to abut the fixing element, such that the fixing element and the rotating element are maintained at a positioning angle.

  • Patent number: 7591047
    Abstract: A bidirectional pivot structure includes a horizontal rotation axis module, a rotation switching device and a vertical rotation axis module. The rotation switching device is pivotally connected to the horizontal rotation axis module and the vertical rotation axis module. The vertical rotation axis module includes an aligning element, a rotation position limiting element, a stabilizing element, a flexible element and a locking element. The rotation position limiting element has a position limiting convex dot and a position limiting arc fitted to a guide rail and a position limiting protrusion of the aligning element for limiting the rotary angle of the vertical rotation axis module. The stabilizing element has a positioning convex dot and a stabilizing protrusion fitted to the positioning holes of the aligning element to maintain a frictional stability.
