Abstract: A head-mounted display apparatus includes a wearing device, a display-source arrangement portion and an optical assembly. The wearing device has a head-wearing portion and a hat brim portion connected to the head-wearing portion. The display-source arrangement portion is connected with the hat brim portion. The optical assembly is movably disposed on the hat brim portion, and arranged between the head-wearing portion and the display-source arrangement portion.

Abstract: A wearable display device includes a wearing device, a fixed frame, a sliding member, a bracket and an optical imaging device. The fixed frame is fixedly connected to the wearing device. The sliding member is slidably coupled to the fixed frame. The bracket is pivotally connected to the sliding member and is interlocked with the sliding member. The optical imaging device is fixedly connected to the bracket for sliding and rotating relative to the fixed frame.

Abstract: A head-mounted display device includes a wearable device, a display module, a fixing rack and a connecting rod module. The wearable device is used to be placed on a human head. The display module is used to cover human eyes. The fixing rack is fixedly connected to the wearable device. The connecting rod module includes a support arm and a sliding member. The support arm is pivotally connected to the fixing rack. The sliding member is fixedly connected to the display module, and slidably engaged with the support arm and the fixing rack.

Abstract: A hinge assembly is provided. The hinge assembly includes a rotating shaft structure, a first movable assembly and a second movable assembly. The rotating shaft structure includes a first rotating part and second rotating part. The first rotating part coaxially rotates relative to the second rotating part. The first movable assembly includes a first connecting member and a first moving member. The first moving member is movably connected to the first connecting member. The first movable assembly is connected to the first rotating part to rotate with the first rotating part simultaneously. The second movable assembly includes a second connecting member and a second moving member. The second moving member is movably connected to the second connecting member. The second movable assembly is connected to the second rotating part to rotate with second rotating part simultaneously.

Abstract: An electronic device is provided. The electronic device includes a conductive housing, a first antenna element, a second antenna element and an insulation structure. The first antenna element is disposed in the conductive housing. The second antenna element is disposed on an external surface of the conductive housing and is opposite to the first antenna element. The conductive housing generates a first current in response to the operation of the second antenna element. The insulation structure penetrates through the conductive housing and extends from at least one side of the conductive housing to the second antenna element. The conductive housing generates an induction current in response to the operation of the first antenna element. The insulation structure blocks the induction current so that the conductive housing generates a second current, and a direction of the first current is the same as a direction of the second current.

Abstract: An electronic device including a main body, a support arms, and a display is provided. The main body has a positioning portion. A first end of the support arm is pivoted to the main body, and the support arm is telescopic. A second end of the support arm is pivoted to the display. When the display is opened, the support arm rotates such that the display stands, and the display is driven to rotate by retracting the support arm to adjust a tilting angle of the display. At this time, an edge of the display is supported on the positioning portion of the main body.
