Abstract: A display fine-adjustment device includes a display and a driving mechanism, the display being drivable by the driving mechanism to rotate; a support frame, which is connected to the display and includes supporting arms rotatably interconnected for being switchable between a folded condition and an expanded condition; and a sensor, which is electrically connected to the driving mechanism. A user manually pulls the support frame from the folded condition to the expanded condition to make the display fast approach the user and uses the sensor to detect the user and use the driving mechanism to drive the display to rotate to have the display facing the user, achieving an advantage of being time-saving and easy. In case of being not in use, folding can be made for space saving, while in use, the function of fine angle adjustment is performable to adjust the display to the most comfortable viewing angle.

Abstract: A chair structure with electronics support frame includes: a chair body, which includes an armrest; and an electronics support frame, which is located at one side of the armrest. The electronics support frame includes a mounting piece, a foldable pedestal, a claw part, a drive mechanism, and an image capturing device. The mounting piece is formed with an opening. The pedestal is arranged on the mounting piece. The pedestal includes multiple support arms rotatably connected to each other. The pedestal is switchable between a folded condition and an expanded condition. The claw part is arranged at one end of the pedestal and rotatable relative to the pedestal. The drive mechanism is electrically connected with the pedestal and the image capturing device. The image capturing device identifies a face position toward which the claw part is moved by the drive mechanism driving the pedestal.
