Description

Technical Field

[0001] The present invention relates to the field of screen bracket equipment, and in particular to a folding bracket and a display. Background Art

[0002] Monitors are used to display pictures and images and are widely used in work and life. Monitors require brackets for support and installation to meet the display and viewing needs in different directions or positions. Existing monitor brackets generally only provide the functions of rotating around the axis and lifting and lowering, and the adjustment mechanism is large. In order to increase the load of the monitor and achieve different display effects, the screens need to be used in combination. Therefore, a monitor bracket with a large load capacity and the ability to be lifted, lowered, and rotated in one direction is needed.

[0003] Patent application CN118578878A discloses a motorized rear flip display screen mechanism for an automotive instrument panel. The mechanism comprises a large screen, a screen mounting base, a screen mounting cover, a screen rotation axis, a screen rotation axis fixing base, a drive motor, and a fixing bracket. The large screen is fixed to the screen mounting base with screws. The screen mounting base is connected to the screen rotation axis fixing base via the screen rotation axis. The screen rotation axis fixing base is fixed to the fixing bracket with screws. The screen mounting base is also fixed to a screen rotation drive rack with screws. The screen rotation drive rack matches a drive gear, which is connected to the drive motor. This flip display screen can only be raised or lowered in a single rotation direction, resulting in limited height adjustment and a large space occupied by the adjustment mechanism.
