Monitor supporting structure based on dual four-bar linkage balance control

A monitor supporting structure based on dual four-bar linkage balance control, comprising:

• a monitor bearing assembly, a support adjustment assembly, and a plane fixing assembly, the monitor bearing assembly being connected to the support adjustment assembly via a first rotating shaft and being used for fixing a monitor, and the support adjustment assembly being mounted on the plane fixing assembly via a second rotating shaft,
• wherein the support adjustment assembly comprises a connecting portion, a tension portion, and an auxiliary portion, the connecting portion comprises a first connecting end and a second connecting end, the tension portion is arranged between the first connecting end and the second connecting end and is used for balancing a torque generated by a force of gravity on the monitor, and the auxiliary portion is arranged on one side of the second connecting end, acts on the tension portion and is used for adjusting a tension generated by the tension portion;
• the auxiliary portion comprises a first link, a second link, and a movable block, the first link and the second link are arranged in parallel, ends of the first link and the second link are both hinged to the second connecting end, sides of the first link and the second link that are away from the second connecting end are hinged via a connecting block, and the movable block is hinged to the connecting block and is in contact with a side of the tension portion that is close to the second connecting end, so as to provide support for the tension portion;
• the tension portion comprises a bottom rod, a hinge block, an auxiliary block, and a tension spring, one end of the bottom rod is hinged to the first connecting end, and another end of the bottom rod is hinged to the second connecting end, a hinge point between the bottom rod and the second connecting end is lower than a hinge point between the first link and the second connecting end, the hinge block is hinged to the first connecting end, a hinge point between the hinge block and the first connecting end is higher than a hinge point between the bottom rod and the first connecting end, the auxiliary block is slidably connected relative to the bottom rod, one end of the auxiliary block is in contact with the movable block, and the tension spring is arranged between the other end of the auxiliary block and the hinge block;
• and
• the tension portion further comprises a housing and an adjustment component, the housing is arranged on an outer side of the tension spring and is used for guiding the tension spring, the adjustment component comprises a threaded rod, an adjustment block, and a feeding mechanism, the adjustment block is inserted into the housing, is slidably connected to the housing and is used for adjusting the tension spring, the threaded rod is threadedly connected to the adjustment block and is used for driving the adjustment block to move along a length direction of the housing, and the feeding mechanism is connected to the threaded rod and is used for driving the threaded rod to rotate;
• wherein the feeding mechanism is a pair of bevel gears that are arranged perpendicular to each other and mesh with each other or is a worm gear and a worm that are arranged perpendicular to each other.
