360-degree dual-axis synchronous damping rotary shaft with tilting correction function

Abstract

The invention discloses a 360-degree dual-axis synchronous damping rotary shaft with a tilting correction function. The rotary shaft comprises two shaft cores, two worm gears, a worm and at least two limiting connection plates, wherein the two shaft cores are sleeved with the worm gears separately in a fixed mode, the two limiting connection plates are arranged on the two shaft cores in a sleeving mode correspondingly and located on the two sides of the two worm gears, and thus the two shaft cores are spaced by a set distance in the radial direction and can rotate freely in the circumferential direction relative to the two limiting connection plates; the worm is arranged in the containing space defined by the two limiting connection plates and the two worm gears, and the two sides of the worm are engaged with the two worm gears; and the two worm gears are different in external dimension but the same in number of teeth, or the two worm gears are different in both external dimension and number of teeth. Through the design, the two shaft cores of the dual-axis synchronous damping rotary shaft are in the tilting state at the zero degree and are in the tilting state or the vertical state at the 360 degrees so that the diversified requirements of people for forms of electronic equipment like notebook computers can be met.

Description

technical field [0001] The invention relates to a damping rotating shaft, in particular to a formal 360-degree dual-axis synchronous damping rotating shaft which can be tilted back. Background technique [0002] The damping shaft is a connecting element that can provide mutual rotation. It is mainly used between the rotating parts and its base. At present, it is widely used in various digital products and electronic equipment, such as notebook computers. The rotation of the damping shaft can realize The opening and closing function between the body of the notebook computer and the display screen. At present, the commonly used two-axis synchronous damping shaft realizes two-axis synchronous rotation through gear transmission or worm gear transmission, so as to realize the 360-degree opening and closing function of electronic equipment such as notebooks. Taking notebooks as an example, the notebook dual-axis synchronous damping in the prior art When the two axes of the rotati...
