Worm gear transmission type 360-degree dual-axis synchronous damping shaft

Abstract

The invention discloses a worm gear and a worm driving type 360 DEG double-shaft synchronous damping rotating shaft, which comprises two shaft cores and at least two connection boards, one of a first worm and a second worm gear is selected on two shaft cores, and a first worm gear and a second worm are also arranged on the shaft cores; each first worm or second worm gear is sleeved and fixed on the corresponding shaft core, wherein two connection boards are positioned on two ends of two first worms or second worm gears, and sleeved on two shaft cores, distance between two shaft cores is radially set at interval, two shaft cores are rotated in an axial direction locking and circumferential free mode by facing two connection boards; the first worm gear or the second worm are positioned and arranged in an accommodation space enclosed by two connection boards and two first worms or second worm gears, and two sides radially faced to the first worm gear or the second worm are respectively engaged with two first worms or the second worm gears. The worm gear and worm driving type 360 DEG double-shaft synchronous damping rotating shaft can realizes double shaft synchronous 360 DEG rotatable open and close, and realizes limitless overturn function, and the damping rotating shaft enables perfect and smooth connection of the rotation position.

Description

technical field [0001] The invention relates to a damping rotating shaft, in particular to a 360-degree dual-axis synchronous damping rotating shaft of a worm gear transmission type. 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 rotating shaft is usually a single-axis core, and the 360-degree opening and closing and positioning functions of the notebook computer are realized by positioning the torsion unit sleeved on the single-axis core. There is also a dual-axis core structure to realize the opening and closing and positioning functions of the notebook computer; however, th...

Problems solved by technology

There is also a dual-axis core structure to realize the opening and closing and positioning functions of the notebook computer; however, this dual-axis core structure is usually that when one shaft core rotates, the other shaft core is locked, and the two shafts are sequentially opened and closed. Imperfect, cannot be synchronized

In order to achieve 360-degree synchronous rotation of the two shafts, there are also biaxial hubs that use multiple gears for combined transmission. The axes of the multiple gears are in the same direction as the axes of the two shafts. Dual-axis synchronous reverse opening and closing functions smoothly, and due to the use of more gears, the development of thinner electronic equipment such as notebooks is limited, and the installation and removal operations are more cumbersome
