Rotational-torsion-varying double-shaft synchronous rotation shaft apparatus

Abstract

The invention discloses a rotational-torsion-varying double-shaft synchronous rotation shaft apparatus, which includes a first shaft core, a second shaft core, a rotational torsion varying mechanism, a first shaft torsion part, a second shaft torsion part, and a linking part. The rotational torsion varying mechanism includes a first elastomer and a second elastomer, a transmission connecting plate, and a first transmission body and a second transmission body; the first transmission body and the second transmission body fixedly sleeve respectively the first and the second shaft cores; the transmission connecting plate slidingly sleeves the first and the second shaft cores; the first and the second transmission bodies are jointed to the transmission connecting plate through torsion friction surfaces with positions having different circumferential rotational torsions; the first and the second elastomers are elastically pressed against one side of the transmission connecting plate; the linking part, the first and the second shaft torsion parts are arranged at the other side of the transmission connecting plate. The apparatus can achieve double-shaft synchronous rotation and achieve real-time varying torsion in the rotation of the shafts. The apparatus has more usage functions, such as light opening and heavy closing, heavy opening and heavy closing, heavy opening and light closing, and light opening and light closing.

Description

technical field [0001] The invention relates to a double-shaft rotating shaft, in particular to a double-shaft synchronously moving rotating shaft device with variable rotational torque. 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 dual-axis shaft structure is usually that when one shaft core rotates, the other shaft core is locked, and the two shafts are opened and closed sequentially, which cannot be synchronized. Even though some dual-axis rotating shafts can realize dual-axis synchronous rotation through a combination of multiple gears, due to the use of many gears, the ...

Problems solved by technology

At present, the commonly used dual-axis shaft structure is usually that when one shaft core rotates, the other shaft core is locked. The two shafts are opened and closed sequentially, and synchronization cannot be achieved.

Even though some dual-axis shafts can realize dual-axis synchronous rotation through a combination of multiple gears, 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.

In addition, the existing two-axis synchronous shaft does not change the supporting torque during the rotation process, and has a single function, which cannot bring more experience to the user.
