Hollow multi-segment self-closing damper rotating shaft

Abstract

The invention discloses a hollow multi-segment self-closing damper rotating shaft, and the damper rotating shaft comprises an axial hollow shaft core and a first bracket, wherein one end of the axial hollow shaft core is fixedly connected with the first bracket while the other end of the axial hollow shaft core is sequentially provided with a second bracket, a concave wheel and a cam in a sleeving manner; both the second bracket and the concave wheel are fixedly connected in a positioning manner and can freely rotate with respect to the axial hollow shaft core; the cam can peripherally stop and axially and automatically slide relative to the axial hollow shaft core; one side of the concave wheel, facing towards the cam, is at least provided with a groove group including two grooves arranged at an space; one side of the cam, facing towards the concave wheel, is provided with a boss group including two first bosses corresponding to the two grooves in each groove group, and each first boss can slide into and slide off the corresponding groove. The hollow multi-segment self-closing damper rotating shaft can perform 360-degree free rotation and has multi-segment self-closing functions so that a relatively good experience effect can be provided for users, so that the damper rotating shaft can also meet the two-way self-closing demand of a notebook computer and other products.

Description

technical field [0001] The invention relates to a damping rotating shaft, in particular to a hollow multi-section self-closing damping rotating shaft. 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 damping shaft can realize the rotation of the notebook computer. Mutual rotation between the body and the display screen. [0003] At present, the commonly used damping shaft with automatic closing structure usually includes a shaft core and a cam and a concave wheel that are sleeved on the shaft core. The concave part of the concave wheel and the convex part of the cam cooperate to realize the function of automatic closing. However, The concave wheels and cams in the prior art can only realize one-stage automatic closing, which cannot meet people’s ...

Problems solved by technology

In addition, with the development of lighter and thinner notebook computers, higher requirements are put forward for the cooperation of damping shafts and wires. However, the commonly used damping shafts are usually solid cores, which is not conducive to matching with related wires and saving space.
