Stop fixing mechanism, and notebook computer rotating shaft based on stop fixing mechanism

Abstract

The invention discloses a stop fixing mechanism, and a notebook computer rotating shaft based on the same. The stop fixing mechanism comprises a rotating sleeve rotatably sleeved on the rotating shaft, a suspension groove is formed between the rotating sleeve and the rotating shaft, and the rotating sleeve is not contacted when rotating relative to the rotating shaft; when the rotating sleeve is fixed relative to the rotating shaft, the rotating sleeve and the rotating shaft are fixed in a suspended mode through the second magnetic plates and the first magnetic plates which repel each other, and the rotating sleeve and the rotating shaft are fixed in a suspended mode through the multiple sets of second magnetic plates and the multiple sets of first magnetic plates which repel each other; when the rotating sleeve is rotated, the rotating sleeve rotates relative to the rotating shaft; and when the rotating sleeve rotates to a fixing position, the rotating sleeve and the rotating shaft are fixed at any time through the second magnetic plates and the first magnetic plates which repel each other, so the mode that the rotating shaft structure is prone to abrasion due to direct contact isavoided, the rotating sleeve is convenient to rotate and fix, the structure is not prone to abrasion, lubrication is not needed, and the phenomenon that dust is prone to being adsorbed by lubricatingoil is avoided.

Description

technical field [0001] The invention relates to the technical field of notebook computer shafts, in particular to a stop-stop mechanism and a notebook computer shaft based on the mechanism. Background technique [0002] Laptop shafts often use damping shafts. The most common problem with damping shafts in use is the wear of the gaskets between the shafts, which is also a common equipment problem during the use of the shafts. Although the hardness is high, it has poor yield (unrecoverable after deformation), poor impact resistance, and poor fatigue resistance, so it is easy to cause adhesive wear, abrasive wear, fatigue wear, and fretting wear. [0003] And the position of the damping shaft is easy to hide dust, which will reduce the heat dissipation of the notebook computer for a long time; for this reason, we provide a stop and fix mechanism and a notebook computer shaft based on this mechanism to solve the above problems. Contents of the invention [0004] Aiming at the...

Problems solved by technology

[0002] Laptop shafts often use damping shafts. The most common problem with damping shafts in use is the wear of gaskets between shafts, which is also a common problem during the use of shafts. Equipment problems are mainly caused by the metal characteristics of the shaft gasket: although the metal has high hardness, it has poor yield (cannot be restored after deformation), poor impact resistance, and poor fatigue resistance, so it is easy to cause adhesive wear, abrasive wear, and fatigue wear , fretting wear, etc.
