Problems solved by technology

Since the switching piece is usually arranged at the axial position of the actuator to control the axial movement, it will inevitably increase the length of the entire pivot, which is not conducive to the miniaturization of the design of the pivot
In addition, the setting of the switching piece will also complicate the components, which in turn will affect the stability of the entire pivot action
[0004] 2. When the existing biaxial pivot is flipped from the closed state to 360°, biaxial displacement changes will occur, especially when it is flipped to a position of about 180°, the entire pivot will protrude from the notebook computer surface, making it difficult for the laptop to sit flat on the table

Abstract

The invention discloses a multi-section switching pivot device. The multi-section switching pivot device comprises a first shaft, a second shaft, an inner positioning plate, a torsion elastic piece set, an inner partition plate, a first concave and convex wheel set, a positioning partition plate, a second concave and convex wheel set, an outer partition plate and an outer positioning plate. One end of the first shaft and one end of the second shaft sequentially penetrate the inner positioning plate, the torsion elastic piece set, the inner partition plate, the first concave and convex wheel set, the positioning partition plate, the second concave and convex wheel set, the outer partition plate and the outer positioning plate, and the first shaft is located over the second shaft. Each of the first concave and convex wheel set and the second concave and convex wheel set comprises an upper concave wheel, a lower concave wheel and a middle convex wheel, wherein the middle convex wheel is provided with an upper protruding part and a lower protruding part, the upper concave wheel is provided with a short concave arc, and the lower concave wheel is provided with a long concave arc. The multi-section switching pivot device can be used for conducting multi-section type switching rotation on the first shaft and the second shaft without using switching devices such as switching pieces or switching pins, and therefore the pivot device can achieve large-angle rotation work.

Description

technical field [0001] The invention relates to the technical field of electronic equipment machinery, in particular to a multi-stage switching pivot device. Background technique [0002] Existing electronic devices, such as notebook computers, are usually designed with a display screen end that can be opened and closed relative to the host system end on the host system end, so that the display screen end can be opened when working, and can be stored and carried. Close the display screen side. In order to complete the aforementioned operations, taking a notebook computer as an example, a double-axis pivot is used to connect the system end and the screen display end. Although it can make the screen display end open upward or close downward with the pivot as the action axis On the system side, but there are the following disadvantages: [0003] 1. In the existing double-axis pivot device turning control mechanism, when it is necessary to bend a large angle, it is necessary t...
