Description

Torsion deformable pivot

This creation relates to the technical field of a pivot device, in particular to a torsionally deformable pivot device with a structure in which two opposite cams move relative to each other by a convex block and an inclined surface.

A notebook computer has a host and a screen. The screen is usually connected to the host by a pivot device. When the user is not using the notebook computer, the screen can be covered on the host by the pivot device. When the user needs to use the notebook computer, the user rotates the screen relative to the host by the pivot device and uses it.

When opening the screen of the existing notebook computer pivot, the user has to overcome the friction between the shaft holes, which is more laborious to open the screen, and when the screen is opened to a desired angle, for example, when the screen is opened to a desired angle, the user has to overcome the friction between the shaft holes. When the angle reaches 90 degrees, the screen is easy to shake.

As shown in Figure 1, the existing pivot has a first cam A1 and a second cam A2 that abut against each other. The first cam A1 has a recess A11, and the second cam A2 abuts against a torque module B and It has a convex part A21. The convex part A21 of the second cam A2 enters the concave part A11 from the plane of the first cam A1, so that the screen connected by the pivot can be opened to a positioning angle with less effort. The convex part A21 rises from the concave part A11 of the first cam A1 to the plane, so that the screen needs to be opened larger The angle must be laborious, so that the screen is not easy to shake at the positioning angle. However, the above-mentioned structure will cause a sudden change in the torque, which makes the process of turning the screen open by the user prone to unsmooth problems.

In view of this, the purpose of this creation is to provide a torsion deformable pivot, which enables the screen and the host connected to the torsion deformable pivot to provide different torque values in different angle ranges, and to change the torque value Gentle, so that users can easily and smoothly open the screen, and after the screen is opened to a desired angle, it can prevent the screen from shaking.

The torsion module includes a plurality of torsion members, which are relatively rotatably disposed on the shaft body, and the torsion module abuts against the first cam member or the second cam member. The second cam member rotates relative to the first cam. When a first angle is formed between the first connecting member and the second connecting member, the protrusion is located on the first inclined surface. When a second angle is formed between the second connecting pieces, the bump moves from the The first inclined surface moves to the plane, and when a third angle is formed between the first connecting member and the second connecting member, the bump moves from the plane to the second inclined surface, and the first angle is smaller than the second angle , The second angle is smaller than the third angle.

The torsion-deformable pivot of the present invention abuts against the first inclined surface, the plane and the second inclined surface of the first cam member by the convex block of the second cam member, so that when the convex block descends to the plane on the first inclined surface, the torsion force The torque of the module is released, and the torque value gradually decreases, so that the screen can be opened smoothly and effortlessly. Then the bump is located between the first inclined plane and the second inclined plane. If the screen is to be opened to a larger angle, the bump will rise from the plane from the second inclined plane, so that the torsion element of the torsion module is compressed, and the torque value gradually Make it larger, so that the screen will not shake after being opened to the position.
