Description

Shaft with sliding torsion mechanism

technical field

The utility model relates to a rotating shaft with a sliding torsion mechanism, in particular to a rotating shaft whose specific torsion force can slide at any angle along with the rotation of the rotating shaft.

Background technique

Generally, foldable electronic devices include a body and a screen with a cover attached to the body, such as notebook computers, mobile phones or personal digital assistants, etc. A rotating shaft is installed between the body and the screen so that the screen can be flipped open for operation. For relatively large electronic devices such as notebook computers, in order to make the screen stably stagnate at the angle of rotation when the screen rotates, the shaft usually requires a relatively large torque. Usually, when the user opens the screen, he will first tilt it to an angle, and then slightly adjust the angle of the screen to facilitate the operation. However, the large torsion force makes it difficult for the screen to rotate back and forth to adjust the angle. Although the small torque allows the screen to be easily rotated to adjust the angle after opening, but when the screen is closed down, due to insufficient support, the screen cannot stay at any angle, but will automatically fall and cover to the body , produces a greater impact on the body, and at the same time, it cannot meet the user's demand for the screen cover to be stagnant at any angle when it is closed.

Utility model content

The main purpose of this utility model is to provide a rotating shaft with a sliding torsion mechanism. When the assembly fixed on the screen of the folding electronic device is turned to any angle, the rotating shaft will be within a specific angle range of its return.

At this time, the assembly can adjust the angle back, at the first Within the range of the angle between the sidewall and the second sidewall, the assembly can drive the control piece to rotate synchronously back and forth, thereby generating a small frictional torque to easily adjust the angle of the screen. When the assembly piece is rotated back and closed, when the second rib stops against the restricting surface of the restricting shaft, the control piece stops rotating, and the assembly piece rotates by friction relative to the control piece, thereby generating a relatively large torsion force , so that the screen can stop at any angle when it is closed down, so as to avoid automatic falling and closing.

When the shaft 21 rotates, its first rib 311 can stop against the first restricting surface 221 restricting the shaft 21 , and the restricting control piece 3 continues to rotate. When the control piece 3 rotates in the reverse direction, its second rib 312 blocks against the second limiting surface 222 of the limiting shaft 21 , and restricts the control piece 3 from continuing to rotate in the reverse direction.

A locking member 4 includes a first positioning block 41 , a second positioning block 42 and an elastic element 43 , and is sequentially passed through the limiting shaft 21 to provide an automatic locking function. The first positioning block 41 passes through the limiting shaft 21 with a shaft hole 411 , and is embedded in the fixing hole 13 of the assembly 1 with a protruding fixing column 412 to rotate synchronously with the assembly 1 , and The control piece 3 is arranged between the assembly part 1 and the first positioning block 41 .
