A rotating shaft assembly and electronic equipment

Abstract

The present application provides a rotating shaft assembly and an electronic device. The rotating shaft assembly includes: a rotating shaft bracket and a rotating shaft, and the relative rotation between the first housing and the second housing of the electronic device is realized through the rotation between the rotating shaft bracket and the rotating shaft. The rotating shaft includes a first matching area and a second matching area; the second matching area includes a plurality of pressing areas arranged around the axis of the rotating shaft; the rotating shaft bracket and the first matching area are in interference fit; and a swing arm arranged on the rotating shaft bracket is also included , and the swing arm is pressed against the second matching area; along the opening direction of the electronic device, the frictional force between the swing arm and the multiple pressing areas gradually increases. The additional damping force is provided by the damping force between the second mating area and the swing arm, and the damping force of the swing arm and the second mating area can gradually increase with the opening angle of the first shell and the second shell, so that When the electronic device is just opened, a small damping force is provided, and as the opening angle increases, the damping force gradually increases, so that the electronic device can be kept in an open state.

Description

technical field [0001] The present application relates to the technical field of terminals, in particular to a shaft assembly and electronic equipment. Background technique [0002] As a key component of electronic equipment, the hinge assembly is a bridge connecting different main bodies of electronic equipment. The different main bodies of electronic equipment are connected by hinges to achieve relative rotation to control the relative angle to meet the requirements of comfortable user experience. For example, a laptop is connected to the screen through a hinge assembly. Part and the host part, the screen is rotated to a certain angle and fixed through the rotating shaft assembly during work. [0003] One-handed opening of electronic devices, especially laptops, is a very important user experience. The greater the torque of the shaft assembly, the less it is possible to open it with one hand, but the torque is too small to meet the stability of the screen at the angle of u...

[0003] One-handed opening of electronic devices, especially laptops, is a very important user experience. The greater the torque of the shaft assembly, the less it is possible to open it with one hand, but the torque is too small to meet the stability of the screen at the angle of use. The lighter the screen of the laptop The easier it is to open with one hand, and vice versa; the lighter the host is, the harder it is to open it with one hand, and the easier it is to open it with one hand; but under the current trend of lightweight notebooks and touch screens, the weight of the host is heavier Lighter and lighter, the weight of the screen part is getting heavier, and the problem of "top-heavy" in weight is becoming more and more obvious. It is becoming more and more difficult to open the laptop with one hand using the constant torque shaft assembly
