Problems solved by technology
However, the elastic body is prone to elastic fatigue after many rotations. In addition, the cam is very easy to wear and tear is also a problem. A severely worn cam may cause the elastic body to lack elasticity due to insufficient deformation during use.
It can be seen from the above that repeatedly rotating the button part of the above-mentioned mobile phone may cause the rotation mechanism to fail to work normally, which may cause the above-mentioned mobile phone to be unable to use normally
In addition, if the user needs to use the above-mentioned rotating mechanism to rotate the key part of the mobile phone 180 degrees relative to the display part, so that the camera on the key part and the display screen of the display part are located on the same side of the mobile phone, external force must be continuously applied until the key part rotates relative to the display part 180 degrees, inconvenient to operate

Embodiment Construction
[0015] like Figure 1 to Figure 3 As shown, the electronic device 100 includes a first component 200 , a second component 300 , a rotating device 400 , four screws 500 and a signal line 600 . The rotating device 400 connects the first part 200 and the second part 300 , and the second part 300 can rotate relative to the first part 200 .
[0016] The first component 200 is roughly rectangular, and one side thereof is partially recessed to form a first accommodating portion 210 . A fixing groove 212 and two first fixing holes 214 are provided on the bottom surface of the first accommodating portion 210 . The two first fixing holes 214 are respectively located on two sides of the fixing groove 212 and are symmetrical with respect to the fixing groove 212 .
[0017] The rotating device 400 includes a rotating shaft 450 and a first magnetic body 440 , a washer 430 and a second magnetic body 420 sleeved on the rotating shaft 450 in sequence. The rotating shaft 450 is a hollow cylin...

A rotation device is used for connecting a first component with a second component of an electronic apparatus so that the second component can be rotated opposite to the first component, the rotation device comprises a first magnet and a second magnet arranged corresponding to the first magnet, the first magnet is fixed on the first component; the second magnet is fixed on the second component and one side thereof corresponding to the first magnet has opposite polarity in order to increase an action force between the first component and the second component so that the second component, after being rotated by any angle between 90 degrees and 270 degrees opposite to the first component under the action of external forces, can automatically rotate and be stable in a status of rotation of 180 degrees opposite to the first component, the operation is easy and upon repeated rotation, the first magnet and the second magnet can still operate normally, thus improving reliability of the rotation device and the electronic apparatuses using the rotation device. The invention further provides a cell phone and an electronic apparatus using the rotation device.
Description
technical field [0001] The invention relates to a rotating device and a mobile phone and electronic equipment using the rotating device. Background technique [0002] With the development of technology, mobile phones have become an indispensable item in modern human life, and in order to make their products occupy a place in the market, all manufacturers introduce new and convenient mobile phones to attract the attention of consumers. For example, a rotating mechanism is added to the mobile phone so that the key part can rotate 180 degrees relative to the display part, so that the camera on the key part and the display screen on the display part are located on the same side of the mobile phone, so that users can see themselves through the display screen when taking selfies photos for easy selfies. [0003] Usually, the above-mentioned rotating mechanism is a hinge composed of elastic bodies such as cams and springs, and the display screen of the mobile phone is stabilized a...
