Problems solved by technology

However, the structure of the cam and the follower of this hinge structure is relatively complicated, and the cooperation of the cam and the follower can only stop the cover of the electronic device at the maximum flip angle
In addition, when the cover of the portable electronic device using this hinge structure is turned over to the maximum turning angle, the cover will hit the body, which will shorten the service life of the cover and the body.

Embodiment Construction

[0011] see figure 1 , the hinge barrel 20 of the preferred embodiment of the present invention is suitable for a folding or clamshell portable electronic device 100, and the specific embodiment of the present invention will be described by taking its application in a mobile phone as an example.

[0012] The portable electronic device 100 includes a hinge barrel 20 , a body 30 , a cover 40 and a filling block 50 . The hinge barrel 20 is connected to the body 30 and the cover 40 .

[0013] The machine body 30 is roughly a rectangular board, on which a plurality of buttons 31 are arranged. One end of the body 30 is provided with a mounting portion 32 and a fixing portion 33 opposite to each other. The mounting portion 32 is cylindrical, and a through hole 34 is defined at an end thereof. The through hole 34 is used for accommodating the hinge cylinder 20 . The fixing portion 33 is substantially the same shape as the mounting portion 32 , and a positioning post 332 extends fro...

Abstract

The invention discloses a hinge sleeve. The hinge sleeve is arranged in a portable electronic device. The portable electronic device comprises an engine body and a cap body; the hinge sleeve is provided with a notch, the notch is communicated with one side of the hinge sleeve, the surface of the hinge sleeve is provided with an uneven surface, the engine body is connected to the cap body in a rotating manner, and the cap body can rotate any rotation angle relatively to the engine body through the uneven surfaces. By using the hinge sleeve, the problem that when rotating to the maximum rotation angle, the cap body hits the engine body can be avoided, thus increasing the service life of the cap body and the engine body.

Description

technical field [0001] The invention relates to a hinge barrel and a portable electronic device using the hinge barrel. Background technique [0002] At present, the portable electronic devices sold on the market, such as mobile phones, PDAs (Personal Digital Assistants, personal digital assistants), etc., are mostly folding structures, that is, including a cover and a body. In order to connect the cover and the body, usually A hinge structure is used to connect the above two components. [0003] The existing hinge structure usually includes a main shaft, a cam, a follower and a spring. The cam cooperates with the cover body of the electronic device, and the follower cooperates with the body of the electronic device. This type of hinge structure realizes the opening and closing of the cover body relative to the machine body by overcoming the elastic force of the spring and making the cam surface of the cam and the cam surface of the follower move relatively. However, the ...
