Hinge mechanism and portable electronic device using the same

The invention relates to a hinge mechanism and a portable electronic device using the same.

With the rapid development of wireless communication technology and information processing technology, portable electronic devices such as mobile phones and PDAs (Personal Digital Assistants) enable consumers to enjoy the convenience brought by high technology anytime and anywhere. Electronic devices are popular among consumers because of their exquisite structure.

The folding electronic device usually connects the body and the cover body by a hinge mechanism. The conventional hinge mechanism usually includes a sleeve, a cam, a follower and a spring. The spring is sleeved on the sleeve, and one of the cam and the follower is in direct contact with the spring, and the cam and the follower are always maintained under the elastic force of the spring. Contact and match. This type of hinge mechanism realizes the opening and closing of the cover body relative to the body by overcoming the cam surface of the cam and the cam surface of the follower against the elastic force of the spring.

However, the hinge mechanism has many components and a complicated structure.

In view of this, it is necessary to provide a hinge mechanism having a simple structure.

It is also necessary to provide a portable electronic device to which the hinge mechanism is applied.

A hinge mechanism for hinged a body of a portable electronic device to a cover body The hinge mechanism includes a fixing member that is fixedly coupled to the body and a rotating member that is fixedly coupled to the cover body. The hinge mechanism further includes a columnar elastic member, and the cylindrical elastic member is fixed at one end. The other end of the rotating member is fixed to the fixing member. When the rotating member rotates relative to the fixing member, the cylindrical elastic member is twisted to accumulate the torque. After the rotating member is released, the rotating member is at the torque The first protruding block and the second protruding block are configured to be engaged with the cover body.

A portable electronic device includes a cover body, a body and a hinge mechanism. The hinge mechanism includes a fixing member fixed to the body and a rotating member fixed to the cover body. The hinge mechanism further includes a columnar elastic member, one end of the columnar elastic member is fixed to the rotating member, and the other end is fixed to the fixing member, and when the rotating member rotates relative to the fixing member, the columnar elastic member is twisted to accumulate Torque force, after the rotating member is released, the rotating member performs a returning movement under the action of the torsion force. The fixing member is provided with a first protrusion and a second protrusion. The cover body is closed when the cover body is closed relative to the body. When the cover is engaged with the first protrusion, the cover is engaged with the second protrusion when the cover is opened relative to the body.

Compared with the prior art, the hinge mechanism and the portable electronic device using the hinge mechanism only need to provide a columnar elastic member between the fixing member and the rotating member, so that the cover body and the body can be realized. The articulation thus has the advantage of being structurally simple relative to prior art techniques.
