Background

A hinge is a mechanical device used to connect two solids and allow relative rotation between them. The hinge may be constructed of a movable component or may be constructed of a foldable material. Hinges currently on the market can be broadly divided into: the hinge comprises four types of one-way hinges, free stop hinges, rotary hinges and automatic hinges. The first two hinges can realize rotation in one direction, have simple structure and low price, and are widely applied to mobile phones. The latter two hinge structures are complex relative to the former two. For example, taiwan bulletin No. M325719 includes a positioning seat, a main rotating seat capable of rotating relative to the positioning seat, and a rotating member located below the positioning seat, wherein the positioning seat has at least one accommodating portion, the accommodating portion is configured with at least one touching member and an elastic unit located above the touching member and abutting against the touching member, the accommodating portion includes at least one through hole, the touching member is positioned in the through hole and exposed out of the accommodating portion, the touching member is provided with at least one groove, and the touching member and the rotating member move up and down relative to the through hole toward a top surface in a rotating stroke of the main rotating seat.

Can drive in the above-mentioned patent of disclosing and revolve the piece and make the recess break away from and touch the piece through main revolving seat rotation time to moment of torsion when providing the rotation, however, the positioning seat needs set up the equipment space in addition in order to install elastic element, thereby leads to rotatory hinge thickness to increase bulky, can not satisfy the requirement of the small volume of present electronic device.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a sandwich type the hinge mechanism, adopt sandwich type built-up mounting mode, reduce the volume of hinge mechanism, be applicable to the use of small-size electronic product to improve rotatory hinge's application scope.

The technical scheme of the utility model as follows:

a sandwich type hinge mechanism comprises a rotating arm, an upper supporting arm, a lower supporting arm, a center frame, a center shaft, a rotating shaft and a guide wheel.

The rotating arm comprises a connector and a fluted disc, the connector is provided with a plurality of mounting holes, the center of the fluted disc is provided with a circular through hole, and external meshing teeth are uniformly distributed on the fluted disc except the connector.

The upper supporting arm and the lower supporting arm are the same in structure and comprise an installation disc and an installation arm, the disc is of a circular ring structure, the center of the disc is a circular through hole, and the installation arm is provided with a rotating shaft, a guide wheel and an external connecting object.

A rotating arm is arranged between the upper supporting arm and the lower supporting arm, a central frame is arranged at the center of the fluted disc and the disc, and the connecting body and the mounting arm are reversely arranged; a rotating shaft is arranged between the mounting arms of the upper support arm and the lower support arm, and the guide wheel is mounted on the rotating shaft and rotates around the rotating shaft; the central shaft is arranged in the central hole of the central frame.

The center frame is of a ring groove shell structure, and a center hole of the center frame is an inner hexagonal hole and is provided with a center shaft.

The guide wheel is an external gear and is meshed with external meshing teeth of the fluted disc.

The utility model discloses an effect and benefit are:

(1) the sandwich hinge mechanism has the advantages of simple structure, convenient installation and simple operation process;

(2) the adoption sandwich type combination mounting mode reduces the volume of the hinge mechanism, and the swinging boom rotates around the centre frame to carry out the fixed of turned angle through the leading wheel, be applicable to small-size electronic product's use, with the application scope who improves rotatory hinge.
