Description

The pivot device structure-improved

Technical field

The utility model is about a kind of pivot device structure-improved, but refers to the function of vertical axial rotation especially, and pivot device structure that can ccontaining signal circuit passes through in the rotating shaft center.

Background technique

At present because the universalness of mobile communication, how the National People's Congress has carried a mobile phone now, not only can provide in the work and client or colleague between contact easily, even with household or friend between also need gradually to be used for maintaining interpersonal the interchange with interactive by making of device for mobile communication.

The prior mobile phone external form is by early stage banana machine modeling, develop to now, volume when carrying for dwindling, and provide different usage mode, and developed the design of shell machine gradually, it is so-called folding machine, display screen and body with operation keyboard are divided into the upper and lower covers structure and are superimposed together, and the two pivot joint is one with pivot, so device for mobile communication is not when using, the loam cake and the body that have display screen are to cover aspect, when using, again loam cake and body are launched to use, and in the design of phase at this moment, loam cake is still only can provide with expansion mode between body and makes the relative body of display screen lift the function of directions such as opening and cover.

But after digital camera lens application use is on mobile communication product, because the device for mobile communication auto heterodyne is provided, clap people's function, in order to make the user at the device for mobile communication that uses the folding mode design, can be convenient to control flexibly the digital camera lens that is arranged on the display screen loam cake, so someone has done further improvement design at pivot section, developed a kind of pivot device structure of doing the vertical axial rotation, it not only can provide LCD Display to do with respect to body and start, the action that covers, and can raise the back and rotate 180 degree at display screen, make that display screen can be toward the outer side, make the user be convenient to take pictures or watch the picture of display screen.

Existing pivot device structure, though can reach covering and starting of control display screen, and can provide another pivot structure, make the display screen that is arranged on this pivot structure can do the rotation of vertical axial, but because in the existing pivot device structure, the pivot structure that provides vertical axial to rotate, can not hold the signal circuit, feasible device for mobile communication in the past is in the process of assembling, be connected to the signal circuit of display screen and digital camera lens by body, all must do the cabling design along the pivot structure outer surface, make the RCA rood extending to loam cake, but, tend to take place the RCA route is done vertical axial for a long time in the display screen loam cake rotation because of in the process of using by internal body, and then cause the RCA Louis in being pullled, become flexible or damage and cause.

Summary of the invention

The utility model main purpose is to provide a kind of pivot device structure-improved, mainly is to make pivot device have the function that vertical axial rotates.

Another purpose of the utility model, be to provide a kind of pivot device structure-improved, be to make pivot device that the pivot element of vertical axial rotating function is provided, can pass through by ccontaining signal circuit, with avoid being subjected to pivot element rotate and have be damaged may, use and reach the effect that reduces hazard rate.

For reaching above-mentioned purpose, the utility model mainly is to be respectively arranged with one first pivot element and second pivot element on the fixed base of pivot device, the substantially horizontal folding is provided respectively, and the function of vertical axial rotation, and rotary seat and rotating shaft centre in second pivot element, be penetrated with the structure of a through hole, pass through in order to ccontaining signal circuit, make when second pivot element is rotated, do not cause the RCA road to cause damage, so can significantly reduce the generation of hazard rate because of being subjected to any pullling.
