Description
Technical field
The utility model relates to a kind of portable terminal, particularly a kind of portable terminal with rotary camera.
Background technology
The develop rapidly of mobile communication technology is had higher requirement to the miniaturization and the structural compactness of portable terminal, simultaneously owing to the development of 3G (3G (Third Generation) Moblie technology), the demand of video communication make camera become parts of portable terminal indispensability.And FPC (Flexible Printed Circuit, flexible PCB) is exactly the camera data wire connected mode that is widely used on the portable terminal.
Because the compactedness of structure, the extension of camera FPC has great influence to the antenna performance of closing on it.In the rotating camera design, camera turns to different angles, and corresponding camera FPC has the attitude of continuous variation, under the radio circuit operating state, the earth-current on FPC surface distributes and also changes along with the variation of FPC attitude, and this moment, the antenna performance of portable terminal was had a strong impact on.
The rotating camera structure is a kind of device that can reach the broadening visual angle by the rotation camera, and its camera data wire connected mode adopts the FPC structure usually, and FPC encloses so that enough stretching, extension, shrink space to be provided around two in rotating shaft.
The lead of camera FPC is a metal material, links to each other with mainboard, and portable terminal is in the wireless receiving and dispatching process, and camera FPC surface induction goes out high-frequency current, and external radiated electromagnetic wave.Because camera FPC is near mobile terminal antenna, its CURRENT DISTRIBUTION has a significant impact the radiance of antenna.When camera turned to different conditions, FPC Internal and external cycle attitude changed, and the spacing of Internal and external cycle changes and to cause the Internal and external cycle degree of coupling to change, and its surface current produces very great fluctuation process.The complete machine radiation characteristic of portable terminal is the stack of its each several part radiation, and the variation of FPC surface current causes portable terminal near field, far-field radiation changes of properties.The near-field thermal radiation changes of properties has influence on portable terminal SAR (SpecificAbsorption Rate, specific absorption rate) index, the far-field radiation changes of properties has influence on the validity of radiofrequency signal of mobile terminal transmitting-receiving, and the uncertainty of mobile terminal antenna radiance makes troubles to production testing, has greatly influenced production efficiency.
Experiment confirm is when camera turns to different directions, with the test result of the dull and stereotyped coupled antenna of device the most frequently used in the portable terminal production testing, have the fluctuation of up 10dB, the complete machine far-field pattern also fluctuates very big, and directivity changes, and near field SAR index uncertainty is very big.Therefore in order to improve the wireless receiving and dispatching performance of portable terminal, the variation of FPC surface current causes portable terminal near field, this problem of far-field radiation changes of properties to solve.
The utility model content
The technical problem that the utility model solved has been to provide a kind of portable terminal with rotary camera, to reach when camera turns to different conditions, the variation that FPC Internal and external cycle attitude takes place does not influence portable terminal near field, far-field radiation changes of properties.Thereby the fluctuation that complete machine aerial radiation power is caused diminishes, and far-field pattern stability improves, and near field SAR index keeps stable effect.
For solving the problems of the technologies described above, the utility model provides a kind of portable terminal with rotary camera.Comprise: camera rotating shaft 5, camera flexible PCB 4, the described rotating shaft of described flexible PCB 4 windings was drawn after 5 several weeks, be connected on the portable terminal mainboard, form flexible PCB inner ring 6 and outer ring 7, this portable terminal also comprises flexible circuit plate positioning device 1, between described flexible PCB inner ring 6 and outer ring 7.
Described flexible PCB outer ring 7 can be supported by described positioner 1.
Described flexible PCB outer ring 7 can stride across described positioner 1 and link to each other with the portable terminal mainboard.
Described positioner can be fixed on the sidewall of camera support.
Described positioner can be fixed on the mobile terminal case.
Described positioner can extend out from described portable terminal mainboard.
Because the utility model is in the design of mobile terminal antenna, not only it is designed as single parts, but PCB (Printed Circuit Board) plate and extension thereof all are considered as the part of antenna, whole portable terminal is designed as an antenna system, thereby the defective that the Antenna Design that has solved present portable terminal designs as an isolated part usually reaches the purpose of adjusting antenna performance on the whole by the structure of adjusting PCB and extension component FPC thereof etc.
Description of drawings
Fig. 1 is the internal structure schematic diagram according to the described rotary camera of the utility model embodiment;
Fig. 2 is according to the described structural relation schematic diagram with portable terminal of rotary camera of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing the utility model is described.
Antenna should only not design as single parts in the design of mobile terminal antenna, and pcb board and extension thereof all are the parts of antenna, and whole portable terminal should design as an antenna system.The utility model promptly by adjusting the structure of PCB and extension component thereof, is adjusted antenna performance.
Fig. 1 is the internal structure schematic diagram according to the described rotary camera of the utility model embodiment, comprise: camera FPC positioner 1, camera support 2, camera 3 (being positioned at housings), camera FPC4, camera rotating shaft 5, camera FPC inner ring 6 (referring to ringlet inside), camera FPC outer ring 7 (referring to great circle outside).
Wherein, need to stay the inner ring 6 of certain space between positioner 1 and the camera rotating shaft 5, so the space is greater than the space of camera FPC4 thickness with installation camera FPC4.Camera FPC4 is wrapped in the camera rotating shaft 5, and inner ring 6 is wrapped between positioner 1 and the camera rotating shaft 5, and outer ring 7 strides across positioner 1 and draws.
Fig. 2 is according to the described structural relation schematic diagram with portable terminal of rotary camera of the utility model embodiment.Comprise: camera FPC positioner 1, camera support 2, camera 3 (being positioned at housings), camera FPC4, camera rotating shaft 5, camera FPC inner ring 6, camera FPC outer ring 7, portable terminal mainboard 8, mobile terminal antenna 9.
Core design of the present utility model is a camera FPC positioner 1, and positioner 1 can be positioned on mobile terminal camera support 2 sidewalls, the mobile terminal case, also can extend out from portable terminal mainboard 8.The key point of design is that be positioned device 1 of camera FPC outer ring 7 supports, and inner ring 6 and outer ring 7 device that is positioned separates.Because positioner 1 has been fixed the outer ring 7 of camera FPC4, and make the inner ring 6 of camera FPC4 and outer ring 7 keep certain distance, thereby reduced the Internal and external cycle degree of coupling effectively, finally played the effect of stable portable terminal complete machine radiance.
Because the utility model adds location structure between camera FPC Internal and external cycle, fixed the FPC outer ring, and is simultaneously that Internal and external cycle is spaced apart, to reduce the Internal and external cycle degree of coupling.Make camera FPC outer ring in rotary course almost maintain static, keep certain distance between the Internal and external cycle, when satisfying spinfunction, reduced the influence of camera rotation effectively antenna performance.Experiment showed, because use the utility model, in flat board coupling test, camera rotates fluctuation that complete machine aerial radiation power is caused in 1dB, far-field pattern stability significantly improves, and it is stable that near field SAR index keeps, and every index has very big raising before.Location structure impacts for the rotation life-span of camera FPC simultaneously.
