Abstract
The utility model relates to a two-in-one antenna for vehicles, which at least comprises a casing, a CMMB (China Mobile Multimedia Broadcasting) antenna and a radio antenna, wherein the CMMB antenna and the radio antenna are arranged in the casing. Two antennas in different frequency ranges are arranged in a limited space, the interior space of the casing can be sufficiently used, and effect of receiving of double signals can be realized, so that manufacturing cost is reduced, overall appearance and practical value are improved.
Description
Technical field
The utility model relates to a kind of automobile-used two-in-one antenna, relate to particularly that a kind of (China Mobile Multimedia Broadcasting, CMMB) antenna and a radio (radio) antenna are integrated in the automobile-used two-in-one antenna in the housing simultaneously with a China Mobile multimedia broadcasting.
Background technology
(China Mobile Multimedia Broadcasting, CMMB) antenna and radio (radio) antenna is all antenna common on the general automobile to China Mobile multimedia broadcasting.It was delivered in 2006 CMMB for Chinese own action television standard.CMMB is based on (StiMi) transmission technology of Chinese independent research " the interactive many service infrastructure devices in satellite and ground ".Operating frequency, the 25MHz frequency range of 2.6GHz used in this service, and 25 television videos and 30 station channels can be provided, and some data channels.STiMi supports S frequency band and UHF/VHF frequency band, and will use satellite and ground broadcast relay system simultaneously, to cover.This technology also has some similitude with the European DVB-SH specification that is used in satellite and hand-held service.
On the other hand, radio for being widely used in the mechanics of communication on the car very much, and almost each automobile all has installation.By radio signal, the user can listen to AM and/or FM broadcast program, also can utilize radio signal to converse, and therefore has multiple function.
Yet in the prior art, CMMB antenna and wireless aerial are all indivedual independently being installed on the automobile, not only need to take more installing space, because two kinds of antennas are all manufacturedly respectively, therefore make manufacturing cost higher again.
In view of this, must propose a kind of car antenna of improvement, CMMB antenna and radio antenna can be integrated, reducing volume and to take up room, and can reduce manufacturing cost, to promote practical value.
The utility model content
Main purpose of the present utility model provides a kind of automobile-used two-in-one antenna, technical problem to be solved be with a CMMB antenna and a radio aerial integration in a housing, and then reduce volume and take up room, and can reduce manufacturing cost, to promote practical value.
The purpose of this utility model and solve its technical problem and realize by the following technical solutions.According to a kind of automobile-used two-in-one antenna that the utility model proposes, it comprises at least: a housing; One China Mobile multimedia broadcasting (China Mobile Multimedia Broadcasting, CMMB) antenna is arranged in this housing; And a radio (radio) antenna, be arranged in the housing.
By technique scheme, the utility model has following advantage at least:
The utility model by with CMMB antenna and radio aerial integration in a housing, and then reduce volume and take up room, and can reduce manufacturing cost, promote practical value.
The utility model by with CMMB antenna and radio aerial integration in a housing, with the effect that realizes that dual signal receives.
The utility model with CMMB antenna and radio aerial integration in a fin-shaped housing, thereby increase overall appearance, and have preferable antenna protection effect.
Since the utility model with CMMB antenna and radio aerial integration behind a fin-shaped housing, the voltage of the antenna of these two kinds of frequency ranges can not interfere with each other, and therefore the utlity model has good signal reception.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.

Embodiment
For further setting forth the utility model is to reach technological means and the effect that predetermined utility model purpose is taked, below in conjunction with accompanying drawing and preferred embodiment, to embodiment of the present utility model describe in detail as after.
Please refer to as shown in Figure 1, is the cross-section illustration of the automobile-used two-in-one antenna of this preferred embodiment of the utility model.As shown in the figure, this automobile-used two-in-one antenna 1 comprises a housing 100, a China Mobile multimedia broadcasting (China Mobile Multimedia Broadcasting, CMMB) antenna 110 and a radio (radio) antenna 120.Wherein, this CMMB antenna 110 and this radio antenna 120 all are arranged in this housing 100.In addition, this radio antenna 120 is a kind of AM/FM antennas.
In the utility model preferred embodiment, this housing 100 is a kind of fin-shaped housings, and that its advantage includes is handsome in appearance, length is short, windage is less and the antenna protection effect is preferable.This housing 100 is made up of a base 101 and a protective cover 102, and this base 101 and this protective cover 102 are to pay modes and interosculate with screw 103 locks.Yet when practical application, base 101 more can engage mode or welding manner with protective cover 102 and interosculate, and therefore has bigger manufacturing elasticity.In addition; CMMB antenna 110 is fixed on the base 101, and radio antenna 120 is fixed in this protective cover 102 inner surfaces, and protective cover 102 combines with base 101 again; CMMB antenna 110 and radio antenna 120 are covered in the inside of this housing 100, reach the effect of protection.
Moreover, equally as shown in Figure 1, CMMB antenna 110 and this radio antenna 120 are and a printed circuit board (PCB) assembly (Printed Circuit Board Assembly, PCBA) 130 combinations, this PCBA 130 can be in order to integrating this two kinds of aerial signals, and carry out the transmission of signal.
Signal the above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art, in not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
