Embodiment
The utility model embodiment aims to provide a kind of radio universal serial line interface modulator-demodulator, can have less complete machine size.
Below in conjunction with accompanying drawing the utility model embodiment is described in detail.
As shown in Figure 2, present embodiment radio universal serial line interface modulator-demodulator 6, comprise modulator-demodulator body 61, has printed circuit board (PCB) in the modulator-demodulator body, described printed circuit board (PCB) one end is electrically connected with USB (universal serial bus) 62, the other end is electrically connected with antenna, the signal that therefore described antenna receives can pass to access terminals equipment by described USB (universal serial bus), described antenna is located on the antenna holder 63, antenna holder 63 is articulated in the outside of modulator-demodulator body 61, therefore antenna holder 63 can 64 rotations be opened with realization or close up around the articulated section, after antenna holder 63 was opened, the antenna on it can received signal, as shown in Figure 3, after antenna holder 63 closes up, can abut on the body 61 of modulator-demodulator, at this moment, antenna holder 63 and modulator-demodulator body 61 are side-by-side, make that the complete machine size of described radio universal serial line interface modulator-demodulator is shorter, reached the purpose of dwindling its complete machine size.
Described antenna comprises main antenna and slave antenna, main antenna is born the main task of received signal, when main antenna because fault or other reasons and can't operate as normal the time, slave antenna can be born the main task of received signal temporarily, corresponding with it, antenna holder 63 comprises main antenna support 631 and slave antenna support 632, and described main antenna is arranged on the main antenna support 631, and described slave antenna is arranged on the slave antenna support 632.
By Fig. 2 and Fig. 3 as can be known, the Cross-section Design of main antenna support 631 and slave antenna support 632 is become the U type, and the left and right sides that makes the two be articulated in modulator-demodulator body 61 relatively, antenna can be held with bigger receiving area.
When not using radio universal serial line interface modulator-demodulator 6, enter dust easily in its USB (universal serial bus) 62, generally all use a cap to cover USB (universal serial bus) 62, and in the present embodiment, can make the length of main antenna support 631 and slave antenna support 632, suitable with the length sum of modulator-demodulator body 61 and USB (universal serial bus) 62, and main antenna support 631 and slave antenna support 632 are made as blind end away from the end 633 of articulated section 64, after closing up, main antenna support 631 and slave antenna support 632 encase modulator-demodulator body 61 and USB (universal serial bus) 62, at this moment, the cap that main antenna support 631 and slave antenna support 632 can be used as USB (universal serial bus) 62 uses, not only saved the trouble of USB (universal serial bus) 62 caps has been set separately, and made that radio universal serial line interface modulator-demodulator 6 overall structures are simpler.
But in said structure, after opening main antenna support 631 and slave antenna support 632, the overall dimensions of radio universal serial line interface modulator-demodulator 6 is bigger, taken bigger space, for the size after limiting it and opening, as shown in Figure 3 and Figure 4, can make the length of the length of main antenna support 631 and slave antenna support 632 less than modulator-demodulator body 61, abut in the left and right sides of modulator-demodulator body 61 after main antenna support 631 and slave antenna support 632 close up, such structure can make radio universal serial line interface modulator-demodulator 6 be tending towards miniaturization more.
Generally speaking, can be by manually breaking main antenna support 631 and slave antenna support 632 into two with one's hands, but consideration for convenience, the opener of being convenient to open main antenna support 631 and slave antenna support 632 can also be set on radio universal serial line interface modulator-demodulator 6, for example: draw-in groove 6311 is set on main antenna support 631, the buckle 6321 that matches with draw-in groove 6311 is set on slave antenna support 632, and on the medial surface of main antenna support 631 and slave antenna support 632, be oppositely arranged the magnet that repels each other to 634, after buckle 6321 breaks away from draw-in groove 6311 under external force, repel each other magnet to 634 promote main antenna supports 631 and slave antenna support 632 around the articulated section 64 rotating opening with away from the other side; And when closing up main antenna support 631 and slave antenna support 632 under external force, draw-in groove 6311 and buckle 6321 snap together, and make main antenna support 631 and slave antenna support 632 can not open 634 effects because of the magnet that repels each other.
Because the antenna that is arranged on main antenna support 631 and the slave antenna support 632 is used for received signal, the magnet that repels each other might produce signal 634 and disturb, and for this purpose, can use elastic component such as spring to replace repelling each other magnet to 634.
Break away from draw-in groove 6311 under external force for ease of buckle 6321, button 6312 is set on draw-in groove 6311, pressing the button 6312 makes draw-in groove 6311 downward-sloping, buckle 6321 just can break away from the constraint of draw-in groove 6311 gradually, and the magnet that repels each other to 634 effect under mutually away from, finally open main antenna support 631 and slave antenna support 632.
In the above-described embodiments, the complex structure of main antenna support 631 and slave antenna support 632, manufacture difficulty is higher, as shown in Figure 6, angle from simplified structure, reduction manufacture difficulty, main antenna support 631 and slave antenna support 632 can also be designed to template, and make the two be articulated in the both sides up and down of modulator-demodulator body 6.
For making said structure compact more, the length of main antenna support 631 and slave antenna support 632 can also be made as suitable with the length sum of modulator-demodulator body 61 and USB (universal serial bus) 62, and use a junction 65 that main antenna support 631 and slave antenna support 632 end away from articulated section 64 is coupled together, thereby make main antenna support 631 and slave antenna support 632 form one.
The above; it only is embodiment of the present utility model; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; can expect easily changing or replacing, all should be encompassed within the protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the described protection range of claim.
