Description

The DTV radio reception pen of built-in aerial

Technical field

The utility model relates to a kind of pen of writing usefulness, specifically, relates to a kind of computer DTV radio reception pen of built-in aerial.

Background technology

Chinese patent application (application number 200820213947.0, the applying date: on November 28th, 2008), submitted a " DTV radio reception pen " utility application that is used for computer to, solved the shortcoming of traditional pen function singleness to a certain extent, this DTV radio reception pen adopts external portable antenna to receive radio signals, highly sensitive, but adopt the shortcoming of external portable antenna to be, carry cumbersome, particularly when the high environment of signal strength signal intensity uses, DTV radio reception pen is a long tail, comparatively inconvenience in tow still.

The utility model content

The utility model purpose is to provide a kind of DTV radio reception pen of built-in aerial, uses external portable antenna to carry trouble, awkward shortcoming thereby improve.

For achieving the above object, solution of the present utility model is: a kind of DTV radio reception pen of built-in aerial, comprise penholder 1, penholder 2 and the DTV radio reception circuit module 3 that is installed in penholder 2 intraluminal band USB interfaces, a telescopic telescopic antenna 4 is set in penholder 2 tube chambers, telescopic antenna 4 electrically connects with DTV radio reception circuit module 3 signal input parts, and telescopic antenna 4 can elongate the tube chamber that stretches out penholder 2, and can be from the horizontal direction activity to plumbness.

Described telescopic antenna 4 is positioned at penholder 2 intraluminal ends and is provided with Universal-head 5, telescopic antenna 4 and Universal-head 5 are installed in the pore of antenna base 6, telescopic antenna 4 and Universal-head 5 can slide in the pore of antenna base 6, and antenna base 6 is fixed on the circuit board of DTV radio reception circuit module 3.

When watching DTV or listening to digital broadcasting, penholder 2 is inserted computer USB socket, pull out telescopic antenna 4 and make telescopic antenna 4 place plumbness, open the software of televising and to receive wireless digital TV-set and broadcast singal, finish using, in telescopic antenna 4 compression and back penholders 2 tube chambers, penholder 2 and penholder 1 combination can be become a pen of writing usefulness.

The beneficial effects of the utility model are, reception antenna and penholder combine together, and outward appearance is succinctly attractive in appearance, and is easy to carry, avoid long tail in tow when the high environment of signal strength signal intensity uses, and use simple.

The specific embodiment

Referring to Fig. 1; a kind of DTV radio reception pen of built-in aerial; comprise: penholder; the penholder inner hollow; be divided into the latter half penholder 1 and the first half penholder 2; penholder 1 makes up by helical structure with penholder 2 or separates; pen core is installed in the penholder 1 lower end tube chamber; penholder 2 outsides are provided with clip; the DTV radio reception circuit module 3 of band USB interface is installed in penholder 2 tube chambers; a telescopic telescopic antenna 4 is set in penholder 2 tube chambers; telescopic antenna 4 is nested together by two joints or the above metal tube of two joints and constitutes; the end that telescopic antenna 4 is installed in penholder 2 tube chambers is provided with Universal-head 5; telescopic antenna 4 and Universal-head 5 are installed in the pore of antenna base 6; telescopic antenna 4 and Universal-head 5 can slide in the pore of antenna base 6; Universal-head 5 and antenna base 6 are manufactured by metallic conductor; antenna base 6 is fixed on the circuit board of DTV radio reception circuit module 3; and be connected with DTV radio reception circuit module 3 signal input parts; thereby telescopic antenna 4 and DTV radio reception circuit module 3 signal input parts are electrically connected; telescopic antenna 4 be exposed at penholder 2 outsides an end be provided with protective cap; drawing this protective cap can make telescopic antenna 4 be elongated the tube chamber that stretches out penholder 2; telescopic antenna 4 can be from the horizontal direction activity to plumbness after pulling out under Universal-head 5 effects.Write under the state, penholder 1 and penholder 2 are combined into one, telescopic antenna 4 is compressed to be hidden in penholder 2 tube chambers, televiewing or during broadcast listening, penholder 2 is separated with penholder 1, penholder 2 is installed on the computer USB interface, pull out telescopic antenna 4 and turn to suitable position, can receive the on-air radio signal of telecommunication by telescopic antenna 4, the user mode after telescopic antenna 4 is pulled out as shown in Figure 2.

Referring to Fig. 3 and Fig. 4, Fig. 3 is the another example structure schematic diagram of the utility model, Fig. 4 is this embodiment principle of signal conversion schematic diagram, compare with the foregoing description, present embodiment is between antenna base 6 and DTV radio reception circuit module 3 signal input parts, the small-sized three end MMCX antenna sockets 7 of an inner band signal change-over switch are set, MMCX antenna socket 7 is fixed on the end of DTV radio reception circuit module 3 circuit boards away from USB interface, expose the hole of the antenna jack of MMCX antenna socket 7 correspondence from penholder 2 top cappings, referring to Fig. 4, the signal input part A of antenna socket 7 links to each other with antenna base 6, signal output part B links to each other with DTV radio reception circuit module 3 signal input parts, when not inserting external portable antenna, input A is communicated with output B under antenna socket 7 inner shell fragment elastic force effects, to DTV radio reception circuit module 3 signal input parts, this moment, telescopic antenna 4 played the effect that receives radio signals to the radio frequency signal that telescopic antenna 4 receives through input A and output B.When external portable antenna inserts antenna socket 7; external portable antenna is connected with output B by input C; the shell fragment of input A is upspring under the effect of external portable antenna plug inner core insulating protective layer and is separated with output B; the radio signal transmission that external portable antenna receives is to DTV radio reception circuit module 3 signal input parts, and this moment, external portable antenna played the effect that receives radio signals.This double-antenna structure can be brought into play two kinds of antennas advantage separately at different signal environments, has further improved receptivity of the present utility model.

In the foregoing description; when avoiding telescopic antenna 4 to be recessed in penholder 2 tube chambers and other electric elements contact short circuit; one insulation protection sleeve pipe 8 is set in penholder 2 tube chambers; shown in Fig. 3 dotted portion; telescopic antenna 4 and Universal-head 5 are installed in the insulation protection sleeve pipe 8; the internal diameter of insulation protection sleeve pipe 8 is a bit larger tham the external diameter of telescopic antenna 4 and Universal-head 5; telescopic antenna 4 and Universal-head 5 can slide in insulation protection sleeve pipe 8, thereby have guaranteed freely stretching and effectively avoiding the generation of short circuit phenomenon of built-in aerial.
