Abstract
The utility model discloses a projector capable of providing power for an intelligent television stick through an HDMI interface. According to the projector, an HDMI interface is arranged on a shell, a direct-current power supply is arranged in the shell, and among pins of the HDMI interface, inner ends of pins corresponding to a power input end of an intelligent television stick are correspondingly connected with the direct-current power supply respectively. Specifically, the inner end of the fourteenth pin of the HDMI interface is connected with the positive electrode of the direct-current power supply, and the inner end of the eighteenth pin of the HDMI interface is connected with the negative electrode of the direct-current power supply. When the intelligent television stick is used, the intelligent television stick is inserted in the HDMI interface of the projector, the projector provides power for the intelligent television stick through the fourteenth pin and the eighteenth pin of the HDMI interface, and thus the intelligent television stick can work normally without the need to plug a power supply line of an adaptor separately, thus providing convenience for users to use the intelligent television stick. The projector is especially suitable for outdoor use, and the problem that the intelligent television stick cannot be used when people forget to bring an adapter is solved.
Description
Technical field
The utility model relates to a kind of projector, and relating in particular to a kind of can be the projector of intelligent television rod power supply by the HDMI interface, belongs to projector's production field.
Background technology
The intelligent television rod is a kind of HDMI of having interface, the product of similar USB flash disk shape.Such as, use more Android intelligent television rod, be also referred to as Android TV rod, Google TV Google TV rod, Android (Android) HDMI TV rod, Android (Android) HDTV (High-Definition Television) rod etc. are the TV rods of an operation Android operating system.It is inserted on the HDMI interface of TV, and common TV has just become intelligent television (the SMART TV of similar Samsung), can see a film, surf the Net, plays games, listens to the music etc.Say that simply general mouse-keyboard is mixed in the combination of intelligent television rod and TV, just is equivalent to the Android panel computer of a large-screen.
HDMI (High Definition Multimedia Interface) is HDMI interface (English: High Definition Multimedia Interface, be called for short HDMI) be a kind of digitized video/audio interface technology, it is the tailored version digital interface that is fit to the image transmission, it can transmit audio frequency and video-audio signal simultaneously, and the maximum data transmission speed is 5Gbps.Need not simultaneously to transmit advance capable D/A or mould/number conversion at signal.The HDMI broadband digital content protection (HDCP) of can arranging in pairs or groups is suffered unwarranted copying to prevent the video content with copyright.The exceptional space that HDMI possesses can be applicable in the audio frequency and video form of upgrading in the future.And because the video of a 1080p and the audio signal demand of 8 sound channels are less than 4Gbps, so HDMI also has very big surplus.This allows it to connect DVD player respectively with a cable, receiver and PRR.
Out using will often be carried as a kind of portable display device by projector.The HDMI interface of tradition projector can not be given the power supply of intelligent television rod, and the intelligent television rod needs independent adapter power supply just can normally use.But adapter carries inconvenience when going out, and perhaps leaves behind sometimes unavoidably, and this situation can cause using the intelligent television rod, makes troubles to the user.
The utility model content
The purpose of this utility model just is that providing a kind of in order to address the above problem can be the projector of intelligent television rod power supply by the HDMI interface.
The utility model is achieved through the following technical solutions above-mentioned purpose:
Described in the utility model can be the projector of intelligent television rod power supply by the HDMI interface, and its housing is provided with the HDMI interface, is provided with DC power supply in its housing; The inner of the stitch corresponding with the power input of described intelligent television rod is connected with described DC power supply is corresponding respectively in the stitch of described HDMI interface.
Particularly, the inner of 14 stitch of described HDMI interface is connected with the positive pole of described DC power supply, and the inner of 18 stitch of described HDMI interface is connected with the negative pole of described DC power supply.
The beneficial effects of the utility model are:
When using the intelligent television rod, the intelligent television rod is plugged the HDMI interface of projector, projector is the power supply of intelligent television rod by 14,18 stitch of HDMI interface, the intelligent television rod can operate as normal, need not plug in the adapter supply lines more separately, can be user-friendly to the intelligent television rod, be particularly useful for out using, solve because leaving behind the problem that adapter causes the intelligent television rod to use.
Description of drawings
Fig. 1 be described in the utility model can be the perspective view of the projector of intelligent television rod power supply by the HDMI interface;
Fig. 2 is the enlarged drawing of the HDMI interface of projector described in the utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As depicted in figs. 1 and 2, described in the utility model can be the projector of intelligent television rod power supply by the HDMI interface, and its housing 21 is provided with HDMI interface 22, is provided with the DC power supply (not shown) in its housing 21; The stitch 23 of HDMI interface 22 comprises 1 stitch, 2 stitch, 3 stitch ... 19 stitch, wherein the inner of 14 stitch is connected with the positive pole of described DC power supply, and the inner of 18 stitch is connected with the negative pole of described DC power supply.
During use, Android intelligent television rod is inserted in the HDMI interface, the cathode power supply input of Android intelligent television rod is connected with 14 stitch, the negative power supply input of Android intelligent television rod is connected with 18 stitch, DC power supply in the housing 21 of projector directly is the power supply of Android intelligent television rod, need not power supply adaptor and can normally use Android intelligent television rod, very convenient, especially be fit to out using.
