Abstract
A USB continuous power supply device for a camera comprises a 5v mobile power source, a voltage conversion circuit and an electric energy storer. The voltage output end of the electric energy storer is connected with the camera, in this way, the voltage of the mobile power source can be converted into the service voltage required by the camera, meanwhile, the converted voltage can be stored in the electric energy storer to cope with the requirement for instantaneous high power, and therefore the requirement for long-time shooting can be satisfied. Meanwhile, even in cold weather, insulation treatment can be performed on the USB mobile power source independently, so shooting while the temperature is kept can be achieved. Accordingly, the USB power supply device for the camera is more reasonable in structure, can supply power for a long time to meet the shooting requirement, is not affected by air temperature and is wider in applicable occasion.
Description
Technical field
The present invention relates to a kind of camera peripheral hardware, refer in particular to the device can powered continuously to camera.
Background technology
As everyone knows, the service time of battery that most of camera carries is often very limited, and for the sight needing long-time capture video or photo, at this moment the battery that carries of camera is often unable to do what one wishes, and frequently changes battery and can affect use.In addition high temperature and low temperature condition also can affect the performance of camera battery, when such as winter is lower than 0 DEG C, the performance of lithium battery will decline to a great extent, and even cannot power by output current, and battery or camera can not be put in one's arms or be incubated in insulating bag and use by user.Therefore, the lasting service time of current camera lithium battery is limited, have impact on daily use; In addition, it is large by the impact of temperature, causes the applicable situation of lithium battery narrower.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of more reasonable structure, the satisfied shooting demand and not by the continuous electric supply installation of USB camera that temperature affects, its applicable situation is more extensive of powering for a long time.
In order to solve the technical problem of above-mentioned existence, the present invention adopts following technical proposals:
The continuous electric supply installation of a kind of USB camera, it includes the 5v movable power source of electrical connection, voltage conversion circuit and electric energy accumulator, and the voltage output end of described electric energy accumulator is connected with camera.
In the improvement project to the continuous electric supply installation of above-mentioned USB camera, the voltage output end of described electric energy accumulator is connected with camera by camera supplying cell prosthese.
In the improvement project to the continuous electric supply installation of above-mentioned USB camera, described electric energy accumulator is super capacitor, storage battery or rechargeable battery.
Compared with prior art, the invention has the beneficial effects as follows: because it includes the 5v movable power source of electrical connection, voltage conversion circuit and electric energy accumulator, so just movable power source can be converted to while meeting camera use voltage needs, by the voltage storage converted in electric energy accumulator with tackle moment significant power demand, thus while long-time shooting demand can be met, even if run into the weather of low temperature, we can be incubated USB portable power source separately, just can accomplish that insulation limit, limit is taken, therefore more reasonable structure of the present invention, to power for a long time satisfied shooting demand, and do not affect by temperature, its applicable situation is more extensive in addition.
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail:
[accompanying drawing explanation]
Fig. 1 is the principle schematic of the embodiment of the present invention.
[embodiment]
The present invention is the continuous electric supply installation of a kind of USB camera, and it includes the 5v movable power source 1 of electrical connection, voltage conversion circuit 2 and electric energy accumulator 3, and the voltage output end of described electric energy accumulator 3 is connected with camera 4.
The effect of voltage conversion circuit 2 is 3.7v or 7.4 by 5v changing voltage, this is because: USB portable power source provide continued power can to the equipment such as charger, mobile phone.Consider that the cell voltage that camera generally uses is a string or two series lithium batteries, its voltage is 3.7v or 7.4v, and USB supply power voltage is 5v, and for this reason, USB portable power source, by voltage conversion circuit, is supplied to camera by the applicant;
And the effect of electric energy accumulator 3 is: because camera needs big current in the moment of shooting, for this reason, by the voltage storage that converts in electric energy accumulator, to tackle the significant power demand of moment.
Through practice, use USB portable power source can greatly strengthen camera flying power, the portable power source of such as one piece of 10000mah can reach the flying power of the original-pack camera battery of 3-5 block, thus can meet and take demand for a long time; In addition, even if run into the weather of low temperature, we can be incubated USB portable power source separately, just can accomplish that insulation limit, limit is taken, thus the impact be not easy by temperature, reach by occasion object widely, therefore more reasonable structure of the present invention, satisfied shooting demand of powering for a long time, and do not affect by temperature, its applicable situation is more extensive in addition.
In order to make the connection of the voltage output end of electric energy accumulator 3 and camera 4 more convenient, simultaneously efficiently, need not make camera again and change, at this, namely the voltage output end of electric energy accumulator 3 utilizes the energising contact of battery case and shell by camera supplying cell prosthese 5() be connected with camera, so in use, camera supplying cell prosthese 5 is encased in the arranging batteries groove of camera and can be energized.
Electric energy accumulator 3 can be super capacitor, storage battery, rechargeable battery etc.
Be only preferred embodiment of the present invention in sum, be not used for limiting practical range of the present invention.Namely all equivalences done according to the content of the present patent application the scope of the claims change and modify, and all should belong to technology category of the present invention.
