Description

One carries battery powered Portable projector
Technical field
This utility model relates to one and carries battery powered Portable projector.
Background technology
Existing scialyscope be all need to be accessed power supply after just can use, its use process be unable to do without power supply, Make cannot use in some places not having power supply;And in some distance socket remote positions, then need to use insert row Transferring, this must cause complex circuit, is not convenient to use.
Summary of the invention
The technical problems to be solved in the utility model, is to provide one to carry battery powered Portable projector, just Use in user.
This utility model is achieved in that one carries battery powered Portable projector, including projector body, It is provided with LED and projector circuit board in described projector body, also includes that battery module, described battery module are located at described In projector body, described battery module includes set of cells, cell balancing circuit, battery pack protective circuit, control circuit, output Module one and output module two;Described set of cells is connected to described battery pack protective circuit by described cell balancing circuit, Described control circuit connects described battery pack protective circuit, output module one and output module two respectively;Described set of cells is protected Protection circuit is connected to described output module one and output module two;Described output module two is connected to LED, described output mould Block one is connected to described projector circuit board.
Further, also including battery charger and charged state identification circuit, described charging circuit connects respectively To described battery pack protective circuit and charged state identification circuit, described charged state identification circuit connects described control respectively Circuit, output module one and output module two.
The utility model has the advantage of: this utility model one carries battery powered Portable projector, it is simple to use Family is carried, and can outdoor or power free in the case of use.
Accompanying drawing explanation
This utility model is further described the most in conjunction with the embodiments.
Fig. 1 is that this utility model one carries battery module schematic diagram in battery powered Portable projector.
Detailed description of the invention
Referring to shown in Fig. 1, this utility model carries battery powered Portable projector, including projector body, institute It is provided with LED and projector circuit board in stating projector body, also includes that battery module, described battery module are located at described throwing Shadow machine is the most internal, and described battery module includes set of cells, cell balancing circuit, battery pack protective circuit, control circuit, output mould Block one and output module two;Described set of cells is connected to described battery pack protective circuit, institute by described cell balancing circuit State control circuit and connect described battery pack protective circuit, output module one and output module two respectively;Described battery pack protection Circuit is connected to described output module one and output module two;Described output module two is connected to LED, described output module One is connected to described projector circuit board;Wherein set of cells is Li-ion batteries piles.
This utility model carries battery powered Portable projector and also includes that battery charger and charged state are known Other circuit, described charging circuit is respectively connecting to described battery pack protective circuit and charged state identification circuit, described charging State identification circuit connects described control circuit, output module one and output module two respectively.
Output module one exports 16.5V voltage and 3A electric current, powers to projector circuit board;Output module two exports 16.5V voltage and 6A electric current, power to LED.
In use, when battery module is directly connected to power supply, can be projector circuit board by battery charger And LED directly provides power supply;And it is charged for set of cells;When there is no external power supply, then direct by set of cells Power supply is provided for projector circuit board and LED.
Although the foregoing describing detailed description of the invention of the present utility model, but those familiar with the art should Working as understanding, our described specific embodiment is merely exemplary rather than for the limit to scope of the present utility model Fixed, those of ordinary skill in the art, in the equivalent modification made according to spirit of the present utility model and change, should Contain in scope of the claimed protection of the present utility model.
