Description
Technical field
The utility model relates to a kind of bluetooth serial ports adapter with power supply.
Background technology
The bluetooth serial ports adapter can make the peripherals of the band serial ports with wireless transmission function realize wireless transmission, integrated wireless transport module again in the peripherals of band serial ports, thereby greatly reduce the cost of the peripherals of band serial ports, therefore the bluetooth serial ports adapter has also obtained widespread use.Existing bluetooth serial ports adapter has just played the effect that a serial ports changes bluetooth, function singleness, its inside battery unit also just be the bluetooth module in the bluetooth serial ports adapter and one-chip computer module power supply, can't be to various peripherals power supplies.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of with bluetooth serial ports adapter power supply, one-object-many-purposes.
The technical solution of the utility model is achieved in that a kind of bluetooth serial ports adapter with power supply, comprise that a RS232 changes data conversion module and a housing of bluetooth, described data conversion module is electrically connected to a battery unit by a switch and a power supply processing circuit, also is electrically connected with respectively through voltage boosting and stabilizing circuit and the mobile phone type USB power supply plug of drawing from housing and power supply plug or the socket of drawing through decompression voltage regulator and from housing from described battery unit.
Described power supply processing circuit is described voltage boosting and stabilizing circuit or described decompression voltage regulator, and described switch is on/off and voltage-selected switch.
Described battery unit is a rechargeable battery, described rechargeable battery is electrically connected to the mobile phone type USB charging socket that is fixed on the adapter housing by a charge power supply administration module, and described mobile phone type USB charging socket and described mobile phone type USB power supply plug are all mini or are all miniature.
Status indicator lamp also is installed on the housing of described bluetooth serial ports adapter.
Useful technique effect of the present utility model is as follows: described battery unit is electrically connected with through voltage boosting and stabilizing circuit and from the mobile phone type USB power supply plug that housing is drawn, can carries out emergent charging to the mobile phone of respective model, one-object-many-purposes and easy to carry; Described rechargeable battery electrically connects type USB charging socket on the other hand by a charge power supply administration module, the charger for mobile phone of this mobile phone type USB charging socket and respective model is complementary, the available handsets charger charges to rechargeable battery, need not be equipped with mains charger for the bluetooth serial ports adapter separately again; Described battery unit is electrically connected with through decompression voltage regulator and power supply plug or the socket of drawing from housing, can and reduce its cost to various mobile phone peripherals power supplies such as sensor.
Description of drawings
Fig. 1 is the principle of work block diagram of the bluetooth serial ports adapter of band power supply in the utility model.
Embodiment
Below in conjunction with accompanying drawing, be described further by the utility model of embodiment.
As shown in Figure 1: a kind of bluetooth serial ports adapter with power supply, comprise that a RS232 changes data conversion module 1 and a housing of bluetooth, data conversion module links to each other with the rechargeable battery 5 of a 3.7V through a voltage boosting and stabilizing circuit 3 or decompression voltage regulator 4 by a single-pole triple-throw (SPTT) switch 2, simultaneously, also draw type USB power supply plug 6 on the other hand through housing from the voltage boosting and stabilizing circuit output terminal, this mobile phone type USB power supply plug is mini, this voltage boosting and stabilizing circuit is exported the 5V operating voltage by its inner 5V voltage stabilizing chip, can carry out emergent charging to the mobile phone that mini mobile phone type USB socket is installed; On the other hand, draw a single core power supply base 7 from the decompression voltage regulator output terminal through housing, this decompression voltage regulator is exported the 3.3V operating voltage by its inner 3.3V voltage stabilizing chip, can be to peripherals such as the sensor power supply that is complementary with single core power supply base; Rechargeable battery links to each other with mobile phone type USB charging socket 9 on being fixed in bluetooth serial ports adapter housing by a charge power supply administration module 8, this mobile phone type USB charging socket also is mini, and rechargeable battery can charge by using the charger for mobile phone that is complementary with mini mobile phone type USB socket like this; The bluetooth state pilot lamp 10 of indication bluetooth duty is installed on the housing of bluetooth serial ports adapter, described bluetooth state pilot lamp links to each other with data conversion module, comes the designation data modular converter whether carrying out wireless transmission by the bluetooth state pilot lamp being arranged different colors; Whether indicator of the power supply status 11 also is installed on the housing of bluetooth serial ports adapter, and indicator of the power supply status links to each other with the charge power supply administration module, indicate rechargeable battery to be full of by indicator of the power supply status being arranged different colors; We can select high voltage or low-voltage to come to power to data conversion module according to the distance of Bluetooth signal transmitting range, when transmitting range is far away, the single-pole triple-throw (SPTT) switch is switched to contact 21 select high voltage, when transmitting range is near, the single-pole triple-throw (SPTT) switch is switched to contact 23 select low-voltage, when data conversion module is not worked, the single-pole triple-throw (SPTT) switch is switched to contact 22, save electric energy.
