Please refer to Fig. 3, Fig. 3 is the principle schematic according to the second preferred implementation of on-vehicle Bluetooth device of the present invention.As shown in Figure 3, the on-vehicle Bluetooth device comprises bluetooth module, operation push-button, indicator light, microphone, loud speaker, power management module, battery.
Bluetooth module be used for and and user mobile phone between carry out radio communication, complete various Bluetooth functions according to the instruction that is used for, it is built-in with Bluetooth chip, Flash chip, communication antenna, and completes above-mentioned functions by this Bluetooth chip, Flash chip, communication antenna.
Operation push-button is used for inputting various instructions for the user and comprises with the radio communication of cell phone apparatus, to the various instructions of the charging of cell phone apparatus and other electronic equipments; Indicator light is used for passing on different information to the user, and it mainly by the lighting, extinguish and show that different colors passes on indicator light from various information to the user, makes the user make different commands to the on-vehicle Bluetooth device according to its above-mentioned information that provides.
Microphone and loud speaker are used for completing user and the on-vehicle Bluetooth device carries out information interaction, and carry out information interaction by on-vehicle Bluetooth device and cell phone apparatus and other equipment.Wherein, microphone is used for sound import and is transferred to cell phone apparatus by bluetooth module, and loud speaker is used for cell phone apparatus the opposing party's conversation sound and other sound that send thereof are externally exported, and passes to the user.
Battery is used to the power supply of on-vehicle Bluetooth device, and to the electronic equipment charging that is connected with the on-vehicle Bluetooth device.
Power management module is used for externally the discharge management and to the power supply management of other chips on circuit of Charge Management, battery to battery.
The on-vehicle Bluetooth device can carry out hand-free call by bluetooth module and cell phone apparatus, is that the electronic equipment charging connects to complete by data wire with electronic equipment by the connecting interface of being located on the on-vehicle Bluetooth device; During connection, except to electronic equipment charges, also can carry out file transfer and information sharing between on-vehicle Bluetooth device and electronic equipment; And wired connection can and not have between the electronic equipment of Bluetooth function at the on-vehicle Bluetooth device yet and carries out file transfer and information interaction, and this is that blue tooth wireless technology can not be accomplished.
Please refer to Fig. 4, Fig. 4 is the schematic diagram of the connecting interface of execution mode shown in Figure 3.As shown in Figure 4, connecting interface is 3 usb 1s, 2,3, due to USB interface versatility widely, this connecting interface can with more equipment connection.
3 usb 1s, 2,3 are USB 2.0 interfaces, USB 2.0 interfaces are the standard usb interface of generally using now, so adopting, this interface meets USB 2.0 interfaces of USB 2.0 standards as connecting interface, the scope that can use can be enlarged to greatest extent, maximum electronic equipments can be connected.
As required, for obtaining file transfer speed faster, this usb 1,2,3 also can adopt USB 3.0 interfaces that meet USB 3.0 standards, USB 3.0 interfaces are as interface standard of future generation, it is compared present USB 2.0 interfaces and has huge progress, its file transfer speed is faster, and the efficient that data are processed is higher, also can make main frame for during more power is provided.With regard to present embodiment, adopting the benefit of USB 3.0 interface maximums is that file transfer speed is faster, and to use USB 3.0 interface connecting electronic equipment be that the efficient of its charging is faster, and the required time is shorter.
3 usb 1s, 2,3 have different output voltages, are respectively 2.5V-3.5V, 3.5V-4.5V, and 4.5V-6V is used for charging to various different types of electronic equipments.
According to the needs of reality charging, above-mentioned 3 usb 1s, 2,3 output voltage can also be arranged to other numerical value.Such as, according to the actual needs of charging, above-mentioned 3 usb 1s, 2,3 output voltage are made as 1V-3V, 3V-6V, 6V-15V etc.
