Compared with the prior art, the utility model discloses carPlay formula HUB chip can make all extension USB interface compatibility carplay, and it is more convenient to use, owing to there is power control chip's existence, can provide the electric energy for all extension USB interfaces simultaneously, strengthens its charging capability.
Description
Technical field
The utility model relates to a kind of auto parts machinery, especially relates to one and can realize CarPlay and large electric current simultaneouslyThe vehicle-mounted usb hub of charging.
Background technology
Through development for many years, the application scenarios of USB standard is more and more wider, original automobile USB quantitySeem awkward, therefore increasing automobile starts to configure USBHUB, for example Chinese patent CN204331720U discloses one vehicle-mounted USB multimedia equipment (USBHUB) cheaply, comprises housingWith the pcb board being located in housing, pcb board is provided with power input component, USB connector, Hub chipWith USB charging assembly, Hub chip is connected with USB connector, and USB charging assembly connects respectively power supplyInput module and Hub chip.
But the disclosed USBHUB of above-mentioned Chinese patent can only realize simple USB read-write capability, does not prop upHold carplay and connect and USB quick charge technology, at present, the CarPlay of Apple because of its can with IOSEquipment seamless link, has good user and experiences, but at present but or can not use, or after application, vapourCar just can not connect other USB devices.
Utility model content
The purpose of this utility model is exactly to provide the one can be in order to overcome the defect that above-mentioned prior art exists simultaneouslyRealize the vehicle-mounted usb hub of CarPlay and large current charge.
The purpose of this utility model can be achieved through the following technical solutions:
The vehicle-mounted usb hub that can simultaneously realize CarPlay and large current charge, comprising:
Power supply control chip, is connected with vehicle power and vehicle-mounted USB interface respectively;
Also comprise:
CarPlay formula HUB chip, is connected with power supply control chip and vehicle-mounted USB interface respectively;
Expanding USB interface, is at least provided with two, respectively with power supply control chip and CarPlay formula HUB chipConnect.
Described expanding USB interface is provided with three altogether.
Described hub also comprises the on-off circuit that is used to expanding USB interface that charge protection is provided, this switch electricityRoad is located between expanding USB interface and power supply control chip.
Described hub also comprises 8 path connectors, this 8 path connector be located at vehicle power and power supply control chip itBetween.
In all expanding USB interface, has one at least for USBMini-B interface.
Compared with prior art, the utlity model has following advantage:
1) CarPlay formula HUB chip, can make the compatible Carplay of all expanding USB interface, uses moreAdd conveniently, simultaneously owing to there being the existence of power supply control chip, can provide electric energy for all expanding USB interface,Strengthen its charging ability.
2) on-off circuit can play the effect of current limliting, specifically has that high temperature alarm reports and charging enables and chargesCurrent-limiting function, has improved its security.
3) 8 path connectors can provide extra expansion, make wiring more clear, more convenient.
4) have one at least for USBMini-B interface, consistent with the form of original vehicle-mounted USB interface, noDestroy on original car body and design.
