[ description of the drawings ]
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained without inventive work, wherein:
fig. 1 is the utility model provides an OBD power supply unit's schematic structure diagram.
[ detailed description ] embodiments
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides an OBD power supply apparatus 100 for connecting an OBD interface of an automobile to supply power to an on-board intelligent device. The OBD power supply device 100 comprises an OBD connector 10, a switch 30, a transformer 50, a smart device connector 70 and a data connection line, wherein the OBD connector 10, the switch 30, the transformer 50 and the smart device connector 70 are sequentially connected through a wire.
Wherein OBD is the abbreviation of On-Board Diagnostic in English, and Chinese translates into "vehicle diagnosis system". The vehicle-mounted diagnosis system monitors the running state of the engine and the working state of the tail gas aftertreatment system at any time, and immediately sends out a warning once the condition that the emission possibly exceeds the standard is found. The OBD signal is a signal sent by the vehicle-mounted diagnosis system and can be a control signal or a monitoring signal.
OBD connects 10 and the OBD interface connection of car for pass through the storage battery of OBD interface connection car to get the electricity from the storage battery.
The transformer 50 is used for boosting or reducing the voltage of the battery, so that the rated voltage suitable for the vehicle-mounted intelligent equipment is achieved. Specifically, in this embodiment, the vehicle-mounted intelligent device is a vehicle event data recorder, and of course, in other embodiments, the vehicle-mounted intelligent device may be an intelligent device suitable for automobiles, such as a navigator, a vehicle-mounted dust collector, a vehicle-mounted burglar alarm, and the like.
The transformer 50 is a step-down transformer, so that the voltage of the storage battery is reduced to the rated voltage of the automobile data recorder, the normal work of the automobile data recorder is guaranteed, and the stability and the reliability of the OBD power supply device are improved.
Simultaneously, because the electricity that the OBD interface of car provided is the normal electricity, adopts OBD power supply unit 100 does the power supply of on-vehicle intelligent equipment makes on-vehicle intelligent equipment is in the power supply state for a long time, and the time has been of a specified duration and has caused car storage battery insufficient voltage easily. Therefore, the switch 30 is disposed between the transformer 50 and the OBD connector, and when the vehicle-mounted smart device is not required to be used, the driver can cut off the circuit through the switch 30.
The number of the intelligent device connectors 70 is multiple, and the intelligent device connectors 70 are respectively used for supplying power to different vehicle-mounted intelligent devices. Preferably, the smart device connector 70 is a USB connector, a Type-C connector, a Lightning connector, or the like.
Through setting up the different grade type the smart machine connects 70 for OBD power supply unit 100 can be for the on-vehicle smart machine power supply of a plurality of differences simultaneously, can charge for cell-phone, panel computer even.
The data connecting line is used for guiding diagnostic fault codes originally stored in an automobile OBD system into the vehicle-mounted intelligent equipment for storage. Therefore, maintenance personnel can check the diagnosis fault codes through the vehicle-mounted intelligent equipment without connecting wires additionally to the automobile OBD system, and the automobile problems are conveniently checked and diagnosed.
Compared with the prior art, the OBD power supply device 100 of the present invention, by providing the OBD connector 10 and the transformer 50, enables the vehicle-mounted intelligent device to take electricity through the OBD interface in the vehicle, and has the advantages of convenient installation and stronger stability and reliability compared with the prior art of taking electricity from a vehicle fuse box or a cigarette lighter; by arranging the switch 30 between the transformer 50 and the OBD connector 10, when the automobile is turned off and the automobile data recorder is not needed to be used, the power can be cut off through the switch 30; set up and connect OBD connects 10 with smart machine connects 70 the data link for the diagnostic trouble code of originally saving in car OBD system can be leading-in on-vehicle smart machine stores, has made things convenient for the investigation and the diagnosis of car problem.
The above embodiments of the present invention are only described, and it should be noted that, for those skilled in the art, modifications can be made without departing from the inventive concept, but these all fall into the protection scope of the present invention.
