Abstract
The utility model discloses a vehicle-mounted computer charging device comprising a first inverter, an additional power supply unit, a second inverter, a control unit and a charging interface, wherein the first inverter is connected to the additional power supply unit, the additional power supply unit is connected to the second inverter, the second inverter and the first inverter are connected to the charging interface, and the control unit is respectively connected with and controls the additional power supply unit and the second inverter. By adopting the vehicle-mounted computer charging device, power output can still be provided for a vehicle-mounted computer and other vehicle-mounted equipment without influencing the startup ignition function of a vehicle when the vehicle flames out.
Description
Technical field
The utility model relates to a kind of charging device, particularly a kind of vehicle-mounted computer charging device.
Background technology
Vehicle-mounted computer is a kind of motor multimedia entertainment information center of Highgrade integration, at present, on some high-end automobiles configuration is arranged all.
Yet, vehicle-mounted computer in the market all is that the engine with automobile is a power supply, after automobile has stopped for a long time so, the electric weight of the storage battery in the automobile will descend, thereby influence the automotive ignition function, and, when engine start, can produce big electric current, thereby disturb the operate as normal of vehicle-mounted computer.
The utility model content
The utility model purpose is: propose a kind of vehicle-mounted computer charging device, it can effectively solve above-mentioned technical problem.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of vehicle-mounted computer charging device, described charging device comprise first inverter, extra power supply unit, second inverter, control unit and charging inlet; Described first inverter is connected to described extra power supply unit, described extra power supply unit is connected to described second inverter, described second inverter and described first inverter all are connected to described charging inlet, and described control unit connects respectively and controls described extra power supply unit and described second inverter.
As preferred version, described charging inlet comprises 5 expansion interfaces, is respectively vehicle-mounted computer display charging inlet, vehicle-mounted computer main frame charging inlet, external computer power supply interface and 2 standard USB interface.
As preferred version, described charging device also is provided with a protective circuit, and described first inverter and described second inverter are connected to described protective circuit earlier, and described protective circuit is connected to described charging inlet again.
As preferred version, be provided with a testing circuit between described charging inlet and the described control unit, be used to detect the required output voltage of charging port, thereby provide suitable voltage to load.
The beneficial effects of the utility model are: adopt the utility model still to provide power supply output to vehicle-mounted computer and other mobile units, and can not influence the startup sparking function of automobile when automobile flameout.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model another embodiment structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1: a kind of vehicle-mounted computer charging device, described charging device comprise first inverter 1, extra power supply unit 2, second inverter 3, control unit 5 and charging inlet 4; Described first inverter 1 is connected to described extra power supply unit 2, described extra power supply unit 2 is connected to described second inverter 3, described second inverter 3 all is connected to described charging inlet 4 with described first inverter 1, and described control unit 5 connects respectively and controls described extra power supply unit 2 and described second inverter 3.
Another embodiment of the present utility model, as shown in Figure 2, it mainly is that a protective circuit 6 is set,, described first inverter 1 and described second inverter 3 are connected to described protective circuit 6 earlier, and described protective circuit 6 is connected to described charging inlet 4 again; And between described charging inlet 4 and described control unit 5, be provided with a testing circuit 7, be used to detect the required output voltage of charging port, thereby provide suitable voltage to load.
More than show principal character and the innovative point of only having described this programme.Those skilled in the art should understand, and this programme is not restricted to the described embodiments.Under the prerequisite that does not break away from the innovation point and protection range, this programme also has various variations, and these changes and improvements all will fall in the claimed scope of this programme.The claimed scope of this programme is limited by appending claims and equivalent thereof.
