Compared with the prior art, the high-voltage electrical box with the contactor fault diagnosis modules has the advantages of high safety and the like.
Description
Technical field
The utility model relates to a kind of high-voltage electric box, especially relates to a kind of high-voltage electric box with the contactless switch fault diagnosis module.
Background technology
The consciousness of Along with people's environmental protection at present strengthens and oil resources in short supply day by day day by day; The public also grows with each passing day to pure understanding and demand electronic and hybrid vehicle, and car load factory and auto parts and components manufacturer nearly all under this background all develop pure electric vehicle and hybrid vehicle as strategic emphasis.As the electrokinetic cell high-voltage electric box (BDU) of one of requisite parts in pure electric automobile and the hybrid vehicle, be the vitals that is related to car load safety.All there is exploitation electrokinetic cell high-voltage electric box in present numerous parts producer; But its function just realizes the connection in electrical source of power loop through high voltage connector and wire fuse; And the state of high voltage connector is not detected, this is with being a great potential safety hazard.
The utility model content
The purpose of the utility model is exactly the high-voltage electric box that a kind of safe band contactless switch fault diagnosis module is provided in order to overcome the defective that above-mentioned prior art exists.
The purpose of the utility model can realize through following technical scheme:
A kind of high-voltage electric box with the contactless switch fault diagnosis module; Comprise power brick, main contactor, preliminary filling contactless switch, negative pole contactless switch, diverter, load and contactor control circuit; Described main contactor and the parallel connection of preliminary filling contactless switch; Described main contactor one end is connected with power brick is anodal, and described power brick negative pole, negative pole contactless switch, diverter are connected with load successively, and the described main contactor other end is connected with load; It is characterized in that; Also comprise anodal contactless switch diagnostic module and negative pole contactless switch diagnostic module, described anodal contactless switch diagnostic module is connected between main contactor and the load, and described negative pole contactless switch diagnostic module is connected between diverter and the load.
Described anodal contactless switch diagnostic module and negative pole contactless switch diagnostic module include bonded assembly voltage conversion circuit, high/low-voltage isolation circuit, analog-to-digital conversion module and controller successively.
Compared with prior art, the utlity model has following advantage:
1, on the basis of conventional high-tension electrical box, increased a contactless switch fault diagnosis module, made systemic-function improve greatly, can realize the state of both positive and negative polarity contactless switch in the pure electronic and hybrid vehicle is detected.
2, before the normal operation of car load, can judge that whether contactless switch has fault, can in time overhaul if any fault; Avoid causing serious accident.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.

As shown in Figure 1; A kind of high-voltage electric box with the contactless switch fault diagnosis module; Comprise power brick 1, main contactor 2, preliminary filling contactless switch 3, negative pole contactless switch 4, diverter 5, load 6, contactor control circuit 7, anodal contactless switch diagnostic module 8 and negative pole contactless switch diagnostic module 9; Described main contactor 2 and 3 parallel connections of preliminary filling contactless switch, described main contactor 2 one ends and 1 anodal connection of power brick, described power brick 1 negative pole, negative pole contactless switch 4, diverter 5 are connected with load 6 successively; Described main contactor 2 other ends are connected with load 6; Comprise that also described anodal contactless switch diagnostic module 8 is connected between main contactor 2 and the load 6, described negative pole contactless switch diagnostic module 9 is connected between diverter 5 and the load 6.Described anodal contactless switch diagnostic module 8 includes bonded assembly voltage conversion circuit, high/low-voltage isolation circuit, analog-to-digital conversion module and controller successively with negative pole contactless switch diagnostic module 9.
Workflow:
Whether 1) the negative pole contactless switch is detected through negative pole contactless switch diagnostic module 8 in the start back has unusually, if any sending warning signal through bus unusually, the request maintenance.
Whether have unusually, if any sending warning signal through bus unusually, the request maintenance through anodal contactless switch diagnostic module 9 if 2) detecting anodal contactless switch.
3) like above-mentioned equal trouble free, car load normally moves.
