The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
The circuit principle structure schematic diagram that Fig. 1 is a kind of embodiment of the present utility model;
The circuit principle structure schematic diagram that Fig. 2 is another kind of embodiment of the present utility model;
The circuit principle structure schematic diagram that Fig. 3 is another embodiment of the present utility model.
The specific embodiment
With reference to accompanying drawing, elec. vehicle high-voltage interlocking system of the present utility model comprises high tension supply 1, the high-tension current transmission line be connected with high tension supply 1 be connected to the high-tension current transmission line on and connector 3 for being connected high pressure consumer 2, native system also comprises low pressure controller 4 and the low-voltage supply line be connected with low pressure controller 4, be in series with the indicator lamp corresponding with high pressure consumer 25 on this low-voltage supply line, the primary and secondary plug be provided with in connector 3 by connector 3 touches and is connected in parallel on the short circuiting switch 6 on low-voltage supply line with indicator lamp 5, be connected with the contactless switch corresponding with high pressure consumer 27 on the high-tension current transmission line, the coil power supply end of contactless switch 7 is electrically connected to low pressure controller 4.Wherein, short circuiting switch 6 is touched by the primary and secondary plug of connector 3, can be understood as connector the primary and secondary plug grafting or pull away corresponding closure or the off-state of controlling short circuiting switches of two states.When closed as for the primary and secondary plug when Connector Clip 3, short circuiting switch is to disconnect or closure, can be arranged according to actual needs.The primary and secondary plug of the Connector Clip 3 shown in accompanying drawing is all in pulling away state, and the short circuiting switch 6 under this state disconnects.Contrary, when the primary and secondary plug of Connector Clip 3 during all in inserting state, short circuiting switch 6 closures, the indicator lamp 5 corresponding with short circuiting switch 6 is by short circuit.
In the utility model, contactless switch 7 adopts the solenoid type contactless switch, and the main switch in it is for controlling the break-make of high-tension electricity, and the magnet coil in it is controlled by low pressure controller 4.When connector 3 occurs coming off or is loosening, the state of connector 3 internal short-circuit switches 6 can change, because short circuiting switch 6 is in parallel with indicator lamp 5, therefore short circuiting switch 6 relations indicator lamp 5 and whether can be accessed low-voltage supply line, the state of short circuiting switch 6 changes the state that will inevitably cause indicator lamp 5 and changes, indicator lamp 5 or become and extinguish state by illuminating state, or become illuminating state by extinguishing state.No matter indicator lamp 5 is become by short circuit by access state, or become access state by short-circuit condition, the electric parameter of low-voltage supply line can change thereupon, and low pressure controller 4 captures the change of this kind of electric parameter, then the supply of control contactor 7 cut off high electric power.
Only show the circuit conditions to a kind of consumer power supply in Fig. 1, because the high pressure consumer of elec. vehicle is more, need to draw a plurality of Connector Clips, Given this, the scheme that the utility model is taked is with reference to Fig. 2 and Fig. 3, lead to many high-voltage transmission branch lines on the high-tension current transmission line, all be connected with connector 3 on each high-voltage transmission branch line, be connected with the short circuiting switch 6 interior with each connector 3 indicator lamp 5 one to one on low-voltage supply line, the coil power supply end that all is in series with contactless switch 7 and each contactless switch 7 on each high-voltage transmission branch line all is electrically connected on low pressure controller 4.After adopting said structure, can indicate respectively the plug corresponding with it 3 whether to come off or become flexible by each indicator lamp 5, in addition, by the circuit parameter change of low-voltage circuit, low pressure controller 4 can have been learnt that plug 3 comes off or become flexible, but which plug 3 is difficult to judge is.In view of the above problems, the utility model is taked again two kinds of measures: the first, and the resistance value size of each indicator lamp 5 of employing is different, and the internal resistance value of each indicator lamp 5 varies in size; The second, the resistance size of all connect on each indicator lamp 5 resistance and each resistance is different.By the size of the resistance to each resistance or indicator lamp 5 internal resistances, set, the corresponding indicator lamp 5 of each connector 3, a corresponding resistance, low pressure controller 4 can learn it is which resistance has accessed low-voltage supply line easily by the different voltage signal of its acquisition, thereby can learn it is that problem has appearred in the connector 3 of which branch road, and then can control targetedly the on off mode that cuts off contactless switch 7 on this branch road.
Embodiment shown in Fig. 2 and Fig. 3 has provided respectively two cover control programs, and four the high pressure consumers 2 of all take in two sets of plan are example, i.e. device A, equipment B, equipment C and equipment D.In circuit shown in Fig. 2, the contactless switch 7 in the supply line of each equipment is in parallel, between each equipment, is all independent power on/off, and the status that also can be understood as each equipment is equality.And in the circuit shown in Fig. 3, device A is main equipment, and contactless switch 7 corresponding to device A is connected on the main line of high-tension current, when plug 3 corresponding to device A comes off or be loosening, low pressure controller 4 can be controlled a cutting high-tension electricity and supply with, and each equipment all can not normally move.In Fig. 3, if problem has appearred in the plug 3 of equipment B, equipment C and equipment D, low pressure controller 4 is only controlled the electric power that cuts off problematic branch road and is supplied with, and does not affect the supply regular power of other circuit.
With reference to accompanying drawing, for the ease of the maintenance under the vehicle electroless state, the utility model also comprises the simultaneously Manual maintenance switch 8 of cut off high electric transmission line and low-voltage supply line.
Concrete installation site for each parts on vehicle, not shown in accompanying drawing, the consideration that takes into account the inner space of vehicle and easy access and control, the utility model adopts following scheme: each indicator lamp 5 is arranged on the instrument face plate of vehicle cab; Each connector 3 and each contactless switch 7 and Manual maintenance switch 8 are arranged on the power supply switch box of vehicle jointly.
In sum, the utility model is not limited to the above-mentioned specific embodiment.Those skilled in the art, under the prerequisite that does not break away from spirit and scope of the present utility model, can do some changes and modification.Protection domain of the present utility model should be as the criterion with claim of the present utility model.
