Description
Technical field
The utility model belongs to the technical field of new-energy automobile high-pressure system design, particularly a kind of new-energy automobile high pressure master control box assembly.
Background technology
At present, owing to there is a lot of high voltage electric device in new-energy automobile structure, vehicle extensively adopt high pressure master control box assembly be used for the distribution of high tension supply.
The following defect of high pressure master control box assembly ubiquity extensively adopted before this: 1, mostly be bolt with the connection mode of high-voltage wiring harness and fix, causes wire harness dismounting complex steps, consuming time longer; 2, do not possess high-pressure system coupled condition measuring ability and measuring ability of uncapping, service personnel has the possibility directly contacted with high-tension current, there is certain potential safety hazard; 3, the screen layer of high-voltage wiring harness needs assembler's manual crimp to the shell of high pressure master control box, and the shielding properties of complete machine cannot ensure; 4, complete machine water resistance need lean on assembler gland head to be tightened, and complete machine water resistance cannot ensure; 5, high-voltage relay lacks corresponding flywheel diode, making high-voltage relay lack protection when cutting off, there is certain influence to components and parts such as the aerotrons on life-span of high-voltage relay and circuit; 6, protection is lacked to the low-pressure section such as high-pressure section and housing, the risk having high-low pressure to contact when collision happens;
Utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of new-energy automobile high pressure master control box assembly.
The technical solution of the utility model is achieved in that
A kind of new-energy automobile high pressure master control box assembly, the fuse 1 comprising housing 5, low voltage connector 2, high-tension connector 6, high-voltage busbar 3 and be arranged on high-voltage busbar 3, described high-voltage busbar 3 is also equipped with high-voltage relay and flywheel diode 4 thereof, described high-tension connector 6 is plug-in type high-tension connector.
The madial wall of described housing 5 is equipped with micro-switch 7.
Outside face and the inside face of described high-voltage busbar 3 and housing 5 are all covered with insulating material.
High-voltage relay on described high-voltage busbar 3 and flywheel diode 4 thereof and fuse 1, in order to control the break-make of high-tension line, are connected with external electric device with low voltage connector 2 by high-tension connector 6.
High pressure master control box assembly beneficial effect of the present utility model is as follows:
1, be allly two sectional type plug with the connection mode of high-voltage wiring harness and be connected, without the need to assembling-disassembling bolt, save man-hour;
2, possess high-voltage interlocking and measuring ability of uncapping, when high-voltage wiring harness does not connect or high pressure master control box upper cover is opened, high pressure master control box can send signal to vehicle control device, and vehicle cannot be powered on by high pressure;
3, adaptor union has function of shielding to spigot, and assembly crewman only need by adaptor union to inserting the shielding properties that just can ensure complete machine;
4, adaptor union is IP67 to inserting rear water resistance, and assembly crewman only need by adaptor union to inserting the water resistance that just can ensure complete machine;
5, the flywheel diode that is applicable to of high-voltage relay coupling, can life-span of available protecting relay;
6, by increasing insulating material in high-voltage busbar edge and shell inner surface, the risk that when greatly reducing vehicle collision, high-pressure section directly contacts with low-pressure section.

Detailed description of the invention
Detailed description of the invention of the present utility model is described in detail below in conjunction with Figure of description.
As shown in Fig. 1 a, Fig. 1 b and Fig. 2, a kind of new-energy automobile high pressure master control box, comprises fuse 1, low voltage connector 2, high-voltage busbar 3, high-voltage relay and flywheel diode 4 thereof, housing 5, high-tension connector 6, micro-switch 7.Described high-tension connector 6 uses plug-in type high-tension connector, realizes directly plugging, such that the assembling of complete machine and high-voltage wiring harness is simple and easy, water resistance good, advantages of good shielding performance and possess high-voltage interlocking function; Be arranged on the micro-switch 7 in case inside face, the detection of uncapping of master control box can be realized; High-voltage busbar 3 and housing 5 are covered with insulating material at outside face and inside face respectively, the risk that when greatly reducing vehicle collision, high-pressure section directly contacts with low-pressure section.
Specific works process of the present utility model is as follows:
As shown in Figure 3, when there is high-tension current when between HV+ and HV-, high-tension current distributed to the electric machine controller of rear end, air-conditioning compressor, operator's compartment PTC, Vehicular charger and DC/DC, battery hot-water heating PTC by shown inside cabling mode, and fill socket soon by this circuit to power battery charging.When the upper cover of high pressure master control box assembly is opened, micro-switch 7 can be upspring, and sends signal, vehicle cannot be powered on by high pressure to entire car controller.When high-voltage relay disconnects, the induction electricity that relay coil produces is failed to be convened for lack of a quorum and to be discharged by flywheel diode, can not impact other components and parts on high-tension connector and circuit.
