Device is damaged, and entire bus or logistic car will stop, and can not work, and interior air-conditioning will lose power supply supply, compressor
It can not work, vehicle interior temperature rapid increase causes personnel uncomfortable, due to the particularity of public transit system and logistics system, once vehicle
It casts anchor, will cause the problems such as urban mass-transit system is stopped with logistics transportation strike, the structure of supply convertor includes that shell is (outer
It is have radiating ribs outside shell, internal by reserved installation hole location), internal insulating layer, circuit board (letter boards) form, have above mainboard
Screw hole is bolted in the hole location of interior of shell, and feature board is by being welded to connect on mainboard, then in entire shell
Internal injecting glue prevents internal component from loosening or falling off because of vibration in vehicle operation, due to this special
Assembling structure, in largely actual use process and maintenance process, it has been found that supply convertor internal damage is all function
Energy plate (daughter board), template and other components are seldom damaged, therefore in maintenance, needing will be above entire mainboard and daughter board
Injecting glue get rid of, mainboard of then dismantling, the daughter board renewed by way of dissolving scolding tin, then injecting glue again, whole process
It is more than about 1 hours, time-consuming and laborious, therefore the utility model proposes self-test type new-energy automobile DC power convertors.

Copper post is provided with daughter board relative to the other side of motherboard, and the daughter board both ends are connected on snap-gauge, relative to son on the snap-gauge
It is fixedly connected with partition on the other side inner wall of plate, is fixedly connected with hinge on one end of motherboard on the snap-gauge, it is described
Fixing bolt is provided with relative to interspersed on the other side snap-gauge of daughter board on partition.
As a kind of optimal technical scheme of the utility model, the articulate is connected to one end of fixed link, described
Fixed link is fixedly connected relative to the other end of hinge with motherboard.
As a kind of optimal technical scheme of the utility model, the fixing bolt is plugged in encapsulating close to one end of motherboard
In the encapsulating hole of plate.
As a kind of optimal technical scheme of the utility model, the size in the encapsulating hole is greater than the size of fixing bolt.
As a kind of optimal technical scheme of the utility model, the encapsulating plate is fixedly mounted on motherboard.
The utility model beneficial effect achieved is: the present apparatus is changed by hinge block first by being provided with snap-gauge
Daughter board is placed in support copper post by the angle of plate so that snap-gauge opens, and in rotation snap-gauge, snap-gauge is stuck in partition side, will be consolidated
Determine bolt and across snap-gauge one end of fixing bolt is plugged in inside encapsulating hole, using casting glue fixing bolt is fixed
Inside encapsulating hole, when disassembly, casting glue need to only be melted, fixing bolt can be removed, to open snap-gauge, remove daughter board,
Such design, being capable of more convenient quick replacement daughter board.
