The specific embodiment
As shown in Figure 1, electronlmobil subcontrol of the present utility model, with a high direct voltage contactless switch KM0, controls being switched on or switched off of major loop high pressure, replaces being originally placed on the hands off device of headstock, makes headstock layout easy and succinct.While powering on, first connect total contactless switch protection contactless switch KM1, its secondary contact are controlled total contactless switch KM0 adhesive, and (KM1 adhesive triggers KM0 to its secondary contact and picks certain hour time delay, in the time of guaranteeing the each adhesive of KM0 like this, both end voltage one is decided to be zero, thereby greatly extend the service life of KM0), then connect precharge contactless switch KM3, when pre-charge voltage reaches setting value, adhesive frequency converter main contactor KM2 after judgement is normal, start frequency converter, after time delay, disconnect again precharge contactless switch KM3, after judgement contactless switch action feedback signal is all normal, judge that more whether charger and auxiliary actuator are in normal condition, normal words start DCDC charger, and according to atmospheric pressure signal enabling or stop inflation pump.KM4 and KM5 are control loop break-makes when charging.When charging occurs extremely as overcurrent etc., these two contactless switchs can disconnect automatically.
The structure of the subcontrol as shown in Fig. 2,3 and 4 is as follows:
Outward appearance is described, and subcontrol ACU1 adopts Sheet-metal machine box, and degree of protection is IP54, surface plastic spraying.Cabinet only has 2 inlet wire faces, i.e. the plug-in low pressure inlet wire of right flank and front bolt compression joint type high pressure inlet wire.After front cover plate is opened, can access major loop high pressure thick line, because inlet wire termination layout high concentration, so fuse and relay for automobile can be placed in both sides, makes wiring and maintenance panel unified outwardly.The advantage of layout is that the wiring space of right flank can be compressed to minimum like this, only has a positive face to need wiring and maintenance, can utilize well space limited on vehicle.
Inner structure is described, and the inner dense layout that adopts, makes full use of solid space, and inner thick line all adopts copper bar to connect, and has both been convenient to mass production, has improved well again the reliability of complete machine; First the control line of all contactless switchs is all inserted in the PC board of excessive use with plug nearby, unification is connected to master board with connector again, make like this length of control line all be optimized to shortest length, when having improved equipment maintainable, guaranteed still neat appearance relatively of cabling in finite space.Described electronlmobil subcontrol also comprises pre-charge resistance and leakage protection module, has improved charge efficiency and safety performance.
Mounting structure is described, when controller is installed, two angles inside adopt the briquetting of troughs of belt to fix, by 2 the outer bolts of dismantling, just can pull down like a cork controller, this maintenance for vehicle or maintenance bring a lot of convenience, if because fix with bolt by 2 inner angles, probably because space is former thereby be difficult to dismounting.
