Description
Technical field
The utility model controller for electric vehicle technical field relates in particular to the controller for electric vehicle housing.
Background technology
Controller for electric vehicle is the startup, operation, advance and retreat, the speed that are used for controlling electric vehicle motor, stop and the kernel control chip of other electronic device of electric motor car.General controller for electric vehicle, comprise housing, enclosure interior is mounted with circuit control panel, circuit control panel itself as power device exists ventilation, waterproof needs, have at present by improving the controller housing structure, thereby satisfy the ventilation of circuit control panel, waterproof needs, for example, Chinese patent 200420058175.X proposes a kind of controller for electric vehicle water-tight device, this device comprises: the controller for electric vehicle housing, housing is provided with and can holds the electronic circuit board opening of packing into, and the lead-out wire that links to each other with electronic circuit board stretches out outside the shell, seals by sealing gasket between cover plate and opening.To inserting hole separately should be arranged, inserting hole and lead-out wire closely cooperate on sealing gasket for every lead-out wire, and cover plate is provided with lead-out wire and interts mouthful, is provided with resin embedding layer with the lead-out wire corresponding position on the cover plate.Because inserting hole and lead-in wire closely cooperate, and have certain waterproof effect; And resin embedding layer fitted seal pad, the hole complete closed that capillary can be seeped water makes controller for electric vehicle reach waterproof effect.Sealing resin not in the housing, sealing gasket is provided with inner fovea part simultaneously, and cover plate is provided with the corresponding recess of sealing gasket inner fovea part, and resin embedding layer makes resin embedding layer can not come off this recess sealing.
The weak point of such scheme is: just for sealing between housing and lead-out wire, when all seals were sealed, after electric motor car travelled rapidly, power device gathered a large amount of heats, because the complete closed heat dispersion is not ideal enough.In case gasket seal and resin embedding layer closed performance are bad simultaneously, steam enters and very easily damages circuit control panel.
Head it off how better improves ventilation, the waterproof effect of controller, then is the problem that the utility model faces.
Summary of the invention
The utility model provides a kind of controller for electric vehicle housing, can solve the controller for electric vehicle housing seal weak effect that prior art exists, thereby influence the ventilation of controller for electric vehicle, the problem of waterproof effect.
For solving the problems of the technologies described above, the utility model is achieved by the following technical solutions:
A kind of controller for electric vehicle housing is equipped with the circuit control panel of encapsulating in the housing, described housing comprises housing body and both sides end cap, and wherein, described two side ends covers and has ventilation hole and pod apertures.
In the technical solution of the utility model, also have following technical characterictic: end cap middle part, described both sides has some ventilation holes, has pod apertures by the edge all around.
In the technical solution of the utility model, also have following technical characterictic: described two side ends covers the middle part and has some ventilation holes.
In the technical solution of the utility model, also have following technical characterictic: a side end cap of described housing is " recessed " font, the baffle plate of pegging graft at end cap " recessed " v notch v place, and baffle plate base and end cap " recessed " v notch v base forms the wire harness hole.
In the technical solution of the utility model, also have following technical characterictic: described housing body surface has fin.
In the technical solution of the utility model, also have following technical characterictic: described wire harness hole number is two.
In the technical solution of the utility model, also have following technical characterictic: described wire harness hole is for circular or oval.
In the technical solution of the utility model, also have following technical characterictic: described both sides end cap keeps to the side all to have pod apertures along the place.
Compared with prior art, advantage of the present utility model and good effect are:
1, the two side ends of housing covers by the edge and has pod apertures, and this pod apertures plays the effect of ventilation simultaneously, and it is arranged on place, end cap base, and the silt or the water that are splashed in the controller housing can be flowed out along pod apertures.
2, two side ends covers the middle part and has some ventilation holes, and this ventilation hole plays good ventilation and heat effect.
3, a side end cap of housing is " recessed " shape, the baffle plate of pegging graft at end cap " recessed " v notch v place, and baffle plate base and end cap " recessed " v notch v base forms the wire harness hole.Can be put into wire harness in the groove of end cap earlier in process of production, an end of band socket is placed on the end cap outside, then baffle plate is plugged on the end cap, efficiently solves general harness band and the very difficult problem that wears out from the wire harness hole of socket.
4, housing body surface fin effectively plays thermolysis.
The utility model electric controller housing, with lower cost, novel structure efficiently solves ventilation, the waterproof problem of circuit control panel, can be widely used in the various electric motor cars.
