Abstract
The utility model discloses a kind of water-proof electric vehicle controller, it comprises housing, seal base, circuit board assembly and cable; Housing lower end is uncovered, and lower edge is provided with flange; Circuit board assembly is fixed on seal base, and seal base is fixedly connected with flange and is packaged in by circuit board assembly in housing chamber; One sidewall of housing is provided with a slot, is provided with some stitch in this slot; Cable is connected with a plug, and this plug is provided with some pin holes, and the some wires in cable are connected with pin hole respectively.Which simplify the shell structure of controller for electric vehicle, make it easier for installation, and design comparatively science, improve the tightness of housing, improve the water resistance of controller for electric vehicle; In addition, it makes the installation, maintenance of controller for electric vehicle, changes convenient operation more.
Description
Technical field
The utility model relates to a kind of electronic control device, particularly relates to a kind of water-proof electric vehicle controller in electric motor car.
Background technology
Controller for electric vehicle, be used for controlling the startup, operation, advance and retreat, speed, stopping etc. of electric vehicle motor, simultaneously for other electronic device of electric motor car provides control, it is one of most important core component in electric motor car, and its performance directly affects stability and the fail safe of electric motor car.Sometimes electric motor car travels in sleety weather or environment of paddling, and controller is the core of whole circuit part, and it has excellent water resistance can ensure the safe operation of electric motor car in above-mentioned environment.Current controller for electric vehicle is fixed in housing at circuit board assembly usually, and the two ends of housing are the end plates be bolted, and end plate be provided with power circuit board lead-in wire through through wires hole, cause housing imprecision, when travelling in sleety weather or environment of paddling moisture even water can enter in housing, cause circuit board assembly cisco unity malfunction, even cause controller for electric vehicle to burn and reduce controller useful life.
Utility model content
For overcoming above-mentioned technical problem, it is simple that the utility model provides a kind of structure, and easily implement, housing tightness is good, is conducive to improving controller for electric vehicle water proofing property, extends the water-proof electric vehicle controller in its useful life.
For realizing above-mentioned technical purpose, the utility model adopts following scheme: a kind of water-proof electric vehicle controller, comprises housing, seal base, circuit board assembly and cable; Described housing lower end is uncovered, and be made up of four sidepieces integrally and top, the lower edge of housing is provided with vertical outward extending flange; Described circuit board assembly is fixed on seal base, and seal base is fixedly connected with by screw with flange and is packaged in by circuit board assembly in housing chamber; Sealing gasket is provided with between described seal base and flange; One sidewall of described housing is provided with a slot, is provided with some stitch be connected with circuit board assembly via line in this slot; Described cable is connected with a plug that can coordinate with slot grafting, and this plug is provided with some pin holes that can coordinate with the stitch grafting in slot, and the some wires in described cable are connected with pin hole respectively.
When plug inserts slot, stitch inserts in pin hole just, and the some wires in cable then realize being electrically connected with circuit board assembly.
The two ends of described seal base extend to beyond housing respectively, and respectively have installing hole respectively at two ends.
The utility model has following beneficial effect: the shell structure which simplify controller for electric vehicle, makes it easier for installation; Because housing assembling parts is few, and design comparatively science, improve the tightness of housing, circuit board assembly can be avoided to soak, improve the water resistance of controller for electric vehicle; In addition, cable realizes being connected with circuit board assembly through stitch, pin hole, on the one hand without the need to the wire hole that processing on housing is drawn for cable, be conducive to the tightness improving housing, then make the installation, maintenance of controller for electric vehicle on the other hand, change convenient operation more.

Fig. 3 is the view that the utility model disassembles rear other direction.
In figure, 1, installing hole, 2, seal base, 3, cable, 4, plug, 5, housing, 6, stitch, 7, flange, 8, slot, 9, sealing gasket, 10, circuit board assembly, 11, pin hole.
Embodiment
Shown in Fig. 1,2,3, a kind of water-proof electric vehicle controller disclosed in the utility model, it comprises housing 5, seal base 2, circuit board assembly 10 and cable 3; The described worn-out mouth in housing 5 lower end, be made up of four sidepieces integrally and top, the lower edge of housing 5 is provided with vertical outward extending flange 7; Described circuit board assembly 10 is fixed on seal base 2, and seal base 2 is fixedly connected with by screw with flange 7 and is packaged in by circuit board assembly 10 in housing 5 chamber; Sealing gasket 9 is provided with between described seal base 2 and flange 7; One sidewall of described housing 5 is provided with a slot 8, is provided with some stitch 6 be connected with circuit board assembly 10 via line in this slot 8; Described cable 3 is connected with a plug 4 that can coordinate with slot 8 grafting, and this plug 4 is provided with some pin holes 11 that can coordinate with stitch 6 grafting in slot 8, and the some wires in described cable 3 are connected with pin hole 11 respectively; When plug 4 inserts slot 8, stitch 6 inserts in pin hole 11 just, and the some wires in cable 3 then realize being electrically connected with circuit board assembly 10; The two ends of described seal base 2 extend to beyond housing 5 respectively, and respectively have installing hole 1 respectively at two ends, are convenient to controller for electric vehicle and are installed in electric motor car.
Which simplify the structure of the housing 5 of controller for electric vehicle, make it easier for installation; Because housing 5 assembling parts is few, and design comparatively science, improve the tightness of housing 5, circuit board assembly 10 can be avoided to soak, improve the water resistance of controller for electric vehicle; In addition, cable 3 realizes being electrically connected with circuit board assembly 10 through stitch 6 and pin hole 11, on the one hand without the need to the wire hole that processing on housing 5 is drawn for cable 3, be conducive to the tightness improving housing 5, then make the installation, maintenance of controller for electric vehicle on the other hand, change convenient operation more; In addition, certain waterproof action can be played to stitch 6 and pin hole 11 when plug 4 inserts slot 8.
