Description
Technical field
The utility model relates to a kind of controller for electric vehicle structure, belongs to field of mechanical technique.
Background technology
Current controller for electric vehicle generally uses the heat radiation aluminum strip of " π " structure, the operation when assembling of this structure is very difficult, power tube position and the span after being assembled on aluminum strip arranged due to left and right two are fixed, power tube can be caused to be out of shape when plug-in unit, thus make power tube and heat radiation aluminum strip can not close contact completely, cause heat radiation bad, Long-Time Service will cause power tube to burn, two-sided installation is wanted when assembling power tube, operating efficiency is low, to matching requirements and materials processing precision high, simultaneously too fastly cause failure welding and circuit board excessive deformation because this heat radiation aluminum strip weight is dispelled the heat when wave soldering greatly, cause finished product yield low.
Utility model content
The utility model provides a kind of controller for electric vehicle structure, the above defect can be overcome, with tight lock press strip, two heat radiation aluminum strips are tightly locked on shell, top surface area due to the aluminum strip that dispels the heat less not easily generation flexural deformation can reach and contact completely with shell after tightly locking with shell, accomplish the radiating state that overall contact is good to ensure that the reliability of controller.
For solving above technical problem, the utility model provides following technical scheme: comprise shell, the circuit board be connected in shell, the heat radiation aluminum strip be connected on circuit board, power tube and springs steel disc, described power tube is connected to the both sides of heat radiation aluminum strip, heat radiation aluminum strip is stairstepping, and power tube is installed in the low order of heat radiation aluminum strip; The two ends of described springs steel disc are pressed on the heat radiation high-order of aluminum strip and the equidirectional side of power tube, the high-order being connected to heat radiation aluminum strip by screw of springs steel disc, one end that springs steel disc is pressed in power tube is provided with the support end that springs steel disc one end is tilted.
Further, described heat radiation aluminum strip is Split type structure, the non-cascaded surface of heat radiation aluminum strip has the sunk structure that cross section is dihedral, sunk structure on two heat radiation aluminum strips is opposite, form the installing space of locking press strip, tight lock press strip is placed in this installing space, is close-coupled on shell by the heat radiation aluminum strip of split.
Further, the cross sectional shape of described locking press strip is isosceles trapezoid, end face has multiple screwed hole for being connected and fixed on shell.
Further, the two ends of described springs steel disc have the arcuate structure preventing crushing element.
Further, described springs steel disc has multiple screwed hole, be provided with multiple slot arranged in parallel on one side thereof.
This controller for electric vehicle structure that the utility model relates to, power tube spring steel plate is pressed on heat radiation aluminum strip, it is made to contact with fin closely, cast out and to screw hole on heat radiation aluminum strip, make area of dissipation increase decrease difficulty of processing and defect ware simultaneously, the heat radiation aluminum strip of separate type makes the operation when assembling power tube simplify, simultaneously because heat radiation aluminum strip is structurally the power tube problem on deformation being separated thus eliminating in the operation easier of plug-in unit and finished product; The heat radiation aluminum strip of " π " structure due to the area of end face large, adding easy bending in man-hour, when can not fully contact with shell completely with during shell close-fitting, have influence on shedding of heat, two heat radiation aluminum strips are tightly locked on shell by the tight lock press strip of this programme, top surface area due to the aluminum strip that dispels the heat less not easily generation flexural deformation can reach and contact completely with shell after tightly locking with shell, accomplishes the radiating state that overall contact is good to ensure that the reliability of controller.
