Description
Technical field
The utility model relates to a kind of controller, refers to a kind of steering controller especially.
Background technology
Electric booster steering controller is the electronic-controlled power steering controller that a kind of direct dependence motor provides auxiliary torque, mainly contains control unit and power drive unit and constitutes.The lightweight of vehicle will certainly reduce the space in cabin as far as possible, because spatial constraints, the overall dimension of controller can not be excessive, and weight can not be too big, and it is compact that structure is wanted.This also proposes high request to the electronic power components as one of controller core element simultaneously, needs the more power drive element of high power density.The increase of power certainly will will produce too many heat, and this just requires controller integral heat sink effect to get well, and will influence the element operate as normal if heat can not lose, and whole system sensitivity will descend, and fail safe will be on the hazard.
Design in the past can not be satisfied these instructions for uses far away, and entire controller causes radiator thermal capacity not enough because radiating surface is single or the radiator material is incorrect, and the controller radiating effect is bad.Secondly controller internal structure too disperse, in disorder, each module is system not, needs too much lead or pin conducting, has reduced controller and even vehicle reliability and fail safe, and not attractive in appearance, is not easy to maintenance, maintenance.
See also Fig. 7; Controller in the past uses the FR-4PCB circuit board 10 with independent function; For the power device 3 that fixedly caloric value is high, and can the heat of power device 3 in time be passed, also need one have independent function double-layer aluminium-base PCB circuit board 11; And then double-layer aluminium-base PCB circuit board 11 is connected with heat radiation matrix 12, connected mode can be through lead or through conduction metal pin or metal column well.Like this among entire controller, a plurality of PCB with independent function of existence can increase volume, assembly difficulty and the dismounting maintenance difficulty of controller; And can increase the transmission path of electric current; Increase thermal resistance, cause the caloric value of whole built-in system to rise, influence the operate as normal of controller.Secondly, adopt too much connected mode to cause controller architecture in disorder, not attractive in appearance, and the reliability of loosening image controller appear in the junction.
In addition; Controller is in the past often only considered through independent heat radiation matrix heat radiation; Utilize loam cake as auxiliary heat radiation carrier and ignored, loam cake only selects for use the not too good cold-reduced sheet stamping parts of heat radiation and conductive coefficient as material, even to select the bigger plastics of thermal resistance for use be material.Cause controller can only folk prescription to through a kind of heat radiation carrier heat radiation, this will influence the radiating effect of controller.Also influence the overall appearance of controller simultaneously.
In view of these reasons, be necessary controller is further improved, optimizes, improve the radiating effect of controller, structural compactness, aesthetic property and the reliability of raising controller.
