Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the disclosed a kind of EPS controller of the utility model embodiment;
Fig. 2 is the structural representation of PCB in the disclosed a kind of EPS controller of the utility model embodiment;
Fig. 3 is the structural representation of radiating shell in the disclosed a kind of EPS controller of the utility model embodiment.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Referring to Fig. 1, the utility model embodiment discloses a kind of structural representation of EPS controller, EPS(Electric Power Steering, electric boosting steering system) controller comprises: shell 11, shell 11 inside are provided with the radiating shell 12 that is positioned at bottom and printed circuit board (the Printed circuit board that is positioned at upper strata, PCB) 13, on radiating shell 12, be provided with identical with radiating shell 12 materials and integrated heating panel 14, upper integrated driving circuit and the control circuit of being provided with of PCB13, power component 15 in described driving circuit is connected (Fig. 1 show be the schematic diagram after power component 15 and heating panel 14 splits) with heating panel 14.
In summary it can be seen, because radiating shell 12 is identical and one-body molded with heating panel 14 materials, therefore between radiating shell 12 and heating panel 14 without binder, the heat that power component 15 produces can be transmitted to rapidly radiating shell 12 by heating panel 14, and increased the heat-conducting area of power component 15, the heat that so power component 15 can be produced exports to rapidly in air, realized and guaranteed that EPS controller does not take under too much arrangement space prerequisite, improve EPS controller and obtain heat dispersion, temperature rise while having controlled timely the work of EPS controller, guaranteed the normal work of EPS controller.And, the one-body molded fastness that also increases EPS controller of radiating shell 12 and heating panel 14.
