Below in conjunction with accompanying drawing the utility model embodiment is further described:

The 1st, drain pan, the 2nd, loam cake, the 3rd, circuit board, the 4th, electronic component, the 5th, support bar, the 6th, power tube, the 7th, screw, the 8th, press strip, the 9th, line outlet, the 10th, deep trouth, the 11st, the securing member of threaded structure, the 12nd, rubber cushion, the 13rd, groove, the 14th, deep hole.

Referring to Fig. 1-6, controller for electric vehicle of the present utility model, comprise circuit board 3, loam cake 2 and drain pan 1, circuit board 3 is inlaid between loam cake 2 and the drain pan 1, described loam cake 2 lower bottom parts are provided with the supporting bracket 5 of vertical direction, one side of described supporting bracket 5 is provided with the press strip 8 that is used for fixing circuit board 3, one side of described drain pan 1 be provided with line outlet 9, the bottom of described loam cake 2 be provided with the deep trouth 10 that parallels with described supporting bracket 5, inwall two sides of described deep trouth 10 are provided with the zigzag screw thread, and described drain pan 1 is connected with described loam cake 2 by the securing member 11 that is threaded structure.

The utility model can also comprise following technical scheme: the described circle rubber cushion 12 that between loam cake 2 and drain pan 1, is provided with, and the upper surface of the inwall of the shape of described rubber cushion 12 and described drain pan 1 matches; Described press strip 8 is provided with screw hole, and the screw 7 on the described screw hole is fixed on the power tube 6 on the described circuit board 3 on the supporting bracket 5; Be provided with the screw hole of perforation on the affiliated drain pan 1 with the correspondence position of deep trouth 10; Described rubber cushion 12 becomes stepped corresponding to the drain pan line outlet; Described deep trouth 10 is positioned at the outside of described rubber cushion 12.

The utility model comprises loam cake 2 and drain pan 1, and circuit board 3 is inlaid between loam cake 2 and the drain pan 1.The bottom of loam cake 2 is provided with the supporting bracket 5 of vertical direction, the centre of press strip 8 is porose and centre press strip 8 is inwardly recessed, the supporting bracket 5 of being close to loam cake 2, two power tubes 6 are arranged between two wings of press strip 8 and the supporting bracket 5, when screw 7 is fixed on press strip 8 on the supporting bracket 5 of loam cake 9, the realization of 8 pairs of power tubes 6 of press strip heat radiation, positioning action because the connecting as one of power tube 6 and circuit board 3, so realized location simultaneously to circuit board 3.Moreover, because a press strip 8 can be fixed two power tubes 6, just can reduce the screw hole of half, thereby simplify technology.

One side of the utility model drain pan 1 is provided with middle recessed line outlet, line outlet is higher than the outside near a side of inner chamber, and rubber cushion 11 becomes stepped corresponding to the shape of drain pan 1 lateral recess, high step is used for thin electric wire output, low step is used for thick line output, can look after the different electric wire of type like this, make the perfusion glue of line outlet also very easy, it is also easy to keep in repair.

Improvements to prior art of the present utility model are; As Fig. 3, being connected of loam cake in the past and drain pan is that the connected mode of screw and screw hole has become screw 11 and had the connected mode of the deep trouth 10 of zigzag screw thread purely, promptly as Fig. 3, deep hole 14 backs that screw 11 passes on the drain pan 1 directly are connected with the deep trouth 10 that has the zigzag screw thread, because two sides all are jagged screw threads about deep trouth 10, so screw 11 can be meshed with deep trouth 10 in the optional position in the deep trouth 10, reaches loam cake 2 and drain pan 1 close-connected effect.The hole of the loam cake before having avoided simultaneously, the size of the through hole of drain pan and mutual position relation must be mated very much, cause installing failure otherwise can not accurately locate; Even can barely screw on screw, also can infiltrate a series of defective of steam because the gap in screw and hole is big.

The deep trouth 10 and the loam cake 2 that have the zigzag screw thread can be cast as mould, hand over aluminium section bar plant to create again, have saved the operation of punching, tapping on loam cake 2 at the same time, and it is simple that technology is set like this, and cost does not increase yet.

Simultaneously, because deep hole 14 is arranged on the outside of the cavity of settling circuit board, and rubber cushion 12 is positioned at the inboard of deep trouth 10, the steam of entering from deep hole 14 can be subjected to the obstruct of rubber cushion 12 thus, and can not enter into the inner chamber at circuit board place.Thereby reached good waterproof effect.

In addition, as Fig. 6, the utility model is provided with the rubber cushion 12 that the upper surface with the inwall of drain pan 1 matches between loam cake 2 and drain pan 1, because the upper surface of the inwall of the shape of rubber cushion 12 and drain pan 1 matches, so rubber cushion 12 can be realized good water-tight effect.

Be provided with the groove 13 of a plurality of perforations around the bottom surface of drain pan 1, be used for sealant pouring and sealing, replaced in the past mode from the end face encapsulating, described groove 13 communicates with described line outlet 9, when encapsulating, the silica gel of perfusion can produce good sealing effectiveness and fix corresponding electric wire line outlet 10 from groove 13.

Assembling process of the present utility model is: referring to accompanying drawing 6, power tube 6 is fixed on the supporting bracket 5 of loam cake 9 (passing the hole of press strip 8 and supporting bracket 5 correspondences with screw 7) earlier with press strip 8, also just circuit board 3 has been fixed simultaneously, this moment rubber cushion 11 is put into the upper end of the inboard of drain pan 2, and the position corresponding to the line outlet 10 of drain pan 2 of electric wire by rubber cushion 11 extended to the outside, and (high step is used for thin electric wire output, low step is used for thick line output, and the gap of leading-out terminal is as much as possible little like this).The loam cake 9 that will have circuit board 3 then is placed in the cavity of drain pan 2, supporting bracket 5 is entered in the location notch in the drain pan, afterwards, 14 places screw on screw with deep hole, loam cake 9 and drain pan 2 are tightened up, last begin encapsulating from the groove 13 of the bottom surface of drain pan 2 again, the silica gel of perfusion can produce good sealing effectivenesss and fix corresponding electric wire line outlet 10.

Utilize technical scheme described in the utility model, or those skilled in the art designing the similar techniques scheme under the inspiration of technical solutions of the utility model, and reach above-mentioned technique effect, all is to fall into protection scope of the present invention.
