See also Fig. 1,2,3; Show the electric machine controller 100 that the utility model embodiment provides; Comprise interior empty shell 11, be placed in control element 12 and pcb board 13 in the shell 11; Control element 12 comprises control element main body 121 and by the extended pin 122 in main body 121 bottoms of control element 121; Pin 12 is installed on the pcb board 13, and folder is established an insulation glue-line 16 between the inwall 112 of control element main body 121 and shell 11, main body 121 insulation of control element 121 is fitted in the inwall 112 of shell 11 through insulation glue-line 16.
Empty in the shell 11, have an inner chamber 110, control element 12 all is placed in this inner chamber 110 with pcb board 13.As shown in Figure 2, the cross section of shell 11 is a rule or irregularly shaped, is illustrated as irregularly shapedly, roughly is up-narrow and down-wide structure, through adopting down wide structure, settles control element 12 and pcb board 13 so that enough spaces to be provided.Shell 11 extends internally one and has the protuberance 114 on a plane 115, and the main body 122 of control element 12 fits in the plane 115 of protuberance 114.
Shown in Fig. 2 and 3; Shell 11 outwards convexes with the vent rib 116 that extends along housing axis radially; Vent rib 116 surfaces have micro-structural 117, and micro-structural 117 can be trickle concaveconvex structure, or ripple, wavy structure; To increase the surface area of vent rib 116 greatly, further improve radiating efficiency.
Further; Inwall 112 is provided with a draw-in groove 113; One end of pcb board 13 is embedded in this draw-in groove 113; The other end of pcb board 13 is and the main body 122 applying ends of control element 12 that the end of this applying compresses through securing member 15, so that the main body 122 of control element 12 fits tightly in inwall 112.Particularly; Shell 11 is provided with a plurality of said securing members 15 in the position corresponding to a plurality of control elements 12; Securing member 15 passes shell 11 and presses on the surface of pcb board 13 away from control element 12, and pad is provided with a waterproof gasket 152 between the outer surface of securing member 15 and shell 11.
Front apron 102 and backboard 103 that shell 11 comprises housing 101 and is installed on housing 101 two ends respectively, housing 101 is tubulars of a both ends open, just the cross section is rule or irregular shape.Front apron 102 and backboard 103 promptly are sealed in the both ends open place of housing 101.Press from both sides respectively between the two ends of front apron 102 and backboard 103 and housing 101 and establish a rubber sheet gasket 104, be used for water-tight.Front apron 102 is provided with ply-yarn drill gland 106.Have screw 118 on the housing 101, front apron 102 all offers through hole with backboard 103 and rubber sheet gasket 104, to let screw 105 pass and be anchored on screw 118.Front apron 102 all is provided with five metals pressing plate 107 with backboard 103; Five metals pressing plate 107 structures and the mounting means of rear and front end are similar; Present embodiment is an example with front apron 102, offers porosely on the front baffle board five metals pressing plate 107, and housing 101 is provided with bottom screw 119 at the front end of corresponding front apron 102; Through bottom screw 109 front baffle board five metals pressing plate 107 is anchored on the end of housing 101, front apron 102 is pressed in the front end of housing 101.
In illustrated embodiment; The pin 122 of control element 12 is inserted on the pcb board 13; Be exposed to main body 122 that the outer tops of pcb board 13 are folded into control element 12 and be basically parallel to protuberance 114 planes 115 of pcb board 13 and shell 11, the angle of bending is roughly 90 degree.In the practical application, control element 12 can be the MOS power tube.Because pin 122 is basically vertically to be inserted on the pcb board 13, therefore,, the main body 122 of control element 12 is fitted in inwall 112 through bending.In another embodiment,, pin 122 can be need not bend can the main body 122 of control element 12 be fitted in inwall 112, for example, pin 122 is basically parallel to the situation on protuberance 114 planes 115.
Glue-line 16 is located between the plane 115 of main body 121 and protuberance 114 of control element 12, and glue-line 16 has certain compressibility, for example can be insulating material such as EVA.The thinner thickness of glue-line 16; Basically do not influence the heat-conducting effect between the inwall 112 of main body 121 and shell 11 of control element 12, but insulation property are better, thereby reach the more insulating requirements of high pressure of ability; And don't influence radiating effect; The electric machine controller 100 of present embodiment can be anti-more than 1800 volts, in some preferred embodiments, and also can anti-2000 volts of above high pressure.
In the bottom side of control element 12, folder is established an elastic parts 17 between the main body 121 of control element 12 and the pcb board 13, for example sheet rubber etc.Control element 12 is the control element of a plurality of marshallings, and the main body 121 of a plurality of control elements 12 fits in the inwall 112 of pcb board 13 and shell 11 respectively through one deck glue-line 16 and elastic parts 17 in both sides.Glue-line 16 is whole piece structures, and elastic parts 17 comprises a matrix 171 and is located at a plurality of elastic mats 172 on the matrix 171, the corresponding respectively main body 121 that flexibly supports a plurality of control elements 12 of a plurality of elastic mats 172.Because the main body 121 of a plurality of control elements 12 is the separate version that arranges in a row; Each elastic mat 172 supports the main body 121 of a control element 12; Compress pcb board 13 through securing member 15 again; Make the main body 121 of each control element 12 all fit tightly, can be independent of each other between the main body 121 of a plurality of control elements 12 with the inwall 112 of shell 11.
Above-mentioned electric machine controller 100 is inserted in a plurality of control elements 1 on the pcb board 13 through pin 122 earlier when mounted, with pin 122 bendings; And elastic parts 17 is set on pcb board 13, and make elastomeric pad 172 main body 121 of support and control element 12 respectively, on main body 121, post glue-line 16; Again they are packed in the housing 101; Alignment surface 115, and then be against on the pcb board 13 with securing member 15, make main body 121 be adjacent to plane 115 through glue-line 16; And then front apron 102, backboard 103 be fixed in the two ends of housing 101, plate washer five metals pressing plate 107 fastening front and rear baffles 102,103 before and after using respectively.Hence one can see that, when above-mentioned electric machine controller 100 is installed, through the inwall 112 of control element main body 122 is fitted respectively pcb board 13 and shell 11, control element 12 tightly fitted in the inwall 112 of shell 11, and installation process is simple and efficient.
Above-mentioned electric machine controller 100 through insulation glue-line 16 with inwall 112 mutually insulateds of control element 12 and shell 11 and make its inwall that fits in shell 11 112; Thereby the heat of control element 12 can conduct to shell 11; And make inwall 112 insulation of control element 12 and shell 11, thereby reach the more insulating requirements of high pressure of ability through glue-line 16.Because shell 11 has relatively large surface area, help improving radiating effect, improve the function operational reliability of controller, so electric machine controller 100 can have better radiating effect, can satisfy the requirement of anti-more high pressure simultaneously.So just avoid the use of extra heating panel, reduce cost, nor need complicated radiator structure, make these controller 100 low cost of manufactures.Above-mentioned electric machine controller can cooperate motor to use, and is widely used in the motor-driven device of various needs.
More than be merely the preferred embodiment of the utility model,, any modification of being done within all spirit at the utility model and the principle, be equal to and replace and improvement etc., all should be included within the protection range of the utility model not in order to restriction the utility model.
