Specific embodiment
The present invention will be further described with reference to the accompanying drawings.
As shown in Figure 1 and Figure 5, the support base 100 of a kind of electric machine controller, is used to support and fixes inside electric machine controller
Composite bus bar 2 and high-voltage busbar 5, including bottom wall 30 and perpendicular to the side wall 10,20 of bottom wall 30.It is equipped on side wall 10,20
Multiple spacer portions and positioning region, so as to the external interface end interval of composite bus bar 2 and high-voltage busbar 5 and be fixed on support base 100
Same side.
In this case, two parts external interface end of composite bus bar 2, passes through the interval on the side wall of support base 100
Portion and positioning region are spaced and are fixed on the side A of support base 100.Similarly, the three parts external interface end of high-voltage busbar 5,
By spacer portion on the side wall of support base 100 and positioning region, also it is spaced and is fixed on the side A of support base 100.Pass through branch
The above-mentioned fixed form for supportting 100 pairs of composite bus bars 2 of seat and high-voltage busbar 5, can efficiently use the sky inside electric machine controller
Between, and then can reduce the overall volume of electric machine controller.Preferably, organic material of the support base 100 using lighter weight, example
Such as, epoxy resin is prepared.And hence it is also possible to keep electric machine controller lighter.
In a specific embodiment of the invention, as shown in Figures 1 to 4, bottom wall 30 is strip, side wall 10,20
Edge along the long side of bottom wall 30 is arranged.In order to keep apart composite bus bar 2 and high-voltage busbar 5 well, and it is also secured to
On the same side A of support base 100, side wall is divided into 20 two parts of the first side wall 10 and second sidewall.The first side wall 10 is for solid
Determine composite bus bar 2, second sidewall 20 is for fixing high-voltage busbar 5.Herein it should be noted that inside according to electric machine controller
Specific special case, can arbitrarily adjust the thickness and height of the first side wall 10 Yu second sidewall 20.For example, can be by first
Side wall 10 is configured to height and is higher than second sidewall 20, and thickness is less than the fixation wall of second sidewall 20.
In a specific embodiment of the invention, as shown in Figures 1 to 4, laterally set in the side A of the first side wall 10
There are 1 first longitudinal direction boss 11 and two first positioning holes 12.Specifically, the width of first longitudinal direction boss 11 is greater than 6mm, preferably
Ground, in order to be cooperated with external plug connector, the width of first longitudinal direction boss 11 is 7mm.It is vertical that first positioning hole 12 is located at first
To the two sides of boss 11.With similarly set-up mode, set in the side the A transverse direction of second sidewall 20 there are two second longitudinal direction boss
21 and three second location holes 22.Herein it should be noted that since first longitudinal direction boss 11 is spaced direct current electric connection, the
The two longitudinal interval of boss 21 exchange electric connections, therefore, the width of first longitudinal direction boss 11 is slightly larger than the width of second longitudinal direction boss 21
Degree.In order to preferably be cooperated with other component around, the height of second location hole 22 be can be set into less than the first positioning
The height in hole 12.
In of the invention one specifically embodiment, as illustrated in fig. 1 and 2, in second side for fixing high-voltage busbar 5
Wall 20 is equipped with the location notch hole 23 of strip.Location notch hole 23 is located under second longitudinal direction boss 21 and second location hole 22
Side, and the length of location notch hole 23 is greater than the cross direction profiles width of second longitudinal direction boss 21 and second location hole 22.In this feelings
Under condition, the three parts external interface end of high-voltage busbar 5 can pass through location notch hole 23, be limited in location notch hole 23 and upward
Bending.The three parts external interface end of high-voltage busbar 5 is finally fixed with three second respectively under the guiding role of location notch hole 23
Position hole 22 is aligned and is fixed.Two second longitudinal direction boss 21 separate the three parts external interface end of high-voltage busbar 5, to keep
Certain electric clearance and creepage distance.
In of the invention one specifically embodiment, as shown in Fig. 2, in the second sidewall 20 of high-voltage busbar 5, positioning
Fixation hole 24 is insured there are two setting in the lower section of slot 23.The convex of strip is separated between insurance fixation hole 24 and location notch hole 23
Wall 40 out have enough spaces to accommodate insurance in the lower section of protrusion wall 40.Protrusion wall 40 can guarantee insurance and high pressure
Electric isolution between busbar 5.
The specifically used state of support base 100 is illustrated below, as shown in Figure 5 and Figure 6, support base 100 is set to
The external interface end of the inside of electric machine controller.The structure of electric machine controller include bottom plate 1, be set to it is U-shaped multiple above bottom plate 1
Close busbar 2, capacitor 3 and IGBT board 4.High-voltage busbar 5 divides three parts and connect with IGBT board 4.Support base 100 passes through through-hole 32
It is fixedly connected on the bottom plate 1 of electric machine controller.Herein it should be noted that composite bus bar 2 is a kind of folding for positive and negative busbar
Layer busbar, centre are insulating paper.Since the stray inductance of composite bus bar 2 can be effectively reduced in positive negative busbar laminated construction, into
One step it can reduce calorific value.In addition, high-voltage busbar 5 is common copper bar, it is identical as the effect of cable.Specifically, in motor
Shunting and 4 DC terminal of IGBT board and electricity inside controller, after two terminals of composite bus bar 2 are come in, by six terminals
Hold 3 to be bolted.Direct current is converted to and is exported after AC energy by high-voltage busbar 5 by IGBT board, wherein high-voltage busbar
5 are bolted with the end that exchanges of IGBT board 4.Herein, capacitor 3 can be used as storage when direct current is converted to AC energy
It can device.Because the very great fluctuation process of electric current and voltage can occur during direct current is converted to alternating current, capacitor 3
Effect is exactly to stablize medium voltage, prevents voltage fluctuation is too big from influencing entire transducing process, to guarantee enough electric current output, into
Without dragging down power end voltage.
In the electric machine controller course of work, as shown in Figure 7 and Figure 8, pass through two-phase electrical interface 2 ' and external DC power supply
Connection.Direct current is transmitted to capacitor 3 and IGBT board 4 by composite bus bar 2, and is rectified in IGBT board 4.After over commutation
Direct current become the alternating current of pulse wave form, alternating current is transferred to three-phase electrical interface 5 ' by high-voltage busbar 5, and three-phase electricity connects
It is motor power supply that mouth 5 ', which connects motors,.
Although by reference to preferred embodiment, invention has been described, the case where not departing from the scope of the present invention
Under, various improvement can be carried out to it and can replace component therein with equivalent.Especially, as long as there is no structures to rush
Prominent, items technical characteristic mentioned in the various embodiments can be combined in any way.The invention is not limited to texts
