Background technology
At present, the histological structure of high power electric vehicle motor controller generally adopts form of sleeve, and power tube is installed on the ∏ type radiator, radiator again by screw on the aluminium section bar shell.The controller of this structure mainly exists heat radiation bad, the drawback of water proofing property, resistance to vibration difference.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of high power electric vehicle motor controller, and this controller is waterproof, shatter-proof not only, and thermal diffusivity is good.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of high power electric vehicle motor controller, it comprises shell, power amplifier board control board and the connecting plate of cuboid, described power amplifier board is provided with the high-power loop feature components and parts of electric motor car, and described control board is provided with electric motor car control weak signal loop feature components and parts; Be interval with two the first separate grooves and second groove on one side of described shell; Described power amplifier board just can be fixedly arranged in described first groove, and described control board just can be fixedly arranged in second groove; The two ends of described connecting plate are fixedly arranged on respectively on described power amplifier board and the control board.Like this,, and control weak signal loop is separated with high-power loop, can weaken the electromagnetic interference of power switch greatly control signal with three layers of assembling design of power amplifier board and control board and connecting plate.
As further improvement of the utility model, described power amplifier board is as substrate by aluminium base, be provided with power tube then on described aluminium base, described power tube is assemblied on the aluminium base by solder reflow, and described aluminium base is close to described first bottom portion of groove by the potting compound sedimentation.Like this, just make power tube very little, thereby the heat-sinking capability of product is provided to the thermal resistance between the shell.
As further improvement of the utility model, the weak signal electric interfaces on the described control board adopts the outlet method of pegging graft, and the large-current electric gas interface on the described power amplifier board adopts the outlet method of binding post.Like this, both guarantee wiring intensity and reliability, effectively reduced manufacturing cost again.
As further improvement of the utility model, described shell is that casting aluminium material is made.
As further improvement of the utility model, on the opposite side surface of described shell, be provided with some radiating ribs.
As further improvement of the utility model, in the housing of described shell, be filled with one of high-temp epoxy encapsulating compound and urethane potting resin at least.Like this, can make shell have good waterproof, protection against the tide, shockproof properties.
The beneficial effects of the utility model are: 1. Du Te three layers of assembling design of three printed boards (connecting plate, power amplifier board, control board) upper, middle and lower will be controlled the weak signal loop and separate with high-power loop, weaken the electromagnetic interference of power switch to control signal so greatly; 2. power tube is assemblied on the aluminium base by reflow soldering, and aluminium base is close to the shell inner cavity bottom by the potting compound sedimentation, so just makes power tube very little to the thermal resistance between the shell, thereby has improved the heat-sinking capability of product; 3. the weak signal electric interfaces adopts the outlet method of connector, and big electric current (power line, ground wire, phase line U, V, W) electric interfaces adopts the outlet method of binding post.Like this, both guarantee wiring intensity and reliability, effectively reduced manufacturing cost again; 4. shell adopts casting aluminium material, and housing has enough heat radiation bottoms and heat radiation gusset, and product has goodish heat-sinking capability like this; 5. filled high-temperature epoxy encapsulant or urethane potting resin in the controller shell chamber, product has goodish waterproof, protection against the tide, shockproof properties like this.
