Abstract
The invention relates to a controller structure of an electric vehicle motor. The controller structure for the electric vehicle motor comprises a heat radiation housing, heat conduction aluminum strips, power tubes, press bars, rubber bars and a PCB (printed circuit board) and is characterized in that the power tubes are connected to the N-shaped heat conduction aluminum strips in a pressed mode through the press bars. The controller structure for the electric vehicle motor has the advantages that the press bars and the bodies of the power tubes are separated through the elastic rubber bars to prevent the press bars from directly pressing the bodies of the power tubes and meanwhile to avoid invalid connection of the press bars and the power tubes due to size difference of the tube bodies; chips can be well protected from stress damage, the validity of the controller due to the fact that the chips of the power tubes are broken under stress can be reduced; the processing scrap rate of the N-shaped heat conduction aluminum strips can be reduced.
Description
Technical field
The present invention relates to a kind of power tube and ∏ shape heat conduction aluminum strip connected mode, structure and the assemble method of controller for especially a kind of electric vehicle motor.
Background technology
Existing double power tube controller for electric vehicle motor, the connected mode of power tube and ∏ shape heat conduction aluminum strip normally directly is fixed on power tube above ∏ shape heat conduction aluminum strip with screw, in the time of assembling, ∏ shape heat conduction aluminum strip is put into to tool, again power tube is put into above ∏ shape heat conduction aluminum strip, allow the screwed hole of through-hole alignment ∏ shape heat conduction aluminum strip of power tube head, the screw of screwing on.
This connected mode has just determined that the two sides of ∏ shape heat conduction aluminum strip need to process the screwed hole of requirement.Because the screwed hole of these two sides of processing needs twice clamping, mismachining tolerance causes screwed hole to be uneven, and power tube also can be uneven after by screw lock, and pin inserts deep mixed on pcb board, and ∏ shape heat conduction aluminum strip has tilt phenomenon above pcb board.
Put into the radiation shell of hollow after the Reflow Soldering welding when semi-finished product, the end face of ∏ shape heat conduction aluminum strip and radiation shell is fitted by screw lock, because the pin above the pcb board of power tube insertion before is uneven, after heat conduction bar and radiation shell locking, discontinuity above the power tube pin, pin is subject to the easy chip rupture of power tube that stress is large, and whole controller was lost efficacy.
In the running of electric motor car, the stressed power tube solder joint of pin can ftracture because of vibrations, thereby causes whole controller to lose efficacy.
And, because the screwed hole that needs processing on ∏ shape heat conduction aluminum strip is many, the bad management and control of crudy, will cause whole ∏ shape heat conduction aluminum strip to be scrapped as long as there is a hole processing to lose efficacy, and increased quality cost.
Summary of the invention
The objective of the invention is to overcome the deficiency of technology, structure and the assemble method of a kind of electric vehicle motor with controller are provided.This structure can well protect chip to avoid stress rupture, greatly reduces controller because of the stressed inefficacy of breaking and causing of power tube chip, has reduced the scrappage of ∏ shape heat conduction aluminum strip processing.
The present invention is achieved in that the structure of a kind of electric vehicle motor with controller, comprise radiation shell, heat conduction aluminum strip, power tube, press strip, rubber strip, pcb board, it is characterized in that: power tube is by being crimped on press strip above ∏ shape heat conduction aluminum strip, and, by screw lock, the draw-in groove of a swallow-tail form is arranged in the press strip bottom; Be provided with an elastic rubber strip between press strip and power tube body.
The assemble method of the structure of controller for a kind of electric vehicle motor comprises the following steps:
(1) pin of power tube is inserted in the soldering hole above pcb board, cross Reflow Soldering after plug-in unit.
(2) ∏ shape heat conduction aluminum strip is put in the middle of the power tube welded, adjusts position.
(3) rubber strip is buckled in the dovetail groove of press strip.
(4) press strip assembled is positioned at respectively ∏ shape heat conduction aluminum strip both sides, uses screw lock.
(5) again semi-finished product are put into to the radiation shell of hollow, with screw, ∏ shape heat conduction aluminum strip and radiation shell locking laminating are got final product.
Owing to adopting technique scheme, the present invention compared with prior art has the following advantages:
The connected mode of power tube and ∏ shape heat conduction aluminum strip is designed to use the press strip crimping.Separate with elastic rubber strip between press strip and power tube body, avoid the body of the direct crimping power tube of press strip, avoided making due to the size difference of body the phenomenon of press strip and power tube virtual connection simultaneously.In the process of assembling, this crimping has been avoided due to the screwed hole phenomenon of the power pin unbalance stress that causes that is uneven, thereby well protects chip to avoid stress rupture.Greatly reduce controller because of the stressed failure mode of breaking and causing of power tube chip.
In addition, this kind of connected mode allows above ∏ shape heat conduction aluminum strip and needs the screwed hole quantity of processing to greatly reduce, and is more conducive to the management and control of crudy, reduces the scrappage of ∏ shape heat conduction aluminum strip processing.
