Description

A kind of controller for electric vehicle board structure of circuit

Technical field

The utility model relates to a kind of board structure of circuit, is specifically related to a kind of controller for electric vehicle board structure of circuit.

Technical background

Current controller for electric vehicle circuit board is generally to adopt individual plates, and along with the development of electric motor car function, controller interior arrangement becomes increasingly complex, often whole system is arranged on a circuit board, certainly will cause board area excessive, take a large amount of spaces, make controller housing bigger than normal, be unfavorable for miniaturization development; Meanwhile, all functional modules all design on a circuit board, may cause the interference between each functional module, affect the stability of controller.

The general straight cutting of power tube on available circuit plate is on circuit board, and the contact area of power tube and circuit board is little, and radiating effect is poor; Adopt common electric wire as power line and the phase line of controller, and be directly welded on controller circuit board, electric wire conveyance capacity is limited, easily cause electric wire heating, directly be welded in addition circuit board upward stability poor, easily come off, components and parts need manually one by one to being inserted on circuit board, cost of labor is high, inefficiency and failure rate high.

Utility model content

The utility model is for overcoming deficiency of the prior art, adopt two structures that circuit board docks up and down, phase line is fixedly connected with copper post with power line, remaining wire harness adopts connector to connect, and components and parts all adopt SMD, the controller volume that solved prior art is large, cost of labor is high, inefficiency and failure rate is high, radiating effect is poor problem, proposes that a kind of controller volume is little, cost of labor is low, efficiency is high and the controller internal circuit plate structure of failure rate is low, good heat dissipation effect.

For achieving the above object, the technical solution of the utility model is:

A controller for electric vehicle board structure of circuit, comprises first circuit board, second circuit board, power tube, copper post, row's pin, arranges seat, it is characterized in that: first circuit board is docked and is connected up and down by row's pin, row's seat with second circuit board; Power tube is directly attached on second circuit board; On second circuit board, have more than 1 copper post, for fixing heavy current circuit.

On described first circuit board, there is row's pin, on second circuit board, have corresponding row's seat simultaneously, or on first circuit board, have row's seat, on second circuit board, have corresponding row's pin simultaneously; On first circuit board, there is connector; Second circuit board is aluminium sheet; In the middle of second circuit board and controller housing, scribble Heat Conduction Material; On first circuit board and second circuit board, components and parts are SMD.

Compared with prior art, the utility model has significant advantage and beneficial effect, is embodied in some:

1, the controller circuitry plate structure that the utility model provides is upper and lower two boards docking, has saved space.

2, the controller circuitry plate structure that the utility model provides is that power tube is directly attached on aluminium circuit board, between aluminium circuit board and controller housing, scribbles Heat Conduction Material, has strengthened the radiating efficiency of the heater elements such as power tube.

3, the controller circuitry panel element that the utility model provides is surface mount elements, can realize mechanical automation production model, reduces manual operation, failure rate is low, and consistency is high.

Accompanying drawing explanation

Fig. 1 is the utility model controller for electric vehicle board structure of circuit schematic diagram;

Embodiment

Specific implementation method of the present utility model is as follows:

As shown in Figure 1, a kind of controller for electric vehicle board structure of circuit, comprises first circuit board 1, second circuit board 2, power tube 3, copper post 4, row's pin 5, row's seat 6, connector 7.

Board structure of circuit of the present utility model is that first circuit board 1 docks up and down with second circuit board 2, by row's pin 5 and row's seat 6, first circuit board 1 and second circuit board 2 are carried out to connection and be fixed up, effectively reduced the area of circuit board, thereby having reduced circuit board takes up space, promoted the miniaturization development of controller, and the components and parts on a circuit board separately, can effectively prevent the mutual interference effect between element by script to adopt two circuit boards.

Power tube 3 adopts SMD, with chip mounter, be directly attached on second circuit board 2, increased the contact area of power tube 3 with second circuit board 2, and second circuit board 2 is aluminium sheet, in the middle of itself and controller housing, scribble Heat Conduction Material, greatly improved the radiating efficiency of power tube 3, on second circuit board 2, have more than 1 copper post 4, be used for being connected and fixed the heavy current circuits such as phase line and power line, prevent the problems such as heating that high-current leading rises, guaranteed the security reliability of controller.

Remove phase line and be connected with connector 7 with other wire harness beyond power line, can install fast, dismantle, can neatly effectively arrange wire harness again, save space; Components and parts on first circuit board 1 and second circuit board 2 are SMD, for mechanical automation production model, have greatly reduced cost of labor, have also reduced the fault of the product that artificial welding causes simultaneously, have improved the consistency of product.

For being one exemplary embodiment of the present utility model; should be understood to is a certain demonstrative example wherein in the protection range of claims of the present utility model; there is the directiveness effect that those skilled in the art is realized to corresponding technical scheme, but not to restriction of the present utility model.
