Abstract
The utility model discloses an anti-vibration controller for an electric power steering system, which comprises a radiator box, a mainboard and a power board. The mainboard is fixedly arranged at the bottom of the radiator box, the power board is arranged in the radiator box and located above the mainboard, the power board is electrically connected with the mainboard, and the radiator box is filled with heat conducting materials. The radiator box is filled with the heat conducting materials, and the mainboard, the power board and the radiator box are fixedly connected integrally by the aid of the heat conducting materials, so that the integral controller is higher in vibration resistance. The mainboard and the power board are connected electrically so that reliability and durability are higher and the service life of the controller for the electric power steering system is prolonged.
Description
Technical field
The utility model relates to a kind of electric booster steering system controller, relates in particular to a kind of anti-vibration shape electric booster steering system controller.
Background technology
Electric boosting steering system (EPS) controller is that a collection control that is applied to vehicle is the Electric Machine Control driver of one with power drive, and its input and output power is greater than 200W, and electronic control unit mainly is made up of mainboard and power panel.
In the prior art; Electric booster steering system controller comprises heat radiation box body, mainboard and power panel; Mainboard is fixedly installed on the bottom of heat radiation box body, and said power panel is installed in the heat radiation box body through bracing frame and is unsettled above mainboard, is electrically connected through conductor wire between power panel and the mainboard.Because the restriction in automobile Arrangement of Engine-room space; The volume of requirement electric booster steering system controller can not be excessive, overweight; Simultaneously the environment for use of automobile electronics is quite abominable, and vibration is very serious, and the electric booster steering system controller of said structure is everlasting in the use; Power panel is prone to take place loosening, and the connecting line solder joint between mainboard and the power panel is very easily pulled to be taken off.Therefore, the reliability of electronic control unit is low in the electric booster steering system controller, and durability is relatively poor, causes the useful life of electric booster steering system controller not high.
The utility model content
To weak point of the prior art, the utility model provides a kind of vibrationproof ability strong, and the reliability between the electronic component is high, the compact electric booster steering system controller that durability is long.
The anti-vibration shape electric booster steering system controller that the utility model provides; Comprise heat radiation box body, mainboard and power panel; Said mainboard is fixedly installed on the bottom of heat radiation box body, and said power panel is arranged in the heat radiation box body and is positioned at the top of mainboard, is electrically connected between said power panel and the mainboard; Fill Heat Conduction Material in the said heat radiation box body.
As a kind of preferred version of the utility model, said filling Heat Conduction Material is two-layer, and one deck is the silica gel layer of mainboard and power panel surface-coated; Another layer is for being potted in the epoxy resin layer in the heat radiation box body.
The beneficial effect of the utility model: the utility model is employed in the heat radiation box body and fills Heat Conduction Material; Through Heat Conduction Material mainboard, power panel and heat radiation box body are connected to one; Whole vibrationproof ability is stronger; The reliability that is electrically connected between mainboard and the power panel is higher, and durability is longer, has prolonged the useful life of electric booster steering system controller.
Description of drawings
Fig. 1 is the structural representation of anti-vibration shape electric booster steering system controller.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done explanation in further detail.
Fig. 1 is the structural representation of anti-vibration shape electric booster steering system controller, and is as shown in the figure: anti-vibration shape electric booster steering system controller comprises heat radiation box body 1, mainboard 2 and power panel 3.Mainboard 2 is fixedly installed on the bottom of heat radiation box body 1, and power panel 3 is installed in the heat radiation box body 1 through bracing frame and is unsettled above mainboard, is electrically connected through conductor wire 5 between power panel 3 and the mainboard 2.Embedding Heat Conduction Material 4 in heat radiation box body 1; Heat Conduction Material 4 can adopt heat conductivility epoxy resin or silica gel material preferably; Heat Conduction Material 4 had both played a part to strengthen heat conduction, also mainboard, power panel and heat radiation box body was connected to one simultaneously, had strengthened the vibrationproof ability.
In the present embodiment, it is two-layer filling Heat Conduction Material, and one deck is the silica gel layer of mainboard and power panel surface-coated; Another layer is for being potted in the epoxy resin layer in the heat radiation box body 1.The shrinkage stress of silica gel is little, can protect surface mount elements and the solder joint of connecting line on mainboard 2 and the power panel 3 effectively; Epoxy resin hardness is high, and vibrationproof and anti-damage ability are strong.
