Abstract

The invention discloses an automobile high-voltage circuit control integrated module. The automobile high-voltage circuit control integrated module comprises a control board and an electronic component unit, and the control board is provided with a weak current layer, a strong current layer and an insulating layer disposed between the weak current layer and the strong current layer, wherein the weak current layer and the strong current layer are arranged in a stacked mode. A low-voltage driving circuit module is integrated on the weak current layer, and a plurality of copper bars are disposedon the strong current layer. The electronic component unit is provided with a plurality of contactors separately disposed on the control board in a positioning mode, and main contacts of the contactors are electrically connected between every two copper bars to form a plurality of working circuits with different functions. Coil driving contacts of the contactors are separately and electrically connected to the low-voltage driving circuit module, that is, the contactors can be closed or disconnected under the control of the low-voltage driving circuit module, so that the working circuits on which the contactors are located are turned on or off. By integrating and fixing all electronic components to the control board, the advantages of miniaturization of size, convenient installation, and low cost of processing and production of a automobile high-voltage circuit control unit are realized.
