Problems solved by technology
When the size of the vehicle is fixed, the components scattered in various positions of the vehicle occupy the space of the battery, resulting in the battery life failing to meet customer needs; in addition, since each functional module is scattered in the vehicle, the low-voltage communication between modules The signal is also easily disturbed by the external environment and affects the quality of the vehicle

The invention relates to an electric vehicle motor controller structure capable of integrating a plurality of functions. The electric vehicle motor controller structure comprises a heat dissipation substrate, the upper side of which is provided with side plates, and the side plates are used to form an outer contour in the shape of a square, and the upper sides of the side plates are provided with a cover plate. The heat dissipation substrate, the side plates, and the cover plate are used to form a sealed cavity in an enclosed manner, and a separation plate is used to divide the cavity into an upper layer and a lower layer. A MCU function module control panel, an insulation detector, and a CAN function module are disposed on the separation plate, and are disposed in the upper layer of the cavity. A MCU function module, a DCDC function module, and a DCAC function module are disposed on the heat dissipation substrate, and are disposed in the lower layer of the cavity. The electric vehicle motor controller structure is advantageous in that the function modules are integrated in the same housing structure, and the housing is formed by the heat dissipation substrate, the side plates, and the cover plate in an enclosed manner, and therefore the installation space can be saved, the connecting distances among the function modules can be reduced, the connection among the function modules can be facilitated, the signal interferences of the outside on the function modules can be reduced, and the costs of the whole device can be further reduced.
Description
technical field [0001] The invention relates to the technical field of new energy electric vehicles, in particular to a motor controller structure for electric vehicles integrating multiple functions. Background technique [0002] At present, the entire field of electric vehicles has higher and higher requirements for battery life, and OEMs have higher and higher requirements for the weight of the vehicle and the compactness of the layout of the vehicle. The field of new energy vehicles is a new field. Manufacturers started late, and there are certain limitations in technology. Therefore, they currently adopt a separate supply mode. MCU function modules, DCDC function modules, and high-voltage junction box function modules are all supplied independently. The machine manufacturer coordinates the installation and commissioning in a unified manner. When the size of the vehicle is fixed, the components scattered in various positions of the vehicle occupy the space of the batter...
