[0002] With the development of new energy, the proportion of electric vehicles has been increasing in recent years, and electric vehicles are driven by motors. In motor drives, the motor controller converts the DC power supply of the power battery into the AC power supply required by the motor. It is the motor system. The core component of the controller, the main board is susceptible to electromagnetic interference in traditional controllers

The invention discloses a shielding installation mechanism for motor controller mainboards. The mechanism includes an upper cover, a mainboard located under the upper cover, a lower support located under the mainboard and a drive board located under the lower support; the mechanism is installed at the internal of a motor controller; the lower support is fixedly connected to the motor controller through a bolt; the mainboard is fixedly connected to the lower support through the bolt; the upper cover is fixedly connected to the lower support through the bolt; and the mainboard is located in a metal cavity formed through the assembling of the upper cover and the lower support. The mechanism forms the cavity through the assembling of the designed upper cover and the lower support, and the mainboard susceptible to electromagnetic interference can be installed in the cavity, so that the electromagnetic interference of the external on a motor controller mainboard can be effectively reduced, and the normal operation of the motor controller and the driving safety of a whole vehicle can be ensured.
Description
Technical field: [0001] The invention relates to a shielding installation mechanism for a motor controller main board, which belongs to the field of electric vehicle motor control systems. Background technique: [0002] With the development of new energy, the proportion of electric vehicles has been increasing in recent years, and electric vehicles are driven by motors. In motor drives, the motor controller converts the DC power supply of the power battery into the AC power supply required by the motor. It is the motor system. The core component of the controller, the main board is vulnerable to electromagnetic interference in traditional controllers. [0003] Therefore, it is necessary to improve the prior art to solve the deficiencies of the prior art. Invention content: [0004] The present invention provides a shield installation mechanism for a motor controller mainboard in order to solve the problems in the prior art. [0005] The technical solutions adopted in the...
