The cover of the drive assembly housing, the drive assembly having it, and the vehicle.
This invention discloses a cover plate for a drive assembly housing, a drive assembly having the same, and a vehicle. The drive assembly housing includes a lower housing and a cover plate. The lower housing has a mounting opening, and the cover plate closes onto the mounting opening. The cover plate includes a central arched area and a mounting area. The mounting area is an annular structure surrounding the central arched area and is used to contact and connect with the lower housing. The central arched area includes multiple curved panel areas that arch from the periphery towards the center in a direction away from the mounting opening. The electronic control cover plate of this application, by setting the central arched area and the mounting area, can increase the modulus of the electronic control cover plate and increase its natural frequency to a certain extent. This makes the natural frequency of the electronic control cover plate far away from the external excitation vibration frequency caused by the vibration of the drive motor, thereby reducing the resonance between the electronic control cover plate and the drive motor, reducing vibration and noise during drive assembly operation, and reducing resonance fatigue of the drive assembly structure.

A heat dissipation device for a circuit board and a circuit board
PendingCN122138323AReduce maintenance costslow noisePrinted circuit detailsCooling/ventilation/heating modificationsThermodynamicsMechanical engineering
This invention relates to the field of circuit board heat dissipation technology, specifically to a circuit board heat dissipation device and circuit board. The device includes a fan with a sealing cover at the fan's air inlet. The sealing cover has several first air inlets communicating with the fan's air ducts. Each first air inlet is connected to a heat-conducting module via a delivery pipe. Several heat-conducting modules are used to contact different heat-generating areas of the circuit board to achieve heat exchange, and the heat is dissipated through the fan and delivery pipes. Each heat-conducting module includes a primary heat-conducting unit and several secondary heat-conducting units, each unit being interconnected to form a unified chamber. It can conduct heat to multiple heat-generating areas of the circuit board through multiple heat-conducting modules and dissipate heat through a single fan. The fan has low maintenance costs and produces minimal noise and vibration. Each heat-conducting module can be assembled with an appropriate number of heat-conducting units according to the heat generation range to form a heat-conducting module of suitable volume, achieving appropriate heat conduction and dissipation effects.
