The invention relates to the technical field of electric vehicles, in particular to a motor mounting structure design method, a motor mounting structure and a vehicle. The motor mounting structure design method comprises the following steps: designing an auxiliary frame according to the volume of all motors; according to the installation space of the auxiliary frame and the size of the motor, the initial installation position of the motor is determined; determining the initial length and structure of each suspension according to the initial mounting position and weight of the motor and the position of each suspension mounting point arranged on the auxiliary frame; and the length and the structure of each suspension are adjusted until the deviation between the gravity center of the auxiliary frame and the gravity center of the connection whole of the auxiliary frame, the motor and the suspensions is within a set range. According to the scheme, the problems that in the prior art, different power motors and assemblies are adopted for vehicle types with different positions, new auxiliary frames need to be matched and developed, and the investment of development and verification work, period and cost is large can be solved.

    本发明涉及电动汽车技术领域,具体涉及一种电机安装结构设计方法、电机安装结构及车辆。该电机安装结构设计方法,包括以下步骤:根据所有电机的体积,设计副车架;根据副车架的安装空间和电机的体积,确定电机的初步安装位置;根据电机的初步安装位置和重量,以及副车架上设置的各悬置安装点位置,确定各悬置的初步长度和结构;调整各悬置的长度和结构,直至副车架的重心与副车架、电机和悬置连接整体的重心偏差在设定范围内。本方案能够解决现有技术中针对不同定位的车型上采用不同的动力电机及总成,存在需匹配开发新副车架,开发验证工作、周期、成本都投入大的问题。
