摘要： The present invention discloses an electric vehicle frame having a lower portion and an upper portion. The lower portion includes a base and integral sidewalls. The sidewalls extend from the base to form an open cavity. The upper portion detachably joins to the lower portion such that the upper portion covers the cavity and forms a frame assembly which defines an enclosed chamber therein. The strength of the assembly is substantially greater than the strength of each of the portions prior to being joined. The lower and upper portions are formed of cast aluminum. The present invention further includes a method of assembling an electric vehicle, which includes using the frame and a plurality of subassemblies, and the electric vehicle formed therefrom, particularly in the form of a motor scooter.
摘要翻译：本发明公开了一种具有下部和上部的电动车辆框架。下部包括基部和一体侧壁。侧壁从基部延伸以形成开口腔。上部可拆卸地连接到下部，使得上部覆盖空腔并形成在其中限定封闭室的框架组件。组合件的强度基本上大于在连接之前每个部分的强度。下部和上部由铸铝形成。本发明还包括一种组装电动车辆的方法，其包括使用该框架和多个子组件以及由其形成的电动车辆，特别是以摩托车的形式。

摘要： To efficiently arrange a plurality of batteries in a large-sized electrically-driven vehicle. An electrically-driven vehicle includes a vehicle body frame including a head pipe for supporting a steering shaft, upper frames which project in the vehicle-body lateral direction therefrom and extend in the rearward direction, lower frames, and rear frames which are connected with the lower frames. The vehicle body frame is configured in an approximately U-shape as a whole in a side view. In a space which is surrounded by the vehicle body frame, a plurality of batteries are arranged like stairs in parallel in the vehicle-body longitudinal direction along the approximately U-shape of the vehicle body frame.
摘要翻译：为了在大型电动车辆中有效地布置多个电池。电动车辆包括：车体框架，其包括用于支撑转向轴的头管，从车身横向方向突出并沿着向后方向延伸的上框架，下框架和后框架，较低的帧。车体框架在侧视图中整体上构成大致U字形。在由车身框架包围的空间中，多个电池沿着车体框架的大致U字形在车身纵向方向上平行布置成楼梯。
