The invention discloses a solar photovoltaic panel expanding and supporting mechanism for an electric vehicle. The solar photovoltaic panel expanding and supporting mechanism comprises a multi-layer supporting frame mechanism, a vertical supporting mechanism and a rotary fixing mechanism. The main supporting frame is of a rectangular frame structure, the first layer of solar photovoltaic panel is installed on the surface of the top layer of the main supporting frame, a second layer of solar photovoltaic panel supporting frame, a third layer of solar photovoltaic panel supporting frame and a fourth layer of solar photovoltaic panel supporting frame are further arranged in the main supporting frame, and each layer of supporting frame is provided with a layer of solar photovoltaic panel and an expansion driving mechanism. The second-layer photovoltaic panel can be driven by the first expansion driving mechanism to extend leftwards or retract transversely along the main supporting frame, and the third-layer photovoltaic panel can be driven by the second expansion driving mechanism to extend rightwards or retract transversely along the main supporting frame. And the fourth layer of photovoltaic panels can be driven by a third extension driving mechanism to extend upwards or retract along the main support frame in the vertical direction. The solar photovoltaic panel expanding and supporting mechanism has the advantages of being light in overall weight and capable of being conveniently installed on a car roof to be carried and charged.

本发明公开了一种电动车用太阳能光伏板扩展支撑机构，包括：多层支撑架机构、竖起支撑机构和旋转固定机构；主支撑架为矩形框架结构，第一层太阳能光伏板安装在主支撑架的顶层表面，在主支撑架内还设有第二层、第三层、第四层太阳能光伏板支撑架，每层支撑架上分别设置一层太阳能光伏板和扩展驱动机构，使第二层光伏板能够在第一扩展驱动机构的驱动下沿主支撑架横向向左伸出或收缩运动、第三层光伏板能够在第二扩展驱动机构的驱动下沿主支撑架横向向右伸出或收缩运动、第四层光伏板能够在第三扩展驱动机构的驱动下沿主支撑架竖向向上伸出或收缩运动。本发明所涉及的太阳能光伏板扩展支撑机构整体重量轻，便于安装在车顶进行携带充电的特点。
