The invention relates to the technical field of electric vehicles, and particularly discloses an external range-extending charging device for an electric vehicle. An anti-falling mechanism is arranged in a battery box at the bottom of a chassis, the anti-falling mechanism comprises a mounting shaft fixedly mounted in a mounting groove, a rotatably arranged shaft sleeve and a locking mechanism for locking rotation of the shaft sleeve, and a first baffle and a second baffle are fixedly arranged on the outer side of the shaft sleeve; in the initial state, the first baffle is located at the horizontal position, the second baffle is located at the vertical position, when the battery pack is placed in the battery jar, the edge of the battery pack extrudes the first baffle so as to drive the shaft sleeve to rotate, and after the battery pack is completely placed in the battery jar, the first baffle rotates from the horizontal position to the vertical position so as to drive the shaft sleeve to rotate. At the moment, the second baffle rotates to the horizontal position, and the second baffle extrudes the battery pack to prevent the battery pack from falling off from the battery jar.
本发明涉及电动汽车技术领域,及具体公开了一种电动汽车外置增程充电装置,包括。本发明在地盘底部的电池操内部设置防脱落机构,防脱落机构包括固定安装在所述安装槽内部的安装轴、转动设置的轴套以及锁定轴套旋转的锁止机构,所述轴套的外侧固定设置有第一挡板和第二挡板;初始状态时,第一挡板处于水平位置,第二挡板处于竖直位置,当电池包放置于电池槽内部时,电池包的边沿挤压第一挡板,从而带动轴套旋转,当电池包完全放置于电池槽内部后,第一挡板从水平位置旋转至竖直位置,此时第二挡板旋转至水平位置,第二挡板对电池包进行挤压,防止电池包从电池槽中脱落。
