The electric baby carriage comprises a chassis fixing plate, a pair of parallel sliding rails are fixed to the two sides of the top face of the chassis fixing plate respectively, the upper portions of the pair of sliding rails are each provided with a long-strip-shaped sliding block in a sliding mode, a rack is further formed on the top face of one sliding block, and the rack is connected with the rack. A bearing seat is further fixedly installed at one end of the sliding rail where the sliding block provided with the rack is located, the bearing seat extends to the position over the sliding block, a gear is rotatably arranged on the bearing seat, the gear is meshed with the rack, and a gear shaft of the gear extends out of the bearing seat and is fixedly provided with a hexagon bolt. Aiming at the defect that the electric baby carriage cannot be used by children with different heights, the invention develops a deformation mechanism which is matched with the slide rail, the slide block and the gear, the length of the body of the electric baby carriage is adjusted through the relative displacement between the slide rail and the slide block, and the electric baby carriage is clamped through the locking bayonet lock, so that the electric baby carriage is simple in structure and convenient to use, and the safety is ensured.

    本发明为一种底盘可伸缩的电动童车,包括底盘固定板,底盘固定板的顶面两侧分别固定有一对互相平行的滑轨,一对滑轨的上部均可滑动的设置有一个长条状的滑块,其中一个滑块的顶面上还成型有齿条,成型有齿条的滑块所在的滑轨的一端还固定安装有一个轴承座,轴承座延伸至滑块的正上方且轴承座上可转动的设置有一个齿轮,齿轮与齿条啮合,齿轮的轮轴伸出轴承座且固定有六角螺栓。本发明针对电动童车不能满足不同身高的儿童使用这个缺点,研发了一个滑轨、滑块和齿轮相配合变形机构,通过滑轨和滑块之间的相对位移,从而调节电动童车的车身长度,并通过锁定卡销卡紧,不仅结构简单、使用方便,更保证了安全性。
