Provided is a wheel support structure for a self-propelled electronic device which takes safety into account, by not jumping out vigorously with strong force when a drive wheel protrudes to the exterior. The wheel support structure for self-propelled electronic device is characterized by comprising: a drive wheel which supports and drives a housing on a floor surface; a swinging support unit whichrotatably supports the drive wheel and mounts the drive wheel to the bottom part of the housing so as to be able to swing in a vertical direction about the swinging axle; and a biasing mechanism which includes a biasing member which biases the drive wheel so as to swing downwards, wherein the biasing mechanism biases the swinging support unit downwards by means of the biasing member in a state inwhich the housing is placed on the floor, and the biasing towards the swinging support unit by the biasing member is released in a state in which the drive wheel is not in contact with the floor surface.
本发明提供一种考虑到驱动轮向外部突出时不以强的力快速弹出的安全性的自走式电子设备的车轮支承结构。上述自走式电子设备的车轮支承结构,具备:驱动轮,其在地面上支承壳体并使所述壳体行走;摆动支承部,其可旋转地支承所述驱动轮且以摆动轴为中心而向上下方向可摆动地枢接于所述壳体的底部;以及施力机构部,其包含将所述摆动支承部向下方施力的施力构件,以使所述驱动轮向下方摆动,所述施力机构部构成为:以所述壳体被载置在地面上的状态下通过所述施力构件将所述摆动支承部向下方施力,且在所述驱动轮从地面离开的状态下解除由所述施力构件对所述摆动支承部的施力。
