Title:
MOVABLE BASE AND ELECTRIC APPLIANCE
Document Type and Number:
WIPO Patent Application WO/2023/174273
Kind Code:
A1
Abstract:
A movable base (100) and an electric appliance. The base (100) comprises a base body (110), roller mounts (120), rollers (130) and driving devices (140). The roller mounts (120) are pivotally mounted on the base body (110). The rollers (130) are rotatably mounted on the roller mounts (120). The driving devices (140) are used for driving the roller mounts (120) to swing relative to the base body (110), so that the rollers (130) move towards or away from the base body (110), thereby adjusting the distance between the base body (110) and a bearing surface. The base (100) can not only support the movement of an electric appliance by means of the rollers (130), but can also adjust the distance between the base body (110) and a bearing surface (the ground) by means of the driving devices (140), thereby preventing the electric appliance from skewing.
