Abstract: The washing machine has the function of automatic lifting castor movement, which is of great significance for cleaning the bottom of the washing machine conveniently, moving the washing machine safely and conveniently, elderly-oriented. Based on the goal of providing users with a simple, convenient, durable and reliable washing machine moving solution, an automatic lifting castor mobile device has been developed. The device has designed a set of casters for mobile washing machines. Through precise calculation of the running track of the casters, theoretical calculation of motor torque, simulation, a large number of reliability tests and user experience, it has innovatively designed a washing machine with motor gear variable speed transmission, inching control in place, lever drive lifting, universal wheel movement, which can easily move the washing machine through automatic lifting casters, it has solved the industrial problem of heavy machinery and difficult handling in the drum washing machine industry, and improved the aging of washing machine products.
