Technical Field

The present invention relates to the field of drive devices for equipment.

Technical Field

A wheeled device, such as an automobile, aircraft or mechanical device, is propelled by rotation of the wheel in a direction perpendicular to the axis of rotation of the wheel.

In certain specific situations, it is for example necessary to adjust the direction of movement of the device, moving the device with wheels parallel to the axis of rotation of the wheels. If the space for operations in this particular scenario is small, such operations often cannot be accomplished. For example, the steering is realized under the condition that the reserved turning radius is small, or the parking space length is small when the vehicle is parked at the side position.

In order to solve the above problems, many solutions have been proposed. For example, chinese patent No. CN107804300A entitled parking assist device; this patent has solved the problem that the car side direction was parkked.

For another example, chinese patent No. CN206031350U entitled portable automobile shifter, which solves the problem of steering and shifting of automobiles.

Also known as EP3051041a1 is the european patent entitled mobile device for parking a car, which proposes a solution for a mobile device.

The solutions proposed in the above patents all have some technical problems, such as low product integration level, poor portability, low structural reliability, etc.
