電動車可分拆出單輪，以作為單輪車騎行

人：福特汽車

事：電動車的馬達連結在輪子上，把輪子連同馬達一起拆下來，以作為單輪車的「風火輪」。

時：2016/1

地：USPTO

物：專利名稱為「可與汽車結合的自力推進單輪車」

動機：把車停在停車場後，騎著風火輪到汽車不便停靠的地方。

摘要：

當車主將電動車停妥後，從電動車上拔下一個輪子來，馬達系統內附在輪框之中，將電力與資料傳輸數據纜線拆離電動車本體。再從後車箱中取出單輪車之把手椅座組，放在輪子上，接上電力與數據纜線，就成了一輛單輪車。

Note:

The motivation of ford is great that the customer buys a car that gives a self-propelled unicycle as an additional gift. When it is not convenient for parking the car in specific location as crowd, the lord of the car can remove a single wheel from the car and use the single wheel as self-propelled unicycle to ride.

However, the customer may buy a car and a self-propelled unicycle. The customer puts the self-propelled unicycle into the trunk of the car. It is more convenient without removing the single wheel from the car and assembling the self-propelled unicycle.

We finds the ford’s patent US 9211932, and finds patent US 20120217072 as the prior art of the said ford’s patent. It’s funny.

Self-propelled unicycle engagable with vehicle
US 9211932 B1

摘要

A self-propelled unicycle is selectively engaged with a vehicle for use with the vehicle and is selectively disengaged with the vehicle for independent use. The self-propelled unicycle includes a hub and a wheel rotatably coupled to the hub. A motor is supported on the hub and is coupled to the wheel for rotating the wheel relative to the hub. The hub including an engagement feature for selectively engaging and disengaging the vehicle.

  

Electric-Powered Self-Balancing Unicycle With Steering Linkage Between Handlebars And Wheel Forks
US 20120217072 A1

ABSTRACT

A one-wheeled vehicle includes electric motors, a self-balancing system, and steering mechanism, wherein the electric motors and self-balancing system are disposed within the wheel of the one-wheeled vehicle. Side stirrup legs, which have foot pegs suitable for placement of a rider's feet while riding, are pivoted with respect to the wheel forks, such that the side stirrup legs may be rotated backwards and act as a kickstand for the one-wheeled vehicle. The side stirrup legs may be weighted with, for example, one or more batteries may be attached to the side stirrup legs to provide a weight distribution such that the one-wheeled vehicle does not fall forward when parked. A computational resource such as a microcontroller, or microprocessor-based controller, receives input signals indicative of operation of the twist throttle and brake, and responsive thereto produces signals to adjust the tilt angle relative to the acceleration and thereby reduce the need for a rider to lean forward or backwards.

Powered single-wheeled self-balancing vehicle for standing user 

US 20110220427 A1

ABSTRACT

A powered, gyroscopically balanced unicycle device to be used while standing, having leg contact surfaces which are made of a yielding, slightly soft material whose mild friction against the user's legs allows stable, precise control of the device without restraining the legs in any way. In one embodiment a single hubless wheel is driven by a friction drive mechanism which transmits torque from a motor through a drive wheel positioned below the foot platforms and in contact with the inner rim of the wheel. Various structures are provided for supporting the wheel and keeping it in place as it spins; absorbing small vertical movements of the wheel to prevent them from being transmitted to the foot platforms; enabling folding of the foot platforms; and facilitating carrying of the device by hand. Other embodiments are described and shown.
