Abstract: A shock absorbing and height adjusting structure includes an inner tube, a lower piston assembly and an upper piston assembly. The inner tube includes an upper end, a lower end opposite to the upper end, and an inner space for accommodating a gas. The lower piston assembly includes a lower piston movably inserted into the inner tube, and a lower passage disposed at the lower piston. The upper piston assembly includes an upper piston movably inserted into the inner tube. When the lower passage is opened, the lower piston is moved relative to the lower end, and when the upper piston is forced, the upper piston has movement relative to the upper end toward the lower end to compress the gas.

Abstract: An electric vehicle includes a carrier, at least one wheel assembly, a driving module and a controlling module. The carrier is for carrying an user. The wheel assembly is disposed at the carrier and includes a wheel. The driving module includes a motor disposed at the wheel assembly. The driving module is for switching the motor and includes a sensing unit and a microprocessor. The sensing unit is electronically connected to the motor to detect at least one characteristic of the motor. The microprocessor is electronically connected to the motor. The microprocessor determines whether a predetermined conduction is satisfied according to the characteristic of the motor. When the predetermined conduction is satisfied, the motor is turned off by the microprocessor.

Abstract: An electric vehicle includes a carrier, a free-wheel unit, a foot-wheel unit, a driving unit, a first angle-detecting unit and a micro processing unit. The carrier is for supporting a user. The free-wheel unit is disposed at one end of the carrier. The foot-wheel unit is disposed at the other end of the carrier. The driving unit is disposed at the free-wheel unit or the foot-wheel unit, and is for providing a power to the electric vehicle. The first angle-detecting unit is disposed at the free-wheel unit or the carrier, and is for detecting a swinging status between the free-wheel unit and the carrier so as to provide a swinging signal. The micro processing unit is signally connected to the driving unit and the first angle-detecting unit. When the swinging signal achieves a predetermined condition determined by the micro processing unit, the driving unit is turned on.
