Abstract: A circular polarized antenna structure is provided, including: an antenna having a main body, a protruding portion, and a stopping portion formed between the main body and the protruding portion; a base; a radiation conductor disposed on an upper surface of the base and having at least a first through hole formed above the via hole; a ground conductor disposed on a lower surface of the base and has at least a second through hole formed below the via hole; solder partially covering an end of the stopping portion opposing the main body and the first through hole; and colloid partially formed on the solder, the radiation conductor, and the upper surface of the base. The antenna penetrates the base, and the stopping portion abuts against the lower surface of the base, such that the antenna can be prevented from dropping due to the impact of an external force.

Abstract: A transmission system for an electric vehicle includes a gearbox which produces different rotation ratio between a drive motor and drive wheels during running of the electric vehicle, a differential which serves to absorb a power of the gearbox to overcome rotation speed difference between the drive wheels, and two wheel axles which are used to deliver the power to the drive wheels from the differential, the gearbox has a housing which is connected to a vehicle frame of the electric vehicle via a universal coupling. When the electric vehicle runs on a bumpy road and makes a turn, the vehicle frame is able to swing up and down and pivot left and right with respect to the gearbox housing, so as to reduce the bounce of the vehicle and dampen the centrifugal force caused tilt or roll of the vehicle, thus improving driving comfort and stability.

Abstract: Disclosed is a circular polarized antenna structure, comprising a main body, a protruding portion and a stopping portion, the stopping portion being formed between the main body and the protruding portion. The circular polarized antenna may be disposed to penetrate through the upper and lower surfaces of a base that has a radiation conductor and a grounding conductor disposed thereon respectively, the stopping portion abutting against the lower surface of the base to prevent the main body from coming loose and being detached from the base even if the protruding portion is subjected to a great impact or squeezing pressure caused by an external force coming from the lower surface upwards.

Abstract: A clutch type driving mechanism used in a hybrid powered vehicle is disclosed to include an axle housing mounted at a motor shaft of a motor, a sliding sleeve having a female thread meshed with a male thread of the axle housing, an axle bearing mounted in the sliding sleeve, an input shaft rotatably and slidably supported in the axle bearing with its one end normally kept apart from the axle housing and its other end provided with a gear, and an output shaft meshed with the gear of the input shaft. When the motor is started, the axle housing is driven by the motor shaft to rotate the sliding sleeve, and the sliding sleeve is moved along the axle housing toward the motor due to the effects of inertia, causing friction engagement between the input shaft and the axle housing so that the axle housing can drive the input shaft to transfer rotational motion to the output shaft.

Abstract: Disclosed is an antenna structure, comprising a substrate, an antenna circuit disposed on at least one surface of the substrate, and a circuit unit disposed on the same surface of the substrate having the antenna circuit disposed thereon, or another surface opposite to the surface where the antenna circuit is disposed, wherein the circuit unit at least includes a signal receiving element connected to one end of the antenna circuit, thereby integrating the antenna circuit and the circuit unit on a single substrate and enhancing signal reception.

Abstract: A clutch type driving mechanism used in a hybrid powered vehicle is disclosed to include a motor, a speed reducing mechanism, a hollow shaft, an output shaft and first and second one-way clutches. The motor provides a rotational kinetic energy through the hollow axle to the speed reducing mechanism. The speed reducing mechanism and the output shaft transfer a unidirectional rotary motion to the hollow shaft through the first one-way clutch and the second one-way clutch respectively. Thus, when the output shaft works as a drive shaft, it does not transfer the rotary motion to the speed reducing mechanism, avoiding power loss and allowing transfer of the rotational kinetic energy rapidly and efficiently without bearing much load.
