Abstract: An assembling type rotor structure of brushless motor can be applied both in outer stator/inner rotor motor and inner stator/outer rotor motor. The rotor structure includes a rotor's main body having a plurality of ribs made of non-permeable material and a plurality of embedded small teeth capable to be disassembled in axial direction. These small teeth are formed by punching and stacking up a plurality of permeable silicon steel sheets, and each of these small teeth has a scoop channel having configuration and size matching those of the ribs of the rotor's main body. In this way, these small teeth of the rotor can be tightly embedded and fitted into the rotor's main body in axial direction but can not be moved in tangential nor in radial directions. Therefore, the rotor structure provides a rather firm fixation. What is more, the containing holes formed between each pair of the adjacent small teeth of embedded type can let the permanent magnets be embedded and fixed therein.

Abstract: A collapsing device for the third wheel of a golf cart includes a fixing base, a wheel frame, and a pin. The fixing base is U-shaped to form an interior hollow for the sleeve to fit in, having an insert groove respectively in each sidewall. The wheel frame has its bottom assembled with a third wheel, and its top provided with a slide groove at opposite sides and a through hole pivotally combined with a sleeve. The pin is inserted in the slide groove, having both ends protruding out of the slide sleeve and its intermediate portion clasped by a spring, which has its other end connected with a cover member fixedly mounted on the wheel frame. Thus, the pin is pulled by the spring and stuck in the upper or the lower insert groove for stabilizing the third wheel in the collapsed or the expanded condition.

Abstract: A parallel mixed power unit includes a storage battery, an electron controlling module, an internal combustion engine with an output shaft, a planetary gear differential device having a shell, at least one planetary gear unit having two planetary gears provided inside the planetary gear differential device and disposed on a planetary arm by a bearing, with the planetary arm fixed on the shell, a solar gear meshed with one of the two planetary gears and fixed with the output shaft of the internal combustion engine, and another solar gear meshed with the other of the two planetary gears and fixed with a transmission shaft. The transmission shaft has one end connected with the output shaft of an electric motor by a rotary transmission device and the other end connected with the output shaft of a load terminal by another rotary transmission device.

Abstract: A combining device provided between a wheel and an axle includes a main body fixed in the center hole of a wheel, a pull handle fitted in the main body, and a combining base secured at one end of the axle. The main body is formed with a hollow interior for the combining base to be inserted therein. The pull handle is fitted around with a spring for pressing down a shaft under the pull handle. The shaft is inserted in the interior of the main body and restricted to stay in a position-limiting section of the combining base positioned in the main body. The main body is provided on top with a deep and a shallow groove formed crossing each other for the pull handle to rest therein through pulling and shifting. Thus, the shaft under the pull handle is controlled to let the wheel engaged and disengaged from or detached from the axle.

Abstract: A golf-cart upper support frame includes an upper and a lower cap, two slide blocks, two movable wings and a band unit. The two slide blocks are movably combined the upper and the lower cap, having respectively a shaft base for a shaft to insert and also in each wing under the shaft base. Each wing has a concave surface in a front side for receiving a club bag. The band unit is combined with the two wings to bind a club bag resting on the two wings adjustable in their locations by the slide blocks so that club bags of various sizes may be carried resting on the upper support frame adjustable in its size. So a club bag carried by the golf cart with the upper support frame might not sway around, even if the golf cart should run on a non-flat rough ground.
