Abstract: A wireless transmission module for transmitting energy or signals includes a first magnetically conductive element, a first coil assembly and a first adhesive element. The first coil assembly and the first magnetically conductive element are arranged along a main axis. The first adhesive element is configured to be adhered to the first coil assembly and the first magnetic conductive element. The first adhesive element is disposed between the first coil assembly and the first magnetically conductive element.

Abstract: A power device of the scooter comprises a motor, an elastic member, and a one-way bearing. The motor is mounted over the rear fork of the scooter footboard and is provided with a transmission shaft on which a drive wheel is mounted. The elastic member is fastened at two ends with the footboard of the scooter for forcing the drive wheel to press intimately against the rear wheel of the scooter. The one-way bearing is disposed on the transmission shaft such that the one-way bearing is received in the drive wheel for providing a one-way clutching effect, thereby enabling the drive wheel to receive the power of the motor in a predetermined manner so as to drive the rear wheel of the scooter. When the motor is stopped, the rear wheel is hauled to rotate on its own.

Abstract: A power device of the scooter comprises a motor and a unidirectional bearing. The motor is mounted in proximity of the rear wheel of the scooter and is provided with an output shaft which is connected with the axle of the rear wheel. The unidirectional bearing is disposed on the axle of the rear wheel to provide a unidirectional clutching effect enabling the rear wheel to receive the power transmission of the motor in a predetermined manner. As the motor is started, the output shaft of the motor drives the rear wheel to turn at a constant speed. As the motor is stopped, the rear wheel in motion is hauled to turn on its own.

Abstract: A device is designed to secure the front tube of the handlebar of a foldable scooter and is formed of a shaft rod, two clamping members, a wrenching rod, a lashing collar, and a stop nut. The device is pivotally fastened between the front tube of the handlebar and the folding mechanism of the foldable scooter. The clamping members are actuated by the wrenching rod to hold and push a press member of the shaft rod to press against the front tube, so as to prevent the handlebar of the scooter from swaying at the time when the scooter is in motion.

Abstract: A backrest folding structure of an electric cart seat is formed of a first tubular member connected to the seat backrest, a second tubular member connected to the seat main body, a retaining member slidably disposed in the first tubular member, and an elastic member disposed in the first tubular member to provide the retaining member with a spring force enabling the retaining member to be partially jutted out of the first tubular member. The first tubular member and the second tubular member are pivoted together such that they are located at an unfolding position at such time when the retaining member is extended into the second tubular member, and that they are located at a folding position at the time when the retaining member is slid back into the first tubular member.

Abstract: A cruise control device of an electric scooter comprises a power unit, a joining member, and a retaining member. The power unit is mounted near the rear wheel of the scooter and is formed of a motor having an output shaft on which a drive wheel is mounted. The joining member is fastened with the power unit and has a joining portion. The retaining member is pivoted with the scooter rear fork and is provided at one end with an actuating portion connected with a steel cable, and at other end with a retaining portion engageable with the joining portion so as to cause the drive wheel to drive the rear wheel at a constant speed. As the steel cable is triggered, the actuating portion of the retaining member is caused to swivel, thereby resulting in disengagement of the retaining portion with the joining portion. The drive wheel thus moves away from the scooter rear wheel.

Abstract: An electric cart is provided with a motor mount for locating securely the motor of the electric cart. The motor mount is formed of a fitting tube, a connection portion extending from the fitting tube, and a fastening ring disposed at the free end of the connection portion. The fitting tube is fitted over the shaft tube in which the axle of two rear wheels of the electric cart is received. The fastening ring is fastened with the motor such that the spindle of the motor is received in the fastening ring.

Abstract: A structure is designed to adjust the distance between seat and handlebar of an electric cart. The structure comprises a fixed base mounted on the seat post, a movable base fastened with the bottom of the seat and pivoted to the fixed base, and a locating member for locating the movable base at a desired position on the fixed base.

Abstract: A device is designed to press the transmission belt of an electric cart and is formed of a pivot set, a first swiveling member, a second swiveling member, a first wheel set, a second wheel set, and an elastic element. The first and the second swiveling members are pivoted with the pivot set such that they are located at two sides of the transmission belt. The first and the second wheel sets are provided with one or more rollers which are pivoted to the first and the second swiveling members. The rollers come in contact with the transmission belt to enhance the transmission effect of the transmission belt. The elastic element provides the first and the second swiveling members with a spring force enabling them to swivel toward the transmission belt.

Abstract: An improved structure for a steering spindle securing device includes a movable fitting element mounted on a steering spindle of a conventional bicycle or scooter and having a notch extending axially along a peripheral wall thereof, one end of the movable fitting element having a generally wedge-shaped press portion for abutting against an inner ring of a bearing of a front head bowl of the bicycle or scooter, an outer annular wall thereof being provided with an outer thread; a generally tubular fixed fitting element having a notch extending axially along the peripheral wall thereof, a retaining hole extending transversely through the notch, and an inner thread for engaging at least a portion of the outer thread on the movable fitting element; and a retaining element that extends through the retaining hole to secure the fixed fitting element on the steering spindle at a predetermined position such that the movable fitting element, when rotated, displaces along the axis of the steering spindle of the bicycle o
