  • Patent number: 11926389
    Abstract: A tilting vehicle includes a frame unit, a tilting mechanism and two front wheels. The frame unit includes a head tube extending generally along an up-down direction, and a main frame detachably connected to the head tube. The tilting mechanism includes one crossbar pivotally connected to the head tube and extending along a left-right direction, and two connecting rods extending along the up-down direction, being opposite to each other along the left-right direction, and being pivotally connected to opposite ends of the one crossbar, respectively, such that the connecting rods are movable along the up-down direction relative to the head tube. The front wheels are rotatably mounted to the connecting rods, respectively.

  • Publication number: 20230339560
    Abstract: A motorcycle windshield structure includes a windshield support frame set that supports a windshield and includes a vehicle body mounting frame seat unit, a sliding frame unit on the vehicle body mounting frame seat unit, and a power unit driving the sliding frame unit to slide. The vehicle body mounting frame seat unit includes a slide rail mounting frame having first and second guide roller sets. The sliding frame unit includes slide rails connected to the slide rail mounting frame and a sliding frame slidable along the slide rails. The power unit includes a power motor and first and second control cables respectively wound around the first and second guide roller sets. The power motor and the first and second control cables define, respectively, a raising stroke and a lowering stroke for the windshield, which are arranged, in a parallel manner, in a vehicle left-right direction.

  • Publication number: 20230135878
    Abstract: A wireless apparatus of an electric motorcycle is assembled to a body of the electric motorcycle and has a receiver, a front wheel tire pressure sensor, and a rear tire pressure detector. The receiver is disposed at and extends out from one of a left side and a right side of a frame of the body. The front wheel tire pressure sensor and the rear wheel tire pressure sensor are disposed at a front wheel and a rear wheel of the body, respectively, and communicate with the receiver via wireless communications. Wherein, the receiver is located aside to prevent shielding effect caused by a battery of the body, thereby enhancing signal quality to allow the receiver to stably receive signals from the front wheel tire pressure sensor and the rear wheel tire pressure sensor.

  • Publication number: 20220340232
    Abstract: The present invention provides a shift control device of a vehicle mounted to a body of a vehicle and having a gearbox, a shift actuator, a base, a gearshift lever, and a gearshift detector. The gearshift lever is disposed on the base. The gearshift detector is electrically connected to the shift actuator. The gearshift lever has a shift pedal, the shift pedal has a pivot portion, and the shift pedal is connected pivotally to the base by the pivot portion. The gearshift detector has a rotating element, and the rotating element is rotated coaxially with the pivot portion of the shift pedal. In the shift control device of a vehicle of the present invention, a signal wire will not be wrapped with other components, so transmission errors of mechanisms are reduced, and the structure is simple.

  • Patent number: 8590656
    Abstract: Disclosed is a battery holding structure of a two-wheeled vehicle. The two-wheeled vehicle includes a frame and a saddle. A storage box is arranged under the saddle. A power unit is arranged under the storage box. The frame is provided with a battery mounting seat. The storage box has a front end forming a shielding section. The shielding section forms a maintenance opening corresponding to the battery mounting seat. The battery mounting seat receives therein a battery to have the battery located within the range of the maintenance opening. To maintain the battery, it only needs to lift the saddle and remove the maintenance cover that covers the maintenance opening to allow the maintenance of the battery to be carried out. This simplifies the maintenance operation of the battery and also simplifies the maintenance of a nozzle of an air intake system provided for an internal combustion engine.
