Abstract: An electric generator assembly includes an electric generator, a generator support, and two shock-absorbing units. The electric generator includes a generator housing, and a rotor disposed in the generator housing and defining a central axis. The generator support has two sloped flat surfaces that are inclined to a vertical plane, on which the central axis lies. The sloped flat surfaces are disposed at two opposite sides of the vertical plane and face each other in a transverse direction relative to the vertical plane. Each of the shock-absorbing units is secured to a respective one of the sloped flat surfaces and the generator housing so as to provide a shock-absorbing effect to the electric generator.

Abstract: A gear-shifting mechanism for vehicles has a crankcase, a gearbox and a reserved room. Because the reserved room is formed between a first case of the crankcase and a body of the gearbox, a shift lever can protrude out of the first case and is mounted into the reserved room to connect to a transmission between the crankcase and the gearbox. Besides, the shift lever also can protrude out of a second case to connect to a transmission opposite to the gearbox. As a result, the shift lever can output in two directions, applicable for the gearbox in left or right of the crankcase. An engine connected to the gear-shifting mechanism can be adapted for various vehicles.

Abstract: A cooling system for a generator of a vehicle has an engine, a generator and a wind collection box. The generator has a rotor driven by the engine and a fan synchronously rotating with the rotor. The wind collection box is connected to the generator via a first guiding tube. The fan draws exterior air from the wind collection box and the first guiding tube to allow the exterior air to flow through the generator. Thus, heat in the generator that is mounted in an airtight engine compartment is dissipated.

Abstract: A cooling system for an exhaust pipe of a vehicle has an engine, an exhaust discharging device connected to the engine, a generator driven by the engine and a cooling guide device. Even when the vehicle is idle, the cooling guide device still guides cool air from the generator to the exhaust discharging device to dissipate heat of the exhaust discharging device. Therefore, the heat of the exhaust discharging device is efficiently dissipated.

Abstract: A control structure is provided for a throttle valve of engine. The throttle valve includes a throttle plate arranged inside the valve body and mounted to a control shaft having an end extending outside the valve body and received in a control seat mounted outside the valve body and having a shaft hole seat, a constraint block, a coupling hole seat, and a cable outlet section. A control assembly includes a return spring and a control rocker arm that includes a connection section forming a connection hole to be fit over the control shaft and a cable connection section, a positioning section, and a push section. The control motor is mounted to the coupling hole seat of the control seat and has a driving rod having a front tip section positioned against the push section of the control rocker arm. The control seat lid is secured to the control seat.

Abstract: A vehicle air intake mechanism comprises an air intake duct having an inlet end opening which opens in an axial direction, and a flow-guiding member having an outer surrounding wall that defines a flow channel in fluid communication with the inlet end opening. The outer surrounding wall has first and second end portions that extend in the axial direction. The first end portion of the outer surrounding wall surrounds an inlet end portion of the air intake duct. The first axial end of the outer surrounding wall defines a first end opening that is in fluid communication with the flow channel and that opens in the axial direction. The inlet end opening is disposed between and is spaced apart from first and second axial ends of the outer surrounding wall in the axial direction.
