Abstract: A vehicle lamp device includes an outer frame defining an accommodation space, a light shaping frame, a light-emitting unit, and a light distributing cover. The light shaping frame divides the accommodation space into scattering zones, having first and second light shaping regions spaced apart from each other. The light-emitting unit includes light-emitters aligned with the scattering zones. The light-emitters have first and second light-emitting modules for emitting light towards the first and second light shaping regions. The light distributing cover has lens portions aligned with the scattering zones, and allow illumination of light. Each lens portion has a first lens section that is aligned with the light shaping region of the respective scattering zone, and a second lens section that is aligned with the second light shaping region of the respective scattering zone. The first lens section has a lens curvature different from that of the second lens section.

Abstract: A power generating wheel rim device includes a wheel rim body, a power generating mechanism, a cover mechanism, and a circuit mechanism. The wheel rim body includes a central plate and a central slot recessed into the central plate. The power generating mechanism is embedded in the central slot and is operable to be driven by the wheel rim body to rotate and to generate electricity. The cover mechanism covers the power generating mechanism, is mounted to the central plate of the wheel rim body, and includes an air permeable passage structure that is annular and disposed along a periphery of the cover mechanism and that is in 10 spatial communication with an external environment and the central slot. The circuit mechanism is mounted in the cover mechanism and is electrically connected to the power generating mechanism for converting alternating current of the electricity generated into direct current.

Abstract: A power generating device is adapted to be mounted to a rotatable object, and includes a housing adapted to be fixedly mounted to the object, a rotor module fixedly and coaxially mounted to the housing along an axial line that is substantially horizontal, a stator module mounted to the housing and rotatable relative to the housing about the axial line, and a counterweight module fixedly mounted to the stator module. A center of gravity of the counterweight module is located below the axial line. When the object rotates, the rotor module is driven to rotate relative to the stator module which does not rotate with the rotor module due to a force of gravity of the counterweight module, and one of the rotor module and the stator module generates electric power according a magnetic field provided by another one of the rotor module and the stator module through electromagnetic induction.

Abstract: A fuel tank cap includes a seal cap body and a detaching-proof unit. The cap body has a handheld wall and a surrounding wall that extends from the handheld wall and that is formed with an engaging groove. The detaching-proof unit includes a ring sleeve member and a connection member. The ring sleeve member has an outer ring wall that surrounds the surrounding wall, and a resilient wall that extends the outer ring wall and that is engaged resiliently with the engaging groove. The connection member is connected to the ring sleeve member to be connected to a cap installation portion of a vehicle body.

Abstract: An oil tank cap is adapted to be removably engaged with an oil inlet of an oil tank. The oil tank cap includes a cap body that is one-piece, that is plastic, and that includes a cap portion adapted to be disposed outside the oil inlet, and a plug portion extending from the cap portion along a central axis of the cap body and adapted to extend into the oil inlet. The plug portion has a surrounding surface that surrounds the central axis of the cap body, a base surface, an accommodating slot extending through the surrounding surface, and at least one recess formed in the base surface, extending towards the cap portion, and being isolated from the accommodating slot. The oil tank cap further includes a spring strip that has a positioning portion disposed in the accommodating slot, and two abutting portions extending outwardly of the accommodating slot.
