Abstract: The invention relates to a combined ceiling fan and light fixture, wherein the roots of the plurality of blades of the ceiling fan are respectively fixedly connected to a plurality of rotating components correspondingly arranged on the impeller. Each rotating component comprises a synchronous wheel, and all synchronous wheels are distributed on the bottom of the impeller with the wheel center of the impeller as the array center. Any two adjacent synchronous wheels are connected to each other by a swinging rod so that all the synchronous wheels move in the same direction with the corresponding blades. At least one swinging rod is connected with a spring for pulling the swinging rod back in the opposite direction of the centrifugal force of the blade to drive all the blades to be synchronously folded on the top of the impeller when the motor stops. The blade retraction mechanism of the invention has the advantages of high transmission precision, good operational stability, low noise and low cost.

Abstract: A vehicle side pillow assembly includes: a connection bar, two ends of which being disposed with first and second side pillows having opposite pillow surfaces; and first and second installation parts for installing the vehicle side pillow assembly onto two insertion rods of a vehicle headrest. The first and second installation parts are arranged in mirror symmetry and movably connected to the connection bar. The connection bar is disposed with several spaced engagement slots along an axial direction thereof. The first and second installation parts are respectively disposed with first and second engagement portions matching the engagement slots. The first and second engagement portions are capable of being engaged with or separated from the engagement slots, so that the first and second installation parts are fixed at a position corresponding to the insertion rods. The vehicle side pillow assembly is convenient to use and has the characteristics of being convenient for disassembly, installation and storage.
