Publication number: 20160347118Abstract: A bicycle rear wheel quick release structure includes a rear hub, hub connector, quick release holder, quick release bolts and fixing element. Flanked by an end plate and an opening, the rear hub receives a rear wheel transmission member. The end plate has a central hole and first positioning holes surrounding the central hole which corresponds in position to the rear wheel transmission member centrally. Received in the rear hub and coupled to rear wheel transmission member, the hub connector has second positioning holes and an axial post with a fixing hole. The axial post is coaxial with the rear wheel transmission member and penetrates the central hole. Having a coupling hole, the quick release holder is mounted on the end plate and engaged with the quick release bolts inserted into the communicated first and second positioning holes. The fixing element penetrates the coupling hole and the fixing hole.Type: ApplicationFiled: May 4, 2016Publication date: December 1, 2016Inventors: HSIN-LIN CHENG, CHING-CHUNG TENG

Patent number: 9409623Abstract: A bicycle pedal structure capable of triggering auxiliary power includes a base, sleeve unit, crank shaft, pedal cranks and treading force sensing unit. The sleeve unit has first and second sleeves disposed in two openings of the base. The crank shaft is fitted in the first and second sleeves and thus rotatably disposed in the base. The pedal cranks are coupled to two ends of the crank shaft, extend in opposite directions, are substantially perpendicular to the crank shaft, and each have a pedal for rotating the crank shaft under a treading force. The treading force sensing unit has piezoelectric plates disposed on at least the first and second sleeves and above the crank shaft. The bicycle pedal structure is mounted on a bicycle chassis and connected to a driving-controlling system to trigger the driving-controlling system to generate and supply digit modularized auxiliary power to the bicycle pedal structure.Type: GrantFiled: June 8, 2015Date of Patent: August 9, 2016Assignee: MOTIVE POWER INDUSTRY CO., LTD.Inventors: Hsin-Lin Cheng, Ching-Chung Teng
