Patent number: 11764592Abstract: A charging device adapted to charge a mobile device includes a fixing base, a charging arm and a restoring member. The charging arm has a first arm end and a second arm end opposite to each other. The first arm end is pivotally connected to the fixing base. During a process of the mobile device docking with the second arm end of the charging arm, the charging arm is adapted to pivotally rotate relative to the fixing base to a docked position corresponding to the mobile device. The restoring member extends along a central axis and is connected to the fixing base and the charging arm. The restoring member provides an elastic potential energy to the charging arm, such that when the mobile device moves away from the charging device, the charging arm is moved from the docked position to an original position by the elastic potential energy.Type: GrantFiled: July 14, 2021Date of Patent: September 19, 2023Assignee: PEGATRON CORPORATIONInventors: Hsin-Lin Chuang, Wen-Chang Chuang

Patent number: 11652354Abstract: A charging device adapted to charge an automatic moving device includes a case, an electricity supply end, a baffle, an arm below the baffle, a blocking assembly on the arm, and a follower. The automatic moving device includes a driving part and an electricity reception end. The case has an opening. The baffle is pivotally connected to the case to cover or expose the opening. The arm has a fixed end and a free end. The blocking assembly is located at an inner side near the opening and movably located on a rotating path of the baffle. The follower is disposed on the free end. When the driving part approaches the opening, the follower moves away from the driving part to drive the blocking assembly to leave the rotating path. The automatic moving device pushes away the baffle, so that the electricity reception end docks with the electricity supply end.Type: GrantFiled: April 8, 2021Date of Patent: May 16, 2023Assignee: PEGATRON CORPORATIONInventor: Wen-Chang Chuang

Patent number: 10907709Abstract: A telescopic adjuster including first and second linear actuators, a connecting platform and first and second telescopic levers is provided. The first linear actuator includes a first screw and a pair of first fixing rings. The first fixing rings are arranged at two respective ends of the first screw. The second linear actuator includes a second screw and a second fixing ring. The second fixing ring is arranged at the end of the second screw, relatively away from the connecting platform. The first and second linear actuators are arranged on the connecting platform in parallel. The first screw pushes the connecting platform to move along the first screw, and the first fixing rings limit a movement of the connecting platform. The first and second telescopic levers are coaxially arranged.Type: GrantFiled: June 12, 2019Date of Patent: February 2, 2021Assignee: PEGATRON CORPORATIONInventors: Pei-Ying Tsai, Shih-Wei Hung, Wen-Chang Chuang

Patent number: 10907706Abstract: The telescopic adjuster includes a telescopic rod assembly, a driving unit, and a chain. The telescopic rod assembly includes a fixed tube and a driving tube, where the fixed tube is sleeved over the driving tube or the driving tube is sleeved over the fixed tube, the fixed tube is fixed to a housing, and the driving tube can extend or retract relative to the fixed tube. The driving unit includes a first motor and a first gear, where the first motor is configured to drive the first gear. The chain has one end wound around the first gear and the other end fixed to a top end of the driving tube. When the first motor drives the first gear to rotate, the first gear drives the chain to push or pull the driving tube so that the driving tube extends or retracts relative to the fixed tube.Type: GrantFiled: February 26, 2019Date of Patent: February 2, 2021Assignee: PEGATRON CORPORATIONInventors: Ci-Hong Cai, Shih-Wei Hung, Wen-Chang Chuang
