  • Patent number: 11628778
    Abstract: A vehicle-used bracket includes a base body, a clamping assembly and a buffering element. The base body has a main portion, a peripheral wall extended upward from a periphery of a top surface of the main portion, and a connecting portion fastened to a bottom surface of the base body. A periphery of a bottom surface of the connecting portion extends downward to form a limiting structure. The clamping assembly is mounted to the bottom surface of the connecting portion. The clamping assembly includes a screw, a fastening element and a claw. The claw has a fastening piece. A top surface of the fastening piece is arched towards the connecting portion to form at least one protruding block. The at least one protruding block is limited in the limiting structure. The buffering element is mounted between the connecting portion and the clamping assembly.

  • Publication number: 20140117926
    Abstract: A wireless power charger includes a shell, a circuit board, a displacement adjusting device and transmitter coils disposed in the shell. The circuit board has a position detection controller for detecting a position of a charging target placed on the shell. A rack is mounted to the displacement adjusting device for only horizontally rotating along with the displacement adjusting device, or horizontally rotating along with the displacement adjusting device and further sliding linearly along a radial direction. The transmitter coils are positioned on the rack. In use, the displacement adjusting device is controlled by the position detection controller to only horizontally rotate the rack, or horizontally rotate the rack and further linearly slide the rack, so as to bring the transmitter coils closer to a receiver coil of the charging target and realize inductive coupling therebetween for charging the charging target.

  • Publication number: 20130300366
    Abstract: A charger includes a charging body having a base body, two insertion pins apart assembled to a front end of the base body, and at least one USB port equipped in a rear end of the base body. A power plug includes a plug part, a socket part mounted to the plug part and defining two inserting slots, and two electrical terminals located between the socket part and the plug part and each having a pair of contact portions. The plug part has a group of power pins of which one end electrically connects with the electrical terminals and the other end projects outward for plugging in a wall socket. The power plug can be removably attached to the charging body by means of plugging the insertion pins into the corresponding inserting slots to electrically clamp the insertion pin between the contact portions of the corresponding electrical terminal respectively.
