  • Patent number: 10800485
    Abstract: The present invention relates to a battery-integrated driver for an electric bicycle, and more specifically, related to a driver capable of changing an ordinary bicycle to an electric bicycle. The driver is installed in a hub on the back of a general bicycle and can be housed inside the hub without an external power connection. Thus, a user can easily assemble an electric bicycle and use it conveniently. The battery-integrated driver includes: a wheel hub (H); a rear side chain support (C) and a saddle support (S) of a bicycle which are coupled to each other at the wheel hub (H); a hub (30) provided in the wheel hub (H) and coupled to a wheel rim through spokes, wherein a tire is installed on the wheel rim; a driver (A) provided in the hub (30) and including an electric motor (660), wherein the electric motor (660) supplies electric power to rotate a wheel; and a battery provided in the driver (A) in a detachable manner and driving the electric motor (660).

  • Patent number: 10752319
    Abstract: A driving control method for an electric bicycle includes: a starting step of supplying the electric power to the electric motor (41) of the electric driving unit (40) and the driving control unit (80) and making the electric bicycle ready to move using the electric power upon a start signal; a constant speed driving step of moving the electric bicycle at a constant rotational speed under the control of the electric driving unit (40), regardless of the pedaling power is provided; a constant speed driving releasing step of automatically discontinuing the constant speed driving step; and a slope skidding prevention step of preventing the electric bicycle from being pushed, in a moving direction or in an opposite direction to the moving direction when the electric bicycle starts and stops on a slope by applying a high load and a counter electromotive force to the electric driving unit (40) and the electric motor (41).

  • Patent number: 7490804
    Abstract: A mount system attaches a monitor to a support base such as a table or wall and is able to reposition the monitor through one or more motorized action. In particular, the mount system includes a motor to tilt the monitor. The mount system includes a mount plate that is adapted to attach to the back side of the monitor. The mount plate may be pivotably coupled to a housing at a first pivot point or axis so that the mount plate may pivot along the first pivot point relative to the housing. A shaft is provided between the mount plate and the housing. The shaft has a proximal end and a distal end. The distal end is pivotably coupled to the mount plate and the proximal end is coupled to a motor, and as the motor is activated, the distal end extends or retracts relative to the housing such that the mount plate extends or retracts relative to the housing.

  • Publication number: 20080149789
    Abstract: A motorized mounting system includes a first portion and a second portion where the first portion is adapted to attach to a mounting surface such as a ceiling or wall, and the second portion is adapted to couple to the back side of a monitor such as a plasma or LCD TV. The second portion has a hinge bracket that attaches to the back side of the monitor. The hinge bracket is mechanically couple to a first motor where activation of the first motor causes the hinge bracket to tilt the monitor. The second portion is mechanically coupled to a second motor where activation of the second motor causes the second portion to swivel relative to the first portion. The motorized mounting system can be controlled by a remote control the tilt and swivel the monitor.

  • Publication number: 20070279851
    Abstract: A flexible enclosure is adapted to enclose one or more motorized actuators in a mounting system. The mounting system is designed to adjust the viewing angle of a flat panel television or monitor. The flexible enclosure has a proximal end and a distal end. The proximal end may be coupled to a base plate that is adapted to couple to a wall. The distal end of the flexible enclosure may extend and may swivel and/or tilt in a sliding manner to follow the movement of the monitor.
