Abstract:
A clutch device includes a sleeve-shaped first drive member, a first seal member, a second seal member, a plug, a second drive member, and a control member. The first drive member, the first seal member and second seal member cooperate to form a sealed chamber filled with hydraulic liquid. The plug divides the sealed chamber into a first chamber and a second chamber, and the plug defines a screw hole and an opening communicating the first chamber with the second chamber respectively. An output shaft is extended from the plug. The second drive member is driven by the first drive member, and includes a screw shaft threadedly engaged with the screw hole of the plug. The control member is configured for covering or uncovering the opening of the plug. The clutch device is used for prevent overload.
Abstract:
An electronic toy includes a main body and a moving device disposed under the main body for moving the electronic toy. The moving device includes a fixing board, a first wheel, a second wheel, and a motor. The first wheel and the second wheel are magnetic. The first wheel is rotatably fixed to the fixing board for supporting and moving the electronic toy. The second wheel is rotatably fixed to the fixing board and facing the first wheel. The second wheel is operable to apply a magnetic torque to the first wheel when rotating relative to the first wheel, so as to rotate the first wheel. The motor is connected to the second wheel for rotating the second wheel.
Abstract:
An energy saving lamp is provided. The energy saving lamp includes a main body, a circuit, an adjusting member, and a shielding device. The circuit includes a plurality of parallel loops, each parallel loop includes at least one light emitting member and a pair of open ends, the adjusting member is rotatably connected to the main body; the shielding device is fixed on the adjusting member; a conductive rod is fixed at the shielding device, and is received in an accommodating hole of the main body; when the adjusting member turns under a twisting force, it drives the shielding device to turn, the conductive rod moves in the accommodating hole to contact different number of the pairs of open ends to close the loops of the open ends, the light emitting members in the closed loops are thus turned on.
Abstract:
A driving device includes a motor, a rotatable shaft rotated by the motor, a driven member, a magnetic material spring, and a power source. The driven member sleeves on an end of the rotatable shaft, and includes an end surface with at least one latching groove defined thereon. The magnetic material spring sleeves the rotatable shaft, and includes a first end fixed to the rotatable shaft and an opposite second end capable of inserting into the latching groove of the driven member. The power source includes two electrodes. The motor and the spring are electrically connected in series between the two electrodes of the power source.
Abstract:
A replica eye includes an eyeball with a light-transmitting area for transmitting light, a resilient film, a driving member, and a transmission mechanism. The resilient film includes a pupil portion and an iris portion surrounding the pupil portion. The pupil portion is in a first color. The iris portion is in a second color other than the first color. The driving member has a shaft. The driving member provides rotating forces to the shaft. The transmission mechanism comprises a rotor fastened on the shaft of the driving member, and a plurality of flexible members in radial arrangement. A first end of each flexible member away from the rotor is fastened on an outer edge of the resilient film. When the driving member rotates the transmission mechanism, centrifugal forces are imparted on the plurality of flexible members, the plurality of flexible members stretches the pupil portion and the iris portion.
Abstract:
A simulated eye includes a spherical cap eyeball, a resilient film, a driving mechanism, and a transmission mechanism. The eyeball includes a plurality of guide arms on an inner surface thereof. The resilient film received in the eyeball includes a pupil portion and an iris portion surrounding the pupil portion. The driving mechanism provides a first driving force and a second force opposite to the first driving force in direction. The transmission mechanism arranged between the driving mechanism and the resilient film includes a plurality of transmission members received and movable in the corresponding guide arms.
Abstract:
A crawling device includes a first end with a first magnet recessed therein, a second end with a second magnet recessed therein, an elastic member disposed between the first end and the second end, a power source module, and a controller. When the first and second ends are supported on a supporting surface, and the controller connects the power source module to the first end and the elastic member, the first magnet extends beyond the first end onto the supporting surface and the elastic member becomes compressed toward the first end. When the elastic member is compressed, and the controller connects the power source module to the second end, the second magnet extends beyond the second end onto the supporting surface and the elastic member returns to the normal state.
Abstract:
A wheel assembly includes a shaft and a pair of wheels rotatably connected to opposite ends of the shaft. Each wheel includes an inner cover, an outer cover connected to the inner cover, and a steering member sandwiched between the inner cover and the outer cover. The steering member includes a motor, a rotating plate, at least two elastic elements equidistant from each other around the inner cover, and at least two pawls rotatably connected to the outer cover. The motor is fixed on the inner cover and includes a rotating shaft. The rotating plate is fixed to the rotating shaft and is driven by the motor to rotate. Each elastic element connects the rotating plate to each pawl. Each pawl extends out of the inner cover by rotation of the rotating plate, thereby changing the radius of the wheel.
