A back cover ejection structure is applied in an electronic device. The electronic device includes a back cover and a middle frame, the back cover ejection structure can eject the back cover from the middle frame. The back cover ejection structure includes a housing, a moving plate, and a rotating cover. The moving plate is received in the housing and can move in a first direction. The moving plate includes a plate body and a first groove defined in the plate body. The first groove includes a first section, the first section inclined with the first direction. The rotating cover is rotatably connected to the housing. The rotating cover includes a sliding rod slidably received in the first section. The sliding rod can push the rotating cover to rotate when sliding in the first section, causing the rotating cover to eject the back cover from the middle frame.

Device for securing an orientation of photovoltaic panels includes a stem for supporting an array assembly of photovoltaic panels for producing an electrical current when exposed to sunlight. The array assembly also includes eye blades positioned on a side opposite to a photovoltaic panel carrying side. The device further includes a joint interconnecting the stem and the eye blades of the array assembly. The joint includes a hollow horizontal conduit and a bolting mechanism for adjustably coupling the eye blades to lateral ends of the horizontal conduit. A side of each eye blade facing the horizontal conduit carries an eye blade gear that cooperatively meshes with a conduit gear carried at or near a lateral end of the horizontal conduit to secure the array assembly at a predetermined angle relative to a longitudinal axis passing through the stem.

A geared motor, e.g., a gear unit or a bevel gear unit, which is able to be driven by an electric motor, includes a housing part, which is produced by a die casting method, during or after which sliders are moved, in particular pulled out, in respective drawing directions for the demolding, and an input shaft. The housing part includes a channel, demolded in a first drawing direction, in particular, using a first slider, the channel being adapted to extend through the wall of the housing and ending in the interior space region of the gear unit. The drawing direction has a non-vanishing angle in relation to the axis of rotation of the input shaft, its angle in particular amounting to between 5° and 45°, e.g., between 5° and 20°.

A geared motor includes a gear unit having a first intermediate shaft, an input shaft and an output shaft. The gear unit has two connection surfaces set apart from each other to which a device to be driven by the gear unit is connectable to the gear unit, each connection surface having a drilling pattern. The housing part is asymmetrical such that the plane whose normal direction is aligned in parallel with the axis of rotation of the first intermediate shaft and includes the axis of rotation of the input shaft, is no plane of symmetry in relation to the entire outer surface of the housing part and also no plane of symmetry in relation to the housing wall of the housing part. The plane is a plane of symmetry with regard to the two connection surfaces together with their drilling patterns.

A slat angle adjustment mechanism adapted for use with slats of a Venetian blind includes a body shell and a transmission unit. The transmission unit includes a transmission gear set and a retractable member. The transmission gear set has a gear and a screw. A position-limiting hole of the gear corresponds in position to a second through hole of the body shell. The retractable member connects to the extendible segment of the screw and undergoes reciprocating motion along the extendible segment of the screw. Pulling the retractable member from an initial first position of the extendible segment of the screw to a second position of the extendible segment of the screw allows a rib of the body shell to be confined to a limiting portion of the retractable member. Therefore, the slat angle adjustment mechanism is capable of extension, retraction, engagement and fixation.

A driving device for a washing machine includes a motor comprising a stator and a rotor configured to rotate inside the stator, a shaft configured to receive torque of the motor and rotate an inner tub of the washing machine, a planetary gear located at a front end of the shaft and configured to adjust a rotation speed of the inner tub by changing the torque of the motor at a preset reduction gear ratio, and an electronic clutch located between the shaft and the planetary gear and configured to operate to adjust connection and disconnection between the shaft and the planetary gear according to an operation mode change signal of the washing machine.
