5results about How to "Uniform driving force" patented technology

The invention discloses a dustproof and moistureproof flexible driving heat dissipation device which comprises a mounting base, a heat dissipation cover plate, a driving arm and a driving connecting rod, heat dissipation holes are formed in the mounting base, the heat dissipation cover plate is used for covering or opening the heat dissipation holes, and the mounting base is rotationally connected with the heat dissipation cover plate through at least two rotary connecting structures to form a parallelogram structure. The mounting base is in transmission connection with the heat dissipation cover plate through a U-shaped driving arm, one end of the driving arm is fixedly connected with the mounting base, and the other end of the driving arm is fixedly connected with a driving connecting rod. According to the invention, illumination and heat can drive the CNT-Nafion / PE double-layer driver to deform and enable the heat dissipation holes to be opened or closed, and the projection of the heat dissipation cover plate on the mounting base when the heat dissipation cover plate is opened and the projection of the heat dissipation cover plate on the mounting base when the heat dissipation cover plate is closed can completely cover the heat dissipation holes. A macroscopic large-amplitude bending stroke can be generated by using extremely small temperature change, and the opening degree requirement of opening of a heat dissipation channel is met.

The application specifically relates to the technical field of household appliances, and particularly relates to a sweeper, which comprises a base provided with a rolling brush cavity and a battery cavity on a side close to the ground, the rolling brush cavity and the battery cavity are adjacently arranged along a first direction; a rolling brush mechanism is movably installed in the rolling brush cavity; an installation cavity is arranged on a side of the base far from the ground and between the rolling brush cavity and the battery cavity; the installation cavity is in communication with the rolling brush cavity; a driving mechanism is arranged in the installation cavity; a driving end of the driving mechanism extends into the rolling brush cavity and is connected with the rolling brush mechanism; under the driving effect of the driving mechanism, the rolling brush mechanism moves along a third direction. The driving mechanism is directly arranged in the installation cavity, the space of the base is fully utilized, the space utilization rate is improved, and the overall volume of the transmission mechanism can be reduced. The volume of the driving motor and the transmission mechanism is large, the compact layout of the sweeper in the longitudinal height can be reduced, and the thickness of the sweeper can be controlled within a certain range.
