Title:
PIEZOELECTRIC POWER GENERATION APPARATUS AND SMART HOME DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/011758
Kind Code:
A1
Abstract:
A piezoelectric power generation apparatus. Before trigger members (50) rotate to preset positions in preset directions, a second end (54) of each trigger member is connected to a first pressing plate (42) to limit the first pressing plate (42) to move downwards in a first direction (X), so that kinetic energy of a button (20) during downward movement can be converted into elastic potential energy of a first elastic member (46) during compression. When the trigger member (50) rotates to each preset position in each preset direction, the second end (54) can be completely separated from the first pressing plate (42), so that the elastic potential energy of the first elastic member (46) can be converted into the kinetic energy of the first pressing plate (42) during downward movement. In this way, it is ensured that in different scenarios and different user operations, the elastic potential energy accumulated by the first elastic member (46) is identical, and the pressure borne by a piezoelectric element (30) is identical, thereby ensuring that the electric quantity generated by single deformation of the piezoelectric element (30) can be kept consistent. In addition, the first elastic member (46) quickly restores, the first pressing plate (42) instantly completes an action, and the time is short and stable, thereby ensuring that the electric quantity generated by the piezoelectric element (30) can meet an electric power consumption demand. Also provided is a smart home device.
