A novel self-generating electronic scale

Abstract

A novel self-generating electronic scale comprising a weighing platform (1), a top cover (2), and a bottom cover (3), wherein the top cover (2) is placed on the bottom cover (3), leaving a gap between the side wall of the top cover (2) and the side wall of the bottom cover (3). A first cavity is formed between the top cover (2) and the bottom cover (3), with the weighing platform (1) being mounted on the surface of the top cover (2). The bottom cover (3) is provided with several first through-holes (101), in which weighing sensors (11) are arranged. Several springs (12) are arranged in the first cavity, and the scale is characterized in that a self-generating device (4) and a display module (13) are arranged in the first cavity.The self-generating power device (4) is electrically connected to the display module (13) and serves to supply power to the display module (13), with the weighing sensors (11) also being electrically connected to the display module (13). The self-generating power device (4) comprises a fixed housing (41), a rack (42), a multi-stage gear assembly (43), and a generator (44), wherein the rack (42) and the generator (44) are arranged on two sides within the fixed housing (41). The multi-stage gear assembly (43) is arranged between the rack (42) and the generator (44), with the rack (42) engaging with one side of the multi-stage gear assembly (43). The generator (44) engages with the other side of the multi-stage gear assembly (43), with the fixed housing (41) being secured in the top cover (2).The rack (42) is located inside the fixed housing (41) and the end of the rack (42) is attached vertically to the bottom cover (3).
