| 摘要 |
This invention relates to an accurate load cell for use in mass-produced weighing devices, particularly in low-profile scales incorporating a plurality of load cells. The load cell is made from one flat piece of metal, possibly a single metal stamping, consisting of three structural elements: (1) A flat flexure beam, possibly with a narrow mid-section, on which strain sensors are bonded; (2) A flat U-shaped loaded element attached at its inner mid-section to one end of the flexure beam, with the two leading edges of the U-shaped loading element reaching beyond the mid-point of the middle beam; and (3) A flat mounting element attached at its mid-section to the other end of the flexure beam. The mounting element can also be U-shaped, with the two leading edges of the U-shaped mounting element reaching beyond the mid-point of the middle beam on the outside of the U-shaped loading element.
