Problems solved by technology

The electronic scales currently on the market usually use strain gauge resistance sensors, capacitance sensors or semiconductor sensors, which are lighter and more beautiful than mechanical scales; There are also many components in the electronic scale, which is more cumbersome to manufacture, and the volume of the electronic scale will also appear bloated, which affects the appearance and is not easy to transport and carry. Therefore, there is still a need for further improvement.

Abstract

The invention relates to a novel electronic scale which comprises a shell, a pressure-sensitive bedplate, an MCU singlechip connected with the pressure-sensitive bedplate, a control button connected with the MCU singlechip, a display unit connected with the MCU singlechip and a power supply unit of an electronic element, wherein the shell is provided with a loading panel, the pressure-sensitive bedplate is arranged below the pressure-sensitive bedplate in the shell, the MCU singlechip and the power supply unit are arranged in the shell, and the control button and the display unit are arrangedon the shell. By using the pressure-sensitive bedplate as the sensing element, the invention achieves the advantages of light and thin structure, good using effect and durability, and simplifies the elements of the electronic scale. Therefore, the overall structure of the electronic scale is simpler and can be lighter and thinner, and the appearance can be more beautiful.

Description

technical field [0001] The invention relates to a scale, especially a novel electronic scale. Background technique [0002] With the development of science and technology, electronic scales that are different from traditional mechanical structures and measured by electronic components have appeared on the market. When an object is placed on the weighing pan, pressure will be applied to the sensor, and the sensor will deform, thereby changing the impedance. , the changing resistance makes the excitation voltage change, and outputs a changing electrical signal. The electrical signal is processed by the CPU to obtain the corresponding weight data, which is displayed on the display, and the user can read the weighing value. The electronic scales currently on the market usually use strain gauge resistance sensors, capacitance sensors or semiconductor sensors, which are lighter and more beautiful than mechanical scales; There are also many components in the electronic scale, and ...
