Problems solved by technology

[0004] In the invention patent of Chinese patent No. ZL200820035315.X, a mobile phone with a spring scale is disclosed, but what is used in this mobile phone is not an electronic scale, and the measurement accuracy is poor; and it is necessary to install a mechanical spring, hook and scale on the side of the mobile phone. In addition, when weighing, it is necessary to find a hanging member (such as a plastic bag) to carry the weighed item and hang it on the hook, which is very inconvenient to use

Abstract

The invention discloses a portable electronic device capable of weighing, which comprises a casing, a display, a main board and a weighing sensor, wherein the display which is used as a weighing scale is arranged on the weighing sensor and is in contact with the weighing sensor and applies gravity to the weighing sensor in the weighing state. By adopting the invention, electronic scales are integrated on portable electronic devices, and the portable electronic devices can be used for weighing conveniently without influencing original functions under the condition that the volume is slightly changed.

Description

technical field [0001] The invention relates to the technical field of electronic devices, in particular to a weighing portable electronic device. Background technique [0002] Weighing device is a common product in life production. At present, there are some portable electronic scales that can be carried with you. These electronic scales generally include keyboards, displays, main boards, weighing pans and load cells. The main boards include amplification and filtering circuits, analog / digital (A / D) converters and central processing units. After the object to be weighed is placed on the weighing pan, force is applied to the load cell, and the load cell converts the gravity into an analog signal of voltage or current, which is converted into a digital signal by the A / D converter after being processed by the amplification and filter circuit. The digital signal is calculated and processed by the central processor, and the peripheral functions and various interface circuits a...
