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, comprising a shell, a transparent cover body, a display, a mainboard and a weighing transducer, wherein the display, the mainboard and the weighing transducer are fixed relative to the shell which is provided with a limit opening, and a support component of the transparent cover body can move up and down without friction relative to the shell through the limit opening; the support component of the transparent cover body is arranged on the weighing transducer, and in the weighing state, the support component contacts theweighing transducer and applies gravity on the weighing transducer. Since an electronic scale is integrated on the portable electronic device, the portable electronic device not only is convenient forweighing but also maintains original functions under the condition that the size of the portable electronic device is changed slightly.

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...
