Weighing scale with foot shape and foot length measuring function

Abstract

The invention discloses a weighing scale with a foot shape and foot length measuring function. The weighing scale comprises a weighing scale body and a bearing plate, wherein the bearing plate is horizontally arranged on the weighing scale body. A PCB (Printed Circuit Board) is horizontally arranged on the bearing plate, and a plurality of light sensitive tubes which are longitudinally and horizontally arranged are arranged on the PCB. A light insulation cover supported on the bearing plate is also covered outside the PCB, and a plurality of through holes corresponding to the light sensitive tubes one by one are formed in the light insulation cover. The light sensitive tubes are positioned in the through holes. The weighing scale has the advantages of simple structure, convenience in use and long service life.

Description

technical field [0001] The invention relates to a weight scale, in particular to a weight scale with the function of measuring foot shape and length. Background technique [0002] At present, from the perspective of the disclosed patented technology and the use of relevant departments, the principles of measuring the shape and length of the foot can be roughly divided into two categories. [0003] 1. Ultrasonic measurement. The method is to use a position limit block for the heel. When the heel leans against the micro switch of the limit block, the ultrasonic emitting unit located at the front of the foot is triggered to emit ultrasonic waves to the toes, and the length of the feet is calculated from the time of the ultrasonic waves reflected from the toes. [0004] The fatal shortcoming of this method is that ultrasonic scattering characteristics often cause mismeasurement, and the error caused by close-range ultrasonic measurement is very large. This scheme is a failed m...

AI Technical Summary

Problems solved by technology

[0004] The fatal disadvantage of this method is that ultrasonic scattering characteristics often cause mismeasurement, and close-range ultrasonic measurement causes large errors. This solution is a failed measurement solution

The compartment is easy to touch the foot of the person under test and cause injury

[0007] 2) When measuring, the trouser legs are easy to cause mismeasurement and affect the accuracy

[0008] 3) This solution cannot measure the shape of the foot, and the extension and development of the technology are limited

[0009] And, also do not have any kind of weighing scale to have the measurement function of foot shape foot length at present
