Abstract

The invention discloses a weight detection mechanism, a safety seat and a weight detection method, and relates to the technical field of seat weight detection. The weight detection mechanism comprises a detection main body, an elastic pressing sheet, a supporting part and a detection sensor. A detection groove is formed in the detection main body, and the elastic pressing sheet is arched and is arranged in the detection groove. The supporting part is used for bearing a child, is slidably connected to the detection groove, and can be pressed into the detection groove when being pressed by an external force so as to press the elastic pressing sheet. The detection sensor is arranged in the detection groove, corresponds to the elastic pressing piece and can detect the deformation quantity of the elastic pressing piece when the supporting part presses the elastic pressing piece so as to output a weight signal. The weight detection method is applied to the weight detection mechanism, and the weight detection mechanism can be applied to the safety seat and has the advantages of being simple in structure and low in cost.

Description

technical field [0001] The invention relates to the technical field of seat weight detection, in particular to a weight detection mechanism, a safety seat and a weight detection method. Background technique [0002] When using safety seats, children of different weights need to adopt different installation methods and seat belt restraint methods. However, the existing weight detection method uses a plurality of strain gauges to measure the weight together, and the cost is relatively high. [0003] In view of this, it is particularly important to develop and design a weight detection mechanism, a safety seat and a weight detection method that can solve the above technical problems. Contents of the invention [0004] The object of the present invention is to provide a weight detection mechanism, a safety seat and a weight detection method, all of which have the characteristics of simple structure and low cost. [0005] The invention provides a technical solution: [0006]...
