Battery-free weight induction cushion

Abstract

The invention discloses a battery-free weight induction cushion. The battery-free weight induction cushion comprises a main control panel, an air cushion and a mechanical generating component, a pressure sensor is arranged in the air cushion and connected with the main control panel, and the mechanical generating component is connected with the main control panel. According to the battery-free weight induction cushion, the air cushion is used for supporting a to-be-detected object, the air cushion is extruded due to the effect of the gravity, the change of the pressure in the air cushion is detected through the pressure sensor, the pressure change is converted to the weight through the main control panel, and since the pressure sensor acquires the air pressure change, the air cushion can be randomly placed and does not need to be placed on a flat plane; weight measurement can be realized on non-flat bottom surfaces through the setting of the air cushion, the pressure sensor and the main control panel so that the battery-free weight induction cushion can be widely applied outdoors; and the mechanical generating component is provided so that the dependence on dry batteries can be solved, the conditions of battery replacement and leakage of battery fluid can be avoided, and the practicality is extremely high.

Description

technical field [0001] The invention relates to the field of metering machinery, in particular to a battery-free weight sensing pad. Background technique [0002] Electronic scales for measuring weight are generally made of hard materials, such as tempered glass, metal panels or engineering plastics. This kind of electronic scale has high requirements for the ground where it is placed, and it must be placed on a flat and hard plane to accurately measure the weight; it can be seen that the electronic scale with the above structure is not practical outdoors; and the existing electronic scales need to be configured Dry batteries need to be replaced many times during the service life of the electronic scale, which is very troublesome. It is very inconvenient to leak the battery fluid if it is not used for a long time. Therefore, the present invention provides a battery-free weight sensing pad with strong applicability. . Contents of the invention [0003] In order to solve t...
