pressure sensor for bed

Abstract

The invention discloses a pressure sensor for a bed, which comprises a casing, a sensor body and an A / D circuit board arranged in the casing, the casing includes a mounting seat and a bearing arranged on the top of the mounting seat A pressure plate, the mounting seat includes a base and a side cover surrounding the periphery of the base, the pressure bearing plate is attached to the sensor body, and the horizontal position of the pressure bearing plate is lower than the side cover The horizontal position of the upper end surface of the bed, the pressure bearing plate and the upper end of the side cover form an accommodating and limiting space for the bed foot to be accommodated and limited therein. The base includes a bottom plate, support columns arranged on the bottom plate at intervals around the periphery of the bottom plate, and an annular auxiliary stopper set on the top of the support column. The sensor body and the A / D circuit board are from top to bottom. The lower ones are sequentially fixed on the bottom plate and located in the annular auxiliary limiting piece, and the peripheral edge of the lower surface of the pressure bearing plate is placed on the annular auxiliary limiting piece.

Description

technical field [0001] The invention relates to a pressure sensor, in particular to a pressure sensor for a bed. Background technique [0002] A pressure transducer (Pressure Transducer) is a device or device that can sense pressure signals and convert the pressure signals into usable output electrical signals according to certain rules. A pressure sensor is a pressure measurement device with a housing, a sensor body located in the housing, a metal pressure interface and a data line interface. The housing generally adopts a cylindrical metal or plastic airtight housing. The pressure sensor can be used in the smart home field, such as a bed, etc. In the field of testing the pressure of the carrier on the bed, the pressure sensor can generally be placed under the mattress, on the bed frame, at the foot of the bed, etc. In the prior art, the structure of the pressure sensor placed on the foot of the bed is relatively common, generally a cylindrical or square casing is used to ...

AI Technical Summary

Problems solved by technology

This structure is very simple and common. After being placed on the foot of the bed, the acquisition accuracy of the pressure sensor may not be well improved due to the instability of the center or the position.
