The invention discloses a vehicle-mounted self-stabilizing weighing sensor which comprises an I-shaped elastic body, a strain gauge is arranged on the elastic body, the top surface of the elastic bodyis connected with a carriage, the bottom surface of the elastic body is connected with a connecting body, and the bottom surface of the elastic body is provided with a waist-shaped patch surface pasted with the strain gauge and a waist-shaped sealing surface used for sealing the waist-shaped patch surface; the elastic body is of a symmetrical structure, and two sides of the elastic body are provided with a U-shaped groove filled with sealant and a strain arc-shaped groove used for improving the precision of the sensor. The vehicle-mounted self-stabilizing weighing sensor has the following beneficial effects: (1) the structure is simple and compact, the manufacturing is convenient, the strength is high, and the precision is high; (2) the processing allowance of the elastic body is reduced,the processing difficulty is reduced, the structural strength damage is reduced, and the torsion resistance and overload resistance of the product are greatly improved; and (3) the measurement errorof the vehicle weighing sensor caused by horizontal tangential force generated by speed, acceleration and the like can be reduced and buffer is provided in the horizontal and vertical directions.

    本发明公开了一种车载自稳定称重传感器,包括“工”字形弹性体,弹性体上设有应变片,弹性体顶面和车厢连接,底面和连接体连接,弹性体底面设有贴有应变片的腰形贴片面和用于密封腰形贴片面的腰形密封面;弹性体为对称结构,两侧设有充有密封胶的U形槽和用于提高传感器精度的应变弧形槽。本发明具有如下有益效果:(1)结构简单紧凑、制作方便且强度高、精度高;(2)弹性体加工余量减小,加工难度降低,结构强度损伤变小,产品抗扭抗过载能力有较大提升;(3)可以减小由于速度、加速度等产生的水平切向力造成的车辆称重传感器测量误差,并且在水平和竖直方向上提供缓冲。
