The invention discloses an asymmetric lever-type pressure sensor base body for realizing consistent front-and-back pressure induction. The asymmetric lever-type pressure sensor base body comprises a sensor base body upper pressure plate (1), a sensor base body neck portion (2) and a sensor base body upper bearing plate (3) from the top down. Sensor base body lever output ends of two sensor base body levers (5) are connected through a sensor base body lever output end connection arm (6); a sensor base body upper pressure head (8) is connected with the nearest sensor base body lever output end through a sensor base body lever output end connection arm (6); and the other ends of the two sensor base body levers (5) are connected with sensor base body side walls (7) through sensor base body level bearings (12) respectively. The beneficial effects of the asymmetric lever-type pressure sensor base body are that the asymmetric lever-type pressure sensor base body produced under a rough production condition is higher in precision than a cylinder-type sensor, and the problem of different induction of induction points at different positions in front and back direction or left and right direction under the same pressure is solved.
Description
technical field [0001] The invention relates to the technical field of weighing pressure sensors for road vehicles, in particular to an asymmetrical lever type pressure sensor substrate for consistent pressure induction in front and rear directions. Background technique [0002] Today's highway management is developing more and more quickly and automatically, which requires sensors to have the ability to measure vehicle weight accurately and reliably in a fast and moving manner. (1) For road vehicle weighing scales: road vehicle weighing scales are very mature, mainly used for static weighing in factories, warehouses and other places. However, because the response speed of the weighbridge is too slow, the volume is huge, the installation is troublesome, and it can only be used for static testing, so there are still very few places where the weighbridge is used for road and its auxiliary systems, and the life of the induced strain gauge is very short. The life span is only t...
