Problems solved by technology
[0002] At present, there is no sensor that detects the weight of the vehicle and the strength of the ground soil at the same time on the car. Although there are many sensors that detect the weight, none of them have the function of detecting the strength of the ground.
However, the current earth strength instrument takes about 250s or more to complete a detection, which takes a long time

The invention relates to a pressure and ground strength combined force measuring device and belongs to the vehicle-mounted sensor technical field. The main objective of the invention is to solve the problem that a long time is taken by an automobile to detect ground strength. The pressure and ground strength combined force measuring device is characterized in that the pressure and ground strength combined force measuring device comprises an elastic body assembly, a strain gauge, a spherical shell and a ground strength sensor force measuring mechanism; the spherical shell is provided with a cylindrical cavity and a bottom groove; the elastic body assembly comprises a cylinder and silica gel plates; the center of the external surface of the cylinder is provided with an annular groove; the upper end and lower end of the cavity as well as the annular groove are filled with the silica gel plates; a supporting plate is provided with a hemispherical cavity and a countersunk head-type circular hole; the spring pin force measuring mechanism comprises a sensor, a compression spring, a guide column plate, a force measuring pin and a force measuring pin cover plate; the sensor is fixed in the bottom groove; the upper end of the compression spring sleeves the guide column plate; and the lower end of the compression spring is located in the force measuring pin. The pressure and ground strength combined force measuring device of the invention has the advantages of compact structure, small size and short detection time, and is suitable for engineering vehicles, special vehicles, military launching vehicles and the like.
Description
technical field [0001] The invention belongs to the technical field of vehicle-mounted sensors, and in particular relates to a sensor for measuring vehicle weight and ground soil strength by power generated by an electric cylinder or a hydraulic cylinder of an automobile. Background technique [0002] At present, there is no sensor that detects the weight of the vehicle and the strength of the ground soil at the same time on the car. Although there are many sensors that detect the weight, none of them has the function of detecting the strength of the ground. However, it takes about 250 seconds or more for the current earth strength meter to complete a detection, which takes a long time. Contents of the invention [0003] The object of the present invention is to provide a sensor with simple structure, small size, convenient installation, short detection time and the ability to detect vehicle weight and ground soil strength at the same time. [0004] The technical solution...
