Magnetic field detection sensor, magnetic field detection device and use method

Abstract

The invention discloses a magnetic field detection sensor, a magnetic field detection device and a use method, and the sensor comprises a vehicle body chassis, a shock absorber disposed at the lower end of the vehicle body chassis, a protective cover box disposed at the bottom end of the vehicle body chassis and at one side of the shock absorber, an equidistant Hall sensor group disposed in the protective cover box, and a vertical rod disposed in the protective cover box. A sliding block is arranged on the side wall of the equidistant Hall sensor group and slidably arranged on a vertical rod in a sleeving mode, a fixed-distance locking assembly is arranged between the vertical rod and the sliding block, a supporting frame is arranged on the side wall of a damper moving part, a fixing frame is arranged on the side wall of the supporting frame, a magnetic element is arranged at the top end of the fixing frame, and a protective cover is arranged outside the fixing frame and the magnetic element in a sleeving mode. The installation height of the equidistant Hall sensor group can be adjusted through sliding of the sliding block on the vertical rod, the locking state of the spring sleeve rod is adjusted through the step screw hole, and a main corrugated protection cover and an auxiliary corrugated protection cover carry out waterproof and dustproof protection on a laser range finder and a magnetic element respectively.

Description

technical field [0001] The invention belongs to the technical field of vehicle load detection, and in particular relates to a magnetic field detection sensor, a magnetic field detection device and a use method. Background technique [0002] Car refers to a car used to carry people and their belongings, and the seats are arranged between the two axles, including the driver, the maximum number of seats is not more than nine. [0003] For the safety of drivers and passengers, cars are prohibited from being overloaded. However, in the prior art, cars often do not detect the load of the vehicle, causing the driver to be negligent. Therefore, there is a car load measurement system in the prior art. The structure is composed of magnetic elements and Hall sensors. When the system weighs, it will cause the magnetic elements to approach the Hall sensor. During this period, the distance change will cause the Hall electromotive force to change. The Hall sensor outputs a corresponding vo...
