Problems solved by technology
[0003] However, when the vehicle is driving, it is inevitable that the road surface will be uneven, and the frame will shake from side to side or downward, which will affect the service life of the load cell and the accuracy of measurement.
Especially when the vehicle is loaded with a heavy weight, the distance between the frame and the axle will be compressed sharply, which may cause damage to the load cell and make it unusable

The invention discloses a vehicle load sensor, which comprises a lower casing, which is arranged vertically and whose bottom is fixedly connected to the axle; Displacement sensor, which includes a sleeve, a first capacitor plate, a vertical bar, a second capacitor plate, the bottom of the vertical bar is provided with a first spring; a plurality of buffer units, which are arranged at intervals between the sleeve tube and the second capacitor plate along the circumferential direction Between the upper shells; a support unit, which is arranged in the lower shell, includes: a support block, the top surface of which is provided with a hemispherical first groove, and a plurality of arc-shaped slides are arranged on the first groove Slot; a plurality of support rods, one arc-shaped chute corresponds to a support rod, one end of any support rod is hinged to the bottom of the vertical rod, and the other end is hinged to a pulley, and any pulley is slidingly clamped on the corresponding arc inside the chute. The invention improves the anti-seismic performance, has the beneficial effects of prolonging the service life and ensuring the measurement accuracy.
Description
technical field [0001] The invention relates to the technical field of sensors. More specifically, the present invention relates to a vehicle load sensor. Background technique [0002] In order to ensure road traffic safety, there are strict regulations on the loading weight of vehicles. Overloading will not only affect the service life of vehicles and roads, but will even cause traffic accidents, which will cause major losses to life and property safety. With the development of sensing technology, more and more vehicle load sensors are entering the market. At present, the load sensor is mostly a displacement sensor that measures the distance between the frame and the axle. The two ends of the load sensor are respectively connected to the frame and the axle, and the signal of the loading weight is obtained by measuring the change in the distance between the frame and the axle. . [0003] However, when the vehicle is running, it is inevitable that the road surface will be ...
