Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] Embodiment: please refer to Figures 1 to 3The utility model discloses an installation structure of inductive sensor provides a technical scheme: an installation structure of inductive sensor, including inductive sensor 3, still including two symmetrical settings and the installation support 4 of bow-shaped structure of arch. The first end recess between two installation supports 4 is used for clamping the frame 1;The middle recess of two installation supports 4 is all set up with first screw hole, and the first long bolt 5 is arranged between two first screw holes, and the first long bolt 5 is threadedly connected with the first lock nut 6, and the first long bolt 5 cooperates the first lock nut 6 and can connect two installation supports 4 closely together;The second end recess between two installation supports 4 clamps and fixes the installation backboard 7, and inductive sensor 3 is fixedly connected on the installation backboard 7 and towards spring steel plate 2.

[0023] On the basis of the above embodiment, the width of the middle recess of the installation support 4 gradually decreases from the first end to the second end of the installation support 4, that is, the end of the installation support 4 close to the installation backplate 7 is provided with a small head to facilitate the installation backplate 7 to further connect and fix the inductive sensor 3. Specifically, the two ends of the installation backplate 7 extend outward beyond the second end of the installation support 4 and are each provided with two second screw holes, the inductive sensor 3 is provided with a third screw hole corresponding to the second screw hole, a second long bolt 8 is arranged between the second screw hole and the third screw hole, a second lock nut 10 is threadedly connected to the second long bolt 8, and the inductive sensor 3 is firmly fixed on the installation backplate 7 by the cooperation of the four second long bolts 8 and the second lock nuts 10. A pressure pad nut 9 is also threadedly connected to the second long bolt 8, and the pressure pad nut 9 is located between the inductive sensor 3 and the installation backplate 7. By providing the pressure pad nut 9, the installation backplate 7 can be prevented from deforming when the second lock nut 10 is tightened too tightly.

[0024] The inductive sensor 3 of the present embodiment detects the relative distance between the vehicle frame 1 and the suspension spring steel plate 2 / axle fixing member. The inductive sensor 3 uses the eddy current phenomenon to detect the distance of a metal object. The sensor probe has a small coil, which is driven by a controller to generate an excitation source (high frequency, tens of kilohertz to tens of megahertz) to generate an oscillating electromagnetic field. When approaching the measured object, an induced current is generated on the surface of the measured object, and an opposite electromagnetic field is generated. The distance between the measured object and the inductive sensor 3 is determined according to the strength of the opposite electromagnetic field.

[0025] The present embodiment discards the previous welding installation method of various load sensors, and uses a clamping method for installation without welding and without the need for a connecting member between the sensor and the detected surface / object. The vehicle frame 1 is an I-beam structure, and the sensor is installed and fixed on the frame 1 by using the extension structure on the lower side of the I-beam structure.

[0026] The specific installation mode is as follows: the first end of the two arch-shaped installation supports 4 is clamped below the vehicle frame 1, the second end of the installation support 4 is clamped to the installation back plate 7, the first long bolt 5 is used to pass through the first screw hole and then locked by the first locking nut 6, the inductive sensor 3 is connected to the installation back plate 7 by four second long bolts 8 in sequence through the third screw hole and the second screw hole, and the second locking nut 10 is used to fix on the other side of the installation back plate 7.

[0027] Before the vehicle is loaded, the distance between the spring steel plate 2 and the vehicle frame 1 is detected and recorded by the inductive sensor 3, when the vehicle is loaded, the spring steel plate 2 starts to deform due to the change of the weight of the goods, the distance between the spring steel plate 2 and the vehicle frame 1 is reduced, the inductive sensor 3 detects the distance value between the spring steel plate 2 and the vehicle frame 1 in real time and uploads to the sensor host, when the loading is finished, the distance value between the spring steel plate 2 and the vehicle frame 1 reaches the minimum value of the current loading, the recorded distance of the inductive sensor 3 before loading is subtracted from the recorded distance of the inductive sensor 3 after loading to obtain the change value of the distance of the inductive sensor 3, the vehicle frame 1 is installed with multiple inductive sensors 3 to obtain the distance change values of the multiple inductive sensors 3, the host uploads the multiple distance change values to the server, and the server estimates the loading weight of the vehicle by filtering the distance data through various algorithms.

[0028] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, the range of the utility model is defined by the appended claims and its equivalents.
