Description

Protection device and protection method of electronic product and electronic equipment for agricultural machinery

Technical Field

The present invention relates to the field of protection of electronic products, and in particular, to a protection device and a protection method for an electronic product, and an electronic device for an agricultural machine.

Background

The advent and popularity of agricultural machinery (e.g., tractors, harvesters, seeders) has greatly increased the efficiency of agricultural production, and in recent years, with the explosive development of science and technology, intelligent agricultural machinery has been invented and gradually applied. Unlike the conventional agricultural machinery, the intelligent agricultural machinery uses electronic products, such as Printed Circuit Board Assemblies (PCBA), in large quantities, so that the intelligent agricultural machinery gradually has the capability of autonomous operation, and it is understood that the performance and reliability of the intelligent agricultural machinery depend on the performance and reliability of the electronic products. The performance and reliability of the electronic product have close relation with the environment where the electronic product is located, namely, the performance and reliability of the electronic product have close relation with the application environment of the intelligent agricultural machinery. Experiments show that the intelligence impairment rate of the electronic products of the same type and the same quality in the field environment is twice that of the electronic products under the laboratory condition, and compared with the common field environment, the electronic products have higher failure rate in the field environment with high humidity, heat and high salt fog. With the further development of electronic products, the electronic components (such as CPUs, resistors, capacitors, and the like attached to the surface of a printed circuit board) that make up the electronic products are smaller and smaller in size, the gaps between adjacent electronic components are smaller and smaller, and the density of the electronic components is higher and higher, which results in that the performance and reliability of the electronic products are more and more easily affected by the environment.

Generally, the electronic product is locked inside a mounting box, and the mounting box is provided with one or more plugs, one end of each plug extends into the mounting box to be connected to the electronic product, and the other end of each plug extends out of the mounting box to be connected with a sensor, a driver and other mechanisms arranged on the agricultural machine after the mounting box is fixed at a corresponding position of the agricultural machine. This approach has a number of drawbacks. Firstly, when the intelligent agricultural machinery is applied to a high-humidity and high-heat application environment, water molecules with smaller sizes in the air can penetrate through gaps of the installation box and enter the installation box, so that the water molecules are easy to corrode electronic products locked in the installation box and the connecting positions of the corrosion plug and the electronic products, particularly, after the application environment reaches a certain humidity, adverse phenomena such as electrochemical migration, electric leakage and signal distortion in a high-frequency circuit of the electronic products can be caused, and meanwhile, dust in the air of the application environment is easy to adsorb ionic pollutants and settle on the surface of the electronic products and the connecting positions of the electronic products and the plug to cause faults. Secondly, when intelligent agricultural machinery was used in the application environment of high salt fog, salt fog can lead to the metal structure spare cladding of electronic product to be damaged on the one hand, and on the other hand salt fog can lead to metal conductive fracture, components and parts inefficacy with the speed of accelerated electrochemical corrosion. Thirdly, when the intelligent agricultural machinery is applied to the application environment of high damp and hot and high salt fog, the mould easily enters the inside of the mounting box and the following phenomena appear: (1) the phagocytosis and reproduction of the mold can cause the insulation of organic materials of electronic products to be reduced and damaged, and the organic acid metabolized by the mold can influence the insulation and the dielectric strength of the electronic products to generate electric arcs. In addition, the operating environment of intelligent agricultural machinery is relatively harsh, and it can produce the great vibration of intensity at the in-process of operation, and powerful great vibration can be through the electronic product of mounting box direct conduction to being locked in the inside of mounting box so that arouse the vibration of electronic product, if the electronic product is in the vibration state for a long time, especially is in the high frequency vibration state for a long time, very easily arouses to paste the electronic components who adorns at printed circuit board through surface attaching technology and drops and lead to the electronic product to damage.

(a.2) allowing the outer side 242 of the resonator 24 surrounding the electronic product 10 to be connected to the box sealer 26 and the inner side 242 of the resonator 24 to be connected to the electronic product 10, so as to maintain the electronic product 10 suspended in the protection space 21 of the protection device 20 by the resonator 24. Preferably, the outer side 242 of the damper 24 is integrally connected to the cassette enclosure 26, and the inner side 242 of the damper 24 is integrally formed with the electronic product 10.
