Copper connecting column 1 has excellent conductivity, can effectively reduce the loss in the process of current transmission;Aluminum alloy connecting column 1 has the advantages of light weight and corrosion resistance, reduces the overall weight while ensuring the stability of connection. The external fixation of connecting column 1 has end cover body 2, and the connection mode of end cover body 2 is mostly welding, screw connection or tight fit and other firm processes. The external of end cover body 2 is provided with heat dissipation hole 3, and the number of heat dissipation hole 3 is generally several to tens of different, is evenly distributed on the surface of end cover body 2, so as to ensure that heat can be evenly dissipated. The diameter or side length of heat dissipation hole 3 is determined according to the heat dissipation demand, and is generally between several millimeters to several centimeters. Around heat dissipation hole 3, some special treatments are carried out, such as rounding or increasing reinforcing ribs, rounding can reduce stress concentration, prevent cracks in high-temperature or vibration environment;

[0030] The outer part of the end cover body 2 is fixedly connected with a sealing mechanism, which can effectively prevent foreign matter from entering the inside of the motor controller, ensuring the cleanliness and safety of the internal electrical components. The inside of the end cover body 2 is provided with a protection mechanism, which can enhance the high-temperature resistance, corrosion resistance and tear resistance of the end cover body 2, prolong the service life of the end cover, and ensure the safe operation of the motor controller. The protection mechanism includes a high-temperature resistant layer 10, which serves as the first line of defense against high-temperature environments. The material of the high-temperature resistant layer 10 is usually ceramic material or high-temperature alloy with excellent high-temperature resistance. Ceramic materials such as alumina ceramic and silicon nitride ceramic have extremely high melting points and good heat insulation properties, which can effectively block the transfer of high-temperature heat to the inside of the end cover body 2, protecting the internal electrical components from high temperatures. The bottom of the high-temperature resistant layer 10 is fixedly connected with a corrosion-resistant layer 11, which can effectively prevent the motor controller from being corroded in humid, acidic or alkaline environments, ensuring the structural integrity and electrical performance of the end cover body 2. The material of the corrosion-resistant layer 11 is usually corrosion-resistant paint or metal plating. Corrosion-resistant paints such as epoxy resin paint and polyurethane paint have good corrosion resistance and adhesion, which can form a continuous protective film on the inner surface of the end cover body 2, preventing the contact of corrosive media with the end cover body 2;

[0031] The outer part of the corrosion-resistant layer 11 is fixedly connected with a tear-resistant layer 12, which can improve the mechanical strength and tear resistance of the end cover body 2, preventing the end cover body 2 from being torn or damaged by external forces during installation, use or transportation. The material of the tear-resistant layer 12 is usually high-strength fiber material or metal sheet. High-strength fiber materials such as carbon fiber and aramid fiber have extremely high strength and modulus, which can effectively enhance the tear resistance of the end cover body 2. The outer part of the high-temperature resistant layer 10 is arranged inside the end cover body 2, and the outer part of the end cover body 2 is connected with a sealing plate 9. The sealing plate 9 works cooperatively with the sealing mechanism of the end cover body 2 to form a sealing system for the end cover, effectively preventing foreign matter from entering and ensuring the normal operation and service life of the motor controller;

[0032] The sealing mechanism includes a telescopic rod 6 composed of an inner rod and an outer rod. The inner rod can slide freely inside the outer rod, and the cooperation between the two is precise. After fine processing and treatment, the sliding process is smooth and unobstructed, effectively reducing friction resistance and avoiding jamming. The surfaces of the inner rod and the outer rod are treated with anti-rust, such as electroplating or spraying anti-rust paint, to enhance their durability in humid or harsh environments and prevent rust from affecting their normal use and sealing performance. The outer part of the telescopic rod 6 is provided with a spring assembly, which provides the sealing plate 9 with the necessary elastic force for automatic sealing;

[0033] The elastic assembly comprises a spring 7, the surface of which is treated specially, such as phosphating or galvanizing, to improve its corrosion resistance and prolong its service life. One end of the spring 7 is fixedly connected to the outside of the end cover body 2, and the connection mode can adopt welding, hook connection or a specially designed connecting seat. The welding ensures firmness without virtual welding; the outside of the spring 7 is fixedly connected to the outside of the end cover body 2, and when the sealing plate 9 is moved under the action of external force, the spring 7 is correspondingly stretched and contracted to generate elastic force, so that the sealing plate 9 always maintains close contact with other components to realize the automatic sealing function. The outside of the telescopic rod 6 is fixedly connected with the sealing plate 9, the shape and size of the sealing plate 9 are designed according to the external contour of the end cover body 2 and the sealing requirement, and the sealing plate 9 is usually rectangular, circular or annular, the surface of which is smooth and has a certain elastic deformation capacity, which can be tightly attached to the matching components under the elastic force of the spring 7 to effectively prevent impurities such as dust and moisture from entering. The outside of the telescopic rod 6 is fixedly connected to the outside of the end cover body 2;

[0034] Reference Figures 3 to 4 The outer part of the corrosion-resistant layer 11 is arranged inside the end cover body 2, and the corrosion-resistant layer 11 is a key structure for protecting the end cover body 2 from corrosion, and the corrosion-resistant paint or metal plating layer adopted by the corrosion-resistant layer 11 is uniformly and densely attached to the inner wall of the end cover body 2. If it is a corrosion-resistant paint, such as an epoxy resin paint, it forms a continuous gap-free protective film on the inner surface of the end cover body 2 due to its good chemical stability and corrosion resistance. The outer part of the tear-resistant layer 12 is arranged inside the end cover body 2, and the high-strength fiber material or metal sheet selected for the tear-resistant layer 12 is tightly attached to the corrosion-resistant layer 11. Taking carbon fiber as an example, it has ultra-high strength and modulus, and the fiber filaments interweave to form a high-strength network structure. During the manufacturing process, the carbon fiber filaments are first subjected to special impregnation treatment to make them impregnated in the resin matrix, and then laid on the surface of the corrosion-resistant layer 11 according to the design requirements, and then cured through heat pressing or curing process to firmly bond the carbon fiber and the corrosion-resistant layer 11 together to form an integral tear-resistant structure. The bottom of the tear-resistant layer 12 is fixedly connected with the reinforcing layer 13, and the reinforcing layer 13 further improves the overall strength and stability of the end cover body 2;

[0035] The reinforcing layer 13 can adopt a metal grid structure or a high-strength composite material. The metal grid structure, such as an aluminum alloy grid, is woven from aluminum alloy wires, and the grid shape and size are designed according to the stress conditions and structural characteristics of the end cover body 2. The outer part of the reinforcing layer 13 is arranged on the outside of the end cover body 2. The outside of the connecting column 1 is fixedly connected with a plurality of connecting plates 4, which are transition components connecting the connecting column 1 and the connecting ring 5. The material of the connecting plate 4 is generally matched with that of the connecting column 1, and is usually a metal material, such as aluminum alloy or stainless steel. The shape of the connecting plate 4 is generally designed as a rectangle or a trapezoid, and the thickness is determined according to the connection strength requirement, which is generally between a few millimeters and tens of millimeters. The outer part of the connecting plate 4 is fixedly connected with the connecting ring 5, which is mainly used to enhance the connection integrity and stability between the connecting column 1 and other components. The material of the connecting ring 5 is generally metal, such as copper or stainless steel, and the shape is ring-shaped. The inner diameter and outer diameter of the ring are determined according to the connection requirements and structural layout. The inner diameter is generally slightly larger than the outer diameter of the connecting column 1 to facilitate installation, and the outer diameter is determined according to the connection requirements with other components.

[0036] Working principle: First, relying on its multi-layer protection structure to ensure the safe operation of the motor controller in high temperature and harsh environment. The connecting column 1, as the key structure connecting the end cover and other components of the motor controller, adopts a metal material with strong electrical conductivity and high mechanical strength to ensure stable current transmission and reduce overall weight. The end cover body 2 is fixed with the connecting column 1 by welding or screw connection, and the surface is provided with a plurality of uniformly distributed heat dissipation holes 3 to effectively dissipate heat and prevent overheating.

[0037] The sealing mechanism transmits pressure to the telescopic rod 6 by pressing the end cover body 2, which in turn enables the telescopic rod 6 to be squeezed by the spring 7, so that the sealing plate 9 can be clamped on the outside of the motor controller to prevent foreign matter from entering the inside of the motor controller and ensure the cleanliness of the internal electrical elements. The internal protection mechanism enhances the high temperature resistance, corrosion resistance and tear resistance of the end cover, prolonging the service life. The high temperature resistant layer 10 adopts ceramic material or high temperature alloy to effectively block high temperature heat and protect internal components. The corrosion resistant layer 11 uses corrosion resistant paint or metal plating to form a continuous protective film to resist the invasion of moisture and corrosive media. The tear resistant layer 12 enhances the mechanical strength by using high strength fiber material or metal sheet to prevent tearing during use.

[0038] The telescopic rod 6 and the spring assembly work together to provide the elastic force required for the automatic sealing of the sealing plate 9, ensuring the sealing performance. The spring 7 is treated with anti-rust and is stably connected, which can keep the sealing plate 9 in close contact with other components under external force, effectively preventing dust and moisture from entering. The reinforcing layer 13 further improves the overall strength and stability of the end cover, ensuring reliability in high temperature and vibration environment. Through the synergistic effect of these structures, the entire device ensures the safety and long service life of the motor controller under extreme conditions.
