Description

Technical Field

[0001] This utility model relates to the field of motor cover technology, specifically to a motor cover with a cross-shaped mesh sealing structure. Background Technology

[0002] The mating surface between the motor cover and the housing is crucial for ensuring an internal seal and preventing lubricant leakage and the intrusion of external dust and moisture. Currently, most motor cover designs feature a smooth, flat sealing surface. A liquid sealant (such as silicone sealant or anaerobic adhesive) is applied to this smooth surface to achieve a seal.

[0003] However, this traditional smooth sealing surface has many inherent defects in practical applications and production:

[0004] (1) Poor positioning of sealant: Liquid sealant is prone to uncontrolled flow on smooth surfaces, resulting in uneven coating path width, with some areas being too thick or too thin. Areas that are too thin are prone to forming leakage channels, while areas that are too thick are prone to "extrusion" during tightening, which also affects the sealing effect.

[0005] (2) Adhesion depends on pure chemical bonding: The bond between the sealant and the smooth surface mainly depends on intermolecular forces (van der Waals forces) and chemical bonding forces. This bonding method has extremely high requirements for surface cleanliness and activation energy. Any trace of contamination or weak boundary layer will lead to a significant decrease in adhesion, and interface peeling is prone to occur under stress such as vibration and thermal cycling.

[0006] (3) The process stability is difficult to control: slight fluctuations in the coating process (such as dispensing pressure and moving speed) will be amplified on a smooth surface, directly leading to inconsistencies in the morphology of the sealant and poor product quality consistency.

[0007] Therefore, there is an urgent need for a new structure for motor cover sealing surfaces that can improve coating performance and enhance adhesion through structural design. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model proposes a motor cover plate with a cross-shaped mesh sealing structure. By setting a cross-shaped mesh pattern in the blank area between the sealing mounting plate and the end edge of the cover plate body, the coating performance of the sealant on the motor cover plate can be effectively improved, the adhesion of the sealant can be enhanced, and thus the sealing performance of the motor cover plate can be improved.

[0009] To achieve the above technical solution, this utility model provides a motor cover plate with a cross-shaped mesh sealing structure, comprising: a cover plate body, a sealing mounting plate integrally provided in the central area of ​​the bottom surface of the cover plate body, a cross-shaped mesh pattern provided in the blank area of ​​the sealing mounting plate and the end edge of the cover plate body, two blank dots provided on the sealing mounting plate, and a cross-shaped mesh pattern also provided on the blank dots, the cross-shaped mesh pattern being composed of multiple intersecting ribs, the height of the ribs being 0.1mm to 0.5mm, the width being 0.2mm to 0.8mm, and the spacing between adjacent ribs being 1mm to 3mm.

[0010] In the above scheme, during actual operation, when the mating surface between the motor cover and the housing needs to be sealed, sealant only needs to be applied to the cross-shaped mesh pattern set in the blank area of ​​the sealing mounting plate and the cover body, as well as the cross-shaped mesh pattern set on the blank dots. The cross-shaped mesh pattern can effectively block and restrict the random flow of liquid sealant, guiding it to distribute along the preset groove path, thereby ensuring the consistency of the coating width and the accuracy of the position. After the sealant flows into and cures in the grooves of the cross-shaped mesh pattern, it forms an "anchoring" structure, which greatly enhances the interface adhesion and peel resistance. Moreover, compared with a smooth plane, the mesh structure significantly increases the actual contact area between the sealant and the metal, providing a physical basis for further improving the bonding strength, thereby effectively improving the sealing performance of the mating surface between the motor cover and the housing. Furthermore, the height, width, and spacing of the ribs forming the cross-shaped mesh pattern should not be too large or too small. When the height, width, and spacing of the ribs are too large, the adhesion and dispersion capabilities of the cross-shaped mesh pattern for the sealant are significantly reduced, failing to enhance the adhesion of the sealant interface. When the height, width, and spacing of the ribs are too small, it increases the difficulty of processing the cross-shaped mesh pattern and also increases the amount of sealant applied, increasing processing costs and sealant usage costs. Experiments have shown that when the height of the ribs is 0.1mm to 0.5mm, the width is 0.2mm to 0.8mm, and the spacing between adjacent ribs is 1mm to 3mm, a good sealing effect can be achieved at the mating surface between the motor cover and the housing.

[0011] Preferably, the cross-shaped mesh pattern is composed of multiple intersecting ribs forming microgrooves, the depth of which is 0.1–0.5 mm and the width of which is 1–3 mm. The depth and width of the microgrooves have a significant impact on the adhesion and dispersion capabilities of the sealant. Experiments have shown that when the groove depth is 0.1–0.5 mm and the width is 1–3 mm, it effectively improves both the adhesion and dispersion capabilities of the sealant.

[0012] Preferably, the included angle α between two intersecting ribs is 90 degrees.

[0013] Preferably, both the cover plate body and the sealing mounting plate are made of aluminum alloy.

[0014] Preferably, the cross-shaped mesh pattern is integrally processed by an embossing process.

[0015] The beneficial effects of the motor cover plate with a cross-shaped mesh sealing structure provided by this utility model are as follows: The motor cover plate with a cross-shaped mesh sealing structure has a simple structure, ingenious design, and is easy to process. By setting a cross-shaped mesh pattern in the blank area of ​​the sealing mounting plate and the end edge of the cover plate body, the coating performance of the sealant on the motor cover plate can be effectively improved, the adhesion of the sealant can be enhanced, and thus the sealing performance of the motor cover plate can be improved.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: A motor cover with a cross-shaped mesh sealing structure.

[0021] Reference Figures 1 to 2As shown, a motor cover with a cross-shaped mesh sealing structure includes: a cover body 1, a sealing mounting plate 2 integrally formed in the central area of ​​the bottom surface of the cover body 1, both the cover body 1 and the sealing mounting plate 2 being made of aluminum alloy, and a cross-shaped mesh pattern 3 being formed in the blank area at the end edge of the sealing mounting plate 2 and the cover body 1, and two blank dots on the sealing mounting plate 2, each blank dot also having a cross-shaped mesh pattern 3, the cross-shaped mesh pattern 3 being integrally formed by an embossing process. The cross-shaped mesh pattern 3 is composed of multiple intersecting ribs 31, each rib 31 having a height of 0.2 mm, a width of 0.4 mm, a spacing of 2 mm between adjacent ribs 31, and an included angle α of 90 degrees between two intersecting ribs 31. The cross-shaped mesh pattern 3 contains micro-grooves 32 formed by multiple intersecting ribs 31, each groove 32 having a depth of 0.2 mm and a width of 2 mm. The depth and width of microgrooves have a significant impact on the adhesion and dispersion of sealants. Experiments have shown that when the groove depth is 0.2 mm and the width is 2 mm, it has a good effect on improving the adhesion and dispersion of sealants.

[0022] In this example, during actual operation, when it is necessary to seal the mating surface between the motor cover and the housing, sealant only needs to be applied to the cross-shaped mesh pattern 3 set in the blank area of ​​the sealing mounting plate 2 and the cover body 1, as well as the cross-shaped mesh pattern 3 set on the blank dots. The cross-shaped mesh pattern 3 can effectively block and restrict the random flow of liquid sealant, guiding it to distribute along the preset groove 32 path, thereby ensuring the consistency of the coating width and the accuracy of the position. After the sealant flows into and cures in the groove of the cross-shaped mesh pattern 3, it forms an "anchoring" structure, which greatly enhances the interface adhesion and anti-peeling ability. Moreover, compared with a smooth plane, the cross-shaped mesh pattern 3 structure significantly increases the actual contact area between the sealant and the metal, providing a physical basis for further improving the bonding strength, thereby effectively improving the sealing performance of the mating surface between the motor cover and the housing. Furthermore, the height, width, and spacing of the ribs 31 constituting the cross-shaped mesh pattern 3 should not be too large or too small. When the height, width, and spacing of the ribs 31 are too large, the adhesion and dispersion capabilities of the cross-shaped mesh pattern 3 to the sealant are significantly reduced, failing to achieve the effect of enhancing the adhesion of the sealant interface. When the height, width, and spacing of the ribs 31 are too small, it will increase the processing difficulty of the cross-shaped mesh pattern 3 and increase the amount of sealant applied, thus increasing processing costs and sealant usage costs. Experiments have shown that when the height of the ribs is 0.2 mm, the width is 0.4 mm, and the spacing between adjacent ribs is 2 mm, the optimal sealing effect can be achieved at the joint surface between the motor cover and the housing.

[0023] This motor cover with a cross-shaped mesh sealing structure is simple in structure, ingenious in design, and easy to process. By setting a cross-shaped mesh pattern in the blank area between the sealing mounting plate and the end edge of the cover body, the coating performance of the sealant on the motor cover can be effectively improved, the adhesion of the sealant can be enhanced, and thus the sealing performance of the motor cover can be improved.

[0026] Example 3: A motor cover with a cross-shaped mesh sealing structure.

[0027] In this embodiment, the height of the rib is 0.5 mm, the width is 0.8 mm, the spacing between adjacent ribs is 3 mm, the depth of the groove is 0.5 mm, the width is 3 mm, and the remaining technical features are the same as in Embodiment 1.
