[0002] The controller is usually surrounded by a shell and a cover plate. The shell is made of aluminum alloy, and the cover plate is made of aluminum alloy or steel. The cover plate and the shell are sealed by using sealing rings, gaskets or sealants. Inevitably, there is a certain gap between the mating surfaces of the cover plate and the shell. In actual working conditions, salt vapor will condense and accumulate in the gap, leading to crevice corrosion. Utility Model Content

[0003] One of the purposes of the present application is to provide a housing for alleviating corrosion in the crevice.

[0004] A shell has a gap, comprising a first hydrophilic portion and a hydrophobic portion, at least part of the hydrophobic portion is arranged on the inner surface of the gap, the first hydrophilic portion is arranged on the outer surface of the gap, and the first hydrophilic portion and the hydrophobic portion are connected.

[0005] Furthermore, there are two hydrophobic parts, which are arranged up and down in the gap, and a guide channel connected to the outside is formed between the two hydrophobic parts, and the cross-sectional area of ​​the guide channel gradually decreases in the outward direction.

[0006] Furthermore, there are two hydrophobic parts, which are arranged up and down in the gap, and a guide channel communicating with the outside is formed between the two hydrophobic parts, and the cross-sectional area of ​​the guide channel does not change.

[0007] Furthermore, it also includes a sealing blocking structure, which is arranged on a side of the hydrophobic portion away from the first hydrophilic portion.

[0008] Furthermore, the sealing structure includes a sealant, and the sealant is arranged inside the gap.

[0009] Furthermore, the blocking structure further includes two second hydrophilic parts arranged up and down, and the two second hydrophilic parts are bonded together by the sealant.

[0010] Furthermore, the sealing structure is a sealing gasket or a sealing ring, and the sealing structure is interference filled in the gap.

[0011] Furthermore, both the first hydrophilic portion and the second hydrophilic portion are first remelted layers, and the thickness of the first remelted layer is 20-99 μm, so that the first remelted layer is hydrophilic.

[0012] Furthermore, the first hydrophilic portion, the hydrophobic portion and the second hydrophilic portion are membrane structures or coatings.

[0013] Furthermore, the hydrophobic portion is a second remelted layer, and the thickness of the second remelted layer is 1-19 μm, so that the second remelted layer is hydrophobic.

[0014] A vehicle controller comprises a control element, wherein the control element is arranged inside the above-mentioned housing.

[0015] The technical solution of this application has at least the following advantages:

[0016] In the present application, the hydrophobic portion has drainage properties. After water droplets gather in the gap, the hydrophobic portion will produce a drainage tendency to move the water droplets away from the hydrophobic portion. Since the first hydrophilic portion is hydrophilic, the first hydrophilic portion has a tendency to adsorb the water droplets gathered in the gap. Therefore, after the hydrophobic portion and the first hydrophilic portion are connected, at least part of the hydrophobic portion is located inside the gap, and the first hydrophilic portion is located outside the gap. The combination of the hydrophobic portion and the first hydrophilic portion has a tendency to spontaneously drain the water droplets gathered in the gap from the gap to the outside of the gap, thereby reducing the aggregation of water droplets in the gap and alleviating the degree and rate of corrosion of the material in the gap.

[0017] The bonding of the two second hydrophilic parts arranged up and down in the present application is beneficial to the curing and bonding of the sealant, improves the bonding strength, and further reduces the amount of sealant used for bonding, saving costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can also be the internal connection of two components, it can be a wireless connection, or it can be a wired connection. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0027] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0028] This embodiment provides a housing such as Figure 1-Figure 4 As shown, the housing includes a lower shell 7 and a cover plate 8, the lower shell 7 and the cover plate 8 are arranged up and down, and the matching surfaces of the lower shell 7 and the cover plate 8 enclose a gap 1.

[0029] The housing further comprises a first hydrophilic portion 2 and a hydrophobic portion 3 , wherein the first hydrophilic portion 2 is located on the outer surface of the gap 1 , and the hydrophobic portion 3 is located on the inner surface of the gap 1 .

[0030] The first hydrophilic portion 2 has hydrophilicity and can absorb water, and the hydrophobic portion 3 has water-repelling property and its surface can spontaneously drain water.

[0031] In at least one embodiment, the first hydrophilic portion 2 and the hydrophobic portion 3 are made of a hydrophilic material and a hydrophobic material, respectively, which can be a layer of film or coating, attached to the outer surface of the mounting medium, for example, a protrusion is provided, the outer side of the protrusion is provided outside the gap 1, and the remaining side is provided inside the gap 1. The first hydrophilic portion 2 is attached to the outer side of the protrusion, and the hydrophobic portion 3 is attached to the inner side of the protrusion.

[0032] In at least one embodiment, Figure 3 and Figure 4 As shown, the first hydrophilic portion 2 and the hydrophobic portion 3 are attached to the outside of the gap 1 and the inside of the gap 1 respectively, the hydrophobic portion 3 is attached to the inner surface of the gap 1, and the first hydrophilic portion 2 is attached to the surface of the lower shell 7 located outside the gap 1, the surface of the cover plate 8, or both the surface of the lower shell 7 and the surface of the cover plate 8.

[0033] Since the hydrophobic portion 3 has drainage properties and is located inside the gap 1, after water droplets gather in the gap 1, the hydrophobic portion 3 will have a drainage tendency to move the water droplets away from the hydrophobic portion 3. Since the first hydrophilic portion 2 has hydrophilic properties and is arranged outside the gap 1, the first hydrophilic portion 2 has a tendency to adsorb the water droplets gathered in the gap 1. Therefore, after the hydrophobic portion 3 and the first hydrophilic portion 2 are connected, the combination of the hydrophobic portion 3 and the first hydrophilic portion 2 has a tendency to discharge the water droplets gathered in the gap 1 from the hydrophobic portion 3 into the first hydrophilic portion 2, thereby realizing the function of spontaneously discharging the water droplets from the gap 1, reducing the aggregation of water droplets in the gap 1, and alleviating the corrosion degree and corrosion rate of the material in the gap 1.

[0034] It can be understood that the above technical purpose can also be achieved when the hydrophobic portion 3 is located outside the gap 1.

[0035] There are two hydrophobic parts 3, which are arranged in an upper and lower space in the gap 1. A guide channel 6 is formed between the two hydrophobic parts 3. The guide channel 6 plays a role in guiding flow. The combination of the hydrophobic part 3 and the first hydrophilic part 2 guides the gathered water droplets out of the gap 1 along the guide channel 6.

[0036] In at least one embodiment, the structure of the flow guide channel 6 is as follows: Figure 2 or Figure 4As shown, the cross-sectional area of ​​the guide channel 6 gradually decreases in the outward direction. The guide channel 6 is wide inside and narrow outside. The water is driven by the contact angle. Under the restriction of the above structure, the contact angle of the guide channel 6 from the inside to the outside gradually increases. The more inward, the greater the energy generated. The energy spontaneously flows from the large place to the low place, and then the guide channel 6 itself has a movement tendency to discharge water droplets outward. Therefore, the guide channel 6 with a wide inside and narrow outside shape further improves the drainage effect.

[0037] In at least one embodiment, the structure of the flow guide channel 6 is as follows: Figure 1 or Figure 3 As shown, the cross-sectional area of ​​the guide channel 6 remains unchanged in the outward direction, which is beneficial to the manufacture of the guide channel 6 and reduces the manufacturing cost.

[0038] like Figure 1 and Figure 2 As shown, the housing further comprises a sealing structure, which is arranged on a side of the hydrophobic portion 3 away from the first hydrophilic portion 2 .

[0039] In at least one embodiment, the sealing structure is a sealing gasket or a sealing ring, and the sealing structure is interference filled in the gap 1. For example, when the gap 1 is annular, a sealing ring is used as the sealing structure. When the gap 1 is in other shapes, a sealing gasket can be used as the sealing structure.

[0040] In at least one embodiment, the sealing structure includes a sealant 5, which is arranged inside the gap 1 and adheres to the upper and lower boundaries of the gap 1 to achieve a sealing effect.

[0041] In at least one embodiment, the blocking structure further includes two second hydrophilic parts 4 arranged up and down, and the two second hydrophilic parts 4 can be respectively attached to the upper and lower boundaries of the gap 1, and then the two second hydrophilic parts 4 are bonded by a sealant 5. The second hydrophilic part 4 can be made of a hydrophilic material and has a tendency to absorb water droplets.

[0042] The two second hydrophilic parts 4 are bonded by the sealant 5. The addition of hydroxyl groups will improve the bonding effect. Therefore, since the second hydrophilic part 4 has a tendency to absorb water droplets, the second hydrophilic part 4 is conducive to the curing and bonding of the sealant, thereby improving the bonding strength. The second hydrophilic part 4 can also be a coating or a membrane structure.

[0043] In at least one embodiment, the first hydrophilic portion 2 and the second hydrophilic portion 4 are both the first remelted layer, and the hydrophobic portion 3 is the second remelted layer. In this embodiment, a microstructure is formed by adjusting the laser power or cleaning, including the first remelted layer and the second remelted layer, thereby making the surface denser.

[0044] By adjusting the sizes of the first remelting layer and the second remelting layer, the first remelting layer is made hydrophilic and the second remelting layer is made hydrophobic. Taking the first hydrophilic portion 2 as an example, the outer surface of the gap corresponding to the first hydrophilic portion 2 is processed into a remelting state through a laser cleaning process to form a first remelting layer, and the thickness of the first remelting layer is 20-99 μm, so that the first remelting layer is hydrophilic.

[0045] The thickness of the second remelted layer is set to 1-19 μm, so that the second remelted layer has hydrophobicity.

[0046] In at least one embodiment, the hydrophobic portion 3 is a hydrophobic surface, and the first hydrophilic portion 2 and the second hydrophilic portion 4 are hydrophilic surfaces. The hydrophobic surface and the hydrophilic surface can be constructed by plasma cleaning, micromachining, etching, anodizing or spraying. For example, when the hydrophobic portion 3 is a membrane structure, the microstructure of the membrane structure surface can be constructed by plasma cleaning, micromachining, etching, anodizing or spraying to make it hydrophobic; or when the hydrophobic portion 3 is a coating, the surface properties of the inner surface of the gap 1 can be changed by spraying, and the microstructure of the inner surface of the gap 1 can be changed to make it hydrophobic. Similarly, the materials of the shell 7 and the cover plate 8 mentioned in this embodiment are not limited to aluminum alloy or steel.

[0047] This embodiment also provides a vehicle controller, including a control element, which is arranged inside the above-mentioned housing.

[0048] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection created by this application.
