Description

Technical Field

[0001] The present invention relates to the field of vehicles, and in particular to a functional coating automatic coating water-cutting structure, a vehicle door and a vehicle. Background Art

[0002] In existing glass (especially automobile glass), a sol-gel method is often used to form a fluorine-containing compound film on the surface of the glass. This film has a water-repellent effect. It is precisely because of the setting of this film that water droplets falling on it will form the following Figure 1 The bead shape shown in the figure makes it easy to roll down or fly away under the action of gravity and wind. When the liquid is on the solid surface, the contact angle θ between the liquid and the solid surface is used to indicate the degree of wetting of the solid surface. The larger the contact angle θ, the better the water repellency of the solid surface.

[0003] Generally speaking, glass with a contact angle θ≥90° between liquid and the glass surface is called hydrophobic glass, also known as "non-wetting glass". The life of the hydrophobic agent on the surface of this glass (closely related to the use conditions, such as climatic conditions, physical friction, chemical reactions, etc.) is 1-1.5 years. When the hydrophobic agent on the glass surface fails, it is necessary to add the hydrophobic agent to the glass surface to restore the hydrophobic function.

[0004] At present, manual coating is mostly used to add water repellent to the glass surface. The process is cumbersome, requiring the glass surface to be polished, pickled, and acid-cleaned in sequence, and then repeatedly coated with water repellent, which consumes manpower and material resources and is extremely inefficient. In addition, when adding water repellent manually, due to the limitations of manpower and environment, uneven coating of water repellent often occurs, affecting production efficiency and the quality of the water repellent layer after forming. In addition, the formed water repellent layer has the disadvantages of short life and high cost.

[0005] Regarding the related art, a hydrophobic layer is formed on the glass surface by manual coating, which is not only inefficient, but also has the problems of poor uniformity, short life and high cost of the formed hydrophobic layer. No effective solution has been given so far.

[0006] Therefore, the present invention proposes a functional coating automatic coating water-cut structure, door and vehicle to overcome the defects of the prior art. Summary of the invention

[0056] Implementation Method 1

[0057] like Figures 2 to 7As shown, the present invention provides a functional coating automatic water-cutting structure, which includes a water-cutting strip body 1 and a storage portion 2, on which a spraying assembly 6 is arranged; the storage portion 2 is a long hood-like structure extending along the length direction of the water-cutting strip body 1, and the storage portion 2 is arranged on the side of the water-cutting strip body 1 and facing away from the glass 9, and a reserved space is formed between the storage portion 2 and the water-cutting strip body 1, giving the space a double-chamber structure, that is, the reserved space between the storage portion 2 and the water-cutting strip body 1 is divided into a first storage chamber 3 and a second storage chamber 4, the first storage chamber 3 is connected to the inlet of the spraying assembly 6, and the second storage chamber 4 is used to store functional Solution (of course, without limiting the relative positions of the first storage chamber 3 and the second storage chamber 4, the second storage chamber 4 can also be connected to the inlet of the spray assembly 6, and the first storage chamber 3 is used to store the functional solution); in the embodiment where the second storage chamber 4 is used to store the functional solution, the first storage chamber 3 and the second storage chamber 4 are connected by a liquid hole 501 for one-way passage of the functional solution, so that the functional solution in the second storage chamber 4 enters the first storage chamber 3 through the liquid hole 501, and is sprayed onto the surface of the glass 9 located on one side of the water-cut strip body 1 through the outlet of the spray assembly 6, thereby realizing automatic spraying of the functional solution on the surface of the glass 9.

[0058] In the present invention, the functional solution may be, but is not limited to, a water repellent.

[0059] The structure, working principle and technical effects of the present invention are described below by taking the water repellent as an example.

[0060] In the present invention, a first storage chamber 3 and a second storage chamber 4 are formed between a water-cut strip body 1 and a storage portion 2 thereon, and a liquid passage hole 501 for one-way passage of a hydrophobic agent is provided between the first storage chamber 3 and the second storage chamber 4, wherein the hydrophobic agent is stored in the second storage chamber 4, and the first storage chamber 3 is connected to the inlet of a spray assembly 6. When the glass 9 located on one side of the water-cut strip body 1 needs to be sprayed with the hydrophobic agent, the hydrophobic agent in the second storage chamber 4 can be squeezed into the first storage chamber 3 through the liquid passage hole 501 by changing the pressure in the second storage chamber 4, and the hydrophobic agent entering the first storage chamber 3 can be further sprayed onto the surface of the glass 9 through the outlet of the spray assembly 6, thereby realizing automatic coating of the hydrophobic agent on the surface of the glass 9, and there is no need for manual wiping operation by the staff. This is simple and convenient, and the efficiency of forming a hydrophobic layer on the surface of the glass 9 is improved.

[0061] In addition, when the hydrophobic agent is sprayed on the surface of the glass 9, the glass 9 can be repeatedly raised and lowered so that the hydrophobic agent can be evenly attached to the surface of the glass 9 through the position where the water-cut strip body 1 contacts the surface of the glass 9, so as to achieve the purpose of uniform coating of the hydrophobic agent and form a uniform hydrophobic layer. This method can automatically achieve the effect of uniform coating of the hydrophobic agent, and has a high degree of automation, effectively extending the service life of the hydrophobic layer and reducing process costs.

[0062] In the present invention, the double-layer chamber design of the first storage chamber 3 and the second storage chamber 4 is such that when the hydrophobic functional solution does not need to be sprayed, the hydrophobic functional solution is only stored in the second storage chamber 4 (the first storage chamber 3 is in an empty state), and the hydrophobic functional solution will not leak from the outlet of the spraying assembly 6 during the normal lifting and lowering of the glass 9; when the hydrophobic functional solution needs to be sprayed (i.e., after the original hydrophobic layer formed on the surface of the glass 9 fails), the hydrophobic functional solution in the second storage chamber 4 is squeezed into the first storage chamber 3 by pressure and sprayed out from the outlet of the spraying assembly 6, thereby achieving the purpose of spraying the hydrophobic functional solution onto the surface of the glass 9.

[0063] In an optional embodiment of the present invention, Figures 2 to 4 As shown, a long strip partition 5 extending along the length direction of the water-cut strip body 1 is provided in the reserved space formed between the storage part 2 and the water-cut strip body 1, and the partition 5 is used to separate the reserved space between the storage part 2 and the water-cut strip body 1 to form the above-mentioned first storage cavity 3 and second storage cavity 4, and the liquid hole 501 is provided on the partition 5. The partition 5 can be integrally injection-molded with the storage part 2 or the water-cut strip body 1, and of course, the partition 5, the storage part 2 and the water-cut strip body 1 can also be integrally injection-molded.

[0064] Furthermore, there are multiple liquid holes 501, and the multiple liquid holes 501 are spaced and evenly distributed along the length direction of the water-cut strip body 1, so that when the hydrophobic agent in the second storage chamber 4 is squeezed into the first storage chamber 3 by pressure, it is ensured that the pressure in the second storage chamber 4 can be balanced, and then the hydrophobic agent in the second storage chamber 4 can evenly enter the first storage chamber 3 through the multiple liquid holes 501, and the hydrophobic agent in the second storage chamber 4 is squeezed into the first storage chamber 3 and sprayed out at one time as much as possible to achieve the best hydrophobic agent spraying effect; if the hydrophobic agent needs to be sprayed again, a certain amount of hydrophobic agent needs to be re-injected into the second storage chamber 4, and when the hydrophobic layer on the surface of the glass 9 fails again, the hydrophobic agent can be sprayed again.

[0065] In this embodiment, in order to achieve the purpose of allowing only one-way passage of the water-repellent agent through the liquid hole 501, a diaphragm-type one-way valve can be provided at the liquid hole 501. After being pressurized, the diaphragm of the diaphragm-type one-way valve can only open from the second storage chamber 4 to the first storage chamber 3, so that the water-repellent agent can enter the first storage chamber 3 from the second storage chamber 4 through the liquid hole 501 in one direction.

[0066] In the present invention, the liquid hole 501 can be formed by but is not limited to a plastic tube arranged between the first storage cavity 3 and the second storage cavity 4. The plastic tube is fixed to the partition 5 by adhesive tape. The two ends of the plastic tube are respectively connected to the first storage cavity 3 and the second storage cavity 4. The two ends of the plastic tube are the inlet and outlet of the liquid hole 501.

[0067] In an optional embodiment of the present invention, Figure 3 and Figure 4 As shown, a pressure regulating assembly 7 is provided on the storage portion 2 , and the pressure in the second storage chamber 4 can be increased by controlling the pressure regulating assembly 7 to squeeze the hydrophobic agent stored in the second storage chamber 4 into the first storage chamber 3 and sprayed out from the outlet of the spray assembly 6 .

[0068] Specifically, Figure 4 As shown, the pressure regulating assembly 7 includes an air chamber 702 arranged outside the storage portion 2, the air chamber 702 has a first end and a second end opposite to each other, the air chamber 702 is connected to the second storage cavity 4 through the first end, and a button 701 is arranged on the second end of the air chamber 702. When it is necessary to spray the water-repellent agent, the air chamber 702 can be compressed by pressing the button 701, and the gas in the air chamber 702 is squeezed from the first end of the air chamber 702 into the second storage cavity 4, thereby increasing the pressure in the second storage cavity 4 in a very short time. Under pressure, the gas in the second storage cavity 4 passes through the liquid hole 501 to allow the water-repellent agent to enter the first storage cavity 3, and is sprayed onto the surface of the glass 9 through the spraying assembly 6.

[0069] Further, such as Figure 4 As shown, a spring 703 is provided in the air chamber 702, one end of the spring 703 is connected to the button 701, and the other end of the spring 703 is connected to the inner wall of the air chamber 702. After the air chamber 702 is compressed, the air chamber 702 can be propped up again by the restoring force provided by the spring 703, so that the pressure in the second storage chamber 4 can be increased by compressing the air chamber 702 again when it is used next time.

[0070] In this embodiment, the button 701 can be made of, but not limited to, injection molding, and is fixed to the air chamber 702 by adhesive tape or PU adhesive. The button 701 is made of, but not limited to, plastic material.

[0071] In an optional embodiment of the present invention, Figure 3 and Figure 5As shown, a liquid injection hole 101 is provided on the storage part 2, and the liquid injection hole 101 is connected to the second storage chamber 4. After the water-repellent agent is sprayed once, the water-repellent agent can be injected into the second storage chamber 4 through the liquid injection hole 101, so that the water-repellent agent can be sprayed repeatedly. A sealing component 8 can be provided at the liquid injection hole 101 to prevent the water-repellent agent stored in the second storage chamber 4 from leaking out through the liquid injection hole 101.

[0072] Further, such as Figure 5 As shown, the sealing assembly 8 includes a hole cover 801 disposed on the liquid injection hole 101 , and a sealing gasket 802 is disposed between the hole cover 801 and the liquid injection hole 101 to ensure the sealing of the liquid injection hole 101 .

[0073] Specifically, Figure 5 As shown, an external thread 1011 is provided on the outer wall of the injection hole 101, and an internal thread 803 matching with the external thread 1011 is provided on the inner wall of the hole cover 801. The hole cover 801 can be screwed and covered on the injection hole 101 by matching the internal thread 803 with the external thread 1011, and when the water-repellent agent needs to be injected, the hole cover 801 can be opened by screwing it.

[0074] In this embodiment, the liquid injection hole 101 can be a round tube, which can be made of, but not limited to, injection molding, and fixed to the storage part 2 by adhesive tape or PU adhesive. The round tube is made of, but not limited to, plastic material.

[0075] In an optional embodiment of the present invention, the inlet of the spray assembly 6 and the outlet of the spray assembly 6 are connected through a spray flow channel, and the spray flow channel can be in the form of a Venturi hole. That is, the cross-sectional area of ​​the spray flow channel gradually decreases from the inlet of the spray assembly 6 to the outlet of the spray assembly 6, so that in the process of the water-repellent agent flowing out from the inlet of the spray assembly 6 to the outlet of the spray assembly 6, the pressure and atomization degree of the water-repellent agent spraying can be increased, thereby increasing the range and uniformity of the water-repellent agent spraying on the surface of the glass 9, and achieving a uniform coating effect.

[0076] Specifically, Figure 6As shown, the spray assembly 6 includes a first liquid-passing section 601, a second liquid-passing section 602 and a third liquid-passing section 603. The first liquid-passing section 601 has a first spraying flow channel, the second liquid-passing section 602 has a second spraying flow channel, and the third liquid-passing section 603 has a third spraying flow channel. The first spraying flow channel, the second spraying flow channel and the third spraying flow channel are connected in sequence, and the cross-sectional areas of the first spraying flow channel, the second spraying flow channel and the third spraying flow channel decrease. The first spraying flow channel is connected to the inlet of the spray assembly 6, and the third spraying flow channel is connected to the outlet of the spray assembly 6, so as to increase the range and uniformity of the water-repellent agent sprayed on the surface of the glass 9. Of course, the above-mentioned spray assembly 6 is not limited to a three-stage structure, and the flow channel inside it can also form a cross-sectional area decreasing form greater than three levels. The technicians may also make other changes under the inspiration of the technical essence of this application, but as long as the functions and effects achieved are the same or similar to those of this application, they should be covered within the protection scope of this application.

[0077] In an optional implementation of the present invention, Figure 3 and Figure 4 As shown, there are multiple spray assemblies 6, and the multiple spray assemblies 6 are spaced and evenly distributed along the length direction of the water-cut strip body 1 to ensure that the hydrophobic agent sprayed by the multiple spray assemblies 6 can cover the surface of the glass 9 in the length direction of the glass 9, and then the hydrophobic agent can be evenly coated on the surface of the glass 9 through the lifting operation of the glass 9 to ensure that the formed hydrophobic layer can completely cover the surface of the glass 9.

[0078] In an optional embodiment of the present invention, Figures 2 to 4 As shown, the first storage chamber 3 and the second storage chamber 4 are both long strip chambers extending along the length direction of the water-cut strip body 1. The first storage chamber 3 and the second storage chamber 4 are in an upper and lower two-layer chamber structure, and the first storage chamber 3 is located above the second storage chamber 4. Through the arrangement of this structure, the spraying assembly 6 is arranged at the upper part or the middle upper part of the water-cut strip body 1, which can not only ensure that the arrangement position of the spraying assembly 6 has a certain distance from the surface of the glass 9, so that the water repellent can be smoothly sprayed on the surface of the glass 9, but also Figure 8 As shown, since the connection between the glass 9 and the bracket 10 is located in a partial installation area, which is a non-hydrophobic agent spraying area 901, the spraying component 6 in this embodiment is arranged in a position to prevent the hydrophobic agent from being sprayed to the non-hydrophobic agent spraying area 901, and can automatically perform the hydrophobic agent spraying while ensuring that the normal assembly of the glass 9 will not be affected.

[0079] In an optional embodiment of the present invention, the water cutting strip body 1 and the storage part 2 can be integrally injection molded. Of course, in order to facilitate disassembly and assembly, the water cutting strip body 1 and the storage part 2 can also be injection molded separately, and the water cutting strip body 1 and the storage part 2 are then fixed by adhesive tape or PU adhesive.

[0080] Furthermore, the water-cut strip body 1 and the storage part 2 can be made of, but not limited to, synthetic rubber (EPDM). The consistent materials of the water-cut strip body 1 and the storage part 2 are conducive to molding, and EPDM has the characteristics of good sealing performance, high temperature resistance, and weather resistance, and has good anti-aging, impact resistance, shock resistance, and waterproof capabilities, and is more suitable for the storage of water repellent.

[0081] The process of coating the water repellent by the functional coating automatic coating water-cutting structure of the present invention is as follows:

[0082] Under normal vehicle conditions, the hydrophobic agent is stored in the second storage chamber 4 between the water-cut strip body 1 and the storage part 2; when the hydrophobic layer on the surface of the vehicle glass 9 fails, the button 701 can be manually pressed, and the hydrophobic agent in the second storage chamber 4 will enter the first storage chamber 3 through the liquid hole 501 between the second storage chamber 4 and the first storage chamber 3 under pressure, and sprayed onto the surface of the glass 9 through the spraying assembly 6 connected to the first storage chamber 3. After that, the vehicle window glass 9 is repeatedly raised and lowered so that the hydrophobic agent is evenly coated on the surface of the glass 9, and the spraying of the hydrophobic agent on the surface of the glass 9 is completed. In order to facilitate the vehicle window glass 9 to maintain a good field of vision, after the hydrophobic agent is sprayed, the excess hydrophobic agent on the surface of the glass 9 can be removed by lifting the glass 9 again, or the excess hydrophobic agent can be wiped off with a towel, and the hydrophobic process of the glass 9 can be completed.

[0083] The features and advantages of the functional coating automatic coating water-cutting structure of the present invention are:

[0084] 1. The functional coating automatic water-cut structure has a double-layer chamber structure. When the water-repellent spraying is not required, the water-repellent can be stored in the second storage chamber 4. During the normal lifting and lowering of the glass 9, the water-repellent will not leak from the outlet of the spraying component 6. When the water-repellent spraying is required (that is, after the original water-repellent layer formed on the surface of the glass 9 fails), the water-repellent in the second storage chamber 4 can be squeezed into the first storage chamber 3 by pressure and sprayed out from the outlet of the spraying component 6, so as to achieve the purpose of spraying the water-repellent onto the surface of the glass 9.

[0085] Second, the functional coating automatically applies water-cutting structure. By pressing the button 701, the spraying of the water-repellent agent can be controlled. The automatic spraying function of the water-repellent agent is started with one button, so that the water-repellent agent is evenly covered on the surface of the glass 9. In addition, since the water-repellent agent can be replenished into the second storage chamber 4 at any time as needed, the surface of the glass 9 does not need to be subjected to strict polishing, pickling and other complex treatments. Compared with the traditional water-repellent wiping process, the process of this application is less complicated, and the user can control the spraying time of the water-repellent agent by himself, which is more controllable.

[0086] Implementation Method 2

[0087] like Figure 7 and Figure 8 As shown, the present invention provides a vehicle door, which includes glass 9 and the above-mentioned functional coating automatic coating water cutting structure, the glass 9 can be arranged on the vehicle door body in a liftable manner (that is, the glass 9 can be the lifting glass of the vehicle); the functional coating automatic coating water cutting structure is arranged on the vehicle door body, and the functional coating automatic coating water cutting structure is used to spray a functional solution onto the surface of the glass 9.

[0088] The vehicle door of the present invention, after the functional solution is sprayed onto the surface of the glass 9 through the above-mentioned functional coating automatic coating water-cutting structure, can control the glass 9 to rise and fall repeatedly, so that the functional solution can be evenly coated on the surface of the glass 9, forming a stable and uniform hydrophobic layer on the surface of the glass 9.

[0089] In addition, the vehicle door of the present invention has the same characteristics and advantages as the above-mentioned functional coating automatic coating water-cutting structure, which will not be repeated here.

[0092] The vehicle of the present invention has the same characteristics and advantages as the above-mentioned functional coating automatic coating water-cutting structure, which will not be repeated here.

There is no order of precedence between the two, and they cannot be understood as indicating or implying relative importance. In addition, in the description of this application, unless otherwise specified, the meaning of "plurality" is two or more.

[0094] The above-mentioned various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.
