Description

Technical Field

[0001] This invention relates to the field of windshield wiper technology, and in particular to a windshield wiper structure, windshield wiper system, and vehicle. Background Technology

[0002] In the existing technology, vehicles are equipped with windshields. To remove dust or rainwater and other foreign objects accumulated on the windshield, wipers are generally used to wipe it. The wipers are equipped with plasma generators, and the plasma generated by the plasma generators acts directly on the windshield to wipe it. However, there is a problem with the small range of action, which can easily leave water film or frost on the windshield, causing wear and tear on the wipers. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of this invention is to provide a windshield wiper structure that allows plasma wind, formed by the ionization of air within the air duct, to be blown toward the windshield, thereby dispersing the OH groups in the plasma. - Active ions such as O3 break the hydrogen bonds of water molecules, which can reduce surface tension and decompose the oil film into volatile small molecules. At the same time, the plasma wind blows the discrete water droplets and oxide particles away from the windshield.

[0004] The present invention further proposes a windshield wiper system.

[0007] Therefore, this wiper structure allows the plasma wind generated by the ionization of air within the duct to be blown toward the windshield. In this way, the OH radicals in the plasma... - Active ions such as O3 break the hydrogen bonds of water molecules, reducing surface tension and decomposing the oil film into volatile small molecules. Simultaneously, the plasma wind blows away discrete water droplets and oxide particles from the windshield. Furthermore, before the wiper blades reach the water film, the water film has already been dispersed, thinned, or evaporated by the plasma wind, thus reducing wear on the wiper blades to some extent. Additionally, the plasma wind itself is cold plasma, requiring no additional heating, and can be effectively absorbed by the active ions (OH-). - O3 breaks the molecular bonds on the surface of ice crystals, producing a local "micro-sublimation" effect, which can significantly reduce the adhesion of ice and frost.

[0025] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0026] The following is for reference. Figures 1-22 A wiper structure 100 according to an embodiment of the present invention is described.

[0027] like Figures 1-4 As shown, according to a first aspect embodiment of the present invention, the wiper structure 100 includes: a wiper frame 1 and a plasma generating device 2. The wiper frame 1 has an air duct 11, the air duct 11 having an air inlet 111 and an air outlet 112. The plasma generating device 2 is disposed in the air duct 11, thereby generating plasma wind in the air duct 11.

[0028] The wiper structure 100 mainly consists of a wiper frame 1 and a plasma generator 2. The plasma generator 2 can use high voltage to ionize air to form plasma. Driven by a high voltage electric field, the plasma can move directionally and collide with the air to generate macroscopic ion wind. Since the wiper frame 1 forms an air duct 11, the plasma generator 2 can ionize the air within the air duct 11. In this way, plasma wind can be generated within the air duct 11 and blown towards the windshield of the vehicle.

[0029] Specifically, the wiper structure 100 generates an ion wind of 1-4 m / s by ionizing air with a high voltage of 15-25 kV at the leading edge of the blade, and the OH in the plasma... - Active ions such as O3 break the hydrogen bonds of water molecules, which can reduce surface tension and decompose the oil film into volatile small molecules. At the same time, the plasma wind blows the discrete water droplets and oxide particles away from the windshield. The rubber blade can remove the residual liquid film with just a light press. The residual water droplets are less than 5%, which can realize a three-level cleaning mechanism of "active chemical decomposition, electro-fluid drive and mechanical sweeping".

[0030] Furthermore, before the wiper blade of the wiper structure 100 reaches the water film, the water film has already been dispersed, thinned, or evaporated by the plasma wind, thus reducing wear on the wiper blade of the wiper structure 100 to a certain extent. Additionally, the plasma wind can effectively decompose oil film and inhibit frost, reducing washer fluid consumption. Moreover, the plasma wind itself is cold plasma, requiring no additional heating, and can pass through the active ions OH... - O3 breaks the molecular bonds on the surface of ice crystals, producing a local "micro-sublimation" effect, which can significantly reduce the adhesion of ice and frost.

[0031] Furthermore, the plasma wind acts directly on the surface of solid frost or fog droplets, causing them to become brittle and break down into micron-sized particles. The plasma wind then blows these particles away from the glass. Additionally, the plasma wind creates a 3-5cm wide "surface" pretreatment zone in front of the blade edge, requiring only a final sweep of the blade, thus avoiding scratches and wear on the glass caused by repeated scraping.

[0032] Therefore, the wiper structure 100 can direct the plasma wind generated by the ionization of air in the air duct 11 toward the windshield, thus allowing the OH groups in the plasma to be dispersed. - Active ions such as O3 break the hydrogen bonds of water molecules, reducing surface tension and decomposing the oil film into volatile small molecules. Simultaneously, the plasma wind blows away discrete water droplets and oxide particles from the windshield. Furthermore, before the wiper blades of the wiper structure 100 reach the water film, the water film has already been dispersed, thinned, or evaporated by the plasma wind, thus reducing wear on the wiper blades to some extent. Additionally, the plasma wind itself is cold plasma and requires no additional heating; it can pass through the active ions OH... - O3 breaks the molecular bonds on the surface of ice crystals, producing a local "micro-sublimation" effect, which can significantly reduce the adhesion of ice and frost.

[0033] According to some embodiments of the present invention, such as Figures 1-10 As shown, the plasma generating device 2 includes a first electrode 21 and a second electrode 22, which are spaced apart in the air duct 11, and an electric field is generated between the energized first electrode 21 and the second electrode 22.

[0034] The first electrode 21 and the second electrode 22 are spaced apart in the air duct 11. When the first electrode 21 and the second electrode 22 are placed in the air duct 11 and a voltage is applied, a strong electric field is formed between the first electrode 21 and the second electrode 22. This can ionize the gas molecules in the air duct 11 and generate plasma containing free electrons, positive and negative ions, excited state particles and active free radicals. When air passes through the air duct 11, plasma wind can be generated efficiently and continuously.

[0035] According to some embodiments of the present invention, such as Figure 1 As shown, the air duct 11 has an air inlet 111 and an air outlet 112, which are spaced apart in the width direction of the wiper frame 1. The first electrode 21 and the second electrode 22 are also spaced apart in the width direction of the wiper frame 1.

[0036] The air duct 11 has an air inlet 111 and an air outlet 112. The air inlet 111 provides sufficient air to the air within the ionization air duct 11. The plasma wind formed after the air ionization in the air duct 11 flows out from the air outlet 112, which can prevent the plasma wind from diffusing to other areas, reduce the outlet distance of the plasma wind, and reduce obstruction to the plasma wind, thereby increasing the flow velocity of the plasma wind. Moreover, the plasma wind formed after the air ionization in the air duct 11 flows out from the air outlet 112, which can concentrate a large amount of plasma wind in the air duct 11 area for a short time, thereby increasing the electric field strength of the plasma wind.

[0037] Furthermore, since the air duct 11 of the wiper frame 1 has an air inlet 111 and an air outlet 112, the plasma wind generated by the plasma generator 2 flows out from the air outlet 112, which can form a designated flow path for the plasma wind and prevent the plasma wind from diffusing to other areas, thereby concentrating the plasma wind on the wiper frame 1. The air inlet 111 can be formed into a long slot of 140mm in length and 9mm in width, and the air outlet 112 can be formed into a long slot of 160mm in length and 5mm in width.

[0038] The air inlet 111 and the air outlet 112 are spaced apart in the width direction of the wiper frame 1, which can guide the plasma wind to flow along the width direction of the wiper frame 1 and make the wind pass through the electric field in the air duct 11 more evenly, thereby improving the contact efficiency between plasma and air.

[0039] Furthermore, the first electrode 21 and the second electrode 22 are spaced apart in the width direction of the wiper frame 1, which can form multiple or continuous discharge regions in the width direction of the entire wiper frame 1, thereby making the electric field coverage area larger and the plasma generation more uniform.

[0040] According to some embodiments of the present invention, such as Figure 1 and Figure 6 As shown, the first electrode 21 is located at the air inlet 111, and the second electrode 22 is located at the air outlet 112.

[0041] The first electrode 21 is provided at the air inlet 111, and the second electrode 22 is provided at the air outlet 112. This can form a through-type high-voltage electric field, so that the air is ionized instantly when it enters the air duct 11 and can be continuously exposed to the plasma environment throughout the entire air duct 11.

[0042] According to some embodiments of the present invention, such as Figure 6 As shown, the distance between the first electrode 21 and the second electrode 22 in the width direction of the wiper frame 1 is d1, and d1 satisfies the relationship: 18mm≤d1≤25mm.

[0043] Specifically, if the distance d1 between the first electrode 21 and the second electrode 22 in the width direction of the wiper frame 1 is less than 18mm, the electric field strength is likely to be too high, which may easily cause arc discharge and damage the circuit. Therefore, the distance d1 between the first electrode 21 and the second electrode 22 in the width direction of the wiper frame 1 is set to be no less than 18mm.

[0044] If the distance d1 between the first electrode 21 and the second electrode 22 in the width direction of the wiper frame 1 is greater than 25mm, the ionization of air in the air duct 11 will require a higher voltage due to the larger distance, leading to increased energy consumption. Therefore, the distance d1 between the first electrode 21 and the second electrode 22 in the width direction of the wiper frame 1 is set to be no greater than 25mm.

[0045] The distance d1 between the first electrode 21 and the second electrode 22 in the width direction of the wiper frame 1 can be set to 19mm-24mm. For example, the distance d1 between the first electrode 21 and the second electrode 22 in the width direction of the wiper frame 1 can be set to 20mm, 22mm and 23mm, so that the discharge energy distribution can be more uniform.

[0046] According to some embodiments of the present invention, the first electrode 21 is a conductive needle.

[0047] Because the conductive needle has an extremely small radius of curvature, the discharge position is precisely controllable, and the energy distribution is concentrated, it can generate a very strong electric field concentration effect, thus producing a high electric field strength. This high electric field strength allows for more complete ionization of air molecules, thereby forming a stable region of plasma wind.

[0048] According to some embodiments of the present invention, the conductive needle is one of stainless steel needle and tungsten needle, the diameter of the conductive needle is D, D satisfies the relationship: 0.1mm≤D≤0.5mm, and the length of the conductive needle is L, L satisfies the relationship: 5mm≤L≤12mm.

[0049] The conductive needle can be made of stainless steel or tungsten. Due to their high melting point and corrosion resistance, stainless steel or tungsten needles are suitable for high-voltage discharge. Moreover, the high melting point of stainless steel or tungsten needles can prevent deformation of the conductive needle, thereby extending the service life of the first electrode 21.

[0050] Furthermore, the diameter D of the conductive needle should not be less than 0.1 mm. If the diameter D is less than 0.1 mm, the conductive needle is prone to bending and breakage due to resonance, and it also makes the manufacturing process more difficult. Therefore, the diameter D of the conductive needle should not be less than 0.1 mm.

[0051] Furthermore, the diameter D of the conductive needle should not exceed 0.5 mm. If the diameter D exceeds 0.5 mm, the wind resistance will double, the electric field enhancement factor will no longer increase, and the radius of curvature of the conductive needle will be too large, resulting in insufficient electric field strength and requiring a higher voltage to discharge. Therefore, the diameter D of the conductive needle should not exceed 0.5 mm.

[0052] The diameter D of the conductive needle can be set from 0.2mm to 0.4mm. For example, the diameter D of the conductive needle can be set to 0.2mm, 0.3mm and 0.4mm. In this way, the electric field strength of the conductive needle can be strong and the ionization efficiency can be high. At the same time, by ensuring sufficient electric field strength, it can adapt to the space inside the air duct 11 of the wiper frame 1.

[0053] Furthermore, the length L of the conductive needle should not be less than 5mm. If the length L of the conductive needle is less than 5mm, the conductive needle is easily blocked by the wiper frame 1, which makes it difficult for the conductive needle to discharge. Therefore, the length L of the conductive needle is set to be no less than 5mm.

[0054] The length L of the conductive needle should not exceed 12mm. If the length L exceeds 12mm, it may puncture the second electrode 22, inducing a reverse spark and causing the conductive needle to fracture due to fatigue under vibration. Therefore, the length L of the conductive needle should not exceed 12mm.

[0055] The length L of the conductive needle can be set from 6mm to 11mm. For example, the length L of the conductive needle can be set to 6mm, 7mm, and 10mm. When the length L of the conductive needle is 10mm, the ionization layer can cover 80% of the needle length, maximizing the ion yield. This ensures that the ionization zone of the conductive needle within the air duct 11 is deep enough to guarantee sufficient collisional ionization. At least a portion of the conductive needle can be completely exposed inside the air duct 11, allowing the conductive needle to form a uniform discharge gap with the second electrode 22. This ensures a strong electric field strength between the conductive needle and the second electrode 22, resulting in high efficiency in ionizing the air.

[0056] According to some embodiments of the present invention, such as Figure 19 and Figure 20 As shown, the conductive needle includes a needle body 211 and a needle tip 212. The needle tip 212 is connected to one end of the needle body 211, and the cross-sectional area of ​​the needle tip 212 decreases in the direction away from the needle body 211. The length of the needle body 211 is L1, and the length of the needle tip 212 is L2. L1 and L2 satisfy the relationship: 0.2≤L2 / L1≤0.3.

[0057] The conductive needle is mainly composed of a needle body 211 and a needle tip 212. The needle tip 212 is connected to one end of the needle body 211 and penetrates into the air duct 11 of the wiper frame 1, so that a strong electric field can be generated between the needle tip 212 and the second electrode 22.

[0058] Furthermore, the cross-sectional area of ​​the needle tip 212 decreases in the direction away from the needle body 211, so that the radius of curvature of the needle tip 212 is small, which can rapidly enhance the electric field and concentrate a higher electric field on the needle tip 212.

[0059] Furthermore, if the ratio of the length L2 of the needle tip 212 to the length L1 of the needle body 211 is less than 0.2, the length of the needle tip 212 will be too small, making it difficult for the needle tip 212 to discharge. Therefore, the ratio of the length L2 of the needle tip 212 to the length L1 of the needle body 211 is set to be no less than 0.2.

[0060] If the ratio of the length L2 of the needle tip 212 to the length L1 of the needle body 211 is greater than 0.3, the length of the needle tip 212 will be too long, making it easy for the needle tip 212 to bend under vibration or force. Therefore, the ratio of the length L2 of the needle tip 212 to the length L1 of the needle body 211 is set to be no greater than 0.3.

[0061] The ratio of the length L2 of the needle tip 212 to the length L1 of the needle body 211 can be set to 0.2 and 0.3, which can ensure a strong electric field strength, effectively ionize the air, achieve high ionization efficiency, extend the service life of the conductive needle, and ensure a certain degree of corrosion resistance.

[0062] According to some embodiments of the present invention, such as Figure 19 and Figure 20 As shown, the needle tip 212 is connected to one end of the needle body 211 facing the second electrode 22, and the needle tip 212 extends toward the second electrode 22.

[0063] Specifically, when the needle tip 212 extends directly towards the second electrode 22, the electric field lines travel perpendicularly from the needle tip 212 to the second electrode 22 without deflection, effectively shortening the discharge distance and thus improving the efficiency of air ionization. Furthermore, if the needle tip 212 is not directly facing the second electrode 22, the electric field tends to concentrate in non-target areas, reducing the efficiency of air ionization.

[0064] According to some embodiments of the present invention, the second electrode 22 is one or more of a conductive grid, a conductive ring, a conductive mesh, and a conductive wire.

[0065] Specifically, conductive grids, conductive rings, conductive meshes, and conductive wires can all be used as conductive conductors, thus serving as the second electrode 22. The second electrode 22 can also be configured by combining two or more of the conductive grids, conductive rings, conductive meshes, and conductive wires, thereby enabling the second electrode 22 to be adapted to the first electrode 21 formed by the conductive needle to generate an electric field. For example, the first electrode 21 is the positive electrode, and the second electrode 22 is the negative electrode.

[0066] According to some embodiments of the present invention, such as Figure 9 As shown, the second electrode 22 is a conductive grid with a thickness of t, which satisfies the relationship: 0.18mm < t < 0.5mm. The width of the conductive grid is w, which satisfies the relationship: 2.0mm ≤ w ≤ 3.46mm.

[0067] If the thickness t of the conductive grid is less than 0.18 mm, the strength of the conductive grid will be reduced, making it more susceptible to deformation or damage from vibration or external forces. Therefore, the thickness t of the conductive grid should be greater than 0.18 mm.

[0068] If the thickness t of the conductive grid is greater than 0.5mm, it will increase the volume of the conductive grid and increase the wind resistance. Since the space of the wiper frame 1 is limited, the conductive grid cannot be installed on the wiper frame 1. Therefore, the thickness t of the conductive grid is set to be less than 0.5mm.

[0069] The thickness t of the conductive grid can be set from 0.19 mm to 0.4 mm. For example, the thickness t of the conductive grid can be set to 0.19 mm, 0.20 mm, and 0.3 mm. This ensures that the conductive grid has sufficient strength and reduces wind resistance. At the same time, due to the limited space of the wiper frame 1, the conductive grid can be ensured to have a reasonable assembly thickness, which facilitates the assembly of the conductive grid onto the wiper frame 1.

[0070] Furthermore, if the width w of the conductive grid is less than 2.0 mm, the conductive grid will not be able to collect the plasma generated by the first electrode 21. Therefore, the width w of the conductive grid is set to be no less than 2.0 mm. If the width w of the conductive grid is greater than 3.46 mm, it will shield the electric field between the first electrode 21 and the conductive grid. Shielding will lead to a weakening of the plasma wind intensity. Therefore, the width w of the conductive grid is set to be no greater than 3.46 mm.

[0071] The width w of the conductive gate can be set from 2.5 mm to 3.4 mm. For example, the width w of the conductive gate can be set to 2.6 mm, 3.2 mm and 3.4 mm. In this way, the distribution of the electric field can be guaranteed, and the electric field between the first electrode 21 and the conductive gate can be avoided.

[0072] Furthermore, the second electrode 22 can be set as a copper grid. Copper has the advantages of good conductivity, easy processing and corrosion resistance. There is a notch 6 at the upper end of the copper grid. The notch 6 can ensure that the second connecting line 24 can be fixed and can have a certain contact with the second connecting line 24 to ensure connection. The direction of the copper grid is perpendicular to the direction of plasma air flow, which can reduce the resistance of plasma air flow. At the same time, the design of the spacing between adjacent copper grids is to ensure that the air energy flows out smoothly while taking into account the uniformity of the electric field, which can also make the speed of the air outlet 112 relatively uniform.

[0073] According to some embodiments of the present invention, such as Figure 1 As shown, there are multiple first electrodes 21, which are distributed at intervals along the length of the wiper frame 1 within the air duct 11. There are also multiple second electrodes 22, which are distributed at intervals along the length of the wiper frame 1.

[0074] The multiple first electrodes 21 are spaced apart along the length of the wiper frame 1 within the air duct 11. This ensures that the corona regions generated by each first electrode 21 do not overlap, guaranteeing sufficient electric field strength and thus improving the efficiency of air ionization. If the corona regions overlap, the electric field strength will decrease, which will also weaken the air ionization.

[0075] Furthermore, the multiple second electrodes 22 are spaced apart along the length of the wiper frame 1, which can prevent air from being broken down, thus ensuring the safety of ionization.

[0076] According to some embodiments of the present invention, the distance between two adjacent first electrodes 21 is d2, and d2 satisfies the relationship: 3.3mm≤d2≤5mm, and the distance between two adjacent second electrodes 22 is d3, and d3 satisfies the relationship: 3.7mm≤d3≤6mm. The plurality of first electrodes 21 and the plurality of second electrodes 22 are staggered along the length direction of the wiper frame 1.

[0077] If the distance d2 between two adjacent first electrodes 21 is less than 3.3 mm, the corona regions generated by the two adjacent first electrodes 21 will overlap. The overlapping corona regions will reduce the electric field strength and weaken the ionization effect. Therefore, the distance d2 between two adjacent first electrodes 21 is set to be no less than 3.3 mm.

[0078] If the distance d2 between two adjacent first electrodes 21 is greater than 5mm, it will reduce the number of first electrodes 21 on the wiper frame 1, reduce the electric field strength, and reduce the efficiency of the first electrode 21 in ionizing air. Therefore, the distance d2 between two adjacent first electrodes 21 should not be greater than 5mm.

[0079] The distance d2 between two adjacent first electrodes 21 can be set to 3.4 mm to 4 mm. For example, the distance d2 between two adjacent first electrodes 21 can be set to 3.5 mm, 3.8 mm and 4 mm. In this way, the corona regions generated by two adjacent first electrodes 21 can be avoided from overlapping, thereby ensuring the electric field strength and the ionization effect.

[0080] Furthermore, if the distance d3 between two adjacent second electrodes 22 is less than 3.7 mm, it will result in the distance between the two adjacent second electrodes 22 being too narrow, which will cause the air to be broken down. Therefore, the distance d3 between two adjacent second electrodes 22 is set to be no less than 3.7 mm.

[0081] If the distance d3 between two adjacent second electrodes 22 is greater than 6mm, the number of second electrodes 22 on the wiper frame 1 will be reduced, and the electric field strength will also be reduced. Therefore, the distance d3 between two adjacent second electrodes 22 is set to be no greater than 6mm.

[0082] The spacing d3 between two adjacent second electrodes 22 can be set to 3.8 mm to 5 mm. For example, the spacing d3 between two adjacent second electrodes 22 can be set to 3.9 mm, 4 mm and 5 mm. This ensures that the air is not broken down, thereby improving the safety of ionization.

[0083] Furthermore, the multiple first electrodes 21 and multiple second electrodes 22 are staggered along the length of the wiper frame 1, which can prevent the second electrodes 22 from blocking the plasma wind generated at the first electrodes 21, thus facilitating the flow of plasma wind from the air outlet 112.

[0084] Furthermore, the current density between two adjacent first electrodes 21 should be less than 5 mm. Exceeding this current density will cause a short circuit and accelerate aging. The current density between two adjacent second electrodes 22 should be less than 6 mm. Exceeding this current density will cause a short circuit and accelerate aging.

[0085] Furthermore, the distance between the first electrode 21 and the second electrode 22 is between 18mm and 25mm. The radius of curvature of the needle tip 212 is 0.1mm. To generate plasma wind, the voltage must meet certain values ​​to ionize the air and generate a certain amount of ion wind. Calculations show that the minimum voltage V required for air ionization is ≥15.4KV. If the voltage is too high, plasma wind will not be generated, and an electric arc will occur, damaging the electrodes and posing a safety hazard. Therefore, the voltage must be controlled within a certain range. Calculations show that the minimum voltage for arc ignition is V≤27.9KV. Therefore, 15.4KV≤V≤27.9KV is calculated. To ensure stable operation of the plasma generator 2, the voltage range is set to 18KV to 25KV.

[0086] According to some embodiments of the present invention, such as Figure 1 As shown, there are multiple first electrodes 21 and multiple second electrodes 22. The wiper structure 100 also includes a bracket 3, the wiper frame 1 is disposed on the bracket 3, and the bracket 3 is provided with a conductive structure. The plasma generating device 2 also includes a first connecting line 23 and a second connecting line 24. The first connecting line 23 is connected to multiple first electrodes 21, the second connecting line 24 is connected to multiple second electrodes 22, and the first connecting line 23 and the second connecting line 24 are electrically connected to the conductive structure respectively.

[0087] The wiper frame 1 is mounted on the bracket 3, which provides an installation position for the wiper frame 1, thus facilitating its installation. Furthermore, the first connecting line 23 is connected to multiple first electrodes 21, enabling electrical connection between the multiple first electrodes 21 and the first connecting line 23.

[0088] Furthermore, the second connecting line 24 is connected to multiple second electrodes 22, enabling electrical connection between the multiple second electrodes 22 and the second connecting line 24. Moreover, the first connecting line 23 and the second connecting line 24 are respectively electrically connected to a conductive structure, thereby enabling the first electrode 21 to be electrically connected to the conductive structure of the support 3 via the first connecting line 23, and also enabling the second electrode 22 to be electrically connected to the conductive structure of the support 3 via the second connecting line 24, thus forming a quick-connect interface on the support 3.

[0089] According to some embodiments of the present invention, such as Figure 12 As shown, the conductive structure includes: a positive power supply terminal 31, a negative power supply terminal 32, a first terminal 33, and a second terminal 34. One end of the first connecting wire 23 is inserted into the first terminal 33, and the first terminal 33 is connected to the positive power supply terminal 31. One end of the second connecting wire 24 is inserted into the second terminal 34, and the second terminal 34 is connected to the negative power supply terminal 32.

[0090] One end of the first connecting wire 23 is inserted into the first plug-in terminal 33, which facilitates the connection of the first connecting wire 23 to the positive power supply plug-in terminal 31 through the first plug-in terminal 33. One end of the second connecting wire 24 is inserted into the second plug-in terminal 34, which facilitates the connection of the second connecting wire 24 to the negative power supply plug-in terminal 32 through the second plug-in terminal 34.

[0091] Furthermore, the first plug-in terminal 33 and the second plug-in terminal 34 can be set with different shapes. For example, the first plug-in terminal 33 can be set as a rectangle and the second plug-in terminal 34 can be set as a square. The first plug-in terminal 33 and the second plug-in terminal 34 can also be set with different colors. For example, the first plug-in terminal 33 can be set as red and the second plug-in terminal 34 can be set as red. In this way, reverse power connection can be prevented from disrupting the formation of plasma wind.

[0092] According to some embodiments of the present invention, such as Figure 2 As shown, there are two wiper frames 1 and two plasma generators 2. The two wiper frames 1 correspond one-to-one with the two plasma generators 2. The wiper frames 1 are connected to both sides of the bracket 3. Both sides of the bracket 3 are provided with a first plug-in end 33 and a second plug-in end 34.

[0093] The wiper frame 1 and the plasma generator 2 are both present in pairs, which further enhances the ionization effect of the air inside the air duct 11 of the wiper frame 1. Furthermore, the wiper frame 1 is connected to both sides of the bracket 3, which provides support for the wiper frame 1, facilitating its installation. Additionally, both sides of the bracket 3 are provided with a first insertion end 33 and a second insertion end 34, thus forming two quick-connect interfaces on the bracket 3, making its structure more compact and installation more convenient.

[0094] According to some embodiments of the present invention, such as Figure 1 As shown, the air duct 11 has an air inlet 111 and an air outlet 112, and the wiper frame 1 has an inclined guide lip 9 at the edge of the air outlet 112.

[0095] Among them, the wiper frame 1 has an inclined guide lip 9 at the edge of the air outlet 112, which can prevent the plasma air from separating at the edge of the air outlet and flowing to other areas, and can also control the air outlet direction to accurately deliver the plasma air to the target area (such as the windshield of a vehicle).

[0096] According to some embodiments of the present invention, such as Figure 1 As shown, the guide lip 9 is located at the upper edge and / or lower edge of the air outlet 112.

[0097] The upper edge of the air outlet 112 can be provided with a guide lip 9, or the lower edge of the air outlet 112 can be provided with a guide lip 9, or both the upper and lower edges of the air outlet 112 can be provided with guide lips 9, thereby changing the direction of the plasma air outlet and having a local deflection effect, which will generate a deflection angle, so that the plasma air can be blown toward the surface of the vehicle's windshield.

[0098] According to some embodiments of the present invention, such as Figure 1 As shown, the guide lip 9 is inclined downward relative to the opening direction of the air outlet 112, and the guide lip 9 and the opening direction of the air outlet 112 form an angle α, which satisfies the relationship: 30°≤α≤50°.

[0099] If the angle α formed by the opening direction of the guide lip 9 and the air outlet 112 is less than 30°, the plasma air cannot be deflected and cannot accurately direct the plasma airflow towards the windshield. Therefore, the angle α formed by the opening direction of the guide lip 9 and the air outlet 112 should not be less than 30°.

[0100] If the angle α formed by the opening direction of the guide lip 9 and the air outlet 112 is greater than 50°, the plasma airflow will be excessively compressed downwards and will not be able to accurately direct the plasma airflow towards the windshield. Therefore, the angle α formed by the opening direction of the guide lip 9 and the air outlet 112 should be no less than 50°.

[0101] The angle α formed by the guide lip 9 and the opening direction of the air outlet 112 can be set to 35° to 49°. For example, if the angle α formed by the guide lip 9 and the opening direction of the air outlet 112 is 45°, the guide lip 9 will be deflected downwards by 45°, which will generate a deflection angle, allowing the plasma wind to blow onto the surface of the vehicle's windshield.

[0102] According to some embodiments of the present invention, such as Figures 5-13 As shown, the wiper frame 1 has a first slot 12 at its bottom and the bracket 3 has a second slot 35 at its bottom. The wiper structure 100 also includes a snap-fit ​​member 4 and a wiper blade 5. The snap-fit ​​member 4 is located at the end of the wiper frame 1 away from the bracket 3. The bottom of the snap-fit ​​member 4 has a third slot 41. The first slot 12, the second slot 35 and the third slot 41 are connected. The wiper blade 5 is inserted into the first slot 12, the second slot 35 and the third slot 41.

[0103] The wiper frame 1 has a first slot 12 at its bottom, which provides installation space for other parts. The bracket 3 has a second slot 35 at its bottom, which also provides installation space for other parts.

[0104] Furthermore, the snap-fit ​​4 is located at the end of the wiper frame 1 away from the bracket 3, so that the snap-fit ​​4 can be snapped into the end of the wiper frame 1 away from the bracket 3, thereby facilitating the installation and removal of the snap-fit ​​4 and the wiper frame 1.

[0105] Furthermore, a third slot 41 is provided at the bottom of the snap-fit ​​component 4, which provides installation space for other parts. The first slot 12, the second slot 35, and the third slot 41 are connected, which can further increase the installation space. The wiper blade 5 is inserted into the first slot 12, the second slot 35, and the third slot 41, thereby facilitating the installation of the wiper blade 5.

[0106] According to some embodiments of the present invention, such as Figure 1 and Figure 22 As shown, the wiper blade 5 includes: a wiper blade 51, a first spring 52 and a second spring 53. The first spring 52 and the second spring 53 are both inserted into the first slot 12, the second slot 35 and the third slot 41. The first spring 52 and the second spring 53 are spaced apart in the width direction of the first slot 12. The wiper blade 51 is inserted between the first spring 52 and the second spring 53.

[0107] The first spring piece 52 and the second spring piece 53 are both inserted into the first slot 12, the second slot 35, and the third slot 41, which provide installation space for the first spring piece 52 and the second spring piece 53. The first spring piece 52 and the second spring piece 53 are spaced apart in the width direction of the first slot 12, making efficient use of the space and facilitating their installation. Furthermore, the scraper strip 51 is inserted between the first spring piece 52 and the second spring piece 53, providing clamping force and facilitating its installation and removal.

[0108] Furthermore, during assembly, firstly, the bracket 3 is inserted into the middle position between the first spring piece 52 and the second spring piece 53, and then the bracket 3 is fixedly connected to the first spring piece 52 and the second spring piece 53 by ultrasonic welding. Then, the two wiper frames 1 are respectively inserted onto the left and right sides of the bracket 3, also fitting with the first spring piece 52 and the second spring piece 53 to form left and right guide vanes. Finally, the snap-fit ​​pieces 4 at both ends of the wiper frame 1 are pressed into the first spring piece 52 and the second spring piece 53, and the buckles on the snap-fit ​​pieces 4 are aligned with the square holes of the spring pieces to complete the assembly. The wiper blade 51 has a first slot 12, a second slot 35, and a third slot 41. The first spring piece 52 and the second spring piece 53 are embedded in the first slot 12, the second slot 35, and the third slot 41, enabling rapid assembly of the first spring piece 52 and the second spring piece 53. Meanwhile, the two wiper frames 1 can serve as carriers for the plasma generator 2. Nine pairs of second electrode mounting slots 8 are pre-drilled at fixed intervals on their leeward side, and eight needle-shaped first electrode mounting holes 7 are opened at corresponding positions on the windward side. The first electrode mounting holes 7 are precisely located between two adjacent copper grid electrodes. The copper grid electrodes are pressed into the second electrode mounting slots 8 with an interference fit, and the first electrodes 21 are also inserted into the first electrode mounting holes 7 with an interference fit, ensuring no loosening. Subsequently, the copper grids of the same polarity and the first electrodes 21 are connected in parallel using first connecting wires 23 and second connecting wires 24. The first connecting wires 23 and 24 run along the inner wall of the wiper frame 1 and converge at the connection point with the bracket 3 to form a power connector, creating a quick-connect interface.

[0109] The working principle of the wiper structure 100 is as follows: Based on traditional wipers, it is optimized while retaining the original wiping function of the wiper blades. A plasma generator 2 is integrated into the wiper frame 1 containing the wiper blades. The plasma generator 2 acts as an ion wind generator, using high-voltage ionization of air to form plasma. Driven by a high-voltage electric field, the plasma moves directionally and collides with the air, generating a macroscopic ion wind. Utilizing the characteristics of the ion wind, the dynamics / surface chemical effects of the high-voltage ionization-ion wind are superimposed on the mechanical wiping of traditional wipers. This disrupts the continuity of the water film before it reaches the rubber blade edge, significantly reducing mechanical load, improving cleanliness, and expanding adaptability to extreme weather. Simultaneously, the characteristics of the plasma wind can replace the heating busbar. Compared to the heating busbar, it has a simpler, thinner structure, is easier to integrate, consumes less energy, has a faster response speed, almost instantaneous start-up, no thermal inertia, and can also remove dust and oil stains.

[0110] Furthermore, with advancements in materials and manufacturing processes, the plasma generator 2 will be integrated into the wiper blade 51, bringing the air outlet 112 closer to the glass surface for even better performance. Based on continuous validation of new materials, the current wiper structure 100 will be replaced by materials with better performance and higher ionization levels, achieving stronger and more efficient ionization, thereby further enhancing the intensity and speed of the plasma wind.

[0111] According to a second aspect of the present invention, a wiper system includes a drive structure and a wiper structure 100 as described above. The wiper frame 1 is connected to the drive structure and can move under the drive of the drive structure.

[0112] The drive structure provides power to the wiper frame 1, which facilitates the movement of the wiper frame 1 to remove rainwater or frost from the surface of the vehicle's windshield.

[0113] Furthermore, when the drive structure moves the wiper frame 1 in the wiper structure 100, the plasma wind generated in the wiper structure 100 can blow away discrete water droplets and oxide particles from the windshield. The rubber blade of the wiper structure 100 only needs light pressure to remove the residual liquid film. Moreover, before the blade of the wiper structure 100 reaches the water film, the water film has already been dispersed, thinned, or evaporated by the plasma wind, thereby reducing the wear of the blade of the wiper structure 100 to a certain extent.

[0114] A vehicle according to a third aspect of the present invention includes: the wiper system of the above embodiments, or the wiper structure 100 described above.

[0115] The wiper system utilizes the wiper frame 1 and plasma generator 2 in the wiper structure 100. The plasma generator 2 is placed inside the air duct 11 of the wiper frame 1. When the drive structure drives the wiper frame 1 in the wiper structure 100 to move, the plasma generator 2 ionizes the air in the air duct 11 to form plasma wind. At the same time, the plasma wind blows towards the windshield of the vehicle. In this way, the plasma wind can blow away discrete water droplets and oxide particles from the windshield, thereby removing the residual liquid film from the windshield.
