Description

Technical Field

[0001] The present disclosure relates to a windshield washer fluid spraying system and a vehicle, belonging to the technical field of vehicles and their accessories. Background Art

[0002] Vehicles are equipped with a windshield washer fluid spraying system, which maintains the cleanliness of the windshield through the spraying and washing of windshield washer fluid in cooperation with the windshield wiper to ensure clear driving visibility. In daily use, various contaminants sometimes adhere to the surface of the windshield, including road oil stains, insect residues, tree sap, bird droppings, and dust particles in the air, etc. Traditional windshield washer fluid mainly relies on the combination of chemical cleaners and surfactants to decompose these stains. However, in terms of cleaning oil stains, the dissolution rate of traditional windshield washer fluid for mineral oil and grease contaminants is relatively slow. Especially in the low-temperature environment in winter, the reduced fluidity of the windshield washer fluid leads to insufficient penetration ability, and multiple sprayings are often required to achieve a basic cleaning effect. For stubborn stains such as gum stains, traditional windshield washer fluid often cannot completely dissolve them, and manual cooperation with a scraper is required, which is time-consuming and may damage the glass surface.

[0003] In rainy, snowy, and freezing weather, the performance defects of existing windshield washer fluid are even more obvious. The windshield washer fluid sprayed in a low-temperature environment is likely to form a water film on the glass surface, and its surface tension is not sufficient to quickly spread and penetrate to the interface between the ice layer and the glass, resulting in low de-icing efficiency. At the same time, when ordinary windshield washer fluid lacks an effective antifreeze or the proportion of the antifreeze is insufficient, the pipeline and nozzle are prone to icing and blockage, completely losing the cleaning function and affecting driving safety.

[0004] Therefore, the traditional windshield washer fluid spraying system is difficult to meet the requirements of modern driving for efficient cleaning under low-temperature climates and polluted conditions. Summary of the Invention

[0005] To solve the above technical problems of the traditional windshield washer fluid spraying system, the present disclosure provides a windshield washer fluid spraying system and a vehicle having the windshield washer fluid spraying system, which can effectively remove various stubborn stains such as oil stains, gum stains, and insect corpses, and can reliably clean even in low-temperature climates such as ice and snow, and improve the effect and service life of the windshield wiper, ensuring clear driving visibility and driving safety.

[0006] Specifically, in the first aspect of the present disclosure, a windshield washer fluid spraying system for a vehicle is provided, including: a liquid storage part for storing windshield washer fluid therein; a spraying port part for ejecting and spraying the windshield washer fluid onto the windshield; and a delivery pipeline provided between the liquid storage part and the spraying port part for delivering the windshield washer fluid, wherein the delivery pipeline includes a heating section provided with a heating part, the heating part being capable of heating the windshield washer fluid flowing through the heating section, and wherein the heating section of the delivery pipeline is a rigid section.

[0007] According to the windshield washer fluid spraying system with the above composition, by configuring a heating section in the delivery pipeline, efficient directional heating of the delivered windshield washer fluid can be achieved, rapidly raising the temperature of the windshield washer fluid to the optimal cleaning range, and then discharging and spraying the heated windshield washer fluid onto the windshield, significantly enhancing the dissolution and peeling ability for oil stains, glue stains, insect corpses, and thin ice layers. Moreover, it can effectively prevent freezing at the spraying port in a low-temperature environment, ensuring the stable operation of the cleaning function in extreme weather and providing a clear vision environment for the driver. Additionally, the heating section adopts a rigid pipeline, which has stronger structural stability, guarantees the stable energy supply between the heating element and the windshield washer fluid, provides a firm support for the heating element, ensures uniform heat transfer, and guarantees the stability of the heating efficiency.

[0008] Preferably, in the windshield washer fluid spraying system of the first aspect above, it further includes: a water pump section, which is arranged in the delivery pipeline and is used to pump the windshield washer fluid from the liquid storage section to the spraying port. Among them, the heating section is arranged on the way between the water pump section and the spraying port.

[0009] According to the windshield washer fluid spraying system with the above composition, by arranging the heating section between the water pump section and the spraying port, the windshield washer fluid enters the heating section after being pressurized by the water pump section. The pressurized windshield washer fluid helps to achieve rapid and uniform heat transfer. The post-positioned heating section avoids the continuous erosion of the pump body by high-temperature windshield washer fluid, reduces the working temperature of the pump body, delays the aging process of the seals and impellers of the water pump section, and significantly extends the service life of the pump body. The heated windshield washer fluid is ejected at high speed from the spraying port under high-pressure drive. The synergistic effect of high temperature and high pressure makes the windshield washer fluid atomize more fully and the water column more powerful, expanding the cleaning coverage area. At the same time, high temperature can enhance the activity of the cleaner, and combined with the high-pressure impact force, it can effectively peel off stubborn stains, reduce the number of times the windshield wiper scrapes, and extend the service life of the windshield wiper.

[0010] Preferably, in the windshield washer fluid spraying system of the first aspect above, on the way between the water pump section and the spraying port, the heating section is arranged at a position closer to the spraying port than the water pump section.

[0011] According to the windshield washer fluid spraying system with the above composition, by arranging the heating section between the water pump section and the spraying port and at a position closer to the spraying port, an optimized layout of "short-range heating - immediate spraying" can be formed. The shortened distance from the heating section to the spraying port can effectively reduce the conduction loss of heat in the pipeline, ensure that the windshield washer fluid quickly acts on the glass surface after reaching the optimal cleaning temperature, significantly reduce the time for the windshield washer fluid to maintain a high-temperature state in the pipeline, and significantly improve the heat utilization rate.

[0012] Preferably, in the windshield washer fluid spraying system according to the first aspect above, the heating section includes: a steel pipe portion as the innermost layer, which is in contact with the windshield washer fluid; a heating portion disposed outside the steel pipe portion; a heat insulation portion disposed outside the heating portion; and an aluminum foil portion disposed outside the heat insulation portion.

[0013] According to the windshield washer fluid spraying system having the above structure, the multi-layer structure of the heating section can achieve efficient, safe and durable heating performance through the synergistic effect of each functional layer. The innermost steel pipe portion is made of a high thermal conductivity metal material and is in direct contact with the windshield washer fluid, ensuring that heat is quickly transferred to the windshield washer fluid. Moreover, the rigid characteristics of the steel pipe portion can provide a stable support for the heating section, resist the vibration and impact during vehicle operation, and avoid the risk of deformation or leakage caused by the softening of the flexible pipeline due to high temperature, significantly improving the system reliability. The heating portion is disposed outside the steel pipe portion, and the heat acts directly on the windshield washer fluid through metal conduction. The surrounding heating ensures a uniform temperature distribution of the windshield washer fluid, improves the heating response speed, and enables the windshield washer fluid to reach the optimal cleaning temperature in a short time. The heat insulation portion wraps the heating portion, effectively blocking the heat from dissipating outward and preventing the heating portion from harming the outside, maintaining the internal temperature stability of the heating section, reducing energy loss, improving heating efficiency, ensuring that the windshield washer fluid remains at a high temperature during transportation, and at the same time reducing the overall energy consumption of the system. The outermost aluminum foil portion not only provides physical protection but also reflects external heat, further reducing heat loss, protecting the heat insulation portion from being scratched, and preventing the material of the heat insulation portion from causing harm to the human body. The multi-layer configuration of the heating section of the present disclosure realizes efficient heating, reliable protection and energy-saving operation of the windshield washer fluid, and has excellent heating efficiency, durability and safety.

[0014] Preferably, in the windshield washer fluid spraying system according to the first aspect above, in the heating section, the heating portion is a resistance wire, and the heat insulation portion is heat insulation cotton.

[0015] According to the windshield washer fluid spraying system having the above structure, the resistance wire as the heating portion can be closely wound outside the steel pipe portion, evenly covering the cross-section of the windshield washer fluid flow, ensuring that heat is quickly conducted to the windshield washer fluid. The heat insulation cotton as the heat insulation portion wraps the resistance wire and the steel pipe portion, and uses its low thermal conductivity characteristics to block the heat from diffusing outward, concentrating the heat energy toward the windshield washer fluid inside the steel pipe portion, significantly improving the energy utilization rate. Moreover, the soft texture of the heat insulation cotton can absorb the mechanical stress caused by vehicle vibration on the resistance wire, preventing the resistance wire from breaking due to long-term vibration, and improving the system reliability.

[0016] Preferably, in the windshield washer fluid spraying system according to the first aspect above, the steel pipe portion, the heating portion, the heat insulation portion and the aluminum foil portion are arranged adjacent to each other in sequence.

[0017] According to the windshield washer fluid spraying system with the above structure, the heating section adopts an integrated structure design with four layers closely attached, without setting a redundant layer in the middle or a redundant layer on the outermost side, which can achieve a more compact structure and cost reduction.

[0018] Preferably, in the windshield washer fluid spraying system of the first aspect above, the part of the delivery pipeline other than the heating section is a hose section, and the hose section and the heating section are connected into one body via an electronic quick connector.

[0019] According to the windshield washer fluid spraying system with the above structure, the delivery pipeline is divided into a rigid heating section and a flexible hose section, and modular connection is achieved through an electronic quick connector, thus forming a pipeline system combining rigidity and flexibility. The flexible hose section can be freely bent according to the vehicle structure to flexibly adapt to the complex engine compartment layout. The fixed installation of the rigid heating section ensures the stable operation of the heating part such as the resistance wire. The seamless connection of the two through the quick connector not only retains the high-efficiency heat conduction characteristics of the rigid section but also endows the overall system with flexible adaptation ability. Moreover, the electronic quick connector can also achieve tool-free disassembly and assembly, plug-and-play, simple assembly. When the heating section needs maintenance or replacement, it can be quickly separated and reset, significantly shortening the maintenance time. At the same time, it can also be electronically controlled, which helps with safety assurance.

[0020] Preferably, in the windshield washer fluid spraying system of the first aspect above, it further includes: a control unit, the control unit can receive the user's instruction and can receive the ambient temperature information. Among them, the control unit controls the heating part of the heating section in response to the received user's instruction to perform one of turning on heating, turning off heating, increasing or decreasing the heating current, and / or among them, the control unit controls the heating part of the heating section based on the received ambient temperature information so that the windshield washer fluid is heated and maintained within a predetermined temperature range.

[0021] According to the windshield washer fluid spraying system with the above structure, a control unit that can be manually or automatically controlled is introduced into the windshield washer fluid spraying system, which can achieve precise and intelligent control of the cleaning process, meet the user's personalized needs through interaction with the user, and meet the automation requirements by controlling based on the ambient temperature.

[0022] Preferably, in the windshield washer fluid spraying system of the first aspect above, it further includes: a monitoring unit, the monitoring unit monitors the open circuit of the electronic quick connector and sends the monitored open circuit signal to the control unit.

[0023] According to the windshield washer fluid spraying system with the above structure, by adding a monitoring unit to the windshield washer fluid spraying system, it is possible to achieve real-time monitoring and intelligent feedback of the open circuit state of the electronic quick connector. The monitoring unit continuously monitors the electrical conductivity of the electronic quick connector. Once it detects an open circuit caused by loose, detached or poor contact of the connector, it can immediately send a signal to the control unit. This real-time feedback can ensure that the heating function and the start / stop of the water pump unit are always in a controllable state, avoiding heating interruption or windshield washer fluid leakage caused by physical connection failure, and improving reliability and safety.

[0024] The second aspect of the present disclosure provides a vehicle, which is equipped with the windshield washer fluid spraying system described in the first aspect. Due to the configuration of the windshield washer fluid spraying system in the first aspect, the vehicle in the second aspect can also achieve the above various technical effects of the windshield washer fluid spraying system in the first aspect.

[0025] The basic structure and technical effects of the windshield washer fluid spraying system of the present disclosure and the vehicle equipped with this windshield washer fluid spraying system have been described above. Next, the windshield washer fluid spraying system of the present disclosure will be described in more detail with reference to the drawings for easier understanding. Description of the Drawings

[0040] Hereinafter, the technical solution of the present invention will be described more clearly by describing the specific embodiments of the present invention with reference to the accompanying drawings.

[0041] It should be noted that the drawings in the present invention are only schematic diagrams simply shown for clearly showing the parts related to the solution of the present invention, and do not show some non-essential parts that may exist. Therefore, these drawings should not be construed as limiting the present invention, and they may be different from the actual structure during use. In addition, it should also be understood that the terms "upper", "lower", "left", "right", "front", "rear", etc. indicating orientation or position that may appear in the following description are for the purpose of convenience of description and are not restrictive. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted below.

[0042] Figure 1 shows a schematic block diagram of a windshield washer fluid spraying system according to an embodiment of the present disclosure; and

[0043] Figure 2 shows Figure 1 a schematic cross-sectional view of the configuration of the heating section 40 in the windshield washer fluid spraying system shown in

[0044] The windshield washer fluid spraying system of the present disclosure is provided in a vehicle and is used to cooperate with a windshield wiper to clean the windshield of the vehicle, etc. It can effectively remove various stubborn stains such as oil stains, glue stains, and insect corpses, and can also be reliably cleaned even in low-temperature climates such as ice and snow, and improve the effect and service life of the windshield wiper, ensuring clear driving vision and driving safety.

[0045] As Figure 1 shown, the windshield washer fluid spraying system for a vehicle according to an embodiment of the present disclosure includes: a liquid storage part 10 for storing windshield washer fluid therein; a spraying port part 20 for ejecting and spraying the windshield washer fluid onto the windshield; and a delivery pipeline 30 provided between the liquid storage part 10 and the spraying port part 20 for delivering the windshield washer fluid. The delivery pipeline 30 includes a heating section 40 provided with a heating part that can heat the windshield washer fluid flowing through the heating section 40, and wherein the heating section 40 of the delivery pipeline 30 is a rigid section.

[0046] The liquid storage part 10 can be integrated as a cylindrical or flat container in the area near the windshield at the front of the engine compartment, with a filling port reserved at the top for the user to directly and quickly replenish the windshield washer fluid. The bottom of the liquid storage part 10 can be connected to the flexible part of the delivery pipeline through various connection methods such as threaded interfaces to ensure that the windshield washer fluid can stably flow into the delivery pipeline by gravity and the suction action of the water pump part.

[0047] The spraying orifice 20 can be a nozzle, hidden inside the front edge deflector of the engine hood or in the base of the wiper pivot, and can be symmetrically arranged in multiple numbers. Each nozzle is installed at a predetermined inclination angle to ensure that the sprayed windshield washer fluid can cover the entire windshield surface, including the working range of the wiper and the corner areas.

[0048] The delivery pipeline 30 is the passage through which the windshield washer fluid flows. After being led out from the bottom of the liquid storage part 10, it is first connected to the water pump part through a flexible hose section. By utilizing the bendability of the hose, it bypasses components such as the engine and suspension, adapting to the complex mechanical structure in the engine compartment. After leaving the water pump part, the delivery pipeline enters the section provided with the rigid heating section 40. This rigid section 40 can adopt a metal pipeline with heat insulation material wrapped on the surface, which not only ensures the heating efficiency but also avoids thermal effects on the surrounding wire harnesses. Finally, it is connected to the spraying orifice 20 through a flexible hose, forming a pipeline system combining rigidity and flexibility, maintaining a stable connection in a vibrating environment.

[0049] According to the windshield washer fluid spraying system of the present disclosure embodiment, by configuring the heating section 40 in the delivery pipeline 30, efficient directional heating of the delivered windshield washer fluid can be achieved, rapidly raising the temperature of the windshield washer fluid to the optimal cleaning range, discharging and spraying the heated windshield washer fluid onto the windshield, significantly enhancing the dissolving and peeling capabilities for oil stains, glue stains, insect corpses, and thin ice layers, and effectively preventing the spraying orifice from freezing in a low-temperature environment, ensuring the stable operation of the cleaning function in extreme weather and providing a clear vision environment for the driver. Moreover, the heating section 40 adopts a rigid pipeline, which has stronger structural stability, guarantees the stable contact between the heating element and the windshield washer fluid, and provides a firm support for the heating element, ensuring uniform heat transfer and the stability of the heating efficiency.

[0050] As Figure 1 described, in the windshield washer fluid spraying system of the present disclosure embodiment, it further includes a water pump part 50. The water pump part 50 is arranged in the delivery pipeline 30 and is used to pump the windshield washer fluid from the liquid storage part 10 to the spraying orifice 20. The heating section 40 is arranged on the way between the water pump part 50 and the spraying orifice 20.

[0051] According to the glass water spraying system of the embodiments of the present disclosure, the heating section 40 is arranged between the water pump section 50 and the spraying port section 20. After the glass water is pressurized by the water pump section 50, it enters the heating section 40. The glass water under pressure helps to achieve rapid and uniform heat energy transfer. The rear arrangement of the heating section 40 avoids the continuous erosion of the pump body by high-temperature glass water, reduces the working temperature of the pump body, delays the aging process of the seals and impellers of the water pump section 50, and significantly extends the service life of the pump body. The heated glass water is sprayed out at high speed from the spraying port section under high-pressure drive. The synergistic effect of high temperature and high pressure makes the glass water atomize more fully and the water column more powerful, expanding the cleaning coverage area. At the same time, high temperature can enhance the activity of the glass water cleaner. Cooperating with the high-pressure impact force, it can effectively peel off stubborn stains, reduce the number of times the windshield wiper scrapes, and extend the service life of the windshield wiper.

[0052] See Figure 1 , in the glass water spraying system of the embodiments of the present disclosure, on the way between the water pump section 50 and the spraying port section 20, the heating section 40 is arranged at a position closer to the spraying port section 20 than the water pump section 50. That is to say, the heating section 40 is arranged close to the spraying port section 20.

[0053] According to the glass water spraying system of the embodiments of the present disclosure, the heating section 40 is arranged between the water pump section 50 and the spraying port section 20 and at a position closer to the spraying port section 20. For example, it can be arranged horizontally along the inner side of the vehicle front apron, close to the bottom of the windshield, shortening the transmission distance of the heated glass water to the spraying port section, so as to form an optimized layout of "short-range heating - immediate spraying". The shortened distance from the heating section 40 to the spraying port section 20 effectively reduces the conduction loss of heat in the pipeline, ensures that the glass water acts on the glass surface quickly after reaching the optimal cleaning temperature, greatly reduces the time for the glass water to maintain a high temperature state in the pipeline, and significantly improves the thermal utilization rate.

[0054] Above, with reference to Figure 1 The basic layout of the glass water spraying system of the embodiments of the present disclosure has been described. Next, with reference to Figure 2 The structure of the heating section 40 in the conveying pipeline 30 will be described.

[0055] Figure 2 Shows Figure 1 A schematic cross-sectional view of the structure of the heating section in the glass water spraying system shown in Figure 2 As shown, in the glass water spraying system of the embodiments of the present disclosure, the heating section 40 in the conveying pipeline 30 includes: a steel pipe part 41 as the innermost layer, which is in contact with the glass water; a heating part 42 arranged on the outer side of the steel pipe part 41; a heat insulation part 43 arranged on the outer side of the heating part 42; and an aluminum foil part 44 arranged on the outer side of the heat insulation part 43. The heating part 42 is, for example, a resistance wire, and the heat insulation part 43 is, for example, heat insulation cotton.

[0056] According to the heating section 40 of the windshield washer fluid spraying system of the present disclosure, through the collaborative action of the functional layers, the multi-layer structure of the heating section 40 can achieve efficient, safe and durable heating performance. The innermost steel pipe part 41 is made of a high thermal conductivity metal material and directly contacts the windshield washer fluid, ensuring rapid heat transfer to the windshield washer fluid. Moreover, the rigid characteristics of the steel pipe part 41 can provide a stable support for the heating section 40, resist the vibration and impact during vehicle operation, and avoid the risk of deformation or leakage caused by the softening of the flexible pipeline due to high temperature, significantly improving the system reliability. The heating part 42 is arranged outside the steel pipe part 41, and the heat acts directly on the windshield washer fluid through metal conduction. The circumferential heating ensures uniform temperature distribution of the windshield washer fluid, improves the heating response speed, and enables the windshield washer fluid to reach the optimal cleaning temperature in a short time. The heat insulation part 43 wraps the heating part 42, effectively blocking the outward dissipation of heat and preventing the heating part 42 from harming the outside, maintaining the internal temperature stability of the heating section 40, reducing energy loss, improving heating efficiency, ensuring that the windshield washer fluid remains at a high temperature during transportation, and at the same time reducing the overall energy consumption of the system. The outermost aluminum foil part 44 not only provides physical protection, but also can reflect external heat, further reducing heat loss, protecting the heat insulation part 43 from being scratched, and preventing the material of the heat insulation part 43 from causing harm to the human body. The multi-layer configuration of the heating section 40 of the present disclosure realizes efficient heating, reliable protection and energy-saving operation of the windshield washer fluid, and has excellent heating efficiency, durability and safety.

[0057] Since the heating part 42 uses a resistance wire, its cost is low and it can be tightly wound around the outside of the steel pipe part 41, evenly covering the cross-section of the windshield washer fluid flow, ensuring rapid heat conduction to the windshield washer fluid. Since the heat insulation part 43 uses heat insulation cotton, it can wrap the resistance wire and the steel pipe part 41, and use its low thermal conductivity characteristics to block the outward diffusion of heat, concentrate the heat energy towards the windshield washer fluid inside the steel pipe part 41, significantly improving the energy utilization rate. Moreover, the soft texture of the heat insulation cotton can absorb the mechanical stress caused by vehicle vibration on the resistance wire, prevent the resistance wire from breaking due to long-term vibration, and improve the system reliability.

[0058] As Figure 2 shown, in the heating section of this embodiment, the steel pipe part 41, the heating part 42, the heat insulation part 43 and the aluminum foil part 44 are arranged adjacent to each other in sequence. That is to say, the heating section 40 adopts a four-layer tightly-fitted integrated structure design, without setting redundant layers in the middle or redundant layers on the outermost side, and can achieve a more compact structure and cost reduction.

[0059] In the windshield washer fluid spraying system of the present disclosure Figure 1The part of the conveying pipeline 30 other than the heating section 40 is a hose section, and the hose section and the heating section can be connected into one body via an electronic quick connector. By dividing the conveying pipeline 30 into a rigid heating section 40 and a flexible hose section and achieving modular connection through an electronic quick connector, a rigid-flexible combined pipeline system is formed. The flexible hose section can be freely bent according to the vehicle structure and flexibly adapted to the complex engine compartment layout. The fixed installation of the rigid heating section ensures the stable operation of the heating part. The seamless connection of the two through the quick connector not only retains the high-efficiency heat conduction characteristics of the rigid section but also endows the overall system with flexible adaptation ability. Moreover, the electronic quick connector can also achieve tool-free disassembly and assembly, plug-and-play, simple assembly. When the heating section 40 needs to be maintained or replaced, it can be quickly separated and reset, significantly shortening the maintenance time. At the same time, it can also be electronically controlled to provide safety protection.

[0060] In addition, as Figure 1 shown, in the windshield washer fluid spraying system of the present disclosure embodiment, it further includes a BCM (Body Control Module) 60 as an example of the control part. The BCM 60 can receive the user's instructions and can also receive ambient temperature data. The user's instructions can be realized by the user inputting via the HMI. The ambient temperature data can be realized by the in-vehicle temperature sensor collecting the ambient temperature and sending the collected ambient temperature data to the BCM. In response to the received user's instructions, the BCM 60 controls the heating part 42 of the heating section 40 to perform one of turning on heating, turning off heating, and increasing or decreasing the heating current. The BCM 60 can also control the heating part to heat the windshield washer fluid to a predetermined temperature range and maintain it within the predetermined temperature range based on the received ambient temperature information.

[0061] Therefore, in this embodiment, by introducing the control part in the windshield washer fluid spraying system, precise and intelligent control of the cleaning process can be achieved, and personalized needs of users can be met through interaction with users. Regarding the control of increasing or decreasing the heating current, it can be realized by the user manually adjusting in the operation interface, or the BCM can collect the signals of the ambient temperature sensor and automatically control the heating current of the resistance wire to achieve spraying heated windshield washer fluid at 40°C to 50°C in different environments. The 40°C to 50°C mentioned here is only an example of the predetermined temperature range and is not restrictive. It can be other values.

[0062] In addition, in the windshield washer fluid spraying system according to the embodiments of the present disclosure, a monitoring unit (not shown in the figures) is further included. The monitoring unit monitors the open circuit of the electronic quick connector and sends the monitored open circuit signal to the body control module 60. Therefore, by using the monitoring unit, real-time monitoring and intelligent feedback of the open circuit state of the electronic quick connector can be achieved. The monitoring unit continuously monitors the electrical conductivity of the electronic quick connector. Once a circuit open caused by loosening, detachment, or poor contact of the connector is detected, a signal can be immediately sent to the body control module 60. This real-time feedback can ensure that the heating function and the start / stop of the water pump unit are always in a controllable state, avoiding heating interruption or windshield washer fluid leakage caused by physical connection failure, and improving reliability and safety.

[0063] The following briefly describes an application and control example of the windshield washer fluid spraying system according to the embodiments of the present disclosure in the case of being controlled by the BCM 60.

[0064] In a vehicle, the windshield washer fluid spraying system of this embodiment can be controlled by an interactive switch to flexibly trigger the function of heating windshield washer fluid. The windshield washer fluid spraying system can be independently selected by the user whether to activate the function of heating windshield washer fluid through the in-vehicle human-machine interface (HMI), such as the central control touch screen, the steering wheel shortcut keys, or voice commands. When the user checks the "Heat Windshield Washer Fluid" option on the HMI interface or issues a "Turn on Heating" command through voice, the signal is transmitted to the body control module (BCM) 60 via the in-vehicle CAN bus. As the central control hub, the BCM 60 immediately sends an activation signal to the windshield washer fluid system to trigger the heating section resistance wire to start working. Therefore, the user can flexibly switch modes according to actual needs, such as deicing in winter and removing tree gum in summer, which not only improves the cleaning efficiency in extreme scenarios but also avoids energy waste in normal temperature environments. In addition, for the heating temperature, the user can preset a predetermined temperature so that the windshield washer fluid can be stably heated to the predetermined temperature, and the temperature can also be adjusted by operating on the HMI.

[0065] In addition to the above-mentioned scenario where the user can autonomously turn on and off the heated glass water function through switch control, there can also be a scenario of automatic adaptive intelligent temperature adjustment. BCM60 integrates ambient temperature sensor data, collects engine compartment or external temperature in real time, forms dual input with HMI user instructions, and builds a closed-loop temperature control logic. For example, when the ambient temperature is low, such as below 0°C, BCM can automatically increase the heating current to ensure that the resistance wire runs at high power, and quickly heat the glass water to 40°C~50°C, or even above 50°C, so as to effectively dissolve the ice layer and prevent secondary freezing after injection; if the ambient temperature is relatively warm, such as between 10°C and 35°C, BCM dynamically reduces the heating power to maintain the water temperature at 40°C~50°C, taking into account the cleaning effect of oil film and mild glue stains, while reducing energy consumption. Through this dual adjustment mechanism of "user demand + environmental perception", the system can always stably control the temperature of the sprayed windshield washer fluid within the optimal active range of 40℃ to 50℃ within a wide temperature range of -30℃ to 40℃, ensuring that the detergent ingredients can fully exert their effects and significantly improving the cleaning efficiency under different climatic conditions.

[0066] Below, the scenario of full-link fault monitoring will be described. In the delivery pipeline 30 of the windshield washer spraying system of this embodiment, the rigid heating section 40 and the flexible hose section are connected through an electronic connector such as an electronic quick connector. The connector has a built-in detection circuit to monitor the connection status in real time. When the vibration or external force during vehicle driving causes the connector to loosen or fall off, the detection circuit recognizes that the line is open and immediately transmits the open fault signal to BCM60. BCM60 can accurately locate the fault point by analyzing the coding of abnormal signals, and alert the user through the flashing of the dashboard icon or the HMI pop-up window. At the same time, BCM60 can automatically cut off the power supply of the heating section to prevent the risk of short circuit due to poor contact and ensure system safety.

[0067] The windshield washer spraying system for a vehicle according to the embodiment of the present disclosure has been described in detail above, and it can at least achieve the following technical effects.

[0068] First of all, the glass water spraying system for vehicles of the disclosed embodiment can quickly melt ice and snow and efficiently restore a clear field of vision. When the windshield is covered with ice and snow, hot glass water at 40°C to 50°C can quickly increase the temperature of the ice layer through heat conduction, destroy the ice crystal structure and accelerate the melting process. Compared with traditional physical snow removal such as local removal with a snow scraper, hot glass water covers the entire glass surface in a uniform spraying manner, allowing the heat to penetrate the ice and snow layer directly to the glass base, which not only dissolves the surface snow, but also softens the interface between the ice layer and the glass, preventing residual ice from refreezing due to low temperature. This full-area heating cleaning method can eliminate large-area obstructions in a short time, significantly reducing the delay in vision recovery caused by manual de-icing, and is especially suitable for the rapid de-icing needs of vehicles in the early morning in cold areas.

[0069] Secondly, the glass water spraying system for vehicles of the disclosed embodiment can effectively remove oil stains and cope with pollution in complex road conditions. In winter or low temperature environments, the windshield of a vehicle is easily contaminated with mixed pollutants such as oily particles in the exhaust of the vehicle in front, road oil stains, and industrial dust while the vehicle is driving. By heating the hot glass water to a suitable cleaning temperature, such as above 40°C, the viscosity of the oil stains can be significantly reduced, and the ability of the glass water surfactant to wrap and disperse the oil molecules can be enhanced. High temperature intensifies the movement of oil film molecules and greatly increases the contact area with glass water, thereby accelerating the emulsification reaction and quickly decomposing the stubborn oil film into tiny particles that are easy to rinse. Compared with room temperature glass water, warm liquid can more thoroughly remove such viscous pollutants and avoid problems such as wiper beating and blurred vision caused by oil film residues.

[0070] In addition, the glass water spraying system for vehicles of the disclosed embodiment can achieve enhanced cleaning of stubborn stains and cope with extreme attachment scenarios. In the face of stubborn stains such as insect carcasses, gum, and bird droppings that are difficult to remove at low temperatures, hot glass water can enhance cleaning power through temperature empowerment. In the case of insect stains, the insect carcasses that hit the glass at high speed contain protein components, which are easy to dry and harden at low temperatures and adhere tightly to the glass surface. The high temperature (40°C to 50°C) of the hot glass water causes the protein to denature and coagulate, reducing viscosity, while softening the shellac, making it easier to peel off under the action of the wiper, avoiding repeated scraping and residual glue marks. In the case of gum and resin, in summer or when parked under the shade of trees, the sticky film formed after the gum drips on the glass will become brittle and hard at low temperatures. The hot glass water reduces the viscosity of the gum through heat energy conduction, weakens the intermolecular force, and cooperates with the chemical dissolution of the detergent in the glass water to quickly disintegrate the glue layer, avoiding the cumbersome process of traditional room temperature cleaning that requires multiple spraying or manual scraping.

[0071] Finally, the glass water spraying system for vehicles of the disclosed embodiment can also protect the wiper system and extend the life of components. In cold weather, ordinary glass water can easily harden the wiper rubber strip due to the low temperature after being sprayed, which increases the friction between the wiper rubber strip and the glass surface, not only causing abnormal wiping noise and residual water marks, but also accelerating the wear and aging of the edge of the rubber strip. In contrast, the continuous warming effect of hot glass water, such as a spraying temperature of 40°C to 50°C, can maintain the rubber strip in an appropriate rubber elastic range and reduce the hardening and brittle phenomenon caused by low temperature. The softened rubber strip can fit tightly to the curved surface of the glass, improve the smoothness of wiping, and reduce stress damage caused by excessive friction resistance, thereby extending the service life of the wiper. At the same time, the lubricating layer formed by the warm glass water on the glass surface can reduce the direct tearing of the rubber strip and stubborn stains, further reduce the risk of wear, and achieve dual optimization of cleaning effect and component protection.

Those skilled in the art should understand that various modifications, combinations, sub-combinations and substitutions can occur depending on design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
