Description
Technical Field
[0001] This application relates to the field of automotive cleaning technology, specifically to a device, method, and vehicle for removing insect residue from automotive windshields. Background Technology
[0002] When a vehicle is traveling at high speed, especially in summer or on roads with many insects, a large number of flying insects will collide with the windshield. Their body debris mixes with secretions and dries quickly, forming stubborn insect glue stains. These stains are mainly composed of proteins, fats, and polysaccharides, and have extremely strong adhesion and water resistance, making them difficult to remove effectively with regular windshield washer fluid and wipers.
[0003] In existing technologies, the removal of insect residue from windshields mainly relies on traditional windshield washer fluid. However, traditional windshield washer fluid formulas are designed for dust and mud, and their ability to dissolve dried insect residue is extremely limited, forcing users to repeatedly use the wipers to clean the windshield. This repeated wiping not only causes excessive consumption of windshield washer fluid but also easily creates fine scratches on the glass surface, affecting the driver's visibility. At the same time, it accelerates the aging and wear of the wiper blades, shortening their lifespan. Summary of the Invention

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.
[0020] To address the aforementioned issues, this application proposes a device, method, and vehicle for removing insect residue from automotive windshields, which can effectively remove stubborn insect residue stains from windshields, reduce the risk of glass scratches, and extend the service life of wiper blades.
[0021] Please refer to Figure 1 and Figure 2This application proposes a device for removing insect glue from a car windshield, including a heating module, a wiper assembly, a solvent supply spray module, and a controller. The heating module is used to heat the windshield; the wiper assembly includes a wiper arm and a wiper blade disposed on the wiper arm; the solvent supply spray module is used to spray insect glue solvent onto the windshield; and the controller is connected to the heating module, the wiper assembly, and the solvent supply spray module.
[0022] In the technical solution of this application, the mechanism of softening the insect glue by the heating module, dissolving the insect glue by the solvent supply spray module, and removing it in concert by the wiper assembly reduces the traditional repeated wiping operation, effectively removes stubborn insect glue stains on the windshield, reduces the risk of glass scratches, and extends the service life of the wiper blades.
[0023] The heating module is configured to heat the windshield. This heating module can be implemented in various ways. For example, it can use hot air, drawing hot air from the vehicle's air conditioning system or a separate heater and directing it to the windshield surface to raise the glass temperature. Another approach is to place a heat source at the front of the vehicle, transferring heat to the windshield via conduction or convection. Heating can also be achieved by integrating resistance wires or heating films inside or near the glass surface; these wires or films generate heat when energized, directly heating the glass.
[0024] The solvent supply spray module is configured to spray shellac solvent towards the windshield. This module may include a reservoir for storing the shellac solvent and a pump for drawing the solvent from the reservoir. The solvent can be delivered via piping to nozzles, which can be fixedly mounted at the front of the vehicle, such as under the hood or near the front bumper, and sprayed towards the windshield. The nozzles can be designed as single-hole or multi-hole nozzles to achieve spray coverage of varying ranges and shapes. The spray pressure and flow rate can be regulated via pump control to ensure that the solvent uniformly and effectively covers the target area.
[0025] The controller is connected to the heating module, the wiper assembly, and the solvent supply spray module via signal connections. This controller is the intelligent core of the entire device, responsible for coordinating the operation of each module. The controller can be a standalone microprocessor unit or integrated into the vehicle's existing electronic control unit. The controller establishes signal connections with each module via wired or wireless means, receives input signals from sensors (such as temperature sensors and rain sensors), and sends heating commands to the heating module, start or stop commands to the wiper assembly, and spray on or off commands to the solvent supply spray module according to preset programs or algorithms. The controller can intelligently adjust the heating intensity, spray duration, and wiper frequency according to actual needs to optimize the removal of insect residue.
[0026] In practical applications, if the solvent spraying position is fixed, the shellac solvent may not be able to accurately and evenly cover the shellac area on the windshield. Especially during the wiping process of the wiper assembly, the solvent may evaporate or be blown away by the wind before reaching the shellac area, thus affecting the shellac removal effect and wasting shellac solvent.
[0027] In this regard, this application further proposes a solvent supply spray module including a spray assembly, which is disposed on the wiper assembly and is used to follow the movement of the wiper assembly and spray shellac solvent onto the front windshield surface.
[0028] The spray assembly is a device used to spray shellac solvent onto the surface of the windshield in a specific manner (e.g., mist, fan, or stream). It may consist of one or more nozzles, an array of spray holes, or a flow guiding structure with micropores.
[0029] The spray assembly is mounted on the wiper assembly. This means there is a physical connection or integration between the spray assembly and the wiper assembly. This mounting method can be achieved through mechanical fastening (such as clips, screws), bonding, one-piece molding, or embedded design. For example, the spray assembly can be fixed to the wiper arm or integrated into the structure of the wiper blade. The purpose is to ensure that the spray assembly can move as a whole with the wiper assembly.
[0030] The spray assembly moves in tandem with the wiper assembly. Due to the physical connection between the spray assembly and the wiper assembly, when the controller drives the wiper assembly to perform a wiping action, the spray assembly moves synchronously along the surface of the windshield. This following-motion characteristic ensures that the solvent spray position can be dynamically adjusted, always remaining correlated with the current or upcoming position of the wiper assembly.
[0031] The solution proposed in this application integrates a spray assembly into the wiper assembly, enabling the solvent supply spray module to dynamically and precisely spray shellac solvent. Specifically, when the controller receives a cleaning start command, it first controls the heating module to preheat the windshield to soften the shellac. Subsequently, the controller activates the solvent supply spray module, spraying the shellac solvent onto the windshield surface through the spray assembly mounted on the wiper assembly. Because the spray assembly and wiper assembly move synchronously, the shellac solvent can be precisely sprayed onto the area that the wiper blade is about to wipe or is currently wiping. This close-range, synchronous spraying method ensures that the solvent maintains a high concentration and activity when acting on the shellac, effectively avoiding solvent loss due to wind or evaporation during spraying. After the solvent has fully acted on the shellac, the wiper assembly immediately begins wiping, removing the softened and dissolved shellac along with the solvent, thus achieving efficient and thorough shellac removal.
[0032] In a further embodiment, the spray assembly includes a guide channel disposed inside the wiper arm and a spray hole disposed on the wiper blade; the guide channel is connected to the liquid supply end of the solvent supply spray module, and the spray hole is connected to the guide channel.
[0033] The guide channel located inside the wiper arm refers to one or more channels formed within the wiper arm's structure for transporting fluid. This guide channel can be integrally formed during the wiper arm manufacturing process, such as by reserving a hollow structure during injection molding or extrusion molding; alternatively, it can be an independent flexible or rigid pipe embedded as a guide channel after the wiper arm is grooved inside. The main function of the guide channel is to provide an internal transport path for the shellac solvent from the supply end of the solvent supply spray module to the spray nozzles on the wiper blade, thereby avoiding the entanglement and exposure of external pipes and maintaining the integrity and aesthetics of the wiper assembly.
[0034] The nozzles on the wiper blades are tiny holes or nozzles on or inside the wiper blades used to spray shellac solvent. These nozzles can be evenly distributed along the length of the wiper blades or concentrated in specific areas as needed.
[0035] The guide channel is connected to the liquid supply end of the solvent supply spray module, which establishes a fluid connection between the inlet end of the guide channel and the main liquid supply pipeline of the solvent supply spray module. This connection can be achieved in various ways, such as using a corrosion-resistant flexible hose, or setting a rotary joint at the pivot of the wiper arm to accommodate the swing of the wiper arm, ensuring that the solvent can be continuously and stably supplied to the guide channel during the movement of the wiper arm.
[0036] The solution proposed in this application optimizes the structure of the spray assembly, making it highly integrated within the wiper assembly. Specifically, when the controller receives a cleaning start command, the solvent supply spray module begins operation, and the insect glue solvent is pumped out from its supply end. This solvent first enters a guide channel located inside the wiper arm. Because the guide channel is integrated into the wiper arm structure, the solvent delivery path is hidden and protected, avoiding visual interference, wear, or freezing risks that may arise from external piping. The solvent flows along the guide channel and is ultimately sprayed onto the windshield surface through nozzles on the wiper blade that communicate with the guide channel. Simultaneously with solvent spraying, the wiper assembly begins operation under the controller's drive, and the wiper blade scrapes the glass surface. This design allows the solvent to be precisely sprayed onto the area that the wiper blade is about to scrape or is currently scraping, ensuring full contact between the solvent and the insect glue, and working in conjunction with the mechanical scraping action of the wiper blade to efficiently remove the insect glue. Furthermore, by combining the preheating of the windshield with the heating module, the insect glue can be further softened, resulting in better penetration of subsequent solvents and better wiping performance of the wipers, thus forming an efficient, integrated and reliable insect glue removal system.
[0037] It is understandable that if shellac solvent is supplied to the same system as the vehicle's original windshield washer fluid, the shellac solvent may be diluted, thereby reducing its efficiency in removing shellac. At the same time, mixing solvents of different properties may also cause corrosion or contamination to the washer fluid system, affecting the long-term stable operation of the system.
[0038] In this regard, this application further proposes that the above-mentioned solvent supply spray module also includes an independent shellac solvent supply component, which is connected to the spray component.
[0039] The independent shellac solvent supply unit refers to a separate unit dedicated to storing and transporting shellac solvent, independent of the vehicle's existing windshield washer fluid supply system. This unit may include a separate reservoir, a separate pump, and corresponding piping. The reservoir is used to store the shellac solvent, and the pump draws the solvent from the reservoir and delivers it to the spray system. Alternatively, the unit can be a replaceable solvent cartridge or bag pre-filled with shellac solvent, connected to the pump or piping via a specific interface for plug-and-play operation. Furthermore, the independent shellac solvent supply unit may integrate a level sensor to monitor the remaining solvent level and feed the information back to the controller.
[0040] By employing an independent shellac solvent supply component, the purity and concentration of the shellac solvent can be ensured, avoiding dilution issues caused by mixing with conventional windshield washer fluid. This significantly improves the efficiency and effectiveness of shellac removal. Furthermore, the independent supply system prevents potential corrosion or contamination of the vehicle's existing washer fluid system by the shellac solvent, extending the lifespan of related components and reducing maintenance costs.
[0041] As can be seen from the above, there are various forms of heating modules. In a specific embodiment of this application, the heating module includes a flexible heating element for placement on the windshield; the flexible heating element at least covers the wiping area of the wiper blade on the windshield.
[0042] The heating module's function is to raise the temperature of the windshield to soften the insect residue adhering to it. This can be achieved, but is not limited to, heating via resistance wires, semiconductor materials, or infrared radiation. The flexible heating element is a heating component that can be bent and deformed to adapt to the curved shape of the windshield. It can be implemented using various technologies; for example, it can be a heating circuit printed with conductive ink on a transparent thin-film substrate, or a heating structure formed by embedding a fine mesh of metal wires within a flexible polymer layer.
[0043] The installation location of the flexible heating element refers to whether it is fixed or integrated into the windshield. This can be achieved by attaching the flexible heating element to the inner surface of the windshield or by integrating it as an intermediate layer into the sandwich structure of the windshield.
[0044] The wiping area refers to the area formed by the path of the wiper blade as it contacts and moves along the windshield during operation. The size and shape of the flexible heating element are designed to completely cover or extend beyond this area to ensure that the shellac in the wiper's cleaning path is effectively heated.
[0045] In the aforementioned automotive windshield insect residue removal device, the heating module is configured to include a flexible heating element. This flexible heating element is precisely positioned on the windshield, ensuring its coverage area at least encompasses the area where the wiper blades will be wiping the glass surface. When the controller issues a heating command, the heating module heats a specific area of the windshield via the flexible heating element. Because the flexible heating element can closely conform to the curved surface of the windshield and concentrate heat on the area about to be wiped by the wiper blades, it can efficiently and precisely soften the insect residue. This localized and targeted heating method allows the insect residue to reach an optimal softened state before being sprayed with solvent and wiped by the wipers, thereby significantly improving the removal efficiency and avoiding ineffective heating of uncleaned areas.
[0046] In one specific implementation, the flexible heating element can be a transparent conductive film. This film is laminated or adhered to the inner surface of the windshield, and its shape is pre-designed to match the wiping trajectory of the wiper blades, forming an arc-shaped or fan-shaped heating area. Electrodes are connected to both ends of the conductive film, and a voltage is applied to the film via the power supply of the heating module, thereby heating the glass in the covered area.
[0047] In some embodiments, this application proposes a device for removing insect residue from automotive windshields, which can remove insect residue from the windshield through the coordinated operation of a heating module, a solvent supply spray module, and a wiper assembly. However, in practical applications, if the device cannot accurately sense the adhesion of insect residue on the windshield and the current environmental parameters, it may lead to excessive solvent consumption, unnecessary heating operations, or poor cleaning results, thereby affecting the system's efficiency and user experience.
[0048] In this regard, this application further proposes that the automotive windshield insect glue removal device also includes a detection module, which is connected to the controller and is used to detect the insect glue adhesion on the windshield and environmental parameters.
[0049] The detection module can be implemented using image recognition technology. For example, a camera can be installed in front of or inside the vehicle to capture images of the windshield, and then image processing algorithms can be used to analyze the images to determine if there are insect glue spots, their size, density, and location. Alternatively, the detection module can be implemented using an optical sensor array. For instance, multiple infrared or laser sensors can be placed near the windshield to detect changes in the reflection, scattering, or absorption characteristics of light to determine if foreign objects are attached to the glass surface.
[0050] For environmental parameter detection, the detection module can integrate environmental sensors, such as a temperature sensor to measure ambient temperature, a humidity sensor to measure air humidity, and a light sensor to measure ambient light intensity. Alternatively, it can acquire data from the vehicle's existing sensor network, such as data from external temperature sensors and rain sensors already integrated into the vehicle's CAN bus, as input for environmental parameters. The detection module is connected to the controller to ensure that the acquired information is transmitted to the controller in real time and accurately, allowing the controller to make appropriate decisions and control commands based on this information.
[0051] By acquiring this information, the system can determine when to initiate cleaning, at what intensity, and whether heating is necessary. The detection module can perform detection periodically or proactively upon receiving a specific trigger signal. The detected data is preprocessed and sent to the controller in a standardized format. Alternatively, the detection module can continuously monitor and automatically send alarms or status updates to the controller when insect glue adhesion reaches a preset threshold or when environmental parameters change significantly.
[0052] Through the aforementioned technical solution, the automotive windshield insect residue removal device can sense the insect residue adhesion status and environmental parameters on the windshield in real time. Based on this real-time data, the controller can intelligently determine whether to initiate a cleaning operation and how to optimize the combination strategy of heating, spraying, and wipers. For example, when there is no insect residue or the amount of insect residue is minimal, the system can avoid unnecessary activation, thereby saving solvent and energy. When the ambient temperature is low, the system can activate heating as needed to ensure solvent activity and cleaning effectiveness. This on-demand, intelligent operating mode significantly improves the efficiency and effectiveness of insect residue removal, avoids resource waste, extends the service life of components in the device, and enhances the user experience.
[0053] Please refer to Figure 3 Based on the aforementioned car windshield insect residue removal device, this application also proposes a method for removing car windshield insect residue, which includes the following steps: S10: In response to the cleaning start command, control the heating module to heat the windshield; S20: Control the solvent supply spray module to turn on, so that the solvent is sprayed onto the glass surface, and control the operation of the wiper assembly at the same time.
[0054] The core of this embodiment lies in combining the heating module, solvent supply spray module, and wiper assembly in a dynamic and coordinated manner. This allows for simultaneous solvent spraying and mechanical scraping after the shellac has been heated and softened, solving the problem of the strong adhesion of dried shellac and its difficulty in removal. This achieves the effect of efficiently removing shellac while avoiding glass scratches and accelerated aging of wiper blades.
[0055] Specifically, this method is based on actual vehicle operating scenarios. When shellac stains are detected on the windshield, the controller receives a cleaning start command and activates the heating module to raise the surface temperature of the windshield to a suitable range. Since shellac stains are mainly composed of proteins, fats, and polysaccharides, their adhesion decreases significantly with increasing temperature. Therefore, the heating control effectively softens the physical structure of the dried stains. On this basis, the controller simultaneously coordinates the activation of the solvent supply spray module to precisely spray shellac solvent onto the glass surface. This solvent chemically decomposes the shellac components. Simultaneously, the wiper assembly starts operating, utilizing the reduced adhesion between the softened shellac and the glass to efficiently remove the stains through the wiping action of the wiper blades.
[0056] This application's solution couples the actions of heating, spraying, and wiping, avoiding the shortcomings of traditional technologies that rely solely on repeated wiping with conventional windshield washer fluid. For example, solvent spraying is performed immediately after heating and softening the shellac, significantly improving the solvent's penetration efficiency and shortening the dissolution time. The simultaneous operation of the wiper assembly ensures that the softened stains are removed in one pass, eliminating the need for repeated operations. This technical solution not only significantly reduces the amount of windshield washer fluid consumed during shellac removal but also fundamentally reduces the number of ineffective frictions between the wiper blades and the glass surface, effectively preventing glass scratches and extending the lifespan of the wiper blades.
[0057] As a specific implementation method, when a user discovers dried insect residue on the windshield after driving on roads with many insects in summer, a cleaning start command can be triggered. The controller then controls the heating module to operate, raising the glass surface temperature to the range of 40-55°C, softening the insect residue due to the heat effect; at the same time, the solvent supply spray module sprays a special insect residue solvent onto the glass, and the wiper assembly oscillates at a medium frequency.
[0058] In addition, users can activate the "shell glue cleaning mode" via the in-vehicle central control screen, steering wheel buttons, or voice commands, or the system can automatically trigger the cleaning process when the amount of shell glue attached reaches a preset threshold (such as a coverage area ≥ 5cm²) through the forward-facing camera.
[0059] In some embodiments described above, a cleaning method is proposed that responds to a cleaning start command, controls the heating module to heat the windshield, controls the solvent supply spray module to open so that the solvent is sprayed onto the glass surface, and simultaneously controls the operation of the wiper assembly. However, in some cases, such as when the ambient temperature is high or the insect residue is not severe, preheating the windshield may not be necessary, which may lead to unnecessary energy consumption and increase the waiting time of the cleaning process.
[0060] In this regard, this application further proposes steps prior to controlling the heating module to heat the windshield, including: Acquire information on ambient temperature and the state of insect glue adhesion; Based on the information regarding the ambient temperature and the adhesion status of the shellac, determine whether the heating conditions are met; If the heating conditions are met, then the heating operation is performed; If the heating conditions are not met, the heating operation is skipped, and the steps of controlling the solvent supply to the spray module and the wiper assembly are executed directly.
[0061] The acquisition of ambient temperature and insect glue adhesion information can be achieved in several ways. For example, ambient temperature information can be obtained using the vehicle's built-in ambient temperature sensor, or by connecting to the vehicle's CAN bus to obtain existing ambient temperature information from the vehicle's central control unit. Alternatively, a separate temperature sensor can be integrated externally for dedicated measurement of ambient temperature.
[0062] There are multiple ways to obtain information on the adhesion status of insect glue. For example, image recognition technology can be used to capture images of the windshield surface using a camera installed at the front of the vehicle, and the images can be analyzed to identify the distribution, density, and degree of adhesion of the insect glue. Alternatively, a detection module included in the aforementioned device can be used, which may contain optical sensors, ultrasonic sensors, etc., to directly detect the adhesion of foreign matter on the glass surface.
[0063] Based on the ambient temperature and the shellac adhesion status information, it is determined whether the heating conditions are met. This determination process is typically executed by a controller, which can preset a series of judgment rules or thresholds. For example, when the ambient temperature is lower than a certain preset temperature threshold (e.g., 15°C), or when the shellac adhesion status information shows that the shellac adhesion area or density exceeds a certain preset threshold, it is determined that the heating conditions are met. These thresholds and rules can be adjusted and optimized according to actual application needs to ensure that heating is performed when necessary while avoiding unnecessary heating.
[0064] If the heating conditions are met, the heating operation is executed. When the determination result indicates that the heating conditions are met, the controller sends a command to the heating module to start the heating module to heat the windshield. The specific method of heating operation may include controlling the power of the heating module, the heating time, etc., to ensure that the windshield reaches a suitable cleaning temperature.
[0065] If the heating conditions are not met, the heating operation is skipped, and the steps of controlling the solvent supply spray module and the wiper assembly are executed directly. When the determination result is that the heating conditions are not met, the controller will directly skip the start of the heating module and instead control the solvent supply spray module to start spraying shellac solvent onto the glass surface, while simultaneously controlling the wiper assembly to operate. This means that when heating is not required, the system can directly enter the solvent spraying and wiper cleaning stage, thereby saving time and energy.
[0066] Upon receiving a cleaning start command, the proposed solution does not immediately initiate heating. Instead, it first assesses the actual needs of the cleaning task by acquiring information on the ambient temperature and the state of insect residue adhesion. Based on this real-time information, the controller intelligently determines whether heating of the windshield is necessary using pre-defined logic. If heating is required, the controller activates the heating module to preheat the glass, softening stubborn insect residue and improving subsequent cleaning effectiveness. Conversely, if heating is not required, the system skips the heating step, immediately activating the solvent supply spray module to spray insect residue solvent and driving the wiper assembly to sweep. This decision-making mechanism based on actual conditions makes the entire insect residue removal process more intelligent and efficient. By introducing an intelligent judgment mechanism into the above cleaning method, this solution avoids unnecessary heating operations, thereby optimizing the cleaning process, improving energy efficiency, and shortening the overall cleaning time.
[0067] In one specific implementation, when a user issues a cleaning start command for removing insect residue from the windshield via the in-vehicle central control screen or voice command, the controller first obtains the current ambient temperature data from the vehicle's CAN bus, for example, if the current temperature is 15°C. Simultaneously, the controller activates the front-facing camera to capture images of the windshield and analyzes the images using a built-in image processing algorithm. It identifies a small amount of scattered insect residue adhering to the glass surface, but its density and area do not reach the preset "stubborn insect residue" level. Based on preset judgment rules (e.g., no heating is performed when the ambient temperature is above 10°C and the insect residue adhesion level is "light"), the controller determines that the current situation does not meet the heating conditions. Therefore, the controller skips the activation of the heating module and immediately controls the solvent supply spray module to start, spraying insect residue solvent onto the glass surface while simultaneously driving the wiper assembly to sweep, thus quickly completing the cleaning process.
[0068] In practical applications, shellac often only adheres to localized areas of the glass. If the entire scraping area is sprayed indiscriminately, it may lead to a waste of shellac solvent and reduce the removal effect on stubborn shellac due to excessive solvent dilution.
[0069] Please refer to Figure 4In a further embodiment of this application, step S20 includes: S21: Obtain the real-time motion trajectory of each spray hole on the wiper blade on the glass surface; S22: Compare the real-time movement trajectory of each nozzle with the area where the insect glue adheres; S23: When the real-time movement trajectory of any nozzle enters the preset spray trigger area corresponding to the shellac adhesion area, a spray start command is generated; S24: In response to the spray start command, control the solvent supply spray module to start.
[0070] The purpose of acquiring the real-time motion trajectory of each nozzle on the wiper blade on the glass surface is to accurately determine the current position of the solvent spray point. This can be achieved by installing an angle encoder or rotation sensor at the pivot of the wiper arm to monitor the swing angle of the wiper arm in real time. Combined with the geometry of the wiper arm and the relative position of the nozzle on the wiper blade, a preset geometric model can be used to calculate the real-time coordinates of each nozzle in the two-dimensional coordinate system of the windshield. Alternatively, visual sensors, such as cameras, can be installed inside or outside the vehicle to capture and process images of the nozzles on the wiper blade in real time, thereby identifying and tracking the motion trajectory of the nozzles on the glass surface.
[0071] The real-time movement trajectory of each nozzle is compared with the area where the insect glue adheres to determine whether the current position of the nozzle is related to the area where the insect glue needs to be cleaned. Specifically, the controller can pre-store or receive in real-time coordinate information or boundary data of the area where the insect glue adheres from the detection module. Subsequently, the real-time acquired nozzle movement trajectory data is used to perform geometric operations or logical judgments with these insect glue adherence area data to determine whether the nozzle is located in or about to enter the area where the insect glue adheres.
[0072] When the real-time movement trajectory of any nozzle enters the preset spray trigger zone corresponding to the shellac adhesion area, a spray start command is generated. The preset spray trigger zone is an extended area based on the shellac adhesion area, designed to initiate spraying before or immediately upon the nozzle reaches the shellac adhesion area, ensuring the solvent can effectively act on the shellac. This trigger zone can be defined as a buffer zone extending a certain distance outward from the shellac adhesion area, or dynamically adjusted based on factors such as the nozzle's spray range, solvent diffusion characteristics, and system response delay. When the real-time movement trajectory of the nozzle enters this preset zone, the controller generates an internal signal or electrical signal, namely the spray start command, to instruct the solvent supply spray module to prepare for or begin spraying. Responding to the spray start command and controlling the solvent supply spray module to start is crucial for executing the actual spraying action. Once the controller receives the spray start command, it immediately sends a control signal to the solvent supply spray module. The control signal can drive the micro-pump inside the solvent supply spray module to start, or open the solenoid valve connected to the spray nozzle, so that the shellac solvent can be accurately sprayed onto a specific area of the windshield through the spray nozzle on the wiper blade.
[0073] This application's solution precisely tracks the real-time movement trajectory of each nozzle on the wiper blade across the windshield surface. Combined with information about the area where insect glue adheres, obtained from a detection module, the controller compares the real-time position of the nozzle with the area requiring cleaning. When the controller determines that the real-time movement trajectory of any nozzle enters a preset spray trigger area corresponding to the area where insect glue adheres, it generates a spray activation command. This command is then sent to the solvent supply spray module, causing it to activate at a precise time, spraying insect glue solvent only onto or near the area where insect glue adheres. This mechanism ensures that the solvent spraying is not blindly covering the entire wiping area, but rather targeted at the location of the insect glue. In this way, the collaborative work between the solvent supply spray module and the wiper assembly is optimized, ensuring effective solvent utilization and improving the removal effect on stubborn, localized insect glue.
[0074] The following is a concrete example to illustrate this. A car windshield insect residue removal device operates as follows: First, the controller continuously monitors the swing angle of the wiper arm using an angle sensor mounted on the wiper arm pivot. Combining this with pre-stored data on the wiper arm length and the precise position of the nozzles on the wiper blade, it calculates the coordinates of each nozzle on the windshield in real time. Simultaneously, the vehicle's detection module (e.g., a wide-angle camera mounted behind the rearview mirror) uses image recognition algorithms to identify all areas on the windshield where insect residue adheres and sends the boundary coordinates of these areas to the controller. The controller compares the real-time coordinates of each nozzle with the boundary coordinates of these insect residue areas. For example, a preset spray trigger area can be set, which is a rectangular area extending 5 mm outward from the insect residue-attached area. When the controller detects that the real-time coordinates of a nozzle have entered the preset spray trigger area of any insect residue-attached area, it immediately generates a spray activation command. This command is then sent to the solvent supply spray module via the CAN bus. Upon receiving a command, the solvent supply spray module briefly opens a miniature solenoid valve connected to the corresponding spray nozzle, allowing shellac solvent to be precisely sprayed onto the target shellac area. Once the nozzle moves out of the trigger area, the solenoid valve closes, stopping the spraying.
