Description

Technical Field

[0001] This invention relates to the technical field of side window glass water deflectors, and more specifically, to a side window glass water deflector device, control method, and vehicle. Background Technology

[0002] In the existing technology, the removal of water fog and frost on the outside of automotive side windows mainly relies on air conditioning blowing, passive hydrophobic coatings, or mechanical scraping by fixed water deflectors when the glass is raised or lowered. There is a lack of active means to remove water fog and frost when the glass is stationary, and it is impossible to actively remove water fog or frost from the rearview mirror's field of vision area.

[0003] There is currently no effective solution to the technical problem that side window glass cannot actively clear water mist and frost from the rearview mirror's field of vision when stationary. Summary of the Invention

[0004] The main objective of this invention is to provide a side window glass water-blocking device, control method, and vehicle to solve the technical problem in the prior art that side window glass cannot actively clear water mist and frost from the rearview mirror's field of vision when stationary.

[0005] To achieve the above objectives, according to one aspect of the present invention, a side window glass water-blocking device is provided, comprising: a water-blocking module, the water-blocking module including at least a first outer water-blocking strip and a second outer water-blocking strip, the first outer water-blocking strip being fixedly connected to a vehicle door, the second outer water-blocking strip being rotatably connected to a vehicle door, the second outer water-blocking strip being disposed near a rearview mirror, the second outer water-blocking strip having a first position abutting against the first outer water-blocking strip along the length direction of the vehicle door, and a second position offset from the first outer water-blocking strip along the height direction of the vehicle door; a drive module, the drive shaft of the drive module being connected to the second outer water-blocking strip, the drive module being used to drive the second outer water-blocking strip to switch between the first position and the second position, so that the second lip of the second outer water-blocking strip scrapes the outer surface of the side window glass.

[0006] Furthermore, the side window glass water-blocking device also includes a heating component, which includes a heating wire disposed inside the second outer water-blocking strip. The heating wire extends along the length of the second outer water-blocking strip, and is disposed near the second lip of the second outer water-blocking strip.

[0007] Furthermore, the second lip includes a lip colloid and a supporting skeleton, with the lip colloid covering the outside of the supporting skeleton.

[0008] Furthermore, the first outer water-retaining strip is provided with a first lip, and the mating surface between the first lip and the second lip is an inclined surface or an arc-shaped surface.

[0009] Furthermore, the side window glass water deflector also includes a control module, which is electrically connected to the drive module. The control module is used to control the drive module to drive the second outer water deflector to rotate relative to the door, and to adjust the rotation angle of the second outer water deflector to adapt to different vehicle models.

[0010] Furthermore, the side window glass water-blocking device also includes: a speed sensor, which is electrically connected to the control module. The speed sensor is used to detect the speed of the drive shaft of the drive module and feed the speed back to the control module. The control module controls the drive state of the drive module according to the speed.

[0011] According to another aspect of the present invention, a control method for a side window glass water-blocking device is provided. The side window glass water-blocking device is the aforementioned side window glass water-blocking device. The control method includes: receiving a control command for a target object, wherein the control command includes at least: a rotation mode command, a rotation heating mode command, and a closing mode command; responding to the control command and generating a control strategy set, the control strategy set being used to control a target component to perform a target action, wherein the control strategy set includes: controlling a drive module to drive a second outer water-blocking strip to rotate forward and backward at a preset frequency, controlling the heating circuit connected to the heating wire, controlling the heating circuit cut off by the heating wire, and controlling the drive current of the drive module to be cut off.

[0012] Furthermore, the control method also includes: acquiring the rotational speed of the drive shaft of the drive module; when executing a rotation mode command, if the rotational speed of the drive shaft is less than a preset speed or the rotational speed of the drive shaft is equal to zero, controlling the cut-off of the drive current of the drive module.

[0013] Furthermore, the control method also includes: acquiring the temperature of the heating wire; and when the temperature of the heating wire is greater than or less than the preset temperature during the execution of the rotary heating mode command, controlling and adjusting the heating power of the heating wire.

[0014] According to another aspect of the present invention, a vehicle is provided, the vehicle including the aforementioned side window glass water deflector.

[0015] Applying the technical solution of this invention, the second outer water deflector is rotatably connected to the car door. When the drive module is not in operation, the second outer water deflector remains in the first position, and the second outer water deflector aligns with the first outer water deflector along the length of the car door, providing a water-blocking and sealing function, and can also scrape the outer surface of the side window glass during the lifting and lowering process. When the drive module is in operation, it drives the second outer water deflector to switch between the first and second positions, thereby causing the second lip of the second outer water deflector to scrape the outer surface of the side window glass. The second outer water deflector is positioned close to the rearview mirror, meaning the second lip actively scrapes the rearview mirror's field of vision area of ​​the side window glass to quickly remove water mist and frost from the rearview mirror's field of vision area, ensuring that the driver can clearly see the rearview mirror through the side window glass and drive safely. In the above solution, the second lip of the second outer water deflector can actively scrape the rearview mirror's field of vision area of ​​the side window glass, solving the technical problem in the prior art that the side window glass cannot actively remove water mist and frost from the rearview mirror's field of vision area when stationary.

[0038] In the existing technology, the removal of water fog and frost on the outside of automotive side windows mainly relies on air conditioning blowing, passive hydrophobic coatings, or mechanical scraping by fixed water deflectors when the glass is raised or lowered. The removal speed is slow and the effect is not good. There is a lack of active means to remove water fog and frost in a stationary state. It is impossible to actively remove water fog or frost in the rearview mirror field of vision area, thus affecting the visibility of drivers and passengers.

[0039] While there are existing technologies that use electric heating to defog, these are mostly applied to the windshield or rear window, and are not currently used on side windows.

[0040] To address the aforementioned issues, this application provides the following solutions.

[0041] Combination Figures 1 to 3 As shown in the figure, according to a specific embodiment of this application, a side window glass water-blocking device is provided.

[0042] Specifically, the side window glass water-blocking device includes a water-blocking module and a drive module. The water-blocking module includes at least a first outer water-blocking strip 2 and a second outer water-blocking strip 3. The first outer water-blocking strip 2 is fixedly connected to the door 1, and the second outer water-blocking strip 3 is rotatably connected to the door 1. The second outer water-blocking strip 3 is positioned near the rearview mirror. The second outer water-blocking strip 3 has a first position that aligns with the first outer water-blocking strip 2 along the length direction of the door 1, and a second position that deviates from the first outer water-blocking strip 2 along the height direction of the door 1. The drive shaft of the drive module is connected to the second outer water-blocking strip 3. The drive module is used to drive the second outer water-blocking strip 3 to switch between the first position and the second position, so that the second lip 31 of the second outer water-blocking strip 3 scrapes the outer surface of the side window glass 5.

[0043] In the embodiments of this application, the second outer water deflector 3 is rotatably connected to the door 1. When the drive module is not in operation, the second outer water deflector 3 remains in the first position, and the second outer water deflector 3 connects with the first outer water deflector 2 along the length of the door 1, serving as a water-blocking and sealing function, and can scrape the outer surface of the side window glass 5 during the lifting and lowering process. When the drive module is in operation, it drives the second outer water deflector 3 to switch between the first and second positions, thereby causing the second lip 31 of the second outer water deflector 3 to scrape the outer surface of the side window glass 5. The second outer water deflector 3 is positioned close to the rearview mirror, that is, the second lip 31 actively scrapes the rearview mirror's field of vision area of ​​the side window glass 5 to quickly remove water mist and frost from the rearview mirror's field of vision area, ensuring that the driver can clearly see the rearview mirror through the side window glass 5 and drive safely. In the above solution, the second lip 31 of the second outer water deflector 3 can actively scrape the rearview mirror's field of vision area of ​​the side window glass 5, solving the technical problem in the prior art that the side window glass 5 cannot actively remove water mist and frost from the rearview mirror's field of vision area when stationary.

[0044] It should be noted that the area of ​​the side window glass 5 near the rearview mirror is the rearview mirror field of view area of ​​the side window glass 5, and the driver observes the rearview mirror through the rearview mirror field of view area.

[0045] Understandably, an outer and inner water deflector strip are installed on the frame of door 1, forming a mounting groove between them. The side window glass 5 is located within this groove, with its outer surface abutting against the lip of the outer water deflector strip and its inner surface abutting against the lip of the inner water deflector strip. During the raising and lowering of the side window glass 5, the lip of the outer water deflector strip scrapes against the outer surface of the side window glass 5 to remove water mist and frost. When the side window glass 5 is stationary, the lip of the outer water deflector strip acts as a seal and guides water, preventing water from flowing down the side window and directing it outside the vehicle.

[0046] The first outer water-blocking strip 2 and the second outer water-blocking strip 3 can be made of EPDM (ethylene propylene diene monomer rubber) or TPV (thermoplastic elastomer) material.

[0047] Furthermore, the side window glass water-blocking device also includes a heating component, which includes a heating wire 4. The heating wire 4 is disposed inside the second outer water-blocking strip 3 and extends along the length direction of the second outer water-blocking strip 3. The heating wire 4 is disposed near the second lip 31 of the second outer water-blocking strip 3.

[0048] In the embodiments of this application, under conditions of severe low-temperature frost or condensation, it is difficult to completely remove frost or water film by relying solely on the rotating scraping of the second outer water baffle 3. The heating wire 4, which is located near the second lip 31, can transfer heat to the side window glass 5 through the second lip 31, thereby softening the frost and evaporating the water film, greatly reducing the adhesion between the glass surface and the second lip 31. This can efficiently remove water stains or ice crystals that have been weakened by heat, improve the cleaning efficiency, and avoid incomplete scraping or overload of the mechanism caused by hard foreign objects.

[0049] like Figure 1 As shown, the first outer water deflector 2 and the second outer water deflector 3 are both fitted onto the outer sheet metal 12 of the door 1. The side of the first outer water deflector 2 and the second outer water deflector 3 closest to the outer trim panel 11 of the door 1 is provided with a third lip 32. The first outer water deflector 2 and the second outer water deflector 3 abut against the outer trim panel 11 of the door 1 through the third lip 32. The side of the first outer water deflector 2 and the second outer water deflector 3 closest to the outer sheet metal 12 of the door 1 is provided with a fourth lip 33. The first outer water deflector 2 and the second outer water deflector 3 abut against the outer sheet metal 12 of the door 1 through the fourth lip 33. The first outer water deflector 2 and the second outer water deflector 3 are both provided with a slot 34. Part of the outer trim panel 11 of the door 1 is inserted into the slot 34. That is, the first outer water deflector 2 and the second outer water deflector 3 are connected to the door 1 through the third lip 32, the fourth lip 33 and the slot 34.

[0050] like Figure 1 As shown, the top of the outer sheet metal 12 of the door 1 is provided with a flange, which abuts against the top surface of the first outer water deflector 2 to achieve a stable connection with the first outer water deflector 2. A portion of the flange at the top of the outer sheet metal 12 is provided with a clearance opening (not shown in the figure), which is opposite to the second outer water deflector 3, so that the second outer water deflector 3 can move along the height direction of the door 1 from the clearance opening.

[0051] The second outer water deflector 3 is rotatably connected to the outer sheet metal 12 of the door 1 via a pivot (not shown in the figure). The axis of the pivot extends along the thickness direction of the door 1, allowing the second outer water deflector 3 to rotate around the pivot. During the rotation of the second outer water deflector 3, the second lip 31 of the second outer water deflector 3 scrapes against the outer surface of the side window glass 5. The scraping area of ​​the second lip 31 is a fan-shaped area, which is the rearview mirror's field of vision area, allowing the driver to clearly observe the rearview mirror through this fan-shaped area.

[0052] like Figure 1 As shown, the second outer water deflector 3 has a mounting hole located near the root of the second lip 31. This mounting hole extends along the length of the second outer water deflector 3. A heating wire 4 passes through this mounting hole, and its two ends are connected to the vehicle's low-voltage power supply via wires to form a heating circuit. A control switch is provided on this heating circuit; by controlling the opening and closing of the switch, the heating circuit is opened and closed. The heating wire 4 is made of flexible metal wire such as nickel-chromium alloy wire.

[0053] The metal frame of the heating wire 4 and the second outer water baffle 3 needs to be effectively isolated.

[0054] The second outer water baffle 3 is designed with stress relief structures at both ends to absorb or disperse mechanical tensile and bending stresses caused by the rotation, vibration, thermal expansion and contraction of the second water baffle. The stress relief structure can be a groove formed at the end of the second outer water baffle 3, and the wire is bent and accommodated in the groove to avoid damage to the wire due to stretching and vibration.

[0055] The conductor has sealing sleeves at both ends. These sleeves fill the gap between the conductor and the second water-blocking strip, preventing external media such as water vapor, dust, and salt spray from penetrating inward along the conductor path.

[0056] Furthermore, the second lip edge 31 includes a lip edge adhesive and a support skeleton 311, with the lip edge adhesive covering the outside of the support skeleton 311.

[0057] In the embodiments of this application, a support frame 311 is embedded in the second lip 31 to enhance the rigidity of the second lip 31, so that the second lip 31 moves as a whole during rotation, rather than being twisted locally.

[0058] like Figure 1 As shown, the second lip 31 includes a lip colloid and a support skeleton 311. The shape of the support skeleton 311 is adapted to the shape of the second lip 31, and the lip colloid covers the outside of the support skeleton 311. The support skeleton 311 can be made of metal (such as stainless steel) or high-strength engineering plastic (such as glass fiber reinforced polyamide material).

[0059] The drive module is a Hall motor (not shown in the figure). The drive module is connected to the inner panel of the door 1. The drive shaft of the drive module is connected to the second water baffle. The axis of the drive shaft extends along the thickness direction of the door 1.

[0060] Furthermore, the first outer water-blocking strip 2 is provided with a first lip 21, and the mating surface 6 between the first lip 21 and the second lip 31 is an inclined surface or an arc-shaped surface.

[0061] In the embodiments of this application, the mating surface 6 of the first lip 21 and the second lip 31 is an inclined surface or an arc-shaped surface, which can play a guiding role, guiding the second lip 31 to insert inward to mate with the edge of the first lip 21. When water stains on the side window glass 5 seep inward under the action of gravity, the mating surface 6 of the first lip 21 and the second lip 31 is an inclined surface or an arc-shaped surface, and the mating surface 6 is set at a certain angle with the vertical direction, so it can effectively prevent water stains from seeping inward along the mating surface 6.

[0062] For example, such as Figure 2 As shown, the first lip 21 is continuously arranged along the length direction of the first outer water baffle 2, and the second lip 31 is continuously arranged along the length direction of the second outer water baffle 3. The side of the first lip 21 closest to the second lip 31 is the first inclined surface, and the side of the second lip 31 closest to the first lip 21 is the second inclined surface. When the second outer water baffle 3 is in the first position, the second lip 31 is tightly fitted with the first lip 21.

[0063] For example, such as Figure 3 As shown, the first lip 21 is continuously arranged along the length direction of the first outer water baffle 2, and the second lip 31 is continuously arranged along the length direction of the second outer water baffle 3. The side of the first lip 21 closest to the second lip 31 is concave, and the side of the second lip 31 closest to the first lip 21 is convex. When the second outer water baffle 3 is in the first position, the second lip 31 is tightly fitted with the first lip 21.

[0064] Furthermore, the side window glass water deflector also includes: a control module, which is electrically connected to the drive module. The control module is used to control the drive module to drive the second outer water deflector 3 to rotate relative to the door 1, and to adjust the rotation angle of the second outer water deflector 3 to adapt to different vehicle models.

[0065] In the embodiments of this application, the curvature of the side window glass 5 of different models is different, which leads to different viewing areas of the side window glass 5. The rotation angle, swing frequency and starting position of the drive module can be adjusted by the control module. Without changing the mechanical structure of the side window glass water blocking device, it can be adapted to different models and improve the versatility of the side window glass water blocking device.

[0066] For example, the control module is an automotive-grade microcontroller (MCU), which can be integrated into the body control module (BCM) or arranged separately.

[0067] Furthermore, the side window glass water-blocking device also includes: a speed sensor, which is electrically connected to the control module. The speed sensor is used to detect the speed of the drive shaft of the drive module and feed the speed back to the control module. The control module controls the drive state of the drive module according to the speed.

[0068] In the embodiments of this application, the speed sensor monitors the speed of the drive shaft in real time to determine whether the drive module is operating normally, and can cut off the drive current of the drive module in time to avoid the drive module burning out due to overload.

[0069] For example, the drive module is a Hall motor, and the speed sensor is a Hall sensor integrated on the Hall motor. The Hall sensor monitors the speed of the drive shaft in real time and feeds back the speed of the drive shaft to the control module. When the speed of the drive shaft drops abnormally or suddenly stops rotating (stalled), the control module will cut off the drive current of the drive module.

[0070] Preferably, when the speed of the drive shaft drops abnormally or suddenly stops rotating (stalled), the control module controls the alarm to issue an alarm prompt to alert the driver that the drive module has malfunctioned.

[0071] Furthermore, when the speed of the drive shaft drops abnormally or suddenly stops rotating (stalled), the control module can control the drive module to perform reverse drive for a short period of time.

[0072] According to another specific embodiment of this application, a control method for a side window glass water-blocking device is provided, wherein the side window glass water-blocking device is the same as the side window glass water-blocking device described in the above embodiment, such as... Figure 4 As shown, the control method includes the following steps:

[0073] Step S1: Receive control commands from the target object, wherein the control commands include at least: rotation mode command, rotation heating mode command, and off mode command.

[0074] For example, the driver can select to turn the rotation function and the rotation heating function on or off via the operation buttons on the center console, the touch screen interface, or the shortcut keys on the steering wheel, that is, input rotation mode command, rotation heating mode command, and off mode command to the control module.

[0075] Step S2: Respond to the control command and generate a control strategy set. The control strategy set is used to control the target component to perform the target action. The control strategy set includes: controlling the drive module to drive the second outer water baffle 3 to rotate forward and backward at a preset frequency, controlling the heating circuit of the heating wire 4 to be connected, controlling the heating circuit of the heating wire 4 to be cut off, and controlling the drive current of the drive module to be cut off.

[0076] In the embodiments of this application, the second lip 31 actively scrapes the rearview mirror viewing area of ​​the side window glass 5 to quickly remove water mist and frost from the rearview mirror viewing area, ensuring that the driver can clearly see the rearview mirror through the side window glass 5 and drive safely. The second outer water deflector 3 is equipped with a heating wire 4, which heats the area scraped by the second lip 31 (rearview mirror viewing area) to effectively melt frost and evaporate water mist, reducing the scraping resistance of the second lip 31 and improving its scraping efficiency. In the above solution, the second lip 31 of the second outer water deflector 3 can actively scrape the rearview mirror viewing area of ​​the side window glass 5, solving the technical problem in the prior art that the side window glass 5 cannot actively remove water mist and frost from the rearview mirror viewing area when stationary.

[0077] For example, the side window glass water-blocking device includes: a water-blocking module, a drive module, a control module, and a heating circuit for a heating wire. The water-blocking module includes a first outer water-blocking strip 2 and a second outer water-blocking strip 3. The first outer water-blocking strip 2 is fixedly connected to the vehicle door 1, and the second outer water-blocking strip 3 is rotatably connected to the vehicle door 1. The second outer water-blocking strip 3 is positioned near the rearview mirror. The second outer water-blocking strip 3 has a first position that aligns with the first outer water-blocking strip 2 along the length direction of the vehicle door 1, and a second position that deviates from the first outer water-blocking strip 2 along the height direction of the vehicle door 1. The drive module uses a Hall motor, which integrates a Hall sensor. The drive shaft of the Hall motor is connected to the second outer water-blocking strip 3. The Hall motor is used to drive the second outer water-blocking strip 3 to switch between the first position and the second position, so that the second lip 31 of the second outer water-blocking strip 3 scrapes the outer surface of the side window glass 5. Heating wire 4 is located inside the second outer water baffle 3 and extends along the length of the second outer water baffle 3. The heating wire 4 is located near the second lip 31 of the second outer water baffle 3. A temperature sensor is provided inside the second outer water baffle 3 to monitor the temperature of the heating wire 4 in real time.

[0078] For example, when the control module does not receive any activation signal, the control module does not supply power to the drive module (Hall motor) and heating wire 4, and the second outer water deflector 3 remains in the first position, with the second outer water deflector 3 interfacing with the first outer water deflector 2 along the length of the door 1. In this mode, the second outer water deflector 3 performs only its conventional functions: the second outer water deflector 3 fills the gap between the side window glass 5 and the door 1 frame to prevent wind, rain, and dust from entering the interior of the door 1 and the passenger compartment; the second outer water deflector 3 guides rainwater flowing down the side window glass 5 to a specific drainage path; when the window glass rises or falls, the second outer water deflector 3 scrapes away the water film on the outer surface of the glass, maintaining the clarity of a portion of the side window glass 5.

[0079] For example, in rainy or foggy weather, relying solely on the air conditioning to clear water mist from the side windows is slow and may affect safe driving. In such cases, the rotation mode needs to be activated. When the control module receives the rotation mode command, it outputs a preset PWM (Pulse Width Modulation) drive signal to the drive module (Hall motor), which rotates in a preset direction and speed. In this mode, the second outer water deflector 3 rotates in both directions. For example, the second lip 31 of the second outer water deflector 3 rotates 60° clockwise, pauses for 0.5 seconds, and then rotates 60° counterclockwise back to its original position, forming a fan-shaped scraping area. This scraping area is within the rearview mirror's field of vision. The rotating second lip 31 mechanically scrapes away water mist or small water droplets in the rearview mirror's field of vision, pushing them away from the field of vision. Once the driver's field of vision is clear, the function can be manually turned off, or it can be set by the control module to turn off at a set time (e.g., automatically stopping after 2 minutes of continuous operation), or it can be automatically turned off after the integrated visual sensor determines the degree of cleanliness.

[0080] For example, in cold weather, the side window glass 5 is prone to frost or thick condensation, and mechanical scraping alone is not very effective. In this case, the rotary heating mode needs to be activated. When the control module receives the rotary heating mode command, it simultaneously activates the drive motor of the drive module (Hall motor) and the heating circuit of the heating wire 4. The control module outputs a constant power or a PWM (Pulse Width Modulation) controlled current to the heating wire 4, causing it to heat up and stabilize its temperature at 55℃~65℃. This temperature effectively melts frost and evaporates water vapor, and is below the aging temperature of the second outer water deflector 3 and the heat resistance temperature of the glass. In this mode, the second outer water deflector 3 rotates in both directions, while the heating wire 4 heats the area (rearview mirror field of view) scraped by the second lip 31 of the second outer water deflector 3 to effectively remove water vapor and frost from the area. Once the driver's field of vision is clear, the function can be manually turned off, or it can be set by the control module to turn off at a timer (e.g., automatically stopping after 2 minutes of continuous operation), or it can be automatically turned off after the integrated visual sensor determines the degree of cleanliness.

[0081] For example, when the side window water deflector is running in the rotating heating mode, the control module receives a shutdown mode command. The drive module first slowly rotates the second outer water deflector back to the initial docking position (first position) at a low speed to ensure that the second lip is completely in contact with the first lip of the first outer water deflector, restoring the sealing state. Subsequently, the heating wire power is delayed and turned off, so that the second water deflector retains residual heat for 3-5 seconds after the power is cut off, which helps to evaporate the residual water film and prevents water droplets from freezing again and adhering to the surface of the second lip at low temperature. Finally, the system enters a low-power standby state, retaining only the power supply to the Hall sensor and temperature sensor to continuously monitor abnormal states (such as doors not closed, water deflectors not returning to their original positions, etc.) and automatically recording fault logs for later diagnosis.

[0082] Furthermore, the control method also includes the following control steps:

[0083] Step S211: Obtain the rotational speed of the drive shaft of the drive module.

[0084] Specifically, the drive module is a Hall motor, which integrates a Hall sensor. When the drive module is working, the Hall sensor monitors the rotational speed of the Hall motor drive shaft in real time. The Hall sensor is electrically connected to the control module, and transmits the collected rotational speed signal to the control module.

[0085] Step S212: When executing the rotation mode command, if the speed of the drive shaft is less than the preset speed or the speed of the drive shaft is equal to zero, the drive current of the drive module is cut off.

[0086] It should be noted that if the speed of the drive shaft is less than the preset speed or the speed of the drive shaft is zero, there are two possible situations: the second lip 31 encounters an obstacle, causing the second lip 31 to be unable to rotate, and the obstacle needs to be removed in time, or the drive current of the Hall motor needs to be cut off; the Hall motor itself is malfunctioning, and the machine needs to be stopped and repaired in time.

[0087] In the embodiments of this application, the control module determines in real time whether the drive module is operating normally based on the drive shaft speed of the drive module, and can cut off the drive current of the drive module in time when the drive module malfunctions, so as to prevent the drive module from burning out due to overload.

[0088] Furthermore, when the drive module malfunctions, the control module controls the alarm to issue an alarm prompt, so as to remind the driver to check the operating status of the drive module and the second lip 31 in a timely manner.

[0089] For example, in rotation mode or rotation heating mode, if the Hall sensor detects a sudden drop in the speed of the Hall motor or a complete stop (such as when it encounters ice or foreign objects blocking it), the control module will immediately perform multiple protective actions: First, it will cut off the power supply to the heating wire to prevent local overheating caused by the stalled motor; second, the drive module will attempt to perform 1 to 3 short-term reverse micro-movements (such as reversing 5° and pausing for 0.3s) to loosen the obstruction. If the motor still fails to recover after three attempts, it will be determined to be a serious stall, and the system will lock the function and illuminate the fault indicator light. At the same time, it will send a warning message to the owner through the vehicle networking module: "The side window water deflector is blocked. Please check the glass surface." This enables remote interactive fault management.

[0090] Furthermore, the control method also includes the following control steps:

[0091] Step S221: Obtain the temperature of heating wire 4.

[0092] Specifically, a temperature sensor is installed inside the second water baffle. The temperature sensor is electrically connected to the control module, and the sensing end of the temperature sensor is connected to the heating wire 4 to collect the temperature of the heating wire 4. The preset temperature of the heating wire 4 is 55℃~65℃. This temperature can effectively melt frost and evaporate water mist, and is lower than the aging temperature of the second outer water baffle 3 and the heat resistance temperature of the glass.

[0093] Step S222: When executing the rotary heating mode command, if the temperature of the heating wire 4 is greater than or less than the preset temperature, control and adjust the heating power of the heating wire 4.

[0094] It should be noted that if the temperature of the heating wire 4 is higher than the preset temperature, it will accelerate the aging of the second outer water deflector 3 and damage the side window glass 5, requiring a lower heating power of the heating wire 4; if the temperature of the heating wire 4 is lower than the preset temperature, it will not be able to effectively remove the frost and water mist on the side window glass 5, requiring an increase in the heating power of the heating wire 4.

[0095] In the embodiments of this application, the control module determines in real time whether the temperature of the heating wire 4 is within the preset range based on the temperature of the heating wire 4. When the temperature of the heating wire 4 is not within the preset range, the heating power of the heating wire 4 is adjusted in a timely manner to ensure the efficiency of removing frost and water mist.

[0096] For example, in rotary heating mode, the control strategy set not only activates the drive module and heating wire, but also initiates a temperature closed-loop control algorithm. The power of the heating wire is not a constant output, but is dynamically adjusted by the control module based on a PID (proportional-integral-derivative) control strategy. The control module continuously receives feedback signals from the temperature sensor embedded in the second outer baffle. If the temperature of the contact area is detected to be below 55°C, the PWM duty cycle is increased to enhance the heating power; if the temperature exceeds 65°C, the output is immediately reduced to prevent the second outer baffle from cracking or the glass from developing thermal stress cracks due to localized overheating. Simultaneously, the system records the heating duration and cumulative number of runs. If continuous operation for more than 3 minutes fails to detect significant dissipation of water vapor (which can be indirectly determined through visual sensors or impedance changes), an auxiliary prompt is triggered: a flashing icon on the instrument panel or a voice prompt stating "Please check the dirt on the glass surface" guides the driver to manually clean the glass, preventing the system from operating under high load for extended periods.

[0097] According to another specific embodiment of this application, a vehicle is provided, the vehicle including the side window glass water deflector in the above embodiment.

[0098] Specifically, the side window glass water-blocking device includes a water-blocking module and a drive module. The water-blocking module includes a first outer water-blocking strip 2 and a second outer water-blocking strip 3. The first outer water-blocking strip 2 is fixedly connected to the door 1, and the second outer water-blocking strip 3 is rotatably connected to the door 1. The second outer water-blocking strip 3 is positioned near the rearview mirror. The second outer water-blocking strip 3 has a first position that aligns with the first outer water-blocking strip 2 along the length direction of the door 1, and a second position that deviates from the first outer water-blocking strip 2 along the height direction of the door 1. The drive shaft of the drive module is connected to the second outer water-blocking strip 3. The drive module is used to drive the second outer water-blocking strip 3 to switch between the first position and the second position, so that the second lip 31 of the second outer water-blocking strip 3 scrapes the outer surface of the side window glass 5.

[0099] When the drive module is not in operation, the second outer water deflector 3 remains in the first position. The second outer water deflector 3 connects with the first outer water deflector 2 along the length of the door 1, providing a water-blocking and sealing function, and also scraping the outer surface of the side window glass 5 during lifting and lowering. When the drive module is in operation, it drives the second outer water deflector 3 to switch between the first and second positions, thereby causing the second lip 31 of the second outer water deflector 3 to scrape the outer surface of the side window glass 5. The second outer water deflector 3 is positioned close to the rearview mirror, meaning the second lip 31 actively scrapes the rearview mirror's field of vision area of ​​the side window glass 5 to quickly remove water mist and frost, ensuring the driver can clearly see the rearview mirror through the side window glass 5 and drive safely. The second lip 31 of the second outer water deflector 3 can actively scrape the rearview mirror's field of vision area of ​​the side window glass 5, solving the technical problem in the prior art that the side window glass 5 cannot actively remove water mist and frost from the rearview mirror's field of vision area when stationary.

[0100] The side window glass water-blocking device also includes a heating component, which includes a heating wire 4. The heating wire 4 is disposed inside the second outer water-blocking strip 3 and extends along the length direction of the second outer water-blocking strip 3. The heating wire 4 is disposed near the second lip 31 of the second outer water-blocking strip 3.

[0101] In low-temperature conditions with severe frost or condensation, relying solely on the rotating scraping action of the second outer water-blocking strip 3 is insufficient to completely remove frost or water film. The heating wire 4, located near the second lip 31, can transmit heat to the side window glass 5 through the second lip 31, thereby softening the frost and evaporating the water film. This greatly reduces the adhesion between the glass surface and the second lip 31, effectively removing water stains or ice crystals that have been weakened by heat, improving cleaning efficiency, and avoiding incomplete scraping or mechanism overload caused by hard foreign objects.

[0102] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0103] 1. The second outer water deflector 3 is positioned close to the rearview mirror. The second outer water deflector 3 can switch between a first position and a second position so that the second lip 31 of the second outer water deflector 3 can scrape the outer surface of the side window glass 5. That is, the second lip 31 actively scrapes the rearview mirror field of view area of ​​the side window glass 5 to quickly remove water fog and frost from the rearview mirror field of view area, ensuring that the driver can clearly see the rearview mirror through the side window glass 5 and drive safely. This solves the technical problem in the prior art that the side window glass 5 cannot actively remove water fog and frost from the rearview mirror field of view area when it is stationary.

[0104] 2. In low-temperature frosting or severe condensation conditions, relying solely on the rotating scraping of the second outer water baffle 3 is insufficient to completely remove frost or water film. The heating wire 4 located near the second lip 31 can transfer heat to the side window glass 5 through the second lip 31, thereby softening the frost and evaporating the water film, greatly reducing the adhesion between the glass surface and the second lip 31. This can efficiently remove water stains or ice crystals that have been weakened by heat, improve cleaning efficiency, and avoid incomplete scraping or mechanism overload caused by hard foreign objects.
