Description

Technical Field

[0001] This invention relates to the field of vehicle manufacturing technology, and in particular to a rearview mirror structure, a control method for the rearview mirror structure, and a vehicle. Background Technology

[0002] With the development of the national economy and the continuous improvement of living standards, vehicles are becoming increasingly important in daily life and travel. Driving safety and ease of use are key considerations during vehicle manufacturing. Existing vehicles are equipped with rearview mirrors on the outside of both the driver's and passenger's seats, which can be used to observe road conditions to the driver's side and rear, ensuring driving safety.

[0003] When driving in the rain, raindrops can remain on the rearview mirror surface, affecting its reliability. While users can manually wipe away the raindrops, this is inconvenient. External wipers or a hydrophobic coating can be installed on the mirror to clear water droplets and ensure clear visibility for the driver. However, external wipers can obstruct the driver's view, creating blind spots and affecting driving safety. They are also complex and expensive. Hydrophobic coatings, on the other hand, have limited effectiveness in continuous or heavy rainfall, resulting in poor reliability and room for improvement. Summary of the Invention

[0025] The following is for reference. Figures 1-2 The rearview mirror structure 100 described in this embodiment of the invention avoids the need for an external cleaning structure, has a simple structure, and low installation cost, thus ensuring vehicle lightweighting and reliable use. It also prevents raindrops, dust, and other contaminants from remaining on the rearview mirror surface 2, thereby ensuring the driver's clear vision and improving driving safety.

[0026] like Figures 1-2 As shown, a rearview mirror structure 100 according to an embodiment of the present invention includes: a rearview mirror housing 1.

[0027] The rearview mirror housing 1 has an air intake channel for supplying air to the rearview mirror surface 2. The rearview mirror housing 1 has a separator 3 extending from top to bottom. The air intake channel includes a mixing section 11 and an outlet section 12. The mixing section 11 and the outlet section 12 are located on both sides of the separator 3 and are connected at the bottom of the separator 3. The rearview mirror housing 1 also has a drain outlet 13 connected to the air intake channel below the separator 3. The drain outlet 13 can be selectively opened.

[0028] Specifically, the rearview mirror structure 100 is provided with a rearview mirror housing 1. The rearview mirror structure 100 can be connected to the vehicle body through the rearview mirror housing 1, and the rearview mirror surface 2 is rotatably installed on the rearview mirror housing 1, which makes it convenient for users to adjust the viewing angle of the rearview mirror according to different seating positions, thereby ensuring the best observation angle of the side or rear road conditions and improving driving safety. An air intake channel is also formed inside the rearview mirror housing 1. The air intake channel can be constructed as an "S" shaped channel or a spiral channel, etc., and the air intake channel can supply air to the rearview mirror surface 2 to blow away raindrops or dust on the rearview mirror surface 2, ensuring the cleanliness of the rearview mirror surface 2, thereby ensuring the clarity of the driver's vision, improving driving safety, and avoiding the need for additional external cleaning structures. The structure is simple and the installation cost is low, thus ensuring the lightweight of the vehicle.

[0029] The air intake channel includes a mixing section 11 and an exhaust section 12, which are connected. The mixing section 11 is away from the rearview mirror surface 2 and connected to the outside. The exhaust section 12 is open to the rearview mirror surface 2, so that when the vehicle is moving, the airflow can flow along the outer peripheral wall of the rearview mirror housing 1 into the mixing section 11, and then blow towards the rearview mirror surface 2 through the exhaust section 12. A separator 3 is also provided inside the rearview mirror housing 1. The upper end of the separator 3 can be connected to the inner wall of the rearview mirror housing 1 and extends from top to bottom. That is, the separator 3 can be set to extend downward in the vertical direction or in a direction with an angle to the vertical direction.

[0030] Furthermore, the mixing section 11 and the outlet section 12 are located on both sides of the separator 3 and connected at the bottom of the separator 3. This allows the airflow mixed with rainwater to be separated by the separator 3 when the vehicle is driving in the rain. The rainwater can flow downward along the separator 3 under the action of gravity and gather below the separator 3. The airflow can also blow the rearview mirror 2 through the outlet section 12. A drain outlet 13 is provided on the rearview mirror housing 1. The drain outlet 13 is located below the separator 3 and can be selectively opened. This allows the rainwater and impurities separated by the separator 3 to be discharged from the rearview mirror housing 1 through the drain outlet 13 after a certain amount has gathered below the separator 3. This ensures the connectivity of the air intake channel, thus ensuring the reliability of the air intake channel. The structure is simple and the installation cost is low.

[0031] According to the rearview mirror structure 100 of the present invention, an air intake channel for supplying air to the rearview mirror surface 2 is formed in the rearview mirror housing 1, thereby blowing away raindrops or dust on the rearview mirror surface 2. This avoids the need for an external cleaning structure, resulting in a simple structure and low installation cost, thus ensuring vehicle lightweighting. Furthermore, the mixing section 11 and the exhaust section 12 of the air intake channel are located on both sides of the separator 3, allowing the separator 3 to separate airflow and rainwater. At the same time, the drain outlet 13 below the separator 3 can be selectively opened, allowing the rainwater separated by the separator 3 to be discharged from the rearview mirror housing 1 through the drain outlet 13. This ensures the reliability of the air intake channel for exhausting air to the rearview mirror surface 2, preventing raindrops, dust, etc. from remaining on the rearview mirror surface 2, thereby ensuring the driver's clear vision, improving driving safety, and providing good performance with a wide range of applications.

[0032] In some embodiments, the separator 3 is formed with at least two guide holes 31 extending through the separator 3 in the thickness direction, and the at least two guide holes 31 are connected between the mixing section 11 and the outlet section 12.

[0033] Specifically, such as Figures 1-2As shown, the separator 3 is provided with guide holes 31. There can be at least two guide holes 31, that is, there can be two, three or four guide holes 31. In this embodiment, there are six guide holes 31. At least two guide holes 31 are spaced apart along the extension direction of the separator 3, and the guide holes 31 penetrate the separator 3 along the thickness direction. That is, the extension direction of the guide holes 31 can coincide with the thickness direction of the separator 3, or it can have an angle with the thickness direction of the separator 3. The separator 3 extends from top to bottom, so that the guide holes 31 can connect between the mixing section 11 and the outlet section 12.

[0034] Thus, when the airflow mixed with rainwater flows through the mixing section 11 to the separator 3, the airflow can flow directly into the outlet section 12 through the guide hole 31, and the rainwater in the airflow can flow downward through the separator 3 to converge at the drain outlet 13. Furthermore, the airflow mixed with rainwater can be further separated at the guide hole 31, improving the reliability of the separator 3. In addition, at least two guide holes 31 are provided, allowing the airflow mixed with rainwater to be separated through at least two guide holes 31 respectively, ensuring effective separation.

[0035] In some embodiments, the guide hole 31 extends horizontally, or the guide hole 31 extends upward from the mixing section 11 to the outlet section 12.

[0036] Specifically, the separator 3 is provided with a guide hole 31, and as follows: Figure 1 As shown, the separator 3 is configured to extend vertically from top to bottom, and the guide hole 31 is configured to extend horizontally, that is, the guide hole 31 is horizontally connected between the mixing section 11 and the outlet section 12. Alternatively, the guide hole 31 is configured to extend upward from the mixing section 11 to the outlet section 12, that is, the end of the guide hole 31 connected to the mixing section 11 is located below the end of the guide hole 31 connected to the outlet section 12. The configuration is flexible.

[0037] In this way, part of the mixed rainwater airflow flowing to the separator 3 can be separated by the separator 3 and flow from below the separator 3 into the air outlet section 12. The other part of the mixed rainwater airflow can be separated by the guide hole 31. The separated airflow can flow into the air outlet section 12 and blow towards the rearview mirror 2 through the air outlet section 12 to ensure the blowing effect.

[0038] Furthermore, the guide hole 31 is configured to extend upward from the mixing section 11 to the outlet section 12, so that when the airflow mixed with rainwater flows into the guide hole 31, the rainwater in the airflow can flow into the mixing section 11 under the action of gravity, and then converge to the drain outlet 13, thereby improving the separation effect of the guide hole 31 and ensuring the reliability of the separator 3.

[0039] In some embodiments, the mixing section 11 further includes a bent and connected inlet section 111 and a split section 113, the split section 113 and the outlet section 12 are connected and located on both sides of the separator 3, wherein the rearview mirror housing 1 is formed with an inlet 112 and an outlet 121, the inlet section 111 is connected to the inlet 112, and the outlet 121 is connected to the upper end of the outlet section 12 and is open toward the rearview mirror surface 2.

[0040] Specifically, such as Figures 1-2 As shown, the mixing section 11 is provided with an inlet section 111 and a branch section 113, which are bent and connected. The rearview mirror housing 1 has an inlet 112 and an outlet 121. The inlet 112 is connected to the inlet section 111, and the outlet 121 is connected to the outlet section 12. The outlet 121 is open towards the rearview mirror surface 2, so that the airflow mixed with rainwater can enter the inlet section 111 from the inlet 112 and flow through the inlet section 111. The flow path leads to the diversion section 113, where the inlet section 111 and the diversion section 113 are bent and connected, which can pre-separate the airflow mixed with rainwater. The diversion section 113 and the outlet section 12 are located on both sides of the separator 3, so that when the airflow mixed with rainwater flows to the diversion section 113, air-water separation can be performed in the separator 3. The separated airflow can be blown through the outlet 121 of the outlet section 12 to clean the rearview mirror 2, ensuring the reliability of cleaning the rearview mirror 2.

[0041] In actual installation, the air outlet 121 is formed on the rear side of the rearview mirror housing 1 and connected to the upper end of the air outlet section 12, so that the air outlet 121 is located above the rearview mirror surface 2, thereby allowing rainwater on the rearview mirror surface 2 to flow downward under the action of gravity and gas, ensuring the reliability of purging. The inlet 112 can be set on the front side or the left and right sides of the rearview mirror housing 1. In this embodiment, the inlet 112 is formed on the front side of the rearview mirror housing 1, so that when the vehicle is driving, the airflow can flow directly into the inlet 112, increasing the gas flow rate entering the air intake channel, thereby ensuring the reliability of purging the rearview mirror surface 2.

[0042] In some embodiments, the rearview mirror housing 1 is further formed with a selectively opening cleaning port 14, which communicates with the airflow section 12 and / or the mixing section 11.

[0043] Specifically, such as Figures 1-2 As shown, the rearview mirror housing 1 also has a cleaning port 14. The cleaning port 14 is located at the upper part of the rearview mirror housing 1 and is connected to the air outlet section 12 and / or the mixing section 11. That is, the cleaning port 14 may be connected only to the air outlet section 12, or only to the mixing section 11, or both the air outlet section 12 and the mixing section 11 may be connected. Figure 1As shown, the cleaning port 14 is only connected to the airflow outlet section 12, as... Figure 2 As shown, the cleaning port 14 is connected to the air outlet section 12 and the mixing section 11, allowing users to clean the air inlet channel through the cleaning port 14. The cleaning port 14 is also connected to the drain port 13 through the air outlet section 12 and the mixing section 11, allowing users to clean or unclog the drain port 13 through the cleaning port 14, ensuring the reliability of the drain port 13.

[0044] In some other embodiments, the rearview mirror structure 100 further includes a drive structure, the drain outlet 13 is provided with a first cover plate 131, the drive structure is poweredly connected to the first cover plate 131 and is adapted to drive the first cover plate 131 to open or close the drain outlet 13.

[0045] Specifically, such as Figures 1-2 As shown, the drain outlet 13 is also provided with a first cover plate 131, which is rotatably installed at the drain outlet 13. The rearview mirror structure 100 is also provided with a drive structure, which is poweredly connected to the first cover plate 131. This allows the drive structure to drive the first cover plate 131 to open or close the drain outlet 13, thereby enabling the drain outlet 13 to selectively drain water. That is, when the user needs to blow clean the rearview mirror surface 2, the drive structure can drive the first cover plate 131 to close the drain outlet 13 to ensure the airflow to the rearview mirror surface 2, thus ensuring the reliability of blowing clean the rearview mirror surface 2. After blowing clean for a period of time, a certain amount of rainwater accumulates at the drain outlet 13. The drive structure can then drive the first cover plate 131 to open the drain outlet 13 to discharge the rainwater in the air intake channel, ensuring the reliability of the air intake channel.

[0046] In addition, such as Figures 1-2 As shown, a second cover plate 141 is also provided at the cleaning port 14. The second cover plate 141 is rotatably installed on the cleaning port 14. The user can manually open or close the second cover plate 141, so that the cleaning port 14 can be sealed when cleaning is not required, to prevent dust and other objects from falling into the air intake channel and to ensure the reliability of the cleaning port 14.

[0047] In actual setup, an oleophobic coating can also be applied to the rearview mirror surface 2. The oleophobic coating can be nano-SiO2 to accelerate the sliding of rainwater. The drive structure can also be linked with the vehicle interface or mechanical switch, allowing users to manually control the opening or closing of the first cover 131 to meet different usage needs. Furthermore, the diameter of the drain outlet 13 is set to be larger than the diameter of the inlet 112 to avoid large particles of impurities from getting stuck and to ensure drainage reliability.

[0048] The present invention also proposes a method for controlling the structure of a rearview mirror.

[0049] The control method for the rearview mirror structure according to an embodiment of the present invention is applicable to the rearview mirror structure 100 described above, such as... Figure 3 As shown, the control methods include: S1. Obtain the current rainfall intensity and the vehicle's current speed; S2. Based on the current rainfall intensity and current vehicle speed, control the drainage outlet 13 to open at the first set interval.

[0050] Specifically, when the vehicle is driving in the rain, the airflow mixed with rainwater can enter the air intake duct through the inlet 112, and the airflow after being separated by the separator 3 in the air intake duct can be blown onto the rearview mirror surface 2 through the outlet 121 to ensure the reliability of the rearview mirror structure 100. When the vehicle speed increases, the flow rate of the airflow mixed with rainwater entering the air intake duct will also increase, thereby increasing the flow rate of rainwater entering the air intake duct. When the rainfall increases, the amount of rainwater mixed in the airflow will also increase.

[0051] The vehicle is equipped with a body domain controller, which can obtain the current rainfall intensity outside the vehicle and the current vehicle speed. It can then control the drive structure according to the current rainfall intensity and the current vehicle speed, so that the drive structure drives the first cover 131 to open at a first set time interval, and then drains water through the drain outlet 13.

[0052] Furthermore, when the current rainfall intensity is high or the current vehicle speed is high, the amount of rainwater entering the air intake duct increases, thereby shortening the first set duration to increase the drainage frequency and ensure the reliability of the air intake duct. Conversely, when the current rainfall intensity is low or the current vehicle speed is slow, the amount of rainwater entering the air intake duct decreases, thereby increasing the first set duration to reduce the drainage frequency. This, in turn, reduces the number of times the drive structure is started, saving energy.

[0053] According to the control method of the rearview mirror structure of the present invention, the drain outlet 13 is controlled to open for different first set durations according to the current rainfall intensity and the current vehicle speed. This can save energy consumption of the drive structure while ensuring the reliability of the air intake channel, thereby ensuring the reliability of the rearview mirror structure 100, improving driving safety, reducing overall vehicle energy consumption, improving vehicle range performance, and improving user experience.

[0054] In some embodiments, such as Figure 4 As shown, obtaining the current rainfall intensity includes: S11. Obtain the current reflectivity of rearview mirror 2; S12. Based on the current reflectivity of the rearview mirror 2, determine the intensity level of the current rainfall.

[0055] Specifically, the vehicle domain controller can acquire the current rainfall intensity, and the rearview mirror structure 100 is equipped with an infrared reflective rain light sensor. The infrared reflective rain light sensor is installed on the inner side of the rearview mirror surface 2, and can determine the current rainfall intensity by measuring the current reflectivity of the rearview mirror surface 2. That is, when there is a lot of rain on the rearview mirror surface 2, the current reflectivity of the rearview mirror surface 2 decreases, indicating a higher intensity level of the current rainfall. When there is little rain on the rearview mirror surface 2, the current reflectivity of the rearview mirror surface 2 increases, indicating a lower intensity level of the current rainfall. The infrared reflective rain light sensor can be electrically connected to the vehicle domain controller, thereby enabling the infrared reflective rain light sensor to transmit the measured current reflectivity to the vehicle domain controller. The vehicle domain controller determines the intensity level of the current rainfall based on the current reflectivity and controls the opening frequency of the first cover 131 based on the intensity level of the current rainfall, thereby improving intelligence and the reliability of the rearview mirror structure 100.

[0056] In some embodiments, such as Figure 5 As shown, based on the current reflectivity of rearview mirror 2, the intensity level of the current rainfall is determined by: S121. When the current reflectivity is in the first reflectivity range, the intensity level is determined to be Level 1. S122. When the current reflectivity is in the second reflectivity range, the intensity level is determined to be level two. S123. When the current reflectivity is in the third reflectivity range, the intensity level is determined to be level three. S124. When the current reflectivity is in the fourth reflectivity range, the intensity level is determined to be level four. S125. When the current reflectivity is in the fifth reflectivity range, the intensity level is determined to be level five.

[0057] Specifically, the infrared reflective rain sensor can acquire the current reflectivity, and the vehicle domain controller can determine the intensity level of the current rainfall based on the current reflectivity. When the current reflectivity is in the first reflectivity range, the intensity level can be determined to be Level 1; when the current reflectivity is in the second reflectivity range, the intensity level can be determined to be Level 2; when the current reflectivity is in the third reflectivity range, the intensity level can be determined to be Level 3; when the current reflectivity is in the fourth reflectivity range, the intensity level can be determined to be Level 4; and when the current reflectivity is in the fifth reflectivity range, the intensity level can be determined to be Level 5.

[0058] Furthermore, in actual settings, the intensity levels 1, 2, 3, 4, and 5 can correspond to light rain, moderate rain, heavy rain, and storm, respectively. The current reflectivity is set to R, and the first reflectivity range can be set as follows: 80%≤R<90%, 60%≤R<80%, 40%≤R<60%, 30%≤R<40%, and R<30%. The vehicle domain controller can judge the intensity level based on the above ranges and adjust the operating frequency of the drive structure accordingly to improve intelligence and ensure the reliability of cleaning the rearview mirror surface 2.

[0059] In addition, the intensity level and reflectivity range can be adjusted according to the actual situation during actual setup, increasing the flexibility of use and making it suitable for different usage scenarios.

[0060] In some embodiments, such as Figure 6 As shown, the control of opening the drain outlet 13 at first set intervals according to the intensity level and the current vehicle speed includes: S21. Based on the current rainfall intensity level and the current vehicle speed, obtain the corresponding preset duration from the preset intensity level and vehicle speed versus preset duration table; S22. Set the preset duration as the first set duration and control the drain outlet 13 to open at preset intervals.

[0061] Specifically, the vehicle's CAN bus is electrically connected to the body domain controller, which can then transmit the vehicle's current speed information to the body domain controller. The body domain controller has a preset intensity level and a relationship table between vehicle speed and set duration. The body domain controller can select the current rainfall intensity level and the preset duration corresponding to the current vehicle speed according to the relationship table, and use the preset duration as the first set duration. This allows the body domain controller to adjust the first set duration in real time according to the current rainfall intensity level and the current vehicle speed, so as to control the drainage outlet 13 to open at preset intervals, ensuring drainage reliability.

[0062] In practice, the relationship lookup table can be set as follows: When the vehicle speed is between 0 km / h and 100 km / h and the intensity level is Level 1, the control drain outlet 13 drains water once every 30 minutes; when the vehicle speed is between 0 km / h and 100 km / h and the intensity level is Level 2, the control drain outlet 13 drains water once every 20 minutes; when the vehicle speed is between 0 km / h and 100 km / h and the intensity level is Level 3, the control drain outlet 13 drains water once every 10 minutes; when the vehicle speed is between 0 km / h and 100 km / h and the intensity level is Level 4, the control drain outlet 13 drains water once every 3 minutes; and when the vehicle speed is between 0 km / h and 100 km / h and the intensity level is Level 5, the control drain outlet 13 drains water once every minute.

[0063] When the vehicle speed is greater than 100 km / h and the strength level is Level 1, the control drain outlet 13 drains water once every 20 minutes; when the vehicle speed is greater than 100 km / h and the strength level is Level 2, the control drain outlet 13 drains water once every 10 minutes; when the vehicle speed is greater than 100 km / h and the strength level is Level 3, the control drain outlet 13 drains water once every 3 minutes; when the vehicle speed is greater than 100 km / h and the strength level is Level 4 and Level 5, the control drain outlet 13 drains water once every minute.

[0064] Furthermore, the speed range and interval can be adjusted according to actual conditions, improving the flexibility and applicability of use.

[0065] The opening and closing cycle of the first cover plate 131 can be set to control the first cover plate 131 to be fully opened, with a time of 2 seconds; control the first cover plate 131 to be stopped, with a time of 2 seconds; and control the first cover plate 131 to be fully closed, with a time of 2 seconds, to ensure that the drain outlet 13 drains completely. In actual settings, the opening and closing cycle duration can be adjusted according to the size of the drain outlet 13 to ensure the reliability of the drain outlet 13.

[0066] The present invention also proposes a vehicle.

[0067] The vehicle according to an embodiment of the present invention includes the rearview mirror structure 100 of any of the above claims.

[0068] According to an embodiment of the present invention, a vehicle is provided with a rearview mirror structure 100. The rearview mirror structure 100 forms an air intake channel in the rearview mirror housing 1 to supply air to the rearview mirror surface 2, thereby blowing away raindrops or dust on the rearview mirror surface 2. This avoids the need for an external cleaning structure, resulting in a simple structure and low installation cost, thus ensuring the vehicle's lightweight design. The mixing section 11 and the exhaust section 12 of the air intake channel are located on both sides of the separator 3, allowing the separator 3 to separate airflow and rainwater. At the same time, the drain outlet 13 below the separator 3 can be selectively opened, allowing the rainwater separated by the separator 3 to be discharged from the rearview mirror housing 1 through the drain outlet 13. This ensures the reliability of the air intake channel's exhaust to the rearview mirror surface 2, preventing raindrops, dust, etc., from remaining on the rearview mirror surface 2, thereby ensuring the driver's clear vision, improving driving safety, and providing good performance with a wide range of applications.
