Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, and in particular to a rain guard trim structure and its relation to a vehicle and electronic control system. Background Technology

[0002] As a means of transportation, cars have become an indispensable part of people's lives. To keep the air inside the car fresh and clean, one can simply open the windows to refresh the air. However, in some situations, opening the windows directly can lead to a poor user experience. For example, in rainy weather, opening the windows allows rainwater to enter the car; in windy and dusty weather, opening the windows allows sand and dust to enter directly. To overcome these problems, rain guards are now commonly installed on car windows.

[0003] Currently, car window rain guards are a type of automotive protective accessory, consisting of a protruding rain flap installed at the top edge of the car window. The main function of car window rain guards is to allow air circulation in situations where it's impossible to open the windows during rainy or sandy weather, while preventing wind and sand from blowing directly into the car or rainwater from flowing in. This overcomes the disadvantage of not being able to open windows while driving in rainy or sandy conditions.

[0004] Currently, the most common type of weatherstripping on the market is the adhesive rain guard, which is generally made of rubber or plastic and is attached to the original door trim using adhesive backing to achieve both rain protection and decorative purposes. However, the above-mentioned rain guards have a number of problems that urgently need to be solved.

[0005] First, since the current rain guards are fixed by adhesive, the overall installation is inconvenient. When pasting them on the original car trim, they are easy to be installed crookedly and protrude from the car body. After a long time, residual glue will easily overflow, affecting the appearance of the vehicle.

[0006] Secondly, the adhesive strength of the rain guards decreases after prolonged exposure to rain and sunlight, making them prone to loosening and compromising safety. This is especially true while the vehicle is in motion, where external forces such as wind pose a significant risk of detachment. Once the rain guards come loose, they can endanger following vehicles and compromise traffic safety.

[0007] Secondly, since the materials of these rain guards are generally rubber, plastic, etc., they will become brittle and lose their toughness after being exposed to the sun for a long time, resulting in low durability and reliability.

[0008] Finally, when the rainfall is heavy enough, even existing rain guards cannot effectively prevent rainwater from flowing into the car.

[0009] Therefore, it is necessary to propose a weatherstripping structure to solve at least one of the above problems. Summary of the Invention

[0010] To address the shortcomings of existing technologies, this invention provides a rain guard strip structure, a vehicle, and an electronic control system that can automatically close the windows when rainfall reaches a certain level. The system is aesthetically pleasing, safe, reliable, and durable.

The rain sensor component is disposed on the second structure and is used to receive rainfall information and send signals to the controller of the external device.

[0013] In a preferred embodiment, the main structure is formed by extrusion and bending of aluminum alloy material.

[0014] In a preferred embodiment, the rainfall sensing component includes a rainfall sensor with a sensing end that is not covered by the second structure.

[0021] In a preferred embodiment, the first structure has a first surface facing the vehicle body and a second surface for engaging with the door glass, the second surface being provided with a first seal for sealing engagement with the door glass.

[0022] In a preferred embodiment, the first surface of the first structure is further provided with a second seal at least at the location where it connects with the vehicle body.

[0023] A vehicle includes any of the above-described rain guard strip structures; the vehicle further includes a vehicle body, the vehicle body including a body sheet, a door disposed on the body sheet, a door glass disposed on the door, and a motor for driving the door glass to rise and fall.

[0024] In a preferred embodiment, the door is a frameless door, the rain guard strip structure is connected to the body sheet metal and located above the door, and the rain guard strip structure can form a seal with the door glass.

[0025] In a preferred embodiment, when the door glass rises to form a seal with the rain guard structure, the height difference between the highest position of the door glass and the lowest position of the second structure is less than the preset descent distance of the door glass for opening the door.

[0060] This invention provides a rain guard strip structure and a vehicle and electronic control system that can automatically close the windows when the rainfall reaches a certain level, and is aesthetically pleasing, safe, reliable and durable overall.

[0061] Please refer to the following for comprehensive information. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 10This application specification provides a rain guard strip structure 100, which may include a main structure and a rain sensor component 20. The main structure includes an integrally formed first structure 1 and a second structure 2. One side of the first structure 1 can serve as a side trim strip of an external vehicle body 200 and can be detachably connected to the external vehicle body 200. The other side of the first structure 1 is provided with the second structure 2, which can at least be used for rain protection. The rain sensor component 20 is disposed on the second structure 2 and is used to receive rainfall information and send signals to the controller of the external device.

[0062] The rain guard strip structure 100 provided in the embodiments of this application mainly includes: an integrally formed main structure and a rain sensing component 20 for sensing rainfall. The application will be described in detail below with reference to specific drawings and embodiments.

[0063] The main structure may include a first structure 1 serving as a side panel trim strip and a second structure 2 that can at least provide rain protection. When the main structure integrates the first structure 1 (as a side panel trim strip) and the second structure 2 (for rain protection, i.e., a rain guard structure) in a one-piece molding process, it not only retains the existing rain guard function but also eliminates the need for post-installation since the second structure 2 is integrally molded with the first structure 1. This solves a series of problems associated with the current method of adhesive-attach rain guards. Overall, the product is reliable and durable, poses no safety hazards during driving, and also has a decorative effect, enhancing the appearance of the vehicle.

[0064] The main structure is primarily formed by extrusion. Specifically, the main structure can be manufactured through processes such as extrusion, bending, and milling. When a mounting portion for the rain sensor component 20 needs to be formed at a predetermined location on the main structure, the mounting portion can be in the form of an opening. This opening on the main structure can be punched after the main structure is manufactured.

[0065] The main structure can be made of aluminum alloy, more preferably aluminum-magnesium-silicon alloy, which is a heat-treatable aluminum alloy with moderate strength, high corrosion resistance, good uniformity, good formability and processability, and is mainly used for extruded profiles. In other embodiments, the aluminum alloy material can be selected according to the product performance requirements, and this application does not impose specific limitations on it.

[0066] For example, when the main structure is formed by extrusion and bending of aluminum alloy material, the wall thickness of the main structure is generally not less than 1.2 mm, that is, the minimum thickness of the main structure is 1.2 mm. When the wall thickness of the aluminum alloy main structure is not less than 1.2 mm, it can ensure that the main structure has high strength and good performance. Of course, with the improvement of aluminum alloy material manufacturing process, the wall thickness of the main structure may also be less than 1.2 mm. Overall, this application does not make any special limitation on the wall thickness value of the main structure.

[0067] Please refer to the following: Figure 1 and Figure 7 The overall extension direction of the main structure matches the location where the rain guard strip structure 100 needs to be installed.

[0068] In some application scenarios, the rain guard strip structure 100 is used to be installed on the door frame of a framed door or on the body sheet metal 220 above a frameless door. Along the extension direction of the main structure, the position of the main structure matches the structure and position of the top of the door glass 210.

[0069] like Figure 7 As shown, in the embodiments of this application, the rain guard strip structure 100 is mainly used in the scenario of frameless car door as an example for detailed explanation. Other application scenarios can be compared with this scenario, and will not be described in detail here.

[0070] When the rain guard trim structure 100 is installed on the body sheet metal 220 above the door, its downward projection can cover the window. For example, the first end 101 of the rain guard trim structure 100 can be approximately close to the A-pillar of the vehicle body, and the second end 102 can be approximately close to the position of the triangular glass frame of the vehicle body.

[0071] In one embodiment, when the rain guard strip structure 100 is used to install on the body sheet 220 above the frameless door, the position of the rain sensor component 20 on the second structure 2 is matched with the position of the front door glass 210.

[0072] In this embodiment, for vehicles equipped with front and rear door windows 210, the rain guard strip structure 100 can be provided with a rain sensing component 20 above the position corresponding to the front door window 210, so that the rain sensing component 20 can accurately obtain the real rainfall of the current vehicle environment.

[0073] like Figure 6 and Figure 10As shown, surface A of this rain guard strip structure 100 is the area exposed to rain, and it simultaneously receives rain sensors in the X, Y, and Z directions. The X direction is the forward / backward direction of vehicle movement; the Z direction is the vertical direction perpendicular to the X direction; and the Y direction is the horizontal direction perpendicular to both the X and Z directions.

[0074] If sensors are installed on the windshield, when a vehicle is traveling at high speed, even a small amount of rain will accelerate and accumulate in the X-axis direction, impacting the windshield (because the speed of rain is constant, while the speed of the car is variable; a high-speed vehicle hitting raindrops will cause the raindrops to experience a greater amount of rain on the windshield in a short period than the actual rainfall). This will inevitably cause the sensor to misjudge the situation, leading to the automatic closing of the window, even though the actual amount of rain in the Y-axis direction may not be significant.

[0075] In the embodiments of this application, the rain sensor 20 is installed on the second structure 2 of the above-mentioned rain guard strip structure 100. The installation of the rain sensor 20 on the second structure 2 at the above-mentioned position can reduce the impact of X-direction rainwater when the vehicle is traveling at high speed, which may lead to the window being closed accidentally.

[0076] In the above embodiment, when the rainfall sensing component 20 senses that the current rainfall reaches a preset rainfall level, the controller and the motor used to move the door glass 210 up and down can simultaneously close the front and rear windows that are not closed. Alternatively, for the same vehicle, a rain guard strip structure 100 with the rainfall sensing component 20 can be installed on one side of the vehicle body along the Y direction, while only a one-piece main structure is installed on the other side. When the rainfall sensing component 20 senses that the current rainfall reaches a preset rainfall level, the controller and the motor used to move the door glass 210 up and down can simultaneously close all the windows that are not closed.

[0077] In another embodiment, when the rain guard strip structure 100 is used to install on the body sheet metal 220 above the frameless door, the second structure 2 includes multiple sets of rain sensing components 20, the number of which can be matched with the number of doors, and the installation position of the rain sensing components 20 is matched with the position of the door glass 210 of each door.

[0078] In this embodiment, for scenarios with multiple doors, such as at least front and rear doors, the amount of rain sensed at different door positions may differ. By setting rain sensing components 20 at positions corresponding to different door windows 210, each door window 210 can be controlled individually, so that the automatic closing of each window is directly matched with the currently detected amount of rain, further improving the control accuracy.

[0079] Since the main structure is formed by extrusion, this application specification mainly provides a more detailed description of its cross-sectional structure.

[0080] Please refer to the following: Figure 2 , Figure 3 , Figure 4 and Figure 5 The integrally formed main structure may include a first structure 1 for use as a side panel trim and a second structure 2 for at least rain protection.

[0081] The first structure 1 is used for detachable connection with the vehicle body 200. Specifically, the first structure 1 can be fixed to the vehicle body 200 by rivet nuts or screws. Of course, the specific connection method between the first structure 1 and the vehicle body 200 can also be other methods, and is not limited to the above description. Those skilled in the art may make other modifications based on the technical essence of this application, but as long as the function and effect achieved are the same as or similar to this application, they should be covered within the protection scope of this application.

[0082] The specific shape and construction of the first structure 1 can vary depending on the specific application of the rain guard trim structure 100, and this application does not impose any special limitations. For example, when the rain guard trim structure 100 is applied to a frameless car door model, the first structure 1 can adopt the side trim strip of a frameless car door model on the market, and the shape and structure of the side trim strip are not limited here.

[0083] Please refer to the following: Figure 8 and Figure 9 In one embodiment, the first structure 1 has a first surface 11 facing the vehicle body 200 and a second surface 12 for engaging with the door glass 210. The second surface 12 is provided with a first sealing element 41 for sealingly engaging with the door glass 210. When the window is closed, the height difference between the highest position of the door glass 210 and the lowest position of the second structure 2 is less than a preset descent distance of the door glass 210 for opening the door.

[0084] In addition, the first surface 11 of the first structure 1 is provided with a second seal 42 at least at the position where it is connected to the vehicle body 200.

[0085] In this embodiment, a second sealing element 42 may be provided between the first structure 1 and the vehicle body 200 to ensure the sealing of the mating position between the first structure 1 and the vehicle body 200. Specifically, the form of the second sealing element 42 is not specifically limited here; it may be in the form of sealant or a sealing ring, etc. In addition to the second sealing element 42, sound-absorbing and vibration-damping materials such as foam may also be provided between the first structure 1 and the vehicle body 200.

[0086] The area enclosed by the second surface 12 of the first structure 1 is mainly the space for the door glass 210 to rise and fall. When the door glass 210 is raised to its highest position, in order to avoid the glass from colliding with the first structure 1 while ensuring a seal, a first sealing element 41 can be added to the area enclosed by the second surface 12 of the first structure 1. The first sealing element 41 can be in the form of a sealing strip with a certain deformation capability, which can be installed in the area enclosed by the second surface 12 by means of snap-fit ​​or adhesive. Of course, the specific shape and structure of the first sealing element 41 are not specifically limited in this application.

[0087] In a specific application scenario, when the rain guard structure 100 is used in a frameless car door setting, the frameless door glass 210 will rise to the top and press against the first seal 41 when fully closed to ensure a tight seal. When the frameless door is opened, to disengage from the first seal 41 and prevent interference between the door glass 210 and the vehicle body 200, the door glass 210 can be automatically lowered by 5mm to 30mm. This automatic lowering distance of the door glass 210 is primarily illustrated using the current frameless car door scenario. In other scenarios, or with improvements to the structure of the vehicle body 200 and the door, the automatic lowering distance of the door glass 210 may not be limited to the above example.

[0088] Based on the value of the descent of the door glass 210, the height difference between the highest position of the door glass 210 and the lowest position of the second structure 2 is less than the preset descent distance of the door glass 210 for opening the door (e.g., ...). Figure 9 As shown, the height difference D value should be less than the value of the glass drop (to avoid interference between the door glass 210 and the second structure 2 when the door is opened, while ensuring the rainproof function of the second structure 2).

[0089] like Figure 3 and 5 As shown, the second structure 2 can not only block rain, but also provide space for the rain sensing component 20 to identify the amount of rain, thereby enabling the vehicle to automatically close the windows when encountering heavy rain.

[0090] In one embodiment, the rainfall sensing component 20 may include a rainfall sensor having a sensing end that is not covered by the second structure 2. The sensing end not covered by the second structure 2 is used to directly or indirectly sense rainfall. Specifically, the installation method of the rainfall sensor, the location and setting method of the sensing end may vary depending on the type of rainfall sensor.

[0091] In some embodiments, the rain sensor may be fixedly connected to the side of the second structure 2 away from the first structure 1; or, the second structure 2 is provided with a signal transmission hole 30, the rain sensor is fixedly connected to the side of the second structure 2 close to the first structure 1, and the sensing end is located at the signal transmission hole; or, the second structure 2 is provided with a signal transmission hole 30, and the rain sensor is fixedly connected inside the signal transmission hole 30.

[0092] Specifically, the rain sensor is either a photosensitive rain sensor 31 or a piezoelectric rain sensor. Of course, other types of sensors can also be used to detect the rainfall signal. When the rain sensor is a piezoelectric rain sensor, it can be fixedly connected to the side of the second structure 2 facing away from the first structure 1.

[0093] When the rain sensor is a light-sensitive rain sensor 31, the rain sensing component 20 may also include a light-transmitting sheet 32, which is fixedly connected to the signal transmission hole 30 of the second structure 2.

[0094] The light-transmitting sheet 32 ​​includes a first surface 11 that can contact rainwater and a second surface 12 opposite to the first surface 11. The light-sensitive rain sensor 31 can be located on the second structure 2 directly opposite the second surface 12.

[0095] Furthermore, the signal transmission hole 30 is provided with a stepped countersunk hole 301, the countersunk hole 301 is located on the side of the second structure opposite to the first structure 1, and the light-transmitting sheet is fixedly connected to the countersunk hole 301.

[0096] In this embodiment, the sensor used to detect rainfall signals in the rainfall sensing component 20 is mainly described in detail using a photosensitive rainfall sensor 31 as an example. Of course, the sensor used to detect rainfall signals can also take other forms, such as a piezoelectric rainfall sensor. If a piezoelectric rainfall sensor is used, an opening for introducing rainwater can be made in the second structure 2. This opening is connected to the sensing end of the piezoelectric rainfall sensor, and during use, the rainwater is guided to the sensing end through the opening. In this embodiment, the second structure 2 includes an outer wall 24 for contact with rainwater and an inner wall 23 opposite to the outer wall 24. The photosensitive rainfall sensor 31 is disposed on the inner wall 23 of the second structure 2 and does not directly contact the rainwater, resulting in high reliability and detection accuracy during use. Specifically, the photosensitive rainfall sensor 31 can be bonded to the surface of the inner wall 23 of the second structure 2 using a silicone pad.

[0097] The light-transmitting sheet 32 ​​may include a polycarbonate sheet, abbreviated as PC sheet. The refractive index of the polycarbonate sheet is 1.591. When the light-transmitting sheet 32 ​​is made of polycarbonate sheet, the manufacturing difficulty and cost are relatively low, making it suitable for mass production. Of course, when the manufacturing process reaches a certain level, the light-transmitting sheet 32 ​​may also be made of other materials with better light transmittance; however, this application does not make a specific limitation here.

[0098] In this embodiment, a signal transmission hole 30 is provided at a predetermined position on the second structure 2; a stepped countersunk hole 301 is provided inside the signal transmission hole 30; the thickness of the second structure 2 at the position of the signal transmission hole 30 is greater than the thickness at other positions; and the edge of the light-transmitting sheet 32 ​​is installed on the countersunk hole 301 by applying sealant.

[0099] In the actual manufacturing process, holes can be punched in the sidewall of the second structure 2, and polyurethane sealant can be applied to the edge of the PC sheet before it is installed on the countersunk hole 301. If the countersunk hole 301 is not machined, the thickness of the second structure 2 at the location of the countersunk hole 301 should be consistent with that of the main structure, i.e., 1.2mm. Due to the requirement of the countersunk hole 301, the structural strength can be ensured by thickening the inner sidewall 23 of the second structure 2, which facilitates the machining of the countersunk hole 301 and avoids the occurrence of thin-walled holes. The thickness of the inner sidewall 23 of the second structure 2 is equal to the depth of the countersunk hole 301, and the depth of the countersunk hole 301 is determined according to the thickness of the PC sheet; its specific value is not specifically limited in this application.

[0100] In one specific embodiment, the second structure 2 includes a bent portion 21 connected to the first structure 1 and an extension portion 22 connected to the bent portion 21. The rain sensing component 20 is disposed on the extension portion 22, and the cross-section of the extension portion 22 is generally straight.

[0101] like Figure 10 As shown, the vehicle's directions are divided into X, Y, and Z directions, which are respectively forward and backward, left and right lateral, and up and down longitudinal. The function of the second structure 2 is to provide rain protection and serve as a carrier for sensors. It is mainly divided into Z-direction and Y-direction structures, as shown... Figure 11 As shown, the second structure 2 protrudes more in the Y direction. In order to reduce the abruptness of the second structure 2, the distance between the second surface 12 of the first structure 1 and the inner wall 23 of the second structure 2 is as small as possible, and the structure is as simple as possible. In the Z direction, the extended part is straight in order to facilitate the installation of sensors and PC sheets.

[0102] In this embodiment, the rain sensing component 20 is electrically connected to the controller and sends signals to the peripheral controller. When the controller detects that the current rainfall sensed by the rain sensing component 20 has reached a preset rainfall level, the controller can issue a control command to close the windows. Of course, in addition to issuing the control command to close the windows, the controller can also issue other commands indicating that the current rainfall is too heavy and the windows need to be closed. For example, it can send a control signal to the center console, which then issues voice, image, or other prompts to the driver and passengers to remind them to close the windows in time.

[0103] In this embodiment, the rain sensing component 20 includes a light-sensitive rain sensor 31 as an example for further explanation.

[0104] Specifically, the light-sensitive rain sensor 31 mainly includes optical elements, far-infrared light-emitting diodes, photodiodes, etc. The far-infrared light-emitting diodes and photodiodes can be used to identify the amount of rainfall and the degree of humidity.

[0105] The rain sensor uses a relative measurement method. When the outer surface of the PC sheet is dry, it is assumed that the parallel light emitted by the LED is 100% reflected back after hitting the PC sheet. The reflected light is received by the photodiode through optical elements. The amount of rain on the PC sheet is inversely proportional to the amount of reflected light; that is, the more rain on the PC sheet, the less light is reflected back.

[0106] With the outer surface of the PC sheet dry, the sensor is first initialized to obtain the light intensity received under a fixed emission current. The light intensity is then converted into an electrical signal that the controller can recognize by the internal circuit of the photodiode. The controller determines the amount of rainfall based on the different input electrical signals and compares the current rainfall with the preset rainfall. When the current rainfall reaches the preset rainfall, the vehicle body controller can send a control command to close the windows via the LIN bus, and then drive the corresponding window regulator motor to close the windows. In cases of heavy rain or car washing, the system can automatically recognize and close the windows to prevent water from entering the vehicle.

[0107] Overall, the rain guard strip structure 100 provided in this application embodiment has an integrally formed main structure and a rain sensing component 20 for sensing rainfall. The main structure includes a first structure 1 serving as a side panel trim strip and a second structure 2 for at least rain protection. The rain sensing component is disposed on the second structure 2 and is electrically connected to a controller. When the controller detects that the current rainfall sensed by the rain sensing component has reached a preset rainfall level, the controller issues a control command to close the window. This rain guard strip structure 100 is reliable and durable, poses no safety hazards during driving, and has a decorative function, enhancing the vehicle's appearance. When applied to a vehicle, the rain guard strip structure 100 can automatically recognize and close the window during heavy rain or car washing, preventing water from entering the vehicle.

[0108] This application also provides a vehicle, which mainly includes the above-mentioned rain guard strip structure 100.

[0109] By setting the aforementioned rain guard trim structure 100, the vehicle can achieve the technical effect of the rain guard trim structure implementation method. For details, please refer to the specific description of the above implementation method, which will not be repeated here.

[0110] The vehicle also includes a vehicle body 200, which includes a body sheet 220, a door mounted on the body sheet 220, a door glass 210 mounted on the door, and a motor for driving the door glass 210 to move up and down.

[0111] The vehicle door can be divided into framed doors and frameless doors. When the vehicle door is a frameless door, the rain guard trim structure 100 is connected to the body sheet metal 220 and located above the door, and the rain guard trim structure 100 can form a seal with the door glass 210. When the vehicle door is a framed door, the door includes a door frame for cooperating with the door glass 210, and the rain guard trim structure 100 is connected to the door frame, and the rain guard trim structure 100 can form a seal with the door glass.

[0112] When the door is a frameless door, to avoid interference between the door glass 210 and the second structure 2 when the door is opened, and to ensure the rain-proof function of the second structure 2, when the door glass 210 rises to form a seal with the rain guard trim structure 100, the height difference D between the highest position of the door glass 210 and the lowest position of the second structure 2 is less than the preset lowering distance of the door glass 210 for opening the door. The preset lowering distance for opening the door can be from 5mm to 30mm. Of course, this preset lowering distance can vary depending on different vehicle models, and this application does not make a specific limitation here.

[0113] This application also provides an electronic control system applicable to the vehicle. The electronic control system further includes a controller, which is electrically connected to the rain sensing component 20 and a motor for driving the door glass 210 to rise and fall. When the controller recognizes that the signal emitted by the rain sensing component 20 meets preset conditions, such as when the current rainfall reaches a preset rainfall, the controller can start the motor to drive the door glass 210 to rise and close the window that is not closed.

[0114] The electronic control system can achieve the technical effect of the rain guard strip structure implementation by setting the rain guard strip structure 100. For details, please refer to the specific description of the above implementation, which will not be repeated here.
