Description

Technical Field

[0001] This application belongs to the field of vehicle body technology, specifically relating to an A-pillar structure and a vehicle. Background Technology

[0002] When driving in the rain, rainwater can form water stains on the windows or stagnate behind the windshield triangular cover, affecting the driver's visibility and posing a significant safety hazard. The main reason for this obstruction is that the wipers cause rainwater to overflow at the A-pillar. Specifically, when the vehicle is traveling at high speed, rainwater overflows from the upper part of the A-pillar, with some water accumulating in the side window grooves after crossing the A-pillar, and some overflowing from the grooves and concentrating at the upper part of the side window, thus affecting the driver's visibility.

[0003] To reduce rainwater overflow from the A-pillar and accumulation at the side windows, related technologies incorporate a rain-blocking structure at the A-pillar. This structure allows rainwater to flow downwards, reducing overflow to the side windows and ensuring driving safety in adverse weather conditions.

[0004] Although the aforementioned rain-proof structure can alleviate the problem of rainwater overflowing from the A-pillar, it also obstructs airflow during driving, hindering airflow from conforming to the body. This results in significant wind noise at high speeds, which not only affects passenger comfort but also distracts the driver, causing them to be in a noisy environment for extended periods and thus impacting driving safety. Utility Model Content

[0005] The purpose of this application is to provide an A-pillar structure and vehicle that can simultaneously solve problems such as rainwater overflow and excessive wind noise.

[0006] To solve the above-mentioned technical problems, this application is implemented as follows: In a first aspect, embodiments of this application provide an A-pillar structure, including: an exterior trim panel, a first frame, a second frame, and a sealing element; The second frame is slidably disposed on the first frame along a first direction, which intersects with the extension direction of the A-pillar structure; The outer trim panel is installed on the outside of the first frame and the second frame; The seal is connected to the second frame and moves synchronously with the second frame along the first direction, so that the edge of the seal is retractable relative to the edge of the outer trim panel.

[0007] Based on the above configuration, this embodiment uses a second frame to move the seal relative to the outer trim panel, causing the edge of the seal to expand and contract relative to the edge of the outer trim panel. This allows adjustment of the seal's position. Thus, after the windshield is connected to the A-pillar structure, the seal acts as a seal between the windshield and the A-pillar structure, preventing rainwater and dust from entering. Furthermore, adjusting the relative position of the seal's edge to the edge of the outer trim panel changes the depth of the water channel between the windshield, the seal, and the outer trim panel, adapting to different driving conditions. Therefore, the channel depth can be reduced on non-rainy days to decrease wind noise generated at the water channel during high-speed driving, improving driving comfort and safety. Conversely, the channel depth can be increased on rainy days to increase water flow, effectively mitigating the problem of rainwater overflowing from the A-pillar structure to the side windows and affecting side window visibility, thus improving driving safety.

[0008] In some more specific embodiments, the A-pillar structure also includes a driving component, which can drive the second frame to move relative to the first frame in a first direction, so as to adjust the relative setting between the edge of the second frame and the edge of the outer trim panel by driving the seal to move synchronously through the second frame.

[0009] Optionally, the driving component includes a cooperating fixed component and a movable component; The fixed member is connected to the first frame, and the movable member is connected to the second frame. Therefore, the second frame moves relative to the first frame along a first direction by moving the movable member relative to the fixed member.

[0010] In some more specific embodiments, one of the fixed member and the movable member is a gear and the other is a rack, with the gear and rack meshing together. Based on this, the rotation of the gear and the relative movement of the gear and rack drive the second frame to move relative to the first frame along a first direction, so that the second frame can drive the sealing member to move synchronously, thereby adjusting the relative position between the edge of the sealing member and the edge of the outer trim panel.

[0011] In some more specific embodiments, the second skeleton includes a skeleton body and a connector, and along the first direction, the connector is disposed at the end of the skeleton body opposite to the seal; The gear is rotatably connected to the connector, and the rack is disposed on the first frame.

[0012] In some more specific embodiments, the first frame is provided with a groove extending along the first direction on the side opposite to the outer trim panel, and the connector is slidably connected to the groove. The rack is located on the side wall of the slide groove and meshes with the gear provided on the connector located in the slide groove.

[0013] Based on the above configuration, the sidewall of the slide can restrict the connector to a certain extent, thereby improving the sliding stability of the connector and even the entire second frame.

[0014] In some more specific embodiments, one of the fixed member and the movable member is a fixed rod, and the other is a telescopic rod, with the telescopic rod slidably connected to the fixed rod. Based on this, the second frame moves relative to the first frame in a first direction by sliding the telescopic rod relative to the fixed rod.

[0015] Optionally, the telescopic rod and the fixed rod can be slidably connected by a sleeve. For example, one end of the telescopic rod can be inserted into the fixed rod and move along the axis of the fixed rod; alternatively, one end of the telescopic rod can be sleeved outside the fixed rod and move along the axis of the fixed rod.

[0016] In some more specific embodiments, in the first state, the edge of the sealant is aligned with the edge of the outer trim panel in the first direction. In this state, the sealant can block the edge of the outer trim panel, thereby effectively mitigating the noise generated by wind entering the interior of the edge of the outer trim panel.

[0017] In actual operating conditions, the edges of the exterior trim panel and the windshield are spaced apart, and a seal is located between the exterior trim panel and the windshield. When the edge of the seal is aligned with the edge of the exterior trim panel in the first direction, it can seal the space between the exterior trim panel and the windshield, effectively preventing wind from entering the space between the exterior trim panel and the windshield during high-speed driving and thus preventing noise. Therefore, it can effectively alleviate the noise problem inside the vehicle.

[0018] In some other more specific embodiments, the edge of the seal protrudes beyond the edge of the outer trim panel in the first direction; in this state, the seal can block the edge of the outer trim panel and allow the extra portion protruding beyond the edge of the outer trim panel to cover the windshield, playing a buffering and guiding role, thereby effectively reducing the noise generated by wind entering the interior of the edge of the outer trim panel.

[0019] In actual operation, the edges of the exterior trim panel and the windshield are spaced apart. Part of the seal is located between the exterior trim panel and the windshield, while another part extends beyond the edge of the exterior trim panel. When the edge of the seal protrudes beyond the edge of the exterior trim panel in the first direction, it seals the space between the exterior trim panel and the windshield, and the extra portion protruding from the edge of the exterior trim panel covers the windshield. This buffers and guides the airflow, effectively preventing wind from entering the space between the exterior trim panel and the windshield and generating noise during high-speed vehicle operation. Therefore, it effectively alleviates noise problems inside the vehicle.

[0020] In the second state, the edge of the outer trim panel protrudes beyond the edge of the seal in the first direction. That is, the edge of the seal retracts into the interior of the outer trim panel relative to the edge of the outer trim panel. In this case, a guiding space can be formed on the outer side of the edge of the seal to guide rainwater away. This can effectively prevent rainwater on the windshield from overflowing from the A-pillar structure to the side window and causing limited visibility of the side window, thereby improving driving safety.

[0021] In actual operation, the edges of the exterior trim panel and the windshield are spaced apart, and the edge of the seal is retracted to the inner edge of the exterior trim panel and sealed to the windshield. In this way, the exterior trim panel, the windshield and the seal can form a water channel, which can guide rainwater on the windshield away through the channel, preventing rainwater from overflowing from the A-pillar structure to the side windows and affecting the side window visibility, thus ensuring driving safety.

[0022] In some more specific embodiments, the seal includes a first sealing portion and a second sealing portion; The first sealing part is connected to the second frame and is located on the inner side of the outer trim panel; The second sealing part is disposed at the end of the first sealing part away from the second frame, and the second sealing part extends obliquely in a direction away from the first sealing part and the outer trim panel, so that the extension direction of the second sealing part is set at an obtuse angle to the extension direction of the first sealing part.

[0023] Based on the above configuration, the first sealing part can seal the inside of the exterior trim panel, and the second sealing part can seal the outside of the exterior trim panel. Furthermore, the second sealing part is inclined to facilitate a sealed connection with the windshield and to guide rainwater on the windshield and reduce resistance to rainwater, so as to ensure that rainwater can flow into the water channel along the windshield and the second sealing part.

[0024] In actual working conditions, the first sealing part can be sealed between the exterior trim panel and the windshield to prevent water leakage at the connection between the exterior trim panel and the windshield; the second sealing part can be sealed with the windshield to prevent rainwater from leaking from the windshield and can also guide the rainwater on the windshield.

[0025] Secondly, this application also provides a vehicle, including: a windshield and the aforementioned A-pillar structure; The edge of the windshield extends to the inside of the exterior trim panel; The seal is sealed to the outer surface of the windshield.

[0026] Based on the above configuration, the seal can be used to seal between the windshield and the exterior trim panel to prevent rainwater, dust, and other contaminants from entering the vehicle's cabin. At the same time, by adjusting the position of the seal, the depth of the water channel can be changed to adapt to different driving conditions.

[0027] In some more specific embodiments, in the second state, the edge of the exterior trim panel protrudes beyond the seal in the first direction, so that the inner wall of the exterior trim panel, the seal, and the outer side of the windshield together form a water channel.

[0028] Based on the above configuration, rainwater on the windshield can be diverted away through the water guide channel to prevent rainwater from accumulating on the windshield and affecting the windshield's visibility. In addition, it can also prevent rainwater from overflowing from the A-pillar structure to the side windows and affecting the side window's visibility.

[0029] When driving in non-rainy weather, the second frame moves the seal outward relative to the outer trim panel, aligning the edge of the seal with the edge of the outer trim panel in the first direction, or making the edge of the seal protrude beyond the edge of the outer trim panel, thus eliminating the water channel. This effectively prevents the water channel from increasing wind resistance during driving and helps reduce driving noise.

[0030] When driving in the rain, the second frame moves the seal inward relative to the outer trim panel, causing the edge of the seal to retract relative to the edge of the outer trim panel. This creates a water channel between the outer trim panel, the seal, and the windshield, allowing rainwater on the windshield to be quickly diverted away. This prevents rainwater from overflowing from the A-pillar structure into the side windows and affecting the side window visibility. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0035] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific examples and application scenarios.

[0036] refer to Figures 1 to 4 This application discloses an A-pillar structure 01 for use in vehicles. The disclosed A-pillar structure 01 includes an exterior trim panel 10, a first frame 20, a second frame 30, and a seal 40.

[0037] The first frame 20 is a basic load-bearing component that can provide a load-bearing foundation for components such as the exterior panel 10, the second frame 30, and the seal 40. In some embodiments, the second frame 30 is disposed on the first frame 20 and is slidable relative to the first frame 20 along a first direction, thereby allowing adjustment of the position of the second frame 30 relative to the first frame 20.

[0038] The first direction intersects with the extension direction of the A-pillar structure 01. For example, the A-pillar structure 01 can extend obliquely towards the front and lower direction of the vehicle; the first direction can be the left and right direction of the vehicle.

[0039] The exterior trim panel 10 is installed on the outside of the first frame 20 and the second frame 30. On the one hand, it can provide a certain degree of protection for the first frame 20 and the second frame 30 to prevent them from being affected by external factors such as rain, sunlight, and dust. On the other hand, the exterior trim panel 10 can also serve a decorative purpose, which helps to improve the aesthetics of the A-pillar and the entire vehicle.

[0040] Optionally, the exterior panel 10 can be installed to the first frame 20. For example, the exterior panel 10 can be connected to the first frame 20 by means of snap-fit, screw-fit, welding, riveting, etc., to ensure the installation stability of the exterior panel 10.

[0041] The seal 40 is connected to the second frame 30 and moves synchronously with the second frame 30 along a first direction, so that the edge of the seal 40 is retractable relative to the edge of the outer trim panel 10. Based on this, the seal 40 can be moved synchronously by the movement of the second frame 30 relative to the first frame 20 along the first direction, thereby adjusting the relative position between the edge of the seal 40 and the edge of the outer trim panel 10.

[0042] Optionally, the seal 40 can be a soft rubber part. Additionally, the seal 40 can be connected to the second skeleton 30 via a secondary injection molding process.

[0043] Based on the above configuration, in this embodiment, the second frame 30 drives the seal 40 to move relative to the outer trim panel 10, causing the edge of the seal 40 to expand and contract relative to the edge of the outer trim panel 10. This allows adjustment of the position of the seal 40's edge. Thus, after the windshield 02 is connected to the A-pillar structure 01, the seal 40 provides a seal between the windshield 02 and the A-pillar structure 01, preventing rainwater and dust from entering. Furthermore, adjusting the relative position of the seal 40's edge to the edge of the outer trim panel 10 changes the depth of the water channel M between the windshield 02, the seal 40, and the outer trim panel 10, adapting to different driving conditions. Therefore, the channel depth can be reduced on non-rainy days to decrease wind noise generated at the water channel M during high-speed driving, improving driving comfort and safety. Conversely, the channel depth can be increased on rainy days to increase water flow, effectively mitigating the problem of rainwater overflowing from the A-pillar structure 01 to the side windows and affecting side window visibility, thus improving driving safety.

[0044] In some embodiments, the A-pillar structure 01 may further include a driving component 50, which can drive the second frame 30 to move relative to the first frame 20 in a first direction, so as to adjust the relative setting between the edge of the second frame 30 and the edge of the outer trim panel 10 by driving the seal 40 to move synchronously through the second frame 30.

[0045] Optionally, the drive component 50 includes a fixed member 51 and a movable member 52, and the movable member 52 cooperates with the fixed member 51 so that the movable member 52 can move relative to the fixed member 51.

[0046] The fixed member 51 can be connected to the first frame 20, and the movable member 52 can be connected to the second frame 30. Based on this, the second frame 30 can move relative to the first frame 20 in a first direction by moving the movable member 52 relative to the fixed member 51.

[0047] Of course, in other embodiments, the fixing member 51 can be connected to the first frame 20, and the movable member 52 can be connected to the second frame 30. As long as relative movement between the first frame 20 and the second frame 30 can be achieved, the specific form is not limited.

[0048] In some more specific embodiments, one of the fixed member 51 and the movable member 52 can be a gear and the other can be a rack, with the gear and rack meshing together. Based on this, by rotating the gear and moving the gear and rack relative to each other, the second frame 30 is moved relative to the first frame 20 in a first direction, so that the sealing member 40 can be moved synchronously by the second frame 30 to adjust the relative position between the edge of the sealing member 40 and the edge of the outer trim panel 10.

[0049] For example, the fixed member 51 can be a gear and the movable member 52 can be a rack. In this way, when the gear rotates, it can drive the rack to move in the first direction, and the rack can drive the second frame 30 to move in the first direction. Alternatively, the fixed member 51 can be a rack and the movable member 52 can be a gear. In this way, due to the different fixed members of the rack, the gear can both rotate and move in the first direction on the rack, and the gear can drive the second frame 30 to move in the first direction.

[0050] In some embodiments, the second frame 30 may include a frame body 31 and a connector 32. Along a first direction, the connector 32 is disposed at the end of the frame body 31 opposite to the seal 40. Exemplarily, the seal 40 may be located in the outer end region of the frame body 31, while the connector 32 may be located in the inner end region of the frame body 31. Furthermore, the connector 32 and the frame body 31 may be an integral structure. Alternatively, the connector 32 may be fixedly connected to the frame body 31, such as by welding, riveting, bonding, screwing, or snap-fitting.

[0051] The gear is rotatably connected to the connector 32. Optionally, the connector 32 may be provided with a rotating shaft, and the gear is sleeved on the outside of the rotating shaft, so that the gear can rotate around the rotating shaft relative to the connector 32 to ensure the rotational stability of the gear.

[0052] The rack is mounted on the first frame 20. Optionally, the rack can be fixed to the first frame 20 by means of screwing, welding, snap-fitting, etc., to ensure the installation stability of the rack.

[0053] In order to enable relative movement between the gear and the rack, the drive component 50 may also include a drive element, which may be connected to a gear drive or a rack drive, as long as relative movement between the gear and the rack can be achieved, and the specific form is not limited.

[0054] In some specific embodiments, the driving component can be a motor or electric motor, which can drive the gear to rotate. In other specific embodiments, the driving component can be a linear module, which can drive the rack to move along a first direction.

[0055] In some embodiments, the first frame 20 may be provided with a groove 21 on the side opposite to the outer trim panel 10, the groove 21 extending along a first direction; the connector 32 is slidably connected to the groove 21, so that the side wall of the groove 21 can play a certain limiting role on the connector 32, thereby improving the sliding stability of the connector 32 and even the entire second frame 30.

[0056] The rack is located on the side wall of the slide groove 21, so that the tooth structure of the rack can be set towards the inside of the slide groove 21 and mesh with the gear provided on the connector 32 located in the slide groove 21.

[0057] In other embodiments, one of the fixed member 51 and the movable member 52 can be a fixed rod, and the other can be a telescopic rod, wherein the telescopic rod is slidably connected to the fixed rod. Based on this, the second frame 30 moves relative to the first frame 20 in a first direction by sliding the telescopic rod relative to the fixed rod.

[0058] Optionally, the telescopic rod and the fixed rod can be slidably connected by a sleeve. For example, one end of the telescopic rod can be inserted into the fixed rod and move along the axis of the fixed rod; alternatively, one end of the telescopic rod can be sleeved outside the fixed rod and move along the axis of the fixed rod.

[0059] In some more specific embodiments, the drive component 50 may be in the form of a cylinder, hydraulic cylinder, electric cylinder, etc.

[0060] In some embodiments, in a first state (i.e., a non-rainy state), the edge of the seal 40 can be aligned with the edge of the outer trim panel 10 in a first direction. In this state, the seal 40 can block the edge of the outer trim panel 10, thereby effectively mitigating noise caused by wind entering the interior of the edge of the outer trim panel 10.

[0061] In actual operation, the edge of the exterior trim panel 10 is spaced apart from the edge of the windshield 02, and the seal 40 is located between the exterior trim panel 10 and the windshield 02. When the edge of the seal 40 is aligned with the edge of the exterior trim panel 10 in the first direction, it can seal the space between the exterior trim panel 10 and the windshield 02, thereby effectively preventing wind from entering the space between the exterior trim panel 10 and the windshield 02 and generating noise during high-speed vehicle operation. Therefore, it can effectively alleviate the noise problem inside the vehicle.

[0062] In other embodiments, in a first state, the edge of the seal 40 may protrude beyond the edge of the outer trim panel 10 in a first direction. In this state, the seal 40 can block the edge of the outer trim panel 10, and the extra portion protruding beyond the edge of the outer trim panel 10 covers the windshield 02, acting as a buffer and guide, thereby effectively mitigating noise generated by wind entering the interior of the edge of the outer trim panel 10.

[0063] In actual operation, the edge of the exterior trim panel 10 is spaced apart from the edge of the windshield 02. A portion of the seal 40 is located between the exterior trim panel 10 and the windshield 02, while another portion extends beyond the edge of the exterior trim panel 10. When the edge of the seal 40 protrudes beyond the edge of the exterior trim panel 10 in a first direction, it can seal the space between the exterior trim panel 10 and the windshield 02, and the extra portion protruding from the edge of the exterior trim panel 10 covers the windshield 02. This buffers and guides the airflow, effectively preventing wind from entering the space between the exterior trim panel 10 and the windshield 02 during high-speed vehicle operation and thus preventing noise. Therefore, it effectively alleviates noise problems inside the vehicle.

[0064] In the second state (i.e., the rainy state), the edge of the outer trim panel 10 protrudes beyond the edge of the seal 40 in the first direction. That is, the edge of the seal 40 retracts into the interior of the outer trim panel 10 relative to the edge of the outer trim panel 10. In this case, a guiding space can be formed on the outer side of the edge of the seal 40 so that rainwater can be guided away through the guiding space. This can effectively prevent rainwater on the windshield 02 from overflowing from the A-pillar structure 01 to the side window and causing the side window visibility to be restricted, thereby improving driving safety.

[0065] In actual working conditions, the edge of the exterior trim panel 10 is spaced apart from the edge of the windshield 02, and the edge of the seal 40 is retracted to the inner edge of the exterior trim panel 10 and sealed to the windshield 02. In this way, the exterior trim panel 10, the windshield 02 and the seal 40 can form a water channel M, so that rainwater on the windshield 02 can be diverted away through the channel, preventing rainwater from overflowing from the A-pillar structure 01 to the side window and affecting the side window visibility, thereby ensuring driving safety.

[0066] In some embodiments, the seal 40 may include a first sealing portion 41 and a second sealing portion 42, wherein the first sealing portion 41 is connected to the second sealing portion 42 and is located inside the outer trim panel 10; the second sealing portion 42 is disposed at one end of the first sealing portion 41 away from the second frame 30, and the second sealing portion 42 extends obliquely in a direction away from the first sealing portion 41 and the outer trim panel 10, such that the extension direction of the second sealing portion 42 is set at an obtuse angle to the extension direction of the first sealing portion 41.

[0067] Based on the above configuration, the first sealing part 41 can seal the inner side of the outer trim panel 10, and the second sealing part 42 can seal the outer side of the outer trim panel 10. Furthermore, the second sealing part 42 is inclined to facilitate a sealed connection with the windshield 02, and it also guides the rainwater on the windshield 02 and reduces the resistance to the rainwater, so as to ensure that the rainwater can flow into the water guide groove M along the windshield 02 and the second sealing part 42.

[0068] In actual working conditions, the first sealing part 41 can be sealed between the outer trim panel 10 and the windshield 02 to prevent water leakage at the connection between the outer trim panel 10 and the windshield 02; the second sealing part 42 can be sealed with the windshield 02 to prevent rainwater from leaking from the windshield 02, and can also guide the rainwater on the windshield 02.

[0069] Based on the aforementioned A-pillar structure 01, this application embodiment also discloses a vehicle, which includes a windshield 02 and the aforementioned A-pillar structure 01; wherein, the edge of the windshield 02 extends to the inner side of the exterior trim panel 10, and the sealing member 40 is sealed to the outer side of the windshield 02.

[0070] Based on the above settings, the sealing element 40 can play a sealing role between the windshield 02 and the exterior trim panel 10 to prevent rainwater, dust and other substances from entering the vehicle's cabin from between the windshield 02 and the exterior trim panel 10. At the same time, by adjusting the position of the sealing element 40, the depth of the water channel M can also be changed to adapt to different driving conditions.

[0071] In the second state, the edge of the exterior trim panel 10 protrudes from the seal 40 in the first direction, so that the inner wall of the exterior trim panel 10, the seal 40 and the outer side of the windshield 02 together form a water channel M, so that rainwater on the windshield 02 can be diverted away through the water channel M to prevent rainwater from accumulating on the windshield 02 and affecting the windshield 02's visibility. In addition, it can also prevent rainwater from overflowing from the A-pillar structure 01 to the side window and affecting the side window's visibility.

[0072] In addition, by moving the seal 40 along the first direction through the second frame 30, the relative position of the edge of the seal 40 and the edge of the outer trim panel 10 in the first direction can be changed, thereby realizing the adjustment of the depth of the water guide groove M to adapt to different driving conditions.

[0073] When driving in non-rainy weather, the second frame 30 drives the seal 40 to move outward relative to the outer trim panel 10, so that the edge of the seal 40 is aligned with the edge of the outer trim panel 10 in the first direction, or the edge of the seal 40 protrudes beyond the edge of the outer trim panel 10, so that the water channel M disappears. This can effectively prevent the water channel M from increasing wind resistance during driving and help reduce driving noise.

[0074] When driving in the rain, the second frame 30 drives the seal 40 to move inward relative to the outer trim panel 10, causing the edge of the seal 40 to retract relative to the edge of the outer trim panel 10. This forms a water channel M between the outer trim panel 10, the seal 40, and the windshield 02, allowing rainwater on the windshield 02 to be quickly diverted away through the water channel M, preventing rainwater from overflowing from the A-pillar structure 01 to the side windows and affecting the side window visibility.

[0075] In summary, the embodiments of this application allow the sealing element 40 to be adjusted so that its edge is flush with or protrudes from the edge of the exterior trim panel 10 in non-rainy conditions, so that the edge of the sealing element 40 can effectively receive and guide airflow, thus reducing noise. In rainy conditions, the sealing element 40 can be adjusted so that its edge retracts relative to the edge of the exterior trim panel 10, thereby increasing the depth of the water guide channel M, which guides rainwater flow through the water guide channel M and reduces the amount of rainwater flowing to the side window via the A-pillar structure 01.

[0076] Therefore, the embodiments of this application can not only solve the problem of rainwater overflow affecting the driver's visibility due to side window obstruction, but also improve the noise reduction performance of the vehicle during high-speed driving. According to test drive, at high speeds of 120km / h to 150km / h, the clarity of the voice prompts in the water guide channel M condition and the booster stage are both improved, resulting in a more significant noise reduction effect.

[0077] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
