Description

Technical Field

[0001] This application relates to the field of vehicles, and in particular to a sunroof drain pipe assembly for a vehicle and the vehicle itself. Background Technology

[0002] In related technologies, the sunroof drainage path involves water flowing down the A-pillar through a drain pipe, passing through the air chamber panel sheet metal via the drain pipe sheath, and flowing into the front cabin water channel before being discharged outside the vehicle. However, in this design, the drain pipe sheath outlet faces the front of the vehicle. During high-speed driving in rainy weather, the external airflow impacts the outlet, causing poor water flow and water accumulation. The airflow blowing away this accumulated water creates abnormal noise at the drain pipe sheath outlet, affecting the driving experience. Therefore, eliminating the abnormal noise at the outlet and improving passenger comfort is the technical problem this application aims to solve. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a sunroof drain pipe assembly for vehicles that can eliminate abnormal noise at the water outlet and improve passenger comfort.

[0004] A sunroof drain pipe assembly for a vehicle according to an embodiment of this application includes: a sunroof drain pipe adapted to be installed on the body of a vehicle, the sunroof drain pipe having a water outlet end; a sheath that cooperates with the water outlet end, the sheath having a guide cavity formed therein for guiding liquid flowing out of the water outlet end to the outside; wherein at least a portion of the sheath is directly opposite the water outlet end in the liquid discharge direction of the sunroof drain pipe.

[0005] According to the embodiments of this application, the sunroof drain pipe assembly for vehicles has at least a portion of the sheath directly facing the water outlet end in the liquid outlet direction of the sunroof drain pipe. When external airflow impacts, it first impacts the sheath, which can withstand and disperse the impact force of the airflow, change the flow direction of the airflow, and prevent the airflow from directly rushing towards the water outlet end. This avoids the airflow directly colliding with the water flowing out of the water outlet end, allowing the water to be smoothly discharged under the guidance of the guide cavity in a normal state. This prevents water from accumulating at the water outlet end due to airflow obstruction, further eliminating abnormal noise caused by water accumulation caused by airflow blowing. The noise inside the vehicle is reduced, thereby effectively improving the ride comfort and providing a quieter and more comfortable in-vehicle environment for drivers and passengers.

[0006] According to some embodiments of this application, a sunroof drain pipe assembly for a vehicle includes a sheath comprising: a sheath body fitted around at least a portion of the outer periphery of the sunroof drain pipe; and a guide portion cooperating with the sheath body, wherein the guide portion has a guide cavity formed therein and an opening communicating with the guide cavity is formed on the guide portion to facilitate the outward discharge of liquid, and at least a portion of the guide portion is directly opposite the outlet end of the sunroof drain pipe in the liquid discharge direction.

[0007] According to some embodiments of this application, a sunroof drain pipe assembly for a vehicle includes a flow guide portion comprising: a mating section connected to the sheath body; and a windbreak section connected to the mating section and defining the flow guide cavity, wherein at least a portion of the windbreak section is directly opposite the water outlet end in the liquid outlet direction of the sunroof drain pipe, and the cross-sectional area of ​​the outer end of the windbreak section gradually decreases in the liquid outlet direction.

[0008] According to some embodiments of this application, a sunroof drain pipe assembly for a vehicle has an outer end face of the windbreak section constructed as an arc-shaped surface.

[0009] According to some embodiments of this application, in a sunroof drain pipe assembly for a vehicle, the size of the windbreak section is larger than the size of the outlet of the guide cavity in the projection of the liquid discharge direction.

[0010] According to some embodiments of this application, a sunroof drain pipe assembly for a vehicle includes a windbreak section comprising: a first section, the first section being cylindrical and connected to the mating section; and a second section, one end of the second section being connected to the first section and having an outer diameter that gradually increases in a direction away from the first section, the second section having the flow guide cavity formed therein, and the end of the second section having a cover facing the water outlet.

[0011] According to some embodiments of this application, a sunroof drain pipe assembly for a vehicle has a second section having an opening that opens radially upwards and connects to the drainage cavity.

[0012] According to some embodiments of this application, a sunroof drain pipe assembly for a vehicle is provided with a limiting protrusion on the sheath body and a corresponding mating groove on the guide portion. The limiting protrusion and the mating groove cooperate with each other to restrict the rotation of the guide portion on the sheath body.

[0013] According to some embodiments of this application, a sunroof drain pipe assembly for a vehicle has an annular snap-fit ​​portion on the outer periphery of the sheath, the annular snap-fit ​​portion being connected to the vehicle body, and the annular snap-fit ​​portion being adapted to limit the displacement of the sheath.

[0014] The vehicle according to an embodiment of this application is briefly described below.

Since the vehicle according to this embodiment is equipped with the sunroof drain pipe assembly of any of the above embodiments, at least a portion of the sheath in the vehicle according to this application is directly opposite the water outlet end in the liquid outlet direction of the sunroof drain pipe. This can effectively block the external airflow from directly impacting the water outlet end, eliminate the abnormal noise caused by the airflow blowing the stored water, create a quiet environment in the vehicle, and improve the comfort of the driver and passengers during the driving process. At the same time, due to the smooth drainage, the risk of failure caused by microbial growth, blockage, and other problems in the drainage system is reduced, ensuring that the sunroof drainage system can operate stably for a long time and reducing the frequency of vehicle maintenance due to drainage system failure.

[0033] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0034] The following is for reference. Figures 1-5 This application describes a sunroof drain pipe assembly 100 for a vehicle and a vehicle according to embodiments thereof.

[0035] According to an embodiment of this application, a sunroof drain pipe assembly 100 for a vehicle includes a sunroof drain pipe 1 and a sheath 2. The sunroof drain pipe 1 is adapted to be installed on the vehicle body 3. The sunroof drain pipe 1 is provided with a water outlet 11. The sheath 2 cooperates with the water outlet 11. A guide cavity 21 is formed inside the sheath 2 to guide the liquid flowing out of the water outlet 11 to the outside. At least a portion of the sheath 2 is directly opposite the water outlet 11 in the liquid outlet direction of the sunroof drain pipe 1.

[0036] In the vehicle sunroof drain pipe assembly 100 of this application embodiment, at least a portion of the sleeve 2 is directly opposite the water outlet 11 in the liquid outlet direction of the sunroof drain pipe 1. The external airflow will first come into contact with the sleeve 2 on the path of impacting the water outlet 11. Due to the obstruction of the sleeve 2 in the liquid outlet direction, the airflow cannot directly impact the water outlet 11 and the water flow at the water outlet 11. Since at least a portion of the sleeve 2 is directly opposite the water outlet 11, it bears and disperses the impact force of the airflow, causing the airflow to change its flow direction. The airflow bypasses the sleeve 2 or flows along the surface of the sleeve 2, thereby weakening the interference of the airflow on the water flow at the water outlet 11. In this case, the water flow at the water outlet 11 can flow out stably under the guidance of the guide cavity 21, and will not accumulate water at the water outlet 11 due to the strong obstruction of the airflow. This avoids the abnormal noise caused by the airflow blowing the accumulated water, so that the in-vehicle environment can be kept quiet and the driver and passengers will not be disturbed by abnormal noise, thereby effectively improving the comfort of riding and significantly improving the driving experience.

[0037] Meanwhile, since at least a portion of the sheath 2 is directly opposite the water outlet 11 in the liquid outlet direction of the sunroof drain pipe 1, water accumulation at the water outlet 11 is avoided, ensuring the stability of the drainage system. The guide cavity 21 can stably guide the water flow out, avoiding the accumulation of debris in the water at the water outlet 11 due to water accumulation, which would lead to blockage of the water outlet 11 and poor drainage of the drainage system. This reduces the maintenance needs of the vehicle's drainage system, saves time and effort spent on maintenance, and improves customer convenience and satisfaction.

[0038] It should be noted that at least a portion of the sheath 2 is directly opposite the water outlet 11 in the liquid discharge direction of the sunroof drain pipe 1. This means that in the projection of the sheath 2 in the liquid discharge direction of the sunroof drain pipe 1, at least a portion of the projection of the sheath 2 coincides with the projection of the water outlet 11, so that the sheath 2 can serve to withstand and disperse the impact force caused by the airflow on the water outlet 11.

[0039] In some embodiments of this application, the upper end of the sunroof drain pipe 1 is located at the upper end of the A-pillar for collecting liquid within the sunroof area. The other end of the sunroof drain pipe 1 can pass through the body panel to drain the liquid within the sunroof area. At least a portion of the sunroof drain pipe 1 can be attached to the A-pillar and located on the outside of the A-pillar, or it can be located in the cavity enclosed by the A-pillar or the vehicle sheet metal parts.

[0040] According to some embodiments of this application, a sunroof drain pipe assembly 100 for a vehicle includes a sheath 2 comprising a sheath body 22 and a guide portion 23. The sheath body 22 is sleeved on at least a portion of the outer periphery of the sunroof drain pipe 1. The guide portion 23 cooperates with the sheath body 22. A guide cavity 21 is formed in the guide portion 23, and an opening 233 communicating with the guide cavity 21 is formed on the guide portion 23 to facilitate the outward discharge of liquid. At least a portion of the guide portion 23 is directly opposite the water outlet end 11 in the liquid discharge direction of the sunroof drain pipe 1.

[0041] The sheath body 22 is fitted onto at least part of the outer periphery of the sunroof drain pipe 1, serving as a preliminary protection for the sunroof drain pipe 1 and a positioning function for the subsequent installation of the guide section 23. The sheath body 22 can provide an installation foundation for the subsequent installation of the guide section 23 on the sunroof drain pipe 1.

[0042] Furthermore, the guide section 23 cooperates with the sheath body 22, and the guide cavity 21 formed by the guide section 23 provides a channel for the water flow. When the water flows into the guide cavity 21 from the outlet of the sunroof drain pipe 1, it flows out through the guide cavity 21 and forms an opening 233 on the guide section 23 that communicates with the guide cavity 21. In particular, at least a portion of the guide section 23 is directly opposite the water outlet 11 in the liquid discharge direction of the sunroof drain pipe 1. In related technologies, when the vehicle is traveling at high speed, the external airflow will impact the water outlet 11, causing the water flow to be resisted and unable to be discharged smoothly, resulting in problems such as water accumulation at the water outlet 11 and abnormal noise. When a portion of the guide section 23 is directly opposite the water outlet 11, the high-speed airflow first impacts the resistance of the guide section 23. In the deflector section, the airflow changes direction along the surface of the guide section 23, being dispersed and guided, thereby reducing the direct impact force on the water flow through the opening 233. The water flow can then smoothly exit the vehicle through the opening 233 with relatively little airflow interference, preventing water accumulation at the outlet 11 and eliminating abnormal noises caused by water being blown by the airflow. This significantly improves the quietness and comfort inside the vehicle, while also ensuring the reliability and stability of the sunroof drainage system under various driving conditions. It reduces the potential risks of moisture damage to internal vehicle components caused by poor drainage, extends the service life of related vehicle components, and reduces vehicle maintenance costs and frequency, providing users with a better user experience and higher vehicle performance assurance.

[0043] In some embodiments of this application, the sheath body 22 and the flow guide 23 are snap-fit ​​connected. One of the outer wall of the sheath body 22 and the interior of the flow guide 23 is provided with a plurality of protrusions 223. The protrusions 223 are inclined upward toward the axial direction of the sheath body 22. The other of the outer wall of the sheath body 22 and the interior of the flow guide 23 is provided with a groove 235 that cooperates with the protrusions 223. This can prevent the flow guide 23 from slipping off the sheath body 22 and improve the connection strength between the sheath body 22 and the flow guide 23.

[0044] According to some embodiments of this application, a sunroof drain pipe assembly 100 for a vehicle includes a flow guide 23 comprising a mating section 231 and a windbreak section 232. The mating section 231 is connected to the sheath body 22, and the windbreak section 232 is connected to the mating section 231 and defines a flow guide cavity 21. At least a portion of the windbreak section 232 is directly opposite the water outlet end 11 in the liquid outlet direction of the sunroof drain pipe 1, and the cross-sectional area of ​​the outer end of the windbreak section 232 gradually decreases in the liquid outlet direction.

[0045] The connecting section 231 is connected to the sheath body 22, so that the guide section 23 and the sheath body 22 are combined into an integral drainage structure, which ensures that the water flowing out of the skylight drain pipe 1 can be smoothly guided into the guide cavity 21 defined by the windbreak section 232 and the connecting section 231, avoiding leakage or turbulence of water flow during the transition process, and laying the foundation for the orderly discharge of subsequent water flow.

[0046] At least a portion of the windshield section 232 is directly opposite the water outlet 11 in the liquid discharge direction of the sunroof drain pipe 1. When the vehicle is traveling at high speed, the airflow cannot directly impact the water flow at the water outlet 11 due to the obstruction of the windshield section 232. The windshield section 232 bears and disperses the impact force of the airflow, forcing the airflow to flow along the surface of the windshield section 232 and change direction, effectively protecting the normal discharge of water at the water outlet 11 and avoiding abnormal noise, poor water flow, and water retention caused by direct airflow impact. The outer end of the windshield section 232 has a structure with a gradually decreasing cross-sectional area in the liquid discharge direction. When the airflow flows along the surface of the windshield section 232 to the outer end, the change in cross-sectional area will create a local pressure reduction zone, further promoting the airflow to quickly pass around the windshield section 232 without forming backflow or vortex at the outlet, thereby further reducing the adverse effects on the drainage water flow.

[0047] According to some embodiments of this application, the outer end face of the windshield section 232 of the sunroof drain pipe assembly 100 for a vehicle is constructed as an arc-shaped surface.

[0048] During high-speed vehicle operation, when airflow impacts the arc-shaped outer end face of the windshield section 232, the arc shape effectively disperses the impact force of the airflow. This avoids the problem of airflow being segmented without weakening due to the presence of corners on a flat end face, which could potentially continue to impact other parts of the vehicle's drain pipe and affect drainage performance. When airflow hits the arc-shaped surface, there is no concentrated airflow reflection; the airflow gradually disperses along the curvature of the arc-shaped surface, allowing the energy of the airflow to be dispersed over a larger area. This reduces the impact interference of the airflow on the water flow at the outlet 11, ensuring that the water flow is discharged in a relatively stable environment. This avoids problems such as poor water flow, water retention, and abnormal noise caused by airflow impact. The arc-shaped outer end face of the windshield section 232 helps maintain the relative stability of the surrounding airflow environment during vehicle operation, avoiding additional resistance or noise caused by turbulent airflow near the outlet 11, further improving the vehicle's driving comfort and the reliability of the drainage system.

[0049] According to some embodiments of this application, in the projection of the sunroof drain pipe assembly 100 for a vehicle, the size of the windshield section 232 is larger than the size of the outlet of the guide cavity 21 in the direction of liquid discharge.

[0050] Because the size of the windshield section 232 is larger than the outlet size of the guide cavity 21 in the projection of the liquid outlet direction, it means that the windshield section 232 can provide a wider shielding range in the liquid outlet direction. When the airflow impacts, the windshield section 232 can more comprehensively block the front of the outlet of the guide cavity 21, ensuring that the airflow cannot directly impact the water flow at the outlet of the guide cavity 21. Even if the airflow has a certain angular deviation or diffusion, the larger size of the windshield section 232 can intercept it with a high probability, thereby creating a relatively stable discharge environment for the water flow that is not directly affected by the airflow. This ensures that the water flow can be smoothly discharged outside the vehicle along the normal path, avoiding insufficient protection that could cause the water flow discharge path to be twisted or interrupted by the airflow impact, resulting in poor drainage and water accumulation. The larger size of the windshield section 232, in its projection relative to the outlet of the guide cavity 21, can better maintain the stability of the water flow discharge path, reducing various drainage problems that may be caused by path instability, and further ensuring the normal operation of the sunroof drainage system.

[0051] According to some embodiments of this application, a sunroof drain pipe assembly 100 for a vehicle includes a windbreak section 232 comprising a first section 2321 and a second section 2322. The first section 2321 is cylindrical and connected to a mating section 231. One end of the second section 2322 is connected to the first section 2321 and its outer diameter gradually increases in the direction away from the first section 2321. A flow guide cavity 21 is formed in the second section 2322 and a cover 2323 is formed at the end of the second section 2322 that is directly opposite to the water outlet 11.

[0052] When the water flows out of the skylight drain pipe 1, it first enters the area defined by the first section 2321 of the windbreak section 232 and the cooperating section 231. The cylindrical structure of the first section 2321 provides a relatively regular and stable transition space for the water flow. The water flow can maintain a relatively orderly flow state in this space, avoiding the sudden diffusion or turbulence that may occur when the water flows directly into the guide cavity 21 from the drain pipe.

[0053] One end of the second segment 2322 is connected to the first segment 2321, and its outer diameter gradually increases in the direction away from the first segment 2321. When the vehicle is traveling at high speed, the gradually increasing outer diameter of the second segment 2322 provides a wider blocking area when the airflow rushes towards the water outlet 11 area of ​​the sunroof drain pipe assembly 100. This allows it to more effectively intercept airflow from different angles, ensuring that the airflow cannot directly impact the water flow at the outlet of the guide cavity 21. As the outer diameter increases, after the airflow hits the surface of the second segment 2322, it will change its flow direction along its gradually increasing outer surface and be effectively guided to the surroundings. The guiding effect allows the airflow to bypass the water outlet 11 area of ​​the sunroof drain pipe assembly 100 more smoothly, rather than forming turbulent airflow vortices or backflows near the water outlet 11. This further reduces the adverse effects of the airflow on the water flow and ensures that the water flow can be discharged outside the vehicle in a relatively stable airflow environment.

[0054] According to some embodiments of this application, a sunroof drain pipe assembly 100 for a vehicle has a radially upward-opening opening 233 formed on the second segment 2322, which connects to the guide cavity 21.

[0055] An open opening 233 is provided radially on the second segment 2322. The opening 233 connects to the guide cavity 21, providing a flow path for the water flow and guiding the water in the guide cavity 21 to the outside, thereby realizing the discharge of the water flow. This avoids the noise caused by the axial opening 233 colliding with the airflow due to the axial opening 233. In some embodiments of this application, the radially open opening 233 is oriented downward along the height direction of the vehicle. The water flow will be discharged to the lowest position of the opening 233 under the action of gravity, avoiding water accumulation.

[0056] Meanwhile, when the vehicle is traveling at high speed, the external airflow rushes towards the second section 2322. Since the opening 233 is open radially upward, after the airflow hits the surface of the second section 2322, some of the airflow will enter the interior of the opening 233 along the edge of the opening 233, creating a pressure difference at the opening 233. This can accelerate the water flow from the guide cavity 21. It can be understood that at the opening 233, the external airflow velocity is high, while the airflow velocity inside the guide cavity 21 is slow. Where the fluid velocity is high, the pressure is low. Therefore, a relatively low air pressure will be formed outside the opening 233, while the interior of the guide cavity 21 is a high-pressure area relative to the opening 233. The pressure difference will cause the water in the guide cavity 21 to be drawn out by the pressure, achieving the effect of accelerating drainage, improving the drainage speed and efficiency, and also realizing the self-cleaning function of the guide cavity 21 by expelling the debris.

[0057] In some embodiments of this application, the edge of the opening 233 near the end of the second segment 2322 is inclined toward the end of the second segment 2322, which not only retains the guiding function of the second segment 2322, but also avoids the accumulation of sand and foreign objects in the arc area on the edge of the opening 233, forming debris accumulation and affecting the guiding effect.

[0058] According to some embodiments of this application, a sunroof drain pipe assembly 100 for a vehicle has a limiting protrusion 221 on the sheath body 22 and a corresponding mating groove 234 on the guide portion 23. The limiting protrusion 221 and the mating groove 234 cooperate with each other to limit the rotation of the guide portion 23 on the sheath body 22.

[0059] During vehicle operation, bumps, vibrations, and various changes in driving posture occur. When the guide section 23 engages with the sheath body 22 via the limiting protrusion 221 and the mating groove 234, restricting the rotation of the guide section 23 on the sheath body 22, it ensures that the position and angle of the guide section 23 relative to the sheath body 22 remain fixed. This also fixes the position and angle of the guide cavity 21, which is jointly defined by the guide section 23 and the sheath body 22. This prevents the guide section 23 from rotating arbitrarily during bumps and vibrations, which could cause changes in the angle of the guide cavity 21, further altering the orientation of the opening 233. This could lead to an obstructed flow path for water within the guide cavity 21, potentially causing leakage or backflow, thus affecting drainage efficiency. The limiting engagement ensures the stability of the guide cavity 21, allowing water to flow orderly along a predetermined path within the guide cavity 21, thereby guaranteeing the normal operation of the drainage system.

[0060] According to some embodiments of this application, a sunroof drain pipe assembly 100 for a vehicle has an annular snap-fit ​​portion 222 provided on the outer periphery of the sheath 2. The annular snap-fit ​​portion 222 is connected to the vehicle body 3 and is adapted to limit the displacement of the sheath 2.

[0061] Furthermore, an annular snap-fit ​​part 222 is provided on the outer periphery of the cover 2. The annular snap-fit ​​part 222 is connected to the vehicle body 3. The displacement of the cover 2 is restricted by the annular snap-fit ​​part 222. No matter how the vehicle vibrates or shakes, the cover 2 can remain in a relatively fixed position, thereby ensuring the stability of the entire drainage path. This allows the water flow to always follow the predetermined path, smoothly discharged from the sunroof drain pipe 1 through the guide cavity 21 and other structures of the cover 2, ensuring the normal operation of the sunroof drainage system under various driving conditions.

[0062] In some embodiments of this application, the sheath body 22 and the guide portion 23 are integrally formed.

[0063] The vehicle according to an embodiment of this application is briefly described below.

This can effectively block the external airflow from directly impacting the water outlet 11, eliminate the abnormal noise caused by the water being blown by the airflow, create a quiet environment in the vehicle, and improve the comfort of the driver and passengers during the driving process. At the same time, due to the smooth drainage, the risk of failure caused by microbial growth, blockage, and other problems in the drainage system is reduced, ensuring that the sunroof drainage system can operate stably for a long time and reducing the frequency of vehicle maintenance due to drainage system failure.
