Abstract
Description
Technical Field
[0001] This application relates to the field of vehicle technology, and more particularly to a water guiding device and a vehicle. Background Technology
[0002] During vehicle operation, the engine compartment is prone to producing odorous gases due to its high-temperature working environment. At the same time, rainwater, car wash water, or snow melt water will collect in the compartment through the drainage channel below the windshield. To prevent water accumulation from causing corrosion of electrical components or dampness inside the compartment, the bottom of the drainage channel is usually equipped with a drain outlet, through which the liquid is drained out of the vehicle via a water pipe.
[0003] However, the existing drainage structure has poor sealing performance. When not draining, odorous and hot air in the engine compartment can seep back into the vehicle's air conditioning external circulation intake through the water guide pipe in the drainage structure, thereby polluting the air inside the vehicle. Utility Model Content
[0004] In view of this, this application provides a water guiding device and vehicle, which helps to block the backflow of odorous hot air generated in the engine compartment into the air conditioning system and avoid polluting the air inside the vehicle.
[0005] To achieve the above objectives, the technical solution of this application is implemented as follows:
[0006] In a first aspect, this application provides a water guiding device for an engine compartment of a vehicle, the engine compartment having a water channel with a drain outlet on the bottom wall of the water channel, the water guiding device comprising: a water guiding pipe, the first end of the water guiding pipe being connected to the drain outlet; and an end cap assembly comprising an end cap seat and an end cap plate, the end cap seat being fixed to the second end of the water guiding pipe, the end cap seat having a water outlet, and the end cap plate being configured to close the water outlet under gravity and open the water outlet under water pressure within the water guiding pipe.
[0007] According to the water guiding device provided in the embodiments of this application, the water outlet is closed by the gravity adaptive sealing mechanism of the end cover assembly when there is no drainage demand, effectively preventing the odor and heat from the engine compartment from seeping back into the air conditioning external circulation system through the water guiding pipe; when there is a drainage demand, the water flow pressure can push open the end cover to open the water outlet, ensuring that the accumulated water is discharged quickly, thus taking into account both drainage efficiency and dynamic sealing. This avoids the risk of corrosion of electrical components in the engine compartment caused by water accumulation and improves the air quality inside the vehicle. At the same time, the water guiding device has a simple and reliable structure, does not require an additional control unit, and reduces maintenance costs and failure rate.
[0008] In one possible implementation, the end face of the outlet is inclined relative to a reference surface, and the reference surface is perpendicular to the central axis of the outlet.
[0009] In this way, by tilting the end face of the outlet relative to the reference plane perpendicular to the central axis, the end cover can form a tighter fit with the tilted end face of the outlet when it closes under gravity, effectively reducing the sealing gap and enhancing the static sealing performance.
[0010] In one possible implementation, the angle between the end face of the outlet and the reference surface is 8°-30°.
[0011] In this way, by limiting the angle between the end face of the outlet and the reference surface to 8°-30°, it ensures that the end cover plate fully fits the inclined end face when closed by gravity, increasing the contact area to improve static sealing performance and effectively preventing trace leakage of odor gases. Furthermore, by optimizing the inclination angle to match the water flow impact direction, the water flow pressure is concentrated on the opening direction of the end cover plate, reducing the critical water pressure threshold for opening and closing the end cover plate, thus enabling a rapid response to drainage needs even when there is low flow of water accumulation.
[0012] In one possible implementation, the top end of the end cover plate is hinged to the end cover seat, and the bottom end of the end cover plate is separable from the end cover seat.
[0013] Thus, by hinged top of end cover plate to end cover seat and adopting a separable fit design at bottom of end cover plate, stable guidance for opening and closing of end cover plate can be achieved: the hinged structure ensures that end cover plate maintains precise alignment when closed by gravity, avoiding sealing failure caused by misalignment, while limiting its opening and closing trajectory to prevent excessive overturning or jamming under water flow impact; the separable design at bottom of end cover plate ensures that water flow pressure is concentrated at bottom contact surface, pushing end cover plate open with less resistance, improving drainage response sensitivity, and quickly resetting to a fully closed state by gravity and hinge constraint when there is no water pressure, enhancing the dynamic drainage efficiency and static sealing performance of end cover plate.
[0014] In one possible implementation, one of the end cover plate and the end cover seat is provided with a pivot shaft, and the other is provided with a pivot groove, wherein the pivot shaft is rotatably disposed in the pivot groove.
[0015] Thus, the coordinated design of the pivot shaft and pivot groove achieves stable guidance and low-friction movement of the end cover plate, ensuring that the end cover plate always moves along a fixed trajectory during opening and closing. In addition, the separate design of the pivot shaft and pivot groove simplifies the assembly process and facilitates the cleaning of accumulated impurities, improving the environmental adaptability and reliability of the water guiding device.
[0016] In one possible implementation, the water guiding device further includes a counterweight disposed on the end cover plate to increase the gravity on the end cover plate.
[0017] Thus, by adding counterweights, the self-sealing capability of the end cover plate under static conditions can be enhanced, ensuring a tight fit with the outlet to improve sealing. Simultaneously, the split counterweight design allows for flexible adjustment of the counterweight to adapt to the drainage pressure requirements of different vehicle models. Furthermore, the inertia of the counterweights can suppress unexpected shaking of the end cover plate caused by vehicle bumps or vibrations, further ensuring sealing stability under complex operating conditions.
[0018] In one possible implementation, the counterweight comprises a metal component.
[0019] In this way, by using metal counterweights, their high density characteristics can be fully utilized to increase the self-closing gravity of the end cover within a limited volume, ensuring that the valve closes tightly when there is no water flow, and effectively resisting unexpected opening caused by air pressure fluctuations or vibrations in the engine compartment.
[0020] In one possible implementation, the water guiding device further includes a shock-absorbing pad disposed on at least one of the outlet end face of the end cover plate and the end cover seat.
[0021] Thus, by setting up shock-absorbing pads, their elastic deformation characteristics can be used to compensate for the microscopic unevenness between the sealing surfaces of the end cover plate and the end cover seat, improve the contact fit when the end cover plate is closed, effectively eliminate sealing gaps caused by vibration or processing tolerances, and enhance the ability to block odors and hot air.
[0022] In one possible implementation, the shock-absorbing pad comprises a plastic component.
[0023] In this way, the elastic damping effect of the plastic parts can absorb the vibration energy caused by vehicle bumps or water flow impact, reduce rigid collisions and noise between metal parts, avoid deformation or wear of the end cover plate due to long-term vibration, and extend the service life of the water guiding device.
[0024] Secondly, this application also provides a vehicle, including the aforementioned water guiding device.
[0025] The vehicle provided in this application, by adopting the aforementioned water guiding device, can dynamically isolate odors and heat from the engine compartment using its self-sealing structure. When there is no drainage, the outlet remains closed, effectively preventing odors from seeping back into the air conditioning external circulation system through the water guiding pipe, significantly improving the cleanliness of the air inside the vehicle. When draining water, the water pressure automatically opens the valve to ensure that rainwater, car wash liquid, etc. are quickly discharged, avoiding water accumulation that could cause corrosion or electrical failures in the engine compartment. At the same time, the purely mechanical design does not rely on electronic control units, adapting to complex operating conditions such as high temperatures and vibrations in the engine compartment, balancing long-term sealing stability and low maintenance costs, and comprehensively improving the vehicle's environmental adaptability and driving health experience.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.

Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.
[0038] In existing technology, rainwater, car wash water, or snow melt water collects in the cabin through a drainage channel below the windshield. To prevent water accumulation from corroding electrical components or causing dampness inside the cabin, the drainage channel usually has a drain outlet at the bottom, through which the liquid is drained outside the vehicle via a guide pipe. Furthermore, the external air circulation intake of the car's air conditioning system is typically located at the front of the engine compartment (such as below the windshield wipers), adjacent to the drainage channel area. However, existing drainage structures have poor sealing performance. When not draining, odorous and hot air from the engine compartment can seep back into the vehicle's external air circulation intake through the guide pipe in the drainage structure, thus polluting the air inside the vehicle.
[0039] In view of this, the present application provides a water guiding device and a vehicle. Through the gravity adaptive sealing mechanism of the end cover assembly, the water outlet is closed by the gravity of the end cover plate when there is no drainage need, effectively preventing the odor and heat from the engine compartment from seeping back into the air conditioning external circulation system through the water guiding pipe. When there is a drainage need, the water flow pressure can push open the end cover plate to open the water outlet, ensuring that the accumulated water is discharged quickly. This balances drainage efficiency and dynamic sealing, avoiding the risk of corrosion of electrical components in the engine compartment caused by water retention, and improving the air quality inside the vehicle. At the same time, the water guiding device has a simple and reliable structure, requires no additional control unit, and reduces maintenance costs and failure rate.
[0040] It should be noted that the vehicle in this application can refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, a bus, a truck, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. For instance, the vehicle can be any one of electric vehicles / electric cars, pure electric vehicles, hybrid electric vehicles, range-extended electric vehicles, plug-in hybrid electric vehicles, and new energy vehicles.
[0041] Vehicles typically consist of wheels, a power source, and a transmission system between the wheels and the power source. The transmission system transmits the power provided by the power source to the wheels, causing them to rotate and thus driving the vehicle.
[0042] It should be noted that the type of power source of the vehicle is not limited in the embodiments of this application. For example, for fuel vehicles, the power source can refer to fuel engines such as gasoline engines and diesel engines; for electric vehicles, the power source can refer to electric motors; for hybrid vehicles, the power source can refer to engines or electric motors; for vehicles powered by other means, the power source can refer to devices that generate power.
[0043] The vehicle may also include a chassis and a body mounted on the chassis. The body may have a passenger compartment, which may include a driver's seat, passenger seats, etc., where the driver can operate the vehicle. For example, the vehicle body may also include structural components such as a steering wheel, clutch, and brakes to enable the vehicle to perform its full functions; this application does not impose any limitations on these components.
[0044] The following is for reference. Figure 1 , Figure 2 , Figure 3 This application provides a water guiding device 1 for use in the engine compartment of a vehicle. The engine compartment has a water channel 2, and the bottom wall of the water channel 2 has a drain outlet 20. The water guiding device 1 is located at the drain outlet 20. The water channel 2 can be used to collect external liquids such as rainwater, car wash water, or snow melt water, preventing them from flowing into the engine compartment and avoiding water accumulation that could corrode electrical components or cause dampness. The drain outlet 20 can be located at the lowest point or side of the bottom wall of the water channel 2, serving as a channel outlet for liquid discharge, guiding the liquid collected in the water channel 2 to the water guiding device 1, ensuring that accumulated water can be discharged outside the vehicle.
[0045] Further, the water guiding device 1 includes a water guiding pipe 11 and an end cap assembly 12. A first end of the water guiding pipe 11 can be connected to a drain outlet 20. A second end of the water guiding pipe 11 can be connected to the end cap assembly 12. Specifically, the end cap assembly 12 includes an end cap seat 121 and an end cap plate 122. The end cap seat 121 has a water outlet 1211. The second end of the water guiding pipe 11 can be fixedly connected to the end cap seat 121. The end cap plate 122 can be movably connected to the end cap seat 121. The end cap plate 122 is configured to close the water outlet 1211 under gravity and open the water outlet 1211 under water pressure within the water guiding pipe 11.
[0046] Optionally, the water pipe 11 may be equipped with a flexible heating layer (such as an electric heating tape or thermally conductive silicone). Alternatively, an elastic antifreeze sealing ring may be added between the end cover plate 122 and the end cover seat 121 to prevent freezing and adhesion that could prevent the end cover plate 122 from opening and closing properly, ensuring stable drainage function in winter. In addition, a miniature pressure sensor or displacement detection module may be integrated into the end cover seat 121 to provide feedback on the opening and closing status of the end cover plate 122 or drainage abnormalities (such as blockage alarms) to the vehicle system via wireless signals (such as Bluetooth).
[0047] Understandably, through the gravity adaptive sealing mechanism of the end cover assembly 12, the water outlet 1211 is closed by the gravity of the end cover plate 122 when there is no need for drainage, effectively preventing the odor and heat from the engine compartment from seeping back into the air conditioning external circulation system through the water guide pipe 11; when there is a need for drainage, the water flow pressure can push open the end cover plate 122 to open the water outlet 1211, ensuring that the accumulated water is discharged quickly, thus taking into account both drainage efficiency and dynamic sealing. This avoids the risk of corrosion of electrical components in the engine compartment caused by water retention, and also improves the air quality inside the vehicle. At the same time, the water guide device 1 has a simple and reliable structure, does not require an additional control unit, and reduces maintenance costs and failure rate.
[0048] In one possible implementation, refer to Figure 1 , Figure 2 , Figure 3 The end face of the outlet 1211 can be inclined. Specifically, the end face of the outlet 1211 can be inclined relative to a reference surface. The reference surface can refer to a plane perpendicular to the central axis of the outlet 1211.
[0049] It is understandable that by tilting the end face of the outlet 1211 relative to the reference plane perpendicular to the central axis, the end cover plate 122 can form a tighter fit with the tilted end face of the outlet 1211 when it closes under the action of gravity, effectively reducing the sealing gap and enhancing the static sealing performance.
[0050] In one possible implementation, refer to Figure 3The angle between the end face of the outlet 1211 and the reference plane can be 8°-30°. The reference plane can be a vertical plane. Optionally, the angle between the end face of the outlet 1211 and the reference plane can be 8°, 10°, 12°, 14°, 16°, 18°, 20°, 22°, 24°, 26°, 28°, or 30°. The angle between the end face of the outlet 1211 and the reference plane can be determined according to actual needs, and this application does not impose any restrictions.
[0051] By setting the angle between the end face of the outlet 1211 and the reference surface between 8° and 30°, it avoids a small inclination angle that would reduce the contact area between the end cover plate 122 and the end face of the outlet 1211, weakening the gravity pressure distribution effect. This would make it easier for micro-gaps to form due to vibration or air pressure fluctuations during closure, leading to leakage of odorous gases. Furthermore, at a low inclination angle, the angle between the water flow impact direction and the opening / closing direction of the end cover plate 122 is too large, requiring higher water pressure to open the end cover plate 122. This could easily lead to low-flow water accumulation that cannot be discharged in time, causing a risk of stagnation. In addition, it also avoids an excessively large inclination angle that would result in insufficient closing pressure of the end cover plate 122, reducing the sealing tightness. Moreover, a high inclination angle would cause some water flow energy to be reflected and dissipated by the inclined surface, reducing drainage efficiency. In extreme cases, this could potentially cause turbulence or localized negative pressure within the water guide pipe 11.
[0052] Understandably, by limiting the angle between the end face of the outlet 1211 and the reference surface to 8°-30°, it ensures that the end cover 122 is fully fitted with the inclined end face when closed by gravity, increasing the contact area to improve static sealing performance and effectively preventing trace leakage of odorous gases. Furthermore, by optimizing the inclination angle to match the water flow impact direction, the water flow pressure is concentrated on the opening direction of the end cover 122, reducing the critical water pressure threshold for opening and closing the end cover 122, thus enabling it to quickly respond to drainage needs even when there is low flow of water accumulation.
[0053] In one possible implementation, refer to Figure 1 , Figure 2 , Figure 3 The end cover plate 122 can be hinged to the end cover seat 121. Furthermore, the top end of the end cover plate 122 can be hinged to the end cover seat 121. In addition, the bottom end of the end cover plate 122 can be separably fitted with the end cover seat 121 to realize the opening and closing function of the end cover plate 122 on the outlet 1211.
[0054] Optionally, a double pivot shaft 123 or a sliding hinge can be provided at the top of the end cover plate 122. The pivot shaft 123 is located in the pivot groove 124 to distribute stress concentration during the opening and closing process, avoid deformation or wear of the single-axis hinge due to long-term use, and limit the maximum opening angle of the end cover plate 122 (e.g., 30°) to prevent excessive overturning under water flow impact. Optionally, the hinge point between the end cover plate 122 and the end cover seat 121 can also be located on the side of the end cover plate 122 (e.g., the left or right side), so that the end cover plate 122 can rotate and open and close around the lateral axis, thus being suitable for installation scenarios with limited vertical space and avoiding interference with surrounding components. Optionally, an arc-shaped flow guide protrusion can also be designed on the inner side of the bottom end of the end cover plate 122 to guide the fluid to concentrate on the bottom end of the end cover plate 122 when water flow impacts, thereby accelerating valve opening and reducing the risk of impurities getting stuck.
[0055] Understandably, by hinged to the top of the end cover plate 122 and the end cover seat 121, and by adopting a separable fit design at the bottom of the end cover plate 122, stable guidance for the opening and closing of the end cover plate 122 can be achieved. The hinged structure ensures that the end cover plate 122 maintains precise alignment when closed by gravity, avoiding sealing failure caused by misalignment, while limiting its opening and closing trajectory to prevent excessive overturning or jamming under water flow impact. The separable design at the bottom of the end cover plate 122 ensures that the water flow pressure is concentrated on the bottom contact surface, pushing the end cover plate 122 to open with less resistance, improving drainage response sensitivity, and quickly resetting to a fully closed state by gravity and hinge constraint when there is no water pressure, thus enhancing the dynamic drainage efficiency and static sealing performance of the end cover plate 122.
[0056] In one possible implementation, refer to Figure 1 , Figure 2 , Figure 3 A pivot shaft 123 may be provided on the end cover plate 122, and a pivot groove 124 may be provided on the end cover seat 121. The pivot shaft 123 is rotatably disposed within the pivot groove 124 to achieve a pivotal engagement between the end cover plate 122 and the end cover seat 121. Alternatively, the end cover plate 122 may be provided with a pivot groove 124, and the end cover seat 121 may be provided with a pivot shaft 123, which is rotatably disposed within the pivot groove 124 to achieve a pivotal engagement between the end cover plate 122 and the end cover seat 121. Optionally, a flexible scraper may also be integrated at the root of the pivot shaft 123. When the end cover plate 122 rotates, the flexible scraper can slide along the inner wall of the pivot groove 124 to automatically remove accumulated mud, sand, or ice crystals.
[0057] Understandably, the coordinated design of the pivot shaft 123 and the pivot groove 124 achieves stable guidance and low-friction movement of the end cover plate 122, ensuring that the end cover plate 122 always moves along a fixed trajectory during opening and closing. Furthermore, the separate design of the pivot shaft 123 and the pivot groove 124 simplifies the assembly process and facilitates the cleaning of accumulated impurities, improving the environmental adaptability and reliability of the water guiding device 1.
[0058] In one possible implementation, refer to Figure 1 , Figure 2 To enhance the self-closing capability of the end cover plate 122 under static conditions, the water guiding device 1 may also be provided with a counterweight 13. The counterweight 13 may be provided on the end cover plate 122 to increase the gravity on the end cover plate 122. Alternatively, to enhance the self-closing capability of the end cover plate 122 under static conditions, a torsion spring or tension spring may be provided between the end cover plate 122 and the end cover seat 121 to provide additional closing force through spring preload. Furthermore, to enhance the self-closing capability of the end cover plate 122 under static conditions, permanent magnets may be embedded in the contact surfaces between the bottom end of the end cover plate 122 and the end cover seat 121 to assist closing through magnetic attraction. The self-closing capability of the end cover plate 122 under static conditions can be enhanced by one or a combination of the above solutions; this application does not impose specific limitations.
[0059] Understandably, the counterweight 13 enhances the self-sealing capability of the end cover 122 under static conditions, ensuring a tight fit with the outlet 1211 to improve sealing. Simultaneously, the split counterweight design allows for flexible adjustment to accommodate the drainage pressure requirements of different vehicle models. Furthermore, the inertia of the counterweight 13 suppresses unexpected shaking of the end cover 122 caused by vehicle bumps or vibrations, further ensuring sealing stability under complex operating conditions.
[0060] In one possible implementation, the counterweight 13 can be a metal component. For example, the counterweight 13 can be made of lead alloy, tungsten alloy, stainless steel, galvanized steel, etc. Optionally, the counterweight 13 can also have multiple slots. A metal piece can be inserted into each slot to change the weight of the counterweight 13. Furthermore, a slide rail can be provided on the side of the end cover plate 122 near the outlet 1211. The counterweight 13 can be embedded in the slide rail. By changing the position of the counterweight 13 in the slide rail, the center of gravity of the end cover plate 122 can be changed, thereby adapting to different application scenarios.
[0061] Understandably, by using a metal counterweight 13, its high density can be fully utilized to increase the self-closing gravity of the end cover 122 within a limited volume, ensuring that the valve is tightly closed when there is no water flow, and effectively resisting unexpected opening caused by air pressure fluctuations or vibrations in the engine compartment.
[0062] In one possible implementation, refer to Figure 1 , Figure 2 The water guiding device 1 also includes a shock-absorbing pad 14. The shock-absorbing pad 14 can be disposed on the end cover plate 122. Alternatively, the shock-absorbing pad 14 can be disposed in the end face of the outlet 1211 of the end cover seat 121. Alternatively, the shock-absorbing pad 14 can be disposed on both the end face of the end cover plate 122 and the end face of the outlet 1211 of the end cover seat 121. The shock-absorbing pad 14 can be made of a soft-hard composite material. For example, the outer layer of the shock-absorbing pad 14 can be made of silicone to resist aging. The inner layer of the shock-absorbing pad 14 can be made of polyurethane to absorb vibration. The counterweight 13 can be pre-embedded inside the shock-absorbing pad 14. The shock-absorbing pad 14 can be injection molded to fix the counterweight 13, forming an integrated shock-absorbing-counterweight module, which simplifies the assembly process and prevents the counterweight 13 from falling off.
[0063] It is understandable that by setting the shock-absorbing pad 14, its elastic deformation characteristics can be used to compensate for the micro-unevenness between the sealing surfaces of the end cover plate 122 and the end cover seat 121, improve the contact fit of the end cover plate 122 when it is closed, effectively eliminate the sealing gap caused by vibration or processing tolerance, and enhance the ability to block odors and hot air.
[0064] In one possible implementation, the shock-absorbing pad 14 includes a plastic component. This plastic component can be made of silicone, fluororubber, EPDM rubber, etc.
[0065] Understandably, the elastic damping effect of plastic parts can absorb the vibration energy caused by vehicle bumps or water flow impact, reduce rigid collisions and noise between metal parts, avoid deformation or wear of end cover plate 122 due to long-term vibration, and extend the service life of water guiding device 1.
[0066] On the other hand, this application also provides a vehicle including the aforementioned water guiding device 1.
[0067] The vehicle provided in this application embodiment, by adopting the aforementioned water guiding device 1, can dynamically isolate odorous heat from the engine compartment using its self-sealing structure. When there is no drainage, the outlet 1211 remains closed, effectively preventing odors from seeping back into the air conditioning external circulation system through the water guiding pipe 11, significantly improving the cleanliness of the air inside the vehicle. When draining water, the water pressure automatically opens the valve to ensure that rainwater, car wash liquid, etc. are quickly discharged, avoiding water accumulation that could cause corrosion or electrical failures in the engine compartment. At the same time, the purely mechanical design does not rely on an electronic control unit, adapting to complex working conditions such as high temperature and vibration in the engine compartment, taking into account long-term sealing stability and low maintenance costs, and comprehensively improving the vehicle's environmental adaptability and driving health experience.
[0068] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
