Description

Technical Field

[0001] This application belongs to the field of automotive parts technology, and more specifically, relates to an automotive engine compartment drainage and air intake system and a vehicle. Background Technology

[0002] The engine compartment's drainage and air intake system is a crucial structural system for vehicle water management and air conditioning gas circulation, and it mainly consists of an air chamber and a drainage channel structure.

[0003] The air chamber is used to deliver the air drawn in through this gap into the passenger compartment to meet the air circulation needs of the passenger compartment. The air chamber can also prevent carbon monoxide in the cabin from being inhaled and causing poisoning when the air conditioning is on and the engine is idling.

[0004] The drainage channel structure is used to guide water flowing into the gap between the windshield and the hood to the outside of the vehicle for discharge; conventional drainage channel structures span the width of the vehicle body, making them bulky and affecting the layout and maintenance of the engine compartment. Utility Model Content

[0005] The purpose of this application is to provide an automotive engine compartment drainage and air intake system and vehicle, which aims to solve the problem that the drainage channel structure spans the width of the vehicle body, affecting the engine compartment layout and maintenance.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, embodiments of this application provide an automotive engine compartment drainage and air intake system, comprising: A ventilation cover, wherein the ventilation cover is provided with a left water inlet, a right air inlet and a right water inlet; An air chamber having an air inlet and an air outlet, the air inlet being connected to the right-side air inlet; the top plate of the air chamber is recessed downward in the middle, and a receiving space extending along the length of the air chamber is formed between the top plate and the ventilation cover, the receiving space being located below the right-side water inlet; A left-side drainage trough structure is located below the ventilation cover. The inlet of the left-side drainage trough structure is connected to the left-side water inlet, and the bottom of the left-side drainage trough structure is provided with a left-side drain outlet. The right-side drainage trough structure includes a drainage trough body, which is disposed within the accommodating space, and the opening of the drainage trough body is connected to the right-side water inlet; the first end of the drainage trough body extends along the length of the accommodating space to the outside of the air chamber, and has a right-side drainage outlet.

[0007] The solution shown in this application embodiment, compared with the prior art, includes a left water inlet and a right water inlet respectively opened at both ends of the ventilation cover; water on the ventilation cover flows from the middle to both sides until it flows into the water inlets on both sides, and then is discharged through the left drainage channel structure and the right drainage channel structure.

[0008] The water inlets are positioned on the left and right sides of the ventilation cover, respectively, and the drainage trough structures are correspondingly set as left and right drainage trough structures. By utilizing two separate drainage trough structures for drainage, the drainage trough structure is prevented from spanning the width of the vehicle body, thus reducing its footprint, decreasing the engine compartment size, increasing layout space, and optimizing the engine compartment layout. Furthermore, the left and right drainage trough structures are independently designed, do not interfere with each other, and are easy to install and remove, avoiding any restrictions on engine compartment maintenance. Reducing the volume of the drainage trough structure also reduces the volume of the air chamber it occupies, further increasing layout space and reducing the overall engine compartment size. The drainage trough body of the right-side drainage trough structure is located within the space formed by the top plate of the air chamber, making the engine compartment layout more compact and rational, facilitating engine compartment maintenance and repair work.

[0009] In conjunction with the first aspect, in one possible implementation, an installation gap is formed between the top plate of the air chamber and the body of the drainage trough.

[0010] In the above technical solution, the installation gap reduces the precision requirements of the drainage trough body and the top plate of the air chamber, while reducing the assembly difficulty and improving the assembly efficiency; at the same time, it improves the convenience of engine room maintenance, reduces the vibration transmission between the drainage trough body and the top plate of the air chamber, and reduces the noise generated by friction.

[0011] In some embodiments, the right-side drainage channel structure further includes: A drainage chamber is located on one side of the air chamber and is connected to the first end of the drainage trough body; the right-side drainage outlet is located at the bottom of the drainage chamber.

[0012] In the above technical solution, the drainage chamber can be installed in a position that can be adjusted according to the spatial layout of the engine room, so that the right drainage outlet avoids metal parts or electrical components in the engine room, thus avoiding the impact of drainage on electrical components and metal parts, while also improving the layout optimization of the engine room; the drainage chamber provides buffer and temporary storage space for water flow, improving the stability of drainage and reducing the risk of leakage.

[0013] In some embodiments, the right-side drainage channel structure further includes: The first mounting part is located on the outside of the drainage trough body, and the first mounting part is used to connect to the mounting frame inside the cabin; The second mounting part is located at the bottom of the drainage compartment and is used to connect the longitudinal beams of the engine room inside the engine room.

[0014] In the above technical solution, the first installation part and the second installation part simultaneously fix the water inlet end and the water outlet end of the right drainage trough structure to ensure its installation stability, ensure its working stability, and reduce its vibration and noise.

[0015] In some embodiments, the bottom of the drainage chamber is provided with a longitudinal drainage pipe, and the right-side drainage outlet is located at the lower end of the drainage pipe; The second mounting part includes: A snap-fit ​​plate is provided at the bottom of the drain pipe. The snap-fit ​​plate is circumferentially arranged around the right drain outlet. The snap-fit ​​plate is engaged with the opening on the longitudinal beam of the engine room. Multiple guide members are spaced apart at the lower end of the snap-fit ​​plate, and the guide members are inclined from top to bottom toward the center of the right drain outlet.

[0016] In the above technical solution, the snap-fit ​​connection enables a quick connection between the drainage compartment and the engine compartment longitudinal beam, and the connection strength is reliable, effectively resisting vibrations during vehicle operation and preventing the drainage compartment from loosening or shifting. Multiple guide components provide guidance during installation, allowing the snap-fit ​​plate to be inserted more smoothly into the openings in the engine compartment longitudinal beam, reducing the difficulty of alignment during installation and improving the ease of assembly.

[0017] In some embodiments, the right-side drainage channel structure further includes: The drainage pipe section is longitudinally connected to the first end of the drainage trough body and the drainage chamber.

[0018] In the above technical solution, the diversion pipe section can effectively reduce water splashing at the connection point, avoid vibration noise in the drainage chamber caused by water flow impact, reduce the risk of water sludge accumulation at the connection point, and improve the drainage efficiency and stability of the drainage system.

[0019] In conjunction with the first aspect, in one possible implementation, the air chamber includes: A water outlet pipe is located at the bottom of the inner cavity of the air chamber, and the water outlet pipe is used to discharge the liquid in the air chamber; A baffle plate is located at the bottom of the inner cavity of the air chamber, and the end of the baffle plate extends to the inlet of the water outlet pipe.

[0020] In the above technical solution, the baffle can block the dense airflow at the bottom, improve the condensation effect of water droplets in the air, and prevent a large amount of water vapor from being brought into the cab; it can also guide the liquid air passage in the air chamber, directing the dispersed liquid to the water outlet inlet, so that the water deposited in the inner cavity of the air chamber can be discharged in time.

[0021] In some embodiments, the air chamber includes: An air intake pipe section, wherein the air intake end of the air intake pipe section is fixed to the ventilation cover plate; An air outlet pipe section, wherein the air inlet end of the air outlet pipe section is connected to the air outlet end of the air inlet pipe section, and the air outlet end of the air outlet pipe section is fixedly connected to the air outlet side panel of the cabin.

[0022] In the above technical solution, the segmented structure is convenient to arrange according to the spatial layout of the cabin during installation, and the segmented structure is convenient to disassemble and assemble in parts, reducing installation difficulty and improving assembly efficiency.

[0023] In conjunction with the first aspect, one possible implementation also includes: A front bulkhead, which connects the ventilation cover and the shock absorber tower inside the cabin; the front bulkhead is located on one side of the air chamber and is used to shield the air chamber.

[0024] In the above technical solution, the front bulkhead is located on the front side of the air chamber, which can block the noise generated by the air chamber during operation from spreading to the front of the cabin and the outside. In conjunction with the noise reduction structure of the air chamber itself, it further reduces the overall noise of the drainage and air intake system.

[0025] Secondly, this application also provides a vehicle that uses the above-mentioned automobile engine compartment drainage and air intake system.

[0026] In the above technical solution, by adopting the aforementioned automotive engine compartment drainage and air intake system, two drainage channels are used to drain water separately, solving the problem of traditional drainage channel structures spanning the width of the vehicle body. This reduces the space occupied by the drainage channels, thereby reducing the size of the engine compartment, improving the layout within the engine compartment, and avoiding the restriction of the drainage channels on engine compartment maintenance. In addition, by adding a front bulkhead, the sound insulation effect of the engine compartment is improved, reducing the use of sound-absorbing materials such as sound-absorbing cotton and damping rubber sheets, improving the NVH performance of the entire vehicle, and reducing the overall vehicle cost and weight.

[0032] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "a few" means two or more, unless otherwise explicitly specified.

[0033] Please refer to the following: Figures 1 to 8 The present application will now describe the automotive engine compartment drainage and air intake system and the vehicle provided. The automotive engine compartment drainage and air intake system includes a ventilation cover 10, an air chamber 20, a left-side drainage trough structure, and a right-side drainage trough structure. The ventilation cover 10 has a left-side water inlet 14, a right-side air inlet 12, and a right-side water inlet 13. The air chamber 20 has an air inlet 23 and an air outlet 22, with the air inlet 23 connecting to the air inlet. The top plate of the air chamber 20 is recessed in the middle, forming a receiving space extending along the length of the air chamber 20 between the top plate and the ventilation cover 10. The receiving space is located below the water inlet. The left-side drainage trough structure is located below the ventilation cover 10, with its inlet connected to the left-side water inlet 14 and its bottom having a left-side drain outlet. The right-side drainage trough structure includes a drainage trough body 30, which is located within the receiving space, and its opening is connected to the right-side water inlet 13. The first end of the drainage trough body 30 extends along the length of the receiving space to the outside of the air chamber 20 and has a right-side drain outlet.

[0034] In this embodiment, the water inlet of the ventilation cover 10 includes a left water inlet 14 and a right water inlet 13 respectively opened at both ends of the ventilation cover 10; water on the ventilation cover 10 flows from the middle to both sides until it flows into the water inlets on both sides, and then is discharged through the left drainage channel structure and the right drainage channel structure. Since the air inlet of the ventilation cover 10 is opened in the right half of the ventilation cover 10, the installation space of the air chamber 20 and the right drainage channel structure is limited.

[0035] A water-blocking baffle 15 is provided between the right air inlet 12 and the right water inlet 13 on the ventilation cover 10. This water-blocking baffle 15 is used to block water flow and prevent external water from entering the air chamber 20 through the right air inlet 12. A mounting frame is provided in the cabin space to fix the ventilation cover 10. The mounting frame includes a front mounting frame, a left mounting frame, and a right mounting frame. The mounting frame only serves as a support structure to fix the ventilation cover 10 and the two drainage channel structures. The mounting frame is not shown in the figure.

[0036] The front mounting bracket is arranged along the length of the nacelle, and a first mounting hole is provided on the front mounting bracket. A first fixing part 11 is provided on the edge of the ventilation cover 10 away from the water inlet. The first fixing part 11 is arranged along the length direction and has multiple first fixing holes. The first fixing holes are fixedly connected to the first mounting holes one by one. The first fixing holes and the first mounting holes can be fixed by bolts, rivets, or clips.

[0037] Both the left and right mounting brackets are arranged along the width of the nacelle. The left mounting bracket connects to the left end of the ventilation cover 10, and the right mounting bracket connects to the right end of the ventilation cover 10. The left and right mounting brackets are symmetrically arranged. Taking the right mounting bracket as an example, it has several second mounting holes, and several second fixing holes are provided at the right end of the ventilation cover 10. During installation, the second mounting holes and second fixing holes are fixed one-to-one, and can be fixed by bolts, rivets, or clips.

[0038] Regarding the left-side drainage trough structure, it includes a water inlet pipe 50 located within the engine compartment. A left-side water inlet 14 connects to the water inlet pipe 50 and discharges water through it. The upper end of the water inlet pipe 50 has an outwardly extending connecting structure with a through hole. During installation, the connecting structure extends outward to the upper or lower end of the left-side mounting bracket of the ventilation cover 10 and is fixed to the left-side mounting bracket using clips or screws. Since the left half lacks an air inlet and does not involve the air chamber 20, there are no space constraints for drainage in the left half. Therefore, the auxiliary drainage structure of the left half is not described in detail in this embodiment. Optionally, a snap-fit ​​buckle 51 is provided at the bottom of the water inlet pipe 50, which snaps into and fixes to the left-side mounting bracket. The left-side drain outlet at the bottom of the water inlet pipe 50 communicates with the outside. The left-side mounting bracket is a sheet metal structure.

[0039] For the air chamber 20, the inlet end of the air chamber 20 is connected to the air inlet of the ventilation cover 10, and the outlet end of the air chamber 20 is fixedly connected to the air outlet side panel 41. A V-shaped airflow channel is formed in the inner cavity of the air chamber 20. Since the outlet end of the air chamber 20 is located on the side of the water inlet away from the air inlet, the water inlet on the ventilation cover 10 is located above the air chamber 20.

[0040] Regarding the right-side drainage trough structure, the right-side drainage trough structure needs to be connected to the right-side water inlet 13. Therefore, the drainage trough structure is located above the middle of the air chamber 20, so that the water entering from the right-side water inlet 13 can be discharged from the cabin through the right-side drainage trough body 30.

[0041] The right-side drainage trough structure is a U-shaped trough structure with an open top. Its length follows the arrangement direction of the right-side water inlet 13, and both ends are closed along its length. A right-side drainage outlet is provided on the side closest to the right edge of the engine compartment. The right-side drainage trough structure includes a first side plate and a second side plate arranged along its length. The height of both the first and second side plates is determined by their distance from the ventilation cover 10, ensuring that the upper ends of the first and second side plates are in contact with the ventilation cover 10, preventing water entering from the water inlet from flowing out along the lower surface of the ventilation cover 10. The upper ends of the end plates at both ends of the right-side drainage trough structure are also in contact with the lower surface of the ventilation cover 10.

[0042] The automotive engine compartment drainage and air intake system provided in this application has the following advantages compared with the prior art: (1) Traditional drainage channel structures span the width of the vehicle body, resulting in a bulky and cumbersome structure that affects the layout and maintenance of the engine compartment. In this embodiment, the water inlets are set as the left water inlet 14 and the right water inlet 13 at both ends of the ventilation cover 10, and the drainage channel structures are correspondingly set as the left drainage channel structure and the right drainage channel structure. By using two drainage channel structures to drain water separately, the drainage channel structure is avoided from spanning the width of the vehicle body, thus reducing the space occupied by the drainage channel, reducing the size of the engine compartment, increasing the layout space, and improving the layout inside the engine compartment. At the same time, the left drainage channel structure and the right drainage channel structure are set separately, do not affect each other, are easy to disassemble and assemble, and avoid the limitation of the drainage channel on engine compartment maintenance.

[0043] (2) Traditional drainage trough structures are relatively large, requiring the air chamber 20 to expand its own volume to meet the internal volume requirements of the air chamber 20, which in turn increases the volume of the air chamber 20 and affects the cabin layout. In this embodiment, a left-side drainage trough structure and a right-side drainage trough structure are provided. By improving the volume of the drainage trough structure, the volume of the air chamber 20 that it cooperates with is also reduced, thereby reducing the area occupied by the air chamber 20, increasing the layout space, and reducing the cabin size.

[0044] (3) The drainage trough body 30 of the right drainage trough structure is located in the accommodating space formed by the top plate of the air chamber 20, which further saves the cabin space, makes the cabin layout more compact and reasonable, and facilitates the maintenance and repair work of the cabin.

[0045] In some embodiments, the housings of both the air chamber 20 and the drainage channel structure can be made of plastic.

[0046] The air chamber 20 can be injection molded as a single piece or injection molded in multiple segments sequentially. When the air chamber 20 is injection molded in segments, each segment of the air chamber 20 is injection molded separately, and the molded segments are then sequentially sealed and connected by means of clamping or bolts.

[0047] Traditional air chambers 20 are formed by sheet metal processing, which often results in poor sealing reliability due to limitations in processing precision and forming technology. In this embodiment, the air chamber 20 is made of plastic to ensure its airtightness and prevent carbon monoxide leakage from the cabin due to seal failure.

[0048] Traditional drainage channel structures are formed by sheet metal processing, which often results in poor sealing reliability due to limitations in processing precision. In this embodiment, the drainage channel structure is also made of plastic to ensure its sealing performance, prevent leakage failure, and eliminate the risks of leakage corrosion and electrical component failure.

[0049] In this embodiment, the automotive engine compartment drainage and air intake system has an independent plastic air chamber 20 and an independent plastic drainage channel structure, which enhances sealing reliability. The plastic shell is lightweight, which helps to reduce the overall vehicle weight and improve vehicle economy; in addition, the processing cost of the plastic shell is relatively low and the production efficiency is high, which can reduce the manufacturing cost of the drainage and air intake system.

[0050] In some embodiments, see Figure 2 An installation gap is formed between the top plate of the air chamber 20 and the drainage trough body 30.

[0051] The top plate of the air chamber 20 is recessed below the right-side water inlet 13, forming a receiving space. This receiving space is an upward-opening elongated groove structure, with both ends extending to the ends of the air chamber 20. The drainage trough body 30 is installed within the receiving space, and there are installation gaps between the bottom and both side walls of the drainage trough body 30 and the top plate of the air chamber 20. These installation gaps provide convenient space for the installation and disassembly of the drainage trough body 30.

[0052] During installation and disassembly, due to the installation gap, workers can smoothly install the drainage trough body 30 within the accommodating space without needing to fit the top plate of the drainage trough body 30 and the air chamber 20 together. This reduces the precision requirements for the drainage trough body 30 and the top plate of the air chamber 20, while also reducing assembly difficulty and improving assembly efficiency. At the same time, it enhances the convenience of engine room maintenance and improves the problem of traditional drainage trough structures being too large and bulky, thus hindering maintenance.

[0053] In addition, the air chamber 20 and the drainage trough body 30 operate independently, and the installation gap between them provides a certain vibration space for the drainage trough body 30 and the air chamber 20. This reduces vibration transmission between the top plates of the drainage trough body 30 and the air chamber 20 to a certain extent, and reduces noise caused by friction.

[0054] In some embodiments, the aforementioned right-side drainage channel can be adopted as follows: Figure 4 , Figure 5 , Figure 6 The structure shown is as follows. The right-side drainage trough structure also includes a drainage chamber 33, which is located on one side of the air chamber 20 and is connected to the first end of the drainage trough body 30; the right-side drainage outlet is located at the bottom of the drainage chamber 33.

[0055] The drainage chamber 33 is located on the side of the air chamber 20 away from the left drainage channel, allowing water from the right drainage channel to flow towards the right edge of the nacelle until it is discharged from the right edge of the nacelle. The drainage chamber 33 is located on the right side of the air chamber 20 and is lower than the top plate of the air chamber 20. The drainage chamber 33 has an inclined tubular structure, with its upper end connected to the outlet end of the drainage channel body 30 and its lower end extending to the lower part of the nacelle.

[0056] The drainage chamber 33 is used to connect to the drainage trough and guide the water in the drainage trough out of the trough, thus achieving a drainage function. In this embodiment, the drainage chamber 33 can be replaced by a drainage plastic pipe fixedly installed at the outlet end of the drainage trough body 30. Compared to direct drainage from the outlet end of the drainage trough body 30, the drainage chamber 33 can be installed in a position that can be adjusted according to the spatial layout of the engine compartment, so that the right-side drainage outlet avoids metal parts or electrical components in the engine compartment, avoiding the impact of drainage on electrical components and metal parts, and also optimizing the layout of the engine compartment.

[0057] Furthermore, the flow cross-section of the drainage chamber 33 is larger than that of the drainage trough body 30, providing a buffer and temporary storage space for the water flow. When the water flow into the drainage chamber 33 from the right inlet 13 is large, the drainage trough body 30 first transports the water to the drainage chamber 33, and then discharges it from the right drain outlet at the bottom of the drainage chamber 33. The drainage chamber 33 prevents water from accumulating in the drainage trough body 30 due to excessive instantaneous flow, improving drainage stability and reducing the risk of leakage. In addition, the drainage chamber 33 drains the accumulated water in the drainage trough body 30, and the water flow is buffered in the drainage chamber 33 before being discharged smoothly, reducing the noise caused by water flow impact.

[0058] Optionally, the drainage chamber 33 and the drainage trough body 30 are fixed with bolts or snap-fit, and the connection is sealed. The drainage chamber 33 and the drainage trough body 30 are detachably connected in the above manner, so that the drainage chamber 33 can be easily disassembled and repaired separately when replacement or maintenance is required, thus improving the convenience of maintenance.

[0059] In some embodiments, the aforementioned right-side drainage channel can be adopted as follows: Figure 5 , Figure 6 The structure shown is as follows. The right-side drainage trough structure also includes a first mounting part 31 and a second mounting part. The first mounting part 31 is located on the outside of the drainage trough body 30 and is used to connect to the mounting frame inside the engine room; the second mounting part is located at the bottom of the drainage compartment 33 and is used to connect to the engine room longitudinal beam inside the engine room.

[0060] The first mounting part 31 is located on the outside of the drainage trough body 30 and is used to fix the water inlet end of the right drainage trough structure; while the second mounting part is located at the bottom of the drainage chamber 33 and is used to fix the water outlet end of the right drainage trough structure. The first mounting part 31 and the second mounting part simultaneously fix the water inlet end and the water outlet end of the right drainage trough structure to ensure its installation stability, its operational stability, and reduce its vibration and noise.

[0061] The weight of the right-side drainage trough structure itself and the weight of the water flow are transferred to the mounting frame and the nacelle longitudinal beams through the first mounting part 31 and the second mounting part, respectively. This avoids the problem of structural deformation caused by excessive stress at a single mounting point, extends the service life of the right-side drainage trough structure, and also reduces the strength requirements of connecting components, indirectly saving material costs. In addition, the multi-point installation method is more conducive to the spatial arrangement within the nacelle, improving the compactness of the nacelle layout.

[0062] The mounting brackets within the cabin include the aforementioned front mounting bracket, left mounting bracket, and right mounting bracket. The left drainage trough structure is fixed to the left mounting bracket. The right water inlet 13 is longer than the left water inlet 14, therefore the right drainage trough structure is longer and can be fixed to the right mounting bracket and / or the front mounting bracket.

[0063] The first mounting section 31 has at least one.

[0064] When there is only one first mounting part 31, the first mounting part 31 can be set with reference to the mounting structure of the left drainage channel structure. The first mounting part 31 is located at the right end of the right mounting part, extends outward, and has a mounting hole; the first mounting part 31 extends to the upper end of the right mounting bracket and is fixed to the right mounting bracket by a snap fastener.

[0065] When there are two first mounting parts 31, to ensure the stability of the right-side drainage channel structure, the two first mounting parts 31 can be located at opposite ends of the length of the right-side drainage channel structure, namely the left mounting part and the right mounting part. The left mounting part is fixed to the front mounting bracket by a snap fastener, and the right mounting part is fixed to the right mounting bracket by a snap fastener. The two first mounting parts 31 are respectively mounted on the right mounting bracket and the front mounting bracket, which can further improve its stability and reduce the noise generated by resonance with the mounting bracket.

[0066] A through hole is provided on the longitudinal beam of the engine room, and a second mounting part is provided at the bottom of the drainage compartment 33. During installation, the second mounting part is engaged and fixed with the opening of the longitudinal beam of the engine room, so that the right-side drainage outlet at the bottom of the drainage compartment 33 is located in the opening of the longitudinal beam of the engine room.

[0067] Specifically, such as Figure 6As shown, the bottom of the drainage compartment 33 is provided with a longitudinal drainage pipe 34, and the right-side drainage outlet is opened at the lower end of the drainage pipe 34; the second mounting part includes a snap-fit ​​plate 35 and multiple guide members 36. The snap-fit ​​plate 35 is located at the bottom of the drainage pipe 34, and the snap-fit ​​plate 35 is circumferentially arranged around the right-side drainage outlet. The snap-fit ​​plate 35 is engaged with the opening on the longitudinal beam of the engine room; multiple guide members 36 are spaced apart at the lower end of the snap-fit ​​plate 35, and the guide members 36 are inclined from top to bottom toward the center of the right-side drainage outlet.

[0068] The longitudinal drain pipe 34 provides guidance for drainage, reduces water residue at the bottom of the drain chamber 33, and prevents water splashing; it also provides a carrier for the second installation part, confining the second installation part to the outer periphery of the drain pipe 34, and limiting its connection with the engine room longitudinal beam to improve the stability of the drain chamber 33.

[0069] The snap-fit ​​plate 35 is circumferentially positioned around the right-side drain outlet and engages with the opening on the engine compartment longitudinal beam. This snap-fit ​​structure eliminates the need for additional fasteners, additional holes, and other structures, simplifying the installation process and improving assembly efficiency. The snap-fit ​​connection enables a quick connection between the drain compartment 33 and the engine compartment longitudinal beam, and the connection strength is reliable, effectively resisting vibrations during vehicle operation and preventing the drain compartment 33 from loosening or shifting.

[0070] Multiple guide members 36 are spaced apart at the lower end of the snap-fit ​​plate 35 and are inclined. They serve as guides during installation, allowing the snap-fit ​​plate 35 to be inserted more smoothly into the openings in the naval longitudinal beams, reducing the difficulty of alignment during installation and improving the ease of assembly. In situations where naval space is limited, the above installation structure can reduce installation time and operational difficulty.

[0071] Optionally, the snap-fit ​​plate 35 has a rectangular cross-section, and there are four guide members 36. The four guide members 36 are respectively disposed on the four sides of the snap-fit ​​plate 35.

[0072] In some embodiments, the aforementioned right-side drainage channel can be adopted as follows: Figure 5 , Figure 6 The structure shown is as follows. The drainage trough structure on the right side also includes a drainage pipe section 32, which is longitudinally connected to the first end of the drainage trough body 30 and the drainage chamber 33.

[0073] To accommodate the compact interior space of the cabin, there may be a height difference or positional deviation between the drainage trough body 30 and the drainage chamber 33. The diversion pipe section 32 is used to longitudinally guide the water flow within the drainage trough body 30, ensuring a smooth flow into the drainage chamber 33. The diversion pipe section 32 effectively reduces water splashing at the connection point, prevents noise caused by vibration of the drainage chamber 33 due to water flow impact, and reduces the risk of water accumulation at the connection point, thus improving the drainage efficiency and stability of the drainage system. The diversion pipe section 32 and the drainage trough body 30, as well as the diversion pipe section 32 and the drainage chamber 33, are all smoothly connected.

[0074] The drainage tube section 32 can be a vertical tube or an inclined tube.

[0075] In some embodiments, the air chamber 20 described above employs, for example... Figure 2 , Figure 4 , Figure 7 The structure shown. See also Figure 2 and Figure 7 The air chamber 20 includes a water outlet pipe and a baffle plate 21. The water outlet pipe is located at the bottom of the inner cavity of the air chamber 20 and is used to discharge the liquid inside the air chamber 20. The baffle plate 21 is located at the bottom of the inner cavity of the air chamber 20 and its end extends to the inlet of the water outlet pipe.

[0076] Some water will enter the right-side air inlet 12 as tiny droplets and then into the inner cavity of the air chamber 20. After entering the air chamber 20, the water in the air will condense on the inner wall of the air chamber 20 or deposit inside the air chamber 20 due to changes in airflow direction and speed. The water deposited in the inner cavity of the air chamber 20 needs to be drained promptly; therefore, a water outlet pipe needs to be installed at the bottom of the inner cavity of the air chamber 20.

[0077] To improve drainage, a baffle plate 21 is installed at the bottom of the inner cavity of the air chamber 20. When water droplets deposited on the inner wall flow to the bottom of the inner cavity of the air chamber 20, they are blocked by the baffle plate 21, so that the water droplets can only flow along the baffle plate 21 toward the outlet pipe.

[0078] The baffle 21 can block the dense airflow at the bottom, improve the condensation effect of water droplets in the air, and prevent a large amount of water vapor from being brought into the cab; it can also guide the liquid air passage in the air chamber 20, directing the dispersed liquid to the water outlet inlet.

[0079] In some embodiments, such as Figure 2 As shown, the air chamber 20 includes an air inlet pipe section and an air outlet pipe section; the air inlet end of the air inlet pipe section is fixed to the ventilation cover plate 10; the air inlet end of the air outlet pipe section is connected to the air outlet end of the air inlet pipe section, and the air outlet end of the air outlet pipe section is fixedly connected to the air outlet side panel 41 of the cabin.

[0080] The air chamber 20 is configured as an intake pipe section and an exhaust pipe section. The segmented structure makes it easy to arrange according to the spatial layout of the cabin during installation, and the segmented structure also facilitates partial disassembly and assembly, reducing installation difficulty and improving assembly efficiency.

[0081] Furthermore, the length of the air inlet duct section needs to match the size of the right-side air inlet 12, and the air outlet end of the air outlet duct section needs to match the size of the air conditioning vent. A single integrated design would increase the manufacturing difficulty and cost of the air chamber 20. Therefore, a segmented structure can reduce the manufacturing difficulty and cost of the air chamber 20.

[0082] Optionally, the connection between the air inlet duct section and the air outlet duct section is located within the containment space.

[0083] Multiple first connecting parts 24 are provided at the air intake end of the air intake pipe section. The first connecting parts 24 extend outward and are fixed to the front fixing bracket or the ventilation cover 10 by snap fasteners. For example, a snap fastener structure is integrally injection molded at the bottom of the ventilation cover 10, and the ventilation cover 10 is fixed to the first connecting part 24 by the snap fasteners passing through the connecting holes on the first connecting parts 24.

[0084] Similarly, a second connecting part 25 is provided at the air outlet end of the air outlet duct section. The second connecting part 25 is attached to the side wall of the air outlet side panel 41 and is fixed to the air outlet side panel 41 by bolts.

[0085] In some embodiments, such as Figure 2 As shown, the automotive engine compartment drainage and air intake system also includes a front bulkhead 40, which connects the ventilation cover 10 and the shock absorber tower 60 inside the engine compartment; the front bulkhead 40 is located on the front side of the air chamber 20 and is used to shield the air chamber 20.

[0086] The front bulkhead 40 is located in front of the air chamber 20 and can block the noise generated by the air chamber 20 during operation from propagating to the front of the engine compartment and the outside. In conjunction with the noise reduction structure of the air chamber 20 itself, it further reduces the overall noise of the drainage and air intake system. This reduces the reliance on a large amount of sound-absorbing materials such as sponge and damping adhesive on the outer bulkhead of the air chamber 20, which helps to reduce costs and improves the overall performance of the vehicle.

[0087] The front panel 40 and the outlet side panel are located on both sides of the air chamber 20, which isolates the air chamber 20 from the outside and can significantly reduce the noise generated by the air chamber 20, thereby reducing the use of sound-absorbing materials such as sound-absorbing cotton and damping rubber sheets.

[0088] Optionally, there can be multiple front bulkheads 40, which are distributed at intervals along the length of the vehicle body to form a multi-layer noise reduction structure, thereby improving the NVH performance of the whole vehicle and reducing the cost and weight of the whole vehicle.

[0089] Based on the same inventive concept, this application also provides a vehicle that uses the above-mentioned automobile engine compartment drainage and air intake system.

[0090] Compared with the prior art, the vehicle provided in this application has the following advantages: By adopting the above-mentioned automotive engine compartment drainage and air intake system, and using two drainage channel structures to drain water separately, the problem of the traditional drainage channel structure spanning the width of the vehicle body is solved, the space occupied by the drainage channel is reduced, the engine compartment size is reduced, the layout space is increased, the layout inside the engine compartment is improved, and the limitation of the drainage channel on engine compartment maintenance is avoided; in addition, by adding the front bulkhead 40, the sound insulation effect of the engine compartment is improved, the use of sound-absorbing cotton and damping rubber sheets and other sound insulation and absorption materials is reduced, the NVH performance of the whole vehicle is improved, and the cost and weight of the whole vehicle are reduced.

[0091] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
