Description

Technical Field

[0001] This application relates to the field of vehicles, and more particularly to a vehicle hood assembly and a vehicle. Background Technology

[0002] With the rapid development of the automotive industry, vehicle design is gradually evolving towards streamlined, low-drag, and aesthetically pleasing designs. Currently, the front-end designs of both gasoline and hybrid vehicles generally adopt a closed design (such as no grille) to reduce the drag coefficient and improve overall aerodynamic performance. However, while optimizing the appearance, this design also brings significant thermal management challenges.

[0003] In conceiving and implementing this application, the applicant discovered at least the following problems: Currently, the closed front grille limits the air intake capacity of traditional radiator grilles, resulting in restricted airflow inside the engine compartment and difficulty in effectively dissipating heat. Especially in high-temperature environments or under high-load conditions, the temperature inside the engine compartment may rise rapidly, leading to thermal damage or performance degradation of critical components such as the engine cylinder head cover, cooling pipes, and high-voltage wiring harnesses.

[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Summary of the Invention

[0005] The main objective of this application is to provide a vehicle hood assembly and vehicle that improves thermal management efficiency.

[0006] To achieve the above objectives, this application provides a vehicle hood assembly disposed in a vehicle, the vehicle hood assembly comprising:

[0007] The nacelle canopy body has a first air intake, and the nacelle canopy body surrounds the nacelle.

[0008] An air guide assembly is located on the nacelle canopy body. The air guide assembly includes an air guide component, which has an air guide channel. The air guide channel has a connected air inlet and an air outlet.

[0009] The air inlet is connected to the first air intake, and the air outlet is connected to the engine compartment to allow air from outside the vehicle to enter the engine compartment.

[0010] The beneficial effects of this application are: by combining an independent air guide with the first air inlet, external cold air is directly introduced into the cabin, avoiding interference from high-temperature air, significantly reducing the temperature of key components in the cabin, and improving thermal management efficiency.

[0011] Based on the above technical solution, the following improvements can be made to this application.

[0012] In some alternative implementations, the air guide is located at the top of the nacelle.

[0013] The above-mentioned technical solution has the following advantages or beneficial effects: it utilizes the principle of hot air rising naturally and cold air flowing from top to bottom, which helps to form more effective temperature stratification and air convection. It can more effectively cool the hot air accumulated in the upper part of the cabin, prevent heat from accumulating at the top, thereby optimizing the overall temperature field distribution in the cabin and improving heat dissipation efficiency.

[0014] In some alternative embodiments, the canopy body is also provided with a grille, the grille having a second air intake that is connected to the cabin.

[0015] Along the height of the vehicle, the first air intake and the second air intake are spaced apart, with the first air intake located above the second air intake.

[0016] The above technical solution has the following advantages or beneficial effects: it provides a traditional heat dissipation path through the second air intake of the grille, ensuring the heat dissipation compatibility of the closed front face vehicle, while improving the overall thermal management efficiency.

[0017] In some alternative implementations, the air guide assembly further includes a rain shield disposed on the air guide and located within the air guide channel.

[0018] The above technical solution has the following advantages or beneficial effects: the setting of the rain shield avoids rainwater from directly contacting the high-voltage wiring harness, electrical components and metal parts in the engine compartment, effectively preventing short circuits, corrosion and rust caused by rainwater intrusion, and significantly improving the vehicle's operational safety and the long-term reliability of various components in severe weather.

[0019] In some alternative embodiments, there are at least two rain shields, including a first rain shield and a second rain shield, which are spaced apart along the extension direction of the air guide.

[0020] The above technical solution has the following advantages or beneficial effects: setting at least two first rain-blocking components and second rain-blocking components arranged at intervals along the airflow direction constitutes a multi-level, tiered rainproof barrier, which enhances the reliability of rain protection.

[0021] In some alternative implementations, the air guide includes a first air guide section, a second air guide section, a third air guide section, and a fourth air guide section;

[0022] The first air guide section is equipped with an air inlet, the fourth air guide section is equipped with an air outlet, the second air guide section is connected to the end of the first air guide section away from the air inlet, and the third air guide section is connected between the second air guide section and the fourth air guide section.

[0023] The second air guide section is an arc-shaped section. The extension direction of the first air guide section matches the extension direction of the second air guide section. The extension direction of the fourth air guide section has an angle with the extension direction of the first air guide section.

[0024] The above-mentioned technical solution has the following advantages or beneficial effects: the segmented air guide structure enables the phased guidance of cold air, reducing turbulence and energy loss in airflow. The arc design of the second air guide section optimizes the airflow direction, and the transition connection of the third air guide section avoids abrupt changes in airflow, thereby improving the flow efficiency of cold air entering the cabin.

[0025] In some alternative embodiments, the first rain shield is disposed on the bottom wall of the second air guide section and has a first gap between it and the top wall of the second air guide section;

[0026] The second rain shield is located on the top wall of the fourth air guide section and has a second gap between it and the bottom wall of the fourth air guide section. The second rain shield is located at the air outlet.

[0027] The above technical solution has the following advantages or beneficial effects: it achieves layered rainwater blocking through multi-level rainproof components, while preserving the flow path of cold air, thus balancing waterproof performance and heat dissipation efficiency.

[0028] In some alternative implementations, the air guide assembly further includes a water guide box disposed in the fourth air guide section, and a second rain shield is configured to be located on the water guide box to guide liquid in the air guide channel into the water guide box.

[0029] The above technical solution has the following advantages or beneficial effects: the connection design between the second rain shield and the water guide box prevents rainwater from splashing onto electronic components and causing short circuits.

[0030] In some alternative implementations, at least one of the first rain shield and the second rain shield is a baffle.

[0031] The above technical solution has the following advantages or beneficial effects: limiting the rain shield to a baffle form emphasizes the simplicity, reliability, and economy of the structure. The baffle structure is simple, easy to manufacture and process, and inexpensive; it is convenient to install and easy to fix to the inner wall of the air guide; its flat or specially shaped surface can effectively block and guide liquid, and its performance is reliable.

[0032] In addition, this application also provides a vehicle including the aforementioned vehicle hood assembly.

[0034] By combining an independent air guide with the first air intake, external cold air is directly introduced into the cabin, avoiding interference from high-temperature air, significantly reducing the temperature of key components in the cabin, and improving thermal management efficiency.

[0065] With the rapid development of the automotive industry, vehicle design is gradually evolving towards streamlined, low-drag, and aesthetically pleasing designs. Currently, the front-end designs of both gasoline and hybrid vehicles generally adopt a closed design (such as no grille) to reduce the drag coefficient and improve overall aerodynamic performance. However, while optimizing the appearance, this design also brings significant thermal management challenges.

[0066] Currently, closed-off front grilles limit the air intake capacity of traditional radiator grilles, resulting in restricted airflow within the engine compartment and difficulty in effectively dissipating heat. Especially in high-temperature environments or under high-load conditions, the temperature inside the engine compartment may rise rapidly, leading to thermal damage or performance degradation of critical components such as the engine cylinder head cover, cooling pipes, and high-voltage wiring harnesses.

[0070] like Figures 1 to 6 As shown, this application provides a vehicle hood assembly 100, disposed in a vehicle, the vehicle hood assembly 100 including:

[0071] The nacelle canopy body 110 has a first air inlet 111, and the nacelle canopy body 110 forms a nacelle 112.

[0072] An air guide assembly 120 is provided on the nacelle canopy body 110. The air guide assembly 120 includes an air guide component 123. The air guide component 123 has an air guide channel 124. The air guide channel 124 has a connected air inlet 1241 and an air outlet 1242.

[0073] The air inlet 1241 is connected to the first air inlet 111, and the air outlet 1242 is connected to the engine compartment 112 so that air from outside the vehicle can enter the engine compartment 112.

[0074] It should be noted that the engine compartment cover body 110 refers to the structural component that covers the front of the vehicle's engine compartment, used to form the engine compartment 112 and support other components.

[0075] For example, a front hull cover made of metal or plastic.

[0076] In some embodiments, the hood body 110 constitutes a cover for the front engine compartment or front cargo compartment of a vehicle, and its interior encloses a cabin 112 for accommodating various vehicle components (such as drive units, controllers, wiring harnesses, etc.).

[0077] The hood body 110 has one or more first air intakes 111 on its forward-facing side (in the normal driving posture of the vehicle). The first air intake 111 can be a grille, a louver, or other structure that allows air to pass through.

[0078] It should be noted that the first air inlet 111 refers to the opening structure used to introduce external cold air.

[0079] For example, a rectangular or trapezoidal opening is provided on the top of the canopy body 110.

[0080] It should be noted that the air guide assembly 120 refers to a structural assembly used to guide airflow, including the air guide element 123.

[0081] It should be noted that air guide component 123 refers to a structural component with internal channels used to achieve directional airflow.

[0082] For example, a hollow structure composed of multiple air-guiding sections (such as arc-shaped sections and straight sections).

[0083] It should be noted that the air guide channel 124 refers to the air flow path inside the air guide component 123, which connects the air inlet 1241 to the air outlet 1242.

[0084] For example, a hollow channel with a rectangular, trapezoidal, or polygonal cross-section.

[0085] In some embodiments, the air guide assembly 120 is fixedly mounted on the hood body 110. The air guide 123 defines a continuous air guide channel 124. The air guide channel 124 has an air inlet 1241 and an air outlet 1242. The air inlet 1241 corresponds to and is sealed to a first air inlet 111 on the hood body 110, ensuring that outside air can only enter the air guide channel 124 through the first air inlet 111. The air outlet 1242 faces inwards towards the interior of the hood 112, allowing air flowing from the air guide channel 124 to directly enter the hood 112.

[0086] With the above configuration, namely, by combining the independent air guide 123 with the first air inlet 111, external cold air is directly introduced into the cabin 112, avoiding interference from high-temperature air, significantly reducing the temperature of key components in the cabin, and improving thermal management efficiency.

[0087] Specifically, a first air intake 111 and a connected air guide 123 are provided on the upper part of the hood body 110, forming an independent upper cooling airflow channel. This design can utilize the air pressure difference above the hood to force cold air from outside the vehicle into the top of the engine compartment 112 when the vehicle is in motion, which is particularly effective in supplementing the insufficient air intake of the grille 113 when the vehicle is at low speed or idling, improving the problem of heat accumulation in the engine compartment, especially in the upper space, and improving the overall heat dissipation efficiency.

[0088] In some embodiments, a sealing structure is provided between the hood body 110 and the air guide assembly 120, and the sealing structure is a rubber strip.

[0089] In some embodiments, a rubber strip refers to a seal made of an elastic material.

[0090] For example, the rubber strip can be a strip-shaped seal made of silicone rubber or nitrile rubber.

[0091] It should be noted that the rubber strip fits the connection surface between the hood body 110 and the air guide assembly 120 through elastic deformation, preventing rainwater from seeping in from the connection point.

[0092] The sealing performance between the hood body 110 and the air guide assembly 120 is enhanced by a rubber strip sealing structure to prevent rainwater from seeping in from the connection.

[0093] In some alternative implementations, the air guide 123 is located on top of the nacelle 112.

[0094] The above-mentioned technical solution has the following advantages or beneficial effects: it utilizes the principle of hot air rising naturally and cold air flowing from top to bottom, which helps to form more effective temperature stratification and air convection. It can more effectively cool the hot air accumulated in the upper part of the cabin, prevent heat from accumulating at the top, thereby optimizing the overall temperature field distribution in the cabin and improving heat dissipation efficiency.

[0095] In turn, the cooling air flowing out of the air outlet 1242 can be replenished from the upper part of the cabin, which helps to eliminate the accumulation of hot air at the top and form more effective temperature stratification and convection.

[0096] In some alternative embodiments, the canopy body 110 is also provided with a grille 113, the grille 113 having a second air inlet 1131, the second air inlet 1131 being connected to the cabin 112.

[0097] Along the height direction of the vehicle, the first air intake 111 and the second air intake 1131 are spaced apart, and the first air intake 111 is located above the second air intake 1131.

[0098] The above technical solution has the following advantages or beneficial effects: the second air intake 1131 of the grille 113 provides a traditional heat dissipation path, ensuring the heat dissipation compatibility of the closed front face vehicle, while improving the overall thermal management efficiency.

[0099] The second air intake 1131 of the grille 113 serves as an auxiliary air intake path to ensure the normal operation of the traditional heat dissipation function, while complementing the first air intake 111 to improve the overall heat dissipation efficiency.

[0100] The air guide assembly 120 can be integrated above the hood body 110 without compromising the overall appearance of the vehicle. The upper air guide duct 124 and the lower air intake grille (second air intake 1131) coexist to form a high-low complementary three-dimensional air intake system, which enhances the redundancy and adaptability of the heat dissipation effect, while ensuring the normal function of the traditional heat dissipation system.

[0101] In some embodiments, a grille 113 with a second air intake 1131 is provided below the front of the hood body 110, which also communicates with the engine compartment 112. Along the height direction of the vehicle, the first air intake 111 and the second air intake 1131 are spaced vertically apart, with the first air intake 111 located above the second air intake 1131. This constitutes a high-low dual-intake system.

[0102] In some embodiments, the size of the first air inlet 111 is larger than the size of the second air inlet 1131.

[0103] In some alternative embodiments, the air guide assembly 120 further includes a rain shield disposed on the air guide 123 and located within the air guide channel 124.

[0104] The above technical solution has the following advantages or beneficial effects: the setting of the rain shield avoids rainwater from directly contacting the high-voltage wiring harness, electrical components and metal parts in the engine compartment, effectively preventing short circuits, corrosion and rust caused by rainwater intrusion, and significantly improving the vehicle's operational safety and the long-term reliability of various components in severe weather.

[0105] It should be noted that the rain shield is mounted on the air guide 123 and extends into the internal space of the air guide channel 124. Its function is to physically block and change the path of raindrops that may enter with the air intake.

[0106] It should be noted that the rainproof component refers to the physical structure used to prevent rainwater from entering the air duct 124 or the cabin 112.

[0107] For example, the rain shield can be a metal plate, a plastic plate, or a corrugated structural member.

[0108] In some alternative embodiments, there are at least two rain shields, including a first rain shield 121 and a second rain shield 122, which are spaced apart along the extension direction of the air guide 123.

[0109] The above technical solution has the following advantages or beneficial effects: setting at least two first rain-blocking components 121 and second rain-blocking components 122 arranged at intervals along the airflow direction constitutes a multi-level, tiered rainproof barrier, which enhances the reliability of rain protection.

[0110] Specifically, the first rain-blocking element 121 can serve as the first line of defense, intercepting most raindrops. Even if a small number of raindrops or water mist bypass the first line of defense, the subsequent second rain-blocking element 122 can serve as a second line of defense and provide effective supplementary protection. The multi-level interval setting also avoids the problem of loss of waterproof function due to single-point failure, greatly improving waterproof safety in complex rainy weather conditions.

[0111] In some alternative embodiments, the air guide 123 includes a first air guide section 1231, a second air guide section 1232, a third air guide section 1233, and a fourth air guide section 1234;

[0112] The first air guide section 1231 is provided with an air inlet 1241, the fourth air guide section 1234 is provided with an air outlet 1242, the second air guide section 1232 is connected to the end of the first air guide section 1231 away from the air inlet 1241, and the third air guide section 1233 is connected between the second air guide section 1232 and the fourth air guide section 1234.

[0113] The second air guide section 1232 is an arc-shaped section. The extension direction of the first air guide section 1231 matches the extension direction of the second air guide section 1232. The extension direction of the fourth air guide section 1234 has an angle with the extension direction of the first air guide section 1231.

[0114] The above technical solution has the following advantages or beneficial effects: the segmented air guide 123 structure enables the phased guidance of cold air, reducing turbulence and energy loss in airflow. The arc design of the second air guide section 1232 optimizes the airflow direction, and the transition connection of the third air guide section 1233 avoids abrupt changes in airflow, thereby improving the flow efficiency of cold air entering the cabin 112.

[0115] It should be noted that the arc-shaped section (second air guide section 1232) can smoothly change the direction of airflow, reduce flow resistance, and ensure air intake efficiency; while the fourth air guide section 1234 has an angle with the first air guide section 1231, which can guide the airflow to specific areas in the cabin that need to be cooled.

[0116] In some embodiments, the second guide section 1232 is designed as an arc-shaped section. The extension direction of the first guide section 1231 roughly matches the tangential direction of the starting end of the second guide section 1232, allowing the airflow to smoothly transition into the arc-shaped section. The extension direction of the fourth guide section 1234 forms an angle (e.g., downward tilt) with the extension direction of the first guide section 1231, which helps guide the airflow ultimately toward a specific area inside the cabin.

[0117] It should be noted that the first air guide section 1231 refers to the initial section of the air guide component 123 near the air inlet 1241, which is used to receive external cold air.

[0118] For example, the first air guide section 1231 is a straight section or an arc section with a rectangular cross-section.

[0119] It should be noted that the second air guide section 1232 refers to the middle section connecting the first air guide section 1231 and the third air guide section 1233, which is usually an arc-shaped structure.

[0120] For example, the second air guide section 1232 is an air guide section with an arc-shaped top.

[0121] It should be noted that the third air guide section 1233 refers to the transition section connecting the second air guide section 1232 and the fourth air guide section 1234.

[0122] For example, the straight section of the trapezoidal cross-section of the third air guide section 1233.

[0123] It should be noted that the fourth air guide section 1234 refers to the end section near the air outlet 1242, which is used to guide cold air to the cabin 112.

[0124] For example, the fourth air guide section 1234 is a straight or inclined section with a rectangular cross-section.

[0125] It should be noted that the first air guide section 1231 receives external cold air, the second air guide section 1232 guides airflow through an arc structure, the third air guide section 1233 serves as a transition section to smoothly connect the second air guide section 1232 and the fourth air guide section 1234, and the fourth air guide section 1234 finally introduces the cold air into the cabin 112.

[0126] In some embodiments, the connection between the air guide sections is achieved by fixed welding, snap-fitting or screw connection, or it can be an integrally formed structural component. The specific form can be adjusted according to actual needs.

[0127] In some embodiments, the cross-sectional area of ​​the first air guide section 1231 to the fourth air guide section 1234 gradually decreases along the direction from the air inlet 1241 to the air outlet 1242.

[0128] The cross-sectional area of ​​the first air guide section 1231 is larger than that of the fourth air guide section 1234. As the cold air flows, it is accelerated due to the reduced cross-sectional area, thereby increasing the velocity and kinetic energy of the air entering the nacelle 112. This structure optimizes airflow efficiency and reduces energy loss through fluid dynamics principles.

[0129] Furthermore, the tapered structure accelerates the flow of cold air, improving the efficiency of heat convection in the high-temperature areas of the cabin, while reducing the retention of rainwater in the air duct 124, thus indirectly enhancing waterproof performance.

[0130] In some alternative embodiments, the first rain shield 121 is disposed on the bottom wall of the second air guide section 1232 and has a first gap between it and the top wall of the second air guide section 1232.

[0131] The second rain shield 122 is located on the top wall of the fourth air guide section 1234 and has a second gap with the bottom wall of the fourth air guide section 1234. The second rain shield 122 is located at the air outlet 1242.

[0132] The above technical solution has the following advantages or beneficial effects: it achieves layered rainwater blocking through multi-level rainproof components, while preserving the flow path of cold air, thus balancing waterproof performance and heat dissipation efficiency.

[0133] In some embodiments, the first rain shield 121 is disposed on the bottom wall of the second air guide section 1232, and the second rain shield 122 is disposed on the top wall of the fourth air guide section 1234. The two are arranged at intervals along the extending direction of the air guide section 123, thus blocking rainwater through layering. Cold air flows in the interval area, avoiding the impact on heat dissipation efficiency due to the complete sealing of the rain shield.

[0134] In some embodiments, the first rain shield 121 is disposed on the bottom wall of the second air guide section 1232 and extends upward, but a first gap is maintained between its top end and the top wall of the second air guide section 1232 for air to pass through. The second rain shield 122 is disposed on the top wall of the fourth air guide section 1234 and extends downward, with a second gap maintained between its bottom end and the bottom wall of the fourth air guide section 1234 for air to pass through, and the second rain shield 122 is preferably located near the air outlet 1242.

[0135] In some alternative embodiments, the air guide assembly 120 further includes a water guide box 125 disposed on the fourth air guide section 1234, and the second rain shield 122 is configured to be located on the water guide box 125 to guide liquid in the air guide channel 124 into the water guide box 125.

[0136] The above technical solution has the following advantages or beneficial effects: the connection design between the second rain shield 122 and the water guide box 125 avoids short circuit problems caused by rainwater splashing onto electronic components.

[0137] Specifically, the second rain shield 122 is located at the air outlet 1242 of the fourth air guide section 1234. After the rainwater hits the rain shield, it is guided along its surface to the water guide box 125, and then flows through the water guide box 125 to the left and right sides of the cabin 112, so as to avoid directly splashing onto the electronic components.

[0138] It should be noted that even if a small amount of rainwater breaches the first line of defense and enters the rear of the channel, it will be intercepted by the second rain deflector 122 located near the air outlet 1242 and guided into the water guide box 125. The water guide box 125 can guide the collected water to the preset drainage path of the water guide box 125, preventing it from splashing directly onto the electronic components.

[0139] It should be noted that the water guide box 125 refers to a container structure used for collecting and guiding liquids.

[0140] For example, a recessed or box-shaped structure is provided at the end of the air guide channel 124.

[0141] It should be noted that when the vehicle is running, cold air enters the air guide channel 124 of the air guide component 123 through the first air intake 111 at the front of the hood body 110. The cold air enters along the first air guide section 1231, is guided by the second air guide section 1232, enters the fourth air guide section 1234 through the third air guide section 1233, and finally enters the engine compartment 112 through the air outlet 1242.

[0142] When driving in the rain, raindrops may enter the first air guide section 1231 with the airflow. Firstly, at the second air guide section 1232, due to the change in channel direction generating centrifugal force, some larger raindrops are thrown to the outside of the channel (top wall) and blocked head-on by the first rain deflector 121 located on the bottom wall. Even if some fine water mist or water droplets bypass the first rain deflector 121 and continue forward, they will be intercepted again by the second rain deflector 122 located on the top wall of the fourth air guide section 1234 before reaching the air outlet 1242. The liquid captured by the second rain deflector 122 is guided to the water guide box 125 below it and discharged through the drainage system. Clean air continues to flow through the first and second gaps, completing the heat dissipation function.

[0143] In some alternative embodiments, at least one of the first rain shield 121 and the second rain shield 122 is a baffle.

[0144] The above technical solution has the following advantages or beneficial effects: limiting the rain shield to a baffle form emphasizes the simplicity, reliability, and economy of the structure. The baffle structure is simple, easy to manufacture and process, and inexpensive; it is convenient to install and easy to fix to the inner wall of the air guide 123; its flat or specially shaped surface can effectively block and guide liquid, and its performance is reliable.

[0145] The vehicle hood assembly provided in this application includes: a hood body having a first air inlet, the hood body forming a hood compartment; and an air guide assembly disposed on the hood body, the air guide assembly including an air guide component having an air guide channel having a communicating air inlet and an air outlet; the air inlet being connected to the first air inlet, and the air outlet being connected to the hood compartment, so as to allow air from outside the vehicle to enter the hood compartment.

[0146] By combining an independent air guide with the first air intake, external cold air is directly introduced into the cabin, avoiding interference from high-temperature air, significantly reducing the temperature of key components in the cabin, and improving thermal management efficiency.

[0147] In addition, this application also provides a vehicle including the vehicle hood assembly 100 described above.

[0148] It should be noted that the specific structure of the vehicle hood assembly 100 is not limited here, but can be referred to the above.

[0149] Thanks to the aforementioned hood assembly, the vehicle can achieve better engine compartment thermal management and higher component environmental reliability under various operating conditions, especially at low speeds and in rainy weather.
