Abstract
Description
Technical Field
[0001] This disclosure relates to the field of vehicle technology, and more specifically, to a front compartment assembly and a vehicle. Background Technology
[0002] In related technologies, when a vehicle is traveling at high speed, the airflow outside the hood is fast and the air pressure is low. Some of the airflow will enter through the gap between the hood and the vehicle body, causing the pressure of the incoming airflow to concentrate locally on the hood, making the hood prone to bending and breaking. Utility Model Content
[0003] The purpose of this disclosure is to provide a front compartment assembly and a vehicle that can improve the structural strength of the front compartment cover and prevent the rear cover of the front compartment cover from bending and breaking.
[0004] To achieve the above objectives, this disclosure provides a front compartment assembly, including a front compartment cover, a ventilation cover, and a sealing structure. The front compartment cover includes a rear cover that covers the ventilation cover and a front cover located on the front side of the ventilation cover. The sealing structure is disposed between the front compartment cover and the ventilation cover to seal the gap between the front compartment cover and the ventilation cover.
[0005] Through the above technical solution, during vehicle operation, such as at high speeds, high-speed airflow enters the front compartment. By installing a sealing structure to seal the gap between the front compartment cover and the ventilation cover, interference with the airflow at the ventilation cover can be reduced. This mitigates the risk of localized stress concentration and uneven stress caused by turbulent airflow at the ventilation cover, which could lead to a large air pressure difference at the rear cover, making it more susceptible to impact and potentially causing the rear cover or even the entire front compartment cover to bend and break. Therefore, by installing a sealing structure between the front compartment cover and the ventilation cover, the overall air pressure inside the front compartment can be kept stable, balancing the stress on the front compartment cover and reducing or even preventing the risk of bending and breakage of the rear cover or even the entire front compartment cover.
[0006] Furthermore, the sealed structure reduces vibration and aerodynamic noise caused by turbulence, improves NVH wind noise performance at the rear of the front compartment, reduces whistling, enhances dust protection at the rear cover, ensures stable and clean air intake for the air conditioning system at the ventilation cover, avoids uneven stress and resonance, protects structural performance, and improves the modal structure and stiffness of the rear end of the front cover inner panel. In addition, because the ventilation cover is located at the rear of the front compartment, it works in conjunction with the front compartment cover and the sealing structure to form an effective seal, thereby utilizing the vehicle's own structure to achieve a seal at the rear end of the front compartment interior.
[0007] In some possible implementations, the ventilation cover has a vent, and the sealing structure includes a first seal. The portion of the ventilation cover located in front of the vent is provided with the first seal between it and the front hatch cover. This prevents airflow from flowing towards the vent, thus avoiding interference with the orderly flow of air at the vent and preventing turbulent airflow.
[0008] In some possible implementations, the sealing structure includes second seals connected to both sides of the first seal, with the two second seals positioned far apart from each other from front to back. Thus, the second seals can guide airflow entering the front compartment to predetermined paths on both sides, allowing it to bypass the vents.
[0009] In some possible implementations, the thickness of the second seal is greater than the thickness of the first seal. Thus, the first and second seals can respectively adapt to the gaps on the front side and sides of the vent, ensuring an effective seal between the front hatch cover and the vent cover.
[0010] In some possible implementations, the front hatch cover is connected to a hinge, and the sealing structure further includes a third seal connected to the second seal. The third seal comprises a first section and a second section, the first section being located inside the hinge and the second section being located behind the hinge. Thus, the third seal avoids obstructing the hinge's movement area, preventing interference with the hinge's rotation, damage to the hinge's moving parts, and ensuring smooth opening and closing of the front hatch cover.
[0011] In some possible implementations, the second segment is positioned laterally, with the ends of the two second segments facing away from each other. This allows the second segment to guide airflow outwards from both sides of the vehicle body, thus facilitating the exhaust of air from the sides of the vehicle body into the front compartment and maintaining stable air pressure inside the front compartment.
[0012] In some possible implementations, the sealing structure is constructed as a sealing strip and includes a transition section that connects the first and second seals with a smooth transition. This avoids direct connection between the first and second seals, which could prevent the connection from fitting tightly against the surface of the front hatch or ventilation cover, creating gaps and affecting the sealing effect.
[0013] In some possible implementations, the sealing structure is snapped onto the front hatch cover and abuts against the ventilation cover. This ensures the stability of the snap-fit connection between the sealing structure and the front hatch cover, preventing the sealing structure from detaching or shifting due to vibration, thus affecting the sealing effect.
[0014] In some possible implementations, the third seal is also bonded to the front hatch cover. This allows for bonding of the third seal near the side gaps, achieving a dual fixation of snap-fit and bonding to enhance the securing effect of the third seal.
[0015] According to a second aspect of this disclosure, a vehicle is provided, including the front compartment assembly as described above.

[0025] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.
[0026] In this disclosure, unless otherwise stated, the directional terms "inner" and "outer" refer to "inner" and "outer" relative to the contour of the corresponding component itself. "Front" and "rear" refer to the attached... Figure 1 The front and back directions within. "Left" and "right" refer to the attached... Figure 1 The left and right directions are specified. Furthermore, the use of terms such as "first" and "second" is intended to distinguish different components and does not imply sequence or importance. Additionally, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings denote the same elements. Those skilled in the art should understand that the above definitions are for explanation and illustration only and should not be construed as limiting the present disclosure.
[0027] According to a specific embodiment of this disclosure, refer to Figures 1 to 5 As shown, a front compartment assembly is provided, including a front compartment cover 1, a ventilation cover 3 and a sealing structure 2. The front compartment cover 1 includes a rear cover 12 covering the ventilation cover 3 and a front cover 11 located in front of the ventilation cover 3. The sealing structure 2 is disposed between the front compartment cover 1 and the ventilation cover 3 to seal the gap between the front compartment cover 1 and the ventilation cover 3.
[0028] Through the above technical solution, during vehicle operation, for example, at high speeds, high-speed airflow will rush into the front compartment. By setting up the sealing structure 2, the gap between the front compartment cover 1 and the ventilation cover 3 is sealed, reducing interference with the airflow at the ventilation cover 3. This reduces the risk of localized stress concentration and uneven stress caused by turbulent airflow at the ventilation cover 3, which could lead to a large air pressure difference at the rear cover 12, making it susceptible to impact and causing the rear cover 12 or even the entire front compartment cover 1 to bend and break. Therefore, by setting up the sealing structure 2 in the gap between the front compartment cover 1 and the ventilation cover 3, the overall air pressure inside the front compartment can be kept stable, the stress on the front compartment cover 1 can be balanced, and the risk of bending and breaking of the rear cover 12 or even the entire front compartment cover 1 can be reduced or even avoided.
[0029] Furthermore, the sealing structure 2 reduces vibration and aerodynamic noise caused by turbulence, improves NVH wind noise performance at the rear of the front compartment, reduces howling, improves dustproof performance at the rear cover 12, ensures stable and clean air intake for the air conditioning system at the ventilation cover 3, avoids uneven stress and resonance, protects structural performance, and improves the modal structure and stiffness of the rear end of the inner front cover panel. In addition, since the ventilation cover 3 is located at the rear of the front compartment, it can form an effective seal with the front cover 1 and the sealing structure 2, thereby utilizing the vehicle's own structure to achieve a seal at the rear end of the front compartment. This can be achieved at speeds exceeding 120 km / h, for example, 340 km / h to 350 km / h.
[0030] In some embodiments of this disclosure, reference is made to Figure 1 As shown, the ventilation cover 3 has a ventilation opening 31, and the sealing structure 2 includes a first sealing element 21. The portion of the ventilation cover 3 located in front of the ventilation opening 31 is provided with the first sealing element 21 between it and the front cabin cover 1. In this way, the first sealing element 21 can seal the gap between the ventilation cover 3 and the front cabin cover 1 in front of the ventilation opening 31, which can prevent the airflow entering the front cabin from flowing backward and then flowing towards the ventilation opening 31, interfering with the orderly flow of airflow at the ventilation opening 31, causing airflow turbulence, and impacting the rear cover 12 covering the ventilation cover 3, causing the rear cover 12 or even the front cabin cover 1 to bend and break.
[0031] In some embodiments of this disclosure, reference is made to Figure 1 As shown, the sealing structure 2 includes second seals 22. The first seal 21 has second seals 22 connected to both its left and right sides, with the two second seals 22 positioned far apart from each other from front to back. This allows the second seals 22 to seal the gaps between the ventilation cover 3 and the rear cover 12 on both sides of the vent 31, preventing airflow from entering the front compartment from the sides and flowing towards the vent 31. Simultaneously, by positioning the two second seals 22 far apart from each other from front to back, the second seals 22 can guide the airflow entering the front compartment to predetermined paths on both sides, thus allowing the airflow to bypass the vent 31. Therefore, the arrangement of the second seals 22 prevents the airflow entering the front compartment from interfering with the orderly flow of air at the vent 31, avoiding airflow turbulence.
[0032] In some embodiments of this disclosure, reference is made to Figures 2 to 5 As shown, the thickness of the second seal 22 can be greater than the thickness of the first seal 21. Due to the arc-shaped structure of the ventilation cover 3 and the front hatch cover 1, the gap between the front hatch cover 1 and the ventilation cover 3 is narrower at the front of the ventilation opening 31, and wider on both sides of the ventilation opening 31. By setting the thickness of the second seal 22 to be greater than the thickness of the first seal 21, the first seal 21 and the second seal 22 can respectively adapt to the gaps at the front and sides of the ventilation opening 31, avoiding deformation of the front hatch cover 1 due to excessive thickness of the first seal 21 at the front of the ventilation opening 31, or ineffective sealing due to insufficient thickness of the second seal 22 on both sides of the ventilation opening 31. This ensures effective sealing of the gap between the front hatch cover 1 and the ventilation cover 3.
[0033] The thickness of the first seal 21 is Figure 2 and Figure 4 The length of H1 and the thickness of the second seal 22 are... Figure 3 and Figure 5 The length of H2 in the equation.
[0034] In some embodiments of this disclosure, reference is made to Figure 1 As shown, the front hatch cover 1 is connected to a hinge 10. The sealing structure 2 also includes a third seal 23 connected to the second seal 22. The third seal 23 includes a first section 231 and a second section 232. The first section 231 is located inside the hinge 10, and the second section 232 is located behind the hinge 10. In this way, the third seal 23 can extend from the inside of the hinge 10 to the rear of the hinge 10 to fully seal the gaps on both sides of the vent 31 and prevent airflow from entering. At the same time, the arrangement of the third seal 23 can avoid the moving area of the hinge 10, avoid interference with the rotation of the hinge 10, avoid damage to the moving parts of the hinge 10, and avoid affecting the smoothness and functionality of the opening and closing of the front hatch cover 1. Furthermore, it avoids contact or friction between the third seal 23 and the components of the hinge 10, which would cause wear and tear on the third seal 23 and affect its service life.
[0035] In some embodiments of this disclosure, reference is made to Figure 1 As shown, the second segment 232 runs along the left-right direction, with the ends of the two second segments 232 facing away from each other. This creates airflow channels on both sides of the front compartment, guiding the airflow outwards through the second segment 232. This allows the airflow to exit the front compartment from both sides of the vehicle body, preventing airflow accumulation or backflow and helping to maintain stable air pressure inside the front compartment. Simultaneously, it prevents airflow turbulence behind the hinge 10, avoiding high-frequency vibrations from impacting the sheet metal surface and exacerbating wind noise.
[0036] In some embodiments of this disclosure, reference is made to Figure 1 As shown, the sealing structure 2 is constructed as a sealing strip and includes a transition section 24. The transition section 24 connects the first sealing element 21 and the second sealing element 22 with a smooth transition. This allows the first sealing element 21 and the second sealing element 22 to be connected via the transition section 24, avoiding the situation where a direct connection due to the difference in thickness between the first sealing element 21 and the second sealing element 22 would result in a gap between the connection point and the surface of the front hatch cover 1 or ventilation cover 3, affecting the sealing effect. Simultaneously, the smooth transition of the curved surface disperses stress, preventing localized damage and extending the fatigue life of the sealing strip.
[0037] The first seal 21 and the second seal 22 are constructed as straight sections and can be formed by extrusion molding, while the third seal 23 and the transition section 24 are constructed as curved sections and can be formed by injection molding. Alternatively, the first seal 21, the second seal 22, the third seal 23 and the transition section 24 can all be formed by injection molding. This disclosure does not impose any specific limitations on this.
[0038] In some embodiments of this disclosure, reference is made to Figures 2 to 5As shown, the sealing structure 2 is snapped onto the front hatch cover 1 and abuts against the ventilation cover 3. This ensures the reliability of the connection between the sealing structure 2 and the front hatch cover 1, preventing the sealing structure 2 from falling off or shifting due to vibration, thus affecting the sealing effect. The sealing structure 2 can be constructed as a sealing strip, which can be snapped onto the inner sheet metal of the front hatch cover 1 using multiple clips 25. The structure is simple, easy to install, and convenient for disassembly and replacement.
[0039] In some embodiments of this disclosure, the third seal 23 is also bonded to the front hatch cover 1. This provides a dual fixation of the third seal 23 near the side gaps through both snap-fit and adhesive bonding, enhancing the fixation effect and preventing displacement of the end of the third seal 23 during the opening and closing of the front hatch cover 1, which could affect the sealing performance. 3M tape can be used for bonding; the tape coverage length can be 20mm to 50mm, and the width can be 5mm to 10mm, without specific limitations in this disclosure.
[0040] According to a second aspect of this disclosure, a vehicle is provided, including the front compartment assembly as described above. The vehicle has all the beneficial effects of the aforementioned front compartment assembly, which will not be elaborated upon herein.
[0041] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.
[0042] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.
[0043] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
