Detailed Implementation

[0020] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0021] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0022] refer to Figures 1 to 6This application provides a hood assembly 100. The hood assembly 100 includes a hood trim 1, an inner panel 2, and an outer panel 3. The inner panel 2 and the outer panel 3 are distributed and connected along the height direction. When the hood assembly 100 is assembled into a vehicle, the outer panel 3 can be understood as an exterior trim component of the vehicle, while the inner panel 2 serves as an interior trim component. When the hood assembly 100 closes the vehicle's engine compartment, occupants can only observe the outer panel 3 from the outside. When the hood assembly 100 is exposed in the engine compartment, occupants can observe the inner panel 2 from the outside of the vehicle. The outer panel 3 includes a mating hole 31, in which the hood trim 1 is located, thereby improving the aesthetics of the hood assembly 100.

[0023] The following section will provide a detailed description of the hood trim 1, the inner panel 2, and the outer panel 3 that mate with the hood trim 1. For the sake of brevity, this application sets the height, width, and length directions as reference directions, and these directions are perpendicular to each other. The accompanying drawings in the specification divide the height direction into upper (Tp) and lower (Bt), the width direction into left (Lf) and right (Rt), and the length direction into front (Fr) and rear (Bc) to more clearly and concisely illustrate the orientations, but this should not be construed as restrictive. Furthermore, it should be noted that front (Fr) and rear (Bc) can correspond to the front and rear of the vehicle, left (Lf) and right (Rt) correspond to the left and right sides when a person is facing the front of the vehicle, and upper (Tp) and lower (Bt) correspond to the roof and underside of the vehicle.

[0024] The hood trim 1 of this application includes an exterior trim panel 11 and an interior trim panel 12. The exterior trim panel 11 includes an exterior surface 111 and a connecting surface 112 disposed opposite each other along the height direction. The exterior trim panel 11 is connected to the outer panel 3 of the hood assembly 100, and the exterior surface 111 can be exposed through a mating hole 31 in the hood assembly 100, thereby achieving the decoration of the outer panel 3. The interior trim panel 12 is connected to the connecting surface 112. The interior trim panel 12 includes a connecting portion 121. The connecting portion 121 is connected to the mating portion 21 of the inner panel 2.

[0025] Compared to embodiments where the hood trim 1 is a single integrated structure, this application improves the overall structural strength of the hood trim 1 by setting it as a separate outer trim panel 11 and inner trim panel 12, thereby reducing deformation during processing and assembly and ensuring appearance quality. The increased structural strength of the hood trim 1 allows it to have a larger dimension in the width direction, enhancing its visual presence on the outer panel 3. When an air intake is machined on the hood trim 1, the larger dimension in the width direction improves the vehicle's air intake efficiency and off-road performance. Furthermore, connecting the inner trim panel 12 to the inner panel 2 further increases the connection strength compared to connecting via the outer panel 3.

[0026] For vehicles such as SUVs that are larger in width, the hood trim 1 also needs to be larger in width. The double-layered design of the interior panel 12 and the exterior panel 11 of the hood trim 1 in this application allows the hood trim 1 to maintain its structural strength while increasing its size, thereby meeting the strength requirements of the hood assembly 100 for larger vehicles and preventing easy deformation in collisions.

[0027] Optionally, the width dimension of the hood trim 1 is greater than or equal to 600 mm and less than or equal to 800 mm. For example, the width dimension of the hood trim 1 is any value between 600 mm, 610 mm, 620 mm, 630 mm, 640 mm, 650 mm, 660 mm, 670 mm, 680 mm, 690 mm, 700 mm, 710 mm, 720 mm, 730 mm, 740 mm, 750 mm, 760 mm, 770 mm, 780 mm, 790 mm, and 800 mm. A hood trim 1 with a small width dimension should be able to meet the structural strength requirements with a single-layer structure. A hood trim 1 with a large width dimension will occupy too much area on the outer panel 3, which may reduce the strength of the hood assembly 100. The dimensions of the hood trim 1 in this embodiment ensure that the arrangement of the exterior trim panel 11 and the interior trim panel 12 can balance cost and strength requirements, while not excessively occupying the area of ​​the exterior panel 3 and affecting the structural strength of the exterior panel 3.

[0028] To achieve the positioning of the hood trim 1, the dimensions of the mating hole 31 and the hood trim 1 must be matched. However, the width dimensions of the hood assembly 100 vary between different vehicle models and sizes. To meet the structural strength requirements of the hood assembly 100, the mating hole 31 can optionally extend along the width direction, and the ratio of the extension length of the mating hole 31 in the width direction to the extension length of the hood assembly 100 in the width direction is greater than or equal to 0.4 and less than or equal to 0.6. For example, the ratio can be any value between 0.40, 0.42, 0.44, 0.46, 0.48, 0.50, 0.52, 0.54, 0.56, 0.58, and 0.60. A mating hole 31 with a ratio that is too small will reduce the strength requirements of the hood trim 1 it fits. A mating hole 31 with a ratio that is too large will reduce the structural strength of the outer panel 3. The ratio within this range ensures the structural strength of the hood assembly 100, while allowing the hood trim 1 to balance structural strength and processing costs.

[0029] In some alternative embodiments, the outer panel 3 and the hood trim 1 are also connected, for example, the outer panel 3 is provided with a perforated structure for fastening by fasteners.

[0030] In some other alternative embodiments, such as Figure 2As shown, the outer panel 3 includes a flange 32 extending toward the inner panel 2 along its height direction. The flange 32 surrounds a mating hole 31 forming the outer panel 3. The end of the flange 32 abuts against the hood trim 1. In this embodiment, the flange 32 does not have a hole structure, but only abuts against the hood trim 1. Since the mating part 21 of the inner panel 2 and the connecting part 121 of the interior trim panel 12 are connected, the position of the hood trim 1 can actually be fixed. At this time, the flange 32 can only serve as a limiting function, and not a fixing function. With this setting, the processing steps of the mating hole 31 can be reduced. When processing the mating hole 31 on the outer panel 3, only drawing, trimming and shaping are required at the processing position of the mating hole 31, without the need to add a punching process after shaping. Thus, the processing of the outer panel 3 in this embodiment does not require further mold design for the punching process, thereby improving production efficiency and reducing production costs by reducing the number of processes. Furthermore, the outer panel 3 and the hood trim 1 do not need to be fixed together, so the hood trim 1 can be further designed not to protrude from the surface of the outer panel 3, thereby avoiding the increase in wind resistance of the vehicle caused by the setting of the hood trim 1.

[0031] The flange 32 may extend only along the height direction. In this case, when the hood assembly is accommodated in the mating hole 31, the projections of the outer trim panel 11 and the flange 32 in the height direction may not overlap. Alternatively, the flange 32 may have a portion extending towards the mating hole 31 in the width or length direction. In this case, there may be a gap between the outer trim panel 11 and the outer panel 3 in the height direction. Since the interior trim panel 12 and the inner panel 2 are already connected, i.e., the height direction is limited, this embodiment can reduce the fitting accuracy requirements of the outer trim panel 11 and the outer panel 3, avoiding interference that would prevent assembly. At the same time, since the outer panel 3 does not require machining of hole structures and is connected to the outer trim panel 11 by fasteners, the outer panel 3 allows for a certain distance between the outer trim panel 11 and it in the height direction without direct bonding.

[0032] To prevent dust, rainwater, and other impurities from entering the space between the inner panel 2 and the outer panel 3 through the gap between the hood trim 1 and the wall of the mating hole 31 during vehicle operation, in an optional embodiment, the hood trim 1 further includes a sealing strip 13. The sealing strip 13 surrounds the outer periphery of the outer panel 11 and connects to the outer panel 11. The sealing strip 13 is disposed on one side of the connecting surface 112 and is sealed to the outer panel 3. In this way, impurities can be blocked by the sealing strip 13 at the location of the outer panel 11, making it easier to remove impurities between the hood trim 1 and the wall of the mating hole 31 during subsequent exterior cleaning. Furthermore, in embodiments where the sealing strip 13 is disposed between the connecting surface 112 and the interior panel 12, the interior panel 12 and the outer panel 11 can jointly "clamp" the sealing strip 13, thereby effectively restricting the position of the sealing strip 13. In some alternative embodiments, the sealing strip 13 is directly molded onto the exterior trim panel 11 by injection molding, thereby eliminating the assembly process between the sealing strip 13 and the exterior trim panel 11 and further improving the connection strength between the sealing strip 13 and the exterior trim panel 11.

[0033] like Figure 2 As shown, optionally, the sealing strip 13 includes an engaging portion 131 and a sealing portion 132. The engaging portion 131 is fixedly connected to the connecting surface 112. The sealing portion 132 extends away from the outer trim panel 11 and extends in a direction away from the interior trim panel 12. The sealing portion 132 is sealed to the outer panel 3. When the hood trim 1 is assembled onto the outer panel 3, the hood trim 1 enters the mating hole 31 from the upper Tp towards the lower Bt. At this time, the end of the sealing portion 132 that contacts the engaging portion 131 is located at the lower Bt, and the end of the sealing portion 132 that is away from the engaging portion 131 is located at the upper Tp. Therefore, the extending direction of the sealing portion 132 can be adapted to the assembly direction of the hood trim 1, and the sealing portion 132 naturally deforms to form a seal with the wall of the mating hole 31. Therefore, the extension method of the sealing part 132 in this embodiment eliminates the need for assemblers to repeatedly move and adjust the posture of the sealing part 132 when assembling the hood trim 1. It also avoids the problem of the sealing part 132 bending during assembly due to mismatch between its extension direction and the assembly direction of the hood trim 1, which would affect the sealing performance.

[0034] In some alternative embodiments, the exterior trim panel 11 includes a first region 113 and a second end 1132. The first region 113 includes a first end 1131 and a second end 1132 disposed opposite to each other. The second end 1132 is connected to the second end 1131 and extends along the height direction toward a side away from the interior trim panel 12 to form a recessed region 115 of the exterior trim panel 11 on the exterior trim surface 111. (See attached...) Figure 2As shown, the interior trim panel 12 is located below the exterior trim panel 11 by Bt. Therefore, the second end 1132 extends along the direction from below Bt to above Tp, creating a recessed area 115 between the first area 113 and the second end 1132. This enhances the visual appeal of the hood assembly 100. Optionally, the second end 1132 may be provided with an air intake, allowing the hood trim 1 to function as an air intake trim to improve the vehicle's air intake efficiency.

[0035] Optionally, the exterior panel 11 also includes a third region 116. The third region 116 is connected to the end of the second end 1132 away from the second end 1132. The portion of the third region 116 near the second end 1132 extends in a direction from the second end 1132 toward the first end 1131. The portion of the third region 116 away from the second end 1132 extends in the height direction away from the first region 113. The third region 116 is connected to the outer panel 3. Thus, in the connection direction of the first region 113, the second end 1132, and the third region 116, the exterior panel 11 presents an arrangement that first extends from the front Fr to the rear Bc, then from the bottom Bt toward the top Tp, then from the rear Bc toward the front Fr, and finally from the bottom Bt toward the top Tp, thereby forming a shape as shown in the image. Figure 2 The cross-sectional shape shown.

[0036] This configuration allows the flange 32 of the outer panel 3 to extend only along the height direction at the point where it abuts against the third region 116, thus forming abutment with the portion of the third region 116 near the second end 1132, without requiring the flange 32 to extend in the length direction. Therefore, this embodiment reduces the processing difficulty of the flange 32, ensures a high yield rate, and lowers the precision requirements for the fit between the flange 32 and the outer trim panel 11.

[0037] In this embodiment, the first end 1131 is a straight end and can form a longitudinal contact with the flange 32. The third region 116 forms a longitudinal contact with the flange 32. Therefore, this embodiment avoids the problem of increased machining accuracy requirements in the longitudinal direction of the hood trim 1, where both the front (Fr) and rear (Bc) sides of the hood trim 1 contact the flange 32. Furthermore, the extension direction of the third region 116 allows the end of the third region 116 away from the second end 1132 to deform towards the recessed region 115. Therefore, when the hood trim 1 is assembled into the mating hole 31, the third region 116 has the deformation capacity to accommodate the flange 32 when the flange 32 interferes with its position in the longitudinal direction, thus enabling the assembly of the hood trim 1 without requiring further finishing of the hood trim 1 or the flange 32.

[0038] In embodiments where the hood trim 1 includes a sealing strip 13, the sealing strip 13 may be positioned to match the shape of the third region 116. For example... Figure 2 As shown, the fitting portion 131 fits into the portion of the third region 116 near the second end 1132, thus forming a shape extending along the forward Fr and rearward Bc directions on this cross section. The sealing portion 132 engages with the end of the third region 116 away from the second end 1132, thus extending in an orientation from the front Fr to the rear Bc. It should be noted that the exterior trim panel 11 and the interior trim panel 12 are connected along the height direction, with the exterior trim panel 11 located at the upper Tp and the interior trim panel 12 located at the lower Bt. Therefore, in this embodiment, the sealing portion 132 extends in a direction away from the interior trim panel 12, which should be understood as the sealing portion 132 extending from the lower Bt to the upper Tp.

[0039] The third region 116 is provided such that when the hood trim 1 is assembled in the mating hole 31, one side of the second end 1132 of the hood trim 1 first extends from the mating hole 31 into the gap between the inner panel 2 and the outer panel 3. The third region 116 abuts against the end of the flange 32 and causes the hood trim 1 to pivot around one side of the second end 1132, so that the first end 1131 can move close to the outer panel 3 and finally complete the assembly into the mating hole 31.

[0040] To achieve the pivoting limit of the hood trim 1, such as Figures 2 to 4 As shown, in an optional embodiment, the interior trim panel 12 includes a hook portion 122. The hook portion 122 includes a fixed unit 1221 and a free unit 1222 connected together. The fixed unit 1221 is connected to an end of the interior trim panel 12. The fixed unit 1221 extends along the height direction toward the side closer to the exterior trim panel 11. The end of the free unit 1222 away from the fixed unit 1221 extends in a direction from the second end 1132 toward the first end 1131. The gap between the end of the free unit 1222 and the third region 116 is used to accommodate the exterior panel 3.

[0041] In this embodiment, during assembly, the hood trim 1 is first engaged with the flange 32 in the gap between the free unit 1222 and the third region 116, allowing the end of the flange 32 to abut against the third region 116. Then, it is pivoted around the end of the flange 32, allowing the first end 1131 to move towards the outer panel 3 and be assembled into the mating hole 31. The hook portion 122 restricts the mating position between the third region 116 and the flange 32, enabling the hood trim 1 to be assembled into the mating hole 31 more quickly without needing to repeatedly adjust the abutting position of the flange 32 in the third region 116. This arrangement improves the assembly efficiency of the hood trim 1.

[0042] refer to Figure 4 and Figure 5Optionally, the connecting portion 121 protrudes towards the inner panel 2 to form an assembly space 14 for the hood trim 1 between the outer trim panel 11 and the interior panel 12. The side of the connecting portion 121 away from the interior panel 12 abuts against the inner panel 2. The connecting portion 121 is detachably connected to the inner panel 2. Compared to an embodiment where the connecting portion 121 and the interior panel 12 are essentially on the same plane, the protruding connecting portion 121 can reduce the mating area between the interior panel 12 and the inner panel 2, thereby reducing the processing accuracy requirements of the interior panel 12 and the inner panel 2. In addition, a larger proportion of the interior panel 12 can be positioned away from the inner panel 2, thereby approaching the outer trim panel 11 for mating, which improves the overall structural strength of the hood trim 1 and effectively controls the overall thickness of the interior panel 12 and the outer trim panel 11.

[0043] In the embodiment shown in the accompanying drawings, four connecting portions 121 are provided, spaced apart in the width direction. However, the number of connecting portions 121 shown in the drawings should be considered exemplary and not limiting. The number of connecting portions 121 can be increased or decreased. This application does not limit this.

[0044] The mating part 21 can be a hole opened only on the surface of the inner panel 2, thereby engaging with the connecting part 121. Alternatively, the mating part 21 can be recessed along the height direction towards the side away from the hood trim 1, and the connecting part 121 abuts against the mating part 21, connected by means of screws, pins, clips, welding, etc. The recessed mating part 21 engages with the connecting part 121 more intuitively, allowing workers or robots to more quickly locate the connection position of the connecting part 121 during assembly, avoiding the problem of adjusting the assembly position back and forth or even misassembly. In addition, the recessed mating part 21 can engage with the protruding connecting part 121, thereby preventing slippage and misalignment between the inner panel 2 and the interior trim panel 12, and improving the connection strength between the two.

[0045] Because the connecting portion 121 allows a larger interior trim panel 12 to fit against the exterior trim panel 11, in the embodiment shown in the drawings, the interior trim panel 12 has large welding portions 127 in multiple locations. The welding portions 127 provide welding points for the interior trim panel 12 and the exterior trim panel 11. Compared to a scheme where the interior trim panel 12 and the exterior trim panel 11 are only connected at their outer periphery, the welding portions 127 located inside the interior trim panel 12 can have a larger connection surface area 112, thereby improving the connection strength between the exterior trim panel 11 and the interior trim panel 12, and thus ensuring the overall structural strength of the hood trim 1.

[0046] Combination Figures 4 to 7Optionally, the interior trim panel 12 also includes a first positioning part 123. The first positioning part 123 is disposed on the side of the interior trim panel 12 away from the connecting surface 112 and protrudes away from the exterior trim panel 11 along the height direction. The first positioning part 123 is inserted into the positioning hole 22 of the interior panel 2. When connecting the interior panel 2 and the hood trim 1, the worker can first insert the first positioning part 123 into the positioning hole 22. At this time, the engagement of the positioning hole 22 makes it difficult for the hood trim 1 to move with a large stroke in the left Lf and right Rt directions, and also difficult to move with a large stroke in the front Fr and rear Bc directions. In this way, the connecting part 121 and the mating part 21 can be initially aligned. At this time, the worker or robot can more quickly and correctly connect the connecting part 121 and the mating part 21, which is beneficial to improving assembly efficiency.

[0047] Optionally, the interior panel 12 may further include a base portion 124. The base portion 124 is disposed on the side of the interior panel 12 away from the connecting surface 112. A first positioning portion 123 is disposed on the base portion 124. The cross-sectional area of ​​the base portion 124 perpendicular to the height direction is larger than the cross-sectional area of ​​the first positioning portion 123 perpendicular to the height direction. The base portion 124 reduces the overall size of the first positioning portion 123 in the height direction, thereby reducing the risk of breakage of the first positioning portion 123 under stress. Furthermore, when the first positioning portion 123 is subjected to stress, causing a bending moment at the connection point between the base portion 124 and the interior panel 12, the larger cross-sectional area of ​​the base portion 124 allows the connection point to withstand a larger bending moment, making breakage less likely. Therefore, the arrangement of the first positioning portion 123 and the base portion 124 in this embodiment improves the overall connection strength between the inner panel 2 and the interior panel 12.

[0048] In an optional embodiment, the hood assembly 100 further includes foam 4. Foam 4 is disposed around the first positioning portion 123. One end of foam 4 abuts against the interior trim panel 12 in the height direction, and the other end abuts against the inner panel 2. The cooperation between the first positioning portion 123 and the positioning hole 22 serves only a positioning function and does not require a strict fit; therefore, a large gap can exist between the walls of the first positioning portion 123 and the positioning hole 22. When water from outside the vehicle enters the space between the outer panel 3 and the inner panel 2 through the gap between the mating hole 31 and the hood trim 1, it can easily exit the inner panel 2 through the gap between the positioning hole 22 and the first positioning portion 123. If the user opens the hood assembly 100 from the outside of the vehicle to expose the engine compartment, water droplets or dried water stains accumulated on the inner panel 2 may cause discomfort to the user. This embodiment uses foam 4 to absorb water between the inner panel 2 and the outer panel 3, thereby improving the user experience. Furthermore, foam 4 also provides cushioning, preventing abnormal noises caused by rigid impacts between the interior trim panel 12 and the inner panel 2.

[0049] To improve the connection stability of the interior trim panel 12 and the inner panel 2 in the height direction, in some optional embodiments, the interior trim panel 12 further includes an abutment portion 126. The abutment portion 126 is disposed on the side of the interior trim panel 12 away from the connecting surface 112. The abutment portion 126 extends in the height direction and abuts against the inner panel 2. In this way, the hood trim 1 is not only connected to the inner panel 2 in the height direction through the connecting portion 121, but also can be supported in the height direction at a location other than the connecting portion 121 by the abutment portion 126. When the hood trim 1 is subjected to pressure from Tp above to Bt below, the joint support of the abutment portion 126 and the connecting portion 121 can prevent the hood trim 1 from breaking or being damaged. It can be seen that this embodiment can further ensure that the hood assembly 100 can meet the strength requirements when a larger hood trim 1 is provided.

[0050] Back Figure 2 In some optional embodiments, the interior trim panel 12 further includes a second positioning portion 125. The second positioning portion 125 is disposed at the end of the interior trim panel 12. The second positioning portion 125 abuts against the flange portion 32. The provision of the second positioning portion 125 can limit the gap between the hood trim 1 and the mating hole 31 in the length direction or the width direction. For example, if the second positioning portion 125 is disposed at the end of the hood trim 1 on the front Fr side, then the gap between the hood trim 1 on the front Fr side and the flange portion 32 can be prevented from being too small, thus avoiding an excessively large gap between the rear Bc side and the flange portion 32. At the same time, the provision of the second positioning portion 125 can also prevent the hood trim 1 from becoming loose in the mating hole 31 and causing abnormal noise when the connection between the interior trim panel 12 and the inner panel 2 becomes loose.

[0051] Back Figure 4 The interior trim panel 12 and the exterior trim panel 11 have similar outer contours for mating. During assembly, the interior trim panel 12 and the exterior trim panel 11 can be easily aligned by matching their outer contours. However, the exterior trim panel 11 may further include an alignment protrusion 117 disposed on the connecting surface 112. The interior trim panel 12 includes an alignment hole 128 extending through it in the height direction. The alignment protrusion 117 can be inserted into the alignment hole 128 to achieve assembly positioning of the interior trim panel 12 and the exterior trim panel 11, as well as displacement of the plane perpendicular to the height direction.

[0052] Weight-reducing holes 129 can be provided at various locations on the interior panel 12, such as in areas without connecting parts 121 or alignment holes 128. These weight-reducing holes 129 can reduce the overall weight of the interior panel 12 and prevent stress concentration and low processing accuracy caused by material buildup in localized areas. This application does not limit the specific location, number, or shape of the weight-reducing holes 129. Those skilled in the art can place the weight-reducing holes 129 at various locations on the interior panel 12 as needed, ensuring they avoid interference with other structures.

[0053] As mentioned earlier, dust and water may enter the assembly space 14 through the gap between the hood trim 1 and the mating hole 31, and then exit the assembly space 14 through the perforated structure of the inner panel 2. The sealing strip 13 effectively prevents impurities from entering the assembly space 14. However, due to aging of the sealing strip 13 or the influence of temperature, there is still a certain probability that sewage will enter the assembly space 14. On the side of the inner panel 2 away from the outer panel 3, a water-absorbing component is usually installed. After the water-absorbing component is soaked with dust and water and dries, residual stains may remain, resulting in a dirty visual effect.

[0054] To address this issue, in some alternative embodiments, the hood assembly 100 also includes a drainage structure to discharge fluid entering the assembly space 14 via the gap between the hood trim 1 and the mating hole 31 along a predetermined path, preventing fluid from wetting the absorbent component. It should be noted that in embodiments with both a sealing strip 13 and a drainage structure, the drainage structure does not imply that the sealing strip 13 cannot provide a good seal. In this embodiment, the drainage structure can be understood as a further measure to prevent wastewater from contaminating the absorbent component, particularly for embodiments where the flange 32 does not have a perforated structure for connection with the hood trim 1, rather than a solution contradicting the sealing strip 13.

[0055] refer to Figure 6 and Figure 7 The inner plate 2 includes a connecting area 23a ( Figure 7(As shown by the red dashed line) and a drain groove 24. The connecting area 23a is provided with a mating part 21, which should be understood as the area where the hood trim 1 is connected. The drain groove 24 is provided in the connecting area 23a and is recessed in the height direction relative to the mating part 21. In other words, in the height direction, the mating part 21 is located above the drain groove 24 (Tp), while the drain groove 24 is located below the mating part 21 (Bt). The drain groove 24 includes a high side 241 near the mating part 21 and a low side 242 away from the mating part 21. The bottom surface of the drain groove 24 is inclined so that the low side 242 is located away from the mating part 21 in the height direction relative to the high side 241. Since the mating part 21 is connected to the hood trim 1, in the height direction, the projection of the hood trim 1 is located within the connecting area 23a and at the location of the mating part 21. When fluid flows into the assembly space 14 through the gap between the hood trim 1 and the mating hole 31, the fluid can remain at the location of the mating part 21. Since the mating part 21 is located at a higher position, the fluid tends to flow towards the drainage channel 24 under the influence of gravity. Fluid entering the drainage channel 24 tends to flow from the higher side 241 to the lower side 242 within the inclined drainage channel 24. Thus, the drainage channel 24 can guide the fluid flow away from the mating part 21, preventing the fluid from leaving the assembly space 14 through the perforated structure of the mating part 21.

[0056] Optionally, at least a portion of the hood trim 1 is projected in the height direction into the drainage groove 24. For example... Figure 7 As shown, the edge of the hood trim 1 located at the front Fr can be positioned behind the lower edge 242 at Bc, allowing fluid flowing in through the gap between the end of the hood trim 1 near the front Fr and the mating hole 31 to drip directly into the drain groove 24, thus flowing into the drainage path. Alternatively, the edge of the hood trim 1 located at the left Lf can also be positioned near the right Rt relative to the edge of the drain groove 24, allowing fluid flowing in through the gap between the end of the hood trim 1 near the left Lf and the mating hole 31 to drip directly into the drain groove 24. Of course, the edges of the hood trim 1 at the rear Bc and right Rt can also be projected into the drain groove 24, allowing fluid to drip directly into the drain groove 24.

[0057] like Figure 7 As shown, in an optional embodiment, the mating portions 21 include multiple portions, which are spaced apart along the width direction. To ensure drainage as close as possible to the rear Bc of the connecting area 23a, a portion of the drainage groove 24 is disposed between two adjacent mating portions 21 along the width direction. Thus, the drainage groove 24 and the mating portions 21 are spaced apart in the width direction, allowing the higher side 241 to be positioned as close as possible to the edge of the connecting area 23a to the rear Bc, achieving effective drainage.

[0058] Optionally, the recessed depth of the drainage channel 24 in the height direction is greater than or equal to 0.5 mm and less than or equal to 3 mm. For example, the recessed depth of the drainage channel 24 can be any value between 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2.0 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, and 3.0 mm. If the recessed depth of the drainage channel 24 is too small, the water storage capacity and the adjustable slope will be too small. If the recessed depth of the drainage channel 24 is too large, fluid will easily remain in the drainage channel 24, and it will also affect the dimensions of the inner plate 2 in the height direction. The recessed depth of the drainage groove 24 within this range enables the drainage groove 24 to have a better drainage slope, while optimizing the dimensions of the inner panel 2.

[0059] The inner panel 2 includes a front end portion 25. The front end portion 25 should be understood as the end of the inner panel 2 near the front of the vehicle. In some alternative embodiments, the front end portion 25 is located on the side of the drain groove 24 away from the mating portion 21. The front end portion 25 is located away from the mating portion 21 in the height direction relative to the lower side 242. That is, the mating portion 21, the drain groove 24, and the front end portion 25 are arranged sequentially in the direction from rear Bc to front Fr and from upper Tp to lower Bt. Therefore, when fluid flows into the assembly space 14 through the gap between the hood trim 1 and the mating hole 31, the fluid tends to flow along the direction of the mating portion 21, the drain groove 24, and the front end portion 25 under the influence of gravity, i.e., it tends to flow from rear Bc to front Fr.

[0060] To allow residual fluid in the assembly space 14 to drain out, the inner panel 2 in this embodiment also includes a drain hole 26 located at the front end 25. The drain hole 26 extends through the inner panel 2 along its height. Fluid entering the drain channel 24 tends to flow towards the front end 25. Fluid reaching the front end 25 can then exit the assembly space 14 through the drain hole 26. This arrangement avoids problems such as rust and dirt accumulation caused by fluid residue in the assembly space 14. Furthermore, the volume of fluid entering the assembly space 14 through the hood trim 1 and the wall of the mating hole 31 is small, so the fluid entering the cabin through the drain hole 26 will not cause operational problems for the cabin components.

[0061] Optionally, the drainage channel 24 may further include a water guide channel 243 disposed on the lower side 242. The water guide channel 243 extends in a direction away from the mating portion 21. The water guide channel 243 can further guide the fluid in the drainage channel 24 to flow toward the lower side 242. In embodiments where the front end portion 25 is disposed in the height direction away from the mating portion 21 relative to the lower side 242, the water guide channel 243 may extend along the connection region 23a to the front end portion 25, so that the fluid can flow toward the front end portion 25 under the action of the water guide channel 243, and then leave the assembly space 14 through the drainage hole 26.

[0062] To prevent fluid from flowing freely due to vibrations during vehicle operation, in some optional embodiments, the inner panel 2 further includes a first water-blocking rib 27. The first water-blocking rib 27 is disposed in the connecting region 23a and on at least one side of the connecting region 23a in the width direction. The first water-blocking rib 27 extends along the connection direction between the lower side 242 and the higher side 241. Thus, when fluid in the drain channel 24 flows to the left (Lf) or right (Rt), it can be blocked by the first water-blocking rib 27, allowing the fluid to be held on one side of the drain channel 24 and then guided away through the drain channel 24.

[0063] The inner panel 2 includes a reinforcing region 23b disposed adjacent to the connecting region 23a. Figure 7 (As shown by the blue dashed line). The reinforcing region 23b is located near the high side 241. The inner plate 2 includes a support portion 29 disposed in the reinforcing region 23b. The support portion 29 protrudes relative to the mating portion 21 in the height direction. When the inner plate 2 is connected to the outer plate 3, the support portion 29 abuts against the surface of the outer plate 3 facing the assembly space 14, so that the outer plate 3 can withstand the force from the top Tp to the bottom Bt without deformation. In this embodiment, one end of the first water-blocking rib 27 can be connected to the support portion 29. Since the support portion 29 is located behind the high side 241 Bc, and the support portion 29 protrudes in the height direction, the fluid flowing towards the rear Bc via the drainage groove 24 can be blocked by the support portion 29. In this embodiment, one end of the first water-blocking rib 27 is connected to the support portion 29, so that the cooperation between the first water-blocking rib 27 and the support portion 29 can achieve the blocking of fluid in both the width and length directions. Thus, the inner panel 2 does not need to be equipped with a water-blocking rib located at the rear Bc for the drainage channel 24, thereby improving the space utilization of the inner panel 2.

[0064] In an optional embodiment, the inner plate 2 further includes a second water-blocking rib 28. The water-blocking rib is disposed at the front end 25. The second water-blocking rib 28 is connected along the extending directions of the lower side 242 and the higher side 241. Similar to the first water-blocking rib 27, the second water-blocking rib 28 can also prevent the fluid from flowing randomly in the width direction, allowing the fluid to flow forward along the height difference Fr. It should be noted that the connection of the first water-blocking rib 27 and the second water-blocking rib 28 along the extending directions of the lower side 242 and the higher side 241 should be understood as having a certain projection in the length direction, rather than extending strictly along the length direction.

[0065] In an embodiment where the interior panel 12 has a first positioning part 123, the positioning hole 22 can be located in the drain groove 24, thereby effectively utilizing the space of the connection area 23a. Furthermore, in an embodiment where foam 4 is provided around the outer periphery of the first positioning part 123, the foam 4, by sealing the gap between the hood trim 1 and the inner panel 2, can also absorb fluid overflowing from the drain groove 24, preventing fluid from flowing out through the positioning hole 22 and affecting the appearance of the absorbent component Bt below the connection area 23a.
