Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to the inner panel of a car door, the door assembly, and the vehicle. Background Technology

[0002] The lower part of the inner tailgate panel usually has a tailgate drain hole. During the tailgate assembly painting process, the paint electrophoresis liquid in the cavity formed between the inner and outer tailgate panels can be drained through the tailgate drain hole to prevent residual paint electrophoresis liquid from contaminating the next electrophoresis pool, and to effectively improve the painting quality of the tailgate assembly. During normal vehicle operation, the liquid accumulated in the cavity can be drained through the tailgate drain hole.

[0003] Currently, while existing tailgate drain holes can achieve leakage, their size is large. If existing plugs with connecting holes are used to seal the tailgate drain holes, leakage can still occur through the connecting holes when the plug is in the sealed state. However, the cost of machining connecting holes on the plug is high, and the diameter of the connecting holes is limited. If the tailgate drain holes are not sealed, especially during vehicle operation, the large size of the drain holes will increase cabin noise and affect the overall vehicle comfort. Utility Model Content

[0004] The purpose of this utility model is to provide a door inner panel, a door assembly, and a vehicle to solve the aforementioned problems existing in the tailgate inner panel of the prior art.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] The inner door panel includes:

[0007] The inner plate body has a through first leakage hole at the bottom along its height direction. The first leakage hole includes a first sub-hole and a second sub-hole that are connected to each other.

[0008] The first sealing element blocks the first sub-hole, and the second sub-hole at least partially connects to both sides of the inner plate body along its own thickness direction.

[0009] As an alternative to the aforementioned door inner panel, the flow cross-sectional area of ​​the first sub-hole is larger than the flow cross-sectional area of ​​the second sub-hole.

[0010] And / or, along the height direction of the inner plate body, the first sub-hole is located above the second sub-hole;

[0011] And / or, along the width direction of the inner plate body, the second sub-hole is located between the two ends of the first sub-hole.

[0012] As an alternative to the aforementioned door inner panel, the inner panel body includes a main body and a guide portion connected together. The guide portion is located at the bottom of the main body along the height direction of the inner panel body, and the first leakage hole is disposed in the guide portion.

[0013] As an alternative to the aforementioned door inner panel, the first sub-hole is cylindrical;

[0014] And / or, the second sub-hole is rectangular in shape.

[0015] As an alternative to the aforementioned door inner panel, the flow cross-section of the first sub-hole is circular, and the radius of the circle ranges from 5mm to 8mm.

[0016] As an alternative to the aforementioned door inner panel, the number of the first leakage holes is at least two, and the at least two first leakage holes are distributed at intervals along the width direction of the inner panel body.

[0017] As an alternative to the aforementioned door inner panel, the first sealing member also partially blocks the second sub-hole.

[0018] As an alternative solution for the aforementioned door inner panel, the area of ​​the first sealing member blocking the second sub-hole is the first area, and the flow cross-sectional area of ​​the second sub-hole that is not blocked is the second area, wherein the first area is greater than the second area;

[0019] And / or, the portion of the second sub-hole near the first sub-hole is blocked by the first sealing element.

[0020] The door assembly includes an outer door panel and the aforementioned inner door panel, with a cavity formed between the outer door panel and the inner panel body, and the cavity communicating with the first leakage hole.

[0021] The vehicle includes the aforementioned door inner panel, or the aforementioned door assembly.

[0022] The beneficial effects of this utility model are:

[0023] This utility model provides an inner door panel, which includes an inner panel body and a first sealing member. The inner panel body has a through-hole at its bottom along its height direction; the first leakage hole includes a first sub-hole and a second sub-hole that are connected; the first sealing member seals the first sub-hole, and the second sub-hole at least partially connects to both sides of the inner panel body along its thickness direction.

[0024] By setting the first leakage hole to include a first sub-hole and a second sub-hole that are connected, during the painting process of the door assembly, the first sealing component is kept from blocking the first sub-hole, thereby maximizing the flow cross-sectional area of ​​the first leakage hole. This allows the liquid in the cavity formed between the inner panel body and the outer panel of the door to flow out through the first leakage hole quickly and efficiently.

[0025] During normal vehicle use, the first sealing component keeps the first sub-hole sealed, which reduces the flow cross-sectional area of ​​the first leakage hole, and the second sub-hole always allows the liquid in the cavity formed between the inner panel body and the outer door panel to flow out, while avoiding the need to process connecting holes on the first sealing component.

[0026] Based on the premise that the total flow cross-sectional area of ​​the first leakage hole remains unchanged, this setting can effectively alleviate the problem of increased cabin noise caused by not sealing the leakage hole, ensure that the liquid in the cavity formed between the inner panel body and the outer door panel can always flow out, avoid processing connecting holes on the first sealing part, and the inner door panel has a simple structure and is easy to process and manufacture.

[0027] This utility model also provides a door assembly, including an outer door panel and the aforementioned inner door panel. A cavity is formed between the outer and inner door panels, and the cavity communicates with a first leakage hole. By using the aforementioned inner door panel, compared with the prior art, it can effectively alleviate the problem of increased cabin noise caused by not sealing the leakage hole, ensure that the liquid in the cavity formed between the inner panel and the outer door panel can always flow out, and reduce the processing cost of the door assembly.

[0028] This utility model also provides a vehicle, including the aforementioned door inner panel, or including the aforementioned door assembly. By adopting the aforementioned door inner panel, the user comfort of the vehicle can be effectively improved. Attached Figure Description

[0043] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0044] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0045] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0046] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0047] This utility model provides an inner door panel, such as Figure 1-5 As shown, the inner panel of the car door includes an inner panel body 1 and a first sealing member 2. The inner panel body 1 has a through first leakage hole 121 at its bottom along its height direction; the first leakage hole 121 includes a first sub-hole 1211 and a second sub-hole 1212 that are connected; the first sealing member 2 seals the first sub-hole 1211, and the second sub-hole 1212 is at least partially connected to both sides of the inner panel body 1 along its thickness direction.

[0048] By configuring the first drain hole 121 to include a first sub-hole 1211 and a second sub-hole 1212 that are connected, during the painting process of the door assembly, the first sealing member 2 is kept unblocked from the first sub-hole 1211, thereby maximizing the flow cross-sectional area of ​​the first drain hole 121. This allows the liquid in the cavity 4 formed between the inner panel body 1 and the outer door panel 3 to flow out quickly and efficiently through the first drain hole 121. Specifically, the manufacturing process of the door assembly includes the painting process of the door assembly.

[0049] During normal vehicle use, the first sealing member 2 keeps the first sub-hole 1211 blocked, which reduces the flow cross-sectional area of ​​the first leakage hole 121, and the second sub-hole 1212 always allows the liquid in the cavity 4 formed between the inner panel body 1 and the outer door panel 3 to flow out, and avoids the need to process connecting holes on the first sealing member 2.

[0050] Based on the premise that the total flow cross-sectional area of ​​the first leakage hole 121 remains unchanged, this setting can effectively alleviate the problem of increased cabin noise caused by not sealing the leakage hole, ensure that the liquid in the cavity 4 formed between the inner panel body 1 and the outer door panel 3 can always flow out, avoid processing connecting holes on the first sealing member 2, and the inner door panel has a simple structure and is easy to process and manufacture.

[0051] The flow cross-sectional area refers to the cross-sectional area of ​​a pipe or hole perpendicular to the direction of fluid flow, used to describe the size of the passage through which fluid passes. This cross-section must be perpendicular to the direction of fluid flow.

[0052] Optionally, in this embodiment, as Figure 1 As shown, the flow cross-sectional area of ​​the first sub-hole 1211 is larger than that of the second sub-hole 1212. This arrangement further alleviates the problem of increased cabin noise caused by not sealing the leakage holes in the prior art during normal vehicle operation.

[0053] In other embodiments, the flow cross-sectional area of ​​the first sub-hole 1211 may be equal to the flow cross-sectional area of ​​the second sub-hole 1212. In other embodiments, the flow cross-sectional area of ​​the first sub-hole 1211 may be smaller than the flow cross-sectional area of ​​the second sub-hole 1212.

[0054] Optionally, in this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, along the height direction of the inner panel body 1, the first sub-hole 1211 is located above the second sub-hole 1212. This ensures that during normal vehicle use, the second sub-hole 1212 can stably and efficiently allow the liquid in the chamber 4 to flow out, and effectively avoids the problem of residual liquid leakage in the chamber caused by sealing the leakage hole with a plug in the prior art; secondly, it can effectively reduce the space occupied by the first leakage hole 121 along the width direction of the inner panel body 1; and thirdly, it can improve the aesthetics of the inner panel body 1.

[0055] In other embodiments, the first sub-hole 1211 and the second sub-hole 1212 may be located in the same height region along the height direction of the inner plate body 1.

[0056] Specifically, for the tailgate assembly of the vehicle, which is applied to the inner door panel, the height direction of the inner panel body 1 is the height direction of the tailgate assembly when it is in the closed state.

[0057] Optionally, in this embodiment, as Figure 1 and Figure 2As shown, along the width direction of the inner panel body 1, the second sub-hole 1212 is located between the two ends of the first sub-hole 1211. This can further reduce the space occupied by the first leakage hole 121 along the width direction of the inner panel body 1, and further improve the aesthetics of the inner panel body 1. Preferably, along the width direction of the inner panel body 1, the second sub-hole 1212 is located in the middle region of the first sub-hole 1211, so as to further improve the aesthetics of the inner panel body 1.

[0058] In other embodiments, the second sub-hole 1212 may be located on one side of the first sub-hole 1211 along the width direction of the inner plate body 1.

[0059] In other embodiments, the second sub-hole 1212 may also include a first part, a second part and a third part, with the second part connecting the first part and the third part; along the width direction of the inner plate body 1, the first part is located on one side of the first sub-hole 1211 and the third part is located on the other side of the first sub-hole 1211.

[0060] Among them, such as Figure 2 , Figure 3 and Figure 5 As shown, the inner panel body 1 includes a main body 11.

[0061] Optionally, in this embodiment, as Figure 1-5 As shown, the inner plate body 1 also includes a flow guide 12 connected to the main body 11 and located at the bottom of the main body 11 along the height direction of the inner plate body 1. A first leakage hole 121 is provided on the flow guide 12. The flow guide 12 is used to guide the liquid in the chamber 4 to the first leakage hole 121.

[0062] By setting the first leakage hole 121 in the flow guide 12, which is located at the bottom of the main body 11 along the height direction of the inner panel body 1, the first leakage hole 121 is basically at the bottom of the chamber 4. The flow guide 12 can guide the liquid in the chamber 4 to the first leakage hole 121. Thus, during the painting process of the door assembly, the liquid in the chamber 4 can be made to flow out through the first leakage hole 121 more quickly and efficiently. During normal use of the vehicle, the liquid in the chamber 4 can be made to flow out through the second sub-hole 1212 more stably and efficiently.

[0063] Further, optionally, in this embodiment, such as Figure 4 and Figure 5 As shown, the flow guide 12 is set at an angle to the height direction of the inner plate body 1. One end of the flow guide 12 connected to the main body 11 is located above the other end along the height direction of the inner plate body 1, and the end of the flow guide 12 connected to the main body 11 is closer to the main body 11 than the other end. This allows the liquid in the chamber 4 to flow quickly and efficiently to the first leakage hole 121 under its own gravity.

[0064] In other embodiments, the flow guide 12 is set at an angle to the height direction of the inner plate body 1, and one end of the flow guide 12 connected to the main body 11 is located below the other end along the height direction of the inner plate body 1, and the end of the flow guide 12 connected to the main body 11 is closer to the main body 11 than the other end.

[0065] In other embodiments, the flow guide 12 can be replaced with a sub-connecting part, which is connected to the main body 11 and located at the bottom of the main body 11 along the height direction of the inner plate body 1. The sub-connecting part is parallel or perpendicular to the height direction of the inner plate body 1, and the first leakage hole 121 is provided in the sub-connecting part. It is understood that the sub-connecting part does not have a flow guiding function in this case.

[0066] Specifically, such as Figure 1-5 As shown, the inner panel body 1 also includes a door outer panel connecting portion 13 connected to the guide portion 12. The door outer panel connecting portion 13 is located at the bottom of the guide portion 12 along the height direction of the inner panel body 1. The door outer panel connecting portion 13 is used for connecting the door outer panel 3. This arrangement forms a chamber 4 between the inner panel body 1 and the door outer panel 3; secondly, it ensures that the first leakage hole 121 is basically located at the bottom of the chamber 4, which further improves the effect of draining the residual liquid in the chamber 4.

[0067] Specifically, in this embodiment, as Figure 4 and Figure 5 As shown, the exemplary arrangement of the door outer panel connecting part 13 and the guide part 12 is at an obtuse angle, and the door outer panel connecting part 13 is parallel to the height direction of the inner panel body 1.

[0068] Specifically, in this embodiment, the outer door panel 3 and the connecting portion 13 are welded together. This improves the sealing performance and connection reliability of the formed chamber 4. In other embodiments, the outer door panel 3 and the connecting portion 13 can also be connected as a whole using bolts and nuts.

[0069] In this embodiment, the main body 11, the guide portion 12, and the door outer panel connecting portion 13 of the inner panel body 1 are formed by sheet metal stamping. Using sheet metal stamping to form the inner panel body 1 results in high production efficiency and low production cost; furthermore, the quality of the produced inner panel body 1 is stable.

[0070] Specifically, in this embodiment, the inner plate body 1 is integrally stamped from an aluminum plate. Aluminum plates have advantages such as being lightweight, having high tensile strength, good plasticity, and being corrosion resistant.

[0071] In other embodiments, the main body 11, the guide section 12 and the door outer panel connecting section 13 can be formed separately from sheet metal, and then the main body 11, the guide section 12 and the door outer panel connecting section 13 can be spliced ​​together to form the inner panel body 1.

[0072] Stamping refers to the process of applying external force to metal sheets (such as steel plates, steel strips, aluminum plates, etc.) using a press and molds, and obtaining metal parts with the required shape, size and performance requirements through plastic deformation or separation processes.

[0073] Optionally, in this embodiment, as Figure 1 As shown, the first sub-hole 1211 is cylindrical. The cylindrical shape of the first sub-hole 1211 makes it easier to process the first sub-hole 1211 and the first sealing member 2 compared to a cuboid hole, and can further improve the aesthetics of the formed inner door panel.

[0074] In this embodiment, as Figure 2 and Figure 4 As shown, the exemplary configuration of the first sealing member 2 includes a first sealing portion 21 and a second sealing portion 22 and a third sealing portion 23 connected to the axial ends of the first sealing portion 21. The first sealing portion 21 is inserted into the first sub-hole 1211, causing the second sealing portion 22 and the third sealing portion 23 to respectively seal the guide portion 12 on both sides along the thickness direction. The second sealing portion 22 is located away from the outer door panel 3 relative to the first sealing portion 21. Further, along the through-path of the first sub-hole 1211, the orthographic projections of the end faces of the second sealing portion 22 and the third sealing portion 23 near the first sealing portion 21 along the through-path of the first sub-hole 1211 both cover the first sub-hole 1211. This effectively seals the first sub-hole 1211.

[0075] It is understandable that the specific structure of the first sealing component 2 is not limited, as long as it can effectively seal the first sub-hole 1211.

[0076] In other implementations, the first sub-hole 1211 may also be provided in a cuboid shape, etc.

[0077] Specifically, in this embodiment, the flow cross-section of the first sub-hole 1211 is circular, and the radius of the circle ranges from 5mm to 8mm. That is, the radius of the circle can be 5mm, 6mm, 7mm, 7.5mm, or 8mm, etc. Among them, 5mm is the minimum radius of the first sub-hole 1211 determined by comprehensively considering the leakage performance and process feasibility of the first leakage hole 121, and 8mm is the maximum radius of the first sub-hole 1211 determined by comprehensively considering the leakage performance and aesthetics of the first leakage hole 121. Further, in this embodiment, to combine leakage performance, process feasibility, and aesthetics, the radius of the circle is preferably 7mm.

[0078] Specifically, for cases where the flow cross-section of the first sub-hole 1211 is rectangular or other shapes, the corresponding range of the flow cross-sectional area of ​​the first sub-hole 1211 is set to 78.5 mm. 2 ~200.96mm2 Among them, 78.5mm 2 =π×5 2 mm 2 200.96mm 2 =π×8 2 mm 2 .

[0079] Optionally, in this embodiment, as Figure 1 and Figure 2 As shown, the second sub-hole 1212 is rectangular. Compared to making the second sub-hole 1212 cylindrical, along the height direction of the inner plate body 1, the liquid accumulated near the bottom of the second sub-hole 1212 in the chamber 4 can flow out of the second sub-hole 1212 more quickly and smoothly.

[0080] It is understood that the shape of the first leakage hole 121 formed in this embodiment is approximately the same as the shape of the keyhole.

[0081] In other embodiments, the second sub-hole 1212 may also be cylindrical or the like.

[0082] In other embodiments, the first leakage hole 121 formed by the first sub-hole 1211 and the second sub-hole 1212 may also be cylindrical or cuboid in shape. In other embodiments, the first sub-hole 1211 and the second sub-hole 1212 of the first leakage hole 121 may be connected by an intermediate hole. Specifically, the intermediate hole extends along the height direction of the inner plate body 1 through the inner peripheral walls of the first sub-hole 1211 and the second sub-hole 1212, thereby connecting the first sub-hole 1211 and the second sub-hole 1212 to form the first leakage hole 121. The shape of the intermediate hole, such as a cuboid, is not limited, as long as it can connect the first sub-hole 1211 and the second sub-hole 1212.

[0083] Optionally, such as Figure 3 As shown, there are at least two first leakage holes 121, and these at least two first leakage holes 121 are spaced apart along the width direction of the inner plate body 1. This allows the liquid in the chamber 4 to flow out more quickly and efficiently.

[0084] In this embodiment, as Figure 3 As shown, the exemplary configuration specifies two first leakage holes 121. It is understood that the number of first leakage holes 121 can be adjusted according to actual needs.

[0085] Optionally, such as Figure 1 , Figure 2 and Figure 4As shown, the first sealing member 2 also partially seals the second sub-hole 1212. This arrangement ensures that, while maintaining the leakage performance of the second sub-hole 1212, it can further alleviate the problem of increased cabin noise caused by not sealing the leakage hole in the prior art during normal vehicle operation; secondly, it can further improve the aesthetics of the inner panel body 1.

[0086] Further, optionally, in this embodiment, such as Figure 2 and Figure 4 As shown, along the height direction of the inner panel body 1, the portion of the second sub-hole 1212 near the first sub-hole 1211 is blocked by the first sealing member 2, while the remaining portion remains connected to both sides of the inner panel body 1 along its thickness direction. That is, along the height direction of the inner panel body 1, the second sealing portion 22 of the first sealing member 2 blocks the portion of the second sub-hole 1212 near the first sub-hole 1211. This arrangement further enhances the aesthetics of the door inner panel; secondly, it further reduces the processing difficulty of the first sealing member 2.

[0087] In other embodiments, one end of the second sub-hole 1212 along the width direction of the inner plate body 1 may be blocked by the first sealing member 2.

[0088] Further, optionally, in this embodiment, such as Figure 1 and Figure 2 As shown, the area of ​​the first sealing member 2 that blocks the second sub-hole 1212 is the first area, and the unblocked flow cross-sectional area of ​​the second sub-hole 1212 is the second area, where the first area > the second area. This arrangement ensures the leakage performance of the second sub-hole 1212 while further mitigating the problem of increased cabin noise caused by not sealing the leakage hole in the prior art during normal vehicle operation.

[0089] In other embodiments, the first area may be equal to the second area. Alternatively, the first area may be less than the second area.

[0090] Optionally, such as Figure 3 As shown, the guide section 12 is also provided with a second leakage hole 122; the inner panel of the door also includes a second sealing member, which can selectively seal the second leakage hole 122.

[0091] During the painting process of the door assembly, the second sealing component is kept unblocked from the second leakage hole 122, which further improves the efficiency of liquid outflow from the chamber 4. During normal vehicle use, the second sealing component is kept blocking the second leakage hole 122 to avoid increased noise in the driver's cabin caused by the second leakage hole 122 not being blocked.

[0092] Optionally, in this embodiment, as Figure 3As shown, the second drain hole 122 is cylindrical. The cylindrical shape of the second drain hole 122 facilitates the machining of both the second drain hole and the second sealing component compared to a cuboid hole, and further enhances the aesthetics of the door inner panel.

[0093] In this embodiment, the structure of the second sealing element is similar to that of the first sealing element 2, so it will not be described in detail here. It is understood that the specific structure of the second sealing element is not limited, as long as it can effectively seal the second leakage hole 122.

[0094] In other implementations, the second leakage hole 122 may also be provided in a cuboid shape, etc.

[0095] Optionally, the number of second drain holes 122 is at least two, and the at least two second drain holes 122 are spaced apart along the width direction of the inner panel body 1. During the painting process of the door assembly, the liquid in the chamber 4 can be drained more quickly and efficiently.

[0096] In this embodiment, as Figure 3 As shown, the exemplary configuration includes one second leakage hole 122. This second leakage hole 122 is located between two first leakage holes 121.

[0097] Among them, such as Figure 5 As shown, the inner door panel also includes a door lock reinforcing plate 5, which is fixedly connected to the inner panel body 1. The door lock reinforcing plate 5 is used to fix the door lock, so that the formed door assembly can be locked or unlocked with the vehicle body. The specific structures of the door lock reinforcing plate 5 and the door lock are both prior art, and therefore will not be described in detail here.

[0098] Specifically, such as Figure 5 As shown, the door lock reinforcement plate 5 is located inside the chamber 4. Along the height direction of the inner panel body 1, the first leakage hole 121 is located below the door lock reinforcement plate 5. Figure 5 As shown, the airflow guide 12 and the door outer panel connecting part 13 are both located below the door lock reinforcement plate 5.

[0099] This utility model also provides a door assembly, such as Figure 4 and Figure 5 As shown, the door includes an outer panel 3 and an inner panel, and a cavity 4 is formed between the outer panel 3 and the inner panel body 1. The cavity 4 is connected to the first leakage hole 121.

[0100] By adopting the aforementioned door inner panel, the problem of increased cabin noise caused by not sealing the leakage hole in the prior art can be effectively alleviated, while the problem of residual liquid leakage in the cavity caused by sealing the leakage hole in the prior art can also be effectively alleviated.

[0101] Specifically, in this embodiment, as Figure 4 and Figure 5 As shown, the exemplary configuration involves folding the bottom of the outer door panel 3 along its height towards the side closest to the inner panel body 1 to form a slot. The connecting portion 13 of the outer door panel is partially inserted into the slot and welded to the inner wall of the slot. This further enhances the connection reliability and sealing reliability between the inner panel body 1 and the outer door panel 3.

[0102] Specifically, in this embodiment, the door assembly is exemplified as the tailgate assembly. It can be understood that the inner panel body 1 is the tailgate inner panel, the door outer panel 3 is the tailgate outer panel, and the door lock is the tailgate lock.
