Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a door structure, body, and vehicle. Background Technology

[0002] The bottom of the car door is usually equipped with a drain hole that connects to the door cavity. Water that enters the door cavity from the door handle and other parts will be discharged through the drain hole at the bottom of the door.

[0003] When a vehicle is traveling at high speed, airflow enters the door cavity through the drain hole. The airflow in the door cavity then enters the door and window frame cavity. Because there are narrow gaps in the door and window frames that form the door and window frame cavity, the airflow in the door and window frame cavity may enter the cabin through these narrow gaps, producing a whistling sound and thus affecting the overall comfort of the vehicle. Utility Model Content

[0004] The purpose of this utility model is to propose a door structure, body and vehicle that can block the airflow between the door panel cavity and the door and window frame cavity, thereby improving the NVH performance of the whole vehicle.

[0005] To achieve this objective, firstly, the present invention provides:

[0006] The door structure includes:

[0007] The door and window frame portion has a door and window frame cavity;

[0008] The door panel portion has a door panel cavity, and the door / window frame portion is connected to the door panel portion;

[0009] A partition is provided at the junction of the door / window frame cavity and the door panel cavity, and the partition separates the door / window frame cavity and the door panel cavity.

[0010] As one feasible technical solution for the aforementioned door structure, the door panel includes an outer door panel, and the partition is located above the outer door panel.

[0011] As one feasible technical solution for the aforementioned door structure, the partition portion is provided at both the front and rear ends of the door and window frame cavity.

[0012] As one feasible technical solution for the aforementioned door structure, the partition includes:

[0013] An expansion seal is disposed within the cavity of the door / window frame.

[0014] As one feasible technical solution for the aforementioned door structure, the partition portion further includes:

[0015] The body is disposed on the door / window frame, and the expansion seal is disposed on the body.

[0016] As one feasible technical solution for the above-mentioned door structure, the main body is provided with a process hole that extends through the door and window frame cavity, and at least one end of the process hole is blocked by the expansion seal.

[0017] And / or, a gap is formed between the outer peripheral wall of the body and the inner wall of the door / window frame cavity, and at least one end of the gap is sealed by the expansion seal.

[0018] As one feasible technical solution for the aforementioned door structure, the inner wall of the door / window frame cavity is provided with a mounting part, and the main body is mounted on the mounting part.

[0019] As one feasible technical solution for the above-mentioned door structure, the inner wall of the door / window frame cavity is provided with a reinforcing member, which includes the mounting part.

[0020] Secondly, the vehicle body provided by this utility model includes a door structure as described in any of the above-described feasible embodiments.

[0021] Thirdly, the vehicle provided by this utility model includes a body as described in any of the above-described embodiments.

[0022] This utility model has at least the following beneficial effects:

[0023] The door structure provided by this utility model allows external airflow to enter the door panel cavity through the drainage hole at the bottom of the door panel when the vehicle is in motion. However, because the partition separates the door and window frame cavity from the door panel cavity, the airflow in the door panel cavity will not enter the door and window frame cavity.

[0024] The vehicle body provided by this utility model includes the aforementioned door structure. By using a partition, the door and window frame cavity and the door panel cavity are separated, so that the external airflow enters the door panel cavity through the drainage hole and will not enter the door and window frame cavity through the door panel cavity. This prevents the airflow in the door panel cavity from entering the cabin through the door and window frame cavity and the narrow gaps on the door and window frame, thus avoiding the whistling sound.

[0025] The vehicle provided by this utility model, including the aforementioned body, prevents airflow in the door panel cavity from entering the cabin through the door and window frame cavity and the narrow gaps on the door and window frame, thus avoiding whistling noise and improving the overall NVH performance of the vehicle.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] For ease of description and understanding, in the embodiments of this utility model, the direction from the front to the rear of the vehicle along the length of the vehicle is the direction from front to back; regarding the directional terms "inner" and "outer", the inner side of a structure refers to the side of the structure that is close to the central axis of the vehicle extending in the front-rear direction, and the outer side of a structure refers to the side of the structure that is opposite to the central axis of the vehicle extending in the front-rear direction.

[0042] like Figure 1 and Figure 2 As shown, the door structure provided in this embodiment includes a door and window frame portion and a door panel portion, wherein the door and window frame portion has a door and window frame cavity 10, the door panel portion has a door panel cavity 20, and the door and window frame portion and the door panel portion are connected.

[0043] Specifically, the door structure includes an outer part and an inner part. The inner part is a one-piece molded structure, including an inner door window frame 12 and an inner door panel 22. The outer part includes an outer door window frame 11 and an outer door panel 21. A door panel cavity 20 is formed between the outer door panel 21 and the inner door panel 22. A door window frame cavity 10 is formed between the inner door window frame 12 and the outer door window frame 11. The lower end of the outer door window frame 11 extends into the door panel cavity 20.

[0044] The bottom of the door panel has a drain hole 23 that connects the door panel cavity 20 to the outside atmosphere. A door handle is installed on the outer side of the door outer panel 21. A drainage channel is formed inside the door panel cavity 20, and the lower end of the drainage channel is connected to the drain hole 23. Water at the location of the door handle can enter the drainage channel and be discharged through the drain hole 23. It should be noted that the formation of the drainage channel and the installation of the door handle are existing technologies in the art and will not be described in detail here.

[0045] In some embodiments, multiple drain holes 23 are provided, and the multiple drain holes 23 are spaced apart in the front-to-back direction. For example, three drain holes 23 are provided. In other embodiments, two, four, or more drain holes 23 may also be provided.

[0046] In some embodiments, the outer door and window frame 11 and the inner door and window frame 12 are welded and fixed to form the aforementioned door and window frame cavity 10. Exemplarily, the outer door and window frame 11 is a sheet metal structural component, the inner door and window frame 12 and the inner door panel 22 are integrally formed sheet metal structural components, and the outer door panel 21 is a sheet metal structural component.

[0047] The circumferential edge of the outer door panel 21 is folded inward to form a edging structure, and the circumferential edge of the inner door panel 22 is covered within the space enclosed by the edging structure and the outer door panel 21, thereby forming the aforementioned door panel cavity 20 between the outer door panel 21 and the inner door panel 22. For example, the aforementioned drainage hole 23 is provided on the edging structure of the outer door panel 21.

[0048] During vehicle operation, external airflow enters the door panel cavity 20 through the drain hole 23, and then enters the door and window frame cavity 10 from the door panel cavity 20. The airflow in the door and window frame cavity 10 enters the cabin through the narrow gaps on the door and window frame, producing a whistling sound, which affects the user's driving experience.

[0049] It should be noted that the narrow gaps on the inner door and window frame 12 refer to the various narrow gaps that may exist after the various processing holes on the inner door and window frame 12 are sealed with sealing strips, due to various reasons such as processing errors, assembly errors, the position of the processing holes and special shapes. When airflow is in circulation, the airflow in the door and window frame cavity 10 will enter the vehicle cabin through these narrow gaps.

[0050] In view of this, such as Figure 3 and Figure 4 As shown, the door structure of the embodiment of this utility model also includes a partition 3, which is located at the junction of the door and window frame cavity 10 and the door panel cavity 20, and the partition 3 separates the door and window frame cavity 10 and the door panel cavity 20.

[0051] When the vehicle is in motion, the outside airflow enters the door panel cavity 20 through the drainage hole 23 at the bottom of the door panel. Since the partition part 3 separates the door and window frame cavity 10 and the door panel cavity 20, the airflow in the door panel cavity 20 will not enter the door and window frame cavity 10. This prevents the airflow in the door panel cavity 20 from entering the cabin through the narrow gaps on the door and window frame cavity 10 and the inner door and window frame 12, thus avoiding the whistling sound. This improves the user's comfort experience and enhances the NVH performance of the entire vehicle.

[0052] It should be noted that NVH stands for Noise, Vibration, and Harshness.

[0053] It should be noted that the reference Figure 3 As shown, with the horizontal plane containing the upper end face of the outer door panel 21 as the boundary line, the door and window frame cavity 10 refers to the inner cavity of the door and window frame portion located above the boundary line, and the door panel cavity 20 refers to the inner cavity of the door panel portion located below the boundary line. In this embodiment of the utility model, the partition part 3 is provided at the junction of the door and window frame cavity 10 and the door panel cavity 20, which can effectively prevent the airflow in the door panel cavity 20 from entering the door and window frame cavity 10. Figure 3 and Figure 4 The position of the partition 3 is only shown in an enlarged illustration; in actual application, the distance between the partition 3 and the outer door panel 21 is relatively close.

[0054] In some embodiments, the outer door / window frame 11 has a ring-shaped structure, including an upper frame, a front frame, a lower frame, and a rear frame connected end to end. The upper frame is located above the lower frame, the front frame is located in front of the rear frame, and the lower frame is located between the inner door panel 22 and the outer door panel 21. The gap between the inner door panel 22 and the lower frame makes it inconvenient to arrange a partition structure. Therefore, the partition part 3 is located above the outer door panel 21.

[0055] Specifically, the partition 3 is located above the lower frame. There are two partitions 3, referred to as the front partition and the rear partition. The front partition is located between the front frame and the outer door and window frame 11, and the rear partition is located between the rear frame and the outer door and window frame 11. In other words, the front and rear ends of the door and window frame cavity 10 are equipped with partitions 3.

[0056] In some embodiments, such as Figures 3 to 6As shown, the partition 3 includes an expansion seal 31, which fills the cavity 10 of the door and window frame. The expansion seal 31 expands and deforms to separate the cavity 10 of the door and window frame and the cavity 20 of the door panel located above the expansion seal 31.

[0057] In some embodiments, such as Figures 3 to 6 As shown, the partition 3 also includes a body 32, which is disposed on the door and window frame, and the expansion seal 31 is disposed on the body 32. After the expansion seal 31 expands and deforms, it is easy to fall off or become misaligned. By fixing the expansion seal 31 to the door and window frame through the body 32, stable support can be provided before, during and after the expansion seal 31 expands.

[0058] In some embodiments, such as Figures 3 to 6 As shown, the inner wall of the door and window frame cavity 10 is provided with a mounting part, and the main body 32 is installed in the mounting part. With this configuration, the main body 32 can be installed in the door and window frame without drilling holes in the outer door and window frame 11 and the inner door and window frame 12.

[0059] In some embodiments, the aforementioned expansion sealant 31 is expanding foam. Exemplarily, the expanding foam is a copolymer of ethylene and vinyl acetate. The expanding foam can both bond to the inner wall of the door / window frame cavity 10 and, after baking and expansion, seal the door / window frame cavity 10. After expansion and curing, the expanding foam has multiple effects such as adhesion, sealing, and sound absorption, and also has the advantages of energy saving and environmental protection.

[0060] In other embodiments, the material of the expansion seal 31 includes natural rubber, a foaming agent, and polyisobutylene. Alternatively, the material of the expansion seal 31 can be EPDM rubber, a foaming agent, and polyisobutylene. Both of these materials are existing technologies in the art, and the content of each component is no longer limited. The expansion strip can also be adhered to the inner wall of the door / window frame cavity 10, leaving a gap. After being baked and expanded, the expansion strip fills the door / window frame cavity 10, thereby achieving the purpose of sealing and partitioning.

[0061] It should be noted that the shape of the expanded polystyrene after foaming depends on the cross-sectional shape of the cavity 10 of the door and window frame where the expanded polystyrene is located, and is not specifically limited here.

[0062] In some embodiments, the inner and outer walls of the outer door and window frame 11, as well as the inner and outer walls of the inner door and window frame 12, are all covered with an electrophoretic paint layer. The electrophoretic paint layer can completely cover all the hidden areas of the inner and outer walls of the outer door and window frame 11, as well as the inner and outer walls of the inner door and window frame 12. The thickness of the electrophoretic paint layer is relatively uniform, it is not easy to peel off, and it has excellent corrosion resistance.

[0063] In some embodiments, such as Figures 3 to 6As shown, the body 32 has a process hole extending along the extension direction of the door / window frame cavity 10, and the process hole is filled with an expansion sealant 31. Before the expansion sealant 31 is foamed, the door / window frame cavity 10 and the door panel cavity 20 are connected through the process hole. After the expansion sealant 31 is foamed, the process hole is sealed by the expansion sealant 31. Exemplarily, the body 32 is made of polyamide 66 or nylon 66, both of which are formed by the condensation polymerization of adipic acid and hexamethylenediamine.

[0064] Specifically, the expansion seal 31 is disposed on the upper surface of the body 32 before expansion, and the expansion seal 31 surrounds the outer periphery of the process hole, so that a guide hole 311 is formed on the expansion seal 31 before foaming. The process hole includes an electrophoresis liquid hole. When electrophoresis is performed on the door structure, the electrophoresis liquid in the door panel cavity 20 enters the door and window frame cavity 10 through the electrophoresis liquid hole, so that an electrophoresis layer is formed on the inner wall of the door and window frame cavity 10. After electrophoresis is completed, the electrophoresis liquid in the door and window frame cavity 10 returns to the lower door panel cavity 20 through the electrophoresis liquid hole.

[0065] After the electrophoretic solution is discharged, the expansion seal 31 is heated and expanded. During the expansion process, the guide hole 311 can guide the expansion deformation of the expansion seal 31, making the expansion deformation of the expansion seal 31 more uniform. The guide hole 311 is filled by the expanded expansion seal 31, so that the end of the process hole near the expansion seal 31 is blocked by the expanded expansion seal 31. This achieves the purpose of using the expansion seal 31 to separate the door panel cavity 20 and the door and window frame cavity 10 above the inner door panel 22, resulting in a good sealing effect.

[0066] For example, the body 32 and the expansion seal 31 are formed by secondary injection molding, which is simple in molding process. The connection between the body 32 and the expansion seal 31 is relatively firm, which can effectively prevent the expansion seal 31 from shifting relative to the body 32 during the process of thermal expansion.

[0067] In some embodiments, such as Figure 5 and Figure 6 As shown, multiple process holes are provided, spaced apart on the expansion seal 31 before foaming. This arrangement facilitates the flow of more electrophoretic liquid through the electrophoretic liquid holes between the door panel cavity 20 and the door / window frame cavity 10, thereby improving electrophoresis efficiency.

[0068] For example, three process holes are provided. It should be noted that the number of process holes is not limited to three; it can also be two, four, five, or more.

[0069] In some embodiments, such as Figure 5 and Figure 6As shown, a gap is formed between the outer peripheral wall of the body 32 and the inner wall of the door and window frame cavity 10, and at least one end of the gap is sealed by the expansion seal 31.

[0070] During the electrophoresis process before the expansion seal 31 expands, this gap can also be used to flow the electrophoresis liquid, improving the electrophoresis efficiency. When the expansion seal 31 is set on one side of the body 32, the side of this gap near the expansion seal 31 is blocked by the expanded expansion seal 31, achieving the purpose of using the expansion seal 31 to separate the door panel cavity 20 and the door and window frame cavity 10, resulting in a good sealing effect.

[0071] Furthermore, connecting the outer door and window frame 11 and the inner door and window frame 12 with a gap prevents the body 32 and the expansion seal 31 from interfering with the installation of the outer door and window frame 11 and the inner door and window frame 12. Since the outer door and window frame 11 and the inner door and window frame 12 are connected by welding, the gap is reserved due to the high temperature of the welding laser, which can also prevent damage to the expansion seal 31 during welding, ensuring that the expansion seal 31 is not damaged and reducing the overall vehicle defect rate; it can also ensure that the laser welding torch does not explode. Under normal circumstances, the width of the gap 31 between the expansion seal 31 and the inner wall of the door and window frame cavity 10 is L, 3mm≤L≤10mm. L can be any value greater than or equal to 3mm and less than or equal to 10mm, such as any value among 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm and 10mm. When L is less than 3mm, the expansion seal 31 is easily damaged when welding the outer door and window frame 11 and the inner door and window frame 12; when L is greater than 10mm, the expansion seal 31 may not be able to completely seal the gap after it expands and deforms, thus reducing the sealing effect.

[0072] In some other embodiments, in order to ensure that the expansion seal 31 can seal the gap after expansion, the expansion seal 31 can also be fixed on the outer peripheral wall of the body 32 so that the expansion seal 31 can seal the gap after expansion.

[0073] In some embodiments, such as Figure 3 and Figure 4 As shown, the inner wall of the door and window frame cavity 10 is provided with a reinforcing member 13, which includes the aforementioned mounting part. There is no need to add an additional structure for mounting the main body 32 inside the door and window frame cavity 10; instead, the main body 32 is mounted using the reinforcing member 13 located on the inner wall of the door and window frame cavity 10. This improves the integration of the door structure, reduces the number of parts, and lowers processing costs.

[0074] Specifically, the reinforcing member 13 is welded and fixed to the inner wall of the outer door and window frame 11. The fixing method of the reinforcing member 13 is simple and low in cost. In other embodiments, when the inner wall of the inner door and window frame 12 is provided with a reinforcing structure, the above-mentioned reinforcing structure can also be used to install the main body 32; the reinforcing member 13 and the outer door and window frame 11 can also be integrally formed, such as by integrally casting the reinforcing member 13 and the outer door and window frame 11, reducing subsequent assembly processes, reducing production costs, and ensuring the connection stability between the reinforcing member 13 and the outer door and window frame 11; the reinforcing member 13 can also be glued and fixed to the inner wall of the outer door and window frame 11.

[0075] In some embodiments, such as Figure 3 and Figure 4 As shown, the main body 32 is disposed on the top of the reinforcing member 13, and the main body 32 is supported by the reinforcing member 13.

[0076] For example, the body 32 is snapped into the mounting part. Specifically, the upper end of the reinforcing member 13 is bent inward to form a bent part, and a snap hole is provided on the bent part. The snap hole passes through the bent part vertically. The body 32 includes a fixing part for fixing the expansion seal 31, and a buckle 321 connected to one side of the fixing part. One end of the buckle 321 abuts against the upper surface of the bent part, and the other end of the buckle 321 deforms as it passes through the snap hole, and returns to its original shape after passing through the snap hole to abut against the lower surface of the bent part, thereby snapping the body 32 into the reinforcing member 13. The installation of the body 32 is convenient and improves the installation efficiency of the door structure.

[0077] In other embodiments, the body 32 and the mounting part can also be snapped together. Specifically, a threaded hole is provided on the body 32, and a through hole is provided on the bent part. After fasteners such as screws are passed through the through hole, they are threaded into the threaded hole, and the head of the screw abuts against the side of the bent part opposite to the body 32.

[0078] In some embodiments, such as Figure 3 and Figure 4 As shown, the reinforcing member 13 has a multiple repeated bending structure, which helps to improve the structural strength of the reinforcing member 13. Exemplarily, the reinforcing member 13 is a sheet metal structural member.

[0079] In some embodiments, the reinforcing member 13 is welded and fixed to the inner wall of the outer door and window frame 11 at multiple locations. This arrangement improves the connection stability between the reinforcing member 13 and the outer door and window frame 11, thereby achieving the purpose of improving the structural strength of the outer door and window frame 11 by utilizing the reinforcing member 13.

[0080] An embodiment of this utility model also provides a vehicle body, which includes a vehicle body and a door structure provided in any of the above embodiments. The door structure is rotatably mounted on the vehicle body. The vehicle body includes the aforementioned door structure, which separates the door and window frame cavity 10 and the door panel cavity 20 through a partition structure. Airflow entering the door panel cavity 20 through the drainage hole 23 will not enter the door and window frame cavity 10 above the partition 3, thus preventing airflow in the door panel cavity 20 from entering the cabin through the door and window frame cavity 10 and the narrow gaps on the door and window frame, which would cause whistling noise.

[0081] It should be noted that the above-mentioned door structure can be the front door or the rear door, or the partition structure can be installed on both the front door and the rear door.

[0082] An embodiment of this utility model also provides a vehicle including the aforementioned body. This vehicle includes a body using the aforementioned door structure, preventing airflow within the door panel cavity 20 from entering the cabin through the door / window frame cavity 10 and narrow gaps in the door / window frame, thus avoiding whistling noise and improving the overall NVH performance of the vehicle.

[0083] Furthermore, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments. Many other equivalent embodiments may be included without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
