Abstract
Description
Technical Field
[0001] This application relates to the field of automotive body component technology, specifically to a roll-stamped combined zero-step difference door structure and an automobile. Background Technology
[0002] With the development of automotive technology and the increasing demands of users for the appearance and performance of cars, higher requirements have been placed on the smoothness of the car body appearance. The step difference between the traditional door glass and the window frame not only makes the appearance uneven, but also causes wind noise during vehicle operation. The zero-step difference door structure helps to reduce wind noise during vehicle operation, while making the car appearance cleaner.
[0003] One proposed zero-step door structure includes a reinforcing plate, an outer panel, a glass assembly, a guide, a sliding groove, and a seal. The guide drives the glass assembly to move up and down along the extension direction of the sliding groove, achieving coplanarity between the outer surface of the glass assembly and the outer surface of the outer panel. However, in this structure, the mounting plate is stamped, and the sliding groove and mounting plate are welded together. The welding process has a significant impact on the precision of the parts, and since this area is the glass lifting area, the precision issue will affect the smoothness of the glass lifting. Furthermore, the sliding friction between the seal and the guide can easily wear down the seal, causing noise and other problems. Another proposed zero-step door glass structure includes an inner panel, an outer panel, a glass assembly, and a window frame groove. The window frame groove enables the movement of the glass assembly. However, in this structure, the window frame groove is located between the inner and outer panels, requiring multi-layered connections, which affects the overall precision. The structure of the limiting components and the auxiliary groove is complex, making the assembly process prone to deviations.
[0004] Therefore, due to the limitations of its own structure, the existing car door structure usually requires multi-level welding and assembly, which often requires a lot of manpower and mechanical equipment, increasing production costs; the assembly process is too long, the production efficiency is low, resulting in a long production cycle; multiple welding and assembly processes are prone to deviations and errors, making it difficult to guarantee the quality of the car door.

[0017] In a preferred embodiment, the window frame assembly further includes an inner window frame panel, the inner window frame panel and the inner window frame panel together forming a closed cavity, wherein the inner window frame panel is configured to be formed by stamping.
[0018] In a preferred embodiment, the door structure further includes a sealing assembly, the sealing assembly comprising:
[0019] The door sealing strip and the door frame sealing strip are respectively connected to the side wall of the inner panel of the window frame to seal the gap between the inner panel of the window frame and the side components of the vehicle.
[0020] A waterproof sealing strip is connected to the outer panel of the window frame to seal the space between the outer panel of the window frame and the door glass;

[0023] Compared with the prior art, this application has the following advantages:
[0024] This invention proposes a roll-pressed, zero-step-difference car door structure, comprising: a window frame assembly and a glass assembly; the window frame assembly includes an outer window frame panel and a window frame decorative panel, and the glass assembly includes a door glass and a connecting member; the outer window frame panel is connected to the door glass and the window frame decorative panel respectively; wherein, the outer window frame panel includes a guide member, which is configured to be roll-pressed from the outer window frame panel, and the guide member cooperates with the connecting member so that when the door glass is assembled onto the outer window frame panel, the outer surface of the door glass is flush with the outer surface of the window frame decorative panel. By adopting the technical solution of this application, the outer panel of the window frame is formed by roll forming, that is, the guide component is formed by roll forming. This allows the guide component to adapt to complex curved shapes during the forming process, thereby enabling the design of matching structural features for the connecting components. Since the structures of the connecting components and the guide components are absolutely matched, when the door glass and the window frame trim panel are installed on the outer panel of the window frame, they correspond to this structural feature, thereby achieving a zero surface difference between the outer surface of the door glass and the outer surface of the window frame trim panel. Furthermore, this structural feature allows for one-time assembly of the outer panel of the window frame and the door glass, reducing multi-level welding and assembly processes. This reduces manpower and material resources in the manufacturing and assembly process, improves production efficiency, reduces production costs, and achieves good precision control.

[0037] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.
[0038] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.
[0039] It can be understood that the step difference between the door glass 3 and the window frame can be defined as the deviation of their relative positions in three directions: horizontal (X-axis), vertical (Y-axis), and front-to-back (Z-axis). Specifically, the step difference in the horizontal direction reflects whether their left and right edges are aligned; the step difference in the vertical direction reflects whether their top and bottom edges are aligned; and the step difference in the front-to-back direction reflects whether the door glass 3 moves forward or backward within the window frame. The smaller the step difference, the higher the matching degree between the door glass 3 and the window frame, which has a significant impact on the door's sealing, waterproofing, and noise control.
[0040] Please refer to Figures 1-4 As shown, Figure 1 The following diagram illustrates a door structure according to some embodiments of the present disclosure; Figure 2 An exemplary door structure having a door sealing strip 8 according to some embodiments of the present disclosure is shown; Figure 3 Exemplary window frame assemblies according to some embodiments of the present disclosure are shown; Figure 4 Exemplary cooperating guide members and connecting members according to some embodiments of the present disclosure are shown.
[0041] This invention provides a roll-stamped, zero-step-difference car door structure, comprising: a window frame assembly and a glass assembly; the window frame assembly includes an outer window frame panel 1 and a decorative window frame panel 5, and the glass assembly includes a door glass 3 and connecting components; the outer window frame panel 1 is connected to both the door glass 3 and the decorative window frame panel 5; wherein...
[0042] The outer panel 1 of the window frame includes a guide member, which is configured to be roll-formed by the outer panel 1 of the window frame. The guide member cooperates with the connecting member so that when the door glass 3 is assembled onto the outer panel 1 of the window frame, the outer surface of the door glass 3 is flush with the outer surface of the window frame decorative panel 5.
[0043] Specifically, the window frame assembly, glass assembly, and sealing assembly constitute the three main parts of the vehicle door structure. The window frame assembly can be understood as the frame that supports and fixes the glass assembly, serving to support and protect the door glass 3. It also works with the sealing assembly to provide a seal, preventing external dust and moisture from entering the door interior. The door glass 3 in the glass assembly provides a clear view inside the vehicle and also protects occupants, such as preventing impacts from external objects and rainwater from entering the vehicle. In this embodiment, the door glass 3 is connected to the outer panel 1 of the window frame. The outer panel 1 of the window frame is roll-formed with guide members. The door glass 3 can be assembled with the guide members via connecting members. Through the cooperation of the guide members and connecting members, the outer panel 1 of the window frame and the door glass 3 are connected.
[0044] As a specific explanation of this embodiment, roll forming uses a set of rollers or cylinders to deform the material, thereby achieving the forming purpose. It can produce parts with complex contours, such as window frame outer panels 1. Window frame outer panels 1 connect to the door glass 3, provide guidance during assembly, have a limiting function after assembly, and provide mounting surfaces and snap-fit holes 14 for window frame trim. Through roll forming, the window frame outer panel 1 is pressed into a certain shape and size, forming structural features that match the connecting components. These structural features are simple and easy to assemble. Because the structural features of the guiding components perfectly match the structural features of the connecting components, the connection between the window frame outer panel 1 and the door glass 3 can be completed simultaneously in a single process, eliminating the need for complex assembly steps such as welding. This reduces multi-level welding and assembly processes, decreases manpower and material resources in the manufacturing and assembly process, improves production efficiency, reduces costs, and achieves good precision control. The roll forming structure enables the design of structural features on the outer panel 1 of the window frame that match the connecting components. When the door glass 3 and the window frame decorative panel 5 are installed on the outer panel 1 of the window frame, the outer surface of the door glass 3 and the outer surface of the window frame decorative panel 5 can achieve a zero surface difference, thereby improving the aesthetic appearance and reducing wind noise.
[0045] In some embodiments, the door glass 3 is connected to the connecting member by the first adhesive tape 31, which can reduce the number of parts and assembly steps during assembly and effectively avoid problems such as loosening or noise during the lifting and lowering of the door glass 3, thereby improving ride comfort and safety. The first adhesive tape 31 can be a commercially available guide tape or sealing tape, etc.
[0046] It is understood that the outer panel 1 of the window frame is formed by roll forming, and the guide component, as part of the outer panel 1, is also formed by roll forming. At the same time, other components on the outer panel 1 are also formed by roll forming. Therefore, the shape and size of the guide component and other components are highly accurate, which can improve the accuracy and reliability of assembly when combined with the connecting components.
[0047] The window frame assembly also includes an inner window frame panel 2. The outer window frame panel 1 and the inner window frame panel 2 are connected by an edge banding 15 to form a closed cavity. This closed cavity serves as the frame of the door structure, and its large area provides the window frame with good structural rigidity. In some embodiments, the inner window frame panel 2 is formed into a specific shape and size using a stamping process, and is roll-formed to match the outer window frame panel 1 in a specific shape and size. The inner window frame panel 2 and the outer window frame panel 1 can be a single metal or plastic sheet to enhance the structural strength of the window frame assembly, providing additional support and stability, while also cooperating with the sealing assembly to provide a seal. Specifically, the outer window frame panel 1 has a guide member, a joint sealing strip mounting surface 16, and a snap-fit hole 14 for connection to the door glass 3, the joint sealing strip 6, and the window frame decorative panel 5, respectively. The inner window frame panel 2 has a door sealing strip mounting surface 21 and a door frame sealing strip mounting surface 22 for connection to the door sealing strip 8 and the door frame sealing strip 9, respectively.
[0048] In the door structure, the inner window frame panel 2 has a simpler structure than the outer window frame panel 1 and does not support the window glass. Stamping technology, with its advantages of fast forming speed and low cost, can be used to manufacture the inner window frame panel 2, which possesses high strength and precision. Therefore, by using a combination of roll forming and stamping techniques to manufacture the outer window frame panel 1 and stamping technology to manufacture the inner window frame panel 2, both panels can maximize their respective advantages in terms of material deformation characteristics, processing technology, and structural form. This ensures the strength, rigidity, and assembly accuracy of the window frame assembly, further enhancing the zero-step design between the door glass 3 and the window frame trim panel 5.
[0049] This embodiment illustrates a scheme for coordinating the structural features of the guide member with those of the connecting member.
[0050] The guide component includes an X-direction limiting surface 12, an assembly guide surface 11, and a Y-direction limiting surface 13. The assembly guide surface 11 extends obliquely from the end of the X-direction limiting surface in a direction away from the Y-direction limiting surface 13 for a certain period of time, and then bends in the opposite direction to connect with the Y-direction limiting surface 13.
[0051] The connecting member comprises an X-direction connecting surface, an assembly connecting surface, and a Y-direction connecting surface connected sequentially, forming a structure with a groove-shaped opening, the groove-shaped opening accommodating the guide member; wherein...
[0052] The X-direction limiting surface 12 contacts the X-direction connecting surface to limit the offset of the door glass 3 in the X direction;
[0053] The Y-direction limiting surface 13 contacts the Y-direction connecting surface to limit the offset of the door glass 3 in the Y direction.
[0054] Specifically, the connecting member has multiple connecting surfaces forming a groove-shaped opening. The closed end of the groove-shaped opening is connected to the door glass 3 via a first adhesive tape 31. The open end of the groove-shaped opening faces the guide member and accommodates the guide member, so that the peripheral wall of the groove-shaped opening contacts the peripheral wall of the guide member. The connecting member is formed by sequentially connecting an X-direction connecting surface, an assembly connecting surface, and a Y-direction connecting surface. The two ends of the assembly connecting surface are vertically connected downwards to the X-direction connecting surface and the Y-direction connecting surface, forming a "door"-shaped structure. A "door"-shaped guide groove 4 is formed within this structure, and the guide member is located within this guide groove 4. The X-direction limiting surface 12 in the guide member contacts the X-direction connecting surface, which can be face-to-face contact, i.e., the X-direction connecting surface is parallel to the X-direction connecting surface. The Y-direction limiting surface 13 contacts the Y-direction connecting surface, which can also be face-to-face contact, i.e., the Y-direction limiting surface 13 is parallel to the Y-direction connecting surface.
[0055] The guide groove 4 of this invention adopts a "door" shaped structure, which is simple in structure, easy to assemble and easy to control costs.
[0056] In some embodiments, the Y-direction limiting surface 13 is an arc-shaped surface, and the end of the Y-direction connecting surface has a barb 42, which is inserted into the arc-shaped opening. That is, the Y-direction connecting surface and the Y-direction limiting surface 13 are engaged. Since the two sides of the arc-shaped opening are arc-shaped walls, the offset of the Y-direction connecting surface in the Y direction during the raising and lowering of the door glass 3 can be limited. Here, the Y direction can be the depth direction of the vehicle body, that is, the direction from the outer panel 1 of the window frame to the inner panel 2 of the window frame. The two side walls of the arc-shaped opening are spaced a certain distance in the Y direction, and this distance is the opening size of the Y-direction limiting surface 13.
[0057] A plurality of limiting protrusions 41 are provided on the side of the X-direction connecting surface that contacts the X-direction limiting surface 12. The limiting protrusions 41 can be spaced apart along the length of the X-direction connecting surface. In some embodiments, the multiple limiting protrusions 41 are arranged in an array with equal or unequal rows and columns on the X-direction connecting surface; in some embodiments, the multiple limiting protrusions 41 are arranged in a row. The limiting protrusions 41 on the guide groove 4 match the X-direction limiting surface 12 of the window frame outer panel 1, limiting the X-direction offset of the door glass 3 and the connecting components. The X-direction can be the length direction of the vehicle body, i.e., the driving direction of the vehicle.
[0058] The assembly guide surface 11 extends obliquely from the end of the X-direction limiting surface away from the Y-direction limiting surface 13, then bends in the opposite direction to connect with the Y-direction limiting surface 13, resembling a nose-like shape, to guide the assembly during glass assembly. The assembly guide surface 11 can guide the "door"-shaped guide groove 4 towards the Y-direction limiting surface 13, thereby engaging the barb 42 into the arc-shaped opening. Specifically, during the assembly of the door glass 3 and the connecting components to the outer panel 1 of the window frame, the assembly guide surface 11 causes the guide groove 4 to deform. The Y-direction connecting surface that makes up the guide groove 4 will apply a certain force to the Y-direction of the assembly guide surface 11, causing the guide groove 4 to open, or in other words, the angle between the Y-direction connecting surface and the assembly connecting surface becomes larger, causing the Y-direction connecting surface to move along the assembly guide surface 11 to the arc-shaped opening. Since the Y-direction connecting surface is elastic, when it moves to the arc-shaped opening, it is restored by the change of the plastic material of the Y-direction connecting surface itself, causing it to return to the initial shape of the guide groove 4, thereby locking into the arc-shaped opening and forming a self-locking mechanism. After the assembly is in place, the barb 42 locks into the arc-shaped opening, preventing the door glass 3 from falling off in the Y direction.
[0059] In some embodiments, the connecting member may have elastic characteristics; in some embodiments, the Y-direction connecting surface in the connecting member may have elastic characteristics. The connecting member may be made of tough, wear-resistant plastic; in some embodiments, the X-direction connecting surface, the assembly connecting surface, and the Y-direction connecting surface are integrally formed.
[0060] Understandably, when limiting the X-direction offset of the door glass 3 and connecting components, the barb 42 of the Y-direction connecting surface engages with the arc-shaped opening, and the two sidewalls of the arc-shaped opening are connected as one unit through the arc-shaped bottom wall. The barb 42 contacts the arc-shaped bottom wall, which helps to limit the X-direction offset of the door glass 3 and connecting components. Similarly, when limiting the Y-direction offset of the door glass 3 and connecting components, the X-direction connecting surface and the X-direction limiting surface 12 also have a contact area in the Y-direction, thus helping to limit the Y-direction offset of the door glass 3 and connecting components. In this way, the deformation of the guide groove 4 and the guiding effect of the assembly guide surface 11 ensure that the door glass 3 is correctly installed on the outer panel 1 of the window frame and tightly connected to other components.
[0061] like Figure 5 As shown, Figure 5 A schematic diagram of the installation of the window frame decorative panel 5 and the window frame outer panel 1 of the present invention is shown.
[0062] In another embodiment, a plurality of connectors 52 are provided between the outer window frame panel 1 and the decorative window frame panel 5, and the outer window frame panel 1 has a snap-fit hole 14, while the decorative window frame panel 5 has a mounting bracket 51, which snaps into the snap-fit hole 14. In this embodiment, the snap-fit hole 14 of the outer window frame panel 1 is configured to provide mounting positioning for the decorative window frame panel 5, which is snapped onto the outer window frame panel 1 by the mounting bracket 51 on the decorative window frame panel 5. Simultaneously, connectors 52, which can be adhesive tape, are attached to the front and rear ends of the decorative window frame panel 5 along the X direction. The adhesive tape, in conjunction with the mounting bracket 51, secures the decorative window frame panel 5 to the outer window frame panel 1. In some embodiments, the mounting bracket 51 may be located among the plurality of connectors 52; in some embodiments, the mounting bracket 51 and the plurality of connectors 52 may be arranged sequentially.
[0063] Figure 6 This is a schematic diagram of the assembly of the waterproof sealing strip 7 according to the present invention; Figure 7 This is a schematic diagram of the assembly of the joint sealing strip 6 shown in this invention.
[0064] In some other embodiments, the door structure also includes a sealing assembly, see [link to relevant documentation]. Figure 2 , Figure 6 and Figure 7 The sealing assembly includes:
[0065] Door sealing strip 8 and door frame sealing strip 9 are respectively connected to the side wall of the inner panel 2 of the window frame to seal the gap between the inner panel 2 of the window frame and the side components of the vehicle; waterproof sealing strip 7 is connected to the outer panel 1 of the window frame to seal the space between the outer panel 1 of the window frame and the door glass 3; joint sealing strip 6 is connected to the side wall of the outer panel 1 of the window frame and is located between the door glass 3 and the window frame decorative panel 5 to seal the gap between the door glass 3 and the window frame decorative panel 5. Further, a steel strip is embedded inside the waterproof sealing strip 7, and the side wall of the waterproof sealing strip 7 has a waterproof sealing strip lip 71, a waterproof sealing strip blister 72 and a waterproof sealing strip awning 73. A groove is formed between the waterproof sealing strip lip 71 and the waterproof sealing strip blister 72, and the waterproof sealing strip awning 73 is movably abutted against the outer panel 1 of the window frame.
[0066] In this embodiment, the sealing assembly is installed on the outer window frame panel 1 and the inner window frame panel 2, respectively, and makes contact with the door glass 3 to achieve a sealing and waterproofing effect on the door. The side components can be the side panel. The compressed tubing of the door frame sealing strip 9 forms a sealing structure with the inner window frame panel 2, which can reduce noise. The door sealing strip 8 and the door frame sealing strip 9 are similar to traditional designs and have high structural versatility. It should be understood that the structures of the door sealing strip 8 and the door frame sealing strip 9 are known technologies; for clarity and brevity, specific descriptions of their known functions and structures are omitted herein.
[0067] In this embodiment, the joint sealing strip 6 is adhered to the side wall of the outer panel 1 of the window frame using a second adhesive tape 61. The joint sealing strip 6 is a single-lip adhesive strip with a "Z" shape at a certain angle. The joint sealing strip 6 can be adhered to the joint sealing strip mounting surface 16 using the second adhesive tape 61. The joint sealing strip mounting surface 16 is roll-formed to achieve an ideal mounting surface, avoiding the influence of the stamping die angle. Therefore, after the joint sealing strip 6 is matched and compressed with the glass, it can better seal the gap between the glass and the window frame decorative panel 5, resulting in a better zero-step difference effect. The second adhesive tape 61 can be referred to in the description of the first adhesive tape 31.
[0068] The waterproof sealing strip 7 has a built-in steel strip for reliable clamping and to prevent it from falling off. The lip 71 of the waterproof sealing strip is compressed and adheres to the glass. A groove is formed between the lip 71 and the bubble tube 72 of the waterproof sealing strip to ensure that even if water passes over the bubble tube 72, it will not enter the visible area of the interior. In some embodiments, the bubble tube 72 of the waterproof sealing strip adopts a bubble tube structure, which can increase the contact area between the sealing strip and the door glass 3, and achieve better waterproofing. The waterproof sealing strip awning 73 can be designed with a slight amount of interference with the outer panel 1 of the window frame. After compression, it can adhere tightly to the outer panel 1 of the window frame, achieving a better appearance and improving the sealing and waterproofing performance.
[0069] In summary, the embodiments of the present invention use a roll forming structure to design structural features on the outer panel 1 of the window frame that match the guide groove 4, so that the outer surface of the door glass 3 and the outer surface of the window frame decorative panel 5 are in a state of zero surface difference. The required state is achieved with an extremely simple structure, the assembly is simple, and the purpose of reducing wind noise and improving the appearance is achieved.
[0070] The second objective of this embodiment is to provide an automobile equipped with a zero-step door structure with roller stamping as described above.
[0071] For the automotive embodiment of the present invention, since it is basically similar to the embodiment of the zero-step difference door structure combined with roll forming, the description is relatively simple, and relevant parts can be referred to in the description of the method embodiment.
[0072] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
[0073] It should also be noted that, in this document, the terms "upper," "lower," "left," "right," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, 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, and therefore should not be construed as a limitation of the invention.
