Description

Technical Field

[0001] This application belongs to the field of automotive door corner window technology, and particularly relates to a support structure for automotive door corner windows, a car door, a vehicle, and a method for installing the car door. Background Technology

[0002] Currently, rear door corner windows on the market fall into two categories: integrated corner windows with guide channels and corner windows without guide channels. Corner windows with guide channels generally consist of the following components: guide channels, tempered glass, positioning pins, and adhesive. The guide channels, tempered glass, and positioning pins are wrapped in adhesive and bonded together to form a single unit. This type of corner window is installed with the door corner window support structure mounted in the Z-axis direction, pre-installed on the door using Y-axis positioning pins, and then secured with several Y-axis mounting screws. Corner windows without guide channels generally consist of the following components: positioning inserts, tempered glass, positioning pins, and adhesive. The tempered glass, positioning pins, and positioning inserts are wrapped in adhesive and bonded together to form a single unit. This type of corner window generally has two installation methods: semi-split doors typically have the door corner window support structure mounted in the Y-axis direction, while roll-fitted window frames and integrated doors often use a platform perpendicular to the Z-axis added to the window sill to assemble the corner window.

[0003] The existing corner window installation support structure requires additional parts, such as corner windows with guide channels and installation brackets, which results in higher costs and increased weight. In addition, it also limits the welding structure. Therefore, the corner window support structure needs to be further optimized. Summary of the Invention

[0004] This application aims to solve the technical problem of cost of corner window support structure to at least a certain extent. To this end, this application provides a door corner window support structure, a door, a vehicle and a method for installing the door, which can install a Z-direction support corner window on the door, effectively reduce the cost of the entire door while maintaining the same installation effect, and also reduce the weight and optimize the welding process.

[0005] In a first aspect, embodiments of this application provide a door corner window support structure, applied to a door including an outer panel and an inner panel, the door corner window support structure comprising:

[0006] The outer reinforcing plate is connected to the outer plate on one side, and a portion of the other side is turned inward to form an outwardly turned-out edge.

[0007] The inner reinforcing plate is connected to the inner plate on one side, and a portion of the other side is turned outwards to form an inwardly turned-out edge.

[0008] The outer flange and the inner flange are stacked so that the outer reinforcing plate and the inner reinforcing plate form a U-shaped groove for the corner window to be embedded. The inner flange and the outer flange are connected to form the bottom of the U-shaped groove, which is used to support the corner window in the Z direction.

[0009] In an optional embodiment, both the outer flange and the inner flange are provided with concave and convex shapes. The outer flange and the inner flange are connected to form a support area and a connecting area. The outer flange and the inner flange fit together at the location of the connecting area to connect and fix them. The outer flange and the inner flange form a cavity at the location of the support area.

[0010] In an optional embodiment, the outer flange is provided with concave and convex sections to form multiple sets of concave and convex sections, which are arranged alternately along the length of the U-shaped groove. The inner flange is provided with concave and convex sections to form multiple sets of concave and convex sections, which are arranged alternately along the length of the U-shaped groove.

[0011] In an optional embodiment, the outer flange is stacked on top of the inner flange, the outer concave section and the inner convex section are fitted together to form a connecting area, and there is a cavity between the outer convex section and the inner concave section to form a support area.

[0012] In an optional embodiment, along the width direction of the U-shaped groove, the dimensions of the outer concave section, the outer convex section, the inner concave section, and the inner convex section are greater than or equal to the dimensions of the overlapping area of ​​the outer flange and the inner flange.

[0013] Secondly, embodiments of this application provide a car door, which includes an outer panel, an inner panel, and the aforementioned car door corner window support structure.

[0014] In an optional embodiment, the outer plate covers and fixes the edge of the outer reinforcing plate, the inner plate is welded and fixed to the edge of the inner reinforcing plate, and the outer flange is stacked on top of the inner flange.

[0015] Thirdly, embodiments of this application provide a vehicle that includes the aforementioned door.

[0016] Fourthly, embodiments of this application provide an installation method for the aforementioned vehicle door, comprising:

[0017] Weld the inner reinforcing plate to the inner plate and connect the outer reinforcing plate to the outer plate;

[0018] Adjust the relative positions of the outer and inner panels so that the outer flange and the inner flange overlap.

[0019] Insert the welding tool into the U-shaped groove, and using the U-shaped groove as the operating space, weld and fix the outer flange and the inner flange along the Z direction inside the U-shaped groove.

[0020] In an optional embodiment, when both the outer flange and the inner flange are provided with concave and convex shapes, and the outer flange and the inner flange are connected to form a support area and a connecting area, the outer flange and the inner flange are welded and fixed, specifically including: welding only in the connecting area.

[0021] As can be seen from the above technical solution, the beneficial effects of this application are as follows:

[0022] 1. The support structure of this application utilizes the outer and inner reinforcing plates by designing the outer and inner reinforcing plates with flanges. The outer and inner flanges are stacked and connected to form a U-shaped groove and the bottom of the U-shaped groove that can provide Z-direction support for the corner window. This eliminates the need for a separate guide groove structure, saves the guide groove installation process, and eliminates the need for a support frame. It allows for the installation of Z-direction support corner windows on the car door while maintaining the same installation effect. This effectively reduces the cost of the entire car door, reduces weight, and optimizes the welding process.

[0023] 2. The door of this application, by adopting the above-mentioned support structure and utilizing the reinforcing plate between the outer panel and the inner panel, provides a base for installing the corner window, eliminating the need for the guide groove structure and mounting bracket, thereby reducing production costs and weight.

[0024] 3. The vehicle described in this application, by adopting the aforementioned door, can be equipped with the same corner windows, while reducing production costs and weight to a certain extent.

[0025] 4. The processing method of this application eliminates the steps of installing guide grooves and support frames in the existing corner window installation process. By connecting the outer reinforcing plate to the outer panel and the inner reinforcing plate to the inner panel, a connection base is formed with the outer and inner panels. Then, by welding the outer and inner flanges together, a U-shaped groove for installing the corner window is directly formed, which optimizes the existing process. At the same time, since the U-shaped groove serves as the welding operation space and can be directly connected to the inner and outer panels, it is no longer necessary to leave a height difference between the inner and outer window sills, thus optimizing the welding process.

[0040] This application is described below with reference to the accompanying drawings and specific embodiments:

[0041] Please refer to Figure 1 and Figure 2 According to a first aspect of this application, a corner window support structure for a vehicle door is provided, applied to a vehicle door 500 including an outer panel 300 and an inner panel 400. The outer panel 300 and the inner panel 400 are respectively the outer and inner panel structures of the vehicle door 500. The corner window support structure of the vehicle door 500 is connected to the outer panel 300 and the inner panel 400, and includes an outer reinforcing plate 100 and an inner reinforcing plate 200. The outer reinforcing plate 100 is attached to the side of the outer panel 300 in the X direction, and the inner reinforcing plate 200 is attached to the side of the inner panel 400 in the X direction. The outer reinforcing plate 100 and the inner reinforcing plate 200 are respectively located between the outer plate 300 and the inner plate 400. One side of the outer reinforcing plate 100 is connected to the outer plate 300. If the edge of the outer plate 300 is folded over, it will cover and press the edge of the outer reinforcing plate 100 tightly. A portion of the other side will be turned towards the inner plate 400 to form an outwardly turned-over edge 110. For example, the outer reinforcing plate 100 will be turned towards the inner reinforcing plate 200 in the area corresponding to the corner window 510. One side of the inner reinforcing plate 200 is connected to the inner plate 400. The edge is welded to the edge of the inner panel 400, and a portion of the other side is flanged towards the outer panel 300 to form an inner flange 210. For example, the inner reinforcing plate 200 is flanged towards the outer reinforcing plate 100 in the corresponding portion of the corner window 510. The outer flange 110 and the inner flange 210 are perpendicular to the Z-direction. The outer flange 110 and the inner flange 210 are stacked, with the outer flange 110 stacked on top of the inner flange 210. The outer flange 110 is used to support the corner window 510; or the inner flange 210 is stacked on top of the outer flange 110. The inner flange 210 is used to support the corner window 510. They are stacked so that the outer reinforcing plate 100 and the inner reinforcing plate 200 form a U-shaped groove for the corner window 510 to be inserted. The width of the U-shaped groove matches the thickness of the corner window 510 so that the corner window 510 can be inserted into the U-shaped groove. The inner flange 210 and the outer flange 110 are connected to form the bottom of the U-shaped groove. The inner flange 210 and the outer flange 110 can be connected by welding, bolting or other convenient fixing methods. The bottom of the U-shaped groove is used to support the corner window 510 in the Z direction.

[0042] Existing corner windows have some issues with high installation costs. For example, corner windows with guide channels are relatively expensive due to the guide channel structure and soft adhesive bonding. Corner windows without guide channels require mounting brackets to support the window sill, and the movable guide rail is fixed to the guide roller and inner panel 400, which also increases costs. In addition, this type of corner window has a height difference between the inner and outer window sill edges due to welding, which does not meet the requirements of some vehicle models. This application utilizes the flanged design of the outer reinforcing plate 100 and the inner reinforcing plate 200, and combines the outer flanged portion 110 and the inner flanged portion 210 by stacking and connecting them to form a U-shaped groove and the bottom of the U-shaped groove that can provide Z-direction support for the corner window 510. This eliminates the need for a separate guide groove structure, saves the guide groove installation process, and eliminates the need for a support frame. The Z-direction support corner window 510 can be installed on the door 500 while maintaining the same installation effect. This effectively reduces the cost of the entire door 500, reduces weight, and optimizes the welding process.

[0043] Please refer to Figure 3 and Figure 4In an optional embodiment, both the outer flange 110 and the inner flange 210 are convex and concave, meaning that the surfaces of the outer flange 110 and the inner flange 210 have recessed and protruding positions. The outer flange 110 and the inner flange 210 are connected to form a support area and a connecting area. The support area and the connecting area are formed by stacking uneven structural forms. The support area and the connecting area combine to form the overlapping area of ​​the outer flange 110 and the inner flange 210. 10 are fitted together at the connection area, that is, the outer flange 110 and the inner flange 210 are tightly attached together at the connection area to facilitate connection and fixation during construction. Welding, riveting or other fixing methods are preferred. The outer flange 110 and the inner flange 210 form a cavity at the support area. That is, in the support area, there is a gap between the corresponding parts of the outer flange 110 and the inner flange 210. This gap allows the outer flange 110 and the inner flange 210 to form a cavity after being stacked. In an optional embodiment, multiple sets of concave segments 111 and convex segments 112 extend along the width direction of the U-shaped groove on the outer flange portion 110, i.e., along the Y direction. Similarly, multiple sets of concave segments 211 and convex segments 212 extend along the width direction of the U-shaped groove on the inner flange portion 210, also along the Y direction. Along the Y direction, the dimensions of the concave segments 111, convex segments 112, concave segments 211, and convex segments 212 are greater than or equal to the dimensions of the overlapping area of ​​the outer flange portion 110 and the inner flange portion 210. This ensures that the entire overlapping area 600 of the outer flange portion 110 and the inner flange portion 210 is a concave-convex structure, providing better support for the corner window 510. This concave-convex arrangement prevents misalignment between the outer flange portion 110 and the inner flange portion 210, ensuring the accuracy of the overlapping area 600.

[0044] Please refer to Figure 5 , Figure 6 and Figure 7In an optional embodiment, the outer flange portion 110 is provided with concave and convex configurations to form multiple sets of concave segments 111 and convex segments 112. The concave segments 111 and convex segments 112 are arranged alternately along the length direction of the U-shaped groove. That is, during installation, the concave segments 111 and convex segments 112 are arranged alternately along the X direction. The inner flange portion 210 is provided with concave and convex configurations to form multiple sets of concave segments 211 and convex segments 212. The concave segments 211 and convex segments 212 are arranged alternately along the length direction of the U-shaped groove. That is, during installation, the concave segments 211 and convex segments 212 are arranged alternately along the X direction. When the above-mentioned alternating arrangement is adopted, the outer flange portion 110 and the inner flange portion 210 are always stacked to form a support area and a connection area. When the outer flange 110 is placed on the inner flange 210, the outer concave section 111 and the inner convex section 212 are correspondingly fitted together as a connecting area, and the outer convex section 112 and the inner concave section 211 are correspondingly spaced apart as a supporting area; when the inner flange 210 is placed on the outer flange 110, the outer convex section 112 and the inner concave section 211 are correspondingly fitted together as a connecting area, and the outer concave section 111 and the inner convex section 212 are correspondingly spaced apart as a supporting area. In an optional embodiment, the outward flange 110 is stacked on top of the inward flange 210, with the concave section 111 and the convex section 212 corresponding and fitting together to form a connection area. The convex section 112 and the concave section 211 are also corresponding, with a cavity between them to form a support area. In this configuration, the edge of the inner reinforcing plate 200 is welded and fixed to the inner plate 400, and the edge of the outer plate 300 is bent and covers and fixes the edge of the outer reinforcing plate 100. In this way, the convex section 112 of the outward flange 110 can support the corner window 510, ensuring that the quality of the weld points in the connection area is not affected and ensuring the stability of the structure.

[0045] Please refer to Figure 1 According to a second aspect of this application, a car door 500 is provided. The car door 500, as a whole, includes an outer panel 300, an inner panel 400, and the aforementioned car door corner window support structure. The outer reinforcing plate 100 and the inner reinforcing plate 200 also employ a flanged design, forming an outer flanged portion 110 and an inner flanged portion 210, respectively. The outer flanged portion 110 and the inner flanged portion 210 are arranged as described in the car door 500 corner window support structure. By adopting the aforementioned support structure, the car door 500 utilizes the reinforcing plate between the outer panel 300 and the inner panel 400 to provide a base for mounting the corner window 510, eliminating the need for a guide channel structure and mounting bracket, thus reducing production costs and weight. In an optional embodiment, the outer panel 300 is bent and then wrapped around and fixed to the edge of the outer reinforcing plate 100, and pressed and fixed. The edge of the inner panel 400 is welded and fixed to the edge of the inner reinforcing plate 200. The outer flange 110 is stacked on top of the inner flange 210, and the outer protruding section 112 of the outer flange 110 supports the diagonal window 510.

[0046] According to a third aspect of this application, a vehicle is provided, which includes the aforementioned door 500, and the outer reinforcing plate 100 and inner reinforcing plate 200 also adopt the aforementioned flange design. By adopting the aforementioned door 500, the vehicle can install the same corner window 510, while reducing production costs and weight to a certain extent.

[0047] Please refer to Figure 8 According to a fourth aspect of this application, an installation method for the aforementioned vehicle door 500 is provided, comprising:

[0048] S1. Weld the inner reinforcing plate 200 to the inner plate 400, and connect the outer reinforcing plate 100 to the outer plate 300. Specifically, first align the edge of the inner reinforcing plate 200 with the edge of the inner plate 400, so that the inner reinforcing plate 200 is located inside the inner plate 400, i.e., on the side facing the outer reinforcing plate 100. Then weld and fix the inner reinforcing plate 200 to the inner plate 400. After that, bend the edge of the outer plate 300 to cover the edge of the outer reinforcing plate 100, and press and fix it, so that the outer reinforcing plate 100 is fixed inside the outer plate 300, i.e., on the side facing the inner reinforcing plate 200. After the above steps, the inner reinforcing plate 200 and the inner plate 400 form an integral unit, and the outer reinforcing plate 100 and the outer plate 300 form an integral unit.

[0049] S2. Adjust the relative positions of the outer plate 300 and the inner plate 400 so that the outer flange 110 and the inner flange 210 are stacked. This step is called assembling. The outer plate 300 and the inner plate 400 are positioned opposite each other, and the outer flange 110 of the outer reinforcing plate 100 and the inner flange 210 of the inner reinforcing plate 200 are stacked to form a stacked state. The outer flange 110 can be stacked on top of the inner flange 210, or the inner flange 210 can be stacked on top of the outer flange 110. After the initial contact of the overlap, a stacked state along the Z direction is formed before welding.

[0050] S3. Insert the welding tool into the U-shaped groove, using the U-shaped groove as the operating space to ensure the passage of the welding torch. Weld the outer flange 110 and the inner flange 210 together along the Z-direction within the U-shaped groove. Specifically, the welding torch is inserted vertically into the U-shaped groove along the Z-direction, and welding is performed on the outer flange 110 and the inner flange 210 in the vertical direction. In an optional embodiment, when both the outer flange 110 and the inner flange 210 are convex and concave, and the outer flange 110 and the inner flange 210 are connected to form a support area and a connection area, welding the outer flange 110 and the inner flange 210 together specifically includes welding only in the connection area, while the outer flange 110 and the inner flange 210 in the support area remain in a non-welded state. After welding, the U-shaped groove of the outer reinforcing plate 100 and the inner reinforcing plate 200 is formed, and the bottom of the U-shaped groove provides support in the Z-direction.

[0051] When installing the corner window 510, push the corner window 510 into the glass guide rail and continue pushing it so that the corner window 510 enters the U-shaped groove and is supported and stabilized by the support area. Then, pass the movable guide rail through the through hole on the welded guide rail and adjust the movable guide rail so that the Z-direction mounting point at the upper end of the guide rail and the Y-direction mounting point at the lower end are aligned with the mounting holes on the inner panel 400. Then, install the movable guide rail onto the door 500 with bolts.

[0052] This application eliminates the steps of installing guide channels and support frames in the existing corner window installation process. By connecting the outer reinforcing plate 100 to the outer plate 300 and the inner reinforcing plate 200 to the inner plate 400, a connection base is formed with the outer plate 300 and the inner plate 400. Then, by welding the outer flange 110 and the inner flange 210 together, a U-shaped groove for installing the corner window 510 is directly formed, which improves the existing process. At the same time, since the U-shaped groove serves as the welding operation space and can be directly connected to the inner plate 400 and the outer plate 300, it is no longer necessary to leave a height difference between the inner and outer window sills, thus optimizing the welding process.
