Description

Technical Field

[0001] This utility model relates to the field of window frame structure technology, specifically to a rubber strip corner joint, a window frame decorative component, and a car door. Background Technology

[0002] To achieve a higher level of quality and luxury, decorative trim strips for car door and window frames are typically made of aluminum alloy. Due to the strength and thickness of the aluminum alloy trim strips, a separate anodizing process is required. Consequently, the decorative trim strips and the glass guide strips used to install them are often connected by a post-assembly snap-fit ​​method. The glass guide strips are composed of components such as strip corner joints, vertical strips, and horizontal strips.

[0003] The corner joint of a window frame is typically located at the corner and includes the joint body and a positioning insert for mounting the joint body to the window frame sheet metal. During assembly, the positioning insert is usually first installed and fixed onto the joint body, and then the positioning insert and the joint body are molded together to form a complete corner joint structure, which is then assembled onto the window frame sheet metal. In existing technology, the positioning insert is generally used to ensure the installation and positioning of the corner joint with the window frame sheet metal. For aluminum alloy translucent strips, the corner joint is mainly used for installation and positioning. However, there can be a certain positioning error between the positioning insert and the window frame sheet metal, and there can also be a certain positioning error between the aluminum alloy translucent strip and the corner joint. This results in a significant accumulation of positioning tolerances during assembly, ultimately leading to poor assembly consistency of the aluminum alloy translucent strip.

[0004] Therefore, it is necessary to improve the joint structure of the existing glass guide groove adhesive strip to effectively reduce the cumulative positioning error during the installation of decorative bright strips and ensure the assembly consistency between decorative bright strips. Utility Model Content

[0005] In view of this, the present invention provides a rubber strip corner connector, a window frame decorative component, and a car door. By improving the structure of the rubber strip corner connector, the corner insert can simultaneously assemble and position the window frame sheet metal and the decorative bright strip, thereby reducing the cumulative positioning error when assembling the glass guide groove rubber strip with the window frame sheet metal and with the decorative bright strip, and ensuring the assembly consistency of the decorative bright strip.

[0006] The adhesive strip corner provided by this utility model is used to install on the glass guide groove adhesive strip at the corner where the window frame sheet metal connects to the body pillar. The adhesive strip corner includes a corner body and a corner insert disposed in the corner body. The corner insert has a first positioning part for positioning and cooperating with the window frame sheet metal in the body length direction and a second positioning part for positioning and cooperating with the decorative bright strip in the body length direction.

[0007] Furthermore, the corner body is provided with an installation part near the connecting corner. After the corner body and the corner insert are molded by injection molding, the top surface of the installation part is flush with the top surface of the second positioning part, and the installation part and the second positioning part are spliced ​​together to form an installation platform for installing decorative bright strips.

[0008] Furthermore, the mounting platform has a mounting surface on the rear side in the length direction of the vehicle body. The mounting surface is conformally arranged to the end edge of the decorative bright strip in the length direction. During installation, the end edge of the decorative bright strip abuts against the mounting surface and positions the decorative bright strip in the length direction of the vehicle body.

[0009] Furthermore, the mounting platform is provided with snap-fit ​​grooves at both ends in the height direction of the vehicle body, and the decorative bright strip is provided with snap-fit ​​parts in the width direction. The decorative bright strip is installed and positioned in the width direction and height direction of the vehicle body by snap-fitting the snap-fit ​​parts with the snap-fit ​​grooves.

[0010] Furthermore, the corner bracket body is provided with a positioning hole that is installed and cooperates with the first positioning part. After the first positioning part is connected to the positioning hole, the corner bracket insert is installed and positioned on the corner bracket body.

[0011] Furthermore, the window frame sheet metal is provided with a positioning groove for cooperating with the first positioning part. After the first positioning part passes through the positioning hole, it connects with the positioning groove to realize the positioning of the rubber strip corner and the window frame sheet metal in the length direction of the vehicle body.

[0012] Furthermore, the outer side of the corner body is provided with an assembly indicator point for visual assembly, and the assembly indicator point coincides with the position of the positioning hole in the longitudinal projection.

[0013] Furthermore, the corner insert is provided with positioning posts for installing and positioning the mold during the corner body compression molding process, and a plurality of positioning posts are spaced apart on both sides of the vehicle body width direction along the length direction of the corner insert.

[0014] A window frame decorative component includes a glass guide strip installed on the window frame sheet metal and a decorative bright strip disposed on the glass guide strip, wherein the glass guide strip has the aforementioned strip corner joint at the corner where the window frame sheet metal connects to the vehicle body pillar.

[0015] A vehicle door, wherein the aforementioned window frame decorative assembly is provided on the vehicle door.

[0016] The beneficial effects of this utility model are as follows: In the corner joint, window frame decorative component, and car door provided by this utility model, the decorative bright strip can be directly positioned on the window frame sheet metal through the corner insert, eliminating the cumulative positioning tolerance problem caused by the length tolerance of the rubber strip and the softness of the corner rubber, and achieving higher dimensional accuracy control in the length direction of the vehicle body; the decorative bright strip can be positioned in the height direction and width direction of the vehicle body through the second positioning part on the corner insert, and the small overlap can be designed for zero-fit fit, while the corner insert can also serve as a hard reference to achieve higher surface profile accuracy in the height direction and width direction of the vehicle body; at the same time, the top surface of the insert is fitted to the inner surface of the decorative bright strip, which is conducive to improving the assembly consistency of the decorative bright strip.

Detailed Implementation

[0027] As shown in the figure, the adhesive strip corner joint provided by this utility model is used to install on the glass guide channel adhesive strip at the corner where the window frame sheet metal connects to the body pillar. The adhesive strip corner joint includes a corner joint body 3 and a corner joint insert 4 disposed within the corner joint body 3. The corner joint insert 4 has a first positioning part 401 for positioning and cooperating with the window frame sheet metal in the body length direction and a second positioning part 402 for positioning and cooperating with the decorative bright strip 1 in the body length direction. The glass guide channel adhesive strip is widely used in automotive door and window frame systems, mainly for the guide channel part of the window glass, playing a role in sealing, shock absorption, noise reduction, guiding the glass lifting and lowering, and decoration. The adhesive strip corner joint is where the glass guide channel adhesive strip is installed in the B-pillar and C-pillar areas of the door. The components at the corners of the glass guide channels are mainly used to connect the sealing strips in the horizontal and vertical glass guide channels, and are fixed to the corners of the car door and window frames through limiting structures or barbed structures. In the existing technology, when assembling the rubber strip corner, the corner insert 4 is first installed and fixed on the corner body 3, and then the corner insert 4 and the corner body 3 are molded together to form an integral rubber strip corner structure. Finally, the rubber strip corner is assembled onto the window frame sheet metal, while the decorative bright strip 1 is directly assembled onto the rubber strip corner. However, due to the influence of rubber strip length tolerance and the relatively softness of the corner after molding, the positioning tolerance is prone to accumulate, which ultimately leads to poor assembly effect of the decorative bright strip 1 in the length direction of the car body, affecting the overall aesthetics. In this solution, by setting a first positioning part 401 that cooperates with the window frame sheet metal and a second positioning part 402 that cooperates with the decorative bright strip 1 on the corner insert 4, the corner insert 4 can directly install and position the window frame sheet metal and the decorative bright strip 1 at the same time. This allows the decorative bright strip 1 to be directly positioned on the window frame sheet metal in the length direction of the vehicle body, reducing manufacturing and assembly tolerances, eliminating the cumulative positioning tolerance problem caused by the rubber strip length tolerance and the softness of the corner rubber, and achieving higher dimensional accuracy control in the length direction of the vehicle body.

[0028] In this embodiment, the corner bracket body 3 is provided with a mounting part 301 at the end near the vehicle body pillar. The mounting part 301 and the second positioning part 402 are spliced ​​together to form a mounting platform for installing the decorative bright strip 1. In this embodiment, the vehicle body pillar is described as the B-pillar of the door. The rubber strip corner is located at the corner of the glass guide groove in the B-pillar area of ​​the door. Figure 1 and Figure 2As shown, a mounting part 301 is provided on the corner body 3, and a second positioning part 402 is also provided on the corner insert 4. After the corner body 3 and the corner insert 4 are installed and fixed, the mounting part 301 and the second positioning part 402 are spliced ​​together to form an installation platform for positioning the decorative bright strip 1. The decorative bright strip 1 is then mounted on the glass guide strip at the end near the B-pillar of the car door through this installation platform. The mounting part 301 and the second positioning part 402 can be connected by fastening, overlapping or snapping. In this embodiment, the top of the mounting part 301 is provided with a notch, and the top of the second positioning part 402 can fill the notch and form a complete installation platform together with the top of the mounting part 301. The bottom of the corner insert 4 is connected to the bottom of the corner body 3 by overlapping. The top of the mounting part 301 and the top of the second positioning part 402 are both ends facing outwards.

[0029] In this embodiment, after the corner body 3 and the corner insert 4 are molded and injection molded to form an integral structure, the top surface of the mounting part 301 is flush with the top surface of the second positioning part 402; wherein the top surface of the mounting part 301 is the outer surface of the end of the mounting part 301 facing the outside of the vehicle, and the top surface of the second positioning part 402 is the outer surface of the end of the second positioning part 402 facing the outside of the vehicle, that is, the outer surfaces that are in close contact with the inner surface of the decorative bright strip. Since the traditional corner insert 4 is installed and positioned with the corner body 3 by means of a pin, although it is convenient for workers... Assembly is required, but after assembly, the outer surfaces of the corner insert 4 and the corner body 3 that are used to tightly adhere to the decorative bright strip 1 are prone to unevenness, which leads to inconsistent adhesion between the two ends of the decorative bright strip 1 and the glass guide groove adhesive strip. One end is prone to lifting up, affecting the overall aesthetics. By setting the top surface of the mounting part 301 flush with the top surface of the second positioning part 402, the inner surface of the end of the decorative bright strip 1 can tightly adhere to the top surface of the mounting part 301 and the top surface of the second positioning part 402, ensuring the installation and positioning accuracy of the corner insert 4 for the decorative bright strip 1.

[0030] When the existing corner bracket body 3 is assembled onto the window frame sheet metal, a physical snap-fit ​​method within the mounting groove is typically used to ensure the bonding strength between the corner bracket body 3 and the window frame sheet metal. However, in this embodiment, to improve the bonding strength between the corner bracket body 3 and the window frame sheet metal and prevent the corner bracket body 3 from falling off, a tight-fitting block 304 structure for enhancing friction strength is also provided in the mounting groove where the corner bracket body 3 is installed onto the window frame sheet metal (see...). Figure 2 The 304 structure of the close-fitting block can be multiple blocks or set as a single block, depending on the application.

[0031] In this embodiment, the mounting platform has a mounting surface 405 on its rear side along the length of the vehicle body. The mounting surface 405 is conformally arranged to the end edge of the decorative bright strip 1 along its length. During installation, the end edge of the decorative bright strip 1 abuts against the mounting surface 405 and positions the decorative bright strip 1 along the length of the vehicle body. Figure 6 and Figure 7 As shown, the end of the decorative bright strip 1 in the length direction is usually provided with an edge-wrapping structure. Therefore, in order to ensure the positioning of the decorative bright strip 1 in the length direction of the vehicle body by the mounting platform, an mounting surface 405 is provided on the rear side of the mounting platform in the length direction of the vehicle body and is set in accordance with the edge-wrapping of the end of the decorative bright strip 1 in the length direction. This allows the edge-wrapping of the end of the decorative bright strip 1 in the length direction to abut against the mounting surface 405 during installation. Part of the mounting surface 405 is the end face of the second positioning part 402. Therefore, the positioning of the decorative bright strip 1 by the second positioning part 402 in the length direction of the vehicle body is realized, thereby realizing the positioning of the decorative bright strip 1 by the corner insert 4 in the length direction of the vehicle body.

[0032] In this embodiment, the mounting platform is provided with snap-fit ​​grooves 404 at both ends in the vehicle height direction, and the decorative bright strip 1 is provided with snap-fit ​​parts 101 in the width direction. The decorative bright strip 1 is installed and positioned in the vehicle width direction and vehicle height direction by snap-fitting the snap-fit ​​parts 101 with the snap-fit ​​grooves 404; combined with Figures 3 to 5 As shown, the decorative trim strip 1 typically has a snap-fit ​​portion 101 in the width direction, which is existing technology and will not be described in detail here. Therefore, the mounting platform has snap-fit ​​grooves 404 at both ends in the vehicle height direction that mate with the snap-fit ​​portion 101. Since the traditional structure involves the decorative trim strip 1 being snapped onto the rubber strip mushroom head structure via the snap-fit ​​portion 101, and given the relatively soft nature of rubber, and the need to ensure the assemblability of the decorative trim strip 1, it is necessary to design a gap match between the decorative trim strip 1 and the rubber strip joint. This results in the rubber strip joints in both the vehicle height and width directions being... The unstable contour surface of the trim strip corner poses a risk of detachment. In this solution, the soft reference of the rubber strip at the end of the trim strip corner 1 in the B-pillar area is changed to a hard reference. Specifically, the corner body 3 and corner insert 4 are made of hard materials such as PA6+GF and used as positioning references in the width and height directions of the vehicle body to provide effective hard positioning. Due to the small overlap, it is convenient for assembly and can also effectively improve the surface contour of the trim strip corner 1 in the width and height directions of the vehicle body.

[0033] In this embodiment, the corner connector body 3 is provided with a positioning hole 302 that mates with the first positioning part 401. After the first positioning part 401 is connected to the positioning hole 302, the corner connector insert 4 is installed and positioned on the corner connector body 3. Figure 1 and Figure 2 As shown, in addition to the normal overlapping relationship between the corner body 3 and the corner insert 4, it is also necessary to ensure the positioning accuracy between the two. Therefore, the corner body 3 is provided with a positioning hole 302 that is installed and cooperates with the first positioning part 401, so that the installation accuracy between the corner body 3 and the corner insert 4 is high, thereby ensuring the assembly accuracy of the subsequent decorative bright strip 1.

[0034] In this embodiment, the window frame sheet metal is provided with a positioning groove 5 for cooperating with the first positioning part 401. After the first positioning part 401 passes through the positioning hole 302, it connects with the positioning groove 5 to realize the positioning of the rubber strip corner and the window frame sheet metal in the length direction of the vehicle body; combined with Figure 1 , Figure 3 and Figure 4 As shown, the first positioning part 401 on the corner insert 4 extends outward after passing through the positioning hole 302 until it is inserted into the positioning groove 5 on the window frame sheet metal, so as to realize the positioning between the corner insert 4 and the window frame sheet metal, thereby realizing the positioning of the rubber strip corner and the window frame sheet metal in the length direction of the vehicle body. In this solution, the window frame sheet metal specifically refers to the window frame reinforcing plate 2.

[0035] In this embodiment, an assembly indicator point 303 for visual assembly is provided on the outer side of the corner body 3. The assembly indicator point 303 coincides with the positioning hole 302 in the longitudinal projection. Since the positioning hole 302 will be covered and disappeared by the injection molding material after the corner body 3 and the corner insert 4 are molded into a whole, in order to facilitate visual assembly by workers, an assembly indicator point 303 is provided on the outer side of the corner body 3 at a cross-sectional position in the same body length direction as the positioning hole 302, thereby ensuring the installation accuracy of the rubber strip corner and improving the assembly consistency of the decorative bright strip 1.

[0036] In this embodiment, the corner insert 4 is provided with positioning posts 403 for mounting and positioning the mold during the injection molding of the corner body 3; a plurality of positioning posts 403 are spaced apart on both sides of the vehicle body width direction along the length direction of the corner insert 4; combined with Figure 3 and Figure 8 As shown, in order to ensure the quick installation and positioning of the mold, a positioning post 403 structure is provided on the corner insert 4. In order to ensure the molding quality of the corner insert 4 and the corner body 3 during the mold closing injection process, several positioning posts 403 are arranged at intervals along the length direction of the corner insert 4 on both sides of the vehicle body width direction to improve the molding quality of the rubber strip corner. At the same time, the outer end face of the positioning post 403 is usually flush with the outer end face of the rubber strip corner after the mold closing injection.

[0037] This embodiment also provides a window frame decorative component, including a glass guide strip installed on the window frame sheet metal and a decorative bright strip 1 disposed on the glass guide strip. The glass guide strip has a strip corner at the corner where the window frame connects to the vehicle body pillar. By using this window frame decorative component, the superposition of positioning errors generated during the assembly process of the decorative bright strip 1 can be reduced, and higher surface contour accuracy of the decorative bright strip 1 in the vehicle height direction and vehicle width direction can be achieved.

[0038] This embodiment also provides a car door, on which the above-mentioned window frame decorative component is provided; by providing the window frame decorative component on the car door, the gap consistency of the decorative bright strip 1 between the front and rear car doors can be well ensured, and the overall aesthetics of the decorative bright strip 1 on the car door can be effectively improved.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
