Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, specifically to a connection structure between a side triangular window and a side decorative strip. Background Technology

[0002] Currently, due to manufacturing process, aerodynamic, and design aesthetic requirements, metallic trim strips are often installed on the rear quarter window and upper side panels of vehicle bodies. These strips serve sealing, airflow guidance, and aesthetic purposes, while also conveying a sense of luxury and sophistication. However, the side quarter window trim strip and the side panel trim strip differ significantly in molding process, installation method, and placement space. The side quarter window trim strip is typically formed using a stamping process, pressed onto the side panel sheet metal from the Y-axis of the vehicle using clips. The side panel trim strip, on the other hand, is usually extruded, inserted from the A-pillar and extending to the C-pillar to match the rear quarter window, achieving overall design consistency. Due to inherent manufacturing tolerances, excessively long side panel trim strips, limited space leading to a lack of effective fixing structures, and the influence of stress deformation on the side panel, can easily cause movement at the joint between the end of the trim strip and the quarter window after assembly. This can result in surface defects and gaps, affecting the vehicle's overall aesthetic appeal.

[0003] To address the aforementioned issues, some side-mounted triangular window products design the metal connecting pieces to be glued, welded, or screwed to the ends of the side-mounted triangular window decorative strips, such as CN216915741U and CN116620177A. However, this design also brings problems such as the inability to adhere firmly, easy detachment, and poor connection rigidity. Utility Model Content

[0004] This utility model provides a connection structure between a side triangular window and a side decorative strip, which can overcome the problems of difficult installation and poor consistency of existing products, and has the advantages of convenient assembly, high reliability and good matching.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A connection structure between a side triangular window and a side decorative strip includes a side triangular window decorative strip, a side decorative strip, an injection-molded edging, and a connecting piece;

[0007] The side triangular window decorative strip is installed on the injection-molded edging, and the side decorative strip is spliced ​​with the side triangular window decorative strip through connecting pieces;

[0008] The connecting piece head end is composed of an installation guide surface, an installation mating surface, and a mold positioning surface in sequence. The mold positioning surface is provided with an injection mold positioning hole, and the connecting piece end is provided with independent top surface fixing feet and side fixing feet.

[0009] The top fixing feet and side fixing feet are integrally wrapped around the injection molding edge during injection molding. The installation guide surface, installation mating surface, and mold positioning surface are inserted into the side decorative strip in sequence during installation to complete the assembly.

[0010] Furthermore, the top fixing foot is located behind the mold positioning surface, and the side fixing foot is located behind the mounting mating surface.

[0011] Furthermore, both the top fixing foot and the side fixing foot are arranged in a Z-shaped corner configuration.

[0012] Compared with the prior art, the advantages and effects of this utility model are:

[0013] 1. Compared with the traditional design of bonding or welding metal connecting pieces, the design of using fixing feet to integrally injection mold the connecting pieces is more secure and less likely to fall off. Moreover, the position is more accurate and the connection rigidity is better, which reduces assembly time and manufacturing costs.

[0014] 2. Because the connecting piece is rigid and strong at the end, even if there is some misalignment in the side decorative strip on the end face, it will be corrected and compensated after the connecting piece is inserted, so as to achieve the matching of the side triangular window decorative strip with the side decorative strip and make up for gaps and surface differences.

[0023] The present invention will be further described below with reference to the embodiments, but the present invention is not limited to these embodiments.

[0024] This embodiment describes a connection structure between a side triangular window and a side decorative strip, such as... Figure 1 and 2 As shown, it includes a side triangular window decorative strip 2, a side decorative strip 4, an injection-molded edging 5, and a connecting piece 6. The side triangular window decorative strip 2 is installed on the injection-molded edging 5, and the side decorative strip 4 is spliced ​​to the side triangular window decorative strip 2 through the connecting piece 6.

[0025] like Figure 3 As shown, a fixing tape 7 and a fixing clip 8 are provided under the side triangular window decorative strip 2. The fixing tape 7 is used to accurately fix the side triangular window decorative strip 2 to the injection molding edge 5 to prevent it from moving. The fixing clip 8 is used to prevent the side triangular window decorative strip 2 from loosening.

[0026] like Figure 4 As shown, the head end of the connecting piece 6 is composed of an installation guide surface 61, an installation mating surface 62, and a mold positioning surface 63. The mold positioning surface 63 is provided with an injection mold positioning hole 64 for accurate positioning of the connecting piece 6 in the injection mold. The end of the connecting piece 6 is provided with two independent fixing feet arranged in a Z-shaped corner. The top fixing foot 65 is located behind the mold positioning surface 63, and the side fixing foot 66 is located behind the installation mating surface 62. The two fixing feet are used to increase the contact area between the connecting piece 6 and the injection molding edge 5 to ensure that the connecting piece 6 has sufficient rigidity at the end of the side triangular window.

[0027] In this embodiment, the side triangular window decorative strip 2 is made of stainless steel SUS430MA stamping and the surface is electrophoretic painted; the side decorative strip 4 is made of aluminum extrusion; the injection molded edging 5 is made of PVC with a hardness of 75 degrees; the connecting piece 6 is made of metal and is made of stainless steel sheet B442D stamping.

[0028] The working principle of this utility model is as follows:

[0029] 1. The injection-molded edging 5 uses the side triangular window glass 1, connecting piece 6, and sealing strip to fix the guide rail 9 as an insert, and completes the PVC integral injection molding in the mold. The two fixing feet of the connecting piece 6 are integrally wrapped around the ends of the injection-molded edging 5 during injection molding, such as... Figure 5 , 6 As shown;

[0030] 2. Install the side triangular window decorative strip 2 onto the side triangular window (injection-molded edging 5) using an assembly machine;

[0031] 3. During installation, first insert the mounting guide surface 61 of the connecting piece 6 into the mounting mating body 41 of the side decorative strip 4, then slowly slide it in until the mounting mating surface 62 and the mounting mating body 41 are in contact to complete the assembly. Figure 7 As shown.
