[0002] In a vehicle's flat side door design, a slider is attached to the glass, and a guide rail is installed on the side of the door's B-pillar trim. The slider slides against the guide rail to raise and lower the glass, thereby constraining the glass in the X and Y directions. However, in existing designs, these guide rails often utilize rubber sealing strips, which are relatively soft and have large tolerance fluctuations. When the rubber sealing strip slides with the slider, the X and Y constraints on the glass are poor, resulting in unstable dimensional performance.
[0003] Therefore, it is urgent to develop a B-pillar decorative panel assembly and a vehicle. Utility Model Content
[0004] The inventors discovered that if the rubber sealing strip design of the guide rail is changed to a guide rail design made of hard material, although the guide rail made of hard material will provide strong constraints on the slider in the X / Y direction, the fixing point of the guide rail will coincide with the fastening point of the B-pillar trim, resulting in the B-pillar trim being unable to be fastened. Even if the fastening point of the B-pillar trim can be set at other positions, the fastening point will be exposed, reducing the user experience.
[0005] The utility model aims to solve the above technical problem, that is, to solve the problem that the B-pillar trim panel cannot be reliably fastened and the fastening point leaks when the guide rail is designed as a hard guide rail.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0039] To address the existing issues of poor X- and Y-direction constraint effects of rubber sealing strips on the glass and unstable dimensional performance, the inventors discovered that replacing the guide rail's rubber sealing strip design with a guide rail made of a hard material can provide strong X- and Y-direction constraint for the slider. However, this can lead to the guide rail's fixing point coinciding with the B-pillar trim's fastening point, preventing the B-pillar trim from being fastened. Alternatively, even if the B-pillar trim's fastening point can be relocated, the fastening point will be exposed, reducing the user experience.

Figure 5 、 Figure 6 FIG. 5 shows another embodiment of a B-pillar trim assembly in which an outer decorative panel, an intermediate bracket, a guide rail and a first seal are assembled. Figure 7 yes Figure 5 Schematic exploded view of the intermediate bracket and guide rails in Figure 7 The snap-fit structure is shown.
[0042] like Figure 1-Figure 3 See also Figure 4-Figure 7 As shown, in order to solve the problem that the B-pillar trim panel cannot be reliably fastened and the fastening point is exposed when the guide rail is designed as a hard guide rail. Figure 1 See also Figure 2-7 The present invention provides a B-pillar trim assembly 100, which is used to be installed in a vehicle. The vehicle includes a glass 1 and a slider 2 (such as Figure 3 、 Figure 6 As shown). Figure 2 See also Figure 3 、 Figure 5 and Figure 6The B-pillar trim assembly 100 generally includes an outer trim panel 10, an intermediate bracket 20, a guide rail 30, and a first seal 40. The outer trim panel 10, intermediate bracket 20, and guide rail 30 are arranged sequentially from the outside to the inside along the vehicle width. The first seal 40 is located on the inner side of the outer trim panel 10. The outer trim panel 10 is used to achieve a styling effect. The intermediate bracket 20 is connected to the outer trim panel 10 and is also fixedly connected to the guide rail 30. The intermediate bracket 20 provides component strength and a mounting point structure. The intermediate bracket 20 can be made of plastic or metal. The connection between the intermediate bracket 20 and the outer trim panel 10 can be adhesive, welding, or screwing. The fixed connection between the intermediate bracket 20 and the guide rail 30 can be screwing, clamping, adhesive, welding, or other fixed connection methods. The guide rail 30 is made of a hard material and provides motion guidance for the slider 2. It is also configured to provide X and Y constraints to the slider 2 to ensure dimensional stability. The hard material can be plastic or metal. The guide rail 30 is preferably made of metal. The first seal 40 is installed between the outer decorative panel 10 and the intermediate bracket 20 to provide a seal for the outer decorative panel 10 and the glass 1. The first seal 40 and the glass 1 interfere with each other. Figure 3 As shown, the X direction is defined along the length of the vehicle, and the Y direction is defined along the width of the vehicle.
[0043] When the above technical solution is adopted, the B-pillar trim panel of the present invention includes an outer trim panel 10, an intermediate bracket 20, a guide rail 30, and a first seal 40. The intermediate bracket 20 is connected to the outer trim panel 10, the guide rail 30 is fixedly connected to the intermediate bracket 20, and the first seal 40 is installed between the outer trim panel 10 and the intermediate bracket 20. The first seal 40 provides a seal for the outer trim panel 10 and the glass 1. Through the above structural design, the intermediate bracket 20 is connected to the outer trim panel 10 on one hand, and fixedly connected to the guide rail 30 on the other hand. This not only realizes the design of the B-pillar trim panel assembly 100 in which the outer trim panel 10 is integrated with the guide rail 30, avoiding the guide rail 30 from encroaching on the assembly space, but also saves the installation points of the outer trim panel 10 and the door inner panel, avoiding the problem of the outer trim panel 10 being unable to be fixed, avoiding the problem of the outer trim panel 10 being unable to be reliably fastened and the leakage of the fastening points, and at the same time avoiding the risk of water leakage and rust caused by the opening of the door inner panel. The guide rail 30 is made of hard material and provides strong constraints in the X and Y directions for the slider 2, so that the slider 2 is dimensionally stable, and a complete guide rail 30 is realized in the lifting area of the glass 1, ensuring the continuity of the lifting.
[0044] In addition, through the structural design of the outer decorative panel 10, the intermediate bracket 20, the guide rail 30 and the first seal 40, the B-pillar trim assembly 100 can be normally assembled in the factory, reducing the time and difficulty of online assembly.

[0046] As a possible implementation, Figure 2 As shown, the screw connection structure 50 may include: a nut 25 and a first fastener 5. The nut 25 is arranged in the intermediate bracket 20. The intermediate bracket 20 can be made by an injection molding process, and the nut 25 is pre-embedded in the mold and fixed in the intermediate bracket 20 by the injection molding process. The first fastener 5 can fasten the guide rail 30 and the intermediate bracket 20 together by engaging with the nut 25. The first fastener 5 can be a screw or a screw. In other embodiments, the intermediate bracket 20 can be made of metal, and the screw connection structure 50 can be that the nut 25 of the intermediate bracket 20 is replaced with an internal threaded hole, and the internal threaded hole matches the first fastener 5. The guide rail 30 and the intermediate bracket 20 can be fastened together by engaging with the first fastener 5 and the internal threaded hole.
[0047] As a possible implementation, Figure 5 See also Figure 7 The guide rail 30 and the intermediate bracket 20 are fixedly connected using a clamping structure 60 .
[0048] As a possible implementation, Figure 7 As shown, the latching structure 60 includes a slot 21, a latch tongue 22, a rib 23, and a latch hole 36. The slot 21, latch tongue 22, and rib 23 are all formed in the intermediate bracket 20. The ribs 23 are positioned on either side of the slot 21. Each rib 23 has a protrusion on the end away from the latch tongue 22, and a first limiting surface e1 is formed in the protrusion. The latch tongue 22 is formed above the slot 21, and a second limiting surface g is formed at the end of the latch tongue 22. The latch hole 36 is formed in the guide rail 30 for accommodating the latch tongue 22. The guide rail 30, the latch tongue 22, and the rib 23 cooperate to limit the displacement of the guide rail 30 in the X and Y directions. Specifically, the first limiting surface e1 and the second limiting surface g cooperate to control the X-direction displacement of the guide rail 30, and the sidewalls of each rib 23 cooperate with the sidewalls h of the latch tongue to control the Y-direction displacement of the guide rail 30. In other embodiments, the snap-fit structure 60 may also be other common snap-fit structures.
[0049] As a possible implementation, Figure 2-3 See also Figure 5-6 As shown, a first notch 11 is provided at one end of the outer decorative plate 10 away from the middle bracket 20, and the opening direction of the first notch 11 faces the direction away from the middle bracket 20.

The first notch 11 and the second seal 4 can also be snap-fitted. The first notch 11 designed in the outer trim panel 10 secures the outer trim panel 10 away from the guide rail 30.
[0050] As a possible implementation, Figure 3 See also Figure 6 As shown, the outer decorative panel 10 and the intermediate bracket 20 form a predetermined second notch 24 near the glass 1. The second notch 24 is used to engage the first seal 40. The first seal 40 is installed in the predetermined second notch 24 formed by the outer decorative panel 10 and the intermediate bracket 20, saving assembly time on the line.
[0051] As a possible embodiment, a semi-enclosed channel 35 is formed near the intermediate bracket 20 of the guide rail 30. The channel 35 is used to accommodate the slider 2 and provide motion guidance and strong constraints in the X and Y directions for the slider 2. Figure 2-3 See also Figure 5-6 As shown, the semi-enclosed channel 35 is formed by sequentially bending a first bend 31, a second bend 32, a third bend 33, and a fourth bend 34. The first bend 31 and the third bend 33 are parallel to the length of the outer decorative panel 10, while the second bend 32 and the fourth bend 34 are parallel to the width of the outer decorative panel 10. The first and third bends 31 and 33 provide strong constraints for the Y direction of the slider 2, while the second and fourth bends 32 and 34 provide strong constraints for the X direction of the slider 2. This design ensures that the guide rail 30 is continuous, thereby ensuring the consistency of the lifting and lowering of the glass 1.
