[0043] There is a step difference between the traditional car structure and the B-pillar trim structure, which leads to poor appearance perception. Due to the step difference, there is a large wind resistance when the vehicle is driving, and wind noise is generated, which leads to customer dissatisfaction. Although improvements have been made in existing vehicles, the noise, vibration and harshness (NVH) performance is poor. Therefore, improving NVH performance on the basis of flush door components is a technical problem that needs to be solved urgently.

[0044] In order to solve the above technical problems, refer to Figures 1 to 3 As shown, the present application provides a vehicle door assembly, including a glass 10, a trim panel structure 20 and a sliding assembly 30, wherein the outer surface of the trim panel structure 20 is flush with the outer surface of the glass 10, and a first gap 35 is provided between the trim panel and the glass 10; the sliding assembly 30 includes a slide rail 31, a slider 32 and a first seal 33, the slide rail 31 is connected to the trim panel structure 20, the slide rail 31 forms a slide groove 311, the slider 32 is connected to the glass 10 and slides with the slide groove 311 to realize the lifting of the glass 10, the first seal 33 and the slide rail 31 are an integral structure, the first seal 33 is arranged at the first gap 35, the side wall of the slide groove 311 is provided with a first wear-resistant layer 34, and the thickness of the first wear-resistant layer 34 is between 200um and 250um. Therefore, the outer surface of the trim structure 20 is flush with the outer surface of the glass 10, which can reduce the step difference between the glass 10 and the trim structure 20, reduce the wind resistance and wind noise when the vehicle is driving, and the slide rail 31 and the slider 32 can form a sealing structure while realizing the lifting of the glass 10. The first wear-resistant layer 34 is arranged on the side wall of the slide groove 311 to reduce the friction coefficient of the slide rail 31 and the slider 32, and a better sealing effect can be achieved through the first wear-resistant layer 34 while achieving a good sliding effect. At the same time, the first seal 33 arranged in the first interval 35 can further achieve a better sealing effect on the gap between the glass 10 and the trim structure 20, thereby improving the NVH performance of the whole vehicle.

[0045] In some embodiments, the slide rail 31 and the first seal 33 are both rubber parts, and the slide rail 31 and the first seal 33 are integrally formed by an extrusion process. The trim structure 20 and the glass 10 are located on the surface of the vehicle body, and the first interval 35 is arranged in the direction from the front of the vehicle to the rear of the vehicle. The width of the first seal 33 is slightly larger than the first interval 35, and it needs to be squeezed when installed in the first interval 35, so as to have a better sealing effect. The first seal 33 includes wavy patterns on both sides, and the wavy patterns on both sides are respectively pressed against the trim structure 20 and the glass 10. The extruded seal can increase the contact area through the wavy patterns, thereby improving the sealing performance among the first seal 33, the trim structure 20, and the glass 10.

[0046] In some embodiments, the first wear-resistant layer 34, the slide rail 31, and the first seal 33 are integrally formed by extrusion. The first wear-resistant layer 34 can also be formed on the side of the slide rail 31 away from the slide groove 311 to increase the wear resistance of this surface and the overall life of the slide rail 31.

[0047] In some embodiments, the glass 10 is double-layer glass 10 with good NVH performance. The size, model and thickness of the glass 10 are selected according to actual conditions and are not specifically limited here.

[0048] In some embodiments, reference Figure 2 As shown, the slide rail 31 includes a first hardened portion 312 and a first softened portion 313. The first hardened portion 312 forms a slide groove 311. The notch of the slide groove 311 faces one side of the glass 10. The slider 32 extends into the slide groove 311 through the notch. The first softened portion 313 is arranged on the side of the first hardened portion 312 away from the first seal 33. Since the slide rail 31 is made of rubber and has good flexibility, the slide groove 311 can be formed by bending the slide rail 31. The slider 32 is extended into the slide groove 311 through the notch to form a sliding fit. The first softened portion 313 can extend to one side of the glass 10 and then abut against other structures, further improving the sealing performance. Specifically, the first seal 33, the first hardened portion 312, and the first softened portion 313 are all made of EPDM rubber. The Shore hardness of the first hardened portion 312 is between 62 and 68 degrees. The density of the first seal 33 and the first softened portion 313 is between 0.55 g / mm 3 Up to 0.65g / mm 3 The hardness of the first hardened portion 312 is greater than that of the first softened portion 313. The first hardened portion 312 is made of EPDM rubber with a Shore hardness of 62 to 68 degrees, which has relatively balanced plasticity and rigidity and can form a relatively flat slide groove 311 to make the slider 32 move more smoothly. The first seal 33 and the first softened portion 313 are made of a density of 0.55g / mm 3 Up to 0.65g / mm 3 The EPDM rubber has lower hardness and better flexibility. When it is arranged at the first interval 35 and other structures with gaps, it can have a tighter fit with the decorative panel structure 20, glass 10 and other structures to achieve a good sealing effect.

[0049] In some embodiments, reference Figure 3As shown, the slider 32 includes a sliding portion 321 and a connecting portion 322 which are arranged as an integral structure. The sliding portion 321 is arranged in the slide groove 311, and the connecting portion 322 is connected to the glass 10. The surface of the connecting portion 322 facing the glass 10 forms a texture 323, and a first adhesive body 324 is arranged between the glass 10 and the texture 323. The sliding portion 321 is used to cooperate with the slide groove 311, and the connecting portion 322 is used to connect the glass 10. By arranging the texture 323 on the connecting portion 322, the contact area between the connecting portion 322 and the first adhesive body 324 can be increased, so that the connecting portion 322 and the glass 10 have better connection stability. The material of the first adhesive body 324 is glass glue, double-sided tape, etc. Specifically, the slider 32 is made of polypropylene and glass fiber, and the proportion of polypropylene and glass fiber is between 45% and 55%. The first viscous body 324 is made of glass glue and double-sided adhesive. If the proportion of polypropylene is about 45%, the proportion of glass fiber is about 55%. On the contrary, if the proportion of polypropylene is about 55%, the proportion of glass fiber is about 45%. The slider 32 can be formed by mixing polypropylene and glass fiber to form a molten body for injection molding. The proportion of polypropylene and glass fiber and the material of the first viscous body 324 are selected according to actual needs. The mixed material of polypropylene and glass fiber can improve heat resistance, reduce shrinkage, improve rigidity, etc., thereby improving the service life of the slider 32.

The second spacer 51 can provide a sliding space between the glass 10 and the door panel structure 40. Based on such a design, a second seal 50 needs to be arranged to seal the spacer to improve the NVH performance of the vehicle. Specifically, the second hardening portion 52 and the second softening portion 53 are both made of EPDM rubber. The Shore hardness of the second hardening portion 52 is between 62 and 68 degrees, and the density of the second softening portion 53 is between 0.55 g / mm 3 Up to 0.65g / mm 3The hardness of the second hardened portion 52 is greater than that of the second softened portion 53. The second hardened portion 52 is made of EPDM rubber with a Shore hardness of 62 to 68 degrees, which has good structural strength and can have better connection stability with the door inner panel 41. The second softened portion 53 is made of a 0.55g / mm 3 Up to 0.65g / mm 3 The EPDM rubber in between has better flexibility and can form a good abutment fit with the glass 10, thereby having a better sealing effect.

The material of the second wear-resistant layer 55 is lipid, and the thickness of the second wear-resistant layer 55 is between 180um and 250um. The thickness of the second wear-resistant layer 55 is less than the thickness of the first wear-resistant layer 34. The second wear-resistant layer 55 is arranged on the second softening portion 53 to reduce the friction coefficient between the glass 10 and the second softening portion 53, and can achieve a better sealing effect through the second wear-resistant layer 55 while achieving a good sliding effect. It can also increase the service life of the second seal 50.

The connector 22 is an engineering plastic, and the first buckle 221 and the second buckle 222 are formed close to one side of the door panel structure 40 and close to the first seal 33, respectively, so as to form a connection relationship with the door panel structure 40 and the first seal 33.

[0053] Further, see Figure 6 As shown, on one side of the door panel structure 40, the door inner panel 41 and the door outer panel 42 are clamped in the first clamp 221; the first seal 33 includes a first hardened portion 312, and the first hardened portion 312 forms a first clamping portion 3121 on the side of the first hardened portion 312 facing the trim structure 20, and the second clamp 222 is clamped in the first clamping portion 3121.
