Description
A zero-face difference door sealing system Technical Field
[0001] The invention belongs to the technical field of vehicle door sealing systems, and in particular relates to a zero-face difference vehicle door sealing system. Background Art
[0002] Currently, traditional automotive door structures are primarily categorized by sheet metal manufacturing process into stamped door systems and rolled sash door systems. These systems are characterized by uneven alignment of the front and rear doors, the bodyside panels, and the sliding glass surface, resulting in a Y-axis step difference. This impacts the appearance consistency and increases the vehicle's drag coefficient during driving. Furthermore, the Y-axis position of the sliding glass during the raising and lowering process is controlled solely by the compressive load of the sealing strip lip, which fails to ensure stable positioning. The sealing force between the sealing strip lip and the sliding glass also fluctuates unevenly during the raising and lowering process, severely impacting sealing performance.
[0003] While the patented zero-face difference door system structure solves the problem of a "flush" side door appearance, it places extremely high demands on the manufacturing and assembly precision of the door system components, resulting in increased component costs. Furthermore, the black border between the sliding glass and the edge of the trim panel or guide rail is significantly wider than in traditional door systems, affecting visibility and appearance. The complex system structure after the glass is lowered also affects the overall aesthetics. Furthermore, the numerous limitations on the positioning of the sliding glass slider and sealing strip impose additional constraints on the assembly and integration of the system components, impacting installation efficiency.
[0004] Based on this, a zero-face difference door sealing system is proposed.
[0005] Summary of the Invention
[0006] The technical problem to be solved by the present invention is to provide a zero-face difference vehicle door sealing system in view of the deficiencies of the above-mentioned prior art, so as to solve the problems raised in the above-mentioned background technology.
[0007] To solve the above technical problems, the present invention adopts a technical solution: a zero-face difference vehicle door sealing system, comprising a first door sealing mechanism and a second door sealing mechanism, wherein the first door sealing mechanism is arranged between the A-pillar and the B-pillar of the vehicle body, and the second door sealing mechanism is arranged between the B-pillar and the C-pillar of the vehicle body, and the first door sealing mechanism and the second door sealing mechanism have the same structure;
[0008] Wherein, the first door sealing mechanism includes a first door glass run channel sealing strip, a movable glass assembly, a first door fixed corner window assembly, a first door B-pillar trim assembly, a first door B-pillar lower guide rail bracket and a lift assembly;
[0009] The movable glass assembly includes movable glass A-pillar limiting sliders attached to the edge of the A-pillar glass and movable glass B-pillar limiting sliders attached to the edge of the B-pillar glass;
[0010] A B-pillar guide rail sealing strip is installed on the inner side of the first door B-pillar trim assembly, and an A-pillar guide rail sealing strip is installed on the inner side of the first door fixed corner window assembly;
[0011] The movable glass A-pillar limiting slider is assembled in the X direction on the inner side of the A-pillar guide rail sealing strip, and is used to limit the position of the movable glass assembly A-pillar in the Y direction. The movable glass B-pillar limiting slider is assembled in the lower guide rail sealing strip on the inner side of the first door B-pillar lower guide rail bracket, and is then assembled to the movable glass B-pillar limiting slider in the Z direction, i.e., the vertical direction, through the B-pillar guide rail sealing strip assembled on the inner side of the first door B-pillar trim assembly, to limit the position of the movable glass assembly B-pillar in the Y and X directions.
[0012] The lifter assembly uses a single guide rail structure.
[0013] Furthermore, the A-pillar section lip of the guide channel sealing strip on the first door glass run channel sealing strip adopts a single lip structure, which shortens the width of the black edge area of the A-pillar area in the X direction and improves the driver's driving field of vision. When the movable glass assembly is lowered to the bottom, the A-pillar section lip of the guide channel sealing strip exposed in the field of vision is an integral single lip structure, which is convenient for wiping surface dust;
[0014] The B-pillar section lip of the guide groove sealing strip on the first door glass guide groove sealing strip adopts a single lip structure, which shortens the width of the black edge area of the B-pillar area in the X direction and improves the passenger field of vision. In addition, when the movable glass assembly is lowered to the bottom, the B-pillar section lip of the guide groove sealing strip exposed in the field of vision is an overall single lip structure, which is convenient for wiping surface dust.
[0015] Furthermore, the movable glass A-pillar limiting slider is made of PA66GF30% or PA66GF50%, wherein the Y-direction outward limiting feature of the first door movable glass A-pillar and the Y-direction inward limiting feature of the first door movable glass A-pillar limit the Y-direction structural characteristics, and the intermittent or staggered protrusions on the inner side of the A-pillar guide rail sealing strip play a low sliding resistance guiding role and can limit the Y-direction position of the A-pillar movable glass assembly, thereby achieving an appearance effect in which the movable glass A surface, i.e., the outer surface, is flush with the glass A surface, i.e., the outer surface, of the first door fixed corner window assembly.
[0016] Furthermore, the movable glass B-pillar limiting slider is made of PA66GF30% or PA66GF50%. The movable glass B-pillar limiting slider is positioned in the X direction by the first door movable glass B-pillar X-to-front side limiting feature. It plays a low sliding resistance guiding role on the inner side of the A-pillar guide rail sealing strip 3 of the movable glass assembly and can limit the Y-direction position of the A-pillar position of the movable glass assembly.
[0017] The Y-direction of the movable glass B-pillar limit slider is composed of discontinuous and staggered protrusions on the Y-direction inner limiting feature of the first door movable glass A-pillar and the Y-direction outer limiting feature of the first door movable glass A-pillar, which plays a low sliding resistance guiding role on the inner side of the B-pillar guide rail sealing strip of the movable glass assembly, and can limit the X-direction and Y-direction position of the B-pillar position of the movable glass assembly, thereby achieving an appearance effect that the A-side, i.e., the outer surface, of the movable glass is flush with the A-side, i.e., the outer surface, of the trim panel of the first door B-pillar trim panel assembly.
[0018] Furthermore, the first door fixed corner window assembly is composed of a front corner window glass, a first door corner window guide rail and an A-pillar guide rail sealing strip;
[0019] The A-pillar guide rail sealing strip is integrated into the first door fixed corner window assembly through post-assembly. The deformation groove structure of the A-pillar guide rail sealing strip can be deformed during installation, facilitating the installation and integration of the A-pillar guide rail sealing strip and improving the assembly efficiency of the system integration.
[0020] The injection-molded corner snap-in boss of the A-pillar guide rail sealing strip matches the snap-in boss of the first door corner window guide rail to limit the Z direction, ensuring that the A-pillar guide rail sealing strip does not move along the Z direction on the inner side of the first door corner window guide rail after the integrated first door fixed corner window assembly is assembled.
[0021] Furthermore, the first door B-pillar trim assembly uses a welding process to weld the exterior PC trim and the ABS trim into integration, and the B-pillar guide rail sealing strip is embedded in the welding mold cavity during the welding process and positioned after the PC trim and the ABS trim are pressed and welded together to form the first door B-pillar trim assembly or after the PC trim and the ABS trim are pressed and welded together, and then the B-pillar guide rail sealing strip is strung along the Z scheme of the PC trim into the inner side of the PC trim.
[0022] Furthermore, the upper end-sealed injection-molded portion of the B-pillar guide rail sealing strip has a B-pillar guide rail sealing strip injection-molded corner snap-fitting boss that is snap-fitted with the B-pillar trim panel slot notch to ensure Z-direction limit assembly supply, thereby improving the system installation efficiency. The B-pillar guide rail sealing strip is also provided with a B-pillar guide rail sealing strip deformation groove to facilitate better deformation installation during the installation process.
[0023] Furthermore, the first door B-pillar lower guide rail bracket is made of a PPTA30 material injection-molded base material part and screws and foam injection molding. The B-pillar guide rail sealing strip is pre-installed in the first door B-pillar lower guide rail bracket and supplied as the first door B-pillar lower guide rail bracket assembly, or the B-pillar guide rail sealing strip is strung into the inner side of the first door B-pillar lower guide rail bracket along the Z direction during system integration.
[0024] Furthermore, the upper part of the B-pillar lower guide rail sealing strip of the first door B-pillar lower guide rail bracket is clamped with the flange and the upper part of the lower guide rail bracket for clamping and limiting. The upper part of the first door B-pillar lower guide rail bracket is provided with a V-shaped guide groove and a positioning plug-in slot. The upper part of the first door B-pillar lower guide rail bracket is provided with a V-shaped guide groove to make the B-pillar guide rail sealing strip easier to guide and easy to install. The upper mounting groove of the lower guide rail bracket is plugged into the lower boss 5.1a of the B-pillar trim panel for auxiliary installation and limiting purposes.
[0025] Furthermore, the first door B-pillar guide rail sealing strip is a whole-section structure or a split structure. When the first door B-pillar guide rail sealing strip is a whole-section structure, it is installed to penetrate into the first door B-pillar lower guide rail bracket from the Z direction. When the first door B-pillar guide rail sealing strip is a split structure, it includes the first door B-pillar guide rail sealing strip and the lower guide rail sealing strip, which are divided into two components, serving as a split B-pillar guide rail sealing strip.
[0026] Compared with the prior art, the present invention has the following advantages:
[0027] 1. The present invention achieves a flush design with the A-surface of each door component and the A-surface of the movable glass, achieving zero surface difference. The flush design of the door side effectively reduces the drag coefficient during driving, thereby reducing the additional noise caused by the wind resistance of the shape and effectively improving the sealing quality inside the vehicle. Without special requirements for the door system components and sheet metal manufacturing, the lifter assembly can use a single guide rail, reducing costs. The overall system cost remains unchanged while achieving an improved appearance.
[0028] 2. When the window is lowered, the single lip structure of the guide channel sealing strip in the A / B / C section of this invention is simpler and easier to clean. Furthermore, the upper window frame guide channel sealing strip and the sliding glass still retain three sealing lips. This also reduces the step difference between the upper window frame bright trim strip and the sliding glass surface A, lowering the drag coefficient and, to a certain extent, improving wind noise and NVH performance. The integrated hemming process of the guide channel sealing strip and the fixed corner window assembly improves NVH and watertightness. This reduces the number of components to be assembled, shortens the installation process, reduces costs, and improves assembly efficiency. The integrated hemming process of the fixed corner window and the A / C pillar guide channel sealing strip also improves NVH and watertightness. The number of components to be assembled is reduced, and the installation process is shortened. The installation deformation groove of the guide rail sealing strip makes it easier to install the guide rail sealing strip into the A / C-pillar guide rail or the inside of the B-pillar trim. The "V"-shaped structure of the lower guide rail bracket and the plug-in matching structure with the B-pillar trim make it easier to assemble the integrated B-pillar trim assembly. The lower guide rail bracket can be pre-installed with the B-pillar guide rail sealing strip for segmented design or whole-segment design, which can match a variety of installation scenarios and assembly habits.
[0029] 3. The design of this invention optimizes the structure of the sliding glass upper slider, which can realize the structural features of a whole or segmented slider, and can adapt to various sliding glass slider structures. The guide rail sealing strip is U-shaped and manufactured by traditional extrusion technology. The slider structure adopts intermittent and staggered bumps. It is easy to paste and install.

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0043] As shown in Figures 1-15, the present invention provides a technical solution: a zero-face difference vehicle door sealing system, comprising a first door sealing mechanism and a second door sealing mechanism, wherein the first door sealing mechanism is disposed between the A-pillar and the B-pillar of the vehicle body, and the second door sealing mechanism is disposed between the B-pillar and the C-pillar of the vehicle body, and the first door sealing mechanism and the second door sealing mechanism have the same structure;
[0044] It can achieve a door side with no steps and zero surface difference, with a smoother appearance and a more overall mirror-like feel, beautiful shape, low cost, and no special requirements for glass thickness, as shown in Figure 1;
[0045] The first door sealing mechanism specifically includes a first door glass run channel sealing strip 1, a movable glass assembly 2, a first door fixed corner window assembly 3, a first door B-pillar trim assembly 4, a first door B-pillar lower guide rail bracket 5 and a lift assembly 6;
[0046] The A-pillar section lip 1.1 of the first door glass run channel sealing strip 1 adopts a single lip structure, which shortens the width of the black edge area of the A-pillar area in the X direction and improves the driver's driving field of vision. When the movable glass assembly 2 is lowered to the bottom, the A-pillar section lip 1.1 of the guide channel sealing strip exposed in the field of vision is an integral single lip structure, which is convenient for wiping surface dust;
[0047] The B-pillar section lip 1.2 of the guide groove sealing strip on the first door glass guide groove sealing strip 1 adopts a single lip structure, which shortens the width of the black edge area of the B-pillar area in the X direction and improves the passenger field of vision. In addition, when the movable glass assembly 2 is lowered to the bottom, the B-pillar section lip 1.2 of the guide groove sealing strip exposed in the field of vision is an integral single lip structure, which is convenient for wiping surface dust.
[0048] The movable glass assembly 2 includes a movable glass A-pillar limiting slider 2.1 attached to the edge of the A-pillar glass and a movable glass B-pillar limiting slider 2.2 attached to the edge of the B-pillar glass;
[0049] The movable glass A-pillar limiting slider 2.1 is made of PA66GF30% or PA66GF50%. The first door movable glass A-pillar Y-direction outward limiting feature 2.1a and the first door movable glass A-pillar Y-direction inward limiting feature 2.1b limit the Y-direction structural features. The intermittent or staggered protrusions on the inner side of the A-pillar guide rail sealing strip 3.1 serve as low-sliding resistance guides and can limit the Y-direction position of the A-pillar movable glass assembly 2, thereby achieving an appearance that the movable glass A-surface, i.e., the outer surface, is flush with the glass A-surface, i.e., the outer surface, of the first door fixed corner window assembly 3.
[0050] The movable glass B-pillar limiting slider 2.2 is made of PA66GF30% or PA66GF50%. The movable glass B-pillar limiting slider 2.2 is positioned in the X direction from the first door movable glass B-pillar X-direction to the front side limiting feature 2.2c on the inner side of the movable glass assembly 2 on the A-pillar guide rail sealing strip 3.1, which provides a low sliding resistance guide and can limit the position of the A-pillar and movable glass assembly 2 in the Y direction.
[0051] The movable glass B-pillar limit slider 2.2Y is composed of discontinuous and staggered protrusions on the Y-direction of the first door movable glass A-pillar Y-direction inner limiting feature 2.2b and the first door movable glass A-pillar Y-direction outer limiting feature 2.2a, which plays a low sliding resistance guiding role on the inner side of the B-pillar guide rail sealing strip 4.1 of the movable glass assembly 2, and can limit the X-direction and Y-direction position of the B-pillar position movable glass assembly 2, thereby achieving an appearance effect in which the A-side, i.e., outer surface of the movable glass, is flush with the A-side, i.e., outer surface of the trim panel of the first door B-pillar trim panel assembly 3.
[0052] The inner side of the first door B-pillar trim assembly 4 is equipped with a B-pillar guide rail sealing strip 4.1, and the inner side of the first door fixed corner window assembly 3 is equipped with an A-pillar guide rail sealing strip 3.1;
[0053] The first door fixed corner window assembly 3 is composed of a front corner window glass 3.1d, a first door corner window guide rail 3.2 and an A-pillar guide rail sealing strip 3.1;
[0054] The A-pillar guide rail sealing strip 3.1 is integrated into the first door fixed corner window assembly 3 through post-assembly. The deformation groove structural feature 3.1a of the A-pillar guide rail sealing strip can be deformed during installation, facilitating the installation and integration of the A-pillar guide rail sealing strip 3.1 and improving the assembly efficiency of the system integration.
[0055] The injection-molded corner snap-in boss 3.1c of the A-pillar guide rail sealing strip matches the snap-in boss 3.2 of the first door corner window guide rail to limit the Z direction, ensuring that after the integrated first door fixed corner window assembly 3 is assembled, the A-pillar guide rail sealing strip 3.1 does not move along the Z direction inside the first door corner window guide rail 3.2.
[0056] The movable glass A-pillar limiting slider 2.1 is assembled in the X direction on the inner side 3.1 of the A-pillar guide rail sealing strip, and is used to limit the position of the movable glass assembly 2 in the Y direction. The movable glass B-pillar limiting slider 2.2 is assembled in the lower guide rail sealing strip 5.1 on the inner side of the first door B-pillar lower guide rail bracket 5. It is then assembled to the movable glass B-pillar limiting slider 2.2 in the Z direction, i.e., the vertical direction, through the B-pillar guide rail sealing strip 4.1 assembled on the inner side of the first door B-pillar trim assembly 4, to limit the position of the movable glass assembly 2 in the Y and X directions.
[0057] The first door B-pillar trim assembly 4 uses a welding process to weld the exterior PC trim and the ABS trim into integration. The B-pillar guide rail sealing strip 4.1 is embedded in the welding mold cavity during the welding process and positioned after the PC trim and the ABS trim are pressed and welded together to form the first door B-pillar trim assembly 4 or after the PC trim and the ABS trim are pressed and welded together, and then the B-pillar guide rail sealing strip 4.1 is strung along the PC trim Z plan into the inner side of the PC trim.
[0058] The upper end sealing injection-molded part of the B-pillar guide rail sealing strip 4.1 has a B-pillar guide rail sealing strip injection-molded corner snap-fitting boss 4.1b which is snap-fitted with the B-pillar trim slot notch 4a to ensure Z-direction limit assembly supply, thereby improving the system installation efficiency. The B-pillar guide rail sealing strip 4.1 is also provided with a B-pillar guide rail sealing strip deformation groove 4.1a to facilitate better deformation installation during the installation process.
[0059] The first door B-pillar lower guide rail bracket 5 is made of a PPTA30 material injection-molded base material part and screws and foam injection molding. The B-pillar guide rail sealing strip 5.1 is pre-installed in the first door B-pillar lower guide rail bracket 5 and supplied as a first door B-pillar lower guide rail bracket assembly, or the B-pillar guide rail sealing strip 5.1 is strung into the inner side of the first door B-pillar lower guide rail bracket 5 along the Z direction during system integration.
[0060] The upper part of the B-pillar lower guide rail sealing strip of the first door B-pillar lower guide rail bracket 5 is engaged with the upper part of the B-pillar lower guide rail sealing strip 5.1b and the upper part of the lower guide rail bracket 5 for limiting the position. The upper part of the first door B-pillar lower guide rail bracket 5 is provided with a V-shaped guide groove and a positioning plug-in slot. The upper part of the first door B-pillar lower guide rail bracket 5 is provided with a V-shaped guide groove to make the B-pillar guide rail sealing strip 5.1 easier to guide and facilitate installation. The upper mounting groove 5a of the lower guide rail bracket is plugged into the lower boss 5.1a of the B-pillar trim panel for auxiliary installation and limiting purposes.
[0061] The first door B-pillar guide rail sealing strip 4.1 is a whole-section structure or a split structure. When the first door B-pillar guide rail sealing strip 4.1 is a whole-section structure, it is installed to penetrate into the first door B-pillar lower guide rail bracket 5 from the Z direction. When the first door B-pillar guide rail sealing strip 4.1 is a split structure, it includes the first door B-pillar guide rail sealing strip and the lower guide rail sealing strip, which are divided into two components as a split B-pillar guide rail sealing strip.
[0062] The lifter assembly 6 uses a single guide rail structure, and the X and Y positions of the movable glass during the lifting process are completely constrained by the guide rail sealing strip and the limit slider on the movable glass. This can effectively control the X and Y positions of the movable glass and effectively control the system cost.
[0063] The first door guide groove sealing strip or the rear door guide groove sealing strip of the present invention and the front fixed corner window glass assembly or the rear fixed corner window glass assembly can be formed by injection molding of an integral glass edge sealing. Taking the first door as an example, as shown in Figure 10: the front fixed corner window glass and the co-extruded A-pillar bent guide groove A-pillar section 1.11 and the A-pillar guide rail sealing strip are integrated into an assembly part. The cross-section of the A-pillar bent guide groove sealing strip adopts a solid or semi-solid hard steel strip or aluminum strip to ensure the rear curvature and strength of the bending.
[0064] The three system components—the triangular or quadrilateral window assembly, the guide rail seal, and the glass run channel seal—are integrated into a single part, reducing the number of parts and shortening installation time. This increases the system's integration rate. It also improves the sealing performance of the A-pillar guide rail and the glass run channel seal, reducing installation and matching, resulting in a cleaner appearance. A cross-section of a zero-face difference corner window with an integral injection-molded edge-sealed glass run channel seal is shown on the A-pillar and C-pillar.
[0065] During the specific implementation process, when it is an integral slider and a segmented guide rail sealing strip, the structure of the door system invention is as shown in Figure 2. The implementation example of the first door assembly and positioning principle is as follows: The first door system component: mainly composed of the first door guide groove sealing strip assembly 1, the first door movable glass assembly 2 is integrated into an assembly part by the movable glass A-pillar limiting slider 2.1 and the movable glass B-pillar limiting slider 2.2 through the structural glue gluing process; the first door fixed corner window assembly 3 is integrated into an assembly part by the A-pillar guide rail sealing strip installed on the inner side of the first door fixed corner window; the first door B-pillar trim assembly 4 is integrated into an assembly part by the B-pillar guide rail sealing strip 4.1 installed on the inner side of the first door B-pillar trim assembly; the first door B-pillar lower guide rail bracket 5 assembly is composed of the lower guide rail sealing strip 5.1 installed on the inner side of the first door B-pillar lower guide rail bracket as an assembly part.
[0066] The first door guide groove sealing strip assembly 1 is installed on the door sheet metal stop flange, and then the first door B-pillar lower guide rail bracket 5 assembly is installed on the door, and then the first door fixed corner window assembly 3 is installed, and then the first door movable glass assembly 2 is installed. The movable glass A-pillar limiting slider 2.1 is assembled on the inner side of the first door fixed corner window assembly 3 from the X direction, that is, the front-to-back direction, and is equipped with the inner side of the A-pillar guide rail sealing strip 3.1, which plays the role of limiting the A-pillar position of the first door movable glass assembly 2 in the Y direction, as shown in Figure 3.
[0067] The movable glass B limit slider 2.2 penetrates into the inner side 5.1 of the lower guide rail sealing strip from the Z direction, as shown in Figure 4, and then the first door B-pillar trim assembly 4 is installed. Then, the B-pillar guide rail sealing strip 4.1 assembled on the inner side of the first door B-pillar trim assembly 4 is assembled onto the movable glass B limit slider 2.2 from the Z direction, that is, the up and down direction, to limit the position of the B-pillar of the movable glass assembly 2 in the Y direction, that is, the left and right direction of the vehicle, and the X direction, that is, the front and back direction of the vehicle.
[0068] The second door system components, installation sequence, and system positioning limitations are the same as those of the first door.
[0069] The advantage of this integrated slider and segmented guide rail sealing strip implementation is that the B-pillar guide rail sealing strip 4.1 and the lower guide rail sealing strip 5.1 are segmented and integrated into the first door B-pillar trim assembly 4 and the first door B-pillar lower guide rail bracket 5 assembly. This reduces the difficulty of installing the system components. At the same time, the integrated slider attached to the A-pillar / B-pillar / C-pillar ensures smooth and low lifting resistance during the moving glass lifting process.
[0070] When the segmented slider and the integral guide rail sealing strip are used, the structure of the door system is shown in FIG11 ;
[0071] First door assembly and positioning principle case implementation description: First door system components: mainly composed of the first door guide channel sealing strip assembly 1; the first door sliding glass assembly 2 consists of the sliding glass A-pillar limit slider 2.1 and the sliding glass B-pillar limit slider 2.2, which are divided into two parts: the upper section of the 2.2 front / rear door sliding glass B-pillar limit slider and the lower section of the 2.2 front / rear door sliding glass B-pillar limit slider, respectively. They are integrated into an assembly part using a structural glue bonding process;
[0072] The first door fixed corner window assembly 3 is integrated into an assembly by installing the A-pillar guide rail sealing strip to the inner side of the first door fixed corner window;
[0073] The first door B-pillar trim assembly 4 is composed of a B-pillar guide rail sealing strip 4.1 installed on the inner side of the first door B-pillar trim assembly 4 and a first door B-pillar lower guide rail bracket assembly 5.
[0074] The first door guide groove sealing strip assembly 1 is installed on the door sheet metal stop flange, and then the first door B-pillar lower guide rail bracket assembly 5 is installed on the door, and then the first door fixed corner window assembly 3 is installed, and then the first door movable glass assembly 2 is installed. The movable glass A-pillar limit slider 2.1 is assembled on the inner side of the first door fixed corner window assembly 3 from the X direction, that is, the front-to-back direction, and the inner side of the A-pillar guide rail sealing strip 3.1 is assembled, which plays the role of limiting the A-pillar position of the first door movable glass assembly 2 in the Y direction, as shown in Figure 3.
[0075] The movable glass B limit slider 2.2 penetrates into the inner side of the lower guide rail sealing strip 5.1 from the Z direction, as shown in Figure 4, and then the first door B-pillar trim assembly 4 is installed. Then, a whole section of the B-pillar guide rail sealing strip 4.1 is assembled through the inner side of the first door B-pillar trim assembly 4, as shown in Figure 15. From the Z direction, that is, the up and down direction, it is assembled to the upper section of the 2.2 first door movable glass B-pillar limit slider and the lower section of the 2.2 first door movable glass B-pillar limit slider, which plays the role of limiting the position of the movable glass assembly 2 B-pillar in the Y direction, that is, the left and right direction of the vehicle, and the X direction, that is, the front and rear direction of the vehicle.
[0076] At the same time, the B-pillar guide rail sealing strip 4.1 moves the glass B limit slider 2.2 and then penetrates into the inner side of the first door B-pillar lower guide rail bracket assembly 5.
[0077] The second door system components, installation sequence, and system positioning limitations are the same as those of the first door.
[0078] The advantage of this segmented slider and integrated guide rail sealing strip implementation is that the entire B-pillar guide rail sealing strip 4.1 is integrated into the first door B-pillar trim assembly 4. Compared to the segmented slider and integrated guide rail sealing strip implementation, the installation process of the lower guide rail sealing strip 5.1 to the first door B-pillar lower guide rail bracket assembly 5 is eliminated. At the same time, the entire B-pillar guide rail sealing strip 4.1 is matched with the upper section of the first door sliding glass B-pillar limit slider 2.2 and the lower section of the first door sliding glass B-pillar limit slider 2.2 to ensure smooth and low lifting resistance during the moving glass lifting process.
[0079] The whole-section slider pasted on the movable glass 2 ensures the smoothness and lifting resistance of the movable glass during the lifting process.
