Description

Technical Field

[0001] This application relates to the field of vehicle component technology, and more specifically, to a side pillar connection assembly and a vehicle door. Background Technology

[0002] The development of new energy vehicles is rapid. Compared with traditional fuel vehicles, range is a crucial consideration for pure electric vehicles. Given fixed battery parameters, there are two paths to improve range: first, reducing vehicle weight; second, reducing the vehicle's drag coefficient. The main solution to reducing the drag coefficient is to minimize abrupt changes in the vehicle's exterior design. By reducing vortices generated during driving, the extra energy required for the pure electric vehicle to overcome wind resistance is reduced, thus increasing the driving range. A significant abrupt change in the design between the glass and the side pillars will generate greater wind resistance during vehicle operation, increasing energy consumption.

[0003] Therefore, a side pillar connection assembly and a door are needed to solve the above problems. Summary of the Invention

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0027] The vehicle door 100 includes a front door and a rear door. Taking the front door as an example, the glass on both sides of the front door has an A-pillar and a B-pillar, respectively. At least one of the A-pillars and the B-pillar is connected to the glass via a side pillar connection assembly. The A-pillar is connected to the glass 6 via the side pillar connection assembly, and the B-pillar is connected to the glass 6 via the side pillar connection assembly.

[0028] The A-pillar includes the front door main sealing strip 1, the front door secondary sealing strip 2, the front door inner panel 3, the trim panel fastening screws 4, the front door window frame interior panel 5, the A-pillar window frame sheet metal 10, and the side pillar connecting assembly. The front door inner panel 3 and the A-pillar window frame sheet metal 10 are fastened together. The front door window frame interior panel 5 covers the front door inner panel 3, providing a relatively harmonious appearance. The front door main sealing strip 1 and the front door secondary sealing strip 2 are respectively connected to the adjacent two sides of the front door window frame interior panel 5. The glass 6 is connected to the side pillar connecting assembly, which is connected to the A-pillar window frame sheet metal 10 by the trim panel fastening screws 4.

[0029] The B-pillar includes a front door main sealing strip 1, a front door secondary sealing strip 2, a front door inner panel 3, trim panel fastening screws 4, a front door window frame interior panel 5, a B-pillar window frame sheet metal 13, and a side pillar connecting assembly. The front door inner panel 3 and the B-pillar window frame sheet metal 13 are fastened together. The front door window frame interior panel 5 covers the front door inner panel 3. The front door main sealing strip 1 and the front door secondary sealing strip 2 are respectively connected to the adjacent two sides of the front door window frame interior panel 5. The glass 6 is connected to the side pillar connecting assembly. The side pillar connecting assembly is connected to the B-pillar window frame sheet metal 13 by the trim panel fastening screws 4.

[0030] Figure 1 This is a schematic diagram of a car door with a side pillar connection assembly used in a specific embodiment of this application. Figure 2 for Figure 1 The diagram shows a cross-section of column A. Figure 3 for Figure 2 A schematic diagram of the slider is shown. (As shown) Figures 1 to 3 As shown, the side column connection assembly includes a glass lifting guide rail, a flexible guide rail strip, and at least one sliding piece 7.

[0031] The glass lifting guide rail includes a support column and a first column, a second column and a third column connected to the support column in sequence at intervals. The first column and the second column are arranged opposite to each other and their extension directions are opposite to the extension direction of the third column. A connecting column extends from the first column and a decorative panel (i.e., A column decorative panel 9 or B column decorative panel 12) is provided on the third column.

[0032] The flexible guide rail covers the surface of the glass lifting guide rail facing the glass 6 and contacts one end of the glass 6. The flexible guide rail is set on the surface of the glass lifting guide rail facing the glass 6, such as covering the end face of the support column, the second column, the third column and the decorative panel in sequence from the first column, but not covering the decorative panel, and contacts the end of the glass 6 near the decorative panel.

[0033] At least one slider 7 is connected to a flexible guide rail outside the second column and is connected to the inner surface of the glass 6, so that the outer surface of the glass 6 is flush with the decorative panel.

[0034] When the side pillar connection assembly needs to cooperate with the A-pillar, the glass lifting guide rail provides guidance for the lifting of glass 6 above the side door waistline. The fourth pillar is connected to the A-pillar window frame sheet metal 10 by the trim fastening screw 4. The front door window frame interior panel 5 abuts against the first pillar. The flexible guide rail covers the side surface of the glass lifting guide rail facing glass 6, and one end abuts against glass 6. The slider 7 is connected to the flexible guide rail outside the second pillar. The slider 7 is connected to the inner surface of glass 6, so that the outer surface of glass 6 is flush with the trim panel outside the third pillar.

[0035] Using the aforementioned side pillar connection assembly, a flexible guide rail is installed on the glass lifting guide rail. The glass 6 is mounted on the flexible guide rail and the glass lifting guide rail via a slider 7. The slider 7 provides support and limit for the glass 6, enabling the glass 6 to achieve zero step difference with the trim panel during lifting or when relatively stationary. By reducing the step difference in the vehicle's exterior design, the eddies generated during driving are reduced, thereby reducing the extra energy required for the pure electric vehicle to overcome wind resistance and improving the driving range.

[0036] In one embodiment of this application, the support column extends vertically, the first column is located at the top of the support column and extends horizontally to the right, the second column is located in the middle of the support column and extends horizontally to the right, the third column is located at the bottom of the support column and extends horizontally to the left, and the fourth column is located above the first column and extends upward at an angle from the end near the support column, and the fourth column is provided with a screw hole.

[0037] In one embodiment of this application, the glass lifting guide rail adopts a two-color injection molding process, and the process requirements are met by staggered demolding. Compared with bonding or welding solutions, the unit price and mold cost are reduced to a certain extent.

[0038] In one embodiment of this application, the number of sliders 7 can be one or more. When there are multiple sliders 7, they can be spaced apart on the glass 6, and each slider 7 can be bonded to the inner surface of the glass 6. By providing two identical sliders 7 on the glass 6 at the A-pillar position, the weight of the sliders 7 is reduced.

[0039] In one embodiment of this application, the slider 7 includes, but is not limited to, an approximately U-shaped structure. The two relatively parallel surface contours of the U-shaped structure are fitted with the flexible guide rail with a gap. The outer surface of the U-shaped structure contacts the glass 6, thereby constraining the inward and outward positions of the slider 7 in the A-pillar area, thereby constraining the inward and outward positions of the glass 6 in the A-pillar area to achieve zero step difference between the glass 6 and the trim panel.

[0040] Optionally, the slider 7 includes a connecting plate and two mounting plates respectively connected to opposite ends of the connecting plate. The connecting plate and the two mounting plates form a groove. A slider is provided on one of the mounting plates. The groove is connected to a flexible guide rail outside the second column, and the slider is connected to the inner surface of the glass 6. The groove covers the outside of the flexible guide rail of the second column, and the inner surface of the mounting plate cooperates with the flexible guide rail, so that the slider 7 and the flexible guide rail achieve a clearance fit, and the slider is attached to the inner surface of the glass 6. In one embodiment of this application, the above-mentioned slider provides stable installation and good limiting and support effects.

[0041] In one embodiment of this application, the surface of the mounting plate facing the flexible guide rail has a gradient surface, and the height of this side surface of the mounting plate gradually increases and then gradually decreases, forming a smooth curved surface. The slider 7 has an adjustable contact area relative to the flexible guide rail, so that even with all dimensional deviations of the lifting system during the lifting process, a small contact area can still be maintained, thereby ensuring lifting speed and quality.

[0042] In one embodiment of this application, the inner surfaces of the two mounting plates of the slider 7 are symmetrical, and the shape of each curved surface can also be adjusted according to the installation requirements.

[0043] Optionally, the slider is positioned at one end of the mounting plate near the connecting plate and extends along the depth direction of the groove. By increasing the specific surface area of ​​the slider, the connection strength between the slider and the glass 6 is improved, thereby stably supporting and limiting the glass 6.

[0044] A flexible guide rail is disposed on the surface of the glass lifting guide rail facing the glass 6. Optionally, the flexible guide rail includes a first wrapping portion and a first support sealing portion extending from one end of the first wrapping portion. The first wrapping portion covers the second column and is laid below the second column at the end of the support column and the trim panel. The free end of the first support sealing portion abuts against the end of the glass 6. The inner surface of the first wrapping portion covers at least the second column, and typically covers most of the surface of the glass lifting guide rail facing the glass 6. The inner surface of the groove of the slider 7 mates with the outer surface of the first wrapping portion on the second column, jointly constraining the inner and outer positions of the glass 6 in the A-pillar area. The first support sealing portion contacts the end of the glass 6, cooperating to complete the lifting and sealing of the glass 6. The first support sealing portion can shield the trim panel surface after the glass 6 has descended. By using the above-mentioned flexible guide rail, the lifting and sealing of the glass 6 can be achieved, while ensuring that the glass 6 is flush with the trim panel, achieving zero step difference.

[0045] Optionally, the flexible guide rail also includes a first connecting portion, which extends from the other end of the first wrapping portion. The first connecting portion is sequentially laid on the supporting column and the first column above the second column, and its free end abuts against the interior panel of the door and window frame. An arc-shaped clearance structure is provided near the free end of the first connecting portion, and the interior panel 5 of the front door and window frame abuts against the first column, with the free end of the first connecting portion abutting against the interior panel 5 of the front door and window frame. Using the above-mentioned flexible guide rail, the structure is relatively compact for the A-pillar, achieving good guiding and sealing effects.

[0046] Figure 4 for Figure 1 A schematic diagram of the cross-section of column B is shown. Figure 4 As shown, the glass lifting guide rail also includes a fifth column and a glass sealing strip.

[0047] When the side pillar connecting assembly needs to cooperate with the B-pillar, the glass lifting guide rail may optionally include a fifth pillar. The fifth pillar is set on the first pillar and has a glass sealing strip. The glass sealing strip interferes with the glass 6, and the side of the glass sealing strip contacts the sliding plate 7. The glass lifting guide rail provides guidance for the lifting of the glass 6 above the side door waistline. The fourth pillar is connected to the B-pillar window frame sheet metal 13 by trim panel fastening screws 4. The front door window frame interior panel 5 abuts against the first pillar. The flexible guide rail covers the side surface of the glass lifting guide rail facing the glass 6, and one end abuts against the glass 6. The sliding plate 7 (the same structure of sliding plate can be used for the A-pillar and B-pillar, or selected according to specific circumstances) is connected to the flexible guide rail outside the second pillar. The sliding plate 7 is connected to the inner surface of the glass 6, so that the outer surface of the glass 6 is flush with the trim panel outside the third pillar. The fifth pillar is equipped with a glass sealing strip, and the free end of the glass sealing strip interferes with the glass 6, thereby improving the sealing performance of the glass 6.

[0048] Using the aforementioned side column connection assembly, a flexible guide rail is installed on the glass lifting guide rail. The glass 6 is installed on the flexible guide rail and the glass lifting guide rail via a sliding piece 7. The sliding piece 7 provides support and limit function for the glass 6, so that the glass 6 can achieve zero step difference with the trim panel during the lifting process or when relatively stationary. At the same time, a glass sealing strip is installed on the glass lifting guide rail, which can provide the sealing of the glass 6.

[0049] In one embodiment of this application, the glass sealing strip includes a sealing groove and a sealing arc. The sealing groove covers the fifth column, and one sidewall of the sealing groove abuts against the sliding piece 7. Multiple sealing edges are provided on the other sidewall of the sealing groove, distributed on opposite sides of the sidewall and staggered along the sidewall. One sealing edge abuts against the fifth column, and the other sealing edge abuts against the front door window frame interior panel 5 or the first column. The sealing arc is located opposite the sealing groove and can abut against the glass 6. The sealing arc has deformation space, providing an elastic seal for the glass 6. The glass sealing strip is interference-fitted with the inner surface of the glass 6 to seal the glass 6, and its overlap with the front door window frame interior panel 5 ensures aesthetic harmony.

[0050] See also Figure 4 A flexible guide rail is disposed on the surface of the glass lifting guide rail facing the glass 6. Optionally, the flexible guide rail includes a second wrapping portion and a second support sealing portion and a second connecting portion extending from opposite ends of the second wrapping portion. The second wrapping portion covers the second column and is laid below the second column at the ends of the support column and the trim panel. The free end of the second support sealing portion abuts against the end of the glass 6; the second support sealing portion can cover the surface of the trim panel after the glass 6 is lowered. The second connecting portion is sequentially laid on the support column and at least partially on the first column above the second column, and the free end of the second connecting portion has a gap with the fifth column. The inner surface of the second wrapping portion covers at least the second column, and usually covers most of the surface of the glass lifting guide rail facing the glass 6. The inner surface of the groove of the slider 7 cooperates with the outer surface of the second wrapping portion on the second column to jointly constrain the inner and outer positions of the glass 6 in the B-pillar area. The second support sealing portion contacts the end of the glass 6 to cooperate in completing the lifting and sealing of the glass 6. The second connecting part is sequentially laid on the supporting column and at least part of the first column above the second column, and is a certain distance away from the fifth column. The interior trim panel 5 of the front door window frame abuts against the first column, and the glass sealing strip abuts against the interior trim panel 5 of the front door window frame through the sealing edge. Using the above-mentioned flexible guide rail strip, the structure for the B-pillar is relatively ingenious, achieving a good guiding and sealing effect. It can realize the lifting and sealing of the glass 6, while ensuring that the glass 6 is flush with the trim panel, achieving zero step difference.

[0051] See also Figure 4Optionally, the slider 7 also includes a protrusion disposed on the surface of the connecting plate opposite to the groove and capable of contacting the glass sealing strip. Through the clearance fit between the curved surfaces of the two relatively parallel mounting plates of the slider 7 and the flexible guide rail, the slider 7 inside the B-pillar is constrained in the inward and outward positions, thereby constraining the inward and outward positions of the glass 6 in the B-pillar region; through the cooperation of the protrusion on the connecting plate with the glass sealing strip, the slider 7 inside the B-pillar is constrained in the forward and backward positions, thereby constraining the forward and backward positions of the glass 6 in the B-pillar region. Using the above-mentioned slider 7 can assist in achieving multi-directional fixation of the glass 6 and improve stability.

The flexible guide rail covers the side surface of the glass lifting guide rail facing glass 6, and one end abuts against glass 6. The slider 7 is connected to the flexible guide rail outside the second pillar. The slider of the slider 7 is connected to the inner surface of glass 6, so that the outer surface of glass 6 is flush with the trim panel outside the third pillar, which is used to limit the inward and outward position of glass 6 in the A-pillar area.

[0054] When the side pillar connecting assembly needs to cooperate with the B-pillar, the glass lifting guide rail provides guidance for the lifting of glass 6 above the side door waistline. The fourth pillar is connected to the B-pillar window frame sheet metal 13 by the trim panel fastening screw 4. The front door window frame interior panel 5 abuts against the first pillar. The flexible guide rail covers the side surface of the glass lifting guide rail facing glass 6, and one end abuts against glass 6. A glass sealing strip is installed on the fifth pillar, and the free end of the glass sealing strip interferes with glass 6. The protrusion of the slider 7 abuts against the glass sealing strip to limit the front-rear position of glass 6 in the B-pillar area. The slider 7 is connected to the flexible guide rail outside the second pillar. The slider of the slider 7 is connected to the inner surface of glass 6, so that the outer surface of glass 6 is flush with the trim panel outside the third pillar to limit the inward and outward position of glass 6 in the B-pillar area.
