The lifting track and the limiting of the lifter are limited by a first double-material injection molding slide block 2a and a second double-material injection molding slide block 2b on the movable glass 2 assembly, a second guide rail sealing strip 3a and a decorative plate 3 on the decorative plate assembly and a first guide rail sealing strip 4a connected with a zero-surface difference angle window, so that the X-direction track and the Y-direction track are limited, and the matching of the flatness of the outer side surface and the appearance effect of zero surface difference are realized.
According to the zero-surface-difference vehicle door system, the Y-direction position of the movable glass assembly is limited by the fact that the first double-material injection molding slide block 2a on the movable glass assembly 2 and the first guide rail sealing strip 4a on the inner side of the guide rail of the zero-surface-difference angle window are matched with the limiting structure. Meanwhile, a second guide rail sealing strip 3a on the inner side of the B column decorative plate is matched with a second double-material injection molding sliding block 2B on the movable glass assembly 2 to form a limiting structure, so that the Y-direction and X-direction positions of the movable glass assembly are limited. The sealing lip of the channel sealing strip 1 is hidden to the Y inner side of the moving glass 20 and the plaque 3, so that the design of zero surface difference between the A surface of the moving glass and the A surface of the plaque is realized. According to the zero-surface-difference vehicle door system, only the Y-direction position is limited between the first guide rail sealing strip 4a and the first double-material injection molding sliding block 2a on the inner side of the corner window, and the influence of tolerance stack of machining and assembling of all components is effectively absorbed. The design concept of the zero-plane-difference vehicle door system only needs the lifter 6 to provide glass lifting Z-direction boosting force, and the requirements of flatness and alignment degree of matching of the X-direction and the Y-direction of the moving glass with side components such as a decorative plate and a corner window in the lifting process can be met.
According to the zero-surface-difference vehicle door system, the Y-direction positioning of the movable glass in the lifting process is realized by respectively matching and positioning a first double-material injection molding slide block 2a and a second double-material injection molding slide block 2B on the movable glass with a zero-surface-difference corner window and a B-pillar decorative plate 3 in the Y-direction; the X-direction positioning of the movable glass in the lifting process is realized by matching and positioning a second double-material injection molding slide block 2B on the movable glass and a B column decorative plate assembly in the X-direction. Different from the X-direction and Y-direction limiting structures of the traditional window lifter. Compared with the traditional window winder, the zero-surface-difference vehicle door system has the advantages that the design concept is more reliable in positioning in the X direction and the Y direction, and the positions of the moving glass in the X direction and the Y direction are more stable in the lifting process. The front door B column lower guide rail bracket 5, the rear door B column lower guide rail bracket 5B and the rear door C column lower guide rail bracket 5C are used as glass and fall to the bottom lower dead center to play the role of limiting in the X direction and the Y direction, so that the shaking amount of the glass can be effectively reduced when the door is closed.
The zero-surface-difference vehicle door system solves the problem of the difference between the traditional vehicle punching type and rolling type window frame vehicle door structures and various assembly components on the side surface of a vehicle body and the molding Y-direction step surface of the moving glass A surface, and improves the appearance effect. Effectual reduction windage coefficient reduces the windage noise, ensures the NVH performance, has strengthened the removal glass lift in-process Y to with X to spacing ensure the positional stability who removes the glass lift in-process, ensure the sealing strip lip edge and glass's even sealing force, ensure good leakproofness.
Compared with the structure of the conventional frameless vehicle door system, the zero-surface-difference vehicle door system has no special matching modeling requirements on the thicknesses of a sheet metal, a window lifter assembly and moving glass, and the like, and realizes the modeling effects of flushing and zero-surface difference of components on the side surface of a vehicle body on the premise of ensuring that the manufacturing and assembling process, NVH (noise, vibration and harshness) performance and the like of the conventional integrally-stamped vehicle door sheet metal are not influenced; and the cost of the vehicle door system component is effectively controlled.
According to the height of the moving glass, a segmented double-material injection molding slide block can be adopted. The guide rail bar and the guide groove sealing strip are split, the two sections form a flexible guide rail section which is better matched with the curvature of the surface of the glass, and the double-material injection molding sliding block is convenient to bond; the double-material injection molding sliding block can effectively reduce system resistance, and has strong deviation inclusion and good tolerance on system components; the guide rail sealing strip is designed in a U shape, is easy to install and is manufactured by adopting the traditional processing method.
In conclusion, the zero-surface-difference vehicle door system can realize the modeling of the side surface of the vehicle door without steps and zero-surface difference, has smoother appearance, more integral mirror surface feeling, attractive modeling and low cost, and has no special requirement on the thickness of glass.
