Description

Flush door structure with glass guide rail Technical Field

[0001] This invention relates to a flush door structure with glass guide rails, belonging to the field of automotive technology. Background Technology

[0002] Currently, the exterior surface of automobiles is gradually moving from an uneven structure to a completely smooth surface. There are already many cars on the market with basically flat door glass and B-pillar trim panels. However, different cars use different flush structures, which result in different assembly complexities and overall structure costs. Manufacturers need to improve processing and assembly efficiency and reduce processing costs while maintaining the original flush structure.

[0003] Existing patent 201911256801.3 uses a plastic rising profile as the main body for installation limitation, and the guide on the window is directly limited by the wire strand. Therefore, the wire strand is relatively long. When installing on the door, it needs to be inserted below the waistline of the door sheet metal, which is inconvenient and consumes a lot of materials. If the length of the wire strand is reduced, it is impossible to effectively slide and seal the lower part.

[0004] Furthermore, the existing door guide rails have a two-section structure. One section is installed from the top of the door, while the other requires drilling a hole in the existing door structure and then installing it below the waistline of the door sheet metal. This installation is inconvenient and inefficient. Moreover, because the upper and lower sections of the guide rail are disconnected, the alignment of the two sections is crucial, further impacting installation efficiency. If the two sections do not align, the glass slider will experience uneven sliding within the guide rails.

[0005] Summary of the Invention

[0006] The technical problem to be solved by this invention is: how to improve processing and assembly efficiency and reduce processing costs while ensuring that the doors are flush.

[0007] To solve the above-mentioned technical problems, the technical solution of the present invention is to provide a flush door structure with a glass guide rail, characterized in that it includes:

[0008] The door glass is installed on the side door of the vehicle, and opens and closes the window opening of the side door as the door glass is raised and lowered.

[0009] The glass slider has an opening on one side in the vehicle width direction and is located on the inner side of the door glass edge in the vehicle width direction, and extends along the vertical direction of the vehicle.

[0010] The glass guide rail is installed on the door sheet metal or the corner window assembly, extending below the waistline of the door sheet metal, and has a recess at one end to limit the glass slider in the width direction and the front and rear direction of the vehicle.

[0011] A sealing strip for the glass guide rail is provided in the recess of the glass guide rail and forms a recess along the recess of the glass guide rail, and is positioned on the outside of one end of the glass slider.

[0012] The glass guide channel sealing strip is installed on the door sheet metal and extends along the vertical direction of the vehicle. It abuts against the inner side of the door glass on one side in the width direction of the vehicle, and extends downward past the waistline of the door sheet metal.

[0013] Preferably, the glass guide rail is provided with a door trim panel.

[0014] Preferably, the outer surface of the door trim panel is flush with the outer surface of the door glass.

[0015] Preferably, the glass guide rail located on the A-pillar or C-pillar trim assembly is disposed on the door sheet metal; the glass guide rail located on the B-pillar trim assembly is disposed on the corner window assembly.

[0016] Preferably, the door glass and the glass slider form a door glass assembly, the glass guide rail and the glass guide rail sealing strip form a glass guide rail assembly, and the door glass assembly is provided with glass guide rail assemblies on both sides in the front-rear direction of the vehicle.

[0017] Preferably, the glass guide rail assembly has a C-shaped cross-section, with a recess in the vehicle width direction for accommodating the glass slider, limiting the glass slider in the vehicle's front-to-back and width directions, and extending in the vehicle's vertical direction.

[0018] Preferably, the glass guide rail sealing strip is disposed between the glass guide rail and the glass slider.

[0019] Preferably, glass sliders are provided on both sides of the door glass in the front-rear direction of the vehicle.

[0020] Preferably, the glass guide groove sealing strip includes a top section of the glass guide groove sealing strip, a first vertical section of the glass guide groove sealing strip, and a second vertical section of the glass guide groove sealing strip. The first vertical section of the glass guide groove sealing strip and the second vertical section of the glass guide groove sealing strip are respectively connected to the lower ends of the top section of the glass guide groove sealing strip. The first vertical section of the glass guide groove sealing strip and the second vertical section of the glass guide groove sealing strip extend past and below the waistline of the car door sheet metal.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] This invention reduces at least four plastic parts compared to existing products, saving on component costs. By installing metal glass guide rails, the limiting strength is improved, preventing the car door glass from swaying in all directions. The vertical section of the glass guide channel sealing strip is short, allowing the car door glass to slide up and down by only applying pressure to half to two-thirds of the glass edge length when the glass is fully lowered. Compared to existing technologies, this saves on material costs, and the shortened glass guide channel sealing strip is easier to install.

[0023] The glass guide rail in this invention extends from the top of the door sheet metal waistline to the bottom. During installation, the glass guide rail can be installed directly from the top of the door to below the door sheet metal waistline, allowing for a one-time installation and improving installation efficiency.
