A doors and window frame assembly, door assembly and cars

Abstract

The present invention involves the field of automobile manufacturing technology. Specific disclosure of a doors and windows frame assembly, door assembly and cars. The door and window frame assembly of the car includes the doors and windows and window frames.One -piece window frame, window frame rear frame, rearview mirror fixing board, front and lower guide rails, front and lower guide rail brackets, and front window sills to enhance boards.Between; strengthen board components, strengthen plate components using aluminum alloy material extrusion molding, strengthen the plate component and the door and window frame can be removed, and jointly cooperate to form a installation structure used to install the door density sealing and glass guide slots.The integrated structure of the door and window frame reduces the number of parts and components for easy assembly; the door and window frames are made of magnesium alloy materials, high degree of lightweight, and simple forming process; enhanced board components are squeezed out of aluminum alloy materials, and the molding process is simple, And the disassembly connection method is easy to assemble.

Description

Technical field [0001] The present invention involves the field of automobile manufacturing technology, especially a doors and windows, door assembly, and cars. Background technique [0002] At present, the common models on the market are generally window frame door assembly, that is, the door window frame and the inner panel of the door are the separation structure, and the two need to be welded together.The advantage of this window frame is that the generalization rate is high, and different models can share the same section structure.However, with the continuous improvement of the lightweight requirements of the car, the disadvantages of this window frame are also increasingly prominent, that is, the lightweighting difficulty is greater. Reason one: if the window frame material is directly changed to aluminum alloy, the roller formation is difficult; the reason for the two reasons 2: The door sealing of the door and the guide slot on the window frame is generally common in mul...

AI Technical Summary

Problems solved by technology

However, with the continuous improvement of automobile lightweight requirements, the disadvantages of this kind of window frame are becoming more and more prominent, that is, it is more difficult to reduce the weight. Reason 1: If the material of the window frame is directly changed to aluminum alloy, it will be difficult to roll forming; Reason 2 : The section of the door sealing strip and guide groove snapped on the window frame is generally common to multiple models, so the window frame structure matching the sealing strip and guide groove cannot be changed, which brings many restrictions to the optimization of the window frame section

[0003] like figure 1 As shown, the current traditional door and window frame assembly mainly includes window frame upper frame 1', window frame rear frame 2', rearview mirror fixing plate 3', front lower rail 4', front lower rail bracket 5' and other components. The components are connected by spot welding and oxygen dioxide welding, so there are defects such as many parts and poor precision, which will affect the function and performance of the door assembly. Less, not conducive to weight reduction of the door
