Abstract
Description
Technical Field
[0001] The invention relates to a vehicle door structure, in particular to a vehicle door structure which can hide a vehicle door window frame above a waistline of the vehicle door. Background Art
[0002] At present, due to the existence of the door window frame, the traditional framed car door has a relatively high door stiffness above the waistline. The window frame above the waistline and the door sealing surface below the waistline have a smooth transition, and sealing strips can be arranged on the window frame, so the sealing performance is excellent. However, due to the exposed window frame, and the gap and step difference between the window frame and the glass, the appearance of the framed car door is not clean and smooth! Frameless car doors have a clean and smooth appearance, but because there is no window frame, the sealing stiffness above the waistline is only provided by the glass, resulting in poor sealing stiffness above the waistline of the door, and a sharp transition between the door glass and the door sealing surface below the waistline. At the same time, more sealing strips cannot be arranged above the waistline of frameless doors, so the sealing effect is poor!
[0003] With the development of the automobile industry, customers are paying more and more attention to the side shape of the car door and the wind noise performance of the whole vehicle. To meet the needs of customers, most vehicle manufacturers have adopted frameless doors or framed zero-step difference designs. Frameless doors have the following disadvantages: 1. The glass of frameless doors has no window frame support. At high speeds, due to the difference in air pressure inside and outside the car, the door glass is easy to stretch outward and the glass shakes on bumpy roads, which makes the door sound insulation performance worse than traditional doors; 2. There is a natural design gap between the frameless door and the body sealing strip, and the risk of door leakage is high; 3. The design of the glass lifting system and sealing system of frameless doors is complex, and the cost is much higher than that of traditional doors. Framed doors have the following disadvantages: 1. The window frame, window frame trim, window frame trim, and sealing strip are exposed, resulting in the door appearance not being clean and simple enough. 2. There are gaps and step differences between the window frame trim, window frame trim and glass, resulting in the door appearance not being smooth enough. This will cause more wind noise excitation.
[0004] Therefore, it is necessary to develop a door structure with hidden window frame that is low-cost, clean and smooth in appearance, and has excellent wind noise performance. To achieve a door structure with hidden window frame, how to achieve a structural integration of the advantages of framed door and frameless door structures is the key. Summary of the invention
[0005] The purpose of the present invention is to provide a window frame hidden door structure, which is a new matching structure used in the door pillar area, between the door glass, the door window frame, and the body trim panel. The door window frame is hidden inside the door glass, achieving the pillar appearance of a frameless door while having the sealing performance of a framed door.
[0006] To achieve the above object, the technical solution adopted by the present invention is: a window frame hidden door structure, used in the door pillar area, comprising:

[0014] Furthermore, the cross-section of the door glass lifting slider is in a "Z" shape.
[0015] Furthermore, the door glass lifting guide rail is fixed to the door window frame by a fastener.
[0016] Furthermore, the guide rail sealing strip is supported on the flange of the door glass lifting guide rail, so that the limiting surface of the guide rail sealing strip fits with the upper limiting surface of the door glass lifting slider, thereby limiting the door glass inwards and outwards.
[0017] Furthermore, the first lip edge and the second lip edge of the guide rail sealing strip are compressed and matched with the inner side surface of the door glass in the vehicle door, thereby providing sealing support for the door glass.
[0018] Furthermore, a gap of 1 to 3 mm is set between the limiting surface of the guide rail sealing strip and the door glass lifting slider in the front-rear direction of the vehicle to limit the movement of the door glass in the front-rear direction of the vehicle.
[0019] Furthermore, one side of the glass run channel sealing strip is supported on the flange of the door glass lifting guide rail, and the other side is supported on the flange of the door window frame. The limiting surface of the glass run channel sealing strip and the glass lifting slider are fitted in the front and rear directions of the vehicle to limit the movement of the door glass toward the edge of the door glass. The lip of the glass run channel sealing strip and the inner surface of the door glass are compressed and matched inside and outside the door to provide sealing support for the door glass.
[0020] Furthermore, the vehicle door window frame is covered with a vehicle door window frame interior decoration, and the opening edges on both sides of the vehicle door window frame interior decoration respectively cooperate with the guide rail sealing strip and the glass guide groove sealing strip to play a decorative role.
[0021] The beneficial effects of the present invention are:
[0022] The present invention adopts door glass, door window frame, door glass slider, door glass guide rail, guide rail sealing strip, glass guide groove sealing strip, body auxiliary sealing strip, body trim panel and other components to form a door structure with hidden window frame. It can connect and cooperate with the glass and the door window frame in the door B-pillar area, and hide the door window frame behind the glass, thereby achieving the appearance of a frameless door while maintaining the performance of a framed door.
[0023] Therefore, the window frame hidden door structure has a clean and simple appearance, excellent performance, and low cost, which is conducive to the large-scale promotion of the window frame hidden door structure. BRIEF DESCRIPTION OF THE DRAWINGS
