A DOOR ASSEMBLY HAVING A REINFORCEMENT MEMBER FOR GLASS RUN OF A VEHICLE

FIELD OF DISCLOSURE

[0001] The present disclosure in general relates to the field of door panels of an automotive vehicles. In particular, the present disclosure relates to door assembly having a reinforcement member which is designed in such a manner that offers a continuous glass support throughout the sash span when the glass reached the top dead center (TDC) position to resolve the problems related to glass run sagging and waviness efficiently.

BACKGROUND
[0002] Automotive industry in India is one of the main pillars of the economy. With strong backward and forward linkages, it is a key driver of growth. In addition, automotive industry has always been known to be very competitive as far as its design and material usage are concerned. Therefore, the automotive industry is always facing greater market pressure to develop high quality products more quickly with different variants of a particular vehicle model in order to cater different segments of end users.
[0003] Nowadays, doors of the automotive vehicle are of major concern as the doors are expected to meet one of the toughest sets of requirements among interior car components. In general, doors serve as an interface between the interior of the car and the inner workings of the door, and between vehicle occupants and the door. They are expected to meet a variety of design specifications regarding safety, aesthetics, and functionality.
[0004] Generally, the doors are of two types, the panel type doors and the sash type doors. In panel type doors, the whole panel is made in a single die by forming. However, in sash type door, sash area is made by roll forming and lower panel area is made by forming. The sash and the lower panel area is then joined by welding. The present disclosure is related to the panel type doors. Referring FIGs. 1 and 2, a vehicle door assembly 100 as a whole includes an outer panel 102 and inner panel 104 adapted to be joined together to form the vehicle door. Further, the vehicle door assembly 100 has two sections, the upper section is called as sash area 106, and the lower section is called as lower door panel 108, wherein the sash area 106 is extending above the lower door panel 108.
[0005] In addition, the sash area 106 defines a space in which the glass 112 can move up to a top dead center (TDC) 114. In other words, TDC is the upper position of the glass where it stops. A reinforcement member is generally disposed in the inner panel 104, for providing a support to the glass 112 in the sash region.
[0006] In the existing conventional configuration of the door, there are problems related to part inaccuracy which leads to bulging of the glass run 116 in the local area.
[0007] In order to overcome the problem, different state of arts related to this field of technology has proposed several types of conventional configuration of the door.
[0008] Referring FIGs. 1 and 2A-2C, that illustrates the conventional configuration of the door along with detailed sectional view of sections ‘A-A’ (as shown in FIG. 2B) and ‘B-B’ (as shown in FIG. 2C), a door assembly (100) comprises two small reinforcements 202,204 that are welded on the door inner panel 104 to stop the glass 112 at top dead center (TDC) 114. The glass 112 in its TDC position 114 is only in contact with these two reinforcements 202,204. Due to the inaccuracies in placement of these two reinforcements 202, 204, the glass 112 contact surface of one of the reinforcements comes down. This pushes the glass run 116 down which in turn leads to the sagging problem of glass run 116 in the local area when viewed from outside.
[0009] Referring to FIG. 3A-3B, in another proposed conventional configuration of the door, a single reinforcement 300 having continuous glass support face along the sash span is welded on to the door inner panel 104 to stop the glass 112 at top dead center 114. The glass 112 at the TDC position 114 is in contact with the reinforcement 300 throughout the sash span. This reinforcement configuration 300 is such that it is welded into the inner panel 104 in the top near the hemming edge. Due to the L-shaped structure of the reinforcement, the reinforcement requires larger space in between the inner panel and the outer panel. This leads to increment in the overall section width of the inner panel 104 and the outer panel 102. Hence the overall cost of the reinforcement 300 and door increases.
[0010] Hence, there is an immense need to develop a reinforcement in the door assembly that overcomes the disadvantages associated with the existing reinforcements incorporated in the doors.

OBJECTS OF DISCLOSURE

[0011] Some of the objects of the present disclosure, which at least one embodiment herein satisfy, are listed herein below.
