And the reinforcement fagging being connected with back external door panel.
Further, along back door thickness direction, the reinforcement fagging and inner panel reinforcing plate, door lock installation portion
And the line of back external door panel tie point is triangular in shape.
Further, the reinforcement fagging is in Z-shaped, and the two ends of the reinforcement fagging add with inner panel respectively
Strong plate is connected with door lock installation portion, described to strengthen fagging close to the kink and back door of inner panel reinforcing plate
Outside plate is connected.
Further, it is provided with lightening hole on the reinforcement fagging.
Further, along the length direction of the inner panel reinforcing plate, in the both sides of inner panel reinforcing plate are formed with
Plate reinforcing plate flange.
Further, it is provided with lightening hole in the inner panel reinforcing plate.
Further, the door lock installation portion is the box-like of both ends open, and is formed with one end opening
Door lock installation portion flange, the reinforcement fagging is connected on door lock installation portion flange.
Further, another openend, the door lock peace are pointed to by the openend with door lock installation portion flange
The section in dress portion is gradually small.
Relative to prior art, the present invention has the advantage that:
(1) automobile back door structure of the present invention, back door can be increased by the setting of inner panel reinforcing plate
Lateral stiffness, the local stiffness of back door lock mount point can be increased by the setting of door lock installation portion, and
Coupling stiffness between each component of back door can be increased by the setting for strengthening fagging, thus after it may be such that automobile
Tailgate has preferable rigidity, to ensure the using effect of back door.
(2) it is in three to strengthen fagging with the line of inner panel reinforcing plate, door lock installation portion and back external door panel tie point
Stability feature that is angular, having using triangular structure, the structure for improving component at each tie point is firm
Degree.
(3) strengthen fagging and be set to Z-shaped, its simple structure is easy to design, and can be single piece
Shaping, is easy to technique to process.
(4) setting lightening hole can ensure the integrally-built lightweight of back door, and setting flange can improve inner panel and add
The structural strength of strong plate.
(5) door lock installation portion is box-like, it is ensured that door lock installation portion has structural strength higher, and setting is turned over
Side then can further improve the coupling stiffness that door lock installation portion is connected with each component.
(6) gradually I is easy to its arrangement on back door in door lock installation portion section.
Another object of the present invention is to propose a kind of body of a motor car, the body of a motor car includes as described above
Automobile back door structure.
This body of a motor car and automobile back door structure had the advantage that relative to prior art it is identical, herein
Repeat no more.
