Description
Technical field
The present invention relates to the components of automobile, more specifically to a kind of automobile back door inner panel.
Background technique
The back door main body of two-box automobile or SUV generally use metal plate punching molding, have weight big, and moulding, which is restricted, etc. lacks
Point.As energy-saving and emission-reduction requirement is increasingly stringenter, plastics tailgate is because of integrated level height, and weight loss effect is obvious, moulding freedom degree height etc.
Advantage is got more and more attention, and full injection molded back door (interior plate material is PP+GF, and outer plate material is PP) is especially concerned.But
It is the PP+GF material that full injection molding backdoor inner plate uses, whether relative to metal plate or SMC, modulus will be much lower, it is necessary to
It just can guarantee the performances such as tailgate rigidity, intensity by Optimal Structure Designing.Therefore, plastics tailgate needs to give full play to PP+GF material
The high feature of material molding freedom degree, optimizes inner plate structure of backdoor, while meeting the performances such as tailgate rigidity and light weight
Change loss of weight target.
Summary of the invention
The object of the present invention is to provide a kind of automobile back door inner panels, can effectively promote the overall stiffness of plastics back door
Under the premise of, while realizing lightweight.
Automobile back door inner panel of the present invention, including backdoor inner plate ontology offer gear on the top of backdoor inner plate ontology
Wind glass transmission region apertures, the region positioned at windshield transmission region hole two sides is the D column in trench structure, in backdoor inner plate
The middle and lower part of ontology offers taillight mounting hole and rear door lock mounting hole, is provided with facade structures on D column, the facade structures
Left and right side and inner side edge are connect with the left and right cell wall of D column groove structure and slot bottom respectively, in the outer side edges of facade structures
It is provided with flange, the both ends of flange are connect with the left and right cell wall of D column respectively.
Further, also there is groove structure at the lower left corner and the lower right corner of backdoor inner plate ontology, in the groove structure
Be also equipped with facade structures, the left and right side of the facade structures and inner side edge respectively with the left and right cell wall and slot of D column trench structure
Bottom connection, is provided with flange, the both ends of flange are connect with the left and right cell wall of D column respectively in the outer side edges of facade structures.
Further, it is respectively arranged at the middle part of backdoor inner plate ontology and lower part and traverses entire backdoor inner plate and concave
Concave station is reinforced at middle part and concave station is reinforced in bottom, forms the U-shaped beam structure to interior direction, is formed with tailgate outside plate larger
Cavity, inside cavity is suitably disposed with ribs, structure basic guarantee stiffness and strength of lower body on the whole；?
Concave station top is reinforced in bottom and the viscose glue boss that concave station top is provided with convex is reinforced at middle part, and the viscose glue boss and outside plate are logical
Glue bonding is crossed, supporting role is formed to outside plate, further promotes outside plate local stiffness and tailgate entirety stiffness.
Further, reinforce concave station at middle part and bottom is reinforced being provided with ribs on concave station, further strengthen intensity.
Further, wire harness passing-hole is offered in the middle part of facade structures.
Further, the reinforcement flange to bend inwards is provided on the hole wall of taillight mounting hole and rear door lock mounting hole,
To promote the local stiffness at aperture position, while avoiding direct aperture causes sharp keen edge exposed, guarantees assembly
Safety.
Further, which is formed using PP+GF material.
Automobile back door inner panel of the present invention, due to above structure, D column and backdoor inner plate ontology it is left and right under
The privileged sites such as angle, by setting facade structures and facade structures on flange respectively with the slot bottom of groove structure and two sides cell wall
Connection, the flange are equivalent to bridge floor, and facade structures are equivalent to bridge pier, the structure similar to bridge are integrally formed, in limited sky
In, effectively improve the stiffness of the weak location.It forms at the middle part of backdoor inner plate ontology and lower part to interior direction
U-shaped beam structure, form biggish cavity with tailgate outside plate, on the whole basic guarantee backdoor inner plate ontology middle and lower part
Stiffness and strength, by viscose glue boss to outside plate formed supporting role, further improve outside plate local stiffness and tailgate be whole
Body stiffness.The present invention strengthens the rigidity of automobile back door inner panel weakness well, effectively promotes the entirety of plastics back door
Under the premise of rigidity, while realizing lightweight, at the same have both good appearance, it is compact-sized rationally, reliable performance the advantages that.
