Summary of the invention
It is an object of the invention to provide a kind of automobile back door inner panel, on the premise of it can effectively promote the integral rigidity of plastics back door, realize lightweight simultaneously.
Automobile back door inner panel of the present invention, including backdoor inner plate body, windshield transmission region hole is offered on the top of backdoor inner plate body, the region being positioned at both sides, windshield transmission region hole is the D post in trench structure, taillight installing hole and rear door lock installing hole is offered in the middle and lower part of backdoor inner plate body, D post is provided with facade structures, this facade structures is left, right edge and inner side edge respectively with the left side of D post groove structure, right cell wall and bottom land connect, the outer side edges of facade structures is provided with flange, the two ends of flange respectively with the left side of D post, right cell wall connects.
Further, at the lower left corner and the lower right corner of backdoor inner plate body, also there is groove structure, it is also equipped with facade structures in this groove structure, the left and right side of this facade structures and inner side edge are connected with left and right cell wall and the bottom land of D post trench structure respectively, being provided with flange in the outer side edges of facade structures, the two ends of flange are connected with the left and right cell wall of D post respectively.
Further, it is respectively arranged with at the middle part of backdoor inner plate body and bottom and traverses whole backdoor inner plate and the middle part reinforcement concave station concaved and bottom reinforcement concave station, define in car direction U-shaped beam structure, bigger cavity is formed with tailgate outside plate, inside cavity is suitably disposed with ribs, the rigidity of this structure basic guarantee on the whole time body and intensity；Strengthening concave station top and middle part to strengthen concave station top be provided with cambered outwards viscose glue boss in bottom, this viscose glue boss is bonding by glue with outside plate, and outside plate is formed supporting role, promotes outside plate local stiffness and tailgate entirety stiffness further.
Further, strengthen concave station at middle part and bottom is strengthened being provided with ribs on concave station, strengthen intensity further.
Further, the middle part in facade structures offers wire harness passing-hole.
Further, the hole wall of taillight installing hole and rear door lock installing hole is provided with the reinforcement flange bent inwards, to promote the local stiffness at aperture position, avoids direct perforate simultaneously and cause sharp keen edge to expose, it is ensured that the safety of assembling.
Further, this backdoor inner plate body uses PP+GF material molding.
Automobile back door inner panel of the present invention, owing to having said structure, the privileged sites such as the left and right inferior horn at D post and backdoor inner plate body, it is connected with bottom land and the both sides cell wall of groove structure respectively by arranging the flange in facade structures and facade structures, this flange is equivalent to bridge floor, and facade structures is equivalent to bridge pier, and the structure that be similar to bridge is integrally formed, in limited space, it is effectively improved the stiffness of this weak location.Define at the middle part of backdoor inner plate body and bottom in car direction U-shaped beam structure, bigger cavity is formed with tailgate outside plate, the rigidity of basic guarantee backdoor inner plate body middle and lower part and intensity on the whole, by viscose glue boss, outside plate is formed supporting role, improve outside plate local stiffness and tailgate entirety stiffness further.The present invention well strengthens the rigidity of automobile back door inner panel weakness, on the premise of effectively promoting the integral rigidity of plastics back door, realizes lightweight simultaneously, has the advantage such as good looking appearance, reasonable, the dependable performance of compact conformation concurrently simultaneously.
