Abstract
The utility model discloses a kind of automobile back door assembly, to comprise on tailgate outside plate, backdoor inner plate, tailgate window frame reinforcement under reinforcement and tailgate window frame, corner on the window frame that on described tailgate window frame, reinforcement is welded on backdoor inner plate, under described tailgate window frame, reinforcement is welded on corner under the window frame of backdoor inner plate, the backdoor inner plate feet that described backdoor inner plate is provided with backdoor inner plate reinforced rib and welds with tailgate outside plate; Described automobile back door assembly also comprises backdoor inner plate support beam, the open box-like structure of this backdoor inner plate support beam to be cross section be " several " font, its flanging welded by left and right side, on backdoor inner plate reinforced rib, forms closed cavity body structure with backdoor inner plate reinforced rib.It can improve the rigidity of whole backdoor inner plate, and then improves bending stiffness, the torsional stiffness of tailgate assembly.
Description
Technical field
The utility model relates to a kind of automobile body components, is specifically related to a kind of automobile back door assembly.
Background technology
Closure member performance plays very important effect in vehicle performance, and in closure member, the structure design of tailgate assembly is a difficult point, and the quality of its structure design directly affects bending stiffness, resists the performances such as recessed and torsional stiffness.As shown in Figure 1, existing automobile back door assembly, comprise tailgate outside plate 1, backdoor inner plate 2, reinforcement 4 under reinforcement 3 and tailgate window frame on tailgate window frame, corner on the window frame that on tailgate window frame, reinforcement 3 is welded on backdoor inner plate 2, under tailgate window frame, reinforcement 4 is welded on corner under the window frame of backdoor inner plate 2, the backdoor inner plate feet 22 that backdoor inner plate 2 is provided with backdoor inner plate reinforced rib 21 and welds with tailgate outside plate 1, backdoor inner plate feet 22 is positioned at the middle part of backdoor inner plate 2, backdoor inner plate reinforced rib 21 is positioned at the right side of backdoor inner plate feet 22, backdoor inner plate 2 is connected with tailgate outside plate 1 by backdoor inner plate feet 22.
There are the following problems for this tailgate assembly: on tailgate window frame, under reinforcement and tailgate window frame, reinforcement can play obvious booster action to the window frame position of backdoor inner plate, but not obvious for the stiffening effect in the middle part of backdoor inner plate, it cannot improve the rigidity of backdoor inner plate self on the whole; Backdoor inner plate feet can support tailgate outside plate, but for size for the comparatively large and tailgate assembly of model curved surface complexity, due to the structural limitations by backdoor inner plate, it too much cannot design the backdoor inner plate feet welded with tailgate outside plate, a general only design backdoor inner plate feet in the middle part of backdoor inner plate, it is not enough to the reinforcement in the middle part of backdoor inner plate, thus causes the bending stiffness of tailgate assembly, torsional stiffness lower.
Summary of the invention
The purpose of this utility model is to provide a kind of automobile back door assembly, to improve the rigidity of whole backdoor inner plate, and then improves bending stiffness, the torsional stiffness of tailgate assembly.
Automobile back door assembly described in the utility model, to comprise on tailgate outside plate, backdoor inner plate, tailgate window frame reinforcement under reinforcement and tailgate window frame, corner on the window frame that on described tailgate window frame, reinforcement is welded on backdoor inner plate, under described tailgate window frame, reinforcement is welded on corner under the window frame of backdoor inner plate, the backdoor inner plate feet that described backdoor inner plate is provided with backdoor inner plate reinforced rib and welds with tailgate outside plate; Described automobile back door assembly also comprises backdoor inner plate support beam, the open box-like structure of this backdoor inner plate support beam to be cross section be " several " font, its flanging welded by left and right side, on backdoor inner plate reinforced rib, forms closed cavity body structure with backdoor inner plate reinforced rib.
Can better to fit with the face of weld of backdoor inner plate reinforced rib to make the face of weld of backdoor inner plate support beam and weld, the left side flange of described backdoor inner plate support beam has the non-solder face of multiple face of weld and multiple epirelief, and this face of weld and interval, non-solder face are uniformly distributed; The right side flange of described backdoor inner plate support beam has three face of weld spaced apart and the non-solder face of two epireliefs, and this non-solder face is positioned at the top of the right side flange of backdoor inner plate support beam.
In order to alleviate the weight of backdoor inner plate support beam, described backdoor inner plate support beam is provided with the lightening hole of strip shape.
The utility model by welding the mode of backdoor inner plate support beam on backdoor inner plate reinforced rib, booster action is served in the middle part of backdoor inner plate, the rigidity of whole backdoor inner plate is together improve with reinforcement and backdoor inner plate feet under reinforcement, tailgate window frame on tailgate window frame, and then improve bending stiffness, the torsional stiffness of tailgate assembly, the more complicated tailgate assembly of model curved surface can be adapted to the requirement of rigidity.
