The utility model belongs to the technical field of automobiles, in particular to a car door inner panel structure. It includes the door inner panel body, the door inner panel body includes a non-stamping area and a stamping area, and the stamping area includes a deep drawing area and a shallow drawing area of different drawing depths, between the deep drawing area and the shallow drawing area and the shallow drawing area There is a smooth transition between the area and the non-stamping area. The utility model effectively solves the problem of insufficient rigidity of the fixed point of the armrest bracket of the door guard, improves the performance of the inner panel of the car door, does not increase the cost and difficulty of the process, and has the characteristics of simple structure and strong practicability.
Description
Technical field
The utility model belongs to automobile technical field, is specifically related to a kind of car door back veneer structure.
Background technology
In the exploitation of new model, due to the restriction of environment part, due to the restriction of structure and technique, be prone to the defects such as low, the local attachment point poor rigidity of car door back veneer mode, so all need car door back veneer to carry out punching press, strengthen its rigidity.Existing car door back veneer is generally to need the position integral body of punching press to strike out the consistent degree of depth, be generally 8mm, punching press is simple and easy to realize, but at door shield armrest support attachment point, if still according to the punching press of 8mm thickness, cannot guarantee support attachment point rigidity, through experimental analysis support attachment point, at least need the above degree of depth of punching press 14mm can meet rigidity requirement; If but the whole punching press 14mm degree of depth not only increased cost, and Sheet Metal Forming Technology cannot realize.
Summary of the invention
The purpose of this utility model is exactly the deficiency existing in order to solve above-mentioned background technology, and a kind of car door back veneer structure that does not increase technology difficulty, can improve again door shield armrest support attachment point rigidity is provided.
The technical solution adopted in the utility model is: a kind of car door back veneer reinforced rib, comprise car door back veneer body, car door back veneer body comprises non-stamped area and stamped area, described stamped area comprises the deep-draw nip of different press depth and is positioned at the shallow Stamping Area of deep-draw nip both sides, equal rounding off between described deep-draw nip and shallow Stamping Area and between shallow Stamping Area and non-stamped area.
Further, the press depth of described deep-draw nip is 12-18mm, and the press depth of shallow Stamping Area is 6-10mm.
Further, described deep-draw nip is for the structure of fixed gate guard plate armrest support on car door back veneer body.
The utility model is divided into two different Stamping Areas of the depth by the stamped area of car door back veneer, deep-draw nip rigidity is applied to more by force the position that car door back veneer is needed reinforcement badly, shallow Stamping Area is applied to the general position of strengthening, actv. has solved the problem of door shield armrest support attachment point rigidity deficiency, both improved car door back veneer performance, do not increase cost and technology difficulty, there is simple in structure, reliable in function, practical feature yet.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is A-A cross-sectional view in Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, is convenient to be well understood to the utility model, but they do not form and limit the utility model.
As shown in Figure 1 and Figure 2, the utility model comprises car door back veneer body, and car door back veneer body is divided into two regions: non-stamped area 1 and stamped area 2.Described stamped area 2 comprises the deep-draw nip 21 of different press depth and is positioned at the shallow Stamping Area 22 of deep-draw nip both sides, and deep-draw nip 21 is for the structure of fixed gate guard plate armrest support on car door back veneer body.The press depth L1 of deep-draw nip 21 is 12-18mm,, 14mm preferably; The press depth L2 of shallow Stamping Area 22 is 6-10mm, preferably 8mm.Equal rounding off between deep-draw nip 21 and shallow Stamping Area 22 and between shallow Stamping Area 22 and non-stamped area 1.
Car door back veneer of the present utility model adopts different Stamping Areas, and each parts on car door back veneer are installed targetedly, for example, door shield armrest support attachment point is arranged to deep-draw nip, can solve the problem of existing guard plate armrest support attachment point poor rigidity.The utility model is divided into two different Stamping Areas of the depth by the stamped area of car door back veneer, deep-draw nip is applied to the position that car door back veneer is needed reinforcement badly, shallow Stamping Area is applied to the general position of strengthening, actv. has solved the problem of door shield armrest support attachment point rigidity deficiency, both improved car door back veneer performance, do not increase cost and technology difficulty, there is simple in structure, reliable in function, practical feature yet.
The content not being described in detail in this specification sheets belongs to the known prior art of professional and technical personnel in the field.
