Abstract
The utility model discloses an inner car panel. An inner car door panel (1) is arranged on one side of an outer car door panel (2); the inner car door panel (1) consists of an inner panel front body (1a) and an inner panel back body (1b); the tail end of the inner panel front body (1a) is connected with the head end of the inner panel back body (1b); the wall thickness of the inner panel back body (1b) is 1.1-1.4mm; the wall thickness of the inner panel front body (1a) is 0.5-0.7mm; and the width ratio between the inner panel front body (1a) and the inner panel back body (1b) is 1:6-1:4. The inner car panel adopts a split car door inner panel structure, can ensure the strength of the front part of the car door inner panel, prevent the front part of the car door inner panel from being deformed because of the influence of the tensile of opening and closing a car door, can effectively reduce the weight of the whole car door, enable the gravitational load borne by a car door hinge to be small, thereby avoiding the sagging of the car door, and effectively ensuring the using effect and service life of the car door.
Description
Technical field
The utility model relates to a kind of car member, relates in particular to a kind of car inner panel.
Background technology
At present, automobile door panel generally is made of inner plate of car door and door skin, and both are the monolithic platy structure.Inner plate of car door is arranged at a side of door skin, and wall thickness is about 0.8mm.Edge, front, back edge and the lower edge of inner plate of car door are fixed with the corresponding sides of door skin respectively, and the front portion of inner plate of car door is connected with car vehicle frame gusset by hinge.The automobile door panel of above structure has the following disadvantages:
1, the front portion of inner plate of car door is connected with the vehicle frame gusset by hinge, in the process of switch car door, pulling force will be carried in the front portion of inner plate of car door, because the wall thickness of inner plate of car door is about 0.8mm, the wall thickness of inner plate of car door front portion is less than normal, strength deficiency, under the effect of switch car door pulling force many times, the front portion of inner plate of car door deforms easily, and sagging can appear in whole sedan door, and then influences the normal use of car door.
2, the wall thickness at inner plate of car door rear portion is bigger than normal, the raw material that not only expend are many, increased cost of production, and can cause the weight of car door integral body to strengthen, the car door gravity that hinge carried in the process of switch car door is bigger like this, phenomenons such as the inner plate of car door front portion is out of shape, the sedan door generation is sagging also can occur.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of can effectively prevent distortion, and avoids car door that sagging car inner panel takes place.
The technical solution of the utility model is as follows: a kind of car inner panel, side at door skin is provided with inner plate of car door, its key is: described inner plate of car door by interior plate front body and inner panel after body constitute, wherein the head end of body links to each other and fixing behind the tail end of interior plate front body and the inner panel, the wall thickness of plate front body is 1.1~1.4mm in described, the wall thickness of body is 0.5~0.7mm behind the inner panel, and the ratio of the width of body is 1: 6~1: 4 behind interior plate front body and the inner panel.
In the utility model, inner plate of car door adopts split-type structural, the wall thickness of body has nothing in common with each other behind interior plate front body and the inner panel, and the wall thickness of interior plate front body greater than inner panel after the wall thickness of body, so both guaranteed the intensity of inner plate of car door front portion, alleviate the weight of whole sedan door again, thereby effectively prevented the inner plate of car door distortion, and avoided car door generation sagging.The wall thickness of interior plate front body is advisable with 1.1~1.4mm, and too small then insufficient strength excessively not only there is no need, but also can cause waste of raw materials.The wall thickness of body is advisable with 0.5~0.7mm behind the inner panel, outside the too small specification that then exceeds common used material, and the selection inconvenience, intensity is also bad, excessive also the existence wasted raw-material problem, but also can strengthen the weight of car door, increases the load that body hinge carried in the switch car door process.The ratio of the width of body was advisable with 1: 6~1: 4 behind interior plate front body and the inner panel, and the too small body hinge that then is not easy to of ratio is installed, and the position intensity that the door hinge of buying car in installments is installed is also not enough, the excessive effect that alleviates car door weight that then do not reach of ratio.
The head end of body is superimposed behind the tail end of above-mentioned interior plate front body and the inner panel, and both are fixing by welding, and it is easy to engage like this, and it is firm to connect, and can effectively prevent to come off.
As preferably, above-mentioned in the wall thickness of plate front body be 1.2mm, the wall thickness of body is 0.6mm behind the inner panel, the ratio of the width of body is 1: 5 behind interior plate front body and the inner panel.
Beneficial effect: the utility model adopts split type inner plate of car door structure, can ensure the intensity of inner plate of car door front portion, prevents that the inner plate of car door front portion is subjected to the influence of switch car door pulling force and deforms; The utility model can also effectively alleviate the weight of whole sedan door, the gravity load that body hinge is carried is less, and then it is sagging to have avoided car door to take place, and has effectively ensured the result of use and the application life of car door, have be skillfully constructed, reasonable in design, implement characteristics such as easy.
