Abstract
The invention relates to a vehicle door outer skin strengthening structure which comprises a vehicle door outer skin, an anticollision beam and a strengthening member. The strengthening member is vertically arranged at the center of the vehicle door outer skin. The edges at the first half part and the second half part of the strengthening member, which are toward one surface of the vehicle door outer skin, are respectively provided with a gluing groove in a pressing mode. Two opposite U-shaped structures are formed by the gluing grooves at the first half part and the second half part of the strengthening member. Expansion adhesives are coated in the grooves so as to fix the strengthening member with a vehicle door inner skin. The first half part of the strengthening member extends to the upper region of the vehicle door inner skin in the length direction. The second half part of the strengthening member extends to the lower region of the vehicle door inner skin in the length direction. The middle part of the strengthening member is transversely provided with a groove. The middle part of the anticollision beam is welded in the groove so as to press down the strengthening member. In the vehicle door outer skin strengthening structure, the strengthening member of the vehicle door outer skin is lengthened, so that the strengthening member of the vehicle door outer skin can be covered on the region with low intensity at the upper part of the outer skin and the region with low intensity of the whole outer skin is strengthened, thereby eliminating the strengthening member in the outer skin and achieving the effects of reducing the weight of a vehicle door and reducing the welding complexity of the vehicle door.
Description
Technical field
The present invention relates to the arrangements for automotive doors annex, be specifically related to door reinforced structure.
Background technology
Car door exterior skin rigidity is generally on the weak side, needs reinforcement to strengthen exterior skin rigidity.Reinforcement plays exactly and strengthens the effect of exterior skin rigidity under the arrangements for automotive doors exterior skin, and it is used for improving the rigidity of car door exterior skin by expansion glue supported cart covering outdoors.
Referring to Fig. 1, present automobile normally will be provided with in crashproof crossbeam 5, the car door exterior skin reinforcement 4 under the reinforcement 2 and car door exterior skin on car door exterior skin 1, wherein reinforcement 2 is a strip shape in the car door exterior skin, by expansion glue cross-tie car door exterior skin upper area, strengthen exterior skin upper area rigidity.Reinforcement 4 then is a dice structure under the car door exterior skin, and the one partial fixing is on car door anti-collision crossbeam 5, and another part supports the exterior skin lower area by expansion glue, strengthens exterior skin lower area rigidity.There is the welded structure complexity in existing this structure, shortcomings such as car door Heavy Weight.
Summary of the invention
The object of the present invention is to provide a kind of simple arrangements for automotive doors exterior skin additional strengthening, reduce car door weight and car door welding complexity.
Technical scheme of the present invention is as follows:
A kind of arrangements for automotive doors exterior skin additional strengthening, it comprises car door exterior skin, crashproof crossbeam and reinforcement, in car door exterior skin central region, and the front position of crashproof crossbeam is higher than the rear end by front frame and after poppet crosswise fixed at described crashproof crossbeam two ends; It is characterized in that: described reinforcement is a pane blanked part, described reinforcement vertically is provided with the central authorities of car door exterior skin, its first half and lower part are pressed with coating groove respectively towards the edge of car door exterior skin one side, the coating groove of the first half and lower part forms two relative U words, scribble expansion glue in the groove, reinforcement and car door inside panel are fixed, and the first half length of reinforcement is to car door inside panel upper area, and lower part length is to car door exterior skin lower area; Laterally there is a groove at the middle part of described reinforcement, and the middle part of crashproof crossbeam is welded in wherein, and reinforcement is pushed down.
The first half of described reinforcement and the centre of lower part have a lightening hole.
The present invention is by the length of lengthening car door exterior skin reinforcement, make car door exterior skin reinforcement can cover the weak zone of exterior skin upper strength, allow the zone that reinforcement can strengthen whole exterior skin weak strength under the exterior skin, guarantee exterior skin rigidity, so just, can cancel reinforcement in the exterior skin, reach the effect that reduces car door weight and car door welding complexity.

The specific embodiment
As shown in Figure 2, this car door exterior skin additional strengthening comprises car door exterior skin 1, crashproof crossbeam 5 and reinforcement 7, in car door exterior skin central region, and the front position of crashproof crossbeam 5 is higher than the rear end by front frame 6 and after poppet 3 crosswise fixed at crashproof crossbeam 5 two ends.
In conjunction with Fig. 2, Fig. 3 and Fig. 4 as seen, the present invention carries out supplied materials with reinforcement under the original car door exterior skin and improves, new reinforcement 7 is in order to guarantee the intensity of part, vertical section of this reinforcement adopts several fonts, simultaneously in order to guarantee that reinforcement under the car door exterior skin can farthest strengthen the rigidity of exterior skin, the shape of reinforcement is an oblong.This reinforcement 7 vertically is provided with the central authorities of car door exterior skin 1, its first half and lower part are pressed with coating groove 8 respectively towards the edge of car door exterior skin 1 one side, the coating groove 8 of the first half and lower part forms two relative U words, scribble expansion glue 9 in the groove, expansion glue is through the application workshop time, the high-temperature baking after expansion so prop up the car door exterior skin, plays the effect that strengthens exterior skin rigidity.These two U-shaped coating grooves are not only limited to and are coated with expansion glue usefulness, and the rigidity of reinforcement own is increased.The first half length of reinforcement 7 is to car door inside panel upper area, and lower part length is to car door exterior skin lower area, and laterally there is a groove at the middle part of reinforcement 7, and the middle part of crashproof crossbeam is welded in wherein, and reinforcement is pushed down.
The contour area of the reinforcement 7 after the improvement that the present invention adopts strengthens, and the width of coating groove 8 strengthens, thereby has increased the area that covers exterior skin, makes the weak zone of exterior skin rigidity all can obtain enhancing.In the improvement reinforcement is also adjusted to some extent in the layout of car door exterior skin, reinforcement 7 has been located at the central authorities of car door exterior skin, directly run through car door, guarantee to cover the weak zone of exterior skin upper area rigidity fully.Car door exterior skin reinforcement 7 after correcting one's mistakes just can replace in the preceding car door exterior skin of improvement reinforcement under the reinforcement and car door exterior skin, has made the weight saving of car door.
Have a lightening hole 10 at the first half of reinforcement 7 and the centre of lower part in addition, its effect is in the rigidity that guarantees the car door exterior skin weight of car door further to be alleviated.
The groove 11 of a U-shaped has been designed in the position of weld of this car door exterior skin reinforcement 7 and crashproof crossbeam, and reinforcement 7 just is fixed on the crashproof crossbeam 5 by protection weldering (being the position of freezing as the thick black line among Fig. 2), thereby makes them can fit better.
