Embodiment Construction
[0014] Such as figure 2 As shown, the door outer skin reinforcement structure includes the door outer skin 1, the anti-collision beam 5 and the reinforcement 7, and the two ends of the anti-collision beam 5 are laterally fixed in the middle area of the door outer skin through the front bracket 6 and the rear bracket 3, And the front end of the anti-collision beam 5 is higher than the rear end.
[0015] combine figure 2 , image 3 and Figure 4 It can be seen that the present invention improves the original reinforcement under the outer skin of the car door with incoming materials. In order to ensure the strength of the parts, the new reinforcement 7 adopts a few-shaped longitudinal section. To maximize the rigidity of the outer skin, the shape of the stiffener is a rectangle. The reinforcing member 7 is vertically arranged in the center of the door outer skin 1, and its upper half and lower half are respectively pressed with glue coating grooves 8 on the edges facing t...

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. Inthe 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 [0001] The invention relates to an automobile door accessory, in particular to a car door reinforcement structure. Background technique [0002] The stiffness of the outer skin of the car door is generally weak, and reinforcements are needed to enhance the stiffness of the outer skin. The reinforcement under the outer skin of the car door is used to enhance the stiffness of the outer skin. It supports the outer skin of the door through the expansion rubber to increase the stiffness of the outer skin of the door. [0003] see figure 1 , the current automobile usually sets the anti-collision beam 5, the middle reinforcement 2 of the outer door skin and the lower reinforcement 4 of the outer door skin on the outer door skin 1, wherein the middle reinforcement 2 of the outer door skin is a long strip The upper area of the outer skin of the door is laterally supported by the expansion glue to enhance the rigidity of the upper area of the outer skin. The rei...
