Furthermore, structural adhesive can be added to the structure to be matched with the structure for use, so that the rigidity and the strength of the structure are enhanced, and the welding spots are prevented from falling off, namely, the structural adhesive is coated on the first boss 22 and the first concave part 12 or the structural adhesive is coated in one of the first boss 22 and the first concave part 12 independently between the forming of the welding spots 3. The structure fit mode of the first boss 22 and the first concave part 12 is adopted, the first concave part 12 is equivalent to a collecting tank, the problem that structural adhesive splashes when the first boss 22 and the first concave part 12 are connected to affect the appearance of welding spots can be avoided, meanwhile, compared with the structure adhesive coated between two planes, the first concave part 12 is coated with the structural adhesive, the coating amount of the structural adhesive is more, the connection between the reinforcing plate 1 and the door inner plate 2 is further improved, and the rigidity and strength are improved.
In addition, the first boss 22 may be provided as follows:
the number of the first bosses 22 may be plural, and corresponds to one first recess 12, where the first recess 12 is provided with plural solder joint holes, and the corresponding solder joint 3 is formed and arranged as follows:
first, a welding spot hole is formed in the first recess 12, and when a welding device such as a welder or a welding gun is used, a welding operation is performed in the welding spot hole to form a welding spot.
The second is the setting on the basis of first kind, and the one end that first boss 22 and first depressed part 12 contacted is equipped with the depressed part, is equipped with the arch in the centre of depressed part, and the protruding solder joint hole of seting up in passing first depressed part 12 is through this kind of mode reinforcing connection stability between the two.
The principle of the present application:
(1) The joint of the reinforcing plate 1 and the door inner plate 2 is provided with a first plane lap joint part 10 and a first curved surface lap joint part 11 along the length direction and the width direction of the automobile body respectively, so that welding spots 3 are distributed on the length direction and the width direction of the automobile body, in the opening and closing process of the door inner plate, the stress at the welding spots 3 of the door inner plate 2 and the reinforcing plate 1 is released in two directions, and the force born by the welding spots is dispersed on the length direction and the width direction of the automobile body, so that the risk that the welding spots at the lower end of the side of the automobile door close to the door lock are easy to fall off is avoided.
In addition, the joint of the reinforcing plate 1 and the door inner plate 2 is provided with the first plane lap joint part 10 and the first curved surface lap joint part 11 along the length direction and the width direction of the vehicle body respectively, so that the arrangement of the first plane lap joint part and the first curved surface lap joint part is not influenced by the narrow cavity of the door inner plate 2, and meanwhile, the risk that welding spots fall off when the weight of the vehicle door is not increased, the closing impact of the vehicle door is effectively reduced, and the cost is reduced to a certain extent.
