Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive technology, and more specifically, to a welding assembly for the side panels of a front wall panel of an automobile. Background Technology
[0002] The sheet metal part located behind the engine and below the windshield of a car is the front side panel assembly, also known as the front bulkhead assembly. The front side panel assembly serves to provide support and connection, block the heat generated when the engine is running, and isolate the outside world from the interior of the vehicle, thus providing heat insulation, heat preservation, and dust prevention.
[0003] A search revealed that utility model patent CN212172361U discloses a welding assembly for a front wall panel of an automobile. The assembly includes a stamped groove on the outer periphery of a bent plate, with the opening of the groove facing a protective sleeve. An expansion sealing strip is disposed inside the stamped groove. The bent plate and the protective sleeve are sealed by the expansion sealing strip. The expansion strip fills the gap at the joint between the bent plate and the protective sleeve. Sealant is applied to the weld joint of the bent plate and the protective sleeve, ensuring the sealing performance of the front wall panel assembly. The sealant also isolates the weld joint from the outside environment, preventing oxidation and rust. Multiple second slots are provided at the connection point of the male buckle to the front wall panel, and multiple first slots are provided at the connection point of the female buckle to the support tray and connecting plate. The first and second slots prevent rotation of the male and female buckles.
[0004] However, the above patent still has the following shortcomings: when welding between the bending plate and the sheath, it is not convenient to position, which affects the uniformity of multiple front wall panel side panel welding assemblies and increases the difficulty of processing. Therefore, we propose an automotive front wall panel side panel welding assembly. Utility Model Content
[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a welding assembly for the side panels of the front wall of an automobile.
[0006] To solve the above problems, the present invention adopts the following technical solution: a welding assembly for a front wall panel of an automobile, comprising a partial front wall side panel and a partial connecting plate, wherein a bending plate is provided on the side of the partial front wall side panel, a stamping groove is provided on the side of the bending plate, an expansion sealing strip is sleeved in the inner cavity of the stamping groove, a protective sleeve is provided on the partial connecting plate, a positioning hole is provided on the side of the protective sleeve, a positioning boss is provided on the side of the bending plate, and the end of the positioning boss is movably sleeved into the inner cavity of the positioning hole.
[0007] As a preferred embodiment of this utility model, a sealing strip is provided at the top of the sheath.
[0008] As a preferred embodiment of this utility model, corner guards are provided on the partial front wall side plate.
[0009] In a preferred embodiment of this utility model, the partial front wall side plate and the partial connecting plate are both integrally stamped.
[0010] In a preferred embodiment of this utility model, the outer side of the bent plate and the inner side of the sheath are fitted together.
[0011] In a preferred embodiment of this utility model, the inner diameter of the positioning hole is equal to the outer diameter of the end of the positioning boss.
[0012] Compared with the prior art, the advantages of this utility model are as follows: In this utility model, a positioning boss is stamped out on the bent plate on the side of the partial front wall side plate, and a positioning hole is machined on the sheath side of the partial connecting plate. When the partial front wall side plate and the partial connecting plate are welded, the end of the positioning boss is inserted into the positioning hole. The positioning hole and the positioning boss are used to position the welding position between the partial front wall side plate and the partial connecting plate, ensuring the accuracy of the welding position between the partial front wall side plate and the partial connecting plate, while ensuring the efficiency of the welding process, and making it highly practical.
