New energy automobile air return grille and manufacturing method thereof

Abstract

The invention relates to the technical field of automobile air return grilles, in particular to a new energy automobile air return grille and a manufacturing method of the new energy automobile air return grille. The new energy automobile air return grille comprises a grille plate, two short edge materials and two long edge materials, and the two long edge materials are oppositely arranged on the two long edges of the grille plate; the two short side materials are oppositely arranged on the two short sides of the grating plate, and the grating plate is arranged between the two long side materials and the two short side materials. First screw holes are respectively formed in the two ends of the long edge material; connecting pieces capable of being inserted into one end of the interior of the long sapwood are arranged at the two ends of the short sapwood correspondingly, and second screw holes capable of being in butt joint with the first screw holes are formed in the connecting pieces; limiting strips distributed in the length direction of the long sapwood are arranged on the inner side of the long sapwood, strip-shaped limiting grooves matched with the limiting strips are formed in the long edge of the grating plate, and the technical problems of how to facilitate assembly during production and how to automatically assemble are solved.

Description

technical field [0001] The invention relates to the technical field of vehicle air return grilles, in particular to a new energy vehicle air return grill, and in particular to a manufacturing method of a new energy vehicle air return grill. Background technique [0002] New energy vehicles refer to the use of unconventional vehicle fuels as power sources or the use of conventional vehicle fuels, the use of new vehicle power units, and the integration of advanced technologies in vehicle power control and drive, resulting in advanced technical principles and new technologies. , The new structure of the car. [0003] At present, the air return grilles used in new energy vehicle air conditioners are usually made of metal profiles by cutting and tailoring, which requires a combination of tailoring and grinding. The disadvantage is that tailoring is troublesome, and in In the production process, manual assistance is required for assembly, which cannot be fully automated, thus aff...

AI Technical Summary

Problems solved by technology

[0003] At present, the return air grilles used in new energy vehicle air conditioners are usually made by cutting and tailoring metal profiles, and a combination of tailor welding and grinding is required during production; the disadvantage is that tailor welding is troublesome, and in In the production process, manual assistance is required for assembly, which cannot be fully automated, thereby affecting manufacturing efficiency. Therefore, we propose a new energy vehicle return air grille and its manufacturing method in order to solve the above-mentioned problems
