Vehicle skylight frame and manufacturing method thereof

Abstract

The invention discloses a vehicle skylight frame and a manufacturing method thereof. The vehicle skylight frame comprises a front cross bar, a pair of curved bars, and a pari of straight bars vertically connected with the two ends of the front cross bar through the curved bars, wherein, the front cross bar, the pair of curved bars, and the straight bars form an integral-forming U-shaped structure; each bar comprises a slide rail slot; and the outer side of the slide rail slot on the straight bar extends outwards by utilizing the slot wall of the slide rail slot, and forms a water drainage slot with the same depth as that of the slide rail slot. The manufacturing method of the vehicle skylight frame comprises a blanking step, a punching step, a cutting step, a stretch bending step, a shaping step and a checking step. The vehicle skylight frame and the manufacturing method thereof adopt an integral-forming structure that no joint exists between the front cross bar and the slide rail, thereby reducing the riveting amount, ensuring the size accuracy and the uniformity, and simultaneously reducing matching errors between the vehicle skylight frame and other part assemblies.

Description

technical field [0001] The invention relates to a vehicle sunroof frame used in the field of vehicle accessories and a manufacturing method thereof. Background technique [0002] With the rapid development of the automobile industry, the function and structure of automobile sunroofs have also experienced a process from purely aesthetic to a combination of aesthetics and practicality. The car sunroof has the following functions. First, it is convenient for ventilation. When the air in the car is dirty, it is simple and convenient to take a breath. When the vehicle is running, the airflow flows quickly inside the sunroof, forming a negative pressure on the sunroof to suck out the dirty air in the car , there will not be a lot of dust and pollution from the front car directly entering from the side windows; the second is to ease the ventilation, the car sunroof ventilation has little effect on the temperature change in the car, does not affect the function of the air conditione...

AI Technical Summary

Problems solved by technology

Existing sunroof frames for vehicles are formed by split connection of the front beam and two parallel slide rails, and then manufactured by riveting, sealing, bending, expansion and other processes, the process is cumbersome and complicated

Moreover, the above process forms a connection point at the connection between the front beam and the slide rails on both sides, and whether the connection point is qualified (breakage problem) is directly related to the subsequent assembly between the frame and other assemblies, and in many cases the connection point does not Unqualified, resulting in a low pass rate and leaving a quality hazard
