An error-proof sun visor hook structure

technical field

The utility model relates to an automobile interior decoration structure, in particular to an error-proof sunshade hook structure.

Background technique

The car sun visor is installed above the front of the main driver and the co-driver of the car to prevent the glare of the sun. When in use, it can be turned down to block the sun. When it is not in use, it can be turned up. On the sun visor hook on the car body, clamp the car sun visor to prevent it from falling down automatically. The car sun visor hook is generally positioned and fastened on the car body by screws and positioning pins, and the clamping shaft of the car sun visor is clamped by a card slot. Car sun visor hooks are divided into left type and right type for the main and passenger positions. In design, the screw hole groove and the offset direction of the positioning pin are generally used to distinguish the car sun visor hooks of the main and passenger positions. However, there are different offset directions between the screw hole slot and the positioning pin on the current car sun visor hook, but the position connection line between the screw hole slot and the positioning pin is basically perpendicular to the axis of the slot of the car sun visor hook. When the car sun visor hook is installed on the assembly line, it is easy to distinguish the offset direction of the screw hole groove and the positioning pin, resulting in the left and right interchangeable wrong installation, and after the car sun visor hook is installed on the car body, the appearance still looks relatively correct , it is still difficult to find the wrong installation in time. It is not until the car sun visor and the hook are trial-fitted in the inspection process that the wrongly installed hook is found to be wrongly installed when it interferes with the solid part of the end of the car sun visor clamp shaft due to the opposite offset direction of the screw hole groove and the positioning pin. It must be reworked from time to time, resulting in low production efficiency, large waste of labor costs, and even bad products flowing to the market due to missed inspections, which further has a negative impact on brand reputation. Therefore, it is necessary to improve the design to effectively control the problem of wrong installation of automobile sun visor hooks. The utility model whose publication number is CN201941551U discloses a kind of car sun visor fixing hook on August 24, 2011, relates to the fixing structure of car accessories. In view of the phenomenon that the hook shaft of the sun visor is easy to fall off from the hook when the car is running, the utility model proposes a fixing hook for the sun visor of the car, which includes a body with a positioning pin and a hook, and the hook opening below the body There is a hook shrapnel at the place, and the overall structure of the hook shrapnel, the body and the positioning pin is injection molded into one. The hook is designed with a shrapnel structure at the opening. When the hook is matched with the sun visor, after the plastic shrapnel is compressed, it can ensure reliable cooperation with the rotating shaft of the sun visor and is not easy to fall off. The stability of the sun visor is guaranteed, the strength of the product is improved, and it is beneficial to the matching connection with the sun visor. But this automobile sun visor fixing hook is not to solve the wrong installation problem of the left and right type hooks as the purpose of the invention, so the technical solution does not involve error-proofing measures.
