AI Technical Summary

Technical Problem

The existing roof rack crossbar structure is fixed, which cannot be adapted to the irregular roof shapes of different car models. The installation stability is poor, and the telescopic adjustment function is limited, making it difficult to meet diverse usage needs.

Method used

Design a multi-functional luggage rack crossbar, comprising a main rod, left and right telescopic mechanisms, and front and rear moving mechanisms, to achieve synchronous movement and adjustment of the main rod and the left and right telescopic mechanisms, adapt to irregularly shaped vehicle roofs, and have a variety of adjustment methods.

Benefits of technology

It enables the crossbar to extend and retract freely in the front-to-back and left-to-right directions, adapting to the irregular roof shapes of different car models, improving installation compatibility and ease of use, optimizing user experience, and meeting diverse and personalized needs.

Abstract

This utility model provides a multifunctional roof rack crossbar, relating to the field of automotive parts technology. It includes a main rod, left and right telescopic mechanisms, and a front-to-back moving mechanism. The length of the main rod is parallel to the vehicle width direction, and its two ends are movably connected to the left and right telescopic mechanisms. The front-to-back moving mechanism is connected to the left and right telescopic mechanisms and movably connected to the roof rack sections located on both sides. The front-to-back moving mechanism can drive the main rod and the left and right telescopic mechanisms to move synchronously to adjust their relative front-to-back position to the roof rack sections. Simultaneously, the left and right telescopic mechanisms can move relative to the main rod along the vehicle width direction. When the roof rack section is irregularly shaped, the left and right telescopic mechanisms can move relative to the main rod along the vehicle width direction while moving back and forth, thus adapting to the deformation of the roof rack section. This allows for simultaneous free extension and retraction in both front-to-back and left-to-right directions, providing a variety of adjustment methods to accommodate various irregularly shaped roofs of different vehicle models, improving installation adaptability and ease of use.
