Abstract
Description
Technical Field
[0001] This utility model relates to a car sunroof, specifically to a panoramic sunroof front and rear glass linkage mechanism. Background Technology
[0002] Panoramic sunroofs allow drivers to enjoy driving pleasure while the vehicle is in motion by opening the sunroof glass, offering benefits such as improved ventilation and increased sunlight penetration. Therefore, panoramic sunroofs, which are predominantly made of glass, are widely used in vehicle roofs.
[0003] Typically, a panoramic sunroof consists of a front glass and a rear glass. The front glass is slidably installed at the front of the sunroof opening, while the rear glass is fixedly installed at the rear. With this type of panoramic sunroof, only the front glass is open, while the rear glass remains fixed. Therefore, apart from a visual difference, there is no significant difference between this type of panoramic sunroof and a regular sunroof, and rear passengers cannot feel the sensation of the sunroof being open.
[0004] Patent (CN201811652808.2) discloses a double-glass, double-opening panoramic sunroof for automobiles and its operation method, including: front and rear glass assemblies, which slide back and forth by being connected to front and rear sliding components that can slide back and forth along a guide rail mechanism; the guide rail mechanism includes guide rails disposed on both sides of the sunroof opening; the inner sidewall of the guide rail is provided with a running groove and a front guide groove for the front sliding component to slide, and the outer sidewall of the guide rail is provided with a running groove and a rear guide groove for the rear sliding component to slide; the front and rear sliding components slide forward or backward in the front and rear guide grooves respectively, causing the rear part of the front glass assembly to tilt upward or slide backward as a whole to open, and causing the rear part of the rear glass assembly to tilt upward or lift upward as a whole; when the panoramic sunroof is open, the front glass assembly is configured to slide backward after the rear glass assembly is lifted towards the outside of the roof panel. This allows the front and rear glass assemblies to open simultaneously, increasing the opening stroke of the front glass.
[0005] The patented design requires both the front and rear glass assemblies to first tilt upwards (either by tilting or lifting the entire assembly) before sliding backwards to open the sunroof; and the front and rear glass assemblies move synchronously. This structure presents the following problems: 1. The front glass assembly needs to move above the rear glass assembly. After the rear glass assembly tilts upwards, the front glass assembly will inevitably be taller, significantly increasing the required height space and compromising the overall stability of the movement; 2. The synchronous movement of the front and rear glass assemblies, with the front glass assembly moving above the rear glass assembly, increases the overall height and the risk of movement interference. Utility Model Content
[0006] To solve the above problems, this utility model provides a panoramic sunroof front and rear glass linkage mechanism, which has a simple structure and stable operation.
