Description

Technical Field

[0001] This utility model relates to a car sunroof, specifically to a panoramic sunroof rear glass drive 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 rear glass drive mechanism that operates stably and can realize the lowering and opening of the rear glass.

[0007] The technical solution adopted by this utility model is: a panoramic sunroof rear glass drive mechanism, characterized in that: it includes a front drive block, a rear drive block, a drive block connecting rod, a rear glass front lifting arm, and a rear glass rear lifting arm.

After the front glass movement assembly 1 moves to the set position, the rear end of the front glass movement assembly 1 and the front end of the rear glass movement assembly 2 are connected together under the action of the hanging assembly 6. The front glass movement assembly 1 continues to slide backward, and the rear glass movement assembly 2 moves backward synchronously. The rear glass movement assembly 2 drives the rear glass to sink and slide backward to open.

[0032] In this embodiment, the front glass motion assembly 1 includes a main drive block 11, a front glass front lifting arm 12, and a front glass rear lifting arm 13. The front end of the main drive block 11 is provided with a front sliding groove that cooperates with the front glass front lifting arm 12, and the rear end is provided with a rear sliding groove that cooperates with the front glass rear lifting arm 13. The front end of the front glass is connected to the front glass front lifting arm 12 through the front glass front connecting arm 14, and the middle part of the front glass is connected to the front glass rear lifting arm 13 through the front glass rear connecting arm 15. The main drive block 11, the front glass front lifting arm 12, the front glass rear lifting arm 13, and the front glass 4 form a quadrilateral motion mechanism; the motor passes through... The flexible shaft drive assembly 01 drives the main drive block 11 to move, which in turn drives the front glass tilting arm 12 and the rear glass tilting arm 13 to tilt or close (for the specific principle of tilting, please refer to the tilting process of the patent "CN202411984152.X Outer Sliding Panoramic Sunroof Drive Structure"). During the opening of the front glass, after the front glass tilting arm 12 and the rear glass tilting arm 13 have tilted, they continue to slide backward. The motor drives the front glass motion assembly 1 to move horizontally backward along the upper slide rail 72 of the slide rail 7 through the flexible shaft drive assembly 01, and the front glass 4 gradually opens backward.

[0033] In this embodiment, the rear end of the front glass lifting arm 12 is fitted with the inner sliding sleeve 17 of the front glass and installed in the front sliding groove of the main drive block 11. The middle two sides are fitted with the outer sliding sleeves 16 of the front glass and installed in the sliding groove of the slide rail 7.

The top of the front glass rear lifting arm 13 is connected to the middle part of the front glass 4 through the front glass rear connecting arm 15.

[0035] During the opening of the front glass, as the front glass motion assembly 1 slides horizontally backward along the upper slide rail 72 of the slide rail 7, after sliding to the set position, the front glass motion assembly 1 is connected to the rear glass motion assembly 2 through the coupling assembly 3. The front glass motion assembly 1 continues to slide backward, driving the front drive block 21 to move. The front drive block 21 further drives the rear drive block 22 to move synchronously through the drive block connecting rod 23, thereby driving the rear glass front lifting arm 24 and the rear glass rear lifting arm 25 to complete the sinking action. Continuing to slide backward, the front glass motion assembly 1 drives the front glass 4 and the rear glass motion assembly 2 drives the rear glass 5 to slide backward synchronously until the front glass 4 and the rear glass 5 are fully opened.

[0036] Combination Figure 6-11 In this embodiment, the mounting assembly 6 includes a mounting buckle 61 disposed at the rear end of the front glass moving assembly 1 and an inner clip assembly 62 disposed at the front end of the rear glass moving assembly 2.
