Description

Technical Field

[0001] This utility model relates to the field of automotive window technology, and in particular to a sunroof assembly. Background Technology

[0002] Most current automotive panoramic sunroof designs consist of two glass panels, one in the front and one in the rear, designed to provide a wider field of vision and enhance passenger comfort. In addition to the two glass panels, a panoramic sunroof also includes a sunshade located at the rear of the car. The pull end of the sunshade is positioned below the rear glass sunroof. When the panoramic sunroof is open, the rear end of the front glass assembly tilts upwards and then moves backwards, moving the rear side of the front glass assembly above the rear glass sunroof. The front glass assembly continues to move backwards, causing the rear glass sunroof to first descend and then move backwards along with the panoramic sunroof.

[0003] However, most existing panoramic sunroofs rely on a linkage structure for their rear glass sunroof lowering mechanism. This linkage structure typically consists of multiple linkages, connectors, and complex mechanical transmission components. These components work together to lower the rear glass sunroof. Over long-term use, the linkages may gradually deform due to frequent tensile and compressive stresses, leading to problems such as jamming or tilting during the lowering of the rear glass sunroof. Utility Model Content

[0004] The purpose of this invention is to solve the problem mentioned in the background art that, during long-term use, the connecting rod may gradually deform due to frequent tensile and compressive stresses, leading to problems such as jamming and tilting when the rear sunroof descends.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A sunroof assembly includes a sliding rail with a first sliding groove. A rear mechanism assembly is mounted on the sliding rail and connected to a rear glass assembly. The rear mechanism assembly includes a rear glass bracket and a rear slider. A second rear slider is rotatably connected to the rear side of the first rear slider. The first rear slider has an inclined first sliding groove. The upper side of the rear glass bracket is fixed to the rear glass assembly, and a sliding pin inserted into the first sliding groove is fixed to the lower side of the rear glass bracket. A first limiting plate is fixedly connected to the first rear slider, and a second limiting plate is fixedly connected to the second rear slider. The second rear slider has a second sliding groove, and a third sliding pin is provided on the rear glass bracket and inserted into the second sliding groove.

[0006] Preferably, the lower side of the sliding groove two has a recessed section.

[0007] Preferably, rubber blocks that contact the rear glass bracket are installed on the rear slider one, the limiting plate one, the rear slider two, and the limiting plate two.

[0008] Preferably, the feature is that: a connecting shaft is fixed on the first limiting plate, and a connecting shaft is fixed on the second limiting plate.

[0009] Preferably, a front mechanism assembly is provided on the slide rail, and a connecting member is provided between the front mechanism assembly and the rear slider. The connecting member includes a connecting rod fixed to the front mechanism assembly and a connecting block rotatably connected to a connecting shaft. A torsion spring is sleeved on the connecting shaft. One end of the torsion spring abuts against the connecting block, and the other end abuts against a limiting plate. A connecting groove for the connecting rod to enter is provided on the connecting block. A limiting groove is provided on the slide rail, and a limiting protrusion for inserting into the limiting groove is provided on the lower side of the connecting block.

[0010] Preferably, the rear end of the rear glass bracket is rotatably connected to a support arm, the support arm has a rear sliding foot one and a rear sliding foot two, a support block is fixed on the slide rail, the support block has a support groove, the rear sliding foot one is located in the support groove, the slide rail has a slide groove two, and the rear sliding foot two is slidably connected to the slide groove two on the slide rail.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The rear mechanism assembly, through the combined structure of rear slider one, rear slider two, limiting plate one, and limiting plate two, prevents the rear sunroof from tilting or shifting to one side during sliding. Simultaneously, limiting plate one fixes rear slider one via connecting shaft one, and limiting plate two fixes rear slider two via connecting shaft two, further enhancing the connection stability between components and preventing loosening. Rubber blocks that contact the rear glass bracket are installed on the rear slider one, limit plate one, rear slider two, and limit plate two. The rubber blocks are symmetrically distributed on both sides of the rear glass bracket, which can directly limit the left and right swaying space of the rear glass bracket, reduce the vibration of the rear glass sunroof during movement or use, and improve the stability of the overall structure.

[0012] The use of parts is reduced by the cooperation of sliding pin and sliding groove 1, and the stability of the structure is increased. When the front mechanism component moves backward, the rear slider 1 is unlocked by the connecting part. The whole process does not require additional manual operation. Attached Figure Description

[0027] Please see Figures 1-8 A sunroof assembly includes a slide rail 1 with a sliding groove 11. A rear mechanism assembly 3 is symmetrically arranged on the slide rail 1. A rear glass assembly 2 is connected to two rear mechanism assemblies 3. Each rear mechanism assembly 3 includes a rear glass bracket 31 and a rear slider 32. A rear slider 36 is rotatably connected to the rear side of the rear slider 32, and the rear slider 36 is rotatably connected to the rear slider 32 to accommodate the curved slide rail 1. An inclined sliding groove 34 is formed on the rear slider 32. The upper side of the rear glass bracket 31 is fixed to the rear glass assembly 2, and a sliding pin 35 inserted into the sliding groove 34 is fixed to the lower side of the rear glass bracket 31. A sliding groove 39 is formed on the rear slider 36, and another sliding pin 35 is provided on the rear glass bracket 31 to be inserted into the sliding groove 39. The lower side of the sliding groove 39 has a recessed section 391. Both the sliding groove 34 and the sliding groove 39 have horizontal sections.

[0028] A limiting plate 37 is fixedly connected to the rear slider 32, and a limiting plate 38 is fixedly connected to the rear slider 36. The rear sliders 32 and 36 are located on one side of the rear glass bracket 31, while the limiting plates 37 and 38 are located on the other side of the rear glass bracket 31. The rear sliders 32, 36, 37, and 38 are all slidably connected to the slide groove 11.

[0029] Rubber blocks 33 that contact the rear glass bracket 31 are installed on the rear slider 32, the limiting plate 37, the rear slider 36, and the limiting plate 38. The rubber blocks 33 are located on both sides of the rear glass bracket 31 to prevent the rear glass bracket 31 from swaying left and right.

[0030] A connecting shaft 371 is fixed on a limiting plate 37. Two connecting shafts 371 are provided to fix the rear slider 32. A connecting shaft 381 is fixed on a limiting plate 38. Two connecting shafts 381 are provided to fix the rear slider 36.

[0031] A front mechanism assembly 7 is provided on the slide rail 1. A connecting member 4 is provided between the front mechanism assembly 7 and the rear slider 32. The connecting member 4 includes a connecting rod 41 fixed to the front mechanism assembly 7 and a connecting block 42 rotatably connected to the connecting shaft 371. The connecting rod 41 is fixed to the rear end of the front mechanism assembly 7. The front mechanism assembly 7 is used for the tilting and rearward movement of the front glass assembly 8. The front mechanism assembly 7 is prior art and will not be described further. A torsion spring 43 is sleeved on the connecting shaft 371. One end of the torsion spring 43 abuts against the connecting block 42, and the other end abuts against the limiting plate 37. A connecting groove 44 is provided on the connecting block 42 for the connecting rod 41 to enter. The connecting groove 44 is inclined. A limiting groove 12 is provided on the slide rail 1. A limiting protrusion 45 for inserting into the limiting groove 12 is provided on the lower side of the connecting block 42. Upon return, the connecting rod 41 drives the connecting block 42, causing the rear slider 32 to move forward. When the limiting protrusion 45 reaches above the limiting groove 12, the connecting groove 44 causes the limiting protrusion 45 to engage within the limiting groove 12. The torsion spring 43 applies a downward force to the connecting block 42 to prevent the limiting protrusion 45 from disengaging from the limiting groove 12 when the sunroof is closed.

[0032] A support arm 5 is rotatably connected to the rear end of the rear glass bracket 31. The support arm 5 has a first rear sliding foot 51 and a second rear sliding foot 52. A support block 6 is fixed on the slide rail 1, and the support block 6 has a support groove 61. The first rear sliding foot 51 is located within the support groove 61. The slide rail 1 has a second sliding groove 13, and the second rear sliding foot 52 is slidably connected to the second sliding groove 13 on the slide rail 1. The lower end of the support groove 61 communicates with the second sliding groove 13, allowing the first rear sliding foot 51 to enter the second sliding groove 13 from the support groove 61. The support arm 5 provides support for the rear glass bracket 31 in both the front-to-back and longitudinal directions.

[0033] During use, as the front mechanism assembly 7 moves backward, the raised portion of the front glass assembly 8 moves to the upper side of the rear glass assembly 2. When the connecting rod 41 enters the connecting groove 44 and continues to move backward, the connecting rod 41 causes the connecting block 42 to rotate upward through the inclined surface of the connecting groove 44, so that the connecting rod 41 is located in the connecting groove 44. The torsion spring 43 deforms, and the limiting protrusion 45 leaves the limiting groove 12. The connecting rod 41 pushes the connecting block 42 backward, and the connecting block 42 causes the rear slider 1 32, the rear slider 2 36, the limiting plate 1 37, and the limiting plate 2 38 to move backward together. The sliding groove 1 34 of the rear slider 1 32 causes the front end of the rear glass bracket 31 and the rear glass assembly 2 to descend first through the sliding pin 35. At this time, the rear glass bracket 31 and the support arm 5 rotate. The connection point is the pivot point. When the rear sliding pin 35 enters the lower section 391 and slides, the rear end of the rear glass assembly 2 also descends. At this time, the front sliding pin 35 is the pivot point. When the rear glass bracket 31 descends, the support arm 5 and the rear glass bracket 31 rotate relative to each other, causing the support arm 5 to move backward. The second rear sliding foot 52 slides in the second slide groove 13, while the first rear sliding foot 51 on the support arm 5 enters the second slide groove 13 from the support groove 61. The first rear sliding foot 51 and the second rear sliding foot 52 are located in the second slide groove 13 and limit the rear glass bracket 31, so that the rear glass bracket 31 stops descending. The lower section 391 causes the rear glass assembly 2 to move backward together through the sliding pin 35, and the first rear sliding foot 51 and the second rear sliding foot 52 slide in the second slide groove 13 at the same time. Upon return, the front mechanism assembly 7 drives the connecting rod 41 forward. The torsion spring 43 causes the limiting protrusion 45 to contact the bottom of the slide groove 11, thereby allowing the connecting rod 41 to drive the connecting block 42 forward. The connecting block 42 moves the rear slider 32 forward, and the rear sliding feet 51 and 52 keep the rear glass bracket 31 in a lowered state. The sinking section 391 moves the rear glass bracket 31 forward together with the sliding pin 35. When the rear sliding foot 51 contacts the support groove 61, it is blocked, and the rear glass bracket 31 and the rear glass assembly 2 stop moving. Then, the connecting rod 41, through the connecting block 42, moves the rear slider 32, the rear slider 36, and the limiting protrusion 11 forward. Plate 1 37 and limiting plate 2 38 continue to move forward, causing the rear glass assembly 2 to move upward through the sliding pin 35. The rear glass assembly 2 causes the rear sliding foot 1 51 to enter the support groove 61 and slide. The rear sliding foot 2 52 continues to move forward, causing the rear end of the rear glass assembly 2 to rise and reset. Then, it continues to move forward, and the front end of the rear glass assembly 2 rises and resets. The rear slider 1 32 continues to move forward. When the limiting protrusion 45 reaches above the limiting groove 12, the connecting rod 41 moves forward, generating a downward component force through the connecting groove 44, causing the limiting protrusion 45 to rotate downward and lock into the limiting groove 12. The connecting rod 41 continues to move forward and separates from the connecting block 42, and the rear glass assembly 2 remains stable.

[0034] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
