Abstract
Description
Technical Field
[0001] This utility model relates to the field of sunroof rear glass technology, and in particular to a sunroof rear glass assembly. Background Technology
[0002] In the field of vehicle components, the traditional rear glass structure of a sunroof is extremely complex, encompassing a large number of delicate and interlocking parts, including intricate frame structures, complex sealing components, and various interconnected parts. These parts are diverse, with stringent requirements for their shape and dimensional accuracy, making them extremely difficult to manufacture. Furthermore, the extensive use of PU edging to wrap the front and rear metal panels increases the overall weight, and since modality is inversely proportional to weight, this situation is detrimental to the modality of the glass assembly. Utility Model Content
[0003] The purpose of this invention is to solve the problem mentioned in the background art that the U-shaped edge wrapping of the front and back metal plates uses a lot of material, which increases the total weight. Since the modality is inversely proportional to the weight, this situation is not conducive to the modality of the glass assembly.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A sunroof rear glass assembly includes a rear glass pane, the rear glass pane being wrapped with PU edging and plastic coating around its perimeter. A front metal plate connected to the front side of the rear glass pane via the PU edging and plastic coating is provided on the front metal plate, which has a front drainage channel. A rear metal plate connected to the rear side of the rear glass pane via the PU edging and plastic coating is provided on the rear metal plate, which has a rear drainage channel. Multiple connectors connected to the left and right sides of the rear glass pane via the PU edging and plastic coating are provided. The connectors on the left and right sides of the rear glass pane are symmetrically distributed. Each connector includes a horizontal plate and a vertical plate, and the horizontal plate is wrapped with PU edging and plastic coating.
[0006] Preferably, the front metal plate and the rear metal plate are fixed to the lower surface of the PU edging.
[0007] Preferably, the front metal plate includes a front horizontal plate one, a front horizontal plate two, a front horizontal plate three, a front horizontal plate four, and a front vertical plate. The heights of the front horizontal plate one, the front horizontal plate two, the front horizontal plate three, and the front horizontal plate four decrease sequentially. The front horizontal plate one, the front horizontal plate two, the front horizontal plate three, the front horizontal plate four, and the front vertical plate are connected sequentially by different arc-shaped plates.
[0008] Preferably, the rear metal plate includes a rear horizontal plate one, a rear vertical plate one, a rear horizontal plate two, and a rear vertical plate two. The height of the rear horizontal plate two is lower than that of the rear horizontal plate one. The rear horizontal plate one, the rear vertical plate one, the rear horizontal plate two, and the rear vertical plate two are connected in sequence by different arc-shaped plates. Both the front water channel and the rear water channel are arched.
[0009] Preferably, the vertical plate has a connecting hole.
[0010] Preferably, the PU edging extends to the front and rear sides with connecting portions, the front connecting portion connecting to the end of the front metal plate and the rear connecting portion connecting to the end of the rear metal plate.
[0011] Preferably, strip-shaped sealing strips are installed on the front, left and right sides of the PU edging, and connecting sealing strips are installed at the corners of the PU edging.
[0012] Preferably, the PU edging is provided with mounting grooves for mounting strip sealing strips and connecting sealing strips.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] The connecting parts on both sides of the rear glass sheet adopt split small ear pieces to reduce the weight and cost of the connecting parts and reduce the amount of PU edging. The front and rear metal plates adopt a semi-enclosed external metal plate method to reduce the amount of PU edging material and reduce costs. The front and rear metal plates have large moments of inertia and good glass assembly modes.
[0015] The PU edging works in conjunction with the U-shaped strip sealing strip to form an active waterproofing mechanism through the compression of the front and rear glass; the front drainage channel of the front metal plate and the rear drainage channel of the rear metal plate can guide water out along a specific path to avoid internal water accumulation, providing double protection to improve waterproofing reliability.
[0016] The rear metal panel is positioned further back, shortening the inner boundary and effectively increasing the glass light-receiving area, creating a brighter and more transparent environment inside the vehicle, and significantly improving ride comfort and visual experience.
[0017] The original single connector has been replaced with multiple individual and identical connectors. Each connector can be produced using a single mold, which greatly improves the versatility and interchangeability of the components, facilitates production management, maintenance and replacement, and inventory allocation, and reduces later maintenance costs.

[0033] Please see Figures 1-9 A sunroof rear glass assembly includes a rear glass pane 2, which is surrounded by a PU edging 1. A front metal plate 3 connected to the front of the rear glass pane 2 via the PU edging 1 is provided, and a front drainage channel 31 is provided on the front metal plate 3. A rear metal plate 4 connected to the rear of the rear glass pane 2 via the PU edging 1 is provided, and a rear drainage channel 41 is provided on the rear of the rear glass pane 2. The front metal plate 3 and the rear metal plate 4 are fixed to the lower surface of the PU edging 1. Reducing the use of PU edging 1 material directly reduces production costs. It includes front horizontal plate 1 32, front horizontal plate 2 33, front horizontal plate 34, front horizontal plate 4 35 and front vertical plate 36. The height of front horizontal plate 1 32, front horizontal plate 2 33, front horizontal plate 34 and front horizontal plate 4 35 decreases sequentially. Front horizontal plate 1 32, front horizontal plate 2 33, front horizontal plate 34, front horizontal plate 4 35 and front vertical plate 36 are connected sequentially by different arc-shaped plates. The front metal plate 3 is a one-piece plate. Front horizontal plate 4 35 is the bottom plate of the front water channel 31. Front horizontal plate 1 32, front horizontal plate 2 33 and front horizontal plate 34 are all connected to PU edging 1.
[0034] The rear metal plate 4 includes a rear horizontal plate 42, a rear vertical plate 43, a rear horizontal plate 44, and a rear vertical plate 45. The rear horizontal plate 44 is lower than the rear horizontal plate 42. The rear horizontal plate 42, rear vertical plate 43, rear horizontal plate 44, and rear vertical plate 45 are connected sequentially by different curved plates. The PU edging 1 extends downward to the rear horizontal plate 44. The rear metal plate 4 is a one-piece plate. The rear vertical plate 43, rear horizontal plate 44, and rear vertical plate 45 form the rear drainage channel 41. The PU edging 1 wraps the rear horizontal plate 42. Both the front drainage channel 31 and the rear drainage channel 41 are arched.
[0035] Both the front and rear sides of the PU edging 1 extend with connecting portions 11. The front connecting portion 11 connects to the end of the front metal plate 3, and the rear connecting portion 11 connects to the end of the rear metal plate 4. The front and rear connecting portions 11 have different structures. The tops of the two front connecting portions 11 connect to both ends of the front metal plate 3 for water guidance. Similarly, the two rear connecting portions 11 connect to both ends of the rear metal plate 4 for water guidance.
[0036] Strip sealing strips 5 are installed on the front, left and right sides of the PU edging 1. Connecting sealing strips 7 are installed at the corners of the PU edging 1. The PU edging 1 has a mounting groove 12 for installing the strip sealing strips 5 and connecting sealing strips 7. The two ends of the connecting sealing strips 7 are connected to the mounting groove 12. The two connecting sealing strips 7 and the three strip sealing strips 5 cooperate to form a U-shaped shape.
[0037] By combining the PU edging 1 with the strip sealing strip 5, an effective active waterproofing mechanism is formed by the squeezing action of the front and rear glass. When water penetrates into the front metal plate 3, the front water channel 31 of the front metal plate 3 allows the water to flow to the outside along the path of the front water channel 31, preventing water from accumulating inside and further enhancing the waterproofing effect.
[0038] The rear metal plate 4 is fixed to the lower surface of the PU edging 1, reducing the amount of PU edging 1 used while still meeting the actual functional requirements of the rear drainage channel 41. This arrangement simplifies the mold structure, reduces complex shapes and unnecessary details, and lowers the manufacturing difficulty and cost of the mold. The rearward placement of the rear metal plate 4 shortens the inner boundary of the PU edging 1, increases the light-receiving area of the rear glass sheet 2, and improves the passenger experience.
[0039] Multiple connectors 6 are provided on the left and right sides of the rear glass sheet 2, connected by PU edging 1. The connectors 6 are symmetrically distributed on the left and right sides of the rear glass sheet 2. Each connector 6 includes a horizontal plate 61 and a vertical plate 62. The PU edging 1 coats the horizontal plate 61, fixing it to the connector 6. The vertical plate 62 has connecting holes 63. The connecting holes 63 are used to connect sliding components on a slide rail (not shown in the figure). Compared to the original single piece, multiple individual and identical connectors 6 are used, greatly improving the versatility and interchangeability of the connectors 6. Identical individual connectors 6 can share a single mold for production.
[0040] 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.
