Abstract
Description
Technical Field
[0001] This utility model relates to the field of sunroof front glass technology, and in particular to a sunroof front glass assembly. Background Technology
[0002] In the field of vehicle components, the traditional sunroof windshield structure is extremely complex, containing numerous delicate and interoperable parts, such as complex frame structures, cumbersome sealing components, and various linkage parts. These parts are not only diverse in type, but also have high requirements for shape and dimensional precision, making them difficult to manufacture. This results in the current use of a large amount of PU edging and a large area of plastic-coated windshield, which increases the overall weight and is not conducive to lightweight design. Utility Model Content
[0003] The purpose of this utility model is to solve the problem mentioned in the background art that the components are not only diverse in type, but also have high requirements for their shape and size accuracy, making them difficult to manufacture. This results in a large amount of PU edging used and a large front glass area of the plastic-coated glass, which increases the total weight and is not conducive to lightweight design.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A sunroof front glass assembly includes a front glass pane, the front glass pane being wrapped with PU edging. Metal components connected by the PU edging are provided on the front and rear sides of the front glass pane. The metal components are slender rods with a hollow structure and a rectangular cross-section. Metal plates connected by PU edging are provided on the left and right sides of the front glass pane. The left metal plate has a near-7-shaped cross-section and is elongated in the front-rear direction. The right metal plate is symmetrically arranged with respect to the left metal plate about the front glass pane. Each metal plate includes an integral horizontal plate and a vertical plate. The left and right sides of the PU edging respectively wrap the corresponding horizontal plate, and the horizontal plate is located outside the vertical plate.
[0006] Preferably, the metal part has positioning parts at both ends, and positioning holes are provided on the positioning parts, and openings corresponding to the positioning holes are provided on the PU edging.
[0007] Preferably, the vertical plate has multiple connecting holes distributed along its length.
[0008] Preferably, two pressure blocks are provided at the corner of the front side of the front glass sheet, which are fixed by PU edging.
[0009] Compared with the prior art, the present invention has the following beneficial effects:
[0010] The metal parts are positioned near the edge, which, while ensuring strength, reduces the amount of PU edging material used and increases the visible area of the glass. The left and right sides of the front glass sheet are set with the horizontal plates facing outwards, while the vertical plates remain unchanged, resulting in a smaller PU edging width, which also increases the visible area of the glass.
[0011] The rectangular structure of the metal parts increases strength, offering a more regular geometry and stable mechanical properties. Furthermore, the relatively regular shape of the rectangular metal parts facilitates mold design and manufacturing. Simultaneously, the reduction in PU edging material significantly increases the light-transmitting area of the corresponding glass.
[0012] The regularity of the metal sheet ensures a uniform PU edging layer, reduces curing and cooling time, improves production efficiency, and helps ensure consistent product quality. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.
[0026] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.
[0027] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.
[0028] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.
[0029] Please see Figures 1-10 A sunroof front glass assembly includes a front glass sheet 2, the front glass sheet 2 being wrapped with PU edging 1 around its perimeter. Metal parts 3 are provided on the front and rear sides of the front glass sheet 2, connected by the PU edging 1. The metal parts 3 are slender rods with a hollow structure and rectangular cross-section. The PU-wrapped position of the front metal parts 3 is located at the front, and the PU-wrapped position of the rear metal parts 3 is located at the rear.
[0030] The rectangular cross-section metal component 3 on the front side is positioned near the edge with its plastic coating. This ensures sufficient force output from the top of the glass while making the thickness of the PU edging 1 more uniform, reducing shrinkage, stress marks, and other appearance risks. Similarly, the rectangular cross-section metal component 3 on the rear side is also positioned near the edge with its plastic coating. This maintains sealing and cushioning performance while also making the thickness of the PU edging material more uniform, further reducing shrinkage. The positioning of the front and rear metal components 3 ensures strength while minimizing the width of the PU edging 1, thus using less PU edging 1 material, increasing the visible area of the glass. This not only reduces raw material costs but also lightens the overall weight of the sunroof glass structure, improving the modality of the glass assembly.
[0031] The rectangular structure of metal part 3 increases its strength, and it has a more regular geometric shape and stable mechanical properties; moreover, the relatively regular shape of the rectangular metal part 3 facilitates mold design and manufacturing. At the same time, due to the reduction of PU edging material 1, the corresponding light-transmitting area of the glass is significantly increased. Positioning parts 31 are provided at both ends of metal part 3, and positioning holes 32 are opened on the positioning parts 31. These holes correspond to the process positioning holes 32 on the production mold, and openings 11 corresponding to the positioning holes 32 are opened on the PU edging 1.
[0032] Metal plates 4 connected by PU edging 1 are provided on the left and right sides of the front glass sheet 2. The metal plate 4 on the left side has a cross-section of about 7 and is long and strip-shaped along the front-back direction. The metal plate 4 on the right side is symmetrically arranged with respect to the metal plate 4 on the left side about the front glass sheet 2. The metal plate 4 includes an integral horizontal plate 41 and a vertical plate 42. The left and right sides of the PU edging 1 respectively wrap the horizontal plate 41 on the corresponding side. The horizontal plate 41 is located outside the vertical plate 42 and faces outward. The orientation of the horizontal plate 41 is opposite to the direction towards the center of the front glass sheet 2. The vertical plate 42 has multiple connecting holes 43 distributed along its length. The connecting holes 43 are used to connect the sliding components on the slide rail. The sliding components are not shown in the figure.
[0033] The flatness of the horizontal plate 41 ensures a uniform PU edging layer 1, reducing curing and cooling time during production and improving production efficiency. It also reduces the risk of shrinkage in the PU edging layer 1, enhancing the product's appearance. The regularity of the metal plate 4 facilitates support, improving the stability and reliability of mold production and ensuring consistent product quality. By reducing the coverage area of the PU edging layer 1 material around the perimeter, the light-transmitting area of the glass is significantly increased. It also ensures the stability of the glass's ejection force.
[0034] Two pressure blocks 5 are installed at the corner of the front side of the original front glass sheet 2, which are fixed by PU edging 1. The pressure blocks 5 are symmetrically arranged, and the PU edging 1 fixes the upper side of the pressure blocks 5 through a plastic coating process. This arrangement has extremely high bonding strength, is not easy to separate, and ensures the overall structural stability of the pressure blocks 5. After installation, the pressure blocks 5 can more stably press down on the windbreak net.
[0035] 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.
