Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0051] To add a sunroof to a car roof that originally did not have one, the roof panel 1 is first cut to create a sunroof window 11. Then, the modification frame 2 provided in the following embodiment is installed on the sunroof window 11. Finally, the existing sunroof assembly 3 (such as...) is then installed... Figures 1 to 3 , Figure 10 The diagram shows a sunroof assembly 3, which includes a sunroof glass component 31, a sunroof frame component 32, and a sunroof sunshade component 33. Other existing technologies also include models without the sunroof sunshade component 33. This assembly is mounted on a modification frame 2, and the sunroof assembly 3 is then added to the sunroof opening 11 via the modification frame 2. Figure 1 , Figure 2 This achieves the goal of adding a sunroof to the roof of the vehicle.

[0052] Regarding the modified frame, Example 1 is given here:

[0053] Reference Figures 4 to 6 The modified frame 2 includes an annular mounting frame 21, an annular sealing strip 22, and two strip-shaped load-bearing beams 23.

[0054] Regarding installation box 21:

[0055] like Figure 7 The mounting frame 21 has a ring-shaped mounting plate 211. The ring-shaped design of the mounting plate 211 creates a mounting window 212 on the inner side of the mounting plate 211. The mounting window 212 is used to install the ring-shaped sealing strip 22 and to install the aforementioned sunroof glass assembly 31 on the inner side of the ring-shaped sealing strip 22.

[0056] The mounting frame 21 also has a support plate 213 arranged in a ring around the mounting window 212. The support plate 213 has an L-shaped vertical cross-section and extends downward from the outer end of the mounting plate 211. Figure 7 , Figure 10 .

[0057] When the mounting frame 21 is assembled onto the roof panel 1, the mounting window 212 corresponds to the position of the skylight 11, such that the edge of the roof panel 1 near the skylight 11 is on the upper surface of the mounting plate 211. Figure 10 Then, the upper surface of the mounting plate 211 is bonded and fixed to the lower surface of the roof panel 1.

[0058] To improve bonding stability, the upper surface of the mounting plate 211 has several grooves 214 arranged in a ring around the mounting window, such as... Figure 10 When adhesive is applied to the upper surface of the mounting plate 211, the grooves 214 arranged in sequence are filled with adhesive, reducing the phenomenon of adhesive being squeezed out from the upper surface of the mounting plate 211 when it is attached to the roof panel 1, thereby improving the bonding effect.

[0059] To facilitate better assembly and positioning, a raised ring 215 extends upward from the inner end of the mounting plate 211, forming a ring around the mounting window 212. Figure 10 The mounting plate 211 is assembled with the roof panel 1 by inserting a raised ring 215 into the sunroof 11, thereby positioning the sunroof 11 on the roof panel 1. The height of the raised ring 215 is approximately equal to the thickness of the roof panel 1, ensuring that after the roof panel 1 and the mounting plate 211 are assembled, the upper surface of the roof panel 1 and the upper surface of the raised ring 215 are flush, thus improving the sealing effect between the two and the sealing strip 22.

[0060] To improve the assembly effect between the sealing strip 22 and the mounting frame 21, an assembly ring 216 is extended downward from the inner end of the mounting plate 211 and distributed in a ring around the mounting window. This ring is used to achieve the snap-fit ​​assembly between the sealing strip 22 and the lower part of the mounting plate 211, which facilitates the disassembly and assembly of the sealing strip 22 and the mounting frame 21 while ensuring assembly stability.

[0061] like Figure 10 The aforementioned support plate 213 includes a horizontal portion 217 and a vertical portion 218 connected to form an L-shape. The horizontal portion 217 is connected to the mounting plate 211 via the vertical portion 218, forming a Z-shaped structure with the mounting plate 211, the vertical portion 218, and the horizontal portion 217. The horizontal portion 217 is used for assembly with the support beam 23, allowing the support beam 23 to be suspended below the horizontal portion 217. When the mounting plate 211 is assembled with the roof panel 1, this L-shaped design causes the horizontal portion 217 to sink a certain height relative to the mounting plate 211; on the one hand, it allows a gap space to be formed between the horizontal portion 217 and the roof panel 1. When several first nuts 219 (such as...) are pre-pressed into the upper surface of the horizontal portion 217... Figure 7 The support plate 213 has five first nuts 219 on each of its left and right sides. When it is assembled with the support beam 23, the gap space can provide space for the first nuts 219. On the other hand, it can also shorten the distance between the support plate 213 and the sunroof frame assembly 32 located below the support beam 23, so that the space position of the sunroof frame assembly 32 can avoid the modification frame and prevent installation obstacles.

[0062] Moreover, the strength of the mounting frame 21 is higher than that of the roof panel 1. After bonding, the roof panel 1 and the mounting frame 21 are clamped and fixed by strong clamps until the adhesive cures. Taking advantage of the fact that the strength of the mounting frame 21 is higher than that of the roof panel 1, the curvature of the roof panel 1 is corrected by the mounting frame 21, thereby making the curvature of the roof panel 1 highly consistent with the curvature of the mounting plate 211 and the sunroof glass. With the function of correcting the curvature of the roof, the mounting frame 21 can be adapted to various models with different curvatures, and also helps to prevent water leakage from the modified sunroof.

[0063] Meanwhile, the mounting frame 21 is made of aluminum alloy. Its structure is manufactured using a process of first extruding a profile with a regular cross-sectional shape, and then bending it to form a ring. This allows the mounting frame 21 to form a ring-shaped structural component with a regular cross-section, resulting in high strength and lightweight product characteristics. Furthermore, compared to sheet metal stamping, this profile bending method significantly reduces mold costs and achieves products with higher dimensional accuracy and structural strength. Moreover, the ring-shaped design of the mounting frame 21 increases the bonding area with the roof panel 1, improving connection stability and enhancing the overall strength of the mounting frame 21.

[0064] Regarding sealing strip 22:

[0065] like Figure 3 , Figure 4 , Figure 10 The outer side of the annular sealing strip 22 is used to assemble with the inner side of the annular mounting plate 211, and the inner side is used to install the sunroof glass assembly 31. This allows the sealing strip 22 to construct an installation scheme for the sunroof glass assembly 31 to be installed in the mounting window 212 at the inner end of the mounting frame 21. The position of the sealing strip 22 on the inner side of the mounting frame 21 also ensures that the sunroof glass assembly 31 does not protrude from the roof panel 1, maintaining the overall flatness of the roof appearance.

[0066] The inner side of the annular sealing strip 22 has an annularly distributed compression cavity 221, such as... Figure 8 , Figure 10 The sealing strip 22 can be squeezed and deformed from the inside. That is, when the sunroof glass assembly is installed on the inside of the sealing strip 22, the squeezed and deformed sealing strip 22 makes the sealing strip 22 fit tightly with the sunroof glass assembly 31, resulting in a good sealing effect.

[0067] A ring-shaped hook portion 222 extends outward from the lower outer part of the annular sealing strip 22, as shown in the image. Figure 8 , Figure 10 The hook 222 and the outer side of the sealing strip 22 form an upward-opening slot 223, which is used for the mounting ring 216 of the mounting plate 211 to engage and assemble the two.

[0068] An annular covering portion 224 extends outward from the upper outer part of the annular sealing strip 22, as shown in the image. Figure 8 , Figure 10 When the mounting frame 21 is assembled with the roof panel 1 using the raised ring 215, and the sealing strip 22 is fastened into the mounting ring 216 using the slot 223, the cover 224 will cover the raised ring 215 and the edge 12 of the roof panel 1 near the sunroof 11. Then, glue is injected between the cover 224 and the roof panel 1, so that the cover 224 is bonded to the upper surface of the roof panel 1. In this way, the cover 224 can cover the cut edge of the sunroof 11, improving the aesthetics, and also providing a leak-proof effect. At the same time, the length of the cover 224 is designed to be 10-15mm, which accounts for about 1 / 3-1 / 2 of the length of the mounting plate 211. The extended design of the cover 224 allows for a secure bond between the cover 224 and the roof panel 1, and avoids the swaying and abnormal noise that often occurs when the cover 224 is too short to bond properly.

[0069] Regarding load-bearing beams:

[0070] A strip-shaped load-bearing beam 23 is installed on each of the left and right sides of the annular mounting frame 21, such as... Figure 4 , Figure 6 , Figure 9 , Figure 10Of course, in other embodiments, the load-bearing beams 23' installed on the left and right sides of the annular mounting frame 21 can also be several block structures, such as... Figure 15 , Figure 16 Five block-shaped support beams 23' are installed on each side as shown. In this way, after the sunroof glass assembly 31 is fitted with the sealing strip 22, the left and right sides of the sunroof frame assembly 32 can be assembled with the support beams 23 and 23' respectively. With the help of the support beams 23 and 23' and the mounting frame 21, it can be indirectly assembled to the roof panel 1, thereby ensuring the stability of the sunroof glass assembly 31 and the sunroof sunshade assembly 33.

[0071] Meanwhile, the load-bearing beams 23 and 23' are installed on the transverse portion 217 of the load-bearing plate 213 and do not directly contact the roof panel 1, thus reducing the need for modification work on the vehicle's original roof panel 1.

[0072] Furthermore, the load-bearing beams 23 and 23' are positioned on the left and right sides of the mounting frame 21. On one hand, this allows for the use of side-mounted suspension to provide support strength for the sunroof frame assembly 32. On the other hand, the strip-shaped design of the load-bearing beam 23 or the block-shaped design of the load-bearing beam 23', compared to a ring-shaped design, provides more space for installing various sunroof frame assemblies with different shapes below the mounting frame. Figure 3 As shown, the front and rear sides and the left and right sides of this sunroof frame component 32 are at different heights (the gap between the left and right sides where the sunroof rail is located and the mounting frame is large, while the gap between the front and rear sides where the sunshade frame is located and the mounting frame is small). If a ring-shaped beam is used, the front and rear sides of the sunroof frame component will become an obstacle when the left and right sides of the sunroof frame component are assembled with the beam.

[0073] Of course, in other embodiments, for certain sunroof assemblies, if the front and rear sides of the sunroof frame assembly do not pose an installation obstacle, the load-bearing beam can also be designed as a ring.

[0074] The strip structure of load-bearing beam 23 is hollow, such as... Figure 9The rectangular hollow strip structure shown, with the hollow design of the supporting beam 23, allows the bottom surface of this beam (i.e., the mounting surface connecting to the sunroof frame assembly) to sink further to a certain height, thereby meeting the spacing requirements between the left and right sides of the sunroof frame assembly and the sunroof glass assembly. In other words, there is a fixed spacing between the sunroof frame assembly and the sunroof glass assembly, and the left and right sides and front and rear sides of the sunroof frame assembly are at different heights. The modified frame 2 sinks once through the annular horizontal part 217 to approach the mounting surface of the sunroof frame assembly 32, and this sinking does not cause the horizontal part 217 to obstruct the front and rear sides of the sunroof frame assembly. Then, the hollow design of the strip-shaped supporting beam 23 allows for a second sinking to connect with the mounting surface of the sunroof frame assembly 32. That is, the modified frame 2 uses the horizontal part 217 and the supporting beam 23 to sink in two stages, simultaneously ensuring installation on the left and right sides of the sunroof frame assembly 32 without obstructing the front and rear sides.

[0075] Several first mounting holes 231 are evenly opened on the load-bearing beam 23, such as Figure 9 The five first mounting holes 231 are shown. The supporting beam 23 is placed below the horizontal part 217 of the mounting frame 21, so that the first mounting holes 231 correspond to the positions of the first nuts 219. The screws are placed in the first mounting holes 231 and assembled with the first nuts 219, thereby realizing the installation of the supporting beam 23 on the horizontal part 217. At the same time, the screws are hidden in the hollow cavity of the supporting beam 23, so as not to cause any obstruction to the assembly of the bottom surface of the supporting beam 23 and the sunroof frame assembly 32.

[0076] Several second nuts 232 are pre-pressed evenly into the hollow cavity of the load-bearing beam 23, such as... Figure 9 The four second nuts 232 shown are used to assemble the sunroof frame assembly 32 onto the load-bearing beams 23 on the left and right sides respectively by screwing through the mounting holes on the sunroof frame assembly 32 and assembling with the second nuts 232.

[0077] Thus, the hollow design of the load-bearing beam 23 serves another purpose: to provide space for the screws used to assemble the load-bearing beam 23 and the transverse portion 217, as well as for the second nut 232 used to assemble the load-bearing beam 23 and the sunroof frame assembly 32.

[0078] Furthermore, in order to facilitate the rapid assembly and positioning of the load-bearing beam 23 with the transverse part 217 and the sunroof frame assembly 32, a positioning post 233 is installed on the load-bearing beam 23, and corresponding positioning holes 220 are opened in the transverse part 217 and the sunroof frame assembly 32 respectively. The positioning post 233 is inserted into the positioning hole 220 to quickly position the assembly position of the load-bearing beam 23 with the transverse part 217 and the sunroof frame assembly 32.

[0079] Regarding the assembly of a modified sunroof product using the modified frame 2 of Example 1:

[0080] The sunroof should be modified, such as Figure 3 The modified frame 2 and the sunroof assembly 3, which is a prior art, are included. The sunroof assembly 3 includes a sunroof glass component 31 and a sunroof frame component 32. The sunroof glass component 31 is installed inside the sealing strip 22. The sunroof glass component 31 will squeeze the compression cavity 221 inside the sealing strip 22, thereby achieving a tight fit between the two and improving the sealing assembly effect. The left and right sides of the sunroof frame component 32 correspond to the left and right side load-bearing beams 23 on the modified frame 2. The positioning post 233 of the load-bearing beam 23 is inserted into the positioning hole of the sunroof frame component 32. Several screws are used to pass through the assembly hole and assemble with the second nut 232 inside the load-bearing beam 23 to realize the assembly of the sunroof frame component 32 and the load-bearing frame 23.

[0081] Regarding the modified frame, Example 2 is given here:

[0082] The modified frame 2 of this embodiment includes an annular mounting frame 21' and an annular sealing strip 22, but does not have the load-bearing beam 23 component of embodiment 1.

[0083] like Figure 11 In this embodiment, the mounting frame 21' has the same structure and function as in Embodiment 1, including an annular mounting plate 211, a mounting window 212 enclosed on the inner side of the mounting plate 211, a groove 214 on the upper surface of the mounting plate 211, a raised ring 215 at the upper inner end of the mounting plate 211, and an assembly ring 216 at the lower inner end of the mounting plate 211. Furthermore, the structure, function, and assembly relationship of the sealing strip 22 with the mounting plate 211 in this embodiment are the same as in Embodiment 1.

[0084] The special feature of the mounting frame 21' in this embodiment is that the outer ends of the left and right sides of the mounting plate 211 are formed with bearing plates 213' of L-shaped vertical cross-section, such as... Figure 11 The support plate 213' includes a horizontal plate 41 and a vertical plate 42 connected to form an L-shape. The horizontal plate 41 is connected to the mounting plate 211 through the vertical plate 42. The horizontal plate 41 is used to assemble with the sunroof frame assembly 32, so that the sunroof frame assembly 32 is suspended below the horizontal plate 41.

[0085] Compared to Embodiment 1, this embodiment uses an extended vertical plate 42 to replace the two-stage combined sinking height of the horizontal part 217 and the supporting beam 23 in Embodiment 1. The sinking height is completed in one go, allowing the horizontal plate 41 to directly connect with the mounting surface of the sunroof frame assembly 32. At the same time, the supporting plates 213' are only set on the left and right sides of the corresponding mounting position of the sunroof frame assembly 32, instead of using a ring structure. This avoids the assembly obstacles that the horizontal plate 41 would pose to the sunroof frame assembly 32 in the case of a ring structure.

[0086] Of course, in other embodiments, vertical members 51 with only vertical portions can also be formed on the outer ends of the front and rear sides of the mounting plate 211, such as... Figure 12 Alternatively, an L-shaped component 52 may be formed, although its vertical cross-section is also L-shaped, but the height of its vertical portion is significantly smaller than that of the vertical plate 42 in Embodiment 2, such as... Figure 13 , Figure 14 As shown, it is acceptable as long as it does not obstruct the installation of the sunroof frame assembly 32.

[0087] In this embodiment, several mounting nuts 243 are pre-pressed into the horizontal plate 41, and corresponding mounting holes are formed on the sunroof frame assembly 32. The left and right sides of the sunroof frame assembly 32 are placed below the horizontal plate, and screws are used to assemble them with the mounting nuts 243 through the mounting holes, thereby realizing the direct installation of the sunroof frame assembly 32 onto the horizontal plate 41 of the mounting frame 21'. Moreover, the design of the vertical plate 42 also provides space for pre-pressing the mounting nuts 243 into the upper surface of the horizontal plate 41.

[0088] Regarding the assembly of a modified sunroof product using the modified frame of Example 2:

[0089] The modified sunroof includes the aforementioned modified frame 2 and the existing sunroof assembly 3. The sunroof assembly 3 includes a sunroof glass assembly 31 and a sunroof frame assembly 32. The sunroof glass assembly 31 is installed inside the sealing strip 22. The sunroof glass assembly 32 will squeeze the compression cavity 221 inside the sealing strip 22, thereby achieving a tight fit between the two and improving the sealing assembly effect. The left and right sides of the sunroof frame assembly 32 correspond to the left and right support plates 213' on the modified frame 2. Several screws are used to pass through the mounting holes and assemble with the mounting nuts 243 on the support plates 213' to realize the assembly of the sunroof frame assembly 32 and the mounting frame 21'.
