[0055] To install a sunroof on a car that originally did not have one, the roof panel 1 was first cut to create a sunroof window 11, as shown below. Figure 1 As shown, then the sunroof product assembled using the modified frame 2 and the sunroof glass 3 or the sunroof assembly 4 provided in the following embodiment is installed on the sunroof 11 (e.g., Figure 3 or Figure 13 This allows for the installation of a sunroof at sunroof 11 by modifying frame 2, thus achieving the goal of adding a modified sunroof to the roof. Figure 2 As shown.

[0056] Regarding the modified frame, Example 1 is given here:

[0057] Reference Figures 5 to 10 The modified frame 2 includes an annular upper frame 21, an annular lower frame 22, an annular waterproof sealing strip 23, and an annular shock-absorbing sealing strip 24.

[0058] It should be noted that the modified frame in this embodiment is described in an open-ended way, including two frame components, upper frame 21 and lower frame 22, without excluding the possibility of other frame components. However, in other embodiments, the modified frame can also adopt a closed design, that is, it can also meet the frame construction requirements by consisting only of upper frame 21 and lower frame 22. Here, frame components refer to the parts that directly participate in the construction of the frame; the aforementioned additional components such as waterproof sealing strip 23 and shock-absorbing sealing strip 24 are not considered frame components.

[0059] Regarding the upper frame 21:

[0060] The upper frame 21, on the one hand, is assembled with the lower frame 22 and cooperates to clamp the window edge 12 of the roof panel 1 (the window edge 12 is the part of the roof panel 1 near the sunroof 11, such as...). Figure 1 This allows the modified frame 2 to be installed in the skylight 11; on the other hand, it is used to install the shock-absorbing sealing strip 24 and fix the skylight glass 3.

[0061] like Figure 10The upper frame 21 has a first outer bottom plate 211, a first inner bottom plate 212, a first vertical plate 213, and a first clamping plate 214. The first vertical plate 213 connects the first outer bottom plate 211 and the first clamping plate 214 into a whole by connecting the bottom end of the first outer bottom plate 211 to the inner end of the first clamping plate 214 and the top end of the first vertical plate 213. The first inner bottom plate 212 is connected to the first outer bottom plate 211 to form a bottom plate. The first vertical plate 213 is used to divide the inner and outer sides. The part located inside the first vertical plate 213 is called the first inner bottom plate 212, and the part located outside the first vertical plate 213 is called the first outer bottom plate 211.

[0062] The first clamping plate 214 is used to cooperate with the lower frame 22 to clamp the window edge 12 of the roof panel 1; the first outer bottom plate 211 has a flat vertical section and is used to assemble with the lower frame 22 to realize the assembly of the upper frame 21 and the lower frame 22; the first outer bottom plate 211 is located below the first clamping plate 214 and there is a certain gap between the two formed by the first vertical plate 213. The first clamping plate 214, the first vertical plate 213, and the first outer bottom plate 211 together enclose a first installation space 215 with an opening facing outward, so that the first outer bottom plate 211 and the lower frame 22 can be assembled with screws. The first installation space 215 has the characteristics of an open outer side and a certain height cavity, which provides working space for screw installation and lowers the assembly height position of the first outer bottom plate 211 used to assemble the lower frame 22.

[0063] When the modified frame 2 is used to assemble a fixed sunroof with the existing sunroof glass 3: a groove 2121 is formed on the upper surface of the first inner bottom plate 212, and a retaining strip 241 is attached to the shock-absorbing seal 24. The shock-absorbing seal 24 is installed on the upper surface of the first inner bottom plate 212 of the upper frame 21 by the snap-fit ​​assembly of the retaining strip 241 and the groove 2121. The edge 31 of the sunroof glass 3 is placed on the shock-absorbing seal 24 to achieve a shock absorption effect. Adhesive is filled between the edge 31 and the inner side of the first vertical plate 213 to achieve adhesive assembly of the sunroof glass 3 and the upper frame 21.

[0064] Regarding box 22:

[0065] The lower frame 22 serves two purposes: firstly, it is assembled with the upper frame 21 and used to clamp the window edge 12 of the roof panel 1 near the sunroof, thereby enabling the modified frame 2 to be installed in the sunroof 11; secondly, it can be used as a load-bearing component for installing the sunroof sunshade, enabling the fixed sunroof to be used in conjunction with the installation of the sunroof sunshade.

[0066] like Figure 10The lower frame 22 has an annular second outer bottom plate 221, an annular second inner bottom plate 222, an annular second vertical plate 223, and an annular second clamping plate 224. The second vertical plate 223 connects the second inner bottom plate 222 and the second clamping plate 224 into a whole by connecting the bottom end to the outer end of the second inner bottom plate 222 and the top end to the inner end of the second clamping plate 224. The second inner bottom plate 222 and the second outer bottom plate 221 are connected to form a bottom plate. The inner and outer sides are divided by the second vertical plate 223. The part located inside the second vertical plate 223 is called the second inner bottom plate 222, and the part located outside the second vertical plate 223 is called the second outer bottom plate 221.

[0067] In other embodiments, the first inner bottom plate 212 may be offset from the first outer bottom plate 211 by a certain height, so that the first inner bottom plate 212 is connected to the side of the first vertical plate 213 away from the first outer bottom plate 211; similarly, the second inner bottom plate 222 may be offset from the second outer bottom plate 221 by a certain height, so that the second outer bottom plate 221 is connected to the side of the second vertical plate 223 away from the second inner bottom plate 222.

[0068] The position of the second clamping plate 224 corresponds to the position of the first clamping plate 214 of the upper frame 21, such as Figure 10 The second clamping plate 224 is located below the first clamping plate 214, and there is a certain gap between the two. This gap is the clamping space 25 formed between the first clamping plate 214 and the second clamping plate 224 for clamping the roof panel 1. The clamping space 25 is open to the outside of the modified frame 2 so that the modified frame 2 clamps the window edge 12 of the roof panel 1, thereby allowing the modified frame 2 to be installed inside the sunroof 11, thereby reducing the area occupied by the modified frame 2 above the roof panel 1.

[0069] To prevent water leakage after the modified frame 2 is installed on the roof panel 1, a ring-shaped waterproof sealing strip 23 should be installed at the contact surface between the modified frame 2 and the upper surface of the roof panel 1; such as Figure 10 Alternatively, a waterproof sealing strip 23 can be installed on the lower surface of the first clamping plate 214 of the upper frame; in other embodiments, the waterproof sealing strip 23 can also be installed on the window edge portion 12 on the upper surface of the roof panel 1 as needed.

[0070] The position of the second inner bottom plate 222 corresponds to the position of the first outer bottom plate 211 of the upper frame 21, such as Figure 10 The second inner bottom plate 222 is located below the first outer bottom plate 211. The second inner bottom plate 222 and the first outer bottom plate 211 are assembled together using screws to achieve the assembly of the lower frame 22 and the upper frame 21.

[0071] There is a certain gap between the second outer bottom plate 221 and the second clamping plate 224 formed by the second vertical plate 223. The outer side of the second vertical plate 223 and the upper surface of the second outer bottom plate 221 enclose a second installation space 225 with an open outer side. The second installation space 225 can be used to assemble the sunshade when the second outer bottom plate 221 is used as a load-bearing part. For example, the track of the sunshade can be assembled with the second outer bottom plate 221 using screws, which also reduces the height of the second outer bottom plate 221.

[0072] In this embodiment, as Figure 10 The second clamping plate 224 is formed by extending outward from the top of the second vertical plate 223, such that the top of the second vertical plate 223 is connected to the inner end of the second clamping plate 224. Figure 11 As shown, the second mounting space 225 is only open on the outer side. However, in other embodiments, the shape of the second clamping plate can also be formed by extending inward from the top of the second vertical plate, so that the top of the second vertical plate is connected to the outer end of the second clamping plate, and the top side of the second mounting space is also open. Alternatively, the second clamping plate and the second vertical plate can form a T-shaped structure, that is, the top of the second vertical plate is connected to the middle of the second horizontal plate, and the second mounting space is only open on the outer side. The length of the second clamping plate and the connection position with the second vertical plate are only required to ensure that they can form a stable clamping effect on the roof panel with the first clamping plate.

[0073] Regarding the modified frame, Example 2 is given here:

[0074] like Figure 11 The similarities between this embodiment 2 and embodiment 1 are as follows: the first clamping plate 214, the first vertical plate 213, and the first outer bottom plate 211 have an upper frame 21, and the second clamping plate 224, the second vertical plate 223, the second inner bottom plate 222, and the second outer bottom plate 221 have a lower frame 22. The first clamping plate 214 and the second clamping plate 224 are positioned to clamp the window edge 12 of the roof panel 1. The second inner bottom plate 222 and the first outer bottom plate 211 are positioned to be assembled using screws.

[0075] like Figure 11 The difference between this embodiment 2 and embodiment 1 is that it does not have the first inner bottom plate 212 of the upper frame 21 and the shock-absorbing sealing strip 24 installed on the first inner bottom plate 212 as in embodiment 1, and it has an additional third vertical plate 216 for connecting the outer end of the first outer bottom plate 211 and the first clamping plate 214; specifically:

[0076] The modified frame 2 of this embodiment 2 is used to assemble the sunroof assembly 4, which is a prior art technology (such as...). Figure 13The diagram shows a sunroof assembly 4, which is an operable sunroof that can be used to control the opening and closing of the sunroof. It includes a sunroof glass assembly 41, a sunroof frame assembly 42, and a sunshade assembly 43. Other models without a sunshade assembly are also available in the prior art. In this type of product, there is a fixed gap between the sunroof frame assembly 42 and the sunroof glass assembly 41, which in turn requires a predetermined height position for the load-bearing components of the modification frame. An annular sunroof sealing strip 26 is installed on the inner side of the first vertical plate 213 by adhesive bonding. The sunroof glass assembly 41 is inserted into the sunroof sealing strip 26. The sunroof frame assembly 42 is assembled with the second outer bottom plate 221 of the lower frame 22, which serves as the load-bearing component. The sunshade assembly 43 is installed on the sunroof frame assembly 42, thereby enabling the modification frame 2 to be installed in the sunroof window 11, and the sunroof assembly 4 to be installed on the modification frame 2, thus achieving the purpose of adding a sunroof to the sunroof window 11.

[0077] Meanwhile, in this embodiment 2, the outer end of the first outer bottom plate 211 is connected to the lower surface of the first clamping plate 214 by a third vertical plate 216 to increase the support effect and make the first installation space 215 a sealed space in the vertical section.

[0078] Regarding the modified frame, Example 3 is given here:

[0079] like Figure 12 The similarities between this embodiment 3 and embodiment 1 are as follows: the first clamping plate 214, the first vertical plate 213, and the first outer bottom plate 211 have an upper frame 21, and the second clamping plate 224, the second vertical plate 223, and the second inner bottom plate 222 have a lower frame 22. The first clamping plate 214 and the second clamping plate 224 are positioned to clamp the window edge 12 of the roof panel 1. The second inner bottom plate 222 and the first outer bottom plate 211 are positioned to be assembled using screws.

[0080] like Figure 12 The difference between this embodiment 3 and embodiment 1 is that it does not have the first inner bottom plate 212 of the upper frame 21 and the shock-absorbing sealing strip 24 installed on the first inner bottom plate 212 as in embodiment 1, nor does it have the second outer bottom plate 221 of the lower frame 22 as in embodiment 1; specifically:

[0081] like Figure 12 , Figure 13 In this embodiment 3, the modified frame 2 is also used to assemble the sunroof assembly 4, which is a prior art technology. An annular sunroof sealing strip 26 is installed on the inner side of the first vertical plate 213 by adhesive bonding. The sunroof glass assembly 41 is inserted into the sunroof sealing strip 26. The sunroof frame assembly 42 is not connected to the modified frame 2 (the modified frame 2 does not have a second outer bottom plate 221 as a load-bearing component). Instead, it is fixed by connecting the sunroof frame assembly 42 to the vehicle body through the hooks 44 on both sides.

[0082] Regarding the skylight, Example 4 is given here:

[0083] A fixed sunroof can be assembled using the modified frame 2 of Example 1, such as... Figure 3 The sunroof includes the modified frame 2 of Embodiment 1 and the sunroof glass 3, which is a prior art feature. The sunroof glass 3 is placed on the shock-absorbing sealing strip 24 of the modified frame 2, and the sunroof glass 3 is bonded to the upper frame 21, as shown below. Figure 10 .

[0084] Moreover, such as Figure 3 , Figure 4 As needed, a sunroof sunshade 32 can be installed on the second outer bottom plate 221. When the sunshade is open, light can shine into the vehicle, and when the sunshade is closed, it can provide sun protection.

[0085] Regarding skylights, Example 5 is given here:

[0086] An operable sunroof is assembled using the modified frame 2 of Embodiment 2. This sunroof includes the modified frame 2 of Embodiment 2 and a sunroof assembly 4 with operable glass, which is a prior art material. The sunroof glass assembly 41 is installed within the sunroof sealing strip 26. Figure 12 This allows the sunroof frame assembly 42 to be mounted on the second outer bottom plate 221, thus adding a sunroof to the sunroof opening 11. The operable sunroof assembly can selectively open the sunroof as needed to promote airflow. Furthermore, a sunshade assembly 43 can be installed on the sunroof frame assembly 42 as required. When the sunshade is open, light can enter the vehicle; when closed, it provides sun protection.

[0087] Regarding skylights, Example 6 is given here:

[0088] An operable sunroof can be assembled using the modified frame 2 of Example 3, such as... Figure 13 The sunroof includes the modified frame 2 of Embodiment 3 and the sunroof assembly 4, which is a prior art technology. The sunroof glass assembly 41 is installed inside the sunroof sealing strip 26, and the sunroof frame assembly 42 is mounted on the vehicle body using hooks 44 on both sides, without being connected to the modified frame 2. This achieves the addition of a sunroof to the sunroof opening 11, and the operable sunroof assembly can selectively open the sunroof as needed to promote air circulation. Moreover, a sunshade assembly 43 can be installed on the sunroof frame assembly 42 as needed. When the sunshade is open, light can shine into the vehicle interior, and when the sunshade is closed, it can provide a sunshade effect.
