[0058] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0059] The car sunroof sunshade includes components such as the sunshade frame and roller assembly. The frame is on which a curtain that moves back and forth to open and close can be installed. The sunshade is then installed on the car sunroof as an aftermarket addition, allowing for the installation of a sunshade on a car that does not come with one, and providing sun protection as needed.

[0060] like Figure 1 , Figure 8 The sunshade frame includes a flat interior panel 3, two slide rails 1, and a base 4. The two slide rails 1 are respectively mounted on the flat interior panel 3 on the left and right sides, and the slide rails 1 allow the curtain fabric of the sunshade to move back and forth along the slide rails 1. The base 4 is mounted on the slide rails 1, and a rotatable roller assembly 2 for rolling up and unrolling the curtain fabric is rotatably mounted between the two bases 4 at the same end of the slide rails 1. Figure 1 (Not shown in the text), the scroll assembly 2 is prior art and will not be described in detail here.

[0061] like Figure 1 , Figure 8 The interior panel 3 has a window 31 in the middle. When the sunshade is installed at the sunroof, the window 31 is located at the sunroof. Normally, people inside the car cannot see the roller assembly 2 when they look up through the window 31. When the curtain of the sunshade is unfolded and covers the window 31, it is used for sunshade. When the curtain is rolled up and does not cover the window 31, sunlight can shine into the car. The window 31 is a design that traditional car sunroof sunshade interior panels also have, and will not be described in detail.

[0062] The difference is that the flat interior panel 3 here is assembled from two flat panels 32 on the left and right. In other embodiments, it can also be composed of a single flat panel. The upper and lower surfaces of the flat interior panel 3 are both flat structures. The development and manufacturing costs of this flat interior panel 3 are lower, resulting in better economic benefits. At the same time, compared with interior panels with curved structures, it can save more height space occupied by the sunshade when it is installed in the vehicle.

[0063] The aforementioned bases 4 are stacked on top of the corresponding slide rails 1, and the bases 4 are provided with rotation holes 43 for mounting the rotatable scroll assembly 2 (e.g., Figure 2 , Figure 3 ,like Figure 9 , Figure 10 ,Figure 11 This design, utilizing the base 4 positioned on top of the slide rail 1, raises the height of the rotating hole 43 on the base 4. This better leverages the conditions of the aftermarket installation scenario, ensuring the rotating hole 43 is higher than the top surface of the slide rail 1. It also maintains the planar structure of the interior trim panel 3, creating a larger gap between the rotating hole 43 on the base 4 and the interior trim panel 3. This provides ample space for the roll-up thickness of the curtain fabric after the roller assembly 2 is installed on the base 4, making it particularly suitable for scenarios where single-opening sunshades have a large roll-up thickness. This design abandons the traditional approach of mounting the base on the side or end of the slide rail, and the design of recessing one end of the interior trim panel corresponding to the roller assembly to create a curved structure in order to provide sufficient space for the roller assembly with a large roll-up thickness.

[0064] Of course, in other embodiments, a rotating groove can be used instead of the rotating hole 43. The rotating hole 43 and the rotating groove are just some specific implementations used herein to describe the mounting part for mounting the reel assembly 2. In addition, the rotating holes 43 can be designed as two vertically arranged side by side, so that the base 4 can better match the reel assemblies 2 with different winding thicknesses, thereby improving the applicability of the base 4.

[0065] The aforementioned sunshade frame can be used for assembling car sunshades that can be opened manually or electrically. The following explanation uses a motor-driven car sunshade as an example.

[0066] When the above-mentioned frame is used for motorized sunshades, the conventional driving method using the electric drive device 5 is as follows: Figure 1 , Figure 8 For example, there is motor 51 ( Figure 1 (Not shown in the text) The flexible shaft drives the curtain to move back and forth along the slide rail 1 through meshing transmission, and the flexible shaft is equipped with a cable tube 52 to ensure smooth movement of the flexible shaft. This electric drive device 5 is prior art and will not be described in detail.

[0067] To ensure the stability of the conduit 52 that connects to the end of the slide rail 1, a conduit connector 6 is provided for the aforementioned frame, such as... Figure 2 , Figure 3 ,like Figure 9 , Figure 10 , Figure 12 It is used to position the end of the conduit 52 corresponding to the slide rail 1.

[0068] There are multiple ways to assemble the base 4, slide rail 1, and conduit connector 6. This article mainly describes the following two embodiments:

[0069] Example 1:

[0070] like Figures 1 to 3The base 4 is stacked on top of the slide rail 1 and does not extend beyond the end of the slide rail along its length, so that the rotating hole 43 corresponds to the top of the slide rail 1 but does not extend beyond the end of the slide rail 1, while the conduit connector 6 is positioned on the outer side of the corresponding end of the slide rail 1 (i.e., Figure 2 , Figure 3 (The front side of the slide rail end is roughly distributed along the length of the slide rail), so that the base 4 will not extend to the position above the corresponding conduit connector 6.

[0071] A mounting foot 61 extends from one side of the conduit connector 6, such as Figure 4 The bottom surface of the mounting foot 61 is flush with the bottom surface of the conduit connector 6. The mounting foot 61 is inserted into the end of the slide rail 1 to connect the two. The slide rail 1 has a cavity for the mounting foot 61 to be inserted. Thanks to the design feature of the mounting foot 61 being flush with the bottom surface of the conduit connector 6 and the insertion method with the slide rail 1, the conduit connector 6, after being installed on the slide rail 1, will not exceed the overall height of the slide rail 1, thus saving the overall height occupied by the frame. This also achieves the connection of the conduit connector 6 to the slide rail 1, enabling assembly. Furthermore, after assembly by inserting the mounting foot 61 into the end of the slide rail 1, the conduit connector 6 is located on the outer front side of the end of the slide rail 1.

[0072] like Figure 4 The mounting feet 61 of the conduit connector 6 have clearance grooves 611 formed to avoid the W-shaped transition wall 13 on the slide rail 1. When the slide rail 1 is assembled with the mounting feet 61, the W-shaped transition wall 13 at the end of the slide rail 1 is placed in the clearance grooves 611, and the flexible shaft can move within the conduit 52 and the slide rail 1. At the same time, to facilitate the assembly of the mounting feet 61 and the slide rail 1, the flat plate 11 on the bottom surface of the end of the slide rail 1 corresponding to the mounting feet 61 of the conduit connector 6 can be removed, that is, the bottom surface of the slide rail 1 at the position corresponding to the mounting feet 61 of the conduit connector 6 does not have a flat plate 11.

[0073] By using the installation method of the mounting feet 61 of the base 4, slide rail 1, and conduit connector 6, not only can the three be connected, but they are also stacked and distributed, which fully guarantees the thickness space of the curtain roll-up and reduces the overall height of the frame. This is conducive to adapting to the diversity of aftermarket space for sunshades brought about by different car interior spaces.

[0074] At the same time, such as Figure 4 , Figure 7 The conduit connector 6 is fitted with a top cover 62. Corresponding grooves 63 are formed on both the conduit connector 6 and the top cover 62. After assembly, the corresponding grooves 63 of the conduit connector 6 and the top cover 62 together form a wire hole 64. This wire hole 64 allows the conduit 52 to pass through, enabling radial positioning of the conduit 52 when the top cover 62 is fixed to the conduit connector 6. After the conduit 52 is installed, a flexible shaft passing through the conduit 52 can be smoothly inserted into the slide rail 1 to drive the curtain fabric to move.

[0075] Furthermore, to ensure the axial positioning effect of the conduit 52, a positioning ring is formed on the outer wall of the conduit 52 near its end, and a positioning groove 631 is formed on the conduit connector 6. When the conduit 52 is installed in the conduit hole 64, the positioning ring is placed in the positioning groove 631. Of course, the positioning ring here is just one manifestation of the positioning protrusion formed on the outer wall of the conduit 52; positioning protrusions or the like can also be used instead of the positioning ring. Moreover, the positions of the positioning protrusion and the positioning groove can be interchanged, that is, a positioning groove is set on the conduit, and a corresponding positioning protrusion is set on the conduit connector. These alternative methods are all conventional means and will not be described in detail.

[0076] Example 2:

[0077] like Figures 8 to 12 The base 4 is stacked on top of the slide rail 1. The rotating hole 43 on the base 4 extends beyond the end of the slide rail 1 along its length, meaning the rotating hole 43 is not located above the slide rail 1. The conduit connector 6 is positioned on the outer side of the corresponding end of the slide rail 1 (i.e., Figure 2 The front side of the slide rail end is roughly distributed along the length of the slide rail, and the location of the rotating hole 43 on the base 4 corresponds to the position above the conduit connector 6.

[0078] Regarding the specific positional relationship of the base 4 stacked on top of the slide rail 1, the difference between this embodiment 2 and embodiment 1 is that, as Figure 3 and Figure 11 The positions of the rotating holes 43 on the base 4 and the front end of the slide rail 1 differ in the two embodiments. In embodiment 2, the rotating holes 43 are located closer to the front edge of the flat interior panel 3 compared to embodiment 1. Consequently, after the roller assembly 2 is installed, it is closer to the front edge of the flat interior panel 3. This allows for the window 31 to be widened along the length of the slide rail 1. In other words, the flat interior panel 3 assembled in embodiment 2 has a wider window 31 than the flat interior panel 3 assembled in embodiment 1. In scenarios where the sunroof model is the same and the aftermarket space is limited, a wider window 31 provides a wider field of vision when the sunshade is open. In other words, embodiment 2 not only expands the winding space of the roller assembly 2 by stacking the base 4 on the slide rail 1, but also widens the window 31 of the flat interior panel 3 by changing the assembly relationship between the base 4 and the slide rail 1.

[0079] It needs to be emphasized that: Figure 2 , Figure 3 Although in embodiment 1, neither the rotating hole 43 of the base 4 nor the front end of the base 4 extends beyond the front end of the slide rail 1; as Figure 10 , Figure 11In Embodiment 2, the rotating hole 43 of the base 4 and the front end of the base 4 both extend beyond the front end of the slide rail 1. However, Embodiment 2, compared to Embodiment 1, embodies the design concept of moving the rotating hole 43 of the base 4 forward along the length direction of the slide rail 1 to facilitate the widening of the window 31. Therefore, in other embodiments, the design scheme of moving the rotating hole 43 of the base 4 forward without extending beyond the front end of the slide rail 1 and the front end of the base 4 extending outward from the front end of the slide rail 1 is still within the protection scope of the design concept in this paper.

[0080] like Figure 14 The conduit connector 6 has an upward-opening groove 63, and the bottom of the end of the base 4 extending beyond the slide rail 1 has a downward-opening groove 63. Figure 18 After the conduit connector 6 and the base 4 are assembled, the corresponding wire grooves 63 of the two will surround and form a wire hole 64, such as Figure 10 , Figure 16 The wire hole 64 allows the conduit 52 to pass through, enabling radial positioning of the conduit 52 when the base 4 is assembled with the conduit connector 6. After the conduit 52 is installed, the flexible shaft passing through the conduit 52 can be smoothly inserted into the slide rail 1 to drive the curtain fabric to move.

[0081] In this embodiment 2, the form of the wire hole 64 is different from that in embodiment 1. The end of the base 4 that extends beyond the end of the slide rail 1 also serves as the "top cover" in embodiment 1, thus constructing a special wire positioning mechanism for positioning the wire tube.

[0082] A mounting foot 61 extends from one side of the conduit connector 6, such as Figure 17 , Figure 13 , Figure 14 The bottom surface of the mounting foot 61 is flush with the bottom surface of the conduit connector 6. The mounting foot 61 is inserted into the end of the slide rail 1. The slide rail 1 has a cavity for the mounting foot 61 to be inserted. Thanks to the design feature of the mounting foot 61 being flush with the bottom surface of the conduit connector 6 and the insertion method with the slide rail 1, the conduit connector 6, after being installed on the slide rail 1, will not exceed the overall height of the slide rail 1, thus saving the overall height occupied by the frame. This also allows the conduit connector 6 to be connected to the slide rail 1, achieving assembly. Furthermore, after assembly by inserting the mounting foot 61 into the end of the slide rail 1, the conduit connector 6 is located on the outer front side of the end of the slide rail 1.

[0083] like Figure 18 The bottom of the end of the base 4 that extends beyond the end of the slide rail 1 extends downward to form a slot 47 for engaging the conduit connector 6. The conduit connector 6 engages with the bottom of the base 4 to achieve assembly. In other embodiments, other snap-fit ​​installation methods can also be used for the conduit connector and the bottom of the base.

[0084] To accurately determine the assembly positions of base 4, conduit connector 6, and slide rail 1, refer toFigure 13 , Figure 14 A positioning block 65 is formed on the conduit connector 6. The mounting foot 61 is inserted into the slide rail 1, and the front end face of the slide rail 1 abuts against the side of the positioning block 65 to achieve positioning. Figure 18 The slot 47 of the base 4 corresponds to the side of the slide rail 1, which is the positioning surface 49 of the base 4. When the base 4 is installed on the slide rail 1, the front end of the slide rail 1 abuts against the positioning surface 49 of the slot 47. Alternatively, a rib 48 can be formed at the bottom of the end of the base 4 that extends beyond the end of the slide rail 1, so that the side of the rib 48 corresponding to the side of the slide rail 1 constitutes the positioning surface 49 of the base 4. When the base 4 is installed on the slide rail 1, the front end of the slide rail 1 abuts against the positioning surface 49 of the rib 48, thus achieving the positioning effect.

[0085] For the conduit 52 used for installation in the wire hole 64, its end is enlarged (enlarging means increasing the diameter of the inner hole at the end; this enlarging operation is a prior art technique). The enlarged end of the conduit is called the enlarged end, and the enlarged portion is called the enlarged part 521. Figure 13 After the enlarged hole 521 is enlarged, its inner diameter is naturally larger than the inner diameter of other parts of the conduit. In this way, during the reciprocating movement of the flexible shaft, the end face of the enlarged hole 521 will not touch the flexible shaft, thus avoiding damage to the flexible shaft by the end face of the conduit 52.

[0086] like Figure 13 , Figure 14 When the front end face of the slide rail 1 abuts against the side of the positioning block 65, a gap space 66 is formed between the front end face of the slide rail 1 and the side of the wire groove 63 on the wire conduit connector 6; the wire conduit 52 is installed in the wire hole 64, and the enlarged hole portion 521 is placed in the gap space 66; at the same time, the bottom of the base 4 also has a receiving groove 46 corresponding to the position of the gap space 66 for accommodating the enlarged hole portion 521, such as Figure 17 , Figure 18 .

[0087] like Figure 17 , Figure 14 The mounting feet 61 of the conduit connector 6 have a clearance groove 611 for avoiding the W-shaped transition wall 13 on the slide rail 1. This clearance groove 611 communicates with the gap space 66 and the wire groove 63. When the slide rail 1 and the conduit connector 6 are assembled, the W-shaped transition wall 13 at the end of the slide rail 1 is placed in the clearance groove 611, and the flexible shaft can move within the conduit 52 and the slide rail 1. At the same time, to facilitate the assembly of the conduit connector 6 and the slide rail 1, the flat plate 11 on the bottom surface of the end of the slide rail 1 corresponding to the mounting feet 61 of the conduit connector 6 can be removed, that is, the bottom surface of the end of the slide rail 1 at the position corresponding to the mounting feet 61 of the conduit connector 6 does not have a flat plate 11.

[0088] Furthermore, to ensure the axial positioning effect of the conduit 52, a positioning ring is formed on the outer wall of the conduit 52 near its end, and a positioning groove 631 is formed on the conduit connector 6, such as... Figure 17 , Figure 13 Meanwhile, the base 4 also has a positioning groove 631 corresponding to the positioning groove 631 of the conduit connector 6, used to accommodate the positioning ring; when the conduit 52 is installed in the wire hole 64, the positioning ring is inserted into the positioning groove 631. Of course, the positioning ring here is just one form of positioning protrusion formed on the outer wall of the conduit, and positioning protrusions or the like can also be used instead of the positioning ring; and the positions of the positioning protrusion and the positioning groove can also be interchanged, that is, a positioning groove is set on the conduit, and a corresponding positioning protrusion is set on the conduit connector; these alternative methods are all conventional means and will not be described in detail.

[0089] The two embodiments described above provide a scheme in which the base 4 for mounting the roller assembly 2 and the conduit connector 6 for mounting the conduit 52 are placed at the same end of the slide rail 1, thereby distributing the roller assembly 2 and the motor 51 at the same end of the sunshade. However, in other embodiments, the base for mounting the roller assembly and the conduit connector can be placed at opposite ends of the slide rail, so that the roller assembly and the motor are distributed at opposite ends of the sunshade, with other components adjusted as needed.

[0090] Here is one possible structural design for slide rail 1:

[0091] like Figure 19 The bottom surface of the slide rail 1 is composed of a flat plate 11, thus making the bottom surface of the slide rail 1 flat. This facilitates the adhesion of the slide rail 1 to the upper surface of the flat interior panel 6 for fixed installation. Here, the bottom surface of the slide rail does not constitute part of the interior panel, but is installed as a whole on the upper surface of the interior panel. When passengers look up, they can see the lower surface of the flat interior panel and will not see the slide rail.

[0092] In addition to the flat plate 11, the slide rail 1 also has a U-shaped wall 12 with an overall inverted U-shaped cross-section extending upward from the upper surface of the flat plate 11. The flat plate 11 and the U-shaped wall 12 together enclose a first closed cavity 121 with an overall square cross-section. The top surface of the U-shaped wall 12 is recessed downward to form a transition wall 13 with a W-shaped cross-section. By forming it by the downward recess, the overall height can be reduced.

[0093] The first end face (i.e., the left end face of the left side portion 131) and the second end face (i.e., the middle end face) of the transition wall 13 extend upwards respectively to form a first inclined wall 133 and a second inclined wall 134. After the top of the first inclined wall 133 intersects with the top of the second inclined wall 134, a transverse wall 135 continues to extend. The first inclined wall 133, the second inclined wall 134, and the left side portion 131 of the W-shaped transition wall 13 enclose a second closed cavity 136. The first inclined wall 133 extends a protrusion 137 toward the second closed cavity 136. The protrusion 137 and the left side portion 131 of the transition wall 13 enclose an arc-shaped first mounting cavity 138 at the bottom of the second closed cavity 136. The first mounting cavity 138 can be used to accommodate the flexible shaft and allow the flexible shaft to move within the cavity. Moreover, the inclined design of the first inclined wall 133 and the second inclined wall 134 can reduce the overall height of the slide rail 1.

[0094] The third end face of the other end of the transition wall 13 (i.e., the right end face of the right side portion 132) extends upward into a bent wall 14. This bent wall 14 is located below the aforementioned transverse wall 135 and forms a gap cavity 141 with an opening facing the inside of the slide rail 1 between it and the transverse wall 135. This gap cavity 141 communicates with the second mounting cavity 139 and allows the end of the pull rod (or the slider installed at the end) used to move the curtain to move to move within it. It is a conventional method to set a pull rod at the moving end of the curtain in the roller assembly 2 (the end where the curtain is connected to the roller is called the winding end, and the moving end is opposite to the winding end), and for the end of the pull rod to move within the slide rail. This will not be described in detail here.

[0095] Simultaneously, the second inclined wall 134, together with the right side portion 132 of the W-shaped transition wall 13 and the bent wall 14, encloses an arc-shaped second mounting cavity 139. This second mounting cavity 139 can be used to accommodate the flexible shaft and allow it to move within the cavity. The aforementioned first mounting cavity 138 and second mounting cavity 139, through their arc-shaped design, radially constrain the circular cross-section sidewalls of the flexible shaft to prevent bending, while also providing a guiding function for movement.

[0096] Meanwhile, a third mounting cavity 15 with an opening facing the inside of the slide rail 1 is formed between the top surface on the right side of the bent wall 14 and the top surface on the right side of the U-shaped wall 12 (i.e., the top surface on the right side of the transition wall). The third mounting cavity 15 allows the side edge strip of the curtain to move inside it, thus placing the side edge of the curtain inside the slide rail 1 and avoiding the leakage caused by the lateral gap between the curtain and the slide rail 1.

[0097] The top surface of the right side of the U-shaped wall 12, the bent wall 14, and the transverse wall 135 are arranged vertically in sequence at intervals. Based on the concave formation of the W-shaped transition wall and the inclined design of the first inclined wall 133 and the second inclined wall 134, which reduces the height of the transverse wall 135, the top surface of the right side of the U-shaped wall 12 is designed to be lower than the top surface of the left side (i.e., the top surface located on the left side of the transition wall). This reduces the height of the bent wall 14. While fully ensuring the usable space height of the gap cavity 141 and the third mounting cavity 15, it further reduces the overall height of the slide rail 1, saving interior space.

[0098] Furthermore, the inner side of the bending wall 14 extends downward to form a hook 142, which bends toward the third mounting cavity 15. The hook 142 can be used to form a lateral constraint on the edge strip to prevent the side of the curtain from falling laterally off the slide rail 1, and can also improve the lateral tension of the curtain.

[0099] Even better, the aforementioned U-shaped wall 12 is located on one side of the plate 11, and a bent portion 16 extends upward from the other side of the upper surface of the plate 11. The bent portion 16 and the upper surface of the plate 11 enclose a fourth mounting cavity 161 with an opening facing the inside of the slide rail 1. The fourth mounting cavity 161 can be used to install an ambient light.

[0100] Furthermore, the bent portion 16, together with the U-shaped wall 12 and the flat plate 11, forms a fifth mounting cavity 17 with an upward opening. This fifth mounting cavity 17 can be used to install the support leg of the base 4 at the end of the fifth mounting cavity to realize the assembly of the slide rail 1 and the base 4, and can be used to install ambient lights, etc. in the middle of the fifth mounting cavity.

[0101] The aforementioned first mounting cavity 138, second mounting cavity 139, third mounting cavity 15, gap cavity 141, fourth mounting cavity 161, and fifth mounting cavity 17 are integrated onto a single slide rail 1, enabling the slide rail 1 to perform multiple functions.

[0102] It should be noted that the usage of the first mounting cavity 138, the second mounting cavity 139, the third mounting cavity 15, the gap cavity 141, the fourth mounting cavity 161, and the fifth mounting cavity 17 in other embodiments should not be limited to the usage of this embodiment, as long as it is a reasonable assembly and usage method that can be implemented by those skilled in the art.

[0103] Here is one possible structural design for base 4:

[0104] like Figure 4 , Figure 5 Figure 6 , Figure 15 , Figure 17The outer wall of the base 4 has a connecting part 41, which is used to install the connecting part 41 on the top surface of the left side of the U-shaped wall 12 of the slide rail 1 by screws, thereby realizing the fixed connection between the base 4 and the slide rail 1; moreover, the bottom surface of the base 4 has a relief groove 42 corresponding to the top outline of the slide rail 1 (i.e., the first inclined wall 133 and the transverse wall 135), thereby reducing the overall height of the base 4 after it is stacked on top of the slide rail 1; one end of the inner wall of the base 4 has a rotating hole 43, which is used to rotatably assemble with the roller assembly 2; a connecting post 44 is formed in the middle of the inner wall of the base 4, and a pressure strip is installed between the connecting posts 44 of the two bases at the same end. The pressure strip is used to press on the curtain and has the effect of preventing the curtain from sticking up.

[0105] Furthermore, a guide seat 45 is formed on the lower part of the inner side wall of the base 4. An installation notch 101 is opened on the inner side of the end of the slide rail 1 where the base 4 is installed. The guide seat 45 is placed in the installation notch 101. An installation leg 451 is formed at the end of the guide seat 45. The installation leg 451 is inserted into the fifth installation cavity 17 of the slide rail 1 to realize the assembly of the base 4 and the slide rail 1. At the same time, an inclined guide part 452 with a certain slope is formed at the end of the guide seat 45. After the base 4 and the slide rail 1 are assembled, the inclined guide part 452 corresponds to the top surface of the right side of the U-shaped wall 12 of the slide rail 1, which facilitates the smooth introduction of the curtain into the third installation cavity 15 of the slide rail 1 and prevents the curtain from being scratched and damaged by the end face of the slide rail when it enters the slide rail 1.

[0106] By using the installation method of the base 4, slide rail 1, and cable connector 6 provided above, the three components are stacked and assembled, which fully guarantees the thickness space of the curtain roll-up and reduces the overall height of the frame. This is conducive to adapting to the diversity of aftermarket space for sunshades brought about by different vehicle interior spaces.

[0107] Furthermore, fasteners are used to better ensure the stable installation of the base 4, slide rail 1, and conduit connector 6. For example, screws are used. Mounting holes are provided on the connecting part 41 of the base 4, the top surface of the U-shaped wall 12 of the slide rail 1, and the mounting feet 61 of the conduit connector 6. The three are connected and secured by mounting screws (not shown in the figure). It is particularly important to note that after installing the fasteners (such as screws), the exposed part of the fasteners must not exceed the top surface of the base 4 or the bottom surface of the slide rail 1. The top surface of the base 4 is taken as the top surface of the entire frame. That is, the top surfaces of other components in the frame will not be higher than the top surface of the base 4. The fasteners do not exceed the top surface of the base. This ensures that when the sunshade frame is added behind it, the fasteners will not accidentally scratch the sunroof glass or other interior trim. The fasteners do not exceed the bottom surface of the slide rail 1. This ensures the flat design of the bottom surface of the slide rail 1, which is convenient for bonding to the flat interior trim panel 3.

[0108] Meanwhile, the frame also includes a front beam 7 bonded to the upper surface of the flat interior panel 3. The front beam 7 has a flat bottom surface. The front beam 7 is located at the front end of the two side slide rails 1 (i.e., one end of the mounting base), and the bottom surface of the front beam 7 is flush with the bottom surface of the slide rail 1. The conduit connector 6 is installed on the upper surface of the front beam 7.

[0109] Meanwhile, the aforementioned frame also includes a rear beam 8 bonded to the upper surface of the flat interior panel 3. The rear beam 8 also has a flat bottom surface and is connected to the rear end of the side rails 1. The bottom surface of the rear beam 8 is flush with the bottom surface of the rails 1. By utilizing the design that the bottom surfaces of the front beam 7, the rails 1, and the rear beam 8 are all flat, it is easy to bond the three components together to the upper surface of the flat interior panel 3.

[0110] For interior trim panels with different widths on both sides, such as Figure 1 , Figure 8 The front side of the interior panel is wider than the rear side, so the front beam 7 corresponding to the front side is a longer beam, so that the two ends of the beam extend beyond the two side slide rails 1 respectively. This helps to enhance the strength of the interior panel 3 where the extended part is located and reduce the bending damage of the interior panel 3 during transportation.

[0111] Meanwhile, mounting plates 9 are provided on both the front beam 7 and the rear beam 8. By inserting the mounting plates 9 into the gap between the sunroof and the interior trim, the sunshade can be retrofitted to the sunroof. If this sunshade product or frame is intended for the aftermarket, installation methods that require removal or damage to the original interior trim should be avoided as much as possible.
