[0047] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention 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 only used to explain the present invention and are not used to limit the present invention.

[0048] An automotive sunshade curtain for a skylight includes components such as a sunshade curtain frame and a reel assembly. The frame is provided for mounting a curtain cloth thereon that can reciprocate to open and close. The entire sunshade curtain is then installed on the automotive skylight in a retrofitting manner, adding a sunshade curtain to an after - sales automotive vehicle without a sunshade curtain, and playing a sunshading role according to requirements.

[0049] Such as Figure 1 、 Figure 8 , the sunshade curtain frame includes components such as a planar interior trim panel 3, two slide rails 1, a base 4, etc.; the two slide rails 1 are respectively installed on the planar interior trim panel 3 on the left and right sides, and the slide rails 1 allow the curtain cloth of the sunshade curtain to reciprocate along the slide rails 1; the base 4 is installed on the slide rails 1, and a rotatable reel assembly 2 ( Figure 1 omitted and not shown in the figure) for winding and unwinding the curtain cloth of the sunshade curtain is rotatably installed between the two bases 4 at the same end of the slide rails 1. Here, the reel assembly 2 is prior art knowledge and will not be elaborated.

[0050] Such as Figure 1 、 Figure 8, the middle part of the flat interior trim panel 3 has a window 31. After the sunshade is integrally installed at the automotive skylight, the position of this window 31 corresponds to the automotive skylight. Under normal circumstances, when a person inside the vehicle looks up through this window 31, the reel assembly 2 cannot be seen. When the curtain cloth of the sunshade unfolds to cover this window 31, it is used for sunshading. When the curtain cloth is wound up and does not cover this window 31, sunlight can shine into the vehicle interior. This window 31 is a design that traditional automotive skylight sunshades' interior trim panels all have, and will not be elaborated further.

[0051] The difference is that the flat interior trim panel 3 here is assembled by two left and right flat panels 32. In other embodiments, it can also be composed of one flat panel. Moreover, both the upper surface and the lower surface of the flat interior trim panel 3 are flat structures. Using this flat interior trim panel 3 has lower development costs and manufacturing costs, and has better economic benefits. At the same time, compared with the interior trim panel with a curved surface structure, it can also save more height space occupied when the sunshade is retrofitted inside the vehicle.

[0052] The above-mentioned bases 4 are respectively stacked on the tops of the corresponding slide rails 1, and the bases 4 are provided with rotation holes 43 for installing the rotatable reel assembly 2 (such as Figure 2 , Figure 3 , such as Figure 9 , Figure 10 , Figure 11 ). In this way, by using the design of placing the base 4 on the top of the slide rail 1, the height of the rotation hole 43 of the base 4 is raised. Preferably, the conditions of the retrofitted interior of the vehicle are fully utilized, so that the position of the rotation hole 43 is higher than the top surface of the slide rail 1, taking into account the protection of the flat structure design of the flat interior trim panel 3, so that a larger spacing is formed between the rotation hole 43 of the base 4 and the flat interior trim panel 3, which is used to provide sufficient winding thickness space for winding the curtain cloth when the reel assembly 2 is installed on the base 4, and is particularly suitable for the scenario where the winding thickness is relatively large after the single-opening sunshade is wound up. Abandon the design idea in the traditional frame that the base is installed on the side or end face of the slide rail, and a curved surface structure is formed by concaving one end of the interior trim panel corresponding to the reel assembly in order to make sufficient space for the reel assembly with a relatively large winding thickness after winding.

[0053] Of course, for the rotation hole 43, in other embodiments, the rotation hole 43 can be replaced by a rotation groove. The rotation hole 43 and the rotation groove are just some specific implementation means used in this article to describe the installation part for installing the reel assembly 2. In addition, the rotation hole 43 can also be designed into two vertically arranged side by side, so that the base 4 can better match the reel assemblies 2 with different winding thicknesses and improve the applicability of the base 4.

[0054] The above-mentioned sunshade frame can be used for assembling automotive skylight sunshades that can be opened manually or electrically. Below, an example of an electric automotive skylight sunshade driven by a motor to open will be elaborated.

[0055] When the above frame is used for an electric sunshade, the conventional driving method using the electric driving device 5 is as follows: Figure 1 , Figure 8 , for example, there is a motor 51 ( Figure 1 The flexible shaft drives the curtain to move back and forth along the slide rail 1 through meshing transmission, and a wire tube 52 is configured for the flexible shaft to ensure smooth movement of the flexible shaft. The electric drive device 5 belongs to the prior art and is not described in detail.

[0056] In order to ensure the stability of the wire tube 52 connected to the end of the slide rail 1, a wire tube connecting seat 6 is configured for the frame. Figure 2 , Figure 3 ,like Figure 9 , Figure 10 , Figure 12 , used to position the end of the wire tube 52 corresponding to the slide rail 1.

[0057] There are multiple implementation schemes for the assembly relationship between the base 4, the slide rail 1, and the wire tube connecting seat 6. This article mainly describes the following two embodiments:

[0058] Embodiment 1:

[0059] like Figures 1 to 3 The base 4 is stacked and installed on the top of the slide rail 1 and does not exceed the end of the slide rail along the length direction of the slide rail 1, so that the rotation hole 43 corresponds to the top of the slide rail 1 and does not exceed the end of the slide rail 1, and the wire tube connection seat 6 is placed at the outer position corresponding to the end of the slide rail 1 (that is, Figure 2 , Figure 3 The front side of the end of the slide rail is roughly distributed along the length direction of the slide rail), so that the base 4 will not extend to the corresponding upper position of the wire tube connecting seat 6.

[0060] A mounting foot 61 extends from one side of the wire tube connection seat 6. Figure 4 The bottom surface of the mounting foot 61 is flush with the bottom surface of the wire tube connection seat 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. At the same time, with the design feature that the mounting foot 61 is flush with the bottom surface of the wire tube connection seat 6 and the plugging method with the slide rail 1, the wire tube connection seat 6 will not exceed the overall height of the slide rail 1 after being installed on the slide rail 1, thereby saving the height occupied by the entire frame, and realizing the connection of the wire tube connection seat 6 to the slide rail 1, so as to realize the assembly of the two. After the mounting foot 61 is inserted into the end of the slide rail 1 for assembly, the wire tube connection seat 6 is located at the outer front side of the end of the slide rail 1.

[0061] like Figure 4, an avoidance groove 611 for avoiding the W-shaped transition wall 13 on the slide rail 1 is formed on the mounting foot 61 of the wire tube connecting seat 6. When the slide rail 1 is assembled with the mounting foot 61, the W-shaped transition wall 13 at the end of the slide rail 1 is placed in the avoidance groove 611, and the flexible shaft can move within the wire tube 52 and the slide rail 1. Meanwhile, to facilitate the assembly of the mounting foot 61 and the slide rail 1, the flat plate 11 at the bottom surface of the end of the slide rail 1 corresponding to the mounting foot 61 of the wire tube connecting seat 6 can be removed, that is, the flat plate 11 is not provided at the position on the bottom surface of the end of the slide rail 1 corresponding to the mounting foot 61 of the wire tube connecting seat 6.

[0062] Through the installation methods of the base 4, the slide rail 1, and the mounting foot 61 of the wire tube connecting seat 6, not only can the connection of the three be realized, but also a state of superposition and distribution of the three is presented, which fully guarantees the thickness space for curtain cloth winding and reduces the overall height of the frame, being beneficial to adapting to the diversity of the rear-mounted space of the sunshade curtain brought by the interior spaces of different vehicle models.

[0063] Meanwhile, as Figure 4 , Figure 7 , a top cover 62 is installed on the wire tube connecting seat 6, corresponding wire grooves 63 are respectively formed on the wire tube connecting seat 6 and the top cover 62, and after the wire tube connecting seat 6 and the top cover 62 are assembled, the corresponding wire grooves 63 of the two enclose to form a wire hole 64, and the wire tube 52 can pass through the wire hole 64, so as to realize the radial positioning of the wire tube 52 when the top cover 62 is fixed to the wire tube connecting seat 6. After the wire tube 52 is installed, the flexible shaft passing through the wire tube 52 can be smoothly placed into the slide rail 1 to drive the curtain cloth to move.

[0064] Moreover, in order to ensure the axial positioning effect of the wire tube 52, a positioning ring is formed at a position close to the end on the outer side wall of the wire tube 52, and a positioning groove 631 is formed on the wire tube connecting seat 6. When the wire tube 52 is installed in the wire hole 64, the positioning ring is placed in the positioning groove 631. Of course, the positioning ring here is just a manifestation form of forming a positioning protrusion on the outer side wall of the wire tube 52, and the positioning protrusion can also be replaced by a positioning bump, etc.; and the forming positions of the positioning protrusion and the positioning groove can also be interchanged, that is, a positioning groove is provided on the wire tube and a corresponding positioning protrusion is provided on the wire tube connecting seat; these alternative methods are all conventional means and will not be elaborated.

[0065] Embodiment 2:

[0066] As Figures 8 to 12 , the base 4 is stacked and installed on the top of the slide rail 1, and the part of the rotation hole 43 on the base 4 extends beyond the end of the slide rail 1 along the length direction of the slide rail 1, that is, the rotation hole 43 does not correspond to being located above the slide rail 1, while the wire tube connecting seat 6 is placed at an outer position corresponding to the end of the slide rail 1 (that is, Figure 2 roughly at the front side of the end of the slide rail distributed along the length direction of the slide rail), and the part of the rotation hole 43 on the base 4 corresponds to the position above the wire tube connecting seat 6.

[0067] Regarding the specific positional relationship of the base 4 stacked and installed on the 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 parts where the rotation holes 43 on the base 4 are located relative to the front end of the front side of the slide rail 1 are different. In Embodiment 2, the part where the rotation hole 43 is located is closer to the front side edge of the flat interior trim panel 3 compared to Embodiment 1. Furthermore, after the reel assembly 2 is installed, the reel assembly 2 is closer to the front side edge of the flat interior trim panel 3. In this way, room can be left for widening the window 31 along the length direction of the slide rail 1. That is, the flat interior trim panel 3 adopting the assembly scheme of Embodiment 2 has a wider window 31 than the flat interior trim panel 3 adopting the assembly scheme of Embodiment 1. In the scenario where the automotive sunroof models are the same and the space for post-installation inside the vehicle is limited, having a wider window 31 means having a broader view after the sunshade curtain is opened. That is to say, this Embodiment 2 can not only utilize the stacking of the base 4 on the slide rail 1 to expand the winding space of the reel assembly 2, but also can achieve the effect of widening the window 31 of the flat interior trim panel 3 by changing the assembly relationship between the base 4 and the slide rail 1.

[0068] It should be emphasized that: as Figure 2 、 Figure 3 , although neither the rotation hole 43 of the base 4 nor the front end of the base 4 in Embodiment 1 extends beyond the front end of the slide rail 1; as Figure 10 、 Figure 11 , both the rotation hole 43 of the base 4 and the front end of the base 4 in Embodiment 2 extend beyond the front end of the slide rail 1, but Embodiment 2 reflects the design concept of moving the rotation hole 43 of the base 4 forward along the length direction of the slide rail 1 to facilitate the widening of the window 31 compared to Embodiment 1. Then, in other embodiments, the design scheme of moving the rotation 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 beyond the front end of the slide rail 1 still falls within the protection scope of the design concept herein.

[0069] As Figure 14 , a wire groove 63 with an upward opening is formed on the wire pipe connection seat 6, and a wire groove 63 with a downward opening is formed at the bottom of the end of the base 4 extending beyond the end of the slide rail 1. As Figure 18 , after the wire pipe connection seat 6 and the base 4 are assembled, the corresponding wire grooves 63 of the two enclose to form a wire hole 64. As Figure 10 、 Figure 16 , the wire hole 64 can be passed through by the wire pipe 52 so that when the base 4 and the wire pipe connection seat 6 are assembled, radial positioning of the wire pipe 52 can be achieved. After the wire pipe 52 is installed, the flexible shaft passing through the wire pipe 52 can be smoothly placed into the slide rail 1 to drive the curtain cloth to move.

[0070] In Embodiment 2, compared with Embodiment 1, in the form of the wire hole 64, one end of the base 4 extending beyond the end of the slide rail 1 also serves as the "upper cover" in Embodiment 1, constructing a special wire pipe positioning mechanism for positioning the wire pipe.

[0071] One side of the wire pipe connecting seat 6 extends to form a mounting foot 61. As Figure 17 , Figure 13 , Figure 14 , the bottom surface of the mounting foot 61 is flush with the bottom surface of the wire pipe connecting seat 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 insert. At the same time, by virtue of the design feature that the bottom surface of the mounting foot 61 is flush with the bottom surface of the wire pipe connecting seat 6 and the insertion method with the slide rail 1, after the wire pipe connecting seat 6 is installed on the slide rail 1, it will not exceed the overall height of the slide rail 1, thus saving the height occupied by the overall frame and realizing the connection of the wire pipe connecting seat 6 to the slide rail 1 and the assembly of the two. And after the mounting foot 61 is inserted into the end of the slide rail 1 for assembly, the wire pipe connecting seat 6 is located at the front side outside the end of the slide rail 1.

[0072] As Figure 18 , a card slot 47 for clamping the wire pipe connecting seat 6 is formed by the bottom of one end of the base 4 extending downward beyond the end of the slide rail 1. The wire pipe connecting seat 6 is clamped at the bottom of the base 4 to realize the assembly of the two. In other embodiments, other specific implementation means of clamping and installing the wire pipe connecting seat and the bottom of this end of the base can also be adopted.

[0073] To accurately determine the assembly positions of the base 4, the wire pipe connecting seat 6 and the slide rail 1, referring to Figure 13 , Figure 14 , a positioning block 65 is formed on the wire pipe connecting seat 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 face of the positioning block 65 to realize positioning. As Figure 18 , the side face of the above card slot 47 of the base 4 corresponding to one side of the slide rail 1 is the positioning surface 49 of the base 4. When the base 4 is installed on the slide rail 1, the front end face of the slide rail 1 abuts against the positioning surface 49 of the card slot 47; of course, a rib plate 48 can also be formed at the bottom of one end of the base 4 extending beyond the end of the slide rail 1, and the side face of the rib plate 48 corresponding to one 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 face of the slide rail 1 abuts against the positioning surface 49 of the rib plate 48 to achieve the positioning effect.

[0074] For the wire pipe 52 to be installed in the wire hole 64, the end of it is subjected to reaming treatment of the inner hole (the reaming treatment is to enlarge the diameter of the inner hole at the end, and the implementation means of this reaming operation is the prior art). The end of the wire pipe after reaming is called the reamed end, and the reamed part is called the reamed portion 521. As Figure 13, after the reaming process, the inner diameter of the reaming portion 521 is naturally larger than that of other parts of the wire tube. In this way, during the reciprocating movement of the flexible shaft, the end face of the reaming portion 521 will not touch the flexible shaft, avoiding scratching the flexible shaft by the end face of the wire tube 52.

[0075] Such as Figure 13 , Figure 14 , when the front end face of the slide rail 1 abuts against the side face of the positioning block 65, a gap space 66 is formed between the front end face of the slide rail 1 and the side face of the wire groove 63 on the wire tube connecting seat 6; the wire tube 52 is installed in the wire hole 64, and the reaming portion 521 is placed in the gap space 66; at the same time, a receiving groove 46 corresponding to the position of the gap space 66 and used for receiving the reaming portion 521 is also formed at the bottom of the base 4, such as Figure 17 , Figure 18 .

[0076] Such as Figure 17 , Figure 14 , an avoidance groove 611 for avoiding the W-shaped transition wall 13 on the slide rail 1 is formed on the mounting foot 61 of the wire tube connecting seat 6, and the avoidance groove 611 communicates with the gap space 66 and the wire groove 63. When the slide rail 1 and the wire tube connecting seat 6 are assembled, the W-shaped transition wall 13 at the end of the slide rail 1 is placed in the avoidance groove 611, and the flexible shaft can move in the wire tube 52 and the slide rail 1. At the same time, in order to facilitate the assembly of the wire tube connecting seat 6 and the slide rail 1, the flat plate 11 at the bottom surface of the end corresponding to the mounting foot 61 of the wire tube connecting seat 6 on the slide rail 1 can be removed, that is, the bottom surface of this end of the slide rail 1 does not have the flat plate 11 corresponding to the position of the mounting foot 61 of the wire tube connecting seat 6.

[0077] Moreover, in order to ensure the axial positioning effect of the wire tube 52, a positioning ring is formed at a position near the end of the outer side wall of the wire tube 52, and a positioning groove 631 is formed on the wire tube connecting seat 6, such as Figure 17 , Figure 13 , at the same time, a positioning groove 631 corresponding to the position of the positioning groove 631 on the wire tube connecting seat 6 and used for receiving the positioning ring is also formed on the base 4; when the wire tube 52 is installed in the wire hole 64, the positioning ring is snapped into the positioning groove 631. Of course, the positioning ring here is only a manifestation form of forming a positioning protrusion on the outer side wall of the wire tube, and the positioning protrusion can also be replaced by a positioning bump, etc.; and the forming positions of the positioning protrusion and the positioning groove can also be interchanged, that is, a positioning groove is provided on the wire tube, and a corresponding positioning protrusion is provided on the wire tube connecting seat; these alternative methods are all conventional means and will not be elaborated.

[0078] The above two embodiments provide a solution where the base 4 for installing the reel assembly 2 and the conduit connection base 6 for installing the conduit 52 are placed at the same end of the slide rail 1, so that the reel assembly 2 and the motor 51 are distributed at the same end of the sunshade. However, in other embodiments, the base for installing the reel assembly and the conduit connection base can also be placed at both ends of the slide rail, so that the reel assembly and the motor are distributed at both ends of the sunshade, and other components are adjusted accordingly.

[0079] Here is a possible structural solution for the slide rail 1:

[0080] As Figure 19 , the bottom surface of the slide rail 1 is composed of a flat plate 11. In this way, the bottom surface of the slide rail 1 is a plane, which is convenient for bonding the slide rail 1 to the upper surface of the flat interior trim panel 6 for fixed installation. The bottom surface of the slide rail here does not form part of the interior trim panel, but is integrally installed on the upper surface of the interior trim panel. The occupants in the vehicle can see the lower surface of the flat interior trim panel when looking up, but cannot see the slide rail.

[0081] In addition to the flat plate 11, the upper surface of the flat plate 11 extends upward to form a U-shaped wall 12 with an overall inverted U-shaped cross-section. The flat plate 11 and the U-shaped wall 12 enclose a first closed cavity 121 with an overall square cross-section. The middle part of the top surface of the U-shaped wall 12 is recessed downward to form a transition wall 13 with a W-shaped cross-section, which can be formed by downward recessing to reduce the overall height.

[0082] The first end face (i.e., the left end face of the left side part 131) and the middle second end face (i.e., the middle end face) of the transition wall 13 respectively extend obliquely upward to correspond to form a first inclined wall 133 and a second inclined wall 134. The top ends of the first inclined wall 133 and the second inclined wall 134 intersect and then continue to extend to form a transverse wall 135. The first inclined wall 133, the second inclined wall 134 and the left side part 131 of the W-shaped transition wall 13 enclose a second closed cavity 136, and the first inclined wall 133 extends a convex part 137 toward the second closed cavity 136. The convex part 137 and the left side part 131 of the transition wall 13 enclose an arc-shaped first installation cavity 138 at the lower part of the second closed cavity 136. This first installation cavity 138 can be used to accommodate the flexible shaft and allow the flexible shaft to move in this 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.

[0083] At the other end of the transition wall 13, a third end face (i.e., the right end face of the right side portion 132) extends upward to form a bent wall 14. The bent wall 14 is relatively located below the transverse wall 135, and a clearance cavity 141 with an opening facing the inside of the slide rail 1 is formed between the bent wall 14 and the transverse wall 135. The clearance cavity 141 communicates with the second installation cavity 139 and can be used for the end portion of a pull rod (or a slider installed at the end portion) for pulling the curtain to move therein. The arrangement of the pull rod at the moving end of the curtain in the reel assembly 2 (the end where the curtain is connected to the reel is called the winding end, and the moving end is opposite to the winding end) and the movement of the end portion of the pull rod in the slide rail are both conventional means and will not be elaborated here.

[0084] Meanwhile, the second inclined wall 134, the right side portion 132 of the W-shaped transition wall 13, and the bent wall 14 enclose an arc-shaped second installation cavity 139, which can be used to accommodate a flexible shaft and allow the flexible shaft to move therein. The above-mentioned first installation cavity 138 and second installation cavity 139 can radially constrain the side wall of the flexible shaft with a circular cross-section by means of an arc design to prevent the flexible shaft from bending, and at the same time have a movement guiding function.

[0085] Meanwhile, a third installation cavity 15 with an opening facing the inside of the slide rail 1 is enclosed between the bent wall 14 and the top surface on the right side of the U-shaped wall 12 (i.e., the top surface located on the right side of the transition wall). The third installation cavity 15 can be used for the folded edge strip on the side of the curtain to move therein, that is, to place the side of the curtain in the slide rail 1, avoiding the occurrence of a lateral gap between the curtain and the slide rail 1 and preventing leakage.

[0086] The top surface on the right side of the U-shaped wall 12, the bent wall 14, and the transverse wall 135 are arranged vertically at intervals in sequence. On the basis that the inner concave formation of the above-mentioned W-shaped transition wall and the inclined design of the first inclined wall 133 and the second inclined wall 134 reduce the height of the transverse wall 135, the top surface on the right side of the U-shaped wall 12 is designed to be lower than the top surface on the left side (i.e., the top surface located on the left side of the transition wall), so as to reduce the height of the bent wall 14. On the premise of fully ensuring the height of the use space of the clearance cavity 141 and the third installation cavity 15, the overall height of the slide rail 1 is further reduced, saving the occupied space in the vehicle.

[0087] Moreover, the inner side edge of the bent wall 14 extends downward to form a hook portion 142, which bends towards the inside of the third installation cavity 15. The hook portion 142 can be used to form a lateral constraint on the folded edge strip to prevent the side of the curtain from laterally falling off the slide rail 1 and can also improve the lateral tension of the curtain.

[0088] Preferably, the above-mentioned U-shaped wall 12 is located on one side of the flat plate 11, and a bent portion 16 extends upward on the other side of the upper surface of the flat plate 11. A fourth installation cavity 161 with an opening facing the inside of the slide rail 1 is enclosed between the bent portion 16 and the upper surface of the flat plate 11, and the fourth installation cavity 161 can be used to install an ambient light.

[0089] Moreover, a fifth installation cavity 17 with an upward opening is formed among the bending part 16, the U-shaped wall 12 and the flat plate 11 described above. The fifth installation cavity 17 can be used to install the feet of the base 4 at the end of the fifth installation cavity to realize the assembly of the slide rail 1 and the base 4, and can also be used to install an atmosphere lamp, etc. in the middle of the fifth installation cavity.

[0090] The above-mentioned first installation cavity 138, second installation cavity 139, third installation cavity 15, clearance cavity 141, fourth installation cavity 161, and fifth installation cavity 17 are integrated on a slide rail 1, enabling the slide rail 1 to have multiple functions.

[0091] It should be noted that the usage methods of the above-mentioned first installation cavity 138, second installation cavity 139, third installation cavity 15, clearance cavity 141, fourth installation cavity 161, and fifth installation cavity 17 in other embodiments should not be limited by the above-mentioned usage methods in this embodiment, as long as they are reasonable assembly and usage methods that can be achieved by those skilled in the art.

[0092] Here is a possible structural solution for the base 4:

[0093] As Figure 4 、 Figure 5 、 Figure 6 、 Figure 15 、 Figure 17 , the outer side wall of the base 4 has a connecting part 41 for installing the connecting part 41 on the top surface of the left side of the U-shaped wall 12 of the slide rail 1 through screws, thereby realizing the fixed connection between the base 4 and the slide rail 1; moreover, an avoidance groove 42 corresponding to the outer contour of the top of the slide rail 1 (i.e., the first inclined wall 133 and the transverse wall 135) is formed on the bottom surface of the base 4, thereby reducing the overall height after the base 4 is stacked and installed on the top of the slide rail 1; a rotation hole 43 is formed at one end of the inner side wall of the base 4 for rotatably assembling with the reel assembly 2; a connecting column 44 is formed in the middle of the inner side wall of the base 4, and a pressure strip is installed between the connecting columns 44 of the two bases at the same end. The pressure strip is used to press on the curtain cloth, having the effect of preventing the curtain cloth from warping.

[0094] Moreover, a guiding seat 45 is formed at the lower part of the inner side wall of the base 4. An installation notch 101 is formed on the inner side surface of one end of the slide rail 1 where the base 4 is installed. The guiding seat 45 is placed in the installation notch 101. An installation support foot 451 is formed at the end of the guiding seat 45. By snapping the installation support foot 451 into the fifth installation cavity 17 of the slide rail 1, the assembly of the base 4 and the slide rail 1 is realized. At the same time, a sloping guiding part 452 with a certain slope extends upward at this end of the guiding seat 45. When the base 4 and the slide rail 1 are assembled, the sloping guiding part 452 corresponds to the top surface position of the right side of the U-shaped wall 12 of the slide rail 1, facilitating the smooth introduction of the curtain cloth into the third installation cavity 15 of the slide rail 1 and preventing the curtain cloth from being scratched and damaged by the end face of the slide rail when entering the slide rail 1.

[0095] Through the installation method of the base 4, the slide rail 1, and the mounting foot 61 of the wire tube connecting seat 6 provided above, the three are assembled in a stacked and distributed manner, which can fully ensure the thickness space of the curtain cloth and reduce the overall height of the frame, which is conducive to adapting to the diversity of the rear-installation space of the sunshade brought by the interior space of different car models.

[0096] Moreover, fasteners are used to better ensure that the base 4, the slide rail 1, and the wire tube connection seat 6 are installed firmly. For example, screws are used. Installation holes are opened on the connection part 41 of the base 4, the top surface of the U-shaped wall 12 of the slide rail 1, and the installation foot 61 of the wire tube connection seat 6. The three are connected and fastened by installing screws (not shown in the figure). It is particularly noted that after the fasteners (such as screws) are installed, the exposed part of the fasteners shall not exceed the top surface of the base 4 and the bottom surface of the slide rail 1. The top surface of the base 4 is used 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, and the fasteners do not exceed the top surface of the base. In this way, it is ensured that the fasteners will not accidentally scratch the skylight glass or other interior decorations when the sunshade frame is installed. The fasteners do not exceed the bottom surface of the slide rail 1, which ensures the flat design of the bottom surface of the slide rail 1, which is convenient for bonding to the flat interior panel 3.

[0097] At the same time, the above-mentioned 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 slide rails 1 on both sides (that is, 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, and the wire tube connecting seat 6 is installed on the upper surface of the front beam 7.

[0098] At the same time, the frame also includes a rear beam 8 bonded to the upper surface of the plane interior panel 3, the rear beam 8 also has a planar bottom surface, the rear beam 8 is connected to the rear ends of the slide rails 1 on both sides, and the bottom surface of the rear beam 8 is flush with the bottom surface of the slide rail 1. The design that the bottom surfaces of the front beam 7, the slide rail 1, and the rear beam 8 are flush and planar facilitates the overall bonding of the three to the upper surface of the plane interior panel 3.

[0099] For flat interior panels with different widths on both sides, such as Figure 1 , Figure 8 The front side of the flat interior panel is wider than the rear side, so the front beam 7 corresponding to the front side adopts a longer beam, so that the two ends of the beam respectively extend beyond the two side rails 1, which helps to enhance the strength of the flat interior panel 3 where the extending portion is located, and reduce the bending damage of the flat interior panel 3 during transportation.

[0100] At the same time, mounting plates 9 are provided on the front beam 7 and the rear beam 8. The mounting plates 9 are inserted into the gap between the sunroof and the interior of the car, so that the sunshade can be retrofitted to the sunroof. The sunshade product or sunshade frame is suitable for the retrofit market, and the retrofitting method that requires the removal or destruction of the original interior of the car should be avoided as much as possible.
