[0049] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail in combination with the drawings and examples. It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0050] The automobile sunroof sunshade curtain comprises a sunshade curtain frame, a reel assembly and the like. The frame is provided with a curtain cloth which is installed on the frame and moves back and forth to open and close. The sunshade curtain is installed on the automobile sunroof in a post-installation mode. The sunshade curtain is installed on the automobile sunroof after sale, and plays a sunshade role according to requirements.

[0051] As Figure 1 , Figure 8, sunshade curtain frame, comprising a flat interior panel 3, two slide rails 1, a base 4 and other components; two slide rails 1 are respectively installed on the left and right sides of the flat interior panel 3, and the slide rails 1 can provide the curtain fabric of the sunshade curtain with reciprocating movement along the slide rails 1; the base 4 is installed on the slide rails 1, and the two bases 4 at the same end of the slide rails 1 are rotatably installed with a rotatable spool assembly 2 (not shown in the figure) that makes the curtain fabric of the sunshade curtain do winding and unwinding operations Figure 1 The spool assembly 2 is prior art knowledge and is not described in detail.

[0052] As Figure 1 , Figure 8 The flat interior panel 3 has a window 31 in the middle, and when the sunshade curtain is installed on the car sunroof, the window 31 is located at the car sunroof. Under normal circumstances, the person inside the car cannot see the spool assembly 2 through the window 31, and when the curtain fabric of the sunshade curtain is unfolded to cover the window 31, it is used for sunshade, and when the curtain fabric is wound up and does not cover the window 31, sunlight can shine into the car. The window 31 is a design that the interior panel of the traditional car sunroof sunshade curtain also has, and will not be described in detail.

[0053] The difference is that the flat interior panel 3 here is assembled from two flat panels 32, and in other embodiments it can also be composed of one flat panel, and the upper surface and lower surface of the flat interior panel 3 are both flat structures. The development cost and manufacturing cost of this flat interior panel 3 are relatively low, and it has better economic benefits. At the same time, compared with the interior panel with a curved surface structure, it can also save the height space occupied when the sunshade curtain is installed in the car.

[0054] The above-mentioned bases 4 are respectively stacked on the top of the corresponding slide rails 1, and the bases 4 are provided with rotating holes 43 (such as Figure 2 , Figure 3 As Figure 9 , Figure 10 , Figure 11 ), so that the rotating holes 43 of the bases 4 are elevated to a higher height, and better make full use of the scene conditions after the car is installed, so that the position of the rotating holes 43 is higher than the top surface of the slide rails 1, and the flat structure design of the flat interior panel 3 is considered, so that the rotating holes 43 of the bases 4 and the flat interior panel 3 form a larger spacing, which can provide sufficient winding thickness space for the winding curtain fabric after the spool assembly 2 is installed on the base 4, and is especially suitable for scenes with large winding thickness after the single-opening sunshade curtain is wound. The design idea of recessing the end of the interior panel corresponding to the spool assembly to form a curved surface structure in order to provide sufficient space for the spool assembly with large winding thickness after winding is abandoned in the traditional frame.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] There are multiple ways to assemble the base 4, slide rail 1, and conduit connector 6. This article mainly describes the following two embodiments:

[0060] Example 1:

[0061] like Figures 1 to 3 The 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.

[0062] A mounting foot 61 extends from one side of the conduit connector 6, such as Figure 4The bottom surface of the mounting foot 61 is flush with the bottom surface of the wire tube connecting seat 6, and the mounting foot 61 is inserted into the end portion of the sliding rail 1 to realize the connection of the two, and the sliding rail 1 has a cavity for the insertion of the mounting foot 61, and at the same time, the design feature that the mounting foot 61 is flush with the bottom surface of the wire tube connecting seat 6 and the insertion mode with the sliding rail 1 make the wire tube connecting seat 6 not exceed the overall height of the sliding rail 1 after being installed on the sliding rail 1, thereby saving the height occupied by the overall frame and realizing the connection of the wire tube connecting seat 6 on the sliding rail 1 and the assembly of the two. After the assembly of the mounting foot 61 inserted into the end portion of the sliding rail 1, the wire tube connecting seat 6 is located at the outer front side of the end portion of the sliding rail 1.

[0063] As Figure 4 , the mounting foot 61 of the wire tube connecting seat 6 is formed with a avoiding groove 611 for avoiding the W-shaped transition wall 13 on the sliding rail 1, and when the sliding rail 1 is assembled with the mounting foot 61, the W-shaped transition wall 13 at the end portion of the sliding rail 1 is placed in the avoiding groove 611, and the flexible shaft can move in the wire tube 52 and the sliding rail 1. At the same time, in order to facilitate the assembly of the mounting foot 61 and the sliding rail 1, the flat plate 11 on the end portion bottom surface of the sliding rail 1 corresponding to the mounting foot 61 of the wire tube connecting seat 6 can be removed, that is, the position of the end portion bottom surface of the sliding rail 1 corresponding to the mounting foot 61 of the wire tube connecting seat 6 does not have the flat plate 11.

[0064] Through the above installation mode of the base 4, the sliding rail 1, and the mounting foot 61 of the wire tube connecting seat 6, the connection of the three can be realized, and at the same time, the three are in a stacked distribution state, which sufficiently guarantees the thickness space of the curtain rolling and reduces the overall height of the frame, and is beneficial to adapt to the variety of rear installation space of the sunshade curtain in different vehicle interiors.

[0065] At the same time, as Figure 4 , Figure 7 , the wire tube connecting seat 6 is installed with an upper cover 62, and the wire tube connecting seat 6 and the upper cover 62 are respectively formed with corresponding wire grooves 63, and the corresponding wire grooves 63 of the two are combined to form a wire hole 64 after the assembly of the wire tube connecting seat 6 and the upper cover 62. The wire hole 64 can be passed through by the wire tube 52, so as to realize the radial positioning of the wire tube 52 when the upper cover 62 is fixed on the wire tube connecting seat 6. After the installation of the wire tube 52, the flexible shaft passing through the wire tube 52 can be smoothly placed into the sliding rail 1 to drive the movement of the curtain.

[0066] Moreover, in order to guarantee the axial positioning effect of the wire tube 52, a positioning ring is formed on the outer side wall of the wire tube 52 near the end portion, and a positioning groove 631 is formed on the wire tube connecting seat 6, and 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 only one form of the positioning protrusion formed on the outer side wall of the wire tube 52, and a positioning protrusion 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, the positioning groove is provided on the wire tube, and the positioning protrusion is correspondingly provided on the wire tube connecting seat; these alternative forms are conventional means and will not be described in detail.

[0067] Embodiment 2

[0068] As Figures 8 to 12 , the base 4 is stacked and installed on the top of the slide rail 1, and the part where the rotating hole 43 on the base 4 is located is beyond the end of the slide rail 1 along the length direction of the slide rail 1, that is, the rotating hole 43 does not correspond to the position above the slide rail 1, and the wire tube connecting seat 6 is placed at the outer side position corresponding to the end of the slide rail 1 (that is, the front side of the end of the slide rail along the length direction of the slide rail), and the part where the rotating hole 43 on the base 4 is located corresponds to the position above the wire tube connecting seat 6. Figure 2

[0069] As for the specific positional relationship of the base 4 stacked and installed on the top of the slide rail 1, the embodiment 2 is different from the embodiment 1 in that, as Figure 3 and Figure 11 , the positions of the part where the rotating hole 43 on the base 4 is located relative to the front end of the slide rail 1 are different, and in the embodiment 2, the part where the rotating hole 43 is located is closer to the front side of the planar interior trim panel 3 than in the embodiment 1, so that after the reel assembly 2 is installed, the reel assembly 2 is closer to the front side of the planar interior trim panel 3, and in this way, the window 31 can be widened along the length direction of the slide rail 1, that is, the planar interior trim panel 3 assembled by using the embodiment 2 has a wider window 31 than the planar interior trim panel 3 assembled by using the embodiment 1, and in the scene that the type of the automobile sunroof is consistent and the space for additional installation in the vehicle is limited, the planar interior trim panel 3 with a wider window 31 can have a wider field of view after the sunshade curtain is opened. That is to say, the embodiment 2 can not only expand the winding space of the reel assembly 2 by stacking the base 4 on the slide rail 1, but also can widen the window 31 of the planar interior trim panel 3 by changing the assembly relationship between the base 4 and the slide rail 1.

[0070] It should be emphasized that, as Figure 2 , Figure 3 , although the rotating hole 43 of the base 4 and the front end of the base 4 do not exceed the front end of the slide rail 1 in the embodiment 1, as Figure 10 , Figure 11 ​, the rotating hole 43 of the base 4 and the front end of the base 4 in Embodiment 2 both exceed the front end of the slide rail 1, but Embodiment 2 embodies the design idea 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 compared with Embodiment 1, then, in other embodiments, the design scheme of moving the rotating hole 43 of the base 4 forward without exceeding the front end of the slide rail 1 and moving the front end of the base 4 away from the front end of the slide rail 1 also still falls within the protection scope of the design idea herein.

[0071] As shown in Figure 14 , the wire tube connecting seat 6 is formed with a wire slot 63 opening upward, and the bottom of the end of the base 4 exceeding the end of the slide rail 1 is formed with a wire slot 63 opening downward, as shown in Figure 18 , after the wire tube connecting seat 6 is assembled with the base 4, the corresponding wire slots 63 of the two then jointly enclose a wire hole 64, as shown in Figure 10 , Figure 16 The wire hole 64 can be passed through by the wire tube 52, so as to realize the radial positioning of the wire tube 52 when the base 4 is assembled with 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 fabric to move.

[0072] In Embodiment 2, the form of the wire hole 64 relative to Embodiment 1, the end of the base 4 exceeding the end of the slide rail 1 has the “upper cover” function in Embodiment 1.

[0073] One side surface of the wire tube connecting seat 6 extends a mounting foot 61, as shown in Figure 17 , Figure 13 , Figure 14 The bottom surface of the mounting foot 61 is flush with the bottom surface of the wire tube connecting seat 6, the mounting foot 61 is inserted into the end of the slide rail 1, the slide rail 1 is provided with a cavity for the insertion of the mounting foot 61, and meanwhile, by virtue of the design features that the bottom surface of the mounting foot 61 is flush with the bottom surface of the wire tube connecting seat 6 and the insertion mode with the slide rail 1, the wire tube connecting seat 6 does not exceed the overall height of the slide rail 1 after being mounted on the slide rail 1, thereby saving the height occupied by the frame as a whole and realizing the connection and assembly of the wire tube connecting seat 6 on the slide rail 1. After being assembled by inserting the mounting foot 61 into the end of the slide rail 1, the wire tube connecting seat 6 is located at the outer front side of the end of the slide rail 1.

[0074] As shown in Figure 18 , the bottom of the end of the base 4 exceeding the end of the slide rail 1 extends downward to form a clamping groove 47 for clamping the wire tube connecting seat 6, and the wire tube connecting seat 6 is clamped on the bottom of the base 4 to realize the assembly of the two. In other embodiments, other specific implementation means of clamping installation can also be adopted for the wire tube connecting seat and the bottom of the end of the base.

[0075] In order to accurately determine the assembly position of the base 4, the wire tube connecting seat 6 and the slide rail 1, reference is made to Figure 13 , Figure 14A positioning block 65 is formed on the wire tube connecting seat 6, and the mounting leg 61 is inserted into the slide rail 1, and the front end surface of the slide rail 1 abuts against the side surface of the positioning block 65 to achieve positioning. Figure 18 The side surface of the slide rail 1 corresponding to the above-mentioned clamping groove 47 of the base 4 is the positioning surface 49 of the base 4, and when the base 4 is installed on the slide rail 1, the front end surface of the slide rail 1 abuts against the positioning surface 49 of the clamping groove 47; of course, a rib plate 48 can also be formed on the bottom of the end of the base 4 beyond the end of the slide rail 1, and the rib plate 48 corresponds to the side surface of the slide rail 1 to form the positioning surface 49 of the base 4, and when the base 4 is installed on the slide rail 1, the front end surface of the slide rail 1 abuts against the positioning surface 49 of the rib plate 48 to achieve the positioning effect.

[0076] The wire tube 52 is installed in the wire hole 64, and the end thereof is subjected to hole expansion treatment (the hole expansion treatment is to expand the diameter of the end hole, and the expansion means is the prior art), and the end of the wire tube after the hole expansion treatment is referred to as the expanded hole end, and the hole expansion position is referred to as the expanded hole portion 521. Figure 13 The inner diameter of the expanded hole portion 521 is naturally larger than the inner diameter of other portions of the wire tube after the hole expansion treatment, so that the end surface of the expanded hole portion 521 does not touch the flexible shaft during the reciprocating movement of the flexible shaft, and the end surface of the wire tube 52 is prevented from scratching and damaging the flexible shaft.

[0077] As shown in Figure 13 , Figure 14 When the front end surface of the slide rail 1 abuts against the side surface of the positioning block 65, a gap space 66 is formed between the front end surface of the slide rail 1 and the side surface 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 expanded hole portion 521 is arranged in the gap space 66; at the same time, the bottom of the base 4 is also formed with a containing groove 46 corresponding to the position of the gap space 66 for containing the expanded hole portion 521. Figure 17 , Figure 18 .

[0078] As shown in Figure 17 , Figure 14 The mounting leg 61 of the wire tube connecting seat 6 is formed with an avoiding groove 611 for avoiding the W-shaped transition wall 13 on the slide rail 1, and the avoiding groove 611 is communicated with the gap space 66 and the wire groove 63, and when the slide rail 1 and the wire tube connecting seat 6 are assembled, the W-shaped transition wall 13 on the end of the slide rail 1 is arranged in the avoiding 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 on the end surface of the slide rail 1 corresponding to the mounting leg 61 of the wire tube connecting seat 6 can be removed, that is, the end surface of the slide rail 1 corresponding to the position of the mounting leg 61 of the wire tube connecting seat 6 does not have the flat plate 11.

[0079] Furthermore, in order to guarantee the axial positioning effect of the wire tube 52, a positioning ring is formed on the outer side wall of the wire tube 52 close to the end portion, and a positioning groove 631 is formed on the wire tube connecting seat 6.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.

[0080] 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.

[0081] Here is one possible structural design for slide rail 1:

[0082] 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.

[0083] 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.

[0084] The first end face of the transition wall 13 (i.e. the left end face of the left portion 131) and the second end face (i.e. the middle end face) of the middle portion are respectively inclined upward to correspond to the first inclined wall 133 and the second inclined wall 134, the top end of the first inclined wall 133 intersects with the top end of the second inclined wall 134 and then extends a transverse wall 135, the first inclined wall 133 and the second inclined wall 134 enclose the second closed cavity 136 with the left portion 131 of the W-shaped transition wall 13, and the first inclined wall 133 extends a protruding portion 137 toward the second closed cavity 136, the protruding portion 137 and the left portion 131 of the transition wall 13 enclose an arc-shaped first mounting cavity 138 at the lower part of the second closed cavity 136, which can be used to accommodate the flexible shaft and allow the flexible shaft to move in 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.

[0085] The third end face of the transition wall 13 (i.e. the right end face of the right portion 132) extends a bent wall 14 upward, the bent wall 14 is located below the transverse wall 135 and forms a gap cavity 141 with the transverse wall 135, the gap cavity 141 is communicated with the second mounting cavity 139, and the end of the pull rod (or the sliding block installed at the end) for pulling the curtain to move can move in the gap cavity 141. The moving end of the curtain in the reel assembly 2 (the end of the curtain connected to the reel is called the winding end, and the moving end is opposite to the winding end) is provided with a pull rod, and the end of the pull rod moves in the slide rail, which is a conventional means and will not be described here.

[0086] Meanwhile, the second inclined wall 134, the right portion 132 of the W-shaped transition wall 13 and the bent wall 14 enclose an arc-shaped second mounting cavity 139, which can be used to accommodate the flexible shaft and allow the flexible shaft to move in the cavity. The first mounting cavity 138 and the second mounting cavity 139 can radially constrain the side wall of the flexible shaft with a circular cross section by means of the arc-shaped design to prevent the flexible shaft from bending, while having a moving guide function.

[0087] Meanwhile, the bent wall 14 and the top face of the right side of the U-shaped wall 12 (i.e. the top face located on the right side of the transition wall) enclose a third mounting cavity 15 with an opening toward the inside of the slide rail 1, which can allow the hem bar of the side edge of the curtain to move in the third mounting cavity 15, i.e. to place the side edge of the curtain in the slide rail 1, so as to avoid the existence of a transverse gap between the curtain and the slide rail 1 to cause a leakage gap phenomenon.

[0088] The top surface of the right side of the U-shaped wall 12, the bending wall 14 and the transverse wall 135 are vertically arranged in sequence and are spaced apart. The W-shaped transition wall is concave, and the first inclined wall 133 and the second inclined wall 134 are designed to be inclined, which reduces the height of the transverse wall 135. On this basis, 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 on the left side of the transition wall), which reduces the height of the bending wall 14. Under the premise of fully guaranteeing the use space height of the gap cavity 141 and the third mounting cavity 15, the overall height of the slide rail 1 is further reduced, and the occupied space in the vehicle is saved.

[0089] Moreover, the inner side of the bending wall 14 extends downward to form a hook portion 142, which is curved toward the third mounting cavity 15. The hook portion 142 can be used to form a transverse constraint on the folded edge strip to prevent the side edge of the curtain from being transversely detached from the slide rail 1, and can also improve the transverse tension of the curtain.

[0090] Better, the other side of the upper surface of the flat plate 11 extends upward to form a bending portion 16, which encloses a fourth mounting cavity 161 with the upper surface of the flat plate 11 and the U-shaped wall 12. The fourth mounting cavity 161 can be used to install an atmosphere lamp.

[0091] Moreover, the bending portion 16, the U-shaped wall 12 and the flat plate 11 enclose a fifth mounting cavity 17, which is open upward. The fifth mounting cavity 17 can be used to install the legs of the base 4 to realize the assembly of the slide rail 1 and the base 4, and can be used to install an atmosphere lamp and the like in the middle of the fifth mounting cavity.

[0092] 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 are integrated on one slide rail 1, so that the slide rail 1 has multiple functions

[0093] It should be noted that the use mode 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 by the use mode described above in this embodiment, as long as it is a reasonable assembly use mode that can be realized by those skilled in the art.

[0094] Here is a possible structure scheme of the base 4:

[0095] As Figure 4 , Figure 5 , Figure 6 , Figure 15 , Figure 17The outer side wall of the base 4 has a connecting part 41, which is installed 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. In addition, the bottom surface of the base 4 is provided with an avoiding groove 42 corresponding to the outer shape contour (i.e. the first inclined wall 133 and the transverse wall 135) of the top part of the slide rail 1, thereby reducing the overall height of the base 4 after being stacked and installed on the top part of the slide rail 1. The inner side wall of the base 4 is provided with a rotating hole 43 at one end, which is used for rotatably assembling with the reel assembly 2. The inner side wall of the base 4 is formed with a connecting column 44 at the middle part, and the connecting columns 44 of the two bases at the same end are used for installing a pressing strip, which is used for pressing on the curtain cloth and has the effect of preventing the curtain cloth from being raised.

[0096] In addition, the inner side wall of the base 4 is formed with a guide seat 45 at the lower part, and the inner side surface of one end of the slide rail 1, on which the base 4 is installed, is provided with an installation notch 101. The guide seat 45 is arranged in the installation notch 101. The guide seat 45 is formed with an installation leg 451 at the end part. The installation leg 451 is clamped into the fifth installation cavity 17 of the slide rail 1, thereby realizing the assembly of the base 4 and the slide rail 1. In addition, the end part of the guide seat 45 is upwardly extended and formed with an inclined guide part 452 with a certain slope. When the base 4 is assembled with the slide rail 1, the inclined guide part 452 corresponds to the position of the top surface of the right side of the U-shaped wall 12 of the slide rail 1, thereby 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 damaged by being scratched by the end surface of the slide rail when entering the slide rail 1.

[0097] Through the above-mentioned installation mode of the base 4, the slide rail 1 and the installation leg 61 of the wire pipe connecting seat 6, the three are stacked and distributed for assembly, thereby sufficiently guaranteeing the curtain cloth winding thickness space and reducing the overall height of the frame, which is beneficial to adapt to the variety of rear installation spaces of the sunshade curtain caused by the interior space of different vehicle models.

[0098] In addition, fasteners are used to better guarantee the stable installation of the base 4, the slide rail 1 and the wire pipe connecting seat 6. For example, screws are used. Installation 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 installation leg 61 of the wire pipe connecting seat 6, and installation screws (not shown in the figure) are used to connect and fasten the three. It should be noted that after the fasteners (such as screws) are installed, the exposed part of the fasteners should 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 overall frame, and the top surfaces of other components in the frame should not be higher than the top surface of the base 4. The fasteners should not exceed the top surface of the base. In this way, it is guaranteed that the fasteners will not scratch the sunroof glass or other interior during the rear installation operation of the sunshade frame. The fasteners should not exceed the bottom surface of the slide rail 1, so as to guarantee the planar design of the bottom surface of the slide rail 1, thereby facilitating the bonding to the planar interior panel 3.

[0099] Meanwhile, the frame further comprises a front beam 7 adhered to the upper surface of the planar interior panel 3, the front beam 7 has a planar bottom surface, the front beam 7 is located at the front end of the two side 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 side rail 1, and the wire tube connecting seat 6 is mounted on the upper surface of the front beam 7.

[0100] Meanwhile, the frame further comprises a rear beam 8 adhered to the upper surface of the planar interior panel 3, the rear beam 8 also has a planar bottom surface, and the rear beam 8 is connected to the rear end of the two side rails 1, and the bottom surface of the rear beam 8 is flush with the bottom surface of the side rail 1. By designing the bottom surfaces of the front beam 7, the side rail 1 and the rear beam 8 to be flush and planar, the three can be integrally adhered to the upper surface of the planar interior panel 3.

[0101] For planar interior panels with different widths, such as Figure 1 , Figure 8 the front side of the planar interior panel is wider than the rear side, then the front beam 7 corresponding to the front side adopts a longer beam, so that the two ends of the beam respectively protrude from the two side rails 1, which helps to enhance the strength of the planar interior panel 3 at the protruding position and reduce the bending damage of the planar interior panel 3 during transportation.

[0102] Meanwhile, mounting plates 9 are arranged on the front beam 7 and the rear beam 8, and the sunshade curtain can be integrally retrofitted on the sunroof of the vehicle by inserting the mounting plates 9 into the gap between the sunroof and the interior trim of the vehicle. The sunshade curtain product or the sunshade curtain frame is suitable for the retrofit market, and should avoid using retrofit methods that require disassembly or damage to the original interior trim of the vehicle.
