TECHNICAL FIELD
[0001] The utility model relates to the technical field of automobile parts, especially relates to a roof assembly. BACKGROUND
[0002] With the gradual improvement of people's requirements for automobile configuration, in most vehicle models, the roof will be equipped with a sky glass, and a window is opened on the automobile roof to allow light to pass through the sky glass and enter the vehicle. The sky glass not only improves the external appearance of the top of the vehicle, but also greatly improves the lighting of the automobile roof. At the same time, to meet the diversified needs of people, when there is no need for lighting, the sky glass needs to be shaded, so a sunshade curtain is installed corresponding to the window on the automobile roof, so that the window can be flexibly closed or opened.
[0003] According to the conventional design, the existing sunshade curtain configuration of the automobile roof occupies a large space of the automobile roof, and the reel and the driving device in the sunshade curtain need to be buried between the inner and outer decorative plates of the automobile roof, thereby requiring an increase in the thickness of the automobile roof, which inevitably reduces the height space of the passenger compartment, resulting in an inability to meet the head space requirements of the people in the passenger compartment.
[0004] For the case where the reel is arranged at the rear of the roof, especially in three-box vehicle models, the rear of the roof usually has a downward inclined slope shape, which makes the installation space at the rear of the roof smaller, which is not conducive to the installation of the reel. The reel needs to be moved forward accordingly, which inevitably shortens the overall length of the sky glass, thereby failing to maximize the transparent area of the sky glass. Arranging the reel in the middle or front of the roof requires a large height space for the height of the reel itself and the structure of the cloth outlet, thereby reducing the height space in the area near the reel in the passenger compartment, which limits the interior height of the whole vehicle due to the roof shape, thereby failing to meet the space requirements of the human head in the vehicle.
[0005] In view of the above problems, it is urgent to research and optimize the structure and arrangement of the sunshade curtain in the automobile roof to improve the above problems. CONTENT OF THE UTILITY MODEL

[0050] The present application will be described in detail below with reference to the drawings and in combination with the embodiments.
[0051] Embodiment one
[0052] The present embodiment relates to a ceiling assembly, and provides an arrangement scheme of a double sunshade curtain; an exemplary structure is as shown in Figure 1 andFigure 2 As shown.
[0053] Overall, the ceiling assembly includes a ceiling frame 6 provided with a window 61, and a front sunshade curtain 1 and a rear sunshade curtain 2 for shielding the window 61. Among them, the ceiling frame 6 is provided with a middle cross beam 62, and the window 61 includes a front window 611 and a rear window 612 located on the front and rear sides of the middle cross beam 62 respectively. The front sunshade curtain 1 includes a front roller 12 arranged on the side of the middle cross beam 62 close to the front window 611, and a front curtain cloth 10 wound on the front roller 12. The rear sunshade curtain 2 includes a rear roller 23 arranged on the side of the middle cross beam 62 close to the rear window 612, and a rear curtain cloth 20 wound on the rear roller 23.
[0054] It should be pointed out that based on the overall design idea described above, the technical scheme of the present application can adopt various different specific implementation structures, forms or configuration sequences. For example, the front sunshade curtain 1 and the rear sunshade curtain 2 described above can adopt the same or different driving structure forms, and the curtain exit positions of the two sunshade curtains can be at the top or bottom of the roller. The specific arrangement sequence, assembly method, etc. of the front sunshade curtain 1, the rear sunshade curtain 2, and the middle cross beam 62, etc. can also be flexibly adjusted. For the parts required for the implementation of the overall scheme but not involved in the above overall arrangement, reasonable and flexible design can be made by referring to the mature setting means in the art, the actual situation during implementation, etc. The specific implementation scheme described below in this embodiment is only one of the relatively optimal schemes formed by various combinations and changes of the above, and in actual implementation, the skilled in the art can make flexible adjustments and improvements in combination with the actual situation. Obviously, the various specific form combinations and changes of the above can form many schemes, and the specific implementation scheme of this embodiment is within the protection scope of the present application.
[0055] Based on the above design idea, as Figure 1 , Figure 2 and in combination with Figure 3 , Figure 4As shown, the roof assembly in this embodiment mainly includes a roof frame 6, a skylight glass 60 covering the top of the roof frame 6, a front sunshade 1 provided at the front window 611 corresponding to the front side of the central beam 62, and a rear sunshade 2 provided at the rear window 612 corresponding to the rear side of the central beam 62. The structural configuration of the rear sunshade 2 and the front sunshade 1 will be described below. The central beam 62 is provided based on the arrangement of the front window 611 and the rear window 612. It can be a supporting beam structure on the roof frame 6 or a supporting plate structure on the interior panel 64. In this embodiment, the interior panel 64 located between the front window 611 and the rear window 612 and the corresponding skeleton on the roof frame 6 together constitute the central beam 62. The aforementioned front roller 12 and rear roller 23 are both hidden in the cavity formed between the interior panel 64 and the roof frame 6.
[0056] To facilitate understanding and description of the solution, taking a vehicle roof as an example, in the case of a sunroof 60, a central crossbeam 62 is set at the middle position of the window 61 corresponding to the sunroof 60. A rear window 612 is formed behind the central crossbeam 62. In this embodiment, the rear sunshade 2 is located at the rear window 612. Taking the case where the rear curtain 20 extends towards the rear of the vehicle as an example, the aforementioned direction of curtain extension is... Figures 5 to 7 The direction indicated by T, i.e., the direction of the curtain exit, is exactly opposite to the X-direction of the vehicle. The frame 25 of the rear sunshade 2 is fixed to the roof frame 6, and a guide groove is provided on the frame 25. The edge of the rear curtain 20 can be guided and positioned within this guide groove. The end of the rear curtain 20 is fixed to the rear end rod 21, and both ends of the rear end rod 21 are guided and positioned in the guide grooves of the corresponding side frame 25, and connected to a transmission cable 22. The transmission cable 22 is connected to the drive device 24. Under the drive of the drive device 24, the transmission cable 22 can pull the rear end rod 21 to move horizontally along the curtain exit direction, and simultaneously drive the rear roller 23 to rotate, so as to pull the rear curtain 20 out from the rear roller 23 to unfold the rear curtain 20, or to roll the rear curtain 20 back onto the rear roller 23 to retract the rear curtain 20. Preferably, the drive device 24 in this embodiment is driven by a motor to accommodate the large size of the rear window 612 in the X direction of the vehicle and the long extension distance of the rear sunshade 2. Both ends of the aforementioned rear roller 23 are fixed to the roof frame 6 via the first mounting base 231.
[0057] like Figures 5 to 10As shown, the rear sunshade curtain 2 of the embodiment is arranged in a direction of the rear of the vehicle, and the out-cloth point 200 of the rear curtain cloth 20 is located at the bottom of the rear roller 23. Meanwhile, the rear sunshade curtain 2 further comprises a first guide crossbeam 3 arranged at the out-cloth side of the rear roller 23. The first guide crossbeam 3 is arranged parallel to the axis 230 of the rear roller 23 and presses the rear curtain cloth 20 from below. Under the pressing and guiding of the first guide crossbeam 3, the pulled-out rear curtain cloth 20 is divided into an unfolded section 202 located at the out-cloth direction side of the first guide crossbeam 3 and an out-rolling section 201 located between the first guide crossbeam 3 and the rear roller 23. The out-rolling section 201 and the unfolded section 202 are relatively bent, and the unfolded section 202 is parallel to the out-cloth direction.
[0058] Referring to Figure 9 and Figure 10 As shown, the out-cloth point 200 of the out-rolling section 201 on the rear roller 23 is located at the bottom of the rear roller 23. Under the guiding of the first guide crossbeam 3, the out-rolling section 201 extends and is arranged from the out-cloth point 200 to the upper rear of the vehicle, and the unfolded section 202 is parallel to the out-cloth direction. A plane defined by the out-cloth point 200 of the out-rolling section 201 on the rear roller 23 and parallel to the out-cloth direction is a reference plane a, and a plane defined by the axis 230 and parallel to the out-cloth direction is a center plane b. Under the guiding of the first guide crossbeam 3, the out-rolling section 201 extends and is inclined to the side of the center plane b relative to the reference plane a. The out-rolling section 201 is parallel to the center plane b and located above the center plane b.
[0059] Still referring to Figure 9 and Figure 10 By arranging the first guide crossbeam 3, the height of the unfolded section 202 of the rear curtain cloth 20 can be lifted as a whole, so as to provide more space below (outside) the rear curtain cloth 20. Relative to the case without the first guide crossbeam 3, the unfolded section 202 of the rear curtain cloth 20 can be lifted to the height as shown in H of Figure 7 .
[0060] Specifically, by setting the first guide beam 3, an out-rolling angle c is formed between the out-rolling section 201 and the reference plane a, and the out-rolling angle c is preferably limited to below 40°. Since the position of the out-rolling point 200 of the out-rolling section 201 on the rear roller 23 changes with the change of the length of the rear curtain 20 being pulled out, i.e. the position of the reference plane a changes up and down, the out-rolling angle c between the out-rolling section 201 and the reference plane a changes with the pulling out of the rear curtain 20. By reasonably setting the distance between the first guide beam 3 and the rear roller 23 and the height position of the first guide beam 3 in the direction perpendicular to the reference plane a, the out-rolling angle c can be limited to a reasonable range; by controlling the out-rolling angle c to be below 40°, the transition angle between the out-rolling section 201 and the out-unrolling section 202 can always be kept above 140°, which can effectively reduce the contact area and pressure between the rear curtain 20 and the first guide beam 3, thereby reducing the resistance of the rear curtain 20 during the pulling out and retraction.
[0061] In addition, preferably, the first guide beam 3 of the present embodiment is arranged on the center plane b, i.e. the out-unrolling section 202 is lifted above the center plane b, that is, the out-unrolling section 202 is located on the side of the center plane b opposite to the reference plane a. By arranging the first guide beam 3 on the center plane b, the space outside the out-unrolling section 202 can be maximized. Taking the sunshade curtain in the roof of a vehicle as an example, when the rear roller 23 adopts the lower out-rolling mode, the out-rolling point 200 is located at the bottom of the rear roller 23, and the first guide beam 3 lifts the rear curtain 20 upward, so that the entire out-unrolling section 202 is located above the center plane b, thereby providing more generous space below the out-unrolling section 202, which can effectively improve the head space condition of the passengers.
[0062] As can be seen from the above, the curtain guiding structure in the rear sunshade curtain 2 of the present embodiment changes the inclination state of the out-rolling section 201 of the rear curtain 20 by using the first guide beam 3, so that the out-unrolling section 202 can be unrolled parallel to the out-rolling direction, and the transition part between the out-rolling section 201 and the out-unrolling section 202 is closer to the rear roller 23 under the lifting action of the first guide beam 3, so that the space on the outside of the rear curtain 20 opposite to the rear roller 23 is increased and more regular, thereby improving the space condition on the outside of the rear curtain 20 in the unrolled state of the sunshade curtain.
[0063] The specific arrangement of the first guide beam 3 can of course have various different structural schemes. In the present embodiment, as shown in the drawings, the first guide beam 3 is arranged on the out-rolling section 201 of the rear curtain 20, and the first guide beam 3 is arranged on the out-rolling section 201 of the rear curtain 20. Figure 11 and Figure 12As shown, the first guide beam 3 comprises a main body 30 and mounting portions 31 arranged at both ends of the main body 30, the mounting portions 31 are used to fix the first guide beam 3, and the main body 30 is formed with a guide portion for extruding the rear curtain fabric 20. In the embodiment, a plurality of mounting holes 310 are formed in the mounting portions 31, and the two ends of the first guide beam 3 are fixed to the corresponding side frame 25 through the mounting holes 310 by bolts, and are fixed to the roof frame 6 at the same time. By arranging the mounting portions 31 at both ends of the main body 30 of the first guide beam 3, the functional part and the mounting part of the first guide beam 3 are effectively separated, which not only facilitates the installation and fixation of the first guide beam 3, but also avoids the influence of the mounting structure of the first guide beam 3 on the rear curtain fabric 20. The guide portion on the main body 30 can well form extrusion and guide to the rear curtain fabric 20.
[0064] In addition, in order to ensure the stability of the first guide beam 3, based on the case that the interior panel 64 is fixed below the roof frame 6 and the automobile roof is fixed to the interior panel 64, a boss structure 640 can be arranged on the interior panel 64; when the two ends of the first guide beam 3 are connected to the roof frame 6, the boss structure 640 is arranged to abut against the bottom of the main body 30 of the first guide beam 3 at the same time, thereby forming effective support to the main body 30 of the first guide beam 3.
[0065] Specifically, as shown in Figure 10 and in combination with Figure 11 , Figure 12 As shown in the cross section of the main body 30, the guide portion is designed as a curved surface protruding towards the rear curtain fabric 20. By designing the guide portion as a curved surface, a good transition can be formed between the unwinding section 201 and the unfolding section 202, and the damage of the rear curtain fabric 20 caused by the friction between the first guide beam 3 and the surface of the rear curtain fabric 20 is reduced.
[0066] Of course, the first guide beam 3 can be made of solid structure, or made of profile with closed cross section. Preferably, the main body 30 of the first guide beam 3 in the embodiment comprises a bottom plate 300, a front side plate 301 and a rear side plate 302 integrally connected, the front side plate 301 and the rear side plate 302 are both bent relative to the bottom plate 300 and shaped to have convex curved surfaces for contacting the rear curtain 20, that is, the above-mentioned guide portions comprise a front guide portion 303 and a rear guide portion 304 shaped on the front side plate 301 and the rear side plate 302 respectively. The front guide portion 303 is located on the side of the rear guide portion 304 away from the rear roller 23, and the front guide portion 303 and the rear guide portion 304 are staggered in the direction perpendicular to the reference plane a, with the rear guide portion 304 located below the front guide portion 303. The front guide portion 303 and the rear guide portion 304 are arranged in front of and below each other, which not only can well guide and transition the rear curtain 20, but also can form a heat dissipation space between the front guide portion 303 and the rear guide portion 304, reducing the damage of the rear curtain 20 caused by continuous friction and overheating.
[0067] Based on the above arrangement, the air gap 305 is formed between the front side plate 301 and the rear side plate 302, and the air gap 305 makes the inner cavity 306 of the main body 30 communicate with the outside. The air gap 305 left between the rear side plate 302 and the front side plate 301 can make the heat space generated by the friction between the rear curtain 20 and the first guide beam 3 evenly distributed to the entire first guide beam 3 through the inner cavity 306, which is more conducive to heat transfer and dispersion, thereby improving the situation of the first guide beam 3 being overheated by friction. Based on the structural features of the first guide beam 3, the first guide beam 3 can be processed by bending or extrusion forming process of plate material, and the ends of the front side plate 301 and the rear side plate 302 are bent towards the inside of the first guide beam 3, which can well form the convex guide portion structure on the front side plate 301 and the rear side plate 302, and the air gap 305 required can be formed by arranging the ends of the front side plate 301 and the rear side plate 302 in a spaced manner.
[0068] For the arrangement of the front sunshade curtain 1, of course, there are many different structural schemes to choose from. In the embodiment, as shown in Figures 13 to 17 , a sunshade curtain structure scheme suitable for manual opening and closing is provided.
[0069] Overall, the front sunshade curtain 1 is arranged in the out-curtain direction towards the front of the vehicle, and the front sunshade curtain 1 is provided with a pull wire transmission mechanism 4; the end of the front curtain 10 is provided with a front end rod 11, and the pull wire transmission mechanism 4 comprises a pull wire 40 transmission connected between the front end rod 11 and the front roller 12, when the front end rod 11 is driven to move in the out-curtain direction by external force, the front roller 12 can be synchronously rotated to deploy or retract the front curtain 10 under the drive of the pull wire 40.
[0070] For the convenience of understanding, still taking the case that the front sunshade curtain 1 is arranged on the roof of the vehicle, the roof frame 6 is provided with a window 61, and the window 61 is provided with a sky curtain glass 60; the front sunshade curtain 1 of the embodiment is installed on the roof frame 6 corresponding to the window 61, and corresponds to the front window 611. By opening the front curtain cloth 10, the front window 611 can be shielded. As shown in Figure 13 In combination with Figure 17 It is shown that the front roller 12 can be fixed to the roof frame 6 through the second mounting seat 120 at both ends thereof; at the same time, the front sunshade curtain 1 of the embodiment further comprises a guide frame 5 fixed to the roof frame 6.
[0071] Specifically, the guide frame 5 of the embodiment comprises side frames 51 respectively arranged on both sides of the front curtain cloth 10, and the side frames 51 are provided with guide grooves 510 arranged in the out-curtain direction, and the side edge portions of the unfolded front curtain cloth 10 are located in the guide grooves 510. The guide frame 5 is arranged for the front sunshade curtain 1, which provides a good guide basis for the opening and closing action of the front curtain cloth 10, and can hide the edge portions of the front curtain cloth 10 in the guide grooves 510, thereby improving the protection of the front curtain cloth 10 and the stability of the opening and closing action of the front curtain cloth 10.
[0072] The specific arrangement structure of the front end rod 11 can be flexibly arranged, so as to realize the fixed connection between the end portion of the front curtain cloth 10 and the front end rod 11. In the embodiment, as shown in Figure 15 And Figure 16 , Figure 17 It is shown that the front end rod 11 is arranged along the width direction of the front curtain cloth 10, and the two ends of the front end rod 11 are respectively provided with guide blocks 111, the guide blocks 111 are slidingly arranged in the guide grooves 510 of the side frames 51, and the pull wire 40 is connected to the guide blocks 111. By arranging the guide blocks 111 at the end portions of the front end rod 11, a suitable connection position is provided for the connection between the pull wire 40 and the front end rod 11, and through the guide sliding cooperation of the guide blocks 111 and the guide grooves 510, the stability of the movement of the front end rod 11 is greatly improved, so that the opening and closing action of the front curtain cloth 10 is more stable, and the operation of the front end rod 11 is more smooth.
[0073] Based on the setting of the guide block 111, preferably, an elastic protrusion 112 can be arranged on the guide block 111, which is in abutting cooperation with the inner wall of the guide groove 510; the elastic protrusion 112 can be formed as an arched rib plate on the guide block 111, and the elastic abutting effect is achieved by the deformation of the rib plate itself. By arranging the elastic protrusion 112 on the guide block 111, the contact area between the guide block 111 and the inner wall of the guide groove 510 can be effectively reduced, thereby reducing the friction between the guide block 111 and the guide groove 510, and further reducing the resistance when driving the front end rod 11. In addition, a pulling groove 110 for manually pulling the front end rod 11 to move can also be arranged on the front end rod 11. The arrangement of the pulling groove 110 on the front end rod 11 provides a good force point for manually operating the front end rod 11, and the pulling groove 110 in the form of a groove can avoid occupying the external space of the front end rod 11.
[0074] In addition to the side frames 51, the guide frame 5 of the present embodiment further comprises end frames 50 connected between the side frames 51 on both sides, and the end frames 50 are located at the ends of the side frames 51 away from the front roller 12. When the front curtain 10 is unfolded, the front end rod 11 is clamped on the end frame 50. By arranging the end frames 50 between the side frames 51 on both sides, the overall structural integrity and stability of the guide frame 5 can be improved. At the same time, when the front curtain 10 is fully opened, the front end rod 11 can be clamped and cooperated with the end frame 50 to prevent the front end rod 11 from moving freely, so that the front curtain 10 in the fully opened state can be stably kept in the fully opened position.
[0075] The specific structure of the clamping cooperation can be designed flexibly, and in the present embodiment, in combination with the above-mentioned arrangement of the guide block 111, a clamping groove 113 can be arranged on the guide block 111, and a clamping block 500 is arranged on the end frame 50 correspondingly. When the front end rod 11 is pulled and the front curtain 10 is pulled to the fully opened position, the clamping block 500 can be clamped into the clamping groove 113. When it is needed to close the front curtain 10, the front end rod 11 is pulled away from the end frame 50, and the clamping block 500 can be pulled out of the clamping groove 113, and then the front curtain 10 can be closed.
[0076] As Figure 17Referring to the arrangement of the first guide beam 3, the front sunshade 1 in this embodiment also includes a second guide beam 13 disposed between the front roller 12 and the side frame 51. The second guide beam 13 presses against the front curtain 10 to guide the side edge of the front curtain 10 into and out of the guide groove 510. By providing the second guide beam 13 between the side frame 51 and the front roller 12, the position of the front curtain 10 can be raised by pressing and lifting the exit part of the front curtain 10. This not only helps to improve the space conditions under the front curtain 10, but also helps to support the front curtain 10 well, allowing the front curtain 10 to smoothly enter the guide groove 510 in a relaxed posture and move smoothly in the exit direction. Whether the second guide beam 13 is positioned above or below the front curtain 10 can be flexibly determined based on the position of the front curtain 10 exiting from the front roller 12. In this embodiment, the front curtain 10 exits from the front roller 12 at the top of the front roller 12, i.e., the front roller 12 adopts an upward exit method. In order to further raise the height of the front curtain 10 and create a more spacious space below the front curtain 10, the second guide beam 13 is positioned below the front curtain 10 and presses against the lower surface of the front curtain 10.
[0077] The specific configuration of the second guide beam 13 can be designed with reference to the configuration of the first guide beam 3; at the same time, both ends of the second guide beam 13 can be fixed to the ceiling frame 6, and the ends of the side frame 51, the second mounting base 120 mentioned above, and the guide rod mounting base 430 mentioned below can all be fixed to the ends of the second guide beam 13.
[0078] Still Figure 17 As shown, the cable drive mechanism 4 in this embodiment also includes a pulley 41 located at the end of the side frame 51 away from the front spool 12, and a spool-side rotating wheel 42 located at the end of the front spool 12; one end of the cable 40 is wound around the spool-side rotating wheel 42, and the other end passes around the pulley 41 and is connected to the front end rod 11. Specifically, a pulley holder 410 is inserted into the front end of the side frame 51, the top of the shaft of the pulley 41 is engaged with the pulley holder 410, and the bottom of the shaft of the pulley 41 is inserted into the end frame 50; in this way, the pulley 41 can be easily assembled and freely rotated, and the cable 40 can be wound around the pulley 41.
[0079] The pulley 41 and the shaft side rotating wheel 42 are arranged on the side frame 51 and the front roller 12 respectively, so that the guiding and transmission of the pull wire 40 can be realized smoothly, and the transmission effect between the translation of the front end rod 11 and the rotation of the front roller 12 is smooth. In the process of opening the front curtain 10, the front end rod 11 can drive the front roller 12 to rotate through the front curtain 10, and the pull wire 40 is wound on the shaft side rotating wheel 42; when closing the front curtain 10, the front end rod 11 close to the front roller 12 can drive the front roller 12 to rotate through the pull wire 40, so as to wind the front curtain 10 on the front roller 12; based on the above transmission requirements, the winding direction of the pull wire 40 on the shaft side rotating wheel 42 and the winding direction of the front curtain 10 on the front roller 12 should of course be opposite, so that a good transmission and force balance effect is formed between the front end rod 11, the front curtain 10, the front roller 12 and the pull wire 40.
[0080] Moreover, the peripheral surface of the shaft side rotating wheel 42 of the embodiment is formed with a winding track 420, the winding track 420 is helical along the axis of the front roller 12 and the radial dimension gradually decreases, and the pull wire 40 is wound on the winding track 420. By arranging the helical winding track 420 with gradually changing radial dimension on the shaft side rotating wheel 42, the pull wire 40 is wound on the shaft side rotating wheel 42 along the winding track 420, and the change of the radial dimension of the winding track 420 can be arranged according to the change of the radial dimension of the front curtain 10 in the opening or winding process of the front roller 12; in this way, the consistency of the rotation speed of the pull wire 40 driving the front roller 12 and the unwinding or winding speed of the front roller 12 can be ensured, so that the opening and closing action of the front curtain 10 is more smooth.
[0081] In addition, a pull wire groove 511 arranged along the curtain-out direction can be formed on the side frame 51, and the pull wire 40 can be arranged in the pull wire groove 511. Correspondingly, the pull wire transmission mechanism 4 of the present embodiment further comprises a guide rod 43 arranged between the shaft side rotating wheel 42 and the side frame 51, and the guide rod 43 can be rotatably arranged on a guide rod mounting seat 430 provided on the guide rod 43. The guide rod mounting seat 430 of the present embodiment is integrally formed with the second mounting seat 120 and is fixed on the mounting portion 31 of the second guide crossbeam 13. When the shaft 12 is used to roll out the curtain, the pull wire 40 is led out from the bottom of the shaft side rotating wheel 42, passes above the guide rod 43, and enters the pull wire groove 511. The guide rod 43 is pressed on the pull wire 40 to guide the pull wire 40 to enter and exit the pull wire groove 511. By arranging the guide rod 43 between the side frame 51 and the shaft side rotating wheel 42, the pull wire 40 led out by the shaft side rotating wheel 42 can be guided and smoothly enter the pull wire groove 511 on the side frame 51, which can prevent the pull wire 40 from being interfered and scratched by the surrounding structural members, thereby further improving the smoothness of the transmission of the pull wire 40. In order to prevent the mounting portion 31 from being scratched by the pull wire 40, a gap is provided on the end of the second guide crossbeam 13 corresponding to the path of the pull wire 40.
[0082] As can be seen from the above, the front sunshade curtain 1 of the present embodiment is provided with a front end rod 11 suitable for manual pulling or pushing at the end of the front curtain cloth 10. The front end rod 11 driven by external force can rotate the front shaft 12 through the front curtain cloth 10 or the pull wire 40, so that the front curtain cloth 10 is unfolded from the front shaft 12 to open or is rolled up to the front shaft 12 to close. The whole structure is compact and efficient, thereby providing a sunshade curtain structure scheme suitable for manual opening and closing.
