Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile parts, especially relates to a cord guide structure. BACKGROUND

[0002] With the gradual improvement of people's requirements for automobile configuration, in most vehicle models, the roof will be provided with a sunroof glass, and a window is formed in the automobile roof to allow light to pass through the sunroof glass and enter the vehicle. The sunroof glass not only improves the external appearance of the roof, 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 sunroof glass needs to be shaded, so a sunshade curtain is installed on the automobile roof corresponding to the window to allow the window to be closed or opened flexibly.

[0003] According to the conventional design, the existing sunshade curtain configuration 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 a three-box vehicle model, the rear of the roof usually has a downwardly inclined slope shape, which results in a smaller installation space at the rear of the roof, 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 sunroof glass, thereby failing to maximize the transparent area of the sunroof glass. For the case where the reel is arranged at the middle or front of the roof, the height of the reel itself and the structure of the cord outlet also need to occupy a large height space, thereby reducing the height space of the area near the reel in the passenger compartment, which limits the interior height of the vehicle and further fails to meet the space requirements of the head of the people 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. SUMMARY

[0006] Therefore, the utility model aims at providing a cord guide structure to improve the space conditions of the outer side of the cord in the unfolded state of the sunshade curtain.

[0007] To achieve the above purpose, the technical scheme of the utility model is as follows:

[0008] A cord guide structure, comprising a reel on which a cord is wound, and a guide beam arranged on the side of the reel from which the cord is drawn out.

[0009] The guide beam is arranged in parallel to the axis of the reel and extrudes the curtain fabric from the side of the curtain fabric opposite to the reel; the curtain fabric pulled out from the reel forms a relatively bent winding-off section and an unfolding section under the extrusion of the guide beam;

[0010] With the out-of-curtain point of the winding-off section on the reel as a reference plane a, and with the axis as a center plane b, under the guidance of the guide beam, the winding-off section extends obliquely relative to the reference plane a towards the center plane b, and the unfolding section is parallel to the center plane b.

[0011] Further, the out-of-curtain angle c between the winding-off section and the reference plane a is limited to 40° or less; and / or, the guide beam is located on the center plane b, and the unfolding section is located on the side of the center plane b opposite to the reference plane a.

[0012] Further, the guide beam comprises a main body and mounting portions separately arranged at two ends of the main body, the mounting portions are used for fixing the guide beam, and the main body is formed with guide portions used for extruding the curtain fabric.

[0013] Further, in the cross section of the main body, the guide portions are configured as curved surfaces protruding towards the curtain fabric.

[0014] Further, the main body comprises a bottom plate, a front side plate and a rear side plate integrally connected, the guide portions comprise a front guide portion formed on the front side plate and a rear guide portion formed on the rear side plate;

[0015] The front guide portion is located on the side of the rear guide portion away from the reel, and the front guide portion and the rear guide portion are staggered in the direction perpendicular to the reference plane a.

[0016] Further, the front side plate and the rear side plate are formed with a ventilation slot, and the ventilation slot makes the inner cavity of the main body communicate with the outside.

[0017] Compared with the prior art, the curtain fabric guiding structure has the following advantages:

[0018] The curtain fabric guiding structure changes the oblique state of the winding-off section of the curtain fabric by the guide beam, so that the unfolding section can be unfolded in parallel to the out-of-curtain direction, and the transition part between the winding-off section and the unfolding section is closer to the reel under the lifting action of the guide beam, so that the space on the side of the curtain fabric away from the reel is increased and more regular, thereby improving the space condition on the outside of the curtain fabric in the unfolded state of the sunshade curtain.

[0019] Furthermore, placing the guide beam in the center plane maximizes the space outside the unfolded section. Taking a car sunshade as an example, when the roller uses a bottom-out fabric release method, the fabric release point is located at the bottom of the roller. The guide beam lifts the fabric upwards, placing the entire unfolded section above the center plane, thus providing more spaciousness below the unfolded section and effectively improving headroom for passengers. By setting mounting parts at both ends of the guide beam's main body, the functional and mounting parts of the guide beam are effectively separated. This not only facilitates the installation and fixation of the guide beam but also avoids the influence of the guide beam's installation structure on the fabric. The guiding parts on the main body effectively compress and guide the fabric.

[0020] Another objective of this utility model is to provide an automobile roof, including a roof frame, a panoramic glass disposed on the roof frame, and a sunshade assembly for covering the panoramic glass; the sunshade assembly adopts the curtain guiding structure described in this utility model.

[0021] Furthermore, the roller is located in the middle of the canopy frame, the curtain exit direction is set towards the rear of the vehicle, the fabric exit point is located at the bottom of the roller, and the guide beam squeezes the curtain from below upwards.

[0022] Furthermore, the two ends of the guide beam are connected to the ceiling frame, and a boss is provided on the interior panel of the ceiling below the guide beam, which supports the main body of the guide beam.

[0023] Furthermore, the sunshade assembly includes a frame for guiding the curtain fabric out of the curtain, and a drive device for driving the curtain fabric to unfold and retract; the roller and the drive device are respectively located at the front and rear ends of the frame.

[0024] This invention provides a car roof with the technical advantages of the aforementioned curtain guide structure. Furthermore, by positioning the roller in the center of the car roof and extending the fabric towards the rear of the vehicle, this curtain guide structure ensures both a sufficiently large front-to-back dimension for the sunroof glass and adequate space in the passenger compartment below the center of the roof. When the roller extends downwards, the exit point is located at the bottom of the roller, and the guide beam lifts the curtain upwards, placing the entire unfolded section above the center plane. This provides more spaciousness below the unfolded section, effectively improving headroom for passengers. Attached Figure Description

[0044] The utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0045] Embodiment one

[0046] This embodiment relates to a kind of cloth guide structure, can improve the space condition of curtain cloth 1 outside in sunshade curtain deployment state;One exemplary structure is as shown in Figure 1 、 Figure 2and Figure 3 As shown.

[0047] Overall, the curtain guiding structure includes a roller 2 on which the curtain 1 is rolled, and a guide beam 3 located on the curtain exit side of the roller 2. The guide beam 3 is arranged parallel to the axis 20 of the roller 2, and the guide beam 3 presses the curtain 1 from the side of the curtain 1 opposite to the roller 2; under the pressure of the guide beam 3, the curtain 1 pulled out from the roller 2 forms a relatively bent exit section 11 and unfolding section 12.

[0048] The plane defined by the translation of the exit point 110 of the exit section 11 on the roll 2 along the exit curtain direction is the reference plane a, and the plane defined by the translation of the axis 20 along the exit curtain direction is the center plane b. Guided by the guide beam 3, the exit section 11 extends at an inclination relative to the reference plane a toward the center plane b, and the unfolding section 12 is parallel to the center plane b.

[0049] It should be noted that, based on the above-mentioned overall design concept, the technical solution of this utility model can adopt a variety of different specific implementation structures, forms, or configuration sequences. For example, the above-mentioned curtain guiding structure can be applied to the car roof or to the side window position of the vehicle. When the curtain guiding structure is used in the sunshade assembly of the car roof, the curtain 1 on the roller 2 can be in the form of top-out fabric or bottom-out fabric; the specific setting sequence and assembly method of the roller 2, guide beam 3, etc. on the sunshade assembly can also be flexibly adjusted. For the parts required for the implementation of the overall solution but not involved in the above overall setting, reasonable and flexible design can be made by referring to mature setting methods in the field and the actual situation during implementation. The specific implementation scheme described below in this embodiment is only one of the many solutions that can be formed by the above-mentioned combinations and variations. In actual implementation, those skilled in the art can make flexible adjustments and improvements based on the actual situation. Obviously, the many solutions that can be formed by the above-mentioned combinations and variations, as well as the specific implementation scheme of this embodiment, are all within the protection scope of this utility model.

[0050] To facilitate understanding and description of the solution, taking a vehicle roof as an example, for the case where a panoramic glass 60 is provided on the roof, a sunshade assembly is provided at the window position corresponding to the panoramic glass 60. In this embodiment, the curtain guide structure is located within this sunshade assembly. Furthermore, taking the case where the curtain 1 extends towards the rear of the vehicle as an example, the aforementioned curtain extension direction is... Figures 1 to 3 The direction indicated by T, i.e., the direction of the curtain exit, is exactly opposite to the X-direction of the vehicle. For example... Figure 3 and combined Figure 4As shown, the frame 5 of the sunshade curtain assembly can be fixed on the ceiling frame 6, and the frame 5 is provided with a guide groove, and the edge of the curtain cloth 1 can be guided to be arranged in the guide groove; the end of the curtain cloth 1 is fixed on the end rod 10, the two ends of the end rod 10 are guided to be arranged in the guide groove of the frame 5 on the corresponding side, and the end rod 10 is connected with the pull wire 100, the pull wire 100 is connected with the driving device 4 in transmission, under the driving of the driving device 4, the pull wire 100 can pull the end rod 10 to translate along the curtain-unfolding direction, and synchronously drive the reel 2 to rotate, so as to pull the curtain cloth 1 out of the reel 2 to unfold the curtain cloth 1, or wind the curtain cloth 1 on the reel 2 to fold the curtain cloth 1.

[0051] The specific structure of the guide beam 3 can be various. In the embodiment, as shown in Figure 5 and Figure 6 , the guide beam 3 includes a main body 30 and mounting portions 31 arranged at the two ends of the main body 30, the mounting portions 31 are used to fix the guide beam 3, and the main body 30 is formed with a guide portion used to press the curtain cloth 1. In the embodiment, a plurality of mounting holes 310 are arranged on the mounting portion 31, and the two ends of the guide beam 3 can be fixed on the corresponding frame 5 by penetrating the mounting holes 310 with bolts. By arranging the mounting portions 31 at the two ends of the main body 30 of the guide beam 3, the functional part and the mounting part of the guide beam 3 are effectively separated, which not only facilitates the mounting and fixing of the guide beam 3, but also avoids the influence of the mounting structure of the guide beam 3 on the curtain cloth 1. The guide portion on the main body 30 can well form the pressing and guiding of the curtain cloth 1.

[0052] Specifically, as shown in Figure 6 and Figure 7 , Figure 8 , in the cross section of the main body 30, the guide portion is designed as a curved surface protruding towards the curtain cloth 1. The guide portion is designed as a curved surface, which can form a good transition between the unwinding section 11 and the unfolding section 12, and reduce the damage of the friction between the guide beam 3 and the surface of the curtain cloth 1 to the curtain cloth 1.

[0053] Of course, the guide beam 3 can be made of solid structure or profile with closed cross section. Preferably, the main body 30 of the 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 bent relative to the bottom plate 300 and shaped to have convex curved surfaces for contacting the curtain 1, i.e. the guide portions mentioned above 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 winding shaft 2, 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 spaced apart in front and rear directions and staggered in up and down directions, which not only can well form the guide and transition of the curtain 1, 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 curtain 1 caused by continuous friction and overheating.

[0054] 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 curtain 1 and the guide beam 3 evenly distributed to the entire guide beam 3 through the inner cavity 306, which is more conducive to the transfer and dispersion of heat, thereby improving the situation of friction and overheating of the guide beam 3. Based on the structural features of the guide beam 3, the guide beam 3 can be processed by bending or extrusion forming process of plate material, and the end portions of the front side plate 301 and the rear side plate 302 are bent towards the inside of the 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 spacing the end portions of the front side plate 301 and the rear side plate 302.

[0055] As shown in Figure 7 and Figure 8 , by arranging the guide beam 3, the height of the unwinding section 12 of the curtain 1 can be raised as a whole, thereby providing more spacious space below (outside) the curtain 1. Compared with the case without the guide beam 3, the unwinding section 12 of the curtain 1 can be raised by a height H as shown in Figure 8 .

[0056] Specifically, by setting the guide beam 3, a fabric exit angle c is formed between the unwinding section 11 and the reference plane a. Preferably, the fabric exit angle c is limited to below 40°. Because as the length of the fabric 1 is pulled out changes, the distance between the fabric exit point 110 of the unwinding section 11 on the roller 2 and the axis 20 of the roller 2 changes, meaning the position of the reference plane a shifts vertically. Therefore, the fabric exit angle c between the unwinding section 11 and the reference plane a changes as the fabric 1 is pulled out. By reasonably setting the distance between the guide beam 3 and the roller 2, and the height of the guide beam 3 in the direction perpendicular to the reference plane a, the fabric exit angle c can be limited to a reasonable range. Controlling the fabric exit angle c to below 40° ensures that the transition angle between the unwinding section 11 and the unfolding section 12 is always above 140°, effectively reducing the contact area and pressure between the fabric 1 and the guide beam 3, thereby reducing the resistance of the fabric 1 during the pulling out and retracting process.

[0057] Furthermore, preferably, in this embodiment, the guide beam 3 is disposed on the central plane b, that is, the unfolding section 12 is raised above the central plane b, meaning that the unfolding section 12 is located on the side of the central plane b opposite to the reference plane a. Distributing the guide beam 3 on the central plane b maximizes the space outside the unfolding section 12. Taking a sunshade in a vehicle roof as an example, when the roller 2 uses a bottom-out fabric method, the fabric outlet 110 is located at the bottom of the roller 2. The guide beam 3 raises the curtain 1 upwards, allowing the entire unfolding section 12 to be located above the central plane b, thus providing more spacious space below the unfolding section 12 and effectively improving headroom conditions for passengers.

[0058] In summary, the curtain guiding structure of this embodiment uses the guide beam 3 to change the inclination state of the roll-out section 11 of the curtain 1, so that the unfolding section 12 can unfold parallel to the curtain exit direction. The transition part between the roll-out section 11 and the unfolding section 12 is closer to the roller 2 under the lifting action of the guide beam 3, so that the space on the outer side of the curtain 1 facing away from the roller 2 is increased and more regular, thereby improving the space conditions on the outside of the curtain 1 when the sunshade is unfolded.

[0059] Example 2

[0060] This embodiment relates to a car roof, including a roof frame 6, a panoramic glass 60 disposed on the roof frame 6, and a sunshade assembly for covering the panoramic glass 60; and the sunshade assembly adopts the curtain guide structure provided in Embodiment 1.

[0061] Specifically, in this embodiment, as Figure 9 As shown, the roller 2 is located in the middle of the ceiling frame 6. Figure 9Only the middle and rear part of the roof frame 6 is shown, and the spool 2 is located at the front end of the roof frame 6 in the figure, and the curtain fabric 1 on the spool 2 is arranged to be drawn out towards the rear of the vehicle. At the same time, as shown in Figure 7 and Figure 8 the out-curtain point 110 of the curtain fabric 1 is located at the bottom of the spool 2. In this way, the guide beam 3 will press the curtain fabric 1 upwards from the lower side of the curtain fabric 1 to lift the curtain fabric 1 and increase the height of the curtain fabric 1.

[0062] Of course, in addition to the curtain fabric 1 and the spool 2, the sunshade curtain assembly also includes the frame 5 and the driving device 4. The frame 5 is mainly used to guide the curtain fabric 1 to be drawn out, and the driving device 4 is used to drive the curtain fabric 1 to be unfolded and rolled up. The spool 2 and the driving device 4 are respectively arranged at the front and rear ends of the frame 5. The two ends of the spool 2 are respectively fixed to the corresponding side of the frame 5 through the mounting seat 21 and are fixed to the roof frame 6. The mounting portions 31 at the two ends of the guide beam 3 are respectively fixed to the corresponding side of the frame 5 and are fixed to the roof frame 6. In addition, in order to ensure the stability of the guide beam 3, based on the fact that the roof lining is fixed below the roof frame 6, a boss structure can be arranged on the roof lining. When the guide beam 3 is connected to the roof frame 6 at the two ends, the boss arranged on the roof lining is in abutment with the bottom of the main body 30 of the guide beam 3, thereby forming effective support for the main body 30 of the guide beam 3.

[0063] At the same time, in the embodiment, the middle and front end of the frame 5 are also fixed to the roof frame 6. The frame 5 is provided with a guide groove, and the edge portion of the curtain fabric 1 is guided to be arranged in the guide groove. The end portion of the curtain fabric 1 is fixed to the end rod 10, and the two ends of the end rod 10 are guided to be arranged in the guide groove of the corresponding side of the frame 5 and are connected to the pull wire 100. The pull wire 100 is connected in transmission with the driving device 4. Under the driving of the driving device 4, the pull wire 100 can pull the end rod 10 to translate along the out-curtain direction and synchronously drive the spool 2 to rotate. Through such transmission arrangement, the curtain fabric 1 can be pulled out of the spool 2 to unfold the curtain fabric 1, or the curtain fabric 1 can be rolled up on the spool 2 to roll up the curtain fabric 1.

[0064] In view of the poor space condition of the rear part of the automobile roof, especially in the three-door sedan model, the rear part of the automobile roof is arranged to be inclined downward, so that the rear part of the automobile roof is very limited in height space, and it is difficult to provide good conditions for the installation and arrangement of the winding shaft 2. Therefore, if the winding shaft 2 is arranged at the rear part of the automobile roof, it needs to be moved forward as much as possible, so that the size of the sunroof glass 60 also needs to be reduced. By arranging the winding shaft 2 in the middle part of the automobile roof and adopting the form of out-arrangement towards the rear of the vehicle, by adopting the curtain fabric guiding structure of the utility model, while ensuring that the sunroof glass 60 has a large enough front and rear size, the space size in the space below the middle part of the automobile roof is also ensured. Specifically, when the winding shaft 2 adopts the out-arrangement mode, the out-arrangement point 110 is located at the bottom of the winding shaft 2, the guide beam 3 lifts the curtain fabric 1 upwards, so that the entire unfolding section 12 is located above the center plane b, thereby providing more spacious space below the unfolding section 12, and effectively improving the head space condition of the passengers.

[0065] By arranging the winding shaft 2 at the middle part of the automobile roof, which is just located at the rear part of the front row seat back, by adopting the curtain fabric guiding structure of the utility model, the problems of insufficient head space of the front row and rear row passengers in the passenger compartment and insufficient large transparent area are solved. For the rear passengers, the above-mentioned sunshade curtain assembly can form a good shading effect on the window located at the middle and rear part of the automobile roof. At the same time, the front part of the automobile roof can be additionally provided with a sunshade curtain for shading the window opened in the front part of the automobile roof. For the main window in the middle and rear part of the automobile roof, the winding shaft 2 and the driving device 4 in the sunshade curtain assembly are arranged separately in front and rear, so as to maximize the head space of the rear passengers. The transmission structure of the pull wire 100 between the driving device 4 and the winding shaft 2 can design the frame 5 of the sunshade curtain assembly as a narrow strip with a very small height size, so as to further save the head space in the vehicle.

[0066] The above-mentioned is only the preferred embodiment of the utility model, and the detailed configuration explanation, specific structure setting form example, or assembly connection mode expression, etc. are all for the need of full disclosure, so as to better implement the utility model for the technical personnel in the field, and not to limit the protection scope of the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
