[0002] This application relates to the technical field of automotive sunroofs, and particularly to vehicles, roof glass assemblies, and their processing methods.
Background Art
[0003] With the development of the vehicle field, in order to ensure a wider field of view, the number of vehicle models choosing glass roofs is increasing. The larger the occupancy rate of the roof glass, the wider the field of view of the vehicle. However, in some scenarios, for example, in hot summer, sunlight directly enters through the roof glass, affecting the comfort of driving and riding in the vehicle, so roof sunshades have emerged. Optionally, the sunshade can be selectively deployed, and the sunshade usually has structures such as guide rails and can move smoothly along a specific direction. Also, to achieve the automatic opening and closing of the sunshade, it is necessary to arrange corresponding drive members, etc. Generally, to realize these functions, a large number of components need to be combined, which significantly occupies the space inside the vehicle and reduces the occupancy rate of the activity space of the passengers.

[0021] To make the above-mentioned objectives, features, and advantages of the present application clearer and easier to understand, specific embodiments of the present application will be described below in detail with reference to the accompanying drawings. The following description will include many specific details in order to provide a complete understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application; therefore, the present application is not limited by the specific embodiments disclosed below.
[0022] As shown in Figure 1, some embodiments of the present invention provide a roof glass assembly 10 including a roof glass 11, two guide rails 12, and two hollow tubes 13. Furthermore, in some embodiments, the roof glass assembly 10 further includes a sunshade 17 and two cables (not shown).
[0023] The two guide rails 12 included in the roof glass assembly 10 are both connected to the roof glass 11, and the two hollow tubes 13 are also both connected to the roof glass 11. The two guide rails 12 are positioned opposite each other with a gap between them, and the area between the two guide rails 12 is the area that is shielded when the sunshade 17 is deployed.
[0024] Each of the hollow tubes 13 has at least some of its segments arranged along the spacing direction of the two guide rails 12, and these segments are close to the same end of the two guide rails 12, with one end of each guide rail 12 close to these segments being the first end and the other end of the guide rail 12 being the second end. One end of one hollow tube 13 is positioned in the guiding direction of the first end of one guide rail 12, and one end of the other hollow tube 13 is positioned in the guiding direction of the first end of the other guide rail 12. Positioning in the guiding direction of the first end of the guide rail 12 means that an extension line extending from the first end along the guiding direction of the guide rail 12 passes through this position, so that a cable extending from the first end of the guide rail 12 can be smoothly inserted into the corresponding hollow tube 13, and the orientation of the cable after it moves from the guide rail 12 to the hollow tube 13 is determined by the hollow tube 13.
[0025] A guide passage is formed by the corresponding matching of one hollow tube 13 and one guide rail 12, and the cable is provided in each guide passage. One end of one cable is connected to one end of the movable side 171 of the sunshade 17, and the other end of the cable is connected to the other end of the movable side 171 of the sunshade 17. As the cable moves along the guide passage 122, the movable side 171 of the sunshade 17 slides along the guide direction of the guide rail 12, thereby allowing the sunshade 17 to switch between two states: unfolded and retracted.
[0026] Furthermore, as shown in Figures 1 to 5, each of the hollow tubes 13 passes through the drive member mounting position 111. The drive member mounting position 111 is used to mount a drive member 16, such as a motor. The cable, which is provided through the hollow tube 13, passes through the drive member mounting position 111 and engages with the drive member 16. When the drive member 16 is operated, it drives the cable, causing it to slide along its own path, in other words, the cable slides within the hollow tube 13 and the guide rail 12.
[0027] Each of the hollow tubes 13 is connected by injection molding to a molding 14 provided along the arrangement path of the hollow tube 13 and fixed to the roof glass 11. For example, the three components of the hollow tube 13, molding 14, and roof glass 11 may be connected by integral injection molding, or the hollow tube 13 may first be connected to the molding 14 by injection molding, and then the molding 14 may be bonded to the roof glass 11.
[0028] The area defined by the two guide rails 12 and the hollow tube 13 is the area covered when the sunshade 17 is deployed. Both ends of the movable side 171 of the sunshade 17 are inserted into the two guide rails 12 and are slidable within the two guide rails 12. Both ends of the movable side 171 of the sunshade 17 are connectable to a cable, which is provided through the hollow tube 13. When the drive member 16 is activated, it moves the cable along the hollow tube 13 and the guide rails 12, and can further control the opening and closing of the sunshade 17. The hollow tube 13 is connected by injection molding to a molding 14 provided along its own arrangement path and fixed to the roof glass 11, resulting in a small overall thickness for the roof glass assembly 10, a low space occupancy rate, and an improved occupancy rate of the occupants' activity space.
[0029] Specifically, in one embodiment, as shown in Figure 3, the hollow tube 13 and the molding 14 are connected by injection molding, eliminating the need to provide a separate cross member to fix the molding 14. The distance B between one end of each hollow tube 13 and the roof glass 11 is 6.5 mm or less in all cases, significantly reducing the thickness of the roof glass assembly 10. Since only the molding 14 exists between the hollow tube 13 and the roof glass 11, the thickness B of the molding 14 can be precisely controlled, and it is only necessary to precisely define the relative position between the hollow tube 13 and the roof glass 11 during injection molding, resulting in high operability.
[0030] More specifically, in some embodiments, the distance B between one end of each hollow tube 13 and the roof glass 11 is always between 2 mm and 6.5 mm. For example, the distance B between the end of the hollow tube 13 that forms a guide passage corresponding to the guide rail 12 and the roof glass is between 2 mm and 6.5 mm. If the distance B between the hollow tube 13 and the roof glass 11 is too small, there will be less molding material, which may lead to an uncertain fixation. If the distance B between the hollow tube 13 and the roof glass 11 is too large, the thickness of the roof glass assembly 10 will increase. Based on this, limiting the distance B to the above range allows for a balance between connection reliability and thickness requirements.
[0031] If a cross member is provided separately, and then guide members are further provided on the cross member to restrict the cable, the cable must be arranged along a predetermined path. In this case, the total thickness of the cross member and guide members must be 10 mm, which increases the overall thickness of the roof glass assembly. In this invention, the hollow tube 13 is connected to the molding 14 by injection molding, and the distance B between at least one end of the hollow tube 13 and the roof glass 11 is controlled within the above range. This not only lowers the height of the hollow tube 13, but also lowers the height of the guide rail 12 corresponding to the hollow tube 13.
[0032] As shown in Figure 3, in some embodiments, the two hollow tubes 13 are completely covered by the molding 14. In a cross-section perpendicular to the axial direction of the hollow tubes 13, the circle corresponding to the hollow tubes 13 is completely located within the molding 14.
[0033] As shown in Figure 4, in some other embodiments, two hollow tubes 13 are half covered by a molding 14. In a cross-section perpendicular to the axial direction of the hollow tube 13, the circle corresponding to the hollow tube 13 is partially located within the molding 14.
[0034] As shown in Figure 5, in some embodiments, one hollow tube 13 is completely covered by the molding 14, and the other hollow tube 13 is half covered by the molding 14.
[0035] In some embodiments, the coefficient of dynamic friction μ between the hollow tube 13 and the cable is 0.1 to 0.3, so that the cable slides smoothly inside the hollow tube 13, reducing noise when opening and closing the sunshade 17 and improving the sound quality of the vehicle.
[0036] As shown in Figure 3, in some embodiments, the inner diameter tolerance of the hollow tube 13 satisfies φA ± 0.1 mm. When the tolerance is met, the distance B between one end of the hollow tube 13 and the roof glass 11 is 2 mm to 6.5 mm.
[0037] More specifically, as shown in Figures 1 and 2, the drive member mounting position 111 is located between the two guide rails 12. Each of the hollow tubes 13 includes two straight pipe segments 132 abutted against both sides of the drive member mounting position 111, and the straight pipe segments 132 are arranged along the spacing direction of the two guide rails 12. The other end of each straight pipe segment 132, which is abutted against the drive member mounting position 111, is in communication with the curved pipe segment. The two curved pipe segments contained in each of the hollow pipes 13 are, respectively, a starting curved pipe segment 133 and an intermediate curved pipe segment 134, and the starting curved pipe segment 133 contained in one of the hollow pipes 13 and the intermediate curved pipe segment 134 contained in the other hollow pipe 13 are located on the same side of the drive member mounting position 111. One end of the starting curved pipe segment 133 that is not in communication with the straight pipe segment 132 is positioned in the guiding direction of one guide rail 12, and the other end of the starting curved pipe segment 133 that is not in communication with the straight pipe segment 132 is positioned in the guiding direction of the other guide rail 12. An extension pipe segment 135 is connected to one end of each of the two intermediate curved pipe segments 134 that is not in communication with the straight pipe segment 132, and both of the extension pipe segments 135 are arranged along the guiding direction of the guide rail 12, and the two guide rails 12 are located between the two extension pipe segments 135.
[0038] One hollow pipe 13 includes two straight pipe segments 132, one extension pipe segment 135, and two curved pipe segments, with one starting curved pipe segment 133, two straight pipe segments 132, one intermediate curved pipe segment 134, and one extension pipe segment 135 arranged in sequence, and then arranged along an L-shaped path after the four are connected.
[0039] The starting curved pipe segment 133 is positioned corresponding to the guide rail 12 so that the cable can transition from the guide rail 12 to the starting curved pipe segment 133. Specifically, as shown in Figures 9 and 10, the starting curved pipe segment 133 may be inserted into the guide passage 122 of the guide rail 12, or the starting curved pipe segment 133 and the guide rail 12 may be spaced apart. In the drawing shown in Figure 2, the straight pipe segment 132, the curved pipe segment, and the extension pipe segment 135 are all completely covered by the molding 14, so at the angle shown, except for the process clamp position 131 which is exposed outside the molding 14, all other parts of the hollow pipe 13 are covered by the molding 14 and cannot be observed.
[0040] The drive member 16 is connected to the molding 14 by injection molding in a manner similar to that of the hollow tube 13, and is further fixed to the drive member mounting position 111 on the roof glass 11.
[0041] Alternatively, as shown in Figures 1, 2, and 6, the drive member 16 is attached to the molding 14 by bolts. As shown in Figure 6, an insert (not shown) is provided in the molding 14, and a bolt (not shown) is threaded through the drive member into the insert, thereby fixing the drive member 16 to the molding.
[0042] Similarly, as shown in Figure 7, in one embodiment, the guide rail 12 is connected to the molding 14 by injection molding and fixed to the roof glass 11, with some of the molding material positioned between the guide rail 12 and the roof glass 11. As shown in Figure 8, in another embodiment, the guide rail 12 is bonded to the roof glass 11 with adhesive 18.
[0043] As shown in Figure 7, when the guide rail 12 is connected to the roof glass 11 by integral injection molding via the molding 14, the guide rail 12, together with the roof glass 11, the hollow tube 13, and the molding mold, etc., needs to form an injection molding space during the injection molding process. After the molding material is injected into the injection molding space, an overflow prevention member 15 can be provided between the guide rail 12 and the roof glass 11 to prevent the molding material from flowing out to the outside.
[0044] Specifically, in one embodiment, as shown in Figure 7, the overflow prevention member 15 is located on the side of the guide rail 12 away from the hollow tube 13. The molding material between the guide rail 12 and the roof glass 11 is stopped by the overflow prevention member 15 on the side closer to the hollow tube 13.
[0045] Furthermore, as shown in Figure 7, in some embodiments, a slide groove 121 is formed inside the guide rail 12, and the slide groove 121 has an opening along the guiding direction of the guide rail 12. This slide groove 121 can function as a guide passage 122, and a cable is provided passing through the slide groove 121, with both ends of the movable side 171 of the sunshade 17 located in the slide groove 121. Naturally, the slide groove 121 can also be used in other cases where a guiding function is required. One side wall of the slide groove 121 and the roof glass 11 are connected by integral injection molding via the molding 14, which is the upper side wall 123 of the guide rail 12, and an overflow prevention member 15 is provided between the portion of the upper side wall 123 where the opening is formed and the roof glass 11, and the molding 14 is located on the side of the overflow prevention member 15 away from this opening. The overflow prevention member 15 prevents the molding material from entering the slide groove 121 during injection molding by securing the molding material on the opposite side of the opening. Specifically, the overflow prevention member 15 may be made of urethane foam.
[0046] Furthermore, as shown in Figure 7, in some embodiments, the thickness F of the molding material in this portion located between the guide rail 12 and the roof glass 11 is 1 mm to 4 mm. This not only serves a connecting function, but also prevents the roof glass assembly 10 from becoming thicker due to the increased thickness of the molding material.
[0047] As shown in Figure 10, in some embodiments, a portion of the hollow tube 13 is inserted into the guide passage 122 within the guide rail 12. The insertion depth G of the hollow tube 13 is greater than 10 mm, which ensures that the two can fit together tightly. The concentricity error between the hollow tube 13 and the guide passage 122 is ±0.3 to prevent noise generation when the cable slides between the two.
[0048] Alternatively, in another embodiment, as shown in Figure 9, the hollow tube 13 and the guide rail 12 are spaced apart, and the gap between the hollow tube 13 and the guide rail 12 in the guiding direction of the guide rail 12 is 1 mm to 3 mm. In this way, even if there is a concentricity deviation between the hollow tube 13 and the guide passage 122 within the guide rail 12, the gap between them absorbs this deviation, thus preventing the generation of abnormal noise when the cable slides.
[0049] Furthermore, as shown in Figures 1 and 2, in some embodiments, the hollow tube 13 is provided with a plurality of process clamp positions 131, which are arranged sequentially at intervals along the arrangement path of the hollow tube 13, and the process clamp positions 131 of the hollow tube 13 are not covered by the molding 14.
[0050] As shown in Figure 11, the process clamp position 131 is for the clamping claws 20 to clamp, and when the molding 14 is injection molded, the orientation of the hollow tube 13 is determined by each clamping claw 20. For example, a mold for molding is provided with multiple clamping claws 20, which are spaced apart, and the arrangement path of the multiple clamping claws 20 is the arrangement path of the hollow tube 13. After the injection molding of the molding 14 is completed, the clamping claws 20 can be removed from the hollow tube 13, so that the parts clamped by the clamping claws 20 are not covered by the molding 14. When the clamping claws 20 clamp the hollow tube 13, the space between the clamping claws 20 and the hollow tube 13 may be an interference fit. In some cases, specifically, the interference fit E between the two is 0.2 mm to 0.5 mm.
[0051] As shown in Figure 3, in one embodiment, all areas of the hollow tube 13 other than the process clamp position 131 are completely covered by the molding 14.
[0052] Alternatively, in another embodiment, as shown in Figure 4, the area of the hollow tube 13 other than the process clamp position 131 is partially covered by the molding 14. Furthermore, to ensure that the hollow tube 13 is covered by the molding 14 without falling, the depth to which the hollow tube 13 is fitted into the molding 14 is greater than the radius of the hollow tube 13.
[0053] Furthermore, as shown in Figure 5, the areas of one hollow tube 13 other than the process clamp position 131 are half covered by the molding 14, and the areas of the other hollow tube 13 other than the process clamp position 131 are completely covered by the molding 14.
[0054] As shown in Figures 1 and 2, each of the straight pipe segment 132, the curved pipe segment, and the extension pipe segment 135 is provided with the process clamp position 131, thereby ensuring that the hollow pipe 13 is positioned according to the target path.
[0055] In one embodiment, both the straight pipe segment 132 and the extension pipe segment 135 have process clamp positions 131 that are 30 mm or less from the end of the curved pipe segment, thereby ensuring that the curved pipe segment is positioned at the target curvature angle.
[0056] The radius of curvature R at any point along the curved path of the curved pipe segment is 65 mm or more, thereby ensuring that the cable can slide smoothly within the curved pipe segment and that the cable's sliding is not hindered by an excessively large angle of change per unit length of the curved pipe segment.
[0057] In one embodiment, as shown in Figure 1, the fixed shaft 172 of the sunshade 17 is positioned along the spacing direction of the two guide rails 12, and the fixed shaft 172 is located at one end of the two guide rails 12 away from the first end, i.e., at the second end. The drive member 16 drives the cables by engaging with both of the two cables to slide along its own arrangement path.
[0058] When the sunshade 17 is rolled up, it is located at one end of the guide rail 12 away from the drive member 16, and when the sunshade 17 is extended, it shields the area enclosed by the two guide rails 12 and the hollow tube 13.
[0059] Furthermore, in some embodiments of the present application, a method for processing a roof glass assembly 10 is provided, wherein the roof glass assembly 10 is the above-mentioned roof glass assembly 10, and the processing method is As shown in Figure 11, the hollow tube 13 is pressed against the clamp claws 20 of the molding die, forming an injection molding space with the hollow tube 13, the molding die, and the roof glass 11. The process includes the steps of injecting molding material into the injection molding space, and after the molding material has solidified, forming the molding 14 of the roof glass assembly 10.
[0060] The clamp claws 20 fix the hollow tube 13 to the molding mold, thereby fixing the relative positions of the hollow tube 13, the molding mold, and the roof glass 11, and thus forming the injection molding space.
[0061] Furthermore, as shown in Figures 12 to 14, the processing method is The process further includes the step of embedding plugs 30 at the ends of each hollow tube 13 to prevent the molding material from entering the hollow tubes 13 before injecting the molding material into the injection molding space.
[0062] As shown in Figures 12 and 14, the hollow tube 13 is interrupted at the drive member mounting position 111, the relative positions of the cut openings of the two hollow tubes 13 at this point are fixed, and a plug 30 that closes the two openings is integrally molded, making it easy to attach and detach as it closes both openings simultaneously.
[0063] As shown in Figure 7, the processing method is The process includes providing an overflow prevention member 15 between the guide rail 12 and the roof glass 11, and forming the injection molding space using the overflow prevention member 15, the guide rail 12, the roof glass 11, the hollow tube 13, and the molding die.
[0064] In some other embodiments of the present application, a vehicle is provided which includes the roof glass assembly 10. The roof glass assembly 10 may also be a sunroof assembly, in other words, the roof glass 11 is a sunroof glass, and the sunroof glass in the vehicle is installed on the roof in a manner that allows it to be opened and closed.
[0065] Selectively, the roof glass 11 may be a fixed glass fixed to the roof, in which case the relative position between the roof glass 11 and the vehicle body is fixed.
