Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to sunshade devices for vehicles. Background Technology

[0002] Some vehicles are equipped with sunroofs, or even panoramic sunroofs, to increase the amount of light entering the vehicle. However, in environments with strong sunlight, it is necessary to shade the sunroof to reduce the amount of light entering the vehicle.

[0003] In some vehicles, a sunshade system is installed on the roof panel. The sunshade system consists of a curtain and a roller. The curtain is connected to the roller. When the sunroof is not needed, the curtain is rolled up onto the roller. When the sunroof needs to be covered, the curtain is unrolled from the roller.

[0004] Typically, curtains also have side strips to keep the curtain taut when it is unrolled. These side strips are usually bonded to the roller. When the curtain is unrolled, the side strips are subjected to tension along the unrolling direction. This can cause the side strips to shift from their bonded position on the roller after multiple unrolling cycles, resulting in wrinkles in the curtain. Utility Model Content

[0010] In one embodiment, the fixing part is offset from the first fixing hole and the second fixing hole.

[0011] In one embodiment, the first mounting part is inserted into the first fixing hole and is fixedly clamped between the fixing member and the edge of the first fixing hole.

[0012] In one embodiment, the curtain includes a fixing part fixedly connected to a roller; and a second mounting part located to the side of the fixing part and separated from the fixing part along a second direction parallel to the roller; the first mounting part and the second mounting part are stacked; wherein the first mounting part and the second mounting part are inserted together into a first fixing hole and clamped between the fixing member and the edge of the first fixing hole.

[0013] In one embodiment, the second mounting portion separates the first mounting portion from the edge of the first fixing hole.

[0014] In one embodiment, the fastener includes a clamping section with ribs formed on its circumferential side; after the fastener is inserted into the first fixing hole, the first mounting portion is clamped between the circumferential side of the clamping section and the edge of the first fixing hole.

[0015] In one embodiment, after the fastener is inserted into the first fixing hole, the end face of the clamping segment is flush with the circumferential surface of the reel.

[0016] In one embodiment, the fastener further includes a guide section extending from the clamping section, the guide section being adapted to pass through the first fixing hole into the interior of the spool, and the cross-sectional dimensions of the guide section gradually decreasing in the direction away from the clamping section.

[0017] In one embodiment, at least a portion of the first mounting portion is fixedly connected to the guide section and / or the clamping section.

[0018] In one embodiment, the sunshade device further includes a guide rail extending in a first direction; the side strip is adapted to slidably engage with the guide rail.

[0019] In one embodiment, the curtain has a moving portion away from the roller; the sunshade device further includes two pulleys, respectively mounted at two ends of the roller; two pull cords adapted to be wound up or released on the two pulleys respectively, both pull cords being connected to the moving portion of the curtain; and a drive member connected to one end of the roller; wherein the drive member is adapted to drive the roller to rotate, the two pulleys rotating synchronously with the roller, so that the curtain is wound up onto the roller and the two pull cords are released from the two pulleys respectively, or the curtain is released from the roller and unfolded, and the two pull cords are wound up onto the two pulleys respectively.

[0020] The beneficial effects of this application are as follows: According to the sunshade device for vehicles of this application, the first mounting portion of the side strip is fixedly connected to the roller via a fastener. Thus, when the curtain is unfolded, even if the side strip is subjected to tension along a first direction, the mounting position of the first mounting portion of the side strip on the roller will not move. This helps to prevent wrinkles in the curtain. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] Figure 1 A vehicle 1 according to one embodiment of this application is schematically shown. Figure 1 As shown, vehicle 1 includes a vehicle roof panel 12. A sunroof opening 11 is provided on the vehicle roof panel 12, and a sunroof glass (not shown) is installed at the sunroof opening 11. To cover the sunroof glass when needed, a sunshade device 2 (hereinafter referred to as sunshade device 2) for the vehicle is also installed at the sunroof opening 11. In some vehicles, the vehicle roof panel may also be made of glass (i.e., the vehicle roof panel is a glass sunroof). In this case, the sunshade device 2 is installed on the glass sunroof.

[0036] The following describes the sunshade device 2.

[0037] Reference Figure 2 and Figure 3 The sunshade device 2 mainly includes two roughly parallel guide rails (i.e., the first guide rail 51 and the second guide rail 52), a drive unit 201, a roller 3, two rope wheels (i.e., the first rope wheel 31a and the second rope wheel 31b) installed at the two ends of the roller 3, two pull ropes (i.e., the first pull rope 32a and the second pull rope 32b) and a curtain 6.

[0038] The curtain fabric 6 is generally rectangular and has two longitudinal edges (i.e., a first longitudinal edge 601a and a second longitudinal edge 601b) extending along a first direction D1 (the first direction D1 is generally parallel to the length direction of the curtain fabric 6) and a fixed portion 602a and a movable portion 602b extending along a second direction D2 (the second direction D2 is generally parallel to the width direction of the curtain fabric 6). The fixed portion 602a and the movable portion 602b are opposite each other along the first direction D1. In one embodiment, a pull rod 61 is provided at the movable portion 602b of the curtain fabric 6.

[0039] The first guide rail 51 and the second guide rail 52 extend generally along the first direction D1 and are located on both sides of the curtain 6 along the second direction D2. For example, the first guide rail 51 is adjacent to the first longitudinal edge 601a of the curtain 6, and the second guide rail 52 is adjacent to the second longitudinal edge 601b of the curtain 6. In this way, the curtain 6 can reciprocate along the first direction D1 under the guidance of the two guide rails.

[0040] The roller 3 is positioned between the first guide rail 51 and the second guide rail 52. For example, the roller 3 extends generally along the second direction D2. In one embodiment, the roller 3 is a hollow tube, which helps to reduce its weight. The curtain 6 is supported on the roller 3, and the fixing part 602a of the curtain 6 is fixedly connected to the roller 3 to prevent the curtain 6 from falling off the roller 3. In one embodiment, the fixing part of the curtain is bonded to the roller with an adhesive. Of course, depending on the actual situation, the fixing part of the curtain can also be fixedly connected to the roller in other ways, which will not be elaborated here. The moving part 602b of the curtain 6 is away from the roller 3.

[0041] The drive unit 201 is connected to one end of the reel 3 to drive the reel 3 to rotate, and the first rope pulley 31a and the second rope pulley 31b rotate synchronously with the reel 3 under the drive of the reel 3. In one embodiment, the drive unit 201 can be a motor.

[0042] The sunshade device 2 also includes two pulleys (i.e., a first pulley 33a and a second pulley 33b). The two pulleys are arranged on both sides of the curtain fabric 6 along the second direction D2. For example, the two pulleys are respectively arranged on two guide rails.

[0043] The first pull rope 32a is connected to the first end of the pull rod 61 and, after being redirected by the first pulley 33a, is connected to the first rope wheel 31a. The second pull rope 32b is connected to the second end of the pull rod 61 and, after being redirected by the second pulley 33b, is connected to the second rope wheel 32b.

[0044] When the drive unit 201 drives the roller 3 to rotate, for example, clockwise, the first pull cord 32a and the second pull cord 32b move backward along the first direction D1 (i.e., in the direction towards the roller 3 along the first direction D1) and are respectively wound onto the first rope pulley 31a and the second rope pulley 31b. The moving part 602b of the curtain 6 and the pull rod 61 are pulled by the two pull cords and move forward along the first direction D1 (i.e., away from the roller 3 along the first direction D1) away from the roller 3, so that the curtain 6 is released from the roller 3 and unfolded to cover the sunroof glass.

[0045] When the drive unit 201 drives the roller 3 to rotate, for example, counterclockwise, the curtain 6 is gradually drawn back onto the roller 3 (the moving part 602b of the curtain 6 and the pull rod 61 move backward toward the roller 3 along the first direction D1), thus revealing the window glass. The first pull cord 32a and the second pull cord 32b are released from the first pulley 31a and the second pulley 31b, respectively, and move forward along the first direction D1.

[0046] For example Figure 3 As shown, a first side strip 71 is provided at the first longitudinal edge 601a of the curtain fabric 6, and a second side strip 72 is provided at the second longitudinal edge 601b. Both side strips extend along the first direction D1. The two side strips are arranged in the same way. For simplicity, the technical solution of this application will be described below only by referring to the first side strip 71 and the corresponding first longitudinal edge 601a.

[0047] like Figure 4 As shown, in the sunshade device 2, the first side strip 71 is also slidably engaged with the corresponding first guide rail 51. For example, the first guide rail 51 is constructed with a sliding groove 511 extending along a first direction D1, and the first side strip 71 is slidably engaged into the sliding groove 511. During the movement of the curtain 6, the first side strip 71 slides along the first guide rail 51, which helps to reduce the movement resistance of the curtain 6. In addition, during the movement of the curtain 6, the first side strip 71 and the second side strip 72 also tension the curtain 6 along a second direction D2 to prevent wrinkles from forming in the curtain 6. It should be understood that the first side strip 71 and the second side strip 72 also have appropriate flexibility so that they can roll up and unroll with the curtain 6.

[0048] It should be understood that the first side strip 71 is also fixedly connected to the roller 3. Thus, during the winding and unwinding of the curtain 6, the first side strip 71 can withstand the tension along the first direction D1. The connection structure between the first side strip and the roller will be described below.

[0049] A first embodiment of the connection structure between the first side strip and the scroll.

[0050] Reference Figure 5 and Figure 6The roller 3 has a first fixing hole 311 on its circumferential wall. The first side strip 71 has a first mounting portion 711 corresponding to the first fixing hole 311. The sunshade device 2 also includes a fastener 4. The fastener 4 can be fixedly installed in the first fixing hole 311 and fix the first mounting portion 711 to the roller 3. For example, a second fixing hole 712 is provided in the first mounting portion 711. After the curtain 6 (and the first side strip 71) are installed on the roller 3, the second fixing hole 712 is aligned with the first fixing hole 311. The fastener 4 is fixedly installed in the second fixing hole 712 and the first fixing hole 311, thereby fixing the first mounting portion 711 to the roller 3. In this case, the fastener 4 can be implemented as a screw. It should be understood that, Figure 5 In the image, to make the first side strip and the curtain fabric clearer, part of the first side strip is not depicted as being connected to the curtain fabric. In reality, the first side strip and the curtain fabric are connected together.

[0051] During the winding and unwinding of the curtain 6, even if the first side strip 71 is subjected to tension along the first direction D1, the first mounting portion 711 will not move relative to the roller 3 because it is fixed by the fastener 4. In other words, the mounting position of the first mounting portion 711 on the roller 3 will not move. The same applies to the second side strip 72. In this way, the first side strip 71 and the second side strip 72 move synchronously with the curtain 6, which helps to prevent wrinkles from forming in the curtain 6.

[0052] In one embodiment, the fastener 4 is a countersunk screw. After the countersunk screw is installed into the first mounting hole 311, the screw head is almost flush with the first mounting portion 711. Thus, when the curtain 6 is rolled onto the roller 3, the countersunk screw will not substantially lift the spirally stacked first side strip 71 (and the corresponding portion of the curtain 6), and the roll formed by the curtain 6 will not produce a bulge, which helps to improve the quality of the sunshade device 2.

[0053] In one embodiment, at least a portion of the first mounting portion 711 is bonded to the roller 3. This provides a more secure connection between the first mounting portion 711 and the roller 3, helping to prevent misalignment of the first mounting portion 711 on the roller 3. Furthermore, when installing the curtain fabric 6 onto the roller 3, the fixing portion 602a of the curtain fabric 6 and the first mounting portion 711 of the first side strip 71 can be bonded to the roller 3 firstly, and the second fixing hole 712 aligned with the first fixing hole 311. When installing the fastener 4, the first mounting portion 711 will not move relative to the roller 3, and the second fixing hole 712 will always remain aligned with the first fixing hole 311, facilitating the installation of the fastener 4.

[0054] In one embodiment, the fixing portion 602a of the curtain 6 is offset from the first fixing hole 311 and the second fixing hole 712. In other words, the fastener 4 is not fixedly connected to the fixing portion 602a of the curtain 6. This eliminates the need to provide fixing holes for the fastener 4 on the fixing portion 602a of the curtain 6. When installing the fastener 4, only the first fixing hole 311 and the second fixing hole 712 need to be aligned, without considering the position of the fixing portion 602a of the curtain 6, which further facilitates the installation of the fastener 4. Of course, depending on the actual situation, a third fixing hole can also be provided for the fastener on the fixing portion of the curtain. The fastener passes through the first fixing hole, the second fixing hole, and the third fixing hole to fix the fixing portion of the curtain and the first mounting portion of the first side strip to the roller.

[0055] A second embodiment of the connection structure between the first side strip and the scroll.

[0056] The second embodiment of the connection structure between the first edge strip and the scroll is similar to the first embodiment of the connection structure. For simplicity, only the differences between the two will be described below.

[0057] like Figure 10 As shown, the curtain 6 includes a fixing part 602a (as described above) that can be fixedly connected to the winding 3, and also includes two second mounting parts 603 ( Figure 10 Only one second mounting portion is shown schematically. The two second mounting portions 603 are located on both sides of the fixing portion 602a along the second direction D2 and are separate from the fixing portion 602a. From the perspective of the curtain fabric 6 as a whole, the two second mounting portions 603 are part of the two longitudinal edges of the curtain fabric 6.

[0058] After the first side strip 71 is attached to the first longitudinal edge 601a of the curtain fabric 6, the first mounting portion 711 of the first side strip 71 and the second mounting portion 603 of the curtain fabric 6 are overlapped. In one embodiment, the first mounting portion and the second mounting portion are also sewn together.

[0059] like Figure 7 As shown, the first mounting portion 711 of the first side strip 71 and the second mounting portion 603 of the curtain 6 are inserted together into the first fixing hole 311. The fastener 4 is also inserted into the first fixing hole 311, and the first mounting portion 711 and the second mounting portion 603 are fixedly clamped between the fastener 4 and the edge of the first fixing hole 311 (i.e., the first mounting portion 711 and the second mounting portion 603 are fixedly installed in the first fixing hole 311). Thus, the first mounting portion 711 of the first side strip 71 is fixedly connected to the roller 3. During the winding and unwinding of the curtain 6, even if the first side strip 71 is subjected to tension along the first direction D1, the mounting position of the first mounting portion 711 on the roller 3 will not shift. It should be understood that, Figure 7In the image, to make the first side strip and the curtain fabric clearer, part of the first side strip is not depicted as being connected to the curtain fabric. In reality, the first side strip and the curtain fabric are connected together.

[0060] Furthermore, the second mounting portion 603 of the curtain fabric 6, being a fabric, possesses good flexibility and strength. When the first mounting portion 711 and the second mounting portion 603 are clamped together and installed within the first fixing hole 311, the second mounting portion 603 separates the first mounting portion 711 from the edge of the first fixing hole 311. In this way, the second mounting portion 603 protects the first mounting portion 711, preventing it from being cut off by the edge of the first fixing hole 311.

[0061] In some embodiments, the curtain fabric may not have a second mounting portion. In this case, only the first mounting portion of the first side strip is inserted into the first fixing hole. After the fastener is inserted into the first fixing hole, the first mounting portion is fixedly clamped between the fastener and the edge of the first fixing hole, thereby achieving a fixed connection between the first mounting portion of the first side strip and the roller.

[0062] Reference Figure 8 and Figure 9 The first fixing hole 311 is generally rectangular. The dimension of the first fixing hole 311 along the second direction D2 is greater than or equal to the dimension of the first mounting portion 711 (and the second mounting portion 603) along the second direction D2. The fastener 4 includes a clamping section 41. The clamping section 41 is a cuboid shape that generally matches the shape of the first fixing hole 311. In this way, the first mounting portion 711 and the second mounting portion 603 can be smoothly inserted into the first fixing hole 311. After the fastener 4 is inserted into the first fixing hole 311, the first mounting portion 711 and the second mounting portion 603 are smoothly clamped between the circumferential side of the clamping section 41 and the edge of the first fixing hole 311. This also helps to prevent wrinkles from forming on the first side strip 71 and the curtain fabric 6.

[0063] like Figure 9 As shown, the clamping section 41 has multiple protruding ribs 411 on its circumferential side surface. These protruding ribs 411 help to clamp the first mounting part 711 and the second mounting part 603 more firmly, thereby making the first mounting part 711 more stably installed in the first fixing hole 311.

[0064] Reference Figure 7 After the fastener 4 is inserted into the first fixing hole 311, the end face 412 of the clamping section 41 is roughly flush with the circumferential surface of the roller 3. In this way, when the curtain 6 is rolled onto the roller 3, the roll formed by the curtain 6 will not or will not produce any bulges, which helps to improve the quality of the sunshade device 2.

[0065] For example Figure 9As shown, the fastener 4 also includes a guide section 42 extending from the clamping section 41. When the fastener 4 is inserted into the first fixing hole 311, the guide section 42 passes through the first fixing hole 311 and enters the interior of the spool 3. In one embodiment, the cross-sectional dimension of the guide section 42 gradually decreases in the direction away from the clamping section 41. For example, the guide section 42 is generally pyramidal in shape. This guide section 42 guides the fastener 4 into the first fixing hole 311, making the installation operation of the fastener 4 easier.

[0066] The third embodiment of the connection structure between the first side strip and the scroll.

[0067] The third embodiment of the connection structure between the first side strip and the scroll is similar to the second embodiment of the connection structure. For simplicity, only the differences between the two will be described below.

[0068] like Figure 11 As shown, the curtain fabric 6 does not have the second mounting part described above. Only the first mounting part 711 of the first side strip 71 is inserted into the first fixing hole 311 and is fixedly clamped between the fixing member 4 and the edge of the first fixing hole 311.

[0069] At least a portion of the first mounting portion 711 is also fixedly connected to the guide section 42 of the fastener 4. This helps to further prevent the mounting position of the first mounting portion 711 on the reel 3 from shifting. In other embodiments, at least a portion of the first mounting portion may also be fixedly connected to the clamping section of the fastener, which will not be described in detail here.

[0070] In one embodiment, a clamping groove 421 is provided on the guide segment 42, and the end of the first mounting portion 711 is fixedly clamped within the clamping groove 421. Additionally, at least a portion of the first mounting portion 711 may be wound around the guide segment 42. Thus, the first mounting portion 711 is fixedly connected to the guide segment 42 (or the fastener 4). In some embodiments, an adhesive may also be used to bond the first mounting portion to the guide segment (or the fastener) for a more stable connection.

[0071] In some embodiments, the curtain fabric may also have a second mounting portion. In this way, the first and second mounting portions are inserted together into the first fixing hole and are fixedly connected to the clamping section and / or guide section. Further details are omitted here.

[0072] The above description is merely an embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this application should be included within the scope of the claims of this application.
