The pressure roller is mounted on the support shaft and corresponds to a support rod. The pressure roller is adapted to press the main body section of the support rod.

[0013] In one embodiment, the pressure roller rotates in the same direction as the first reel.

[0014] In one embodiment, the rotational speed of the pressure roller is greater than the rotational speed of the first reel.

[0015] In one embodiment, the pressing component further includes a transmission component, through which the first motor drives the bearing shaft to rotate.

[0016] In one embodiment, there are multiple support rods, and the multiple support rods extend parallel to each other.

[0017] In one embodiment, the second mounting portion of the curtain is provided with a pull rod extending along a first direction. The moving end of the support rod is connected to the pull rod.

[0018] In one embodiment, at least a portion of the pull rod is adapted to contact a window.

[0019] In one embodiment, the lever has a protrusion facing the window, the protrusion being adapted to slidably contact the window.

[0020] In one embodiment, the curtain fabric has two side strips that extend parallel to each other in a second direction and are spaced apart in a first direction. The sunshade device also includes two tensioning assemblies corresponding to the two side strips, the two tensioning assemblies being spaced apart in the first direction and the two side strips being positioned between the two tensioning assemblies. Each side strip is slidably engaged with its corresponding tensioning assembly, and the two side strips are constrained apart from each other by the two tensioning assemblies in the first direction.

[0021] In one embodiment, the two side strips have free portions facing each other along a first direction, each free portion being separate from the fabric. Each tensioning assembly includes a mounting plate and a tensioning frame. The mounting plate is disposed along the first direction on a side opposite to the free portion of the corresponding side strip. The tensioning frame extends along the first direction from the mounting plate toward the free portion of the corresponding side strip and slidably engages with the free portion.

[0022] In one embodiment, the tensioning frame includes a tensioning plate and a pressing plate. The tensioning plate is located between the free portion and the curtain fabric. The pressing plate is located to the side of the tensioning plate along a second direction. The pressing plate is also located on the side of the respective edge strip opposite to the curtain fabric and is adapted to press the edge strip.

[0023] In one embodiment, a mounting sleeve is provided on the curtain, and at least a portion of the support rod is inserted into the mounting sleeve.

[0024] In one embodiment, the curtain fabric has a first mounting portion and a second mounting portion opposite to each other along a second direction, the first mounting portion being connected to a first roller. The support rod includes a mounting end, a moving end, and a main body section located between the mounting end and the moving end. The mounting end is connected to the first roller, the moving end is connected to the second mounting portion of the curtain fabric, and the main body section is inserted into a mounting sleeve and adapted to move relative to the mounting sleeve.

[0025] In one embodiment, the curtain has a first surface and a second surface opposite to each other; the first surface faces the window and is coated with a light-blocking coating.

[0026] A second aspect of this application discloses a sunshade system for vehicle windows. The sunshade system includes a mounting bracket and a sunshade assembly for vehicle windows as described above. The sunshade assembly is mounted within the mounting bracket.

[0027] In one embodiment, the mounting bracket is implemented as a dashboard device.

Detailed Implementation

[0051] 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.

[0052] Figure 1 A portion of a vehicle 1 according to one embodiment of this application is schematically shown. Figure 1 As shown, the front of vehicle 1 is provided with a windshield 11 (the windshield is a window of the vehicle) and a sunshade system 12 adjacent to the windshield 11. (Refer to...) Figure 1 and Figure 2 The sunshade system 12 includes an instrument panel unit 121 and a sunshade device 123 installed within the instrument panel unit 121. When the curtain assembly 203 of the sunshade device 123 (described below) is deployed, it obstructs the windshield 11 to prevent direct sunlight from entering the vehicle's interior. It should be understood that the sunshade device can also be installed at the rear window of the vehicle (which is also a window of the vehicle) using appropriate mounting brackets (not shown in the figures), which will not be elaborated upon here.

[0053] Curtain assembly 203 includes curtain 21 (such as...) Figure 3 (As shown). The curtain 21 has a first surface and a second surface that are opposite to each other. When the curtain 21 is unfolded, the first surface faces the windshield 11 and is coated with a light-blocking coating, while the second surface faces the interior of the vehicle. This provides better sun shading for the curtain 21 (or curtain assembly 203), and the light-blocking coating protects the curtain 21, helping to extend its service life. Some vehicles are also equipped with a projection device (not shown), which can also be used as a screen when the curtain is unfolded. For example, the projection device projects onto the second surface of the curtain. The sunshade assembly 123 will now be described.

[0054] The first embodiment of the sunshade curtain device.

[0055] Reference Figure 3 and Figure 4a The sunshade device 123 includes a first motor 204, a first roller 201, a second roller 202, and a curtain assembly 203. The sunshade device 123 also has a base 206. The second roller 202 is rotatably mounted on the base 206. Additionally, as... Figure 6a and Figure 6b As shown, the sunshade device 123 also includes two supports 208 and two pressure caps 205. The first roller 201 and the bearing shaft 241 of the pressing assembly 24 (described below) are rotatably mounted on the two supports 208, and the two pressure caps 205 are respectively mounted on the two supports 208 and constrain the first roller 201 and the bearing shaft 241. The first motor 204 is mounted on one support 208. In this way, the first roller 201, the pressing assembly 24 and the first motor 204 form an integral assembly and are mounted on the base 206 via the two supports 208.

[0056] The first reel 201 extends along a first direction D1. For example, the first direction D1 generally corresponds to the width direction of the vehicle.

[0057] The first motor 204 is connected to the first spool 201 to drive the first spool 201 to rotate.

[0058] The second reel 202 is arranged side by side with the first reel 201. For example, the second reel 202 also extends generally along the first direction D1 (i.e., the first reel 201 and the second reel 202 are generally parallel), and the first reel 201 is located between the second reel 202 and the windshield 11. Of course, the second reel can also be bent into a suitable arc shape to match the shape of the instrument panel assembly.

[0059] In one embodiment, such as Figure 4b As shown, the second reel 202 includes a fixedly mounted spindle 251, a sleeve 252 sleeved on the spindle 251, and a drive spring 253 disposed within the sleeve 252. The two ends of the drive spring 253 engage with the spindle 251 and the sleeve 252, respectively. The sleeve 252 is rotatable relative to the spindle 251. In one embodiment, the sleeve is integral.

[0060] In one embodiment, as well as Figure 4b As shown, the second reel 202 has end pieces 254 at each of its two ends. The end pieces 254 are fixedly mounted (e.g., fixedly mounted on the base 206), and the sleeve 252 is rotatable relative to the two end pieces 254. Two spring seats 255 are disposed within the sleeve 252, spaced apart along a first direction D1. For example, the two spring seats 255 are adjacent to the two end pieces 254 respectively. A spindle 251 extends through the two spring seats 255 and is fixedly connected to the two end pieces 254. The two spring seats 255 are fixedly connected to the sleeve 252 and are adapted to rotate relative to the spindle 251. A drive spring 253 is connected between each end piece 254 and the adjacent spring seat 255 (in other words, the two ends of each drive spring are connected to the corresponding end piece and spring seat respectively). For example, the drive spring is a torsion spring.

[0061] The curtain assembly 203 includes a curtain 21 (as described above) and a plurality of resilient support rods 22 attached to the curtain 21. These support rods 22 are arranged parallel to each other. In one embodiment, the support rods are made of resilient steel sheets, allowing them to be easily rolled up and unrolled elastically, and possessing appropriate stiffness and strength after unrolling. Such support rods are well known to those skilled in the art, for example, similar to the strips of a steel tape measure, and will not be described further. These support rods are substantially identical to each other; for simplicity, only one support rod will be described below. Of course, depending on the specific circumstances, only one support rod may be provided on the curtain.

[0062] like Figure 4aAs shown, the curtain 21 has two longitudinal edges 214 opposite to each other along a first direction D1, and a first mounting portion 211 and a second mounting portion 212 connected between the two longitudinal edges 214. The first mounting portion 211 and the second mounting portion 212 extend generally along the first direction D1. The first mounting portion 211 is connected to the sleeve 252 of the second roller 202, so that the curtain 21 can be wound onto the second roller 202 and released from the second roller 202 and unfolded along a second direction D2 (the second direction D2 is inclined relative to the vertical direction Z) parallel to the direction of inclination of the front windshield 11. Thus, the curtain 21 is generally parallel to the front windshield 11 after unfolding.

[0063] The support rod 22 includes a mounting end 221, a moving end 222, and a main body section 223 located between the mounting end 221 and the moving end 222. The mounting end 221 is connected to the first roller 201, the moving end 222 is connected to the second mounting portion 212 of the curtain 21, and the main body section 223 is separate from the curtain 21. In one embodiment, refer to... Figure 6a and Figure 6b A take-up holder 207 is provided on the first spool 201. The mounting end 221 of the support rod 22 is connected to the take-up holder 207. Thus, the support rod 22 can be wound onto the first spool 201 and can be released from the first spool 201 and unwound along the second direction D2. In one embodiment, as... Figure 5 As shown, a guide groove 122 extending along the second direction D2 is provided on the instrument panel assembly 121. When the support rod 22 is deployed, the support rod 22 and the curtain 21 extend from the guide groove 122, thereby extending the support rod 22 and the curtain 21 along the second direction D2.

[0064] When the first motor 204 drives the first roller 201 to rotate in the first rotation direction, the support rod 22 is gradually released from the first roller 201 and automatically unfolds in the second direction D2. The support rod 22 also pushes the second mounting part 212 of the curtain 21 away from the second roller 202 in the second direction D2, so that the curtain 21 also extends out from the guide groove 122 on the instrument panel device 121 and gradually unfolds in the second direction D2. During this process, the sleeve 252 and spring seat 255 of the second roller 202 are driven by the curtain 21 to rotate relative to the spindle 251 and rotate synchronously with the first rotating shaft 201. At this time, since the two ends of the drive spring 253 are connected to the end piece 254 and the spring seat 255 respectively, the drive spring 253 is gradually tensioned, and the diameter of the drive spring 253 gradually decreases accordingly (see reference). Figure 4b After the curtain 21 is unfolded, it is generally parallel to the front windshield 11. Thus, at least a portion of the front windshield 11 is obscured by the curtain 21 (e.g., Figure 10 As shown), to prevent direct sunlight from shining into the vehicle's interior. After the curtain 21 is unfolded, the two longitudinal edges 214 are generally parallel to the second direction D2 (as shown). Figure 3 and Figure 4a (As shown). It should be noted that after the curtain assembly 203 is unfolded, the extension direction of the support rod 22 is the same as the unfolding direction of the curtain 21 (both are the second direction D2).

[0065] It should be noted that, such as Figure 3 As shown, the second mounting portion 212 of the curtain 21 has a cutout 210. When the curtain 21 is unfolded, the interior rearview mirror 13 corresponds to the cutout 210 (e.g., ...). Figure 10 As shown), this avoids the rearview mirror 13 being blocked by the curtain 21.

[0066] When the first motor 204 drives the first roller 201 to rotate in a second rotation direction opposite to the first rotation direction, the support rod 22 is wound onto the first roller 201. During this process, the drive spring 253 gradually recovers and drives the sleeve 252 and spring seat 255 of the second roller 202 to rotate relative to the spindle 251, and the sleeve 252 rotates synchronously with the first roller 201. The curtain 21 is gradually wound onto the sleeve 252 of the second roller 202, and the front windshield 11 is exposed (as shown). Figure 11 As shown). During this process, the diameter of the drive spring 253 gradually increases accordingly (refer to...). Figure 4c ).

[0067] Therefore, according to the sunshade device 123 of this application, a first motor 204 is used to drive the first roller 201 to rotate, thereby releasing and retracting the support rod 22, and thus releasing and retracting the curtain 21 from the sleeve 252 of the second roller 202. In this way, the user does not need to manually operate the curtain assembly, improving the user experience of using the sunshade device.

[0068] In one embodiment, the drive spring 253 is also given an appropriate pretension. Thus, during the unfolding of the curtain 21, the drive spring 253 consistently applies appropriate resistance to the rotation of the sleeve 252 of the second roller 202, ensuring that the curtain 21 remains taut and does not slack or wrinkle. The pretension of the drive spring can be determined according to actual conditions and is not limited here.

[0069] It should be understood that when there are multiple support rods, there are also multiple first reels, spaced apart along the first direction D1. Each first reel can carry one or more support rods. There are also multiple first motors, each used to drive the rotation of these first reels.

[0070] In one embodiment, the second roller does not have a drive spring. The sunshade device also includes a second motor (not shown). The second roller is driven by the second motor to rotate synchronously with the first roller. Further details are omitted here. For example, one end of the second roller is formed as a drive end, and the second motor is connected to this drive end. Optionally, both ends of the second roller are formed as drive ends. There are two second motors, each connected to one of the two drive ends, and the two second motors rotate synchronously; further details are omitted here.

[0071] In some existing sunshade devices, multiple support rods are arranged to cross each other. During the movement of the curtain assembly, the curtain may be caught by the support rods, preventing smooth movement. Compared to such existing sunshade devices, in the sunshade device of this application, multiple support rods 22 are arranged parallel to each other along the unfolding direction of the curtain assembly. In this way, the curtain 21 is less likely to be caught by these support rods 22 during movement, allowing the curtain to move smoothly and improving the user's experience with the sunshade device.

[0072] It should be noted that neither the main body section 223 of the support rod 22 nor the mounting end 221 is connected to the curtain fabric 21. Thus, during the movement of the curtain fabric 21, the main body section 223 and the mounting end 221 of the support rod 22 will excessively stretch the layout of the curtain fabric 21, avoiding different deformation amounts in different areas of the curtain fabric 21, and consequently preventing wrinkles from forming in the curtain fabric 21.

[0073] like Figure 5 As shown, the sunshade device 123 also includes a pressing component 24. The pressing component 24 is disposed in front of the first roller 201 along the unfolding direction of the support rod 22. For example, the pressing component 24 is disposed between the moving end 222 of the support rod 22 and the first roller 201 and is adjacent to the first roller 201. When the support rod 22 unfolds, the pressing component 24 presses the support rod 22, making the support rod 22 flat to stably support the curtain fabric 21. When the support rod 22 retracts, the pressing component 24 also presses the support rod 22, making the support rod 22 flat to smoothly retract onto the first roller 201.

[0074] like Figure 6a and Figure 6b As shown, the pressing assembly 24 includes a support shaft 241 and a plurality of pressure rollers 242 mounted on the support shaft 241. The support shaft 241 is arranged side by side with the first reel 201 (e.g., the support shaft 241 is generally parallel to the first reel 201). These pressure rollers 242 also correspond to a plurality of support rods 22. These pressure rollers are identical to each other; for simplicity, only one pressure roller will be described below.

[0075] The pressing assembly 24 also includes a transmission assembly 243 (e.g., a gear set). The first motor 204 drives the bearing shaft 241 to rotate in the same direction as the first reel 201 via the transmission assembly 243, and the rotation direction of the pressure roller 242 is also the same as the rotation direction of the first reel 201. In this way, after the support rod 22 is released from the first reel 201, the pressure roller 242 presses down on the corresponding support rod 22, making the support rod 22 flat.

[0076] In one embodiment, the pressure roller 242 rotates at a higher speed than the first reel 201. Thus, during the movement of the support rod 22, the pressure roller 242 pushes the corresponding support rod 22, facilitating its smooth unfolding and rewinding. The speed of the pressure roller can be adjusted via a transmission assembly, which will not be elaborated here. In one embodiment, the pressure roller rotates at approximately 40 rpm, and the first reel rotates at approximately 38 rpm.

[0077] For example Figure 5 As shown, the support 208 is also provided with a support block 124 corresponding to the pressure roller 242. The support rod 22 passes through the guide gap 125 between the support block 124 and the pressure roller 242, and is pressed towards the support block 124 by the pressure roller 242. Under the combined action of the pressure roller 242 and the guide block 124, the support rod 22 can be pressed flatter. In one embodiment, the guide gap 125 is aligned with the guide groove 122 on the instrument panel device 121 along the second direction D2. In this way, the guide gap 125 also guides the support rod 22 along the second direction D2, so that the support rod 22 is substantially parallel to the second direction D2 after unfolding.

[0078] like Figure 3 and Figure 4a As shown, a pull rod 215 extending along the first direction D1 is provided at the second mounting portion 212 of the curtain 21. The pull rod 215 stretches the curtain 21 along the first direction D1 to prevent the curtain 21 from slack and / or wrinkle.

[0079] The pull rod 215 has multiple protrusions 218. During the unfolding of the curtain 21, the curtain 21 is supported by the support rod 22 and tilted along the second direction D2, and the protrusions 218 on the pull rod 215 abut against the front windshield 11. In this way, the curtain 21 is constrained by the support rod 22 and the protrusions 218 and cannot sway towards or away from the front windshield 11, which helps to improve the quality of the sunshade device. In addition, the small contact area between the protrusions 218 and the front windshield 11 helps to reduce the movement resistance of the curtain 21 and helps to prevent the front windshield 11 from being worn. It should be understood that the protrusions can contact the front windshield when the curtain is unfolded, or they can contact the front windshield after the curtain has moved a predetermined distance during unfolding; this will not be elaborated here.

[0080] The moving end 222 of the support rod 22 is connected to the pull rod 215 (that is, the moving end 222 of the support rod 22 is connected to the second mounting part 212 of the curtain 21). In one embodiment, such as Figure 7 As shown, a connecting hook 224 is provided at the moving end 222 of the support rod 22, and the connecting hook 224 is connected to the pull rod 215. In one embodiment, the connecting hook and the support rod can be integrally formed. Of course, the connecting hook and the support rod can also be formed independently and then assembled together.

[0081] like Figure 3 As shown, the curtain fabric 21 is provided with two side strips 216, which extend parallel to each other along the second direction D2 and are spaced apart along the first direction D1. For example, the two side strips 216 are adjacent to the two longitudinal edges 214 of the curtain fabric 21, respectively. In one embodiment, the side strips are implemented as elastic plastic strips with appropriate stiffness and strength. The two side strips 216 also provide appropriate support for the curtain fabric 21 along the second direction D2, helping to prevent the curtain fabric 21 from slack or wrinkling. It should be understood that the side strips 216 are rolled onto or released from the second roller 202 as the curtain fabric 21 is rolled up (e.g., ...). Figure 12 (As shown).

[0082] For example Figure 3 As shown, the sunshade device 123 also includes two tensioning components 23 corresponding to the two side strips 216. The two tensioning components 23 are spaced apart along a first direction D1, and the two side strips 216 are located between the two tensioning components 23. Each side strip 216 is slidably engaged with the corresponding tensioning component 23, and the two side strips 216 are constrained by the two tensioning components 23 along the first direction D1 to be far apart from each other. In this way, the curtain fabric 21 is tensioned along the first direction D1 by the two tensioning components 23, preventing the curtain fabric 21 from becoming loose or wrinkled.

[0083] The two edge strips are basically the same, and the two tensioning components are also basically the same. For simplicity, only one edge strip and its corresponding tensioning component will be described below. Figure 8a As shown, the side strip 216 is connected to the curtain fabric 21 along its width at its center. For example, the side strip 216 is sewn onto the curtain fabric 21. Figure 8a The sewing mark 219 is shown. The side strip 216 also has a free portion 217 separate from the curtain 21. The free portion 217 extends along the longitudinal direction of the side strip 216 (i.e., the second direction D2). The free portions 217 of the two side strips 216 face each other along the first direction D1. In other words, the free portion 217 is located on the side of the sewing mark 219 opposite to the corresponding tensioning assembly 23.

[0084] For example Figure 8a and Figure 8bAs shown, the tensioning assembly 23 includes a mounting plate 231 and a tensioning frame 232 disposed on the mounting plate 231. In one embodiment, the tensioning frame 232 is disposed on the mounting plate 231 via a connecting seat 235. The mounting plate 231 is disposed along a first direction D1 on a side opposite to the free portion 217 of the edge strip 216. The tensioning frame 232 extends along the first direction D1 from the mounting plate 231 toward the free portion 217 of the edge strip 216 and is slidably engaged with the free portion 217.

[0085] Also refer to Figure 8a , Figure 8b and Figure 9 The tensioning frame 232 includes a tensioning plate 234 and pressing plates 233. The tensioning plate 234 is slidably positioned between the free portion 217 and the curtain fabric 21. Thus, the two tensioning plates 234 apply opposing tensions to the two side strips 216, thereby tensioning the curtain fabric 21 along a first direction D1 and preventing it from becoming loose or wrinkled. There are two pressing plates 233, positioned on either side of the tensioning plate 234 along a second direction D2. As the curtain fabric 21 and side strips 216 move, the two pressing plates 233 press the side strips 216 towards the curtain fabric 21, which helps prevent the tensioning plate 234 from disengaging from the free portion 217 of the side strips 216.

[0086] In addition, the mounting plate 231 is generally parallel to the curtain 21 and slidably contacts the curtain 21. During the movement of the curtain 21, the mounting plate 231 exerts appropriate pressure on the curtain 21, which also helps to prevent the curtain 21 from loosening or wrinkling.

[0087] A second embodiment of the sunshade device.

[0088] The second embodiment of the sunshade device is similar to the first embodiment of the sunshade device; for simplicity, only the differences between the two will be described below.

[0089] like Figure 13 As shown, in the second embodiment of the sunshade device, a first roller 201 is provided. The mounting end 221 of the support rod 22 and the first mounting portion 211 of the curtain fabric 21 are both connected to the first roller 201. Furthermore... Figure 15 As shown, the first roller 201 is driven to rotate by the third motor 209 so that the support rod 22 and the curtain 21 can be wound onto the first roller 201 and released from the first roller 201 and unfolded in the second direction D2.

[0090] Also refer to Figure 13 and Figure 14The curtain fabric 21 is also provided with multiple mounting sleeves 213 that extend generally parallel to each other along the second direction D2. Each support rod 22 is installed in the corresponding mounting sleeve 213. It should be noted that the main body section 223 of the support rod 22 is movable relative to the mounting sleeve 213. In other words, the main body section 223 of the support rod 22 is not fixedly connected to the mounting sleeve 213. In this way, during the movement of the curtain fabric 21, the main body section 223 of the support rod 22 will not excessively stretch any part of the curtain fabric 21, avoiding different deformation amounts in different areas of the curtain fabric 21, and thus preventing wrinkles from forming in the curtain fabric 21.
