[0052] 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.
[0053] Figure 1 A vehicle 1 according to one embodiment of this application is schematically shown. Figure 1As shown, the vehicle 1 comprises a vehicle roof 12. A sunroof opening 11 is provided on the vehicle roof 12, and a sunroof device (hereinafter referred to as the sunroof device 2) for the vehicle is installed at the sunroof opening 11.
[0054] The sunroof device will be described below.
[0055] Referring to Figure 2 and Figure 3 , the sunroof device 2 comprises a sunroof glass assembly 21 and a sunshade curtain assembly 22 installed on the sunroof glass assembly 21.
[0056] The sunroof glass assembly 21 comprises two glass plates (i.e., an inner glass plate 211a facing the vehicle cabin and an outer glass plate 211b away from the vehicle cabin) stacked along a height direction Z of the vehicle. The inner glass plate 211a and the outer glass plate 211b are spaced apart from each other along the height direction Z, thereby forming an accommodation space 212 therebetween. In some vehicles, the sunroof glass assembly can also be formed as a vehicle roof (i.e., the vehicle roof is a glass canopy). Such a sunroof glass assembly has good heat and sound insulation, which helps to improve the ride experience of the occupants.
[0057] Referring to Figure 2 and Figure 4 , the sunshade curtain assembly 22 mainly comprises a curtain cloth 23, a roller assembly 24 and a first driving member 25. In addition, the sunshade curtain assembly 22 further comprises two guide rails (i.e., a first guide rail 26a and a second guide rail 26b).
[0058] The curtain cloth 23 is generally rectangular and has two longitudinal edges (i.e., a first longitudinal edge 231a and a second longitudinal edge 231b) extending along a first direction D1 and a first transverse edge 232 and a second transverse edge (not shown in the figure) extending along a second direction D2 substantially perpendicular to the first direction D1. The first transverse edge 232 and the second transverse edge are opposite along the first direction D1.
[0059] The first guide rail 26a and the second guide rail 26b both extend along the first direction D1 and are located on both sides of the curtain cloth 23 along the second direction D2 (for example, the first guide rail 26a is arranged adjacent to the first longitudinal edge 231a, and the second guide rail 26b is arranged adjacent to the second longitudinal edge 231b). In this way, the curtain cloth 23 can reciprocate within the accommodation space 212 along the first direction D1 under the guidance of the two guide rails. The first guide rail 26a and the second guide rail 26b are completely identical, and for the sake of simplicity, the technical solution of the present application will be described below only by way of example of the first guide rail and the components cooperating with the first guide rail (such as the slide foot described below).
[0060] The roller assembly 24 is mounted on the sunroof glass assembly 21 and is located at one side of the curtain 23 along the first direction Dl. The second lateral edge of the curtain 23 is connected to the roller assembly 24 so that the curtain 23 can be reeled onto or released from the roller assembly 24. In one embodiment, the length of the outer glass panel 211b along the first direction Dl is greater than that of the inner glass panel 211a, so that the roller assembly 24 can be mounted on the inner surface of the outer glass panel 211b without being in the receiving space 212. Of course, the roller assembly can also be arranged in the receiving space according to actual conditions.
[0061] The first driving member 25 is also mounted on the sunroof glass assembly 21 and is located opposite the roller assembly 24 along the first direction Dl. From the perspective of the sunroof device 2 as a whole, the first driving member 25 and the roller assembly 24 are generally located at two sides of the curtain 23 along the first direction Dl. In one embodiment, the first driving member 25 is mounted on the inner surface of the outer glass panel 211b without being in the receiving space 212. Of course, the first driving member can also be arranged in the receiving space according to actual conditions. The first lateral edge 232 of the curtain 23 can be driven by the first driving member 25 to be pulled along the first direction Dl.
[0062] When it is required to shield the sunroof glass assembly 21, the roller assembly 24 is positively rotated to release the curtain 23, while the first driving member 25 pulls the first lateral edge 232 of the curtain 23 to move away from the roller assembly 24 in the receiving space 212 along the first direction Dl. In this way, the curtain 23 gradually unfolds in the receiving space 212 along the first direction Dl and shields the sunroof glass assembly 21. When it is required to expose the sunroof glass assembly 21, the roller assembly 24 is reversely rotated to reel the curtain 23, and the first lateral edge 232 of the curtain 23 moves toward the roller assembly 24 along the first direction Dl (at this time, the first driving member 25 only serves to tension the curtain 23, but does not prevent the curtain 23 from moving). In this way, the curtain 23 is gradually reeled onto the roller assembly 24, so that the sunroof glass assembly 21 is exposed. It should be understood that, according to requirements, the curtain can also stop to shield only a part of the sunroof glass assembly (as shown in FIG. 2B). Figure 2 It should also be understood that the relationship between the moving direction of the curtain 23 and the rotating direction of the roller assembly (i.e., the forward and reverse directions) can be specified according to actual conditions, which is not limited here.
[0063] After the curtain 23 is unfolded in the receiving space 212, the inner glass panel 211a supports the curtain 23. In this way, the curtain 23 will not sag into the vehicle cabin, avoiding the height of the vehicle cabin from being lowered to bring an adverse riding experience to the occupant.
[0064] For the prior art sunshade assembly with the sunshade installed in the vehicle cabin, in order to reduce the natural sag of the sunshade cloth, a side strip is usually arranged at the longitudinal edge of the sunshade cloth, and the side strip is slidably engaged with the guide rail of the sunshade assembly to tension the sunshade cloth. In comparison with the prior art, in the present application, the sunshade cloth 23 is supported by the inner glass panel 211a, and thus the side strip as in the prior art does not need to be arranged at the two longitudinal edges of the sunshade cloth 23. This helps to reduce the diameter of the roll formed by the sunshade cloth 23 when it is wound onto the winding shaft assembly 24, and thus the sunshade assembly 22 is miniaturized. Moreover, each longitudinal edge of the sunshade cloth 23 can be spaced apart from the corresponding guide rail, which helps to reduce the movement resistance and noise of the sunshade cloth 23. The structure for slidably engaging the side strip with the guide rail also does not need to be arranged on the guide rail, which helps to simplify the structure of the guide rail and the manufacturing of the guide rail, and the guide rail is miniaturized to facilitate the use in a narrow space (for example, the first guide rail 26a and the second guide rail 26b are installed in the accommodation space 212, as shown in Figure 3
[0065] In addition, the accommodation space 212 also prevents the noise generated when the sunshade cloth 23 moves from spreading into the vehicle cabin, thereby further improving the ride experience of the occupant.
[0066] When the sunshade cloth 23 moves in the accommodation space 212, it is protected by the inner glass panel 211a and the outer glass panel 211b, so that the sunshade cloth 23 is basically not disturbed and hindered by the outside, which ensures smooth movement of the sunshade cloth 23. Moreover, the inner glass panel 211a spaces the sunshade cloth 23 away from the vehicle cabin, so that the occupant cannot touch the sunshade cloth 23, which helps to improve the service life of the sunshade cloth 23 and the sunshade assembly 22.
[0067] In one embodiment, the size of the accommodation space 212 in the height direction Z is 20mm to 25mm. The size of the first guide rail 26a in the height direction Z is 15mm to 17mm. In this way, the first guide rail 26a can also be arranged in the accommodation space 212 (the same applies to the second guide rail 26b). The first guide rail 26a and the second guide rail 26b are shielded and protected by the sunroof glass assembly 21, which helps to avoid damage to the first guide rail 26a and the second guide rail 26b, and also helps to improve the headroom of the occupant. Of course, according to actual conditions, the first guide rail and / or the second guide rail can also be arranged outside the accommodation space. In addition, the size of the accommodation space in the height direction Z can also be set to other values, and the same applies to the first guide rail and the second guide rail, which are not limited here.
[0068] Referring to Figure 4 and Figure 5 The first driving member 25 includes a winding device 251 and a pulling rope 252. The winding device 251 is opposite to the winding shaft assembly 24 along the first direction Dl. The pulling rope 252 extends from the winding device 251 and is connected to the two ends of the first lateral edge 232 of the curtain 23. When the curtain 23 needs to be unfolded, the winding shaft assembly 24 rotates forward to release the curtain 23, while the pulling rope 252 is wound onto the winding device 251 and pulls the first lateral edge 232 of the curtain 23 away from the winding shaft assembly 24 along the first direction Dl, so that the curtain 23 is gradually unfolded. When the winding shaft assembly 24 rotates reversely and winds up the curtain 23, the pulling rope 252 is released from the winding device 251 and is used to tension the curtain 23.
[0069] The pulling rope can be a steel wire rope. Of course, according to actual conditions, any other suitable material can be used to manufacture the pulling rope, which is not limited here.
[0070] The winding device 251 includes a rotating shaft 253 and a spiral spring 254. The pulling rope 252 and the spiral spring 254 are adapted to be wound onto or released from the rotating shaft 253. Specifically, when the curtain 23 is wound on the winding shaft assembly 24, the sunroof glass assembly 21 is in an initial state. In this initial state, the spiral spring 254 is wound on the rotating shaft 253, and the pulling rope 252 is released from the rotating shaft 253. When the curtain 23 is gradually unfolded, the curtain 23 is released from the winding shaft assembly 24. At the same time, the spiral spring 254 is gradually released from the rotating shaft 253 (i.e., the spiral spring 254 gradually relaxes and releases elastic potential energy) and drives the rotating shaft 253 to rotate forward, and the pulling rope 252 is gradually wound onto the rotating shaft 253. In this way, the pulling rope 23 pulls the first lateral edge 232 of the curtain 23 away from the winding shaft assembly 24, so that the curtain 24 is gradually unfolded and kept tensioned. When the curtain 23 is unfolded to the maximum, the winding shaft assembly 24 stops rotating, and the spiral spring 254 also stops driving the rotating shaft 253 to rotate. When the curtain 23 is wound up by the winding shaft assembly 24, the pulling rope 252 is released from the rotating shaft 253 and drives the rotating shaft 253 to rotate reversely, so that the spiral spring 254 is wound onto the rotating shaft 253 (i.e., the spiral spring 254 gradually tightens and accumulates elastic potential energy). It should be understood that the rotating direction of the rotating shaft (i.e., forward and reverse) can be specified according to actual conditions, which is not limited here.
[0071] When the spiral spring 254 gradually relaxes, it releases the elastic potential energy at a substantially uniform speed and provides a substantially constant pulling force to the pulling rope 252. The pulling rope 252 and the curtain 23 can thus move at a substantially uniform speed until the curtain 23 is completely unfolded. The spiral spring is well known to those skilled in the art, which will not be described here.
[0072] As Figure 4As shown, the number of the volute springs 254 is two to provide sufficient power for the cord 252 to pull the shade 23 to move. Of course, only one volute spring can be provided according to actual conditions, which is not limited herein.
[0073] In one embodiment, the reel includes two spaced-apart sections (not shown in the figures). The cord is wound in one section, and the volute spring is wound in the other section. This avoids the interference between the cord and the volute spring wound on the shaft to cause the shade to be unable to be smoothly unfolded or wound.
[0074] It should also be noted that at least part of the volute spring is still wound on the shaft when the shade is fully unfolded. In other words, the volute spring 254 is installed on the shaft 253 in a pre-tensioned state. In this way, the volute spring 254 always exerts a driving force on the shaft 253 to keep the cord 252 in a tensioned state, and in turn, the shade 23 is always in a tensioned state.
[0075] Also as Figure 5 As shown, the cord 252 includes two pulling sections (i.e., a first pulling section 252a and a second pulling section 252b) extending along the first direction D1 and a connecting section 252c (e.g., the connecting section 252 generally extends along the second direction D2) connected between the first pulling section 252a and the second pulling section 252b.
[0076] The connecting section 252c extends across the first lateral edge 232 of the shade 23 along the second direction D2 (i.e., the length direction of the first lateral edge 232 of the shade 23). The first pulling section 252a and the second pulling section 252b are on both sides of the shade 23 along the second direction D2 and extend along the first guide rail 26a (or the first longitudinal edge 231a) and the second guide rail 26b (or the first longitudinal edge 231b), respectively. The first pulling section 252a and the second pulling section 252b are used to pull the respective ends of the first lateral edge 232 of the shade 23, respectively. The first pulling section 252a and the second pulling section 252b are wound onto or released from the cord winder 251 (or the shaft 253), respectively. In other words, the shade 23 is pulled by one cord. The pulling force exerted by the cord on both ends of the first lateral edge 232 of the shade 23 is equal, which helps to avoid the shade 23 from being skewed when being unfolded or wound.
[0077] According to actual conditions, two cords can also be used to pull the two ends of the first lateral edge of the shade, respectively, which is not described in detail herein.
[0078] It should also be understood that the lengths of the first and second pulling sections are changing during the unwinding or winding of the curtain, but the length of the connecting section is substantially constant. For example, during unwinding of the curtain, the first and second pulling sections are gradually wound onto the rope winder, and the lengths of the first and second pulling sections gradually decrease. During winding of the curtain, the first and second pulling sections are gradually released from the rope winder, and the lengths of the first and second pulling sections gradually increase. The length of the connecting section is always substantially equal to the length of the first lateral edge of the curtain.
[0079] As shown in Figure 6 , the first guide rail 26a is provided with a slide 264 extending in the first direction D1, and the first pulling section 252a moves in the slide 264, so that the first pulling section 252a is not disturbed during movement, and the curtain 23 can move smoothly. The same applies to the second guide rail 26b and the second pulling section 252b.
[0080] Referring to Figure 4 and Figure 7 , both ends of the first lateral edge 232 of the curtain 23 are provided with slides (for example, a first slide 27a towards the first guide rail 26a and a second slide 27b towards the second guide rail 26b). As shown in Figure 7 , taking the first slide 27a as an example, the first slide 27a has a sliding part 274 which is in sliding cooperation with the slide 264 in the first guide rail 26a. The pull rope 252 (or two pulling sections of the pull rope 252) is connected to the first slide 27a and the second slide 27b. In this way, when the curtain 23 is unwound, the pull rope 252 pulls the first slide 27a and the second slide 27b to move, and the curtain 23 also moves. In addition, the sliding part 274 of the first slide 27a shares a slide 264 with the first pulling section 252a, which helps to simplify the structure of the first guide rail 26a and miniaturize the first guide rail 26a. The same applies to the second guide rail 26b and the second slide 27b.
[0081] In one embodiment, a pulley (not shown in the figure) is installed on each slide. The pull rope extends around the pulley. When the pull rope moves relative to the slide, the pulley rotates, which reduces the movement resistance of the pull rope and helps to reduce noise.
[0082] As also shown in Figure 6 , the slide 264 includes a first receiving groove 261 and a second receiving groove 262 opposite in the height direction Z (for example, the first receiving groove 261 extends upward in the height direction Z, and the second receiving groove 262 extends downward in the height direction Z), and a third receiving groove 263 extending away from the curtain 23 in the second direction D1. As shown in Figure 7As shown, the sliding portion 274 includes a first protruding portion 271 matching the first receiving groove 261, a second protruding portion 272 matching the second receiving groove 262, and a third protruding portion 273 matching the third receiving groove 263. In this way, the sliding portion 274 can be slidably engaged with the slide 264. During the movement of the curtain fabric 23, the receiving grooves of the slide 264 and the protruding portions of the sliding portion 274 can prevent the sliding portion 274 from being deflected within the slide 264, thereby avoiding the deflection of the curtain fabric 23.
[0083] In other embodiments, the slide can also include only any one or two of the first receiving groove, the second receiving groove, and the third receiving groove; correspondingly, the sliding portion can also include only any one or two of the first protruding portion, the second protruding portion, and the third protruding portion.
[0084] Further as Figure 4 As shown, the first lateral edge 232 of the curtain fabric 23 is provided with a pull rod 28 extending along the second direction D2. The pull rod 28 props open the curtain fabric 23, which also helps to avoid the occurrence of wrinkles in the curtain fabric 23.
[0085] The pull rod 28 is also within the accommodation space 212. In this way, the pull rod 28 cannot be contacted by the occupant, thereby avoiding the injury of the occupant by the pull rod 28 and avoiding the damage of the sunshade curtain assembly 22 caused by the accidental pulling of the pull rod 28 by the occupant.
[0086] As Figure 2 shown, the first driving member 25 (e.g., the winding rope device 251) is carried by a first bracket 255, which is mounted on the inner surface of the outer glass plate 211b through a plurality of first connecting modules (not shown in the figure) separated from each other. The winding shaft assembly 24 is carried by a second bracket 243, which is mounted on the inner surface of the outer glass plate 211b through a plurality of second connecting modules (not shown in the figure) separated from each other. For example, the first connecting modules and the second connecting modules are polyurethane modules.
[0087] Thus, instead of providing a long polyurethane strip on the sunroof glass assembly to mount the first driving member and the winding shaft assembly as in the prior art, only a few polyurethane modules need to be provided at a few preset positions on the sunroof glass assembly. This reduces the amount of polyurethane used, thereby reducing the cost of the sunroof device. It should be understood that the first connecting modules and the second connecting modules can also be made of other materials, which are not limited here.
[0088] Referring to Figure 4 and Figure 5The reel assembly 24 includes a reel body 241 and a second driving member 242. The second driving member 242 is connected to one end of the reel body 241 to directly drive the reel body 241 to rotate and wind or release the curtain fabric 23. This connection of the reel body 241 and the second driving member 242 helps to improve the working reliability of the sunshade curtain assembly 22. In one embodiment, the second driving member 242 is a motor.
[0089] The above description is merely illustrative of the embodiments of the present application and is not intended to limit the present application. Since various modifications and changes can be made to the present application by those skilled in the art, it is intended that the present application encompass such modifications and changes as fall within the scope of the appended claims.
