Description

Technical Field

[0001] This invention relates to the field of automotive technology, and in particular to a sunshade device, glass assembly, and vehicle. Background Technology

[0002] With the increasing popularity of automobiles, people are paying more and more attention to car maintenance. Prolonged exposure to direct sunlight accelerates the aging of internal components and raises the interior temperature, causing harmful substances in certain materials to evaporate and endanger human health. Sunshades are auxiliary products used for car sun protection. By blocking the car windows from the inside, they reduce the amount of direct sunlight entering the car, thus mitigating the harmful effects of sun exposure. Related sunshade devices include the sunshade itself, a linkage mechanism, and a drive mechanism. The sunshade consists of two panels, left and right, positioned inside the windshield, extending from the top to the bottom to block the windshield. The two panels are also located on either side of the rearview mirror area. The drive mechanism drives the linkage mechanism to move the top parts of the two sunshades up and down to close or open the sunshade. However, in related sunshade devices, because the sunshade needs to avoid the rearview mirror area, light leakage occurs, and it cannot completely block the windshield. Summary of the Invention

[0081] The sunshade device of this application is described below with reference to the accompanying drawings. The sunshade device of this application is applied to the glass components of a vehicle, such as the windshield.

[0082] exist Figure 1 In the example, for ease of observation, Figure 1 The accompanying diagram at the top of the middle view shows the driving component 70 omitted for illustrative purposes. Figure 1 The attached diagram at the bottom of the middle view shows the first curtain 10, the second curtain 20, and the third curtain 30 omitted for illustration.

[0083] Reference Figure 1 The sunshade device 100 provided in this application embodiment includes an upper section curtain 101, a lower section curtain 102, and a drive assembly 70. The drive assembly 70 is configured to drive the upper section curtain 101 and the lower section curtain 102 to unfold or retract. The upper section curtain 101 is disposed at least on the side of the rearview mirror area 410, and the lower section curtain 102 is disposed on the bottom side of the rearview mirror area 410. When the upper section curtain 101 and the lower section curtain 102 are unfolded, they are joined together as a whole to surround the rearview mirror area 410. In this application embodiment, in use, the upper section curtain 101 can be disposed above the lower section curtain 102.

[0084] By setting up an upper partition curtain 101, a lower partition curtain 102, and a drive component 70, the drive component 70 is configured to drive the upper partition curtain 101 and the lower partition curtain 102 to unfold or retract. As long as the drive component 70 is used to drive, the upper partition curtain 101 and the lower partition curtain 102 can be unfolded or retracted, realizing the switching between the sunshade state and the non-sunshade state of the sunshade device 100. The operation is relatively simple and convenient. In addition, the upper partition curtain 101 is used to be disposed at least on the side of the rearview mirror area 410, and the lower partition curtain 102 is used to be disposed on the bottom side of the rearview mirror area 410. When the upper partition curtain 101 and the lower partition curtain 102 are unfolded, they are spliced ​​together as a whole to surround the rearview mirror area 410. When the upper partition curtain 101 and the lower partition curtain 102 are unfolded, they can cover the area around the rearview mirror area 410 from at least the bottom side and the side side of the rearview mirror area 410. Therefore, there will be no light leakage area around the rearview mirror area 410, which can improve the light blocking effect of the sunshade device 100.

[0085] In this embodiment, the lower partition curtain 102 includes a first curtain 10, and the upper partition curtain 101 includes a second curtain 20 and a third curtain 30. The second curtain 20 and the third curtain 30 are respectively disposed on opposite sides of the rearview mirror area 410 along a first direction F. When the first curtain 10, the second curtain 20, and the third curtain 30 are unfolded, they are joined together to form a whole to surround the rearview mirror area 410, wherein the first direction F is the vehicle width direction. Here, the first curtain 10 is located on the bottom side of the rearview mirror area 410, and therefore can be located below the second curtain 20 and the third curtain 30. In this way, the second curtain 20 and the third curtain 30 are located on the left and right sides of the rearview mirror area 410, respectively, and the first curtain 10 is located on the lower side of the rearview mirror area 410. It can surround the rearview mirror area 410 on the left, right and lower sides, avoid the existence of light leakage areas around the rearview mirror area 410, and improve the light blocking effect of the sunshade device 100.

[0086] In this embodiment of the application, the sunshade device 100 further includes a plurality of drive sliders 50 and guide rails 60 that slide and cooperate with each other.

[0087] The first curtain 10, the second curtain 20, and the third curtain 30 are each provided with at least one driving slider 50 and a guide rail 60, and the first curtain 10, the second curtain 20, and the third curtain 30 are all connected to the corresponding driving slider 50.

[0088] Furthermore, the drive assembly 70 is connected to the drive slider 50 corresponding to the first curtain 10, the second curtain 20, and the third curtain 30. The drive assembly 70 is used to drive the drive slider 50 to move along the corresponding guide rail 60 so that the first curtain 10, the second curtain 20, and the third curtain 30 can be unfolded or retracted.

[0089] Each of the first curtain 10, the second curtain 20, and the third curtain 30 is equipped with at least one set of drive sliders 50 and guide rails 60, and each is connected to the corresponding drive slider 50. Therefore, when the drive slider 50 moves along the guide rail 60, it can drive the curtain connected to the drive slider 50 to move along the extension direction of the guide rail 60.

[0090] The drive assembly 70 is connected to the corresponding drive sliders of the first curtain 10, the second curtain 20, and the third curtain 30, and is used to drive the corresponding drive sliders 50 of the first curtain 10, the second curtain 20, and the third curtain 30 to move along the corresponding guide rails 60, so that the first curtain 10, the second curtain 20, and the third curtain 30 can be unfolded or retracted. Therefore, as long as the drive assembly 70 drives the drive sliders 50 to move along the corresponding guide rails 60, the unfolding or retraction of the first curtain 10, the second curtain 20, and the third curtain 30 can be achieved.

[0091] In this embodiment, the first curtain 10, the second curtain 20, and the third curtain 30 can be elastic fabrics or other flexible materials, such as high-precision blackout fabrics coated with reflective materials such as silver fabrics.

[0092] When deployed, the first curtain 10, the second curtain 20, and the third curtain 30 should completely cover the windshield 40. The outer contours of the first curtain 10, the second curtain 20, and the third curtain 30 should perfectly match and conform to the outer contour of the rearview mirror area 410, and also be roughly the same as the outer contour of the windshield 40. Furthermore, the edge of the overall outer contour of the first curtain 10, the second curtain 20, and the third curtain 30 should be located outside the outer edge of the windshield 40.

[0093] The first curtain 10, the second curtain 20, and the third curtain 30 are each equipped with at least one driving slider 50 and a guide rail 60. In this embodiment, the first curtain 10 is connected to two driving sliders 50 and guide rails 60. The second curtain 20 is connected to two driving sliders 50 and guide rails 60. The third curtain 30 is connected to two driving sliders 50 and guide rails 60, and is also connected to two driving sliders 50, as an example.

[0094] For example, when the first curtain 10 corresponds to two drive sliders 50 and guide rails 60, the drive sliders 50 and guide rails 60 corresponding to the first curtain 10 are defined as the first drive slider 51 and the first guide rail 61.

[0095] Two first guide rails 61 are arranged opposite each other along the first direction F. The two first guide rails 61 are used to connect to the two A-pillars of the vehicle. Two first drive sliders 51 are respectively connected to the opposite sides of the first curtain 10 along the first direction F.

[0096] In this way, when the two first drive sliders 51 are driven respectively, they can drive the first curtain 10 to move along the extension direction of the first guide rail 61 on both sides of the first direction F.

[0097] The extension direction of each first guide rail 61 can be determined according to the extension direction of the A-pillar to which it is connected. For example, when the two A-pillars are inclined and located on the two sides of a trapezoid, the two first guide rails 61 are also located on the two sides of the trapezoid. The bottom end of the first curtain 10 can be fixedly connected to the junction of the windshield 40 and the center console of the vehicle. The two first drive sliders 51 can be located at the top end of the first curtain 10 respectively. This facilitates the movement of the top end of the first curtain 10 when the first drive slider 51 slides, so that the first curtain 10 can be opened or closed.

[0098] In this embodiment, reference continues to be made to... Figure 1 The second curtain 20 and the third curtain 30 are respectively set on opposite sides of the rearview mirror area 410 along the first direction F, and the second curtain 20 and the third curtain 30 are each corresponding to two drive sliders 50 and guide rails 60.

[0099] The driving slider 50 and guide rail 60 corresponding to the second curtain 20 are defined as the second driving slider 52 and the second guide rail 62, and the driving slider 50 and guide rail 60 corresponding to the third curtain 30 are defined as the third driving slider 53 and the third guide rail 63.

[0100] In the embodiments of this application, it can be as follows: Figure 1 As shown, two second guide rails 62 are respectively connected to one of the A-pillars and the first side edge 411 of the rearview mirror area 410 along the first direction F, and two third guide rails 63 are respectively connected to the other A-pillar and the second side edge 421 of the rearview mirror area 410 along the first direction F.

[0101] Alternatively, in some other embodiments, it can also be as follows: Figure 2 As shown, the two ends of each second guide rail 62 are respectively connected to one of the A-pillars and the first side edge 411 of the rearview mirror area 410 along the first direction F, and the two ends of each third guide rail 63 are respectively connected to the other A-pillar and the second side edge 412 of the rearview mirror area 410 along the first direction F.

[0102] In the embodiments of this application, Figure 1In the illustration above, the second and third blind curtains 20 and 30 are positioned at least as high as the bottom of the rearview mirror area 410 along the windshield 40, while the first blind curtain 10 is positioned at least as high as the bottom of the rearview mirror area 410 along the windshield 40. In fact, when the first blind curtain 10, second blind curtain 20, and third blind curtain 30 are deployed, the junction between the bottom ends of the second and third blind curtains 20 and the top end of the first blind curtain 10 is collinear with the bottom edge of the rearview mirror area 410. Thus, when deployed, the entire first blind curtain 10, second blind curtain 20, and third blind curtain 30 can completely cover the perimeter of the rearview mirror area 410.

[0103] exist Figure 1 In the illustrated embodiment, of the two second guide rails 62, one second guide rail 62 extends along the extension direction of one of the A-pillars (e.g., the A-pillar on the left side of the figure) and is integrally connected to that A-pillar; the other second guide rail 62 extends along the first side edge 411 of the rearview mirror area 410 and is integrally connected to the first side edge 411. Thus, when the two second drive sliders 52 slide in engagement with the two second guide rails 62, the second curtain 20 unfolds or retracts approximately along the height direction of the windshield 40. Furthermore, it can be well adapted to different vehicle models when the position of the rearview mirror area 410 varies.

[0104] In this embodiment, since the first curtain 10, the second curtain 20, and the third curtain 30 are set in separate sections and controlled independently, and since the first curtain 10, the second curtain 20, and the third curtain 30 all move in the vertical direction, it can avoid interfering with driving operations. In addition, the second curtain 20 and the third curtain 30 are positioned at the top of the windshield 40, which can function as sun visors.

[0105] Of the two third guide rails 63, one third guide rail 63 extends along the extension direction of another A-pillar (e.g., the A-pillar on the right side of the figure) and is integrally connected to that A-pillar, while the other third guide rail 63 extends along the second side edge 421 of the rearview mirror area 410. Thus, when the two third drive sliders 53 slide in engagement with the two third guide rails 63, the third blind curtain 30 expands or retracts approximately along the height direction of the windshield 40.

[0106] In this embodiment, the first guide rail 61 and the second guide rail 62 connected to one of the A-pillars are constructed as a single unit, and the first guide rail 61 and the third guide rail 63 connected to the other A-pillar are also constructed as a single unit. This facilitates manufacturing and installation. In other embodiments, the first guide rail 61 and the second guide rail 62 connected to one of the A-pillars can also be constructed as separate units, and the first guide rail 61 and the third guide rail 63 connected to the other A-pillar can also be constructed as separate units.

[0107] In the embodiments of this application, Figure 2 In the example shown, two second guide rails 62 are arranged at intervals along the extension direction of the A-pillar. One end of each second guide rail 62 is connected to one of the A-pillars (e.g., the A-pillar on the left side of the figure), and the other end is connected to the first side edge 411 of the rearview mirror area 410. The two second guide rails 62 extend along the first direction F. Thus, when the two second drive sliders 52 slide in engagement with the two second guide rails 62, the second curtain 20 unfolds or retracts approximately along the first direction F.

[0108] Two third guide rails 63 are arranged at intervals along the extension direction of the A-pillar. One end of each third guide rail 63 is connected to the other A-pillar (e.g., the A-pillar on the right side of the figure), and the other end is connected to the second side edge 421 of the rearview mirror area 410. Both third guide rails 63 extend along the first direction F. Thus, when the two third drive sliders 53 slide in engagement with the two third guide rails 63, the third curtain 30 unfolds or retracts approximately along the first direction F.

[0109] In this embodiment, reference continues to be made to... Figure 1 The drive assembly 70 includes a transmission member 72 and a movable member 73 that is driveably connected to the transmission member 72. The movable member 73 is correspondingly connected to the drive slider 50. The transmission member 72 is configured to drive the movable member 73 to move when rotating, thereby causing the drive slider 50 to move along the corresponding guide rail 60.

[0110] The transmission component 72 can be driven, for example, by connecting it to the motor 71.

[0111] In this embodiment, reference continues to be made to... Figure 1 The transmission component 72 includes a first pulley 81 located at the bottom of the first curtain 10, the moving component 73 includes two first drive ropes 731, and the drive assembly 70 also includes two first end auxiliary wheels 911 and two sets of first corner auxiliary wheels 912. Each set of first corner auxiliary wheels 912 includes at least two first corner auxiliary wheels 912. In addition, the first drive ropes 731 may be, for example, closed loops.

[0112] One first end auxiliary wheel 911 is disposed at the top of one first guide rail 61, and another first end auxiliary wheel 911 is disposed at the top of another first guide rail 61. One set of first corner auxiliary wheels 912 is disposed at the bottom of one first guide rail 61, and another set of first corner auxiliary wheels 912 is disposed at the bottom of another first guide rail 61. Each first drive rope 731 is correspondingly stretched on the first spool 81, one first end auxiliary wheel 911, and one set of first corner auxiliary wheels 912.

[0113] With this configuration, when the first pulley 81 rotates, the two first drive ropes 731 move under the drive of the first pulley 81, thereby driving the two first drive sliders 51 to move. It should be noted that since a first end auxiliary wheel 911 is located at the top of a first guide rail 61 and a first corner auxiliary wheel 912 is located at the bottom of a first guide rail 61, the first drive ropes 731 (stretched between the first pulley 81, the first end auxiliary wheel 911, and the first corner auxiliary wheel 912) Figure 1 The first drive rope 731 on the left side is arranged in an L-shape. Since another second end auxiliary wheel 921 is located at the top of another first guide rail 61, and another first corner auxiliary wheel 912 is located at the bottom of another first guide rail 61, the first drive rope 731 (stretched between the first pulley 81, the first end auxiliary wheel 911, and the first corner auxiliary wheel 912) is... Figure 1 The first drive rope 731 on the right side is arranged in an L-shape. It corresponds to the right and left sides of the first curtain 10, respectively, along with the first drive rope 731 on the left side.

[0114] For example, combined Figure 3 When the first pulley 81 rotates counterclockwise, segment a of the left first drive rope 731 is released and segment b is retracted; segment c of the right first drive rope 731 is retracted and segment d is released. The first drive slider 51 connected to segment a moves upward, and the first drive slider 51 connected to segment d also moves upward synchronously, causing the first curtain 10 to unfold. Conversely, when the first pulley 81 rotates clockwise, segment a of the left first drive rope 731 is retracted and segment b is released; segment c of the right first drive rope 731 is released and segment d is retracted. The first drive slider 51 connected to segment a moves downward, and the first drive slider 51 connected to segment d also moves downward synchronously, causing the first curtain 10 to close.

[0115] Additionally, it should be noted that each set of first corner auxiliary wheels includes two first corner auxiliary wheels 912. At the corner position, the two segments of the first drive rope 731 can be wound around the two first corner auxiliary wheels 912 respectively to achieve turning at the corner position.

[0116] Combination Figure 1 and Figure 4The transmission component 72 further includes a second reel 82 and a third reel 83, and the moving component 73 further includes two second drive ropes 732 and two third drive ropes 733. The drive assembly 70 further includes two second end auxiliary wheels 921 and two sets of second corner auxiliary wheels 922, as well as two third end auxiliary wheels 931 and two sets of third corner auxiliary wheels 932. Each set of second corner auxiliary wheels 922 includes at least two second corner auxiliary wheels 922, and each set of third corner auxiliary wheels 932 includes at least two third corner auxiliary wheels 932. Exemplarily, at least one of the second drive ropes 732 and the third drive ropes 733 can be a closed loop.

[0117] Two sets of second corner auxiliary wheels 922 are respectively located at the top of one of the second guide rails 62 and the top of the first side edge 411 of the rearview mirror area 410. The two sets of second corner auxiliary wheels 922 are also located at both ends of the second curtain 20 along the first direction F. Two second end auxiliary wheels 921 are respectively located at the bottom of one of the second guide rails 62 and the bottom of the first side edge 411 of the rearview mirror area 410.

[0118] Two sets of third corner auxiliary wheels 932 are respectively located at the top of one of the third guide rails 63 and the top of the second side edge 421 of the rearview mirror area 410. The two sets of third corner auxiliary wheels 932 are located at both ends of the third curtain 30 along the first direction F. Two third end auxiliary wheels 931 are respectively located at the bottom of one of the third guide rails 63 and the bottom of the second side edge 421 of the rearview mirror area 410.

[0119] Each second drive rope 732 is correspondingly stretched on the second reel 82, a second end auxiliary reel 921 and a set of second corner auxiliary reels 922, and each third drive rope 733 is correspondingly stretched on the third reel 83, a third end auxiliary reel 931 and a set of third corner auxiliary reels 932.

[0120] With this configuration, when the second pulley 82 rotates, the two second drive ropes 732 move under the drive of the second pulley 82, thereby driving the two second drive sliders 52 to move. It should be noted that since one second end auxiliary wheel 921 is located at the bottom of one second guide rail 62, and a set of second corner auxiliary wheels 922 are located at the top of one second guide rail 62, the second drive ropes 732 (stretched between the second pulley 82, the second end auxiliary wheel 921, and the second corner auxiliary wheel 922) Figure 4The second drive rope 732 on the left side is arranged in an L-shape. Since another second end auxiliary wheel 921 is located at the bottom end of the first side edge 411 of the rearview mirror area 410, and another set of second corner auxiliary wheels 922 is located at the top end of the first side edge 411 of the rearview mirror area 410, the second drive rope 732 (stretched on the second pulley 82, the second end auxiliary wheel 921, and the set of second corner auxiliary wheels 922) is L-shaped. Figure 4 The second drive rope 732 on the right side of the second reel 82 is arranged in an L-shape. It corresponds to the left and right sides of the second curtain 20, respectively, along with the second drive rope 732 on the left side.

[0121] The process of the second pulley 82 driving the second drive rope 732 and the process of the third pulley 83 driving the third drive rope 733 are similar to the process of the first pulley 81 driving the first drive rope 731, and will not be described again here.

[0122] Additionally, it should be noted that each set of second corner auxiliary wheels 922 includes two second corner auxiliary wheels 922. At the corner position, the two segments of the second drive rope 732 can be wound around the two second corner auxiliary wheels 922 respectively to achieve turning at the corner position. Similarly, each set of third corner auxiliary wheels 932 includes two third corner auxiliary wheels 932. At the corner position, the two segments of the third drive rope 733 can be wound around the two third corner auxiliary wheels 932 respectively to achieve turning at the corner position.

[0123] In the embodiments of this application, reference is made to Figure 5 and Figure 6 The drive assembly 70 also includes several auxiliary sliders 501 that slide with the guide rail 60. The second curtain 20, the third curtain 30 and the first curtain 10 are all connected to the auxiliary sliders 501. The auxiliary sliders 501 are movably disposed on the second drive rope 732, the third drive rope 733 and the first drive rope 731, and the auxiliary sliders 501 can slide relative to the corresponding second drive rope 732, the third drive rope 733 and the first drive rope 731.

[0124] In practice, the drive slider 50 and the corresponding curtain are fixedly connected, while the auxiliary slider 501 can move relative to the corresponding drive rope. For example, for Figure 6 As shown, the first curtain 10 retracts when the first drive rope 731 moves, causing the first drive slider 51 to move downwards. As it continues downwards, it contacts the first auxiliary slider 501 and continues downwards until the first curtain 10 is retracted. The drive slider 50 and each auxiliary slider 501 are stacked together. Each auxiliary slider 501 can move relative to the first drive rope 731 without interfering with the movement of the first drive rope 731.

[0125] The situation is similar for the second curtain 20 and the third curtain 30, and will not be described in detail here.

[0126] The following is combined with Figure 1 The working process of the sunshade device 100 of this application is described as follows: When the motor 71 connected to the first pulley 81 is started, it drives the first pulley 81 to rotate counterclockwise. For the first drive rope 731 on the left side of the first pulley 81, one end (b) is continuously wound around the pulley, while the other end (a) is continuously released, driving the first drive slider 51 on the left to rise. For the first drive rope 731 on the right side of the first pulley 81, one end (c) is continuously wound around the first pulley 81, while the other end (d) is continuously released, driving the first drive slider 51 on the right to rise. At this time, the first curtain 10, driven by the two first drive sliders 51, gradually rises along the first guide rail 61, causing the first curtain 10 to unfold.

[0127] To retract the first curtain 10, the first pulley 81 rotates clockwise, and the two first drive ropes 731 move in the opposite direction. Under the drive of the two first drive sliders 51, the first curtain 10 can gradually move downward along the first guide rail 61, thus retracting the first curtain 10.

[0128] The processes of the second deflector 82 driving the second curtain 20 to unfold and retract, and the processes of the third deflector 83 driving the third curtain 30 to unfold and retract, are similar to those of the first curtain 10 and will not be described in detail here.

[0129] In the embodiments of this application, reference is made to Figure 7 In another possible implementation, the transmission component 72 further includes a fourth pulley 84, and the moving component 73 further includes two closed-loop fourth drive ropes 734. The fourth pulley 84 is coaxially arranged with the first pulley 81, and the fourth pulley 84 and the first pulley 81 are used to connect to the same drive source. The drive source is, for example, an electric motor.

[0130] The drive assembly 70 also includes two fourth end auxiliary wheels 941 and six sets of fourth corner auxiliary wheels 942, wherein each set of fourth corner auxiliary wheels 942 includes at least two fourth corner auxiliary wheels 942.

[0131] Two fourth end auxiliary wheels 941 are respectively located at the bottom of the first side edge 411 and the bottom of the second side edge 421 of the rearview mirror area 410, that is, both fourth end auxiliary wheels 941 are located at the bottom of the rearview mirror area 410.

[0132] Three sets of fourth corner auxiliary wheels 942 are respectively installed at the top and bottom of one A-pillar and at the top of the first side edge 411 of the rearview mirror area 410. The other three sets of fourth corner auxiliary wheels 942 are respectively installed at the top and bottom of another A-pillar and at the top of the second side edge 421 of the rearview mirror area 410.

[0133] Each fourth drive rope 734 is correspondingly stretched on the fourth reel 84, a fourth end auxiliary reel 941, and three sets of fourth corner auxiliary reels 942.

[0134] It should be noted that, in this embodiment, the fourth reel 84 and the first reel 81 are as follows: Figure 8 As shown, it is a coaxial setup, driven by the same motor 71. Figure 7 In the example, for ease of observation, the fourth spool 84 and the first spool 81 are shown separately. Furthermore, the first spool 81 and the fourth spool 84 are stacked on top of each other along the axis of the first spool 81, and the winding diameter of the first spool 81 is larger than the winding diameter of the fourth spool 84.

[0135] With this configuration, the first curtain 10, the second curtain 20, and the third curtain 30 can be driven synchronously by a single motor 71.

[0136] Understandably, the strokes of the first drive rope 731 corresponding to the first curtain 10, the second drive rope 732 corresponding to the second curtain 20, and the third drive rope 733 corresponding to the third curtain 30 can be controlled by controlling the diameters of the first spool 81 and the fourth spool 84, thereby controlling the strokes of the first curtain 10, the second curtain 20, and the third curtain 30. The ratio of the stroke of the first curtain 10 to the strokes of the second curtain 20 and the third curtain 30 is equal to the ratio of the diameters of the first spool 81 and the fourth spool 84.

[0137] In this embodiment of the application, as another possible implementation, the transmission member 72 is configured as a gear and the moving member 73 is configured as a flexible shaft.

[0138] It should be noted that in this embodiment, the flexible shaft needs to be entirely housed within the guide rail 60 to guide its movement. Alternatively, in some other embodiments, the moving element 73 may be configured as a timing belt.

[0139] In this embodiment, reference continues to be made to... Figure 5 The second curtain 20, the third curtain 30 and the first curtain 10 are connected by Velcro, fasteners or magnetic attraction.

[0140] In a specific implementation, for example, a second pull rod 21 can be set on the second curtain 20, a third pull rod 31 can be set on the third curtain 30, and a first pull rod 11 can be set on the first curtain 10.

[0141] In this embodiment of the application, combined with Figure 1 and Figure 5Furthermore, one side of the first curtain 10 is fixed to the first pull rod 11, and two first drive sliders 51 are respectively connected to both ends of the first pull rod 11. One side of the second curtain 20 is fixed to the second pull rod 21, and two second drive sliders 52 are respectively connected to both ends of the second pull rod 21. One side of the third curtain 30 is fixed to the third pull rod 31, and two third drive sliders 53 are respectively connected to both ends of the third pull rod 31. This causes the corresponding drive sliders 50 to drive the corresponding pull rods to move, thereby causing the corresponding curtains to unfold or retract.

[0142] The second pull rod 21, the third pull rod 31, and the first pull rod 11 may all have a magnetic attraction structure inside, and adjacent second pull rods 21 and first pull rods 11, and third pull rods 31 and first pull rods 11 are connected by magnetic attraction.

[0143] Additionally, refer to Figure 9 Regarding the structure of the guide rail 60, for example, the first guide rail 61 may also include an extension 64. The sliding track on the first guide rail 61 can extend to the extension 64, and the extension 64 can be accommodated in the space inside the center console, that is, the extension 64 is hidden under the center console, and is used to store the first curtain 10 when it is closed. In this way, when the first drive slider 51 moves downward to the extension 64, if the center console has a notch corresponding to the position of the first curtain 10, the first curtain 10 can be stored in the space inside the center console through the notch. The length of the extension 64 can be set to, for example, 50mm. It should be noted that the guide rail 60 with this structure can be applied to, for example, Figure 1-8 The illustrated sunshade device 100.

[0144] Reference Figure 10 As another possible implementation, the second curtain 20, the third curtain 30 and the first curtain 10 are all provided with rollers, and the drive slider 50 is configured to move along the guide rail 60 to drive the second curtain 20, the third curtain 30 and the first curtain 10 to unfold or rewind on the corresponding rollers.

[0145] In a specific implementation, the sunshade device 100 may include a first roller 12, a second roller 22, and a third roller 32. The first curtain 10 can be wound onto the first roller 12 or unwound from the first roller 12 under the action of the first drive slider 51. The second curtain 20 can be wound onto the second roller 22 or unwound from the second roller 22 under the action of the second drive slider 52. The third curtain 30 can be wound onto the third roller 32 or unwound from the third roller 32 under the action of the third drive slider 53. Of course, elastic elements such as coil springs can be respectively provided on the first roller 12, the second roller 22, and the third roller 32, so as to facilitate the winding of the first curtain 10, the second curtain 20, and the third curtain 30.

[0146] This application embodiment also provides a glass assembly, including the sunshade device 100 as described above. The glass assembly also includes a glass element, such as a windshield 40, and a rearview mirror area 410 is disposed on the glass element. The sunshade device 100 is disposed opposite to the glass element, and the upper section curtain 101 and the lower section curtain 102 are used to cover the glass element.

[0147] This application also provides a vehicle including the sunshade device 100 as described above. The structure and implementation principle of the sunshade device 100 have been described in detail above and will not be repeated here.

[0148] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
