Description

Technical Field

[0001] The present invention relates to the technical field of automobiles, and in particular to a sunshade device, a glass assembly and a vehicle. Background Art

[0002] With the increasing popularity of cars, people are paying more and more attention to car maintenance. Exposing a car to the sun for extended periods of time can accelerate the aging of internal components, increase the temperature inside the car, and release harmful substances from certain materials, potentially endangering human health. Sunshades are auxiliary products used for sun protection in cars. By shielding the car's windows from the inside, they reduce the amount of sunlight directly entering the car, thereby alleviating the harmful effects of sun exposure. Related art sunshade devices include a sunshade, a linkage mechanism, and a drive mechanism. The sunshade consists of two left and right panels, each positioned inside the front windshield, extending from the top to the bottom to block the windshield. The two panels are located on either side of the rearview mirror area, respectively. The drive mechanism drives the linkage mechanism to move the top ends of the two panels up and down to retract or deploy the sunshades.

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

[0082] exist Figure 1 In the example, for easy observation, Figure 1 The figure on the upper side of the middle figure shows an example with the drive assembly 70 omitted. Figure 1 The figure on the lower side of the middle figure omits the first curtain 10 , the second curtain 20 , and the third curtain 30 for illustration.

[0083] Reference Figure 1 The sunshade device 100 provided in the embodiment of the present application includes an upper partition curtain 101, a lower partition curtain 102 and a drive assembly 70. The drive assembly 70 is configured to drive the upper partition curtain 101 and the lower partition curtain 102 to expand or retract. The upper partition curtain 101 is used to be arranged at least on the side of the rearview mirror area 410, and the lower partition curtain 102 is used to be arranged 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 pieced together into a whole to be arranged around the rearview mirror area 410. In the embodiment of the present application, in use, the upper partition curtain 101 can be arranged on the upper side of the lower partition curtain 102.

[0084] By setting the upper partition curtain 101, the lower partition curtain 102 and the driving component 70, the driving component 70 is configured to drive the upper partition curtain 101 and the lower partition curtain 102 to expand or retract. As long as the driving component 70 is used for driving, the upper partition curtain 101 and the lower partition curtain 102 can be expanded or retracted, and the sunshade state and non-sunshade state of the sunshade curtain device 100 can be switched, and the operation is relatively simple and convenient. In addition, the upper partition curtain 101 is used to be set at least on the side of the rearview mirror area 410, and the lower partition curtain 102 is used to be set 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 pieced together into a whole to be used to surround the rearview mirror area 410. When the upper partition curtain 101 and the lower partition curtain 102 are unfolded, they can at least cover the area around the rearview mirror area 410 from the bottom side and 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 shading effect of the sunshade device 100.

[0085] In this embodiment of the present application, 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 arranged 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 deployed, they are combined into a single unit and are arranged to surround the rearview mirror area 410, where the first direction F is the width of the vehicle. Here, the first curtain 10 is located at the bottom side of the rearview mirror area 410 and can therefore 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 respectively located on the left and right sides of the rearview mirror area 410, and the first curtain 10 is located on the lower side of the rearview mirror area 410, which can surround the rearview mirror area 410 on the left, right and lower sides, avoiding the existence of light leakage areas around the rearview mirror area 410, and can improve the shading effect of the sunshade device 100.

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

[0087] The first curtain 10 , the second curtain 20 and the third curtain 30 are each correspondingly 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 each connected to the corresponding driving slider 50 .

[0088] Furthermore, the driving assembly 70 is connected to the driving sliders 50 corresponding to the first curtain 10, the second curtain 20 and the third curtain 30, and the driving assembly 70 is used to drive the driving sliders 50 to move along the corresponding guide rails 60 to expand or fold the first curtain 10, the second curtain 20 and the third curtain 30.

[0089] The first curtain 10, the second curtain 20, and the third curtain 30 are each provided with at least one set of driving sliders 50 and guide rails 60, and are connected to the corresponding driving sliders 50. Therefore, when the driving sliders 50 move along the guide rails 60, the curtains connected to the driving sliders 50 can be driven to move along the extension direction of the guide rails 60.

[0090] The drive assembly 70 is connected to the drive sliders corresponding to the first curtain 10, the second curtain 20, and the third curtain 30, and is used to drive the drive sliders 50 corresponding to the first curtain 10, the second curtain 20, and the third curtain 30 to move along the corresponding guide rails 60, so as to expand or retract the first curtain 10, the second curtain 20, and the third curtain 30. Therefore, as long as the drive sliders 50 are driven by the drive assembly 70 to move along the corresponding guide rails 60, the first curtain 10, the second curtain 20, and the third curtain 30 can be expanded or retracted.

[0091] In the embodiment of the present application, the first curtain 10, the second curtain 20, and the third curtain 30 can be elastic curtains or other flexible materials, for example, they can be high-precision blackout cloths, which can be coated with reflective materials such as silver fabrics.

[0092] When deployed, the first, second, and third curtains 10, 20, and 30 should be able to completely cover the front windshield 40. The outer contours of the first, second, and third curtains 10, 20, and 30 should, on the one hand, completely match and conform to the outer contour of the rearview mirror area 410, and on the other hand, be substantially the same as the outer contour of the front windshield 40. Furthermore, the outer contour edge of the first, second, and third curtains 10, 20, and 30 combined should be located outside the outer contour edge of the front windshield 40.

[0093] 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. In the embodiment of the present application, the first curtain 10 corresponds to two driving sliders 50 and a guide rail 60, and the first curtain 10 is connected to the corresponding two driving sliders 50. The second curtain 20 corresponds to two driving sliders 50 and a guide rail 60, and the second curtain 20 is connected to the corresponding two driving sliders 50. The third curtain 30 corresponds to two driving sliders 50 and a guide rail 60, and the third curtain 30 is connected to the corresponding two driving sliders 50 as an example for description.

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

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

[0096] In this way, when the two first driving sliders 51 are driven respectively, the two sides of the first curtain 10 along the first direction F can be driven to move along the extending direction of the first guide rail 61 .

[0097] The extension direction of each first guide rail 61 can be determined based on the extension direction of the A-pillar to which it is connected. For example, when the two A-pillars are tilted and located at the two waists of a trapezoid, the two first guide rails 61 are also located at the two waists of the trapezoid. The bottom end of the first curtain 10 can be fixedly connected to the intersection of the vehicle's front windshield 40 and the center console. The two first drive sliders 51 can be respectively located at the top end of the first curtain 10. This facilitates the movement of the top end of the first curtain 10 when the first drive slider 51 slides, causing the first curtain 10 to expand or retract.

[0098] In the present application, continue to refer to Figure 1 The second curtain 20 and the third curtain 30 are respectively arranged on opposite sides of the rearview mirror area 410 along the first direction F, and the second curtain 20 and the third curtain 30 each correspond to two driving sliders 50 and guide rails 60.

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

[0100] In the embodiment of the present application, Figure 1 As shown, the 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 the 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] Or in some other embodiments, 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 embodiment of this application, Figure 1In the example shown in the upper figure, the second and third curtains 20 and 30 can be positioned no lower than the bottom of the rearview mirror area 410 along the height of the front windshield 40, while the first curtain 10 can be positioned no higher than the bottom of the rearview mirror area 410 along the height of the front windshield 40. In fact, when the first, second, and third curtains 10, 20, and 30 are deployed, the bottom ends of the second and third curtains 20, 30, and the top end of the first curtain 10 intersect collinearly with the bottom edge of the rearview mirror area 410. Thus, when deployed, the first, second, and third curtains 10, 20, and 30 can completely block the entire perimeter of the rearview mirror area 410.

[0103] exist Figure 1 In the illustrated embodiment, one of the two second guide rails 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 slidably engage the two second guide rails 62, the second curtain 20 deploys or retracts substantially along the height direction of the front windshield 40. Furthermore, this allows for better adaptation to different vehicle models, even when the rearview mirror area 410 is located in a different position.

[0104] In this embodiment, since the first, second, and third curtains 10, 20, and 30 are arranged in separate areas and independently controlled, and since they all move in the vertical direction, interference with driving operations can be avoided. In addition, the second and third curtains 20, 30 are positioned at the top of the front windshield 40, functioning as sun visors.

[0105] Of the two third guide rails 63, one extends along the extension direction of the other A-pillar (e.g., the A-pillar on the right side of the drawing) and is integrally connected to the other 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 driving sliders 53 slidably engage the two third guide rails 63, the third curtain 30 is deployed or retracted substantially along the height direction of the front windshield 40.

[0106] In the embodiment of the present application, the first guide rail 61 and the second guide rail 62 connected to one A-pillar are constructed as an integral structure, while the first guide rail 61 and the third guide rail 63 connected to the other A-pillar are constructed as an integral structure. This facilitates manufacturing and installation. In other embodiments, the first guide rail 61 and the second guide rail 62 connected to one A-pillar may be constructed as a separate structure, while the first guide rail 61 and the third guide rail 63 connected to the other A-pillar may also be constructed as a separate structure.

[0107] In the embodiment of this application, Figure 2 In the illustrated example, two second guide rails 62 are spaced apart along the extension direction of the A-pillars. 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 together with the two second guide rails 62, the second curtain 20 is generally extended or retracted along the first direction F.

[0108] The two third guide rails 63 are spaced apart along the extension direction of the A-pillars. One end of each third guide rail 63 is connected to another 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 slidably engage the two third guide rails 63, the third curtain 30 is generally extended or retracted along the first direction F.

[0109] In the present application, continue to refer to Figure 1 The driving assembly 70 includes a transmission member 72 and a moving member 73 connected to the transmission member 72, and the moving member 73 is connected to the driving slider 50. The transmission member 72 is configured to drive the moving member 73 to move when rotating, so as to drive the driving slider 50 to move along the corresponding guide rail 60.

[0110] The transmission member 72 can be driven by being connected to the motor 71 , for example.

[0111] In the present application, continue to refer to Figure 1 The transmission member 72 includes a first pulley 81 disposed at the bottom of the first curtain 10. The moving member 73 includes two first drive ropes 731. 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 can be, for example, in the form of a closed loop.

[0112] One of the first end auxiliary wheels 911 is configured to be installed at the top of one first guide rail 61, and the other first end auxiliary wheel 911 is configured to be installed at the top of the other first guide rail 61. One set of first corner auxiliary wheels 912 is configured to be installed at the bottom of one first guide rail 61, and the other set of first corner auxiliary wheels 912 is configured to be installed at the bottom of the other first guide rail 61. Each first drive rope 731 is correspondingly stretched over the first pulley 81, one of the first end auxiliary wheels 911, and one of the first corner auxiliary wheels 912.

[0113] With this arrangement, when the first spool 81 rotates, the two first driving ropes 731 are driven by the first spool 81 to move, respectively driving the two first driving sliders 51 to move. It should be noted that since a first end auxiliary wheel 911 is provided at the top end of a first guide rail 61 and a first corner auxiliary wheel 912 is provided at the bottom end of a first guide rail 61, the first driving rope 731 ( Figure 1 The first driving rope 731 on the left side is arranged in an L shape. Since the other second end auxiliary wheel 921 is arranged at the top end of the other first guide rail 61, and the other first corner auxiliary wheel 912 is arranged at the bottom end of the other first guide rail 61, the first driving rope 731 ( Figure 1 The first driving 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 with the first driving rope 731 on the left side.

[0114] For example, in combination Figure 3 When the first pulley 81 rotates counterclockwise, section a of the left first driving rope 731 is released and section b is retracted, and section c of the right first driving rope 731 is retracted and section d is released. The first driving slider 51 connected to section a moves upward, and the first driving slider 51 connected to section d also moves upward synchronously, so that the first curtain 10 is unfolded. Conversely, when the first pulley 81 rotates clockwise, section a of the left first driving rope 731 is retracted and section b is released, and section c of the right first driving rope 731 is released and section d is retracted, the first driving slider 51 connected to section a moves downward, and the first driving slider 51 connected to section d also moves downward synchronously, so that the first curtain 10 is retracted.

[0115] In addition, 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 rope segments of the first drive rope 731 can be respectively wound around the two first corner auxiliary wheels 912 to achieve steering at the corner position.

[0116] Combine Figure 1 and Figure 4The transmission member 72 further includes a second pulley 82 and a third pulley 83, and the moving member 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. A set of second corner auxiliary wheels 922 includes at least two second corner auxiliary wheels 922, and a set of third corner auxiliary wheels 932 includes at least two third corner auxiliary wheels 932. Exemplarily, at least one of the second drive rope 732 and the third drive rope 733 may be in a closed loop.

[0117] The two sets of second corner auxiliary wheels 922 are respectively arranged at the top end of one of the second guide rails 62 and the top end 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. The two second end auxiliary wheels 921 are respectively arranged at the bottom end of one of the second guide rails 62 and the bottom end of the first side edge 411 of the rearview mirror area 410.

[0118] The two sets of third corner auxiliary wheels 932 are respectively arranged at the top end of one of the third guide rails 63 and the top end 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. The two third end auxiliary wheels 931 are respectively arranged at the bottom end of one of the third guide rails 63 and the bottom end of the second side edge 421 of the rearview mirror area 410.

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

[0120] With this arrangement, when the second wire wheel 82 rotates, the two second driving ropes 732 are driven by the second wire wheel 82 to move, respectively driving the two second driving sliders 52 to move. It should be noted that since a second end auxiliary wheel 921 is provided at the bottom end of a second guide rail 62, and a set of second corner auxiliary wheels 922 are provided at the top end of a second guide rail 62, the second driving ropes 732 ( Figure 4The second driving rope 732 on the left side is arranged in an L shape. Since the other second end auxiliary wheel 921 is arranged at the bottom end of the first side edge 411 of the rearview mirror area 410, and the other set of second corner auxiliary wheels 922 is arranged at the top end of the first side edge 411 of the rearview mirror area 410, the second driving rope 732 ( Figure 4 The second driving rope 732 on the right side of the second pulley 82 is arranged in an L-shape. And the second driving rope 732 on the left side corresponds to the left and right sides of the second curtain 20 respectively.

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

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

[0123] In the present application, refer to Figure 5 and Figure 6 The driving assembly 70 also includes a number of 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 with the auxiliary sliders 501. The auxiliary sliders 501 are movably arranged on the second driving rope 732, the third driving rope 733 and the first driving rope 731, and the auxiliary sliders 501 can slide relative to the corresponding second driving rope 732, the third driving rope 733 and the first driving rope 731.

[0124] In a specific implementation, the driving slider 50 and the corresponding curtain are fixedly connected, while the auxiliary slider 501 can move relative to the corresponding driving rope. Figure 6 The first curtain 10 shown, when the first driving rope 731 moves, drives the first driving slider 51 to move downward, and the first curtain 10 is retracted. In this way, as it continues to move downward, it contacts the first auxiliary slider 501 and continues to move downward until the first curtain 10 is retracted. The driving slider 50 and each auxiliary slider 501 are stacked up, wherein each auxiliary slider 501 can move relative to the first driving rope 731 without interfering with the movement of the first driving rope 731.

[0125] The situations of the second curtain 20 and the third curtain 30 are similar and will not be described in detail here.

[0126] The following combination Figure 1 The operating process of the sunshade device 100 of the present application is described below. 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 by the pulley while the other end (a) is continuously released, driving the first drive slider 51 on the left side to rise. For the first drive rope 731 on the right side of the first pulley 81, one end (c) is continuously wound by the first pulley 81 while the other end (d) is continuously released, driving the first drive slider 51 on the right side to rise. At this time, the first curtain 10, driven by the two first drive sliders 51, gradually moves upward 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 driving ropes 731 move in the opposite direction. The first curtain 10 can be driven by the two first driving sliders 51 to gradually move downward along the first guide rail 61 , so that the first curtain 10 is retracted.

[0128] The process of the second pulley 82 driving the second curtain 20 to unfold and retract, and the process of the third pulley 83 driving the third curtain 30 to unfold and retract are similar to those of the first curtain 10 and will not be repeated here.

[0129] In the present application, refer to Figure 7 In another possible implementation, the transmission member 72 further includes a fourth pulley 84, and the moving member 73 further includes two closed-loop fourth drive ropes 734. The fourth pulley 84 is coaxially disposed with the first pulley 81, and the fourth pulley 84 and the first pulley 81 are configured to be connected to the same drive source, such as a motor.

[0130] The drive assembly 70 further 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] The two fourth end auxiliary wheels 941 are respectively disposed at the bottom ends of the first side edge 411 and the second side edge 421 of the rearview mirror area 410 , that is, the two fourth end auxiliary wheels 941 are both located at the bottom of the rearview mirror area 410 .

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

[0133] Each fourth driving rope 734 is correspondingly stretched on the fourth line wheel 84, a fourth end auxiliary wheel 941 and three sets of fourth corner auxiliary wheels 942.

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

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

[0136] It can be understood that 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 pulley 81 and the fourth pulley 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 stroke of the second curtain 20 and the stroke of the third curtain 30 is equal to the ratio of the diameter of the first pulley 81 to the diameter of the fourth pulley 84.

[0137] In the embodiment of the present 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 accommodated in the guide rail 60 to guide the movement of the flexible shaft. Alternatively, in other embodiments, the moving member 73 may also be configured as a synchronous belt.

[0139] In the present application, continue to refer to Figure 5 The second curtain 20, the third curtain 30 and the first curtain 10 are connected by Velcro, button fasteners or magnetic attraction.

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

[0141] In the embodiment of this application, Figure 1 and Figure 5Furthermore, one side of the first curtain 10 is fixed to the first pull rod 11, and the two ends of the first pull rod 11 are respectively connected to two first driving sliders 51. One side of the second curtain 20 is fixed to the second pull rod 21, and the two ends of the second pull rod 21 are respectively connected to two second driving sliders 52. One side of the third curtain 30 is fixed to the third pull rod 31, and the two ends of the third pull rod 31 are respectively connected to two third driving sliders 53. Therefore, the corresponding driving slider 50 drives the corresponding pull rod to move, thereby driving the corresponding curtain to expand or retract.

[0142] The second pull rod 21 , the third pull rod 31 , and the first pull rod 11 may all be provided with a magnetic structure therein, and the adjacent second pull rod 21 and the first pull rod 11 , and the third pull rod 31 and the first pull rod 11 are connected by magnetic attraction.

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

[0144] Reference Figure 10 As another possible embodiment, the second curtain 20, the third curtain 30 and the first curtain 10 are all provided with a winding shaft, and the driving slider 50 is configured to move along the guide rail 60, so as to drive the second curtain 20, the third curtain 30 and the first curtain 10 to unfold or reel in on the corresponding winding shaft.

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

[0146] The present application also provides a glass assembly including the sunshade device 100 described above. The glass assembly also includes a glass member, such as a front windshield 40, with a rearview mirror region 410 disposed on the glass member. The sunshade device 100 is disposed opposite the glass member, and an upper partitioned curtain 101 and a lower partitioned curtain 102 are used to shield the glass member.

[0147] The embodiment of the present application further provides a vehicle, comprising 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 above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
