Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a sunshade device and a vehicle. Background Technology

[0002] In hot weather, sunlight can easily stream directly into the car through the windshield. As the sunlight penetrates the cabin, heat accumulates, and the temperature gradually rises. Some instruments and interior components are easily damaged in high temperatures. To prevent sunlight from directly entering the car through the windshield, users typically use a sunshade to cover the windshield and block the sunlight.

[0003] In related technologies, a vehicle sunshade device has been proposed, which includes a roller and a sunshade curtain. The sunshade curtain has a fixed end and a movable end. The fixed end of the sunshade curtain is connected to the roller, and the sunshade curtain can be wound around the outside of the roller. The user can pull the sunshade curtain to unfold it and block sunlight. In practical applications, the user needs to manually pull the sunshade curtain to unfold it, which is inconvenient to use.

[0004] In other related technologies, a sunshade roller shutter for automotive windshields has been proposed. This roller shutter includes a main body fixed to the A-pillar guard on one side of the vehicle. The main body includes a central pivot, a sunshade cloth, and a connecting plate. One end of the sunshade cloth is fixedly connected to the central pivot, and the other end is fixedly connected to the connecting plate. The sunshade cloth is wound around the central pivot. However, in practical applications, the sunshade cloth of this automotive windshield roller shutter still requires manual opening by the user, which is inconvenient. Summary of the Invention

[0005] One objective of this invention is to provide a sunshade device to solve the problem that existing sunshades are inconvenient to use. A second objective of this invention is to provide a vehicle.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] On one hand, this application provides a sunshade device, including a fixing member, a sunshade curtain, a driving component, a guide component, and a drive component. One end of the sunshade curtain is connected to the fixing member. The driving component is connected to the other end of the sunshade curtain. The driving component and the guide component are slidably connected along the extending direction of the guide component. The drive component is connected to the driving component and is used to drive the driving component to slide along the extending direction of the guide component.

[0008] According to the above technical means, in practical application, the fixing component can be located at one end of the windshield and connected to the front pillar. The guide component can be arranged parallel to the windshield and extend away from the fixing component. Thus, the driving component, driven by the drive assembly, can move from the end of the guide component near the fixing component to the end of the guide component away from the fixing component, thereby moving from one end of the windshield to the other end. With the movement of the driving component, the other end of the sunshade can simultaneously move from one end of the windshield to the other, allowing the sunshade to be converted to an unfolded state. After unfolding, the two ends of the sunshade are located at opposite ends of the windshield, thus providing shading. The driving component, driven by the drive assembly, can move from the end of the guide component away from the fixing component to the end of the guide component near the fixing component, thereby moving the end of the sunshade connected to the driving component towards the fixing component to retract the sunshade. Users do not need to manually open the sunshade; the sunshade device can automatically open the sunshade to block sunlight from the outside environment, or automatically retract the sunshade to avoid obstructing the user's view, making it convenient for consumers to use.

[0009] In one possible implementation, the guiding assembly includes a first guide member and a second guide member. The second guide member is spaced apart from the first guide member along the extending direction of the fixing member. One end of the driving assembly is slidably connected to the first guide member, and the other end is slidably connected to the second guide member.

[0010] According to the above-mentioned technical means, the first guide and the second guide can guide both ends of the driving component, thereby ensuring the smooth movement of the driving component.

[0011] In one possible implementation, the driving assembly includes a first driving member and a second driving member. The first driving member is connected to the sunshade and also to the drive assembly. One end of the first driving member is slidably connected to a first guide member, and the other end extends toward the second guide member. The second driving member is connected to the sunshade and also to the drive assembly. One end of the second driving member is slidably connected to the second guide member, and the other end extends toward the first guide member. The first and second driving members are spaced apart along the extension direction of the fixing member.

[0012] According to the aforementioned technical means, the first driving member can have a large connection space along the width direction of the sunshade, allowing the sunshade to fully connect with the first driving member in the width direction. This reduces wrinkles at the end of the sunshade connected to the first driving member during its ascent, thereby improving the flatness of the sunshade after it is unfolded. Similarly, the second driving member can also have a large connection space along the width direction of the sunshade, allowing the sunshade to fully connect with the second driving member in the width direction. This also reduces wrinkles at the end of the sunshade connected to the second driving member during its ascent, further improving the flatness of the sunshade after it is unfolded. The first and second driving members can be spaced apart in the width direction of the windshield to avoid obstructing certain components located in the center of the windshield.

[0013] In one possible implementation, the sunshade includes a first curtain body, a second curtain body, and a third curtain body. Along the extending direction of the fastener, the second curtain body is located on one side of the first curtain body and connected to it. Along the extending direction of the fastener, the third curtain body is located on the side of the second curtain body away from the first curtain body and connected to it. The first curtain body is connected to a first actuating member, and the third curtain body is connected to a second actuating member. The second curtain body is an elastic curtain body.

[0014] Based on the aforementioned technical methods, the width of the windshield typically decreases gradually from bottom to top. Correspondingly, the distance between the two front pillars also gradually decreases from bottom to top. Because the second curtain is elastic, it can be in a stretched state when the sunshade is at the bottom of the windshield. As the sunshade rises, the end of the second curtain closest to the windshield gradually returns to its original position. This avoids large wrinkles in the middle of the sunshade, ensuring a good fit between the sunshade and the windshield.

[0015] In one possible implementation, a first guide member is provided with a first sliding portion, and a second guide member is provided with a second sliding portion. A first driving member includes a first sliding member and a first driving member body. The first sliding member is slidably connected to the first sliding portion. One end of the first driving member body is connected to the first sliding member, and the other end extends towards the second guide member and connects to the first curtain. The second driving member includes a second sliding member and a second driving member body. The second sliding member is slidably connected to the second sliding portion. One end of the second driving member body is connected to the second sliding member, and the other end extends towards the first guide member and connects to the third curtain.

[0016] According to the above-mentioned technical means, the first sliding part can guide the first sliding member, thereby allowing the first sliding member and the main body of the first driving member to slide along the first sliding part. The second sliding part can guide the second sliding member, thereby allowing the second sliding member and the second driving member to slide along the second sliding part.

[0017] In one possible implementation, the first sliding portion is a first sliding groove, and the first sliding member is inserted into the first sliding groove. The second sliding portion is a second sliding groove, and the second sliding member is inserted into the second sliding groove.

[0018] According to the above technical means, during the sliding process of the first sliding member along the first sliding groove, the side wall of the first sliding groove can limit the sliding member, thereby guiding the sliding of the first sliding member. Similarly, the inner wall of the second sliding groove can also limit the sliding member, thereby guiding the sliding of the second sliding member.

[0019] In one possible implementation, a first limiting groove is formed on the side wall of the first sliding groove, and a second limiting groove is provided on the first sliding member, with the second limiting groove being disposed opposite to the first limiting groove. The guide assembly also includes a first sliding limiting member. A portion of the first sliding limiting member is inserted into the first limiting groove and slidably connected to it, while the other portion is inserted into the second limiting groove. Along a direction perpendicular to the plane where the opening of the first sliding groove is located, the first sliding limiting member abuts against the inner walls of both the first and second limiting grooves.

[0020] According to the above technical means, the first sliding limiter can restrict the first sliding member, preventing it from falling out of the first sliding groove from the opening, thereby ensuring that the first sliding member can slide stably along the first sliding groove. The second sliding limiter can restrict the second sliding member, preventing it from falling out of the second sliding groove from the opening, thereby ensuring that the second sliding member can slide stably along the second sliding groove.

[0021] On the other hand, this application also provides a vehicle including the aforementioned sunshade device.

[0022] Since the vehicle provided in this application includes the sunshade device proposed in the first aspect, it can solve the same technical problems as the sunshade device described above and achieve the same technical effects, it will not be described again here.

[0023] In one possible implementation, the vehicle further includes a vehicle body, a windshield, and two front pillars. The windshield is connected to the vehicle body. The two front pillars are connected to the vehicle body and are spaced apart at opposite ends of the windshield. A fastener extends along the spacing direction of the two front pillars and is connected to the vehicle body. A guide assembly is connected to the front pillars and extends along the extension direction of the front pillars.

[0024] Based on the aforementioned technical means, the guide component can be designed according to the curvature of the windshield, so that the sunshade can fit better against the windshield. In this way, the sunshade provides better shading for the windshield, and when unfolded, it fits the windshield more closely, resulting in a more aesthetically pleasing overall appearance.

[0025] In one possible implementation, the vehicle further includes a pillar trim panel. The pillar trim panel is connected to the front pillar, and a receiving cavity is provided on the side of the pillar trim panel near the front pillar. A guide assembly is disposed within the receiving cavity. A guide opening communicating with the receiving cavity is provided on the pillar trim panel, allowing the drive assembly to pass through the guide opening and slide in connection with the guide assembly.

[0026] Based on the aforementioned technical means, the receiving cavity can shield the guide assembly, thereby improving the overall aesthetics of the vehicle interior. Simultaneously, the receiving cavity can also protect the guide assembly. The guide opening can avoid the drive assembly, allowing the drive assembly to slide smoothly with the guide assembly.

[0027] In one possible implementation, the guide opening is located on the side of the pillar trim closer to the windshield.

[0028] Based on the aforementioned technical means, the portion of the pillar interior trim closest to the cabin can be a flat surface, ensuring the appearance of the vehicle's interior.

[0029] In one possible implementation, the distance between the two front posts near the fixing member is greater than the distance between the two front posts away from the fixing member.

[0030] According to the aforementioned technical means, the distance between the first guide member and the second guide member connected to the two front pillars can also be gradually reduced from bottom to top. When the first driving member and the second driving member drive the sunshade to move, the distance between the first driving member and the second driving member can be adjusted according to the width of the windshield so that the sunshade can cover the windshield.

Detailed Implementation

[0040] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0041] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0042] This application provides a vehicle, which may include a vehicle body and a sunshade device. The sunshade device may be installed on the vehicle body to block sunlight from entering the vehicle body.

[0043] like Figure 1 As shown, Figure 1 This is a partial structural diagram of the vehicle 200 and the sunshade device 100 provided in an embodiment of this application. The vehicle 200 may include a windshield 210. The windshield 210 is connected to the vehicle body. In this way, the windshield 210 can be fixed to the vehicle body.

[0044] Continue to refer to Figure 1The vehicle 200 may also include front pillars 220. It is understood that there can be two front pillars 220, which can be connected to the vehicle body and positioned opposite each other at both ends of the windshield 210. Specifically, the two front pillars 220 can be positioned along the width of the windshield 210 at both ends of the windshield 210.

[0045] In practical applications, the front pillar 220 can improve the overall rigidity of the vehicle 200, thereby enhancing the safety of passengers riding in the vehicle 200. Furthermore, along the width direction of the vehicle 200, the front pillar 220 can provide support for both ends of the windshield 210, thereby improving the stability of the windshield 210.

[0046] It is understood that the vehicle provided in this application embodiment may also include other components, such as an engine, transmission mechanism, etc., to realize the basic functions of the vehicle.

[0047] Next, the sunshade device 100 provided in the embodiments of this application will be further described. For example... Figure 2 As shown, Figure 2 This is a schematic diagram of the structure of the sunshade device 100 provided in the embodiments of this application. The sunshade device 100 may include a fixing member 1 and a sunshade curtain 2. One end of the sunshade curtain 2 is connected to the fixing member 1.

[0048] Continue to refer to Figure 2 The sunshade device 100 may further include a drive assembly 3, a guide assembly 4, and a driving assembly 5. The drive assembly 3 is connected to the other end of the sunshade curtain 2. The drive assembly 3 is slidably connected to the guide assembly 4 along the extending direction of the guide assembly 4. The driving assembly 5 is connected to the drive assembly 3 and is used to drive the drive assembly 3 to slide along the extending direction of the guide assembly 4.

[0049] In practical applications, the fastener 1 can be located at the front windshield 210 ( Figure 1 One end of ) is connected to the front pillar 220 ( Figure 1 The guide assembly 4 can be arranged parallel to the windshield 210 and extend away from the fixing member 1. In this way, the drive assembly 3 can move from the end of the guide assembly 4 near the fixing member 1 to the end of the guide assembly 4 away from the fixing member 1 under the drive of the drive assembly 5, thereby moving from one end of the windshield 210 to the other end of the windshield 210.

[0050] Understandably, as the drive component 3 moves, the other end of the sunshade 2 can move synchronously from one end of the windshield 210 to the other, allowing the sunshade 2 to be switched to an unfolded state. After unfolding, the two ends of the sunshade 2 are located at opposite ends of the windshield 210, thus providing shading to the windshield 210.

[0051] Driven by the drive component 5, the drive component 3 can move from the end of the guide component 4 away from the fixing member 1 to the end of the guide component 4 close to the fixing member 1, thereby driving the end of the sunshade curtain 2 connected to the drive component 3 to move closer to the fixing member 1, so as to retract the sunshade curtain 2.

[0052] In this way, the user does not need to manually open the sunshade 2. The sunshade device 100 can automatically open the sunshade 2 so that the sunshade 2 can block the sunlight from the outside environment, or automatically retract the sunshade 2 to avoid the sunshade 2 affecting the user's vision and make it convenient for the user to use.

[0053] Specifically, such as Figure 1 and Figure 2 As shown, the fastener 1 can extend along the interval direction of the two front pillars 220 and connect to the vehicle body. The guide assembly 4 can connect to the front pillars 220 and extend along the extension direction of the front pillars 220. In this way, when the sunshade 2 is unfolded, it can provide a good shading effect on the windshield 210.

[0054] In practical applications, the guide component 4 can be designed according to the curvature of the windshield 210 so that the sunshade 2 can fit well with the windshield 210. In this way, the sunshade 2 has a good shading effect on the windshield 210, and the sunshade 2 fits well with the windshield 210 after being unfolded, and its overall shape is more aesthetically pleasing.

[0055] In order to enable the driving component 5 to drive the driving component 3 to move, in some embodiments, such as Figure 2 As shown, the drive assembly 5 may include a drive motor 51, a transmission component 52, a flexible shaft 53, and a limiting component 54. The drive motor 51 is connected to the transmission component 52, and the flexible shaft 53 is also connected to the transmission component 52. One end of the flexible shaft 53 is connected to the drive assembly 3. The flexible shaft 53 is used to move under the drive of the transmission component 52, thereby driving the drive assembly 3 to move along the guide assembly 4. The limiting component 54 is slidably connected to the flexible shaft 53.

[0056] In practical applications, the limiting member 54 can limit the movement direction of the flexible shaft 53, so that the end of the flexible shaft 53 connected to the driving component 3 can move along the extension direction of the guide component 4, thereby facilitating the movement of the flexible shaft 53 and the driving component 3.

[0057] For example, such as Figure 2 As shown, the transmission component 52 may include a limiting housing and a transmission gear, which is connected to the output end of the drive motor 51. The flexible shaft 53 passes through the limiting housing.

[0058] The flexible shaft 53 can be a bendable transmission rod, and its surface can be provided with transmission tooth grooves that can mesh with transmission gears. In this way, the transmission gears can drive the flexible shaft 53 to move as they rotate under the drive of the drive motor 51.

[0059] In some embodiments, such as Figure 3 As shown, Figure 3 This is a partial cross-sectional view of the drive assembly 5 provided in the embodiment of this application. The limiting member 54 can be a limiting tube, and the flexible shaft 53 can pass through the middle of the limiting tube. The limiting tube can guide the flexible shaft 53.

[0060] like Figure 2 As shown, the end of the limiting tube away from the drive motor 51 can be set to be parallel to the guide assembly 4. After one end of the flexible shaft 53 passes through the limiting member 54, it can remain parallel to the guide assembly 4, thereby facilitating the movement of the drive assembly 3 by the flexible shaft 53.

[0061] In practical applications, since the flexible shaft 53 is made of soft material, as the driving component 3 moves to different positions of the guide component 4, the flexible shaft 53 can bend accordingly to adapt to the shape of the guide component 4, thus avoiding jamming during the movement of the driving component 3.

[0062] It is understandable that the drive component 5 can also have other configurations, as long as it can drive the drive component 3 to move. For example, the drive component 3 can move linearly along the guide component 4, in which case the drive component 5 can be an electric actuator. In this way, the drive component 5 can also drive the drive component 3 to move along the guide component 4.

[0063] In some embodiments, such as Figure 1 As shown, the vehicle 200 may also include pillar trim 230, which can be connected to the front pillar 220. In this way, the pillar trim 230 can shield the front pillar 220.

[0064] The pillar trim 230 has a receiving cavity 240 on the side near the front pillar 220, and the guide assembly 4 can be disposed within the receiving cavity 240. In this way, the receiving cavity 240 can shield the guide assembly 4, thereby improving the overall aesthetics of the vehicle interior. At the same time, the receiving cavity 240 can also protect the guide assembly 4.

[0065] Understandably, the existing vehicle pillar interior trim 230 near the front pillar 220 usually also has a receiving cavity 240. The guide assembly 4 is set in the receiving cavity 240, which can make full use of the space of the receiving cavity 240. There is no need to make too many modifications to the structure of the front pillar 220, which has little impact on the interior appearance of the vehicle and little impact on the user's vision.

[0066] The interior trim 230 of the pillar also has a guide opening 250 that communicates with the receiving cavity 240, and the drive component 3 passes through the guide opening 250 and is slidably connected to the guide component 4. In this way, the guide opening 250 can avoid the drive component 3, so that the drive component 3 can be slidably connected to the guide component 4.

[0067] In some embodiments, such as Figure 1 As shown, the guide opening 250 is located on the side of the pillar trim 230 near the windshield 210. In this way, the portion of the pillar trim 230 near the interior of the vehicle cabin can be a flat surface, ensuring the appearance of the vehicle interior.

[0068] Understandably, in practical applications, a black border can be provided on the windshield 210 to cover the guide opening 250. In this way, the placement of the guide assembly 4 will not affect the appearance of the vehicle from the outside.

[0069] In some embodiments, such as Figure 4 As shown, Figure 4 This is one of the partial structural schematic diagrams of the sunshade device 100 provided in an embodiment of this application. The fixing member 1 may include a mounting base 11 and a winding shaft 12. The winding shaft 12 is rotatably connected to the mounting base 11. In practical applications, the user can rotate the winding shaft 12 to retract the sunshade 2 when it is in the retracted state. It is understood that the user can also rotate the winding shaft 12 to allow the sunshade 2 to unfold and provide sun protection.

[0070] In practical applications, a coil spring can be configured on the retractor 12. During the unfolding of the sunshade 2, as the sunshade 2 moves, it pulls the retractor 12 to rotate, causing the coil spring to accumulate elastic potential energy. When the sunshade 2 is retracted, the retractor 12 rotates under the influence of the coil spring's elastic potential energy, thus automatically retracting the sunshade 2.

[0071] In practical applications, such as Figure 4 As shown, the limiting member 54 can be connected to the mounting base 11. In this way, the mounting base 11 can provide an installation position for the limiting member 54.

[0072] In some embodiments, such as Figure 2As shown, the guide assembly 4 may include a first guide member 41 and a second guide member 42. Along the extending direction of the fixing member 1, the second guide member 42 is spaced apart from the first guide member 41. One end of the driving assembly 3 is slidably connected to the first guide member 41, and the other end is slidably connected to the second guide member 42. In this way, the first guide member 41 and the second guide member 42 can guide both ends of the driving assembly 3, thereby ensuring smooth movement of the driving assembly 3.

[0073] Specifically, the first guide member 41 and the second guide member 42 can be respectively connected to different front pillars 220 ( Figure 1 ) connection. Thus, along the windshield 210 ( Figure 1 In the width direction, the first guide member 41 and the second guide member 42 can guide the movement of the drive component 3.

[0074] In some embodiments, such as Figure 2 As shown, the driving component 3 may include a first driving member 31 and a second driving member 32. The first driving member 31 is connected to the sunshade 2, one end of the first driving member 31 is slidably connected to the first guide member 41, and the other end extends toward the second guide member 42.

[0075] In practical applications, the first driving member 31 can have a large connection space along the width direction of the sunshade curtain 2, so that the sunshade curtain 2 can be fully connected to the first driving member 31 in the width direction, thereby reducing the wrinkles generated at the end of the sunshade curtain 2 connected to the first driving member 31 during the rising process, and thus improving the flatness of the sunshade curtain 2 after it is unfolded.

[0076] The first driving member 31 is connected to the driving assembly 5. In practical applications, the driving assembly 5 can provide power to the first driving member 31 so that the first driving member 31 can slide along the extension direction of the first guide member 41.

[0077] The second driving member 32 is connected to the sunshade curtain 2. One end of the second driving member 32 is slidably connected to the second guide member 42, and the other end extends towards the first guide member 41. In practical applications, the second driving member 32 can also have a large connection space along the width direction of the sunshade curtain 2, so that the sunshade curtain 2 can be fully connected to the second driving member 32 in the width direction. This reduces the wrinkles that occur at the end of the sunshade curtain 2 connected to the second driving member 32 during the rising process, thereby improving the flatness of the sunshade curtain 2 after it is unfolded.

[0078] Thus, along the front windshield 210 ( Figure 1 In the width direction, both ends of the sunshade 2 can remain relatively flat during the rising process, and the sunshade 2 has a good blocking effect on the windshield after it is unfolded.

[0079] In order to enable the drive component 5 to drive the first drive member 31 and the second drive member 32 to move, in some embodiments, such as Figure 2 As shown, the drive motor 51 and the transmission component 52 can be disposed between the first guide component 41 and the second guide component 42. The flexible shaft 53 may include the first flexible shaft 531 and the second flexible shaft 532. The corresponding limiting component 54 may include the first limiting component and the second limiting component, the end of the first limiting component away from the drive motor 51 may be parallel to the first guide component 41, and the end of the second limiting component away from the drive motor 51 may be parallel to the second guide component 42.

[0080] The first flexible shaft 531 and the second flexible shaft 532 pass through the upper and lower ends of the guide housing, respectively. A transmission gear can be positioned between the first flexible shaft 531 and the second flexible shaft 532, meshing with both. In this way, the transmission gear can simultaneously drive the first flexible shaft 531 and the second flexible shaft 532 to move in opposite directions, so that the first flexible shaft 531, after passing through the first limiting member, can be parallel to the first guide member 41, and the second flexible shaft 532, after passing through the second limiting member, can be parallel to the second guide member 42. Thus, the first flexible shaft 531 and the second flexible shaft 532 can simultaneously drive the first driving member 31 and the second driving member 32 to move in the same direction.

[0081] Since the first driving member 31 and the second driving member 32 move in the same direction, both ends of the sunshade 2 can rise and fall synchronously along the width direction of the sunshade 2. In this way, the sunshade 2 can move evenly along the front windshield 210 (…). Figure 1 The width direction of the sunshade 2 blocks the windshield 210 to ensure the sunshade 2's blocking effect on the windshield 210.

[0082] In some embodiments, such as Figure 2 As shown, along the extending direction of the fixing member 1, the first driving member 31 and the second driving member 32 are spaced apart. In practical applications, the fixing member 1 can extend along the windshield 210 ( Figure 1 The first driving member 31 and the second driving member 32 are positioned in the width direction of the windshield 210. In this way, the first driving member 31 and the second driving member 32 can make way for each other in the width direction of the windshield 210, thereby avoiding some components that are set in the middle of the windshield 210.

[0083] For example, the gap between the first driving member 31 and the second driving member 32 can provide clearance for the rearview mirror base and some control elements installed near the rearview mirror base.

[0084] In some embodiments, such as Figure 2As shown, the sunshade curtain 2 may include a first curtain body 21, a second curtain body 22, and a third curtain body 23. The first curtain body 21 is connected to a first driving member 31, and the third curtain body 23 is connected to a second driving member 32. Along the extending direction of the fixing member 1, the second curtain body 22 is located on one side of the first curtain body 21 and is connected to the first curtain body 21. Along the extending direction of the fixing member 1, the third curtain body 23 is located on the side of the second curtain body 22 away from the first curtain body 21 and is connected to the first curtain body 21.

[0085] In practical applications, the first driving component 31 and the second driving component 32 can drive the first curtain body 21 and the third curtain body 23 to move during the movement, thereby driving the sunshade curtain 2 to move.

[0086] The second curtain 22 is an elastic curtain. Thus, along the windshield 210 ( Figure 1 In the width direction, the second curtain 22 has a certain tensile capacity.

[0087] In practical applications, the width of the windshield 210 typically decreases gradually from bottom to top. Correspondingly, the distance between the two front pillars 220 also gradually decreases from bottom to top. Because the second curtain 22 is elastic, it can be in a stretched state when the sunshade 2 is at the bottom of the windshield 210. As the sunshade 2 rises, the end of the second curtain 22 closest to the windshield 210 gradually returns to its original position. This avoids large-area wrinkles in the middle of the sunshade 2, ensuring a good fit between the sunshade 2 and the windshield 210.

[0088] Understandably, when one end of the sunshade 2 moves to a relatively high position on the windshield 210, the second curtain 22 can return to its original length and create certain folds. At this time, the folds created by the second curtain 22 can be considered as clearance space, thus avoiding obstruction to the rearview mirror. In this way, during the rising process of the sunshade 2, the rearview mirror will not obstruct the sunshade 2, and the sunshade 2 can rise to the top of the windshield 210, thus forming a complete obstruction of the windshield 210, resulting in good heat insulation effect of the sunshade 2.

[0089] Specifically, the fixing member 1 can be positioned on the vehicle body near the bottom of the windshield 210. The distance between the ends of the two front pillars 220 near the fixing member 1 is greater than the distance between the ends of the two front pillars 220 away from the fixing member 1. Thus, the distance between the first guide member 41 and the second guide member 42 connected to the two front pillars 220 can also gradually decrease from bottom to top. Figure 2As shown, when the sunshade curtain 2 descends under the action of the first driving member 31 and the second driving member 32, the distance between the first driving member 31 and the second driving member 32 gradually increases as the first driving member 31 and the second driving member 32 move, and the second curtain body 22 is gradually stretched, thereby avoiding the obstruction of the descent of the sunshade curtain 2.

[0090] When the sunshade curtain 2 rises under the action of the first driving member 31 and the second driving member 32, the distance between the first driving member 31 and the second driving member 32 gradually decreases as the first driving member 31 and the second driving member 32 move. The second curtain body 22 gradually returns to its original size from the stretched state and gradually produces folds to form a clearance space.

[0091] In some embodiments, the first curtain 21, the second curtain 22, and the third curtain 23 may all be non-elastic. The size of the sunshade 2 may be the same as the size of the fixing member 1 along its width direction. This allows the sunshade 2 to wrap smoothly around the fixing member 1 during the rolling-up process.

[0092] Simultaneously, as the sunshade curtain 2 rises under the action of the first driving member 31 and the second driving member 32, the distance between the first driving member 31 and the second driving member 32 gradually decreases with their movement. At this time, the sunshade curtain 2 can also create folds at the second curtain body 22, thereby forming a clearance space.

[0093] In some embodiments, such as Figure 5 As shown, Figure 5 This is a partial cross-sectional view of the sunshade device 100 provided in an embodiment of this application. A first sliding portion 411 is provided on the first guide member 41. The first driving member 31 may include the first sliding member 311 and the first driving member body 312. The first sliding member 311 is slidably connected to the first sliding portion 411, and one end of the first driving member body 312 is connected to the first sliding member 311, while the other end extends towards the second guide member 42 (…). Figure 2 Extending in the direction of ) and the first curtain 21 ( Figure 2 )connect.

[0094] In practical applications, the first sliding part 411 can guide the first sliding member 311, so that the first sliding member 311 and the first driving member body 312 can slide along the first sliding part 411.

[0095] Accordingly, in some embodiments, a second sliding portion may be provided on the second guide member 42. The second driving member 32 may include a second sliding member and a second driving member body. The second sliding member is slidably connected to the second sliding portion, and one end of the second driving member body is connected to the second sliding member, while the other end extends toward the first guide member 41 and is connected to the third curtain 23.

[0096] In this way, the second sliding part can be guided by the second sliding member, so that the second sliding member and the second driving member can slide along the second sliding part.

[0097] In some embodiments, such as Figure 5 As shown, the first sliding part 411 can be a first sliding groove, and the first sliding member 311 is inserted into the first sliding groove. In actual application, as the first sliding member 311 slides along the first sliding groove, the side wall of the first sliding groove can limit the sliding member 311, thereby guiding the sliding of the first sliding member 311.

[0098] It is understood that in some embodiments, the second sliding part can be a second sliding groove, and the second sliding member is inserted into the second sliding groove. In this way, the inner wall of the second sliding groove can also limit the movement of the second sliding member, thereby guiding the sliding of the second sliding member.

[0099] In some embodiments, such as Figure 5 As shown, a first limiting groove 412 may be formed on the side wall of the first sliding groove, and a second limiting groove 314 may be provided on the first sliding member 311. The second limiting groove 314 may be disposed opposite to the first limiting groove 412. The guide assembly 4 may also include a first sliding limiting member 43, a part of which is inserted into the first limiting groove 412 and slidably connected to the first limiting groove 412, and the other part is inserted into the second limiting groove 314.

[0100] In practical applications, as the first sliding member 311 slides along the first sliding groove, the first sliding limit member 43 can slide together with the first sliding member 311.

[0101] Continue to refer to Figure 5 Along a direction perpendicular to the plane where the opening of the first sliding groove is located, the first sliding limiting member 43 abuts against the inner walls of the first limiting groove 412 and the second limiting groove 314. In this way, the first sliding limiting member 43 can restrict the first sliding member 311, preventing the first sliding member 311 from falling out of the first sliding groove from the opening of the first sliding groove, thereby ensuring that the first sliding member 311 can slide stably along the first sliding groove.

[0102] In some embodiments, such as Figure 6 As shown, the first sliding limit member 43 can be spherical, and the second limiting groove 314 can be a spherical groove. In this way, as the first sliding limit member 43 slides with the first sliding member 311, the first sliding limit member 43 can roll, thereby converting sliding friction into rolling friction and reducing the resistance generated by the first sliding limit member 43.

[0103] It is understood that, in some embodiments, a third limiting groove may be formed on the side wall of the second sliding groove, and a fourth limiting groove may be provided on the second sliding member. The fourth limiting groove may be disposed opposite to the third limiting groove. The guide assembly 4 may also include a second sliding limiting member, one part of which is inserted into the third limiting groove and slidably connected to the third limiting groove, and the other part is inserted into the fourth limiting groove.

[0104] In practical applications, as the second sliding member slides along the second sliding groove, the second sliding limit member can slide together with the second sliding member.

[0105] Along a direction perpendicular to the plane where the second sliding groove opening is located, the second sliding limiting member abuts against the inner walls of the third and fourth limiting grooves. In this way, the second sliding limiting member can restrict the second sliding member, preventing the second sliding member from falling out of the second sliding groove opening, thereby ensuring that the second sliding member can slide stably along the second sliding groove.

[0106] Understandably, the second sliding limit member can also be spherical. Correspondingly, the fourth limiting groove can also be a spherical groove. In this way, as the second sliding limit member slides with the second sliding member, the second sliding limit member can also roll, thereby converting sliding friction into rolling friction and reducing the resistance generated by the second sliding limit member.

[0107] In some embodiments, such as Figure 5 and Figure 4 As shown, a first transmission groove 413 can be formed on the bottom wall of the first sliding groove. One end of the first flexible shaft 531 connected to the first driving member 31 can pass through the first transmission groove 413 and be slidably connected to the first transmission groove 413.

[0108] In practical applications, the first transmission groove 413 can limit the first flexible shaft 531, preventing unnecessary bending or deflection of the first flexible shaft 531 during transmission, thereby ensuring that the first flexible shaft 531 can stably drive the first driving member 31 to move along the extension direction of the first guide member 41.

[0109] Specifically, the first transmission groove 413 can be designed according to the shape of the first flexible shaft 531, so as to ensure that the side wall of the first transmission groove 413 can wrap around the outside of the first flexible shaft 531, thereby limiting the first flexible shaft 531.

[0110] In some embodiments, such as Figure 5 and Figure 4As shown, a first connecting portion 313 can be formed on the first sliding member 311. The first connecting portion 313 is inserted into the first transmission groove 413 and slidably connected with the first transmission groove 413. The end of the first flexible shaft 531 can be connected to the end face of the first connecting portion 313. In this way, as the first flexible shaft 531 moves along the first transmission groove 413, it can push the first connecting portion 313 to move, thereby driving the first sliding member 311 to move.

[0111] In some embodiments, a second transmission groove may be formed on the bottom wall of the second sliding groove. One end of the second flexible shaft 532 connected to the second driving member 32 may pass through the second transmission groove and be slidably connected to the second transmission groove.

[0112] In this way, the second transmission groove can also limit the second flexible shaft 532, preventing the second flexible shaft 532 from bending or deflecting unnecessarily during transmission, thereby ensuring that the second flexible shaft 532 can stably drive the second driving member 32 to move along the extension direction of the second guide member 42.

[0113] Specifically, the second transmission groove can also be designed according to the shape of the second flexible shaft 532, so as to ensure that the side wall of the second transmission groove can wrap around the outside of the second flexible shaft 532, thereby limiting the second flexible shaft 532.

[0114] In some embodiments, a second connecting portion may also be formed on the second sliding member, which is inserted into and slidably connected to the second transmission groove. The end of the second flexible shaft 532 may be connected to the end face of the second connecting portion. In this way, the second flexible shaft 532 can push the second connecting portion to move as it moves along the second transmission groove, thereby driving the second sliding member to move.

[0115] It is understood that the sunshade device 100 provided in this application embodiment can also be used to block the vehicle door glass or rear windshield. The sunshade device 100 only needs to be set at a position corresponding to the vehicle door glass or rear windshield so that the sunshade curtain 2 can block the vehicle door glass or rear windshield after it is unfolded.

[0116] For example, the first guide member 41 and the second guide member 42 can be respectively attached to the B-pillar and C-pillar located on the same side of the vehicle. In this way, as the first drive member 31 and the second drive member 32 move along the first guide member 41 and the second guide member 42, they can drive the sunshade 2 to unfold so that the sunshade 2 can block the vehicle door glass.

[0117] Alternatively, the first guide member 41 and the second guide member 42 can be positioned opposite each other on the two C-pillars of the vehicle. In this way, as the first drive member 31 and the second drive member 32 move along the first guide member 41 and the second guide member 42, they can drive the sunshade 2 to unfold, so that the sunshade 2 can cover the rear windshield.

[0118] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
