Summary of the invention

[0005] One of the purposes of the present invention is to provide a sunshade device to solve the problem that the existing sunshade curtain is inconvenient to use. Another purpose of the present invention is to provide a vehicle.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] On the one hand, an embodiment of the present application provides a sunshade device, including a fixing member, a sunshade curtain, a driving assembly, a guide assembly, and a driving assembly. One end of the sunshade curtain is connected to the fixing member. The driving assembly is connected to the other end of the sunshade curtain. Along the extension direction of the guide assembly, the driving assembly is slidably connected to the guide assembly. The driving assembly is connected to the driving assembly, and is used to drive the driving assembly to slide along the extension direction of the guide assembly.

[0008] According to the above technical means, in the process of actual application, the fixing part can be located at one end of the front windshield and connected to the front pillar, and the guide assembly can be arranged parallel to the front windshield and extend in the direction away from the fixing part. In this way, the driving assembly can be driven by the driving assembly from the end of the guide assembly close to the fixing part to the end of the guide assembly away from the fixing part, thereby moving from one end of the front windshield to the other end of the front windshield. With the movement of the driving assembly, the other end of the sunshade can be synchronously moved from one end of the front windshield to the other end, and the sunshade can be converted to an unfolded state. After the sunshade is unfolded, the two ends are respectively located at the opposite ends of the front windshield, so that the front windshield can be shielded. The driving assembly can be driven by the driving assembly from the end of the guide assembly away from the fixing part to the end of the guide assembly close to the fixing part, thereby driving the end of the sunshade connected to the driving assembly to move in the direction close to the fixing part to retract the sunshade. Users do not need to manually open the sunshade. The sunshade device can automatically unfold the sunshade to block the sunlight from the external environment, or automatically retract the sunshade to prevent the sunshade from affecting the user's vision, making it easier for consumers to use.

[0009] In a possible implementation, the guide assembly includes a first guide member and a second guide member. Along the extension direction of the fixing member, the second guide member is arranged relative to the first guide member and spaced apart. 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 technical means, the first guide member and the second guide member can guide both ends of the driving component, thereby ensuring the smooth movement of the driving component.

[0011] In a possible embodiment, the driving assembly includes a first driving member and a second driving member. The first driving member is connected to the sunshade and to the driving assembly. One end of the first driving member is slidably connected to the first guide member, and the other end extends in a direction close to the second guide member. The second driving member is connected to the sunshade and to the driving assembly. One end of the second driving member is slidably connected to the second guide member, and the other end extends in a direction close to the first guide member. Along the extension direction of the fixing member, the first driving member and the second driving member are spaced apart.

[0012] According to the above technical means, along the width direction of the sunshade, the first driving member can have a larger connection space, so that the sunshade can be fully connected to the first driving member in the width direction, thereby reducing the wrinkles generated at the end of the sunshade connected to the first driving member during the rising process, thereby improving the flatness of the sunshade after unfolding. Along the width direction of the sunshade, the second driving member can also have a larger connection space, so that the sunshade can be fully connected to the second driving member in the width direction, thereby reducing the wrinkles generated at the end of the sunshade connected to the second driving member during the rising process, thereby improving the flatness of the sunshade after unfolding. The first driving member and the second driving member can make way in the width direction of the front windshield, thereby avoiding some components arranged in the middle of the front windshield.

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

[0014] According to the above technical means, the width of the front windshield is usually gradually reduced from the bottom to the top. Correspondingly, the distance between the two front pillars is also gradually reduced from the bottom to the top. Since the second curtain body is elastic, when the sunshade is located at the bottom of the front windshield, the second curtain body can be in a stretched state. As the sunshade rises, the end of the second curtain body close to the front windshield gradually returns to its original position. In this way, large wrinkles in the middle of the sunshade can be avoided, and the fitting effect of the sunshade and the front windshield can be ensured.

[0015] In a possible embodiment, a first sliding portion is provided on the first guide member, and a second sliding portion is provided on the second guide member. The 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 in a direction close to the second guide member and is connected to the first curtain body. 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 in a direction close to the first guide member and is connected to the third curtain body.

[0016] According to the above technical means, the first sliding part can guide the first sliding member, so that the first sliding member and the first driving member body can slide along the first sliding part. The second sliding part can guide the second sliding member, so that the second sliding member and the second driving member can slide along the second sliding part.

[0017] In a 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, when the first sliding member slides along the first sliding groove, the side wall of the first sliding groove can limit the first sliding member, thereby guiding the sliding of the first sliding member. The inner wall of the second sliding groove can also limit the second sliding member, thereby guiding the sliding of the second sliding member.

[0019] In a possible embodiment, a first limiting groove is provided on the side wall of the first sliding groove, a second limiting groove is provided on the first sliding member, and the second limiting groove is arranged 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 is slidably connected to the first limiting groove, and the other portion is inserted into the second limiting groove. Along a direction perpendicular to the plane where the notch of the first sliding groove is located, the first sliding limiting member abuts against the inner walls of the first limiting groove and the second limiting groove.

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

[0021] On the other hand, the present application also provides a vehicle, comprising the above-mentioned sunshade device.

[0022] Since the vehicle provided in the embodiment of the present application includes the sunshade device proposed in the first aspect, it can solve the same technical problems as the above-mentioned sunshade device and achieve the same technical effects, which will not be repeated here.

[0023] In a possible embodiment, the vehicle further includes a vehicle body, a front windshield, and two front pillars. The front windshield is connected to the vehicle body. The two front pillars are connected to the vehicle body and are arranged at opposite ends of the front windshield with a relative spacing. The fixing member extends along the spacing direction of the two front pillars and is connected to the vehicle body. The guide assembly is connected to the front pillars, and the guide assembly extends along the extension direction of the front pillars.

[0024] According to the above technical means, the guide assembly can be designed according to the curvature of the front windshield, so that the sunshade can be well fitted with the front windshield. In this way, the sunshade has a better shielding effect on the front windshield, and the sunshade fits the front windshield better after being unfolded, and its overall shape is more beautiful.

[0025] In a possible implementation, the vehicle further includes a pillar interior part. The pillar interior part is connected to the front pillar, a receiving cavity is provided on a side of the pillar interior part close to the front pillar, and the guide assembly is provided in the receiving cavity. A guide opening communicating with the receiving cavity is provided on the pillar interior part, and the driving assembly is provided through the guide opening and slidably connected with the guide assembly.

[0026] According to the above technical means, the accommodating cavity can shield the guide assembly, thereby improving the overall aesthetics of the vehicle interior. At the same time, the accommodating cavity can also protect the guide assembly. The guide opening can avoid the driving assembly, so that the driving assembly can be slidably connected with the guide assembly.

[0027] In a possible implementation, the guide opening is located on a side of the pillar interior component close to the front windshield.

[0028] According to the above technical means, the portion of the pillar interior trim close to the interior of the vehicle can be a flat surface, which can ensure the appearance effect of the interior of the vehicle.

[0029] In a possible implementation manner, the distance between the two front columns at one end close to the fixing member is greater than the distance between the two front columns at one end away from the fixing member.

[0030] According to the above 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 front windshield, so that the sunshade can cover the front windshield.

DETAILED DESCRIPTION

[0040] In order to enable ordinary persons in the art to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0041] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

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

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

[0044] Continue to refer to Figure 1The vehicle 200 may further include a front pillar 220. It is understood that the number of the front pillars 220 may be two, and the two front pillars 220 may be connected to the vehicle body and disposed at opposite ends of the front windshield 210. Specifically, the two front pillars 220 may be disposed at opposite ends of the front windshield 210 along the width direction of the front windshield 210.

[0045] In actual application, the front pillar 220 can improve the overall rigidity of the vehicle 200, thereby improving the safety of passengers riding in the vehicle 200. In addition, along the width direction of the vehicle 200, the front pillar 220 can support both ends of the front windshield 210, thereby improving the stability of the front windshield 210.

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

[0047] Next, the sunshade device 100 provided in the embodiment of the present application is further introduced. Figure 2 As shown, Figure 2 The schematic diagram of the structure of the sunshade device 100 provided in the embodiment of the present application is as follows. 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 driving component 3, a guide component 4, and a driving component 5. The driving component 3 is connected to the other end of the sunshade curtain 2. Along the extension direction of the guide component 4, the driving component 3 is slidably connected to the guide component 4. The driving component 5 is connected to the driving component 3, and is used to drive the driving component 3 to slide along the extension direction of the guide component 4.

[0049] In actual application, the fixing member 1 may be located on the front windshield 210 ( Figure 1 ) and the front column 220( Figure 1 ), the guide assembly 4 can be arranged parallel to the front windshield 210 and extend in a direction away from the fixing member 1. In this way, the driving assembly 3 can be driven by the driving assembly 5 to move from one end of the guide assembly 4 close to the fixing member 1 to the end of the guide assembly 4 away from the fixing member 1, thereby moving from one end of the front windshield 210 to the other end of the front windshield 210.

[0050] It is understandable that, with the movement of the driving assembly 3, the other end of the sunshade 2 can be synchronously moved from one end of the front windshield 210 to the other end, and the sunshade 2 can be converted into an unfolded state. After the sunshade 2 is unfolded, the two ends are respectively located at the opposite ends of the front windshield 210, so that the front windshield 210 can be shielded.

[0051] Driven by the driving assembly 5, the driving assembly 3 can move from one end of the guide assembly 4 away from the fixing member 1 to the end of the guide assembly 4 close to the fixing member 1, thereby driving the end of the sunshade 2 connected to the driving assembly 3 to move toward the direction close to the fixing member 1 to retract the sunshade 2.

[0052] In this way, the user does not need to manually open the sunshade 2. The sunshade device 100 can automatically unfold the sunshade 2 so that the sunshade 2 can block the sunlight from the external environment, or automatically retract the sunshade 2 to prevent the sunshade 2 from affecting the user's line of sight, making it easier for the user to use.

[0053] Specifically, Figure 1 and Figure 2 As shown, the fixing member 1 can extend along the spacing direction of the two front pillars 220 and be connected to the vehicle body. The guide assembly 4 can be connected to the front pillars 220 and extend along the extension direction of the front pillars 220. In this way, the sunshade 2 can form a better shielding effect on the front windshield 210 after being unfolded.

[0054] In actual application, the guide assembly 4 can be designed according to the curvature of the front windshield 210 so that the sunshade 2 can be well fitted with the front windshield 210. In this way, the sunshade 2 has a better shielding effect on the front windshield 210, and the sunshade 2 fits the front windshield 210 better after being unfolded, and its overall shape is more beautiful.

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

[0056] In actual application, the limiter 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 flexible shaft 53 to drive the driving component 3 to move.

[0057] For example, Figure 2 As shown, the transmission member 52 may include a limit housing and a transmission gear, and the transmission gear is connected to the output end of the driving motor 51. The flexible shaft 53 is inserted through the limit housing.

[0058] The flexible shaft 53 can be a bendable transmission rod, and the surface of the flexible shaft 53 can be provided with a transmission tooth groove, and the transmission tooth groove can mesh with a transmission gear. In this way, the transmission gear can drive the flexible shaft 53 to move during the rotation driven by the driving motor 51.

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

[0060] like Figure 2 As shown, the end of the stopper tube away from the driving motor 51 can be set to be parallel to the guide assembly 4. After passing through the stopper 54, one end of the flexible shaft 53 can remain parallel to the guide assembly 4, so that the flexible shaft 53 can drive the driving assembly 3 to move.

[0061] In actual application, since the soft shaft 53 is made of soft material, when the soft shaft 53 drives the driving component 3 to move, as the driving component 3 moves to different positions of the guide component 4, the soft shaft 53 can bend accordingly to adapt to the shape of the guide component 4, thereby avoiding the driving component 3 from getting stuck during the movement.

[0062] It is understandable that the driving assembly 5 can also have other configuration forms, as long as the driving assembly 5 can drive the driving assembly 3 to move. Exemplarily, the driving assembly 3 can move linearly along the guide assembly 4, and the driving assembly 5 can be an electric push rod. In this way, the driving assembly 5 can also drive the driving assembly 3 to move along the guide assembly 4.

[0063] In some embodiments, Figure 1 As shown, the vehicle 200 may further include a pillar interior decoration 230, and the pillar interior decoration 230 may be connected to the front pillar 220. In this way, the pillar interior decoration 230 may shield the front pillar 220.

[0064] The pillar interior part 230 is provided with a receiving cavity 240 on one side close to the front pillar 220, and the guide assembly 4 can be arranged in the receiving cavity 240. In this way, the receiving cavity 240 can shield the guide assembly 4, thereby improving the overall aesthetics of the interior of the vehicle. At the same time, the receiving cavity 240 can also protect the guide assembly 4.

[0065] It is understandable that the pillar interior trim 230 of the existing vehicle usually also has a accommodating cavity 240 near the front pillar 220. The guide assembly 4 is arranged in the accommodating cavity 240, which can fully utilize the space of the accommodating cavity 240 without making too many improvements to the structure of the front pillar 220, has little impact on the interior appearance of the vehicle, and has little impact on the user's field of vision.

[0066] The pillar interior part 230 is also provided with a guide opening 250 communicating with the accommodating cavity 240, and the driving component 3 is passed through the guide opening 250 and slidably connected with the guide component 4. In this way, the guide opening 250 can avoid the driving component 3, so that the driving component 3 can be slidably connected with the guide component 4.

[0067] In some embodiments, Figure 1 As shown, the guide opening 250 is located on a side of the pillar interior decoration 230 close to the front windshield 210. In this way, the portion of the pillar interior decoration 230 close to the interior of the vehicle cabin can be a flat surface, which can ensure the appearance of the interior of the vehicle.

[0068] It is understandable that, in actual application, a black border may be provided on the front windshield 210, and the black border may shield the guide opening 250. In this way, when viewed from the outside of the vehicle, the provision of the guide assembly 4 will not affect the appearance of the vehicle.

[0069] In some embodiments, Figure 4 As shown, Figure 4 One of the partial structural schematic diagrams of the sunshade device 100 provided in the embodiment of the present application, the fixing member 1 may include a mounting seat 11 and a reel 12. The reel 12 is rotatably connected to the mounting seat 11. In actual application, the user can rotate the reel 12 to retract the sunshade 2 when the sunshade 2 is in the retracted state. It is understandable that the user can also rotate the reel 12 to cause the sunshade 2 to scatter from it, so that the sunshade 2 can be unfolded to shade the sun.

[0070] In actual application, a coil spring may be arranged on the reel shaft 12. When the sunshade 2 is unfolded, as the sunshade 2 moves, the sunshade 2 can pull the reel shaft 12 to rotate, and the coil spring can accumulate elastic potential energy. When the sunshade 2 is retracted, the reel shaft 12 can rotate driven by the elastic potential energy of the coil spring, so that the sunshade 2 is automatically retracted.

[0071] In the actual application process, Figure 4 As shown, the limiting member 54 can be connected to the mounting seat 11. In this way, the mounting seat 11 can provide a mounting position for the limiting member 54.

[0072] In some embodiments, Figure 2As shown, the guide assembly 4 may include a first guide member 41 and a second guide member 42. Along the extension direction of the fixing member 1, the second guide member 42 is arranged relative to 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 form guides for 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 ) is connected. In this way, along the front windshield 210 ( Figure 1 ), the first guide member 41 and the second guide member 42 can guide the movement of the driving component 3.

[0074] In some embodiments, Figure 2 As shown, the driving assembly 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 direction close to the second guide member 42.

[0075] During actual application, a larger connection space can be provided on the first driving member 31 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 wrinkles generated at the end of the sunshade curtain 2 connected to the first driving member 31 during the rising process, thereby 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 actual application, the driving assembly 5 can provide power to the first driving member 31 so that the first driving member 31 can slide along the extending 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 in a direction close to the first guide member 41. In actual application, along the width direction of the sunshade curtain 2, the second driving member 32 can also have a larger connection space, so that the sunshade curtain 2 can be fully connected to the second driving member 32 in the width direction, thereby reducing the wrinkles generated 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 curtain 2 can maintain a relatively flat state during the rising process, and the sunshade curtain 2 has a better shielding effect on the front windshield after being unfolded.

[0079] In order to realize that the driving assembly 5 can drive the first driving member 31 and the second driving member 32 to move, in some embodiments, such as Figure 2 As shown, the driving motor 51 and the transmission member 52 may be arranged between the first guide member 41 and the second guide member 42. The flexible shaft 53 may include a first flexible shaft 531 and a second flexible shaft 532. The corresponding stopper 54 may include a first stopper and a second stopper, and an end of the first stopper away from the driving motor 51 may be parallel to the first guide member 41, and an end of the second stopper away from the driving motor 51 may be parallel to the second guide member 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, and the transmission gear can be arranged between the first flexible shaft 531 and the second flexible shaft 532, and mesh with the first flexible shaft 531 and the second flexible shaft 532, respectively. In this way, the movable 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 can be parallel to the first guide member 41 after passing through the first stopper, and the second flexible shaft 532 can be parallel to the second guide member 42 after passing through the second stopper. In this way, 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, the two 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 be evenly moved along the front windshield 210 ( Figure 1 ) forms a shielding effect on the front windshield 210 in the width direction to ensure the shielding effect of the sunshade 2 on the front windshield 210.

[0082] In some embodiments, Figure 2 As shown, along the extension direction of the fixing member 1, the first driving member 31 and the second driving member 32 are arranged at intervals. In the actual application process, the fixing member 1 can be arranged along the front windshield 210 ( Figure 1 In this way, the first driving member 31 and the second driving member 32 can make way in the width direction of the front windshield 210, thereby avoiding some components arranged in the middle of the front windshield 210.

[0083] Exemplarily, the interval between the first driving member 31 and the second driving member 32 can provide a clearance for the rearview mirror base and some control components installed near the rearview mirror base.

[0084] In some embodiments, 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 the first driving member 31, and the third curtain body 23 is connected to the second driving member 32. Along the extension 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 extension 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 actual application, the first driving member 31 and the second driving member 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 body 22 is an elastic curtain body. Figure 1 ) in the width direction, the second curtain body 22 has a certain stretching ability.

[0087] In actual application, the width of the front windshield 210 is usually gradually reduced from the bottom to the top. Correspondingly, the distance between the two front pillars 220 is also gradually reduced from the bottom to the top. Since the second curtain body 22 is elastic, when the sunshade 2 is located at the bottom of the front windshield 210, the second curtain body 22 can be in a stretched state. As the sunshade 2 rises, the end of the second curtain body 22 close to the front windshield 210 gradually returns to its original position. In this way, it is possible to avoid large wrinkles in the middle of the sunshade 2, and ensure the fitting effect of the sunshade 2 and the front windshield 210.

[0088] It is understandable that when one end of the sunshade 2 moves to a position relatively above the front windshield 210, the second curtain body 22 can restore its original length and generate certain wrinkles. At this time, the wrinkles generated by the second curtain body 22 can be regarded as an avoidance space, thereby forming an avoidance space for the rearview mirror. In this way, during the rising process of the sunshade 2, the rearview mirror will not block the sunshade 2, and the sunshade 2 can rise to the top of the front windshield 210, thereby forming a complete blockage for the front windshield 210, and the sunshade 2 has a good heat insulation effect.

[0089] Specifically, the fixing member 1 can be disposed at a position of the vehicle body close to the bottom of the front windshield 210. The distance between the two front pillars 220 near the fixing member 1 is greater than the distance between the two front pillars 220 away from the fixing member 1. In this way, the distance between the first guide member 41 and the second guide member 42 connected to the two front pillars 220 can also be gradually reduced from bottom to top. Figure 2As shown, when the sunshade curtain 2 is driven by the first driving member 31 and the second driving member 32 to descend, along with the movement 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, and the second curtain body 22 is gradually stretched, thereby avoiding obstruction in the descent of the sunshade curtain 2.

[0090] When the sunshade curtain 2 rises driven by the first driving member 31 and the second driving member 32, with the movement 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, the second curtain body 22 gradually recovers to its original size from the stretched state, and gradually generates wrinkles to form an avoidance space.

[0091] In other embodiments, the first curtain body 21, the second curtain body 22 and the third curtain body 23 may not be elastic. Along the width direction of the fixing member 1, the size of the sunshade curtain 2 may be consistent with the size of the fixing member 1. In this way, the sunshade curtain 2 can be smoothly wound around the fixing member 1 during the rolling process.

[0092] At the same time, when the sunshade curtain 2 is raised driven by 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 the movement of the first driving member 31 and the second driving member 32. At this time, the sunshade curtain 2 can also generate folds at the second curtain body 22, thereby forming an escape space.

[0093] In some embodiments, Figure 5 As shown, Figure 5 The partial cross-sectional view of the sunshade device 100 provided in the embodiment of the present application, the first guide member 41 is provided with a first sliding portion 411. The first driving member 31 may include a first sliding member 311 and a first driving member body 312. The first sliding member 311 is slidably connected to the first sliding portion 411, one end of the first driving member body 312 is connected to the first sliding member 311, and the other end is close to the second guide member 42 ( Figure 2 ) direction, and the first curtain body 21 ( Figure 2 )connect.

[0094] In actual application, the first sliding portion 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 portion 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, one end of the second driving member body is connected to the second sliding member, and the other end extends toward the direction close to the first guide member 41 and is connected to the third curtain body 23.

[0096] In this way, the second sliding portion can form a guide for the second sliding member, so that the second sliding member and the second driving member can slide along the second sliding portion.

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

[0098] It is understandable that, in some embodiments, the second sliding portion 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 second sliding member, thereby guiding the sliding of the second sliding member.

[0099] In some embodiments, Figure 5 As shown, a first limiting groove 412 may be provided 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 arranged opposite to the first limiting groove 412. The guide assembly 4 may further include a first sliding limiting member 43, a part of the first sliding limiting member 43 is inserted into the first limiting groove 412, and is slidably connected to the first limiting groove 412, and the other part is inserted into the second limiting groove 314.

[0100] In actual application, when the first sliding member 311 slides along the first sliding groove, the first sliding stopper 43 can slide together with the first sliding member 311 .

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

[0102] In some embodiments, Figure 6 As shown, the first sliding stopper 43 may be spherical, and the second stopper groove 314 may be a spherical groove. In this way, when the first sliding stopper 43 slides with the first sliding member 311, the first sliding stopper 43 may roll, thereby converting the sliding friction into rolling friction, so as to reduce the resistance generated by the first sliding stopper 43.

[0103] It is understandable that, in some embodiments, a third limiting groove may be provided 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 arranged opposite to the third limiting groove. The guide assembly 4 may further include a second sliding limiting member, a 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 actual application, when the second sliding member slides along the second sliding groove, the second sliding limiter can slide together with the second sliding member.

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

[0106] It is understandable that the second sliding stopper may also be spherical. Accordingly, the fourth stopper groove may also be a spherical groove. In this way, when the second sliding stopper slides with the second sliding member, the second sliding stopper may also roll, thereby converting the sliding friction into rolling friction to reduce the resistance generated by the second sliding stopper.

[0107] In some embodiments, Figure 5 and Figure 4 As shown, the bottom wall of the first sliding groove may be provided with a first transmission groove 413. One end of the first flexible shaft 531 connected to the first driving member 31 may be inserted into the first transmission groove 413 and slidably connected to the first transmission groove 413.

[0108] In actual application, the first transmission groove 413 can limit the first flexible shaft 531 to prevent 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 to ensure that the side wall of the first transmission groove 413 can be wrapped around the outside of the first flexible shaft 531 , thereby limiting the first flexible shaft 531 .

[0110] In some embodiments, Figure 5 and Figure 4As shown, the first connecting portion 313 may be formed on the first sliding member 311, and the first connecting portion 313 is inserted into the first transmission groove 413 and is slidably connected to the first transmission groove 413. The end of the first flexible shaft 531 may be connected to the end surface of the first connecting portion 313. In this way, the first flexible shaft 531 may push the first connecting portion 313 to move during the movement along the first transmission groove 413, thereby driving the first sliding member 311 to move.

[0111] In some embodiments, a second transmission groove may be provided 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 be inserted into the second transmission groove and slidably connected to the second transmission groove.

[0112] In this way, the second transmission groove can also limit the second flexible shaft 532 to prevent the second flexible shaft 532 from unnecessary bending or deflection 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 to ensure that the side wall of the second transmission groove can be wrapped 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, and the second connecting portion is inserted into the second transmission groove and is slidably connected to the second transmission groove. The end of the second flexible shaft 532 may be connected to the end surface of the second connecting portion. In this way, the second flexible shaft 532 may push the second connecting portion to move during the movement along the second transmission groove, thereby driving the second sliding member to move.

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

[0116] For example, the first guide member 41 and the second guide member 42 may be located on the B-pillar and the C-pillar on the same side of the vehicle, respectively. In this way, the first driving member 31 and the second driving member 32 may drive the sunshade 2 to unfold during the movement of the first guide member 41 and the second guide member 42, so that the sunshade 2 may cover the vehicle door glass.

[0117] Alternatively, the first guide member 41 and the second guide member 42 may be disposed on two C-pillars of the vehicle relative to each other. In this way, the first driving member 31 and the second driving member 32 may drive the sunshade 2 to unfold during the movement of the first guide member 41 and the second guide member 42, so that the sunshade 2 may cover the rear windshield.

[0118] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto, and any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
