[0026] The beneficial effects achieved by this utility model are as follows: The sunshade device provided by this utility model has a sunshade curtain that is installed on an external medium via a mounting frame. One support frame has a support rod arranged along the first side edge, connecting to and opening one side of the first sunshade portion. The other support frame has a support rod connected to and opening the other side of the first sunshade portion along the second side edge. The support rods of both support frames are connected to the mounting base via connecting components. The support rods can switch between a first support position and a second support position relative to the mounting base via the connecting components to adjust the tilt angle of the first sunshade portion relative to the external medium surface, thereby adjusting the sunshade angle of the first sunshade portion. A first retaining structure keeps the support rod in the first or second support position, thus maintaining the first sunshade portion at the corresponding sunshade angle. Compared to existing... The previous technology used a telescopic rod arranged at an angle to the sunshade to adjust and position the sunshade angle by extending and shortening it. In this invention, the sunshade angle of the first sunshade part is adjusted and positioned by switching the support rod between a first support position and a second support position relative to the mounting base. The two support rods are arranged and connected along the first and second side edges of the first sunshade part, respectively. The support rods are less likely to interfere with the driver's vision, thus reducing the interference of the sunshade device on the driver's vision, making it safer to use. Moreover, the structure is simple. The entire sunshade device can be installed by detachably connecting the mounting base of the support frame to the external medium, and the entire sunshade device can be disassembled by removing the mounting base of the support frame from the external medium. The installation and disassembly are more convenient and easier to use.

Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0044] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0045] like Figures 1-9As shown in the figure, as an embodiment of the present invention, a sunshade device is provided, including a mounting frame 100 and a sunshade curtain 200. The sunshade curtain 200 includes a first sunshade portion 210 for blocking sunlight, the first sunshade portion 210 having a first side edge 211 and a second side edge 212 arranged along its periphery. The mounting frame 100 is used to mount the sunshade curtain 200 on an external medium such as window glass or window frame, especially for mounting on the windshield of a vehicle or on the frame or dashboard around the windshield. The mounting frame 100 includes two or more support frames, each support frame including a mounting base 110 detachably connected to an external medium and a support rod 130 connected at one end to the mounting base 110 via a connecting assembly 120. The support rod 130 of one support frame is arranged along a first side edge 211 and connects to and opens one side of the first sunshade 210 along the first side edge 211. The support rod 130 of the other support frame is arranged along a second side edge 212 and connects to and opens the other side of the first sunshade 210 along the second side edge 212. The support rod 130 can be switched between a first support position A and a second support position B relative to the mounting base 110 via the connecting assembly 120 to adjust the tilt angle of the first sunshade 210 relative to the external medium surface, thereby adjusting the sunshade angle of the first sunshade 210. When the support rod 130 is in the first support position A, the end of the support rod 130 away from the mounting base 110 is away from the external medium surface. When the support rod 130 is in the second support position B, the end of the support rod 130 away from the mounting base 110 is close to the external medium surface. Furthermore, the connecting assembly 120 includes a first retaining structure 125 capable of holding the support rod 130 in either a first support position A or a second support position B. The first retaining structure 125 holds the support rod 130 in either the first support position A or the second support position B, thereby maintaining the first shading portion 210 at the corresponding shading angle. Compared to the prior art method of adjusting and positioning the shading angle of the sunshade by extending and shortening a telescopic rod arranged at an angle to the sunshade, this embodiment adjusts and positions the shading angle by switching the support rod 130 relative to the mounting base 110 between the first support position A and the second support position B. The shading angle of the first sunshade 210 is positioned, and the two support rods 130 are arranged and connected along the first side edge 211 and the second side edge 212 of the first sunshade 210, respectively. The support rods 130 are less likely to interfere with the driver's line of sight, thereby reducing the interference of the sunshade device with the driver's line of sight, making it safer to use. Moreover, the structure is simple. The entire sunshade device can be installed by simply connecting the mounting base 110 of the support frame to the external medium, and the entire sunshade device can be disassembled by removing the mounting base 110 of the support frame from the external medium. The installation or disassembly is more convenient and easy to use.

[0046] like Figure 1 , Figure 2As shown, in some specific embodiments, when each support rod 130 is in the first support position A, it can open and support the first sunshade 210 at the first sunshade angle. When each support rod 130 is in the second support position B, it can open and support the first sunshade 210 at the second sunshade angle. The shading area of ​​the first sunshade 210 when it is in the first sunshade angle is smaller than the shading area of ​​the first sunshade 210 when it is in the second sunshade angle. Thus, by switching the support rod 130 between the first support position A and the second support position B, the first sunshade 210 can be switched between the first sunshade angle and the second sunshade angle, thereby adjusting the size of the shading area of ​​the first sunshade 210 to adapt to different usage scenarios.

[0047] In some specific embodiments, the connecting component 120 is connected between the lower end of the support rod 130 and the mounting base 110. When the first sunshade 210 is at the first sunshade angle, the height of the end of the support rod 130 away from the mounting base 110 is lower than the height of the end of the support rod 130 away from the mounting base 110 when the first sunshade 210 is at the second sunshade angle. When the first sunshade 210 is at the first sunshade angle, a first visualization area E is formed between the upper surface of the first sunshade 210 and the surface of the external medium for viewing the area above the first sunshade 210. When the sunshade device is installed in the vehicle, the outside of the windshield, the outside of the side windshields, and the rearview mirror can be viewed through the first visualization area E. A second visualization area F is formed below the lower surface of the first sunshade 210 for viewing the area below the first sunshade 210. When the sunshade device is installed in the vehicle, the driver's seat can be viewed through the second visualization area F, making it convenient to use the sunshade device for sun protection while the vehicle is in motion. When the first sunshade 210 is located at the second sunshade angle, the sunshade area is larger, making it convenient to use the sunshade device for sun protection when the vehicle is parked. The first sunshade 210 can block sunlight that penetrates the surface of an external medium. When the sunshade device is installed inside the vehicle, and the first sunshade 210 is at the first sunshade angle, it can block sunlight that penetrates the surface of the windshield, preventing sunlight from penetrating the windshield and shining on the dashboard, front seats, driver's legs, or passenger's legs. This prevents the dashboard from being damaged by sun exposure while the vehicle is in motion, improving vehicle safety and enhancing the coolness of the cabin and front seats while the vehicle is in motion. It also provides sun protection for the lower bodies of the driver and passenger. When the first sunshade 210 is at the second sunshade angle, it can block sunlight that penetrates the surface of the windshield, preventing sunlight from penetrating the windshield and shining into the cabin. This prevents the dashboard from being exposed to sun exposure when the vehicle is parked and enhances the coolness of the cabin while the vehicle is in motion. The dashboard includes a dashboard base, steering wheel, instrument panel, display screen, and other structures.

[0048] like Figure 4As shown, in some specific embodiments, the first side edge 211 and the second side edge 212 are respectively arranged on both sides of the length direction of the first sunshade portion 210. The first sunshade portion 210 can be unfolded into a sunshade state by the support rod 130 connected to the first side edge 211 and the support rod 130 connected to the second side edge 212. The structure is simple and practical. In other embodiments, the first side edge and the second side edge can also be arranged along the adjacent or non-adjacent side of the first sunshade portion 210 and at an angle. The angle is greater than 0° and less than 90°, or greater than 90° and less than 180°. They can also be unfolded into a sunshade state by the support rod 130 connected to the first side edge 211 and the support rod 130 connected to the second side edge 212.

[0049] In some specific embodiments, the sunshade 200 is made of a soft fabric. On the one hand, this prevents the driver from being injured by impacting the sunshade during vehicle operation due to sudden braking or other reasons, thus improving safety when using sunshade while driving. On the other hand, the soft fabric can deform and fold to reduce its space occupation, making it convenient to store the sunshade 200. Furthermore, the deformability of the soft fabric allows the relative distance between the first side edge 211 and the second side edge 212 to be adjusted by selectively installing the mounting base 110 of a support frame connected to the first side edge 211 or the mounting base 110 of a support frame connected to the second side edge 212 on an external medium. This adapts to different width sunshade needs, especially suitable for vehicles with windshields of different widths, making it more flexible and applicable to a wider range of situations. In this embodiment, the sunshade 200 is made of a soft fabric with sun protection function, such as pearl-finish aluminum film fabric, which has good sun protection effect. In other embodiments, other flexible fabrics may also be used.

[0050] like Figure 3 , Figure 4 As shown, in some specific embodiments, the support rod 130 is configured as a telescopic rod assembly. The first side edge 211 and the second side edge 212 can deform and converge as the telescopic rod assembly connected to them shortens, thereby causing the first sunshade part 210 to retract to a stored state. This allows the sunshade curtain 200 to be folded and stored without removing it from the vehicle after the sunshade device is installed on an external medium, such as a vehicle. This reduces the tedious operation of frequently installing or removing the sunshade device and facilitates quick switching between the sunshade state and the stored state. It allows the sunshade curtain 200 to be quickly retracted when the vehicle is driving at night, or quickly unfolded when the vehicle is driving or parked during the day. In this embodiment, the telescopic rod assembly includes multiple sequentially telescopically connected sleeve rods, facilitating extension or shortening, and providing good stability for supporting the first sunshade part 210. In other embodiments, the telescopic rod assembly can also be configured with other structures that can extend and shorten.

[0051] like Figure 4 As shown, in some specific embodiments, one or more clamping members 150 are detachably connected to the support rod 130 to fix the relative position of the first sunshade part 210 and the support rod 130. The clamping members 150 are used to prevent the sunshade curtain 200 from sliding relative to the support rod 130, thereby improving the stability of the support rod 130 in supporting the first sunshade part 210. Furthermore, the clamping members 150 can clamp and fix different positions on the first sunshade part 210 to the support rod 130, thereby adjusting the length, width, or shape of the first sunshade part 210, making the sunshade device more widely applicable.

[0052] In some specific embodiments, the clamping member 150 is provided with a through-hole groove 151 for fitting over the support rod 130. One side of the clamping member 150 is provided with a slot 152 communicating with the through-hole 151. The clamping member 150 can move radially along the support rod 130 via the slot 152 to clamp and fix a portion of the first sunshade 210 between the through-hole 151 and the support rod 130, or move radially along the support rod 130 via the slot 152 to separate the first sunshade 210 from the support rod 130. This method is simple to operate and convenient to use. In this embodiment, the clamping member 150 is made of resin material, possessing a certain degree of elasticity. Under elastic force, it can hold the first sunshade 210 and the support rod 130 tightly, improving the stability of the clamping member 150 in fixing the relative position of the first sunshade 210 and the support rod 130, and its structure is simple. In other embodiments, the clamp 150 can also be configured as a clip structure, which can also be used to fix the relative position of the first sunshade 210 and the support rod 130.

[0053] like Figure 4 As shown, in some specific embodiments, the first side edge 211 and the second side edge 212 form a sleeve structure. The sleeve structure is sleeved on the outside of the support rod 130, further improving the stability of the support rod 130 in supporting the first sunshade 210, and allowing the first sunshade 210 to unfold more smoothly. The first sunshade 210 can be rolled up around the support rod 130 along the sleeve structure to adjust the unfolded length of the first sunshade 210. It can also deform and shrink as the support rod 130 shortens to adjust the unfolded width of the first sunshade 210, thus facilitating the adjustment of the unfolded length and width of the first sunshade 210, adapting to different application scenarios, especially suitable for use in vehicles of different models and specifications, and is highly practical. Furthermore, after the length and width of the first sunshade 210 are adjusted, the clamping member 150 can be used to fix the relative position of the first sunshade 210 and the support rod 130, so that the first sunshade 210 is maintained at the adjusted length and width.

[0054] In some specific embodiments, the two sleeve structures are respectively formed by curling the first side edge 211 and the second side edge 212. The end of the support rod 130 away from the mounting base 110 is detachably connected to the limiting member 140. The side wall of the support rod 130 is provided with a first limiting block 131 arranged on the side of the limiting member 140 near the mounting base 110. The end of the sleeve structure can be clamped between the first limiting block 131 and the limiting member 140, thereby fixing the end of the sleeve structure to the end of the support rod 130 away from the mounting base 110, improving the stability of the support rod 130 in opening the first sunshade 210, and allowing the first sunshade 210 to unfold more smoothly.

[0055] like Figure 6 As shown, in some specific embodiments, the limiting member 140 includes an anti-collision portion 141 for wrapping around the end of the support rod 130 away from the mounting base 110, and a pressing portion 142 protruding from the side of the anti-collision portion 141 near the mounting base 110 toward the mounting base 110. The side wall of the support rod 130 is also provided with a second limiting block 132 protruding outward, and the second limiting block 132 is spaced apart on the side of the first limiting block 131 away from the mounting base 110. A third limiting block 143 is provided inside the anti-collision portion 141. When the limiting member 140 is connected to the support rod 130, the pressing portion 142 and the third limiting block 143 are interference-fitted between the first limiting block 131 and the second limiting block 132, and the end of the sleeve structure can be clamped between the first limiting block 131 and the pressing portion 142. The pressing part 142 is configured with several tapered protrusions, and the cone angle of the tapered protrusions is arranged towards the mounting base 110. Compared with a ring structure, the tapered protrusion design makes the pressing part 142 easier to deform and fit tightly between the third limiting block 143 and the end of the sleeve structure, thus providing more stable fixation for the end of the sleeve structure. Of course, in other embodiments, the pressing part 142 can also be configured as a ring structure or several spherical protrusions, or other structures, which can also be used to fix the end of the sleeve structure. In this embodiment, the limiting member 140 is made of flexible materials such as soft silicone or soft rubber. On the one hand, it is easy to deform and fit more tightly with the support rod 130. On the other hand, it improves the safety of use, for example, it can prevent the driver or co-driver from being injured by hitting the support rod 130 during sudden braking when the vehicle is in motion.

[0056] like Figure 5As shown, in some specific embodiments, the connecting assembly 120 includes a first connector 121 and a second connector 122 rotatably connected to each other along a first axis X. The first connector 121 is connected to one end of the support rod 130 near the mounting base 110. The support rod 130 can rotate between a first support position A and a second support position B as the first connector 121 rotates relative to the second connector 122 around the first axis X, thereby switching between the first support position A and the second support position B. A first retaining structure 125 is arranged between the first connector 121 and the second connector 122, and can retain the support rod 130 in the first support position A or the second support position B by preventing the first connector 121 from rotating relative to the second connector 122 around the first axis X. The operation is simple and convenient. In another embodiment of this utility model, the first connecting member and the second connecting member can also be connected via an insertion positioning structure. The support rod 130 is held at the first support position A by inserting the first connecting member into the second connecting member along the first support position A, and at the second support position B by inserting the first connecting member into the second connecting member along the second support position B. In other embodiments, the first connecting member and the second connecting member can also be connected via other positioning structures such as a snap-fit ​​positioning structure, all of which can hold the support rod 130 at either the first support position A or the second support position B.

[0057] In some specific embodiments, a first connecting member 121 is provided with a first connecting channel 1211 along the first axis X, and a second connecting member 122 is provided with a second connecting channel 1221 along the first axis X. The first connecting member 121 and the second connecting member 122 are rotatably connected within the first connecting channel 1211 and the second connecting channel 1221 by a connecting shaft 127. One end of the connecting shaft 127 is provided with a first limiting plate 128, and the other end is provided with a second limiting plate 129. The movement of the first connecting member 121 and the second connecting member 122 along the first axis X is limited between the first limiting plate 128 and the second limiting plate 129. After the first connector 121 and the second connector 122 are connected, the first retaining structure 125 is interference-fitted between the first connector 121 and the second connector 122 to prevent the first connector 121 from rotating relative to the second connector 122 around the first axis X. This allows the first retaining structure 125 to not only hold the support rod 130 at the first support position A or the second support position B, but also to hold the support rod 130 at any third support position when it rotates around the first axis X between the first support position A and the second support position B. This enables more adjustments to the sunshade angle, adapting to more usage scenarios, and is especially suitable for drivers of different heights to provide sunshade while the vehicle is in motion. In this embodiment, the first retaining structure 125 is made of a soft material, which is easily deformed under stress, improving the tightness of the connection between the first connector 121 and the second connector 122.

[0058] like Figure 7 As shown, in some specific embodiments, the connecting shaft 127 includes a first shaft 1271 and a second shaft 1272 arranged along the first axis X. A first limiting plate 128 is connected to the end of the first shaft 1271 away from the second shaft 1272, and a second limiting plate 129 is connected to the end of the second shaft 1272 away from the first shaft 1271. The end of the first shaft 1271 away from the first limiting plate 128 is threadedly connected to the end of the second shaft 1272 away from the second limiting plate 129. When the first shaft 1271 rotates helically relative to the second shaft 1272, it can drive the first limiting plate 128 and the second limiting plate 129 to move closer to each other along the first axis X, so as to pull the first connecting member 121 and the second connecting member 122 closer to each other along the first axis X until the first retaining structure 125 is interference-fitted between the first connecting member 121 and the second connecting member 122. Furthermore, the threaded connection between shaft 1271 and shaft 21272 allows for adjustment of the preload of the connection between the first connecting member 121 and the second connecting member 122.

[0059] like Figure 4As shown, in some specific embodiments, the connecting assembly 120 further includes a third connector 123, a fourth connector 124, and a second retaining structure 126 disposed between the third connector 123 and the second connector 124. The third connector 123 is connected to the mounting base 110. One end of the second connector 122 extends out of the fourth connector 124, and the other end is rotatably sleeved inside the fourth connector 124. The fourth connector 124 is sleeved outside the third connector 123. When the fourth connector 124 rotates relative to the third connector 123 to lock, the second connector 122 can be fixedly connected to the third connector 123 by the second retaining structure 126 at multiple angles relative to the third connector 123 rotating around the second axis Y. This allows the preset position of the first axis X to be fixed in multiple different positions, enabling the first connector 121 to rotate relative to the second connector 122 in different directions to adjust the shading direction of the first shading part 210, thereby making the application range of the shading device wider.

[0060] In some specific embodiments, the second connector 122 includes a connecting end 20 and a mounting end 10 connected to each other. The connecting end 20 is rotatably connected to the first connector 121 along the first axis X. A first mating surface 11 is formed on the end face of the mounting end 10 away from the connecting end 20, and a first limiting surface 12 is formed on the end face of the mounting end 10 near the connecting end 20. The fourth connector 124 is threadedly connected to the third connector 123 along the second axis Y. The structure is simple, and the installation or disassembly is convenient. The threaded structure also allows for adjustment of the preload of the connection between the fourth connector 124 and the third connector 123. The second axis Y is arranged perpendicular to the first axis X. The fourth connector 124 has a second limiting surface 1241 for engaging with the first limiting surface 12. The second retaining structure 126 is arranged inside the third connector 123 and has a second mating surface 1261 for engaging with the first mating surface 11 on the side near the second connector 122. When the fourth connector 124 is locked by spiral rotation relative to the third connector 123, the second mating surface 1261 can engage with the first mating surface 11 to prevent the second connector 122 from rotating relative to the third connector 123 around the second axis Y. This allows the second retaining structure 126 to keep the first axis X in a preset position, thereby allowing the support rod 130 to rotate relative to the mounting base 110 along a preset shading direction to adjust the shading angle. In this embodiment, the first connector 121 includes a rotating end 30 near the second connector 122. The connecting end 20 includes a connecting portion 1 21 and a connecting portion 22 arranged on both sides of the rotating end 30. A first retaining structure 125 is arranged between the connecting portion 1 21 and one side of the rotating end 30, and between the connecting portion 22 and the other side of the rotating end 30. The connecting portion 1 21 and the connecting portion 22 are respectively provided with a second connecting channel 1221 arranged along the first axis X. The rotating end 30 is provided with a first connecting channel 1211 arranged along the first axis X. Each of the first retaining structures 125 is respectively provided with a second connecting channel 1221 arranged along the first axis X. The third connecting channel 1251 is connected to the first connecting member 121 and the second connecting member 122 via a connecting shaft 127. The first connecting member 121 and the second connecting member 122 are rotatably connected within the first connecting channel 1211, the second connecting channels 1221 and the third connecting channel 1251. After connection, one of the first retaining structures 125 is interference-fitted between the connecting part 1 21 and one side of the rotating end 30, and the other first retaining structure 125 is interference-fitted between the connecting part 2 22 and the other side of the rotating end 30, thereby improving the stability of holding the first connecting member 121 relative to the second connecting member 122 in the first support position A, the second support position B or the third support position.The cross-section of the connecting shaft 127 is set to a non-circular structure, and the second connecting channel 1221 is set to a non-circular structure that matches the connecting shaft 127 to prevent the connecting shaft 127 from rotating relative to the second connecting member 122. The first connecting channel 1211 and the third connecting channel 1251 are set to a circular structure so that the first connecting member 121 and the first retaining structure 125 can rotate relative to the connecting shaft 127.

[0061] In some specific embodiments, the second retaining structure 126 is supported and positioned on the third connector 123. The second retaining structure 126 is made of a soft material, which is easily deformed under stress, thereby improving the tightness of the connection between the second connector 122 and the third connector 123. When the fourth connector 124 is locked relative to the third connector 123 by helical rotation, the second retaining structure 126 can be interference-fitted between the third connector 123 and the first mating surface 11 to prevent the second connector 122 from rotating relative to the third connector 123 around the second axis Y.

[0062] like Figure 8 As shown, in some specific embodiments, the mounting base 110 is configured as a suction cup for adsorbing onto the surface of an external medium, and the fourth connector 124 is configured as a suction cup cover. A pressure ring 1242 is formed on the suction cup cover near the end of the suction cup for pressing the suction cup onto the surface of the external medium, arranged around the third connector 123. When the suction cup cover is rotated relative to the third connector 123 to lock, it can move the third connector 123 away from the surface of the external medium, causing a portion of the suction cup in the middle of the pressure ring 1242 to deform and bulge along with the third connector 123 away from the surface of the external medium, forming a vacuum adsorption cavity, thereby firmly adsorbing the mounting base 110 onto the surface of the external medium. In this embodiment, by rotating the fourth connector 124 relative to the third connector 123, the support rod 130 can be installed and positioned relative to the mounting base 110 in the preset shading direction, while the mounting base 110 is firmly attached to the surface of the external medium. This gives the fourth connector 124 the dual function of driving the second connector 122 and the third connector 123 to be fixedly connected, and driving the mounting base 110 to be firmly attached to the surface of the external medium.

[0063] like Figure 8 , Figure 9As shown, in some specific embodiments, the third connector 123 includes a connecting platform 1231 connected to the back of the mounting base 110 and a connecting frame 1232 extending from the connecting platform 1231 in a direction away from the mounting base 110. The second retaining structure 126 is disposed between the connecting platform 1231 and the first mating surface 11, and can provide a supporting force for the second retaining structure 126 through the connecting platform 1231 to support the second connector 122. The second connector 122 can rotate spirally relative to the connecting frame 1232 around the second axis Y to adjust the angle. The fourth connector 124 can be threaded onto the outside of the connecting frame 1232 and rotatably fastened onto the outside of the second connector 122. When the fourth connector 124 is locked by spiral rotation relative to the connecting frame 1232, it can drive the third connector 123 to move away from the external medium surface, and drive the second retaining structure 126 to move away from the external medium surface with the third connector 123. The second retaining structure 126 is then interference-fitted between the connecting table 1231 and the first mating surface 11 to prevent the second connector 122 from rotating relative to the second retaining structure 126 around the second axis Y. The second retaining structure 126 and the mounting base 110 are integrally molded from soft rubber. At least one flow channel 1233 for filling soft rubber is provided through the connecting platform 1231. The soft rubber filled in the flow channel 1233 forms a connecting post 160 connecting the second retaining structure 126 and the mounting base 110, thereby limiting the second retaining structure 126 and the mounting base 110 to the two sides of the connecting platform 1231, so as to prevent the second retaining structure 126 or the mounting base 110 from moving relative to the connecting platform 1231 along the second axis Y, and limiting the connecting post 160 in the flow channel 1233, so as to prevent the second retaining structure 126 or the mounting base 110 from moving radially or rotating around the second axis Y relative to the connecting platform 1231. In specific processing, the second retaining structure 126, the mounting base 110 and the connecting post 160 can be directly formed by injecting glue into the third connector 123, so that the second retaining structure 126, the mounting base 110 and the connecting post 160 form an integral structure. A stepped groove 1234 for filling with soft adhesive is formed on the side of the connecting platform 1231 away from the mounting base 110 and recessed towards the mounting base 110. The soft adhesive filled in the stepped groove 1234 forms part of the structure of the second retaining structure 126 and is used to strengthen the stability of the second retaining structure 126. An annular groove 1235 for filling with soft adhesive is formed on the side of the connecting platform 1231 near the mounting base 110 and recessed inward along its outer peripheral sidewall. The soft adhesive filled in the annular groove 1235 forms part of the structure of the mounting base 110 and is used to strengthen the stability of the structure of the mounting base 110.

[0064] like Figure 8As shown, in some specific embodiments, the connecting frame 1232 is configured as a sleeve structure extending from the connecting platform 1231 in a direction away from the mounting base 110. The mounting end 10 is detachably sleeved within the sleeve structure and can rotate relative to the fourth connecting member 124 about the second axis Y to adjust the rotation angle of the second connecting member 122 relative to the third connecting member 123. The fourth connecting member 124 is threadedly sleeved with the outer wall of the sleeve structure along the second axis Y. When the fourth connecting member 124 is locked relative to the third connecting member 123, the mounting end 10 is supported and limited between the second limiting surface 1261 and the second mating surface 12. The mounting base 110 presses against the top pressure ring 1242 and the external medium surface, and can drive the sleeve structure to move along the second axis Y in a direction away from the mounting base 110 when the fourth connecting member 124 rotates helically relative to the sleeve structure, so as to pull the middle part of the mounting base 110 of the top pressure ring 1242 to deform and bulge in a direction away from the external medium surface to form the vacuum adsorption cavity.

[0065] like Figure 10 , Figure 11 As shown, in another embodiment of this utility model, the second retaining structure 126 is supported and positioned on the third connecting member 123. The first mating surface 11 is configured as a toothed surface structure, and the second mating surface 1261 is configured as a toothed surface structure that matches the first mating surface 11. When the fourth connecting member 124 is locked relative to the third connecting member 123 by spiral rotation, the second mating surface 1261 can engage with the first mating surface 11 to prevent the second connecting member 122 from rotating relative to the third connecting member 123 around the second axis Y. The second retaining structure 126 and the connecting platform 1231 are configured as an integral structure. The first mating surface 11 is configured as an annular toothed surface structure arranged around the second axis Y, and the second mating surface 1261 is configured as an annular toothed surface structure that matches the first mating surface 11. The second connecting member 122 can engage with the second mating surface 1261 from different angles through the first mating surface 11 when it is at different angles of rotation relative to the third connecting member 123 to prevent the second connecting member 122 from rotating relative to the second retaining structure 126 around the second axis Y. Mounting base 110 and connecting platform 1231 can be fixedly connected by adhesive or other structures.

[0066] As another embodiment of the present invention, the sunshade 200 further includes a second sunshade extending downward from one or both sides of the first sunshade 210 along its length direction. The second sunshade is used to block sunlight shining from the side of the sunshade device, thereby increasing the sunshade area of ​​the sunshade device.

[0067] like Figures 12-14As shown, as another embodiment of the present invention, a vehicle sunshade mechanism is also provided, including a sunshade curtain 200 and a mounting frame 100. The sunshade curtain 200 includes a first sunshade portion 210 for blocking sunlight penetrating the windshield 300. The first sunshade portion 210 has a first side edge 211 and a second side edge 212 respectively arranged on its left and right sides along its periphery, which correspond to the left and right sides of the vehicle. The mounting frame 100 mounts the sunshade 200 onto the windshield 300. The mounting frame 100 includes two or more support frames, each support frame including a mounting base 110 connected to the windshield 300 and a support rod 130 connected at one end to the mounting base 110 via a connecting assembly 120. The support rod 130 of one support frame is arranged along a first side edge 211 and connects to and opens one side of the first sunshade 210 along the first side edge 211. The support rod 130 of the other support frame is arranged along a second side edge 212 and connects to and opens the other side of the first sunshade 210 along the second side edge 212. The support rod 130 can be switched between a first support position A and a second support position B relative to the mounting base 110 via the connecting assembly 120 to adjust the tilt angle of the first sunshade 210 relative to the surface of the windshield 300, thereby adjusting the sunshade angle of the first sunshade 210. When the support rod 130 is in the first support position A, the end of the support rod 130 away from the mounting base 110 is away from the surface of the windshield 300. When the support rod 130 is in the second support position B, the end of the support rod 130 away from the mounting base 110 is close to the surface of the windshield 300. The connecting assembly 120 includes a first retaining structure 125 that can keep the support rod 130 in the first support position A or the second support position B. In this embodiment, the shading angle of the first sunshade 210 is adjusted and positioned by switching the support rod 130 relative to the mounting base 110 between the first support position A and the second support position B. The two support rods 130 are arranged and connected along the first side edge 211 and the second side edge 212 of the first sunshade 210, respectively. The support rods 130 are less likely to interfere with the driver's vision, thereby reducing the interference of the vehicle sunshade mechanism with the driver's vision and making it safer to use. The mounting base 110 is detachably connected to the inner surface of the windshield 300. The entire vehicle sunshade mechanism can be installed simply by detaching the mounting base 110 of the support frame to the inner surface of the windshield 300. The entire vehicle sunshade mechanism can be disassembled by removing the mounting base 110 of the support frame from the inner surface of the windshield 300. The installation and disassembly are more convenient and easier to use.Of course, in other embodiments, the mounting base 110 can also be detachably connected to the frame 400 or the dashboard 500, which can also realize the installation or removal of the vehicle sunshade mechanism relative to the vehicle; or the mounting base 110 can be fixedly connected to the windshield 300, the frame 400 or the dashboard 500, or the mounting base 110 can be set as part of the structure of the frame 400 or the dashboard 500, so that the vehicle sunshade mechanism is set as part of the vehicle structure.

[0068] like Figure 12 , Figure 13 As shown, in some specific embodiments, when each support rod 130 is in the first support position A, it can open and support the first sunshade 210 at the first sunshade angle. When each support rod 130 is in the second support position B, it can open and support the first sunshade 210 at the second sunshade angle. The shading area of ​​the first sunshade 210 when it is in the first sunshade angle is smaller than the shading area of ​​the first sunshade 210 when it is in the second sunshade angle. Thus, by switching the support rod 130 between the first support position A and the second support position B, the first sunshade 210 can be switched between the first sunshade angle and the second sunshade angle, thereby adjusting the size of the shading area of ​​the first sunshade 210 to suit drivers of different heights.

[0069] In some specific embodiments, the connecting assembly 120 connects the lower end of the support rod 130 to the mounting base 110. When the first sunshade 210 is at the first sunshade angle, the height of the end of the support rod 130 away from the mounting base 110 is lower than the height of the end of the support rod 130 away from the mounting base 110 when the first sunshade 210 is at the second sunshade angle. A first visualization area E for viewing the outer side of the windshield 300 and the outer side mirror 700 of the side windshield 600 is formed between the upper surface of the first sunshade 210 and the surface of the windshield 300 and the frame 400. A second visualization area F for viewing the dashboard 500 is formed below the lower surface of the first sunshade 210, facilitating sun shading when the vehicle is in motion. When the first sunshade 210 is at the second sunshade angle, the sunshade area is larger, facilitating sun shading when the vehicle is parked. The first sunshade 210 can block sunlight that penetrates the surface of the windshield 300. When the first sunshade 210 is at the first sunshade angle, it can block sunlight that penetrates the surface of the windshield 300, preventing sunlight from penetrating the surface of the windshield 300 and shining on the surface of the dashboard 500, the front seat, the driver's legs, or the passenger's legs. This prevents the dashboard 500 from being damaged by sun exposure while the vehicle is in motion, thus improving vehicle safety and enhancing the coolness of the driver's cabin and front seats while the vehicle is in motion. It can also provide sun protection for the lower bodies of the driver and passenger. When the first sunshade 210 is at the second sunshade angle, it can block sunlight that penetrates the surface of the windshield 300, preventing sunlight from penetrating the surface of the windshield 300 and shining into the driver's cabin. This prevents the dashboard 500 from being exposed to sun exposure when the vehicle is parked and enhances the coolness of the driver's cabin while the vehicle is in motion. Furthermore, when the first sunshade 210 is at the second sunshade angle, the upper end of the first sunshade 210 can be further supported by the sunshade panel 800 to ensure that the first sunshade 210 is maintained at the second sunshade angle. The driver's console 500 includes a console base, steering wheel, instrument panel, display screen, and other structures.

[0070] In some specific embodiments, the sunshade 200 is made of soft fabric. On the one hand, this prevents the driver from being injured by impacting the sunshade during sudden braking or other reasons while driving, thus improving safety when using sunshade while the vehicle is in motion. On the other hand, the soft fabric can deform and fold to reduce its space occupation, making it convenient to store the sunshade 200. The support rod 130 is configured as a telescopic rod assembly. The first sunshade part 210 can be unfolded to the sunshade state via the telescopic rod assembly connected to the first side edge 211 and the telescopic rod assembly connected to the second side edge 212. The first side edge 211 and the second side edge 212 can deform and converge as the telescopic rod assembly connected to them shortens, thereby causing the first sunshade part 210 to retract to the stored state. This facilitates quick switching between the sunshade state and the stored state, allowing the sunshade 200 to be quickly retracted when the vehicle is driving at night, or quickly unfolded when the vehicle is driving or parked during the day. In this embodiment, the telescopic rod assembly includes multiple telescopically connected sleeve rods, which facilitates extension or shortening and provides good stability for supporting the first sunshade 210. In other embodiments, the telescopic rod assembly can also be configured as other structures that can be extended and shortened.

[0071] In some specific embodiments, after the vehicle sunshade mechanism is installed on the vehicle, the lower end of the first sunshade 210 is spaced apart from the surface of the windshield 300 to form a defogging channel for airflow, thus avoiding interference with normal defogging operations while the vehicle is in motion. The first sunshade 210 has a working window that does not obstruct the operation of functional components such as the head-up display on the driver's console 500, thereby ensuring the normal operation of these components while the vehicle is in motion.
