DETAILED DESCRIPTION

[0048] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in conjunction with the drawings of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the described embodiments of the present application, all other embodiments obtained by a person of ordinary skill in the art without any inventive effort fall within the scope of protection of the present application.

[0049] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0050] As shown in FIGS. 1-9, as one embodiment of the present application, a sunshade device is provided, which comprises a mounting frame body 100 and a sunshade curtain 200, the sunshade curtain 200 comprises a first sunshade part 210 for shielding sunlight, the first sunshade part 210 has a first side edge 211 and a second side edge 212 arranged along the periphery thereof. The mounting frame body 100 is used for mounting the sunshade curtain 200 on an external medium such as a window glass or a window frame, especially for mounting on a vehicle frame or a driver's cab around a front windshield of a vehicle. The mounting frame body 100 comprises two support frames or a plurality of support frames, each of which comprises a mounting seat 110 detachably connected to the external medium, and a support rod 130 connected to the mounting seat 110 by a connecting assembly 120, wherein the support rod 130 of one support frame is arranged along the first side edge 211 and connected and spread open one side of the first sunshade part 210 along the first side edge 211, and the support rod 130 of the other support frame is arranged along the second side edge 212 and connected and spread open the other side of the first sunshade part 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 seat 110 through the connecting assembly 120, so as to adjust the inclination angle of the first sunshade part 210 relative to the surface of the external medium, thereby adjusting the sunshade angle of the first sunshade part 210, when the support rod 130 is in the first support position A, the end of the support rod 130 away from the mounting seat 110 is away from the surface of the external medium, and when the support rod 130 is in the second support position B, the end of the support rod 130 away from the mounting seat 110 is close to the surface of the external medium. Moreover, the connecting assembly 120 comprises a first retaining structure 125 capable of keeping the support rod 130 in the first support position A or the second support position B, and the first sunshade part 210 can be kept at a corresponding sunshade angle by keeping the support rod 130 in the first support position A or the second support position B through the first retaining structure 125. Compared with the prior art solution of adjusting and positioning the sunshade angle of the sunshade curtain by elongating and shortening the telescopic rod arranged at an angle with the sunshade curtain, in the present embodiment, the sunshade angle of the first sunshade part 210 is adjusted and positioned by switching the support rod 130 between the first support position A and the second support position B relative to the mounting seat 110, 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 part 210 respectively, so that the support rod 130 is 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 the use safer, and the structure is simple, only the mounting seat 110 of the support frame needs to be detachably connected to the external medium, so as to realize the mounting of the entire sunshade device, and the mounting seat 110 of the support frame needs to be detached from the external medium, so as to realize the dismounting of the entire sunshade device, making the mounting or dismounting more convenient and easy to use.

[0051] As shown in FIG. 1 and FIG. 2, in some embodiments, each support rod 130 can support the first sunshade part 210 to be opened and supported at a first sunshade angle when the support rod 130 is located at the first support position A, and support the first sunshade part 210 to be opened and supported at a second sunshade angle when the support rod 130 is located at the second support position B. The first sunshade part 210 has a smaller shading area when the first sunshade part 210 is at the first sunshade angle than when the first sunshade part 210 is at the second sunshade angle. Thus, the first sunshade part 210 can be switched between the first sunshade angle and the second sunshade angle by switching the support rod 130 between the first support position A and the second support position B, so as to adjust the size of the shading area of the first sunshade part 210 and adapt to different use scenarios.

[0052] In some embodiments, the connecting assembly 120 is connected between the lower end of the support rod 130 and the mounting base 110. The height of the end of the support rod 130 away from the mounting base 110 is lower when the first sunshade part 210 is at the first sunshade angle than when the first sunshade part 210 is at the second sunshade angle. When the first sunshade part 210 is at the first sunshade angle, a first visual area E for looking up above the first sunshade part 210 is formed between the upper surface of the first sunshade part 210 and the surface of the external medium. When the sunshade device is installed in a vehicle, the first visual area E can be used to look at the outside of the front windshield, the side windshield, and the rearview mirror. A second visual area F for looking down below the first sunshade part 210 is formed below the lower surface of the first sunshade part 210. When the sunshade device is installed in a vehicle, the second visual area F can be used to look at the driver's seat, which is convenient for using the sunshade device to provide shade when the vehicle is running. When the first sunshade part 210 is at the second sunshade angle, the sunshade area is larger, which is convenient for using the sunshade device to provide shade when the vehicle is parked. The first sunshade part 210 can block sunlight that penetrates the surface of the external medium. When the sunshade device is installed in a vehicle and the first sunshade part 210 is at the first sunshade angle, the first sunshade part 210 can block sunlight that penetrates the surface of the front windshield, so as to prevent the sunlight from penetrating the surface of the front windshield and then shining on the surface of the driver's seat or the front seat or the driver's legs or the copilot's legs, thereby preventing the driver's seat from being damaged due to exposure to sunlight when the vehicle is running, improving the safety of the vehicle, and improving the cool feeling in the driver's cabin and the front seat when the vehicle is running. The first sunshade part 210 can also block sunlight that penetrates the surface of the front windshield, so as to prevent the sunlight from penetrating the surface of the front windshield and then shining into the driver's cabin, thereby preventing the driver's seat from being exposed to sunlight when the vehicle is parked, and improving the cool feeling in the driver's cabin when the vehicle is running. It is agreed that the driver's seat includes a driver's seat base, a steering wheel, an instrument panel, a display screen, and the like.

[0053] As shown in FIG. 4, in some embodiments, the first side edge 211 and the second side edge 212 are arranged on both sides of the first sunshade part 210 in the length direction, and the first sunshade part 210 can be unfolded to a sunshade state by the support rod 130 connected with the first side edge 211 and the support rod 130 connected with the second side edge 212, which is simple and practical. In other embodiments, the first side edge and the second side edge can also be arranged along adjacent or non-adjacent side edges of the first sunshade part 210 and arranged at an angle, which is greater than 0° and less than 90°, or greater than 90° and less than 180°, and the first sunshade part 210 can also be unfolded to a sunshade state by the support rod 130 connected with the first side edge 211 and the support rod 130 connected with the second side edge 212.

[0054] In some embodiments, the sunshade curtain 200 is made of soft fabric, which can prevent the driver from being injured by hitting the sunshade curtain during driving due to sudden braking, thereby improving the safety of the sunshade during driving. On the other hand, the soft fabric can be deformed and folded to reduce the occupied space, thereby facilitating the storage of the sunshade curtain 200. In addition, the soft fabric can be deformed, so that the relative distance between the first side edge 211 and the second side edge 212 can be adjusted by selectively installing the position of the mounting seat 110 of the support frame connected with the first side edge 211 or the position of the mounting seat 110 of the support frame connected with the second side edge 212 on the external medium, thereby adapting to different sunshade requirements, especially for vehicles with different width front windshields, and the use is more flexible and the application range is wider. In this embodiment, the sunshade curtain 200 is made of soft fabric with sun protection function, such as pearl aluminum film fabric, which has good sun protection effect. In other embodiments, other flexible fabric can also be used.

[0055] As shown in FIG. 3 and FIG. 4, in some embodiments, the support rod 130 is provided as a telescopic rod set, and the first side edge 211 and the second side edge 212 can be deformed and gathered with the telescopic rod set connected therewith shortened, so as to drive the first sunshade part 210 to be folded to a storage state. Thus, after the sunshade device is installed on the external medium, such as a vehicle, the folding and storage of the sunshade curtain 200 can be realized without taking the sunshade device off the vehicle, thereby reducing the tedious operation of frequently installing or dismounting the sunshade device, facilitating the quick switching between the sunshade state and the storage state, and enabling the sunshade curtain 200 to be quickly stored when the vehicle drives at night or the sunshade curtain 200 to be quickly unfolded when the vehicle drives or parks during the day. In this embodiment, the telescopic rod set includes a plurality of sleeve rods which are sequentially and telescopically connected, facilitating the extension or shortening, and having good stability for supporting the first sunshade part 210. In other embodiments, the telescopic rod set can also be provided as other structures capable of being extended and shortened.

[0056] As shown in FIG. 4, in some embodiments, one or more clamping members 150 are detachably connected to the support rod 130 for fixing the relative position of the first sunshade part 210 and the support rod 130. The clamping member 150 is used to prevent the sunshade curtain 200 from sliding relative to the support rod 130, thereby improving the stability of the support of the first sunshade part 210 by the support rod 130. Moreover, different positions of the first sunshade part 210 can be clamped and fixed by the clamping member 150 and the support rod 130, so as to adjust the length, width or shape of the first sunshade part 210, thereby making the sunshade device more widely applicable.

In this embodiment, the clamping member 150 is made of a resin material and has a certain elastic effect, so as to be tightly held on the first sunshade part 210 and the support rod 130 under the elastic force, thereby improving the stability of the clamping member 150 for fixing the relative position of the first sunshade part 210 and the support rod 130, and the structure is simple. In other embodiments, the clamping member 150 can also be provided in a clip structure, which can also be used to fix the relative position of the first sunshade part 210 and the support rod 130.

[0058] As shown in FIG. 4, in some embodiments, the first side edge 211 and the second side edge 212 are formed with a sleeving structure sleeving the support rod 130, thereby further improving the stability of the support of the first sunshade part 210 by the support rod 130 and making the first sunshade part 210 more flat when being unfolded. The first sunshade part 210 can be rolled outside the support rod 130 along the sleeving structure around the support rod 130, so as to adjust the unfolding length of the first sunshade part 210. The first sunshade part 210 can be deformed and rolled up with the shortening of the support rod 130, so as to adjust the unfolding width of the first sunshade part 210, thereby facilitating the adjustment of the unfolding length and width of the first sunshade part 210, adapting to different application scenarios, especially being suitable for vehicles of different models and specifications, and having strong practicality. Moreover, after the length and width of the first sunshade part 210 are adjusted, the relative position of the first sunshade part 210 and the support rod 130 can be fixed by the clamping member 150, so as to keep the first sunshade part 210 at the adjusted length and width.

The side wall of the support rod 130 further outwardly protrudes with the second limiting block 132 arranged on the side of the first limiting block 131 away from the mounting base 110. The anti-collision part 141 is provided with the third limiting block 143, and when the limiting piece 140 is connected on the support rod 130, the top pressing part 142 and the third limiting block 143 are in interference fit between the first limiting block 131 and the second limiting block 132, and the end of the connecting structure can be clamped between the first limiting block 131 and the top pressing part 142. The top pressing part 142 is provided with a plurality of conical protrusions, and the taper angle of the conical protrusions is arranged towards the mounting base 110. Compared with the structure of the top pressing part 142 provided with a ring structure, the structure design of the conical protrusions makes the top pressing part 142 more easily deformed and tightly interference fit between the third limiting block 143 and the end of the connecting structure, so that the fixation of the end of the connecting structure is more stable. Of course, in other embodiments, the top pressing part 142 can also be provided with a ring structure or a plurality of spherical protrusions or other structures, which can also be used for the fixation of the end of the connecting structure.

When the suction cup cover is locked by rotating relative to the third connecting member 123, the third connecting member 123 is moved away from the surface of the external medium, and the middle part of the pressing ring 1242 is deformed to form a vacuum adsorption cavity, thereby adsorbing the mounting base 110 firmly on the surface of the external medium. In this embodiment, by rotating the fourth connecting member 124 relative to the third connecting member 123, the mounting base 110 is adsorbed firmly on the surface of the external medium while the support rod 130 is positioned in the preset shading direction relative to the mounting base 110, so that the fourth connecting member 124 has the dual functions of fixing the second connecting member 122 to the third connecting member 123 and adsorbing the mounting base 110 firmly on the surface of the external medium.
