[0044] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0045] It should be understood that the terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "a", "an", and "said" as used herein may also be meant to include plural forms. The terms "comprise", "include", and "have" are inclusive and therefore specify the presence of stated features, elements, and / or components, but do not exclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.

[0046] Although the terms first, second, etc. may be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms may only be used to distinguish one element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text. In addition, in the description of this application, unless otherwise clearly specified and limited, the terms "set" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0047] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature as shown in the figure, such as "outer", "end", "upper", "lower", "high", "lower", "inner", "middle", "side", "axial", "first direction", "second direction", etc. Such spatial relative terms are intended to include different orientations of the mechanism in use or operation in addition to the orientation depicted in the figure. For example, if the mechanism in the figure flips, the element described as "below other elements or features" or "below other elements or features" will then be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The mechanism may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used in the text are interpreted accordingly.

[0048] At present, with the development of automobile technology, transparent panoramic skylight covers are becoming more and more popular. This type of skylight cover has a wider field of view above and is more beautiful.

[0049] However, in summer, strong sunlight will directly penetrate the roof of the car into the interior, causing users to feel "baked". Therefore, users need to install sunshades themselves after purchasing the car, which leads to cumbersome installation work. In addition, the sunshades are only used for sunshade purposes after installation, and users only use them in hot weather, resulting in low utilization rate of sunshades during the car life cycle and low cost performance.

[0050] In addition, in the related art, the curtain body forms a projection screen from the trunk at the rear end of the vehicle, requiring the user sitting in the front seat to turn his head to look backward. The space in the front seat is small, and the comfort of turning the head to watch for a long time is poor.

[0051] like Figures 1 to 12 As shown, in order to at least solve the technical problem that "in the related art, the sunshade used for the transparent panoramic skylight cover is only used to block the sunlight, with low utilization rate and low cost performance", the embodiment of the present application proposes a vehicle sunshade device and a vehicle having the same.

[0054] In detail, in the present application, the vehicle blind device includes a rolling blind mechanism 200 and a blind body 300. The rolling blind mechanism 200 is pre-installed on the vehicle roof 100 and can roll up and store the blind body 300, eliminating the need for users to perform installation operations after purchasing the vehicle, and making it convenient to store after use. In addition, the blind body 300 can be switched between sunshade and projection modes to meet the diverse needs of users, enhance user experience, and have a high cost-performance ratio. Moreover, the blind body 300 forms a projection screen from the front end of the vehicle, making it convenient for users to sit in the back seat 500 to watch the projected content. The movie-watching preparation process is simple and in line with user habits.

[0055] It should be noted that the rolling shutter mechanism 200 preferably extends in the width direction of the vehicle. Considering the assembly and avoidance relationship with other structures of the vehicle, the rolling shutter mechanism 200 can be appropriately tilted according to actual conditions.

[0056] Furthermore, in some embodiments, the rolling shutter mechanism 200 includes a storage bin 210 and a rotating shaft disposed inside the storage bin 210. The rotating shaft can rotate around itself electrically or manually, and the storage bin 210 is provided with an opening; the two ends of the curtain body 300 are respectively a connecting end and a free end, and the connecting end passes through the interior of the storage bin 210 from the opening and is connected to the rotating shaft, thereby realizing the storage and extension of the curtain body 300 through the rotation of the rotating shaft, wherein, when the curtain body 300 is extended, it is also necessary to cooperate with a force pulling the free end outward.

[0067] Further preferably, the flange 432 is a continuous structure along the circumference of the main body 431 of the driving key 430 , thereby enhancing the strength of the flange 432 .

[0068] It should be noted that the flange 432 may also be a discontinuous structure provided in the circumference of the main body 431 , as long as it can be limited by the inner side surface of the edge of the shift hole 413 to prevent the driving key 430 from being separated from the shift hole 413 .

[0069] In addition, in some other embodiments, the reset spring 440 may not be provided, and the driving key 430 may be reset by manually pulling it out, which also falls within the protection scope of the present application.
