A first rod 4 and a second rod 5 are provided, and the transmission mechanism 1 drives the first rod 4 and the second rod 5 to rotate. When the sunshade cloth assembly 2 needs to be raised, the first rod 4 and the second rod 5 rotate to drive the two ends of the sunshade cloth assembly 2 away from the reel 6 to move respectively in the first direction D1 and the second direction D2; when the sunshade cloth assembly 2 needs to be rolled up, the two ends move respectively in the opposite direction of the first direction D1 and the opposite direction of the second direction D2.

[0072] In one embodiment, the third rod 21 includes a curved section, and the curved section is curved and protrudes toward a direction close to the reel 6 .

[0073] Please refer to Figure 1 The third rod 21 is provided with a curved section and is bent protrudingly toward the direction close to the reel 6, so as to reserve a position for the driving recorder and the rearview mirror inside the car. When the third rod 21 drives the sunshade to move to the top, it will not interfere with the driving recorder and the rearview mirror inside the car.

[0074] In one embodiment, the third rod 21 includes a first sub-rod 211 and a second sub-rod 212 connected along its axial direction. The first sub-rod 211 is movably connected to the first rod 4 , and the second sub-rod 212 is sleeved on the outer periphery of the first sub-rod 211 .

[0075] Please refer to Figure 1 and Fig.10 The first sub-rod 211 is movably connected to the first rod 4. When the vehicle needs sunshade, the driving member 3 outputs power to drive the first rod 4 to rotate, and the first sub-rod 211 moves along the first direction D1, thereby driving the third rod 21 to move. The first sub-rod 211 is axially connected to the second sub-rod 212, and the second sub-rod 212 is sleeved on the outer periphery of the first sub-rod 211. The first sub-rod 211 can slide along the second sub-rod 212, so that the third rod 21 can change its length to adapt to the width at different positions.

[0076] Please refer to Fig.11 , Fig.12 and Fig.13The second sub-rod 212 is sleeved on the outer periphery of the first sub-rod 211, and the first sub-rod 211 slides along the second sub-rod 212. The length of the third rod 21 can be adaptively adjusted according to the width of the windshield, H1>H2>H3. Through the adaptive adjustment of the third rod 21, the third rod 21 can be applied to windshields of different widths or installation environments of different sizes, increasing the diversity of usage scenarios.

[0077] In one embodiment, the second sub-rod 212 includes a fifth section 2121 and a sixth section 2122 connected at an angle, the fifth section 2121 is connected to the first sub-rod 211 , the third rod 21 also includes a third sub-rod 213 , and the sixth section 2122 is sleeved on the outer periphery of the third sub-rod 213 .

[0078] In one implementation, please refer to Fig.14 , a connection setting between the fifth section 2121 and the sixth section 2122, wherein the angle between the fifth section 2121 and the sixth section 2122 is less than 90°.

[0079] In one implementation, please refer to Fig.15 , a connection setting between the fifth section 2121 and the sixth section 2122, and the angle between the fifth section 2121 and the sixth section 2122 is equal to 90°.

[0080] In one implementation, please refer to Fig.16 , a connection setting between the fifth section 2121 and the sixth section 2122, wherein the angle between the fifth section 2121 and the sixth section 2122 is greater than 90°.

[0081] The areas formed by setting different angles can be suitable for driving recorders of different shapes.

[0082] A third sub-rod 213 is provided. When the third rod 21 moves downward to the limit position, the third sub-rod 213 and the second sub-rod 212 move relative to each other, thereby compressing the height of the third rod 21 and reducing the space occupied when the third rod 21 is stored.

[0083] The utility model provides a vehicle, comprising a sunshade device and glass as described in any one of the above implementation modes, wherein the sunshade device is arranged behind the glass.

[0084] The sunshade device can be set behind the front windshield, rear windshield, front door glass, rear door glass and sunroof glass to block direct sunlight and adapt to different lighting conditions.

[0085] In the description of the embodiments of the present application, it should be noted that the orientation or positional relationship of terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inside" and "outside" are based on the orientation or positional relationship described in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0086] What is disclosed above is only a preferred embodiment of the present application, and it certainly cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiment and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
