Specific embodiments

[0037] The following further details the present utility model with reference to the accompanying drawings.

[0038] Refer to Figure 1 and Figure 2 , a curtain that can be applied to an automobile to shade and block light from the automobile window, and can also be applied to places where shading and light blocking are required.

[0039] The curtain includes fan bones and a fan surface 3 mounted on the fan bones. The fan surface 3 can be driven by the fan bones to expand in a fan - shaped manner. The curtain has an unfolded state and a stored state, and the area of the curtain in the unfolded state is larger than the area of the curtain in the stored state. When in the unfolded state, the curtain is placed on the window of the automobile to achieve the purpose of shading. When in the stored state, the volume of the curtain is small, which is convenient for storage. The transformation between the stored state and the unfolded state is realized through the fan bone structure, which is convenient to use.

[0040] There are at least two fan bones, and at least part of the fan surface 3 can be stored between the fan bones.

[0041] For example, the fan bones may have two main fan bones and multiple sub-fan bones. The multiple sub-fan bones are arranged between the two main fan bones. The two main fan bones are the first main fan bone 1 and the second main fan bone 2 respectively. There may be five sub-fan bones, namely the first sub-fan bone 5, the second sub-fan bone 6, the third sub-fan bone 7, the fourth sub-fan bone 8, and the fifth sub-fan bone 9. According to the size of the unfolded area, the number of sub-fan bones can be appropriately set. That is, when the unfolded area is larger, the number of sub-fan bones is more; when the unfolded area is smaller, the number of sub-fan bones is less, and even the sub-fan bones may not be set, and the unfolding and storage are directly realized by the two main fan bones.

[0042] The curtain has a rotating shaft 4, and at least two fan bones are stacked on the rotating shaft 4, and at least two fan bones rotate around the rotating shaft. The transformation between the unfolded state and the stored state is realized by the rotation between the fan bones.

[0043] Specifically, the rotating shaft 4 can be arranged at one end of the fan bone away from the fan surface 3.

[0044] The fan surface can be fan-shaped unfolded around the rotating shaft 4 as the fan bones rotate. The length of the fan bones is greater than the radial length of the fan surface 3 connected to the fan bones, so that the fan surface 3 is stably connected to the fan bones, and the fan surface 3 can be adhesively bonded to the fan bones with glue.

[0045] In order to improve the sunshade effect, the fan surface 3 has a reflective layer, and the reflective layer is located on the outer side of the fan surface 3.

[0046] The fan surface 3 has a heat-insulating layer, and the heat-insulating layer is located below the reflective layer.

[0047] The lengths of the fan bones are not all equal. For example, the lengths of the two main fan bones and the multiple sub-fan bones are all equal, forming a regular fan shape; for example, the lengths of the two main fan bones are equal, but the multiple sub-fan bones are not equal, and the multiple sub-fan bones can be set to gradually become longer and then gradually become shorter in sequence, forming a convex shape in the middle; for example, each main fan bone and each sub-fan bone are not equal. The length of the first main fan bone 1 is shorter, and the length of the second main fan bone 2 is longer. The multiple sub-fan bones are set to gradually become longer from the first main fan bone 1 to the second main fan bone 2. According to the shape of the car window, the lengths of the fan bones can be appropriately set to match the shape of the window.

[0048] A locking member can be arranged between two fan bones, and the adjacent two fan bones can be positioned through the locking member.

[0049] The locking member can be a part with magnetism, and the positioning of the positions between adjacent two fan bones is achieved through the attraction of magnetism. For example, magnetic parts 20 that match each other are provided on adjacent two fan bones.

[0050] In the storage state, the locking member can limit the positions between the fan ribs; in the fully unfolded state, the locking member is ineffective. However, in some cases, when the window area is small and the curtain does not need to be fully unfolded but only semi-unfolded, there are still at least two adjacent sub-fan ribs in a stacked state. At this time, the locking member can limit the sub-fan ribs in this stacked state to a certain extent, so as to limit or maintain the semi-unfolded shape of the curtain.

[0051] Optionally, both the main fan rib and the sub-fan rib can be directly provided with grooves for placing the magnetic part 20, and the magnetic part 20 is embedded in the groove.

[0052] Optionally, referring to Figure 3 , both the main fan rib and the sub-fan rib can be provided with a fixed groove plate 10, and the corresponding magnetic part 20 is placed on the fixed groove plate 10.

[0053] The curtain further includes a fixing member, and the fixing member can be connected to the main fan rib, so that the main fan rib is detachably connected to the window through the fixing member.

[0054] Referring to Figure 3 , Figure 6 and Figure 7 , a suction cup 21 is arranged below the bottom of the rotating shaft 4. The suction cup 21 can suck the window. An internal thread groove 16 is arranged at the top of the suction cup 21. The bottom of the rotating shaft 4 is fixedly connected with an external thread head 23, and the internal thread groove 16 and the external thread head 23 are threadedly connected. The suction cup 21 and the rotating shaft 4 can be of a split structure. Of course, the suction cup 21 can also be directly connected to the first main fan rib 1 or the second main fan rib 2, and the suction cup 21 is arranged close to the rotating shaft 4. In this way, when blocking sunlight on the front windshield, the user can complete the entire laying, unfolding and other operations only on one side of the vehicle.

[0055] Referring to Figure 8 , the main fan rib has a handle 24, and the handle 24 can be arranged on the first main fan rib 1 or the first main fan rib 2, which is convenient for the user to store and unfold.

[0056] The end of the fan rib is made of a flexible material, that is, the end of the fan rib can be bent and deformed or has a certain elasticity, so as to adapt to different surfaces.

[0057] The maximum angle of the curtain unfolding is less than 270°, that is, from the storage state to the unfolded state, the maximum rotation angle of the second main fan rib 2 is less than 270°. This can be set according to the specific fan shape of the fan surface 3.

[0058] Referring to Figures 3 to 5, a round block 11 is installed on one side of the bottom of the second main fan bone 2 away from the rotation axis 4, a buckle frame 14 is installed on one side of the bottom of the first main fan bone 1 away from the rotation axis 4, a buckle groove 12 is arranged on the side of the round block 11 close to the first main fan bone 1, the buckle frame 14 is engaged with the buckle groove 12, threaded grooves 13 are arranged in the middle of the buckle frame 14 and the buckle groove 12, and the two threaded grooves 13 are both threadedly connected with a threaded insertion rod 15. When the second main fan bone 2 is folded and combined towards the first main fan bone 1, by inserting the buckle frame 14 into the buckle groove 12 and sequentially threadedly fixing the threaded insertion rod 15 into the threaded grooves 13 on the buckle frame 14 and the buckle groove 12 for fixation, after the second main fan bone 2 is folded on the first main fan bone 1, it is fixed and not easy to scatter, which is convenient for storage.

[0059] Fixing gaskets 17 are sleeved on the upper part of the second main fan bone 2 and the lower part of the first main fan bone 1 on the rotation axis 4. The fixing gaskets 17 are for fastening the second main fan bone 2 and the first main fan bone 1. A pull ring 18 is installed on the upper part of the rotation axis 4, which is convenient for lifting the whole curtain

[0060] The above discloses only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the creative concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the utility model.
