[0031] See also Figure 1 The utility model provides a car sunshade, including a base 1, on which a liftable top shell 2 is provided, in which a content cavity 21 is provided, and at both ends of the base 1, a fan bone 32 assembly 3 is provided, and the fan bone 32 assembly 3 includes a positioning column 31 rotatably connected to the base 1, and the positioning column 31 is provided with a plurality of fan bones 32 that can rotate around its axis and rotate toward the outer edge of the top shell 2 to unfold to form a fan surface, and the fan bones 32 are stacked up and down, and the upper and lower fan bones 32 can rotate with each other to form an angle, and a linkage mechanism 33 is provided between adjacent fan bones 32, and a sunshade cloth is laid on the fan bones 32. When in use, the top shell 2 is first raised to a certain height, and then the fan bone 32 assembly 3 is rotated to open to form a sunshade. Figure 1 After the sunshade surface is used, the fan rib 32 assembly 3 is retracted inward until it is completely placed under the container cavity 21. The storage state can be seen in FIG. Figure 2 , and then the top shell 2 is lowered to fit the base 1. In the storage state of this product, the base 1 fits the top shell 2, and the fan rib 32 assembly 3 is located in the container cavity 21 of the top shell 2, providing a protective function through the top shell 2.

[0032] like Figure 3As shown, the base 1 is provided with a first driving motor 11 and a lifting screw 12, the first driving motor 11 is used to drive the lifting screw 12 to rotate, the first driving motor 11 and the lifting screw 12 can be connected by a gear box, a screw nut 13 is sleeved on the lifting screw 12, a connecting plate 14 is fixed on the screw nut 13, and the connecting plate 14 is fixedly connected to the top shell 2, and the screw nut 13 is driven to move up and down by the rotation of the lifting screw 12, thereby driving the top shell 2 to be lifted and lowered.

[0033] like Figure 3 As shown, the base 1 is provided with a plurality of guide rods 15, the connecting plate 14 is provided with a clearance hole 141 and a plurality of guide holes 142, the lifting screw rod 12 is located in the clearance hole 141, the guide rod 15 is slidably connected with the guide hole 142, and the guide rod 15 is used to ensure the stability of the top shell 2 during the upward and downward movement.

[0034] like Figure 1 As shown, a solar panel 22 is provided on the top shell 2, and an energy storage battery is provided in the base 1 or the top shell 2. The solar panel 22 is electrically connected to the energy storage battery. The solar cell can generate electricity through the sun and store the generated electricity for use by various driving components in the awning.

[0035] like Figure 3 As shown, the linkage mechanism 33 includes a plurality of stacked support sheet groups, the support sheet groups are rotatably connected to the positioning column 31, and the support sheet group includes a first support sheet 331 and a second support sheet 332. The linkage effect within the support sheet group is as follows: the first support sheet 331 is located above the second support sheet 332, as shown in FIG. Figure 5 , 6As shown, the first linkage column 3311 and the second linkage column 3312 are staggered on the upper and lower surfaces of the first support piece 331, that is, the first linkage column 3311 and the second linkage column 3312 are not coaxially arranged, and the first linkage groove 3321 and the second linkage groove 3322 are provided on the upper and lower surfaces of the second support piece 332, and the second linkage column 3312 is arranged in the first linkage groove 3321. The first support piece 331 rotates until the second linkage column 3312 abuts against the first linkage groove 3321. At this time, an angle is formed between the first support piece 331 and the second support piece 332, and then the first support piece 331 drives the second support piece 332 to rotate synchronously. The linkage effect between the support sheet groups is as follows: the first linkage column 3311 in the support sheet group located below is arranged in the second linkage groove 3322 of the second support sheet 332 in the support sheet group close to it above. Similarly, until the linkage groove abuts against the first linkage column 3311, the support sheet group located above can drive the support sheet group below to rotate, and the first support sheet 331 in the support sheet group located at the top can be directly driven to rotate by external force. Through the above linkage structure, an angle can be formed between the stacked support sheet groups, and an angle can also be formed between the first and second support sheets 332 in the support sheet. Each support sheet is used in combination with the fan ribs 32 to achieve the effect that the fan ribs 32 can rotate with each other to form an angle. The above is the unfolding of the fan rib 32 assembly 3. When it is folded, the first, second, third, and fourth are respectively abutted against the other end of the linkage groove where they are located, thereby achieving the linkage effect of folding.

[0036] like Figure 3 As shown, the linkage mechanism 33 also includes a top support sheet 333 and a bottom support sheet 334 disposed at both ends of the support sheet group. The top support sheet 333 is fixedly connected to the positioning column 31, and the top support sheet 333 is driven to rotate by the positioning column 31. Figure 7 , Figure 8 A third linkage column 3331 is provided on the lower surface of the top support sheet 333, and a fourth linkage column 3341 is provided on the upper surface of the bottom support sheet 334. The third linkage column 3331 and the fourth linkage column 3341 are respectively arranged in the first and second linkage grooves 3322 on the second support sheet 332 close thereto. The cooperation between the third and fourth linkage columns 3341 and the linkage grooves can refer to the working principles of the first and second linkage columns 3312.

[0037] like Figure 4 As shown, the base 1 is provided with a second driving motor 335, the bottom end of the positioning column 31 is fixed with a driven gear 311, a transmission gear set is provided between the driven gear 311 and the second driving motor 335, and the second driving motor 335 drives the positioning column 31 to rotate through the transmission gear set.

[0038] See also Figure 5 or Figure 6 It can be known that the ends of the first supporting piece 331 and the second supporting piece 332 are provided with fixing holes, and the fan ribs 32 are inserted into the fixing holes.

[0039] like Figure 5 , 6 As shown, the first support sheet 331 is provided with an abutting boss 3313. When the fan bone 32 assembly 3 is folded, the second support sheet 332 is provided with a paving groove 3323 for accommodating the abutting boss 3313, so that the first support sheet 331 and the second support sheet 332 in the storage state can be as close as possible to each other, thereby reducing the storage volume occupied by the support sheet assembly. For specific storage states, please refer to Figure 2 .
