[0015] 2. The card slot is provided with a card strip, and the corresponding protrusion is provided with an L-shaped plate. When the protrusion is clamped with the card slot, the L-shaped plate is in contact with the card strip. This design is equivalent to adding an additional limiting and fixing mechanism, which further prevents the louver from loosening or accidentally coming out in the direction of the card slot, greatly enhancing the stability of the connection between the louver and the plastic body. When the width of the L-shaped plate is less than 1.1 times the length of the card strip, the L-shaped plate and the card strip cannot be connected smoothly, affecting the installation efficiency; when the width of the L-shaped plate is greater than 1.1 times the length of the card strip, the L-shaped plate cannot form a suitable clamping with the card strip, therefore, when the width of the L-shaped plate is 1.1 times the length of the card strip, it is best, which can form a good clamping without affecting the installation efficiency. When the height of the L-shaped plate is less than 2 times the thickness of the card strip, the clamping structure formed is unstable and easy to separate; when the height of the L-shaped plate is greater than 2 times the thickness of the card strip, the cost is increased, and the connection effect between adjacent louvers is affected, therefore, when the height of the L-shaped plate is 2 times the thickness of the card strip, this reasonable size ratio relationship makes the L-shaped plate better withstand the force from all directions after connection, such as when encountering wind and other external forces, it can better evenly distribute the stress, avoid local stress too large causing component damage, and ensure that the connection structure can reliably function for a long time.

[0016] 3. The arc-shaped concave surface is arranged on the side of the plastic body away from the card slot, and an extension plate is arranged between the arc-shaped concave surface and the first connecting hole and the second connecting hole. This design increases the structural strength of the plastic body, allowing it to better distribute stress when the louver is rotated and subjected to external forces, avoiding local deformation. The mounting hole of the fixing structure and the corresponding through hole of the louver facilitate additional fixation using connecting components (such as screws, rivets, etc.). This way makes the connection between the louver and the plastic body more secure and reliable, and during installation, it can be quickly positioned according to the corresponding relationship between the mounting hole and the through hole, improving installation efficiency and reducing installation difficulty, facilitating mass production and assembly. The first connecting hole forms a recess between one end and the plastic body, and the other end extends to the outside of the plastic body. This design provides a suitable mounting space for the rotating shaft, and the recess helps better secure the rotating shaft, preventing it from moving axially during use.

[0017] 4. When the distance between the first limiting groove and the second limiting groove is less than 0.9 times the width of the clamping groove, the louver is prone to shaking and deviation during use; when the distance between the first limiting groove and the second limiting groove is greater than 0.9 times the width of the clamping groove, the strength of the connecting structure of the louver and the plastic part is affected, and the supporting force is reduced, therefore, when the distance between the first limiting groove and the second limiting groove is 0.9 times the width of the clamping groove, the firmness and stability of the connecting structure are enhanced, and the sunshade can be reliably used in various environments. At the same time, when the distance between the first limiting groove and the clamping groove is less than 0.5 times the width of the clamping groove, the louver cannot be better fixed and constrained; when the distance between the first limiting groove and the clamping groove is greater than 0.5 times the width of the clamping groove, the distance is too large, and the connection stability is reduced, therefore, the distance between the first limiting groove and the clamping groove is 0.5 times the width of the clamping groove, which is the best, so that the protrusions and other components corresponding to the louver can be embedded exactly, precise limiting is achieved, the louver is stably constrained from multiple dimensions, and the louver is effectively prevented from shaking and deviating during use, a plurality of reinforcing ribs with different sizes are arranged in the plastic part body, and the structural strength of the plastic part body itself can be significantly improved. The reinforcing ribs and the plastic part body form different regular grooves, the weight of the plastic part body is reduced, and the manufacturing cost is reduced without affecting the structural strength.

[0025] The card slot 3 is provided with a clamping strip 12, and the structure of the card slot 3 comprises a vertical surface 13 arranged on one side of the clamping strip 12 and an arc surface 14 connected with the vertical surface 13, and the protrusion 8 is internally provided with an L-shaped plate 15, which is configured to abut against the clamping strip 12 when the protrusion 8 is clamped with the card slot 3. Such a design is equivalent to adding an additional limiting and fixing mechanism, which further prevents the louver 2 from loosening or accidentally coming out in the direction of the card slot 3, greatly enhancing the stability of the connection between the louver 2 and the plastic part body 1. When the width of the L-shaped plate 15 is less than 1.1 times the length of the clamping strip 12, the L-shaped plate 15 and the clamping strip 12 cannot be smoothly connected, affecting the installation efficiency; when the width of the L-shaped plate 15 is greater than 1.1 times the length of the clamping strip 12, the L-shaped plate 15 cannot form a suitable clamping with the clamping strip 12, therefore, when the width of the L-shaped plate 15 is 1.1 times the length of the clamping strip 12, it is the best, which can form a good clamping without affecting the installation efficiency. When the height of the L-shaped plate 15 is less than 2 times the thickness of the clamping strip 12, the clamping structure formed is unstable and easy to separate from each other; when the height of the L-shaped plate 15 is greater than 2 times the thickness of the clamping strip 12, the cost is increased, and the connection effect between adjacent louvers 2 is affected, therefore, when the height of the L-shaped plate 15 is 2 times the thickness of the clamping strip 12, it is the best.
