[0051] (3) A shading device installed on both sides of the installation part, comprising a shading unit and a telescopic unit, wherein:

[0052] 3.1) The shading unit comprises a shading curtain 31, a winding roller 32 for winding the shading curtain 31, and a horizontal pressing rod 33 for clamping the free end of the shading curtain 31. The winding roller 32 is the main storage device of the shading curtain 31, which is fixed inside the installation box 2. Its function is to control the expansion and winding of the shading curtain 31 by rotating the shading curtain 31, and to control the expansion and contraction of the shading curtain 31. The function of the horizontal pressing rod 33 is to clamp the free end of the shading curtain 31 to ensure that the shading curtain 31 remains stable and does not shift during operation. The horizontal pressing rod 33 is connected to the telescopic unit and driven by the telescopic unit to drive the free end of the shading curtain 31 to move in the transverse direction during extension and retraction, and can effectively press the free end of the shading curtain 31 to prevent the shading curtain 31 from being raised or deviated due to wind or uneven tension.

Furthermore, when the shading range is particularly large, or the wind force and other conditions of the application scene are relatively harsh, support rods can also be installed on both sides of the bottom of the horizontal pressing rod 33, which is more conducive to improving the stability of the shading device.

[0055] The bidirectional screw 35, the sliding block 37, the motor 38 and the winding roller 32 are accommodated in the installation box 2. The scissor-type telescopic linkage 34 drives the horizontal pressure rod 33 and the sunshade curtain 31 to extend outward through the openings on both sides of the installation box 2, and after contraction, the horizontal pressure rod 33 closes the openings, which is conducive to protecting the internal components and prolonging the service life of the device.

In order to ensure the stability of the sliding block movement, a guide rod parallel to the bidirectional screw 35 is also installed between the driving mounting frame and the supporting frame, and the two sliding blocks 37 are arranged on the guide rod.

[0056] In addition, the first gear 361 is fixedly installed on one end of the bidirectional screw 35 close to the driving mounting frame, and the second gear 362 is fixedly installed on one end of the winding roller 32 close to the driving mounting frame. The first gear 361 is engaged with the second gear 362, so that synchronous cooperation of the sunshade curtain 31 and the horizontal pressure rod 33 is realized through gear transmission.

[0057] On both sides of the installation part, the telescopic unit can be respectively equipped with a motor 38 to independently drive the bidirectional screw 35 and the winding roller 32 on the respective side. Alternatively, in order to simplify the structure, the sunshade devices on both sides can also share one motor. In this configuration, a third gear is fixed on the bidirectional screw 35 on the other side, and a fourth gear is fixed on the winding roller 32. By driving the first gear 361 through the motor 38, the second gear 362, the third gear and the fourth gear are driven through the gear engagement transmission mode, so as to realize synchronous driving of the sunshade devices on both sides and ensure uniform expansion and contraction of the sunshade curtain 31 on both sides.
