The side window sunshade curtain 1 of the longitudinally unfolding and folding type includes a side window cloth curtain retracting shaft tube group 11 and a side window cloth curtain 10. The side window cloth curtain retracting shaft tube group 11 is transversely arranged below the side window. The side window cloth curtain 10 is connected to the side window cloth curtain retracting shaft tube group 11. The side window cloth curtain retracting shaft tube group 11 can automatically retract the side window cloth curtain 10. The side window cloth curtain 10 has a cloth curtain movable side panel 101, and can drive the side window cloth curtain 10 to unfold and retract by operating the cloth curtain movable side panel 101 to rise and fall.

[0089] like Figures 1 to 3 As shown, the corner window sunshade 2 is a sunshade of the transversely unfoldable and foldable type, which includes a corner window curtain 20, a corner window curtain retracting shaft tube group 21 and a corner window curtain driving component 22. The corner window curtain retracting shaft tube group 21 is longitudinally arranged at the longitudinal rod between the side window and the triangular window. The corner window curtain retracting shaft tube group 21 can automatically retract the corner window curtain 20. The corner window curtain 20 has a curtain movable side plate 201. The corner window curtain driving component 22 includes a transverse slide rail 221 and a rocker arm 222. The transverse slide rail 221 is installed below the triangular window. The upper end of the rocker arm 222 is pivotally connected to the curtain movable side plate 201 of the corner window curtain 20. The lower end of the rocker arm 222 has a slider 223 that can move in the transverse slide rail 221. The rocker arm 222 is operated to move laterally along the transverse slide rail 221 and combine with the corner window curtain retracting shaft tube group 21 to drive the corner window curtain 20 to unfold and fold.

[0090] like Figures 1 to 3 In the embodiment shown, the cloth curtain linkage electric driving device 3A of the present invention can be assembled with the side window sunshade curtain 1 that can be longitudinally expanded and retracted and the corner window sunshade curtain 2 that can be transversely expanded and retracted, and can drive the side window cloth curtain 10 and the corner window cloth curtain 20 to be synchronously expanded and retracted. The cloth curtain linkage electric driving device 3A includes a driving mechanism 30, two longitudinal slide rails 40, a pull-wire side window cloth curtain driving mechanism 50 and a pull-wire corner window cloth curtain driving mechanism 60.

[0091] like Figures 1 to 3As shown, the driving mechanism 30 includes a transmission shaft 31 and an electric driving unit 32. The transmission shaft 31 passes through the side window cloth curtain retracting shaft tube group 11 horizontally. In this embodiment, the height position of the transverse slide rail 221 is higher than the height position of the side window cloth curtain retracting shaft tube group 11, and the transmission shaft 31 extends to the bottom of the transverse slide rail 221. The electric driving unit 32 is connected to the transmission shaft 31 and can drive the transmission shaft 31 to rotate forward and reverse. The electric driving unit 32 includes a motor 321 and a transmission assembly 322, and the transmission assembly 322 is connected between the motor 321 and the transmission shaft 31. In this embodiment, the driving mechanism 30 also includes a protective shell 323, which is arranged between the motor 321 and the transmission shaft 31 and is sleeved on the outer side of the transmission assembly 322.

[0092] The transmission component 322 can be a combination of a worm wheel 3221 and a worm 3222 or a gear train transmission component 322 such as a gear set. In the present embodiment, the transmission component 322 uses a combination of a worm wheel 3221 and a worm 3222, and the rotor of the motor 321 is connected with the worm 3222. The worm wheel 2221 is mounted on the transmission shaft 31 and meshes with the worm 3222, so that the motor 321 can reduce the speed and drive the transmission shaft 31 to rotate through the transmission component 322 composed of the worm 3222 and the worm wheel 3221.

When the electric driving unit 32 drives the transmission shaft 31 to rotate forward and reverse, the side window curtain retracting shaft tube assembly 11 is also driven to rotate and generate lateral displacement, so that the unfolded side window curtain 10 can move to match the shape of the side window.

[0094] like Figure 1 , Figure 4 and Figure 5As shown, in this embodiment, the shaft tube rotating assembly 33 includes a driven rotating member 331, a rotating guide seat 332 and a connecting member 333. The driven rotating member 331 is assembled at one end of the side window curtain winding shaft tube assembly 11 and is sleeved on the outside of the transmission shaft 31 so as to be able to be linked. The driven rotating member 331 has a spiral portion 3310. The rotating guide seat 332 is arranged on the outside of the driven rotating member 331 and has a spiral guide groove 3320. The driven rotating member 331 is screwed in the spiral guide groove 3320 of the rotating guide seat 332 with the spiral portion 3310. The connecting member 333 is fixedly connected to the transmission shaft 31. In this embodiment, the driven rotating member 331 is provided with an axial hole, which is a non-circular hole that is polygonal in end view. The outer circumferential surface of the connecting member 333 matches the shape of the axial hole. The driven rotating member 331 is sleeved on the outer side of the connecting member 333 and can move along the axial direction. When the electric driving unit 32 drives the transmission shaft 31 to rotate forward and reverse, the side window curtain 10 can be driven to rotate forward and reverse through the guiding effect of the shaft tube rotating assembly 33. The driven rotating member 331 is screwed into the spiral guide groove 3320 of the rotating guide seat 332 with the spiral portion 3310, so that the side window curtain 10 connected to the side window curtain winding shaft tube group 11 can rotate and move along the axial direction of the transmission shaft 31 (front and rear lateral movement), so that the unfolded side window curtain 10 can match the shape of the side windows with unequal widths up and down, providing a better sunshade effect for the side windows.
