[0084] Furthermore, such as Figure 19 As shown, the front sunshade spring roller 43 has a round hole in the middle. The head of the front sunshade spring roller 43 is connected to the front sunshade retractor 33, and the connecting section with the head has a spiral groove in the circumference. During the stretching process, the inner diameter of the front sunshade retractor 33 decreases until it is locked with the front sunshade spring roller 43, which then drives the left spiral end 47 of the front sunshade to rotate. Because the spiral groove of the front sunshade spring roller 43 is connected to the head, the spiral groove of the front sunshade spring roller 43 is connected to the head. Figure 21 The front sunshade short helical spring 48 shown is connected, which will drive the front sunshade short helical spring 48 to rotate; by setting the stall torque of the front sunshade motor 12 and the rotation torque of the front sunshade short helical spring 48 to achieve balance, it can ensure that the sunshade is tightly sealed when closed, and can avoid the front sunshade motor 12 over-travel rotation causing the front sunshade retractor 33 to be overstretched and irreversible.

[0085] like Figure 23 The front sunshade support short shaft 49 shown is the common support shaft for the front sunshade spring roller 43, the front sunshade short spiral spring 48, the front sunshade roller sleeve 32, and the front sunshade retractor 33; as shown Figure 22 The front sunshade support shaft 46 shown serves as the common support shaft for the front sunshade right-hand spiral end 42, the front sunshade spring roller 43, the front sunshade long spiral spring 44, the front sunshade support roller 45, the front sunshade roller sleeve 32, and the front sunshade retractor 33. This embodiment, through the combination of a long shaft and a short shaft with a long spring and a short spring structure, achieves better retraction and support effects.

[0086] In this embodiment, the front sunshade spring roller 43 is made of foam material for wrapping such as Figure 20 The front sunshade long spiral spring 44 shown, the front sunshade roller sleeve 32 can rotate around the front sunshade spring roller 43, and at the same time the front sunshade long spiral spring 44 can also rotate around... Figure 18 The spiral groove at the right spiral end 42 of the front sunshade shown rotates; the front sunshade spring cylinder 43 can support the front sunshade roller sleeve 32, and can also prevent the long spiral spring 44 of the front sunshade from directly contacting and rubbing against the front sunshade roller sleeve 32. The foam material can also absorb the noise caused by rotation.

[0087] The rear sunshade retraction mechanism includes a rear sunshade retractor 31, a rear sunshade roller sleeve 30, a rear sunshade short spiral spring 40, a rear sunshade long spiral spring 36, a rear sunshade spring roller 35, a rear sunshade support long shaft 38, a rear sunshade support roller 37, and a rear sunshade support short shaft 41. Figure 16 The left spiral end 34 of the rear sunshade shown is as follows: Figure 17The rear sunshade curtain right screw end 39 is shown, which has the same structure as the front sunshade curtain winding mechanism, and will not be described here.

[0088] The double sunshade curtain structure of the front sunshade curtain 4 and the rear sunshade curtain 5 can reduce the diameter of the single sunshade curtain reel, and the reel structure is arranged at the junction position of the two sunshade curtains, without occupying the head space of the front row or the second row, and without affecting the view of the driver and the passenger. The front sunshade curtain 4 and the rear sunshade curtain 5 are respectively configured with a motor, which can be used to open the two sunshade curtains at the same time, or to open the sunshade curtains of the front row or the rear row separately, to meet the different needs of the front row and the rear row passengers.

[0089] The double motors of the embodiment are arranged at the front end, which simplifies the rear end structure of the sunshade curtain without affecting the view of the front row passengers, and does not need more structures; the pull rope mechanism is completely built-in the guide rail, the rear end structure of the sunshade curtain can be made thinner in the Z direction, to improve the head space of the rear row passengers, and the rear end structure can be made shorter in the X direction, to increase the X direction light transmittance of the sunshade curtain, so that the rear row has a larger light transmittance area.

[0092] The specific control process is as follows:

[0093] (1) In the first working state, the front sunshade curtain 4 and the rear sunshade curtain 5 are wound at the same time (full opening):

[0094] As shown in Figures 24-26 , the front sunshade curtain motor 12 rotates clockwise, and the rear sunshade curtain motor 13 rotates counterclockwise, the transmission gear of the front sunshade curtain motor 12 drives the front sunshade curtain left pull rope 14 to move left and backward, and at the same time, the front sunshade curtain right pull rope 16 moves right and backward, thereby driving the front sunshade curtain 4 to move backward and wind to the opened state; the transmission gear of the rear sunshade curtain motor 13 drives the rear sunshade curtain left pull rope 15 to move right and forward, and at the same time, the rear sunshade curtain right pull rope 17 moves left and forward, thereby driving the rear sunshade curtain 5 to move forward and wind to the opened state.

[0095] (2) In the second working state, the front sunshade curtain 4 and the rear sunshade curtain 5 are maintained to be unfolded at the same time (full closing):

[0096] As shown in Figure 27As shown, the front sunshade motor 12 and the rear sunshade motor 13 keep the front sunshade 4 and the rear sunshade 5 fully extended to cover the panoramic glass via corresponding pull cords.

[0097] (3) In the third working state, the front sunshade 4 rolls up and the rear sunshade 5 unfolds (front open, rear closed):

[0098] like Figures 28-30 As shown, the front sunshade motor 12 rotates clockwise, and the transmission gear of the front sunshade motor 12 drives the left pull cord 14 of the front sunshade to move to the left and backward, while simultaneously driving the right pull cord 16 of the front sunshade to move to the right and backward, thereby driving the front sunshade 4 to move backward and roll up to the open state; the rear sunshade motor 13 prevents the rear sunshade 5 from rolling up, maintaining it in the open (closed) state.

[0099] (4) In the fourth working state, the front sunshade 4 is unfolded and the rear sunshade 5 is rolled up (front closed, rear open):

[0100] like Figures 31-33 As shown, the rear sunshade motor 13 rotates counterclockwise. The transmission gear of the rear sunshade motor 13 drives the left pull cord 15 of the rear sunshade to move to the right and forward, and at the same time drives the right pull cord 17 of the rear sunshade to move to the left and forward, thereby driving the rear sunshade 5 to move forward and roll up to the open state. The front sunshade motor 12 keeps the front sunshade 4 from rolling up, maintaining it in the open (closed) state.
