The front sunshade curtain long spiral spring 44 is wound around the outside of the front sunshade curtain supporting long shaft 46, and the front sunshade curtain spring drum 43 is sleeved on the outside of the front sunshade curtain long spiral spring 44; the right end of the front sunshade curtain supporting long shaft 46 is connected to the right spiral end head 42 of the front sunshade curtain, and the left end extends out of the front sunshade curtain spring drum 43, and the front sunshade curtain supporting roller 45 is installed on the left end of the front sunshade curtain supporting long shaft 46; the front sunshade curtain rolling shaft sleeve 32 is sleeved on the outside of the front sunshade curtain spring drum 43 and the front sunshade curtain supporting roller 45, and the front sunshade curtain supporting roller 45 also serves as the internal intermediate support and rotating roller of the front sunshade curtain rolling shaft sleeve 32.

[0082] Since the left end of the front sunshade curtain retractor 33 is combined with the front sunshade curtain spring drum 43 and the right end is combined with the front sunshade curtain right spiral end 42, the front sunshade curtain retractor 33 converts the deformation of the spring into elastic potential energy during the closing process of the front sunshade curtain 4. During the opening process of the front sunshade curtain 4, the elastic potential energy is automatically released to drive the spring to retract, thereby driving the front sunshade curtain reel sleeve 32 and the front sunshade curtain 4 to retract and open.

[0083] like Fig.10 and Fig.11As shown, the front sunshade curtain retractor 33 and the rear sunshade curtain retractor 31 of this embodiment are similar to spring structures.

[0084] Further, such as Fig.19 As shown, the front sunshade spring drum 43 has a circular hole in the middle, and the head of the front sunshade spring drum 43 is connected to the front sunshade retractor 33, and a spiral groove is provided in the circumferential direction of the connecting section with the head. During the stretching process, the inner diameter of the front sunshade retractor 33 decreases until it is clamped with the front sunshade spring drum 43, and then drives the left spiral end 47 of the front sunshade to rotate. Fig.21 The front sunshade short coil spring 48 is connected as shown, which will drive the front sunshade short coil spring 48 to rotate; by setting the stall torque of the front sunshade motor 12 and the rotation torque of the front sunshade short coil spring 48 to achieve a balance, it can ensure that the sunshade is closed and sealed tightly, and can avoid the front sunshade motor 12 from rotating beyond the stroke, causing the front sunshade retractor 33 to be over-stretched and irreversible.

[0085] like Fig.23 The front sunshade curtain support short shaft 49 shown is a common support shaft for the front sunshade curtain spring drum 43, the front sunshade curtain short coil spring 48, the front sunshade curtain reel sleeve 32, and the front sunshade curtain retractor 33; Fig. 22 The front sunshade curtain support long shaft 46 shown is a common support shaft for the front sunshade curtain right spiral end 42, the front sunshade curtain spring drum 43, the front sunshade curtain long spiral spring 44, the front sunshade curtain support roller 45, the front sunshade curtain reel sleeve 32, and the front sunshade curtain retractor 33. This embodiment can achieve better retracting and supporting effects by using the long shaft and short shaft in conjunction with the long spring and short spring structure.

[0086] In this embodiment, the front sunshade spring drum 43 is made of foam material and is used to wrap the sunshade spring drum 43. Fig. 20 The front sunshade curtain long coil spring 44 shown in the figure, the front sunshade curtain winding sleeve 32 can rotate around the front sunshade curtain spring winding drum 43, and the front sunshade curtain long coil spring 44 can also rotate around the front sunshade curtain spring winding drum 43. Fig.18 The spiral groove at the right spiral end 42 of the front sunshade shown rotates; the front sunshade spring drum 43 can support the front sunshade winding shaft sleeve 32, and can also avoid direct contact and friction between the front sunshade long spiral spring 44 and the front sunshade winding shaft sleeve 32. The foam noodle material can also absorb the noise caused by the rotation.

[0087] The retracting mechanism of the rear sunshade curtain 5 includes a rear sunshade curtain retractor 31, a rear sunshade curtain reel sleeve 30, a rear sunshade curtain short coil spring 40, a rear sunshade curtain long coil spring 36, a rear sunshade curtain spring reel 35, a rear sunshade curtain support long shaft 38, a rear sunshade curtain support roller 37, a rear sunshade curtain support short shaft 41, and a rear sunshade curtain support roller 38. Fig.16 The left spiral end 34 of the rear sunshade curtain shown in FIG. Fig.17The rear sunshade curtain right spiral end 39 shown has the same structure as the front sunshade curtain retracting mechanism, which will not be described in detail here.

[0088] This embodiment adopts a double sunshade structure of a front sunshade 4 and a rear sunshade 5, which can reduce the diameter of the reel of a single sunshade, and the reel structure is arranged at the junction of the two sunshades, does not occupy the head space of the front row or the second row, and does not affect the field of vision of the driver and passengers. The front sunshade 4 and the rear sunshade 5 are respectively equipped with motors, and the two sunshades can be opened at the same time, or the sunshades of the front row or the rear row can be opened separately, meeting the different needs of the front and rear row drivers and passengers.

[0089] The dual motors of this embodiment are both arranged at the front end, which simplifies the rear end structure of the sunshade without affecting the field of vision of the front passengers, and there is no need to make more structures; and the pull rope mechanism is all built into the guide rail, so the rear end structure of the sunshade can be made thinner in the Z direction, thereby increasing the head space for the rear passengers. At the same time, the rear end structure can be made shorter in the X direction, which can increase the X-direction light transmittance of the sunshade and allow the rear passengers to have a larger light transmittance area.

[0090] Embodiment 2:

[0091] The present embodiment provides a control method for an electric double sunshade system, which adopts the electric double sunshade system described in Example 1. The electric double sunshade system switches between four working states, namely, fully open, fully closed, front open and then closed, and front closed and then open, through the voice of the front driver or passenger, large screen instructions, and button instructions from the rear passenger on the auxiliary instrument.

[0092] The specific control process is:

[0093] (1) In the first working state, the front sunshade 4 and the rear sunshade 5 are rolled up at the same time (fully opened):

[0094] like Figure 24-26 As shown, the front sunshade curtain motor 12 rotates clockwise and the rear sunshade curtain motor 13 rotates counterclockwise, and the transmission gear of the front sunshade curtain motor 12 drives the left pull cord 14 of the front sunshade curtain to move leftward and backward, and at the same time, the right pull cord 16 of the front sunshade curtain moves rightward and backward, thereby driving the front sunshade curtain 4 to move backward and retract to an open state; the transmission gear of the rear sunshade curtain motor 13 drives the left pull cord 15 of the rear sunshade curtain to move rightward and forward, and at the same time, the right pull cord 17 of the rear sunshade curtain moves leftward and forward, thereby driving the rear sunshade curtain 5 to move forward and retract to an open state.

[0095] (2) In the second working state, the front sunshade 4 and the rear sunshade 5 are simultaneously maintained in unfolding (fully closed):

[0096] like Fig. 27As shown, the front sunshade curtain motor 12 and the rear sunshade curtain motor 13 keep the front sunshade curtain 4 and the rear sunshade curtain 5 unfolded to cover the panoramic glass through corresponding pull ropes.

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

[0098] like Figure 28-Figure 30 As shown, the front sunshade curtain motor 12 rotates clockwise, and the transmission gear of the front sunshade curtain motor 12 drives the left pull cord 14 of the front sunshade curtain to move leftward and backward, and at the same time drives the right pull cord 16 of the front sunshade curtain to move rightward and backward, thereby driving the front sunshade curtain 4 to move backward and retract to an open state; the rear sunshade curtain motor 13 prevents the rear sunshade curtain 5 from being retracted and maintains the unfolded (closed) state.

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

[0100] like Figure 31-Figure 33 As shown, the rear sunshade curtain motor 13 rotates counterclockwise, and the transmission gear of the rear sunshade curtain motor 13 drives the rear sunshade curtain left pull rope 15 to move rightward and forward, and drives the rear sunshade curtain right pull rope 17 to move leftward and forward, thereby driving the rear sunshade curtain 5 to move forward and retract to the open state. The front sunshade curtain motor 12 keeps the front sunshade curtain 4 from retracting and maintains the unfolded (closed) state.

[0101] This embodiment can meet the different needs of front and rear passengers by switching the above four working states.
