Description

Technical Field

[0001] The present invention relates to the technical field of an electric drive device for the linked deployment and retraction of a side window sunshade and a corner window sunshade for a motor vehicle. Background Art

[0002] The electric sunshade structure currently applied to motor vehicles is generally like the blind arrangement for motor vehicle in US 2008 / 0179024 A1, which includes a light-shielding curtain that can be wound and retracted by a curtain winding shaft group. Both ends of the movable side rod on one side of the light-shielding curtain are connected to a motor group through a flexible transmission element. The motor group drives the displacement of the movable side rod of the light-shielding curtain through the flexible transmission element, and with the automatic winding force of the curtain winding shaft group on the light-shielding curtain, the light-shielding curtain can be deployed and retracted.

[0003] Although the aforementioned electric light-shielding device provides a device that can drive the light-shielding curtain to deploy and retract in an electric manner, however, the aforementioned electric light-shielding device can only drive a single light-shielding curtain. In the body of a current motor vehicle, the side window on the side is usually designed to be a liftable and closable side window and a triangular window in a fixed state behind the side window according to the shape of the vehicle body. To provide an appropriate sunshade function for the side window and the triangular window behind it, a side window sunshade is installed at the side window, and a corner window sunshade is installed at the triangular window behind the side window. If the aforementioned existing electric light-shielding device is used, both the side window sunshade and the corner window sunshade need to be independently driven light-shielding devices, which have problems such as a complex overall mechanism and high cost.

[0004] In order to simplify the electric drive mechanism of both the side window sunshade and the corner window sunshade, someone proposed a "side sunshade device for motor vehicles" as disclosed in CN112829552 B of China, which includes a main curtain, a secondary curtain and a drive system. The main curtain is connected to a rotatable winding shaft arranged horizontally, and a pull-out profile is arranged on one side of the main curtain's pulling-out direction. When the main curtain is unfolded and folded, the two ends of the pull-out profile move straight up and down along the first guide track and the second guide track fixed to the vehicle, so that the main curtain can be unfolded upward and folded downward. The secondary curtain is located at the rear side of the main curtain and is connected to a rotatable winding shaft arranged longitudinally. The secondary curtain can be pulled out and unfolded horizontally, which is different from the pulling-out direction of the main curtain when it is pulled out and unfolded upward, and the main curtain and the secondary curtain have different pulling-out lengths. A lever element is arranged on one side of the secondary curtain's pulling-out direction, and the lever element is connected to a longitudinally movable connecting rod, which is installed in a transversely arranged third guide rail and can move along the third guide rail. The drive system comprises a flexible drive transmission and an electric drive motor, the flexible drive transmission extends longitudinally and is placed in the region of the first, second and third guide rails, the flexible drive transmission is driven by a specific electric drive motor, the drive transmission is formed by at least one cable pulling system, the cable pulling system has at least one pulling cable that can be fully tensioned, the cable pulling system comprises two cable drums and a carrier, each cable drum is assigned to a first and a second cable pulling member of the first guide rail and the second guide rail of the main curtain, the second cable pulling member of the second guide rail of the main curtain is further deflected along the third guide rail of the secondary curtain, the carrier is assigned to the second cable pulling member, the carrier carries or releases the lever element of the secondary curtain according to the position of the second cable pulling member. Thus, the electric drive motor of the drive system drives the pulling cable of the flexible drive transmission to drive the pull-out profile of the main curtain and the lever element of the secondary curtain to move, so that the main curtain and the secondary curtain are unfolded and retracted. The carrier is assigned to the second cable pulling member, and the carrier carries or releases the lever element of the secondary curtain according to the position of the second cable pulling member, thereby delaying the time point of driving the secondary curtain to unfold.

[0005] Although the aforementioned existing "light-shielding device for the side of a motor vehicle" can drive the main curtain and the secondary curtain to unfold and retract with a single set of drive systems, overcoming the problems of the overall complex mechanism and high cost that both the aforementioned side window sunshade curtain and the corner window sunshade curtain need to be independently driven. However, the arrangement of the pulling cables in its flexible drive transmission device is configured in a full-loop winding manner by combining multiple cable drums. When the electric drive motor of the drive system drives the pulling cables of the flexible drive transmission device to drive the pulling profile of the main curtain and the lever element of the secondary curtain to move, based on the full-loop winding configuration of the pulling cables, the pulling cables must be pulled and released to drive the pulling profile and the lever element of the secondary curtain to move. Therefore, during the operation process, it is not easy to maintain a stable transmission performance, and the pulling cables must be kept in a fully tensioned state. Therefore, at least one cable tensioning device must be configured in the drive system to maintain the tension of the pulling cables, and thus resistance is generated to the pulling cables. Therefore, the design of the aforementioned existing "light-shielding device for the side of a motor vehicle" still has problems such as a complex overall structure and poor transmission performance. Summary of the Invention

[0006] The technical problem to be solved by the present invention is: to provide a semi-loop cable-pulling type electric drive device for a side window sunshade curtain and a corner window sunshade curtain, and solve the problems of complex structure and poor transmission performance of the existing electric drive devices for side window sunshade curtains and corner window sunshade curtains.

[0007] The technical solution proposed by the present invention is: to provide a semi-loop cable-pulling type electric drive device for the linkage of a side window curtain and a corner window curtain, which can connect the side window sunshade curtain located at the side window of a motor vehicle and the corner window sunshade curtain located at the triangular window behind the side window. The semi-loop cable-pulling type electric drive device includes: a guide rail group, which includes a front longitudinal guide rail located in front of the side window and a rear longitudinal guide rail located between the side window and the triangular window. Both ends of the movable side plates of the side window curtain of the side window sunshade curtain can move up and down along the front longitudinal guide rail and the rear longitudinal guide rail respectively;

[0008] an electric drive mechanism, which includes an electric motor and a transmission component connected to the electric motor; and

[0009] Half-loop cable driving mechanism, which connects the electric driving mechanism, the movable side plate of the side window curtain of the side window sunshade curtain, and the movable side plate of the corner window curtain of the corner window sunshade curtain. The half-loop cable driving mechanism includes a cable reel, a pusher, and a cable. The cable reel is connected to the transmission component. The pusher can drive the movable side plate of the corner window curtain in a clutchable manner. One end of the cable is connected to the cable reel, and the other end of the cable is a fixed end and is fixed to a fixed point above. The cable extends from the cable reel in a tensioned state, bypasses both ends of the movable side plate, and is connected to the pusher, forming a half-loop configuration. The electric driving mechanism drives the movable side plate and the pusher through the cable, and there is a time difference between the time point when the cable drives the movable side plate and the time point when the cable drives the movable side plate through the pusher, so as to delay the driving of the corner window curtain to unfold.

[0010] In the half-loop cable-driven electric driving device with the side window curtain and the corner window curtain linked as described above, the movable side plate of the corner window curtain can be operated to move up and down. The front end of the movable side plate has a side plate slider that can move along the rear longitudinal guide rail. The pusher is located inside the rear longitudinal guide rail and can push the movable side plate from below the side plate slider.

[0011] In the half-loop cable-driven electric driving device with the side window curtain and the corner window curtain linked as described above, the electric driving mechanism is located below the longitudinal guide rail. The cable extends from the cable reel in a tensioned state, passes through the rear longitudinal guide rail from below the rear longitudinal guide rail, then bypasses the upper end of the rear longitudinal guide rail and turns downward to connect to the pusher below the side plate slider at the front end of the movable side plate, then bypasses the lower part of the rear longitudinal guide rail and turns forward, then bypasses the lower part of the front longitudinal guide rail and turns upward to pass through the front longitudinal guide rail and bypasses the upper end of the front longitudinal guide rail and turns downward, then continues to bypass the side plate sliders at the front end and the rear end of the movable side plate and turns upward, and the fixed end of the cable is fixed above the rear longitudinal guide rail. The driven cable can be operated to push the side plate slider at the front end of the movable side plate upward and can move downward to disengage from the side plate slider.

[0012] In the half-loop cable-driven electric driving device with the side window curtain and the corner window curtain linked as described above, an upper pulley is installed at the upper end of each of the front longitudinal guide rail and the rear longitudinal guide rail, a lower pulley is provided at the lower part of each of the front longitudinal guide rail and the rear longitudinal guide rail, and a movable pulley is installed on the side plate slider at the front end of the movable side plate and the side plate slider at the rear end of the movable side plate. The cable bypasses the upper pulleys, the lower pulleys, and the movable pulleys.

[0013] In the semi-loop cable-pulling type electric drive device with the side window curtain and the corner window curtain being linked as described above, the movable side plate of the corner window curtain can be operated to move back and forth. The movable side plate of the corner window curtain is combined with a rocker arm, and the lower end of the rocker arm is combined with a side plate slider. The side plate slider can move back and forth along a transverse guide rail. The pusher is located within the transverse guide rail and can push the side plate slider from the front of the side plate slider to drive the movable side plate.

[0014] In the semi-loop cable-pulling type electric drive device with the side window curtain and the corner window curtain being linked as described above, the electric drive mechanism is located below the longitudinal guide rail. The cable extends from the cable reel in a tensioned state, bypasses the rear end of the transverse guide rail and turns into the transverse guide rail, passes through and is connected to the pusher in front of the side plate slider at the lower end of the rocker arm, then turns from the front of the transverse guide rail and passes under the rear longitudinal guide rail through the rear longitudinal guide rail, then bypasses the upper end of the rear longitudinal guide rail and turns downward, then successively bypasses the side plate sliders at the rear end and the front end of the movable side plate and turns upward to pass through the front longitudinal guide rail, and the fixed end of the cable is fixed above the front longitudinal guide rail. The driven cable can be operated to push the side plate slider provided at the bottom end of the rocker arm backward and move forward to disengage from the side plate slider.

[0015] In the semi-loop cable-pulling type electric drive device with the side window curtain and the corner window curtain being linked as described above, movable pulleys are installed on the side plate sliders at the front end and the rear end of the movable side plate. An upper pulley is installed at the upper end of the rear longitudinal guide rail, a lower pulley is installed below the rear longitudinal guide rail, a rear turning pulley is installed at the rear end of the transverse guide rail, and a front turning pulley is provided in front of the lower pulley below the rear longitudinal guide rail. The cable bypasses the upper pulley, the lower pulley, the movable pulleys, the rear turning pulley and the front turning pulley.

[0016] The beneficial effects that can be achieved by the present invention are at least as follows:

[0017] 1. Through the cable winding and transmission structure in the semi-loop cable-driven mechanism and the electric drive mechanism, a single set of simplified mechanism can drive the cable to drive the side window curtain and the corner window curtain to unfold and retract.

[0018] 2. The time point when the cable drives the movable side plate of the side window curtain has a time difference relative to the time point when the cable drives the movable side plate of the corner window curtain via the pusher, delaying the driving of the corner window curtain to unfold, so as to reconcile the unequal unfolding strokes of the side window curtain and the corner window curtain.

[0019] 3. In the semi-loop cable drive type, one end of the cable in the cable drive mechanism is connected to the cable reel through a semi-loop cable, and the other end of the cable is fixed to a fixed point above. This allows the cable reel to directly wind up the cable, driving the side window curtain and the corner window curtain to unfold. When the cable reel releases the cable, the side window curtain is automatically wound up by the side window curtain winding shaft group, and the corner window curtain is automatically wound up by the corner window curtain winding shaft group, ensuring smooth unfolding and retracting movements of the side window curtain and the corner window curtain.

The movable side plate 201 is pivotally connected to a rocker arm 202, and the lower end of the rocker arm 202 can move along the horizontal guide rail 22, so that the corner window curtain 20 can be unfolded backward and folded forward.

[0068] As Figure 1 、 Figure 2 and Figure 7 shown in the embodiments, the semi-loop cable-driven electric drive device 3 is installed inside the vehicle door, and the semi-loop cable-driven electric drive device 3 can drive the movable side plate 101 of the side window curtain 10 to move up and down, and can drive the movable side plate 201 of the corner window curtain 20 to move up and down or back and forth in a clutchable manner.

[0069] As Figure 1 、 Figure 2 and Figure 7 shown, the semi-loop cable-driven electric drive device 3 can be directly installed on the vehicle door, or the semi-loop cable-driven electric drive device 3 is combined with a base frame 3A and is set on the vehicle door through the base frame. The semi-loop cable-driven electric drive device 3 can be realized by at least the following several embodiments. Basically, the semi-loop cable-driven electric drive device 3 includes a guide rail group 30, an electric drive mechanism 40, and a semi-loop cable driving mechanism 50. Among them:

[0070] As Figure 1 、 Figure 7As shown, the guide rail group 30 includes a front longitudinal guide rail 31 and a rear longitudinal guide rail 32. The front longitudinal guide rail 31 is located at the front side of the side window, and the rear longitudinal guide rail 32 is located between the side window and the triangular window. Both ends of the movable side plate 101 of the side window curtain 10 are each provided with a side plate slider 33. The side plate sliders 33 at both ends of the movable side plate 101 can respectively move up and down along the front longitudinal guide rail 31 and the rear longitudinal guide rail 32, so that the side window curtain 10 can be unfolded and retracted. The movable edge plate 201 of the corner window curtain 20 is directly or indirectly combined with a side plate slider 34, and the corner window curtain 20 is driven to be unfolded and retracted by operating the side plate slider 34. Among them, the front end of the movable edge plate 201 is directly combined with a said side plate slider 34, and moves up and down along the rear longitudinal guide rail 32 by operating the side plate slider 34; alternatively, the rocker arm 202 pivotally connecting the movable edge plate 201 is connected to a said side plate slider 34 located in the transverse guide rail 22, and moves back and forth along the transverse guide rail 22 by operating the side plate slider 34.

[0071] As Figure 1 , Figure 2 and Figure 7 shown, the electric drive mechanism 40 is provided in the vehicle door and includes a motor 41, a transmission assembly 42 and a housing 43. The motor 41 can be installed in the vehicle door, the transmission assembly 42 can be installed in the vehicle door and is connected to the motor 41, and the housing 43 is sleeved outside the motor 41 and the transmission assembly 42. In this embodiment, the electric drive mechanism 40 is located below the side window sunshade 1 and the corner window sunshade 2. Preferably, as Figure 4 shown, the electric drive mechanism 40 is located below the rear longitudinal guide rail 32. The transmission assembly 42 can be selected as a combination of a worm and a worm gear or a gear set. In this embodiment, the transmission assembly 42 is selected as a combination of a worm and a worm gear. The worm is connected to the motor 41, and the worm gear is pivotally installed in the housing 43 and meshes with the worm.

[0072] As Figure 1 , Figure 2 and Figure 7 shown, the half-loop cable driving mechanism 50 is provided in the vehicle door and is connected to the electric drive mechanism 40, the movable side plate 101 of the side window curtain 10 and the movable edge plate 201 of the corner window curtain 20, so that the electric drive mechanism 40 can drive the movable side plate 101 of the side window curtain 10 and the movable edge plate 201 of the corner window curtain 20 to displace via the half-loop cable driving mechanism 50, and drive the side window curtain 10 and the corner window curtain 20 to be unfolded and retracted. As Figures 1 to 5 and Figures 7 to 8 shown, the half-loop cable driving mechanism 50 includes a cable reel 51, a pushing member 52 and a cable 53, wherein:

[0073] As Figures 1 to 5 and Figures 7 to 8As shown, the wire reel 51 is connected to the transmission assembly 42 of the electric drive mechanism 40 and can be driven to rotate forward and backward. In this embodiment, the wire reel 51 is pivotally arranged in the housing 43 of the electric drive mechanism 40 and can be driven to rotate by the transmission assembly 42. Among them, the wire reel 51 can be directly coaxially connected to the worm wheel of the electric drive mechanism 40, or the wire reel 51 is combined with a gear set to connect to the worm wheel. The gear set includes a first gear and a second gear. The first gear is coaxially connected to the worm wheel, the second gear is coaxially connected to the wire reel 51, and the first gear meshes with the second gear.

[0074] As Figures 1 to 2 , Figure 5 , Figures 7 to 8 shown, the pusher 52 can drive the side plate slider 34 of the corner window curtain 20 in a clutchable manner. The pusher 52 can be realized at least in accordance with the two embodiments disclosed according to the different unfolding and folding states of the corner window curtain 20. Among them: Figure 1 and Figure 7 disclosed.

[0075] As Figures 1 to 2 , Figure 5 shown in the embodiment, when the movable side plate 201 of the corner window curtain 20 moves up and down, the pusher 52 is arranged in the rear longitudinal guide rail 32 and is located below the side plate slider 34 at the front end of the movable side plate 201. The pusher 52 can be operated to push the side plate slider 34 at the front end of the movable side plate 201 upward and can move downward to disengage from the side plate slider 34.

[0076] As Figures 7 to 8 shown in the embodiment, when the movable side plate 201 of the corner window curtain 20 can move back and forth, the pusher 52 is arranged in the transverse guide rail 22 of the corner window sunshade 2 and is located in front of the side plate slider 34 at the lower end of the rocker arm 202. The pusher 52 can be operated to push the side plate slider 34 arranged at the bottom end of the rocker arm 202 backward and can move forward to disengage from the side plate slider 34.

[0077] As Figure 1 , Figure 2 , Figure 5 and Figure 7As shown, the two ends of the wire rope 53 are respectively a connection end and a fixed end 531. The connection end of the wire rope 53 is connected to the wire winding wheel 51, and the fixed end 531 is fixed to a fixed point at the upper position. The wire rope 53 extends from the wire winding wheel 51 in a tensioned state, bypasses both ends of the movable side plate 101, and is connected to the push member 52, forming a semi-loop shape. The electric drive mechanism 40 drives the movable side plate 101 and the push member 52 through the wire rope 53, and can drive the side plate slider 34 of the corner window curtain 20 in a clutchable manner through the push member 52, so that the time point when the wire rope 53 drives the movable side plate 101 has a time difference relative to the time point when the wire rope 53 drives the movable side plate 201 through the push member 52, and the action of driving the corner window curtain 20 to unfold can be delayed to reconcile the state where the movement stroke of the side window curtain 10 unfolding is not equal to the movement stroke of the corner window curtain 20 unfolding.

[0078] In order to match the movement mode of the movable side plate 201 in the unfolding and retracting direction of the corner window curtain 20, the installation method of the wire rope 53 forming a semi-loop shape can be realized by the following embodiments, where:

[0079] As Figures 1 to 6 shown, in the embodiment where the movable side plate 201 of the corner window curtain 20 can move up and down, the wire rope 53 extends from the wire winding wheel 51 in a tensioned state, passes under the rear longitudinal guide rail 32 from below the rear longitudinal guide rail 32, then turns downward after passing around the upper end of the rear longitudinal guide rail 32. The wire rope 53 is connected to the push member 52 below the side plate slider 34 at the front end of the movable side plate 201, then turns forward after passing around the lower part of the rear longitudinal guide rail 32, turns upward after passing around the lower part of the front longitudinal guide rail 31, passes through the front longitudinal guide rail 31, turns downward after passing around the upper end of the front longitudinal guide rail 31, then continues to pass around the side plate slider 33 at the front end of the movable side plate 101 and the side plate slider 33 at the rear end of the movable side plate 101 and turns upward, and the fixed end 531 of the wire rope 53 is fixed at a fixed position above the rear longitudinal guide rail 32. In this way, the driven wire rope 53 can be operated to push the side plate slider 34 at the front end of the movable side plate 201 upward and can move downward to disengage from the side plate slider 34.

[0080] As Figures 1 to 6 shown, in the foregoing embodiment, in order to improve the smoothness of the movement of the wire rope 53 when it is operated, an upper pulley 311, 321 is installed at the upper end of the front longitudinal guide rail 31 and the upper end of the rear longitudinal guide rail 32 respectively, a lower pulley 312, 322 is provided below the front longitudinal guide rail 31 and the rear longitudinal guide rail 32 respectively, and a movable pulley 331 is installed on both the side plate slider 33 at the front end of the movable side plate 101 and the side plate slider 33 at the rear end of the movable side plate 101. The wire rope 53 bypasses the upper pulleys 311, 321, the lower pulleys 312, 322 and the movable pulley 331.

[0081] As Figures 1 to 2As shown, after the cable 53 turns from the lower pulley 322 below the rear longitudinal guide 32 and extends forward, it can bypass the lower pulley 2 below the front longitudinal guide 31 and then turn into the front longitudinal guide 31. Or, as Figure 3 shown, when a rotary guide 111 is provided at the front end of the side window curtain winding shaft group 11, a front turning pulley 35 can be additionally provided in front of the rotary guide 111 relative to the lower part of the front longitudinal guide 31. After the cable 53 turns from below the rear longitudinal guide 32 and extends forward, it bypasses the front turning pulley 35 and the lower pulley 2 below the front longitudinal guide 31 and then turns into the front longitudinal guide 31.

[0082] As Figures 7 to 9 shown, in the embodiment where the movable side plate 201 of the corner window curtain 20 can move back and forth, the cable 53 extends from the cable reel 51 in a tensioned state, turns backward around the rear end of the transverse guide 22 and enters the transverse guide 22, passes through and is connected to a pusher 52 in front of the side plate slider 34 at the lower end of the rocker arm 202. Then it turns from the front of the transverse guide 22, passes under the rear longitudinal guide 32 through the rear longitudinal guide 32, then turns around the upper end of the rear longitudinal guide 32 and turns downward, continues to bypass the side plate slider 33 at the rear end of the movable side plate 101 and the side plate slider 33 at the front end of the movable side plate 101 and turns upward through the front longitudinal guide 31, and the fixed end 531 of the cable 53 is fixed at a fixed position above the front longitudinal guide 31. In this way, the driven cable 53 can be operated to push the side plate slider 34 provided at the bottom end of the rocker arm 202 backward and move forward to disengage from the side plate slider 34.

[0083] As Figures 7 to 9 shown, in the foregoing embodiment, in order to improve the smooth movement of the cable 53 during operation, a movable pulley 33 is installed on both the side plate slider 33 at the front end of the movable side plate 101 and the side plate slider 33 at the rear end of the movable side plate 101, an upper pulley 321 is installed at the upper end of the rear longitudinal guide 32, a lower pulley 322 is installed below the rear longitudinal guide 32, and a rear turning pulley 36 is installed at the rear end of the transverse guide 22. A front turning pulley 35 is provided in front of the lower pulley below the rear longitudinal guide 32. The cable 53 bypasses the upper pulley 321, the lower pulley 322, the movable pulley 33, the rear turning pulley 36 and the front turning pulley 35.

[0084] Regarding the operation of the semi-loop cable-driven electric drive device 3 of the side window sunshade 1 and the corner window sunshade 2 of the present invention to drive the side window sunshade 1 and the corner window sunshade 2, the description is as follows:

[0085] As Figures 1 to 6As shown, in the embodiment where the movable side plate 201 of the corner window curtain 20 can move up and down, when the motor 41 of the electric drive mechanism 40 is started to drive the wire reel 51 to rotate forward to wind up the wire rope 53, upward thrust is provided to the front and rear ends of the movable side plate 101 of the side window curtain 10 through the wire rope 53, so that the side window curtain 10 unfolds upward. On the other hand, while the wire reel 51 winds up the wire rope 53, after the pusher 52 is driven by the wire rope 53 to move upward by a predetermined stroke, the movable side plate 201 of the corner window curtain 20 is pushed to rise. The time point when the wire rope 53 drives the movable side plate 101 has a time difference relative to the time point when the wire rope 53 drives the movable side plate 201 via the pusher 52, and the action of driving the corner window curtain 20 to unfold is delayed until the side window curtain 10 and the corner window curtain 20 are fully unfolded, and then the motor 41 stops driving the wire reel 51 to wind up the wire rope 53.

[0086] As Figure 6 shown, when the motor 41 of the electric drive mechanism 40 drives the wire reel 51 to rotate reversely to release the wire rope 53, at the same time, the side window curtain 10 is automatically wound up and retracted by the side window curtain winding shaft group 11, and the corner window curtain 20 is automatically wound up and retracted by the corner window curtain winding shaft group 21. Among them, since the retraction stroke of the corner window curtain 20 is shorter than that of the side window curtain 10, when the corner window curtain 20 reaches full retraction, the motor 41 of the electric drive mechanism 40 still continues to drive the wire reel 51 to rotate reversely to release the wire rope 53 until the side window curtain 10 is retracted. The pusher 52 is driven by the wire rope 53 and disengages from the side plate slider 34 at the lower end of the rocker arm 202 connecting the movable side plate 201 of the corner window curtain 20.

[0087] As Figures 7 to 9 shown, in the embodiment where the movable side plate 201 of the corner window curtain 20 can move back and forth, when the motor 41 of the electric drive mechanism 40 is started to drive the wire reel 51 to rotate forward to wind up the wire rope 53, upward thrust is provided to the front and rear ends of the movable side plate 101 of the side window curtain 10 through the wire rope 53, so that the side window curtain 10 unfolds upward. On the other hand, while the wire reel 51 winds up the wire rope 53, after the pusher 52 is driven by the wire rope 53 to move backward by a predetermined stroke, the side plate slider 34 at the lower end of the rocker arm 202 connecting the movable side plate 201 of the corner window curtain 20 is pushed to move backward, so that the corner window curtain 20 unfolds backward. The time point when the wire rope 53 drives the movable side plate 101 has a time difference relative to the time point when the wire rope 53 drives the movable side plate 201 via the pusher 52, and the action of driving the corner window curtain 20 to unfold is delayed until the side window curtain 10 and the corner window curtain 20 are fully unfolded, and then the motor 41 stops driving the wire reel 51 to wind up the wire rope 53.

[0088] As Figure 9As shown in the figure, when the motor 41 of the electric drive mechanism 40 drives the wire reel 51 to rotate reversely to release the wire rope 53, at the same time, the side window curtain winding shaft group 11 automatically winds up and retracts the side window curtain 10, and the corner window curtain winding shaft group 21 automatically winds up and retracts the corner window curtain 20. Among them, since the retraction stroke of the corner window curtain 20 is shorter than that of the side window curtain 10, when the corner window curtain 20 reaches full retraction, the motor 41 of the electric drive mechanism 40 still continuously drives the wire reel 51 to rotate reversely to release the wire rope 53 until the side window curtain 10 is retracted. Driven by the wire rope 53, the pushing member 52 disengages from the side plate slider 34 at the lower end of the rocker 202 of the movable side plate 201 of the corner window curtain 20.
