In order to conform to the shape of the unequal front and rear ends of the side windows and provide a comfortable sunshade function, the curtain provided by the existing electric side window roller blinds must match the shape of the side windows with unequal front and rear ends, and the curtain of the electric side window roller blinds must be able to receive sufficient support after being unfolded. Therefore, the composition structure of the existing electric side window roller blinds mainly utilizes the motor of the electric drive mechanism to drive the flexible strip rocker arm to move back and forth along the guide rail, or utilizes the motor of the electric drive mechanism to drive the rack belt rocker arm through the gear set to move back and forth along the guide rail, and then drives the curtain connected to the curtain retractor to unfold and retract through the rocker arm.

[0003] In the aforementioned existing electric side window rolling curtain, the movable edge of the curtain is pivotally connected to the rocker arm, and the upper round rod and the lower round rod at the lower end of the rocker arm move along the upper rail groove and the lower rail groove of the guide rail respectively, and the lower rail groove at the lower position is inclined relative to the upper rail groove at the upper position, so that the driven rocker arm can swing and tilt backward and return to the front, so that the unfolded curtain can completely cover the side windows of different sizes at the front and rear ends; when the driven rocker arm drives the curtain to be retracted, the curtain can be retracted by the curtain retractor.

[0004] However, in the composition structure of the aforementioned existing electric side window roller blind, its rocker arm slides by contacting the upper rail groove and the lower rail groove of the guide rail at a single point with the upper round rod and the lower round rod arranged at intervals in the upper and lower ends of the rocker arm, making it difficult for the electric drive mechanism to provide a stable driving force to the rocker arm in the process of driving the rocker arm to move along the guide rail.

[0014] In the pull-wire electric side window roller blind as described above, the upper rail groove and the lower rail groove are both parallel to the moving path.

[0015] In the pull-wire electric side window roller blind as described above, the pulley body is provided with a movable groove which passes through from top to bottom between the two roller groups, and the connecting end of the rocker arm can be movably inserted into the movable groove. The connecting end has a pivot and is connected to the pulley body through the pivot. The rocker arm has a center vertical line passing through the center of the pivot, and the position where the end of the rocker arm contacts the transverse guide rail is biased to the side of the center vertical line facing the curtain retractor.

[0016] In the pull-wire electric side window roller blind as described above, the end of the rocker arm has an end wheel set, and the end of the rocker arm can rollably contact the bottom surface of the lower rail groove of the transverse guide rail through the end wheel set.

[0019] In the pull-wire type electric side window roller blind as described above, the pull-wire guide includes a base, a first wire pulley, a second wire pulley, an intermediate wire pulley and an elastic force supply element. The first wire pulley and the second wire pulley are pivotally arranged in the base at intervals. The first wire pulley is adjacent to the transverse guide rail. The intermediate wire pulley is pivotally arranged in the base so as to be displaceable and is located between the first wire pulley and the second wire pulley. The pull wire passing through the transverse guide rail bypasses the first wire pulley, the intermediate wire pulley and the second wire pulley, and then is wrapped around the pull-wire driving wheel. The elastic force supply element is connected to the intermediate wire pulley, and the intermediate wire pulley pushes the pull wire through the elastic force of the elastic force supply element.

[0020] The beneficial effects that the pull-wire electric side window roller blind of the present invention can achieve are:

[0021] 1. Construct a good power circuit: the rocker transmission mechanism is installed in the transverse guide rail and can move laterally along the moving path, the lower end of the rocker connected to the movable edge of the curtain extends into the transverse guide rail, the rocker movable group is arranged in the rocker transmission mechanism and can swing, and the rocker transmission mechanism is connected to the pull wire of the electric drive mechanism, so that a good power circuit is formed between the curtain, the curtain retractor, the rocker, the rocker transmission mechanism and the pull wire.

[0022] 2. Keep the curtain in a good and stable tension state: During the process of unfolding and retracting the curtain, the electric drive mechanism drives the rocker transmission mechanism of the rocker arm to move along the transverse guide rail through the pull wire. When the rocker transmission mechanism moves on the transverse slide rail, it provides a stable bearing force to the rocker arm, and combines the power circuit formed by the curtain, curtain retractor, rocker arm, rocker transmission mechanism and pull wire, so that the force applied to the curtain by the electric drive mechanism through the pull wire, rocker transmission mechanism and rocker arm, and the force applied to the curtain by the curtain retractor can achieve a better balance, so that the tension acting on the curtain is maintained in a good and stable force state. In this way, the electric drive mechanism can smoothly drive the rocker arm to perform the unfolding and retracting actions of the curtain through the pull wire and the rocker transmission mechanism.

[0023] The pull-wire electric side window roller blind of the present invention can further roll and contact the transverse slide rail through the pulley of the rocker transmission mechanism, and the front and rear roller groups are located in the direction of the moving path of the rocker arm. The pulley provides a stable bearing force for the rocker arm that can swing forward and backward at the front and rear positions of the moving path, so that a good balance can be obtained between the force applied to the curtain by the electric drive mechanism through the pull wire, the pulley of the rocker transmission mechanism and the rocker arm, and the force applied to the curtain by the curtain retractor, so that the tension acting on the curtain is maintained in a stable state, and the electric drive mechanism can smoothly drive the rocker arm to perform the unfolding and retracting actions of the curtain through the pull wire and the pulley of the rocker transmission mechanism.

[0024] The pull-wire electric side window roller blind of the present invention can further utilize the transverse guide rail having an upper rail groove and a lower rail groove arranged vertically and connected to each other, and the pulley is installed in the upper rail groove. The two roller groups of the pulley are respectively installed at the two ends of the pulley body along the moving path direction. The two roller groups can rollably contact the bottom surface of the groove of the upper rail groove of the transverse guide rail, and the two ends of the pull wire are respectively connected to the two ends of the pulley body along the moving path direction, so that the electric drive mechanism can pull the pulley in both directions to move smoothly through the pull wire.

[0025] The pull-wire electric side window roller blind of the present invention can further utilize the pulley body to set an upper and lower through-shaped movable groove between the two roller groups. The connecting end of the rocker arm can be movably inserted into the movable groove, and the pulley body and the connecting end are connected by a pivot. The swing range of the rocker arm is limited by the movable groove. At the same time, the movable groove of the pulley body is located at the position of the rocker arm on both sides relative to the moving path direction, thereby reducing the shaking of the rocker arm due to external force.

[0026] The pull-wire electric side window roller blind of the present invention can further utilize the end wheel set at the end of the rocker arm, through which the end of the rocker arm can rollably contact the bottom surface of the lower rail groove of the transverse guide rail, thereby reducing the friction resistance between the rocker arm and the transverse guide rail. In addition, the two roller sets can each have two rollers, and the two rollers of each roller set are located on both sides of the moving path relative to the pulley body; the end wheel set has two rollers, and the two rollers are respectively located on both sides of the end of the rocker arm relative to the moving path, so as to improve the stability of the pulley and the end of the rocker arm of the rocker arm connected to the pulley moving in the transverse guide rail.

[0027] In the pull-wire electric side window roller blind of the present invention, the rocker arm transmission mechanism may further include a pull-wire guide, which is arranged on the outer side of the end of the transverse guide rail away from the curtain retractor. The pull wire connected to the rocker arm transmission mechanism is passed through the outside of the transverse guide rail, wrapped around the pull-wire guide and then wrapped around the pull-wire driving wheel, so as to guide the pull wire to smoothly turn to the pull-wire driving wheel and maintain the tension of the pull wire, thereby ensuring that the driving force output by the electric driving mechanism can move the pulley smoothly by pulling the pull wire in both directions.

The curtain retractor 10 includes an outer tube 11, an inner tube 12 arranged in the outer tube 11, and a tension torsion spring 13 arranged inside the inner tube 12. One side of the outer tube 11 has a curtain groove. The curtain retractor 10 provides a torsional elastic force to the inner tube 12 through the tension torsion spring 13.

[0071] like Figure 1 and Figure 2 As shown, the shape of the curtain 20 matches the shape of the side window, one side of the curtain 20 passes through the curtain channel of the curtain retractor 10 and extends into the outer tube 11 and is connected to the inner tube 12. The tension torsion spring 13 provides a torsional elastic force to the inner tube 12, so that the inner tube 12 can automatically reel in and release the curtain 20. The curtain 20 has a movable edge 21 extending from one side of the curtain retractor 10.

[0072] like Figure 1 , Figure 2 and Figure 4 , Figure 5As shown, the transverse guide rail 30 can be installed below the side window, one end of the transverse guide rail 30 is adjacent to the lower end of the curtain retractor 10, and extends from the lower end of the curtain retractor 10 toward the rear side of the side window, and the transverse guide rail 30 provides a moving path 300 extending along the front-rear direction. In the embodiment disclosed in the drawings, the transverse guide rail 30 has an upper rail groove 31 and a lower rail groove 32, and the upper rail groove 31 is connected to the lower rail groove 32. Among them, the upper rail groove 31 is parallel to the moving path 300, and the upper rail groove 31 and the lower rail groove 32 are arranged in parallel up and down.

[0073] like Figure 1 , Figure 2 and Figure 4 As shown, the upper end of the rocker arm 40 is pivotally connected to the movable edge 21 of the curtain 20, and the lower end of the rocker arm 40 extends into the transverse guide rail 30. In this embodiment, the lower end of the rocker arm 40 has a connecting end 41, and the connecting end 41 extends into the transverse guide rail 30, and the rocker arm 40 can move along the moving path 300. The connecting end 41 has a rocker arm end 42, and the rocker arm end 42 can movably contact the transverse guide rail 30.

[0074] like Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, the connecting end 41 of the rocker arm 40 passes through the upper rail groove 31 of the transverse guide rail 30 and extends into the lower rail groove 32, and the rocker arm end 42 is located in the lower rail groove 32. The rocker arm end 42 has an end wheel set 43, and the rocker arm end 42 can rollably contact the bottom surface of the lower rail groove 32 of the transverse guide rail 30 through the end wheel set 43, thereby reducing the friction resistance between the rocker arm end 42 and the transverse guide rail 30.

[0075] like Figure 2 , Figure 4 and Figure 5 As shown, the rocker transmission mechanism 50 is arranged in the transverse guide rail 30 and can move along the transverse guide rail 30, and the rocker arm 40 movable group is arranged in the rocker transmission mechanism 50. In this embodiment, the rocker transmission mechanism 50 includes a pulley 51, which is installed in the transverse guide rail 30 and can move along the upper rail groove 31. The pulley 51 is provided with two roller groups 512 spaced apart along the direction of the moving path 300, and the two roller groups 512 can rollably contact the transverse guide rail 30. The connecting end 41 of the rocker arm 40 is pivotally arranged between the two roller groups 512 of the pulley 51, and the rocker arm end 42 of the connecting end 41 is located below the pulley 51, and the rocker arm end 42 can movably contact the transverse guide rail 30, and the rocker arm 40 can swing in the transverse guide rail 30.

[0076] At Figure 4 and Figure 5In the disclosed embodiment, the pulley 51 has a pulley body 511, and the two roller groups 512 are respectively installed at the two ends of the pulley body 511 along the direction of the moving path 300, and the two roller groups 512 can rollably contact the bottom surface of the upper rail groove 31 of the transverse guide rail 30. The pulley body 511 is provided with a movable groove 5111 that passes through the upper and lower parts between the two roller groups 512. The connecting end 41 of the rocker arm 40 can be movably inserted into the movable groove 5111. The connecting end 41 has a pivot 411, and is connected to the pulley body 511 by the pivot 411, so that the rocker arm 40 can swing in the pulley body 511.

[0077] like Figure 4 and Figure 5 In the disclosed embodiment, the rocker arm 40 has a center vertical line L passing through the center of the pivot 411, and the position where the rocker arm end 42 contacts the transverse guide rail 30 is located on the side of the center vertical line L facing the curtain retractor 10. When the curtain retractor 10 applies a pulling force to the curtain 20, the rocker arm 40 can be prevented from being excessively biased toward the direction of the curtain retractor 10, so that the curtain 20 can be maintained in a balanced tension state.

[0078] In the above, the two roller groups 512 each have two rollers, and the two rollers of each roller group 512 are located on both sides of the moving path 300 relative to the pulley body 511; the end wheel group 43 has two rollers, and the two rollers are respectively located on both sides of the rocker arm end 42 relative to the moving path 300, thereby improving the stability of the pulley 51 and the rocker arm end 42 of the rocker arm 40 connected to the pulley 51 in moving in the transverse guide rail 30.

[0079] The electric drive mechanism 60 can be installed below the side window of the motor vehicle, such as Figure 1 , Figure 2 and Figure 3 and Figure 6 As shown, the electric drive mechanism 60 includes a motor 61, a cable drive wheel 62 and a cable 63. The motor 61 can be connected to the power supply in the motor vehicle and can be controlled to start and stop. The cable drive wheel 62 is connected to the motor 61 and can be driven to rotate. The cable 63 is wound around the cable drive wheel 62. The cable 63 can extend into the transverse guide rail 30 and connect the pulley 51. The motor 61 drives the pulley 51 and the rocker arm 40 movably assembled on the pulley 51 to move along the moving path 300 through the cable drive wheel 62 and the cable 63, and drives the curtain 20 to unfold and retract through the rocker arm 40 in combination with the curtain retractor 10. The cable-type electric side window roller blind drives the rocker arm 40 to move along the moving path 300 of the transverse guide rail 30 through the cable 63 and the rocker arm transmission mechanism 50, and drives the curtain 20 to unfold and retract.

[0080] like Figure 2 and Figure 3 In the disclosed embodiment, the two ends of the pull wire 63 are respectively connected to the two ends of the pulley body 511 located in the direction of the moving path 300, so that a good power circuit is formed between the curtain 20, the curtain retractor 10, the rocker arm 40, the rocker arm transmission mechanism 50 and the pull wire 63. The electric drive mechanism 60 drives the two ends of the pull wire 63 to pull and release to drive the rocker arm transmission mechanism 50 to move back and forth smoothly along the transverse guide rail 30.

[0081] like Figure 4 and Figure 5 As shown, a wire guide 52 may be further provided on the outer side of one end of the transverse guide rail 30 away from the curtain retractor 10, and the wire 63 connected to the rocker arm transmission mechanism 50 is passed through the wire guide 52 outside the transverse guide rail 30 and then wound around the wire driving wheel 62, so as to guide the wire 63 to turn smoothly to the wire driving wheel 62 and maintain a moderate tension of the wire 63, so as to ensure that the driving force output by the electric driving mechanism 60 can pull the rocker arm transmission mechanism 50 to move smoothly in both directions through the wire 63.

[0082] At Figure 4 and Figure 5 In the disclosed embodiment, the wire guide 52 includes a base 521, a first wire wheel 522, a second wire wheel 523, an intermediate wire wheel 524 and an elastic force supply element 525. The first wire wheel 522 and the second wire wheel 523 are pivotally arranged in the base 521 at intervals. The first wire wheel 522 is adjacent to the transverse guide rail 30. The intermediate wire wheel 524 is pivotally arranged in the base 521 so as to be displaceable and located between the first wire wheel 522 and the second wire wheel 523. The wire pulling wire 63 passing through the transverse guide rail 30 bypasses the first wire wheel 522, the intermediate wire wheel 524 and the second wire wheel 523, and then is wrapped around the wire pulling driving wheel 62. The elastic force supply element 525 is connected to the intermediate wire wheel 524. The intermediate wire wheel 524 pushes the wire pulling wire 63 through the elastic force of the elastic force supply element 525 to maintain a moderate tension on the wire pulling wire 63.

[0083] like Figure 4 and Figure 5 As shown, in the above, a long hole 5211 is set on each side wall of the base 521, and the two ends of the core shaft of the intermediate wire wheel 524 are respectively extended into the long hole 5211 of the base 521, and the intermediate wire wheel 524 can limit and guide the moving direction through the long hole 5211.

[0084] When the pull-wire electric side window roller blind of the present invention is applied to the side window of a motor vehicle, Figure 1 , Figure 2 and Figure 7As shown, the curtain 20 can be rolled up by the curtain retractor 10, the rocker arm 40 connected to the movable edge 21 of the curtain 20 and the pulley 51 of the rocker arm transmission mechanism 50 connected to the lower end of the rocker arm 40 are adjacent to the curtain retractor 10, and the curtain 20 is in a folded state.

[0085] like Figure 1 , Figure 2 and Figure 7 As shown, when the curtain 20 changes from the folded state to the unfolded state, the motor 61 of the electric drive mechanism 60 is started to drive the wire driving wheel 62 to rotate forward, and the wire driving wheel 62 exerts a pulling and releasing effect on the two ends of the wire 63, so that the wire 63 exerts a pulling force on the pulley 51 of the rocker transmission mechanism 50 toward the rear side of the side window, and then drives the rocker 40 to move backward along the transverse guide rail 30 through the pulley 51, and at the same time, the curtain 20 is pulled and unfolded by the rocker 40 and then stops. In the process of the curtain 20 being pulled and unfolded, the rocker 40 pivotally mounted on the pulley 51 of the rocker transmission mechanism 50 can swing to a tilted position within a limited range, so that the rocker 40 has enough tension to pull the curtain 20 to fully unfold and cover the side window. The rocker arm end 42 of the rocker arm 40 abuts against the bottom surface of the lower rail groove 32 of the transverse guide rail 30, and the position where the rocker arm end 42 contacts the transverse guide rail 30 is located on the side of the center vertical line L facing the curtain retractor 10. Therefore, when the curtain retractor 10 applies a pulling force to the curtain 20, the curtain 20 can maintain a balanced tension state.

[0086] like Figure 1 , Figure 2 and Figure 7 As shown, when the curtain 20 changes from the unfolded state to the folded state, the motor 61 of the electric drive mechanism 60 is started to drive the cable driving wheel 62 to rotate in the opposite direction, and the cable driving wheel 62 produces a release and a pull effect on the two ends of the cable 63, so that the cable 63 exerts a pulling force on the pulley 51 of the rocker transmission mechanism 50 toward the front direction of the side window, and then the pulley 51 of the rocker transmission mechanism 50 drives the rocker 40 to move forward along the transverse guide rail 30, and the curtain retractor 10 automatically retracts the curtain 20, so that the curtain 20 is retracted into the curtain retractor 10. In the process of the curtain 20 being pulled and retracted, the rocker 40 pivoted on the pulley 51 of the rocker transmission mechanism 50 can swing within a limited range to a side position close to the curtain retractor 10.

[0087] The above description is only an embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as above by the embodiment, it is not used to limit the present invention. Any technician in the field can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical contents disclosed above without departing from the scope of the technical solution of the present invention.
