BACKGROUND

[0002] At present, the window of motor vehicle side door is usually designed as side window and corner window, which can be lifted to open and close. In order to provide appropriate sunshade function for side window and corner window, side window curtain is installed on side window, and corner window curtain is installed on corner window behind side window. The electric curtain device installed on the window in the past has a curtain that can be wound around the winding shaft group. The edges of the curtain on one side are connected to the motor group through flexible transmission elements. The motor group drives the edges of the curtain to move through flexible transmission elements, and the automatic winding force of the winding shaft group on the curtain makes the curtain unfold and fold. Therefore, the side window curtain and the corner window curtain both need to use independent electric drive mechanisms to drive. Overall, the combination structure has the problems of complex mechanism and high cost.

[0003] In order to simplify and integrate the electric drive mechanisms of side window curtain and corner window curtain, CN112829552B patent case discloses "light shielding device for side window of motor vehicle", which includes main sheet (side window curtain), secondary sheet (corner window curtain) and drive system. The main sheet is connected to the horizontally arranged rotatable winding shaft, and the pull-out profile (movable side plate of side window curtain) is arranged on one side of the main sheet in the pull-out direction. In the case of unfolding and folding of the main sheet, the two ends of the pull-out profile move up and down along the first guide rail and the second guide rail fixed in the motorcycle, so that the main sheet can be unfolded upward and folded downward. The secondary sheet is located behind the main sheet and is connected to the longitudinally arranged rotatable winding shaft. The secondary sheet can be pulled out horizontally, and the pull-out direction of the secondary sheet is different from that of the main sheet.

By this means, the electric motor of the drive system drives the pulling cable of the flexible drive transmission assembly to drive the pull-out profile of the main sheet and the lever element of the secondary sheet to move, so that the main sheet and the secondary sheet are unfolded and folded. Wherein the carrier is assigned to the second cable puller, and the carrier carries or releases the lever element of the secondary sheet according to the position of the second cable puller, the time point of driving the secondary sheet to unfold is delayed.

[0005] Although the aforementioned CN 112829552 B patent case discloses a "light shielding device for side window of motor vehicle" which can provide a mechanism for driving the unfolding and folding of the main sheet and the secondary sheet by using a single set of drive system.

[0075] The technical means adopted by the present application to achieve the predetermined purposes are further explained in the following description in conjunction with the accompanying drawings and embodiments of the present application.

[0076] As shown in Figure 1 , Figure 8 and Figure 11 , two embodiments of the integrated electric drive mechanism 3 of the side window curtain 10 and the corner window curtain 20 of the present application are disclosed, which can be installed in a vehicle door of a motor vehicle to drive the side window curtain 10 at the side window of the vehicle door and the corner window curtain 20 at the corner window beside the side window, the side window curtain 10 can be longitudinally unfolded and retracted at the side window, and the corner window curtain 20 can be transversely unfolded and retracted at the corner window. The area of the corner window is smaller than that of the side window, and the unfolding and retracting stroke of the corner window curtain 20 is smaller than that of the side window curtain 10.

[0077] As shown in Figure 1 , Figure 3 and Figure 11As shown, the side window curtain 10 is basically connected to a side window curtain roller assembly 13 and can be automatically rolled up by the side window curtain roller assembly 13. The side window curtain roller assembly 13 is horizontally arranged below the side window, and a longitudinal guide rail 12 is provided on each side of the side window. The two ends of the curtain side panel 11 of the side window curtain 10 can be driven to move up and down along the longitudinal guide rails 12 on both sides of the side window. The corner window curtain 20 is connected to a corner window curtain roller assembly 25 and can be automatically rolled up by the corner window curtain roller assembly 25. The corner window curtain roller assembly 25 is vertically arranged on the pillar between the corner window and the side window. A horizontal guide rail 24 is provided below the corner window. The rocker arm 22 connected to the curtain side panel 21 of the corner window curtain 20 moves horizontally along the horizontal guide rail 24 below the corner window with its bottom slider 23. Both the side window curtain roller assembly 13 and the corner window curtain roller assembly 25 are existing products, and their specific composition and structure will not be described in detail here.

[0078] like Figure 3 and Figure 4 As shown, a curtain storage groove 14 can be further provided between the bottom ends of the two longitudinal guide rails 12. The side window curtain roller assembly 13 is installed in the curtain storage groove 14. The side window curtain 10 and its curtain side panel 11 can enter and exit through the slot at the top of the curtain storage groove 14. Preferably, a groove cover 15 can be pivotally installed at the top of the curtain storage groove 14.

[0079] like Figure 1 , Figure 2 As shown, this invention discloses an embodiment of the integrated electric drive mechanism 3, which includes a moving guide rail 30, a drive assembly 40, and a clutch transmission assembly 50. Wherein:

[0080] like Figure 1 , Figure 2As shown, the moving rail 30 is disposed between the bottom ends of the two longitudinal rails 12 transversely, and one end of the moving rail 30 corresponds to one end of the transverse rail 24. The moving rail 30 has a curtain active stroke L matching the expansion stroke of the side window curtain 10, and has a stroke difference based on the expansion stroke of the corner window curtain 20 being shorter than the expansion stroke of the side window curtain 10. The transverse rail 24 provides the expansion stroke of the corner window curtain 20 to be smaller than the curtain active stroke L of the moving rail 30. In cooperation with the configuration of the clutch transmission assembly 50, the curtain active stroke L is set to have a stroke origin P1 away from one end of the transverse rail 24, and a stroke end P2 adjacent to the other end of the transverse rail 24. The stroke origin P1 and the stroke end P2 have a clutch switching point P3 therebetween, and the clutch switching point P3 to the stroke end P2 is a linkage section L1. The distance of the linkage section L1 matches the stroke distance of the slider 23 in the transverse rail 24. In the foregoing, the moving rail 30 can be an independent component, or, as shown in Figure 2 and Figure 3 As shown, when the curtain storage groove 14 is arranged in the vehicle door, the moving rail 30 can be additionally arranged at the side of the curtain storage groove 14, or the moving rail 30 can be formed at the side of the curtain storage groove 14.

[0081] As shown in Figure 1 , Figure 2 , Figure 6 and Figure 7 The driving assembly 40 includes an electric motor 41, and a first pull wire 42 and a second pull wire 43 capable of being driven forward and reversely by the electric motor 41. The first pull wire 42 and the second pull wire 43 are connected to the two ends of the curtain side plate 11 in the two longitudinal rails 12 in tension. The electric motor 41 drives the two ends of the curtain side plate 11 to move up and down along the two longitudinal rails 12 through the first pull wire 42 and the second pull wire 43 synchronously, and drives the side window curtain 10 to expand upward and to contract downward. In the embodiment, the spindle of the electric motor 41 is coaxially connected to a first winding wheel 44 and a second winding wheel 45. The first pull wire 42 is connected to the first winding wheel 44, and the second pull wire 43 is connected to the second winding wheel 45. In the embodiment, the first pull wire 42 is arranged in the longitudinal rail 12 away from the corner window curtain 20 to connect one end of the curtain side plate 11 of the side window curtain 10 through the moving rail 30, and the second pull wire 43 is arranged in the longitudinal rail 12 adjacent to the corner window curtain 20 to connect the other end of the curtain side plate 11 of the side window curtain 10. Figure 6 , Figure 7 As shown, the first pull wire 42 and the second pull wire 43 can also be maintained in tension through a tension adjuster 46.

[0082] As shown in Figure 2 , Figure 5 and Figure 6As shown, the clutch transmission assembly 50 includes a clutch transmission member 51 and a linkage member 52 operable to engage or disengage from the clutch transmission member 51. The clutch transmission member 51 is driven by the first pull cable 42 to move forward and backward within the curtain travel stroke L of the moving guide rail 30. The linkage member 52 can move within the linkage section L1 of the moving guide rail 30 and the transverse guide rail 24, and drive the slider 23 located on the transverse guide rail 24. Specifically, the forward-moving clutch transmission member 51 can engage with the linkage member 52 at the clutch switching point P3 within the curtain travel stroke L to generate linkage; the reverse-moving clutch transmission member 51 can disengage from the linkage member 52 at the clutch switching point P3 within the curtain travel stroke L without engaging.

[0083] like Figure 2 As shown above, the forward movement of the clutch transmission component 51 refers to moving from the origin P1 to the end point P2 along the travel stroke L of the curtain, causing the side window curtain 10 to be pulled upward. The reverse movement of the clutch transmission component 51 refers to moving from the end point P2 to the origin P1 along the travel stroke L of the curtain, causing the side window curtain 10 to be pulled downward.

[0084] Furthermore, as the clutch transmission component 51 moves forward, driven by the first pull cable 42 from the origin point P1 of the curtain's travel stroke L to the end point P2, the first pull cable 42 simultaneously causes the side curtain 10's edge panel to unfold upwards. When the clutch transmission component 51 moves forward to the clutch switching point P3, it can connect with the linkage component 52 to cause the corner curtain 20 and the side curtain 10 to unfold together until the clutch transmission component 51 stops at the end point P2 of the linkage section L1, at which point the side curtain 10 and the corner curtain 20 are simultaneously unfolded.

[0085] As the clutch transmission component 51, moving in the reverse direction, is driven by the first pull cable 42 to move from the end point P2 of the curtain's travel stroke L towards the origin P1, the clutch transmission component 51, moving in the reverse direction, can connect with the linkage component 52 between the end point P2 and the clutch switching point P3 in the curtain's travel stroke L, causing the corner curtain 20 and the side curtain 10 to close in conjunction. When the clutch transmission component 51 moves to the clutch switching point P3 in the curtain's travel stroke L, it automatically disengages from the linkage component 52 and stops moving. At this time, the corner curtain 20 is closed, and the first pull cable 42 continues to drive the clutch transmission component 51 back to the origin P1, and the side curtain 10 continues to close until it stops.

[0086] like Figure 5 , Figure 6As shown, regarding the clutching structure between the clutch transmission member 51 and the linkage member 52, based on the linkage section L1 in the curtain moving stroke L is located in the moving guide rail 23, the clutch transmission member 51 is moved in the moving guide rail 23, the linkage member 52 is connected to the slider 23 from the moving guide rail 23 to the transverse guide rail 24, thereby controlling the first pull wire 42 to move only through the moving guide rail 30 but not through the transverse guide rail 24, so as to shorten the length of the first pull wire 42 and reduce the configuration mode of the first pull wire 42 around the deflection. Therefore, in the embodiment, the clutch transmission member 51 is a short member, and the linkage member 52 is a long strip-shaped member. The clutch transmission member 51 has an elastic clamping portion 511 at one end facing the linkage member 52, and the elastic clamping portion 511 has a plurality of elastic claw pieces 5110 arranged in a ring shape. The plurality of elastic claw pieces 5110 have radial bending and recovery elasticity, so that the elastic clamping portion 511 has radial expansion and recovery elasticity. The linkage member 52 has a combination end portion 521 at one end facing the clutch transmission member 51, and the combination end portion 521 can be clamped and linked with the elastic clamping portion 511 and can be operated to be separated from the elastic clamping portion 511. Preferably, the combination end portion 521 has a guide slope or arc surface at one end facing the elastic clamping portion 511. The guide slope or arc surface is guided to facilitate the elastic clamping portion 511 to expand and clamp the combination end portion 521, so as to improve the smoothness and correctness of the clutching action between the clutch transmission member 51 and the linkage member 52.

[0087] In the embodiment, the moving guide rail 30 and the transverse guide rail 24 are spaced relative to each other. In order to smoothly move the linkage member 52 between the moving guide rail 30 and the transverse guide rail 24, and assist the correct and smooth clutching between the clutch transmission member 51 and the linkage member 52, a guide pipe 31 is arranged between the transverse guide rail 24 and the moving guide rail 30. The linkage member 52 is arranged in the guide pipe 31. Preferably, the linkage member 52 is made of a flexible material. The slider 23 at the bottom end of the rocker arm 22 of the corner window curtain 20 is located outside the guide pipe 31 and can move in the transverse guide rail 24. The combination end portion 521 of the linkage member 52 is located outside the guide pipe 31 and can move in the moving guide rail 30.

[0088] Regarding the integrated electric drive mechanism 3 of the side window curtain 10 and the corner window curtain 20 of the utility model installed in the door of the motor vehicle, in combination with the use of the side window curtain 10 at the side window of the door and the corner window curtain 20 at the corner window of the side edge of the side window, please refer to Figure 1 、 Figure 2When both the corner curtain 20 and the side curtain 10 are closed, the corner curtain 20 is subjected to the winding force of the corner curtain roller assembly 25. The curtain edge strip 21 of the corner curtain 20 is close to the corner curtain roller assembly 25. At the same time, the slider 23 at the bottom of the rocker arm 22 connected to the curtain edge strip 21 is located near the guide tube 31. The linkage component 52 connected to the slider 23 goes from the transverse guide rail 24 through the guide tube 31 to the moving guide rail 30. The engagement end 521 of the linkage component 52 is located at the clutch switching point P3 of the curtain's movement stroke L. The clutch transmission component 51 connected to the first pull cable 42 is located at the stroke origin P1 of the curtain's movement stroke L.

[0089] When the side window curtain 10 and the corner window curtain 20 are unfolded, as follows Figures 8 to 10 As shown, the first pull line 42 and the second pull line 43, driven synchronously by the electric motor 41 of the drive assembly 40, drive the movable side panel of the side window curtain 10 to rise along the two longitudinal guide rails 12, so that the side window curtain 10 unfolds upward. During the upward unfolding of the side window curtain 10, the first pull cord 42 simultaneously pulls the clutch transmission component 51 in the forward direction, moving it from the origin P1 of the curtain's travel stroke L along the moving guide rail 30 towards the end point P2. When the clutch transmission component 51 moves forward to the clutch switching point P3, it engages with the coupling end 521 of the linkage component 52 with its elastic buckle, thus linking the clutch transmission component 51 with the linkage component 52. The first pull cord 42 drives the clutch transmission component 51 to move forward along the moving guide rail 30, and the linkage component 52 drives the slider 23 at the bottom of the rocker arm 22 connecting the movable side strip of the corner curtain 20 to move along the transverse guide rail 24, causing the corner curtain 20 to unfold laterally until the clutch transmission component 51 stops at the end point P2 of the linkage section L1. At this point, the side window curtain 10 and the corner curtain 20 are unfolded simultaneously. That is, after the clutch transmission component 51 engages with the linkage component 52, the linkage section L1 between the clutch switching point P3 and the end point P2 of the travel on the moving guide rail 30 can enable the side window curtain 10 and the corner window curtain 20 to be opened in a coordinated manner.

[0090] When closing the side window curtain 10 and the corner window curtain 20, as Figure 9 and Figure 2As shown, the first pull line 42 and the second pull line 43, driven synchronously by the electric motor 41 of the drive assembly 40, drive the movable side plate of the side window curtain 10 to descend along the two longitudinal guide rails 12 in the opposite direction. At the same time, the side window curtain 10 is automatically rolled up by the side window curtain roller assembly 13, causing the side window curtain 10 to close downward. During the process of the side window curtain 10 being driven to close downwards, the first pull cord 42 pulls the clutch transmission component 51 in the opposite direction, moving it along the curtain's travel stroke L from the end point P2 to the origin P1 of the travel stroke. At the same time, the clutch transmission component 51 is linked with the linkage component 52, and the corner curtain roller assembly 25 automatically rolls up the corner curtain 20, causing the corner curtain 20 to close. When the clutch transmission component 51 moves in the opposite direction to the clutch switching point P3, the first pull cord 42 drives the clutch transmission to move in the opposite direction. The corner curtain roller assembly 25 automatically rolls up the corner curtain 20, generating resistance, which allows the elastic buckle of the clutch transmission component 51 to naturally disengage from the engagement end 521 of the linkage component 52, thus disengaging the linkage relationship. At this time, the corner curtain 20 is closed. The first pull cable 42 continuously drives the clutch transmission component 51 to move in the opposite direction along the moving guide rail 30. The first pull cable 42 and the second pull cable 43 simultaneously drive the side window curtain 10 to close until the clutch transmission component 51 moves to the stroke origin P1 of the linkage section L1 and stops resetting. The side window curtain 10 then completes to close.

[0091] like Figures 11 to 14 As shown, this invention discloses another embodiment of the integrated electric drive mechanism 3, which includes a moving guide rail 30, a drive assembly 40, and a clutch transmission assembly 60. Wherein:

[0092] like Figures 11 to 14 As shown, the movable guide rail 30 is horizontally disposed between the bottom ends of the two longitudinal guide rails 12, with one end of the movable guide rail 30 corresponding to the adjacent end of the transverse guide rail 24. The movable guide rail 30 has a curtain movement stroke L that matches the unfolding stroke of the side window curtain 10. Since the unfolding stroke of the corner window curtain 20 is shorter than that of the side window curtain 10, resulting in a stroke difference, the transverse guide rail 24 provides that the unfolding stroke of the corner window curtain 20 is less than the curtain movement stroke L of the movable guide rail 30. In accordance with the structure of the clutch transmission assembly 50, the middle section of the moving guide rail 30 is set as the origin point P1 of the curtain's travel stroke L, the other end of the transverse guide rail 24 away from the moving guide rail 30 is the end point P2 of the curtain's travel stroke L, the end of the transverse guide rail 24 close to the moving guide rail 24 is a clutch switching point P3, and the distance from the clutch switching point P3 to the end point P2 is a linkage section L1. The distance of the linkage section L1 is equal to the travel distance of the slider 23 on the transverse guide rail 24.

[0093] As previously mentioned Figures 1 to 3In the embodiment shown, the movable guide rail 30 can be a separate component, or the movable guide rail 30 can be additionally assembled on the side of the curtain storage groove 14, or the movable guide rail 30 can be formed on the side of the curtain storage groove 14.

[0094] like Figures 11 to 14 As shown, the specific composition of the drive assembly 40 is the same as that of the previously described embodiment, and includes an electric motor 41, and a first pull cable 42 and a second pull cable 43 that can be driven by the electric motor 41 in both forward and reverse directions. The first pull cable 42 and the second pull cable 43 are tensioned and connected to the two ends of the curtain side panel 11 that extend into the two longitudinal guide rails 12. The first pull cable 42 passes through the moving guide rail 30, and the electric motor 41 drives the two ends of the curtain side panel 11 to move up and down along the two longitudinal guide rails 12 simultaneously through the first pull cable 42 and the second pull cable 43, thereby causing the side window curtain 10 to unfold upward and close downward. For other specific components of the drive assembly 40, please refer to the previously described embodiment, and will not be repeated here.

[0095] like Figures 11 to 14 As shown, the clutch transmission assembly 60 includes a clutch transmission member 61 and a linkage member 62 operable to engage and disengage with the clutch transmission member 61. The clutch transmission member 61 can be driven by the first pull cable 42 to move forward and backward within the curtain's travel stroke L. The linkage member 62 can move within the linkage section L1 (i.e., the transverse guide rail 24) of the moving guide rail 30 and drive the slider 23 located on the transverse guide rail 24 to move forward and backward. Specifically, the clutch transmission member 61 moving forward can engage with the linkage member 62 at the clutch switching point P3 within the curtain's travel stroke L to generate linkage; the clutch transmission member 61 moving backward can disengage from the linkage member 62 at the clutch switching point P3 within the curtain's travel stroke L without engaging.

[0096] In the foregoing, the forward movement of the clutch transmission component 61 refers to moving from the origin P1 to the end point P2 along the travel stroke L of the curtain, causing the side window curtain 10 to be pulled upward. The reverse movement of the clutch transmission component 61 refers to moving from the end point P2 to the origin P1 along the travel stroke L of the curtain, causing the side window curtain 10 to be pulled downward.

[0097] Furthermore, as the clutch transmission component 61 moves forward, driven by the first pull cable 42 from the origin point P1 of the curtain's travel stroke L to the end point P2, the first pull cable 42 simultaneously causes the side curtain 10's edge panel to unfold upwards. When the clutch transmission component 51 moves forward to the clutch switching point P3, it can connect with the linkage component 62 to cause the corner curtain 20 and the side curtain 10 to unfold together until the clutch transmission component 61 stops at the end point P2 of the linkage section L1, at which point the side curtain 10 and the corner curtain 20 are simultaneously unfolded.

[0098] The reverse motion clutch transmission member 61 is driven by the first pull wire 42 to move from the end point P2 of the curtain active stroke L to the original point P1, and during the movement, the reverse motion clutch transmission member 61 is connected to the linkage member 62 between the end point P2 and the clutch switching point P3 of the curtain active stroke L to link the corner window curtain 20 and the side window curtain 10, and when the reverse motion clutch transmission member 61 moves to the clutch switching point P3 of the curtain active stroke L, the linkage is automatically disconnected from the linkage member 62, and at this time, the corner window curtain 20 is fully closed, and the first pull wire 42 continues to drive the reverse motion clutch transmission member 61 to the original point P1, and the side window curtain 10 is continuously closed to stop.

[0099] As shown in the embodiment, regarding the clutch structure between the reverse motion clutch transmission member 61 and the linkage member 62 of the clutch transmission assembly 60, based on the curtain active stroke L extending from the moving guide rail 23 to the other end of the transverse guide rail 24, in order to control the first pull wire 42 to move only through the moving guide rail 30 without passing through the transverse guide rail 24, so as to shorten the length of the first pull wire 42 and reduce the deflection of the first pull wire 42, the reverse motion clutch transmission member 61 is a long member in the form of a rod, and the linkage member 62 is a short member in the form of a block, and the two can be connected and disconnected relative to each other.

Preferably, one end of the combination end portion 621 facing the resilient clamping portion 611 is formed as a guide inclined surface or an arc surface, and the guide inclined surface or the arc surface is guided to facilitate the expansion of the resilient clamping portion 611 to clamp the combination end portion 621, and to improve the smoothness and correctness of the clutching action between the reverse motion clutch transmission member 61 and the linkage member 62.
