Description

Technical Field

[0001] This invention relates to an electric curtain device for motor vehicles, and more particularly to an integrated electric drive mechanism that integrates electric curtain devices for side windows and corner windows of motor vehicles, enabling the side window curtains and corner window curtains to open and close in conjunction. Background Technology

[0002] Currently, the side and rear door windows of motor vehicles are typically designed to fit the vehicle's body shape, consisting of a liftable side window and a fixed corner window located behind it. To provide adequate sun shading for the side window and the corner window behind it, side window curtains are installed, and corner window curtains are installed in the corner window behind it. Previously, electric curtain devices installed on vehicle windows consisted of a curtain that could be rolled up by a curtain roller assembly. The ends of one side strip of the curtain were connected to a motor assembly via flexible transmission elements. The motor assembly, through the flexible transmission elements, moved the curtain side strip, and combined with the automatic rolling force of the curtain roller assembly, allowed the curtain to open and close. Therefore, both the side window curtain and the corner window curtain required separate electric drive mechanisms, resulting in a complex and costly overall design.

[0003] To streamline the electric drive mechanism of both side window curtains and corner window curtains, a patent application (CN112829552B) discloses a "light-shielding device for a side window of a motor vehicle." This device includes a main sheet (side window curtain), a secondary sheet (corner window curtain), and a drive system. The main sheet is connected to a horizontally rotatable winding shaft, and a pull-out profile (the movable side panel of the side window curtain) is provided on one side of the main sheet in the pull-out direction. When the main sheet is unfolded and retracted, the two ends of the pull-out profile move vertically up and down along a first and second guide rail fixed to the vehicle, allowing the main sheet to unfold upwards and retract downwards. The secondary sheet is located behind the main sheet and connected to a longitudinally rotatable winding shaft. The secondary sheet can be pulled out laterally, in a different direction than the upward pull-out of the main sheet, and the main and secondary sheets have unequal pull-out lengths. The secondary sheet has a lever element on the pull-out piece (i.e., the movable edge strip of the corner curtain) on the pull-out side. The bracket at the bottom of the lever element is installed in the horizontally arranged arc-shaped third guide rail and can move horizontally along the arc-shaped third guide rail while generating longitudinal movement.

[0004] The aforementioned drive system includes a flexible drive transmission assembly and an electric motor. The flexible drive transmission assembly extends longitudinally and is positioned within the regions of the first, second, and third guide rails. Driven by the electric motor, the flexible drive transmission assembly's cable pulling system includes two cable reels and a carrier. Each cable reel is assigned to a first cable pulling member and a second cable pulling member on the first and second guide rails of the main sheet. The second cable pulling member on the second guide rail of the main sheet further deflects along the third guide rail of the secondary sheet. The carrier is assigned to the second cable pulling member and, depending on the position of the second cable pulling member, carries or releases the lever element of the secondary sheet. This causes the electric motor of the drive system to drive the pulling cable of the flexible drive transmission assembly, thereby moving the pull-out profile of the main sheet and the lever element of the secondary sheet, causing the main and secondary sheets to unfold and retract. The carrier, assigned to the second cable pulling member, carries or releases the lever element of the secondary sheet according to its position, delaying the unfolding time of the secondary sheet.

[0005] While the "sunshade device for a side window of a motor vehicle" disclosed in the aforementioned CN 112829552 B patent provides a mechanism for using a single drive system to drive the unfolding and retraction of the main sheet and secondary sheet, its second cable pull member, which deflects along the lateral guide and connects to the carrier via the second guide rail of the main sheet, and then connects to the bracket of the third guide rail via the lever element, and the second cable pull member is then deflected at the end of the third guide rail and wound around the cable reel, the winding path of the second cable pull member of the aforementioned sunshade device is complex and the distance is relatively long. When it is installed in a motor vehicle, not only is the assembly operation difficult, time-consuming and labor-intensive, but the second cable pull member also forms multiple deflections over a long distance, which can easily lead to errors or uneven operation during transmission. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an integrated electric drive mechanism for side window curtains and corner window curtains to improve the technical problems of the second cable pulling member of the known light-blocking device having a complex and long winding path, difficult and time-consuming assembly operation, and multiple deflections of the second cable pulling member, which are prone to errors or uneven operation during transmission.

[0007] The technical solution proposed in this invention is: to provide an integrated electric drive mechanism for a side window curtain and a corner window curtain, which can be installed in a vehicle door to drive a side window curtain located at the side window of the door that can be opened and closed longitudinally and a corner window curtain located at the side of the side window that can be opened and closed laterally. The two ends of the curtain edge plate of the side window curtain can be driven to move up and down along the longitudinal guide rails on both sides of the side window, and the rocker arm connected to the curtain edge strip of the corner window curtain moves laterally along a transverse guide rail below the corner window with its bottom slider; the integrated electric drive mechanism includes:

[0008] A movable guide rail is horizontally disposed between the bottom ends of the two longitudinal guide rails, corresponding to the end adjacent to the horizontal guide rail. The movable guide rail has a curtain movement stroke that matches the opening stroke of the side window curtain. The end of the curtain movement stroke away from the horizontal guide rail is a stroke origin, and the other end adjacent to the horizontal guide rail is a stroke end. There is a clutch switching point between the stroke origin and the stroke end. The distance from the clutch switching point to the stroke end is a linkage section. The distance of the linkage section matches the travel distance of the slider on the horizontal guide rail.

[0009] A drive assembly includes an electric motor, and a first pull cable and a second pull cable that can be driven by the electric motor. The first and second pull cables synchronously drive both ends of the curtain side panel to move up and down along two longitudinal guide rails. The first pull cable passes through the moving guide rail.

[0010] A clutch transmission assembly includes a clutch transmission member capable of forward and reverse movement of the curtain during its travel along the moving guide rail, driven by the first pull cable; and a linkage member capable of moving along the linkage section of the moving guide rail and the transverse guide rail, the linkage member being connected to the slider located on the transverse guide rail, wherein:

[0011] During the movement of the clutch transmission component between the origin and end point of the curtain's travel stroke, the forward-moving clutch transmission component can connect with the linkage component at the clutch switching point, causing the corner curtain and the side curtain to open in linkage. The reverse-moving clutch transmission component can disengage from the linkage component at the clutch switching point and not be linked. After the corner curtain is closed, the side curtain continues to close.

[0012] Another technical solution proposed by this invention is: providing an integrated electric drive mechanism for a side window curtain and a corner window curtain, which can be installed in a vehicle door to drive a side window curtain located at the side window of the door that can be opened and closed longitudinally and a corner window curtain located at the corner window located on the side of the side window that can be opened and closed laterally. The two ends of the curtain edge panel of the side window curtain can be driven to move up and down along the longitudinal guide rails on both sides of the side window, and the rocker arm connected to the curtain edge strip of the corner window curtain moves laterally along a transverse guide rail below the corner window with its bottom slider; the integrated electric drive mechanism includes:

[0013] A movable guide rail is horizontally disposed between the bottom ends of the two longitudinal guide rails, corresponding to the end adjacent to the transverse guide rail, and has a curtain movement stroke extending from the movable guide rail to the transverse guide rail and matching the opening stroke of the side window curtain. One end of the curtain movement stroke is located in the middle section of the movable guide rail as a stroke origin, and the other end of the curtain movement stroke is located on the transverse guide rail away from the movable guide rail as a stroke end point. A clutch switching point is located on the transverse guide rail adjacent to the movable guide rail. The distance from the clutch switching point to the stroke end point is a linkage section, and the distance of the linkage section matches the travel distance of the slider on the transverse guide rail.

[0014] A drive assembly includes an electric motor, and a first pull cable and a second pull cable that can be driven by the electric motor. The first and second pull cables synchronously drive both ends of the curtain side panel to move up and down along two longitudinal guide rails. The first pull cable passes through the moving guide rail.

[0015] A clutch transmission assembly includes a clutch transmission member capable of forward and reverse movement during the curtain's travel stroke, driven by the first pull cable, and a linkage member connected to the slider and positioned in the linkage section of the transverse guide rail, wherein:

[0016] During the movement of the clutch transmission component between the origin and end point of the curtain's travel stroke, the forward-moving clutch transmission component can connect with the linkage component at the clutch switching point, causing the corner curtain and the side curtain to open in linkage. The reverse-moving clutch transmission component can disengage from the linkage component at the clutch switching point and not be linked. After the corner curtain is closed, the side curtain continues to close.

[0017] The present invention achieves the following beneficial effects: The integrated electric drive mechanism for the side window curtain and corner window curtain utilizes its moving guide rail, which is laterally arranged between the bottom ends of two longitudinal guide rails and adjacent to and corresponding to the transverse guide rails. The first and second pull cables in the drive assembly, which can be driven by an electric motor, can synchronously drive the two ends of the side window curtain's side panel to move up and down along the two longitudinal guide rails. The clutch transmission assembly includes a clutch transmission component and a linkage component. The clutch transmission component can be driven by the first pull cable to move forward and backward during the curtain's travel. The linkage component... The component can move within the linkage section and the transverse guide rail. The bottom end of the rocker arm of the movable side strip of the corner window curtain is located on the slider of the transverse guide rail. During the process of the clutch transmission component being driven to move between the origin and end point of the curtain's active stroke, the forward-moving clutch transmission component can connect with the linkage component at the clutch switching point to make the corner window curtain and the side window curtain open in linkage. The reverse-moving clutch transmission component can disengage from the linkage component at the clutch switching point and not be linked. After the corner window curtain is closed, the side window curtain continues to close.

[0018] Therefore, based on the ability to achieve the linkage between the side window curtain and the corner window curtain by a single drive component, the clutch transmission component is used to adjust the difference in the opening and closing stroke of the side window curtain and the corner window curtain by utilizing the clutch transmission component and the linkage component that can be relatively disengaged and engaged, and limiting the position and stroke of the linkage component. In addition, the first pull cable only needs to connect to the clutch transmission component and is wound around the longitudinal guide rail and the moving track and connected to the drive component. It does not need to go around the transverse guide rail of the corner window curtain. This simplifies the winding method, improves the ease of assembly, shortens the working time, and also reduces the deflection and winding position of the pull cable in the mechanism. This ensures the smooth operation of the linkage between the side window curtain and the corner window curtain and avoids the risk of operation error. Attached Figure Description

[0075] The following description, in conjunction with the accompanying drawings and embodiments of the invention, further illustrates the technical means employed by the present invention to achieve its intended purpose.

[0076] like Figure 1 , Figure 8 and Figure 11 The diagram illustrates two embodiments of the integrated electric drive mechanism 3 for the side window curtain 10 and corner window curtain 20 of the present invention. This mechanism can be installed in the door of a motor vehicle to drive the side window curtain 10 located at the side window of the door and the corner window curtain 20 located at the corner window beside the side window. The side window curtain 10 can be longitudinally unfolded and retracted at the side window, while the corner window curtain 20 can be laterally 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 less than that of the side window curtain 10.

[0077] like Figure 1 , Figure 3 and Figure 11 As 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. The groove cover 15 is connected to the curtain storage groove 14 with one or more torsion springs. Each end of the groove cover 15 is connected to a groove cover opening and closing mechanism 16 that can be raised and lowered by the curtain side panel 11. The groove cover 15 is opened before the side window curtain 10 is driven to unfold upward from the curtain storage groove 14, and the groove cover 15 is automatically closed after the side window curtain 10 is closed into the curtain storage groove 14. The technical content of the slot cover opening and closing mechanism 16 for opening and closing the slot cover of the curtain storage slot 14 has many specific and feasible technical solutions in the prior art, and the slot cover opening and closing mechanism 16 is not a necessary technical content in the technical solution of the present invention, so it will not be described in detail here.

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

[0080] in:

[0081] like Figure 1 , Figure 2 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 end of the curtain's travel stroke L furthest from the transverse guide rail 24 is designated as the travel origin P1, and the other end adjacent to the transverse guide rail 24 is designated as the travel end point P2. A clutch switching point P3 exists between the travel origin P1 and the travel end point P2. The distance from the clutch switching point P3 to the travel end point P2 constitutes a linkage section L1, and the distance of this linkage section L1 matches the travel distance of the slider 23 on the transverse guide rail 24. As described above, the moving guide rail 30 can be an independent component, or, as... Figure 2 and Figure 3As shown, when the door is equipped with a curtain storage slot 14, the movable guide rail 30 can be additionally assembled on the side of the curtain storage slot 14, or the movable guide rail 30 can be formed on the side of the curtain storage slot 14.

[0082] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the drive assembly 40 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 electric motor 41 synchronously drives the two ends of the curtain side panel 11 to move up and down along the two longitudinal guide rails 12 through the first pull cable 42 and the second pull cable 43, thereby causing the side window curtain 10 to unfold upward and retract downward. In this embodiment, the spindle of the electric motor 41 is coaxially connected to a first winding reel 44 and a second winding reel 45. The first pull cable 42 is connected to the first winding reel 44, and the second pull cable 43 is connected to the second winding reel 45. In this embodiment, the first pull cord 42 is disposed in the longitudinal guide rail 12 away from the corner curtain 20, connecting one end of the curtain edge plate 11 of the side curtain 10 through the movable guide rail 30, and the second pull cord 43 is disposed in the longitudinal guide rail 12 adjacent to the corner curtain 20, connecting the other end of the curtain edge plate 11 of the side curtain 10. Figure 6 , Figure 7 As shown, the first pull cable 42 and the second pull cable 43 can also be kept taut by the tension adjuster 46.

[0083] like Figure 2 , Figure 5 and Figure 6 As 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.

[0084] like Figure 2As 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.

[0085] 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.

[0086] 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.

[0087] like Figure 5 , Figure 6As shown, regarding the clutch transmission component 51 and the linkage component 52, the linkage section L1 in the curtain's travel L is located on the moving guide rail 23. The clutch transmission component 51 moves in the moving guide rail 23, and the linkage component 52 extends from the moving guide rail 23 to the transverse guide rail 24 to connect to the slider 23. This controls the first pull cable 42 to pass only through the moving guide rail 30 and not through the transverse guide rail 24, in order to shorten the length of the first pull cable 42 and reduce the configuration of the first pull cable 42 winding and deflecting. Therefore, in this embodiment, the clutch transmission component 51 is a short component, while the linkage component 52 is a long strip component. The clutch transmission component 51 has an elastic fastening portion 511 at the end facing the linkage component 52. The elastic fastening portion 511 has a plurality of elastic claws 5110 arranged in a ring. The plurality of elastic claws 5110 have radial bending and recovery elasticity, so that the elastic fastening portion 511 has radial expansion and contraction recovery elasticity. The linkage component 52 has a connecting end 521 at the end facing the clutch transmission component 51. The connecting end 521 can be fastened by the elastic fastening portion 511 for linkage, and can be operated to disengage from the elastic fastening portion 511. Preferably, the end of the engagement end 521 facing the elastic fastening part 511 forms a guide slope or arc surface. The guide slope or arc surface helps the elastic fastening part 511 to expand and clamp the engagement end 521, thereby improving the smoothness and correctness of the engagement and disengagement between the clutch transmission member 51 and the linkage member 52.

[0088] In this embodiment, the moving guide rail 30 and the transverse guide rail 24 are spaced apart and opposite each other. In order to enable the linkage component 52 to move smoothly between the moving guide rail 30 and the transverse guide rail 24, and at the same time to assist the clutch transmission component 51 and the linkage component 52 to engage and disengage correctly and smoothly, a conduit 31 is provided between the transverse guide rail 24 and the moving guide rail 30. The linkage component 52 passes through the conduit 31. Preferably, the linkage component 52 is made of a flexible material. The slider 23 located at the bottom of the rocker arm 22 of the corner curtain 20 is located outside the conduit 31 and can move in the transverse guide rail 24. The engaging end 521 of the linkage component 52 is located outside the conduit 31 and can move in the moving guide rail 30.

[0089] Regarding the integrated electric drive mechanism 3 for the side window curtain 10 and corner window curtain 20 of the present invention, which is installed in the door of a motor vehicle, please refer to the usage scenarios of the side window curtain 10 located at the side window of the door and the corner window curtain 20 located at the corner window on the side of the side window. 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.

[0090] 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 using an 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 simultaneously unfolded. 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.

[0091] 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 fall down. 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 movement stroke L of the moving guide rail 30 from the stroke end point P2 towards the stroke origin P1. At the same time, the clutch transmission component 51 is linked with the linkage component 52, and the corner window curtain roller assembly 25 automatically rolls up the corner window curtain 20, causing the corner window 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 window curtain roller assembly 25 automatically rolls up the corner window curtain 20, generating resistance, so that the elastic buckle of the clutch transmission component 51 and the engagement end 521 of the linkage component 52 can naturally disengage and release the linkage relationship. At this time, the corner window 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.

[0092] like Figures 11 to 14 As shown, another embodiment of the integrated electric drive mechanism 3 of the present invention is disclosed. This integrated electric drive mechanism 3 includes a moving guide rail 30, a drive assembly 40, and a clutch transmission assembly 60. Wherein:

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] As the clutch transmission component 61, 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 61, moving in the reverse direction, can connect with the linkage component 62 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 61 moves to the clutch switching point P3 in the curtain's travel stroke L, it automatically disengages from the linkage component 62 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 61 back to the origin P1, and the side curtain 10 continues to close until it stops.

[0100] like Figures 11 to 14 In the embodiment shown, regarding the clutch transmission component 61 and the linkage component 62 of the clutch transmission assembly 60, based on the fact that the curtain's travel stroke L extends from the moving guide rail 23 to the other end of the transverse guide rail 24, in order to control the first pull cable 42 to pass only through the moving guide rail 30 and not through the transverse guide rail 24, in order to shorten the length of the first pull cable 42 and reduce the configuration of the first pull cable 42 winding and deflection, the clutch transmission component 61 adopts a rod-shaped long component, and the linkage component 62 adopts a block-shaped short component, and the two can be relatively engaged and disengaged.

[0101] like Figures 11 to 14 As shown, the clutch transmission component 61 includes a transmission connection portion 61a and an extension rod portion 61b located at one end of the transmission connection portion 61b facing the transverse guide rail 24. The transmission connection portion 61a and the extension rod portion 61b can be integrally formed components or two independent components combined together. The transmission connection portion 61a is connected to the first pull cable and can move back and forth in the moving guide rail 30. The end of the extension rod portion 61 (i.e., the end facing the linkage component 62) has an elastic fastening portion 611. The extension rod portion 61 can move from the moving guide rail 30. The device moves back and forth between rail 30 and transverse guide rail 24. The elastic fastening part 611 has multiple elastic claws arranged in a ring. These multiple elastic claws have radial bending and recovery elasticity, giving the elastic fastening part 611 radial expansion and contraction recovery elasticity. The linkage component 62 is provided on the slider 23. The end of the linkage component 62 facing the clutch transmission component 61 has a connecting end 621. The connecting end 621 can be engaged and linked by the elastic fastening part 611, and can be operated to disengage from the elastic fastening part 611. Preferably, the end of the connecting end 621 facing the elastic fastening part 611 forms a guide slope or arc surface. Through the guidance of the guide slope or arc surface, the elastic fastening part 611 expands to clamp the connecting end 621, improving the smoothness and accuracy of the clutch action between the clutch transmission component 61 and the linkage component 62.

[0102] In this embodiment, the moving guide rail 30 and the transverse guide rail 24 are spaced apart and opposite each other. In order to enable the clutch transmission member 61 to move smoothly between the moving guide rail 30 and the transverse guide rail 24, and at the same time to assist the clutch transmission member 61 and the linkage member 62 to engage and disengage correctly and smoothly, a conduit 31 is provided between the transverse guide rail 24 and the moving guide rail 30. Preferably, the extension rod 61b of the clutch transmission member 61 is flexible. The extension rod 61b and the elastic fastening part 611 of the clutch transmission member 61 can pass through the conduit 31. The slider 23 located at the bottom of the rocker arm 22 of the corner curtain 20 is located outside the conduit 31 and can move in the transverse guide rail 24. The linkage member 62 connected with the slider 23 has its connecting end 621 facing the conduit 31. After the elastic fastening part 611 of the clutch transmission member 61 passes through the conduit 31, it can fasten the connecting end 621 of the linkage member 62.

[0103] The foregoing Figures 11 to 14 Another embodiment of the disclosed integrated electric drive mechanism 3 is installed in the door of a motor vehicle. Combined with the use of the side window curtain 10 located at the side window of the door and the corner window curtain 20 at the corner window on the side of the side window, its operation and actuation are generally the same as described above. Figures 1 to 9 The integrated electric drive mechanism 3 disclosed is the same and will not be described again here.

Although the present invention has been disclosed above by way of embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the technical solution of the present invention.
