Description

Technical Field

[0001] This application relates to the field of automotive technology, and in particular to a linkage drive device and vehicle for a side window sunshade. Background Technology

[0002] Currently, some motor vehicles are equipped with sunshades for their side windows. These sunshades effectively block ultraviolet rays and heat from the sun, reducing the interior temperature, lessening the burden on the air conditioning, and improving driving and riding comfort. They also block outside views, creating a private interior space that allows passengers to move more freely. Furthermore, they reduce direct sunlight damage to interior components such as seats, protecting the vehicle's interior.

[0003] Compared to traditional manually operated side window sunshades, motorized side window sunshades are becoming the mainstream.

[0004] Some vehicles have side windows designed in two parts to match the shape of the vehicle body, for example... Figure 1 As shown, the vehicle includes a main window and a triangular window (or corner window). The main window's glass can be raised and lowered to open and close, while the corner window's glass is fixed in shape and its size is smaller than the main window's. Because the main window and corner window are not the same size, and to provide sun shading for both the main window and the corner window, these vehicles are equipped with a main curtain for the main window and corner curtains for the corner windows. However, if separate drive mechanisms are used to operate the main curtain and corner curtain separately, the overall vehicle cost would be high. Utility Model Content

[0005] This application provides a linkage drive device and vehicle for a side window sunshade, which is used to achieve linkage drive of the main window curtain and corner window curtain of the vehicle's side window based on a single motor and double pulleys and double-line wheels, thereby reducing the overall vehicle cost.

[0006] In a first aspect, embodiments of this application provide a linkage drive device for a side window sunshade, wherein the side window may include a main window and a corner window, the side window sunshade includes a main window curtain and a corner window curtain, the linkage drive device is connected to the main window curtain and the corner window curtain, the main window curtain is housed in a main window curtain roller assembly, the main window curtain roller assembly is arranged horizontally, and the corresponding front guide rail assembly and rear guide rail assembly are arranged vertically, the main window curtain unfolds and retracts along the longitudinal direction of the front guide rail assembly and the rear guide rail assembly, the corner window curtain is housed in a corner window curtain roller assembly, the corner window curtain roller assembly is arranged vertically, and the corresponding corner window guide rail assembly is arranged horizontally, the corner window curtain unfolds and retracts horizontally along the corner window guide rail assembly, the linkage drive device may include:

[0007] A drive assembly includes a motor and a gear, wherein the output shaft of the motor is connected to the gear and is used to drive the gear to rotate;

[0008] The transmission assembly includes a drive shaft, a first threaded wheel, a second threaded wheel, a first transmission line, a second transmission line, a first pulley, and a second pulley. The drive shaft is connected to the gear, the first threaded wheel, and the second threaded wheel. The first transmission line is connected to the first threaded wheel, the first pulley, and the first end of the edge strip of the main curtain. The second transmission line is connected to the second threaded wheel, the second pulley, the second end of the edge strip of the main curtain, and the linkage structure of the corner curtain. The first pulley and the first threaded wheel are located at the top and bottom of the rear guide rail assembly, respectively, and the second pulley is located at the top of the front guide rail assembly. The motor drives the first threaded wheel and the second threaded wheel to rotate via the gear and the drive shaft. When the first threaded wheel and the second threaded wheel rotate, they drive the first transmission line to rotate around the first pulley and the second transmission line to rotate around the second pulley, thereby causing the main curtain to unfold and close.

[0009] The linkage assembly includes a linkage structure and a slider. The linkage structure is connected to the edge strip of the corner curtain, and the slider is connected to the second transmission line. During the process of the main curtain being opened by the second transmission line, when the slider hits the linkage structure of the corner curtain, the second transmission line, the linkage structure, and the slider drive the corner curtain to open.

[0010] Therefore, through the above design, a single motor and dual pulleys / dual-line wheels can be used to achieve linked drive of the main window curtains and corner window curtains on the vehicle's side windows, reducing overall vehicle cost. This design, based on sliders and a linkage structure, can achieve differentiated drive of the main window curtains and corner window curtains, with the differentiated trajectories conforming to the size differences between the two curtains. In other embodiments, similar modified structures can also be used to achieve linked drive of the main window curtains and corner window curtains; this application does not specifically limit this approach.

[0011] In one possible design, the side window is a vehicle door window, and the corner window is located behind the main window. The main window curtain roller assembly is horizontally arranged inside the outer tube assembly of the door, and the corner window curtain roller assembly is vertically arranged inside the window frame trim panel between the main window and the corner window.

[0012] In one possible design, at the same time, the first transmission line and the second transmission line rotate in opposite directions around the first pulley and the second pulley, respectively.

[0013] For example, if the side window is the left door window of a vehicle, during the process of the first transmission line and the second transmission line driving the main window curtain to unfold, the first transmission line rotates counterclockwise around the first pulley, and the second transmission line rotates clockwise around the second pulley.

[0014] Or, for example, if the side window is the right-side door window of the vehicle, during the process of the first transmission line and the second transmission line driving the main window curtain to unfold, the first transmission line rotates clockwise around the first pulley, and the second transmission line rotates counterclockwise around the second pulley.

[0015] In one possible design, the transmission assembly further includes a third pulley and a fourth pulley. The third pulley is located at the bottom of the front guide rail assembly, and the fourth pulley is located at the rear of the corner window guide rail assembly. The second transmission line winds around the bottom of the third pulley and the top of the fourth pulley. At the same time, the second transmission line rotates around the third pulley in the opposite direction to the fourth pulley.

[0016] In one possible design, the transmission assembly further includes a conduit disposed on the door and used to house the second transmission line, which moves within the conduit as it rotates around the second pulley.

[0017] One possible design also includes a protective shell, which is fitted over the outside of the gear, the drive shaft, the first spool, and the second spool.

[0018] Secondly, embodiments of this application also provide a vehicle, including a side window sunshade and a linkage drive device as described in any possible design of the first aspect above.

[0019] In one possible design, the vehicle may also include an end cap for securing the main curtain roller assembly of the side window sunshade within the outer tube assembly, the end cap being located at the edge of the outer tube assembly.

[0020] In one possible design, the vehicle includes at least one of a new energy vehicle, a hybrid vehicle, a range-extended electric vehicle, or a gasoline vehicle. The linkage drive system of this application can be applied to vehicles with different power types to reduce overall vehicle costs and ensure a better user experience. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0038] The terminology used in the following embodiments is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” “the,” and “this” are intended to also include expressions such as “one or more” unless the context clearly indicates otherwise.

[0039] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0040] This application provides a linkage drive device and vehicle for side window sunshade curtains, which is used to realize the linkage drive of the main window curtain and corner window curtain of the vehicle side window based on a single motor and double pulleys and double line wheels, thereby reducing the overall vehicle cost.

[0041] To better illustrate this application, the linkage drive device of the side window sunshade and the relationship between the linkage drive device and its terminal equipment will be described in detail below.

[0042] The side window in this embodiment of the application can be a side window of a vehicle, or simply a side window. This side window can be as follows: Figure 1 The diagram shows vehicle doors and windows, which can be the left and right windows of the rear doors or the left and right windows of the front doors; this embodiment does not specifically limit this. Side windows may include a main window 100 and corner windows 200. The main window is the main body of the window, and its glass can move longitudinally and be raised and lowered to open and close. Corner windows can be located behind the main window; their glass is usually fixed and serves to increase vehicle lighting and make the raising and lowering of the main window glass smoother.

[0043] It should be understood that Figure 1This is merely one example of a side window structure and does not constitute any limitation. In other embodiments, for example, the windows of the front doors of the vehicle may be configured to include a main window and a corner window. In this case, the corner window may be located, for example, in front of the main window, to reduce the driver's blind spot.

[0044] Regardless of the type of side window structure mentioned above, sunshades can be installed on the side windows to block sunlight and heat from the vehicle interior, as well as the view from outside, effectively reducing the interior temperature, protecting passenger privacy, and protecting the interior of the vehicle.

[0045] In some embodiments, the side window sunshades can also be designed in two parts to match the window structure, such as including a main window curtain and a corner window curtain. The main window curtain corresponds to the main window and its glass pane. When fully extended, the main window curtain covers an area roughly the same as the main window when closed, effectively blocking sunlight and outside views entering the vehicle through the main window. Similarly, the corner window curtain corresponds to the corner window and its glass pane. When fully extended, the corner window curtain covers an area roughly the same as the corner window, effectively blocking sunlight and outside views entering the vehicle through the corner window.

[0046] To reduce the overall vehicle cost, this application embodiment designs a linkage drive device for side window sunshades, which is used to achieve linkage drive of the main window curtain and corner window curtain of the same side window of the vehicle based on a single motor and double pulleys and double-line wheels.

[0047] Taking the aforementioned side window as an example, which is the window of the rear left-side door, such as Figure 2 As shown, the left-side windows of the vehicle may include the driver's side window 605 and the side windows of the rear doors. The side windows of the rear doors may include the main window 100 and the corner window 200. The side window sunshades may include the main window curtain 101 and the corner window curtain 201 (not shown in the figure), which are used to cover the light-transmitting areas of the main window glass and the corner window glass, respectively. The main window curtain 101 can be stored in the main window curtain roller assembly 102, which can be horizontally positioned on the left rear door and below the window frame of the main window 100. The corner window curtain 201 can be stored in the corner window curtain roller assembly 202, which can be stored in the trim panel 603 of the window frame between the main window 100 and the corner window 200. It should be understood that... Figure 2 The dashed box only schematically illustrates the deployment position of the main window curtain roller assembly 102 and does not constitute any limitation. The shape of the corner window 200 is only an example and does not constitute any limitation. In some embodiments, the corner window 200 may also take an irregular rectangular shape, which will be described in the embodiments below and will not be elaborated here.

[0048] The linkage drive device for the side window sunshade curtain in this embodiment can be connected to the main window curtain 101 and the corner window curtain 201 to realize the linkage drive of the main window curtain 101 and the corner window curtain 201.

[0049] In one example, such as Figure 3 As shown, the main curtain roller assembly 102 can be horizontally fixed inside the inner tube assembly 602 of the door via two end caps 604, and the inner tube assembly 602 can be fixed inside the outer tube assembly 601 of the door. The front guide rail assembly 103 and the rear guide rail assembly 104 corresponding to the main curtain roller assembly 102 are longitudinally arranged on both sides of the main window. The two ends of the main curtain roller assembly 102 are also connected to the bottom of the front guide rail assembly 103 and the rear guide rail assembly 104, respectively. The front guide rail assembly 103 and the rear guide rail assembly 104 are used to clamp the two ends of the edge strip 105 of the main curtain, respectively, as the first end 1051 and the second end 1052, so that the edge strip 105 of the main curtain moves longitudinally along the front guide rail assembly 103 and the rear guide rail assembly 104, thereby driving the main curtain 101 to unfold and close longitudinally along the front guide rail assembly and the rear guide rail assembly.

[0050] Meanwhile, the corner curtain 201 is housed within the corner curtain roller assembly 202, which is longitudinally positioned within the window frame trim 603 between the main window 100 and the corner window 200. The bottom of the corner curtain roller assembly 202 is connected to the front end of the corner window guide rail assembly 203 (the lower right corner of the corner window 200 in the figure, near the front of the vehicle). The corner window guide rail assembly 203 is laterally positioned at the bottom of the corner window 200. The edge strip 204 of the corner curtain is connected to the corner window guide rail assembly 203 via the corner curtain linkage structure 501 and moves laterally along the corner window guide rail assembly 203, thereby causing the corner curtain 201 to unfold and retract laterally along the corner window guide rail assembly 203.

[0051] To achieve synchronized operation of the main window curtain and the corner window curtain, such as Figure 4 , Figure 5 and Figure 6 As shown, the linkage drive device in this application embodiment can be designed to include:

[0052] (1) The drive assembly 300 includes a motor 301 and a gear 302. The output shaft 303 of the motor can be connected to the gear 302 to drive the gear 302 to rotate. Figure 4 As shown.

[0053] (2) Transmission assembly 400 includes transmission shaft 401, first pulley 402, second pulley 403, first transmission line 404, second transmission line 405, first pulley 406 and second pulley 407.

[0054] Among them, such as Figure 4 , Figure 5 and Figure 6 As shown, the drive shaft 401 is connected to the gear 302, the first spool 402, and the second spool 403. In an optional embodiment, the linkage drive device may further include a protective shell (not shown in the figure), which may be fitted over the outside of the gear 302, the drive shaft 401, the first spool 402, and the second spool 403.

[0055] like Figure 4 , Figure 5 and Figure 6 As shown, the first drive line 404 can be connected to the first pulley 402, the first pulley 406, and the first end 1051 of the side strip 105 of the main curtain. The second drive line 405 is connected to the second pulley 403, the second pulley 407, the second end 1052 of the side strip 105 of the main curtain, and the linkage structure 501 of the corner curtain. The first pulley 406 and the first pulley 402 are located at the top and bottom of the rear guide rail assembly 104, respectively. The second pulley 407 is located at the top of the front guide rail assembly 103. That is, the main curtain 101 and the corner curtain 201 share the second drive line 405. When the motor 301 is working, it can drive the first thread pulley 402 and the second thread pulley 403 to rotate through the gear 302 and the transmission shaft 401. When the first thread pulley 402 and the second thread pulley 403 rotate, they drive the first transmission line 404 to rotate around the first pulley 406 and the second transmission line 403 to rotate around the second pulley 407, so as to drive the main window curtain 101 to open and close.

[0056] (3) Linkage group 500, including the linkage structure 501 and slider 502 of the corner window curtain.

[0057] like Figure 4 As shown, the linkage structure 501 can be connected to the edge strip 204 of the corner window curtain, and the slider 502 is connected to the second transmission line 405. When the second transmission line 405 rotates, it can drive the slider 502 to move closer to or away from the linkage structure 501 of the corner window curtain, thereby driving the corner window curtain 201 and the main window curtain 101 to open or close in a linkage manner.

[0058] For example, a magnified view of the impact location of the linkage structure 501 can be shown as follows: Figure 7a As shown, a partial enlarged view of the position of the impact linkage structure 501 of the slider 502 can be seen as follows. Figure 7bAs shown. During the unfolding of the main curtain 101 driven by the second transmission line 405, when the slider 502 strikes the linkage structure 501 of the corner curtain, the second transmission line 405, the linkage structure 501, and the slider 502 drive the corner curtain 201 to unfold, and the main curtain 101 and the corner curtain 201 simultaneously reach their stop positions. Alternatively, for example, during the closing of the main curtain 101 driven by the second transmission line 405, the main curtain 101 and the corner curtain 201 close simultaneously. When the corner curtain 201 is fully closed, the second transmission line 405 drives the slider 502 away from the linkage structure 501, and then the second transmission line 405 drives the main curtain 101 to close independently until the main curtain 101 is fully closed.

[0059] Furthermore, considering that the deployment of the second transmission line 405 is more complex than that of the first transmission line 404, in an optional embodiment, the transmission assembly 400 may further include a conduit 410. For example... Figures 3-6 The conduit 410 can be installed on a vehicle door, for example, to accommodate the second drive line 405. When the second drive line 405 rotates around the second pulley 407, it can move within the conduit 410, thereby protecting the movement tendency of the second drive line 405. Of course, in optional embodiments, a conduit can also be provided for the first drive line 404; this application does not specifically limit this.

[0060] In another optional embodiment, the transmission assembly 400 may further include a third pulley 408 and a fourth pulley 409. For example... Figure 6 As shown, the third pulley 408 can be located at the bottom of the front guide rail assembly 103, the fourth pulley 409 is located at the rear (end) of the corner window guide rail assembly, and the second transmission line 405 can run around the bottom of the third pulley 408 and the top of the fourth pulley 409.

[0061] It should be understood that the above text combines... Figures 3-7b The structure described is merely an example and does not constitute any limitation. In specific implementations, the structure of the linkage drive device can be flexibly adjusted according to vehicle model or requirements, and the embodiments in this application do not impose specific limitations.

[0062] The working principle of the above-mentioned linkage drive device is described below with reference to the accompanying drawings.

[0063] In this embodiment, at the same time, the first transmission line 404 and the second transmission line 405 rotate in opposite directions around the first pulley 406 and the second pulley 407, respectively. In an optional embodiment, at the same time, the second transmission line 405 rotates in opposite directions around the third pulley 408 and the fourth pulley 409.

[0064] Taking the left rear door window of the vehicle as an example, different dashed arrows represent the directions of movement of the first transmission line 404 and the second transmission line 405, respectively. Figure 8 As shown, during the process of the main curtain 101 being moved upward and unfolded by the second transmission line 405, the first transmission line 404 rotates counterclockwise around the first pulley 406, and the second transmission line 405 rotates clockwise around the second pulley 407. Initially, the first transmission line 404 and the second transmission line 405 only move the edge strip 105 of the main curtain upward, thereby gradually unfolding the main curtain 101. When the second transmission line 405 moves to a certain set position (the starting position of the corner curtain 201), the slider 502 on the second transmission line 405 will collide with the linkage structure 501 of the corner curtain. Afterwards, under the push of the second transmission line 405 and the slider 502, the linkage structure 501 will drive the edge strip 204 of the corner curtain (see...) Figure 4 As shown, the curtain moves backward (to the left in the diagram, gradually approaching the rear of the vehicle), causing the corner curtain 201 to rotate out from the corner curtain roller assembly 202 and gradually unfold along the corner window guide rail assembly 203, so that the side strips 105 and 204 of the main curtain reach their respective stops at the same time. During the unfolding of the main curtain 101 driven by the first transmission line 404 and the second transmission line 405, the second transmission line 405 rotates clockwise around the third pulley 408 and counterclockwise around the fourth pulley 409.

[0065] Figure 8 The linkage drive process can also be described as follows: when the slider 502 strikes the linkage structure 501 of the corner curtain, the second transmission line 405, the linkage structure 501, and the slider 502 drive the corner curtain to unfold, so that the side strip 105 of the main curtain and the side strip 204 of the corner curtain reach their respective stops at the same time. The stop of the side strip 105 of the main curtain can be located at the (longitudinal) top of the front guide rail group 103 and the rear guide rail group 104, and the stop of the side strip 204 of the corner curtain can be located at the (lateral) end of the corner guide rail group 203 (near the rear of the vehicle).

[0066] Or for example Figure 9As shown, during the process of the main window curtain 101 being closed by the second transmission line 405, the first transmission line 404 rotates clockwise around the first pulley 406, and the second transmission line 405 rotates counterclockwise around the second pulley 407. Initially, the first transmission line 404 and the second transmission line 405 drive the side strip 105 of the main window curtain downwards, while the second transmission line 405, the linkage structure 501, and the slider 502 drive the side strip 204 of the corner window curtain forward (to the right in the figure, closer to the front of the vehicle), thereby gradually closing the main window curtain 101 and the corner window curtain 201. When the second transmission line 405, the linkage structure 501, and the slider 502 drive the side strip 204 of the corner window curtain to the starting position of the linkage structure 501, the corner window curtain 201 is completely housed within the corner window curtain roller assembly 202. Subsequently, the second transmission line 405 drives the slider 502 away from the linkage structure 501. Driven by the first transmission line 404 and the second transmission line 405, the main curtain 101 continues to move longitudinally downwards along the front guide rail group 103 and the rear guide rail group 104 until the main curtain 101 is completely closed in the main curtain roller group 102. During the process of the first transmission line 404 and the second transmission line 405 driving the main curtain 101 to close, the second transmission line 405 rotates counterclockwise around the third pulley 408 and clockwise around the fourth pulley 409.

[0067] It should be understood that, in the embodiments of this application, if the aforementioned side window is the right-side door window of the vehicle, the structure of the corresponding linkage drive device is related to... Figures 2-9 The structure is symmetrically designed, and the movement trends of the first and second drive lines are opposite. For example, if the aforementioned side window is the right-side door window of the vehicle, during the process of the first and second drive lines driving the main window curtain to unfold, the first drive line rotates clockwise around the first pulley, and the second drive line rotates counterclockwise around the second pulley, counterclockwise around the third pulley, and clockwise around the fourth pulley. Conversely, during the process of the first and second drive lines driving the main window curtain to close, the first drive line rotates counterclockwise around the first pulley, and the second drive line rotates clockwise around the second pulley, clockwise around the third pulley, and counterclockwise around the fourth pulley. For specific details of the linkage drive mechanism of the sunshade of the right-side door window of the vehicle, please refer to the above description. Figures 2-9 The relevant information will not be repeated here.

[0068] Based on the above description, this application embodiment also provides a vehicle that may include a side window sunshade and a linkage drive device as described above. Optionally, the vehicle may further include an end cap for fixing the main curtain roller assembly of the side window sunshade inside the outer tube assembly, the end cap being located at the edge of the outer tube assembly.

[0069] It should be understood that the vehicles in the embodiments of this application may include at least one of new energy vehicles, hybrid vehicles, range-extended electric vehicles, or fuel vehicles, and the embodiments of this application do not specifically limit them.

[0070] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
