Description

Technical Field

[0002] In existing motor vehicles, the side windows in the body are designed to match the body shape to form liftable side windows and fixed triangular windows behind the side windows. Since the front and rear ends of the side windows and the triangular windows are unequal in size, and in order to provide a proper sunshade function for the side windows and the triangular windows behind them, side window sunshades are installed at the side windows, and triangular window sunshades are installed at the triangular windows behind the side windows.

[0003] Generally speaking, the existing electric side window sunshade is composed of a curtain reel group, side curtains connected to the curtain reel group, a support rod connected to a movable side plate of the side curtains, and an electric drive mechanism that can drive the support rod to rise and fall. The curtain reel group is transversely arranged in the side door of the vehicle body, and the side curtains can be automatically rolled up inside by the curtain reel group. The support rod can be operated by the electric drive mechanism to push the movable side plate of the side curtain upward from the side door to rise, and pull the side curtain to unfold upward from the curtain reel group. When the support rod is lowered by the electric drive mechanism, the movable side plate of the side curtain connected to the upper end of the support rod descends along with the support rod, and the side curtain can be automatically rolled up and folded by the curtain reel group.

[0004] As for the composition structure of the existing electric triangular window sunshade, it includes a transverse guide assembly, a curtain roller group, a curtain connected to the curtain roller group and a pull-wire drive assembly. The transverse guide assembly includes a transverse guide rail and a rocker arm. The transverse guide rail is installed below the triangular window. The curtain roller group is longitudinally arranged on the front side of the transverse guide rail. The upper end of the rocker arm is connected to the movable side strip of the curtain, and the lower end of the rocker arm is connected to the slider located in the transverse guide rail. The pull-wire drive assembly is connected to the slider with its pull wire to drive the slider to move along the transverse guide rail, and operates the movable side strip of the curtain through the rocker arm provided on the slider. Combined with the curtain being automatically rolled up by the curtain roller group, the rocker arm can be operated to move laterally and drive the curtain to unfold backward from the curtain roller group.

[0005] Although the aforementioned side window sunshade and the rear triangular window sunshade can be installed on the side window and the rear triangular window of the motor vehicle to provide sunshade functions, the existing side window sunshade and the rear triangular window sunshade have independent overall components and cannot be linked, and must be operated separately.

[0082] The following is a technical solution adopted by the present invention to achieve the predetermined purpose of the invention, which is further described with reference to the embodiments of the present invention disclosed in conjunction with the accompanying drawings of the specification.

[0083] like Figure 1 As shown, it discloses an embodiment of the linked driving mechanism 3 of the side window sunshade 1 and the triangular window sunshade 2 of the present invention. The linked driving mechanism 3 is installed in the body of a motor vehicle, and connects the side window sunshade 1 located on the side window of the vehicle body and the triangular window sunshade 2 located on the triangular window behind the side window, so that the side window sunshade 1 and the triangular window sunshade 2 can be synchronously unfolded and synchronously folded.

[0084] like Figure 1 As shown, the side window sunshade 1 comprises a curtain reel assembly 10, a side curtain fabric 11 and a support rod 12. The curtain reel assembly 10 is transversely arranged in the side door of the vehicle body. The side curtain fabric 11 is connected to the curtain reel assembly 10. The side curtain fabric 11 can be automatically rolled up by the curtain reel assembly 10. The upper end of the support rod 12 is connected to the movable side plate 111 of the side curtain fabric 11. The support rod 12 can be operated to drive the side curtain fabric 11 to unfold upward from the curtain reel assembly 10. The side window sunshade 1 belongs to the prior art, and its specific structure is not repeated here.

[0085] like Figure 1 and Figures 6 to 8As shown, the triangular window sunshade 2 includes a transverse guide assembly 20, a curtain roller group 21 and a curtain 22. The transverse guide assembly 20 includes a transverse guide rail 201 and a rocker arm 202. The transverse guide rail 201 is installed below the triangular window and adjacent to the rear end of the curtain roller group 10 of the side window sunshade 1. The curtain roller group 21 is longitudinally arranged between the side window and the triangular window. The curtain 22 is connected to the curtain roller group 21. The lower end of the rocker arm 202 is pivotally connected to a slider 203. The slider 203 is installed in the transverse guide rail 201 and can be operated to move along the transverse guide rail 201. The curtain 22 can be automatically rolled up by the curtain roller group 21. The upper end of the rocker arm 202 is pivotally connected to the movable side strip 221 of the curtain 22. The rocker arm 202 can be operated to move laterally and drive the curtain to unfold backward from the curtain roller group 21. The triangular window sunshade 2 belongs to the prior art, and its specific structure is not described here.

[0086] like Figure 1 , Figure 3 , Figure 6 , Figure 7 and Fig.10 As shown, the linkage drive mechanism 3 of the present invention comprises a guide tube 30, a flexible transmission assembly 40, a clutch transmission assembly 50 and a drive assembly 60. The specific structure is described as follows:

[0087] like Figure 1 and Figure 3 As shown, the conduit 30 can be longitudinally installed in the vehicle body and is located below the curtain fabric reel assembly 10 of the side window sunshade 1, and the support rod 12 can move up and down in the conduit 30. In this embodiment, a first steering member 31 and a second steering member 32 are also arranged at intervals at the upper end of the conduit 30. The height position of the first steering member 31 is higher than the height position of the second steering member 32. Preferably, the first steering member 31 and the second steering member 32 are pulleys.

[0088] like Figure 1 , Figure 3 and Figure 4 As shown, the flexible transmission assembly 40 includes a support rod driving member 41, a first transmission line 42 and a second transmission line 43. The support rod driving member 41 is installed in the catheter 30 and connected to the bottom end of the support rod 12. The support rod driving member 41 and the support rod 12 are operated to move up and down together.

[0089] like Figure 3 and Figure 4As shown, the first transmission line 42 and the second transmission line 43 are both flexible wires that can bend and have no elasticity, wherein one end of the first transmission line 42 is directly or indirectly connected to the support rod driving member 41, and the other end of the first transmission line 42 can extend out of the lower end of the conduit 30, one end of the second transmission line 43 extends into the conduit 30 and is directly or indirectly connected to the support rod driving member 41, the second transmission line 43 bypasses the first steering member 31, and passes through the transverse guide rail 201 of the triangular window sunshade 2, and then turns through the rear end of the transverse guide rail 201 to extend forward and bypass the second steering member 32 and then extends downward through the inside of the conduit 30.

[0090] like Figures 1 to 3 As shown, a transmission line guide 44 can be further provided at the bottom of the curtain reel assembly 10 between the conduit 30 and the transverse guide rail 201 , and the second transmission line 43 bypasses the first deflection member 31 , passes through the transmission line guide 44 , and then penetrates into the transverse guide rail 201 of the triangular window sunshade 2 .

[0091] like Figure 3 and Figure 4 As shown, when one end of the first transmission line 42 is indirectly connected to the support rod driving member 41, a first terminal connection member 412 is provided at the end of the first transmission line 42, and the first terminal connection member 412 is movably installed inside the support rod driving member 41, and a first elastic member 411 is provided between the first terminal connection member 412 and the support rod driving member 41. The first transmission line 42 is indirectly connected to the support rod driving member 41 through the first terminal connection member 412 and the first elastic member 411, and buffer elasticity is provided between the first transmission line 42 and the support rod driving member 41 through the first elastic member 411. Similarly, when one end of the second transmission line 43 is indirectly connected to the clutch transmission member 52, a second terminal 414 is provided at the end of the second transmission line 43, and the second terminal 414 is movably installed inside the support rod driving member 41, and a second elastic member 413 is provided between the second terminal 414 and the support rod driving member 41. The second transmission line 43 is indirectly connected to the support rod driving member 41 through the second terminal 414 and the second elastic member 413, and the second elastic member 413 provides buffer elasticity between the second transmission line 43 and the support rod driving member 41. At the same time, the first transmission line 42 and the second transmission line 43 are connected to the support rod driving member 41 through the first elastic member 411 and the second elastic member 413 respectively, and provide elastic force, thereby maintaining the first transmission line 42 and the second transmission line 43 in a tensioned state, so as to facilitate the transmission of the first transmission line 42 and the second transmission line 43.

[0092] like Figure 3 and Figure 4As shown, it is further explained that the direction in which the first transmission line 42 exerts force on the support rod driving member 41 is opposite to the direction in which the second transmission line 43 exerts force on the support rod driving member 41, so the first elastic member 411 and the second elastic member 413 provide the support rod driving member 41 with buffering elastic forces in opposite directions. In this embodiment, the first elastic member 411 and the second elastic member 413 can be compression springs, and are respectively sleeved on the ends of the first transmission line 42 and the ends of the second transmission line 43.

[0093] like Figures 6 to 8 As shown, the clutch transmission assembly 50 is connected to the second transmission line 43, and the clutch transmission assembly 50 can be clutched and linked with the slider 203 at the bottom end of the rocker arm 202 of the triangular window sunshade 2, and compensate for the distance difference between the front and rear movement stroke of the rocker arm 202 and the up and down movement stroke of the support rod 12. Among them, the length of the side window of the motor vehicle in the height direction is longer, and the length of the triangular window in the front and rear direction is shorter, that is, the up and down movement stroke of the support rod 12 to drive the side curtain cloth 11 to be unfolded and folded is greater than the lateral movement stroke of the slider 203 at the bottom end of the rocker arm 202 to drive the cloth curtain 22 to be unfolded and folded. Therefore, the clutch transmission member 52 can be relatively clutched with the elastic fastener 51 to compensate for the distance difference between the forward and backward movement stroke of the slider 203 at the lower end of the rocker arm 202 in the transverse guide rail 201 and the up and down movement stroke of the support rod 12, so that the side curtain cloth 11 of the side window sunshade 1 and the cloth curtain 22 of the triangular window sunshade 2 can be linked to unfold and fold.

[0094] like Figures 6 to 8 As shown, in this embodiment, the clutch transmission assembly 50 includes an elastic fastener 51 and a clutch transmission member 52. The elastic fastener 51 can be installed in the slider 203 of the triangular window sunshade 2 and move together with the rocker arm 202. The clutch transmission member 52 is connected to the second transmission line 43 and can be operated through the second transmission line 43 to enter and exit the transverse guide rail 201 through the front end of the transverse guide rail 201 of the triangular window sunshade 2. The clutch transmission member 52 can be operated to be relatively clutched with the elastic fastener 51. When the clutch transmission member 52 enters the interior of the transverse guide rail 201 from the front end of the transverse guide rail 201, the clutch transmission member 52 is fastened by the elastic fastener 51 and moves in conjunction; when the clutch transmission member 52 moves out of the transverse guide rail 201 from the front end of the transverse guide rail 201, the clutch transmission member 52 can be separated from the elastic fastener 51.

[0095] like Figures 6 to 8As shown, in this embodiment, the slider 203 has an active space 204, the elastic fastener 51 has a spring portion 511 and a hook 512, one end of the spring portion 511 is fixed in the slider 203, the other end of the spring portion 511 is a free end, the hook 512 is arranged at the free end of the spring portion 511 and is located in the active space 204 of the slider 203. The clutch transmission member 52 has a first end 521, a second end 522 and a buckle groove 523 located between the first end 521 and the second end 522, the hook 512 of the elastic fastener 51 can be buckled in the buckle groove 523 of the clutch transmission member 52, so that the clutch transmission member 52 and the slider 203 are linked together, and the clutch transmission member 52 can be operated to be separated from the hook 512 of the elastic fastener 51.

[0096] like Figures 6 to 8 As shown, in the triangular window sunshade 2, the rear end of the transverse guide rail 201 has a steering component 206, and the front end of the transverse guide rail 201 has a guide component 205, and the guide component 205 has a transverse through hole connected to the internal space of the transverse guide rail 201 and a rear end wall located at the rear end periphery of the transverse through hole. After the second transmission line 43 passes through the transverse through hole of the guide component 205 at the front end of the transverse guide rail 201, it passes through the interior of the transverse guide rail 201 and the slider 203, bypasses the steering component 206 at the rear end of the transverse guide rail 201, and then extends forward and bypasses the second steering member 32 and then extends downward through the interior of the conduit 30. The clutch transmission member 52 can be driven by the second transmission line 43 to pass through the transverse through hole in the guide component 205, and is connected by being snapped into the elastic fastener 51 provided on the slider 203.
