Since the embodiments disclosed in the present disclosure can be arranged in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations.

[0033] Figure 1 A schematic diagram of a motor vehicle 100 according to an embodiment of the present disclosure is shown. The motor vehicle 100 includes an electric sunshade device 110. The electric sunshade device 110 is configured to provide sunshade for side windows 130 of rear seats of the motor vehicle 100.

[0034] Figure 2A and Figure 2B The specific structure of the electric sunshade device 110 is shown, wherein Figure 2A is a stereoscopic diagram of the electric sunshade device 110 from a first viewing angle, Figure 2B It is a perspective view of the electric sunshade device 110 from a second viewing angle. The electric sunshade device 110 includes a sunshade 220, a sunshade storage box 250, a power system 200, a guide structure 280 and a support frame 290.

[0035] The sunshade 220 is made of a light-shielding material and is flexible. When sunshade is not needed, most or all of the sunshade 220 is stored in the sunshade storage box 250; when sunshade is needed, the sunshade 220 can be extended from the sunshade storage box 250 under the drive of the power system 200, thereby shielding at least a part of the side window 130, as described later.

[0036] By storing the sunshade 220 in the sunshade storage box 250, for example, winding it on a reel (not shown) in the sunshade storage box 250, space can be saved, and the sunshade 220 can be stored evenly and neatly, so that the sunshade 220 can be smoothly extended next time. An elastic element (not shown), such as a spiral torsion spring, is also provided in the sunshade storage box 250, and the reel is connected to the elastic element. The elastic element is used to provide a driving force to rotate the reel in the direction of retracting the sunshade 220, so as to tighten and / or retract the sunshade 220.

[0037] Continue to refer to Figure 2A and Figure 2BThe sunshade curtain 220 has a first side 221 and a second side 222 opposite to each other in the width direction W, and an outer end 223 and an inner end (not shown) opposite to each other in the length direction, wherein when the sunshade curtain 220 is extended from the sunshade curtain storage box 250, the outer end 223 is the end away from the sunshade curtain storage box 250, and the inner end is always connected to the roller in the sunshade curtain storage box 250.

[0038] The support frame 290 includes a first side support frame 291 and a second side support member 292 , which are respectively located on the first side 221 and the second side 222 of the sunshade 220 and are respectively connected to the sunshade storage box 250 .

[0039] The power system 200 includes an actuator 210, a synchronization shaft 230, a first side transmission device 260, and a second side transmission device 270. The actuator 210 is located at the first side 221 of the sunshade 220, and is used to output power to move the sunshade 220, as described later. The first side transmission device 260 and the second side transmission device 270 are respectively arranged on the first side 221 and the second side 222 of the sunshade 220, and the synchronization shaft 230 extends from the first side 221 to the second side 222 of the sunshade 220. The first side transmission device 260 is connected to the actuator 210 and is configured to receive a part of the power output by the actuator 210, and the second side transmission device 270 is connected to the actuator 210 via the synchronization shaft 230, and is configured to receive another part of the power output by the actuator 210.

[0040] The first side transmission device 260 and the second side transmission device 270 are respectively connected to the first side 221 and the second side 222 of the sunshade curtain 220. For example, the first side transmission device 260 and the second side transmission device 270 are respectively connected to the outer end 223 of the sunshade curtain 220, so that the first side 221 and the second side 222 of the sunshade curtain 220 can move synchronously driven by the first side transmission device 260 and the second side transmission device 270, so that the movement of the sunshade curtain 220 is smoother and more accurate, which is especially important for the flexible sunshade curtain 220.

[0041] Combine the following FIG. 2A to FIG. 8B The specific structures of the power system 200 and its execution device 210 are described in detail. Figure 3 and Figure 4 Two partial structures of the power system 200 are shown, wherein Figure 3 The connection relationship between the actuator 210, the first side transmission device 260 and the synchronization shaft 230 is shown. Figure 4 The connection relationship between the second side transmission device 270 and the synchronization shaft 230 is shown. For ease of observation, Figure 3 The actuator housing 240 and the related connecting bolts of the actuator 210 are removed, and only a part of the first output worm 261 is intercepted. Figure 4 A portion of the transmission housing 273 of the second side transmission 270 and the related connecting bolts are removed, and only a portion of the second output worm 271 is cut out. Figure 5 shows a perspective view of the synchronization shaft 230, Figure 6 shows a perspective view of an actuator device 210, Figure 7 An exploded view of the actuator housing 240 of the actuator device 210 is shown, Fig. 8A A perspective view of a first half housing 650 of the actuator housing 240 is shown, Figure 8B A perspective view of a second housing half 660 of the actuator housing 240 is shown.

[0042] Reference Figures 2A to 3 The actuator 210 includes a motor 380 , a transmission assembly 390 , an input worm 320 , an input worm gear 330 , a first output worm gear 360 , an input bevel gear 340 , an output bevel gear 350 , an output shaft 370 and an actuator housing 240 .

[0043] The motor 380 is a power source of the power system 200. The input worm 320 is connected to the motor 380 through the transmission assembly 390 to receive the torque output by the motor 380. The input worm wheel 330 is meshed with the input worm 320 to obtain a required transmission ratio.

[0044] The first output worm gear 360 is coaxially connected to the input worm gear 330 and is configured to rotate synchronously with the input worm gear 330. For example, the input worm gear 330 and the first output worm gear 360 are respectively fixedly connected to the same gear shaft 310, so that the first output worm gear 360 is driven by the input worm gear 330 via the gear shaft 310, so that the first output worm gear 360 and the input worm gear 330 rotate synchronously around the gear shaft axis 311. The input worm gear 330 can be detachably mounted on the gear shaft 310 through a key connection, or the input worm gear 330 and the gear shaft 310 are integral parts. The first output worm gear 360 can be detachably mounted on the gear shaft 310 through a key connection, or the first output worm gear 360 and the gear shaft 310 are integral parts.

[0045] Continue to refer to Figures 2A to 3 The first side transmission device 260 includes a first output worm 261, which is located at the first side 221 of the sunshade curtain 220 and connected to the first side 221 of the sunshade curtain 220 via the outer end 223 of the sunshade curtain 220. The first output worm 261 is meshed with the first output worm gear 360, so as to transmit the power output by the first output worm gear 360 to the first side 221 of the sunshade curtain 220.

[0046] Reference Figure 3The input bevel gear 340 is coaxially connected to the input worm gear 330 and is configured to rotate synchronously with the input worm gear 330. For example, the input bevel gear 340 is also fixedly connected to the gear shaft 310, so that the input bevel gear 340 is driven by the input worm gear 330 via the gear shaft 310, so that the input bevel gear 340 and the input worm gear 330 rotate synchronously around the gear shaft axis 311. The input bevel gear 340 can be detachably mounted on the gear shaft 310 through a key connection, or the input bevel gear 340 can be an integral part with the gear shaft 310.

[0047] Reference Figures 3 to 6 The output bevel gear 350 is meshed with the input bevel gear 340, and the output shaft 370 is coaxially connected to the output bevel gear 350 and is configured to rotate around the output axis 371 synchronously with the output bevel gear 350, thereby transmitting the rotational motion and torque output by the gear output end 351 of the output bevel gear 350. The synchronizing shaft 230 is coaxially connected to the output shaft 370 and is configured to rotate around the output axis 371 synchronously with the output shaft 370, thereby transmitting the power output by the output bevel gear 350.

[0048] For example, the output shaft 370 includes an output end 620 for connecting to the synchronous shaft 230, and the output end 620 includes an output end connection structure, for example, the output end connection structure is a groove 621 extending along the output axis 371, and the cross section of the groove 621 perpendicular to the output axis 371 is a non-circular shape, for example, the groove 621 is an internal spline. The synchronous shaft 230 has a first end 231 and a second end 232 opposite to each other in the length direction, and the first end 231 has a synchronous shaft connection structure, for example, the synchronous shaft connection structure is a protrusion 510 extending along the synchronous shaft axis 233, and the cross section of the protrusion 510 perpendicular to the synchronous shaft axis 233 is a non-circular shape, for example, the protrusion 510 is an external spline matched with the groove 621. Therefore, by inserting the protrusion 510 into the groove 621, the synchronous shaft 230 can be quickly connected to the output shaft 370, and the synchronous shaft 230 and the output shaft 370 can rotate synchronously.

[0049] It is worth noting that although in the illustrated embodiment, the groove 621 is an internal spline and the protrusion 510 is an external spline that matches the groove 621, in other embodiments, the cross-section of the groove 621 can be other non-circular shapes, the cross-section of the protrusion 510 can be other non-circular shapes, and the cross-section shape of the groove 621 can be different from the cross-section shape of the protrusion 510. It is only necessary to enable the protrusion 510 to be inserted into the groove 621 and to enable at least a portion of the non-cylindrical outer surface of the protrusion 510 to match with at least a portion of the non-cylindrical inner surface of the groove 621, so that the synchronizing shaft 230 and the output shaft 370 can rotate synchronously.

[0050] In addition, although in the illustrated embodiment, the synchronization shaft 230 is connected to the output bevel gear 350 via the output shaft 370, in other embodiments, the synchronization shaft 230 can be directly connected to the gear output end 351 of the output bevel gear 350, for example, the synchronization shaft 230 is detachably connected to the output bevel gear 350 by a key connection.

[0051] Reference Figures 2A to 4 The second side transmission device 270 includes a second output worm gear 272, a second output worm 271 and a transmission device housing 273. The second output worm gear 272 is coaxially connected to the synchronization shaft 230 and is configured to rotate synchronously with the synchronization shaft 230 around the output axis 371. For example, the second output worm gear 272 is connected to the second end 232 of the synchronization shaft 230 through a spline structure 410. The second output worm 271 is disposed on the second side 222 of the sunshade curtain 220 and is connected to the second side 222 of the sunshade curtain 220 via the outer end 223 of the sunshade curtain 220. The second output worm 271 is meshed with the second output worm gear 272, so as to transmit the power output from the output bevel gear 350 transmitted via the synchronization shaft 230 to the second side 222 of the sunshade curtain 220. The first output worm 261 and the second output worm 271 extend substantially parallel to each other, thereby synchronously driving the first side 221 and the second side 222 of the sunshade 220 to move.

[0052] The second output worm gear 272 is installed in the transmission housing 273, the second output worm 271 is inserted into the transmission housing 273, and the transmission housing 273 is connected to the second side support frame 292 by connecting bolts 293.

The actuator housing 240 is connected to the first side support frame 291 and the sunshade storage box 250 by connecting bolts 293.

[0054] Reference Figures 6 to 8BThe actuator housing 240 is a split structure, including a first half housing 650 and a second half housing 660 detachably connected by connecting bolts 640, so as to facilitate the installation of components inside the actuator housing 240. The split surface 651 of the first half housing 650 and the split surface 661 of the second half housing 660 are respectively substantially perpendicular to the gear shaft axis 311, that is, the first half housing 650 and the second half housing 660 are respectively located on both sides of the axial direction of the gear shaft 310, and are respectively located on both sides of the motor axis 381 of the motor 380 (that is, the axis of the output shaft of the motor 380).

[0055] The actuator housing 240 has a first opening 610 and a second opening 630. The first opening 610 is used to expose the plurality of teeth 361 of the first output worm gear 360, so as to allow the first output worm 261 to be inserted into the actuator housing 240 through the first opening 610 and to mesh with the first output worm gear 360. The second opening 630 is used to expose the output end 620, so as to allow the output end 620 to be connected to the synchronization shaft 230.

[0056] The actuator housing 240 further includes a motor positioning portion configured to support and position the motor 380. For example, the first half housing 650 includes a first half hole 851, and the second half housing 660 includes a second half hole 861. The first half hole 851 and the second half hole 861 enclose a chamber for accommodating the motor 380. At least part of the inner wall of the first half hole 851 and the second half hole 861 cooperates with the outer surface of the motor 380, thereby supporting and positioning the motor 380.

[0057] The actuator housing 240 further includes a gear shaft positioning portion, which is configured to support and position the gear shaft 310. For example, the first half housing 650 includes a first positioning hole 852, and the second half housing 660 includes a second positioning hole 862, and the first positioning hole 852 and the second positioning hole 862 are respectively matched with two opposite ends of the gear shaft 310 in the axial direction, so as to support and position the gear shaft 310.

[0058] The actuator housing 240 further includes an output shaft positioning portion configured to support and position the output shaft 370. For example, the actuator housing 240 includes an output shaft positioning hole 710 configured to cooperate with at least a portion of the outer circumference of the output shaft 370, thereby supporting and positioning the output shaft 370. One end of the output shaft positioning hole 710 provides a second opening 630.

[0059] Reference Figure 2A and 2B, two guide structures 280 are respectively arranged on the first side support frame 291 and the second side support member 292. The two guide structures 280 are used to guide and support the first output worm 261 and the second output worm 271 respectively. For example, the guide structure 280 is a guide groove, and the first output worm 261 and the second output worm 271 are respectively inserted into the corresponding guide groove and are configured to move substantially along the extension direction of the guide groove. Since the shape of the side window 130 of the motor vehicle 100 is generally a curved surface, the first output worm 261 and the second output worm 271 are configured to be bendable at least in part of their length, and at least a part of the guide groove extends in a curved manner and is substantially parallel to the curved surface of the side window 130, so as to guide the first output worm 261 and the second output worm 271 to drive the sunshade 220 to move along a curved path substantially parallel to the curved surface of the side window 130, so that the sunshade 220 better matches the shape of the side window 130.

[0060] According to the embodiment of the present disclosure, at least a portion of the electric sunshade device 110, such as the sunshade storage box 250, the power system 200, the support frame 290, etc., is accommodated inside the door 140 of the motor vehicle 100, that is, in the space between the inner door panel and the outer door panel of the door 140, so as to save space and improve aesthetics.
