Vehicle sunroof sunshade curtain device

Abstract

The utility model discloses a vehicle sunroof sunshade curtain device. The vehicle skylight sunshade device comprises a frame, a driving assembly, a reel assembly, a transmission shaft connected between the driving assembly and the reel assembly, a first pull rope, a second pull rope and a supporting plate. The frame is provided with a first mounting seat. The reel assembly is disposed on the frame and includes a driving end and a driven end. The first pull rope is suitable for being wound on the driving end or released from the driving end, and the second pull rope is suitable for being wound on the driven end or released from the driven end. The supporting plate extends in the vertical direction and is provided with a receiving opening corresponding to the first mounting base. The driving end of the reel assembly is rotatably kept in the receiving opening. When the first pull rope exerts pulling force on the driving end of the reel assembly, the supporting plate bears part of the pulling force. Therefore, the tensile force borne by the driving assembly is reduced, the radial load borne by the driving assembly is reduced, and the adverse effect of the large radial load on the driving assembly is avoided.

Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a vehicle sunroof sunshade device. Background Art

[0002] Some vehicles are equipped with sunroofs, even panoramic sunroofs, to increase the light entering the vehicle and improve the field of vision of the vehicle occupants. However, in an environment with strong sunlight, the sunroof needs to be covered to reduce the light entering the vehicle.

[0003] A sunshade device can be installed at the skylight to block light. The sunshade device generally includes components such as a curtain, a reel assembly, a pull cord, and a motor. The curtain is wound on the reel assembly and includes a free end. One end of the pull cord is connected to the end of the reel assembly, and the other end is connected to the free end of the curtain. The motor is connected to the end of the reel assembly through a drive shaft. In this way, the motor drives the reel assembly to rotate and drives the pull cord to move, so that the curtain is unwound from the reel and unfolded to block the skylight, or the curtain is wound onto the reel to reveal the skylight. However, when using this sunshade device, the end of the reel assembly needs to bear the tension of the pull cord, and the drive shaft will transmit the tension to the motor and cause the motor to bear a large radial load, which will have an adverse effect on the motor.

[0080] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the specific embodiments of this application and the corresponding drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0081] Figure 1 A vehicle 1 according to an embodiment of the present application is schematically shown. Figure 1 As shown, a skylight opening 11 is provided on the roof panel 12 of the vehicle 1, and a skylight glass 13 (as shown in FIG. Figure 6 As shown). In order to shield the sunroof glass 13 when necessary, a vehicle sunroof sunshade device 2 (hereinafter referred to as sunshade device 2) is also installed at the sunroof opening 11. For example, Figure 6 As shown, the sunshade device 2 is located in a space between the sunroof glass 13 and the roof panel 12 , generally along a vertical direction Z that is parallel to the height direction of the vehicle (ie, the vertical direction Z is generally perpendicular to the roof panel 12 ).

[0082] Next, the sunshade device 2 will be described.

[0083] like Figure 2 As shown, the sunshade device 2 mainly includes a frame 3, a driving assembly 4, a roller assembly 5, a curtain 201 and two guide rails 202.

[0084] The frame 3 is configured as a strip extending in a first direction X. Two guide rails 202 are connected to each end of the frame 3 and extend forward in a second direction Y that is substantially perpendicular to the first direction X. For example, the first direction X is substantially the width of the vehicle, and the second direction Y is substantially the longitudinal direction of the vehicle. A vertical direction Z is substantially perpendicular to the first and second directions X, Y.

[0085] The drive assembly 4 and the reel assembly 5 are both mounted on the frame 3, and the drive assembly 4 and the reel assembly 5 are connected via a transmission shaft 6 (eg Figure 4b As shown in FIG), the drive assembly 4 can drive the reel assembly 5 to rotate. In one embodiment, the reel assembly 5 includes an active end 501 and a driven end 502 (as shown in FIG). Figure 11 The transmission shaft 6 extends along the first direction X and includes a first connecting section 61 and a second connecting section 62 opposite to each other (as shown). Figure 10 The first connecting section 61 is connected to the active end 501 of the reel assembly 5 , and the second connecting section 62 is connected to the driving assembly 4 .

[0086] Also like Figure 3 As shown, at least a portion of the curtain 201 is wound around the reel assembly 5 and has a free edge 205. A tensioning member 207 is disposed at the free edge 205 to stretch the curtain 201 along the first direction X. The sunshade device 2 also includes two pull cords (i.e., a first pull cord 204a and a second pull cord 204b) extending generally along the second direction Y and two pulley sets (i.e., a first pulley set 206a and a second pulley set 206b). The first pull cord 204a and the second pull cord 204b extend along the two guide rails 202, respectively. The first pull cord 204a is connected to a first end of the tensioning member 207 and is redirected by the first pulley set 206a before being connected to the driving end 501 of the reel assembly 5. The second pull cord 204b is connected to a second end of the tensioning member 207 and is redirected by the second pulley set 206b before being connected to the driven end 502 of the reel assembly 5. Thus, when the drive assembly 4 drives the reel assembly 5 to rotate in a first direction (e.g., clockwise), the two pull cords move rearward along the two guide rails 202 (i.e., in the direction toward the reel assembly 5 in the second direction Y) and are wound onto the reel assembly 5. The free edge 205 of the curtain 201 is pulled by the two pull cords, released from the reel assembly 5, and moves forward along the two guide rails 202 (i.e., in the direction away from the reel assembly 5 in the second direction Y). In this way, the curtain 201 is released from the reel assembly 5 and covers the sunroof glass. When the drive assembly 4 drives the reel assembly 5 to rotate in a second direction (e.g., counterclockwise), the two pull cords move forward along the two guide rails 202 and are released from the reel assembly 5. The free edge 205 of the curtain 201 moves rearward along the two guide rails 202 toward the reel assembly 5, thereby winding the curtain 201 onto the reel assembly 5 to reveal the sunroof glass. The movement of the curtain 201 is well known to those skilled in the art and will not be described in detail here.

[0087] Reference Figure 2 and Figure 7 , the frame 3 includes a first mounting seat 301 extending along the first direction X. The reel assembly 5 extends along the first direction X and is disposed in the first mounting seat 301 .

[0088] like Figure 8 As shown, a support plate 31 is provided at the first end of the first mounting seat 301. The support plate 31 extends upward along the vertical direction Z. A receiving port 311 corresponding to the first mounting seat 301 is configured on the support plate 31. Figure 9 As shown, a mounting plate 32 extending in the vertical direction Z is provided at the second end of the first mounting seat 301. A receiving groove 321 corresponding to the first mounting seat 301 is configured on the mounting plate 32. For example, a circular flange 322 is provided on the side of the mounting plate 32 facing the support plate 31, and the flange 322 defines the receiving groove 321. In other embodiments, the receiving groove 321 can also be configured as a depression on the mounting plate 32.

[0089] The active end 501 of the reel assembly 5 is rotatably held in the receiving opening 311 (eg Figure 5 As shown), the driven end 502 of the reel assembly 5 is rotatably accommodated in the accommodating groove 321 (as shown Figure 18 As shown in the figure, the reel assembly 5 is thus rotatably mounted on the first mounting seat 301 (or frame 3). In one embodiment, the receiving opening 311 is arc-shaped; the driving end 501 has a circular cross-section that matches the receiving opening 311; the receiving slot 321 is circular, and the driven end 502 has a circular cross-section that matches the receiving slot 321. Thus, the reel assembly 5 can rotate within the first mounting seat 301.

[0090] The support plate 31 supports the reel assembly 5 along the second direction Y. When the first pull cord 204a applies a pulling force along the second direction Y to the active end 501 of the reel assembly 5, the support plate 31 absorbs a portion of the pulling force, thereby reducing the pulling force on the drive assembly 4. This reduces the radial load on the drive assembly 4, thus preventing the adverse effects of a large radial load on the drive assembly 4.

[0091] In addition, the support plate 31 also supports the active end 501 of the reel assembly 5 along the vertical direction Z. This helps to make the active end 501 of the reel assembly 5, the transmission shaft 6 and the shaft hole 421 on the drive assembly 4 (such as Figure 4b (As shown) the three maintain good coaxiality to ensure good performance of the sunshade assembly 2.

[0092] Also like Figure 8 As shown, the peripheral edge 315 of the receiving opening 311 is provided with a notch 312 , which is generally upward in the vertical direction Z. Thus, the active end 501 of the reel assembly 5 can pass through the notch 312 and be installed in the receiving opening 311 , facilitating the assembly of the sunshade assembly 2 .

[0093] The size of the notch 312 is smaller than or equal to the radial dimension of the active end 501 of the reel assembly 5. This prevents the active end 501 of the reel assembly 5 from slipping out of the receiving opening 311 and damaging the sunshade assembly 2. In one embodiment, the support plate 31 has appropriate elasticity. Thus, when the reel assembly 5 is installed, the active end 501 of the reel assembly 5 expands the notch 312, allowing it to pass through the notch 312 and enter the receiving opening 311. Subsequently, the notch 312 regains its shape, retaining the active end 501 of the reel assembly 5 within the receiving opening 311.

[0094] In one embodiment, the support plate 31 can be made of a plastic material with suitable elasticity to facilitate elastic deformation of the notch 312 and help reduce the weight of the sunshade device 2. For example, the plastic material can be glass fiber reinforced polypropylene. Of course, other suitable materials can also be used to manufacture the support plate, depending on the actual situation, and will not be discussed here. Preferably, the support plate 31, mounting plate 32, and frame 3 are integrally injection molded, which simplifies the manufacture of the sunshade device 2.

[0095] Also like Figure 8 As shown, the notch 312 includes a first side 313 and a second side 314. The first side 313 is located in front of the second side 314 along the second direction Y, and the first side 313 is higher than the second side 314. When the sunshade device 2 is in use, the active end 501 of the reel assembly 5 is primarily subjected to the forward pulling force from the first pull cord 204a along the second direction Y. Therefore, the circumferential edge portion of the receiving opening 311 adjacent to the first side 313 will bear part of the pulling force and constrain the active end 501 of the reel assembly 5 along the second direction Y. The active end 501 of the reel assembly 5 is hardly subjected to backward force along the second direction Y. Therefore, as long as the height of the second side 314 can stably maintain the active end 501 of the reel assembly 5 within the receiving opening 311, the height of the second side 314 can be appropriately lowered.

[0096] In other embodiments, the heights of the first side and the second side may be substantially equal. In this case, the central angle of the notch should be less than 180 degrees (e.g., between 200 degrees and 270 degrees) so that the active end of the reel assembly is not easily dislodged from the receiving port through the notch.

[0097] Reference Figure 11 and Figure 12The reel assembly 5 comprises a first rope wheel 51, a second rope wheel 52 and a tubular reel body 53 extending along the first direction X. The curtain fabric 201 can be wound onto or released from the reel body 53. The first rope wheel 51 is fixedly installed at a first end 531 of the reel body 53 to form a driving end 501. The second rope wheel 52 is fixedly installed at a second end 532 of the reel body 53 to form a driven end 502. The first connecting section 61 of the transmission shaft 6 is connected with the first end 531 of the reel body 53 and is spaced apart from the first rope wheel 51. For example, the first connecting section 61 of the transmission shaft 6 is inserted into the inside of the first end 531 of the reel body 53, and the first rope wheel 51 is sleeved on the circumferential outer surface of the first end 531 of the reel body 53 (as shown in Figure 16 and Figure 17 According to this structure, the transmission shaft 6 directly drives the reel body 53 to rotate, and there is no connection relationship between the transmission shaft 6 and the first rope wheel 51 (in fact, the first rope wheel 51 and the second rope wheel 52 are driven to rotate by the reel body 53). Compared with the prior art technical solution in which the transmission shaft drives the rope wheel to rotate, and the rope wheel in turn drives the reel body to rotate (that is, the rope wheel plays a transmission role between the transmission shaft and the reel body), in the technical solution of the present application, the first rope wheel 51 does not play a transmission role and has less load, which helps to improve the working reliability of the sunshade curtain device 2.

[0098] In addition, the first rope wheel 51 and the second rope wheel 52 are fixedly connected together with the reel body 53. During the process of winding or releasing the curtain fabric 201 onto or from the reel body 53, the first rope wheel 51 and the second rope wheel 52 always maintain the same rotational speed as the reel body 53, so that the movement speeds of the two ends of the tensioning member 207 on the curtain fabric 201 are equal, which helps to avoid wrinkles of the curtain fabric 201.

[0099] Now the structure of the first rope wheel 51 will be described. As shown in Figure 14As shown, the first rope pulley 51 includes a first rope winding portion 511 and a first mounting portion 512. For example, the first rope winding portion 511 is generally conical and has a spiral groove. The first pull rope 204a is wound within the spiral groove and can be wound onto or released from the first rope winding portion 511. The first mounting portion 512 extends from the first rope winding portion 511 in the first direction X and away from the reel body 53. The first mounting portion 512 is annular and has a circumferentially extending mounting groove 513 formed on its circumferential surface. At least a portion of the circumferential edge 315 of the receiving opening 311 fits within the mounting groove 513. For example, if the receiving opening 311 is generally oblong, a curved portion of the circumferential edge 315 of the receiving opening 311 fits within the mounting groove 513; if the receiving opening 311 is arcuate, the entire circumferential edge 315 of the receiving opening 311 may fit within the mounting groove 513. The first rope pulley 51 is rotatable relative to the receiving opening 311. This ensures that the active end 501 of the reel assembly 5 is rotatably retained within the receiving opening 311. Furthermore, the mounting groove 513 and the support plate 31 constrain each other along the first direction X, preventing the support plate 31 from disengaging from the first rope pulley 51 along the first direction X. Furthermore, the support plate 31 is spaced apart from the first rope winding portion 511 to avoid interfering with the winding or releasing of the first pull cord 204a on the first rope winding portion 511, thereby improving the stability of the movement of the curtain fabric 201.

[0100] In one embodiment, a lubricant may be applied between the circumferential edge 315 of the receiving port 311 and the mounting groove 513 to reduce the friction between the circumferential edge 315 of the receiving port 311 and the mounting groove 513, thereby reducing the load of the drive assembly 4 and reducing or avoiding the noise generated by the friction between the receiving port 311 and the mounting groove 513.

[0101] like Figure 13 As shown, the mounting groove 513 includes two opposing side walls 514 and a bottom wall 515 connected between the two side walls 514. A protrusion 316 is provided on one side surface of the support plate 31, and the protrusion 316 contacts a corresponding side wall 514. This reduces the contact area between the side surface of the support plate 31 and the corresponding side wall 514 of the mounting groove 513, thereby helping to reduce the load on the drive assembly 4. It should be understood that protrusions can also be provided on both side surfaces of the support plate, and this will not be repeated here.

[0102] The installation of the first sheave 51 on the first end 531 of the reel body 53 is described below. Figure 15 As shown, the first rope pulley 51 is configured with a mounting sleeve 516 extending along the first direction X. For example, the mounting sleeve 516 is located inside the first rope winding portion 511. A first assembly protrusion 517 is configured on the circumferential inner surface of the mounting sleeve 516.

[0103] like Figure 12 and Figure 16 As shown, a first assembly opening 533 is configured on the circumferential side wall of the first end 531 of the reel body 53. For example, the first assembly opening 533 extends from the edge of the first end 531 of the reel body 53 along the first direction X toward the second end 532 of the reel body 53.

[0104] When installing the first rope pulley 51, align the first assembly protrusion 517 with the first assembly opening 533, and then move the first rope pulley 51 toward the reel body 53 along the first direction X until the first assembly protrusion 517 fits into the first assembly opening 533 (as shown in FIG. Figure 16 As shown in FIG. 1 , the mounting sleeve 516 is thus mounted on the first end 531 of the reel body 53, and the first rope pulley 51 is thus mounted on the first end 531 of the reel body 53. The reel body 53 drives the first rope pulley 51 to rotate via the first mounting protrusion 517. In other words, the first mounting protrusion 517 acts like a transmission key.

[0105] Also like Figure 15 As shown, the first rope pulley 51 is further configured with a plurality of pressing ribs 518 protruding from the circumferential inner surface of the mounting sleeve 516. These pressing ribs 518 extend along the first direction X. When the mounting sleeve 516 of the first rope pulley 51 is mounted on the first end 531 of the reel body 53, not only the first assembly protrusion 517 fits into the first assembly opening 533, but also these pressing ribs 518 abut against the circumferential outer surface of the first end 531 of the reel body 53 (as shown in FIG. Figure 16 As shown), the first rope pulley 51 is fixedly assembled on the reel body 53 and rotates synchronously with the reel body 53. In addition, this installation method of the first rope pulley 51 does not require additional fixing parts, which reduces the number of parts of the sunshade device 2 and reduces the cost of the sunshade device 2.

[0106] The following describes the assembly of the first connecting section 61 of the transmission shaft 6 and the reel body 53. Figure 12 、 Figure 16 and Figure 17 A second assembly opening 534 and a connection hole 535 are further configured on the circumferential side wall of the first end 531 of the reel body 53. The second assembly opening 534 extends from the edge of the first end 531 of the reel body 53 along the first direction X toward the second end 532 of the reel body 53, and the second assembly opening 534 and the first assembly opening 534 are offset from each other along the circumferential direction of the reel body 53. The connection hole 535 is away from the edge of the first end 531 of the reel body 53. In one embodiment, the connection hole 535 is further offset from the second assembly opening 534 along the circumferential direction of the reel body 53, for example, by approximately 180 degrees.

[0107] like Figure 10As shown, the first connecting section 61 of the transmission shaft 6 is configured with a second assembly protrusion 612 protruding from the circumferential surface of the first connecting section 61 and a connecting hook 611 offset from the second assembly protrusion 612. The second assembly protrusion 612 corresponds to the second assembly opening 534, and the connecting hook 611 corresponds to the connecting hole 535.

[0108] When assembling the transmission shaft 6 with the reel body 53, the second assembly protrusion 612 is aligned with the second assembly opening 534. The transmission shaft 6 is then moved into the reel body 53 along the first direction X until the second assembly protrusion 612 engages with the second assembly opening 534 and the connecting hook 611 engages with the connecting hole 535. In this way, the engagement of the connecting hook 611 with the connecting hole 535 prevents the reel body 53 and the transmission shaft 6 from disengaging in the axial direction of the reel body 53. The transmission shaft 6 drives the reel body 53 to rotate via the second assembly protrusion 612. In other words, the second assembly protrusion 612 acts like a transmission key.

[0109] Furthermore, when assembling the sunshade device 2, the transmission shaft 6 is first assembled with the reel body 53. Then, the second connecting section 62 of the transmission shaft 6 is connected to the drive assembly 4. During this process, the engagement of the connecting hook 611 with the connecting hole 535 prevents the transmission shaft 6 from being separated from the reel body 53.

[0110] Also like Figure 10 As shown, two slits 613 extending along the first direction X are constructed on the first connecting section 61 of the transmission shaft 6. The two slits 613 are spaced apart along the circumference of the first connecting section 61, and the connecting hook 611 is located between the two slits 613, which makes the connecting hook 611 have appropriate elasticity. When the transmission shaft 6 is inserted into the reel body 53, the connecting hook 611 is squeezed by the reel body 53 and elastically deformed. When the connecting hook 611 reaches the connecting hole 535, the shape of the connecting hook 611 automatically recovers and fits into the connecting hole 535. When the first connecting section 61 of the transmission shaft 6 is installed in place in the reel body 53, the shape of the connecting hook 611 automatically recovers and makes a clicking sound. The operator can use this sound to determine whether the transmission shaft 6 and the reel body 53 are assembled in place.

[0111] Also like Figure 10 As shown, a plurality of abutment protrusions 614 are provided on the circumferential outer surface of the first connecting section 61 of the transmission shaft 6. After the first connecting section 61 of the transmission shaft 6 is inserted into the reel body 53, these abutment protrusions 614 abut against the inner surface of the reel body 53 (as shown in FIG. Figure 17 As shown). In this way, the transmission shaft 6 and the reel body 53 will not or almost will not move relative to each other in the radial direction, thereby avoiding abnormal noise when the sunshade device 2 is in use.

[0112] In one embodiment, Figure 10As shown, with the insertion direction C of the first connecting section 61 of the transmission shaft 6 into the reel body 53 as a reference, the front surface of each abutting protrusion 614 is configured as a guiding slope, and the front surface of the connecting hook 611 is also configured with a similar guiding slope. When the first connecting section 61 of the transmission shaft 6 is inserted into the reel body 53, these guiding slopes help reduce the movement resistance of the transmission shaft 6, thereby further facilitating the assembly of the transmission shaft 6 and the reel body 53.

[0113] The structure of the second rope pulley 52 is similar to that of the first rope pulley 51. Only the main differences between the two are described below. Figure 11 and Figure 18 The second rope sheave 52 includes a second rope winding portion 521 and a second mounting portion 522. The second mounting portion 522 extends from the second rope winding portion 521 in the first direction X and away from the reel body 53. The second pull rope 204b is adapted to be wound onto or released from the second rope sheave 52. It should be noted that the second mounting portion 522 does not have a mounting groove structure like that on the first rope sheave. In other embodiments, the second rope sheave can be identical to the first rope sheave, but without the mounting groove on the second rope sheave.

[0114] The second mounting portion 522 is rotatably received in the receiving groove 321 on the mounting plate 32. The connection method between the second rope pulley 52 and the second end 532 of the reel body 53 is substantially the same as that of the first rope pulley 51, and will not be repeated here.

[0115] In one embodiment, a suitable gap exists between the second mounting portion 522 of the second pulley 52 and the mounting plate 32 along the first direction X. Thus, when assembling the sunshade device 2, the position of the reel assembly 5 relative to the frame 3 (or the first mounting base 301) can be adjusted along the first direction X as needed to center the curtain fabric 201 between the two guide rails 202. Furthermore, this gap can also absorb the cumulative tolerances of the various components of the reel assembly 5 along the first direction X, further facilitating assembly of the reel assembly 5.

[0116] The drive assembly 4 is described below. Figure 4a and Figure 4b As shown, the driving assembly 4 includes a motor 41 and a transmission member 42. The transmission member 42 is configured with an axial hole 421 along the first direction X. Such a driving assembly 4 is well known to those skilled in the art and will not be described in detail here.

[0117] Also like Figure 7 As shown, the frame 3 further includes a second mounting seat 302. The second mounting seat 302 extends along the first direction X and is arranged side by side with the first mounting seat 301 along the second direction Y. For example, the second mounting seat 302 and the guide rail 202 are respectively located on both sides of the first mounting seat 301 along the second direction Y. Figure 4a and Figure 4bThe motor 41 is disposed within the second mounting seat 302 along a first direction X (e.g., the motor's output shaft (not shown) is substantially parallel to the first direction X). The transmission member 42 extends from the second mounting seat 302 to the first mounting seat 301 along a second direction Y. The shaft hole 421 of the transmission member 42 is aligned with the receiving opening 311 of the support plate 31 and the reel assembly 5. This allows the first connecting section 61 of the transmission shaft 6 to be connected to the reel assembly 5 (or the reel body 53), and the second connecting section 62 of the transmission shaft 6 is inserted into the shaft hole 421. When the sunshade device 2 is in use, the motor 41 rotates and drives the transmission shaft 6 to rotate via the transmission member 42. The transmission shaft 6 then drives the reel assembly 5 to rotate.

[0118] Also refer to Figure 4b and Figure 5 , a first mounting hole 303 is provided on the frame 3 along the first direction X. For example, mounting posts 304 extending along the vertical direction Z are provided on both sides of the second mounting base 302 along the second direction Y. Each mounting post 304 is provided with a first mounting hole 303. Two second mounting holes 422 are provided on the drive assembly 4 (e.g., the transmission member 42) along the first direction X. The two second mounting holes 422 correspond to the two first mounting holes 303, respectively.

[0119] When assembling the sunshade device 2, the drive assembly 4 is set on the frame 3 along the first direction X. For example, the motor 41 is inserted into the second mounting seat 302 along the first direction X, and the two second mounting holes 422 are aligned with the two first mounting holes 303 respectively. Then, fasteners 305 (such as bolts) are set in the aligned second mounting holes 422 and the first mounting holes 303 along the first direction X to fasten the drive assembly 4 to the frame 3 along the first direction X. According to the solution of the present application, when maintaining and / or replacing the drive assembly 4, it is only necessary to remove the fasteners 305 in the first direction X, and the drive assembly 4 can be pulled out from the frame 3 along the first direction X without removing the roof panel 12 and / or the sunroof glass 13. Similarly, the drive assembly 4 can also be inserted into the frame 3 along the first direction X, and the fasteners 305 can be installed along the first direction X, which also does not require removing the roof panel 12 and / or the sunroof glass 13. In the prior art, fasteners and drive assemblies are typically arranged vertically, which requires disassembly of the roof panel and / or sunroof glass when maintaining and / or replacing the drive assembly. Compared to the prior art, the present invention simplifies maintenance and / or replacement of the drive assembly.

[0120] In addition, in the process of installing the drive assembly 4, first, the shaft hole 421 on the transmission member 42 is aligned with the second connecting section 62 of the transmission shaft 6. Then, the drive assembly 4 is moved in the first direction X so that the second connecting section 62 of the transmission shaft 6 is inserted into the shaft hole 421 and the motor 41 is entered into the second mounting seat 302. Finally, the fastener 305 is arranged in the first direction X to fix the drive assembly 4 on the frame 3 in the first direction X. During the installation process, the drive assembly 4 is not subjected to the force in the vertical direction Z, so the drive assembly 4 will not be displaced in the vertical direction Z. In this way, after the installation of the drive assembly 4 is completed, the shaft hole 421 on the transmission member 42 is well coaxial with the transmission shaft 6 and well matched together, which helps to improve the performance of the sunshade curtain assembly 2.

[0121] In addition, according to the technical solution of the present application, in the design of the sunshade curtain device, by appropriately adjusting the position of the first mounting hole and / or the second mounting hole in the vertical direction, the drive assembly can be adjusted by rotating around the transmission shaft as the center, so that the sunshade curtain device can be adapted to the narrow installation space (for example, the space between the roof panel and the sunroof glass), which simplifies the design process of the sunshade curtain device.

[0122] Further referring to Figure 10 and Figure 19 , the shaft hole 421 is a polygonal hole, and the circumferential surface of the second connecting section 62 of the transmission shaft 6 is configured to match the shape of the shaft hole 421 (for example, generally prismatic). In this way, when the shaft hole 421 is sleeved on the second connecting section 62 of the transmission shaft 6, the axis of the transmission shaft 6 can be automatically aligned with the center of the shaft hole 421 and the transmission shaft 6 and the shaft hole 421 can be ensured to have good coaxiality. In addition, the cooperation of the shaft hole 421 and the second connecting section 62 of the transmission shaft 6 in this shape also ensures that the shaft hole 421 and the transmission shaft 6 always rotate synchronously, avoiding the motor 41 idling, which further improves the performance of the sunshade curtain assembly 2.

[0123] In one embodiment, the second connecting section 62 of the transmission shaft 6 is configured to gradually reduce in cross-sectional size in the direction away from the first connecting section 61. The shape of the shaft hole 421 matches the shape of the second connecting section 62 of the transmission shaft 6. For example, the second connecting section 62 of the transmission shaft 6 is generally prism-shaped; correspondingly, the shaft hole 421 is generally a prism-shaped hole. When the drive assembly 4 is installed on the frame 3, the further the drive assembly 4 moves in the direction from the second connecting section 62 to the first connecting section 61, the tighter the shaft hole 421 is sleeved on the second connecting section 62 of the transmission shaft 6, thereby realizing the fixed connection of the transmission member 42 and the transmission shaft 6. It should be understood that, as described above, after the drive assembly 4 is installed in place on the frame 3, the fastener 305 is used to fix the drive assembly 4 on the frame 3 to avoid the transmission member 42 and the transmission shaft 6 from being loose.

[0124] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
