Description

Technical Field

[0001] This application relates to the field of vehicle sunroofs, specifically to a sunshade device, a sunroof device, and a vehicle. Background Technology

[0002] With the diversification of vehicle appearance, many vehicles are equipped with sunroofs to enhance their aesthetics and functionality. Typically, sunshades are installed to block the sunroof.

[0003] However, sunshades require a corresponding support structure to keep them stable during movement. This support structure occupies a lot of space, thus encroaching on the interior space of the vehicle. Summary of the Invention

[0004] In a first aspect, this application provides a sunshade device, the sunshade device comprising:

[0005] A curtain assembly, wherein a first side of the curtain assembly is a light-blocking side and a second side of the curtain assembly is a light-transmitting side; or, the first side is a light-transmitting side and the second side is a light-blocking side.

[0006] A slide rail assembly has an annular track, along which a curtain assembly can reciprocate. The annular track includes a top side and a bottom side. When the curtain assembly moves to the bottom side of the annular track, a first side of the curtain assembly faces the top side of the annular track, and a second side faces away from the top side of the annular track. When the curtain assembly moves to the top side of the annular track, a first side of the curtain assembly faces the bottom side of the annular track, and a second side faces away from the bottom side of the annular track.

[0007] The curtain assembly includes an annular transmission component and a curtain. The curtain is connected to the annular transmission component, and the annular transmission component drives the curtain to move back and forth in the annular track of the slide rail assembly.

[0008] The slide rail assembly includes a slide rail and a rotating shaft. The slide rail has a first sliding groove and a second sliding groove arranged opposite to each other. The annular transmission member is embedded in the first sliding groove and the second sliding groove. The rotating shaft has an annular groove. One end of the annular transmission member is sleeved in the annular groove. The rotating shaft drives the annular transmission member to make annular motion in the first sliding groove, the second sliding groove and the annular groove.

[0009] The sunshade device further includes a fixing block, one end of which is connected to the slide rail and the other end of which is connected to the rotating shaft. The fixing block assembles the slide rail and the rotating shaft into one unit.

[0010] The sunshade device further includes a support member. The curtain has a first end and a second end that are disposed opposite each other in the extension direction of the slide rail. The support member is disposed at the first end of the curtain and is used to support the curtain. The support member can move from the first end to the second end through the slide rail.

[0011] The slide rail has a third sliding groove, which is disposed between the first sliding groove and the second sliding groove. The support member moves back and forth within the third sliding groove in the direction from the first end toward the second end.

[0012] The rotating shaft includes a first rotating shaft and a second rotating shaft, with the first rotating shaft and the second rotating shaft arranged opposite to each other.

[0013] The sunshade device further includes a motor, which is connected to the first rotating shaft and / or the second rotating shaft. The motor drives the first rotating shaft and / or the second rotating shaft to rotate, so that the first rotating shaft and / or the second rotating shaft drives the annular transmission component to perform annular motion.

[0014] The motor has a first mating part, and the rotating shaft has a second mating part, with the first mating part and the second mating part being rotatably connected.

[0015] In existing technologies, the curtain fabric is typically wound around a rotating shaft, and the thickness of the wound fabric occupies space perpendicular to the direction of the curtain fabric after winding. Therefore, this application utilizes the rotating shaft to rotate the annular transmission member, allowing the curtain fabric to move back and forth between the first and second sides along the annular track, thus reducing the space occupied by the rotating shaft in the direction perpendicular to the curtain fabric. Consequently, the sunshade device provided by this application occupies less space, increasing the interior space of the vehicle.

[0016] Secondly, this application provides a sunroof device, the sunroof device comprising:

[0017] Glass components; and

[0018] As described in the first aspect, the sunshade device is fixedly connected to the glass assembly.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0040] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0041] In this document, references to "embodiment" or "implementation" mean that a particular feature, structure, or characteristic described in connection with an embodiment or implementation may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0042] To better understand the technical solution of this application, the first direction mentioned herein refers to the X direction, the second direction refers to the Y direction, and the third direction refers to the Z direction.

[0043] This application provides a sunshade device 100, please refer to... Figures 1 to 3bThe sunshade device 100 includes a curtain assembly 10, wherein a first side 15a of the curtain assembly 10 is a light-blocking side and a second side 15b of the curtain assembly 10 is a light-transmitting side; or, the first side 15a is a light-transmitting side and the second side 15b is a light-blocking side; and a slide rail assembly 20, wherein the slide rail assembly 20 has an annular track 21, and the curtain assembly 10 is capable of reciprocating along the annular track 21. The annular track 21 includes a top side 21a and a bottom side 21b. When the curtain assembly 10... When the curtain assembly 10 moves to the bottom side 21b of the annular track 21, the first side 15a of the curtain assembly 10 is opposite to the top side 21a of the annular track 21, and the second side 15b is opposite to the top side 21a of the annular track 21; when the curtain assembly 10 moves to the top side 21a of the annular track 21, the first side 15a of the curtain assembly 10 is opposite to the bottom side 21b of the annular track 21, and the second side 15b is opposite to the bottom side 21b of the annular track 21.

[0044] Specifically, the annular track 21 is formed by fixing the slide rail 210 to the fixing block 40. The annular track 21 also includes a pair of connecting sides 21c connecting the top side 21a and the bottom side 21b. The curtain assembly slides from the bottom side 21b to the top side 21a through one of the connecting sides 21c, or the curtain assembly slides from the top side 21a to the bottom side 21b through one of the connecting sides 21c. The first side 15a and the second side 15b of the curtain assembly 10 are arranged opposite each other in a third direction. The curtain assembly 10 has a first state and a second state. The first state is a light-blocking state. At this time, the first side 15a of the curtain assembly 10 is opposite to the top side 21a of the annular track 21, and the second side 15b is opposite to the top side 21a of the annular track 21. The second state is a light-transmitting state. In this state, the first side 15a of the curtain assembly 10 is opposite to the bottom side 21b of the annular track 21, and the second side 15b is opposite to the bottom side 21b of the annular track 21. The curtain assembly 10 can be switched between the first state and the second state by the slide rail assembly 20.

[0045] In related technologies, existing sunshade devices 100 generally use a roller mechanism for storage. However, the roller diameter of the sunshade device 100 is φ20mm, and the diameter of the curtain 12 after rolling up is about φ48mm. The roller is fixed to the glass assembly 200 or the vehicle frame. Since the gap between the sunshade assembly and the vehicle body must be greater than 8mm when the curtain is rolled up, the largest third-party space occupied by the existing electric sunshade assembly is at the roller fixing point, and the space occupied by the existing sunshade assembly cannot be reduced.

[0046] Based on this, in this application, the first side 15a of the sunshade device 100 is set as the light-blocking side, and the second side 15b is set as the light-transmitting side. Then, the curtain assembly 10 is switched between the first state and the second state by the slide rail assembly 20, realizing the characteristics of light blocking and light transmission. In other embodiments, the sunshade device 100 may also set the first side 15a as the light-transmitting side and the second side 15b as the light-blocking side. For specific settings, please refer to the above description, which will not be repeated here. In this application, the rotation of the rotating shaft drives the rotation of the annular transmission member, so that the curtain can switch back and forth between the first side and the second side along the annular transmission member in the annular track. This reduces the space occupied by the rotating shaft in the direction perpendicular to the curtain, that is, reduces the distance between the sunshade device 100 and the glass assembly 200, thereby making the space occupied by the sunshade device 100 small, and thus increasing the interior space of the vehicle 500.

[0047] For further information, please refer to [link / reference]. Figure 1 and Figure 3b The curtain assembly 10 includes an annular transmission member 11 and a curtain 12. The curtain 12 is connected to the annular transmission member 11, and the annular transmission member 11 drives the curtain 12 to move back and forth in the annular track 21 of the slide rail assembly 20.

[0048] In this embodiment, the curtain 12 has a light-transmitting surface and a light-blocking surface. The side of the curtain 12 facing away from the light-blocking side is the light-transmitting surface, and the side facing away from the light-transmitting side is the light-blocking surface. The light-transmitting surface and the light-blocking surface are arranged opposite each other in a third direction. The curtain 12 is made of materials such as polyester fiber or PVDF film. The light transmittance of the light-blocking surface of the curtain 12 is 3%-15%, and the light transmittance of the light-transmitting surface of the curtain 12 is 30%-60%. The curtain assembly 10 includes two annular transmission members 11 arranged opposite each other in the first direction X. The annular transmission members 11 are flexible structures and are composed of materials including but not limited to silicone, polyurethane, and rubber. The annular transmission members 11 move in a ring along the second direction. The side of the curtain 12 is connected to half of the annular transmission member 11, and the side of the curtain 12 and the annular transmission member 11 can be fixedly connected by sewing, bonding, or other methods. By connecting the curtain 12 to the annular transmission member 11 in a half-circle manner, the area of ​​the annular transmission member 11 that is not connected to the curtain 12 is exposed, thus avoiding obstruction or interference with the area where the curtain 12 is connected to the annular transmission member 11. It can be understood that the curtain 12 only needs to rotate half a circle via the annular transmission member to switch from the first state to the second state.

[0049] Furthermore, please refer to the following: Figure 1 , Figure 2 and Figure 4 The slide rail assembly 20 includes a slide rail 210 and a rotating shaft 22. The slide rail 210 has a first sliding groove 31 and a second sliding groove 32 that are disposed opposite to each other. The annular transmission member 11 is embedded in the first sliding groove 31 and the second sliding groove 32. The rotating shaft 22 has an annular groove 221a. One end of the annular transmission member 11 is sleeved in the annular groove 221a. The rotating member drives the annular transmission member 11 to make annular motion in the first sliding groove 31, the second sliding groove 32 and the annular groove 221a.

[0050] In this embodiment, the slide rail 210 can be made of a metal material with high hardness, such as aluminum alloy, iron, or silver. The slide rail 210 consists of a set of opposing first slide rails 211 and second slide rails 212, which have identical structures. The first slide rail 211 has a first sliding groove 31 and a second sliding groove 32 disposed opposite each other in the third direction, extending along the second direction. The first sliding groove 31 is located on the side of the slide rail 210 away from the glass assembly 200, and the second sliding groove 32 is located on the side of the slide rail 210 closer to the glass assembly 200. The rotating shaft 22 includes a first rotating shaft 221 and a second rotating shaft 222 arranged opposite to each other in the second direction. Both the first rotating shaft 221 and the second rotating shaft 222 are provided with annular grooves 221a that cooperate with the annular transmission member 11 at both ends in the first direction. The annular transmission member 11 is respectively sleeved in the annular grooves 221a of the first rotating shaft 221 and the annular grooves 221a of the second rotating shaft 222. The annular track 21 is formed by the first sliding groove 31, the annular grooves 221a of the first rotating shaft 221, the second sliding groove 32, and the annular grooves 221a of the second rotating shaft 222 in sequence. The first rotating shaft 221 and the second rotating shaft 222 rotate simultaneously, thereby driving the annular transmission member 11 to perform annular motion in the annular track 21, so that the curtain 12 can move back and forth between the top side 21a and the bottom side 21b of the annular track 21. That is, the curtain assembly 10 can switch back and forth between the first state and the second state to satisfy the function of the sunshade device 100 in blocking light and transmitting light. The structure of the second slide rail 212 is the same as above, and will not be described again here.

[0051] Further, please refer to Figure 1 and Figure 5The sunshade device 100 also includes a fixing block 40, one end of which is connected to the slide rail 210 and the other end of which is connected to the rotating shaft 22. The fixing block 40 assembles the slide rail 210 and the rotating shaft 22 into one unit.

[0052] In this embodiment, the sunshade device 100 includes a plurality of fixing blocks 40, which are respectively disposed between the first rotating shaft 221 and the first slide rail 211, between the second rotating shaft 222 and the first slide rail 211, between the first rotating shaft 221 and the second slide rail 212, and between the second rotating shaft 222 and the second slide rail 212. This embodiment provides four fixing blocks 40 that sequentially connect and enclose the first rotating shaft 221, the first slide rail 211, the second rotating shaft 222, and the second slide rail 212 to form a shape.

[0053] The fixing block 40 has a body portion 41, which is provided with a slot 41a. The slot 41a is U-shaped and also has insertion holes 41b in the first direction. The concentricity of a pair of insertion holes 41b connected to the first rotating shaft 221 is 1.0 mm, and the concentricity of a pair of insertion holes 41b connected to the second rotating shaft 222 is 1.0 mm, to ensure that the parallelism of the first rotating shaft 221 and the second rotating shaft 222 is 2.0 mm, thus preventing wrinkles in the curtain 12 and affecting its appearance. The rotating shaft 22 has insertion portions 221b at both ends in the first direction that cooperate with the slot 41a. The insertion portions 221b are spaced apart from the annular groove 221a, and the insertion portions 221b are interference-fitted with the insertion holes 41b, so that the first rotating shaft 221 and the second rotating shaft 222 can be stably connected to the fixing block 40. The fixing block 40 houses the annular groove 221a and the annular transmission belt within the slot 41a, ensuring that during the re-movement of the curtain assembly 10, the annular transmission member 11 is always in contact with and rotatably connected to the annular groove 221a.

[0054] Please see Figure 1 , Figure 2 , Figure 5 and Figure 6The fixing block 40 is further provided with a first extension 42 and a second extension 43. The first extension 42 and the second extension 43 extend along a second direction on both sides of the main body 41, and the first extension 42 and the second extension 43 are arranged opposite to each other in the third direction. The first extension 42 is used to abut against the top side 21a of the first slide rail 211 and the top side 21a of the second slide rail 212, and the second extension 43 is used to abut against the bottom side 21b of the first slide rail 211 and the bottom side 21b of the second slide rail 212, so as to improve the connection stability between the fixing block 40 and the first slide rail 211 and the second slide rail 212.

[0055] The fixing block 40 is further provided with a connecting portion 44, which extends in the first direction away from the second extension portion 43. The connecting portion 44 has a plurality of first positioning holes 44a. The first slide rail 211 is further provided with a connecting plate 25, which extends in the first direction toward the side opposite to the curtain 12. The connecting plate 25 has a second positioning hole 25a. The first positioning hole 44a and the second positioning hole 25a are coaxially arranged. The sunshade device 100 is further provided with a plurality of fasteners (not shown), which pass through the first positioning holes 44a and the second positioning holes 25a to lock the connecting plate 25 of the first slide rail 211 to the connecting portion 44 of the fixing block 40, thereby improving the connection stability between the fixing block 40 and the first slide rail 211. The structure of the second slide rail 212 is the same as that of the first slide rail 211, and will not be described in detail here.

[0056] This embodiment provides fixing blocks 40 between the first rotating shaft 221 and the first slide rail 211, between the second rotating shaft 222 and the first slide rail 211, between the first rotating shaft 221 and the second slide rail 212, and between the second rotating shaft 222 and the second slide rail 212. This securely connects the first rotating shaft 221 and the second rotating shaft 222, as well as the first slide rail 211 and the second slide rail 212, and prevents the curtain 12 from wrinkling during rotation, thereby improving the structural stability of the sunshade device 100.

[0057] Further, please refer to Figure 1 , Figure 7 and Figure 8The sunshade device 100 further includes a support member 50. The curtain 12 has a first end 121 and a second end 122 disposed opposite to each other in the extension direction of the slide rail 210. The support member 50 is disposed at the first end 121 of the curtain 12. The support member 50 is used to support the curtain 12 and can move from the first end 121 to the second end 122 through the slide rail 210.

[0058] In this embodiment, the first end 121 and the second end 122 are arranged opposite to each other in the second direction. The support member 50 extends along the first direction. The first end 121 is located on the bottom side 21b of the annular track 21, and the second end 122 is located on the top side 21a of the annular track 21. The support member 50 is made of metal or plastic. The support member 50 and the first end 121 of the curtain 12 can be fixedly connected by adhesive, screwing, or other methods. The support member 50 can support the curtain 12 to prevent it from sagging and wrinkling, thereby affecting the light transmittance and light blocking properties of the curtain 12. The support member 50 has locking portions 51 at both ends in the first direction. The locking portions 51 are inserted into the first slide rail 211 and the second slide rail 212. The support member 50 can move back and forth between the first slide rail 211 and the second slide rail 212 along the second direction. The support member 50 drives the curtain 12 to move in a ring within the first sliding groove 31 and the second sliding groove 32.

[0059] In one implementation method, please refer to the following: Figure 7 and Figure 9 The sunshade device 100 also includes a handle portion 60. The side of the handle portion 60 facing the support member 50 protrudes to form a boss, which passes sequentially through the curtain 12 and the support member 50. The handle portion 60 is locked to the support member 50. The side of the handle portion 60 facing away from the support member 50 forms a handle groove, which allows the user to move the support member 50. The handle portion 60 is located at the first end 121 of the curtain 12, and the boss is positioned in the third direction facing the glass assembly 200. The handle portion 60 has multiple third positioning holes 60a, and the support member 50 has multiple fourth positioning holes 50a. Each third positioning hole 60a and each fourth positioning hole 50a is aligned one-to-one. Fasteners pass through the third positioning holes 60a and fourth positioning holes 50a to fix the handle portion 60 to the support member 50. The user can pull the curtain assembly 10 in the slide rail assembly 20 in the second direction using the handle portion 60. This allows users to manually switch the curtain assembly 10 between the first and second states, improving the mobility of the sunshade device 100.

[0060] Further, please refer to Figure 2 , Figure 8 and Figure 10 The slide rail 210 has a third sliding groove 33, which is disposed between the first sliding groove 31 and the second sliding groove 32. The support member 50 moves back and forth within the third sliding groove 33 along the direction from the first end 121 toward the second end 122.

[0061] In this embodiment, the sunshade device 100 further includes a slider 70, which has a limiting groove 70a. The engaging part 51 is inserted into the limiting groove 70a, and the slider 70 drives the engaging part 51 to move back and forth within the third sliding groove 33 along the direction from the first end 121 toward the second end 122. The slider 70 is disposed within the third sliding groove 33 of the first slide rail 211, and the slider 70 is slidably connected to the third sliding groove 33. The limiting groove 70a is formed on the side of the slider 70 facing the support member 50, and the engaging part 51 of the support member 50 is clearance-fitted with the limiting groove 70a of the slider 70, so that the support member 50 can be fixed on the slider 70 and move synchronously with the slider 70. The side of the slider 70 facing the first sliding groove 31 is provided with a plurality of protrusions 71, which are elastic structures, including but not limited to cylindrical, frustum-shaped, and other structures. The protrusion 71 reduces the contact area between the slider 70 and the third sliding groove 33, thereby reducing the friction between the slider 70 and the third sliding groove 33, so that the support member 50 can move the curtain 12 more smoothly in the third sliding groove 33. Similarly, the slider 70 is also disposed in the third sliding groove 33 of the second slide rail 212, and the specific arrangement is as described above, which will not be repeated here.

[0062] Specifically, when the curtain assembly 10 is in the first state, the first end 121 of the curtain 12 is located on the bottom side 21b of the annular track 21 and close to the first rotating shaft 221, the second end 122 of the curtain 12 is located on the top side 21a of the annular track 21 and close to the second rotating shaft 222, the light-blocking surface of the curtain 12 faces the glass assembly 200, the light-transmitting surface of the curtain 12 faces away from the glass assembly 200, and the slider 70 is located on the side of the third sliding groove 33 close to the first rotating shaft 221.

[0063] Please see Figure 2 , Figure 3a and Figure 3bWhen a user needs to switch the curtain 12 from the first state to the second state, the user can pull the handle 60 from the second direction from the side near the first rotating shaft 221 to the side near the second rotating shaft 222. The support member 50 slides from the end near the first rotating shaft 221 to the end near the second rotating shaft 222 via the slider 70. At this time, the first end 121 of the curtain 12 rotates in a circle from the end near the first rotating shaft 221 to the end near the second rotating shaft 222, and the second end 122 of the curtain 12 rotates in a circle from the end near the second rotating shaft 222 to the end near the first rotating shaft 221, thus realizing the switch of the curtain 12 from the light-blocking state to the light-transmitting state.

[0064] When a user needs to switch the curtain 12 from the second state to the first state, the user can pull the handle 60 from the second direction from the side near the second rotating shaft 222 to the side near the first rotating shaft 221. The support member 50 slides from the end near the second rotating shaft 222 to the end near the first rotating shaft 221 via the slider 70. At this time, the first end 121 of the curtain 12 rotates in a circle from the end near the second rotating shaft 222 to the end near the first rotating shaft 221, and the second end 122 of the curtain 12 rotates in a circle from the end near the first rotating shaft 221 to the end near the second rotating shaft 222, thus realizing the switch of the curtain 12 from the light-transmitting state to the light-blocking state.

[0065] Understandably, when the handle 60 is not moved by external force, the annular transmission member 11 will stop rotating in annular motion. The curtain 12 can stop at any position between the first rotating shaft 221 and the second rotating shaft 222 during sliding. At this time, the curtain 12 is in a semi-transparent and semi-blocked state, and the user can switch between these states according to actual needs.

[0066] In this embodiment, the distance between the surface of the slide rail assembly 20 facing away from the glass assembly 200 and the surface of the glass assembly 200 facing the slide rail assembly 20 is d1, and d1 satisfies: 18mm≤d1≤21.5mm, so that the sunroof device 300 occupies less interior space, thereby increasing the interior space of the vehicle 500.

[0067] Further, please refer to Figure 11 and Figure 12The sunshade device 100 further includes a motor 80, which is electrically connected to the rotating shaft 22. The motor 80 drives the rotating shaft 22 to rotate, causing the rotating shaft 22 to drive the annular transmission member 11 to perform annular motion. The motor 80 has a first mating part, and the rotating shaft 22 has a second mating part, with the first mating part and the second mating part being rotatably connected.

[0068] In this embodiment, the motor 80 is disposed at one end of the first rotating shaft 221. The first rotating shaft 221 is provided with a second mating part that cooperates with the motor 80. The first mating part extends toward the first direction. The first mating part is inserted into the second mating part so that the motor 80 is fixedly connected to the first rotating shaft 221. The motor 80 controls the rotation of the first rotating shaft 221. The rotation of the first rotating shaft 221 drives the annular transmission member 11 to rotate in the annular track 21. The rotation of the annular transmission member 11 drives the curtain 12 to rotate, thereby realizing the switching of the curtain 12 between the first state and the second state. The motor 80 includes a motor body and a fixing bracket 83. The fixing bracket 83 is screwed onto the motor body 81. The fixing bracket 83 is a sheet metal structure and extends beyond the second direction. The fixing bracket 83 is fixedly connected to the connecting plate 25 of the first slide rail 211. The fixing bracket 83 has multiple fixing holes 83a. The fixing holes 83a and the second positioning hole 25a are coaxially arranged. The fastener passes through the fixing holes 83a, the second positioning hole 25a and the first positioning hole 44a to lock the fixing bracket 83, the connecting plate 25 and the connecting part 44 in sequence, so as to fix the motor 80 on the first rotating shaft 221. Optionally, the motor 80 can also be disposed on either end of the second rotating shaft 222. The rotation of the motor 80 can drive the second rotating shaft 222 to rotate, which can also realize the annular transmission component 11 rotating in annular shape on the annular track 21. The motor 80 can also be disposed at one end of both the first rotating shaft 221 and the second rotating shaft 222. This embodiment does not make specific limitations.

[0069] In this embodiment, by setting the motor 80 at one end of the rotating shaft 22, the rotation function of the first rotating shaft 221 and the second rotating shaft 222 is realized, thereby enabling the curtain 12 to switch back and forth between the first state and the second state.

[0070] In one implementation method, please refer to Figure 13The annular rotating component is meshed with the rotating shaft 22. The annular transmission component 11 has a rack and pinion structure 92. Both the first rotating shaft 221 and the second rotating shaft 222 are equipped with gears 91 that are adapted to the annular transmission component 11. The motor 80 drives the first rotating shaft 221 to rotate, and the first rotating shaft 221 drives the rack and pinion 92 to rotate through the gears 91, thereby driving the curtain 12 to move in a ring in the annular track 21. Similarly, the motor 80 can be installed on the first rotating shaft 221 and / or the second rotating shaft 222.

[0071] In one embodiment, the motor is connected to the first rotating shaft 221, and the second rotating shaft 222 includes a coil spring (not shown), which gives the second rotating shaft 222 a winding force. Since the first rotating shaft 221 has no winding force, the motor 80 drives the first rotating shaft 221 to rotate. The rotation of the first rotating shaft 221 drives the rack 92 to rotate, which in turn drives the curtain 12 to close or open. The coil spring of the second rotating shaft 222 maintains a winding force on the curtain 12, so that the curtain 12 remains taut as it rotates with the rack 92, preventing wrinkles that would affect its appearance. In other embodiments, the motor 80 may also be connected to the second rotating shaft 222, and the first rotating shaft 221 may include a coil spring, which gives the first rotating shaft 221 a winding force. Since the second rotating shaft 222 has no winding force, the motor drives the second rotating shaft 222 to rotate. The rotation of the second rotating shaft 222 drives the rack 92 to rotate, which in turn drives the curtain 12 to close or open. The coil spring of the first rotating shaft 221 always maintains a winding force on the curtain 12, so that the curtain 12 always remains taut as the rack 92 rotates, and no wrinkles appear, thus affecting its appearance.

[0072] In this embodiment, the distance between the surface of the slide rail assembly 20 away from the glass assembly 200 and the surface of the glass assembly 200 facing the slide rail assembly 20 is d2, and d2 satisfies: 29mm≤d2≤39mm, so that the sunroof device 300 occupies less interior space, thereby increasing the interior space of the vehicle 500.

[0073] Please see Figure 14 This application also provides a sunroof device 300, including a glass assembly 200 and a sunshade device 100. The sunshade device 100 can be mounted on the glass assembly 200 via a slide rail assembly 20. The slide rail assembly 20 can be fixedly connected to the glass assembly 200 by means of screwing, snap-fitting, or bonding. This embodiment is not specifically limited.

[0074] Please see Figure 15 This application also provides a vehicle 500, which includes a vehicle body 400 and a sunshade device 100, the sunshade device 100 being disposed on the top of the vehicle body 400. In this embodiment, the sunshade device 100 can be fixedly connected to the top of the vehicle body 400 via a frame (not shown). In one embodiment, the sunshade device 100 can also be fixedly connected to the glass assembly 200 first, and then the glass assembly 200 is fixedly connected to the top of the vehicle body 400. In one scenario, external light shines onto the top of the vehicle body 400, and shines into the sunshade device 100 through the glass assembly 200; the sunshade device 100 can transmit or block external light.
