[0036] The aforementioned curtain support mechanism, curtain device, and vehicle, wherein the drive mechanism drives the first support member to move along the width direction, enabling the first support member to unfold outward along the width direction. Simultaneously, the unfolding of the first support member drives the second support member to move and unfold along the width direction. Furthermore, the drive mechanism also drives the second support member to rotate, causing it to rotate outward and unfold, thereby meeting the assembly requirements of the curtain in the width direction of the vehicle body. Conversely, in the non-operating state, the drive mechanism moves in the reverse direction, causing the first support member to move towards the opposing component along the width direction, and then at least partially retract into the opposing component. The movement of the first support member also drives the second support member to move towards the opposing component. Furthermore, the drive mechanism also drives the second support member to rotate in the reverse direction, causing it to fold into the opposing component, reducing the space occupied by the curtain support mechanism inside the vehicle and meeting the compactness requirements of the interior space layout. Therefore, the curtain support mechanism can meet the unfolding width required for functions such as separation, shielding, and privacy protection, while ensuring that it does not encroach on passenger space after being retracted, thus complying with vehicle ergonomics and collision safety requirements.

Detailed Implementation
[0044] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0045] As described in the background section, the curtain support mechanism in the related art occupies a large space inside the vehicle, failing to meet the requirements for compact interior space arrangement. This is because the curtain support mechanism is typically non-foldable, resulting in a large space requirement and hindering the compact interior space arrangement. Even if the curtain device in the related art uses a rotatable and foldable curtain support mechanism to support and guide the curtain, reducing the space occupied inside the vehicle through rotation and folding, the curtain's extension range along the width of the vehicle body is limited during use, thus failing to meet the need for a large extension range.
[0046] It should be noted that the "width direction" and "opening / closing direction" in this embodiment can be referenced. Figures 1 to 5 "Width direction" as Figures 1 to 5 As shown in W, the "opening and closing direction" is as follows: Figures 1 to 5 As shown in H in the diagram.
[0047] For the reasons mentioned above, this application provides a curtain support mechanism, a curtain device, and a vehicle that can meet the technical requirements of compact interior space arrangement.
[0048] One embodiment of this application provides a means of transportation, including but not limited to any one or a combination of automobiles, ships, locomotives, buses or freight cars, which can be flexibly adjusted and configured according to actual needs.
[0049] For ease of description, this embodiment will specifically use a car as an example for detailed explanation, but it is not limited to this.
[0050] The following will combine Figures 1 to 5 A detailed description will be provided of a curtain support mechanism, curtain device, and vehicle according to an embodiment of this application.
[0051] Please see Figures 1 to 5 In one embodiment, the vehicle includes a curtain device. The installation position of the curtain device on the vehicle body can be flexibly adjusted according to actual needs. For example, for a 5-seater vehicle, the curtain device can be installed between the front and rear rows. For a 7-seater vehicle, the curtain device can be installed between the second and third rows of seats, or between the front and second rows of seats, without particular limitation.
[0052] Please see Figure 1 and Figure 3 Specifically, the curtain assembly includes a curtain support mechanism 10 and a curtain 20. For example, the curtain support mechanism 10 guides and supports the curtain 20. During the winding and unwinding of the curtain 20, the curtain support mechanism 10 guides the curtain, allowing it to smoothly complete the winding and unwinding actions. Furthermore, when the curtain 20 is unfolded and laid flat, the curtain support mechanism 10 connects to one side of the curtain 20 along its width direction W, supporting and fixing the curtain 20, ensuring it remains stable and reliable without wobbling. When the curtain 20 is wound up, the curtain support mechanism 10 folds to reduce its footprint inside the vehicle.
[0053] Please see Figure 1 or Figure 3 The curtain support mechanism 10 provided in one embodiment of this application includes a first support member 11, a second support member 12 and a drive mechanism 13.
[0054] For example, the first support member 11 is used to slidably connect to the counterpart member 30 of the vehicle body along the width direction W of the vehicle body. The counterpart member 30 includes, but is not limited to, the roof of the vehicle body, the perimeter of the vehicle body, or other sheet metal parts. Therefore, the user can design and arrange the size, orientation, and position of the counterpart member 30 according to its shape and size inside the vehicle, which helps to improve the adaptability of the counterpart member 30 inside the vehicle and optimize the space inside the vehicle.
[0055] Optionally, the first support member 11 is provided with a slider 111, and the opposing member 30 is provided with a slide rail 31 extending along the width direction W. The slider 111 is slidably disposed in the slide rail along the width direction W. Specifically, the number of slide rails 31 is not limited to one, but can be multiple, such as two, three, or other numbers. In order to simplify the structure and improve the overall stability, this embodiment takes two slide rails 31 as an example, but it is not a limitation. The two slide rails 31 are arranged parallel to each other and are located at the top and bottom of the opposing member 30, respectively. The first support member 11 has two or more sliders 111, and each slider 111 is slidably disposed in each slide rail 31. The slider 111 and the slide rail 31 cooperate with each other to play a good guiding role, so that the first support member 11 can run stably along the width direction W under the drive of the driven mechanism 13.
[0056] It is understood that the sliding member 111 may include, but is not limited to, the slider, sliding rod, sliding column, etc. on the first support member 11, as long as there is a sliding fit with the slide rail 31, and there are no restrictions here.
[0057] For example, the second support member 12 is used to connect with the curtain 20. It should be noted that the terms "connection" and "fixation" in this embodiment should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components or an interaction between two components, unless otherwise explicitly defined.
[0058] For example, the top end of the second support member 12 is rotatably connected to the first support member 11. Optionally, the top end of the second support member 12 and the first support member 11 are connected by a rotating member 14. The rotating member 14 includes, but is not limited to, a fixing pin, a connecting shaft, etc. The first support member 11 serves to support and bear the second support member 12. When the first support member 11 moves along the width direction W, it can drive the second support member 12 to move synchronously along the width direction W. Furthermore, under the drive of the drive mechanism 13, the second support member 12 can rotate relative to the first support member 11 to a preset angle position. The specific rotation angle of the second support member 12 can be flexibly adjusted and set according to actual needs, and is not particularly limited here.
[0059] For example, the drive mechanism 13 is mounted on the opponent member 30 and is connected to the first support member 11 and the second support member 12. The drive mechanism 13 drives the first support member 11 to move in the width direction W, so that the first support member 11 is at least partially retracted into the opponent member 30 or extended outward. Of course, the drive mechanism 13 is also used to drive the second support member 12 to rotate, so that the second support member 12 is at least partially retracted into the opponent member 30 or extended outward.
[0060] The aforementioned curtain support mechanism 10, curtain device, and vehicle are described above. The drive mechanism 13 drives the first support member 11 to move along the width direction W, causing it to unfold outwards along the width direction W. Simultaneously, the unfolding of the first support member 11 drives the second support member 12 to move and unfold along the width direction W. Furthermore, the drive mechanism 13 also drives the second support member 12 to rotate, causing it to rotate outwards and unfold, thus meeting the assembly requirements of the curtain 20 in the width direction W of the vehicle body. Conversely, in the non-working state, the drive mechanism 13 moves in the opposite direction, causing the first support member 11 to move towards the opposing member 30 along the width direction W, and then at least partially retract into the opposing member 30. The movement of the first support member 11 causes the second support member 12 to move towards the opposing member 30. Furthermore, the drive mechanism 13 also drives the second support member 12 to rotate in the opposite direction, causing it to fold into the opposing member 30, reducing the space occupied by the curtain support mechanism 10 inside the vehicle and meeting the compactness requirements of the vehicle's interior space layout. It can be seen that the curtain support mechanism 10 can not only meet the required unfolding width for functions such as separation, shielding and privacy protection, but also ensure that it does not encroach on the passenger space after being stored, which meets the requirements of vehicle ergonomics and collision safety.
[0061] In some embodiments, the first support member 11 may be, but is not limited to, a decorative element, such as a decorative panel. The second support member 12 may be, but is not limited to, a decorative element, such as a decorative panel. When the first support member 11 and the second support member 12 are each configured as decorative panels, after the first support member 11 and the second support member 12 are each extended outward, both the first support member 11 and the second support member 12 provide good shielding, satisfying functions such as separation, shielding, and privacy protection.
[0062] Please see Figure 1 and Figure 3 Based on the aforementioned embodiments, the drive mechanism 13 includes a drive member 131, a first moving member 132, and a first transmission member 133. The drive member 131 is used to be mounted on the opponent member 30. The drive member 131 is connected to the first moving member 132, and the drive member 131 is used to drive the first moving member 132 to move along a first direction M.
[0063] The specific structural forms of the driving component 131 are numerous, including but not limited to motor lead screw, worm gear, cylinder, hydraulic cylinder, gear rack, etc., as long as it can drive the first moving component 132 to move along the first direction M, no special restrictions are imposed here.
[0064] In some typical embodiments, the driving component 131 is a motor lead screw, that is, the driving component 131 includes a power motor 1311 and an adjusting lead screw 1312. The power motor 1311 is mounted on the opposing component 30 and is connected to the adjusting lead screw 1312. The first moving component 132 is sleeved on the adjusting lead screw 1312 and has a screw hole that matches the adjusting lead screw 1312. When the power motor 1311 drives the adjusting lead screw 1312 to rotate, the first moving component 132 cannot rotate due to the connection of the first transmission component 133, etc., and then moves along the first direction M, which is also the axial direction of the adjusting lead screw 1312. By using a motor lead screw, not only can the position of the first moving component 132 along the first direction M be adjusted, but a self-locking function can also be achieved when rotation stops, ensuring the positional stability of the first moving component 132, and thus ensuring the positional stability and reliability of the first support component 11 and the second support component 12.
[0065] One end of the first transmission member 133 is connected to the first moving member 132. Specifically, the connection between one end of the first transmission member 133 and the first moving member 132 is a movable connection, more specifically a rotatable connection. The other end of the first transmission member 133 is slidably disposed on the opponent member 30 along the second direction Z. The other end of the first transmission member 133 is also slidably disposed on the first support member 11 along the third direction P, with the second direction Z and the third direction P forming an angle.
[0066] Optionally, the first transmission component 133 may include, but is not limited to, a connecting rod, a connecting arm, etc., without any particular limitation.
[0067] Optionally, the first moving part 132 may include, but is not limited to, a moving sleeve, a moving block, etc., without any particular limitation.
[0068] In the aforementioned curtain support mechanism 10, when the driving member 131 drives the first moving member 132 to move along the first direction M, the first moving member 132 drives one end of the first transmission member 133 to move along the first direction M; the other end of the first transmission member 133 moves relative to the opponent member 30 along the second direction Z, and the other end of the first transmission member 133 also moves relative to the first support member 11 along the third direction P. Since the second direction Z and the third direction P are set at an angle, the first transmission member 133 can make the first support member 11 slide relative to the opponent member 30 along the width direction W of the vehicle body, which can realize the first support member 11 unfolding outward along the width direction W, or at least partially retracting the first support member 11 into the opponent member 30 along the width direction W.
[0069] Based on the aforementioned embodiments, the drive mechanism 13 further includes a second transmission member 134. The second transmission member 134 may include, but is not limited to, a connecting rod, a connecting arm, etc., and is not particularly limited here; it can be flexibly adjusted and set according to actual needs. One end of the second transmission member 134 is connected to the first moving member 132, and the other end of the second transmission member 134 is connected to the second support member 12. The specific connection method between one end of the second transmission member 134 and the first moving member 132 may be, for example, a movable connection or a rotating connection. The specific connection method between the other end of the second transmission member 134 and the second support member 12 may be, for example, a movable connection or a rotating connection, and is not limited here. Thus, when the drive member 131 drives the first moving member 132 to move along the first direction M, the first moving member 132 also simultaneously drives one end of the second transmission member 134 to move along the first direction M. When the second transmission member 134 moves, it correspondingly drives the second support member 12 to rotate relative to the first support member 11, thereby enabling the second support member 12 to rotate and unfold, or at least partially retract into the opponent member 30. That is, while the first support member 11 translates along the width direction W, the second support member 12 rotates synchronously relative to the first support member 11.
[0070] In some embodiments, in order to provide a sliding guide for the other end of the first transmission member 133, the hand member 30 is provided with a first guide portion 32 extending along the second direction Z, and the first support member 11 is provided with a second guide portion 112 extending along the third direction P. The first guide portion 32 and the second guide portion 112 are each, but are not limited to, guide rails, guide grooves, or slides, etc., and are not particularly limited here; they can be flexibly adjusted and set according to actual needs.
[0071] Based on the aforementioned embodiment, a second moving member 135 is provided at the other end of the first transmission member 133. The second moving member 135 includes, but is not limited to, a moving block, a moving rod, or a moving column. The second moving member 135 is slidably disposed on the first guide portion 32 along the second direction Z, and the second moving member 135 is also slidably disposed on the second guide portion 112 along the third direction P. Thus, when the driving member 131 drives the first moving member 132 to move along the first direction M, the second moving member 135 correspondingly slides relative to the first guide portion 32 along the second direction Z, and the second moving member 135 also slides relative to the second guide portion 112 along the third direction P, resulting in stable operation, thereby enabling the first support member 11 to move stably along the width direction W.
[0072] The second moving member 135 is at least partially disposed within the guide groove of the second guide portion 112, and the second moving member 135 is adapted to the guide groove. Specifically, the second moving member 135 is configured as a moving block with an outer periphery of a parallelogram, or a rectangular block, etc. The opposite sides of the second moving member 135 correspond one-to-one with the inner walls of the opposite sides of the guide groove for guidance and engagement. In this way, the second moving member 135 runs stably along the second guide portion 112, avoiding wobbling.
[0073] In some embodiments, the first guide portion 32 and the second guide portion 112 are slidably engaged with the opposite sides of the second moving member 135. That is, the second moving member 135 is located between the first guide portion 32 and the second guide portion 112, and the opposite sides of the second moving member 135 are slidably engaged with the first guide portion 32 and the second guide portion 112, respectively.
[0074] The first guide portion 32 and the second guide portion 112 are each provided with a guide groove that guides and mates with the second moving member 135. The dimensional requirements and matching principles of the guide grooves of the first guide portion 32 and the second guide portion 112 are as follows:
[0075] Please see Figure 2 The width of the guide groove is set to D1, and the width of the part of the second moving part 135 that slides with the guide groove is set to D2, where D1 > D2. Optionally, D1 - D2 = 0.1mm to 0.5mm. This ensures smooth sliding without significant gaps or wobble.
[0076] The depth of the guide groove is set to T1, and the height of the part of the second moving part 135 that slides with the guide groove is set to T2, where T1 / T2 ≥ 1 / 3. More specifically, T1 / T2 ≥ 1 / 2. Thus, the guide groove depth T1 is relatively deep, ensuring sufficient guiding length and lateral load-bearing capacity, effectively preventing the second moving part 135 from derailing, tilting, or jamming. Optionally, T1 / T2 may include, but is not limited to, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, or 1, etc., and can be flexibly adjusted and set according to actual needs, without limitation here.
[0077] The surface roughness of the guide groove is Ra, where Ra ≤ 1.6 μm. This low surface roughness effectively reduces friction, noise, and wear.
[0078] The two sides of the second moving part 135 form sliding pairs with the first guide part 32 and the second guide part 112 respectively. The mating clearance between the two sides of the second moving part 135 and the first guide part 32 and the second guide part 112 should be the same or basically consistent to avoid excessive clearance on one side causing shaking or excessive clearance causing jamming.
[0079] The width, depth, radius, and wall thickness of the guide grooves of the first guide section 32 and the second guide section 112 should match each other to ensure that the second moving part 135 always simultaneously fits the working surfaces of the first guide section 32 and the second guide section 112 throughout its entire stroke, so as not to dislodge, not to be suspended, not to interfere, and to operate stably and reliably.
[0080] The guide groove is relatively long and should cover the entire translational stroke of the first support member 11, with a safety margin of, for example, 5mm to 10mm at both ends of the stroke. This can prevent impact defects at extreme positions.
[0081] The first guide section 32 and the second guide section 112 are linear guide sections, and the straightness error of the linear guide sections is ≤0.5mm / m. This small straightness error ensures smooth movement. After assembly, the second moving part 135 can slide smoothly between the first guide section 32 and the second guide section 112 without jamming or significant swaying, without any climbing or straining.
[0082] In some embodiments, in order to provide a sliding guide for the other end of the second transmission member 134, the first support member 11 is provided with a third guide portion 113, which is an arc-shaped portion arranged around the rotation axis of the second support member 12. In this way, the third guide portion 113 can provide a sliding guide for the other end of the second transmission member 134, and the rotation between the second support member 12 and the first support member 11 is stable.
[0083] To improve the rotational stability of the second support member 12, in some embodiments, the second support member 12 is provided with a third moving member 121. The third moving member 121 is slidably disposed on the first support member 11. Thus, when the second transmission member 134 drives the second support member 12 to rotate relative to the first support member 11, the third moving member 121 slides relative to the first support member 11, thereby improving the rotational stability of the second support member 12.
[0084] Specifically, the other end of the second transmission member 134 is connected to the third moving member 121. The specific connection method between the other end of the second transmission member 134 and the third moving member 121 includes, but is not limited to, a movable connection or a hinge, and is not limited here. The other end of the second transmission member 134 acts on the third moving member 121, thereby driving the second support member 12 to rotate relative to the first support member 11.
[0085] For example, the third moving member 121 is slidably disposed on the third guide portion 113. The third guide portion 113 may include, but is not limited to, a guide rail, a guide groove, or a slide, etc., and is not particularly limited here. It can be flexibly adjusted and set according to actual needs. It can be seen that the third guide portion 113 not only plays a sliding guiding role on the other end of the second transmission member 134, but also plays a guiding role on the third moving member 121, which can improve the rotational stability of the second support member 12.
[0086] Of course, in some alternative solutions, the third moving part 121 and the third guide part 113 can be omitted, and the other end of the second transmission part 134 can also be directly slidably disposed on the first support part 11. The other end of the second transmission part 134 slides along the first support part 11 and drives the second support part 12 to move synchronously, which also enables the second support part 12 to rotate relative to the first support part 11.
[0087] For example, please refer to Figure 3 The third direction P and the width direction W satisfy the following requirement: 30° < β < 70°, where β is the angle between the third direction P and the width direction W. Specifically, β includes, but is not limited to, 32°, 35°, 38°, 45°, 50°, 55°, 60°, 65°, or 68°. Thus, the angle range of β is moderate, and the force distribution between the second moving member 135 and the second guide part 112 is more reasonable. This ensures that a sufficiently large horizontal component force drives the first support member 11 to move smoothly, while also providing a moderate normal clamping force to avoid movement jamming, abnormal noise, or vibration. Furthermore, the mechanism occupies little space, making it easy to arrange in narrow spaces.
[0088] If β≤ 30°, the slope is too gentle, the horizontal force is insufficient, the driving efficiency is low, and it is easy to experience weak movement, jamming, or even motor stall.
[0089] If β ≥ 70°, the slope will be too steep, the normal pressure will be too large, the friction loss will increase dramatically, the wear will be accelerated, the noise will be louder, and the translational stroke of the first support 11 will be difficult to guarantee.
[0090] For example, the maximum travel distance of the first support member 11 along the width direction W is S. It should be noted that the maximum travel distance is also the distance between the first support member 11 when it moves to its two extreme positions along the width direction W. S satisfies the condition: 10mm < S < 300mm. Specifically, S includes, but is not limited to, 15mm, 20mm, 30mm, 50mm, 60mm, 100mm, 120mm, 150mm, 200mm, 250mm, or 280mm. Thus, when S is within this range, it satisfies the unfolded width required for functions such as partitioning, shielding, and protecting privacy, while ensuring that it does not encroach on passenger space when folded, meeting the requirements of vehicle ergonomics and collision safety. Furthermore, the moderate travel distance results in a low motor load, smooth movement speed, and a longer mechanism lifespan.
[0091] If S≤10mm, then as S decreases, S approaches 0mm, the mechanism has no actual unfolding effect and loses its design significance.
[0092] If S≥300mm, it occupies too much lateral space inside the vehicle, which may interfere with the seats, door panels, and passenger legs; at the same time, the excessive length of the cantilever reduces rigidity and increases the risk of vibration and abnormal noise.
[0093] For example, the second direction Z and the third direction P satisfy the following condition: 10° < γ < 60°, where γ is the angle between the second direction Z and the third direction P. Specifically, γ includes, but is not limited to, 12°, 15°, 20°, 25°, 30°, 34°, 40°, 45°, 50°, 55°, or 59°, etc., and can be flexibly adjusted and set according to actual needs, without limitation here. Thus, when 10° < γ < 60°, it ensures that the second moving member 135 can be stably guided along the second direction Z, and can also effectively drive the third guide part 113 to drive the first support member 11 to translate, realizing efficient conversion of force and motion. The mechanism is more rationally stressed and less prone to defects such as lateral load imbalance, constriction, and jamming.
[0094] If γ ≤ 10°, the two guide rails are nearly parallel, the driving force is extremely weak, the motion efficiency is low, and it is easy to slip or stop moving.
[0095] If γ ≥ 60°, the included angle is too large, the lateral force of the second moving part 135 is too large, the guide rail is severely worn, the smoothness of movement is poor, and the noise and vibration are obvious.
[0096] For example, the maximum rotation angle of the second support member 12 relative to the first support member 11 is 'a'. It should be noted that the maximum rotation angle is the angle between the two extreme angle positions when the second support member 12 rotates relative to the first support member 11. 'a' satisfies: 5° ≤ a ≤ 60°. Specifically, 'a' includes, but is not limited to, 5°, 8°, 10°, 15°, 20°, 22°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, or 60°, etc., and is not limited here. It can be flexibly adjusted and set according to actual needs. Thus, on the one hand, when 'a' ≥ 5°, functions such as shielding, separation, privacy protection, and rear-seat protection can be achieved; on the other hand, when 'a' ≤ 60°, the rotation angle is gentle, the movement trajectory is controllable, without impact or jamming, and it coordinates smoothly with the translational movement of the first support member 11.
[0097] If a > 60°, the second support member 12 is prone to interference with components such as the roof, headliner, B-pillar interior trim, and seat belts. Furthermore, the increased rotational torque necessitates a corresponding increase in the length of the second transmission member 134, potentially leading to stress degradation and defects such as deformation and abnormal noise. If a < 5°, functions such as shielding, separation, privacy protection, and rear seat protection cannot be achieved.
[0098] Please see Figures 1 to 5 In another embodiment, this application also provides a curtain device, including the curtain support mechanism 10 of any of the above embodiments, and further including a curtain 20. The second support member 12 is provided with a slide rail, and the edge of the curtain 20 slides in cooperation with the slide rail to unfold or close.
[0099] The aforementioned curtain device includes a curtain support mechanism 10. The technical effect is brought about by the curtain support mechanism 10, and the beneficial effects include the beneficial effects of the curtain support mechanism 10, which will not be elaborated here.
[0100] Based on the aforementioned embodiment, two curtain support mechanisms 10 are provided, and the two curtain support mechanisms 10 are respectively located on opposite sides of the curtain 20 along the width direction WW.
[0101] The curtain 20 slides along the width direction WW on opposite sides, corresponding to two slide rails. When the curtain 20 needs to be lowered and unfolded, the curtain support mechanisms 10 on both sides unfold outward. Specifically, the first support member 11 translates along the width direction W, and the second support member 12 rotates to the unfolded position, so that the opposite edges of the curtain 20 slide along the two slide rails to unfold or close, thus achieving stable unfolding of the curtain 20.
[0102] The curtain 20 is generally rectangular or square and descends from the roof of the vehicle. The curtain 20 is typically stored within the roof, so its width is generally the same as the width of the roof. Since the width of the interior space is generally greater than the width of the roof, this can be understood as the vehicle body having a trapezoidal cross-section.
[0103] To address the significant difference between the width of the interior space and the width of the roof, before the curtain 20 lowers, each of the second support members 12 rotates and unfolds towards the center of the vehicle body. When the second support members 12 are in the unfolded position, they are arranged parallel to each other and, for example, vertically, allowing each second support member 12 to correspond and engage with the side edges of the curtain 20, thus enabling the curtain 20 to open and close. The opening and closing direction H of the curtain 20 is as follows: Figure 4 and Figure 5 As shown by H in the diagram, it is in the same direction as the guide rail.
[0104] Based on the aforementioned embodiment, one end of the curtain fabric 20 along the opening / closing direction HH is provided with a winding shaft, and the other end of the curtain fabric 20 along the opening / closing direction HH is provided as a free end. The winding shaft is used to wind the curtain fabric 20 and is installed on the ceiling, while the free end is provided with a pull rod. Both ends of the pull rod are provided with mating parts. Each mating part is slidably arranged corresponding to each slide rail, and the second support member 12 can drive the slide rail to engage or disengage from the mating parts by rotation.
[0105] Specifically, when the curtain 20 needs to be unfolded, the second support member 12 rotates to the unfolded position, allowing the slide rail to engage with the mating member. After engaging with the slide rail, the mating member moves under the guidance of the slide rail, thereby unwinding the curtain 20. When the curtain 20 needs to be rolled up, the roller winds around the curtain 20, and the mating member moves along the slide rail to the top of the slide rail. After the curtain 20 is fully rolled up, the second support member 12 rotates from the unfolded position to the folded position, and the slide rail separates from the mating member.
[0106] In yet another embodiment, this application also provides a vehicle, the vehicle including a vehicle body and a curtain device of any of the above embodiments, the curtain device being disposed on any one side or opposite sides of the vehicle body along the width direction WW.
[0107] The aforementioned means of transportation includes a curtain support mechanism 10. The technical effects are brought about by the curtain support mechanism 10, and the beneficial effects include those of the curtain support mechanism 10, which will not be elaborated here.
[0108] Based on the aforementioned embodiment, the vehicle body is provided with a support member 30, and a first support member 11 is slidably connected to the support member 30 along the width direction W of the vehicle body. A drive mechanism 13 is mounted on the support member 30. When the curtain device is in the working state, both the first support member 11 and the second support member 12 are extended outward. When the curtain device is not in the working state, both the first support member 11 and the second support member 12 are at least partially retracted into the support member 30. Thus, in the non-working state, the first support member 11 and the second support member 12 are hidden, specifically, for example, located in the A-pillar or B-pillar, thereby not occupying interior space and meeting the compact requirements of interior space arrangement.
[0109] In summary, the curtain support mechanism 10, the curtain device, and the vehicle of this application have at least the following advantages:
[0110] 1. Highly integrated storage, significantly saving interior space. After the mechanism is retracted, the first support member 11 and the second support member 12 are in a close-fitting and compact state. The overall thickness is thin and the outline is regular. There are no outward cantilever arms or protrusions that interfere with the design. It can be completely hidden and integrated into the B-pillar of the vehicle body or the interior pillars. It does not encroach on the head space, leg space and effective interior layout space of the occupants, and the space utilization rate is significantly improved.
[0111] 2. Compact and simple structure, high integration, and small space occupation. This mechanism adopts a composite transmission form of motor lead screw + first transmission component 133 + second transmission component 134 + double guide rail slider + wedge inclined plane. The power source, transmission components and actuators are highly integrated, eliminating the need for additional independent drive and complex brackets. The overall structure is simple, with fewer parts and easy to ensure assembly tolerances. It can achieve complete motion function within the limited installation space inside the vehicle, without occupying additional installation space in the body and interior, which is conducive to vehicle lightweighting and cost control.
[0112] 3. Wide range of compatibility, high degree of component versatility and platformization. By adjusting key parameters such as translation stroke S, rotation angle a, angle β, and included angle γ, the curtain unfolding width, shading area, and movement trajectory can be flexibly changed.
[0113] 4. Smooth and synchronized movement, low operating noise, and excellent comfort. Utilizing a single motor to synchronously drive translational and rotational motion, the two movements are coordinated and consistent, with no motion interference or impact. Combined with guide rails and an inclined plane force distribution mechanism, the movement is smooth and stable, effectively reducing abnormal noise and vibration, further enhancing user comfort and a premium feel.
[0114] 5. Controllable unfolding area, enhanced privacy and functionality. The first support member 11 unfolds outward along the width direction W, and the second support member 12 unfolds around the first support member 11, forming a larger and more stable shielding surface, which takes into account multiple functions such as sunshade, privacy separation, rear seat protection, and movie viewing, improving the overall vehicle's intelligent and comfort configuration level.
[0115] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0116] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
