Technical Field

[0002] With the increasing popularity of in-car audio and video entertainment systems, the application scenarios of projection screens in vehicles are constantly expanding. However, in the confined space of a vehicle, the screen is prone to wrinkling when raising and lowering due to structural limitations or uneven force. This can lead to problems such as distorted projected images and difficulty in rewinding, severely restricting the practicality and user experience of in-car projection systems.

[0003] In the related art, a roller tube assembly and an arm assembly are typically used to coordinate the raising and lowering of a curtain.

[0061] With the increasing popularity of in-car audio and video entertainment systems, the application scenarios of projection screens in vehicles are constantly expanding. However, in the confined space of a vehicle, the screen is prone to wrinkling when raising and lowering due to structural limitations or uneven force. This can lead to problems such as distorted projected images and difficulty in rewinding, severely restricting the practicality and user experience of in-car projection systems.

[0062] In the related art, a roller tube assembly and an arm assembly are typically used to coordinate the raising and lowering of a curtain. The roller tube assembly unwinds the curtain, and the arm assembly unfolds the curtain to lower it. The roller tube assembly rewinds the curtain, and the arm assembly folds the curtain to raise it.

[0063] However, due to assembly errors and dimensional deviations, the travel of the roller assembly and the arm assembly cannot be completely consistent, the curtain may have loose wrinkles, or the anti-pinch protection of the arm assembly may be triggered, causing the curtain to fail to rise and fall normally.

[0064] In order to solve the above problems, an embodiment of the present application provides a curtain structure and a vehicle, wherein the curtain structure includes a curtain body; a roller assembly, including a roller body and a first drive member, and the curtain body is wound on the roller body; an arm assembly, and the arm assembly is connected to the free end of the curtain body; an elastic assembly, and the first drive member and the roller body are connected through the elastic assembly, and the first drive member is configured to drive the elastic assembly to rotate, so as to transmit torque to the roller body through the elastic deformation of the elastic assembly, so that the roller body reels or unreels the curtain body, and when reeling, the arm assembly drives the curtain body to rise through a folding movement, and when unreeling, the arm assembly drives the curtain body to fall through an unfolding movement. Through the provision of the elastic assembly, when the curtain body is raised or lowered, the elastic assembly can absorb the travel difference between the roller assembly and the arm assembly through elastic deformation, thereby avoiding the problem of the curtain body being loose and wrinkled and / or the arm assembly triggering the anti-pinch protection and getting stuck.

[0065] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0066] Please refer to Figures 1 to 11 . In the first aspect, the present embodiment provides a curtain structure, including a curtain body 100; a roller tube assembly 200, including a roller tube body 210 and a first driving member 220, the curtain body 100 is wound on the roller tube body 210; an arm assembly 300, the arm assembly 300 is connected to the free end of the curtain body 100; an elastic assembly 400, the first driving member 220 and the roller tube body 210 are connected through the elastic assembly 400, the first driving member 220 is configured to drive the elastic assembly 400 to rotate, so as to transmit torque to the roller tube body 210 through the elastic deformation of the elastic assembly 400, so that the roller tube body 210 reels or unreels the curtain body 100, when reeling, the arm assembly 300 drives the curtain body 100 to rise through a folding motion, and when unreeling, the arm assembly 300 drives the curtain body 100 to descend through an unfolding motion.

[0067] Specifically, the roller tube assembly 200 drives the roller tube body 210 to rotate via the first drive member 220 to achieve the reeling and unreeling of the screen body 100. The arm assembly 300 drives the screen body 100 up and down by unfolding or folding. When the screen body 100 is lowered, if the unwinding stroke of the roller tube assembly 200 is greater than the unfolding stroke of the arm assembly 300, the screen body 100 will be stacked between the roller tube assembly 200 and the arm assembly 300, forming wrinkles. If the unwinding stroke of the roller tube assembly 200 is less than the unfolding stroke of the arm assembly 300, the arm assembly 300 will sense abnormal resistance, triggering the anti-pinch protection function, and preventing the screen body 100 from being lowered smoothly. When the curtain body 100 rises, if the stroke of the curtain body 100 wound by the roller tube assembly 200 is greater than the stroke of the arm assembly 300 folding, the arm assembly 300 will trigger the anti-pinch protection due to abnormal resistance, and the curtain body 100 cannot be smoothly raised. If the stroke of the curtain body 100 wound by the roller tube assembly 200 is less than the stroke of the arm assembly 300 folding, the curtain body 100 will be stacked between the roller tube assembly 200 and the arm assembly 300, thereby forming loose folds.

[0068] Due to the inevitable dimensional and assembly errors during the manufacturing process of the roller tube assembly 200 and the arm assembly 300, the travel of the roller tube assembly 200 and the travel of the arm assembly 300 cannot be completely consistent. In the related art, the unwinding travel of the roller tube assembly 200 is usually greater than the unfolding travel of the arm assembly 300, and the rewinding travel of the roller tube assembly 200 is smaller than the folding travel of the arm assembly 300. This is to avoid the arm assembly 300 triggering the anti-pinch protection, which may prevent the curtain body 100 from being smoothly raised or lowered.

[0069] However, due to the travel difference between the roller tube assembly 200 and the arm assembly 300, the curtain still has loose and wrinkled problems, which affects the user experience.

[0070] To solve the above problems, this embodiment provides a curtain structure, including a curtain body 100 , a roller tube assembly 200 , an arm assembly 300 and an elastic assembly 400 .

[0071] Among them, the roller tube assembly 200 includes a roller tube body 210 and a first driving member 220. The curtain body 100 is wound on the roller tube body 210. The two ends of the elastic component 400 are respectively connected to the first driving member 220 and the roller tube body 210. When the first driving member 220 rotates, the torque of the first driving member 220 is transmitted to the roller tube body 210 through the elastic deformation of the elastic component 400, so that the roller tube body 210 rotates to realize the winding and unwinding of the curtain body 100.

[0072] One end of the arm assembly 300 is connected to the base, and the other end is connected to the free end of the curtain body 100, and drives the curtain body 100 to rise and fall through the unfolding or folding movement.

[0073] When the curtain body 100 needs to be lowered and unfolded, the first driving member 220 drives the roller tube body 210 to rotate in the first direction to unwind the curtain body 100. The arm assembly 300 pulls the free end of the curtain body 100 through the unfolding movement to achieve lowering and unfolding. At this time, since the elastic component 400 is located between the roller tube body 210 and the first driving member 220, the first driving member 220 can transmit torque to the roller tube body 210 through the elastic deformation of the elastic component 400. When the unwinding stroke of the roller tube body 210 for the curtain body 100 is less than the unfolding stroke of the arm assembly 300, the elastic component 400 will be subjected to the tensile force from the arm assembly 300, thereby driving the roller tube body 210 to rotate and release the curtain body 100, thereby avoiding the arm assembly 300 from triggering the anti-pinch protection. When the unwinding stroke of the roller tube body 210 for the curtain body 100 is greater than the unfolding stroke of the arm assembly 300, the elastic assembly 400 can transmit torque to the roller tube body 210 through its own elastic deformation, and thus the entire torque provided by the first driving member 220 will not be immediately transmitted to the roller tube body 210, thereby slowing down the unwinding speed of the roller tube body 210, allowing the curtain body 100 to be smoothly and gradually unwound, ensuring the stability of the curtain during the lifting process and avoiding the formation of wrinkles.

[0074] When the curtain body 100 needs to be raised for retraction, the first drive member 220 drives the roller tube body 210 to rotate in the second direction, thereby retracting the curtain body 100. The arm assembly 300, through a folding motion, pulls the free end of the curtain body 100 to achieve retraction. Accordingly, because the elastic assembly 400 undergoes elastic deformation during the descent and unfolding of the curtain body 100, when the retraction stroke of the roller tube body 210 for retracting the curtain body 100 is less than the folding stroke of the arm assembly 300, the elastic assembly 400 can rely on its own elastic restoring force to drive the roller tube body 210 to rotate faster, thereby absorbing the stroke difference between the first drive member 220 and the arm assembly 300 and preventing the curtain body 100 from becoming loose or wrinkled. When the reeling stroke of the roller tube body 210 for the curtain body 100 is greater than the folding stroke of the arm assembly 300, the elastic assembly 400 will slow down the speed of restoring deformation under the drive of the tensile force of the arm assembly 300, thereby reducing the rotation speed of the roller tube body 210, ensuring that the curtain body 100 can be smoothly and gradually raised and recovered.

[0075] It should be noted that, in this embodiment, the second direction is the opposite direction of the first direction, and unwinding is achieved when the output end of the first driving member 220 rotates along the first direction, and rewinding is achieved when the output end rotates along the second direction.

[0076] By adopting the curtain structure provided in this embodiment, during the process of the curtain body 100 rising and falling, the elastic component 400 enables a flexible connection between the first driving member 220 and the roller tube body 210, and the elastic component 400 absorbs the stroke difference between the first driving member 220 and the arm assembly 300, thereby avoiding the arm assembly 300 triggering the anti-pinch protection or the curtain body 100 becoming loose and wrinkled.

[0077] Please refer to Figures 1 to 11 In an optional embodiment, the elastic component 400 includes a first connecting member 410 connected to the output end of the first driving member 220; a second connecting member 420 connected to the roller body 210; and an elastic member 440, wherein both ends of the elastic member 440 are respectively connected to the first connecting member 410 and the second connecting member 420.

[0078] Specifically, in this embodiment, the elastic assembly 400 includes a first connecting member 410 connected to the output end of the first driving member 220 and a second connecting member 420 connected to the reel body 210. When the output end of the first driving member 220 rotates in a first direction, the elastic member 440 is subjected to a compressive force in the first direction and gradually compresses. At the same time, it transmits the torque transmitted from the first driving member 220 to the reel body 210, thereby driving the reel body 210 to rotate and achieve winding and unwinding.

[0079] In an exemplary embodiment, the elastic member 440 is a coil spring. By adjusting the stiffness and preload of the coil spring and the output torque and rotation speed of the first drive member 220, the energy storage and release process of the coil spring can be precisely controlled to achieve precise adjustment of the rotation speed and force of the roller tube body 210.

[0080] It should also be noted that, in this embodiment, the first driving member 220 is a motor, and one end of the first connecting member 410 is engaged with the output end of the motor, thereby ensuring efficient and stable power transmission between the first driving member 220 and the first connecting member 410. Correspondingly, the second connecting member 420 is engaged with the reel body 210, ensuring efficient and stable power transmission between the second connecting member 420 and the reel body 210.

[0081] In addition, in an optional embodiment, the first connecting member 410 has a first storage cavity, the second connecting member 420 has a second storage cavity, and the elastic member 440 is partially disposed in the first storage cavity, and the other part is disposed in the second storage cavity, thereby preventing dust or other impurities from adhering to the elastic member 440 and affecting the service life of the elastic member 440.

[0082] In an optional embodiment, the elastic component 400 also includes a first rotating shaft 430, which is located between the first connecting member 410 and the second connecting member 420. The elastic member 440 is sleeved on the first rotating shaft 430, and the two ends of the elastic member 440 are respectively connected to the first connecting member 410 or the second connecting member 420.

[0083] Specifically, since the elastic member 440 needs to absorb the travel difference between the first driving member 220 and the arm assembly 300, the elastic member 440 should not be made of a material with a large elastic coefficient. As a result, when the screen body 100 is hovering after being lowered and unfolded, due to the bumps of the vehicle or external forces, the screen body 100 is prone to vibrate due to inertial relaxation, and even cause wrinkles to accumulate, resulting in distortion of the projected image, which greatly reduces the user experience.

[0084] Therefore, to solve the above problems, the elastic component 400 in this embodiment further includes a first rotating shaft 430, which is arranged between the first connecting member 410 and the second connecting member 420. The elastic member 440 is sleeved on the first rotating shaft 430, and the two ends of the elastic member 440 are respectively connected to the first connecting member 410 and the second connecting member 420. When the screen body 100 needs to hover, the first driving member 220 drives the elastic member 440 to rotate and tighten it to the first rotating shaft 430, so that a rigid connection is formed between the first driving member 220 and the roller body 210, thereby making the screen structure a stable whole. When the screen body 100 is subjected to external force, the vibration energy can be dispersed to the entire screen structure, thereby reducing the vibration amplitude of the screen body 100, avoiding large fluctuations of the screen body 100, and even causing wrinkles to accumulate and cause distortion of the projection image, thereby ensuring the user experience.

[0085] Meanwhile, when the curtain body 100 is in the process of rising or falling, the diameter of the elastic member 440 is larger than the diameter of the rotating shaft 430 . Therefore, the first connecting member 410 and the second connecting member 420 are flexibly connected via the elastic member 440 .

[0086] Specifically, in this embodiment, since the elastic member 440 is sleeved on the first rotating shaft 430, when the elastic member 440 is gradually compressed, the diameter of the elastic member 440 will also gradually decrease until it is tightened on the first rotating shaft 430, thereby realizing a rigid connection between the first connecting member 410 and the second connecting member 420 through the setting of the elastic member 440 and the first rotating shaft 430, thereby realizing a rigid connection between the first driving member 220 and the roller body 210.

[0087] That is, in this embodiment, the elastic component 400 can be switched between the flexible state and the rigid state by driving the first driving member 220 .

[0088] For example, when the curtain body 100 needs to be extended to 80% of its original length, the arm assembly 300 extends to a preset stroke and then stops, and the first drive member 220 rotates to a preset stroke and then stops. At this point, if the elastic assembly 400 is still in a flexible state, when the curtain body 100 is subjected to wind or vehicle turbulence, the elastic assembly 400 will be compressed, causing the roller tube body 210 to rotate and unwind to a certain extent, which may cause the curtain body 100 to loosen or wrinkle. Therefore, when the curtain body 100 is hovering, the first drive member 220 switches the elastic assembly 400 from a flexible state to a rigid state, i.e., rigidly connecting the first drive member 220 to the roller tube body 210. At this point, even if the curtain body 100 is subjected to wind or other external forces, the roller tube body 210 will not rotate due to the restraint of the first drive member 220, thereby ensuring the stability of the curtain body 100 while hovering.

[0089] The working principle of the elastic component 400 during the ascending and descending process of the curtain body 100 will be further described below in conjunction with the specific structure of the elastic component 400 provided in this embodiment.

[0090] Specifically, when the curtain body 100 begins to descend and unfold from the initial wound state, the output end of the first driving member 220 rotates in the first direction, and drives the elastic member 440 to be compressed in the first direction through the first connecting member 410. At the same time, the elastic member 440 drives the roller tube body 210 to rotate through the second connecting member 420. At this time, the diameter of the elastic member 440 is larger than the outer diameter of the first rotating shaft 430 and is in a flexible state, thereby making the first driving member 220 and the roller tube body 210 flexibly connected. The arm assembly 300 stretches the free end of the curtain body 100 to make the curtain body 100 descend and gradually unfold. Then, the elastic member 440 can absorb the stroke difference between the first driving member 220 and the arm assembly 300, thereby ensuring the stable unfolding of the curtain body 100 and avoiding wrinkles. When the curtain body 100 descends and unfolds to the preset position, the arm assembly 300 stops moving, and the output end of the first driving member 220 rotates along the second direction, thereby gradually restoring the elastic deformation of the elastic member 440, causing the elastic member 440 to be compressed along the second direction and gradually tightened on the first rotating shaft 430, so that a rigid connection is formed between the first driving member 220 and the roller tube body 210, and the rigid connection prevents the roller tube body 210 from rotating unexpectedly, thereby ensuring the stability of the curtain body 100.

[0091] In addition, in an optional embodiment, the size specifications and materials of the elastic member 440 can be adaptively selected in advance so that when the curtain body 100 is lowered and unfolded to a preset position, the elastic member 440 is correspondingly tightened on the first rotating shaft 430, thereby achieving direct switching between the flexible state and the rigid state without the need to additionally rotate the output end of the first driving member 220 in the opposite direction.

[0092] At the same time, it should be noted that due to the limitations of dimensional tolerances and assembly tolerances, it is impossible to ensure that the elastic member 440 is in a tightened state when the curtain body 100 is lowered to the preset position. Therefore, those skilled in the art can adaptively adjust the elastic member 440 to be tightened on the first rotating shaft 430 before the curtain body 100 is fully opened. In other words, the curtain body 100 can be in a flexible state during the front part of the process of lowering and unfolding, and in a rigid state during the rear part of the process. In this regard, this embodiment does not impose any restrictions, and those skilled in the art can make adaptive choices. For example, when the curtain body 100 is lowered and unfolded to 80% or less of its full opening, the elastic component 400 is in a flexible state, and when the curtain body 100 is lowered and unfolded to 80% or less of its full opening, the elastic component 400 is in a rigid state.

[0093] By adopting the screen structure provided in this embodiment, during the rising and falling process of the screen body 100, the elastic component 400 absorbs the travel difference between the first driving member 220 and the arm assembly 300, thereby avoiding the problem of the arm assembly 300 triggering the anti-pinch protection or the screen body 100 wrinkling. When the screen body 100 is hovering, the first driving member 220 switches the elastic component 400 to a rigid state, thereby ensuring that the screen body 100 is stably tensioned in the hovering state.

[0094] Please refer to Figures 1 to 11 In an optional embodiment, one end of the first rotating shaft 430 is connected to the first connecting member 410, and the other end is movably connected to the second connecting member 420, or

[0095] One end of the first rotating shaft 430 is connected to the second connecting member 420 , and the other end is movably connected to the first connecting member 410 .

[0096] In this embodiment, one end of the first rotating shaft 430 connected to the first connecting member 410 is rigidly connected, and the other end connected to the second connecting member 420 is rotationally connected, so that when the elastic member 440 is not tightened on the first rotating shaft 430, a flexible connection is achieved between the first connecting member 410 and the second connecting member 420 through the elastic member 440.

[0097] In another optional embodiment, one end of the first rotating shaft 430 connected to the first connecting member 410 is a rotating connection, and the end connected to the second connecting member 420 is a rigid connection, so that when the elastic member 440 is not tightened on the first rotating shaft 430, a flexible connection is achieved between the first connecting member 410 and the second connecting member 420 through the elastic member 440.

[0098] By adopting the curtain structure provided in this embodiment, the two ends of the first rotating shaft 430 are movably connected or rigidly connected to the first connecting member 410 and the second connecting member 420 respectively, which can prevent the first rotating shaft 430 from falling off and improve the strength of the rigid connection.

[0099] Please refer to Figures 1 to 11 In an optional embodiment, the elastic assembly 400 further includes at least one first limiting member 450 disposed on the first connecting member 410; at least one second limiting member 460 disposed on the second connecting member 420; the first driving member 220 is configured to drive the first connecting member 410 to rotate so that the first limiting member 450 and the second limiting member 460 abut or disengage.

[0100] When the first limiting member 450 abuts against the second limiting member 460 , the elastic assembly 400 is in a rigid state, and the arm assembly 300 drives the curtain body 100 to hover at the current position;

[0101] When the first limiting member 450 and the second limiting member 460 are disengaged, the elastic component 400 is in a flexible state, the first driving member 220 and the roller tube body 210 transmit torque through the elastic deformation of the elastic component 400, and the arm assembly 300 drives the curtain body 100 to rise and fall through the unfolding or folding movement.

[0102] Specifically, in this embodiment, the first stopper 450 is disposed on the side of the first connecting member 410 facing the second stopper 460, and the second stopper 460 is disposed on the side of the second connecting member 420 facing the first stopper 450. When the curtain body 100 begins to descend and unfold from an initially wound state, the first driving member 220 preferentially rotates in the second direction, causing the first stopper 450 and the second stopper 460 to abut against each other. The first driving member 220 then rotates in the first direction to unwind the curtain, and the arm assembly 300 unfolds to stretch the curtain body 100, thereby lowering and unfolding the curtain body 100. By rotating the first driving member 220 in the second direction before unwinding, the stroke difference between the first driving member 220 and the arm assembly 300 that can be absorbed by the elastic component 400 is the maximum value, that is, the stroke between the state where the first limiting member 450 abuts against the second limiting member 460 along the second direction to the state where the first limiting member 450 abuts against the second limiting member 460 along the first direction, thereby ensuring that the elastic component 400 can fully absorb the stroke difference between the first driving member 220 and the arm assembly 300, thereby avoiding the problem of looseness and wrinkles in the curtain body 100.

[0103] At the same time, by abutting the first and second stoppers 450 and 460, the first drive member 220 and the roller body 210 are rigidly connected, fully ensuring the strength of the rigid connection and, in turn, the tension of the screen body 100, forming a stable, integrated screen structure. When the screen body 100 is subjected to external forces, the vibration energy is dispersed throughout the entire screen structure, thereby reducing the vibration amplitude of the screen body 100 and preventing large fluctuations in the screen body 100, which could lead to wrinkles and distortion of the projected image, thereby ensuring a superior user experience.

[0104] In addition, those skilled in the art can adaptively select the specific structure of the first limiting member 450 and the second limiting member 460 according to actual needs, and this embodiment does not impose any limitation on this. For example, the first limiting member 450 and the second limiting member 460 can be blocks.

[0105] In an exemplary embodiment, the first limiting member 450 has two clamping portions, and the second limiting member 460 has two clamping grooves. When the first limiting member 450 and the second limiting member 460 abut against each other along the first direction, one of the clamping portions is inserted into one of the clamping grooves. When the first limiting member 450 and the second limiting member 460 abut against each other along the second direction, the other clamping portion is inserted into the other clamping groove, thereby further improving the strength of the rigid connection.

[0106] In addition, in an optional embodiment, the number of the first limit members 450 and the second limit members 460 are both two, one first limit member 450 and one second limit member 460 form a group, and the two groups are arranged at intervals in the circumferential direction of the first rotating shaft 430, so that when the elastic component 400 is in a rigid state, each group of the first limit members 450 and the second limit members 460 can achieve abutment, thereby further ensuring the stability of the rigid connection between the first driving member 220 and the roller tube body 210.

[0107] Those skilled in the art can adaptively select the size of the first stopper 450 and the second stopper 460, as well as the spacing therebetween, to adjust the maximum value that the elastic assembly 400 can absorb the travel difference between the first driving member 220 and the arm assembly 300. For example, based on the 360° circumference of the first rotating shaft 430, the angles occupied by the first stopper 450 and the second stopper 460 are both 20°, and the spacing therebetween is 70°.

[0108] Please refer to Figures 1 to 11In an optional embodiment, the elastic component 400 further includes a plurality of shock absorbers 470 , each of which is disposed outside the first limiting member 450 and the second limiting member 460 , and the stiffness of the shock absorber 470 is less than that of the first limiting member 450 and the second limiting member 460 .

[0109] Specifically, in this embodiment, the first stopper 450 and the second stopper 460 inevitably collide when they abut against each other, causing the roller tube body 210 to vibrate, resulting in shaking or abnormal noise in the curtain body 100. Therefore, the elastic assembly 400 in this embodiment also includes a plurality of shock absorbers 470, the number of which is equal to the sum of the number of the first stopper 450 and the second stopper 460. By sleeved over the first stopper 450 and the second stopper 460, the shock absorbers 470 are eliminated from the rigid collision between the first stopper 450 and the second stopper 460, thereby preventing shaking or abnormal noise in the curtain body 100.

[0110] In this embodiment, the shock absorbing member 470 is sleeved on the circumference of the first limiting member 450 and the second limiting member 460 to ensure the stability of the fixing of the shock absorbing member 470 .

[0111] In other embodiments, the shock absorbing member 470 may also be disposed only on the side where the first limiting member 450 and the second limiting member 460 abut against each other. This embodiment does not impose any limitation on this.

[0112] The shock absorber 470 can be made of rubber or other vibration-absorbing materials. The shock absorber 470 can be integrally formed with the first stopper 450 and the second stopper 460, or can be manufactured separately from the first stopper 450 and the second stopper 460. By making the stiffness of the shock absorber 470 smaller than that of the first stopper 450 and the second stopper 460, shaking or abnormal noise of the screen body 100 can be further prevented. The specific material and manufacturing process of the shock absorber 470 can be selected by those skilled in the art based on actual needs, and this embodiment does not impose any restrictions on this.

[0113] In an optional embodiment, the roller assembly 200 also includes a support seat 250; a second rotating shaft 260 is rotatably arranged on the support seat 250, and the second rotating shaft 260 is connected to the end of the roller body 210 facing away from the elastic component 400; a third limiting member 270 is arranged to pass through the support seat 250 and the second rotating shaft 260 in sequence to limit the rotation of the second rotating shaft 260.

[0114] Specifically, during pre-installation, the elastic component 400 may be pre-tightened to a certain extent, thereby providing a certain degree of tension to the curtain body 100 in the initial state.

[0115] Specifically, when the elastic component 400 is pre-installed, the third limit member 270 is sequentially passed through the support seat 250 and the second rotating shaft 260 to limit the rotation of the second rotating shaft 260, thereby limiting the rotation of the roller body 210, thereby preventing the roller body 210 from rotating under the elastic restoring force of the elastic component 400, causing the pre-tightening to fail.

[0116] In an optional embodiment, the third limiting member 270 is a pin. By inserting the pin into the support seat 250 and the second rotating shaft 260, the rotation of the second rotating shaft 260 can be limited. In other embodiments, the structure of the third limiting member 270 can also be adaptively selected according to actual needs, and this embodiment does not impose any restrictions on this.

[0117] In an optional embodiment, the curtain structure further includes an adapter 500, which includes a first plug-in end 510 and a second plug-in end 520. The first plug-in end 510 is engaged with the elastic component 400, and the second plug-in end 520 is engaged with the roller body 210 to transmit the movement of the elastic component 400 to the roller body 210.

[0118] Specifically, in this embodiment, the first plug end 510 is engaged with the elastic component 400, and the second plug end 520 is engaged with the roller body 210, thereby forming a rigid connection between the elastic component 400 and the roller body 210, ensuring a stable connection between the elastic component 400 and the roller body 210, and at the same time enabling the torque transmitted from the elastic component 400 to be accurately transmitted to the roller body 210 through the adapter 500, thereby ensuring the stability of the curtain body 100 during lifting and lowering.

[0119] In this embodiment, the first plug-in end 510 is a flat key, and the second plug-in end 520 is a keyway. By inserting the first plug-in end 510 into the end of the elastic component 400 close to the roller body 210, the movement of the elastic component 400 is transmitted to the adapter 500. By inserting the end of the roller body 210 close to the elastic component 400 into the second plug-in end 520, the movement of the adapter 500 is transmitted to the roller body 210, thereby realizing the rotation of the roller body 210.

[0120] In other embodiments, the specific structures of the first plug end 510 and the second plug end 520 can also be adaptively selected according to actual needs, and this embodiment does not impose any restrictions on this. For example, the first plug end 510 and the second plug end 520 are both splines.

[0121] In an optional embodiment, the arm assembly 300 includes at least one connecting rod mechanism 310, the connecting rod mechanism 310 includes a second driving member 311, which is arranged on the base; a joint member 312, which is connected to the output end of the second driving member 311, a first connecting rod 313, one end of which is hinged to the base, and the other end is connected to the joint member 312; a second connecting rod 314, one end of which is connected to the curtain body 100, and the other end is connected to the joint member 312, and the second driving member 311 is configured to drive the joint member 312 to rotate to drive the first connecting rod 313 and the second connecting rod 314 to fold or unfold with each other.

[0122] The base is the basic structure of the entire curtain structure, and the roller body and elastic components are both arranged on the base.

[0123] Specifically, in this embodiment, the connecting rod mechanism 310 includes a second driving member 311 arranged on the base, and the output end of the second driving member 311 is connected to the joint member 312, so that the joint member 312 can be driven to rotate to drive the first connecting rod 313 and the second connecting rod 314 to fold or unfold with each other.

[0124] Specifically, in this embodiment, the two ends of the joint part 312 can rotate back and forth around its own rotation center under the drive of the second driving member 311, the first connecting rod 313 is connected to one end of the joint part 312, and the second connecting rod 314 is connected to the other end of the joint part 312, so as to drive the first connecting rod 313 and the second connecting rod 314 to fold or unfold by changing the opening angle between them by controlling the rotation of the two ends of the joint part 312.

[0125] Among them, when the opening angle between the first link 313 and the second link 314 becomes larger, the second link 314 descends in the direction away from the base, thereby driving the curtain body 100 to descend and unfold; when the opening angle between the first link 313 and the second link 314 is 180°, the curtain body 100 descends to a fully open state; when the opening angle between the first link 313 and the second link 314 decreases, the second link 314 rises in the direction close to the base, thereby driving the curtain body 100 to rise; when the first link 313 and the second link 314 are close to each other, the curtain body 100 rises to a fully retracted state.

[0126] In this embodiment, the joint 312 is provided to drive the first connecting rod 313 and the second connecting rod 314 to move, thereby ensuring stability during the lifting process.

[0127] In addition, it should be noted that in this embodiment, the number of connecting rod assemblies can be two, and the two connecting rod assemblies are relatively arranged on both sides of the base, so as to synchronously control the rise and fall of the curtain body 100 from both sides, ensuring the stability of the curtain body 100 during lifting and lowering.

[0128] In an optional embodiment, the joint member 312 includes a rotating rod, one end of which is connected to the first connecting rod 313, and the other end is connected to the output end of the second driving member 311, and the second driving member 311 is configured to drive the rotating rod to rotate; a rotating wheel, which is engaged with the rotating rod, and the second connecting rod 314 is connected to the rotating wheel.

[0129] Specifically, in this embodiment, the rotating wheel and the rotating rod are engaged with each other. When the second driving member 311 drives the rotating rod to rotate, the rotating wheel will rotate with the rotation of the rotating rod, thereby controlling the angle change between the first connecting rod 313 and the second connecting rod 314, thereby realizing the expansion and folding of the connecting rod mechanism 310.

[0130] In this embodiment, the rotating wheel is a worm wheel, and the rotating rod is a worm, and the worm wheel and worm are matched to ensure the stability of the transmission.

[0131] In addition, it should be noted that, since the rotating wheel and the rotating rod are engaged with each other, when the second driving member 311 stops and causes the screen body 100 to hover, even if the screen body 100 is subjected to external force or other external factors, the rotating wheel and the rotating rod are engaged with each other, so that the rotating rod will not undergo an unexpected rotation corresponding to the direction of the external force, thereby ensuring the stability of the connecting rod mechanism 310 in stretching the screen body 100.

[0132] In an optional embodiment, the curtain structure further includes a cover plate 700 and a shell 600, wherein a receiving cavity 610 is formed in the shell 600, wherein the roller tube assembly 200 and the elastic assembly 400 are both disposed in the receiving cavity 610, and the cover plate 700 is connected to the free end of the curtain body 100, and the arm assembly 300 drives the cover plate 700 to open or close the receiving cavity 610 through an unfolding or folding movement.

[0133] Specifically, in this embodiment, a housing 600 defines a receiving cavity 610 for accommodating the roller tube assembly 200 and the elastic assembly 400. When the arm assembly 300 is folded and the screen body 100 is retracted, both the arm assembly 300 and the screen body 100 are located within the receiving cavity 610. When the roller tube 210 is unwound and the screen body 100 is extended and stretched, the cover plate 700, connected to the free end of the screen body 100, is driven by the arm assembly 300 to move away from the housing 600, thereby opening the housing 600 and facilitating the extension of the arm assembly 300 and the screen body 100.

[0134] By providing the cover plate 700 and the housing 600 , it is prevented that external dust or other impurities enter the accommodating cavity 610 and affect the normal operation of the curtain structure, thereby ensuring the service life of the curtain structure.

[0135] In an optional embodiment, a sealing member is provided on the peripheral side of the cover plate. When the cover plate is closed on the shell, the sealing member is squeezed between the cover plate and the shell, thereby ensuring the tightness of the cover plate sealing.

[0136] In an optional embodiment, the cover plate is directly connected to the arm assembly 300 , so that the cover and the opening are directly driven by the arm assembly 300 .

[0137] In an optional embodiment, the roller tube assembly 200 further includes a fourth limiting member 230 and at least one fastener 240. The fourth limiting member 230 has at least one limiting hole. The fastener 240 passes through the limiting hole to sequentially connect the fourth limiting member 230, the curtain body 100 and the roller tube body 210.

[0138] Specifically, in this embodiment, the fourth limiting member 230 is matched with the roller tube body 210. The fourth limiting member 230 is used to press the fixed end of the curtain body 100 onto the roller tube body 210, and the fastener 240 passes through the limiting hole on the fourth limiting member 230 to fix the curtain body 100 to the roller tube body 210, thereby ensuring the stability of the fixing of the curtain body 100 and preventing the curtain body 100 from separating from the roller tube body 210 when the tension is large.

[0139] For example, the fastener 240 may be a screw, and the curtain body 100 is fixed by screwing the screw onto the roller tube body 210 .

[0140] Meanwhile, it should be noted that those skilled in the art can adaptively select the number of the limiting holes and the fasteners 240 according to actual needs, and this embodiment does not impose any limitation on this.

[0141] In a second aspect, this embodiment provides a vehicle, comprising a vehicle body and the curtain structure described in any one of the first aspects, wherein the curtain structure is disposed in the vehicle body.

[0142] The specific structure of the curtain structure has been described in the above embodiments and will not be repeated here.

[0143] The vehicle provided in this embodiment includes a vehicle body and the curtain structure described in any one of the first aspects, wherein the curtain structure is arranged in the vehicle body. The curtain structure includes a curtain body 100; a roller assembly 200 including a roller body 210 and a first driving member 220, wherein the curtain body 100 is wound around the roller body 210; an arm assembly 300, wherein the arm assembly 300 is connected to the free end of the curtain body 100; an elastic assembly 400, wherein the first driving member 220 and the roller body 210 are connected via the elastic assembly 400, and the first driving member 220 is configured to drive the elastic assembly 400 to rotate, so as to transmit torque to the roller body 210 through the elastic deformation of the elastic assembly 400, so that the roller body 210 reels or unreels the curtain body 100, and the arm assembly 300 drives the curtain body 100 to rise and fall through the unfolding or folding movement. By setting the elastic component 400, when the screen body 100 is raised or lowered, the elastic component 400 can absorb the travel difference between the roller tube assembly 200 and the arm assembly 300 through elastic deformation, thereby avoiding the problem of wrinkles in the screen body 100 or the arm assembly 300 triggering the anti-pinch protection and getting stuck.

[0144] Finally, it should be noted that those skilled in the art will readily identify other embodiments of the present invention after considering the specification and practicing the invention disclosed herein.
