[0053] As Figure 1 and Figure 2 The present application provides a roller shutter structure 100, which comprises a plurality of roller shutter sheets 10 and sealing members 20 connected in sequence. The sealing member 20 is located between two adjacent roller shutter sheets 10, and the sealing member 20 is connected with the two adjacent roller shutter sheets 10 respectively.

[0054] The sealing member 20 connects two adjacent roller shutter sheets 10 together, has an auxiliary connection effect on the two adjacent roller shutter sheets 10, and reduces the problem of loose connection between the two adjacent roller shutter sheets 10 during use.

[0055] During use of the roller shutter structure 100, vibration may occur. The sealing member 20 connects the adjacent roller shutter sheets 10, so that the entire roller shutter structure 100 forms an organic whole, can effectively resist continuous vibration, reduce damage of the roller shutter sheets 10 due to mutual displacement and loosening, and prolong the service life of the roller shutter structure 100.

[0056] It should be noted that the roller shutter sheets 10 connected in sequence are in one direction, and the roller shutter sheets 10 are connected end to end.

[0057] The embodiments of the present application will be described in detail below with reference to the accompanying drawings, and before the embodiments of the present application are described in detail, the application scenarios of the embodiments of the present application are first introduced.

[0058] The present application provides a vehicle, which comprises a roller shutter structure 100.

[0059] Exemplarily, the vehicle provided by the present application includes but is not limited to a pickup truck, a van, a camping car, and a special vehicle.

[0060] Take a pickup truck as an example, when the roller shutter structure 100 is installed above the pickup truck cargo box, a plurality of sequentially connected roller shutter sheets 10 can be unfolded and folded by manual or electric drive. The sealing element 20 reduces the close fit between adjacent roller shutter sheets 10, reduces the gap, and can block the invasion of dust, sand, rainwater and other external impurities into the cargo box, protecting the goods from erosion.

[0061] The roller shutter structure 100 provided by the application can also be used for a roller shutter door.

[0062] As shown in Figure 3 and Figure 4 , in a possible implementation, the roller shutter sheet 10 includes a main body part 11, a first bending part 12 and a second bending part 13. The first bending part 12 and the second bending part 13 are respectively arranged at both ends of the main body part 11 and connected with the main body part 11. The sealing element 20 is connected with the first bending part 12 of one of the two adjacent roller shutter sheets 10 and connected with the second bending part 13 of the other of the two adjacent roller shutter sheets 10.

[0063] The roller shutter sheet 10 is provided with the first bending part 12 and the second bending part 13, which provide a more stable force point for the sealing element 20, so that the sealing element 20 is more closely connected with the first bending part 12 and the second bending part 13, and the connection effect of the sealing element 20 connecting the two adjacent roller shutter sheets 10 is improved.

[0064] Meanwhile, the sealing element 20 can tightly lock the gap between the adjacent roller shutter sheets 10, improve the sealing effect, and further improve the resistance to external invasion of dust, rainwater, sand and the like.

[0065] In the use process of the roller shutter structure 100, when the roller shutter structure 100 is impacted, the first bending part 12 and the second bending part 13 as the key parts connected with the sealing element 20 can effectively disperse the external force along the main body part 11 of the roller shutter sheet 10. The sealing element 20 acts as a buffer element to coordinate the stress of the adjacent roller shutter sheets 10, so as to avoid stress concentration at a certain point and cause damage and deformation of the roller shutter sheet 10, protect the mechanical integrity of the entire roller shutter structure 100, and maintain its long-term stable operation.

[0066] In a possible implementation, referring to Figure 3 and Figure 4 , a first clamping groove 121 is formed between the first bending part 12 and the main body part 11. A second clamping groove 131 is formed between the second bending part 13 and the main body part 11. A part of the sealing element 20 is clamped in the first clamping groove 121, and another part of the sealing element 20 is clamped in the second clamping groove 131.

[0067] The sealing element 20 is embedded in the first and second clamping grooves 121 and 131, thereby achieving the embedded connection of the sealing element 20 and the roller shutter sheet 10. The risk of the sealing element 20 being pulled out of the first clamping groove 121 is reduced, thereby improving the stability of the sealing element 20 in the structure of the roller shutter sheet 10.

[0068] The structure of the first and second clamping grooves 121 and 131 improves the installation accuracy and reduces the installation difficulty, thereby facilitating the installation. Specifically, the sealing element 20 only needs to be inserted into the first and second clamping grooves 121 and 131 in sequence, which is simple to operate. The sealing element 20 can be installed in place without complex calibration procedures, thereby shortening the assembly time of the single roller shutter sheet 10 and the sealing element 20, and further improving the production efficiency of the entire roller shutter structure 100.

[0069] When the roller shutter structure 100 encounters external force impact, such as strong wind lateral pulling during high-speed driving of a vehicle, or accidental bumping during loading and unloading of goods, the clamping groove can assist the sealing element 20 to share and buffer the external force by virtue of its structural rigidity, uniformly dispersing the impact force to the main body of the roller shutter sheet 10, avoiding damage to the sealing element 20 due to excessive local stress, and improving the reliable operation of the entire roller shutter system under complex working conditions.

[0070] In one possible implementation, referring to Figure 3 and Figure 4 The first bending part 12 includes a first extension part 122 and a second extension part 123 connected to each other, the first extension part 122 extends away from the main body part 11, and the second extension part 123 extends toward the main body part 11, and the first extension part 122 and the second extension part 123 form the first clamping groove 121 with the main body part 11.

[0071] Through the above arrangement, a suitable angle is provided for the sealing element 20 to be embedded in the first clamping groove 121, thereby facilitating the installation.

[0072] Meanwhile, the first clamping groove 121 formed by the first extension part 122 and the second extension part 123 can tightly fit with the sealing element 20, thereby restricting the sealing element 20 from rotating, tilting, and other unstable conditions in the clamping groove, further improving the stability of the sealing element 20 in the clamping groove, and improving the connection effect of the sealing element 20.

[0073] When the roller shutter structure 100 encounters rainwater, the sealing element 20 can reduce the situation of rainwater entering the inside of the roller shutter structure 100.

[0074] The first extension 122 extends away from the main body 11, effectively intercepts the rainwater flowing to the main body of the roller blind sheet 10, and guides the rainwater to flow into the first clamping groove 121. The second extension 123 extends towards the main body 11, cooperates with the main body 11 to form a water guide path, and enables the rainwater to be smoothly discharged along the first clamping groove 121, reducing the accumulation of rainwater between the roller blind sheets 10.

[0075] When a small amount of rainwater enters through the gap between the sealing element 20 and the roller blind sheet 10, the rainwater needs to flow through at least the first extension 122 and the second extension 123. The first extension 122 and the second extension 123 increase the path of the rainwater, thereby improving the waterproof effect.

[0076] In one possible implementation, referring to Figure 3 and Figure 4 The sealing element 20 includes a first recess 21. The first bent portion 12 includes a first protrusion 124, which is arranged at an end of the second extension 123 away from the first extension 122 and connected to the second extension 123. When the sealing element 20 is clamped in the first clamping groove 121, the first protrusion 124 is located in the first recess 21.

[0077] When the sealing element 20 is clamped in the first clamping groove 121, the positioning accuracy of the sealing element 20 in the clamping groove is improved. The connection between the sealing element 20 and the first bent portion 12 is also more stable. The possible slight gap is effectively filled.

[0078] The first protrusion 124 and the first recess 21 form a anti-disengagement locking structure. This can reduce the accidental disengagement of the sealing element 20 from the clamping groove due to vehicle vibration, external force pulling and other factors during use. Even in extreme working conditions, such as off-road driving of a pickup truck on a bumpy road section, the sealing element 20 can still be fixed in the clamping groove, ensuring that the roller blind structure 100 maintains good sealing performance and reducing the maintenance frequency caused by the disengagement of the sealing element 20.

[0079] The second bent portion 13 includes a third extension 132 and a fourth extension 133 connected to each other. The third extension 132 extends away from the main body 11, and the fourth extension 133 extends towards the main body 11. The third extension 132, the fourth extension 133 and the main body 11 enclose the second clamping groove 131.

[0080] The above arrangement provides a suitable angle for the sealing element 20 to be embedded in the second clamping groove 131, facilitating installation.

[0081] Meanwhile, the second clamping groove 131 formed by the third extension 132 and the fourth extension 133 can be tightly fitted with the sealing piece 20, and the sealing piece 20 can be constrained from multiple angles to reduce the instability of the sealing piece 20 in the clamping groove, such as rotation, tilting, etc., thereby further improving the stability of the sealing piece 20 in the clamping groove and improving the connection effect of the sealing piece 20.

[0082] When the roller shutter structure 100 encounters rain, the sealing piece 20 can reduce the situation that rainwater enters the inside of the roller shutter structure 100.

[0083] The third extension 132 extends away from the main body 11, can effectively intercept rainwater flowing to the main body of the roller shutter sheet 10, and guide the rainwater to flow into the second clamping groove 131. The fourth extension 133 extends toward the main body 11, and forms a water guide path together with the main body 11, so that the rainwater can be smoothly drained along the second clamping groove 131, and the situation that rainwater accumulates between the roller shutter sheets 10 is reduced.

[0084] When a small amount of rainwater enters through the gap between the sealing piece 20 and the roller shutter sheet 10, the rainwater needs to flow through at least the third extension 132 and the fourth extension 133 of the sealing piece 20, and the third extension 132 and the fourth extension 133 increase the path of the rainwater, thereby improving the waterproof effect.

[0085] In a possible implementation, referring to Figure 3 and Figure 4 The sealing piece 20 comprises a second recess 22. The second bending part 13 comprises a second protrusion 134, which is arranged at an end of the fourth extension 133 away from the third extension 132 and connected with the fourth extension 133. When the sealing piece 20 is clamped in the second clamping groove 131, the second protrusion 134 is located in the second recess 22.

[0086] When the sealing piece 20 is clamped in the second clamping groove 131, the positioning accuracy of the sealing piece 20 in the second clamping groove 131 is improved. The connection between the sealing piece 20 and the second bending part 13 is also more stable. The possible slight gap is effectively filled.

[0087] The second protrusion 134 and the second recess 22 form a anti-disengagement locking structure. This can reduce the situation that the sealing piece 20 is accidentally disengaged from the clamping groove due to vehicle vibration, external force pulling and other factors during use. Even in extreme working conditions, such as when a pickup truck drives on a rough road, the sealing piece 20 can still be fixed in the clamping groove, ensuring that the roller shutter structure 100 maintains good sealing performance and reducing the maintenance frequency caused by the disengagement of the sealing piece 20.

[0088] In a possible implementation, referring toFigure 3 and Figure 4 The first bending part 12 and the second bending part 13 are located on the first side of the main body part 11.

[0089] The same-side arrangement of the first bending part 12 and the second bending part 13 can reduce space occupation, thereby improving space utilization.

[0090] The same-side arrangement of the first bending part 12 and the second bending part 13 makes the appearance of the roller blind sheet 10 more concise and unified, thereby improving visual effect.

[0091] In a possible implementation, referring to Figure 3 and Figure 4 The roller blind sheet 10 comprises a connecting structure 30. The main body parts 11 of two adjacent roller blind sheets 10 are connected through the connecting structure 30; the sealing member 20 is located on the side of the connecting structure 30 away from the main body part 11 and on the first side of the main body part 11.

[0092] The main body parts 11 of adjacent roller blind sheets 10 are connected through the connecting structure 30, thereby improving the connecting strength between the roller blind sheets 10.

[0093] The sealing member 20 is arranged on the side of the connecting structure 30 away from the main body part 11 and on the first side of the main body part 11, which does not interfere with the mechanical performance of the connecting structure 30 and can reduce space occupation.

[0094] The sealing member 20 is arranged on the side of the connecting structure 30 away from the main body part 11 and on the first side of the main body part 11, which does not have exposed sealing member 20 disorder lines or connection abruptness, making the appearance of the roller blind sheet 10 more neat and concealed, thereby improving visual effect.

[0095] In a possible implementation, referring to Figure 3 and Figure 4 The sealing member 20 comprises a third recessed part 23, and the connecting structure 30 is located in the third recessed part 23.

[0096] The connecting structure 30 is located in the third recessed part 23 of the sealing member 20, and the sealing member 20 has a certain limiting effect on the connecting structure 30. In this way, the connecting structure 30 can be physically better fixed and protected, and the connecting structure 30 can be prevented from being separated from the original position due to external force pulling, vibration and other factors.

[0097] The connecting structure 30 is located in the third recessed part 23 of the sealing member 20, so that the sealing member 20 has a wrapping effect on the connecting structure 30, forming a continuous and seamless waterproof barrier, thereby reducing the rainwater entering the first side of the roller blind structure 100.

[0098] The third recess 23 can also guide the flow of rainwater. When there is water accumulation on the surface of the roller blind sheet 10, the recess can orderly drain the rainwater to the designated direction like a micro water tank. This effectively prevents the accumulation of rainwater at the connection part of the roller blind sheet 10, further reducing the risk of rainwater penetration.

[0099] At the same time, the third recess 23 increases the distance of rainwater entering the first side space of the roller blind structure 100, thereby improving the waterproof effect.

[0100] In a possible implementation, referring to Figure 3 and Figure 4 The connecting structure 30 includes a first connecting piece 31 and a second connecting piece 32. The first connecting piece 31 is arranged at one end of the main body part 11. The second connecting piece 32 is arranged at the other end of the main body part 11, and the second connecting piece 32 can be connected with the first connecting piece 31.

[0101] The first connecting piece 31 and the second connecting piece 32 provide reliable connection points between the roller blind sheets 10. They can withstand the tension and pressure generated by the roller blind under frequent opening and closing, truck driving vibration, and external force impact.

[0102] By tightly connecting adjacent roller blind sheets 10, the problem of looseness, misalignment, etc. of the entire roller blind structure 100 during long-term use is reduced, the stable form is maintained, the normal operation of the roller blind is ensured, and the goods in the cargo box are protected from external interference.

[0103] In a possible implementation, one of the first connecting piece 31 and the second connecting piece 32 is a rotating shaft 311, and the other is a sleeve piece with a rotating groove 321; one of the two adjacent roller blind sheets 10 can rotate relative to the other.

[0104] By the rotating shaft 311 and the rotating groove 321, the difficulty of opening and closing the roller blind structure 100 can be reduced.

[0105] By the arrangement of the rotating shaft 311 and the rotating groove 321, the roller blind structure 100 can be switched between the retracted state and the expanded state.

[0106] In the retracted state of the roller blind, since the adjacent roller blind sheets 10 can rotate relative to each other, they can be more compactly stacked together. Compared with the fixed connection mode, this design reduces the space occupied by the roller blind when it is retracted, improves the space utilization rate, and thus increases the loading capacity of the cargo box.

[0107] In a possible implementation, referring to Figure 3 and Figure 4 The rotation angle of one of the two adjacent roller blind sheets 10 relative to the other is less than or equal to 50 degrees.

[0108] For example, the rotation angle of one of the two adjacent roller blind pieces 10 relative to the other can be one of 10 degrees, 20 degrees, 30 degrees, 40 degrees, and 50 degrees.

[0109] In a possible implementation, the rotating groove 321 is provided with a slot, and opposite ends of the slot are a first end portion 3211 and a second end portion 3212. The rotating shaft 311 can rotate between a first position and a second position. When the rotating shaft 311 is in the first position, the rotating shaft 311 is in contact with the first end portion 3211. When the rotating shaft 311 is in the second position, the rotating shaft 311 is in contact with the second end portion 3212. The included angle between the first position and the second position of the rotating shaft 311 is less than or equal to 50 degrees.

[0110] In the initial stage of rolling up the roller blind structure 100, the rotating shaft 311 is in the initial position, that is, the position close to the first end portion 3211. With the continuous action of the external force, the rotating shaft 311 gradually deviates from the initial position and moves to other areas in the slot. At this time, it drives the relative rotation between the adjacent roller blind pieces 10 to meet different use requirements, such as allowing more light to enter the box, or blocking part of the external airflow, or opening the box.

[0111] Due to the limitation of the second end portion 3212, the rotating shaft 311 cannot rotate freely without limit. Once the rotating shaft 311 reaches the second position, it will be in contact with the second end portion 3212. At this time, the included angle between the two adjacent roller blind pieces 10 is the maximum rotation angle. In this way, a series of problems caused by excessive rotation of the rotating shaft 311 can be avoided, such as damage to the sealing structure, loosening of the connection between the roller blind pieces 10, and the like.

[0112] The first end portion 3211 and the second end portion 3212 at the two ends of the slot provide clear and accurate physical boundaries for the rotation range of the rotating shaft 311. The rotation angle of the roller blind piece 10 can be accurately controlled within the preset range of less than or equal to 50 degrees, so as to realize accurate function adjustment.

[0113] In a possible implementation, referring to Figure 3 and Figure 4 The roller blind piece 10 comprises a first limiting portion and a second limiting portion, and the first limiting portion and the second limiting portion are located at the two ends of the main body portion 11 and are connected with the main body portion 11, respectively. The first limiting portion and the second limiting portion of the two adjacent roller blind pieces 10 cooperate to prevent the two adjacent roller blind pieces 10 from rotating to a second side, which is a side of the main body portion 11 away from the first bending portion 12 and the second bending portion 13.

[0114] If the adjacent roller blind pieces 10 rotate to the second side at will, the sealing member 20 will be pulled and twisted, and a gap will appear in the sealing member 20, which will damage the sealing effect. The limiting action of the first limiting portion and the second limiting portion avoids this situation.

[0115] The first limiting part and the second limiting part are located at both ends of the main body part 11 and cooperate with each other, effectively preventing the adjacent two roller shutter sheets 10 from rotating to the second side, and providing additional support for the roller shutter structure 100. The stability of the entire roller shutter structure 100 under complex working conditions can be improved, the risk of component damage caused by shaking and misalignment is reduced, and the service life of the roller shutter structure 100 is prolonged.

[0116] In a possible implementation, referring to Figure 3 and Figure 4 One of the first limiting part and the second limiting part is the overlapping groove 14 communicating with the second side, and the other is the overlapping part 15. The overlapping groove 14 includes an overlapping surface 141 facing the second side, and the overlapping part 15 overlaps the overlapping surface 141 to prevent the adjacent two roller shutter sheets 10 from rotating to the second side.

[0117] The overlapping groove 14 communicates with the second side and has a specific overlapping surface 141, which provides a precise docking platform for the overlapping part 15. When the overlapping part 15 overlaps the overlapping surface 141, they form a stable mechanical connection, which precisely limits the rotation trend of the adjacent roller shutter sheets 10 to the second side from a physical structure. In this way, the reliability of the limiting is enhanced, and the stable operation of the roller shutter structure 100 is ensured.

[0118] By overlapping the overlapping part 15 on the overlapping surface 141 to prevent the adjacent two roller shutter sheets 10 from rotating to the second side, the sealing element 20 can be attached along the overlapping part 15. At the same time of preventing rainwater and dust from seeping from the overlapping part, the sealing element 20 is more evenly stressed and is not easily damaged due to the shaking of the roller shutter sheet 10, further improving the sealing integrity and providing a more reliable protective barrier for the goods in the container. At the same time, the service life of the sealing element 20 is prolonged.

[0119] From the visual effect, the overlapping groove 14 and the overlapping part 15 closely cooperate, so that the appearance of the connecting part of the roller shutter sheet 10 is smooth and simple, without protruding blocking parts or gaps. In turn, the visual effect is improved.

[0120] In a possible implementation, the sealing element 20 is provided with a fourth recess 24. The fourth recess 24 is located on the side of the sealing element 20 away from the third recess 23.

[0121] As the adjacent roller shutter sheets 10 rotate, the sealing element 20 is extruded. At this time, the fourth recess 24 can be understood as a buffer groove, which provides a deformation space for the sealing element 20.

[0122] When the pressure comes, the material of the sealing piece 20 can be moderately recessed into the fourth recess 24, buffering the instantaneous impact force generated by the rotation of the roller shutter sheet 10, avoiding the rupture or permanent deformation of the sealing piece 20 due to the inability to withstand sudden compression. Improve the sealing performance of the sealing piece 20 under the long-term frequent rotation and extrusion working condition.

[0123] In one possible implementation, referring to Figure 3 and Figure 4 The fourth recess 24 is located between the first bending part 12 and the second bending part 13.

[0124] The first bending part 12 and the second bending part 13 are the main stress and connection parts in the structure of the roller shutter sheet 10. During the opening and closing rotation of the roller shutter sheet 10, the area between the first bending part 12 and the second bending part 13 bears a large stress. The fourth recess 24 is arranged between the first bending part 12 and the second bending part 13 to buffer the pressure from the high stress area. Thus, the sealing piece 20 and the surrounding roller shutter sheet 10 structure are protected from damage due to excessive local stress,

[0125] In one possible implementation, the first bending part 12 and the main body part 11 have a first included angle, and the sealing piece 20 and the inner wall surface of the first included angle form a first deformation gap 125.

[0126] The first deformation gap 125 provides a space for the deformation of the sealing piece 20. When the sealing piece 20 is extruded or stretched, the sealing piece 20 can be moderately deformed in the direction of the inner wall surface of the first included angle. The first deformation gap 125 absorbs stress, effectively preventing the sealing piece 20 from being broken or losing elasticity due to excessive instantaneous stress, and ensuring that it can maintain good sealing performance under complex working conditions.

[0127] In one possible implementation, referring to Figure 3 and Figure 4 The sealing piece 20 includes a first protruding part 25, and the first protruding part 25 is located in the first deformation gap 125.

[0128] When the sealing piece 20 is locally recessed or stretched under the action of vibration, extrusion, etc., the first protruding part 25 can immediately fill the new gap caused by deformation, improve the continuity of sealing, and effectively block the entry of dust and moisture.

[0129] The first protruding part 25 has a blocking effect on a small amount of infiltrated rainwater. The first protruding part 25 can block the path of rainwater flowing into the first side.

[0130] The second bending part 13 and the main body part 11 have a second included angle, and the sealing piece 20 and the inner wall surface of the second included angle form a second deformation gap 135.

[0131] The second deformation gap 135 provides a space for the deformation of the sealing member 20. When the sealing member 20 is pressed or stretched, the sealing member 20 can be moderately deformed towards the inner wall surface of the second included angle, and the stress can be absorbed by the second deformation gap 135, effectively preventing the sealing member 20 from being broken or losing elasticity due to excessive instantaneous stress, and ensuring that the sealing member 20 can maintain good sealing performance under complex working conditions.

[0132] In one possible implementation, referring to Figure 3 and Figure 4 The sealing member 20 includes a second protruding portion 26 located in the second deformation gap 135.

[0133] When the sealing member 20 is locally depressed or stretched under the action of vibration, pressure, etc., the second protruding portion 26 can immediately fill the new gap caused by deformation, improve the continuity of sealing, and effectively prevent dust and moisture from entering.

[0134] The second protruding portion 26 has a barrier effect on a small amount of infiltrated rainwater. The second protruding portion 26 can block the path of rainwater flowing into the first side.

[0135] In one possible implementation, referring to Figure 3 and Figure 4 The roller shutter sheet 10 includes a reinforcing rib 16 located between the first bending portion 12 and the second bending portion 13 and connected to the main body portion 11.

[0136] The reinforcing rib 16 can improve the strength of the roller shutter sheet 10. The first bending portion 12 and the second bending portion 13 are key connection and stress parts of the roller shutter sheet 10, and the reinforcing rib 16 can disperse and bear these stresses, conduct the pressure originally concentrated on the bending portion to the main body portion 11 and the entire structure of the roller shutter sheet 10, and reduce the risk of deformation of the roller shutter sheet 10.

[0137] In one possible implementation, referring to Figure 3 and Figure 4 The reinforcing rib 16 includes a third bending portion 161 connected to the main body portion 11, and the third bending portion 161 surrounds an air cavity 162.

[0138] The air cavity 162 provided in the middle of the reinforcing rib 16 can reduce the weight of the reinforcing rib 16.

[0139] In one possible implementation, the reinforcing rib 16 includes a reinforcing portion 163 located in the air cavity 162, and opposite ends of the reinforcing portion 163 are respectively connected to the third bending portion 161.

[0140] The reinforcing portion 163 provided can improve the strength of the reinforcing rib 16. The reinforcing portion 163 can disperse and bear the stress. The stress is evenly distributed, and the local deformation is reduced.

[0141] In one possible implementation, referring to Figure 3 、 Figure 4 and in conjunction with Figure 3 Figure 4 Figure 3 Figure 4 Figure 5 , a first seal will be formed between the first bending part 12 of the two adjacent roller blind pieces 10 and the second bending part 13 of the two adjacent roller blind pieces 10, forming a first tooth part. The reinforcing rib 16 is a second tooth part; the first tooth part and the second tooth part are arranged in a spaced manner, and the area between the first tooth part and the second tooth part forms a concave tooth part 41. The first tooth part, the second tooth part, and the concave tooth part 41 form a first convex-concave tooth part 40. The roller blind structure 100 further comprises a roller blind shaft 50; the roller blind shaft 50 is provided with a second convex-concave tooth part 51, which is in meshing connection with the first convex-concave tooth part 40.

[0142] Since the second convex-concave tooth part 51 provided on the roller blind shaft 50 is in meshing connection with the first convex-concave tooth part 40 on the roller blind piece 10, with the rotation of the roller blind shaft 50, the teeth of the second convex-concave tooth part 51 sequentially push the teeth of the first convex-concave tooth part 40.

[0143] Specifically: the convex teeth of the second convex-concave tooth part 51 will be embedded in the concave tooth part 41 of the first convex-concave tooth part 40, giving it a forward pushing force, so that the two adjacent roller blind pieces 10 start to move relatively under this meshing action.

[0144] With the continuous rotation of the roller blind shaft 50, the second convex-concave tooth part 51 repeatedly meshes with and disengages from the first convex-concave tooth part 40, pushing the roller blind pieces 10 to be rolled up one by one, and the relative positions between the adjacent roller blind pieces 10 are also adjusted in this process. The existence of the concave tooth part 41 provides a certain buffer space for the relative sliding between the tooth parts, so that the roller blind pieces 10 are more stable during the rising process, avoiding damage to the components due to rigid collision.

[0145] When closing the roller blind, the process is the opposite of opening. The roller blind shaft 50 is reversed, and the second convex-concave tooth part 51 meshes with the first convex-concave tooth part 40 in the opposite order, driving the roller blind pieces 10 to be lowered one by one. At this time, the first tooth part and the second tooth part also work cooperatively to ensure that the roller blind pieces 10 descend stably, the sealing element 20 is tightly attached, and the initial closed state is restored.
