[0028] First embodiment

[0029] The present invention provides a single-motor driven multi-angle and T-type transmission rolling curtain, including a driving component 101, a first transmission shaft 102, a right-angle transmission 103, a second transmission shaft 104, a transmission gear set 105 and an angle curtain transmission component 106, the first transmission shaft 102 is connected to the driving component 101, the driving component 101 drives the first transmission shaft 102 to rotate, the right-angle transmission 103 is connected to the first transmission shaft 102, one end of the transmission gear set 105 is connected to the right-angle transmission 103, the second transmission shaft 104 is connected to the other end of the transmission gear set 105, rolling curtains are arranged on the first transmission shaft 102 and the second transmission shaft 104, the angle curtain transmission component 106 is connected to the right-angle transmission 103, and an angle curtain is arranged on the angle curtain transmission component 106, and the angle curtain is arranged between the rolling curtains on the first transmission shaft 102 and the second transmission shaft 104.

[0030] In this embodiment, the driving assembly 101 serves as the power source of the entire system. It is directly connected to the first transmission shaft 102, and the first transmission shaft 102 is driven to rotate by the rotation of the motor. The first transmission shaft 102 is not only connected to the driving assembly 101, but also connected to one end of the transmission gear set 105 through the right-angle transmission 103. Specifically, two meshing bevel gears can be used to achieve effective transmission of force from the first transmission shaft 102 to the second transmission shaft 104 in the vertical direction. Rolling curtains are set on both the first transmission shaft 102 and the second transmission shaft 104, so that the user can control the opening and closing of rolling curtains at different positions at the same time through the drive of a single motor, which greatly improves the convenience and efficiency of use. In addition, in order to further improve the sealing performance and block the gap at the joint of two mutually perpendicular rolling curtains, the present invention also sets an angle curtain transmission assembly 106 and connects it to the right-angle transmission 103. The right-angle transmission device 103 can also drive the angle curtain transmission assembly 106 to rotate synchronously when rotating. The angle curtain transmission assembly 106 is equipped with an angle curtain, which is arranged between the rolling curtains controlled by the first transmission shaft 102 and the second transmission shaft 104, so that the gap between the two rolling curtains can be closed to form a better sealing effect, providing a more flexible and changeable space management method. Therefore, a single motor can be used to drive multiple rolling shutter doors at the corner to move synchronously. Compared with the multi-motor drive method, the synchronization and reliability are higher, so that the use effect is better.

[0031] The driving assembly 101 includes a driving support plate 107, a driving motor 108 and a reduction gear set 109. The driving support plate 107 is fixed to the wall. The reduction gear set 109 is rotatably set on the driving support plate 107. The driving motor 108 is connected to the input end of the reduction gear set 109, and the first transmission shaft 102 is connected to the output end of the reduction gear set 109.

[0032] The driving support plate 107 provides a stable installation platform for the driving motor 108 and the reduction gear set 109. In order to ensure the stability of the driving assembly 101 throughout the entire service life, the driving support plate 107 is firmly fixed to the wall. The driving motor 108 is directly connected to the input end of the reduction gear set 109, and provides the necessary driving force for the entire system by converting electrical energy into mechanical energy. Selecting a suitable driving motor 108 is essential to ensure that the roller blind can run smoothly and efficiently. The reduction gear set 109 is rotatably arranged on the driving support plate 107, which not only realizes the effective connection with the driving motor 108, but also ensures the precise docking with the first transmission shaft 102. The main function of the reduction gear set 109 is to reduce the output speed of the driving motor 108 and increase the output torque at the same time, so as to drive the first transmission shaft 102 more effectively. This design can not only reduce the load of the motor and extend its service life, but also make the opening and closing process of the roller blind smoother and more fluent, improving the user experience.

[0033] The right-angle transmission 103 includes a first installation box 110, a first bevel gear 111 and a second bevel gear 112. The first bevel gear 111 and the second bevel gear 112 are meshed and arranged in the first installation box 110. The first transmission shaft 102 is connected to the first bevel gear 111, and the transmission gear set 105 is connected to the second bevel gear 112.

[0034] The first mounting box 110 provides necessary protection and support as the housing of the entire right-angle transmission 103. It not only ensures the safety and stability of the internal precision components (such as bevel gears), but also provides a compact and orderly working environment for these components.

[0035] The first bevel gear 111 and the second bevel gear 112 are key components for achieving right-angle transmission. The two bevel gears are precisely manufactured and meshed with each other in the first mounting box 110, thereby achieving force transmission from one direction to another perpendicular direction. The first bevel gear 111 is directly connected to the first transmission shaft 102. When the driving assembly 101 drives the first transmission shaft 102 to rotate, the first bevel gear 111 also rotates, so that the right-angle transmission can be achieved more stably. The meshing angle of the two bevel gears can be set as needed and is not limited to 90° as shown in the accompanying drawings.

[0036] The corner curtain transmission assembly 106 includes a first transmission member 113, a first universal joint 114, a second transmission member 115 and a third transmission shaft 116. The first transmission member 113 is connected to the shaft of the first bevel gear 111. The universal joint connects the first transmission member 113 and the second transmission member 115. The second transmission member 115 is connected to the third transmission shaft 116. The third transmission shaft 116 is provided with a corner curtain.

[0037] The first transmission member 113 is the starting point of the entire angle curtain transmission assembly 106, and it is directly connected to the shaft of the first bevel gear 111 in the right-angle transmission 103. This means that when the driving assembly 101 drives the first bevel gear 111 to rotate, the first transmission member 113 will also start to move.

[0038] In order to overcome the power transmission problem caused by the angle change, the first universal joint 114 is introduced into the corner curtain transmission assembly 106. The universal joint is a mechanical joint that allows the two ends of the connection to rotate relative to each other within a certain angle range. Its existence ensures that the power can be smoothly transferred from the first transmission member 113 to the second transmission member 115 even in a complex installation environment. The first universal joint 114 connects the first transmission member 113 and the second transmission member 115. This connection method not only solves the problem of force transmission between different axes, but also improves the flexibility and adaptability of the system.

[0039] Then the power is further transmitted forward through the second transmission member 115. One end of the second transmission member 115 is connected to the first universal joint 114, and the other end is connected to the third transmission shaft 116. This design ensures that the power can be smoothly transferred from the first transmission member 113 to the third transmission shaft 116 via the universal joint. The corner curtain is arranged on the third transmission shaft, so that the corner curtain can be driven to move synchronously.

[0040] The first transmission member 113 includes a first support plate 117, a first gear 118, an intermediate gear 119 and a second gear 120. The first support plate 117 is sleeved on the shaft of the first bevel gear 111. The first gear 118 is fixedly connected to the first bevel gear 111. The intermediate gear 119 is rotatably set on the first support plate 117 and meshes with the first gear 118. The second gear 120 is rotatably set on the first support plate 117 and meshes with the intermediate gear 119. The first universal joint 114 is connected to the second gear 120.

[0041] The first support plate 117 is the basic frame of the entire first transmission member 113, and is sleeved on the shaft of the first bevel gear 111. This design not only provides a stable installation platform for other components, but also ensures the stability and reliability of the overall structure of the first transmission member 113.

[0042] The first gear 118 is a key component that is directly fixedly connected to the first bevel gear 111. When the driving assembly 101 drives the first bevel gear 111 to rotate, the first gear 118 will also rotate synchronously.

[0043] The second gear 120 is also rotatably disposed on the first support plate 117 and meshes with the intermediate gear 119. This arrangement allows the second gear 120 to receive power from the intermediate gear 119 and transmit it further. This allows the second gear 120 and the first gear 118 to rotate in the same direction, and finally, the first universal joint 114 is connected to the second gear 120. The universal joint is a special mechanical joint that allows both ends to rotate relative to each other within a certain angle range, which allows power to be smoothly transmitted from the second gear 120 to the subsequent transmission components (such as the second transmission member 115) even if there is an angle difference between the two.

[0044] The structure of the second transmission member 115 is the same as that of the first transmission member 113. Thus, the second transmission member 115 can drive the third transmission shaft to rotate in the same direction as the first bevel gear 111, thereby driving the corner curtain and other rolling curtains to fall or rise synchronously, so as to achieve better use effect.

[0045] The single-motor flexible driven multi-application scenario special-shaped roller blind structure also includes a guide track 137, and the guide track 137 is arranged on one side of the roller blind to guide the roller blind to form an arc arrangement from a polygonal arrangement.

[0046] The guide track 137 is a crucial component of the roller blind system. It is arranged on one side of the roller blind and is mainly used to guide the roller blind to change from the original rigid polygonal arrangement to a more smooth and natural arc arrangement. In this way, not only the overall aesthetics of the roller blind can be improved, but also the best shielding effect can be achieved in spaces of different shapes.

[0047] Second embodiment

[0048] The present invention provides a single-motor driven multi-angle and T-type transmission rolling curtain, including a driving component 101, a first transmission shaft 102, a right-angle transmission 103, a second transmission shaft 104, a transmission gear set 105 and an angle curtain transmission component 106, the first transmission shaft 102 is connected to the driving component 101, the driving component 101 drives the first transmission shaft 102 to rotate, the right-angle transmission 103 is connected to the first transmission shaft 102, one end of the transmission gear set 105 is connected to the right-angle transmission 103, the second transmission shaft 104 is connected to the other end of the transmission gear set 105, rolling curtains are arranged on the first transmission shaft 102 and the second transmission shaft 104, the angle curtain transmission component 106 is connected to the right-angle transmission 103, and an angle curtain is arranged on the angle curtain transmission component 106, and the angle curtain is arranged between the rolling curtains on the first transmission shaft 102 and the second transmission shaft 104.

[0049] Compared with the first embodiment, the difference is that, in this embodiment, the length of the second transmission shaft 104 is greater than the length of the second transmission shaft 104 in the first embodiment, so that the first transmission shaft 102 and the second transmission shaft 104 form a T-shaped structure, and the roller blinds on the first transmission shaft 102 and the second transmission shaft 104 also form a T-shaped structure, so that two corner curtains are required to form a corresponding closed structure.

[0050] Specifically, the right-angle transmission 103 includes a second installation box 121, a third bevel gear 122 and a fourth bevel gear 123, a fifth bevel gear 127 and a fourth transmission shaft 138. The third bevel gear 122 and the fourth bevel gear 123 are meshed and arranged in the second installation box 121, the first transmission shaft 102 is connected to the third bevel gear 122, the transmission gear set 105 is connected to the fourth bevel gear 123, the fifth bevel gear 127 is connected to the third bevel gear 122, and the fourth transmission shaft 138 is fixed on the fifth bevel gear 127.

[0051] The second installation box 121 serves as the housing of the right-angle transmission 103, providing the necessary protection and support structure. The third bevel gear 122 and the fourth bevel gear 123 mesh with each other and are arranged in the second installation box 121. Their main function is to realize the power transmission from the first transmission shaft 102 to the transmission gear set 105 and change the direction of the force. Specifically, the first transmission shaft 102 is directly connected to the third bevel gear 122. When the driving assembly 101 drives the first transmission shaft 102 to rotate, the third bevel gear 122 rotates accordingly. Due to the close meshing of the third bevel gear 122 and the fourth bevel gear 123, this design enables power to be smoothly converted from one direction to another vertical direction, thereby driving the transmission gear set 105 connected to the fourth bevel gear 123. In order to further expand the system function, the right-angle transmission 103 also includes a fifth bevel gear 127. The fifth bevel gear 127 is connected to the third bevel gear 122, which means that it can receive power from the third bevel gear 122 to drive the fourth transmission shaft 138 to rotate. This design increases the flexibility of the system, allowing more power distribution paths and control options. The fourth transmission shaft 138 is provided with a roller blind as required to better form a shielding structure.

[0052] The corner curtain transmission assembly 106 includes a second support plate 124, a third gear 125, a fourth gear 128, a second universal joint 126, a first corner curtain shaft 130, a gear box 131 and a second corner curtain shaft 132. The second support plate 124 is arranged on one side of the second mounting box 121. The third gear 125 is connected to the fourth transmission shaft 138. The fourth gear 128 is rotatably arranged on the second support plate 124 and meshes with the third gear 125. The second universal joint 126 is connected to the fourth gear 128 and to the first corner curtain shaft 130. The gear box 131 is connected to the first corner curtain shaft 130 and the second corner curtain shaft 132. Corner curtains are arranged on the first corner curtain shaft 130 and the second corner curtain shaft 132.

[0053] The second support plate 124 is the basic frame of the entire angle curtain transmission assembly 106 and is arranged on one side of the second installation box 121. The third gear 125 is directly connected to the third transmission shaft 116. When the power is transmitted to the third transmission shaft 116 through the fifth bevel gear 127 and the direction-changing gear set in the right-angle transmission 103, the third gear 125 rotates accordingly. At this time, the rotation direction of the third gear 125 is opposite to that of the first transmission shaft 102, and then it is transmitted through the fourth gear 128, so that the second universal joint 126 connected to the fourth gear 128 has the same rotation direction as the first transmission shaft 102. The first angle curtain shaft 130 connected to the second universal joint 126 can rotate synchronously with the first transmission shaft 102, and then the second angle curtain shaft 132 rotates synchronously with the first angle curtain shaft 130 through the gear box 131, wherein the gear box 131 is also composed of two bevel gears meshing inside. Thus, two T-shaped rolling curtains can be driven by a single motor, and the angle curtains located on both sides of the T-shaped can be lowered or raised synchronously, so that the user experience is better.

[0054] Third embodiment

[0055] On the basis of the second embodiment, the single-motor driven corner roller shutter structure of the present invention also includes an extension structure, which includes a first extension transmission member 133, a second extension transmission member 134, an intermediate shaft 135 and an extension shaft 136, the first extension transmission member 133 is connected to the second transmission shaft, the intermediate shaft 135 is connected to the first extension transmission member 133, the second extension transmission member 134 is connected to the intermediate shaft 135 and the extension shaft 136, and the roller shutter arranged on the intermediate shaft 135 is used to close the gap formed by the roller shutters on the second transmission shaft and the extension shaft 136.

[0056] The first extension transmission member 133 is the first important component of this extension mechanism, which is directly connected to the second transmission shaft 104. Through this direct connection, the first extension transmission member 133 can obtain rotational power from the second transmission shaft 104, and the intermediate shaft 135 is connected to the first extension transmission member 133, receiving and continuing to transmit power from the first extension transmission member 133. In addition, a specially designed roller blind is provided on the intermediate shaft 135, the purpose of which is to close any gap that may be formed between the roller blind on the second transmission shaft 104 and the extension shaft 136, to ensure the integrity and aesthetics of the shielding effect. This design not only improves the sealing performance of the system, but also increases the stability and durability of the overall structure.

[0057] The second extension transmission member 134 is connected to the intermediate shaft 135 and the extension shaft 136. In this way, the second extension transmission member 134 can smoothly transmit the power received from the intermediate shaft 135 to the extension shaft 136, ensuring that the extension part can also run smoothly. Such a design not only enhances the adaptability of the system, enabling it to cope with a wider range of layout requirements, but also improves the flexibility and convenience of operation.

[0058] The extension shaft 136 is the last link of the extension structure. After receiving the power from the second extension transmission member 134, it starts to rotate and drives the roller blind on it to work. The existence of the extension shaft 136 greatly expands the coverage of the roller blind system, allowing the system to provide an effective shading solution in a larger space.

[0059] Fourth embodiment

[0060] The present invention also provides an application of a single-motor flexibly driven special-shaped rolling shutter structure with multiple application scenarios. The single-motor flexibly driven special-shaped rolling shutter structure with multiple application scenarios is applied to fireproof rolling shutter doors and flexible smoke barrier vertical walls.

[0061] Applying the single-motor flexible drive multi-application scenario special-shaped roller shutter structure to fireproof roller shutter doors can greatly improve the functionality and reliability of fireproof roller shutter doors. Traditional fireproof roller shutter doors often require a large installation space and a complex drive system to operate, but the flexible drive structure of the present invention can effectively overcome these limitations. Utilizing a single motor drive and an optimized transmission design, the system can not only achieve fast and smooth operation in a limited space, but also ensure that the fireproof roller shutter door is quickly closed in an emergency, effectively preventing the spread of fire.

[0062] In addition to fireproof rolling shutter doors, this structure is also suitable for application scenarios of flexible smoke barriers. The main function of the flexible smoke barrier is to prevent the spread of smoke during a fire and ensure the safety and smooth flow of evacuation passages. Using the single-motor flexible drive system provided by the present invention, the flexible smoke barrier can be made lighter and easier to operate, while maintaining excellent sealing performance and effectively preventing smoke penetration. Especially in large public facilities such as shopping malls, theaters, office buildings, factories and other places, due to the high flexibility of the structure, flexible smoke barriers, fireproof rolling shutter doors or other types of curtains can be quickly deployed according to different room layouts and exit locations.

[0063] In addition, in a home environment, this roller blind structure can be used to achieve automated control of curtains. It is not limited to traditional straight-edge designs, but can also adapt to various window shapes, such as round, arched, etc., providing more design possibilities and practicality for the home environment.

[0064] In industrial production lines, in order to ensure the safety of workers, this type of roller shutter can also be used as a safety shield around the machine to prevent accidental contact with dangerous parts. By applying this innovative single-motor flexible drive multi-application scenario special-shaped roller shutter structure, not only can the performance of various protective devices be improved, but it can also be flexibly adjusted according to specific needs to meet specific requirements in different scenarios. This not only reflects the convenience brought by technological progress, but also demonstrates its huge potential in ensuring safety.
