[0002] Roller shutters are fire safety devices designed to automatically descend when a fire occurs to stop the spread of flames and smoke. They are usually made of fire-resistant materials and can maintain structural integrity and flame retardant properties for a certain period of time, buying valuable time for evacuation and reducing property losses. Roller shutters can be connected to the building's fire alarm system for automatic response, or they can be manually operated to provide additional security in an emergency. This type of door is widely used in entrances and exits or separated areas in public places such as shopping malls, warehouses, and parking lots, and is an indispensable fire isolation facility in modern buildings.

[0003] Today’s building interiors are becoming increasingly complex, especially with the diversification of design concepts and technological advances, polygonal building designs are becoming more and more popular. Such buildings often contain multiple corners, irregularly shaped spaces, and complex floor plans. Traditional installation methods often have difficulty adapting to this diversity and complexity. For roller shutter structures, traditional installation methods are mainly aimed at relatively regular rectangular or square space designs.

[0025] First embodiment

[0026] See also Figure 1 to Figure 6 The present invention provides a single-motor driven linear and arc-shaped transmission rolling curtain structure, including a driving component 101, a first transmission shaft 102, an angle universal joint 103, a second transmission shaft 104, an angle curtain transmission structure 105 and an angle curtain assembly 106, wherein the driving component 101 is used to drive the first transmission shaft 102 to rotate, and the first transmission shaft 102 and the second transmission shaft 104 are provided with a rolling curtain structure, the second transmission shaft 104 is connected to the first transmission shaft 102 through the angle universal joint 103, the angle curtain transmission structure 105 is connected to the first transmission shaft 102, and the angle curtain assembly 106 is connected to the angle curtain transmission structure 105, and is used to close the gap formed between the two rolling curtain structures on the first transmission shaft 102 and the second transmission shaft 104.

[0027] In this embodiment, the drive assembly 101 provides rotational power to the first transmission shaft 102 so that the entire system can operate normally. The first transmission shaft 102 is directly connected to the drive assembly 101, and a rolling shutter structure is arranged thereon to achieve a shielding function. In order to expand the coverage of the system and adapt to different spatial layout requirements, the second transmission shaft 104 is connected to the first transmission shaft 102 through a corner universal joint 103. The design of this universal joint allows a certain angle change between the two transmission shafts, so that the rolling shutter can flexibly adapt to various complex installation environments.

[0028] Similarly, a rolling curtain structure is also provided on the second transmission shaft 104, so that the shielding area can be expanded or the shielding angle and position can be adjusted. In addition, an angle curtain transmission structure 105 is also provided, which is directly connected to the first transmission shaft 102, in order to drive the angle curtain assembly 106. The function of the angle curtain assembly 106 is to close any gap that may be formed between the rolling curtain structure on the first transmission shaft 102 and the second transmission shaft 104, thereby ensuring the integrity of the shielding effect and improving the sealing performance of the system.

[0029] This single-motor driven linear and arc-shaped transmission roller shutter structure not only effectively solves the problem that traditional roller shutter systems are difficult to flexibly deploy in complex environments, but also has higher stability than multi-motor drive. It also achieves effective use and beautification of space and is suitable for a variety of occasions, such as homes, offices or other public spaces.

[0030] The corner curtain transmission structure 105 includes a first transmission member, a first universal joint 108 and a second transmission member, the first transmission member is connected to the first transmission shaft 102, the second transmission member is connected to the first transmission member through the first universal joint 108, and the corner curtain assembly 106 is connected to the second transmission member.

[0031] The first transmission member is directly connected to the first transmission shaft 102. Through this direct mechanical connection, the first transmission member can obtain energy from the rotational power provided by the drive assembly 101 and transmit it to subsequent components. In order to cope with possible angular offsets or spatial layout limitations, the corner curtain transmission structure 105 introduces a first universal joint 108. The first universal joint 108 is located between the first transmission member and the second transmission member, which allows a certain angular deviation between the two transmission members, so that the entire system can maintain its functionality and flexibility even in the face of complex installation environments or irregular spatial layouts.

[0032] The second transmission member is connected to the first transmission member through the first universal joint 108, and plays the role of transmitting power from the first transmission member to the corner curtain assembly 106. Due to the existence of the first universal joint 108, the second transmission member can adjust its position and angle according to actual needs to ensure the best force transmission effect and operational convenience. Finally, the corner curtain assembly 106 is connected to the second transmission member, so that when the second transmission member is acted upon by power from the first transmission member and transmitted through the first universal joint 108, it can drive the corner curtain assembly 106 to move accordingly, thereby effectively closing the gap between the rolling curtain structures on the first transmission shaft 102 and the second transmission shaft 104.

[0033] The first transmission member includes a first supporting plate 110, a first driving gear 111, a first intermediate gear 112 and a first driven gear 113. The first driving gear 111 is rotatably arranged on the first supporting plate 110 and connected to the first transmission shaft 102. The first intermediate gear 112 is meshed with the first driving gear 111. The first driven gear 113 is meshed with the first intermediate gear 112. One end of the first universal joint 108 is connected to the first driven gear 113. The second transmission member includes a second supporting plate 129, a second driving gear 130, a second intermediate gear 131, a second driven gear 132 and an intermediate shaft 133. The second driving gear 130 is rotatably arranged on the second supporting plate 129 and connected to the other end of the first universal joint 108. The second intermediate gear 131 is meshed with the second driving gear 130. The second driven gear 132 is meshed with the second intermediate gear 131. The intermediate shaft 133 is connected to the second driven gear 132. The corner curtain assembly 106 is connected to the intermediate shaft 133.

[0034] The first support plate 110 provides a solid installation foundation for the entire assembly, ensuring that all components can operate stably. The first driving gear 111 is rotatably disposed on the first support plate 110 and is directly connected to the first transmission shaft 102, so that when the first transmission shaft 102 rotates, the first driving gear 111 will also rotate. The first driven gear 113 is meshed with the first intermediate gear 112, further receiving and transmitting power from the first driving gear 111. Finally, one end of the first universal joint 108 is connected to the first driven gear 113, ready to transmit power to the second transmission member, and the presence of the first universal joint 108 allows a certain angle of offset between the two transmission members, increasing the flexibility and adaptability of the system.

[0035] The second transmission member has the same structure as the first transmission member, so as to drive the corner curtain assembly 106 on the intermediate shaft 133 to rotate synchronously with the first transmission shaft 102 in the same direction, so as to control the synchronous movement of multiple rolling curtains at the same time.

[0036] The driving assembly 101 includes a driving support plate 114, a driving motor 115 and a reduction gear set 116. The driving support plate 114 is fixed to the wall. The reduction gear set 116 is rotatably set on the driving support plate 114. The driving motor 115 is connected to the input end of the reduction gear set 116, and the first transmission shaft 102 is connected to the output end of the reduction gear set 116.

[0037] The driving support plate 114 is the basic supporting structure of the driving assembly 101. It is firmly fixed to the wall to ensure that the entire driving system has a stable and reliable installation platform. The driving motor 115 is the power source of the driving assembly 101, providing the necessary mechanical power to drive the operation of the entire rolling shutter system. The driving motor 115 is connected to the input end of the reduction gear set 116. Through this direct mechanical connection, the driving motor 115 can convert electrical energy into mechanical kinetic energy and transmit it to the reduction gear set 116. Selecting a suitable driving motor 115 is crucial to ensuring the operating efficiency and response speed of the system. At the same time, factors such as energy consumption and noise need to be considered to meet the needs of different application scenarios. The reduction gear set 116 is rotatably arranged on the driving support plate 114, located between the driving motor 115 and the first transmission shaft 102, and plays a key role in reducing speed and increasing torque. The design purpose of the reduction gear set 116 is to reduce the high-speed rotation output by the driving motor 115 to an ideal speed suitable for rolling shutter operation, while increasing torque, so as to drive the first transmission shaft 102 more effectively. This design can not only improve the operating accuracy and stability of the system, but also effectively extend the service life of the system.

[0038] The single-motor driven linear and arc-shaped transmission roller shutter structure also includes an extension structure, which includes a first extension transmission member 118, a second extension transmission member 119, a transition shaft 120 and an extension shaft 121. The first extension transmission member 118 is connected to the second transmission shaft, the transition shaft 120 is connected to the first extension transmission member 118, the second extension transmission member 119 is connected to the transition shaft 120 and the extension shaft 121, and the roller shutter arranged on the transition shaft 120 is used to close the gap formed by the roller shutters on the second transmission shaft and the extension shaft 121.

[0039] The first extension transmission member 118 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 118 can obtain rotational power from the second transmission shaft 104, and the transition shaft 120 is connected to the first extension transmission member 118, receiving and continuing to transmit power from the first extension transmission member 118. In addition, a specially designed roller blind is provided on the transition shaft 120, 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 121, 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.

[0040] The second extension transmission member 119 is connected to the transition shaft 120 and the extension shaft 121. In this way, the second extension transmission member 119 can smoothly transmit the power received from the transition shaft 120 to the extension shaft 121, 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.

[0041] The extension shaft 121 is the last link of the extension structure. After receiving the power from the second extension transmission member 119, it starts to rotate and drives the roller blind on it to work. The existence of the extension shaft 121 greatly expands the coverage of the roller blind system, allowing the system to provide an effective shading solution in a larger space.

[0042] The first extended transmission member 118 includes a first extended support plate 122, a first gear set 123, an extended transmission shaft 124, a second gear set 125 and a second extended support plate 126, the first extended support plate 122 supports the first gear set 123, the first gear set 123 is connected to the second transmission shaft 104 and the extended transmission shaft 124, the second gear set 125 is connected to the extended transmission shaft 124 and the transition shaft 120, and the second extended support plate 126 is used to support the second gear set 125.

[0043] The first extension support plate 122 is a basic support structure. It provides a solid mounting platform for the first gear set 123, ensuring that the gear set can work in a stable state. The design of the first extension support plate 122 takes into account the overall stability of the system, and can effectively resist the influence of external factors such as vibration or temperature changes, ensuring the reliability of long-term use.

[0044] The first gear set 123 is fixed on the first extended support plate 122 and connected to the second transmission shaft 104 and the extended transmission shaft 124. The first gear set 123 is designed to achieve power transmission from the second transmission shaft 104 to the extended transmission shaft 124. In order to allow the extended transmission shaft 124 to rotate synchronously with the second transmission shaft 104 in the same direction, the number of gears in the first gear set 123 is 3 or more odd numbers.

[0045] The extended transmission shaft 124 starts to rotate after receiving the power from the first gear set 123 , and continues to transmit the power to the second gear set 125 .

[0046] The second gear set 125 receives power from the extended transmission shaft 124 and further transmits it to the transition shaft 120. In order to make the transition shaft 120 rotate synchronously with the second transmission shaft 104 in the same direction, the number of gears in the second gear set 125 is 3 or more odd numbers.

[0047] This design not only helps maintain consistency and stability in power transmission, but also allows for proper adjustment and optimization of power, ensuring that each link gets the power support it requires.

[0048] The second extended support plate 126 is used to support the second gear set 125 and provides a stable installation foundation. Similar to the first extended support plate 122, the second extended support plate 126 also needs to have sufficient strength and stability.

[0049] The first extended support plate 122 and the second extended support plate 126 are provided with arc grooves 127 , and the arc grooves 127 are used to reduce the gaps between the transition shaft 120 and the second transmission shaft 104 and the extended transmission shaft 124 .

[0050] The arc groove 127 is provided on the first extension support plate 122 and the second extension support plate 126. This design takes into account the possible slight displacement between the transition shaft 120 and the second transmission shaft 104 and the extension transmission shaft 124, and aims to reduce the gap between these components through an optimized mechanical design.

[0051] The single-motor driven linear and arc-shaped transmission rolling curtain structure further includes a guide track 128, which is arranged on one side of the rolling curtain and is used to guide the rolling curtain to form an arc-shaped arrangement from a polygonal arrangement.

[0052] The guide track 128 is a crucial component of the roller blind system. It is set on one side of the roller blind and is mainly used to guide the roller blind to change from the original rigid polygonal layout to a more smooth and natural arc layout. In this way, not only can the overall aesthetics of the roller blind be improved, but also it can ensure that it can achieve the best shielding effect in spaces of different shapes. The design of the guide track 128 fully considers the user's pursuit of space utilization efficiency and visual beauty, so that even complex or irregular space layouts can be handled elegantly.

[0053] Second embodiment

[0054] The present invention also provides an application of a single-motor driven linear and arc-shaped transmission rolling shutter structure, which is applied to fireproof rolling shutter doors and flexible smoke barrier vertical walls.

[0055] The application of the single motor driven linear and arc transmission rolling shutter structure in fireproof rolling shutter doors can significantly improve the functionality and reliability of fireproof rolling shutter doors. Traditional fireproof rolling shutter doors usually require a large installation space and a complex drive system, while the flexible drive structure of the present invention can effectively overcome these limitations. By using a single motor drive and an optimized transmission design, the system can achieve fast and smooth operation in a limited space, ensuring that the fireproof rolling shutter door can be quickly closed in an emergency to prevent the spread of fire.

[0056] In addition to fireproof rolling shutter doors, this structure is also suitable for application scenarios of flexible smoke barriers. Flexible smoke barriers are mainly used to prevent the spread of smoke during fires and to protect the safety and smooth flow of evacuation passages. The single-motor flexible drive system provided by the present invention can make the flexible smoke barriers lighter and easier to operate, while maintaining a high degree of sealing and effectively blocking the penetration of smoke. Especially in large public facilities such as shopping malls, theaters, office buildings, factories and the like, the high flexibility of this structure can be used to quickly deploy flexible smoke barriers, fireproof rolling shutter doors or other curtains according to different room layouts and exit locations.

[0057] In addition, in a home environment, it can be used to realize automatic control of curtains. It is not limited to the traditional straight-edge design, but can also adapt to various window shapes, such as round, arched, etc.

[0058] In industrial production lines, to ensure worker safety, this roller shutter can be used as a safety guard around the machine to prevent accidental contact with dangerous parts.

[0059] What is disclosed above is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
