[0032] Figure 5 Schematic diagram of the brake element of the roller blind according to an embodiment of the present invention, Figure 5 As shown, the roller blind includes: at least one set of side rails 51; a bottom rail 52 that cooperates with the at least one set of side rails 51 and moves on the at least one set of side rails 51; and at least one set of brake elements 53, wherein each set of brake elements 53 in the at least one set of brake elements is symmetrically arranged on the at least one set of side rails 51.

[0033] The following combination Figures 1 to 5 A detailed description of roller blinds is provided.

[0034] Preferably, each brake element in each set of brake elements has a first end fixedly mounted on one of the side rails; the other end of each brake element includes a movable end that connects the other end to the corresponding side rail and allows the brake element to move relative to the movable hole in a predetermined position. In this embodiment, the brake element blocks movement of the base rail through elastic deformation. For example, one end is provided with a waist-shaped elongated hole to slide within a screw, providing a relatively small force to facilitate elastic deformation of the brake element.

[0035] Preferably, the movable end can comprise a movable hole. In practical applications, the movable hole can comprise a waist-shaped hole or an elliptical hole. In this embodiment, the screw of the waist-shaped long hole adopts an anti-loosening design to prevent loosening of the screw due to vibration or external force during long-term use, thereby ensuring the reliability and safety of the brake element. The anti-loosening design effectively solves the problem of brake failure that can be caused by loosening of the screw, thereby ensuring long-term stable operation of the roller shutter.

[0036] In a preferred embodiment, the brake element has an elastic component for reducing the displacement speed of the bottom rail in the at least one group of side rails when the bottom rail is displaced through each group of brake elements.

[0037] Preferably, the elastic component has a progressive deformation to reduce the resistance of the bottom rail when passing through each group of brake elements. In this embodiment, the arc-shaped structure of the brake element (elastic component) can be designed as a progressive arc to optimize the stress condition when the bottom rail passes through, thereby ensuring smooth operation of the bottom rail. The progressive deformation design enhances the smoothness when the bottom rail passes through, reduces the occurrence of jamming, and improves the operation comfort of the roller shutter.

[0038] Preferably, the elastic component can comprise a plurality of elastic pieces. In this embodiment, the elastic deformation of the brake element is achieved by providing a plurality of elastic pieces, and each elastic piece can be connected by a spring to enhance the control ability of the running speed of the bottom rail, and the number and elastic coefficient of the elastic pieces can be adjusted according to requirements. By providing a plurality of elastic pieces and spring connections, the elastic adjustment ability of the brake element can be improved, so that the roller shutter can maintain the tightness of the fabric under different operating conditions, effectively preventing the occurrence of slackness.

[0039] Preferably, each brake element of each group of brake elements is integrally formed of metal. In this preferred embodiment, the brake element is an integral metal structure, which can improve durability and structural stability. In implementation, the surface can be treated for corrosion resistance to improve durability, and a buffer pad can be provided on the brake element to reduce noise and friction when the bottom rail passes through.

[0040] As a preferred embodiment, each side rail in the at least one group of side rails can adopt a plurality of ways. For example, it can be integrally formed; or it can be spliced by at least two components. In this preferred embodiment, the side rail (fixed seat) is spliced by two or more aluminum alloy components, which can be connected by buckles or bolts, and the side rail (fixed seat) can be provided with a guide groove to define the running track of the bottom rail, thereby ensuring stable and uniform contact between the bottom rail and the brake element during operation.

[0041] Preferably, the surface of the aluminum alloy component of the side rail (fixed seat) can be anodized to improve its corrosion resistance and surface hardness, thereby improving the weather resistance and service life of the roller shutter. The anodizing process effectively enhances the corrosion resistance of the aluminum alloy component, enabling the roller shutter to maintain stable performance in various harsh environments and extending the service life of the product.

[0042] It should be noted that the splicing method of the side rail in the present application can adopt seamless welding technology to reduce the damage of the component caused by stress concentration at the joint and improve the stability of the overall structure. The seamless welding technology effectively reduces the structural damage caused by stress concentration and improves the overall strength and service life of the roller shutter.

[0043] Preferably, the number of brake elements can be set according to the slack parameter of the fabric of the roller shutter.

[0044] Preferably, the elasticity of the elastic part of the brake element can be set according to the width and weight of the roller shutter. In the present embodiment, the elasticity can be increased or decreased according to the width and weight of the roller shutter to ensure that the roller shutter can maintain stable rolling effect in any size. By adjusting the elasticity of the brake element, the stability of the roller shutter in different sizes and weights is ensured, and the application range and reliability of the product are improved.

[0045] It should be noted that the installation position of the brake element can be adjusted according to actual use requirements to change the stress point of the bottom rail operation and meet the installation requirements in different scenes. The adjustability of the installation position enables the roller shutter to be optimized according to the actual scene, meets the individual needs of different users, and improves the flexibility and applicability of the product.

[0046] It should be noted that the surface of the brake element in the present application can be coated with wear-resistant material to increase the service life of the brake element, reduce the friction between the bottom rail and the brake element, and reduce wear and tear. The coating of wear-resistant material improves the service life of the brake element, reduces wear and tear, and ensures the long-term use effect of the roller shutter.

[0047] The present embodiment provides a roller shutter, which can include an intermittent brake (brake element) including a side rail (fixed seat), the side rail (fixed seat) is installed with multiple groups of intermittent brake elements, and the intermittent brake element has one end fixedly connected with the side rail (fixed seat). One end can slide freely, and the brake element can block the operation of the bottom rail through elastic deformation.

[0048] In the present embodiment, the intermittent brake spring can have an arc (gradual transition) structure.

[0049] Preferably, the intermittent brake spring piece is fixed at one end on the side rail (fixed seat) and has a waist-shaped long hole at the other end, which can slide in the screw. Figure 4 The waist-shaped long hole (see 431 in the drawings) can require less force in a single direction and provide relatively easier elastic deformation.

[0050] In practice, the side rail (fixed seat) is composed of two or more aluminum alloy components.

[0051] Preferably, the intermittent brake spring piece is a one-piece metal structure.

[0052] In the above embodiments and preferred embodiments, each group of brake elements is asymmetrically arranged on the side rail, which can be more flexible in setting the brake elements.

[0053] It should be noted that the side rail in the above embodiments can be replaced by the columns on both sides of the curtain wall (that is, the original foundation material can be replaced).

[0054] It should be noted that the side rail in the above embodiments and preferred embodiments can be segmented, such as the brake fixed seat.

[0055] Through the above embodiments and preferred embodiments, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 When the flat-packed roller blind is rolled up, the bottom rail cannot use gravity to affect the running speed of the bottom rail end fabric, causing the fabric to run at both ends. Since the brake elements (intermittent brakes) are arranged on both sides of the side rail, when the bottom rail runs to the brake elements (intermittent brakes), it will be blocked by the brake elements (intermittent brakes), reducing the movement speed. At the same time, the fabric at the tube will continue to wind up. When the fabric at this stage is wound up, the power source will increase a pulling force on the bottom rail through the fabric. At this time, the bottom rail squeezes the intermittent brake spring piece, and the intermittent brake spring piece begins to elastically deform, allowing the bottom rail to pass through the spring piece. The fabric drives the bottom rail to continue to run to the next spring piece, waiting for the next round of rolling operation. Week after week, it achieves the flat and tight fabric roll when the roller blind is rolled up in flat or inverted state, which not only improves the appearance of the product, but also improves the wind resistance of the roller blind.

[0056] The present application provides ideal elastic deformation by setting brake elements (intermittent brake elements), which can make the bottom rail lifting sequence later than the tube lifting sequence, achieving the purpose of fabric curling flat.

[0057] In summary, through the above-mentioned embodiments and preferred embodiments, a roller shutter is provided, by installing brake elements (intermittent brake springs) on the side rails (fixed seats), the tension when the roller shutter is rolled up is not greater than when the roller shutter is unrolled (the fabric cannot be too tight). In order to prevent the fabric from being too loose, the brake elements (intermittent brakes) are provided, so that the fabric can be loose and tight at times, so as to achieve the rolling rule of the roller shutter, and the appearance and practicability are improved, so as to improve the appearance and practicability of the product to a certain extent.
