[0040] The following is combined with Figure 1-17 , the specific implementation methods of the present invention are further described in detail to make the technical solution of the present invention easier to understand and grasp.

[0041] In this embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right side", "end", "front", "back", "middle", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0042] In addition, in this specific embodiment, if the connection or fixing method between components is not specifically described, the connection or fixing method can be through bolt fixing or pin fixing, or pin shaft connection and the like commonly used in the prior art, and therefore, it is not described in detail in this embodiment.

[0043] like Figure 1-4 As shown, a curtain mechanism comprises: a top rail 1, at least one wire reel 2 and a first rotating member 3, a first opening 11 is provided at the lower end of the top rail 1, and a second opening 16 is provided at each end of the top rail 1. Compared with the existing curtain mechanism, since the bottom of the existing curtain mechanism is closed, it is necessary to punch holes in the wire reel 2 to fix it, which makes the strength of the curtain mechanism lower, and undoubtedly increases the labor intensity and assembly difficulty, which is time-consuming and labor-intensive, and also makes the top rail 1 as a whole unsightly. In the present application, by providing the first opening 11 at the bottom of the top rail 1 and opening the second openings 16 at both ends of the top rail 1, there is no need to punch holes in the top rail 1 to fix the wire reel 2 and the motor 8, and they only need to be put in from the second opening 16 of the top rail 1, and assembly can be achieved without punching holes, thereby reducing the difficulty of assembly and saving time, and the end cover 7 is more convenient to fix, and can be fixed to the top rail 1 without punching holes in the top rail 1.

[0044] like Fig.17 As shown, the bottom of the top rail 1 of the curtain mechanism in the prior art is not open, and a hole needs to be punched at the bottom of the top rail 1, which then cooperates with the raised portion at the bottom of the cord reel 2 to achieve a fixing effect. Once the hole is punched, the fixed position cannot be changed, resulting in the cord reel 2 being unable to move as required. However, the present application can lock and unlock the cord reel 2 through the locking assembly 5, so that the cord reel 2 can move along the direction of the top rail 1 to meet different usage requirements.

[0045] The top rail 1 of the curtain mechanism in the prior art is also provided with end covers 7 on both sides, and the end covers 7 also need to be drilled from the bottom and fixed with screws to the top rail 1 (see Fig.17 The bottom of the middle top rail 1); and the present application is provided with a fixing member 6, the fixing member 6 is fixed to the top rail 1, and then the end cover 7 covers the top rail 1 from the side, and the fixation is achieved without drilling.

[0046] Moreover, the size of the existing curtain mechanism is customized, and the size of the curtain mechanism will affect the position of the punching holes (the number of punching holes and the spacing between holes will be different for different product sizes), which is very inconvenient to assemble. The present application is based on the above-mentioned locking assembly 5 and fixing part 6, which can solve this technical problem without punching holes.

[0047] like Figure 4-8As shown, at least one wire reel 2 and a first rotating member 3 are arranged in the top rail 1, and the first rotating member 3 is inserted into the wire reel 2, so that the wire reel 2 can be driven by the first rotating member 3 to rotate relative to the top rail 1; specifically, the wire reel 2 includes a support 21 and a second rotating member 22 arranged in the support 21, and the second rotating member 22 can be driven by the first rotating member 3 to rotate relative to the top rail 1. A plurality of rolling components 4 are arranged in the support 21 to abut against the second rotating member 22, and the second rotating member 22 is formed with a plurality of recessed portions 221 along its inner wall, and a plurality of protrusions 31 are formed on the surface of the first rotating member 3 to match the recessed portions 221. The recessed portions 211 abut against the protrusions 31, so that the first rotating member 3 can drive the second rotating member 22 to rotate. By providing the rolling component 4, the friction of the second rotating member 22 can be reduced, so that the second rotating member 22 can roll more smoothly, and the resistance and noise during use can also be reduced, thereby improving the use experience.

[0048] The support 21 includes a base 211 and a top cover 212 matched with the base 211. The rolling components 4 are respectively arranged on both sides of the base 211 and the top cover 212. The base 211 and the top cover 212 are respectively provided with a groove 23. The groove 23 is provided with at least one mounting portion 231. The rolling component 4 is abutted against the mounting portion 231 and is located on the groove 23. In this embodiment, one groove 23 is provided with two mounting portions 231, and the rolling component 4 is provided with four, which are respectively provided in the groove 23 on the base 211 and the groove 23 on the top cover 212 through the mounting portion 231.

[0049] At least one tilting block 24 that cooperates with the second rotating member 22 is provided on the base 211. By providing the tilting block 24, the second rotating member 22 is guided by the inclined surface of the tilting block 24 to transition and rotate more smoothly, so that the second rotating member 22 can rotate more easily and labor-savingly, further improving the smoothness of the rotation of the second rotating member 22 and further reducing resistance and noise. In this embodiment, two tilting blocks 24 are provided.

[0050] like Fig.12 As shown, the rolling assembly 4 includes a roller 41, which abuts against the second rotating member 22. A through hole 42 is opened in the middle of the roller 41. An axle 43 passes through the through hole 42 and cooperates with the mounting portion 231 so that the second rotating member 22 rotates to drive the roller 41 to rotate. A limit member 44 is provided at one end of the axle 43. By providing the limit member 44, the axle 43 can be prevented from falling out of the mounting portion 231.

[0051] like Figure 6As shown, at least one mounting hole 2111 is respectively provided on both sides of the base 211, and the top cover 212 is provided with at least one mounting block 2121 matching with the mounting hole 2111, so that the base 211 and the mounting portion 231 are fixed, and the mounting block 2121 is elastic. For details, please refer to the snap-on connection method, which will not be described in detail here.

[0052] like Figure 13-14 As shown, at least one locking assembly 5 is provided at the bottom of the top rail 1, and the locking assembly 5 includes a bottom block 51 and a top block 52. The bottom block 51 is located at the bottom of the top rail 1, and the top block 52 is located in the cable reel 2. An assembly block 53 is passed through the bottom block 51 and connected to the top block 52. A gripping block 54 is provided at one end of the assembly block 53 away from the top block 52. By providing the locking assembly 5, the gripping block 54 is moved, and the top block 52 clamps the cable reel 2, so that the cable reel 2 can be fixed in the top rail 1 to prevent it from moving. In addition, due to the provision of the locking assembly 5, the top rail 1 can be effectively prevented from being punched, thereby reducing the number of holes to be punched.

[0053] like Figure 5 As shown, a first groove body 12 and a second groove body 13 are respectively provided at the adjacent two ends of the top rail 1, and a plurality of connecting parts 14 are provided on the inner wall of the top rail 1. The first groove body 12 is used for sticking Velcro inserts to facilitate subsequent adhesion of the fabric, and the second groove body 13 is used for subsequent installation of curtain installation codes.

[0054] like Figure 1 , Figure 5 , Figure 9-11 As shown, a fixing member 6 is provided at one end of the top rail 1, and the fixing member 6 is located between the end cover 7 and the top rail 1. The fixing member 6 includes a plate body 61 and at least one first fixing portion 62 extending outward, and the first fixing portion 62 is against the second groove body 13. The fixing member 6 is a sheet metal and can be used to fix the motor 8 of the curtain mechanism, so that there is no need to drill holes in the top rail 1, and the motor 8 and the top rail 1 can be fixed by only the fixing member 6.

[0055] A plate hole 63 is defined in the middle of the plate body 61 , and a second fixing portion 64 is disposed in the plate hole 63 . Two sides of the plate body 61 are respectively recessed to form a receiving portion 65 .

[0056] like Figure 15-16 As shown, specifically, the motor 8 is arranged in the first rotating member 3, and the driving section of the motor 8 is provided with a mounting block 81 connected to the first rotating member 3 to drive the first rotating member 3 to rotate; the motor 8 can pass through the two middle holes of the plate body 61, and the motor 8 can be locked by screws to fix the motor 8 in the top rail 1. At this time, the second fixing portion 64 may not extend outward; or the motor 8 can also be connected through the second fixing portion 64 (such as Fig.11As shown, at this time, the second fixing portion 64 extends outward along the direction of the top rail 1), so that the motor 8 is fixed in the top rail 1; and by providing the connecting portion 14, there is no need to drill a hole at the rear end of the top rail 1, and the assembly can be achieved by simply fixing the motor 8 to the fixing member 6 and then fixing the fixing member 6 to the connecting portion 14.

[0057] Two end covers 7 are detachably connected at both ends of the top rail 1. The two end covers 7 are respectively a first cover body 71 and a second cover body 72. The first cover body 71 is provided with a first connecting block 711 along the direction of the top rail 1. The first connecting block 711 is against the second groove body 13 to play a fixing role. The second cover body 72 is provided with a plurality of second connecting blocks 721 along the direction of the top rail 1. The second connecting block 721 is located in the accommodating portion 65. The fixing member 6 is connected to the connecting portion 14 by screws to fix the fixing member 6 to the top rail 1. The second cover body 72 cooperates with the second connecting block 721 to further fix the fixing member 6 in the top rail 1 and cover the fixing member 6. There is no trace of punching on the entire top rail 1, and the overall appearance is beautiful.

[0058] like Figure 1-2 As shown, two limit bars 15 are also provided at the bottom of the top rail 1. The two limit bars 15 are respectively provided on both sides of the opening 11. The end cover 7 and the locking assembly 5 cooperate with the limit bars 15 to ensure that the locking assembly 5 and the end cover 7 always remain horizontal and cannot rotate.

[0059] The technical effects of the present invention are mainly reflected in the following aspects:

[0060] It is quiet and easy to assemble.

[0061] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
