[0037] In this embodiment, refer to Figure 1-Figure 6 , a cutting device 300 for an intelligent rolling blind mechanism is provided, comprising a cutting shell 310 and a cutting knife 320 .

[0038] Among them, refer to Figure 1 and Figure 4 The cut housing 310 is used to be installed at the end of the roller cover 110 of the intelligent rolling blind mechanism 100. The cut housing 310 is provided with a mounting groove 311, and the mounting groove 311 is used for the rolling blind roller mechanism 200 of the intelligent rolling blind mechanism 100 to extend therein. Preferably, the mounting groove 311 is circular, and the rolling blind roller mechanism 200 is cylindrical, so that the rolling blind roller mechanism 200 is adapted to extend into the mounting groove 311.

[0039] Among them, refer to Figure 1 and Figure 5 The cutting blade 320 is disposed on the cutting housing 310 and can be retracted to cut the rolling curtain 220 and / or the winding roller 210 of the rolling curtain roller mechanism 200. Optionally, the rolling curtain is a curtain fabric.

[0040] Compared with the prior art, the above one or more technical solutions in the cutting device 300 for the intelligent rolling shutter mechanism provided by the embodiment of the utility model have at least one of the following technical effects:

[0041] Reference Figure 1 , Figure 2 and Figure 5When cutting, one end of the rolling curtain roller mechanism 200 is connected to the driving mechanism 140 of the intelligent rolling curtain mechanism 100, the cutting shell 310 is installed on the end of the roller cover 110, and the end of the rolling curtain roller mechanism 200 to be cut is extended into the installation groove 311, and the rolling curtain roller mechanism 200 is driven to rotate by the driving mechanism 140, and then the cutting knife 320 moves toward the rolling curtain roller mechanism 200, and the cutting knife 320 cuts the rolling curtain 220 when it contacts the rolling curtain 220, and the cutting knife 320 can also cut the winding roller 210 when it contacts the peripheral wall of the winding roller 210, so that the user can cut the axial length of the rolling curtain 220 extending from the winding roller 210 by himself, and can also cut the axial length of the winding roller 210 to adapt to the sizes of windows of various user families. It is simple to operate and convenient for users to use. It is understandable that in some cases, it is not necessary to cut the winding roller 210, but only cut the rolling curtain 220. For example, when the winding roller 210 is composed of multiple roller segments 211, it is only necessary to cut the length of the rolling curtain 220 and remove some of the roller segments 211.

[0042] Reference Figure 5 and Figure 6 The cutting knife 320 has an arc-shaped blade 321 at one end close to the mounting groove 311. The arc-shaped blade 321 is used for cutting the rolling curtain 220 and / or the winding roller 210. The arc-shaped blade 321 is conducive to cutting the rolling curtain 220 and / or the winding roller 210, making the cutting surface neat.

[0043] Reference Figure 5 and Figure 6 The cutting shell 310 is provided with a cavity 312 and a through slot 313. The two ends of the through slot 313 are respectively connected to the cavity 312 and the mounting slot 311. The cutting knife 320 is arranged in the cavity 312. The through slot 313 is used for the cutting knife 320 to pass through when it is extended or retracted, so that the cutting knife 320 extends into the mounting slot 311 to cut the rolling curtain 220 and / or the winding roller 210, or the cutting knife 320 is retracted into the cavity 312. During cutting, the rolling curtain roller mechanism 200 is rotated in the roller cover 110 through the driving mechanism 140, and the cutting knife 320 extends into the installation groove 311 and contacts the rolling curtain 220 to cut the rolling curtain 220; the cutting knife 320 can also contact the peripheral wall of the winding roller 210 and cut the winding roller 210, so that the cutting knife 320 cuts the winding roller 210, that is, the cutting knife 320 can cut the rolling curtain 220 and can also cut the winding roller 210; after cutting, the cutting knife 320 retracts into the cavity 312, and the cutting knife 320 is not exposed, so as to avoid the user's accidental cutting of the hand, and the safety is good.

[0044] Reference Figure 5 and Figure 6The cutting knife 320 is fixedly provided with a knife holder 330, and the center of the cutting knife 320 is fixedly connected to the knife holder 330, and the installation is stable. The cutting knife 320 can be fixedly connected to the knife holder 330 by means of clamping, welding, or screwing. The cavity 312 is provided with an adjusting member 340, and the adjusting member 340 is connected to the knife holder 330 to drive the knife holder 330 to move back and forth, thereby driving the cutting knife 320 to extend and retract, that is, driving the cutting knife 320 to extend into the installation slot 311 or retract into the cavity 312.

[0045] Reference Figure 5 and Figure 6 The adjusting member 340 is a screw rod, which is rotatably connected to the cavity 312. The tool holder 330 is fixed with a nut 331, which is threadedly connected to the screw rod. Rotating the screw rod can drive the tool holder 330 to move back and forth, thereby driving the cutting knife 320 to extend and retract. That is, by rotating the screw rod, the nut 331 is driven to move back and forth along the screw rod, thereby driving the tool holder 330 to move back and forth, and then driving the cutting knife 320 to extend and retract. The structure is simple. The screw rod can be rotated by manpower or by a driving unit. The driving unit can be a motor. The rotating shaft of the motor is fixedly connected to one end of the screw rod to drive the screw rod to rotate.

[0046] Reference Figure 5 and Figure 6 The screw rod has a driving end 341 at one end, and the driving end 341 extends out of the cutting housing 310. The driving end 341 can be a nut or a knob handle. When the driving end 341 is a nut, the nut can be matched with a tool (such as a screwdriver, a wrench, etc.), so that the user can use the tool to twist the nut to drive the screw rod to rotate, thereby driving the cutting knife 320 to extend and retract; when the driving end 341 is a knob handle, the user can directly twist the knob handle to drive the screw rod to rotate, thereby driving the cutting knife 320 to extend and retract, which is convenient for operation. Alternatively, the outer wall of the cutting housing 310 is provided with a socket 319 extending into the cavity 312, and the driving end 341 is a nut and is located in the socket 319. The user can use a tool (such as a screwdriver) to reach into the socket 319 to twist the nut to drive the screw rod to rotate, thereby driving the cutting knife 320 to extend and retract.

[0047] Reference Figure 5 and Figure 6 The adjusting member 340 is provided with a positioning portion 342, and the cavity 312 is provided with a positioning groove 314. The positioning portion 342 can rotate in the positioning groove 314, and the positioning groove 314 is used to limit the positioning portion 342 so that the adjusting member 340 cannot move along the extension direction of the cutting knife 320. That is, the adjusting member 340 can rotate in the cavity 312, but cannot move along the extension direction of the cutting knife 320, so that when the adjusting member 340 (screw) is rotated, the nut 331 can be driven to reciprocate along the screw, thereby driving the knife holder 330 to reciprocate, and then driving the cutting knife 320 to extend and retract, and the structure is stable.

[0048] Reference Figure 5 and Figure 6 One of the knife holder 330 and the cavity 312 is provided with a guide block 332, and the other is provided with a guide groove 315. The guide block 332 is slidably connected with the guide groove 315, so that the cutting knife 320 can be extended and retracted along the radial direction of the rolling roller mechanism 200 under the drive of the adjustment member 340. The guide block 332 cooperates with the guide groove 315 to play a guiding role, so that the cutting knife 320 can be stably extended and retracted, and the structure is stable.

[0049] In a specific embodiment, the guide groove 315 is in the shape of an elongated strip and is disposed on the cavity wall of the cavity 312, and the guide block 332 is disposed on the tool holder 330 so that the tool holder 330 can reciprocate along the guide groove 315 through the guide block 332; wherein, a limit surface is provided at both ends of the guide groove 315, and the two limit surfaces are used to limit the travel of the guide block 332 along the guide groove 315, that is, to limit the travel of the cutting knife 320 to extend and retract, so that the cutting knife 320 can move within a reasonable travel.

[0050] In other embodiments, the guide block 332 is in an elongated shape and is disposed on the cavity wall of the cavity 312 , and the guide groove 315 is disposed on the tool holder 330 , so that the tool holder 330 can reciprocate along the guide block 332 through the guide groove 315 .

[0051] Reference Figure 5 and Figure 6 The outer wall of the cutting housing 310 is provided with an indicating slot 316 communicating with the cavity 312, and the knife holder 330 is fixed with an indicating block 333, which is movably arranged in the indicating slot 316. The indicating block 333 moves with the cutting knife 320 to indicate the length of the cutting knife 320 extending into the installation slot 311. That is, when the adjusting member 340 drives the cutting knife 320 to perform telescopic movement, the indicating block 333 will move along the length direction of the indicating slot 316 with the cutting knife 320. The user can know the extent (length) of the cutting knife 320 extending into the installation slot 311 or the extent of the cutting knife 320 retracting into the cavity 312 through the position of the indicating block 333 on the indicating slot 316, so that the user can decide whether to continue to drive the cutting knife 320 to perform telescopic movement through the adjusting member 340, and the structure is reliable.

[0052] Reference Figure 6An elastic member 360 is disposed between the knife holder 330 and the cavity 312 , and the elastic member 360 is used to generate resistance to the cutting knife 320 , so that the speed at which the cutting knife 320 extends into the installation slot 311 gradually slows down. Specifically, in the process of the adjustment member 340 driving the cutting knife 320 to extend into the installation slot 311, the elastic member 360 is stretched or compressed to generate elastic force and the elastic force gradually increases. The direction of the elastic force is opposite to the direction in which the cutting knife 320 extends into the installation slot 311, thereby generating resistance to the cutting knife 320, causing the speed at which the cutting knife 320 extends into the installation slot 311 to gradually slow down (slow down), so as to control the feed amount of the cutting knife 320 during cutting, which is beneficial to the neat cutting surface of the rolling curtain 220, and at the same time avoids the excessive feed amount of the cutting knife 320 and the clamping (clamping of the rolling curtain roller mechanism 200) causing the driving mechanism 140 (such as the driving motor) of the intelligent rolling curtain mechanism 100 to be blocked, and is beneficial for the cutting knife 320 to continue cutting the winding roller 210 after cutting the rolling curtain 220, thereby ensuring the normal operation of the cutting work.

[0053] In a specific embodiment, the elastic member 360 is a spring, and the knife holder 330 and the cavity 312 are both provided with a connecting portion 350, and the two end rings of the spring are respectively hung on the two connecting portions 350, so as to facilitate the installation of the spring. When the cutting knife 320 is inserted into the installation slot 311, the spring is stretched to generate elastic force, and the elastic force gradually increases, and the elastic force generates resistance to the cutting knife 320, so that the speed at which the cutting knife 320 is inserted into the installation slot 311 gradually slows down, so as to control the feed amount of the cutting knife 320 during cutting.

[0054] In some embodiments, the elastic member 360 is a compression spring, and the two ends of the compression spring are respectively connected or abutted to the tool holder 330 and the cavity wall of the cavity 312. When the cutting knife 320 extends into the installation groove 311, the compression spring is compressed to generate elastic force and the elastic force gradually increases. The elastic force generates resistance to the cutting knife 320, so that the speed at which the cutting knife 320 extends into the installation groove 311 gradually slows down, so as to control the feed amount of the cutting knife 320 during cutting.

[0055] Reference Figure 6 The cavity 312 has a cavity opening 312a, and the cutting housing 310 is provided with a cover plate 317, which is adapted to cover the cavity opening 312a, and the cover plate 317 can be connected to the cutting housing 310 by means of snap connection or screw connection. The cover plate 317 plays a protective role, protecting the cutting knife 320, the knife holder 330, the adjusting member 340 and the elastic member 360 in the cavity 312. Among them, the indicating groove 316 is provided through the cover plate 317.

[0056] Reference Figure 1 and Figure 2The cutting housing 310 is provided with a mounting portion 318 beside the mounting groove 311, and the mounting portion 318 is used to be detachably fixedly connected to the end of the roller cover 110, so that the cutting device 300 can be detachably fixedly mounted on the end of the roller cover 110, so that the user can use the cutting knife 320 to cut the rolling curtain 220 and / or the winding roller 210. The mounting portion 318 can be detachably fixedly mounted on the end of the roller cover 110 by means of snap connection or screw connection.

[0057] In another embodiment, referring to Figure 1-Figure 3 , a smart rolling curtain mechanism 100 is also provided, comprising a roller cover 110, a driving mechanism 140 and a rolling curtain roller mechanism 200; the driving mechanism 140 is arranged at one end of the roller cover 110, the rolling curtain roller mechanism 200 comprises a winding roller 210 and a rolling curtain 220 wound outside the winding roller, and the rolling curtain roller mechanism 200 is connected to the driving mechanism 140, and is used to drive the rolling curtain roller mechanism 200 to rotate; when the rolling curtain 220 and / or the winding roller 210 of the rolling curtain roller mechanism 200 are cut, a cutting device 300 is detachably fixed at the other end of the roller cover 110; when the smart rolling curtain mechanism 100 is installed on a mounting surface (for example: a wall, a windowsill, a ceiling) and drives the rolling curtain 220 to open and close, a cover end cap 150 is detachably fixed at the other end of the roller cover 110. The roller cover 110 can be fixed on the mounting surface by screws, and the detachable fixing includes fixing in a manner such as snap-on or screw-on.

[0058] Specifically, the driving mechanism 140 can be a driving motor, and the winding roller 210 can be a hollow roller. One end of the winding roller 210 is sleeved outside the driving motor and connected to the output shaft of the driving motor, so that the driving motor can drive the winding roller 210 and the rolling curtain 220 to rotate and cut the rolling curtain 220 and / or when the winding roller 210, the driving mechanism 140 drives the winding roller 210 and the rolling curtain 220 to rotate, and the cutting knife 320 moves toward the rolling curtain roller mechanism 200, and the cutting knife 320 cuts the rolling curtain 220 when it contacts the rolling curtain 220, and can also cut the winding roller 210 when it contacts the peripheral wall of the winding roller 210, so that the user can cut the rolling curtain 220 along the axial length of the winding roller 120 by himself, and can also cut the axial length of the winding roller 120 to adapt to the sizes of windows of various user households. It is simple to operate and can facilitate user needs. In some cases, it is also possible to cut only the rolling curtain 220 without cutting the winding roller 210. For example, when the winding roller 210 is composed of a plurality of roller segments 211, it is only necessary to cut the length of the rolling curtain 220 and remove some of the roller segments 211. The entire cutting process is simple, and the user can cut by himself. There is no need to find a manufacturer to customize the intelligent rolling curtain mechanism 100 of the corresponding size, nor is there a need to purchase a large cutting machine, which improves the user's operating experience.

[0059] Reference Figure 1 and Figure 2 The other end of the roller cover 110 is provided with an insertion groove 111, and the mounting portion 318 of the cutting shell 310 is adapted to be inserted into the insertion groove 111; the insertion groove 111 is provided with a plurality of threaded columns, and the mounting portion 318 is penetrated by a plurality of screws (not shown in the figure), and the plurality of screws are respectively screwed with the threaded holes of the plurality of threaded columns, so that the cutting shell 310 is detachably fixedly mounted on the end of the roller cover 110.

[0060] Reference Figure 1-Figure 3 When cutting, the user connects one end of the winding roller 210 to the driving mechanism 140, and the other ends of the winding roller 210 and the rolling curtain 220 extend into the installation groove 311. Then the driving mechanism 140 drives the winding roller 210 and the rolling curtain 220 to rotate, and the cutting knife 320 contacts the rolling curtain 220 to cut the rolling curtain 220. Then the cutting knife 320 contacts the peripheral wall of the winding roller 210 to cut the winding roller 210, so that the lengths of the roller cover 110, the winding roller 210 and the rolling curtain 220 can all adapt to the window. After the user has completed cutting, the cutting device 300 is removed from the other end of the roller cover 110, and the cover end cover 150 is installed on the other end of the roller cover 110, and the cut end of the winding roller 210 is connected to the cover end cover 150, and the winding roller 210 is stably installed on the roller cover 110.
