For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0050] In one embodiment of the present invention, referring to Figure 1-Figure 15 , a rolling roller mechanism 200 is provided, including a winding roller 210 and a rolling curtain 220 wound outside the winding roller 210. The winding roller 210 includes a first roller body 230, a second roller body 240 and a first adjustment mechanism 250.

[0051] Among them, refer to Figure 11-13 The first roller body 230 and the second roller body 240 are both rod-shaped and hollow roller bodies. One end of the second roller body 240 is movably connected to the hollow cavity of the first roller body 230 and can be extended and retracted relative to the first roller body 230.

[0052] Among them, refer to Figure 11-13 The first adjustment mechanism 250 is used to lock or loosen the first roller body 230 and the second roller body 240 , and when loosened, the second roller body 240 can be extended or retracted from the first roller body 230 to adjust the axial length of the winding roller 210 .

[0053] Compared with the prior art, the above one or more technical solutions in the rolling roller mechanism provided by the embodiment of the utility model have at least one of the following technical effects:

[0054] Reference Figure 11-13 When in use, first loosen the first roller body 230 and the second roller body 240 through the first adjusting mechanism 250, at this time the second roller body 240 can be extended and retracted relative to the first roller body 230, so as to adjust the axial length of the winding roller 210. After the axial length of the winding roller 210 is adjusted to an appropriate size, lock the first roller body 230 and the second roller body 240 through the first adjusting mechanism 250, at this time the second roller body 240 cannot be extended and retracted relative to the first roller body 230; then cut the rolling curtain 220 along the axial length of the winding roller 210 according to the length of the winding roller 210, so that the sizes of the winding roller 210 and the rolling curtain 220 can adapt to the sizes of windows of various user households. The operation is simple and can meet the needs of users.

[0055] Reference Figure 13-Figure 15 The first roller body 230 and the second roller body 240 are provided with a first contact gap 239 along the radial direction of the winding roller 210, and the first adjustment mechanism 250 is used to adjust the first contact gap 239, thereby locking or loosening the first roller body 230 and the second roller body 240. The first adjustment mechanism 250 reduces the first contact gap 239 between the first roller body 230 and the second roller body 240, so that the inner wall of the first roller body 230 and the outer wall of the second roller body 240 are pressed tightly, thereby locking the first roller body 230 and the second roller body 240; the first adjustment mechanism 250 increases the first contact gap 239 between the first roller body 230 and the second roller body 240, so that the inner wall of the first roller body 230 and the outer wall of the second roller body 240 are no longer pressed tightly, thereby loosening the first roller body 230 and the second roller body 240.

[0056] Reference Figure 13-Figure 15The first adjustment mechanism 250 includes a first clamping member 251 and a first adjustment member 255. The first clamping member 251 abuts against the second roller body 240, and one end of the first adjustment member 255 is connected to the first clamping member 251. The first adjustment member 255 is used to drive the first clamping member 251 to move so as to reduce or increase the first contact gap 239 between the first roller body 230 and the second roller body 240, thereby locking or loosening the first roller body 230 and the second roller body 240, so as to facilitate the second roller body 240 to extend or retract from the first roller body 230. The first clamping member 251 is driven to move by the first adjusting member 255 to press the second roller body 240, and the first contact gap 239 between the second roller body 240 and the first roller body 230 is reduced, so that the inner wall of the first roller body 230 and the outer wall of the second roller body 240 are pressed tightly, thereby locking the first roller body 230 and the second roller body 240, so that the second roller body 240 cannot slide relative to the first roller body 230 to expand and contract. The first clamping member 251 is driven to move by the first adjusting member 255 to loosen the second roller body 240, and the first contact gap 239 between the first roller body 230 and the second roller body 240 is increased, so that the inner wall of the first roller body 230 and the outer wall of the second roller body 240 are no longer pressed tightly, thereby loosening the first roller body 230 and the second roller body 240, so that the second roller body 240 can slide relative to the first roller body 230 to expand and contract.

[0057] Reference Figure 13-Figure 15 The second roller body 240 is provided with a first receiving groove 241 along its axial direction, and the first clamping member 251 is accommodated in the first receiving groove 241; a first opening 242 for the first adjusting member 255 to pass through is opened on one side of the groove wall of the first receiving groove 241, and the width of the first opening 242 is smaller than the maximum width of the first clamping member 251, so as to limit the first clamping member 251 and install it in the first receiving groove 241.

[0058] Reference Figure 13-Figure 15The first clamping member 251 is provided with at least one first threaded hole 252, the first adjusting member 255 is a first screw, the outer wall of the first roller body 230 is provided with at least one first insertion hole 231, the screw rod of the first screw passes through the first insertion hole 231 and the first opening 242 in sequence and is screwed with the first threaded hole 252, and the nut of the first screw is located outside the first insertion hole 231; when the nut of the first screw is turned, the first screw drives the first clamping member 251 to move to adjust the distance between the first clamping member 251 and the nut of the first screw, thereby reducing or increasing the first contact gap 239 between the first roller body 230 and the second roller body 240. Specifically, by tightening the first screw, the first clamping member 251 is driven to move toward the nut of the first screw, thereby reducing the distance between the first clamping member 251 and the nut of the first screw, and further reducing the first contact gap 239 between the first roller body 230 and the second roller body 240, so that the inner wall of the first roller body 230 and the outer wall of the second roller body 240 are pressed tightly to lock the first roller body 230 and the second roller body 240, so that the second roller body 240 cannot slide relative to the first roller body 230 to expand and contract. Loosening the first screw drives the first clamping member 251 to move away from the nut of the first screw, thereby increasing the distance between the first clamping member 251 and the nut of the first screw, and further increasing the first contact gap 239 between the first roller body 230 and the second roller body 240, so that the inner wall of the first roller body 230 and the outer wall of the second roller body 240 are released from the tight contact, so as to loosen the first roller body 230 and the second roller body 240, so that the second roller body 240 can slide relative to the first roller body 230 to extend and retract.

[0059] Also, refer to Figure 13-Figure 15 The first opening 242 serves as an avoidance function. When the first screw is loosened to loosen the first roller body 230 and the second roller body 240, the second roller body 240 expands and contracts in the first roller body 230. The second roller body 240 avoids the first screw through the first opening 242 to avoid interference between the second roller body 240 and the first screw, thereby ensuring that the second roller body 240 expands and contracts smoothly in the first roller body 230.

[0060] Preferably, refer to Figure 13-Figure 15The outer wall of the first roller body 230 is provided with a plurality of first insertion holes 231 along its axial direction, and the first clamping member 251 is provided with a plurality of first threaded holes 252 along its length direction, and the plurality of first threaded holes 252 are respectively arranged in one-to-one correspondence with the plurality of first insertion holes 231. There are a plurality of first screws, and the screw rods of the plurality of first screws respectively pass through the plurality of first insertion holes 231 and the first opening 242 in sequence and are respectively screwed with the plurality of first threaded holes 252. The plurality of first screws are respectively screwed with the plurality of first threaded holes 252 of the first clamping member 251, thereby improving the firmness of the first adjustment mechanism 250 in locking the first roller body 230 and the second roller body 240. Even if one of the screws is loose, the first roller body 230 and the second roller body 240 will not be separated, and the structure is stable.

[0061] In some embodiments, the first adjustment mechanism 250 includes a first adjustment member 255, one end of which passes through the first roller body 230 and is used to tighten or loosen the outer wall of the second roller body 240. When the first adjustment member 255 loosens the second roller body 240, the second roller body 240 can be extended or retracted from the first roller body 230 to adjust the axial length of the winding roller 210. The first adjustment member 255 includes at least one third screw (not shown in the figure). The outer wall of the first roller body 230 is provided with at least one third threaded hole (not shown in the figure). The third screw is screwed into the third threaded hole, and the screw of the third screw is used to tighten the outer wall of the second roller body 240. When the third screw is tightened, the screw of the third screw is pressed against the outer wall of the second roller body 240, thereby locking the first roller body 230 and the second roller body 240. When the third screw is loosened, the screw of the third screw is away from the outer wall of the second roller body 240, thereby loosening the first roller body 230 and the second roller body 240.

[0062] Further, refer to Fig.11 and Fig.12 When the rolling roller mechanism 200 is not installed in the intelligent rolling mechanism 100 for use by the user, baffles 212 are detachably provided at both ends of the reel 210, and the baffles 212 are used to prevent the cross-section of the rolling curtain 220 from being misaligned. The outer periphery of the rolling curtain 220 is also wrapped with a plastic film (not shown in the figure), and the plastic film is used to prevent the rolling curtain 220 from falling apart. When the rolling roller mechanism 200 needs to be installed in the roller cover 110 of the intelligent rolling mechanism 100 for use, the plastic film and baffles 212 need to be removed at this time to facilitate the rolling curtain 220 of the rolling roller mechanism 200 to be unfolded or retracted.

[0063] In another embodiment, referring to Figure 11-13The winding roller 210 further includes a third roller body 260; the third roller body 260 is sleeved outside the second roller body 240 and makes the ends of the first roller body 230 and the third roller body 260 close to and spliced, and the peripheral edges of the ends of the third roller body 260 and the first roller body 230 spliced ​​to each other are flush; the hardness of the third roller body 260 is less than the hardness of the second roller body 240, so that the axial length of the third roller body 260 can be cut, refer to Fig.10 When it is necessary to adjust the axial length of the winding roller 210 to cut the axial length of the third roller body 260, the cutting device 300 can be used to first cut the axial length of the roller curtain 220 extending from the winding roller 210 outside the third roller body 260, and then the cutting device 300 can be used to cut the axial length of the third roller body 260. Since the hardness of the second roller body 240 is greater than that of the third roller body 260, the second roller body 240 cannot be cut at this time, and at most only a cut mark will be left on the peripheral wall of the second roller body 240. Then, the baffles 210 on both sides of the winding roller 210 are 2 and the plastic film wrapped around the rolling curtain 220 are removed, and then the rolling curtain 220 is unfolded until the surfaces of the first roller body 230 and the second roller body 240 are exposed, and the first roller body 230 and the second roller body 240 are loosened by the first adjusting mechanism 250, and a part of the second roller body 240 is retracted back into the first roller body 230, so that the end of the second roller body 240 away from the first roller body 230 and the end of the third roller body 260 away from the first roller body 230 are flush or nearly flush, and finally the first roller body 230 and the second roller body 240 are locked by the first adjusting mechanism 250.

[0064] Alternatively, in some embodiments, reference Fig. 9The third roller body 120 includes a plurality of roller segments 261 that are all detachably mounted on the outside of the second roller body 240, so that at least one roller segment 261 of the third roller body 260 can be removed to shorten the axial length of the third roller body 260; the plurality of roller segments 261 can be a plurality of roller segments 261 of different lengths or the same length that abut against each other. When the rolling curtain 220 outside the third roller body 260 is cut, the baffles 212 on both sides of the winding roller 210 and the plastic film wrapped around the rolling curtain 220 are removed, and then some of the roller segments 261 are removed as needed, so that the end of the outermost roller segment 261 of the remaining plurality of roller segments 261 of the third roller body 260 mounted on the outside of the second roller body 240 is flush or nearly flush with the end of the rolling curtain 220 that is away from the first roller body 230 along the axial direction of the second roller body 240, and the remaining plurality of roller segments 261 mounted on the second roller body 240 stably support the rolling curtain 220. The rolling curtain 220 is then unfolded until the surfaces of the first roller body 230 and the second roller body 240 are exposed, and the first roller body 230 and the second roller body 240 are loosened by the first adjusting mechanism 250, and a part of the second roller body 240 is retracted back into the first roller body 230, so that one end of the second roller body 240 away from the first roller body 230 and one end of the rolling curtain 220 axially away from the first roller body 230 or the end of the outermost roller segment 261 of the remaining multiple roller segments 261 outside the second roller body 240 are flush or nearly flush.

[0065] Further, refer to Fig.13 The outer walls of the first roller body 230 and the third roller body 260 are provided with a connecting groove 232, and the connecting groove 232 is used for fixing one end of the rolling curtain 220 therein. One end of the rolling curtain 220 can be fixedly installed in the connecting groove 232 by means of snap connection, bonding or screw connection, so that when the winding roller 210 rotates, it can drive the rolling curtain 220 to unfold or retract.

[0066] In another embodiment, referring to Figure 6 and Figure 7 , also provided is an intelligent rolling shutter mechanism 100, comprising a roller cover 110, a driving mechanism 170 and the above-mentioned rolling shutter roller mechanism 200; the driving mechanism 170 is arranged at one end of the roller cover 110, and the driving mechanism 170 is connected to the winding roller 210 to drive the winding roller 210 and the rolling shutter 220 to rotate, so that the rolling shutter 220 is unfolded or retracted, thereby adjusting the light intensity in the room by the degree to which the rolling shutter 220 blocks the window.

[0067] Reference Figure 1 and Figure 2 The roller cover 110 includes a first cover shell 120 , a second cover shell 130 and a second adjustment mechanism 140 .

[0068] Among them, refer to Figure 1 and Figure 2The first housing 120 and the second housing 130 are both rod-shaped and hollow housings. One end of the second housing 130 is movably connected to the hollow cavity of one end of the first housing 120 and can be extended and retracted relative to the first housing 120.

[0069] Among them, refer to Figure 1 and Figure 2 The second adjustment mechanism 140 is used to lock or loosen the first cover shell 120 and the second cover shell 130 , and when loosened, the second cover shell 130 can be extended or retracted from the first cover shell 120 to adjust the axial length of the roller cover 110 .

[0070] Compared with the prior art, the above one or more technical solutions in the roller cover 110 for the smart rolling shutter mechanism 100 provided in the embodiment of the utility model have at least one of the following technical effects:

[0071] Reference Figure 1 and Figure 2 When in use, the first cover shell 120 and the second cover shell 130 are first loosened by the second adjustment mechanism 140, and the second cover shell 130 can be extended relative to the first cover shell 120, thereby adjusting the axial length of the roller cover 110 so that the size of the roller cover 110 can adapt to the size of windows of various user households. The operation is simple and can meet the needs of users. After the axial length of the roller cover 110 is adjusted to a suitable size, the first cover shell 120 and the second cover shell 130 are locked by the second adjustment mechanism 140, and the second cover shell 130 cannot be extended relative to the first cover shell 120.

[0072] Reference Figure 2-Figure 4 The first cover 120 and the second cover 130 are provided with a second contact gap 129 along the height direction of the roller cover 110, and the second adjustment mechanism 140 is used to adjust the second contact gap 129, thereby locking or loosening the first cover 120 and the second cover 130. The second adjustment mechanism 140 reduces the second contact gap 129 between the first cover 120 and the second cover 130, so that the inner wall of the first cover 120 and the outer wall of the second cover 130 are pressed tightly, thereby locking the first cover 120 and the second cover 130; the second adjustment mechanism 140 increases the second contact gap 129 between the first cover 120 and the second cover 130, so that the inner wall of the first cover 120 and the outer wall of the second cover 130 are no longer pressed tightly, thereby loosening the first cover 120 and the second cover 130.

[0073] Reference Figure 2-Figure 4The second adjustment mechanism 140 includes a second clamping member 141 and a second adjustment member 145. The second clamping member 141 abuts against the second housing 130, and one end of the second adjustment member 145 is connected to the second clamping member 141. The second adjustment member 145 is used to drive the second clamping member 141 to move to reduce or increase the second contact gap 129 between the first housing 120 and the second housing 130, thereby locking or loosening the first housing 120 and the second housing 130. The second adjustment member 145 drives the second clamping member 141 to move and press the second housing 130, and the second contact gap 129 between the first housing 120 and the second housing 130 is reduced, so that the inner wall of the first housing 120 and the outer wall of the second housing 130 are pressed against each other, thereby locking the first housing 120 and the second housing 130, so that the second housing 130 cannot slide relative to the first housing 120 to extend or retract. The second clamping member 141 is driven to move and the second cover 130 is loosened by the second adjusting member 145 to increase the second contact gap 129 between the first cover 120 and the second cover 130, so that the inner wall of the first cover 120 and the outer wall of the second cover 130 are released from the tight contact, thereby loosening the first cover 120 and the second cover 130, so that the second cover 130 can slide relative to the first cover 120 to extend and retract.

[0074] Reference Figure 2-Figure 4 The second housing 130 is provided with a second receiving groove 131 along its axial direction, and the second clamping member 141 is accommodated in the second receiving groove 131; a second opening 132 for the second adjusting member 145 to pass through is opened on one side wall of the second receiving groove 131, and the width of the second opening 132 is smaller than the maximum width of the second clamping member 141, so as to limit the second clamping member 141 and install it in the second receiving groove 131.

[0075] Reference Figure 2-Figure 4The second clamping member 141 is provided with at least one second threaded hole 142, the second adjusting member 145 is a second screw, the outer wall of the first cover shell 120 is provided with at least one second insertion hole 121, the screw rod of the second screw passes through the second insertion hole 121 and the second opening 132 in sequence and is screwed with the second threaded hole 142, and the nut of the second screw is located outside the second insertion hole 121; when the nut of the second screw is turned, the second screw drives the second clamping member 141 to move to adjust the distance between the second clamping member 141 and the nut of the second screw, thereby reducing or increasing the second contact gap 129 between the first cover shell 120 and the second cover shell 130. Specifically, by tightening the second screw, the second clamping member 141 is driven to move toward the nut of the second screw, thereby reducing the distance between the second clamping member 141 and the nut of the second screw, and further reducing the second contact gap 129 between the first cover shell 120 and the second cover shell 130, so that the inner wall of the first cover shell 120 and the outer wall of the second cover shell 130 are pressed against each other, so as to lock the first cover shell 120 and the second cover shell 130, so that the second cover shell 130 cannot slide relative to the first cover shell 120 for extension and retraction. Loosening the second screw drives the second clamping member 141 to move away from the nut of the second screw, thereby increasing the distance between the second clamping member 141 and the nut of the second screw, and further increasing the second contact gap 129 between the first cover shell 120 and the second cover shell 130, so that the inner wall of the first cover shell 120 and the outer wall of the second cover shell 130 are released from the tight contact, so as to loosen the first cover shell 120 and the second cover shell 130, so that the second cover shell 130 can slide relative to the first cover shell 120 for extension and retraction.

[0076] Also, refer to Figure 2-Figure 4 The second accommodating groove 131 plays an avoidance role. When the second screw is loosened to loosen the first cover 120 and the second cover 130, the second cover 130 is extended and retracted in the first cover 120. The second cover 130 avoids the second screw through the second accommodating groove 131, avoiding interference between the second cover 130 and the second screw, thereby ensuring that the second cover 130 is smoothly extended and retracted in the first cover 120.

[0077] Preferably, refer to Figure 2-Figure 4The outer wall of the first housing 120 is provided with a plurality of second insertion holes 121 along its axial direction, and the second clamping member 141 is provided with a plurality of second threaded holes 142 along its length direction, and the plurality of second threaded holes 142 are respectively arranged in one-to-one correspondence with the plurality of second insertion holes 121. A plurality of second screws are provided, and the screw rods of the plurality of second screws respectively pass through the plurality of second insertion holes 121 and the second opening 132 in sequence and are respectively screwed with the plurality of second threaded holes 142. The plurality of second screws are respectively screwed with the plurality of second threaded holes 142 of the second clamping member 141, thereby improving the firmness of the second adjustment mechanism 140 in locking the first housing 120 and the second housing 130. Even if one of the screws is loosened, the first housing 120 and the second housing 130 will not be separated, and the structure is stable.

[0078] In some embodiments, the second adjustment mechanism 140 includes a second adjustment member 145, one end of which passes through the first housing 120 and is used to tighten or loosen the outer wall of the second housing 130. When the second adjustment member 145 loosens the second housing 130, the second housing 130 can be extended or retracted from the first housing 120 to adjust the axial length of the roller cover 110. The second adjustment member 145 includes at least one fourth screw (not shown in the figure). The outer wall of the first housing 120 is provided with at least one fourth threaded hole (not shown in the figure). The fourth screw is screwed into the fourth threaded hole, and the screw of the fourth screw is used to tighten the outer wall of the second housing 130. When the fourth screw is tightened, the screw of the fourth screw is pressed against the outer wall of the second housing 130, thereby locking the first housing 120 and the second housing 130. When the fourth screw is loosened, the screw of the fourth screw is away from the outer wall of the second housing 130, thereby loosening the first housing 120 and the second housing 130.

[0079] In another embodiment, referring to Figure 1 and Figure 2The roller cover 110 further includes a third cover shell 150 and a third adjustment mechanism 160. The third cover shell 150 is a rod-shaped and hollow shell, and the other end of the second cover shell 130 is movably connected to the hollow cavity of one end of the third cover shell 150 and can be extended and retracted relative to the third cover shell 150. The third adjustment mechanism 160 is used to lock or loosen the second cover shell 130 and the third cover shell 150, and when loosened, the second cover shell 130 can be extended or retracted from the third cover shell 150 to adjust the axial length of the roller cover 110. Among them, the structure of the third adjusting mechanism 160 locking or loosening the second cover shell 130 and the third cover shell 150 is consistent with the structure of the second adjusting mechanism 140 locking or loosening the first cover shell 120 and the second cover shell 130. Therefore, the user can choose to fix the second cover shell 130 and the third cover shell 150 through the third adjusting mechanism 160 so that the second cover shell 130 can be extended and retracted in the first cover shell 120; or fix the first cover shell 120 and the second cover shell 130 through the second adjusting mechanism 140 so that the second cover shell 130 can be extended and retracted in the third cover shell 150, which is convenient for users to use.

[0080] Further, refer to Figure 1 and Figure 2 The first cover shell 120 and the third cover shell 150 have the same structure. The upper surface of the first cover shell 120 and the third cover shell 150 can be used as the installation top surface, which can ensure that the heights of the two installation top surfaces are the same. The installation top surface can be equipped with mounting parts for fixing the roller cover 110 on the installation surface (for example: wall, windowsill, ceiling).

[0081] Alternatively, in other embodiments, the third housing 150 is movably connected to the hollow cavity at the other end of the first housing 120 and can be extended and retracted relative to the first housing 120. The third adjustment mechanism 160 is used to lock or release the first housing 120 and the third housing 150, and when released, the third housing 150 can be extended or retracted from the first housing 120 to adjust the axial length of the roller cover 110. The structure of the third adjustment mechanism 160 locking or releasing the first housing 120 and the third housing 150 is consistent with the structure of the second adjustment mechanism 140 locking or releasing the first housing 120 and the second housing 130. Therefore, the user can independently choose to fix the first housing 120 and the third housing 150 through the third adjustment mechanism 160 so that the second housing 130 can be extended and retracted in the first housing 120; or fix the first housing 120 and the second housing 130 through the second adjustment mechanism 140 so that the third housing 150 can be extended and retracted in the first housing 120, which is convenient for the user.
