Description

Technical Field

[0001] The invention belongs to the technical field of smart home, and in particular relates to a hanging mechanism and a curtain opener and closer. Background Art

[0002] The home curtain comprises a guide and a curtain; the top of the curtain is slidably connected to the guide. The curtain opener and closer needs to be installed on the guide and can move smoothly along the guide, so as to gather or spread the curtain during the movement, thereby realizing opening or closing the curtain.

[0003] The existing curtain opener and closer includes a host and a hanging mechanism arranged on the host; the hanging mechanism is slidably connected to the guide member, and the host is used to drive the hanging mechanism to move along the guide member, and during the movement of the hanging mechanism, the curtain ring is pushed to move along the guide member, thereby driving the curtain on the guide member to gather or spread, and realizing opening or closing the curtain, which has a high degree of intelligence. However, during the process of the hanging mechanism pushing the curtain ring to move along the guide member, the ring is prone to tilt, which causes the friction between the ring and the guide member to increase, resulting in the ring and the hanging mechanism moving along the guide member not smoothly, and then causing the curtain to move not smoothly when gathering or spreading, and it is easy to get stuck; at the same time, the friction between the ring and the guide member increases, and the power required by the host to drive the curtain to gather or spread increases, resulting in increased energy consumption of the host, and low energy saving performance. Summary of the invention

[0004] The object of the present invention is to provide a hanging mechanism and a curtain opener, aiming to solve the technical problem in the prior art that when the hanging mechanism pushes the curtain hanging ring to move along the guide member, the hanging ring is prone to tilt, which increases the friction between the hanging ring and the guide member, resulting in unsmooth movement of the hanging ring and the hanging mechanism along the guide member, which in turn causes the curtain to move unsmoothly when it is gathered or spread out, and is prone to jamming.

[0005] To achieve the above-mentioned purpose, an embodiment of the present invention provides a hanging mechanism for use in a curtain opener and closeer; the hanging mechanism includes a connecting seat, a bracket, a moving assembly and a carrying plate; the first end of the bracket is plugged into the connecting seat, the second end of the bracket extends out of the connecting seat, the moving assembly is installed on the second end of the bracket and is used to be movably hung on the curtain guide; the carrying plate is used to carry the curtain ring, the first end of the carrying plate is connected to the second end of the bracket, the carrying plate is parallel to the moving direction of the moving assembly and is close to the guide when installed, and the second end of the carrying plate is away from the side of the guide and is provided with a first inclined surface and a convex portion from the outside to the inside; when the curtain is folded, the carrying plate drives a plurality of the rings located on the guide to move along the first inclined surface in sequence and pass over the convex portion to be folded and arranged on the carrying plate; when the curtain is unfolded, the carrying plate drives a plurality of the rings located thereon to pass over the convex portion in sequence and move along the first inclined surface to be dispersedly arranged on the guide.

[0006] Optionally, a second inclined surface and a third inclined surface are respectively provided on two opposite sides of the convex portion, and a lower end of the second inclined surface is connected to an upper end of the first inclined surface.

[0007] Optionally, the inclination of the first inclined surface is consistent with the inclination of the second inclined surface, and the first inclined surface and the second inclined surface are located on the same plane.

[0008] Optionally, the side surface of the carrying plate facing away from the guide member is a flat surface, and the flat surface is parallel to the moving direction of the moving component.

[0009] Optionally, a groove matching the guide member is provided on the side of the carrying plate close to the guide member.

[0010] Optionally, the sum of the vertical distance between the highest point of the protrusion and the outer wall of the guide member and the diameter of the guide member is smaller than the inner diameter of the lifting ring, and the width of the bearing plate is smaller than the inner diameter of the lifting ring.

[0011] Optionally, an outer wall of the convex portion has a transitional arc surface, and an end of the arc surface close to the first inclined surface is connected to an upper end of the first inclined surface.

[0012] Optionally, the second end of the bracket is bent to form a curved end; the moving component includes a first roller and a second roller; the first roller and the second roller are both rotatably connected to the curved end, and the first roller and the second roller are arranged in an inverted "V" shape.

[0013] Optionally, a connecting portion is provided at the first end of the supporting plate, and the connecting portion is mounted on the curved end between the first roller and the second roller.

[0014] The curtain opener and closer has the above-mentioned hanging mechanism.

[0015] Compared with the prior art, the above one or more technical solutions in the hanging mechanism provided in the embodiment of the present invention have at least one of the following technical effects:

[0016] The hooking mechanism is used in a curtain opener and closer. When in operation, the main unit of the curtain opener and closer drives the moving assembly and the bearing plate to move along the curtain guide.

[0017] When the curtains are gathered, the carrying plate moves along the guide member, and the first inclined surface of the carrying plate is inserted into the inner hole of the hanging ring, and as the carrying plate continues to move, the hanging ring is driven to move along the first inclined surface and pass over the convex portion and move to the carrying plate. Therefore, in the process of the carrying plate moving along the guide member, the multiple hanging rings on the guide member are gathered and arranged on the carrying plate in sequence, thereby achieving the folding of the curtains. It can be seen from the above that in the process of folding the curtains, the carrying plate drives the hanging ring to move to the carrying plate and carries the hanging ring and the curtain to move, reducing the sliding friction between the hanging ring and the guide member, so that the hanging mechanism drives the hanging ring and the curtain to move smoothly, and the curtain moves smoothly when it is folded.

[0018] When unfolding the curtain, multiple rings are gathered and arranged on the supporting plate, and one end of the curtain close to the end of the guide member is fixed on the guide member; the supporting plate drives the multiple rings to move along the guide member, and when each ring follows the supporting plate to move to the maximum or close to the maximum stroke, the multiple rings will sequentially and orderly cross the convex portion and move along the first inclined surface and slide onto the guide member. Therefore, in the process of the supporting plate moving along the guide member, the multiple rings on the supporting plate are dispersedly arranged on the guide member, thereby realizing unfolding of the curtain; it can be seen from the above that in the process of unfolding the curtain, the supporting plate carries the ring to move and is pulled onto the guide member when the ring moves to the maximum or close to the maximum stroke, thereby reducing the sliding friction between the ring and the guide member, so that the hanging mechanism drives the ring and the curtain to move smoothly, and the curtain moves smoothly when unfolded.

[0019] In addition, when the hanging ring is driven to move by the hanging mechanism of the present invention, not only the sliding friction between the hanging ring and the guide member is reduced, but also the power required by the main unit of the curtain opener to drive the curtain to close or open is reduced, thereby reducing the energy consumption of the main unit and facilitating energy saving.

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.

[0044] In one embodiment of the present invention, referring to Figure 1 and Figure 2 , a hanging mechanism 300 is provided for use in a curtain opener and closer.

[0045] Reference Figure 1 and Figure 2 The hanging mechanism 300 includes a connecting seat 350, a bracket 310, a moving assembly 320 and a bearing plate 400. The first end of the bracket 310 is plugged into the connecting seat 350, the second end of the bracket 310 extends out of the connecting seat 350, and the moving assembly 320 is installed at the second end of the bracket 310 and is used to be movably hung on the curtain guide 10.

[0046] Reference Figure 1 and Figure 2 The carrier plate 400 is used to carry the curtain ring 20. The carrier plate 400 is in a long strip shape, and the first end of the carrier plate 400 is connected to the second end of the bracket 310. The carrier plate 400 is parallel to the moving direction of the moving assembly 320 and is close to the guide member 10 when installed. The side of the second end of the carrier plate 400 away from the guide member is provided with a first inclined surface 420 and a convex portion 430 in sequence from the outside to the inside.

[0047] Reference Figure 1 and Figure 2 When the curtain is folded, the supporting plate 400 drives the multiple rings 20 located on the guide member 10 to move along the first inclined surface 420 in sequence and pass over the protrusion 430 to be folded and arranged on the supporting plate 400; when the curtain is unfolded, the supporting plate 400 drives the multiple rings 20 located thereon to pass over the protrusion 430 in sequence and move along the first inclined surface 420 to be dispersed and arranged on the guide member 10.

[0048] Specifically, compared with the prior art, the hooking mechanism provided by the embodiment of the present invention has one of the following technical effects:

[0049] The hooking mechanism 300 is used in a curtain opener and closeer. When in operation, the main unit 200 of the curtain opener and closeer drives the moving assembly 320 and the carrying plate 400 to move along the curtain guide 10 .

[0050] When the curtains are gathered, the carrying plate 400 moves along the guide member 10, and the first inclined surface 420 of the carrying plate 400 is inserted into the inner hole of the hanging ring 20, and the hanging ring 20 is driven to move along the first inclined surface 420 and pass over the protrusion 430 to move onto the carrying plate 400 as the carrying plate 400 continues to move. Therefore, in the process of the carrying plate 400 moving along the guide member 10, the multiple hanging rings 20 on the guide member 10 are gathered and arranged on the carrying plate 400 in sequence, thereby achieving the gathering of the curtains; it can be seen from the above that in the process of gathering the curtains, the carrying plate 400 drives the hanging ring 20 to move onto the carrying plate 400 and carries the hanging ring 20 and the curtain to move, thereby reducing the sliding friction between the hanging ring 20 and the guide member 10, so that the hanging mechanism 300 drives the hanging ring 20 and the curtain to move smoothly, and the curtain moves smoothly when gathered.

[0051] When unfolding the curtain, multiple rings 20 are gathered and arranged on the carrier plate 400, and one end of the curtain close to the end of the guide member 10 is fixed on the guide member 10; the carrier plate 400 drives the multiple rings 20 to move along the guide member 10, and when each ring 20 follows the carrier plate 400 to move to the maximum or close to the maximum stroke, the multiple rings 20 will sequentially and orderly cross the convex portion 430 and move along the first inclined surface 420 and slide onto the guide member 10. Therefore, in the process of the carrier plate 400 moving along the guide member 10, the multiple rings 20 on the carrier plate 400 are dispersedly arranged on the guide member 10, so as to realize the unfolding of the curtain; it can be seen from the above that in the process of unfolding the curtain, the carrier plate 400 carries the ring 20 to move and slides onto the guide member 10 when the ring 20 moves to the maximum or close to the maximum stroke, thereby reducing the sliding friction between the ring 20 and the guide member 10, so that the hanging mechanism 300 drives the ring 20 and the curtain to move smoothly, and the curtain moves smoothly when unfolded.

[0052] In the prior art, when unfolding the curtain, the host 200 pushes the ring 20 to move. Since the ring 20 is prone to tilt, the sliding friction between the ring 20 and the guide 10 is greater than the thrust of the host, so that the ring 20 cannot move to the maximum stroke, resulting in incomplete unfolding of the curtain. It can be understood that, in the present embodiment, the supporting plate 400 drives the hanging ring 20 to move with the supporting plate 400, and the above-mentioned convex portion 430 is provided, and the convex portion 430 has a certain blocking effect on the hanging ring 20, so that the hanging ring 20 will not cross the convex portion 430 and slide onto the guide member 10 until it moves to the maximum or close to the maximum stroke, and the movement of the hanging ring 430 makes the curtain at the corresponding position section of the hanging ring 20 also in the unfolded state, and the above-mentioned convex portion 430 can prevent the hanging ring 20 from falling from the supporting plate 400 when it does not move to the maximum or close to the maximum stroke with the supporting plate 400, and the curtain at the corresponding position section of the hanging ring 20 is in the un-expanded or partially-expanded state, and the hanging ring 20 will slide along the guide member 10 under the pull of the main unit of the curtain opener and closeer to make the curtain continue to unfold.

[0053] In summary, in the process of driving the hanging ring 20 to move through the hanging mechanism 300 of the present invention, not only the sliding friction between the hanging ring 20 and the guide member 10 is reduced, but also the power required by the main unit 200 of the curtain opener to drive the curtain to close or spread is reduced, thereby reducing the energy consumption of the main unit 200 and facilitating energy saving.

[0054] Further, refer to Figure 1 , Figure 2 and Figure 3 The second inclined surface 431 and the third inclined surface 432 are respectively disposed on opposite sides of the convex portion 430, and the lower end of the second inclined surface 431 is connected to the upper end of the first inclined surface 420. The first inclined surface 420 and the second inclined surface 431 play a guiding role. Driven by the bearing plate 400, the lifting ring 20 on the guide member 10 can easily move along the first inclined surface 420 and the second inclined surface 431 and pass over the convex portion 430 to move onto the bearing plate 400, with little resistance, smooth movement, and no jamming.

[0055] Similarly, refer to Figure 1 , Figure 2 and Figure 3 The third inclined surface 432 plays a guiding role. Driven by the supporting plate 400, the lifting ring 20 located on the supporting plate 400 can easily move along the third inclined surface 432 and pass over the protrusion 430 and move to the guide member 10 along the second inclined surface 431 and the first inclined surface 420 in turn. The resistance is small, the movement is smooth, and it will not get stuck.

[0056] Preferably, refer to Figure 1 , Figure 2 and Figure 3 The inclination of the first inclined surface 420 is consistent with the inclination of the second inclined surface 431, and the first inclined surface 420 and the second inclined surface 431 are located on the same plane, so that the resistance is smaller and the ring 20 can move more easily along the first inclined surface 420 and the second inclined surface 431 and move to the supporting plate 400.

[0057] Further, refer to Figure 1 , Figure 2 and Figure 3 The side of the bearing plate 400 away from the guide member is a flat surface 411, and the flat surface 411 is parallel to the moving direction of the moving component 320. The setting of the flat surface 411 is conducive to the movement of the lifting ring 20 on the bearing plate 400 with less resistance.

[0058] Specifically, refer to Figure 1 , Figure 2 and Figure 3The angle between the first inclined surface 420 and the moving direction of the moving assembly 320 is 5° to 20°. The angle can be 5° or 20°, more preferably 15°. The first inclined surface 420 has a small slope, which is conducive to the lifting ring 20 sliding onto the bearing plate 400 along the first inclined surface 420 and the second inclined surface 431.

[0059] Preferably, refer to Figure 1 , Figure 2 and Figure 3 The lower end of the first inclined surface 420 is close to the outer wall of the guide member 10, which is conducive to inserting the first inclined surface 420 into the inner hole of the lifting ring 20 during the movement of the supporting plate 400, so that the lifting ring 20 can be easily moved onto the supporting plate 400.

[0060] Further, refer to Figure 1 and Figure 4 A groove 412 matching the guide member 10 is provided on the side of the carrier plate 400 close to the guide member 10. The groove 412 cooperates with the guide member 10 so that the carrier plate 400 can be stably attached to the guide member 10. When the carrier plate 400 moves along the guide member 10, it will not be skewed and the movement is stable.

[0061] Further, refer to Figure 1 The sum of the vertical distance between the highest point of the protrusion 430 and the outer wall of the guide member 10 and the diameter of the guide member 10 is smaller than the inner diameter of the ring 20, and the width of the supporting plate 400 is smaller than the inner diameter of the ring 20, so that the ring 20 can pass in and out of the supporting plate 400.

[0062] Preferably, the width of the bearing plate 400 is smaller than the radius of the hanging ring 20 , thereby reducing the friction between the bearing plate 400 and the hanging ring 20 .

[0063] Specifically, the length of the supporting plate 400 is greater than or slightly greater than the length of the curtain in the folded state, so that the supporting plate 400 has a sufficient length to support the plurality of hanging rings 20 .

[0064] In another embodiment of the present invention, referring to Figure 5 The outer wall of the protrusion 430 has a transition with an arcuate surface 433, and one end of the arcuate surface 433 close to the first inclined surface 420 is connected to the upper end of the first inclined surface 420. The friction and resistance between the arcuate surface 433 and the hanging ring 20 are small, which is conducive to the hanging ring 20 moving into the above-mentioned supporting plate 400 along the first inclined surface 420 and the arcuate surface 433 in sequence, or moving out of the above-mentioned supporting plate 400 along the arcuate surface 433 and the first inclined surface 420 in sequence.

[0065] In another embodiment of the present invention, referring to Figure 1 , Figure 2 and Figure 6, the second end of the bracket 310 is bent to form a curved end 312. The curved end 312 is in an inverted "V" shape. The moving assembly 320 includes a first roller 321 and a second roller 322. The first roller 321 and the second roller 322 are both rotatably connected to the curved end 312, and the first roller 321 and the second roller 322 are arranged in an inverted "V" shape. During installation, the curtain guide member 10 is clamped between the first roller 321, the second roller 322 and the transmission wheel 220 of the host 200, and the first roller 321 and the second roller 322 move (roll) along the guide member 10 driven by the transmission wheel 220. The first roller 321 and the second roller 322 are arranged in an inverted "V" shape, so that the first roller 321 and the second roller 322 can be applied to hang on guide members 10 of different types and sizes, and have extremely high adaptability.

[0066] Preferably, refer to Figure 1 , Figure 2 and Figure 6 The angle between the axis of the first roller 321 and the axis of the second roller 322 is 90° to 110°, and the angle can be 90° or 110°, and more preferably 95°, so that the first roller 321 and the second roller 322 can be stably hung on the curtain guide 10, and can easily roll over the telescopic curtain guide 10 with a step, and will not rotate around the guide 10. At the same time, the angle is of appropriate size, and the first roller 321 and the second roller 322 will not slide out of the guide 10 during the movement of the curtain opener along the guide 10, and the structure is stable.

[0067] Further, refer to Figure 1 , Figure 2 and Figure 6 The bracket 310 also has an arc segment 314, and the two ends of the arc segment 314 are respectively connected to the curved end 312 and the vertical end 311. The curved end 312 and the arc segment 314 are roughly hook-shaped, which facilitates the first roller 321 and the second roller 322 to be hung on the guide member 10. At the same time, the arc segment 314 provides an avoidance space for the guide member 10 so that the bracket 310 will not interfere with the guide member 10.

[0068] Furthermore, in some embodiments, a protective shell (not shown) is further provided on the curved end 312, and the protective shell is in an inverted "V" shape, and two air-avoiding grooves are penetrated on the protective shell, and the first roller 321 and the second roller 322 are respectively movably accommodated in the two air-avoiding grooves, and the first roller 321 and the second roller 322 are respectively extended out of the two air-avoiding grooves on the side close to the guide member 10, so that the first roller 321 and the second roller 322 can abut against the guide member 10. In the process of the first roller 321 and the second roller 322 driving the ring or the hook to move along the guide member 10, the protective shell is provided to protect the first roller 321 and the second roller 322, so that the ring, the hook and the curtain are not easy to touch the first roller 321 and the second roller 322, thereby avoiding the phenomenon of the rollers being stuck.

[0069] Further, refer to Figure 1 , Figure 2 and Figure 6 A connecting portion 440 is provided at the first end of the supporting plate 400, and the connecting portion 440 is fixedly mounted on the curved end 312 between the first roller 321 and the second roller 322. The supporting plate 400 is located directly above the guide member 10, so that the supporting plate 400 is subjected to uniform force when carrying and driving the lifting ring 20 to move, has good movement balance, and is not easy to tilt.

[0070] It is understandable that the above-mentioned protective shell can be connected to the connecting part 440 by gluing, or some other fixed connection, detachable connection, etc., and no limitation is made here.

[0071] Specifically, refer to Figure 1 and Fig.10 The top of the connecting seat is provided with an avoidance groove 372 connected to the upper end of the mounting hole 370, and the arc segment 314 can be accommodated in the avoidance groove 372, so that the overall structure of the curtain opener and closer is more compact.

[0072] In another embodiment of the present invention, referring to Figure 1 and Figure 6 The hooking mechanism also includes a constant force spring 330. The constant force spring 330 is installed in the connecting seat 350 and can rotate around its own axis to expand and contract. The first end of the bracket 310 is connected to the constant force spring 330. The bracket 310 can move up and down relative to the connecting seat 350. That is, when the external force pulls the bracket 310 to move up, the constant force spring 330 will be stretched; after the external force is removed, the constant force spring 330 will elastically reset and contract, thereby driving the bracket 310 to move down.

[0073] When using, refer to Figure 1 and Figure 6The hook mechanism 300 is installed on the curtain opener and the constant force spring provides a force to clamp the curtain guide member 10 between the moving assembly 320 and the main unit 200 of the curtain opener and the main unit 200. The main unit 200 drives the moving assembly 320 to move along the guide member 10, thereby driving the curtain on the guide member 10 to gather or spread during the movement, thereby opening or closing the curtain.

[0074] It is understandable that the constant force spring 330 is a mature existing part, for example: constant force spring, constant force spring, constant force spring, constant force spring parts, etc. all refer to the constant force spring 330 described in the application. That is, the constant force spring 330 is a spring that can maintain constant elasticity within the corresponding stroke, that is, the elastic force of the constant force spring 330 remains constant during the expansion and contraction process. Among them, the constant force described in the application does not mean that the force size does not change at all under the ideal state, but that the change in the force size is within a very small range, which is basically close to constant, and the performance of the constant force spring 330 is related to its processing accuracy and processing technology.

[0075] For thicker or thinner guide members 10, when the bracket 310 is pulled to adjust the height position of the movable assembly 320, the force exerted by the constant force spring 330 on the movable assembly 320 remains constant, and when the hanging mechanism 300 is hung on guide members 10 of different thicknesses, the force (clamping force) exerted by the hanging mechanism 300 on the guide member 10 remains constant, and the force (clamping force) will not be too large or too small, so that the hanging mechanism 300 can be well adapted to guide members 10 of different thicknesses and has extremely high adaptability.

[0076] Reference Figure 1 and Figure 6 One end of the constant force spring 330 is spirally wound into a telescopic coil 331 , and the other end of the constant force spring 330 is a connecting end 332 .

[0077] Reference Figure 1 and Figure 6 A constant force spring installation cavity 360 is provided in the connection seat 350, and the telescopic coil 331 is horizontally installed in the constant force spring installation cavity 360. A mounting hole 370 connected to the constant force spring installation cavity 360 is vertically provided on at least one side of the top of the connection seat 350, and the first end of the bracket 310 is a vertical end 311, which is plugged into the mounting hole 370 and connected to the connection end 332, and the structure is compact.

[0078] Reference Figure 1 and Figure 6 A horizontally distributed installation shaft 361 is provided in the constant force spring installation cavity 360, and the telescopic roll 331 is rotatably sleeved on the installation shaft 361. When the constant force spring 330 performs telescopic movement, the telescopic roll 331 rotates on the installation shaft 361, and the movement is stable without shaking.

[0079] Further, refer to Figure 1and Figure 6 , there are sockets (not shown) on opposite sides of the constant force spring installation cavity 360, and the two ends of the installation shaft 361 are respectively adapted to be plugged into the two sockets, so that the installation shaft 361 is firmly installed in the constant force spring installation cavity 360, which is convenient for assembly.

[0080] Preferably, refer to Figure 1 and Figure 6 A shaft sleeve 362 is provided on the mounting shaft 361, and the telescopic roll 331 is sleeved on the shaft sleeve 362. By providing the shaft sleeve 362, when the telescopic roll 331 rotates, the friction between the telescopic roll 331 and the shaft sleeve 362 is small, so that the telescopic roll 331 rotates smoothly, and at the same time, the telescopic roll 331 is not easy to wear, thereby improving the service life of the constant force spring 330.

[0081] Reference Figure 1 and Figure 7 , a cylindrical mounting groove 365 is horizontally arranged in the constant force spring mounting cavity 360, a notch 366 is arranged on the side wall of the cylindrical mounting groove 365 near the vertical end 311, the telescopic roll 331 is adapted to be accommodated in the cylindrical mounting groove 365, and the connecting end 332 passes through the notch 366 and is connected to the vertical end 311, which is convenient for installation. At the same time, when the constant force spring 330 performs telescopic movement, the telescopic roll 331 rotates in the cylindrical mounting groove 365, and the movement is stable without shaking.

[0082] Reference Figure 6 and Figure 7 The connecting end 332 is provided with a connecting hole 332a, and the end of the vertical end 311 near the connecting end 332 is bent to form a hook 311a, and the hook 311a is hooked to the connecting hole 332a, so that the vertical end 311 and the connecting end 332 can be detachably connected, which is convenient for installation. At the same time, the above detachable setting, when the constant force spring 330 or the bracket 310 is damaged after long-term use, only the constant force spring 330 or the bracket 310 needs to be replaced, without replacing the entire thing, which is conducive to resource reuse.

[0083] Reference Figure 6 and Figure 7 A slider 340 is provided in the middle of the vertical end 311, and the slider 340 is slidably connected to the mounting hole 370. By providing the slider 340, the bracket 310 can move up and down along the mounting hole 370 smoothly, and the movement is stable and not easy to be skewed.

[0084] Further, refer to Figure 6 and Figure 7 , two opposite sides of the mounting hole 370 are vertically provided with slide grooves 371, and two opposite sides of the slider 340 are provided with sliding parts 341.

[0085] Preferably, refer to Fig.12 and Fig.13 , the straight line A formed by the projection of the curved end 312 on the horizontal plane is arranged obliquely with the axis B of the guide member 10, so that the first roller 321 and the second roller 322 installed on the curved end 312 are arranged obliquely with the axis B of the guide member 10. With the above arrangement, when the first roller 321 and the second roller 322 move along the guide member 10, the first roller 321 and the second roller 322 will roll over the guide member 10 one after the other or one after the other, which is conducive to smoothly passing the stepped guide member 10 (telescopic rod) without getting stuck.

[0086] Specifically, refer to Fig.12 and Fig.13 One end of the slider 340 is provided with an inclined groove 342 along its axial direction (i.e. the direction in which the slider 340 moves along the slide groove 121), and the inclined groove 342 is arranged obliquely with respect to the axis B of the guide member 10. The vertical end 311 passes through the inclined groove 342, and the middle part of the vertical end 311 is provided with an inclined block 311b adapted to be snapped into the inclined groove 342, so that the bracket 310 and the axis B of the guide member 10 are arranged obliquely, so that the straight line A formed by the projection of the curved end 312 on the horizontal plane and the axis B of the guide member 10 are arranged obliquely, and the connection is stable and easy to assemble.

[0090] Reference Fig. 9 and Fig.11 There is friction between the transmission wheel 220 and the guide member 10. Under the drive of the driving member 210, the transmission wheel 220 can move along the guide member 10. The host 200 drives the hanging mechanism 300 to move along the guide member 10 and pushes the curtain 110 installed on the guide member 10 to realize the electric opening and closing of the curtain 110. There is no need to open and close the curtain manually, and the operation is convenient.

[0091] Reference Fig. 9 and Fig.11 The driving member 210 is a motor, and the driving member 210 is coaxially arranged with the transmission wheel 220, so as to facilitate the smooth movement of the transmission wheel 220 and make full use of the space. The motor is fixed to the inner cavity 101 through the mounting seat 211, and the transmission wheel 220 is a hollow wheel. The transmission wheel 220 is sleeved on the motor and is rotatably connected to the motor through the transmission wheel bearing 221. The rotating shaft of the motor is connected to one end of the transmission wheel 220 and drives the transmission wheel 220 to rotate.

[0092] Furthermore, in other embodiments, the driving member 210 may also be configured as a rotary cylinder.

[0093] Among them, refer to Fig. 9 and Fig.10 , two opposite sides of the base 100 are provided with a hooking mechanism 300, but the number is not limited to the above. Two hooking mechanisms 300 are provided on the left and right sides of the base 100, so that the base 100 has a substantially left-right symmetrical structure, which is conducive to the stable operation of the host 200, reduces the shaking caused by the unstable center of gravity, and stabilizes the structure.

[0094] In other embodiments, the hanging mechanism 300 may also be connected to one side of the base 100 .

[0095] Further, refer to Fig. 9 and Fig.10 , the base 100 is provided with a receiving groove 151 on both sides opposite to each other, and a clamping groove 152 is recessed on both sides opposite to each other of the receiving groove 151. Buckles 381 are convexly provided on both sides opposite to each other of the connecting seat 350, and the connecting seat 350 is partially inserted into the receiving groove 151, and two buckles 381 are respectively correspondingly engaged with two clamping grooves 152, so that the connecting seat 350 and the base 100 are detachably fixedly connected. The connecting seat 350 and the base 100 are arranged in the above-mentioned detachable manner, which is convenient for assembling the curtain opener and closer on the one hand, and on the other hand, when the connecting seat 350 or the hanging mechanism 300 on the connecting seat 350 is damaged after long-term use, only the connecting seat 350 or the hanging mechanism 300 needs to be replaced, and there is no need to replace the base 100 as a whole, which is conducive to resource reuse.

[0096] Further, refer to Figure 8 and Fig.10The two opposite sides of the connection seat 350 are both provided with a key installation groove 351, and the key installation groove 351 is slidably connected with a key 380, and the key 380 can move along the depth direction of the key installation groove 351. Specifically, the key 380 is adapted to the key installation groove 351, and the key 380 can stably move along the key installation groove 351 under the push of an external force.

[0097] Reference Figure 8 and Fig.10 A spring 390 is provided between the bottom of the button installation slot 351 and the button 380, and a buckle 381 is provided at the end of the button 380 away from the spring 390. The buckle 381 is exposed outside the button installation slot 351. The spring 390 elastically pushes the buckle 381 to be clamped in the clamping slot 152, so that the connecting seat 350 and the base 100 can be detachably clamped and firmly clamped. When disassembling, an external force presses the button 380 and compresses the spring 390, driving the buckle 381 away from the clamping slot 152 and disengaging from the clamping slot 152, that is, the connecting seat 350 is removed from the base 100, and the operation is convenient.
