Description

Technical Field

[0001] The utility model relates to the field of smart home, in particular to a dream curtain. Background Art

[0002] Compared with ordinary electric opening and closing curtains, the curtain track of the dream curtain needs to additionally set the installation position of the dimming rod. In order to prevent the dimming rod from slipping out of the curtain chute at the bottom of the curtain track, on the one hand, it is necessary to reduce the width of the curtain chute, and on the other hand, it is also necessary to set a flexible support member above the curtain chute to adjust the width of the curtain chute.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0051] First Embodiment:

[0052] An embodiment of the present utility model provides a dream curtain, which includes a curtain track body and a light-adjusting rod disposed inside the curtain track body. The curtain track body includes a curtain sliding groove disposed at the bottom. A stop edge is formed at a position corresponding to the light-adjusting rod on the curtain track body, and the stop edge is used to prevent the light-adjusting rod from slipping out of the curtain sliding groove. The dream curtain further includes a curtain bead. The light-adjusting rod is disposed on the curtain bead. The curtain bead includes a light-adjusting rod fixing part and a curtain hanging part fixing part. An avoidance groove is further formed between the light-adjusting rod fixing part and the curtain hanging part fixing part of the curtain bead, and the position of the avoidance groove corresponds to that of the stop edge.

[0053] In this embodiment, the avoidance groove is a through groove, and the through groove at least partially penetrates the front end face and the rear end face of the curtain bead. The bead housing includes an upper housing located above the through groove and a lower housing located below the through groove. A stop edge is formed at a position corresponding to the through groove on the curtain track body. The stop edge is located above the curtain sliding groove, and the position height of the stop edge corresponds to the position height of the light-adjusting rod, and the stop edge extends in the length direction of the curtain track body.

[0054] In this embodiment, the stop edge is not directly connected to the notch of the curtain sliding groove. When installing the curtain bead, the method of first installing the lower housing of the bead and the bead gear assembly and then installing the upper housing of the bead can be adopted. After the upper housing and the lower housing are installed, they are positioned on the stop edge through the through groove, and at the same time, the curtain bead can slide relative to the length direction of the curtain track body.

[0055] In the embodiment of the present utility model, a stop edge is formed at the corresponding position of the curtain rail body with respect to the light-adjusting rod. The stop edge is used to prevent the light-adjusting rod from slipping out of the curtain chute. At the same time, the bead housing is divided into a light-adjusting rod fixing part and a curtain hanging part fixing part. An avoidance groove is also formed between the light-adjusting rod fixing part and the curtain hanging part of the bead housing. This facilitates the stop edge of the curtain rail body to extend into the avoidance groove to limit the light-adjusting rod and prevent the light-adjusting rod from slipping out of the curtain chute. When processing the curtain rail body, it is not necessary to deliberately reduce the width of the curtain chute, nor is it necessary to use a flexible support member to reduce the width of the curtain chute, greatly improving the processing efficiency of the curtain rail body, reducing the production process, and saving materials and assembly costs.

[0056] Second Embodiment:

[0057] An embodiment of the present utility model provides a dream curtain, including a curtain rail body and a light-adjusting rod disposed within the curtain rail body. The curtain rail body includes a curtain chute disposed at the bottom. A stop edge is formed at the corresponding position of the curtain rail body with respect to the light-adjusting rod. The stop edge is used to prevent the light-adjusting rod from slipping out of the curtain chute. The curtain rail body includes a curtain chute disposed at the bottom. Multiple stop edges are provided at the corresponding position of the curtain chute of the curtain rail body. The stop edge is located above one side of the notch of the curtain chute.

[0058] Specifically, the stop edge extends from the notch of the curtain chute to above the notch. In the solution of this embodiment, the stop edge can be integrally formed with the curtain chute, or the stop edge can be installed on the curtain chute through an assembly structure. It can be foreseen that the assembly structure includes, but is not limited to, slot fixing, snap fixing, screw fixing, clamping mechanism fixing, mortise and tenon fixing, or welding fixing, etc.

[0059] As a specific solution rather than a limitation, the curtain rail body of this embodiment includes a rail profile. The rail profile forms the curtain chute at the bottom. A first space for setting the light-adjusting rod fixing part of the curtain bead is formed inside the rail profile on one side of the curtain chute. A second space for setting the curtain hanging part fixing part of the curtain bead is formed inside the rail profile on the other side of the curtain chute. The stop edge is disposed between the first space and the curtain chute.

[0060] In this embodiment, the stop edge is disposed perpendicular to the notch surface of the curtain chute, and the multiple stop edges are spaced apart in the length direction of the curtain chute.

[0061] As a specific solution rather than a limitation, the shapes and heights of the above-mentioned multiple stop edges can be different. When all the running beads of the dream curtain are retracted to both sides of the curtain track body, since the part of the light-dimming rod in the middle of the curtain track body is deformed the most under the action of gravity, the light-dimming rod is most likely to come out in the middle of the curtain track body. Therefore, the height of the stop edge located in the middle of the curtain track body is the highest to facilitate fixing the middle part of the light-dimming rod.

[0062] As a preferred solution, when the stop edge can be disassembled and assembled relative to the curtain track body through an assembly structure, the manufacturer or user can select the installation quantity of the stop edge and the installation position of the stop edge relative to the curtain track body according to their own needs, so as to make the fixing of the stop edge to the light-dimming rod more flexible and convenient while improving the processing efficiency of the curtain track body.

[0063] Third Embodiment:

[0064] Please refer to Figures 1 to 13 As shown in the figure, the embodiment of the present utility model provides a dream curtain, including a curtain track body and a light-dimming rod arranged in the curtain track body. The curtain track body includes a curtain sliding groove arranged at the bottom. A stop edge 91 is formed at a corresponding position of the curtain track body with respect to the light-dimming rod. The stop edge 91 is used to prevent the light-dimming rod from coming out of the curtain sliding groove. The dream curtain further includes curtain running beads movably arranged in the curtain track body. The curtain running beads include a running bead housing 1 and a curtain hanging member 4 arranged on the running bead housing 1. The running bead housing 1 includes a light-dimming rod fixing part 12 and a curtain hanging member fixing part 13. An avoidance groove 11 is further formed between the light-dimming rod fixing part 12 and the curtain hanging member fixing part 13 of the running bead housing 1. The position of the avoidance groove 11 corresponds to the position of the stop edge 91.

[0065] The running bead gear assembly of the traditional curtain running beads usually adopts a horizontally arranged power transmission mechanism. By converting the rotational kinetic energy of the light-dimming rod in the vertical plane into the rotational kinetic energy of the curtain hanging member in the horizontal plane, the power is transmitted, thereby changing the angle of the curtain blade. However, the running bead housing corresponding to the above-mentioned running bead gear assembly is designed flat, without space for opening the avoidance groove.

[0066] Based on this, a curtain running bead gear assembly is further arranged inside the running bead housing 1 in the embodiment of the present utility model, including a vertical active transmission mechanism, a vertical passive transmission mechanism, and a horizontal transmission mechanism connected between the vertical active transmission mechanism and the vertical passive transmission mechanism. The vertical passive transmission mechanism is linked with the vertical active transmission mechanism through the horizontal transmission mechanism. An avoidance space 2 is formed between the vertical active transmission mechanism and the vertical passive transmission mechanism. The position of the avoidance space 2 corresponds to the position of the avoidance groove 11.

[0067] In an embodiment of the present utility model, a curtain bead gear assembly is provided, which includes a vertical active transmission mechanism, a vertical passive transmission mechanism, and a horizontal transmission mechanism connected between the vertical active transmission mechanism and the vertical passive transmission mechanism. The vertical passive transmission mechanism is linked with the vertical active transmission mechanism through the horizontal transmission mechanism. This changes the horizontally arranged power transmission mechanism of the traditional gear assembly into a "vertical + horizontal + vertical" power transmission mechanism, facilitating the formation of an avoidance space between the vertical active transmission mechanism and the vertical passive transmission mechanism. When an avoidance groove is formed at the position of the bead housing corresponding to the avoidance space, it is convenient for the stop edge of the curtain track body to extend into for limiting the light control rod, preventing the light control rod from disengaging from the curtain chute. By setting the bead gear assembly as a "vertical + horizontal + vertical" power transmission mechanism in the embodiment of the present utility model, a space can be reserved at the avoidance space for the stop edge of the curtain track body to extend into, so as to prevent the light control rod from disengaging from the curtain chute.

[0068] As a specific solution rather than a limitation, the avoidance space 2 is formed below the horizontal transmission mechanism. The avoidance space 2 at least partially penetrates the front end face and the rear end face of the curtain bead gear assembly.

[0069] As a preferred solution rather than a limitation, the opening of the avoidance space 2 is located at the bottom of the bead gear assembly, and the avoidance space 2 is used for the stop edge 91 of the curtain track body to extend into from bottom to top. Different from the above first embodiment, the curtain chute of the curtain track body corresponding to this embodiment is directly connected to the stop edge 91, and the stop edge extends upward from the curtain chute to the corresponding position of the light control rod.

[0070] The vertical active transmission mechanism is driven by the light control rod 3 of the fantasy curtain, and the vertical passive transmission mechanism is used to drive the curtain hanging member 4. As a specific solution rather than a limitation, the vertical active transmission mechanism in this embodiment is used to transmit the power of the light control rod 3 from bottom to top to the horizontal transmission mechanism, and the vertical passive transmission mechanism is used to transmit the power of the horizontal transmission mechanism from top to bottom to the curtain hanging member 4.

The horizontal transmission mechanism includes the common adapter part and a first bevel gear body 6 linked with the common adapter part. The vertical passive transmission mechanism includes a second bevel gear body 7 linked with the first bevel gear body 6.

[0072] Among them, the dimming rod socket 5 includes a ball-bearing rotating shaft 51 and a ball-bearing worm 52. The ball-bearing rotating shaft 51 is provided for the dimming rod 3 to pass through and be sleeved, and the ball-bearing worm 52 is sleeved around the ball-bearing rotating shaft 51. In this embodiment, the shape of the inner wall surface of the ball-bearing rotating shaft 51 corresponds to the shape of the peripheral wall of the dimming rod 3, so that the ball-bearing rotating shaft 51 can rotate synchronously with the dimming rod 3. A positioning convex rib 511 is formed on the outer wall surface of the ball-bearing rotating shaft 51, and a positioning groove 521 is formed on the inner wall surface of the ball-bearing worm 52 at a position corresponding to the positioning convex rib 511. The positioning convex rib 511 cooperates with the positioning groove 521 at a corresponding angle to achieve circumferential fixation of the ball-bearing rotating shaft 51 and the ball-bearing worm 52 at a corresponding angle.

[0073] In the solution of the present utility model, the first bevel gear body and the common adapter of the above-mentioned lateral transmission mechanism are integrally formed, or the first bevel gear body and the common adapter of the lateral transmission mechanism are separately assembled. Specifically in this embodiment, the first bevel gear body and the common adapter are separately assembled.

[0074] As a specific solution rather than a limitation, a worm helical tooth 522 is formed on the outer wall surface of the ball-bearing worm 52. The common adapter includes a ball-bearing worm wheel 8, and a worm wheel tooth 81 that cooperates with the worm helical tooth 522 is formed on the outer wall surface of the ball-bearing worm wheel 8. Preferably, the ball-bearing worm wheel 8 of this embodiment further includes a limiting rib 82 that circumferentially penetrates through a plurality of worm wheel teeth 81, and the limiting rib 82 is at least used to limit the rotation angle of the ball-bearing worm 52.

[0075] As a specific solution rather than a limitation, the ball-bearing worm wheel 8 is horizontally arranged, and a shaft hole 83 is formed in the middle of the ball-bearing worm wheel 8. The first bevel gear body 6 is horizontally arranged, including a first bevel gear 61, and further includes a positioning column 62 that horizontally extends along the corresponding direction of the shaft hole 83 on the first bevel gear 61. The positioning column 62 is used to cooperate with the shaft hole 83. The first bevel gear 61 of this embodiment is arranged in a vertical plane, and the shapes of the positioning column 62 and the shaft hole 83 correspond to each other to achieve circumferential fixation of the ball-bearing worm wheel 8 and the first bevel gear body 6.

[0076] Furthermore, the second bevel gear body 7 is vertically arranged. The second bevel gear body 7 includes a second bevel gear 71 arranged on a horizontal plane. The second bevel gear 71 is used to mesh with the first bevel gear 61. The second bevel gear body 7 further includes a shaft sleeve 72 that extends downward from the second bevel gear 71. The shaft sleeve 72 is used to install the curtain hanging member 4.

[0077] In this embodiment, the bushing 72 includes a slot 721 formed in the middle and a positioning hole 722 formed in the bushing 72. The curtain hanging member 4 includes a hook 41 at the bottom and a clamping portion 42 above the hook 41. The clamping portion 42 is columnar and has a buckle 421 formed at a position corresponding to the positioning hole 722. When the columnar clamping portion 42 extends into the slot 721 of the bushing 72 and abuts against the bottom of the slot 721, the buckle 421 extends into the positioning hole 722 to fix the curtain hanging member 4 relative to the bushing 72.

[0078] It should be noted that those skilled in the art can also split the first bevel gear body 6 and the second bevel gear body 7 into multiple independent parts according to needs, or improve or evolve the specific structures of the first bevel gear body 6 and the second bevel gear body 7. Equivalent alternative solutions based on the concept of the present utility model all fall within the protection scope of the present utility model.

[0079] In addition, in order to improve the assembly convenience of the curtain bead, those skilled in the art can also fix the second bevel gear body 7 and the curtain hanging member 4 through a fixing structure according to needs, or integrally form the second bevel gear body 7 and the curtain hanging member 4, or improve or evolve the specific structure at the connection of the second bevel gear body 7 and the curtain hanging member 4. Equivalent alternative solutions based on the concept of the present utility model all fall within the protection scope of the present utility model.

[0080] As a preferred solution rather than a limitation, in order to improve the assembly convenience of the curtain bead and make the matching angles of the gear assemblies of each curtain bead consistent after assembly, so as to achieve the purpose of consistent setting angles of each curtain hanging member and each curtain panel in the later stage, the first bevel gear body 6 of this embodiment is provided with a first standard alignment structure, and the second bevel gear body 7 is provided with a second standard alignment structure.

The first standard alignment structure is a positioning groove provided on a positioning post, and the second standard alignment structure is a positioning flange provided on the inner wall surface of a bushing. Moreover, the opening of the positioning groove faces downward, which is the same as the opening direction of the bushing. This allows for convenient use of the same jig to uniformly adjust the matching angles of the parts of the gear assembly from below the ball bearing housing, enabling the matching angles of the parts of each gear assembly to be consistent, achieving the purpose of consistent setting angles for each curtain hanging member and each curtain panel in the later stage, improving the assembly convenience of the curtain ball bearing, and saving labor costs.

[0088] As a specific solution rather than a limitation, the distance piece positioning structure is arranged on the side surface of the ball bearing housing close to the curtain hanging member fixing part 13, and the retaining edges 15 enclose part of the notch of the installation groove 14. In this embodiment, the installation groove 14 is provided on the side surface of the ball bearing housing 1, and at the same time, two retaining edges 15 are arranged opposite to each other in the vertical direction, so that the distance piece 101 is fixed on the ball bearing housing 1 in an upright manner, facilitating the turning of the curtain track and expanding the application scenario of the dream curtain in this embodiment.

[0089] As a preferred solution rather than a limitation, a placement surface 16 is formed at the corresponding position of the ball housing 1 with respect to the positioning post 62, and the shape of the placement surface 16 corresponds to the shape of the peripheral wall of the positioning post 62. In this embodiment, the positioning post 62 is a hexagonal prism, and for the convenience of the positioning post 62 to rotate on the placement surface 16, the placement surface 16 of this embodiment is a circular curved surface. The placement surface 16 is used to provide a supporting force for the positioning post 62 to assist in fixing the first bevel gear body 6. On the one hand, it improves the installation convenience of the curtain ball, and on the other hand, it also ensures the structural stability of the internal gear assembly of the curtain ball.

[0090] As a preferred solution rather than a limitation, wing plates 17 extend upward on both sides of the placement surface 16. The top ends of the wing plates 17 are located above the positioning post 62, and a notch is formed between the two wing plates 17 for the positioning post 62 to be placed from top to bottom. The wing plates 17 assist in fixing the positioning post 62 on both sides. On the one hand, it improves the installation convenience of the curtain ball, and on the other hand, it also ensures the structural stability of the internal gear assembly of the curtain ball.

[0091] Corresponding to the above improvement, the ball housing 1 of this embodiment further includes an integrally formed top cover 18. An upright wall 181 is formed at the bottom of the top cover 18 at the corresponding position of the notch, and the width of the upright wall 181 corresponds to the width of the notch. The upright wall 181 is used to close the notch between the wing plates 17 and plays a role in assisting in fixing the first bevel gear body 6.

[0092] As a preferred solution rather than a limitation, an annular upright wall 182 is further formed at the bottom of the top cover 18. The second bevel gear body 7 further includes a column 74 extending upward from the second bevel gear 71, and the position of the annular upright wall 182 corresponds to the position of the column 74. The annular upright wall 182 is used for the column 74 to extend into and assist in fixing the second bevel gear body 7, ensuring the structural stability of the internal gear assembly of the curtain ball.

[0093] As a preferred solution rather than a limitation, a bayonet 183 is further formed at the corresponding position of the top cover 18 with respect to the ball turbine 8, and the bayonet 183 is used to assist in fixing the outer end of the ball turbine 8.

[0094] Corresponding to the above positioning groove 63 for uniformly adjusting the matching angle of the gear assembly of the curtain ball, a through hole 19 is opened in the ball housing 1 at the corresponding position of the positioning groove 63. Corresponding to the above positioning flange 73 for uniformly adjusting the matching angle of the gear assembly of the curtain ball, a counterpoint port 131 is opened in the ball housing at the corresponding position of the positioning protrusion. So that after the ball gear assembly is placed in the ball housing 1, the matching angles of the various parts of the gear assembly can be adjusted to achieve the purpose of consistent setting angles of the later curtain hanging parts and each curtain panel, further improving the assembly convenience of the curtain ball and saving labor costs.

[0095] As a preferred solution but not a limitation, the roller housing is formed with a first sliding contact 132 at the bottom of the curtain hanging fixing part 13, and the roller housing 1 is formed with a second sliding contact 121 at the bottom of the dimming rod fixing part 12. Specifically, the first sliding contact 132 is located at the bottom of the bottom plate below the distance piece positioning structure. The first sliding contact 132 and the second sliding contact 121 are respectively located on both sides of the curtain roller, and are used to contact the inner wall surface of the curtain track body, which can replace the curtain roller wheel to reduce the friction of the curtain roller when sliding in the curtain track body, simplifying the curtain roller structure while ensuring the user experience.

[0096] As a preferred solution but not a limitation, the stop edge 91 is located between the vertical active transmission mechanism and the curtain slide 92. Since the active transmission mechanism is fixed to the dimming rod 3, the above structure allows the dimming rod to be confined to the inner space of the curtain slide relative to the stop edge. When the height of the stop edge corresponds to the height of the dimming rod, the dimming rod can be effectively prevented from crossing the stop edge and falling from the curtain slide.

[0097] As a preferred solution but not a limitation, the curtain track body includes a track profile 9, the track profile 9 forms the curtain slide groove 92 at the bottom, and the track profile 9 extends upward from the curtain slide groove 92 at a corresponding position of the avoidance space to form the stop edge 91.

[0098] The embodiment of the utility model has the advantages of simple structure and convenient manufacturing by directly forming a stop edge on the track profile, compared with setting the stop edge on the curtain track body. As a preferred solution but not a limitation, the track profile can also be formed with a sliding track on the dimming rod fixing part of the curtain roller. The sliding track protrudes from the surface of the track profile and contacts with the bottom of the dimming rod fixing part, so as to reduce the sliding friction of the curtain roller.

[0099] A first space 93 is formed inside the track profile 9 on one side of the curtain slide groove 92 for setting the dimming rod fixing part 13 of the curtain roller, and a second space 94 is formed inside the track profile 9 on the other side of the curtain slide groove 92 for setting the curtain hanger fixing part 12 of the curtain roller, and the stop edge 91 is set between the first space 93 and the curtain slide groove 92.

[0100] As a preferred solution but not a limitation, the track profile 9 extends upward from a side of the curtain slide corresponding to the first space 93 to form the stop edge 91 .

[0101] The stop edge 91 includes a top end. In some alternative solutions covered by the scope of the utility model protection, the height of the top end can be lower than the central height of the light-dimming rod 3. When the height of the top end of the stop edge 91 is at the same level as the lowest end height of the light-dimming rod 3, due to the natural deformation of the light-dimming rod 3 under the action of gravity, the light-dimming rod 3 will present a natural downward-bending arc, so that the top end of the stop edge 91 at the same level as the lowest end height of the light-dimming rod 3 can limit part of the downward-bending light-dimming rod 3, which can play a certain role in preventing the light-dimming rod 3 from falling out of the curtain chute. Preferably, in this embodiment, the height of the top end is not lower than the central height of the light-dimming rod 3. The height of the top end of the stop edge 91 not being lower than the central height of the light-dimming rod 3 enables the stop edge 91 to effectively limit the light-dimming rod 3, so as to more effectively prevent the light-dimming rod 3 from disengaging from the curtain chute 92.

[0102] In this embodiment, the top end of the stop edge 91 is arranged closer to the middle of the curtain chute 92 relative to the bottom end of the stop edge 91. Preferably, the stop edge 91 includes a bent portion 912, and at least the bent portion 912 corresponds to the position of part of the side surface of the light-dimming rod fixing portion 13 of the adjacent curtain bead.

[0103] As a specific example rather than a limitation of the stop edge, the stop edge 91 successively forms a first vertical surface 911, a bent portion 912, and a second vertical surface 913 in the upward direction. The first vertical surface 911 and the second vertical surface 913 can be vertical surfaces or inclined surfaces. In this embodiment, the first vertical surface 911 and the second vertical surface 913 are vertical surfaces.

[0104] As a preferred solution rather than a limitation, the shape of the second vertical surface 913 corresponds to the shape of part of the side surface of the light-dimming rod fixing portion 13 of the adjacent curtain bead. In this embodiment, the bent portion 912 and the second vertical surface 913 corresponding to the side surface shape of the light-dimming rod fixing portion 13 can, on the one hand, play a role in assisting in fixing the curtain bead, preventing the curtain bead from vibrating laterally in the track profile 9, improving the structural stability, and on the other hand, can effectively reduce the lateral dimension of the curtain track profile 9, reduce the volume occupied by the curtain bead, and enhance the user experience.

[0105] In this embodiment, the stop edge 91 and the track profile 9 are integrally formed. The stop edge 91 extends in the length direction of the track profile 9, and the length of the stop edge 91 corresponds to the length of the track profile 9. By directly integrally forming the stop edge 91 with the track profile 9 in the embodiment of the present utility model, while ensuring the fixing stability of the light-dimming rod 3, it has the advantages of simple structure and convenient manufacturing compared with setting the stop edge 91 on the curtain track body, further improving the processing efficiency of the curtain track body.

[0106] As a specific solution rather than a limitation, a belt circulation cavity 95 for a fantasy curtain driven by a belt is further formed above the first space 93 and the second space 94 of the track profile 9.

[0107] As a preferred solution rather than a limitation, light-passing holes 104 are formed on the front, above, and / or below of the curtain track body. A light-transmitting cover 102 is provided at the light-passing holes of the curtain track body, and a light source 103 is further formed inside the light-passing holes of the curtain track body.

[0108] Specifically, in this embodiment, the light source 131 is arranged on the back of the belt circulation cavity 95 located on the front. The light source 103 and the light-transmitting cover 102 extend in the length direction of the curtain track body to horizontally create a light and shadow effect penetrating the curtain track body.

[0109] Fourth Embodiment:

[0110] When the curtain bead is installed on the curtain track, in view of the fact that when dimming is achieved, during the rotation of the dimming rod, a driving force will be generated to drive the overall left and right shaking of the curtain bead, resulting in noise. Please refer to Figure 14 As shown, the difference between the embodiment of the present utility model and the above-mentioned third embodiment is that a height compensation member is further provided on the bead housing 1 of the curtain bead, and the height compensation member is located at the top of the bead housing 1. The height compensation member can be a protruding member 184 provided on the top cover 18, and the shape of the protruding member 184 includes a cylindrical shape, a prismatic shape, a hemispherical shape, a frustum shape, a square frustum shape, or a combination of two / several of the above shapes.

[0111] As a specific solution rather than a limitation, the protruding member 184 in this embodiment can adopt a cylindrical bottom and a hemispherical top. The number of the protruding members 184 can be two, which are respectively arranged at both ends of the top cover 18 to ensure the dynamic stability of the curtain bead when working in the curtain track body. The hemispherical top can be in contact with the corresponding inner wall surface of the curtain track body, or a certain gap can be reserved. This embodiment does not make any restrictions.

[0112] As a preferred solution rather than a limitation, the above-mentioned protruding member 184 can be integrally formed with the top cover 18.

[0113] In this embodiment, by providing a bead housing with a height compensation member, the longitudinal gap between the curtain bead and the corresponding cavity of the curtain track is eliminated or reduced, so that when the curtain bead is driven by the dimming rod in the curtain track body, the vertical displacement of the curtain bead can be effectively controlled, the movement space of the curtain bead perpendicular to the dimming rod can be restricted, and further, the left and right shaking of the curtain bead can be effectively avoided, so as to improve the dynamic stability of the curtain bead, which is beneficial to further reducing the noise generated during the operation of the curtain and improving the user experience.

[0114] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
