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 circumstances.

[0046] First Embodiment:

[0047] The embodiments of the present utility model provide a curtain track structure, including a curtain track body. The curtain track body includes a curtain sliding groove provided at the bottom, and a stop edge is formed at a corresponding position of the curtain track body with respect to the curtain sliding groove. The stop edge is located above one side of the notch of the curtain sliding groove.

[0048] As a specific solution rather than a limitation, the stop edge is located above the curtain sliding groove. The position height of the stop edge corresponds to the position height of the light-adjusting rod inside the curtain track body. The stop edge extends in the length direction of the curtain track body, and the stop edge is not directly connected to the notch of the curtain sliding groove. Both ends of the stop edge in the length direction are respectively connected to the two side surfaces of the curtain track body.

[0049] Corresponding to the above curtain track structure, the bead housing of the dream curtain includes a light-adjusting rod fixing part and a curtain hanging part fixing part, and an avoidance groove is further formed between the light-adjusting rod fixing part and the curtain hanging part fixing part of the bead housing.

[0050] The avoidance groove is a through groove. An upper housing located above the through groove and a lower housing located below the through groove, and the stop edge is formed at a corresponding position of the curtain track body with respect to the through groove.

[0051] In this embodiment, since the stop edge is not directly connected to the notch of the curtain chute, when installing the curtain bead, the bead lower housing and the bead gear assembly can be installed first, and then the bead upper housing can be installed. 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.

[0052] The embodiment of the utility model provides a curtain track structure, including a curtain track body, the curtain track body includes a curtain chute arranged at the bottom, the curtain track body is provided with at least one stop edge at a corresponding position of the curtain chute, and the stop edge is located above one side of the notch of the curtain chute. The stop edge of the curtain track body can limit the light-dimming rod to prevent the light-dimming rod from slipping out of the curtain chute. When processing the curtain track 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 further limit the width of the curtain chute, which greatly improves the processing efficiency of the curtain track body, reduces the production process, and saves materials and assembly costs.

[0053] Second embodiment:

[0054] The embodiment of the utility model provides a curtain track structure, including a curtain track body, the curtain track body includes a curtain chute arranged at the bottom, the curtain track body is provided with multiple stop edges at a corresponding position of the curtain chute, and the stop edge is located above one side of the notch of the curtain chute.

[0055] 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, tenon and mortise fixing or welding fixing, etc.

[0056] As a specific solution rather than a limitation, the curtain track body of this embodiment includes a track profile, and the track profile forms the curtain chute at the bottom. A first space for setting the light-dimming rod fixing part of the curtain bead is formed inside the track profile on one side of the curtain chute, and a second space for setting the curtain hanging part fixing part of the curtain bead is formed inside the track profile on the other side of the curtain chute, and the stop edge is arranged between the first space and the curtain chute.

[0057] In this embodiment, the stop edge is arranged 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.

[0058] 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 deforms 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.

[0059] 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.

[0060] Third Embodiment:

[0061] Please refer to Figures 1 to 3 As shown, the embodiment of the present utility model provides a curtain track structure applied to a dream curtain, including a curtain track body. The curtain track body includes a curtain sliding groove 92 provided at the bottom. The curtain track body forms a stop edge 91 at a corresponding position of the curtain sliding groove 92. The stop edge 91 is located above one side of the notch of the curtain sliding groove 92.

[0062] In this embodiment, the stop edge 91 extends from the notch of the curtain sliding groove 92 to above the notch.

[0063] As a preferred solution rather than a limitation, the curtain track body includes a track profile 9. The track profile 9 forms the curtain sliding groove 92 at the bottom. A first space 93 for setting the light-dimming rod fixing part 13 of the curtain running bead is formed inside the track profile 9 on one side of the curtain sliding groove 92, and a second space 94 for setting the curtain hanging part fixing part 12 of the curtain running bead is formed inside the track profile 9 on the other side of the curtain sliding groove 92. The stop edge 91 is arranged between the first space 93 and the curtain sliding groove 92.

[0064] As a preferred solution rather than a limitation, the track profile 9 extends upward from the side corresponding to the first space 93 of the curtain sliding groove to form the stop edge 91.

[0065] 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 level with the bottommost 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-curved arc, so that the top end of the stop edge 91 that is level with the bottommost height of the light-dimming rod 3 can limit part of the downward-curved 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.

[0066] 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 bending portion 912, and at least the bending portion 912 corresponds to the position of a part of the side surface of the light-dimming rod fixing portion 13 of the adjacent curtain bead.

[0067] As a specific example rather than a limitation of the stop edge, the stop edge 91 is successively formed with a first vertical surface 911, a bending 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.

[0068] As a preferred solution rather than a limitation, the shape of the second vertical surface 913 corresponds to the shape of a part of the side surface of the light-dimming rod fixing portion 13 of the adjacent curtain bead. In this embodiment, the bending 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 horizontally 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 dream curtain, and enhance the user experience.

[0069] 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.

[0070] As a specific solution rather than a limitation, a belt circulation cavity 95 for a dream curtain driven by a belt is further formed above the first space 93 and the second space 94 of the track profile 9.

[0071] Fourth Embodiment:

[0072] In the embodiment of the present utility model, a curtain track structure is provided. Different from the above-mentioned third embodiment, the stop edge extends along the middle direction of the curtain chute in the upward direction.

[0073] The stop edge of this embodiment gradually approaches the middle of the curtain chute throughout the entire height stroke in the upward direction, so that the width of the first space gradually increases in the upward direction, making the shape selection of the curtain running beads more diverse and improving the adaptability to different shapes of the curtain running beads.

[0074] Fifth Embodiment:

[0075] Please refer to Figures 1 to 13 As shown, the embodiment of the present utility model provides a dream curtain, including curtain running beads and a light-adjusting rod 3 provided on the curtain running beads, and further including the curtain track structure described in the above-mentioned third embodiment.

[0076] The curtain running beads include a running bead housing 1 and a curtain hanging member 4 provided on the running bead housing 1. The running bead housing 1 includes a light-adjusting rod fixing portion 12 and a curtain hanging member fixing portion 13, and an avoidance groove 11 is further formed between the light-adjusting rod fixing portion 12 and the curtain hanging member fixing portion 13 of the running bead housing 1.

[0077] The running bead gear assembly of the traditional dream curtain usually adopts a horizontally arranged power transmission mechanism. By converting the rotational kinetic energy of the light-adjusting rod in the vertical plane into the rotational kinetic energy of the curtain hanging member in the horizontal plane, the power is transmitted to change the angle of the curtain blades. However, the running bead housing corresponding to the above-mentioned running bead gear assembly has a flat design without space for opening the avoidance groove.

[0078] Based on this, a curtain running bead gear assembly is further provided 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, and an avoidance space 2 is formed between the vertical active transmission mechanism and the vertical passive transmission mechanism.

[0079] In an embodiment of the present utility model, a curtain bead gear assembly is provided, which includes a vertical driving transmission mechanism, a vertical driven transmission mechanism, and a horizontal transmission mechanism connected between the vertical driving transmission mechanism and the vertical driven transmission mechanism. The vertical driven transmission mechanism is linked with the vertical driving 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 driving transmission mechanism and the vertical driven 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.

[0080] 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.

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, and the stop edge extends upward from the curtain chute to the corresponding position of the light control rod.

[0082] The vertical driving transmission mechanism is driven by the light control rod 3 of the curtain, and the vertical driven transmission mechanism is used to drive the curtain hanging member 4. As a specific solution rather than a limitation, the vertical driving 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 driven transmission mechanism is used to transmit the power of the horizontal transmission mechanism from top to bottom to the curtain hanging member 4.

[0083] Specifically, the vertical driving transmission mechanism includes a light control rod socket part 5 coaxially arranged with the light control rod 3, and further includes a common adapter part linked with the light control rod socket part 5. The horizontal transmission mechanism includes the common adapter part and a first bevel gear body 6 linked with the common adapter part. The vertical driven transmission mechanism includes a second bevel gear body 7 linked with the first bevel gear body 6.

[0084] 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. 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.

[0085] In the solution of the present utility model, the first bevel gear body and the common adapter of the above-mentioned transverse transmission mechanism are integrally formed, or the first bevel gear body and the common adapter of the transverse transmission mechanism are separately assembled. Specifically in this embodiment, the first bevel gear body and the common adapter are separately assembled.

[0086] As a specific solution rather than a limitation, a worm helix 522 is formed on the outer wall surface of the ball bearing worm 52. The common adapter includes a ball bearing worm wheel 8. A worm gear 81 that cooperates with the worm helix 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 gears 81. The limiting rib 82 is at least used to limit the rotation angle of the ball bearing worm 52.

[0087] As a specific solution rather than a limitation, the ball bearing worm wheel 8 is horizontally arranged. 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 and includes a first bevel gear 61. It also 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. 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.

[0088] 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 also 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.

[0089] 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 a buckle 421 is 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.

[0090] 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 inventive concept of the present utility model all fall within the protection scope of the present utility model.

[0091] 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 between the second bevel gear body 7 and the curtain hanging member 4. Equivalent alternative solutions based on the inventive concept of the present utility model all fall within the protection scope of the present utility model.

[0092] As a preferred solution rather than a limitation, in order to improve the assembly convenience of the curtain bead and make the gear assemblies of each curtain bead have the same matching angle after assembly, so as to achieve the purpose that the angles of each curtain hanging member and each curtain sheet are the same in the later stage, a first standard alignment structure is provided on the first bevel gear body 6 of this embodiment, and a second standard alignment structure is provided on the second bevel gear body 7. The first standard alignment structure and the second standard alignment structure are used to unify at least the relative meshing angles of the first bevel gear body 6 and the second bevel gear body 7.

[0093] Specifically, the first standard alignment structure includes a positioning groove 63 opened on the first bevel gear body 6, and the second standard alignment structure includes a positioning protrusion opened on the second bevel gear body 7. The above positioning protrusion includes a positioning bump, a positioning flange or a positioning dot. In this embodiment, the positioning protrusion is a positioning flange 73.

The positioning flange 73 is opened on the inner wall surface of the bushing 72. Correspondingly, a alignment groove 422 is opened at a position corresponding to the positioning flange 73 on the clamping portion 42 of the curtain hanging member 4.

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 it to limit the dimming rod and prevent the dimming rod from slipping out of the curtain chute. By setting the curtain track structure 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 dimming rod from slipping out of the curtain chute. When processing the curtain track 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, which greatly improves the processing efficiency of the curtain track body, reduces the production process, and saves materials and assembly costs.

[0110] Sixth Embodiment:

[0111] When the curtain bead is installed on the curtain track, in view of achieving dimming, when the dimming rod rotates, a driving force will be generated to drive the overall left and right shaking of the curtain bead, resulting in noise. The difference between the embodiment of the present utility model and the above-mentioned fifth embodiment is that a height compensation member is further provided on the bead housing 1, 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 or more of the above shapes.

[0112] As a specific solution rather than a limitation, the protruding member 184 of this embodiment can adopt a cylindrical bottom and a hemispherical top. The number of the protruding members 184 can be two, which are respectively provided 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.

[0113] As a preferred solution rather than a limitation, the above-mentioned protruding member 184 can be integrally formed with the top cover 18.

[0114] This embodiment provides a bead housing with a height compensation member, which eliminates or reduces the longitudinal gap between the curtain bead and the corresponding cavity of the curtain track. 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 moving 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 when the curtain is working and improving the user experience.

[0115] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
