[0047] Second embodiment:

[0048] Please refer to Figures 1 to 12As shown in the figure, an embodiment of the present utility model provides a connecting drive box for a dream curtain, which is used to connect segmented curtain tracks. The drive box includes a main gear 2 for cooperating with a curtain belt 1, and a docking gear 3 for transmitting power between the segmented curtain tracks. The docking gear 3 rotates synchronously with the main gear 2, and the docking gear 3 is located above the main gear 2.

[0049] As a specific solution rather than a limitation, the segmented curtain tracks in this embodiment can be track profiles 4.

[0050] The drive box includes a drive box housing 5. The drive box housing 5 forms at least a drive space 51 at the top for the docking gear 3 to be arranged. At least the docking gear 3 can be disassembled and installed relative to the top of the drive box housing 5. As a specific solution rather than a limitation, the drive space 51 in this embodiment is also used for the main gear 2 to be arranged, and the main gear 2 can be disassembled and installed relative to the top of the drive box housing 5.

[0051] Furthermore, in this embodiment, the main gear 2 and the docking gear 3 are integrally formed so that the main gear 2 and the docking gear 3 can be synchronously disassembled and installed relative to the top of the drive box housing 5.

[0052] The drive box housing 5 includes an outer side surface 52. The drive space 51 forms a notch 511 at the corresponding position of the outer side surface 52, and the docking wheel exposes the notch 53. In this embodiment, two drive boxes are meshed with each other through the docking gear 3 to drive the belts 1 of the curtain tracks on both sides of the two drive boxes to transmit power. The two drive boxes can be flexibly disassembled and assembled relatively through the alignment splicing structure 53, which has the advantages of flexibility and convenience.

[0053] At least part of the top surface of the drive box housing 5 near the outer side surface 52 is recessed downward to form the drive space 511. As a preferred solution rather than a limitation, the drive box further includes a top cover 6 arranged above the docking gear 3. The top cover 6 is detachably installed above the drive space 51 through an assembly structure.

[0054] Specifically, the top surface of the top cover 6 is flush with the top surface of the side of the drive box housing 5 away from the outer side surface. In this embodiment, the drive box housing 5 includes an inner top surface and an outer top surface. The outer top surface is recessed downward to form a drive space, and the inner top surface of the drive box housing 5 is flush with the top of the top cover 6.

[0055] As a preferred solution rather than a limitation, the drive box housing 5 also forms an arc-shaped vertical wall 54 at the drive space 51. A belt turning cavity for accommodating the main gear 2 and the turning part of the belt 1 is formed inside the arc-shaped vertical wall 54.

[0056] As a preferred solution rather than a limitation, the transmission case housing 5 further includes an annular vertical wall 541 provided in the middle of the arc-shaped vertical wall 54. The transmission case further includes a bearing 7 sleeved on the annular vertical wall 541, and at least the main gear 2 is arranged on the bearing 7.

[0057] In this embodiment, at least the docking gear 3 forms a columnar cavity 31 in the middle. The top cover 6 includes a top stopping portion 61. When the top cover 6 is installed above the transmission space 51, the top stopping portion 61 is used to extend into the columnar cavity 31 and at least stop above the bearing 7.

[0058] The transmission case housing 3 further includes a column 542 provided in the middle of the annular vertical wall 54. A counterbore 543 is provided in the middle of the column 542. The assembly structure includes a screw and the counterbore 543. The top cover is installed above the transmission space 51 through the cooperation of the screw and the counterbore 543.

[0059] The column 542 extends into the columnar cavity 31. When the top cover 6 is installed above the transmission space 51, the top cover 6 abuts against the top end of the column 542.

[0060] The transmission case of this embodiment includes a curtain sliding groove 8 provided at the bottom. At least one first stop edge 9 is provided at a corresponding position of the transmission case with respect to the curtain sliding groove 8. The first stop edge 9 is located above one side of the notch of the curtain sliding groove 8.

[0061] As a preferred solution rather than a limitation of this embodiment, the first stop edge 9 extends from the notch of the curtain sliding groove 9 to above the notch.

[0062] As a specific solution rather than a limitation of this embodiment, the transmission case housing 5 forms the curtain sliding groove 8 at the bottom. A first space 55 for arranging the light-adjusting rod fixing portion 101 of the curtain bead 10 is formed inside the transmission case housing 5 on one side of the curtain sliding groove 8. A second space 56 for arranging the curtain hanging member fixing portion 102 of the curtain bead 10 is formed inside the transmission case housing 5 on the other side of the curtain sliding groove. The first stop edge 9 is arranged between the first space 55 and the curtain sliding groove 8.

[0063] In this embodiment, the transmission case housing 5 extends upward from one side corresponding to the first space 55 of the curtain sliding groove 8 to form the first stop edge 9.

[0064] The first stop edge 9 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 11. When the height of the top end of the first stop edge 9 is at the same level as the lowest end height of the light-dimming rod 11, due to the natural deformation of the light-dimming rod 11 under the action of gravity, the light-dimming rod 11 will present a natural downward-bending arc, so that the top end of the first stop edge 9 at the same level as the lowest end height of the light-dimming rod 11 can limit part of the downward-bending light-dimming rod 11, which can play a certain role in preventing the light-dimming rod 11 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 11. The height of the top end of the first stop edge 9 is not lower than the central height of the light-dimming rod 11, so that the first stop edge 9 can effectively limit the light-dimming rod 11 to more effectively prevent the light-dimming rod 11 from slipping out of the curtain chute 8.

[0065] It should be noted that in some other embodiments of the present utility model, the first stop edge can also be fixed on the curtain chute through an assembly structure. The assembly structure includes a slot, a buckle, a screw, a clamping mechanism, a tenon-and-mortise structure, and / or a welding structure. The first stop edge is arranged perpendicular to the groove surface of the curtain chute.

[0066] When the first stop edge can be disassembled and assembled relative to the transmission box housing through an assembly structure, the manufacturer or user can select the installation quantity of the first stop edge and the installation position of the first stop edge relative to the transmission box housing according to their own needs, so as to improve the processing efficiency of the transmission box housing while making the fixation of the first stop edge to the light-dimming rod more flexible and convenient.

[0067] In this embodiment, the first stop edge 9 includes a bent portion 91, and at least the bent portion 91 corresponds to the position of a part of the side surface of the light-dimming rod fixing portion 101 of the adjacent curtain bead 10.

[0068] It should be noted that in some other embodiments of the present utility model, the number of the first stop edges is multiple, and the multiple first stop edges are spaced apart in the length direction of the curtain chute. As a specific solution rather than a limitation, the shapes and heights of the above multiple first stop edges can be different. When all the 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 likely to be disengaged at the connection with the transmission box. Therefore, the height of the first stop edge near the outer side surface in the transmission box is the highest to facilitate the fixation of the middle part of the light-dimming rod.

[0069] As a preferred solution of this embodiment but not a limitation, the transmission box housing 5 is also provided with a curtain ball position maintaining structure in the first space 55, and the position maintaining structure includes a first compensation protrusion located in the first space 55 relative to the inner side surface of the transmission box housing 5, and also includes a second compensation protrusion located in the first space 55 relative to the inner bottom surface of the transmission box housing 5.

[0070] The first compensation protrusion and the second compensation protrusion are used to make up for the difference between the inner wall surface of the curtain track segment and the inner wall surface of the transmission box housing, so as to ensure that the vertical height and horizontal position of the curtain beads 10 will not be offset when the curtain beads slide between the curtain track segment and the connecting transmission box.

[0071] As an improvement to the above solution, the first compensation protrusion is at least one first compensation rib 57, and the second compensation protrusion is at least two second compensation ribs 58, and the first compensation rib 57 and the second compensation rib 58 extend in the length direction of the curtain slide 8. Specifically, the second compensation rib 58 is used to support the dimming rod fixing part 101 of the curtain roller 10. At the same time, since the contact area between the first compensation rib 57, the second compensation rib 58 and the dimming rod fixing part 101 is small, the sliding friction of the curtain roller 10 can be reduced, and the overall sliding smoothness of the curtain roller 10 in the curtain track body can be improved.

[0072] The transmission box includes a plug-in surface 501 for plugging in the curtain rail segments, and a docking surface 502 is formed on the inner side of the plug-in surface 501 of the transmission box to cooperate with the end of the curtain rail segment. An avoidance cavity 503 is formed inside the transmission box between the plug-in surface 501 and the docking surface 502, and the first stop edge 9 is arranged on the inner side of the docking surface 502.

[0073] In this embodiment, the above-mentioned docking surface 502 is the starting surface of the first compensation ridge 57 and the second compensation ridge 58, and the first compensation ridge 57 and the second compensation ridge 58 extend toward the inner side of the transmission box housing 5. The above-mentioned avoidance cavity 503 is used to accommodate the part of the curtain track extending into the transmission box housing 5 in sections.

[0074] As a preferred solution of this embodiment but not a limitation, the docking surface 502 is provided with a aligning ridge 59 that docks with one side of the curtain chute 41 of the curtain track segment, and the aligning ridge 59 extends inward from the docking surface 502, and the first stop edge 9 is arranged above the aligning ridge 59. The aligning ridge 59 is used to compensate for the thickness of the track profile 4 on one side of the curtain chute notch, so as to facilitate the independence of the shape of the first stop edge 9 arranged above the aligning ridge 59. When the curtain track segment has the second stop edge 42, it is convenient for the first stop edge 9 and the second stop edge 42 to be unified in shape and size.

[0075] Specifically, the first stop edge 9 extends along the length direction of the alignment rib 59, and the length of the first stop edge 9 corresponds to the length of the alignment rib 59. Specifically, the alignment rib 59 and the first stop edge 9 are integrally formed on the transmission case housing 5.

[0076] As a specific solution rather than a limitation of this embodiment, the interior of the transmission case includes an inner end face 504 disposed opposite to the insertion face 501, and the alignment rib 59 and the first stop edge 9 extend from the docking face 502 to the inner end face 504.

[0077] The embodiment of the present utility model provides the above-mentioned connection transmission case for connecting curtain track segments. The transmission case includes a curtain chute provided at the bottom, and at least one first stop edge is provided at a corresponding position of the transmission case with respect to the curtain chute. The first stop edge is located above one side of the notch of the curtain chute. The first stop edge of the transmission case can limit the light-adjusting rod to prevent the light-adjusting rod from slipping out of the curtain chute. On the one hand, the width of the curtain chute of the transmission case can be increased, improving the processing efficiency of the transmission case. On the other hand, when processing the curtain track body, it is not necessary to deliberately reduce the width of the curtain chute, and there is no need to use a flexible support member to further limit the width of the curtain chute, greatly improving the processing efficiency of the curtain track body, reducing the production process, and saving materials and assembly costs.

[0078] Since the function of traditional curtains is usually to adjust the indoor light by changing the light transmission amount of the window. With the improvement of people's living standards, the degree of attention paid by users to the quality of life is also increasing day by day. Based on this, intelligent electric curtains have emerged.

[0079] However, at present, the improvement of intelligent electric curtains still mainly focuses on the basic opening and closing function of the curtains, lacking corresponding attention to how to create a more warm and comfortable home atmosphere. If point light sources are directly distributed on the curtain track body, they cannot be organically combined with the whole curtain, the integrated feeling is not strong, the created light and shadow effect is limited, and the improvement of the user's quality of life is limited.

[0080] To overcome the above defects, the transmission case of the present utility model further includes a first light-transmitting hole 12 provided on the front, above and / or below the transmission case. The first light-transmitting hole 12 extends from the insertion face 501 to the inner end face 504.

[0081] As a preferred solution rather than a limitation of this embodiment, the first light-transmitting hole 12 is opened on the front of the transmission case housing 5.

[0082] The inner end surface 504 of the present embodiment is formed inside the transmission box housing 5, and the outer side surface 52 is formed on the transmission box housing 5 for connecting to the outside of another transmission box. The first light-through hole 12 extends from the plug-in surface 501 to the outer side surface 52, so that the first light-through hole 12 runs through the entire length direction of the transmission box housing 5, and is conducive to connecting with the second light-through hole 43 of the curtain track segment to form a light and shadow effect that runs through the curtain as a whole.

[0083] The transmission box is formed with an escape space inside the first light-through hole 12 , and the escape space is used for the curtain light source 13 to extend into. In this embodiment, the escape space is communicated with the escape cavity 503 .

[0084] As a specific solution of this embodiment but not limitation, the transmission box housing 5 forms a vertical surface 505 below the front surface, the top surface of the transmission box housing 5 is at least partially recessed downward on the side close to the outer side surface to form a transmission space 51, and the top surface of the transmission box housing 5 is provided with a first convex edge 506 on the side away from the outer side surface, that is, the first convex edge 506 is formed on the inner top surface of the transmission box housing 5, and the first segment 121 of the first light-through hole 12 is formed between the vertical surface 505 and the first convex edge 56. The top cover 6 is provided with a second convex edge 62 adjacent to the first convex edge 56 at a corresponding position of the first convex edge 56, and the second segment 122 of the first light-through hole 12 is formed between the vertical surface 505 and the second convex edge 62. In this embodiment, the first segment 121 of the first light-through hole and the second segment 122 of the first light-through hole are combined to form the first light-through hole 12.

[0085] As a preferred solution of this embodiment but not limitation, the transmission box housing 5 is further formed with a vertical wall 507 on the front side of the transmission space 51 , and the vertical wall 507 is used for arranging the curtain light source 13 .

[0086] The curtain track segment corresponding to this embodiment includes a light source installation surface 44 for arranging a curtain light source. When the curtain track segment is installed in the transmission box, the surface of the upright wall 507 is flush with the surface of the light source installation surface 44.

[0087] The curtain track segment corresponding to this embodiment includes a second light-through hole 43 located at the front end of the curtain light source. When the curtain track segment is installed in the transmission box, the first light-through hole 12 is aligned with the second light-through hole 43, and the first light-through hole 12 is located on the outside of the second light-through hole 43.

[0088] While the above solution ensures the convenience of arranging the curtain light source 13, it enables the arrangement to be achieved with only one complete linear light source in the length direction formed by all the curtain rail segments and the connecting transmission boxes, ensuring the uniformity and consistency of the curtain light source 13. At the same time, the first light-passing hole 12 and the second light-passing hole 43 are aligned, further enhancing the overall light-emitting consistency of the curtain and improving the user experience.

[0089] As a preferred solution rather than a limitation of this embodiment, the curtain rail segment includes a first upper mounting edge 45 located above the second light-passing hole 43 for fixing the light-transmitting cover 14, the curtain rail segment includes a first lower mounting edge 46 located below the second light-passing hole 43 for fixing the light-transmitting cover 14, the transmission box forms a second upper mounting edge 621 at the second segment 122 of the second convex edge 62 relative to the first light-passing hole, and the transmission box forms a second lower mounting edge 5051 at the elevation 505 relative to the second segment 122 of the first light-passing hole. When the curtain rail segment is installed in the transmission box, the second upper mounting edge 621 is aligned with the first upper mounting edge 45, and the second lower mounting edge 5051 is aligned with the first lower mounting edge 46.

[0090] Furthermore, the transmission box forms a third upper mounting edge 5061 at the first segment 121 of the first convex edge 506 relative to the first light-passing hole, and the transmission box forms a third lower mounting edge 5052 at the elevation 505 relative to the first segment 121 of the first light-passing hole. When the top cover 6 is installed on the transmission box housing 5, the third lower mounting edge 5052 is aligned with the first lower mounting edge 46, and the third upper mounting edge 5061 is aligned with the first upper mounting edge 45.

[0091] The above solution enables the first, second, and third upper mounting edges to be aligned, and the first, second, and third lower mounting edges to be aligned, so that only one complete light-transmitting cover can be integrally installed in the length direction formed by the curtain rail segments and the connecting transmission boxes. At the same time, since the light-transmitting cover is fixed by the first, second, and third upper mounting edges, and the first, second, and third lower mounting edges throughout the entire length direction, the light-transmitting cover has a very stable fixing effect, preventing the light-transmitting cover from deforming and causing light leakage after long-term use.

[0092] The second convex edge 62 includes an inner edge and an outer edge, and the second upper mounting edge 621 is formed on the inner edge. The above first, second, and third upper mounting edges, and the first, second, and third lower mounting edges can fix the light-transmitting cover 14 through a snap structure.

[0093] In an embodiment of the present utility model, a connection transmission box with a light-transmitting structure is provided. The transmission box includes a plugging surface for segmentally plugging a curtain track, and an inner end surface disposed opposite to the plugging surface. It further includes first light-passing holes provided on the front, upper, and / or lower sides of the transmission box, and the first light-passing holes extend from the plugging surface towards the inner end surface. This enables the second light-passing holes on the segmented curtain track to communicate with the first light-passing holes on the front, upper, and / or lower sides of the connection transmission box, allowing the light of the light source located on the curtain to diverge within a horizontal range including but not limited to the curtain track body and the transmission box, integrating the light source light with the entire curtain, enhancing the integrated effect of the curtain light, and facilitating the creation of a warm and comfortable home atmosphere.

[0094] Third Embodiment:

[0095] Please refer to Figure 6 、 Figure 7 and Figure 12 As shown in, an embodiment of the present utility model provides a dream curtain, which includes at least two segmented curtain tracks, and the segmented curtain tracks are connected by the connection transmission box applied to the dream curtain described in the above second embodiment.

[0096] The dream curtain includes a light-adjusting rod 11 provided on a curtain bead 10, and a second stop edge 42 for preventing the light-adjusting rod 11 from slipping out of a curtain chute is provided on the segmented curtain track.

[0097] The cross-sectional shape and size of the second stop edge 42 are the same as those of the first stop edge 9. When the segmented curtain track is connected through the transmission box, the second stop edge 42 and the first stop edge 9 are aligned.

[0098] In an embodiment of the present utility model, a connection transmission box applied to a dream curtain is provided for connecting segmented curtain tracks. The transmission box includes a curtain chute provided at the bottom, and at least one first stop edge is provided at a corresponding position of the transmission box with respect to the curtain chute, and the first stop edge is located above one side of the notch of the curtain chute. This enables the first stop edge of the transmission box to limit the light-adjusting rod and prevent the light-adjusting rod from slipping out of the curtain chute. On the one hand, the width of the curtain chute of the transmission box can be increased, improving the processing efficiency of the transmission box. On the other hand, when processing the curtain track body, there is no need 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, greatly improving the processing efficiency of the curtain track body, reducing the production process, and saving materials and assembly costs.

[0099] The above are only preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
