[0056] Second embodiment:

[0057] Please refer to Figures 1 to 12 As shown, an embodiment of the utility model provides a transmission box for connecting curtain track segments, the transmission box includes a main gear 2 for cooperating with a curtain belt 1, and a docking gear 3 for transmitting power between each curtain track segment, the docking gear 3 rotates synchronously with the main gear 2, and the docking gear 3 is located on the upper part of the main gear 2.

[0058] As a specific solution but not limitation, the curtain track segment of this embodiment can be a track profile 4.

[0059] The transmission box includes a transmission box housing 5, and the transmission box housing 5 forms a transmission space 51 at the top for at least setting the docking gear 3, and at least the docking gear 3 can be removed and installed relative to the top of the transmission box housing 5. As a specific solution but not a limitation, the transmission space 51 of this embodiment is also used for setting the main gear 2, and the main gear 2 can be removed and installed relative to the top of the transmission box housing 5.

[0060] 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 transmission box housing 5.

[0061] The transmission box housing 5 includes an outer side 52, the transmission space 51 forms a notch 511 at a corresponding position of the outer side 52, and the docking gear exposes the notch 53. In this embodiment, two transmission boxes are meshed with each other through docking gears 3 to drive the belts 1 of the curtain track segments on both sides of the two transmission boxes to transmit power. The two transmission boxes can be relatively flexibly disassembled and assembled through the alignment splicing structure 53, which has the advantages of flexibility and convenience.

[0062] The top surface of the transmission box housing 5 is at least partially recessed downward on one side close to the outer side surface 52 to form the transmission space 511. As a preferred solution but not a limitation, the transmission box further includes a top cover 6 disposed above the docking gear 3, and the top cover 6 is detachably mounted above the transmission space 51 through an assembly structure.

[0063] Specifically, the top surface of the top cover 6 is flush with the top surface of the side of the transmission box housing 5 away from the outer side surface. In this embodiment, the transmission box housing 5 includes an inner top surface and an outer top surface, the outer top surface is recessed downward to form a transmission space, and the inner top surface of the transmission box housing 5 is flush with the top of the top cover 6.

[0064] As a preferred solution but not a limitation, the transmission box housing 5 is further formed with an arc-shaped vertical wall 54 at the transmission space 51 , and a belt turning cavity is formed inside the arc-shaped vertical wall 54 for accommodating the main gear 2 and the turning part of the belt 1 .

[0065] As a preferred solution but not a limitation, the transmission box housing 5 also includes an annular vertical wall 541 arranged in the middle of the arc-shaped vertical wall 54 , and the transmission box also includes a bearing 7 sleeved on the annular vertical wall 541 , and at least the main gear 2 is arranged on the bearing 7 .

[0066] In this embodiment, at least the docking gear 3 forms a cylindrical cavity 31 in the middle, and the top cover 6 includes a top stop portion 61, which is used to extend into the cylindrical cavity 31 and at least stop above the bearing 7 when the top cover 6 is installed above the transmission space 51.

[0067] The transmission box housing 3 also includes a column 542 arranged in the middle of the annular wall 54, a countersunk hole 543 is opened in the middle of the column 542, the assembly structure includes screws and the countersunk hole 543, and the top cover is installed above the transmission space 51 by the cooperation of the screws and the countersunk hole 543.

[0068] 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 of the column 542 .

[0069] Because the curtain track of the dream curtain requires an additional installation position for the dimmer rod compared to the ordinary electric opening and closing curtain, in order to prevent the dimmer rod from falling out of the curtain slide at the bottom of the curtain track, on the one hand, it is necessary to reduce the width of the curtain slide at the curtain track and the transmission box, and on the other hand, it is necessary to set a flexible support above the curtain slide to adjust the width of the curtain slide.

[0070] However, the small width of the curtain chute greatly affects the processing efficiency of the curtain track and the transmission box. In addition, the flexible support member disposed above the curtain chute also increases the production process and material and assembly costs. Therefore, it is necessary to provide a connecting transmission box and a dream curtain that are suitable for omitting the flexible support member and ensuring that the curtain chute is in a suitable width for processing.

[0071] To overcome the above-mentioned defects, the transmission box of this embodiment includes a curtain slide 8 arranged at the bottom, and the transmission box is provided with at least one first stop edge 9 at the corresponding position of the curtain slide 8, and the first stop edge 9 is located above one side of the notch of the curtain slide 8.

[0072] As a preferred solution of this embodiment but not limitation, the first stop edge 9 extends from the notch of the curtain slide 9 to above the notch.

[0073] As a specific solution of this embodiment but not limitation, the transmission box housing 5 forms the curtain chute 8 at the bottom. A first space 55 for setting the dimming rod fixing part 101 of the curtain roller 10 is formed inside the transmission box housing 5 on one side of the curtain chute 8, and a second space 56 for setting the curtain hanging fixing part 102 of the curtain roller 10 is formed inside the transmission box housing 5 on the other side of the curtain chute, and the first stop edge 9 is arranged between the first space 55 and the curtain chute 8.

[0074] In this embodiment, the transmission box housing 5 extends upward from one side of the curtain sliding groove 8 corresponding to the first space 55 to form the first stop edge 9 .

[0075] The first stop edge 9 includes a top. In some optional solutions covered by the protection scope of the utility model, the height of the top can be lower than the center height of the dimming rod 11. When the height of the top of the first stop edge 9 is equal to the height of the bottom end of the dimming rod 11, the dimming rod 11 will naturally bend downward due to the natural deformation of the dimming rod 11 under the action of gravity, so that the top of the first stop edge 9, which is equal to the height of the bottom end of the dimming rod 11, can limit the part of the dimming rod 11 that is bent downward, and can play a certain role in preventing the dimming rod 11 from falling out of the curtain chute. Preferably, in this embodiment, the height of the top is not lower than the center height of the dimming rod 11. The height of the top of the first stop edge 9 is not lower than the center height of the dimming rod 11, so that the first stop edge 9 can effectively limit the dimming rod 11, so as to more effectively prevent the dimming rod 11 from falling out of the curtain chute 8.

[0076] It should be noted that, in some other embodiments of the present invention, the first stop edge can also be fixed to the curtain slide groove through an assembly structure, and the assembly structure includes a slot, a buckle, a screw, a clamping mechanism, a mortise and tenon structure and / or a welding structure, and the first stop edge is arranged perpendicular to the groove surface of the curtain slide groove.

[0077] When the first stop edge can be disassembled and assembled relative to the transmission box housing through the assembly structure, the manufacturer or user selects the number of first stop edges to be installed 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 and make the first stop edge more flexible and convenient in fixing the dimming rod.

[0078] In this embodiment, the first stop edge 9 includes a bent portion 91 , and at least the bent portion 91 corresponds to a position of a portion of a side surface of a dimming rod fixing portion 101 of the curtain roller 10 adjacent thereto.

[0079] It should be noted that in some other embodiments of the 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 slide. As a specific solution but not a limitation, the shapes and heights of the 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, the dimming rod in the middle of the curtain track body is deformed the most by gravity, so the dimming rod is easy to fall out at the connection transmission box. Therefore, the height of the first stop edge located near the outer side of the transmission box is the highest, so as to facilitate the fixation of the middle of the dimming rod.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] Specifically, the first stop edge 9 extends in 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 box housing 5.

[0087] As a specific solution of this embodiment but not limitation, the transmission box includes an inner end surface 504 arranged opposite to the plug-in surface 501 , and the alignment ridge 59 and the first stop edge 9 extend from the docking surface 502 to the inner end surface 504 .

[0088] The embodiment of the utility model provides the above-mentioned connecting transmission box for connecting the curtain track segments, the transmission box includes a curtain slide groove arranged at the bottom, and the transmission box is provided with at least one first stop edge at the corresponding position of the curtain slide groove, and the first stop edge is located above one side of the notch of the curtain slide groove. The first stop edge of the transmission box can limit the dimming rod to prevent the dimming rod from escaping from the curtain slide groove. On the one hand, the width of the curtain slide groove of the transmission box can be increased, and the processing efficiency of the transmission box can be improved. On the other hand, when processing the curtain track body, there is no need to deliberately reduce the width of the curtain slide groove, and there is no need to use a flexible support member to further limit the width of the curtain slide groove, which greatly improves the processing efficiency of the curtain track body, reduces the production process, and saves material and assembly costs.

[0089] Since the function of traditional curtains is usually to adjust the indoor light by changing the amount of light passing through the window, as people's living standards improve, users pay more and more attention to the quality of life, based on which smart electric curtains appear.

[0090] However, the current improvements of smart electric curtains are still more focused on the basic opening and closing functions of curtains, and lack 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, it cannot be organically integrated with the curtain as a whole, the sense of integration is not strong, the light and shadow effects created are limited, and the improvement of the user's quality of life is limited.

[0091] To overcome the above defects, the transmission box of the present invention further comprises a first light-through hole 12 arranged on the front, top and / or bottom of the transmission box, and the first light-through hole 12 extends from the plug-in surface 501 to the inner end surface 504 .

[0092] As a preferred solution of this embodiment but not a limitation, the first light-through hole 12 is opened on the front side of the transmission box housing 5 .

[0093] 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.

[0094] 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 .

[0095] 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.

[0096] 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 .

[0097] 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.

[0098] 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.

[0099] The above solution ensures the convenience of arranging the curtain light source 13, and only one complete linear light source is needed to be arranged in the length direction formed by all curtain track segments and the connecting transmission box, thereby ensuring the uniformity and consistency of the curtain light source 13. At the same time, the first light hole 12 and the second light hole 43 are aligned, further improving the overall light emission consistency of the curtain and enhancing the user experience.

[0100] As a preferred solution of this embodiment but not a limitation, the curtain track segment includes a first upper mounting edge 45 located on the upper side of the second light-through hole 43 for fixing the light-transmitting cover 14, and the curtain track segment includes a first lower mounting edge 46 located on the lower side of the second light-through 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 first light-through hole on the second convex edge 62, and the transmission box forms a second lower mounting edge 5051 at the second segment 122 of the first light-through hole on the facade 505. When the curtain track 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.

[0101] Furthermore, the transmission box forms a third upper mounting edge 5061 at the first convex edge 506 relative to the first section 121 of the first light-transmitting hole, and the transmission box forms a third lower mounting edge 5052 at the first section 121 of the first light-transmitting hole at the facade 505. 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.

[0102] The above scheme 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 a complete light-transmitting cover can be installed in an integrated manner in the length direction formed by the curtain track segment and the connecting transmission box. 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 in 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.

[0103] The second protruding edge 62 includes an inner edge and an outer edge, and the second upper mounting edge 621 is formed on the inner edge. The 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 buckle structure.

The second light-through hole on the segmented curtain track can be connected with the first light-through hole on the front, top and / or bottom of the connecting transmission box, so that the light of the light source located on the curtain can be diverged in the lateral range including but not limited to the curtain track body and the transmission box, so that the light of the light source is organically combined with the curtain as a whole, thereby enhancing the integrated effect of the curtain light and creating a warm and comfortable home atmosphere.

[0105] The embodiment of the utility model provides a transmission box, including a main gear for cooperating with a curtain belt, and a docking gear for transmitting power between each curtain track segment, wherein the docking gear rotates synchronously with the main gear, and the docking gear is located on the upper part of the main gear. Since the main gear cooperates with the curtain belt, and the docking gear is located on the upper part of the main gear, the docking gear and / or the main gear can be easily disassembled from the top of the docking transmission box without being limited by the vertical direction of the curtain belt, thereby improving the convenience of the overall assembly and disassembly of the docking transmission box.

[0106] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
