[0053] Second Embodiment:

[0054] Please refer to Figures 1 to 12 As shown in the figure, the embodiment of the present utility model provides a connecting and driving box with a light-transmitting structure for connecting curtain track segments. The driving box includes a main gear 2 for cooperating with a curtain belt 1, and a docking gear 3 for transmitting power between the curtain track segments. The docking gear 3 rotates synchronously with the main gear 2, and the docking gear 3 is located above the main gear 2.

[0055] As a specific solution rather than a limitation, the curtain track segments in this embodiment can be track profiles 4.

[0056] The driving box includes a driving box housing 5. The driving box housing 5 forms at least a driving space 51 for arranging the docking gear 3 at the top, and at least the docking gear 3 can be disassembled and installed relative to the top of the driving box housing 5. As a specific solution rather than a limitation, the driving space 51 in this embodiment is also used for arranging the main gear 2, and the main gear 2 can be disassembled and installed relative to the top of the driving box housing 5.

[0057] Further, 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 disassembled and installed synchronously relative to the top of the transmission case housing 5.

[0058] The transmission case housing 5 includes an outer side surface 52, and a notch 511 is formed at a corresponding position of the transmission space 51 on the outer side surface 52, and the docking wheel exposes the notch 53. In this embodiment, two transmission cases are meshed with each other through the docking gear 3 to drive the belts 1 of the curtain tracks segmented on both sides of the two transmission cases to transmit power. The two transmission cases can be flexibly disassembled and assembled relative to each other through the alignment splicing structure 53, which has the advantages of flexibility and convenience.

[0059] At least a part of the top surface of the transmission case housing 5 near the outer side surface 52 is recessed downward to form the transmission space 511. As a preferred solution rather than a limitation, the transmission case further includes a top cover 6 provided above the docking gear 3, and the top cover 6 is detachably installed above the transmission space 51 through an assembly structure.

[0060] Specifically, the top surface of the top cover 6 is flush with the top surface of the side of the transmission case housing 5 away from the outer side surface. In this embodiment, the transmission case 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 case housing 5 is flush with the top of the top cover 6.

[0061] As a preferred solution rather than a limitation, an arc-shaped vertical wall 54 is further formed at the transmission space 51 of the transmission case housing 5, and 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.

[0062] 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.

[0063] In this embodiment, at least a columnar cavity 31 is formed in the middle of the docking gear 3. The top cover 6 includes a top stopping portion 61, and the top stopping portion 61 is used for extending into the columnar cavity 31 and at least stopping above the bearing 7 when the top cover 6 is installed above the transmission space 51.

[0064] The transmission case housing 3 further includes a column 542 provided in the middle of the annular vertical wall 54. A counterbore 543 is formed in the middle of the column 542. The assembly structure includes a screw and the counterbore 543, and the top cover is installed above the transmission space 51 through the cooperation of the screw and the counterbore 543.

[0065] 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 .

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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 .

[0073] 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 level with the lowest 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 that is level with the lowest 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 not being lower than the central height of the light-dimming rod 11 enables the first stop edge 9 to effectively limit the light-dimming rod 11, so as to more effectively prevent the light-dimming rod 11 from slipping out of the curtain chute 8.

[0074] 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 mortise-and-tenon structure, and / or a welding structure. The first stop edge is arranged perpendicular to the groove surface of the curtain chute.

[0075] 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.

[0076] 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 curtain bead 10 adjacent thereto.

[0077] 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-mentioned 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 prone to the phenomenon of slipping out 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.

[0078] As a preferred solution rather than a limitation of this embodiment, the transmission box housing 5 is further provided with a curtain bead position maintaining structure at the first space 55. The position maintaining structure includes a first compensation protrusion on the first space 55 relative to the inner side surface of the transmission box housing 5, and also includes a second compensation protrusion on the first space 55 relative to the inner bottom surface of the transmission box housing 5.

[0079] The first compensation protrusion and the second compensation protrusion are used to make up for the drop between the inner wall surfaces of the segmented curtain track and the inner wall surface of the transmission box housing, so as to ensure that when the curtain bead slides between the segmented curtain track and the connecting transmission box, the vertical height and horizontal position of the curtain bead 10 will not shift.

[0080] 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. The first compensation rib 57 and the second compensation rib 58 extend in the length direction of the curtain chute 8. Specifically, the second compensation rib 58 is used to support the light regulating rod fixing part 101 of the curtain bead 10. At the same time, since the contact area between the first compensation rib 57, the second compensation rib 58 and the light regulating rod fixing part 101 is small, the sliding friction of the curtain bead 10 can be reduced, and the overall sliding smoothness of the curtain bead 10 in the curtain track body can be improved.

[0081] The transmission box includes a plugging surface 501 for inserting the segmented curtain track. A docking surface 502 for cooperating with the end of the segmented curtain track is formed inside the transmission box on the plugging surface 501. An avoidance cavity 503 is formed inside the transmission box between the plugging surface 501 and the docking surface 502. The first stop edge 9 is arranged inside the docking surface 502.

[0082] In this embodiment, the above docking surface 502 is the starting surface of the first compensation rib 57 and the second compensation rib 58, and the first compensation rib 57 and the second compensation rib 58 extend towards the inner side of the transmission box housing 5. The above avoidance cavity 503 is used to accommodate the part of the segmented curtain track extending into the transmission box housing 5.

[0083] As a preferred solution rather than a limitation of this embodiment, a positioning rib 59 for docking with one side of the curtain chute 41 of the segmented curtain track is provided at the docking surface 502. The positioning rib 59 extends inwards from the docking surface 502, and the first stop edge 9 is arranged above the positioning rib 59. The positioning rib 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 positioning rib 59. When the segmented curtain track has a second stop edge 42, it is convenient for the shapes and sizes of the first stop edge 9 and the second stop edge 42 to be unified.

[0084] 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 box housing 5.

[0085] As a specific solution rather than a limitation of this embodiment, the interior of the transmission box 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.

[0086] By providing the above-mentioned connection transmission box in the embodiment of the present invention for connecting curtain rail segments, 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 on the curtain chute, and the first stop edge is located above one side of the notch of the curtain chute. The first stop edge of the transmission box can limit the dimming rod to prevent the dimming 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 rail body, there is no need 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 rail body, reducing the production process, and saving materials and assembly costs.

[0087] The transmission box of the present invention further includes a first light passing hole 12 provided on the front, upper and / or lower sides of the transmission box, and the first light passing hole 12 extends from the insertion face 501 to the inner end face 504.

[0088] As a preferred solution rather than a limitation of this embodiment, the first light passing hole 12 is opened on the front of the transmission box housing 5.

[0089] In this embodiment, the inner end face 504 is formed inside the transmission box housing 5, and the outer side face 52 is formed on the outside of the transmission box housing 5 for connecting to another transmission box. The first light passing hole 12 extends from the insertion face 501 to the outer side face 52, so that the first light passing hole 12 penetrates the entire length direction of the transmission box housing 5 and is conducive to connecting with the second light passing hole 43 of the curtain rail segment to form an overall light and shadow effect penetrating the curtain.

[0090] A relief space is formed inside the transmission box at the first light passing hole 12, and the relief space is used for the curtain light source 13 to extend in. In this embodiment, the relief space communicates with the relief cavity 503.

[0091] As a specific solution rather than a limitation of this embodiment, a vertical surface 505 is formed at the lower part of the front of the transmission case housing 5. At least part of the top surface of the transmission case housing 5 is recessed downward near one side of the outer side surface to form a transmission space 51. A first convex edge 506 is provided on the top surface of the transmission case housing 5 on the side far from the outer side surface, that is, the first convex edge 506 is formed on the inner top surface of the transmission case housing 5. A first segment 121 of the first light passing 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 the corresponding position of the first convex edge 56. A second segment 122 of the first light passing 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 passing hole and the second segment 122 of the first light passing hole are combined to form the first light passing hole 12.

[0092] As a preferred solution rather than a limitation of this embodiment, the transmission case housing 5 further forms a vertical wall 507 on the front of the transmission space 51, and the vertical wall 507 is used for arranging the curtain light source 13.

[0093] The curtain track segment corresponding to this embodiment includes a light source installation surface 44 for arranging the curtain light source. When the curtain track segment is installed in the transmission case, the surfaces of the vertical wall 507 and the light source installation surface 44 are flush.

[0094] The curtain track segment corresponding to this embodiment includes a second light passing hole 43 located at the front end of the curtain light source. When the curtain track segment is installed in the transmission case, the first light passing hole 12 is aligned with the second light passing hole 43, and the first light passing hole 12 is located outside the second light passing hole 43.

[0095] The above solution ensures the convenience of arranging the curtain light source 13, and enables a complete linear light source to be used to arrange along the length direction formed by all curtain track segments and the connecting transmission case, 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 improving the overall light emission consistency of the curtain and enhancing the user experience.

[0096] 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-transmitting 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-transmitting 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-transmitting hole, and the transmission box forms a second lower mounting edge 5051 at the second segment 122 of the vertical surface 505 relative to the first light-transmitting 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.

[0097] Further, 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-transmitting hole, and the transmission box forms a third lower mounting edge 5052 at the first segment 121 of the vertical surface 505 relative to the first light-transmitting 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.

[0098] 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 segment and the connection 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 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.

[0099] 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.

[0100] The embodiment of the present invention provides a connection transmission box with a light-transmitting structure. The transmission box includes a plugging surface for plugging the curtain rail segment, and an inner end surface opposite to the plugging surface, and further includes a first light-transmitting hole provided on the front, upper, and / or lower sides of the transmission box, and the first light-transmitting hole extends from the plugging surface to the inner end surface. The second light-transmitting hole on the curtain rail segment can be communicated with the first light-transmitting hole on the front, upper, and / or lower sides of the connection transmission box, so that the light of the light source located on the curtain can diverge within a horizontal range including but not limited to the curtain rail body and the transmission box, enabling the light of the light source to be organically combined with the curtain as a whole, enhancing the integrated effect of the curtain light, and facilitating the creation of a warm and comfortable home atmosphere.

[0101] 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 replacements, 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.
