Description

Technical Field

[0001] This utility model relates to the field of electric curtain technology, specifically to an adjustable electric curtain track. Background Technology

[0002] Automatic curtains are also called motorized curtains. Automatic curtains are divided into fully automatic curtains and semi-automatic curtains. Fully automatic curtains are based on sunlight and temperature, and automatically open and close the curtains when the set light and temperature conditions are met. Semi-automatic curtains do not require you to walk to the window to manually pull the curtains; you can operate them with a handheld remote control device, such as a smartphone or a device similar to a TV remote control.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-9 An adjustable electric curtain track includes a track body 1, which includes a main track 11 and a secondary track 12. One end of the main track 11 is rotatably provided with a drive gear 112 and a drive gear 113, and the other end is rotatably provided with a transmission wheel 115 and a transmission wheel 116.

[0032] One end of the sub-track 12 is rotatably equipped with a driven gear 122, and the other end is equipped with a movable pulley 124.

[0033] The driving gear 112, driven gear 122, transmission wheel 115, and movable pulley 124 are all fitted with an independently rotatable adjustable track 13.

[0034] The drive gear 113 and the transmission wheel 116 are both fitted with a constant track 14 that can rotate independently.

[0035] The secondary track 12 is movably sleeved outside the main track 11. The distance between the two ends of the adjustable track 13 can be adjusted dynamically as the secondary track 12 and the main track 11 extend and retract. The distance between the two ends of the adjustable track 13 refers to the distance between the adjustable track 13 and the winding end of the drive gear 112 and the winding end of the adjustable track 13 and the driven gear 122. At the same time, the distance between the adjustable track 13 and the winding end of the transmission wheel 115 and the winding end of the adjustable track 13 and the winding end of the movable pulley 124 are also dynamically adjusted.

[0036] The adjustable track 13 and the constant track 14, together with the dual-axis motor, can independently control the opening and closing of the two sections of the curtain, allowing users to control them according to their preferences.

[0037] As a specific technical solution of this embodiment, a dual-shaft gearbox 111 is provided at one end of the main track 11. The first drive gear 112 and the second drive gear 113 are rotatably disposed inside the dual-shaft gearbox 111. A gearbox cover plate 1111 is provided on one side of the dual-shaft gearbox 111, and a motor mounting slot 1112 for mounting a dual-shaft motor is provided on the other side.

[0038] In this implementation scheme, the dual-axis motor is a common electric curtain dual-axis motor on the market. The two output shafts of the dual-axis motor can rotate independently or simultaneously, and the rotation directions can be different. The dual-axis motor can also be replaced by two single-axis motors. Several studs are arranged around the motor mounting slot 1112. The dual-axis motor can be assembled by using studs and screws. The internal cavity of the dual-axis gearbox 111 is provided for the independent installation of the first drive gear 112 and the second drive gear 113. The gearbox cover plate 1111 is fixedly installed on one side of the dual-axis gearbox 111 by screws. The gearbox cover plate 1111 is used to cover the first drive gear 112 and the second drive gear 113, which facilitates later inspection and maintenance.

[0039] As a specific technical solution of this embodiment, the end of the main track 11 away from the dual-shaft gearbox 111 extends into the interior of the secondary track 12 and is provided with a secondary transmission box 114. The first transmission wheel 115 and the second transmission wheel 116 are rotatably disposed inside the secondary transmission box 114, and a transmission box cover plate 1141 is provided on one side of the secondary transmission box 114.

[0040] In this embodiment, the interior of the secondary track 12 is provided with a cavity to avoid the secondary transmission box 114, which will not affect the telescopic movement between the secondary track 12 and the main track 11. The slide 15 is provided on one side of the cavity. The distance between the dual-shaft gearbox 111 and the secondary transmission box 114 remains unchanged. The transmission box cover plate 1141 is fixed to one side of the secondary transmission box 114 with screws to cover the first transmission wheel 115 and the second transmission wheel 116. The interior of the secondary rotating box is provided with a cavity for the independent installation of the first transmission wheel 115 and the second transmission wheel 116, which facilitates the later inspection and replacement of the first transmission wheel 115 and the second transmission wheel 116.

[0041] As a specific technical solution in this embodiment, one end of the auxiliary transmission box 114 is provided with at least one alignment rod 1142, and one end of the alignment rod 1142 extends into the interior of the main track 11.

[0042] In this embodiment, there are no fewer than two alignment rods 1142. One end of each alignment rod 1142 extends to the top and bottom of the inner cavity on one side of the main track 11, respectively. The alignment rods 1142 are interference-fitted with the main track 11, and the fastening is achieved by generating friction or deformation through the interference. External force is required during assembly, and greater force is required during disassembly, which ensures the connection stability between the auxiliary transmission box 114 and the main track 11.

[0043] As a specific technical solution in this embodiment, one end of the auxiliary transmission box 114 is also provided with a guide channel 1143 for guiding the adjustable track 13 and the constant track 14. One end of the guide channel 1143 extends into the interior of the main track 11 and is arc-shaped.

[0044] In this embodiment, the arc-shaped design of one end of the guide channel 1143 can reduce wear with the adjustable track 13 and the constant track 14. After one end of the guide channel 1143 is inserted into the inner cavity of the main track 11, it also has an interference fit with the inner cavity of the main track 11. There are multiple interference fit structures between the auxiliary transmission box 114 and the main track 11. During processing, the interference amount of the interference fit structure can be reduced, and the connection is stable while facilitating disassembly in the later stage.

[0045] As a specific technical solution of this embodiment, a single-shaft gearbox 121 is provided at one end of the sub-track 12, the driven gear 122 is rotatably disposed inside the single-shaft gearbox 121, and a gearbox cover plate 1211 is provided at one end of the single-shaft gearbox 121.

[0046] In this embodiment, the driven gear 122 is rotatably disposed inside the single-shaft gearbox 121. The gearbox cover plate 1211 is fixed to one side of the single-shaft gearbox 121 by screws to cover the driven gear 122, which facilitates the later maintenance and replacement of the driven gear 122.

[0047] As a specific technical solution of this embodiment, the end of the secondary track 12 away from the single-axis gearbox 121 is provided with a pulley mounting seat 123 that is movably sleeved with the outside of the main track 11. The pulley mounting seat 123 is provided with a support block 1231 extending into the inside of the main track 11. The movable pulley 124 is rotatably disposed inside the support block 1231. The end of the support block 1231 away from the pulley mounting seat 123 is provided with a mounting seat cover plate 1232.

[0048] In this embodiment, one end of the support block 1231 extends into the inner cavity of the main track 11 through a cavity. The mounting cover plate 1232 is disposed at one end of the support block 1231 to cover the movable pulley 124. A screw is inserted from one side of the pulley mounting seat 123, and the other end of the screw passes through the support block 1231 and is screwed into the interior of the mounting cover plate 1232 to fix the mounting cover plate 1232. This facilitates the later disassembly of the mounting cover plate 1232 to inspect and replace the movable pulley 124.

[0049] As a specific technical solution of this embodiment, a corresponding slide rail 15 is provided on one side of the main track 11 and the auxiliary track 12, a track connecting buckle 16 is provided on the adjustable track 13, and a track connecting buckle 2 17 is provided on the constant track 14.

[0050] In this embodiment, the adjustable track 13 is a long track before installation. After the two ends of the long track are passed over the driving gear 112, driven gear 122, transmission wheel 115 and movable pulley 124, the two ends of the long track are respectively inserted into the inside of the track connecting buckle 16. The inside of the track connecting buckle 16 is provided with track patterns that match the long track. There are two track connecting buckles 16. The two track connecting buckles 16 are placed side by side and a connecting piece and a curtain traction component 161 are installed on the end of the two track connecting buckles 16 that extends to the outside of the slide rail 15. Finally, screws are inserted into the inside of the connecting piece, the track connecting buckle 16 and the curtain traction component 161 to lock the three together.

[0051] As a specific technical solution in this embodiment, the end of the track connecting buckle 16 away from the adjustable track 13 passes through the slide rail 15 and is provided with a curtain traction component 161, and the end of the track connecting buckle 17 away from the constant track 14 passes through the slide rail 15 and is provided with a curtain traction component 171.

[0052] In this embodiment, before the constant track 14 is installed, it is a long track. After the two ends of the long track are passed over the second drive gear 113 and the second transmission wheel 116, the two ends of the long track are respectively inserted into the inside of the track connecting buckle 17. The inside of the track connecting buckle 17 is provided with track patterns that match the long track. There are two track connecting buckles 17. The two track connecting buckles 17 are placed side by side, and a connecting piece and a curtain traction component 171 are installed on the end of the two track connecting buckles 17 that extends to the outside of the slide rail 15. Finally, screws are inserted into the inside of the connecting piece, the track connecting buckle 17 and the curtain traction component 171 to lock the three together.

[0053] As a specific technical solution of this embodiment, the main track 11 is further provided with at least one curtain roller 18, the secondary track 12 is further provided with at least one curtain roller 19, the dual-axis gearbox 111 is provided with a roller mounting groove 1113 corresponding to the slide rail 15 on one side, and the single-axis gearbox 121 is provided with a roller mounting groove 1212 corresponding to the slide rail 15 on one side.

[0054] In this embodiment, curtain roller 18 and curtain roller 2 19 are used to suspend two sections of curtains respectively. One end of each section of curtain is connected to curtain traction component 161 and curtain traction component 2 171 respectively. The curtains are opened and closed by rotating the adjustable track 13 and the constant track 14. The roller mounting groove 1113 is used to install or remove curtain roller 18. The number of curtain roller 18 can be increased or decreased according to the width of the curtain, making it more convenient to use. The roller mounting groove 2 1212 is used to install or remove curtain roller 2 19. The number of curtain roller 2 19 can be increased or decreased according to the width of the curtain, making it more convenient to use.

[0055] Before leaving the factory, the main track 11 and the auxiliary track 12 are moved relative to each other, see [reference]. Figure 9 The distance between the movable pulley 124 and the driving gear 112 is shortened, and the distance between the transmission wheel 115 and the driven gear 122 is also shortened, which increases the distance between the transmission wheel 115 and the movable pulley 124. This design shortens the distance between the dual-shaft gearbox 111 and the single-shaft gearbox 121, greatly reducing the transportation space. After the main track 11 and the auxiliary track 12 are contracted together, the overall structural strength of the track body 1 is greatly increased. During on-site installation, the main track 11 and the auxiliary track 12 are pulled in opposite directions, increasing the distance between the movable pulley 124 and the driving gear 112, and increasing the distance between the transmission wheel 115 and the driven gear 122, which shortens the distance between the transmission wheel 115 and the movable pulley 124. After adjustment, the dual-shaft motor is installed, and it can be directly installed on the wall for use.

[0056] In summary, this adjustable electric curtain track, with its nested structure of main track 11 and secondary track 12, allows for free adjustment of its overall length. During transport, it retracts to its shortest form, significantly reducing packaging volume and logistics costs. The telescopic integrated design forms a rigid support structure in the folded state, enhancing bending resistance and effectively preventing damage during transport. On-site installation only requires stretching the track to automatically adjust the adjustable track 13 transmission system. The independent dual-track transmission ensures synchronization during the extension and retraction process, and allows for independent control of the opening and closing of the two curtain sections. This integrated telescopic solution reduces packaging and transportation costs while offering ease of assembly and reliable operation.
