[0025] like Figure 1 and Figure 2 As shown, the present invention relates to a cord-type control system for driving a roller blind, comprising a power module 1, a battery 2, a roller blind drive mechanism 3, a master control module 4, and a cord-drawing adjustment mechanism 5, wherein the battery 2 is electrically connected to the power module 1, the roller blind drive mechanism 3 is electrically connected to the battery 2 and the master control module 4, respectively, the master control module 4 is electrically connected to the power module 1, and the cord-drawing adjustment mechanism 5 is electrically connected to the master control module 4.

[0026] In this rope-type control system, a power module 1, a battery 2, a roller shutter drive mechanism 3, a master control module 4 and a rope-pull adjustment mechanism 5 are used, and the power module 1, the battery 2, the roller shutter drive mechanism 3, the master control module 4 and the rope-pull adjustment mechanism 5 adopt the above electrical connection structure, so that the roller shutter drive mechanism 3 can be conveniently switched on and off through the rope-pull adjustment mechanism 5, which eliminates the need to set a separate switch component on the wall and the need to connect the switch component with an external wire, which can effectively simplify the installation and maintenance process, which can greatly improve the installation efficiency and the convenience of maintenance, and thus can solve a lot of troubles for users.

[0027] like Figure 1 、 Figure 2 、 Figures 4 to 7 As shown, the pull-cord control system for driving roller blinds also includes a housing 6, and the power module 1, battery 2, roller blind drive mechanism 3 and master control module 4 are all arranged on the housing 6; the pull-cord adjustment mechanism 5 includes a reset switch 51, a sliding contact 52, a pull cord 53, and an elastic reset member 54. The reset switch 51 is arranged on the housing 6, and the reset switch 51 is electrically connected to the master control module 4. The sliding contact 52 is slidingly arranged on the housing 6. One end of the pull cord 53 is connected to the sliding contact 52, and the sliding contact 52 can trigger the reset switch 51 when pulled by the pull cord 53. The other end of the pull cord 53 is suspended below the housing 6. The elastic reset member 54 is arranged on the housing 6, and the sliding contact 52 can be elastically pushed away from the reset switch 51 by the elastic reset member 54. Such a pull-cord adjustment mechanism 5 is very simple and reliable, which is not only convenient for manufacturing, but also can accurately and stably trigger the reset switch 51 by pulling the pull-cord 53, thereby helping to further improve the reliability and applicability of the pull-cord control system.

[0028] like Figure 6 and Figure 8 As shown, the housing 6 is provided with a protruding piece 62, which encloses a vertical guide groove 61. The sliding contact 52 can be vertically slidably inserted into the vertical guide groove 61. This allows the vertical guide groove 61 to accurately and stably limit and guide the sliding contact 52, thereby helping to improve the stability and accuracy of the movement of the sliding contact 52. The provision of the protruding piece 62 not only does not weaken the structural strength of the housing 6, but also ensures that the vertical guide groove 61 has a very stable and reliable limiting effect on the sliding contact 52, thereby further helping to further improve the reliability and applicability of the roller blind.

[0029] like Figure 8 As shown, the protruding piece 62 encloses an inverted U-shaped protruding piece. The opening of the inverted U-shaped protruding piece can face downward, which can provide installation space for the pull cord using the opening, thereby eliminating the need to make the sliding contact block 52 too large, thereby facilitating the manufacture of a compact roller blind.

[0030] like Figures 6 to 9As shown, the reset switch 51 is a micro detection switch; the protruding piece 62 is provided with a clearance notch 621; the sliding contact block 52 includes a sliding portion 521 and a triggering portion 522. The sliding portion 521 is slidably mounted in the vertical guide groove 61, and the triggering portion 522 is disposed on the side wall of the sliding portion 521. The triggering portion 522 is positioned outside the protruding piece 62 through the clearance notch 621, and can trigger the micro detection switch as the sliding portion 521 slides. This not only makes the structure very compact, but also enables accurate and stable triggering of the reset switch 51, thereby effectively improving the accuracy and stability of the triggering, thereby further enhancing the reliability and applicability of the roller blind.

[0031] like Figures 6 to 9 As shown, at least one vertical guide groove 611 is formed on the groove wall of the vertical guide groove 61, and the sliding contact block 52 is provided with protrusions 523 equal in number to the vertical guide grooves 611 and corresponding in position to each other. The protrusions 523 are slidably fitted into the vertical guide grooves 611. The cooperation between the vertical guide grooves 611 and the protrusions 523 not only further improves the accuracy and stability of the installation and positioning of the sliding contact block 52, but also further improves the accuracy and stability of the sliding movement of the sliding contact block 52, thereby helping to further improve the reliability and applicability of the roller blind.

[0032] like Figures 6 to 9 As shown, the elastic reset member 54 is a spring. The housing 6 is provided with a supporting protrusion 63, and the sliding contact block 52 is provided with a cover groove 524. The upper groove wall of the cover groove 524 is provided with a boss portion 525. The elastic reset member 54 is vertically arranged on the top of the supporting protrusion 63. The cover groove 524 covers the supporting protrusion 63, and the upper end of the elastic reset member 54 is sleeved on the boss portion 525. The use of a spring not only makes the elastic reset member 54 have a simple structure, but also conveniently achieves the effect of elastic reset. The above assembly structure not only achieves an extremely compact structure, but also enables the elastic reset member 54 to accurately and stably exert a reliable elastic reset effect, thereby helping to further improve the reliability and applicability of the roller blind.

[0033] like Figures 6 to 8 As shown, a limiting groove 631 is provided on the top surface of the supporting protrusion 63, and the lower end of the elastic reset member 54 is placed in the limiting groove 631, so that the lower end of the elastic reset member 54 can be accurately and stably limited, so that the elastic reset member 54 can more accurately and stably play the role of elastic reset, which helps to further improve the accuracy and stability of the movement of the sliding contact block 52.

[0034] like Figure 6 、 Figure 7 and Figure 9As shown, the sliding contact block 52 is provided with a hanging ring portion 526, to which the pull cord 53 is connected; the lower end of the pull cord 53 is a rope loop end 531. The hanging ring portion 526 facilitates the stable connection of the pull cord 53 to the sliding contact block 52, thereby further improving the pulling stability and further enhancing the reliability and applicability of the roller blind. The rope loop end 531 can be used to attach a pull bead or a pull rod, making it convenient for different users to use it.

[0035] During the actual manufacturing process, the drawstring 53 can be exposed by only 15 cm, and other drawstrings or pull rods can be hung on the rope loop end 531 of the drawstring 53, so that users can choose according to their own needs.

[0036] like Figures 4 to 6 、 Figure 8 As shown, the housing 6 includes a body 64 and an end cover 65. A mounting slot 641 is defined on the end surface of the body 64. The reset switch 51 is positioned within the mounting slot 641. The sliding contact 52 and elastic reset member 54 are positioned on the inner wall of the end cover. A clearance hole 651 extends through the bottom of the end cover 65, allowing the pull cord 53 to pass downward through the clearance hole 651. The end cover 65 is mounted over the notch of the mounting slot 641. This not only conceals and protects the pull cord adjustment mechanism 5 but also facilitates inspection and maintenance of the sliding contact 52 and elastic reset member 54. Furthermore, the mounting slot 641 provides a means for mounting the master control module 4, facilitating electrical connection between the reset switch 51 and the master control module 4, thereby improving ease of manufacture and assembly. Furthermore, this keeps the pull cord 53 away from the curtain fabric, significantly reducing the risk of the pull cord 53 becoming entangled in the curtain fabric during use.

[0037] The master control module 4 utilizes a single-chip microcomputer (MCU) control unit, enabling stable and reliable control, thereby better meeting practical application requirements. When the reset switch 51 is triggered, an electrical signal is sent to the master control module 4. Upon receiving the signal, the master control module 4 activates the roller blind drive mechanism 3. Specifically, the control can be performed as follows: pulling the cord once opens the roller blind, pulling it again stops it, and pulling it again closes it. This cycle of control is repeated, and a single reset switch 51 is sufficient to achieve all three functions.

[0038] like Figures 1 to 3As shown, the master control module 4 is electrically connected to a 2.4GHz transceiver 7, an indicator light 8, a buzzer 9, and a button 10. The 2.4GHz transceiver 7 enables network connection requirements; the button 10 enables network configuration, remote control pairing, and factory reset operations; the indicator light 8 indicates network configuration status and remote control pairing status. The indicator light 8 primarily displays when the remote control is being paired and also flashes when the network configuration state is established; the buzzer 9 provides a low-battery reminder, indicating a battery level below 25%. This not only meets a variety of usage requirements but also facilitates user configuration operations, thereby further improving the applicability of the cord-operated control system.

[0039] When operating button 10, short press it to enter the network configuration module; press and hold it for 2 seconds to pair the remote controller; press and hold it for 10 seconds to restore the factory settings. This can meet the actual operation needs.

[0040] like Figure 1 and Figure 2 As shown, the master control module 4 is connected to a smart module 20, which may be a Tuya module or / and a Mijia module. Setting the smart module 20 can achieve the purpose of intelligent control, thereby being able to meet more diverse usage requirements.

[0041] like Figure 1 and Figure 2 As shown, the roller blind drive mechanism 3 includes a motor drive module 31 and a motor 32. The motor drive module 31 is electrically connected to the battery 2 and the master control module 4, respectively, and the motor 32 is electrically connected to the motor drive module 31. Such a roller blind drive mechanism 3 is very stable and reliable, which can reliably meet the driving requirements of the roller blind, thereby helping to further improve the reliability and applicability of the rope-type control system.

[0042] The motor 32 can be a DC brushed motor. The output end of the motor 32 is connected to a roller blind shaft (not shown in the figure). The roller blind shaft is provided with a roller blind cloth. The roller blind cloth can be rolled up through the roller blind shaft, which can well meet the needs of actual use.

[0043] like Figure 1 As shown, the power module 1 includes a Type-C power input interface 11, a DC-DC boost circuit 12, a power switch 13, and a voltage regulator 14 connected in series. The battery 2 is electrically connected between the output of the DC-DC boost circuit 12 and the input of the power switch 13. The master control module 4 is electrically connected to the output of the voltage regulator 14. This allows the power module 1 to have higher performance and charging performance when used with a DC5V adapter, thereby further improving the reliability and applicability of the cord-type control system.

[0044] In the actual manufacturing process, the master control module 4 adopts Figure 3 As shown; make the button 10 use Figure 3 The circuit structure shown; the reset switch 51 adopts Figure 3 The circuit structure shown; the indicator light 8 adopts Figure 3 The circuit structure shown in FIG. 1 can well meet the needs of actual manufacturing and use.

[0045] The above embodiments are preferred embodiments of the present invention. All structures similar to those of the present invention and equivalent changes made thereto should fall within the protection scope of the present invention.
