Detailed Implementation

[0018] like Figures 1-4As shown, a hand-operated tubular motor travel head mechanism for raising and lowering curtains is disclosed. The travel head mechanism is connected to a motor assembly 1, which includes a gearbox, a motor, a control board, and other structures. The motor assembly 1 is existing technology and will not be described in detail. The travel head mechanism 2 includes a travel head 28, with an outer end cover 31 on the outside of the travel head 28. The outer end cover 31 is fixed to the travel head 28 by an outer end cover screw 32. A setting plate 30 is provided between the travel head 28 and the outer end cover 31 to cooperate with the operation of the motor assembly 1. The setting plate 30 can be equipped with a charging port, an indicator light, and buttons. It can charge the motor assembly 1, provide charging status feedback from the indicator light, set limit switches in conjunction with the pull cord 21, restore factory settings, and set various control modules on the setting plate 30 to achieve more functions. A pull cord hole 282 is provided inside the travel head 28, through which a pull cord 21 passes. A control mechanism connected to the pull cord 21 and electrically connected to the setting plate 30 is provided inside the travel head 28.

[0019] like Figure 2 , 3 As shown, the control mechanism includes a switch block 26 rotatably connected to the travel head 28. A pressure cap 24 is provided on the outside of the switch block 26 to fix the switch block 26 inside the travel head 28. A long-stroke switch 23 electrically connected to the setting plate 30 is fixed on the outside of the pressure cap 24. The long-stroke switch 23 includes a switch arm 231 that contacts the boss 266. The long-stroke switch 23 is fixed to the pressure cap 24 by a fixing screw 22.

[0020] The switch block 26 is cylindrical in shape. On one side of the switch block 26, there is a boss 266 that contacts the long-stroke switch 23. On the other side, there is a cylindrical platform 265. Inside the cylindrical platform 265, there is a pin hole 264 that coincides with the central axis of the switch block 26. A pin 25 passes through the pin hole 264. Inside the stroke head 28, there is a pin groove 281 for placing the pin 25. The switch block 26 has a wire groove 261 for winding the pull rope 21 and a wire buckle groove 263 for knotting and fixing the pull rope 21. The switch block 26 also has a reset mechanism for resetting the switch block 26.

[0021] The reset mechanism includes a torsion spring 27 sleeved on the cylindrical platform 265. A first torsion spring groove 262 is provided on one side of the switch block 26, and a second torsion spring groove 283 is provided in the stroke head 28. The two ends of the torsion spring 27 are located in the first torsion spring groove 262 and the second torsion spring groove 283.

[0022] When in use, when the pull cord 21 is not pulled, the boss 266 and the switch arm 231 of the long-stroke switch 23 are not in contact. When the pull cord 21 is pulled down, the switch block 26 rotates around the pin 25, the boss 266 touches the switch arm 231, compressing the switch arm 231. At the same time, the torsion spring 27 is compressed, and the long-stroke switch 23 is internally connected to send a control signal to the internal control board of the motor assembly 1. This results in the motor assembly 1 moving upwards when pulled briefly, stopping when pulled briefly again, and stopping when pulled again. When the hand is released, the torsion spring 27 rebounds, causing the switch block 26 to reverse, the boss 266 to disengage from the switch arm 231, and the long-stroke switch 23 returns to its normal state.

[0023] The above specific embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
