[0043] AsFigures 1-4 The utility model discloses an embodiment shows a kind of curtain 500 machine that can realize stroke positioning, including guide rail 1, at least two positioning members 3 and at least one mobile body 2;

[0044] The guide rail 1 is equipped with electrically conductive strip 11 and transmission strip 12 along its length direction, the electrically conductive strip 11 is equipped with two, two electrically conductive strips 11 are configured to be connected into different polarity electricity;The positioning member 3 is arranged in the guide rail 1;The mobile body 2 is arranged in the guide rail 1 and is located between two positioning members 3, and the mobile body 2 is equipped with electrically conductive contact piece 21, transmission wheel 22 and motor 23 for driving the rotation of transmission wheel 22, the electrically conductive contact piece 21 is electrically connected with the motor 23, and the electrically conductive contact piece 21 is abutted with the electrically conductive strip 11 to realize electrical connection;Transmission wheel 22 is transmissionally connected with transmission strip 12;The mobile body 2 is equipped with first detection unit 24 and second detection unit 25, the first detection unit 24 is triggered by the positioning member 3 at one end of the mobile body 2, and the second detection unit 25 is triggered by the positioning member 3 at the other end of the mobile body 2.

[0045] Wherein, the electrically conductive strip 11 is connected with electric control system, and electric control system is used for power supply for two electrically conductive strips 11 and switches the polarity of electricity on two electrically conductive strips 11.Specifically, when electrically conductive contact piece 21 contacts with electrically conductive strip 11, electrically conductive contact piece 21 can conduct electricity on electrically conductive strip 11 to motor 23;When two electrically conductive strips 11 are connected into different polarity electricity respectively, for example, one electrically conductive strip 11 is positive, and the other is negative, and motor 23 drives transmission wheel 22 to positively rotate;If the polarity of two electrically conductive strips 11 is exchanged, then motor 23 drives transmission wheel 22 to reverse;When transmission wheel 22 rotates, transmission wheel 22 moves along the length direction of transmission belt, and when transmission wheel 22 positively rotates, it can drive mobile body 2 to move along guide rail 1 in one direction;When transmission wheel 22 reverses, it can drive mobile body 2 to move along guide rail 1 in another direction.Such, realize the reciprocating movement of mobile body 2 in track.

[0046] Wherein, transmission strip 12 can be rack, synchronous belt and the like structure.

[0047] In the above scheme, the mobile body 2 on guide rail 1 can be provided with one, two or even more, and one mobile body 2 corresponds to a window curtain 500;Guide rail 1 is provided with multiple curtain hangers 4, such as Figure 3As shown, the curtain 500 is hung on the curtain hanger 4 and a movable body 2. Among the curtain hangers 4 corresponding to a curtain 500, the curtain hanger 4 located at the outermost edge is fixed in position, while the other curtain hangers 4 can move along the guide rail 1. When the movable body 2 moves away from the outermost curtain hanger 4, the movable body 2 causes the curtain 500 to open; when the movable body 2 moves closer to the outermost curtain hanger 4, the movable body 2 pushes the multiple movable curtain hangers 4 closer to each other, causing the curtain 500 to close.

[0048] In this embodiment, by providing a positioning element 3 within the guide rail 1, the travel distance of the moving body 2 can be limited; for example... Figure 3 As shown, when the moving body 2 approaches a positioning element 3 in one direction to a certain distance, the first detection unit 24 is triggered, and the moving body 2 stops moving; when the moving body 2 approaches another positioning element 3 in another direction to a certain distance, the second detection unit 25 is triggered, and the moving body 2 stops moving. This allows for more diverse applications of the curtain 500 machine; for example… Figure 9 As shown, three windows 600 are shown, and three curtains 500 are set on a guide rail 1. The stroke of the moving body 2 is limited by the positioning component 3, so that one curtain 500 machine can realize the opening and closing drive of the curtains 500 on the three windows 600.

[0049] Furthermore, the opening and closing range of the curtains on track 1 can be different; for example... Figure 10 As shown, by setting the position of the positioning component 3 within the guide rail 1, the opening and closing ranges of the two curtains 500 can be different, allowing one curtain 500 to have a larger opening and closing range and the other curtain 500 to have a smaller opening and closing range.

[0050] Thus, the curtain 500 machine, which can achieve stroke positioning, can control the opening and closing of multiple curtains 500, and can also differentiate the opening and closing range of different curtains 500, which can meet more application needs and make the arrangement of the curtain 500 machine more flexible.

[0051] The position of the positioning element 3 within the guide rail 1 can be designed during factory manufacturing.

[0052] In some embodiments, to further improve the flexibility of the curtain 500 machine's layout, the positioning element 3 is detachably connected to the guide rail 1, so as to adjust the position of the positioning element 3 within the guide rail 1. In other words, the position of the positioning element 3 can be adjusted at any time as needed, thereby adjusting the opening and closing range of the curtain 500.

[0053] Specifically, such as Figure 5As shown, the positioning member 3 is in sliding fit with the guide rail 1, and a clamping screw 31 is threadedly connected to the positioning member 3, one end of the clamping screw 31 being in extrusion fit with the guide rail 1 to fix the position of the positioning member 3 in the guide rail 1. Here, the extrusion fit refers to the interaction force between the clamping screw 31 and the guide rail 1, and the clamping screw 31 and the guide rail 1 can be in direct contact or indirect contact. When the position of the positioning member 3 needs to be adjusted, the clamping screw 31 can be loosened, and then the positioning member 3 is moved, and after the position of the positioning member 3 is determined, the clamping screw 31 is tightened again to form the extrusion fit with the guide rail 1.

[0054] To avoid the window curtain hanger 4 from hindering the position adjustment of the positioning member 3, the preferred solution is that Figure 5 As shown, the guide rail 1 includes a first space la and a second space lb divided along its cross section, the positioning member 3 is located in the first space la, and the window curtain hanger 4 is slidingly arranged in the second space lb. In this way, the positioning member 3 is in the first space la, and the window curtain hanger 4 is in the second space lb, and the positioning member 3 and the window curtain hanger 4 do not interfere with each other. Here, from the perspective of Figure 5 the first space la and the second space lb can be distributed in the up-down direction or the left-right direction, as long as the positioning member 3 does not block the moving path of the window curtain hanger 4, and the window curtain hanger 4 does not block the moving path of the positioning member 3.

[0055] In the above solution, the first detection unit 24 and the second detection unit 25 are in signal trigger connection or mechanical trigger connection with the positioning member 3, for example:

[0056] In an embodiment, as shown in Figure 4 the first detection unit 24 (not labeled in the figure) and the second detection unit 25 (not labeled in the figure) are both Hall elements, and the positioning member 3 is provided with a magnetic member 32 for the Hall elements to sense, or the positioning member 3 itself is a magnetic member 32. In this embodiment, the first detection unit 24 and the second detection unit 25 can be respectively arranged at both ends of the moving direction of the moving body 2. When the first detection unit 24 / second detection unit 25 approaches the positioning member 3 to a certain distance, the first detection unit 24 / second detection unit 25 (Hall element) senses the change of the magnetic field and is triggered, that is, the first detection unit 24 / second detection unit 25 is in signal trigger with the positioning member 3.

[0057] In another embodiment, as shown in Figure 7 and Figure 8As shown, the first detection unit 24 and the second detection unit 25 are limit switches. In this embodiment, the first detection unit 24 / second detection unit 25 (limit switches) is mechanically triggered by the positioning member 3, and the positioning member 3 can directly or indirectly contact the first detection unit 24 / second detection unit 25.

[0058] Furthermore, such as Figure 8 As shown, the first detection unit 24 and the second detection unit 25 are disposed inside the moving body 2. The moving body 2 is provided with a first mechanical trigger 26 and a second mechanical trigger 27. In this way, the first detection unit 24 and the second detection unit 25 are hidden inside the moving body 2, which is aesthetically pleasing and can be protected to a certain extent.

[0059] The first mechanical trigger 26 is slidably disposed on the movable body 2. The first mechanical trigger 26 includes a first abutting portion 261 protruding from one end of the movable body 2, and the first mechanical trigger 26 also includes a first pressing portion 262 located inside the movable body 2 to press the first detection unit 24. As the movable body 2 moves, the first abutting portion 261 contacts the positioning member 3, and the first mechanical trigger 26 is pushed, so that the first pressing portion 262 presses the first detection unit 24, thereby stopping the movable body from moving.

[0060] The second mechanical trigger 27 is slidably disposed on the movable body 2. The second mechanical trigger 27 includes a second abutting portion 271 protruding from the other end of the movable body 2, and the second mechanical trigger 27 also includes a second pressing portion 272 located inside the movable body 2 to press the second detection unit 25. The working principle of the second mechanical trigger 27 is the same as that of the first mechanical trigger 26.

[0061] In this embodiment, the first abutment 261 and the second abutment 271 are rod-shaped, and the moving body 2 is provided with guide holes for the first abutment 261 and the second abutment 271 to slide, so that the first mechanical trigger 26 and the second mechanical trigger 27 can move in a predetermined direction.

[0062] In addition, such as Figure 8As shown, the mobile body 2 is further provided with an elastic member 28, which is used to drive the first mechanical trigger 26 to move away from the first detection unit 24, and / or the elastic member 28 is used to drive the second mechanical trigger 27 to move away from the second detection unit 25. That is, the first detection unit 24 is reset by the elastic member 28, and the second detection unit 25 is reset by the elastic member 28; the first mechanical trigger 26 and the second mechanical trigger 27 can be driven by different elastic members 28 or by the same elastic member 28. In the embodiment, the elastic member 28 is a spring, and in other embodiments, an elastic structure such as a spring plate can also be used.

[0063] In the above embodiments, the description of each embodiment has its own focus, and the parts not described in detail in a certain embodiment can be referred to the relevant description of other embodiments.

[0064] The above only describes the preferred embodiments of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and substitutions can be made, and these improvements and substitutions should also be considered as the protection scope of the present application.
