For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0050] This utility model discloses a multi-track connection structure for a curtain machine, including at least two guide rails 1 and an electrical connection assembly 4 for connecting the two guide rails 1.

[0051] The guide rail 1 is provided with conductive strips 2 arranged along its length. Generally, two conductive strips 2 are provided, with the positive and negative terminals respectively connected to the two conductive strips 2. By switching the polarity of the electricity connected to the two conductive strips 2, the moving body 3 can reciprocate on the guide rail 1. The conductive strips 2 can be made of metal, metal-plastic composite materials, or other conductive materials, such as copper strips.

[0052] The electrical connection assembly 4 includes a first connection part 42a, a second connection part 42b, and an intermediate connection part 41. The intermediate connection part 41 enables the first connection part 42a and the second connection part 42b to form an electrical connection. The first connection part 42a forms an electrical connection with a conductive strip 2 in one guide rail 1, and the second connection part 42b forms an electrical connection with a conductive strip 2 in another guide rail 1.

[0053] In applications, for example, for windows located at corners, it is originally necessary to install complete curtain machines on two separate walls. However, the multi-track connection structure of this utility model connects the conductive strips 2 in multiple guide rails 1 together and uses an electrical control system (not shown) to power multiple guide rails 1 and control electrode switching. This eliminates the need for a one-to-one correspondence between guide rails 1 and electrical control system, reducing costs and structural complexity.

[0054] The specific connection mode of the guide rail 1 and the electrical connection assembly 4 is further introduced through multiple embodiments as follows:

[0055] Embodiment 1

[0056] As Figure 3 and Figure 4 In the embodiment one, the guide rail 1 is provided with the socket 11, and the socket 11 is in electrical connection with the conductive strip 2 inside the guide rail 1; the first connecting part 42a and the second connecting part 42b of the electrical connection assembly 4 are both plugs, and the intermediate connecting part 41 is a wire, and the plug is plugged with the socket 11.

[0057] In this embodiment, the first connecting part 42a, the second connecting part 42b and the intermediate connecting part 41 are an integral device, specifically a cable with plugs at both ends; the connection operation of the first connecting part 42a, the second connecting part 42b and the socket 11 is convenient, and the electrical connection of the two guide rails 1 can be quickly realized, in addition, the intermediate connecting part 41 composed of the wire has higher adaptability to space, for example, if there is an obstacle between the two guide rails 1, the soft intermediate connecting part 41 can adaptively adjust its position and form.

[0058] It should be understood that the guide rail 1 in this embodiment is provided with two conductive strips 2, which are defined as the first conductive strip and the second conductive strip for convenience of description, when the two guide rails 1 are connected through the electrical connection assembly 4, the first conductive strip in one guide rail 1 is in electrical connection with the first conductive strip in the other guide rail 1, and the second conductive strip in one guide rail 1 is in electrical connection with the second conductive strip in the other guide rail 1.

[0059] In addition, as Figure 5 shown, the number of guide rails 1 can be more, and the angle between the two guide rails 1 is not limited to 90 degrees.

[0060] Embodiment 2

[0061] As Figures 6-11 shown, in the embodiment two, the intermediate connecting part 41 includes a bridging rail 411, and the bridging rail 411 is provided with a bridging conductive strip 412, wherein the bridging conductive strip 412 can be made of the same material as the conductive strip 2.

[0062] The two ends of the bridging rail 411 are respectively connected with two guide rails 1, as Figure 6 and Figure 7As shown, the connection between the connecting rail 411 and the guide rail 1 can be achieved by using a guide rail connecting piece 100. In brief, a channel is formed in the guide rail connecting piece 100, the end portions of the connecting rail 411 and the guide rail 1 are inserted into the channel of the guide rail connecting piece 100, and then a locking screw is screwed into the guide rail connecting piece 100 to fix the positions of the connecting rail 411 and the guide rail 1, thereby completing the connection. It should be noted that in the existing electric curtain machine, the guide rail 1 is commonly connected, for example, in the prior art CN221635512U, CN117958585A, CN219895328U, etc., and thus the specific structure of the guide rail connecting piece 100 and the connection principle will not be described herein. In addition, the present application does not limit the connection mode between the connecting rail 411 and the guide rail 1, and the connection between the connecting rail 411 and the guide rail 1 can be achieved.

[0063] In the embodiment, the first connecting portion 42a and the second connecting portion 42b each include a conductive connecting piece 421, one part of the conductive connecting piece 421 is in contact with the conductive strip 2 in the guide rail 1, and the other part of the conductive connecting piece 421 is in contact with the connecting conductive strip 412 in the connecting rail 411. The conductive connecting piece 421 is made of a conductive material, such as a copper strip. The conductive connecting piece 421 is in contact with the connecting conductive strip 412 and the conductive strip 2, respectively, to achieve electrical connection between the connecting conductive strip 412 and the conductive strip 2, and further to achieve electrical connection between the two conductive strips 2 in the two guide rails 1.

[0064] Specifically, to ensure that the conductive connecting piece 421 can stably abut against the connecting conductive strip 412 and the conductive strip 2, the electrical connection assembly 4 further includes a first pressing piece 423 and a second pressing piece 424. One part of the conductive connecting piece 421 is pressed by the first pressing piece 423 to abut against the conductive strip 2 in the guide rail 1, and the other part of the conductive connecting piece 421 is pressed by the second pressing piece 424 to abut against the connecting conductive strip 412 in the connecting rail 411.

[0065] More specifically, as shown in Figures 9-11 The first connecting portion 42a and the second connecting portion 42b further include a mounting seat 422, which is arranged between the guide rail 1 and the connecting rail 411. The conductive connecting piece 421 is a long strip-shaped metal sheet, and both ends of the conductive connecting piece 421 are connected to the mounting seat 422. The first pressing piece 423 and the second pressing piece 424 are both screws, which are screwed onto the mounting seat 422. One end of the screw presses the conductive connecting piece 421, so that the conductive connecting piece 421 is tightly pressed against the conductive strip 2 and the connecting conductive strip 412.

[0066] In the embodiment, the first connecting portion 42a and the second connecting portion 42b each include a conductive connecting piece 421, one part of the conductive connecting piece 421 is in contact with the conductive strip 2 in the guide rail 1, and the other part of the conductive connecting piece 421 is in contact with the connecting conductive strip 412 in the connecting rail 411. The conductive connecting piece 421 is made of a conductive material, such as a copper strip. The conductive connecting piece 421 is in contact with the connecting conductive strip 412 and the conductive strip 2, respectively, to achieve electrical connection between the connecting conductive strip 412 and the conductive strip 2, and further to achieve electrical connection between the two conductive strips 2 in the two guide rails 1. Figure 11As shown, the mounting seat 422 is slidingly arranged in the guide rail 1, the internal structure of the bridging rail 411 is the same as that of the guide rail 1, and a part of the mounting seat 422 is located in the guide rail and another part is located in the bridging rail 411. When the first pressing member 423 and the second pressing member 424 are tightened, the position of the mounting seat 422 can be fixed.

[0067] In this embodiment, the screw pressing mode can ensure that the conductive bridging member 421 and the conductive strip 2 and the conductive bridging member 421 and the bridging conductive strip 412 have a large pressing force therebetween, so that the connection is stable and not easy to separate due to external force pulling. The first pressing member 423 and the second pressing member 424 can be provided with multiple members respectively.

[0068] In the second embodiment, the overall strength of the curtain machine is improved, and the bridging position between the two rails still has a rail structure, which is more aesthetic.

[0069] Embodiment 3

[0070] As shown in Figure 6 and Figures 12-14 In the third embodiment, the intermediate connecting part 41 still adopts the form of the bridging rail 411. The difference between the third embodiment and the second embodiment is that the two ends of the bridging conductive strip 412 in the third embodiment extend from the end of the bridging rail 411 and form the first connecting part 42a and the second connecting part 42b, while the intermediate connecting part 41, the first connecting part 42a and the second connecting part 42b in the second embodiment are in a split structure.

[0071] Meanwhile, in the third embodiment, the end of the guide rail 1 forms a socket 12, the conductive strip 2 is located on the side of the socket 12, the first connecting part 42a / second connecting part 42b is inserted into the socket 12, and the first connecting part 42a and the second connecting part 42b are configured to abut against the conductive strip 2 under the action of elastic force.

[0072] The elastic force received by the first connecting part 42a and the second connecting part 42b can come from the elastic force of the first connecting part 42a and the second connecting part 42b themselves.

[0073] Specifically, as shown in Figure 13As shown, the butt joint conductive strip 412 is a long strip-shaped metal strip, the first connecting part 42a and the second connecting part 42b each include a bending section 425 formed by bending the end of the butt joint conductive strip 412, and an elastic expansion and contraction space 426 is formed between the bending section 425 and the body of the butt joint conductive strip 412. The width of the first connecting part 42a and the second connecting part 42b in a natural state should be greater than the width of the socket 12, and when the first connecting part 42a / second connecting part 42b is inserted into the socket 12, the elastic expansion and contraction space 426 on the first connecting part 42a / second connecting part 42b is compressed, so that the first connecting part 42a / second connecting part 42b has a restoring tendency and is pressed against the conductive strip 2.

[0074] In the embodiment, the first connecting part 42a and the second connecting part 42b can be connected to the end of the guide rail 1 in a plug-in manner, which is simple to operate. Of course, the structure connection stability between the butt joint rail 411 and the guide rail 1 can still be enhanced by the guide rail butt joint piece 100.

[0075] Embodiment 4

[0076] As shown, the structure principle of Embodiment Four is basically the same as that of Embodiment Three, and the difference lies in that the elastic force borne by the first connecting part 42a and the second connecting part 42b in Embodiment Three comes from the elastic force of the first connecting part 42a and the second connecting part 42b themselves, while the elastic force borne by the first connecting part 42a and the second connecting part 42b in Embodiment Four comes from external parts. Figure 15

[0077] Specifically, the butt joint conductive strip 412 is a long strip-shaped metal strip, and the first connecting part 42a and the second connecting part 42b include elastic members arranged at the ends of the butt joint conductive strip 412. In the embodiment, the elastic members are elastic rubber blocks 427, which can be fixed to the ends of the butt joint conductive strip 412.

[0078] When the butt joint conductive strip 412 is made of a conductive material with weak elasticity, the structure of Embodiment Four is more suitable. In addition, the elasticity is provided by external parts, and when the parts are aged and the elasticity is weakened, only the parts (elastic rubber blocks 427) need to be replaced, without replacing the butt joint conductive strip 412.

[0079] In summary, the window curtain machine multi-rail connection structure provided by the utility model can realize electrical connection between multiple guide rails 1, so that the multiple guide rails 1 can be powered and controlled by only one electrical control system, thereby reducing the cost and structural complexity.

[0080] 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 related description of other embodiments. In summary, the window curtain machine multi-rail connection structure provided by the utility model can realize electrical connection between multiple guide rails 1, so that the multiple guide rails 1 can be powered and controlled by only one electrical control system, thereby reducing the cost and structural complexity.

[0081] The above merely describes preferred embodiments of the present application, and it should be noted that, for those skilled in the art, without departing from the technical principles of the present application, a number of improvements and replacements can be made, and these improvements and replacements should also be considered as the protection scope of the present application.
