Detailed Implementation

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention. Therefore, they only show the components, orientations, and references (e.g., up, down, left, right, etc.) relevant to the present invention and are intended only to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be restrictive, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0019] like Figures 1-10 As shown, a splicing smart curtain power supply unit is installed at the end of the power track 2 and used to supply power to it. The power supply unit includes a main unit body 1, which has a slot 101 for the power track 2 to be inserted longitudinally. The main unit body 1 and the power track 2 are provided with a lateral (i.e., along the length direction of the power track 2) locking structure and a longitudinal locking structure to lock the two. The lateral locking structure includes a limiting groove 102 formed by the recess in the groove wall of the slot 101. The limiting groove 102 is used to engage the limiting part 202 formed by the protrusion at the end of the power rail 2 and restrict its lateral disengagement. The limiting part 202 is formed by the power rail 2 protruding along its width direction. The number can be one or two. Preferably, there are two limiting parts 202 and two limiting grooves 102. The two limiting parts 202 correspond one-to-one with the two limiting grooves 102, and each limiting part 202 is engaged in its corresponding limiting groove 102. The longitudinal locking structure includes a locking seat 113 protruding from the bottom of the slot 101. The locking seat 113 allows the elastic locking hook 201 on the power rail 2 to pass over and hook onto it to prevent the main unit housing 1 from longitudinally disengaging from the power rail 2. The elastic locking hook 201 has a guide surface and a locking surface. The guide surface is inclined so that the elastic locking hook 201 passes over the locking seat 113, and the locking surface locks the locking seat 113 to prevent its longitudinal disengagement. It is easy to install and replace, and is simple and reliable.

[0020] During assembly, first align the slot of slot 101 with the end of power rail 2, then push the main unit chassis 1 upwards. The limiting part 202 of power rail 2 gradually enters the limiting slot 102 of main unit chassis 1 to limit the lateral displacement of main unit chassis 1. During this process, the elastic locking hook 201 gradually enters slot 101 and passes over locking seat 113 to limit the longitudinal displacement of main unit chassis 1. This application utilizes slot 101 on main unit chassis 1 for power rail 2 to be inserted to form a plug-in fit between the two, and uses a lateral locking structure and a longitudinal locking mechanism to lock main unit chassis 1 and power rail 2. No special tools are required during installation and disassembly, making the operation simple and efficient. At the same time, the cooperation between limiting slot 102 and limiting part 202 can position the plug-in movement of the two, thereby improving the assembly accuracy of the two.

[0021] In some examples, the slot 101 has a protruding track transition bridge 103 for docking with the main rail in the power track 2. The track transition bridge 103 is equivalent to an extension rail, which extends the track length, thereby increasing the movement of the curtain. The curtain can move to both ends, preventing light leakage and making the curtain pleats even and beautiful. At the same time, it can prevent the hanging rollers from slipping off.

[0022] In some examples, the main unit housing 1 is adjustablely equipped with movable hanging lugs 3 along its length. The movable hanging lugs 3 have hanging holes for hanging curtains. The position of the movable hanging lugs 3 can be finely adjusted so that the curtains can be moved to both ends to prevent light leakage.

[0023] In some examples, the main unit housing 1 has a sliding groove 104 for the movable lifting lug 3 to slide and confine it inside, and one of the grooves is provided with an elastic protrusion 105, while the other is recessed to form an embedding groove 301 for the elastic protrusion 105 to be inserted. In this embodiment, the elastic protrusion 105 is located on the groove wall of the sliding groove 104, and the embedding groove 301 is located on the movable lifting lug 3. There are multiple embedding grooves 301, which are distributed at intervals. After the elastic protrusion 105 is inserted into the embedding groove 301 at different positions, the movable lifting lug 3 can be positioned at different positions. The elastic protrusion 105 can be, but is not limited to, a square, cylindrical or spherical structure.

[0024] The movable lifting lug 3 has two symmetrically arranged ribs 302 protruding longitudinally, and multiple embedding grooves 301 are distributed on the two ribs 302 to cooperate with two symmetrically arranged elastic protrusions 105 to form two sets of positioning structures.

[0025] In some examples, both sides of the slide 104 protrude towards each other to form a retaining edge 106 for confining the movable lifting lug 3 within the slide 104 and restricting its longitudinal disengagement. The elastic buckle 105 is located at the end of the retaining edge 106, and the retaining edge 106 has an elastic deformation groove 107 that allows the elastic buckle 105 to deform. The elastic deformation groove 107 extends through the end of the retaining edge 106 to form a U-shaped or V-shaped structure.

[0026] In some examples, the main unit housing 1 includes a lower cover 108 and an upper housing 109 that are snap-fitted together. One of the two has a buckle 110 protruding outwards, and the other has a groove 111 recessed outwards for the buckle 110 to be snapped into. There are multiple buckles 110 and grooves 111, and they correspond one-to-one. Each buckle 110 is snapped into its corresponding groove 111, and each buckle 110 has a beveled surface to guide it into the groove 111. The snap-fitted lower cover 108 and upper housing 109 replace the bolt connection in the prior art, which is convenient to operate and more aesthetically pleasing. A receiving cavity is formed between the lower cover 108 and the upper housing 109.

[0027] In some examples, a positioning post 112 protrudes from one of the slot 101 and the power rail 2, and a positioning groove is formed on the other for the positioning post 112 to engage. In this embodiment, the positioning post 112 is located inside the slot 101, and the positioning groove is located on the power rail 2. The positioning post 112 engaging in the positioning groove can prevent the main unit chassis 1 from laterally disengaging from the power rail 2. The positioning post 112 and the limiting groove 102 are located at both ends of the slot 101 along its length, thereby improving the connection strength between the power rail 2 and the main unit chassis 1.

[0028] In some examples, the main control board 4, voice module 5, Bluetooth Wi-Fi module 6, USB communication interface 7 and power module are installed in the receiving slot of the main unit housing 1. The power module provides power to each module and the curtain traction device for various operations. The voice module 5 includes a speaker or microphone, etc.

[0029] In some examples, the power module is an AC power supply 8 or a DC power supply 9. Different voltage levels of power supplies can be replaced for different users and according to different countries and regions to meet different needs. The DC power supply 9 can be, but is not limited to, a lithium battery pack.

[0030] In some examples, the main unit housing 1 is equipped with a main unit contact spring 11 for contacting the track contact spring 10 on the power rail 2. The main unit contact spring 11 is a stationary spring, and the track contact spring 10 is an elastic spring. Both are made of materials with good conductivity. After the main unit housing 1 and the power rail 2 are assembled, the track contact spring 10 on the power rail 2 is tightly connected to the main unit contact spring 11 in the main unit housing 1 due to the elastic effect. The main unit housing provides current to the power rail 2 to supply power to it.

[0031] Working principle: During assembly, first align the slot of slot 101 with the end of power rail 2, then push the main unit 1 upwards. The limiting part 202 of power rail 2 gradually enters the limiting slot 102 of main unit 1 to limit the lateral displacement of the main unit. During the process, the elastic locking hook 201 gradually enters slot 101 and passes over locking seat 113 to limit the longitudinal displacement of main unit 1. Finally, the positioning post 112 is inserted into the positioning slot to further lock the main unit 1 and power rail 2 laterally. After the main unit 1 and power rail 2 are assembled, the rail contact spring 10 and the main unit contact spring 11 are tightly connected to supply power to power rail 2.

[0032] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
