[0057] 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 relevant to the present invention. Orientations and references (e.g., up, down, left, right, etc.) are only used 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.

[0058] like Figure 1 As shown, a segmented curtain track includes several track units 100 and a splicing structure located between two adjacent track units 100 to assemble them together, such as... Figure 18 As shown, each track unit 100 can be of equal or unequal length, that is, each track unit 100 can be of any length (such as 100cm, 50cm, 30cm, 20cm, 10cm or 5cm, etc.). Thus, curtain tracks of any length can be formed by splicing the structure to meet user needs. The curtain track is equipped with track mounting brackets 7 for fixing it, which can realize top mounting or side mounting, and multiple hanging rollers 8 for hanging curtains can be movably installed on it.

[0059] like Figure 11 As shown, each track unit 100 includes a side rail 1, a transmission rack 2 installed inside the side rail 1, a side positioning mechanism located between the transmission rack 2 and the side rail 1 to position the two, and a side locking mechanism for locking the two.

[0060] The transmission rack 2 has multiple teeth 208 along its length. The side rail 1 includes two opposing half rails 1a. The two half rails 1a have the same structure and are roughly "U" shaped. The two half rails enclose a mounting cavity for the transmission rack 2 to be installed.

[0061] The splicing structure includes a docking locking mechanism for locking two adjacent side rails 1 and a docking positioning mechanism for inserting and positioning two adjacent transmission racks 2.

[0062] like Figure 2 , Figures 7-10As shown, the docking locking mechanism includes a protruding insert 101 at one end of the side rail 1, an elastic latch 102 elastically disposed on the insert 101, a slot 103 located at the other end of the side rail 1 for inserting the insert 101, and a latching groove 117 recessed in the slot 103 for latching the latch 102; each half rail 1a includes an upper plate 111, a lower plate 112, and a side plate 113 for connecting the two to form the above-mentioned "U"-shaped structure, and the upper plate 111 protrudes towards the lower plate 112 to form an upper limit bar 114, the lower plate 112 protrudes towards the upper plate 111 to form a lower limit bar 115, and the upper limit bar 114... 14. The lower limit strip 115 and part of the side plate 113 enclose and form the above-mentioned slot 103. The upper limit strip 114 and the lower limit strip 115 form the groove wall of the slot 103. The part of the side plate 113 forms the groove bottom of the slot 103. The depth of the slot 103 matches the length of the insert 101. The groove width of the slot 103 is slightly larger than the thickness of the insert 101 to facilitate the insertion of the insert 101. The insertion end of the insert 101 is provided with a slope to guide its insertion into the slot 103. The groove bottom of the slot 103 is recessed to form the above-mentioned fastening groove 117. When the insert 101 is inserted into the slot 103, the latch 102 engages with the fastening groove 117 to fasten and lock the two adjacent half rails 1a.

[0063] One end of the latch 102 is fixed to the insert 101 as a fixed end 102a, and the other end is a suspended end 102b. The suspended end 102b protrudes towards the bottom of the slot 103 to achieve a snap-fit. The thickness of the suspended end 102b is greater than the thickness of the fixed end 102a to give it sufficient rigidity. In order to improve the locking effect, the suspended end 102b can be slightly bent towards the bottom of the slot.

[0064] During assembly, the transmission rack 2 and the side rail 1 corresponding to its length are first locked using the side locking mechanism to form a track unit 100. Then, multiple track units 100 are sequentially spliced ​​together to form a curtain track of a predetermined length, such as... Figure 16 As shown, during the splicing process, the insert 101 on one of the two adjacent half-tracks 1a is inserted into the slot 103 in the other half-track 1a. The latch 102 on the insert 101 engages with the snap-fit ​​groove 117 to lock the two adjacent half-tracks 1a. At the same time, the transmission rack 2 in the two adjacent side rails 1 is inserted and positioned by the docking positioning mechanism to complete the assembly. The transmission rack 2 and the side rail 1 form a normal manual curtain track. The transmission rack 2, the side rail 1 and the sliding contact line 3 can form an electric curtain track or a smart curtain track.

[0065] In some examples, such as Figure 3 and Figure 4As shown, the side-mounted locking mechanism has multiple components distributed at intervals along the length of the track unit 100. Each side-mounted locking mechanism includes an elastic locking hook 201 located on the transmission rack 2 and the side rail 1, respectively, and a locking groove 104 into which the elastic locking hook 201 engages. The multiple elastic locking hooks 201 and the multiple locking grooves 104 correspond one-to-one. In this embodiment, the elastic locking hook 201 is located on the transmission rack 2, and the locking groove 104 is located on the half rail 1a. During the assembly process of the transmission rack 2 and the half rail 1a, the elastic locking hook 201 is forced into the locking groove 104 by external force and hooks into the locking groove 104, thereby realizing the locking of the transmission rack 2 and the half rail 1a.

[0066] In some examples, such as Figure 3 and Figure 4 As shown, the side-mounted positioning mechanism includes positioning bosses 202 located at both ends of the transmission rack 2 and both ends of the side rail 1, and positioning grooves 105 for the positioning bosses 202 to be engaged. During the assembly process of the transmission rack 2 and the half rail 1a, the positioning bosses 202 and the positioning grooves 105 are first aligned. During the process of the two being inserted and positioned, the elastic locking hooks 201 and the locking grooves 104 lock synchronously.

[0067] In some examples, such as Figures 3-6 As shown, the side-mounted positioning mechanism further includes:

[0068] The first locking bar 203 extends from both sides of the transmission rack 2 along its width direction;

[0069] The first card slot 106 is located on the half rail 1a and its opening faces the first card strip 203 for insertion;

[0070] The second locking bar 107 extends from the half rail 1a toward the transmission rack 2;

[0071] The second slot 204 is located on the transmission rack 2 and its opening faces the second slot 107 for insertion.

[0072] While the first locking bar 203 is inserted into the first locking slot 106, the second locking bar 107 is also inserted into the second locking slot 204, forming a cross-lock. The first locking bar 203, the first locking slot 106, the second locking bar 107, and the second locking slot 204 all extend along the length of the track unit 100, ensuring that the transmission rack 2 and the side rail 1 are engaged throughout their entire length, thereby improving the connection strength between the two.

[0073] In some examples, such as Figures 12-15As shown, the track unit 100 also includes a sliding contact line 3 extending along its length and engaged within the transmission rack 2. The sliding contact line 3 and the corresponding transmission rack 2 are of equal length. The sliding contact line 3 includes a column 301 with a notch 303 and a flange 302 extending from the notch 303. The transmission rack 2 has a positioning strip 211 protruding towards the sliding contact line 3 for engaging the notch 303 to position the sliding contact line 3. The transmission rack 2 has a plurality of spaced pressure posts 209 along its length. A limiting groove 210 is formed between the pressure posts 209 and the transmission rack 2 for the flange 302 to engage. This fixes the sliding contact line 3, and the column 301 passes through the limiting groove 210 and makes conductive contact with the conductive part of the traction trolley 9. Ribs 212 connect multiple teeth 208. The ribs 212 improve the structural strength of the teeth 208 and form a raceway between the ribs 212 and the transmission rack 2 for the traction wheel of the traction trolley 9 to roll. The traction wheel can reciprocate along this raceway. Simultaneously, the drive gear of the traction trolley 9 meshes with the transmission rack 2, causing the traction trolley 9 to reciprocate along the length of the transmission rack 2. Cloth-hanging arms 901 are provided on both sides of the traction trolley 9 along its direction of movement. Figure 22 and Figure 23 As shown.

[0074] The splicing structure also includes stationary contacts 4 located at both ends of the sliding contact line 3 and movable contacts 5 that are elastically set and used for conductive contact with the stationary contacts 4. Both the stationary contacts 4 and the movable contacts 5 are pressed into the inner hole of the sliding contact line 3 to achieve a tight fit. The stationary contacts 4 do not protrude from the sliding contact line 3 and can be a solid structure or a hollow structure with one end blocked. When two adjacent transmission racks 2 are connected, the stationary contacts 4 and movable contacts 5 of the sliding contact lines 3 that are locked inside the two transmission racks 2 come into contact, and the two adjacent sliding contact lines 3 are connected to form an electric curtain track or an intelligent curtain track.

[0075] In some examples, such as Figure 18 and Figure 19 As shown, both ends of the curtain track are equipped with adjustable end caps 6. The end caps 6 can be finely adjusted along the length of the curtain track to achieve the function of adjusting the length of the curtain track. Specifically, the end caps 6 can be fitted onto the outside of the curtain track, and screws can be installed on the end caps 6. The screws pass through the end caps 6 and their heads abut against different positions along the length of the curtain track, which can fix the end caps 6 in different positions, thereby realizing the length adjustment of the curtain track.

[0076] In some examples, such as Figures 3-6As shown, the docking positioning mechanism includes a positioning protrusion 205 protruding from one end face of the transmission rack 2 and a groove 206 recessed in the other end face of the transmission rack 2 for the positioning protrusion 205 to be inserted. The positioning protrusion 205 and the groove 206 are arranged in corresponding shapes and numbers. The number can be, but is not limited to, one, two or three. The positioning protrusion 205 is preferably cylindrical, and the end of the positioning protrusion 205 facing away from the transmission rack 2 is tapered, which is more conducive to the insertion of the positioning protrusion 205 into the groove 206. In this embodiment, there are five positioning protrusions 205, which are arranged linearly. The cross-sectional area of ​​the positioning protrusion 205 located in the middle is larger than the cross-sectional area of ​​the other positioning protrusions 205.

[0077] In some examples, such as Figure 7 As shown, the docking locking mechanism also includes a separation hole 108 located on the side where the slot 103 is located and communicating with the slot 103 to push out the latch 102 that is engaged in the snap-fit ​​groove 117. When the curtain track needs to be disassembled, a tool is used to extend into the snap-fit ​​groove 117 through the separation hole 108 to apply pressure to the elastic latch 102, so that the latch 102 and the snap-fit ​​groove 117 are separated and the latch 102 and the snap-fit ​​groove 117 are unlocked. At this time, the insert 101 can be separated from the slot 103.

[0078] In some examples, such as Figure 15 As shown, the transmission rack 2 is provided with a number of spaced protrusions 207 along its length direction. The number of protrusions 207 and the transmission rack 2 form the second groove 204. The transmission rack 2 forms one side of the groove wall of the second groove 204, and the number of protrusions 207 are arranged side by side to form the other side of the groove wall of the second groove 204. The spaced protrusions 207 can leave a position for the latch 102, and also facilitate the insertion of the second latch 107.

[0079] like Figure 7 and Figure 8 As shown, one end of the half-rail 1a protrudes along its length to form a positioning pin 109, and the other end is recessed to form a positioning hole 110 for the positioning pin 109 to be inserted. The positioning pin 109 and the positioning hole 110 are correspondingly set in shape and number. The number can be, but is not limited to, one, two or three, etc., and they are distributed on the upper plate 111 and the lower plate 112. The positioning pin 109 is preferably cylindrical, and the end of the positioning pin 109 away from the transmission rack 2 is tapered, which is more conducive to the positioning pin 109 being inserted into the positioning hole 110. During the docking process of two adjacent half-rails 1a, the positioning pin 109 is first aligned with the positioning hole 110. During the insertion process, the insert 101 is inserted into the slot 103, and the latch 102 is engaged with the latching groove 117 to lock the two adjacent half-rails 1a.

[0080] In some examples, both the half-rail 1a and the drive rack 2 are made of insulating material, which can be, but is not limited to, plastic. Plastic is lightweight and inexpensive, and both are injection molded, possessing high strength and rigidity. The half-rail 1a and the drive rack 2 have different cross-sectional shapes along their respective length directions, such as... Figures 20-21 As shown.

[0081] Working principle:

[0082] During assembly, firstly, the flange 302 of the sliding contact line 3 is inserted into the limiting groove 210 of the corresponding transmission rack 2 to complete the assembly. Then, the positioning bosses 202 at both ends of the transmission rack 2 are engaged in the positioning grooves 105 at both ends of the half rail 1a. At the same time, the first locking bar 203 is engaged in the first locking groove 106, the second locking bar 107 is engaged in the second locking groove 204, and the elastic locking hook 201 is engaged in the locking groove 104 under pressure to lock the transmission rack 2 and the half rail 1a on one side. Then, the above operation is repeated to lock the transmission rack 2 and the half rail 1a on the other side. At this time, the transmission rack 2 and the corresponding side rail 1 are assembled to form the track unit 100.

[0083] Then, multiple track units 100 are sequentially spliced ​​to form a curtain track of a predetermined length. During the splicing process, the positioning pins 109 and positioning holes 110 of two adjacent half-tracks 1a are aligned and inserted. At the same time, the insert 101 on one half-track 1a is inserted into the slot 103 in the other half-track 1a. The latch 102 on the insert 101 engages with the snap-fit ​​groove 117 to lock the two adjacent half-tracks 1a. Meanwhile, the transmission racks 2 in the two adjacent side tracks 1 are positioned and assembled by the insertion of the positioning protrusion 205 and the groove 206.

[0084] 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.
