Description

Technical Field

[0001] This utility model relates to the field of electric curtain technology, and in particular to a splicing intelligent curtain power supply track. Background Technology

[0002] Currently, existing curtain track systems typically employ an on-site measurement and custom cutting installation method. First, the actual dimensions of the window or installation location must be measured at the installation site. Then, based on the measurement results, a track material slightly longer than the actual requirement is selected and cut on-site or in a warehouse to fit the specific size requirements.

[0003] However, manual measurement is susceptible to environmental, tool, and operator experience factors, often resulting in dimensional deviations. This leads to the track not meeting installation requirements after the initial cutting, necessitating secondary or even multiple corrective cuttings. Such repetitive operations not only waste materials but also require multiple trips between the installation site and the warehouse or processing point, significantly reducing installation efficiency. Furthermore, existing tracks often employ a one-piece long rod structure, which, even after cutting, is typically still quite long, placing high demands on transportation vehicles, handling routes, and storage space, increasing logistical difficulties and costs.

[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 1-18 As shown, a modular smart curtain power supply track includes: The track unit 100 has a plurality of units arranged sequentially along its length. Each track unit 100 includes a transmission rack 1, a side rail assembly 2 having a mounting cavity for mounting the transmission rack 1, and a side locking mechanism for locking the side rail assembly 2 to the transmission rack 1. The lengths of each track unit 100 may be equal or unequal. The transmission rack 1 has a plurality of spaced teeth along its length. The docking unit, located between two adjacent track units 100, includes a side rail docking mechanism for locking two adjacent side rail assemblies 2 and a rack docking mechanism for locking two adjacent transmission racks 1; there are also several docking units, and several docking units can sequentially splice several track units 100 to form a curtain track of any length. The power supply unit 3 includes a power supply housing 301 and a sliding contact line 302 electrically connected to the power supply housing 301. The sliding contact line 302 is inserted inside the transmission rack 1 along its length and abuts against the side locking mechanism to prevent it from loosening. The power supply housing 301 has an insertion hole 303 for inserting the track unit 100 located at the first end. The track unit 100 and the power supply housing 301 are provided with a lateral locking mechanism for locking the two laterally and a longitudinal locking mechanism for locking the two longitudinally. The power supply unit 301 can supply power to the sliding contact line 302 to open or close the curtain through the traction unit. Each transmission rack 1 has at least two sliding contact lines 302, which can be powered by DC or AC. When the track unit 100 is spliced, the sliding contact lines 302 inside it are also connected in sequence. Tail frame unit 4 is movably mounted on track unit 100 located at the tail end, and the two are plugged into each other. Tail frame unit 4 has a socket for track unit 100 to be inserted. During installation, the side rail assembly 2 and the transmission rack 1 are first locked together using the side locking mechanism to form a track unit 100. Then, the sliding contact line 302, which corresponds to the length of the track unit 100, is inserted into the transmission rack 1 to form an electric track unit. Several electric track units are then assembled sequentially through the docking unit to form a curtain track of a predetermined length. Finally, the track unit 100 at the first end is inserted into the socket 303 of the power supply unit 301, and the power supply unit 301 and the track unit 100 inserted therein are separated by the horizontal locking mechanism and the vertical locking mechanism. The track unit 100 at the last end is then connected to the tail frame unit 4, and the track length is finely adjusted by adjusting the position of the tail frame unit 4. This invention utilizes a side-locking mechanism to lock the side rail assembly 2 and the transmission rack 1 to form a track unit 100. The side rail assembly unit is then sequentially spliced ​​using a side rail docking mechanism and a rack docking mechanism. The length of the curtain track is finely adjusted using the tail frame unit 4 to form a curtain track of a predetermined length. Finally, the power supply unit 3 is locked to the track unit 100 using a horizontal locking mechanism and a vertical locking mechanism to supply power to the track and form a power supply track. This eliminates the need for multiple corrections and cuts, improving installation efficiency and reducing logistics costs.

[0020] In some examples, the first track unit 100 located at the head of the plurality of track units 100 is the head track unit 100a. The lateral locking mechanism includes a side wing 101 protruding from the transmission rack 1 in the width direction of the head track unit 100a and a wing groove 304 recessed from the insertion hole 303 for the side wing 101 to be engaged to restrict its lateral disengagement. The number of side wings 101 can be one, two, or three, etc. In this embodiment, there are two side wings 101 and they are symmetrically distributed to form a pair. There are also two wing grooves 304. The two side wings 101 correspond one-to-one with the two wing grooves 304, and each side wing 101 is engaged in its corresponding wing groove 304.

[0021] In some examples, the longitudinal locking mechanism includes a hook 102 disposed on the first end track unit 100a and a fixed seat 305 protruding from the insertion hole 303 and for the hook 102 to pass over and hook to restrict its longitudinal disengagement. The hook 102 is located on the transmission rack 1 and has a guide ramp and a locking plane. The guide ramp facilitates the hook 102 passing over the fixed seat 305, and the locking plane is used to abut against the fixed seat 305 to lock the fixed seat 305.

[0022] In some examples, the transmission rack 1 has a conductive cavity 103 inside for mounting and confining the sliding contact line 302. Each sliding contact line 302 has a stationary contact 306 at both ends and a movable contact 307 that is elastically set and used for conductive contact with the stationary contact 306. The stationary contact 306 is embedded in the mounting hole formed on the end face of the sliding contact line 302 and does not protrude from the end face of the sliding contact line 302. The movable contact 307 is elastically mounted in the mounting hole of the sliding contact line 302 and protrudes from the end face of the sliding contact line 302. When the track unit 100 is docked, the movable contact 307 of two adjacent sliding contact lines 302 makes elastic contact with the stationary contact 306 to transmit current. Specifically, the sliding contact line 302 includes a column 3021 with a slot and an extension 3022 extending from the slot to both sides. The conductive cavity 103 has a protrusion 118 extending into the slot to define the circumference of the column 3021 and a plurality of pressure blocks 119 spaced along the length of the column 3021 and used to abut against the extension 3022. The transmission rack 1, the protrusion 118 and the pressure blocks 119 surround to form the conductive cavity 103. The pressure blocks 119 in the same conductive cavity 103 are divided into two groups. A notch is left between the two opposing pressure blocks 119 for the column 3021 to extend out. The column 3021 extends out of the notch and makes conductive contact with the conductive part of the traction unit. A stationary spring 308 is installed inside the power supply main unit 301. An elastic spring 309 is installed inside the transmission rack 1 in the first end track unit 100a to electrically connect the stationary spring 308 and the sliding contact line 302. The stationary spring 308 is installed on the wall of the socket 303. The elastic spring 309 is elastically installed inside the transmission rack 1, with one end electrically connected to the sliding contact line 302 and the other end extending out of the transmission rack 1 and electrically connected to the stationary spring 308. This achieves sequential conduction of the stationary spring 308, the elastic spring 309, and the sliding contact line 302. The elastic spring 309 serves as a bridge between the power supply input terminal and the sliding contact line 302 to conduct current, and can input DC or AC power.

[0023] In some examples, the transmission rack 1 in the first end track unit 100a protrudes to form an end boss 104 for limiting the sliding contact line 302. When the sliding contact line 302 abuts against the end boss 104, the sliding contact line 302 is installed in place. Furthermore, the end boss 104 provides a mounting recess 105 for the elastic spring 309 to overlap, and a positioning recess 105 is formed thereon for positioning the elastic spring 309. The positioning recess 105 can limit the elastic spring 309 from shifting along the width direction of the track unit 100. The end of the elastic spring 309 near the sliding contact line 302 is embedded in the positioning recess 105 and extends in the direction of the sliding contact line 302. The extended part is bent from the end boss 104 to form a bent part. The bent part is attached to the side of the end boss 104 (i.e., the contact surface between the end boss 104 and the sliding contact line 302) and makes conductive contact with the sliding contact line 302. The elastic spring 309 and the sliding contact line 302 are locked together by the connecting screw 120 to form a conductive whole, forming a conductive path. The end of the transmission rack 1 has a guide hole 117 for the connecting screw 120 to enter. The connecting screw 120 can be accurately positioned by entering through the guide hole 117.

[0024] In some examples, the drive rack 1 in the first end track unit 100a has a mounting groove 106 for the locking hook 102 to be rotatably mounted, and the mounting groove 106 is provided with an elastic element 107 for pressing the locking hook 102 against the fixed seat 305 to longitudinally lock the first end track unit 100a and the power supply main unit 301. The elastic element 107 can be a compression spring. The drive rack 1 has an inlet hole 123 that communicates with the mounting groove 106 and allows the elastic element 107 to enter, and a compression spring mounting hole for mounting the elastic element 107. First, the spring element enters the compression spring mounting hole from the inlet hole 123 and the mounting groove 106, and then the compression spring is pressed to make room for the locking hook 102 to enter.

[0025] The locking hook 102 includes a rotating arm 1021 and a hook portion 1022. The insertion hole 303 protrudes to form an overlapping platform 121 for the end of the rotating arm 1021 to overlap and a blocking buckle 122 that limits the rotating arm 1021 on the overlapping platform 121. The overlapping platform 121 has an arc-shaped bayonet. Each locking hook 102 corresponds to two overlapping platforms 121 and two blocking buckles 122. An active cavity for the rotating arm 1021 to move is formed between each overlapping platform 121 and its corresponding blocking buckle 122. The hook portion 1022 protrudes to form an abutment portion for abutting against the elastic element 107. The two ends of the rotating arm 1021 along its axial direction are chamfered to facilitate entry into the active cavity and prevent slippage. The transmission rack 1 has a roller mounting hole 124 for inserting the movable roller 5, and the movable roller 5 enters or exits the track through the roller mounting hole 124.

[0026] In some examples, the track unit 100 located at the tail end of the plurality of track units 100 is the tail end track unit 100b. Either the transmission rack 1 or the tailstock unit 4 in the tail end track unit 100b is provided with an elastic buckle 401, and the other is provided with an insertion hole 108 for the elastic buckle 401 to be inserted to define the position of the tailstock unit 4. The elastic buckle 401 and the insertion hole 108 can have a one-to-many or many-to-one relationship. In this embodiment, the elastic buckle 401 is located on the tailstock unit 4 and there is only one elastic buckle 401. The insertion hole 108 is located on the transmission rack 1. The rack 1 has multiple mounting holes 108 arranged sequentially along the length of the rack 1. The tailstock unit 4 has a groove for mounting an elastic buckle 401. The elastic buckle 401 includes a spring piece and a buckle body protruding from the spring piece. One end of the spring piece is connected to the groove wall, and the other end is suspended to form an elastic mechanism. The buckle body matches the shape of the mounting hole 108, and can be, but is not limited to, square, round, etc. The tailstock unit 4 can be fixed at different positions of the track unit 100 by embedding the buckle body into the mounting holes 108 at different positions.

[0027] In some examples, the side rail assembly 2 includes two opposing side rail units 2a, which together form the aforementioned mounting cavity. The side locking mechanism includes side latches 109 located on the transmission rack 1 and the side rail unit 2a, respectively, and side holes 201 for the side latches 109 to engage. There are multiple side latches 109 and side holes 201, which are spaced apart along the length of the track unit 100. They correspond one-to-one, and each side latch 109 engages in its corresponding side hole 201.

[0028] In this embodiment, the side latch 109 is located on the transmission rack 1, and the side hole 201 is located on the side rail unit 2a. When the side latch 109 on the transmission rack 1 is subjected to force and deforms, it can be locked into the side hole 201 on the side rail unit 2a. Then, the side latch 109 resets and hooks the side rail unit 2a to prevent the two from separating. However, when the side rail is under excessive load or force, the side latch 109 may undergo elastic deformation and separate from the transmission rack 1. After the sliding contact line 302 is inserted into the conductive cavity 103 of the transmission rack 1, it is located in the direction of deformation of the side latch 109. The side latch 109 has no space to deform, thereby preventing the side latch 109 from deforming and firmly locking the side rail unit 2a.

[0029] Preferably, the side-mounted locking mechanism further includes: The rack side 115 extends to both sides from the transmission rack 1 along its width direction; The track side groove 208 is formed on one side of the two side rail units 2a that are close to each other so that the rack side 115 can be inserted into it; The track side 209 extends from the side track unit 2a toward the transmission rack 1; And a rack side groove 116, which is located on the transmission rack 1 and has an opening facing the side of the track 209 for it to be engaged.

[0030] As the rack side 115 engages with the track side groove 208, the track side 209 also engages with the rack side groove 116 to form a cross lock. Furthermore, the rack side 115, track side groove 208, track side 209, and rack side groove 116 all extend along the length of the track unit 100, ensuring that the transmission rack 1 and the side rail unit 2a are engaged throughout their entire length, thereby improving the connection strength between the two.

[0031] Preferably, the side-connection locking mechanism further includes a side-connection boss 110 located at the end of the transmission rack 1 and the end of the side rail unit 2a, and a side-connection groove 202 for the side-connection boss 110 to be engaged. When the transmission rack 1 and the side rail unit 2a are assembled, the side-connection boss 110 and the side-connection groove 202 are first aligned and inserted. During the process, the elastic side-connection latch 109 is engaged in the side-connection hole 201 to lock the transmission rack 1 and the side rail unit 2a.

[0032] In some examples, the transmission rack 1 in the first track unit 100a protrudes to form a docking part 111 for docking with its corresponding side rail assembly 2. After docking, the outer surfaces of the two are flush. The docking part 111 and the side rail respectively have protruding docking posts 203 and recessed docking holes 112 for the docking posts 203 to be inserted into. The side wing 101 is located on the docking part 111. The number of docking posts 203 and docking holes 112 are corresponding, and each docking post 203 is inserted into its corresponding docking hole 112 to accurately position the transmission rack 1 and the side rail assembly 2. The shape of the docking posts 203 and docking holes 112 can be, but is not limited to, rectangular or circular shapes.

[0033] In some examples, the side rail docking mechanism includes a connecting piece 204 protruding from one end of the side rail unit 2a, a connecting groove 205 recessed at the other end of the side rail unit 2a for the connecting piece 204 to be engaged, a connecting buckle 206 elastically disposed on the connecting piece 204, and a fastening groove 207 recessed in the connecting groove 205 for the connecting buckle 206 to be engaged. Each side rail unit 2a includes an upper part, a lower part, and a side part for connecting the upper part and the lower part to form a "U"-shaped structure. The upper part protrudes downward to form an upper stop bar, and the lower part protrudes upward to form a lower stop bar. The upper stop bar, the lower stop bar, and the side part together form the connecting groove 205. The side part forms the bottom of the connecting groove 205, and the fastening groove 207 is formed by the recess at the bottom of the connecting groove 205. The connecting buckle 206 is elastically mounted on the connecting piece 204. The specific structure can be: the connecting... The connecting piece 204 has a groove, one end of the connecting buckle 206 is fixed to the groove wall, and the other end is suspended. The connecting buckle 206 protrudes towards the fastening groove 207 to form a protrusion for embedding into the fastening groove 207. The side rail unit 2a has a separation hole 210 corresponding to the fastening groove 207, which communicates with the fastening groove 207. When the curtain track is disassembled, a tool can be inserted into the fastening groove 207 through the separation hole 210 to push the connecting buckle 206 out of the fastening groove 207 so that the two are unlocked. At this time, the connecting piece 204 can be withdrawn from the connecting hole.

[0034] Preferably, the side rail docking mechanism further includes a side rail docking protrusion 211 formed by the protrusion of one end of the side rail unit 2a and a side rail docking recess 212 formed by the recess of the other end of the side rail unit 2a for the side rail docking protrusion 211 to be inserted into. The side rail docking protrusion 211 and the side rail docking recess 212 are matched in shape and correspond in number. The number can be, but is not limited to, one or two.

[0035] The rack and pinion docking mechanism includes a rack and pinion docking protrusion 113 formed by protruding from one end of the transmission rack 1 and a rack and pinion docking recess 114 formed by recessing from the other end of the transmission rack 1 for the rack and pinion docking protrusion 113 to be engaged. The rack and pinion docking protrusion 113 and the rack and pinion docking recess 114 are matched in shape and correspond in number. The number can be, but is not limited to, one or two.

[0036] Working principle: During assembly, firstly, the side connecting boss 110 and the side connecting groove 202 are aligned and inserted. During this process, the rack side 115 is inserted into the track side groove 208, and the track side 209 is also inserted into the rack side groove 116. The side connecting buckle 109 is inserted into the side connecting hole 201 to lock the transmission rack 1 and the side rail unit 2a located on one side. Then, the sliding contact line 302 is inserted into the conductive cavity 103. The protrusion 118 in the guide cavity limits the circumferential movement of the sliding contact line 302. At the same time, the sliding contact line 302 located in the direction of deformation of the side connecting buckle 109 occupies the deformation space of the side connecting buckle 109, so that the side connecting buckle 109 can be firmly locked by the side rail unit 2a. Repeat the above steps to lock the transmission rack 1 and the side rail unit 2a located on the other side. At this time, the transmission rack 1, the side rail assembly 2 with its corresponding length, and the sliding contact line 302 are assembled to form the track unit 100.
