Description

Technical Field

[0001] This utility model relates to the field of low-voltage rail-mounted power supply technology, and in particular to a low-voltage rail-mounted power supply system and its modular structure. Background Technology

[0002] Low-voltage rail-mounted power supply systems use a safe voltage of 36V or lower, significantly reducing the risk of electric shock. Furthermore, due to their sliding accessories such as rail sockets, they allow for easy adjustment of the number of rail sockets to support multiple devices simultaneously, providing greater flexibility and safety for electrical loads. This eliminates the need for rewiring and reduces expansion costs, thus offering broad application prospects. However, practical applications still have some inconveniences. For example, rail sockets need to be connected from both ends of the rail, and electrical loads such as lighting fixtures can only slide in one direction, preventing multi-directional adjustment of the lighting angle and making it difficult to adapt to changing electrical environments. The rotary sliding power-collecting device disclosed in patent document CN217903633U includes a conductive slide rail connected to a power source, a conductive component that moves along the conductive slide rail, a housing that rotates around the conductive component, and a power-collecting needle disposed on the housing; the power-collecting needle contacts the conductive component; the power-collecting needle connects to the electrical load; it solves the problem that the prior art can only meet the lighting needs of a single direction and cannot meet the lighting needs of various directions; however, when it is necessary to add or remove the electrical load, the conductive slide rail needs to be disassembled and assembled first, and the conductive component needs to be inserted or removed from both ends of the conductive slide rail before it can be realized, so there is still a problem of inconvenient installation. Utility Model Content

[0003] To address the problems in related technologies, this application discloses a low-voltage rail-mounted power supply system and its modular structure. By adopting a set of semi-circular ring structures, the power load can be increased or decreased without modifying the existing power circuit, and the installation angle of the power load can be flexibly adjusted in multiple directions.

[0004] To achieve the above objectives, this application provides the following technical solution: a low-voltage rail-mounted power supply system and its modular structure, including a power supply rail, an internal power collection ring that is slidably fitted on the power supply rail, and a power collection base that is rotatable and fitted outside the internal power collection ring. The internal power collection ring is a pair of semi-circular components. The power supply rail is electrically connected to the internal power collection ring, and the internal power collection ring is electrically connected to the power collection base.

[0005] By adopting the above technical solution, the electrical load installed on the power collection base is electrically connected through the power collection base, the internal power collection ring, and the power supply rail. When a new electrical load needs to be added, a pair of semi-circular components can be directly fitted onto the power supply rail, and then the power collection base can be fitted onto the internal power collection ring. There is no need to fit it from both ends of the power supply rail, which makes it convenient and quick to add or remove electrical loads. The internal power collection ring can slide up and down along the power supply rail. The shape of the internal power collection ring is a complete circle, which makes it convenient for the power collection base to rotate 360° around the internal power collection ring and the power supply rail. The installation angle of the electrical load can be quickly adjusted by adjusting the position of the internal power collection ring and the power collection base.

[0006] As a further aspect of this application: the power supply track is an electrically insulated cylindrical track rod, with a pair of conductive slide rails symmetrically arranged along the axis of the power supply track. Each conductive slide rail contains a metal conductive strip, and the conductive slide rail is a concave groove. The metal conductive strip is located at the bottom of the groove, and the internal power-taking ring is slidably electrically connected to the metal conductive strip. The cylindrical track rod facilitates the rotation of the power-taking base around the internal power-taking ring and the power supply track. The symmetrical arrangement along the axis and the concave structure facilitate the stable engagement of the internal power-taking ring on the power supply track and its sliding along the track. Furthermore, this structure ensures a stable electrical connection between the internal power-taking ring and the power supply track.

[0007] As a further aspect of this application: the semi-circular component is equipped with telescopic gold fingers, and the outer surface of the semi-circular component is provided with two parallel and electrically insulated metal conductive rings. One end of the telescopic gold finger is electrically connected to one of the metal conductive rings, and the other end of the telescopic gold finger is slidably electrically connected to the power supply rail. The semi-circular component is also equipped with an error-proof structure. The identical semi-circular component structure design simplifies the manufacturing process. When the inner conductive ring is fitted onto the conductive slide rail, the telescopic gold finger is embedded in the concave groove of the conductive slide rail, and the top of the telescopic gold finger elastically presses against the metal conductive strip at the bottom of the groove and can slide with the groove. An error-proof structure is provided at the mating end of the semi-circular component. The error-proof structure includes a conventional concave-convex structure set on the mating surface. This type of error-proof structure is simple in design and easy to implement. When assembling the two semi-circular components into the inner power-taking ring of a complete ring, one of the semi-circular components must be rotated 180° relative to each other. This ensures that the two telescopic gold fingers on the inner conductive ring are electrically connected to the two parallel and electrically insulated metal conductive rings on the outer surface of the inner power-taking ring, thereby avoiding the safety problem of short circuit due to assembly errors.

[0008] As a further aspect of this application: the error-proof structure includes a pair of magnets with opposite polarities embedded in the mating surface of the semi-circular component. This structure not only ensures correct assembly by utilizing the properties of like poles repelling and unlike poles attracting, but also allows the magnets to directly attract and fit onto the power supply track. A metal conductive ring extends to the mating surface of the semi-circular component. This structure helps to fix the metal conductive ring on the semi-circular component and improves the metal conductivity of the mating surface of the internal conductive ring, preventing poor electrical connection of the telescopic gold fingers when switching between the two semi-circular components.

[0009] As a further aspect of this application: the power-collecting base includes a power-collecting end and a fixed end, which are fitted and fixed on the power supply rail and the internal power-collecting ring by a detachable connection structure. The power-collecting end is provided with a power-collecting needle, one end of which is slidably electrically connected to the metal conductive ring of the internal power-collecting ring, and the other end of which is electrically connected to the electrical load. The fixed end is provided with a locking device, which can fix the power-collecting base on the power supply rail. This structure uses a detachable connection device to fit the power-taking base onto the internal power-taking ring, allowing for the addition or reduction of electrical loads without disassembling the existing power supply circuit. When an electrical load (such as a light) is installed at the power-taking end, the installation angle of the load can be adjusted by rotating the power-taking base around the internal power-taking ring and the power supply track. By setting a power-taking pin at the power-taking end and elastically connecting the pin to the metal conductive ring of the internal power-taking ring, the load installation position can be adjusted by rotating around the metal conductive ring and sliding the electrical connection. This structure separates the power-taking circuit and the fixed structure, facilitating functional adjustments as needed during actual use.

[0010] As a further aspect of this application, detachable connection structures are respectively disposed on both sides of the power-gathering end and the fixed end. The detachable connection structures include a snap-on structure and a hinge structure. When one side of the detachable connection structure of the power-gathering base is a hinge structure and the other side is a snap-on structure, it not only facilitates installation and disassembly, but also ensures that the power-gathering base is always in a complete structural state and will not cause the problem of accidental loss of parts.

[0011] As a further aspect of this application: the power-collecting end includes a track-mounted power-collecting plate fixed on the power-collecting end and a rotating part that can rotate around the axis of the power-collecting end. The power-collecting needle is electrically connected to the track-mounted power-collecting plate, and the track-mounted power-collecting plate is rotatably electrically connected to the rotating part. When the electrical load is installed on the rotating part, the installation angle of the electrical load can be adjusted by rotating the electrical load around the axis of the power-collecting end.

[0012] As a further aspect of this application: the track-mounted power-collecting plate is provided with a conductive ring located at the axis and a coaxial annular conductive ring, and the power-collecting needles are fixedly electrically connected to the conductive ring and the annular conductive ring respectively; the rotating part is provided with two rotating power-collecting posts, which are rotatably electrically connected to the conductive ring and the annular conductive ring respectively. In this structure, when the rotating part rotates around the axis of the power-collecting end, the two rotating power-collecting posts of the rotating part are elastically connected to the conductive ring and the annular conductive ring on the track-mounted power-collecting plate and rotate around the axis of the power-collecting end, which helps to maintain a stable electrical connection during rotation.

[0013] As a further aspect of this application: the locking device includes a locking switch and a locking structure. The locking structure allows the power-taking base to be fixedly fitted onto the power supply rail, and the locking switch allows the locking structure to switch between a fixed state and a released state. The locking switch includes a pull ring and a cam, and the locking structure includes an elastic pressing plate and a damping block disposed on the elastic pressing plate and extending out of the fixed end. The damping block presses against the power supply rail, and the elastic pressing plate is elastically connected to the fixed end via a spring. When the pull ring is pulled, this structure causes the cam to move towards the pull ring, and the elastic pressing plate springs up towards the pull ring. The damping block disposed on the elastic pressing plate also moves towards the pull ring, thereby releasing the power-taking base from the power supply rail, at which point it can slide or rotate axially along the power supply rail. When the pull ring is released, the cam moves towards the power supply rail, pushing the elastic pressing plate towards the power supply rail, and the damping block presses against the power supply rail, thus fixing the power-taking base onto the power supply rail.

[0014] As a further aspect of this application, a rail-mounted quick-connect interface is also included. This interface comprises a fixing device, a pair of elastic conductive posts, and an electrical connection terminal. Both the rail and fixing devices are detachable. The fixing device secures the quick-connect interface to the power supply rail. The elastic conductive posts are slidably electrically connected to the power supply rail, and are electrically connected to the electrical connection terminal. The electrical connection terminal is electrically connected to an external low-voltage constant-current power supply or electrical load. This structure, through the elastic conductive posts and the detachable fixing device, allows the quick-connect interface to be fixed to the power supply rail and slide along it, achieving a stable electrical connection between the external low-voltage constant-current power supply or electrical load and the power supply rail.

[0015] In summary, the beneficial effects of this application are as follows: 1. The design of the internal power-taking ring allows the electrical load to slide along the power supply track to adjust the installation position; the power-taking base is fitted outside the internal power-taking ring, allowing the electrical load to rotate around the power supply track to adjust the installation angle; the rotating part allows the electrical load to rotate around the power-taking base to adjust the installation angle, ultimately enabling the electrical load to freely adjust its installation angle in three directions: along the power supply track, in a plane perpendicular to the power supply track, and in a plane parallel to the power supply track.

[0016] 2. The two semi-circular ring components fit together to form the internal power-taking ring. The power-taking base adopts a detachable fixing and rotating design, which can easily add or reduce the electrical load and flexibly adjust the installation angle of the electrical load without modifying the existing electrical circuit.

[0017] 3. The adoption of a fault-proof structure not only simplifies the internal power-taking ring structure but also avoids the risk of circuit misconnection, thus improving electrical safety.

[0018] 4. It adopts a modular design including internal power take-up ring, power take-up base, power supply rail, and rail power supply quick interface. Each module is designed to be detachable, and the entire low-voltage rail power supply system can be installed without the use of special tools. It can be flexibly assembled into various power circuits for various power use environments.

[0019] 5. The rail-mounted power supply quick interface is adopted to flexibly realize the circuit connection between the various components of the entire low-voltage rail-mounted power supply system and its modular structure. Attached Figure Description

[0023] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects disclosed in this embodiment as detailed in the appended claims.

[0024] It should be noted that all directional indicators in the embodiments (such as up, down, left, right, front, back, etc.) are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0025] Furthermore, the use of terms such as "first" and "second" in the embodiments is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit this application. It is merely to distinguish components or operations described using the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0026] To further understand the content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings: Example 1 like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, a low-voltage rail-mounted power supply system and its modular structure include a power supply rail 2, an internal power collection ring 4 that is slidably fitted on the power supply rail, and a power collection base 3 that is rotatable and fitted outside the internal power collection ring 4. The internal power collection ring 4 is a pair of semi-circular components 404. The power supply rail 2 is electrically connected to the internal power collection ring 4, and the internal power collection ring 4 is electrically connected to the power collection base 3.

[0027] like Figure 12 As shown, the rail power supply quick interface 1 includes a fixing device 101, a pair of elastic conductive posts 102, and an electrical connection end 103. The fixing device 101 is detachable and fixes the rail power supply quick interface 1 to the power supply rail 2. The elastic conductive posts 102 are slidably electrically connected to the power supply rail 2 and electrically connected to the electrical connection end 103. The electrical connection end 103 is electrically connected to an external power source or electrical load. The rail power supply quick interface 1 adopts a silicone coating process, which has good insulation performance, is soft, and has a certain degree of plasticity.

[0028] like Figure 2 , Figure 5 As shown, the power supply track 2 is an electrically insulated track rod 201. A pair of conductive slide rails 202 are symmetrically arranged along the axis of the track rod 201. The conductive slide rail 202 is provided with a metal conductive strip 203. The conductive slide rail 202 is a concave groove 204. The metal conductive strip 203 is set at the bottom of the groove 204. The concave groove 204 is made of elastic insulating material such as rubber, and its open end is in an elastic closed state, which can prevent dust and avoid accidental contact of the metal conductive strip 203 by the human body.

[0029] like Figure 4 , Figure 5 As shown, the semi-circular component 404 is provided with telescopic gold fingers 401. Two parallel and electrically insulated metal conductive rings 402 are provided on the outer surface of the semi-circular component 404. One end of the telescopic gold finger 401 is electrically connected to one of the metal conductive rings 402, and the other end of the telescopic gold finger 401 extends into the bottom of the groove 204 of the power supply track 2, and is slidably electrically connected to the metal conductive strip 203. When the inner conductive ring 2 slides along the power supply track 2, the telescopic gold finger 401 slides within the groove 204 while maintaining a slidably electrically connected connection with the metal conductive strip 203. An anti-misalignment structure 403 is provided at the mating end of the semi-circular component 404. The anti-misalignment structure 403 includes a conventional concave-convex structure on the mating surface, ensuring that when assembling the two semi-circular components 404 into a complete inner power-taking ring 4, one of the semi-circular components 404 must be rotated 180° relative to the other. This ensures that the two telescopic gold fingers 401 on the inner conductive ring 4 are respectively electrically connected to the two parallel and electrically insulated metal conductive rings 402 on the outer surface of the inner power-taking ring 4.

[0030] like Figure 5As shown, the error-proof structure 403 also includes a pair of magnets 405 with opposite magnetic properties embedded in the mating end of the semi-circular component 404. That is, one magnet embedded in the mating end of the semi-circular component 404 is an S pole and the other is an N pole. The mutual attraction of the N and S poles allows the semi-circular component 404 to automatically fit onto the power supply track 2. The metal conductive ring 402 extends to the mating surface of the semi-circular component 404. This structure is beneficial for fixing the metal conductive ring 402 on the semi-circular component 404 during installation and for stabilizing the electrical connection when the telescopic gold finger 401 switches on the outer surface of the two semi-circular components 404.

[0031] like Figure 3 , Figure 6 , Figure 7 , Figure 11 As shown, the power-collecting base 3 includes a power-collecting end 9 and a fixed end 10. The power-collecting end 9 and the fixed end 10 are fitted and fixed on the power supply rail 2 and the internal power-collecting ring 4 through a detachable connection structure 5. The power-collecting end 9 is provided with a pair of power-collecting needles 301. When the power-collecting base rotates around the internal power-collecting ring 4, the power-collecting needles 301 slide and are electrically connected on the two metal conductive rings 402 of the internal power-collecting ring 4 respectively. The other end of the power-collecting needles 301 is electrically connected to the electrical load. The fixed end 10 is provided with a locking device 6, which can fix the power-collecting base 3 on the power supply rail 2.

[0032] like Figure 3 , Figure 11 As shown, detachable connection structures 5 are provided on both sides of the power-taking end 9 and the fixed end 10. One of the detachable connection structures 5 is a buckle structure 501, and the other is a hinge structure 502.

[0033] like Figure 7 , Figure 8 As shown, the power-collecting end 9 includes a track power-collecting plate 7 fixed on the power-collecting end 9 and a rotating part 8 that can rotate around the axis of the power-collecting end 9. The power-collecting needle 301 is electrically connected to the track power-collecting plate 7, and the track power-collecting plate 7 is rotatably electrically connected to the rotating part 8. The power-collecting end 9 is also provided with a rotating connection structure, which includes a rotating positioning structure 902 disposed on the track power-collecting plate 7 and a rotating structure 901 disposed on the rotating part 8. When the rotating part 8 rotates around the axis of the power-collecting base 3, the rotating structure 901 rotates and presses the rotating positioning structure 902 to a horizontal position. When the rotating structure 901 stops rotating, the elastic steel ball of the rotating positioning structure 902 pops out and can be locked in the semi-circular hole on the rotating structure 901.

[0034] The track power-collecting plate 7 is provided with a conductive ring 701 located at the axis and a coaxial annular conductive ring 702. The power-collecting needle 301 is fixedly electrically connected to the conductive ring 701 and the annular conductive ring 702 respectively. The rotating part 8 is provided with two rotating power-collecting columns 801, which are rotatably electrically connected to the conductive ring 701 and the annular conductive ring 702 respectively.

[0035] like Figure 10 , Figure 11 As shown, the fixed end 10 is equipped with a locking device 6, including a locking switch 601 and a locking structure 602. The locking structure 602 allows the power-taking base 3 to be fixedly fitted onto the power supply rail 2. The locking switch 601 allows the locking structure 602 to switch between a fixed state and a released state. The locking switch 601 includes a pull ring and a cam. The locking structure 602 includes an elastic pressing plate 603 and a damping block 604 disposed on the elastic pressing plate 603. When the pull ring is pulled up, the cam is pulled up along with the pull ring. The elastic pressing plate 603 moves upward under the action of the spring, causing the damping block 604 to move upward together. The damping block leaves the power supply rail 2, so that the power-taking base 3 is in a released state from the power supply rail 2. When the pull ring is released, the cam is pressed down along with the pull ring, causing the elastic pressing plate 603 to move downward, causing the damping block 604 to move downward together. The damping block 604 presses against the power supply rail 2, so that the power-taking base 3 is in a fixed state from the power supply rail 2.

[0036] like Figure 12 , Figure 13 As shown, the rail power supply quick interface 1 includes a fixing device 101, a pair of elastic conductive posts 102, and an electrical connection end 103. The fixing device 101 is detachable and fixes the rail power supply quick interface 1 onto the power supply rail 2. The elastic conductive posts 102 are slidably electrically connected to the power supply rail 2, and the elastic conductive posts 102 are electrically connected to the electrical connection end 103. The electrical connection end 103 is electrically connected to an external power source or electrical load.

[0037] like Figure 14 , Figure 15 As shown, the top of the rail power supply quick interface 1 is provided with a fixing device 101 and an electrical connection end 103, and the bottom is provided with a pair of elastic conductive posts 102. The fixing device 101 is detachable and fixes the rail power supply quick interface 1 to the top of the power supply rail 2. The elastic conductive posts 102 are embedded in the slide groove 204 of the power supply rail 2 and are electrically connected to the power supply rail 2. The elastic conductive posts 102 are electrically connected to the electrical connection end 103, and the electrical connection end 103 is electrically connected to an external power source or electrical load.

[0038] like Figure 19The illustration shows a floor-mounted application installation according to this application. The track power supply quick interface 1 includes a detachable fixing device 101, which is detachably fixed to the power supply track 2. A pair of elastic conductive posts 102 are provided on opposite sides of the inner side of the fixing device 101. The track power supply quick interface 1 is fixedly installed on the floor lamp base. When the power supply track 2 is inserted into the fixing device 101, the power supply track 2 can be fixed on the floor lamp base. At this time, the elastic conductive posts 102 extend into the bottom of the slide groove 204 of the power supply track 2 and elastically contact the metal conductive strip 203. The other end of the elastic conductive posts 102 is connected to the external power supply circuit on the floor lamp base.

[0039] When it is necessary to increase the power load and adjust the installation angle, such as to add a wireless camera, the internal power ring 4 and the power base 3 can be fitted onto the appropriate position on the power supply rail 2 to complete the process.

[0040] When an additional electrical load is required and there are no requirements for the installation angle, the previous rail power supply quick interface 1 can be directly fitted and fixed at a suitable position on the power supply rail 2.

[0041] Example 2 like Figure 1 , Figure 2 , Figure 3 As shown, a low-voltage rail-mounted power supply system and its modular structure include a power supply rail 2, an internal power collection ring 4 that is slidably fitted on the power supply rail, and a power collection base 3 that is rotatable and fitted outside the internal power collection ring 4. The internal power collection ring 4 is a pair of semi-circular components 404. The power supply rail 2 is electrically connected to the internal power collection ring 4, and the internal power collection ring 4 is electrically connected to the power collection base 3.

[0042] like Figure 5 As shown, the power supply track 2 is an electrically insulated track rod 201. A pair of conductive slide rails 202 are symmetrically arranged along the axis of the track rod 201. The conductive slide rails 202 are provided with metal conductive strips 203. The conductive slide rails 202 are concave grooves 204, and the metal conductive strips 203 are located at the bottom of the grooves 204.

[0043] The semi-circular component 404 is equipped with a telescopic gold finger 401. Two parallel and electrically insulated metal conductive rings 402 are provided on the outer surface of the semi-circular component 404. One end of the telescopic gold finger 401 is electrically connected to one of the metal conductive rings 402, and the other end of the telescopic gold finger 401 extends into the bottom of the groove 204 of the power supply track 2, where it is slidably electrically connected to the metal conductive strip 203. When the inner conductive ring 2 slides along the power supply track 2, the telescopic gold finger 401 slides within the groove 204 while maintaining a slidably electrically connected relationship with the metal conductive strip 203. A fault-prevention structure 403 is provided at the mating end of the semi-circular component 404.

[0044] like Figure 12As shown, the rail power supply quick interface 1 includes a fixing device 101, a pair of elastic conductive posts 102, and an electrical connection end 103. The fixing device 101 is detachable and fixes the rail power supply quick interface 1 to the power supply rail 2. The elastic conductive posts 102 are slidably electrically connected to the power supply rail 2 and electrically connected to the electrical connection end 103. The electrical connection end 103 is electrically connected to an external power source or electrical load. The rail power supply quick interface 1 adopts a silicone coating process, which has good insulation performance, is soft, and has a certain degree of plasticity.

[0045] like Figure 11 As shown, the power-taking base 3 includes a power-taking end 9 and a fixed end 10. The fixed end 10 is provided with a locking device 6, including a locking switch 601 and a locking structure 602.

[0046] like Figure 9 , Figure 11 As shown, the locking switch 601 is a push button. An elastic pressing plate 603 is fixedly connected below the push button. The elastic pressing plate 603 is elastically connected to the housing of the fixed end 10 via a spring. The elastic pressing plate 603 is fixedly connected to a damping block 604, which extends out of the housing of the fixed end 10 and presses against the power supply rail 2. When the button is pressed, the elastic pressing plate 603 moves downward, causing the damping block 604 to tilt upward and leave the power supply rail 2, releasing the power-taking base 3 from the power supply rail 2. At this time, the power-taking base 3 can rotate around or slide along the power supply rail 2 (simultaneously causing the fitted internal power-taking ring 4 to slide as well). When the button is released, the elastic pressing plate 603 returns to its initial state, causing the damping block 604 to fall back to its initial state, pressing against the power supply rail 2, and the power-taking base 3 remains fixed to the power supply rail 2.

[0047] like Figure 7 , Figure 8 As shown, the power-taking end 9 includes a track power-taking plate 7 fixed on the power-taking end 9 and a rotating part 8 that can rotate around the axis of the power-taking end 9.

[0048] like Figure 12 , Figure 13 , Figure 14 As shown, the track power supply quick interface 1 can be fixed to the top or bottom of the power supply track 2 by the fixing device 101. The elastic conductive post 102 is embedded in the slide groove 204 and electrically connected to the metal conductive strip 203. The elastic conductive post 102 is electrically connected to the electrical connection end 103, which is located at the top of the track power supply quick interface 1.

[0049] like Figure 17 , Figure 18As shown, the track power supply quick interface 1 is located inside the wall-mounted box 106. The wall-mounted box 106 also houses an AC / DC converter 104. The wall-mounted box 106 is compatible with the junction box 11, which is a standard 86 recessed box. When the wall-mounted box 106 is inserted into the junction box 11, the AC / DC converter 104 converts the mains power, which is then used as an external power source and connected to the low-voltage track power supply system via the track power supply quick interface 1. A light strip 205 is also embedded in the power supply track 2. The light strip 205 is electrically connected to a metal conductive strip 203 at the top of the power supply track 2, and can be temporarily inserted into an indoor wall socket as a decorative wall lamp.

[0050] By fitting the internal power-taking ring 4 and the power-taking base 3 at appropriate positions on the power supply rail 2, the electrical load can be increased and its installation angle can be flexibly adjusted.

The internal power collection ring 4 is a pair of semi-circular components 404. The power supply rail 2 is electrically connected to the internal power collection ring 4, and the internal power collection ring 4 is electrically connected to the power collection base 3.

[0052] The power-taking base 3, the internal power-taking ring 4, and the track power supply rapid structure 1 are as described in Example 1, and will not be described in detail in this example.

[0053] like Figure 16 As shown, the power supply rail 2 is suspended from the ceiling. The rail power supply quick interface 1 is detachably fitted onto the power supply rail 2 via the fixing device 101 and then connected to an external power source. The electrical load is fixed to the power supply rail 2 via the power collection base 3 and the internal power collection ring 4. When the position needs to be adjusted, multi-directional adjustments can be made directly by adjusting the position and angle of the rotating part 8, the power collection base 3, and the internal power collection ring 4.

[0054] When it is necessary to increase the power load and adjust the installation angle, such as to add a wireless camera, the internal power ring 4 and the power base 3 can be fitted onto the appropriate position on the power supply rail 2 to complete the process.

[0055] When only an electrical load needs to be added and there are no requirements for the installation angle, such as adding a wireless speaker, the track power supply quick interface 1 can be installed directly at a suitable position on the power supply track 2.

[0056] Example 4 like Figure 1 , Figure 2 , Figure 3The low-voltage rail-mounted power supply system and its modular structure include a power supply rail 2, an internal power collection ring 4 that is slidably fitted on the power supply rail, and a power collection base 3 that is rotatably fitted on the outside of the internal power collection ring 4. The internal power collection ring 4 is a pair of semi-circular components 404. The power supply rail 2 is electrically connected to the internal power collection ring 4, and the internal power collection ring 4 is electrically connected to the power collection base 3.

[0057] like Figure 20 and Figure 21 As shown, the rail power supply quick interface 1 is located at the bottom, and a constant current low voltage power supply 105 is also provided at the bottom. The rail power supply quick interface 1 is connected to the constant current low voltage power supply 105 through the electrical connection terminal 103. The rail power supply quick interface 1 is fixed to the power supply rail 2 by the fixing device 101. The elastic conductive post 102 is embedded in the slide groove 204 of the power supply rail 2 and is electrically connected to the metal conductive strip 203.

[0058] The power-taking base 3, the internal power-taking ring 4, and the track power supply rapid structure 1 are as described in Example 1.

[0059] When it is necessary to increase the power load and adjust the installation angle, such as to add a wireless camera, the internal power ring 4 and the power base 3 can be fitted onto the appropriate position on the power supply rail 2 to complete the process.

[0060] When only an electrical load needs to be added and there are no requirements for the installation angle, such as adding a wireless speaker, the track power supply quick interface 1 can be installed directly at a suitable position on the power supply track 2.

[0061] The implementation principle of a low-voltage rail-mounted power supply system and its modular structure in this application is as follows: 1. A semi-circular component is used to achieve a sliding electrical connection along the power supply track, enabling quick assembly and disassembly and allowing adjustment of the electrical load position along the power supply track; and a fault-proof structure is adopted to avoid the risk of short circuit due to incorrect connection; 2. By adopting a method of rotating the power-taking base around the semi-circular component and the power supply rail while maintaining the rotating electrical connection, the position of the electrical load can be adjusted 360° on a plane perpendicular to the power supply rail without disassembly; 3. By adopting a rotating part that rotates around the power-taking base and maintains the rotating electrical connection, the position of the electrical load can be adjusted 360° on a plane parallel to the power supply track without disassembly; 4. By using the structure of the internal power-taking ring fitting into the power supply rail and the power-taking base fitting into the internal power-taking ring, the position of the electrical load in the XYZ coordinate directions based on the power supply rail can be adjusted without disassembly. 5. The system adopts a modular design, breaking down the entire low-voltage rail-mounted power supply system and its modular structure into four major modules for easy installation.

[0062] In practical applications, electrical loads include lighting fixtures, cameras, speakers, projectors, etc. When designing or changing the power circuit, only a few fixing and installation operations are needed to complete the installation and adjustment process of the entire low-voltage rail-mounted power supply system and its modular structure. It can be completed without special installation tools.
