Description

Technical Field

[0001] The present invention relates to the technical field of lighting equipment, and in particular to a magnetic track lighting equipment. Background Art

[0002] With the development of lighting technology, track lighting systems have become widely used in various places such as commercial exhibition halls, art galleries, and office spaces due to their advantages such as flexible installation, adjustable angles, and easy replacement. Traditional track lighting equipment usually uses a mechanical snap-on structure or plug-in rail system to achieve the installation and electrical connection of the lamps on the track.

[0003] In the prior art, common track lighting systems primarily consist of a track body, a power rail, a lamp body, and a connection structure. Lamp installation typically relies on a mechanical snap-fit ​​rail-mounted connector. Users slide the connector along the rail into place, then secure it electrically and physically by rotating, snapping, or screwing it in place.

[0004] However, the above structure has the following deficiencies in practical applications: The installation process is complicated: Traditional lighting installation often requires both hands to operate the snap-on structure, or the use of tools to complete the rotation or tightening action, which is time-consuming and not user-friendly for non-professionals, especially when installing at high altitude or in large quantities. The efficiency is low.

[0005] Conductive structure is exposed and contact is unstable: The electrode contact ends of some devices are exposed to the outside and are easily affected by dust, oxidation, etc., resulting in poor contact, which in turn affects the working stability and safety of the lamp.

[0006] Lack of a reliable locking mechanism: Some lamps with plug-in structures rely solely on the friction of sliding into the guide rail or the elastic structure to maintain their position. They are prone to falling off under vibration or accidental collision conditions, posing a major safety hazard.

[0007] The electrical connection lacks dynamic adjustment capabilities: When adjusting the position of a lamp by sliding it on a track, existing technology usually requires power to be turned off before moving it. During the sliding process, power cannot be continuously supplied, affecting the real-time and continuity of the system adjustment.

[0008] Therefore, there is an urgent need for a magnetic track lighting device with a simple structure, convenient installation, stable contact and a safety locking function to solve the problems of cumbersome installation, unstable connection and lack of safety guarantee in the existing technology.

[0009] The present invention is precisely aimed at the above-mentioned problems. Through the optimized coordination of the magnetic suction component and the track structure, a modular sliding seat with magnetic feet, electrode contacts, control rods and locking blocks is designed, which realizes the rapid adsorption, reliable conductivity and firm locking of the lighting fixture, thereby effectively overcoming various defects in the existing technology and improving the practicality and safety of the lighting system. Summary of the Invention

[0010] Existing track lighting systems often use snap-on or plug-in structures, mechanically connecting the spotlights to the track and providing power via sliding contacts. However, these structures present practical challenges such as cumbersome installation, unstable contact, easy detachment of the lamps, and poor sliding power supply. These issues make them difficult to meet the demands of high-frequency adjustments and rapid lighting deployment. Therefore, there is an urgent need for track lighting systems with a simplified structure, efficient installation, stable electrical connections, and automatic locking capabilities to enhance overall user experience and operational safety.

[0011] The present invention proposes a magnetic track lighting device, which realizes structural locking and electrical conduction through the coordinated design of the magnetic attraction component and the sliding conductive mechanism, combined with the control mechanism, thereby improving the safety, convenience and stability of the lighting system.

[0012] The present invention provides a magnetic track lighting device, comprising a track body, a spotlight body, and a magnetic seat assembly. The surface of the track body is provided with a slide groove, a slot, and a locking groove, and a three-way power supply structure is arranged inside, including a positive electrode bar, a negative electrode slot, and a control electrode slot. The magnetic seat assembly includes a sliding seat, a plate seat, a control rod, and a locking block. The sliding seat is provided with a plurality of magnetic feet, and the lower portion of the magnetic feet is provided with an electrode contact for contacting the positive electrode bar. The control rod drives the locking block to slide vertically along the ear slot, so that the spring bar electrode on it contacts the negative electrode slot and the control electrode slot, thereby achieving a three-pole conductive connection and structural locking. The input ends of the positive electrode bar, the negative electrode slot, and the control electrode slot are electrically connected to a power box, and the power box is adapted to the power of the spotlight body.

[0013] After the spotlight body is inserted into the electrical interface of the magnetic base group through the plug connector, power conduction and lighting operation can be achieved. The magnetic track lighting equipment includes a track body, a spotlight body and a magnetic base group. The surface of the track body is provided with a slide rail groove, and its surface is provided with multiple slots and locking grooves. The slots and locking grooves are arranged alternately in a straight line direction. The inside of the slide rail groove is provided with a positive electrode bar, a negative electrode groove and a control electrode groove. This structure replaces the traditional mechanical clamping method with a magnetic method to achieve rapid adsorption and positioning of the spotlight, improve installation efficiency, and reduce dependence on installation tools and space. An angle bracket is rotatably installed on the surface of the spotlight body, and a plug connector is provided on the surface of the angle bracket for electrical connection with the electrical interface of the magnetic base group. This structure realizes the lighting angle adjustment function through the design of a rotatable angle bracket. At the same time, the plug connector connection is simple and reliable, and convenient for quick plug and unplug operations.

[0014] In a preferred example, the magnetic seat group includes a sliding seat, a connecting plate seat, a control rod and several magnetic feet. The magnetic feet are evenly distributed on the surface of the sliding seat, and the spacing between them matches the spacing of the slots. The sliding seat is provided with a guide seat for the lateral sliding of the control rod. The surface of the sliding seat is also provided with an ear slot, and the locking block can be slidably installed inside the ear slot.

[0015] Specifically, the magnetic foot forms a magnetic fit with the track slot / locking groove to achieve rapid adsorption and positioning, while the control rod links the locking block mechanism to achieve mechanical locking to prevent the lamp from shifting or falling, thereby improving overall safety of use.

[0016] In a preferred example, a spring bar electrode is provided on the surface of the locking block, the top and side of which are in contact with the negative electrode slot and the control electrode slot inside the track respectively, an inclined hole groove is provided on the surface of the control rod, and the sliding pin is sleeved in the inclined hole groove, so that the lateral movement of the control rod drives the locking block to slide vertically.

[0017] Specifically, the structure utilizes an inclined hole linkage structure so that vertical locking and conductive contact can be achieved with one lateral action, simplifying the operating process and improving structural efficiency and reliability.

[0018] In a preferred example, the magnetic foot is provided with a plurality of permanent magnets arranged in a circumferential direction, and an electrode contact is provided at the center thereof for sliding contact with the positive electrode bar; the electrode contact is preferably in the form of a spherical protrusion to enhance contact reliability.

[0019] Specifically, the permanent magnet provides sufficient adsorption force, and the electrode contact piece maintains stable contact with the guide rail conductive strip, which can continuously supply power even in fine-tuning or sliding states, effectively preventing lighting interruptions caused by poor electrical contact.

[0020] In a preferred example, the slot is a circular hole structure, the inner diameter of which matches the diameter of the magnetic foot, and the width of the locking slot is smaller than the diameter of the magnetic foot. When the magnetic foot slides above the locking slot, a limiting structure can be formed to enhance stability.

[0021] Specifically, the combination of the circular hole slot and the locking slot not only ensures the rapid placement of the magnetic component, but also forms a secondary limiting structure, thereby improving the positioning accuracy and anti-falling ability of the lamp on the track.

[0022] In a preferred example, the sliding foot on the control rod slides with the guide slide seat to achieve lateral movement guidance. An elastic top bead is provided on the top of the control rod, and a plurality of positioning holes are provided at the bottom of the sliding seat to achieve structural positioning.

[0023] Specifically, the guiding and positioning structure improves the operating accuracy, avoids the control rod from accidentally sliding or over-slipping, and enhances the structural stability and user operating experience.

[0024] In a preferred example, the connecting plate seats are symmetrically arranged on both sides of the bottom of the sliding seat, and an electrical interface is provided on its surface. A plurality of electrode pins are arranged inside the electrical interface, which are electrically connected to the electrode contacts and the spring bar electrodes respectively.

[0025] Specifically, the dual-interface setting enhances installation adaptability and electrical connection redundancy, and spotlights can be installed in any direction or dual spotlights can be installed.

[0026] The beneficial effects achieved by the present invention are: 1. In the present invention, the magnetic feet cooperate with the slots / locking grooves of the track body, and the permanent magnet and electrode contact structure design achieves rapid adsorption and stable installation of the lighting device on the track, greatly simplifying the installation steps of traditional lighting tracks and improving installation efficiency and flexibility.

[0027] 2. In the present invention, a sliding structure of the control rod and the locking block is provided, and a vertical locking action is achieved through the linkage of the inclined hole groove, which not only enhances the mechanical stability of the magnetic connection, but also avoids the loosening or falling of the lamp during use, thereby improving the safety of use.

[0028] 3. In the present invention, a three-way conductive structure (positive electrode strip, negative electrode slot, and control electrode slot) is used in conjunction with elastic electrode strips and electrode contacts to achieve a sliding conductive connection, effectively ensuring the power-on reliability of the spotlight and supporting the maintenance of electrical connection in the sliding state, providing guarantees for the adjustability and stability of the lighting system.

[0031] To make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0032] It is to be understood that these descriptions are illustrative only and are not intended to limit the scope of the invention.

[0033] A magnetic track lighting device provided by some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0034] Combine Figure 1-Figure 7 As shown, the present invention provides a magnetic track lighting device, including a track body 100, a spotlight body 200 and a magnetic seat group 300, a slide rail groove 110 is provided on the outer surface of one side of the track body 100, and the outer surface of the track body 100 is also provided with a plurality of slots 101 and locking grooves 102, and the plurality of slots 101 and locking grooves 102 are alternately arranged along the length direction of the track; the inner side of the slide rail groove 110 is sequentially provided with a positive electrode bar 111, a negative electrode groove 112 and a control electrode groove 113; the input ends of the positive electrode bar 111, the negative electrode groove 112 and the control electrode groove 113 are electrically connected to a power box 400, and the power box 400 is adapted to the power of the spotlight body 200.

[0035] The spotlight body 200 is rotatably mounted with a corner bracket 210, which is disposed on the upper portion of the spotlight body 200. A plug connector is disposed on the upper surface of the corner bracket 210 for electrically connecting to the electrical interface 321 in the magnetic base assembly 300, thereby directing electrical energy to the light-emitting module within the spotlight body 200.

[0036] The magnetic seat assembly 300 includes a sliding seat 310 , a plate seat 320 , a control rod 330 and a locking block 340 .

[0037] like Figure 5 As shown, a plurality of magnetic feet 350 are fixedly mounted on the upper surface of the sliding seat 310, and the spacing between adjacent magnetic feet 350 matches the spacing between adjacent slots 101. The magnetic feet 350 are preferably disc-shaped, with multiple permanent magnets 351 evenly distributed in the circumferential direction embedded in their lower surface. A spherical protrusion-shaped electrode contact 352 is provided at the center of the bottom, which is used to slide in contact with the positive electrode bar 111 inside the track body 100 to achieve a conductive connection.

[0038] A guide slide 311 is provided on the side of the sliding seat 310 for horizontal sliding installation of the control rod 330. The sliding end of the control rod 330 is connected to a sliding foot 331, which slides in conjunction with the guide slide 311 to guide the lateral movement of the control rod 330. Furthermore, an elastic top bead is provided on the top of the control rod 330, and a plurality of positioning holes are provided on the bottom surface of the sliding seat 310 for engaging with the elastic top bead to ensure that the control rod 330 is firmly positioned in the predetermined position.

[0039] The other surface of the sliding seat 310 is provided with a vertically arranged ear-insertion slot 312, and the locking block 340 can slide vertically along the ear-insertion slot 312. To achieve this sliding function, the control rod 330 is provided with an inclined slot 332. A sliding pin is fixed to the bottom of the locking block 340 and inserted into the inclined slot 332. When the control rod 330 moves laterally within the guide slide 311, the sliding pin moves along the inclined slot 332, thereby driving the locking block 340 to move up and down along the ear-insertion slot 312, switching between the locked and released states.

[0040] Two sets of spring-loaded electrodes 341 are located on the top and sides of the locking block 340. These electrodes 341 are preferably bow-shaped and made of an elastic conductive material. When the locking block 340 is in the locked position, the spring-loaded electrodes 341 on the top surface slide into contact with the negative electrode slot 112 and the control electrode slot 113 within the rail body 100, respectively, thereby achieving complete conduction of the three-pole power supply.

[0041] like Figure 6 As shown, the magnetic foot 350 is made of insulating material, and its bottom electrode contact piece 352 is located on the central axis and protrudes outward in a spherical shape to ensure stable sliding contact with the positive electrode bar 111 to avoid electrical connection interruption due to displacement.

[0042] like Figure 5 、 Figure 6 As shown, the connecting plate base 320 is installed at the bottom of the sliding base 310, arranged symmetrically on both sides, with two groups in total. The surface of the connecting plate base 320 is provided with an electrical interface 321. The internal structure of the electrical interface 321 is equipped with a plurality of electrode pins, which are electrically connected to the electrode contacts 352 on the magnetic foot 350 and the spring electrode 341 on the locking block 340, forming a complete power supply circuit. The plug connector on the spotlight body 200 is connected to the electrical interface 321 to realize power supply.

[0043] Furthermore, if Figure 4As shown, the slot 101 is a through-type circular hole, and its inner diameter is consistent with the diameter of the magnetic foot 350 to ensure that the magnetic foot can be pressed vertically and fit and provide positioning guidance; the locking groove 102 is a non-through slit-shaped opening, and its width is smaller than the diameter of the magnetic foot 350, which is used to cooperate with the bottom of the magnetic foot to clamp and position, and can form a mechanical limit when the magnetic foot slides to the top of the locking groove, thereby enhancing the magnetic adsorption force and preventing lateral sliding.

[0044] During use, the user places the magnetic base assembly 300 over the slot 101 or locking slot 102 of the track body 100, allowing the magnetic foot 350 to adhere to the track surface. The user then pushes the control rod 330 to slide horizontally along the guide slide 311, driving the locking block 340 to slide vertically down the ear slot 312, thereby pressing the spring-loaded electrode 341 into the negative electrode slot 112 and the control electrode slot 113, completing the three-pole electrical connection and structural locking. Finally, the spotlight body 200's plug connector is inserted into the electrical interface 321 to power on the spotlight.

[0045] The working principle and use process of the present invention: 1. Working principle: The present invention is based on the combined principle of magnetic connection + sliding conduction + mechanical locking to achieve rapid installation, positioning and power supply of the spotlight on the track.

[0046] The track body 100 is provided with a positive electrode bar 111, a negative electrode slot 112 and a control electrode slot 113 inside, which serve as three power supply conductors; the surface is provided with a slot 101 and a locking slot 102 for positioning and fixing the magnetic foot 350.

[0047] A plurality of magnetic feet 350 are installed on the sliding seat 310, and the bottom of the magnetic foot 350 contains a permanent magnet sheet 351, which cooperates with the slot 101 or the locking groove 102 of the track to achieve pre-adsorption and fixation, and can be used in practical scenarios of daily quick disassembly and assembly; furthermore, in long-term positioning, one end of the magnetic seat group 300 can be slid horizontally so that the bottom surface of the magnetic foot 350 fits with the top surface of the locking groove 102, and the control rod 330 is pushed horizontally to push the locking block 340 to slide up and down, so that the locking block 340 vertically enters the inner side of the slide rail groove 110 and abuts against the top surface of the slide rail groove 110 to increase the friction effect, thereby preventing the magnetic seat group 300 from sliding horizontally, and realizing long-term locking of the magnetic seat group 300 and the track body 100.

[0048] Each magnetic foot 350 is provided with an electrode contact 352 at its center, which achieves electrical conduction by elastically contacting the surface of the positive electrode bar 111 in the track. The spring electrode 341 provided on the locking block 340 contacts the negative electrode slot 112 and the control electrode slot 113 in the track respectively, ensuring three-way electrical connection. The lateral sliding of the control rod 330 pushes the locking block 340 to slide up and down, thereby achieving the attachment / detachment of the magnetic foot 350 and the sliding connection / disconnection of the spring electrode 341 .

[0049] Electrical connection and lighting power supply: The electrical interface 321 on the connecting plate seat 320 is electrically connected to the plug connector on the spotlight body 200, conducting the power supply between the magnetic seat group 300 and the spotlight. The spotlight body 200 can be installed on either side through the connecting plate seats 320 on both sides.

[0050] When the magnetic foot 350 contacts the positive electrode strip 111 and the spring electrode 341 contacts the negative electrode slot 112 and the control electrode slot 113 , a complete circuit is formed and the spotlight can work normally.

[0051] 2. Usage process: Pre-installation stage: The track body 100 is fixedly installed on the ceiling or wall, and the track is connected to the power box 400 to supply power to the track conductive structure.

[0052] Spotlight installation steps: Align the magnetic foot 350 on the magnetic base assembly 300 with the slot 101 on the track surface; adsorb the magnetic foot 350 on the slot 101 or the locking groove 102 through magnetic force; Manually push the control rod 330 to drive the locking block 340 to slide vertically along the ear slot 312, so that the spring electrode 341 is pressed into the negative electrode slot 112 and the control electrode slot 113 respectively, achieving electrode contact and locking; insert the plug connector of the spotlight body 200 into the electrical interface 321 on the connecting plate seat 320 to complete the connection with the power supply.

[0053] Adjustment and disassembly: The control rod 330 can be pushed in the reverse direction to release the lock, and the position of the spotlight can be fine-tuned by sliding the magnetic base assembly 300 on the track; when disassembly is required, the control rod 330 can be pushed in the reverse direction to release the lock, and the plug connector can be pulled out to remove the lamp.
