Description

Technical Field

[0001] This utility model relates to the field of lighting, and in particular to a railway passenger station grille downlight with a quick-release structure. Background Technology

[0002] Grille downlights are commonly used for lighting ceilings, walls, and other spaces. In railway passenger stations, the ceiling is high off the ground, requiring a special lifting frame to elevate the operator to a higher position before the grille downlights can be installed.

[0003] However, railway passenger stations cover a large area and there are many locations for downlight installation. When using a lifting frame to assist in the installation of downlights, the position of the lifting frame needs to be constantly moved, resulting in low installation efficiency. Furthermore, the grid downlights in railway passenger stations are in a state of continuous illumination and require regular maintenance and replacement. Using a lifting frame to assist operators in climbing to maintain the lights is a high-altitude operation, which is not only inefficient but also poses safety hazards. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a railway passenger station grid downlight with a quick-release structure, which allows operators to replace the downlight from the ground, improves the installation efficiency of the downlight, and avoids the safety hazards caused by working at height.

[0022] Please see Figure 1 This utility model provides a railway passenger station grille downlight 10 with a quick-release structure, which includes: a housing 100, multiple brackets 200, and downlights 300 mounted on the brackets 200. This allows operators to perform the installation of the downlights 300 from the ground via a drone 500.

[0023] Please see Figure 2 and Figure 3 The bracket 200 has a plug-in rod 210, an electrical connector 220, and an unlocking ring 230 at one end away from the housing 100. The electrical connector 220 is located at the end of the plug-in rod 210. Preferably, the diameter of the electrical connector 220 is larger than the diameter of the plug-in rod 210. A dimensional difference exists between the electrical connector 220 and the plug-in rod 210, and the two together form an inverted "T" shape structure for quick connection with the downlight 300.

[0024] Please see Figure 4 A limiting part 211 is provided at the position where the plug rod 210 connects to the electrical connector 220. The unlocking ring 230 is movably provided on the limiting part 211, and an inclined ladder 231 is provided on the side of the unlocking ring 230 away from the electrical connector 220.

[0025] Please see Figure 4 The downlight 300 includes a lamp body 310 and two clips 320. The lamp body 310 has a docking hole 311 and a groove 312 communicating with the docking hole 311. The docking hole 311 is used to accommodate an electrical connector 220. The wall of the docking hole 311 is provided with an electrical terminal, so after the electrical connector 220 extends into the docking hole 311, an electrical connection can be achieved between the housing 100 and the lamp body 310.

[0026] Please see Figure 4 The buckle 320 is movably disposed in the slide groove 312, and a spring 330 is provided between the buckle 320 and the inner wall of the slide groove 312. The spring 330 is used to push the buckle 320 into the mating hole 311 so that the buckle 320 locks the plug rod 210. The inclined ladder 231 is used to guide the buckle 320 back into the slide groove 312 so as to release the connection between the buckle 320 and the plug rod 210.

[0027] The downlights claimed in this application are used in railway passenger stations, where long-term illumination is required. Since these downlights are in continuous operation, malfunctions and damage are inevitable, necessitating periodic replacement. However, the high ceilings in railway passenger stations make replacing downlights inconvenient. This application simplifies the connection between the downlight 300 and the bracket 200, allowing operators to replace the downlight 300 from the ground using a drone. The principle behind the quick connection between the downlight 300 and the bracket 200 is as follows: The housing 100 is installed on the ceiling. At this time, the connection between the target downlight 300 and the bracket 200 is as follows: Figure 4As shown, the plug rod 210 extends into the mating hole 311, the two buckles 320 and the limiting part 211 on the plug rod 210, the unlocking ring 230 is located at the upper end of the buckle 320, and due to the size difference between the electrical connector 220 and the plug rod 210, an inverted "T" shaped structure is formed, the buckle 320 is blocked by the electrical connector 220, so that the downlight 300 is hung on the bracket 200; When performing the task of replacing the downlight 300, the drone 500 is moved below the target downlight 300 and then driven to rise vertically, pushing the lamp body 310 upwards. As the lamp body 310 rises, the latch 320 abuts against the bottom of the unlocking ring 230, generating a lateral thrust that causes the latch 320 to retract into the slide groove 312. After the latch 320 passes the unlocking ring 230, it pops out again. At this point, the latch 320 moves from below the unlocking ring 230 to above it, as... Figure 5 As shown, at this time, the unlocking ring 230 loses the support of the buckle 320 and falls down, and comes into contact with the electrical connector 220.

[0028] Next, the drone 500 is driven to descend. Because the unlocking ring 230 has a ramp 231 on its side away from the electrical connector 220, the latch 320 abuts against the ramp 231 as it descends. Figure 6 As shown, the inclined ladder 231 guides the buckle 320 back into the slide groove 312. Since the unlocking ring 230 is now in contact with the electrical connector 220, the buckle 320, after passing the unlocking ring 230, is contacted by the side wall of the electrical connector 220 and cannot pop out directly. That is, the electrical connector 220 no longer blocks the buckle 320, and the lamp body 310 can continue to descend until the plug rod 210 is completely disengaged from the mating hole 311. Figure 7 As shown; the disassembly of the target downlight 300 is complete.

[0029] After the new downlight 300 is mounted on the drone 500, the drone 500 pushes the downlight 300 upward, causing the connector 210 to enter the docking hole 311. The electrical connector 220 opens the latch 320. During the upward movement of the latch 320, the unlocking ring 230 is lifted. When the lower end of the latch 320 passes the electrical connector 220, the spring 330 pushes the latch 320 to extend in, causing the latch 320 to abut against the limiting part 211. The latch 320 and the electrical connector 220 cooperate to hang the new downlight 300 on the bracket 200. Figure 4 As shown. Simply detach the drone 500 from the downlight 300.

[0030] The railway station grille downlight 10 with a quick-release structure also includes a positioning base 400, which is mounted on the drone 500 and is used to support the lamp body 310.

[0031] As can be seen from the replacement process of the downlight 300 described above, the process of disassembling the old downlight 300 requires applying an axial thrust to the lamp body 310, followed by an axial pull; while the process of installing the new downlight 300 only requires applying an axial thrust to the lamp body 310. Furthermore, there is no need to rotate the lamp body 310 or tighten screws, simplifying the connection between the downlight 300 and the bracket 200. This allows the replacement of the downlight 300 to be carried out using a drone 500, which not only improves the replacement efficiency of the downlight 300 but also avoids the safety hazards associated with working at height.

[0032] Please see Figure 3 Preferably, the electrical connector 220 has an arc surface 221, and the buckle 320 has an inclined portion 321 that matches the arc surface 221. When the inclined portions 321 come into contact with each other, a lateral force is generated, which causes the buckle 320 to overcome the elastic force of the spring 330 and retract into the slide groove 312, making the extension and retraction process of the buckle 320 smoother.

[0033] Please see Figure 1 In one embodiment, the housing 100 is provided with a storage tube 110, and the bracket 200 is telescopically disposed inside the storage tube 110, the length of which can be adjusted according to installation requirements. A wire box 240 is provided on one end of the bracket 200 exposed above the storage tube 110, and a connector 210 is located on the wire box 240, which is used to store wires. The color of the wire box 240 is different from the color of the connector 210, creating a color difference, which facilitates the location of the connector 210 using a camera on the drone 500, further reducing the difficulty of replacing the downlight 300.

[0034] In one embodiment, the buckle 320 has a contact end on the side facing the docking hole 311. The contact end is arc-shaped and is used to abut against the side wall of the plug rod 210.

[0035] In one embodiment, the depth of the mating hole 311 is greater than the length of the insertion rod 210.

[0036] Please see Figure 3 In one embodiment, the plug rod 210 is provided with a shoulder 212, which is used to block the unlocking ring 230. When the downlight 300 is disassembled, the shoulder 212 provides a limit to restrict the sliding range of the unlocking ring 230, ensuring that the buckle 320 can move from below the unlocking ring 230 to above the unlocking ring 230 and successfully complete the unlocking action.

[0037] The above-mentioned railway passenger station grille downlight 10 with quick-release structure has the following beneficial effects: 1. The connection and unlocking process between the downlight 300 and the bracket 200 only requires the application of axial thrust and pull force. The direction of force application is unidirectional. The disassembly and assembly can be completed by simply operating the drone 500 to lift and lower, which simplifies the replacement process of the downlight 300 and helps to improve the maintenance efficiency of the downlight 300. 2. The operator can complete the replacement of the downlight 300 from the ground without having to climb up the platform for high-altitude work, thus avoiding the safety hazards during the replacement of the downlight 300.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
