Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a train ring lamp which is easy to maintain. Background Art

[0002] Light source is a physics term. Some objects in the universe emit light, while others do not. We call objects that emit and are emitting light a light source. The sun, a light bulb, a burning candle, and so on are all light sources. Cars and motor vehicles require light sources for illumination at night, and most currently use lamps.

[0003] The utility model with announcement number CN209856985U discloses an annular light source structure for a vehicle lamp, comprising a bottom edge ring, an LED light board, and a ring cover. The top of the bottom edge ring is fixedly provided with an outer edge ring and an inner edge ring along the circumference. An annular retaining groove is formed between the outer edge ring and the inner edge ring, and the LED light board is positioned within the inner edge ring. The top of the bottom edge ring is provided with a plurality of compression springs equidistantly provided along the circumference. This annular light source structure for a vehicle lamp is conveniently disassembled and maintained by simply removing the connecting screws on the ring cover and the bottom edge ring and separating the retaining grooves and retaining posts on the light board. The LED light board can then be removed, making disassembly simple and time-saving. By placing the light board on the compression springs and squeezing the compression springs, the elastic action of the compression springs can offset some of the force acting on the LED light board when the light board shakes, thereby protecting the LED light board.

[0004] However, during the maintenance of the lamp, firstly, bolts are required to connect the ring cover and the bottom ring together, and secondly, the installation process between the elastic rubber pad and the LED light panel is complicated. Utility Model Content

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Reference Figure 1-7 The utility model is a train ring lamp that is easy to maintain, including a top seat 3 fixedly connected to the train ceiling, a base 2 slidably plugged into the bottom of the top seat 3, a lamp tube 1 fixedly installed on the base 2, and a lamp board 208 electrically connected to the lamp tube 1 is provided inside the base 2. When in use, the LED light board 208 is used for power supply. When repairing, the base 2 and the lamp tube 1 are directly replaced. The base 2 and the top seat 3 are plugged and fixed, which is convenient for disassembly.

[0031] A slide groove 301 is radially machined at the bottom of the top seat 3, and a slider 201 is integrally formed on the top of the base 2, which is slidably plugged into the slide groove 301. When in use, the slider 201 is slid into the slide groove 301, so that the base 2 and the top seat 3 are docked together. When disassembly is required, the base 2 can be pushed in the reverse direction to separate the slider 201 from the slide groove 301. Maintenance and replacement can be achieved without the aid of tools, making maintenance more convenient.

[0032] The chute 301 radially penetrates the top seat 3. Partition plates 302 are welded on both sides of the bottom of the chute 301 along the sliding direction. A limiting groove 303 is provided at one end of the chute 301. The width of the limiting groove 303 is greater than that of the partition plate 302.

[0033] The shape of the slider 201 corresponds to that of the partition 302 , and a limiting block 203 having a shape corresponding to that of the limiting groove 303 is provided at the end of the slider 201 .

[0034] A gap is left between the partition plate 302 and the top wall of the limiting groove 303 . The lateral cross section of the slider 201 is T-shaped, corresponding to the shape of the limiting groove 303 .

[0035] When in use, the slider 201 is inserted into the slide groove 301 from one end of the slide groove 301 located in the limit groove 303, and the slider 201 is slidably connected to the slide groove 301. Finally, the limit block 203 is inserted into the limit groove 303 to prevent the slider 201 from continuing to slide forward and slide out of the slide groove 301, thereby slidingly plugging the base 2 into the bottom of the top seat 3.

[0036] A plug-in groove 304 is processed on the side wall of the limit groove 303, and a plug-in block 204 is provided on the limit block 203 to be plugged into the plug-in groove 304. The plug-in block 204 and the plug-in groove 304 are plugged in along the sliding direction of the slider 201. When the plug-in block 204 is inserted into the plug-in groove 304, the plug-in block 204 and the plug-in groove 304 are detachably plugged in to prevent the base 2 from automatically detaching from the bottom of the top seat 3 and falling out.

[0037] The plug-in block 204 includes a connecting rod 211 fixed to the limit block 203. The end of the connecting rod 211 away from the limit block 203 is connected to a snap-in ball 210. The radius of the snap-in ball 210 is greater than the radius of the connecting rod 211. The connecting rod 211 and the snap-in ball 210 are both hollow structures. Expansion joints 212 are formed on the connecting rod 211 and the snap-in ball 210, so that the snap-in ball 210 and the connecting rod 211 can be retracted toward the middle, thereby reducing the radius of both.

[0038] The plug-in slot 304 is a groove structure with a size corresponding to the connecting rod 211 and the snap-in ball 210. When the snap-in ball 210 is inserted into the plug-in slot 304, the snap-in ball 210 and the connecting rod 211 are reduced through the expansion joint 212, and then the snap-in ball 210 and the connecting rod 211 enter the plug-in slot 304. When the snap-in ball 210 and the connecting rod 211 restore their elastic deformation, the base 2 is detachably fixed on the top seat 3 through the snap-in ball 210 and the plug-in slot 304.

[0039] A lamp board slot 205 is machined at the center of the base 2. A heat sink 206 and a buffer sponge 207 are arranged inside the lamp board slot 205 from bottom to top. A lamp board 208 is clamped inside the buffer sponge 207. The lamp board 208 is electrically connected to the conductive sheet 209.

[0040] The buffer sponge 207 is a hollow ring structure. The lamp board 208 is installed in the middle of the lamp board groove 205 through the buffer sponge 207. The buffer sponge 207 has a shock-absorbing effect on the lamp board 208. At the same time, the heat dissipation plate 206 contacts the lamp board 208 from the bottom. In the case of vibration, it contacts the lamp board 208 to dissipate heat for the lamp board 208.

[0041] Bolt holes 307 are also formed on the top seat 3. When in use, the top seat 3 is first fixed to the ceiling of the train through the bolt holes 307.

[0042] A telescopic slot 305 is formed on the top of the slide 301. A downward-tilted elastic brush piece 306 is located inside the telescopic slot 305. The elastic brush piece 306 is in the shape of a √. A wire 308 is installed on the top of the top seat 3. The elastic brush piece 306 is connected to an external power source through the wire 308.

[0043] A conductive sheet 209 corresponding to the elastic brush sheet 306 is installed on the top of the slider 201. The conductive sheet 209 is electrically connected to the light board 208. When the slider 201 slides into the slide groove 301, the conductive sheet 209 maintains close contact with the elastic brush sheet 306 to supply power to the light board 208.

[0044] Working principle: When in use, fix the top base 3 through the bolt hole 307 at the reserved position on the ceiling of the train compartment, connect the wire 308 to the external power supply, then align the slider 201 with the slide groove 301, and insert the slider 201 into the slide groove 301 to achieve quick installation of the lamp.

[0045] When the base 2 and the lamp tube 1 need to be replaced, push the slider 201 from the end of the slider 201 away from the limit block 203 to push the base 2 out of the top seat 3. Here, the lamp panel groove 209 and the elastic brush piece 306 change from sliding fit to sliding separation, and then reinstall the new base 2 and lamp tube 1, which is convenient and quick.
