The terms used in the description of the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0044] As Figure 4 shown, the status indicator light 100 claimed in this application is applied to the semi-high platform door of rail transit and is used for detachably connecting with the side box top cover 200 of the semi-high platform door of rail transit.

[0045] As Figures 1 to 3As shown in the figure, the status indicator light 100 provided in this application includes a housing 10, an indicator light body 20, an indicator light base plate 30, and a connecting member 40. The indicator light body 20 is housed in the housing 10, and the light generated when the indicator light body 20 works can be emitted outward through the housing 10. A fixing nut 21 is connected to the indicator light body 20; the indicator light base plate 30 is disposed on the side of the indicator light body 20 facing away from the fixing nut 21 and is connected to the indicator light body 20 for carrying the indicator light body 20; in the thickness direction of the indicator light base plate 30, the connecting member 40 sequentially passes through the connecting plate 210 on the side box top cover 200, the indicator light base plate 30, and the indicator light body 20 and is screwed to the fixing nut 21. Here, the indicator light body 20 can be fixedly connected to the indicator light base plate 30 by glue; the fixing nut 21 is partially embedded in the indicator light body 20 and is bonded to the indicator light body 20, and the assembly connection of the fixing nut 21 on the indicator light body 20 is achieved. It should be noted that the connecting member 40 of this application is configured as a bolt, a screw rod, a screw, etc. The indicator light body 20 includes a mounting plate, and LED lamp beads are integrally assembled on the mounting plate.

[0046] As can be seen from the above, the indicator light base plate 30 is used to carry the indicator light body 20, and the threaded connection between the connecting member 40 and the fixing nut 21 is used to achieve the detachable connection of the status indicator light 100 on the side box top cover 200. This can simplify the structure of the status indicator light 100, and only by installing and removing the connecting member 40, the installation and replacement of the status indicator light 100 on the side box top cover 200 can be achieved. The disassembly and assembly are convenient and time-saving, which can improve the production assembly and daily maintenance efficiency of the rail transit semi-high platform door with the status indicator light 100.

[0047] As Figure 1 、 Figure 3 shown in the figure, an extension boss 31 is provided on the indicator light base plate 30. The extension boss 31 is disposed on the side of the indicator light base plate 30 facing away from the indicator light body 20 and is correspondingly disposed with the connecting member 40; among them, the connecting member 40 passes through the corresponding extension boss 31, and the extension boss 31 is used to abut against the connecting plate 210. That is to say, when the connecting member 40 passes through the connecting plate 210, the indicator light base plate 30, and the indicator light body 20 and is screwed to the fixing nut 21, the extension boss 31 can be used for force transmission between the indicator light base plate 30 and the connecting plate 210 to ensure that the connecting member 40 screwed to the fixing nut 21 can fix the indicator light base plate 30 to the connecting plate 210 and achieve the purpose of assembling and fixing the status indicator light 100 on the side box top cover 200. Here, the extension boss 31 is integrally connected to the indicator light base plate 30.

[0048] It should be noted that since the indicator light base plate 30 and the connecting plate 210 on the side box top cover 200 are separated by an extended boss 31, this can prevent the indicator light base plate 30 from directly abutting against the connecting plate 210, and creates conditions for the subsequent convex eaves 32 on the indicator light base plate 30 to extend into the side box top cover 200.

[0049] Preferably, multiple connectors 40 are provided, allowing the status indicator light 100 to be assembled on the side box top cover 200 via multiple connectors 40. This further improves the assembly stability of the status indicator light 100 on the side box top cover 200. Here, two connectors 40 are provided, spaced apart along the length of the indicator light base plate 30. It is understood that the number of connectors 40 can also be one, three, four, or even more. Furthermore, the placement of the connectors 40 can be tailored to specific needs, which will not be elaborated upon here.

[0050] like Figure 2 、 Figure 3 As shown, the indicator light base plate 30 is provided with a protruding eave 32, which is disposed on a side of the indicator light base plate 30 facing away from the indicator light body 20. The protruding eave 32 is configured to extend into the side box top cover 200, and the upper surface 321 of the protruding eave 32 abuts against the lower surface 201 inside the side box top cover 200. Here, the upper surface 321 of the protruding eave 32 is configured to conform to the lower surface 201 of the side box top cover 200. In other words, when the status indicator light 100 is to be assembled to the side box top cover 200, the abutment between the upper surface 321 of the protruding eave 32 and the lower surface 201 of the side box top cover 200 serves as a guide for determining the position of the status indicator light 100 on the side box top cover 200. This not only facilitates the assembly of the status indicator light 100 on the side box top cover 200, but also ensures a tight fit between the status indicator light 100 and the side box top cover 200, providing a waterproof and dustproof effect.

[0051] like Figure 3 As shown, the indicator light base plate 30 is at least partially housed within the housing 10 and is detachably connected to the housing 10. In one embodiment, the indicator light base plate 30 can cover and protect the indicator light body 20 housed within the housing 10. The protruding eaves 32 provided on the indicator light base plate 30 extend into the side box top cover 200 and abut against the lower surface 201 inside the side box top cover 200. In addition, the detachable connection between the indicator light base plate 30 and the housing 10 allows the housing 10 to be replaced independently if damaged, thereby reducing maintenance costs.

[0052] like Figures 1 to 3As shown, one of the indicator light base plate 30 and the housing 10 is provided with a card slot 11, and the other forms a protruding buckle 33. The buckle 33 can be engaged with the card slot 11 to achieve detachable connection between the indicator light base plate 30 and the housing 10, so as to facilitate the disassembly and assembly of the indicator light base plate 30 in the housing 10. Here, the buckle 33 is provided on the indicator light base plate 30, and the card slot 11 is provided in the housing 10. It can be understood that in other embodiments, the buckle can also be provided in the housing 10, and the card slot is provided on the indicator light base plate 30; or, the indicator light base plate 30 can also be connected to the inside of the housing 10 by bonding.

[0053] Preferably, as Figure 3 shown, the outer peripheral wall 301 of the indicator light base plate 30 abuts against the first inner peripheral wall 101 of the housing 10; wherein, the buckle 33 is provided on one side of the indicator light base plate 30 facing the indicator light body 20 and protrudes partially outward relative to the outer peripheral wall 301 of the indicator light base plate 30, so as to improve the assembly sealing performance when the indicator light base plate 30 is assembled in the housing 10. It should be noted that when the indicator light base plate 30 is snapped into the housing 10, the elastic deformation of the buckle 33 can be utilized to enable the buckle 33 to be smoothly engaged with the card slot 11 on the housing 10.

[0054] Preferably, the indicator light base plate 30 and the housing 10 are also adhesively sealed with glue (not shown in the figure), which can not only ensure the sealing performance when the indicator light base plate 30 is assembled in the housing 10, but also play a role in waterproof protection for the indicator light body 20.

[0055] In summary, the overall status indicator 100 of the present application can be detachably connected to the connecting plate 210 of the side box top cover 200 through the connecting member 40, and the installation and replacement of the overall status indicator 100 on the side box top cover 200 can be realized, and the disassembly and assembly are convenient and time-saving; by using the snap connection between the indicator light base plate 30 and the housing 10, the indicator light base plate 30 and the indicator light body 20 as a whole can be disassembled and assembled with the housing 10. When the housing 10 is damaged, the housing 10 can be replaced separately to solve the problem, which can improve the daily maintenance efficiency of the status indicator 100. In addition, the status indicator 100 of the present application uses the indicator light base plate 30 to carry the indicator light body 20, and at the same time, uses the indicator light base plate 30 to realize the installation and replacement of the overall status indicator 100 on the side box top cover 200, or separately realize the replacement of the housing 10, which plays a role in simplifying the structure of the status indicator 100.

[0056] As Figure 4As shown, the present application further provides a semi-height platform door for rail transit, including a side box top cover 200, a fixed side box 300, a sliding door 400, and the above-mentioned status indicator light 100. The side box top cover 200 is fixedly installed at the top of the fixed side box 300, and the sliding door 400 is slidably arranged inside the fixed side box 300. Among them, the status indicator light 100 is detachably connected to the side box top cover 200.

[0057] As Figure 4 shown, a connecting plate 210 is arranged inside the side box top cover 200. A connecting member 40 passes through the connecting plate 210 and abuts against the connecting member 40, so as to meet the use requirements for the assembly and fixation of the status indicator light 100 on the side box top cover 200. Here, upper flanges 211 and lower flanges 212 respectively extend from the upper and lower ends of the connecting plate 210. The upper flanges 211 and the lower flanges 212 are bent and extended towards the inside and outside of the side box top cover 200 respectively. The upper flanges 211 and the lower flanges 212 respectively abut against the second inner peripheral walls 202 on the upper end face of the inner cavity of the side box top cover 200 and the second inner peripheral walls 202 on the lower end face of the inner cavity of the side box top cover 200, and are respectively welded to the corresponding second inner peripheral walls 202. In one embodiment, the upper flanges 211 and the second inner peripheral walls 202 on the upper end face of the inner cavity of the side box top cover 200 form an up-and-down abutment, and the lower flanges 212 and the end edges of the second inner peripheral walls 202 on the lower end face of the inner cavity of the side box top cover 200 abut to form a horizontally flush welding structure. Of course, in other embodiments, the upper flanges 211 and the lower flanges 212 can abut against the corresponding second inner peripheral walls 202 up and down to form an up-and-down corresponding welding structure, or can both abut against the end edges of the corresponding second inner peripheral walls 202 to form a horizontally flush welding structure. It should be noted that the lower surface 201 of the above-mentioned side box top cover 200 is arranged on the second inner peripheral wall 202 of the side box top cover 200.
