[0025] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0026] like Figures 1 to 5 As shown, an emergency evacuation indicator light comprises a connecting shell 1 and an indicator light board 2, wherein the top of the indicator light board 2 is connected to the bottom of the connecting shell 1, and the connecting shell 1 is provided with a rear shell portion 11, and the rear shell portion 11 is hinged with a front cover portion 12 which can be opened or closed by flipping.

[0027] As described above, in this case, a front cover portion 12 that can be flipped to be opened or closed is provided on the connecting shell 1, so that when it is necessary to replace accessories or batteries inside the connecting shell 1, the connecting shell 1 can be directly opened for replacement by flipping the front cover portion 12, without disassembling the entire connecting shell 1, which is more convenient to use and improves maintenance efficiency.

[0028] like Figures 2 to 4 As shown, the rear shell 11 and the front cover 12 are hinged together by a hinge structure, and the hinge structure includes an arc-shaped protrusion 31 formed by bending and extending forward from the front side of the top wall 111 of the rear shell 11, and a first groove 32 provided on the front cover 12 and matching the arc-shaped protrusion 31. The outer surface of the arc-shaped protrusion 31 is a first arc surface 311, and the groove wall of the first groove 32 is provided with a second arc surface 321 that can slide relatively along the first arc surface 311. In this way, the arc-shaped protrusion 31 and the first groove 32 of the hinge structure are arranged in coordination to ensure stable connection and smooth rotation between the rear shell 11 and the front cover 12. Specifically, through the coordination of the first arc surface 311 and the second arc surface 321, the front cover 12 can slide smoothly during the flipping process, thereby ensuring the stability and durability of the structure.

[0029] like Figure 2As shown, the rear shell 11 is provided with a rear side wall 112, the top surface of the rear side wall 112 extends forward to form the top wall 111, and the bottom of the front end surface extends forward to form the first bottom wall 113, and a first accommodating space 114 for installing internal accessories is formed between the top wall 111, the rear side wall 112, and the first bottom wall 113. In this way, the rear shell 11, through the arrangement of its rear side wall 112, the top wall 111 and the first bottom wall 113, forms a first accommodating space 114 for installing internal accessories, providing installation space for accessories inside the device, ensuring that these accessories can be stably placed in the shell.

[0030] like Figure 4 and Figure 5 As shown, in a specific implementation, a limit blocking structure is formed between the first bottom wall 113 and the front cover portion 12 for limiting the angle of the front cover portion 12 when it is closed, and the limit blocking structure includes a first limit wall body 41 extending backward from the rear side of the front cover portion 12, and a blocking structure 42 extending downward from the front end surface of the first bottom wall 113 for blocking the first limit wall body 41.

[0031] The first limiting wall body 41 is provided with a limiting protrusion 411 protruding toward the direction of the blocking structure 42. The blocking structure 42 is provided with a first vertical extension 421 extending downward from the front end surface of the first bottom wall 113, a first longitudinal extension 422 extending backward from the lower end surface of the first vertical extension 421, and a limiting groove 423 formed by being recessed upward from the bottom surface of the first longitudinal extension 422. The limiting groove 423 is used for the limiting protrusion 411 to be limited and swung into it when the front cover 12 is closed. In specific implementation, the limiting protrusion 411 is an arc-shaped protrusion, which is conducive to the front cover 12 being easily buckled and clamped together with the limiting groove 423 when it is closed, ensuring that the front cover 12 will not be easily opened, and playing a good protective role for the internal parts. When it is necessary to open the flip cover to flip open the cover, the buckle can be released with a certain force with the help of a tool and then flip the cover, and the buckle contact is also relatively simple.

[0032] As described above, the first limiting wall 41 and the blocking structure 42 of the limiting blocking structure are arranged so that when the front cover 12 is closed, the first limiting wall 41 and the blocking structure 42 interact with each other to ensure that the front cover 12 can stably stay in the predetermined closed position, which can effectively prevent the front cover 12 from turning over excessively and easily damaging or hitting the indicator light board 2, thereby enhancing the stability and reliability of the emergency evacuation indicator light. The arrangement of the limiting protrusion 411 and the limiting groove 423, on the one hand, is to more accurately define the closing angle of the front cover 12, and on the other hand, is to facilitate the limiting protrusion 411 to swing into the limiting groove 423 when the front cover 12 is closed, thereby ensuring that the front cover 12 can stably stay at the predetermined angle.

[0033] like Figure 2-Figure 4 As shown, in a specific implementation, the bottom surface of the first bottom wall 113 extends downward from the rear half to form a first protrusion 115, the front cover 12 is provided with a front side wall 121 that is opposite to the rear side wall 112 in the closed state, and a second bottom wall 122 that extends backward from the bottom end of the front side wall 121, and a second accommodation space 5 for the top of the indicator light board 2 to be swung in is formed between the front side of the first protrusion 115 and the rear side of the second bottom wall 122. In a specific implementation, a connecting strip groove 1151 is concavely provided on the front side wall of the first protrusion 115, and the indicator light board 2 can be inserted into the connecting strip groove 1151 by a protrusion matching the indicator light of the indicator light board 2, or the indicator light board 2 can be bonded to the front side wall of the first protrusion 115 by gluing. In this way, the first protrusion 115 is provided, which not only provides support for the top of the indicator light board 2, but also forms the second accommodation space 5 together with the second bottom wall 122 of the front cover, so that the indicator light board 2 can be stably installed therein. The second accommodating space 5 provides a space for installing and fixing the indicator light board 2 .

[0034] The first protrusion 115 is a hollow structure, the upper part of the first protrusion 115 is recessed backward to form a first recess 61, a second recess 62 opposite to the first recess 61 is formed between the first bottom wall 113, the first vertical extension 421, and the first longitudinal extension 422, and a first installation groove 6 is formed between the first recess 61, the second recess 62, and the bottom surface of the first bottom wall 113, and a light strip 7 is installed in the first installation groove 6. In this way, the first installation groove 6 is formed between the first recess 61, the second recess 62, and the bottom surface of the first bottom wall 113, providing space for the installation of the light strip 7, and the first installation groove 6 also provides installation space for the wires of the light strip 7, thereby improving the safety of the product. Moreover, the first protrusion 115 is a hollow structure, which can save materials.

[0035] like Figure 2 As shown, the connecting shell 1 is also provided with a left shell part 8 and a right shell part 9 respectively connected to the left and right sides of the rear shell part 11, and the left shell part 8 and the right shell part 9 can completely cover the left and right side surfaces of the connecting shell 1 when the front cover part 12 is closed; the rear shell part 11 is formed with a first through groove 116 extending laterally for screws to pass through at the upper position of the inner wall, and a second through groove 117 extending laterally for screw holes to pass through is formed at the lower position of the inner wall, and the left shell part 8 and the right shell part 9 are fixedly connected to the rear shell part 11 by inserting screws into the first through groove 116 and the second through groove 117 respectively.

[0036] As described above, the arrangement of the left shell portion 8 and the right shell portion 9 makes the connection shell of the entire emergency evacuation indicator light more complete, without exposed parts, and can protect the accessories inside the shell, effectively preventing dust, moisture or other contaminants from entering the interior, reducing the risk of damage to internal accessories, thereby improving the safety of the product. By arranging the first through groove 116 and the second through groove 117 extending laterally on the inner side wall of the rear shell portion 11, the fixing of the left shell portion 8 and the right shell portion 9 is more convenient and quick, and is convenient for future maintenance and replacement. For example, when the light strip 7 needs to be replaced, since the light strip 7 is installed in the first installation groove 6, the user only needs to disassemble the left shell portion 8 / right shell portion 9 for replacement, further improving the efficiency of maintenance and disassembly.

[0037] like Figure 4 and Figure 5 As shown, a raised step portion 118 for limiting the angle of the front cover portion 12 when it is flipped open is provided between the top wall 111 of the rear shell portion 11 and the arc-shaped protrusion 31, and the raised step portion 118 is formed by extending upward from an inner end of the arc-shaped protrusion 31. In a specific implementation, due to the provision of the raised step portion 118, the front cover portion 12 will not flip over when it is flipped open, so as to extend the service life of the product by limiting the flip angle and enhancing the structural stability.

[0038] like Figure 4 As shown, the inner wall of the front cover 12 is formed with reinforcing ribs 123. In this way, the strength and stability of the front cover 12 can be ensured while saving materials.

[0039] As mentioned above, this case protects an emergency evacuation indicator light, and all technical solutions that are the same or similar to this case should be deemed to fall within the scope of protection of this case.
