Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0030] As shown in the drawings, it is a light guide plate 100 of an embodiment of the present application, comprising a light guide plate body 200, a first frame 300 and a second frame 400. Figures 1 to 4 The middle part of the first frame 300 is provided with a first frame opening 301 along the first direction, and a plurality of first clamping portions 310 are provided on the outer side of the first frame opening 301 along the first direction.

[0031] The middle part of the second frame 400 is provided with a second frame opening 401 along the first direction, and a plurality of second clamping groove portions 420 are provided on the outer side of the second frame opening 401 along the first direction.

[0032] The first frame 300 and the second frame 400 are respectively attached to the two opposite surfaces of the light guide plate body 200, and the light guide plate body 200 is located in the mounting opening, one surface of each second clamping groove portion 420 abuts against the light guide plate body 200, and the opposite surface of each second clamping groove portion 420 abuts against one first clamping portion 310, and each first clamping sub-portion 311 is clamped into one second clamping hole 421.

[0033] ​

[0034] In the embodiment, the first frame 301 and the second frame 401 are used for light transmission, and the widths and areas of the first frame 301 and the second frame 401 are equal. Among them, the two opposite surfaces of the light guide plate 100 are light emitting surfaces, the first direction is perpendicular to the light emitting surface of the light guide plate 100, and the second direction is parallel to the light emitting surface. For example, the first fastening part 310 protrudes the first fastening sub-part 311 towards the inner side of the mounting port.

[0035] In the embodiment, the light guide plate body 200 is provided with a diffusing structure, such as a diffusing stripe or a frosted layer. When the light emitted by the lamp bead 520 is incident on the diffusing structure, the diffusing structure reflects the light, so that the light guide plate 100 forms a light emitting effect. In some embodiments, the light emitting surface of the light guide plate body 200 can also be provided with an indication mark, such as an EXIT mark, for example, an indication information of an escaping person and an arrow. The light emitting of the light guide plate body 200 can make the indication mark more clearly displayed.

[0036] In the embodiment, the shape of the light emitting surface is a rectangle, and the shape of the mounting port is a rectangle matching the light emitting surface. The length and width of the mounting port are greater than the length and width of the first frame 301 and the second frame 401, and the area of the mounting port is greater than the area of the first frame 301 and the area of the second frame 401. Therefore, the part from the first frame 301 to the mounting port on the first frame 300 can abut against the edge of one side of the light guide plate body 200, and the part from the second frame 401 to the mounting port on the second frame 400 can abut against the edge of the other side of the light guide plate body 200, thereby forming clamping of the light guide plate body 200.

[0037] In the embodiment, the first frame 300 and the second frame 400 are clamped on both sides of the light guide plate body 200, and the first fastening sub-part 311 is clamped into the second fastening hole 421, so that the first frame 300 and the second frame 400 are fixedly connected. Since the light guide plate body 200 abuts against the side of the second fastening groove part 420 away from the first fastening part 310, the second fastening groove part 420 is supported by the light guide plate body 200 and is not easy to bend, so that the fastening between the second fastening groove part 420 and the first fastening part 310 is more tight, thereby avoiding the bending of the second fastening groove part 420 causing the first fastening sub-part 311 to fall off from the second fastening hole 421, so that the first frame 300 and the second frame 400 are more firmly installed and are not easy to crack, and can better support the light guide plate 100. Therefore, the first frame 300 and the second frame 400 clamp the light guide plate body 200, so that the light guide plate body 200 is fixed, and the light guide plate body 200 reacts on the second fastening groove part 420, which can further enhance the connection stability of the first frame 300 and the second frame 400.

[0038] In one embodiment, please refer to Figures 2 to 4 , the second frame 400 is provided with a plurality of second fastening parts 410 on the outside of the second frame opening 401 in the first direction, the second fastening part 410 is provided with a second fastening sub-part 411 in the second direction, the first frame 300 is provided with a plurality of first fastening groove parts 320 on the outside of the first frame opening 301 in the first direction, the first fastening groove part 320 is provided with a first fastening hole 321 in the second direction, and each second fastening sub-part 411 is clamped into the first fastening hole 321.

[0039] In this embodiment, the second frame 400 is provided with a second fastening part 410, and the second fastening sub-part 411 on the second fastening part 410 is clamped into the first fastening hole 321 of the first fastening groove part 320 on the first frame 300, which can make the connection between the first frame 300 and the second frame 400 more firm.

[0040] In one embodiment, one side of each first fastening groove part 320 abuts against the light guide plate body 200, and the other side of each first fastening groove part 320 abuts against a second fastening part 410 respectively.

[0041] In this embodiment, the light guide plate body 200 abuts against the side of the first fastening groove part 320 which is away from the second fastening part 410, so that the first fastening groove part 320 is supported by the light guide plate body 200 and is not easy to bend, which can make the fastening between the first fastening groove part 320 and the second fastening part 410 more tight, thereby avoiding the first fastening groove part 320 bending and causing the second fastening sub-part 411 to fall off from the first fastening hole 321, and further making the installation of the first frame 300 and the second frame 400 more firm and not easy to crack.

[0042] In one embodiment, a plurality of first fastening parts 310 and a plurality of first fastening groove parts 320 are arranged adjacent to each other, and a plurality of second fastening parts 410 and a plurality of second fastening groove parts 420 are arranged adjacent to each other. In this embodiment, a plurality of first fastening parts 310 are arranged adjacent to each other, and a plurality of first fastening groove parts 320 are arranged adjacent to each other, and the plurality of first fastening parts 310 are located on one side of the plurality of first fastening groove parts 320, a plurality of second fastening parts 410 are arranged adjacent to each other, and a plurality of second fastening groove parts 420 are arranged adjacent to each other, and the plurality of second fastening parts 410 are located on one side of the plurality of second fastening groove parts 420, which can improve the stability of the connection between the first frame 300 and the second frame 400.

[0043] In other embodiments, the first buckling parts 310 and the first buckling groove parts 320 are arranged in a staggered manner, and the second buckling parts 410 and the second buckling groove parts 420 are arranged in a staggered manner, so as to further enhance the stability of the connection.

[0044] In one embodiment, as shown in Figure 5A and Figure 5B , the light guide plate 100 further comprises a lamp plate 500, which is arranged on one side of the mounting opening and is located outside the first frame opening 301 and the second frame opening 401. The lamp plate 500 is provided with lamp beads 520 on the first surface thereof, and the lamp beads 520 face the light guide plate body 200. The lamp plate 500 is provided with support parts 510 protruding from both ends of the first surface thereof, and the thickness of the support parts 510 is greater than that of the lamp beads 520. The support parts 510 abut against the light guide plate body 200, and the second surface of the lamp plate 500 abuts against the second buckling groove parts 420 away from the first buckling parts 310. The first surface and the second surface of the lamp plate 500 are arranged oppositely.

[0045] In this embodiment, the lamp plate 500 is located in the mounting opening but outside the first frame opening 301 and the second frame opening 401, so that the lamp plate 500 can be clamped by the first frame 300 and the second frame 400, and can be prevented from being exposed outside the first frame opening 301 and the second frame opening 401. In this embodiment, the lamp plate 500 abuts against the light guide plate body 200 through the support parts 510, and the lamp plate 500 abuts against the second buckling groove parts 420. Therefore, the first frame 300 and the second frame 400 can be supported by the lamp plate 500, so that the buckling between the second buckling groove parts 420 and the first buckling parts 310 is more compact, and the first frame 300 and the second frame 400 are more firmly installed and are less likely to crack.

[0046] In one embodiment, please refer to Figure 3 and Figure 4 , the length of the second buckling groove parts 420 protruding from the second frame 400 is greater than the length of the first buckling parts 310 protruding from the first frame 300. In this embodiment, the length of the first buckling parts 310 is short and is not easy to bend, which effectively prevents the first buckling sub-parts 311 from falling out of the second buckling holes 421. Although the length of the second buckling groove parts 420 is long, the light guide plate body 200 abuts against the second buckling groove parts 420 to support the second buckling groove parts 420, which prevents the second buckling groove parts 420 from being bent and deformed, thereby further effectively preventing the first buckling sub-parts 311 from falling out of the second buckling holes 421.

[0047] In one embodiment, the first clasp groove 320 protrudes from the first frame 300 by a length greater than the second clasp 410 protrudes from the second frame 400. In this way, the second clasp sub 411 can be effectively prevented from falling out of the first clasp hole 321.

[0048] In one embodiment, please refer to Figures 1 to 4 , a first sub threaded hole 331 is formed at one end of the first frame 300, a second sub threaded hole 431 is formed at one end of the second frame 400, the first sub threaded hole 331 and the second sub threaded hole 431 are combined to form a threaded hole, and a threaded structure is provided on the side wall of the threaded hole.

[0049] In this embodiment, after the first frame 300 and the second frame 400 are connected, the first sub threaded hole 331 and the second sub threaded hole 431 are combined to form a threaded hole with a threaded structure, so that the threaded joint or screw can be easily screwed in to fix the first frame 300 and the second frame 400 on the power supply box of the emergency indicator light 10.

[0050] In one embodiment, as Figure 2 shown, the light guide plate body 200 includes a first plate body 210 and a second plate body 220, the first plate body 210 and the second plate body 220 are aligned and abut each other, the first frame 300 abuts the side of the first plate body 210 away from the second plate body 220, the second frame 400 abuts the side of the second plate body 220 away from the first plate body 210, the first plate body 210 and the second plate body 220 are located in the mounting port, and the edges of the first plate body 210 and the second plate body 220 abut the side of each second clasp groove 420 away from the first clasp 310.

[0051] In this embodiment, the light guide plate body 200 includes a first plate body 210 and a second plate body 220, and the first plate body 210 and the second plate body 220 are respectively provided with light dispersing structures for guiding light. In this way, when the light emitted by the lamp bead 520 is directed to the light dispersing structure, the light dispersing structure reflects the light, thereby forming a light emitting effect of the light guide plate 100. In this embodiment, the first frame 300 and the second frame 400 can effectively clamp the first plate body 210 and the second plate body 220, and the abutment of the first plate body 210 and the second plate body 220 can make the clasp between the second clasp groove 420 and the first clasp 310 more closely, thereby preventing the first clasp sub 311 from falling out of the second clasp hole 421.
