[0039] like Figures 1 to 10 As shown, the present application provides an underground sound and light alarm signal device, which includes a shell 1, a sounding part 2, a power supply assembly 3 and a light-emitting part 4; the shell 1 is provided with a accommodating cavity, the bottom of the shell 1 has a sound hole 11 connected to the accommodating cavity, and the shell 1 is provided with a control key 5; the sounding part 2 is fixed in the accommodating cavity, the sounding part 2 covers the sound hole 11, and the sounding part 2 transmits sound through the sound hole 11; the power supply assembly 3 is fixed in the accommodating cavity, and the power supply assembly 3 is arranged above the sounding part 2; the light-emitting part 4 is arranged in the accommodating cavity and fixed on the power supply assembly 3, and at least the part of the shell 1 corresponding to the light-emitting part 4 can transmit light; the control key 5 controls the connection between the sounding part 2 and the light-emitting part 4; the power supply assembly 3 electrically connects the sounding part 2 and the light-emitting part 4.

[0040] The above-mentioned underground sound and light alarm signal device has a light-emitting component 4 and a sound-emitting component 2. When an alarm operation is required, the underground sound and light alarm signal device can be controlled by the control key 5 to perform a dual sound and light alarm, thereby providing an effective warning in the construction work area and reducing the safety hazards of traditional alarm devices; at the same time, the above-mentioned underground sound and light alarm signal device is stacked layer by layer, making the internal structure more compact, reducing the overall size, and making it convenient for miners to carry.

[0041] like Figure 3 As shown, in some embodiments, the housing 1 includes a main shell 12 and a cover shell 13. Both the main shell 12 and the cover shell 13 have slot-shaped structures, with the slots of the main shell 12 corresponding to the slots of the cover shell 13. The main shell 12 and the cover shell 13 are detachably connected, enclosing the aforementioned accommodating chamber. In the current embodiment, the main shell 12 and the cover shell 13 are provided with mutually cooperating threads, allowing the main shell 12 and the cover shell 13 to be threadedly connected. To further enhance the sealing of the connection between the main shell 12 and the cover shell 13, a sealing ring 20 is interposed between the main shell 12 and the cover shell 13. Due to the complex environment under the mine, in the current embodiment, to enhance the strength of the housing 1, the main shell 12 and the cover shell 13 may be made of, but are not limited to, explosion-proof PC material to improve the overall drop resistance of the housing 1. Furthermore, to facilitate portability and enhance comfort, the housing 1 and the cover body are rounded in shape, with chamfered corners. In other alternative embodiments, the main shell 12 and the cover shell 13 may also be connected by, but are not limited to, bonding or snapping.

[0042] like Figure 5 As shown, in some embodiments, the sound-emitting component 2 is a speaker. The inner bottom of the main housing 12 is provided with a recess 121, and the sound hole 11 is formed at the bottom of the recess 121. The speaker is embedded in the recess 121. Furthermore, the speaker is bonded to the bottom of the recess 121, thereby reducing the possibility of debris or moisture entering the housing 1 through the sound hole 11 and extending its service life. To enhance structural strength, the inner bottom of the main housing 12 is provided with a plurality of reinforcing ribs 122 around the recess 121.

[0043] like Figure 4 and Figure 5 As shown, in some embodiments, the power supply assembly 3 is arranged above the sounding member 2 and is fixedly connected to the main housing 12. In the current embodiment, the inner bottom of the main housing 12 is provided with a first connecting column 123, and the top of the first connecting column 123 is provided with a first connecting hole, as shown in FIG. Figure 6As shown, the power supply assembly 3 includes a power supply housing 31 and a battery pack 32. The battery pack 32 is disposed within the power supply housing 31 and electrically connects the sound-generating element 2 and the light-generating element 4 to provide electrical energy. The power supply housing 31 is provided with first connecting pins 312 corresponding to the first connecting posts 123. Each first connecting pin 312 has a through-hole through which a connecting member passes to connect to the first connecting hole of the first connecting post 123, thereby securing the power supply assembly 3 to the main housing 12. In some embodiments, four first connecting posts 123 are provided, corresponding to four first connecting pins 312, to provide a more stable secure attachment of the power supply assembly 3. For example, the first connecting holes may be, but are not limited to, threaded holes, and the connecting members may be, but are not limited to, bolts or screws. In the current embodiment, the power supply housing 31 is open on the side away from the sound-generating element 2 to facilitate assembly of the battery pack 32. To enhance the sealing of the power supply assembly 3, the power supply housing 31 is filled with a gel to seal the battery pack 32 within the housing 31.

[0044] What needs to be explained here is that Figure 7 As shown, a recessed groove 311 is provided on the side of the power supply shell 31 facing the sound-emitting part 2, so that part of the sound-emitting speaker can be embedded in the recessed groove 311. On the one hand, the size of the overall device in the height direction can be further reduced; on the other hand, the sound-emitting speaker can be further limited to improve the stability of the assembly.

[0045] It is understandable that if Figure 6 As shown, the underground sound and light alarm signal device also includes a control panel 7. The sounding element 2 and the light-emitting element 4 are connected to the battery pack 32 via the control panel 7. The control key 5 is also controlled by the control panel 7 to connect the sounding element 2 and the light-emitting element 4. The control panel 7 is a common component in electrical tools and will not be described in detail here. To further reduce the size of the overall device, the control panel 7 is disposed within the power supply housing 31. The power supply housing 31 is provided with a socket into which the control panel 7 is inserted. The control panel 7 and the battery pack 32 are enclosed within the power supply housing 31.

[0046] like Figure 1 、 Figure 2 as well as Figure 4 As shown, the control key 5 is set on the main shell 12, and a second adapter plate 30 connected to the control key 5 is set in the main shell 12. The second adapter plate 30 is connected to the control panel 7 to realize circuit switching. In the current embodiment, the control key 5 includes a sound control key 51 and a light control key 52. ​​The sound control key 51 controls the sound component 2, and the light control key 52 can control the light component 4. Therefore, different control keys 5 can separately control the start, stop, and mode switching functions of the sound component 2 and the light component 4. For example, Figure 4 and Figure 5As shown, the main housing 12 is also provided with a second connecting post 124, which has the same structure as the first connecting post 123. The first adapter plate 8 is also provided with a through-hole, and a connector connects the first adapter plate 8 to the second connecting post 124. Furthermore, the main housing 12 is also provided with a light guide 40, which is connected to the second adapter plate 30, so that the different colors of the light guide 40 can display the power level. The light guide 40 is also a common structure for displaying power level in the prior art, and its details will not be repeated here.

[0047] The main shell 12 is also provided with a charging component 6, which is electrically connected to the power supply assembly 3, so that the battery pack 32 is charged through the charging component 6. A third adapter plate 50 is also provided in the main shell 12, and the third adapter plate 50 is connected to the control panel 7. The charging component 6 is connected to the control panel 7 through the third adapter plate 50. In one embodiment, the charging component 6 adopts a magnetic charging component; in another alternative embodiment, the charging component 6 can also adopt a charging method such as a USB, TYPEC port, etc. In the current embodiment, the charging component 6 and the control key 5 are arranged on opposite sides of the main shell 12, so as to reduce interference.

[0048] The main housing 12 is also provided with a data transmission connector 60. A fourth adapter plate 80 is disposed within the main housing 12 and is connected to the control panel 7. The data transmission connector 60 is connected to the fourth adapter plate 80, thereby enabling connection to electronic devices such as mobile phones, tablets, and computers via the data transmission connector 60. This allows for replacement of the control logic programs stored in the control panel 7 for the light-emitting element 4 and the sound-emitting element 2. The main housing 12 is also provided with a shielding cover 70 that shields the data transmission connector 60, minimizing the risk of damage.

[0049] It should be noted here that the main shell 12 has mounting holes corresponding to the control keys 5 , the data transmission connector 60 and the charging component 6 , and the data transmission connector 60 and the charging component 6 are sealed on the main shell 12 by silicone glue.

[0050] like Figure 4 and Figure 6 As shown, in some embodiments, a second connecting pin 313 is provided on the power supply housing 31, and the second connecting pin 313 is provided with a second connecting hole. The underground sound and light alarm signal device also includes a first adapter plate 8, which is provided on the power supply housing 31 and also provided with a through hole. The connecting member passes through the through hole and connects to the second connecting hole, thereby fixing the second adapter plate 30 to the power supply housing 31. The light-emitting element 4 is connected to the second adapter plate 30, and the second adapter plate 30 provides a placement position and an electrical connection position for the light-emitting element 4. For example, the connecting member can also be a bolt or a screw, and the second connecting hole is a screw hole.

[0051] In some embodiments, the light-emitting element 4 has multiple light-emitting surfaces, thereby expanding the light-emitting area and avoiding the occurrence of blind spots. In the current embodiment, the light-emitting element 4 is surrounded by multiple LED light source panels, and the LED light source panels have pins, which are plugged and connected to the first adapter board 8 through the pins for easy installation. Exemplarily, three LED light source panels are provided, and the three LED light source panels are arranged in a triangle. In order to ensure the lighting effect, the cover 13 is light-transmissive, thereby ensuring the light divergence effect.

[0052] like Figure 1 As shown, in some embodiments, the shell 1 includes a baffle shell 14, which is arranged on the main shell 12, and the baffle shell 14 is arranged on the side of the main shell 12 away from the cover shell 13. The baffle shell 14 covers the sound hole 11, and a plurality of transparent windows 141 are arranged circumferentially around the baffle shell 14. The plurality of transparent windows 141 are arranged circumferentially around the baffle shell 14, so that when the underground sound and light alarm signal device is placed, the baffle shell 14 can be placed in a fixed position so that the sound transmitted from the sound hole 11 can be dispersed to the surroundings through the transparent windows 141, reducing obstruction and transmitting sound information in time. Specifically, a third connecting hole is provided on the main shell 12, and a through hole is provided on the baffle shell 14. The connecting member passes through the through hole and is connected to the third connecting hole to fix the baffle shell 14 to the main shell 12. For example, the third connecting hole is a screw hole, and the connecting member can also be, but is not limited to, bolts or screws. In order to facilitate carrying, the cross-section of the cover shell 13 is circular, and the cover shell 13 can also be made of explosion-proof PC material. Further, as Figure 8 and Figure 9 As shown, the baffle shell 14 includes a baffle shell body 142, the third connecting hole is arranged on the baffle shell body 142, and a plurality of protrusions 143 are arranged circumferentially on the baffle shell body 142. The gap between adjacent protrusions 143 is the above-mentioned transparent window 141. The main shell 12 has a plug-in protrusion, and the sound hole 11 is arranged on the plug-in protrusion. The plug-in protrusion is plugged into the enclosed space of the plurality of protrusions 143, so as to further stabilize the baffle shell 14, and the through hole is arranged on the baffle shell body 142.

[0053] In some embodiments, the retaining shell 14 is further provided with either a handle 9 or a magnet 10, or both a handle 9 and a magnet. Thus, a miner can use the handle 9 to pick up the underground sound and light alarm signal device while walking, and when other operations are required, the light alarm signal light can be attached to a fixed position such as a frame by the magnet 10 to proceed with other operations.

[0054] A magnet is embedded within the housing 142 to stabilize the optical warning light. The handle 9 is U-shaped, with sockets located at opposite ends of the housing 14. The handle 9 plugs into these sockets, allowing the handle 9 to rotate relative to the housing 14 for easy portability. When not in use, the handle 9 can be clipped onto the housing 14, minimizing the possibility of interference during placement. For example, to facilitate the stable locking of the handle 9, the housing 14 is further provided with a clip 144. The clip 144 is positioned on a protrusion 143 between the two end points of the handle 9, securing the handle 9 to the clip 144.

[0055] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
