DETAILED DESCRIPTION

[0020] Combined with Figure 1 To Attachment Figure 4A battery lamp with a self-contained fire extinguishing function comprises a lamp body 3 and a rechargeable battery assembly 2 arranged in the lamp body 3, and also comprises an automatic fire extinguishing assembly 1 arranged in the lamp body 3, wherein the automatic fire extinguishing assembly 1 comprises a closed box body 12 for accommodating the rechargeable battery assembly 2, a plurality of temperature-sensitive fire extinguishing materials 11 closely attached to the rechargeable battery assembly 2, and a filler 13 placed between the rechargeable battery assembly 2 and the closed box body 12 for buffering. The closed box body 12 is divided into an upper cover 121 and a lower cover 122, wherein the upper cover 121 is composed of a square box with an opening at one end and two fixing plates arranged opposite to each other at the opening end; the lower cover 122 is a rectangular flat plate. The closed box body 12 is firmly installed inside the lamp body 3 by bolts or other fastening methods. The temperature-sensitive fire extinguishing material 11 is located inside the closed box body 12 and closely attached to the rechargeable battery assembly 2. The filler 13 is placed between the upper surface 23, the lower surface 24 or the side surface 25 of the rechargeable battery assembly 2 and the closed box body 12 to prevent the rechargeable battery assembly 2 from shaking significantly inside the closed box body 12. The beneficial effect of this embodiment is that when the rechargeable battery 21 spontaneously ignites, the closed box body 12 controls the fire in a sealed space to prevent burning of other components in the lamp body 3; and the high temperature caused by the spontaneous combustion will trigger the temperature-sensitive fire extinguishing material 11, and the closed space ensures that the flame retardant released by the fire extinguishing material 11 is at a certain concentration.

[0021] As a new implementation method, combined with the Figure 1 , the fire extinguishing material 11 is pasted on the surface (23, 24, 25) of the rechargeable battery assembly 2. The fire extinguishing material 11 is rectangular, and the fire extinguishing material 11 completely covers and is pasted on the upper surface 23 or the lower surface 24 or the four side surfaces 25 of the rechargeable battery assembly 2. It is understandable that the fire extinguishing material 11 can also be other shapes. The beneficial effect of this embodiment is that the fire extinguishing material 11 and the rechargeable battery assembly 2 are more closely fitted. This non-external force fixing method prevents the fire extinguishing material 11 from being displaced or not fitting with the rechargeable battery assembly 2, and is more convenient to use. In addition, the fire extinguishing material 11 can completely cover the surface (23, 24, 25) of the rechargeable battery assembly, and when the rechargeable battery 21 spontaneously ignites, the fire extinguishing material 11 can be triggered more quickly.

[0022] Based on the above content, in this embodiment, the fire extinguishing material 11 is a nano-microcapsule sheet encapsulating a fire extinguishing agent. Figure 1When the nano-microcapsule sheet reaches a specific temperature, its structure will rupture and release the fire extinguishing agent inside. Specifically, the fire extinguishing material 11 in this embodiment is an encapsulated nano-microcapsule sheet of perfluorohexanone. It can be understood that the fire extinguishing material 11 can also be other substances. The beneficial effect of this embodiment is that under sealed conditions, when the rechargeable battery 21 spontaneously ignites and the fire spreads to the nano-microcapsule sheet or the internal temperature reaches 180°C, the internal structure of the nano-microcapsule sheet ruptures and releases the fire extinguishing agent. Since the fire extinguishing agent perfluorohexanone has good heat absorption, it can quickly reduce the temperature of the ignition point and control the fire by lowering the temperature; if the rechargeable battery 21 reignites, the nano-microcapsule sheet can also be used repeatedly until the fire extinguishing agent in the nano-microcapsule sheet is completely released.

[0023] Based on the above, in this embodiment, the number of fire extinguishing materials 11 is 1 to 6. The number of fire extinguishing materials 11 is related to the number of rechargeable batteries 21. The more rechargeable batteries 21 there are, the more heat they will generate from spontaneous combustion. A considerable amount of fire extinguishing materials 11 is required to control the fire of spontaneous combustion. Figure 2 As shown, when the number of fire extinguishing materials 11 is 1, the fire extinguishing material 11 is attached to the lower surface of the rechargeable battery, and the filler 13 is placed between the other five surfaces of the rechargeable battery 21 and the closed box body 12; Figure 1 As shown, when the number of fire extinguishing materials 11 is 6, the fire extinguishing materials 11 are respectively attached to the upper surface 23, the lower surface 24 and the four side surfaces 25 of the rechargeable battery 21. It can be understood that when the number of fire extinguishing materials 11 is 2, the number of fillers 13 is 4, and so on, that is, the number of fire extinguishing materials 11 is 1 to 6, and the sum of the number of fire extinguishing materials 11 and fillers 13 is equal to 6. The beneficial effect of this embodiment is that, specifically, for example, when the number of rechargeable batteries 21 is four, one fire extinguishing material 11 is sufficient to effectively realize the automatic fire extinguishing function; for another example, when the number of rechargeable batteries 21 is twenty, six fire extinguishing materials 11 are required to effectively realize the automatic fire extinguishing function. The more rechargeable batteries 21 there are, the more heat they generate by spontaneous combustion, so a higher concentration of fire extinguishing agent is required to absorb the heat generated by spontaneous combustion to ensure the effective realization of the automatic fire extinguishing function. The number of fire extinguishing materials 11 is closely related to the number of rechargeable batteries 21.

[0024] Based on the above, in this embodiment, the rechargeable battery assembly 2 includes a rechargeable battery 21 and an output power line 22, and one side of the closed box body 12 is provided with an opening 123 for the output power line 22 to pass through. Figure 1, the opening 123 is a rectangular through hole with a single-sided opening. In order to make the subsequent sealing more tight, the size of the opening 123 is designed to be slightly larger than the output power line 22. The rechargeable battery 21 is located in the closed box body 12, and the output power line 22 passes through the opening 123 on the side of the closed box body 12 and is connected to the wire located outside the closed box body 12. The beneficial effect of this embodiment is that the size of the opening 123 provides convenience for the subsequent sealing work, and the output power line 22 can also pass through the opening 123 to supply power to other components in the lamp body 3.

[0025] Based on the above content, in this embodiment, a battery lamp with a self-extinguishing function further includes an isolating member 14 elastically embedded in the opening 123, and the output power line 22 passes through the isolating member 14 and the two are closely attached to each other. Figure 1 The isolator 14 is a rectangle with a through hole 141 in the center, and its size is consistent with the size of the opening 123 on the side of the closed box body 12, and the isolator 14 is a stretchable elastic element. The inner surface of the central through hole 141 of the isolator 14 and the output power line 22 are closely fitted to each other. The beneficial effect of this embodiment is that the design of the isolator 14 is to effectively prevent the flame from spreading through the opening 123 to other components inside the lamp body 3 when the rechargeable battery 21 spontaneously ignites, and the fire extinguishing agent released by the fire extinguishing material 11 from leaking through the opening 123.

[0026] Based on the above content, in this embodiment, the spacer 14 is preheated expansion cotton. It can be understood that the spacer 14 can also be made of other materials. Figure 1 , the isolation member 14 seals the opening 123 of the closed box body 12. When the rechargeable battery 21 spontaneously ignites and causes the temperature to rise, the preheating expansion cotton expands in volume, making its contact with the opening 123 and the output power line 22 more tightly, ensuring that the seal at the opening 123 is airtight. The beneficial effect of this embodiment is that it can not only prevent the fire in the closed box body 12 from spreading to other components in the lamp body, but also prevent the fire extinguishing agent in the closed box body 12 from leaking. Air is prevented from entering the closed box body 12 through the opening 123, thereby limiting the oxygen supply required for the fire.

[0027] As a new implementation, the filler 13 is EVA padding. Figure 2 The EVA pad is rectangular and is placed between the upper surface 24 and four side surfaces 25 of the rechargeable battery assembly 2 and the closed box body 12 to reduce the collision between the rechargeable battery assembly 2 and the closed box body 12 and play a role of buffer protection. The beneficial effect of this embodiment is that the rechargeable battery assembly 2 is prevented from shaking in the closed box body 12.

[0028] In summary, the working principle of a battery lamp with a self-extinguishing function is as follows: when the rechargeable battery 21 spontaneously ignites due to short circuit, aging or working in a high temperature environment, the fire extinguishing material 11 nanometer microcapsule sheet pasted around the fire point absorbs enough heat, and its internal structure begins to break and releases the fire extinguishing agent perfluorohexanone; and when the temperature in the closed box reaches 180°C, the fire extinguishing material 11 nanometer microcapsule sheet away from the fire point absorbs enough heat, thereby destroying its internal structure and releasing the perfluorohexanone fire extinguishing agent encapsulated inside the fire extinguishing material 11 nanometer capsule sheet. Perfluorohexanone can quickly control and extinguish the fire caused by the spontaneous combustion of the rechargeable battery 21 through its strong heat absorption capacity and excellent electrical insulation performance. At the same time, in order to prevent the fire from spreading to the outside of the closed box body 12, a preheating expansion cotton of an isolating member 14 with a sealed opening 123 is provided. The preheating expansion cotton of the isolating member 14 expands in volume when the temperature in the closed box body 12 rises, and the fire is confined to the inside of the closed box body 12, ensuring that the fire is within a controllable safety range.

[0029] The utility model provides a battery lamp with a built-in fire extinguishing function. There are two forms of lamp body structure, each of which can be applied to any of the above-mentioned implementation methods.

[0030] One of them, combined with Figure 3 The lamp body 3 includes a front cover assembly 31 and a rear cover assembly 32, and the automatic fire extinguishing assembly 1 is located between the front cover assembly 31 and the rear cover assembly 32. The beneficial effect of this embodiment is that the battery lamp also includes a lamp board heat dissipation assembly 4, the lamp board heat dissipation assembly 4 is located between the front cover assembly 31 and the rear cover assembly 32, and the automatic fire extinguishing assembly 1 is installed below the lamp board heat dissipation assembly 4. The assembly installation of this lamp body structure is relatively compact, so the battery lamp of this lamp body structure is small in size and more convenient to carry.

[0031] Another method, combined with Figure 4 The lamp body 3 includes a lamp head assembly 6 and a bottom box assembly 5, and the automatic fire extinguishing assembly 1 is located in the bottom box assembly 5. The beneficial effect of this embodiment is that the lamp head assembly 6 rotates around the X-axis and is installed above the bottom box assembly 5. This design makes the battery lamp irradiate a wider range. The bottom box assembly 5 is a rectangular box with an open end, and the lamp body 3 also includes a bracket assembly 7. The automatic fire extinguishing assembly 1 is installed in the bottom box assembly 5, and is located between the bottom box assembly 5 and the bracket assembly 7. The automatic fire extinguishing device 1 of this lamp body structure is far away from the lamp head assembly 6 containing the light source, and when the rechargeable battery 21 spontaneously ignites, it will not affect the lamp head assembly 6.
