[0037] Please see Figure 1 and Figure 2This is one embodiment of the present invention, which provides an outdoor emergency flashlight, comprising:

[0038] The main housing 10 has a mounting cavity 11 formed inside it. A front light outlet 111 is formed at one end of the mounting cavity 11, and a lens module 12 is provided at the front light outlet 111.

[0039] The headlight module 20 has a headlight mounted inside the mounting cavity 11 and is used to emit forward beams toward the lens module 12. Existing technologies using reflectors to increase illumination density are ineffective due to their low light-gathering efficiency. This invention, however, uses the lens module 12 to guide the forward beams emitted by the headlight module 20, eliminating the need for a reflector. The lens module 12 offers superior light-gathering efficiency, helps prevent light scattering outside the beam, and results in a longer illumination distance.

[0040] A soft light module 30 is disposed within the mounting cavity 11. At least two sides of the main housing 10 are provided with soft light covers 13. The soft light module 30 emits soft light towards the soft light covers 13. After passing through the soft light covers 13, the soft light is emitted towards different sides of the main housing 10, thereby providing illumination over a wide area. By adding the soft light function, the flashlight can be used in more scenarios. In this embodiment, soft light covers 13 are provided on three sides of the main housing 10. The soft light covers 13 can be made of materials such as diffusers to facilitate uniform emission.

[0041] Please see Figure 3 and Figure 4 The specific structure of the lens module 12 can be designed according to actual needs. For example, in some optional embodiments, the lens module 12 includes a lamp head cover 121, a plane lens 122, a Fresnel lens 123, and a lens positioning plate 124. The lamp head cover 121 is disposed on the main housing 10, and a light-transmitting hole 1211 is formed on the lamp head cover 121. The lens positioning plate 124 and the plane lens 122 are arranged sequentially in the light-transmitting hole 1211 along the direction away from the front light-emitting port 111. The lens positioning plate 124 is provided with a mounting groove 1241. The Fresnel lens 123 is disposed in the mounting groove 1241 and corresponds to the position of the front light-emitting port 111. The headlight light emitted by the headlight module 20 enters the light-transmitting hole 1211 through the front light-emitting port 111, and then passes through the Fresnel lens 123 and the plane lens 122 in sequence before being emitted. Compared with the reflector, the Fresnel lens 123 can better guide the propagating light, resulting in a brighter light spot formed by the emitted light. In this embodiment, the lamp head cover 121 presses the plane lens 122 against the lens positioning plate 124, while the lens positioning plate 124 presses the Fresnel lens 123 against the main housing 10. The lamp head cover 121 is locked onto the main housing 10 by screws.

[0042] Please see Figure 5 In some optional embodiments, the mounting cavity 11 has a mounting port 112 and a front light output port 111 at its two ends, respectively, and a battery cover 114 is provided at the mounting port 112. The outdoor emergency flashlight also includes a battery module 40, a first seal 51 and a second seal 52. The battery module 40 is disposed in the mounting cavity 11 and is electrically connected to the headlight module 20 and the soft light module 30. The first seal 51 is arranged around the front light output port 111, and the lens module 12 presses the first seal 51 against the main housing 10. The second seal 52 is arranged around the mounting port 112, and the battery cover 114 presses the second seal 52 against the main housing 10. The first seal 51 prevents liquid from entering the mounting cavity 11 through the gap between the main housing 10 and the lens module 12, while the second seal 52 prevents liquid from entering the mounting cavity 11 through the gap between the main housing 10 and the battery cover 114, effectively improving the sealing performance.

[0043] In some optional embodiments, the first sealing element 51 includes a first waterproof ring 511 and a second waterproof ring 512. The first waterproof ring 511 is arranged around the front light-emitting port 111. The lamp head cover 121 is installed at the end of the main housing 10 and presses the first waterproof ring 511 against the front light-emitting port 111. The second waterproof ring 512 is disposed in the light-transmitting hole 1211 and is arranged around the lens positioning plate 124. The lamp head cover 121 presses the second waterproof ring 512 against the main housing 10 through the plane lens 122. The first waterproof ring 511 can prevent liquid from passing through the gap between the main housing 10 and the lamp head cover 121 and then entering the mounting cavity 11 through the front light-emitting port 111. The second waterproof ring 512 can prevent liquid from passing through the gap between the lens mounting plate and the inner wall of the light-transmitting hole 1211 and then entering the mounting cavity 11 through the front light-emitting port 111, thereby effectively preventing liquid from entering the mounting cavity 111 from the front light-emitting port 111 and greatly enhancing the waterproof sealing effect.

[0044] The second seal 52 may also be a third waterproof ring, which is arranged on the inner wall of the mounting port 112 and surrounds the battery cover 114, with the battery cover 114 pressing the third waterproof ring against the inner wall of the mounting port 112.

[0045] In some embodiments, the outdoor emergency flashlight also includes an operation panel module 60, which is disposed on the side of the main housing 10 and is signal-connected to the headlight module 20 for operating the headlight module 20.

[0046] Please see Figure 6Current flashlights typically rely on passive heat dissipation, transferring heat naturally to the surface of the casing, resulting in poor heat dissipation. In some alternative implementations, outdoor emergency flashlights also include a radiator 70, with a cooling fan 71 on one side. Heat dissipation holes 14 are located on opposite sides of the mounting cavity 11. The radiator 70 is positioned within the mounting cavity 11, between the heat dissipation holes 14 on both sides. The cooling fan 71 is located on the side of the radiator 70 facing the heat dissipation holes 14. The headlight module 20 and battery module 40 are respectively arranged on opposite sides of the radiator 70. Heat generated by the battery module 40, headlight module 20, and other components can be transferred to the radiator 70. The cooling fan 71 actively dissipates heat from the radiator 70, thereby improving the heat dissipation effect. The radiator 70 can employ a highly efficient heat dissipation structure such as heat dissipation fins.

[0047] The waterproof sealing structure also includes two third seals 53, which are arranged around the radiator 70. The two third seals 53 are located at both ends of the radiator 70. The radiator 70 presses the third seals 53 against the inner wall of the mounting cavity 11. The heat dissipation hole 14 is located between the two third seals 53. The third seals 53 prevent liquid from entering the mounting cavity 11 through the heat dissipation hole 14 and then entering other parts of the mounting cavity 11 through the gap between the radiator 70 and the mounting cavity 11, thereby improving the waterproof effect while achieving heat dissipation.

[0048] The specific materials used for the waterproof rings can be designed according to actual needs. For example, waterproof rings can be made of rubber or silicone.

[0049] In some optional embodiments, a charging interface 15 is provided on the outside of the main housing 10. The charging interface 15 is electrically connected to the battery module 40. Users can charge the battery module 40 through the charging interface 15, or connect electronic devices that need to be charged to the battery module 40 through the charging interface 15, and then the battery module 40 charges the electronic devices to realize the power bank function.

[0050] In some optional embodiments, a laser indicator light 113 is provided inside the mounting cavity 11. The laser indicator light 113 faces the forward-emitting light port 111 and can emit a laser beam. The laser beam passes through the forward-emitting light port 111 and exits to the outside of the main housing 10. The laser beam can be used for indication. In this embodiment, a laser through-hole 1242 is provided on the lens mounting plate. The laser beam can enter the through-hole 1211 from the forward-emitting light port 111, and then pass through the laser through-hole 1242 and the plane lens 122 in sequence, and finally exit to the outside of the main housing 10. In this way, the protective function of the plane lens 122 can be utilized, and the laser beam will not hit the Fresnel lens 123.

[0051] In some alternative embodiments, the battery cover 114 or the main housing 10 is provided with a plurality of window-breaking beads 16. The user can swing the main housing 10 to make the window-breaking beads 16 strike the glass window, thereby achieving the window-breaking function. In this embodiment, window-breaking beads 16 are provided on one or more corners of the battery cover 114.

[0052] In some optional embodiments, a display module 17 is provided on the outer side of the main housing 10. The display module 17 is signal-connected to the headlight module 20. The display module 17 can be used to display various information, such as the brightness of the headlight module 20 and the soft light module 30, the power of the battery module 40, the current time, etc., which can be designed according to actual needs. In this embodiment, a control circuit board module 80 is provided in the mounting cavity 11. The control circuit board module 80 is electrically connected to the display module 17, the headlight module 20, the soft light module 30, the operation panel module 60, the battery module 40, the cooling fan 71, and the laser indicator 113, respectively. The operation of each module is controlled by the control circuit board module 80.

[0053] In addition, in this embodiment, the heat-generating modules such as the control circuit board module 80, headlight module 20, soft light module 30, and display module 17 are directly or indirectly connected to the heat sink 70, thereby effectively transferring heat to the heat sink 70 and improving the heat dissipation effect.

[0054] In some alternative embodiments, a magnet 1141 is provided on the main housing 10 or the battery cover 114. The magnet 1141 facilitates the attachment of the main housing 10 or the battery cover 114 to a location that can be attracted by the magnet, such as a vehicle body or a ferrous metal wall, thereby easily fixing the entire flashlight without requiring the user to hold it, thus improving practicality. In this embodiment, the magnet 1141 is mounted on the battery cover 114, and the battery cover 114 is provided with a groove for embedding the magnet 1141. Of course, other suitable mounting locations can also be selected for the magnet 1141, and this example is not limited to this one.

[0055] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
