The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0037] The present invention provides a flashlight 10 suitable for outdoor lighting, such as Figure 1 and Figure 2 As shown, it includes: a barrel 100, a light-emitting component 200, a power supply component 300 and a lamp holder component 400, the lamp holder component 400 is installed on the barrel 100, the light-emitting component 200 is arranged in the barrel 100, and the light-emitting component 200 is located between the barrel 100 and the lamp holder component 400.

[0038] Among them, Figure 3 As shown, the light emitting component 200 includes an LED lamp bead 210 and a heat dissipation auxiliary component 220 that contacts and cooperates with the LED lamp bead 210 .

[0039] like Figure 2 and Figure 3As shown, the lamp head component 400 includes: an outer cover body 410, a reflective cup 420 and a protective component 430. The outer cover body 410 is threadedly connected to the barrel 100. The reflective cup 420 and the protective component 430 are arranged in the outer cover body 410. The LED lamp bead 210 is located on one side of the reflective cup 420, and the protective component 430 is located on the other side of the reflective cup 420. The main function of the protective component 430 is to make the flashlight 10 have a better dustproof and waterproof effect, and at the same time enhance the drop resistance of the flashlight 10.

[0040] In this embodiment, if Figure 2 and Figure 3 As shown, the protective component 430 includes: a light-transmitting member 431, a first sealing ring 432, a second sealing ring 433 and a front protective member 434. The light-transmitting member 431 is located on one side of the reflective cup 420, the first sealing ring 432 is arranged between the light-transmitting member 431 and the outer cover body 410, the second sealing ring 433 is arranged between the light-transmitting member 431 and the reflective cup 420, and the front protective member 434 is arranged at the end of the outer cover body 410, and the front protective member 434 is pressed on the light-transmitting member 431.

[0041] Compared with the prior art, the protective component 430 of the present invention has a first sealing ring 432 and a second sealing ring 433. The first sealing ring 432 is arranged between the light-transmitting member 431 and the outer cover body 410, that is, the first sealing ring 432 is sleeved on the outer circumferential side wall of the light-transmitting member 431, so that the gap between the light-transmitting member 431 and the outer cover body 410 is filled by the first sealing ring 432. At the same time, the second sealing ring 433 is arranged between the light-transmitting member 431 and the reflective cup 420, and the second sealing ring 433 also abuts against the inner wall of the outer cover body 410. In this way, the cooperation between the first sealing ring 432 and the second sealing ring 433 enables the protective component 430 to have the following benefits:

[0042] First, the double sealing ring arrangement better fills the gap between the parts, thereby better preventing dust and water vapor from entering the flashlight 10;

[0043] Secondly, the setting of the double sealing ring allows a larger tolerance of the light-transmitting member 431, thereby reducing the processing accuracy requirements of the light-transmitting member 431;

[0044] Thirdly, the first sealing ring 432 is sleeved on the outer circular side wall of the light-transmitting member 431. In this way, when the flashlight 10 is bumped, the first sealing ring 432 can provide a buffer for the light-transmitting member 431, thereby protecting the fragile light-transmitting member 431. Similarly, the second sealing ring 433 is arranged between the light-transmitting member 431 and the reflective cup 420. When the flashlight 10 is bumped, the second sealing ring 433 provides a buffer for the light-transmitting member 431 and the reflective cup 420, thereby playing a protective role.

[0045] In this embodiment, if Figure 3 As shown, the front protective member 434 is threadedly matched with the outer cover body 410 . The front protective member 434 is provided with a wave structure 434 a and a rolled edge 434 b . The rolled edge 434 b is pressed against the edge of the outer cover body 410 .

[0046] When the front protective member 434 is impacted by a collision, the front protective member 434 will transfer most of the impact force to the outer cover body 410 through the rolled edge 434b and the threaded structure, thereby protecting the relatively fragile parts in the outer cover body 410 from the impact. Only a very small amount of the impact force will be transmitted to the light-transmitting member 431, and due to the buffering effect of the second sealing ring 433, the light-transmitting member 431 will not be affected by the impact force. Therefore, when necessary, the flashlight 10 can be used as a life-saving hammer; moreover, the front protective member 434 is provided with a wave structure 434a, so that the flashlight 10 can more easily break through obstacles when hammering.

[0047] Further, in another embodiment, if Figure 4 and Figure 5 As shown, a detachable lamp holder 230 is provided between the barrel 100 and the light-emitting component 200, and the lamp holder 230 is used to connect the barrel 100 and the light-emitting component 200. The heat dissipation auxiliary component 220 is an aluminum substrate structure; the LED lamp bead 210 is attached to the lamp holder 230 through the heat dissipation auxiliary component 220. The power supply component 300 includes a control board 310 (such as Figure 7 As shown), the control board 310 and the LED lamp bead 210 are electrically connected through the wire 311, and the wire 311 is passed through the lamp holder 230 (the wire 311 includes a positive wire and a negative wire).

[0048] Compared with the prior art, the flashlight 10 of this embodiment is additionally provided with a heat dissipation auxiliary component 220, and the heat dissipation auxiliary component 220 is an aluminum substrate structure. When in use, the LED lamp bead 210 generates light and heat, and the heat is transferred to the heat dissipation auxiliary component 220, thereby increasing the heat dissipation area; the heat dissipation auxiliary component 220 will further transfer the heat to the lamp holder 230 and the barrel 100, thereby further accelerating the heat dissipation, so that the flashlight 10 has a good heat dissipation effect and prolongs the service life of the flashlight 10. In addition, the aluminum substrate structure can reduce the production cost while taking into account the thermal conductivity.

[0049] Compared with the prior art, the flashlight 10 of this embodiment is further provided with a detachable lamp holder 230. The conventional lamp holder 230 is usually formed integrally with the barrel 100, and the workpiece is subjected to surface oxidation treatment after production, so that the barrel portion of the workpiece is more durable. However, after the surface treatment, there will be a layer of oxide film on the lamp holder portion of the workpiece, which makes the contact heat dissipation efficiency of the LED lamp bead 210 low (the thermal conductivity is not high), and is therefore not conducive to the heat dissipation of the LED lamp bead 210. The lamp holder 230 of the present invention is set to be detachable, so that during production and processing, the barrel 100 and the lamp holder 230 can be processed at the same time, thereby shortening the processing time and facilitating the installation of the light-emitting component 200 on the lamp holder 230; at the same time, the barrel 100 can be surface treated separately, while the lamp holder 230 is not surface treated, so that both the durability of the barrel 100 and the good contact heat dissipation efficiency of the lamp holder 230 can be taken into account.

[0050] It should be emphasized that in the present embodiment, the lamp holder 230 and the barrel 100 are connected by threads, so that the lamp holder 230 and the barrel 100 can be stably connected, and the contact area between the lamp holder 230 and the barrel 100 can be increased, thereby enhancing the thermal conductivity between the lamp holder 230 and the barrel 100, so that the heat of the lamp holder 230 can be dissipated faster through the barrel 100.

[0051] However, when the lamp holder 230 is threaded, the following new technical problems will arise: the control board 310 is installed in the barrel 100 before the lamp holder 230, and Figure 6 As shown, the wire 311 (positive wire and negative wire) needs to pass through the lamp holder 230 to achieve electrical connection between the control board 310 and the LED lamp bead 210. After the wire 311 passes through the lamp holder 230, the lamp holder 230 is spirally connected to the cylinder 100, which causes the wire 311 to rotate with the lamp holder 230, so that the positive wire and the negative wire are easily entangled. To this end, the present invention further improves the structure of the lamp holder 230 to overcome the problem of the wire 311 being entangled.

[0052] Specifically, Figure 7 As shown, the lamp holder 230 is provided with a waist-shaped avoidance slot 231, and the wire 311 is passed through the waist-shaped avoidance slot 231 (the wire 311 includes a positive wire and a negative wire). During installation, the staff first gathers the positive wire and the negative wire together in the middle of the waist-shaped avoidance slot 231, and then spirally connects the lamp holder 230 with the cylinder 100. In this way, during the spiral process, the wire 311 will not rotate with the lamp holder 230, and the positive wire and the negative wire will not be entangled together. After the lamp holder 230 is tightened, the staff will arrange the positive and negative wires to the two sides of the waist-shaped avoidance slot 231, and finally electrically connect the positive and negative wires to the LED lamp beads 210 respectively.

[0053] It should be noted that after such a design, the heat dissipation auxiliary member 220 still maintains contact with the inner wall of the lamp holder 230, and the heat of the heat dissipation auxiliary member 220 can still be transferred to the lamp holder 230 through the contact surface, which will not have a substantial impact on the heat dissipation of the light-emitting component 200. At the same time, it is convenient for the wire 311 to pass through the lamp holder 230, and avoids the entanglement of the wire 311 caused by the spiral of the lamp holder 230.

[0054] Furthermore, the flashlight 10 of the present invention also has a power display function, and the user can always observe the power status of the built-in battery of the flashlight 10.

[0055] Specifically, Figure 7 As shown, the control panel 310 is provided with a plurality of power indicator lights 312 and a switch button 313. The power supply component 300 includes a built-in battery 320 and a key display assembly 330. The built-in battery 320 supplies power to the control panel 310 and the LED lamp beads 210.

[0056] Among them, Figure 8 and Fig. 9 As shown, the key display assembly 330 includes: a split light key frame 331, a key rod 332 and a key conduit cap 333. The split light key frame 331 is mounted on the control board 310, and a light channel 331a is provided on the split light key frame 331 to cooperate with the power indicator light 312; the key rod 332 is supported on the switch button 313, and the key rod 332 is slidably disposed on the split light key frame 331; the key conduit cap 333 is located between the split light key frame 331 and the cylinder 100.

[0057] Preferably, Fig. 9 , Fig.10 and Fig.11 As shown, there are multiple power indicator lights 312, the number of light channels 331a is the same as the number of power indicator lights 312, and each light channel 331a corresponds to a power indicator light 312. A light guide column 333a is provided on the key conduit cap 333, the number of the light guide column 333a is the same as the number of the power indicator lights 312, and the light guide column 333a is penetrated through the cylinder 100.

[0058] When working, the control panel 310 monitors the remaining power of the built-in battery 320 and displays it through the power indicator light 312 (for example, 0-25% is displayed by 1 light, 25%-50% is displayed by 2 lights, 50%-75% is displayed by 3 lights, and 75%-100% is displayed by 4 lights). The light emitted by each power indicator light 312 passes through the light channel 331a of the corresponding split light key frame 331 and irradiates the corresponding light guide column 333a (such as Fig.10As shown), the light is refracted multiple times in the light guide column 333a, so that the corresponding light guide column 333a is illuminated, and the user can judge the remaining power of the built-in battery 320 by observing the number of luminous light guide columns 333a.

[0059] It should be noted that the key conduit cap 333 is designed mainly to prevent dust and water. Since the flashlight 10 is to be used outdoors, the barrel 100 needs to be well sealed at the key portion. By providing the key conduit cap 333, the edge of the key conduit cap 333 is abutted against the inner wall of the barrel 100 (such as Fig.10 As shown), this can prevent external dust or water vapor from entering the barrel 100.

[0060] The design of the spectroscopic key frame 331 has two functions: on the one hand, the spectroscopic key frame 331 provides support for the key guide cap 333 and also limits the sliding of the key rod 332, so that the key rod 332 can be accurately pressed onto the switch button 313; on the other hand, the light channel 331a of the spectroscopic key frame 331 separates the light emitted by each power indicator light 312, thereby preventing the power indicator light 312 from irradiating the non-corresponding light guide column 333a.

[0061] In one embodiment, if Fig. 9 and Fig.10 As shown, a charging interface 340 is provided on the control board 310, and a detachable safety helmet 110 is provided on the barrel 100, and the safety helmet 110 is covered at the charging interface 340. The charging interface 340 is electrically connected to the control board 310, and the setting of the safety helmet 110 makes the charging interface 340 also dustproof and waterproof.

[0062] In summary, the flashlight 10 suitable for outdoor lighting of the present invention has good sealing and drop resistance, and also has a good heat dissipation structure, which can meet the needs of outdoor adventure sports.

[0063] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
