Abstract
Description
Technical Field
[0001] This application relates to the field of lighting, and more particularly to an emergency flashlight. Background Technology
[0002] A flashlight is a handheld electronic lighting tool.
[0003] The flashlight includes a handle-type housing for handheld use and a lamp head mounted at the end of the housing. The housing has a tail cap on the side away from the lamp head to encapsulate the battery in the inner cavity of the housing.
[0004] Conventional handheld flashlights only emit light from the head. When in use, the illuminated area is in front of the pedestrian, while the area behind remains dark. When many people are walking at night, in order to make the pedestrians see the road conditions as much as possible, the person holding the flashlight needs to be at the back of the crowd to provide lighting. The area in front of the flashlight where the pedestrians' shadows are still in darkness, resulting in poor road lighting and no good lighting environment.
[0005] Therefore, how to design a flashlight that can provide a good lighting environment has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0006] This application provides an emergency flashlight to at least solve the above-mentioned technical problems existing in the prior art.

[0043] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0044] like Figure 1 As shown, it includes a handheld housing 1, a lamp head 2 and a tail end cap 3 respectively installed at both ends of the housing 1, wherein the tail end cap 3 is threadedly connected to the housing 1 to seal the inner cavity of the housing 1.
[0045] It is worth noting that the tail cap 3 is separate from the outer casing 1.
[0046] like Figure 2 As shown, a battery 4 and a control panel 5 are installed in the inner cavity of the outer shell 1. A first light source 21 is provided in the lamp head 2. The first light source 21 is connected to the control panel 5 through a first touch switch 61. The battery 4 powers the flashlight. When the first touch switch 61 is pressed, the circuit of the first light source 21 is turned on, and the first light source 21 is lit, thereby enabling illumination in front of the flashlight.
[0047] In order to solve the lighting problem at the tail of the flashlight, in this embodiment, as follows: Figure 2 and Figure 3 As shown, the tail end cap 3 is provided with a second light source 31. The flashlight also includes a control circuit 7 and a second touch switch 62. The second touch switch 62 is electrically connected to the control panel 5. The control panel 5 is connected to the second light source 31 by the control circuit 7. The second touch switch 62 controls the second light source 31 to be powered on / off.
[0048] It is worth noting that the first touch switch 61 controls only the first light source 21, while the second touch switch 62 controls the second light source 31. The first light source 21 and the second light source 31 can be lit simultaneously to provide a better lighting environment.
[0049] Since the tail cap 3 and the outer shell 1 are separate, in order to control the second light source 31, in this embodiment, as follows: Figure 3 and Figure 5As shown, the control circuit 7 includes a first control section 71 and a second control section 72. The first control section 71 is mounted on the housing 1, and the second control section 72 is mounted on the tail end cover 3. When the tail end cover 3 is separated from the housing 1, the first control section 71 and the second control section 72 are separated. When the tail end cover 3 is mounted on the housing 1, the first control section 71 and the second control section 72 are connected.
[0050] Specifically, such as Figure 5 As shown, the first control section 71 includes a first wire 711 and a first contact 712. The first wire 711 is electrically connected to the first contact 712, and the first wire 711 is also electrically connected to the control panel 5.
[0051] In order to achieve the installation of the first control segment 71, in this embodiment, as follows: Figure 5 As shown, the outer casing 1 is provided with a first embedding channel 10, and the peripheral wall of the outer casing 1 is provided with an embedding groove 101 that is recessed inward. It is worth noting that the inner side here refers to the side close to the axis of the outer casing 1. The first wire 711 is buried in the first embedding channel 10, and the first contact 712 is set in the embedding groove 101. After the first contact 712 is installed, the first contact 712 is lower than the peripheral wall of the outer casing 1.
[0052] To achieve the installation of the second control segment 72, in this embodiment, as follows: Figure 5 and Figure 6 As shown, the second control section 72 includes a second wire 721 and a second contact 722 connected to the second wire 721. The second wire 721 is connected to the second light source 31. The tail end cap 3 is provided with a second embedding channel 33 and also includes an embedding hole 34 that connects the second embedding channel 33 to the threaded part on the tail end cap 3. The second wire 721 is disposed in the second embedding channel 33 and the second contact 722 is disposed in the embedding hole 34. Specifically, the second contact 722 is an elastic contact. When the tail end cap 3 is connected to the housing 1, the second contact 722 retracts into the embedding hole 34 to avoid interfering with the connection between the internal thread on the housing 1 and the external thread on the tail end cap 3. When the tail end cap 3 is installed on the housing 1 or when the tail end cap 3 is separated from the housing 1, the second contact 722 extends out of the embedding hole 34.
[0053] After the tail end cap 3 and the outer casing 1 are installed, the second contact 722 is connected to the first contact 712, as follows. Figure 5 As shown, the second light source 31 can be powered on via the second touch switch 62 and the control circuit 7.
[0054] To achieve the installation of the second light source 31, in this embodiment, as follows: Figure 4 As shown, the tail end cap 3 has a mounting groove 30, in which the second light source 31 is disposed within the mounting groove 30 and is also enclosed by a cover 32, as shown. Figure 7As shown, the peripheral wall of the encapsulation cover 32 is provided with a connecting part 321. The connecting part 321 of the encapsulation cover 32 is threadedly connected to the inner wall of the mounting groove 30, thereby encapsulating the second light source 31 in the mounting groove 30.
[0055] The encapsulation cover 32 is also provided with a pressing part 322. When the encapsulation cover 32 is threadedly connected to the mounting groove 30, the pressing part 322 abuts against the second light source 31, thereby fixing the second light source 31.
[0056] It is worth noting here that, as Figure 7 As shown, the encapsulation cover 32 is also provided with a lens 323. At this time, the light emitted by the second light source 31 can pass through the lens 323 and be emitted outward, realizing illumination behind the flashlight and providing a good lighting environment.
