[0025] The following specific implementation manner will further illustrate the present utility model in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0026] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. 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 of the related listed items.

[0029] See also Figures 1 to 4, shown is a flashlight in the first embodiment of the utility model, including a flashlight body 10, a flashlight lamp head 20 arranged at one end of the flashlight body 10, a lighting component 30 arranged in the flashlight lamp head 20, a distance measuring component 40, and a display component 50 arranged on the flashlight body 10 or the flashlight lamp head 20, the display component 50 is communicatively connected with the distance measuring component 40, the axis of the lighting component 30 coincides with the axis of the flashlight lamp head 20, the axis of the distance measuring component 40 is parallel to the axis of the lighting component 30 and maintains a preset distance, and a switch component 60 is also provided on the flashlight body 10 for controlling the lighting component 30, the distance measuring component 40 and the display component 50 respectively.

[0030] It can be understood that the basic lighting function of the flashlight is realized by controlling the lighting component 30, and the distance measuring component 40 and the display component 50 controlled by the switch component 60 are set, so that the flashlight can also perform laser distance measurement when lighting, and display it through the display component 50, so that the user can clearly know the distance between the flashlight and himself, so that the user can effectively judge the distance between the ground gully and himself when he is active at night, and the width of the gully can be determined when he is at the edge of the gully, so as to ensure the safety of the user walking at night. Therefore, the utility model solves the technical problem that the flashlight in the prior art has a single function and the user cannot accurately judge the width of the gully and the distance between himself and the gully when walking at night.

[0031] Specifically, the lighting assembly 30 includes a control circuit board 31, a light source 32 disposed on the control circuit board 31, a reflective cup 33 and a convex lens 34. A mounting groove 21 is provided on the flashlight lamp head 20, and the reflective cup 33 is disposed in the mounting groove 21. The control circuit board 31 is disposed at the closed end of the reflective cup 33 and fixed at the bottom of the mounting groove 21. The convex lens 34 is disposed at the open end of the reflective cup 33 and fixed at the top of the mounting groove 21. The lighting function of the flashlight is controlled by arranging a wired or wireless communication connection between the control circuit board 31 and the switch assembly 60. In addition, by arranging the reflective cup 33 and the convex lens 34, the light irradiated by the light source 32 of the lighting assembly 30 is converged by the reflective cup 33, and is guided by the convex lens 34 to a specified direction for diffuse irradiation at a certain angle.

[0032] It should be noted that the light generated by the light source 32 can be white light or green light. When the user carries the flashlight for night activities, white light is usually used, and the light provided by the white light source 32 is the clearest. When the user carries the flashlight for night jungle exploration, green light is usually used. Animals are not sensitive to green light. When hunting in the wild jungle, green light can ensure the lighting effect, so that the user can find the animals, and prevent the animals from escaping due to stress caused by strong light exposure. In addition, green light has a stronger penetration effect than white light and is more conspicuous. When asking for help at night, it is more conducive to the discovery of search and rescue personnel by shooting green light into the sky. It should be noted that when the light source 21 uses green light, the distance measuring component 40 needs to be designed with anti-interference to prevent the green light source from affecting the laser distance measuring function of the distance measuring component 40.

[0033] Furthermore, the display assembly 50 includes a transparent display screen 51, and the transparent display screen 51 is located between the convex lens 34 and the reflective cup 33. By setting the display assembly 50 as the transparent display screen 51, after the distance measuring assembly 40 performs laser distance measurement, the distance measuring information is transmitted to the transparent display screen 51, and the transparent display screen 51 obtains the distance between the flashlight and the illuminated location according to the distance measuring information, and displays the distance through the transparent display screen 51. In a specific implementation, the transparent display screen 51 can display the distance measuring information in a partially red font, and the light of the light source passes through the partially red transparent display screen 51, so that there will be a red image in the light spot at the illuminated location of the flashlight, and the user can directly know the distance measuring information.

[0034] In addition, a speaker assembly 70 is also provided on the side of the flashlight body 10, and the speaker assembly 70 is in communication connection with the distance measuring assembly 40. By providing the speaker assembly 70, the information measured by the distance measuring assembly 40 can also be broadcasted through the speaker assembly 70, so that the distance measuring information can also be known when the display assembly 50 fails. In addition, the speaker assembly 70 also has a recording function, which is used to store important information when the user's mobile device is out of power.

[0035] Specifically, the switch assembly 60 includes a light switch 61 and a distance-measuring switch 62 disposed on the side of the flashlight barrel 10, and the light switch 61 and the distance-measuring switch 62 have different appearances. The light switch 61 and the distance-measuring switch 62 are respectively disposed to control the lighting assembly 30 and the distance-measuring assembly 40, so that the functions can be turned on and off as needed when distance measurement or lighting is required. In addition, the two switches have different shapes, so that at night, the user can directly know where the buttons of the two functions are based on the appearance, without having to identify the buttons by sight in the dark.

[0036] In addition, two mutually interconnected rope holes 12 are provided on the side of the flashlight body 10 away from the flashlight lamp head 20. A soft rope can be passed through the rope hole 12 so that the flashlight can be put on the hand through the rope, which is convenient for carrying the flashlight and makes the flashlight less likely to fall out of the hand. In addition, a socket 13 is provided on the end face of the flashlight body 10 away from the flashlight lamp head 20, and the flashlight can be charged through the socket 13.

[0037] By way of example and not limitation, in some optional embodiments, the display component 50 includes an LED display screen 53, which is disposed on the side of the flashlight barrel 10 to display the measurement parameters of the distance measuring component 40. Although the distance measuring information can be directly displayed at the illuminated light spot by providing a transparent display screen 51, if the illumination distance is far, the distance measuring information will be unclear. Therefore, an LED display screen 53 can also be provided so that the distance measuring information can also be obtained on the flashlight barrel.

[0038] It should be noted that the communication between the above-mentioned device components can be carried out by wireless communication methods such as WIFI, Bluetooth, infrared, radio frequency, etc. Alternatively, the transmission can be carried out by wired communication. When the wired communication method is adopted, a wiring groove can be set inside the shell, and the wires can connect the devices through the wiring groove. In addition, the power supply of the above-mentioned devices can be powered by the battery provided by the flashlight as the light source, or each can be provided with an independent power supply.

[0039] See also Figure 5 to Figure 6 , shown is a flashlight in the second embodiment of the utility model. The second embodiment is generally the same in structure as the first embodiment, except that the display component 50 includes a projection source 52, which is arranged on the control circuit board 31, and the axis of the projection source 52 is parallel to the axis of the lighting component 30 and maintains a preset distance. In addition, the transparent display screen 51 is provided to realize the function of displaying the ranging information, which is costly. Therefore, the display of the ranging information can be realized by additionally providing a projection source 52. The projection source 52 receives the measurement information of the ranging component 40, and directly projects the ranging information at the edge of the light spot to prevent the brightness of the light spot from being too high to cover the ranging information image projected by the projection source 52. Specifically, the display component 50 at this time can be a micro projector.

[0040] By way of example and not limitation, in some optional embodiments, the display assembly 50 includes a projection component 54, which is disposed on the side of the flashlight barrel 10 and is used to project and display the measurement parameters of the ranging component 40. The ranging data is directly projected onto the light spot. If the irradiation distance is too far or the irradiation area is too rugged, the projected image will be very blurry and difficult to see clearly. Therefore, the projection component 54 is disposed on the side of the flashlight barrel 10 so that the projection component 54 projects the ranging information onto the feet and directly obtains the information.

[0041] Furthermore, a fixing groove 11 is provided on the side of the flashlight barrel 10, and the display assembly 50 further includes a transmission rod 55 symmetrically arranged on both sides of the projection component 54, and the two ends of the transmission rod 55 are rotatably connected to the side walls of the fixing groove 11 and the side walls of the projection component 54 respectively. By setting the fixing groove 11, the projection component 54 is set in the fixing groove 11, and then the projection component 54 can be taken out of the fixing groove 11 when it is needed through the transmission rod 55. Since the transmission rod 55 is provided, the projection position of the projection component 54 can be manually adjusted. When the ground under the feet is uneven due to the large amount of weeds, the projection component 54 can be aimed at the relatively flat ground nearby, so that the projection effect of the projection component 54 is better, and the distance measurement information can be obtained more clearly and accurately.

[0042] Furthermore, the transmission rod 55 is rotatably connected to the side wall of the fixing groove 11 and the side wall of the projection component 54 respectively through a rotating shaft 56, and an elastic gasket 57 is provided on the rotating shaft 56. By providing the elastic gasket, there is damping when the transmission rod 55 rotates relative to the fixing groove 11 and the projection component 54, so that when the projection component 54 is rotated to adjust its projection angle and position, the rotation angle of the projection component 54 can be stably maintained after the rotation angle is adjusted, so that the projected image is stable and clear. In addition, in some optional embodiments, a recessed activity space can be further provided on the side of the flashlight barrel 10, and the projection component 54 is provided in the activity space through a movable rotating shaft and is rotatably connected to the flashlight barrel 10, and at least part of the projection part of the projection component 54 protrudes from the flashlight barrel 10, and the projection direction of the projection component 54 can be adjusted through the rotating shaft.

[0043] In summary, the flashlight in the above embodiment of the utility model realizes the basic lighting function of the flashlight by setting the switch assembly 60 to control the lighting assembly 30, and by setting the distance measuring assembly 40 and the display assembly 50 controlled by the switch assembly 60, the flashlight can also perform laser distance measurement when lighting, and display it through the display assembly 50, so that the user can clearly know the distance between the flashlight and himself, so that the user can effectively judge the distance between the gully on the ground and himself when he is active at night, and the width of the gully can be determined when he is at the edge of the gully, so as to ensure the safety of the user walking at night. Therefore, the utility model solves the technical problem that the flashlight in the prior art has a single function and the user cannot accurately judge the width of the gully and the distance between himself and the gully when walking at night.
