Description

Technical Field

[0001] This utility model relates to the field of warning device technology, and in particular to a nighttime warning device. Background Technology

[0002] Nighttime warning devices are mainly used for nighttime construction safety warnings, traffic warnings, or road construction warnings.

[0003] However, the light emitted by existing night warning devices is usually diffused, resulting in a relatively limited light propagation distance. In scenarios with poor visibility and the need for long-distance warning, the light from ordinary warning devices cannot be effectively transmitted. Therefore, this application proposes a night warning device to address this problem. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the warning distance of traditional night warning devices is relatively limited due to the diffused light, and therefore a night warning device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A nighttime warning device includes a light-emitting component, the light-emitting component including a light source and a lampshade, the lampshade including an outer lens that focuses light horizontally and an inner lens that focuses light vertically, the inner lens being located inside the outer lens, and the light source being located inside the inner lens.

[0006] Preferably, the outer lens is cylindrical, and the side of the outer lens is serrated.

[0007] Preferably, the inner lens has a triangular cross-section and is evenly arranged in a circle, and the inner lens is fixedly disposed inside the outer lens.

[0008] Preferably, the light source includes a circuit board, and lamp beads are provided on both the front and rear sides of the upper part of the circuit board, with the lamp beads located inside the inner lens.

[0009] Preferably, it also includes a power supply component, which includes a grip, the bottom of the outer lens is detachably connected to the top of the grip, and a sealing structure is provided at the connection position, and the lower part of the circuit board is detachably disposed in the upper inner part of the grip.

[0010] Preferably, the power supply assembly further includes a battery compartment disposed in the lower part of the grip, the battery compartment containing a battery, and a back cover detachably connected to the bottom of the grip, the battery supplying power to the circuit board.

[0011] Preferably, it also includes a reflective component disposed on the inner top of the outer lens, the reflective component being used to reflect light to the inner lens.

[0012] Preferably, the reflective assembly includes a reflector that snaps onto the top of the outer lens.

One end of the connecting post is fixedly connected to the reflector, and the other end is fixedly connected to the locking block. The bottom of the locking block is engaged with the top of the circuit board.

[0014] Compared with the prior art, the present invention provides a night warning device with the following beneficial effects.

[0015] 1. This utility model, through the setting of the inner lens, can vertically concentrate the light, so that the light rays are emitted in vertical planes. Then, in conjunction with the outer lens, the light rays are horizontally concentrated to form beams of light, thereby improving the concentration of light and making the range longer. This solves the problem that the warning distance of traditional night warning devices is relatively limited due to the relatively diffuse light.

[0016] 2. This utility model, through the provided reflective component, can reflect the upward diffused light from the lamp source and reflect the light to the inner lens, thereby increasing the intensity of the emitted light.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0031] Please refer to Figures 1-10 A nighttime warning device includes a light-emitting component, which includes a light source and a lampshade. The lampshade includes an outer lens 1 that focuses light horizontally and an inner lens 16 that focuses light vertically. The inner lens 16 is located inside the outer lens 1, and the light source is located inside the inner lens 16.

[0032] In a specific embodiment of this utility model, the light source is mainly used for emitting light, while the lampshade is used to protect the light source and also for transmitting and focusing light. The outer lens 1 enables the light to form parallel light after passing through it, achieving a horizontal focusing effect and avoiding the problem of short light transmission distance caused by the vertical diffusion of light. The inner lens 16 enables the light to form vertically radial light beams, achieving a vertical focusing and radial emission effect. In use, the diffused light emitted by the light source passes through the inner lens 16 and forms layers of vertical light beams. Then, after the light beams pass through the horizontal focusing of the outer lens 1, they form beams that are emitted. The beams that are focused in this way can achieve a longer range, increasing the warning distance of the warning device.

[0033] The outer lens 1 is cylindrical, and the side of the outer lens 1 is serrated. In this design, the side of the outer lens 1 is made using the Fresnel lens principle, which enables divergent light to be converted into parallel light after passing through.

[0034] The inner lens 16 has a triangular cross-section and is evenly arranged in a circle. The inner lens 16 is fixedly installed inside the outer lens 1. The inner lens 16 is a vertical focusing lens. When light passes through the inner lens 16, it is compressed into layers of vertical light. Together with the outer lens 1, the light is formed into beams. The direction of the final emitted light is the line after the intersection of the vertical and horizontal planes, which is the direction of the final beam.

[0035] The light source includes a circuit board 6, and LED beads 7 are provided on both the front and back sides of the upper part of the circuit board 6. The LED beads 7 are located inside the inner lens 16.

[0036] Specifically, LED beads can be used for the lamp 7; the circuit board 6 is mainly used to control the opening and closing of the lamp 7, and at the same time, the circuit board 6 connects the lamp 7 and the battery. The design of the circuit board 6 adopts the existing conventional design.

[0037] To further enhance the warning effect, a sound generator can be installed on the grip 2 to achieve an audio-visual warning effect. The sound generator can be a miniature ultrasonic speaker, which is fixedly installed on the grip 2 and connected to the circuit board 6 through wires, and powered by a battery to produce sound.

[0038] It also includes a power supply component, which includes a grip 2, with the bottom of the outer lens 1 detachably connected to the top of the grip 2 and a sealing structure provided at the connection point, and the lower part of the circuit board 6 detachably disposed in the upper inner part of the grip 2.

[0039] A switch 8 is provided at the bottom of the circuit board 6 to control the opening and closing of the lamp beads 7. At the same time, a button 5 is provided on the outside of the grip 2. The button 5 is in contact with the switch 8, and pressing the button 5 achieves the effect of pressing the switch 8.

[0040] Specifically, the bottom of the outer lens 1 is fitted onto the top of the grip 2, and the two can be detachably connected by screws; the sealing structure includes a sealing groove 10 opened on the upper annular surface of the grip 2 and a sealing ring 9 set in the sealing groove 10. When installing the outer lens 1, the bottom of the outer lens 1 is fitted onto the top of the grip 2, and the bottom of the outer lens 1 covers the sealing ring 9, and then the outer lens 1 and the grip 2 are fixed with screws.

[0041] Specifically, the circuit board 6 has a socket 14 in the middle, and the handle 2 has a pin hole 11 at the top. The pin hole 11 is higher than the sealing groove 10, and the pin hole 11 and the socket 14 have the same diameter. The inner side of the top of the handle 2 has a vertical sliding groove that matches the side of the circuit board 6. During installation, the side of the circuit board 6 is slid into the sliding groove, and the socket 14 and the pin hole 11 are kept at the same height. Then, the pin 12 is inserted into the corresponding pin hole 11 and socket 14 to limit the circuit board 6 and complete the connection between the circuit board 6 and the handle 2. In order to improve the connection stability, the fit between the pin 12 and the pin hole 11 and the socket 14 can be an interference fit.

[0042] The power supply assembly also includes a battery compartment located in the lower part of the grip 2, which contains a battery. A back cover 4 is detachably connected to the bottom of the grip 2, and the battery powers the circuit board 6.

[0043] The battery can be a dry cell battery; the electrical connection between the dry cell battery and the circuit board 6 is achieved using existing conventional methods; the back cover 4 and the bottom of the handle 2 are connected by threads, that is, the back cover 4 has internal threads and the bottom of the handle 2 has external threads, so as to achieve the threaded connection between the two and achieve the effect of detachment, which facilitates the replacement of the battery later.

[0044] A buckle 3 is also fixedly provided on the outer ring surface of the handle 2. The device can be locked in a certain position, such as a shoulder strap, shoulder bag or pocket, by using the buckle 3 to improve portability.

[0045] It also includes a reflector assembly, which is located on the inner top of the outer lens 1. The reflector assembly is used to reflect light to the inner lens 16. The reflector assembly is mainly used to reflect the light emitted upward from the lamp source. That is, the light emitted by the lamp bead 7 is diffused and will also diffuse upward. In order to avoid the waste of light source caused by the light directly passing through the top of the outer lens 1, a reflector assembly is set in this solution to reflect these lights and make them reflect to the inner lens 16, thereby increasing the light intensity transmitted through the inner lens 16 and the outer lens 1, and also further increasing the range of this device.

[0046] The reflective assembly includes a reflector 13, which is snapped onto the top of the outer lens 1.

[0047] The reflective surface of the reflector 13 has the same light-gathering principle as the light-gathering surface of the existing light-gathering cover. The reflection angle can be adjusted according to actual needs, which can be achieved through existing conventional means.

[0048] Specifically, the top of the reflector 13 is provided with a cross groove 19, and the top of the inner side of the outer lens 1 is provided with a cross block 18. The reflector 13 and the outer lens 1 are engaged by inserting the cross block 18 into the cross groove 19.

[0049] A limiting structure is provided between the reflector 13 and the circuit board 6. The limiting structure includes a connecting post 17 and a locking block 15. One end of the connecting post 17 is fixedly connected to the reflector 13, and the other end is fixedly connected to the locking block 15. The bottom of the locking block 15 is engaged with the top of the circuit board 6.

[0050] Specifically, a groove is provided at the top center of the circuit board 6, and the locking block 15 engages with the groove.

[0051] With this configuration, the horizontal positioning of the reflector 13 is achieved by the snap-fit ​​between the reflector 13 and the outer lens 1. At the same time, the upper part of the circuit board 6 can be positioned by the connecting post 17 and the locking block 15 to prevent the upper part of the circuit board 6 from swinging. Conversely, the circuit board 6 can support the locking block 15 and the connecting post 17, thereby achieving vertical positioning of the reflector 13. This configuration can improve the stability of the reflector 13 and the circuit board 6.
