[0002] Chinese utility model patent CN202121521139.2 discloses a solar-powered warning lightbox with human body sensing, comprising a lightbox, a lightbox frame, a controller, a solar panel, and a human body distance sensor. The lightbox contains a warning panel and LED lights. The lightbox is installed within the lightbox frame. The controller and human body distance sensor are both mounted on the lightbox frame. The solar panel is tilted at a certain angle above the lightbox frame and fixedly connected to the lightbox frame via a connector. The solar panel, human body distance sensor, and LED lights are all electrically connected to the controller. The human body distance sensor detects the distance between a person and the warning lightbox and transmits the detection signal to the controller, which then controls the LED lights to flash or not flash. The left and right side walls of the lightbox frame each have an outwardly extending fixed wall, and each fixed wall has a fixing hole. A fixing device is connected to each fixing hole. This solar-powered warning lightbox integrates LED lighting display, human proximity control LED flashing reminder, and solar charging functions, possessing certain practicality. However, it also has the following shortcomings:

[0003] First, the structural design is not compact or aesthetically pleasing, and it has many parts, resulting in high manufacturing costs.

[0004] Secondly, both the controller and the human distance sensor are exposed outside the light box frame, making them susceptible to damage from the outdoor working environment of wind and rain, thus reducing their service life.

[0005] Third, it lacks voice reminder and warning functions, so the warning effect needs to be improved. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a power warning light box that is compact and beautiful, low in cost, long in service life, and has both light-emitting warning function and voice reminder warning function.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] An electric warning lightbox includes a front shell, a rear shell, a solar panel, a lithium battery, a warning board, an LED light, and a controller. The front shell is a rectangular shell structure with a rearward opening, including a front end wall and four first side walls extending rearward from the front end wall. The rear shell is a rectangular shell structure with a forward opening, including a rear end wall and four second side walls extending forward from the rear end wall. The front shell is fitted over and detachably connected to the rear shell, and the front end wall of the front shell is located at the LED light. At the front of the rear shell of the light box, the four first side walls of the front shell of the light box are located outside the four second side walls of the rear shell of the light box; the solar panel is installed on the upper first side wall of the four first side walls of the front shell of the light box; the lithium battery, LED light and controller are all installed inside the rear shell of the light box; the warning board is sandwiched between the inner side of the front wall of the front shell of the light box and the front end of the rear shell of the light box, and the front wall of the front shell of the light box has an opening that allows the warning content on the warning board to be displayed outward.

[0009] Furthermore, the rear shell of the light box also includes four third side walls parallel to the inner sides of the four second side walls.

[0028] The present invention will be further described in detail below with reference to the embodiments shown in the accompanying drawings.

[0029] like Figures 1 to 8 As shown, the present invention provides an electric warning light box, which includes a front shell 1, a rear shell 2, a solar panel 3, a lithium battery 4, a warning board 5, an LED light 6, and a controller 7.

[0030] The front shell 1 of the lightbox is a rectangular shell structure that opens to the rear, including a front end wall 11 and four first side walls 12, 13, 14, and 15 extending rearward from the front end wall 11. The rear shell 2 of the lightbox is a rectangular shell structure that opens to the front, including a rear end wall 21 and four second side walls 22, 23, 24, and 25 extending forward from the rear end wall 21. The front shell 1 is fitted over the rear shell 2 and detachably connected to it, with the front end wall 11 of the front shell 1 located in front of the rear shell 2, and the four first side walls 12, 13, 14, and 15 of the front shell 1 located outside the four second side walls 22, 23, 24, and 25 of the rear shell 2. The solar panel 3 is installed on the outside of the upper first side wall 12 among the four first side walls 12, 13, 14, and 15 of the front shell 1 of the light box. The lithium battery 4, LED light 6, and controller 7 are all installed inside the rear shell 2 of the light box. The warning plate 5 is sandwiched between the inner side of the front wall 11 of the front shell 1 and the front end of the rear shell 2 of the light box. The front wall 11 of the front shell 1 of the light box has an opening 111, which allows the warning content on the warning plate 5 to be displayed outward. The warning plate 5 is specifically a light-transmitting acrylic plate with warning content.

[0031] In a preferred embodiment of this utility model, the rear shell 2 of the light box further includes four third side walls 26, 27, 28, and 29, which are parallel to the inner sides of the four second side walls 22, 23, 24, and 25. The rear ends of the four third side walls 26, 27, 28, and 29 are connected to the rear end wall 21, and the front ends of the four third side walls 26, 27, 28, and 29 are flush with the front ends of the four second side walls 22, 23, 24, and 25. The warning plate 5 is sandwiched between the inner side of the front end wall 11 of the front shell 1 of the light box and the front ends of the four second side walls 22, 23, 24, and 25 and the front ends of the four third side walls 26, 27, 28, and 29. In this structure, the arrangement of the four third side walls 26, 27, 28, and 29 can increase the strength of the rear shell 2 of the light box and improve the clamping stability of the warning plate 5.

[0032] Furthermore, a first cavity 201 is formed between the four third sidewalls 26, 27, 28, and 29. Two LED lights 6 are respectively located at the upper and lower ends of the first cavity 201 to illuminate the warning board 5, so that the warning content on the warning board 5 can be clearly displayed at night or in poor lighting conditions.

[0033] Furthermore, four second cavities 202, 203, 204, and 205 are formed between the four third sidewalls 26, 27, 28, and 29 and the four second sidewalls 22, 23, 24, and 25, which are distributed on the top, bottom, left, and right sides of the first cavity 201. The lithium battery 4 is disposed in the second cavity 205 located on the right side (of course, in other examples, the lithium battery 4 can also be disposed in the second cavity 204 located on the left side), and the controller 7 is disposed in the second cavity 203 located on the bottom side.

[0034] Furthermore, it also includes a human proximity sensor and a speaker 8, which are also disposed in the second cavity 203 located on the lower side. In this example, the human proximity sensor is integrated into the controller 7 and is therefore not shown in the figure. Among the four second sidewalls 22, 23, 24, and 25, the lower second sidewall 23 has a first sound outlet 231 at the position corresponding to the speaker 8, and among the four first sidewalls 12, 13, 14, and 15, the lower first sidewall 13 has a second sound outlet 131 at the position corresponding to the first sound outlet 231. During operation, the sound emitted by the speaker 8 is transmitted outward through the first sound outlet 231 and the second sound outlet 131.

[0035] Furthermore, the device includes a switch 9 for starting or stopping the power supply of the power warning light box described in this invention. The switch 9 is also located within the lower second cavity 203. A first switch hole 232 is provided on the lower second side wall 23 of the four second side walls 22, 23, 24, and 25, corresponding to the position of the switch 9. A second switch hole 132 is provided on the lower first side wall 13 of the four first side walls 12, 13, 14, and 15, corresponding to the position of the first switch hole 232. A portion of the switch 9 protrudes outward from the first switch hole 232 and the second switch hole 132. When the power warning light box of this invention is not in use, its power can be turned off via the switch 9 to achieve energy saving.

[0036] In a preferred embodiment of this utility model, a first nut 10 is fixed to the inner side of each of the four second sidewalls 22, 23, 24, and 25. A first hole 20 corresponding to the first nut 10 is opened on each of the four second sidewalls 22, 23, 24, and 25. A second hole 30 corresponding to the first hole 20 is opened on each of the four first sidewalls 12, 13, 14, and 15. The utility model also includes several first bolts 40 corresponding to the first nut 10. Each first bolt 40 passes through the second hole 30 and the first hole 20 in sequence and is connected to the corresponding first nut 10, thereby realizing the detachable connection between the aforementioned front shell 1 and rear shell 2 of the light box.

[0037] In a preferred embodiment of this utility model, second nuts 50 are fixed to the inner sides of both the left and right sides of the rear end wall 21, and third holes 60 corresponding to the second nuts 50 are opened on both the left and right sides of the rear end wall 21. It also includes two clamping and fixing mechanisms 70. The two clamping and fixing mechanisms 70 are installed on the outer sides of the left and right sides of the rear end wall 21 by second bolts 80 corresponding to the third holes 60 and the second nuts 50. Specifically, during installation, the second bolts 80 pass through the corresponding clamping and fixing mechanisms 70 and the third holes 60 in sequence and are screwed together with the corresponding second nuts 50, thereby installing the two clamping and fixing mechanisms 70 on the outer sides of the left and right sides of the rear end wall 21. The specific structure of the two clamping and fixing mechanisms 70 is prior art and will not be described in detail here. These mechanisms allow the power warning light box of this utility model to be installed on outdoor transmission towers.

[0038] In a preferred embodiment of this utility model, two supports 90 are further provided on the outside of the first side wall 12 located at the upper end for tilting support of the solar panel 3. The supports 90 include a U-shaped main body 901, a first support 902 extending upward from one side of the opening end of the U-shaped main body 901, and a second support 903 extending downward from the other side of the opening end of the U-shaped main body 901 and on the same inclined plane as the first support 902. The bottom wall of the U-shaped main body 901 is fixedly connected to the first side wall 12 located at the upper end (e.g., by welding or screw connection). The solar panel 3 is tilted on the first support 902 and the second support 903 and is fixedly connected to both by screws.

[0039] As described above, in this utility model, the solar panel 3, lithium battery 4, LED light 6, human distance sensor and speaker 8 are all electrically connected to the controller 7. The solar panel 3 is used to receive sunlight and convert it into electrical energy for the lithium battery 4 to store. The lithium battery 4 provides electrical energy to the various electronic devices.

[0040] In a preferred embodiment of this utility model, the controller 7 also integrates a light sensor. When the light sensor detects that the ambient light is lower than a set value (e.g., at night), the controller 7 controls the LED light 6 to emit light to illuminate the warning board 5, so that the warning content on the warning board 5 can be clearly displayed at night or in poor lighting conditions. Conversely, when the light sensor detects that the ambient light is higher than a set value (e.g., during the day), the controller 7 controls the LED light 6 to not emit light. At this time, because the ambient light is good, even if the LED light 6 does not emit light, passersby can still clearly see the warning content on the warning board 5. When the human distance sensor detects that a human body is approaching to a set distance, the controller 7 controls the speaker 8 to play a set voice message to remind passersby to pay attention to safety.

[0041] The above description is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Any simple equivalent changes and modifications made in accordance with the scope of the present utility model patent application and the description of the utility model shall still fall within the scope of the present utility model patent.
