Detailed Implementation
[0024] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0025] Example 1: Please refer to Figures 1-5A mobile digital signage equipped with a solar panel includes a base 1. Four casters 2 are mounted on the bottom of the base 1, arranged in a circumferential pattern, facilitating flexible movement and positioning of the device in different locations. Four support rods 3 are symmetrically arranged in pairs on the top of the base 1. A shielding plate 301 is fixedly attached to the top of all four support rods 3 to block sunlight and rain, preventing external environmental impact on the device. A guide channel plate 302 is fixedly attached to the rear side of the shielding plate 301 to guide rainwater flow in a designated direction, preventing water accumulation and erosion of the device structure. A digital signage body 4 is located between the two front support rods 3, and a rotating rod 5 is rotatably connected between the two rear support rods 3. A first solar panel 501 is mounted on the rotating rod 5. The rotatable connections between the rotating rod 5 and the support rods 3 are all embedded with... A damping ring 19 is used to provide appropriate rotational resistance to keep the first solar panel 501 stable after opening. Mounting seats 6 are provided on the upper parts of the two support rods 3 located on the front side. Three second solar panels 7 are mounted on the mounting seats 6. These three second solar panels 7 are sequentially hinged together by hinges 8, allowing for horizontal folding and unfolding. A storage box 9 is provided on the top of the base 1. A solar energy conversion module 10 and a solar energy storage module 11 are assembled inside the storage box 9. The solar energy conversion module 10 and the solar energy storage module 11 are electrically connected to the solar panels via wires to achieve the collection, conversion, and storage of electrical energy. Ventilation and heat dissipation holes are provided on the top of the storage box 9. Four cooling fans 20 are installed inside the storage box 9 to promptly dissipate the heat generated during the electrical energy conversion and storage process.
[0026] When in use, this device can be easily moved to the desired position using the casters 2 mounted on the bottom of the base 1. Once the device reaches the designated position, the rotating rod 5 is manually rotated upwards to bring the first solar panel 501 into a horizontal position, maximizing the light-receiving area. Simultaneously, three second solar panels 7, connected by hinges 8, unfold outwards, creating a flat surface and a larger light-receiving area. Under illumination, all solar panels convert light energy into electrical energy, which is then transmitted via wires to the solar energy conversion module 10 in the storage box 9. The solar energy conversion module 10 performs voltage stabilization and inversion on the received electrical energy to adapt it to various conditions. The digital signage and other electrical components store the processed electrical energy in the solar energy storage module 11, achieving efficient energy utilization and long-term energy storage. The digital signage body 4 is continuously powered by the solar energy storage module 11, enabling normal operation during the day, night, or rainy weather, achieving all-weather information display function. It is particularly suitable for outdoor locations without mains power access. Finally, when not in use, the first solar panel 501 can be folded down along the rotating rod 5 and folded tightly against the support rod 3, while the three second solar panels 7 can be folded inward to reduce the overall volume, making it easier to transport and store, and improving the portability and safety of the equipment.
[0027] Example 2: Based on Example 1, please refer to... Figure 6 and Figure 7 The two support rods 3 on the front side are each provided with a first guide rail 12. A protective frame 13 is slidably provided on the first guide rail 12. The protective frame 13 can move vertically along the first guide rail 12 and can slide vertically up and down along the first guide rail 12. It is used to cover and protect the three second solar panels 7 when not in operation. The two support rods 3 on the rear side are each provided with a second guide rail 14. A protective plate 15 is slidably provided on the second guide rail 14. The protective plate 15 can slide vertically up and down along the second guide rail 14. It is used to cover and protect the first solar panel 501 when not in operation.
[0028] When the first solar panel 501 and the second solar panel 7 are not in use and are retracted, firstly, manually pull the protective plate 15 upward along the second guide rail 14 to cover the surface of the first solar panel 501. Then, manually pull the protective frame 13 upward along the first guide rail 12 to cover the surface of the second solar panel 7. This prevents dust, rainwater or foreign objects from contaminating or damaging the surface of the solar panels, thereby improving the service life of the equipment and the convenience of maintenance.
[0029] Please see Figure 8The base 1 has guide rods 16 vertically sliding on both sides. The bottom of the guide rods 16 is provided with a contact plate 17 to increase the contact area with the ground and improve the stability of the device. The base 1 has screw rods 18 threaded on both sides. The screw rods 18 are rotatably connected to the top of the contact plate 17. The bottom of the contact plate 17 is provided with an anti-slip texture structure to enhance the friction between the contact plate and the ground and prevent the equipment from shifting under the action of wind or other external forces.
[0030] When the device reaches the designated position, the operator can manually rotate the lead screw 18 to lower the contact plate 17 to the ground. The contact plate 17, as an extended support surface, contacts the ground, which can effectively distribute pressure and prevent the equipment from tipping over due to a high center of gravity or uneven ground. In addition, its bottom is equipped with an anti-slip textured structure, which significantly improves the coefficient of friction with the ground and prevents the device from sliding under strong winds or other external forces.
[0031] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent substitutions made within the principles of this utility model should be included within the protection scope of this utility model. Contents not described in detail in this utility model are existing technologies known to those skilled in the art.
