Technical Field

[0001] This utility model relates to the field of light box technology, specifically a solar light box. Background Technology

[0002] Solar light boxes, as a multifunctional lighting display device powered by solar energy, combine lighting and advertising functions and are widely used in urban construction and commercial promotion.

[0003] Its working principle is clear and efficient: solar energy is converted into electrical energy through solar panels and stored in batteries such as lead-acid maintenance-free batteries and lithium iron phosphate batteries. When night falls or the ambient light is insufficient, the controller will release the electrical energy stored in the battery according to the preset light control or time control mode to light up the LED light source, thereby realizing the dual functions of lighting and advertising display.

[0004] However, some existing solar light boxes have certain limitations: the solar panels installed on their tops are designed at a fixed angle and cannot be adjusted. This design flaw makes it difficult for the light boxes to adapt to changes in latitude, seasons, and the dynamic changes in the angle of sunlight each day during installation and use. As a result, the solar panels cannot always maintain the optimal position for receiving sunlight, greatly reducing the efficiency of light energy conversion. This leads to insufficient energy stored in the battery, making it difficult to support the light box for long periods of stable operation at night, thus affecting the effectiveness and practicality of the equipment.

[0005] Therefore, a solar-powered light box is proposed. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: See Figure 1 — Figure 4 A solar-powered light box includes a base 1, with anti-slip components 2 installed inside each of the two sides of the base 1. A box body 9 is welded to the top of the base 1. A display window 4 is installed on one side of the box body 9 via a hinge. A fixing frame 8 is fixed to the top of the box body 9 by bolts. A second solar panel 7 is installed on the top of the fixing frame 8 by bolts. A first solar panel 6 is rotatably installed on each side of the second solar panel 7. Two cylinders 5 are rotatably installed on each side of the fixing frame 8. The output end of the cylinders 5 is connected to the bottom of the first solar panel 6 via a rotating shaft. An energy storage converter and a battery are installed inside the box body 9. The energy storage converter is electrically connected to the first solar panel 6, the second solar panel 7, and the battery. An LED light source is also provided inside the box body. The LED light source is electrically connected to the battery and its switching is controlled by a controller.

[0019] A support rod 10 is welded to each side of the second solar panel 7, and one end of the first solar panel 6 is rotatably sleeved on the outside of the support rod 10.

[0020] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, during use, the base 1 is moved to the designated position. Since a fixing frame 8 is installed on the top of the box 9, and a second solar panel 7 is fixed on the top of the fixing frame 8, and a first solar panel 6 is rotatably installed on both sides of the second solar panel 7, and two cylinders 5 are connected to the bottom of the first solar panel 6, the angle of the first solar panel 6 can be changed by controlling the extension and retraction of the output end of the cylinders 5. During use, the installation angle of the two first solar panels 6 can be adjusted according to the angle of sunlight, so as to fully contact the sunlight, improve the light energy conversion efficiency, and ensure that the light box can work stably for a long time at night. Then, the light energy is converted into electrical energy and stored in the battery by the energy storage converter installed inside the box 9. Then, the display window 4 is opened and the display poster is installed inside the box 9 to perform the light display.

[0021] Example 2: Four fixed casters 3 are bolted to the bottom of the base 1, and the four fixed casters 3 are located at the four corners of the bottom of the base 1. The anti-slip component 2 includes a screw 204 connected to the inside of the base 1 by threaded engagement, and a rocker wheel 201 is welded to the top of the screw 204. The bottom of the screw 204 is connected to a pressure plate 207 through a bearing. An anti-slip rubber sleeve is fitted on the outer side of the rocker wheel 201. The surface of the rubber sleeve has a textured surface. A support slide rod 202 is welded to each of the two sides of the top of the pressure plate 207, and multiple rubber supports are fixed at equal intervals at the bottom of the pressure plate 207. The anti-slip mat 206 has a grid-like anti-slip texture on the bottom. The top of the support rod 202 slides through the interior of the base 1, and the top of the support rod 202 is welded with a limit plate 205. The display window 4 is made of transparent tempered glass. The hinge connection between the display window 4 and the cabinet 9 is equipped with a sealing strip. The display window 4 is equipped with a lock to lock the display window 4 and the cabinet 9. The controller has two control modes: light control and time control. The mode can be switched and the parameters can be set by an external remote control. The controller also has overload protection, short circuit protection and overcharge and over-discharge protection functions.

[0022] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, since a fixed caster 3 is installed at each of the four corners of the bottom of the base 1, the fixed caster 3 installed at the bottom of the base 1 allows the operator to easily move the entire device. After the device is moved to the designated position, rotating the rocker wheel 201 can drive the lead screw 204 to rotate. Since the lead screw 204 is connected to the base 1 by a threaded engagement, and the bottom of the lead screw 204 is connected to the top of the pressure plate 207 by a bearing, the rotation of the lead screw 204 can drive the pressure plate 207 to move up and down. By controlling the pressure plate 207 to move downward, the rubber anti-slip pad 206 installed at the bottom of the pressure plate 207 can fully contact the ground, which can enhance the stability of the device when it is placed and prevent the device from shifting position. Working Principle: During the day, the first and second solar panels on the top of the lightbox absorb solar energy, which is then converted into electrical energy by an energy storage converter installed inside the box. The electrical energy is then stored in the battery. The first solar panel rotates around a support rod under the drive of a cylinder, adjusting its angle according to the angle of sunlight to maximize solar energy absorption and improve energy collection efficiency. When night falls or ambient light is insufficient, the controller inside the box activates. According to a preset light control mode, when the ambient brightness is detected to be lower than a set value, the controller automatically connects the circuit between the battery and the LED light source, illuminating the LED light source to provide lighting for the displayed posters inside the lightbox, thus achieving the advertising display function. Alternatively, a time control mode can be used to automatically turn the LED light source on or off according to a preset time. When the lightbox needs to be moved, the brakes on the fixed casters are released, and the lightbox is moved to the designated position by pushing the casters. The brakes are then locked to initially fix the lightbox in place. Then, by rotating the rocker wheel of the anti-slip component, the lead screw rotates within the base. Because the lead screw engages with the base's threads, its rotation causes the bottom pressure plate to move downwards. The support slide moves synchronously with the pressure plate and acts as a guide until the rubber anti-slip pad at the bottom of the pressure plate makes tight contact with the ground, further enhancing the lightbox's stability and preventing positional shifts during use. The controller constantly monitors the circuit status and automatically cuts off the circuit in case of output overload, output short circuit, input reverse connection, or battery overcharging or over-discharging, protecting the battery, LED light source, and other electrical components from damage and ensuring the safe operation of the lightbox. Simultaneously, the lock on the display window prevents unauthorized personnel from opening the cabinet, protecting the internal display content and electrical components.
