[0023] As an introduction to this application, an energy storage power device is a device that stores photovoltaic or off-peak electricity for people to use. In order to observe the amount of electricity stored in the energy storage power device, a certain power display device is needed to display the amount of electricity. In related technologies, an LCD screen is used to display the remaining power of the energy storage power device; however, the display cost of an LCD screen is relatively high.

[0024] In view of the above, embodiments of this application provide a power supply box, which aims to solve at least one of the above-mentioned technical problems.

[0025] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the embodiment of this application, the power supply box includes: a cover plate 10, a bracket 20, a light guide 30, and multiple LED beads 40. The cover plate 10 has a first light-transmitting portion 11. The bracket 20 is connected to the cover plate 10 and has a second light-transmitting portion 21. The projection of the second light-transmitting portion 21 on the plane of the cover plate 10 overlaps with the first light-transmitting portion 11. Both the first light-transmitting portion 11 and the second light-transmitting portion 21 can be made of a semi-transparent black panel structure, allowing light to pass through. When there is no light, it appears black, similar to the effect of an LCD panel. The bracket 20 serves two purposes: firstly, it fixes the light guide 30 and the LED beads 40, preventing the LED beads 40 from shifting and causing the light to misalign with the light-transmitting portion; secondly, through the size design of the second light-transmitting portion 21, it can control the light emission range and prevent light leakage from affecting the display clarity. A light guide 30 is disposed on one side of the second light-transmitting part 21 and is connected to the bracket 20. The light guide 30 has multiple through holes 300 facing the second light-transmitting part 21. The light guide 30 is made of a low-transmittance material, and the outline area of ​​the through holes 300 is larger than the light-emitting area of ​​the LED beads 40 to ensure that more light emitted by the LED beads 40 is concentrated within the through holes 300. Multiple LED beads 40 are disposed on the side of the light guide 30 away from the second light-transmitting part 21, with each LED bead 40 corresponding to one of the through holes 300. In addition to its light-guiding function, the light guide 30 also provides physical protection for the LED beads 40, allowing them to be housed within the through holes 300 to prevent foreign objects from directly contacting the LED bead 40 pins and causing a short circuit. After being conducted by the light guide 30, the light emitted by the LED beads 40 passes sequentially through the second light-transmitting part 21 and the first light-transmitting part 11 to the outside. Users can determine the battery level by the number of lit LEDs. It should be understood that this application uses the cooperation of multiple LED beads 40 and light guides 30 to achieve graded display of remaining power, which has low hardware cost, simple structure, and low assembly and maintenance cost.

[0026] Please see Figure 5 , Figure 6 and Figure 8As shown, in some embodiments, the power supply box further includes a circuit board 50. The circuit board 50 is disposed on the side of the light guide 30 away from the second light-transmitting part 21 and is connected to the bracket 20. The circuit board 50 has multiple LEDs 40 on the side facing the light guide 30. It should be understood that the circuit board 50 provides a unified fixing carrier for the LEDs 40. The LEDs 40 can be precisely integrated into the side of the circuit board 50 facing the light guide 30 by surface mount soldering. The size design of the circuit board 50 and the positioning holes 500 ensure that the LEDs 40 are aligned with the through holes 300 of the light guide 30 and the second light-transmitting part 21 of the bracket 20 with zero deviation, reducing the risk of displacement of the LEDs 40 due to dispersed fixing. The circuit board 50 is directly connected to the bracket 20. If screws are used for fixing or snap-fit ​​limiting, the LEDs 40 and the circuit board 50 can be formed into a modular component. Compared with dispersed LEDs 40, modular assembly is more convenient for batch operation on the production line and improves assembly efficiency. During maintenance, only the circuit board 50 assembly needs to be directly disassembled, without the need to find or disassemble individual LEDs 40, making maintenance convenient.

[0027] Please see Figure 5 and Figure 6 As shown, in some embodiments, the bracket 20 includes a first wall 201 and a second wall 202. The first wall 201 is connected to the cover plate 10. The first wall 201 is provided with a second light-transmitting part 21. The second wall 202 surrounds the second light-transmitting part 21 and is connected to the side of the first wall 201 facing the circuit board 50. The second wall 202 and the first wall 201 together form a groove 200. The light guide 30 is housed in the groove 200. It is important to understand that the light guide 30 can be directly embedded in the groove 200, and the second wall 202 will form a physical barrier for the light guide 30 to prevent lateral displacement of the light guide 30 during assembly or use. At the same time, the depth of the groove 200 can be precisely matched with the thickness of the light guide 30. For example, if the thickness of the light guide 30 is 2mm and the depth of the groove 200 is 2mm, it ensures that the through hole 300 on the light guide 30 is completely aligned with the second light-transmitting part 21 of the first wall 201, thereby ensuring that the light from the lamp bead 40 can accurately penetrate the through hole 300 and the second light-transmitting part 21, reducing the risk of light leakage or dark areas due to misalignment. After the light guide 30 is housed in the groove 200, its side facing the first wall 201 can fit tightly against the first wall 201, reducing the gap between the two. On the one hand, this can prevent dust and moisture from entering through the gap and protect the through hole 300 of the light guide 30 from being blocked. On the other hand, the tight fit can improve the light transmission efficiency and reduce the brightness loss caused by light scattering in the gap, ensuring that the user can clearly see the lighting status, especially in a dimly lit environment, where the display clarity is better.

[0028] In some embodiments, the circuit board 50 is detachably connected to the second wall 202. When the LED bead 40 is damaged or the circuit board 50 malfunctions, such as when a single LED bead 40 burns out and the corresponding display position does not light up, or when a short circuit causes all LED beads 40 to stop working, it is not necessary to disassemble the entire bracket 20 or damage the structure. The circuit board 50 can be removed from the second wall 202 simply by removing the screws with a screwdriver or by prying open the clips. The faulty circuit board 50 can then be replaced or the LED bead 40 can be repaired directly, which greatly improves the convenience of maintenance and reduces the cost and difficulty of later maintenance.

[0029] The second wall 202 is connected to the first wall 201 to form a frame structure, which has stronger resistance to bending and deformation. When the internal components of the power supply box (such as the battery) heat up and cause the shell to expand slightly, the bracket 20 is not easily deformed due to the force, thereby reducing the risk of displacement of the light guide 30 and poor contact of the lamp bead 40 caused by the deformation of the bracket 20, and ensuring the long-term stable operation of the display module.

[0030] Please see Figure 5 and Figure 6 As shown, in some embodiments, the first light-transmitting part 11 is a mounting hole; the second light-transmitting part 21 protrudes from the first wall 201 on the side away from the second wall 202, and the second light-transmitting part 21 passes through the mounting hole. It should be understood that by using the protruding post through-hole matching method, the relative positions of the cover plate 10 and the bracket 20 are forcibly fixed from four directions: up, down, left, and right, so that the first light-transmitting part 11 and the second light-transmitting part 21 are completely coaxially aligned without any offset space, thus enhancing the connection reliability between the cover plate 10 and the bracket 20. When light originates from the lamp bead 40 and is transmitted to the outside through the through hole 300 of the light guide 30, the second light-transmitting part 21, and the mounting hole, it will not cause light leakage or dark areas due to structural misalignment, ensuring that the light from each lamp bead 40 can be transmitted completely and clearly to the user's field of vision. Especially when multiple lamp beads 40 are lit at the same time, the displayed lighting boundary is clearer, achieving zero-offset light transmission. Users can quickly distinguish the number of lit lamps and reduce the risk of misjudging the power level.

[0031] In some embodiments, the first wall 201 and the cover plate 10 are detachably connected. During assembly, the second light-transmitting part 21 of the bracket 20 can be inserted into the mounting hole of the cover plate 10 first, and the cover plate 10 and the bracket 20 can be pre-positioned by the cooperation of the two. Then, the fixing is completed by screws or buckles, reducing manual calibration steps and reducing operational errors. The second light-transmitting part 21 performs both light transmission and positioning functions, eliminating the need for additional positioning components and reducing the processing steps of the bracket 20 and the cover plate 10. For example, there is no need to drill holes in the bracket 20 to process the positioning post 301, which reduces the manufacturing cost and assembly complexity of the parts. When it is necessary to inspect the light guide 30, the lamp bead 40, and the circuit board 50, only the connector between the cover plate 10 and the first wall 201 needs to be disassembled to remove the cover plate 10 separately, improving inspection efficiency.

[0032] Please see Figure 2 and Figure 3 As shown, in some embodiments, the light guide 30 is detachably connected to the circuit board 50. It should be understood that the detachable connection can be at least one or more combinations of snap-fit ​​connections, screw fixing connections, and positioning pin and hole mating. If only the light guide 30 fails, it is not necessary to disassemble the connection between the circuit board 50 and the bracket 20; simply releasing the fixing structure between the light guide 30 and the circuit board 50 allows for the individual replacement of the light guide 30, making maintenance more convenient and fault repair more precise and efficient.

[0033] Please see Figure 6 As shown, in some embodiments, the light guide 30 is sandwiched between the circuit board 50 and the second light-transmitting portion 21. It should be understood that sandwiching the light guide 30 between the circuit board 50 and the second light-transmitting portion 21 enhances the stability of the light guide 30's fixation. Simultaneously, it reduces the distance between the light guide 30 and the LED bead 40, shortening the light transmission path and reducing light loss. The extremely short transmission path significantly reduces light scattering and attenuation in the air, improving display brightness and clarity. Using a sandwiching method reduces the fixed structure, achieving a lightweight design, while simultaneously strengthening connection stability and improving vibration resistance.

[0034] Please see Figure 3 As shown, in some embodiments, the light guide 30 has a positioning post 301 on the side away from the second light-transmitting part 21, and the circuit board 50 has a positioning hole 500, with the positioning post 301 embedded in the positioning hole 500. It should be understood that the cooperation between the positioning post 301 and the positioning hole 500 achieves assembly positioning, reduces manual calibration, and further reduces assembly deviation. Furthermore, the positioning structure further enhances the connection stability between the light guide 30 and the circuit board 50. After the positioning post 301 is embedded in the positioning hole 500, a multi-point structural constraint is formed. Even if the connecting screws between the light guide 30 and the circuit board 50 are slightly loosened, the light guide 30 will not shift laterally or longitudinally, ensuring the long-term stable alignment of the lamp bead 40 and the through hole 300, avoiding display failure due to vibration. The positioning post 301 can also form a support point between the two, dispersing compressive stress, reducing the risk of cracking of the light guide 30 or deformation of the circuit board 50, extending the component's service life, and adapting to complex operating environments.

[0035] Please see Figure 6 , Figure 7 and Figure 9As shown, in some embodiments, the power supply box also includes a light-diffusing sticker 60. The light-diffusing sticker 60 is disposed on the side of the light guide 30 facing the second light-transmitting part 21. The light-diffusing sticker 60 has multiple light-diffusing zones 600, and each light-diffusing zone 600 corresponds to a through hole 300. It should be understood that the light-diffusing zone 600 has a specific shape, thereby achieving a specific light outline and effect display. The light-diffusing sticker 60 is made of a microstructure diffusion film or a semi-transparent frosted material. The tiny textures or frosted particles on its surface can diffuse and refract the point light source emitted by the LED beads 40, dispersing the concentrated light into a uniform surface light source. Furthermore, the light-diffusing zone 600 corresponds one-to-one with the through hole 300 of the light guide 30, ensuring that the light from each LED bead 40 is only uniformly distributed within the corresponding light-diffusing zone 600, and will not be confused with the light from adjacent LED beads 40. In complex lighting environments, such as direct indoor lighting or cloudy outdoor lighting, the on / off state can be clearly distinguished, avoiding the problem of misjudging the number of lights on due to uneven brightness. The uniform light sticker 60 can reduce the brightness difference of individual LED beads 40 by adjusting the uniformity, so that the display brightness of multiple lit LEDs tends to be consistent, thus improving the overall display coordination.

[0036] Please see Figure 3 , Figure 6 and Figure 7 As shown, in some embodiments, the power supply box further includes a seal 70, which is sandwiched between the first wall 201 and the cover plate 10 and located on the outer periphery of the second light-transmitting part 21. It should be understood that the seal 70 is made of an elastic material. The seal 70, through compression deformation, precisely fills the connection gap between the first wall 201 and the cover plate 10, forming a sealed barrier around the second light-transmitting part 21, improving the protection level, blocking dust intrusion, resisting splashing water and low-pressure water spray, and preventing external dust and water from entering the equipment from the gap between the first wall 201 and the cover plate 10 in harsh environments such as outdoors and dusty environments. This prevents dust and water from penetrating to other parts of the bracket 20 or the core components inside the power supply box (such as the battery and circuit board 50), avoiding faults such as short circuits and component corrosion. The sealing element 70 can serve as an elastic buffer layer to buffer the tightening pressure when assembling the first wall 201 and the cover plate 10, prevent the plastic first wall 201 or cover plate 10 from deforming due to rigid compression, and absorb the vibration energy during handling and transportation, reduce the collision and friction between the first wall 201 and the cover plate 10, avoid loosening of connecting screws and displacement of the cover plate 10, and ensure the overall structural stability of the bracket 20.

[0037] Please see Figure 6 and Figure 7As shown, in some embodiments, the first wall 201 has a stop 203 on the side facing the cover plate 10, and the stop 203 surrounds the second light-transmitting part 21; the sealing member 70 is sleeved between the second light-transmitting part 21 and the stop 203. It should be understood that the stop 203 can precisely limit the sealing member 70 from the outside, preventing the sealing member 70 from shifting during assembly or use, ensuring that the sealing member 70 always surrounds the second light-transmitting part 21 and precisely covers the gap area between the first wall 201 and the cover plate 10, preventing the seal from failing due to displacement of the sealing member 70. At the same time, under the dual constraint of the second light-transmitting part 21 and the stop 203, the sealing member 70 can fill the gap more evenly when squeezed, forming a tighter sealing barrier, improving the protection level, and effectively blocking dust and splashing water from entering from the gap between the first wall 201 and the cover plate 10, preventing dust and water from affecting the core components inside the power supply box. Furthermore, the thickness of the stop portion 203 is less than the thickness of the seal 70, preventing the seal 70 from being excessively compressed, ensuring the sealing performance and elastic deformation resistance of the seal 70, and extending its service life. The elastic buffering capacity of the seal 70 can alleviate the squeezing damage to the first wall 201 and the cover plate 10 caused by assembly pressure, absorb vibration impact, ensure structural stability, and has low overall design cost and convenient assembly. Without affecting the function of other components, it significantly improves the protection reliability and structural durability of the power supply box.

[0038] This application also discloses a lighting assembly, including: a bracket 20, a light guide 30, and a plurality of LED beads 40. The bracket 20 has a second light-transmitting portion 21. The light guide 30 is disposed on one side of the second light-transmitting portion 21 and is connected to the bracket 20. The light guide 30 has a plurality of through holes 300, which face the second light-transmitting portion 21. The plurality of LED beads 40 are disposed on the side of the light guide 30 away from the second light-transmitting portion 21, and the LED beads 40 are correspondingly disposed with the through holes 300. It should be understood that the lighting assembly disclosed in this application achieves precise and efficient light transmission through the coordinated design of the bracket 20, light guide 30, and LED beads 40. The LED beads 40 correspond one-to-one with the through-holes 300 of the light guide 30, allowing light to be directionally transmitted to the second light-transmitting part 21 of the bracket 20 through the through-holes 300, avoiding light scattering and loss. The light guide 30 is fixedly connected to the bracket 20, ensuring long-term precise alignment between the through-holes 300 and the second light-transmitting part 21, guaranteeing stable light output. The independent arrangement of multiple LED beads 40 enables hierarchical display functions. The overall structure is compact and easy to assemble. With low-cost investment, it ensures high light utilization while meeting diverse display needs, making it suitable for status indication scenarios in power supply boxes and other equipment. Its hardware cost is low, its structure is simple, and its assembly and maintenance costs are low.
