Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, and in particular to a display screen used in charging piles. Background Technology

[0002] As the core energy replenishment device for electric vehicles, charging piles (also known as electric vehicle charging stations or electric vehicle power supply equipment) play a crucial role in the electric vehicle ecosystem. Their basic function is to obtain electrical energy from the power grid or other energy systems and safely and efficiently transfer it to the electric vehicle's battery via charging cables, charging guns, and charging sockets to meet the energy support required for vehicle energy storage and operation. A complete charging pile system typically includes the pile structure, electrical modules, control units, human-machine interface, and safety protection devices. Among these, the human-machine interface, as the hub for information transmission between the user and the equipment, directly impacts the convenience of the charging process and user satisfaction.

[0003] Currently, to guide users through the operation process and provide real-time charging status information, most charging stations are equipped with external displays. These displays typically show various information, including charging level, tariff, time, and fault codes. However, despite meeting basic functional requirements, these displays suffer from a series of significant technical shortcomings in practical applications, severely limiting the user experience.

[0004] First, common charging pile displays perform poorly in terms of brightness uniformity. Due to limitations in backlight module design or light source layout, uneven brightness often occurs between the screen edges and the center, further reducing visibility in strong outdoor light or low-light conditions at night, thus affecting information reading efficiency. Second, many displays have low resolution and insufficient pixel density, resulting in noticeable graininess in displayed text and images, affecting not only aesthetics but also the clarity and accuracy of information recognition. Furthermore, some displays suffer from severe light crosstalk, especially when displaying high-contrast content, leading to frequent halos and light leakage, further weakening display quality. More importantly, existing displays are prone to causing eye strain after prolonged continuous use.

[0005] Therefore, how to provide a display screen for charging piles that improves the display effect and user experience has become an urgent technical problem to be solved. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to provide a display screen for charging piles, thereby improving the display effect and user experience of the charging pile display screen.

[0007] This utility model is implemented as follows: a display screen for charging piles, comprising:

[0008] A charging pile panel has a display window at the top and several studs around the display window on the back; the upper left and upper right corners of the display window are rounded to match the edge of the charging pile panel.

[0009] An LED light panel is provided with a number of LED beads and a number of first locking holes; the LED light panel is installed on the back of the charging pile panel through the first locking holes and studs, and faces the display window.

[0010] A segment code frame has a light-transmitting window in the middle and an extension at each of the four corners. Each extension has a second locking hole at its end. The segment code frame is installed on the back of the charging pile panel through the second locking holes and studs, located in front of the LED light panel, and each LED is located directly below the light-transmitting window, which faces the display window.

[0011] A light diffusion film is applied to the segment code frame.

[0012] A glass panel covers the display window.

[0013] Furthermore, it also includes:

[0014] A power supply module is connected to the LED light panel.

[0015] Furthermore, it also includes:

[0016] Several screws are used to mount the LED light panel and segment code frame on the back of the charging pile panel.

[0017] The advantages of this utility model are:

[0018] 1. The LED light panel facing the display window provides uniform backlighting, and the light diffusion film covering the segment code frame eliminates differences in brightness and light crosstalk. Combined with the light-transmitting window design of the segment code frame, the segmented characters are clearly displayed without graininess. With the support of a stable power supply module and precision screw fixing components, the system achieves a comfortable visual presentation with uniform brightness and no light leakage in outdoor strong light or low light environments. This significantly improves information readability and reduces visual fatigue for users who watch for a long time, thereby greatly improving the display effect and user experience of the charging pile display screen.

[0019] 2. The studs on the back of the charging pile panel are connected to the first locking hole of the LED light panel and the second locking hole of the segment code frame through screws, forming a modular installation method. This makes the positioning and fixing of each component more precise and faster, reducing assembly time and improving production efficiency. The upper left and upper right corners of the display window adopt a rounded corner design to match the edge of the charging pile panel, which not only enhances the aesthetics, but also avoids the potential safety risks caused by sharp edges (such as scratching users or installers), which meets ergonomics and safety standards.

[0020] 3. The LED beads on the LED light board face the light-transmitting window of the segment code frame and are covered by a light diffusion film, which achieves uniform light diffusion. This reduces glare and hot spots, ensuring that the displayed content is clearly readable under different angles and lighting conditions, making it particularly suitable for outdoor charging pile display applications. The glass panel covering the display window provides an additional protective layer while maintaining high light transmittance, preventing internal components from being contaminated or damaged, and extending the display life.

[0021] 4. The entire display screen structure adopts multi-layer protection (such as glass panel and light diffusion film), which can effectively resist outdoor environmental factors (such as dust, rain, ultraviolet rays) and physical impact, improving the reliability and durability of the charging pile under harsh conditions; the installation position of the segment code frame and LED light board ensures airtightness and reduces the risk of dust or water entering the interior.

[0022] 5. As a light source, LED beads have the characteristics of low power consumption, high brightness and long life. Combined with the power module, they provide a stable power supply, avoid display problems caused by voltage fluctuations, and reduce energy consumption and maintenance costs. The LED beads are located directly below the light-transmitting window, maximizing the use of light, reducing light loss and improving energy efficiency.

[0023] 6. The components can be quickly disassembled and replaced by screws and studs without special tools, which reduces maintenance difficulty and time, and is very beneficial for the daily maintenance and upgrade of charging piles; the modular design allows individual components (such as LED light boards and segment code frames) to be produced or replaced independently, reducing overall manufacturing costs and inventory pressure.

[0024] 7. Through optimized structural design, such as the screws on the back of the charging pile panel engaging with the locking holes of the LED light board and segment code frame via screws, modular installation is achieved, facilitating rapid assembly and maintenance. Meanwhile, the rounded corners of the display window enhance safety and aesthetics. In terms of optical performance, the LED beads face the light-transmitting window and, combined with the light diffusion film and glass panel, ensure clear and uniform display, reduce glare, and exhibit strong environmental adaptability, effectively resisting harsh outdoor conditions. High energy efficiency, stable low-power LED operation, and simplified installation and maintenance reduce costs. The overall design is novel and innovative, highly practical, and easy to mass-produce, comprehensively improving the reliability, durability, and market competitiveness of the charging pile display screen.

Combined with the light-transmitting window 31 of segment code frame 3, the segmented characters are clearly segmented without graininess. The power supply module provides stable power supply and screws are used to fix the components precisely to improve the display effect of the charging pile display screen and the user experience.

[0037] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0038] Please refer to Figures 1 to 7 As shown, a preferred embodiment of the display screen 100 for a charging pile according to the present invention includes:

[0039] A charging pile panel 1 has a display window 11 at the top and several studs 12 around the display window 11 on the back; the upper left and upper right corners of the display window 11 are rounded corners 111 that match the edge of the charging pile panel 1; the charging pile panel 1 is used to support the display screen 100.

[0040] An LED light board 2 is provided with a number of LED beads 21 and a number of first locking holes 22; the LED light board 2 is installed on the back of the charging pile panel 1 through the first locking holes 22 and studs 12, and faces the display window 11; the LED light board 2 serves as the light source of the display screen 100;

[0041] A segment code frame 3 has a light-transmitting window 31 in the middle and an extension 32 extending outward from each of the four corners. Each extension 32 has a second locking hole 33 at its end. The segment code frame 3 is installed on the back of the charging pile panel 1 through the second locking holes 33 and studs 12, located in front of the LED light panel 2. Each LED bead 21 is located directly below the light-transmitting window 31, which faces the display window 11. The segment code frame 3 is used to limit the shape of light emission.

[0042] A light diffusion film 4 is applied to the segment code frame 3; the light diffusion film 4 is used to diffuse the light transmitted through the segment code frame 3.

[0043] A glass panel 5 covers the display window 11 to provide security protection for the display screen 100.
