Description

Technical Field

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

[0002] With the rapid development of the electric vehicle industry, DC charging piles, as core charging infrastructure, are becoming increasingly important in terms of functional reliability and user experience. Currently, most mainstream DC charging piles are equipped with LCD touch screens to provide human-machine interaction during charging, and these screens often have photosensitive bars to achieve adaptive brightness adjustment.

[0003] The operating logic of the LCD touch screen and photosensitive column in existing DC charging piles is closely linked: when the photosensitive column senses light (including ambient light from the outside environment and ambient light when the user approaches), it sends a signal to the control system, triggering the screen to light up to meet the interaction needs; when no one is charging and the photosensitive column does not sense effective light, the screen automatically switches to a dimming mode, reducing the overall energy consumption of the charging pile and minimizing wear and tear caused by prolonged screen illumination. Simultaneously, to allow users to intuitively understand the charging pile's operating status, a status indicator panel is installed next to the screen. This panel uses LED beads and distinguishes between three core operating states—standby, charging, and alarm—through different colors or flashing frequencies. Due to space limitations within the charging pile, the status indicator panel and the photosensitive column are usually installed close to each other.

[0004] However, existing technology has the following drawbacks: When the charging station is in standby mode, the status indicator panel will remain lit and emit light. This light can easily shine on nearby photosensitive columns and be falsely detected by them. False detection by these photosensitive columns can then erroneously trigger the display screen to light up. When no one is operating the station, the display screen will dim again due to the lack of subsequent interaction commands. This repeated cycle causes the display screen to flicker in unattended charging scenarios. Such frequent flickering can easily lead to hardware failure of the display screen and also interferes with the user's judgment of the charging station's true operating status, severely impacting the user's charging experience. Utility Model Content

[0005] This application provides an installation structure for a charging pile display screen, which solves the problem in the prior art where the status indicator light in standby mode accidentally triggers the photosensitive column, causing the display screen to flicker in unattended charging scenarios, and easily leading to hardware failures and interfering with the judgment of the actual working status of the charging pile.

[0006] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: an installation structure for a charging pile display screen, including a fixing plate, a glass panel fixedly attached to the front side of the fixing plate, a card reader, a status indicator light, and an LCD display screen fixed on the surface of the fixing plate, a photosensitive column provided on one side of the LCD display screen, and a light-blocking block fitted outside the photosensitive column, the light-blocking block having a through hole, the light-blocking block being nested outside the photosensitive column through the through hole. The light-blocking block nested outside the photosensitive column can block the light emitted by the status indicator light continuously illuminating when the charging pile is in standby mode, preventing the photosensitive column from mistakenly triggering the display screen to turn on and off due to false sensing of light, so that the sensing end of the photosensitive column faces the glass panel, receiving only external ambient light signals, thus completely solving the problem of frequent screen flickering in unattended charging scenarios in the prior art; thereby reducing hardware wear and tear caused by frequent screen flickering, effectively extending the lifespan of the display screen, and avoiding interference from screen flickering on the user's judgment of the actual working status of the charging pile.

[0007] As a further improvement to the above solution, a sealing strip is provided on the front surface of the glass panel. The sealing strip is frame-shaped and cooperates with the fixing plate to clamp the glass panel between the two. The fixing plate is provided with rectangular holes at the corresponding positions of the card reader, status indicator and LCD screen. The card reader, status indicator and LCD screen are all fixedly installed on the rear side of the fixing plate by screws and can all be exposed through the corresponding rectangular holes.

[0008] As a further improvement to the above solution, the sealing strip is a EPDM foamed rubber strip, which is filled between the edge of the glass panel and the door panel of the charging pile; the sealing strip can prevent external dust, rainwater and other impurities from entering the interior of the charging pile.

[0009] As a further improvement to the above solution, the fixing plate is provided with multiple fixing holes around its perimeter, and the sealing strip is provided with round holes at positions corresponding to the fixing holes; thus, when screws are used to pass through the round holes and fixing holes during assembly, the sealing strip can be prevented from shifting during the fixing process, and always maintains a close fit with the edge of the glass panel and the charging pile door panel.

[0010] As a further improvement to the above solution, a card reader mounting plate is fixed to the outside of the card reader. The card reader mounting plate is fixedly connected to the rear side of the fixing plate, and the size of the card reader mounting plate is larger than the size of the card reader.

[0011] As a further improvement to the above solution, positioning holes are provided on the card reader mounting plate, status indicator lights, and LCD screen. A positioning post is provided on the rear side of the fixing plate at the position corresponding to the positioning hole, and the positioning post is provided with a threaded hole in the axial direction. The positioning post and the positioning hole cooperate to provide a reference for the installation of the card reader mounting plate, status indicator lights, and LCD screen.

[0012] As a further improvement to the above solution, the light-shielding block is provided with two through holes, one at the top and one at the bottom. The through hole at the top of the light-shielding block is fitted with a positioning post on the rear side of the fixing plate near the photosensitive post, and the through hole at the bottom of the light-shielding block is fitted with the photosensitive post. Thus, the positioning post can provide installation support for the light-shielding block.

[0013] As a further improvement to the above solution, the card reader mounting plate is made of epoxy resin.

[0014] As can be seen from the above technical solutions, this utility model has at least the following technical effects or advantages: Because the light-blocking block is nested outside the photosensitive column, it can block the light emitted by the status indicator light of the charging pile when it is in standby mode, thus preventing the photosensitive column from mistakenly triggering the display screen to turn on and off due to false light. Therefore, it solves the problem of frequent screen flickering in unattended charging scenarios in the existing technology. This reduces the hardware wear and tear caused by frequent screen flickering, effectively extending the life of the display screen, and also avoids the interference of screen flickering on the user's judgment of the actual working status of the charging pile.

Detailed Implementation To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, other embodiments obtained by those skilled in the art without creative effort are all within the scope of protection of this patent.

[0017] This utility model discloses an installation structure for a charging pile display screen, such as... Figures 1 to 5 As shown, it includes a fixing plate 1, a glass panel 2 is attached to the front side of the fixing plate 1, a card reader 3, a status indicator light 4 and an LCD screen 5 are fixed on the surface of the fixing plate 1, a photosensitive column 6 is provided on one side of the LCD screen 5, a light-blocking block 7 is fitted to the outside of the photosensitive column 6, the light-blocking block 7 is provided with a through hole 8, and the light-blocking block 7 is nested outside the photosensitive column 6 through the through hole 8.

[0018] In this embodiment, as Figure 1 As shown, the photosensitive column 6 is vertically positioned on the right edge of the LCD screen, with its sensing end facing the glass panel 2 to receive ambient light signals. A through-hole in the light-blocking block 7 extends through the front and rear ends of the block, and the diameter of this through-hole is larger than the diameter of the photosensitive column. The light-blocking block 7 fits into the side area of ​​the photosensitive column 6 from its front end.

[0019] In actual operation, when the charging pile is in standby mode, the status indicator 4 remains lit and emits light to the surroundings. Since the light-blocking block 7 is nested outside the photosensitive column 6, it can block the light emitted by the status indicator 4 from shining on the sensing area of ​​the photosensitive column 6. At this time, the photosensitive column 6 can only receive ambient light from outside the charging pile. If no one operates the charging pile, the photosensitive column 6 does not sense a valid ambient light signal and will not send a lighting command to the control system. The LCD screen 5 remains in dimmed mode to avoid unnecessary energy consumption.

[0020] In the above structure, the light-blocking block 7 is nested outside the photosensitive column 6 through the through hole 8, blocking the interference light of the status indicator 4 in the standby state. This avoids the frequent on and off of the LCD screen 5 caused by the false sensing of the photosensitive column 6, and solves the screen flickering problem in the unattended charging scenario in the prior art. At the same time, it reduces the hardware wear and tear of the LCD screen 5 caused by frequent screen flickering, and can prevent screen flickering from misleading users to judge the true working status of the charging pile.

[0021] like Figure 1 , Figure 2As shown, a sealing strip 9 is provided on the front surface of the glass panel 2. The sealing strip 9 has a frame-like structure and its shape is adapted to the edge contour of the glass panel 2. The sealing strip 9 cooperates with the fixing plate 1 to clamp the glass panel 2 between the two. The fixing plate 1 is provided with rectangular holes at the corresponding positions of the card reader 3, status indicator 4 and LCD screen 5. The card reader 3, status indicator 4 and LCD screen 5 can be fixedly installed on the rear side of the fixing plate 1 by screws.

[0022] During assembly, first attach the glass panel 2 to the front side of the fixing plate 1, then put the frame-shaped sealing strip 9 on the front edge of the glass panel 2, so that the sealing strip 9, the glass panel 2, and the fixing plate 1 are aligned. At this time, the sealing strip 9 and the fixing plate 1 together clamp the glass panel 2 from the front and rear sides. Then, align the mounting ends of the card reader 3, status indicator light 4, and LCD screen 5 with the corresponding rectangular holes from the back side of the fixing plate 1, and install and fix them.

[0023] Specifically, the sealing strip 9 is made of EPDM foamed rubber, which can adapt to different usage environments of the charging pile, such as outdoor or indoor humidity and high temperature. After assembly, the outer edge of the sealing strip 9 contacts the inner wall of the charging pile door panel (the door panel has a window that matches the sealing strip 9). Its foamed structure produces elastic deformation, completely filling the gap between the edge of the glass panel 2 and the charging pile door panel, forming a continuous sealing surface.

[0024] More specifically, each edge of the fixing plate 1 is provided with multiple fixing holes 10, all of which are circular through holes. The sealing strip 9 has a circular hole 11 at a position corresponding to each fixing hole 10. During assembly, after aligning the circular hole 11 of the sealing strip 9 with the fixing hole 10 of the fixing plate 1, the screw is passed through the circular hole 11 of the sealing strip 9 and the fixing hole 10 of the fixing plate 1, and finally fastened to the threaded hole on the charging pile door panel.

[0025] In addition, the card reader 3 is fixed to the card reader mounting plate 12, and the card reader mounting plate 12 is fixed to the fixing plate 1. The card reader mounting plate 12 is a rectangular plastic plate, and its dimensions are larger than those of the card reader 3. After the card reader mounting plate 12 is fixed to the fixing plate 1 and the card reader 3 is fixed to the card reader mounting plate 12, the card swiping section of the card reader 3 can be fully exposed through the corresponding rectangular hole in the fixing plate 1. The card reader mounting plate 12 is made of epoxy resin.

[0026] In this embodiment, the card reader mounting plate 12, the status indicator light 4, and the LCD screen 5 are all provided with positioning holes 13. A positioning post 14 is provided on the rear side of the fixing plate 1 at a position corresponding to the positioning hole 13, and the positioning post 14 has a threaded hole. During installation, the positioning holes 13 of the card reader mounting plate 12, the status indicator light 4, and the LCD screen 5 are aligned with the positioning post 14 on the rear side of the fixing plate 1 and inserted. The positioning post 14 can quickly calibrate the installation position of each component, avoiding misalignment. After positioning, the fixing screws are passed through the positioning holes 13 and the threaded holes of the positioning post 14 and tightened to complete the precise fixing of each component. This structure, through the cooperation of the positioning post 14 and the positioning hole 13, provides a reference for the installation of each component, shortens assembly time, improves installation accuracy, and avoids rework caused by manual alignment deviations.

[0027] like Figure 3 , Figure 5 As shown, the light-shielding block 7 has two through holes 8, one above the other, which are arranged parallel to each other. The upper through hole 8 is nested outside the positioning post, and the lower through hole 8 is nested outside the photosensitive post 6. During assembly, first align the upper through hole 8 of the light-shielding block 7 with a positioning post 14 near the photosensitive post 6 on the rear side of the fixing plate 1 and insert it, so that the positioning post 14 provides upper support for the light-shielding block 7. Then install the liquid crystal display screen 5, aligning the photosensitive post 6 of the liquid crystal display screen 5 with the lower through hole of the light-shielding block 7 during installation. Thus, by cooperating with the positioning post on the rear side of the fixing plate 1 and the photosensitive post 6 on the liquid crystal display screen 5, the upper and lower through holes of the light-shielding block 7 can provide installation support for the light-shielding block 7 and prevent the light-shielding block 7 from shifting.
