Description

Technical Field

[0001] This utility model relates to the field of charging pile touch screen technology, specifically to a capacitive touch screen for charging piles. Background Technology

[0002] Currently, most charging pile displays use a glass cover (with capacitive touchscreen) and aluminum sheet metal, assembled with the display part (including: display screen, display screen mounting shell and PCB (Printed Circuit Board). Generally, the touch sensor and glass cover are glued together using OCA (Optical Clear Adhesive) to form the capacitive touchscreen. The glass cover is then glued to the aluminum sheet metal, and the touch sensor's FPC (Flexible Printed Circuit Board) is connected to the PCB. The display screen is fixed to the PCB using the display screen mounting shell, and finally, the PCB is fixed to the screw posts of the aluminum sheet metal with screws.

[0003] Current capacitive touchscreens all use a fully laminated structure of glass cover and touch sensor. Therefore, if the glass cover is damaged, the touch sensor must also be replaced. Since the touch sensor's FPC is connected to the PCB inside the display mounting shell, the display mounting shell must also be disassembled to completely separate the display from the glass cover. This increases the cost of replacing the glass cover and makes the replacement process more complicated and cumbersome. Therefore, this device provides a capacitive touchscreen for charging piles. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a capacitive touch screen for charging piles, thereby solving the aforementioned technical problems.

[0005] The present invention adopts the following technical solution: including a glass cover plate, aluminum sheet metal, screw posts, a sensor, single-sided adhesive foam, double-sided adhesive foam, a fixed iron shell, a display screen, a PCB, an FPC, and VHB double-sided adhesive. The aluminum sheet metal is attached to the glass cover plate with VHB double-sided adhesive. The double-sided adhesive foam is connected to the fixed iron shell. The sensor is located inside the aluminum sheet metal. Several screw posts are provided. The PCB is connected to the aluminum sheet metal by several screw posts. The fixed iron shell is fixed on the PCB. The FPC is located at the lower end of the sensor. The display screen is located inside the fixed iron shell.

[0006] Furthermore, the display screen is an industrial-grade liquid crystal display screen.

[0007] Furthermore, the sensor and the glass cover are designed to be separate.

[0008] Furthermore, the SENSOR is a surface capacitance high-sensitivity sensor made of ITO glass.

[0009] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0010] This invention employs a structure that separates the touch sensor and the glass cover. By separating the cover and the touch sensor, if the glass cover needs to be replaced, the touch sensor does not need to be replaced, reducing maintenance costs. Furthermore, the touch sensor and the glass cover are bonded together using single-sided adhesive foam, which serves both as a buffer during assembly and as a seal to prevent dust. Additionally, repairs are simpler and more convenient; the glass cover can be replaced by removing the screws securing the PCB to the aluminum sheet metal, eliminating the need to separate the touch sensor's FPC from the PCB to remove the PCB, greatly improving repair efficiency.

[0021] This utility model provides a capacitive touch screen for a charging pile, including a glass cover plate 1, an aluminum sheet metal 2, screw posts 3, a sensor 4, single-sided adhesive foam 5, double-sided adhesive foam 6, a fixed iron shell 7, a display screen, a PCB 8, an FPC 9, and VHB double-sided adhesive 10. The aluminum sheet metal 2 is attached to the glass cover plate 1 by VHB double-sided adhesive 10. The double-sided adhesive foam 6 is connected to the fixed iron shell 7. The sensor 4 is located inside the aluminum sheet metal 2. Several screw posts 3 are provided. The PCB 8 is connected to the aluminum sheet metal 2 by several screw posts 3. The fixed iron shell 7 is fixed on the PCB 8. The FPC 9 is located at the lower end of the sensor 4. The display screen is located inside the fixed iron shell 7.

[0022] This device adopts a structure that separates the touch sensor 4 and the glass cover 1. By separating the cover and the touch sensor 4, if the glass cover 1 is replaced, the touch sensor 4 does not need to be replaced, reducing its maintenance cost. Furthermore, the touch sensor 4 and the glass cover 1 are pressed together using single-sided adhesive foam 5, which serves both as a buffer during assembly and as a seal to prevent dust. At the same time, it is also simpler and more convenient to repair. The glass cover 1 can be replaced by removing the screws that fix the PCB 8 to the aluminum sheet 2, without having to separate the FPC 9 of the touch sensor 4 from the PCB 8 to remove the PCB 8, which greatly improves maintenance efficiency.

[0023] In a further preferred embodiment of this utility model, the display screen is an industrial-grade liquid crystal display screen;

[0024] The display screen is an industrial-grade LCD screen with an operating temperature range of -30℃ to +85℃, ensuring stable operation in both high and low temperature environments.

It is suitable for charging pile touchscreens that require high-precision touch control, such as accurately responding to touch operations in humid environments or when users are wearing gloves. Duntech Semiconductor's high-sensitivity capacitive touchscreen controller uses advanced signal processing algorithms to effectively filter out environmental noise and improve the accuracy and reliability of touch detection.

[0029] This device adopts a structure in which the glass cover 1 and the touch sensor 4 are separate. That is, the touch sensor 4 is pasted on the display screen mounting shell 7 of the display part, and the FPC9 of the touch sensor 4 is directly connected to the PCB 8. A ring of single-sided adhesive foam 5 is pasted on the surface of the touch sensor 4 so that it can be tightly attached to the glass cover 1.
