When detailed data analysis of the usage of charging piles is required, such as charging time, charging power, user behavior and other large amounts of data are collected and transmitted to the data processor in real time, a reliable and high-speed connection interface structure is required to ensure stable data transmission.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figures 1 to 3 This utility model provides an embodiment of a connection interface structure for a charging pile data processor, comprising a housing 1, which serves as the foundational support for the overall structure, with its front portion securely connected to housing 2 2. Housing 1 is made of polycarbonate, a material with high strength, high toughness, and excellent insulation properties. Polycarbonate provides reliable protection for the connection interface structure while ensuring stable performance in a variety of complex environmental conditions.

[0031] Housing 2 is made of aluminum alloy, which offers advantages such as light weight, high strength, and corrosion resistance. An annular ring 3 is fixedly connected to the top of the front of housing 2. Multiple pins 14 are evenly distributed along the inner wall of the rear side of the ring. These pins 14 play a key role in data transmission and charging, establishing electrical connections with external devices to enable data and power transfer. The design of the annular ring 3 effectively protects the pins 14 and facilitates accurate docking with external devices.

[0032] The front bottom of housing 2 is fixedly connected to the square ring 4. Jacks 13 are evenly distributed along the rear inner wall of the square ring 4. Jacks 13 and pins 14 work together to transmit data and power. The top of the square ring 4 is securely connected to the bottom of the annular ring 3, forming a single integrated connection interface. The interior of the square ring 4 defines an inner cavity 5, which provides space for the internal components of the connection interface structure to be installed and operated.

[0033] A sliding ring 6 is slidably connected to the inner wall of the inner cavity 5. The rear side of the sliding ring 6 is fixedly connected to a hollow column 7, which provides support and guidance for the internal components of the interface structure. A square opening 8 is defined at the top of the hollow column 7, which cooperates with a stop assembly to ensure the stability of the hollow column 7 during movement.

[0034] The limiter assembly includes a square slider 12, the bottom of which is fixedly connected to the exterior of the fixed column 10. The exterior of the fixed column 10 is fixedly connected to the rear inner wall of the inner cavity 5, providing stable support for the limiter assembly. The exterior of the square slider 12 slides against the inner wall of the square opening 8. In this way, the limiter assembly can limit the range of motion of the hollow column 7, preventing it from deflecting or becoming unstable during movement.

[0035] The rear side of the hollow column 7 is fixedly connected to the fixed circular plate 9, and the outer portion of the fixed column 10 is slidably connected to the interior of the hollow column 7 and also slidably connected to the interior of the fixed circular plate 9. This design enables the fixed column 10 to provide stable support and guidance for the hollow column 7 and the fixed circular plate 9.

[0036] The hollow column 7 is sheathed with telescopic springs 11. The front sides of the multiple telescopic springs 11 are fixedly connected to the rear side of the sliding ring 6, and the rear sides of the telescopic springs 11 are fixedly connected to the front side of the fixed circular plate 9. The telescopic springs 11 play an important role in the connection interface structure. They can provide elastic restoring force for the sliding ring 6, ensuring that the sliding ring 6 can fit tightly against the external device after contact, achieving a good sealing effect.

[0037] The exterior of the fixed circular plate 9 slides against the inner wall of the inner cavity 5, transmitting force and maintaining structural stability within the interface structure. When the sliding ring 6 is subjected to external pressure, it transmits the force through the hollow column 7 to the fixed circular plate 9. The fixed circular plate 9 then transmits the force to the telescopic spring 11, compressing it. When the external pressure disappears, the telescopic spring 11 transmits the force to the sliding ring 6 through the fixed circular plate 9 and the hollow column 7, causing it to return to its original position.

[0038] In summary, this connection interface structure for the charging pile data processor achieves stable data transmission and reliable charging control through its carefully designed components, providing a strong guarantee for the efficient operation of the charging pile.

[0039] Working Principle: Casing 2 is accurately placed on the transmission outlet. During this process, the pressure generated by the placement of casing 2 causes the sliding ring 6 to begin to compress. Under external compression, the sliding ring 6 moves according to its structural characteristics and mechanical principles. During this movement, the sliding ring 6 leverages its connection with the hollow column 7, driving the hollow column 7 to move synchronously. Driven by the sliding ring 6, the hollow column 7 further drives the fixed circular plate 9 to slide.

[0040] When the sliding ring 6 is fully in contact with the transmission port, the telescopic spring 11 begins to function. Due to its inherent stress characteristics, the telescopic spring 11 exerts a counterforce on the sliding ring 6. This stress forces the sliding ring 6 to fit tightly against the transmission port, creating a seal. This sealing action effectively prevents impurities such as dust and moisture from entering the interface.

[0041] Impurities such as dust and moisture entering the interface will have a negative impact on the contact points of the interface. Impurities cause the contact points to become unclean and wet, thereby increasing the contact resistance. The increase in contact resistance will have a negative impact on the stability of the electrical connection, easily leading to problems such as unstable data transmission and unreliable charging control. The sealing effect of the sliding ring (6) keeps the contact points clean and dry, thereby reducing the contact resistance.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
