Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a drain nozzle connection device for an automotive charging dock. Background Technology

[0002] Currently, the drainage piping systems of car charging stations (especially electric vehicles) commonly use direct rubber hoses for connection. This traditional method has the following significant drawbacks: 1. Low assembly efficiency: The connection between the rubber hose and the drain outlet of the charging base usually requires a lot of force to assemble. Due to the limited operating space, it is difficult to apply force, which often leads to difficult and time-consuming assembly process, seriously affecting the production line cycle time.

[0003] 2. Poor connection reliability: It is difficult to ensure proper assembly of the hose. Insufficient insertion depth or uneven force can easily lead to loose connections or even detachment during use, posing a risk of water leakage.

[0004] 3. Unstable sealing performance: The sealing effect relies excessively on the elasticity of the hose itself and the operational precision of the assembly workers, making it difficult to guarantee consistency and easily leading to leakage problems caused by poor sealing.

[0005] 4. Insufficient long-term stability: Rubber hoses may age and deform under long-term use or temperature changes, further increasing the risk of loose connections and seal failure.

[0006] Therefore, it is necessary to improve the existing drainage pipe connection method of car charging sockets to improve assembly efficiency and long-term connection reliability. Utility Model Content

The inner cavity of the drain groove is connected to the inner cavity of the drain nozzle connector. A snap-fit ​​structure is symmetrically provided on the inner wall of the slot. A rubber pad with a drain hole is provided inside the slot. The rubber pad is laid on the edge of the drain groove, and the drain hole is connected to the drain groove.

[0009] Furthermore, in the aforementioned car charging dock drain nozzle connection device, the quick-connect connector and the drain nozzle connector are integrally formed.

[0010] Furthermore, in the aforementioned car charging dock drain nozzle connection device, the outer wall of the drain nozzle connector is provided with a limiting groove along the circumferential direction.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1-3 As shown.

[0026] The present invention provides a car charging dock drain nozzle connection device, including a quick-connect connector 1 and a drain nozzle connector 2. The drain nozzle connector 2 is vertically connected to the bottom of the quick-connect connector 1. In a preferred embodiment, the bottom of the quick-connect connector 1 is provided with a connecting seat 9, and the drain nozzle connector 2 is vertically connected to the side of the connecting seat 9.

[0027] The top of the fast card connector 1 has a slot 3, and the inside of the slot 3 has a drainage groove 4. The inner cavity of the drainage groove 4 is connected to the inner cavity of the drain nozzle connector 2. The connector has a specific drainage channel and groove inside to guide the smooth drainage of condensate or accidentally entered liquid in the charging socket. This groove structure ensures that the water flow path is unobstructed and avoids stagnation.

[0028] The inner wall of the slot 3 is symmetrically provided with a snap-fit ​​structure 5, which can directly and quickly engage and lock with the mechanism preset on the outer edge of the drain port of the charging base. This design abandons the traditional rubber tube connection method and realizes quick assembly and disassembly with one click or simple press.

[0029] The slot 3 is equipped with a rubber gasket 7 with drainage holes 6, which is laid on the edge of the drainage groove 4. The drainage holes 6 are connected to the drainage groove 4. A sealing rubber gasket with drainage holes is integrated at the mating end face (or axial contact surface) of the connector and the drain port of the charging base. When the snap-fit ​​structure tightly locks the connector and the charging base, the rubber gasket is uniformly compressed to form a reliable end face seal, effectively preventing liquid leakage from the connection.

[0030] In a preferred embodiment, the quick-connect coupling 1 and the drain nozzle coupling 2 are integrally formed. This integral forming avoids the leakage problems caused by assembly gaps or loose threads in traditional split couplings. Furthermore, the high material consistency prevents deformation or cracking caused by thermal expansion and contraction of couplings made of different materials. After the quick-connect coupling and drain nozzle coupling are integrated, connection / disconnection can be completed without additional tools, significantly improving operational efficiency. During maintenance, the entire assembly can be disassembled directly, avoiding the loss or misinstallation of parts due to the scattering of components in split couplings. In addition, the integrated flow channel design reduces internal turbulence and pressure drop, ensuring smoother drainage or fluid transmission.

[0031] In a preferred embodiment, the outer wall of the drain nozzle connector 2 is provided with a limiting groove 8 along the circumference to achieve quick locking and prevent the hose from accidentally loosening from the connector.

[0032] In a preferred embodiment, the end of the drain nozzle connector 2 is inverted conical in shape to facilitate the insertion of the hose.

[0033] In a preferred embodiment, the drain hole 6 of the rubber pad 7 is surrounded by anti-siphon corrugations 10. These corrugations disrupt the continuity of water flow, preventing a vacuum from forming between the rubber pad and the contact surface during drainage due to siphoning. This ensures smooth drainage and allows the rubber pad to quickly return to its original position, preventing accidental over-tightening. The corrugated structure also guides water flow towards the drain hole, reducing water residue. Furthermore, the corrugated design provides elastic deformation space under pressure, maintaining the rubber pad's seal (e.g., anti-slip and leak-proof) while releasing pressure through corrugation during drainage.

[0034] In a preferred embodiment, the drainage hole 6 of the adhesive pad 7 is a square hole. When the square hole is combined with the surrounding corrugated folds, it can more effectively disrupt the siphon effect of water flow (the right-angled edge disturbs the water flow more strongly than the round hole), preventing the adhesive pad from adhering to the flat surface and being difficult to peel off.

[0035] The car charger drain nozzle connection device provided by this utility model has the following significant advantages compared with the existing hose connection method: 1. Significantly improves assembly efficiency and convenience: The snap-fit ​​structure design enables a quick and intuitive "click" connection, requiring no special tools or forceful operation, significantly shortening assembly time, reducing labor intensity for workers, optimizing production line efficiency, and effectively reducing production costs caused by operational difficulties.

[0036] 2. Significantly enhances connection reliability and stability: The snap-locking mechanism provides a robust and stable mechanical connection, effectively preventing the joint from accidentally coming loose under conditions such as vibration, tension, or thermal expansion and contraction. It solves the core pain point of "improper assembly" in hose connections and ensures a high success rate for the connection.

[0037] 3. Excellent and stable sealing performance: The integrated sealing gasket is precisely and evenly compressed under the locking force of the snap-fit, forming a stable and reliable sealing interface, which significantly reduces the risk of leakage and improves the reliability of the drainage system. At the same time, the sealing performance is less dependent on the assembly operation, ensuring the consistency of product performance.

[0038] 3. Improve the overall quality and durability of the system: Structured joints are more resistant to external stress and environmental influences (such as aging and deformation) than pure rubber hose connections, comprehensively improving the overall performance, quality and long service life of the car charging dock drainage system.
