[0002] In the highly integrated and precision field of the automotive industry, solenoid valves, as core components of the control system, play a crucial role. They are not only widely used in the fuel injection system to achieve precise fuel supply control and optimize engine performance and fuel efficiency, but also deeply involved in the braking system, where solenoid valves with fast response regulate to ensure driving safety. At the same time, in the vehicle air conditioning system, solenoid valves also undertake the important task of regulating the refrigerant flow to maintain a comfortable in-vehicle environment.

To solve such problems, an embodiment of the present utility model provides a solenoid valve assembly.

[0045] The following further describes the present utility model in detail with reference to the drawings and specific embodiments.

[0046] As Figures 1-3 shown, an embodiment of the present utility model provides a solenoid valve assembly, including a coil unit 1. Among them, the coil unit 1 includes a mounting shell 11, a coil and a plug 13. The coil is arranged in the mounting shell 11, the plug 13 is arranged on the mounting shell 11 and is electrically connected to the coil. The plug 13 includes a plug body 131 and a guiding structure 132. The plug body 131 is connected to the mounting shell 11. The guiding structure 132 includes two guiding walls 1321 and a hook 1322 that are oppositely arranged at a predetermined distance. The guiding walls 1321 are arranged on the outer side of the side wall of the plug body along the direction parallel to the axial direction of the plug body 131, and the hook 1322 is arranged on the outer side of the side wall of the plug body 131 and is located between the two guiding walls 1321.

[0047] It should be noted that in this embodiment, as Figures 4-5 shown, the power supply plug connector 40 that cooperates with the plug 13 is usually a female connector, which has a receiving groove 401 for receiving the plug 13. A limiting groove 4011 for plugging and matching with the guiding wall 1321 is arranged on the groove side wall of the receiving groove. The distance between the two guiding walls 1321 is a predetermined distance, and this distance is usually matched with the distance between the two limiting grooves 4011.

[0048] Furthermore, as Figure 5 shown, the power supply plug connector is also provided with a buckle 4012 that cooperates with the hook 1322. The buckle 4012 is also arranged on the groove side wall of the receiving groove 401. The hook 1322 can be clamped to the buckle 4012, so as to realize the stable cooperation between the plug 13 and the power supply plug connector 40.

[0049] With such a setting, the guiding wall 1321 and the engaging hook 1322 cooperate with the limiting groove 4011 and the buckle 4012 on the power plug connector respectively, thereby ensuring that the plug 13 is accurately and conveniently plugged into the power plug connector, and improving the plugging efficiency.

[0050] Further referring to Figure 1 As shown, preferably, the guiding wall 1321 is arranged perpendicular to the side wall of the plug body 131 to ensure that the guiding wall 1321 can closely fit with the limiting groove 4011 on the power plug connector, realizing an accurate guiding function. This design enhances the stability and accuracy when the plug 13 is plugged into the power plug connector, and improves the plugging efficiency and the reliability of use.

[0051] Referring to Figure 3 As best shown in, the plug 13 is further provided with a pin 133 for realizing electrical connection. At one end of the plug body 131 away from the mounting shell 11, a mounting groove 1311 is provided. The pin 133 passes through the bottom wall of the mounting groove 1311, one end of which is firmly placed in the groove, and the other end is electrically connected to the coil to ensure smooth current transmission.

[0052] Then turning to Figure 5 As shown, the power plug connector 40 further includes a plugging column 402 located in the receiving groove 401. The plugging column 402 is arranged on the bottom wall of the receiving groove 401 and cooperates with the mounting groove 1311. A pin hole 4021 is provided at one end of the plugging column 402 facing the pin 133, and a conductor capable of being electrically conductive with the pin 133 is provided in the pin hole. When the plugging column 402 is plugged into the mounting groove 1311, the pin 133 is plugged into the pin hole 4021. Through the further plugging cooperation between the plugging column 402 and the mounting groove 1311, the plug 13 can be more accurately positioned when plugged into the power plug connector 40. Thus, the plugging effect and the plugging efficiency are ensured.

[0053] Preferably, the plug body 131 is designed as a regular quadrangular prism for easy gripping and plugging; the mounting groove 1311 is designed as a cylinder, and the pin 133 is arranged on the bottom wall of the cylindrical mounting groove 1311.

[0054] Further preferably, the regular quadrangular prism-shaped plug body 131 and the cylindrical mounting groove 1311 are coaxially arranged to ensure accurate alignment and stable structure during plugging.

[0055] Furthermore, the plug body 131, the guiding wall 1321 and the hook 1322 thereon are manufactured by an integral molding process, ensuring the overall strength and stability of the structure. This design not only simplifies the production process but also improves the durability of the plug, making it less likely to deform or be damaged during long-term use.

[0056] Optionally, in this embodiment, the mounting shell 11 and the plug body 131 are designed to be integrally molded, enhancing the overall mechanical strength and sealing performance and simplifying the assembly process.

[0057] Furthermore, the hook 1322 is precisely designed to ensure that its distance to any one of the two guiding walls 1321 is equal. Specifically, Figure 3 in it, the distance between the hook 1322 and one of the guiding walls 1321 is D1, and the distance between the hook 1322 and the other guiding wall 1321 is D2, and D1 and D2 are equal. This symmetric layout not only improves the structural balance of the plug 13 but also ensures uniform force when mating with the power plug connector, further enhancing the stability and reliability of the plug-in connection.

[0058] Referring to Figure 2 the best display of, the solenoid valve assembly in the present utility model further includes a valve body 2 and a connection unit 3 to achieve the complete structure of the solenoid valve assembly.

[0059] The connection unit 3 is specifically composed of a mounting post 31 and a clamping member 32. The mounting post 31 is fixed on the valve body 2, and the clamping member 32 is connected to the mounting post 31.

[0060] The mounting shell 11 of the coil unit 1 is sleeved on the mounting post 31 to achieve a stable connection with the valve body 2. At the same time, its two sides are respectively in close contact with the valve body 2 and the clamping member 32, ensuring the overall structural stability and sealing performance of the solenoid valve assembly, effectively preventing external impurities and moisture from invading, and extending the service life.

[0061] In summary, the embodiments of the present utility model achieve the following technical effects:

[0062] The guiding wall 1321 and the hook 1322 cooperate with the limiting groove 4011 and the buckle 4012 on the power plug connector respectively, thus ensuring the accurate and convenient plug-in connection of the plug 13 and the power plug connector and improving the plug-in efficiency.
