Description

Technical Field

[0001] This utility model belongs to the field of vehicle technology, specifically relating to an electromagnetic valve, an electronically controlled air suspension system, and a vehicle. Background Technology

[0002] The Electronically Controlled Air Suspension System (ECAS) includes a height sensor, electronic control unit (ECU), actuators, and solenoid valves. The ECAS system adjusts vehicle height, suspension stiffness, and damping through air springs and shock absorbers to adapt to various vehicle operating conditions. Among these components, the solenoid valves are the "hands and feet" of the automotive electronic control system, playing a crucial role in the control of the ECAS electronically controlled air suspension system.

[0003] As a key component of ECAS (Electronic Control System), the solenoid valve is used to control the flow rate and velocity of fluids (for functions such as inflation, deflation, and locking the air pressure in the air suspension system). The solenoid valve mainly consists of a valve core, armature, solenoid coil, valve body, and spring. When the coil is energized or de-energized, the coil's magnetic field generates a magnetic force on the magnet, which in turn overcomes the spring force, generating an electromagnetic force that drives the valve core to move, thus closing or opening the valve body. The valve core acts as an intermediary between the valve body and the solenoid coil, playing a crucial role in both suppressing the gas in the solenoid valve and being attracted by the electromagnetic force. An important component in the solenoid valve core structure is the rubber plug, used to suppress the gas in the air passage of the solenoid valve body, ensuring the airtightness of the solenoid valve. However, in existing technologies, the rubber plug in the valve core is prone to displacement during operation, leading to air leakage in the entire solenoid valve and consequently causing vehicle misalignment. Utility Model Content

[0004] Therefore, this utility model provides a solenoid valve that can solve the technical problem that the rubber plug of the valve core of the solenoid valve is prone to displacement during operation, resulting in air leakage of the entire solenoid valve.

[0005] To address the aforementioned problems, this utility model provides a solenoid valve, comprising an electromagnetic component, a valve core assembly, and a valve body. The valve body has an inlet channel, an outlet channel, and a first groove. The two ends of the inlet channel are respectively connected to the outside of the valve body and the first groove. One end of the inlet channel connected to the first groove is an exhaust port. The two ends of the outlet channel are respectively connected to the outside of the valve body and the first groove. The valve core assembly includes a valve core and a limiting tube. The limiting tube is assembled on the electromagnetic component, and the end of the limiting tube away from the electromagnetic component extends into the first groove. The valve core is disposed within the limiting tube, and the valve core can slide along the limiting tube under the action of the electromagnetic component to close or open the exhaust port.

[0006] In some embodiments, an auxiliary limiting component is assembled on the valve body, and a limiting hole is formed on the auxiliary limiting component, the limiting hole corresponding to the first groove, and the limiting tube extends into the first groove after passing through the limiting hole.

[0007] In some embodiments, the limiting tube is welded to the auxiliary limiting component.

[0008] In some embodiments, a second groove is also formed on the valve body, the first groove is formed on the bottom wall of the second groove, and the auxiliary limiting member has a protrusion that is inserted into the second groove.

[0009] In some embodiments, the auxiliary limiting component is assembled onto the valve body by fasteners.

[0010] In some embodiments, the auxiliary limiting component has a first threaded hole, the valve body has a second threaded hole, and the fastener is threadedly connected to both the first threaded hole and the second threaded hole.

[0011] In some embodiments, the electromagnetic component has a snap-fit ​​structure, and the auxiliary limiting component has a snap-fit ​​engagement structure, wherein the snap-fit ​​structure engages with the snap-fit ​​engagement structure.

[0012] In some embodiments, the valve core assembly further includes a resilient member that is clamped between the electromagnetic assembly and the valve core.

[0013] This utility model also provides an electronically controlled air suspension system, including the aforementioned solenoid valve.

[0014] This utility model also provides a vehicle including the aforementioned electronically controlled air suspension system.

[0015] The electromagnetic valve, electronically controlled air suspension system, and vehicle provided by this utility model have the following beneficial effects: By placing the valve core inside the limiting tube, which extends from the electromagnetic component into the first groove, the movement of the valve core is effectively limited by the limiting tube, ensuring that the valve core does not deviate and that it is always aligned with the exhaust port. This allows the valve core to accurately close or open the exhaust port, thus avoiding air leakage caused by the solenoid valve not closing the air hole properly, and ensuring the stability of the solenoid valve's operation.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0020] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0021] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0022] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0023] See also Figures 1 to 5 As shown, according to an embodiment of the present invention, a solenoid valve is provided, including an electromagnetic component 1, a valve core component 2, and a valve body 3. The valve body 3 has an air inlet channel 4, an air outlet channel 5, and a first groove 6. The two ends of the air inlet channel 4 are respectively connected to the outside of the valve body 3 and the first groove 6. One end of the air inlet channel 4 connected to the first groove 6 is an exhaust port 7. The two ends of the air outlet channel 5 are respectively connected to the outside of the valve body 3 and the first groove 6. The valve core component 2 includes a valve core 21 and a limiting tube 22. The limiting tube 22 is assembled on the electromagnetic component 1, and the end of the limiting tube 22 away from the electromagnetic component 1 extends into the first groove 6. The valve core 21 is disposed in the limiting tube 22. Under the action of the electromagnetic component 1, the valve core 21 can slide along the limiting tube 22 to close or open the exhaust port 7.

[0024] In this technical solution, by placing the valve core 21 inside the limiting tube 22, which extends from the electromagnetic component 1 into the first groove 6, the movement of the valve core 21 is effectively limited by the limiting tube 22. This ensures that the valve core 21 does not shift, keeping it aligned with the exhaust port 7. Consequently, the valve core 21 can accurately close or open the exhaust port 7, preventing air leakage caused by incomplete closure of the air orifice and thus ensuring the stability of the solenoid valve's operation. The electromagnetic component 1 includes an iron core and a coil, with the limiting tube 22 assembled on the iron core.

[0025] See also Figure 2 and Figure 4 As shown, an auxiliary limiting component 8 is assembled on the valve body 3. The auxiliary limiting component 8 has a limiting hole 9 that penetrates it. The limiting hole 9 corresponds to the first groove 6. The limiting tube 22 passes through the limiting hole 9 and extends into the first groove 6. It should be noted that... Figure 1 The auxiliary limiting component 8 is not shown in the text. Figure 2 Valve body 3 is not shown in the text, which can... Figure 1 and Figure 2 The technical solution of this application should be understood in combination.

[0026] In this embodiment, when the limiting tube 22 extends into the first groove 6 through the limiting hole 9 of the auxiliary limiting component 8, the auxiliary limiting component 8 can assist in limiting the limiting tube 22, thereby facilitating the alignment of the limiting tube 22 with the first groove 6, and further facilitating the alignment of the valve core 21 with the exhaust port 7. The valve core 21 includes a valve core body 211 and a sealing plug 212 mounted on the valve core body 211. The sealing plug 212 is made of rubber, and the alignment of the valve core 21 with the exhaust port 7 refers to the alignment of the sealing plug 212 with the exhaust port 7.

[0027] In one specific implementation, the limiting tube 22 is welded to the auxiliary limiting component 8, so that the limiting tube 22 can also be fixed by the auxiliary limiting component 8.

[0028] See also Figure 1 and Figure 2 As shown, a second groove 10 is also formed on the valve body 3, and a first groove 6 is formed on the bottom wall of the second groove 10. The auxiliary limiting component 8 has a protrusion 11, which is inserted into the second groove 10.

[0029] In this technical solution, by inserting the protrusion 11 of the auxiliary limiting component 8 into the second groove 10, it is beneficial for the auxiliary limiting component 8 to be stably assembled on the valve body 3, and also for the correspondence between the limiting hole 9 and the first groove 6. The limiting hole 9 penetrates the area where the protrusion 11 is located. It should be noted that the cross-sectional shape of both the first groove 6 and the second groove 10 is circular, with the second groove 10 having a diameter of 3cm and a depth of 2mm. The cross-sectional shape of the protrusion 11 is annular, with an outer diameter of 2.9cm, an annular thickness of 1mm, and an annular height of 2mm.

[0030] In one specific implementation, the auxiliary limiting component 8 is assembled onto the valve body 3 using fasteners. This allows the auxiliary limiting component 8 to be fixed onto the valve body 3 using fasteners, further ensuring the assembly stability of the auxiliary limiting component 8 on the valve body 3.

[0031] See also Figure 3 and Figure 4 As shown, the auxiliary limiting component 8 has a first threaded hole 12 and the valve body 3 has a second threaded hole 13. The fastener is threaded into both the first threaded hole 12 and the second threaded hole 13, which makes the auxiliary limiting component 8 and the valve body 3 detachable. If the relevant components need to be repaired or replaced, they can be easily disassembled.

[0032] See also Figure 4 and Figure 5 As shown, the electromagnetic component 1 has a snap-fit ​​structure 14, and the auxiliary limiting component 8 has a snap-fit ​​engagement structure 15. The snap-fit ​​structure 14 and the snap-fit ​​engagement structure 15 engage in a snap-fit ​​engagement. It should be noted that... Figure 2 The focus is only on demonstrating the principle of electromagnetic component 1. Figure 5 This shows a physical image of electromagnetic component 1, therefore Figure 2 Electromagnetic component 1 and Figure 5 The shape of the electromagnetic component 1 varies considerably.

[0033] In this embodiment, when the snap-fit ​​structure 14 on the electromagnetic component 1 snaps into the snap-fit ​​engagement structure 15 on the auxiliary limiting component 8, it is equivalent to the auxiliary limiting component 8 fixing the orientation of the electromagnetic component 1. This can prevent interference between the external air pipe and the lead wire of the coil of the electromagnetic component 1, and at the same time specify the orientation of the electromagnetic component 1, so that the manufactured products are standardized.

[0034] See also Figure 1 and Figure 2As shown, the valve core assembly 2 also includes an elastic component 23, which is sandwiched between the electromagnetic assembly 1 and the valve core 21. When the electromagnetic assembly 1 is energized, it attracts the valve core 21, causing the valve core 21 to compress the elastic component 23. The valve core 21 opens the exhaust port 7, and gas is discharged from the intake channel 4 through the exhaust channel 5, thus venting the solenoid valve. When the electromagnetic assembly 1 is de-energized, the magnetic attraction of the electromagnetic assembly 1 to the valve core 21 disappears, and the valve core 21 closes the exhaust port 7 under the action of the elastic force of the elastic component 23 and its own gravity, thus ending the venting process of the solenoid valve. It is understood that the valve core 21 is made of a magnetically conductive metal material. Preferably, the elastic component 23 is a spring.

[0035] This utility model also provides an electronically controlled air suspension system, including the aforementioned solenoid valve.

[0036] This utility model also provides a vehicle including the aforementioned electronically controlled air suspension system.

[0038] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above are only preferred embodiments of this utility model.
