Description

Technical Field

[0001] This utility model relates to the field of automotive air suspension technology, specifically to a precision air pressure control valve for automotive air suspension. Background Technology

[0002] An automotive air suspension system uses air springs as elastic elements. It adjusts the air pressure within the air springs via components such as an air compressor, air tank, and precision air pressure control valves, thereby regulating vehicle height, suspension stiffness, and damping. The precision air pressure control valves are used to regulate the air pressure within the air springs, thus achieving precise control over suspension height and stiffness.

[0003] Existing precision air pressure control valves are usually installed at the bottom of the vehicle body near the air springs of the four wheels. This shortens the connecting pipes between the valve and the air springs, allowing the valve to control the air pressure in the air springs more quickly and accurately, thus improving the response speed and adjustment accuracy of the air suspension system.

[0004] Then, when the car is in motion, water or impurities from the road surface can easily adhere to the precision air pressure control valve, which can make the valve susceptible to corrosion and thus affect the accuracy of the air pressure control valve in controlling the air spring.

[0005] Based on this, this utility model designs a precision air pressure control valve for automotive air suspension to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a precision air pressure control valve for automobile air suspension.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A precision air pressure control valve for automotive air suspension includes an electromagnetic control valve and a protective mechanism. The protective mechanism includes a transparent frame disposed on the surface of the electromagnetic control valve. A pressure plate is snapped onto the top of the transparent frame. Several connecting frames are slidably connected to the inner wall of the transparent frame. A first spring is fixedly connected to the upper surface of each connecting frame. The other end of the first spring is fixedly connected to the inner wall of the transparent frame. The upper surface of each connecting frame is snapped onto the lower surface of the pressure plate. Bolts are provided inside the transparent frame. A sealing ring is fixedly connected to the inner wall of the pressure plate.

[0009] Furthermore, a limiting ring is rotatably connected to the upper surface of the bolt, and the surface of the limiting ring is engaged with the lower end of the inner wall of the connecting frame.

[0010] Furthermore, the inner wall of the pressure plate is slidably connected with several arc-shaped blocks, the surfaces of which are in contact with the surfaces of the sealing rings.

[0011] Furthermore, a second spring is fixedly connected to the surface of the arc-shaped block, and the other end of the second spring is fixedly connected to the inner wall of the pressure plate.

[0012] Furthermore, a rubber plate is fixedly connected to the bottom of the pressure plate.

[0013] Furthermore, the inner wall of the transparent frame is slidably connected with two fixing blocks, the surfaces of which are in contact with the surface of the electromagnetic control valve.

[0014] Furthermore, a third spring is fixedly connected to the surface of the fixing block, and the other end of the third spring is fixedly connected to the inner wall of the transparent frame.

[0015] Furthermore, two soft pads are fixedly connected to the bottom of the rubber plate, and the surface of the soft pads contacts the surface of the fixing block. Beneficial effects

[0016] 1. The transparent frame and pressure plate protect the electromagnetic control valve. Compared to existing vehicles, where water or impurities from the road surface can easily adhere to the electromagnetic control valve while driving, this method prevents sewage or impurities from adhering to the electromagnetic control valve, ensuring its relative cleanliness and accurate control of the air pressure in the air spring. The pressure plate can be quickly installed in the transparent frame through the first spring and connecting frame. The sealing ring ensures that the air pipe on the electromagnetic control valve is in close contact with the pressure plate, thereby preventing impurities from entering the transparent frame through the gap between the air pipe and the pressure plate.

[0017] 2. The bolts and limiting rings lock the connecting frame, ensuring that the connecting frame is stably clamped in the pressure plate, which in turn ensures that the pressure plate is stably installed in the transparent frame. The second spring and the arc block achieve contact with the sealing ring, ensuring that the sealing ring is stably attached to the air pipe on the electromagnetic control valve.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4 A precision air pressure control valve for automotive air suspension includes an electromagnetic control valve 1 and a protective mechanism 2. The protective mechanism 2 includes a transparent frame 21 disposed on the surface of the electromagnetic control valve 1. A pressure plate 22 is snapped onto the top of the transparent frame 21. Several connecting frames 24 are slidably connected to the inner wall of the transparent frame 21. A first spring 25 is fixedly connected to the upper surface of the connecting frame 24. The other end of the first spring 25 is fixedly connected to the inner wall of the transparent frame 21. The upper surface of the connecting frame 24 is snapped onto the lower surface of the pressure plate 22. Bolts 23 are provided inside the transparent frame 21. A sealing ring 28 is fixedly connected to the inner wall of the pressure plate 22.

[0028] The electromagnetic control valve 1 consists of a pressure sensor, a position sensor, a valve body, a valve core, a drive device, and seals. The air pipes on the electromagnetic control valve 1 are connected to the air spring and the air tank, respectively.

[0029] When it is necessary to control the air pressure and height of the air springs in a car's air suspension, the solenoid control valve 1 receives signals from the electronic control unit (ECU) and adjusts the amount of compressed air entering or exiting the air springs, thereby precisely controlling the air spring pressure and height. When the vehicle's driving conditions change, such as acceleration, deceleration, turning, or driving over uneven roads, the ECU quickly calculates based on information collected by sensors and sends a command to the solenoid control valve 1, causing it to open or close to a certain extent, thus achieving precise adjustment of the air spring pressure.

[0030] In this embodiment of the utility model, the electromagnetic control valve 1 is installed inside the transparent frame 21. The air pipe on the electromagnetic control valve 1 is passed through and extends out of the sealing ring 28, so that the pressure plate 22 can be snapped into the transparent frame 21. At this time, the elastic force of the first spring 25 pushes the connecting frame 24 to move and snap into the pressure plate 22, so that the pressure plate 22 is quickly installed in the transparent frame 21. The transparent frame 21 is installed at a suitable position on the bottom of the car by bolts 23.

[0031] In this embodiment of the utility model, the transparent frame 21 and the pressure plate 22 are used to protect the electromagnetic control valve 1, thereby preventing sewage or impurities from adhering to the electromagnetic control valve 1, ensuring the relative cleanliness of the electromagnetic control valve 1, and ensuring the accuracy of the air pressure in the air spring controlled by the electromagnetic control valve 1. The first spring 25 and the connecting frame 24 enable the pressure plate 22 to be quickly installed in the transparent frame 21. The sealing ring 28 ensures that the air pipe on the electromagnetic control valve 1 is in close contact with the pressure plate 22, thereby preventing impurities from entering the transparent frame 21 through the gap between the air pipe and the pressure plate 22.

[0032] In some embodiments, such as Figure 4 As shown, in a preferred embodiment of the present invention, a limiting ring 26 is rotatably connected to the upper surface of the bolt 23. The surface of the limiting ring 26 is engaged with the lower end of the inner wall of the connecting frame 24. Several arc-shaped blocks 29 are slidably connected to the inner wall of the pressure plate 22. The surface of the arc-shaped blocks 29 contacts the surface of the sealing ring 28. A second spring 210 is fixedly connected to the surface of the arc-shaped blocks 29. The other end of the second spring 210 is fixedly connected to the inner wall of the pressure plate 22.

[0033] In this embodiment of the utility model, the bolt 23 is threaded inside the car, which causes the limiting ring 26 to be engaged in the connecting frame 24, so that the connecting frame 24 is stably engaged in the pressure plate 22. The elastic force of the second spring 210 pushes the arc block 29 to move, so that the arc block 29 abuts against the surface of the sealing ring 28.

[0034] In this embodiment of the utility model, the bolt 23 and the limiting ring 26 are used to lock the connecting frame 24, ensuring that the connecting frame 24 is stably engaged in the pressure plate 22, thereby ensuring that the pressure plate 22 is stably installed in the transparent frame 21. The second spring 210 and the arc block 29 are used to abut against the sealing ring 28, ensuring that the sealing ring 28 is stably attached to the air pipe on the electromagnetic control valve 1.

[0035] In some embodiments, such as Figure 2 As shown, in a preferred embodiment of this utility model, a rubber plate 213 is fixedly connected to the bottom of the pressure plate 22, and two fixing blocks 212 are slidably connected to the inner wall of the transparent frame 21. The surface of the fixing blocks 212 contacts the surface of the electromagnetic control valve 1, and a third spring 27 is fixedly connected to the surface of the fixing blocks 212. The other end of the third spring 27 is fixedly connected to the inner wall of the transparent frame 21, and two soft pads 211 are fixedly connected to the bottom of the rubber plate 213. The surface of the soft pads 211 contacts the surface of the fixing blocks 212. The air pipe on the electromagnetic control valve 1 passes through and extends out of the inner wall of the rubber plate 213.

[0036] In this embodiment of the utility model, the elastic force of the third spring 27 pushes the fixed block 212 to move, so that the fixed block 212 abuts against the electromagnetic control valve 1. At this time, the pressure plate 22 is snapped into the transparent frame 21, so that the rubber plate 213 abuts against the top of the electromagnetic control valve 1, and the surface of the soft pad 211 abuts against the fixed block 212.

[0037] In this embodiment of the utility model, the third spring 27, the fixing block 212, the rubber plate 213 and the soft pad 211 are used to achieve stable clamping of the electromagnetic control valve 1, ensuring the stability of the electromagnetic control valve 1 inside the transparent frame 21.

[0038] It should be noted that the electromagnetic control valve 1, transparent frame 21, pressure plate 22, bolt 23, first spring 25, second spring 210, third spring 27 and sealing ring 28 mentioned above are all components with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the electromagnetic control valve 1 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
