Description

Technical Field

[0001] The invention relates to the technical field of automobile air suspension, and in particular to a precision air pressure control valve for automobile air suspension. Background Art

[0002] Automobile air suspension system refers to a suspension system that uses air springs as elastic elements and adjusts the air pressure in the air springs through air compressors, air tanks, precision air pressure control valves and other components to adjust the vehicle body height, suspension stiffness and damping. The precision air pressure control valve is used to adjust the air pressure in the air springs to achieve precise control of 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, shortening the connecting pipe between the valve and the air spring, allowing the valve to control the air pressure in the air spring more quickly and accurately, thereby improving the response speed and adjustment accuracy of the air suspension system.

[0004] Then, when the car is driving, it is easy for water or impurities on the road to attach to the precision air pressure control valve, which makes the precision air pressure control valve susceptible to erosion, thereby affecting the accuracy of the air pressure control valve in controlling the air pressure in the air spring.

[0005] Based on this, the present invention designs a precise air pressure control valve for automobile air suspension to solve the above problems. Summary of the invention

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

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: A precision air pressure control valve for automobile air suspension includes an electromagnetic control valve and a protective mechanism, wherein the protective mechanism includes a transparent frame arranged on the surface of the electromagnetic control valve, a pressure plate is clamped on the top of the transparent frame, a plurality of connecting frames are slidably connected to the inner wall of the transparent frame, a first spring is fixedly connected to the upper end of the surface of the connecting frame, the other end of the first spring is fixedly connected to the inner wall of the transparent frame, the upper end of the surface of the connecting frame is clamped to the lower end of the surface of the pressure plate, bolts are arranged inside the transparent frame, and a sealing ring is fixedly connected to the inner wall of the pressure plate.

[0008] Furthermore, a limiting ring is rotatably connected to the upper end of the surface of the bolt, and the surface of the limiting ring is clamped to the lower end of the inner wall of the connecting frame.

[0009] Furthermore, a plurality of arc blocks are slidably connected to the inner wall of the pressure plate, and the surface of the arc blocks contacts the surface of the sealing ring.

[0010] Furthermore, a second spring is fixedly connected to the surface of the arc block, and the other end of the second spring is fixedly connected to the inner wall of the pressure plate.

[0011] Furthermore, a rubber plate is fixedly connected to the bottom of the pressing plate.

[0012] Furthermore, two fixing blocks are slidably connected to the inner wall of the transparent frame, and the surfaces of the fixing blocks are in contact with the surface of the electromagnetic control valve.

[0013] 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.

[0014] Furthermore, two soft pads are fixedly connected to the bottom of the rubber plate, and the surfaces of the soft pads are in contact with the surface of the fixing block. Beneficial Effects

[0015] 1. The electromagnetic control valve is enclosed by the transparent frame and the pressure plate. Compared with the existing automobile, which is easy to make water or impurities on the road attached to the electromagnetic control valve during driving, this method blocks sewage or impurities from being attached to the electromagnetic control valve, ensures the relative cleanliness of the electromagnetic control valve, and ensures that the electromagnetic control valve controls the air pressure in the air spring accurately. The pressure plate is quickly installed in the transparent frame through the first spring and the connecting frame. The air pipe on the electromagnetic control valve is in close contact with the pressure plate through the sealing ring, thereby preventing impurities from entering the transparent frame through the gap between the air pipe and the pressure plate; 2. The bolts and the limiting ring are used to lock the connecting frame, ensuring that the connecting frame is stably connected to the pressure plate, thereby ensuring that the pressure plate is stably installed in the transparent frame. The second spring and the arc block are used to resist the sealing ring, ensuring that the sealing ring is stably fitted to the air pipe on the electromagnetic control valve.

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0020] The present invention will be further described below in conjunction with the embodiments.

[0021] In some embodiments, please refer to the attached instructions. Figure 1-4 A precision air pressure control valve for automobile air suspension includes an electromagnetic control valve 1 and a protective mechanism 2. The protective mechanism 2 includes a transparent frame 21 arranged on the surface of the electromagnetic control valve 1. A pressure plate 22 is clamped on the top of the transparent frame 21. A plurality of 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 end of the 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 end of the surface of the connecting frame 24 is clamped to the lower end of the surface of the pressure plate 22. Bolts 23 are arranged inside the transparent frame 21. A sealing ring 28 is fixedly connected to the inner wall of the pressure plate 22.

[0022] The electromagnetic control valve 1 is composed of a pressure sensor, a position sensor, a valve body, a valve core, a driving device and a sealing member. The air pipe on the electromagnetic control valve 1 is connected to the air spring and the air storage tank respectively.

[0023] When the air spring on the car's air suspension needs to be controlled in terms of air pressure and height, the solenoid control valve 1 adjusts the amount of compressed air entering or exhausting the air spring by receiving the signal from the electronic control unit, thereby accurately controlling the air pressure and height of the air spring. When the vehicle's driving conditions change, such as acceleration, deceleration, turning, or passing through uneven roads, the ECU will quickly calculate and issue instructions to the solenoid control valve 1 based on the information collected by the sensor, so that the solenoid control valve 1 opens or closes to a certain degree, thereby achieving precise regulation of the air spring pressure.

[0024] In the embodiment of the present invention, 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 extended out of the sealing ring 28, and 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 can be quickly installed in the transparent frame 21, and the transparent frame 21 is installed to a suitable position at the bottom of the car through the bolts 23.

[0025] In the embodiment of the present invention, the electromagnetic control valve 1 is enclosed by the transparent frame 21 and the pressure plate 22, thereby preventing sewage or impurities from being attached to the electromagnetic control valve 1, ensuring the relative cleanliness of the electromagnetic control valve 1, and ensuring that the electromagnetic control valve 1 accurately controls the air pressure in the air spring. The pressure plate 22 is quickly installed in the transparent frame 21 through the first spring 25 and the connecting frame 24, and the air pipe on the electromagnetic control valve 1 is in close contact with the pressure plate 22 through the sealing ring 28, thereby preventing impurities from entering the transparent frame 21 through the gap between the air pipe and the pressure plate 22.

[0026] In some embodiments, Figure 4 As shown, as a preferred embodiment of the present invention, the upper end of the surface of the bolt 23 is rotatably connected with a limiting ring 26, the surface of the limiting ring 26 is clamped on the lower end of the inner wall of the connecting frame 24, and the inner wall of the pressure plate 22 is slidably connected with a plurality of arc blocks 29, the surface of the arc blocks 29 contacts the surface of the sealing ring 28, and the surface of the arc blocks 29 is fixedly connected with a second spring 210, and the other end of the second spring 210 is fixedly connected to the inner wall of the pressure plate 22.

[0027] In the embodiment of the present invention, the bolt 23 is threadedly installed in the car, which causes the limiting ring 26 to be clamped into the connecting frame 24, so that the connecting frame 24 is stably clamped in the pressure plate 22, and the elastic force of the second spring 210 pushes the arc block 29 to move, so that the arc block 29 contacts the surface of the sealing ring 28.

[0028] In the embodiment of the present invention, the bolt 23 and the limiting ring 26 are used to lock the connecting frame 24, thereby ensuring that the connecting frame 24 is stably clamped in the pressure plate 22, thereby ensuring that the pressure plate 22 is stably installed in the transparent frame 21, and the second spring 210 and the arc block 29 are used to resist the sealing ring 28, thereby ensuring that the sealing ring 28 is stably fitted to the air pipe on the electromagnetic control valve 1.

[0029] In some embodiments, Figure 2As shown, as a preferred embodiment of the present invention, the bottom of the pressure plate 22 is fixedly connected with a rubber plate 213, the inner wall of the transparent frame 21 is slidably connected with two fixed blocks 212, the surface of the fixed block 212 contacts the surface of the electromagnetic control valve 1, the surface of the fixed block 212 is fixedly connected with a third spring 27, the other end of the third spring 27 is fixedly connected to the inner wall of the transparent frame 21, and the bottom of the rubber plate 213 is fixedly connected with two soft pads 211, the surface of the soft pads 211 contacts the surface of the fixed block 212. The air pipe on the electromagnetic control valve 1 passes through and extends out of the inner wall of the rubber plate 213.

[0030] In the embodiment of the present invention, 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.

[0031] In the embodiment of the present invention, the electromagnetic control valve 1 is stably clamped by the third spring 27 , the fixing block 212 , the rubber plate 213 and the cushion 211 , thereby ensuring the stability of the electromagnetic control valve 1 inside the transparent frame 21 .

[0032] 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 in the above description are all relatively mature devices in the 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 a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.
