Description
Technical fields:
[0001] This invention relates to an inflatable, spring-driven, hydraulic, and power-coupled shock absorber and its control method. Background technology:
[0002] Pneumatic shock absorbers are a type of automotive shock absorber that has been promoted in the market in recent years. While they are highly sensitive, their damping force is too small; they will overload and fail under large vibrations, rendering them ineffective. During damping, pneumatic shock absorbers generate heat, causing rapid aging of the pneumatic piston seals, leading to air leakage. Hydraulic shock absorbers offer strong damping force but slow damping speed. Suspension-type hydraulic shock absorbers have a smaller damping amplitude and slower damping speed, making them suitable for lower frequency vibrations. They are suitable for applications like heavy tanks, but not for automobiles. Suspension spring shock absorbers are the traditional type of automotive shock absorber. They are not adjustable, do not absorb energy, and can even resonate, increasing vibration. Historically, automobiles have primarily used suspension spring shock absorbers. Summary of the Invention:

[0005] A control method for an air-inflated, spring-driven, hydraulically coupled, and generator-coupled shock absorber. The air compressor is started, and compressed air from the compressor enters the air tank through a one-way valve. When a pressure relay on top of the air tank detects that the air pressure inside the tank is higher than a set high pressure value, the computer controller stops supplying power to the air compressor, and the one-way valve prevents compressed air from leaking out of the air tank. When the pressure relay on top of the air tank detects that the air pressure inside the tank has dropped to a set low pressure value, the computer controller restarts the air compressor. Based on data from the tension spring distance sensors and in the air-inflated, spring-driven, hydraulically coupled, and generator-coupled automotive shock absorber mode, the computer controller energizes and opens two four-way solenoid intake valves. Compressed air from the air tank enters the two compressed air and hydraulic oil bladders through these two four-way valves. The computer controller also energizes and opens two oil tank solenoid intake valves, inflating the two oil tanks with compressed air. Hydraulic oil from the bottom of the two reservoirs enters the lower part of the two compressed air and hydraulic bladders after being energized and opened by the electromagnetic oil outlet valves of the two reservoirs and two flow sensors. The computer controller uses data from the two flow sensors to control the opening time of the electromagnetic air inlet valves of the two reservoirs, thereby controlling the hydraulic oil level in the lower part of the two compressed air and hydraulic bladders. This pushes the steel plates on the two compressed air and hydraulic bladders upwards, lifting the car chassis through the suspension and ensuring that the two tension spring distance sensors provide the same data, keeping the two wheels on the same plane. On a bumpy, rough road, if a car wheel falls into a pothole and then rises out, the up-and-down movement of the car chassis causes the permanent magnet tube to move up and down within the coil tube, generating electricity and providing damping. On the same bumpy, rough road, if a car wheel falls into a pothole and then rises out, the several layers of paddle damping plates mounted on the lower part of the shaft steel cable move up and down within the hydraulic oil in the lower part of the compressed air and hydraulic bladders, providing damping. On a bumpy, rough road, a car's wheel falls into a pothole. As the wheel moves downwards, the pressure of the compressed air in the upper part of the hydraulic bladder decreases, causing the serrated spring tube of the bladder to extend. This decrease in pressure on the hydraulic oil in the lower part of the bladder, due to the reduced pressure of the compressed air in the upper part, forces some hydraulic oil from the corresponding reservoir into the lower part of the bladder via two energized solenoid valves and a flow sensor. As the car chassis moves downwards, the wheel emerges from the pothole. The compressed air in the upper part of the bladder is further compressed, compressing the serrated spring tube. This increased pressure forces some hydraulic oil from the lower part of the bladder into the corresponding reservoir via the flow sensor and the energized solenoid valves, providing a damping effect.Based on data from the tension spring distance sensors and in the air, spring, and generator coupled vehicle damping mode, the computer controller energizes and opens two four-way electromagnetic air intakes. Compressed air from the air tanks passes through the two four-way electromagnetic intake valves and enters the upper part of the two compressed air and hydraulic bladders. The computer controller also energizes and opens the two electromagnetic exhaust valves and oil outlet valves of the two oil tanks. Compressed air from the upper part of the two compressed air and hydraulic bladders forces hydraulic oil from the lower part of the two oil tanks into the two oil tanks through two flow sensors and the energized electromagnetic oil outlet valves. When the flow sensor data is zero, the electromagnetic oil outlet valves of the two oil tanks are de-energized and closed, followed by the de-energization and closure of the electromagnetic exhaust valves. The compressed air from the upper part of the two compressed air and hydraulic bladders pushes the upper steel plates of the two compressed air and hydraulic bladders upwards, lifting the vehicle chassis through the suspension and ensuring that the two tension spring distance sensors provide the same data, keeping all four wheels on a single plane. On a bumpy, rough road, a car wheel falls into a pothole and then emerges. The up-and-down movement of the car chassis causes the permanent magnet tube to move up and down within the coil tube, generating electricity and providing a damping effect. As the car wheel moves downwards, the pressure of the compressed air in the upper part of the hydraulic bladder decreases, causing the serrated spring tube of the hydraulic bladder to extend. As the car chassis moves downwards and the wheel emerges from the pothole, the compressed air in the upper part of the hydraulic bladder is further compressed, further compressing the serrated spring tube and providing damping. Based on data from the tension spring distance sensors and in the spring, hydraulic, and power generation coupled car damping mode, the computer controller energizes and opens two four-way solenoid exhaust valves and two solenoid intake valves for the oil tanks. Compressed air from the oil tanks is then used to inflate the two oil tanks. Hydraulic oil from the bottom of the reservoir passes through two electromagnetic outlet valves and two flow sensors, opening to enter two compressed air and hydraulic oil bladders. Compressed air from the upper parts of these bladders is then expelled through two four-way electromagnetic exhaust valves. Both compressed air and hydraulic oil bladder inlets are equipped with stainless steel filters and filter cloths that prevent hydraulic oil from passing through, thus preventing the hydraulic oil inside from being squeezed out. Once the compressed air in the upper parts of the two bladders is exhausted, the two four-way electromagnetic exhaust valves are de-energized and closed. The hydraulic oil in the bladders pushes the upper steel plates of the bladders upwards, lifting the vehicle chassis via the suspension and ensuring that the two tension spring distance sensors provide the same data, keeping all four wheels on a single plane. Finally, the four electromagnetic intake valves of the reservoirs are de-energized and closed.On a bumpy, rough road, a car's wheel falls into a pothole and then emerges. The up-and-down movement of the car's chassis causes four permanent magnet tubes to move up and down within a coil tube, generating electricity and providing damping. On the same bumpy, rough road, as the car's wheel falls into a pothole and emerges, several layers of paddle-shaped damping plates mounted on the lower section of the axle steel wire move up and down within the hydraulic fluid in the compressed air and hydraulic bladder, providing damping. On the same bumpy, rough road, as the car's wheel falls into a pothole and moves downwards, a portion of the hydraulic fluid in the corresponding branch reservoir passes through the energized electromagnetic outlet valve and flow sensor into the compressed air and hydraulic bladder. The serrated spring tube of the compressed air and hydraulic bladder extends. The car chassis moves downwards, and then the car wheels come out of the pit. The corresponding compressed air and the sawtooth spring tube of the hydraulic oil bladder are compressed. The corresponding compressed air and a part of the hydraulic oil inside the hydraulic oil bladder are forced into the corresponding oil tank through the flow sensor and the solenoid oil outlet valve of the oil tank that is opened by electricity, which plays a damping role.

[0010] Figure 2As shown, a pneumatic, spring-loaded, hydraulic, and generator-coupled shock absorber is described. The compressed air and hydraulic oil supply system comprises an air compressor 1, a one-way valve 5, an air tank 2, a four-way valve 3, a four-way solenoid inlet valve 6, a four-way solenoid exhaust valve 8, an oil tank 4, an oil tank solenoid inlet valve 7, and an oil tank solenoid exhaust valve 9.

The structure of the compressed air and hydraulic oil bladder 12 is as follows: Several centrally symmetrical sawtooth springs are spot-welded together to form a sawtooth spring tube using several steel wire rings. A special-shaped canvas tube is sewn onto the inner surface of the sawtooth spring tube. The upper annular steel plate is fixed to the upper end of the sawtooth spring tube by spot welding, and the lower annular steel plate is installed at the lower end of the sawtooth spring tube by spot welding.

[0011] Figure 1 and Figure 2As shown, a control method for an air-inflated, spring-driven, hydraulically coupled, and generator-driven shock absorber is described. When the air compressor 1 is started, compressed air from the air compressor 1 enters the air tank 2 through a one-way valve 5. When a pressure relay mounted on the top of the air tank 2 detects that the air pressure inside the air tank 2 is higher than a set high pressure value, the computer controller stops supplying power to the air compressor 1, and the one-way valve 5 prevents compressed air from leaking out of the air compressor 1. When the pressure relay mounted on the top of the air tank 2 detects that the air pressure inside the air tank 2 has dropped to a set low pressure value, the computer controller restarts the air compressor 1. Based on the data provided by the tension spring distance sensors 16 and in the air-inflated, spring-driven, hydraulically coupled, and generator-driven vehicle shock absorber mode, the computer controller energizes and opens two four-way solenoid intake valves 6. Compressed air from the air tank 2 enters the upper part of the two compressed air and hydraulic oil bladders 12 through the energized and opened four-way solenoid intake valves 6 and two four-way valves 3. When energized, the electromagnetic air intake valves 7 of the two oil tanks are opened, allowing compressed air from oil tank 2 to fill the two oil tanks 4. Hydraulic oil from the bottom of the two oil tanks 4 enters the electromagnetic oil outlet valves 10 and two flow sensors 11, flowing into the lower part of the two compressed air and hydraulic bladders 12. The computer controller uses data from the two flow sensors 11 to control the opening time of the electromagnetic air intake valves 7, thereby controlling the hydraulic oil level in the lower part of the two compressed air and hydraulic bladders 12. This pushes the upper steel plates of the two compressed air and hydraulic bladders 12 upwards, lifting the car chassis through the suspension and ensuring that the two tension spring distance sensors 16 provide the same data, keeping all four wheels on a single plane. On a bumpy, rough road, the car's wheels fall into potholes and then emerge. The up-and-down movement of the car chassis causes the permanent magnet tube 14 to move up and down within the coil tube 15, generating electricity and providing a damping effect. On a bumpy, rough road, a car's wheel falls into a pothole and then emerges. The several layers of paddle-shaped damping plates 13, mounted on the lower section of the axle's steel cable, move up and down within the hydraulic fluid of the compressed air and hydraulic bladder 12, providing a damping effect. As the car's wheel moves downwards, the pressure of the compressed air in the upper part of the hydraulic bladder 12 decreases, causing the serrated spring tube of the bladder to extend. This decrease in pressure on the hydraulic fluid in the lower part of the bladder reduces the pressure of the compressed air in the upper part of the bladder, and a portion of the hydraulic fluid in the corresponding reservoir 4 is forced into the lower part of the hydraulic bladder 12 through four electrically activated electromagnetic outlet valves 10 and a flow sensor 11.The car chassis moves downwards, and then the car wheels emerge from the ditch. The compressed air and the compressed air in the upper part of the hydraulic bladder 12 are further compressed. The serrated spring tube of the compressed air and hydraulic bladder 12 is compressed, and the increased pressure of the compressed air and the compressed air in the upper part of the hydraulic bladder 12 forces a portion of the hydraulic oil in the lower part of the compressed air and hydraulic bladder 12 through the flow sensor 11 and the energized and opened solenoid oil outlet valve 10 into the corresponding oil tank 4, which acts as a damping effect. According to the data given by each tension spring distance sensor 16 and in the air, spring, and generator coupled car shock absorption mode, the computer controller energizes and opens two four-way solenoid air intake valves 6. The compressed air in the air tank 2 enters the upper part of the two compressed air and hydraulic bladders 12 through the energized and opened four-way solenoid air intake valves 6 and two four-way valves 3. When energized, the electromagnetic vent valves 9 of the two oil storage tanks and the electromagnetic oil outlet valves 10 of the two oil storage tanks are opened. The compressed air from the upper part of the two compressed air and hydraulic oil bladders 12 forces the hydraulic oil from the lower part of the two compressed air and hydraulic oil bladders 12 through the two flow sensors 11 and the energized electromagnetic oil outlet valves 10 into the four oil storage tanks 4. When the data of the four branch flow sensors 10 is zero, the electromagnetic oil outlet valves 10 of the two oil storage tanks are de-energized and closed, followed by the de-energization and closure of the electromagnetic vent valves 9 of the two oil storage tanks. The compressed air from the upper part of the two compressed air and hydraulic oil bladders 12 pushes the upper steel plate of the two compressed air and hydraulic oil bladders 12 upward, lifting the chassis of the car through the suspension and ensuring that the two tension spring distance sensors 16 give the same data, keeping the four wheels on the same plane. On a bumpy, rough road, the car wheels fall into the potholes and then come out. The up-and-down movement of the car chassis causes the permanent magnet tube 14 to move up and down in the coil tube 15, causing the coil tube 15 to generate electricity, which acts as a damping effect. On a bumpy, rough road, a car wheel falls into a pothole, causing it to move downwards. This reduces the pressure of the compressed air in the upper part of the hydraulic bladder 12, causing the serrated spring tube of the bladder to extend. The car chassis moves downwards, and the wheel emerges from the pothole. The compressed air in the upper part of the hydraulic bladder 12 is further compressed, further compressing the serrated spring tube and providing damping. Based on data from the tension spring distance sensors 16 and in the spring, hydraulic, and generator-coupled car damping mode, the computer controller energizes and opens two four-way solenoid exhaust valves 8 and two oil tank solenoid intake valves 7. Compressed air from the air tank 2 then fills the two oil tanks 4 through the energized solenoid intake valves 7. The hydraulic oil coming out from the bottom of the oil storage tank 4 is energized to open the two oil storage tank solenoid outlet valves 10 and the two flow sensors 11, and then enters the two compressed air and hydraulic oil bladders 12. The compressed air in the upper part of the two compressed air and hydraulic oil bladders 12 is energized to open the two four-way solenoid exhaust valves 8 and then discharged.Both compressed air and hydraulic oil bladders 12 are equipped with stainless steel filters and filter cloths that prevent hydraulic oil from passing through, thus preventing the hydraulic oil inside the compressed air and hydraulic oil bladders 12 from being squeezed out. After the compressed air in the upper part of the two compressed air and hydraulic oil bladders 12 is exhausted, the two four-way solenoid exhaust valves 8 are de-energized and closed. The hydraulic oil in the two compressed air and hydraulic oil bladders 12 pushes the upper steel plates of the two compressed air and hydraulic oil bladders 12 upward, lifting the car chassis through the suspension and ensuring that the two tension spring distance sensors 16 give the same data, keeping the four wheels on the same plane. Then, the two oil tank solenoid intake valves 7 are de-energized and closed. On a bumpy, rough road, the car wheels fall into the potholes and then come out. The up-and-down movement of the car chassis causes the four permanent magnet tubes 14 to move up and down in the coil tubes 15, causing the coil tubes 15 to generate electricity, which acts as a damping effect. On a bumpy, rough road, a car's wheel falls into a pothole and then emerges. The several layers of paddle-shaped damping plates 13, mounted on the lower section of the axle's steel cable, move up and down within the hydraulic fluid of the compressed air and hydraulic bladder 12, providing a damping effect. As the car's wheel moves downwards, a portion of the hydraulic fluid in the corresponding branch reservoir 4 enters the compressed air and hydraulic bladder 12 via the energized solenoid valve 10 and flow sensor 11. The serrated spring tube of the compressed air and hydraulic bladder 12 extends. As the car chassis moves downwards and the wheel emerges from the pothole, the serrated spring tube of the corresponding compressed air and hydraulic bladder 12 is compressed. A portion of the hydraulic fluid inside the corresponding compressed air and hydraulic bladder 12 is forced into the corresponding reservoir 4 via the flow sensor 11 and the energized solenoid valve 10, providing a damping effect.
[0012] This invention does not use cylinders or pistons, thus preventing compressed air or hydraulic oil leakage due to piston seal wear. The compressed air and hydraulic oil bladders used in this invention function as springs and containers for holding compressed air and hydraulic oil. This invention simultaneously integrates air, spring, hydraulic, and power generation coupling functions for automotive shock absorption.
