Description

Technical Field

[0001] The utility model relates to the field of air springs, and particularly to an air spring integrated control system. Background Art

[0002] With the increasing requirements for vehicle riding comfort, the comfort performance of vehicles can now be adjusted in two aspects: one is to change the original coil spring shock absorption to air spring shock absorption; the other is to change the fixed damping shock absorber to a variable damping shock absorber, and timely adjust the damping force value of the shock absorber when the road bump intensity changes, so as to reduce the vibration transmitted to the vehicle body.

[0003] The current vehicle air shock absorbers mainly consist of air bags, height sensors, solenoid valves, air pumps, ECU control systems, wire harnesses, air circuits, etc. At the same time, complex algorithms and software programs are required to control each component to achieve the adjustment of the vehicle body height gear and the self-suspension function. The height sensor senses the change in the vehicle body height and feeds it back to the ECU. The ECU controls the opening and closing of the solenoid valve to inflate and exhaust the air bag, so as to control the change in the vehicle body height and the suspension function, and improve the comfort performance of the vehicle.

[0004] There are mainly two ways to adjust the variable damping: one is to change the viscosity of the liquid in the damper to change the damping force value; the other is to change the diameter of the valve plate to change the flow velocity of the liquid inside, so as to change the damping force value. This form of control method mainly detects the road bumps through sensors or cameras and feeds them back to the ECU. The ECU controls the solenoid valve to act to change the diameter of the valve plate to control the damping force value. At present, the second method is mainly used in large quantities and is relatively mature, and there are still some technical problems to be improved in the first type of variable damping shock absorber.

[0005] The main factors restricting the popularization of air shock absorption and variable damping are high price, many faults, difficult maintenance, complex control algorithms, etc. And due to the response time of the solenoid valve and the ECU, there is a certain degree of reaction lag, which has a certain impact on the comfort performance.

In the description of the embodiments of the present invention, the meaning of "a plurality" is two or more unless otherwise specifically defined.

[0084] According to one aspect of the present invention, Figure 1 A schematic structural diagram of an air spring integrated control system is shown, Figure 2 A schematic structural diagram of an air spring integrated control unit is shown, Figure 3 An exploded view of the air spring integrated control unit is shown, as Figure 1 、 Figure 2 and Figure 3 shown. An air spring integrated control system is designed. The air spring integrated control system includes an air spring integrated control unit 100, an air pipe 200, a variable damping drive cylinder 500, an air spring 600, and an adjustable damping shock absorber 700;

[0085] Furthermore, the air spring integrated control unit 100 includes a swing rod 101, a nut 102, an airbag interface end 103, an exhaust muffler 104, a gas source interface 105, a variable damping interface end 106, a housing 107, a mandrel 108, a valve plate B 109, a spring 110, a screw 111, a valve plate A 112, a central hole 113, a sealing ring 114, a connecting plate 115, a forward and reverse motor 116, and a dust cover 117. The forward and reverse motor 116 has a self-locking function and controls the motor to rotate forward and reverse through a forward and reverse switch;

[0086] Furthermore, the housing 107 is provided with an inner card slot 107-5, an outer card slot 107-1, an airbag channel 107-2, an exhaust channel 107-3, and a variable damping channel 107-4.

[0087] It can be seen that the air spring system requires particularly few components, especially electronic components, has a simple structure, a low cost, and a lower probability of subsequent failures, and less maintenance cost.

[0088] In some embodiments of the present invention, Figure 4 shows a front schematic view of the valve plate B, Figure 5 shows a back schematic view of the valve plate B; as shown in the figure, an air spring integrated control system is designed. The top diameter of the valve plate B 109 is smaller than the bottom diameter. The top of the valve plate B 109 is an irregular cylinder, and a through hole is provided in the center of the valve plate B 109;

[0089] Specifically, one end of the valve plate B 109 is provided with an airbag interface 109-1, an airbag groove 109-2, an exhaust interface 109-3, a variable damping interface 109-4, and a variable damping groove 109-5. The airbag interface 109-1 is communicated with the airbag interface end 103 through the airbag channel 107-2. The exhaust interface 109-3 is communicated with the exhaust muffler 104 through the exhaust channel 107-3. The variable damping interface 109-4 is communicated with the variable damping interface end 106 through the variable damping channel 107-4.

[0090] It can be seen that multiple structures are provided inside the valve plate B to connect various components, eliminating the need to separately connect other components for communication. This not only reduces the assembly cost but also reduces problems such as air leakage and improper fitting caused by the assembly of multiple components.

[0091] In some embodiments of the present invention, Figure 6 shows a back schematic view of the valve plate A, as Figure 2 、 Figure 3 and Figure 6As shown, an integrated control system for an air spring is designed. The connecting plate 115 is fixedly and rigidly connected to the forward and reverse motor 116 through the screw 111, and the connecting plate 115 is fixedly and rigidly connected to the valve plate A 112 through the screw 111.

[0092] It can be seen that the rotation direction of the valve plate A is the same as that of the forward and reverse motor, and the rotation direction of the valve plate A is controlled by the forward and reverse rotation motor.

[0093] In some embodiments of the present invention, Figure 7 The front view of the valve plate A is shown. As Figure 6 and Figure 7 shown, an integrated control system for an air spring is designed. The valve plate A 112 is provided with an air source groove 112-1 and an exhaust groove 112-2. A cylindrical groove is provided at the other end of the valve plate A 112. A through hole is provided at the center of the valve plate A 112. A part of the outer circle of the valve plate A 112 is a regular cylinder and a part is an irregular cylinder.

[0094] It can be seen that the irregular cylinder part of the valve plate A can be matched with the card slot on the connecting plate, so as to fix the two together.

[0095] In some embodiments of the present invention, Figure 8 The front view of the housing 107 is shown. Figure 9 The back view of the housing 107 is shown. As Figure 8 and Figure 9 shown, an integrated control system for an air spring is designed. The housing 107 is fixedly and rigidly connected to the swing rod 101 through the outer card slot 107-1, and the housing 107 is fixedly and rigidly connected to the irregular cylinder of the valve plate B 109 through the inner card slot 107-5.

[0096] It can be seen that the valve plate B is indirectly fixed to the swing rod, and the movement track of the valve plate B is related to the movement track of the swing rod.

[0097] In some embodiments of the present invention, Figure 10 The external view of the mandrel is shown. Figure 11 The sectional view of the mandrel along the center line is shown. Figure 12 The sectional view of the integrated control unit of the air spring in the XZ direction is shown. Figure 13 The sectional view of the integrated control unit of the air spring in the YZ direction is shown. As Figure 10 、 Figure 11 、 Figure 12 and Figure 13As shown, an integrated control system for an air spring is designed. One end of the mandrel 108 has a diameter larger than the overall diameter. The region with a smaller diameter of the mandrel 108 is a hollow structure 108-2. An annular groove 108-1 and a vent hole 108-4 are provided near the region with a larger diameter of the mandrel 108. The mandrel 108 is provided with a plurality of seal ring groove 108-3 structures;

[0098] Specifically, the mandrel 108 adaptively connects the valve plate B 109, the valve plate A 112, the housing 107, and the swing rod 101 through the nut 102.

[0099] It can be seen that the mandrel is similar to a rotating shaft, fixing the valve plate B 109, the valve plate A, the housing, and the swing rod together. The valve plate B and the valve plate A can rotate around the mandrel.

[0100] In some embodiments of the present invention, as Figure 11 As shown, an integrated control system for an air spring is designed. The vent holes 108-4 respectively pass through the annular groove 108-1 and the hollow structure 108-2 of the mandrel 108. The hollow structure 108-2 is connected to the gas source interface 105.

[0101] In some embodiments of the present invention, as Figure 1 As shown, an integrated control system for an air spring is designed. The air spring integrated control unit 100 is adaptively connected to the upper body 400 through the swing rod 101. The air spring integrated control unit 100 is fixedly connected to the lower swing arm 300 through the forward and reverse motor 116.

[0102] It can be seen that the rotation directions of the valve plate B and the valve plate A are indirectly related to the lower swing arm and the upper body of the suspension.

[0103] In some embodiments of the present invention, as Figure 1 As shown, an integrated control system for an air spring is designed. The air spring integrated control unit 100 is fixedly connected to the variable damping cylinder and the adjustable damping shock absorber 700 through the air pipe 200.

[0104] Figure 14 Shows a schematic diagram of the positional relationship of each groove and interface of the valve plate A and the valve plate B in the balanced position state of the air spring integrated control unit;

[0105] Figure 15 Shows a schematic diagram of the positional relationship of each groove and interface of the valve plate A and the valve plate B in the inflated state of the air spring integrated control unit;

[0106] Figure 16It shows a schematic diagram of the positional relationship of each groove and interface of valve plate A and valve plate B in the exhaust state of the air spring integrated control unit;

[0107] The specific working principle of this air spring integrated control system is as follows:

[0108] 1. Active adjustment: As shown in Figure 14 , Figure 15 and Figure 16 , when the height of the upper body 400 needs to be increased, the forward and reverse motor 116 rotates counterclockwise by a certain angle, driving the valve plate A112 to rotate synchronously, generating a relative rotational angular displacement with the valve plate B109. The air source groove 112-1 on the valve plate A112 communicates with the airbag groove 109-2 on the valve plate B109. The gas in the air source interface 105 successively passes through the air source groove 112-1, the airbag groove 109-2, and the airbag interface 109-1 and enters the air spring 600. The internal air pressure of the air spring increases, pushing the height of the upper body 400 to rise. The end of the swing rod 101 connected to the upper body 400 also moves upward, driving the valve plate B109 to rotate counterclockwise. When the valve plate B109 rotates to the equilibrium position, the gas in the air source interface 105 no longer enters the air spring 600, and the height adjustment of the upper body 400 is completed;

[0109] Conversely, when the height of the upper body 400 needs to be decreased, the forward and reverse motor 116 rotates clockwise by a certain angle, driving the valve plate A112 to rotate synchronously, generating a relative rotational angular displacement with the valve plate B109. The airbag groove 109-2 on the valve plate A112 communicates with the exhaust groove 112-2 on the valve plate B109. The gas in the air spring 600 is discharged through the exhaust interface 109-3. The vehicle body drops under the action of gravity, the end of the swing rod 101 drops, driving the valve plate B109 to rotate clockwise to the equilibrium position, and the gas in the air spring 600 no longer discharges, realizing the height decrease adjustment of the vehicle body.

[0110] 2. Suspension adjustment: As shown in Figure 14 , Figure 15 and Figure 16 , suspension adjustment is that the vehicle automatically inflates and exhausts according to the road conditions and makes autonomous adjustment. The forward and reverse motor 116 maintains a self-locking state, the valve plate A112 remains stationary, and the valve plate B109 rotates clockwise or counterclockwise driven by the swing rod 101 to inflate or exhaust the airbag, realizing the active suspension function.

[0111] When the vehicle jolts while driving on an uneven road surface, when the wheel jumps up, the distance between the swing arm and the vehicle body decreases, driving the swing rod 101 to rotate clockwise, driving the valve plate B109 to rotate, and the air source interface 105 is connected to the air spring 600 for inflation, and the internal air pressure of the air spring 600 increases;

[0112] When the wheel bounces downward, the distance between the swing arm and the vehicle body increases, the swing rod 101 rotates counterclockwise, the air spring 600 is connected to the exhaust hole for exhaust, and the air pressure inside the air spring 600 decreases; the air pressure inside the air spring 600 increases or decreases mainly to forcibly maintain the vehicle body in a balanced state as much as possible, prevent large-angle rollover, and provide a more comfortable riding experience for passengers.

[0113] 3. Variable damping adjustment: As Figure 14 , Figure 15 and Figure 16 shown, when the vehicle is driving on a flat road without bumps, the damping force value of the shock absorber is in the softest state at this time, and the passengers are in the most comfortable riding state; when the road conditions deteriorate and the vehicle jolts violently, the wheel will bounce upward or downward greatly, driving the swing rod 101 to drive the valve plate B109 to also rotate at a large angle. At this time, the air source interface 105 is immediately connected to the variable damping interface 109-4, and the gas in the air source interface 105 enters the variable damping drive cylinder 500. Since the internal volume of the variable damping drive cylinder 500 is small, the reaction speed of the internal rod of the variable damping drive cylinder is extremely fast, and it extends instantly, pushing the adjustable damping shock absorber 700 to adjust the lever to rotate, and adjusting the damping force value to the maximum, which can effectively prevent the vehicle body from shaking violently repeatedly.

[0114] When the vehicle resumes stable operation, due to the time-delay function of the variable damping drive cylinder 500, the damping force value is slowly restored to the softest state, realizing the adaptive adjustment of the damping force value. Since the variable damping groove 109-5 is annular, whether the wheel bounces upward or downward, the instantaneous reaction of the variable damping drive cylinder 500 can be realized. At the same time, due to the time-delay function of the exhaust of the variable damping drive cylinder 500, the damping force value on the bumpy road can be prevented from changing repeatedly, and it can always be maintained in the state of the maximum damping force value.

[0115] In summary, adopting this air spring integrated control system can completely replace the height sensor, solenoid valve, ECU, and damping adjustment mechanism of the original air shock absorption system. Moreover, the structure is simple, the operation is stable, and it does not require complex software programs such as algorithms. All actions respond according to the changes of the vehicle body at any time, omitting the action time of each step such as the sensor signal feedback of the original structure, the ECU issuing instructions, and the solenoid valve responding. The control is more accurate and the comfort is better; and because fewer components are used, especially electronic components, the occurrence of failure rates can be greatly reduced, the maintenance cost can be reduced, and at the same time, the price of the air shock absorption can be greatly reduced, and the later maintenance and repair costs can be reduced.

[0116] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
