Description

Technical Field

[0001] The present invention relates to the field of air springs, and in particular to an adaptive adjustment air spring system. Background Art

[0002] Most existing air springs inflate by directly drawing air from the outside. This open inflation method is disadvantageous in some harsh environments. It not only shortens the service life of the air spring components, but also affects the data collection of various air spring systems, indirectly affecting the performance of some functions. For example, in some humid environments, environments with corrosive gases, environments with extremely low or high temperatures, and environments with a large amount of dust or fine particles.

[0003] To address this situation, a closed air spring system has been designed. The gas inside the air spring system is self-circulating. The gas discharged from the air spring will be stored in a gas storage device, and the gas will be replenished through the gas storage device when needed. Unless necessary, no gas is required from the external environment, and the lost gas only needs to be replenished in a suitable environment regularly. Summary of the invention

[0004] In view of the above problems, the present invention is proposed to provide an adaptive adjustment air spring system that overcomes the above problems or at least partially solves the above problems.

[0005] According to one aspect of the present invention, there is provided an adaptive adjustment air spring system comprising an air spring, a height sensor, a CPU, a cushioning bag, a first one-way valve, a first supercharger, a second one-way valve, a second supercharger, and an air storage device;

[0006] The air spring comprises an upper end cover, a bladder skin and a lower end cover.

[0007] Preferably, the height sensor is arranged inside the air spring, and the height sensor can detect the distance between the upper end cover and the lower end cover in real time, and the height sensor sends the detected data to the CPU in real time.

[0008] Preferably, the CPU can receive the altitude information sent by the altitude sensor in real time, and the CPU can control the working states of the first supercharger and the second supercharger in real time according to a preset program.

[0009] Preferably, the buffer bag is used to store gas, one end of the buffer bag is connected to the air spring, and the other end of the buffer bag is fixedly connected to the second supercharger.

[0010] Preferably, the gas storage device is provided with a gas replenishment port, and the gas storage device can replenish the internal lost gas through the gas replenishment port.

[0011] Preferably, the first one-way valve only allows gas in one direction to pass through, and the second one-way valve only allows gas in one direction to pass through.

[0012] Preferably, the first supercharger can output the input gas at a higher pressure when in operation, and the second supercharger can output the input gas at a higher pressure when in operation.

[0013] Preferably, when the distance between the upper end cover and the lower end cover of the air spring becomes smaller, the gas inside the air spring passes through the buffer bag and enters the second supercharger, and then passes through the second one-way valve and enters the gas storage device to complete exhaust;

[0014] The height sensor detects the height change inside the air spring in real time and feeds back the detected height in the form of a signal to the CPU, and the CPU compares the detected height with a preset minimum height according to a preset program:

[0015] When the detected height is lower than the preset minimum height, the CPU issues a corresponding level start instruction to the first supercharger according to a preset program based on the height difference. The first supercharger pressurizes the gas in the gas storage device to a certain intensity and delivers it to the first one-way valve. The pressurized gas then passes through the first one-way valve and enters the air spring to complete inflation.

[0016] When the detected height is greater than a preset minimum height, the CPU sends a stop operation instruction to the first supercharger.

[0017] Preferably, when the distance between the upper end cover and the lower end cover of the air spring increases, the gas in the gas storage device passes through the first supercharger and the first one-way valve and enters the air spring to complete inflation;

[0018] The height sensor detects the height change inside the air spring in real time and feeds back the detected height to the CPU in the form of a signal. The CPU compares the detected height with the preset maximum height according to a preset program:

[0019] When the detected height is greater than the preset maximum height, the CPU issues a corresponding level start instruction to the second supercharger according to the preset program based on the height difference. The second supercharger pressurizes the gas in the buffer bag to a certain intensity and transmits it to the second one-way valve. The pressurized gas then passes through the second one-way valve and enters the gas storage device to complete exhaust.

[0020] When the detected height is less than a preset maximum height, the CPU sends a stop operation instruction to the second supercharger.

[0021] According to another aspect of the present invention, there is provided an automotive seat, which includes one or more of the above-mentioned adaptive adjustment air spring systems.

[0040] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0041] Embodiment 1:

[0042] According to an implementation manner of the present invention, an adaptive air spring system 1 is designed. Figure 1 The connection diagram of the adaptive air spring system is shown. As Figure 1 shown, the adaptive air spring 1 system includes an air spring 2, a height sensor 3, a CPU 4, a buffer bladder 5, a first one-way valve 6, a first supercharger 7, a second one-way valve 8, a second supercharger 9, and a gas storage device 10.

[0043] Specifically, the air spring 2 includes an upper end cap, a bladder, and a lower end cap.

[0044] It can be seen that, compared with the traditional air spring system, this air spring system is a closed environment, which can effectively reduce the influence of the external harsh environment on it.

[0045] In some embodiments of the present invention, as Figure 1 shown, the height sensor 3 is disposed inside the air spring 2. The height sensor 3 can detect the distance between the upper end cap and the lower end cap in real time, and the height sensor 3 sends the detected data to the CPU 4 in real time.

[0046] It can be seen that this height sensor can detect the height change inside the air spring in real time and indirectly monitor the deformation amount of the air spring.

[0047] In some embodiments of the present invention, as Figure 1 shown, the CPU 4 can receive the height information sent by the height sensor 3 in real time. Subsequently, the CPU 4 compares and processes the height information according to a preset program. After that, the CPU 4 sends the processed instructions to the first supercharger 7 and the second supercharger 8 respectively for corresponding execution.

[0048] It can be seen that the realization of the adaptive adjustment function of this air spring mainly depends on the CPU's real-time collection of external information and real-time control of each internal component.

[0049] In some embodiments of the present invention, as Figure 1As shown, the buffer bag 5 is used to store gas, one end of the buffer bag 5 is connected to the air spring 2, and the other end of the buffer bag 5 is fixedly connected to the second supercharger 9.

[0050] It can be seen that the setting of the buffer bag is mainly used to assist in regulating the changes in the internal air pressure of the air spring. When the volume of the air spring changes suddenly due to some reason, the gas needs to be replenished or discharged to maintain balance. The buffer bag can serve as a temporary place to complete this task, while ensuring the normal operation of the air spring as much as possible and protecting the service life of the air spring.

[0051] In some embodiments of the present invention, Figure 1 As shown, the gas storage device 10 is provided with a gas replenishing port 11 , and the gas storage device 10 can replenish the gas lost inside through the gas replenishing port 11 .

[0052] It can be seen that the air supply port is the only channel connecting the air spring to the outside world, which minimizes the loss inside the air spring system and realizes the self-sufficiency of the internal circulation of gas; the setting of the air supply port can replenish the gas lost by the air spring in a suitable environment, so that the air pressure of the entire system always meets the predetermined air pressure.

[0053] In some embodiments of the present invention, Figure 1 As shown, the first one-way valve 6 only allows one-way passage of gas in one direction, and the second one-way valve 8 only allows one-way passage of gas in one direction.

[0054] It can be seen that the setting of the one-way valve can limit the free flow of gas, allowing gas to flow from one direction to another, and not allowing two-way flow. This restriction can ensure that the entire air spring system achieves internal circulation.

[0055] In some embodiments of the present invention, Figure 1 As shown, the first supercharger 7 can output the input gas at a higher pressure when in operation, and the second supercharger 9 can output the input gas at a higher pressure when in operation.

[0056] It can be seen that the setting of the supercharger can increase the gas pressure, converting the low-pressure gas input at one end into high-pressure gas output at the other end. This conversion breaks the originally balanced pressure state of the air spring system and achieves rapid inflation or rapid exhaust.

[0057] In some embodiments of the present invention, Figure 1 As shown, when the distance between the upper end cover and the lower end cover of the air spring 2 becomes smaller, the gas inside the air spring 2 passes through the buffer bag 5 and enters the second supercharger 9, and then passes through the second one-way valve 8 and enters the gas storage device 10 to complete exhaust;

[0058] Specifically, the height sensor 3 detects the internal height change of the air spring 2 in real time and feeds the detected height back to the CPU 4 in the form of a signal. The CPU 4 compares the detected height with the preset minimum height according to a preset program to obtain a height difference, and matches it with a preset height difference range to obtain an output instruction of the corresponding level:

[0059] Further, when the detected height is less than the preset minimum height, the CPU 4 issues a start instruction of the corresponding level to the first supercharger 7 according to the height difference according to a preset program. The first supercharger 7 pressurizes the gas in the gas storage device 10 with a certain intensity and then transports it to the first one-way valve 6. Subsequently, the pressurized gas enters the air spring 2 through the first one-way valve 6 to complete inflation;

[0060] Further, when the detected height is greater than the preset minimum height, the CPU 4 sends a stop working instruction to the first supercharger 7.

[0061] In some embodiments of the present invention, as Figure 1 shown, when the distance between the upper end cover and the lower end cover of the air spring 2 becomes larger, the gas in the gas storage device 10 enters the air spring 2 through the first supercharger 7 and the first one-way valve 6 to complete inflation;

[0062] Specifically, the height sensor 3 detects the internal height change of the air spring 2 in real time and feeds the detected height back to the CPU 4 in the form of a signal. The CPU 4 compares the detected height with the preset minimum height according to a preset program to obtain a height difference, and matches it with a preset height difference range to obtain an output instruction of the corresponding level:

[0063] Further, when the detected height is greater than the preset maximum height, the CPU 4 issues a start instruction of the corresponding level to the second supercharger 9 according to the height difference according to a preset program. The second supercharger 9 pressurizes the gas in the buffer bladder 5 with a certain intensity and then transports it to the second one-way valve 8. Subsequently, the pressurized gas enters the gas storage device 10 through the second one-way valve 8 to complete exhaust;

[0064] Further, when the detected height is less than the preset maximum height, the CPU 4 sends a stop working instruction to the second supercharger 9.

[0065] It can be seen that when the air spring is deformed under an external pressure, each system inside it will immediately operate independently and self-regulate to complete inflation and exhaust, realizing adaptive adjustment to maintain the balance and stability of the air spring system.

[0066] Embodiment Two:

[0067] According to another embodiment of the present invention, an automotive seat 12 is designed. Figure 2 The composition diagram of the automotive seat is shown, as Figure 2 shown, the automotive seat 12 includes one or more of the above-mentioned adaptive adjustment air spring systems 1.

[0068] In summary, by adopting the adaptive adjustment air spring system, the influence of the surrounding environment on it can be minimized, such as the corrosion of the inner cortex of the air spring by moisture, corrosive gases, and bacteria, the damage to it in low-temperature or high-temperature environments, and the influence of dust and fine particles on the normal operation of each component of the air spring system.

[0069] The above are only the preferred embodiments of the present invention and are 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.
