[0002] An air suspension system mainly consists of elastic elements, damping elements, guiding elements, and a height control system. The air spring is the elastic element, primarily bearing vertical loads. The shock absorber is the damping element, primarily attenuating vehicle vibrations. The thrust rod is the guiding mechanism of the air suspension, bearing and transmitting longitudinal and lateral forces and moments. The height control system includes a processor, solenoid valves, and height sensors, mainly used to adjust the air suspension's attitude.

[0003] In related technologies, for vehicles with front and rear spring brake chambers, when the vehicle is unloaded or lightly loaded, with both front and rear spring brake chambers (handbrakes) in action, the front and rear wheels of the vehicle are locked. When the vehicle is lowered, it cannot overcome the resistance connecting the suspension and the vehicle, resulting in the air springs running out of air, and the vehicle height still does not decrease. Summary of the Invention

[0004] This invention provides an electronically controlled air suspension control system, a vehicle chassis, and the vehicle itself to solve the problem in related technologies where, when the vehicle is lowered, the resistance between the suspension and the vehicle cannot be overcome, resulting in the air springs running out of air while the vehicle height has not decreased.

[0005] In a first aspect, an electronically controlled air suspension control system is provided, comprising:

[0006] A gas storage container, wherein the gas storage container is connected to two air springs;

[0007] A first solenoid valve, one end of which is connected to the gas storage container, and the other end of which is used to connect to the spring brake air chamber.

[0008] A processor, which is signal-connected to the first solenoid valve;

[0009] Before the processor controls the two air springs to release air, the processor controls the first solenoid valve to connect the air storage container and the spring brake chamber, so that the spring brake chamber is at least partially released.

[0010] In some embodiments, the electronically controlled air suspension control system further includes:

[0011] Two height sensors are connected to the processor, and each height sensor monitors the height of one of the air springs.

[0012] When the processor controls the air spring to deflate, and at least one of the height sensors detects a height drop value less than a set value, the processor controls the first solenoid valve to connect the air storage container and the spring brake chamber, so that the spring brake chamber is completely released.

[0013] In some embodiments, the electronically controlled air suspension control system further includes:

[0014] The second solenoid valve has two branch pipes that correspond one-to-one with the two air springs and are connected to the corresponding air springs. The main pipe of the second solenoid valve is connected to the gas storage container.

[0015] The processor controls the second solenoid valve to individually control the inflation or deflation of the two air springs.

[0016] In some embodiments, the second solenoid valve is integrally formed with the first solenoid valve to form a four-way pipeline solenoid valve.

[0017] In some embodiments, the gas storage container includes:

[0018] A first gas storage chamber and a second gas storage chamber are isolated from each other. The first gas storage chamber is connected to one end of the first solenoid valve, and the second gas storage chamber is connected to the main pipeline of the second solenoid valve.

[0019] In some embodiments, the electronically controlled air suspension control system further includes:

[0020] Two pressure sensors are connected to the processor, and each pressure sensor monitors the pressure of one of the air springs.

[0021] When the processor detects that the air pressure of one of the air springs is less than a set value, the processor controls the second solenoid valve to inflate the air spring until the air pressure reaches the set value.

[0022] In some embodiments, the electronically controlled air suspension control system further includes:

[0023] The remote controller is connected to the processor and sends a command signal to the processor to lower the vehicle height.

[0024] Secondly, a vehicle chassis is provided, comprising:

[0025] A gas storage container, wherein the gas storage container is connected to two air springs;

[0026] A first solenoid valve, one end of which is connected to the gas storage container;

[0027] A processor, which is signal-connected to the first solenoid valve;

[0028] Two spring brake chambers, the first of which is connected to the other end of the first solenoid valve;

[0029] Before the processor controls the two air springs to release air, the processor controls the first solenoid valve to connect the air storage container and the spring brake chamber, so that the spring brake chamber is at least partially released.

[0030] In some embodiments, the first spring brake chamber is mounted on the drive axle of the vehicle chassis.

[0031] Thirdly, a complete vehicle is provided, which includes the chassis as described above.

[0032] The beneficial effects of the technical solution provided by this invention include: before the processor controls the air spring deflation operation, the processor will control the first solenoid valve to open in advance, so that the air storage container fills the spring brake chamber with air, thereby realizing at least partial release of the spring brake chamber, reducing the resistance between the suspension and the vehicle, thus facilitating the smooth descent of the vehicle height when the air spring is deflated, and improving the problem that the height adjustment cannot be lowered when the air spring of the traditional vehicle is empty. Attached Figure Description

[0033] To more clearly illustrate the technical solutions in the embodiments of the present invention, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] This invention provides an electronically controlled air suspension control system, a vehicle chassis, and the vehicle itself to solve the problem in related technologies where, when the vehicle is lowered, the resistance between the suspension and the vehicle cannot be overcome, resulting in the air springs running out of air while the vehicle height has not decreased.

[0038] like Figure 1 As shown, this embodiment of the invention provides an electronically controlled air suspension control system, which may include: an air storage container 1, the air storage container 1 being connected to two air springs 2; a first solenoid valve 3, one end of the first solenoid valve 3 being connected to the air storage container 1, and the other end being used to connect to the spring brake chamber 4; and a processor 5, the processor 5 being signal-connected to the first solenoid valve 3; before the processor 5 controls the two air springs 2 to deflate, the processor 5 controls the first solenoid valve 3 to connect to the air storage container 1 and the spring brake chamber 4, so that the spring brake chamber 4 is at least partially released.

[0039] Before the processor 5 controls the air spring 2 to deflate, the processor 5 will control the first solenoid valve 3 to open in advance, so that the air storage container 1 fills the spring brake chamber 4 with air, thereby releasing the spring brake chamber 4 at least partially, reducing the resistance between the suspension and the vehicle, so that the height of the vehicle can be smoothly lowered when the air spring 2 deflates. This improves the problem that the height of the traditional vehicle cannot be lowered when the air spring 2 is empty.

[0040] In some embodiments, such as Figure 1 As shown, the electronically controlled air suspension control system may further include: two height sensors 6, which are signal-connected to the processor 5, and each height sensor 6 monitors the height of one of the air springs 2; when the processor 5 controls the air spring 2 to deflate, and at least one of the height sensors 6 monitors a height drop value less than a set value, the processor 5 controls the first solenoid valve 3 to connect the air storage container 1 and the spring brake chamber 4, so that the spring brake chamber 4 is completely released.

[0041] In the case where the spring brake chamber 4 is partially disengaged, and the vehicle height is lowered using the electronically controlled air suspension system, but the vehicle height does not reach the target height, the processor 5 can control the first solenoid valve 3 to open again, causing the air reservoir 1 to fill the spring brake chamber 4 with air, thus achieving complete contact between the spring brake chamber 4 and reducing the resistance between the suspension and the vehicle. This facilitates a smooth drop in vehicle height when the air spring 2 is deflated, improving the problem of minimal height adjustment in traditional vehicles when the air spring 2 is empty.

[0042] In some embodiments, such as Figure 1 As shown, the electronically controlled air suspension control system may further include: a second solenoid valve 7, the two branch pipes of the second solenoid valve 7 corresponding one-to-one with the two air springs 2 and connected to the corresponding air springs 2, the main pipe of the second solenoid valve 7 being connected to the air storage container 1; the processor 5 controls the second solenoid valve 7 to individually control the inflation or deflation of the two air springs 2.

[0043] Among them, when the second solenoid valve 7 is connected to the air storage container 1 and the two air springs 2 via the processor 5, it can inflate the air springs 2 to achieve the height increase of the whole vehicle. When the second solenoid valve 7 is connected to the outside via the processor 5, it can achieve the height decrease of the whole vehicle.

[0044] In some embodiments, the second solenoid valve 7 is integrally formed with the first solenoid valve 3 to form a four-way pipeline solenoid valve.

[0045] Among them, the second solenoid valve 7 and the first solenoid valve 3 can be replaced by a four-way pipeline solenoid valve, thereby integrating the number of components in the electronic air suspension control system, reducing the number of components, reducing production costs, and reducing the space occupancy rate of the electronic air suspension control system.

[0046] In some embodiments, the gas storage container 1 may include: a first gas storage chamber and a second gas storage chamber, wherein the first gas storage chamber and the second gas storage chamber are isolated from each other, the first gas storage chamber is connected to one end of the first solenoid valve 3, and the second gas storage chamber is connected to the main pipeline of the second solenoid valve 7.

[0047] Specifically, a partition can be used to divide the air storage container 1 into two separate, isolated air storage chambers, namely a first air storage chamber and a second air storage chamber, achieving independence between the two chambers. When the second solenoid valve 7 is damaged, the operation of the first solenoid valve 3 is not affected, thus not affecting the operation of the vehicle's spring brake air chamber 4; similarly, when the first solenoid valve 3 is damaged, the operation of the second solenoid valve 7 is not affected, thus not affecting the operation of the vehicle's air spring 2. This improves the practicality and reliability of the electronically controlled air suspension system.

[0048] In some embodiments, such as Figure 1 As shown, the electronically controlled air suspension control system may further include: two air pressure sensors 8, which are signal-connected to the processor 5, and each air pressure sensor 8 monitors the air pressure of one of the air springs 2; when the processor 5 detects that the air pressure value of one of the air springs 2 is less than a set value, the processor 5 controls the second solenoid valve 7 to inflate the air spring 2 until the air pressure value reaches the set value.

[0049] in, Figure 1 The air pressure sensor 8 at the top can be installed on the right wheel of the vehicle. Figure 1 The lower part of the air spring 2 can be installed on the left side of the vehicle. When the air pressure of the air spring 2 at the right side of the vehicle is lower than the set value, the processor 5 can control the second solenoid valve 7 to inflate the air spring 2 until the air pressure reaches the set value, thus improving the problem of uneven height between the left and right wheels when the vehicle is unloaded or lightly loaded. Similarly, when the air pressure of the air spring 2 at the left side of the vehicle is lower than the set value, the processor 5 can control the second solenoid valve 7 to inflate the air spring 2 until the air pressure reaches the set value, thus improving the problem of uneven height between the left and right wheels when the vehicle is unloaded or lightly loaded.

[0050] In some embodiments, the electronically controlled air suspension control system may further include: a remote controller 9, which is signal-connected to the processor 5, and the remote controller 9 sends a vehicle height reduction command signal to the processor 5.

[0051] The electronically controlled air suspension system can be remotely operated via remote controller 9 to achieve vehicle height adjustment.

[0052] In some embodiments, such as Figure 1 As shown, an embodiment of the present invention provides a vehicle chassis, which may include: an air storage container 1, the air storage container 1 being connected to two air springs 2; a first solenoid valve 3, one end of the first solenoid valve 3 being connected to the air storage container 1; a processor 5, the processor 5 being signal-connected to the first solenoid valve 3; two spring brake air chambers 4, the first spring brake air chamber 4 being connected to the other end of the first solenoid valve 3; before the processor 5 controls the two air springs 2 to release air, the processor 5 controls the first solenoid valve 3 to connect to the air storage container 1 and the spring brake air chamber 4, so that the spring brake air chamber 4 is at least partially released.

[0053] In some embodiments, the first spring brake chamber 4 is mounted on the drive axle of the vehicle chassis. Of course, the first spring brake chamber 4 can also be mounted on a non-drive axle of the vehicle chassis.

[0054] Before the processor 5 controls the air spring 2 to deflate, the processor 5 will control the first solenoid valve 3 to open in advance, so that the air storage container 1 fills the spring brake chamber 4 with air, thereby releasing the spring brake chamber 4 at least partially, reducing the resistance between the suspension and the vehicle, so that the height of the vehicle can be smoothly lowered when the air spring 2 deflates. This improves the problem that the height of the traditional vehicle cannot be lowered when the air spring 2 is empty.

[0055] In some embodiments, such as Figure 1 As shown, the electronically controlled air suspension control system may further include: two height sensors 6, which are signal-connected to the processor 5, and each height sensor 6 monitors the height of one of the air springs 2; when the processor 5 controls the air spring 2 to deflate, and at least one of the height sensors 6 monitors a height drop value less than a set value, the processor 5 controls the first solenoid valve 3 to connect the air storage container 1 and the spring brake chamber 4, so that the spring brake chamber 4 is completely released.

[0056] In the case where the spring brake chamber 4 is partially disengaged, and the vehicle height is lowered using the electronically controlled air suspension system, but the vehicle height does not reach the target height, the processor 5 can control the first solenoid valve 3 to open again, causing the air reservoir 1 to fill the spring brake chamber 4 with air, thus achieving complete contact between the spring brake chamber 4 and reducing the resistance between the suspension and the vehicle. This facilitates a smooth drop in vehicle height when the air spring 2 is deflated, improving the problem of minimal height adjustment in traditional vehicles when the air spring 2 is empty.

[0057] In some embodiments, such as Figure 1 As shown, the electronically controlled air suspension control system may further include: a second solenoid valve 7, the two branch pipes of the second solenoid valve 7 corresponding one-to-one with the two air springs 2 and connected to the corresponding air springs 2, the main pipe of the second solenoid valve 7 being connected to the air storage container 1; the processor 5 controls the second solenoid valve 7 to individually control the inflation or deflation of the two air springs 2.

[0058] Among them, when the second solenoid valve 7 is connected to the air storage container 1 and the two air springs 2 via the processor 5, it can inflate the air springs 2 to achieve the height increase of the whole vehicle. When the second solenoid valve 7 is connected to the outside via the processor 5, it can achieve the height decrease of the whole vehicle.

[0059] In some embodiments, the second solenoid valve 7 is integrally formed with the first solenoid valve 3 to form a four-way pipeline solenoid valve.

[0060] Among them, the second solenoid valve 7 and the first solenoid valve 3 can be replaced by a four-way pipeline solenoid valve, thereby integrating the number of components in the electronic air suspension control system, reducing the number of components, reducing production costs, and reducing the space occupancy rate of the electronic air suspension control system.

[0061] In some embodiments, the gas storage container 1 may include: a first gas storage chamber and a second gas storage chamber, wherein the first gas storage chamber and the second gas storage chamber are isolated from each other, the first gas storage chamber is connected to one end of the first solenoid valve 3, and the second gas storage chamber is connected to the main pipeline of the second solenoid valve 7.

[0062] Specifically, a partition can be used to divide the air storage container 1 into two separate, isolated air storage chambers, namely a first air storage chamber and a second air storage chamber, achieving independence between the two chambers. When the second solenoid valve 7 is damaged, the operation of the first solenoid valve 3 is not affected, thus not affecting the operation of the vehicle's spring brake air chamber 4; similarly, when the first solenoid valve 3 is damaged, the operation of the second solenoid valve 7 is not affected, thus not affecting the operation of the vehicle's air spring 2. This improves the practicality and reliability of the electronically controlled air suspension system.

[0063] In some embodiments, such as Figure 1 As shown, the electronically controlled air suspension control system may further include: two air pressure sensors 8, which are signal-connected to the processor 5, and each air pressure sensor 8 monitors the air pressure of one of the air springs 2; when the processor 5 detects that the air pressure value of one of the air springs 2 is less than a set value, the processor 5 controls the second solenoid valve 7 to inflate the air spring 2 until the air pressure value reaches the set value.

[0064] in, Figure 1 The air pressure sensor 8 at the top can be installed on the right wheel of the vehicle. Figure 1 The lower part of the air spring 2 can be installed on the left side of the vehicle. When the air pressure of the air spring 2 at the right side of the vehicle is lower than the set value, the processor 5 can control the second solenoid valve 7 to inflate the air spring 2 until the air pressure reaches the set value, thus improving the problem of uneven height between the left and right wheels when the vehicle is unloaded or lightly loaded. Similarly, when the air pressure of the air spring 2 at the left side of the vehicle is lower than the set value, the processor 5 can control the second solenoid valve 7 to inflate the air spring 2 until the air pressure reaches the set value, thus improving the problem of uneven height between the left and right wheels when the vehicle is unloaded or lightly loaded.

[0065] In some embodiments, the electronically controlled air suspension control system may further include: a remote controller 9, which is signal-connected to the processor 5, and the remote controller 9 sends a vehicle height reduction command signal to the processor 5.

[0066] The electronically controlled air suspension system can be remotely operated via remote controller 9 to achieve vehicle height adjustment.

[0067] In some embodiments, the present invention provides a complete vehicle, which may include: an air reservoir 1, the air reservoir 1 being connected to two air springs 2; a first solenoid valve 3, one end of the first solenoid valve 3 being connected to the air reservoir 1; a processor 5, the processor 5 being signal-connected to the first solenoid valve 3; two spring brake chambers 4, the first spring brake chamber 4 being connected to the other end of the first solenoid valve 3; before the processor 5 controls the two air springs 2 to release air, the processor 5 controls the first solenoid valve 3 to connect to the air reservoir 1 and the spring brake chamber 4, so that the spring brake chamber 4 is at least partially released.

[0068] In some embodiments, the first spring brake chamber 4 is mounted on the drive axle of the vehicle chassis. Of course, the first spring brake chamber 4 can also be mounted on a non-drive axle of the vehicle chassis.

[0069] Before the processor 5 controls the air spring 2 to deflate, the processor 5 will control the first solenoid valve 3 to open in advance, so that the air storage container 1 fills the spring brake chamber 4 with air, thereby releasing the spring brake chamber 4 at least partially, reducing the resistance between the suspension and the vehicle, so that the height of the vehicle can be smoothly lowered when the air spring 2 deflates. This improves the problem that the height of the traditional vehicle cannot be lowered when the air spring 2 is empty.

[0070] In some embodiments, such as Figure 1 As shown, the electronically controlled air suspension control system may further include: two height sensors 6, which are signal-connected to the processor 5, and each height sensor 6 monitors the height of one of the air springs 2; when the processor 5 controls the air spring 2 to deflate, and at least one of the height sensors 6 monitors a height drop value less than a set value, the processor 5 controls the first solenoid valve 3 to connect the air storage container 1 and the spring brake chamber 4, so that the spring brake chamber 4 is completely released.

[0071] In the case where the spring brake chamber 4 is partially disengaged, and the vehicle height is lowered using the electronically controlled air suspension system, but the vehicle height does not reach the target height, the processor 5 can control the first solenoid valve 3 to open again, causing the air reservoir 1 to fill the spring brake chamber 4 with air, thus achieving complete contact between the spring brake chamber 4 and reducing the resistance between the suspension and the vehicle. This facilitates a smooth drop in vehicle height when the air spring 2 is deflated, improving the problem of minimal height adjustment in traditional vehicles when the air spring 2 is empty.

[0073] Among them, when the second solenoid valve 7 is connected to the air storage container 1 and the two air springs 2 via the processor 5, it can inflate the air springs 2 to achieve the height increase of the whole vehicle. When the second solenoid valve 7 is connected to the outside via the processor 5, it can achieve the height decrease of the whole vehicle.

[0074] In some embodiments, the second solenoid valve 7 is integrally formed with the first solenoid valve 3 to form a four-way pipeline solenoid valve.

[0077] Specifically, a partition can be used to divide the air storage container 1 into two separate, isolated air storage chambers, namely a first air storage chamber and a second air storage chamber, achieving independence between the two chambers. When the second solenoid valve 7 is damaged, the operation of the first solenoid valve 3 is not affected, thus not affecting the operation of the vehicle's spring brake air chamber 4; similarly, when the first solenoid valve 3 is damaged, the operation of the second solenoid valve 7 is not affected, thus not affecting the operation of the vehicle's air spring 2.
