Description

[Technical Field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This disclosure claims priority to Chinese Patent Disclosure No. 202310365156.9, entitled "Integrated Adjusting System And Vehicle," filed on March 31, 2023, by BYD COMPANY LIMITED.

[0002] The present disclosure relates to the field of vehicle coordination technology, and more particularly to integrated coordination systems and vehicles. [Background technology]

[0003] In the prior art, vehicle seats can be adjusted in horizontal position and height to accommodate various occupants. The vehicle suspension system adjusts the height by setting the air suspension. However, the seat adjustment system and air suspension have complex structures, and they also occupy a large amount of interior space in the vehicle.

[0004] Furthermore, the air intakes for seat adjustment systems and air suspensions are typically located outside the passenger compartment, meaning that the air quality is significantly affected by the external environment of the passenger compartment, which can cause damage to the vehicle. Summary of the Invention

[0005] The present disclosure is intended to solve at least one of the technical problems existing in the prior art.

[0006] To this end, the present disclosure provides an integrated coordination system.

[0007] According to a first aspect of the present disclosure, an integrated adjustment system is provided for application to a vehicle, the system including: a first air intake device and a second air intake device, wherein the first air intake device is configured to perform a first function and the second air intake device is configured to perform a second function, the first function and the second function being different; and an air supply device, connected to the first air intake device to supply air to the first air intake device and connected to the second air intake device to supply air to the second air intake device, the air supply device being connected to an air inlet pipe, the air inlet pipe being suitable for drawing air from inside the vehicle cabin.

[0008] According to a second aspect of the present disclosure, there is provided a vehicle including the above-described integrated coordination system.

[0009] A technical effect of the present disclosure is that the seat adjustment device and the suspension device share one air supply device, which significantly reduces the total volume of the integrated adjustment system, saving interior space in the vehicle and reducing the cost of the vehicle.

[0010] Furthermore, the inlet pipe draws in air from inside the passenger compartment, which can ensure that the air entering the integrated conditioning system is clean, thereby avoiding the integrated conditioning system from being contaminated or damaged.

[0011] Additional aspects and advantages of the present disclosure will be set forth in part in the description that follows, and in part will be apparent from the following description, or may be learned by practice of the present disclosure. [Brief explanation of the drawings]

[Figure 2] FIG. 1 is a schematic diagram of another integrated coordination system according to an embodiment of the present disclosure. DETAILED DESCRIPTION OF THE INVENTION

[0013] The following provides a detailed description of embodiments of the present disclosure, along with examples of those embodiments shown in the accompanying drawings. In the accompanying drawings, identical or similar reference numerals refer to identical or similar components, or components having identical or similar functions. The embodiments described below with reference to the drawings are merely exemplary and are intended to illustrate the present disclosure, but may not be construed as limiting the present disclosure.

[0014] In describing the present disclosure, it should be understood that orientational or positional relationships indicated by terms such as "center," "longitudinal," "lateral," "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "peripheral," and the like are based on orientational or positional relationships shown in the accompanying drawings and are merely for the convenience of illustrating and simplifying the present disclosure. They do not indicate or imply that the referred-to devices or elements must have a particular orientation, be configured in a particular orientation, or be operated in a particular orientation, and therefore should not be construed as limiting the present disclosure.

[0015] In the description of this disclosure, unless expressly stated and defined otherwise, the terms "install," "connect," "link," and "fix" should be understood in a broad sense. For example, they can mean a fixed connection, a detachable connection, or an integral connection; they can be a mechanical connection or an electrical connection; they can be a direct connection or an indirect connection through an intermediate medium; and they can also mean an internal communication between two elements or an interactive relationship between them. Those skilled in the art can understand the specific meanings of the above terms in this disclosure according to specific circumstances.

[0016] According to one embodiment of the present disclosure, there is provided an integrated conditioning system comprising: a first air intake device and a second air intake device, the first air intake device configured to perform a first function and the second air intake device configured to perform a second function, the first function and the second function being different; and an air supply device connected to the first air intake device to supply air to the first air intake device and connected to the second air intake device to supply air to the second air intake device. The air supply device is connected to an air inlet pipe 21, the air inlet pipe 21 being suitable for drawing air from inside the vehicle cabin.

[0017] The air supply device is used to supply air at a set pressure. The air may be, for example, nitrogen, compressed air, an inert gas, etc. The first air receiving device and the second air receiving device are air receiving devices. The first air receiving device uses the air to perform a first function. The second air receiving device uses the air to perform a second function. The first function and the second function may be, for example, vehicle height adjustment, seat position adjustment, sounding a horn, controlling a valve, etc.

[0018] The passenger compartment may be, for example, a cockpit, a luggage compartment, etc. The air intake of the inlet pipe 21 is arranged inside the passenger compartment. When the integrated regulation system is operating, the air supply device draws air from inside the passenger compartment.

[0019] Generally, the external environment of a vehicle is complex. For example, the air quality in the external environment is unstable, with high dust content, high humidity, high content of toxic and harmful substances, etc. If the air intake of the inlet pipe 21 is located outside the vehicle, it may cause damage to the air compressor 4, the air spring 6, and the air bladder.

[0020] However, the air inside the vehicle cabin is usually filtered by the vehicle's air filter, so the air quality is stable and the content of harmful components is low. In this example, locating the air intake of the inlet pipe 21 inside the vehicle cabin can avoid damage caused by poor air quality to the air compressor 4, suspension device, air bladder, and first air storage unit 9.

[0021] A filter is arranged on the inlet pipe 21. The filter filters the air inside the passenger compartment, thereby ensuring good quality of the air entering the air supply device.

[0022] In this example, the first air receiving device and the second air receiving device share one air supply device, which significantly reduces the total volume of the integrated conditioning system, saving internal space in the equipment (such as a vehicle) in which the integrated conditioning system is installed, and reducing the cost of the equipment in which the integrated conditioning system is installed.

[0023] Furthermore, the inlet pipe 21 draws in air from inside the passenger compartment, which can ensure that the air entering the integrated conditioning system is clean, thereby avoiding the integrated conditioning system from being contaminated or damaged.

[0024] In one example, the first air-receiving device is one of a suspension device, a seat adjustment device, and a tire inflation device, and the second air-receiving device is one of a suspension device, a seat adjustment device, and a tire inflation device.

[0025] In this example, the air supply device may supply air to at least one of the suspension device and the seat adjustment device.

[0026] The seat adjustment device is used to adjust the side wings of the seat to adjust the passenger's posture when the vehicle is turning, reduce the passenger's tilt, and improve the driving experience. The suspension device is used to adjust the height of the vehicle body according to road conditions to ensure the vehicle's passability, reduce the vehicle's air resistance, etc.

[0027] In the present disclosure, the air supply device is used to supply high pressure air for use by the seat adjustment device and the suspension device, and the pressure of the air is set according to actual requirements.

[0028] Of course, those skilled in the art can configure the air supply device according to actual requirements, and is not limited to the above embodiments.

[0029] Both the seat adjustment device and the suspension device are supported by high pressure air to adjust the seat and vehicle body, respectively.

[0030] The seat adjustment device includes an air bladder. The air bladder abuts against the seat (such as a side wing of the seat). After the air bladder is inflated, its volume expands and compresses the seat, thereby changing the shape of the seat. After the air bladder is deflated, its volume decreases and no longer compresses the seat, causing the seat to return to its initial state.

[0031] The suspension device includes air springs 6. The air springs 6 increase in volume as air pressure increases to provide a force to lift the vehicle body and thereby increase the height of the vehicle body. As the air pressure decreases, the height of the vehicle body gradually decreases.

[0032] In the prior art, an air compressor 4 is usually installed independently to supply air to the air bladder. The air compressor 4 is connected to the air bladder. To supply air to the air spring 6, the air compressor 4 is usually installed independently, and the air compressor 4 is also connected to the air spring 6, or the air compressor 4 and the air storage tank are installed independently, and the air compressor 4 supplies air to the air storage tank, which then supplies high-pressure air to the air spring 6. The two sets of air compressor 4 and air storage tank greatly increase the volume of the two systems and occupy the interior space of the vehicle.

[0033] The tire inflation device is used to inflate a vehicle tire. For example, the tire inflation device includes an inflation line and a wheel-side valve, the inflation line is connected to the wheel-side valve, the inflation line is connected to an air supply device, and the wheel-side valve is used to control the opening and closing of an air port in the tire.

[0034] When one of the first air intake device and the second air intake device is a seat adjustment device and the other is a suspension device, the seat adjustment device and the suspension device share one air supply device, which significantly reduces the total volume of the integrated adjustment system, saves interior space of the vehicle, and reduces vehicle costs.

[0035] Furthermore, the suspension device is used much less frequently than the seat adjustment device, and the integrated adjustment system can ensure a relatively high usage frequency of the air supply device, thereby avoiding idle loss of the air supply device caused by long-term non-use.

[0036] Furthermore, the suspension device typically adjusts the vehicle height when the vehicle is stationary or in response to changes in vehicle speed while driving straight ahead. The seat adjustment device typically is used when the vehicle is turning. Therefore, the functions of the suspension device and the seat adjustment device do not overlap in terms of usage time, allowing the air supply device to be used to its full extent.

[0037] Furthermore, since the operation of both the suspension device and the seat adjustment device is related to the vehicle's motion state, control of the suspension device and the seat adjustment device may be achieved through a single control device to enable better scheduling of the control device's resources and coordination of control strategies by coordinating the control of multiple functional modules (such as multiple solenoid valves and pressure sensors).

[0038] Furthermore, for the suspension device and the seat adjustment device, both are triggered and controlled based on the vehicle's position and acceleration states, so the vehicle-wide signal only needs to be sent once instead of multiple times, saving the computing resources of the vehicle control device and improving the operating efficiency of the vehicle-wide system.

[0039] Furthermore, since the control of the two systems can be achieved through one control device, for example, the function of the seat adjustment device can be integrated into the control device of the suspension device, so there is no need to install two independent control devices, which can save costs for the vehicle.

[0040] In one example, the air supply device is configured in a first state to supply air to a first air receiving device, in a second state to supply air to a second air receiving device, and in a third state to supply air to both the first air receiving device and the second air receiving device.

[0041] In this example, multiple air supply modes of the air supply device can be realized by controlling various operating states.

[0042] In one example, the air supply device includes an air generating unit and a first air storage unit, and the air generating unit is configured to supply air to the first air storage unit to ensure that the first air storage unit supplies air to the first air receiving device and / or the second air receiving device.

[0043] For example, the air generating unit is an air compressor 4. Of course, the air generating unit may also be a nitrogen compressor, an inert gas compressor, etc. The first air storage unit is used to store air. For example, the first air storage unit is an air storage tank. In this example, the first air storage unit can store air to supply air to the first air receiving device and / or the second air receiving device. In this way, the first air storage unit can store air at a set pressure. Compared to the air generating unit, the first air storage unit can continuously supply a large amount of air. When the air supply is intermittent, this avoids frequent opening and closing of the air generating unit.

[0044] In one example, the air supply device includes an air generating unit, a first air storage unit, and a second air storage unit, wherein the air generating unit is configured to supply air to the first air storage unit, and the air generating unit or the first air storage unit is configured to supply air to the second air storage unit.

[0045] As shown in FIGS. 1 and 2, the air generating unit is an air compressor 4. Both the first air storage unit 9 and the second air storage unit 20 are air storage tanks. Under normal circumstances, the volume of the first air storage unit 9 is larger than the volume of the second air storage unit 20, and the air pressure in the first air storage unit 9 is higher than the air pressure in the second air storage unit 20. When the air pressure in the first air storage unit 9 is lower than a set value, the air generating device is activated to supply air to the first air storage unit.

[0046] If the air pressure in the second air storage unit 20 is lower than the set value, there are two options: one is to activate the air generating device to supply air to the second air storage unit 20, as shown in Figure 1; the other is to open the first air storage unit 9 to supply air to the second air storage unit 20, as shown in Figure 2.

[0047] In this example, since the air pressure in the second air storage unit 20 is lower than the air pressure in the first air storage unit 9, the first air storage unit 9 can also supply air to the second air storage unit 20. Compared with the method in which the air compressor 4 supplies air to the second air storage unit 20, the first air storage unit 9 has a larger volume, so that the first air storage unit 9 can supply air to the second air storage unit 20 in a timely manner, avoiding the problem of frequent opening and closing of the air generating unit and the inability to provide a sufficient amount of air in a short period of time. It should be noted that in the example shown in FIGS. 1 and 2 , the first conduit 100 includes a conduit connecting the air compressor 4 to the suspension device and a conduit connecting the first air storage unit 9 to the suspension device.

[0048] In other examples, the air generating unit may be, but is not limited to, an air compressor 4, a nitrogen compressor, an inert gas compressor, an air storage unit, etc. The air generating unit may also be a nitrogen generator used to prepare nitrogen. The air generating unit may also include a nitrogen generator and a nitrogen compressor. The nitrogen compressor is used to pressurize the nitrogen prepared by the nitrogen generator and supply it to the seat adjustment device or suspension device.

[0049] In one embodiment, the first air receiving device is a suspension device and the second air receiving device is a seat adjustment device, as shown in Figure 1. The air supply device supplies air to the first air receiving device through a first conduit 100 and to the second air receiving device through a second conduit 200. A distribution valve is disposed between the first air storage unit and the suspension device.

[0050] The distribution valve 7 is used to control the opening and closing of the suspension device and the first air storage unit 9. For example, the suspension device includes a plurality of air springs 6, such as four. The distribution valve 7 includes four air spring solenoid valves 5 corresponding to the air springs 6 and a storage unit solenoid valve 8 corresponding to the first air storage unit 9. When the vehicle body is raised, the air spring solenoid valves 5 and the storage unit solenoid valves 8 are opened, and the high-pressure air in the first air storage unit 9 enters the four air springs 6, thereby increasing the height of the vehicle body. When it is necessary to lower the vehicle body, the storage unit solenoid valve 8 is closed to facilitate the air in the air springs 6 being released outside the vehicle compartment. The vehicle compartment may be, for example, a cockpit or a luggage compartment.

[0051] In one example, a group of pressure limiting valves is disposed between the second air storage unit 20 and the seat adjustment device. The group of pressure limiting valves is mounted on the second conduit 200. The group of pressure limiting valves can control the air pressure downstream of the group of pressure limiting valves on the second conduit 200 to meet the operating requirements of the seat adjustment device.

[0052] 1, the pressure limiting valve group includes a first pressure limiting valve 19 and a second pressure limiting valve 18. The first pressure limiting valve 19 is disposed on a second conduit 200. The second conduit 200 includes an exhaust branch pipe, and the second pressure limiting valve 18 is disposed on the exhaust branch pipe.

[0053] In this example, the air pressure in the second air storage unit 20 is higher than the operating pressure of the seat adjustment device. To accommodate the operating pressure of the seat adjustment device, a first pressure limiting valve 19 is installed on the second pipeline 200. Those skilled in the art can select the specifications of the first pressure limiting valve 19 according to the air pressure in the second air storage unit 20 and the operating pressure of the seat adjustment device. The exhaust branch pipe is used to exhaust the air in the second pipeline 200. For example, the second pressure limiting valve 18 is an electromagnetic valve or a pneumatic valve. When the second pipeline 200 is exhausting air, the second pressure limiting valve 18 is opened so that the air in the air bladder can be quickly vented. Installing the second pressure limiting valve 18 on the second pipeline 200 to exhaust air can achieve faster exhaust.

[0054] Furthermore, by installing the exhaust branch pipe and the second pressure limiting valve 18, the high pressure air can also be relieved through the second pressure limiting valve 18 in case the first pressure limiting valve 19 fails, to avoid damage to the seat adjustment device caused by excessive air pressure.

[0055] In one example, pressure regulation valves are disposed on the second conduit 200 and are used to regulate the air pressure of the seat adjustment device, which includes an air bladder, whose inflation, deflation, and pressure maintenance are controlled by the pressure regulation valves.

[0056] In one example, the pressure regulating valve group includes a first valve and a second valve. The first valve has a first end, a second end, and a third end. The first end is connected to an air supply device, the second end is connected to a seat adjustment device, and the third end is connected to a first exhaust pipe line. The second valve is disposed on the first exhaust pipe line to control opening and closing of the first exhaust pipe line. Any two of the first end, the second end, and the third end are selectively connected.

[0057] The first valve and the second valve may be solenoid valves, pneumatic valves, etc. As shown in FIG. 1 , the first valve is an intake solenoid valve 10, and the second valve is an exhaust solenoid valve 13. The seat adjustment device includes a driver seat adjustment mechanism and a passenger seat adjustment mechanism. A driver control valve 15 and a passenger control valve 16 are mounted on the second conduit 200 to control the air circuits of the driver seat adjustment mechanism and the passenger seat adjustment mechanism, respectively. Of course, the driver control valve 15 and the passenger control valve 16 do not have to be mounted in order to simplify the seat adjustment device.

[0058] Both the driver's seat adjustment mechanism and the passenger seat adjustment mechanism include air bags. For example, the air bags include a left side wing air bag 12 that faces the position of the left side wing of the seat and a right side wing air bag that faces the position of the right side wing of the seat. The left side wing air bag 12 and the right side wing air bag adjust the angle, height, etc. of the left and right side wings of the seat, respectively, thereby reducing the leaning of the occupant's body.

[0059] Take the left side wing air bladder 12 of the driver's seat adjustment mechanism as an example for illustration. When the vehicle turns right, the occupant leans to the left. At this time, the driver control valve 15 and the intake solenoid valve 10 are open, and the exhaust solenoid valve 13 is closed. The high-pressure air in the second air storage unit 20 passes through the first pressure limiting valve 19, the driver control valve 15, and the intake solenoid valve 10 and reaches the left side wing air bladder 12. After the left side wing air bladder 12 is inflated, it expands, thus changing the angle of the left side wing to support the occupant and reduce the occupant's leaning to the left. When the air pressure in the left side wing air bladder 12 reaches a set value, the intake solenoid valve 10 is closed, and the left side wing air bladder 12 maintains the pressure. When the vehicle turns to travel straight, the driver resumes sitting upright. At this time, the exhaust solenoid valve 13 is opened to deflate the left side wing air bladder 12. The volume of the left side wing air bladder 12 decreases, and the left side wing returns to its initial state.

[0060] In this example, the structure of the first valve can simplify the connection mode of the second valve, making it convenient for assembling and disassembling the seat adjusting device.

[0061] 1 , the air generating unit is connected to a first pipeline 100, and is also connected to a second air storage unit 20 through a third pipeline 300, and the air generating unit further includes a communication pipeline 41 connecting the first pipeline 100 and the third pipeline 300. A communication valve 42 is disposed on the communication pipeline 41, and the first air storage unit 9 supplies air to the second air storage unit 20 through the first pipeline 100, the communication pipeline 41, and the third pipeline 300.

[0062] In this example, the first conduit 100 and the third conduit 300 are separated by an air generating unit such as an air compressor 4. The second conduit 200 and the third conduit 300 are separated by a second air storage unit 20. As shown in FIG. 1 , the air outlet of the air generating unit is connected to the first conduit 100. The air generating unit can supply air to the suspension device and the first air storage unit 9 through the first conduit 100. The third conduit 300 is used to supply air to the second air storage unit 20, exhaust air from the suspension device, etc.

[0063] The communicating pipe 41 connects the first pipe 100 and the third pipe 300. This allows the suspension device to discharge air without passing through the air compressor 4, and also allows the first air storage unit 9 to supply air to the second air storage unit 20. A communicating valve 42 is installed on the communicating pipe 41, and the communicating valve 42 is an electric valve or a pneumatic valve. The on / off of the communicating pipe 41 is controlled by the communicating valve 42. When the first air storage unit 9 supplies air to the second air storage unit 20, the first air storage unit 9 supplies air to the second air storage unit 20 through the first pipe 100, the communicating pipe 41, and the third pipe 300.

[0064] In one example, the third conduit 300 is connected to the second exhaust conduit, and the suspension device exhausts air through the first conduit 100, the communication conduit 41, the third conduit 300, and the second exhaust conduit.

[0065] For example, the second exhaust line is a branch line connected to the third line 300, and a safety valve 3 is installed on the second exhaust line. The safety valve 3 is an electric valve or a pneumatic valve. Exhaust is performed by controlling the opening of the safety valve 3.

[0066] In one example, the second exhaust line is connected to the suspension device, and the exhaust port of the second exhaust line is adapted to vent air outside the vehicle cabin.

[0067] The second exhaust line can be directly connected to the suspension device, or the second exhaust line can be indirectly connected to the suspension device. For example, the suspension device is connected through the first line 100, the communication line 41, the third line 300, and the second exhaust line.

[0068] For example, as shown in FIG. 1 , the second exhaust pipe is connected to the third pipe 300, and the safety valve 3 is installed on the second exhaust pipe, and the safety valve 3 is arranged outside the cockpit. The safety valve 3 is an electromagnetic valve, a pneumatic valve, etc. The safety valve 3 can release air discharged from the suspension device. The air discharged from the suspension device reaches the second exhaust pipe through the first pipe 100, the connecting pipe 41, and the third pipe 300, and is then released outside the cockpit, thereby avoiding the above-mentioned adverse effects of the air on the air environment in the cockpit.

[0069] In one example, as shown in Figure 1, a first check valve 2 is mounted on the inlet pipe 21. The first check valve 2 is configured to allow air to flow towards the air supply device.

[0070] For example, one end of the third conduit 300 is connected to the inlet pipe 21, and the other end of the third conduit 300 is connected to the air intake of the air compressor 4. The first check valve 2 does not allow air to flow in the reverse direction. In this way, air on the side of the first check valve 2 that is closer to the air compressor is not bled through the inlet pipe 21.

[0071] In one example, as shown in FIG. 1 , a second check valve 1 is mounted on the third conduit 300, and the second check valve 1 is configured to allow air to flow toward the second air storage unit 20.

[0072] In this example, the second check valve 1 allows air to enter the second air storage unit 20, but does not allow the air in the second air storage unit 20 to enter the air compressor 4, the suspension device, or the first air storage unit 9. In this way, the second check valve 1 can effectively prevent the air in the second air storage unit 20 from being vented when the safety valve 3 is opened.

[0073] The installation of the first check valve 2 and the second check valve 1 allows the integrated regulating system to automatically regulate the intake and exhaust of air. When air is being taken in, the external atmospheric pressure is greater than the air pressure in the third pipeline 300. Under the pressure differential, the first check valve 2 automatically opens, and the second check valve 1 automatically closes because its directional and pressure differential conditions do not meet the opening conditions. Air enters the air compressor 4 through the inlet pipe 21 and the third pipeline 300. When air is being supplied to the second air storage unit 20, the air pressure upstream of the second check valve 1 is greater than the air pressure downstream of the second check valve 1. Under the pressure differential, the second check valve 1 automatically opens, and the first check valve 2 automatically closes because its directional and pressure differential conditions do not meet the opening conditions. Air reaches the second air storage unit 20 through the third pipeline 300. This mounting method can simplify the pipeline design of the air compressor 4.

[0074] In one example, as shown in FIG. 1, the suspension device includes a plurality of air springs 6, each of which is connected to an air supply device.

[0075] The multiple air springs 6 are distributed at various positions on the vehicle body. For example, the air springs 6 correspond to the positions of the wheels. This allows for smoother and more uniform adjustment of the vehicle body height. Each air spring 6 is controlled by an air spring solenoid valve 5 for air intake, exhaust, and pressure maintenance. A storage unit solenoid valve 8 is used to control the air supply, exhaust, and pressure maintenance of the first air storage unit 9.

[0076] When the first air storage unit 9 is inflated, the air compressor 4 is turned on, the communication valve 42 and the plurality of air spring solenoid valves 5 are closed, and the storage unit solenoid valve 8 is open. Air enters the air compressor 4 through the inlet pipe 21 and a portion of the third pipe 300. The air compressed by the air compressor 4 inflates the first air storage unit 9 through the first pipe 100.

[0077] When the air pressure in the first air storage unit 9 reaches the first set air pressure, the storage unit solenoid valve 8 is closed and the air compressor 4 is turned off, so that the first air storage unit 9 maintains pressure.

[0078] When it is necessary to raise the height of the vehicle body, the communication valve 42 is closed, the air spring solenoid valve 5 and the storage unit solenoid valve 8 are opened, and the high-pressure air in the first air storage unit 9 enters the air spring 6 through the first pipe 100, thus raising the height of the vehicle body.

[0079] When it is necessary to lower the vehicle body height, the storage unit solenoid valve 8 is closed, the air spring solenoid valve 5 and the communication valve 42 are opened, and the air in the air spring 6 is released through the first pipe 100, the communication pipe 41, a portion of the third pipe 300, and the second exhaust pipe.

[0080] The plurality of air spring solenoid valves 5 and the storage unit solenoid valve 8 form an assembly, which makes the suspension device more integrated and easier to install and disassemble.

[0081] In one example, as shown in FIG. 1, a second air storage unit 20 is connected to a first air storage unit 9, and the air pressure in the second air storage unit 20 is lower than the air pressure in the first air storage unit 9.

[0082] In this example, the air pressure in the second air storage unit 20 is lower than the air pressure in the first air storage unit 9, so the first air storage unit 9 can supply air to the second air storage unit 20. Compared with the method in which the air compressor 4 supplies air to the second air storage unit 20, the first air storage unit 9 has a larger volume, so the first air storage unit 9 can supply air to the second air storage unit 20 in a timely manner, avoiding the problem of the air compressor 4 frequently opening and closing and being unable to provide a sufficient amount of air in a short period of time.

[0083] 1, the second air storage unit 20 is connected to the first air storage unit 9 through the third pipeline 300, the connecting pipeline 41, and the first pipeline 100. According to this connection method, by using the original pipeline, the first air storage unit 9 can supply air to the second air storage unit 20 simply by controlling the opening and closing of the valve.

[0084] In one example, as shown in FIG. 1, the first air storage unit 9 supplies air to the second air storage unit 20 through the first pipe 100, the connecting pipe 41, and the third pipe 300.

[0085] In this example, the communication line traverses the air compressor 4 to connect the first line 100 and the third line 300. This can prevent air from entering the air compressor 4. It should be noted that when the first air storage unit 9 supplies air to the second air storage unit 20, the air compressor stops supplying air to the first line 100.

[0086] In one example, as shown in FIG. 1, when the air pressure in the second air storage unit 20 is lower than a set value, the storage unit solenoid valve 8 and the communication valve 42 are opened.

[0087] In this way, the storage unit solenoid valve 8 and the communication valve 42 can efficiently control the air supply from the first air storage unit 9 to the second air storage unit 20.

[0088] In one example, as shown in FIG. 1, a first pressure sensor 14 is mounted on the second conduit 200, and the first pressure sensor 14 is used to detect the air pressure in the second air storage unit 20.

[0089] When the air pressure in the second air storage unit 20 is lower than the second set air pressure, the air compressor 4 or the first air storage unit 9 supplies air to the second air storage unit 20 .

[0090] In one example, the integrated control system further includes a control device used to control inflation, venting, and pressure retention of the suspension device, the first air storage unit 9, and the seat adjustment device.

[0091] For example, the control device may be a control device such as a vehicle control device or a dedicated control device for the integrated adjustment device, which may control the opening and closing of the air spring solenoid valve 5, the storage unit solenoid valve 8, the intake solenoid valve 10, the exhaust solenoid valve 13, the communication valve 42, the safety valve 3, the second pressure limiting valve 18, etc.

[0092] In one example, the air supply device is arranged with an auxiliary interface. The auxiliary interface is used for connection with other devices other than the first air receiving device and the second air receiving device. For example, the other devices may be, but are not limited to, an air dust removal device and an air pump outside the vehicle. In this example, the auxiliary interface can supply air to the other devices, thus meeting various air usage requirements.

[0093] According to another embodiment of the present disclosure, there is provided a vehicle, the vehicle including the integrated coordination system described above.

[0094] The vehicle has high integration characteristics and can realize seat and body height adjustment.

[0095] (1) Adjusting the height of the vehicle body in a stationary state. This is used to automatically adjust the height of the vehicle body according to the number of occupants in the vehicle or the mass of the vehicle in order to maintain the height required for driving the vehicle and the stability of the driving state of the vehicle. The height adjustment of the vehicle body may be the height adjustment of the air springs 6 corresponding to all wheels of the vehicle, or it may be the height adjustment of only the air spring 6 corresponding to one wheel.

[0096] Operating conditions for adjusting the height of the air springs 6 corresponding to all wheels of the vehicle. When it is necessary to raise the vehicle body, the communication valve 42 is closed, and the four air spring solenoid valves 5 corresponding to the air springs 6 and the storage unit solenoid valve 8 corresponding to the first air storage unit 9 in the distribution valve 7 are opened, so that the high-pressure air in the first air storage unit 9 enters the four air springs 6, thereby increasing the height of the vehicle body. When it is necessary to lower the vehicle body, the storage unit solenoid valve 8 is closed, the communication valve 42 is opened, and the air in the air springs 6 is vented outside the cockpit through the safety valve 3.

[0097] The operating conditions for adjusting the height of the air spring 6 corresponding to one wheel are as follows: the air spring solenoid valve 5 and storage unit solenoid valve 8 corresponding to the wheel that needs to be raised are opened. At this time, the high-pressure air in the first air storage unit 9 enters the air spring 6 corresponding to this air spring solenoid valve 5, which expands, thus raising the part of the vehicle body corresponding to that wheel. When it is necessary to lower the vehicle body, the storage unit solenoid valve 8 is closed and the communication valve 42 is opened, and the air in the air spring 6 is released to the outside of the cockpit through this air spring solenoid valve 5, the communication valve 42, and the safety valve 3.

[0098] (2) Controlling vehicle height during vehicle operation. This is used to improve the vehicle's directional stability when driving at high speeds. When the control device determines that the vehicle speed of a vehicle traveling straight reaches or exceeds a set speed, it sends a control signal to increase the damping force of the electronically controlled shock absorber. At the same time, the control device controls the distribution valve 7 to exhaust air from the air springs 6 and lower the vehicle height, thereby reducing air resistance, lowering the center of gravity of the vehicle, and improving handling stability during high-speed driving. At this time, the connecting valve 42 and all air spring solenoid valves 5 are opened, and the air in the air springs 6 is released outside the cockpit through the air spring solenoid valves 5, connecting valves 42, and safety valves 3 to lower the vehicle height.

[0099] When the vehicle speed while traveling straight drops below the set speed, the communication valve 42 is closed and the storage unit solenoid valve 8 and all the air spring solenoid valves 5 are opened to inflate the four air springs 6 and raise the height of the vehicle body.

[0100] (3) Suspension device overload protection. The ECU sets the maximum allowable air pressure for the suspension device. If the air pressure in the air spring 6 is equal to or greater than the maximum allowable air pressure, the air spring 6 is deflated and the vehicle height is lowered. At this time, the communication valve 42 and all air spring solenoid valves 5 are opened, and the air in the air spring 6 is released to the outside of the cockpit through the air spring solenoid valves 5, the communication valve 42, and the safety valve 3 to lower the vehicle height.

[0101] When the vehicle needs to return to normal, for example, when the air pressure of the air spring 6 is below the minimum allowable air pressure, the load on the vehicle needs to be reduced, such as by unloading an overweight item. When the air pressure of the air spring 6 is lower than the maximum allowable air pressure and the vehicle is restarted, the vehicle will return to normal.

[0102] (4) Seat side wing support during steering. This is used to improve the lateral stability of the vehicle occupant relative to the seat when the vehicle body is subjected to lateral forces. When the vehicle is turning, for example, when at least one of the lateral acceleration, roll angle, and roll angular velocity is equal to or greater than a set value, the driver control valve 15 and the corresponding intake solenoid valve 10 are opened and the exhaust solenoid valve 13 is closed. The high-pressure air in the second air storage unit 20 enters the air bladders, such as the left side wing bladder 12, through the first pressure limiting valve 19, the driver control valve 15, and the corresponding intake solenoid valve 10 to support the occupant's lower back and prevent the occupant from leaning over; when at least one of the vehicle's lateral acceleration, roll angle, or roll angular velocity is less than a set value, the intake solenoid valve 10 closes and the exhaust solenoid valve 13 opens, the air in the air bladders (such as the left side wing bladder 12) is vented outside the cockpit, and the left side wing of the seat no longer provides support.

[0103] It should be noted that in the above various use modes, the opening and closing of various valves is controlled and completed by the control device. When the suspension device is operating, the first air storage unit 9 supplies air only to the suspension device and stops supplying air to the seat adjustment device; when the seat adjustment device is operating, the second air storage unit 20 supplies air only to the seat adjustment device, and the first air storage unit 9 or the air compressor 4 stops supplying air to the second air storage unit 20.

[0104] According to another embodiment of the present disclosure, a vehicle is provided. The vehicle includes the above-described integrated adjustment system. A first pressure limiting valve 19 is mounted on the second duct 200, the seat adjustment device includes an air bladder, the air bladder is disposed behind the left wing of the seat, and the air bladder is connected to the second duct 200, and a first valve and a second valve are mounted on the second duct 200. The first valve can control air intake of the air bladder, and the second valve is used to control air discharge of the air bladder.

[0105] When a signal is received indicating that the vehicle is turning, the first pressure limiting valve and the intake valve are opened to inflate an air bladder behind the side wing on the leaned side.

[0106] In this example, the intake valve is intake solenoid valve 10, and the exhaust valve is exhaust solenoid valve 13. When the vehicle turns right, the occupant's body leans to the left. After receiving a right turn signal, the control device sends a control signal to open driver control valve 15 and the corresponding intake solenoid valve 10 and close exhaust solenoid valve 13. The high-pressure air in second air storage unit 20 enters an air bladder, such as left side wing air bladder 12, through first pressure limiting valve 19, driver control valve 15, and the corresponding intake solenoid valve 10 to support the occupant's waist and prevent the occupant from leaning. In one example, the second valve is opened when a signal is obtained indicating that the vehicle is no longer turning.

[0107] For example, when the control device gets a signal that the vehicle is driving straight or the vehicle has stopped, the control device sends a control signal to open the exhaust solenoid valve 13, the left side wing air bladder 12 expels air, and the left side wing returns to its initial state.

[0108] The signal comprises at least one of lateral acceleration, roll angle, or roll angular rate, which allows the controller to accurately determine the state of the vehicle and precisely control the operation of the integrated coordination system.
