[0011] Further aspects and advantages of this application are partially described in the following description, partially apparent from the following description, or can be acquired through the practice of this application. [Brief explanation of the drawing]
[0012] [Figure 1] This is a diagram of an integrated adjustment system according to one embodiment of the present application. [Figure 2] This is a diagram of another integrated adjustment system according to one embodiment of the present application. [Modes for carrying out the invention]
[0013] Embodiments of this application are described in detail below, examples of which are shown in the accompanying drawings, and throughout, the same or similar reference numerals represent the same or similar elements or elements having the same or similar function. The embodiments described below with reference to the accompanying drawings are illustrative and are intended to illustrate this application and should not be construed as limitations thereon.

Therefore, it should be understood that these terms should not be construed as limiting this application.
[0015] In this application, unless otherwise expressly specified and limited, terms such as βattach,β βjoin,β βconnect,β and βfastenβ should be understood in a broad sense, including fastening connections, removable connections, or integral connections, mechanical or electrical connections, direct connections, indirect connections via an intermediate medium, internal connections between two elements, or interactions between two elements. Those skilled in the art will understand the specific meanings of the aforementioned terms in this application according to the specific context.
[0016] According to one embodiment of the present application, an integrated adjustment system for application to a vehicle is provided. The system includes first and second gas containment devices, the first gas containment device being configured to perform a first function and the second gas containment device being configured to perform a second function, wherein the first function is distinct from the second function; and a gas supply device being connected to the first gas containment device and supplying gas to the first gas containment device, and connected to the second gas containment device and supplying gas to the second gas containment device.
[0017] The gas supply device is configured to supply gas. The gas may be, for example, nitrogen, compressed air, or an inert gas. The first and second gas containment devices are devices for containing gas. The first gas containment device utilizes gas to perform a first function. The second gas containment device utilizes gas to perform a second function. The first and second functions are, for example, vehicle height adjustment, seat position adjustment, horn, and valve control.
[0018] In this example, the first and second gas containment units share a single gas supply unit, which significantly reduces the overall size of the integrated control system, saves internal vehicle space, and lowers vehicle costs.
[0019] In one example, a third gas storage device is further included, and the gas supply device is connected to the third gas storage device to supply gas to the third gas storage device. The third gas storage device is configured to realize a third function. The third function is different from the first function and the second function.
[0020] In this example, the gas supply device supplies gas to the first gas storage device, the second gas storage device, and the third gas storage device, thereby reducing the size of the integrated adjustment system.
[0021] In one example, the first gas storage device, the second gas storage device, and / or the third gas storage device are components of a vehicle. For example, the aforementioned gas storage device is a component for realizing the lifting of the vehicle body, a component for realizing the inflation of the tire, a component for realizing the horn, a component for realizing the adjustment of the seat, a component for realizing the steering, etc.
[0022] In one example, the first gas storage device is one or more of a suspension device, a seat adjustment device, and a tire inflation device. The second gas storage device is one or more of a suspension device, a seat adjustment device, and a tire inflation device. The third gas storage device is one or more of a suspension device, a seat adjustment device, and a tire inflation device.
[0023] In this example, the gas supply device can supply gas to at least one of a suspension device, a seat adjustment device, and a tire inflation device. Of course, the first gas storage device, the second gas storage device, and the third gas storage device are not limited to the foregoing embodiments. Alternatively, they may be other devices of the vehicle that require gas, and those skilled in the art can configure them according to actual needs.
[0024] The seat adjustment device is configured to adjust the side portion of the seat in order to adjust the posture of the passenger when the vehicle turns, reduce the inclination of the passenger, and improve the driving experience. The suspension device is configured to adjust the height of the vehicle body according to the road conditions, ensure the passability of the vehicle, reduce the air resistance of the vehicle, and the like.
[0025] In the present application, the gas supply device is configured to supply high-pressure gas to the seat adjustment device and the suspension device for use. The gas pressure is set according to the actual needs.
[0026] Of course, those skilled in the art can configure the gas supply device according to the actual needs, but this is not limited to the foregoing embodiments.
[0027] Both the seat adjustment device and the suspension device provide a supporting force via high-pressure gas and adjust the seat and the vehicle body individually.
[0028] The seat adjustment device includes an airbag. The airbag abuts against the seat (for example, the side surface of the seat). After inflation, the size of the airbag expands and presses the seat, thereby changing the shape of the seat. After contraction, the size of the airbag contracts and no longer presses the seat. As a result, the seat returns to its initial state.
[0029] The suspension device includes an air spring 6. As the air pressure increases, the air spring 6 expands in size and provides a force to lift the vehicle body, and the height of the vehicle body increases. As the air pressure decreases, the height of the vehicle body gradually decreases.
[0030] Conventional technology typically requires a separate air compressor 4 to supply air to the airbag. The air compressor 4 is connected to the airbag. Similarly, a separate air compressor 4 is typically required to supply air to the air spring 6, and the air compressor 4 is connected to the air spring 6. Alternatively, the air compressor 4 and the gas storage tank can be placed separately, with the air compressor 4 supplying air to the gas storage tank, and the gas storage tank supplying high-pressure air to the air spring 6. The arrangement of two air compressors 4 and two gas storage tanks significantly increases the size of the two systems and occupies a considerable amount of interior space in the vehicle.
[0031] A tire inflator is configured to inflate the tires of a vehicle. For example, a tire inflator includes an expansion line and a wheel-side valve, the expansion line being connected to the wheel-side valve, and the expansion line being connected to a gas supply device. The wheel-side valve is configured to control the opening and closing of the tire's air vent.
[0032] Under the condition that one of the first and second gas containment devices is a seat adjustment device and the other is a suspension device, the seat adjustment device and the suspension device share a single gas supply device, thereby significantly reducing the overall size of the integrated adjustment system, saving interior space in the vehicle, and lowering the cost of the vehicle.
[0033] In addition, the suspension system is used far less frequently than the seat adjustment system. The integrated adjustment system can ensure a high frequency of use of the gas supply system, thereby avoiding unnecessary losses of the gas supply system due to prolonged downtime.
[0034] In addition, the suspension system typically adjusts the vehicle's height when the vehicle is stationary and adjusts the vehicle's height in accordance with changes in vehicle speed when the vehicle is moving straight. The seat adjustment system is typically used when the vehicle is turning. Therefore, the functions of the suspension system and the seat adjustment system do not overlap in terms of usage time, and as a result, the gas supply system can be utilized to its fullest potential.
[0035] In addition, since the operation of both the suspension system and the seat adjustment system is related to the vehicle's motion state, in the case of the suspension system and the seat adjustment system, coordinated control of multiple functional modules (e.g., multiple solenoid valves or pressure sensors) can be achieved through a single control unit. As a result, the resources of the control unit can be more appropriately scheduled, and the control strategy can be more appropriately adjusted.
[0036] In addition, in the case of suspension and seat adjustment devices, both devices are triggered and controlled based on the vehicle's position and acceleration state, so the vehicle signal needs to be sent only once rather than multiple times. This saves computational resources for the overall vehicle control system and improves the overall system's operational efficiency.
[0037] In addition, because the two systems can be controlled by a single control unit, for example, the functions of the seat adjustment device can be integrated into the control unit of the suspension system, eliminating the need for two separate control units and thus reducing vehicle costs.
[0038] In one example, In the first state, the gas supply device is configured to supply gas to the first gas containment device. In the second state, the gas supply device is configured to supply gas to the second gas containment device. In the third state, the gas supply device is configured to supply gas to the third gas containment device. In the fourth state, the gas supply device is configured to supply gas to the first and second gas containment devices. In the fifth state, the gas supply device is configured to supply gas to the third gas containment device and the second gas containment device. In the sixth state, the gas supply device is configured to supply gas to the third gas containment device and the first gas containment device. In the seventh state, the gas supply device is configured to supply gas to the first gas containment device, the second gas containment device, and the third gas containment device. In this example, multiple gas supply modes for a gas supply device can be realized by controlling different operating states, for example, by controlling the operating state via a control device.
[0039] In one example, the gas supply device includes a gas generation unit and a first gas storage unit. The gas generation unit is configured to supply gas to the first gas storage unit, and as a result, the first gas storage unit supplies gas to a first gas containment device and / or a second gas containment device.
[0040] For example, the gas generation unit is an air compressor 4. Of course, the gas generation unit may alternatively be a nitrogen compressor, an inert gas compressor, etc. The first gas storage unit is configured to store gas. For example, the first gas storage unit is a gas storage tank. In this example, the first gas storage unit can store gas to supply gas to the first gas containment device and / or the second gas containment device. In this way, the first gas storage unit can store gas at a specified pressure. Compared to the gas generation unit, the first gas storage unit can supply a large amount of gas continuously. If the gas supply is intermittent, it prevents the gas generation unit from being frequently turned on and off.
[0041] In one example, the integrated control system includes a gas generation unit, a first gas storage unit, and a second gas storage unit. The gas generation unit is configured to supply gas to the first gas storage unit. Either the gas generation unit or the first gas storage unit is configured to supply gas to the second gas storage unit.
[0042] As shown in Figures 1 and 2, the gas generation unit is the air compressor 4. The first gas storage unit 9 and the second gas storage unit 20 are both gas storage tanks. Normally, the volume of the first gas storage unit 9 is larger than the volume of the second gas storage unit 20. The gas pressure in the first gas storage unit 9 is higher than the gas pressure in the second gas storage unit 20. If the gas pressure in the first gas storage unit 9 is below a specified value, the gas generation device is activated to supply gas to the first gas storage unit.
[0043] If the gas pressure in the second gas storage unit 20 is below a specified value, the gas generator can be activated to supply gas to the second gas storage unit 20, as shown in Figure 1. Alternatively, the first gas storage unit 9 can be opened to supply gas to the second gas storage unit 20, as shown in Figure 2.
[0044] In this example, since the gas pressure in the second gas storage unit 20 is lower than that in the first gas storage unit 9, the first gas storage unit 9 can also supply gas to the second gas storage unit 20. Compared to the method in which the air compressor 4 supplies gas to the second gas storage unit 20, the larger volume of the first gas storage unit 9 allows for a timely supply of gas to the second gas storage unit 20, thus avoiding problems such as the gas generation unit frequently switching on and off, and the inability to supply sufficient gas in a short time. In the example shown in Figures 1 and 2, the first pipeline 100 includes a pipeline connecting the air compressor 4 and the suspension device, and a pipeline connecting the first gas storage unit 9 and the suspension device.
[0045] In other examples, the gas generation unit may be, but is not limited to, an air compressor 4, a nitrogen compressor, an inert gas compressor, or a gas storage unit. Alternatively, the gas generation unit may be a nitrogen generator. The nitrogen generator is configured to prepare nitrogen. The gas generation unit may further include a nitrogen generator and a nitrogen compressor. The nitrogen compressor is configured to pressurize the nitrogen prepared by the nitrogen generator and to supply the pressurized nitrogen to a seat adjustment device or suspension device.
[0046] In one embodiment, as shown in Figure 1, the first gas containment device is a suspension device. The second gas containment device is a seat adjustment device. A gas supply device supplies gas to the first gas containment device via a first pipeline 100. The gas supply device supplies gas to the second gas containment device via a second pipeline 200. A distribution valve is located between the first gas storage unit and the suspension device.
[0047] The distribution valve 7 is configured to control the opening and closing of the suspension system and the first gas storage unit 9. For example, the suspension system includes a plurality of air springs 6, such as four air springs. The distribution valve 7 comprises four air spring solenoid valves 5 corresponding to the air springs 6 and a gas storage unit solenoid valve 8 corresponding to the first gas storage unit 9. When the vehicle body is raised, the air spring solenoid valves 5 and the gas storage unit solenoid valve 8 open, and the high-pressure gas in the first gas storage unit 9 flows into the four air springs 6, raising the height of the vehicle body. When it is necessary to lower the vehicle body, the gas storage unit solenoid valve 8 closes, and the gas in the air springs 6 is discharged outside the vehicle compartment. The vehicle compartment is, for example, the driver's cab or the luggage compartment.
[0048] In one example, the pressure limiting valve set is located between the second gas storage unit 20 and the seat adjustment device. The pressure limiting valve set is located in the second pipeline 200. The pressure limiting valve set can control the gas pressure in the second pipeline 200 located downstream of the pressure limiting valve set to meet the operating requirements of the seat adjustment device.
[0049] In one example, as shown in Figure 1, the pressure limiting valve set includes a first pressure limiting valve 19 and a second pressure limiting valve 18. The first pressure limiting valve 19 is located in a second pipeline 200, which includes an exhaust branch pipe. The second pressure limiting valve 18 is located in the exhaust branch pipe.
[0050] In this example, the gas pressure in the second gas storage unit 20 is higher than the operating pressure of the seat adjustment device. To match the operating pressure of the seat adjustment device, the first pressure limiting valve 19 is located in the second conduit 200. Those skilled in the art can select the specifications of the first pressure limiting valve 19 according to the gas pressure in the second gas storage unit 20 and the operating pressure of the seat adjustment device. The exhaust branch pipe is configured to discharge the gas in the second conduit 200. For example, the second pressure limiting valve 18 is a solenoid valve or a gas valve. During exhaust of the second conduit 200, the second pressure limiting valve 18 opens, resulting in the rapid discharge of gas from the airbag. Placing the second pressure limiting valve 18 in the second conduit 200 to discharge gas can enable faster gas discharge.
[0051] In addition, the arrangement of the exhaust branch pipe and the second pressure limiting valve 18 allows for the pressure reduction of the high-pressure gas via the second pressure limiting valve 18 when the first pressure limiting valve 19 is unusable, thereby preventing damage to the seat adjustment device due to excessive gas pressure.
[0052] In one example, a gas pressure regulating valve set is provided in the second conduit 200. The gas pressure regulating valve set is configured to regulate the gas pressure of the seat adjustment device. The seat adjustment device includes an airbag. The inflation, deflation, and maintenance of the gas pressure of the airbag are controlled by the gas pressure regulating valve set.
[0053] In one example, the gas pressure regulating valve set 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 a gas supply device. The second end is connected to a seat adjustment device. The third end is connected to a first exhaust pipe. The second valve is located in the first exhaust pipe and controls the opening and closing of the first exhaust pipe. Two of the first, second, and third ends are selectively in communication.
[0054] The first valve and the second valve may be solenoid valves, gas pressure valves, etc. As shown in Figure 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 an adjustment mechanism for the driver's seat and an adjustment mechanism for the passenger seat. The second pipeline 200 is provided with a driver's seat control valve 15 and a passenger seat control valve 16, which control the gas passages of the driver's seat adjustment mechanism and the passenger seat adjustment mechanism, respectively. Of course, the driver's seat control valve 15 and the passenger seat control valve 16 may be omitted in order to simplify the seat adjustment device.
[0055] Both the driver's seat adjustment mechanism and the passenger seat adjustment mechanism are equipped with airbags. For example, the airbags include a left-side airbag 12 corresponding to the left side of the seat and a right-side airbag corresponding to the right side of the seat. The left-side airbag 12 and the right-side airbag reduce the tilt of the passenger's body by adjusting the angle and height of the left and right sides of the seat, respectively.
[0056] As an example for explanation, the left-side airbag 12 of the driver's seat adjustment mechanism is used. When the vehicle turns right, the passenger leans to the left. In this case, the driver's seat control valve 15 and the intake solenoid valve 10 open, and the exhaust solenoid valve 13 closes. The high-pressure gas in the second gas storage unit 20 reaches the left-side airbag 12 via the first pressure limiting valve 19, the driver's seat control valve 15, and the intake solenoid valve 10. The left-side airbag 12 inflates and then deploys, changing the angle to the left to support the passenger and reducing the passenger's tilt to the left. When the gas pressure in the left-side airbag 12 reaches a specified value, the intake solenoid valve 10 closes, and the gas pressure in the left-side airbag 12 is maintained. When the vehicle transitions to straight driving, the driver returns to an upright seated position. In this case, the exhaust solenoid valve 13 opens, releasing the gas in the left-side airbag 12, causing the left-side airbag 12 to deflate and return to its initial state.
[0057] In this example, this structure of the first valve simplifies the method of connecting the second valve, which is convenient for assembling and disassembling the seat adjustment device.
[0058] In one example, as shown in Figure 1, the gas generation unit is connected to a first pipeline 100, and the gas generation unit is connected to a second gas storage unit via a third pipeline 300.
[0059] Furthermore, it includes a connecting pipe 41 that connects the first pipe 100 and the third pipe 300. A connecting valve 42 is provided in the connecting pipe 41. The first gas storage unit 9 supplies gas to the second gas storage unit 20 via the first pipe 100, the connecting pipe 41, and the third pipe 300.
[0060] In this example, the first conduit 100 and the third conduit 300 are separated by a gas generation unit such as an air compressor 4. The second conduit 200 and the third conduit 300 are separated by a second gas storage unit 20. As shown in Figure 1, the gas outlet of the gas generation unit is connected to the first conduit 100. The gas generation unit can supply gas to the suspension device and the first gas storage unit 9 via the first conduit 100. The third conduit 300 is configured to supply gas to the second gas storage unit 20 and to discharge gas from the suspension device and the like.
[0061] The connecting pipeline 41 connects the first pipeline 100 and the third pipeline 300. This allows exhaust from the suspension system and supply of air from the first gas storage unit 9 to the second gas storage unit 20 to bypass the air compressor 4. A connecting valve 42 is provided in the connecting pipeline 41. The connecting valve 42 is either an electric valve or a pneumatic valve. The connecting valve 42 controls the opening and closing of the connecting pipeline 41. When the first gas storage unit 9 supplies gas to the second gas storage unit 20, the first gas storage unit 9 supplies gas to the second gas storage unit 20 via the first pipeline 100, the connecting pipeline 41, and the third pipeline 300.
[0062] In one example, the third conduit 300 is connected to the second exhaust conduit. The suspension system discharges gas through the first conduit 100, the connecting conduit 41, the third conduit 300, and the second exhaust conduit.
[0063] For example, the second exhaust line is a branch pipe connected to the third line 300, and a gas relief valve 3 is provided in the second exhaust line. The gas relief valve 3 is either an electrically operated valve or a pneumatic valve. Exhaust is controlled by opening the gas relief valve 3.
[0064] In one example, the second exhaust line is connected to the suspension system. The exhaust port of the second exhaust line is adapted to discharge gas outside the vehicle.
[0065] Alternatively, the second exhaust line may be directly connected to the suspension system. Alternatively, the second exhaust line may be indirectly connected to the suspension system. For example, the aforementioned suspension system is connected to the second exhaust line via the first line 100, the connecting line 41 and the third line 300.
[0066] For example, as shown in Figure 1, the third pipeline 300 is connected to the second exhaust pipeline. A gas relief valve 3 is provided in the second exhaust pipeline. The gas relief valve 3 is located outside the driver's cab. The gas relief valve 3 is an electromagnetic valve or a pneumatic valve, etc. The gas relief valve 3 can discharge gas emitted from the suspension system to the outside. The gas emitted from the suspension system reaches the second exhaust pipeline via the first pipeline 100, the connecting pipeline 41, and the third pipeline 300, and is then discharged outside the driver's cab via the second exhaust pipeline, thus preventing adverse effects on the gas environment in the driver's cab.
[0067] In one example, as shown in Figure 1, an intake pipe is further included. The intake pipe is used for intake of the gas generation unit. The intake pipe is connected to a third conduit 300. The third conduit 300 is connected to the intake port of an air compressor. A first one-way valve 2 is provided in the intake pipe. The first one-way valve 2 is configured to allow gas to flow into the gas generation unit.
[0068] For example, the intake pipe is used for intake of the air compressor 4. The gas reaches the air compressor 4 via the intake pipe and a portion of the third pipeline 300. After being pressurized in the air compressor 4, the gas is supplied to the suspension device or the first gas storage unit 9 via the first pipeline 100.
[0069] In another example, as shown in Figure 2, after being pressurized by the air compressor 4, the gas is supplied to the suspension device or the first gas storage unit 9 via the first pipeline 100 and reaches the second gas storage unit 20 via the third pipeline 300.
[0070] In one example, the intake port of the air intake pipe is located inside the vehicle compartment. This compartment could be, for example, the driver's cab or the luggage compartment.
[0071] In this example, the gas compressed by the air compressor 4 enters the air compressor 4 through the intake pipe. In this example, the intake port of the intake pipe is located inside the vehicle. Under normal circumstances, the external environment of a vehicle is complex. For example, the air in the external environment has unstable quality, such as a high dust content, high humidity, or a high content of toxic or harmful substances. If the intake port of the intake pipe is located outside the vehicle, it may damage the air compressor 4, air spring 6, and airbags.
[0072] However, the air inside the vehicle is normally filtered by the vehicle's air filter, resulting in stable air quality and low concentrations of harmful components. In this example, by positioning the intake port of the intake manifold inside the vehicle, it is possible to prevent damage to the air compressor 4, suspension system, airbags, and first gas storage unit 9 due to poor gas quality.
[0073] A filter is provided in the intake manifold. The filter can filter the air inside the vehicle cabin, thereby maintaining good quality air flowing into the air compressor 4.
[0074] As shown in Figure 1, a first one-way valve 2 is provided in the intake pipe. The arrangement of the first one-way valve 2 and the second one-way valve 1 allows for automatic adjustment of the intake and exhaust of the integrated control system.
[0075] In one example, as shown in Figure 1, a second one-way valve 1 is provided in the third pipeline 300. The second one-way valve 1 is configured to allow gas to flow into the second gas storage unit 20.
[0076] In this example, the second one-way valve 1 allows gas to flow into the second gas storage unit 20, but prevents the gas in the second gas storage unit 20 from flowing into the air compressor 4, the suspension device, or the first gas storage unit 9. This effectively prevents the gas in the second gas storage unit 20 from being discharged when the gas relief valve 3 is opened.
[0077] During intake, the external atmospheric pressure is higher than the gas pressure in the third conduit 300. In this case, due to the pressure difference, the first one-way valve 2 opens automatically, and the second one-way valve 1 remains closed because the directionality and pressure difference of the second one-way valve do not meet the opening conditions. Gas flows into the air compressor 4 via the intake pipe and the third conduit 300. When gas is supplied to the second gas storage unit 20, the gas pressure upstream of the second one-way valve 1 is higher than the gas pressure downstream of the second one-way valve 1. Due to the pressure difference, the second one-way valve 1 opens automatically, and the first one-way valve 2 remains closed because the directionality and pressure difference of the first one-way valve do not meet the opening conditions. Gas flows into the second gas storage unit 20 via the intake pipe and the third conduit 300. This configuration simplifies the piping design of the air compressor 4.
[0078] In one example, as shown in Figure 1, the suspension system includes multiple air springs 6, and each of the multiple air springs 6 is separately connected to a gas supply device.
[0079] Multiple air springs 6 are distributed at different positions on the vehicle body. For example, the position of the air springs 6 corresponds to the position of the wheels. This allows for smoother and more uniform height adjustment of the vehicle body. The intake, exhaust, and pressure maintenance of each air spring 6 are controlled by the air spring solenoid valve 5. The gas storage unit solenoid valve 8 is configured to control the intake, exhaust, and pressure maintenance of the first gas storage unit 9.
[0080] When the first gas storage unit 9 expands, the air compressor 4 turns on, the communication valve 42 and the multiple air spring solenoid valves 5 close, the gas storage unit solenoid valve 8 opens, and gas flows into the air compressor 4 through the intake pipe and part of the third pipeline 300. The gas compressed by the air compressor 4 is then transferred to the first gas storage unit 9 through the first pipeline 100.
[0081] When the gas pressure in the first gas storage unit 9 reaches the first specified gas pressure, the gas storage unit solenoid valve 8 closes, the air compressor 4 turns off, and as a result, the gas pressure in the first gas storage unit 9 is maintained.
[0082] When it is necessary to increase the height of the vehicle body, the communication valve 42 closes, the air spring solenoid valve 5 and the gas storage unit solenoid valve 8 open, and the high-pressure gas in the first gas storage unit 9 flows into the air spring 6 via the first pipeline 100, thereby increasing the height of the vehicle body.
[0083] If it is necessary to lower the height of the vehicle body, the gas storage unit solenoid valve 8 closes, the air spring solenoid valve 5 and the communication valve 42 open, and the air in the air spring 6 is discharged through the first pipeline 100, the communication pipeline 41, a portion of the third pipeline 300, and the second exhaust pipeline.
[0084] The suspension system is more integrated and easier to install and remove because multiple air spring solenoid valves 5 and gas storage unit solenoid valves 8 form an assembly.
[0085] In one example, as shown in Figure 1, the second gas storage unit 20 is connected to the first gas storage unit 9, and the gas pressure in the second gas storage unit 20 is lower than the gas pressure in the first gas storage unit 9.
[0086] In this example, since the gas pressure in the second gas storage unit 20 is lower than that in the first gas storage unit 9, gas can be supplied from the first gas storage unit 9 to the second gas storage unit 20. Compared to the method in which the air compressor 4 supplies gas to the second gas storage unit 20, the first gas storage unit 9 has a larger volume, so it can supply gas to the second gas storage unit 20 in a timely manner, avoiding the problems of the air compressor 4 frequently turning on and off, and the inability to supply enough gas in a short time.
[0087] As shown in Figure 1, the second gas storage unit 20 is connected to the first gas storage unit 9 via the third pipeline 300, the connecting pipeline 41, and the first pipeline 100. This connection method utilizes existing pipelines, and the first gas storage unit 9 can supply gas to the second gas storage unit 20 simply by controlling the opening and closing of valves.
[0088] In one example, as shown in Figure 1, the first gas storage unit 9 supplies gas to the second gas storage unit 20 via the first pipeline 100, the connecting pipeline 41, and the third pipeline 300. In this example, the connecting pipeline crosses the air compressor 4 and connects the first pipeline 100 and the third pipeline 300. This prevents gas from flowing into the air compressor 4. When the first gas storage unit 9 supplies gas to the second gas storage unit 20, the air compressor stops supplying gas to the first pipeline 100.
[0089] In one example, as shown in Figure 1, the gas storage unit solenoid valve 8 and communication valve 42 are configured to open when the gas pressure in the second gas storage unit 20 is below a specified value.
[0090] In this way, the gas storage unit solenoid valve and communication valve 42 can effectively control the first gas storage unit 9 and supply gas to the second gas storage unit 20.
[0091] In one example, as shown in Figure 1, a first pressure sensor 14 is provided in the second pipeline 200. The first pressure sensor 14 is configured to detect the gas pressure of the second gas storage unit 20.
[0092] If the gas pressure in the second gas storage unit 20 is less than the second specified gas pressure, the air compressor 4 or the first gas storage unit 9 supplies gas to the second gas storage unit 20.
[0093] In one example, the integrated adjustment system further includes a control device. The control device is configured to control the expansion, exhaust, and gas pressure maintenance of the suspension device, the first gas storage unit 9, and the seat adjustment device.
[0094] For example, the control device may be a vehicle controller or a dedicated controller for an integrated adjustment device. The control device can control the opening and closing of the air spring solenoid valve 5, the gas storage unit solenoid valve 8, the intake solenoid valve 10, the exhaust solenoid valve 13, the communication valve 42, the gas relief valve 3, and the second pressure limiting valve 18.
[0095] In one example, the gas supply device includes a backup interface. The backup interface is configured to connect to other devices other than the first and second gas containment devices. For example, the other devices may be, but are not limited to, an external dust removal device or an air pump. In this example, the backup interface can supply gas to the other devices, thereby meeting the demands for various gas uses.
[0096] According to another embodiment of the present application, an integrated adjustment system is provided. The system includes a suspension device, a seat adjustment device, and a gas supply device, the gas supply device being connected to the suspension device and supplying gas to the suspension device, and the gas supply device being connected to the seat adjustment device and supplying gas to the seat adjustment device.
[0097] In this example, the aforementioned gas supply device can be used. The seat adjustment device is configured to adjust the sides of the seat to adjust the passenger's posture when the vehicle turns, reducing passenger tilt and improving the driving experience. The suspension device is configured to adjust the vehicle height according to road conditions, ensure vehicle passability, and reduce the vehicle's wind resistance.
[0098] In this example, the seat adjustment system and the suspension system share a single gas supply unit, significantly reducing the overall size of the integrated adjustment system, saving interior space in the vehicle, and lowering the vehicle's cost.
[0099] In addition, the suspension system is used far less frequently than the seat adjustment system. The integrated adjustment system can ensure a high frequency of use of the gas supply system, thereby avoiding unnecessary losses of the gas supply system due to prolonged downtime.
[0100] In addition, the suspension system typically adjusts the vehicle's height when the vehicle is stationary and adjusts the vehicle's height in accordance with changes in vehicle speed when the vehicle is moving straight. The seat adjustment system is typically used when the vehicle is turning. Therefore, the functions of the suspension system and the seat adjustment system do not overlap in terms of usage time, and as a result, the gas supply system can be utilized to its fullest potential.
[0101] In addition, since the operation of both the suspension system and the seat adjustment system is related to the vehicle's motion state, in the case of the suspension system and the seat adjustment system, coordinated control of multiple functional modules (e.g., multiple solenoid valves or pressure sensors) can be achieved through a single control unit. As a result, the resources of the control unit can be more appropriately scheduled, and the control strategy can be more appropriately adjusted.
[0102] In addition, in the case of suspension and seat adjustment devices, both devices are triggered and controlled based on the vehicle's position and acceleration state, so the vehicle signal needs to be sent only once rather than multiple times. This saves computational resources for the overall vehicle control system and improves the overall system's operational efficiency.
[0103] In addition, because the two systems can be controlled by a single control unit, for example, the functions of the seat adjustment device can be integrated into the control unit of the suspension system, eliminating the need for two separate control units and thus reducing vehicle costs.
[0104] In one example, the system further includes a tire inflator. A gas supply device is connected to the tire inflator and supplies gas to it.
[0105] The tire inflation device is as described above. For example, the gas supply device supplies gas to the tire inflation device via a fourth conduit, or the tire inflation device is connected to at least one of the first conduit 100, the second conduit 200, and the third conduit 300. In this example, the suspension device, tire inflation device, and seat adjustment device share a single gas supply device, thereby reducing the size of the integrated adjustment system, saving internal space in the vehicle, and lowering the cost of the vehicle.
[0106] A third embodiment of this application provides a vehicle, which includes the aforementioned integrated adjustment system.
[0107] This vehicle features high integration, allowing for adjustment of the vehicle's height and seat height.
[0108] (1) Adjustment of vehicle height when stationary: The height of the vehicle is automatically adjusted according to the passengers inside the vehicle or the mass of the vehicle, and is used to maintain the height necessary for driving the vehicle and the stability of the vehicle's running condition. The adjustment of the vehicle height may be performed on the air springs 6 corresponding to all wheels of the vehicle, or it may be performed on the air springs 6 corresponding to only one wheel.
[0109] The operating conditions for height adjustment using the air springs 6 corresponding to all wheels of the vehicle are as follows: 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 in the distribution valve 7 and the gas storage unit solenoid valve 8 corresponding to the first gas storage unit 9 are opened, allowing the high-pressure gas in the first gas storage unit 9 to flow into the four air springs 6, thereby raising the height of the vehicle body. When it is necessary to lower the vehicle body, the gas storage unit solenoid valve 8 is closed. The communication valve 42 is opened, and the air in the air springs 6 is discharged outside the driver's cab via the gas relief valve 3.
[0110] The operating conditions for height adjustment applied to the air spring 6 corresponding to one wheel are as follows: Open the air spring solenoid valve 5 and the gas storage unit solenoid valve 8 corresponding to the wheel to be lifted. In this case, the high-pressure gas in the first gas storage unit 9 flows into the air spring 6 corresponding to the air spring solenoid valve 5, and as the air spring 6 extends, the part of the vehicle body corresponding to the wheel is lifted. If it is necessary to lower the vehicle body, close the gas storage unit solenoid valve 8. Open the communication valve 42 and discharge the air in the air spring 6 to the outside of the driver's cab via the air spring solenoid valve 5, the communication valve 42, and the gas relief valve 3.
[0111] (2) Control of vehicle height during driving: Used to improve the directional stability of the vehicle during high-speed driving. When the controller determines that the speed of the vehicle traveling in a straight line has reached or exceeded a specified speed, a control signal is sent to increase the damping force of the electronically controlled shock absorber. At the same time, the distribution valve 7 is controlled to discharge the gas in the air spring 6 and lower the height of the vehicle, thereby reducing wind resistance, lowering the center of gravity of the vehicle, and improving handling stability during high-speed driving. In this case, the communication valve 42 and all air spring solenoid valves 5 are opened, and the air in the air spring 6 is discharged to the outside of the driver's cab via the air spring solenoid valves 5, communication valve 42 and gas relief valve 3 to lower the height of the vehicle.
[0112] If the speed of a vehicle traveling straight falls below the specified speed, the communication valve 42 is closed, the gas storage unit solenoid valve 8 and all air spring solenoid valves 5 are opened, and the four air springs 6 are reinflated to raise the height of the vehicle.
[0113] (3) Overload protection for the suspension system: The maximum allowable air pressure for the suspension system is set in the ECU. If the air pressure of the air spring 6 exceeds the maximum allowable air pressure, the air spring 6 will contract and the height of the vehicle will decrease. In this case, the communication valve 42 and all air spring solenoid valves 5 will open, and the air inside the air spring 6 will be discharged to the outside of the driver's cab via the air spring solenoid valves 5, the communication valve 42 and the gas relief valve 3, thereby lowering the height of the vehicle.
[0114] If the vehicle needs to return to its normal state, for example, if the air pressure of the air spring 6 is higher than the maximum allowable air pressure, the load on the vehicle, such as unloading an overloaded load, needs to be reduced. If the air pressure of the air spring 6 is lower than the maximum allowable air pressure, the vehicle will restart, and then the vehicle will return to its normal state.
[0115] (4) Side steering support of the seat: Used to improve the lateral stability of the passenger relative to the seat when the vehicle body is subjected to lateral forces. When the vehicle turns, for example, if at least one of the lateral acceleration, roll angle, or roll angular velocity is above a specified value, the driver's seat control valve 15 and the corresponding intake solenoid valve 10 open and the exhaust solenoid valve 13 close. The high-pressure gas in the second gas storage unit 20 flows into the airbags, such as the left airbag 12, via the first pressure limiting valve 19, the driver's seat control valve 15, and the corresponding intake solenoid valve 10, supporting the passenger's waist and preventing the passenger from tilting. If at least one of the vehicle's lateral acceleration, roll angle, or roll angular velocity is below a specified value, the intake solenoid valve 10 closes and the exhaust solenoid valve 13 opens, discharging the gas in the airbag (such as the left airbag 12) to the outside of the driver's seat, and it ceases to support the left side of the seat.
[0116] Note that in each of the aforementioned operating modes, the opening and closing of different valves are controlled by the controller. When the suspension device is operating, the first gas storage unit 9 supplies gas only to the suspension device and stops supplying gas to the seat adjustment device. When the seat adjustment device is operating, the second gas storage unit 20 supplies gas only to the seat adjustment device, and the first gas storage unit 9 or the air compressor 4 stops supplying gas to the second gas storage unit 20.
[0117] A vehicle is provided according to a fourth embodiment of the present application. The vehicle includes the aforementioned integrated adjustment system. A first pressure limiting valve 19 is provided in the second conduit 200. The seat adjustment device includes an airbag. The airbag is located at the rear side of the seat. The airbag is connected to the second conduit 200. A first valve and a second valve are provided in the second conduit 200. The first valve can control the intake of the airbag. The second valve is configured to control the exhaust of the airbag.
[0118] The first pressure limiting valve 19 and the first valve are configured to open when they receive a signal indicating that the vehicle is turning, and to inflate the airbag located at the rear side of the inclined side.
[0119] In this example, the first valve is an intake solenoid valve 10, and the second valve is an exhaust solenoid valve 13. When the vehicle turns right, the passenger's body leans to the left. After receiving the signal to turn right, the controller sends a control signal, which causes the driver's seat control valve 15 and the corresponding intake solenoid valve 10 to open and the exhaust solenoid valve 13 to close. The high-pressure gas in the second gas storage unit 20 flows through the first pressure limiting valve 19, the driver's seat control valve 15, and the corresponding intake solenoid valve 10 into airbags such as the left-side airbag 12, supporting the passenger's waist and preventing the passenger from leaning. In one example, the second valve is configured to open when it receives a signal that the vehicle is no longer turning. For example, when the controller receives a signal that the vehicle is going straight or stopped, it sends a control signal to open the exhaust solenoid valve 13, expelling the gas in the left-side airbag 12, and the left side returns to its initial state.
[0120] The signal includes at least one of the following: lateral acceleration, roll angle, or roll angular velocity. These signals enable the controller to accurately determine the vehicle's state and precisely control the operation of the integrated adjustment system.
