[0084] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative effort fall within the protection scope of the present application.

[0085] According to a first aspect of the present application, referring to Figures 1 to 4 The present application provides an adjusting system 100 for adjusting the pressure distribution of a seat 300 of a vehicle 10; the adjusting system 100 comprises a pressure supply device 110 and adjusting units 120.

[0086] The pressure supply device 110 is used for providing a pressure-transferring medium; the adjusting units 120 are provided in plurality and are respectively arranged in a plurality of preset areas of the seat 300 and have adjusting cavities, that is, at least one adjusting unit 120 is arranged in each preset area.

[0087] It can be understood that the plurality of preset areas are arranged in a same module area of the seat 300, which can be a cushion, a backrest, a side wing, etc., and correspondingly, the plurality of adjusting units 120 constitute a whole and are arranged in the module area; or, the plurality of preset areas are arranged in different module areas.

[0088] The plurality of adjusting units 120 are respectively communicated to the pressure supply device 110, so that the pressure supply device 110 and the adjusting cavities exchange the medium to change the pressure distribution of the seat 300.

[0089] It can be understood that the adjusting unit 120 at least adopts a flexible and stretchable material, and through the medium exchange between the pressure supply device 110 and the adjusting cavities, the filling amount of the medium in the adjusting cavities can be changed, so that the plurality of preset areas of the seat 300 present corresponding pressure distributions.

[0090] Through the above technical solution, by arranging the plurality of adjusting units 120 in the plurality of preset positions of the seat 300 and changing the pressure distribution of the seat 300 through the medium exchange between the pressure supply device 110 and the adjusting units 120, the seat 300 can better fit the user's body, thereby improving the riding comfort.

[0091] In some embodiments, referring to Figure 1 and Figure 2 The pressure supply device 110 is in communication with the suspension system 200 of the vehicle 10.

[0092] Specifically, the suspension system 200 of the vehicle 10 includes actuators 210 such as shock absorbers and medium springs (oil-gas springs or air springs), and the like, and the pressure supply device 110 is in communication with at least one pressure chamber (such as compression chambers and rebound chambers of shock absorbers, and the like) of the suspension system 200, and by changing the amount of medium in the pressure chamber, the stiffness and damping of the suspension are adjusted.

[0093] With such a scheme, by adjusting the system 100 to share the pressure supply device 110 with the suspension system 200, the adjusting system 100 of the present application does not need to be provided with a separate pressure supply device 110, thereby being able to improve the space utilization of the vehicle 10 and reduce costs, and the adjusting system 100 and the suspension system 200 have better linkage effects.

[0094] In some embodiments, referring to Figures 1 to 3 The pressure supply device 110 includes a control pump 111. The control pump 111 is configured to deliver medium to the adjusting unit 120 at a first type of pressure.

[0095] Optionally, the control pump 111 includes one of a gear pump, a plunger pump, a vane pump, and a screw pump, and the like.

[0096] In some embodiments, referring to Figures 1 to 4 The adjusting system 100 further includes a first switching device 130 and a controller 140.

[0097] The first switching device 130 is connected between the control pump 111 and the adjusting unit 120 by a pipeline, and is used to control the communication between the control pump 111 and the adjusting unit 120; the controller 140 is electrically connected to the first switching device 130, and is configured to control the action of the first switching device 130.

[0098] With such a scheme, by the controller 140 controlling the first switching device 130, the medium exchange between the adjusting unit 120 and the control pump 111 is realized.

[0099] Optionally, the controller 140 can be a vehicle 10 controller 140 or an independent controller 140.

[0100] As an optional scheme, the controller 140 is electrically connected to the control pump 111, and is configured to regulate the working state of the control pump 111.

[0101] In some embodiments, referring to Figures 1 to 4The first switch device 130 includes a plurality of first sub-switch units. Each first sub-switch unit is configured to control at least one adjusting unit 120, i.e., each first sub-switch unit is connected to at least one adjusting unit 120 through a pipeline. The plurality of first sub-switch units are electrically connected to the controller 140, so that independent charging and discharging control of each adjusting unit 120 can be achieved.

[0102] For example, the first switch device 130 is a multi-connection electromagnetic valve, which has a function of converting one-way into multi-way, and each first sub-switch unit is a controllable path.

[0103] It should be noted that the electromagnetic valve in the present application can be a normally closed electromagnetic valve, i.e., conducting when powered on and blocking when powered off.

[0104] In some embodiments, the controller 140 is further configured to cause the first switch device 130 to have a first working mode, and the plurality of first sub-switch units are caused to act synchronously when the first switch device 130 is in the first working mode.

[0105] Specifically, when the first switch device 130 is in the first working mode, each first sub-switch unit is uniformly closed or opened.

[0106] With such a scheme, overall adjustment of the plurality of adjusting units 120 can be achieved, and the adjustment efficiency is improved.

[0107] In some embodiments, the controller 140 is further configured to cause the first switch device 130 to have a second working mode. In the second working mode, the plurality of first sub-switch units are caused to act independently.

[0108] Specifically, when the first switch device 130 is in the second working mode, each first sub-switch unit is controlled to be closed or opened independently, so that the charging and discharging of the medium of each adjusting unit 120 can be controlled independently.

[0109] With such a scheme, each first sub-switch unit works independently to achieve independent control of each adjusting unit 120, so that the plurality of preset regions of the seat 300 have different pressure distributions, and the whole formed by the plurality of adjusting units 120 can better fit the human body curve, thereby improving the riding comfort of the seat 300.

[0110] In some embodiments, with reference to Figures 1 to 4 The pressure supply device 110 includes an accumulator 112. The accumulator 112 is configured to deliver the medium to the adjusting unit 120 at the second type of pressure.

[0111] It can be understood that the second type of pressure is different from the first type of pressure, and compared with the control pump 111, the accumulator 112 can quickly release the stored energy, so as to provide the medium for the adjusting unit 120 in the working condition requiring rapid adjustment of the pressure distribution.

[0112] Specifically, the accumulator 112 is a tank container capable of storing hydraulic energy, and can quickly deliver the medium to the adjusting unit 120 in a specific case.

[0113] Optionally, the accumulator 112 includes one of a spring accumulator 112, a heavy hammer accumulator 112, and a gas accumulator 112.

[0114] As a specific solution, referring to Figures 1 to 4 , the control pump 111 is connected to the accumulator 112 through a pipeline, so that the control pump 111 can provide the medium for the accumulator 112. The adjusting system 100 further includes a third switching device 160. The third switching device 160 is connected between the control pump 111 and the accumulator 112, and is used to control the communication between the accumulator 112 and the control pump 111.

[0115] Specifically, the third switching device 160 adopts a single-way electromagnetic valve.

[0116] In some embodiments, referring to Figure 1 , the adjusting system 100 further includes a second switching device 150. The second switching device 150 is connected between the accumulator 112 and the adjusting unit 120, and is used to control the communication between the accumulator 112 and the adjusting unit 120. The controller 140 is electrically connected to the second switching device 150, and is configured to control the action of the second switching device 150.

[0117] With such a solution, the medium exchange between the adjusting unit 120 and the accumulator 112 is realized by the control of the second switching device 150 by the controller 140.

[0118] In some embodiments, the second switching device 150 includes a plurality of second sub-switching units. The second sub-switching units are configured to control at least one adjusting unit 120, that is, each second sub-switching unit is connected to at least one adjusting unit 120 through a pipeline. The plurality of second sub-switching units are electrically connected to the controller 140, so that the independent oil charging and discharging control of each adjusting unit 120 can be realized.

[0119] Exemplarily, the second switching device 150 is a multiple-way electromagnetic valve, has a function of converting one way into multiple ways, and each second sub-switching unit serves as one way and can be controlled individually.

[0120] In some embodiments, the controller 140 is further configured to cause the second switching device 150 to have a third working mode; and the second switching device 150 is caused to operate in the third working mode to make the plurality of second sub-switching units operate independently.

[0121] Specifically, when the second switching device 150 operates in the third working mode, each second sub-switching unit is controlled to be closed or opened, so that the medium can be independently provided to the medium of each adjusting unit 120.

[0122] With such a scheme, each second sub-switching unit operates independently to achieve independent control of each adjusting unit 120, so that the plurality of preset regions of the seat 300 have different pressure distributions, and the whole of the plurality of adjusting units 120 can better fit the human body curve, thereby improving the ride comfort of the seat 300, and the medium is delivered to the adjusting unit 120 by the accumulator 112, the adjustment is rapid, and better dynamic comfort is provided.

[0123] In some embodiments, referring to Figure 2 and Figures 1 to 4 , the adjusting unit 120 is respectively connected with the first sub-switching unit and the second sub-switching unit. The controller 140 is further configured to cause the first switching device 130 and the second switching device 150 to have a third working mode.

[0124] When the first switching device 130 and the second switching device 150 are in the third working mode, the second sub-switching unit can be opened to make the accumulator 112 deliver the medium to the adjusting unit 120, that is, to increase the pressure of the adjusting unit 120.

[0125] When the first switching device 130 and the second switching device 150 are in the third working mode, the first sub-switching unit can also be opened to make the medium in the adjusting unit 120 output through the first sub-switching unit, that is, to reduce the pressure of the adjusting unit 120.

[0126] In some embodiments, the controller 140 is configured to control the first switching device 130 and the second switching device 150 according to the current information of the vehicle, so that the first switching device 130 and the second switching device 150 selectively operate.

[0127] Specifically, the current information of the vehicle includes one or more of vehicle motion information, road condition information, and human body pressure distribution information.

[0128] The controller 140 integrates an intelligent control algorithm for reading vehicle motion information, road condition information, navigation map information, human body pressure distribution information, etc., and calculating the amount of medium in each adjusting unit 120 in real time according to the above information, and then realizing the charging and discharging of the medium by controlling the opening and closing of the above control pump 111, first switching device 130 and second switching device 150, and realizing the zoned control adjustment of the pressure distribution of the seat 300.

[0129] Exemplarily, the proportion of the medium in each adjusting unit 120 can be adaptively adjusted according to the human body pressure distribution information, so that the human body is always in the most comfortable state, i.e., taking the ischial tuberosity as the pressure center and gradually decreasing to the surrounding. Or the vehicle running information and road condition information can be read, and the adjusting unit 120 on one side is increased with medium according to the lateral acceleration size when turning, to provide good lateral support for the driver and passenger, and the medium is appropriately reduced to make the seat cushion soft in the bumpy road section, to provide good shock absorption for the driver and passenger, so that the seat 300 has good static and dynamic comfort.

[0130] With such a scheme, by controlling the first switching device 130 and the second switching device 150 according to the current information of the vehicle, the dynamic control of the adjusting unit 120 can be quickly realized, and the adjustment speed and stability are improved.

[0131] As an optional scheme, the medium for transmitting pressure can be a liquid medium or a gas medium, which is not limited, and can be selected according to the medium used by the suspension system 200 of the vehicle 10.

[0132] As an optional scheme, the medium can be a liquid medium or a gas medium.

[0133] When the medium is a liquid medium (such as hydraulic oil), i.e., the vehicle 10 is configured with a hydraulic suspension, correspondingly, the control pump 111 is a hydraulic pump. When the medium is a gas medium, i.e., the vehicle 10 is configured with an air suspension, correspondingly, the control pump 111 is an air pump. That is, the selection of the medium depends on the suspension system 200 of the vehicle 10, and therefore, the adjusting system 100 of the present application can be adaptively configured according to the design of the suspension system 200 of the vehicle 10, and has a wide range of applications.

[0134] Since the adjustment mode of the gas medium is slow, it is difficult to realize adaptive control in combination with other systems of the whole vehicle, such as a road preview system. If a high-power air pump is used, the noise seriously affects the comfort of the driver and passenger. At the same time, the compressibility of the gas determines that the softness and hardness during the inflation process is not linear and uniform.

[0135] As a preferred scheme, the medium is a liquid medium.

[0136] With such a scheme, the adjustment of pressure distribution is realized by using the liquid medium to charge and discharge the medium for each independent adjustment unit 120 arranged in the seat 300, and the incompressibility of the liquid makes the adjustment process more stable, and the consistency of softness and shape can be maintained, so the response speed is faster and the effect is more ideal. In addition, the liquid-filled adjustment unit 120 generates little noise when charging and discharging, providing a more quiet user experience. Because the liquid can absorb and disperse impact force, the liquid can improve the shock absorption performance compared with the gas, thereby improving the comfort.

[0137] In some embodiments, with reference to Figures 1 to 4 , the adjustment system 100 further comprises a storage container 171. The storage container 171 is used to provide and / or receive the medium; the storage container 171 is connected to at least the pressure supply device 110 and the adjustment unit 120.

[0138] Specifically, the storage container 171 can provide sufficient medium for the control pump 111 to work, while receiving the medium discharged from the adjustment unit 120 and the suspension system 200.

[0139] In some embodiments, with reference to Figure 1 , the suspension system 200 further comprises a fourth switching device 220. The fourth switching device 220 is connected between the storage container 171 and the actuator 210 of the suspension system 200, and is used to control the storage container 171 and the actuator 210 of the control pump 111.

[0140] Specifically, the fourth switching device 220 adopts a single-way electromagnetic valve.

[0141] In some embodiments, with reference to Figures 1 to 4 , the adjustment system 100 further comprises a pressure detection device 181. The pressure detection device 181 is used to detect the pressure applied by the human body to the preset area, so as to obtain the human body pressure distribution information. The controller 140 is configured to control the pressure supply device 110 and the adjustment cavity to exchange the medium according to the pressure detected by the pressure detection device 181.

[0142] Exemplarily, the pressure detection device 181 can be a flexible pressure distribution sensor.

[0143] With such a scheme, by detecting the pressure applied by the human body to the preset area, the oil amount of each adjustment unit 120 can be adjusted according to the pressure distribution change, so that the seat 300 can be real-time fitted to the human body curve, and the effect of comfort adjustment can be achieved.

[0144] In some embodiments, with reference to Figure 1The adjusting system 100 further comprises a flow detection device 182. The flow detection device 182 is configured to detect the exchange flow of the adjusting unit 120. The controller 140 is configured to control the pressure supply device 110 to exchange the medium with the adjusting cavity according to the exchange flow detected by the flow detection device 182.

[0145] Specifically, the flow detection device 182 detects the exchange flow of the adjusting unit 120, and the amount of the medium in the adjusting unit 120 can be calculated based on the exchange flow, so that the controller 140 issues a corresponding control instruction to control the opening and closing of each electromagnetic valve and the pump 111.

[0146] With such a scheme, by detecting the exchange flow of the adjusting unit 120, the amount of the medium in the adjusting unit 120 is obtained. When the amount of the medium in the adjusting unit 120 reaches a set threshold, the controller 140 stops the charging and discharging control of the medium, and stops the action of charging and discharging the medium.

[0147] As a specific scheme, referring to Figures 1 to 4 The flow detection device 182 comprises a first flow sensor 182a and a second flow sensor 182b. The first flow sensor 182a is connected between the first switching device 130 and the adjusting unit 120, and is configured to detect the flow between the first switching device 130 and the adjusting unit 120. The second flow sensor 182b is connected between the second switching device 150 and the adjusting unit 120, and is configured to detect the flow between the second switching device 150 and the adjusting unit 120.

[0148] In some embodiments, referring to Figure 1 The adjusting system 100 further comprises an exchange pipeline 172. The exchange pipeline 172 is connected between the adjusting unit 120 and the pressure supply device 110. The heat exchange device 190 is configured to exchange heat with the exchange pipeline 172 to adjust the temperature of the medium in the exchange pipeline 172.

[0149] With such a scheme, by providing the heat exchange device 190, the temperature of the medium in the adjusting unit 120 is changed, and the heating and / or cooling function of the seat 300 is realized.

[0150] As a specific scheme, referring to Figure 2 and Figure 5 The heat exchange device 190 comprises a refrigeration unit 191 and a heating unit 192. The refrigeration unit 191 and the heating unit 192 each comprise a thermoelectric sheet, and each works based on the Seebeck effect and the Peltier effect. The former generates voltage through temperature difference, and the latter causes heat transfer through electric current.

[0151] The part of the exchange pipeline 172 can adopt a serpentine pipe design, the refrigeration unit 191 is arranged at one side of the serpentine pipe, the cold pole of the refrigeration unit 191 is adjacent to the serpentine pipe, and the heating unit 192 is arranged at the other side of the serpentine pipe, and the hot pole of the heating unit 192 is adjacent to the serpentine pipe.

[0152] When refrigeration is needed, the refrigeration unit 191 is powered on, when the current passes through the refrigeration unit 191, the cold pole absorbs heat and conducts the heat to the outside of the pipe, at this time, the medium in the pipe is cooled.

[0169] S140: Adjusting the seat to the specified softness based on the target state of each adjustment unit.

[0170] Specifically, the flow detection device monitors the oil quantity in the adjustment unit in real time, and when the oil quantity reaches the set threshold, the controller no longer controls the first switching device and the control pump, and the oil charging and discharging action is stopped.

[0171] In the manual adjustment mode, the second switching device is always in a closed state, and each first sub-switching unit in the first switching device is in a unified opening and closing state, that is, the manual adjustment mode is the overall adjustment of the softness.

[0172] The adaptive adjustment mode includes the following main steps:

[0173] S210: The controller acquires the current vehicle information in real time.

[0174] Specifically, the current vehicle information includes vehicle motion information, road condition information, and human body pressure distribution information, etc.

[0175] S220: Determining whether rapid adjustment is needed according to the current vehicle information.

[0176] S231: When rapid adjustment is needed, the controller controls the control pump to be closed, and the first and second switching devices to act.

[0177] Specifically, step S231 can be understood as the third working mode described above.

[0178] Exemplarily, for high-speed road conditions, the amount of oil that each adjusting unit should obtain is calculated according to the pressure distribution information according to the corresponding control algorithm, and the seat is quickly adjusted, at this time, part of the second sub-switch units in the second switch device are opened to realize the rapid oil filling of the accumulator to the adjusting unit, and the first switch device is responsible for oil discharge;

[0179] S232: When fast adjustment is not required, the controller controls the control pump to open and the first switch device to act;

[0180] Specifically, step S232 can be understood as the second working mode described above.

[0181] Exemplarily, for low-speed road conditions, fast adjustment is not required, and the second switch device is always kept in a closed state, and the control of the oil filling and discharging of each adjusting unit is controlled by the control pump and the first switch device.

[0182] S240: Adjusting the softness and hardness of the seat partition.

[0183] According to a second aspect of the present application, referring to ​ , a vehicle 10 is provided, which comprises the adjusting system 100 described above, and the vehicle 10 has all the beneficial effects of the adjusting system described above, which will not be repeated here.
