Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more specifically to a massage system and a vehicle. Background Technology

[0002] In the field of vehicle technology, seats, as an important component of the vehicle, are crucial to the driving and riding experience. Related technologies often incorporate lumbar support and massage features to enhance seat comfort. These lumbar supports not only provide lumbar support but also massage the lower back of the occupants to alleviate driving or passenger fatigue.

[0003] However, the massage lumbar support in the relevant technology generates significant noise in the passenger compartment during operation, resulting in poor NVH performance of the vehicle. Summary of the Invention

[0004] The purpose of this invention is to provide a massage system and vehicle to overcome the problem in the related art that massage systems generate a lot of noise in the passenger compartment, resulting in poor NVH performance of the vehicle.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] According to a first aspect of this application, this application provides a massage system for a vehicle seat. The massage system includes an air supply device for an air suspension system, a massage module, and a pneumatic control module. The massage module is disposed on the seat and includes at least one massage airbag. The air supply device is connected to at least one massage airbag and is used to supply gas to at least one massage airbag. The pneumatic control module is connected between at least one massage airbag and the air supply device. The pneumatic control module includes a pressure reducing valve for reducing the pressure of the output gas from the air supply device.

[0007] Based on the above-mentioned technical means, by using the air supply device of the air suspension system to supply air to the massage airbags, the need for additional devices such as air pumps specifically for supplying air to the massage airbags can be eliminated, thereby avoiding the noise generated by these devices operating in the passenger compartment and improving the vehicle's NVH performance.

[0008] In addition, the pressure reducing valve can prevent safety hazards such as damage to the massage system or rupture of the airbag caused by excessive gas pressure supplied by the gas supply device, thereby ensuring the safe operation of the entire massage system.

[0009] In some alternative implementations, the output pressure of the pressure reducing valve is greater than or equal to 1.065 bar and less than or equal to 1.1 bar.

[0010] Based on the aforementioned technical methods, if the output air pressure of the pressure-reducing valve is less than 1.065 bar, the pressure-building efficiency of the massage airbag may be low, or the massage pressure may not meet the requirements. If the output air pressure of the pressure-reducing valve is greater than 1.1 bar, the massage force of the massage airbag may be too strong, or the massage airbag and other structures may be damaged. By ensuring that the output air pressure of the pressure-reducing valve is greater than or equal to 1.065 bar and less than or equal to 1.1 bar, within this range, the output air pressure of the pressure-reducing valve can meet the massage pressure requirements of the massage module, ensure that the massage airbag can build up pressure quickly, and avoid damage to the massage airbag due to excessive air pressure.

[0011] In some alternative implementations, the pneumatic control module further includes an adjustment component connected to the pressure-reducing valve and used to adjust the output air pressure of the pressure-reducing valve.

[0012] Based on the aforementioned technical means, by setting an adjustment component, the pressure value of the gas output by the pressure reducing valve can be dynamically adjusted, thereby changing the degree of expansion of the massage airbag and the pressure intensity applied to the user's waist, in order to adapt to the user's diverse needs.

[0013] In some alternative implementations, there are multiple massage modules and multiple seats, each seat having at least one massage module; the pneumatic control module also includes a distribution valve connected between the air supply device and the massage module; the air inlet of the distribution valve is connected to the air outlet of the air supply device, and the distribution valve has multiple air outlets, each corresponding to at least one massage airbag of the multiple massage modules.

[0014] Based on the above technical means, by setting up a distribution valve, the air supply device can provide an independent air supply to multiple seats in the vehicle, thus avoiding the redundant design of configuring an air supply device separately for each seat or each massage module.

[0015] In some alternative implementations, the distribution valve is a multi-way valve.

[0016] Based on the above technical means, by setting the distribution valve as a multi-way valve, it is beneficial to reduce the number of parts and simplify the layout of the massage system.

[0017] In some alternative implementations, the distribution valve includes multiple two-way valves, the inlet ends of which are connected to the outlet end of the pressure reducing valve.

[0018] Based on the above technical means, each two-way valve can independently control the massage airbag of one seat, so that even if one of the two-way valves fails, it will not affect the normal operation of other channels.

[0019] In some alternative implementations, the distribution valve is a solenoid valve.

[0020] Based on the above-mentioned technical means, the solenoid valve can sensitively control the flow of air at each air inlet and outlet, ensuring that the pressure build-up or pressure release action of the massage airbag is sensitive and improving the user experience.

[0021] In some alternative implementations, the pressure reducing valve, distribution valve, and air supply device are all located outside the passenger compartment of the vehicle.

[0022] Based on the above-mentioned technical means, the noise generated during the operation of the massage system can be further reduced to avoid interference with the occupants in the passenger compartment, thereby reducing the noise level in the cabin and further improving the vehicle's NVH performance.

[0023] In some alternative implementations, the pressure relief valve and the distribution valve are located in the vehicle chassis.

[0024] Based on the above-mentioned technical means, the noise generated during the operation of the massage system can be further reduced to avoid interference with the occupants in the passenger compartment, thereby reducing the noise level in the cabin and further improving the vehicle's NVH performance.

[0025] In some alternative embodiments, the pneumatic control module further includes a control valve assembly connected between the pressure reducing valve and at least one massage airbag of the massage module. The number of control valve assemblies is the same as the number of massage modules and they correspond one-to-one. Each massage module includes multiple massage airbags, and the control valve assembly is used to control the connection between the air supply device and any part of the multiple massage airbags.

[0026] Based on the aforementioned technical means, by setting up a control valve assembly, it is possible to precisely build up or release pressure in multiple airbags according to the user's massage needs, thereby enabling a wider range of massage modes.

[0027] According to a second aspect of this application, this application provides a vehicle that includes the aforementioned massage system and air suspension system, wherein the air suspension system includes air springs and an air supply device is connected to the air springs.

[0028] Based on the aforementioned technical means, the air supply device can provide compressed air for the air springs to adjust the vehicle height and shock absorption performance, and can also provide a stable air source for the massage airbags of the massage module, which helps to reduce the number of vehicle parts and improve the integration level of the vehicle.

[0029] In some alternative embodiments, the air supply device includes an air pump and an air tank, the air pump’s inlet end communicating with the external space, the air pump’s outlet end communicating with the air tank, and the air tank communicating with at least one massage lumbar support; an air handling unit is provided on the side of the air pump’s inlet end facing the external space.

[0030] According to the above-mentioned technical means, by setting up an air handling component, the cleanliness of the gas supplied by the air supply device can be improved, which is conducive to extending the service life of the massage system.

[0031] In some alternative implementations, the air handling assembly includes a filter and a dryer, with the dryer located between the filter and the air pump.

[0032] Based on the above technical means, the filter can remove impurities and prevent dust and particles from entering the air pump and causing wear or blockage. The dryer can remove moisture from the gas. The combination of the two can effectively improve the cleanliness of the gas.

[0033] The beneficial effects of this invention are:

[0034] (1) The massage system of this application supplies air to the massage airbag by utilizing the air supply device of the air suspension system. This eliminates the need for additional devices such as air pumps specifically for supplying air to the massage airbag, thereby helping to avoid noise generated by these devices operating in the passenger compartment and improving the vehicle's NVH performance.

[0035] (2) By setting a pressure reducing valve, this application enables the output air pressure of the air supply device to meet the pressure building requirements of the massage airbag and avoids damage to the massage airbag due to excessive output air pressure of the air supply device.

[0036] (3) By setting up a distribution valve, the air supply device works in conjunction with the distribution valve to provide an independent air supply for multiple seats in the vehicle, thus avoiding the redundant design of configuring an air supply device separately for each seat or each massage module.

[0037] It should be noted that the technical effects of the second implementation method can be found in the technical effects of the corresponding implementation method in the first aspect, and will not be repeated here.

[0038] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0048] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0049] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0050] In some embodiments, see Figure 1 This application provides a massage system 100, which can be used in a vehicle seat. The massage system 100 includes an air supply device 1 for an air suspension system, a massage module 2, and a pneumatic control module 3. The massage module 2 is disposed in the seat and includes at least one massage airbag 21. The air supply device 1 is connected to the at least one massage airbag 21 and is used to supply gas to the at least one massage airbag 21. The pneumatic control module 3 is connected between the at least one massage airbag 21 and the air supply device 1. The pneumatic control module 3 includes a pressure reducing valve 31, which is used to reduce the pressure of the output gas from the air supply device 1.

[0051] Optionally, the massage module 2 can be a lumbar support module or a neck support module, that is, the massage module 2 can be set in different positions of the vehicle seat to provide massage for different parts of the driver's and passenger's body.

[0052] The massage module 2, including at least one massage airbag 21, can be configured in several ways: for example, the massage module 2 may include one massage airbag 21; or, for another example, the massage module 2 may include multiple massage airbags 21, arranged in two rows, with each row including multiple massage airbags 21. During the operation of the massage system 100, gas can be delivered into different massage airbags 21 to achieve massage of different parts of the body by the massage module 2.

[0053] It should be noted that the air supply device 1 being connected to at least one massage airbag 21 means that the air supply device 1 and at least one massage airbag 21 are connected by a pipeline to form a gas supply and delivery channel. By using the air supply device 1 of the air suspension system to supply gas to the massage airbags 21, a dedicated device for supplying gas to the massage airbags 21 is no longer needed, reducing the number of parts and saving production costs. Furthermore, these devices no longer need to be placed inside the seat, avoiding the significant noise they would generate within the passenger compartment, thus improving the vehicle's NVH performance.

[0054] During the operation of the massage system 100, the air supply device 1 can inject air into the massage airbag 21, causing the massage airbag 21 to expand and reach the pressure value required for massage. This process is usually called pressure building, which ensures that the massage airbag 21 provides sufficient support and massage intensity, thereby effectively relieving physical fatigue and increasing comfort.

[0055] For example, the massage module 2 is a lumbar support module, and the operation of the massage system 100 may include the following steps: First, when it is necessary to massage the waist, the air supply device 1 is activated; then, the air supply device 1 supplies gas to the massage airbag 21 of the lumbar support module, and the massage airbag 21 completes pressure build-up; finally, the massage airbag 21 massages the waist.

[0056] The connection of the pneumatic control module 3 between at least one massage airbag 21 and the air supply device 1 means that the pneumatic control module 3 and at least one massage airbag 21, as well as the pneumatic control module 3 and the air supply device 1, are connected by pipelines to form a gas supply and delivery channel.

[0057] For example, the massage module 2 is a lumbar support module, and the operation of the massage system 100 may include the following steps: First, when it is necessary to massage the waist, the air supply device 1 is activated; then, the air supply device 1 supplies gas to the pressure reducing valve 31, and the pressure reducing valve 31 reduces the air pressure of the output gas of the air supply device 1 to the air pressure required by the massage airbag 21; then, the pressure reducing valve 31 supplies gas to the massage airbag 21, and the massage airbag 21 is pressurized to realize the massage action.

[0058] Based on this, by utilizing the air supply device 1 of the air suspension system to supply air to the massage airbag 21, the need for additional devices such as a dedicated air pump for supplying air to the massage airbag 21 can be eliminated. This avoids noise generated by these devices operating in the passenger compartment, improving the vehicle's NVH performance. Eliminating the need for additional devices such as a dedicated air pump for supplying air to the massage airbag 21 also helps reduce the cost of the massage system 100. Furthermore, the elimination of the need for frequent air pump operation saves electricity and improves the overall vehicle's power efficiency. The pressure reducing valve 31 prevents damage to the massage system 100 or airbag rupture caused by excessively high gas pressure supplied by the air supply device 1, thus ensuring the safe operation of the entire massage system 100.

[0059] In addition, since the air supply device 1 of the air suspension system usually outputs a high gas pressure value and the air source of the air supply device 1 can be stably and continuously output, supplying gas to the massage airbag 21 through the air supply device 1 can improve the pressure building efficiency of the massage airbag 21 and help the massage airbag 21 achieve rapid pressure building.

[0060] See Figure 1 In some embodiments, the output pressure of the pressure reducing valve 31 is greater than or equal to 1.065 bar and less than or equal to 1.1 bar.

[0061] For example, the output pressure of the pressure reducing valve 31 can be 1.065 bar, 1.08 bar, 1.085 bar, 1.09 bar, 1.1 bar, etc.

[0062] Optionally, the output air pressure range of the air supply device 1 can be greater than or equal to 10 bar and less than or equal to 18 bar. For example, the output air pressure of the air supply device 1 can be 10 bar, 12 bar, 14 bar, 15 bar, 18 bar, etc. The pressure reducing valve 31 is connected between the air supply device 1 and the massage airbag 21, and can effectively reduce the pressure of the output gas of the air supply device 1 to the air pressure required by the massage airbag 21.

[0063] For example, when other parameters of the massage system 100 are constant, such as the length and diameter of the pipeline of the massage system 100, the output air pressure of the pressure reducing valve 31 is within the range of greater than or equal to 1.065 bar and less than or equal to 1.1 bar. This requires that the air supply flow rate of each massage module 2 reach greater than 7 L / min in order to meet the requirements of massage intensity.

[0064] Based on this, if the output air pressure of the pressure reducing valve 31 is less than 1.065 bar, the pressure-building efficiency of the massage airbag 21 may be low, or the massage pressure may not meet the requirements. If the output air pressure of the pressure reducing valve 31 is greater than 1.1 bar, the massage force of the massage airbag 21 may be too strong, or the massage airbag 21 and other structures may be damaged. By ensuring that the output air pressure of the pressure reducing valve 31 is greater than or equal to 1.065 bar and less than or equal to 1.1 bar, within this range, the output air pressure of the pressure reducing valve 31 can meet the massage pressure requirements of the massage module 2, ensure that the massage airbag 21 can build up pressure quickly, and avoid damage to the massage airbag 21 due to excessive air pressure.

[0065] In some embodiments, the pneumatic control module 3 may further include an adjustment component connected to the pressure reducing valve 31 and used to adjust the output air pressure of the pressure reducing valve 31.

[0066] When the output air pressure of the pressure reducing valve 31 changes, the pressure build-up speed of the massage airbag 21 and the pressure value inside the massage airbag 21 within a certain period of time will change, thereby changing the massage effect of the massage module 2.

[0067] Since different drivers and passengers have different preferences for the massage intensity of the massage module 2, the adjustment component can adjust the output air pressure of the pressure reducing valve 31, thereby flexibly adjusting the gas pressure of the input airbag so that users can choose different massage intensities (such as gentle, standard, and strong) according to their own preferences or physical conditions to meet the diverse massage needs of users.

[0068] For example, the regulating component may be electrically connected to the pressure reducing valve 31, or the regulating component may be mechanically connected to the pressure reducing valve 31.

[0069] Optionally, the adjustment assembly may include a manual adjustment element, such as a manual knob-type adjustment valve; the adjustment assembly may be located in the engine compartment or trunk of the vehicle, allowing the user to manually adjust it to change the output air pressure of the pressure reducing valve 31.

[0070] Optionally, the regulating component may include an automatic regulating element, such as an electric proportional valve or a servo motor driven valve, which allows the user to remotely adjust the output air pressure of the pressure reducing valve 31 via buttons or touch keys.

[0071] Optionally, the vehicle's control system can also automatically switch pressure settings through adjustment components to provide adaptive support and massage based on driving modes (such as long-distance driving, aggressive driving).

[0072] Based on this, the pressure value of the gas output by the pressure reducing valve 31 can be dynamically adjusted by setting the adjustment component, thereby changing the degree of expansion of the massage airbag 21 and the pressure intensity applied to the user's waist to adapt to the user's diverse needs.

[0073] In some optional embodiments, the pneumatic control module 3 includes a connected pressure-reducing valve 31 and an adjustment component. The output air pressure of the pressure-reducing valve 31 is greater than or equal to 1.065 bar and less than or equal to 1.1 bar. The adjustment component can effectively adjust the output air pressure of the pressure-reducing valve within its range to realize multiple massage modes of the massage system 100.

[0074] See Figure 1 In some embodiments, there are multiple massage modules 2 and multiple seats, with each seat having at least one massage module 2. The pneumatic control module 3 also includes a distribution valve 32, which is connected between the air supply device 1 and the massage modules 2. The air inlet of the distribution valve 32 is connected to the air outlet of the air supply device 1, and the distribution valve 32 has multiple air outlets, each correspondingly connected to at least one massage airbag 21 of the multiple massage modules 2.

[0075] The distribution valve 32 can control the on / off connection between its multiple air outlets and the massage airbags 21 of the multiple massage modules 2. The distribution valve 32 enables independent control of the massage modules 2 of different seats.

[0076] If all air outlets are open, the air supply device 1 can supply air to multiple massage modules 2 simultaneously; if some air outlets are closed, the air supply device 1 will stop supplying air to the massage module 2 corresponding to that air outlet. Each seat can be equipped with one or more massage modules 2.

[0077] For example, when a seat is equipped with multiple massage modules 2, the multiple massage modules 2 can be arranged in left and right partitions, or they can be arranged in upper and lower partitions.

[0078] By setting the distribution valve 32, the gas pressure delivered to the massage airbags 21 of different seats can also be adjusted. For example, different massage intensities can be set for the front driver's seat and the rear passenger seat.

[0079] The timing of inflation and deflation is controlled by the distribution valve 32, enabling the massage module 2 to achieve massage modes with different rhythms and frequencies. For example, the distribution valve 32 can be used for high-frequency opening and closing control, such as opening the valve once every 0.5 seconds and pausing for 0.5 seconds, completing one cycle in 1 second, thereby allowing the massage airbag 21 to provide a continuous massage and tapping sensation.

[0080] Based on this, by setting up a distribution valve 32, the air supply device 1, in conjunction with the distribution valve 32, can provide an independent air supply to multiple seats in the vehicle, avoiding the redundant design of configuring an air supply device separately for each seat or each massage module 2.

[0081] See Figure 1 In some embodiments, the distribution valve 32 is a multi-way valve. The multi-way valve has an inlet port 321 and multiple outlet ports 322. The inlet port 321 is connected to the air supply device 1, and the multiple outlet ports 322 are respectively connected to the massage airbags 21 of different seats. In this way, gas from the air supply device 1 of the air suspension system can be distributed to the massage airbags 21 of multiple seats through a single multi-way valve, avoiding the complex wiring and redundant components required for each airbag to be individually connected to the air supply system.

[0082] For example, when the massage system 100 is used in a five-seater vehicle, the multi-way valve has four air outlet ports 322. These four ports 322 can be connected to the front and rear seats of the vehicle via four separate pipes. The lengths of these four pipes can be 2.5m, 2m, and 2m respectively, corresponding to the massage modules 2 of the left front, right front, left rear, and right rear seats of the vehicle. The pipes can be made with an outer diameter of 6mm and a wall thickness of 1.5mm.

[0083] Based on this, by setting the distribution valve 32 as a multi-way valve, it is beneficial to reduce the number of parts and simplify the layout of the massage system 100.

[0084] In some embodiments, the distribution valve 32 includes multiple two-way valves, the air inlets of which are connected to the air outlet of the pressure reducing valve 31. By controlling the opening and closing of different two-way valves, independent control of the massage airbags 21 of different seats can be achieved.

[0085] Based on this, each two-way valve can independently control the massage airbag 21 of one seat, so that even if one of the two-way valves fails, it will not affect the normal operation of other channels.

[0086] See Figure 1 In some embodiments, the distribution valve 32 is a solenoid valve. Based on this, the solenoid valve can quickly and sensitively control the flow of air at each air inlet and outlet, ensuring that the massage airbag 21 can build up or release pressure responsively, thus improving the user experience. The solenoid valve also facilitates more precise pressure control.

[0087] In some alternative embodiments, the distribution valve 32 integrates a connector that connects to the vehicle's control system via a wiring harness to control the on / off state of each outlet of the distribution valve 32.

[0088] In some embodiments, the pressure-reducing valve 31, the distribution valve 32, and the air supply device 1 are all located outside the passenger compartment of the vehicle. Optionally, the air supply device 1 is typically located on the longitudinal beam of the vehicle, and the pressure-reducing valve 31 and the distribution valve 32 can be located close to the air supply device 1 to simplify the piping layout. For example, the air supply device 1 is located on the front longitudinal beam of the vehicle, and the pressure-reducing valve 31 and the distribution valve 32 can be located in the engine compartment of the vehicle.

[0089] Based on this, the noise generated during the operation of the massage system 100 can be further reduced to avoid interference with the occupants in the passenger compartment, thereby lowering the noise level in the cabin and further improving the vehicle's NVH performance.

[0090] In some embodiments, the pressure relief valve 31 and the distribution valve 32 are located in the vehicle chassis. This further reduces the noise generated during the operation of the massage system 100 from interfering with the occupants in the passenger compartment, lowers the noise level in the cabin, and further improves the vehicle's NVH performance.

[0091] See Figure 1 In some embodiments, the pneumatic control module 3 further includes a control valve assembly 33, which is connected between the pressure reducing valve 31 and at least one massage airbag 21 of the massage module 2. The number of control valve assemblies 33 is the same as the number of massage modules 2, and they correspond one-to-one. Each massage module 2 includes multiple massage airbags 21, and the control valve assembly 33 is used to control the connection between the air supply device 1 and any part of the multiple massage airbags 21.

[0092] The number of control valve assemblies 33 is the same as the number of massage modules 2, and the two are connected in a one-to-one correspondence, so that the control valve assembly 33 can realize independent control of the massage airbag 21 of each massage module 2.

[0093] The control valve assembly 33 controls the connection between the air supply device 1 and any part of the multiple massage airbags 21, enabling the massage airbags 21 to achieve various massage modes, such as kneading, pushing, and wave massage.

[0094] Optionally, the control valve assembly 33 can also control the massage airbags 21 in different zones on the left and right or up and down of a single seat, which helps to improve the massage effect.

[0095] For example, the control valve assembly 33 can be directly connected between the pressure reducing valve 31 and the massage airbag 21 of the massage module 2. In this way, the connection between the corresponding massage airbag and the air supply device can be controlled by the corresponding control valve assembly 33 of each seat to achieve their respective massage needs. That is to say, the control valve assembly 33 and the pressure reducing valve 31 can be connected by a multi-port pipe, eliminating the need for a separate distribution valve 32.

[0096] For example, the control valve assembly 33 can be connected between the distribution valve 32 and the massage airbag 21 of the massage module 2. That is, the control valve assembly 33 is indirectly connected between the distribution valve 32 and the massage airbag 21 of the massage module 2. In this way, through the cooperation of the distribution valve 32 and the control valve assembly 33, effective control of the massage airbag 21 of each seat's massage module 2 can be achieved. The distribution valve 32 is mainly used to control the air supply to the massage airbag, while the control valve assembly 33 is mainly used to realize different massage modes.

[0097] Based on this, by setting the control valve assembly 33, it is possible to precisely build up or release pressure on multiple airbags according to the user's massage needs, so as to achieve a wider range of massage modes.

[0098] In some optional embodiments, when the output air pressure of the air supply device 1 and the pressure reducing valve 31 is constant, the massage intensity can be controlled by adjusting the opening and closing time of the distribution valve 32. This means adjusting the massage intensity of the massage airbag 21 by controlling its inflation time. For example, when the inflation time is 1 second, the maximum massage intensity of the massage airbag 21 can exceed 20N; when the inflation time is 2 seconds, the maximum massage intensity can exceed 30N; and when the inflation time is 3 seconds, the maximum massage intensity can exceed 40N.

[0099] For example, when the massage system 100 needs to massage the driver or passenger, the massage system 100 includes the following operating steps:

[0100] First, passengers can select the massage mode through the user interface (such as the central control screen, seat buttons, or voice assistant);

[0101] Next, the air supply device 1 starts supplying air, and the gas in the air supply device 1 is delivered to the pressure reducing valve 31. The pressure reducing valve 31 reduces the high pressure gas to the air pressure range required by the massage airbag 21.

[0102] Next, the depressurized gas enters the distribution valve 32, which distributes the gas to the massage modules 2 of the seats that require massage.

[0103] Next, the distributed gas enters the corresponding seat control valve assembly 33. The control valve assembly 33 operates according to the massage mode selected by the driver or passenger. Each control valve assembly 33 controls the connecting pipe of multiple massage airbags 21 in the corresponding massage module 2, and causes the massage airbags 21 to build up pressure. The massage airbags 21 inflate and apply pressure to the user's body parts.

[0104] In some embodiments, this application provides a vehicle, wherein the specific type of vehicle is not specifically limited in the embodiments of this application. For example, the vehicle provided in the embodiments of this application can be an electric vehicle, a hybrid electric vehicle, or a solar-powered vehicle, etc. Furthermore, the vehicle provided in the embodiments of this application can also be of different forms. For example, the vehicle provided in the embodiments of this application can be a sedan, a sport utility vehicle (SUV), or a multi-purpose vehicle (MPV).

[0105] The vehicle may include the massage system 100 and the air suspension system described above. The air suspension system includes air springs, and the air supply device 1 is connected to the air springs.

[0106] Based on this, the air supply device 1 can provide compressed air for the air spring to adjust the vehicle height and shock absorption performance, and can also provide a stable air source for the massage airbag 21 of the massage module 2. This helps to reduce the number of vehicle parts and improve the integration level of the vehicle.

[0107] See Figure 2 In some embodiments, the air supply device 1 includes an air pump and an air tank. The air pump's inlet is connected to an external space, and the air pump's outlet is connected to the air tank. The air tank is connected to at least one massage lumbar support. An air handling assembly 5 is provided on the side of the air pump facing the external space.

[0108] For example, the air treatment component 5 can remove impurities from the air, which can reduce the wear of these impurities on the internal parts of the air pump (such as pistons, blades, etc.) and subsequent pipelines, pressure reducing valve 31, distribution valve 32 and other components, thereby benefiting the service life of the air supply device 1 and the massage system 100.

[0109] For example, the air handling unit 5 can also reduce the humidity of the air entering the air pump, which helps prevent metal parts from rusting or corroding due to moisture, and further protects the air supply unit 1 and the massage system 100 from damage.

[0110] Based on this, by setting up the air handling component 5, the cleanliness of the gas supplied by the air supply device 1 can be improved, which helps to extend the service life of the massage system 100.

[0111] In addition, clean and stable air intake helps maintain a constant pressure inside the air tank, which in turn helps ensure the normal operation of the massage lumbar support system.

[0112] In some embodiments, the air handling assembly 5 includes a filter 51 and a dryer 52, with the dryer 52 located between the filter 51 and the air pump.

[0113] Based on this, the filter element 51 can remove impurities and prevent dust and particles from entering the air pump and causing wear or blockage. The dryer 52 can remove moisture from the gas. The combination of the two can effectively improve the cleanliness of the gas supplied by the gas supply device 1.

[0114] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
