In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] The following describes a seat adjustment method according to an embodiment of the present invention with reference to the accompanying drawings.

[0028] The user side of the seat according to the embodiment of the present invention is provided with a plurality of airbags. It is understandable that the airbag is provided on the upper side of the seat cushion, when the seat has a backrest, the front side of the backrest is provided with an airbag, and when the seat has side wings, the two side wings have airbags on the sides facing each other. The airbags can provide support for the user after being inflated. In addition, an air pump is also provided in the seat, and the air pump is connected to the airbag through an air pipe, which is used to inflate and deflate the airbag and adjust the inflation amount of the airbag.

[0029] In some embodiments of the present invention, the seat includes a seat cushion, a backrest and side wings, and the seat cushion, backrest and side wings are all provided with multiple airbags. For example, the seat backrest, seat cushion and side wings have a total of 39 supporting airbags, and the backrest is arranged with 18 airbags, each side of the side wing is arranged with 6 airbags, a total of 12 airbags on both sides, and the seat cushion is arranged with 9 airbags.

[0030] Optionally, the airbag is made of plastic with excellent airtightness, which can maintain the stability of the air pressure inside the airbag and provide support and massage effects.

[0031] Optionally, the air pump is made of plastic and metal and is used for inflating and deflating the airbag.

[0032] The seat adjustment method according to an embodiment of the present invention includes:

[0033] Obtain the pressure applied to multiple airbags after the user sits down, wherein each airbag is attached with a pressure sensor, and the pressure sensor on each airbag monitors the user's sitting pressure distribution in real time, and the pressure sensor can detect the small pressure changes and change trends applied by the user on the airbag, and the pressure applied to multiple airbags is obtained by obtaining the pressure of each pressure sensor;

[0034] The inflation amount of the multiple airbags is adjusted according to the pressure change applied to the multiple airbags. The seat has a central processing unit, and the central processing unit is connected to the pressure sensor through a data line or wireless communication. The central processing unit is also connected to the air pump through a data line or wireless communication. The pressure data detected by the pressure sensor can be sent to the central processing unit, and the central processing unit can receive the data of the pressure sensor, calculate and output the adjustment instructions of the airbag according to the data of the pressure sensor, and adjust the inflation amount of the multiple airbags through the air pump.

[0035] Specifically, when the pressure detected by the airbag increases, the airbag is controlled to be deflated, thereby reducing the support provided by the airbag to the user and reducing the pressure applied by the user to the airbag; when the pressure detected by the airbag decreases, the airbag is controlled to be inflated, thereby increasing the support provided by the airbag to the user. For example, when the user leans to the left, the pressure detected by the pressure sensor on the airbag on the left wing will increase, while the pressure detected by the pressure sensor on the airbag on the right side wall will decrease. At this time, the airbag on the left wing is controlled to be deflated, thereby reducing the support provided to the user and avoiding squeezing the user, thereby enabling the user to lean to the left better, and the airbag on the right wing is controlled to be inflated, thereby increasing the support provided to the user and improving the sense of wrapping for the user.

[0036] Optionally, the airbag and the pressure sensor are connected by 3M glue. The pressure sensor is the same size as the airbag and is attached to the surface of the airbag. For example, the pressure sensor can be attached only to the side of the airbag facing the user, that is, the side away from the seat frame. Of course, the pressure sensor can also be attached to all surfaces of the airbag.

[0037] Optionally, the central processing unit is an integrated circuit, using standard semiconductor materials and having a compact size.

[0038] Optionally, the seat may also include a data preprocessing module, which is used to filter and calibrate the collected data to eliminate noise and outliers and improve data quality, so that the central processing unit can accurately judge the change in pressure and issue accurate control instructions.

[0039] According to the seat adjustment method of the embodiment of the present invention, by adjusting the inflation amount of the airbags according to the change of the pressure applied to the multiple airbags, the support effect of the seat airbags can be automatically adjusted according to the user's weight, sitting posture, etc., so as to provide the most comfortable and healthy sitting experience. And it can be adjusted according to the user's real-time physiological state and sitting posture changes, with intelligent and personalized adjustment functions, improving the user's comfort and avoiding user discomfort caused by long-term use.

[0040] In some embodiments of the present invention, before the user sits down, the seat adjustment method further includes:

[0041] Control multiple airbags to inflate and deflate to a preset comfort state. The preset comfort state is a relatively comfortable state for the user, which allows the user to feel comfortable the first time sitting on the seat. In the preset comfort state, due to different weights or postures of the user, slight adjustments can be made for easy adjustment.

[0042] Among them, the seat has a user interaction interface and a storage unit, and the user interaction interface and the storage unit are connected to the central processing unit through a data cable or wireless communication. The user interaction interface can be set on the seat or on a terminal device such as a mobile phone. The storage unit can store the parameters of the airbag inflation amount and / or the pressure parameters applied to the airbag in a preset comfort state. The user interaction interface allows the user to set preferred parameters and view the seat status. The user can adjust the seat to a preset comfort state through the user interaction interface before or after sitting down.

[0043] In some embodiments of the present invention, the preset comfort state is the state of the seat adjustment when the user uses it for the first time or the state recorded after the last use when the user uses it for the Nth time, where N is greater than or equal to 3.

[0044] When the user uses the seat for the first time after obtaining it, after sitting in the seat, the user sets the inflation volume of multiple airbags according to his / her preferences through the user interaction interface until he / she feels comfortable, records the value of the pressure sensor and the inflation volume of the airbag at this time, and stores them as a user profile as a preset comfort state for subsequent use. Among them, the inflation volume in the preset comfort state is the preset inflation volume.

[0045] In addition, when used by multiple users, multiple preset comfort states suitable for different users can be recorded and stored. When different users use the seat, the user can call up the preset comfort state suitable for themselves through the user interaction interface, and the support strength of the airbag can be adjusted for each user according to the usage habits of different users.

[0046] Specifically, when the user uses the seat for the second time, the user can call up the parameters of the preset comfort state set during the first use through the user interaction interface. Of course, the user's sitting posture may be different during each use. During use, the airbag on the seat adjusts the inflation amount according to the user's state. After the adjustment, the inflation amount of the airbag and the pressure value applied to the airbag can be recorded and stored as the parameters of the preset comfort state for the next use.

[0047] In some embodiments of the present invention, the pressure applied by the user on the airbag in the preset comfort state is the preset pressure, and adjusting the inflation amount of the multiple airbags according to the pressure change applied on the multiple airbags includes:

[0048] The inflation amounts of the multiple airbags are adjusted according to the change of the current pressure applied by the user on the airbags relative to the preset pressure.

[0049] Among them, the preset comfort state is the state that the user previously considered comfortable. When the pressure applied by the user on the multiple airbags changes relative to the pressure applied on the airbags in the preset comfort state, it means that the user's posture has changed. It is necessary to adjust the inflation amount of the multiple airbags according to the user's new posture, thereby adjusting the supporting strength of the airbags and improving the user's comfort.

[0050] Furthermore, the seat adjustment method further includes:

[0051] Determining that a current pressure change applied to the airbag is greater than or equal to a first preset value and lasts for a first preset time;

[0052] Control the inflation and deflation of the airbag when the current pressure change is greater than or equal to the first preset value.

[0053] When the current pressure applied to the airbag changes relative to the preset pressure by a value greater than or equal to a first preset value and lasts for a first preset time, it can be determined that the user's posture has changed, thereby avoiding misjudgment.

[0054] Specifically, controlling the inflation and deflation of the airbag so that the current pressure change is greater than or equal to the first preset value includes:

[0055] When the current pressure is greater than the preset pressure, the airbag is controlled to deflate;

[0056] When the current pressure is lower than the preset pressure, the airbag is controlled to inflate.

[0057] It can be understood that when the current pressure applied to the airbag becomes greater than or equal to the first preset value and lasts for the first preset time, the airbag is controlled to deflate to avoid excessive airbag gas pressing against the user, thereby ensuring the user's comfort; when the current pressure applied to the airbag becomes greater than or equal to the first preset value and lasts for the first preset time, the airbag is controlled to inflate to avoid too little airbag gas to provide support to the user, thereby ensuring the user's comfort.

[0058] Furthermore, the airbag whose current pressure change is greater than or equal to the first preset value is controlled to be inflated and deflated until the airbag is pressurized to the preset pressure value, thereby enabling the airbag to support the user to achieve a comfortable feeling in a preset comfortable state, thereby ensuring the user's comfort.

[0059] Optionally, the first preset value is 5%-15%, for example, 10%; the first preset time is 5s-15s, for example, 10s. This can avoid misjudgment and adjust the inflation volume of the airbag in time to improve the user's comfort.

[0060] In some embodiments of the present invention, the backrest of the seat has an airbag, and the angle of the backrest of the seat relative to the seat cushion of the seat is adjustable, and the seat adjustment method further includes:

[0061] It is determined that the current pressure applied to the airbag on the seat back increases and the change is greater than or equal to a second preset value and lasts for a second preset time. This indicates that the user is leaning back on the seat back and wants to be in a reclining position.

[0062] The backrest is controlled to adjust to the reclining mode, and the upper end of the backrest rotates backward relative to the seat cushion. When the backrest rotates backward, the user can be in a semi-reclining or fully lying state, which improves the adaptability of the seat and the comfort of the user and enhances the intelligence and automation level of the seat.

[0063] In this way, the state of the seat can be adjusted according to the user's tendency to recline, and the seat can be automatically placed in the reclining mode.

[0064] Furthermore, the seat adjustment method further includes:

[0065] Adjust the inflation amount of the airbag on the backrest. This can make the inflation amount of the airbag on the backrest better adapt to the user's body posture. Among them, the inflation amount of the airbag on the backrest can be adjusted until the pressure applied to the airbag is a preset pressure.

[0066] For example, the airbag on the backrest opposite to the user's waist is inflated to increase the support for the user's waist and protect the user's waist; the airbag on the backrest opposite to the user's neck is inflated to increase the support for the user's neck and protect the user's neck; the airbag on the backrest opposite to the user's back is deflated to reduce the support for the user's back, allowing the user to lie better on the backrest.

[0067] Optionally, the second preset value is 5%-15%, such as 10%, and the second preset time is 5s-15s, such as 10s, thereby avoiding misjudgment and timely adjusting the seat state and the inflation volume of the airbag to improve the user's comfort.

[0068] In some embodiments of the present invention, the seat adjustment method further includes:

[0069] determining that the pressure applied to the plurality of airbags does not change or continues to change for a third preset time;

[0070] The seat is controlled to enter a soothing mode, and at least part of the airbags are controlled to alternately inflate and deflate for massage.

[0071] When the pressure applied to multiple airbags remains unchanged for the third preset time or changes for the third preset time, it means that the user has been in one posture for a long time, sitting or lying for a long time. At this time, the seat is controlled to enter the soothing mode, and at least some of the airbags are controlled to inflate and deflate alternately. The same airbag can massage the user during the inflation and deflation process, thereby improving the user's comfort.

[0072] Optionally, the third preset time is 30 min-60 min, for example 45 min.

[0073] In some embodiments of the present invention, the seat adjustment method further includes:

[0074] The adjusted inflation volume is stored and used as the inflation volume for the updated preset comfort state.

[0075] It is understandable that when the user uses the seat, the seat will be adjusted according to the user's posture, etc., and the inflation amount after each adjustment will be stored and used as the inflation amount for the updated preset comfort state. Correspondingly, the pressure applied by the user on the airbag after adjustment will be used as the preset pressure in the preset comfort state. The user's comfort can be better met when the user uses the seat next time.

[0076] In some embodiments of the present invention, the seat adjustment method further includes:

[0077] Determine that the user leaves the seat;

[0078] Optimize the current airbag inflation volume and the preset comfort state airbag inflation volume;

[0079] The optimized inflation volume of the airbag is used as the inflation volume of the updated preset comfort state.

[0080] For example, when the current inflation volume of the airbag is different from the inflation volume of the airbag in the preset comfort state, a suitable inflation volume value between the current inflation volume and the inflation volume of the airbag in the preset comfort state is taken as the optimized inflation volume of the airbag, and also as the inflation volume of the updated preset comfort state. In this way, the user's comfort can be satisfied when using the seat next time.

[0081] Among them, the collected data, such as the current inflation volume of the airbag, can be uploaded to the cloud platform through the data upload module, and the inflation volume of the airbag under the preset comfort state can be uploaded to the cloud platform. The cloud platform processing unit processes the data on the cloud platform and optimizes the inflation volume and pressure value of the airbag. The cloud data sending module returns the optimized inflation volume of the airbag to the seat, and uses it as the maximum value of the updated preset comfort state, and makes inflation and deflation adjustment instructions.

[0082] The seat adjustment method according to the embodiment of the present invention adopts advanced artificial intelligence technology, especially fuzzy logic and adaptive control strategy, to achieve precise adjustment of the seat support airbag. The method can automatically adjust the inflation volume of the airbag according to the user's pressure changes and sitting posture trends to provide optimal support and comfort. In addition, the seat can self-learn the user's usage habits and the frequency of use in different scenarios to ensure that the user will have a more comfortable sitting experience every time he sits down, and when the user has a tendency to move, it automatically determines the user's desired usage scenario and automatically adjusts it to the desired location.

[0083] Optionally, the seat of the present application may be a single ordinary seat, or may be a vehicle seat, an aviation seat, etc.
