Description

TECHNICAL FIELD

[0002] With the rapid development of the automobile industry, users have higher and higher demands for the comfort, intelligence, scene and personalization of automobiles. As an important part of the comfort of automobiles, the comfort of seats also needs to be continuously improved.

[0003] At present, in order to improve the comfort of users, some seats are provided with a zero-gravity mode. The zero-gravity refers to that the seat backrest is tilted back to 120°-130°, and the leg rest is lifted at the same time, so that the knees are slightly higher than the heart, forming a "neutral posture" similar to astronauts in a zero-gravity environment, and the seat profile can be adapted to the human body through ergonomic design, so that the body weight is evenly distributed to the back, hips and legs, reducing the pressure on the spine and joints.

[0004] The existing seat profile is designed and checked according to a standard human model, but the human characteristics (such as height and weight) of different users may be quite different, and the existing seat profile is difficult to adapt to some user groups with large differences from the standard human model. In order to adapt to the human characteristics of different users, the posture of the seat often needs to be adjusted, and the relatively comfortable seat posture corresponding to different users is different. When the seat posture changes, the pressure distribution of the human body on the seat will also change, and a single seat profile is difficult to evenly distribute the body weight to the human body, and it is difficult to ensure the comfort of the human body.

[0053] In the present embodiment, as shown in Figure 2 and Figure 3 The seat posture adjustment unit 11 in the seat 1 can comprise a seat framework 111, a headrest adjustment mechanism 112 and a leg support adjustment mechanism 113, and the cooperation mode of each component is a conventional technical means in the art, which will not be described in detail here. Based on the detection result of the feature detection unit, the optimal seat posture of the user is accurately calculated by using big data algorithm, and each component of the above-mentioned seat posture adjustment unit 11 is adjusted to the corresponding seat posture, for example, the seat posture is adjusted according to the height and weight of the user, so that the seat posture is adapted to the body shape of the user; or the seat posture is adjusted according to the fatigue of the user, so that the fatigue of the user can be relieved as needed; or the seat posture is adjusted according to the height and weight of the user, so that the seat posture is adapted to the body shape of the user, and then the seat posture is slightly adjusted according to the fatigue of the user, so that the fatigue of the user can be relieved as needed.

[0054] In the embodiment, the plurality of pressure sensors 141 in the pressure detection unit can be matrix fiber sensors, and all the matrix fiber sensors of the pressure detection unit are distributed on the seat surface to obtain the body pressure distribution of the seat surface.

[0055] In the embodiment, the seat pneumatic adjustment unit 12 in the application includes a plurality of first seat inflation mechanisms distributed between the seat surface 125 and the seat framework 111, each of which includes a first surface air bag 121, a first foam 123 and a deep air bag 122. As shown in the figure, the seat framework 111, the deep air bag 122, the first foam 123, the first surface air bag 121, the pressure sensor 141 and the seat surface 125 are arranged in the order from inside to outside along the seat, and the first surface air bag 121 and the deep air bag 122 are respectively connected with a gas pump, which can be independently inflated based on the inflation needs of the seat. Among them, the size of the air bag is larger than that of the air bag, and the cross-sectional shape of the air bag can be rectangular or elliptical. Figure 5

[0056] In the embodiment, the seat pneumatic adjustment unit 12 is used to adjust the inflation state of the first surface air bag 121 and the deep air bag 122 of each first seat inflation mechanism according to the collected body pressure distribution, wherein the size of the deep air bag 122 is much larger than that of the first surface air bag 121, and when the deep air bag 122 is inflated, the seat surface can have a large change, so that by adjusting the inflation state of the deep air bag 122, the seat surface can be greatly adjusted, so that the seat surface is adjusted to a state close to the user's body shape; the size of the surface air bag is small, and it is distributed under the seat surface, based on the collected body pressure distribution, the pressure distribution of the seat surface when the user sits on the seat can be judged, and each surface air bag can be fine-tuned based on the pressure distribution to make the pressure distribution of the seat surface when the user sits on the seat uniform, providing comfortable support and wrapping for the user, and improving the comfort of the user on the seat.

[0057] In summary, the application can adjust the seat to a comfortable seat posture based on the user's own state through the cooperation of the feature detection unit and the seat posture adjustment unit 11, and can make the seat after the seat posture adjustment have a surface suitable for the user through the cooperation of the pressure detection unit and the seat pneumatic adjustment unit 12, thereby improving the comfort of the user.

[0058] The whole system can be self-adaptive according to the state of different users, improve the number of users adapted, and the whole system is automatically adjusted, avoiding the safety hidden trouble caused by manual adjustment of the user; the posture and surface adjustment of the whole system will make the seat more comfortable, and the support and wrapping will be stronger.

[0059] ​Optionally, the first seat inflation mechanism including the first surface air bag 121 and the deep air bag 122 can be arranged under the seat profile, and the second seat inflation mechanism with the surface air bag but without the deep air bag 122 can be arranged under the partial profile area of the seat.

[0060] In combination with the above embodiments, in some embodiments, the seat pneumatic adjustment unit 12 further includes a second seat inflation mechanism distributed between the seat cover 125 and the seat framework 111, the second seat inflation mechanism including a second surface air bag and a second foam; the seat framework 111, the second foam, the second surface air bag, the pressure sensor 141 and the seat cover 125 are sequentially arranged along the inside to outside direction of the seat, and the second surface air bag is connected with the air pump.

[0061] In the present embodiment, the present application finds that only arranging a layer of inflation member under the seat profile, if the inflation member has a large specification, the volume change of the inflation member after inflation is large, when the inflation member is inflated and contacts the human body, the pressure received by the human body is relatively concentrated, the human body has a strong foreign body sensation, especially in the area where the human body is subjected to a relatively large force, affecting the comfort of the user when sitting; if the specification of the inflation member is small, the volume change of the inflation member after inflation is small, and the human body characteristics (such as height and weight) of different users can be large, when the users with different human body characteristics sit on the seat, the seat profile can be difficult to adapt, and the inflation member with small volume change cannot guarantee to contact the human body or provide sufficient pressure.

[0062] Therefore, the present application provides another embodiment, a double-layer inflation member (one layer on the outside of the seat is a deep air bag, and the other layer on the inside of the seat is a deep air bag) is arranged in the area of the seat profile that is difficult to adapt to users with different human body characteristics, so that the specification of the deep air bag is large, and the specification of the surface air bag is small, the seat profile can be adjusted by a large amplitude through the inflation of the deep air bag 122, and then a small amplitude adjustment is performed through the surface air bag to adapt to different human body characteristics. Some areas of the seat do not need to adjust the profile too much, such as the headrest part of the seat (the size of the head of users with different body types will not have too much difference, so the headrest part of the seat does not need to adjust the profile too much), and only the surface air bag can make the profile of the corresponding area of the seat adapt to different users.

[0063] In combination with the above embodiments, in some embodiments, as shown in Figure 4 The first seat inflation mechanism is arranged in the backrest, the backrest wing, the seat cushion, the seat cushion wing and the leg support of the seat respectively, and the second seat inflation mechanism is arranged in the headrest part of the seat, thereby saving cost.

[0064] In combination with the above embodiments, in some embodiments, the diameters of the first surface air bags 121 and the second surface air bags are both 10-20 mm, and all the surface air bags are arranged relatively closely under the seat profile.

[0065] In combination with the above embodiments, in some embodiments, the arrangement of the deep air bags 122 in the seat is specifically arranged as follows:

[0066] In the seat back, the number of deep air bags 122 is at least 3 (4 are shown in the figure, of which the two above simultaneously support the upper back of the human body), and the three deep air bags 122 are arranged in the seat back corresponding to the upper back, waist, and lumbosacral regions of the human body, respectively, to adapt the profile in the seat back to the curve of the human spine through the support of the three deep air bags 122.

[0067] In the seat cushion, the number of deep air bags 122 is at least 3, and the three deep air bags 122 are arranged in the seat cushion corresponding to the hip and two thighs of the human body, respectively, to fill the gap between the user's thighs and the profile in the seat cushion through the support of the two deep air bags 122 corresponding to the thighs, so that the profile in the seat cushion can effectively support the user's thighs.

[0068] In the seat back side wing, seat cushion side wing, and leg rest, the number of deep air bags 122 is at least 1, for making the corresponding seat profile close to the user's body surface.

[0069] In combination with the above embodiments, in some embodiments, each first seat inflation mechanism includes a plurality of first surface air bags 121, and the plurality of first surface air bags 121 are distributed and abut the outer side surface of the first foam 123.

[0070] In this embodiment, multiple surface air bags can be arranged on the outer side of each deep air bag 122. On this basis, each first seat inflation mechanism can only be provided with one deep air bag 122, and the position of all surface air bags on the outer side of the single deep air bag 122 is adjusted through the inflation of the deep air bag 122, so that the surface air bags can pressurize the surface of the human body of different body types.

[0071] In combination with the above embodiments, in some embodiments, in the seat back, the density of the first surface air bags 121 in the lumbar region of the seat back is greater than the density of the first surface air bags 121 in other regions of the seat.

[0072] In this embodiment, the present application adopts a zoning design for the arrangement of all surface airbags in the seat pneumatic adjustment unit 12 based on the different needs for support strength of different regions of the human body when sitting. Specifically, the present application finds that the lumbar spine of the user needs greater support strength when sitting, and therefore makes the density of the first surface airbag 121 in the lumbar region of the backrest greater than the density of the first surface airbag 121 in other regions of the seat to improve the support strength for the lumbar spine of the user. Further, the density of the first surface airbag 121 in the lumbar region can be increased by 20% compared to other regions.

[0073] Optionally, in some embodiments, the first seat inflation mechanism further comprises a hard fiber felt 124 arranged between the seat framework 111 and the deep airbag 122.

[0074] In combination with the above embodiments, in some embodiments, the seat pneumatic adjustment unit 12 comprises:

[0075] A first determining subunit is configured to determine the relationship between the pressure of the support region corresponding to the deep airbag 122 and a first threshold value based on the collected human body pressure distribution.

[0076] In this embodiment, the first determining subunit can be a microcontroller. The first threshold value can be preset or dynamically adjusted based on the user-selected seat hardness level. When the pressure of the support region corresponding to the deep airbag 122 is less than the first threshold value, it is determined that the seat surface corresponding region is not in contact with the human body or not closely fitted to the human body, and therefore the deep airbag 122 needs to be inflated to adjust the seat surface to fit the human body surface.

[0077] A first control subunit is configured to inflate the deep airbag 122 by a gas pump connected to the deep airbag 122 when the pressure of the support region corresponding to the deep airbag 122 is less than the first threshold value.

[0078] In this embodiment, the first control subunit can be a gas pump connected to the deep airbag 122. When the gas pump receives a signal from the first determining subunit indicating that the pressure of the support region corresponding to the deep airbag 122 is less than the first threshold value, the gas pump inflates the deep airbag 122 until it receives a signal from the first determining subunit indicating that the pressure of the support region corresponding to the deep airbag 122 is equal to or greater than the first threshold value.

[0079] The pressure detection unit is configured to collect the human body pressure distribution of the user on the seat after all deep airbags 122 are inflated and adjusted by a plurality of pressure sensors 141.

[0080] In the embodiment, the pressure detecting unit is further configured to re-collect the body pressure distribution of the user on the seat by the plurality of pressure sensors 141 after the deep air bags 122 are fully inflated and adjusted, and the collected body pressure distribution is used to further inflate and adjust the surface air bags.

[0081] The second determining sub-unit is configured to determine the relationship between the pressure detected by the pressure sensor 141 near the surface air bag and the second threshold value based on the re-collected body pressure distribution, and the surface air bag includes the first surface air bag 121 and the second surface air bag.

[0082] In the embodiment, the second determining sub-unit can be a microcontroller. The second threshold value can be a pressure value when the seat profile pressure distribution is uniform, which is derived based on the body pressure distribution detected by the pressure detecting unit, or a value dynamically adjusted based on the seat hardness level selected by the user. When the pressure collected by the pressure sensor 141 near the surface air bag is less than the second threshold value, it is determined that the area in the seat profile corresponding to the pressure sensor 141 is not sufficient to make the seat profile pressure distribution uniform, and therefore, the surface air bag near the pressure sensor 141 is inflated to make the seat profile pressure distribution uniform.

[0083] The second control sub-unit is configured to inflate the surface air bag connected to the air pump when the pressure collected by the pressure sensor 141 near the surface air bag is less than the second threshold value, and the first threshold value is less than the second threshold value.

[0084] In the embodiment, the second control sub-unit can be an air pump connected to the surface air bag. When the air pump receives a signal from the second determining sub-unit indicating that the pressure collected by the pressure sensor 141 near the surface air bag is less than the second threshold value, the air pump inflates the surface air bag near the pressure sensor 141 until it receives a signal from the second determining sub-unit indicating that the pressure detected by the pressure sensor 141 near the surface air bag is equal to or greater than the second threshold value.

[0085] In combination with the above embodiments, in some embodiments, the seat pneumatic adjustment unit 12 further comprises:

[0086] The seat hardness adjustment sub-unit is configured to determine the value of the first threshold value and / or the second threshold value corresponding to the desired seat hardness level.

[0087] In the embodiment, the seat hardness adjustment sub-unit can be a microcontroller. The seat hardness level can include three levels: hard, standard, and soft. The value of the first threshold value and / or the second threshold value corresponding to different seat hardness levels can be calibrated by experimental data of pressure distribution of users with different body types.

[0088] Optionally, in some embodiments, the system can further include a manual adjustment unit, enabling the user to manually fine-tune the seat posture and the inflation state of the deep air bag 122 of the certain surface air bag based on personal preference after the system automatically completes the seat posture adjustment and the seat pneumatic adjustment.

[0089] Wherein, the manual adjustment unit adjusts the seat posture and the air bag (air bag) inflation state by manual mode, which is prior art and not described in detail here.
