Description

Technical Field

[0001] The present application relates to the technical field of automobile parts, and in particular to a system, method, device and medium for adaptive adjustment of seats. Background Art

[0002] With the rapid development of the automobile industry, users have higher and higher demands for automobile comfort, intelligence, scenario-based and personalization. As seats are an important component that reflects automobile comfort, the comfort of seats also needs to be continuously improved.

[0003] At present, in order to improve user comfort, some seats are equipped with a zero-gravity mode. Zero gravity means that the seat back is reclined to 120°~130°, and the leg rest is raised at the same time so that the knees are slightly higher than the heart, forming a "neutral posture" similar to that of astronauts in a zero-gravity environment. Through ergonomic design, the seat surface can adapt to the human body, evenly distributing the body weight to the back, buttocks, and legs, reducing pressure on the spine and joints.

[0004] The existing seat shapes are designed and calibrated based on standard human body models, but the human body characteristics (such as height and weight) of different users may vary greatly. The existing seat shapes are difficult to adapt to some user groups that are quite different from the standard human body models. In addition, in order to adapt to the human body characteristics of different users, the seat posture often needs to be adjusted. There are differences in the more comfortable seat postures corresponding to different users. When the seat posture changes, the pressure distribution of the human body on the seat will also change.

DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0049] The features of the terms "first" and "second" in the specification and claims of this application may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, the meaning of "plurality" is two or more.

[0050] For the sake of convenience, the middle supporting area of ​​the seat is defined as the seat center, and the protruding areas on both sides of the seat are defined as seat wings. The center refers to the middle area of ​​the seat used to support the human body, and the wings refer to the protruding areas of the seat on both sides of the human body. For example, the seat back center refers to the middle area of ​​the backrest supporting the back of the human body, and the backrest wings refer to the protruding areas of the backrest on both sides of the upper body of the human body. The seat cushion center refers to the middle area of ​​the seat cushion supporting the buttocks and legs of the human body, and the seat cushion wings refer to the protruding areas of the seat cushion on both sides of the lower body of the human body.

[0051] refer to Figure 1 , Figure 1 This is a schematic diagram of a control system of a motor actuator according to an embodiment of the present application. Figure 1As shown, the system 100 includes: a feature detection unit, a seat posture adjustment unit 11, a pressure detection unit, and a seat pneumatic adjustment unit 12, wherein the pressure detection unit includes a plurality of pressure sensors 141, and the seat pneumatic adjustment unit 12 includes a plurality of first seat inflation mechanisms distributed between a seat cover 125 and a seat frame 111, wherein the first seat inflation mechanism includes a first surface airbag 121, a first foam 123, and a deep airbag 122; the seat frame 111, the deep airbag 122, the first foam 123, the first surface airbag 121, the pressure sensor 141, and the seat cover 125 are sequentially arranged along the direction from inside to outside of the seat 1, and the first surface airbag 121 is arranged in sequence. 1 and the deep air bag 122 are respectively connected to an air pump; a feature detection unit, used to detect the user's feature parameters, the feature parameters including height and weight, and / or fatigue level; a seat posture adjustment unit 11, used to adjust the seat to the optimal seat posture corresponding to the feature parameters according to the feature parameters; a pressure detection unit, used to collect the human body pressure distribution of the user on the seat 1 after the seat posture adjustment is completed through a plurality of pressure sensors 141; a seat pneumatic adjustment unit 12, used to adjust the inflation state of the first surface airbag 121 and the deep air bag 122 of each first seat inflation mechanism according to the collected human body pressure distribution, so as to make the seat surface pressure distribution of the user sitting on the seat 1 uniform.

[0052] In this embodiment, the feature detection unit may include an external camera set on the vehicle, an internal camera and a weight detection system 142 set under the seat, wherein the height of a person is determined by detecting through the external camera, the degree of fatigue of a person is identified by detecting through the internal camera, and the weight of a person is obtained by the weight detection system 142.

[0053] In this embodiment, if Figure 2 and Figure 3 As shown, the seat posture adjustment unit 11 in the seat 1 may include a seat frame 111, a headrest adjustment mechanism 112, and a leg rest adjustment mechanism 113. The coordination of the above components is a conventional technical means in the field and will not be elaborated here. Based on the detection results of the feature detection unit, a big data algorithm is used to accurately calculate the seat posture with better user sensation, and the seat posture is adjusted to the corresponding seat posture through the coordination of the various components of the above seat posture adjustment unit 11. For example, the seat posture is adjusted according to the height and weight of the user so that the seat posture adapts to the user's body shape; or, the seat posture is adjusted according to the user's fatigue so that the user's fatigue 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 adapts to the user's body shape, and then the seat posture is slightly adjusted according to the user's fatigue so that the user's fatigue can be relieved as needed.

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

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

[0056] In this embodiment, the seat pneumatic adjustment unit 12 is used to adjust the inflation state of the first surface airbag 121 and the deep airbag 122 of each first seat inflation mechanism according to the collected human body pressure distribution, wherein the specification of the deep airbag 122 is much larger than that of the first surface airbag 121. When the deep airbag 122 is inflated, the seat profile can have a large change. Therefore, by adjusting the inflation state of the deep airbag 122, the seat profile can be greatly adjusted, thereby adjusting the seat profile to a state close to the user's body shape; the surface airbags are smaller in specification and are distributed under the seat profile. Based on the collected human body pressure distribution, the seat profile pressure distribution when the user sits on the seat can be determined. Each surface airbag can be fine-tuned based on the pressure distribution to make the seat profile pressure distribution uniform when the user sits on the seat, provide the user with comfortable support and wrapping feeling, and improve the user's comfort on the seat.

[0057] To summarize, the present 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 through the cooperation of the pressure detection unit and the seat pneumatic adjustment unit 12, the seat after the seat posture adjustment can have a surface that adapts to the user, thereby improving the user's comfort.

[0058] The entire system can adapt itself according to the status of different users, increasing the number of adapted users, and the system as a whole is automatically adjusted, avoiding safety hazards caused by manual adjustment by users; the system's overall posture and profile adjustment will make the seat more comfortable, with stronger support and wrapping.

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

[0060] In combination with the above embodiments, in some implementations, the seat pneumatic adjustment unit 12 also includes a second seat inflation mechanism distributed between the seat cover 125 and the seat frame 111, and the second seat inflation mechanism includes a second surface airbag and a second foam; the seat frame 111, the second foam, the second surface airbag, the pressure sensor 141 and the seat cover 125 are arranged in sequence from the inside to the outside of the seat, and the second surface airbag is connected to an air pump.

[0061] In the present embodiment, the present applicant has found that only one layer of inflatable parts is provided under the seat profile. If the inflatable parts are larger in size, the volume change of the inflatable parts after inflation is larger. When the inflatable parts are inflated and contact the human body, the pressure on the human body is more concentrated, and the human body will have a stronger sense of foreign body, especially in the areas where the human body is subjected to greater force, which affects the user's comfort when riding. If the inflatable parts are smaller in size, the volume change of the inflatable parts after inflation is smaller, and the body characteristics (such as height and weight) of different users may vary greatly. When users with different body characteristics sit on the seat, the seat profile may be difficult to adapt, and the inflatable parts with smaller volume change cannot guarantee contact with the human body or provide sufficient pressure.

[0062] Therefore, the present application provides another embodiment, in which a double-layer inflatable part is set in the area of ​​the seat surface that is difficult to adapt to users with different body characteristics (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), so that the specifications of the deep air bag are larger, and the specifications of the surface air bag are smaller. The seat surface can be adjusted to a greater extent by inflating the deep air bag 122, and then a small adjustment is made through the surface air bag to adapt to different body characteristics. Some areas of the seat do not need to adjust the surface too much, such as the headrest part of the seat (there will not be too much difference in the size of the head of users of different body shapes, so the headrest part of the seat does not need to adjust the surface too much), and the surface air bag alone can make the surface of the corresponding area of ​​the seat adapt to different users.

[0063] In combination with the above embodiments, in some implementations, Figure 4 As shown, the plurality of first seat inflation mechanisms are respectively arranged in the backrest background, backrest side wings, seat cushion background, seat cushion side wings and leg rest of the seat, and the second seat inflation mechanism is arranged in the headrest portion of the seat, thereby saving costs.

[0064] In combination with the above embodiments, in some implementation schemes, the diameters of the first surface airbag 121 and the second surface airbag are both 10 to 20 mm, and all the surface airbags are relatively densely arranged under the seat profile.

[0065] In combination with the above embodiments, in some implementations, the deep air bag 122 is specifically arranged in the seat, which may be:

[0066] In the backrest of the chair, the number of the deep air bags 122 is at least 3 (4 are shown in the figure, of which the two at the top support the upper back of the human body at the same time). The three deep air bags 122 are respectively arranged in the backrest corresponding to the areas of the upper back, waist and lumbosacral part of the human body, so as to make the contour of the backrest adapt to the curve of the human spine through the support of the three deep air bags 122.

[0067] In the seat cushion scene of the chair, the number of the deep air bags 122 is at least 3, and the 3 deep air bags 122 are respectively arranged in the areas of the seat cushion scene corresponding to the buttocks and two thighs of the human body. The gap between the user's thighs and the surface in the seat cushion scene is filled with the support of 2 deep air bags 122 corresponding to the thighs, so that the surface in the seat cushion scene can effectively support the user's thighs.

[0068] There is at least one deep air bag 122 on the backrest side wings, seat cushion side wings and leg rest of the seat, which is used to make the corresponding seat surface close to the user's body surface.

[0069] In combination with the above embodiments, in some implementation schemes, each of the first seat inflation mechanisms includes a plurality of the first surface airbags 121 , and the plurality of the first surface airbags 121 are distributed throughout and abut against the outer surface of the first foam 123 .

[0070] In this embodiment, a plurality of surface airbags may be arranged on the outside of each deep air bag 122. On this basis, each of the first seat inflation mechanisms may be provided with only one deep air bag 122. By inflating a single deep air bag 122, the positions of all the surface airbags on the outside thereof can be adjusted so that the surface airbags can exert pressure on the surface of human bodies of different body shapes.

[0071] In combination with the above embodiments, in some implementation schemes, in the backrest of the seat, the density of the first surface airbags 121 in the lumbar region of the backrest is greater than the density of the first surface airbags 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 support strength requirements of different areas of the human body when sitting. Specifically, the present application finds that when the user sits down, the human lumbar spine requires greater support strength, so the density of the first surface airbag 121 in the corresponding lumbar spine area in the backrest is made greater than the density of the first surface airbag 121 in other areas of the seat to improve the support strength for the user's lumbar spine. Furthermore, the density of the first surface airbag 121 in the lumbar spine area in the backrest can be increased by 20% compared with other areas.

[0073] Optionally, in some embodiments, the first seat inflation mechanism further includes a hard fiber felt 124 , and the hard fiber felt 124 is disposed between the seat frame 111 and the deep air bag 122 .

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

[0075] The first determination subunit is used to determine the relationship between the pressure of the support area corresponding to the deep air bag 122 and the first threshold value according to the collected human body pressure distribution.

[0076] In this embodiment, the first determination subunit may be a microcontroller. The first threshold may be preset or dynamically adjusted based on the seat hardness level selected by the user. When the pressure of the support area corresponding to the deep air bag 122 is less than the first threshold, it is determined that the corresponding area of ​​the seat profile does not contact the human body or does not fit the human body closely enough, and therefore, it is necessary to inflate the deep air bag 122 to adjust the seat profile to fit the human body surface.

[0077] The first control subunit is used to inflate the deep air bag 122 through an air pump connected to the deep air bag 122 when the pressure of the support area corresponding to the deep air bag 122 is less than a first threshold.

[0078] In this embodiment, the first control subunit may be an air pump connected to the deep air bag 122. When the air pump receives a signal from the first determination subunit indicating that the pressure in the support area corresponding to the deep air bag 122 is less than a first threshold, the air pump inflates the deep air bag 122, and stops inflating the deep air bag 122 after receiving a signal from the first determination subunit indicating that the pressure in the support area corresponding to the deep air bag 122 is equal to or greater than the first threshold.

[0079] The pressure detection unit is used to perform secondary collection of the body pressure distribution of the user on the seat after all the deep air bags 122 have been inflated and adjusted through the multiple pressure sensors 141.

[0080] In this embodiment, the pressure detection unit is also used to re-collect the body pressure distribution of the user on the seat through multiple pressure sensors 141 after completing the inflation adjustment of all deep air bags 122. The body pressure distribution collected this time is used to further adjust the inflation of the surface air bags.

[0081] The second determination subunit is used to determine the relationship between the pressure detected by the pressure sensor 141 near the surface airbag and the second threshold value according to the human body pressure distribution collected for the second time, and the surface airbag includes the first surface airbag 121 and the second surface airbag.

[0082] In this embodiment, the second determination subunit may be a microcontroller. The second threshold may be a pressure value when the pressure distribution of the seat profile is uniform, which is derived based on the pressure distribution of the human body detected by the pressure detection 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 airbag is less than the second threshold, it is determined that the area corresponding to the pressure sensor 141 in the seat profile is insufficient to make the pressure distribution of the seat profile uniform, and therefore, the surface airbag near the pressure sensor 141 is inflated to make the pressure distribution of the seat profile uniform.

[0083] The second control subunit is used to inflate the surface airbag through an air pump connected to the surface airbag when the pressure secondarily collected by the pressure sensor 141 near the surface airbag is less than a second threshold, and the first threshold is less than the second threshold.

[0084] In this embodiment, the second control subunit may be an air pump connected to the surface airbag. When the air pump receives a signal from the second determination subunit indicating that the pressure collected for the second time by the pressure sensor 141 near the surface airbag is less than a second threshold, the air pump inflates the surface airbag near the pressure sensor 141, and stops inflating the surface airbag after receiving a signal from the second determination subunit indicating that the pressure detected by the pressure sensor 141 near the surface airbag is equal to or greater than the second threshold.

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

[0086] The seat hardness adjustment subunit is used to determine the first threshold value and / or the second threshold value corresponding to the required seat hardness level according to the hardness level.

[0087] In this embodiment, the seat hardness adjustment subunit may be a microcontroller; the seat hardness level may include three levels: hard, standard, and soft; the first threshold corresponding to different seat hardness levels, and / or the second threshold value may be calibrated by pressure distribution experimental data of users of different body shapes.

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

[0089] Among them, the manual adjustment unit manually adjusts the seat posture and the inflation state of the airbag (air bag) which is the existing technology and will not be described in detail here.

[0090] Optionally, in some embodiments, Figure 6 As shown, the system also includes a seat comfort adjustment unit, which includes a temperature sensor arranged in the vehicle, a heating device 131, a ventilation device 132, a fragrance generator 133, a music rhythm vibrator 134, a music headrest 135, and an atmosphere light 136.

[0091] Based on the same inventive concept, an embodiment of the present application provides a method for adaptively adjusting a seat, which is applied to any of the above-described systems for adaptively adjusting a seat, such as Figure 8 As shown, the method includes:

[0092] Step S1: detecting characteristic parameters of a user by a characteristic detection unit, wherein the characteristic parameters include height and weight, and / or fatigue level;

[0093] Step S2: According to the characteristic parameters, the seat is adjusted to an optimal seat posture corresponding to the characteristic parameters by the seat posture adjustment unit 11;
