[0059] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0060] Referring to Figure 1 as shown, the seat system 10 of the present application includes a seat body 100, which is for a user to sit on and has a zero-gravity seat mode.

[0061] Specifically, the seat body 100 includes: a seat backrest 110, a seat cushion 120, and a seat leg rest 130. Among them, the seat backrest 110 is at least used to support the user's back; the seat cushion 120 is at least used to support the user's buttocks; the seat leg rest 130 is at least used to support the user's legs. The seat backrest 110, the seat cushion 120, and the seat leg rest 130 can be movably connected so that they can move relative to each other to achieve the zero-gravity seat mode.

[0062] Referring to Figure 1 as shown, Figure 1 shows the attitude of a seat body 100 in the zero-gravity seat mode. In the present application, the usage states formed by the seat backrest 110, the seat cushion 120, and the seat leg rest 130 at different positions and angles are defined as the attitudes of the seat body 100; the position of the seat body 100 relative to the compartment of the vehicle 1 is defined as the position of the seat body 100. Specifically, the seat body 100 can be adjusted in position in two mutually perpendicular directions, such as front-back and up-down position adjustments.

[0063] Referring to Figure 1 as shown, the angles formed by the extending directions of the seat backrest 110, the seat cushion 120, and the seat leg rest 130 in the side view plane of the vehicle 1 with the reference direction of the vehicle 1 are respectively defined as the backrest angle a, the seat cushion angle b, and the leg rest angle c.

[0064] It should be noted that since the seat backrest 110, the seat cushion 120, and the seat leg rest 130 are all three-dimensional entities, the length direction of the projected contour of them in the side view plane can be used as their extending directions. Of course, the supporting surfaces provided by the seat backrest 110, the seat cushion 120, and the seat leg rest 130 can also be used as their extending directions. The backrest angle a, the seat cushion angle b, and the leg rest angle c are mainly used to reflect the angles of the back, the thighs, and the calves supported by them relative to the reference direction of the vehicle 1. As a specific solution, the reference direction of the vehicle 1 can be the front-back direction of the vehicle 1.

[0065] Referring to Figure 2 as shown, the seat system 10 of the present application further includes: a controller 200. The controller 200 can control the position and / or attitude of the seat body 100 according to the speed of the vehicle 1.

[0066] In this way, when the speed of the vehicle 1 changes, the controller 200 can control the posture of the seat body 100, so that the user can sit in a relatively safe posture; or, the controller 200 can control the position of the seat body 100 to make the user in the area protected by the seat belt and airbag. Of course, the controller 200 of the present application can adjust both the posture and the position of the seat body 100.

[0067] As a specific solution, the vehicle speed of the vehicle 1 can be divided into a first speed range, a second speed range, and a third speed range from low to high; and different postures of the seat body 100 are configured for each speed range.

[0068] When the speed of the vehicle 1 is in the first speed range, the controller 200 controls the seat backrest 110, the seat cushion 120, and the seat leg rest 130 to be in the first backrest angle range, the first seat cushion angle range, and the first leg rest angle range respectively.

[0069] Similarly, when the speed of the vehicle 1 is in the second speed range, the controller 200 controls the seat backrest 110, the seat cushion 120, and the seat leg rest 130 to be in the second backrest angle range, the second seat cushion angle range, and the second leg rest angle range respectively.

[0070] When the speed of the vehicle 1 is in the third speed range, the controller 200 controls the seat backrest 110, the seat cushion 120, and the seat leg rest 130 to be in the third backrest angle range, the third seat cushion angle range, and the third leg rest angle range respectively.

[0071] The first backrest angle range is less than the second backrest angle range; the second backrest angle range is less than the third backrest angle range.

[0072] The first seat cushion angle range is less than the second seat cushion angle range; the second seat cushion angle range is less than the third seat cushion angle range.

[0073] The first leg rest angle range is less than the second leg rest angle range; the second leg rest angle range is less than the third leg rest angle range.

[0074] It should be noted that in this application, one numerical range being less than another numerical range means that the maximum value of one numerical range is less than the minimum value of the other numerical range. For example, "the first backrest angle range is less than the second backrest angle range" means that the maximum angle of the first backrest angle range is less than the minimum angle of the second backrest angle range. In this application, one numerical range being greater than another numerical range means that the minimum value of one numerical range is greater than the maximum value of the other numerical range. For example, "the second seat cushion angle range is greater than the first seat cushion angle range" means that the minimum value of the second seat cushion angle range is greater than the maximum value of the first seat cushion angle range. The above explanations apply to the size relationships of the numerical ranges in this application and will not be elaborated below.

[0075] As a specific solution, when the vehicle 1 is stationary or at a low speed (speed less than 5 km / h), the backrest angle a, the seat cushion angle b, and the leg rest angle c can all be adjusted to a relatively small angle (such as below 8°) so as to be used in a relatively comfortable lying flat posture (the seat body 100 is in the zero-gravity seat mode); When the vehicle 1 is at a medium-low speed (speed from 5 km / h to 40 km / h), the seat cushion angle b can be adjusted to be between 8° and 35°. By raising the seat cushion 120 of the seat, when the vehicle 1 collides, since the seat cushion 120 can block the forward movement of the occupant and can also take into account the comfort requirements of the occupant.

[0076] Refer to Figure 3 As shown, a definite numerical relationship can be established between the seat cushion angle b and the vehicle 1. For example, Figure 3 As shown in the linear relationship, as the vehicle speed increases, the seat cushion angle b increases proportionally, which can not only meet the requirements of riding comfort but also ensure the safety of the occupant during a collision.

[0077] That is, when the speed of the vehicle 1 is in the third speed range, the controller 200 controls the angle of the seat cushion 120 of the seat to be adapted to the speed of the vehicle 1.

[0078] When the vehicle 1 is at a medium-high speed with a speed greater than 40 km / h, if the user is in a lying flat state, then when the vehicle 1 is collided, the occupant will leave the seat body 100 and rush forward, and the seat belt will strangle the user.

[0079] At this time, an auxiliary knee airbag 500 is needed to ensure the riding safety of the user in the zero-gravity seat mode. Correspondingly, the controller 200 needs to adjust the position of the seat body 100 so that the user moves to the area that can be protected by the knee airbag 500, and appropriately adjust the posture of the seat body 100 with the user's knowledge or consent. On the one hand, it makes the user's knees fit the knee airbag 500, and on the other hand, it adjusts the user's sitting posture to avoid the user lying too flat and causing the safety measures to fail.

[0080] Refer toFigure 4 As shown, in some embodiments of the present application, the seat system 10 includes: a knee airbag 500; the knee airbag 500 is at least used to protect the user's knees; the controller 200 adjusts the position of the seat body 100 at least according to the posture of the seat body 100 to adapt to the position of the knee airbag 500.

[0081] As a specific solution, the knee airbag 500 can be arranged below the steering wheel or at other positions in the vehicle compartment corresponding to the front of the seat body 100.

[0082] Referring to Figure 1 As shown, when the front of the vehicle 1 is collided, after the occupant leaves the zero-gravity seat forward due to inertia, the occupant's knees just encounter the knee airbag 500. The knee airbag 500 has the functions of buffering the collision impact and restricting the occupant's displacement. In order to ensure that the knee airbag 500 achieves the best protection effect and prevent the occupant from rushing forward and leaving the position during a frontal collision, a better way is that after the knee airbag 500 is deployed, the knee airbag 500 just adheres to the occupant's knees, minimizing the occupant's displacement.

[0083] Specifically, when the backrest angle a is greater than the preset backrest angle threshold, the controller 200 adjusts the position of the seat body 100 according to the user's height and the seat cushion. The fact that the backrest angle a is greater than the preset backrest angle threshold indicates that the seat body 100 is in the zero-gravity seat mode. At this time, the controller 200 calls the data of the current user's height in the database (pre-detected or input) and calculates the position of the user's knees at least in combination with the current seat cushion angle b.

[0084] As an alternative solution, when the leg rest angle c is relatively large, the controller 200 also needs to calculate the position of the user's knees in combination with the leg rest angle c when calculating.

[0085] As an alternative solution, the controller 200 also needs to calculate the position of the user's knees in combination with the position of the seat body 100.

[0086] It should be noted that the controller 200 controls the seat body 100 to adjust its posture so as to change the user's posture, which is only to roughly place the user's part in a general area. For example, controlling the seat body 100 to change the position of the user's knees to align with the knee airbag 500 is only to place the user's knees in the area where the knee airbag 500 is located. That is, the state of the control body is determined to be achievable, while the user's posture has a certain degree of uncertainty.

[0087] Referring to Figure 1As shown, in some embodiments of the present application, knee airbag 500 has an airbag contact surface for contacting at least the user's knee. The angle of the airbag contact surface is defined as airbag angle d. It should be understood that the airbag contact surface angle refers to the angle formed between the extension direction of the airbag contact surface and the reference direction of vehicle 1 when viewed from the side of vehicle 1. The airbag contact surface can be configured as a flat surface or a curved surface. When the airbag contact surface is a curved surface, the extension direction of the airbag contact surface refers to the direction of the maximum connecting line of the curved surface.

[0088] As a specific solution, in order to avoid the safety risks brought by the uncertainty of the user's posture as much as possible, in the zero-gravity seat state of the present application, the controller 200 controls the seat leg rest 130 so that the leg rest angle c is smaller than the airbag angle d.

[0089] More specifically, the leg support angle c and the airbag angle d satisfy the following relationship: d-25°<c<d-15°.

[0090] In this way, the knee airbag 500 and the seat leg support 130 can better protect the user's legs from both the front and rear sides.

[0091] Reference Figure 2 As shown, in some embodiments of the present application, the seat system 10 also includes: a leg detection device 300 and a human-computer interaction device 400; wherein, the leg detection device 300 is used to detect the user's leg posture; the human-computer interaction device 400 is used to realize human-computer interaction with the user; when the leg posture detected by the leg detection device 300 does not meet the preset conditions and the speed of the vehicle 1 is greater than the preset vehicle speed threshold, the controller 200 controls the human-computer interaction device 400 to remind the user.

[0092] In this way, the user can be proactively reminded of safety risks, thereby enabling the user to proactively adjust the seat body 100 to a relatively safe posture.

[0093] As a specific solution, the leg detection device 300 can be configured as a camera or a pressure sensor, and the human-computer interaction device 400 can be configured as a display screen or a microphone.

[0094] Reference Figure 1 and Figure 2 As shown, in some embodiments of the present application, when the angle of the seat back 110 is less than a preset backrest angle threshold and the speed of the vehicle 1 is greater than a preset vehicle speed threshold, the controller 200 adjusts the angle of the seat back 110 according to the speed of the vehicle 1.

[0095] This can proactively provide safety protection, thereby further ensuring the safety of personnel.

[0096] As an alternative, when the adjustment mode of the seat system 10 is in a preset mode, the controller 200 automatically adjusts the angle of the seat back 110. The adjustment mode includes: an automatic adjustment mode and a manual adjustment mode; in the automatic adjustment mode, the controller 200 automatically adjusts the seat system 10; in the manual adjustment mode, the user manually adjusts the seat system 10; the preset mode is the automatic adjustment mode. That is, in the automatic mode, the controller 200 can actively adjust according to the vehicle speed.
