[0086] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0087] Reference Figure 1 As shown, the seat system 10 of this application includes a seat body 100, which is used for a user to sit on and has a zero-gravity seat mode.
[0088] Specifically, the seat body 100 includes: a seat back 110, a seat cushion 120, and a seat leg rest 130. The seat back 110 provides at least support for the user's back; the seat cushion 120 provides at least support for the user's buttocks; and the seat leg rest 130 provides at least support for the user's legs. The seat back 110, seat cushion 120, and seat leg rest 130 can be movably connected, allowing them to move relative to each other to achieve a zero-gravity seating mode.
[0089] Reference Figure 1 As shown, Figure 1 The image shows the posture of a seat body 100 in zero-gravity seat mode. In this application, the posture of the seat body 100 is defined as the usage state formed by the seat back 110, seat cushion 120 and seat leg rest 130 at different positions and angles. The position of the seat body 100 relative to the vehicle compartment of the vehicle 1 is defined as the position of the seat body 100. Specifically, the seat body 100 can be adjusted in two mutually perpendicular directions, such as front-back and up-down position adjustments.
[0090] Reference Figure 1 As shown, the angles formed by the extension directions of the seat back 110, seat cushion 120, and seat leg rest 130 in the side view plane of the vehicle 1 and the reference direction of the vehicle 1 are defined as the back angle a, the seat cushion angle b, and the leg rest angle c, respectively.
[0091] It should be noted that since the seat back 110, seat cushion 120, and seat leg rest 130 are all three-dimensional entities, the length direction of their projected outlines in the side view plane can be taken as their extension direction. Alternatively, the support surface provided by the seat back 110, seat cushion 120, and seat leg rest 130 can be taken as their extension direction. The backrest angle a, cushion angle b, and leg rest angle c are mainly to represent the angles of the back, thighs, and lower legs supported by them relative to the reference direction of vehicle 1. Specifically, the reference direction of vehicle 1 can be the front-rear direction of vehicle 1.
[0092] Reference Figure 2 As shown, the seat system 10 of this application also includes a controller 200. The controller 200 can control the position and / or posture of the seat body 100 according to the speed of the vehicle 1.
[0093] In this way, when the speed of vehicle 1 changes, controller 200 can control the posture of seat body 100 to allow the user to sit in a safer position; or, controller 200 can control the position of seat body 100 to place the user in an area protected by seat belts and airbags. Of course, the controller 200 of this application can adjust both the posture and position of seat body 100.
[0094] As a specific solution, the vehicle speed of 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 can be configured for each speed range.
[0095] When the speed of vehicle 1 is in the first speed range, controller 200 controls the seat back 110, seat cushion 120 and seat leg rest 130 to be in the first backrest angle range, the first cushion angle range and the first leg rest angle range, respectively.
[0096] Similarly, when the speed of vehicle 1 is in the second speed range, controller 200 controls the seat back 110, seat cushion 120 and 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.
[0097] When the speed of vehicle 1 is in the third speed range, controller 200 controls the seat back 110, seat cushion 120 and 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.
[0098] The first backrest angle range is smaller than the second backrest angle range; the second backrest angle range is smaller than the third backrest angle range.
[0099] The first seat angle range is smaller than the second seat angle range; the second seat angle range is smaller than the third seat angle range.
[0100] The angle range of the first leg support is smaller than that of the second leg support; the angle range of the second leg support is smaller than that of the third leg support.
[0101] It should be noted that, in this application, "one numerical interval is less than another numerical interval" means that the maximum value of one numerical interval is less than the minimum value of another numerical interval; for example, "the first backrest angle interval is less than the second backrest angle interval" means that the maximum angle of the first backrest angle interval is less than the minimum angle of the second backrest angle interval. Similarly, "one numerical interval is greater than another numerical interval" means that the minimum value of one numerical interval is greater than the maximum value of another numerical interval; for example, "the second seat cushion angle interval is greater than the first seat cushion angle interval" means that the minimum value of the second seat cushion angle interval is greater than the maximum value of the first seat cushion angle interval. The above explanation applies to all numerical interval relationships in this application, and will not be elaborated further below.
[0102] As a specific solution, when vehicle 1 is stationary or at low speed (less than 5 km / h), the backrest angle a, seat cushion angle b, and leg rest angle c can all be adjusted to a smaller angle (e.g., below 8°) to allow for a more comfortable reclining posture (with the seat body 100 in zero-gravity seat mode).
[0103] When vehicle 1 is at a low to medium speed (5 km / h to 40 km / h), the seat cushion angle b can be adjusted to between 8° and 35°. By raising the seat cushion 120, in the event of a collision, the seat cushion 120 can prevent the occupants from moving forward while also ensuring the comfort of the occupants.
[0104] Reference Figure 3 As shown, the seat angle b can be made to have a definite numerical relationship with vehicle 1, for example... Figure 3 The linear relationship shown indicates that the seat angle b increases proportionally with vehicle speed, which satisfies both ride comfort requirements and ensures occupant safety during a collision.
[0105] That is, when the speed of vehicle 1 is in the third speed range, the controller 200 controls the angle of the seat cushion 120 to match the speed of vehicle 1.
[0106] When vehicle 1 is at a medium to high speed of more than 40 km / h, if the user is in a lying position, the occupant will be thrown forward from the seat body 100 when vehicle 1 is hit by a collision, and the seat belt will restrain the user.
[0107] At this point, an auxiliary knee airbag 500 is needed to ensure the user's safety while seated in zero-gravity mode. Accordingly, the controller 200 needs to adjust the position of the seat body 100 to move the user to an area protected by the knee airbag 500, and, with the user's knowledge or consent, appropriately adjust the posture of the seat body 100. This ensures the user's knees are aligned with the knee airbag 500, and also adjusts the user's sitting posture to prevent excessive reclining, which could render the safety measures ineffective.
[0108] Reference Figure 4 As shown, in some embodiments of this application, the seat system 10 includes: a knee airbag 500; the knee airbag 500 is used to protect the user's knee; and the controller 200 adjusts the position of the seat body 100 according to the posture of the seat body 100 to adapt to the position of the knee airbag 500.
[0109] As a specific solution, the knee airbag 500 can be installed below the steering wheel, or in front of other corresponding seat bodies 100 in the passenger compartment.
[0110] Reference Figure 1 As shown, when vehicle 1 is subjected to a frontal collision, the occupant, due to inertia, leaves the zero-gravity seat forward, and their knees just touch the knee airbag 500. The knee airbag 500 serves to cushion the collision impact and restrict the occupant's movement.
[0111] To ensure the best protective effect of the knee airbag 500 and prevent the occupant from being thrown forward during a frontal collision, the preferred method is to ensure that the knee airbag 500, after deployment, fits precisely against the occupant's knee, minimizing occupant displacement.
[0112] Specifically, when the backrest angle 'a' is greater than a 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. A backrest angle 'a' greater than the preset backrest angle threshold indicates that the seat body 100 is in zero-gravity seat mode. At this time, the controller 200 calls the current user height data (pre-detected or entered) from the database and calculates the position of the user's knees, at least in conjunction with the current seat cushion angle 'b'.
[0113] As an optional solution, when the leg support angle c is large, the controller 200 also needs to calculate the position of the user's knees in conjunction with the leg support angle c.
[0114] As an optional solution, the controller 200 also needs to calculate the position of the user's knees based on the position of the seat body 100.
[0115] It should be noted that when the controller 200 controls the seat body 100 to adjust its posture and thus change the user's posture, it only roughly positions the user's body parts within a general area. For example, when controlling the seat body 100 to change the position of the user's knees to align with the knee airbag 500, it only places the user's knees within the area where the knee airbag 500 is located. In other words, the state of the controller body is definite and controllable, while the user's posture has a certain degree of uncertainty.
[0116] Reference Figure 1 As shown, in some embodiments of this application, the knee airbag 500 has at least one airbag contact surface for contacting the user's knee. The angle of the airbag contact surface is defined as the airbag angle d. It can be understood that the angle of the airbag contact surface refers to the angle formed by the extending direction of the airbag contact surface and the reference direction of the vehicle 1 in the side view plane of the vehicle 1. The airbag contact surface can be constructed as a plane or as a curved surface. When the airbag contact surface is curved, the extending direction of the airbag contact surface refers to the direction of the maximum connecting line of the curved surface.
[0117] As a specific solution, in order to minimize the safety risks caused by the uncertainty of the user's posture, in the zero-gravity seat state of this application, the controller 200 controls the seat leg rest 130 so that the leg rest angle c is less than the airbag angle d.
[0118] More specifically, the leg support angle c and the airbag angle d satisfy the following relationship: d-25°<c<d-15°.
[0119] This allows the knee airbag 500 and the seat leg support 130 to provide better protection for the user's legs from both the front and rear sides.
[0120] Reference Figure 2 As shown, in some embodiments of this application, the seat system 10 further 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 achieve 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.
[0121] This allows the system to proactively alert users to safety risks, prompting them to adjust the seat to a relatively safe position.
[0122] As a specific embodiment, the leg detection device 300 can be configured as a camera or a pressure sensor. The human-computer interaction device 400 can be configured as a display screen or a microphone.
[0123] Reference Figure 1 and Figure 2As shown, in some embodiments of this 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.
[0124] This allows for proactive safety measures, thereby further ensuring the safety of personnel.
[0125] As an optional feature, the controller 200 automatically adjusts the angle of the seat back 110 when the adjustment mode of the seat system 10 is in a preset mode. The adjustment modes include: automatic adjustment mode and manual adjustment mode; in automatic adjustment mode, the controller 200 automatically adjusts the seat system 10; in manual adjustment mode, the user manually adjusts the seat system 10; the preset mode is automatic adjustment mode. That is, in automatic mode, the controller 200 can actively adjust according to the vehicle speed.
[0126] Reference Figure 4 As shown, the control method of this application mainly includes:
[0127] S1: Control the position and / or posture of the seat body 100 according to the speed of the vehicle 1.
[0128] Specifically, step S1 includes at least:
[0129] When the speed of vehicle 1 is in the first speed range, the seat back 110, seat cushion 120 and seat leg rest 130 are controlled to be in the first backrest angle range, the first cushion angle range and the first leg rest angle range, respectively.
[0130] Similarly, when the speed of vehicle 1 is in the second speed range, the seat back 110, seat cushion 120 and seat leg rest 130 are controlled to be in the second backrest angle range, the second seat cushion angle range and the second leg rest angle range, respectively.
[0131] When the speed of vehicle 1 is in the third speed range, control the seat back 110, seat cushion 120 and 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.
[0132] The first backrest angle range is smaller than the second backrest angle range; the second backrest angle range is smaller than the third backrest angle range.
[0133] The first seat angle range is smaller than the second seat angle range; the second seat angle range is smaller than the third seat angle range.
[0134] The angle range of the first leg support is smaller than that of the second leg support; the angle range of the second leg support is smaller than that of the third leg support.
[0135] Reference Figure 5 As shown, in some embodiments of this application, step S1 may include:
[0136] S101: Start the program; Proceed to step S102.
[0137] S102: Obtain the backrest angle a; Proceed to step S103.
[0138] S103: Determine whether the backrest angle a is greater than the first preset backrest angle threshold; if yes, proceed to step S104; otherwise, proceed to step S101.
[0139] S104: Obtain user height data; Proceed to step 105. Generally, user height data is retrieved from historical data in the database; however, it can also be detected or entered in real time.
[0140] S105: Obtain the seat angle b; Proceed to step 106. It should be noted that steps S104 and S105 can be performed simultaneously.
[0141] S106: Adjust the posture or position of the seat body 100. Of course, both the posture and position of the seat body 100 can be adjusted.
[0142] In this way, steps S101 to S106 can ensure that the user's knee is within the protection range of the knee airbag 500; more specifically, the user's knee is located 1mm to 10mm below the knee airbag 500.
[0143] Reference Figure 6 In some embodiments of this application, step S1 may include:
[0144] S201: Obtain the backrest angle a.
[0145] S202: Determine whether the backrest angle a is less than the second preset backrest threshold; if yes, proceed to step 203; otherwise, proceed to step 201.
[0146] S203: Obtain vehicle speed; Proceed to step S204.
[0147] S204: Determine whether the vehicle speed is greater than the first preset vehicle speed threshold; if yes, proceed to step S205; otherwise, proceed to step S201.
[0148] S205: Obtain the current adjustment mode of the seat system 10; proceed to step S206.
[0149] S206: Determine whether the current adjustment mode is in automatic adjustment mode; if yes, proceed to step S207; otherwise, proceed to step S208.
[0150] S207: Adjust the posture or position of the seat body 100. Of course, both the posture and position of the seat body 100 can be adjusted.
[0151] S208: Issue a reminder to the user to adjust the seat body 100. More specifically, issue a reminder to the user to adjust the backrest angle a.
[0152] As a specific solution, the first preset backrest angle threshold and the second preset backrest angle threshold can be different angle values or the same angle value; as a specific solution, both the first preset backrest angle threshold and the second preset backrest angle threshold are 35°.
[0153] As a specific solution, step S208 can use the multimedia device of vehicle 1 to remind the user, for example, through images from the vehicle's infotainment system, sounds from the audio system, or a combination thereof. When reminding the user, the device can either inform the user of suitable seat parameters, allowing the user to adjust them themselves, or remind the user to switch to automatic adjustment mode so that the seat system 10 can adjust automatically according to driving conditions, etc.
[0154] Reference Figure 7 As shown, in some embodiments of this application, step S1 may include:
[0155] S301: Obtain the airbag angle d; Proceed to step S302.
[0156] Generally speaking, the airbag angle d is already in the database; because the knee airbag 500 does not deploy when the vehicle 1 is driving normally; therefore, the airbag angle d, which is related to the position and shape of the knee airbag 500 after deployment, is often pre-stored in the database according to the knee airbag 500 and the model of the vehicle 1 when the knee airbag 500 is installed.
[0157] S302: Obtain the leg support angle c; Proceed to step 303.
[0158] S303: Determine whether the airbag angle d and leg support angle c meet the preset conditions.
[0159] Specifically, the preset condition is that the leg support angle c and the airbag angle d satisfy the following relationship: d-25°<c<d-15°. If so, proceed to step 305; otherwise, proceed to step 304.
[0160] S304: Adjust the leg support angle c; Proceed to step S302.
[0161] S305: End.
[0162] Reference Figure 8 As shown, in some embodiments of this application, step S1 may include:
[0163] S401: Obtain the lower leg posture; Proceed to step 402.
[0164] S402: Determine if the lower leg posture is abnormal; if so, proceed to step S403; otherwise, proceed to step S401.
[0165] S403: Obtain vehicle speed; Proceed to step S404.
[0166] S404: Determine whether the vehicle speed is greater than the second preset vehicle speed threshold; if yes, proceed to step S405; otherwise, proceed to step S401.
[0167] S405: Issues a reminder to the user to adjust the seat body 100. More specifically, it issues a reminder to the user to adjust their leg posture.
[0168] As an optional option, the first preset vehicle speed threshold and the second preset vehicle speed threshold can be different speed values or the same speed value. As a specific option, both the first preset vehicle speed threshold and the second preset vehicle speed threshold are 40km / h.
[0169] Specifically, the leg detection device 300 can detect the lower leg posture; alternatively, the entire leg posture can be detected as a criterion. As an option, the leg detection device 300 can be configured as a camera to acquire data about the lower leg posture through images; the leg detection device 300 can also be configured as a pressure sensor to... Figure 9 The pressure distribution map shown is based on data collected about lower leg posture. Figure 9 As shown, the pressure distribution map can determine whether the user is currently in a position with both legs flat or crossed. When the user is in a position with their legs crossed, a concentrated area will appear in the pressure distribution map.
[0170] Reference Figure 10 As shown, without the knee airbag 500, the user's feet extend forward, making them vulnerable to injury from the vehicle 1 and any intruding objects. The user's hips also disengage from the seatbelt, potentially causing injury. However, with the knee airbag 500, its application to the user's lower leg and knee restricts movement. The user's knees are held against the airbag, and the hips are restrained by the seatbelt, preventing additional injury and effectively protecting the user's collision safety when using the zero-gravity seat.
