Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of automobile seat assembly, in particular to an automobile seat protection system, an automobile interior and an automobile. BACKGROUND

[0002] Nowadays, a safety airbag is usually arranged in front of an automobile seat in a vehicle cabin, and the safety airbag is used to pop up to protect the passengers when the vehicle collides. When the vehicle collides, the driver will move forward and press the safety airbag due to inertia, so that the safety airbag deforms. When the collision is relatively strong, the safety airbag may rebound the passengers backward, and the passengers will re-contact the automobile seat after rebounding.

[0003] At present, the automobile seat includes a seat body and a headrest, and the headrest is usually fixedly connected with the seat.

[0004] However, in the above structure, when the collision is relatively strong, the passengers rebound backward at a high speed. Since the headrest is usually fixedly connected with the seat, the headrest cannot move relative to the seat, which causes a large impact force on the head and neck of the passengers when the passengers contact the headrest. The passengers may be unconscious and unable to perform self-rescue, which has a safety hazard. SUMMARY

[0005] The present disclosure provides an automobile seat protection system, an automobile interior and an automobile, which can solve the technical problems in the related art. The technical solutions are as follows.

[0006] In a first aspect, the present disclosure provides an automobile seat protection system, which comprises a seat assembly, a headrest assembly and a controller.

[0007] The seat assembly is slidably connected with a vehicle cabin base in a vehicle length direction.

[0008] The headrest assembly comprises a driving member, a headrest and a pressure sensor. The fixed part of the driving member is connected with the seat assembly. The headrest is located in a first direction of the driving member, and the first direction is a direction from the vehicle tail to the vehicle head. The pressure sensor is located between the movable part of the driving member and the headrest, and the two ends of the pressure sensor are connected with the movable part and the headrest, respectively.

[0009] The controller is electrically connected with a vehicle accelerometer, the driving member and the pressure sensor, and is configured to: acquire an acceleration value detected by the vehicle accelerometer, acquire a pressure value detected by the pressure sensor, and control the movable part to move in a second direction when the acceleration value is greater than an acceleration threshold value and the pressure value is greater than a pressure threshold value, and the second direction is the reverse direction of the first direction.

[0010] In a possible implementation, the headrest assembly comprises a plurality of driving members and a plurality of pressure sensors.

[0011] The controller is electrically connected with the plurality of driving members and the plurality of pressure sensors respectively, and is configured to: acquire a pressure value detected by each pressure sensor, determine a target speed corresponding to a target numerical range to which the pressure value belongs in a pre-stored corresponding relationship between numerical ranges of pressure values and speeds, and control the movable part to move in the second direction at the target speed.

[0012] In a possible implementation, the plurality of driving members are distributed in a matrix manner.

[0013] In a possible implementation, the seat assembly comprises a linear motor and a seat.

[0014] The stator of the linear motor is connected with the automobile cockpit base, the slide rail of the stator extends in the vehicle length direction, and the sliding block of the linear motor is in sliding connection with the slide rail.

[0015] The seat is connected with the sliding block.

[0016] In a possible implementation, the linear motor is electrically connected with the controller.

[0017] The controller is configured to: control the movable part to move in the second direction at a first speed when the pressure value is greater than a first pressure threshold and less than a second pressure threshold, and control the movable part and the sliding block to move in the second direction at a second speed respectively when the pressure value is greater than or equal to the second pressure threshold, wherein the second pressure threshold is greater than the first pressure threshold, and the second speed is less than the first speed.

[0018] In a possible implementation, the stator is clamped or welded with the automobile cockpit base.

[0019] In a possible implementation, the headrest assembly and the seat assembly are in sliding connection in the vehicle height direction.

[0020] The automobile seat protection system further comprises a camera assembly configured to capture a facial image of a vehicle occupant on the seat assembly and send the facial image to the controller.

[0021] The controller is further configured to: control the headrest assembly to move to a preset position in the vehicle height direction based on a corresponding relationship between the facial image and a pre-stored target facial image.

[0022] In a possible implementation, the headrest comprises an energy-absorbing part, a filling part and a woven mesh cover.

[0023] The energy absorption part has a block structure, the woven mesh cover is sleeved outside the energy absorption part, and the filling part is located between the woven mesh cover and the energy absorption part.

[0024] In a second aspect, the embodiments of the present disclosure provide an automotive interior, which comprises the automotive seat protection system in the first aspect and possible implementation manners thereof.

[0026] The embodiments of the present disclosure have at least the following beneficial effects:

[0027] The embodiments of the present disclosure provide an automotive seat protection system, and the controller is configured to determine that the automobile has a collision when the acceleration detected by the accelerometer is greater than the acceleration threshold value. When the collision occurs, the controller can control the movable part in the headrest assembly to move toward the tail of the automobile from the head of the automobile when the pressure value detected by the pressure sensor is greater than the pressure threshold value. The movable part drives the headrest to move synchronously, so that the contact time of the headrest with the head and neck position of the passenger is increased. Accordingly, the support force of the headrest on the head and neck position of the passenger can be reduced. When the pressure value detected by the pressure sensor is less than or equal to the pressure threshold value, the movable part stops moving. At this time, the support force on the head and neck position is relatively small, so that the head and neck part of the passenger is prevented from being subjected to a large impact force when contacting the headrest, thereby improving the safety performance of the automotive seat protection system.

[0028] It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and cannot limit the present disclosure. BRIEF DESCRIPTION OF DRAWINGS

[0046] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the embodiments of the present disclosure will be further described in detail below with reference to the drawings.

[0047] Unless otherwise defined, technical terms or scientific terms used herein shall have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs.

[0048] Nowadays, at least one airbag is usually arranged in front of each seat in the cockpit of a car, which is used to pop out to contact protect the passengers when the car has a serious collision. It can be understood that, if a serious collision occurs during the driving of the car, the vehicle stops quickly, the airbag pops up, and the passengers move forward under the action of inertia and press the airbag, so that the airbag deforms. When the collision is relatively strong, the airbag may rebound the passengers backward, and the back of the passengers' body will contact the car seat again after the rebound. Or, when the car is parked, a rear car rear-ends, the car moves forward quickly from the stopped state, and the passengers move backward under the action of inertia, and the head and neck of the passengers contact the headrest on the seat. At present, the car seat includes a seat body and a headrest, and the headrest is usually fixedly connected with the seat. Since the headrest is usually fixedly connected with the seat, the headrest cannot move relative to the seat, which makes the impact force on the head and neck of the passengers when they contact the headrest larger in the above two scenarios, and the passengers may be unconscious and unable to perform self-rescue, which poses a safety hazard.

[0049] The embodiments of the present disclosure provide a car seat protection system, as shown in Figure 1 The car seat includes a seat assembly 1, a headrest assembly 2, and a controller 3.

[0050] The seat assembly 1 is slidably connected with the automobile cockpit base 100 in the vehicle length direction. The headrest assembly 2 comprises a driving member 21, a headrest 22 and a pressure sensor 23. The fixed part 211 of the driving member 21 is connected with the seat assembly 1. The headrest 22 is located in the first direction of the driving member 21. The pressure sensor 23 is located between the movable part 212 of the driving member 21 and the headrest 22, and is connected with the movable part 212 and the headrest 22 respectively. The controller 3 is electrically connected with the automobile accelerometer, the driving member 21 and the pressure sensor 23 respectively, and is configured to: acquire an acceleration value detected by the automobile accelerometer, acquire a pressure value detected by the pressure sensor 23, and control the movable part 212 to move in the second direction in the case that the acceleration value is greater than an acceleration threshold value and the pressure value is greater than a pressure threshold value. The first direction is a direction in which the tail of the vehicle points to the head of the vehicle, and the second direction is a reverse direction of the first direction.

[0051] In this way, in the case that the automobile collides or is rear-ended during driving, the controller 3 can detect that the acceleration of the automobile is greater than the acceleration threshold value. When the head and neck of the passenger contact the headrest assembly 2, the controller 3 can detect, through the pressure sensor 23, that the pressure value borne by the headrest 22 is greater than the pressure threshold value. At this time, the controller 3 controls the movable part 212 of the driving member 21 to move in the second direction (i.e., a direction in which the head of the vehicle points to the tail of the vehicle). The headrest 22 moves synchronously with the movable part 212, so that the contact time of the headrest 22 with the head and neck position of the passenger increases, and thus the support force borne by the head and neck position of the passenger from the headrest 22 decreases. When the pressure sensor 23 detects that the pressure value borne by the headrest 22 is less than or equal to the pressure threshold value, the movable part 212 stops moving. At this time, the support force borne by the head and neck position is relatively small, and thus the impact force borne by the head and neck of the passenger when contacting the headrest can be reduced, thereby improving the safety performance of the automobile seat protection system.

[0052] It can be understood that the actual values of the pressure threshold value and the acceleration threshold value can be set by the technician according to actual needs, and the embodiments of the present disclosure do not limit the same.

[0053] In a possible embodiment, the headrest assembly 2 comprises a plurality of driving members 21 and a plurality of pressure sensors 23.

[0054] Referring to Figure 2 , the headrest assembly 2 comprises a plurality of driving members 21 and a plurality of pressure sensors 23. The fixed part 211 of each driving member 21 is connected with the seat assembly 1. The movable part 212 is located in the first direction of the fixed part 211 and is slidably connected with the fixed part 211. The projections of the plurality of movable parts 212 in the vehicle length direction are located on the headrest 22. Each pressure sensor 23 is located in the first direction of one movable part 212 and is connected with the movable part 212. The controller 3 is electrically connected with the plurality of driving members 21 and the plurality of pressure sensors 23 respectively.

[0055] In the implementation, the controller 3 can receive the pressure values detected by the plurality of pressure sensors 23 respectively. In the case that the vehicle is in a collision or a rear-end collision during driving, the controller 3 can detect that the acceleration of the vehicle is greater than an acceleration threshold. When the pressure value detected by any one of the pressure sensors 23 is greater than a pressure threshold, the controller 3 controls the movable part 212 of the driving member 21 corresponding to the pressure sensor 23 to move to the second direction.

[0056] In this way, the fitting degree of the headrest 22 and the head and neck of the passenger can be improved.

[0057] In an example, the plurality of driving members 21 are distributed in a matrix manner.

[0058] Referring to Figure 3 The driving member 21 further comprises a connecting seat 213, and the plurality of fixed parts 211 are connected to the connecting seat 213 and distributed in a matrix manner. Correspondingly, each movable part 212 is located on a side of a fixed part 211 away from the connecting seat 213 and is in transmission connection with the fixed part 211.

[0059] Exemplarily, the plurality of driving members 21 are distributed in a 4x2 matrix manner, so that the fitting degree between the plurality of driving members 21 and the headrest 22 can be improved.

[0060] In an example, the driving member 21 is a linear motor, the fixed part 211 is a stator of the linear motor, and the movable part 212 is a rotor of the linear motor. The stator has an accommodation space, and the rotor is at least partially located in the accommodation space and in sliding connection with the stator. The connection between the stator and the seat assembly 1 can be clamping or threaded connection, which is not limited in the embodiments of the present disclosure.

[0061] In the implementation, when the rotor moves to the inside of the accommodation space, the movable part 212 moves to the second direction, and when the rotor moves away from the accommodation space, the movable part 212 moves to the first direction.

[0062] In an example, the driving member 21 comprises a motor and a screw rod, the axial direction of the screw rod is parallel to the vehicle length direction, and the outer wall of the output shaft of the motor is provided with external threads. The output shaft is in transmission connection with the screw rod through the external threads. The motor is the fixed part 211 of the driving member 21, and the screw rod is the movable part 212 of the driving member 21.

[0063] In the implementation, when the output shaft of the motor rotates around a first circumferential direction, the screw rod as a whole moves to the first direction, and when the output shaft of the motor rotates around a second circumferential direction, the screw rod as a whole moves to the second direction.

[0064] In an example, the controller 3 acquires the pressure value detected by the pressure sensor 23, and controls the moving of the movable part 212 to the second direction according to the speed matched with the pressure value.

[0065] In implementation, the controller 3 can pre-establish the corresponding relationship between the numerical range of the pressure value and the speed, and store it. The greater the value corresponding to the numerical range of the pressure value is, the greater the specific value of the speed is. For example, the corresponding relationship between the numerical range of the pressure value and the speed is shown in Table 1, which is only an example, and the related technical personnel can set it by themselves in actual implementation.

[0066] Table 1

[0067] Pressure value (N) Speed (m / s) 80-90 0.6 90-100 0.7 100-110 0.8 110-120 0.9 120-130 1.0 130-140 1.1

[0068] For example, the controller 3 acquires the pressure value detected by the pressure sensor 23 as 85N, the numerical range to which the pressure value belongs is 80N-90N, and the speed corresponding to the numerical range is 0.6m / s. Accordingly, the controller 3 determines 0.6m / s as the target speed, and controls the movable part 212 to move to the second direction at the target speed.

[0069] In this way, when the head and neck of the passenger contacts the headrest 22 with different impact forces, the movable part 212 of the driving part 21 can move to the second direction at a speed matched with the impact force, so as to reduce the support force of the headrest 22 on the head and neck position, and improve the safety performance.

[0070] In some possible embodiments, the seat assembly 1 is slidingly connected with the automobile cabin base 100 in the vehicle length direction. Referring to Figure 1 , the seat assembly 1 comprises a linear motor 11 and a seat 12. The stator 111 of the linear motor 11 is connected with the automobile cabin base 100, the slide rail of the stator 111 extends in the vehicle length direction, the slide block 112 of the linear motor 11 is slidingly connected with the slide rail, and the seat 12 is connected with the slide block 112.

[0071] In an example, the connection between the stator 111 and the automobile cabin base 100 is welding or clamping, and the connection between the seat 12 and the slide block 112 is welding or clamping.

[0072] The connection between the stator 111 and the automobile cabin base 100 and the connection between the seat 12 and the slide block 112 can be the same or different, for example, both are clamping connection, and the embodiments of the present disclosure do not limit this.

[0073] In an example, the linear motor 11 is electrically connected with the controller 3, and the controller 3 is configured to control the moving of the movable part 212 to the second direction according to the size of the pressure value, or control the moving of the movable part 212 and the slide block 112 to the second direction respectively.

[0074] Specifically, the controller 3 is configured to acquire an acceleration value detected by an acceleration sensor of the vehicle, acquire a pressure value detected by the pressure sensor 23, in a case where the acceleration value is greater than an acceleration threshold value, determine sizes of the pressure value and a first pressure threshold value and a second pressure threshold value respectively, in a case where the pressure value is greater than the first pressure threshold value and less than the second pressure threshold value, control the movable part 212 to move in the second direction at a first speed, and in a case where the pressure value is greater than or equal to the second pressure threshold value, control the movable part 212 and the slider 112 to move in the second direction at a second speed.

[0075] The second pressure threshold value is greater than the first pressure threshold value, and the second speed is less than the first speed.

[0076] Exemplarily, the first pressure threshold value can be 80 N, the second pressure threshold value can be 100 N, the first speed can be 0.6 m / s, and the second speed can be 0.4 m / s.

[0077] In this way, the excessive displacement of the headrest 22 in the second direction relative to the seat 12 caused by the movement of the movable part 212 alone can be avoided, and thus the excessive backward tilting angle of the head and neck of the occupant can be avoided, and the safety performance is improved.

[0078] In an example, the controller 3 is configured to control the movable part 212 to move in the second direction at a third speed and control the slider 112 to move in the second direction at a fourth speed based on a ratio of a current relative displacement between the movable part 212 and the fixed part 211 to a maximum relative displacement.

[0079] The ratio between the third speed and the fourth speed is a first ratio, the difference between the maximum relative displacement and the current relative displacement is a remaining relative displacement, the ratio between the current relative displacement and the remaining relative displacement is a second ratio, and the first ratio is equal to the second ratio.

[0080] In implementation, the controller 3 acquires the pressure value detected by the pressure sensor 23, determines a target speed according to a corresponding relationship between a numerical range to which the pressure value belongs and a speed, and the target speed is the sum of the third speed and the fourth speed. In addition, the controller 3 is electrically connected with the movable part 212, the user acquires the current relative displacement between the movable part 212 and the fixed part 211, and the controller 3 pre-stores the maximum relative displacement between the movable part 212 and the fixed part 211. In implementation, the controller determines the remaining relative displacement between the movable part 212 and the fixed part 211 according to the current relative displacement and the maximum relative displacement, allocates the target speed such that the ratio between the third speed and the fourth speed is equal to the ratio between the current relative displacement and the remaining relative displacement, controls the movable part 212 to move in the second direction at the third speed, and controls the slider 112 to move in the second direction at the fourth speed.

[0081] In this way, the excessive displacement of the headrest 22 relative to the seat 12 in the second direction caused by the movement of the movable part 212 alone can be avoided, and the excessive backward angle of the head and neck of the occupant can be avoided, and the safety performance is improved.

[0082] In an example, the controller 3 acquires the pressure value detected by the pressure sensor 23, and determines the target speed corresponding to the target numerical range to which the pressure value belongs in the pre-stored corresponding relationship between the numerical range of the pressure value and the speed. Subsequently, the controller 3 acquires the current relative displacement of the movable part 212 relative to the fixed part 211, respectively determines the size of the current relative displacement and the first displacement threshold value and the second displacement threshold value, and controls the movable part 212 to move in the second direction at the target speed in the case that the current relative displacement is less than the first displacement threshold value. In the case that the current relative displacement is greater than or equal to the first displacement threshold value and less than the second displacement threshold value, the movable part 212 is controlled to move in the second direction at the third speed, and the control slider 112 is controlled to move in the second direction at the fourth speed. In the case that the current relative displacement is greater than the second displacement threshold value, the control slider 112 is controlled to move in the second direction at the target speed.

[0083] The second displacement threshold value is greater than the first displacement threshold value. The specific determination process of the third speed and the fourth speed can be referred to the foregoing description, which will not be described herein again.

[0084] In this way, the excessive displacement of the headrest 22 relative to the seat 12 in the second direction caused by the movement of the movable part 212 alone can be avoided, and the excessive backward angle of the head and neck of the occupant can be avoided, and the safety performance is improved.

[0085] In some possible embodiments, the controller 3 adjusts the height of the headrest assembly 2 according to the identity of the occupant.

[0086] Referring to Figure 4 The headrest assembly 2 and the seat assembly 1 are slidably connected in the vehicle height direction, and the automobile seat protection system further includes a camera assembly 4 configured to capture a face image of the occupant on the seat assembly 1 and send the face image to the controller 3. The controller 3 is further configured to: based on a corresponding relationship between the face image and a pre-stored target face image, control the headrest assembly 2 to move to a preset position in the vehicle height direction.

[0087] In an example, the headrest assembly 2 is drivingly connected to the seat assembly 1 through a linear motor. The stator of the linear motor can be connected to the seat assembly 1, and the end of the rotor is connected to the fixed part 211 in the headrest assembly 2. Alternatively, the stator of the linear motor can be connected to the fixed part 211 in the headrest assembly 2, and the stator can be connected to the seat assembly 1. The above connection modes can be welding, bonding or threaded connection, and the embodiments of the present disclosure do not limit the connection modes.

[0088] In implementation, the controller 3 can pre-store a plurality of face images, each of which is provided with a corresponding headrest assembly parameter, which can include the height of the headrest assembly, the initial position of the movable part 212 of each drive 21 in the headrest assembly, and the like. After the camera assembly 4 captures the face image of the vehicle occupant, the face image is sent to the controller 3, which can determine the target face image matching the face image captured by the camera assembly 4 from the plurality of pre-stored face images through feature analysis, and determine the target headrest assembly parameter corresponding to the target face image as the target headrest assembly parameter, and adjust the height of the headrest assembly 2 and the shape of the headrest assembly 2 according to the headrest assembly parameter.

[0089] In this way, the fitting degree between the headrest assembly 2 and the vehicle occupant can be improved, and the user experience can be improved.

[0090] In some possible implementations, the headrest 22 includes an energy-absorbing part 221, a filling part 222, and a woven mesh cover 223.

[0091] Referring to Figure 5 , the energy-absorbing part 221 has a block structure, the woven mesh cover 223 is sleeved on the outside of the energy-absorbing part 221, and the filling part 222 is located between the woven mesh cover 223 and the energy-absorbing part 221.

[0092] In an example, the shape of the energy-absorbing part 221 can be adapted to the head and neck of the vehicle occupant, and the energy-absorbing part 221 can be made of a high-energy-absorbing material such as ABS engineering material, so that the fitting degree between the headrest 22 and the head and neck of the vehicle occupant can be improved, and the support reliability of the headrest 22 to the head and neck of the vehicle occupant can be improved.

[0093] Exemplarily, the material of the energy-absorbing part 221 can also be a polymer foam, a controllable deformation metal, or a composite material.

[0094] In implementation, the size and shape of the headrest 22 can be adjusted through ergonomic principles, safety requirement analysis, and numerical simulation simulation, so that the corresponding parameters of the headrest 22 are determined through calculation simulation, to ensure that the headrest 22 can provide sufficient support and protection effect to the head and neck of the vehicle occupant.

[0095] Exemplarily, the energy-absorbing part 221 can be processed and formed by an injection molding process.

[0096] In an example, the energy-absorbing part 221 includes a shell and an energy-absorbing body part, and in implementation, the shell can be formed by casting process through a mold, and the energy-absorbing body part can be processed and formed in the shell by injection molding process. In this way, the production process can be simplified, which is helpful to reduce the manufacturing cost of the automobile seat protection system and improve the manufacturing efficiency of the automobile seat protection system.

[0097] The technical scheme provided by the embodiment of the present disclosure at least has the following beneficial effects:

[0098] The embodiment of the present disclosure provides a car seat protection system, wherein a seat assembly 1 is slidably connected with a car cockpit base 100 in a length direction of the car. A headrest assembly 2 comprises a driving member 21, a headrest 22 and a pressure sensor 23. The fixed part 211 of the driving member 21 is connected with the seat assembly 1. The headrest 22 is located in the first direction of the driving member 21. The pressure sensor 23 is located between the movable part 212 of the driving member 21 and the headrest 22, and the two ends are connected with the movable part 212 and the headrest 22 respectively. A controller 3 is electrically connected with the car accelerometer, the driving member 21 and the pressure sensor 23, for obtaining the acceleration value detected by the car accelerometer, obtaining the pressure value detected by the pressure sensor 23, and controlling the movable part 212 to move to the second direction in the case that the acceleration value is greater than the acceleration threshold value and the pressure value is greater than the pressure threshold value. The first direction is the direction of the tail pointing to the head, and the second direction is the reverse direction of the first direction. In this way, in the case that the car collides or is rear-ended during driving, the controller 3 can detect that the acceleration of the car is greater than the acceleration threshold value. When the head and neck of the passenger contact the headrest assembly 2, the controller 3 can detect that the pressure value borne by the headrest 22 is greater than the pressure threshold value through the pressure sensor 23. At this time, the controller 3 controls the movable part 212 of the driving member 21 to move to the second direction (i.e. the direction of the head pointing to the tail), and the headrest 22 moves synchronously with the movable part 212, so that the contact time of the headrest 22 with the head and neck position of the passenger is increased, and thus the supporting force of the headrest 22 on the head and neck position of the passenger is reduced. When the pressure sensor 23 detects that the pressure value borne by the headrest 22 is less than or equal to the pressure threshold value, the movable part 212 stops moving. At this time, the supporting force on the head and neck position is relatively small, so that the impact force on the head and neck of the passenger when contacting the headrest can be reduced, thereby improving the safety performance of the car seat protection system.
