[0075] Wherein, the two front connecting brackets 7 are connected to the leg support assembly 3, and the two rear connecting brackets 6 are connected to the backrest assembly 2;

[0076] The two front connecting brackets 7 are used to drive the leg support assembly 3 to lift up when the front end of the seat basin is lifted;

[0077] The two rear connecting brackets 6 are used to adjust the angle of the rear end of the seat basin when the front end of the seat basin is lifted, so as to achieve a zero-gravity state for the leg support assembly 3 and the backrest assembly 2.

[0078] In this exemplary embodiment, the bracket assembly includes: a seat basin; and two front connecting brackets 7, which are hinged to the front side of the seat basin bottom; and two rear connecting brackets 6, which are hinged to the rear side of the seat basin bottom;

[0079] At the same time, the two front connecting brackets 7 are connected to the leg rest assembly 3, and the two rear connecting brackets 6 are connected to the backrest assembly 2; the two front connecting brackets 7 can drive the leg rest assembly 3 to be lifted when the front end of the seat basin is lifted; during the process of lifting the front end of the seat basin, the two rear connecting brackets 6 can cooperate with the rear end of the seat basin to adjust the angle, so as to facilitate adjusting the leg rest assembly 3 and the backrest assembly 2 to a zero gravity state.

[0080] In some embodiments, the adjustment mechanism comprises:

[0081] Two lifting arms 8 are hinged to the free ends of the two front connecting brackets 7 in a one-to-one correspondence;

[0082] a zero-gravity stabilizing rod 9 connected between the two lifting arms 8 and used to achieve synchronous movement of the two lifting arms 8;

[0083] A motor bracket 10 connected to the zero-gravity stabilizing rod 9;

[0084] A lead screw motor 11, connected to the motor bracket 10;

[0085] Wherein, the motor bracket 10, the two lifting arms 8 and the zero-gravity stabilizing rod 9 are welded into one body;

[0086] The screw motor 11 pushes the motor bracket 10 through the extension and retraction of the screw; and the motor bracket 10 pushes the two lifting arms 8 to lift through the zero-gravity stabilization rod 9; the two lifting arms 8 push the two front connecting brackets 7 to drive the front end of the basin to lift.

A zero-gravity stabilizing rod 9 is provided between the two lifting arms 8, and the zero-gravity stabilizing rod 9 is connected between the two lifting arms 8, so that the two lifting arms 8 can move synchronously.

[0088] In this exemplary embodiment, the motor bracket 10, the two lifting arms 8 and the zero gravity stabilizing rod 9 are welded into one. The lead screw motor 11 can push the motor bracket 10 to move through the extension of the lead screw, and the motor bracket 10 pushes the two lifting arms 8 to lift through the zero gravity stabilizing rod 9, and then the two lifting arms 8 push the two front connecting brackets 7 to drive the front end of the seat basin to lift, so that the seat basin state can be adjusted by the lead screw motor 11.

[0089] In the present application, when the seat is in a zero-gravity state, when the vehicle brakes suddenly, collides, or turns sharply, the motor of the leg rest part is quickly powered off and reset, so that the leg rest returns to its original position first, and then when the brake decelerates suddenly, collides, or accelerates sharply, or rolls, the oil can be quickly released or the power is quickly turned off and reset by controlling the hydraulic or screw motor. In the present application, in order to accelerate the return, the return spring can be released to quickly return it to its normal position. At the same time, depending on the severity of the situation, the side airbags on both sides of the seat pop up quickly to wrap the body, and the knee airbags under the front seat also pop up to quickly protect the passenger's body. At the same time, the pre-tightened seat belt reacts quickly and directly tightens the seat belt to prevent the passenger from flying out. Among them, the screw motor 11 can be replaced by a hydraulic lifter to control the zero-gravity stabilizer bar through hydraulic control, so that the hydraulic lifter drives the zero-gravity stabilizer bar 9 to move, and then realizes that the two lifting arms 8 push the two front connecting brackets 7 to drive the front end of the seat basin to lift, so that the seat basin state can be adjusted by the hydraulic lifter 11.

[0090] In some embodiments, the bottoms of the two rear connecting brackets 6 are symmetrically hinged at the rear position of the slide rail device;

The two front connecting brackets 7 are hinged with the two lifting arms 8 in a one-to-one correspondence, so that the motor bracket 10 drives the zero-gravity stabilization rod 9 to move, and then the two front connecting brackets 7 are pushed by the two lifting arms 8 to drive the front end of the seat basin to lift, so that the seat basin state can be adjusted by the lead screw motor 11. Among them, the seat body 1 also includes a seat base 15 and a connection structure 16 between the seat bases 15.

[0094] In some embodiments, the spring device includes a limit module;

[0095] The limiting module is located in the spring device; the limiting module is used to limit the elastic structure in the spring device; wherein,

[0096] When a vehicle collides and the seat body is displaced to a predetermined position on the slide rail device, the limit module is triggered to move, so that the elastic structure in the spring device pops out to reset the seat body.

[0097] In this exemplary embodiment, in order to facilitate the control of the spring device, when the vehicle does not collide, the elastic structure in the spring device can be limited by the limiting module, so that the elastic structure in the spring device does not pop out and does not generate elastic force on the seat body. When the vehicle collides, the limiting module is activated and no longer limits the elastic structure in the spring device, so that the elastic structure generates elastic force on the seat body, thereby resetting the seat body.

[0098] In some embodiments, Figure 7 FIG. 1 is a schematic diagram of a spring device structure in a vehicle collision protection seat according to an exemplary embodiment. Figure 7 As shown, the limit module includes an eccentric rotating piece 65 and a driving motor 64; wherein,

[0099] When the vehicle collides and the seat body is offset to the position of the limit module on the slide rail device, the drive motor 64 is triggered to rotate, driving the eccentric rotating piece 65 to move, so that the elastic structure 62 in the spring device pops out to reset the seat body.

[0100] In this exemplary embodiment, the eccentric rotating piece 65 directly acts on the elastic structure 62 of the spring device 5, and can limit the elastic structure 62 in the spring device 5, so that the elastic structure 62 in the spring device 5 does not pop out and does not generate elastic force on the seat body 1. When the vehicle collides, the eccentric rotating piece 65 moves and no longer limits the elastic structure 62 in the spring device 5, so that the elastic structure 62 generates elastic force on the seat body 1, thereby resetting the seat body 1.

[0101] In the present exemplary embodiment, the spring device 5 comprises an upper contact portion 60 and a lower contact portion 61;

[0102] A telescopic structure 63 is provided between the upper contact portion 60 and the lower contact portion 61;

[0103] The telescopic structure 63 has the elastic structure 62 therein;

[0104] The eccentric rotating piece 65 of the limiting module can compress the elastic structure 62 . When the driving motor 64 rotates, the eccentric rotating piece 65 rotates, so that the eccentric rotating piece 65 is separated from the elastic structure 62 and loses the compression effect on the elastic structure 62 .

[0105] In some embodiments, a pressure sensor is provided at the predetermined position; the pressure sensor is connected to the controller of the drive motor 64; after receiving the electrical signal from the pressure sensor, the controller of the drive motor 64 controls the drive motor 64 to rotate.

[0106] In this exemplary embodiment, in order to facilitate the control of the elastic force of the spring device on the seat and to reset the seat, a pressure sensor may be provided at a predetermined position in the present application. The seat displacement is detected by the pressure sensor. When the pressure sensor detects the seat displacement, the pressure sensor may automatically send a trigger signal to the controller of the drive motor 64 to trigger the drive motor 64 to rotate, thereby driving the eccentric rotating piece 65 installed on the rotating shaft of the drive motor 64 to rotate, so that the eccentric rotating piece 65 is freed from the pressing effect on the elastic structure 62, thereby releasing the elastic structure 62 of the spring device.

[0107] In this exemplary embodiment, the drive motor 64 can also be directly controlled by the vehicle control system. When the seat is offset to a predetermined position, the pressure sensor can send a trigger signal to the vehicle control system, and the vehicle control system controls the drive motor 64 to rotate, so that the drive motor 64 drives the eccentric rotating plate 65 to rotate, thereby making the eccentric rotating plate 65 break away from the pressing effect on the elastic structure 62, and then release the elastic structure 62 of the spring device.

[0108] According to the vehicle collision protection system of the embodiment of the present disclosure, it includes: a vehicle collision protection seat, including a seat body, a slide rail device and a spring device; the seat body is located on the slide rail device; the spring device is located under the seat body and is fixedly connected to the seat body; a vehicle collision sensing module is used to detect the vehicle collision state sensed when the vehicle collides; a seat reset control unit is used to control the trigger state of the spring device of the vehicle collision protection seat according to the vehicle collision state, so that when the vehicle collides, the spring device triggers to reset the seat body; wherein the vehicle collision state includes the vehicle external collision state and the vehicle internal collision state. In the present application, when protecting the passengers in the vehicle, a seat body that can slide on the slide rail is used, and a spring device is installed under the seat body. When the vehicle collides, the seat reset control unit can control the trigger state of the spring device of the vehicle collision protection seat according to the vehicle collision state, so that when the vehicle collides, the spring device triggers to reset the seat body to buffer the inertia caused by the vehicle collision, thereby playing a role in protecting the passengers by buffering the inertia and resetting the seat.

[0109] In some embodiments, including:

[0110] The airbag and seatbelt control unit is used to control the deployment state of the airbag and the pre-tensioning state of the seatbelt according to the vehicle collision state.

[0111] In this exemplary embodiment, when a collision occurs in a vehicle and a passenger needs to be protected, the deployment state of the airbag and the pre-tensioning state of the seat belt can be controlled according to the collision state of the vehicle. For example, the collision state of the vehicle is divided into collision levels. Therefore, the deployment state of the airbag can be controlled according to the collision level corresponding to the collision of the vehicle. For example, according to the severity of the collision of the vehicle, the collision level of the vehicle can be divided into three levels from severe to general, including severe, relatively severe, and general. For example, severe can be defined as the collision causing serious harm to the passenger, relatively severe can be defined as causing some harm to the passenger, and generally can be defined as not causing harm to the passenger. At this time, if the vehicle has a severe collision, the airbag and seat belt control unit can be triggered to release the airbag and pre-tighten the seat belt, thereby improving the safety protection of the passenger. If the vehicle has a general collision, the airbag and seat belt control unit may not be triggered. By comparing and distinguishing the collision degree, it is beneficial to improve the safety protection of the passenger while avoiding the waste of airbag resources.

[0112] In some embodiments, the vehicle collision sensing module at least includes:

[0113] A vehicle collision state sensing module is used to sense the external collision state of the vehicle when the vehicle collides;

[0114] The vehicle internal status confirmation module is used to obtain the vehicle internal collision status through the in-vehicle camera, various seat sensors and seat belt sensors.

[0115] In this exemplary embodiment, when determining the collision situation when the vehicle collides, the vehicle collision state sensing module can sense the vehicle's external collision state when the vehicle collides; the vehicle internal state confirmation module calls the in-vehicle camera, each seat sensor and seat belt sensor to obtain the vehicle's internal collision state. In this way, when the vehicle collides, the vehicle's external collision state and the vehicle's internal collision state can be obtained, which is conducive to taking safety protection measures for passengers, thereby improving the safety protection of passengers when the vehicle collides.

[0116] In some embodiments, the vehicle collision state sensing module includes:

[0117] Wheel speed sensors, used to measure vehicle wheel speed, wheel angle and wheel rolling direction;

[0118] Deceleration sensor, used to measure vehicle acceleration, deceleration and vehicle vibration;

[0119] Tire pressure sensor, used to monitor tire pressure in real time;

[0120] Body displacement sensors, used to monitor changes in the position of the vehicle body relative to the axle or the ground;

[0121] Angle sensor, used to detect the rotation angle of the vehicle body;

[0136] The present disclosure provides a vehicle collision protection method, which is applied to a vehicle collision protection system, wherein the vehicle collision protection system includes a vehicle collision protection seat, a vehicle collision sensing module and a seat reset control unit; wherein the vehicle collision protection seat includes a seat body, a slide rail device and a spring device; the seat body is located on the slide rail device; the spring device is located under the seat body and is fixedly connected to the seat body.

[0137] Step 90, detecting the vehicle collision state sensed when the vehicle collides by the vehicle collision sensing module;

[0138] Step 91, controlling the triggering state of the spring device of the vehicle collision protection seat according to the vehicle collision state through the seat reset control unit, so that when the vehicle collides, the spring device is triggered to reset the seat body; wherein the vehicle collision state includes the vehicle external collision state and the vehicle internal collision state.

[0139] In this exemplary embodiment, the vehicle collision protection seat includes a seat body, a slide rail device and a spring device; the seat body is located on the slide rail device; the spring device is located under the seat body and is fixedly connected to the seat body; a vehicle collision sensing module is used to detect the vehicle collision state sensed when the vehicle collides; and a seat reset control unit is used to control the trigger state of the spring device of the vehicle collision protection seat according to the vehicle collision state, so that when the vehicle collides, the spring device triggers to reset the seat body; wherein the vehicle collision state includes the vehicle external collision state and the vehicle internal collision state. In the present application, when protecting the passengers in the vehicle, a seat body that can slide on the slide rail is used, and a spring device is installed under the seat body. When the vehicle collides, the seat reset control unit can control the trigger state of the spring device of the vehicle collision protection seat according to the vehicle collision state, so that when the vehicle collides, the spring device triggers to reset the seat body to buffer the inertia caused by the vehicle collision, thereby protecting the passengers by buffering the inertia and resetting the seat.

[0140] In some embodiments, including:

[0142] In this exemplary embodiment, when a collision occurs in a vehicle and a passenger needs to be protected, the deployment state of the airbag and the pre-tensioning state of the seat belt can be controlled according to the collision state of the vehicle. For example, the collision state of the vehicle is divided into collision levels. Therefore, the deployment state of the airbag can be controlled according to the collision level corresponding to the collision of the vehicle. For example, according to the severity of the collision of the vehicle, the collision level of the vehicle can be divided into three levels from severe to general, including severe, relatively severe, and general. For example, severe can be defined as the collision causing serious harm to the passenger, relatively severe can be defined as causing some harm to the passenger, and generally can be defined as not causing harm to the passenger. At this time, if the vehicle has a severe collision, the airbag and seat belt control unit can be triggered to release the airbag and pre-tighten the seat belt, thereby improving the safety protection of the passenger. If the vehicle has a general collision, the airbag and seat belt control unit may not be triggered. By comparing and distinguishing the collision degree, it is beneficial to improve the safety protection of the passenger while avoiding the waste of airbag resources.

[0156] In some embodiments, sensing the external collision state of the vehicle when the vehicle collides by means of a vehicle collision state sensing module includes:

[0157] Through the vehicle external sensing and data providing module, the camera and radar on the vehicle side are called to obtain the distance between the external vehicle and the vehicle, and according to the change of the distance between the external vehicle and the vehicle and the driving status information of the vehicle sensed by the vehicle collision status sensing module, the relative speed between the vehicle and the external vehicle and the absolute speed of the external vehicle are evaluated, and the analysis data corresponding to the relative speed between the vehicle and the external vehicle and the absolute speed of the external vehicle are provided to the passenger passive protection evaluation module; wherein, the driving status information of the vehicle includes the vehicle wheel speed, wheel angle, wheel rolling direction, vehicle acceleration, deceleration, vehicle vibration, tire pressure, position change of the vehicle body relative to the axle or the ground, rotation angle of the vehicle body, vehicle bearing, motor and engine output torque;

[0162] In this exemplary embodiment,

[0163] In terms of the specific implementation of passenger safety protection, it can be carried out in the following ways:

[0164] When the passengers in the car are in a normal sitting position and are wearing seat belts, the airbags will be deployed and the seat belts will be pre-tensioned in time according to the intensity, location and direction of the collision in normal mode. At the same time, the vehicle body will do its utmost to resist the collision, such as releasing the brakes and retreating to reduce the collision, or actively steering to face the collision sideways to reduce the high-intensity damage of a head-on collision, or accelerating or decelerating to disengage in time when a large truck collides and overturns, and deploying all airbags to resist the truck's overturning and crushing damage.

[0165] When passengers in the car are in a zero-gravity state, the leg rest can be quickly returned to its position by releasing the motor control. At the same time, the hydraulic rod of the zero-gravity seat is relaxed, and a motor lifting device is installed at the rear of the zero-gravity seat to return the zero-gravity seat. At the same time, the seat air curtains on both sides of the seat open quickly to wrap the passengers, and the air curtain in front of the leg rest opens to prevent leg injuries.

[0166] When the rear passengers are watching the pad without wearing their seat belts, the front seat head airbags and the front seat rear lower airbags will pop out quickly to prevent the rear passengers from hitting the pad and flying out of the car.

[0167] The vehicle integrated system balance module balances the internal and external conditions of the vehicle. Through external and internal evaluations, it evaluates the possibility of external collision intrusion, intrusion depth and degree of damage, and internally evaluates the possibility of damage to vehicle personnel and the worst and optimal states. Then, through calculation and comprehensive processing, it directs steering, acceleration, braking, seat belts, and airbags to execute the optimal survival strategy for passengers and the vehicle body, and transfers its execution parameters to the vehicle passive protection execution module. Control various parameters.

[0168] Finally, the vehicle integrated system balance module, after receiving the evaluation results of the vehicle passive protection evaluation module, determines the optimal control strategy from the perspective of the entire vehicle based on the comprehensive results of the vehicle external sensing and data provision module, the vehicle front and rear side collision sensing module, and the vehicle brake sensing module, changes the driving state of the car, activates systems such as ESP at the same time by accelerating or decelerating or turning, changes the riding status of the passengers in the car, and makes the most effective and safe execution actions in a timely manner to ensure that the people in the car achieve the most optimized protection possibility.

[0169] In one case, the front auxiliary driver's seat is in a zero-gravity state, and the control execution operation of the rear vehicle in a normal seat state quickly lowers the zero-gravity state, and simultaneously starts operations such as seat belt pretensioning and airbag ejection.

[0170] In one situation, the front auxiliary driver's seat is in a zero-gravity state, and the person sitting in the rear seat is watching the display screen of the front seat without wearing a seat belt. In this situation, the front seat can be quickly folded down and the side airbags of the rear seats will wrap up the occupants of the rear car. At the same time, the rear airbags of the front car will pop out from the bottom to secure the legs of the occupants of the rear car to prevent them from flying forward.

[0171] In one case, the rear seats are in the zero-gravity position, the front seats are folded down or not folded down, and the rear seat passengers are not wearing seat belts. At this time, the leg rest is quickly folded down, the motor is powered off, and the leg rest quickly returns to its original position. At the same time, the rear auxiliary zero-gravity hydraulic rod quickly unloads force and returns to its original position. At the same time, in order to speed up the return speed, a pop-up device is set at the rear position. For example, a spring device, when a collision occurs, the spring device quickly pops open to ensure that the seat returns to its original position.

[0172] Second, when the vehicle collides or decelerates suddenly, the vehicle passive protection assessment module simultaneously receives data from the vehicle's internal status confirmation module, receives acceleration and braking data provided by the vehicle's acceleration and braking sensing module, and receives data from the vehicle's external sensing and data provision module. It conducts a comprehensive analysis and assessment based on the information provided by the vehicle's front and rear side collision sensing modules and the vehicle's steering sensing module, and proposes at least three optimal solutions for rapidly changing the vehicle's internal status to protect the occupants.

[0173] Among them, three types of rapid changes in the vehicle status may include:

[0174] When the passengers in the car are in a normal sitting position and are wearing seat belts, the airbags will be deployed and the seat belts will be pre-tensioned in time according to the intensity, location and direction of the collision in normal mode. At the same time, the vehicle body will do its utmost to resist the collision, such as releasing the brakes and retreating to reduce the collision, or actively steering to face the collision sideways to reduce the high-intensity damage of a head-on collision, or accelerating or decelerating to disengage in time when a large truck collides and overturns, and deploying all airbags to resist the truck's overturning and crushing damage.

[0175] When a passenger in the car is in a zero-gravity seat, the motor control is quickly released to return the leg rest to its original position. At the same time, the hydraulic rod of the zero-gravity seat is relaxed, and a motor lifting device is installed at the rear of the zero-gravity seat to return the zero-gravity seat to its original position. At the same time, the seat air curtains on both sides of the seat open quickly to wrap the passengers, and the air curtain in front of the leg rest opens to prevent leg injuries.

[0176] When the rear passengers are watching the pad without wearing their seat belts, the front seat head airbags and the front seat rear lower airbags will pop out quickly to prevent the rear passengers from hitting the pad and flying out of the car.

[0177] Among them, the vehicle integrated system balance module can generate the most optimized survival strategy. For example, the vehicle integrated system balance module obtains the internal and external conditions of the vehicle, and conducts external and internal assessments to assess the possibility of external collision intrusion, intrusion depth and degree of damage, and internally assesses the possibility of damage to vehicle personnel and the worst and optimal states, and then through calculation and comprehensive processing, directs steering, acceleration, braking, seat belts, and airbags to execute the most optimized survival strategy for passengers and the vehicle body.

[0178] Finally, the vehicle integrated system balance module, after receiving the evaluation results of the vehicle passive protection evaluation module, determines the optimal control strategy based on the comprehensive results of the vehicle external sensing and data provision module, the vehicle front and rear side collision sensing module, etc., and finally from the perspective of the entire vehicle, changes the driving state of the car, activates systems such as ESP by accelerating or decelerating or turning, and changes the riding status of the passengers in the car, and makes the most effective and safe execution actions in time to ensure that the people in the car achieve the most optimized protection possibility.

[0179] Among them, when realizing the protection of people in the car, the following situations may be included:

[0180] In the first case, the front auxiliary driver's seat is in a zero-gravity state, and the control execution operation of the rear vehicle in a normal seat state quickly lowers the zero-gravity state, and simultaneously starts operations such as seat belt pretensioning and airbag ejection.

[0181] In the second situation, the front auxiliary driver's seat is in a zero-gravity state, and the rear seatholder is watching the display screen of the front seat without wearing a seat belt. In this case, the front seat needs to be folded down quickly so that the rear seat side airbags can wrap up the rear car occupants. At the same time, the rear airbags of the front car will pop out from the bottom to secure the legs of the rear car occupants to prevent them from flying forward.

[0182] In the third case, the rear seats are in the zero-gravity position, the front seats are folded down or not folded down, and the rear seat passengers are not wearing seat belts. At this time, the leg rest can be quickly folded down, the motor is powered off, and the leg rest quickly returns to its original position. At the same time, the rear auxiliary zero-gravity hydraulic rod quickly unloads force and returns to its original position. At the same time, in order to speed up the return speed, a pop-up device is set at the rear position. For example, a spring device, when a collision occurs, the spring device quickly pops open to ensure that the seat returns to its original position.
