[0093] The screw end of the lead screw motor 11 is hingedly connected to the rear position of the slide rail device;

[0094] The zero-gravity stabilizing rod 9 is rotationally connected to the middle position of the slide rail device.

[0095] In the present exemplary embodiment, as shown in the figure, the first end of the screw rod 12 of the screw motor 11 is hinged at the rear position of the slide rail device, the second end of the screw rod 12 of the screw motor 11 is fixed with the motor support 10, the screw motor 11 is fixed on the motor support 10, and the screw motor 11 can drive the motor support 10 to move by the extension and retraction of the screw rod 12.

[0096] In some embodiments, Figure 6 is a schematic view of a spring device structure in a vehicle collision protection seat according to an exemplary embodiment. As Figure 6 shown, the spring device comprises a limiting module;

[0097] The limiting module is located in the spring device; the limiting module is used for limiting the elastic structure in the spring device; wherein,

[0098] When the vehicle collides and the seat body deviates to a predetermined position on the slide rail device, the limiting module is triggered to move, so that the elastic structure in the spring device is ejected to reset the seat body.

[0099] In the present exemplary embodiment, in order to facilitate the control of the spring device 5, in the case where the vehicle does not collide, the elastic structure in the spring device 5 can be limited by the limiting module, so that the elastic structure in the spring device 5 does not eject and does not produce elastic force on the seat body 1. When the vehicle collides, the limiting module acts and no longer limits the elastic structure in the spring device 5, so that the elastic structure produces elastic force on the seat body 1, thereby resetting the seat body 1.

[0100] In some embodiments, the limiting module comprises an eccentric rotating piece 65 and a driving motor 64; wherein,

[0101] When the vehicle collides and the seat body deviates to the limiting module on the slide rail device, the driving motor 64 is triggered to rotate, driving the eccentric rotating piece 65 to move, so that the elastic structure 62 in the spring device is ejected to reset the seat body.

[0102] In the example embodiment, the eccentric rotating piece 65 directly acts on the elastic structure 62 of the spring device 5, and the elastic structure 62 in the spring device 5 is limited so as not to pop out and not to generate elastic force on the seat body 1. When the vehicle collides, the eccentric rotating piece 65 acts, and the elastic structure 62 in the spring device 5 is no longer limited, so as to generate elastic force on the seat body 1, thereby resetting the seat body 1.

[0103] In the example embodiment, the spring device 5 includes an upper contact part 60 and a lower contact part 61.

[0104] The upper contact part 60 and the lower contact part 61 have an extension structure 63 therebetween.

[0105] The elastic structure 62 is arranged in the extension structure 63.

[0106] 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 the compression of the elastic structure 62 is lost.

[0107] In some embodiments, a pressure sensor is arranged at the predetermined position; the pressure sensor is connected with the controller of the driving motor 64; after the controller of the driving motor 64 receives the electric signal of the pressure sensor, the driving motor 64 is controlled to rotate.

[0108] In the example embodiment, in order to control the elastic force of the spring device on the seat and reset the seat, a pressure sensor can be arranged at the predetermined position in the application. The seat offset is detected by the pressure sensor. When the seat offset is detected by the pressure sensor, the pressure sensor can automatically send a trigger signal to the controller of the driving motor 64 to trigger the driving motor 64 to rotate, thereby driving the eccentric rotating piece 65 installed on the rotating shaft of the driving motor 64 to rotate, so that the eccentric rotating piece 65 is separated from the compression of the elastic structure 62, and the elastic structure 62 of the spring device is released.

[0109] In the example embodiment, the driving motor 64 can also be directly controlled by the vehicle control system. When the seat is offset to the predetermined position, the pressure sensor can send a trigger signal to the vehicle control system, and the vehicle control system controls the driving motor 64 to rotate, thereby driving the eccentric rotating piece 65 to rotate, so that the eccentric rotating piece 65 is separated from the compression of the elastic structure 62, and the elastic structure 62 of the spring device is released.

[0110] In the present application, when the seat is in a zero-gravity state, when the vehicle suddenly brakes or collides or sharply turns, the leg support part motor quickly powers off and resets, allowing the leg support to return to its original position first. Then, when the brake suddenly decelerates, collides, or sharply turns accelerates, or rolls over, the hydraulic or lead screw motor can quickly release the oil or quickly power off and reset. In the present application, to speed up the return, the return spring can be released to quickly return to the normal position. At the same time, depending on the severity, the side airbags on both sides of the seat quickly pop out and wrap around the body, and the knee airbags under the front seat also pop out and quickly protect the passenger's body. At the same time, the pre-tightened safety belt quickly reacts and directly tightens the safety belt to prevent the passenger from flying out. Among them, the lead 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 the two lifting arms 8 push the two front connecting brackets 7 to lift the front end of the seat basin, so that the hydraulic lifter 11 can adjust the state of the seat basin.

[0111] The present disclosure provides a vehicle, comprising:

[0112] The vehicle collision protection seat described in each of the above embodiments;

[0113] The airbag is located inside the vehicle body;

[0114] The camera module is located outside the vehicle body;

[0115] The collision detection sensor is located inside the vehicle body;

[0116] The vehicle collision protection control system; the airbag, the camera module and the collision detection sensor are electrically connected with the vehicle collision protection control system;

[0117] The vehicle collision protection control system is used for acquiring vehicle collision images through the camera module and acquiring vehicle collision states through the collision detection sensor, and controlling the opening state of the airbag based on the vehicle collision state.

[0118] In the present exemplary embodiment, the vehicle collision protection seat can be installed in the vehicle cabin. At the same time, in order to improve the protection effect of the occupant, the vehicle can be installed with an airbag, a camera module and a collision detection sensor. Among them, the camera module can acquire vehicle collision images and the collision detection sensor can acquire vehicle collision states through the vehicle collision protection control system, and then the opening state of the airbag can be controlled based on the vehicle collision state. For example, through the detection data of the vehicle collision image and the collision detection sensor, it is determined that the vehicle has a serious collision accident or a serious sudden accident, and then the airbag can be controlled to open and the safety belt can be pre-tightened to protect the occupant.

[0119] In some embodiments, the collision detection sensor comprises at least one of the following sensors:

[0120] Wheel speed sensor, deceleration sensor, tire pressure sensor, vehicle body displacement sensor, rotation angle sensor, torque sensor, collision sensor.

[0121] In the present exemplary embodiment, the wheel speed sensor is used to measure the wheel speed, wheel angle, and wheel rolling direction of the vehicle. The deceleration sensor is used to measure the acceleration, deceleration, and vibration of the vehicle. The tire pressure sensor is used to monitor the tire pressure in real time. The vehicle body displacement sensor is used to monitor the position change of the vehicle body relative to the axle or the ground. The rotation angle sensor is used to detect the rotation angle of the vehicle body. The torque sensor is used to measure the torque output by the vehicle bearings, motors, engines, and other devices. The collision sensor is used to detect and measure the collision or impact between vehicles and convert this physical phenomenon into an electrical signal so that the device or system can respond accordingly. In addition to the above-mentioned sensors, other sensors that can be used for vehicle collision detection can also be deployed in the vehicle. This is only an example and is not limiting.

[0122] In the present exemplary embodiment, the vehicle collision protection control system comprehensively judges the severity of the vehicle collision accident or emergency accident based on the detection information of the above-mentioned sensors, and then controls the opening state of the airbag and the pretensioning state of the seatbelt according to the severity of the vehicle collision accident or emergency accident, thereby effectively improving the safety of the passengers.

[0123] The present disclosure provides a vehicle collision protection system. Figure 7 The vehicle collision protection system structure diagram shown in accordance with an exemplary embodiment. As Figure 7 shown, the vehicle collision protection system comprises:

[0124] The vehicle collision protection seat 01 comprises a seat body, a slide rail device, and a spring device. The seat body is located on the slide rail device, and the spring device is located below the seat body and is fixedly connected to the seat body.

[0125] The vehicle collision sensing module 02 is used to detect the vehicle collision state sensed when the vehicle collides.

[0126] The seat reset control unit 03 is used to control the triggering state of the spring device of the vehicle collision protection seat according to the vehicle collision state, so that the spring device triggers the reset of the seat body when the vehicle collides. The vehicle collision state includes the external collision state of the vehicle and the internal collision state of the vehicle.

[0127] In some embodiments, it comprises:

[0128] An airbag and seatbelt control unit is used to control the opening state of the airbag and the pre-tightening state of the seatbelt according to the vehicle collision state.

[0129] In the example embodiment, when the vehicle is in a collision state requiring protection of the occupant, the opening state of the airbag and the pre-tightening state of the seatbelt are controlled according to the vehicle collision state, for example, the vehicle collision state is classified into collision levels. Therefore, the opening state of the airbag can be controlled according to the corresponding collision level when the vehicle is in a collision state. For example, according to the severity of the collision of the vehicle, the vehicle collision level can be classified into three levels, including severe, relatively severe, and general. For example, severe can be defined as a collision that can cause serious injury to the occupant, relatively severe can be defined as a collision that can cause some injury to the occupant, and general can be defined as a collision that does not cause injury to the occupant. At this time, if the vehicle is in a severe collision, the airbag and seatbelt control unit can be triggered to release the airbag and pre-tighten the seatbelt, thereby improving the safety protection of the occupant. If the vehicle is in a general collision, the airbag and seatbelt control unit can not be triggered. Through the comparison and identification of the collision degree, the safety protection of the occupant is improved, and the waste of airbag resources is avoided.

[0130] In some embodiments, the vehicle collision sensing module at least includes:

[0131] A vehicle external state sensing module is used to sense the vehicle external collision state when the vehicle is in a collision state.

[0132] A vehicle internal state confirmation module is used to obtain the vehicle internal collision state through the in-vehicle camera, the seat sensors, and the seatbelt sensors.

[0133] In the example embodiment, when the collision situation of the vehicle in a collision state is determined, the vehicle external collision state when the vehicle is in a collision state can be sensed by the vehicle collision state sensing module, and the vehicle internal collision state can be obtained by the vehicle internal state confirmation module calling the in-vehicle camera, the seat sensors, and the seatbelt sensors. In this way, when the vehicle is in a collision state, the vehicle external collision state and the vehicle internal collision state can be obtained, thereby facilitating the implementation of safety protection measures for the occupant and improving the safety protection of the occupant when the vehicle is in a collision state.

[0134] In some embodiments, the vehicle collision state sensing module includes:

[0135] A wheel speed sensor is used to measure the wheel speed, wheel angle, and wheel rolling direction of the vehicle.

[0136] A deceleration sensor is used to measure the acceleration, deceleration, and vibration of the vehicle.

[0137] A tire pressure sensor is used to monitor the tire pressure in real time.

[0138] a body displacement sensor for monitoring the position change of the vehicle body relative to the axle or the ground;

[0139] a rotation angle sensor for detecting the rotation angle of the vehicle body;

[0154] The present disclosure provides a vehicle collision protection method applied to a vehicle collision protection system, which comprises a vehicle collision protection seat, a vehicle collision sensing module, and a seat resetting control unit. The vehicle collision protection seat comprises a seat body, a sliding rail device, and a spring device. The seat body is located on the sliding rail device, and the spring device is located below the seat body and is fixedly connected with the seat body. Figure 9 The vehicle collision protection method according to an exemplary embodiment is shown in the flowchart of FIG. 1. As shown in FIG. 1, the vehicle collision protection method comprises the following steps. Figure 9

[0155] Step 90: detecting the vehicle collision state sensed when the vehicle collides through the vehicle collision sensing module.

[0156] Step 91: controlling the triggering state of the spring device of the vehicle collision protection seat through the seat resetting control unit according to the vehicle collision state, so that the spring device triggers the resetting of the seat body when the vehicle collides. The vehicle collision state comprises a vehicle external collision state and a vehicle internal collision state.​

[0157] In the present exemplary embodiment, the vehicle collision protection seat comprises 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 below the seat body and is fixedly connected with the seat body; a vehicle collision sensing module is configured to detect a vehicle collision state sensed when the vehicle collides; a seat reset control unit is configured to control a triggering state of the spring device of the vehicle collision protection seat according to the vehicle collision state, so that the spring device triggers to reset the seat body when the vehicle collides; wherein the vehicle collision state comprises a vehicle external collision state and a vehicle internal collision state. In the present application, when protecting the person sitting in the vehicle, the seat body that can slide on the slide rail is adopted, and the spring device is installed below the seat body. When the vehicle collides, the seat reset control unit can control the triggering state of the spring device of the vehicle collision protection seat according to the vehicle collision state, so that the spring device triggers to reset the seat body when the vehicle collides, to buffer the inertia brought by the vehicle collision, thereby playing a role of protecting the person sitting in the vehicle by buffering the inertia and resetting the seat.

[0158] In some embodiments, comprising:

[0159] The opening state of the airbag and the pretightening state of the safety belt are controlled by the airbag and safety belt control unit according to the vehicle collision state.

[0160] In the present exemplary embodiment, when the vehicle collides and the person sitting in the vehicle needs to be protected, the opening state of the airbag and the pretightening state of the safety belt can be controlled according to the vehicle collision state. For example, the vehicle collision state is divided into collision levels. Therefore, the opening state of the airbag can be controlled according to the corresponding collision level when the vehicle collides. For example, according to the severity of the vehicle collision, the vehicle collision level can be divided into three levels, including severe, relatively severe and general. For example, severe can be defined as the collision can cause serious injury to the person sitting in the vehicle, relatively severe can be defined as causing some injury to the person sitting in the vehicle, and general can be defined as not causing injury to the person sitting in the vehicle. At this time, if the vehicle collides severely, the airbag and safety belt control unit can be triggered to release the airbag and pretighten the safety belt, thereby improving the safety protection of the person sitting in the vehicle. If the vehicle collides generally, the airbag and safety belt control unit can not be triggered. Through the comparison and identification of the collision degree, it is beneficial to improve the safety protection of the person sitting in the vehicle while avoiding waste of airbag resources.

In this way, when the vehicle is in collision, the vehicle exterior collision state and the vehicle interior collision state can be obtained, thereby facilitating the safety protection measures for the occupants and further improving the safety protection for the occupants when the vehicle is in collision.

A large number of sensors can obtain the driving state information of the vehicle before the collision occurs during driving. For example, 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, torque output by the vehicle bearing, motor and engine, etc. Thus, through the analysis and judgment of the driving state information, it is beneficial to more accurately analyze the possible collision situation when the vehicle collides.

[0174] In some embodiments, the vehicle exterior collision state when the vehicle collides is sensed by a vehicle collision state sensing module, which includes:

[0175] The vehicle exterior sensing and data providing module calls the camera and radar of the vehicle to obtain the distance between the external vehicle and the vehicle, and according to the distance change between the external vehicle and the vehicle and the driving state information of the vehicle sensed by the vehicle collision state sensing module, evaluates the relative speed between the vehicle and the external vehicle and the absolute speed of the external vehicle, and provides the analysis data corresponding to the relative speed between the vehicle and the external vehicle and the absolute speed of the external vehicle to the passenger passive protection evaluation module; wherein the driving state information of the vehicle includes 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, torque output by the vehicle bearing, motor and engine;

[0178] The vehicle passive protection evaluation module evaluates the collision result of the vehicle according to the relative speed of the vehicle and the external vehicle and the absolute speed of the external vehicle provided by the vehicle external sensing and data providing module and the momentum and impulse of the external vehicle when colliding with the vehicle provided by the vehicle front and rear side collision sensing module;

[0179] The vehicle comprehensive system balancing module receives the evaluation result of the vehicle passive protection evaluation module and determines the optimal vehicle control strategy from the perspective of the whole vehicle according to the relative speed of the vehicle and the external vehicle and the absolute speed of the external vehicle provided by the vehicle external sensing and data providing module and the momentum and impulse of the external vehicle when colliding with the vehicle provided by the vehicle front and rear side collision sensing module, and changes the driving state of the vehicle.

[0180] In the present exemplary embodiment,

[0181] In terms of protecting the safety of the occupants, the following methods can be used:

[0182] When the passengers in the vehicle are in a normal sitting position and are wearing seat belts, the airbags and seat belts are pre-tightened in time according to the intensity, position and direction of the collision in the normal mode, and at the same time, the vehicle body makes the greatest effort to resist the collision, such as releasing the brake, reducing the collision by moving backward, or actively steering to face the side collision to reduce the high-intensity damage of the front collision, or accelerating or decelerating to escape in time when a large truck collides and tilts, and opening all the airbags to resist the damage caused by the tilting of the truck.

[0183] When the passengers in the vehicle are in a zero-gravity state, the motor control is quickly released, the leg support is returned to its original position, and the hydraulic rod of the seat is relaxed. A motor lifting device is installed at the back of the zero-gravity seat to lift the seat back to its original position. At the same time, the seat air curtains on both sides of the seat are quickly opened to wrap around the passengers, and the front air curtains at the leg support position are opened to prevent leg injuries.

[0184] When the rear passengers are watching a pad without wearing seat belts, the head airbags of the front and rear seats are quickly popped out, and the lower airbags on the rear side of the front seat are popped out to prevent the rear passengers from hitting the pad and flying out of the vehicle body.

[0185] The vehicle comprehensive system balancing module balances the internal and external conditions of the vehicle, evaluates the possibility of external collision intrusion and the degree of intrusion and damage, and evaluates the possibility of internal vehicle personnel damage and the best and worst conditions. Then, through calculation and comprehensive processing, the steering, acceleration, brake, seat belt and airbag are executed to optimize the survival strategy for the passengers and the vehicle body, and the execution parameters are transferred to the vehicle passive protection execution module to control each parameter.

[0186] Finally, the vehicle comprehensive system balance module, in receiving the evaluation results of the vehicle passive protection evaluation module, then according to the comprehensive results of the vehicle external induction and data providing module, the vehicle front and rear side collision induction module, the vehicle brake induction module, etc., in finally starting from the whole vehicle angle, determines the optimal control strategy, changes the driving state of the car, through acceleration or deceleration or steering while starting the ESP system, and changes the passenger seating state in the car, and timely makes the most effective and safe execution action, to ensure that the personnel in the car achieve the optimal protection possibility.

[0187] One case, the front auxiliary driving seat is in a zero-gravity state, and the rear seat is in a normal seat state. The control execution operation is to quickly lower the zero-gravity state, and simultaneously start the safety belt pretensioning and airbag ejection operation.

[0188] One case, the front auxiliary driving seat is in a zero-gravity state, and the rear seat is in a normal seat state. The control execution operation is to quickly lower the zero-gravity state, and simultaneously start the safety belt pretensioning and airbag ejection operation.

[0189] One case, the front auxiliary driving seat is in a zero-gravity state, and the rear seat is in a normal seat state. The control execution operation is to quickly lower the zero-gravity state, and simultaneously start the safety belt pretensioning and airbag ejection operation.

[0190] Second, when the vehicle body is in a collision or sudden deceleration situation, the vehicle passive protection evaluation module simultaneously receives the data of the vehicle internal state confirmation module, simultaneously receives the acceleration and brake data provided by the vehicle acceleration and brake induction module, and simultaneously receives the data of the vehicle external induction and data providing module, in combination with the information provided by the vehicle front and rear side collision induction module and the vehicle steering induction module, performs comprehensive analysis and evaluation, and proposes at least three optimal processing methods for rapidly changing the state in the vehicle to protect the passengers in the vehicle.

[0191] Among them, the three rapid changes in the state in the vehicle can include:

[0192] When the passengers in the vehicle are in a normal sitting position and are all wearing safety belts, according to the normal mode according to the intensity, position and direction of the collision, timely open the airbag and safety belt pretensioning, and at the same time, the vehicle body makes the greatest effort to resist the collision, such as brake release, through rear retreat to reduce the collision, or actively steering to face the side collision to reduce the high-intensity damage of the front collision, or timely taking acceleration or deceleration to escape when a large truck collides and tilts, and opening all airbags to resist the tilting pressure damage of the truck.

[0193] When the passenger in the car has a zero-gravity seat, quickly through the release of the motor control, the leg rest back position, while the seat zero-gravity hydraulic rod relaxation, the installation of motor lifting device behind the zero-gravity seat, the zero-gravity back position, while the seat on both sides of the seat air curtain quickly open, wrapped around the passengers, the leg rest part of the front air curtain open, prevent leg injury.

[0194] When the rear passenger is watching the pad, the seat belt is not buckled, at this time, the front seat rear seat head air bag quickly pops out, the front seat rear lower air bag pops out, preventing the rear passenger from hitting the pad and flying out of the car body.

[0195] Among them, the optimal survival strategy can be generated by the vehicle comprehensive system balancing module. For example, the vehicle comprehensive system balancing module obtains the inside and outside of the vehicle, and conducts external and internal evaluation, evaluates the possibility of external collision intrusion and intrusion depth and damage, and internally evaluates the possibility of vehicle personnel damage and the worst and optimal state, and then through the calculation of comprehensive processing, the steering, acceleration, brake, seat belt, air bag are executed to optimize the survival strategy of passengers and vehicle body.

[0196] Finally, the vehicle comprehensive system balancing module, after receiving the evaluation result of the vehicle passive protection evaluation module, then according to the comprehensive result of the vehicle external sensing and data providing module, vehicle front and rear side collision sensing module, etc., finally from the whole vehicle angle, determine the optimal control strategy, change the driving state of the car, through acceleration or deceleration or steering while starting ESP system, and change the passenger sitting state in the car, make the most effective and safe execution action in time, ensure the optimal protection possibility of the personnel in the car.

[0197] Among them, when the personnel in the car are protected, the following situations can be included:

[0198] The first case is that the front auxiliary driving seat is in a zero-gravity state, and the rear seat is in a normal seat state control execution operation, which quickly lowers the zero-gravity state, and starts the seat belt pretensioning and air bag popping operation.

[0199] The second case is that the front auxiliary driving seat is in a zero-gravity state, and the rear seat is watching the display screen of the front seat and has not buckled up. This case needs to quickly complete the lowering of the front seat, and the rear seat side air bag wraps the rear passenger, and the rear air bag pops out from the bottom to fasten the legs of the rear passenger, preventing it from flying forward.

[0200] The third case, the rear seat is in the zero-gravity position, the front seat is folded or not folded, and the rear seat passenger is not buckled up. At this time, the leg rest can be quickly folded, the motor is powered off, so that the leg rest quickly returns to the original position, and the rear auxiliary zero-gravity hydraulic rod is quickly unloaded and returns to the original position. At the same time, in order to speed up the return speed, a bouncing device is arranged on the rear seat position. For example, a spring device, when the collision occurs, the spring device quickly bounces away, ensuring that the seat returns to the original position.
