Description

TECHNICAL FIELD

[0001] The present application relates to the field of vehicle collision automatic avoidance, and in particular to a vehicle seat assembly, a vehicle and a collision automatic avoidance method. BACKGROUND

[0002] With the increase in the number of vehicles on the road, traffic accidents occur more and more frequently. When a vehicle is involved in a traffic accident, although seat belts and airbags can alleviate some of the impact caused by the collision, when the vehicle collides with a long penetrating object, the penetrating object can easily cause harm to the passengers. In this case, seat belts and airbags alone cannot guarantee the safety of the passengers.

[0003] Currently, there are vehicle seats that can automatically adjust their positions in a straight line direction according to the situation of the collision. By automatically adjusting the position of the seat when a collision occurs, the impact force caused by the collision and the damage caused by the penetrating object can be reduced. However, due to the limited space for avoidance, and the limited flexibility of the seat when avoiding in the front, back, left and right directions, in the case of a long penetrating object, the seat often cannot effectively protect the passengers.

[0074] Please refer to Figure 1 , Figure 1 The structure of the vehicle seat assembly according to the embodiment of the present application is shown in the schematic diagram. The seat assembly includes a seat 1, a motor 2, and a curved moving track. The seat 1 is provided with a communication component for obtaining an avoidance position by communicating with the processor of the vehicle. The avoidance position is another position on the curved moving track and different from the initial position of the seat 1. The motor 2 is connected to the seat 1 and used to drive the seat 1 from the initial position to the avoidance position by moving along the curved moving track.

[0075] In the embodiment of the present application, when the vehicle is hit, the communication component on the seat can obtain signals from the body processor to drive the motor to move the seat to the avoidance position, thereby reducing the impact force caused by the impact. In the case of an impact object carrying a penetrating object, the movement of the seat along the curved moving track can effectively avoid the penetrating object, thereby improving the safety of the vehicle when it is hit.

[0076] In a specific embodiment, each seat corresponds to two motors, each of which is connected to the bottom of the seat. The curved moving track is a double-track structure, and the two motors are in contact with the two tracks of the curved moving track, respectively. The two motors drive the seat to move on the double-track.

[0077] In another specific embodiment, the avoidance position can be located at the end of the curved moving track or at any position on the curved moving track. After receiving the instruction from the processor of the vehicle, the communication component on the seat moves to the avoidance position for avoidance. In the case that the avoidance position is located at any position on the curved moving track, the avoidance can be more flexible to cope with different impact situations.

[0078] In one embodiment, please refer to Figure 1 , Figure 1 The structure of the vehicle seat assembly is shown in the schematic view. The curved moving track includes a first track 3, a second track 4, a third track 5, and a fourth track 6.

[0079] The first track 3 is used to connect the initial position and the first target position. In the case that the seat 1 is located at the initial position and faces the front of the vehicle, the first target position is located in front of the left side of the seat 1. The second track 4 is used to connect the initial position and the second target position. In the case that the seat 1 is located at the initial position and faces the front of the vehicle, the second target position is located in front of the right side of the seat 1. The third track 5 is used to connect the initial position and the third target position. In the case that the seat 1 is located at the initial position and faces the front of the vehicle, the third target position is located behind the left side of the seat 1. The fourth track 6 is used to connect the initial position and the fourth target position. In the case that the seat 1 is located at the initial position and faces the front of the vehicle, the fourth target position is located behind the right side of the seat 1.

[0080] In the embodiment of the present application, four sets of curved moving tracks are provided. In the case that the seat faces the front of the vehicle, the four sets of curved moving tracks are used to connect the initial position and the target position of the seat, respectively. The target position can become the selected avoidance position. The four sets of curved moving tracks provide the basis for the avoidance function of the seat. At the same time, the multiple sets of curved moving tracks improve the flexibility of the seat avoidance when the vehicle is impacted.

[0081] In one specific embodiment, the vehicle seat assembly includes four sets of curved moving tracks. The target position is located on the curved track. The target position can be located at any position on the curved track. The specific position is determined by the processor of the vehicle according to the actual impact situation. The first target position is located in front of the left side of the seat. The first track also extends from the initial position of the seat to the first target position in front of the left side of the seat. However, the target position is not necessarily located at the end of the first track. The second target position is located in front of the right side of the seat. The second track extends from the initial position of the seat to the second target position. The third target position is located behind the left side of the seat. The third track extends from the initial position of the seat to the third target position. The fourth target position is located behind the right side of the seat. The fourth track extends from the initial position of the seat to the fourth target position.

[0082] In one embodiment, please refer to Figure 2 , Figure 2 The motor structure of the embodiment of the application is shown in a top view, and the motor 2 comprises a control assembly 7, a fixing assembly, and a moving assembly 8;

[0083] The fixing assembly is used to fix the motor 2 on the curved moving track when the motor 2 stops moving.

[0084] The moving assembly 8 is used to drive the seat 1 to move along the curved moving track.

[0085] The control assembly 7 is used to move the fixing assembly.

[0086] In the embodiment of the application, the motor executes the avoidance instruction of the processor of the vehicle, controls the movement and stop of the seat on the curved moving track, and the motor is provided with the fixing assembly and the control assembly, so that the motor can be directly fixed on the curved moving track when the motor stops moving, thereby improving the stability of the seat and the experience of the user.

[0087] In one specific embodiment, the motor is in a spherical shape, the seat is located above the motor, the motor is connected with the seat, and the motor comprises a moving assembly. When receiving the avoidance instruction of the processor of the vehicle, the motor starts to move, and the spherical motor rolls on the curved moving track, thereby driving the seat to move.

[0088] In another specific embodiment, the motor comprises a fixing assembly and a control assembly, and the fixing assembly is located at two ends of the control assembly. When the motor moves, the control assembly controls the fixing assembly to retract into the motor, so as not to hinder the normal movement of the motor. When the motor stops, the control assembly controls the fixing assembly to be lowered, so as to form a locking structure with the curved moving track, thereby achieving the purpose of fixing the motor.

[0089] In one embodiment, please refer to Figure 3 and Figure 4 , Figure 3 The sawtooth track surface of the embodiment of the application is shown in a top view, Figure 4 The sawtooth track surface of the embodiment of the application is shown in a side view, and the curved moving track comprises a sawtooth track surface, and the sawtooth track surface is a track surface in contact with the motor 2.

[0090] The fixing assembly is used to form a locking structure with the sawtooth groove of the sawtooth track surface when the motor 2 stops moving.

[0091] In the embodiment of the present application, the surface of the curved moving track in contact with the motor is sawtooth-shaped, which can be matched with the fixed component of the motor to form a locking structure with the sawtooth groove, so as to fix the motor at the target position of the curved moving track and improve the stability of the seat.

[0092] In a specific embodiment, the side surface of the motor is gear-shaped, which can be complementary to the sawtooth track surface structure, so that the gear-shaped motor rolls forward on the sawtooth track surface to make the movement more stable.

[0093] In another specific embodiment, the motor is made of ferromagnetic metal, and an electromagnet strip is attached in the gap of the curved moving track. When the motor stops moving, the fixed component is lowered to form a locking structure with the sawtooth groove of the sawtooth track surface, and the electromagnet strip is electrified to generate strong magnetic force to attract the metal motor, thereby fixing the motor.

[0094] In an embodiment, please refer to Figure 5 , Figure 5 The side view of the locking structure of the embodiment of the present application is shown, the fixed component includes a first fixing part 9 and a second fixing part 10, the first fixing part 9 is used to form a first locking structure with the first sawtooth groove 11 when the motor 2 stops moving, the second fixing part 10 is used to form a second locking structure with the second sawtooth groove 12 when the motor 2 stops moving, the first sawtooth groove 11 is located in the forward direction of the motor 2 along the curved moving track, and the second sawtooth groove 12 is located in the backward direction of the motor 2 along the curved moving track.

[0095] In the embodiment of the present application, the fixed part of the fixed component forms two locking structures with the sawtooth groove, respectively in the forward direction and the backward direction of the motor, so that the motor cannot move forward and backward after locking, thereby achieving the purpose of fixing the motor.

[0096] In a specific embodiment, the two locking structures are located in the forward direction and the backward direction of the motor, and when the motor stops moving, the control component controls the first fixing part and the second fixing part to be lowered, the first fixing part is clamped into the first sawtooth groove to form a first locking structure, and the second fixing part is clamped into the second sawtooth groove to form a second locking structure.

[0097] In another specific embodiment, the two locking structures are located on the left and right sides of the motor's forward direction. When the motor stops moving, the control component controls the first and second fixing parts to lower. The first fixing part on the left side of the motor's forward direction passes through the first serrated groove and is locked by the adjacent serrations of the first serrated groove, forming the first locking structure. Simultaneously, the second fixing part on the right side of the motor's forward direction passes through the second serrated groove, forming the second locking structure. When the motor moves, the fixing parts on the left and right sides of the motor's forward direction are raised. Because the fixing components are located on the left and right sides of the motor at this time, the motor's rolling forward does not affect the motor. The fixing components do not need to retract into the motor; they only need to be raised so as not to hinder the normal movement of the motor.

[0098] In one embodiment, see Figure 1 , Figure 1 The diagram shows a vehicle seat assembly structure according to an embodiment of the present invention. The first track 3, the second track 4, the third track 5, and the fourth track 6 all have a dual-track structure.

[0099] In an embodiment of the present invention, the curved moving track adopts a double-track structure. Compared with a single-track structure, the double-track structure makes the seat more stable during movement, improving the user's experience and comfort.

[0100] In one specific embodiment, the dual-track structure has two curved moving tracks, and two motors respectively contact the two curved moving tracks, with the two motors driving the same seat to move along the curved moving tracks.

[0101] This invention also provides a vehicle, which is equipped with the vehicle seat assembly.

[0102] In an embodiment of the present invention, the vehicle is provided with one or more of the above-mentioned vehicle seat assemblies, which can control the vehicle seat to avoid collisions.

[0103] In one embodiment, the vehicle is equipped with a first sensor, a second sensor, a third sensor, and a fourth sensor; the first sensor is disposed on a first impact surface of the vehicle and is used to acquire an image of an impact object facing the first impact surface; the second sensor is disposed on a second impact surface of the vehicle and is used to acquire an image of an impact object facing the second impact surface, wherein the second impact surface is a surface opposite to the first impact surface; the third sensor is disposed on a third impact surface of the vehicle and is used to acquire an image of an impact object facing the third impact surface, wherein the third impact surface is a surface adjacent to the first impact surface; the fourth sensor is disposed on a fourth impact surface of the vehicle and is used to acquire an image of an impact object facing the fourth impact surface, wherein the fourth impact surface is a surface opposite to the third impact surface.

[0104] The first sensor, the second sensor, the third sensor and the fourth sensor are configured to communicate with a processor of the vehicle, and the processor is configured to determine the avoidance position corresponding to the vehicle seat assembly.

[0105] In the embodiment of the present application, four sensors are arranged on the vehicle to obtain images of the impact object towards the first impact surface, the second impact surface, the third impact surface and the fourth impact surface, so as to determine the position where the vehicle is about to be impacted. The four sensors can monitor the situation around the vehicle in all directions. The four sensors can be arranged on the outside of the vehicle or on the inside of the vehicle.

[0106] In a specific embodiment, each group of sensors includes an image sensor and a non-image sensor. For example, the first sensor includes a camera and a radar. The camera can capture a picture of the impact object to predict the impact position or impact surface of the impact object. For example, if the camera in the first sensor captures an image of an impact object approaching, it can be predicted that the impact surface is the first impact surface. The radar can be used to measure the impact speed of the impact object.

[0107] In another specific embodiment, when the seat faces the front of the vehicle, the first impact surface can be the surface on the outside of the vehicle in front of the seat, the second impact surface can be the surface on the outside of the vehicle behind the seat, the third impact surface can be the surface on the left side of the vehicle, and the fourth impact surface can be the surface on the right side of the vehicle.

[0108] In another specific embodiment, the vehicle further comprises an impact sensing sensor. The impact sensing sensor is configured to monitor whether the vehicle has been substantially impacted. For example, when the vehicle is indeed impacted to a certain extent and the vehicle feels the impact, the impact sensing sensor sends an impact signal to indicate that the vehicle has been impacted and transmits the impact signal to the processor of the vehicle.

[0109] In an embodiment, the vehicle further comprises a fifth sensor. The fifth sensor is configured to obtain a target image of a target object, and the target object is an object on the seat of the vehicle seat assembly. The fifth sensor is further configured to communicate with the processor of the vehicle.

[0110] In the embodiment of the present application, a fifth sensor is arranged in the vehicle. The fifth sensor can obtain the physical information of the passenger sitting on the seat of the vehicle seat assembly, such as age and gender. Obtaining the physical information of the passenger can enable the processor of the vehicle to generate different seat movement instructions according to different passengers, so as to ensure the safety of the vehicle and the comfort of the passenger at the same time when the vehicle is impacted.

[0111] In a specific embodiment, the fifth sensor can be a camera, which takes a picture of the passenger after the vehicle starts, and sends the picture of the passenger to the processor of the vehicle, which identifies the age and gender of the passenger by using a pre-trained model.

[0112] In another specific embodiment, the fifth sensor can be a millimeter wave radar, which emits a linear frequency pulse to the chest of the passenger after the vehicle starts, acquires the heart rate and breathing rate information of the passenger, and transmits the heart rate and breathing rate information of the passenger to the processor of the vehicle, which analyzes the physical health condition of the passenger.

[0113] The embodiment of the present application also provides a collision automatic avoidance method, please refer to Figure 6 , Figure 6 The embodiment of the present application shows a flowchart of the collision automatic avoidance method, and the above method comprises:

[0114] Step S601: obtaining an image of the impact object based on the first sensor, the second sensor, the third sensor or the fourth sensor;

[0115] Step S602: determining the impact surface of the impact object based on the image of the impact object;

[0116] Step S603: predicting the impact angle of the impact object based on the image of the impact object, wherein the impact angle is the angle between the trajectory of the impact object hitting the impact surface and the impact surface;

[0117] Step S604: predicting the impact influence area according to the impact angle, wherein the impact influence area represents the damage space formed after the impact object breaks through the impact surface;

[0118] Step S605: determining the seat movement instruction based on the impact surface and the impact influence area;

[0119] In the embodiment of the present application, when the impact object is detected to approach, the impact surface and the impact influence area of the impact object are first determined according to the data collected by the sensor, which can provide a basis for the seat avoidance. With the impact surface and the impact influence area, the avoidance position that can make the passenger not be injured can be determined by the calculation of the processor of the vehicle, so as to generate the instruction indicating the seat to move to the avoidance position, thereby improving the safety when the vehicle is collided.

[0120] In a specific embodiment, the camera in the four groups of sensors takes a picture of the impact object. When the camera of the first sensor takes a picture of the impact object, and the other cameras do not take a picture, it is determined that the impact surface is the first impact surface. The first sensor transmits the picture of the impact object to the processor of the vehicle. The processor of the vehicle analyzes the picture to obtain the impact angle, for example, the analysis obtains an impact angle of 45 degrees. Then, according to the impact angle, the area that may be damaged if the penetrating object carried by the impact object or the front windshield of the vehicle is broken due to the impact of the impact object, i.e., the impact area, is predicted. The processor of the vehicle generates a seat moving instruction to make the passenger not be injured according to the information of the impact surface and the impact area.

[0121] Step S606: In the case of receiving the impact signal, the above-mentioned seat moving instruction is transmitted to the communication component on the seat, so that the above-mentioned seat moves to the avoidance position in the above-mentioned seat moving instruction.

[0122] In the embodiment of the present application, the seat moves according to the seat moving instruction in response to the impact signal. In the case that the impact object is too close or the impact is too light to cause injury to the passenger, unnecessary movement of the seat can be avoided, and unnecessary loss to the passenger can be avoided.

[0123] In a specific embodiment, when the camera takes a picture of the impact object outside the vehicle, the seat moving instruction is obtained according to the above-mentioned series of judgments. However, at this time, the vehicle processor only generates the seat moving instruction and does not send it to the communication component on the seat. When the impact occurs but the impact is too light, the impact sensing sensor does not generate an impact signal. The vehicle processor still does not transmit the seat moving instruction to the communication component on the seat. At this time, the seat does not move. When the impact sensing sensor sends an impact signal and transmits the impact signal to the processor of the vehicle, the vehicle processor sends the seat moving instruction generated in advance to the communication component on the seat. The seat executes the seat moving instruction to move and avoid the impact object.

[0124] In an embodiment, please refer to Figure 7 , Figure 7 The flowchart for determining the seat moving instruction in the embodiment of the present application is shown. The seat moving instruction is determined based on the impact surface and the impact area, and includes:

[0125] Step S701: generating a target moving instruction based on the impact surface. The target moving instruction is used to indicate that the seat moves away from the impact surface;

[0126] Step S702: generating the seat movement instruction based on the impact influence area and the target movement instruction, the seat movement instruction being used to instruct to move away from the impact surface to avoid the impact influence area.

[0127] In the embodiment of the present application, the target movement instruction generated according to the impact surface can effectively move the passenger away from the impact surface, thereby avoiding the injury caused by the impact to the passenger; the seat movement instruction determined according to the impact influence area and the target movement instruction can avoid the piercing object carried by the impact object, so as to prevent the piercing object from causing injury to the passenger, and the seat movement instruction determined based on the impact surface and the impact influence area can effectively protect the safety of the passenger in the vehicle impact.

[0128] In a specific embodiment, in the case that the seat faces the front of the vehicle, there are four target positions, which are respectively located at the left front, right front, left rear and right rear of the seat, when the first sensor for monitoring the front of the vehicle detects an impact object, the target movement instruction is first determined, the target movement instruction contains moving the seat to the left rear and right rear, and then the impact influence area, i.e. the area that may be injured if the impact object penetrates, is calculated by the processor of the vehicle according to the data information obtained by the first sensor, if the impact influence area is the right front and left rear, the determined seat movement instruction is used to instruct the seat to move to the right rear.

[0129] In another specific embodiment, in the case that the vehicle is impacted without accompanying the piercing object, for example, the vehicle is rear-ended on the road surface, then in the case that the seat faces the front of the vehicle, there are four target positions, which are respectively located at the left front, right front, left rear and right rear of the seat, since the rear of the vehicle is the impact surface when the vehicle is rear-ended, the target movement instruction is determined to instruct the seat to move to the left front or right front, and since there is no impact influence area, the target position of the right front can be preferentially selected as the avoidance position for the main driver position, so as to prevent the vehicle on the other lane from colliding with the vehicle again and causing injury to the passenger.

[0130] In an embodiment, please refer to Figure 8 , Figure 8 a flowchart for determining the first movement speed in the embodiment of the present application is shown, and before the seat movement instruction is determined based on the impact surface and the impact influence area, the method further comprises:

[0131] Step S801: obtaining a target image of a target object on the seat in the seat assembly of the vehicle based on the fifth sensor;

[0132] Step S802: identifying the target image to obtain the sign information of the target object;

[0133] Step S803: determining a first moving speed of the seat based on the sign information, the first moving speed being a minimum moving speed of the seat without causing harm to the target object.

[0134] In the embodiment of the application, the first moving speed is determined by identifying the sign information of the passenger, different moving strategies are made for different groups of people while ensuring the safety of the passenger, the comfort and experience of the user are improved, the first moving speed is a pre-set minimum moving speed without causing harm to the passenger, and it can be understood that the first moving speed can be different for different groups of people.

[0135] In a specific embodiment, the co-driver of the vehicle is provided with the vehicle seat assembly, the fifth sensor is a camera, and the camera is used to take pictures of the passenger after the vehicle starts. If the passenger is an old person, the first moving speed is determined based on a pre-set moving speed database, for example, 10 m / s. If the passenger is a young person, the first moving speed can be 15 m / s.

[0136] In another specific embodiment, the co-driver of the vehicle is provided with the vehicle seat assembly, the fifth sensor is a millimeter wave radar, and the millimeter wave radar is used to obtain the heart rate and breathing rate information of the passenger after the vehicle starts. The first moving speed is determined according to the heart rate and breathing rate information, for example, the passenger's heart rate is monitored to be 65 times per minute, there is no heart tremor, and the breathing rate is 35 times per minute. It can be determined that the passenger's physical condition is good, and the first moving speed is determined to be 17 m / s.

[0137] It can be understood that the sign information of the passenger and the numerical value of the first moving speed can form a one-to-one corresponding relationship and be stored in the moving speed database, which can be called as needed.

[0138] In an embodiment, please refer to Figure 9 , Figure 9 The flowchart for determining the moving speed of the seat in the embodiment of the application is shown, and after the image of the impact object is obtained, the method further includes:

[0139] Step S901: calculating the speed of the impact object based on the image of the impact object;

[0140] Step S902: determining a second moving speed based on the speed of the impact object, the second moving speed being a minimum moving speed of the seat to avoid harm from the impact object;

[0141] Step S903: determining the first moving speed as the moving speed of the seat when the first moving speed is greater than the second moving speed;

[0142] Step S904: In the case that the first moving speed is less than or equal to the second moving speed, the second moving speed is determined as the seat moving speed.

[0143] In the embodiment of the present application, the speed of the impact object is calculated to obtain the second moving speed, and the second moving speed is compared with the first moving speed to obtain the moving speed of the seat. If the moving speed of the impact object is greater, the moving speed of the seat is the same as the moving speed of the impact object. If the first moving speed is greater, the moving speed of the seat is the same as the first moving speed. Meanwhile, the safety attribute and the comfort attribute of the moving speed of the seat are considered, and the comfort of the passenger is ensured on the premise of ensuring the safety of the passenger.

[0144] In a specific embodiment, for example, the speed of the impact object is calculated by radar to be 12 m / s, and at this time, an old person is seated on the seat of the vehicle seat assembly, the processor of the vehicle determines that the first moving speed is 10 m / s and the second moving speed is 12 m / s. Considering that the speed of the impact object is 12 m / s when the impact object has not impacted outside the vehicle, if the impact occurs, the speed of the impact object will be attenuated and will be less than 12 m / s, so it is safe to determine the second moving speed as the moving speed of the seat.

[0145] In another specific embodiment, the second moving speed of the impact object is 12 m / s, and the first moving speed is determined to be 15 m / s. At this time, since 15 m / s is the comfortable speed acceptable to the passenger, the seat is moved at a speed greater than the speed of the impact object outside the vehicle in a comfortable case, so that the safety of the passenger can be better ensured. Therefore, in the above case, the first moving speed is used as the moving speed of the seat.

[0146] The seat moving instruction is determined based on the impact surface and the impact influence area, comprising:

[0147] The seat moving instruction is determined based on the impact surface, the impact influence area, and the seat moving speed.
