Description

Technical Field

[0001] The present application relates to the technical field of vehicles, and particularly to a seat quick return system and a vehicle. Background Art

[0002] Since zero-gravity seats can bring better comfort to passengers, they are accepted by the market and more and more products are being launched. Usually, vehicles only use zero-gravity seats when they are stationary.

[0003] However, if a zero-gravity seat is used during driving, since the backrest angle of the passenger is relatively large, in order to prevent accidents when using the zero-gravity seat during driving, it is necessary to adjust the zero-gravity seat to an angle that protects the safety of the passenger when a danger occurs.

[0004] How to adjust the zero-gravity seat to an angle that protects the safety of the passenger when a danger occurs is a technical problem that needs to be solved. Summary of the Invention

[0005] In view of this, the present application provides a seat quick return system and a vehicle.

[0006] In a first aspect, the present application provides a seat quick return system, which includes: a vehicle safety module, the vehicle's vehicle power supply, a quick return activation module, a wire harness box, a seat module, and a seat backrest motor; the quick return activation module is electrically connected to the seat backrest motor, and the wire harness for supplying power to the quick return activation module is electrically connected to the wire harness that passes through the wire harness box and supplies power to the seat module; the vehicle safety module is used to generate a first adjustment signal for the seat; the vehicle's vehicle power supply is used to charge the quick return activation module through the wire harness for supplying power to the quick return activation module; the quick return activation module is used to receive the first adjustment signal for the seat and provide a first current to the seat backrest motor according to the first adjustment signal for the seat; the seat backrest motor is used to control the seat to perform a first action according to the first current.

[0007] For the seat quick return system provided in this embodiment, the vehicle's vehicle power supply supplies power to the quick return activation module. When the vehicle safety module generates a first adjustment signal, the quick return activation module can quickly receive and process the first adjustment signal to generate a first current, and at the same time provide the first current to the seat backrest motor, so that the seat backrest motor can control the seat to be adjusted to a safe position. Moreover, the wire harness for supplying power to the quick return activation module is electrically connected to the wire harness that passes through the wire harness box and supplies power to the seat module, that is, the wire harness for supplying power to the quick return activation module is not arranged in the wire harness box. Therefore, there is no need to increase a large-current wire harness in the wire harness box. On the one hand, it can improve the efficiency of adjusting the seat to an angle that protects the safety of the passenger. On the other hand, it can reduce the diameter of the wire harness in the wire harness box, thereby reducing the occupied area of the wire harness in the wire harness box.

[0008] In a possible implementation, the vehicle's overall power supply is also used to supply power to the quick return activation module through the wiring harness that supplies power to the quick return activation module if the power of the quick return activation module is not greater than a preset power; or, if the capacitance stored power of the capacitor of the quick return activation module is not greater than a preset capacitance stored power, supply power to the quick return activation module through the wiring harness that supplies power to the quick return activation module.

[0009] For the seat quick return system provided in this embodiment, when the power of the quick return activation module is not greater than the preset power, the vehicle's overall power supply can supply power in a timely manner, avoiding the situation that it stops working due to power exhaustion or cannot generate a large current due to insufficient power, and improving the overall stability of the system.

[0010] In addition, when the capacitance stored power of the capacitor of the quick return activation module is not greater than the preset capacitance stored power, the vehicle's overall power supply can supply power in a timely manner, avoiding the situation that a large current cannot be generated due to insufficient capacitance stored power, and improving the overall stability of the system.

[0011] In a possible implementation, the system further includes the vehicle's body module, and the seat module is electrically connected to the seat back motor; the vehicle's body module is used to generate a second adjustment signal for the seat; the vehicle's overall power supply is also used to supply power to the seat module through the wiring harness that supplies power to the seat module; the seat module is used to receive the second adjustment signal and provide a second current to the seat back motor according to the second adjustment signal; wherein, the first current is greater than the second current; the seat back motor is further used to control the seat to perform a second action according to the second current.

[0012] For the seat quick return system provided in this embodiment, during the normal driving of the vehicle, the body module generates a second adjustment signal, so that after the seat module receives the second adjustment signal, it can provide a second current to the seat back motor, so that the seat back motor controls the seat to perform a second action according to the second current, so as to accurately adjust the seat during the normal driving of the vehicle.

[0013] In a possible implementation, the seat module is further used to stop providing the second current to the seat back motor and send the first adjustment signal to the quick return activation module when the seat back motor controls the seat to perform a second action according to the second current and receives the first adjustment signal generated by the vehicle's overall safety module.

[0014] For the seat quick return system provided in this embodiment, the seat module needs to have the ability to judge the priority of multiple signals, determine that the priority of the first adjustment signal is higher than that of the second adjustment signal. During the process that the seat backrest motor controls the seat to perform a second action according to the second current, if the first adjustment signal is received, then stop providing the second current to the seat backrest motor, so as to avoid secondary injuries caused by the inertia or out-of-control of the seat.

[0015] In a possible implementation manner, the system further includes the vehicle body module of the vehicle. The seat module is connected to the quick return activation module; the vehicle body module of the vehicle is used to generate the second adjustment signal of the seat; the vehicle's entire vehicle power supply is also used to supply power to the seat module through the wire harness for supplying power to the seat module; the seat module is used to receive the second adjustment signal and send the second adjustment signal to the quick return activation module; the quick return activation module is used to receive the second adjustment signal and provide the second current to the seat backrest motor according to the second adjustment signal; the seat backrest motor is also used to control the seat to perform a second action according to the second current.

[0016] For the seat quick return system provided in this embodiment, by connecting the seat module and the quick return activation module, the seat module can receive the second adjustment signal and the first adjustment signal of the vehicle body module, and the quick return activation module can generate a current according to the received second adjustment signal or first adjustment signal and provide it to the seat backrest motor, so that the functional responsibilities of the seat module and the quick return activation module are single, reducing the development complexity. Moreover, if the seat action is abnormal, the problem can be quickly located by checking the seat module or the quick return activation module.

[0017] In a possible implementation manner, the seat module is further used to send the first adjustment signal to the quick return activation module when the seat backrest motor controls the seat to perform a second action according to the second current and receives the first adjustment signal generated by the vehicle's entire vehicle safety module; the quick return activation module is further used to determine the adjustment direction of the seat backrest when receiving the first adjustment signal. Among them, when the adjustment direction of the seat backrest is counterclockwise, provide the first current to the seat backrest motor according to the first adjustment signal of the seat, and when the adjustment direction of the seat backrest is clockwise, stop providing the second current to the seat backrest motor and provide the first current to the seat backrest motor according to the first adjustment signal of the seat.

[0018] The seat rapid return system provided in this embodiment can immediately send the first adjustment signal to the rapid return activation module after the seat module receives the first adjustment signal sent by the vehicle safety module. The rapid return activation module accurately controls the motor current by judging the adjustment direction of the backrest (clockwise or counterclockwise). When the adjustment direction of the backrest of the seat is counterclockwise, the first current is directly provided to the seat backrest motor, enabling the seat to perform rapid return. When the adjustment direction of the backrest of the seat is clockwise, the second current provided to the seat backrest motor is stopped, and the first current is provided to the seat backrest motor according to the first adjustment signal of the seat, avoiding the opposite directions of the first current and the second current and reducing the efficiency of the rapid return of the seat.

[0019] In a possible implementation, the rapid return activation module includes: a circuit board and a target component; wherein, the target component includes any one of a capacitor and a lithium battery; the circuit board is communicatively connected to the vehicle safety module for receiving the first adjustment signal; the vehicle's vehicle power supply is further used to charge the target component; the target component is arranged on the circuit board for providing the first current to the seat backrest motor according to the first adjustment signal.

[0020] In the seat rapid return system provided in this embodiment, the circuit board, as the core component of the rapid return activation module, establishes a stable communication connection with the vehicle safety module, enabling the first adjustment signal to be accurately and quickly sent to the circuit board. The circuit board sends the first adjustment signal to the capacitor. Since the capacitor has an energy storage function, the capacitor can quickly discharge after receiving the signal and provide the required first current for the seat backrest motor.

[0021] In addition, the lithium battery is arranged on the circuit board and serves as the energy source for the seat rapid return function. The lithium battery has a high energy density, a long service life, and stable discharge performance, so as to be able to provide the required first current for the seat backrest motor.

[0022] In a possible implementation, the system further includes: a first anti-backflow module and a second anti-backflow module; the first anti-backflow module is located between the seat backrest motor and the rapid return activation module and is electrically connected to the seat backrest motor and the rapid return activation module; the second anti-backflow module is located between the seat module and the seat backrest motor and is electrically connected to the seat module and the seat backrest motor.

[0023] In the seat rapid return system provided in this embodiment, anti-backflow modules are added between the seat module and the seat backrest motor and between the rapid return activation module and the seat backrest motor, which can prevent current backflow when the seat module and the rapid activation module supply power to the seat backrest motor respectively, and avoid damage to the seat module and the rapid return activation module.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0041] Please refer to Figure 2 , Figure 2 It is a schematic structural diagram of a seat return system provided by the related art.

[0042] Combined with Figure 1 and Figure 2 shown, in the related art, the vehicle power supply is often directly used to supply power to the seat module, and then the seat module generates current to drive the seat back motor so that the seat back motor drives the seat to return.

[0043] However, since the seat back motor needs to adjust 20° within 0.5 - 0.7S, two 600W seat back motors are required to support the seat return, and in some cases, two 360W motors are used by some suppliers. The voltage on the vehicle is generally 12V - 14V. If it is necessary to support the above high-power seat back motors, a wire harness of 5 - 10 square millimeters needs to be added in the wire harness box to support a current of more than 50A.

[0044] However, the long slide rail wire harness box itself has a limited support for the wire harness diameter. If the wire harness with a cross-sectional area of 5 - 10 square millimeters is added, when the wire harness diameter increases, the space inside the wire harness box may become tight, resulting in overfilling of the wire harness and preventing the installation of other functional wires, thus affecting the seat adjustment efficiency.

[0045] Based on this, the present application provides a seat quick return system.

[0046] Please refer to Figure 3 , Figure 3 which is a schematic structural diagram of the seat quick return system provided by the embodiment of the present application. As shown in Figure 3 , the seat quick return system includes: a vehicle safety module 100, a vehicle power supply 200 of the vehicle, a quick return activation module 300, a wire harness box 400, a seat module 500, and a seat back motor 600; the quick return activation module 300 is electrically connected to the seat back motor 600, and the wire harness for supplying power to the quick return activation module 300 is electrically connected to the wire harness passing through the wire harness box 400 and supplying power to the seat module 500; the vehicle safety module 100 is configured to generate a first adjustment signal for the seat; the vehicle power supply 200 of the vehicle is configured to charge the quick return activation module 300 through the wire harness for supplying power to the quick return activation module 300; the quick return activation module 300 is configured to receive the first adjustment signal for the seat and provide a first current to the seat back motor 600 according to the first adjustment signal for the seat; the seat back motor 600 is configured to control the seat to perform a first action according to the first current.

[0047] In the present application, the vehicle safety module 100 can be used to ensure the safety of the vehicle. Among them, the vehicle safety module 100 can be a Body Control Module (BCM), or an Electronic Stability Controller (ESC), etc. The vehicle safety module 100 can also be a system for ensuring vehicle safety. That is to say, the vehicle safety module 100 can be composed of devices such as sensors and body controllers in the vehicle, and no specific limitation is made here.

[0048] The first adjustment signal can represent a signal for adjusting the seat of the vehicle. Among them, the first adjustment signal is generated by the vehicle safety module 100 receiving a signal that the vehicle is about to collide.

[0049] In specific implementation, there are two stages before and after the vehicle collision: Stage 1: Active safety avoidance of the seat before the collision; Stage 2: Cooperative work of passive safety components after the collision.

[0050] For Stage 1: Within the time period of 0.5 to 0.7 seconds before it is determined that a vehicle collision occurs, the vehicle safety module 100 can cooperate with other detection modules configured in the vehicle to generate a first adjustment signal. Among them, the other detection module can be a sensor configured at the front of the vehicle, and this sensor can detect the surrounding environment of the vehicle in real time. When the vehicle is about to collide with an obstacle, the vehicle safety module 100 of the vehicle can no longer carry out thorough collision avoidance actions (such as adjusting the steering wheel direction, active braking, etc.). At this time, the vehicle safety module 100 of the vehicle can generate a first adjustment signal and send the first adjustment signal to the quick return activation module 300. After receiving the first adjustment signal, the quick return activation module 300 can provide a first current (high current) to the seat back motor 600, so that the seat can be adjusted to a safe position within a short time (such as 0.5 to 0.7 seconds, etc.).

[0051] For Stage 2: The passive safety components can be airbags, seat belts, etc. When a vehicle collision occurs, the airbag sensor will quickly sense the collision signal and transmit the signal to the electronic control device. After the electronic control device judges the severity of the collision, it will immediately send an ignition signal to inflate the airbag within an extremely short time to provide protection for the occupants. The seat belt can restrain the passenger's body to prevent the passenger from moving excessively or being thrown out of the vehicle during the collision. At the same time, the seat belt can also be used in conjunction with the airbag to improve the protection effect.

[0052] The wire harness box 400 can be a long slide rail wire harness box or other forms of wire harness boxes, and no specific limitation is made here. The wire harness box 400 can accommodate multiple wire harnesses, such as signal wires, power supply wire harnesses, etc.

[0053] The wire harness for supplying power to the seat module 500 passes through the wire harness box 400, and the wire harness for supplying power to the quick return activation module 300 does not pass through the wire harness box 400. Among them, the wire harness for supplying power to the seat module 500 can be split on the seat module 500, that is, it will be divided into two positive wire harnesses and two negative wire harnesses. One positive wire harness is connected to the seat module 500, and the other positive wire harness is connected to the quick return activation module 300; one negative wire harness is connected to the seat module 500, and the other negative wire harness is connected to the quick return activation module 300.

[0054] The vehicle's integrated power supply 200 can charge the quick return activation module 300 through the wiring harness that supplies power to the quick return activation module 300, to ensure that the quick return activation module 300 has the power to provide the first current. The quick return activation module 300 can supply the first current to the seat back motor 600 according to the first adjustment signal when the vehicle is about to collide. The seat back motor 600 can control the seat to perform a first action within a short time (such as 0.5 - 0.7, etc.) according to the first current, so that the seat is adjusted to a safe position. Among them, the first action can indicate controlling the backrest of the vehicle seat in the clockwise direction.

[0055] Please refer to Figure 4 and Figure 5 , Figure 4 is a schematic diagram of seat adjustment provided according to an embodiment of the present application. Figure 5 is another schematic diagram of seat adjustment provided according to an embodiment of the present application.

[0056] In this embodiment, Figure 4 represents the process of seat adjustment when the seat cushion skeleton is normal, Figure 5 represents the process of seat adjustment when the seat skeleton collapses. The seat can be a zero-gravity seat.

[0057] During the normal driving of the vehicle, the angle formed between the seat back and the ground is relatively small (such as Figure 4 30° in Figure 4 ). Due to the relatively small angle formed between the seat back and the ground, the protective performance of the seat belt will be greatly reduced, resulting in the inability to ensure the safety of passengers in the event of a vehicle collision. When the vehicle is about to collide, the vehicle integrated safety module 100 generates a first adjustment signal, and then the quick return activation module 300 sends the first current to the seat back motor 600 according to the first adjustment signal, so that the seat is adjusted by 20° within 0.5 - 0.7S, so that the angle formed between the seat back and the ground reaches

[0058] 50° in Figure 4 ), so that the seat belt installed on the backrest can protect the lives of passengers.

[0059] When the seat cushion skeleton collapses, through the quick return activation module 300, the seat is adjusted by 35° within 0.5 - 0.7S, so that the angle formed between the seat back and the ground reachesFigure 5 65° in

[0060] In a possible implementation, to ensure that the seat can be adjusted to a safe position within a short time (such as 0.5 - 0.7, etc.), the first current can be a current greater than A1, etc. There is no specific limitation here, which can be determined by the type of the backrest motor. That is, when the quick return activation module 300 receives the first adjustment signal, it can generate a current greater than A1, and then send it to the seat backrest motor 600, so that the seat backrest motor 600 can control the seat to perform the first action under the action of the large current.

[0061] In a possible implementation, the signal line (such as Figure 3 the dotted line in

[0062] The seat quick return system provided in this embodiment is powered by the vehicle's vehicle power supply to the quick return activation module. When the vehicle safety module generates the first adjustment signal, the quick return activation module can quickly receive and process the first adjustment signal to generate the first current, and at the same time provide the first current to the seat backrest motor, so that the seat backrest motor can control the seat to be adjusted to a safe position. And, the wire harness that powers the quick return activation module is electrically connected to the wire harness that passes through the wire harness box and powers the seat module, that is, the wire harness that powers the quick return activation module is not arranged in the wire harness box, so there is no need to increase the wire harness with large current in the wire harness box. On the one hand, it can improve the efficiency of adjusting the seat to an angle to protect the safety of passengers, and on the other hand, it can reduce the diameter of the wire harness in the wire harness box, thereby reducing the occupied area of the wire harness in the wire harness box.

[0063] In a possible implementation, the vehicle's vehicle power supply 200 is also used to supply power to the quick return activation module 300 if the power of the quick return activation module 300 is not greater than the preset power.

[0064] The preset power can be the power that needs to be charged for the quick return activation module 300 set in advance. Among them, the preset power can be the remaining power of the quick return activation module 300, such as 90%, 95%, etc. When the power of the quick return activation module 300 is not greater than the preset power, the vehicle's vehicle power supply 200 needs to charge the quick return activation module 300.

[0065] For the seat quick return system provided in this embodiment, the vehicle's vehicle power supply can supply power in a timely manner when the power of the quick return activation module is not greater than the preset power, avoiding the situation that it stops working due to power exhaustion or cannot generate a large current due to insufficient power, and improving the overall stability of the system.

[0066] In a possible implementation, the vehicle's vehicle power supply 200 is also used to supply power to the quick return activation module 300 if the capacitance stored power of the capacitor of the quick return activation module 300 is not greater than the preset capacitance stored power.

[0067] The preset capacitance stored power can be the capacitance stored power that needs to be charged for the quick return activation module 300 set in advance. Among them, the preset capacitance stored power can be the remaining capacitance stored power of the quick return activation module 300, such as 90%, 95%, etc. When the capacitance stored power of the capacitor of the quick return activation module 300 is not greater than the preset capacitance stored power, the vehicle's vehicle power supply 200 needs to charge the quick return activation module 300.

[0068] For the seat quick return system provided in this embodiment, the vehicle's vehicle power supply can supply power in a timely manner when the capacitance stored power of the capacitor of the quick return activation module is not greater than the preset capacitance stored power, avoiding the situation that the capacitance stored power is insufficient to generate a large current, and improving the overall stability of the system.

[0069] Please refer to Figure 6 , Figure 6 which is a schematic structural diagram of another seat quick return system provided according to an embodiment of the present application.

[0070] In a possible implementation, as Figure 6 shown, the system further includes the vehicle's body module 700, the seat module 500 is electrically connected to the seat back motor 600; the vehicle's body module 700 is used to generate a second adjustment signal for the seat; the vehicle's vehicle power supply 200 is also used to supply power to the seat module 500 through the wire harness for supplying power to the seat module 500; the seat module 500 is used to receive the second adjustment signal and provide a second current to the seat back motor 600 according to the second adjustment signal; wherein, the first current is greater than the second current; the seat back motor 600 is also used to control the seat to perform a second action according to the second current.

[0071] The body module 700 can be a module in the vehicle for sending a second adjustment signal to the seat module 500. Among them, the body module 700 can be a main controller, etc. The second adjustment signal can be a second adjustment signal generated by the body module 700 when the user actively adjusts the seat. For example, the user can send an instruction to the body module 700 through voice, touch screen, etc., and the body module 700 can generate a second adjustment signal in response to the instruction.

[0072] The seat module 500 is electrically connected to the seat back motor 600, which can be characterized as the seat module 500 being able to provide a second current to the seat back motor 600. Among them, the seat module 500 can receive the second adjustment signal, and then provide a second current to the seat back motor 600 according to the second adjustment signal. The seat back motor 600 controls the seat to perform a second action according to the second current. Among them, the second action can indicate controlling the seat to rotate (clockwise rotation or counterclockwise rotation), translate. For example, the seat back motor 600 controls the seat to rotate 30° clockwise according to the second current; for another example, the seat back motor 600 controls the seat to rotate 30° counterclockwise according to the second current.

[0073] It should be noted that the first action is the action performed by the seat when the vehicle is about to collide, and the second action is the action performed by the seat when the vehicle is in a normal situation (such as stationary, normal driving, etc.).

[0074] Optionally, the first current can be a preset multiple of the second current. Among them, the preset multiple can be 4 times, or 5 times, or 7 times, etc., and no specific limitation is made here.

[0075] In the seat quick return system provided in this embodiment, during the normal driving of the vehicle, the body module generates a second adjustment signal, so that after the seat module receives the second adjustment signal, it can provide a second current to the seat back motor, so that the seat back motor controls the seat to perform a second action according to the second current, so as to accurately adjust the seat during the normal driving of the vehicle.

[0076] In a possible implementation manner, the seat module 500 is further configured to stop providing the second current to the seat back motor 600 and send the first adjustment signal to the quick return activation module 300 when the seat back motor 600 controls the seat to perform a second action according to the second current and receives the first adjustment signal generated by the vehicle safety module 100.

[0077] The first adjustment signal generated by the vehicle safety module 100 can be sent to the seat module 500. Among them, when the vehicle is driving normally, the seat back motor 600 can control the seat to perform a second action according to the second current. During the process that the seat back motor 600 controls the seat to perform the second action according to the second current, if the seat module 500 receives the first adjustment signal, it indicates that the vehicle is about to collide, and the seat module 500 needs to stop providing the second current to the seat back motor 600 and send the first adjustment signal to the quick return activation module 300, so that the quick return activation module 300 sends the first current to the seat back motor 600, causing the seat to perform a quick return.

[0078] In the seat quick return system provided in this embodiment, the seat module needs to have the ability to judge the priority of multiple signals, determine that the priority of the first adjustment signal is greater than the priority of the second adjustment signal. During the process that the seat back motor controls the seat to perform the second action according to the second current, if the first adjustment signal is received, then stop providing the second current to the seat back motor, avoiding secondary injuries caused by the inertia or out-of-control of the seat.

[0079] Please refer to Figure 7 , Figure 7 which is a schematic structural diagram of another seat quick return system provided according to the embodiments of the present application.

[0080] In a possible implementation manner, the seat module 500 is connected to the quick return activation module 300; the vehicle body module 700 of the vehicle is used to generate a second adjustment signal for the seat; the vehicle's vehicle power supply 200 is further used to supply power to the seat module 500 through the wire harness for supplying power to the seat module 500; the seat module 500 is used to receive the second adjustment signal and send the second adjustment signal to the quick return activation module 300; the quick return activation module 300 is used to receive the second adjustment signal and provide the second current to the seat back motor 600 according to the second adjustment signal; the seat back motor 600 is further used to control the seat to perform a second action according to the second current.

[0081] In this embodiment, the seat module 500 and the quick return activation module 300 are communicatively connected, where the seat module 500 is used to send the first adjustment signal or the second adjustment signal to the quick return activation module 300. Specifically, the vehicle body module 700 of the vehicle can generate a second adjustment signal, and the second adjustment signal can be first sent to the seat module 500, and then the seat module 500 sends the second adjustment signal to the quick return activation module 300, so that the quick return activation module 300 sends the second current to the seat back motor 600 according to the second adjustment signal, causing the seat back motor 600 to control the seat to perform a second action according to the second current.

[0082] The seat quick return system provided in this embodiment is connected through a seat module and a quick return activation module. The seat module can receive a second adjustment signal and a first adjustment signal from the vehicle body module. The quick return activation module can generate a current according to the received second adjustment signal or first adjustment signal and supply it to the seat back motor, so that the functional responsibilities of the seat module and the quick return activation module are single, reducing the development complexity. Moreover, if the seat malfunctions, the problem can be quickly located by troubleshooting the seat module or the quick return activation module.

[0083] In a possible implementation manner, the seat module 500 is further configured to, when the seat back motor 600 controls the seat to perform a second action according to a second current and receives a first adjustment signal generated by the vehicle safety module 100, send the first adjustment signal to the quick return activation module 300; the quick return activation module 300 is further configured to, when receiving the first adjustment signal, determine the adjustment direction of the seat back, wherein when the adjustment direction of the seat back is counterclockwise, supply a first current to the seat back motor 600 according to the first adjustment signal of the seat, and when the adjustment direction of the seat back is clockwise, stop supplying the second current to the seat back motor 600 and supply a first current to the seat back motor 600 according to the first adjustment signal of the seat.

[0084] The first adjustment signal generated by the vehicle safety module 100 can be sent to the seat module 500, and the seat module 500 can send the first adjustment signal to the quick return activation module 300. When the vehicle is driving normally, the seat back motor 600 can control the seat to perform a second action according to a second current. During the process that the seat back motor 600 controls the seat to perform a second action, if the seat module 500 receives the first adjustment signal, it is necessary to further determine the adjustment direction of the seat back. Since the adjustment direction of the seat for the first action according to the first current is counterclockwise, if the adjustment direction of the seat back is counterclockwise, directly supply the first current to the seat back motor 600 to make the seat quickly return. If the adjustment direction of the seat back is clockwise, then it is necessary to stop supplying the second current to the seat back motor 600 and supply the first current to the seat back motor 600 according to the first adjustment signal of the seat, so as to avoid the opposite directions of the first current and the second current and reduce the efficiency of the seat quick return.

[0085] The seat quick return system provided in this embodiment can immediately send the first adjustment signal to the quick return activation module after the seat module receives the first adjustment signal sent by the vehicle safety module. The quick return activation module accurately controls the motor current by judging the adjustment direction of the backrest (clockwise or counterclockwise). When the adjustment direction of the seat backrest is counterclockwise, it directly provides the first current to the seat backrest motor, enabling the seat to quickly return. When the adjustment direction of the seat backrest is clockwise, it stops providing the second current to the seat backrest motor and provides the first current to the seat backrest motor according to the first adjustment signal of the seat, avoiding the opposite directions of the first current and the second current and reducing the efficiency of the seat quick return.

[0086] In a possible implementation, the quick return activation module 300 includes: a circuit board (not shown in the figure) and a target component (not shown in the figure); wherein, the target component includes any one of a capacitor and a lithium battery; the circuit board is communicatively connected to the vehicle safety module 100 for receiving the first adjustment signal; the vehicle's vehicle power supply 200 is also used to charge the target component; the target component is disposed on the circuit board and is used to provide the first current to the seat backrest motor 600 according to the first adjustment signal.

[0087] The circuit board can be communicatively connected to the vehicle safety module 100. Among them, the communication connection between the circuit board and the vehicle safety module 100 can be achieved through an electrical interface or a bus, so that the circuit board receives the first adjustment signal from the vehicle safety module 100.

[0088] The target component can be any one of a capacitor and a lithium battery; wherein, when the target component is a capacitor, the capacitor can be an energy storage component in the quick return activation module 300. The capacitor is configured on the circuit board for storing electrical energy and quickly releasing it when needed.

[0089] As an example, after the circuit board receives and processes the first adjustment signal, the circuit board can send the first adjustment signal to the capacitor. After receiving the first adjustment signal, the capacitor can quickly release the stored electrical energy to provide the required first current to the seat backrest motor 600.

[0090] Optionally, the capacitance of the capacitor is greater than 50 farads.

[0091] As an example, the capacitance value can be determined before the quick return activation module 300 is assembled in the vehicle. The specific determination method can be as follows: When the power of the seat back motor 600 is 720W, according to P = UI, the normal operating current of the seat back motor 600 can be calculated as 60A. In order to adjust the seat to a safe position within 0.5 - 0.7s before a vehicle collision, the starting current (I_start) of the seat back motor 600 can be 4 - 7 times the normal operating current, that is, I_start can be 420A; the charge Q required to activate the seat back motor 600 within 0.7s is Q = I_start * t = 420A * 0.7s = 294C; capacitance: C = charge Q / voltage U = 294C / 12V = 24.5F. Since a 2-fold safety capacity needs to be reserved, the capacitance value is greater than 50F.

[0092] When the target component is a lithium battery, the lithium battery can be the energy storage component in the quick return activation module 300. The lithium battery is configured on the circuit board to store electrical energy and release it quickly when needed. Specifically, when the circuit board receives and processes the first adjustment signal, it sends a first adjustment signal to the lithium battery. After receiving the first adjustment signal, the lithium battery quickly releases the stored electrical energy to provide the required first current for the seat back motor 600.

[0093] Optionally, the capacity of the lithium battery is greater than 0.2 ampere - hours.

[0094] As an example, the capacity of the lithium battery can be determined before the quick return activation module 300 is assembled in the vehicle. The specific determination method can be as follows: When the power of the seat back motor 600 is 720W, according to P = UI, the normal operating current of the seat back motor 600 can be calculated as 60A. In order to adjust the seat to a safe position within 0.5 - 0.7s before a vehicle collision, the starting current (I_start) of the seat back motor 600 can be 4 - 7 times the operating current, that is, I_start can be 420A; the charge Q required to activate the seat back motor 600 within 0.7s is Q = I_start * t = 420A * 0.7s = 294C; lithium battery: battery charge = 294C / 3600 ≈ 0.082Ah (ampere - hours). Since a 2-fold safety capacity needs to be reserved, the capacity of the lithium battery is greater than 0.2Ah.

[0095] In the seat quick return system provided in this embodiment, the circuit board, as the core component of the quick return activation module, establishes a stable communication connection with the vehicle safety module, enabling the first adjustment signal to be accurately and quickly sent to the circuit board. The circuit board sends the first adjustment signal to the capacitor. Since the capacitor has an energy storage function, the capacitor can quickly discharge after receiving the signal to provide the required first current for the seat back motor.

[0096] In addition, a lithium battery is disposed on the circuit board and serves as an energy source for the rapid seat return function. The lithium battery has a high energy density, a long service life, and stable discharge performance, so as to be able to supply a required first current to the seat back motor.

[0097] Please refer to Figure 8 , Figure 8 which is a schematic structural diagram of another seat rapid return system provided according to an embodiment of the present application.

[0098] In a possible implementation manner, as shown in Figure 8 , the system further includes: a first anti-backflow module 800 is located between the seat back motor 600 and the rapid return activation module 300, and is electrically connected to the seat back motor 600 and the rapid return activation module 300; a second anti-backflow module 900 is located between the seat module 500 and the seat back motor 600, and is electrically connected to the seat module 500 and the seat back motor 600.

[0099] The function of the anti-backflow module is to prevent current backflow and protect devices (such as capacitors) in the circuit from being damaged. The first anti-backflow module 800 can be located in the power supply circuit of the seat back motor 600 to prevent the backflow current generated when the motor is powered off or operates in reverse from damaging the circuit. At the same time, it may also be connected to the rapid return activation module 300 to ensure the safe operation of the seat back motor during the rapid return process. The second anti-backflow module 900 is located in the power supply circuit of the seat back motor 600 and can be connected to the seat module 500 to ensure that no current backflow occurs when the seat module 500 supplies a second current to the seat back motor 600.

[0100] For the seat rapid return system provided in this embodiment, anti-backflow modules are added both between the seat module and the seat back motor and between the rapid return activation module and the seat back motor, which can prevent current backflow when the seat module and the rapid activation module supply power to the seat back motor respectively, and avoid damage to the seat module and the rapid return activation module.

[0101] According to an embodiment of the present application, an embodiment of a seat rapid return method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0102] In this embodiment, a method for rapid seat return is provided, which can be used in a vehicle. The vehicle can be used to execute the method for rapid seat return. The vehicle includes a seat, a rapid return activation module, a wire harness box, a seat module, and a seat back motor; the rapid return activation module is electrically connected to the seat back motor, and the wire harness for supplying power to the rapid return activation module is electrically connected to the wire harness that passes through the wire harness box and supplies power to the seat module. Figure 9 It is a schematic flow chart of the method for rapid seat return provided by the embodiment of the present application, as Figure 9 shown. The process includes the following steps:

[0103] Step S901: Use the rapid return activation module to receive the first adjustment signal of the seat.

[0104] Step S902: Use the rapid return activation module to provide a first current to the seat back motor according to the first adjustment signal of the seat, so that the seat back motor controls the seat to perform a first action according to the first current.

[0105] The rapid return activation module can receive the first adjustment signal of the seat and provide a first current to the seat back motor according to the first adjustment signal of the seat, so that the seat back motor controls the seat to rapidly return according to the first current.

[0106] The first adjustment signal of the seat can be generated by the vehicle body controller of the vehicle or by the vehicle's overall vehicle safety module, and specific limitations are not made here.

[0107] As an example, the overall vehicle safety module can generate the first adjustment signal of the seat when the vehicle is about to collide.

[0108] The wire harness for supplying power to the rapid return activation module can be connected to the vehicle's overall vehicle power supply or to the vehicle's battery, etc. Correspondingly, when the wire harness for supplying power to the rapid return activation module is connected to the vehicle's overall vehicle power supply, the vehicle's overall vehicle power supply can supply power to the rapid return activation module through the wire harness for supplying power to the rapid return activation module; when the wire harness for supplying power to the rapid return activation module is connected to the vehicle's battery, the vehicle's battery can supply power to the rapid return activation module through the wire harness for supplying power to the rapid return activation module. The wire harness that passes through the wire harness box and supplies power to the seat module can be connected to the vehicle's overall vehicle power supply or to the vehicle's battery, etc.

[0109] The seat rapid return method provided in this embodiment is such that the rapid return activation module can quickly receive and process the first adjustment signal to generate a first current, and at the same time supply the first current to the seat back motor, enabling the seat back motor to control the seat to be adjusted to a safe position. Moreover, the wire harness that powers the rapid return activation module is electrically connected to the wire harness that passes through the wire harness box and powers the seat module, that is, the wire harness that powers the rapid return activation module is not arranged inside the wire harness box, so there is no need to add a large-current wire harness inside the wire harness box. On the one hand, it can improve the efficiency of adjusting the seat to an angle for protecting the safety of passengers, and on the other hand, it can reduce the diameter of the wire harness inside the wire harness box, thereby reducing the occupied area of the wire harness inside the wire harness box.

[0110] In a possible implementation manner, the above method further includes:

[0111] Step S903, if the power of the rapid return activation module is not greater than the preset power, use the vehicle's vehicle power supply to supply power to the rapid return activation module through the wire harness that supplies power to the rapid return activation module.

[0112] The power of the rapid return activation module can be used as a condition for whether the vehicle power supply supplies power to the rapid return activation module. Among them, the vehicle can be configured with a power detection module. The power detection module can detect the power of the rapid return activation module. When the power of the rapid return activation module is not greater than the preset power, it indicates that the power of the rapid return activation module is not sufficient to supply the first current to the seat back motor, and then the rapid return activation module needs to be powered.

[0113] In a possible implementation manner, the above method further includes:

[0114] Step S904, if the capacitance stored power of the capacitor of the rapid return activation module is not greater than the preset capacitance stored power, use the vehicle's vehicle power supply to supply power to the rapid return activation module through the wire harness that supplies power to the rapid return activation module.

[0115] The capacitance stored power of the capacitor of the rapid return activation module can be used as a condition for whether the vehicle power supply supplies power to the rapid return activation module. Among them, the vehicle can be configured with a capacitance stored power detection module. The capacitance stored power detection module can detect the capacitance stored power of the capacitor of the rapid return activation module. When the capacitance stored power of the capacitor of the rapid return activation module is not greater than the preset capacitance stored power, it indicates that the power of the rapid return activation module is not sufficient to supply the first current to the seat back motor, and then the rapid return activation module needs to be powered.

[0116] In a possible implementation manner, the seat module is electrically connected to the seat back motor; and the method further includes:

[0117] Step S905, use the seat module to receive the second adjustment signal of the seat.

[0118] The second adjustment signal of the seat can be generated by the main controller or by other controllers, and no specific limitation is made here. The second adjustment signal can be the second adjustment signal generated by the main controller when the user actively adjusts the seat. For example, the user can send an instruction to the main controller by means of voice, touching the screen, etc., and the main controller can generate a second adjustment signal in response to the instruction.

[0119] Step S906: Using the seat module, supply a second current to the seat back motor according to the second adjustment signal of the seat, so that the seat back motor controls the seat to perform a second action according to the second current; wherein, the first current is greater than the second current.

[0120] The second current can be the current generated after the seat module receives the second adjustment signal. The seat module can supply the second current to the seat back motor, so that the seat back motor controls the seat to perform a second action according to the second current; wherein, the first current is greater than the second current.

[0121] In a possible implementation manner, when the seat back motor controls the seat to perform a second action according to the second current and receives the first adjustment signal generated by the vehicle safety module, use the seat module to stop supplying the second current to the seat back motor and send the first adjustment signal to the quick return activation module.

[0122] In a possible implementation manner, the seat module is connected to the quick return activation module; and the method further includes:

[0123] Step S907: Use the quick return activation module to receive the second adjustment signal, where the second adjustment signal is sent by the seat module.

[0124] The seat module and the quick return activation module are communicatively connected. The function of the seat module is to send the second adjustment signal to the quick return activation module, that is, in this embodiment, the seat module does not send the second current to the seat back motor, and both the first current and the second current can be sent to the seat back motor by the quick return activation module.

[0125] Step S908: Using the quick return activation module, supply a second current to the seat back motor according to the second adjustment signal, so that the seat back motor controls the seat to perform a second action according to the second current.

[0126] After receiving the second adjustment signal, the quick return activation module can supply a second current to the seat back motor according to the second adjustment signal, so that the seat back motor controls the seat to perform a second action according to the second current.
