Description

Technical Field

[0001] This application belongs to the field of vehicle safety protection, specifically relating to a vehicle rear seat protection device, a control method for a vehicle rear seat protection device, a control device, an electronic device, and a computer-readable storage medium. Background Technology

[0002] Currently, passenger cars typically have a two- or three-seat layout in the rear, and in actual use, there are often one or more passengers in the rear. In the event of a side collision, although existing side airbags and side curtain airbags can provide effective protection for occupants on the side of the impact (i.e., the occupants closest to the impact), secondary collisions between rear occupants are difficult to avoid and may cause additional injuries.

[0003] In recent years, the industry's focus has gradually expanded from the safety protection of near-side occupants to the safety protection of occupants on the non-collision side (i.e., far-side occupants), and has begun to emphasize preventing mutual collision injuries between near-side and far-side occupants. Far-side protection has become an important indicator in automotive safety development.

[0004] However, the protection performance of rear-seat occupants at a distance is not currently included in the regulatory evaluation system, nor is it considered part of the passive safety performance development within the industry. Therefore, effectively protecting rear-seat occupants at a distance and preventing mutual collision injuries between them in side-impact accidents has become a pressing technical challenge that needs to be addressed. Summary of the Invention

[0005] This application aims to solve at least one of the technical problems existing in the prior art. To this end, this application proposes a rear-seat protection device for vehicles, its control method, and related equipment.

[0006] In a first aspect, embodiments of this application provide a vehicle rear seat protection device, comprising: The airbag mechanism is installed on the back of the target seat in the vehicle. The target seat has at least one adjacent side seat on both the left and right sides. When deployed, the airbag mechanism is used to separate the side seat on the left side of the target seat from the side seat on the right side of the target seat. The armrest mechanism is foldably mounted on the back of the target seat via a flipping mechanism. In the flipped state, the armrest mechanism is used to separate the side seat on the left side of the target seat from the side seat on the right side of the target seat. An angle sensor is installed on the handrail mechanism to detect the status of the handrail mechanism; A occupancy sensor is installed on the seat cushion of the target seat to detect whether the seat cushion is occupied.

[0007] In some embodiments, the flipping mechanism includes: The first fixed end is fixedly installed on the back of the target seat; The second fixed end is connected to the first end of the handrail mechanism; wherein the handrail mechanism rotates around the first end when it is rotated. A gas power device is located between the first fixed end and the second fixed end, and is connected to the first fixed end. The gas power device expands and generates thrust when it is inflated. The sliding power mechanism is located between the first fixed end and the second fixed end. It is connected to the second fixed end through a limiting spring. Under the thrust of the pneumatic power device, the sliding power mechanism pushes the second fixed end to pop out in a direction away from the first fixed end, so that the second fixed end drives the armrest mechanism to flip towards the seat cushion of the target seat, thus achieving the flipping state.

[0008] In some embodiments, the airbag mechanism is positioned higher than the armrest mechanism in the non-flipped state.

[0009] In some embodiments, the vehicle rear seat protection device further includes: A collision detection device is used to detect whether a target vehicle has been involved in a side collision.

[0010] According to an embodiment of this application, a vehicle rear-seat protection device, when a side collision occurs, if there is no occupant in the middle rear seat, the controller sends an ignition command to the airbag mechanism. Upon receiving the command, the airbag mechanism immediately inflates and deploys, simultaneously driving a tilting mechanism to tilt the armrest mechanism inwards, creating a barrier between the left and right rear occupants to prevent direct collision. The tilted armrest mechanism and the deployed airbag together form a support surface, suppressing abnormal twisting or movement of the occupant's torso and restoring them to a suitable posture, avoiding secondary injuries caused by large movements. This application provides effective protection for the rear far-end occupants in side collisions, significantly improving their protective performance.

[0011] Secondly, embodiments of this application provide a control method for a vehicle rear seat protection device, applied to a vehicle rear seat protection device, the method comprising: In response to a collision with the target vehicle, the occupancy sensor detects whether the seat cushion of the target seat is occupied. In response to the target seat not being occupied, the control airbag mechanism deploys and the armrest mechanism flips to separate the side seat on the left side of the target seat from the side seat on the right side of the target seat.

[0012] In some embodiments, controlling the airbag mechanism to deploy includes: The gas generator controlling the airbag mechanism is activated to rapidly inflate the airbag mechanism, causing it to deploy from the back of the target seat.

[0013] In some embodiments, controlling the armrest mechanism to tilt includes: The pneumatic power device controlling the flipping mechanism inflates and generates thrust, which pushes the second fixed end of the flipping mechanism to pop out in a direction away from the first fixed end of the flipping mechanism through the sliding power mechanism, so that the second fixed end drives the armrest mechanism to flip towards the seat cushion of the target seat, thus achieving the flipping state.

[0014] According to an embodiment of this application, a control method for a vehicle rear seat protection device allows for the following protection: When a side collision occurs, if there is no occupant in the middle rear seat, the controller sends an ignition command to the airbag mechanism. Upon receiving the command, the airbag mechanism immediately inflates and deploys, simultaneously driving a tilting mechanism to tilt the armrest mechanism inwards, creating a barrier between the left and right rear occupants to prevent direct collision. The tilted armrest mechanism and the deployed airbag together form a support surface, suppressing abnormal twisting or movement of the occupant's torso and restoring them to a suitable posture, avoiding secondary injuries caused by large movements. This application provides effective protection for the rear far-end occupants in side collisions, significantly improving their protective performance.

[0015] Thirdly, embodiments of this application provide a control device, including: a first response module, configured to detect whether the seat cushion of the target seat is occupied by a occupancy sensor in response to a collision of the target vehicle; The second response module is configured to, in response to the target seat not being occupied, control the airbag mechanism to deploy and the armrest mechanism to flip, thereby separating the side seat on the left side of the target seat from the side seat on the right side of the target seat.

[0016] According to an embodiment of this application, a control device for a vehicle rear seat protection system allows for the following protection: When a side collision occurs, if there is no occupant in the middle rear seat, the controller sends an ignition command to the airbag mechanism. Upon receiving the command, the airbag mechanism immediately inflates and deploys, simultaneously driving a tilting mechanism to tilt the armrest mechanism inwards, creating a barrier between the left and right rear occupants to prevent direct collision. The tilted armrest mechanism and the deployed airbag together form a support surface, suppressing abnormal twisting or movement of the occupant's torso and restoring them to a suitable posture, avoiding secondary injuries caused by large movements. This application provides effective protection for the rear far-end occupants in side collisions, significantly improving their protective performance.

[0017] Fourthly, embodiments of this application provide an electronic device, including: a processor and a memory, wherein the memory stores a program or instructions that can run on the processor, and when the program or instructions are executed by the processor, implement the steps of the control method for the vehicle rear seat protection device as described in the second aspect.

[0018] According to an embodiment of this application, a vehicle rear-seat protection device, when a side collision occurs, if there is no occupant in the middle rear seat, the controller sends an ignition command to the airbag mechanism. Upon receiving the command, the airbag mechanism immediately inflates and deploys, simultaneously driving a tilting mechanism to tilt the armrest mechanism inwards, creating a barrier between the left and right rear occupants to prevent direct collision. The tilted armrest mechanism and the deployed airbag together form a support surface, suppressing abnormal twisting or movement of the occupant's torso and restoring them to a suitable posture, avoiding secondary injuries caused by large movements. This application provides effective protection for the rear far-end occupants in side collisions, significantly improving their protective performance.

[0019] Fifthly, embodiments of this application provide a computer-readable storage medium storing a program or instructions that, when executed by a processor, implement the steps of the control method for the vehicle rear seat protection device as described in the second aspect.

Detailed Implementation

[0024] Embodiments of this application will now be described in more detail with reference to the accompanying drawings. While some embodiments of this application are shown in the drawings, it should be understood that this application can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this application. It should be understood that the drawings and embodiments of this application are for illustrative purposes only and are not intended to limit the scope of protection of this application.

[0025] It should be understood that the steps described in the method embodiments of this application may be performed in different orders and / or in parallel. Furthermore, the method embodiments may include additional steps and / or omit the steps shown. The scope of this application is not limited in this respect.

[0026] As described in the background section, current regulations and industry development do not cover the protection of rear-seat occupants at the far end, resulting in a lack of effective protection for occupants at the far end of a side collision. This application provides a rear-seat protection device: when a side collision occurs and there is no occupant in the middle rear seat, the controller sends an ignition command to the airbag mechanism, causing the airbag to inflate instantly; simultaneously, a tilting mechanism drives the armrest mechanism to tilt inwards, creating a barrier between the left and right rear occupants to prevent them from being crushed in a collision. The armrest mechanism and the airbag together form a stable support surface, suppressing abnormal torso twisting and correcting the occupant's posture, thus preventing secondary injuries. This solves the problem of the lack of an effective protection solution for secondary collision injuries to rear-seat occupants at the far end.

[0027] refer to Figure 1 This is a schematic diagram of the structure of a vehicle rear seat protection device in an embodiment of this application.

[0028] like Figure 1As shown, the vehicle rear seat protection device 100 includes: an airbag mechanism 1, which is disposed on the back of the target seat of the vehicle. The target seat has at least one adjacent side seat 2 on both the left and right sides. When deployed, the airbag mechanism 1 is used to separate the side seat 2 on the left side of the target seat from the side seat 2 on the right side of the target seat.

[0029] In practical implementation, this rear-seat protection device is suitable for vehicles equipped with a three-seat rear layout. In such vehicles, there is an adjacent side seat 2 on both the left and right sides of the middle seat, and its airbag mechanism 1 is built into the backrest of the middle rear seat. When a side collision occurs, the rear-seat protection device receives a trigger command from the controller via the CAN bus, causing the airbag to deploy rapidly. The deployed airbag effectively separates the occupant sitting on the left side seat from the occupant sitting on the right side seat, forming a physical buffer between the occupants on both sides. This significantly reduces the average impact force experienced by the occupants during a collision, thereby preventing injuries caused by mutual collisions between occupants.

[0030] The armrest mechanism 4 is rotatably mounted on the back of the target seat via the flipping mechanism 3. In the flipped state, the armrest mechanism 4 is used to separate the side seat 2 on the left side of the target seat from the side seat 2 on the right side of the target seat.

[0031] In practice, the armrest mechanism 4 is built into the backrest of the middle rear seat and can be flipped inwards. In the flipped state, the armrest mechanism 4 can effectively separate the occupants sitting on the left and right seats. It can not only provide elbow support for the occupants and help them maintain a relaxed and stable sitting posture, but also form a physical isolation between the occupants on the left and right sides, thus playing an effective limiting role.

[0032] An angle sensor 6 is installed on the handrail mechanism 4 to detect the state of the handrail mechanism 4.

[0033] The occupancy sensor 5 is installed on the seat cushion of the target seat to detect whether the seat cushion of the target seat is occupied.

[0034] In practice, the angle sensor 6 is installed on the handrail mechanism 4 to monitor the flipping angle of the handrail mechanism 4 in real time, and sends the real-time angle data to the controller via the CAN bus. The controller determines whether the handrail mechanism 4 is in the retracted state or the flipped state based on the received angle information.

[0035] The occupancy sensor 5 is located inside the seat cushion of the middle seat. It collects the pressure data of the seat cushion in real time and sends the data to the controller via the CAN bus. Based on the received pressure information, the controller accurately determines whether there is a passenger sitting in the middle seat.

[0036] refer to Figure 2This is a schematic diagram of the structure of the flipping mechanism 3 in the embodiment of this application.

[0037] like Figure 2 As shown, the flipping mechanism 3 includes: The first fixed end 201 is fixedly installed on the back of the target seat.

[0038] The second fixed end 205 is connected to the first end of the handrail mechanism 4; wherein the handrail mechanism 4 rotates around the first end when it is rotated.

[0039] The gas power device 202 is disposed between the first fixed end 201 and the second fixed end 205 and is connected to the first fixed end 201. The gas power device 202 expands and generates thrust when it is in the inflation state.

[0040] The sliding power mechanism 203 is located between the first fixed end 201 and the second fixed end 205. It is connected to the second fixed end 205 through the limiting spring 204. Under the thrust of the gas power device 202, the sliding power mechanism 203 pushes the second fixed end 205 to pop out in a direction away from the first fixed end 201, so that the second fixed end 205 drives the armrest mechanism 4 to flip towards the seat cushion of the target seat, thus achieving the flipping state.

[0041] In a specific implementation, the first fixed end 201 is fixed inside the backrest of the middle seat; the gas power device 202, consisting of an airbag controller and an airbag, is arranged between the first fixed end 201 and the second fixed end 205 and is rigidly connected to the first fixed end 201; the sliding power mechanism 203 is also located between the first fixed end 201 and the second fixed end 205 and is connected to the second fixed end 205 through a limiting spring 204; the second fixed end 205 is connected to the first end of the armrest mechanism 4, which is the contact end between the armrest mechanism 4 and the flipping mechanism 3.

[0042] In the event of a side collision, if the armrest mechanism 4 is in the retracted state and there is no occupant in the middle seat, the controller sends an ignition signal to the airbag controller in the gas power unit 202 via the CAN bus. Upon receiving the signal, the airbag controller immediately inflates the airbag, causing it to expand instantaneously. This inflates the sliding power mechanism 203 with a thrust directed towards the interior of the vehicle. This thrust overcomes the preload of the limiting spring 204 and drives the second fixed end 205 to pop out in a direction away from the first fixed end 201, i.e., pop out into the vehicle. This, in turn, causes the armrest mechanism 4 to flip towards the target seat cushion until it reaches a horizontally unfolded state.

[0043] Optionally, the airbag mechanism 1 is positioned higher than the armrest mechanism 4 in the non-flipped state.

[0044] In practice, the airbag mechanism 1 is generally located above the armrest mechanism 4 in the non-flipped state. When the vehicle is involved in a side collision, the airbag mechanism 1 can act synchronously with the flipping mechanism 3.

[0045] Optionally, the rear seat protection device 100 also includes: A collision detection device is used to detect whether a target vehicle has been involved in a side collision.

[0046] In practice, the collision detection device is installed on the side of the vehicle and sends door pressure signals and lateral acceleration signals to the controller in real time via the CAN bus. When the controller detects a sharp increase in door pressure and a sudden change in lateral acceleration, it determines that the vehicle has been involved in a side collision.

[0047] In summary, according to the vehicle rear seat protection device proposed in this application, when a side collision occurs and there is no occupant in the middle rear seat, the controller sends an ignition command to the airbag mechanism, and the airbag inflates and deploys instantly. Simultaneously, the drive mechanism rotates the armrest mechanism inwards, creating a barrier between the left and right rear occupants to prevent them from colliding and being crushed. The armrest mechanism and the airbag together form a stable support surface, suppressing abnormal torso twisting and correcting the occupant's posture, thus avoiding secondary injuries. This provides remote protection for rear occupants in side collision accidents, comprehensively improving the side collision protection performance of rear occupants.

[0048] Corresponding to the above embodiments, the present invention also proposes a control method for a vehicle rear seat protection device.

[0049] refer to Figure 3 This is a flowchart illustrating a control method for a vehicle rear seat protection device according to an embodiment of this application.

[0050] like Figure 3 As shown, the control method for the vehicle's rear seat protection device includes: In step S301, in response to a collision with the target vehicle, the occupancy sensor 5 detects whether the seat cushion of the target seat is occupied.

[0051] In step S302, in response to the target seat not being occupied, the airbag mechanism 1 is deployed and the armrest mechanism 4 is flipped to separate the side seat 2 on the left side of the target seat from the side seat 2 on the right side of the target seat.

[0052] refer to Figure 4 This is a control flowchart in an embodiment of this application when the airbag mechanism 1 is positioned above the armrest mechanism 4.

[0053] Specifically, such as Figure 4As shown, during vehicle operation, the collision detection device continuously collects real-time data and sends it to the controller via the CAN bus. The controller analyzes the data based on its built-in algorithm. When a side collision is detected, it immediately calls the pressure data returned by the occupancy sensor 5 to detect whether there is an occupant in the middle rear seat. If there is an occupant, the controller prevents the airbag mechanism 1 and the tilting mechanism 3 from performing any actions. If there is no occupant, the controller further reads the angle value of the armrest mechanism 4 returned by the angle sensor 6 to determine the current position of the armrest. If the armrest mechanism 4 is already in the tilted state, the controller does not send a command to the tilting mechanism 3 and maintains the status quo. If the armrest mechanism 4 is in the retracted state, the controller immediately sends an ignition command to the tilting mechanism 3, causing the gas power unit 202 inside the tilting mechanism 3 to ignite, driving the tilting mechanism 3 to move and causing the armrest mechanism 4 to complete the tilting. At the same time, the controller also sends an ignition signal to the gas generator inside the airbag mechanism 1, causing the airbag mechanism 1 to deploy.

[0054] refer to Figure 5 This is a control flowchart for the position of the airbag mechanism 1 coinciding with the armrest mechanism 4 in the embodiments of this application.

[0055] Specifically, such as Figure 5 As shown, during vehicle operation, the collision detection device continuously collects real-time data and sends it to the controller via the CAN bus. The controller analyzes the data based on its built-in algorithm. When a side collision is detected, it immediately calls the pressure data returned by the occupancy sensor 5 to detect whether there is an occupant in the middle rear seat. If there is an occupant, the controller prevents the airbag mechanism 1 and the tilting mechanism 3 from performing any actions. If there is no occupant, the controller further reads the angle value of the armrest mechanism 4 returned by the angle sensor 6 to determine the current position of the armrest. If the armrest mechanism 4 is already in the tilted state, the controller maintains its current state. If the armrest mechanism 4 is in the retracted state, the controller immediately sends an ignition command to the tilting mechanism 3. The gas power device 202 inside the tilting mechanism 3 is ignited, driving the tilting mechanism 3 to move and causing the armrest mechanism 4 to complete the tilting. After the armrest mechanism 4 reaches the tilted state, the controller sends an ignition signal to the gas generator inside the airbag mechanism 1, causing the airbag mechanism 1 to deploy.

[0056] In some embodiments, controlling the deployment of the airbag mechanism 1 includes: The gas generator of the airbag mechanism 1 is activated to rapidly inflate the airbag mechanism 1 so that the airbag mechanism 1 can be ejected from the back of the target seat.

[0057] In some embodiments, controlling the armrest mechanism 4 to flip includes: The gas power device 202 of the control flipping mechanism 3 is inflated and generates thrust, so as to push the second fixed end 205 of the flipping mechanism 3 to pop out in a direction away from the first fixed end 201 of the flipping mechanism 3 through the sliding power mechanism 203, so that the second fixed end 205 drives the armrest mechanism 4 to flip towards the seat cushion of the target seat, thus achieving the flipping state.

[0058] Specifically, after the controller issues an ignition command, it sends an electrical pulse signal to the gas generator, triggering its built-in igniter. The igniter ignites the gas-generating agent, which burns instantly to generate a high-speed airflow. This airflow rushes into the folding airbag, causing it to inflate and eject from the target seat back, completing the deployment. Simultaneously, the controller issues an ignition command to the gas power unit 202 of the flipping mechanism 3. The unit inflates and compresses the sliding power mechanism 203, generating a thrust pointing inwards. This thrust overcomes the preload of the limiting spring 204, pushing the second fixed end 205 outwards in a direction away from the first fixed end 201, causing the armrest mechanism 4 to flip towards the seat cushion to a horizontally unfolded state.

[0059] In summary, according to the control method for a vehicle rear seat protection device proposed in this application, when a side collision occurs and there is no occupant in the middle rear seat, the controller sends an ignition command to the airbag mechanism, and the airbag inflates and deploys instantly. Simultaneously, the drive mechanism rotates the armrest mechanism inwards, creating a barrier between the left and right rear occupants to prevent them from colliding and being crushed. The armrest mechanism and the airbag together form a stable support surface, suppressing abnormal torso twisting and correcting the occupant's posture, thus avoiding secondary injuries. This provides remote protection for rear occupants in side collision accidents, comprehensively improving the side collision protection performance of rear occupants.

[0060] It should be noted that the method of this embodiment can be executed by a single device, such as a computer or server. The method of this embodiment can also be applied to a distributed scenario, where multiple devices cooperate to complete the task. In such a distributed scenario, one of these devices may execute only one or more steps of the method of this embodiment, and the multiple devices will interact with each other to complete the above method.

[0061] It should be noted that the above description describes some embodiments of the present invention. Other embodiments are within the scope of the appended claims.

Furthermore, the processes depicted in the drawings do not necessarily require a specific or sequential order to achieve the desired results.

[0062] Corresponding to the above embodiments, the present invention also proposes a control device.

[0063] refer to Figure 6 This is a schematic diagram of the control device in an embodiment of the present invention.

[0064] This application provides a control device 600 for a vehicle rear seat protection device, including: The first response module 601 is configured to detect whether the seat cushion of the target seat is occupied by a occupancy sensor in response to a collision with the target vehicle.

[0065] The second response module 602 is configured to, in response to the target seat not being occupied, control the airbag mechanism to deploy and the armrest mechanism to flip, thereby separating the side seat on the left side of the target seat from the side seat on the right side of the target seat.

[0066] Optionally, the second response module 602 is also configured to: The gas generator controlling the airbag mechanism is activated to rapidly inflate the airbag mechanism, causing it to deploy from the back of the target seat.

[0067] Optionally, the second response module 602 is also configured to: The pneumatic power unit controlling the flipping mechanism inflates and generates thrust, which pushes the second fixed end of the flipping mechanism away from the first fixed end via a sliding power mechanism.
