Technical Field

[0001] This application belongs to the field of seat adjustment technology, specifically relating to a seat and its adjustment method, a vehicle, and a storage medium. Background Technology

[0002] Currently, car seats on the market offer increasingly sophisticated features. Not only driver's seats can slide forward and backward and adjust their backrest angle, but second and third-row seats also possess these adjustment functions, and even zero-gravity seats have emerged, with backrests that can be completely reclined. However, when front-row passengers adjust their seats, there is an unavoidable risk of compression on rear-row passengers and belongings. This risk is particularly pronounced when children are seated in both the second and third rows, and could even lead to serious accidents where children are crushed and killed during seat adjustments.

[0007] In some embodiments, the seat body further includes a seat cushion and a base; The drive assembly includes a first drive member and a second drive member. The first drive member drives the backrest to rotate, and the second drive member drives the seat cushion to rotate and / or move. Both the first drive member and the second drive member are electrically connected to the controller. When the pressure sensor detects that the pressure of the airbag is greater than or equal to a first preset value, the controller controls the currently operating first drive unit and / or second drive unit to stop working.

[0008] In some embodiments, a pressure control component is also included, which is in communication with the airbag and electrically connected to the controller; Upon receiving a seat adjustment command, the air pressure control component inflates the airbag to give it an initial air pressure value.

[0009] The technical solution adopted to achieve the purpose of this application is as follows: In the second aspect of this application, the present invention also discloses a method for adjusting a seat based on the first aspect described above, comprising the following steps: In response to a seat adjustment command, the control drive assembly drives the seat body to move; The airbag pressure detected by the pressure sensor is obtained. During the operation of the drive assembly driving the seat body to move, if the received airbag pressure is greater than or equal to a first preset value, the drive assembly is controlled to stop the current operation so that the seat stops moving.

[0010] In some embodiments, when the airbag pressure is greater than or equal to a first preset value, the adjustment method further includes: The drive assembly is controlled to drive the seat body to move in the opposite direction.

[0011] In some embodiments, controlling the drive assembly to drive the seat body to move in the opposite direction specifically includes: controlling the drive assembly to drive the seat body to move in the opposite direction until the pressure of the airbag is less than or equal to a second preset value; The second preset value is less than the first preset value, and the second preset value is greater than or equal to the initial air pressure value of the airbag.

[0012] In some embodiments, the control method in response to a seat adjustment command further includes: Control the inflation of the airbag to bring the airbag pressure to the initial air pressure value; After the seat body stops its current movement, the airbag is deflated.

[0013] The technical solution adopted to achieve the purpose of this application is as follows: In the third aspect of this application, the present invention also discloses a vehicle, which includes a vehicle body and the seat described in the first aspect above, wherein the seat body is installed inside the vehicle body.

[0014] The technical solution adopted to achieve the purpose of this application is as follows: In the fourth aspect of this application, the present invention also discloses a vehicle, including a processor and a memory, wherein the memory stores computer program instructions that can be executed by the processor, and when the processor executes the computer program instructions, it implements the operation performed by the control method described in the second aspect above.

The seat body includes a backrest. The drive assembly is used to drive the seat body to move. The airbag is installed on the rear side of the backrest. The pressure sensor is used to detect the pressure of the airbag. The controller is electrically connected to both the pressure sensor and the drive assembly. When the pressure sensor detects that the pressure of the airbag is greater than or equal to a first preset value, the controller controls the drive assembly to stop its current operation so that the seat stops its current movement.

[0017] The seat disclosed in this application has an airbag installed on the backrest side and equipped with a pressure sensor. When the backrest rotates backward, if the airbag is compressed by rear-seat objects or occupants, the pressure sensor can detect changes in airbag pressure in real time.

[0021] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this application. Such repetition is for simplification and clarity purposes and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials; however, those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0024] This invention discloses a seat that can solve the technical problem in the prior art where seat adjustment poses a risk of squeezing rear passengers and items.

[0025] The technical solution of this application will be described in detail below through specific embodiments: See Figure 1 In a first aspect embodiment of this application, a seat is disclosed, comprising a seat body 100, a drive assembly, an airbag 200, a pressure sensor, and a controller 300. The seat body 100 includes a backrest 110. The drive assembly drives the seat body 100 to move. The airbag 200 is mounted on the rear side of the backrest 110. The pressure sensor detects the pressure of the airbag 200. The controller 300 is electrically connected to both the pressure sensor and the drive assembly. During the operation of the drive assembly driving the seat body 100 to move, when the pressure sensor detects that the pressure of the airbag 200 is greater than or equal to a first preset value, the controller 300 controls the drive assembly to stop its current operation, thereby stopping the seat's current movement.

[0026] The seat disclosed in this embodiment has an airbag 200 installed on the rear side of the backrest 110, and is equipped with a pressure sensor. When the backrest 110 rotates backward, if the airbag 200 is compressed by a rear-seat object or occupant, the pressure sensor can detect changes in the airbag 200 pressure in real time. When the pressure reaches or exceeds a first preset value, the controller 300 will respond quickly and immediately control the backrest 110 to stop rotating backward. This mechanism can promptly interrupt actions that may cause compression injuries, greatly reducing the probability of compression accidents during seat adjustment and providing reliable safety protection for vehicle occupants.

[0027] In one embodiment, the airbag 200 is sheet-shaped when inflated. The airbag 200 includes a first side and a second side disposed opposite to each other. The first side fits against the backrest 110, and the second side faces outward relative to the backrest 110.

[0028] The airbag 200 inflates into a sheet shape with its second side facing outwards. This large surface area design allows it to cover a wider area behind the backrest 110. When the seat is adjusted, regardless of the direction from which an object approaches the backrest 110, there is a greater probability that it will come into contact with the airbag 200, thus triggering pressure detection. Compared to traditional small-area direct sensor placement, this sheet-shaped airbag 200 greatly expands the sensor's detection range, reduces blind spots, and enables more comprehensive monitoring of potential compression situations.

[0029] In real-world usage scenarios, there may be objects of various shapes and sizes behind the backrest 110, such as rear passengers of different sizes and luggage of various shapes. The larger surface area of ​​the sheet-like airbag 200 can better adapt to contact with these different objects. Regardless of whether the object is flat, curved, or irregularly shaped, it can generate sufficient contact area with the airbag 200, thus being detected by the pressure sensor, improving the seat's adaptability to detecting different objects behind it.

[0030] Because the airbag 200 has a large surface area, during seat movement, if an object behind the seat has approached to a certain distance before direct contact with the backrest 110, it may first make slight contact with or tend to compress the airbag 200. At this time, the pressure sensor can detect the slight change in airbag 200 pressure in time, sensing the potential compression situation in advance, rather than waiting until the object behind the seat is in full contact with the backrest 110 and generates significant pressure before reacting. This early detection capability allows the seat to take measures to stop movement more quickly, effectively shortening the time interval from detecting compression to taking action, and improving the timeliness of safety protection.

[0031] In one embodiment, along a direction perpendicular to the backrest 110, the overlapping area of ​​the projection of the second surface with the backrest 110 is 0.5 to 1 times the area of ​​the backrest 110.

[0032] When the overlap area reaches 0.5-1 times the area of ​​the backrest 110, the second surface of the airbag 200 covers a large area behind the backrest 110. This means that during seat adjustment, regardless of the position from which an object approaches the backrest 110, there is a high probability of it contacting the airbag 200, thus triggering pressure detection. Compared to a design with a small overlap area, this range effectively reduces detection blind spots, ensuring that the pressure sensor can promptly capture the compression between the object behind and the backrest 110, improving the comprehensiveness and reliability of the detection.

[0033] The larger overlapping area allows the airbags 200 to be more evenly distributed behind the backrest 110. When an object behind compresses the airbag 200, the pressure can be transmitted relatively evenly to all parts of the airbag 200, and thus accurately sensed by the pressure sensor. This uniform pressure sensing helps avoid detection errors caused by concentrated or uneven pressure distribution, enabling the controller 300 to make reasonable control decisions based on more accurate pressure information, ensuring the safety of the seat adjustment process.

[0034] In one embodiment, the seat body 100 further includes a seat cushion 120 and a base, with the backrest 110 rotatably connected to the seat cushion 120 and the seat cushion 120 rotatably and / or slidably connected to the base. The drive assembly includes a first drive member and a second drive member. The first drive member drives the backrest 110 to rotate, and the second drive member drives the seat cushion 120 to rotate and / or move, and both the first and second drive members are electrically connected to the controller 300.

[0035] When the pressure sensor detects that the pressure of the airbag 200 is greater than or equal to the first preset value, the controller 300 controls the currently operating first drive unit and / or second drive unit to stop working.

[0036] Whether the seat is being adjusted by rotating the backrest 110 degrees, rotating or moving the seat cushion 120 degrees, or both at the same time, it can stop the corresponding action in time as soon as a risk of squeezing is detected from behind, providing all-round safety protection for rear passengers or items.

[0037] During seat adjustment, immediately stopping all possible drive actions upon detecting pressure could cause unnecessary inconvenience to the user. For example, a user might only be briefly near an object in the rear seat to perform some operations and does not want the seat adjustment to stop. Setting a first preset value provides a broader stopping limit for the current task, rather than blindly stopping all drives, ensuring safety while minimizing interference with the user's normal operation. When the user adjusts a single component (such as adjusting only the backrest 110 or only the seat cushion 120), only the drive components related to that adjustment will stop; other non-dangerous adjustment functions can continue to be used, improving the convenience and comfort of using the seat.

[0038] In one embodiment, the seat further includes a pneumatic control assembly 400. The pneumatic control assembly 400 is in communication with the airbag 200 and is electrically connected to the controller 300.

[0039] Upon receiving a seat adjustment command, the air pressure control component 400 inflates the airbag 200 to give the airbag 200 an initial air pressure value.

[0040] After acquiring an initial air pressure value, the airbag 200 becomes more stable in shape and state, providing a relatively stable detection benchmark for the pressure sensor. When an object behind it comes into contact with the airbag 200 and causes a pressure change, the pressure sensor can detect this change more accurately, reducing detection errors caused by the instability of the airbag 200's initial state. For example, if the airbag 200 does not have initial air pressure, it may undergo significant deformation under slight pressure, causing large fluctuations in the pressure sensor's detection value. However, with initial air pressure, the deformation of the airbag 200 is more uniform and controllable, allowing the pressure sensor to more accurately capture the pressure change trend, thus improving the accuracy and reliability of the detection.

[0041] The air pressure control component 400 is electrically connected to the controller 300 and can precisely control the inflation process of the airbag 200 according to the instructions of the controller 300. Simultaneously, the controller 300 can also coordinate with other components of the seat, such as the drive assembly and pressure sensors. For example, when the controller 300 receives a seat adjustment command, it can simultaneously control the air pressure control component 400 to inflate the airbag 200 and activate the drive assembly to adjust the seat; when the pressure sensor detects an abnormal pressure in the airbag 200, the controller 300 can promptly stop the drive assembly from operating.

[0042] The pneumatic control component 400 is a mature technology, and this embodiment does not propose any improvements to the pneumatic control component 400 itself. Therefore, this embodiment will not further explain the structure and working principle of the pneumatic control component 400. The pneumatic control component 400 can be purchased and used directly on the market.

[0043] In one embodiment, a pressure relief valve is provided on the airbag 200. When the pressure inside the airbag 200 is greater than or equal to a third preset value, the airbag 200 releases pressure through the pressure relief valve. The third preset value is greater than or equal to a first preset value.

[0044] When an object behind the seat comes into contact with the airbag 200 during seat adjustment, and the pressure sensor detects that the pressure has reached the first preset value, the controller 300 will control the drive assembly to stop working to avoid compression. However, in some special circumstances, such as a sudden large external force applied by the object behind the seat or a brief delay in system response, the pressure inside the airbag 200 may continue to rise. In this case, the pressure relief valve opens to release pressure when the pressure reaches the third preset value (the third preset value is greater than or equal to the first preset value), which can prevent the airbag 200 from generating excessive compressive reaction force on the object behind the seat or the backrest 110 due to excessive pressure, avoiding more serious injury and providing dual safety protection for seat use.

[0045] Airbag 200 is typically made of a specific elastic material. When the internal pressure is too high, it may exceed the material's tolerance limit, leading to damage such as rupture, deformation, or loss of elasticity. A pressure relief valve is installed to release gas promptly when the airbag 200 pressure reaches a dangerous level, reducing the internal pressure, protecting the structural integrity of the airbag 200, and extending its service life.

[0046] The airbag 200 is inflated. After inflation is complete, the controller 300 obtains the initial air pressure value of the airbag 200. During the process of the first drive structure driving the backrest 110 to rotate backward, when the pressure sensor detects that the pressure of the airbag 200 is greater than or equal to the first preset value, the controller 300 controls the first drive structure to work in reverse to drive the backrest 110 to rotate upward until the pressure of the airbag 200 is less than or equal to the second preset value. During the process of the second drive structure driving the seat cushion 120 to move backward, when the pressure sensor detects that the pressure of the airbag 200 is greater than or equal to the first preset value, the controller 300 controls the second drive structure to work in reverse to drive the seat cushion 120 to move forward until the pressure of the airbag 200 is less than or equal to the second preset value.

[0047] The second drive structure can either drive the seat cushion 120 to rotate backward relative to the base, or it can move backward relative to the seat cushion 120.

[0048] Through the above embodiments, this application has the following beneficial effects or advantages: The seat disclosed in this application has an airbag 200 installed on the rear side of the backrest 110 and is equipped with a pressure sensor. When the backrest 110 rotates backward, if the airbag 200 is squeezed by a rear-seat object or occupant, the pressure sensor can detect the change in airbag 200 pressure in real time. When the pressure reaches or exceeds a first preset value, the controller 300 will respond quickly and immediately control the backrest 110 to stop rotating backward. This can interrupt actions that may cause squeezing injuries in time, greatly reducing the probability of squeezing accidents during seat adjustment, and providing reliable safety protection for occupants, especially for children who are more vulnerable, effectively avoiding squeezing injuries or even death caused by seat adjustment. When the airbag 200 pressure is detected to reach or exceed the first preset value, the control drive component drives the seat body 100 to move in the opposite direction until the airbag 200 pressure is less than or equal to a second preset value (the second preset value is less than the first preset value and greater than or equal to the initial air pressure value of the airbag 200). This reverse motion mechanism can further alleviate the existing compression situation, maintain a safe distance between the seat and rear objects or occupants, and further improve the safety during seat adjustment.

[0049] Upon receiving a seat adjustment command, the air pressure control component 400 inflates the airbag 200 to provide it with an initial air pressure value. After the seat body 100 stops its current movement, the airbag 200 is deflated. This design ensures that the airbag 200 can accurately sense pressure changes and trigger the safety protection mechanism in a timely manner during seat adjustment, while also preventing the airbag 200 from being inflated for extended periods, which could negatively impact seat space and comfort.

[0050] The technical solution adopted to achieve the purpose of this application is to disclose a seat adjustment method. This method is implemented based on the seat of any embodiment of the first aspect described above. For example, the adjustment method can be applied to the main control board of the seat in the above embodiments of this application, or to the vehicle controller 300 of the vehicle on which the seat of the above embodiments is mounted. In other embodiments, the adjustment method can also be executed by other devices that communicate data with the vehicle controller 300, such as remote control via mobile phones, computers, tablets, etc. This application does not limit the implementation methods of other devices or the execution entities of each embodiment.

[0051] See Figure 2 In a second aspect of this application, the present invention discloses a method for adjusting a seat based on the first aspect described above, comprising the following steps: In response to a seat adjustment command, the controller 300 controls the drive assembly to drive the seat body 100 to move. The controller 300 acquires the pressure of the airbag 200 detected by the pressure sensor. During the operation of the drive assembly driving the seat body 300 to move, when the pressure of the airbag 200 received by the controller 300 is greater than or equal to the first preset value, the controller 300 controls the drive assembly to stop the current operation so that the seat stops the current movement.

[0052] In the seat adjustment method disclosed in this embodiment, when the pressure sensor detects that the pressure of the airbag 200 reaches or exceeds a first preset value during seat adjustment, the controller 300 immediately controls the drive assembly to stop the current operation, thus stopping the seat's movement. This mechanism can promptly prevent the seat from continuing to move towards areas where people or objects may be present, avoiding crush injuries to rear passengers or items placed behind the seat due to seat adjustment, and providing reliable safety protection for people and items in seat usage scenarios. See Figure 3 In one embodiment, when the pressure of the airbag 200 is greater than or equal to a first preset value, the adjustment method further includes: The controller 300 controls the drive assembly to drive the seat body 100 to move in the opposite direction.

[0053] When the pressure of the airbag 200 reaches or exceeds the first preset value, it indicates that the seat adjustment process may have caused compression to objects or people behind. At this time, driving the seat body 100 to move in the opposite direction can immediately reduce the pressure on the compressed object and provide additional safety buffer space for the compressed object.

[0054] In some situations, even after the seat stops moving, the object being crushed may still be in a relatively dangerous state. For example, if there are fragile items behind the seat, these items may become unstable due to the previous compression after the seat stops. Reversing the movement can maintain a safer distance between the seat and the crushed object.

[0055] By setting a specific second preset value as the termination condition for reverse movement, the adjustment method can precisely control the degree of seat reverse movement. Unlike fuzzy control that stops only when the pressure reaches a first preset value, this precise pressure control method can adjust the airbag 200 pressure to the most suitable level according to different usage scenarios and safety requirements, ensuring that the seat adjustment will not fail to effectively relieve rear pressure due to insufficient movement, nor will it affect the comfort of passengers in the front seats due to excessive movement.

[0056] In one embodiment, controlling the drive assembly to drive the seat body 100 to move in the opposite direction specifically includes: the controller 300 controlling the drive assembly to drive the seat body 100 to move in the opposite direction until the pressure of the airbag 200 is less than or equal to a second preset value. The second preset value is less than the first preset value, and the second preset value is greater than or equal to the initial air pressure value of the airbag 200.

[0057] The system stops moving only when the airbag 200 pressure reaches the first preset value, which may result in a situation where the pressure, although not continuing to rise, remains at a relatively high dangerous level. Reversing the movement until the pressure is less than or equal to the second preset value reduces the pressure to a relatively safer range, significantly decreasing the possibility of residual potential danger. For example, if a precision instrument is placed in front of the seat, reversing the movement to the pressure state corresponding to the second preset value can better protect the instrument from potential damage caused by incomplete elimination of seat pressure.

[0058] In one embodiment, in response to a seat adjustment command, the control method further includes: The controller 300 controls the airbag 200 to inflate so that the airbag 200 pressure reaches the initial air pressure value; After the seat body 100 stops its current movement, the controller 300 controls the airbag 200 to deflate.

[0059] If the airbag 200 remains inflated during seat adjustment, it will occupy some space behind the seat, restricting the movement of people or objects behind it. Deflating the airbag 200 after the seat stops moving releases the occupied space, providing a more spacious area for people behind. This is especially beneficial in compact environments such as the back of a car or a small conference room, significantly improving the practicality and comfort of the space.

[0060] Furthermore, if the airbag 200 remains inflated during seat adjustment, it may become a rigid obstacle in the event of a collision or impact behind the seat, increasing the risk of injury to people or objects behind it. However, when the seat stops moving, the airbag 200 deflates, softening and providing some cushioning during a collision, absorbing some of the impact force and reducing the severity of injury to those behind it.

[0061] In some cases, such as when the second preset value is slightly greater than the initial air pressure of the airbag 200, the airbag 200 can be depressurized to achieve the same purpose of separating the airbag 200 from the passengers or objects behind it, thus making full use of the space.

[0062] See Figure 4 In one embodiment, the adjustment method further includes the following steps: When the pressure of the airbag 200 is greater than or equal to the third preset value, the pressure relief valve releases the pressure of the airbag 200.

[0063] When there is a brief delay in system response, the pressure in airbag 200 may continue to rise and reach a dangerous level, causing crush injuries to people or objects behind the seat. The pressure relief valve automatically opens to release pressure when the pressure in airbag 200 is greater than or equal to a third preset value, which can quickly reduce the pressure inside airbag 200, alleviate the crushing danger in time, and avoid injury to people or damage to objects due to excessive pressure.

[0064] This pressure relief mechanism provides an additional layer of safety for the seat adjustment system. Even if other safety measures fail to function in time due to system delays or other reasons, the pressure relief valve can activate at critical moments to ensure that the airbag 200 pressure does not rise indefinitely, thereby protecting the safety of the area behind the seat. This multi-layered safety design enhances the overall safety and reliability of the system.

[0065] The technical solution adopted to achieve the purpose of this application is as follows: In the third aspect of this application, the present invention also discloses a vehicle, which includes a vehicle body and a seat as described in the first aspect, wherein the seat body 100 is installed inside the vehicle body.

[0066] This means that one seat in the vehicle can be configured as the seat of the first aspect of this application, or all seats in the vehicle can be configured as the seat of the first aspect of this application. For example, if the vehicle is a normal sedan, the seat of the first aspect of this application can be configured in the driver's seat and the front passenger seat; if the vehicle is an MPV, the seat of the first aspect of this application can be configured in the driver's seat, the front passenger seat, and the second row of seats.

[0067] In traditional vehicles, the movement of the front seats during adjustment can cause crush injuries to rear passengers, especially children, potentially endangering their lives. However, the vehicle in this application is equipped with an airbag 200 installed on the rear side of the backrest 110, along with a pressure sensor and controller 300. When the backrest 110 rotates backward and presses against rear objects or passengers, the pressure sensor detects changes in the airbag 200 pressure in real time. Once the pressure reaches or exceeds a first preset value, the controller 300 immediately stops the backrest 110 from rotating. This mechanism promptly interrupts actions that could cause crush injuries, significantly reducing the probability of crush accidents during seat adjustment and providing reliable safety for vehicle occupants.

[0068] After the seat stops moving, the airbag 200 deflates promptly, preventing it from taking up too much space and providing passengers with more legroom and room to move. This increased space is especially beneficial when there are many rear passengers, making them feel more comfortable and less cramped. For example, during family trips, rear passengers can stretch their legs more freely, enhancing their overall riding experience.

[0069] The technical solution adopted to achieve the purpose of this application is as follows: In the fourth aspect of this application, the present invention also discloses a vehicle, including a processor and a memory, wherein the memory stores computer program instructions that can be executed by the processor, and when the processor executes the computer program instructions, it implements the operation performed by the control method of the second aspect described above.

[0070] The technical solution adopted to achieve the purpose of this application is as follows: In the fifth aspect of this application, the present invention also discloses a computer-readable storage medium, in which at least one piece of program code is stored, and the at least one piece of program code is loaded and executed by a processor to implement the operation performed by the control method of the second aspect above.

[0071] The functions described herein may be implemented in hardware, software executed by a processor, firmware, or any combination thereof. If implemented in software executed by a processor, the functions may be stored as one or more instructions or code on or transmitted via a computer-readable medium. Other examples and embodiments are within the scope and spirit of this application and the appended claims. For example, due to the nature of software, the functions described above may be implemented using software executed by a processor, hardware, firmware, hardwired, or any combination thereof. Furthermore, the functional units may be integrated into a single processing unit, or each unit may exist physically separately, or two or more units may be integrated into a single unit. To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention have been clearly and completely described above in conjunction with the accompanying drawings.
