DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solution and advantages of this application more clear, the following is a further detailed description of this application in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain this application and do not limit the scope of protection of this application.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0045] Vehicles such as sedans, SUVs, multi-purpose vehicles, off-road vehicles, buses, and RVs bring many conveniences to people's lives, work, and studies, and play an important role in people's travel. However, there are many types and brands of vehicles, which makes it possible for people to choose from many vehicles. How to win people's favor and improve product competitiveness has become an issue that vehicle manufacturers are paying more and more attention to.

[0046] At present, with the improvement of people's living standards, people have higher and higher requirements for the comfort of seats.

[0047] In the related art, since the width of the seat is limited by factors such as the length of the vehicle, the position of other seats, and the width design of the aisle, the width of the seat is usually not adjustable, and the inclination of the seat cushion is adjusted through the inclination adjustment mechanism of the seat cushion to better support the user's hips and legs. If the user's legs are long, even if the inclination of the seat cushion is adjusted, due to the insufficient width of the seat and / or the insufficient aisle, the user's thighs are mostly suspended, which leads to insufficient support for the user's legs, insufficient riding comfort, and is not conducive to improving the user experience of the vehicle.

[0048] Based on this, the present application provides a seat cushion that can adjust the seat cushion inclination angle and the length of the seat cushion support surface in the width direction of the seat cushion, so as to better meet the riding comfort needs of occupants of different body shapes.

[0049] In order to better understand the seat cushion of the present application, a vehicle to which the seat cushion is applied is used for explanation.

[0050] like Figure 1 as well as Figure 2 As shown, the present application provides a vehicle 1, including a mobile device 10 and a seat 20. The mobile device 10 has a seating space 10a. The seat 20 includes a seat cushion 100, a frame 200 and a backrest 300. The seat cushion 100 is mounted on the frame 200, and the backrest 300 is connected to the frame 200. The seat 20 is disposed in the seating space 10a through the frame 200. When the vehicle 1 is assembled, the seat 20 is disposed in the seating space 10a through the frame 200, which is convenient for passengers to sit. When the seat 20 is assembled, the seat cushion 100 and the backrest 300 are assembled together through the frame 200, which is convenient for users to use the seat cushion 100 to support their buttocks and the backrest 300 to support their backs, so that users can sit comfortably on the seat 20.

[0051] Among them, combined Figure 3As shown, the seat cushion 100 includes a mounting member 110 connected to the frame 200, a first supporting member 120, a second supporting member, a seat cushion body 140 and a driving member 150. The mounting member 110 includes a first connecting portion 111 and a first side portion 112 spaced apart from the first connecting portion 111 along the width direction of the seat cushion 100. The first supporting member 120 includes a first bearing body 121, and the first bearing body 121 includes a first rotating portion 1211 and a second connecting portion 1212 spaced apart from the first rotating portion 1211 along the width direction of the seat cushion 100. The first rotating portion 1211 is rotatably connected to the first connecting portion 111. Relative to the first rotating portion 1211, the second connecting portion 1212 is disposed close to the first side portion 112. The second supporting member is rotatably connected to the second connecting portion 1212, and at least a portion of the second supporting member extends in a direction away from the first rotating portion 1211 along the width direction of the seat cushion 100. The seat cushion body 140 includes a first cushion body 141 fixedly mounted on the first carrier 121 and a second cushion body 142 fixedly mounted on the second supporting member, and the first cushion body 141 and the second cushion body 142 cooperate to form a supporting surface. The driving component 150 includes a first driving assembly 151 that is transmission-coordinated with the first carrier 121 and a second driving assembly 152 that is transmission-coordinated with the second supporting member. The first driving assembly 151 can drive the first carrier 121 to rotate relative to the mounting member 110 to adjust the inclination angle of the first cushion body 141. The second driving assembly 152 can drive the second supporting member to rotate relative to the mounting member 110 to adjust the length of the supporting surface in the width direction of the seat cushion 100.

[0052] When the vehicle 1 is in use, since the second supporting member is rotatably connected to the first supporting body, when the second driving assembly 152 is stationary, the second supporting member rotates with the first supporting body. When the middle support of the seat cushion 100 is insufficient and / or the fit is insufficient, and the inclination angle of the seat cushion 100 needs to be adjusted, the second driving assembly 152 is stationary, and the first driving assembly 151 drives the first carrier 121 to rotate to drive the first supporting body and the second supporting member to rotate together, so that the support surface formed by the first cushion body 141 and the second cushion body 142 rotates relative to the mounting member 110, thereby realizing a larger inclination angle of the seat cushion 100 to better support the user's buttocks and legs.

[0053] When the support and / or fit between the front end of the seat cushion 100 and the user's legs is still insufficient after the inclination of the seat cushion 100 is adjusted, the width of the seat cushion 100 needs to be adjusted. At this time, the first drive assembly 151 does not move, and the second drive assembly 152 drives the second bearing member to rotate to increase the length of the support surface in the width direction of the seat cushion 100, so as to increase the contact area between the seat cushion 100 and the user's legs and better support the user's thighs or thighs and calves. In this way, the vehicle 1 can better meet the riding comfort needs of passengers of different body shapes and improve the user experience.

[0054] In addition, when the user gets on or off the vehicle, the second driving component 152 is used to drive the second bearing member to rotate to shorten the length of the support surface in the width direction of the seat cushion 100 to increase the aisle width and facilitate the user to get on or off the vehicle.

[0055] When the inclination angle of the seat cushion 100 is too large, causing the user's legs to be suspended in the air, the second drive component 152 does not move, and the first drive component 151 drives the first carrier 121 to rotate to drive the first supporting body and the second supporting member to rotate together, so that the supporting surface formed by the first cushion body 141 and the second cushion body 142 rotates relative to the mounting member 110, thereby reducing the inclination angle of the seat cushion 100. While being able to support the user's buttocks and legs, the user's legs can be supported on the ground, so that the user can sit comfortably on the seat cushion 100.

[0056] When the front end of the seat cushion 100 supports and / or fits the user's legs too tightly, it is necessary to adjust the width of the seat cushion 100. At this time, the first drive assembly 151 does not move, and the second drive assembly 152 drives the second bearing member to rotate to shorten the length of the support surface in the width direction of the seat cushion 100, so as to reduce the contact area between the seat cushion 100 and the user's legs, avoid the front end of the seat cushion 100 supporting and / or fitting the user's legs too tightly, so that the user's thigh or thigh and calf are comfortably supported by the second pad body 142.

[0057] See attached Figures 2 to 5 As shown, in some embodiments, the width direction of the seat cushion 100 is the X-axis direction, and the thickness direction of the seat cushion 100 is the Z-axis direction.

[0058] In some embodiments, the width direction of the seat cushion 100 is arranged in the same direction as the length direction of the vehicle 1 , and the thickness direction of the seat cushion 100 is arranged in the same direction as the height direction of the vehicle 1 .

[0059] like Figures 3 to 5 In some embodiments shown, the seat cushion body 140 further includes an outer cover 160 that covers the first cushion body 141 and the second cushion body 142, and the support surface is used to support the outer cover 160. In this way, the outer cover 160 is used to cover and protect the first cushion body 141 and the second cushion body 142, which can improve the durability of the seat cushion 100 and improve the overall aesthetics of the seat cushion 100.

[0060] The material of the outer cover 160 includes at least one of leather, fabric, etc.

[0061] It should be noted that there are many specific implementation methods for the first driving assembly 151, as long as it can drive the first carrier to rotate. For example, the first carrier 121 is driven to rotate by a motor with a power-off self-holding function. For another example, the first carrier 121 is driven to rotate by a rotary power output device with a self-locking function. For another example, the first carrier 121 is driven to rotate by an airbag, etc.

[0062] It should be noted that there are many specific implementation methods for the second drive assembly 152, as long as it can drive the second bearing member to rotate. For example, the second bearing member is driven to rotate by a motor with a power-off self-holding function. For another example, the second bearing member is driven to rotate by a rotary power output device with a self-locking function. For another example, the second bearing member is driven to rotate by an airbag, etc.

[0063] like Figure 3 , Figure 4 or Figure 5 As shown, in some embodiments, at least a portion of the first carrier 121 and the mounting member 110 are spaced apart from each other along the thickness direction of the seat cushion 100 to form a first adjustment cavity 101, and at least a portion of the first drive assembly 151 is disposed in the first adjustment cavity 101. In this way, by providing the first adjustment cavity 101, it is convenient to dispose at least a portion of the first drive assembly 151 in the first adjustment cavity 101, so that the structure of the seat cushion 100 is more compact.

[0064] like Figure 3As shown, in some embodiments, the first driving assembly 151 includes a first airbag 1511 and a first pneumatic power source 1512. At least a portion of the first airbag 1511 is disposed in the first regulating chamber 101, and is respectively in contact with the first carrier 121 and the mounting member 110. The first pneumatic power source 1512 is in communication with the first airbag 1511 to control the first airbag 1511 to swell in the direction of lifting the first carrier 121 or to shrink in the direction away from the first carrier 121. In this way, at least a portion of the first airbag 1511 is disposed in the first regulating chamber 101, so that the first carrier 121 and the mounting member 110 are used to protect the first airbag 1511. The first airbag 1511 is in contact with the first carrier 121 and the mounting member 110 respectively, and then the first airbag 1511 can lift up the first carrier 121 after the first gas power source 1512 is inflated, and drive the support surface formed by the first cushion body 141 and the second cushion body 142 to rotate relative to the mounting member 110, thereby increasing the inclination angle of the seat cushion 100 to better support the user's buttocks and legs. When the inclination angle of the seat cushion 100 is too large, causing the user's legs to hang in the air, the first airbag 1511 contracts after the first gas power source 1512 inhales, and can pull the first carrier 121, and drive the support surface formed by the first cushion body 141 and the second cushion body 142 to rotate relative to the mounting member 110, thereby reducing the inclination angle of the seat cushion 100, while being able to support the user's buttocks and legs, allowing the user's legs to land on the ground for support, so that the user can sit comfortably on the seat cushion 100.

[0065] like Figure 3 As shown, in some embodiments, the first driving assembly 151 further includes a first gas tank 1513 connected to the first air bag 1511. The first pneumatic power source 1512 is connected to the first air bag 1511 through the first gas tank 1513. In this way, it is convenient to use the first gas tank 1513 to smoothly deliver high-pressure gas to the first air bag 1511, or to recover the gas of the first air bag 1511, so that the seat cushion 100 is quieter during the tilt adjustment process. When the air pressure of the first gas tank 1513 is less than the set value, the first pneumatic power source 1512 replenishes the high-pressure gas to the first gas tank 1513.

[0066] In one example, the first gas tank 1513 and the first gas power source 1512 are fixed to the mounting member 110 and are disposed outside the first adjustment chamber 101. The first airbag 1511 is disposed in the first adjustment chamber 101. In this way, the space of the first adjustment chamber 101 is fully utilized to accommodate the first airbag 1511, and the first airbag 1511 is utilized to achieve a wide range of seat cushion 100 tilt adjustment.

[0067] Alternatively, if Figure 3As shown, in some embodiments, the driving component 150 further includes an air delivery pipe 153, and the first air tank 1513 is connected to the first air bag 1511 through at least one air delivery pipe 153, and the first air tank 1513 is connected to the first air bag 1511 through at least one air delivery pipe 153. The air delivery pipe 153 includes a hose or a telescopic pipe. In this way, the arrangement of the air delivery pipe 153 allows the positions of the first air bag 1511 and the first air tank 1513 to be flexibly arranged, and is also convenient for avoiding other structures of the seat cushion 100.

[0068] like Figure 3 As shown, in some embodiments, the first supporting member 120 further includes a second carrier 122, and the second carrier 122 is bent and connected to the first carrier 121, so that at least a portion of the second carrier 122 is arranged toward the first side portion 112, and at least a portion of the second carrier 122 and at least a portion of the second supporting member are spaced apart along the thickness direction of the seat cushion 100 to form a second adjustment cavity 102, and at least a portion of the second drive assembly 152 is arranged in the second adjustment cavity 102. In this way, the second adjustment cavity 102 is formed by the cooperation of the second carrier 122 and the second supporting member, so that at least a portion of the first and second drive assemblies are arranged in the second adjustment cavity 102, making the structure of the seat cushion 100 more compact.

[0069] In addition, the second carrier 122 is bent and connected to the first carrier 121, so that the second carrier 122 and the second supporting member rotate with the first carrier 121, thereby facilitating the first carrier 121 to synchronously drive at least partial rotation of the second carrier and the second driving assembly 152, thereby facilitating width adjustment of the seat cushion 100.

[0070] In combination with the above embodiments, Figure 3 As shown, in some embodiments, the second driving assembly 152 includes a second airbag 1521 and a second pneumatic power source 1522. At least part of the second airbag 1521 is disposed in the second regulating chamber 102 and abuts against the second carrier 122 and the second supporting member, respectively. The second pneumatic power source 1522 is connected to the second airbag 1521 to control the second airbag 1521 to swell in the direction of pushing up the second supporting member or shrink in the direction away from the second supporting member. In this way, at least part of the second airbag 1521 is disposed in the second regulating chamber 102, so that the second airbag 1521 can be protected by the second carrier 122 and the mounting member 110. The second airbag 1521 is respectively in contact with the second supporting body 122 and the mounting member 110, so that after being expanded by the second pneumatic source 1522, the second airbag 1521 can lift up the second supporting member and drive the second cushion body 142 to rotate relative to the first cushion, so as to increase the length of the supporting surface in the width direction of the seat cushion 100, thereby increasing the contact area between the seat cushion 100 and the user's legs and better supporting the user's thighs or thighs and calves.

[0071] When the front end of the seat cushion 100 supports and / or fits the user's legs too tightly, the width of the seat cushion 100 needs to be shortened. At this time, the second airbag 1521 contracts after the second gas power source 1522 inhales, which can pull the second bearing member to rotate, and drive the second cushion body 142 to rotate relative to the first cushion, so as to reduce the length of the supporting surface in the width direction of the seat cushion 100, thereby reducing the contact area between the seat cushion 100 and the user's legs, avoiding the front end of the seat cushion 100 supporting and / or fitting the user's legs too tightly, so that the user's thighs or thighs and calves are comfortably supported by the second cushion body 142.

[0072] like Figure 2 As shown, in some embodiments, the second driving assembly 152 further includes a second gas tank 1523 connected to the second air bag 1521, and the second pneumatic power source 1522 is connected to the second air bag 1521 through the second gas tank 1523. In this way, it is convenient to use the second gas tank 1523 to smoothly deliver high-pressure gas to the second air bag 1521, so that the seat cushion 100 is more quiet when adjusted. When the air pressure of the second gas tank 1523 is less than the set value, the second pneumatic power source 1522 replenishes the second gas tank 1523 with high-pressure gas.

[0073] In combination with any of the above embodiments of the second gas power source 1522, Figure 4As shown, in some embodiments, the first driving component 151 includes a first airbag 1511 connected to the second pneumatic power source 1522, and the first airbag 1511 is respectively in contact with the first carrier 121 and the mounting member 110; the driving component 150 also includes a control valve 154, and the second air tank 1523 is respectively connected to the first airbag 1511 and the second airbag 1521 through the control valve 154, and the control valve 154 is used to control the connection or isolation of the first airbag 1511 and the second air tank 1523 and the connection or isolation of the second airbag 1521 and the second air tank 1523. In this way, when the inclination angle of the seat cushion 100 needs to be adjusted, the control valve 154 is used to control the isolation of the second airbag 1521 and the second air tank 1523, and control the connection of the first airbag 1511 and the second air tank 1523 (that is, the control valve 154 is in the first connection state). It is convenient to use the second gas tank 1523 to smoothly deliver high-pressure gas to the first airbag 1511, or to recover the gas of the first airbag 1511, so as to drive the first carrier 121 to rotate and drive the first support body and the second support member to rotate together. Then the support surface formed by the first cushion body 141 and the second cushion body 142 is rotated relative to the mounting member 110, so as to adjust the inclination angle of the seat cushion 100 to better support the user's buttocks and legs. When the user needs to adjust the width of the seat cushion 100. At this time, the control valve 154 is used to control the second airbag 1521 to be connected with the second gas tank 1523, and the first airbag 1511 is controlled to be isolated from the second gas tank 1523 (that is, the control valve 154 is in the second connection state). It is then convenient to use the second gas tank 1523 to smoothly deliver high-pressure gas to the second airbag 1521, or to recover the gas of the first airbag 1511, so as to drive the second bearing member to rotate to adjust the length of the support surface in the width direction of the seat cushion 100, so as to better support the user's thigh or thigh and calf. In this way, the seat cushion 100 can adjust the inclination of the seat cushion 100 and the length of the support surface of the seat cushion 100 in the width direction of the seat cushion 100, which can better meet the riding comfort requirements of passengers of different body shapes. In addition, during the adjustment process of the seat 20, the noise is small and the quietness is good, which is conducive to improving the user experience.

[0074] It should be noted that the control valve 154 can be implemented in a variety of ways, including but not limited to a switch valve (such as a solenoid valve), a flow-blocking assembly (such as a motor + a rotatable baffle), etc., which can realize the on-off control of the fluid by an electrically controlled switch device. For example, the control valve 154 includes a multi-way valve, and the switching between the first connected state and the second connected state is realized by the multi-way valve. The multi-way valve includes a switch valve with more than three connecting parts, such as a three-way valve, a four-way valve, and a five-way valve. For another example, the control valve 154 includes at least two two-way valves, and the switching between the first connected state and the second connected state is realized by the cooperation of at least two two-way valves.

[0075] It should be noted that there may be many specific implementations of the first pneumatic power source 1512 and the second pneumatic power source 1522, including air pumps, air cylinders, and the like.

[0076] like Figure 4 As shown, in one example, the control valve 154, the second air tank 1523 and the second pneumatic power source 1522 are fixed to the mounting member 110 and are arranged outside the first regulating chamber 101 and the second regulating chamber 102. The first airbag 1511 is arranged in the first regulating chamber 101. The second airbag 1521 is arranged in the second regulating chamber 102. In this way, the space of the first regulating chamber 101 is fully utilized to accommodate the first airbag 1511, and the first airbag 1511 is used to achieve a wide range of seat cushion 100 tilt angle adjustment. The space of the second regulating chamber 102 is fully utilized to accommodate the second airbag 1521, and the second airbag 1521 is used to achieve a wide range of seat cushion 100 length adjustment in the width direction.

[0077] In combination with the embodiment of the first pneumatic source 1512, in some embodiments, the first pneumatic source 1512 and the second pneumatic source 1522 are the same device, the first air tank 1513 and the second air tank 1523 are the same device, and the control valve 154 can be used to supply air or inhale air to the first airbag 1511 and the second airbag 1521 respectively.

[0078] In combination with any of the above-mentioned embodiments of the second gas storage tank 1523, Figure 4 As shown, in some embodiments, the driving component 150 further includes an air delivery pipe 153, and the second air tank 1523 is connected to the second air bag 1521 through at least one air delivery pipe 153. The air delivery pipe 153 includes a hose or a telescopic pipe. In this way, the arrangement of the air delivery pipe 153 allows the positions of the second air bag 1521 and the second air tank 1523 to be flexibly arranged, and is also convenient for avoiding other structures of the seat cushion 100. Moreover, the air delivery pipe 153 can follow the movement without interfering with the second carrier 122 rotating with the first carrier.

[0079] The gas transmission pipe 153 includes a nylon tube and other high-pressure resistant hoses used for natural gas transmission.

[0080] Combined with the above-mentioned embodiment of the first regulating chamber 101, as Figure 5As shown, in some embodiments, the first drive assembly 151 includes a first telescopic driver 155 disposed in the first adjustment cavity 101. The first telescopic driver 155 includes a first fixed end 1551 and a first telescopic end 1552 disposed opposite to the first fixed end 1551. One of the first fixed end 1551 and the first telescopic end 1552 is fixedly connected to the first carrier 121, and the other is fixedly connected to the mounting member 110. When the inclination angle of the seat cushion 100 needs to be adjusted, the second drive assembly 152 does not move, and the first telescopic end 1552 of the first telescopic driver 155 is controlled to telescopically move to drive the first carrier 121 to rotate, and the first supporting body and the second supporting member are driven to rotate together, so that the support surface formed by the first cushion body 141 and the second cushion body 142 rotates relative to the mounting member 110, thereby realizing the inclination angle adjustment of the seat cushion 100 to better support the user's buttocks and legs.

[0081] It should be noted that the specific implementation method of the first telescopic drive 155 includes but is not limited to power equipment such as pneumatic rods, hydraulic rods, linear motors, etc. that directly drive the telescopic movement of the first telescopic end 1552, and also includes a telescopic mechanism that indirectly realizes the telescopic movement of the first telescopic end 1552 by using a gear rack assembly + servo motor, a screw nut assembly + servo motor, a flexible transmission assembly + servo motor, etc.

[0082] In combination with the above-mentioned embodiment of the second regulating chamber 102, as Figure 5 As shown, in some embodiments, the second drive assembly 152 includes a second telescopic driver 156 disposed in the second adjustment chamber 102, and the second telescopic driver 156 includes a second fixed end 1561 and a second telescopic end 1562 disposed opposite to the second fixed end 1561, and one of the second fixed end 1561 and the second telescopic end 1562 is fixedly connected to the second carrier 122, and the other is fixedly connected to the second supporting member. When the seat cushion 100 still cannot support the thigh knee end after the inclination angle is adjusted, the user needs to adjust the width of the seat cushion 100. At this time, the first drive assembly 151 does not move, and the second telescopic end 1562 of the second telescopic driver 156 is controlled to telescopically move to drive the second supporting member to rotate to adjust the length of the support surface in the width direction of the seat cushion 100, so as to better support the user's thigh or thigh and calf.

[0083] It should be noted that the specific implementation method of the second telescopic drive 156 includes but is not limited to power equipment such as pneumatic rods, hydraulic rods, linear motors, etc. that directly drive the telescopic movement of the second telescopic end 1562, and also includes a telescopic mechanism that indirectly realizes the telescopic movement of the second telescopic end 1562 by using a gear rack assembly + servo motor, a screw nut assembly + servo motor, a flexible transmission assembly + servo motor, etc.

[0084] like Figure 3 , Figure 4 or Figure 5 As shown, in some embodiments, the seat cushion 100 further includes a first pressure detection device 170. The first pressure detection device 170 is sandwiched between the first cushion body 141 and the outer cover 160, and is used to detect the pressure data of the first cushion body 141. In this way, it is convenient to obtain the pressure data of the first cushion body 141 through the first pressure detection device 170, and it is convenient to judge whether the inclination angle of the seat cushion 100 needs to be adjusted according to the pressure length of the first cushion body 141 in the width direction of the seat cushion 100. For example, when the pressure length of the first cushion body 141 in the width direction of the seat cushion 100 is less than the first threshold, it is necessary to increase the inclination angle of the seat cushion 100 to better support the user.

[0085] In combination with any of the above embodiments, Figure 3 , Figure 4 or Figure 5 As shown, in some embodiments, the seat cushion 100 further includes a second pressure detection device 180. The second pressure detection device 180 is sandwiched between the second cushion body 142 and the outer cover 160, and is used to detect the pressure data of the second cushion body 142. In this way, it is convenient to obtain the pressure data of the second cushion body 142 through the second pressure detection device 180, and it is convenient to judge whether the inclination angle of the seat cushion 100 needs to be adjusted according to the pressure length of the second cushion body 142 in the width direction of the seat cushion 100. For example, when the pressure length of the second cushion body 142 in the width direction of the seat cushion 100 is less than the second threshold value, the front end of the seat cushion 100 does not support the user. At this time, it is necessary to drive the second bearing member to rotate through the second drive assembly 152 to increase the length of the support surface in the width direction of the seat 20 to better support the user.

[0086] In combination with the aforementioned first pressure detection device 170, if the pressure bearing length of the first cushion body 141 in the width direction of the seat cushion 100 is greater than the first threshold, and the pressure bearing length of the second cushion body 142 in the width direction of the seat cushion 100 is less than the second threshold, the front end of the seat cushion 100 does not support the user. At this time, the angle of the first cushion body 141 can remain unchanged. The second bearing member is driven to rotate by the second driving component 152 to increase the length of the support surface in the width direction of the seat 20 to better support the user.

[0087] However, if the pressure-bearing length of the first cushion body 141 in the width direction of the seat cushion 100 is also less than the first threshold value, and the pressure-bearing length of the second cushion body 142 in the width direction of the seat cushion 100 is less than the second threshold value, the front end of the seat cushion 100 does not support the user. At this time, the inclination angle of the seat cushion 100 can be adjusted by the first drive component 151 so that the pressure-bearing length of the first cushion body 141 in the width direction of the seat cushion 100 is greater than the first threshold value. If, at this time, the pressure-bearing length of the second cushion body 142 in the width direction of the seat cushion 100 is still less than the second threshold value, the second drive component 152 is used to drive the second bearing member to rotate to increase the length of the support surface in the width direction of the seat 20 to better support the user.

[0088] It should be noted that there are many specific implementations of the "first pressure detection device 170" and / or the "second pressure detection device 180", including but not limited to pressure stickers.

[0089] like Figure 6 As shown, in some embodiments, the mounting member 110 is slidably connected to the frame 200, and the seat 20 further includes a first driving mechanism 400 for driving the mounting member 110 to move relative to the frame 200 along the width direction of the seat cushion 100. In this way, the first driving mechanism 400 can be used to realize the front and rear movement of the seat 20, so that the user can flexibly adjust the position of the seat 20 according to personal habits.

[0090] like Figure 6 As shown, in some embodiments, the mounting member 110 is slidably connected to the frame 200, and the seat 20 further includes a second driving mechanism 500 for driving the mounting member 110 to move relative to the frame 200 along the thickness direction of the seat cushion 100. In this way, the second driving mechanism 500 can be used to realize the up and down movement of the seat 20, so that the user can flexibly adjust the height of the seat 20 according to personal habits.

[0091] like Figure 6 As shown, in some embodiments, the backrest 300 is rotatably connected to the frame 200, and the seat 20 further includes a third driving mechanism 600 for driving the backrest 300 to rotate. In this way, the backrest 300 can be rotated by the third driving mechanism 600, so that the user can flexibly adjust the angle between the backrest 300 and the seat cushion 100 according to personal habits to better support the user.

[0092] like Figure 6 As shown, in some embodiments, the vehicle 1 further includes a control device 30, which is in communication with the driving component 150 and the first pressure detection device 170 and the second pressure detection device 180. In this way, the control device 30 can obtain the pressure information of the first cushion body 141 and the pressure information of the second cushion body 142 to control the movement of the driving component 150 to adjust the seat cushion 100 to a suitable position to better support the user.
