[0037] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.
[0038] In related technologies, the position adjustment of vehicle seats is mostly done by motor drive, such as Figure 1 As shown, the driver's seat, front passenger seat and other seats in the car are equipped with drive motors such as front and rear motors, height motors, and angle motors. Due to the characteristics of the motors, when working for a long time or when stalled, they are prone to overload and cause excessive temperature rise, or even burn the windings, reducing the safety of the seats; at the same time, due to the involvement of electromagnetic interference (EMI), in order to ensure the stability of the vehicle's power system, the seats and vehicle systems need to undergo strict electromagnetic compatibility (EMC) design, further increasing the vehicle's development cost and verification cycle.
[0039] In addition, in related technologies, seat massage and backrest adjustment generally use airbag adjustment. The seat contains two power sources (air drive and electric drive). A single seat contains 3-4 drive motors. Each drive motor requires a 12V power supply and a control harness for separate control. A single seat also contains an air pump and an airbag controller. The air pump and the airbag controller also require a separate 12V power supply and a control harness. The overall structure of the seat is highly complex.
[0040] An embodiment of the present application provides a seat 100 for a vehicle, which adopts an air source drive method to adjust the position of the seat 100. The seat 100 and the vehicle's air suspension system 300 share the air source, which can reduce the cost of the entire vehicle. At the same time, compared with motor drive, air source drive has no electromagnetic compatibility risk and no electronic winding heating problem, and supports long-term continuous operation. The integrated design of the seat 100 air circuit system eliminates complex wiring harnesses, reduces system complexity, and significantly improves the reliability and safety of the seat 100, making it suitable for various vehicle scenarios.
[0041] The seat 100 for a vehicle and the vehicle including the seat 100 provided in the embodiment of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.
[0042] The seat 100 for a vehicle according to an embodiment of the present application includes a seat body and a drive system, wherein the drive system includes an air supply branch, a first air use branch, a valve circuit controller 110 and a pneumatic motor.
[0043] In this embodiment, the input end of the air supply branch is connected to the air suspension system 300 of the vehicle, and the air suspension system 300 of the vehicle provides an air source for the seat 100 .
[0044] In actual implementation, the air suspension end valve body 320 of the air suspension system 300 is connected to the input end of the air supply branch, and the compressed air of the air tank 330 or the air pump 340 in the air suspension system 300 can be input into the seat 100 through the air suspension end valve body 320 and the air supply branch to drive the position adjustment of the seat 100.
[0045] It can be understood that the air suspension system 300 includes an air suspension 310, which refers to a suspension structure in which traditional steel coil springs are replaced by air springs. The air suspension end valve body 320 of the air suspension system 300 is also provided with a port connected to the air suspension 310, which can output the compressed air from the air tank 330 or the air pump 340 to the air suspension 310 through the air suspension end valve body 320, thereby realizing the adjustment of the vehicle body height and stiffness, as well as dynamic damping matching.
[0046] In actual implementation, the air suspension end valve body 320 can be a combination of multiple valves to control the opening and closing of different valves, thereby achieving air path on-off control of the seat 100 and the air suspension 310.
[0047] In this embodiment, the input end of the first air branch is connected to the output end of the air supply branch through the valve circuit controller 110, the input end of the pneumatic motor is connected to the output end of the first air branch, and the output end of the pneumatic motor is connected to the position adjustment component of the seat body.
[0048] Among them, the pneumatic motor is a device that uses flowing compressed air as power to achieve rotational force output.
[0049] In this embodiment, the valve circuit controller 110 is used to control the on-off of the air circuit between the air supply branch and the first air use branch, and the pneumatic motor is used to drive the position adjustment component to adjust the position of the seat body.
[0050] In actual implementation, the valve circuit controller 110 can be a combination of multiple valves to control the opening and closing of different valves to achieve on-off control of the gas circuit between the gas supply branch and the first gas consumption branch.
[0051] It is understandable that the drive system of the seat 100 may include a plurality of pneumatic motors, each of which is connected to the valve circuit controller 110 via a first air branch circuit.
[0052] For example, the drive system of the seat 100 includes pneumatic motor A, pneumatic motor B and pneumatic motor C, the valve circuit controller 110 connects the first air branch A, the first air branch B and the first air branch C, the input end of the pneumatic motor A is connected to the output end of the first air branch A, the input end of the pneumatic motor B is connected to the output end of the first air branch B, and the input end of the pneumatic motor C is connected to the output end of the first air branch C.
[0053] In this embodiment, the valve circuit controller 110 provides the air source of the air suspension system 300 to the corresponding pneumatic motor by controlling the on-off of the air circuit between the air supply branch and different first air branches, and the pneumatic motor then drives the corresponding position adjustment component to adjust the position of the seat body.
[0054] In some embodiments, the position adjustment component includes at least one of a front-back adjustment component, a height adjustment component, and an angle adjustment component; the pneumatic motor of the drive system includes at least one of a front-back pneumatic motor 101, a height pneumatic motor 102, and an angle pneumatic motor 103.
[0055] like Figure 2 As shown, the seat 100 includes a front and rear pneumatic motor 101, a height pneumatic motor 102 and an angle pneumatic motor 103, and the valve circuit controller 110 is connected to three first air branches (bold lines in the figure), and the output ends of these three first air branches are respectively connected to the input ends of the front and rear pneumatic motor 101, the height pneumatic motor 102 and the angle pneumatic motor 103.
[0056] The front and rear pneumatic motors 101 are used to connect with the front and rear adjustment components. The front and rear pneumatic motors 101 are connected to the valve circuit controller 110 through a first air branch. When the valve circuit controller 110 controls the air circuit between the air supply branch and the first air branch, the gas is input to the front and rear pneumatic motors 101, and the front and rear pneumatic motors 101 drive the front and rear adjustment components to move, thereby realizing the front and rear movement of the seat body.
[0057] The height pneumatic motor 102 is used to connect with the height adjustment component. The height pneumatic motor 102 is connected to the valve circuit controller 110 through a first air branch. When the valve circuit controller 110 controls the air circuit between the air supply branch and the first air branch, the gas is input to the height pneumatic motor 102, and the height adjustment component is driven by the height pneumatic motor 102 to realize the vertical lifting and lowering of the seat body.
[0058] The angle pneumatic motor 103 is used to connect with the angle adjustment component. The angle pneumatic motor 103 is connected to the valve circuit controller 110 through a first air branch. When the valve circuit controller 110 controls the air circuit between the air supply branch and the first air branch, the gas is input to the angle pneumatic motor 103, and the angle pneumatic motor 103 drives the angle adjustment component to operate, thereby realizing the backrest inclination adjustment of the seat body.
[0059] In actual implementation, the valve circuit controller 110 determines the position adjustment component that needs to be activated according to the adjustment requirements, controls the air supply branch and the corresponding first air branch to be connected, inputs compressed gas to the corresponding pneumatic motor, drives the position adjustment component to activate, and adjusts the position of the seat body.
[0060] For example, the valve circuit controller 110 determines that the position adjustment component that needs to be activated is the front and rear adjustment component based on the adjustment requirements. The front and rear adjustment components are connected to the front and rear pneumatic motors 101. The valve circuit controller 110 controls the air supply branch and the first air branch connected to the front and rear pneumatic motors 101 to be connected. The compressed gas is input to the front and rear pneumatic motors 101, and the front and rear pneumatic motors 101 drive the front and rear adjustment components to move, thereby realizing the front and rear movement of the seat body.
[0061] In an embodiment of the present application, a pneumatic motor is provided to drive a position adjustment component, and the gas of the air suspension system 300 is input to the seat 100 through the air supply branch. The valve circuit controller 110 controls the on-off of the air circuit between the air supply branch and the first air branch, and then supplies air to the pneumatic motor through the first air branch. The position adjustment of the seat 100 is achieved by adopting an air source drive method. The seat 100 and the air suspension system 300 share the air source, and the air circuit is integrated in the design, which eliminates the power wiring harness, control wiring harness and insurance components of the drive motor in the related technology. The system complexity is low, and the weight and cost of the seat 100 assembly can also be reduced.
[0062] It should be noted that the adjustment of the seat 100 is characterized by low frequency and short duration relative to the operation of the entire vehicle. The air source of the air suspension system 300 is used to drive the position adjustment of the seat 100, which will not affect the operating efficiency of the entire vehicle. The pneumatic motor has high temperature tolerance, and the heat generated during operation can be discharged through the pipeline. It can continue to work without heat, and there is no risk of motor stalling and burning, which can improve the system's continuous working ability and high product reliability. At the same time, the use of air source drive means that the seat 100 does not require EMC protection design, which can significantly reduce development costs and shorten the verification cycle.
[0063] According to the seat 100 for a vehicle provided in an embodiment of the present application, a pneumatic motor is provided to drive a position adjustment component of the seat body, and an air supply branch inputs the gas of the air suspension system 300 into the seat 100. The first air branch supplies air to the pneumatic motor. The valve circuit controller 110 controls the on-off of the air circuit between the air supply branch and the first air branch. The seat 100 and the air suspension system 300 share an air source, and the position of the seat 100 is adjusted by air drive. The air circuit is designed to be integrated, the system complexity is low, no EMC design is required, and it is safer and more reliable.
[0064] In some embodiments, the valve controller 110 is used to switch the gas input path and the gas output path of the pneumatic motor to control the rotation direction of the pneumatic motor.
[0065] It is understandable that by controlling the rotation direction of the pneumatic motor, the position adjustment component can be controlled to adjust the displacement direction of the seat 100, that is, the displacement direction can be regulated by switching the pneumatic motor between forward and reverse directions.
[0066] Taking the front and rear pneumatic motor 101 as an example, when the front and rear pneumatic motor 101 rotates forward, the front and rear adjustment assembly drives the seat body to move forward (forward here can refer to the direction of vehicle travel); when the front and rear pneumatic motor 101 rotates backward, the front and rear adjustment assembly drives the seat body to move backward.
[0067] In this embodiment, the air inlet and outlet of the pneumatic motor can be changed, or the main air source and control air source of the pneumatic motor can be changed, and the gas input path and the gas output path can be switched to realize the forward and reverse adjustment of the pneumatic motor.
[0068] For example, the pneumatic motor has three holes, hole No. 1 is for air intake, hole No. 2 is for exhaust, and when there is no air source at hole No. 3, the pneumatic motor rotates forward. After the valve circuit controller 110 switches the gas input path and the gas output path of the pneumatic motor, air is taken in at hole No. 3, and hole No. 2 is for exhaust. When there is no air source at hole No. 1, the pneumatic motor rotates reversely.
[0069] For another example, the pneumatic motor has two holes, hole 1 for air intake and hole 2 for exhaust, and the pneumatic motor rotates forward. After the valve circuit controller 110 switches the gas input path and the gas output path of the pneumatic motor, hole 2 for air intake and hole 1 for exhaust, and the pneumatic motor rotates reversely.
[0070] In actual implementation, the front and back, height and angle adjustment of the seat 100 can be driven by an air source, and the massage and backrest adjustment of the seat 100 can also be driven by an air source. The seat 100 system has an integrated air circuit design.
[0071] In some embodiments, the drive system may further include a second air branch and an airbag assembly.
[0072] In this embodiment, the input end of the second air branch is connected to the output end of the air supply branch through a valve circuit controller 110, the input end of the airbag assembly is connected to the output end of the second air branch, the airbag assembly is arranged on the seat body, and the valve circuit controller 110 is also used to control the on-off of the air circuit between the air supply branch and the second air branch.
[0073] It can be understood that the drive system of the seat 100 may include multiple airbag assemblies, each of which is connected to the valve circuit controller 110 through a second air branch. The valve circuit controller 110 provides an air source for the corresponding airbag assembly by controlling the on-off of the air circuit between the air supply branch and different second air branches, thereby realizing the massage and backrest adjustment functions of the seat 100.
[0074] In some embodiments, the airbag assembly includes at least one of a seat cushion airbag 121 , a backrest airbag 122 , and a side airbag 123 .
[0075] Among them, the seat cushion airbag 121 can be set in the seat cushion of the seat body, the backrest airbag 122 can be set in the backrest of the seat body (such as the shoulder or waist position of the occupant), and the side airbag 123 can be embedded in the side of the backrest of the seat 100. The massage and backrest adjustment functions of the seat 100 are realized by inflating and deflating the seat cushion airbag 121, the backrest airbag 122 and the side airbag 123.
[0076] like Figure 3 As shown, the seat 100 includes a seat cushion airbag 121, a backrest airbag 122 and a side airbag 123, and the valve circuit controller 110 is connected to three second air branches (bold lines in the figure), and the output ends of these three second air branches are respectively connected to the input ends of the seat cushion airbag 121, the backrest airbag 122 and the side airbag 123.
[0077] In this embodiment, an air source is used for driving, and the air source is shared with the vehicle's air suspension system 300. The valve circuit controller 110 is also used to control the on-off of the air circuit between the air supply branch and the first air branch and the second air branch, thereby realizing the position adjustment and massage functions of the seat 100. The power source (air source) of the seat 100 is single, the system complexity is low, and the weight and cost of the seat 100 assembly can be effectively reduced.
[0078] In related technologies, such as Figure 1 As shown, each motor needs to be connected to the seat adjuster, and the control software is integrated into the seat adjuster and the cockpit controller. At the same time, the seat adjuster also needs to be connected to the vehicle communication harness to realize the control function.
[0079] In an embodiment of the present application, a pneumatic motor is used to drive the position adjustment of the seat 100, simplifying the power wiring harness and communication wiring harness in the seat 100. The seat 100 control function can be integrated into the air suspension controller 350 of the air suspension system 300. The seat 100 control function can include the seat 100 position adjustment realized by the pneumatic motor, and can also include the seat 100 massage function realized by the airbag assembly.
[0080] In some embodiments, as Figure 4 As shown, the valve circuit controller 110 is communicatively connected with the air suspension controller 350 of the air suspension system 300 (shown as a dotted line). The air suspension controller 350 is used to control the on-off of the air circuit between the air suspension system 300 and the air supply branch. The air suspension controller 350 is also used to output control instructions to the valve circuit controller 110 to control the action of the valve circuit controller 110.
[0081] Among them, the air suspension controller 350 is the control unit of the air suspension system 300, which can monitor vehicle height, acceleration, speed and other signals in real time, perform suspension status adjustments, and improve vehicle comfort, handling and safety.
[0082] In actual implementation, the air suspension system 300 may include an air suspension 310, an air suspension end valve body 320, an air tank 330 and an air pump 340. The air suspension controller 350 may control the operation of the air pump 340 to provide compressed air. The air tank 330 is used to store compressed air. The air suspension end valve body 320 may provide compressed air to the air suspension 310 or the seat 100.
[0083] In this embodiment, when the position of the seat 100 needs to be adjusted, the air suspension controller 350 can control the air suspension end valve body 320 to open the air path from the air suspension system 300 to the air supply branch, and the air supply branch delivers a stable air source to the seat 100. The valve circuit controller 110 on the seat 100 controls the opening and closing of the air path between the air supply branch and the first air branch according to the control instructions of the air suspension controller 350, and drives the pneumatic motor to work with the air source to achieve position adjustment of the seat 100.
[0084] It can be understood that when the massage and backrest functions of the seat 100 need to be adjusted, the air suspension controller 350 can control the air suspension end valve body 320 to open the air path from the air suspension system 300 to the air supply branch, and the air supply branch delivers a stable air source to the seat 100. The valve circuit controller 110 on the seat 100 controls the on-off of the air path between the air supply branch and the second air branch according to the control instructions of the air suspension controller 350, and drives the airbag assembly to work with the air source to realize the adjustment of the massage and backrest functions of the seat 100.
[0085] In some embodiments, as Figure 5 As shown, the seat 100 may further include a seat adjustment module 130 .
[0086] The seat adjustment module 130 is in communication with the air suspension controller 350 . The seat adjustment module 130 is configured to receive user input and, in response to the user input, send an adjustment request for the seat 100 to the air suspension controller 350 .
[0087] In actual implementation, the seat adjustment module 130 can be a physical button, touch screen or voice module on the vehicle that can realize the adjustment functions of the seat 100 (position adjustment, massage and backrest adjustment, etc.). The seat adjustment module 130 receives user input, responds to the user input, generates adjustment requirements corresponding to the user input, and sends the adjustment requirements to the air suspension controller 350, and then the air suspension controller 350 outputs corresponding control instructions to the valve circuit controller 110.
[0088] It can be understood that the control of the seat 100 is integrated into the air suspension controller 350. The seat adjustment module 130 and the valve circuit controller 110 can be directly connected to the air suspension controller 350 through the CAN bus, or they can first connect to the communication wiring harness (CAN line, LIN line) closest to the seat adjustment module 130 and the valve circuit controller 110, and then realize communication interaction between different domains with the air suspension controller 350.
[0089] In actual implementation, the adjustment of the seat 100 (position, massage and backrest adjustment, etc.) can be achieved through the vehicle central control or CAN bus, or through the seat adjustment module 130.
[0090] When the adjustment is driven by the central control or CAN bus, the air suspension controller 350 controls the air suspension end valve body 320 to open the branch valve input to the seat 100 and deliver a stable air source. The air suspension controller 350 outputs a control instruction to the valve circuit controller 110 of the seat 100. The valve circuit controller 110 controls the operation of the valve body that needs to be adjusted according to the control instruction of the air suspension controller 350, controls the air circuit between the air supply branch and the first air branch and the second air branch, and realizes the adjustment of the seat 100 by using the air source drive.
[0091] When adjusting through the seat adjustment module 130, the seat adjustment module 130 sends the adjustment demand to the air suspension controller 350 through the communication harness. The air suspension controller 350 controls the air suspension end valve body 320 to open the branch valve input to the seat 100 and deliver a stable air source. The air suspension controller 350 outputs a control instruction to the valve circuit controller 110 of the seat 100. The valve circuit controller 110 controls the operation of the valve body that needs to be adjusted according to the control instruction of the air suspension controller 350, controls the air circuit between the air supply branch and the first air branch and the second air branch, and realizes the adjustment of the seat 100 by using the air source drive.
[0092] It is understandable that multiple seats 100 on the vehicle can share the air source of the air suspension system 300 , and the control of the multiple seats 100 can also be integrated into the air suspension controller 350 of the air suspension system 300 .
