[0038] Currently, rotating seats are mostly controlled manually, and the accuracy of judging the locked and unlocked states of the limit components is low. Users need to rotate the seats back and forth multiple times, resulting in a poor user experience.

[0039] In view of this, the present application provides a vehicle seat system and a vehicle. The vehicle seat system includes a seat, a limit assembly, a limit sensor and a control device. The seat is rotatably arranged on the body of the vehicle. The limit assembly is connected to the seat, and includes a locked state and an unlocked state. When the limit assembly is in the locked state, the seat is prevented from rotating relative to the body. When the limit assembly is in the unlocked state, the seat is allowed to rotate relative to the body. The limit sensor is used to detect the state of the limit assembly. The control device is connected to the limit sensor and the seat, and is used to control the rotation of the seat in response to rotation trigger information input by the user, wherein, if the limit sensor detects that the limit assembly is in the locked state, the limit assembly is controlled to switch to the unlocked state, and after the limit assembly is switched to the unlocked state, the seat rotation is controlled.

[0040] The vehicle seat system provided in this application detects the status of the limit component by setting a limit sensor, improves the accuracy of judging the status of the limit component, and achieves good coordination between the seat rotation and the limit component. The user does not need to repeatedly rotate the seat to lock or unlock, thereby improving the user's experience of rotating the seat.

[0041] The vehicle provided in the present application includes a vehicle seat system.

[0042] The vehicle seat system and the vehicle of the present application are described in detail below with reference to the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other.

[0043] The vehicle of the embodiment of the present application includes a vehicle seat system 10. The vehicle includes but is not limited to a sedan, SUV, off-road vehicle, or other power-driven non-track-borne vehicle; the power source of the vehicle can be fuel or a power battery, which is not limited in the present application.

[0044] FIG1 is a system block diagram of an embodiment of a vehicle seat system 10 of the present application. FIG2 is a schematic structural diagram of the vehicle seat system 10 shown in FIG1 . The vehicle seat system 10 of the embodiment of the present application includes a seat 100, a limit assembly 200, a limit sensor 300, and a control device 400. The seat 100 is rotatably arranged on the vehicle body. For example, the seat 100 can rotate forward and backward relative to the vehicle body. The limit assembly 200 is connected to the seat 100 and includes a locked state and an unlocked state. When the limit assembly 200 is in the locked state, the seat 100 is prevented from rotating relative to the vehicle body. When the limit assembly 200 is in the unlocked state, the seat 100 is allowed to rotate relative to the vehicle body. The limit sensor 300 is used to detect the state of the limit assembly 200. The control device 400 is connected to the limit sensor 300 and the seat 100 and is used to control the rotation of the seat 100 in response to rotation trigger information input by the user. If the limit sensor 300 detects that the limit assembly 200 is in the locked state, the control device 400 controls the limit assembly 200 to switch to the unlocked state. After the limit assembly 200 switches to the unlocked state, the control device 400 controls the rotation of the seat 100. The vehicle seat system 10 of the embodiment of the present application uses the limit sensor 300 to detect the state of the limit assembly 200, improves the accuracy of determining the state of the limit assembly 200, and achieves good coordination between the rotation of the seat 100 and the limit assembly 200. The user does not need to repeatedly rotate the seat 100 to lock or unlock it, thereby improving the user's experience of rotating the seat 100.

[0045] It should be noted that the seat 100 can rotate forward and backward relative to the vehicle body around its central axis, and the seat 100 can rotate from facing the front of the vehicle to facing the rear of the vehicle. The rotatable seat 100 can improve the user's riding comfort and enable the vehicle to have multiple scenarios and multiple space layouts. The rotatable angle range of the seat 100 may include 0° to 360°, 0° to 270°, 0° to 180°, and other angle ranges, which are not limited in this application. The seat 100 can rotate clockwise or counterclockwise in the horizontal direction. The rotation strategy of the seat 100 can be determined based on the current position and target position of the seat 100, and the user can also customize the rotation direction to easily and quickly rotate the seat 100 to the target position. The rotation trigger information is the rotation control instruction issued by the user to the vehicle seat system 10, which may include but is not limited to the rotation angle information, rotation speed information, rotation direction information, and other information for controlling the rotation of the seat 100. The limit sensor 300 may include a micro switch.

[0046] As shown in FIG2 , in some embodiments, the vehicle seat system 10 includes a rotating upper plate 510. The seat 100 may further be provided with a plurality of bolt holes 110, and the rotating upper plate 510 is connected to the seat 100 via fixing bolts 120. Of course, the connection method between the rotating upper plate 510 and the seat 100 is not limited to bolt connection, and may also include other connection methods such as rivet connection and welding. It should be noted that the shape of the rotating upper plate 510 is not limited to the shape shown in FIG2 . When the seat 100 rotates relative to the vehicle body, the seat 100 drives the rotating upper plate 510 to rotate relative to the vehicle body.

[0047] In some embodiments, the vehicle seat system 10 includes a rotating lower plate 520, which is fixed to the vehicle body. The seat 100 can rotate relative to the rotating lower plate 520. The rotating upper plate 510 and the rotating lower plate 520 are arranged relative to each other. When the seat 100 rotates relative to the vehicle body, the rotating upper plate 510 rotates relative to the rotating lower plate 520. The rotating lower plate 520 is provided with a locking slot 523. The limiting assembly 200 can rotate relative to the rotating lower plate 520. The limiting assembly 200 has a first position and a second position. When the limiting assembly 200 is in the first position, the limiting assembly 200 is in an unlocked state. When the limiting assembly 200 is in the second position and the limiting assembly 200 is located in the locking slot 523, the limiting assembly 200 is in a locked state.

[0048] In some embodiments, the limiting assembly 200 may include a locking pin 210 and a limiting hole 512. The locking pin 210 is located in the limiting hole 512 and is movable within the limiting hole 512. The limiting hole 512 includes an inner side and an outer side. When the locking pin 210 is located on the inner side of the limiting hole 512, the limiting assembly 200 is in a first position; when the locking pin 210 is located on the outer side of the limiting hole 512, the limiting assembly 200 is in a second position. The inner side and the outer side of the limiting hole 512 are defined relative to the rotating upper disk 510. As shown in FIG. 2 , the inner side of the limiting hole 512 is close to the center of the rotating upper disk 510, while the outer side of the limiting hole 512 is close to the edge of the rotating upper disk 510.

[0049] Referring to FIG. 2 , a lock slot 523 can be provided on the edge of the rotating lower disk 520, oriented toward the center of the rotating lower disk 520, to allow the lock pin 210 to fall into the lock slot 523. When the lock pin 210 is located outside the limiting hole 512 and rotated into the lock slot 523, the limiting assembly 200 is in a locked state. When the lock pin 210 is located outside the limiting hole 512 and rotated out of the lock slot 523, the limiting assembly 200 is in an unlocked state. When the lock pin 210 is located inside the limiting hole 512, the distance between the lock pin 210 and the lock slot 523 is greater, and therefore, the limiting assembly 200 remains in the unlocked state. The lock slot 523 can include a first lock slot 523a and a second lock slot 523b, which are arranged opposite each other on the rotating lower disk 520. Furthermore, the limit sensor 300 includes a first limit sensor 310 and a second limit sensor 320. The first limit sensor 310 is disposed near the first lock slot 523a, and the second limit sensor 320 is disposed near the second lock slot 523b, to respectively detect whether the lock pin 210 falls into the first lock slot 523a and the second lock slot 523b.

[0050] In some embodiments, the vehicle seat system 10 includes an unlocking drive device 610 and a rotation drive device 620. The unlocking drive device 610 is connected to the position-limiting assembly 200 and is used to control the position-limiting assembly 200 to switch between a first position and a second position. The rotation drive device 620 is connected to the seat 100 and is used to drive the seat 100 to rotate relative to the vehicle body and drive the position-limiting assembly 200 to rotate relative to the lock slot 523. The unlocking drive device 610 may include an unlocking drive motor, and the rotation drive device 620 may include a rotation drive motor. The rotating upper plate 510 may include an upper plate drive gear 511, and the rotating lower plate 520 may include a lower plate drive ring gear 521 and a lower plate drive gear 522. Specifically, the rotation drive device 620 is connected to the upper plate drive gear 511, which is in transmission connection with the lower plate drive gear 522 via a transmission rod. The lower plate drive gear 522 meshes with the lower plate drive ring gear 521, so that the rotation drive device 620 drives the seat 100 to rotate and drives the rotating upper plate 510 to rotate relative to the rotating lower plate 520.

[0051] In some embodiments, the unlocking actuator 610 includes two internal stops: an unlocking stop and a locking stop. These two stops can achieve locking in both the unlocked and locked positions. When the unlocking actuator 610 rotates from the locking stop to the unlocking stop and generates a locking signal, the unlocking actuator 610 completes unlocking. When the unlocking actuator 610 rotates from the unlocking stop to the locking stop and generates a locking signal, the unlocking actuator 610 completes locking.

[0052] Based on the above embodiment, as shown in FIG2 , the limit assembly 200 further includes an unlocking pull rope 220 and a locking coil spring 250. The unlocking pull rope 220 is connected between the unlocking drive device 610 and the locking pin 210, and the locking coil spring 250 is connected between the rotating upper disk 510 and the locking pin 210. When the unlocking drive device 610 rotates forward, the unlocking pull rope 220 is pulled by the unlocking drive device 610. The unlocking pull rope 220 overcomes the elastic force of the locking coil spring 250 and drives the locking pin 210 toward the unlocking drive device 610, that is, the locking pin 210 moves toward the inside of the limit hole 512. At this time, the limit assembly 200 is in the first position and is in the unlocked state. When the limiting assembly 200 is in the first position, when the unlocking drive device 610 is reversed, the unlocking drive device 610 releases the unlocking pull rope 220. After the locking pin 210 loses the tension of the unlocking pull rope 220, the locking pin 210 moves toward the outside of the limiting hole 512 under the elastic force of the locking coil spring 250 and remains in a position outside the limiting hole 512. In some embodiments, the limiting assembly 200 includes a fixed rod 230 and a rotating shaft 240 connected between the fixed rod 230 and the rotating upper disk 510. The locking pin 210 is connected to the fixed rod 230. The fixed rod 230 can rotate about the rotating shaft 240 to allow the locking pin 210 to move relative to the limiting hole 512.

[0053] In some embodiments, the vehicle seat system 10 further includes an operating device 710 connected to the control device 400 for user operation. The control device 400 is configured to control the rotation of the seat 100 in response to rotation trigger information output by the user when the operating device 710 is operated. If the operating device 710 stops outputting the rotation trigger information, the control device 400 controls the seat 100 to stop rotating. Optionally, the operating device 710 includes a physical switch, such as a button. When the user presses the operating device 710, the control device 400 controls the seat 100 to rotate. When the user releases the operating device 710, the control device 400 controls the seat 100 to stop rotating. The number of operating devices 710 can be one or two. In embodiments where there is only one operating device 710, the operating device 710 can be rotated or pressed, that is, it can control the rotation direction and rotation angle of the seat 100. In an embodiment where there are two operating devices 710, the two operating devices 710 can respectively control the rotation of the seat 100 in different directions. For example, the first operating device 710 can control the rotation of the seat 100 in one direction of counterclockwise or clockwise, while the second operating device 710 can control the rotation of the seat 100 in the other direction of counterclockwise or clockwise. This can reduce the user's learning curve and enable the user to rotate the seat 100 more quickly. The operating devices 710 can be located below the seat 100 for easier operation.

[0054] FIG3 illustrates a control schematic diagram of an embodiment of the vehicle seat system 10 shown in FIG1 . In some embodiments, the control device 400 is configured to, in response to rotation trigger information, control the unlocking actuator 610 to operate when the stop assembly 200 is in the second position, thereby driving the stop assembly 200 to switch to the first position. Specifically, when the user presses the operating device 710, the unlocking actuator 610 rotates and pulls the lock pin 210 from the outside of the stop hole 512 toward the inside of the stop hole 512, maintaining the lock pin 210 in the inside position of the stop hole 512 (i.e., the stop assembly 200 is in the first position). After the stop assembly 200 is in the first position, the rotation actuator 620 is controlled to operate, driving the seat 100 to rotate. When the lock pin 210 is located inside the stop hole 512, the seat 100 is controlled to rotate, preventing the lock pin 210 from passing through the lock slot 523 during rotation, thereby preventing the lock pin 210 from falling into the lock slot 523. If the operating device stops outputting the rotation trigger information, the rotation drive device 620 is controlled to stop operating, and the unlocking drive device 610 is controlled to operate, causing the limit assembly 200 to switch to the second position. When the user releases the operating device 710, the seat 100 rotates to the target position and stops rotating. Referring to Figure 3, when the limit assembly 200 is in the locked state, the Hall value of the rotation drive device 620 is at "Locked Min"; when the limit assembly 200 is in the unlocked state, the Hall value of the rotation drive device 620 is at "Unlocked Max."

[0055] FIG4 illustrates a control schematic diagram of another embodiment of the vehicle seat system 10 shown in FIG1 . In some embodiments, the vehicle seat system 10 further includes an input device 720 connected to the control device 400 for receiving target rotation angle information input by a user. The control device 400 is configured to determine a target rotation angle for the seat 100 based on the target rotation angle information and control the seat 100 to rotate to the target rotation angle. Optionally, the input device 720 includes a central control screen and a terminal device, which may include a smartphone. The user inputs the target rotation angle information through the input device 720. The target rotation angle information may include the target rotation angle of the seat 100. Specifically, the seat 100 has an initial position. When the seat 100 is in the initial position, the seat 100 faces directly forward of the vehicle body. In this case, the initial position angle of the seat 100 can be defined as 0°. When the seat 100 is at any position within its rotation range, the control device 400 can obtain the angle of the seat 100 at that position. For example, when the seat 100 faces directly backward of the vehicle body, the current angle of the seat 100 is 180°. The target rotation angle information may include a target position. The control device 400 is configured to determine the target rotation angle of the seat 100 based on the angle of the target position relative to the initial position. In one specific embodiment, if the seat 100 is currently facing the front of the vehicle and the user wishes to turn the seat 100 toward the right side of the vehicle, the target angle corresponds to 270°. In other words, the seat 100 stops rotating at 270°. Of course, the rotation direction of the seat 100 can be customized and will not be further explained here.

[0056] In some embodiments, the control device 400 is used to: if the lock slot 523 is located on the rotation path of the limit assembly 200 as the seat 100 rotates to the target rotation angle, control the unlocking drive device 610 to work to drive the limit assembly 200 to switch to the first position, and when the limit assembly 200 is in the first position, control the rotation drive device 620 to work to drive the seat 100 to rotate; if the seat 100 rotates to the target rotation angle, control the rotation drive device 620 to stop working, and control the unlocking drive device 610 to work so that the limit assembly 200 switches to the second position.

[0057] In some embodiments, the lock slot 523 may include a first lock slot 523a and a second lock slot 523b, wherein the first lock slot 523a and the second lock slot 523b are arranged relative to each other. As shown in FIG2 , the first lock slot 523a is located at the 0° position, and the second lock slot 523b is located at the 180° position. When (current rotation angle - 180°) * (target rotation angle - 180°) < 0, it indicates that the current position of the seat 100 is not at 0° or 180° and needs to cross 0° or 180°. At this time, the control lock pin 210 is located on the inner side of the limiting hole 512, and after the seat 100 is controlled to rotate to the target rotation angle, the control lock pin 210 is moved to the outer side of the limiting hole 512.

[0058] In some embodiments, the control device 400 is configured to: if the lock slot 523 is outside the rotation path of the limit assembly 200 as the seat 100 rotates to the target rotation angle, control the unlocking drive device 610 to place the limit assembly 200 in the second position, and when the limit assembly 200 is in the second position, control the rotation drive device 620 to operate to drive the seat 100 to rotate, and control the rotation drive device 620 to stop operating if the seat 100 rotates to the target rotation angle. When the seat 100 does not need to cross 180°, that is, when (current rotation angle - 180°) * (target rotation angle - 180°) ≥ 0, control the lock pin 210 to be located outside the limit hole 512, and control the seat 100 to rotate to the target rotation angle.

[0059] FIG5 illustrates a control schematic diagram of another embodiment of the vehicle seat system 10 shown in FIG1 . FIG6 illustrates a control schematic diagram of another embodiment of the vehicle seat system 10 shown in FIG1 . In some embodiments, the control device 400 is configured to: in response to a user input request to shift gears, if the limit sensor 300 detects that the limit assembly 200 is in the unlocked state, control the limit assembly 200 to switch to the locked state. When the user requests to shift gears, if the limit assembly 200 is in the unlocked state (i.e., when the seat 100 is facing a direction other than the front or rear of the vehicle), the user is prevented from shifting gears, thereby preventing the vehicle from starting and avoiding the safety hazard of starting the vehicle when the seat 100 is not straightened. Referring to FIG5 and FIG6 , if the current angle of the seat 100 prevents shifting out of the P gear, the seat 100 is controlled to rotate, causing the limit assembly 200 to switch from the unlocked state to the locked state. At this point, the operating device 710, i.e., the physical switch, needs to be reset and triggered again before the seat 100 can rotate. It should be noted that the PCMU stands for Power and Chassis Master Unit.

[0060] In some embodiments, the vehicle seat system 10 includes a domain controller 800 connected to the control device 400. In some embodiments, the domain controller 800 includes, but is not limited to, a passive safety domain controller 810, a vehicle body domain controller 840, a power domain controller 820, and an entertainment domain controller 830. In some embodiments, the passive safety domain controller 810 connects the control device 400 to the airbags and is used to control the airbags to be deactivated when the seat 100 faces rearward of the vehicle.

[0061] In some embodiments, the body domain controller 840 is connected to the control device 400 and the input device 720. After the user inputs the target rotation angle information through the input device 720, the body domain controller 840 sends the target rotation angle information to the control device 400, and the control device 400 is used to control the rotation of the seat 100.

[0062] In some embodiments, the power domain controller 820 is connected to the control device 400. After the user requests to shift gears, the power domain controller 820 sends a gear shift request to the control device 400. The control device 400 determines whether the seat 100 has returned to the original position. If the seat 100 has not returned to the original position, the control device 400 sends a seat non-return signal to the power domain controller 820 to prohibit the vehicle from switching to the driving gear and ensure driving safety.

[0063] In some embodiments, the entertainment domain controller 830 connects the control device 400 and the human-machine interface, and the entertainment domain controller 830 adjusts the human-machine interface according to the current position of the seat 100. Optionally, the entertainment domain controller 830 controls a display device to display the current position and angle of the seat 100 to improve the visibility of the rotation of the seat 100.

[0064] In some embodiments, the vehicle seat system 10 includes a fault warning device 910. When a sensor is in a fault state, the control device 400 is configured to control the fault warning device 910 to generate a fault warning message. In some embodiments, the fault warning device 910 includes one or more of a speaker, a display device, and a vibration feedback device. When the rotation drive device sensor is in a fault state, its voltage is abnormal. The control device 400 can determine whether the rotation drive device sensor is in a fault state based on the electrical signal. Furthermore, the control device 400 can determine whether the rotation drive device sensor is in a fault state by determining whether the Hall value of the rotation drive device 620 is normal. If the Hall value of the rotation drive device 620 is normal, the control device 400 determines that the rotation drive device sensor is in a normal operating state. If the Hall value of the rotation drive device 620 is abnormal, the control device 400 determines that the rotation drive device sensor is in a fault state and controls the fault warning device 910 to generate a fault warning message.
