Description

Technical Field

[0001] The present application relates to the technical field of automotive parts, and particularly to a vehicle seat system and a vehicle including the same. Background Art

[0002] With the popularization of automobiles, users' requirements for automotive safety are getting higher and higher. Child seats play an important role in reducing the casualties of children in vehicle collision accidents.

[0003] However, the airbag in the front passenger seat of the vehicle will explode after a collision, which is likely to cause impact injuries to children on the child seat installed on the passenger seat. Summary of the Invention

[0004] The present application provides a vehicle seat system and a vehicle including the same, which can improve the safety of children riding.

[0005] One aspect of the present application provides a vehicle seat system, including:

[0006] A seat rotatably disposed on the vehicle body in the front-back direction;

[0007] A child seat interface disposed on the seat for connecting a child seat;

[0008] A limiting component including a first state and a second state, the limiting component being switchable between the first state and the second state; when the limiting component is in the first state, it is closer to the child seat interface than in the second state to prevent the child seat from being plugged into the child seat interface; when the limiting component is in the second state, the child seat is allowed to be plugged into the child seat interface; when the seat faces the front of the vehicle, the limiting component is in the first state, and when the seat faces the rear of the vehicle, the limiting component is in the second state.

[0009] By setting the limiting component to restrict the installation of the child seat when the seat faces the front of the vehicle, the present application can prevent children on the child seat from being injured by the airbag popping out in the event of a vehicle collision, thereby improving the safety of children riding, having a better protection effect on children, and enhancing the user riding experience.

[0010] Further, it further includes a controller connected to the limiting component and a seat position detection device connected to the controller. The seat position detection device is used to detect the position of the seat, and the controller is used to control the state of the limiting component according to the position of the seat. The controller can control whether the limiting component restricts the plugging of the child seat according to the rotation angle of the seat, with high reliability and simple operation.

[0011] Further, the limiting component further includes a third state. When the seat faces the rear of the vehicle, the limiting component can switch between the second state and the third state; when the child seat interface is not plugged with the child seat, the limiting component is in the second state, and when the child seat interface is plugged with the child seat, the limiting component is in the third state; the controller is configured to determine whether the child seat interface is plugged with the child seat according to the state of the limiting component. In this way, the limiting component can identify the installation state of the child seat and monitor whether the child seat is installed on the seat, enabling the user to timely understand the safety situation of the child seat, so as to prevent the child seat from detaching from the seat during driving and improve safety.

[0012] Further, the seat includes an initial position. When the seat is in the initial position, it faces the front of the vehicle; the seat position detection device is configured to detect the rotation angle of the seat relative to the initial position.

[0013] The controller is configured to control the limiting component to be in the first state when the rotation angle is less than a preset angle; and control the limiting component to be in the second state when the rotation angle is greater than or equal to the preset angle. The seat position detection device determines the direction in which the seat faces by detecting the rotation angle of the seat. When the seat rotates partially forward, the limiting component prevents the installation of the child seat, further enhancing safety.

[0014] Further, it further includes a passive safety domain controller connecting the controller and the airbag. The passive safety domain controller is configured to control the airbag to close when the limiting component is in the third state. When the child seat is plugged into the child seat interface, the airbag is actively closed to prevent the child from being injured by the airbag popping out during a vehicle collision.

[0015] Further, when the limiting component is in the third state, the controller is configured to control the rotation angle to be greater than or equal to the preset angle. When the child seat is plugged into the child seat interface, the seat cannot rotate to an angle less than the preset angle, preventing the user from accidentally operating to rotate the seat to face the front of the vehicle.

[0016] Further, when the limiting component is in the first state, the limiting component is located on the movement path of the child seat being plugged into the child seat interface; when the limiting component is in the second state, the limiting component is away from the child seat interface relative to the first state, avoiding at least part of the movement path. The limiting component restricts the installation of the child seat on the seat by blocking the movement of the child seat, and can more effectively limit the installation of the child seat.

[0017] Further, the limiting component includes a limiting member, the limiting member includes a relative rotating end and a free end, the limiting member can rotate through the rotating end, and the controller is used to control the rotation of the limiting member; the free end of the limiting member when the limiting component is in the first state is closer to the child seat interface than in the second state. By changing the rotation angle of the limiting member to switch the state of the limiting component, the structure is simple and the cost is low.

[0018] Further, the limiting component includes an elastic member, and the elastic member is connected to the rotating end of the limiting member; when the child seat is inserted into the child seat interface, the limiting member is pushed by the child seat and rotates from the second state to the third state, and the elastic member is compressed; when the child seat is detached from the child seat interface, the limiting member is subjected to the restoring force of the elastic member and rotates from the third state to the second state. After the elastic member is compressed, it has a restoring force to restore its original state, which can make the limiting component return from the third state to the second state automatically after the child seat is removed, so as to realize automatic repeated identification of the installation state of the child seat.

[0019] Further, it further includes a sensor connected to the controller, and the sensor is used to detect the rotation angle of the limiting component; the controller is used to determine whether the child seat interface is plugged with the child seat according to the rotation angle of the limiting component. In this way, the rotation angle of the limiting component can be accurately judged to improve the sensitivity of judging the installation state of the child seat.

[0020] Further, the limiting component further includes a limiting member, and the limiting member includes a limiting groove close to the limiting member; the limiting member further includes a limiting portion; when the limiting component is in the first state, the limiting portion is separated from the limiting groove; when the limiting component is in the second state, the limiting portion is located in the limiting groove. The cooperation of the limiting portion and the limiting groove can limit the further rotation of the limiting member after it rotates to the second state, and prevent the limiting member from rotating due to system misjudgment or other reasons when it is in the second state, so as to ensure the stability of the state of the limiting member.

[0021] Further, the limiting component further includes a limiting block, and when the limiting component is in the first state, the limiting component abuts against the limiting block. The limiting block can prevent the limiting member from rotating beyond a preset angle range and ensure the normal operation of the system.

[0022] One aspect of the present application provides a vehicle, including the vehicle seat system described in any one of the above. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The vehicle seat system according to an embodiment of this application includes a seat, a child seat interface and a restricting component. The seat is rotatably disposed on the vehicle body in the front-rear direction. The child seat interface is disposed on the seat for connecting a child seat. The restricting component includes a first state and a second state, and the restricting component can be switched between the first state and the second state; when the restricting component is in the first state, it is closer to the child seat interface than in the second state to prevent the child seat from being plugged into the child seat interface; when the restricting component is in the second state, the child seat is allowed to be plugged into the child seat interface; when the seat faces the front of the vehicle, the restricting component is in the first state, and when the seat faces the rear of the vehicle, the restricting component is in the second state.

[0035] The vehicle seat system provided by this application restricts the installation of a child seat when the seat faces the front of the vehicle, so as to prevent the child on the child seat from being injured by the airbag when the vehicle collides, thereby improving the safety of the child seat, having a better protection effect on children, and enhancing the user's riding experience.

[0036] The vehicle according to an embodiment of this application includes the above vehicle seat system.

[0037] The following will combine with the attached drawings to detail the vehicle seat system of the present application and the vehicle including the same. Without conflict, the features in the following embodiments and implementation manners can be combined with each other.

[0038] Figure 1 The top view of an embodiment of the vehicle seat system 10 of the present application is shown. The vehicle of the embodiment of the present application includes the vehicle seat system 10. Among them, the vehicle includes but is not limited to sedans, SUVs, off-road vehicles or other power-driven non-railborne vehicles; the power source of the vehicle can be fuel or a power battery, and the present application does not limit this here. Usually, airbags are provided at the driver's and front passenger's seats in the front row of the vehicle to effectively protect the personnel in the driver's and front passenger's seats in the front row.

[0039] Figure 2 As shown Figure 1 The system block diagram of the vehicle seat system 10 shown is shown. The vehicle seat system 10 of the embodiment of the present application includes a seat 20, a child seat interface 100 and a limiting component 200. Among them, the seat 20 is rotatably arranged on the vehicle body in the front-back direction. The child seat interface 100 is arranged on the seat 20 and is used to connect the child seat 30. The limiting component 200 includes a first state and a second state, and the limiting component 200 can be switched between the first state and the second state. When the limiting component 200 is in the first state, it is closer to the child seat interface 100 than in the second state to prevent the child seat 30 from being plugged into the child seat interface 100. When the limiting component 200 is in the second state, the child seat 30 is allowed to be plugged into the child seat interface 100. When the seat 20 faces the front of the vehicle, the limiting component 200 is in the first state, and when the seat 20 faces the rear of the vehicle, the limiting component 200 is in the second state.

[0040] The vehicle seat system 10 of the embodiment of the present application restricts the installation of the child seat 30 when the seat 20 faces the front of the vehicle by setting the limiting component 200, so as to prevent the children on the child seat 30 from being injured by the airbag when the vehicle collides, thereby improving the safety of the child seat 30, having a better protection effect on children, and enhancing the user's riding experience.

[0041] In some embodiments, the seat 20 can rotate forward and backward relative to the vehicle about the central axis of the seat 20, and the seat 20 can rotate from facing the front of the vehicle to facing the rear of the vehicle. The rotatable seat 20 can improve the riding comfort of the user and enable the vehicle to have multi-scenario applications and multi-space layouts. In some embodiments, the seat 20 includes an initial position and a rotation position. When the seat 20 is in the initial position, the seat 20 faces directly forward of the vehicle. When the seat 20 faces directly forward of the vehicle, the rotation angle of the rotation position of the seat 20 relative to the initial position is 0°. When the seat 20 faces the left or right side of the vehicle, the rotation angle of the rotation position of the seat 20 relative to the initial position is 90°. When the seat 20 faces directly rearward of the vehicle, the rotation angle of the rotation position of the seat 20 relative to the initial position is 180°. It can be understood that the maximum rotation angle of the rotation position of the seat 20 relative to the initial position can be any angle between 90° and 180°, so that the seat 20 can face the rear of the vehicle, and this application does not make any restrictions. Optionally, the maximum rotation angle can be 90°, 135° or 180°. In some embodiments, the user can adjust the maximum rotation angle by himself to meet different usage requirements of the user, improve the flexibility of the seat 20 and increase the multi-scenario application function of the seat 20. In some embodiments, when the rotation angle is less than the preset angle, the seat 20 faces the front of the vehicle, and the limiting component 200 is in the first state. When the rotation angle is greater than or equal to the preset angle, the seat 20 faces the rear of the vehicle, and the limiting component 200 is in the second state. In some embodiments, the preset angle is 90°.

[0042] Reference Figure 2 , in some embodiments, the vehicle seat system 10 includes a seat driving device 600, and the seat driving device 600 provides power for the rotation of the seat 20 so that the seat 20 rotates between the initial position and the rotation position. Optionally, the seat driving device 600 can be a motor, which runs reliably and has a low cost; of course, the seat driving device 600 can also be other power devices such as a hydraulic transmission device or a pneumatic transmission device, which will not be elaborated here. In other embodiments, the seat 20 needs to be rotated manually by the user or by other external forces, and there is no need to provide the seat driving device 600, which saves cost and space.

[0043] In some embodiments, the seat 20 is a front passenger seat and is rotatably disposed on the vehicle body. In the related art, the proportion of the head weight of children under 15 months old to the body weight is relatively high, and their necks do not have enough strength to support the head. Therefore, it is recommended to use a rear-facing child seat so that when a frontal collision of the vehicle occurs, the necks of children will not be overly stressed and injured. If the child seat is rear-facingly installed on the front passenger seat, the airbag in front of the front passenger seat will pop out during a vehicle collision, resulting in child casualties. The seat 20 in the embodiments of the present application adopts the technical solution of a front passenger seat rotatably disposed on the vehicle body. When the seat 20 faces forward of the vehicle, the child seat 30 cannot be installed on the seat 20. When the seat 20 faces the rear of the vehicle, the child seat 30 is allowed to be installed on the seat 20. In this way, it not only provides convenience for parents to take care of children from the second row forward, but also can rotate the front passenger seat to face the rear of the vehicle to provide a protection effect similar to that of a rear-facing installation for the child seat 30 and provide a safer and more comfortable riding experience for children.

[0044] Optionally, the child seat interface 100 can be disposed at a position below the backrest of the seat 20 near the seat cushion, or at the joint of the seat 20, which is convenient for plugging and matching with the child seat 30. In some embodiments, the child seat interface 100 is an ISO-FIX (International Standards Organisation FIX) interface; correspondingly, the child seat connector matching with the child seat interface 100 is an ISO-FIX connector. The ISO-FIX structure has a firm connection, high safety, a simple structure, is convenient for installing the child seat 30, is conducive to standardized production, reduces production costs, and improves the adaptability of the child seat interface 100. Of course, the child seat interface 100 and the child seat connector can also be other standard structures or non-standard structures. In some embodiments, a part of the child seat interface 100 protrudes away from the seat 20 to form a shape as shown in Figure 1 Figure [not shown]. Specifically, both ends of the child seat interface 100 are fixedly connected to the seat 20, and the middle part of the child seat interface 100 protrudes outward, so that the child seat interface 100 can effectively utilize the internal space of the seat 20 without affecting the original structure of the seat 20. Correspondingly, the seat 20 is provided with a receiving space and an opening for receiving the child seat interface 100, and the protruding part of the child seat interface 100 can extend beyond the opening or be located within the receiving space. In some embodiments, the child seat interface 100 is rod-shaped and has a circular cross-section, which is convenient for installing the child seat 30.

[0045] In some embodiments, the limiting component 200 includes a driving member 260, and the driving member 260 provides power for the movement of the limiting component 200. Optionally, the driving member 260 may be a motor, which has reliable operation and low cost. Of course, the driving member 260 may also be other power devices such as a hydraulic transmission device or a pneumatic transmission device, which will not be elaborated here. In other embodiments, the limiting component 200 needs to move manually by the user or by other external acting forces. In some embodiments, the driving member 260 is an electromagnet, and the limiting component 200 is provided with a magnetic member. When the electromagnet is energized, it has magnetism and generates a magnetic force that can attract the limiting component 200 to move, so that the limiting component 200 switches between the first state and the second state. When the electromagnet is de-energized, it loses magnetism, and the limiting component 200 returns to the first state or the second state. In other embodiments, the rotation of the seat 20 drives the limiting component 200 to move relative to the child seat interface 100. In this way, the driving member 260 for driving the movement of the limiting component 200 may not be provided, saving costs. The connection between the seat 20 and the limiting component 200 may be a chain drive, a belt drive or other drive methods, which is not limited.

[0046] In one embodiment, the limiting component 200 is a stopper. When the limiting component 200 is in the first state, the stopper is located above and / or below the child seat interface 100. At this time, the stopper may or may not be in contact with the child seat interface 100. When the limiting component 200 is in the second state, the stopper is away from the child seat interface 100. In another embodiment, the limiting component 200 is a claw structure. When the limiting component 200 is in the first state, the claw structure is clamped on the child seat interface 100, and part of the claw structure surrounds and covers at least part of the child seat interface 100. When the limiting component 200 is in the second state, the claw structure disengages from the child seat interface 100. In yet another embodiment, the limiting component 200 is a cover that can move relative to the child seat interface 100, and the cover is provided at the opening of the accommodation space of the seat 20. When the limiting component 200 is in the first state, the cover covers the opening of the accommodation space. When the limiting component 200 is in the second state, the cover is opened, and at least part of the child seat interface 100 is exposed.

[0047] In some embodiments, when the limiting component 200 is in the first state, the limiting component 200 is located on the movement path of the child seat 30 inserted into the child seat interface 100; when the limiting component 200 is in the second state, the limiting component 200 is away from the child seat interface 100 relative to the first state, avoiding at least part of the movement path. In this way, the installation of the child seat 30 can be more effectively restricted. It can be understood that the movement path of the child seat 30 inserted into the child seat interface 100 is from the outside of the seat 20 towards the inside of the seat 20. In some embodiments, the limiting component 200 can be a stopper provided between the child seat interface 100 and the seat 20, and the stopper can move in the up-down direction or in the horizontal direction. When the limiting component 200 is in the first state, the stopper is located between the child seat interface 100 and the seat 20; when the limiting component 200 is in the second state, the stopper moves to a position away from the movement path, such as above or below the child seat interface 100. In some embodiments, the child seat interface 100 protrudes to form a receiving portion 110, and when the limiting component 200 is in the first state, it is located in the receiving portion 110; when the limiting component 200 is in the second state, at least part of the limiting component 200 is located outside the receiving portion 110.

[0048] Figure 3 Shown as Figure 1 The cross-sectional view of the limiting component 200 shown in the first state. Figure 4 Shown as Figure 1 The top view of the limiting component 200 shown in the second state. Figure 5 Shown as Figure 1 The cross-sectional view of the limiting component 200 shown in the second state. Further, the limiting component 200 includes a limiting member 210, the limiting member 210 includes opposite rotating ends 211 and free ends 212, and the limiting member 210 can rotate through the rotating end 211. In some embodiments, the limiting member 210 can rotate in the up-down direction. In other embodiments, the limiting member 210 can rotate in the horizontal direction. Such as Figure 3 and Figure 5As shown, when the limiting component 200 is in the first state, the free end 212 of the limiting member 230 is closer to the child seat interface 100 than in the second state. In some embodiments, the limiting component 200 includes a rotating shaft 250. The rotating shaft 250 is fixed to the seat 20 and passes through the rotating end 211, enabling the limiting member 210 to rotate around the rotating shaft 250 so that the limiting component 200 can switch between the first state and the second state. In some embodiments, the rotating shaft 250 is arranged parallel to the child seat interface 100, enabling the limiting member 210 to rotate around the rotating shaft 250 in the up and down direction. By changing the rotation angle of the limiting member 210, the limiting member 210 is moved away from or closer to the child seat interface 100 to switch the state of the limiting component 200. The structure is simple and the cost is low. In some embodiments, the limiting member 210 is a gear lever, with one end being the rotating end 211 and the other end being the free end 212. In some embodiments, the center of the cross-section of the rotating shaft 250 is located on the central axis of the limiting member 210. Further, as Figure 3 shown, when the limiting component 200 is in the first state, the central axis Y-Y of the limiting member 210 coincides with the connection line X-X between the cross-section center of the child seat interface 100 and the cross-section center of the rotating shaft 250; as Figure 5 shown, when the limiting component 200 is in the second state, there is an included angle between the central axis Y-Y of the limiting member 210 and the connection line X-X between the cross-section center of the child seat interface 100 and the cross-section center of the rotating shaft 250, and this included angle is the rotation angle α. In some embodiments, the range of the rotation angle α is 0° to 90°. Optionally, the rotation angle α can be 30°, 45° or 60°. It should be noted that the rotation angle α needs to be determined comprehensively based on the distance between the rotating shaft 250 and the child seat interface 100 and the length and width of the limiting member 210, so that after the limiting component 200 switches from the first state to the second state, the child seat 30 can be inserted into the child seat interface 100 without being blocked by the limiting component 200. In some embodiments, the limiting member 210 rotates clockwise to switch the limiting component 200 from the first state to the second state.

[0049] Figure 6 As shown is Figure 1The cross-sectional view of the limiting component 200 in the third state is shown. In some embodiments, the limiting component 200 includes a third state. When the seat 20 faces the rear of the vehicle, the limiting component 200 can switch between the second state and the third state. When the child seat interface 100 is not plugged with the child seat 30, the limiting component 200 is in the second state. When the child seat interface 100 is plugged with the child seat 30, the limiting component 200 is in the third state. When the child seat 30 is inserted into the child seat interface 100, the limiting component 200 switches from the second state to the third state. When the child seat 30 is inserted into the child seat interface 100, the limiting component 200 moves from the second state to the third state under the action of the child seat 30, and the child seat 30 mechanically triggers the limiting component 200 to move from the second state to the third state. When the child seat 30 is pulled out from the child seat interface 100, the limiting component 200 switches from the third state to the second state. Further, as Figure 6 shown, when the limiting component 200 is in the third state, there is an included angle between the central axis Y-Y of the limiting member 210 and the line X-X connecting the cross-sectional center of the child seat interface 100 and the cross-sectional center of the rotating shaft 250, and this included angle is the rotation angle β. In some embodiments, the range of the rotation angle β is 0° to 90°, and it is greater than the rotation angle α. In some embodiments, the limiting member 210 rotates clockwise to cause the limiting component 200 to switch from the second state to the third state.

[0050] Reference Figure 3 , in some embodiments, the connection between the upper surface of the limiting member 210 and the side surface close to the child seat interface 100 and / or the connection between the lower surface of the limiting member 210 and the side surface close to the child seat interface 100 are in arc transition. During the process of plugging the child seat 30 into the child seat interface 100, the limiting member 210 is pushed by the child seat 30, and the child seat 30 may abut against the edge of the limiting member 210, which helps to make the process of plugging the child seat 30 into the child seat interface 100 smoother and more fluent.

[0051] In some embodiments, the limiting component 200 includes an elastic member 220, and the elastic member 220 is connected to the rotating end 211 of the limiting member 210. When the child seat 30 is plugged into the child seat interface 100, the limiting member 210 is pushed by the child seat 30 and rotates from the second state to the third state, and the elastic member 220 is compressed; when the child seat 30 is detached from the child seat interface 100, the limiting member 210 is subjected to the restoring force of the elastic member 220 and rotates from the third state to the second state. In some embodiments, one end of the elastic member 220 is connected to the rotating shaft 250, and the other end of the elastic member 220 is connected to the limiting member 210. Further, one end of the elastic member 220 is connected to the rotating shaft 250, and the other end of the elastic member 220 is connected to the rotating end 211. Optionally, the elastic member 220 is a coil spring.

[0052] Reference Figure 3 、 Figure 5 and Figure 6 , in some embodiments, the limiting component 200 includes a limiting member 230. Further, the limiting member 230 includes a limiting groove 231 near the limiting member 210, and the limiting member 210 includes a limiting portion 213. As Figure 3 and Figure 6 shown, when the limiting component 200 is in the first state or the third state, the limiting portion 213 disengages from the limiting groove 231; as Figure 5 shown, when the limiting component 200 is in the second state, the limiting portion 213 is located in the limiting groove 231. The cooperation between the limiting portion 213 and the limiting groove 231 can limit the further rotation of the limiting member 230 after it rotates to the second state, preventing the limiting member 210 from rotating due to system misjudgment or other reasons when it is in the second state, so as to ensure the stability of the state of the limiting member 210. In some embodiments, the limiting portion 213 is spherical with a smooth surface, and correspondingly, the limiting groove 231 is in the shape of a concave spherical bowl.

[0053] In some embodiments, the limiting component 200 includes a limiting block 240. When the limiting component 200 is in the first state, the limiting component 200 abuts against the limiting block 240. The limiting block 240 can prevent the limiting member 230 from rotating beyond a preset angular range, ensuring the normal operation of the vehicle seat system 10. In some embodiments, reference Figure 3 , the limiting block 240 is located above the limiting member 210, and the lower surface of the limiting block 240 is parallel to the line X-X connecting the cross-sectional centers of the child seat interface 100 and the rotating shaft 250, so as to prevent the limiting member 230 from further rotating after rotating to the first state.

[0054] Reference Figure 2, in some embodiments, the vehicle seat system 10 includes a controller 300 connected to a restraint assembly 200. The controller 300 is configured to control the states of the seat 20 and the restraint assembly 200. Further, the controller 300 is configured to control the rotation of the seat 20 and the rotation of the restraint 210. In some embodiments, the controller 300 is configured to determine whether a child seat interface 100 is plugged with a child seat 30 according to whether the restraint assembly 200 is in a third state. If the restraint assembly 200 is in the third state, it is determined that the child seat interface 100 is plugged with the child seat 30; otherwise, it is determined that the child seat interface 100 is not plugged with the child seat 30. Optionally, the controller 300 may be an ECU (Electronic Control Unit). In some embodiments, when the restraint assembly 200 is in the third state, the controller 300 is configured to control the rotation angle to be greater than or equal to a preset angle to prevent the user from accidentally rotating the seat to face the front of the vehicle. Thus, when the seat 20 faces the rear of the vehicle and the child seat 30 is inserted into the child seat interface 100, the controller 300 controls the seat 20 to remain in the rear-facing state. In some other embodiments, when the restraint assembly 200 is in the third state, the controller 300 outputs a seat rotation prohibition signal to a seat driving device 600 to prevent the seat 20 from rotating.

[0055] In some embodiments, the vehicle seat system 10 includes a seat position detection device 410 and a sensor 420 connected to the controller 300. The seat position detection device 410 is configured to detect the position of the seat 20, and the controller 300 is configured to control the state of the restraint assembly 200 according to the position of the seat 20. In some embodiments, the seat position detection device 410 is configured to detect the rotation angle of the seat 20 relative to the initial position, and the controller 300 is configured to control the state of the restraint assembly 200 according to the rotation angle of the seat 20. If the rotation angle is less than the preset angle, it indicates that the seat 20 faces the front of the vehicle, and the controller 300 controls the restraint assembly 200 to be in the first state; if the rotation angle is greater than the preset angle, it indicates that the seat 20 faces the rear of the vehicle; if the rotation angle is equal to the preset angle, it indicates that the seat 20 faces the right side of the vehicle, and the controller 300 controls the restraint assembly 200 to be in the second state.

[0056] The sensor 420 is configured to detect the rotation angle of the restraint assembly 200. The controller 300 determines whether the child seat interface 100 is plugged with the child seat 30 according to the rotation angle of the restraint assembly 200. In some embodiments, such as Figure 3As shown, when the limiting component 200 is in the first state, the central axis Y-Y of the limiting member 210 coincides with the line X-X connecting the cross-sectional center of the child seat interface 100 and the cross-sectional center of the rotating shaft 250. When the sensor 420 detects that the included angle between the central axis Y-Y of the limiting member 210 and the line X-X connecting the cross-sectional center of the child seat interface 100 and the cross-sectional center of the rotating shaft 250 is the set rotation angle α, the controller 300 determines that the child seat 30 is not plugged into the child seat interface 100; when the sensor 420 detects that the included angle between the central axis Y-Y of the limiting member 210 and the line X-X connecting the cross-sectional center of the child seat interface 100 and the cross-sectional center of the rotating shaft 250 is the rotation angle β, the controller 300 determines that the child seat 30 is plugged into the child seat interface 100.

Further, the sensor 420 includes a Hall sensor, and the Hall sensor is disposed inside the motor to obtain the rotation angle of the limiting component 200. The rotation angle of the motor corresponds to the motor Hall value, and the sensor 420 outputs the motor Hall value to the controller 300. The controller 300 determines the installation state of the child seat 30 according to the relationship between the motor Hall value and the set Hall value.

[0058] In some embodiments, the seat driving device 600 is connected to the seat 20 and the controller 300, and the controller 300 is configured to control the seat driving device 600 to drive the seat 20 to rotate. Further, the seat position detecting device 410 outputs the rotation angle of the seat 20 to the controller 300. The controller 300 determines the position of the seat 20 according to the relationship between the rotation angle and the preset angle, and combines the motor Hall value output by the sensor 420 to determine the state of the limiting component 200 and the installation state of the child seat 30.

[0059] In some embodiments, the vehicle seat system 10 includes a fault reminder device 700. When the sensor 420 is in a fault state, the controller 300 is configured to control the fault reminder device 700 to generate a fault reminder message. In some embodiments, the fault reminder device 700 includes one or several of a speaker, a display device, and a vibration feedback device. The fault state of the sensor 420 includes, but is not limited to, a short circuit of the sensor 420 and an open circuit of the sensor 420. When the sensor 420 is in a fault state, its voltage is abnormal, and the controller 300 can determine whether the sensor is in a fault state through an electrical signal. Further, the controller 300 can determine whether the sensor 420 is in a fault state by judging whether the motor Hall value is normal. If the motor Hall value is normal, the controller 300 determines that the sensor 420 is in a normal operating state. If the motor Hall value is abnormal, the controller 300 determines that the sensor 420 is in a fault state and controls the fault reminder device 700 to generate a fault reminder message.

[0091] In some embodiments, it is determined whether the child seat 30 is installed on the seat 20, that is, whether the limiting component 200 is in the third state. In some embodiments, if the limiting component 200 is in the third state, the child seat 30 is installed on the seat 20, and a seat rotation prohibition signal is output to the seat driving device 600 to control the seat driving device 600 to prevent the seat 20 from rotating or to control the rotation angle of the seat 20 relative to the initial position to be greater than or equal to a preset angle. At this time, the domain controller 500 receives the signal that the child seat 30 has been installed and controls the states of relevant devices and components.
