[0058] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0059] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0060] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "above" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways, and the spatial relative descriptions used herein will be interpreted accordingly.

[0061] In the following description, the positional relationship of the vehicle during normal driving is used as a reference. The position of the front of the vehicle is called the "front end", the position of the rear of the vehicle is called the "rear end", the direction from the front to the rear of the vehicle is called the "front-rear direction", and based on the aforementioned front-rear direction, the two sides of the vehicle's width direction are "left side" and "right side" respectively. The direction from the left side of the vehicle to the right side is called the "left-right direction", and the direction from the chassis of the vehicle to the roof is called the "height direction". The front-rear direction, left-right direction and height direction are perpendicular to each other.

[0062] refer to Figures 1 to 22 This application provides a vehicle seat according to some embodiments. The seat provided in this application includes a base 20, a seat body 10, and a first drive assembly. The seat body 10 is disposed above the base 20. The first drive assembly is disposed between the base 20 and the seat body 10. The first drive assembly includes a rocker arm structure 30 and a first connector 40. The rocker arm structure 30 includes a first rocker arm 31 and a second rocker arm 32 respectively disposed on both sides of a first direction Y. The first rocker arm 31 is rotatably connected to the base 20 about a first axis X1 and includes a first connecting portion 311 rotatably connected to the seat body 10. The second rocker arm 32 is rotatably connected to the base 20 about a second axis X2 and includes a second connecting portion 321 rotatably connected to the seat body 10. The first axis X1 and the second axis X2 are both parallel to the second direction X and located in the same axial plane, and the second direction X is perpendicular to the first direction Y. The first end of the first connecting member 40 is rotatably connected to the first rocker arm 31, and the second end of the first connecting member 40 is rotatably connected to the second rocker arm 32. The first end and the second end of the first connecting member 40 are located on opposite sides of the axial plane in the height direction Z. For example, in... Figure 1 and Figure 2 In the illustrated embodiment, the first end of the first connector 40 is located on the lower side of the axial plane, and the second end of the first connector 40 is located on the upper side of the axial plane. In other embodiments not shown in the figures, the first end of the first connector 40 may be located on the upper side of the axial plane, and the second end of the first connector 40 may be located on the lower side of the axial plane.

[0063] Figure 1 and Figure 2 The diagram shown is a structural schematic of a seat according to a first embodiment of this application. Referring to the seat of this first embodiment, the seat of this application includes a seat body 10 and a backrest, the backrest being rotatably connected to the seat body 10 to adjust the angle of the backrest relative to the seat body. The seat body 10 includes a seat frame 13.

[0064] The base 20 is located at the bottom of the seat and can be relatively fixedly mounted on the vehicle floor or relatively movable. For example, in some embodiments, the base 20 is configured to be movable on the vehicle floor in the fore-and-aft direction. In this embodiment, the seat body 10 is rotatably connected to the base 20, and the connection to the base 20 is achieved through the rocker arm structure 30 of the first drive assembly. The rocker arm structure 30 includes a first rocker arm 31 and a second rocker arm 32 respectively disposed on both sides of the first direction Y. Figure 1 and Figure 2 In the illustrated embodiment, the first direction Y is the left-right direction of the vehicle; in other embodiments not shown in the figures, the first direction Y can also be the front-back direction of the vehicle, in which case the first rocker arm and the second rocker arm are respectively disposed on the front and back sides.

[0065] refer to Figure 1 and Figure 2 The first rocker arm 31 is rotatably connected to the base 20 about a first axis X1 and includes a first connecting portion 311. When the first rocker arm 31 rotates about the first axis X1, it drives the first connecting portion 311 to rotate synchronously about the first axis X1, thereby driving the seat body 10 connected to the first connecting portion 311 to rotate. Similarly, the second rocker arm 32 is rotatably connected to the base 20 about a second axis X2 and includes a second connecting portion 321. When the second rocker arm 32 rotates about the second axis X2, it drives the seat body 10 connected to the second connecting portion 321 to rotate. Both the first axis X1 and the second axis X2 are parallel to the second direction X and perpendicular to the first direction Y. Specifically... Figure 1 and Figure 2 In the illustrated embodiment, the second direction X is the forward and backward direction of the vehicle.

[0066] The seat in this embodiment utilizes the two ends of the first connector 40 to be rotatably connected to the first rocker arm 31 and the second rocker arm 32, respectively. When the seat requires anti-rocking functionality, the first connector 40 acts as a telescopic drive to drive the coordinated rotation of the first rocker arm 31 and the second rocker arm 32. When anti-rocking functionality is not required, the first connector 40 acts as a connecting rod to reduce costs. In other words, the seat in this embodiment, by providing the first rocker arm 31, the second rocker arm 32, and the first connector 40 for connecting them, allows for the selection of a suitable first connector based on different needs during seat development, without altering other aspects of the seat's structure, thus reducing development costs.

[0067] refer to Figures 1 to 5 In some embodiments, the first connector 40 includes a telescopic drive member, which is telescopically configured between a first end and a second end to drive the first rocker arm 31 and the second rocker arm 32 to rotate.

[0068] Specifically, from 1 to Figure 5 In the first embodiment shown, the first connecting member 40 is a telescopic drive member, and its two ends are telescopically configured. Thus, the two ends of the telescopic drive member are rotatably connected to the first rocker arm 31 and the second rocker arm 32, respectively, and the telescopic configuration of the two ends of the first connecting member 40 enables rotational drive of the first rocker arm 31 and the second rocker arm 32. This allows the seat body 10 to swing around an axis extending in the second direction X when the first rocker arm 31 and the second rocker arm 32 rotate, thereby achieving a rocking reduction function. For example, when the second direction X is the forward / backward direction of the vehicle, such as... Figure 4 and Figure 5 As shown, the seat body 10 can swing about an axis in the front-to-back direction, so that when the vehicle is turning, the swing of the seat body 10 can be controlled to resist inertial forces and thus improve passenger comfort. Alternatively, in an embodiment not shown in the figures, when the second direction X is the left-to-right direction of the vehicle, the seat body 10 can swing about an axis in the left-to-right direction, so that when the vehicle accelerates or decelerates, the swing of the seat body 10 can be controlled to resist inertial forces and thus improve passenger comfort.

[0069] In some embodiments, reference Figures 1 to 5 The telescopic drive component includes a lead screw motor. The lead screw motor includes a motor, a lead screw, and a nut fitted onto the lead screw. Driven by the motor, the lead screw rotates around its own axis. The nut engages with the lead screw to move linearly along the lead screw, allowing the nut to be movably positioned relative to the motor. In this way, the motor is connected to the second rocker arm 32, and the nut is connected to the first rocker arm 31.

[0070] In other embodiments, reference is made to... Figure 13 and Figure 14 The telescopic drive component includes a dual-screw motor. The dual-screw motor includes a motor body 43, a first housing 41, a first screw 42 rotatable relative to the first housing 41, a second housing, a second screw rotatable relative to the second housing, a first nut 44 sleeved on the first screw 42, and a second nut sleeved on the second screw. One of the first nut 44 and the first housing 41 is connected to the first rocker arm 31, and the other is connected to the second rocker arm 32. Similarly, one of the second nut and the second housing is connected to the first rocker arm 31, and the other is connected to the second rocker arm 32.

[0071] Specifically, in some embodiments, the motor shaft 431 of the motor body 43 of the dual lead screw motor is connected to the first lead screw 42 via a transmission assembly (e.g., a worm gear assembly) disposed within the first housing 41 to drive the first lead screw 42 to rotate. A first nut 44 engages with the first lead screw 42 to perform linear motion along the first lead screw 42. Similarly, the motor body 43 is also connected to the second lead screw via a transmission assembly disposed within the second housing to drive the second lead screw to rotate. A second nut engages with the second lead screw to perform linear motion along the second lead screw.

[0072] By using a dual-screw motor to drive the first rocker arm 31 and the second rocker arm 32 to rotate, the stability of operation is improved.

[0073] Specifically, in Figure 14 In the illustrated embodiment, the first nut 44 is connected to the first rocker arm 31, the first housing 41 is connected to the second rocker arm 32, the second nut is connected to the first rocker arm 31, and the second housing is connected to the second rocker arm 32. The connection positions of the first nut 44 and the first rocker arm 31 are different from those of the second nut and the first rocker arm 31 to distribute the force. Preferably, the first nut is connected to the front end of the first rocker arm 31, and the second nut is connected to the rear end of the first rocker arm 31.

[0074] refer to Figure 1 and Figure 2 In some embodiments, the first rocker arm further includes a third connecting portion 312, the second rocker arm 32 further includes a fourth connecting portion 322, and the first drive assembly further includes a second connecting member 50. The first end of the second connecting member 50 is rotatably connected to the third connecting portion 312, and the second end of the second connecting member 50 is rotatably connected to the fourth connecting portion 322.

[0075] The second connector 50 is located on the same side of the axial plane. In some embodiments, in Figure 1 and Figure 2 In the first embodiment shown, the second connector 50 is located on the lower side of the axial plane. For example... Figure 2 As shown, both the third connecting part 312 and the fourth connecting part 322 are located on the lower side of the axial plane.

[0076] In other embodiments not shown in the accompanying drawings, the second connector 50 is located on the upper side of the axial plane.

[0077] In some embodiments, the first rocker arm 31 rotates relative to the base 20 about a first axis X1 extending along the second direction X. During the rotation of the first rocker arm 31, the positions of the first connecting portion 311 and the third connecting portion 312 on the first rocker arm 31 change in the height direction. Based on this, by using a second connecting member 50 to connect the first rocker arm 31 and the second rocker arm 32, the second connecting member 50 can be modified according to different needs to improve the vibration reduction performance in the height direction. For example, in Figures 1 to 5 The first embodiment shown and in Figure 15 and Figure 16 In the fourth embodiment shown, the second connector 50 includes a shock absorber 51. When the vehicle encounters bumps in the height direction while traveling, the shock absorber functions to isolate the vibrations, preventing passengers from experiencing severe jolts and further improving the riding experience. For example, in... Figure 11 and Figure 12 The second embodiment shown andFigure 13 and Figure 14 In the third embodiment shown, the second connector 50 includes a shock absorber 51 and an elastic element 52 sleeved on the shock absorber 51. The elastic element 52 may be a spring, sleeved on the shock absorber 51 to absorb vibrations in the height direction. This arrangement of the shock absorber 51 and elastic element 52, extending substantially in the first direction Y, to provide height-direction damping reduces the space occupied in the seat height direction, making it particularly suitable for passenger vehicles with limited height space. For example, in... Figure 17 and Figure 18 In the fifth embodiment shown, the second connector 50 includes a vibration damping motor 53. The vibration damping motor 53 is connected between the third connector 312 and the fourth connector 322 to achieve active vibration damping in the height direction, further enhancing the vibration damping performance in the height direction.

[0078] Of course, in order to reduce costs, in such Figure 19 and Figure 20 In the sixth embodiment shown, the second connector 50 includes a connecting rod 54. In this case, the second connector 50 can only perform the connection function and does not have a vibration damping function.

[0079] like Figure 2 and Figure 6 As shown, the first rocker arm 31 and the second rocker arm 32 change their relationship with the seat body 10 in the first direction Y during movement, thus requiring an open degree of freedom in the first direction Y on one side. In some embodiments, the second connecting portion 321 of the second rocker arm 32 is rotatably connected to the seat body 10 via a third connecting member.

[0080] like Figures 1 to 6 As shown, in the first embodiment, the third connecting member includes a connecting rod 70. The upper end of the connecting rod 70 is connected to the second rocker arm 32, and the lower end of the connecting rod 70 is connected to the seat body 10, specifically to the second bracket 12 of the seat body 10. In a modified embodiment of the first embodiment, as... Figure 7 As shown, when the second bracket 12 is relatively small in the height direction, the lower end of the connecting rod 70 is connected to the second rocker arm 32, and the upper end of the connecting rod 70 is connected to the seat body 10.

[0081] like Figure 8 As shown, in some embodiments, the seat body 10 has an elongated hole 121. The third connector includes a connecting shaft that passes through and is movable relative to the elongated hole 121, and the second connecting portion 321 of the second rocker arm 32 is rotatably connected to the connecting shaft. In this way, the connecting shaft can move along the elongated hole 121 to release the degree of freedom in the first direction Y, thereby driving the seat body to rotate.

[0082] Specifically, the elongated hole 121 is provided on the second bracket 12 of the seat body 10.

[0083] like Figure 15 and Figure 16 As shown, in the fourth embodiment, the first connector 40 includes a connecting rod. The first drive assembly also includes a second connector 50, the first end of which is rotatably connected to the first rocker arm 31, the second end of which is rotatably connected to the second rocker arm 32, and the second connector 50 includes a shock absorber 51.

[0084] In other words, in the fourth embodiment, the cost is reduced by setting the first connector 40 as a non-retractable connecting rod. Furthermore, the second connector 50 is set as a shock absorber 51, thus enabling the seat in the fourth embodiment to have height-direction vibration damping functionality.

[0085] In some embodiments, the first rocker arm 31 further includes a first rocker arm shaft 310. The first rocker arm shaft 310 extends along a first axis X1 and is rotatably connected to the base 20, and a first connecting portion 311 is fixedly disposed on the first rocker arm shaft 310. The second rocker arm 32 further includes a second rocker arm shaft 320, which extends along a second axis X2 and is rotatably connected to the base 20, and a second connecting portion 321 is fixedly disposed on the second rocker arm shaft 320.

[0086] In some embodiments, the seat further includes a second drive assembly disposed between the seat body 10 and the base 20, the second drive assembly being configured to drive the seat body 10 to move up and down in the height direction Z. When the vehicle encounters a ground protrusion and moves upward, the second drive assembly is compressed to lower the seat body 10. When the vehicle encounters a ground depression and moves downward, the second drive assembly is controlled to raise the seat body 10 to maintain height and support.

[0087] In some embodiments, the second drive assembly includes a gas spring 60. The first drive assembly also includes a second connector 50. A first end of the second connector 50 is rotatably connected to a first rocker arm 31, and a second end of the second connector 50 is rotatably connected to a second rocker arm 32. The second connector 50 also includes a shock absorber 51.

[0088] refer to Figure 17 and Figure 18 In other embodiments, the second drive assembly includes a vibration damping motor 53, a first end of which is rotatably connected to a first rocker arm 31, and a second end of which is rotatably connected to a second rocker arm 32. Figure 17 and Figure 18 In the illustrated embodiment, active vibration reduction in the height direction Z is achieved by making the second drive component a vibration damping motor 53 disposed between the first rocker arm 31 and the second rocker arm 32.

[0089] Specifically, such as Figure 17 andFigure 18 As shown, the first end of the vibration damping motor 53 is rotatably connected to the third connecting part 312 of the first rocker arm 31, and the second end of the vibration damping motor 53 is rotatably connected to the fourth connecting part 322 of the second rocker arm 32.

[0090] refer to Figure 21 and Figure 22 In some embodiments, the seat further includes a third drive assembly. The third drive assembly is configured to drive the seat body 10 to oscillate about an axis parallel to the first direction Y.

[0091] In some embodiments, the third drive assembly is configured to drive the seat body 10 to swing about an axis parallel to the first direction Y, that is, the seat body 10 swings back and forth about an axis in the left-right direction. When the vehicle accelerates, the seat body is controlled to rotate so that the front end swings downward to provide a counterforce to the passenger and alleviate the impact of inertia on the passenger; when the vehicle decelerates, the seat body is controlled to rotate so that the front end swings upward to provide a counterforce to the passenger and alleviate the discomfort caused by the inertia causing the passenger to lurch forward.

[0092] This application also provides a vehicle including the aforementioned seat.

[0093] The following is based on Figures 1 to 22 The technical solutions of seven specific embodiments of this application will be described in detail.

[0094] In the following descriptions of the embodiments, the first direction Y is the left-right direction, and the second direction X is the front-back direction.

[0095] Figures 1 to 10 A structural schematic diagram of the seat according to the first embodiment of this application is shown.

[0096] like Figure 1 As shown, the seat in the first embodiment includes a seat body 10, a base 20, a first drive assembly, and a second drive assembly. The first drive assembly includes a rocker arm structure 30, a first connector 40, and a second connector 50. The second drive assembly includes a gas spring 60. The base 20 and the seat body 10 are spaced apart in the height direction Z, and both the first drive assembly and the second drive assembly are disposed between the base 20 and the seat body 10.

[0097] like Figure 2 As shown, the seat body 10 includes a seat frame 13 and a first bracket 11 and a second bracket 12 respectively disposed on the left and right sides of the seat frame 13.

[0098] The rocker arm structure 30 includes a first rocker arm 31 and a second rocker arm 32 respectively disposed on the left and right sides. The first rocker arm 31 includes a first rocker arm shaft 310 and a first connecting part 311, a third connecting part 312, and a fifth connecting part 313 fixedly disposed on the first rocker arm shaft 310. The first rocker arm shaft 310 is a shaft structure extending along a first axis X1. The first connecting part 311 includes two support arm structures respectively disposed at the front and rear ends of the first rocker arm shaft 310. Both support arm structures are disposed on the left side of the first rocker arm shaft 310 and are rotatably connected to the first bracket 11. The third connecting part 312 is disposed at the front end of the first rocker arm shaft 310 and located on the lower side. The fifth connecting part 313 is disposed at the rear end of the first rocker arm shaft 310 and located on the lower side. The second rocker arm 32 includes a second rocker arm shaft 320 and a second connecting part 321, a fourth connecting part 322, and a sixth connecting part 323 fixedly disposed on the second rocker arm shaft 320. The second connecting part 321 includes two support arm structures respectively disposed at the front and rear ends of the second rocker arm shaft 320. Both support arm structures are disposed on the right side of the second rocker arm shaft 320 and are rotatably connected to the second bracket 12. The fourth connecting part 322 is disposed at the front end of the second rocker arm shaft 320 and located on the lower side. The sixth connecting part 323 is disposed at the rear end of the second rocker arm shaft 320 and located on the upper side.

[0099] like Figure 3 As shown, the first rocker arm shaft 310 passes through the shaft hole on the base 20 to be rotatably connected to the base 20, and the second rocker arm shaft 320 passes through the shaft hole on the base 20 to be rotatably connected to the base 20.

[0100] like Figure 2 As shown, the first connecting member 40 is a lead screw motor. The two ends of the lead screw motor are connected to the sixth connecting part 323 of the second rocker arm 32 and the fifth connecting part 313 of the first rocker arm 31, respectively. The fifth connecting part 313 and the sixth connecting part 323 are located on both sides of the axial plane, so that the extension direction of the lead screw motor passes through the axial plane and is inclined.

[0101] The second connecting member 50 is a vibration damper 51. Both ends of the second connecting member 50 are rotatably connected to the third connecting portion 312 and the fourth connecting portion 322, respectively. The vibration damper 51 can be, for example, a hydraulic vibration damper, which absorbs vibration through the extension and retraction of a piston. By utilizing a vibration damper 51 positioned approximately in the first direction Y to dissipate vibration in the height direction Z, the space occupied in the height direction Z is reduced compared to positioning a vibration damper in the height direction Z itself.

[0102] like Figure 2 As shown, in this embodiment, the gas spring 60 is connected between the base 20 and the seat body 10.

[0103] When a vehicle is in motion, if the driver makes a steering maneuver or encounters minor lateral bumps, the seat will inevitably sway from side to side due to centrifugal force, affecting passenger comfort and safety. For example... Figures 3 to 5 As shown, centrifugal force can be resisted by tilting the seat to the left or right.

[0104] When a vehicle is in motion, the road surface is often not perfectly smooth, but contains uneven conditions such as potholes, gravel, and speed bumps, causing the vehicle to bounce up and down. This bouncing can affect passenger comfort and safety. Figure 9 and Figure 10 As shown, the gas spring 60 can be controlled to extend and retract vertically. When the vehicle encounters a bump in the ground and moves upward, the gas spring 60 is compressed to absorb the impact. When the vehicle encounters a pothole and moves downward, the gas spring is extended to maintain height and support.

[0105] In the first embodiment, a lead screw motor drives the rocker arm structure to tilt the seat body to the left or right to reduce the impact of centrifugal force on passenger comfort. Furthermore, a shock absorber 51 reduces vibration in the height direction Z, and a gas spring 60 further controls the height of the seat body to cope with bumpy road conditions.

[0106] Figure 11 and Figure 12 A structural schematic diagram of the seat according to the second embodiment of this application is shown.

[0107] The structure of the seat in the second embodiment is basically the same as that in the first embodiment, except that in the second embodiment, the second connecting member 50 includes a shock absorber 51 and an elastic element 52 sleeved on the shock absorber 51. The elastic element 52 can be a spring. The gas spring provided in the height direction Z is omitted.

[0108] The seat’s structural compactness is improved by using an elastic element 52 that is coaxially arranged with the damper 51 to achieve vibration reduction in the height direction Z.

[0109] Other parts that are the same as in the first embodiment will not be described again.

[0110] Figure 13 and Figure 14 A structural schematic diagram of the seat according to the third embodiment of this application is shown.

[0111] The structure of the seat in the third embodiment is basically the same as that in the second embodiment, with the main difference being that in the third embodiment, the first connecting member 40 is a dual-screw motor, and includes a first screw and a second screw arranged in parallel. The two ends of the first screw are connected to the first rocker arm 31 and the second rocker arm 32, respectively, and the two ends of the second screw are connected to the first rocker arm 31 and the second rocker arm 32, respectively. This arrangement can distribute the force and improve the structural stability.

[0112] Figure 15 and Figure 16 A structural schematic diagram of the seat according to the fourth embodiment of this application is shown.

[0113] The structure of the seat in the fourth embodiment is basically the same as that in the first embodiment, the main difference being that in the fourth embodiment, the first connecting member 40 is a connecting rod. In this embodiment, because the first connecting member 40 is a connecting rod, the seat cannot achieve left or right tilting movements. Conversely, because the first connecting member 40 is a connecting rod, the cost is very low, and therefore it can be used in vehicles where comfort requirements are not high and cost requirements are relatively high.

[0114] Figure 17 and Figure 18 A schematic diagram of the structure of the fifth embodiment of this application is shown.

[0115] The seat in the fifth embodiment has a largely the same structure as that in the second embodiment, with the main difference being that the second connecting member 50 in the fifth embodiment includes a vibration damping motor. This allows the seat in the fifth embodiment to achieve lateral tilting by controlling the movement of the lead screw motor and to achieve active vibration damping in the height direction by controlling the vibration damping motor.

[0116] Figure 19 and Figure 20 A schematic diagram of the structure of the sixth embodiment of this application is shown.

[0117] The structure of the seat in the sixth embodiment is basically the same as that in the second embodiment, with the main difference being that in the sixth embodiment, the second connecting member 50 includes a connecting rod 54. In this embodiment, since the second connecting member 50 is a connecting rod 54, the seat cannot achieve vibration reduction in the height direction Z. Conversely, by setting the second connecting member 50 as a connecting rod, the cost is very low, and therefore it can be used in vehicles where the requirements for vibration reduction in the height direction Z are not high and the cost requirements are relatively high.

[0118] Figure 21 and Figure 22 A structural schematic diagram of the seventh embodiment of this application is shown.

[0119] The seventh embodiment of the seat has a largely the same structure as the third embodiment, also employing a dual-screw motor. The main difference lies in the fact that, in the seventh embodiment, the seat further includes a third drive assembly. This third drive assembly is configured to drive the seat body 10 to swing about an axis parallel to the first direction Y, meaning the seat body 10 swings back and forth about an axis in the left-right direction. When the vehicle accelerates, the seat body is controlled to rotate so that the front end swings downwards to provide a counterforce to the passenger, mitigating the impact of inertia on the passenger. When the vehicle decelerates, the seat body is controlled to rotate so that the front end swings upwards to provide a counterforce to the passenger, mitigating the discomfort caused by the forward lurch due to inertia.

[0120] refer to Figure 22 The third drive assembly includes a drive member 200 and an intermediate connector 210. A first end of the drive member 200 is rotatably connected to the seat body 10, and a second end of the drive member 200 is rotatably connected to the intermediate connector 210. The intermediate connector 210 is rotatably connected to the seat body 10, and the first end and the second end of the drive member 200 are telescopically connected to drive the seat body 10 to rotate.

[0121] like Figure 22 As shown, the drive unit 200 includes a drive motor, which is a lead screw motor, comprising a lead screw and a nut sleeved on the lead screw. The lead screw rotates under the drive of the motor shaft, and the nut moves linearly along the lead screw. The nut is rotatably connected to the front end of the seat body 10. Specifically, the nut is rotatably connected to the connecting housing 14 on the seat body 10 at a first position A. The motor housing 240 of the lead screw motor is rotatably connected to the intermediate connecting member 210 at a second position B. The intermediate connecting member 210 is rotatably connected to the rear end of the seat body 10 at a third position C. Thus, when the nut of the drive motor moves along the lead screw, it can drive the seat body to swing back and forth.

[0122] In this embodiment, the first connecting portion 311 of the first rocker arm 31 of the first drive assembly is rotatably connected to the bracket 15, and the bracket 15 is fixedly connected to the connecting housing 14, thereby realizing the rotatable connection between the first connecting portion 311 of the first rocker arm 31 and the seat body 10. The connection methods of other structures of the first drive assembly are basically the same as those in the third embodiment, and will not be described again here.

[0123] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and not to limit them; although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this application or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of this application, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in this application.
