[0043] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0044] like Figures 1 to 5 As shown, in one embodiment, the seat drive device 100 includes a connecting seat 1, a support member 2, a connecting assembly 3, a driving assembly 4 and a traction assembly 5; wherein, the connecting seat 1 is used to connect the seat 200; one end of the connecting assembly 3 is rotatably connected to the connecting seat 1, and the other end of the connecting assembly 3 is rotatably connected to the support member 2, so that the connecting seat 1 can be rotated relative to the support member 2; the support member 2 is suitable for sliding connection to the support seat 6; the driving assembly 4 is connected to the support member 2, and the driving assembly 4 can drive the support member 2 to slide relative to the support seat 6; one end of the traction assembly 5 is rotatably connected to the connecting seat 1, and one end of the traction assembly 5 is suitable for connecting to the support seat 6.

[0045] The support member 2 is slidably connected to the support seat 6, which means that the support member 2 is connected to the support seat 6 and can move linearly relative to the support seat 6.

[0046] In this embodiment, when the drive assembly 4 drives the support member 2 to slide relative to the support base 6, the support member 2 can drive the connecting assembly 3 and the connecting base 1 to move linearly relative to the support base 6. When the connecting assembly 3 slides relative to the support base 6, the traction assembly 5 applies force to the connecting base 1, causing the connecting base 1 to rotate relative to the connecting assembly 3, thereby driving the connecting base 1 to tilt and swing. In other words, in this embodiment, the linear motion and rotational motion of the connecting base 1 can occur simultaneously. When the seat drive device 100 is used in a vehicle, the tilt angle of the seat 200 connected to the seat drive device 100 can be adjusted according to actual needs, thereby improving passenger comfort and safety. For example, when the seat drive device 100 is used in a vehicle, the connecting base 1 can tilt in the left-right direction. When the vehicle turns left, the passenger's body may tilt to the right due to centrifugal force. In this case, the tilt angle of the seat 200 can be adjusted in the opposite direction to offset the centrifugal force, thereby improving passenger comfort and safety.

[0047] In addition, the force applied by the traction assembly 5 to the connecting base 1 is also transmitted to the connecting assembly 3, causing the connecting assembly 3 to rotate relative to the support member 2. When the connecting assembly 3 rotates, it can also drive the connecting base 1 and the seat 200 to rotate. This arrangement can improve the riding comfort of the seat 200 and increase the rotation angle and horizontal displacement of the seat 200.

[0048] It should be understood that when the connecting base 1 moves, the seat 200 connected to the support base 1 can be driven to move, and the connecting base 1 and the seat 200 can move synchronously. During assembly, the seat 200 can be locked on the connecting base 1 by bolts or the like.

[0049] The direction in which the connecting base 1 slides linearly relative to the supporting base 6 may intersect with the axis around which the connecting base 1 rotates. Preferably, the direction in which the connecting base 1 moves linearly relative to the supporting base 6 may be perpendicular to the axis around which the connecting base 1 rotates.

[0050] In addition, the direction in which the support member 2 slides relative to the support seat 6 is parallel to the first direction, the connecting seat 1 can tilt and swing in the first direction, the connecting seat 1 and the support member 2 are spaced apart along the second direction, and the first direction and the second direction intersect. Preferably, the first direction is perpendicular to the second direction. When the connecting seat 1 tilts and swings in the first direction, in the second direction, one of the two ends of the connecting seat 1 in the first direction is close to the support member 2, and the other end is away from the support member 2. Figure 5 In the directions shown, the first direction is parallel to the X-axis and the second direction is parallel to the Z-axis.

[0051] It should be understood that the support member 2 can slide back and forth relative to the support base 6 along the first direction, thereby driving the connecting base 1 to reciprocate in the first direction. In the first direction, the connecting base 1 is disposed at the first end and the second end opposite to each other. By definition, the direction from the first end of the connecting base 1 to the second end of the connecting base is the positive direction of the first direction, and the direction from the second end of the connecting base 1 to the first end of the connecting base 1 is the negative direction of the first direction.

[0052] In one embodiment, when the support member 2 slides relative to the support base 6 along the positive direction of the first direction, the first end of the connecting base 1 approaches the support member 2 in the second direction, and the second end of the connecting base 1 moves away from the support member 2 in the second direction. When the support member 2 slides relative to the support base 6 along the negative direction of the first direction, the first end of the connecting base 1 moves away from the support member 2 in the second direction, and the second end of the connecting base 1 moves closer to the support member 2 in the second direction.

[0053] In one application scenario, the first direction is the left-right direction and the second direction is the vertical direction. That is, in this scenario, the driving component 4 can drive the connecting base 1 to reciprocate linearly in the left-right direction and can drive the connecting base 1 to tilt and swing in the left-right direction.

[0054] In addition, in the scenario where the first direction is the left-right direction and the second direction is the vertical direction, the inclination angle of the connecting seat 1 in the left-right direction is greater than or equal to 0°. When the inclination angle of the connecting seat 1 in the horizontal direction is 0°, the connecting seat 1 is in a horizontal state. At this time, the seat 200 connected to the connecting seat 1 is also in a horizontal state (refer to Figure 2When the tilt angle of the connector 1 in the horizontal direction is not 0°, the connector 1 is tilted to the left (refer to Figure 3 ), or, the connector 1 is tilted to the right (refer to Figure 4 ).

[0055] The direction from left to right may be the positive direction of the first direction, and the direction from right to left may be the opposite direction of the first direction. In this case, the first end of the connecting seat 1 is located on the left side of the connecting seat 1, and the second end of the connecting seat 1 is located on the right side of the connecting seat 1. When the connecting seat 1 tilts to the left, the height of the left side of the connecting seat 1 (i.e., the first end of the connecting seat 1) decreases, and the height of the right side of the connecting seat 1 (i.e., the second end of the connecting seat 1) increases; when the connecting seat 1 tilts to the right, the height of the left side of the connecting seat 1 increases, and the height of the right side of the connecting seat 1 decreases. When the connecting seat 1 is in a horizontal state, the height of the left side of the connecting seat 1 is equal to the height of the right side of the connecting seat 1; when the connecting seat 1 is tilted to the left, the height of the left side of the seat 200 is less than the height of the right side of the seat 200; when the connecting seat 1 is tilted to the right, the height of the left side of the seat 200 is greater than the height of the right side of the seat 200.

[0056] In addition, when the driving component 4 drives the connecting seat 1 to move linearly to the left, it can simultaneously drive the connecting seat 1 to tilt to the right; when the driving component 4 drives the connecting seat 1 to move linearly to the right, it can simultaneously drive the connecting seat 1 to tilt to the left.

[0057] In addition, the connecting seat 1 can be located above the support member 2; when the connecting seat 1 tilts to the left, the left side of the connecting seat 1 is close to the support member 2, and the right side of the connecting seat 1 is away from the support member 2; when the connecting seat 1 tilts to the right, the right side of the connecting seat 1 is close to the support member 2, and the left side of the connecting seat 1 is away from the support member 2.

[0058] like Figure 5 As shown, the connecting seat 1 has a support surface 11, which is a plane and is used to install the seat 200. The connecting seat 1 is in a horizontal state, which actually means that the support surface 11 is parallel to the horizontal plane; when the connecting seat 1 tilts to the left, it actually means that the support surface 11 tilts to the left, so that the height of the left end of the support surface 11 is less than the height of the right end; when the connecting seat 1 tilts to the right, it actually means that the support surface 11 tilts to the right, so that the height of the left end of the support surface 11 is greater than the height of the right end.

[0059] like Figure 5 As shown, in one embodiment, the support member 2 has a first sliding structure 21 , which is suitable for cooperating with a second sliding structure 61 on the support seat 6 to guide the sliding of the support member 2 relative to the support seat 6 .

[0060] The first sliding structure 21 may be a slider, and the second sliding structure 61 may be a slide rail.

[0061] like Figure 6 and Figure 7 As shown, the second sliding structure 61 is provided with a sliding groove 62. The first sliding structure is disposed within the sliding groove 62 and is capable of sliding along the extension direction of the sliding groove 62. The groove wall of the sliding groove 62 can limit and guide the first sliding structure 21. Alternatively, the sliding groove 62 can extend through the second sliding structure 61. In one application scenario, the sliding groove 62 extends in the left-right direction.

[0062] like Figure 5 As shown, in one embodiment, the support member 2 further includes a support plate 22, which is connected to the first sliding structure 21. In addition, the support plate 22 is rotatably connected to the connecting assembly 3, thereby realizing the rotational connection between the connecting assembly 3 and the support member 2. The support plate 22 is connected to the driving assembly 4, thereby realizing the connection between the driving assembly 4 and the support member 2.

[0063] The support plate 22 may be a rectangular parallelepiped structure. In addition, the support plate may be connected to the first sliding structure 21 via bolts or the like, or the support plate and the first sliding structure 21 may be welded together.

[0064] like Figure 5 As shown, in one embodiment, the connecting assembly 3 includes a first connecting member 31 and a second connecting member 32. The first end of the first connecting member 31 is rotatably connected to the support member 2, and the second end of the first connecting member 31 is rotatably connected to the connecting base 1. The first end of the second connecting member 32 is rotatably connected to the support member 2, and the second end of the second connecting member 32 is rotatably connected to the connecting base 1. After assembly, the first connecting member 31, the second connecting member 32, the support member 2, and the connecting base 1 form a four-bar linkage.

[0065] The fact that one end of the connecting assembly 3 is rotatably connected to the connecting base 1 means that the second end of the first connecting member 31 is rotatably connected to the connecting base 1, and the second end of the second connecting member 32 is rotatably connected to the connecting base 1. The fact that one end of the connecting assembly 3 is rotatably connected to the connecting base 1 means that the first end of the first connecting member 31 is rotatably connected to the supporting member 2, and the first end of the second connecting member 32 is rotatably connected to the supporting member 2.

[0066] In addition, both the first connecting member 31 and the second connecting member 32 may be connected to the support plate 22 .

[0067] In addition, the first connecting member 31 can rotate relative to the support member 2 around the first axis, the first connecting member 31 can rotate relative to the connecting seat 1 around the second axis, the second connecting member 32 can rotate relative to the support member 2 around the third axis, and the second connecting member 32 can rotate relative to the connecting seat 1 around the fourth axis.

[0068] It should be noted that any one of the first axis, the second axis, the third axis and the fourth axis intersects with the first direction and the second direction.

[0069] In addition, any two of the first axis, the second axis, the third axis and the fourth axis are parallel and spaced apart. Preferably, the first axis, the second axis, the third axis and the fourth axis are all parallel to the third direction, wherein any two of the first direction, the second direction and the third direction intersect. Figure 5 In the shown orientation, the third direction is parallel to the Y-axis.

[0070] Preferably, any two of the first direction, the second direction, and the third direction are perpendicular to each other. When the first direction is the left-right direction and the second direction is the vertical direction, the third direction is the front-back direction.

[0071] like Figure 4 As shown, in one embodiment, the first connecting member 31 and the second connecting member 32 are cross-arranged, which can rationally utilize space and avoid the four-bar linkage from occupying too much space, thereby facilitating the miniaturization design of the entire seat drive device 100 and facilitating the installation and use of the seat drive device 100.

[0072] Specifically, the direction from the first end of the first connector 31 to the first end of the second connector 32 is opposite to the direction from the second end of the first connector 31 to the second end of the second connector 32. In addition, along the third direction, the first connector 31 and the second connector 32 may be spaced apart.

[0073] In one embodiment, the first connecting member 31 and the second connecting member 32 may both be rod-shaped or plate-shaped structures. Specifically, both may be rectangular parallelepiped structures.

[0074] like Figure 6 and Figure 7 As shown, in one embodiment, the driving assembly 4 includes a power source 41 and a transmission mechanism 42. The power source 41 is connected to the support member 2 through the transmission mechanism 42. When working, the power of the power source 41 is transmitted to the support member 2 through the transmission mechanism 42 to drive the support member 2 to move in a straight line.

[0075] like Figure 6 and Figure 7As shown, in one embodiment, the power source 41 includes a motor 411, and the transmission mechanism 42 includes a gearbox 421, a gear set, and a screw 422. The gearbox 421 is connected to the first sliding structure 21, and the gear set is installed in the gearbox 421 and is connected to the screw 422 by a worm gear. That is, the gear set includes a worm gear, the screw 422 is a worm gear, and the worm gear and the worm gear cooperate. The screw 422 is connected to the second sliding structure 61. The motor 411 is connected to the gearbox 421 and can drive the gear set to rotate. When the motor 411 drives the gear set to rotate, it can drive the screw 422 to rotate, so that the gearbox 421 can drive the first sliding structure 21 to move linearly. When the first sliding structure 21 moves linearly, it can drive the support member 2 to move linearly.

[0076] In one embodiment, the screw rod 422 may be disposed in the slide groove 62. In addition, the screw rod 422 may be connected to the second sliding structure 61 through a corresponding support structure so that the screw rod 422 is spaced apart from the bottom surface of the slide groove 62. Moreover, the screw rod 422 can rotate relative to the support structure around its own axis, wherein the axis of the screw rod 422 is parallel to the left and right directions. For example, the screw rod 422 may be supported by a support block, wherein the support block may be fixed on the bottom surface of the slide groove 62, the support block is provided with a support hole, the screw rod 422 is passed through the support hole, and can rotate relative to the support block around its own axis; in addition, two support blocks are provided, one for supporting the two ends of the screw rod 422; and the screw rod 422 may be connected to the support block through a bearing, specifically, the support hole is interference fit with the outer ring of the bearing, and the screw rod 422 is interference fit with the inner ring of the bearing.

[0077] In one embodiment, the drive assembly 4 also includes a mounting plate 43 and a connecting shaft 44. The mounting plate 43 is connected to the gear box 421. The housing of the motor 411 is installed on the mounting plate 43. The output shaft of the motor 411 is connected to the gear set through the connecting shaft 44. In addition, the connecting shaft 44 can be a soft shaft.

[0078] The motor 411 can be clamped on the mounting plate 43, or the motor 411 can be connected to the mounting plate 43 by bolts or the like. In addition, the mounting plate 43 and the gear box 421 can be connected together by bolts or the like.

[0079] like Figures 9 to 11As shown, in one embodiment, the pulling assembly 5 includes a first pulling member 51, a second pulling member 52, and a third pulling member 53. The first end of the first pulling member 51 is adapted to be rotatably connected to the support base 6, and the second end of the first pulling member 51 is rotatably connected to the connecting base 1. The first end of the second pulling member 52 is adapted to be rotatably connected to the support base 6, and the second end of the second pulling member 52 is rotatably connected to the first end of the third pulling member 53. The second end of the third pulling member 53 is rotatably connected to the connecting base 1. After assembly, the first pulling member 51, the second pulling member 52, the third pulling member 53, the support member 2, and the connecting base 1 form a five-bar linkage.

[0080] The connection of one end of the traction assembly 5 to the support base 6 means that the first end of the first traction member 51 is rotationally connected to the support base 6, and the first end of the second traction member 52 is rotationally connected to the support base 6. The rotational connection of one end of the traction assembly 5 to the connection base 1 means that the second end of the first traction member 51 is rotationally connected to the connection base 1, and the second end of the third traction member 53 is rotationally connected to the connection base 1.

[0081] Along the first direction, an area where the connecting seat 1 connects to the first traction member 51 (defined as the first area) and an area where the connecting seat 1 connects to the third traction member 53 (defined as the second area) are arranged at intervals.

[0082] When the support member 2 is driven to move linearly, the support member 2 drives the connecting seat 1 to move linearly through the first connecting member 31 and the second connecting member 32. At this time, the connecting seat 1 can apply force to the first traction member 51 and the third traction member 53 to rotate the first traction member 51 and the third traction member 53. At the same time, the connecting seat 1 will also be subjected to the reaction force of the first traction member 51 and the third traction member 53, thereby causing the connecting seat 1 to tilt.

[0083] Among them, when the driving component 4 drives the connecting seat 1 to move linearly along the direction from the first area to the second area, it can simultaneously drive the connecting seat 1 to tilt toward the first area. At this time, the height of the second area increases and the height of the first area decreases, that is, the second area is away from the support member 2, and the first area is close to the support member 2; when the driving component 4 drives the connecting seat 1 to move linearly along the direction from the second area to the first area, it can simultaneously drive the connecting seat 1 to tilt toward the second area. At this time, the height of the first area increases and the height of the second area decreases, that is, the first area is away from the support member 2, and the second area is close to the support member 2.

[0084] In this embodiment, by setting the traction mechanism 4, it is possible to achieve a power source driving the connecting seat 1 to move linearly along the first direction and simultaneously drive the connecting seat 1 to tilt in the first direction, which can reduce the number of power sources and thus reduce costs.

[0085] Among them, the first traction member 51 can rotate relative to the support seat 6 around the fifth axis, and the first traction member 51 can rotate relative to the connecting seat 1 around the sixth axis; the second traction member 52 can rotate relative to the support seat 6 around the seventh axis, and the second traction member 52 can rotate relative to the third traction member 53 around the eighth axis; the third traction member 53 can rotate relative to the connecting seat 1 around the ninth axis, and any two of the fifth axis, sixth axis, seventh axis, eighth axis and ninth axis can be parallel and spaced apart, and all five can be parallel to the third direction.

[0086] In addition, the first axis, the second axis, the third axis, the fourth axis, the fifth axis, the sixth axis, the seventh axis, the eighth axis and the ninth axis may be parallel to each other and spaced apart.

In addition, the concave structure 45 is provided on the upper surface of the mounting plate 43.

[0106] like Figure 8 As shown, in the third direction, the connecting arm 7 includes a first section plate 71, a second section plate 72, a third section plate 73, a fourth section plate 74 and a fifth section plate 75 connected in sequence, wherein an L-shaped structure is formed between the first section plate 71 and the second section plate 72, an L-shaped structure is formed between the second section plate 72 and the third section plate 73, an L-shaped structure is formed between the third section plate 73 and the fourth section plate 74, and an L-shaped structure is formed between the third section plate 73 and the fifth section plate 75.

[0107] In addition, the first section plate 71, the second section plate 72, the third section plate 73, the fourth section plate 74 and the fifth section plate 75 are all flat plate structures.

[0108] like Figure 5As shown, in one embodiment, in the third direction, the connecting base 1 includes a first plate 12, a second plate 13, and a third plate 14 connected in sequence. In the second direction, the first plate 12 is located on the side of the second plate 13 closer to the support member 2, and the third plate 43 is located on the side of the second plate 13 farther from the second support member.

The support surface 11 is located on the second plate 13, and the second plate 13 is used to connect to the seat. The third plate 14 is connected to the connecting arm 7. This arrangement facilitates the connection of the connecting base 1 to the connecting assembly 3 and the traction assembly 5, and facilitates the connection of the connecting base 1 to the seat 200 and the connecting arm 7.

[0111] In addition, the second plate 13 is horizontally arranged, wherein the second plate 13 is horizontally arranged means that when the seat 200 is in the initial state, the second plate 13 is horizontally arranged, at this time, the support surface 11 is parallel to the horizontal plane. In addition, the support surface 11 is the upper surface of the second plate 13.

[0115] exist Figures 9 to 11 In the direction shown, the first traction member 51 is located on the left side of the third traction member 53. Figures 9 to 11 , the working principle of this scheme is:

[0116] The seat inclination is R (°), the seat inclination change rate is ΔR (° / ms), the length of the first connecting member 31 is L1 (mm), the length of the second connecting member 32 is L2 (mm), and the distance between the second axis and the fourth axis is L3 (mm). The angle between the second connecting member 32 and the support member 2 is a (°), and the angle between the first connecting member 31 and the support member 2 is b (°). H1 = sinb*L2, H2 = sinb*L1. The angles between the second connecting member 32 and the support member 2, as well as the angle between the first connecting member 31 and the support member 2, can be detected by an angle sensor. The formula for calculating the seat angle change rate ΔR is as follows:

[0117]

[0118] Among them, the hinge point of the first connecting member 31 and the support member 2 is defined as the first hinge point, the hinge point of the first connecting member 31 and the connecting seat 1 is defined as the second hinge point, the hinge point of the second connecting member 32 and the support member 2 is defined as the third hinge point, and the hinge point of the support member 2 and the connecting seat 1 is defined as the fourth hinge point; the line connecting the first hinge point and the second hinge point is defined as the first line, the line connecting the third hinge point and the fourth hinge point is defined as the second line, the line connecting the first hinge point and the third hinge point is defined as the third line, and the line connecting the second hinge point and the fourth hinge point is defined as the fourth line; the third line is parallel to the fourth line; the angle between the first connecting member 31 and the support member 2 may refer to: the angle between the first line and the third line; the angle between the second connecting member 32 and the support member 2 may refer to: the angle between the second line and the third line.

[0119] In addition, L1 is the distance between the first hinge point and the second hinge point, L2 is the distance between the third hinge point and the fourth hinge point, and L3 is the distance between the second hinge point and the fourth hinge point.

[0120] refer to Figure 9 and Figure 10 When the support member 2 moves to the right: the connecting seat 1 moves to the right and the connecting seat 1 tilts to the left; specifically: the support member 2 drives the first connecting member 31 and the second connecting member 32 to move to the right, at this time the angle formed by the first connecting member 31 and the support member 2 changes from a to a1, a1>a, the angle formed by the second connecting member 32 and the support member 2 changes from b to b1, b1<b, the first traction member 51, the second traction member 52 and the third traction member 53 move with the change of the angles a and b, c changes to c1, c1>c, d changes to d1, d1<d; thereby causing the connecting seat 1 to move and tilt in the left and right directions, and then the seat 200 to move and tilt in the left and right directions.

[0121] refer to Figure 9 and Figure 11When the support member 2 moves to the left, the principle is the same as that of the support member 2 moving to the right. At this time, a becomes a2, b becomes b2, c becomes c2, and d becomes d2, where a2<a, b2>b, b2<b, d2>d.

[0122] An embodiment of the present invention further provides a vehicle, which includes a seat 200 and the seat drive device 100 described in any one of the above embodiments. The seat drive device 100 is connected to the seat 200 and is used to adjust the tilt angle of the seat 200 in the left and right directions.

[0123] Furthermore, the seat drive device 100 is mounted on the vehicle floor. In one embodiment, one seat drive device 100 typically supports and mounts one seat 200. A vehicle typically has multiple seats 200, where "multiple" means greater than or equal to two, and "multiple" has the same meaning in all embodiments.

[0124] In one scenario, the number of seats 200 may be equal to the number of seat drive devices 100. In this case, each seat 200 is mounted on a corresponding seat drive device 100. In another scenario, the number of seats 200 may be greater than the number of seat drive devices 100. In this case, some seats 200 are mounted on the seat drive devices 100, while other seats 200 are not. When a seat 200 is mounted on the seat drive device 100, it can be driven by the seat drive device 100 to tilt the seat 200 in the left-right direction.

[0125] It should be understood that the above-mentioned related designs can also be replaced by other methods, such as:

[0126] In other embodiments, in order to achieve the rotational connection between the connecting seat 1 and the support member 2, the connecting component 3 may also adopt other settings. For example, the connecting component 3 may also have only one of the first connecting member 31 and the second connecting member 32.

[0127] When the connecting seat 1 and the support member 2 are rotatably connected together through the rotating shaft, the implementation method can be: the connecting seat 1 and the support member 2 can be provided with corresponding connecting holes, the rotating shaft is passed through the connecting holes of the two, and the connecting seat 1 and the support member 2 can both rotate around the axis of the rotating shaft, and the axis of the rotating shaft is parallel to the front and rear directions; or, the connecting seat 1 is fixedly connected to the rotating shaft, and a connecting hole is provided on the support member 2, wherein the rotating shaft is passed through the connecting hole, so that the connecting seat 1 can rotate around the axis of the rotating shaft relative to the support member 2; or, the support member 2 is fixedly connected to the rotating shaft, and a connecting hole is provided on the connecting seat 1, wherein the rotating shaft is passed through the connecting hole, so that the connecting seat 1 can rotate around the axis of the rotating shaft relative to the support member 2.

[0128] In other embodiments, the support member 2 and the first sliding structure 21 may also be an integrally formed structure.

[0129] In other embodiments, the screw rod 422 can be replaced with a rack. In this case, the gear of the gear train meshes with the rack, which is then fixedly connected to the support base 6 (or the second sliding structure 61). When the motor 411 drives the gear train to rotate, the motor 411, gear box 421, and other components can move linearly along the rack. Furthermore, the connecting shaft 44 can be omitted; in this case, the shaft of the motor 411 is directly connected to the gear train.

[0130] In other embodiments, the drive assembly 4 may also include a motor 411 and a screw transmission mechanism, wherein the motor 411 is connected to the screw of the screw transmission mechanism, the nut of the screw transmission mechanism is connected to the first sliding structure 21, and the screw extends along the left and right directions. When the motor 411 drives the screw to rotate, the first sliding structure 21 can be driven to move linearly through the nut of the screw transmission mechanism.

[0131] In other embodiments, other methods may be used to drive the connecting base 1 to rotate. For example, the traction assembly 5 may be an electric cylinder. During operation, when the drive assembly 4 drives the support member 2 to move linearly, the traction assembly 5 applies a force to the connecting base 1 in the direction from the connecting base 1 to the base 6 or in the direction from the base 6 to the connecting base 1, thereby achieving rotation of the connecting base 1. The specific connection method may be: the first end of the electric cylinder is rotationally connected to the connecting base 1, the second end of the electric cylinder is rotationally connected to the base 6, and the axis about which the electric cylinder rotates relative to the connecting base 1 may be parallel to the axis about which the electric cylinder rotates relative to the base 6. In addition, when the electric cylinder is operating, the distance between the first end of the electric cylinder and the second end of the electric cylinder can be increased or decreased. In addition, in the first direction, the area where the connecting base 1 connects to the first connector 31 and the area where the connecting base 1 connects to the second connector 32 are located on the same side of the area where the connecting base 1 connects to the electric cylinder. In this case, the first connector 31 and the second connector 32 may be located on the same side of the electric cylinder.

[0132] The present invention also provides a seat control method for controlling a seat 200 to operate in at least one of a welcome mode, a first posture holding mode, a second posture holding mode, a first cradle mode, and a second cradle mode. The control method is used to control the vehicle described above, and each mode can be implemented using the seat drive device 100 described in any of the above embodiments.

[0133] In one embodiment, the welcoming mode includes: step S1, detecting whether there is a target person outside the vehicle who wants to get on the vehicle; if so (that is, a target person is detected outside the vehicle), executing step S2, wherein step S2 is: detecting the boarding position of the target person; step S3, adjusting the outward tilt angle of the first seat corresponding to the boarding position; step S4, detecting whether the target person is sitting on the first seat; if so (that is, it is detected that the target person has sat on the first seat), executing step S5, wherein step S5 is: controlling the first seat to reset.

[0134] It should be understood that the vehicle has multiple seats 200. In this embodiment, the seat 200 corresponding to the boarding position is defined as the first seat. Furthermore, the first seat can be mounted on the seat drive device 100 described in any of the aforementioned embodiments. In step S1, if no target person is detected boarding the vehicle, the subsequent steps are discontinued and the process continues with step S1. In step S4, if no target person is detected seated in the first seat, the subsequent steps are discontinued, the first seat remains in the reclined position, and the process continues with step S4.

[0135] In addition, when the vehicle is parked or moving, the seat 200 is horizontal in the left and right directions, that is, the seat 200 is not tilted in the left and right directions, and the height of the left side of the seat 200 is equal to the height of the right side of the seat 200. In the welcoming mode, the seat 200 tilts outward to facilitate passengers getting on the vehicle. When the passengers are seated firmly, the seat 200 will reset, that is, reset to be horizontal in the left and right directions.

[0136] The step of detecting whether a target person outside the vehicle intends to board the vehicle includes: step S11, detecting whether there is a person within a predetermined range around the vehicle, wherein the person within the predetermined range is the target person; if so (i.e., a person is detected within the predetermined range around the vehicle), executing step S12, wherein step S12 is detecting whether the target person reaches out to open the door; if so (i.e., the target person reaches out to open the door), determining that the target person intends to board the vehicle. This allows for more precise seat control, further improving passenger comfort.

[0137] Wherein, in step S11, if no one is detected in the predetermined range around the vehicle, then no one wants to get on the bus at this time, so no subsequent steps are performed. In step S12, if no target person is detected to stretch out his hand to open the door, then the target person does not need to get on the bus at this time, so no subsequent steps are performed.

[0138] Specifically, the radar on the vehicle can sense whether there are people within a predetermined range around the vehicle. The radar's sensing range is the predetermined range. The radar's sensing distance can be 5 meters, and the predetermined range is 5 meters or less from the vehicle. When the distance between a person and the vehicle is less than or equal to 5 meters, they can be sensed by the radar. At this time, it can be determined that there are people within the predetermined range around the vehicle. It should be noted that the radar can detect in all directions around the vehicle. Of course, the sensing range of the radar on the vehicle can also be other values. During production, a radar with a corresponding sensing range can be selected according to actual needs.

[0139] When the radar detects a target person, the camera on the vehicle can track and capture the target person, and use this to determine whether the target person reaches out to open the door. The camera is defined as a first camera, which can be installed outside the vehicle.

[0140] Furthermore, the operations of detecting whether a person is approaching the vehicle using radar and determining whether a target person is reaching out to open the door based on images captured by the camera are both existing technologies. In other embodiments, the first camera may be used to capture images of the vehicle's surroundings so that the onboard controller can determine whether a person is within a predetermined range around the vehicle.

[0141] In addition, the target person's boarding position refers to which door the target person boards the vehicle. Specifically, when the camera captures the target person reaching out to open a door, the door is the target person's boarding position, and the seat 200 corresponding to the door refers to the seat 200 closest to the door, and the seat 200 is the first seat.

[0142] For example, a vehicle has four doors, namely a left front door, a right front door, a left rear door, and a right rear door. The seats 200 in the vehicle include a driver's seat, a passenger seat, a left rear seat, a right rear seat, and a middle rear seat. In this case, the left front door corresponds to the driver's seat, the right front door corresponds to the passenger seat, the left rear door corresponds to the left rear seat, and the right rear door corresponds to the right rear seat. When the target person reaches out to open the left front door, the left front door becomes the target person's boarding position, and the first seat becomes the driver's seat.

[0143] Outward tilting of the first seat means that, in the left-right direction, the side of the first seat closest to the corresponding door is lowered, while the side of the first seat further from the corresponding door is raised. Specifically, when the first seat is seat 200 near the left door (e.g., the driver's seat or the left rear seat), outward tilting of the first seat means that the left side of the first seat moves downward and the right side of the first seat moves upward, and in this case, the connecting seat 1 connected to the first seat tilts to the left. When the first seat is seat 200 near the right door (e.g., the passenger seat or the right rear seat), outward tilting of the first seat means that the right side of the first seat moves downward and the left side of the first seat moves upward, and in this case, the connecting seat 1 connected to the first seat tilts to the right.

[0144] In one embodiment, between step S2 and step S3, it is further included to detect whether there is a person or object on the first seat. If not, step S3 can be executed; if yes, step S3 is not executed.

[0145] The operation of determining whether the first seat is occupied may be performed by using an image of the vehicle interior captured by a camera. The camera may be a second camera installed in the vehicle. Alternatively, the operation of detecting whether the first seat is occupied by a person or object may be performed by using a pressure sensor installed on the first seat.

[0146] In one embodiment, after detecting that there is a target person within a predetermined range around the vehicle, it also includes: detecting the body information of the target person, the body information including weight information and height information; according to the body information, retrieving the pre-stored seat 200 adaptation position information corresponding to the body information; at this time, the above-mentioned step S3 is specifically: adjusting the outward tilt angle of the first seat corresponding to the boarding position according to the seat 200 adaptation position information.

[0147] Specifically, when the radar on the vehicle detects the target person, it will continue to detect the distance between the target person and the vehicle. When the distance between the target person and the vehicle is less than a preset value, the corresponding camera (the camera can be the first camera) will take a picture of the target person, and the subsequent on-board controller will obtain the target person's height and weight information based on the image taken by the camera.

[0148] The adaptive position information of the seat 200 may include the outward tilt angle of the seat 200. The vehicle controller may pre-store the adaptive position information of the seat 200 corresponding to different body posture information. After the body posture information of the target person is subsequently detected, the adaptive position information corresponding to the body posture information can be directly retrieved. The correspondence between body posture information and the adaptive position information of the seat 200 may be similar to the correspondence between height and weight information and clothing size information.

[0149] In one embodiment, the step of detecting whether the target person is seated in the first seat includes detecting whether the opening angle of the door corresponding to the boarding position is decreasing. If so (i.e., the opening angle of the door corresponding to the boarding position is detected to be decreasing), it is determined that the target person has sat in the first seat. This facilitates providing a start signal for the seat resetting action.

[0150] The decreasing opening angle of the door corresponding to the boarding position (i.e., the door corresponding to the first seat) indicates that the door is closing, which in turn indicates that the target person has taken a seat in the first seat. Furthermore, the door opening angle can be detected by a corresponding angle sensor installed on the vehicle (referred to as a door angle sensor). The type and mounting method of the door angle sensor can be conventional.

[0151] In one embodiment, if the door opening angle corresponding to the boarding position is not detected decreasing, the system detects whether the pressure on the first seat has reached a first value. If so, the system detects whether the duration of the pressure on the first seat reaching the first value has reached a second value. If so, the system determines that the target person has occupied the first seat. This allows the first seat to be automatically reset even if door angle detection fails or the target person fails to close the door, ensuring a more comfortable and safe ride for the target person.

[0152] The pressure on the first seat may be detected by a pressure sensor mounted on the first seat, which is defined as a first pressure sensor. The first pressure sensor may be mounted in a central area of ​​the first seat. The pressure on the first seat reaching a first value may mean that the pressure on the first seat is greater than or equal to the first value.

[0153] In one embodiment, "detecting whether the pressure applied to the first seat reaches a first value" may refer to the relationship between the pressure applied to the first seat and the weight of the target person. For example, the first value may be 40% of the target person's weight. That is, when the pressure applied to the first seat is greater than or equal to 40% of the pressure generated by the target person's weight (i.e., gravity), the pressure applied to the first seat reaches the first value. Alternatively, the first value may be set to other values, such as 30%, 50%, or the like, and this value may be user-defined.

[0154] In other embodiments, the first value may be a fixed value, such as 300N, etc., wherein the value may be set by the user.

[0155] "The duration of the scenario in which the pressure on the first seat reaches the first value reaches a second value" may mean that the duration of the scenario in which the pressure on the first seat reaches the first value is greater than or equal to the second value, and the second value may be 1 second, 2 seconds, 3 seconds, etc.

[0156] In other embodiments, it is also possible to detect whether the target person is sitting in the first seat by other means, for example, by photographing the target person with a camera to determine the target person's position in the vehicle. The camera may be a second camera installed in the vehicle.

[0157] In one embodiment, after adjusting the outward tilt angle of the first seat corresponding to the boarding position (i.e., step S3), the process also includes detecting whether the pressure and weight information on the side wings of the first seat meet a first predetermined requirement. If not (i.e., the pressure and weight information on the side wings of the first seat do not meet the first predetermined requirement), the first seat is controlled to continue tilting outward until the pressure and weight information on the side wings of the first seat meet the first predetermined requirement. This can compensate for the difficulty of the target person boarding the vehicle due to factors such as errors in the judgment of body posture information, further improving riding comfort.

[0158] "The pressure on the side wing of the first seat and the weight information satisfy the first predetermined requirement" may mean that the ratio of the pressure on the side wing of the first seat to the weight of the target person is greater than or equal to a set value. The set value may be 0.5. In this case, "the pressure on the side wing of the first seat and the weight information satisfy the first predetermined requirement" means that the pressure on the side wing of the first seat is greater than or equal to 50% of the weight of the target person. Of course, the set value may also be other values, such as 0.4, 0.6, etc.

[0159] "The pressure and weight information of the first seat wing does not meet the first predetermined requirement" means that it is difficult for the target person to get on the vehicle. At this time, the first seat can continue to be controlled to tilt outward.

[0160] The pressure on the side wings of the first seat can be detected by pressure sensors installed on the side wings of the first seat. The first seat has two side wings, spaced apart in the left-right direction, and each of the wings can be equipped with a pressure sensor. When the first seat is near the left door (e.g., the driver's seat), the pressure on the side wings referred to herein refers to the pressure on the left side wing of the first seat. When the first seat is near the right door (e.g., the passenger seat), the pressure on the side wings referred to herein refers to the pressure on the right side wing of the first seat.

[0161] In one embodiment, after detecting that a target person outside the vehicle wants to get on the vehicle, it also includes: judging whether the target person's getting-on-the-vehicle posture is to get on the vehicle with one foot; if so (that is, it is determined that the target person's getting-on-the-vehicle posture is to get on the vehicle with one foot), executing the step of adjusting the inclination angle of the first seat corresponding to the said getting-on-the-vehicle position.

[0162] Among them, single-foot boarding means that the target person boards the car sideways. When getting on the car, one foot is stepped into the car first, and after sitting on the seat 200, the other foot is put into the car.

[0163] When the target person is boarding the vehicle with one foot: the target person is facing the front of the vehicle, and the angle between the target person's shoulder width and the length of the vehicle is less than or equal to 45 degrees. The target person's boarding posture can be determined based on an image captured by a camera, which can be a camera installed inside the vehicle. Furthermore, the method for determining whether the target person is boarding the vehicle with one foot can be based on existing techniques.

[0164] If it is determined that the target person does not get on the bus with one foot, step S3 is not executed.

[0165] In one embodiment, the first posture maintaining mode includes: determining whether there is a curve within a preset range in front of the vehicle; if so, determining whether the vehicle speed is greater than or equal to a predetermined value; if so, adjusting the tilt direction of the seat 200 and the tilt angle change speed of the seat 200 according to the steering wheel rotation direction and the steering wheel angle change speed.

[0166] The preset range distance can be 2000 meters. Of course, the preset range can also be other values, such as 150 meters, and can be set by the user. The size of the "preset range" is pre-set when the vehicle leaves the factory, and the user can subsequently set the "preset range" on the vehicle touch screen according to their needs. In addition, the detection of the curve can be achieved by a corresponding detection device installed on the vehicle, such as a camera, and the curve detection method can be existing technology.

[0167] The "predetermined value" can be 40 km / h, or other values, such as 30 km / h, and can be set by the user. The "predetermined value" is pre-set when the vehicle leaves the factory, and the user can subsequently set the "predetermined value" on the vehicle's touchscreen according to their needs. The vehicle speed can be detected by a corresponding speed sensor on the vehicle.

[0168] When the steering wheel turns to the left, the adjustment seat 200 tilts to the right; when the steering wheel tilts to the right, the adjustment seat 200 tilts to the left. The steering wheel's rotation direction and rotation angle can both be detected by corresponding detection devices, and the methods for detecting the steering wheel's rotation direction and rotation angle can both be existing technologies. In addition, the vehicle's control device can receive the detection signal from the detection device to obtain the speed of change of the steering wheel's rotation angle, or the detection device itself can detect the speed of change of the steering wheel's rotation angle. The method for detecting the speed of change of the steering wheel's rotation angle can also be existing technologies.

[0169] The greater the steering wheel angle change rate r, the greater the tilt angle change rate ΔR of the seat 200. For example, r can be 27 times ΔR. Of course, r can also be other multiples of ΔR, or the two can also have other relationships.

[0170] In one embodiment, in the first posture maintaining mode, after determining that the vehicle speed is greater than the predetermined value, the following steps are further included: detecting which of the seats 200 in the vehicle have occupants, wherein the seat 200 having occupants is the second seat; and adjusting the tilt direction and the tilt angle change rate of the seat 200 based on the steering wheel rotation direction and the steering wheel angle change rate: adjusting the tilt direction and the tilt angle change rate of the second seat based on the steering wheel rotation direction and the steering wheel angle change rate. That is, the first posture maintaining mode only adjusts the seat 200 that has occupants.

[0171] The method for detecting which seats 200 have occupants can be to use a second camera inside the vehicle to take photos or to detect using a pressure sensor in the center area of ​​seat 200. In this case, when the pressure detected by the pressure sensor is greater than a certain value, it is determined that an occupant is sitting in the seat 200. This value can be 300N, for example. Furthermore, the method for detecting which seats 200 have occupants can be conventional.

[0172] In one embodiment, the second posture maintaining mode includes: determining whether the vehicle is located on a non-horizontal road; if so, adjusting the tilt direction and tilt angle of the seat 200 according to the tilt direction and tilt angle of the vehicle.

[0173] A non-level road surface refers to a road surface that is tilted in the left-right direction of the vehicle, with the left side lower than the right side, or the left side higher than the right side. When a vehicle is on a non-level road surface, the vehicle will tilt in the left-right direction.

[0174] Determining whether the vehicle is on a non-level road surface on the left or right can be an existing technology. For example, a camera on the vehicle is used to determine whether the vehicle has entered a non-level road section on the left or right. If so, it means that the vehicle is on a non-level road surface on the left or right; or, a level sensor on the vehicle can be used to detect whether the vehicle is on a non-level road surface.

[0175] Alternatively, the vehicle's tilt direction and tilt angle can be determined by a level sensor on the vehicle. When the vehicle tilts to the left, seat 200 is adjusted to the right, with the vehicle's left tilt angle equal to the right tilt angle of seat 200. When the vehicle tilts to the right, seat 200 is adjusted to the left, with the vehicle's right tilt angle equal to the left tilt angle of seat 200. In other words, the vehicle's tilt direction is opposite to the seat 200's, and the vehicle's tilt angle equals the seat 200's tilt angle, thus maintaining seat 200 level.

[0176] In one embodiment, after determining that the vehicle is located on a non-horizontal road section, the method further includes: detecting which of the seats 200 in the vehicle have occupants, wherein the seat 200 with the occupant is the second seat; and adjusting the tilt direction and tilt angle of the seat 200 according to the vehicle's tilt direction and tilt angle comprises adjusting the tilt direction and tilt angle of the second seat according to the vehicle's tilt direction and tilt angle. That is, the second posture holding mode only adjusts the seat 200 with the occupant.

[0177] The method for detecting which seats 200 have occupants in the second posture holding mode is the same as the above method.

[0178] In one embodiment, the first cradle mode includes: receiving a first cradle mode activation instruction; and controlling the seat 200 to swing left and right according to a preset first seat tilt angle and a preset first seat tilt change speed.

[0179] Among them, the activation instruction of the first cradle mode can be that the operator selects and confirms on the vehicle-mounted touch screen. At this time, the corresponding buttons can be displayed on the touch screen. The operator can click these buttons to issue the activation instruction of the first cradle mode, and the vehicle-mounted controller can receive the instruction and control the seat 200 to swing left and right; or, it can also be the operator's voice control, etc. At this time, the voice instruction input by the operator can be received through the microphone on the vehicle.

[0180] In addition, each time the first cradle mode is activated, the operator can manually input the seat 200 tilt angle and the seat 200 tilt change speed on the touch screen. Alternatively, the vehicle controller may pre-store the first seat tilt angle and the first seat tilt change speed corresponding to the first cradle mode.

[0181] Controlling the seat 200 to swing left and right according to the preset first seat tilt angle and the preset first seat tilt change speed means: controlling the seat 200 to tilt to the left to the maximum position according to the preset first seat tilt angle change speed (at this time, the tilt angle of the seat 200 is equal to the preset first seat tilt angle); then, controlling the seat 200 to tilt to the right to the maximum position according to the preset first seat tilt angle change speed (at this time, the tilt angle of the seat 200 is equal to the preset first seat tilt angle); and repeating the above operation; or, it is also possible to control the seat 200 to tilt to the right to the maximum position according to the preset first seat tilt angle change speed (at this time, the tilt angle of the seat 200 is equal to the preset first seat tilt angle); then, controlling the seat 200 to tilt to the left to the maximum position according to the preset first seat tilt angle change speed (at this time, the tilt angle of the seat 200 is equal to the preset first seat tilt angle); and repeating the above operation.

[0182] In one embodiment, the second cradle mode includes: detecting whether the occupant on the seat 200 is a child or an elderly person; if so, detecting the occupant's heart rate; if the occupant's heart rate is greater than or equal to a predetermined value, controlling the seat 200 to swing left and right according to a preset second seat tilt angle and a preset second seat tilt change speed.

[0183] The method for detecting whether the occupant of seat 200 is a child or an elderly person may be to detect the image captured by a camera in the vehicle. Specifically, the corresponding control device in the vehicle may determine whether the occupant of seat 200 is a child or an elderly person based on the image information of the occupant in seat 200 captured by a camera (such as a second camera). The specific determination method may be based on existing technologies. Of course, other existing technologies may also be used to detect whether the occupant of seat 200 is a child or an elderly person.

[0184] The heart rate of the occupants may be detected by using a millimeter-wave radar in the vehicle, wherein the installation method and detection method of the millimeter-wave radar may be existing technologies.

[0185] The tilt angles and tilt angle change speeds of the seat 200 corresponding to different heart rates are stored in the vehicle controller and can be directly called when needed.

[0186] In addition, the number of predetermined values ​​may be multiple, for example, the predetermined values ​​include 65 times / minute and 75 times / minute;

[0187] When the heart rate of the occupant is greater than or equal to 65 beats / minute, the seat 200 is controlled to swing left and right in a mode.

[0188] When the heart rate of the occupant is greater than or equal to 75 beats / minute, the seat 200 is controlled to swing left and right in another mode.

[0189] Controlling the seat 200 to swing left and right according to the preset second seat tilt angle and the preset second seat tilt change speed means: controlling the seat 200 to tilt to the left to the maximum position according to the preset second seat tilt angle change speed (at this time, the tilt angle of the seat 200 is equal to the preset second seat tilt angle); then, controlling the seat 200 to tilt to the right to the maximum position according to the preset second seat tilt angle change speed (at this time, the tilt angle of the seat 200 is equal to the preset second seat tilt angle); and repeating the above operation; or, it is also possible to control the seat 200 to tilt to the right to the maximum position according to the preset second seat tilt angle change speed (at this time, the tilt angle of the seat 200 is equal to the preset second seat tilt angle); then, controlling the seat 200 to tilt to the left to the maximum position according to the preset second seat tilt angle change speed (at this time, the tilt angle of the seat 200 is equal to the preset second seat tilt angle); and repeating the above operation.

[0190] In different cradle modes, the tilt angles of the seat 200 may be the same or different; in different cradle modes, the speeds of change of the left and right tilt angles may be the same or different.

[0191] The present invention also provides a seat control device, which is applied to the above-mentioned vehicle to control the seat of the above-mentioned vehicle, wherein a corresponding computer program is stored in the seat control device, and when the seat control device executes the computer program, the above-mentioned seat control method can be implemented. Specifically, the seat control device includes at least one of a welcome module, a first posture maintaining module, a second posture maintaining module, a first cradle module, and a second cradle module. The seat control device can be an on-board controller as described below, and the welcome module, the first posture maintaining module, the second posture maintaining module, the first cradle module, and the second cradle module can all be corresponding computer programs stored in the seat control device.

[0192] In addition, the welcome module is used to control the vehicle to work in the above-mentioned welcome mode, the first posture maintaining module is used to control the vehicle to work in the above-mentioned first posture maintaining mode, the second posture maintaining module is used to control the vehicle to work in the above-mentioned second posture maintaining mode, the first cradle module is used to control the vehicle to work in the above-mentioned first cradle mode, and the second cradle module is used to control the vehicle to work in the above-mentioned second cradle mode.

[0193] In one embodiment, the welcoming module includes a first detection unit, a second detection unit, a third detection unit, a first adjustment unit and a second adjustment unit; the first detection unit is used to detect whether there is a target person outside the vehicle who wants to get on the vehicle; the second detection unit is used to detect the target person's boarding position when the first detection unit detects that there is a target person outside the vehicle who wants to get on the vehicle; the first adjustment unit is used to adjust the outward tilt angle of the first seat corresponding to the boarding position when the second detection unit detects the target person's boarding position; the third detection unit is used to detect whether the target person is sitting on the first seat; the second adjustment unit is used to control the first seat to reset when the third detection unit detects that the target person is sitting on the first seat.

[0194] The first detection unit, the second detection unit, the third detection unit, the first adjustment unit, and the second adjustment unit may all be corresponding computer programs stored in the seat control device.

[0195] The first detection unit is used to detect whether there is a target person outside the vehicle who wants to get on the vehicle, which may mean: the first detection unit determines whether there is a target person who wants to get on the vehicle through the detection information of the corresponding detection device on the vehicle, for example: the first detection unit controls the operation of the radar on the vehicle, and determines whether there is a target person who wants to get on the vehicle based on the detection results of the radar; or, the first detection unit controls the operation of the first camera on the vehicle to capture images around the vehicle, and determines whether there is a target person who wants to get on the vehicle based on the images captured by the first camera.

[0196] The second detection unit detects the target person's boarding position, which may mean that the second detection unit determines the target person's boarding position through the detection signal of the corresponding detection device on the vehicle. For example, the second detection unit can control the corresponding camera on the vehicle (such as the first camera) to work to track and shoot the target person, and can determine whether the target person reaches out to open the door based on the image captured by the first camera, and then determine the target person's boarding position.

[0197] The third detection unit detects whether the target person is seated in the first seat. This may involve the third detection unit controlling the detection signals of corresponding detection devices on the vehicle to determine whether the target person is seated in the first seat. For example, the third detection unit may control a corresponding camera (e.g., a second camera) to capture the target person's position within the vehicle and determine whether the target person is seated in the first seat based on the image captured by the second camera. Alternatively, the third detection unit may determine whether the target person is seated in the first seat based on the detection signals of other detection devices, as described below.

[0198] The first adjusting unit adjusts the outward tilt angle of the first seat corresponding to the boarding position, which may mean that the first adjusting unit controls the seat driving device 100 connected to the first seat to operate so as to adjust the outward tilt angle of the first seat.

[0199] The second adjusting unit controls the first seat to be reset, which may mean that the second adjusting unit controls the seat driving device 100 connected to the first seat to operate so as to reset the first seat.

[0200] In one embodiment, the first detection unit includes a first detection sub-unit, a second detection sub-unit and a first judgment unit; the first detection sub-unit is used to detect whether there is a person within a predetermined range around the vehicle, wherein the person within the predetermined range is a target person; the second detection sub-unit is used to detect whether the target person has an action of reaching out to open the door when the first detection sub-unit detects that there is a person within the predetermined range around the vehicle; the first judgment unit is used to determine that the target person is going to get on the vehicle when the second detection sub-unit detects that the target person has an action of reaching out to open the door.

[0201] The first detection subunit can use radar to sense whether a person is within a predetermined range around the vehicle. Alternatively, the first detection subunit can control the vehicle's first camera to capture images of the vehicle's surroundings and determine whether a person is within the predetermined range based on the images captured by the first camera. If a person is present, the second detection subunit can track and capture the target person using the first camera to determine whether the target person is reaching out to open the door. If so, the first determination unit will determine that the target person is attempting to board the vehicle. Furthermore, the door that the target person is attempting to open is the location where they are attempting to board the vehicle.

[0202] In one embodiment, the welcome module further includes a posture detection unit and a retrieval unit. The posture detection unit is configured to detect the body posture information of the target person, including weight and height information, when the first detection subunit detects a person within a predetermined range around the vehicle. The retrieval unit is configured to retrieve pre-stored seat adaptive position information corresponding to the body posture information based on the body posture information. Furthermore, the first adjustment unit is configured to adjust the outward tilt angle of the first seat corresponding to the boarding position based on the seat adaptive position information.

[0203] It should be understood that the posture detection unit and the retrieval unit are also corresponding computer programs stored in the seat control device. The posture detection unit detecting the target person's posture information may mean that the posture detection unit determines the target person's posture information based on detection signals from corresponding detection devices. For example, the posture detection unit may control a corresponding camera (which may be the first camera) to capture the target person and obtain the target person's posture information based on the image information captured by the camera.

[0204] The retrieval unit is configured to retrieve pre-stored seat adaptive position information corresponding to the body posture information based on the body posture information. Subsequently, the first adjustment unit can adjust the outward tilt angle of the first seat corresponding to the boarding position based on the information retrieved by the retrieval unit. Furthermore, the seat control device may pre-store the corresponding body posture information and the seat adaptive position information corresponding to the body posture information for subsequent retrieval by the retrieval unit.

[0205] In one embodiment, the welcome module also includes a second judgment unit, which is used to detect whether the pressure and weight information of the side wings of the first seat meet the first predetermined requirements after adjusting the outward tilt angle of the first seat corresponding to the boarding position; if not, the first adjustment unit controls the first seat to continue to tilt outward until the pressure and weight information on the side wings of the first seat meet the first predetermined requirements.

[0206] The second determination unit detects whether the pressure on the first seat's wing and the weight information meet a first predetermined requirement. This may involve the second determination unit determining whether the relationship between the received pressure detection value of the first seat's wing and the target person's weight information (which may be obtained by the posture detection unit) meets the first predetermined requirement. The pressure on the first seat's wing is defined as F1, and the weight of the target person is defined as G. If F1 / G is greater than or equal to a set value, the relationship between the two is determined to meet the first predetermined requirement. The set value may be a value such as 0.4, 0.5, or 0.6.

[0207] In one embodiment, the third detection unit includes a third detection sub-unit and a third judgment unit; the third detection sub-unit is used to detect whether the opening angle of the door corresponding to the boarding position is getting smaller; the third judgment unit is used to determine that the target person has sat in the first seat when the third detection sub-unit detects that the opening angle of the door corresponding to the boarding position is getting smaller.

[0208] The third detection subunit detects whether the opening angle of the door corresponding to the boarding position is decreasing. This may include: the third detection subunit receives a detection signal from a door angle sensor and uses this signal to determine whether the opening angle of the door is decreasing. The door angle sensor is used to detect the opening angle of the door, and its type and installation method may be conventional.

[0209] In one embodiment, the third detection unit also includes a fourth detection subunit; the fourth detection subunit is used to detect whether the pressure on the first seat reaches a first value when the third detection subunit does not detect that the opening angle of the door corresponding to the boarding position is getting smaller; the fifth detection subunit is used to detect whether the duration of the scenario in which the pressure on the first seat reaches the first value reaches a second value when the fourth detection subunit detects that the pressure on the first seat reaches the first value; the third judgment unit is used to determine that the target person has sat on the first seat when the fifth detection subunit detects that the duration of the scenario in which the pressure on the first seat reaches the first value reaches a second value.

[0210] The fourth detection sub-unit detects whether the pressure applied to the first seat reaches the first value, which may mean that: the fourth detection unit receives the detection value F2 of the first pressure sensor as described above and the weight information of the target person (such as the gravity G of the target person), and compares the two. When F2 / G is greater than or equal to 0.4, it means that the pressure applied to the first seat reaches the first value. Of course, 0.4 can also be replaced by other values, such as 0.3 or 0.5; or, the first value can be a fixed value, and the fourth detection unit receives the detection value F2 of the first pressure sensor. When F2 is greater than or equal to the first value, it means that the pressure applied to the first seat reaches the first value, wherein the first value can be 300N, etc., and the value can be set by the user.

[0211] The fifth detection subunit detects whether the duration of a scenario in which the pressure applied to the first seat reaches the first value has reached a second value. This may involve the fifth detection subunit receiving a detection signal from a corresponding timer when the pressure applied to the first seat reaches the first value, and using this signal to determine whether the duration of the scenario in which the pressure applied to the first seat reaches the first value has reached the second value. The timer may start timing when the pressure applied to the first seat reaches the first value and stop timing when the pressure applied to the first seat falls below the first value. Alternatively, the timer may be a corresponding component within the seat control device.

[0212] Of course, the welcome module may further include other units to execute other control methods in the above-mentioned welcome mode.

[0213] In one embodiment, the first posture maintaining module includes a curve detection unit, a speed detection unit, and a third adjustment unit; the curve detection unit is configured to determine whether there is a curve within a preset range ahead of the vehicle; the speed detection unit is configured to determine whether the vehicle speed is greater than or equal to a predetermined value when the curve detection unit determines that there is a curve within the preset range ahead of the vehicle; and the third adjustment unit is configured to adjust the seat tilt direction and the seat tilt angle change speed according to the steering wheel rotation direction and the steering wheel angle change speed when the speed detection unit determines that the vehicle speed is greater than or equal to the predetermined value.

[0214] The curve detection unit determines whether there is a curve within a preset range in front of the vehicle, which may mean that: the curve detection unit can receive the detection signal of the corresponding detection device on the vehicle, and use it to determine whether there is a curve within the preset range in front of the vehicle. For example, the curve detection unit can receive image information within a predetermined range in front of the vehicle taken by the corresponding camera on the vehicle, and determine whether there is a curve within the preset range in front based on the image information.

[0215] The speed detection unit determines whether the vehicle speed is greater than or equal to a predetermined value, which may mean that the speed detection unit receives a detection signal from a corresponding detection device on the vehicle and uses it to determine whether the vehicle speed is greater than or equal to a predetermined value, wherein the detection device may be a speed sensor.

[0216] The third adjustment unit adjusts the seat's tilt direction and tilt angle change rate based on the steering wheel's rotational direction and steering wheel's angular change rate. This may mean that the third adjustment unit controls the seat drive device 100 based on the steering wheel's rotational direction and steering wheel's angular change rate to adjust the seat's tilt direction and tilt angle change rate. The steering wheel's rotational direction and steering wheel's angular change rate may be detected by a corresponding detection device on the vehicle. The detection device may transmit the detected steering wheel's rotational direction and steering wheel's angular change rate (i.e., the detection results) to the third adjustment unit, which then controls the seat drive device 100 based on these results to adjust the seat's tilt direction and tilt angle change rate. For the specific adjustment logic, reference may be made to the above description of the first posture control hold mode.

[0217] Of course, the first posture maintaining module may further include other units to execute other control methods in the above-mentioned first posture maintaining mode.

[0218] In one embodiment, the second posture maintaining module includes a road surface detection unit and a fourth adjustment unit; the road surface detection unit is used to determine whether the vehicle is located on a non-horizontal road surface on the left or right; the fourth adjustment unit is used to adjust the tilt direction and tilt angle of the seat according to the tilt direction and tilt angle of the vehicle when the road surface detection unit determines that the vehicle is located on a non-horizontal road surface on the left or right.

[0219] Among them, the road surface detection unit is used to determine whether the vehicle is located on the left or right non-horizontal road surface, which may mean: the road surface detection unit determines whether the vehicle is located on the left or right non-horizontal road surface based on the detection signal of the corresponding detection device on the vehicle. Among them, determining whether the vehicle is on the left or right non-horizontal road surface can be an existing technology. For example, the road surface detection unit can be based on the image captured by the camera on the vehicle (such as the first camera) to determine whether the vehicle enters the left or right non-horizontal road section.

[0220] The fourth adjustment unit adjusts the seat's tilt direction and tilt angle based on the vehicle's tilt direction and tilt angle. This may mean that the fourth adjustment unit controls the seat drive device 100 to adjust the tilt direction and tilt angle of the seat connected to the seat drive device 100 based on the vehicle's tilt direction and tilt angle. The vehicle's tilt direction and tilt angle may be detected by corresponding detection devices on the vehicle. The detection devices may transmit the detected vehicle's tilt direction and tilt angle (i.e., the detection results) to the fourth adjustment unit, which then controls the seat drive device 100 to adjust the tilt direction and tilt angle of the seat connected to the seat drive device 100. For the specific adjustment logic, reference may be made to the above description of the second posture control hold mode.

[0221] Of course, the second posture maintaining module may further include other units to execute other control methods in the above-mentioned second posture maintaining mode.

[0222] In one embodiment, the first cradle module includes a receiving unit and a fifth adjustment unit, the receiving unit being used to receive a first cradle mode activation instruction; the fifth adjustment unit being used to control the seat to swing left and right according to a preset first seat tilt angle and a preset first seat tilt change speed when the receiving unit receives the first cradle mode activation instruction.

[0223] The receiving unit receiving the first cradle mode activation instruction may mean that the receiving unit receives the first cradle mode activation instruction via a corresponding receiving device, wherein the receiving device may be a vehicle-mounted touch screen, etc. Of course, the receiving device may also be a voice receiving device such as a microphone.

[0224] The fifth adjustment unit controls the left and right swinging of the seat based on a preset first seat tilt angle and a preset first seat tilt changing speed. This may mean that the fifth adjustment unit controls the operation of the seat drive device 100 based on the preset first seat tilt angle and the preset first seat tilt changing speed to adjust the left and right swinging of the seat connected to the seat drive device 100. The preset first seat tilt angle and the preset first seat tilt changing speed may be pre-stored in the seat control device. Upon receiving the first cradle mode activation command, the fifth adjustment unit may retrieve this information and use it to control the operation of the seat drive device 100. For the specific adjustment logic, please refer to the above description of the first cradle mode.

[0225] Of course, the first cradle module may further include other units to execute other control methods in the above-mentioned first cradle mode.

[0226] In one embodiment, the second cradle mode includes an occupant detection unit, a heart rate detection unit and a sixth adjustment unit; the occupant detection unit is used to detect whether the occupant on the seat is a child or an elderly person; the heart rate detection unit is used to detect the occupant's heart rate when the occupant detection unit detects that the occupant on the seat is a child or an elderly person; the sixth adjustment unit is used to control the seat to swing left and right according to a preset second seat inclination angle and a preset second seat inclination change speed when the heart rate detection unit detects that the occupant's heart rate is greater than or equal to a predetermined value.

[0227] Among them, the occupant detection unit detects whether the occupant on the seat is a child or an elderly person, which may mean that the occupant detection unit receives detection information from the corresponding detection device on the vehicle, and uses this to determine whether the occupant on the chair is a child or an elderly person. For example, the occupant detection unit receives image information of the occupant on seat 200 taken by a camera on the vehicle (such as the second camera), and uses this to determine whether the occupant on the chair is a child or an elderly person. Among them, the specific judgment method may be the existing technology.

[0228] The heart rate detection unit detects the heart rate of the occupant, which may mean that the heart rate detection unit receives detection information from the corresponding detection device on the vehicle and obtains the heart rate of the occupant based on this. For example, the heart rate detection unit can receive the detection results of the millimeter wave radar in the vehicle and obtain the heart rate of the occupant based on this.

[0229] The sixth adjustment unit controls the left and right swinging of the seat based on a preset second seat tilt angle and a preset second seat tilt changing speed. This may mean that the sixth adjustment unit controls the seat drive device 100 to operate based on the preset second seat tilt angle and the preset second seat tilt changing speed, thereby adjusting the left and right swinging of the seat connected to the seat drive device 100. The preset second seat tilt angle and the preset second seat tilt changing speed may be pre-stored in the seat control device. When the occupant's heart rate is greater than or equal to a predetermined value, the sixth adjustment unit may call upon this information and use it to control the operation of the seat drive device 100. For the specific adjustment logic, please refer to the above description of the second cradle mode.

[0230] It should be understood that the second seat tilt angle may be the same as or different from the first seat tilt angle, and the second seat tilt change speed may be the same as or different from the first left and right tilt change speed.

[0231] Of course, the second cradle module may further include other units to execute other control methods in the above-mentioned second cradle mode.

[0232] The present invention also provides a vehicle, which, in addition to a seat 200 and the seat drive device 100 described in any one of the above embodiments, also includes an on-board controller, the on-board controller including a memory and a processor, the memory storing a computer program; the processor is used to execute the computer program to implement the seat 200 control method described in any one of the above embodiments.

[0233] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0234] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
