Seat and vehicle

Abstract

The application provides a seat and a vehicle. The seat comprises a body for a person to sit on, and a first driving mechanism comprising a first connecting member, a first actuating member and a first linkage member. The first connecting member is connected to the body and can rotate relative to the body about a first axis in a left-right direction or a front-rear direction. The first actuating member is connected to the first connecting member and can move relative to the first connecting member in a direction intersecting the first axis. The first linkage member is rotatably connected to the first actuating member, the first connecting member and the body, so as to convert the movement of the first actuating member into the swing of the body about the first axis. The body can compensate for inertial force when the vehicle is changing speed by swinging up and down, or compensate for centrifugal force when the vehicle is turning by swinging left and right. Thus, the riding experience can be improved.

Description

Technical Field

[0001] This application relates to the field of seating technology, and more particularly to a seat and a vehicle. Background Technology

[0002] When a vehicle changes gears, such as during braking or acceleration, especially during sudden braking or acceleration, a large inertial force is generated, which impacts passengers and affects riding safety. In addition, when a vehicle turns, especially during sharp turns, a large centrifugal force is generated, causing passengers to sway and reducing riding comfort.

[0003] Traditional vehicles and their seats cannot effectively solve the above-mentioned impact and shaking problems, affecting the riding experience.

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. 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.

[0046] In the description of this application, the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application.

[0047] In the description of this application, it should be understood that the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself. In addition, for the convenience of description, the orientation or positional relationship indicated by directional terms such as "front," "rear," "up," "down," "left," "right," "lateral," "vertical," "horizontal," and "top," "bottom," etc., is usually based on the orientation or positional relationship when the vehicle is in normal driving. Specifically, the direction of vehicle travel is the front-rear direction X, and the forward direction is "front," and the backward direction is "rear." The direction parallel to gravity is the up-down direction Z, and the direction in the same direction as gravity is "down," and the direction opposite to gravity is "up." The direction perpendicular to the front-rear direction X and the up-down direction Z is the left-right direction Y, and the left and right when facing "front" are "left" and "right," respectively.

[0048] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0049] To reduce the impact during gear shifting or the swaying during cornering and improve the riding experience, this application provides a seat.

[0050] Figures 1-12 An example of a seat in this application is shown.

[0051] See Figures 1-12 In this application, the seat 100 includes a body 1 and a first drive mechanism 2. The body 1 is for occupants to sit on. The first drive mechanism 2 includes a first connector 21 (which may be plate-shaped), a first actuator 22, and a first linkage 23. The first connector 21 is connected to the body 1 and can rotate relative to a first axis 61 in the front-rear direction X or the left-right direction Y. The first actuator 22 is connected to the first connector 21 and can move relative to the first connector 21 in a direction intersecting the first axis 61. The first linkage 23 is rotatably connected to the first actuator 22, the first connector 21, and the body 1 to convert the movement of the first actuator 22 into the swing of the body 1 around the first axis 61, so that the body 1 can compensate for the inertial force in the front-rear direction X by swinging up and down, or compensate for the centrifugal force when turning by swinging left and right.

[0052] Since the first drive mechanism 2 can drive the body 1 to swing up and down to compensate for the inertial force during gear shifting, reduce the impact during gear shifting, and improve riding safety, or drive the body 1 to swing left and right to compensate for the centrifugal force during turning, reduce the swaying during turning, and improve riding comfort, it can effectively improve the riding experience.

[0053] When the first axis 61 is along the left-right direction Y, the body 1 swings around the first axis 61 in a vertical swing (i.e., a swing along the vertical direction Z, i.e., pitch). This allows the first drive mechanism 2 to drive the body 1 to swing to a suitable angle in the vertical direction Z during gear shifting, such as during emergency braking or acceleration, depending on the gear shifting situation. This absorbs the inertial force during gear shifting, reduces impact, and prevents passengers from being ejected from the seat. For example, in the event of emergency braking causing the passenger to lurch forward, the body 1 can be driven to swing upward from its normal position (see [reference needed]). Figures 6 to 7 (During the change process), it prevents passengers from lurching forward, or, in the event of rapid acceleration causing passengers to lean backward, it drives the main body 1 to swing downward from its normal position, preventing passengers from leaning backward. This effectively improves riding safety and enhances the riding experience. This function of pitching the main body 1 to reduce impact can be called vibration damping.

[0054] When the first axis 61 is along the front-rear direction X, the body 1 swings around the first axis 61 in a left-right swing (i.e., swings in the left-right direction Y). This allows the first drive mechanism 2 to drive the body 1 to swing to a suitable angle in the left-right direction Y during turning, depending on the turning situation (see [reference needed]). Figures 11 to 12 The change process (of the body 1) compensates for the centrifugal force during turning, reducing passenger swaying, thus effectively improving ride comfort and enhancing the riding experience. This function of swaying the body 1 left and right to reduce swaying can be called a sway reduction function.

[0055] As can be seen, the first drive mechanism 2 has the function of vibration reduction or sway reduction. It can drive the main body 1 to swing up and down to compensate for the inertial force when the vehicle changes speed, or to swing left and right to compensate for the centrifugal force when the vehicle turns, effectively reducing the impact when changing speed or the shaking when turning, and improving the passenger riding experience.

[0056] Furthermore, the first drive mechanism 2 achieves vibration reduction or sway reduction through the cooperation between the first connecting member 21, the first actuator 22, and the first linkage 23, as well as with the body 1. The connection relationship between the first connecting member 21, the first actuator 22, the first linkage 23, and the body 1 forms a four-bar linkage mechanism. This method of achieving vibration reduction or sway reduction based on the four-bar linkage mechanism has a simple and compact structure, occupies less space, has high reliability, and only requires the first actuator 22 to move to drive the body 1 to swing up and down or left and right, which is convenient and efficient.

[0057] Among them, see Figure 4 and Figure 5 The connection points between the first connecting member 21 and the body 1, between the first linkage member 23 and the first connecting member 21, between the first linkage member 23 and the body 1, between the first linkage member 23 and the first actuating member 22, and between the first actuating member 22 and the first connecting member 21 are respectively referred to as the first connection point 41, the second connection point 42, the third connection point 43, the fourth connection point 44, and the fifth connection point 45. The first axis 61 is located at the first connection point 41. See also... Figures 4-7 When the first actuator 22 moves relative to the first connector 21, the first linkage 23 can rotate relative to the first actuator 22 around the fourth connection point 44 and relative to the first connector 21 around the second connection point 42, converting the movement of the first actuator 22 into the up-down or left-right swinging of itself and the body 1. For example, see [reference needed]. Figures 4-7 When the first axis 61 is along the left-right direction Y, if the first actuator 22 moves away from the first axis 61 relative to the first connector 21, the first linkage 23 can convert the movement of the first actuator 22 into an upward swing of itself and the body 1. In this way, during the vehicle's speed change or turning, it is only necessary to move the first actuator 22 relative to the first connector 21 to drive the body 1 to swing up and down or left and right, so as to reduce vibration or sway, which is convenient and efficient.

[0058] It is evident that the first drive mechanism 2, based on a relatively simple and compact structure, can efficiently and reliably reduce vibration or sway, effectively mitigating the impact during gear shifting or the shaking during cornering, thereby improving the passenger riding experience.

[0059] The first actuator 22 can take various structural forms, as long as it can be positioned relative to the first connecting member 21 in a direction intersecting the first axis (see...). Figure 4 and Figure 5 Move in the first direction (D) indicated by the center marker. See also: [This is one method.] Figures 3-5 In some embodiments, the first actuator 22 includes a first lead screw 221, and the first drive mechanism 2 further includes a first nut 24 and a first nut seat 25. The first nut seat 25 is rotatably connected to the first connector 21. The first nut 24 is disposed on the first nut seat 25 (for example, the first nut 24 and the first nut seat 25 are fixedly connected by welding or other means) and cooperates with the first lead screw 221 to drive the first lead screw 221 to move when the first lead screw 221 rotates.

[0060] The first lead screw 221 and the first nut 24 cooperate to form a lead screw and nut mechanism. Rotation of the first lead screw 221 allows for relative movement between the first lead screw 221 and the first nut 24 along the axial direction of the first lead screw 221. Since the first nut 24 is connected to the first connecting member 21 via the first nut seat 25, and the first connecting member 21 is rotatably connected to the body 1 and does not move along the axial direction of the first lead screw 221, the first nut 24 is constrained by the first connecting member 21 and also does not move along the axial direction of the first lead screw 221. That is, the first nut 24 and the first nut seat 25 constitute a first constraint member that does not move along the moving direction of the first actuator 22. Thus, when the first lead screw 221 rotates, the first nut 24 does not move along the axial direction of the first lead screw 221, but instead acts on the first lead screw 221, allowing the first lead screw 221 to rotate around its own axis while simultaneously moving along the axial direction of the first lead screw 221 under the reaction force of the first nut 24, thereby generating movement relative to the first connecting member 21. In this case, simply moving the first actuator 22 along the direction intersecting the first axis 61 along the axis of the first lead screw 221 will achieve vibration reduction or sway reduction. It can be understood that, at this time, the direction of movement of the first actuator 22 (i.e., the first direction D) is the axial direction of the first lead screw 221.

[0061] As can be seen, the first lead screw 221 and the first nut 24 can conveniently realize the movement of the first actuator 22 relative to the first connecting member 21. Moreover, the movement of the first actuator 22 relative to the first connecting member 21 based on the cooperation of the first lead screw 221 and the first nut 24 also has the advantages of high precision, good reliability and good self-locking performance. It can conveniently, accurately and reliably control the swing of the body 1 to and maintain the desired angle position, more effectively reduce vibration or sway, reduce the impact during gear change or the swaying during turning, and improve the passenger riding experience. It can be understood that in this case, the first actuator 22 (specifically the first lead screw 221) is connected to the first connecting member 21 through the first nut 24 and the first nut seat 25, and the connection between the first actuator 22 and the first connecting member 21 is a rotational connection. The connection point between the two (i.e., the fifth connection point 45) is also a rotational connection point, just like the other four connection points (i.e., the first connection point 41, the second connection point 42, the third connection point 43 and the fourth connection point 44).

[0062] The rotation of the first lead screw 221 about its own axis can be driven by a motor. For example, see... Figures 3-5 The first actuator 22 also includes a first motor 222, which is driven by the first lead screw 221 to drive the lead screw 221 to rotate. In this case, the first motor 222 not only drives the first lead screw 221 to rotate, but also moves with the first lead screw 221, making it easier to drive the first lead screw 221 to rotate and move simultaneously. At this time, the first actuator 22 can directly adopt a lead screw motor structure to further improve the structural compactness and reliability, and simplify the assembly process.

[0063] The output shaft of the first motor 222 and the first lead screw 221 may be collinear, or they may not be collinear but intersect. Specifically, when the output shaft of the first motor 222 intersects the axis of the first lead screw 221, see [reference needed]. Figures 3-5 The first actuator 22 is shorter in the first direction D, which not only makes it easier to avoid the original structural components of the seat 100 and reduce interference, but also helps to reduce the size of the seat 100 in the front-back direction X or the left-right direction Y, improve the swing stability of the seat 100 and improve the riding experience.

[0064] As an example of the first linkage 23 in the foregoing embodiments, see Figures 2-5The first linkage 23 includes a first support 231, a first crossbar 232, and two first swing arms 233. The first support 231 is rotatably connected to the first actuator 22 so that the first linkage 23 is rotatably connected to the first actuator 22. The first support 231 is also rotatably connected to the first connector 21 so that the first linkage 23 is rotatably connected to the first connector 21. The first crossbar 232 is fixedly connected to the first support 231 (e.g., welded). The two first swing arms 233 are rotatably connected to the opposite ends of the first crossbar 232 and are rotatably connected to the body 1 respectively so that the first linkage 23 is rotatably connected to the body 1.

[0065] Based on the above configuration, the first linkage 23 can be rotatably connected to the first connecting member 21, the first actuator 22, and the main body 1. This allows the first linkage 23 to convert the movement of the first actuator 22 into the swinging of the main body 1 around the first axis 61, achieving vibration reduction or sway reduction. Moreover, the first linkage 23 is rotatably connected to the opposite ends of the main body 1 via two first swing arms 233, and the two first swing arms 233 are connected by a first crossbar 232. This allows for a smoother drive of the main body 1 to swing around the first axis 61, achieving a smoother vibration reduction or sway reduction process and more effectively improving the riding experience.

[0066] The first horizontal bar 232 can be a straight bar, or it can be a curved bar, a broken bar, or other non-straight bar structure. For example, see... Figures 3-5 In some embodiments, the first crossbar 232 includes a first segment 234 and two second segments 235. The first segment 234 is connected between the two second segments 235 and is close to the first axis 61 relative to the two second segments 235 in the direction of movement of the first actuator 22 (i.e., in the first direction D). In this case, the first crossbar 232 is a non-straight bar structure, and the middle part of the first crossbar 232 protrudes towards the first axis 61 relative to both ends, making the first crossbar 232 roughly "U"-shaped. This facilitates the first crossbar 232 to avoid other structural components, reduces collisions between the first crossbar 232 and other structural components during swinging, and helps to achieve a smoother and more stable vibration reduction or sway reduction process, thereby more effectively improving the riding experience.

[0067] Additionally, see Figures 3-5In some embodiments, the end of the first swing arm 233 connected to the body 1 is closer to the first axis 61 in the direction of movement of the first actuator 22 than the end of the first swing arm 233 connected to the first crossbar 232. This not only facilitates the rotational connection of the two first swing arms 233 to the opposite ends of the body 1, converting the movement of the first actuator 22 into the swing of the body 1 around the first axis 61 to achieve vibration reduction or sway reduction, but also facilitates the two first swing arms 233 to avoid other structural components, reducing collisions between the two first swing arms 233 and other structural components during the swinging process, achieving a smoother and more stable vibration reduction or sway reduction process, and more effectively improving the riding experience.

[0068] In the foregoing embodiments, the first linkage 23 can be connected to the end of the first actuator 22 that is away from the first axis 61. In this way, the connection point between the first linkage 23 and the body 1 (i.e., the third connection point 43) is farther away from the first axis 61 in the direction of movement of the first actuator 22, which can drive the body 1 to swing around the first axis 61 more smoothly, and facilitates the first linkage 23 to avoid other structural components, reducing the collision between the first linkage 23 and other structural components during the swinging process, realizing a smoother and more stable vibration reduction or sway reduction process, and more effectively improving the riding experience.

[0069] See Figure 1 and Figure 2 The main body 1 typically includes a seat 12 and a backrest 11. The seat 12 is for people to sit on, and the backrest 11 is connected to the rear end of the seat 12 for people to lean against. The connection between the first drive mechanism 2 and the main body 1 can specifically be the connection between the first drive mechanism 2 and the seat 12. That is, the connection between the first connecting member 21 and the first linkage member 23 and the main body 1 can both be the connection between them and the seat 12. In other words, the first connection point 41 and the third connection point 43 are the connection points between the first connecting member 21 and the seat 12, and between the first linkage member 23 and the main body 1, respectively.

[0070] Here, we take the first drive mechanism 2 to achieve the vibration reduction function as an example to explain the connection relationship between the first drive mechanism 2 and the base 12.

[0071] When the first drive mechanism 2 achieves vibration reduction, see Figures 2-5 In some embodiments, the first connecting member 21 of the first driving mechanism 2 is connected to the rear end of the base 12, while the first linkage member 23 of the first driving mechanism 2 is connected to the front position of the left and right ends of the base 12.

[0072] Specifically, see Figures 2-5In some embodiments, the seat 12 includes two side plates 13, a front rod 14 and a rear rod 15. The two side plates 13 are arranged opposite each other in the left-right direction Y. The front rod 14 and the rear rod 15 are respectively connected to the front end and the rear end of the two side plates 13. The first connecting member 21 is rotatably connected to the rear rod 15, and the first linkage member 23 is rotatably connected to the front end of the two side plates 13.

[0073] More specifically, to facilitate the rotatable connection between the first connecting member 21 and the rear rod 15, see [reference needed]. Figures 3-5 The main body 1 also includes a first connecting arm 16, which is inclined downward and forward. Its upper end is fixedly connected to the rear rod 15 (e.g., welded), and its lower end is inclined forward relative to the upper end and rotatably connected to the first connecting member 21 at the first connection point 41. In order to facilitate the rotatable connection between the first linkage member 23 and the front end of the two side plates 13, the first linkage member 23 is rotatably connected to the front end of the two side plates 13 respectively through the two first swing arms 233 mentioned above, and the connection points between the two first swing arms 233 and the front end of the two side plates 13 (i.e., the two third connection points 43) are located on the rear side of the front rod 14.

[0074] Based on the above configuration, the first drive mechanism 2 can convert the movement of the first actuator 22 along the front-back direction X into the swing of the body 1 around the first axis 61 along the left-right direction Y, so as to realize the up-and-down swing of the body 1 for vibration reduction.

[0075] As a further improvement to the foregoing embodiments, see Figures 1-2 as well as Figures 8-12 In some embodiments, the seat 100 includes not only the body 1 and the first drive mechanism 2, but also a second drive mechanism 3. The second drive mechanism 3 is disposed below the first drive mechanism 2 and includes a bracket 37, a second connecting member 31 (which may be plate-shaped), a second actuator 32, and a second linkage member 33. The bracket 37 is connected to the first linkage member 23 (e.g., through a means of communication). Figure 4 The support leg 26 shown is connected. The second connecting member 31 is connected to the bracket 37 and can rotate relative to the second axis 62 perpendicular to the first axis 61. The second actuator 32 is connected to the second connecting member 31 and can move relative to the second connecting member 31 in a direction intersecting the second axis 62. The second linkage 33 is rotatably connected to the second actuator 32, the second connecting member 31 and the bracket 37 to convert the movement of the second actuator 32 into the swing of the body 1 around the second axis 62.

[0076] Since the second drive mechanism 3 can drive the body 1 to swing around the second axis 62, and the second axis 62 is perpendicular to the first axis 61, that is, the first axis 61 and the second axis 62 are respectively along one of the left-right direction Y and the other of the front-back direction X, when the first drive mechanism 2 drives the body 1 to swing up and down to reduce vibration, the second drive mechanism 3 can drive the body 1 to swing left and right to reduce sway. And when the first drive mechanism 2 drives the body 1 to swing left and right to reduce sway, the second drive mechanism 3 can drive the body 1 to swing up and down to reduce vibration. In other words, the first drive mechanism 2 and the second drive mechanism 3 can achieve one of the functions of vibration reduction and sway reduction. In this way, the body 1 can both reduce vibration to improve the safety of the vehicle during gear shifting and reduce sway to improve the comfort of the vehicle during cornering. Therefore, it can more effectively improve the passenger riding experience.

[0077] In this configuration, with the first axis 61 aligned with the left-right direction Y and the second axis 62 aligned with the front-back direction X, the body 1 swings around the second axis 62 in a left-right motion (i.e., a swing along the left-right direction Y). This allows the second drive mechanism 3 to drive the body 1 to swing to a suitable angle in the left-right direction Y during a turn (e.g., a sharp turn), depending on the turning situation (see [reference needed]). Figures 11 to 12 (The change process) compensates for the centrifugal force during the turning process, reduces passenger swaying, improves riding comfort, and enhances the riding experience.

[0078] With the first axis 61 aligned along the longitudinal direction X, and the second axis 62 aligned along the lateral direction Y, the body 1 swings about the first axis 61 in a vertical direction (i.e., a vertical swing along the vertical direction Z, i.e., pitch). This allows the first drive mechanism 2 to drive the body 1 to swing to a suitable angle in the vertical direction Z during gear changes, such as during emergency braking or acceleration (see [reference]). Figures 6 to 7 (The change process) absorbs the inertial force during the speed change process, reduces impact, prevents passengers from falling off the seat, improves riding safety, and enhances the riding experience.

[0079] As can be seen, the second drive mechanism 3 can reduce swaying while the first drive mechanism 2 is reducing vibration, or reduce swaying while the first drive mechanism 2 is reducing swaying. Thus, together with the first drive mechanism 2, it can achieve the functions of vibration reduction and swaying reduction, effectively reducing the impact during gear shifting and the shaking during cornering, and improving the riding experience.

[0080] Furthermore, the second drive mechanism 3 achieves the function of sway reduction or vibration reduction through the cooperation between the second connector 31, the second actuator 32, the second linkage 33 and the bracket 37. The connection relationship between the second connector 31, the second actuator 32, the second linkage 33 and the bracket 37 forms a four-bar linkage mechanism. This method of achieving sway reduction or vibration reduction based on the four-bar linkage mechanism has a simple and compact structure, occupies less space, has high reliability, and only requires the second actuator 32 to move to drive the bracket 37 and the body 1 to swing left and right or up and down, which is convenient and efficient.

[0081] The first drive mechanism 2 and the second drive mechanism 3 form a double-layer four-bar linkage mechanism, which enables the seat 100 to perform up-and-down swing vibration reduction and left-and-right swing sway reduction under the drive of the double-layer four-bar linkage mechanism.

[0082] Among them, see Figure 9 and Figure 10 The connection points between the second connecting member 31 and the bracket 37, between the second linkage member 33 and the second connecting member 31, between the second linkage member 33 and the bracket 37, between the second linkage member 33 and the second actuator 32, and between the second actuator 32 and the second connecting member 31 are respectively referred to as the first engagement point 51, the second engagement point 52, the third engagement point 53, the fourth engagement point 54, and the fifth engagement point 55. When the second actuator 32 moves relative to the second connecting member 31, see... Figures 9-12 The second linkage 33 can rotate relative to the second actuator 32 around the fourth engagement point 54, and rotate relative to the second connector 31 around the second engagement point 52, converting the movement of the second actuator 32 into left-right or up-down swinging of itself, the bracket 37, the first drive mechanism 2, and the body 1. For example, see [link to relevant documentation]. Figures 9-10 When the second axis 62 is along the front-rear direction X, if the second actuator 32 moves relative to the second connector 31 in a direction away from the second axis 62 located at the first joint point 51, the second linkage 33 can convert the movement of the second actuator 32 into the swinging of itself, the bracket 37, the first drive mechanism 2 and the body 1 along the left-right direction Y. In this way, during the vehicle turning or speed change, it is only necessary to move the second actuator 32 relative to the second connector 31 to drive the body 1 to swing left and right or up and down to reduce sway or vibration, which is convenient and efficient.

[0083] It is evident that the second drive mechanism 3, based on a relatively simple and compact structure, can efficiently and reliably reduce swaying or vibration, effectively mitigating the shaking during turns or the impact during gear changes, thus improving the passenger riding experience.

[0084] The second actuator 32 can take various structural forms, as long as it can be positioned relative to the second connecting member 31 in a direction intersecting the second axis 62 (see...). Figure 10 Move in the second direction (L) indicated by the center mark. See also one method. Figures 8-10 In some embodiments, the second actuator 32 includes a second lead screw 321, and the second drive mechanism 3 further includes a second nut 34 and a second nut seat 35. The second nut seat 35 is rotatably connected to the second connector 31. The second nut 34 is disposed on the second nut seat 35 (for example, the second nut 34 and the second nut seat 35 are fixedly connected by welding or other means) and cooperates with the second lead screw 321 to drive the second lead screw 321 to move when the second lead screw 321 rotates.

[0085] The second lead screw 321 and the second nut 34 cooperate to form a lead screw and nut mechanism. Rotation of the second lead screw 321 allows for relative movement of the second lead screw 321 and the second nut 34 along the axial direction of the second lead screw 321. Since the second nut 34 is connected to the second connecting member 31 via the second nut seat 35, and the second connecting member 31 is rotatably connected to the bracket 37 and does not move along the axial direction of the second lead screw 321, the second nut 34 is constrained by the second connecting member 31 and also does not move along the axial direction of the second lead screw 321. That is, the second nut 34 and the second nut seat 35 constitute a second constraint member that does not move along the moving direction of the second actuator 32. Thus, when the second lead screw 321 rotates, the second nut 34 does not move along the axial direction of the second lead screw 321, but instead acts on the second lead screw 321, allowing the second lead screw 321 to rotate around its own axis while simultaneously moving along the axial direction of the second lead screw 321 under the reaction force of the second nut 34, thereby generating movement relative to the second connecting member 31. In this case, simply moving the second actuator 32 along the direction intersecting the second axis 62 along the axis of the second lead screw 321 will achieve sway reduction or vibration reduction. It can be understood that, at this time, the direction of movement of the second actuator 32 (i.e., the second direction L) is the axial direction of the second lead screw 321.

[0086] As can be seen, the second lead screw 321 and the second nut 34 can conveniently realize the movement of the second actuator 32 relative to the second connecting member 31. Moreover, the movement of the second actuator 32 relative to the second connecting member 31 based on the cooperation of the second lead screw 321 and the second nut 34 also has the advantages of high precision, good reliability and good self-locking performance. It can conveniently, accurately and reliably control the swing of the body 1 to and maintain the desired angle position, more effectively reduce swaying or vibration, reduce the swaying during turning or the impact during speed change, and improve the passenger riding experience. It can be understood that in this case, the second actuator 32 (specifically the second lead screw 321) is connected to the second connecting member 31 through the second nut 34 and the second nut seat 35, and the connection between the second actuator 32 and the second connecting member 31 is a rotational connection. The engagement point between the two (i.e., the fifth engagement point 55) is also a rotational connection point, just like the other four engagement points (i.e., the first engagement point 51, the second engagement point 52, the third engagement point 53 and the fourth engagement point 54).

[0087] The rotation of the second lead screw 321 about its own axis can be driven by a motor. For example, see... Figures 8-10 The second actuator 32 also includes a second motor 322, which is driven by the second lead screw 321 to drive the lead screw 321 to rotate. In this case, the second motor 322 not only drives the second lead screw 321 to rotate, but also moves with the second lead screw 321, making it easier to drive the second lead screw 321 to rotate and move simultaneously. At this time, the second actuator 32 can directly adopt a lead screw motor structure to further improve the structural compactness and reliability, and simplify the assembly process.

[0088] The output shaft of the second motor 322 and the second lead screw 321 can be collinear, or they can be non-collinear and intersect. Specifically, when the output shaft of the second motor 322 intersects the axis of the second lead screw 321, see [reference needed]. Figures 8-10 The second actuator 32 is shorter in the second direction L, which not only makes it easier to avoid the original structural components of the seat 100 and reduce interference, but also helps to reduce the size of the seat 100 in the left-right direction Y or the front-back direction X, improve the swing stability of the seat 100 and improve the riding experience.

[0089] As an example of the second linkage 33 in the foregoing embodiments, see Figure 2 as well as Figures 8-10The second linkage 33 includes a second support 331, a second crossbar 332, and two second swing arms 333. The second support 331 is rotatably connected to the second actuator 32 so that the second linkage 33 is rotatably connected to the second actuator 32. The second support 331 is also rotatably connected to the second connector 31 so that the second linkage 33 is rotatably connected to the second connector 31. The second crossbar 332 is fixedly connected to the second support 331 (e.g., welded). The two second swing arms 333 are rotatably connected to the opposite ends of the second crossbar 332 and are rotatably connected to the bracket 37 so that the second linkage 33 is rotatably connected to the bracket 37.

[0090] Based on the above configuration, the second linkage 33 can be rotatably connected to the second connecting member 31, the second actuator 32, and the bracket 37. This allows the second linkage 33 to convert the movement of the second actuator 32 into the swinging of the bracket 37 around the second axis 62, achieving a rocking or vibration reduction function. Furthermore, the second linkage 33 is rotatably connected to the opposite ends of the bracket 37 via two second swing arms 333, and the two second swing arms 333 are connected by a second crossbar 332. This allows for a smoother drive of the bracket 37 to swing around the second axis 62, achieving a more stable rocking or vibration reduction process and more effectively improving the riding experience.

[0091] The second horizontal bar 332 can be a straight bar, or it can be a curved bar, a broken bar, or other non-straight bar structure. For example, see... Figures 8-10 In some embodiments, the second crossbar 332 includes a first rod 334 and two second rods 335. The first rod 334 is connected between the two second rods 335 and is close to the second axis 62 relative to the two second rods 335 in the direction of movement of the second actuator 32 (i.e., in the second direction L). In this case, the second crossbar 332 is a non-straight rod structure, and the middle part of the second crossbar 332 protrudes towards the second axis 62 relative to both ends, making the second crossbar 332 roughly "U"-shaped. This facilitates the second crossbar 332 to avoid other structural components, reduces collisions between the second crossbar 332 and other structural components during swinging, and helps to achieve a smoother and more stable sway or vibration reduction process, thereby more effectively improving the riding experience.

[0092] Additionally, see Figures 8-10In some embodiments, the end of the second swing arm 333 connected to the bracket 37 is closer to the second axis 62 in the direction of movement of the second actuator 32 than the end of the second swing arm 333 connected to the second crossbar 332. This not only facilitates the rotatable connection between the two second swing arms 333 and the opposite ends of the bracket 37, converting the movement of the second actuator 32 into the swinging of the body 1 around the second axis 62 to achieve sway reduction or vibration reduction, but also facilitates the two second swing arms 333 avoiding other structural components, reducing collisions between the two second swing arms 333 and other structural components during the swinging process, achieving a smoother and more stable sway reduction or vibration reduction process, and more effectively improving the riding experience.

[0093] See also Figure 8 In some embodiments, the second linkage 33 further includes a connecting rod 336, which is connected between the two second swing arms 333. Specifically, it is connected between the ends of the two second swing arms 333 that are connected to the bracket 37, that is, between the two third joint points 53. This can further enhance the structural reliability and swing stability.

[0094] In the aforementioned embodiments, the second linkage 33 can be connected to the end of the second actuator 32 that is away from the second axis 62. In this way, the connection point (i.e., the third engagement point 53) between the second linkage 33 and the bracket 37 is farther away from the second axis 62 in the direction of movement of the second actuator 32, which can drive the body 1 to swing around the second axis 62 more smoothly, and facilitates the second linkage 33 to avoid other structural components, reducing the collision between the second linkage 33 and other structural components during the swinging process, realizing a smoother and more stable sway or vibration reduction process, and more effectively improving the riding experience.

[0095] The second connecting member 31 and the second linkage member 33 of the second drive mechanism 3 can be connected to the opposite ends of the bracket 37 along the left-right direction Y or the front-back direction X to drive the body 1 to swing left and right or up and down.

[0096] Here, we take the second drive mechanism 3 to realize the anti-sway function as an example to explain the connection relationship between the second drive mechanism 3 and the bracket 37.

[0097] See Figure 2 as well as Figures 8-12 In some embodiments, when the second drive mechanism 3 achieves the anti-sway function, the second connecting member 31 of the second drive mechanism 3 is connected to the left end of the bracket 37, and the second linkage member 33 of the second drive mechanism 3 is connected to the right side of the front and rear ends of the bracket 37, so that the second connecting member 31 and the second linkage member 33 are respectively connected to the left end and the right end of the bracket 37.

[0098] Specifically, see Figure 2 as well as Figures 8-12In some embodiments, the bracket 37 includes two end plates 371, a left rod 372 and a right rod 373. The two end plates 371 are arranged opposite each other in the front-rear direction X. The left rod 372 and the right rod 373 are respectively connected to the left and right ends of the two end plates 371. The second connector 31 is rotatably connected to the left rod 372, and the second linkage 33 is rotatably connected to the right end of the two end plates 371.

[0099] More specifically, to facilitate the rotatable connection between the second connector 31 and the left rod 372, see [reference needed]. Figure 2 as well as Figures 8-12 The bracket 37 also includes a second connecting arm 38, which is tilted downward and to the right. Its upper end is fixedly connected to the left rod 372 (e.g., welded), and its lower end is tilted to the right relative to the upper end and rotatably connected to the second connecting member 31 at the first engagement point 51. In order to facilitate the rotatable connection between the second linkage member 33 and the two end plates 371, the second linkage member 33 is rotatably connected to the right end of the two end plates 371 respectively through the two second swing arms 333 mentioned above, and the connection points between the two second swing arms 333 and the right end of the two end plates 371 (i.e., the two third engagement points 53) are located on the left side of the right rod 373.

[0100] Based on the above configuration, the second drive mechanism 3 can convert the movement of the second actuator 32 in the left-right direction Y into the swing of the body 1 around the second axis 62 in the front-back direction X, thereby realizing the left-right swing of the body 1 to reduce sway.

[0101] Additionally, this application also provides a vehicle that includes the seat 100 of any embodiment. Specifically, the vehicle can be various vehicles such as automobiles or construction vehicles.

[0102] 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, all of which should be covered within the scope of the technical solutions claimed in this application.
