Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a seat and a vehicle. Background Technology

[0002] The comfort of a vehicle seat is closely related to its firmness. Based on research on human muscles and bones, a softer seat can improve the initial comfort of sitting. However, prolonged sitting cannot guarantee the "S-shaped" physiological curvature of the spine, leading to abnormal lumbar curvature and causing fatigue.

[0003] Passengers vary in age, height, and body type, resulting in different preferences for seat firmness. The duration of each ride also influences the desired firmness; for example, shorter journeys generally require a softer seat, while longer journeys necessitate a firmer one. However, the firmness of seats is fixed at the factory, preventing passengers from adjusting it to their liking and impacting their overall comfort. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a seat and vehicle capable of adjusting the firmness of the seat.

[0005] In a first aspect, this utility model provides a seat, the seat comprising:

[0006] A cushion having a face and a back facing away from each other along its own thickness;

[0007] The squeezing mechanism is located on the side of the back away from the face. The squeezing mechanism is used to squeeze the soft pad in the direction from the back towards the face.

[0008] A tensioning element, connected to the face, is used to tighten the face in a direction from the face to the back when the squeezing mechanism squeezes the pad.

[0009] The seat according to the embodiment of this utility model has at least the following beneficial effects:

[0010] By incorporating a compression mechanism, the cushion is compressed and deformed when it is pressed against the face from the back. This reduces the cushion's thickness and increases its density, allowing it to harden. Simultaneously, the compression force compresses or deforms the face in the direction from the back to the face. A tensioning element, on the other hand, pulls the face in the direction from the face to the back, tightening it to resist the facial movement or deformation caused by the compression mechanism. In other words, the compression mechanism and tensioning element apply forces to the cushion in opposite directions, resulting in a more compact cushion structure. This makes it easier for the cushion to harden, achieving the desired firmness more readily, thus improving the seat's adjustable firmness and enhancing the occupant's comfort.

[0011] According to an embodiment of the present invention, the seat has a compression mechanism including a drive assembly and a compression plate. The compression plate is connected to the drive assembly, and the drive assembly is used to drive the compression plate to compress the cushion in the direction from the back to the face.

[0012] According to an embodiment of the present invention, the drive assembly of the seat includes a mounting base, a support member, a drive rod, and a push block. The first end of the support member is rotatably connected to the mounting base, and the second end of the support member is connected to the extrusion plate. The drive rod is connected to the push block, and the push block is connected to the support member. The drive rod is used to drive the push block to move along its own axial direction so that the push block pushes the support member to rotate around the first end.

[0013] According to the embodiment of the present utility model, the seat has two support members and two push blocks. The drive rod is rotatably connected to the mounting base. The two ends of the drive rod are respectively provided with a first threaded part and a second threaded part. The spiral directions of the first threaded part and the second threaded part are opposite. The two push blocks are respectively threadedly connected to the first threaded part and the second threaded part. The second ends of the two support members abut against the extrusion plate. The side of the two support members that is away from each other abuts against the two push blocks.

[0014] According to the embodiment of the present utility model, the support member of the seat extends in an arc shape along the direction from the first end to the second end, and the center of the arc is located on the side of the support member away from the push block it abuts.

[0015] According to the embodiment of the present utility model, the seat has a push block defining a limiting groove, and the support member is limited to the limiting groove. The limiting groove is used to restrict the axial movement of the support member relative to the push block at the rotational connection of the second end.

[0016] According to an embodiment of the present utility model, the seat further includes a frame, a base, and a backrest, with the base and backrest respectively disposed on the frame;

[0017] The base is equipped with a cushion, a compression mechanism, and a tensioning element. The third end of the compression plate is rotatably connected to the frame, and the fourth end of the compression plate is connected to the drive assembly. The third end is positioned relative to the cushion away from the backrest, and the fourth end is positioned relative to the cushion near the backrest; and / or,

[0018] The backrest is equipped with a soft pad, a compression mechanism and a tensioning component. The third end of the compression plate is rotatably connected to the frame, and the fourth end of the compression plate is connected to the drive assembly. The third end is located near the base of the soft pad, and the fourth end is located away from the base of the soft pad.

[0019] According to an embodiment of the present invention, the seat has its face connected to tensioning members on both sides along the width direction of the cushion.

[0020] According to an embodiment of the present invention, the seat further includes a frame, the frame including a tensioning member disposed on the side of the back away from the face;

[0021] The tensioning element is a flexible element, which includes a first section, a second section, and a third section. The first section, the second section, and the third section are connected in sequence. The second section is wrapped around the tensioning element. The first section and the third section are respectively located on both sides of the width direction of the pad, and both the first section and the third section are connected to the face.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0044] like Figure 1 As shown, this utility model embodiment provides a seat 100, which can be applied to vehicles or everyday furniture.

[0045] The seat 100 includes a cushion 10, a compression mechanism 20, and a tensioning member 30. The cushion 10 has a face 101 and a back 102 facing away from each other along its thickness direction H, wherein the face 101 is closer to the human body than the back 102. The compression mechanism 20 is disposed on the side of the back 102 opposite to the face 101, and is used to compress the cushion 10 in the direction from the back 102 towards the face 101. The tensioning member 30 is connected to the face 101, and is used to tighten the face 101 in the direction from the face 101 towards the back 102 when the compression mechanism 20 compresses the cushion 10.

[0046] In this embodiment of the invention, by providing a compression mechanism 20, when the compression mechanism 20 compresses the soft pad 10 in the direction from the back 102 to the face 101, the soft pad 10 can undergo compression deformation, thereby reducing the thickness of the soft pad 10 and increasing its density, making the soft pad 10 harden. Simultaneously, the compression action of the compression mechanism 20 forces the face 101 to undergo a certain movement or deformation in the direction from the back 102 to the face 101. Furthermore, by providing a tensioning member 30, the tensioning member 30 can move in the direction from the face 101 to the back 102. The direction of 02 pulls on the face 101, causing the face 101 to tighten. This resists the movement or deformation of the face 101 along the back 102 towards the face 101 when the squeezing mechanism 20 squeezes the cushion 10. That is, the squeezing mechanism 20 and the tensioning member 30 apply force to the cushion 10 in opposite directions, making the structure of the cushion 10 more compact. As a result, the cushion 10 is easier to change from soft to hard, thus making it easier to achieve the desired firmness. The firmness adjustment effect of the seat 100 is better, improving the riding experience of the occupant.

[0047] like Figure 1 As shown, in some embodiments, the cushion 10 has a multi-layer composite structure, including a face cover 11, soft foam 12, and foam 13. The face cover 11, soft foam 12, and foam 13 are stacked sequentially along the thickness direction H of the cushion 10. The face cover 11 is used for contact with the human body, and the face cover 11 is located on the side where the face 101 is located; the soft foam 12 is used for auxiliary support, and it can absorb a small part of the pressure generated when the occupant sits; the foam 13 is used for main support, and it can absorb most of the pressure generated when the occupant sits, and the foam 13 is located on the side where the back 102 is located.

[0048] In its natural state, the soft foam 12 and foam 13 are in a certain fluffy state. When the occupant sits on the seat 100, the soft foam 12 and foam 13 can be compressed to a certain extent under the weight of the occupant, providing the occupant with a relatively soft sitting feel. When the compression mechanism 20 compresses the cushion 10 in the direction from the foam 13 to the cover 11, the thickness of the soft foam 12 and foam 13 decreases and its density increases, making the cushion 10 change from soft to hard. At the same time, the tensioning member 30 pulls the cover 11 in the direction from the cover 11 to the foam 13, causing the cover 11 to tighten.

[0049] In some other embodiments, the specific structure of the cushion 10 can be set according to actual needs. This utility model embodiment does not limit the specific structure of the cushion 10. For example, the cushion 10 can also be a single-layer structure.

[0050] In some other embodiments, an additional padding layer for contact with the human body may be provided on the side of the face mask 11 opposite to the foam 13.

[0051] like Figure 1 and Figure 2 As shown, in some embodiments, the extrusion mechanism 20 includes a drive assembly 21 and an extrusion plate 22. The extrusion plate 22 is connected to the drive assembly 21, which drives the extrusion plate 22 to extrude the pad 10 in the direction from the back 102 to the face 101. By using a plate-structured extrusion plate 22 to extrude the pad 10, a large contact area can be formed between the extrusion plate 22 and the pad 10, resulting in a larger compressible area for the pad 10. This allows the extrusion mechanism 20 to adjust the hardness of a larger area of ​​the pad 10. Furthermore, the surface-to-surface contact between the plate-structured extrusion plate 22 and the pad 10 is good, which is beneficial for the extrusion mechanism 20 to adjust the hardness of the pad 10.

[0052] like Figure 2 and Figure 3 As shown, in some embodiments, the drive assembly 21 includes a mounting base 211, a support member 212, a drive rod 213, and a push block 214. A first end 212a of the support member 212 is rotatably connected to the mounting base 211, and a second end 212b of the support member 212 is connected to the extrusion plate 22. The drive rod 213 is connected to the push block 214, and the push block 214 is connected to the support member 212. The drive rod 213 drives the push block 214 to move along its own axial direction, causing the push block 214 to push against the support member 212 as it rotates around its first end 212a, thereby enabling the second end 212b to push against the extrusion plate 22 in the direction from the back 102 to the face 101.

[0053] The first end 212a and the second end 212b are the two ends of the support member 212 along its length.

[0054] In this embodiment, the axial movement of the push block 214 along the drive rod 213 is converted into the rotational movement of the support member 212, so that the second end 212b of the support member 212 pushes against the extrusion plate 22. Compared with the method of directly using a single linear movement to push against the extrusion plate 22, this embodiment can reduce the movement space required for the support member 212 to push against the extrusion plate 22 in the direction from the back 102 to the face 101 while the extrusion plate 22 compresses the pad 10 and produces the same amount of compression. This makes the overall structure of the drive assembly 21 more compact and reduces the space required to install the drive assembly 21.

[0055] like Figure 2 and Figure 3As shown, in some embodiments, there are two support members 212 and two push blocks 214. A drive rod 213 is rotatably connected to the mounting base 211. The two ends of the drive rod 213 are respectively provided with a first threaded portion and a second threaded portion, with opposite helical directions. The two push blocks 214 are threadedly connected to the first threaded portion and the second threaded portion, respectively. The second ends 212b of the two support members 212 abut against the pressing plate 22, and the sides of the two support members 212 facing away from each other abut against the two push blocks 214. Wherein, as... Figures 4 to 5 The state change of the drive assembly 21 shown is such that when the two push blocks 214 move toward each other, the two push blocks 214 can drive the two support members 212 to rotate toward each other about their respective first ends 212a, so that the second ends 212b of the two support members 212 together push against the extrusion plate 22 in the direction from the back 102 to the face 101; as Figures 5 to 4 The state change of the drive assembly 21 shown is such that when the two push blocks 214 move away from each other, the two support members 212 can rotate away from each other about their respective first ends 212a, so that the second ends 212b of the two support members 212 release the pushing action on the extrusion plate 22 in the direction from the face 101 to the back 102.

[0056] Through the above settings, firstly, the drive assembly 21 can support the extrusion plate 22 together with two support members 212, so that there are two support positions between the drive assembly 21 and the extrusion plate 22. The drive assembly 21 can provide relatively stable support for the extrusion plate 22 through these two support positions, optimizing the force structure between the drive assembly 21 and the extrusion plate 22 and avoiding the situation of force concentration between the drive assembly 21 and the extrusion plate 22 due to a single support position. Secondly, each support member 212 can simultaneously obtain support at the rotational connection between its first end 212a and the mounting base 211 and at the abutment point between the support member 212 and the push block 214, optimizing the force structure of the support member 212 and avoiding the situation of localized force concentration on the support member 212, which could easily lead to structural damage to the support member 212. This allows the support member 212 to support the extrusion plate 22 more stably.

[0057] In practice, the mounting base 211 can be installed on the frame of the seat 100 so that the drive assembly 21 is integrally connected to the frame of the seat 100, thereby providing a stable mounting position for the drive assembly 21. It is understood that the mounting base 211 can also be a part of the frame of the seat 100, that is, the drive rod 213 and the push block 214 are directly connected to the frame of the seat 100.

[0058] like Figure 4 and Figure 5As shown, in some embodiments, the support member 212 extends in an arc shape along the direction from the first end 212a to the second end 212b, and the center of the arc is located on the side of the support member 212 away from the push block 214 it abuts against. Thus, compared to a straight support member 212, when the push block 214 moves the same distance along the axial direction of the drive rod 213, the second end 212b of the arc-shaped support member 212 can generate a larger displacement in the thickness direction H of the pad 10, and push the extrusion plate 22 to generate a larger amplitude of movement to extrude force to the pad 10, so that the pad 10 can generate a larger amount of compression in its thickness direction H, thereby enabling the extrusion mechanism 20 to provide a larger hardness adjustment range and achieve a better hardness adjustment effect.

[0059] In some other embodiments, the support member 212 may extend in other forms along the direction from the first end 212a to the second end 212b. For example, the support member 212 may extend straight along the direction from the first end 212a to the second end 212b.

[0060] like Figure 2 and Figure 3 As shown, in some embodiments, the push block 214 defines a limiting groove 2131, and the support member 212 is limited to the limiting groove 2131. The limiting groove 2131 is used to restrict the support member 212 from moving relative to the push block 214 along the axial direction of the rotational connection of the first end 212a. In this way, the support member 212 can be stably abutted against the push block 214, and the support member 212 is prevented from shifting along the axial direction of the rotational connection of the first end 212a during the movement of the push block 214 against the support member 212. This helps to ensure that the support member 212 rotates smoothly around the first end 212a and pushes against the extrusion plate 22.

[0061] like Figure 3 As shown, in some embodiments, each support member 212 includes a rotating shaft 2121 and a support portion 2122. The rotating shaft 2121 is rotatably connected to the mounting base 211, and the support portion 2122 is connected to the rotating shaft 2121. The end of the support portion 2122 away from the rotating shaft 2121 abuts against the pressing plate 22, and the sides of the support portions 2122 of the two support members 212 that are away from each other abut against two push blocks 214 respectively.

[0062] Optionally, the axis of the rotating shaft 2121 is perpendicular to the axis of the drive rod 213, and the axis of the drive rod 213 is parallel to the width direction W of the cushion 10. Here, the width direction W of the cushion 10 refers to the direction in which the cushion 10 is parallel to the width of the human body when an occupant is sitting on it.

[0063] like Figure 2 and Figure 3As shown, in some embodiments, the support portion 2122 is U-shaped, with the open end of the U-shaped tube being one end of the support portion 2122 connected to the rotating shaft 2121, and the arc end of the U-shaped tube being the other end of the support portion 2122 away from the rotating shaft 2121.

[0064] In some other embodiments, the support portion 2122 may also have other structural shapes, such as a straight plate or an arc-shaped plate.

[0065] In some other embodiments, the drive rod 213 may also be an electric actuator, the output end of which is connected to the push block 214. The axial direction of the electric actuator is perpendicular to the axial direction of the rotatable connection at the first end 212a of the support member 212.

[0066] In other embodiments, the mounting base 211, support member 212, push block 214 and pressing plate 22 may also be connected in other ways. For example, the first ends 212a of the two support members 212 are rotatably connected to the two push blocks 214 respectively, and the second ends 212b of the two support members 212 are rotatably connected to the pressing plate 22 respectively. When the drive rod 213 drives the two push blocks 214 to move toward or away from each other, the two push blocks 214 can force the two support members 212 to rotate respectively, so that the second ends 212b of the two support members 212 jointly push the pressing plate 22 in the direction from the back 102 to the face 101, or jointly release the pushing action on the pressing plate 22 in the direction from the face 101 to the back 102.

[0067] like Figure 2 and Figure 3 As shown, in some embodiments, the mounting base 211 includes a base body 2111 and two supports 2112. The two supports 2112 are respectively connected to the base body 2111.

[0068] The drive rod 213 is rotatably connected to the base 2111. The drive rod 213 can rotate clockwise or counterclockwise relative to the base 2111 about its own axis, so that the two push blocks 214 move toward or away from each other. The drive rod 213 is rotatably mounted on the base 2111 via bearings.

[0069] The base 2111 is defined with a guide groove 2113, and two push blocks 214 are respectively guided and engaged with the guide groove 2113. The guide groove 2113 is used to guide the push blocks 214 to move axially along the drive rod 213. The two opposite inner sidewalls of the guide groove 2113 along the radial direction of the drive rod 213 can restrict the rotation of the push blocks 214 relative to the base 2111, so that when the drive rod 213 rotates, it can drive the push blocks 214 to move axially along the drive rod 213. The two opposite inner sidewalls of the guide groove 2113 along the axial direction of the drive rod 213 can limit the stroke of the push blocks 214 along the axial direction of the drive rod 213, so as to prevent the push blocks 214 from disengaging from the drive rod 213.

[0070] Two supports 2112 are located on opposite sides of the drive rod 213 in the radial direction. Each support 2112 defines two rotating holes 2114. One rotating hole 2114 in each of the two supports 2112 is a pair and coaxially arranged. The other rotating hole 2114 in each of the two supports 2112 is another pair and coaxially arranged. The two ends of the rotating shaft 2121 of one support member 212 pass through a pair of rotating holes 2114, and the two ends of the rotating shaft 2121 of the other support member 212 pass through another pair of rotating holes 2114, so that each support member 212 can rotate around the rotating shaft 2121.

[0071] like Figure 2 As shown, in some embodiments, the drive assembly 21 further includes a drive source 215 connected to the drive rod 213. The drive source 215 is used to drive the drive rod 213 to rotate about its own axis, so that the two push blocks 214 move toward or away from each other along the axial direction of the drive rod 213.

[0072] In some embodiments, the drive source 215 is a motor, and the output end of the motor is connected to the drive rod 213.

[0073] In some other embodiments, the drive source 215 may also be other structures used to drive the drive rod 213 to rotate about its own axis. For example, the drive source 215 may be a knob connected to the drive rod 213. By rotating the knob, the drive rod 213 can be rotated about its own axis.

[0074] In some other embodiments, the drive assembly 21 may also be other structures that can be used to drive the extrusion plate 22 to extrude the pad 10, such as an electric push rod whose output end is connected to the extrusion plate 22. The output end of the electric push rod can push against the extrusion plate 22 or release the pushing action on the extrusion plate 22.

[0075] Understandably, when an occupant sits on the seat 100, different parts of the body perceive the firmness of the cushion 10 differently. For example, when a person sits on the cushion 10 on the base of the seat 100, most of the body's weight is applied to the cushion 10 through the buttocks. When a person leans against the cushion 10 on the back of the seat 100, the body applies more pressure to the cushion 10 through the upper back. In other words, the buttocks and upper back of the person perceive the firmness of the cushion 10 more clearly.

[0076] Therefore, as Figure 6 and Figure 7 As shown, in some embodiments, the seat 100 further includes a frame, a base, and a backrest. The base and backrest are respectively disposed on the frame; the base is provided with a cushion 10, a compression mechanism 20, and a tensioning member 30. The third end 22a of the compression plate 22 is rotatably connected to the frame, and the fourth end 22b of the compression plate 22 is connected to the drive assembly 21. The third end 22a of the compression plate 22 is correspondingly disposed at a position of the cushion 10 away from the backrest, and the fourth end 22b of the compression plate 22 is correspondingly disposed at a position of the cushion 10 near the backrest; and / or, the backrest is provided with a cushion 10, a compression mechanism 20, and a tensioning member 30. The third end 22a of the compression plate 22 is rotatably connected to the frame, and the fourth end 22b of the compression plate 22 is connected to the drive assembly 21. The third end is correspondingly disposed at a position of the cushion 10 near the base, and the fourth end 22b is correspondingly disposed at a position of the cushion 10 away from the base.

[0077] When the drive assembly 21 drives the compression plate 22 to rotate around the third end 22a, the range of motion of each position on the compression plate 22 in the thickness direction H of the cushion 10 gradually increases along the direction from the third end 22a to the fourth end 22b. The amount of compression generated by the compression plate 22 on the corresponding area of ​​the cushion 10 also gradually increases. Specifically, the fourth end 22b of the compression plate 22 can generate a larger range of motion in the thickness direction H of the cushion 10 and compress the cushion 10, resulting in a larger amount of compression in the area corresponding to the buttocks or upper back of the human body. Conversely, the third end 22a of the compression plate 22 can generate a smaller range of motion in the thickness direction H of the cushion 10 and compress the cushion 10, resulting in a smaller amount of compression in the area corresponding to the legs or lower back of the human body. This allows the compression mechanism 20 to adjust the hardness of the corresponding area of ​​the cushion 10 to different degrees according to the different perceived levels of firmness by the human body. Thus, the seat 100 has a better firmness adjustment effect, resulting in a better experience for the occupant.

[0078] In some embodiments, the frame includes a mounting bracket 40 disposed on the side of the back 102 opposite to the face 101, and the third end 22a of the extrusion plate 22 is rotatably connected to the frame.

[0079] In some embodiments, the mounting base 211 is connected to the mounting bracket 40.

[0080] like Figure 1 As shown, in some embodiments, the face 101 is connected to the tensioning member 30 on both sides along the width direction W of the cushion 10. Thus, when the squeezing mechanism 20 forces the face 101 to move or deform in the direction from the back 102 toward the face 101, the tensioning member 30 can pull the face 101 from both sides, so that both sides of the face 101 can be tightened at the same time.

[0081] In some embodiments, the seat 100 further includes a frame, which includes a tensioning member 50. The tensioning member 50 is disposed on the side of the backrest 102 opposite to the face 101. The tensioning member 30 is a flexible member, which includes a first segment 31, a second segment 32, and a third segment 33. The first segment 31, the second segment 32, and the third segment 33 are connected in sequence. The second segment 32 is wrapped around the tensioning member 50. The first segment 31 and the third segment 33 are respectively disposed on both sides of the width direction W of the cushion 10, and both the first segment 31 and the third segment 33 are connected to the face 101. With the above arrangement, a single flexible member can simultaneously pull the face 101 on both sides of the width direction W of the cushion 10. The second segment 32 of the flexible member is wrapped around the tensioning member 50, so that the first segment 31 and the third segment 33 can apply the same pulling force to the face 101, which helps to balance the force on both sides of the face 101 and avoids uneven deformation on both sides of the face 101 due to uneven force.

[0082] In some embodiments, the flexible member of the cushion 10 connected to the base is disposed near the backrest of the cushion 10; the flexible member of the cushion 10 connected to the backrest is disposed away from the base of the cushion 10. With these arrangements, combined with the greater compression generated by the area of ​​the cushion 10 corresponding to the buttocks or upper back of the human body, the flexible member can further tighten the area of ​​the cushion 10 corresponding to the buttocks or upper back of the human body, making the area of ​​the cushion 10 corresponding to the buttocks or upper back of the human body more compact.

[0083] In some embodiments, the flexible element may be a rope, wire, cloth strip, etc.

[0084] like Figure 1 As shown, in some embodiments, there are two tensioning members 50, which are spaced apart along the width direction W of the pad 10. The two ends of the second segment 32 of the flexible member are respectively wrapped around the two tensioning members 50, so that the flexible member is roughly U-shaped.

[0085] In some embodiments, the tensioning member 50 is rotatably connected to the mounting bracket 40, and the tensioning member 50 can rotate relative to the mounting bracket 40 about its own axis, thereby reducing the friction between the tensioning member 50 and the flexible member.

[0086] In some embodiments, the tensioning member 50 may be omitted, and the tensioning member 30 may be a skin on one side of the pad 10 in the width direction. The skin is connected to the face 101 and the back 102. When the squeezing mechanism 20 forces the face 101 to make a certain movement or deformation in the direction from the back 102 to the face 101, the skin can pull the face 101 in the direction from the face 101 to the back 102, so that the face 101 is tightened.

[0087] In some other embodiments, the tensioning member 30 may also be a rigid member, such as a connecting plate (or connecting rod), one end of which is connected to the face 101 and the other end of which is connected to the mounting bracket 40.

[0088] In the first state (initial state), such as Figure 4 As shown, the distance between the two push blocks 214 is relatively large and they are far apart from each other. The second end 212a of each support member 212 abuts against the corresponding push block 214 and is close to the mounting base 211, and the included angle between the two support members 212 is relatively large. At this time, as shown... Figure 6 As shown, the angle between the extrusion plate 22 and the mounting bracket 40 is small, and the distance between the fourth end 22b of the extrusion plate 22 and the mounting base 211 is small and close to the mounting base 211, so the flexible part is in a state of just tension or relaxation; Figure 5 As shown, in the second state (compression state), the distance between the two push blocks 214 is small and they are close to each other. The first end 212a of each support member 212 abuts against the corresponding push block 214, and the second end 212a of each support member 212 is far away from the mounting base 211. The included angle between the two support members 212 is small. At this time, as... Figure 7 As shown, the angle between the extrusion plate 22 and the mounting bracket 40 is large, and the distance between the fourth end 22b of the extrusion plate 22 and the mounting base 211 is large and far away from the mounting base 211, so the flexible part is in a taut state.

[0089] The working principle of the seat 100 according to an embodiment of the present invention will be described by way of example below:

[0090] When it is necessary to increase the hardness of the cushion 10, the drive rod 213 can be driven to rotate forward by the motor, so that the two push blocks 214 move toward each other along the axial direction of the drive rod 213. The two push blocks 214 push against the two support members 212 respectively, so that the two support members 212 gradually rotate toward each other around their respective first ends 212a, thereby causing the second ends 212b of the two support members 212 to gradually move away from the mounting base 211 and push against the extrusion plate 22 to gradually rotate around the third end 22a of the extrusion plate 22, thereby causing the fourth end 22b of the extrusion plate 22 to gradually rotate. The cushion 10 is compressed away from the mounting base 211 and in the direction from the back 102 to the face 101. At the same time, the compression action of the compression plate 22 will force the face 101 to move or deform in the direction from the back 102 to the face 101. The first segment 31 and the third segment 33 of the flexible part can pull the face 101 in the direction from the face 101 to the back 102, so that the face 101 of the cushion 10 is tightened. In the above process, the cushion 10 gradually undergoes compression deformation and gradually becomes harder, eventually increasing the hardness of the cushion 10.

[0091] When it is necessary to reduce the hardness of the pad 10, the drive rod 213 can be reversed by the motor, so that the two push blocks 214 move away from each other along the axial direction of the drive rod 213. The two push blocks 214 release the pushing force of the two support members 212, so that the two support members 212 can gradually rotate away from each other around their respective first ends 212a, thereby causing the second ends 212b of the two support members 212 to gradually approach the mounting base 211 and release the pushing force on the pressing plate 22. The pressing plate 22, under its own weight and the pad 10, can then release the pushing force of the pressing plate 22. Under the elastic force of 0, the third end 22a of the extrusion plate 22 gradually rotates, thereby causing the fourth end 22b of the extrusion plate 22 to gradually move closer to the mounting base 211 and release the extrusion force on the soft pad 10 in the direction from the face 101 to the back 102. At the same time, the face 101 of the soft pad 10 gradually resets and gradually removes the force on the flexible part, so that the flexible part can gradually return to a state of just tension or relaxation. In the above process, the soft pad 10 gradually recovers its deformation and gradually changes from hard to soft, ultimately reducing the hardness of the soft pad 10.
