[0030] In related technologies, a bicycle seat includes an adjustment device, a seat cushion, and a seat bucket. The seat bucket has a receiving cavity. The adjustment device is used to adjust the height of the seat cushion. The adjustment device includes a bracket, at least two lifting mechanisms, a drive wheel, and a transmission component. The lifting mechanism includes a driven wheel. The transmission component is arranged around the drive wheel and at least two driven wheels. The drive wheel drives the driven wheels to rotate through the transmission component, so that at least a part of the lifting mechanism rises or falls relative to the bracket. The transmission component is relatively close to the driven wheels in the lateral direction. The transmission component occupies a large amount of space between two adjacent driven wheels in the front-rear direction. The transmission component may interfere with objects in the receiving cavity, resulting in inconvenience in using the bicycle seat.

[0031] It should be noted that the space between two adjacent driven wheels in the front-to-back direction refers to the space enclosed by the outer common tangent of the projection areas of two adjacent drive wheels in the up-down direction.

[0032] For example, when the object inside the cavity is a helmet, the top of the helmet is arc-shaped, the middle area of ​​the top of the helmet protrudes, the transmission component is located between two adjacent driven wheels, and the transmission component may interfere with the top of the helmet.

[0033] This application provides a vehicle, which includes a vehicle body and a seat, with the seat disposed on the vehicle body.

[0034] For example, the vehicle is a two-wheeled vehicle.

[0035] For example, the vehicle is an electric vehicle.

[0036] For example, the vehicle is a two-wheeled electric vehicle.

[0037] For example, the vehicle is a motorcycle.

[0038] This application provides a vehicle seat, which includes a seat bucket 3, an adjustment device 1, and a seat cushion 2. The seat bucket 3 has a receiving cavity 31.

[0039] For example, the receiving cavity 31 is used for storage.

[0040] For example, the receiving cavity 31 is used to store the helmet.

[0041] For example, the cushion 2 includes a first seat plate 21, and the adjustment device 1 is capable of raising and lowering the first seat plate 21.

[0042] This application provides an adjustment device 1, please refer to... Figures 1-5The adjusting device 1 includes a bracket 11, at least two lifting mechanisms 13, a drive wheel 12, a transmission component 14, and a tensioning wheel 15. Each lifting mechanism 13 includes a driven wheel 131. At least two lifting mechanisms 13 are arranged at intervals along a longitudinal direction R2, which intersects with a vertical direction R1. The plane coinciding with the rotation center axis 1311 of the driven wheels of the at least two lifting mechanisms 13 is a preset plane 1312. The drive wheel 12 is located between two adjacent driven wheels 131 along the longitudinal direction R2, and the rotation center axis 121 of the drive wheel intersects with the preset plane 1312 along a transverse direction R3. Planes 1312 are arranged at intervals, with the transverse direction R3 intersecting the front-to-back direction R2 and the vertical direction R1 respectively; the transmission member 14 is ring-shaped and is wound around the driving wheel 12 and at least two driven wheels 131. The driving wheel 12 drives the driven wheels 131 to rotate through the transmission member 14, so that at least a part of the lifting mechanism 13 rises or falls relative to the support 11; the rotation center axis of the tensioning wheel 15 is spaced apart from the preset plane 1312 along the transverse direction R3, and the transmission member 14 is wound around at least one side of the tensioning wheel 15 away from the preset plane 1312 along the transverse direction R3.

[0043] It should be noted that the intersection of the front-back direction R2 and the up-down direction R1 means that the front-back direction R2 and the up-down direction R1 are not parallel.

[0044] It should be noted that when the horizontal R3 intersects the front-back direction R2 and the vertical direction R1 respectively, it means that the horizontal R3 is not parallel to the front-back direction R2 and the horizontal R3 is not parallel to the vertical direction R1.

[0045] For example, the axial direction of the driving wheel 12 is parallel to the axial direction of the driven wheel 131.

[0046] For example, the axial direction of the drive wheel 12 is parallel to the vertical direction R1.

[0047] For example, the bracket 11 is disposed on the seat 3.

[0048] For example, the first seat plate 21 is mounted on the lifting mechanism 13 so that the lifting mechanism 13 drives the first seat plate 21 to rise and fall relative to the bracket 11.

[0049] For example, the vertical direction R1 is perpendicular to the front-back direction R2.

[0050] For example, the vertical direction R1 is perpendicular to the horizontal direction R3.

[0051] For example, the front-to-back direction R2 is perpendicular to the lateral direction R3.

[0052] For example, when a user is driving the vehicle, the lateral direction R3 is parallel to the user's left and right directions.

[0053] For example, the transmission element 14 is positioned horizontally.

[0054] In this embodiment, the transmission member 14 is arranged around the driving wheel 12 and the driven wheel 131. The driving wheel 12 drives the corresponding driven wheel 131 to rotate through the transmission member 14, so that at least part of the lifting mechanism 13 rises or falls relative to the bracket 11. The lifting mechanism 13 drives at least part of the seat cushion 2 to rise and fall, thereby enabling the height of the seat to be adjusted according to the user's needs and improving driving comfort. The driving wheel 12 is located between two adjacent driven wheels 131 along the front-rear direction R2. The rotation center axis 121 of the driving wheel is spaced apart from the preset plane 1312 along the transverse direction R3. The rotation center axis of the tension wheel 15 is spaced apart from the preset plane 1312 along the transverse direction R3. The transmission component 14 is at least wrapped around the side of the tension wheel 15 that is away from the preset plane 1312 along the transverse direction R3. By changing the position of the transmission component 14 through the tension wheel 15, the transmission component 14 is moved away from the preset plane 1312 along the transverse direction R3, reducing the space occupied by the transmission component 14 between two adjacent driven wheels 131 along the front-rear direction R2, reducing the possibility of interference between the transmission component 14 and the objects in the receiving cavity 31, and making the seat convenient to use.

[0055] In some embodiments, please refer to Figures 1-5 The tensioning wheel 15 is spaced apart from the driven wheel 131 along the transverse direction R3.

[0056] It should be noted that the interval between the tensioning wheel 15 and the driven wheel 131 along the transverse direction R3 refers to the interval between the projection areas of the tensioning wheel 15 and the driven wheel 131 when projected along the front-rear direction R2.

[0057] For example, the tensioning wheel 15 is located near the edge of the first seat plate 21.

[0058] For example, a portion of the transmission element 14 between the tensioner 15 and the tensioner 15 is located near the edge of the first seat plate 21.

[0059] In this embodiment, the tensioning wheel 15 is spaced apart from the driven wheel 131 along the transverse direction R3, further moving the transmission component 14 away from the driven wheel 131 along the transverse direction R3, reducing the space occupied by the transmission component 14 between two adjacent driven wheels 131, reducing the possibility of interference between the transmission component 14 and the object in the receiving cavity 31, and making the seat convenient to use.

[0060] It is understood that the tensioning wheel 15 is not limited to being spaced apart from the driven wheel 131 along the transverse direction R3. Exemplarily, when projected along the front-rear direction R2, the projection area of ​​the tensioning wheel 15 partially overlaps with the projection area of ​​the driven wheel 131.

[0061] In some embodiments, please refer to Figures 1-5 The driving wheel 12 is spaced apart from the driven wheel 131 along the transverse direction R3.

[0062] It should be noted that the distance between the driving wheel 12 and the driven wheel 131 along the transverse direction R3 refers to the distance between the projection area of ​​the driving wheel 12 and the projection area of ​​the driven wheel 131 when projected along the longitudinal direction R2.

[0063] For example, the drive wheel 12 is located near the edge of the first seat plate 21.

[0064] For example, a portion of the transmission element 14 between the tension wheel 15 and the drive wheel 12 is located near the edge of the first seat plate 21.

[0065] For example, the tensioning wheel 15, the driving wheel 12, and the driven wheel 131 are located on the same side of the first seat plate 21 and close to the edge of the first seat plate 21. This brings the transmission member 14 closer to the edge of the first seat plate 21, reducing the space occupied by the transmission member 14 in the middle of the first seat plate 21.

[0066] In this embodiment, the driving wheel 12 is spaced apart from the driven wheel 131 along the transverse direction R3, and the transmission component 14 is further moved away from the driven wheel 131 along the transverse direction R3, reducing the space occupied by the transmission component 14 between two adjacent driven wheels 131, reducing the possibility of interference between the transmission component 14 and the object in the receiving cavity 31, and making the seat convenient to use.

[0067] It is understood that the driving wheel 12 is not limited to being spaced apart from the driven wheel 131 along the transverse direction R3. For example, when projected along the front-rear direction R2, the projection area of ​​the driving wheel 12 partially overlaps with the projection area of ​​the driven wheel 131.

[0068] In some embodiments, please refer to Figures 1-5 The tension wheel 15 and the drive wheel 12 are located on the same side of the preset plane 1312 along the transverse direction R3.

[0069] In this embodiment, the tensioning wheel 15 and the driving wheel 12 are located on the same side of the preset plane 1312 along the transverse R3. The tensioning wheel 15 and the driving wheel 12 are arranged using the space on one side of the preset plane 1312 along the transverse R3. The space on the other side of the preset plane 1312 along the transverse R3 will not be occupied by the tensioning wheel 15, reducing the space occupied by the transmission component 14 on the other side of the preset plane 1312 along the transverse R3. The space on the other side of the preset plane 1312 along the transverse R3 can be used flexibly as needed.

[0070] It is understood that the tensioning pulley 15 is not limited to being located on the same side of the preset plane 1312 along the transverse direction R3 as the driving pulley 12. Exemplarily, the tensioning pulley 15 and the driving pulley 12 are located on opposite sides of the preset plane 1312 along the transverse direction R3.

[0071] In some embodiments, please refer to Figures 1-5The number of tensioning pulleys 15 is at least three, at least one of which is the first pulley 151, and the other tensioning pulleys 15 are the second pulleys 152. The first pulley 151 is located within the area enclosed by the transmission member 14, and the second pulley 152 is located outside the area enclosed by the transmission member 14.

[0072] For example, there are three tensioning pulleys 15, one first pulley 151, and two second pulleys 152.

[0073] For example, the minimum distance between the first wheel 151 and the driven wheel 131 along the front-rear direction R2 is less than the minimum distance between the first wheel 151 and the driving wheel 12 along the front-rear direction R2.

[0074] For example, the minimum distance between the driving wheel 12 and the driven wheel 131 in the front-rear direction R2 is less than the minimum distance between the first wheel 151 and the driving wheel 12 in the front-rear direction R2.

[0075] In this embodiment, at least one tensioning wheel 15 is a first wheel 151, and the other tensioning wheels 15 besides the first wheel 151 are second wheels 152. The first wheel 151 is located within the area enclosed by the transmission member 14, and the second wheel 152 is located outside the area enclosed by the transmission member 14. This makes the portion of the transmission member 14 between the driving wheel 12 and the first wheel 151 spaced apart from the preset plane 1312 along the lateral direction R3, and makes the portion of the transmission member 14 between at least two second wheels 152 spaced apart from the preset plane 1312, thereby reducing the space occupied by the transmission member 14 between the driven wheels 131.

[0076] It is understood that the number of tensioner pulleys 15 is not limited to at least three. For example, the number of tensioner pulleys 15 is one.

[0077] It is understood that the first wheel 151 is not limited to being located within the area enclosed by the transmission member 14; for example, the first wheel 151 is located outside the area enclosed by the transmission member 14.

[0078] In some embodiments, the first wheel 151 engages with the transmission member 14.

[0079] For example, the transmission component 14 is a synchronous belt, and the first pulley 151 is a synchronous pulley that cooperates with the synchronous belt.

[0080] In this embodiment, the first wheel 151 engages with the transmission component 14, reducing the possibility of the transmission component 14 slipping during transmission.

[0081] It is understood that the first wheel 151 is not limited to engaging with the transmission member 14. Exemplarily, the first wheel 151 is in surface contact with the transmission member 14.

[0082] In some embodiments, the driving wheel 12 engages with the transmission member 14, and the driven wheel 131 engages with the transmission member 14.

[0083] For example, the transmission component 14 is a synchronous belt.

[0084] For example, the transmission component 14 is a perforated belt.

[0085] For example, the transmission element 14 is a perforated cloth belt.

[0086] For example, the transmission component 14 is a chain.

[0087] In this embodiment, the driving wheel 12 meshes with the transmission component 14, and the driven wheel 131 meshes with the transmission component 14. There is basically no relative sliding between the transmission component 14 and the driving wheel 12, and between the transmission component 14 and the driven wheel 131, which can control the transmission ratio more accurately and improve the transmission efficiency.

[0088] It is understood that the driving wheel 12 is not limited to meshing with the transmission member 14, and the driven wheel 131 is not limited to meshing with the transmission member 14. Exemplarily, the driving wheel 12 contacts the transmission member 14 by frictional transmission, and the driven wheel 131 contacts the transmission member 14 by frictional transmission.

[0089] In some embodiments, please refer to Figures 1-5 The adjusting device 1 includes an operating device 17, which is connected to the drive wheel 12 so that the drive wheel 12 rotates following the operating device 17.

[0090] It should be noted that the operating device 17 itself does not provide power; the operating device 17 requires external force to drive it.

[0091] For example, the operating device 17 is operated by hand or tool.

[0092] For example, the operating device 17 is located on the underside of all the drive wheels 12.

[0093] For example, the operating device 17 is located on the lower side of the first seat plate 21.

[0094] In this embodiment, the operating device 17 is connected to the drive wheel 12 so that the drive wheel 12 rotates with the operating device 17. The operation device 17 drives the drive wheel 12 to rotate, which facilitates operation and reduces interference to the transmission component 14 caused by directly operating the drive wheel 12. This is also beneficial for the adjustment device 1 to adjust the height of the seat. Since the operating device 17 itself does not provide power, it can be operated by an operator. Even if the vehicle is without power, the seat cushion 2 can still be raised and lowered.

[0095] In some embodiments, the adjusting device 1 includes a driving device for providing power to drive the drive wheel 12 to rotate.

[0096] It should be noted that the connection between the drive unit and the drive wheel 12 includes both direct and indirect connections.

[0097] For example, the drive unit is indirectly connected to the drive wheel 12 via a mounting shaft.

[0098] For example, the drive wheel 12 has a mounting hole, and the output shaft of the drive device is located in the mounting hole of the drive wheel 12.

[0099] For example, the driving device includes a driver and a reducer, with the reducer disposed at the output end of the driver and the drive wheel 12 disposed at the output end of the reducer.

[0100] For example, the driver is a motor.

[0101] In this embodiment, the drive device is used to provide power to drive the drive wheel 12 to rotate. By providing power to drive the drive wheel 12 to rotate, the lifting mechanism 13 can be raised and lowered without manual operation, thus improving the automation level of the adjustment device 1.

[0102] In some embodiments, please refer to Figures 1-5 The lifting mechanism 13 also includes a connecting member 132, which is correspondingly provided with the driven wheel 131. At least two connecting members 132 are respectively connected to the bracket 11. The driven wheel 131 is sleeved on the corresponding connecting member 132. The driven wheel 131 is threadedly connected to the connecting member 132. The driven wheel 131 can move up and down relative to the bracket 11 along the axial direction of the connecting member 132.

[0103] For example, the number of brackets 11 is at least two, and a connector 132 is connected to one bracket 11.

[0104] In this embodiment, the driven wheel 131 is sleeved on the corresponding connecting member 132. The driven wheel 131 and the connecting member 132 are threadedly connected. The driven wheel 131 can move up and down relative to the bracket 11 along the axial direction of the connecting member 132. The transmission member 14 drives the driven wheel 131 to rotate relative to the connecting member 132. The connecting member 132 is connected to the bracket 11. The driven wheel 131 and the connecting member 132 are threadedly connected. During rotation, the driven wheel 131 moves up and down along the axial direction of the connecting member 132, thereby driving at least part of the seat cushion 2 to move up and down. The driven wheel 131 and the connecting member 132 are threadedly connected. When the driven wheel 131 stops rotating, the relative position of the driven wheel 131 and the connecting member 132 can remain unchanged, and the adjustment device 1 may not have a self-locking structure.

[0105] It is understood that the driven wheel 131 is not limited to being threadedly connected to the connector 132. Exemplarily, the driven wheel 131 engages with the connector 132.

[0106] It is understood that the connector 132 is not limited to being connected to the bracket 11, nor is it limited to the driven wheel 131 moving up and down relative to the bracket 11 along the axial direction of the connector 132. Exemplarily, the connector 132 moves up and down relative to the bracket 11 along the axial direction of the connector 132.

[0107] In some embodiments, please refer to Figures 1-5 The drive wheel 12 is rotatably connected to the first seat plate 21, and the tension wheel 15 is rotatably connected to the first seat plate 21.

[0108] For example, the driven wheel 131 is capable of moving up and down relative to the bracket 11 along the axial direction of the connector 132.

[0109] In this embodiment, the drive wheel 12 is rotatably connected to the first seat plate 21, and the tension wheel 15 is rotatably connected to the first seat plate 21. The drive wheel 12 and the tension wheel 15 can rise and fall together with the first seat plate 21. During the rising and falling of the first seat plate 21, the distance between the drive wheel 12 and the driven wheel 131 remains unchanged, and the distance between the tension wheel 15 and the driven wheel 131 remains unchanged, so the transmission is relatively stable.

[0110] It is understood that the drive wheel 12 is not limited to being rotatably connected to the first seat plate 21. For example, the seat cushion 2 includes a second seat plate, the first seat plate 21 is raised and lowered relative to the second seat plate, and the drive wheel 12 is actively connected to the second seat plate.

[0111] It is understood that the tension wheel 15 is not limited to being rotatably connected to the first seat plate 21. Exemplarily, the seat cushion 2 includes a second seat plate, the first seat plate 21 being raised and lowered relative to the second seat plate, and the tension wheel 15 being rotatably connected to the second seat plate.

[0112] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 5 The drive wheel 12 is rotatably connected to the first seat plate 21. The seat also includes a mounting assembly 4. At least one tension wheel 15 is rotatably connected to the mounting assembly 4. The mounting assembly 4 is at least partially movably disposed on the first seat plate 21 to change the relative position of at least one tension wheel 15 with respect to the drive wheel 12 along the lateral direction R3.

[0113] For example, of all tensioning rollers 15, one tensioning roller 15 is rotatably connected to the mounting assembly 4, and the remaining tensioning rollers 15, other than those rotatably connected to the mounting assembly 4, are rotatably connected to the first seat plate 21.

[0114] For example, one of the second wheels 152 is rotatably connected to the mounting component 4.

[0115] For example, the mounting assembly 4 is configured to correspond to the tensioning wheel 15, and all tensioning wheels 15 are rotatably connected to the mounting assembly 4.

[0116] For example, the mounting component 4 can be moved relative to the first seat plate 21, while the position of the mounting component 4 relative to the first seat plate 21 remains unchanged.

[0117] For example, all of the mounting components 4 are movable relative to the first seat plate 21.

[0118] In this embodiment, the mounting assembly 4 is at least partially movably disposed on the first seat plate 21 to change the relative position of at least one tensioning wheel 15 with the driving wheel 12 along the lateral direction R3. By moving the mounting assembly 4 relative to the first seat plate 21, the tension of the transmission component 14 is adjusted so that the pressure between the transmission component 14 and the driving wheel 12, the driven wheel 131 and the tensioning wheel 15 is within a suitable range, which facilitates the maintenance of the adjustment device 1, improves the service life of the adjustment device 1, and also facilitates the installation of the transmission component 14.

[0119] It is understood that, not limited to at least one tensioning wheel 15, it is rotatably connected to the mounting assembly 4. Exemplarily, all tensioning wheels 15 are rotatably connected to the first seat plate 21.

[0120] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 5 The mounting assembly 4 includes a locking member 43, a mounting member 41, and a movable member 42. The mounting member 41 is connected to the first seat plate 21, and the tension wheel 15 is rotatably connected to the movable member 42. The movable member 42 has a slide groove 421, and the extension direction of the slide groove 421 intersects the front-back direction R2 and the up-down direction R1, respectively. Part of the mounting member 41 is located in the slide groove 421. The locking member 43 is used to lock or unlock the movable member 42. When the movable member 42 is in the unlocked state, the mounting member 41 can move along the slide groove 421.

[0121] It should be noted that when the locking member 43 is in the locked state, the movable member 42 is relatively fixed to the mounting member 41, and the movable member 42 cannot move relative to the mounting member 41.

[0122] For example, the groove 421 passes through the movable member 42 in the vertical direction R1.

[0123] For example, the groove 421 is an oblong hole, and the long side of the oblong hole is parallel to the extending direction of the groove 421.

[0124] For example, the mounting member 41 has a flange, and the flange and the locking member 43 are located on opposite sides of the movable member 42 in the vertical direction R1. When the locking member 43 is locked, the locking member 43 presses the movable member 42 against the flange to restrict the movement of the movable member 42 relative to the mounting member 41.

[0125] For example, the locking member 43 is threadedly connected to the mounting member 41.

[0126] In this embodiment, the locking member 43 is used to lock or unlock the movable member 42. When the movable member 42 is in the unlocked state, the mounting member 41 can move along the slide groove 421. Through the movable member 42 and the locking member 43, the position of the tension wheel 15 relative to the driving wheel 12 can be adjusted as needed, and the position of the tension wheel 15 relative to the driving wheel 12 can also be fixed, thereby adjusting the tightness of the transmission member 14.

[0127] It is understood that the mounting component 4 is not limited to including the locking member 43, the mounting member 41, and the movable member 42. For example, the first seat plate 21 is provided with at least two limiting holes, the arrangement direction of the at least two limiting holes intersects the front-back direction R2 and the up-down direction R1 respectively, and the mounting component 4 is located in one of the limiting holes.

[0128] In some embodiments, please refer to Figure 5 The projection area of ​​the driven wheel 131 along the vertical direction R1 is the first region 1313, and the projection area of ​​the first seat plate 21 along the vertical direction R1 is the second region 211. The second region 211 has a preset center line 212 extending along the front-rear direction R2. The first regions 1313 of at least two driven wheels 131 are straddling the opposite sides of the preset center line 212 along the transverse direction R3.

[0129] For example, the vehicle body is symmetrical about a preset centerline 212.

[0130] For example, the preset center line 212 is located on the preset plane 1312.

[0131] In this embodiment, the first region 1313 of at least two driven wheels 131 spans across the opposite sides of the preset center line 212 along the transverse R3. The load on the opposite sides of the first seat plate 21 along the transverse R3 can be transmitted to the driven wheels 131 more evenly, and then to the seat bucket 3 through the bracket 11. This improves the uniformity of the force on the first seat plate 21, reduces the deformation and bending of the first seat plate 21, and reduces the possibility of damage to the seat.

[0132] It is understood that the first region 1313 of at least two driven wheels 131 is not limited to spanning across opposite sides of the preset center line 212 along the transverse direction R3. Exemplarily, the first region 1313 of at least two driven wheels 131 is located on one side of the preset center line 212 along the transverse direction R3.

[0133] In some embodiments, please refer to Figure 5 The seat also includes a sensor 5, which is mounted on the first seat plate 21 and is located between two adjacent driven wheels 131 along the front-rear direction R2.

[0134] It should be noted that when sensor 5 is located between two adjacent driven wheels 131 along the front-back direction R2, it means that the projection area of ​​sensor 5 overlaps with the projection area of ​​the two adjacent driven wheels 131 when projected along the front-back direction R2.

[0135] For example, sensor 5 is used to detect the load on the first seat plate 21.

[0136] For example, sensor 5 is a pressure sensor.

[0137] For example, when the user is not sitting on the seat cushion 2, the sensor 5 senses that there is no load on the first seat plate 21 or that the load on the first seat plate 21 is very small, and the controller prevents the vehicle from starting. When the user is sitting on the seat cushion 2, the sensor 5 senses the load on the first seat plate 21 or senses that the load on the first seat plate 21 is large, and the vehicle controller enables the vehicle to start.

[0138] In this embodiment, sensor 5 is mounted on the first seat plate 21. Sensor 5 is located between two adjacent driven wheels 131 along the front-rear direction R2. Sensor 5 is positioned on the first seat plate 21 at a position away from the edge of the first seat plate 21 along the lateral direction R3, which can effectively detect the load on the first seat plate 21. The rotation center axis 121 of the driving wheel is spaced apart from the preset plane 1312 along the lateral direction R3, and the rotation center axis of the tensioning wheel 15 is also spaced apart from the preset plane 1312 along the lateral direction R3. This reduces the space occupied by the driving wheel 12 and the transmission component 14 between two adjacent driven wheels 131, ensuring sufficient space between two adjacent driven components for the sensor 5.

[0139] It is understood that the sensor 5 is not limited to being located between two adjacent driven wheels 131 along the front-to-back direction R2. Exemplarily, the sensor 5 is spaced apart from the preset plane 1312 along the lateral direction R3.

[0140] In some embodiments, the adjusting device 1 includes a lifting member 16, which is sleeved on the connecting member 132, and a driven wheel 131 is located below the lifting member 16 to support the lifting member 16.

[0141] For example, the first seat 21 is connected to the lifting member 16.

[0142] In some embodiments, the transmission member 14 and the tension wheel 15 are located within the space enclosed by the seat cushion 2 and the seat bucket 3.

[0143] In some embodiments, the adjustment device 1 is adapted to the short-tailed seat cushion 2.

[0144] For example, the short-tailed seat cushion is a single-person seat cushion.

[0145] In some embodiments, the adjustment device 1 is adapted to a long-tailed seat cushion.

[0146] For example, the long-tailed cushion is a multi-person cushion.

[0147] In some embodiments, the seat cushion 2 includes a cover 22 that covers the first seat 21.

[0148] For example, the covering 22 includes a sponge and a skin.

[0149] In some embodiments, each lifting mechanism 13 is provided with a corresponding support 11, and at least two supports 11 include a first sub-frame 111, which is rotatably connected to the seat 3.

[0150] In some embodiments, at least two supports 11 include a second sub-frame 112 having a locking hook 113 and a buckle 3 having a buckle. When the seat cushion 2 is in the closed state, the locking hook 113 engages with the buckle to support the second sub-frame 112. When the seat cushion 2 is in the open state, the locking hook 113 disengages from the buckle to allow the first sub-frame 111 to rotate relative to the seat cushion 3.

[0151] For example, the locking hook 113 is located on the underside of the second sub-frame 112.

[0152] For example, the second sub-frame 112 is located behind the first seat 21.

[0153] For example, the first sub-frame 111 is located in front of the first seat 21.

[0154] For example, the number of connectors 132 is at least two, and each connector 132 is connected to a corresponding bracket 11.

[0155] For example, at least one of the connectors 132 is connected to the second sub-frame 112.

[0156] For example, the upper part of the support abuts against the first sub-frame 111 to support the first sub-frame 111.

[0157] For example, the locking hook 113 is U-shaped.

[0158] For example, the latch has a locking groove. When the locking hook 113 is locked with the latch, the locking hook 113 is partially located in the locking groove, and the groove wall on the lower side of the locking groove abuts against the latch in the vertical direction R1.

[0159] For example, the latch is of type F.

Any modifications, equivalent substitutions, and improvements made within the spirit and scope of this application are included within the scope of protection of this application.
