The component 14 is annular, and the transmission component 14 is wound around the driving wheel 122 and the driven wheel 132. The driving wheel 122 meshes with the transmission component 14, and the driven wheel 132 meshes with the transmission component 14. The driving wheel 122 drives the corresponding driven wheel 132 to rotate through the transmission component 14, so that the driven wheel 132 can move relative to the connecting member 131 along the axial direction of the connecting member 131. One of the driven wheel 132 and the connecting member 131 moves relative to the bracket 11 along the axial direction of the connecting member 131.

[0040] It should be noted that during the movement of one of the driven wheel 132 and the connecting member 131 relative to the bracket 11 along the axial direction of the connecting member 131, the driving wheel 122 and the driven wheel 132 move together, and the relative positions of the driving wheel 122 and the driven wheel 132 remain unchanged.

[0041] It should be noted that the axial direction of the driving wheel 122 is parallel to the axial direction of the driven wheel 132.

[0042] For example, the axis of the drive wheel 122 is parallel to the axis of the connector 131.

[0043] For example, the driven wheel 132 is disposed on the bracket 11, and the connector 131 moves relative to the bracket 11 along the axial direction of the connector 131.

[0044] For example, the connector 131 is disposed on the bracket 11, and the driven wheel 132 moves relative to the bracket 11 along the axial direction of the connector 131.

[0045] For example, the bracket 11 is disposed in the seat bucket.

[0046] For example, the seat cushion 2 is disposed on the driven wheel 132 or the connector 131 so that at least a portion of the seat cushion 2 moves up and down relative to the bracket 11 along the axial direction of the connector 131.

[0047] For example, a first seat 21 is disposed on a driven wheel 132 or a connector 131, and the first seat 21 moves up and down relative to the bracket 11 along the axial direction of the connector 131.

[0048] For example, the driving wheel 122 drives the driven wheel 132 to rotate in two opposite directions.

[0053] For example, the axis of the drive wheel 122 is parallel to the vertical direction.

[0054] For example, the driving wheel 122 can drive the driven wheel 132 to rotate in two opposite directions.

[0055] For example, the axial direction of the connector 131 is as shown by arrow R1 in the figure.

[0056] For example, the radial direction of the drive wheel 122 is as shown by arrow R2 in the figure.

[0057] In this embodiment, the transmission member 14 is wound around the driving wheel 122 and the driven wheel 132. The driving wheel 122 meshes with the transmission member 14, and the driven wheel 132 meshes with the transmission member 14. There is essentially no relative sliding between the transmission member 14 and the driving wheel 122, and between the transmission member 14 and the driven wheel 132, which allows for more precise control of the transmission ratio and improves transmission efficiency. The driving wheel 122 drives the corresponding driven wheel 132 to rotate through the transmission member 14, so that the driven wheel 132 can move relative to the connecting member 131 along the axial direction of the connecting member 131. One of the driven wheel 132 and the connecting member 131 moves relative to the bracket 11 along the axial direction of the connecting member 131. Power is transmitted to the lifting mechanism 13 through the driving wheel 122 and the transmission member 14, causing the lifting mechanism 13 to drive the seat cushion 2 to rise and fall, thereby allowing the height of the seat to be adjusted according to the user's needs and improving riding comfort.

[0058] In some embodiments, please refer to Figures 1-7 The transmission component 14 is a synchronous belt.

[0059] It should be noted that the drive pulley 122 is a pulley that is matched with the timing belt.

[0060] It should be noted that the driven pulley 132 is a pulley that is matched with the timing belt.

[0061] In this embodiment, the transmission component 14 is a synchronous belt. The driving pulley 122 meshes with the synchronous belt, and the driven pulley 132 meshes with the synchronous belt. The rotation of the driving pulley 122 drives the synchronous belt to move, and the synchronous belt drives the driven pulley 132 to rotate. The transmission structure is relatively simple.

[0062] It is understood that the transmission element 14 is not limited to a synchronous belt. Exemplarily, the transmission element 14 is a transmission chain.

[0063] In some embodiments, please refer to Figures 1-7 The number of lifting mechanisms 13 is at least two, and each lifting mechanism 13 is provided with a drive wheel 122 and a transmission component 14. The at least two lifting mechanisms 13 are arranged at radial intervals along the drive wheel 122.

[0064] For example, each lifting mechanism 13 is provided with a corresponding bracket 11.

[0065] For example, the number of lifting mechanisms 13 is two, three, or four.

[0066] For example, the number of lifting mechanisms 13 of the short-tail seat cushion 2 is two.

[0067] For example, the short-tailed seat cushion 2 is a single seat cushion 2.

[0068] For example, the number of lifting mechanisms 13 of the long-tail cushion 2 is two.

[0069] For example, the long-tailed seat cushion 2 is a multi-person seat cushion 2.

[0070] For example, the seat cushion 2 is provided on at least two lifting mechanisms 13.

[0071] In this embodiment of the application, there are at least two lifting mechanisms 13. Each lifting mechanism 13 is provided with a drive wheel 122 and a transmission component 14. The at least two lifting mechanisms 13 are arranged radially at intervals along the drive wheel 122. The at least two lifting mechanisms 13 can support the seat cushion 2 from at least two positions to drive the seat cushion 2 to rise and fall, which is convenient for driving the larger seat cushion 2 to rise and fall, and increasing the applicability of the adjustment device 1.

[0072] It is understood that the number of lifting mechanisms 13 is not limited to at least two. For example, the number of lifting mechanisms 13 is one.

[0073] For example, the number of lifting mechanisms 13 is one suitable for short-tailed seat cushions 2.

[0074] In some embodiments, please refer to Figure 2 , Figure 3 and Figure 7 The drive mechanism 12 includes a mounting shaft 121 and at least two drive wheels 122. The at least two drive wheels 122 are spaced apart along the axial direction of the mounting shaft 121. The at least two drive wheels 122 are connected to the mounting shaft 121 to rotate with the mounting shaft 121. The drive wheels 122 have a first mounting groove 1221 for mounting the transmission component 14, and the driven wheels 132 have a second mounting groove 1321 for mounting the transmission component 14. The first mounting groove 1221 of the drive wheel 122 and the second mounting groove 1321 of the corresponding driven wheel 132 have the same central surface.

[0075] It should be noted that at least two drive wheels 122 are connected to the same mounting shaft 121.

[0076] It should be noted that the center surface of the first mounting groove 1221 of the drive wheel 122 is the center surface of one side of the groove wall of the first mounting groove 1221 along the radial direction of the drive wheel 122, and the center surface of the first mounting groove 1221 is perpendicular to the axial direction of the drive wheel 122.

[0077] For example, the center surface of the first mounting slot 1221 is horizontal.

[0078] It should be noted that the center surface of the second mounting groove 1321 of the driven wheel 132 is the center surface of one side of the groove wall of the second mounting groove 1321 along the radial direction of the driven wheel 132. The center surface of the second mounting groove 1321 is perpendicular to the axial direction of the driving wheel 122.

[0079] For example, the center surface of the second mounting slot 1321 is horizontal.

[0080] It should be noted that the first mounting groove 1221 and the corresponding second mounting groove 1321 having a common center plane means that the center plane of the first mounting groove 1221 is parallel to or coincides with the center plane of the second mounting groove 1321. When the center plane of the first mounting groove 1221 is parallel to the center plane of the second mounting groove 1321, the distance between the center planes of the first mounting groove 1221 and the center planes of the second mounting groove 1321 along the axial direction of the drive wheel 122 is small, for example, less than or equal to 1 mm.

[0081] For example, the center surface of the first mounting groove 1221 coincides with the center surface of the corresponding second mounting groove 1321.

[0082] It should be noted that the first mounting groove 1221 and the corresponding second mounting groove 1321 having a common center plane means that the first mounting groove 1221 and the second mounting groove 1321 where the same transmission component 14 is located have a common center plane.

[0083] In this embodiment, at least two drive wheels 122 are spaced apart along the axial direction of the mounting shaft 121. The at least two drive wheels 122 are connected to the mounting shaft 121 to rotate with the mounting shaft 121. The mounting shaft 121 can drive the at least two drive wheels 122 to rotate together, thereby driving the at least two lifting mechanisms 13 to rise and fall. This is beneficial to improve the synchronicity of the movement of the at least two lifting mechanisms 13, can reduce the number of driving force sources, and simplify the structure of the adjustment device 1.

[0084] It is understood that at least two drive wheels 122 are not limited to being connected to the mounting shaft 121 to rotate with the mounting shaft 121. Exemplarily, at least two drive wheels 122 rotate independently.

[0085] In some embodiments, please refer to Figures 1-7 The adjustment device 1 includes a mounting frame 17, a mounting shaft 121 passing through the mounting frame 17, and a mounting body 171 located between two adjacent drive wheels 122 along the axial direction of the mounting shaft 121. The mounting body 171 is used to mount the seat cushion 2, and the lifting mechanism 13 is used to drive at least part of the seat cushion 2 to rise or fall.

[0086] For example, the lifting mechanism 13 is used to drive the first seat plate 21 of the seat cushion 2 to rise and fall.

[0087] For example, the driven wheel 132 moves axially relative to the bracket 11 along the connector 131, the mounting body 171 is connected to the first seat plate 21, the first seat plate 21 drives the mounting body 171 to rise and fall together, and the mounting shaft 121 and the drive wheel 122 follow the mounting body 171 to rise and fall together.

[0088] For example, the second seat 22 is connected to the bracket 11, and the first seat 21 is raised and lowered relative to the second seat 22.

[0089] For example, the connector 131 moves relative to the bracket 11 along the axial direction of the connector 131, the driven wheel 132 remains in a constant position relative to the bracket 11 along the axial direction of the connector 131, the mounting body 171 is connected to the second seat plate 22, and during the lifting and lowering of the first seat plate 21, the mounting body 171 remains in a constant position relative to the second seat plate 22 along the axial direction of the drive wheel 122, and the mounting shaft 121 and the drive wheel 122 remain in a constant position relative to the second seat plate 22 along the axial direction of the drive wheel 122.

[0090] For example, the mounting bracket 17 is connected to the mounting shaft 121.

[0091] For example, the mounting bracket 17 abuts against the drive wheel 122 on opposite sides along the axial direction of the drive wheel 122.

[0092] In this embodiment, the mounting shaft 121 passes through the mounting frame 17. The mounting frame 17 includes a mounting body 171 located between two adjacent drive wheels 122 along the axial direction of the mounting shaft 121. The mounting body 171 is used to mount the seat cushion 2. The lifting mechanism 13 is used to drive at least part of the seat cushion 2 to rise and fall. The mounting shaft 121 is set on the seat cushion 2 through the mounting body 171. The mounting body 171 can limit the mounting shaft 121, reduce the shaking of the mounting shaft 121 and the drive wheel 122 during the lifting and falling process, and make the drive wheel 122 move together with the driven wheel 132.

[0093] In some embodiments, please refer to Figures 2-4The adjusting device 1 also includes a coupling 15, and the driving mechanism 12 includes a driving device 123 for providing power. The output shaft 1231 of the driving device 123 is coaxially arranged with the mounting shaft 121. The coupling 15 connects the mounting shaft 121 and the output shaft 1231 of the driving device 123 so that the driving device 123 drives the mounting shaft 121 to rotate.

[0094] For example, the mounting bracket 17 includes a mounting member 172, which is connected to the first seat plate 21, and the drive device 123 is mounted on the mounting member 172.

[0095] For example, the mounting member 172 is at least partially located on one side of one drive wheel 122 away from the other drive wheel 122 along the axial direction of the drive wheel 122.

[0096] For example, the mounting body 171 is connected to the mounting component 172.

[0097] In this embodiment, the drive mechanism 12 includes a drive device 123 for providing power. The output shaft 1231 of the drive device 123 is coaxially arranged with the mounting shaft 121. A coupling 15 connects the mounting shaft 121 and the output shaft 1231 of the drive device 123 so that the drive device 123 drives the mounting shaft 121 to rotate. The drive device 123 can drive the mounting shaft 121 to rotate through the coupling 15 without changing the structure of the mounting shaft 121 or the output shaft 1231 of the drive device 123. The structures of the mounting shaft 121 and the output shaft 1231 of the drive device 123 can be set to be relatively simple.

[0098] It is understood that the installation is not limited to coupling 15. Exemplarily, mounting shaft 121 has a mounting cavity in which the output shaft 1231 of drive device 123 is located, and the cavity wall restricts the output shaft 1231 from rotating relative to mounting shaft 121 in the circumferential direction of output shaft 1231.

[0099] In some embodiments, please refer to Figures 2-4 The coupling 15 includes a sleeve 151 and at least two abutting members 152. The sleeve 151 is sleeved on the mounting shaft 121 and the output shaft 1231. The sleeve 151 has at least two through holes 1511 spaced apart along the axial direction of the mounting shaft 121. The through holes 1511 penetrate the side wall of the sleeve 151 radially along the mounting shaft 121. The abutting members 152 are respectively located in the corresponding through holes 1511. One abutting member 152 abuts against the mounting shaft 121 radially along the mounting shaft 121, and the other abutting member 152 abuts against the output shaft 1231 radially along the mounting shaft 121.

[0100] For example, sleeve 151 is integrally formed with one of the drive wheels 122.

[0101] For example, the surface of the mounting shaft 121 that contacts the abutment 152 is a plane.

[0102] In this embodiment, one abutment 152 abuts against the mounting shaft 121 radially, and the other abutment 152 abuts against the output shaft 1231 radially. The friction between the abutment 152 and the mounting shaft 121 restricts the movement of the mounting shaft 121 relative to the sleeve 151, and the friction between the abutment 152 and the output shaft 1231 restricts the movement of the output shaft 1231 relative to the sleeve 151, so that the power of the output shaft 1231 is transmitted to the mounting shaft 121. The coupling 15 has a simple structure.

[0103] In some embodiments, please refer to Figures 5-7 The drive mechanism 12 includes an operating device 124, which is connected to the drive wheel 122 so that the drive wheel 122 rotates following the operating device 124.

[0104] It should be noted that the operating device 124 itself does not provide power; the operating device 124 requires external force to drive it.

[0105] For example, the operating device 124 is operated by hand or tool.

[0106] For example, the operating device 124 is located on the underside of all the drive wheels 122.

[0107] For example, the operating device 124 is located on the lower side of the first seat plate 21.

[0108] For example, the operating device 124 is located on the side of the second seat 22 opposite to the first seat 21.

[0109] In this embodiment, the operating device 124 is connected to the drive wheel 122 so that the drive wheel 122 rotates with the operating device 124. The operation device 124 drives the drive wheel 122 to rotate, facilitating operation and reducing interference to the transmission mechanism caused by directly operating the drive wheel 122. This also helps the adjusting device 1 adjust the seat height. Since the operating device 124 itself does not provide power, it can be operated by a person, allowing for seat cushion 2 adjustment even when the vehicle is without power.

[0110] In some embodiments, please refer to Figures 5-7 The drive mechanism 12 includes a drive unit 123 for providing power, which drives the drive wheel 122 to rotate.

[0111] It should be noted that the connection between the drive unit 123 and the drive wheel 122 includes both direct and indirect connections.

[0112] For example, the drive unit 123 is indirectly connected to the drive wheel 122 via the mounting shaft 121.

[0113] For example, the drive wheel 122 has a mounting hole, and the output shaft 1231 of the drive device 123 is located in the mounting hole of the drive wheel 122.

[0114] For example, the drive device 123 includes a driver and a reducer, with the reducer disposed at the output end of the driver and the drive wheel 122 disposed at the output end of the reducer.

[0115] For example, the driver is a motor.

[0116] In this embodiment, the drive device 123 is used to drive the drive wheel 122 to rotate. The drive device 123 provides power to drive the drive wheel 122 to rotate, thereby realizing the lifting mechanism 13 to lift. No manual operation is required, which improves the automation level of the adjustment device 1.

[0117] In some embodiments, please refer to Figures 1-7 The adjusting device 1 includes a lifting member 16, which is disposed on the driven wheel 132. The connecting member 131 is connected to the bracket 11. The driven wheel 132 moves relative to the bracket 11 along the axial direction of the connecting member 131, thereby driving the lifting member 16 to move relative to the bracket 11 along the axial direction of the connecting member 131.

[0118] For example, at least a portion of the seat cushion 2 is connected to the lifting member 16.

[0119] For example, the first seat 21 is connected to the lifting member 16.

[0120] For example, bracket 11 is bolted to connector 131.

[0121] For example, the axial direction of the connector 131 is parallel to the vertical direction.

[0122] In this embodiment, the lifting member 16 is disposed on the driven wheel 132, and the connecting member 131 is connected to the bracket 11. The driven wheel 132 moves relative to the bracket 11 along the axial direction of the connecting member 131, thereby driving the lifting member 16 to move relative to the bracket 11 along the axial direction of the connecting member 131. The driven wheel 132 rotates and moves relative to the bracket 11, while the connecting member 131 can remain stationary relative to the bracket 11. The bracket 11 does not need to have a limiting structure to limit the driven wheel 132 and the connecting member 131, simplifying the structure of the adjustment device 1. By providing the lifting member 16, the movement of the driven wheel 132 drives the lifting member 16 to rise and fall, thereby achieving seat height adjustment. This allows the driven wheel 132 to avoid direct contact with the seat cushion 2; the seat cushion 2 only needs to be connected to the lifting member 16. The structural modifications to the seat cushion 2 itself are minimal, facilitating compatibility with various vehicles.

[0123] It is understood that the lifting member 16 is not limited to being disposed on the driven wheel 132, nor is it limited to being connected to the bracket 11 via the connecting member 131. Exemplarily, the driven wheel 132 is disposed on the bracket 11, the bracket 11 restricts the driven wheel 132 from moving axially along the connecting member 131, the bracket 11 restricts the connecting member 131 from rotating, causing the connecting member 131 to move relative to the bracket 11 along its axial direction, and the lifting member 16 is disposed on the connecting member 131.

[0124] It is understood that the adjustment device 1 is not limited to the installation of the lifting member 16. For example, the driven wheel 132 is sleeved on the connecting member 131, the seat cushion 2 is sleeved on the connecting member 131, and the seat cushion 2 is located above the driven wheel 132.

[0125] In some embodiments, please refer to Figures 1-7 The driven wheel 132 is threadedly connected to the connecting member 131. The driven wheel 132 can move along the axial direction of the connecting member 131 to drive the lifting member 16 to move relative to the bracket 11 along the axial direction of the connecting member 131.

[0126] For example, the driven wheel 132 is fitted onto the connector 131.

[0127] For example, the connector 131 is a screw.

[0128] For example, the adjustment device 1 includes a limiting member disposed on the side of the connector 131 away from the bracket 11 along the axial direction of the connector 131, so as to restrict the movement of the driven wheel 132 away from the bracket 11 along the axial direction of the connector 131.

[0129] For example, the limiting element is a retaining ring.

[0130] For example, the limiting member is a nut that is threadedly connected to the connector 131.

[0131] In this embodiment, the driven wheel 132 is threadedly connected to the connecting member 131. The driven wheel 132 can move along the axial direction of the connecting member 131 to drive the lifting member 16 to move relative to the bracket 11 along the axial direction of the connecting member 131. When the driving wheel 122 drives the driven wheel 132 to rotate relative to the connecting member 131, the driven wheel 132 moves along the axial direction of the connecting member 131. The lifting member 16 moves along the axial direction of the connecting member 131 through threaded transmission. The threaded connection between the driven wheel 132 and the connecting member 131 eliminates the need for a lifting cylinder or hydraulic cylinder in the adjusting device 1. Mechanical transmission is less expensive than hydraulic transmission, thus reducing the production cost of the adjusting device 1.

[0132] It is understood that the driven wheel 132 is not limited to being threadedly connected to the connector 131. Exemplarily, the connector 131 has meshing teeth, the driven wheel 132 has meshing teeth, and the driven wheel 132 meshes with the connector 131.

[0133] In some embodiments, please refer to Figures 1-7 The drive mechanism 12 includes at least two drive wheels 122, and driven wheels 132 are correspondingly arranged with the drive wheels 122. The at least two driven wheels 132 are located on opposite sides of the drive wheels 122 along the radial direction of the drive wheels 122. The driven wheel 132 located on one side of the radial direction of the drive wheels 122 is higher than the driven wheel 132 located on the other side of the radial direction of the drive wheels 122. The seat cushion 2 includes a first seat plate 21, and the drive mechanism 12 passes through the first seat plate 21. The at least two drive wheels 122 are located on opposite sides of the first seat plate 21 along the axial direction of the drive wheels 122.

[0134] For example, at least two driven wheels are located on opposite sides of the driving wheel 122 in the front-rear direction.

[0135] For example, the seat cushion 2 also includes a sponge and a cover, which are disposed on the first seat plate 21.

[0136] For example, the sponge and skin are at least partially disposed above the first seat 21.

[0137] In this embodiment, at least two driven wheels 132 are located on opposite sides of the driving wheel 122 along its radial direction. One driven wheel 132 on one side of the radial direction of the driving wheel 122 is higher than the other driven wheel 132 on the other side, creating a height difference in the seat cushion 2 along the radial direction of the driving wheel 122, thus improving the comfort of the seat cushion 2. The height difference between the driven wheels 132 on opposite sides of the radial direction of the driving wheel 122 also creates a height difference in the axial direction of the driving wheel 122. These at least two driven wheels 122 are located on opposite sides of the first seat plate 21 along the axial direction of the driving wheel 122. By utilizing the space within the first seat plate 21 along the axial direction of the driving wheel 122, the space occupied by the driven wheels 122 along the axial direction of the driving wheel 122 is reduced, thus reducing the size of the seat cushion 2.

[0138] It is understood that at least two drive wheels 122 are not necessarily located on opposite sides of the first seat plate 21 along the axial direction of the drive wheels 122. Exemplarily, all drive wheels 122 are located on the underside of the first seat plate 21.

[0139] In some embodiments, please refer to Figures 1-4 The drive mechanism 12 includes a drive unit 123 for providing power, which drives the drive wheel 122 to rotate. The drive unit 123 is located below the drive wheel 122.

[0140] It should be noted that the drive unit 123 is located below all the drive wheels 122.

[0141] In this embodiment, the drive device 123 is used to drive the drive wheel 122 to rotate. The drive device 123 is located below the drive wheel 122. The drive device 123 can be set in the space below the first seat plate 21, which reduces the space occupied by the drive device 123 along the axial direction of the drive wheel 122 in the seat cushion 2, and helps to reduce the size of the seat cushion 2 along the axial direction of the drive wheel 122.

[0142] It is understood that the drive unit 123 is not limited to being located below the drive wheel 122.

[0143] For example, the drive unit 123 is located above the drive wheel 122.

[0144] For example, the adjustment device 1 includes a steering gear, and the drive device 123 is located on one side of the drive wheel 122 along the radial direction of the drive wheel 122. The drive device 123 drives the drive wheel 122 to rotate through the steering gear.

[0145] In some embodiments, the support 11 is disposed on the seat bucket, and the driven wheel 132 or the connector 131 is connected to the seat cushion 2 so that at least a portion of the seat cushion 2 moves up and down relative to the support 11 along the axial direction of the connector 131.

[0146] It should be noted that the connection between the driven wheel 132 and the seat cushion 2 means that the driven wheel 132 drives the seat cushion 2 to rise and fall, not that the driven wheel 132 and the seat cushion 2 are fixedly connected. The driven wheel 132 can rotate relative to the seat cushion 2.

[0147] For example, the driven wheel 132 is sleeved on the connector 131, the connector 131 is connected to the bracket, the driven wheel 132 moves up and down relative to the bracket 11 along the axial direction of the connector, the driven wheel 132 is supported under the first seat plate 21, and the driven wheel 132 drives the first seat plate 21 of the seat cushion 2 to move up and down.

[0148] For example, the first seat plate 21 of the seat cushion 2 is bolted to the lifting member 16.

[0149] For example, the lifting member 16 is sleeved on the connecting member 131, and the driven wheel 132 is supported below the lifting member 16. The driven wheel 132 drives the lifting member 16 and the first seat plate 21 to rise and fall together.

[0150] It should be noted that the connection between connector 131 and seat cushion 2 means that connector 131 drives seat cushion 2 to rise and fall, and connector 131 can be indirectly connected to seat cushion 2.

[0151] For example, when the driven wheel 132 rotates, the bracket 11 restricts the driven wheel 132 from moving up and down along the axial direction of the connector 131, so that the connector 131 moves up and down along the axial direction of the connector 131. The connector 131 is threadedly connected to the lifting member 16, and the connector 131 drives the lifting member 16 to move up and down together with the first seat plate 21.

[0152] In some embodiments, the second seat 22 is connected to the bracket 11.

[0153] For example, sponge and skin cover the first seat 21 and the second seat 22.

[0154] For example, the grip is located on the side of the second seat 22 opposite to the first seat 21.

[0155] It should be noted that the second seat 22 does not rise or fall with the first seat 21.

[0156] In some embodiments, the number of supports 11 is at least one, and at least one support 11 includes a first sub-frame 111, the first sub-frame 111 being rotatably connected to the seat bucket, the seat bucket having a support portion, and when the seat cushion 2 is in the closed state, the upper side of the support portion abuts against the first sub-frame 111.

[0157] It should be noted that when there is only one support 11, the support 11 is the first sub-support 111. When there are at least two supports 11, at least one of the supports 11 is the first sub-support 111.

[0158] In some embodiments, please refer to Figures 1-7 The number of supports 11 is at least two, and the at least two supports 11 include a second sub-frame 112. The second sub-frame 112 is connected to the seat bucket buckle. When the seat cushion 2 is in the closed state, the locking hook 113 is locked with the buckle to restrict the movement of the second sub-frame 112. When the seat cushion 2 is in the open state, the locking hook 113 is disengaged from the buckle.

[0159] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. 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.
