[0034] For example, the vehicle is an electric vehicle.

[0035] For example, the vehicle is a two-wheeled vehicle.

[0036] For example, the vehicle is a motorcycle.

[0037] This application provides a vehicle seat, which includes a seat bucket, an adjustment device 1, and a seat cushion. The adjustment device 1 is disposed in the seat bucket, and the seat cushion is disposed in the adjustment device 1.

[0038] It should be noted that the adjustment device 1 is used to raise or lower at least a portion of the seat structure to adjust the height of the vehicle seat.

[0042] In this embodiment, the adjustment device 1 is disposed on the seat bucket, and the seat cushion is disposed on the adjustment device 1. The adjustment device 1 drives at least part of the seat cushion to rise and fall, thereby adjusting the height of the seat to meet the user's usage needs.

[0043] An adjusting device 1, please refer to Figures 1-7 The adjusting device 1 includes a bracket 11, a lifting mechanism 13, a driving mechanism 12, and a transmission mechanism 14. The lifting mechanism 13 includes a driven wheel 132 and a connecting member 131. The driven wheel 132 is disposed on the connecting member 131, and one of the driven wheel 132 and the connecting member 131 is disposed on the bracket 11. The driving mechanism 12 includes an operating device 121 and a driving wheel 122 connected to each other. The driving wheel 122 rotates with the operating device 121. One end of the transmission mechanism 14 is disposed on the driving wheel 122, and the other end of the transmission mechanism 14 is disposed on the driven wheel 132. The driving wheel 122 drives the driven wheel 132 to rotate through the transmission mechanism 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.

[0044] It should be noted that the operating device 121 itself does not provide power; the operating device 121 requires external force to drive it.

[0045] For example, the operating device 121 is operated by hand or tool.

[0046] 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.

[0047] 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.

[0048] For example, the bracket 11 is disposed in the seat bucket.

[0049] For example, the seat cushion is disposed on the driven wheel 132 or the connector 131 such that at least a portion of the seat cushion moves up and down relative to the bracket 11 along the axial direction of the connector 131.

[0050] For example, a first seat is disposed on the driven wheel 132 or the connector 131, and the first seat moves up and down relative to the bracket 11 along the axial direction of the connector 131.

[0051] For example, the driving wheel 122 drives the driven wheel 132 to rotate in two opposite directions.

[0052] For example, the transmission mechanism 14 is provided correspondingly to the bracket 11.

[0053] For example, the lifting mechanism 13 is provided correspondingly to the bracket 11.

[0054] For example, the number of supports 11 is at least one.

[0055] For example, the number of supports 11 is one, two, or three.

[0056] In this embodiment, the drive wheel 122 rotates following the operating device 121. One end of the transmission mechanism 14 is located on the drive wheel 122, and the other end is located on the driven wheel 132. The drive wheel 122 drives the driven wheel 132 to rotate through the transmission mechanism 14, allowing the driven wheel 132 to move relative to the connecting member 131 along its axial direction. One of the driven wheel 132 and the connecting member 131 moves relative to the bracket 11 along its axial direction. The drive wheel 122 drives the driven wheel 132 to rotate, causing either the driven wheel 132 or the connecting member 131 to move relative to the bracket 11 along its axial direction. Power is transmitted to the lifting mechanism 13 through the drive wheel 122 and the transmission mechanism 14, causing the lifting mechanism 13 to raise and lower the seat cushion, thereby adjusting the seat height and improving riding comfort. The operation device 121 drives the drive wheel 122 to rotate, facilitating operation and reducing interference with the transmission mechanism 14 caused by direct operation of the drive wheel 122. This also helps the adjusting device 1 adjust the seat height. Since the operating device 121 itself does not provide power, it can be operated by an operator, and the seat can still be raised and lowered even when the vehicle is without power.

[0057] In some embodiments, please refer to Figures 1-4 The drive wheel 122 has a mounting hole 1223. The operating device 121 includes an operating body 1211. Part of the operating body 1211 is located inside the mounting hole 1223, and part of the operating body 1211 is located outside the mounting hole 1223. The operating body 1211 abuts against the side wall of the mounting hole 1223 along the circumference of the drive wheel 122 to restrict the rotation of the drive wheel 122 relative to the operating body 1211.

[0058] For example, the mounting hole 1223 is a square hole.

[0059] For example, the mounting hole 1223 is a D-shaped hole or an elliptical hole.

[0060] For example, the operating body 1211 has a first part and a second part. The first part is located inside the mounting hole 1223, and the second part is located outside the mounting hole 1223. The first part abuts against the side wall of the mounting hole 1223 along the circumference of the drive wheel 122 and is projected along the axial direction of the drive wheel 122. The projection area of ​​the first part is located within the projection area of ​​the second part.

[0061] For example, the operating body 1211 is located on the side of the second seat plate opposite to the first seat plate along the axial direction of the drive wheel 122.

[0062] For example, the operating body 1211 passes through the opening of the second seat plate along the axial direction of the drive wheel 122; the second part is located on the side of the second seat plate opposite to the first seat plate along the axial direction of the drive wheel 122, and is projected along the axial direction of the drive wheel 122, with the projection area of ​​the opening of the second seat plate located within the projection area of ​​the second part.

[0063] In this embodiment, the operating body 1211 is partially located inside the mounting hole 1223 and partially located outside the mounting hole 1223. The operating body 1211 abuts against the side wall of the mounting hole 1223 along the circumference of the drive wheel 122 to restrict the rotation of the drive wheel 122 relative to the operating body 1211. The operating body 1211 drives the drive wheel 122 to rotate. The space inside the drive wheel 122 is used to set the operating body 1211, which reduces the interference of the operating body 1211 on the transmission mechanism 14 on the drive wheel 122.

[0064] It is understood that the operating body 1211 is not limited to abutting against the side wall of the mounting hole 1223 along the circumference of the drive wheel 122. Exemplarily, the operating body 1211 is connected to the drive wheel 122.

[0065] For example, the operating body 1211 is welded to the drive wheel 122.

[0066] For example, the operating body 1211 is key-connected to the drive wheel 122.

[0067] In some embodiments, please refer to Figures 1-4 The mounting hole 1223 is a through hole. The operating device 121 also includes a connecting shaft 1212. The connecting shaft 1212 is located on the side of the driving wheel 122 away from the operating body 1211 along the axial direction of the driving wheel 122. The connecting shaft 1212 is located inside the mounting hole 1223. The driving wheel 122 abuts against the operating body 1211 and the connecting shaft 1212 on opposite sides along the axial direction of the driving wheel 122.

[0068] For example, along the radial projection of the drive wheel 122, the projection area of ​​the portion of the connecting shaft 1212 located inside the mounting hole 1223 is located within the projection area of ​​the portion of the connecting shaft 1212 located outside the mounting hole 1223.

[0069] It should be noted that when one projection area is located within another projection area, it means that the boundaries of the two projection areas do not coincide.

[0070] For example, the drive wheel 122 abuts against the portion of the connecting shaft 1212 located within the mounting hole 1223 along the axial direction of the drive wheel 122.

[0071] For example, the connecting shaft 1212 portion is located within the operating body 1211.

[0072] For example, the connecting shaft 1212 and the operating body 1211 can rotate relative to each other.

[0073] For example, the connecting shaft 1212 is threadedly connected to the operating body 1211, and the connecting shaft 1212 can rotate with the operating body 1211.

[0074] In this embodiment, the connecting shaft 1212 is located on the side of the drive wheel 122 away from the operating body 1211 along the axial direction of the drive wheel 122. The connecting shaft 1212 is located inside the mounting hole 1223. The opposite sides of the drive wheel 122 along the axial direction of the drive wheel 122 abut against the operating body 1211 and the connecting shaft 1212, respectively. The connecting shaft 1212 and the operating body 1211 limit the drive wheel 122 along the axial direction of the drive wheel 122, reduce the shaking of the drive wheel 122 relative to the operating body 1211 along the axial direction of the drive wheel 122, and can better control the position of the drive wheel 122, thereby improving the structural stability of the adjustment device 1.

[0075] It is understood that the opposite sides of the drive wheel 122 along its axial direction are not limited to abutting against the operating body 1211 and the connecting shaft 1212 respectively. For example, the side of the drive wheel 122 away from the operating body 1211 along its axial direction is spaced apart from the connecting shaft 1212.

[0076] In some embodiments, please refer to Figures 1-4The mounting hole 1223 includes a first sub-hole 1224 and a second sub-hole 1225 that are connected. The first sub-hole 1224 and the second sub-hole 1225 are arranged along the axial direction of the drive wheel 122. The operating body 1211 is partially located in the first sub-hole 1224, and the connecting shaft 1212 is partially located in the second sub-hole 1225. The projection area of ​​the second sub-hole 1225 is located within the projection area of ​​the first sub-hole 1224 along the axial direction of the drive wheel 122. The hole wall of the first sub-hole 1224 on the side opposite to the operating body 1211 along the axial direction of the drive wheel 122 abuts against the operating body 1211.

[0077] It should be noted that the projection area of ​​the second sub-aperture 1225 is located within the projection area of ​​the first sub-aperture 1224, meaning that the boundary of the projection area of ​​the second sub-aperture 1225 does not coincide with the boundary of the projection area of ​​the first sub-aperture 1224.

[0078] For example, the drive wheel 122 is spaced apart from the operating body 1211 along the axial direction of the drive wheel 122 and away from the second sub-hole 1225.

[0079] For example, the seat cushion includes a second seat plate, a drive wheel 122 and an operating body 1211 located on opposite sides of the second seat plate along the axial direction of the drive wheel 122, with the operating body 1211 extending through the second seat plate.

[0080] In this embodiment, the projection area of ​​the second sub-hole 1225 along the axial projection of the drive wheel 122 is located within the projection area of ​​the first sub-hole 1224. The second sub-hole 1225 can be set to be smaller, reducing the impact of the opening on the structural strength of the drive wheel 122. The hole wall of the first sub-hole 1224 on the side away from the operating body 1211 along the axial direction of the drive wheel 122 abuts against the operating body 1211. The position where the operating body 1211 abuts against the drive wheel 122 is located inside the drive wheel 122, reducing the entry of water and dust into the gap between the operating body 1211 and the drive wheel 122, and reducing the impact of the external environment on the contact between the operating body 1211 and the drive wheel 122.

[0081] It is understood that, when projected along the axial direction of the drive wheel 122, the projection area of ​​the second sub-hole 1225 is not limited to the projection area of ​​the first sub-hole 1224. For example, when projected along the axial direction of the drive wheel 122, the projection area of ​​the second sub-hole 1225 coincides with the projection area of ​​the first sub-hole 1224.

[0082] It is understood that the hole wall of the first sub-hole 1224 abutting against the operating body 1211 on the side opposite to the operating body 1211 along the axial direction of the drive wheel 122 is not limited to this. For example, the drive wheel 122 abuts against the operating body 1211 on the side opposite to the second sub-hole 1225 along the axial direction of the drive wheel 122.

[0083] In some embodiments, please refer to Figures 1-4 The operating device 121 also includes a first mounting member 1213 and a second mounting member 1214 connected by threads. The first mounting member 1213 passes through the connecting shaft 1212 and the operating body 1211. The second mounting member 1214 is located on the side of the operating body 1211 opposite to the driving wheel 122 along the axial direction of the driving wheel 122. The second mounting member 1214 abuts against the operating body 1211 along the axial direction of the driving wheel 122. The first mounting member 1213 has a stop flange 1215 on the side of the first mounting member 1213 opposite to the operating body 1211 along the axial direction of the driving wheel 122. The connecting shaft 1212 is spaced apart from the stop flange 1215 on the side of the connecting shaft 1212 opposite to the operating body 1211 along the axial direction of the driving wheel 122, so as to install the seat cushion.

[0084] For example, the first mounting component 1213 is a screw.

[0085] For example, the second mounting part 1214 is a nut.

[0086] For example, the connecting shaft 1212 is spaced apart from the operating body 1211 on one side along the axial direction of the drive wheel 122 and from the stop flange 1215 for mounting the first seat plate, and the connecting shaft 1212 passes through the first seat plate.

[0087] For example, the drive wheel 122 is spaced apart from the operating body 1211 along the axial direction of the drive wheel 122 and the connecting shaft 1212 is spaced apart from the stop flange 1215 along the axial direction of the drive wheel 122.

[0088] In this embodiment, the second mounting member 1214 abuts against the operating body 1211 along the axial direction of the drive wheel 122, and the first mounting member 1213 is mounted on the operating body 1211. The first mounting member 1213 has a stop flange 1215 on the side opposite to the operating body 1211 along the axial direction of the drive wheel 122. The connecting shaft 1212 is spaced apart from the stop flange 1215 on the side opposite to the operating body 1211 along the axial direction of the drive wheel 122, so as to install the seat cushion. Through the first mounting member 1213, the second mounting member 1214 and the connecting shaft 1212, the drive wheel 122 and the operating body 1211 are mounted on the seat cushion, so that the drive wheel 122 and the operating body 1211 rise and fall together with the seat cushion. The drive wheel 122 can be kept away from the seat cushion, reducing the interference of the seat cushion with the rotation of the drive wheel 122.

[0089] It is understood that the first mounting member 1213 is not limited to penetrating the connecting shaft 1212 and the operating body 1211. Exemplarily, the connecting shaft 1212 penetrates the first seat plate, and the first mounting member 1213 is located on the side of the connecting shaft 1212 opposite to the operating body 1211 along the axial direction of the drive wheel 122. The first mounting member 1213 is threadedly connected to the connecting shaft 1212, and the connecting shaft 1212 is connected to the operating body 1211.

[0090] In some embodiments, please refer to Figures 1-4 The operating device 121 includes a grip 1216, which is disposed on the operating body 1211. The grip 1216 is at least partially located on the side of the operating body 1211 away from the driving wheel 122 along the axial direction of the driving wheel 122.

[0091] For example, the grip 1216 is located on the side of the operating body 1211 opposite to the drive wheel 122 along the axial direction of the drive wheel 122.

[0092] For example, all of the grips 1216 are located on the side of the operating body 1211 opposite to the drive wheel 122 along the axial direction of the drive wheel 122.

[0093] For example, the grip 1216 is located below the drive wheel 122.

[0094] For example, the grip 1216 is sleeved on the operating body 1211, and the second mounting member 1214 is located between the operating body 1211 and the grip 1216.

[0095] For example, the grip 1216 is a knob.

[0096] For example, the grip 1216 is a joystick.

[0097] For example, the grip 1216 is a shift fork mechanism, which drives the drive wheel 122 to rotate by shifting the lever of the shift fork mechanism.

[0098] For example, when projected along the axial direction of the drive wheel 122, the projection area of ​​the operating body 1211 is located within the projection area of ​​the grip 1216.

[0099] In this embodiment of the application, the operating device 121 includes a grip 1216, which is disposed on the operating body 1211. The grip 1216 is at least partially located on the side of the operating body 1211 away from the driving wheel 122 along the axial direction of the driving wheel 122, so as to facilitate gripping the grip 1216 from one side of the axial direction of the driving wheel 122, and to facilitate the use of the adjusting device 1.

[0100] It is understandable that the operating device 121 may not be equipped with a grip 1216.

[0101] In some embodiments, the grip 1216 is at least partially located on the side of the operating body 1211 opposite to the drive wheel 122 along the axial direction of the drive wheel 122.

[0102] For example, when the seat is closed, the grip 1216 is located below the operating body 1211.

[0103] In some embodiments, please refer to Figures 1-7The transmission mechanism 14 includes at least two cables, including a first cable 141 and a second cable 142. One end of the first cable 141 is wound around the driving wheel 122, and the other end of the first cable 141 is wound around the driven wheel 132 along a first direction of rotation. One end of the second cable 142 is wound around the driving wheel 122, and the other end of the second cable 142 is wound around the driven wheel 132 along a second direction of rotation. The first direction of rotation is opposite to the second direction of rotation. The first cable 141 is used to drive the driven wheel 132 to rotate along the first direction of rotation, and the second cable 142 is used to drive the driven wheel 132 to rotate along the second direction of rotation.

[0104] It should be noted that when the driving wheel 122 rotates in a preset direction, the first cable 141 wound around the driven wheel 132 along the first direction of rotation is released under the drive of the driving wheel 122, gradually detaching from the driven wheel 132, causing the driven wheel 132 to rotate in the first direction of rotation. The portion of the first cable 141 wound around the driving wheel 122 increases, and the second cable 142 wound around the driving wheel 122 is released. The second cable 142 then winds around the driven wheel 132 along the second direction of rotation, increasing the portion of the second cable 142 wound around the driven wheel 132. When the driving wheel 122 rotates in the opposite direction to the preset direction, the second cable 142 wound around the driven wheel 132 along the second direction of rotation is released under the drive of the driving wheel 122, gradually detaching from the driven wheel 132, causing the driven wheel 132 to rotate along the second direction of rotation, the portion of the second cable 142 wound around the driving wheel 122 increases, and the first cable 141 wound around the driving wheel 122 is released, the first cable 141 is wound around the driven wheel 132 along the second direction of rotation, and the portion of the first cable 141 wound around the driven wheel 132 increases.

[0105] It should be noted that "at least two cables including the first cable 141 and the second cable 142" means that among the at least two cables, at least one cable is the first cable 141 and at least the other cable is the second cable 142.

[0106] For example, the first direction of rotation is shown as arrow R1 in the figure, and the second direction of rotation is shown as arrow R2 in the figure.

[0107] For example, the transmission mechanism 14 includes two cables, one of which is a first cable 141 and the other is a second cable 142.

[0108] For example, the cable is a rope.

[0109] For example, the cable is a steel wire rope.

[0110] For example, the cable is a belt.

[0111] For example, the cable is a chain.

[0112] In this embodiment, one end of the first cable 141 is wound around the driving wheel 122, and the other end of the first cable 141 is wound around the driven wheel 132 along a first direction of rotation. One end of the second cable 142 is wound around the driving wheel 122, and the other end of the second cable 142 is wound around the driven wheel 132 along a second direction of rotation. The first direction of rotation and the second direction of rotation are opposite. The first cable 141 is used to drive the driven wheel 132 to rotate along the first direction of rotation, and the second cable 142 is used to drive the driven wheel 132 to rotate along the second direction of rotation. By the first cable 141 and the second cable 142 being wound around the driving wheel 122 and the driven wheel 132, the driving wheel 132 is rotated. The driven wheel 132 rotates in two opposite directions. The swaying and displacement of the driving wheel 122 and the driven wheel 132 will not cause the first cable 141 and the second cable 142 to jam. External impacts have little impact on the adjusting device 1. The adjusting device 1 has high structural reliability. The installation accuracy requirements of the first cable 141 with the driving wheel 122 and the driven wheel 132 are low. The installation accuracy requirements of the second cable 142 with the driving wheel 122 and the driven wheel 132 are also low. This makes it easier to manufacture and install the first cable 141, the second cable 142, the driving wheel 122 and the driven wheel 132, and can reduce the cost of the adjusting device 1.

[0113] It is understood that the transmission mechanism 14 is not limited to including at least two cables. Exemplarily, the transmission mechanism 14 includes a rack, the two ends of which mesh with a driving wheel 122 and a driven wheel 132, respectively.

[0114] In some embodiments, please refer to Figures 1-7 The outer side of the drive wheel 122 has at least two annular first mounting grooves 1221, and the at least two first mounting grooves 1221 are arranged at intervals along the axial direction of the drive wheel 122. A first cable 141 is partially located in one of the first mounting grooves 1221, and a second cable 142 is partially located in the other first mounting groove 1221.

[0115] For example, the number of first mounting slots 1221 is two, three, or four.

[0116] For example, there is one transmission mechanism 14 and two first mounting slots 1221.

[0117] For example, there are two transmission mechanisms 14 and four first mounting slots 1221.

[0118] In this embodiment, at least two first mounting slots 1221 are arranged axially at intervals along the drive wheel 122. A portion of the first cable 141 is located in one of the first mounting slots 1221, and a portion of the second cable 142 is located in the other first mounting slot 1221. The spaced first mounting slots 1221 on the drive wheel 122 can separate the first cable 141 and the second cable 142, reducing mutual interference between the first cable 141 and the second cable 142 on the drive wheel 122, facilitating the winding of the first cable 141 and the second cable 142 onto the drive wheel 122, and facilitating the transmission of the first cable 141 and the second cable 142.

[0119] It is understood that the drive wheel 122 is not limited to having at least two spaced first mounting slots 1221. For example, the number of first mounting slots 1221 is one, with the portion of the first cable 141 located in the first mounting slot 1221 and the portion of the second cable 142 located in the first mounting slot 1221 spaced apart.

[0120] In some embodiments, please refer to Figures 1-7 The driven wheel 132 has at least two annular second mounting grooves 1321 on its outer side. The at least two second mounting grooves 1321 are arranged at intervals along the axial direction of the driven wheel 132. The first cable 141 is partially located in one of the second mounting grooves 1321, and the second cable 142 is partially located in the other second mounting groove 1321.

[0121] For example, the number of second mounting slots 1321 is adapted to the number of cables of the corresponding transmission mechanism 14.

[0122] For example, there are two second mounting slots 1321.

[0123] In this embodiment, at least two second mounting slots 1321 are arranged axially spaced along the driven wheel 132. The first cable 141 is partially located in one of the second mounting slots 1321, and the second cable 142 is partially located in the other second mounting slot 1321. The spaced second mounting slots 1321 on the driven wheel 132 can separate the first cable 141 and the second cable 142, reducing mutual interference between the first cable 141 and the second cable 142 on the driven wheel 132, facilitating the winding of the first cable 141 and the second cable 142 onto the driven wheel 132, and facilitating the transmission of the first cable 141 and the second cable 142.

[0124] It is understood that the drive wheel 122 is not limited to having at least two spaced second mounting slots 1321. Exemplarily, the number of second mounting slots 1321 is one, with the portion of the second cable 142 located within the second mounting slot 1321 spaced apart from the portion of the second cable 142 located within the second mounting slot 1321.

[0125] 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.

[0126] For example, at least a portion of the seat cushion is connected to the lifting member 16.

[0127] For example, the first seat is connected to the lifting member 16.

[0128] For example, bracket 11 is bolted to connector 131.

[0129] 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; the seat cushion only needs to be connected to the lifting member 16. This requires minimal structural modification to the seat cushion itself, making it compatible with various vehicles.

[0130] 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.

[0131] 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 is sleeved on the connecting member 131, and the seat cushion is located above the driven wheel 132.

[0132] 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.

[0133] For example, the connector 131 is a screw, and the driven wheel 132 is sleeved on the screw.

[0134] 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.

[0135] 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.

[0136] In some embodiments, please refer to Figures 1-7 The adjusting device 1 includes a limiting member 133, which is disposed on the side of the connecting member 131 away from the bracket 11 along the axial direction of the connecting member 131, so as to restrict the movement of the driven wheel 132 away from the bracket 11 along the axial direction of the connecting member 131.

[0137] For example, the limiting member 133 is a retaining ring.

[0138] For example, the limiting member 133 is a nut that is threadedly connected to the connector 131.

[0139] In this embodiment, the limiting member 133 is 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. By limiting the movement of the driven wheel 132 through the limiting member 133, the possibility of the driven wheel 132 disengaging from the connector 131 is reduced, and the structural stability of the adjusting device 1 is improved.

[0140] It is understood that the adjustment device 1 is not limited to providing a limiting member 133. For example, the drive device does not provide a limiting member 133, and the drive device includes an encoder, which can control the movement stroke of the driven wheel 132 by controlling the power output of the drive device.

[0141] In some embodiments, please refer to Figures 1-7The driven wheel 132 has a transmission part 1323 and a mounting part 1324 arranged along the axial direction of the driven wheel 132. The transmission mechanism 14 is disposed in the transmission part 1323 and projected along the axial direction of the driven wheel 132. The projection area of ​​the mounting part 1324 is located within the projection area of ​​the transmission part 1323. The adjusting device 1 also includes a fastener 134 sleeved on the mounting part 1324. The fastener 134 is threadedly connected to the mounting part 1324. The lifting member 16 is sleeved on the mounting part 1324. The lifting member 16 is located between the fastener 134 and the transmission part 1323 along the axial direction of the driven wheel 132 to restrict the movement of the lifting member 16 relative to the driven wheel 132 along the axial direction of the driven wheel 132.

[0142] It should be noted that the projection area of ​​the mounting part 1324 being located within the projection area of ​​the transmission part 1323 means that the boundary of the projection area of ​​the mounting part 1324 does not coincide with the boundary of the projection area of ​​the transmission part 1323.

[0143] For example, a second mounting groove 1321 is formed in the mounting portion 1324.

[0144] For example, the second limiting groove 1322 is formed in the mounting portion 1324.

[0145] For example, the connector 131 is threadedly connected to the transmission part 1323.

[0146] In this embodiment, the projection area of ​​the mounting portion 1324 along the axial projection of the driven wheel 132 is located within the projection area of ​​the transmission portion 1323. The fastener 134 is threadedly connected to the mounting portion 1324. The lifting member 16 is sleeved on the mounting portion 1324. The lifting member 16 is located between the fastener 134 and the transmission portion 1323 along the axial projection of the driven wheel 132, thereby restricting the movement of the lifting member 16 relative to the driven wheel 132 along the axial projection of the driven wheel 132. By limiting the movement of the lifting member 16 relative to the driven wheel 132 through the fastener 134 and the transmission portion 1323, the lifting member 16 moves together with the driven wheel 132 as much as possible, reducing the jamming of the lifting member 16 during the lifting process and reducing the seat lifting caused by the shaking of the lifting member 16 due to external impact. This can better control the lifting of the seat and improve the reliability of the adjustment device 1.

[0147] It is understood that the adjusting device 1 is not limited to the fastener 134, and the driven wheel 132 is not limited to the transmission part 1323. 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. When the driven wheel 132 moves away from the lifting member 16 along the axial direction of the connecting member 131, the lifting member 16 descends under the action of gravity.

[0148] In some embodiments, please refer to Figures 1-7The adjusting device 1 also includes a bearing 135 and a mounting flange 136. The lifting member 16 is connected to the mounting flange 136. The bearing 135 is sleeved on the mounting part 1324, and the mounting flange 136 is sleeved on the bearing 135. The mounting flange 136 abuts against the bearing 135 on the side of the driven wheel 132 facing the transmission part 1323 along the axial direction of the driven wheel 132.

[0149] For example, the lifting component 16 is welded to the mounting flange 136.

[0150] For example, the mounting flange 136 is threaded to the bearing 135.

[0151] In this embodiment, the bearing 135 is sleeved on the mounting part 1324, and the mounting flange 136 is sleeved on the bearing 135. The mounting flange 136 abuts against the bearing 135 on the side of the driven wheel 132 facing the transmission part 1323 along the axial direction. There is relative rotation between the driven wheel 132 and the lifting member 16. The lifting member 16 and the driven wheel 132 are separated by the bearing 135 and the mounting flange 136, thereby reducing the contact wear between the driven wheel 132 and the lifting member 16.

[0152] It is understandable that the adjusting device 1 may not have a bearing 135 and a mounting flange 136.

[0153] In some embodiments, please refer to Figures 1-7 The mounting flange 136 abuts against the fastener 134 on the side opposite to the transmission part 1323 along the axial direction of the driven wheel 132.

[0154] For example, the adjusting device 1 includes a washer disposed between the fastener 134 and the bearing 135.

[0155] In this embodiment, the mounting flange 136 abuts against the fastener 134 on the side of the driven wheel 132 away from the transmission part 1323 along the axial direction. The fastener 134 presses the mounting flange 136 against the bearing 135 along the axial direction of the driven wheel 132. This reduces the shaking of the lifting component 16 caused by external impacts, lowers the risk of jamming during the lifting process, and improves the lifting stability. The lifting component 16 is relatively stationary with respect to the driven wheel 132, and the drive mechanism 12 does not drive the driven wheel 132 to rotate. The lifting component 16 basically does not move up or down, enabling the adjustment device 1 to self-lock.

[0156] It is understood that the mounting flange 136, on the side of the driven wheel 132 facing away from the transmission part 1323 along the axial direction of the driven wheel 132, is not limited to abutting against the fastener 134. Exemplarily, the mounting flange 136 is spaced apart from the fastener 134 on the side of the driven wheel 132 facing away from the transmission part 1323 along the axial direction of the driven wheel 132. When the driven wheel 132 rotates, the mounting flange 136 rotates, and the fastener 134 rotates with the driven wheel 132. The mounting flange 136 and the fastener 134 do not contact each other, reducing wear between the mounting flange 136 and the fastener 134 and reducing resistance to the rotation of the driven wheel 132.

[0157] 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 corresponding transmission mechanism 14 and a corresponding bracket 11.

[0158] It should be noted that at least two transmission mechanisms 14 are located in the same drive mechanism 12.

[0159] It should be noted that there are at least two stents 11.

[0160] For example, the number of lifting mechanisms 13 is two, three, or four.

[0161] For example, the number of lifting mechanisms 13 for the short-tail seat is two.

[0162] For example, the short-tailed seat cushion is a single-person seat cushion.

[0163] For example, the number of lifting mechanisms 13 of the long-tail cushion is two.

[0164] For example, the long-tailed cushion is a multi-person cushion.

[0165] For example, the seat cushion is provided on at least two lifting mechanisms 13.

[0166] In this embodiment, there are at least two lifting mechanisms 13. Each lifting mechanism 13 is provided with a corresponding transmission mechanism 14 and a corresponding bracket 11. At least two lifting mechanisms 13 are driven to lift by a drive mechanism 12. The at least two lifting positions facilitate the lifting of a large seat cushion. The adjustment device 1 has a wide range of applications.

[0167] 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.

[0168] For example, the number of lifting mechanisms 13 for the short-tail seat is one.

[0169] In some embodiments, the axial direction of the driving wheel 122 is parallel to the axial direction of the driven wheel 132.

[0170] In this embodiment, the axial direction of the driving wheel 122 is parallel to the axial direction of the driven wheel 132, and the first cable 141 and the second cable 142 are parallel, which reduces the interference between the first cable 141 and the second cable 142 and is conducive to the uniform force on the driving wheel 122 and the driven wheel 132.

[0171] It is understood that the axis of the driving wheel 122 is not limited to being parallel to the axis of the driven wheel 132. For example, the axis of the driving wheel 122 intersects the axis of the driven wheel 132.

[0172] In some embodiments, please refer to Figures 1-5 The driving wheel 122 is located on one side of the driven wheel 132 along the radial direction of the driven wheel 132.

[0173] In this embodiment, the driving wheel 122 is located on one side of the driven wheel 132 along the radial direction of the driven wheel 132. The driving wheel 122 is set up using the space on the radial side of the driven wheel 132, which reduces the space occupied by the driving wheel 122 in the axial direction of the adjusting device 1 along the driven wheel 132, reduces the axial dimension of the adjusting device 1 in the driven wheel 132, and saves the space required to install the adjusting device 1.

[0174] It is understood that the driving wheel 122 is not limited to being located on one side of the driven wheel 132 along the radial direction of the driven wheel 132. Exemplarily, the driving wheel 122 is located on one side of the driven wheel 132 along the axial direction of the driven wheel 132.

[0175] In some embodiments, the lifting mechanism 13 is made of metal.

[0176] For example, the transmission mechanism 14 is made of metal.

[0177] For example, the drive wheel 122 is made of metal.

[0178] In this embodiment, the lifting mechanism 13 is made of metal, which facilitates the recycling of the lifting mechanism 13, improves the reusability of the components of the regulating device 1, and is beneficial to environmental protection.

[0179] In some embodiments, please refer to Figures 1-5 The transmission mechanism 14 includes a protective sleeve 145, which is respectively sleeved on the first cable 141 and the second cable 142 to protect the first cable 141 and the second cable 142.

[0180] It should be noted that the first cable 141 can move within the protective sleeve 145, and the second cable 142 can move within the protective sleeve 145.

[0181] In some embodiments, please refer to Figures 1-5 The transmission mechanism 14 includes a wiring harness stabilizer 146, a protective sleeve 145 connected to the wiring harness stabilizer 146, and the wiring harness stabilizer 146 connected to the first seat plate of the seat cushion to limit the position of the protective sleeve 145.

[0182] In some embodiments, the seat cushion further includes a sponge and a covering, which are disposed on the first seat plate.

[0183] For example, the drive mechanism 12 is disposed on the first seat to rise and fall together with the first seat.

[0184] In some embodiments, the cushion further includes a second seat plate, which is connected to the bracket 11.

[0185] For example, the first seat and the second seat are covered with sponge and skin.

[0186] For example, the grip 1216 is located on the side of the second seat away from the first seat.

[0187] In some embodiments, please refer to Figure 6 and Figure 7 The adjusting device 1 includes a first wire harness stabilizer 151, which is disposed on the drive wheel 122. The first wire harness stabilizer 151 has a first constraint tooth 1511, which is partially located in the first mounting groove 1221. The first constraint tooth 1511 is located on the outside of the first cable 141 and the second cable 142 along the radial direction of the drive wheel 122 to constrain the position of the first cable 141 and the second cable 142 in the first mounting groove 1221.

[0188] It should be noted that each first mounting slot 1221 is provided with a first constraint tooth 1511.

[0189] In this embodiment, the first constraint tooth 1511 is partially located within the first mounting groove 1221. The first constraint tooth 1511 is located radially along the drive wheel 122 outside the first cable 141 and the second cable 142 to constrain the positions of the first cable 141 and the second cable 142 within the first mounting groove 1221. The first constraint tooth 1511 can press the first cable 141 and the second cable 142 into the first mounting groove 1221, reducing the movement space of the first cable 141 and the second cable 142 within the first mounting groove 1221. The first wire harness stabilizer 151 stabilizes the positions of the first cable 141 and the second cable 142 wound on the drive wheel 122, reducing the likelihood of the first cable 141 getting knotted, crossed, or interfering within the first mounting groove 1221 during the rotation of the drive wheel 122, and reducing the likelihood of the second cable 142 getting knotted, crossed, or interfering within the first mounting groove 1221 during the rotation of the drive wheel 122. This reduces the possibility of the adjustment device 1 malfunctioning and is beneficial to the operation of the adjustment device 1. The first cable 141 and the second cable 142, which are wound on the drive wheel 122, are stabilized by the first cable harness stabilizer 151, which facilitates the control of the position of the first cable 141 and the second cable 142 during the assembly process and facilitates the installation of the first cable 141 and the second cable 142.

[0190] It is understandable that the adjustment device 1 may not be equipped with the first harness stabilizer 151.

[0191] In some embodiments, please refer to Figure 6 and Figure 7The adjusting device 1 includes a second wire harness stabilizer 152, which is disposed on the driven wheel 132. The second wire harness stabilizer 152 has a second constraint tooth 1521, which is partially located in the second mounting groove 1321. The second constraint tooth 1521 is located on the outside of the first cable 141 and the second cable 142 along the radial direction of the driving wheel 122 to constrain the position of the first cable 141 and the second cable 142 in the first mounting groove 1221.

[0192] It should be noted that each second mounting slot 1321 is provided with a second constraint tooth 1521.

[0193] In this embodiment, the second constraint tooth 1521 is partially located within the second mounting groove 1321. The second constraint tooth 1521 is located radially along the driven wheel 132 outside the first cable 141 and the second cable 142 to constrain the positions of the first cable 141 and the second cable 142 within the second mounting groove 1321. The second constraint tooth 1521 can press the first cable 141 and the second cable 142 into the second mounting groove 1321, reducing the movement space of the first cable 141 and the second cable 142 within the second mounting groove 1321. The second wire harness stabilizer 152 stabilizes the positions of the first cable 141 and the second cable 142 wound on the driven wheel 132, reducing the likelihood of the first cable 141 getting knotted, crossed, or interfering within the second mounting groove 1321 during the rotation of the driven wheel 132, and reducing the possibility of the adjusting device 1 malfunctioning, which is beneficial to the operation of the adjusting device 1. The second harness stabilizer 152 stabilizes the position of the first cable 141 and the second cable 142 wound on the driven wheel 132, which facilitates the control of the position of the first cable 141 and the second cable 142 during the assembly process and facilitates the installation of the first cable 141 and the second cable 142.

[0194] It is understandable that the adjustment device 1 may not be equipped with a second harness stabilizer 152.

[0195] In some embodiments, please refer to Figure 6 and Figure 7 The end of the cable has a first limiting part 143 and a second limiting part 144. The driving wheel 122 has a first limiting groove 1222 and the driven wheel 132 has a second limiting groove 1322. The first limiting part 143 is located in the first limiting groove 1222 to restrict the end of the cable from disengaging from the driving wheel 122, and the second limiting part 144 is located in the second limiting groove 1322 to restrict the end of the cable from disengaging from the driven wheel 132.

[0196] For example, the first limiting groove 1222 is located inside the first mounting groove 1221 along the radial direction of the drive wheel 122.

[0197] For example, the second limiting groove 1322 is located inside the second mounting groove 1321 along the radial direction of the driven wheel 132.

[0198] For example, the first limiting groove 1222 is connected to the second limiting groove 1322.

[0199] For example, the first limiting groove 1222 abuts against the first limiting part 143 along the groove wall on the radially outer side of the drive wheel 122.

[0200] For example, the groove walls of the first limiting groove 1222 on opposite sides of the drive wheel 122 in the circumferential direction respectively abut against the first limiting part 143.

[0201] For example, the second limiting groove 1322 abuts against the second limiting part 144 along the groove wall on the radially outer side of the drive wheel 122.

[0202] For example, the groove walls of the second limiting groove 1322 on opposite sides of the drive wheel 122 in the circumferential direction respectively abut against the second limiting part 144.

[0203] For example, the first limiting groove 1222 is open on the side of the drive wheel 122 that is radially away from the first mounting groove 1221.

[0204] For example, the second limiting groove 1322 is open on the side of the drive wheel 122 that is radially away from the second mounting groove 1321.

[0205] In this embodiment, the first limiting part 143 is located within the first limiting groove 1222 to prevent the end of the cable from disengaging from the driving wheel 122, and the second limiting part 144 is located within the second limiting groove 1322 to prevent the end of the cable from disengaging from the driven wheel 132. Through the cooperation of the first limiting part 143 with the first limiting groove 1222 and the cooperation of the second limiting part 144 with the second limiting groove 1322, the cable can maintain cooperation with both the driven wheel 132 and the driving wheel 122, reducing the possibility of the adjusting device 1 failing. The first limiting part 143 can be directly placed within the first limiting groove 1222, and the second limiting part 144 can be directly placed within the second limiting groove 1322, facilitating the assembly of the first cable 141 and the second cable 142 with the driving wheel 122 and the driven wheel 132, respectively.

[0206] It is understood that the ends of the cable are not limited to having the first limiting part 143 and the second limiting part 144, the driving wheel 122 is not limited to having the first limiting groove 1222, and the driven wheel 132 is not limited to having the second limiting groove 1322. For example, one end of the cable is tied to the driving wheel 122, and the other end of the cable is tied to the driven wheel 132.

[0207] For example, the driving wheel 122 has a first limiting part 143, the driven wheel 132 has a second limiting part 144, and the two ends of the cable are respectively connected to the first limiting part 143 and the second limiting part 144.

[0208] 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 is in the closed state, the upper side of the support portion abuts against the first sub-frame 111.

[0209] In some embodiments, 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 buckle. When the seat is closed, the hook 113 engages with the buckle to restrict the movement of the second sub-frame 112. When the seat is open, the hook 113 disengages from the buckle.

[0210] In some embodiments, the axial direction of the connector 131 is arranged in the vertical direction.

[0211] For example, the axial direction of the connector 131 is parallel to the vertical direction.

[0212] In some embodiments, the second seat is connected to the bracket 11.

[0213] For example, the adjustment device 1 includes a fixed plate, which is connected to the bracket 11, and a second seat plate is connected to the fixed plate.
