[0039] Please see Figure 1 This application provides a seat, which includes a seat cushion assembly 100 and a backrest. The backrest is rotatably connected to the seat cushion assembly 100 to facilitate angle adjustment for providing more comfortable back support. For example, it can be used to sit on the seat cushion assembly 100 so that the user's back can rest against the backrest.

[0040] Please see Figures 2 to 4 In some embodiments, the seat cushion assembly 100 includes a seat body 110, a backrest mounting base 130, a first toggle button 150, a locking structure 170, and a first resilient limiting member 190.

[0041] The backrest mounting base 130 is rotatably connected to the seat body 110, and the backrest is connected to the backrest mounting base 130 so as to rotate synchronously with the backrest mounting base 130, thereby allowing the angle of the backrest to be adjusted. For example, a user can sit on the seat body 110 and lean against the backrest.

[0042] As an example, the seat cushion assembly 100 may also include a first pivot that can be connected to the seat body 110, and the backrest mounting base 130 is rotatably connected to the first pivot to rotate about the axis of the first pivot.

[0043] The first toggle button 150 is rotatably connected to the seat body 110 and has a locked position and an unlocked position. The first toggle button 150 can be rotated to the locked position and the unlocked position. When the first toggle button 150 is in the locked position, the backrest mounting base 130 and the seat body 110 are locked and fixed. When the first toggle button 150 is in the unlocked position, the backrest mounting base 130 and the seat body 110 are unlocked. At this time, the backrest mounting base 130 can be rotated to adjust the rotation angle.

[0044] The first toggle button 150 is provided with a first limiting groove 1511 and a second limiting groove 1513, which are used to cooperate with the first elastic limiting member 190.

[0045] The seat 110 is provided with a first mounting groove 211, and the first toggle button 150 is rotatably located on one side of the groove opening of the first mounting groove 211.

[0046] As an example, the seat 110 may have a first side and a second side facing away from each other. The user can sit on the first side, the first mounting groove 211 may be provided on the second side, and the first toggle button 150, the locking structure 170 and the first elastic limiting member 190 are all located on the second side.

[0047] The locking structure 170 includes a first end and a second end opposite to each other. The first end is connected to the first toggle button 150, and the second end is movably connected to the seat 110. The locking structure 170 is configured to drive the second end to move as the first toggle button 150 rotates. That is, when the second toggle button 270 rotates, it can pull the first end to rotate synchronously, and when the first end rotates, it can pull the second end to move.

[0048] The second end can be used for locking and unlocking between the seat 110 and the backrest mounting base 130.

[0049] The first elastic limiting member 190 is disposed in the first mounting groove 211 and abuts against the seat 110 and the first toggle button 150. The elastic member 191 and the limiting member 193 can continuously abut against the first toggle button 150 under the action of elastic force, and slide into the first limiting groove 1511 or the second limiting groove 1513 as the first toggle button 150 rotates.

[0050] When the first toggle button 150 is in the locked position, the first elastic limiting member 190 is located in the first limiting groove 1511, and the second end locks the seat 110 and the backrest mounting base 130. When the first toggle button 150 is in the unlocked position, the first elastic limiting member 190 is located in the second limiting groove 1513, and the second end unlocks the seat 110 and the backrest mounting base 130. Thus, the seat cushion assembly 100 of this embodiment can control the movement of the locking structure 170 by opening the first toggle button 150 to control the locking state between the seat 110 and the backrest connecting base 210. When the seat 110 and the backrest mounting base 130 are unlocked, the first elastic limiting member 190 can be located in the second limiting groove 1513, thereby limiting the first toggle button 150 to the current position. At this time, the user can flexibly adjust the angle of the backrest without having to continuously hold the first toggle button 150, making the operation more convenient and improving the user experience.

[0051] It should be noted that there are several options for the locking structure 170.

[0052] As an example, the locking structure 170 can adopt a linkage-slider structure, with the first end located on the linkage and the second end located on the slider, so that the linkage can follow the movement of the first toggle button 150 to push the second end back and forth, so that the second end can be locked and unlocked.

[0053] The locking structure 170 can also adopt other structures, as shown in the following embodiments.

[0054] In some embodiments, the locking structure 170 may include a first control line 171 and a locking element 173.

[0055] The first control line 171 can be connected between the first toggle button 150 and the locking member 173. The locking member 173 is movably connected to the seat body 110, with its first end located on the first control line 171 and its second end located on the locking member 173. The first control line 171 is configured to pull the locking member 173 to move as the first toggle button 150 rotates to the locking position, thereby unlocking the seat body 110 and the backrest connecting seat 210. Thus, the first control line 171 can be controlled by rotating the first toggle button 150 to achieve unlocking. Compared with control structures made of other rigid materials, this embodiment, by using the first control line 171, allows for more flexible arrangement of the positions of the first toggle button 150 and the locking member 173 on the seat body 110, and can save on the manufacturing cost of the seat cushion assembly 100.

[0056] As an example, the first control line 171 can be connected to the side of the first toggle button 150 opposite to the seat body 110. The first toggle button 150 can have a first rotation direction. When the first toggle button 150 rotates in the first rotation direction, the first toggle button 150 rotates from the locked position to the unlocked position, and the first elastic limiting member 190 disengages from the first limiting groove 1511. Since the length of the first control line 171 is fixed, during the rotation of the first toggle button 150, the first toggle button 150 can continuously pull the first control line 171 to drive the locking member 173 to move. When the first elastic limiting member 190 slides into the second limiting groove 1513, the locking member 173 unlocks the backrest mounting base 130, and the user can release the first toggle button 150 and flexibly adjust the rotation angle of the backrest.

[0057] In some embodiments, the first control line 171 may adopt a flexible structure. Compared with control structures made of other rigid materials, the flexible first control line 171 helps to arrange the positions of the first toggle button 150 and the locking member 173 on the seat body 110 more flexibly, and can save the manufacturing cost of the seat cushion assembly 100.

[0058] As an example, the first control line 171 can be made of steel wire rope, wire harness rope made of steel wire or other flexible rope. The outside of the first control line 171 can be covered with plastic, which helps to improve the structural strength of the first control line 171 while ensuring the flexibility of the first control line 171, and helps to reduce the interference between the first control line 171 and other structural components.

[0059] In some embodiments, the backrest mounting base 130 is provided with a plurality of fixing parts 131, which are adapted to be positioned in the movement path of the locking member 173 as the backrest mounting base 130 rotates.

[0060] As an example, the fixing part 131 can be a fixing hole or a fixing groove. As the backrest mounting base 130 rotates, one of the fixing parts 131 is opposite to the locking member 173. When the locking member 173 is in the locked position, the locking member 173 can be inserted into a fixing part 131 to fix the seat 110 and the backrest mounting base 130.

[0061] The locking structure 170 may further include a first elastic reset member 175, which abuts against the seat 110 and the locking member 173, for moving the locking member 173 toward the fixing part 131. The first toggle button 150 moves to the locked position, and the locking member 173 and the fixing part 131 are connected to lock the seat 110 and the backrest mounting base 130.

[0062] As an example, the seat 110 may have a first receiving groove and two connecting holes. The two connecting holes may be located on the sidewalls of the groove on opposite sides of the first receiving groove. The locking member 173 may pass through the two connecting holes and the receiving groove. The first elastic reset member 175 may be a spring and sleeved on the locking member 173. The spring may abut against the sidewall of the first receiving groove and the locking member 173 to push the locking member 173 out of the connecting hole. The fixing part 131 may have one opposite to the connecting hole. The locking member 173 may be inserted into the fixing part 131, so that the locking member 173 can lock the seat 110 and the backrest mounting base 130.

[0063] When the first toggle button 150 is rotated in the first rotation direction, the locking member 173 can be pulled out of the retractable connection hole to disengage from the fixing part 131, thereby unlocking the seat 110 and the backrest mounting base 130.

[0064] When the first toggle button 150 rotates in the second rotation direction, the first elastic limiting member 190 disengages from the first limiting groove 1511. At this time, the elastic reset member pushes the locking member 173 to move under the action of elastic force to connect the fixing part 131, and can drive the first toggle button 150 to rotate to the locked position. The second rotation direction can be opposite to the first rotation direction.

[0065] In some embodiments, the seat cushion assembly 100 may further include a connecting seat 210, which can be connected to the seat body 110. The first mounting groove 211 can be provided on the connecting seat 210, thereby avoiding the need to directly process the first mounting groove 211 on the seat body 110 and reducing the manufacturing difficulty.

[0066] The first toggle switch 150 is rotatably connected to the connector 210.

[0067] As an example, the connector 210 may be provided with a second receiving groove, a first hole, and a second hole, which may be located on the groove sidewalls on opposite sides of the second receiving groove. The seat assembly 100 may also include a second rotating shaft, which may be inserted into the first hole and the second hole. The connector 210 is located in the second receiving groove and is rotatably connected to the second rotating shaft to rotate about the axis of the second rotating shaft.

[0068] In some embodiments, the connector 210 may be provided with a wire hole 213, through which the first control wire 171 is movably passed. This provides guidance for the first control wire 171, helps the first control wire 171 to have a more defined movement trajectory, and helps the first toggle button 150 to pull the first control wire 171 more effectively.

[0069] As an example, the connector 210 may have a protruding wire portion spaced apart from the sidewall of the second receiving groove, and a wire hole 213 may be provided in the wire portion. The wire portion may also have an opening that communicates with the wire hole 213, so as to install the first control wire 171 in the wire hole 213.

[0070] In some embodiments, the locking structure 170 may further include a conduit that can be connected to the seat 110. The first control line 171 is movably passed through the conduit, thereby restricting the movement of the first control line 171 within the conduit and helping to avoid interference with other structural components when the first control line 171 moves.

[0071] As an example, a conduit can be connected between the conductor section and the seat 110, and both ends of the first control line 171 can be exposed in the conduit to facilitate connection of the locking member 173 and the first toggle button 150.

[0072] In some embodiments, the first elastic limiting member 190 may include an elastic member 191 and a limiting member 193.

[0073] The limiting member 193 is movably disposed within the first mounting groove 211.

[0074] The elastic member 191 is located in the first mounting groove 211 and abuts against the limiting member 193 and the seat 110. It is used to push the elastic member 191 against the first toggle button 150, so that the limiting member 193 can always be kept in contact with the first toggle button 150. This helps the limiting member 193 to slide more smoothly into the first limiting groove 1511 or the second limiting groove 1513 as the first toggle button 150 slides.

[0075] When the locking structure 170 locks the seat 110 and the backrest mounting base 130, the limiting member 193 abuts against the first limiting groove 1511 to position the first toggle button 150 in the current position and prevent the first toggle button 150 from shaking and generating noise.

[0076] When the locking structure 170 unlocks the seat 110 and the backrest mounting base 130, the limiting member 193 abuts against the second limiting groove 1513 to position the first toggle button 150 in the current position, so that the user does not need to hold the first toggle button 150 at all times, and the user can freely adjust the rotation angle of the backrest.

[0077] In some embodiments, the first toggle button 150 may include a rotating part 151 and a toggle part 153. The toggle part 153 is connected to one side of the rotating part 151 and extends outward. The rotating part 151 is rotatably connected to the seat 110. The first limiting groove 1511 and the second limiting groove 1513 are both provided on the rotating part 151, so that the user can toggle the toggle part 153 to drive the rotating part 151 to rotate, making the operation more convenient.

[0078] Please see Figures 4 to 5 In some embodiments, the seat cushion assembly 100 may further include a drive member 230, a linkage member 250, a second toggle button 270, and a second control line 290.

[0079] The drive end of the drive component 230 is connected to the seat 110 and is used to drive the seat 110 to rise and fall.

[0080] The drive unit 230 may be equipped with a start button 231, which can control the start and stop of the drive unit 230. When the start button 231 is pressed, the drive unit 230 can drive the seat cushion assembly 100 to rise and fall. When the start button 231 is released, the drive unit 230 locks the seat cushion assembly 100 in the current position.

[0081] As an example, the seat cushion assembly 100 may also include a support foot, and a support frame may be connected to the side of the drive member 230 away from the seat body 110 for supporting the seat cushion assembly 100 and the backrest. The drive member 230 may drive the seat body 110 to rise and fall relative to the support foot.

[0082] The linkage 250 is rotatably connected to the seat 110 and is positioned opposite to the start button 231. The second toggle button 270 is movably connected to the seat 110. One end of the second control line 290 is connected to the second toggle button 270, and the other end is connected to the linkage 250. The second control line 290 is configured to rotate the linkage 250 as the second toggle button 270 rotates, thereby pressing the start button 231. The drive member 230 can drive the seat 110 to rise and fall. Thus, the user can toggle the second toggle button 270 to drive the linkage 250 to rotate downwards via the second control line 290 to press the button. At this time, the drive member 230 can drive the seat 110 to rise and fall.

[0083] The structure and driving method of the second toggle button 270 and the second control line 290 can be referred to the first toggle button 150 and the first control component, and will not be repeated here. The difference is that the second toggle button 270 does not need to be provided with a limit groove (first limit groove 1511 and second limit groove 1513), so the user can adjust the lifting height of the seat 110 more flexibly. The second control line 290 also does not need to be provided with a locking component 173.

[0084] In some embodiments, the seat cushion assembly 100 further includes a second elastic reset member 310, which is connected between the linkage member 250 and the seat body 110. The second elastic reset member 310 is used to drive the linkage member 250 to release the start button 231. Thus, when the user releases the second toggle button 270, the second elastic reset member 310 can drive the linkage member 250 to release the start button 231. The drive member 230 fixes the seat body 110 in the current position. After the linkage member 250 releases the start button 231, it can also drive the second toggle button 270 to rotate in the opposite direction to achieve a reset.
