In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0038] like Figure 1-Figure 4As shown, in this embodiment, the hidden flip seat structure includes a fixed seat 1, a mounting base 2, a clamping base 3, an adjusting member and a rotating member 4. Among them, the fixed seat 1 is installed on the frame 100, the mounting base 2 is arranged on the fixed seat 1, the mounting base 2 is provided with a connecting hole 21, the clamping base 3 is slidably arranged on the mounting base 2, and the adjusting member passes through the connecting hole 21 and is connected to the clamping base 3. The rotating member 4 is connected to the seat cushion 200 and is rotatably arranged between the clamping base 3 and the mounting base 2, so that the seat cushion 200 can rotate freely relative to the frame 100 and has a storage state and a use state. When the seat cushion 200 is in the storage state, the use surface of the seat cushion 200 is hidden in the frame 100, and when the seat cushion 200 is in the use state, the use surface of the seat cushion 200 is arranged away from the frame 100 and faces outward.

[0039] Specifically, the fixing seat 1 is a U-shaped structure, the fixing seat 1 is arranged at the bottom of the edge of the frame 100, the mounting base 2 is an inverted T-shaped structure, the mounting base 2 is arranged on the frame 100 through the fixing seat 1, and the clamping base 3 is slidably located on the mounting base 2 and can be close to or away from the mounting base 2. The adjusting member is set as a screw, the adjusting member passes through the connecting hole 21 of the mounting base 2 and is connected to the clamping base 3, and the adjusting member can rotate relative to the clamping base 3 to adjust the distance between the clamping base 3 and the mounting base 2. One end of the rotating member 4 is installed at the edge of the bottom support of the seat cushion 200, and the other end of the rotating member 4 is movably arranged in the rotating space formed between the clamping base 3 and the mounting base 2. Under the action of the adjusting member, the clamping base 3 slides relative to the mounting base 2 and can be rotatably connected with the rotating member 4. The working principle of the hidden flip seat cushion structure is as follows: the seat cushion 200 is in a storage state by default, and the use surface of the seat cushion 200 is hidden in the frame 100. When the seat cushion 200 needs to be used, the adjustment member is screwed to adjust the rotating member 4 to be slightly loose relative to the mounting base 2 and the clamping base 3, and the seat cushion 200 is flipped upward so that the angle between the seat cushion 200 and the frame 100 is greater than or equal to 90 degrees. Then, the seat cushion 200 is rotated 180 degrees relative to the frame 100, and finally the seat cushion 200 is flipped downward, and the use surface of the seat cushion 200 is set outward. At this time, the seat cushion is in a use state, and the adjustment member is screwed to lock the rotating member 4, which is not easy to flip, has good stability, and is convenient for passengers to sit. The hidden flip seat cushion structure is hidden and stored when the seat cushion 200 is not in use, has good aesthetics, and has a simple structure. The tightness of the seat cushion 200 can be adjusted by the adjustment member, and it is easy to disassemble.

[0040] Further, continue to refer to Figure 1-Figure 4, the rotating part 4 is made of nylon material, and the mounting base 2 and the clamping base 3 are both made of aluminum alloy material. Specifically, the surface of the mounting base 2 and the clamping base 3 is treated with fine leather grain, which allows the rotating part 4 to maintain a uniform and smooth rotation while ensuring strength. The various components of the hidden flip cushion structure are integrally cast and injection molded, and do not require subsequent processing such as welding and grinding of sheet metal parts. The base made of aluminum alloy and the rotating part 4 made of nylon rotate together. Compared with the traditional sheet metal stamping and welding structure, it reduces the structural deformation and tooling positioning tolerance caused by welding. At the same time, it avoids deformation and locking of the sheet metal through screw extrusion installation or shaking due to excessive gaps, and there is no rust, paint corrosion, locking, or abnormal noise caused by friction of sheet metal parts.

[0041] Further, continue to refer to Figure 1-Figure 4 The clamping base 3 is provided with an adjustment portion 31 corresponding to the connection hole 21, and the adjustment member passes through the connection hole 21 and is rotatably provided on the adjustment portion 31 to adjust the distance between the clamping base 3 and the mounting base 2. Specifically, the adjustment portion 31 and the clamping base 3 are integrally formed by casting or other methods, and the adjustment portion 31 is provided with an adjustment hole, and the adjustment hole is provided with an internal thread, and the outer periphery of the adjustment member is provided with an external thread, and the adjustment member and the adjustment portion 31 are matched with the external thread and the internal thread, and the adjustment member rotates relative to the fixed base and can move along the axial direction of the adjustment hole to adjust the distance between the clamping base 3 and the mounting base 2, so that the tightness of the rotating member 4 can be adjusted to facilitate the switching of the seat cushion 200 between the use state and the storage state, and at the same time, it is convenient for disassembly and replacement.

[0042] Further, continue to refer to Figure 1-Figure 4 , two limiting baffles 22 are respectively arranged on both sides of the mounting base 2, and the two limiting baffles 22 are arranged oppositely and in parallel, and the clamping base 3 can slide relative to the mounting base 2, so that the clamping base 3 can be slidably clamped between the two limiting baffles 22. Specifically, the two limiting baffles 22 and the mounting base 2 are integrally formed by casting or other methods, and the clamping base 3 slides with the mounting base 2 and can be located between the two limiting baffles 22, which plays a certain limiting role on the clamping base 3, ensuring that the clamping base 3 can slide in the direction close to or away from the mounting base 2.

[0043] Further, continue to refer to Figure 1-Figure 4The clamping base 3 includes a clamping portion 32 and a sliding portion 33. The clamping portion 32 can press the rotating member 4 against the mounting base 2. The limiting baffle 22 is provided with a slide groove 221. The sliding portion 33 is located in the slide groove 221 and can slide relative to the slide groove 221 to adjust the distance between the clamping portion 32 and the mounting base 2. Specifically, there are two slide grooves 221. Both sides of the sliding portion 33 are respectively slidably arranged in the two slide grooves 221. Under the action of the two slide grooves 221, the sliding portion 33 can be guided to slide relative to the mounting base 2. At the same time, the slide groove 221 plays a certain role in limiting the sliding portion 33 in the vertical direction, ensuring that the clamping base 3 always slides along the depth direction of the slide groove 221 to approach or move away from the mounting base 2.

[0044] Further, continue to refer to Figure 1-Figure 4 The rotating member 4 includes a fixing portion 41 and a ball head 42. The fixing portion 41 is arranged on the seat cushion 200. The mounting base 2 and the clamping base 3 respectively have a first recessed portion 23 and a second recessed portion 34. The ball head 42 is rotatably arranged between the first recessed portion 23 and the second recessed portion 34. Specifically, the first connecting member is a bolt. The fixing portion 41 is provided with a first through hole 411. The edge of the seat cushion 200 is provided with a mounting hole. The first connecting member passes through the first through hole 411 and is connected to the mounting hole. The fixing portion 41 is fixedly installed at the edge of the seat cushion 200 through the first connecting member. Conversely, the seat cushion 200 can be removed by removing the first connecting member, which is convenient for replacement. The first recessed portion 23 and the second recessed portion 34 can respectively abut against the ball head portion 42 of the rotating member 4. Under the action of the adjusting member, the first recessed portion 23 and the second recessed portion 34 can clamp the ball head portion 42, so that the rotating member 4 is in a tightened state and fixed. Similarly, the adjusting member can adjust the distance between the clamping base 3 and the mounting base 2, so that the ball head portion 42 can rotate and cooperate with the first recessed portion 23 and the second recessed portion 34, so that the seat cushion 200 can switch freely between the use state and the storage state. The first recessed portion 23 and the second recessed portion 34 play a certain role in preventing the ball head portion 42 from disengaging during the rotation process and affecting normal use.

[0045] Further, continue to refer to Figure 1-Figure 4 The edge of the seat cushion 200 and the frame 100 are respectively provided with a first avoidance groove 201 and a second avoidance groove 101. When the seat cushion 200 switches between the storage state and the use state, the first avoidance groove 201 and the second avoidance groove 101 are used to avoid the clamping base 3 and the mounting base 2. Specifically, the first avoidance groove 201 and the second avoidance groove 101 are both U-shaped structures. When the seat cushion 200 switches between the use state and the storage state, the first avoidance groove 201 and the second avoidance groove 101 can ensure that the seat cushion 200 and the frame 100 avoid the clamping base 3 and the mounting base 2. The hidden flip seat cushion structure is compact and reasonable to assemble without affecting normal use.

[0046] Further, continue to refer to Figure 1-Figure 4 The hidden flip seat structure also includes a second connecting member, the fixing seat 1 is provided with a second through hole 11, the mounting base 2 is also provided with a connecting hole, and the second connecting member passes through the second through hole 11 and is connected to the connecting hole. Specifically, the second connecting member is a bolt, and the mounting base 2 is fixed to the fixing seat 1 of the frame 100 through the second connecting member, which is easy to install and convenient to disassemble, replace and repair.
