[0022] In order to make the purpose, technical solutions and effects of this application clearer and more specific, this application is further described in detail below with reference to the accompanying drawings and examples.

[0023] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0024] The seat of the present application is a foldable seat, which can be installed in, but not limited to, cars, trains, buses, airplanes, ships and other means of transportation.

[0025] See also Figure 1 , Figure 1 This is a structural diagram of an embodiment of a seat provided by this application. Figure 1 As shown, the chair 10 includes a seat 1, a backrest 2, and a motion mechanism 3. The seat 1 and the backrest 2 are connected by the motion mechanism 3, and the motion mechanism 3 can move away from the seat 1. The seat 1 has a seat surface, and the backrest 2 is rotatably connected to the motion mechanism 3 so that the backrest 2 can rotate around the motion mechanism 3 away from or toward the seat surface.

[0026] Since the chair back 2 can rotate around the motion mechanism 3 away from or close to the seat surface, the seat 10 can be folded and the folded seat can be opened; further, the motion mechanism 3 can move in a direction away from the seat 1, wherein during this movement, the distance between the seat 1 and the chair back 2 increases, so that when the chair back 2 rotates around the motion mechanism 3, the rotation space of the chair back 2 is increased, thereby increasing the rotation angle of the chair back 2, which can improve the flatness of the folded seat.

[0027] In some embodiments, the chair seat 1 includes a first connection end located on the seat surface, and the movement mechanism 3 is connected to the first connection end.

[0028] In a specific embodiment, a connecting frame (not shown in the figure) with a running track can be provided on the side of the first connecting end, and the moving mechanism is provided on the connecting frame and can move on the connecting frame in a direction away from and close to the seat 1.

[0029] In another specific embodiment, Figure 2 As shown, the first connection end is provided with a seat-limiting space 11, and the motion mechanism 3 is disposed in the seat-limiting space 11. The motion mechanism 3 is capable of moving in a defined direction within the seat-limiting space 11. The defined directions include a first movement direction and a second movement direction. The first movement direction is a direction away from the seat 1, and the second movement direction is a direction toward the seat 1. In other words, the motion mechanism 3 can move in directions away from and toward the seat 1 within the seat-limiting space 11.

[0030] The seat limit space 11 is provided to bring the distance between the end of the backrest 2 close to the seat 1 and the first connection end as close as possible when the seat 10 is in the open state. In addition, when the seat is in the folded state, the backrest 2 and the seat 1 are folded flat as much as possible.

[0031] Please refer to Figure 1 and Figure 3 , Figure 3 This is a structural diagram of an embodiment of a seat in an open state. Figure 1 The seat 10 in the embodiment is in a folded state. In one implementation scenario, the seat 10 is currently in an open state. If the seat 10 in the open state needs to be folded, the motion mechanism 3 can be controlled to move in the first motion direction in the seat limit space 11 to spatially separate the chair back 2 and the seat 1, thereby increasing the flippable angle of the chair back 2. In one embodiment, when the motion mechanism 3 moves in the first motion direction in the seat limit space 11, the chair back 2 is controlled to rotate in a direction close to the seat surface to fold the seat 10 so that the seat 10 is in a folded state. Of course, in other embodiments, the motion mechanism 3 can also be controlled to move in the first motion direction in the seat limit space 11 to the first posture (such as Figure 1 That is, the chair back 2 can be controlled to rotate toward the seat surface while the motion mechanism 3 is controlled to move in the first motion direction. Alternatively, the motion mechanism 3 can be controlled to move in the first motion direction to the first posture, and then the chair back 2 can be controlled to rotate toward the seat surface.

[0032] In another implementation scenario, the seat 10 is currently in a folded state. In this folded state, if the seat 10 in the folded state needs to be opened, the seat back 2 can be controlled to rotate in a direction away from the seat surface, and when the seat back 2 rotates in a direction away from the seat surface, the motion mechanism 3 is controlled to move in a second motion direction close to the seat in the seat limit space 11 to open the seat 10 and make it appear in an open state.

[0033] Of course, the chair back 2 may be controlled to rotate in a direction away from the seat surface first, and when the chair back 2 rotates by a preset angle, the motion mechanism 3 may be controlled to move in a second direction close to the seat until it moves to the second posture.

[0034] As can be seen from the above, the motion mechanism 3 can move to a first posture and a second posture. When the motion mechanism 3 is in the first posture, the distance between the second connection end and the first connection end of the chair back 2 and the motion mechanism 3 is greater than or equal to a first preset threshold. When the motion mechanism 3 is in the second posture, the distance between the second connection end and the first connection end of the chair back 2 and the motion mechanism 3 is less than or equal to a second preset threshold.

[0035] The first preset threshold is greater than the second preset threshold.

[0036] The first preset threshold and the second preset threshold can be set according to actual needs. For example, in order to make the backrest 2 and the seat 1 of the seat 10 in the open state look like they are integrally formed, the second preset threshold can be set to a value near 0.

[0037] In some embodiments, see Figure 4 , Figure 4 FIG. 1 is a schematic diagram of the exploded structure of a seat embodiment. Figure 4 As shown, the chair back 2 includes a chair back body 21 and a driving assembly 22 connected to the chair back body 21 . The driving assembly 22 is used to drive the chair back 2 to rotate toward or away from the seat surface.

[0038] In one embodiment, see Figure 5 , Figure 5 This is a schematic diagram of the structure of the drive assembly provided in this application. The drive assembly 22 includes a first drive member 221 and a rotating shaft 222. The first drive member 221 is connected to the end of the rotating shaft 222. The chair back body 21 is connected to the rotating shaft 222. The first drive member 221 is used to drive the rotating shaft 222 to rotate, thereby driving the chair back 2 to rotate during the rotation process. Optionally, the number of first drive members 221 can be one or two. When the number of first drive members 221 is one, the first drive member 221 is disposed at one end of the rotating shaft 222. When the number of first drive members 221 is two, the first drive members 221 are disposed at both ends of the rotating shaft 222.

[0039] In a specific embodiment, at least one protrusion with a through hole in the middle (not shown in the figure) can be provided at one end of the chair back body 21 close to the movement mechanism 3, and the protrusion can be connected to the rotating shaft 222 so that the first driving member 221 drives the chair back 2 to rotate when the driving shaft 222 rotates.

[0040] In other embodiments, the drive assembly 22 may also be a hydraulic drive assembly or an electromagnetic drive assembly, which can be selected according to actual needs and is not specifically limited here.

[0041] In some embodiments, please refer to Figure 4 The motion mechanism 3 includes a second driving member 31 and a supporting member 32. The driving assembly 22 and the second driving member 31 are respectively connected to the supporting member 32. In one embodiment, through holes are provided at both ends of the supporting member 32, and the first driving member 221 of the driving assembly 22 is disposed within the through holes. When there is one first driving member 221, the first driving member 221 is disposed within the through hole at one end, and the end of the rotating shaft 222, which is away from the first driving member 221, is disposed within the through hole at the other end. When there are two first driving members 221, each first driving member 221 is disposed in the through hole at the corresponding end.

[0042] In one embodiment, a thread hole (not shown in the figure) is provided on the supporting member 32, and the second driving member 31 is a screw mechanism, which is connected to the thread hole. The movement of the motion mechanism 3 is achieved through the cooperation of the screw mechanism and the thread hole.

[0043] In one specific embodiment, Figure 2 As shown, the first connecting end of the seat 1 is further provided with a drive hidden space 12 for hiding the second drive member 31 .

[0044] In some embodiments, see Figure 4 In order to adjust the height of the seat 1, a lifting mechanism can be set at the bottom of the seat 1, wherein the lifting mechanism includes a lifting unit 13 and a base 4 connected to each other.

[0045] Furthermore, in order to increase the activity space in a vehicle, for example, to increase the activity space in a vehicle, a hiding mechanism may be provided on the vehicle floor, and the seat 10 may be hidden by the hiding mechanism, for example, the seat 10 may be hidden in the vehicle floor.

[0046] In some embodiments, see Figure 6 and Figure 7 , Figure 6 This is a partial structural diagram of an embodiment of a vehicle provided by this application. Figure 7 1 is a schematic diagram of a state in which the seat is hidden in the hidden space. In this embodiment, the vehicle 60 includes the above-mentioned seat and a hiding mechanism 6 provided on the bottom 5 of the vehicle.

[0047] The hidden mechanism 6 includes a hidden groove 61 and a hidden limit space 62 arranged adjacent to each other. The hidden limit space 62 is arranged at the outer edge of the top of one side of the hidden groove 61. The hidden limit space 62 is provided with a partition 621. The seat is arranged in the hidden groove 61. The partition 621 can be moved in a direction away from the second limit space to a preset position (such as Figure 7 As shown), to form a hidden space with the hidden groove 61.

[0048] The means of transportation in this embodiment may be, but is not limited to, a car, and may also be a train, a bus, an airplane, a ship or other means of transportation.

[0049] The structural arrangement of this embodiment can completely hide the seat in the hidden space, and from the surface, the bottom of the vehicle is flat. It can be seen that this application can greatly increase the activity space in the vehicle.

[0050] The above description of the various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced with each other and will not be repeated herein for the sake of brevity.
