[0040] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0041] Combination Figures 1 to 6 As shown, according to a specific embodiment of this application, a seat is provided.

[0042] Specifically, the seat includes: a seat body 70, a leg rest body 10, a sliding plate 20, a tray assembly 30, and a first drive unit 40. The leg rest body 10 is connected to the seat body 70 and has a storage cavity 11 with one open end. The sliding plate 20 is slidably connected to the leg rest body 10 and has a first storage position that is completely retracted into the storage cavity 11, and multiple working positions that are at least partially located outside the storage cavity 11. The tray assembly 30 is located outside the storage cavity 11 and is connected to the sliding plate 20 via a connecting component 80. The sliding plate 20 can move the tray assembly 30, and the tray assembly 30 is used to carry a target object. The first drive unit 40 is located inside the storage cavity 11 and is used to drive the sliding plate 20 to switch the tray assembly 30 between the first storage position and each working position.

[0043] In the embodiments of this application, the sliding plate 20 is slidably connected to the leg rest body 10, and the support plate assembly 30 is connected to the sliding plate 20. The support plate assembly 30 is used to support the passenger's legs. The first drive unit 40 drives the sliding plate 20 to switch between multiple positions inside and outside the storage cavity 11, that is, the distance between the support plate assembly 30 and the seat body 70 is adjustable. In the above solution, the support plate assembly 30, by adjusting the distance between the support plate assembly 30 and the seat body 70, meets the needs of passengers of different heights or leg lengths, providing passengers with more comfortable leg support.

[0044] It should be noted that the pallet assembly 30 is generally used to support the passenger's legs, but it can also support other items.

[0045] In one exemplary embodiment of this application, the first driving unit 40 is connected to the sliding plate 20 via a transmission mechanism 60. The transmission mechanism 60 is disposed within the receiving cavity 11 and includes a lead screw assembly and a guide assembly. The lead screw assembly includes a lead screw body 61 and a sliding nut 62. The lead screw body 61 is disposed within the receiving cavity 11 along the length direction of the leg support body 10. The sliding nut 62 is threadedly connected to the lead screw body 61. The first driving unit 40 is connected to the lead screw body 61 and is used to drive the lead screw body 61 to rotate. The guide assembly includes a guide rod 63 and a guide slider 64. The guide rod 63 is disposed within the receiving cavity 11 along the length direction of the leg support body 10, and the guide slider 64 is slidably connected to the guide rod 63. One side of the sliding plate 20 is connected to the sliding nut 62, and the other side of the sliding plate 20 is connected to the guide slider 64.

[0046] In the embodiments of this application, the first drive unit 40 drives the lead screw body 61 to rotate, so that the sliding nut 62 moves along the length direction of the lead screw body 61. The guide component is used to limit the rotation of the sliding nut 62 relative to the lead screw body 61, thereby causing the sliding plate 20 to move along the length direction of the leg support body 10. The sliding nut 62 and the lead screw body 61 are threadedly connected. While the sliding nut 62 moves relative to the lead screw body 61, it achieves self-locking through the thread, thereby enabling the support plate assembly 30 to be locked in any position, that is, to achieve stepless adjustment of the position of the support plate assembly 30, which can better adapt to the needs of passengers of different heights or leg lengths.

[0047] like Figure 2 As shown, the leg support body 10 has a storage cavity 11 with one open end, which extends along the length of the leg support body 10. A lead screw assembly and a guide assembly are disposed within the storage cavity 11, spaced apart along the width of the storage cavity 11. Two first connecting seats 14 are provided within the storage cavity 11 of the leg support body 10, spaced apart along the length of the storage cavity 11. The lead screw body 61 is connected between the two first connecting seats 14, and is rotatably connected to the first connecting seats 14. A sliding nut 62 is sleeved on the lead screw body 61 and threadedly connected to it. A first drive unit 40 is a motor, connected to one end of the lead screw body, used to drive the lead screw body 61 to rotate relative to the first connecting seats 14. The leg support body 10 has two second connecting seats 15 inside its storage cavity 11. The two second connecting seats 15 are spaced apart along the length of the storage cavity 11, and the guide rod 63 is fixedly connected between the two second connecting seats 15. The guide slider 64 is sleeved on the guide rod 63 and is slidably disposed relative to the guide rod 63. One side of the sliding plate 20 is connected to the sliding nut 62, and the other side of the sliding plate 20 is connected to the guide slider 64. The first driving part 40 drives the lead screw body 61 to rotate relative to the first connecting seat 14, thereby causing the sliding plate 20 to move along the length of the storage cavity 11.

[0048] Preferably, the side of the first connecting seat 14 slides against one side of the sliding plate 20, and the side of the second connecting seat 15 slides against the other side of the sliding plate 20. That is, during the process of the sliding plate 20 moving along the length of the storage cavity 11, the first connecting seat 14 and the second connecting seat 15 provide lateral support for the sliding plate 20 so that the sliding plate 20 moves more stably.

[0049] The first drive unit 40 can be matched with a control panel, which has multiple gears. Each gear corresponds to a different number of rotations of the first drive unit 40. By activating different gears, the position of the sliding plate 20 can be adjusted.

[0050] As an alternative implementation, the transmission mechanism 60 may also include two sets of lead screw assemblies, which are spaced apart along the width direction of the receiving cavity 11, and the connection method of each lead screw assembly is the same as that of the lead screw assembly in the above embodiment.

[0051] In one exemplary embodiment of this application, the leg support body 10 has a clearance opening 13 on the side near the support plate assembly 30. The clearance opening 13 is connected to the storage cavity 11, and part of the connecting component 80 passes through the clearance opening 13 and connects to the sliding plate 20.

[0052] In the embodiments of this application, the tray assembly 30 is connected to the sliding plate 20 via a connecting component 80. A portion of the connecting component 80 extends into the receiving cavity 11 through the top opening of the receiving cavity 11, meaning the tray assembly 30 is connected to the top of the sliding plate 20. By providing a clearance opening 13, the connection area between the tray assembly 30 and the sliding plate 20 is increased, ensuring a stable connection. Furthermore, the clearance opening 13 serves as a limiting feature, guiding the leg support body 10 to move along the length of the clearance opening 13.

[0053] like Figure 2 , Figure 3 As shown, the top surface of the leg rest body 10 is provided with two clearance openings 13. The two clearance openings 13 are spaced apart along the width direction of the leg rest body 10, and each clearance opening 13 extends along the length direction of the leg rest body 10, extending to the opening end of the storage cavity 11, and each clearance opening 13 is connected to the storage cavity 11. Each clearance opening 13 is rectangular, and the corresponding connecting component 80 is also rectangular. Specifically, the connecting component 80 is fixedly connected to the top surface of the sliding plate 20, and part of the connecting component 80 extends out of the storage cavity 11 through the clearance openings 13 to connect with the tray assembly 30. The tray assembly 30 is located directly above the connecting component 80, which can cover the connecting component 80, making the overall structure of the seat more aesthetically pleasing and improving the visual effect.

[0054] Preferably, the tray assembly 30 is detachably connected to the sliding plate 20 via the connecting assembly 80.

[0055] In embodiments of this application, the tray assembly 30 is detachably connected to the sliding plate 20 to avoid cleaning and replacement of the tray assembly 30.

[0056] Exemplarily, the connecting assembly 80 includes: a mounting base 81, a locking member 83, and a drive plate 84. The bottom of the mounting base 81 is connected to the sliding plate 20. The mounting base 81 has a mounting cavity 811 with an opening on one side, and the top of the mounting base 81 has at least one mounting port 812 for a portion of the tray assembly 30 to extend into the mounting cavity 811. The locking member 83 is slidably disposed within the mounting cavity 811. The locking member 83 has a first position that avoids the mounting port 812 and a second position that blocks the mounting port 812. When the locking member 83 is in the second position, the locking member 83 locks the tray assembly 30. A portion of the drive plate 84 is disposed outside the mounting cavity 811. The drive plate 84 is connected to the locking member 83 via a connecting plate 85. The drive plate 84 is used to drive the locking member 83 to switch between the first position and the second position.

[0057] In the embodiments of this application, the locking member 83 is disposed within the mounting cavity 811 of the mounting base 81, and the drive plate 84 drives the locking member 83 to slide within the mounting cavity 811 to lock and unlock the tray assembly 30. The locking member 83 and the drive plate 84 are designed to move together, allowing the operator to lock and unlock the tray assembly 30 by controlling the drive plate 84. The structure is simple and easy to operate.

[0058] like Figure 1 , Figure 2 As shown, an installation space is formed between the tray assembly 30 and the leg support body 10, and the drive plate 84 is located within this installation space. The mounting base 81 is disposed along the length direction of the leg support body 10, and the mounting cavity 811 extends along the length direction of the mounting base 81. A locking member 83 is disposed within the mounting cavity 811 and can slide along the length direction of the mounting cavity 811. The locking member 83 can be switched between a first position and a second position by manually driving the drive plate 84 along the length direction of the leg support body 10. The locking member 83 can also be switched between a first position and a second position by electrically driving the drive plate 84 along the length direction of the leg support body 10.

[0059] Furthermore, the mounting cavity 811 extends along the length of the mounting base 81, and the drive plate 84 is used to drive the locking member 83 to slide along the length of the mounting cavity 811. The connecting assembly 80 also includes a fixing rod 88 and an elastic member 86. The fixing rod 88 is fixedly disposed within the mounting cavity 811 and extends along the length of the mounting cavity 811. The locking member 83 is slidably connected to the fixing rod 88. The elastic member 86 is sleeved on the fixing rod 88. One end of the elastic member 86 is connected to the mounting cavity 811, and the other end of the elastic member 86 is connected to the drive plate 84. The elastic member 86 is used to provide a preload force to position the locking member 83 in the second position.

[0060] In the embodiments of this application, the drive plate 84 is manually operated to compress the elastic element 86, causing the locking element 83 to move from the second position to the first position, thereby unlocking the tray assembly 30. After the external force disappears, the drive plate 84 moves in the opposite direction under the restoring force of the elastic element 86, thereby driving the locking element 83 to move to the second position, thereby locking the tray assembly 30. After the external force operates the drive plate 84 to adjust the locking element 83 to the first position, the locking element 83 can automatically reset under the drive of the elastic element 86, stably locking the tray assembly 30. There is no need to set up an additional structure for locking the position of the locking element 83, simplifying the operation process and locking structure.

[0061] like Figure 4 As shown, there are two mounting bases 81, which are spaced apart along the width direction of the sliding plate 20. Each mounting base 81 extends along the length direction of the sliding plate 20. The bottom of the mounting base 81 is connected to the sliding plate 20. The mounting base 81 has a mounting cavity 811 with an opening on one side, which extends along the length direction of the mounting base 81. The top of the mounting base 81 has two mounting ports 812, which are spaced apart along the length direction of the mounting base 81. Each mounting port 812 communicates with the mounting cavity 811.

[0062] like Figure 4 As shown, a fixing rod 88 is disposed within the mounting cavity 811 and is fixedly connected to the mounting base 81. The fixing rod 88 extends along the length of the mounting cavity 811. A fixing base 89 is disposed within the mounting cavity 811 and is fixedly connected to the inner bottom wall of the mounting cavity 811. The fixing base 89 is sleeved on the fixing rod 88. A compression plate 87 is sleeved on the fixing rod 88 and is slidably connected to the fixing rod 88. An elastic element 86 is a tension / compression spring, sleeved on the fixing rod 88. One end of the elastic element 86 is connected to the fixing base 89, and the other end of the elastic element 86 is connected to the compression plate 87. The elastic element 86 is always in a compressed state to provide a preload force for placing the locking element 83 in the second position. Two locking elements 83 are sleeved on the fixing rod 88 and are slidably connected to the fixing rod 88. The fixing base 89 is located between the two locking elements 83. In addition to the mounting cavity 811, the drive plate 84 has one end connected to one of the locking members 83 via a connecting plate 85, and the other end connected to another locking member 83 via a connecting plate 85. A pressing plate 87 is also connected to the drive plate 84. An installation space is formed between the support plate assembly 30 and the leg support body 10, and the drive plate 84 is located within this installation space. A drive rod 841 is provided on the side of the drive plate 84 away from the seat body 70. The drive rod 841 extends along the length of the drive plate 84 and is located within the installation space. The end of the drive rod 841 is positioned close to the end of the installation space to facilitate pushing the drive rod 841 by the operator.

[0063] like Figure 4 As shown, under no external force, the locking member 83 is in the second position, and the locking member 83 cooperates with the tray assembly 30, that is, the locking member 83 is locked to the tray assembly 30. When it is necessary to remove the tray assembly 30, the drive rod 841 is manually pushed to move towards the seat body 70, the compression plate 87 compresses the elastic member 86, and the locking member 83 moves towards the seat body 70 so that the locking member 83 avoids the mounting port 812, that is, the locking member 83 disengages from the tray assembly 30, thereby unlocking the tray assembly 30.

[0064] Specifically, the locking member 83 and the tray assembly 30 can be locked by plugging or by pressing.

[0065] In one exemplary embodiment of this application, the tray assembly 30 includes a tray body 33 and a cushion 32, the tray body 33 being detachably connected to a mounting base 81, and the cushion 32 being connected to the side of the tray body 33 opposite to the mounting base 81.

[0066] In the embodiments of this application, the provision of the cushion 32 enhances the comfort of the tray assembly 30, providing passengers with more comfortable leg support.

[0067] In one exemplary embodiment of this application, the tray assembly 30 further includes a connector 31, which includes a first connecting segment and a second connecting segment. The first connecting segment and the second connecting segment are vertically arranged. The first connecting segment is connected to the tray body 33, and the second connecting segment can extend into the mounting cavity 811 through the mounting port 812, so that an insertion space is formed between the second connecting segment and the inner top wall of the mounting base 81. When the locking member 83 is in the second position, the locking member 83 extends into the insertion space, and the bottom surface of the locking member 83 abuts against the top surface of the second connecting segment.

[0068] In the embodiments of this application, an insertion space is formed between the second connecting section of the connector 31 and the inner top wall of the mounting base 81. The locking member 83 extends into this insertion space and presses against the second connecting section, thereby locking the tray assembly 30. The locking member 83 presses against the second connecting section, resulting in a larger contact area and more stable locking.

[0069] like Figure 2 , Figure 4 , Figure 5As shown, the sliding plate 20 is provided with two mounting seats 81, and each mounting seat 81 is provided with two mounting ports 812. That is, the tray assembly 30 is connected to the sliding plate 20 through four connectors 31. The connectors 31 have an L-shaped structure and include a first connecting section and a second connecting section. The first connecting section is connected to the tray body 33 and is perpendicular to the tray body 33. The second connecting section is parallel to the tray body 33 and is used to extend into the mounting cavity 811 through the mounting ports 812 so that an insertion space is formed between the inner top walls of the second connecting section mounting seats 81. The locking member 83 has an L-shaped structure and includes a third connecting section and a fourth connecting section. The third connecting section has a sliding hole, and the third connecting end is sleeved on the fixed rod 88 through the sliding hole. The fourth connecting section of the locking member 83 is arranged parallel to the second connecting section of the connecting member 31. The fourth connecting section extends into the insertion space, and the bottom surface of the fourth connecting section abuts against the top surface of the second connecting section to lock the sliding plate 20 and the support plate assembly 30.

[0070] In one exemplary embodiment of this application, a mounting structure 12 is provided at one end of the leg rest body 10. The leg rest body 10 is rotatably connected to the front side of the seat body 70 through the mounting structure 12. The seat also includes a second drive unit 50, which is connected to the mounting structure 12. The second drive unit 50 is used to drive the leg rest body 10 to rotate around a preset axis so that the leg rest body 10 has an unfolded position at a first angle to the bearing surface of the seat body 70, and a second folded position at a second angle to the bearing surface.

[0071] In the embodiments of this application, the second drive unit 50 can drive the leg rest body 10 to rotate around a preset axis so that the leg rest body 10 and the bearing surface of the seat body 70 form different angles. That is, the passenger can adjust the angle between the leg rest body 10 and the seat body 70 according to his / her own needs, thereby meeting the different needs of the user.

[0072] like Figure 1 , Figure 2 , Figure 6 As shown, one end of the leg rest body 10 is provided with a mounting structure 12, which is a connecting block formed on the leg rest body 10. The connecting block has a connecting hole that extends through the width of the leg rest body 10. A rotating shaft 16 is provided in the connecting hole of the mounting structure 12, and the rotating shaft 16 is fixedly connected to the mounting structure 12. Two fixing plates 71 are provided on the front side of the seat body 70, and the two fixing plates 71 are spaced apart along the width of the seat body 70. The mounting structure 12 is located between the two fixing plates 71 and is rotatably connected to the fixing plates 71 through the rotating shaft 16. The second drive unit 50 is a motor, and the drive end of the second drive unit 50 is connected to the rotating shaft 16. The second drive unit 50 is used to drive the rotating shaft 16 to rotate relative to the fixing plates 71, thereby realizing the rotation of the leg rest body 10 and the seat body 70.
