It should be understood that these embodiments are provided to make the disclosure of this application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

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

[0042] Specifically, the seat includes: a seat body 70, a leg rest body 10, a sliding plate 20, a pallet assembly 30 and a first drive unit 40. The leg rest body 10 is connected to the seat body 70, and the leg rest body 10 is provided with a storage cavity 11 with an open end. The sliding plate 20 is slidably connected to the leg rest body 10, and the sliding plate 20 has a first storage position that is completely stored in the storage cavity 11, and has a plurality of working positions that are at least partially located outside the storage cavity 11. The pallet assembly 30 is arranged outside the storage cavity 11, and the pallet assembly 30 is connected to the sliding plate 20 through a connecting assembly 80. The sliding plate 20 can drive the pallet assembly 30 to be movably arranged, and the pallet assembly 30 is used to carry a target object. The first drive unit 40 is arranged in the storage cavity 11, and the first drive unit 40 is used to drive the sliding plate 20 to drive the pallet assembly 30 to switch between the first storage position and each working position.

[0043] In the embodiment of the present 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 driving unit 40 drives the sliding plate 20 to switch between multiple positions inside and outside the storage cavity 11. In other words, the distance between the support plate assembly 30 and the seat body 70 is adjustable. The support plate assembly 30 in the above embodiment can be adjusted to meet the needs of passengers of different heights or leg lengths by adjusting the distance between the support plate assembly 30 and the seat body 70, providing passengers with more comfortable leg support.

[0044] It should be noted that the target object that the support plate assembly 30 is used to carry is generally the legs of the passenger, but can also be other items.

[0045] In an exemplary embodiment of the present application, the first driving part 40 is connected to the sliding plate 20 through a transmission mechanism 60, and the transmission mechanism 60 is arranged in the storage chamber 11. The transmission mechanism 60 includes: a screw assembly and a guide assembly. The screw assembly includes a screw body 61 and a sliding nut 62. The screw body 61 is arranged in the storage chamber 11 along the length direction of the leg support body 10. The sliding nut 62 is threadedly connected to the screw body 61. The first driving part 40 is connected to the screw body 61. The first driving part 40 is used to drive the screw body 61 to rotate. The guide assembly includes a guide rod 63 and a guide slider 64. The guide rod 63 is arranged in the storage chamber 11 along the length direction of the leg support body 10. The guide slider 64 is slidably connected to the guide rod 63. Among them, 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 embodiment of the present application, the first drive unit 40 drives the screw body 61 to rotate, causing the sliding nut 62 to move along the length of the screw body 61. The guide assembly is used to limit the rotation of the sliding nut 62 relative to the screw body 61, thereby causing the sliding plate 20 to move along the length of the leg support body 10. The sliding nut 62 is threadedly connected to the screw body 61. While the sliding nut 62 moves relative to the screw body 61, it is self-locking through the threads, thereby driving the support plate assembly 30 to lock in any position. In other words, the position of the support plate assembly 30 can be adjusted steplessly, which can better accommodate the needs of passengers of different heights or leg lengths.

[0047] like Figure 2 As shown, the leg support body 10 is provided with a storage cavity 11 with an open end, and the storage cavity 11 is extended along the length direction of the leg support body 10. The screw assembly and the guide assembly are arranged in the storage cavity 11, and the screw assembly and the guide assembly are arranged at intervals along the width direction of the storage cavity 11. Two first connecting seats 14 are provided in the storage cavity 11 of the leg support body 10, and the two first connecting seats 14 are arranged at intervals along the length direction of the storage cavity 11. The screw body 61 is connected between the two first connecting seats 14, and the screw body is rotatably connected to the first connecting seats 14. The sliding nut 62 is sleeved on the screw body 61 and is threadedly connected to the screw body 61. The first driving part 40 is a motor, and the first driving part 40 is connected to one end of the screw body, and is used to drive the screw body 61 to rotate relative to the first connecting seat 14. Two second connecting seats 15 are provided within the storage chamber 11 of the leg support body 10. The two second connecting seats 15 are spaced apart along the length of the storage chamber 11, and a guide rod 63 is fixedly connected between the two second connecting seats 15. A 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 drive unit 40 drives the screw body 61 to rotate relative to the first connecting seat 14, thereby driving the sliding plate 20 to move along the length of the storage chamber 11.

[0048] Preferably, the side surface of the first connecting seat 14 slides against one side surface of the sliding plate 20, and the side surface of the second connecting seat 15 slides against the other side surface of the sliding plate 20, that is, when the sliding plate 20 moves along the length direction of the storage chamber 11, the first connecting seat 14 and the second connecting seat 15 provide side support for the sliding plate 20 to enable the sliding plate 20 to move more stably.

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

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

[0051] In an exemplary embodiment of the present application, a side of the leg support body 10 close to the support plate assembly 30 is provided with an avoidance opening 13, and the avoidance opening 13 is connected to the storage cavity 11, and a part of the connecting assembly 80 passes through the avoidance opening 13 and is connected to the sliding plate 20.

[0052] In the embodiment of the present application, the support plate assembly 30 is connected to the sliding plate 20 via the connecting assembly 80. A portion of the connecting assembly 80 extends into the storage chamber 11 through the top opening of the storage chamber 11, thereby connecting the support plate assembly 30 to the top of the sliding plate 20. The provision of the avoidance opening 13 increases the connection area between the support plate assembly 30 and the sliding plate 20, thereby ensuring a stable connection between the two. Furthermore, the provision of the avoidance opening 13 serves to a certain extent as a limit, guiding the movement of the leg support body 10 along the length of the avoidance opening 13.

[0053] like Figure 2 、 Figure 3 As shown, the top surface of the leg rest body 10 is provided with two avoidance openings 13, and the two avoidance openings 13 are spaced apart along the width direction of the leg rest body 10. Each avoidance opening 13 is extended along the length direction of the leg rest body 10, and each avoidance opening 13 extends to the opening end of the storage cavity 11, and each avoidance opening 13 is connected to the storage cavity 11. Among them, each avoidance opening 13 is a rectangular structure, and the corresponding connecting assembly 80 is a rectangular structure as a whole. Specifically, the connecting assembly 80 is fixedly connected to the top surface of the sliding plate 20, and part of the connecting assembly 80 extends to the outside of the storage cavity 11 through the avoidance opening 13 to connect with the support plate assembly 30. Among them, the support plate assembly 30 is located directly above the connecting assembly 80 and can block the connecting assembly 80 to make the overall structure of the seat more beautiful and enhance the visual effect.

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

[0055] In the embodiment of the present application, the support plate assembly 30 is detachably connected to the sliding plate 20 to avoid cleaning and replacement of the support plate 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 is provided with a mounting cavity 811 with an opening on one side. The top of the mounting base 81 is provided with at least one mounting opening 812 for a portion of the support plate assembly 30 to extend into the mounting cavity 811. The locking member 83 is slidably arranged in the mounting cavity 811. The locking member 83 has a first position that avoids the mounting opening 812 and a second position that blocks the mounting opening 812. When the locking member 83 is in the second position, the locking member 83 locks the support plate assembly 30. A portion of the drive plate 84 is arranged 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 embodiment of the present application, the locking member 83 is disposed within the mounting cavity 811 of the mounting base 81, and the driving plate 84 drives the locking member 83 to slide within the mounting cavity 811 to lock and unlock the pallet assembly 30. The locking member 83 and the driving plate 84 are designed to be interlocked, allowing the operator to lock and unlock the pallet assembly 30 by controlling the driving plate 84, resulting in a simple structure and easy operation.

[0058] like Figure 1 、 Figure 2 As shown, an installation space is formed between the support plate assembly 30 and the leg support body 10, and the drive plate 84 is located in the installation space. The mounting seat 81 is arranged along the length direction of the leg support body 10, and the mounting cavity 811 is extended along the length direction of the mounting seat 81. The locking member 83 is arranged in the mounting cavity 811, and the locking member 83 can slide along the length direction of the mounting cavity 811. The driving plate 84 can be manually driven to move along the length direction of the leg support body 10 to achieve switching of the locking member 83 between the first position and the second position. The driving plate 84 can also be electrically driven to move along the length direction of the leg support body 10 to achieve switching of the locking member 83 between the first position and the second position.

[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 keep the locking member 83 in the second position.

[0060] In the embodiment of the present application, the drive plate 84 is manually operated to compress the elastic member 86, so that the locking member 83 moves from the second position to the first position, thereby unlocking the support plate assembly 30. After the external force disappears, the drive plate 84 moves in the opposite direction under the action of the restoring force of the elastic member 86, thereby driving the locking member 83 to move to the second position, thereby locking the support plate assembly 30. After the drive plate 84 is operated by external force to adjust the locking member 83 to the first position, the locking member 83 can automatically return to its original position under the drive of the elastic member 86, stably locking the support plate assembly 30. There is no need to provide an additional structure for locking the locking member 83 in position, thereby simplifying the operation process and locking structure.

[0061] like Figure 4 As shown, there are two mounting seats 81, which are spaced apart along the width of the sliding plate 20, and each mounting seat 81 extends along the length of the sliding plate 20. The bottom of the mounting seat 81 is connected to the sliding plate 20, and the mounting seat 81 is provided with a mounting cavity 811 with one side open, which extends along the length of the mounting seat 81. The top of the mounting seat 81 is provided with two mounting openings 812, which are spaced apart along the length of the mounting seat 81, and each mounting opening 812 is connected to the mounting cavity 811.

[0062] like Figure 4 As shown, the fixing rod 88 is disposed in the mounting cavity 811 and is fixedly connected to the mounting seat 81. The fixing rod 88 extends along the length of the mounting cavity 811. A fixing seat 89 is provided in the mounting cavity 811 and is fixedly connected to the inner bottom wall of the mounting cavity 811. The fixing seat 89 is sleeved on the fixing rod 88. An extrusion plate 87 is sleeved on the fixing rod 88 and is slidably connected to the extrusion plate 87. The elastic member 86 is a tension and compression spring. The elastic member 86 is sleeved on the fixing rod 88. One end of the elastic member 86 is connected to the fixing seat 89, and the other end of the elastic member 86 is connected to the extrusion plate 87. The elastic member 86 is always in a compressed state to provide a preload force to keep the locking member 83 in the second position. Two locking members 83 are sleeved on the fixing rod 88. The locking member 83 is slidably connected to the fixing rod 88, and the fixing seat 89 is located between the two locking members 83. The drive plate 84 is provided outside the mounting cavity 811. One end of the drive plate 84 is connected to one of the locking members 83 via a connecting plate 85. The other end of the drive plate 84 is connected to the other locking member 83 via a connecting plate 85. The extrusion plate 87 is connected to the drive plate 84. A mounting space is formed between the support plate assembly 30 and the leg support body 10. The drive plate 84 is located within the mounting 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. The drive rod 841 is located within the mounting space, and the end of the drive rod 841 is arranged near the end of the mounting space to facilitate the operator to push the drive rod 841.

[0063] like Figure 4 As shown, in the absence of external force, the locking member 83 is in the second position, and the locking member 83 cooperates with the support plate assembly 30, that is, the locking member 83 is locked with the support plate assembly 30. When the support plate assembly 30 needs to be removed, the driving rod 841 is manually pushed toward the seat body 70, and the squeezing plate 87 compresses the elastic member 86, and the locking member 83 moves toward the seat body 70, so that the locking member 83 avoids the installation opening 812, that is, the locking member 83 is disengaged from the support plate assembly 30, and the support plate assembly 30 is unlocked.

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

[0065] In an exemplary embodiment of the present application, the support plate assembly 30 includes: a support plate body 33 and a cushion 32 . The support plate body 33 is detachably connected to the mounting seat 81 , and the cushion 32 is connected to a side of the support plate body 33 facing away from the mounting seat 81 .

[0066] In the embodiment of the present application, the provision of the soft cushion 32 improves the comfort of the support plate assembly 30 and provides more comfortable leg support for the passenger.

[0067] In an exemplary embodiment of the present application, the support plate assembly 30 further includes a connector 31, which includes a first connecting section and a second connecting section. The first connecting section and the second connecting section are arranged vertically. The first connecting section is connected to the support plate body 33, and the second connecting section can extend into the mounting cavity 811 through the mounting opening 812, so that an insertion space is formed between the second connecting section and the inner top wall of the mounting seat 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 the top surface of the second connecting section.

[0068] In the embodiment of the present application, an insertion space is formed between the second connecting section of the connecting member 31 and the inner top wall of the mounting seat 81. The locking member 83 extends into the insertion space and presses against the second connecting section, thereby locking the support plate assembly 30. The pressing contact between the locking member 83 and the second connecting section provides a larger contact area, making the locking more stable.

[0069] like Figure 2 、 Figure 4 、 Figure 5As shown, two mounting seats 81 are provided on the sliding plate 20, and each mounting seat 81 is provided with two mounting openings 812, that is, the support plate assembly 30 is connected to the sliding plate 20 via four connecting members 31. The connecting member 31 is an L-shaped structure, and the connecting member 31 includes a first connecting section and a second connecting section. The first connecting section is connected to the support plate body 33, and the first connecting section is arranged perpendicular to the support plate body 33, and the second connecting section is arranged parallel to the support plate body 33. The second connecting section is used to extend into the mounting cavity 811 through the mounting openings 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 is an L-shaped structure. The locking member 83 includes a third connecting segment and a fourth connecting segment. The third connecting segment is provided with a sliding hole. The third connecting end is sleeved on the fixed rod 88 through the sliding hole. The fourth connecting segment of the locking member 83 is arranged parallel to the second connecting segment of the connecting member 31.
