Technical Field
[0001] This application relates to the field of vehicle technology, specifically to a table assembly, a seat, and a vehicle. Background Technology
[0002] As users continuously improve their vehicle experience, the loading rate of small tables on the seatbacks is constantly increasing. In related technologies, when the table is in the unfolded state relative to the seatback, the angle between the table and the back of the seatback is fixed. When the user adjusts the angle between the seatback and the horizontal plane, the supporting surface of the table will tilt relative to the horizontal plane, causing items to slip off and affecting the user experience. Utility Model Content
[0003] This application provides a tabletop assembly, a seat, and a vehicle to address the problem of how to keep the load-bearing surface of the tabletop horizontal.
[0004] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:
[0005] In a first aspect, embodiments of this application provide a tabletop assembly, which includes a fixed base, a tabletop, a connecting rod assembly, and an adjusting structure. The fixed base has a first surface area. The tabletop has a bearing surface. One end of the connecting rod assembly is rotatably connected to the fixed base. The adjusting structure is connected to the other end of the connecting rod assembly and the tabletop, enabling the tabletop assembly to move between an unfolded state and a folded state; the adjusting structure can adjust the angle between the bearing surface and the first surface area when the tabletop assembly is in the unfolded state.
[0006] In some possible implementations of the first aspect, the linkage assembly includes a first link comprising a first end and a second end opposite to each other; the first end is rotatably connected to a fixed base, and the axes of rotation of both extend along a first direction. The adjustment structure includes a ratchet, a first swing arm, a second swing arm, and a pawl. The ratchet is connected to the second end and has a plurality of circumferentially arranged ratchet teeth. One end of the first swing arm is rotatably connected to a tabletop, and the other end is rotatably connected to the ratchet. One end of the second swing arm is slidably connected to the tabletop along a second direction, and the other end is rotatably connected to the ratchet; the second direction is perpendicular to the first direction. The pawl is rotatably connected to the tabletop and is capable of engaging between two ratchet teeth and disengaging from the ratchet.
[0007] In some possible implementations of the first aspect, the other end of the first rocker arm has a first through hole and a first opening communicating with the first through hole. A ratchet is disposed within the first through hole, and the first opening exposes a portion of the ratchet teeth; a portion of the pawl can pass through the first opening and engage between two ratchet teeth. The second end is located on one side of the other end of the first rocker arm and faces one end face of the ratchet.
[0008] In some possible implementations of the first aspect, the adjusting structure further includes a first rotating shaft. The first rotating shaft is connected to one end face of the ratchet and to the second end face; one end of the second swing arm is sleeved on the first rotating shaft and located between the first swing arm and the second end face.
[0009] In some possible implementations of the first aspect, the adjustment structure further includes a limiting member located on the side of the first swing arm opposite to the second end and connected to the ratchet, with a portion of the limiting member located on the outer periphery of the first through hole.
[0010] In some possible implementations of the first aspect, the tabletop includes a tabletop body and a sliding support. A bearing surface is formed on the tabletop body, and the sliding support is located on the side opposite to the bearing surface and fixed to the tabletop body. The sliding support has a groove extending in a second direction. The adjustment structure also includes a slide rod connected to one end of a second swing arm. The slide rod is fitted and accommodated within the groove and is capable of sliding and rotating relative to the sliding support.
[0011] In some possible implementations of the first aspect, the adjustment structure further includes a second pivot and a handle. The second pivot comprises a first segment, a second segment, and a third segment connected in sequence, the first and third segments being parallel to each other. The end of the first segment away from the third segment is connected to a pawl, and the third segment is rotatably connected to the tabletop. The handle is connected to the end of the third segment away from the first segment and is at least partially located on the outer periphery of the tabletop.
[0012] In some possible implementations of the first aspect, the adjustment structure also includes an elastic element, one end of which is fixed relative to the pawl and the other end of which is fixed relative to the table. The elastic element is used to apply a force to the pawl that points towards the ratchet.
[0013] In some possible implementations of the first aspect, the linkage assembly further includes a second link, one end of which is rotatably connected to the fixed base and the other end of which is rotatably connected to the table.
[0014] Secondly, this application provides a seat, which includes a backrest and a table assembly, wherein the table assembly is the table assembly described in any of the above implementations, and a fixing seat is fixed to the backrest.
[0015] Thirdly, embodiments of this application provide a vehicle, which includes a body and a seat. The seat is the aforementioned seat, and the seat is disposed on the body.
[0016] The table assembly, seat, and vehicle provided in this application have the following beneficial effects:
[0017] The tabletop assembly provided in this application allows the tabletop assembly to move between an unfolded state and a folded state by rotatably connecting one end of the linkage assembly to the fixed base and connecting the adjustment structure to the other end of the linkage assembly and the tabletop itself. In this way, users can unfold the tabletop assembly to place items on its supporting surface, or fold it to increase the usable space.
[0018] Based on this, by enabling the adjustment structure to adjust the angle between the tabletop's bearing surface and the first surface area, when the seat back rotates relative to the cushion, causing the angle between the first surface area and the horizontal plane to change, the adjustment structure can adjust the angle between the bearing surface and the horizontal plane, thereby ensuring that the bearing surface is in a roughly horizontal state to prevent items from falling and improve the user experience (as shown in the figure).
[0019] The beneficial technical effects of the seat and vehicle provided in this application are the same as those of the table assembly provided in this application, and will not be repeated here. Attached Figure Description

[0046] As vehicles become increasingly luxurious and users demand a better driving experience, the loading rate of seatback tray tables is constantly rising. Please refer to the following: Figures 1-3 , Figure 1A schematic diagram of the structure of the seat 100 provided for related technologies when the table assembly 10 is in a folded state. Figure 2 for Figure 1 The diagram shown illustrates the structure of the seat 100 when the table assembly 10 is in the unfolded state. Figure 3 for Figure 1 The diagram shows the structure of the table assembly 10 of the seat 100. The seat 100 includes a seat cushion 20, a backrest 30, and a table assembly 10. The table assembly 10 includes a fixed base 11, a linkage assembly 12, and a table 13. The fixed base 11 is fixed to the backrest 30 and located on the side of the backrest 30 opposite to the seat cushion 20. One end of the linkage assembly 12 is rotatably connected to the fixed base 11, and the other end is rotatably connected to the table 13. In this way, the fixed base 11, the linkage assembly 12, and the table 13 can form a four-bar linkage mechanism, enabling the table assembly 10 to... Figure 1 The folding state shown and Figure 2 , Figure 3 The movement occurs between the unfolded states shown.
[0047] Based on this, please refer to the following: Figure 2 and Figure 4 , Figure 4 for Figure 2 The diagram shows the structure of the seat 100 when the backrest 30 is in the adjusted state. The backrest 30 is rotatably connected to the seat cushion 20, so that the backrest 30 can be adjusted relative to the seat cushion 20. Figure 2 The initial state shown and Figure 4 The adjustable states shown are designed to improve user comfort. Figures 1-4 When the seat 100 shown is in the unfolded state, the angle between the table assembly 10 and the backrest 30 is fixed. Specifically, when the vehicle is on a horizontal plane and the backrest 30 is in its initial state, the angle between the backrest 30 and the horizontal plane is approximately 65°. At this time, when the table assembly 10 is in the unfolded state, the bearing surface 13a of the table 13 is approximately parallel to the horizontal plane. However, when the backrest 30 is in the adjusted state, the angle between the backrest 30 and the horizontal plane can reach approximately 58°. At this time, when the table assembly 10 is in the unfolded state, the bearing surface 13a of the table 13 is tilted relative to the horizontal plane, making it easy for items on the table 13 to slip off.
[0048] To address this issue, this application provides a table assembly 10, a seat 100, and a vehicle 1000. The table assembly 10 has an adjustment structure 14, which allows for adjustment of the angle between the bearing surface 13a of the table 13 and the horizontal plane when the table assembly 10 is in the unfolded state. The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.
[0049] Please see Figure 5 , Figure 5This is a structural schematic diagram of a vehicle 1000 provided in some embodiments of this application. This application provides a vehicle 1000, which includes a body 200, seats 100, and doors 300. The body has a driver's cabin 200a. There can be multiple doors 300, which are rotatably connected to the body 200. When the doors 300 are open, users can enter and exit the driver's cabin 200a. When the doors 300 are closed, they protect the driver's cabin 200a to ensure the safety of the user's person and property. There can be multiple seats 100, which are disposed within the driver's cabin 200a. Specifically, the seat cushion 20 of the seat 100 is fixed to the floor of the driver's cabin 200a.
[0050] Please refer to the following: Figures 6-9 , Figure 6 for Figure 5 A schematic diagram of one structure of the table assembly 10 of the seat 100 in the vehicle 100 shown. Figure 7 for Figure 6 A partial structural schematic diagram of the tabletop assembly 10 shown. Figure 8 for Figure 6 The diagram shows the principle of the tabletop assembly 10 in its unfolded and folded states. Figure 9 for Figure 6 The diagram shows the adjustment principle of the tabletop assembly 10. The tabletop assembly 10 includes a fixed base 11, a connecting rod assembly 12, a tabletop 13, and an adjustment structure 14. The fixed base 11 can be fixed to the backrest 30 by means of threaded connection, snap-fit, etc. The fixed base 11 has a first surface area 11a. Specifically, the first surface area 11a can be a planar area, and the backrest 30 can be located on the side opposite to the first surface area 11a or on the side facing the first surface area 11a.
[0051] The tabletop 13 has a bearing surface 13a, which can be a plane. One end of the connecting rod assembly 12 is rotatably connected to the tabletop 13. The adjustment structure 14 is connected to the other end of the connecting rod assembly 12 and the tabletop 13, so that the tabletop assembly 10 can move between an unfolded state and a folded state. Based on this, the adjustment structure 14 can adjust the angle between the bearing surface 13a of the tabletop 13 and the first surface area 11a when the tabletop assembly 10 is in the unfolded state.
[0052] In this way, the tabletop assembly 10 provided in this application, by rotatably connecting one end of the connecting rod assembly 12 to the fixed base 11, and connecting the adjusting structure 14 to the other end of the connecting rod assembly 12 and the tabletop 13, allows the tabletop assembly 10 to move between an unfolded state and a folded state. Thus, the user can unfold the tabletop assembly 10 to place items on the bearing surface 13a of the tabletop 13, and can also fold the tabletop assembly 10 to increase the activity space (e.g., ...). Figure 8(As shown).
[0053] Based on this, by enabling the adjustment structure 14 to adjust the angle between the bearing surface 13a of the tabletop 13 and the first surface area 11a, when the backrest 30 of the seat 100 rotates relative to the cushion 20, causing a change in the angle between the first surface area 11a and the horizontal plane, the adjustment structure 14 can adjust the angle between the bearing surface 13a and the horizontal plane, thereby ensuring that the bearing surface 13a is in a roughly horizontal state to prevent items from falling and improve the user experience (e.g., Figure 9 (As shown).
[0054] Please continue to refer to this as well. Figures 10-12 , Figure 10 for Figure 7 Enlarged view of point A in the middle. Figure 11 for Figure 7 An exploded view of a portion of the structure of the tabletop assembly 10 shown. Figure 12 for Figure 7 The diagram shows an exploded view of a portion of the structure of the tabletop assembly 10 as viewed from another perspective. The linkage assembly 12 includes a first link 121, which has opposing first end 1211 and second end 1212. The first end 1211 is rotatably connected to the fixed base 11, and the axes of rotation of both extend along a first direction. Specifically, the first end 1211 can be hinged to the fixed base 11 via a hinge axis.
[0055] The adjustment structure 14 includes a ratchet 141, a first swing arm 142, a second swing arm 143, and a pawl 144. The ratchet 141 is fixedly connected to the second end 1212 and has multiple circumferentially arranged ratchet teeth 1411. One end of the first swing arm 142 is rotatably connected to the tabletop 13, and the other end is rotatably connected to the ratchet 141. Specifically, one end of the first swing arm 142 can be rotatably connected to the tabletop 13 via a hinge shaft. One end of the second swing arm 143 is slidably connected to the tabletop 13 along a second direction, and the other end is rotatably connected to the ratchet 141. The second direction is perpendicular to the first direction. Specifically, the second direction can be parallel to the bearing surface 13a. Based on this, the pawl 144 is rotatably connected to the tabletop 13. The pawl 144 can engage between two adjacent ratchet teeth 1411 to restrict the rotation of the ratchet 141 relative to the tabletop 13, thereby restricting the tabletop 13 from continuing to rotate in the unfolding direction relative to the fixed seat 11, and can also disengage from the ratchet 141.
[0056] In this way, by rotatably connecting one end of the first swing arm 142 to the tabletop 13 and slidably connecting one end of the second swing arm 143 to the tabletop 13, and by rotatably connecting the other ends of the first swing arm 142 and the second swing arm 143 to the second end 1212 of the first connecting rod 121 via ratchet 141, the pawl 144 rotatably connected to the tabletop 13 can disengage from the ratchet 141, allowing the tabletop assembly 10 to move between the unfolded and folded states. During the movement, the distance between the second end 1212 of the first connecting rod 121 and the bearing surface 13a and the suspended end of the tabletop 13 is always changing. The pawl 144 rotatably connected to the tabletop 13 can engage between two adjacent ratchet teeth 1411, so that when the tabletop assembly 10 moves from the folded state to the unfolded state, the tabletop 13 can stop at any position where the bearing surface 13a and the first surface area 11a form an angle. Based on this, when the angle between the first surface region 11a and the horizontal plane changes, the distance between the second end 1212 and the bearing surface 13a of the table 13 and the suspended end can be adjusted by adjusting the structure 14, so that the bearing surface 13a is approximately parallel to the horizontal plane to prevent items on the bearing surface 13a from falling.
[0057] Based on this, the triangular structure formed by the first swing arm 142, the second swing arm 143, and the tabletop 13 results in high structural strength for the tabletop assembly 10. This prevents deformation and failure when heavy objects are placed on the tabletop 13, ensuring the reliability and stability of the tabletop assembly 10. Furthermore, the ratchet 141 and pawl 144 work together to lock the tabletop assembly 10 in one direction during unfolding, without affecting its movement from the unfolded to the folded state, thus simplifying its operation.
[0058] Please continue reading. Figures 10-12 The other end of the first swing arm 142 has a first through hole 142a. Specifically, the axis of the first through hole 142a extends along a first direction. The end face of the other end of the first swing arm 142 has a first opening 142b communicating with the first through hole 142a. Based on this, a ratchet 141 is disposed in the first through hole 142a, the first opening 142b exposes a portion of the ratchet teeth 1411, and a portion of the pawl 144 can pass through the first opening 142b and engage between the two ratchet teeth 1411. In this case, the first end 1211 is located on one side of the other end of the first swing arm 142 and faces one end face of the ratchet 141.
[0059] This reduces the size of the adjustment structure 14 along the first direction, making the adjustment structure 14 more compact overall, and also reduces the overall weight of the table assembly 10.
[0060] Please continue reading. Figures 10-12The adjusting structure 14 also includes a first rotating shaft 145, which is connected to one end face of the ratchet 141. Specifically, the first rotating shaft 145 can be integrally formed with the ratchet 141, or it can be fixed to the end face of the ratchet 141 by means of snap-fit, welding, threaded connection, etc. Based on this, the first rotating shaft 145 is also connected to the second end 1212 of the first connecting rod 121, that is, the second end 1212 is fixedly connected to the ratchet 141 through the first rotating shaft 145. Specifically, the end face of the first rotating shaft 145 away from the ratchet 141 has a first threaded hole 145a, and the second end 1212 has a second threaded hole 121a. A screw 146 passes through the second threaded hole 121a and the first threaded hole 145a in sequence and is threaded into both, so as to realize the fixed connection between the first rotating shaft 145 and the second end 1212.
[0061] Based on this, one end of the second swing arm 143 is sleeved on the first rotating shaft 145 and located between the second end 1212 and the first swing arm 142, so as to realize the rotational connection between the second swing arm 143 and the first rotating shaft 145, that is, the second swing arm 143 is rotatably connected to the ratchet 141 through the first rotating shaft 145.
[0062] In this way, while the first connecting rod 121 is fixedly connected to the ratchet 141 through the first rotating shaft 145, it can also prevent the second swing arm 143 from disengaging from the first rotating shaft 145, thus making the adjustment structure 14 more compact, simple in structure and more reliable.
[0063] In some other embodiments, the second end 1212 may also be directly fixed to the end face of the ratchet 141, the first rotating shaft 145 is fixed to the surface of the second end 1212 away from the ratchet 141, and the second swing arm 143 is sleeved on the first rotating shaft 145, that is, the second swing arm 143 is rotatably connected to the ratchet 141 through the first rotating shaft 145 and the second end 1212. In this case, a limiting member is connected to the first rotating shaft 145 to prevent the second swing arm 143 from falling off the first rotating shaft 145.
[0064] Please continue reading. Figures 10-12 The adjustment structure 14 also includes a limiting member 147, which is located on the side of the second end 1212 of the first swing arm 142 away from the first connecting rod 121 and connected to the other end face of the ratchet 141. A portion of the limiting member 147 is located on the outer periphery of the first through hole 142a. In this way, the limiting member 147 can cooperate with the second swing arm 143 and the first connecting rod 121 to prevent the ratchet 141 from falling off the first swing arm 142, thereby ensuring the reliability of the connection and movement of the table assembly 10.
[0065] Specifically, the limiting member 147 can be in the shape of a flange with a diameter larger than that of the ratchet 141, and the limiting member 147 and the ratchet 141 are integrally formed. In this way, the structure formed by the limiting member 147 and the ratchet 141 has high strength. At the same time, when the ratchet 141 moves relative to the first swing arm 142, the contact area between the limiting member 147 and the first swing arm 142 can be large, ensuring the reliability of limiting the ratchet 141. In some other embodiments, the limiting member 147 can also be a limiting protrusion extending from the ratchet 141 towards the outer periphery of the first through hole 142a.
[0066] Please refer to the following: Figure 6 , Figure 10 and Figure 13 , Figure 13 for Figure 6 The diagram shows a partial structural schematic of the tabletop 13 of the tabletop assembly 10. The tabletop 13 includes a tabletop body 131, a cover 132, and a sliding support 133. A bearing surface 13a is formed on the tabletop body 131. The cover 132 is located on the side opposite to the bearing surface 13a and is connected to the tabletop body 131. The cover 132 and the tabletop body 131 enclose a receiving cavity 13b, and a portion of the adjusting structure 14 can be located within the receiving cavity 13b. Specifically, the cover 132 can be connected to the tabletop body 131 by snap-fit, adhesive, threaded connection, etc. The tabletop 13 has a second opening 13c communicating with the receiving cavity 13b. The connecting rod assembly 12 passes through the second opening 13c and is connected to the adjusting structure 14. Figure 6 , Figure 10 and Figure 13 In the illustrated embodiment, a portion of the second opening 13c is located on the tabletop body 131, and another portion is located on the cover 132. In other embodiments, the second opening 13c may also be entirely located on the tabletop body 131, depending on the shape of the tabletop body 131 and the cover 132.
[0067] Based on this, the sliding support 133 is located on the side opposite to the bearing surface 13a and is fixed to the table body 131. The sliding support 133 has a groove 133a extending in the second direction. Specifically, the sliding support 133 can be fixed to the table body 131 by welding, snap-fitting, threaded connection, or other methods.
[0068] Based on this, please refer to the following: Figure 12 and Figure 13 The adjustment structure 14 also includes a slide rod 148, which is connected to the end of the second swing arm 143 away from the ratchet 141. The slide rod 148 is accommodated in the slide groove 133a and can slide and rotate relative to the sliding support 133. Specifically, the slide rod 148 can be connected to the second swing arm 143 by means of snap-fit, bonding, threaded connection, welding, etc., or it can be integrally formed with the second swing arm 143. Figure 6 , Figure 12 and Figure 13 In the illustrated embodiment, there are two sliding supports 133, located on both sides of the second swing arm 143; there are also two sliding rods 148, which are respectively accommodated in two sliding grooves 133a. In some other embodiments, there may be only one sliding support 133 and one sliding rod 148.
[0069] In this way, by fitting the slide bar 148 into the slide groove 133a and allowing it to rotate and slide relative to the sliding support 133, it is possible to ensure that the components of the table assembly 10 do not interfere with or get stuck during the movement of the table assembly 10 in the unfolded and folded states, thereby ensuring the connection reliability and movement reliability of the table assembly 10.
[0070] Please continue reading. Figures 10-12 The adjustment structure 14 also includes a second rotating shaft 149 and a handle 150. The second rotating shaft 149 includes a first shaft segment 1491, a second shaft segment 1492, and a third shaft segment 1493 connected in sequence. The first shaft segment 1491 and the third shaft segment 1493 are parallel. The end of the first shaft segment 1491 away from the third shaft segment 1493 is connected to a pawl 144. The third shaft segment 1493 is rotatably connected to the tabletop 13, that is, the pawl 144 is rotatably connected to the tabletop 13 through the second rotating shaft 149. Specifically, the tabletop 13 also includes a rotating support 134, which can be located within the receiving cavity 13b and can be fixed to the tabletop body 131 by means of adhesive, snap-fit, threaded connection, etc. The third shaft segment 1493 passes through the rotating support 134 and can rotate relative to the rotating support 134. Figures 10-12 In the illustrated embodiment, the second shaft segment 1492 is perpendicular to the first shaft segment 1491 and the third shaft segment 1493. In some other embodiments, the second shaft segment 1492 may not be perpendicular to the first shaft segment 1491 and the third shaft segment 1493.
[0071] Based on this, the handle 150 is connected to the end of the third shaft segment 1493 that is away from the first shaft segment 1491, and at least a portion of the handle 150 is located on the outer periphery of the tabletop 13. Specifically, the handle 150 can be connected to the third shaft segment 1493 by means of snap-fit, threaded connection, etc., and the handle 150 can also be integrally formed with the third shaft segment 1493. Figures 10-12 In the illustrated embodiment, the entire handle 150 is located on the outer periphery of the tabletop 13. In other embodiments, the second pivot 149 may also be movable relative to the pivot support 134 in a first direction, allowing the entire handle 150 to be located on the outer periphery of the tabletop 13 for user operation by pulling it outwards from the tabletop 13.
[0072] In this way, the user can rotate the handle 150 to disengage the pawl 144 from the ratchet 141 via the second pivot 149, thereby allowing the tabletop assembly 10 to move freely. Rotating the handle 150 also allows the pawl 144 to engage with the ratchet teeth 1411 of the ratchet 141 via the second pivot 149, keeping the tabletop 13 in a position where the bearing surface 13a is approximately parallel to the horizontal plane. Furthermore, the shape of the second pivot 149 provides clearance for the first swing arm 142, the second swing arm 143, and the ratchet 141 when the second pivot 149 rotates and disengages the pawl 144 from the ratchet 141, preventing interference between components and thus preventing the tabletop assembly 10 from jamming.
[0073] Please continue reading. Figures 10-12 The adjustment structure 14 also includes an elastic element 151. One end of the elastic element 151 is fixed relative to the pawl 144, and the other end is fixed relative to the tabletop 13. The elastic element 151 is used to apply a force to the pawl 144 pointing towards the ratchet 141. Specifically, the elastic element 151 can be a torsion spring. The elastic element 151 is sleeved on the third shaft segment 1493. One end of the elastic element 151 can be fixed to the second shaft segment 1492 of the second rotating shaft 149, and the other end is fixed to the rotating support 134. In some other embodiments, one end of the elastic element 151 can also be fixed to the pawl 144, and the other end can also be fixed to the tabletop body 131. In still some other embodiments, the elastic element 151 can also be a coil spring.
[0074] In this way, by applying a force to the pawl 144 directed towards the ratchet 141 through the elastic element 151, the reliability of the lock between the pawl 144 and the ratchet 141 can be increased. This prevents the ratchet 141 from disengaging from the pawl 144 under the weight of the items placed on the tabletop 13 when the tabletop assembly 10 is in the unfolded state, thus ensuring that the bearing surface 13a remains approximately horizontal. Furthermore, the elastic element 151 ensures that the pawl 144 remains in contact with the ratchet 141 when no external force is applied to the handle 150. When adjusting the angle between the bearing surface 13a and the first surface area 11a, simply lift the end of the tabletop 13 away from the fixing seat 11 to rotate the tabletop 13 to the corresponding position in the folding direction of the tabletop assembly 10. The pawl 144 will automatically engage with the ratchet teeth 1411 without manually rotating the handle 150.
[0075] In some other embodiments, the adjustment structure 14 may not include the elastic element 151. In this case, when the pawl 144 is engaged between the ratchet teeth 1411, the second pivot 149 is pushed into the table 13 so that a part of the handle 150 is located on the outer periphery of the table 13, and the other part of the handle 150 abuts against the table 13 to prevent the pawl 144 from disengaging from the ratchet 141.
[0076] Based on the above, please refer back to the previous section. Figures 8-10The linkage assembly 12 also includes a second linkage 122. One end of the second linkage 122 is rotatably connected to the fixed base 11, and the other end is rotatably connected to the tabletop 13. Specifically, one end of the second linkage 122 can be rotatably connected to the fixed base 11 via a hinge shaft, and the rotation axes of both extend along the aforementioned first direction. The other end of the second linkage 122 can be rotatably connected to the tabletop body 131 via a hinge shaft, and the rotation axes of both extend along the aforementioned first direction. When the tabletop assembly 10 is in the unfolded state, the second linkage 122 is located on the side of the first linkage 121 facing the bearing surface 13a.
[0077] In this way, the linkage assembly 12 can improve the motion stability of the table assembly 10, thereby improving the overall reliability of the table assembly 10.
[0078] Based on the above, there are two linkage assemblies 12, arranged at intervals along the first direction. There are also two adjustment structures 14, each corresponding to one of the linkage assemblies 12. This design improves the overall strength and movement stability of the table assembly 10, thus enhancing the overall reliability of the seat 100.
[0079] Please see Figure 14 , Figure 14 A schematic diagram illustrating the adjustment principle of the tabletop assembly 10 provided in other embodiments of this application. Figure 14 The illustrated embodiments and Figure 9 The difference in the illustrated embodiment is that the adjustment structure 14 includes an adjustment support 152, which is located on the side opposite to the bearing surface 13a and fixed to the tabletop 13. Specifically, the adjustment support 152 can be fixed to the tabletop body 131 by means of snap-fit, adhesive, threaded connection, etc. Based on this, the adjustment support 152 has multiple slots 152a. When the tabletop assembly 10 is in the unfolded state, the multiple slots 152a are arranged sequentially towards the fixed base 11 in a direction away from the bearing surface 13a. Based on this, the second end 1212 of the first connecting rod 121 can be engaged in different slots 152a, so that the distance between the second end 1212 and the bearing surface 13a and the suspended end of the tabletop 13 is different, thereby adjusting the angle between the bearing surface 13a and the first surface area 11a, and further adjusting the angle between the bearing surface 13a and the horizontal plane. When it is necessary to fold the tabletop assembly 10, pull the tabletop 13 to disengage the second end 1212 of the first connecting rod 121 from the adjusting support 152, so that the tabletop assembly 10 can move from the unfolded state to the folded state.
[0080] This makes the structure of the adjustment structure 14 simpler and cheaper, thus reducing the cost of the seat 100 with the table assembly 10, which helps to reduce the overall cost of the vehicle 1000.
