Description

Technical Field

[0001] This utility model relates to the field of vehicle seating technology, and in particular to a seat table assembly and a seat. Background Technology

[0002] Small tray tables are typically installed on the back of seats in various modes of transportation. When unfolded, these tray tables provide passengers with a place to put their belongings or water cups, while folding them up provides more space. Traditionally, these tray tables usually have recessed areas in the corners for placing water cups, but when passengers need more space to fold up the tray tables, there may be nowhere to put their water cups.

[0003] In response, the prior art provides a novel structure with two usable surfaces on the table. One usable surface has a cup holder, and the other usable surface has a cup rack. When the table is unfolded, the cup is placed on the cup holder. When the table is folded up, the cup rack can be used to place the cup, thus taking into account both the passenger's need for space and the need to place the cup.

[0004] The existing technology still has shortcomings. When passengers need to fold up the table, if there is a water cup on the table, they need to remove the water cup from the table first, fold up the table, and then put the water cup back on the cup holder. This makes it impossible to complete the operation with one hand, resulting in a poor user experience. Utility Model Content

[0005] The purpose of this utility model is to provide a seat table assembly and a seat, so that when passengers need to fold up the table, they do not need to pick up and put down their water cups again, and can complete the operation with one hand, thus improving the user experience.

[0035] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0036] like Figures 1-8As shown, this utility model provides a seat table assembly, including a clearance component, a table assembly, and a cup holder assembly. The clearance component is connected to the seat back and is angled relative to the seat back. The clearance component has a first limiting part 11. The table assembly includes a table body 4, which is rotatable relative to the clearance component. The table assembly has a second limiting part 31, which engages with the first limiting part 11 to restrict the rotation of the table body 4 relative to the clearance component and keep the table body 4 horizontal, thereby meeting the needs of passengers placing items. The cup holder assembly supports a water cup and is rotatably connected to the clearance component. The cup holder assembly has a third limiting part 51, which engages with the first limiting part 11 to restrict the rotation of the cup holder assembly relative to the clearance component and keep the cup holder assembly horizontal, thereby meeting the needs of passengers placing water cups and preventing the water cups from tipping over. In this embodiment, the seat and table assembly has a first limiting part 11 in the avoidance component and a second limiting part 31 in the table assembly that fits with the first limiting part 11 to keep the table body 4 horizontal. At the same time, a cup holder assembly is provided, and a third limiting part 51 in the cup holder assembly fits with the first limiting part 11 to keep the cup holder assembly horizontal. This satisfies the storage needs of the table body 4 and the cup holder assembly's need to support water cups. The table assembly and cup holder assembly can rotate independently relative to the avoidance component without affecting each other. When the table assembly is folded up, the cup holder assembly is not affected. There is no need to pick up or put down water cups, and the operation can be completed with one hand, improving the user experience.

[0037] Furthermore, the cup holder assembly and tabletop assembly can be of two types. The first type involves the cup holder assembly and tabletop assembly being connected to the clearance assembly along the width direction of the seat back, with the cup holder assembly located on one side of the seat back's width and the tabletop assembly on the other side. Each component occupies a portion of the space behind the seat back, preventing interference during movement. Alternatively, the width of the tabletop assembly can be set to be equal to the width of the seat back, with space reserved on the tabletop body 4 for the cup holder assembly to move. This ensures no interference during movement while also increasing the area of ​​the tabletop body 4, allowing for the placement of more items. In this embodiment, the cup holder assembly and tabletop assembly are arranged using the latter method. Specifically, the tabletop body 4 is provided with a receiving groove 41 for accommodating the cup holder assembly. When the second limiting part 31 of the tabletop assembly is in contact with the first limiting part 11 of the avoidance assembly, the tabletop body 4 remains horizontal. At this time, the cup holder assembly is rotated so that the third limiting part 51 of the cup holder assembly is also in contact with the first limiting part 11. The cup holder assembly remains horizontal and is located in the receiving groove 41 of the tabletop body 4, that is, both the tabletop assembly and the cup holder assembly are unfolded. See the following for details. Figure 1As shown. When the tabletop assembly needs to be folded up, the tabletop assembly is rotated in the reverse direction to disengage the second limiting part 31 from the first limiting part 11. During this process, due to the arrangement of the receiving groove 41, the cup holder assembly does not rotate, thus achieving the simultaneous folding up of the tabletop assembly and unfolding of the cup holder assembly. See the attached diagram for details. Figure 2 As shown. When it is necessary to retract the cup holder assembly, rotate the cup holder assembly in the reverse direction to disengage the third limiting part 51 from the first limiting part 11, allowing the cup holder assembly to re-enter the receiving groove 41. That is, both the tabletop assembly and the cup holder assembly are retracted. See the following for details. Figures 3-4 As shown. The tabletop assembly can be locked in place using a locking structure found in the prior art, which will not be elaborated upon here. The cup holder assembly can maintain its retracted position by using a damping structure found in the prior art at the pivot point, or by using a snap-fit ​​structure found in the prior art to snap onto the inner wall of the receiving groove 41. These structures are conventional in the art and will not be elaborated upon here.

[0038] Specifically, the avoidance assembly includes a pivot 2, two rocker arms 1, and two positioning blocks 7. The two positioning blocks 7 are fixedly connected to both sides of the seat back. Correspondingly, the two rocker arms 1 are rotatably connected to both sides of the seat back, and both ends of the pivot 2 are connected to the two rocker arms 1. The cup holder assembly and the table assembly are both rotatably connected to the pivot 2. A first limiting part 11 is provided on the rocker arm 1. The positioning blocks 7 are used to limit the angle of rotation of the rocker arm 1 relative to the seat back. After the rocker arm 1 rotates a certain angle relative to the seat back, it abuts against the positioning block 7 under the action of gravity and maintains that angle. Correspondingly, the table assembly and cup holder assembly can have a gap between themselves and the seat back, avoiding affecting the angle adjustment of the seat back. The first limiting part 11, the second limiting part 31, and the third limiting part 51 are all provided with flat surfaces. When the rocker arm 1 abuts against the positioning block 7, the flat surface of the first limiting part 11 is in a horizontal state. After the flat surface of the second limiting part 31 is in contact with the flat surface of the first limiting part 11, the table assembly cannot continue to rotate and remains in a horizontal state. Similarly, after the plane of the third limiting part 51 is in contact with the plane of the first limiting part 11, the cup holder assembly cannot continue to rotate and remains in a horizontal state.

[0039] Furthermore, such as Figures 7-8As shown, the cup holder assembly includes a bracket 5 and a cup holder 6. The cup holder 6 is hinged to the bracket 5 and supports the cup. The bracket 5 is rotatably connected to the pivot 2 of the avoidance assembly, and the bracket 5 is provided with a third limiting part 51. One of the bracket 5 and the cup holder 6 is provided with a hinge shaft 53, and the other is provided with a hinge hole 61. The hinge shaft 53 and the hinge hole 61 cooperate, and the hinge axis is parallel to the axis of the pivot 2, so that the cup holder 6 can rotate relative to the bracket 5 around the hinge shaft 53. When placing a cup, if the seat back is reclined at a large angle, the cup holder 6 can be rotated a certain angle relative to the bracket 5 first. After placing the cup, the cup holder 6 rotates in the opposite direction relative to the bracket 5 under its own weight and the weight of the cup, and finally reaches a horizontal state. Similarly, when taking out the cup, the cup holder 6 can also be rotated relative to the bracket 5 before taking it out. Optionally, the structure of the cup holder 6 varies depending on the structure of the cup. For example, the cup holder 6 can be a ring structure or a cylindrical structure. The ring-shaped cup holder 6 is suitable for disposable paper cups and other water cups, supporting the flange at the cup rim. The cup body is located below the cup holder 6, reducing the space occupied above and avoiding interference with the seat back. The cylindrical cup holder 6 is suitable for cylindrical water cups such as insulated cups and glass cups. The cylindrical cup holder 6 is hinged to the bracket 5 at the upper opening, and the main body is located below the bracket 5, which also allows the water cup to be lowered to a certain extent, reducing the space occupied above and avoiding interference with the seat back.

[0040] Alternatively, please continue to refer to Figures 7-8As shown, a guide part 54 is also provided on the bracket 5, located directly below the junction of the bracket 5 and the cup holder 6. The guide part 54 has a support part, and the wall surface of the support wall 541 is flat, with the cup holder 6 fitting against the support wall 541. The lower surface of the cup holder 6 is also flat. When the third limiting part 51 fits against the first limiting part 11, the wall surface of the support wall 541 is horizontal, and the lower surface of the cup holder 6 fits against the wall surface of the support wall 541, which helps to keep the cup holder 6 horizontal. In addition, when there is acceleration or deceleration, forward or backward tilting, or bumps, the lower surface of the cup holder 6 fitting against the wall surface of the support wall 541 can, to a certain extent, prevent the cup holder 6 from rotating significantly and prevent the cup from tipping over. In this embodiment, the width of the support wall 541 is smaller than the width of the hinge shaft 53, so that when the passenger needs to rotate the cup holder 6, a slight force is required to rotate the cup holder 6 relative to the cup holder, that is, the lower surface of the cup holder 6 disengages from the wall surface of the support wall 541. Furthermore, the guide part 54 also has two guide walls 542, located on both sides of the support wall 541 along its width direction. The walls of the guide walls 542 are convex arc surfaces. Due to the large amplitude of acceleration, deceleration, forward / backward tilting, or bumping, when the cup holder 6 rotates and disengages from the support wall 541, it is supported by the guide walls 542. Because the walls of the guide walls 542 are convex arc surfaces, the cup holder 6, under its own weight (i.e., the weight of the cup), has a rotational torque opposite to the direction of rotation, causing the cup holder 6 to rotate in the opposite direction until it returns to a horizontal position. During this process, the rotational torque of the cup holder 6 decreases with the reverse rotation until it becomes zero after re-engaging with the guide walls 542. The guide wall 542 is designed so that the cup holder 6 can quickly return to a horizontal state after rotation.

[0041] Furthermore, such as Figures 5-6 As shown, the table assembly includes a table body 4 and a swing arm 3. The table body 4 is used to place items, and the swing arm 3 is used to connect the table body 4 to the pivot 2 of the avoidance component. The swing arm 3 is rotatably connected to the avoidance component, and a second limiting part 31 is provided on the swing arm 3. The table body 4 and the swing arm 3 are slidably connected, and the table body 4 can slide in a direction close to or away from the seat back. There are various ways to achieve a slidable connection between the table body 4 and the swing arm 3, such as achieving a slidable connection through a hole-shaft engagement, or achieving a slidable connection through a dovetail-structured slide rail. In this embodiment, the table body 4 and the swing arm 3 are slidably connected through a hole-shaft engagement. The swing arm 3 is also provided with a guide rod 32, and the table body 4 is correspondingly provided with a guide hole. The table body 4 is slidably connected to the guide rod 32 through the guide hole.

[0042] This utility model provides a seat, including the seat table assembly in this embodiment, which improves the user experience.
