[0048] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0049] like Figures 1 to 17As shown, the seat armrest 100 of this embodiment includes an armrest box 1, a table assembly 2, a first elastic member 3, and an unlocking assembly 4. The armrest box 1 has a receiving cavity 111. The table assembly 2 is movably connected to the armrest box 1 and can switch between a stored position within the receiving cavity 111 and a used position outside the receiving cavity 111. The first elastic member 3 is disposed between the armrest box 1 and the table assembly 2 and is connected to both. The first elastic member 3 provides elastic force to the table assembly 2 to move it out of the receiving cavity 111. The table assembly 2 has a first locking part 221, and the unlocking assembly 4 has a second locking part 413. The unlocking assembly 4 is movably connected to the armrest box 1 and can switch between a locked position where the second locking part 413 engages with the first locking part 221 and an unlocked position where the second locking part 413 leaves the first locking part 221. When the tabletop assembly 2 is in the folded position, the unlocking component 4 is in the locked position, so that the tabletop assembly 2 remains in the folded position. When the unlocking component 4 is in the unlocked position, the tabletop assembly 2 switches to the use position under the elastic force of the first elastic element 3.

[0050] In this embodiment of the invention, the armrest 100 allows the user to easily access the table assembly 2. When the user needs to use the table assembly 2, they simply operate the unlocking component 4, causing it to switch to the unlocked position where the second locking part 413 is disengaged from the first locking part 221. The table assembly 2 then automatically switches to a position outside the receiving cavity 111 under the elastic force of the first elastic member 3. When the table assembly 2 is not needed, it is stored within the receiving cavity 111, and the unlocking component 4 switches to the locked position where the second locking part 413 engages with the first locking part 221, thus maintaining the table assembly 2 in the stored position. Compared to related technologies that involve pulling or rotating to remove the table from the receiving cavity, this method simplifies the table removal operation and improves the ease of use.

[0051] Therefore, the seat armrest 100 of the present invention has the advantages of easy use of the table assembly 2.

[0052] In some embodiments, such as Figure 1 and Figure 2 As shown, the armrest box 1 includes a box body 11 and a support 12. The box body 11 has the aforementioned receiving cavity 111. The support 12 is disposed in the receiving cavity 111 and connected to the box body 11. The table assembly 2 and the unlocking assembly 4 are both connected to the support 12. The first elastic member 3 is disposed between the support 12 and the table assembly 2 and is connected to the support 12.

[0053] In some embodiments, in order to ensure connection reliability, the connection positions between the armrest box 1 and the table assembly 2, as well as the connection positions between the armrest box 1 and the unlocking assembly 4, need to have high structural strength.

[0054] By setting the armrest box 1 to include a box body 11 and a support 12, and connecting the table assembly 2 and the unlocking assembly 4 to the support 12, the structural strength of the support 12 can be set to be high to ensure the reliability of the connection between the armrest box 1 and the table assembly 2 and between the armrest box 1 and the unlocking assembly 4. At the same time, the structural strength of the box body 11 can be set to be low to reduce the cost of the armrest box 1.

[0055] Therefore, the overall cost of the armrest box 1 can be reduced while ensuring the reliability of the connection between the armrest box 1 and the table assembly 2, as well as between the armrest box 1 and the unlocking assembly 4. In addition, when assembling the seat armrest 100, the table assembly 2 and the unlocking assembly 4 can be connected to the bracket 12 first, and then the bracket 12 can be connected to the box 11, so as to facilitate the assembly of the seat armrest 100.

[0056] The bracket 12 is set inside the receiving cavity 111, which can prevent the bracket 12 from being exposed outside the receiving cavity 111, and helps to improve the appearance of the seat armrest 100.

[0057] Of course, in other embodiments, the armrest box 1 may only include the box body 11. By thickening the box body 11 as a whole, the reliability of the connection between the armrest box 1 and the table assembly 2 and the armrest box 1 and the unlocking assembly 4 can be ensured.

[0058] Optionally, the bracket 12 is bonded to the housing 11 or connected by fasteners. The fasteners can be clips, bolts, screws, or rivets, etc.

[0059] Optionally, such as Figures 3 to 8 As shown, the bracket 12 includes a main frame 121 and a secondary frame 122. The main frame 121 and the secondary frame 122 are fixedly connected. The table assembly 2 is connected to the main frame 121, and the unlocking assembly 4 is connected to the secondary frame 122.

[0060] Therefore, when assembling the seat armrest 100, the table assembly 2 and the unlocking assembly 4 are connected to the main frame 121 and the sub-frame 122 respectively, which can effectively avoid interference between the table assembly 2 and the unlocking assembly 4, and improve the assembly convenience and reliability of the seat armrest 100.

[0061] Optionally, the main frame 121 and the sub-frame 122 are bonded, welded, or connected by fasteners. These fasteners can be clips, bolts, screws, or rivets, etc.

[0062] Optionally, such as Figure 12 As shown, the main frame 121 includes two longitudinal beams 1212 and a crossbeam 1213 arranged at intervals. The two ends of the crossbeam 1213 are connected to the two longitudinal beams 1212 respectively. The two longitudinal beams 1212 and the crossbeam 1213 form a "gate" shaped frame.

[0063] In some embodiments, such as Figure 1 and Figure 2 As shown, the tabletop assembly 2 includes a tabletop body 21 and a connector 22. The tabletop body 21 is rotatably connected to the connector 22, and the connector 22 is rotatably connected to the armrest box 1, so that the tabletop body 21 can be swingably connected to the armrest box 1.

[0064] For example, connector 22 is a connecting rod, one end of which is hinged to the tabletop body 21 via a hinge, and the other end of which is hinged to the armrest box 1 via a hinge. The hinge can be a friction hinge, allowing the tabletop assembly 2 to slowly pop out under the frictional force of the friction hinge.

[0065] Understandably, if the tabletop body 21 is set to move along a preset direction, the tabletop assembly 2 can only be used within the movement path of the tabletop body 21. However, by swaying the tabletop body 21 to the armrest box 1, the use position of the tabletop assembly 2 can be more flexible.

[0066] Therefore, by swaying the tabletop body 21 to the armrest box 1, the usage position of the tabletop assembly 2 can be designed according to user needs, which helps to improve the user experience.

[0067] Optionally, such as Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 11 , Figure 13 and Figure 17 As shown, the first elastic element 3 is a torsion spring.

[0068] For example, a torsion spring is sleeved on the main frame 121, and the two ends of the torsion spring abut against the main frame 121 and the connector 22 respectively, so that the torsion spring provides elastic force to the connector 22 to rotate around the main frame 121.

[0069] Therefore, the first elastic element 3 occupies less space, which can reduce the space requirement of the receiving cavity 111.

[0070] Optionally, the tabletop body 21 includes a first plate 211 and a second plate 212. The first plate 211 is rotatably connected to the connector 22, and the second plate 212 is rotatably connected to the first plate 211 so that the second plate 212 can switch between a folded state folded with the first plate 211 and an unfolded state coplanar with the first plate 211.

[0071] For example, such as Figure 1 , Figure 2 , Figure 9 and Figure 12As shown, the first plate 211 and the second plate 212 are hinged together by a friction hinge 213. When the tabletop assembly 2 needs to be stored, the second plate 212 rotates to a folded state with the first plate 211, reducing the area occupied by the tabletop assembly 2 and making it easier to store the tabletop assembly 2 in the receiving cavity 111. When the tabletop assembly 2 needs to be used, the tabletop assembly 2 is first moved out of the receiving cavity 111, and then the second plate 212 rotates to an unfolded state that is coplanar with the first plate 211, increasing the usable area of ​​the tabletop body 21 for user convenience. Furthermore, when the second plate 212 rotates to the unfolded state that is coplanar with the first plate 211, the friction of the friction hinge 213 keeps the second plate 212 in the unfolded state that is coplanar with the first plate 211.

[0072] Optionally, the number of connectors 22 is three or more, with at least three connectors 22 not on the same straight line. The first elastic member 3 may provide elastic force to each connector 22, or it may provide elastic force to only a portion of the connectors 22.

[0073] For example, there are three connectors 22, and the three connectors 22 are not on the same straight line. The first elastic element 3 provides elastic force to two of the connectors 22.

[0074] By setting three or more connectors 22, and at least three connectors 22 are not on the same straight line, when the tabletop assembly 2 is in the use position, the multiple connectors 22 support at least three positions of the tabletop body 21 that are not on the same straight line, thereby improving the support stability of the connectors 22 on the tabletop body 21 and improving the reliability of the tabletop assembly 2.

[0075] Optionally, such as Figure 1 and Figure 2 As shown, the armrest box 1 has an opening 112 communicating with the receiving cavity 111. When the tabletop assembly 2 is in the storage position, the tabletop body 21 is located inside the opening 112 and blocks the opening 112. When the tabletop assembly 2 is in the use position, the tabletop body 21 is positioned biased towards the opening 112 on one side along the length direction of the armrest box 1.

[0076] When the tabletop assembly 2 is in the storage position, the tabletop body 21 is located inside the opening 112 and the opening 112 is blocked. On the one hand, this can prevent the tabletop body 21 from occupying the space of the receiving cavity 111, further reducing the space requirement of the receiving cavity 111; on the other hand, it can avoid setting a separate cover to block the opening 112, which helps to simplify the structure of the seat armrest 100.

[0077] like Figure 1 and Figure 2As shown, when the table assembly 2 is in the use position, the table body 21 is positioned biased towards the opening 112 on one side of the armrest box 1 along its length, so that the table body 21 can extend out of the armrest box 1 along its length. On the one hand, this avoids interference between the table assembly 2 in the use position and the body of the user sitting on the seat, improving the user's riding comfort; on the other hand, it ensures that when the table assembly 2 is in the use position, the table body 21 is in a position that is convenient for the user to use, further improving the user experience.

[0078] Optionally, such as Figure 12 and Figure 13 As shown, the connector 22 has a first connecting part 222 and a second connecting part 223. The table body 21 is rotatably connected to the first connecting part 222, and the second connecting part 223 is rotatably connected to the armrest box 1.

[0079] It is understandable that if the tabletop assembly 2 is in the storage position and the use position, and if the first connecting part 222 is located on the same side of the second connecting part 223 in the length direction of the armrest box 1, then when the tabletop assembly 2 is in the use position and the user applies pressure to the tabletop body 21, the tabletop assembly 2 will swing toward the storage position under the action of the pressure.

[0080] When the tabletop assembly 2 is in the storage position, the first connecting part 222 is located on one side of the second connecting part 223 in the length direction of the armrest box 1; when the tabletop assembly 2 is in the use position, the first connecting part 222 is located on the other side of the second connecting part 223 in the length direction of the armrest box 1.

[0081] To make the technical solution of this application easier to understand, the following description further illustrates the technical solution of this application, taking the example that the length direction of the armrest box 1 is consistent with the front-to-back direction.

[0082] For example, when the tabletop assembly 2 is in the folded position, the first connecting portion 222 is located behind the second connecting portion 223 in the front-back direction. When the tabletop assembly 2 is in the use position, the first connecting portion 222 is located in front of the second connecting portion 223 in the front-back direction. When the tabletop assembly 2 is in the use position and the user applies pressure to the tabletop body 21, the tabletop assembly 2 will swing forward under the pressure. To switch the tabletop assembly 2 from the use position to the folded position, the tabletop assembly 2 needs to be swung backward.

[0083] Therefore, the above design can effectively prevent the table assembly 2 from switching to the storage position when the user applies pressure to the table body 21, thereby further improving the reliability of the seat armrest 100.

[0084] Optionally, the opening 112 is located on the top wall of the armrest box 1.

[0085] It is understandable that if the opening 112 is located on the side wall of the armrest box 1, and there is a seat next to the side wall, the table assembly 2 will encroach on the user's seating space and affect the user's seating comfort when switching between the use position and the storage position.

[0086] By setting the opening 112 on the top wall of the armrest box 1, the table assembly 2 can be prevented from encroaching on the top space of the armrest box 1 when switching between the use position and the storage position, thus effectively preventing the table assembly 2 from encroaching on the user's seating space and improving the user's seating comfort.

[0087] Optionally, such as Figure 10 , Figure 11 , Figure 16 and Figure 17 As shown, the armrest box 1 has a first limiting part 1231 and a second limiting part 1232, and the table assembly 2 has a third limiting part 224. When the table assembly 2 is in the storage position, the third limiting part 224 abuts against the first limiting part 1231; when the table assembly 2 is in the use position, the third limiting part 224 abuts against the second limiting part 1232.

[0088] Therefore, when the tabletop assembly 2 is in the storage position, the third limiting part 224 abuts against the first limiting part 1231, which can stably keep the tabletop assembly 2 in the storage position; when the tabletop assembly 2 is in the use position, the third limiting part 224 abuts against the second limiting part 1232, which can stably keep the tabletop assembly 2 in the use position, further improving the reliability of the seat armrest 100.

[0089] Optionally, the armrest box 1 has a limiting groove 123, which has a first groove sidewall and a second groove sidewall disposed opposite to each other. The tabletop assembly 2 has a limiting protrusion, which is movably disposed within the limiting groove 123. When the tabletop assembly 2 is in the storage position, the limiting protrusion abuts against the first groove sidewall; when the tabletop assembly 2 is in the use position, the limiting protrusion abuts against the second groove sidewall. The first groove sidewall forms a first limiting portion 1231, the second groove sidewall forms a second limiting portion 1232, and the limiting protrusion forms a third limiting portion 224.

[0090] Therefore, the armrest box 1 and the table assembly 2 have a simple structure, which facilitates the processing and manufacturing of the seat armrest 100.

[0091] Optionally, such as Figure 10 and Figure 16 As shown, the main frame 121 has a limiting groove 123, and the connector 22 has a limiting protrusion.

[0092] By setting the limiting groove 123 on the main frame 121, the limiting groove 123 can be avoided from being exposed on the outside of the armrest box 1, further improving the appearance of the seat armrest 100. By setting the limiting protrusion on the connector 22, the structure of the table assembly 2 can be simplified, thereby simplifying the overall structure of the seat armrest 100.

[0093] Optionally, the limiting groove 123 is an arc-shaped groove, and the limiting protrusion can slidably cooperate with the limiting groove.

[0094] Therefore, when the table panel assembly 2 switches between the use position and the storage position, the limiting protrusion and the limiting groove can guide the swing of the table panel assembly 2, further improving the reliability of the seat armrest 100.

[0095] In some embodiments, the unlocking component 4 includes an unlocking member and a second elastic member 43. The unlocking member is movably connected to the armrest box 1 and has an operating part 422 for triggering the unlocking component 4 to switch from a locked position to an unlocked position. The second elastic member 43 is disposed between the unlocking component 4 and the armrest box 1 and provides elastic force to the unlocking component 4, allowing the unlocking component 4 to switch from an unlocked position to a locked position under the elastic force of the second elastic member 43.

[0096] Therefore, the user only needs to perform the corresponding operation on the operation unit 422 to switch the unlocking component 4 from the locked position to the unlocked position; and the unlocking component 4 can automatically switch from the unlocked position to the locked position under the elastic force of the second elastic member 43, thereby facilitating the switching of the unlocking component 4 between the locked position and the unlocked position, and further improving the ease of use of the table panel component 2.

[0097] Optionally, the unlocking component is movably connected to the armrest box 1 so that when the operating part 422 is pressed, the unlocking component 4 is triggered to switch from the locked position to the unlocked position.

[0098] By pressing the operating part 422, the unlocking component 4 can be triggered to switch from the locked position to the unlocked position, further improving the ease of use of the tabletop component 2.

[0099] Optionally, the first locking part 221 is provided on the connector 22.

[0100] For example, such as Figure 13 As shown, one of the connectors 22 is provided with a locking protrusion, and the first locking part 221 is provided on the locking protrusion.

[0101] Optionally, the aforementioned limiting protrusion and the aforementioned locking protrusion are respectively provided on two different connectors 22.

[0102] For example, there are three connectors 22. The first connector 22 has the aforementioned limiting protrusion, the second connector 22 has the aforementioned locking protrusion, and the third connector 22 has neither a limiting protrusion nor a locking protrusion.

[0103] Optionally, the unlocking component includes a locking member 41 and a pushing member 42. The locking member 41 has the aforementioned second locking portion 413. The locking member 41 is movably connected to the armrest box 1, and the pushing member 42 is movably connected to the armrest box 1. A second elastic member 43 is disposed between the locking member 41 and the armrest box 1, and the second elastic member 43 is used to provide elastic force to the locking member 41 toward the first locking portion 221. The pushing member 42 has a pushing portion 4211 and an operating portion 422, and the pushing portion 4211 abuts against the locking member 41. When the table assembly 2 is in the stowed position, the second elastic member 43 pushes the locking member 41 to move, so that the unlocking component 4 switches to the locked position. When the operating portion 422 is pressed, the pushing portion 4211 pushes the locking member 41 to move, so that the unlocking component 4 switches to the unlocked position.

[0104] By setting the unlocking component to include a locking component 41 and a pushing component 42, the structures of the locking component 41 and the pushing component 42 are relatively simple. On the one hand, this facilitates the mass production of the locking component 41 and the pushing component 42, which helps to reduce the cost of the unlocking component and thus the cost of the seat armrest 100. On the other hand, it facilitates adaptive design based on the functions of the locking component 41 and the pushing component 42.

[0105] Of course, in other embodiments, the unlocking component can also be an integral structure, that is, the locking component 41 and the pushing component 42 are integrally formed.

[0106] Optionally, one of the first locking portion 221 and the second locking portion 413 is a locking protrusion, and the other of the first locking portion 221 and the second locking portion 413 is a locking groove.

[0107] For example, such as Figure 13 and Figure 14 As shown, the second locking part 413 is a locking protrusion, and the first locking part 221 is a locking groove, and the locking groove is provided on the connector 22.

[0108] Therefore, when the unlocking component 4 is in the locked position, the locking protrusion is located in the locking groove, and the locking protrusion abuts against the side wall of the locking groove, so that the locking protrusion and the locking groove are locked together; when the unlocking component 4 is in the unlocked position, the locking protrusion disengages from the locking groove, releasing the limiting effect of the locking protrusion on the locking groove. By setting one of the first locking part 221 and the second locking part 413 as a locking protrusion and the other of the first locking part 221 and the second locking part 413 as a locking groove, the structure of the first locking part 221 and the second locking part 413 is simple, which facilitates the processing and manufacturing of the locking part 41 and the table assembly 2.

[0109] Optionally, at least one of the locking protrusion and the locking groove is provided with a guide bevel.

[0110] For example, the locking protrusion is provided with a guide slope. When the unlocking component 4 switches between the locked position and the unlocked position, the locking protrusion enters or leaves the locking groove under the guidance of the guide slope.

[0111] Optionally, the sidewall of the locking groove has a notch so that the locking protrusion can enter or exit the locking groove through the notch.

[0112] Optionally, the armrest box 1 has a first guide portion 1221, and the locking member 41 has a second guide portion 411, which is movably guided and engaged with the first guide portion 1221.

[0113] For example, such as Figure 5 and Figure 8 As shown, the subframe 122 has a guide rail, and the locking member 41 has a guide block, which is movably engaged with the guide rail. The guide rail forms the first guide portion 1221, and the guide block forms the second guide portion 411.

[0114] Therefore, when the locking member 41 moves relative to the armrest box 1, the second guide part 411 and the first guide part 1221 cooperate to guide the movement of the locking member 41, preventing the locking member 41 from deviating from the preset path, thereby further improving the reliability of the seat armrest 100.

[0115] Optionally, the armrest box 1 has a third guide portion 1211, and the pusher 42 has a fourth guide portion 4212, which is movably guided and engaged with the third guide portion 1211.

[0116] For example, such as Figure 13 As shown, the main frame 121 has a guide hole, and the pusher 42 has a guide post, which is movably guided and engaged with the guide hole. The guide hole forms the third guide portion 1211, and the guide post forms the fourth guide portion 4212.

[0117] Therefore, when the pusher 42 moves relative to the armrest box 1, the fourth guide part 4212 and the third guide part 1211 cooperate to guide the movement of the pusher 42, preventing the pusher 42 from deviating from the preset path, thereby further improving the reliability of the seat armrest 100.

[0118] Optionally, the guide post is formed from a portion of the pusher 42.

[0119] Optionally, such as Figure 1 and Figure 2 As shown, the armrest box 1 has a clearance opening 113 that communicates with the receiving cavity 111, the locking member 41 is provided in the receiving cavity 111, and the operating part 422 is provided corresponding to the clearance opening 113.

[0120] By placing the locking element 41 inside the receiving cavity 111, the locking element 41 can be exposed outside the receiving cavity 111, further improving the aesthetic appearance of the seat armrest 100.

[0121] Optionally, the clearance 113 is provided on the side wall of the armrest box 1.

[0122] Understandably, if the clearance 113 is located on the top wall of the armrest box 1, users may accidentally bump the operating part 422 when placing heavy objects on top of the armrest box 1, causing the table assembly 2 to switch from the storage position to the use position, resulting in a poor user experience. By placing the clearance 113 on the side wall of the armrest box 1, accidental bumping of the operating part 422 can be effectively avoided, thus improving the user experience.

[0123] Optionally, such as Figure 3 and Figure 6 As shown, the pusher 42 includes a rod 421 and an operation button. The operation button is located at one end of the rod 421, the other end of the rod 421 forms a pusher part 4211, and the operation button forms an operation part 422.

[0124] By using the operation button as the operation unit 422, it is convenient for users to press the operation unit 422, further improving the user experience.

[0125] Optionally, the operation button is detachably connected to the lever 421.

[0126] For example, the operating button is connected to the lever 421 by a threaded fastener, which may be a screw.

[0127] Optionally, such as Figure 14As shown, the rod 421 includes a first rod segment 4213 and a second rod segment 4214 arranged sequentially, with the extension direction of the first rod segment 4213 intersecting the extension direction of the second rod segment 4214. The end of the first rod segment 4213 away from the second rod segment 4214 forms an operating part 422, and the end of the second rod segment 4214 away from the first rod segment 4213 forms a pushing part 4211.

[0128] For example, such as Figure 14 As shown, the extension direction of the first segment 4213 is perpendicular to the extension direction of the second segment 4214.

[0129] By designing the lever 421 as described above, the relative position between the operating part 422 and the pushing part 4211 can be set more flexibly. For example, the operating part 422 can be set in a position that is convenient for the user to operate, thereby further improving the user's ease of use.

[0130] Optionally, the first segment 4213 and the second segment 4214 are integrally formed.

[0131] Optionally, such as Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 14 As shown, the second elastic element 43 is a compression spring. The armrest box 1 has a first positioning post 1222, and the unlocking assembly 4 has a second positioning post 412. The first positioning post 1222 and the second positioning post 412 are arranged opposite to each other along the moving direction of the unlocking assembly 4. One end of the compression spring is sleeved on the first positioning post 1222, and the other end of the compression spring is sleeved on the second positioning post 412.

[0132] For example, the subframe 122 has a first positioning post 1222.

[0133] Therefore, when installing the second elastic member 43, both ends of the second elastic member 43 can be respectively fitted onto the first positioning post 1222 and the second positioning post 412 to achieve positioning of the second elastic member 43, thereby facilitating the installation of the second elastic member 43, which in turn facilitates the assembly of the seat armrest 100, helps to improve the assembly efficiency of the seat armrest 100, and reduces the cost of the seat armrest 100.

[0134] How to use the seat armrest 100 according to an embodiment of the present invention:

[0135] like Figure 1As shown, firstly, the user presses the operating part 422 of the pusher 42, which drives the locking part 41 to move, and the unlocking component 4 switches to the unlocking position where the second locking part 413 leaves the first locking part 221; then, the tabletop assembly 2 swings from the storage position to the use position under the elastic force of the first elastic member 3, at which time the tabletop body 21 is in a position convenient for the user to use; then, the second plate 212 is manually flipped so that the second plate 212 is coplanar with the first plate 211.

[0136] like Figure 2 As shown, firstly, the second plate 212 is manually flipped over, causing the second plate 212 to fold with the first plate 211; then, the table assembly 2 is manually moved and swung into the receiving cavity 111, causing the table assembly 2 to switch from the use position to the storage position; then, under the elastic force of the second elastic member 43, the unlocking component 4 switches to the locking position where the second locking part 413 and the first locking part 221 lock together, so that the table assembly 2 remains in the storage position.

[0137] The seat armrest 100 of this embodiment of the invention has the following advantages:

[0138] The tabletop assembly 2 is integrated into the armrest box 1. The space of the receiving cavity 111 of the armrest box 1 serves as the storage space for the tabletop assembly 2, eliminating the need for additional storage space for the tabletop assembly 2.

[0139] The tabletop assembly 2 can be opened in just two steps, reducing the number of steps required to operate the tabletop assembly 2. These two steps are pressing the operating part 422 and flipping the second plate 212.

[0140] The tabletop assembly 2 can share the same frame as the armrest box 1, which has significant cost and weight advantages. For example, the tabletop assembly 2 shares the same support 12 as the box body 11.

[0141] The table assembly 2 is integrated into the seat armrest 100, so its use is not affected by the position of the front seats.

[0142] The seat in this embodiment of the invention includes a seat body and a seat armrest 100. The seat armrest 100 is disposed on one side of the seat body, and the seat armrest 100 is the seat armrest 100 described in any of the above embodiments.

[0143] The seat in this embodiment of the invention has advantages such as ease of use.

[0144] The vehicle of this invention includes the seat described in any of the above embodiments.

[0145] Optionally, the vehicle has two rows of seats, one in the front and one in the rear. The rear seats employ the seating configuration described in any of the above embodiments, enabling them to function as small tables. This enhances the cabin configuration without compromising passenger space, providing users with a convenient, reliable, and aesthetically pleasing table.

[0146] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Any changes, modifications, substitutions and variations made to the above embodiments by those skilled in the art are within the protection scope of the present invention.
