Example 1:

[0042] like Figures 1 to 10 An armrest with a foldable table top is shown, comprising:

[0043] A handrail frame 1, wherein at least one assembly through hole 2 is constructed in the handrail frame 1, and at least one vertical beam 3 is longitudinally arranged in at least one of the assembly through holes 2;

[0044] Hinge 4, connected between the vertical beam 3 and the table top 5, so that the table top 5 can be flipped relative to the vertical beam 3;

[0045] The table top 5 is provided with at least one and is vertically arranged corresponding to the outside of the vertical beam 3 in each assembly through hole 2; the table top 5 can be flipped relative to the vertical beam 3 and maintained in a horizontal state under the action of external force, or flipped relative to the vertical beam 3 and restored to a vertical state.

[0046] In this technical solution, a vertical beam is installed inside the armrest frame. The vertical beam is hinged to the table top. Therefore, under the action of external forces, the table top can be tilted out relative to the vertical beam and maintained in a horizontal position, allowing users to place items or work, thus replacing the function of traditional sofa side tables, saving space and reducing configuration costs. Lowering the table top vertically close to the armrest can maintain the overall aesthetics of the seat and save design space.

[0047] like Figures 1-3As shown, the armrest frame 1 has an assembly through-hole 2, into which two vertical beams 3 are longitudinally welded. The two vertical beams 3 are each hingedly connected to a tabletop 5 via a hinge 4. The lower end of the armrest frame 1 is flush with the lower end of the seat. In this technical solution, the lower end of the armrest frame is flush with the lower end of the seat, maintaining the overall aesthetics of the seat. The provision of the vertical beams within the armrest frame enhances its structural strength. Furthermore, when the tabletop is flipped to a horizontal position, it aligns closely with the upper inner wall of the armrest frame, ensuring ease of use.

[0048] like Figures 7 and 8 As shown, a horizontal beam 6 is welded transversely within the armrest frame 1 to form two assembly holes 2 therein. Two vertical beams 3 are welded longitudinally within the upper assembly holes 2. The two vertical beams 3 are hingedly connected to a tabletop 5 via hinges 4. The lower end of the armrest frame 1 is supported on the ground. In this technical solution, the lower end of the armrest frame is supported on the ground, providing support for the seat and improving the overall stability of the seat.

[0049] like Figures 9 and 10 As shown, a horizontal beam 6 is welded transversely in the armrest frame 1 to form two assembly holes 2 in the armrest frame 1. Two vertical beams 3 are welded longitudinally in the two assembly holes 2 respectively. The two vertical beams 3 in each assembly hole 2 are hinged to a table board 5 respectively. The lower end of the armrest frame 1 is supported on the ground. In this technical solution, the lower end of the armrest frame is supported on the ground, which can support the seat and improve the overall stability of the seat. At the same time, two table boards are hingedly arranged in the armrest frame to increase the usable area. For example, the lower table board is used to place personal belongings, and the upper table board can be used to store office supplies such as laptops.

[0050] like Figure 4 and Figure 9 As shown, the hinge 4 includes a short connecting section 7 and a long connecting section 8 that are hinged together. One connecting section is fixedly connected to the vertical beam 3, and the other connecting section is fixedly connected to the table top 5. In this technical solution, the hinge includes a short connecting section and a long connecting section that are hinged together. The table top and vertical beam can be fixedly connected to the short connecting section or the long connecting section according to their size, which provides greater flexibility.

[0051] like Figures 3 to 6 As shown, the short connecting section 7 and the long connecting section 8 are constructed with U-shaped connecting grooves, which are arranged opposite to each other and the adapter frame of the short connecting section 7 is arranged on the outer side of the upper part of the long connecting section 8. The two are connected by a first connecting pin 9 so as to be relatively rotatable.

[0052] Limiting holes 10 are longitudinally provided on both sides of the long connecting section 8, a second connecting pin 11 is passed through the lower part of the short connecting section 7, and third connecting pins 12 are passed through the limiting holes 10 on both sides. The two ends of the second connecting pin 11 and the two ends of the third connecting pin 12 are respectively connected with limiting plates 13; when the short connecting section 7 and the long connecting section 8 rotate relative to each other, the limiting plates 13 are driven to move, thereby pulling the third connecting pin 12 to move longitudinally on the limiting holes 10;

[0053] A locking member is provided in the connecting groove of the long connecting section 8 , and the locking member is configured to lock the third connecting pin 12 on the limiting hole 10 when the short connecting section 7 and the long connecting section 8 are at a right angle.

[0054] In the above technical solution, when the short connecting section and the long connecting section are relatively unfolded, the linkage limiting plate drives the third connecting pin to move in the limiting hole. When the third connecting pin moves to a certain distance in the limiting hole, the third connecting pin can be locked by a locking member, thereby keeping the table top in a horizontal state, so that objects can be placed or used for office work.

[0055] Furthermore, the locking part includes a U-shaped locking block 14, a fourth connecting pin 15 and a torsion spring. The fourth connecting pin 15 is passed through the long connecting section 8 and the U-shaped locking block 14 and is located on the outside of the limiting hole 10. The torsion spring is sleeved on the fourth connecting pin 15. The U-shaped locking block 14 is located on the outside of the torsion spring. The torsion arms on both sides of the torsion spring abut against the upper and lower sides of the inner wall of the U-shaped locking block 14; when the table top is flipped to a horizontal state, the third connecting pin 12 moves to the upper part of the limiting hole 10, and the upper end of the U-shaped locking block 14 can be supported on the lower end of the third connecting pin 12, so that the third connecting pin 12 and the limiting plate 13 are in a locked state. In this technical solution, the locking part includes a U-shaped locking block 14, a fourth connecting pin 15 and a torsion spring. When the third connecting pin moves upward, the upper part of the U-shaped locking block is squeezed and moved to the upper end of the limiting hole, and the U-shaped locking block is reset to support the lower end of the third connecting pin under the action of the torsion spring, so that the third connecting pin can maintain the upper end of the limiting hole, and then the limiting plate and the second connecting pin are in a locked state, and the table top is stable in a horizontal state. The design of multiple hinges can improve the load-bearing capacity of the table top; in this case, the two hinge designs make the table top bear a load of about 50KG, with a high load-bearing capacity that can meet daily use. When unlocking, just press the outside of the U-shaped locking block, the inner end of the U-shaped locking block will rise, the third connecting pin will fall, and the table top will reset. It should be noted here that, if Figure 6 As shown, if the short connecting section is fixed on the vertical beam, the third connecting pin moves laterally when it is in the limiting hole. Figure 4 As shown, if the long connecting section is fixed on the vertical beam, the third connecting pin moves longitudinally in the limiting hole.

[0056] Furthermore, the outer ends of the long connecting section 8 are provided with receiving openings 16 on both sides thereof for cooperating with the second connecting pin 11; when the short connecting section 7 is fixed to the vertical beam 3, an arc-shaped buffer groove 18 is provided on the vertical beam 3, and when the table top 5 is flipped to a vertical state, the U-shaped locking block 14 corresponds to the arc-shaped buffer groove 18. In this technical solution, the provision of the receiving openings enables the second connecting pin to be accommodated in the receiving openings of the long connecting section when the long connecting section and the short connecting section are closed, thereby making the table top closer to the armrest in the initial vertical state and more aesthetically pleasing. In addition, the provision of the arc-shaped buffer grooves reduces the abnormal noise generated by the collision between the U-shaped locking block and the vertical beam when the table top is flipped to a vertical state, thereby better protecting the U-shaped locking block.

[0057] Furthermore, the armrest frame 1 is integrally formed, and a plurality of fixing holes 17 are provided on the armrest frame 1 or the crossbeam 6 to connect with the seat. In this technical solution, the entire armrest frame is integrally formed, and the structure is stable; the fixing holes are provided for fixed connection with the seat or backrest. Example 2:

[0058] A seat comprises an armrest with a foldable tabletop according to the first embodiment.

[0059] In this specific embodiment, in order to solve the problem that existing single seats do not have enough space, making it inconvenient for users to place items or work, and that side tables need to be configured to match the single seats, resulting in a large space occupation and configuration costs, the above solution designs a folding table on the side of the armrest. When the table is flipped out and kept in a horizontal state, the user can place items or work, thereby replacing the function of the traditional sofa side table, saving space and reducing configuration costs.
