[0042] Here, the technical solutions in the embodiments (or "implementations") of the present application will be described clearly and completely in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0043] If there are terms involving directional indications or positional relationships in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance.

[0044] Next, the embodiments of this specification are described in detail.

[0045] Reference Figure 1 As shown, the present application discloses a seat, including a seat frame and an armrest assembly 20. The seat frame includes an armrest connector 11. The armrest assembly 20 includes an armrest member 21 and a universal connector 22, and the armrest member 21 and the universal connector 22 are fixed by assembly; the universal connector 22 is detachably fixed to the armrest connector 11.

[0046] Specifically, the armrest 21 and the universal connector 22 are assembled and fixed by glue. The armrest 21 is located outside the universal connector 22 and covers the universal connector 22 to ensure the beauty of the armrest 21. In other optional embodiments, the armrest 21 and the universal connector 22 can also be fixed by fasteners, etc., as long as a detachable structure is achieved.

[0047] Reference Figure 2As shown, the armrest connector 11 is provided with a positioning member 113 and a support member 114, and the support member 114 and the positioning member 113 are arranged on opposite sides of the armrest connector 11. A positioning hole 221 adapted to the positioning member 113 is correspondingly provided on the universal connector 22. A guide groove 222 with an upward opening is also provided on the universal connector 22, and the guide groove 222 is connected with the positioning hole 221, so that the positioning member 113 moves from the guide groove 222 to the positioning hole 221. In this way, it can be ensured that the interfaces of the armrest connector 11 and the universal connector 22 can be aligned before being fixed by screws to improve assembly accuracy.

[0048] When the positioning member 113 moves into the positioning hole 221, there is an overlap between the top of the positioning member 113 and the universal connector 22 in the vertical direction. In this way, the universal connector 22 can limit the positioning member 113 to facilitate assembly.

[0049] The universal connector 22 is provided with a plurality of first interfaces 223, and the armrest connector 11 is provided with a plurality of second interfaces 111 corresponding to the first interfaces 223. The first interfaces 223 and the second interfaces 111 are fixed by screws (not shown in the figure). In this way, the armrest assembly 20 can be fixed on the seat frame.

[0050] Reference Figure 3 As shown, four first interfaces 223 are provided on the universal connector 22, two first interfaces 223 are arranged at the front end edge of the universal connector 22 and arranged up and down, one first interface 223 is arranged in the middle of the rear end of the universal connector 22, and one first interface 223 is arranged at the lower edge of the middle part of the universal connector 22.

[0051] The length of the two first interfaces 223 in the horizontal direction is B, which is greater than half of the maximum length of the universal connector 22 in the horizontal direction. The length of the two first interfaces 223 in the vertical direction is A, which is greater than half of the maximum length of the universal connector in the vertical direction. In this way, the four first interfaces 223 can pass through the entire universal connector 22 in the horizontal and vertical directions, thereby ensuring the connection stability between the armrest assembly 20 and the seat frame.

[0052] The armrest 21 is located outside the universal connector 22 and shields the universal connector 22, and also shields the screws fixed on the universal connector 22, making the overall structure of the seat beautiful. Of course, the position and number of the interfaces mentioned here can be adjusted in combination with the shape, size and other factors of the universal connector 22, and the details are not repeated here.

[0053] Reference Figure 2 and Figure 4As shown, the top of the universal connector 22 is provided with a first arc-shaped notch 224 that is concave downwards, and the top of the armrest connector 11 is correspondingly provided with a second arc-shaped notch 112 that is concave downwards. In this way, while reducing its own weight, it can better adapt to the shape of the seat and provide installation space for other components.

[0054] The armrest 21 includes a vertical plate 211 and a flat plate 212. The flat plate 212 is located on the top of the vertical plate 211 and extends outward. In this way, the armrest 21 is assembled on the seat frame through the vertical plate 211, and the user's hands are supported by the flat plate 212. The front edge 2111 and the rear edge 2112 of the vertical plate 211 are both arranged in an arc shape. In this way, the armrest 21 can be ensured to have a beautiful structure while reducing the edges and corners on the vertical plate 211, which is highly safe.

[0055] By setting up a split armrest assembly 20, the armrest assembly 20 is disassembled into a universal connector 22 and an armrest member 21 that are assembled with each other. When changing the shape of the seat, it is not necessary to replace the entire armrest assembly 20, but only the armrest member 21. Therefore, under the same structure, fast switching can be achieved, and the structure is simple. For the same series of products, the seat frame and the universal connector 22 are universal structures. When switching the shape, it is only necessary to redesign the armrest member 21, and there is no need to redesign the universal structure. Not only can the rapid switching of the series of products be achieved, but also the manufacturing cost is reduced.

[0056] Reference Figure 1 As shown, the seat frame also includes a base 70 and a crossbar 71, and the crossbar 71 is mounted on the base 70, for example, it can be connected by threads, so as to facilitate disassembly and transportation. In addition, the handrail connector 11 is fixed to both ends of the crossbar 71, for example, the handrail connector 11 and the crossbar 71 are integrally formed to improve the connection stability between the two.

[0057] The seat frame also includes a seat frame 10, and two sides of the seat frame 10 are respectively provided with universal installation openings 101, and the universal installation openings 101 can be equipped with more than two functional connectors to provide personalized needs, meet the preferences of different consumers, and be more competitive. The specific structure of the optional two functional connectors on the seat frame 10 is described below.

[0058] Reference Figure 5-6 A functional connector 30 of the seat is shown, which includes a mounting plate 31 and a functional plate 32. The functional plate 32 is bent and extended from the mounting plate 31, and the mounting plate 31 is fixed to the universal mounting opening 101. Specifically, the mounting plate 31 is provided with a mounting hole 311 corresponding to the universal mounting opening 101, and the universal mounting opening 101 and the mounting hole 311 are locked by fasteners.

[0059] The universal mounting opening 101 is arranged at the bottom of the seat frame 10, the mounting plate 31 is abutted against the lower surface of the seat frame 10, and the mounting hole 311 and the universal mounting opening 101 are fixedly connected by screws. Of course, the universal mounting opening 101 can also be arranged at the side or upper part of the seat frame 10. In addition, a limiting portion 321 is arranged on the function plate 32, and the limiting portion 321 is a longitudinal depression arranged along the front-rear direction of the function plate 32, and the support member 114 can slide along the limiting portion 321.

[0060] Reference Figure 7-8 Another functional connector 30' is shown as an optional seat. Each functional connector 30' includes a mounting plate 31', a functional plate 32' and a connecting plate 33'. The functional plate 32' and the connecting plate 33' are arranged on both sides of the mounting plate 31' and extend from the mounting plate 31' respectively. The mounting plate 31' is fixed to the universal mounting port 101. Specifically, the mounting plate 31 is provided with a mounting hole 311' corresponding to the universal mounting port 101, and the universal mounting port 101 and the mounting hole 311' are locked by fasteners.

[0061] The universal mounting opening 101 is provided at the bottom of the seat frame 10, and the mounting plate 31 is attached to the lower surface of the seat frame 10. The mounting hole 311' and the universal mounting opening 101 are fixedly connected by screws. In addition, a limiting portion 321' is provided on the function plate 32', and the limiting portion 321' is a longitudinal depression provided along the front-rear direction of the function plate 32', and the support member 114 can slide along the limiting portion 321'.

[0062] The seat also includes a footrest assembly 50, which includes a support rod 51 and a footrest 52. A first fixing portion 322' is provided on the function board 32', and the support rod 51 is passed through the first fixing portion 322'. In another embodiment, a second fixing portion 331' is provided on the connecting plate 33', and the support rod 51 is passed through the first fixing portion 322' and the second fixing portion 331'. Of course, the support rod 51 can also be passed through the second fixing portion 331' alone. The first fixing portion 322' and the second fixing portion 331' are through holes, and the first fixing portion 322' is arranged on the rear side of the function board 32' and is located below the limiting portion 321'.

[0063] Reference Figure 7 As shown, the footrest 52 is a multi-link mechanism, including at least a first link 521 and a second link 522. The first link 521 is rotatably mounted on the support rod 51, and the second link 522 is rotatably mounted on the connecting plate 33'. In this way, the footrest 52 can extend from the bottom to provide foot support for the user. In addition, since the first links 521 of the left and right footrests 52 are connected to the same support rod 51, the synchronous movement of the left and right footrests 52 can be achieved.

[0064] The position-limiting portion 321' is tilted backward from top to bottom, and the corresponding seat frame 10 is also tilted backward from top to bottom. In this way, the seat frame 10 can be easily moved forward and backward under its own gravity and external gravity. In addition, the front end size of the functional board 32' is smaller than the rear end size, which can reduce weight and avoid other components.

[0065] Reference Figure 1 and 5 As shown in Figure 7, the seat frame 10 includes a front frame 102 and a rear frame 103. The seat frame also includes an adjustment device 40, which is installed between the front frame 102 and the rear frame 103 so that the front frame 102 can rotate relative to the rear frame 103. In this way, the seat frame 10 is decomposed into the front frame 102 and the rear frame 103, and the rear frame 103 can rotate relative to the rear frame 103 through the adjustment device 40 to meet the different height requirements of users.

[0066] The front frame 102 includes a front beam 1021 and a pair of first side beams 1022 located on both sides of the front beam 1021. The rear frame 103 includes a rear beam 1031 and a pair of second side beams 1032 located on both sides of the rear beam 1031. The front frame 102 and the rear frame 103 together form a U-shaped closed frame.

[0067] The front beam 1021 and the rear beam 1031 are arc-shaped structures with openings upward. In this way, the front beam 1021 and the rear beam 1031 are covered with more fillers, which are softer when touched by users, thereby improving the user experience. The front beam 1021, the first side beam 1022, the rear beam 1031 and the second side beam 1032 are square tube structures, and the square tube is a hollow structure. In this way, the overall weight of the seat can be reduced.

[0068] The rear frame 103 is arranged in an inclined shape, wherein the front end height of the rear frame 103 is higher than the rear end height of the rear frame 103. In this way, the rear frame 103 is convenient to move backwards when subjected to its own gravity and the user's thrust, so that the seat is switched from a sitting position to a lying position. The length of the second side beam 1032 is greater than the length of the first side beam 1022. In this way, the adjustment section of the seat frame 10 is arranged at the front end, which can better adapt to the support height of the legs.

[0069] The front frame 102 can rotate up and down relative to the rear frame 103. The front frame 102 has a first position and a second position, the first position is located above the second position, and the front frame 102 has a plurality of adjustment positions between the first position and the second position. In this way, the user can lock at any position between the first position and the second position according to the actual height, and the adjustment is flexible.

[0070] The front beam 1021 and the first side beam 1022 form a first support surface, and the rear beam 1031 and the second side beam 1032 form a second support surface. When the front frame 102 is located at the first position, the first support surface and the second support surface are flush, and the first side beam 1022 and the second side beam 1032 located on the same side are located on the same straight line. When the front frame 102 is located at other positions, the first support surface and the second support surface are set at an angle.

[0071] Reference Fig. 9 As shown, the adjusting device 40 includes a rotating member 41, a matching member 42 and an adjusting member (not shown in the figure), the rotating member 41 is arranged at the rear end of the first side beam 1022, and the matching member 42 is arranged at the front end of the second side beam 1032; the rotating member 41 and the matching member 42 are rotated and matched through the adjusting member. The adjusting member is a ratchet structure. In this way, the locking position of the front frame 102 between the first position and the second position can be more stable to avoid shaking.

[0072] The front frame 102 can be rotated to the upper part of the first position, the adjusting device 40 is in the unlocked state, and the front frame 102 can be returned to the second position. Of course, an additional unlocking device can also be provided, so that the user does not need to rotate it to the upper part of the first position to unlock it.

[0073] The seat also includes a backrest assembly 60 , which is rotatably mounted on the rear frame 103 via a backrest connector 61 .

[0074] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without causing conflicts. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the drawings; all modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this application should be included in the scope of protection of this application.
