[0036] In the description of the utility model, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0037] Generally, the armrests and armrest brackets of seats are mostly fixed, which causes inconvenience and discomfort to users when sitting, which is not ergonomic. Some seats have a structure for rotating and adjusting the position of the armrests. However, the armrests are generally designed to rotate in the horizontal plane and always remain level with the ground. When users use them, their arms are often placed at different angles, and armrests that can only remain horizontal are difficult to adapt to the position of the arms when the user is leaning forward or leaning back. For example, when a user sits back and uses a mobile phone, the armrests set parallel to the ground cannot fit the arm well, and the arm support effect is poor. The user's comfort is poor and it cannot help reduce hand fatigue.

[0038] For this reason, Figures 1 to 4As shown, an armrest rotation structure proposed by the utility model includes a mounting support 100 for connecting with a seat, a transfer member 200 rotatably mounted on the mounting support 100, and an armrest body 300 mounted on the transfer member 200, wherein the mating surface between the transfer member 200 and the mounting support 100 is an inclined surface 101, so that when the transfer member 200 and the mounting support 100 rotate, the armrest body 300 can be driven to adjust the angle with the horizontal plane, and be used in an inclined arrangement state with the horizontal plane. It is easy to understand that when the transfer member 200 rotates, the armrest body 300 is driven to rotate together, and under the cooperation of the transfer member 200 and the inclined surface 101 of the mounting support 100, the armrest body 300 can be tilted relative to the ground, the structure is simple, and the user can easily adjust the armrest body 300 during use, so as to better support the user's arm position in different sitting postures, thereby improving the user's comfort. Optionally, the angle between the inclined plane 101 and the horizontal plane is A, which satisfies: 0°<A≤15°. It is easy to understand that the angle between the inclined plane 101 and the horizontal plane represents the maximum angle that can be changed by the transfer member 200 rotating 180°. For example, when A=15°, when the transfer member 200 gradually rotates 180°, the inclination angle of the armrest body 300 relative to the horizontal plane gradually changes by 15°. In some embodiments of the present invention, the angle between the inclined plane 101 and the horizontal plane is A=10°. When the transfer member 200 gradually rotates 180°, the inclination angle of the armrest body 300 relative to the horizontal plane gradually changes by 10°. In some applications, refer to Figure 3 and Figure 4 When the transfer member 200 is aligned forward relative to the seat, the armrest body 300 is parallel to the horizontal plane; when the transfer member 200 is rotated 180° and aligned backward relative to the seat, the armrest is inclined 10° relative to the horizontal plane.

[0039] In some embodiments, the inclined surface is arranged to be inclined downward toward the side away from the chair back, so that the armrest body can be adjusted to be inclined forward and downward relative to the seat (not shown in the figure), which is suitable for supporting the user's arms when the user is sitting forward. It should be noted that the direction of "the seat faces forward" can be understood as the direction of the front of the user's body when the user sits normally on the seat. Conversely, the direction of "the seat faces backward" can be understood as the direction of the back of the user's body when the user sits normally on the seat. For example, when the seat has a backrest, the transfer member 200 is slanted backward relative to the seat, which can be understood as the end of the transfer member 200 turning to one side of the chair back. Referring again to Figure 3 and Figure 4In some embodiments of the present invention, the inclined surface 101 is arranged to tilt downward toward one side of the chair back, so that the armrest body 300 can be adjusted to tilt downward relative to the seat, which is suitable for supporting the user's arm when the user sits back with his back against the chair back. In some applications, the user sits back and holds a mobile phone in his hand, and the armrest body 300 can be adjusted to tilt downward toward one side of the chair back, so that the armrest body 300 can better fit the arm, provide good support for the arm, and avoid fatigue caused by the arm hanging in the air for a long time.

[0040] In some embodiments, the transfer member is steplessly adjusted relative to the mounting support (not shown in the figure). For example, there is no fixed structure between the transfer member and the mounting support, and the two cannot be relatively fixed. However, the adjusted transfer member is easy to shift, which is not conducive to stably supporting the user's arm. In this regard, in some embodiments of the present invention, the mounting support 100 is connected to a positioning assembly 400, and the positioning assembly 400 is connected to the transfer member 200 and is used to position the transfer member 200. Furthermore, the adjusted transfer member 200 is not easy to shift and can stably support the user's arm. Specifically, as Figure 1 and Figure 2 As shown, the positioning assembly 400 includes a mounting plate 410, a first compression spring 420 and a fixing bead 430. The mounting plate 410 is fixedly connected to the mounting support 100 by screws. The first compression spring 420 and the fixing bead 430 are both installed on the mounting plate 410. The transfer member 200 has a plurality of first rotation gear slots 201 arranged at intervals around the rotation axis of the transfer member 200. The first compression spring 420 connects and drives the fixing bead 430 to press against the slot wall of the first rotation gear slot 201. It is easy to understand that the combination of the first compression spring 420 and the fixing bead 430 can be equivalent to a ball plunger, and the ball plunger is installed on the mounting plate 410. In application, when the transfer member 200 rotates around the normal line passing through the center of the inclined surface 101, the fixing bead 430 can float along the normal line parallel to the inclined surface 101, and finally get stuck in one of the first rotation gear slots 201. The angle between adjacent first rotation gear slots 201 is B, which represents the minimum rotation gear adjustment angle. Optionally, B=15°.

[0041] In some embodiments of the present invention, referring to Figure 1 and Figure 2 The armrest body 300 is slidably mounted on the transfer member 200, and the armrest body 300 has a displacement design to adapt to the state of the transfer member 200 after rotation. Figure 3 and Figure 4, the connection between the transfer member 200 and the mounting support 100 is located at one end of the transfer member 200, so that after the transfer member 200 is rotated relative to the mounting support 100, the position of the armrest body 300 changes greatly. For example, after the transfer member 200 turns to one side of the chair back, the armrest body 300 is offset to one side of the chair back by about the length of the transfer member 200. At this time, since the armrest body 300 can slide relative to the transfer member 200, the user can slide the armrest body 300 forward and adjust it to a position suitable for supporting the arm, thereby improving the comfort of use. In some applications, in order to ensure that the armrest body 300 always extends in the direction facing the front of the user's body, that is, the armrest body 300 is located below the arm of the seated user and arranged toward the front of the seat, in this regard, the transfer member 200 can only be rotated 180° in the application to perform the maximum angle adjustment. In order to overcome the above problems, in some embodiments of the present utility model, refer to Figure 5 The armrest body 300 is rotatably mounted on the transfer piece 200, which can overcome the position problem of the armrest body 300 in applications where the transfer piece 200 is not fully rotated. For example, the transfer piece 200 rotates less than 180°, and the remaining angle is adjusted by rotating the armrest body 300, so that the armrest body 300 is finally extended to the direction facing the front of the user's body to provide better support for the arm. In some applications, the transfer piece 200 is generally rotated outward toward the side away from the center of the seat to avoid collision with the human body or obstruction to the human body. It is easy to understand that according to the actual use needs of different users, the transfer piece 200 can be rotated inward for adjustment and use. Similarly, the armrest body 300 can also be rotated to a position inclined to the direction facing the front of the user's body for use. The specific use situation is not limited.

[0042] Refer to Figure 1 , Figure 2 and Figure 5, one end of the transfer member 200 away from the mounting support 100 is fixedly connected with a fixed disk 210, and a square rotating block 220 is sleeved on the outer side of the fixed disk 210, and the rotating block 220 is rotatably connected with the fixed disk 210. Among them, the fixed disk 210 is arranged with a plurality of second rotating gear slots 2101 at intervals around the rotating axis of the rotating block 220, and the rotating block 220 is installed with a third compression spring 223 and a plug-in block 224, one end of the third compression spring 223 is connected to the rotating block 220, and the other end is connected to and drives the plug-in block 224 to press against the slot wall of the second rotating gear slot 2101. Furthermore, the rotating block 220 has a plurality of rotation adjustment gears relative to the fixed disk 210, and the position of the rotating block 220 after rotation adjustment remains constant. Optionally, the angle between adjacent second rotating gear slots 2101 is 15°, and the minimum stable adjustment angle of the user is 15°. In some embodiments, a plurality of second rotation gear slots 2101 are evenly arranged along the circumference of the fixed disk 210, and there are two third compression springs 223 and two plug-in blocks 224. The third compression springs 223 and the plug-in blocks 224 are arranged one by one, and the two plug-in blocks 224 are arranged relatively to each other and respectively plugged with two symmetrical second rotation gear slots 2101, thereby improving the stability of the rotation adjustment of the rotation block 220. In addition, the armrest body 300 includes a mounting shell 310, and the mounting shell 310 is clamped with the armrest shell, and the armrest shell is used to support the arm. A sliding groove corresponding to the rotation block 220 is provided in the mounting shell 310, and the relative groove wall of the rotation block 220 abuts against the relative groove wall of the sliding groove, so that when the rotation block 220 rotates relative to the fixed disk 210, the rotation block 220 is connected and drives the armrest body 300 to rotate together.

[0043] Further, the transfer member 200 is connected with a second compression spring 221 and a fixed plug 222, and the mounting shell 310 is arranged with a plurality of sliding gear slots 3101 at intervals along the sliding direction of the mounting shell 310. One end of the second compression spring 221 is connected to the transfer member 200, and the other end is connected to and drives the fixed plug 222 to press against the slot wall of the sliding gear slot 3101. Furthermore, the rotating block 220 has a plurality of sliding gears relative to the mounting shell 310, and the position of the mounting shell 310 after sliding adjustment remains constant. Optionally, the distance between adjacent sliding gear slots 3101 is 12mm, and the minimum stable adjustment displacement of the user is 12mm. Specifically, the second compression spring 221 and the fixed plug 222 are both installed on the rotating block 220, and the sliding gear slot 3101 is set on the slot wall of the sliding slot of the mounting shell 310. One end of the second compression spring 221 is connected to the rotating block 220, and the other end is connected to and drives the fixed plug 222 to press against the slot wall of the sliding gear slot 3101. In some embodiments, there are two groups of sliding gear slots 3101, and the two groups of sliding gear slots 3101 are arranged opposite to each other on the opposite groove walls of the sliding groove. Correspondingly, there are two second compression springs 221 and two fixed plugs 222, and the second compression springs 221 and the fixed plugs 222 correspond to each other. The two fixed plugs 222 are arranged opposite to each other and respectively plugged with the two opposite sliding gear slots 3101, thereby improving the stability of the sliding adjustment of the mounting shell 310. It is easy to understand that when the rotating block 220 rotates relative to the fixed disk 210, the armrest body 300 rotates together with the rotating block 220, and the armrest body 300 can slide independently relative to the rotating block 220, so that the armrest body 300 has the functions of rotation adjustment and sliding adjustment. It is easy to understand that the two groups of sliding gear slots 3101 can also be arranged in a staggered manner on the opposite groove walls of the sliding groove.

[0044] The chair according to the embodiment of the utility model includes an armrest rotation structure according to the embodiment of the utility model. By adopting an armrest rotation structure according to the embodiment of the utility model, the transfer member 200 drives the armrest body 300 to rotate together when rotating. Under the cooperation of the transfer member 200 and the inclined surface 101 of the mounting support 100, the armrest body 300 can be tilted relative to the ground. The structure is simple, and the user can easily adjust the armrest body 300 during use to better support the user's arm position when sitting in different sitting postures on the chair, thereby improving the user's comfort.

[0045] Other structures and operations of the seat according to the embodiment of the utility model are known to those skilled in the art and will not be described in detail here.
