[0034] Refer to Figure 1, An armrest, comprising: a bracket 100, a rotating joint 200, a supporting seat 700, and a locking structure 220; the rotating joint 200 is connected to the bracket 100, and the rotating joint 200 can rotate relative to the bracket 100; the supporting seat 700 is movably connected to the rotating joint 200 and can rotate relative to the rotating joint 200; wherein, the supporting seat 700 can be flipped up or flipped down relative to the bracket 100 through the rotating joint 200; the locking structure 220 is arranged on the rotating joint 200 and is used to lock the rotating position of the supporting seat 700; wherein, the locking structure 220 can lock at least three different facing angles between the supporting seat 700 and the bracket 100 respectively. The bracket 100 can be connected to a chair, so that the supporting seat 700 can extend from the chair and can support the arm of the occupant. After the supporting seat 700 moves relative to the bracket 100 through the rotating joint 200, its orientation can be changed, so that the occupant can adjust the orientation of the armrest, and further facilitate the support of the arm of the occupant in different facing states. The locking structure 220 can provide locking points at multiple rotating positions between the supporting seat 700 and the bracket 100. Therefore, the supporting seat 700 can be fixed at multiple different rotating positions, so as to provide multiple fixed support positions for the arms of the occupant, and further adapt to the arm placement requirements of the occupant and improve the riding experience of the occupant.

[0035] In some embodiments, referring to Figure 3 , the rotating joint 200 includes a base 210, a rotating seat 221, and a support frame 230 connected in sequence. The base 210 is connected to the bracket 100, and the support frame 230 is connected to the supporting seat 700; the rotating seat 221 can rotate relative to the support frame 230, and the locking structure 220 is located between the rotating seat 221 and the support frame 230 and locks the two relatively. When the rotating seat 221 and the support frame 230 rotate relative to each other, the supporting seat 700 and the bracket 100 can be flipped relative to each other, so that the effect of effectively adjusting the facing angle of the supporting seat 700 can be achieved. Moreover, the locking structure 220 can automatically lock the rotating seat 221 and the support frame 230 relatively after the rotational driving force between them is removed, so as to ensure that the supporting seat 700 can stably support the arm of the occupant, and further improve the riding experience of the occupant.

[0036] It can be envisaged that the supporting seat 700 can also be directly hinged to the bracket 100. The specific implementation manner is not unique, but can be adjusted accordingly according to the actual situation, and is not limited here.

[0037] In some embodiments, referring to Figure 4, the rotating seat 221 is provided with a rotating shaft 225, an outer periphery of the rotating shaft 225 is sleeved with a connecting seat 227, and the connecting seat 227 is connected to the support frame 230; the rotating seat 221 is provided with a reset torsion spring 228, and the reset torsion spring 228 is connected to the connecting seat 227 and can drive it to rotate relative to the rotating seat 221. The rotating shaft 225 can relatively position among the rotating seat 221, the connecting seat 227 and the support frame 230, so that the rotational movement of the connecting seat 227 can be carried out more stably and drive the support frame 230 to carry out rotational movement. After the locking structure 220 removes the connection effect on the support frame 230, the reset torsion spring 228 drives the connecting seat 227 to rotate back by itself, and then the automatic reset effect of the supporting seat 700 can be smoothly achieved, so as to facilitate its re-adjustment.

[0038] Specifically, the rotating shaft 225 is rotatably installed on the rotating seat 221 and fixedly connected to the connecting seat 227. A clamping groove is provided in the middle of the rotating shaft 225, and one end of the reset torsion spring 228 is clamped in the clamping groove.

[0039] In some embodiments, referring to Figure 5 , the middle part of the rotating seat 221 has a gap, the rotating shaft 225 passes through the gap, and the connecting seat 227 is rotatably installed in the gap; the reset torsion spring 228 is located outside the gap, the reset torsion spring 228 is connected to the rotating shaft 225 and can drive the connecting seat 227 to rotate through it. The connecting seat 227 is installed in the gap, and the rotating seat 221 can then guide and limit the movement of the connecting seat 227, so as to ensure that the rotational movement of the connecting seat 227 can be carried out more stably. Moreover, the rotating seat 221 can also position and install between the reset torsion spring 228 and the connecting seat 227, so that the installation positions of each component can be distributed orderly, and then the problem of interference when each component moves relative to each other can be avoided.

[0040] In some embodiments, referring to Figure 6, the locking structure 220 includes a lock block 226 installed on the connecting seat 227. The rotating seat 221 is provided with a positioning hole 222, and a part of the lock block 226 is movably installed in the positioning hole 222. A plurality of positioning steps 223 are provided on the side wall of the positioning hole 222, and the lock block 226 can abut against and be fixed to at least one of the positioning steps 223. When the connecting seat 227 moves, it will drive the lock block 226 to move relative to the positioning hole 222. During the movement of the lock block 226, the lock block 226 will come into contact with the positioning step 223, and the positioning step 223 will abut against and lock the lock block 226, thereby achieving the effect of locking the position of the support seat 700. By contacting the lock block 226 with different positioning steps 223, the locking effect of the support seat 700 at different positions can be switched. Therefore, it can effectively ensure that the support seat 700 has a variety of fixed orientation states, and further ensure that the support seat 700 can support the handle of the occupant under various arm placement requirements.

[0041] It can be envisioned that the locking structure 220 can also be composed of other components. For example, it can be rotationally driven by a gear, and a pin-like component is used to position and fix one of the multiple positioning holes 222 on the gear. Therefore, the specific implementation manner of the locking structure 220 is not unique, but can be adjusted according to the actual situation and is not limited here.

[0042] In some embodiments, referring to Figure 7 , the positioning steps 223 are sequentially connected along the rotation arc direction of the connecting seat 227. The positioning steps 223 sequentially connected along the arc direction can ensure that during the rotation of the connecting seat 227, the positioning steps 223 can always maintain the alignment contact effect with the lock block 226, and ensure that the lock block 226 can leave the positioning step 223 under the condition of external force application, thereby avoiding the problem of the lock block 226 being locked at the positioning step 223.

[0043] In some embodiments, referring to Figure 8 , the connecting seat 227 is provided with an installation hole 229, and the lock block 226 is movably installed in the installation hole 229. An elastic member 224 is arranged in the installation hole 229, and the elastic member 224 is used to elastically push the lock block 226 to one side of the installation hole 229. When the occupant adjusts the position of the support seat 700, a force will be applied to the lock block 226, causing it to move relative to the installation hole 229, thereby ensuring that it can move through the positioning step 223. The elastic member 224 can quickly and automatically drive the lock block 226 to reset after the lock block 226 moves through the positioning step 223, so as to ensure that when the lock block 226 contacts the positioning step 223 and the external force is removed, the lock block 226 can provide a positioning and fixing effect.

[0044] Specifically, the elastic member 224 is an elastic reed piece installed in the installation hole 229.

[0045] In some embodiments, referring to Figure 2 , the base 210 is rotatably connected to the end of the bracket 100. The mutual rotation between the base 210 and the bracket 100 enables the entire support seat 700 and the rotating joint 200 to be steered relative to the bracket 100, so as to cooperate with the rotating joint 200 to achieve a multi-dimensional rotation adjustment effect, and further ensure that the support seat 700 can be smoothly adjusted to the target state.

[0046] Specifically, a gear shaft is provided at the bottom of the base 210, and the bracket 100 is connected to the gear shaft and can rotate with it relative to the base 210.

[0047] In some embodiments, referring to Figure 3 , a connecting pile 235 is provided at the end of the support frame 230. The connecting pile 235 is rotatably connected with a rotating member 750, and the rotating member 750 is movably installed in the support seat 700. The rotational connection between the rotating member 750 and the support frame 230 enables the support seat 700 and the support frame 230 to be steered, so that a multi-dimensional steering adjustment effect can be achieved in cooperation with the rotation of the rotating joint 200, and further ensure that the support seat 700 can be smoothly adjusted to the target state.

[0048] A second aspect of the present utility model provides an embodiment of an office chair, including the above-mentioned armrest. The bracket 100 can be connected to the chair, so that the support seat 700 can extend from the chair and can support the arms of the occupant. After the support seat 700 moves relative to the bracket 100 through the rotating joint 200, its orientation can be changed, so that the occupant can adjust the orientation of the armrest, and further facilitate the support of the arms of the occupant in different orientation states. The locking structure 220 can provide locking points at multiple rotating positions between the support seat 700 and the bracket 100. Therefore, the support seat 700 can be fixed at multiple different rotating positions, so as to provide multiple fixed support positions for the arms of the occupant, and further adapt to the arm placement requirements of the occupant and improve the sitting experience of the occupant.

[0049] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0050] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those of ordinary skill in the art.
