[0039] The following is combined with Figure 1-11 , the specific implementation methods of the utility model are further described in detail to make the technical solution of the utility model easier to understand and grasp.

[0040] In this embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right", "end", "front", "back", "middle", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0041] In addition, in this specific embodiment, if the connection or fixing method between components is not specifically described, the connection or fixing method can be through bolt fixing or pin fixing, welding or pin shaft connection, etc. commonly used in the prior art, and therefore, it is not described in detail in this embodiment.

[0042] like Figure 1-5 As shown, an armrest 300 includes a support base 1, a connecting component 2, a support component 3 and an adjustment component 4. One end of the connecting component 2 is connected to the support base 1, and the other end is connected to the support component 3. The support component 3 can rotate relative to the connecting component 2. The connecting component 2 extends in an arm shape, and the inclination angle of the connecting component 2 relative to the support base 1 is adjustable (the inclination angle in this application can be understood as the angle formed by the support base 1 and the horizontal plane) to adjust the height of the support component 3 relative to the support base 1. The adjustment component 4 is connected between the support base 1 and the connecting component 2 to fix the connecting component 2 relative to the support base 1.

[0043] The adjustment assembly 4 includes a first adjustment member 41 and a second adjustment member 42. The first adjustment member 41 is formed with a locking area 411 and an unlocking area 412. The second adjustment member 42 is formed with at least one adjustment portion 421 that cooperates with the first adjustment member 41, that is, the adjustment portion 421 cooperates with the locking area 411 and the unlocking area 412. In this embodiment, three adjustment portions 421 are provided, which can relatively improve the stability of the cooperation between the adjustment portion 421 and the locking area 411; the unlocking area 412 is located on the locking area 411. Of course, in other embodiments, the unlocking area 412 is located below the locking area 41.

[0044] When the adjusting portion 421 is in the locking region 411 , the connecting component 2 can move toward the unlocking region 412 . When the adjusting portion 421 is in the unlocking region 412 , the connecting component 2 can move between the locking region 411 and the unlocking region 412 .

[0045] like Figure 5-6 As shown, the locking area 411 includes a plurality of locking gears 4111, which are arranged along the longitudinal direction of the first adjusting member 41. By providing a plurality of locking gears 4111, locking at different heights can be achieved to increase the adjustment range of the overall height.

[0046] The plurality of locking positions 4111 are provided with a first inclined surface 41111 on the same side of the arrangement direction, and the adjustment portion 421 is provided with a second inclined surface 4211 matching the first inclined surface 41111 on the side opposite to the first inclined surface 41111. When the height of the armrest needs to be adjusted, the user can apply an upward force to the support assembly 3. Through the guiding effect of the first inclined surface 41111 and the second inclined surface 4211, the second adjustment member 42 moves on the first adjustment member 41 to complete the upward height adjustment of the support assembly 3; when the height needs to be adjusted downward, the user continues to apply an upward force to the support assembly 3, so that the adjustment portion 421 leaves the last locking position 4111 and comes to the unlocking area 412. At this time, it moves downward to adjust the support assembly 3 downward; the side on which the first inclined surface 41111 and the second inclined surface 4211 are located depends on the direction in which the unlocking area 412 is located, which will not be described in detail here.

[0047] In this embodiment, the multiple locking gears 4111 include an initial gear (which can be a locking gear 4111 close to the mounting member 43 (the mounting member 43 described below)) and a final gear (which can be a locking gear 4111 close to the unlocking area 412). The adjustable height of each gear is different. During the movement of the adjusting portion 421 of the second adjusting member 42 from the initial gear to the final gear, when all reach the unlocking area 412, the second adjusting member 42 cannot move toward the initial gear; when all the adjusting portions 421 of the second adjusting member 42 move to the unlocking area 412, the second adjusting member 42 can move toward the initial gear direction; in order to achieve the limiting function, specifically, the locking gear 4111 is set as a flat surface on the other side of the first inclined surface 41111 in the arrangement direction. Similarly, the adjusting portion 421 is also set as a flat surface. Unlike the first inclined surface 41111 and the second inclined surface 4211, the cooperation of the two flat surfaces can limit the second adjusting member 42 and prevent the support assembly 3 from falling.

[0048] like Figure 5As shown, a first elastic member 422 cooperating with the second adjusting member 42 is provided at one end of the second adjusting member 42 , and the first elastic member 422 is used to support the second adjusting member 42 and restore the second adjusting member 42 to its initial state to cooperate with the first adjusting member 41 .

[0049] A mounting member 43 and a second elastic member 431 cooperating with the mounting member 43 are provided below the second adjusting member 42. The second elastic member 431 is used to restore the mounting member 43 to its initial state.

[0050] Specifically, the mounting member 43 is used to resist the second adjusting member 42 to prevent the first elastic member 422 from resetting and driving the second adjusting member 42 to move due to the lack of resisting action with the first adjusting member 41, and getting stuck in the unlocking area 412, causing the second adjusting member 42 to be unable to descend, affecting user use, while the second elastic member 431 can return the second adjusting member 42 to the initial position from the pressed position.

[0051] like Figure 2 As shown, the connecting component 2 includes a first connecting member 21 and a second connecting member 22. One end of the first connecting member 21 and the second connecting member 22 are respectively hinged to the support base 1, and the other end is respectively hinged to the support component 3, so that the connecting component 2 forms a four-bar structure. By providing the first connecting member 21 and the second connecting member 22, the positions where the first connecting member 21 and the second connecting member 22 are connected to the support base 1 and the support component 3 are respectively points A, B, C and D. The four points are connected and can be regarded as the first connecting member 21 and the second connecting member 22 forming a quadrilateral connecting rod structure. When the support component 3 moves up and down, the support component 3 can always remain horizontal, better cooperate with the user, and improve the use experience.

[0052] like Figure 4-5 As shown, the adjustment component 4 also includes a receiving part 44, and a through hole 441 is opened at the bottom of the receiving part 44, and the installation part 43 can be passed through the outside of the through hole 441. When the second adjustment part 42 moves to the initial gear, it will press the installation part 43 to move downward, and the installation part 43 will not be able to move far enough. In this way, the volume of the receiving part 44 needs to be increased. The increase in the volume of the receiving part 44 may correspondingly make other parts of the armrest larger, which will increase the manufacturing cost. In this embodiment, by opening a through hole 441 at the bottom of the receiving part 44, the installation part 43 can be passed through the outside of the through hole 441, which can reduce the volume of the receiving part 44 to achieve the demand of reducing manufacturing costs.

[0053] The second adjusting member 42 and the mounting member 43 are rotatably arranged in the accommodating member 44. One end of the first elastic member 422 is connected to the second adjusting member 42, and the other end is connected to the accommodating member 44. Specifically, the first elastic member 422 is a spring, and the second elastic member 431 is a torsion spring. The second adjusting member 42 and the mounting member 43 are provided with a rotating shaft. The second elastic member 431 is provided on the rotating shaft and cooperates with the mounting member 43. The second adjusting member 42 and the mounting member 43 are rotatably connected to the accommodating member 44 by means of the rotating shaft.

[0054] like Figure 1-2 As shown, the armrest 300 also includes a shell 9, which is arranged on the outer surface of the support base 1, the connecting component 2 and the connection between the connecting component 2 and the supporting component 3. The shell 9 can prevent the support base 1, the connecting component 2 and the adjustment component 4, and the connection between the connecting component 2 and the adjustment component 4 and the supporting component 3 from being damaged, and also ensures a certain degree of cleanliness of the armrest.

[0055] like Figure 1 and Figure 7 As shown, the support assembly 3 includes a mounting seat 31, a rotating assembly 5 and a supporting plate 6. The mounting seat 31 is provided with a receiving portion, and the receiving portion is open. The rotating assembly 5 is passed through the outside of the receiving portion and connected to the connecting assembly 2.

[0056] Specifically, the rotating component 5 includes a first assembly part 51 and a locking part 52 that is passed through the outside of the first assembly part 51. The first assembly part 51 includes a first assembly part 511 and a second assembly part 512. The first assembly part 511 is against the bottom surface of the accommodating part, and the second assembly part 512 is passed through the accommodating part.

[0057] The second assembly part 53 is arranged between the locking part 52 and the connecting component 2, and is connected to the locking part 52 and the connecting component 2. By providing the rotating component 5, the user can rotate the mounting seat 31 horizontally, further meeting the user's usage needs. Since the first assembly part 511 does not completely cover the accommodating part, in order to make the overall flatness and beauty, a cover body 54 can be provided on the first assembly part 511.

[0058] like Figure 1 As shown, the support assembly 3 also includes an adjustment seat 32, on which is mounted a support plate 6. The support plate 6 is slidably and rotatably connected to the adjustment seat 32. The adjustment seat 32 is also slidably connected to the mounting seat 31 to adjust the angle of the adjustment seat 32 relative to the mounting seat 31. This allows the support plate 6 to have functions such as tilting, forward and backward movement, and left and right rotation, providing more functions and better meeting user needs. The specific structure of this adjustment method can be referred to in application number 202410267884.0 and will not be described in detail here.

[0059] Through the arrangement of the above structure, the angle and position can be adjusted to the desired angle according to the user's different sitting postures or different usage environments, so as to enhance the user experience.

[0060] like Figure 8-11 As shown, a chair includes a seat assembly 100 and a backrest assembly 200 , and an armrest 300 is connected to the seat assembly 100 .

[0061] The seat assembly 100 includes a base 8 and a bottom member 7 connected to the base 8. The support base 1 can rotate relative to the bottom member 7 to further expand the adjustable range and meet more user needs. Specifically, the bottom of the support base 1 is provided with a support block 11 and a support plate 12. The bottom of the support block 11 is provided with two protrusions 111 connected to the support plate 12. After the support block 11 is installed on the bottom member 7, it is connected to the support plate 12 via the protrusions 111 to provide initial fixation. It is then connected to the bottom member 7 via bolts or other means. After that, the support base 1 can rotate relative to the bottom member 7.

[0062] The technical effects of this utility model are mainly reflected in the following aspects:

[0063] It can be adjusted to the desired angle and position according to the user's different sitting postures or different usage environments to enhance the user experience.

[0064] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementation methods. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention.
