[0024] Please refer to Figures 1 to 4 The office chair for self-adaptive adjustment of the armchair is an embodiment of the present application, which comprises a support assembly 10, a seat cushion assembly 20 mounted on the support assembly 10, and an armchair assembly 30. The armchair assembly 30 comprises a first armchair part 31 mounted on the support assembly 10, an elastic part 32 arranged on the first armchair part 31, and a second armchair part 33 mounted on the elastic part 32. The first armchair part 31 is pivotally connected to the top of the second armchair part 33, and the bottom is elastically connected through the elastic part 32.

[0025] The working principle of the office chair for adaptive adjustment of a reclining chair is as follows: when a user leans on the reclining chair, the body exerts pressure on the reclining chair; since the second reclining chair part 33 is elastically connected to the first reclining chair part 31 through the elastic part 32, the pressure is transmitted to the elastic part 32; the elastic part 32 will deform after being subjected to the pressure, and is compressed or stretched according to the size and direction of the pressure; the first reclining chair part 31 is connected to the top pivot of the second reclining chair part 33, so that the second reclining chair part 33 can rotate relative to the first reclining chair part 31 within a certain range; when the back of the user leans on the reclining chair and exerts forces in different directions, the second reclining chair part 33 can rotate around the pivot, and the elastic part 32 at the bottom will correspondingly adjust the degree of deformation to adapt to the shape and action of the back of the user.

[0026] Compared with the prior art, the office chair for adaptive adjustment of a reclining chair can automatically adjust according to the body action and pressure of the user, and provide more conformable support for the back; the pivot connection allows the reclining chair part to rotate within a certain range, further enhancing the conformability of the reclining chair to the human body; the body shape, weight and sitting posture habit of different users are different, and this adaptive reclining chair can adjust to the characteristics of each user; for people who need to frequently change postures during work, the adaptive reclining chair can quickly respond to the change in posture, provide continuous comfortable support, and improve work efficiency and concentration.

[0027] Please refer to Figure 1 and Figure 3 , the support assembly 10 is fixedly connected to one end of the cushion assembly 20, and is hingedly connected to the other end. The support assembly 10 is fixedly connected to one end of the cushion assembly 20, which makes the cushion have a stable support point in the normal use state; this fixed connection ensures that the cushion will not move or shake unnecessarily at this end; when the user sits on the cushion, the fixed connection end can bear the weight of the human body and uniformly transmit it to the support assembly 10, providing a stable foundation for the entire office chair for adaptive adjustment of a reclining chair; when the user needs to adjust the sitting posture or find a more comfortable angle, the cushion can be rotated around the hinge point through the movement of the body or the application of external force; during the movement of the user, the hinged connection can dynamically adjust the cushion according to the action of the body.

[0028] Please refer to Figure 3 and Figure 4The support assembly 10 is provided with a connecting rod 40, one end of which is fixedly connected with the support assembly 10, and the other end is hingedly connected with the cushion assembly 20. The end of the connecting rod 40 fixedly connected with the support assembly 10 provides a stable foundation for the entire connecting structure; ensures that the connecting rod 40 will not easily loosen or detach from the support assembly 10 during use, thereby providing reliable support for the cushion assembly 20; the presence of the connecting rod 40 enhances the connection strength between the support assembly 10 and the cushion assembly 20; compared with a simple hinged connection, the connecting rod 40 can better withstand the weight from the cushion and the user, reducing the risk of deformation or damage at the connection site due to long-term use or external force; the other end of the connecting rod 40 is hingedly connected with the cushion assembly 20, allowing the cushion assembly 20 to rotate relative to the support assembly 10 to a certain extent; when the user adjusts the sitting posture or applies external force to the cushion, the cushion assembly 20 can rotate around the hinge point; this rotation can achieve different angle adjustments to meet the user's needs for different sitting postures; for example, the user can lean the body backward, causing the cushion assembly 20 to rotate backward to obtain a more comfortable reclining angle; or when leaning forward, the cushion assembly 20 can also correspondingly rotate forward to maintain support for the body.

[0029] Please refer to Figure 2 The office chair for self-adaptive adjustment of the recliner further comprises a rotating shaft piece 50, the first recliner piece 31 and the second recliner piece 33 are connected through the rotating shaft piece 50, the rotating shaft piece 50 comprises a shaft sleeve 51 installed on the first recliner piece 31 and a rotating shaft 52 sleeved on the first shaft sleeve 51, and the rotating shaft 52 is connected with the second recliner piece 33. The shaft sleeve 51 installed on the first recliner piece 31 provides a mounting and supporting position for the rotating shaft 52; the rotating shaft 52 sleeved on the shaft sleeve 51 is connected with the second recliner piece 33; when the second recliner piece 33 is subjected to external force or the user adjusts the sitting posture, the rotating shaft 52 will rotate in the shaft sleeve 51, thereby realizing the relative rotation between the first recliner piece 31 and the second recliner piece 33; when the user leans on the recliner and applies pressure to the recliner, the second recliner piece 33 will produce corresponding movement according to the direction and size of the pressure; if the user leans backward, the second recliner piece 33 will rotate backward, at which time the rotating shaft 52 rotates clockwise or counterclockwise in the shaft sleeve 51 to adapt to the angle change of the recliner; this rotation can be performed within a certain range, so that the recliner can adapt to different sitting posture needs; for example, the user can adjust the angle of the recliner from the upright state to gradually lean backward, and the rotating shaft 52 will continuously adjust the position as the angle of the recliner changes, ensuring smooth and stable rotation of the recliner.

[0030] Please refer to Figure 1 and Figure 2The elastic member 32 is a rubber column and a spring sleeved on the rubber column. The two ends of the rubber column are connected with the first and second reclining chair members 31 and 33 respectively, and the two ends of the spring are connected with the first and second reclining chair members 31 and 33 respectively. When the user leans on the reclining chair, the body exerts pressure on the reclining chair, which is transmitted to the rubber column. The rubber column deforms according to the size of the pressure, plays a buffering role, and reduces the impact of the instantaneous impact force on the structure of the reclining chair and the user's body. At the same time, the rubber column generates a certain counterforce during deformation, providing support for the user. The rubber column can adaptively adjust according to the shape and pressure distribution of the user's back. Different users have different back shapes and sitting habits, and the rubber column can adapt to the user's back through its deformation to provide more personalized support. The spring is sleeved on the rubber column, further enhancing the elasticity of the elastic member 32. When pressure acts on the reclining chair, the spring will be compressed together with the rubber column to store energy. The spring coefficient is usually higher than that of the rubber column, which can provide greater elastic recovery force, so that the reclining chair can recover to the initial state faster after being subjected to pressure. The spring plays an auxiliary role in the support of the reclining chair. When the user leans on the reclining chair, the spring will be compressed or stretched according to the size of the pressure, and together with the rubber column, it will bear the weight and pressure of the user. The presence of the spring can increase the support of the reclining chair, improve the stability and comfort of the reclining chair.
