[0033] With reference to Figure 3 and Figure 4 , the transmission assembly includes two support plates 11, the top of the support plate 11 is fixedly connected to the bottom of the seat cushion 4, the support plate 11 provides a stable bottom support structure for the seat cushion 4, and can effectively transmit the power of the transmission assembly to the seat cushion 4, driving the seat cushion 4 to change the position accordingly, the second connecting plate 13 is rotationally connected inside the support plate 11, the second connecting plate 13 plays a role in connecting and transmitting force in the transmission process, and can flexibly rotate in the support plate 11 according to the movement of other parts, realizing the effective transmission and direction conversion of power.
[0034] With reference to Figure 3 and Figure 4 , the limiting assembly includes two limiting plates 10, both of which are rotationally connected to the inner wall of the fixed frame 5, the limiting plate 10 can rotate in the inner wall of the fixed frame 5, and the movement trajectory of other parts is limited and guided by the change of the rotation angle of the limiting plate 10, the first connecting plate 9 is rotationally connected to the end of the limiting plate 10 away from the fixed frame 5, the first connecting plate 9 connects the limiting plate 10 with other parts, realizing the transmission of force and the coordination of movement, the third connecting plate 14 is rotationally connected to the end of the first connecting plate 9 away from the limiting plate 10, the third connecting plate 14 further transmits the force and participates in the movement coordination mechanism of the whole standing chair, cooperates with other parts to ensure the stability and accuracy of the seat cushion 4 in the process of rising and tilting.
[0035] With reference to Figure 1 and Figure 2The top of the seat body 1 is fixedly connected with two armrests 2, which can provide hand support for the user, facilitate the user to maintain body balance during standing up and sitting, and increase the safety and comfort of the user during use. The top rear side of the seat body 1 is fixedly connected with a back cushion 3, which provides support for the back of the user, reduces the pressure on the back of the user caused by long-time sitting, enables the user to maintain a relatively comfortable sitting posture, and also plays a certain auxiliary supporting role during standing up.
[0036] With reference to Figure 3 and Figure 4 , the output end of the electric push rod 6 is rotationally connected between the two first connecting plates 9, so that the extension and retraction force of the electric push rod 6 can be effectively transmitted to the first connecting plates 9, thereby driving other components connected thereto to move. Through this force transmission and conversion mechanism, the rising and tilting of the seat cushion 4 and the standing up assisting action are realized.
[0037] With reference to Figure 3 and Figure 4 , the first rotating plate 8 and the first connecting plate 9 are rotationally connected through a connecting rod, which provides stable structural support for the rotational connection between the first rotating plate 8 and the first connecting plate 9, ensures smooth relative rotation between the two, and makes the transmission of power between the two more stable and efficient, which is conducive to the coordinated operation of the movement mechanism of the whole standing-up chair.
[0038] With reference to Figure 3 and Figure 4 , the end of the second rotating plate 12 away from the first rotating plate 8 is rotationally connected to the end of the second connecting plate 13 away from the support plate 11, so that the second rotating plate 12 can transmit the power from the first rotating plate 8 to the second connecting plate 13, thereby driving the support plate 11 and the seat cushion 4 to move accordingly. In the whole transmission chain, it plays a key role in connection and power transmission, ensuring the continuity and accuracy of the standing-up action.
[0039] With reference to Figure 3 and Figure 4 , the end of the third connecting plate 14 away from the first connecting plate 9 is rotationally connected to the surface of the support plate 11, and the third connecting plate 14 and the second rotating plate 12 are rotationally connected through a connecting rod. Through the connection with the support plate 11 and the second rotating plate 12, the third connecting plate 14 further perfects the whole transmission and limiting system. During the movement of the seat cushion 4, it cooperates with other components to limit and guide the movement direction and angle of the seat cushion 4, so that the seat cushion 4 can rise, tilt and perform other actions according to the predetermined trajectory under the drive of the electric push rod 6, providing stable and effective standing-up assistance for the user.
[0040] Working principle: when the standing assistance function is needed to start, the electric push rod 6 starts to work. The output end of the electric push rod 6 performs the telescopic movement, and since it is rotationally connected between the two first connecting plates 9, the telescopic movement will make the first connecting plates 9 generate corresponding rotation and displacement changes. The movement of the first connecting plates 9 drives the limit plate 10 rotationally connected thereto to rotate in the inner wall of the fixed frame 5, and at the same time, makes the third connecting plate 14 rotationally connected to the other end of the first connecting plate 9 move, and the third connecting plate 14 rotates on the surface of the support plate 11 and cooperates to limit and guide the movement trend of the support plate 11.
[0041] At the same time, the movement of the first connecting plate 9 is transmitted to the first rotating plate 8 through the connecting rod, and the first rotating plate 8 rotates around the rotating shaft 7 to convert the linear movement of the electric push rod 6 into the rotating movement of itself. The rotation of the first rotating plate 8 further drives the second rotating plate 12 connected thereto to move, and the second rotating plate 12 rotationally connected to the end of the second connecting plate 13 away from the support plate 11, so as to make the second connecting plate 13 rotate inside the support plate 11, and finally transmit the power to the support plate 11.
[0042] The seat cushion 4 is fixedly connected to the top of the support plate 11, and under the coordinated movement of the above series of components, the seat cushion 4 will gradually rise from the initial horizontal position and tilt forward by a certain angle. In this process, the armrest 2 provides hand support for the user to maintain balance by force, and the back cushion 3 also assists in supporting the back of the user, helping the user to change from a sitting position to a standing position more easily. Throughout the process, the limiting assembly continues to play a role, ensuring that the movement trajectory of the seat cushion 4 is accurate and stable, preventing abnormal situations such as excessive displacement or shaking, thereby safely and effectively assisting the user to stand up.
