that is, the power-assisted standing mechanism of the present invention has two modes of action, one is fixed adjustment: after the length of the rod B is adjusted, the rod B is fixed, so that the node O is fixed, and the rod E can only rotate around the node O; at the moment, the rod D stretches and contracts to drive the rod F to rotate around the point P, so that the rod G drives the rod E to rotate around the point O, and the back and forth switching process from sitting posture to standing posture can be realized;
and the second is dynamic adjustment: when the rod E is horizontal, if the rod D stretches at a constant speed, the rod F is driven to rotate clockwise around the P, the left end of the rod E is driven to move upwards through the rod G, if the rod B stretches gradually according to a certain proportion, the rod C can rotate clockwise around the point Q, the node O is driven to move upwards, if the proportion is proper, the rod E can move upwards horizontally and the angle is inconvenient, and the state 1 to the state 2 shown in the figure 6 are completed; likewise, the rod E can be moved downwards by shortening the rod D and the rod B; thereby realizing the function of height adjustment when keeping the seat level, the adjusting range is twice the length of the rod C.
It should be noted that, the power-assisted standing mechanism in the invention has the following working states: as shown in fig. 10, in the state 3, the lifting cylinder is adjusted to ensure the level of the seat beam by adjusting the connecting rod assembly, and the upper telescopic beam and the lower telescopic beam are adjusted to be shorter, so that the state 4 can be achieved, and the lumbar support is moved forwards relatively under the condition that the lumbar support is unchanged relative to the seat cushion, so that the device can be suitable for the user with a more enlarged figure, and the device can be used for the user with a more thin figure by adjusting the opposite direction;
as shown in fig. 10, in the state 3, the lifting electric cylinder is adjusted to be longer by adjusting the connecting rod assembly, the horizontal of the seat beam is ensured by adjusting the length of the lifting electric cylinder, the upper telescopic beam and the lower telescopic beam are adjusted to be longer, the state 5 can be achieved, the front and rear positions of the waist-off relative seat cushion are unchanged, the relative height is increased, the use of a higher user can be adapted, and the use of a shorter user can be adapted by the reverse adjustment in the same way. By combining the two adjusting methods, the device can be suitable for users with various heights, fatness and thin in a certain range.
