The utility model adopts the following technical scheme:
a cushion with adjustable softness comprises a cushion frame and a soft cushion coated outside the cushion frame, wherein the cushion frame comprises a mounting frame, a chain wheel and a spring; the mounting frames are symmetrically arranged, and mounting grooves are formed in the mounting frames; the chain is arranged in the mounting groove of the mounting rack and can slide in the mounting groove; the chain wheels are arranged in the chain in a matching mode, one side of each chain wheel is provided with a connecting part, and the other side of each connecting part is connected with the mounting plate; the spring includes the serpentine spring that a plurality of elastic coefficient is different, serpentine spring is the circumference and sets up on the mounting panel, and connects between the mounting panel that the symmetry set up.
Preferably, first connecting columns are arranged between the symmetrically arranged mounting frames and located on the front side and the rear side of the mounting frames.
Preferably, a second connecting column is arranged between the symmetrically arranged connecting parts.
Preferably, the springs are uniformly arranged inside the chain.
Preferably, the mounting panel is discoid, and serpentine spring is the circumference and welds at the mounting panel edge.
Preferably, the mounting plate is located inside the sprocket.
A sofa comprises the cushion with adjustable hardness
Preferably, a driving motor is connected to the outer side of the chain wheel.
Preferably, the driving motor is installed in the sofa armrest and electrically connected with the controller.
Preferably, the sofa further comprises an operation panel, wherein the operation panel is arranged on the surface of the sofa armrest and is electrically connected with the controller.
Compared with the prior art, the utility model has the advantages of it is following:
1. the springs with different elastic coefficients are changed through the rotation of the chain wheel to change the elasticity of the surface of the cushion to change the hardness of the cushion, and the operation is convenient.
2. The chain wheels rotate to enable the chain motion directions of the upper side and the lower side of other chain wheels to be opposite, so that the chain wheels cannot move left and right and only rotate in situ, and dislocation cannot occur.
3. The hardness of the cushion can be changed without using a plurality of cushions with different hardness, and the space is saved to a greater extent.
4. The utility model discloses satisfy the humanized design (Close) in the 3C sitting sense system.
