It can be understood that the soft seat is a sofa, the sofa further comprises a support frame 50, a base 40 is arranged on the support frame 50, a cushion 42 is arranged on the base 40, the serpentine spring 41 is arranged at the bottom of the cushion 42, and the cushion 42 is adjusted while the serpentine spring 41 is adjusted. The furniture adjusting device is applied to adjusting the softness and hardness of the sofa. It will be appreciated that the furniture adjustment device of the present invention may be used with other furniture such as mattresses and the like. The controller 60 is mounted on the seat cushion 42 of the sofa. The controller 60 is used for controlling the forward and reverse rotation of the motor, so as to control the reciprocating movement of the moving member 11 along the axial direction of the transmission member.

In this embodiment, in order to improve the comfort of the sofa, the sofa is closer to the human body. The sofa is designed ergonomically by adopting the ergonomics principle. For example, the sofa seat with the height dimension of 41+/-2 cm is more suitable for the body shape of Chinese, and is more comfortable when sitting on the place with the lower leg vertical to the place. The arch height of the snake-shaped spring 41 is 4cm, the arch height of the snake-shaped spring 41 is too low, sitting feel is hard, the appearance is influenced by the arch height, the too high sofa cushion 42 can arch to influence the appearance, the appearance is attractive, the arch height of the snake-shaped spring 41 is 4cm, the rebound resilience is strong, and the long sitting is not easy to collapse.

The working principle of the furniture adjusting device for adjusting the softness and hardness of the sofa is as follows: the base 40 is provided with a plurality of rows of snake springs 41, the snake springs 41 form an arch structure, a controller 60 for controlling the starting of a motor is arranged on the side of a cushion 42, the motor is in physical work to enable the moving part 11 to move forwards and backwards, the motor can push 2cm forwards and backwards, the arch height of the snake springs 41 is driven to float up and down by +/-2 cm, the hardness of the cushion 42 is adjustable, and the hardness adjustment of sitting feeling of different people is met. The user is through operating the controller 60, and the controller 60 gives the instruction to the motor, and the motor rotates, drives drive mechanism, and when drive mechanism was screw mechanism, the motor rotated, and the worm gear assembly through the motor output drives the screw rod and rotates, because the other end and the screw rod screw thread transmission of moving part 11 are connected to drive moving part 11 and remove towards actuating mechanism 30, thereby compress serpentine spring 41, serpentine spring 41's arch height rises. Conversely, when the control mover 11 moves away from the driving mechanism 30, the serpentine spring 41 is stretched such that the arch height of the serpentine spring 41 is lowered. The softness and hardness degree of the sofa can be changed by changing the height of the arched height of the snake-shaped spring 41, so that the sofa can be adjusted to meet the softness and hardness requirements of different people, and the comfort is improved. It can be understood that, because the characteristics of the serpentine spring 41 and the difference of the receiving capacities of different people on the softness are small, the arcuate height of the serpentine spring 41 is driven to float up and down by ±2cm, and the control stroke is not required to be too long, thereby realizing the effect of reducing the operation time.

With continued reference to fig. 1-3, it will be appreciated that the stroke required to be adjusted is relatively short, but taking into account the depth factor of the soft seat, for example, when the soft seat is a sofa, the depth of the sofa is the distance from the back of the sofa to the knee fossa of the person at the front end of the sofa. In the actual installation process, in order to ensure the integrity of the base 40, the punching from the middle of the base 40 is avoided, the length of the regulator is consistent with or slightly deviated from the length of the serpentine spring 41, so that the two ends of the regulator are close to the installation positions of the two ends of the serpentine spring 41, punching in the middle of the base 40 is avoided, and the strength of the base 40 is affected. Because furniture adjusting device is provided with electrical components such as motor, and main focus when the people sits at sofa all concentrate in the middle part of serpentine spring 41, the highest department of arch height, when heavier personnel sit down suddenly, serpentine spring 41 can receive great pressure in the moment and make serpentine spring 41 warp down rapidly, if the motor sets up in the middle part of base 40, when receiving great pressure this moment, can collide the motor to make the motor receive the impact damage, if the cushion has the damage, the motor damage can expose the electric wire, then probably can cause personnel's electric shock risk.

The principles and embodiments of the present invention have been described herein with reference to specific examples, the description of which is intended only to facilitate an understanding of the method of the present invention and its core ideas. The foregoing is merely a preferred embodiment of the invention, and it should be noted that, due to the limited text expressions, there is objectively no limit to the specific structure, and that, for a person skilled in the art, modifications, adaptations or variations may be made without departing from the principles of the present invention, and the above technical features may be combined in any suitable manner; such modifications, variations and combinations, or the direct application of the inventive concepts and aspects to other applications without modification, are contemplated as falling within the scope of the present invention.
