Description

Technical Field

[0001] The utility model relates to a mattress with adjustable softness, hardness and elasticity, belonging to the technical field of mattresses. Background Art

[0002] As people's living standards continue to improve, consumers' demands for mattresses are becoming increasingly diverse. They pursue not only comfort, but also hope to be able to make personalized adjustments based on their physical condition and sleeping habits. However, most mattresses on the current market still have some shortcomings. Most mattresses have relatively single functions, and once they are produced, their softness and hardness are fixed, making it difficult to flexibly adjust them according to different groups of people or different needs. To this end, the industry has developed a variety of mattresses. For example, the Chinese utility model patent with authorization announcement number CN209090488U discloses a mattress with adjustable softness and hardness, and specifically discloses a rectangular frame and a mattress core formed by a plurality of mattress springs arranged inside the rectangular frame. The mattress core is arranged inside the rectangular frame, and an adjustment plate is also provided inside the rectangular frame. The adjustment plate is provided with spring holes corresponding to the mattress springs, and the mattress springs all pass through the spring holes. An adjustment spring is fixed on the upper surface of the adjustment plate, and an adjustment device for controlling the up and down movement of the adjustment plate is provided at the bottom of the adjustment plate. In this solution, the hardness of the mattress is adjusted by moving the adjustment spring. However, when adjusting the hardness, each adjustment device needs to be adjusted once, which is time-consuming and labor-intensive. Moreover, it is difficult to accurately ensure that the heights of the adjustment devices are at the same level after adjustment, which can easily cause the mattress to be uneven and have different hardnesses.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In the present invention, when the mattress needs to be firmer, the steel wire in the driving mechanism of the lifting mechanism is tightened and contracted. As the steel wire passes from the bottom of the roller to the top of the pulley, it exerts an upward force on the roller. With the cooperation of the slider and the slide groove, the lifting seat is finally moved upward. The lifting seat drives the first bed board upward along the guide rod. As the distance between the first and second bed boards decreases, the spring is compressed, thereby hardening the mattress. If the bed board needs to be softened, the motor is reversed to slowly unwind the steel wire in the winding drum. At the same time, the weight of the human body and the second bed board presses the lifting seat downward, increasing the distance between the first and second bed boards, and the spring slowly recovers, thereby softening the mattress. Thus, the present invention can adjust the hardness of the mattress and improve comfort, and has the advantage of being able to meet the hardness requirements of various users.

Considering that everyone has different preferences for heat and cold, the heated bed 7 is equipped with two body heating zones 9, allowing both people lying on the mattress to stay warm at the appropriate temperature. Furthermore, the heating wires 18 in the body, hand, leg, and head heating zones 11, 12 can be activated to provide targeted heating, according to their individual needs, for a more comfortable sleep.

[0027] Working principle:

[0028] When the mattress needs to be harder, the motor 28 of the driving mechanism 20 in the lifting mechanism 2 makes the rotating shaft 29 rotate, so that the winding drum 30 tightens and contracts the steel wire 31. As the steel wire 31 passes from the bottom of the roller 26 to the top of the pulley 22 and is wound out, the steel wire 31 exerts an upward force on the roller 26. With the cooperation of the slider 24 and the slide groove 25, the lifting seat 23 is finally moved upward, and the lifting seat 23 drives the first bed board 3 to move upward along the guide rod 6. As the distance between the first bed board 3 and the second bed board 5 becomes smaller, the spring 4 is compressed, thereby making the mattress harder; if the bed board needs to be softened, the motor 28 is reversed to make the steel wire 31 in the winding drum 30 slowly wind out. At the same time, due to the weight of the human body and the second bed board 5, the lifting seat 23 is pressed downward, increasing the distance between the first bed board 3 and the second bed board 5, and the spring 4 slowly recovers, thereby making the mattress softer.
