Description

Adjustable mattress with stable configuration

The present invention relates to the field of mattress technology, and more particularly to a mattress with a stable construction.

The mattresses that people use today are basically all lying flat on the bed, fixed and not moving, and only providing a comfortable sleeping posture for people. However, people's demands for mattresses are not limited to this. For example, if people sit on their beds reading books or watching TV, I hope they can build mattresses so people can rest on their beds. However, the conventional mattress has a single function and can not satisfy people's use demands.

The design according to the conventional utility model registration application with the application number CN201520789176.X, registered on March 9, 2016, designation "electric invisible mattress" includes an electric bed frame, The bed frame is wrapped in a mat to form a mattress. The bed frame includes a fixed frame at the center, a bed tail frame connected to one end of the fixed frame via at least two connecting rods, and a bed head frame Wherein the first linear motor and the second linear motor are connected to the fixed frame, the driving shaft of the first linear motor is connected to the bed tail frame through a connecting rod, and is driven to raise and lower horizontally, 2 The drive shaft of the linear motor is connected to the bed head frame and drives it to center the hinge connection point The swing. The design according to the application is suitably foldable for convenient use by the user. However, the design according to this application has the following further problems.

(1) The rotation of the bed head frame is completed by the second connecting plate in which the second linear motor is fixed to the bed head frame, and the driving shaft end of the second linear motor is hinged to the second connecting plate. However, such a driving method is not stable in operation, and the pressure is concentrated on the hinge connection points of the second connection plate and the drive shaft, so that the second connection plate is very easily broken.

(2) When the bed head frame is rotated by directly hinging between the fixed frame at the center portion and the bed head frame, the angle formed between the bed head frame and the fixed frame is relatively small. At this time, since the waist portion of the human body is floating in the air, it can not lean on the mattress, which greatly affects the comfort of the user leaning and is harmful to the human skeletal health.

(3) The fixed frame and the bedtail frame in the middle portion are connected through two connecting rods, and the first connecting plate, the upper connecting rod, the lower connecting rod and the bedtail frame form a parallelepiped structure. However, the parallelogram structure is very unstable. When the operation time is long, the connection between the first connecting plate, the upper connecting rod, the lower connecting rod and the bedtail frame is loosened, noise is generated, and even structural damage occurs .

The object of the present invention is to overcome the above-described problems existing in conventional mattresses, and provide a stable mattress with a stable configuration.
