Cushion with switchable bearing parts and switching control method

Abstract

The invention relates to a cushion with switchable bearing parts and a switching control method. The temperature of conventional cushions with switchable bearing parts cannot be uniformly controlled. The cushion with switchable bearing parts in the invention comprises a cushion (42); the cushion is connected with a control unit (40) via a pipeline; the control unit is connected with a medium box (16) via a pipeline; the cushion comprises a base plate (2); the base plate is provided with an inlet-and-outlet pipe A (6) and an inlet-and-outlet pipe B (7); the inlet-and-outlet pipe A is communicated with coating films on or lining capsules of a group of grooves A (3) to form a cavity; the inlet-and-outlet pipe B is communicated with coating films on or lining capsules of a group of grooves B (4) to form another cavity; and the soft films on the grooves are separately connected with the ends of the grooves A and the grooves B. The invention discloses the cushion with switchable bearing parts and the switching control method.

Description

[0001] Technical field:

[0002] The invention relates to a cushion capable of transforming a load-bearing part and a transform control method.

[0003] Background technique:

[0004] The present cushion with convertible load-bearing parts has many disadvantages such as large volume, heavy weight, complex structure, high price, inconvenient installation, poor elasticity of the cushion, and uneven temperature control.

[0005] Invention content:

[0006] The object of the present invention is to provide a cushion with convertible load-bearing parts and a conversion control method.

[0007] Above-mentioned purpose realizes by following technical scheme:

[0008] A cushion with a convertible load-bearing part, which comprises: a cushion, the cushion is connected to a control device through a pipeline, the control device is connected to a medium tank through a pipeline, the cushion includes a bottom plate, and the There are inlet and outlet pipes A and B respectively on the base...
