Description

Technical Field

[0001] The utility model relates to the field of sofa beds, in particular to a zero-gravity sofa bed. Background Art

[0002] Zero gravity sofa bed refers to switching the sofa to bed mode, and supporting the neck and legs through footrests and neck supports, so as to achieve the sense of suspension (i.e. zero gravity) transmitted to the brain. This structure has better comfort and can effectively improve the relaxation of the human body.

[0003] However, in the process of moving, the existing sofa bed generally adopts a horizontal slider arranged on the base, and a hinged rod is arranged between the horizontal slider and the lumbar support and the leg support, so as to realize the relative swing of the lumbar support and the leg support. In the actual operation of this structure, if one of the horizontal sliders is damaged, it is easy to make abnormal noise or slide unsmoothly, which affects the smooth switching between the sofa and the bed and affects the user experience.

[0004] At the same time, the structure includes a guide rail and a slider (or a guide rod and a sliding sleeve) and a motor (which can be a screw pair and a rotating motor or a telescopic motor). The structure is relatively complex and the production cost is also high. Utility Model Content

[0005] The main purpose of the utility model is to provide a zero-gravity sofa bed, aiming to improve the bed frame structure of the existing sofa bed, thereby simplifying the internal structure, achieving a linear transition between the sofa and the bed, and improving the user experience.

[0006] To achieve the above object, the utility model provides a zero-gravity sofa bed, comprising:

[0007] A main frame, wherein the main frame is a long strip-shaped frame;

[0008] A positioning frame, which is arranged in the middle of the main frame and is fixedly disposed;

[0009] A leg bracket, the leg bracket is arranged at an upper position on the left side of the main frame, and the right side of the leg bracket is pivotally connected to the positioning frame, and a first driving device is arranged between the leg bracket and the main frame, and the first driving device is used to drive the leg bracket to swing in a predetermined manner;

[0010] The body support is arranged at an upper position on the right side of the main frame, and the left side of the body support is pivotally connected to the positioning frame. A second driving device is arranged between the body support and the main frame, and the second driving device is used to drive the body support to swing in a predetermined manner. (The pivotal connection end of the leg support and the body support can also be the main frame, but the positioning frame is mainly provided to make the upper wall of the sofa appear flush when used as a sofa.)

[0011] In actual use, when the leg support and the body support are flush with the main frame, the outer pads on the three make it a flush sofa; when sleeping is needed, the leg support and the body support are set to a predetermined swing amplitude through the setting of the first drive device and the second drive device, and then switched to a curved bed, thereby supporting the legs and the head, effectively improving the comfort, and achieving a sensory zero-gravity experience.

[0012] At the same time, in terms of mechanical stability, the first driving device and the second driving device are used to directly drive the movement of the push bracket and the body bracket, which reduces the use of the guide structure, makes the structure simpler, and reduces the production cost, effectively improving the market competitiveness.

[0024] A main frame 1, wherein the main frame is a long strip-shaped frame;

[0025] A positioning frame 11, wherein the positioning frame 11 is arranged in the middle of the main frame 1 and is fixedly disposed;
