Description

Technical Field

[0001] The utility model belongs to the technical field of electric mattresses, and in particular relates to an iron frame of an electric mattress. Background Art

[0002] There are only two types of electric mattresses on the market. One is semi-wrapped, that is, the bed frame and motor are exposed outside and the mattress is wrapped separately; the other is that the bed frame and motor are completely wrapped in the mattress.

[0003] According to the relevant technology, an electric mattress can be divided into two-partition, three-partition, and four-partition. For example, a four-partition mattress includes: a supporting bottom frame, a head frame, a hip frame, a leg frame, and a foot frame. In a four-partition electric mattress, the driver drives the leg frame to rotate to adjust the posture of the mattress. During the rotation of the leg frame, a linkage rod will be configured for the foot frame in order to make the foot frame work in conjunction. The linkage rod needs to be connected to the supporting bottom frame.

[0004] However, the above structure is only suitable for a semi-wrapped mattress, and is not suitable for a fully wrapped electric mattress with four partitions, because the linkage rod and the supporting bottom frame will be exposed to the outside.

[0005] Therefore, it is necessary to design an iron frame that is applicable to a fully wrapped electric mattress. Utility Model Content

[0006] In order to solve the technical problems mentioned in the background technology, the utility model provides an iron frame of an electric mattress, which includes: a supporting bottom frame; and a mattress frame, which includes: a hip frame, a leg frame and a foot frame, the hip frame is arranged on the supporting bottom frame, the leg frame is hinged at the rear of the hip frame, the foot frame is hinged at the rear of the leg frame, and a plurality of torsion springs are arranged between the leg frame and the foot frame; and a leg driving mechanism, one end of which is hinged to the hip frame and the other end is hinged to the leg frame, suitable for driving the leg frame to adjust the posture; wherein the thickness range of the mattress frame is 100mm to 140mm; the thickness range of the supporting bottom frame is 20mm to 35mm.

[0007] Furthermore, the ratio of the length of the hip frame to the length of the supporting bottom frame ranges from 0.4 to 0.5.

[0008] Furthermore, the ratio of the width of the supporting bottom frame to the width of the hip frame is in a range of 0.7 to 0.8.

[0009] Furthermore, a pair of first push rod iron sheets are provided in the middle of the leg frame in the width direction; and the other end of the leg driving mechanism is hinged to the first push rod iron sheet.

[0010] Furthermore, a head frame is hingedly connected to the front of the hip frame; a head driving mechanism is hingedly connected to the hip frame, and a driving end of the head driving mechanism is hingedly connected to the head frame.

[0011] Furthermore, a pair of second push rod iron sheets are provided in the middle of the head frame in the width direction; and the driving end of the head driving mechanism is hinged to the second push rod iron sheets.

[0012] Furthermore, the rotation range of the head frame is 0° to 65°.

[0013] Furthermore, the rotation range of the leg frame is 0° to 50°.

[0014] The beneficial effect of the utility model is that the iron frame of the electric mattress drives the foot frame and the leg frame to be linked through the torsion spring, replacing the exposed linkage rod in the prior art, thereby greatly increasing the wrapping of the fully wrapped electric mattress. At the same time, the thickness of the supporting bottom frame is set very thin to reduce the presence of the supporting bottom frame in the field of vision.
