Description

Technical Field

[0001] This utility model relates to the technical field of furniture, and in particular to an electric lifting bed. Background Technology

[0002] With the improvement of people's living standards, electric beds have become widely used. Generally, an electric bed consists of multiple hinged panels, with a bed frame underneath. A motor drives the panels to rise and fall, allowing users to change positions while lying down. However, because the bed frame is usually assembled using bolts, its position cannot be changed once it's assembled. This limits users to a few specific lying positions, resulting in limited functionality that fails to meet the diverse needs of the market. Summary of the Invention

[0003] To address the aforementioned technical problems, this utility model provides an electric lifting bed. The specific technical solution is as follows:

[0004] An electric lifting bed is provided, comprising a support base frame, a first lifting assembly, a second lifting assembly, an outer frame, and a bed frame structure. The support base frame has opposing first and second sides, and a first and second sliding groove located between the first and second sides. The first and second sliding grooves are symmetrical about the centerline of the support base frame, with the first sliding groove closer to the first side than the second sliding groove. The first lifting assembly is mounted on the support base frame and includes a first electric push rod and a first lifting support arm. The first electric push rod is connected to the first lifting support arm, and the upper end of the first lifting support arm has a pivot member. The lower end of the first lifting support arm is slidably disposed within the first sliding groove. The second lifting assembly is mounted on the support base frame and includes a second electric push rod and a second lifting support arm. The second electric push rod is connected to the second lifting support arm, and the lower end of the second lifting support arm is slidably disposed within the second sliding groove. The outer frame is set above the supporting base. The upper end of the first lifting support arm is pivotally connected to the outer frame through a pivoting component. The upper end of the first lifting support arm is pivotally connected to one end of the outer frame. The first lifting support arm is inclined and its upper end is closer to the first side than its lower end. The other end of the outer frame is provided with a third sliding groove. The upper end of the second lifting support arm is slidably set in the third sliding groove. The second lifting support arm is inclined and its upper end is closer to the second side than its lower end.

[0005] In one embodiment, the support base includes a rectangular main frame, a first support rod and a second support rod. The first side and the second side are located on both sides of the length direction of the rectangular main frame. The two ends of the first support rod and the second support rod are respectively located in the length direction of the support base. The first slide groove and the second slide groove are located between the first support rod and the second support rod. The first slide groove is closer to the first support rod than the second slide groove.

[0006] In one embodiment, the first electric push rod has its setting end pivotally connected to the second support rod, and its driving end pivotally connected to the bottom of the first lifting support arm. The first electric push rod is configured to drive the lower end of the first lifting support arm to slide in the first slide groove and drive the upper end of the first lifting support arm to rotate relative to the outer frame. The second electric push rod has its setting end pivotally connected to the first support rod, and its driving end pivotally connected to the bottom of the second lifting support arm. The second electric push rod is configured to drive the lower end of the second lifting support arm to slide in the second slide groove and drive the upper end of the second lifting support arm to slide in the third slide groove.

[0007] In one embodiment, the first lifting assembly further includes a first slider, and a support base is provided with a first opening corresponding to the first slider at a corresponding position in the second slide groove. The first slider is placed in the first slide groove through the first opening, and the lower end of the first lifting support arm is pivotally connected to the first slider. The first lifting support arm is slidably disposed in the first slide groove through the first slider. The second lifting assembly further includes a second slider, and a support base is provided with a second opening corresponding to the second slider at a corresponding position in the second slide groove. The second slider is placed in the second slide groove through the second opening, and the lower end of the second lifting support arm is pivotally connected to the second slider. The second lifting support arm is slidably disposed in the second slide groove through the second slider.

[0008] In one embodiment, when the upper end of the second lifting support arm is located in the middle section of the third slide, the outer frame is parallel to the support base. When the upper end of the second lifting support arm slides toward the end of the third slide away from the first side and the upper end of the first lifting support arm rotates from top to bottom, the outer frame is tilted toward the first side relative to the support base. Alternatively, when the upper end of the second lifting support arm slides toward the end of the third slide away from the first side, the outer frame is tilted toward the second side relative to the support base.

[0009] In one embodiment, the first lifting assembly further includes a first lifting link, one end of which is pivotally connected to a support base frame inside the first support rod on the first side, and the other end of which is pivotally connected to a first lifting support arm.

[0010] In one embodiment, the second lifting assembly further includes a second lifting link, one end of which is pivotally connected to the support base frame inside the second support rod on the second side, and the other end of which is pivotally connected to the second lifting support arm.

[0011] In one embodiment, the system further includes a bed frame structure disposed on the outer frame. The bed frame structure includes an upper body frame, a hip frame, a leg frame, and a foot frame connected in sequence. The side of the upper body frame adjacent to the hip frame is connected to the outer frame. The hip frame is fixed to the outer frame. The side of the leg frame adjacent to the hip frame is pivotally connected to the outer frame. The side of the leg frame away from the hip frame is pivotally connected to the leg frame.

[0012] In one embodiment, the bed frame structure further includes a first drive member and a lifting frame. One end of the lifting frame is pivotally connected to the outer frame and its pivot point is located on the side of the upper body frame close to the hip frame. The other end of the lifting frame is slidably connected to the side of the upper body frame away from the hip frame. The first drive member is connected to the lifting frame and is configured to drive the lifting frame to rotate, thereby causing the upper body frame to rotate upward relative to the hip frame.

[0013] In one embodiment, the bed frame structure further includes a second drive member, the drive end of which is connected to the leg frame. The second drive member is configured to drive the leg frame to rotate upward relative to the hip frame and to drive the foot frame to rotate relative to the leg frame.

[0014] In this embodiment of the utility model, the first electric push rod of the first lifting assembly can drive the first lifting support arm to rotate, thereby causing the upper end of the second lifting support arm to slide in the third slide groove. Alternatively, the second electric push rod of the second lifting assembly can drive the second lifting support arm to rotate, thereby causing the upper end of the second lifting support arm to slide in the third slide groove. This adjusts the tilt direction of the outer frame relative to the support base, thereby adjusting the tilt direction of the bed frame structure to meet the diverse needs of users for the tilt function of the electric lifting bed.
