Description

Technical Field

[0001] The utility model relates to the technical field of electric bed frames, in particular to a foldable electric bed. Background Art

[0002] Electric beds have become increasingly popular in recent years. The angle between the bed board and the bed frame can change to adapt to the user's different sitting or lying positions. At the same time, in order to prevent the bed board from rising or falling or rotating, which would make the user feel stiff and abrupt, the bed frame will also move relative to the supporting frame when the bed board changes its angle, so that the user can have a more comfortable experience during the posture adjustment process.

[0036] See also Figure 1 , Figure 2 and Figure 3 In some embodiments, a plurality of support beams 65 are mounted on the back panel 51, and one end of the first hinge 63 is fixedly connected to the support beam 65.

[0037] See also Figure 1 , Figure 2 and Figure 5In some embodiments, a second rotating mechanism 7 is further included, wherein the second rotating mechanism 7 includes a second driving member 71, a rotating rod 72, a second driving telescopic rod 73 and a second hinged member 74, wherein the second driving member 71 is assembled on the second bed frame 4, wherein one end of the second driving telescopic rod 73 is connected to the output shaft of the second driving member 71, and the other end of the second driving telescopic rod 73 is hinged to one end of the second hinged member 74, and the other end of the second hinged member 74 is fixedly connected to the rotating rod 72, and both side ends of the rotating rod 72 are fixedly connected with a first rotating support arm 75, wherein one end of the first rotating support arm 75 is hinged to the second bed frame 4, and the other end of the first rotating support arm 75 is hinged with a support plate 76, and the support plate 76 is fixedly connected to the foot plate 55. Optionally, the second driving member 71 can be an electric motor, a motor or a cylinder, etc. Preferably, the second driving member 71 drives the second driving telescopic rod 73 to be extended and retracted, thereby driving the rotating rod 72 to rotate through the second hinge 74, and the first rotating arm 75, driven by the rotating rod 72, drives the foot panel 55 to be lifted or lowered away from one end of the leg panel 54 through the supporting plate 76.

[0038] See also Figure 1 , Figure 2 and Figure 5 In some embodiments, a second rotating arm 77 is hinged between the first rotating arm 75 and the leg panel 54. That is, when the rotating rod 72 drives the first rotating arm 75 to rotate to drive the foot panel 55 to be lifted or lowered, the second rotating arm 77 synchronously drives the leg panel 54 to be lifted or lowered. Specifically, when the foot panel 55 is lifted, the second driving member 71 drives the second driving telescopic rod 73 to extend, driving the second hinged member 74 to drive the rotating rod 72 to rotate, and the first rotating arm 75 and the second rotating arm 77 rotate with the rotating rod 72, thereby lifting the entire foot panel 55 upward, and at the same time, the end of the leg panel 54 close to the foot panel 55 is also lifted upward, forming a posture that is more in line with the human body.

[0039] See also Figure 1 , Figure 2 and Figure 5 In some embodiments, the support sheet 76 is provided with a guide groove, and the first rotating arm 75 is hinged in the guide groove and can slide along the guide groove. Specifically, when the foot plate 55 is raised or lowered, the first rotating arm 75 slides in the guide groove, thereby driving the support sheet 76 to rotate. Compared with the first rotating arm 75 directly driving the support sheet 76 to rotate, such a setting can play a buffering role and optimize the user experience.

[0040] In some embodiments, a receiving groove is provided on the foot panel 55. When the foot panel 55 is in a flat state, the second driving member 71 is received in the receiving groove, thereby preventing the assembly of the driving mechanism from affecting the height and storage of the electric bed and optimizing the overall structure of the electric bed. In this embodiment, the first driving member 61 needs to be removed before folding the first support frame 1 and the second support frame 2 together so that the folded first support frame 1 and the second support frame 2 can be closer together, thereby reducing the space occupied by the electric bed in the storage state and making storage more convenient.

Optionally, the first driving member 61 is assembled on the second supporting frame 2, and the extended first driving telescopic rod 62 drives the back The plate 51 rotates forward around the hinge point between itself and the support rod group 64, so that the back plate 51 is lifted away from one end of the first waist plate 52 to form a backrest. At the same time, the back plate 51 pulls the first waist plate 52 to move horizontally to the rear end, thereby driving the first bed frame 3 to pull the second bed frame 4 and the second waist plate 53, the leg plate 54 and the foot plate 55 on the second bed frame 4 to move horizontally to the rear end, so that the bed board 5 is closer to the wall at the rear end of the electric bed, achieving the effect of "zero leaning against the wall"; further, The second driving member 71 drives the second driving telescopic rod 73 to extend, driving the second hinged member 74 to drive the rotating rod 72 to rotate, and the first rotating support arm 75 and the second rotating support arm 77 rotate along with the rotating rod 72, thereby lifting the entire foot panel 55 upward, and at the same time, the end of the leg panel 54 close to the foot panel 55 is also lifted upward, which is convenient for the user to adjust the height of the legs and feet, so that the user can be in a more comfortable posture; when the electric bed switches from a sitting position to a lying position, the first driving member 61 drives the first driving telescopic rod 73 to extend, driving the second hinged member 74 to drive the rotating rod 72 to rotate, and the first rotating support arm 75 and the second rotating support arm 77 rotate along with the rotating rod 72, thereby lifting the entire foot panel 55 upward, and at the same time, the end of the leg panel 54 close to the foot panel 55 is also lifted upward, so that the user can be in a more comfortable posture. The rod 62 contracts, and the contracted first driving telescopic rod 62 drives the back panel 51 to rotate in the opposite direction around the hinge point between itself and the support rod group 64, so that the back panel 51 moves away from one end of the first waist panel 52 until the back panel 51 is in a flat state. At the same time, the back panel 51 pushes the first waist panel 52 to move forward, thereby driving the first bed frame 3 to push the second bed frame 4 and the second waist panel 53, the leg panel 54 and the foot panel 55 on the second bed frame 4 to move forward;Among them, since the first limiting member 11 and the second limiting member 21 are connected in cooperation to limit the first supporting frame 1 and the second supporting frame 2 to be in the same plane, the first supporting frame 1 and the second supporting frame 2 are ensured to be aligned with each other, and at the same time, the third limiting member 31 and the fourth limiting member 41 are connected in cooperation to limit the first bed frame 3 and the second bed frame 4 to be in the same plane, so that the whole formed by the first bed frame 3 and the second bed frame 4 is more closely fitted with the whole formed by the first supporting frame 1 and the second supporting frame 2, thereby improving the stability of the overall structure of the electric bed, so that the first bed frame 3 and the second bed frame 4 can be smoothly and smoothly translated on the plane formed by the first supporting frame 1 and the second supporting frame 2, effectively avoiding the first supporting frame 1 and the second supporting frame 2 from shaking or dislocation when switching postures, thereby hindering the movement of the first bed frame 3 and / or the second bed frame 4, thereby achieving the smooth and non-stuck state of the electric bed when switching postures, thereby improving the user experience. ;
