Detailed Implementation

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0012] like Figure 1 and Figure 2 As shown, the front lower care bed provided in this embodiment is mainly divided into four layers, which are: bed board assembly 1, inner frame assembly 2, outer frame assembly 3 and bed leg assembly 4 from top to bottom; the bed board assembly 1 is movably mounted on the inner frame assembly 2, the outer frame assembly 3 is slidably connected to the inner frame assembly 2, and the bed leg assembly 4 is fixed to the lower surface of the outer frame assembly 3.

[0013] like Figure 1 and Figure 8 As shown, in this embodiment, the bed board assembly 1 is composed of five independent bed boards rotatably connected, defined as: back assembly 11, lumbar assembly 12, hip assembly 13, leg assembly 14, and foot assembly 15. The tail end of the hip assembly 13 is rotatably connected to the inner frame assembly 2.

[0014] like Figure 7 As shown, in this embodiment, the inner frame assembly 2 is a rectangular structure composed of four square tubes. An inner vertical tube 21 is located on the back of the inner frame assembly, approximately below the hip assembly. The tail of the inner frame assembly is located below the leg assembly. Rollers 22 are provided at the four corners of the inner frame assembly, and a pair of rollers 22 are positioned between the inner vertical tube 21 and the tail of the inner frame assembly 2. A first connecting rod 23 is provided between the head of the inner frame assembly 2 and the inner vertical tube. Specifically, as shown... Figure 4 , Figure 9 and Figure 10 As shown, the first connecting rod 23 is positioned close to the inner vertical tube 21. One end of the first connecting rod 23 is movably connected to the inner frame assembly 2. Specifically, one end of the first connecting rod 23 has an inclined sliding groove 231, and the other end of the first connecting rod 23 is rotatably connected to the front end of the hip assembly 13. Figure 3 , 4 As shown in Figures 5 and 9, this embodiment also includes a first driving component, which is a first motor 5. The fixed end of the first motor 5 is fixed to the inner vertical tube 21, and the driving end of the first motor 5 acts on the back assembly 11, specifically at the tail end of the back assembly 11. It also includes a second motor 6, the fixed end of which is fixed to the inner vertical tube 21, and the driving end of the second motor 6 acts on the tail end of the outer frame assembly 3.

[0015] like Figure 6As shown, in this embodiment, the outer frame assembly 3 is also a rectangular structure composed of four square tubes. At the four inner corners of the outer frame assembly 3, there are grooves 31 that cooperate with the rollers 22. Each groove 31 has an opening 311, the length of which is shorter than the length of the groove. The openings 311 of the two grooves 31 located at the front end of the outer frame assembly are located at the rear end of the groove 31, while the openings of the two grooves 31 located at the rear end of the outer frame assembly 3 are located at the front end of the groove 31. A pair of second connecting rods 32 are provided at the rear end of the outer frame assembly 3. One end of each second connecting rod 32 is fixed to the rear end of the outer frame assembly 3, and the other end is rotatably connected to the foot assembly 15.

[0016] like Figures 3 to 5 As shown, when the first motor actuates, it lifts or flattens the backrest assembly. Simultaneously, when the second motor actuates, it moves the bed board assembly forward, pushing the hip assembly up due to the first linkage. Likewise, when the second motor actuates, it moves the bed board assembly backward, flattening the hip assembly. Therefore, this embodiment achieves coordinated adjustment of the backrest and hip angles, pushing the bed forward and flattening the bed surface. Furthermore, the bed frame of this embodiment is packaged in separate parts, allowing for quick disassembly and transportation, reducing packaging volume for convenient home use, and assisting users in getting in and out of bed.
