[0037] The following is a description of the preferred embodiments of the present utility model in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only for explaining and illustrating the present utility model, and are not used to limit the present utility model.

[0038] As Figures 1 to 7 shown, a light and thin lifting bed frame structure includes a middle bracket 1. One side of the middle bracket 1 is hinged to the first lifting bracket 2, and the other side of the middle bracket 1 is hinged to the second lifting bracket 3; both the left and right sides below the middle bracket 1 are connected with mounting rods 11. In actual application, support feet can be added below the mounting rods 11, or the mounting rods 11 can be fixed to an external base to support the entire light and thin lifting bed frame structure for use.

[0039] A fixed member 4 is connected below the middle bracket 1. One side of the fixed member 4 is hinged to the first driver 5, and the first driver 5 is hinged to the first lifting bracket 2. The first driver 5 is used to drive the lifting of the first lifting bracket 2; the other side of the fixed member 4 is hinged to the second driver 6, and the second driver 6 is hinged to the second lifting bracket 3. The second driver 6 is used to drive the lifting of the second lifting bracket 3; specifically, the fixed member 4 is a pair of clamping plates. The lugs on the base of the first driver 5 are clamped and hinged to one side of the pair of clamping plates, and the lugs on the base of the second driver 6 are clamped and hinged to the other side of the pair of clamping plates. This clamping and hinging method can enhance the stability of the connection between the first driver 5, the second driver 6 and the fixed member 4.

[0040] In this embodiment, the first drive 5 and the second drive 6 are both electric push rods; the second lifting bracket 3 includes an active frame body 301 and a passive frame body 302. The middle bracket 1 is hinged to the active frame body 301, and the active frame body 301 is hinged to the passive frame body 302; the push rod of the first drive 5 is hinged to the first lifting bracket 2, and the push rod of the second drive 6 is hinged to the passive frame body 302. When the push rods of the first drive 5 and the second drive 6 retract, the first lifting bracket 2 and the second lifting bracket 3 are in the flat state as shown in Figure 7 ; when the push rods of the first drive 5 and the second drive 6 extend, the first lifting bracket 2 and the second lifting bracket 3 are in the raised state as shown in Figure 3 . For the lifting mode of the second lifting bracket 3, the second drive 6 directly pushes the active frame body 301 to rotate, and the active frame body 301 drives the passive frame body 302 to rotate.

[0041] From Figure 2 and Figure 3 view, rotating support arms 10 are arranged on both the left and right sides below the second lifting bracket 3. Specifically, one end of the rotating support arm 10 is hinged to the middle bracket 1, and the other end of the rotating support arm 10 is hinged to the passive frame body 302. When the second lifting bracket 3 moves up and down, the rotating support arm 10 plays a role of supporting and pulling the passive frame body 302 to prevent the passive frame body 302 from swinging randomly.

[0042] Plate members 7 are connected to the lower bottom surfaces of the first lifting bracket 2 and the active frame body 301 respectively. Connecting members 8 are arranged on the plate members 7 and are fixedly connected to the plate members 7. The push rods of the two electric push rods are respectively hinged to the corresponding connecting members 8; the plate members 7 are plate-shaped, increasing the fixing area with the lower bottom surfaces of the first lifting bracket 2 and the active frame body 301 and improving the fixing strength; the plate members 7 can be fixed to the first lifting bracket 2 and the active frame body 301 by welding or bolting.

[0043] As shown in Figure 6 , a support member 9 is arranged on the plate member 7. One side edge of the support member 9 is connected to the plate member 7, and the adjacent side edge of the support member 9 is connected to the connecting member 8; in this embodiment, the two adjacent sides of the support member 9 are respectively welded to the plate member 7 and the connecting member 8; the support member 9 is located on the side of the connecting member 8 away from the electric push rod, so the support member 9 can enhance the connecting member 8's ability to bear the thrust of the electric push rod and improve the structural strength.

[0044] As shown in Figure 2 and Figure 5As shown, the first lifting bracket 2 and the second lifting bracket 3 are connected to the bottom with supporting legs 12. When the first lifting bracket 2 and the second lifting bracket 3 are in a flat state, the supporting legs 12 are overlapped on the mounting rod 11; in the flat state, the supporting legs 12 support the first lifting bracket 2 and the second lifting bracket 3; the upper surfaces of the middle bracket 1, the first lifting bracket 2 and the second lifting bracket 3 are all provided with a plurality of load-bearing rods 14, and the load-bearing rods 14 are staggered and connected to help enhance the overall load-bearing effect; as shown in FIG. Figure 7 As shown, when the first lifting bracket 2 and the second lifting bracket 3 are in a flat state, the upper surfaces of the first lifting bracket 2, the second lifting bracket 3 and the middle bracket 1 are flat, which is conducive to laying the mattress flatly.

[0045] In addition, side frames 13 are provided on the left and right sides of the middle bracket 1, the first lifting bracket 2, and the second lifting bracket 3; the adjacent side frames 13 are arranged to form arc angles 1301 at the opposite sides; when laying the mattress, the two sides of the mattress are wrapped in the side frames 13 for fixation, and in the process of lifting and lowering the first lifting bracket 2 and the second lifting bracket 3, the position of the arc angle 1301 of the side frame 13 will also rotate. If this part is a sharp angle, it is easy to scratch the edge of the mattress. Therefore, it is designed to be an arc angle to avoid the edge of the mattress being scratched.

[0046] The improvement of the present invention lies in that, in the horizontal projection area, the first driver 5, the fixing member 4 and the second driver 6 are connected in a straight line, which makes the structure compact. Figure 1 as well as Figure 2 It can be seen that the fixing member 4 is in the shape of an elongated plate, which can be connected to the bottom of the load-bearing rod 14 in the middle position of the middle bracket 1 to achieve the purpose of hiding; and the fixing member 4 is located in the middle position between the first driver 5 and the second driver 6. Therefore, when the first driver 5 and the second driver 6 work at the same time, the forces acting on the fixing member 4 from the first driver 5 and the second driver 6 can be partially offset, thereby achieving the effect of reducing the force on the middle bracket 1.

[0047] In the vertical projection area, the first driver 5, the second driver 6 and the side frame 13 partially overlap; Figure 3 as well as Figure 7 For example, when viewed from the side, the side frame 13 partially blocks the first driver 5 and the second driver 6, that is, in this embodiment, the first driver 5 and the second driver 6 are arranged close to the bottom of the first lifting bracket 2 and the second lifting bracket 3. This structure is also different from the traditional lifting bed frame in which the driver is suspended. The driver is suspended, which makes the overall lifting bed frame heavier; while in the present embodiment, this design makes the lifting bed frame structure thinner; the thin lifting bed frame structure in this embodiment is used as a frame for an integrated or embedded mattress.

[0048] As shown Figure 1 , Figures 8 to 9 shown, hinge members 15 are provided between the middle bracket 1 and the first lifting bracket 2, and between the middle bracket 1 and the second lifting bracket 3; the hinge member 15 includes a first rotating shaft seat 1501 and a second rotating shaft seat 1502; taking the middle bracket 1 and the first lifting bracket 2 as an example, the first rotating shaft seat 1501 or the second rotating shaft seat 1502 is welded to the middle bracket 1, and the second rotating shaft seat 1502 or the first rotating shaft seat 1501 is welded to the first lifting bracket 2, so that the first rotating shaft seat 1501 and the second rotating shaft seat 1502 are used in a matching manner; copper sleeves 1504 are installed on both sides of the second rotating shaft seat 1502; as can be seen from Figure 9 , openings are provided in the lugs on both sides of the first rotating shaft seat 1501. After inserting the bolt 1505 through the openings and the copper sleeves 1504 from one side, a nut 1506 is screwed on the end to connect the first rotating shaft seat 1501 and the second rotating shaft seat 1502 into one body, so that the middle bracket 1 and the first lifting bracket 2 are in a hinged state. The connection between the middle bracket 1 and the second lifting bracket 3 is the same as the above connection method and will not be elaborated here. Since the first rotating shaft seat 1501 and the second rotating shaft seat 1502 are generally made of iron or stainless steel, there will be relatively large noise when they are directly in contact during rotation. In this structure, by arranging the copper sleeves 1504 at the contact part between the first rotating shaft seat 1501 and the second rotating shaft seat 1502, because the hardness of copper is less than that of iron and stainless steel, the noise can be eliminated and a certain sound absorption effect can be achieved. In this embodiment, the copper sleeve 1504 is a powder metallurgy copper sleeve.

[0049] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
