Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0032] like Figure 1-6 As shown, a nested folding electric bed is proposed, comprising:

[0033] bedstead;

[0034] The bed board is divided into a head board 3 (rotatably connected to the bed frame), a hip board (fixedly connected to the bed frame), a leg board 6 (rotatably connected to the bed frame), and a foot board 7 (rotatably connected to the leg board 6). The connection method of the bed board is the same as that of the prior art. The bed board is welded together by a steel pipe structure and a plurality of steel wires 14. The steel pipe structure forms the main structure of the bed board and is welded together by a plurality of steel pipes 13. The steel wires 14 are fixed to the supporting side of the steel pipe structure to form the mattress support structure of the bed board. The surface of the bed board is treated by spraying, electrophoresis, etc., and no soft packaging is required. Compared with traditional wooden bed boards, this bed board is lighter, has a simpler surface treatment process, and is lower in cost.

[0035] The foot connecting rod 8 has two ends which are respectively rotatably connected to the foot plate 7 and the bed frame. The leg plate 6, the foot plate 7 and the foot connecting rod 8 form a quadrilateral movable connecting rod mechanism which can move up and down.

[0036] The front motor bracket 10 and the front motor 9 for rotating and supporting the head bed plate 3, the front motor 9 is set as a linear motor, and the two ends of the front motor 9 are respectively connected to the front motor bracket 10 and the head bed plate 3;

[0037] The rear motor bracket 11 and the rear motor 12 for rotating and supporting the leg plate 6 are configured as a linear motor, and the two ends of the rear motor 12 are respectively rotatably connected to the rear motor bracket 11 and the leg plate 6.

[0038] Among them, the front motor bracket 10 and the rear motor bracket 11 can be folded and unfolded to connect to the bed frame. In the packaging state, the front motor bracket 10 and the rear motor bracket 11 are in a folded state. In the use state, the front motor bracket 10 and the rear motor bracket 11 are in an unfolded state and support the ground.

[0039] In use, if Figure 1 、 2 As shown, the front motor bracket 10 is tilted forward based on the connection point, and the rear motor bracket 11 is tilted backward based on the connection point.

[0040] The above-mentioned front motor bracket 10 includes a first main frame and a first support member 10c. One end of the first main frame is connected to the bed frame for vertical rotation, and the other end supports the ground when unfolded. The two ends of the first support member 10c are respectively connected to the first main frame and the bed frame to fix the unfolded position of the first main frame.

[0041] The first main frame of the above-mentioned front motor bracket 10 is set as a C-shaped rod structure, which is composed of two first side rods 10a distributed on the left and right and a first bottom rod 10b fixedly connected to the bottom of the two first side rods 10a. The first bottom rod 10b is close to the ground when the front motor bracket 10 is unfolded, and the front motor 9 is rotated to be connected to the first bottom rod 10b and uses the first bottom rod 10b as the bottom support base. When the bed board is flattened, the inclination angle of the front motor 9 is similar to the inclination angle of the first side rod 10a. One end of the first side rod 10a is rotated to be connected to the bed frame, and the other end is fixedly connected to the first bottom rod 10b. The first support member 10c is set as a connecting rod, and two are provided, and respectively correspond to the two first side rods 10a. The two ends of the first support member 10c are respectively connected to the bed frame and the first side rod 10a. One end of the first support member 10c is rotated to be connected to the bed frame, and the other end is detachably connected to the first side rod 10a through a fastener.

[0042] Seen from a side perspective, the front motor bracket 10 forms a tripod structure, thereby creating a stable supporting effect.

[0043] The above-mentioned rear motor bracket 11 includes a second main frame and a second support member 11c. One end of the second main frame is connected to the bed frame for vertical rotation, and the other end supports the ground when unfolded. The two ends of the second support member 11c are respectively connected to the second main frame and the bed frame to fix the unfolded position of the second main frame.

[0044] The second main frame of the above-mentioned rear motor bracket 11 is set as a C-shaped rod structure, which consists of two second side rods 11a distributed on the left and right and a second bottom rod 11b fixedly connected to the bottom of the two second side rods 11a. The second bottom rod 11b is close to the ground when the rear motor bracket 11 is unfolded, and the rear motor 12 is rotated to connect to the second bottom rod 11b and use the second bottom rod 11b as the bottom support base. When the bed board is flattened, the inclination angle of the rear motor 12 is similar to the inclination angle of the second side rod 11a. One end of the second side rod 11a is rotated to connect to the bed frame, and the other end is fixedly connected to the second bottom rod 11b. The second support member 11c is set as a connecting rod, and two are provided, and respectively correspond to the two second side rods 11a. The two ends of the second support member 11c are respectively connected to the bed frame and the second side rod 11a. One end of the second support member 11c is rotated to connect to the bed frame, and the other end is detachably connected to the second side rod 11a through a fastener.

[0045] Principle of whole bed movement:

[0046] When in use, the front motor bracket 10 and the rear motor bracket 11 are folded downward and unfolded, and the unfolded position of the front motor bracket 10 is fixed by the first support member 10c, and the unfolded position of the rear motor bracket 11 is fixed by the second support member 11c, forming a triangular support structure between the front frame 1 and the rear frame 2, making the support effect more stable;

[0047] One end of the front motor 9 is connected to the front motor bracket 10, and the other end is rotatably connected to and supports the head bed board 3. Through the extension and contraction of the front motor 9, the head bed board 3 is driven to rotate along its hinge axis (the hinge rod 15 rotates to connect the support hinge seat 16) to complete the head lifting action.

[0048] One end of the rear motor 12 is connected to the rear motor bracket 11, and the other end is rotatably connected to and supports the leg plate 6. Through the extension and contraction of the rear motor 12, the leg plate 6 is driven to rotate along the hinge axis, driving the leg plate 6, the foot plate 7 and the foot connecting rod 8 to move up and down, completing the lifting and lowering action of the foot.

[0049] The resulting advantages are:

[0050] 1. The bed plate is directly driven by the motor, making the structure simpler and the material cost lower;

[0051] 2. The unfolded front / rear motor brackets enable the front / rear motors to have a larger driving angle, save more effort, and have lower requirements on materials and motors;

[0052] 3. Compared with traditional electric beds, the distance between the hinge axis of the head bed board 3 and the leg board 6 of this design and the bed board support surface is increased, so that the pushing angle of the front motor 9 and the rear motor 12 is larger, which is more conducive to the front motor 9 and the rear motor 12 to apply thrust.

[0053] like Figure 4-6 As shown, the above-mentioned bed frame is divided into a front frame body 1 and a rear frame body 2, and the front frame body 1 and the rear frame body 2 are connected in a foldable and unfoldable manner. Accordingly, the front motor bracket 10 is connected to the front frame body 1, and the rear motor bracket 11 is connected to the rear frame body 2. The buttocks board is divided into a front buttocks board 4 and a rear buttocks board 5 at the connection position between the front frame body 1 and the rear frame body 2, and the front buttocks board 4 and the rear buttocks board 5 are separated from each other; when packed, the bed frame is in a folded form, and the front frame body 1 and the rear frame body 2 are nested with each other to reduce the packaging height. At this time, the upper and lower bed board surfaces are parallel to each other, as shown in FIG. Figure 4 As shown, the rear hip board 5, the leg board 6 and the foot board 7 are on the same side, and the front hip board 4 and the head bed board 3 are on the other side.

[0054] More specifically, the width of the rear frame 2 is smaller than the width of the front frame 1. When packaging, the rear frame 2 is located on the inner side of the front frame 1, so that the folded bed frame partially overlaps in the height direction, thereby obtaining a smaller packaging height of the entire bed, reducing packaging and transportation costs, and the entire bed can meet the specified transportation requirements.

[0055] A hinge rod 15 is provided at the rotation fulcrum of the above-mentioned head bed board 3 / leg board 6, and a support hinge seat 16 is fixedly connected to the corresponding position on the lower side of the bed frame. One end of the hinge rod 15 is fixedly connected to the head bed board 3 / leg board 6, and the other end thereof is rotatably connected to the support hinge seat 16, and the rotation connection point between the hinge rod 15 and the support hinge seat 16 is below the bed frame. In the initial state of the bed board being flattened, the hinge rod 15 is tilted, so that the rotation fulcrum of the head bed board 3 / leg board 6 is below the bed frame, which is beneficial for the front motor 9 and the rear motor 12 to apply thrust.
