The embodiments described below by referring to the drawings are exemplary and are only used to explain the present patent, and cannot be understood as a limitation of the present patent.

[0081] As Figure 1 , Figure 2As shown in the figure, a detachable flexible bed board electric bed comprises: a first driving mechanism 1, a second driving mechanism 2; a first bed board 3, a second bed board 4; a first frame mechanism 5, a second frame mechanism 8; the first bed board 3 is arranged on the first frame mechanism 5, and the second bed board 4 is arranged on the second frame mechanism 8; the first frame mechanism 5 and the second frame mechanism 8 are left and right connected, the first driving mechanism 1 is arranged in the first frame mechanism 5, and the second driving mechanism 2 is arranged in the second frame mechanism 8; the first driving mechanism 1 can drive the first bed board 3 to overturn, and the second driving mechanism 2 can drive the second bed board 4 to overturn; the first frame mechanism 5 comprises a first movable frame 51 and a first fixed frame 52; the first movable frame 51 is movably connected to the first fixed frame 52 and can reciprocate along the bed length direction; the first bed board 3 and the second bed board 4 are flexible bed boards. In the embodiment, the first bed board 33 and the second bed board 44 are sequentially distributed from a bed head OA part to a bed tail OB part; the driving mechanism is used for driving the overturning of the bed board, the first frame mechanism 5 is divided into the first movable frame 51 and the first fixed frame 52, so that the electric bed can realize the function of leaning against the wall in the back area while overturning.

[0082] Further, as shown in the figure, Figure 2 、 Figure 3 the first fixed frame 52 comprises a first horizontal frame 521, a second horizontal frame 522, a first vertical frame 523 and a second vertical frame 524 and forms a rectangular frame; the first horizontal frame 521 and the second horizontal frame 522 are groove type frames; the groove type opening directions of the two horizontal frames are towards the inside of the bed body. The first movable frame 51 can reciprocate in the first fixed frame 52, and the movable frame of the traditional rigid electric bed is arranged on the upper side of the fixed frame. Compared with this, the improved movable frame and fixed frame are more compact and beautiful in volume.

[0083] Further, the first movable frame 51 comprises a third horizontal frame 511, a fourth horizontal frame 512, a third vertical frame 513 and a fourth vertical frame 514 and forms a rectangular frame; at least one pulley is arranged on the outer side of the third horizontal frame 511 and the fourth horizontal frame 512, the first movable frame 51 can slide in the groove type frame of the first horizontal frame 521 and the second horizontal frame 522, and the first movable frame 51 is slidably connected with the first fixed frame 52. The rectangular frame of the quadrilateral is matched with the groove type opening in the first fixed frame 52 through the pulley, and the function of reciprocating the first movable frame 51 in the first fixed frame 52 is realized.

[0084] Further, the first movable frame 51 can also include a third horizontal frame 511, a fourth horizontal frame 512, a third vertical frame 513 and form a concave frame with the opening facing the bed tail OB; at least one pulley is arranged on the outer side of the third horizontal frame 511 and the fourth horizontal frame 512, and the first movable frame 51 can slide in the groove-shaped frame of the first horizontal frame 521 and the second horizontal frame 522; the first movable frame 51 is slidingly connected with the first fixed frame 52. In this embodiment, the concave frame with three edges cooperates with the pulley, which not only can match the groove-shaped opening in the first fixed frame 52 to complete the reciprocating movement of the first movable frame 51 in the first fixed frame 52, but also reduces the weight of the first movable frame 51.

[0085] Further, the first driving mechanism 1 includes a first driving motor 11, a ninth vertical frame 12, and an upper body support structure 7; the upper body support structure 7 includes a back support structure 71 and a head support structure 72, which are respectively used to drive the first bed plate 3 to overturn and strengthen the support strength of the first bed plate 3; the head support structure 72 is hingedly connected with the back support structure 71, and the head support structure 72 is closer to the bed head OA direction; the ninth vertical frame 12 is arranged in the first fixed frame 52 between the first vertical frame 523 and the second vertical frame 524, preferably arranged parallel to the first vertical frame 523 and the second vertical frame 524 with the same distance; the both ends of the ninth vertical frame 12 are fixedly connected with the first horizontal frame 521 and the second horizontal frame 522; one end of the first driving motor 11 is connected with the ninth vertical frame 12, and the other end is connected with the back support structure 71. One end of the first driving motor 11 is directly arranged on the ninth vertical frame 12, so that the first driving motor 11 is located in the front half of the first bed plate 3, i.e. the back and head area, then the head support structure 72 is pushed to overturn, and the whole first bed plate 3 is overturned through the linkage members of the head support structure 72 and the back support structure 71; and the movable frame is driven to move towards the bed head OA through the pull rod, so as to realize the function of the back area leaning against the wall. In the traditional rigid bed plate electric bed, the motor needs to push the back support structure 71 and the head support structure 72 at the same time, or the back support structure 71 and the head support structure 72 need to be provided with two motors respectively to push them to overturn. This improvement can greatly reduce the power consumed by the motor and save the cost consumed on the motor.

[0086] Further, as Figure 9As shown, the quadrilateral frame 721 is hingedly connected with the back support structure 71 through a double L-shaped connecting piece 726. The double L-shaped connecting piece 726 is composed of two oppositely directed L-shaped connecting pieces, one face of each L-shaped connecting piece coincides with one face of the other L-shaped connecting piece and a bolt hole is formed, and the two are hingedly connected by a bolt; the other face is fixedly connected with the quadrilateral frame 721 and the back support structure 71, respectively. In this embodiment, a plurality of double L-shaped connecting pieces 726 are arranged on the quadrilateral frame 721 and the back support structure 71, which can effectively connect the quadrilateral frame 721 and the back support structure 71, and more effectively support the head support structure 72 when it is turned over.

[0087] Further, as shown in Figure 3 , Figure 8 the back support structure 71 is in the shape of a quadrilateral and includes a first back horizontal rod 711, a second back horizontal rod 712, a first back vertical rod 713, a second back vertical rod 714, a first hinged seat 715, a second hinged seat 716, a first push rod 717, and a second push rod 718. The first back horizontal rod 711, the second back horizontal rod 712, the first back vertical rod 713, and the second back vertical rod 714 are installed below the first bed plate 3 and form a quadrilateral frame 721, which is used to support the support strength of the bed plate in this area. The first hinged seat 715 and the second hinged seat 716 are installed below the first bed plate 3 along the bed length direction and are located within the quadrilateral frame 721. The first hinged seat 715 and the second hinged seat 716 are in the shape of a V-shaped frame, and the opening direction faces the opposite side of the first bed plate. One end of the first push rod 717 is connected with the third vertical frame 513, and the other end is hingedly connected with the first hinged seat 715. One end of the second push rod 718 is connected with the third vertical frame 513, and the other end is hingedly connected with the second hinged seat 716. In this embodiment, the two hinged seats are symmetrically arranged with the center line of the bed length direction as the axis. When the first drive motor 11 drives the head support mechanism to turn over, the pull rod makes a circular motion to drive the first push rod 717 and the second push rod 718 hinged on the hinged seat. The first push rod 717 and the second push rod 718 connected with the third vertical frame 513 drive the movable frame to move towards the bed head OA direction, realizing the wall-relying function of the back area of the first bed plate 3. And it continues to push the turning over of the back support structure 71 and the head support structure 72, reducing the power consumption of the first drive motor 11, and the arrangement on both sides also improves the stability of the turning over of the first bed plate 3.

[0088] Further, as shown in Figure 8As shown, the head support structure 72 includes a quadrilateral frame 721, a first headrest plate 722, a second headrest plate 723, a first limiting clamp 724, and a second limiting clamp 725. The quadrilateral frame 721 is fixedly installed on the back of the first bed plate 3 and is closer to the bed head OA direction relative to the back support structure 71. One end of the first limiting clamp 724 is hingedly connected to the first hinge seat 715, and the other end is hingedly connected to the first headrest plate 722. One end of the second limiting clamp 725 is hingedly connected to the second hinge seat 716, and the other end is hingedly connected to the second headrest plate 723. The first headrest plate 722 and the second headrest plate 723 are installed in the quadrilateral frame 721 along the bed length direction. The first limiting clamp 724 and the second limiting clamp 725 can control the turning angle of the head support structure 72 when the head support structure 72 and the back support structure 71 are linked to turn over. When the normal angle between the user's head and back is reached, the turning angle can be clamped to prevent the head support structure 72 from continuing to turn over, thereby improving the user's comfort during use.

[0089] Further, as shown in Figure 8 The first headrest plate 722 and the second headrest plate 723 are L-shaped and are installed below the first bed plate 3.

The L-shaped headrest plate can be fixedly connected to the back of the first bed plate 3 on one side and hingedly connected to the limiting clamp on the other side. The L-shaped headrest plate is a key component for linking the head support structure 72 and the back support structure 71, and is connected to the back support structure 71 on one side and used to strengthen the support strength of the head region of the first bed plate 3 on the other side.

[0090] Further, as shown in Figure 3 , as shown in Figure 5As shown, the first fixed frame 52 is provided with a first L-shaped frame 525 and a second L-shaped frame 526, a first pull rod 527 and a second pull rod 528; the first L-shaped frame 525 and the second L-shaped frame 526 are respectively installed at two top corners of the lower frame close to the bed head OA direction; the first pull rod 527 and the second pull rod 528 are installed along the length direction of the bed body, one end of the first pull rod 527 and the second pull rod 528 is hingedly connected with the first L-shaped frame 525 and the second L-shaped frame 526, and the other end is hingedly connected with the first hinged seat 715 and the second hinged seat 716. When the first bed plate 3 starts to overturn under the drive of the first drive motor 11, the first hinged seat 715 and the second hinged seat 716 connected to the back of the first bed plate 3 overturn upward, driving the first pull rod 527 and the second pull rod 528 to make circular motion toward the bed head OA, and driving the first push rod 717 and the second push rod 718 hingedly connected to the hinged seat; the first push rod 717 and the second push rod 718 connected to the third longitudinal frame 513 drive the movable frame to move toward the bed head OA, realizing the wall-relying function of the back area of the first bed plate 3. The two pull rods can also prevent the baby from entering the back space by mistake on both sides of the bed.

[0091] Further, as shown in Figure 2 、 Figure 4 , the second frame mechanism 8 includes a second movable frame 81 and a second fixed frame 82; the second movable frame 81 can reciprocate along the length direction of the bed based on the second fixed frame 82. The second frame is also provided with a fixed frame and a movable frame structure to cooperate with the movement of the first frame mechanism 5 toward the bed head OA.

[0092] Further, the second fixed frame 82 is provided with a fifth horizontal frame 821, a sixth horizontal frame 822, a fifth longitudinal frame 823 and a sixth longitudinal frame 824 to form a rectangular frame; the fifth horizontal frame 821 and the sixth horizontal frame 822 are groove-shaped frames; the groove-shaped opening direction of the two horizontal frames faces the bed body; the second movable frame 81 includes a seventh horizontal frame 811, an eighth horizontal frame 812, a seventh longitudinal frame 813 and an eighth longitudinal frame 814 to form a rectangular frame; the outer side of the seventh horizontal frame 811 and the eighth horizontal frame 812 is provided with at least one pulley; the pulley is embedded in the groove-shaped frame of the fifth horizontal frame 821 and the sixth horizontal frame 822, so that the second movable frame 81 is slidingly connected in the second fixed frame 82. The second movable frame 81 can reciprocate in the second fixed frame 82, while the movable frame of the traditional rigid electric bed is placed on the upper side of the fixed frame. Compared with this, the improved movable frame and fixed frame are more compact and beautiful in size.

The lower body support structure 9 is fixedly installed below the second bed plate 4 and close to the head OA direction of the bed, and the second driving mechanism 2 drives the lower body support structure 9 to overturn the second bed plate 4.

[0095] Further, the two sides of the lower body support structure 9 are hingedly connected with the second movable frame 81. When the lower body support structure 9 is overturned, it can move together with the second movable frame 81 to the head OA direction of the bed.

[0096] Further, as shown in FIG. 1, the second driving mechanism 2 comprises a second driving motor 21, a second transmission mechanism 22 and a lower body support structure 9.

In this embodiment, the entire lower body support structure 9 is a U-shaped frame, which not only satisfies the function of the second drive mechanism 2 driving the second bed board 4 to flip, but also strengthens the back support strength of the second bed board 4.

[0097] Furthermore, the first leg U-shaped frame 991 and the second leg U-shaped frame 992 are symmetrically arranged about the center line of the bed's length direction. This symmetrical arrangement ensures that the flexible bed board is subjected to uniform force when it is turned over, preventing uneven force on the flexible bed board and thus avoiding damage to it.

The two ends of the first support connecting rod 98 are hingedly connected with the frame, and the motor end is connected with the plastic clamp 22, so that the C surface of the first support connecting rod 98 is always under stress when the second bed board 4 is turned over, the possibility of stress deformation of the first support connecting rod 98 is reduced, and a metal piece with lighter material can be used to reduce the product cost.

[0100] Further, one end of the plastic clamp 22 is provided with a circular groove base for connecting the head of the second driving motor 21; the other side of the plastic clamp 22 is provided with a U-shaped groove for connecting the first support connecting rod 98.

[0101] Further, as shown in the drawings, Figure 1 Further, as shown in the drawings, one end of the first leg part support cross rod 94, the second leg part support cross rod 95, the third leg part support cross rod 96 and the fourth leg part support cross rod 97 towards the bed tail OB is in a circular arc shape, and the circular arc opening is downward. The circular arc is arranged to make the leg part bed board part bending part a circular arc transition when the bed board is turned over, better fit the angle of the user's thigh and calf, and improve the comfort of the user.

[0102] Further, the second driving mechanism 2 is provided with a calf turning rod 23; the calf turning rod 23 includes a first part 231, a second part 232 and a third part 233; the first part 231, the second part 232 and the third part 233 form a U-shaped structure; the first part 231 and the third part 233 are hingedly connected with the seventh cross frame 811 and the eighth cross frame 812 respectively; the second part 232 is fixedly connected below the second bed board 4. As shown in the drawings, Figure 3As shown, the calf turning lever 23 is installed on the second deck board 4 near the bed tail OB; when the second driving mechanism 2 drives the second deck board 4 to turn, the second deck board 4 is lifted, and at this time, the calf plate is hingedly connected with the second movable frame 81, so that the tail of the second deck board 4 can be pulled down to turn, and the leg movement of the user is better matched.

[0103] Further, as shown in the drawings, Figure 10 Further, as shown in the drawings,

[0104] Further, the flat frame is provided with a plurality of groups of bolt holes, each group having at least one bolt hole; the concave frame is provided with a plurality of groups of waist-shaped holes corresponding to each group of bolt holes; when the flat frame is embedded in the concave frame, the area of each group of waist-shaped holes can surround the area of each group of bolt holes. By opening the waist-shaped hole and tightening the bolt in the waist-shaped hole, the height of the nut after the bolt is tightened does not exceed the height of the waist-shaped hole, so that the whole electric bed is more beautiful.

[0105] Further, the first movable frame 51 is fixedly connected with the second movable frame 81. After the first movable frame 51 is fixedly connected with the second movable frame 81, when the first movable frame 51 moves towards the bed head OA, the second movable frame 81 can be driven to move towards the bed head OA together, and the synchronization performance is better.

[0106] Further, as shown in the drawings, Figure 3 , Figure 4As shown, the first movable frame 51 is internally provided with a first hip plate 61; three edges of the first hip plate 61 are fixedly connected with the third horizontal frame 511, the fourth horizontal frame 512 and the third vertical frame 513 respectively; the second movable frame 81 is internally provided with a second hip plate 62; three edges of the second hip plate 62 are fixedly connected with the seventh horizontal frame 811, the eighth horizontal frame 812 and the seventh vertical frame 813 respectively. In the abutting area of the first movable frame 51 and the second movable frame 81, the first hip plate 61 and the second hip plate 62 are arranged, so that the support strength of the flexible bed board in the area can be better enhanced; the upper surfaces of the first hip plate 61 and the second hip plate 62 are flush with the upper surfaces of the first movable frame 51 and the second movable frame 81; the flexible bed board can be made more flush. The first hip plate 61 and the second hip plate 62 can be made of wooden boards, so that the whole bed structure can be lighter in weight than the conventional support plate.
