Description

Technical Field

[0001] This utility model relates to the technical field of electric bed frame devices, and in particular to an electric bed frame with a bed surface rotation function. Background Technology

[0002] With social development, technological advancements, and improved living standards, people's demand for a high-quality life is increasing. Electric beds, once only found in the medical field, are now entering people's daily lives. Compared to conventional flat beds, electric beds allow for both backrest and leg-raising. Backrest raising makes reading, watching TV, and browsing videos in bed more convenient; leg-raising promotes blood circulation, reduces fatigue, and helps prevent illness.

[0003] Currently, electric beds are generally expensive, with a wide variety of functions and varying quality. Commonly used two-function electric beds, including backrest and legrest lifts, boast unique designs and excellent functionality, making them suitable for young people.

[0004] When designed for elderly users, although raising the back or legs will cause the bed to form a chair shape, allowing the elderly to sit, they usually get out of bed from the side. However, it is still difficult for the elderly facing the other end of the bed to get out. To make it easier for the elderly to get out of bed, an electric bed frame with a rotating bed surface has been designed, which allows the elderly in a sitting position to rotate to the side of the bed, making it easier for them to get out of bed.

[0064] The device can shape the bed surface into a seat and rotate it 90 degrees, making it easier for the elderly to get out of bed;

[0065] The lower leg plate remains stationary while forming the seat-like bed surface assembly. It moves backward as the seat-like bed surface assembly rotates, preventing it from obstructing the assembly. This solves the problem of insufficient mattress thickness in rotating beds. Furthermore, the backward movement of the lower leg plate ensures that the deformed mattress has enough space to fully cover the seat-like bed surface assembly. This represents a significant improvement over traditional mattresses where the mattress cannot fully cover the bed surface assembly when the legs or back are raised. Even when the elderly person remains in bed, the mattress can still effectively serve them, fully covering the bed surface assembly without any obstruction, providing a better experience. This technology represents a significant advancement over traditional electric beds. Attached Figure Description

[0086] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0087] This utility model relates to an electric bed frame with a rotating bed surface, equipped with four motors: one backrest motor, one thigh motor, one lower leg motor, and one rotation motor. The main functions of the bed are: backrest lifting, thigh lifting, upper lower leg lifting, bed surface rotation, and lower lower leg push-back function. Its advantage lies in solving the problem of difficulty for elderly people getting out of bed, allowing them to perform caregiving in bed, as well as watch movies and relax in bed. The lower lower leg push-back function also solves the problem of traditional rotating beds not being able to use very thick mattresses, as the bed surface will not interfere with the mattress on the lower lower leg board during rotation.

[0088] The overall structure of the rotating bed is as follows Figure 2 As shown: The bed frame assembly 3 consists of a left side frame tube 311, a backrest support tube 312, a single V-shaped roller groove 313, a right side frame tube 314, head and tail horizontal tubes 321, a backrest fixing upright tube 322, a frame corner piece 323, a rotating frame horizontal tube 331, a fixed rotating disc lower section 332, a middle pull tube 341, a large turntable 342, a rotating motor frame horizontal tube 351, a lower leg wooden board support tube 352, a stabilizing frame fixing tube 353, a rotating motor insert 354, and a motor fixing piece 355. The backrest support tube 312 and the single V-shaped roller groove 313 are welded to the left side frame tube 311 and the right side frame tube 314, respectively. The backrest fixing upright tube 322 is welded to the head and tail horizontal tubes 321 and fixed to the left side frame tube 311 and the right side frame tube 314 via the frame corner piece 323. The fixed rotating disk 332 is welded to the horizontal tubes 331 of the rotating frame on both sides, and the stabilizing frame fixing tube 353 is welded to the horizontal tube 351 of the motor frame and fixed between the left side tube 311 and the right side tube 314 of the frame. The intermediate pull tube 341 is fixed between the horizontal tube 331 of the rotating frame and the horizontal tube 351 of the motor frame, serving a supporting function. The lower leg wooden board support tube 352 is fixed to the horizontal tube 351 of the motor frame, serving to support the upper lower leg board 15. The large turntable 342 is installed on the horizontal tube 331 of the rotating frame and fixed by the intermediate pull tube 341.

[0089] The outer walls of the left side frame tube 311, the right side frame tube 314, and the two front and rear horizontal tubes 321 of the frame are equipped with frame components 2.

[0090] Bed leg assemblies 8 are installed at the bottom of each of the four frame corner pieces 323.

[0091] The turntable frame assembly 5 consists of a left turntable frame tube 511, a roller fixing pin 512, a turntable frame roller 513, a lifting frame rotating shaft sleeve 514, a right turntable frame tube 515, angle iron lugs 516, a fixed rotating disc upper 521, a middle horizontal tube upper 522, a middle horizontal tube lower 531, a leg motor connecting piece 532, a back motor connecting piece 533, and a turntable frame pull tube 534. The turntable frame pull tube 534 is welded between the two middle horizontal tubes lower 531. The leg motor connecting piece 532 and the back motor connecting piece 533 are welded to the middle horizontal tubes lower 531. The fixed rotating disc upper 521 is fixed to the two middle horizontal tubes upper 522; its left and right rotation allows for left-hand and right-hand rotation switching. The reverse direction shown in the diagram is right-hand rotation. The middle horizontal tube upper 522 and the middle horizontal tube lower 531 are installed between the left turntable frame tube 511 and the right turntable frame tube 515. The turntable frame roller 513 is mounted on the left side 511 of the turntable frame tube via roller fixing pin 512, and can rotate freely. The turntable frame assembly 5 is fixed to the butt plate 13 via angle iron lugs 516.

[0092] The back lifting frame 4 consists of a back lifting tube 411, a back motor fixing component 412, a back lifting side plate 413, a V-shaped roller mounting plate 414, and V-shaped small rollers 415. The leg lifting frame 6 consists of a leg lifting tube 611, a thigh motor fixing component 612, a first calf motor fixing component 613, a leg lifting side plate 614, and leg lifting frame rollers 615. The back lifting tube 411 of the back lifting frame 4 is installed in the lifting frame rotating shaft sleeve 514 on the turntable frame assembly 5, and the same applies to the leg lifting frame 6, allowing free rotation. The tail of the back lifting motor 416 is installed on the back motor connecting piece 533 on the turntable frame assembly 5, and the head is installed on the back motor fixing component 412. The tail of the thigh lifting motor 616 is installed on the calf motor connecting piece 532 on the turntable frame assembly 5, and the head is installed on the thigh motor fixing component 612. The calf board reinforcing tube 622 is installed on the upper calf plate 15, and the second calf motor fixing part 621 is welded to the calf board reinforcing tube 622. The tail of the calf lifting motor 623 is installed on the second calf motor fixing part 621, and the head is installed on the first calf motor fixing part 613. The back leg lifting process is as follows: when the back lifting motor 416 is pushed, the back lifting round tube 411 rotates in the lifting frame rotating shaft sleeve 514, causing the back lifting side plate 413 to swing. The V-shaped small rollers 415 on the V-shaped roller mounting plate 414 slide in the V-shaped groove, thereby lifting the back plate 11. When the thigh lifting motor 616 is pushed, the leg lifting round tube 611 rotates in the lifting frame rotating shaft sleeve 514, causing the leg lifting side plate 614 to swing, thereby lifting the thigh plate 14. The calf lifting motor 623 is installed between the first calf motor fixing part 613 and the second calf motor fixing part 621, and the upper calf plate 15 will also be lifted due to the support of the calf lifting motor 623. The pushing and retracting of the calf lifting motor 623 will also adjust the angle between the calf plate 15 and the thigh plate 14.

[0093] The bed surface rotation function mainly consists of a fixed rotating disk lower 332, a fixed rotating disk upper 521, a power disk rotating arm 911, a power disk 912, a power disk support 913, a ball bearing retainer 914, and a rotary motor 915. The power disk rotating arm 911 is welded to the power disk 912. The rotating disk frame assembly 5 is fixed to the hip plate 13. A ball bearing retainer 914 is installed between the bed surface frame assembly 3 and the rotating disk frame assembly 5, located between the fixed rotating disk lower 332 and the fixed rotating disk upper 521, allowing the rotating disk frame assembly 5 to rotate freely 360°. A ball bearing retainer 914 is also installed between the fixed rotating disk lower 332 and the power disk 912, allowing the power disk 912 and the fixed rotating disk lower 332 to rotate freely 360°. The power disk support 913 is placed between the power disk 912 and the fixed rotating disk upper 521, restricting the relative position of the power disk 912. Then, a long screw is passed through the round hole of the power plate 912 and fixed to the fixed rotating plate 521. Because the power plate 912 and the fixed rotating plate 521 are fixed with screws, the fixed rotating plate 521 will rotate as the power plate 912 rotates. The power plate support 913 is placed within it, allowing the two ball bearing retainers 914 to rotate freely. The tail of the rotary motor 915 is mounted on the rotary motor fixing component 355, which in turn is mounted on the rotary motor frame cross tube 351 and fixed with screws. The rotary motor insert 354 is installed below the rotary motor fixing component 355 to adjust the installation stroke of the rotary motor 915, preventing the bed surface from failing to return to the zero position due to errors. The head of the rotary motor 915 is mounted on the power plate rotating arm 911. The bed surface rotation process is as follows: when the rotary motor 915 push rod retracts, the power plate rotating arm 911 drives the power plate 912 to rotate. Because the relative positions of the power plate 912 and the fixed rotating plate 521 are fixed, the turntable frame assembly 5 rotates with the power plate 912, and the bed surface assembly 1 also rotates. The bed surface frame assembly 3, because it is equipped with two ball bearing retainers 914, does not rotate with the bed surface. During rotation, the turntable frame rollers 513 roll on the large turntable 342, enhancing stability during rotation.

[0094] The rear-push functional component 7 mainly consists of a lower leg plate 16, a single V-shaped roller groove 313, an upper intermediate horizontal tube 522, a front pivot point 711 for the connecting rod, a shaped connecting rod 712, a rear pivot point 713 for the connecting rod, a stable frame round tube 721, a stable frame swing arm 722, a stable frame connecting piece 723, a movable frame connecting piece 731, a movable frame horizontal tube 732, a right movable frame side tube 733, and a left movable frame side tube 734. The shaped connecting rod 712 is installed on the upper intermediate horizontal tube 522 via the front pivot point 711 and on the movable frame horizontal tube 732 via the rear pivot point 713. The stable frame swing arm 722 is welded to the stable frame round tube 721, and the stable frame round tube 721 is installed on the stable frame fixed tube 353 and can rotate freely. The movable frame connecting piece 731 is welded to the movable frame horizontal tube 732. The movable frame horizontal tube 732 is installed between the right side tube 733 and the left side tube 734 of the movable frame. Movable frame rollers 735 and movable frame limiting plastic parts 736 are installed on the right side tube 733 and the left side tube 734. The upper part of the right side tube 733 and the left side tube 734 is fixed to the lower leg plate 16, and the sides are installed on the single V-shaped roller groove 313 via the movable frame rollers 735, allowing for free forward and backward sliding. The movable frame connecting piece 731 is connected to the stabilizer arm 722 via the stabilizer connecting piece 723. The push-back function is as follows: the rotary motor 522 retracts, the turntable assembly 5 begins to rotate, pushing the irregular connecting rod 712 on the fixed middle horizontal tube 522. The irregular connecting rod 712 pushes the rear pivot point 713 of the connecting rod, causing the movable frame horizontal tube 732 to move backward. The movable frame rollers 735 are installed in the single V-shaped roller grooves 313 on both sides. During the backward movement of the movable frame horizontal tube 732, it moves in a straight line, simultaneously causing the lower leg plate 16 to move back and forth. To address the issue of uneven force distribution on the movable frame horizontal tube 732 due to unilateral force, the movable frame connecting piece 731 on the other side is connected to the stabilizer arm 722 via the stabilizer connecting piece 723. This ensures that even under unilateral force, the movable frame horizontal tube 732 remains perpendicular to the left side tube 311 of the frame via the stabilizer connecting piece 723.

[0095] This electric bed with a rotating surface is primarily designed for the elderly, assisting them with getting out of bed and daily care. Unlike other rotating electric beds on the market, it features a lower leg rest that pushes back, ensuring no interference between the front and rear of the bed at any angle, thus solving the problem of excessively thick mattresses in rotating beds. The entire bed also adopts a detachable structure, reducing dimensional errors caused by welding. Several inserts are installed at the rotating motor's mounting points, allowing adjustment of the motor's dimensions by adding or removing these inserts, preventing the bed surface from failing to return to the zero position due to errors.

[0096] The specific implementation is as follows: First, the long screws fix the power plate 912 and the fixed rotating plate 521. Then, the thigh lifting motor 616, the calf lifting motor 623, and the back lifting motor 416 are started, so that the back plate 11, waist plate 12, buttock plate 13, thigh plate 14, and upper calf plate 15 form a seat position.

[0097] The start of the rotary motor 915 causes the power plate arm 911, the power plate 912, and the fixed rotary plate 521 to rotate, thereby causing the back board 11, waist board 12, hip board 13, thigh board 14, and upper leg board 15 to form a seat rotation, allowing the elderly to rotate 90 degrees in a seated position. When the fixed rotary plate 521 rotates, it drives the lower leg board 16 to push backward, so that the bed foam pad is not obstructed by the lower leg board 16, and the foam pad can always maintain a good condition to cover the bed surface. The 90-degree rotation of the bed surface makes it easier for the elderly to get out of bed from the side.

[0098] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
