[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0034] See also Figure 1-Figure 11 As shown, the present invention is a dynamic support nursing bed for bedridden patients, comprising a bed frame 1, a fixed bed board 2 is fixed inside the bed frame 1, a first movable bed board 3 and a second movable bed board 4 are movably arranged on both sides of the fixed bed board 2, two support rods 5 are relatively fixed on the first movable bed board 3, the support rod 5 is rotatably connected to the bed frame 1, a rotating rod 6 is rotatably arranged on one side of the bed frame 1 away from the support rod 5, the second movable bed board 4 is arranged on the rotating rod 6, a transmission belt 7 is arranged between the support rod 5 and the rotating rod 6, a connecting rod 8 is fixed between the two support rods 5, a second gear 11 is arranged on the connecting rod 8, and a first gear 12 is meshed on the lower side of the second gear 11;

[0035] A connecting block 13 is fixed to a side of the second movable bed board 4 away from the fixed bed board 2 , a bed tail portion 14 is fixed to the connecting block 13 , and an anti-slip pad 15 is arranged on one side of the bed tail portion 14 .

[0036] In the above structure, through the meshing action of the first gear 12 and the second gear 11, combined with the rotational coordination of the support rod 5 and the bed frame 1, under the action of the connecting rod 8, it is convenient to adjust the two support rods 5 to rotate synchronously, thereby driving the first movable bed board 3 to flip relative to the fixed bed board 2, so as to support the back of the bedridden patient. At the same time, under the action of the transmission belt 7, combined with the rotational connection of the rotating rod 6 and the bed frame 1, the second movable bed board 4 is driven to flip synchronously, effectively supporting the legs of the bedridden patient. In the process of flipping the second movable bed board 4, the bed tail 14 is driven to flip, which is convenient for supporting the feet of the bedridden patient and facilitating the patient to get up without the assistance of a nursing staff. This solves the problem that most traditional nursing beds are generally fixed structures and can usually only provide static support, which is convenient for patients to lie down and rest. When patients try to get up, they need to rely on their own greater strength or the assistance of nursing staff, which increases the difficulty of patients getting up and easily leads to the risk of accidental injury. At the same time, it increases the workload of nursing staff, is not convenient for flexible adjustment according to the patient's getting up movements, and has poor use effect.

[0037] The end of the support rod 5 away from the connecting rod 8 passes through the bed frame 1, and the outer end of the support rod 5 is fixedly connected to a fixing block 9, and a first guardrail 10 is fixed on the fixing block 9. The first guardrail 10 facilitates the protection effect during the use of the nursing bed. Two limiting slots 22 are relatively opened on the top of the bed frame 1, and blocks 23 are fixed on the side where the two fixing blocks 9 are close to each other. The blocks 23 cooperate with the limiting slots 22. Limiting blocks 24 are fixed on the front and rear sides of the bed frame 1, and the limiting blocks 24 cooperate with the fixing blocks 9. Through the mutual cooperation between the limiting slots 22 and the blocks 23, combined with the mutual cooperation between the limiting blocks 24 and the fixing blocks 9, the fixing blocks 9 are effectively limited and supported, thereby ensuring the stability of the first guardrail 10.

[0038] A first Oxford cloth 16 is fixed between one end of the first movable bed board 3 and the fixed bed board 2, and a second Oxford cloth 17 is fixed between one end of the fixed bed board 2 away from the first Oxford cloth 16 and the end of the second movable bed board 4. The first Oxford cloth 16 is used to effectively block the gap between the first movable bed board 3 and the fixed bed board 2, and the second Oxford cloth 17 is used to block the gap between the second movable bed board 4 and the fixed bed board 2, thereby achieving the isolation and protection of the transmission belt 7, which facilitates the dynamic support use of the nursing bed.

[0039] A first notch 18 is provided on one side of the bottom of the first movable bed board 3, and the connecting rod 8 and the second gear 11 are both arranged on the inner side of the first notch 18. A second notch 19 is provided on one side of the bottom of the second movable bed board 4, and a groove 20 is provided on the bottom of the fixed bed board 2. The transmission belt 7 cooperates with the first notch 18, the groove 20 and the second notch 19. Two avoidance grooves 21 are relatively provided on the side of the first movable bed board 3 close to the fixed bed board 2, and the avoidance grooves 21 cooperate with the transmission belt 7. The avoidance grooves 21 facilitate the flipping of the first movable bed board 3, thereby effectively avoiding friction and collision with the transmission belt 7 during the flipping of the first movable bed board 3.

[0040] A support block 25 is fixed to one side of the inside of the bed frame 1, and the support block 25 cooperates with the bottom of the first movable bed board 3. A fixing bar 26 is fixed to the movable end of the first movable bed board 3, and the fixing bar 26 cooperates with the top of the bed frame 1. The support block 25 facilitates supporting the bottom of the first movable bed board 3, and the fixing bar 26 effectively limits the first movable bed board 3, thereby ensuring the stability of the first movable bed board 3 when it is in a horizontal state.

[0041] Two support plates 28 are relatively fixed at the bottom of the support block 25, and a rotating shaft 27 is rotatably arranged between the two support plates 28. The first gear 12 is arranged on the rotating shaft 27. A servo motor 29 is installed on the rear side of the bottom of the bed frame 1 through a bracket. The output end of the servo motor 29 is connected to the rear end of the rotating shaft 27. A control switch is installed on the first guardrail 10 on the rear side, and the control switch is electrically connected to the servo motor 29.

[0042] A headboard 30 is fixed to one side of the top of the bed frame 1, and two second guardrails 31 are relatively fixed to one side of the top of the bed frame 1 away from the headboard 30. The second guardrails 31 further improve the protective effect of the nursing bed during use, and at the same time provide the patient with a grippable handle when assisting the patient to get up, making it convenient for the patient to get up.

[0043] Example:

[0044] like Figure 1-Figure 8 As shown, in the initial state, the fixing bar 26 abuts against the top of the bed frame 1, the support block 25 abuts against the bottom of the first movable bed board 3, the first movable bed board 3 and the second movable bed board 4 are both in a horizontal state and in the same horizontal plane as the fixed bed board 2, so as to facilitate the patient to lie down with support;

[0045] When the patient needs to get up, the patient or the nursing staff can start the servo motor 29 through the control switch on the first guardrail 10 at the rear side, and the servo motor 29 drives the rotating shaft 27 to rotate, which drives the first gear 12 to rotate. Under the meshing action of the first gear 12 and the second gear 11, combined with the rotation cooperation of the support rod 5 and the bed frame 1, under the action of the connecting rod 8, the two support rods 5 are driven to rotate synchronously, and then the first movable bed board 3 is driven to flip relative to the fixed bed board 2, so as to effectively support the back of the bedridden patient;

[0046] During the rotation of the support rod 5, under the action of the transmission belt 7, combined with the rotation connection between the rotating rod 6 and the bed frame 1, the second movable bed board 4 is driven to turn over synchronously, effectively supporting the legs of the bedridden patient;

[0047] During the flipping of the second movable bed board 4, the bed foot 14 is also flipped to facilitate supporting the feet of the bedridden patient. The anti-slip pad 15 increases the friction of the patient's feet to prevent the patient from slipping when getting up.

[0048] like Figure 9-11 As shown, with the driving of the servo motor 29, until the first movable bed board 3 flips to a suitable angle, the second movable bed board 4 is driven to flip to a suitable angle synchronously, so that the first movable bed board 3, the fixed bed board 2 and the second movable bed board 4 form a seat structure, which, combined with the bed tail 14, acts as a foot pedal, thereby realizing dynamic support of the nursing bed, making it convenient for the patient to get up without the assistance of a nursing staff, and solving the problem that most traditional nursing beds are integral fixed structures and can usually only provide static support, making it convenient for the patient to lie down and rest. When the patient tries to get up, he needs to rely on his own greater strength or the assistance of a nursing staff, which increases the difficulty of the patient getting up and easily leads to the risk of accidental injury. At the same time, it increases the workload of the nursing staff, and is not convenient for flexible adjustment according to the patient's getting up action, resulting in poor use effect;

[0049] During the flipping process of the first movable bed board 3, the first guardrail 10 is also driven to flip synchronously. With the cooperation of the first guardrail 10 and the second guardrail 31, a support structure for the patient to hold when getting up is provided, which greatly reduces the difficulty of the patient getting up.

[0050] It should be further explained that the installation structure, connection method or setting method of each component in the present invention are all common mechanical methods, and they can be implemented as long as they can achieve their beneficial effects. At the same time, the servo motor 29 in the present invention is purchased on the market, and technical personnel in this field can install and use it as required.
