[0023] The present application provides a multifunctional nursing bed for convenient deformation of a bed body state, which solves the technical problem of high control difficulty and easy failure in the prior art due to mutual linkage of multiple push rods. The deformation function is realized by a push rod pushing a connecting rod connected with a lower leg plate and a foot plate, respectively. When the push rod is retracted to zero position, the mechanism is in a sitting-up state. When the push rod is extended to the end of stroke, the mechanism is deformed into a flat bed state. The multifunctional nursing bed can realize multi-angle deformation with fewer components, reduces the number of push rods compared with the traditional structure relying on multiple push rods, reduces complexity and failure rate, and improves the technical effect of operation convenience.
[0024] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the present application is not limited to the example embodiments described herein. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application. In addition, it should be noted that only parts related to the present application are shown in the drawings for convenience of description.
[0025] Please refer to the accompanying drawings Figure 1 , the accompanying drawings Figure 2 , the accompanying drawings Figure 3 , the accompanying drawings Figure 4 , the present application provides a multifunctional nursing bed for convenient deformation of a bed body state, comprising:
[0026] The bed body structure is directly contacted with objects; the head of the starting linkage structure 5 is connected with the bed body structure through a hinge pin; the head of the push rod 4 is connected with the tail of the starting linkage structure 5 through a hinge pin; wherein the side close to the bed body structure is defined as the head, and the end far from the bed body structure is defined as the tail; the extension and retraction movement of the push rod 4 is transmitted through the starting linkage structure 5 and acts on the bed body structure to perform the deformation control of the bed body structure.
[0027] Specifically, the bed body structure is the main part of the entire nursing bed, which is directly contacted with external objects and used to support the body of a user. The starting linkage structure 5 is located beside the bed body structure, and the head thereof is connected with the bed body structure through a hinge pin to ensure the flexible movement between the linkage and the bed body. The push rod 4 is installed at the tail of the starting linkage structure 5 and is also connected through a hinge pin, and the movement of the push rod 4 is controlled by extension and retraction. The part close to the bed body is defined as the head of the push rod 4, and the part far from the bed body is defined as the tail of the push rod 4. When the push rod 4 performs the extension and retraction movement, the force thereof is transmitted to the bed body structure through the starting linkage structure 5 to push the deformation of the bed body. The extension and retraction movement of the push rod 4 generates force to the linkage, which in turn acts on the bed body structure to realize the deformation control of the nursing bed from the lying state to the sitting state.
[0028] Preferably, the tail of the push rod 4 is fixedly connected with the fixed frame through a hinge pin, and the tail of the starting linkage structure 5 is fixedly connected with the fixed frame through a hinge pin.
[0029] Specifically, the tail of the push rod 4 is connected with the second mounting seat 7 through a hinge pin to be fixedly connected with the fixed frame, so as to keep the tail of the push rod 4 stable on the fixed frame and provide support for the extension and retraction movement of the push rod 4. Meanwhile, the tail of the starting linkage structure 5 is also connected with the first mounting seat 6 through a hinge pin to be fixedly connected with the fixed frame. This connection mode enables one end of the starting linkage structure 5 to be stably attached to the fixed frame, and the other end to be flexibly transmitted through the connection with the push rod 4. When the push rod 4 performs the extension and retraction movement, the force is transmitted to the bed body structure through the starting linkage structure 5 to push the corresponding deformation of the nursing bed, and the fixed frame plays a key role in stabilizing the structure and supporting the transmission process. Preferably, the fixed frame is a mounting seat.
[0030] Preferably, the bed body structure comprises: a hip plate 1 installed on the fixed frame; a calf plate 2 having a first end connected with the hip plate 1 through a hinge, and the number of the hinges is multiple; and a foot plate 3 connected with a second end of the calf plate 2 through a hinge.
[0031] Specifically, the bed structure includes multiple key components to ensure that the bed can deform flexibly and meet the needs of the user. First, the hip plate 1 serves as the base part of the bed, which is firmly installed on the fixed frame to provide support for the entire bed structure. One end of the calf plate 2 is connected to the hip plate 1 through multiple hinges, which allow the calf plate 2 to rotate and adjust at different angles to achieve flexible deformation of the bed. The other end of the calf plate 2 is connected to the foot plate 3 through hinges, which also provide flexible rotation function, so that the foot plate 3 and the calf plate 2 can work together. Through this hinge connection design, the lower body part of the nursing bed (calf plate 2 and foot plate 3) can achieve smooth angle adjustment to adapt to different sitting or lying needs, providing a more comfortable nursing experience for the user.
[0032] Preferably, the starting linkage structure 5 is composed of multiple links through hinge pins.
[0033] Specifically, in the preferred design, the starting linkage structure 5 is composed of multiple links through hinge pins. These links are flexibly connected through hinge pins to form an integrated starting linkage structure 5 system. The use of hinge pins ensures smooth movement between the links, allowing the entire linkage structure to move freely in different directions and angles. When the push rod 4 performs an extension and retraction movement, the force is transmitted through these interconnected links in sequence, ultimately acting on the bed structure to push the bed to achieve the required deformation. Through the combination of multiple links, the starting linkage structure 5 can ensure stability while achieving flexible power transmission, effectively improving the accuracy and reliability of the deformation control of the nursing bed.
[0034] Preferably, the starting linkage structure 5 is a bifurcated tree structure, the first leaf node end, the second leaf node end and the third leaf node end are the head, the first leaf node end and the second leaf node end are connected to the calf plate 2 through hinge pins, the third leaf node end is connected to the foot plate 3 through a hinge pin, and the fourth leaf node end is the tail, which is installed with a hinge pin connected to the fixed frame.
[0035] Specifically, the starting linkage structure 5 adopts a bifurcated tree structure design to achieve multi-point deformation control of the nursing bed. The first leaf node end, the second leaf node end and the third leaf node end of the starting linkage structure 5 serve as the head, which are connected to the calf plate 2 and the foot plate 3 through hinge pins respectively. Among them, the first leaf node end and the second leaf node end are fixed on different positions of the calf plate 2 through hinge pins, ensuring that the calf plate 2 can deform accurately when subjected to the force transmitted by the push rod 4, while the third leaf node end is connected to the foot plate 3 through a hinge pin, so that the foot plate 3 can also adjust the angle and work together with the calf plate 2.
[0036] The fourth leaf node end of the starting linkage structure 5 is designed as a tail, which is stably connected to the fixed frame through a hinge pin. The bifurcated tree structure ensures that the starting linkage structure 5 can exert force on different nodes simultaneously, so that the calf plate 2 and the foot plate 3 deform in coordination under the control of the push rod 4, realizing a smooth transition of the bed body from lying to sitting. This structure not only improves the stability of control, but also increases the deformation accuracy of the nursing bed, meeting the diverse needs of users.
[0037] Preferably, as shown in the accompanying drawings Figure 1 and the accompanying drawings Figure 2 By controlling the rearward retraction of the push rod 4, the starting linkage structure 5 drives the calf plate 2 and the foot plate 3 to deform the bed body structure into a first critical state, which is a sitting state.
[0038] Specifically, by controlling the rearward retraction of the push rod 4, the starting linkage structure 5 starts to move and transfers force to the calf plate 2 and the foot plate 3. During the rearward retraction of the push rod 4, the starting linkage structure 5 gradually lifts the calf plate 2 and the foot plate 3 at a preset angle, eventually deforming the bed body structure and transitioning from a lying state to a first critical state, i.e., a sitting state. In this state, the calf plate 2 is lifted, the foot plate 3 is lifted synchronously, and the lower part of the nursing bed assumes a posture suitable for the user to sit up. This sitting state provides comfortable support for the user, facilitating their daily activities or nursing operations. By accurately controlling the retraction amplitude of the push rod 4, the bed body deformation process can proceed smoothly, ensuring that the nursing bed achieves the desired sitting effect.
[0039] Preferably, as shown in the accompanying drawings Figure 3 and the accompanying drawings Figure 4 By controlling the forward extension of the push rod 4, the starting linkage structure 5 drives the calf plate 2 and the foot plate 3 to deform the bed body structure into a second critical state, which is a flat bed state.
[0040] Specifically, by controlling the forward extension of the push rod 4, the starting linkage structure 5 starts to work, and force is gradually transferred to the calf plate 2 and the foot plate 3. During the forward extension of the push rod 4, the starting linkage structure 5 gradually lowers the calf plate 2 and the foot plate 3, allowing the bed body structure to recover from the sitting state to the lying state, i.e., the second critical state. During this process, the calf plate 2 slowly descends to a position level with the hip plate 1, and the foot plate 3 also lowers to a horizontal state. Finally, the entire bed body returns to a flat bed state, suitable for patients or users to rest or sleep. This process is achieved by accurately controlling the forward extension movement of the push rod 4, ensuring that the deformation process of the nursing bed is smooth and comfortable, providing a smooth transition from sitting to lying.
[0041] Preferably, the bed state self-adaptive regulation is performed within the range of the first critical state and the second critical state by adjusting the forward extension amplitude and the backward retraction amplitude of the push rod 4.
[0042] Specifically, by precisely adjusting the forward extension and backward retraction amplitude of the push rod 4, the self-adaptive regulation can be performed between the first critical state (sitting-up state) and the second critical state (flat bed state) of the nursing bed. The movement amplitude of the push rod 4 determines the specific angle and deformation state of the bed structure, for example, slight forward extension of the push rod 4 will gradually transition the bed structure from the fully sitting-up state to the lying state, and vice versa, moderate backward retraction of the push rod 4 will gradually raise the bed from the flat bed state to the sitting-up state. Through this regulation mechanism, the nursing bed can realize flexible adjustment of multiple intermediate states to meet the comfort needs of users in different situations. This self-adaptive regulation mechanism can provide any angle change from fully lying to fully sitting-up according to the fine adjustment amplitude of the push rod 4, making the operation of the nursing bed more intelligent and personalized.
[0043] In summary, the multifunctional nursing bed for convenient deformation of bed state provided by the present application has the following technical effects:
[0044] The deformation function is realized by a push rod pushing the connecting rods connected with the calf plate and the foot plate respectively. When the push rod is retracted to the zero point, the mechanism presents a sitting-up state, and when the push rod is extended to the end of the stroke, the mechanism is deformed into a flat bed state. With fewer components, the multifunctional nursing bed can realize multi-angle deformation, compared with the traditional structure relying on multiple push rods, the number of push rods is reduced, the complexity and failure rate are reduced, and the technical effect of improving the convenience of operation is achieved.
