[0002] Electric load-bearing hospital beds, as an indispensable auxiliary device in modern medical systems, are widely used in general departments of hospitals and nursing homes. Their initial design purpose was to meet the practical needs of medical staff in their daily medical work, improve work efficiency, and provide patients with more precise and personalized nursing services, such as facilitating the calculation of weight and medication dosage.
[0003] In the structure of an electric load-bearing hospital bed, the upper bed frame leg panel assembly is one of the key components. It is mainly responsible for supporting the patient's legs and can adjust the tilt angle within a specified range according to medical needs, such as enabling the lower legs to bend inward or outward, in order to meet the requirements of different treatment and nursing scenarios.
[0004] However, the traditional way of implementing the leg support function of hospital beds has obvious drawbacks. The traditional design relies on an independent motor to directly drive the movement of the leg support, which requires an additional motor to be installed under the bed, resulting in a significant increase in production costs.

[0011] In one embodiment, the limiting groove includes a limiting section and a free section, the limiting section being connected to the free section; the limiting section is located on the side of the free section facing away from the bed frame; the length of the free section extending along the length direction of the bed frame is greater than the length of the limiting section extending along the length direction of the bed frame.
[0012] In one embodiment, the linkage component further includes a sliding wheel, which is rotatably connected to the lower leg plate and slidably connected to the bed frame.
[0013] In one embodiment, the pulley is rotatably connected to the end of the calf plate away from the thigh plate.
[0014] In one embodiment, the support assembly further includes a hip plate disposed on the bed frame and rotatably connected to the end of the thigh plate away from the calf plate.
[0015] In one embodiment, the support assembly further includes a back panel movably connected to the bed frame.

[0030] This utility model proposes a weighing bed 1000.
[0031] Please see Figure 1 In one embodiment of this utility model, the weighing bed 1000 includes a bed frame 1, a support assembly, and a linkage assembly. The support assembly includes a thigh plate 21, a lower leg plate 22, and a drive member 23. One end of the thigh plate 21 is rotatably connected to the bed frame 1; one end of the lower leg plate 22 is rotatably connected to the end of the thigh plate 21 away from the bed frame 1, and the other end of the lower leg plate 22 is slidably connected to the bed frame 1; the drive member 23 is disposed on the bed frame 1, and the end of the thigh plate 21 away from the lower leg plate 22 is connected to the output end of the drive member 23; the linkage assembly includes a connecting rod 31 and a stop structure 32. One end of the connecting rod 31 is rotatably connected to the lower leg plate 22, and the stop structure 32 is disposed on the bed frame 1 and connected to the end of the connecting rod 31 away from the lower leg plate 22.
[0032] In the technical solution of this utility model, the driving component 23 can drive the thigh plate 21 to move. With the cooperation of the stop structure 32 and the connecting rod 31, the lower leg plate 22 can slide on the bed frame 1 along with the movement of the thigh plate 21, realizing the linkage between the thigh plate 21 and the lower leg plate 22. In this way, there is no need to add an additional driving component 23 to drive the movement of the lower leg plate 22, thereby reducing the production cost of the weighing bed 1000. At the same time, the lower leg plate 22 can be linked with the thigh plate 21. Medical staff do not need to adjust the thigh plate 21 and the lower leg plate 22 separately during operation, simplifying the operation process and making it more convenient for medical staff to operate. The linkage between the thigh plate 21 and the lower leg plate 22 can better adapt to changes in the patient's body posture, avoiding discomfort caused to the patient due to asynchronous movement of the thigh plate 21 and the lower leg plate 22, improving the patient's user experience, and allowing the patient to feel a more comfortable and natural support effect during use.
[0033] The stop structure 32 can consist of a stop block 321 and a baffle, or it can consist of a stop block 321 and a limiting member 322 forming a limiting groove 322a. Please refer to [link / reference]. Figure 2 and Figure 3 In one embodiment of this utility model, the stop structure 32 includes a stop block 321 and a limiting member 322. The limiting member 322 is disposed on the bed frame 1 and forms a limiting groove 322a. The stop block 321 is connected to the connecting rod 31 and abuts against the limiting member 322, limiting it within the limiting groove 322a. Since the linkage between the thigh plate 21 and the calf plate 22 is a reciprocating motion, during the linkage process between the thigh plate 21 and the calf plate 22, the cooperation between the stop block 321 and the limiting groove 322a allows the stop block 321 to slip in the opposite direction, thereby preventing the calf plate 22 from overextending, avoiding potential injury to the patient, and ensuring the patient's safety during use. Therefore, it is preferable that the stop structure 32 consists of a stop block 321 and a limiting member 322 forming a limiting groove 322a.
[0034] Please see Figure 3 In one embodiment of this utility model, the limiting groove 322a includes a limiting section 322a1 and a free section 322a2, with the limiting section 322a1 communicating with the free section 322a2. The limiting section 322a1 is located on the side of the free section 322a2 facing away from the bed frame 1. The length of the free section 322a2 extending along the length direction of the bed frame 1 is greater than the length of the limiting section 322a1 extending along the length direction of the bed frame 1. This structure enables the connecting rod 31 to achieve stable positioning and constraint within the limiting section 322a1 when connected to the stop block 321, ensuring the stability of the lower leg plate 22 in a specific position. The free segment 322a2 provides greater mobility for the connecting rod 31, allowing the calf plate 22 to slide more extensively when needed, thus achieving flexible control over its movement. The free segment 322a2 extends longer than the limiting segment 322a1 along the length of the bed frame 1, enabling the calf plate 22 to achieve a wider range of motion within the free segment 322a2, meeting the diverse needs of different patients for leg support position and angle during use. Simultaneously, the limiting segment 322a1 prevents excessive sliding of the calf plate 22, ensuring its movement within a safe range.
[0035] It is understandable that the slidable connection between the calf board 22 and the bed frame 1 can be achieved by designing a slider on the calf board 22 and a groove on the bed frame 1; or by installing a sliding wheel 33 on the calf board 22. In one embodiment of this utility model, the linkage component further includes a sliding wheel 33, which is rotatably connected to the calf board 22 and slidably connected to the bed frame 1. This design allows the calf board 22 to move primarily through the rolling motion of the sliding wheel 33 during sliding, thus significantly reducing direct friction between the calf board 22 and the bed frame 1. Compared to traditional sliding connections, rolling friction provides less resistance, making the calf board 22 slide more smoothly and steadily, avoiding jamming or wobbling caused by excessive friction. Because the calf board 22 slides more smoothly and steadily, patients experience more natural and comfortable leg support during use. The rolling motion of the sliding wheel 33 better adapts to the natural movement of the patient's legs, making it easier and more comfortable for the patient to adjust their posture. In summary, the preferred method for sliding connection between the lower leg plate 22 and the bed frame 1 is to install sliding wheels 33 on the lower leg plate 22.
[0036] The sliding wheel 33 can be located at any position on the calf board 22. In one embodiment of this invention, the sliding wheel 33 is rotatably connected to the end of the calf board 22 away from the thigh board 21. Installing the sliding wheel 33 at the end of the calf board 22 away from the thigh board 21 ensures that the sliding wheel 33 can still maintain effective contact and sliding with the bed frame 1 when the calf board 22 is folded to a large angle, thereby ensuring that the movement of the calf board 22 is unrestricted and can meet the needs of different medical operations. Therefore, it is preferable that the sliding wheel 33 is connected to the end of the calf board 22 away from the thigh board 21.
[0037] In one embodiment of this invention, the support assembly further includes a hip plate 24, which is disposed on the bed frame 1 and rotatably connected to the end of the thigh plate 21 away from the calf plate 22. The addition of the hip plate 24 enables the weighing bed 1000 to provide more comprehensive body support. In addition to the calf plate 22 and thigh plate 21, the hip plate 24 can provide stable support for the patient's buttocks, thereby better meeting the needs of the patient in different postures, such as lying flat, lying on their side, or in a semi-sitting position, providing comfortable support for the patient.
[0038] In one embodiment of this invention, the support assembly further includes a backrest 25, which is movably connected to the bed frame 1. The addition of the backrest 25 allows the weighing bed 1000 to provide more comprehensive body support, covering the area from the head to the waist. In addition to the calf support 22 and thigh support 21, the backrest 25 provides stable support for the patient's back and upper body, thus better meeting the needs of the patient in different postures, such as lying flat, semi-sitting, and side-lying. Simultaneously, the movable connection between the backrest 25 and the bed frame 1 better adapts to the natural curves of the human body. During use, the patient can freely adjust the back support angle according to their physical condition and comfort requirements, ensuring comfortable support for all parts of the body and reducing discomfort caused by maintaining the same posture for extended periods.
[0039] The weighing bed 1000 also includes multiple wheels 4. In one embodiment of this invention, the weighing bed 1000 includes four wheels 4, each wheel 4 being rotatably connected to the bed frame 1. The design of the wheels 4 allows the weighing bed 1000 to be used not only in fixed locations but also to be quickly moved to other areas when needed. For example, in an emergency, the weighing bed 1000 can be quickly moved to an operating room or emergency room to provide timely treatment support for patients, significantly improving the flexibility of the weighing bed 1000.
[0040] In one embodiment of this utility model, each wheel 4 is a swivel caster. The design of the swivel caster allows the weighing bed 1000 to turn in all directions, and medical staff can easily push the bed in any direction without frequently adjusting the direction of the bed. It is particularly suitable for medical places with limited space, such as narrow corridors, ward doors or operating rooms, and can significantly improve the ease of use of the weighing bed 1000.
[0041] It should be noted that the driving component 23 can be a hydraulic cylinder, a pneumatic cylinder, or a motor. In one embodiment of this invention, the driving component 23 is a motor. The motor provides precise motion control; by adjusting the motor's speed and torque, precise control of the linkage between the thigh plate 21 and the calf plate 22 can be achieved. The motor's power output is also more stable, ensuring that the thigh plate 21 and the calf plate 22 maintain a stable motion state throughout the movement. Therefore, a motor is preferred as the driving component 23.
[0042] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
