Description

Technical Field

[0001] This utility model relates to the field of medical and nursing technology, and in particular to a multifunctional hospital bed. Background Technology

[0002] In the field of medical care, for patients who are unable to get out of bed due to illness, postoperative recovery, or other reasons, daily activities such as eating, reading, and entertainment must be completed in bed. In this context, medical tables become an indispensable assistive device.

[0003] However, existing medical tabletops generally suffer from inconvenience in operation and functional limitations. For example, most tabletops use a stackable or simple snap-fit ​​connection structure, requiring medical staff or family members to manually drag and adjust their position. This process is prone to uneven force, causing the tabletop to wobble or even tip over, posing risks such as spilled food or damage to electronic devices. In contrast, some improved designs, such as medical nursing tabletops with limiting structures, improved medical beds equipped with tabletops, and improved medical bedside tables, all improve the stability and safety of the tabletop through specific designs, thereby improving the user experience. Some products rely solely on gravity or single-point support for fixation, meaning that even slight touches by the patient can cause displacement, severely impacting the user experience and potentially posing a risk of injury. To address these issues, a multi-functional hospital bed is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a multifunctional hospital bed.

[0005] To achieve the above objectives, the present invention has designed and adopted the following technical solution:

[0006] A multifunctional hospital bed includes a bed frame, a movable frame on the bed frame, a limiting frame slidably passing through the movable frame via an elastic mechanism, a limiting groove corresponding to the limiting frame on the outer wall of the bed frame, a movable plate on the movable frame via a support mechanism, a support plate fixedly mounted on the movable frame, a drive motor mounted on the support plate, a battery assembly cooperating with the drive motor on the movable frame, the drive motor connected to the movable frame via a rotation mechanism, and the movable frame connected to the bed frame via a transmission mechanism.

[0007] The preferred embodiment is that the elastic mechanism consists of a spring sleeved on the outside of the limiting frame rod, and a fixing ring is installed on the limiting frame rod. The two ends of the spring are tightly connected to the outer walls of the movable frame and the fixing ring, respectively.

[0008] Preferably, the support mechanism includes multiple support frames fixedly mounted on the movable frame, with the upper and lower support frames evenly spaced apart.

[0009] Preferably, the rotating mechanism includes a first gear rotatably mounted on a support plate and fixedly connected to the output shaft of a drive motor, and a second gear rotatably mounted on the movable frame and meshing with the first gear.

[0010] In the design of the transmission mechanism, the rack is securely mounted on the bed and precisely meshes with the second gear.

[0011] The outer wall of the limit frame is fitted with a fixed protective sleeve, which provides safe protection for the drive motor, while the drive motor is cleverly placed between the limit frame and the movable frame.

[0012] The beneficial effects of this utility model are:

[0013] 1. The system uses Bluetooth remote control and rack and pinion transmission to achieve electric horizontal movement of the movable frame. The position of the bed can be accurately adjusted without manual pushing, making it convenient for medical staff to approach the patient for nursing operations or to flexibly arrange the ward space.

[0014] 2. The double-layer storage design of the movable shelf and movable board, combined with the height-adjustable movable board, allows for the categorization and storage of frequently used and infrequently used items, meeting diverse storage needs; when not in use, the movable shelf can be quickly disassembled and stored, significantly reducing the space occupied by the hospital bed and facilitating ward organization and transportation.

[0015] 3. The concealed rack and rubber protective cover prevent patients and medical staff from being scratched or bumped by protruding parts; at the same time, the protective cover can prevent the drive motor from being damaged by external forces, thus improving the overall safety and durability of the hospital bed.

[0020] The technical solutions in the embodiments of this utility model will be described in detail below with reference to the accompanying drawings, clearly and comprehensively demonstrating their details. It should be noted that the mentioned embodiments are merely examples and do not represent the entire scope of this utility model.

[0021] Reference Figure 1-3 A multifunctional hospital bed includes a bed frame 1, a movable frame 2 on the bed frame 1, a limiting frame 8 slidably passing through the movable frame 2 via an elastic mechanism, and a limiting groove 6 corresponding to the limiting frame 8 on the outer wall of the bed frame 1. A movable plate 4 is mounted on the movable frame 2, and the movable plate 4 is fixed by a support mechanism. A support plate 11 is also mounted on the movable frame 2, and a drive motor 12 is mounted on the support plate 11. A battery assembly 5 mounted on the movable frame 2 powers the drive motor 12. The drive motor 12 is connected to the movable frame 2 via a rotating mechanism, and the movable frame 2 is connected to the bed frame 1 via a transmission mechanism.

[0022] The elastic mechanism mainly consists of a spring 10, which is sleeved on the outside of the rod of the limiting frame 8. A fixing ring 9 is fixed to the rod of the limiting frame 8, and the two ends of the spring 10 are connected to the outer walls of the movable frame 2 and the fixing ring 9, respectively. The elastic potential energy provided by the spring 10 enables the dragging of the limiting frame 8, ensuring that its rod is within the limiting groove 6. In this state, the movable frame 2 cannot move vertically relative to the bed 1, and as shown in the figure, the movable frame 2 has a U-shaped design, with its outer wall sliding in contact with the outer wall of the bed 1. The movable frame 2 also cannot move horizontally relative to the bed 1.

[0023] The support mechanism includes multiple support frames 3 fixedly mounted on the movable frame 2, with equal spacing between the upper and lower support frames 3. Each layer is equipped with four support frames 3, and the four corners of the movable plate 4 are securely embedded in these four support frames 3. The overall structure is divided into upper and lower layers, which allows for flexible adjustment of the installation height of the movable plate 4.

[0024] The movable board 4 is set up in conjunction with the movable shelf 2, and items can be placed on the upper surface of the movable shelf 2 and the upper surface of the movable board 4, providing a large placement space.

[0025] The rotating mechanism includes a first gear 13 rotatably mounted on the support plate 11 and fixedly connected to the output shaft of the drive motor 12, and a second gear 14 rotatably mounted on the movable frame 2, meshing with the first gear 13. The transmission mechanism includes a rack 7 fixedly mounted on the bed 1, which meshes with the second gear 14. Due to the addition of the second gear 14, the rack 7 is cleverly concealed at the bottom of the bed 1, avoiding any safety hazards caused by its extension, while also ensuring that the first gear 13 is not exposed, thus preventing accidental contact by personnel.

[0026] The size of the second gear 14 should be set according to the actual situation, ensuring that it does not affect the vertical rise of the movable frame 2 and its separation from the bed 1.

[0027] A protective sleeve is fixedly installed on the outer wall of the limit frame 8, and the drive motor 12 is located between the limit frame 8 and the movable frame 2. Although not shown in the figure, the protective sleeve is made of rubber, which can effectively prevent people from colliding with the limit frame 8 when walking and also provide additional protection for the drive motor 12 to prevent it from being damaged.

[0028] The battery assembly 5 is a rechargeable battery, which is electrically connected to the drive motor 12. The drive motor 12 is equipped with a mature Bluetooth remote control, which can control the start and forward / reverse rotation of the drive motor 12.

[0029] Components not specifically described in this utility model are all standard parts and can be purchased commercially. The connection methods of each component follow mature solutions in the prior art, therefore specific details are omitted. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0030] In use, the battery assembly 5 supplies power to the drive motor 12. The motor 12 can be started and rotated forward and backward via a Bluetooth remote control. After starting, the drive motor 12 rotates the first gear 13, which meshes with the second gear 14, transmitting power to the second gear 14. The second gear 14 meshes with a rack 7 fixed to the bottom of the bed frame 1. Under the transmission action of the above components, the movable frame 2 can move horizontally relative to the bed frame 1, thus moving closer to or further away from the user lying on the bed frame 1. It can be moved away from the user when not in use and closer to the user when in use.

[0031] The combination of movable shelf 2 and movable panel 4 provides ample storage space. Movable shelf 2 is suitable for storing frequently used items, while movable panel 4 is used to store less frequently used items. If there is insufficient space above movable panel 4, movable panel 4 can be lowered to increase storage space.

[0032] To store the movable frame 2, manually drag the limiting frame 8 outwards. The limiting frame 8 stretches the spring 10, causing its rod to disengage from the limiting groove 6. At this point, the limitation on the movable frame 2 is released, and the movable frame 2 can be lifted upwards and separated from the bed body 1. Under normal use, the spring 10 uses its elastic potential energy to cause the limiting frame 8 to return to its original position, with its rod tightly engaged in the limiting groove 6, effectively preventing the movable frame 2 from moving in the vertical and horizontal directions and ensuring the stability of the overall structure.

[0033] The rack 7 is secured by a bolt assembly, and disassembly can be performed simply by loosening the bolt assembly.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
