Description

Technical Field

[0001] The present application relates to the field of electric beds, and in particular to an electric bed frame. Background Art

[0002] In the existing technology, electric bed frames, as a device with rich functions and the ability to enhance user comfort, have been widely used in various scenarios, especially in environments such as homes and hospitals where patients need to stay in bed for long periods of time. The core function of an electric bed frame is to use an electric motor to drive the mechanical structure, allowing the bed to be adjusted to different angles, such as raising the back, lifting the legs, and turning sideways, thereby helping users adjust their posture according to their needs during rest, treatment, or nursing. This type of electric bed frame is particularly important in medical scenarios. It can not only alleviate the discomfort caused by a single posture when patients are in bed for a long time, but also help caregivers provide care services to patients more efficiently and reduce the heavy physical labor of manually adjusting the bed position.

[0003] The basic driving method of existing electric bed frames mainly relies on electric motors to drive multiple joints. The rotation of the motor drives different parts of the bed frame to adjust posture. This technology has played a significant role in improving user comfort, convenience, and medical care efficiency. However, while existing technology can meet some basic functional requirements, it still has some obvious defects and limitations in actual use.

[0004] First, the noise problem of electric bed frames is particularly prominent during operation. Existing bed frame connecting shafts lack a silent design, resulting in noticeable mechanical friction and vibration during movement. This noise is particularly irritating at night or in environments where quiet is required. It not only disrupts the user's rest and sleep, but can also disturb other patients in the ward and other family members, seriously affecting the quietness and comfort of the overall living or nursing environment.

[0005] Secondly, existing electric bed frames lack stability during large-scale adjustments, especially during rollovers or rapid posture changes, causing the bed to easily wobble or shift. This lack of stability is primarily due to the structural design. The support system of existing bed frames often fails to provide sufficient balance and support during rapid movements, causing the bed to lose balance when its center of gravity shifts, resulting in wobble or tilt. This not only affects the user's comfort and discomfort, but also poses a potential safety hazard, especially for elderly people with limited mobility, critically ill patients, or those recovering from surgery. Bed frame shaking can cause them to lose control of their posture, increasing the risk of falls or slips.

[0006] The causes of these problems can be attributed to the limitations of existing electric bed frames in design and manufacturing. Most electric bed frames use a traditional motor drive system. Although this system can achieve basic posture adjustment, its structure is relatively simple and lacks effective control of motor noise and shock absorption. Traditional motor design fails to take into account the need to reduce noise from motor vibration, resulting in the electric bed frame generating a lot of noise during movement. During large-scale movements such as rollover, the balance support design of the bed is relatively simple and fails to fully consider the impact of the center of gravity shift. The support structure is also relatively simple and cannot cope with the complex posture change requirements, resulting in insufficient stability of the bed.

[0007] Therefore, in view of these shortcomings, it is of great significance to develop a quieter and more stable electric bed frame. Utility Model Content

[0008] The purpose of this application is to overcome at least one of the shortcomings of the existing technology and provide an electric bed frame that uses a new transmission structure to significantly improve the comfort of the bed frame, reduce noise, and enhance its stability during complex movements. This not only enhances the user experience but also provides safer and more reliable support in specific scenarios such as medical care.

[0009] To achieve the above-mentioned purpose, the present application discloses an electric bed frame, which includes a structural frame, a driving assembly installed in the structural frame, and a multi-folding bed board connected to the driving assembly, wherein:

[0010] The driving assembly comprises an independently rotating base, a front movable part and a rear movable part which are mounted on the base and work independently;

[0011] The multi-fold bed board includes multiple modules in the width direction and multiple modules in the length direction;

[0012] The modules in the width direction and the length direction are hingedly connected by hinge axes. The hinge axes in the width direction are arranged in the width direction so that the modules can be folded relative to each other around the hinge axes in the width direction. Meanwhile, the hinge axes in the length direction are arranged perpendicular to the width direction so that the modules can be deflected relative to each other around the hinge axes in the length direction.

[0013] The two ends of the structural frame in the longitudinal direction are respectively provided with central guide wheels for realizing the deflection and deformation of the multi-fold bed board in the width direction. The central guide wheels cooperate with the multi-fold bed board, and the central guide rail serves as a non-fixed deflection axis to realize the flexible deflection of the multi-fold bed board in the width direction;

[0014] A plurality of side guide wheels are further provided on both sides of the width direction of the structural frame. The side guide wheels cooperate with the modules of the multi-fold bed board near the edge. Through the cooperation of the side guide wheels and the modules, when the multi-fold bed board deflects in the width direction, the multi-fold bed board is provided with stable guidance and support, ensuring that it remains stable during the deflection process, thereby improving the overall working stability and use reliability of the multi-fold bed board.

[0015] At least one module of the multi-fold bed board is fixed on a horizontal base, and the multi-fold bed board is driven by a driving assembly to deflect in the length / width direction to complete the deformation of the multi-fold bed board;

[0016] In some embodiments, the multi-fold bed board is divided into three sections in the width direction and four sections in the length direction, and is formed by 12 modules hinged together.

[0017] In some embodiments, the driving assembly includes a base, a base hinged on the base, a first driving member driving the base to deflect around a hinge axis, an upper movable arm hinged at the front end of the base to form a front movable part, a second driving member driving the upper movable arm to deflect in a vertical direction around the hinge axis, a lower movable arm hinged at the rear end of the working frame to form a rear movable part, a third driving member driving the lower movable arm to deflect in a vertical direction around the hinge axis, and a linkage arm installed at the rear end of the base and coordinated with the lower movable arm; the linkage arm is hingedly coordinated with the module of the multi-fold bed board near the rear end, and the front ends of the upper movable arm and the lower movable arm are provided with working guide wheels cooperating with the multi-fold bed board. When the upper movable arm and / or the lower movable arm are deflected, the working guide wheels push the modules in the multi-fold bed board to move, and then the modules are linked to the remaining modules to move synchronously to complete the deformation of the multi-fold bed board.

[0018] Furthermore, the module in the multi-fold bed board includes an outer frame, a structural net installed on the outer frame, and a structural rod provided on the module that cooperates with the working guide wheel. When working, the working guide wheel is opposite to the structural rod to push the module to move.

[0019] In some embodiments, a silent ring is installed on the hinge shaft to prevent direct contact between metal parts.

[0020] Compared with the prior art, this application has at least one of the following beneficial effects:

[0021] 1. Effectively reduce noise: The utility model avoids direct contact between metal parts by arranging a silent ring on the hinge shaft, thereby greatly reducing the noise generated by the multi-fold bed board during movement, especially at night or in a quiet environment, thereby improving the user's comfort experience.

[0022] 2. Improve working stability: By setting central guide wheels and side guide wheels at both ends of the structural frame and using them in conjunction with the modules of the multi-fold bed board, stable guidance and support are achieved for the multi-fold bed board when it is deflected and deformed in the width direction, ensuring the stability and safety of the multi-fold bed board during use and avoiding shaking or instability.

[0023] 3. Flexible multi-angle adjustment: The multi-folding bed board of the electric bed frame of this utility model can be folded and deflected in the width and length directions respectively. Through the flexible adjustment of the driving components, multi-angle posture changes can be achieved to meet the user's posture needs in different scenarios. It is particularly suitable for medical and nursing scenarios.

[0024] 4. Optimized drive system: Through the design of an independently rotating horizontal base and multiple movable arms, the utility model can achieve synchronous movement of different parts of the bed frame. The drive system is not only flexible in movement, but also can improve the overall coordination of the bed board through the cooperation of the linkage arms, avoiding the incoordination problems that may be caused by the individual movement of each module.

[0025] 5. Reliable structure and easy maintenance: The structural design between the hinge shaft and the module of this electric bed frame is simple and efficient. At the same time, the cooperation between the guide wheel and the hinge shaft reduces the friction and wear of the equipment, extends the service life of the bed frame, and is easy to maintain.

[0026] The above-listed beneficial effects are not exhaustive and other potential beneficial effects and detailed technical implementations will be further disclosed in the examples or other description sections of this application. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] As used in this specification, the singular forms "a," "an," "said," and "the" include the plural forms unless otherwise expressly stated. The words "include," "comprise," and "contain" as used in this specification indicate the presence of the claimed features, but do not exclude the presence of one or more additional features. The word "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0037] like Figure 1 、 2 As shown, this embodiment discloses an electric bed frame, and the entire bed frame consists of a structural frame 1, a driving component 2 installed in the structural frame 1, and a multi-folding bed board 3 connected to the driving component 2.

[0038] The core of the bed frame design is to achieve flexible folding and deflection of the multi-fold bed board 3 in the width and length directions through the multi-directional adjustment of the drive component 2 to adapt to different usage scenarios, especially the need for diversified posture adjustment in medical care scenarios.

[0039] Specifically, in this embodiment, the structural frame 1 is constructed of high-strength steel to ensure sufficient rigidity and load-bearing capacity for the bed frame. The structural frame 1 primarily comprises a main frame 101, central guide wheels 102, and side guide wheels 103. Central guide wheels 102 are positioned at each end of the main frame 101 in the structural frame 1 along its length. These two central guide wheels 102 serve as non-fixed deflection axes, enabling the multi-fold bed board 3 to flexibly deflect and deform in the width direction around these central guide wheels 102. The central guide wheels 102 are rubber wheels.

[0040] It should be understood that, depending on actual use requirements, the center guide wheel 102 and the side guide wheels 103 can also be made of other materials.

[0041] In this embodiment, the multi-fold bed board 3 is composed of a plurality of modules 301, wherein the width direction and the length direction are respectively divided into three sections and four sections, and a total of 12 modules 301 are connected by hinge shafts. These hinge shafts are made of high-strength steel and are precisely processed to ensure that each module 301 can maintain a smooth transition when folding and deflecting. The setting direction of the hinge shaft is along the width and length directions, allowing the multi-fold bed board 3 to be independently deflected in the width and length directions around these hinge shafts. At the same time, a silent ring made of high-strength rubber material is installed on the hinge shaft (not shown in the figure). The silent ring can not only effectively reduce the metal friction between the modules, but also absorb some vibrations during movement, further reducing noise and improving the comfort of the bed frame.

[0042] In the above structure, it needs to be understood that the side guide wheel 103 and the hinged structure of the multi-fold bed board 3 form a synergistic effect, especially when the multi-fold bed board 3 is deflected and deformed in the width direction, the side guide wheel 103 can effectively guide the movement of the edge part of the multi-fold bed board 3 to avoid track deviation or jamming caused by deformation of the board body.

[0043] In terms of specific functions, the side guide wheels 103 primarily provide precise guidance, ensuring that the multi-folding bed board 3 remains on its intended trajectory during angle adjustment or deformation, preventing deviation or jamming. This guidance is crucial for achieving multi-angle adjustment of the bed frame. This is especially true during complex maneuvers such as back raising, leg lifting, and side rollovers. The side guide wheels 103, in close coordination with the module 301, guide the board for smooth and stable deflection across its width, ensuring unimpeded movement of the entire bed frame.

[0044] Secondly, the side guide wheels 103 also provide stable support. When the bed frame undergoes significant posture adjustments, especially during rollovers or rapid posture changes, the center of gravity of the bed will shift significantly with the movement of the deck. At this time, the side guide wheels 103, by supporting and guiding the edges of the bed, can effectively offset the instability caused by this center of gravity shift, preventing the bed from shaking or tilting. This stable support is particularly important for users who require long-term bed rest or undergoing medical treatment. It ensures that they will not feel uncomfortable or startled by sudden shaking when using the electric bed frame, reducing the risk of falls or slips. It is especially safe for patients with limited mobility, the elderly, or those recovering from surgery.

[0045] In the specific structure of the multi-fold bed board 3, among the multiple modules 301 in the multi-fold bed board 3, according to different positions, in the module 301 located in the middle, from the head of the bed to the foot of the bed, there are respectively a module 301a for supporting the head and back, a module 301b for supporting the waist and buttocks, a module 301c for supporting the thighs, and a module 301d for supporting the calves and feet.

[0046] More specifically, the outer frame 3001 of each module 301 is made of steel. This provides structural support for the module, capable of bearing the weight of the bed in various positions and ensuring stability when the module 301 is folded and unfolded. The outer frame 3001 is mechanically secured to the hinge axis, ensuring a secure connection between the modules 301 and allowing the modules to rotate around the hinge axis when needed.

[0047] The structural net 3002 is installed within the outer frame 3001 and forms the primary surface of the multi-folding bed board 3. Made from high-strength nylon fiber or steel wire, the structural net 3002 ensures excellent breathability and effectively supports the user's weight, while also providing a certain degree of elastic cushioning. The structural net 3002 is securely attached to the outer frame 3001 at multiple points, ensuring it will not loosen or deform during movement of the modules 301.

[0048] It should be understood that the structural net 3002 can be replaced with plates or support rods according to actual needs.

[0049] In addition, if Figure 1 As shown, in the modules 301a and 301d of the multi-folding bed board 3, the following Figure 5The structural rods 3003 shown enhance the module's strength. Made of high-strength steel, they are vertically positioned along the inner frame 3001 of module 301 and connected to the outer frame 3001 fixtures, ensuring the module's strength under load. These rods not only reinforce the module's structure but also provide a stable support point for longitudinal movement, ensuring smoother folding and unfolding.

[0050] In terms of the driving component 2, the driving component 2 is the core component of the electric bed frame, and is responsible for achieving precise adjustment of the multi-folding bed board 3 in the length direction and the width direction.

[0051] Specifically, the driving assembly 2 includes a base frame 206 , a base 201 , an upper movable arm 202 , a lower movable arm 203 , a working guide wheel 204 , and a linkage arm 205 .

[0052] The base frame 206, located near the center and front of the structural frame 1, serves as the load-bearing and support platform for the entire drive assembly 2. Made of high-strength steel, the base frame 206 provides sufficient rigidity and strength to prevent the drive assembly 2 from deforming or shifting during bed frame adjustment. A first drive unit 207 is mounted on the base frame 206. The base 201 is designed to rotate about a hinged axis with the base frame 206, driven by the first drive unit 207 to achieve the turning motion of the multi-folding bed board 3.

[0053] In the above structure, the base 201 is connected to the Figure 1 The module 301b shown is fixedly connected to realize the fixed connection between the multi-fold bed board 3 and the driving assembly 2, so as to meet the need for the multi-fold bed board 3 to fold sideways during turning over.

[0054] In this embodiment, the upper movable arm 202 is a moving component mounted at the front end of the base 201. It is primarily used to drive the up and down movement of the front module 301 of the multi-fold bed board 3, thereby performing the back-lifting operation. The upper movable arm 202 is connected to the base 201 via a second drive mechanism 208, which drives the upper movable arm 202 to vertically deflect and adjust about the hinge axis. A working guide wheel 204 is mounted at the end of the upper movable arm 202. This working guide wheel 204 cooperates with the structural rod 3003 within the module 301a near the front of the multi-fold bed board 3, ensuring precise control of the movement of the module 301 during movement.

[0055] The lower movable arm 203 is similar to the upper movable arm 202 and is installed at the rear end of the base 201. It is mainly used to control the up and down deflection of the rear module 301c of the multi-folding bed board 3. Unlike the upper movable arm 202, the lower movable arm 203 is connected to the base 201 through a third drive device 209. At the same time, in order to cooperate with the lower movable arm 203, a linkage arm 205 is also provided. The purpose of the linkage arm 205 is to drive the module 301d to move in conjunction when the lower movable arm 203 moves, so that it forms a Figure 4 The form shown.

[0056] It should be understood that, in the above structure, the first driving device 207 , the second driving device 208 and the third driving device 209 are all electric telescopic rods.

[0057] In the above structure, the rubber working guide wheels 204 are installed at the ends of the upper and lower movable arms 202 and 203, and engage with the structural rods 3003 of the multi-fold bed board 3. The main function of the working guide wheels 204 is to convert the movement of the movable arms into the movement of the modules 301 in the multi-fold bed board 3.

[0058] During use, the drive assembly 2 enables the multi-folding bed board 3 to be flexibly adjusted in both width and length. The folding and deflection angles of the bed board can be precisely adjusted to the user's needs. For example, the bed board can be adjusted in width to adjust the user from a flat to a semi-recumbent position, or adjusted in length to elevate the user's legs, providing better postural support for rest or recovery.

[0059] More specifically, during the operation of the electric bed frame, various components work together to achieve flexible adjustment of the multi-fold bed board.

[0060] The electric bed frame receives commands from the user. Users can select different posture adjustment options via a control panel or remote control. Upon receiving the command, the corresponding electric telescopic rod is activated. The electric telescopic rod is a linear actuator that can be driven by an electric motor to achieve length changes. Its telescopic movement determines the adjustment range of the bed board. The electric telescopic rod generally consists of a motor, gears, a screw, and a telescopic arm. The motor drives the screw to rotate, and the telescopic arm moves linearly along the screw. The electric telescopic rod can move in both extension and retraction directions.

[0061] The electric telescopic rod of the second driving device 208 is responsible for adjusting the front part of the multi-folding bed board 3 (for example, the area where the user's upper body is located). When the user selects the "back lift" function, the electric telescopic rod at the front begins to extend, pushing the front module 301 upward, gradually adjusting the front end of the bed board from a horizontal state to a horizontal position. Figure 3The telescopic length and speed of the electric telescopic rod are precisely controlled by the control system, ensuring smooth movement and low noise.

[0062] The electric telescopic rod of the third driving device 209 is responsible for adjusting the rear end of the multi-fold bed board 3 (for example, raising the legs). When the user selects the leg raising function, the rear end electric telescopic rod begins to extend, driving the rear end of the multi-fold bed board 3 to gradually rise, thereby raising the legs.

[0063] The widthwise deflection of the multi-folding bed board 3 is achieved through the precise movement of the electric telescopic rod of the first drive unit 207. For example, when the user selects the side-tilt function, the electric telescopic rod operates, telescoping and retracting to achieve lateral deflection of the bed board. At this time, the central guide wheel 102 around which the multi-folding bed board rotates ensures smooth movement and controllable angles.

[0064] After the bed is adjusted, the electric telescopic rod stops extending and enters standby mode, locking the bed's angle and position to prevent accidental movement during use. The user can maintain the adjusted position for rest or treatment, while the control system continuously monitors the bed's status to ensure stability and safety.

[0065] Although exemplary embodiments of the present disclosure have been described, it will be understood by those skilled in the art that various changes and modifications may be made to the exemplary embodiments of the present disclosure without departing substantially from the spirit and scope of the present disclosure. Therefore, all such changes and modifications are intended to be within the scope of protection of the present disclosure as defined by the appended claims.
