Description

Technical Field

[0001] This utility model belongs to the field of nursing equipment technology, and in particular relates to a nursing bed frame and a nursing bed. Background Technology

[0002] With the increasing aging population and rising demands for medical and nursing care, multifunctional nursing beds are being used more and more widely in hospitals, nursing homes, and home care settings. Among them, nursing beds with backrest lifting functions can help patients achieve a semi-recumbent or sitting position, which is beneficial for breathing, eating, sputum expectoration, and rehabilitation training, and has become a basic configuration of modern nursing equipment.

[0003] However, in actual use, traditional backrest-style nursing beds have a prominent safety hazard: when the back support is flipped upward, the patient's center of gravity shifts forward and upward. If there is a lack of effective lateral restraint, the body is very likely to slide to the left or right due to muscle relaxation, loss of consciousness, or unstable posture, or even fall off the bed. This risk is even higher for elderly, postoperative, weak, or neurological patients. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a nursing bed frame with more reliable back protection.

[0005] The objective of this utility model can be achieved through the following technical solution: a nursing bed frame, comprising: The main body of the bed frame includes a backrest bed frame capable of being raised and flipped, the backrest bed frame including a back support and anti-slip supports disposed on both sides of the back support and rotatably connected thereto. A backrest drive unit is provided on the bed frame body. The backrest bed frame is provided with a backrest drive part. The backrest drive part is provided with an anti-slip drive part. The anti-slip drive part and the backrest drive part operate synchronously. The backrest drive part is connected to the output end of the backrest drive unit. The backrest drive part has a first working stroke and a second working stroke. When the backrest drive unit is in the first working stroke, the backrest drive unit is not driven by the backrest bracket, while the anti-slip drive unit is driven by the anti-slip bracket. When the backrest drive unit is in the second working stroke, the backrest drive unit is connected to the backrest support in a transmission connection.

[0006] In the aforementioned nursing bed frame, the backrest drive unit includes a drive swing block disposed at the bottom of the backrest support and capable of rotating relative to it; the anti-slip drive unit includes a drive swing rod disposed at the bottom of the anti-slip support, the end of the drive swing rod abutting against the anti-slip support, and the drive swing rod being fixed to the drive swing block.

[0007] In the aforementioned nursing bed frame, the backrest lifting drive is hinged to the bed frame body, the output end of the backrest lifting drive can perform linear reciprocating movement, and a connecting rod is hinged to its output end. The drive swing block is fixed to the connecting rod, and the drive swing rod is symmetrically arranged at both ends of the connecting rod. The connecting rod is hinged to the backrest lifting bracket.

[0008] In the aforementioned nursing bed frame, the length extension direction of the connecting rod is perpendicular to the back support's back trajectory direction.

[0009] In the aforementioned nursing bed frame, a guardrail is hinged to the anti-slip bracket, and a pull rod is hinged to the guardrail. The other end of the pull rod is hinged to the back support.

[0010] In the aforementioned nursing bed frame, a main frame is also included, and a central bed frame is provided along the length of the main frame. The backrest bed frame is part of the central bed frame. Side-flipping bed frames are symmetrically hinged on both sides of the central bed frame. The anti-slip bed frame is part of the side-flipping bed frame. When the main body of the bed frame is in a flat position, the side-flipping bed frame rests on the main frame. A side-flipping drive is provided on the main body of the bed frame and is driven to connect with the central bed frame.

[0011] In the aforementioned nursing bed frame, a side-turning drive bracket is abutted against the lower part of the central bed frame. The side-turning drive bracket is rotatably connected to the main frame, and a side-turning drive component is provided on the bed frame body. The side-turning drive component is driven to the side-turning drive bracket to cause the side-turning drive bracket to flip.

[0012] In the aforementioned nursing bed frame, a rotating connection part is fixedly provided on the side-turning drive bracket, the bed frame body is connected to the rotating connection part and can rotate relative to it, and a rotating drive component is provided on the side-turning drive bracket and is connected to the bed frame body for transmission.

[0013] In the aforementioned nursing bed frame, a support frame is provided at the bottom of the main frame, and a cross frame is provided between the support frame and the main frame.

[0014] A nursing bed, including the aforementioned anti-slip nursing bed frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) The anti-slip nursing bed frame provided in this application, by setting a back-raising drive unit with a segmented working stroke on the back-raising bed frame, and integrating an anti-slip drive unit that operates synchronously with it on the back-raising drive unit, achieves effective protection for the patient before the back-raising operation, and significantly improves nursing safety and comfort. (2) Specifically, during the first working stroke of the back-lifting drive unit, before it contacts the back support, the anti-slip drive unit simultaneously drives the anti-slip supports on both sides to rotate upwards, turning them from a horizontal state to an inclined upright state, thus forming a semi-enclosed protective structure on both sides of the patient's body. This action is completed before the back-lifting action begins, wrapping and limiting the patient in advance, effectively preventing the risk of lateral slippage or falling off the bed due to changes in the center of gravity during the subsequent back-lifting process.

Detailed Implementation

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0020] like Figures 1-8 As shown, an anti-slip nursing bed frame includes: The bed frame body 100 includes a backrest bed frame 103 capable of being tilted and flipped. The backrest bed frame 103 includes a backrest support 104 and anti-slip supports 105 disposed on both sides of the backrest support 104 and rotatably connected thereto. The backrest drive 106 is mounted on the bed frame body 100. The backrest bed frame 103 is provided with a backrest drive unit 107. The backrest drive unit 107 is provided with an anti-slip drive unit 108. The anti-slip drive unit 108 and the backrest drive unit 107 operate synchronously. The backrest drive unit 107 is connected to the output end of the backrest drive 106. The backrest drive unit 107 has a first working stroke and a second working stroke. When the backrest drive unit 107 is in the first working stroke, the backrest drive unit 107 is not driven by the backrest bracket 104, while the anti-slip drive unit 108 is driven by the anti-slip bracket 105. When the back start drive unit 107 is in the second working stroke, the back start drive unit 107 is connected to the back support 104 in a transmission connection.

[0021] The anti-slip nursing bed frame provided in this application, by setting a back-raising drive unit 107 with a segmented working stroke on the back-raising bed frame 103, and integrating an anti-slip drive unit 108 that operates synchronously with it on the back-raising drive unit 107, effectively protects the patient before the back-raising operation, and significantly improves nursing safety and comfort.

[0022] Specifically, during the first working stroke of the back-lifting drive unit 107, before it contacts the back support 104, the anti-slip drive unit 108 simultaneously drives the anti-slip supports 105 on both sides to rotate upwards, turning them from a horizontal state to an inclined upright state, thus forming a semi-enclosed protective structure on both sides of the patient's body. This action is completed before the back-lifting action begins, pre-wrapping and limiting the patient, effectively preventing the risk of lateral slippage or falling off the bed due to changes in the center of gravity during the subsequent back-lifting process.

[0023] Once the anti-slip bracket 105 has completed its rotation and stabilized in place, the back-lifting drive unit 107 enters its second working stroke. At this time, the back-lifting drive unit 107 establishes a transmission connection with the back support 104, and under the drive of the back-lifting drive component 106, pushes the back support 104 upward to achieve the back support lifting function. Since the patient is effectively restrained by the anti-slip brackets 105 on both sides, the back-lifting process is more stable and safe, avoiding problems such as displacement and slippage caused by the lack of restraint on the patient's body during back-lifting in traditional nursing beds.

[0024] Specifically, the back-raising drive unit 107 includes a drive swing block disposed at the bottom of the back-raising bed frame 103. The drive swing block is transmittedly connected to the output end of the back-raising drive unit 106 and can swing under the drive action. The anti-slip drive unit 108 includes a drive swing rod fixed to the drive swing block. The free end of the drive swing rod abuts against the bottom of the anti-slip bracket 105 and forms a transmission engagement. When the back-raising drive unit 106 is activated, the drive swing block begins to swing. During the first working stroke, the rotation of the drive swing block drives the drive swing rod to move synchronously, pushing the anti-slip bracket 105 to flip upward around its hinge point with the back support 104, making it stand up quickly and forming a semi-enclosed protective structure on both sides of the patient's body, thus limiting and wrapping the patient in advance.

[0025] After the anti-slip bracket 105 completes its flip and stabilizes, the drive block continues to move into the second working stroke. At this time, it begins to contact the back support 104 and apply a thrust, thereby driving the back support 104 to rotate upward and realize the lifting function of the back support.

[0026] Based on the above embodiments, if the drive swing block is driven to lift the back support 104 simply by rotation, the drive swing block would be too long and occupy too much space. Therefore, the lifting drive component 106 is further hinged to the bed frame body 100, and its output end can perform linear reciprocating motion. It is connected to the drive swing block through the hinged connecting rod 109, and the drive swing block and the connecting rod 109 are fixedly connected to form a linkage. At the same time, the drive swing rods of the anti-slip drive part 108 are symmetrically arranged at both ends of the connecting rod 109, and their ends abut against the bottom of the anti-slip bracket 105 to push the anti-slip bracket 105 to flip upward. The connecting rod 109 is hinged to the back support 104, forming a lever structure that can swing around the hinge point.

[0027] When the back-lifting drive 106 is activated and extended, its output end pushes the connecting rod 109 to swing around its hinge point. During the first working stroke, it drives the symmetrically arranged drive swing rods to lift synchronously, thereby pushing the anti-slip supports 105 on both sides to flip upwards synchronously, quickly forming a semi-enclosed protective structure on both sides of the patient's body, achieving pre-wrapping and limiting of the patient, effectively preventing lateral slippage or falls during subsequent back-lifting. As the back-lifting drive 106 continues to extend, the connecting rod 109 swings further into the second working stroke. At this time, the swing of the connecting rod 109 causes the drive swing block to contact the back support 104 and generate thrust, thereby driving the back support 104 to flip upwards, completing the back-lifting action.

[0028] Specifically, two hinge blocks 110 are symmetrically arranged on the connecting rod 109, forming a double-point supported swing connection structure. Furthermore, the movable end of the driving swing rod is provided with an abutment roller 111, which rolls in contact with the anti-slip bracket 105. When the connecting rod 109 swings, the driving swing rod applies a thrust to the anti-slip bracket 105 through the abutment roller 111, causing it to flip upwards.

[0029] The connecting rod 109 is arranged perpendicular to the lifting trajectory, serving as a lateral linkage that evenly transmits the thrust of the lifting drive 106 to both ends. When the connecting rod 109 swings under the drive, its two sides move symmetrically with consistent swing angles, ensuring complete synchronization of the displacement and action time of the left and right drive swing arms. This avoids differences in left and right stroke, uneven thrust, or unilateral lag caused by the tilted arrangement of the drive components or the skewed direction of force, ensuring that the anti-slip brackets 105 on both sides can synchronously and smoothly flip upwards before lifting, forming a symmetrical semi-enclosed protective structure, effectively preventing the patient from shifting or slipping due to failure to stand up on one side in time.

[0030] like Figure 4 As shown, a guardrail 200 is provided on the anti-slip bracket 105, and a tie rod 201 is hinged to the guardrail 200. Specifically, a first connecting part 202 and a second connecting part 203 are hinged to both ends of the tie rod 201. The first connecting part 202 is also hinged to the back bracket 104, and the second connecting part 203 is also hinged to the anti-slip bracket 105. This causes the hinge points between the tie rod 201, the anti-slip bracket 105, and the first connecting part 202 and the second connecting part 203 to form a parallelogram linkage mechanism. During the upward rotation of the anti-slip bracket 105 around its axis of rotation with the back bracket 104, due to the geometric characteristics of the parallelogram mechanism, the guardrail 200 always maintains its initial vertical posture and will not tilt or deflect with the swing of the anti-slip bracket 105.

[0031] It is worth mentioning that a connecting frame 204 is fixedly installed on the second connecting part 203, and the guardrail 200 is inserted and fixed on the connecting frame 204, and the insertion distance of the guardrail 200 on the connecting frame 204 is adjustable.

[0032] like Figures 6-7 As shown, the anti-slip nursing bed frame provided in this application not only has a safe and reliable backrest lifting function and anti-slip protection mechanism, but also integrates an overall side-turning function, realizing multi-position coordinated adjustment, which significantly improves the comprehensive performance and clinical applicability of the nursing bed.

[0033] Specifically, it also includes a main frame 300, with a central bed frame 101 arranged along the length of the main frame 300. A backrest bed frame 103 serves as the front end of the central bed frame 101, enabling independent lifting of the back support. Side-folding bed frames 102 are symmetrically hinged on both sides of the central bed frame 101. These side-folding bed frames 102 overlap the main frame 300 when the bed is laid flat, forming stable support. Anti-slip brackets 105, as part of the side-folding bed frame 102, become one of the execution units for the side-folding movement. It is worth mentioning that other parts of the side-folding bed frame 102 (such as the leg bed frame) are also equipped with guardrails 200, connected to the corresponding bed frames via a parallelogram linkage mechanism. Because the length of the pull rods 201 is fixed and the hinge relationship is clear, their existence creates a rigid constraint on the movement trajectory of the side-folding bed frame 102: the side-folding bed frame 102 can only fold inward relative to the central bed frame 101 (i.e., rotate towards the center of the bed), and cannot open outward or undergo torsional displacement.

[0034] The bed frame body 100 is also equipped with a side-flipping drive unit 301, the output end of which is driven by the central bed frame 101. By pushing the central bed frame 101 to deflect, the side-flipping bed frame 102 is driven to rotate, thereby realizing the function of flipping the bed frame to the left or right. When the bed frame is in a flat position, the two side-flipping bed frames 102 overlap the main frame 300 to form a complete support plane. When performing the side-flipping operation, the side-flipping drive unit 301 pushes the central bed frame 101 to tilt to one side. At this time, the side-flipping bed frame 102 on the driven side cannot rotate downward and remains stationary because its bottom is in contact with the main frame 300 and is physically limited. A side-flipping angle is formed between the central bed frame 101 and the side-flipping bed frame 102. The side-flipping bed frame 102 on the other side is pulled by the pull rod 201 and follows the central bed frame 101, and is still located in the same plane direction.

[0035] The side-tilting drive bracket 302 is located below the central bed frame 101, with both ends rotatably connected to the main frame 300 of the bed frame body 100, forming a stable rotation fulcrum; one end is hinged to the output end of the side-tilting drive component 301, constituting a push-pull drive unit. The side-tilting drive component 301, through its telescopic movement, drives the side-tilting drive bracket 302 to reciprocate around its hinge point with the frame, thereby pushing the central bed frame 101 to tilt to the left or right, achieving overall side-tilting control. When the drive component extends, it pushes the side-tilting drive bracket 302 to swing, causing the central bed frame 101 to tilt to one side, achieving a leftward tilt. When the drive unit retracts, it pulls the side-tilting drive bracket 302 to swing in the opposite direction, causing the central bed frame 101 to tilt to the other side, thus achieving a rightward tilt.

[0036] like Figure 8 As shown, based on the aforementioned functions of backrest lifting, anti-slip protection, and overall side-tipping, this application further realizes the controllable rotation function of the bed frame body 100 in the transverse plane (i.e., in the horizontal plane, around the vertical axis).

[0037] Specifically, a rotating connection part 400 is fixedly provided on the main frame 300. The bed frame body 100 is rotatably connected to the main frame 300 through this rotating connection part 400, enabling it to rotate left or right relative to the main frame 300 in the horizontal plane around the vertical axis. This rotating connection part 400 serves as a rotational support structure and can take the form of a slewing bearing, a central shaft, or a low-friction slewing hinge, ensuring that the bed frame body 100 can still rotate smoothly under load.

[0038] A rotary drive component 401 is hinged to the main frame 300, with its output end being a reciprocating linearly movable push rod. This output end is connected to the end of a connector 402 on the central bed frame 101. When the rotary drive component 401 operates, its linear thrust acts on the connector 402, generating a torque around the vertical axis, thereby driving the bed frame body 100 to rotate in the transverse plane. A telescopic rod 403 is also provided on the bed frame body 100, with one end hinged to the bed frame body 100 and the other end connected to the other end of the connector 402. This telescopic rod 403 extends and retracts synchronously during the rotation of the central bed frame 101, not only acting as a guide component to constrain the motion trajectory and prevent swaying or jamming, but also working in conjunction with the rotary drive component 401 to achieve balanced torque application, ensuring a smooth and synchronous rotation process.

[0039] This application further includes a bed frame height adjustment mechanism. Specifically, a support frame 500 is provided at the bottom of the main frame 300. The support frame 500 is connected to the main frame 300 via a cross frame 501, with its upper and lower ends hinged to the support frame 500 and the bed frame body 100, respectively. When the cross frame 501 is extended or retracted, it can drive the bed frame body 100 to rise and fall as a whole, thereby achieving continuous adjustment of the bed surface height.

[0040] A tension drive component 502 (such as an electric push rod, hydraulic cylinder or pneumatic cylinder) is provided on the support frame 500, which pushes the cross frame 501 to unfold or retract through linear telescopic motion.

[0041] A nursing bed, including the aforementioned anti-slip nursing bed frame.
