Description

Technical Field

[0001] This invention relates to the field of nursing bed technology, and in particular to the structure of medical nursing beds and medical nursing beds. Background Technology

[0002] Nursing beds are generally powered beds, which can be divided into electric or manual nursing beds. They are designed according to the patient's bedridden lifestyle and treatment needs, and are designed to allow family members to accompany the patient. They have multiple nursing functions and operation buttons, and are insulated and safe to use.

[0003] A nursing bed typically includes a frame, a backrest lift, a leg flexion lift, and two drive mechanisms. The backrest lift and leg flexion lift are both pivotally connected to the frame. One drive mechanism drives the backrest lift to rotate upward to assist the patient in raising their back, and the other drive mechanism drives the leg flexion lift to rotate upward to assist the patient in bending their legs.

[0004] The drawback of the existing technology is that, since patients usually use the back-raising function and the leg-bending function separately, driving the back-raising component and the leg-bending component to rotate upwards through two corresponding drive devices would result in high production costs, so improvements are urgently needed. Summary of the Invention

When assisting a patient to sit up, the drive mechanism selects and engages the backrest lifting component, enabling it to rotate upwards relative to the frame. After the patient finishes sitting up, the drive mechanism gradually releases its hold on the backrest lifting component, which, under its own weight and the patient's back support, rotates downwards relative to the frame and remains in contact with the drive mechanism until it reaches a horizontal position. Similarly, when assisting a patient to bend their legs, the drive mechanism selects and engages the leg bending component, enabling it to rotate upwards relative to the frame. After the patient finishes bending their legs, the drive mechanism gradually releases its hold on the leg bending component, which, under its own weight and the patient's legs support it, rotates downwards relative to the frame and remains in contact with the drive mechanism until it reaches a horizontal position. This design allows both backrest lifting and leg bending functions to be achieved with a single drive mechanism, effectively reducing production costs. Attached Figure Description

Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0055] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0056] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0057] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

[0059] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0060] This invention proposes a medical care bed structure in which either a backrest support or a leg flexion support can be selectively rotated upwards relative to the frame via a drive device, assisting the patient in raising their back or flexing their legs. This design allows both backrest raising and leg flexion functions to be achieved through a single drive device, thereby effectively reducing production costs.

[0061] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the medical care bed structure 1000 includes: a frame 100, a backrest 200, a leg bending component 300, and a drive device 400.

[0062] The frame 100 provides mounting positions for the backrest 200 and the curved leg 300. The frame 100 can be formed in various ways; it can be assembled from multiple rod-shaped structural components, or from multiple plate-shaped structural components. It can also be integrally formed using methods such as casting or die casting; no specific limitation is made here. The shape of the frame 100 can be square, circular, or other shapes; no specific limitation is made here.

[0063] The back support 200 supports the patient's back, and the leg bending support 300 supports the patient's legs. Both the back support 200 and the leg bending support 300 are pivotally connected to the frame 100 and located on the same side of the frame 100. The rotation axis of the back support 200 is parallel to the rotation axis of the leg bending support 300.

[0064] Specifically, the frame 100 includes an outer frame 110 and a hip support 120. The two opposite ends of the hip support 120 are connected to the two opposite inner walls of the outer frame 110, and the other two opposite ends of the hip support 120 are pivotally connected to the back support 200 and the leg flexion 300. This arrangement facilitates support for the patient's hips. In other embodiments, the back support 200 and the leg flexion 300 may both be pivotally connected to the outer frame 110. Furthermore, when the back support 200 and the leg flexion 300 are located on the same side of the frame 100, the corresponding position of the frame 100 can limit the back support 200 and the leg flexion 300, preventing them from rotating downwards under their own weight, thus ensuring that the back support 200 and the leg flexion 300 can effectively support the patient's back and legs. Furthermore, the forming methods of the back support 200, the bent leg support 300, the outer frame 110, and the hip support 120 are all set with reference to the forming method of the frame 100 mentioned above, and will not be described in detail here.

[0065] In addition, a calf support (not shown) can be pivotally connected to the side of the leg bending component 300 facing away from the back support component 200. With this configuration, the patient's thigh and calf can be bent synchronously under the combined action of the leg bending component 300 and the calf support.

[0066] The drive device 400 can reciprocate along the line connecting the back support 200 and the leg bending member 300, so that the drive device 400 can selectively abut against either the back support 200 or the leg bending member 300 to rotate relative to the frame 100, assisting the patient in raising their back or bending their legs.

[0067] It should be noted that the drive device 400 may be partially capable of reciprocating along the line connecting the backrest 200 and the leg bend 300, or the drive device 400 may be entirely capable of moving along the line connecting the backrest 200 and the leg bend 300; no specific limitation is made here.

[0068] Specifically, the drive unit 400 is mounted on the frame 100. This configuration enables a high degree of integration between the frame 100, the backrest assembly 200, the leg arch assembly 300, and the drive unit 400, making the medical care bed structure 1000 easy to use. Alternatively, the drive unit 400 can be a separate unit, not mounted on the frame 100, and can selectively rotate upwards against either the backrest assembly 200 or the leg arch assembly 300.

[0069] It is understandable that the back-raising component 200 and the leg-bending component 300 can both be set to one or more. When both the back-raising component 200 and the leg-bending component 300 are set to multiple, the back-raising component 200 and the leg-bending component 300 are set to correspond one-to-one. The multiple back-raising components 200 and the multiple leg-bending components 300 are arranged horizontally side by side. The drive device 400 can selectively push against the multiple horizontally arranged back-raising components 200 to rotate upward to assist the patient in raising their back, or push against the multiple horizontally arranged leg-bending components 300 to rotate upward to assist the patient in bending their legs.

[0070] Obviously, the drive unit 400 can be a manually operated drive structure or a drive structure with its own power source. When the drive unit 400 is a drive structure with its own power source, the medical care bed structure 1000 may also be equipped with a controller (not shown) electrically connected to the drive unit 400. The controller is used to control the movement of the drive unit 400 from the backrest 200 to the leg flexor 300 or from the leg flexor 300 to the backrest 200. The controller may be a separate device or it may be part of the drive unit 400.

[0071] Through the above technical solution, when assisting a patient to sit up, the driving device 400 selects and abuts the back-lifting component 200 to rotate upward relative to the frame 100, thus assisting the patient to sit up. After the patient finishes sitting up, the driving device 400 gradually releases its abutment on the back-lifting component 200. Under its own weight and the action of the patient's back, the back-lifting component 200 rotates downward relative to the frame 100 and remains in contact with the driving device 400 until it rotates to a horizontal position. Similarly, when assisting a patient to bend their legs, the driving device 400 selects and abuts the leg-bending component 300 to rotate upward relative to the frame 100, thus assisting the patient to bend their legs. After the patient finishes bending their legs, the driving device 400 gradually releases its abutment on the leg-bending component 300. Under its own weight and the action of the patient's legs, the leg-bending component 300 rotates downward relative to the frame 100 and remains in contact with the driving device 400 until it rotates to a horizontal position. This configuration allows for both backrest raising and leg bending functions to be achieved through a single drive unit 400, thereby effectively reducing production costs. Furthermore, it simplifies the structure 1000 of the medical care bed.

[0072] Please see Figure 1 and Figure 2 There are many types of driving devices 400. In one embodiment of the present invention, the driving device 400 includes a driving member 410 and a supporting member 420.

[0073] The drive member 410 is mounted on the frame 100 and is connected to the abutment member 420. The abutment member 420 extends from the curved leg member 300 to the backrest member 200 and is at least partially confined between the backrest member 200 and the curved leg member 300. The drive member 410 is used to drive the abutment member 420 to reciprocate along the line connecting the backrest member 200 and the curved leg member 300 so that the abutment member 420 can selectively abut against either the backrest member 200 or the curved leg member 300 to rotate relative to the frame 100.

[0074] The function of the aforementioned abutment 420, which is at least partially confined between the backrest member 200 and the leg-bending member 300, is to restrict the positional relationship between the abutment 420 and the backrest member 200 and the leg-bending member 300, so that the abutment 420 is at least partially located between the backrest member 200 and the leg-bending member 300. This allows the abutment 420 to selectively abut against either the backrest member 200 or the leg-bending member 300 relative to the frame 100 and rotate upwards. Clearly, regardless of whether the abutment 420 abuts against the backrest member 200 or the leg-bending member 300, from an overall perspective, the abutment 420 is always at least partially located between the backrest member 200 and the leg-bending member 300.

[0075] The aforementioned driving device 400 essentially works as follows: when the abutment member 420 abuts against the backrest member 200 and rotates upward, a rotatable contact point is formed between the abutment member 420 and the backrest member 200, thereby driving the backrest member 200 to rotate upward. The principle is the same as when the abutment member 420 abuts against the curved leg member 300 and rotates upward.

[0076] In this embodiment, please refer to Figure 1 The description focuses on the fact that the abutment 420 is partially confined between the backrest 200 and the leg bend 300. In other embodiments, the abutment 420 may also be entirely confined between the backrest 200 and the leg bend 300.

[0077] Through the above technical solution, when assisting the patient to raise their back, the driving component 410 drives the supporting component 420 to translate from the leg-bending component 300 to the back-raising component 200. The supporting component 420 abuts against the back-raising component 200 and rotates upward relative to the frame 100, assisting the patient to raise their back. After the patient finishes raising their back, the driving component 410 drives the supporting component 420 to translate from the back-raising component 200 to the leg-bending component 300. Under the combined action of its own weight and the patient's back, the back-raising component 200 rotates downward relative to the frame 100 and remains in contact with the supporting component 420 until the back-raising component 200 rotates to a horizontal position. Similarly, when assisting the patient to bend their legs, the drive unit 410 drives the abutment unit 420 to translate from the back-raising unit 200 to the leg-bending unit 300. The abutment unit 420 abuts the leg-bending unit 300 and rotates upward relative to the frame 100 to assist the patient to bend their legs. After the patient finishes bending their legs, the drive unit 410 drives the abutment unit 420 to translate from the leg-bending unit 300 to the back-raising unit 200. Under the combined action of its own weight and the patient's back, the leg-bending unit 300 rotates downward relative to the frame 100 and remains in contact with the abutment unit 420 until the leg-bending unit 300 rotates to a horizontal position.

[0078] In other embodiments, the reciprocating motion of the drive device 400 along the line connecting the backrest member 200 and the leg-bending member 300 can also be a swing motion. The drive device 400 includes a rotating member (not shown) and a swing arm (not shown). The rotating member is kinetically connected to the swing arm and drives the swing arm to swing back and forth along the line connecting the backrest member 200 and the leg-bending member 300, so that the swing arm can selectively abut against either the backrest member 200 or the leg-bending member 300 and rotate upward relative to the frame 100, assisting the patient in raising their back or bending their legs. The drive device 400 may also include a moving trolley (not shown) and a telescopic rod (not shown) mounted on the moving trolley. When the moving trolley moves below the backrest member 200 or the leg-bending member 300, the telescopic rod extends, allowing it to abut against the backrest member 200 or the leg-bending member 300 and rotate upward relative to the frame 100.

[0079] Further, please refer to Figure 1 and Figure 2 The drive device 400 also includes a rotating seat 430, which is pivotally connected to the frame 100. The rotation axis of the rotating seat 430 is parallel to the rotation axis of the lifting member 200. The end of the drive member 410 away from the abutment member 420 is located on the rotating seat 430. With this configuration, when the drive member 410 drives the abutment member 420 to abut the lifting member 200 or the curved leg member 300 to rotate, the abutment member 420 and the lifting member 200 or the curved leg member 300 form a rotatable and movable abutment point. Combined with the setting of the rotating seat 430, the drive member 410 and the abutment member 420 rotate together with the lifting member 200, thereby forming a crank-connecting rod structure in the drive device 400, which is beneficial for applying abutment force to the lifting member 200 or the curved leg member 300.

[0080] Please see Figure 1 and Figure 2 In order to facilitate the confinement of at least a portion of the abutment 420 between the backrest member 200 and the leg bending member 300, in one embodiment of the present invention, the backrest member 200 and the leg bending member 300 are respectively provided with a backrest force-bearing member 210 and a leg bending force-bearing member 310, and the abutment 420 is at least partially confined between the backrest force-bearing member 210 and the leg bending force-bearing member 310, so that the abutment 420 can selectively abut against either the backrest force-bearing member 210 or the leg bending force-bearing member 310 to rotate relative to the frame 100.

[0081] Specifically, one end of the backrest force-bearing member 210 is connected to the backrest member 200, and the other end of the backrest force-bearing member 210 is inclined downward toward the leg bending member 300. One end of the leg bending force-bearing member 310 is connected to the leg bending member 300, and the other end of the leg bending force-bearing member 310 is inclined downward toward the backrest member 200. This arrangement facilitates the application of force by the abutment member 420 to the backrest force-bearing member 210 or the leg bending force-bearing member 310.

[0082] Please see Figure 1 and Figure 2 There are many ways in which the aforementioned abutment 420 is at least partially confined between the backrest force-bearing member 210 and the leg-bending force-bearing member 310. In one embodiment of the present invention, such as... Figure 2-4 As shown, the abutment member 420 is provided with a curved leg groove 420a extending along its translational direction, and the curved leg force-bearing member 310 is provided with a curved leg rod 320 that can be rotatably and slidably engaged with the curved leg groove 420a, so that the curved leg rod 320 can form a rotatable abutment point with the groove wall of the curved leg groove 420a away from the drive member 430. At the same time, the abutment member 420 can abut against the lifting force-bearing member 210 and rotate relative to the frame 100 when moving from the curved leg member 300 to the lifting member 200.

[0083] Specifically, the lifting force-bearing member 210 is located on the movement trajectory of the end of the abutment member 420 away from the drive member 410 in the direction from the bent leg member 300 to the lifting member 200, so that the end of the abutment member 420 away from the drive member 410 can abut against the lifting force-bearing member 210 and rotate upward relative to the frame 100 when moving in the direction from the bent leg member 300 to the lifting member 200. In other embodiments, the abutment member 420 may also have a structural member on its side for abutting against the lifting force-bearing member 210.

[0084] It is understandable that when the supporting member 420 and the lifting force member 210 are unable to make contact, the groove wall of the curved leg groove 420a near the driving member 410 is spaced apart from the curved leg rod 320. The larger the distance between the groove wall of the curved leg groove 420a near the driving member 410 and the curved leg rod 320, the greater the stroke of the supporting member 420 when it moves from the curved leg member 300 to the lifting member 200, and the greater the angle at which the lifting member 200 can be rotated upward relative to the frame 100 by the lifting force member 210. Similarly, when the supporting member 420 and the lifting force member 210 are unable to make contact, the smaller the distance between the groove wall of the curved leg groove 420a away from the driving member 410 and the curved leg rod 320, the shorter the time it takes for the supporting member 420 to move from the lifting member 200 to the curved leg member 300 until the groove wall of the curved leg groove 420a away from the driving member 410 makes contact with the curved leg rod 320. This makes it easier for the supporting member 420 to switch from supporting the lifting force member 210 to supporting the curved leg force member 310.

[0085] In one specific embodiment, please refer to Figure 1 and Figure 2 When the abutment 420 is in its initial position, the end of the abutment 420 away from the drive member 410 has no contact with the backrest force member 210, and the groove wall of the curved leg groove 420a away from the drive member 410 has no contact with the curved leg rod 320. This arrangement allows the abutment 420 to quickly respond to selectively abut against either the backrest force member 210 or the curved leg force member 310.

[0086] With the above technical solution, when assisting the patient to raise their back, the driving member 410 drives the supporting member 420 to move from the bent leg member 300 to the raising member 200. The bent leg member 320 is fixed because it can slide along the bent leg groove 420a. The end of the supporting member 420 away from the driving member 410 abuts against the raising force member 210 and applies a supporting force to the raising force member 210, so as to drive the raising member 200 to rotate upward relative to the frame 100, thereby assisting the patient to raise their back. When assisting the patient to bend their legs, the drive member 410 drives the abutment member 420 to move from the back-raising member 200 to the leg-bending member 300. The back-raising force-bearing member 210 is fixed because it is out of contact with the abutment member 420. The leg-bending rod 320 slides along the leg-bending groove 420a. The groove wall of the leg-bending groove 420a away from the drive member 410 abuts against the leg-bending rod 320, applying a resisting force to the leg-bending force-bearing member 310, so as to drive the leg-bending member 300 to rotate upward relative to the frame 100, thereby assisting the patient to bend their legs.

[0087] In other embodiments, when the abutment 420 is in the initial state, at least a portion of the abutment 420 can be directly clamped by the backrest force member 210 and the leg bending force member 310, so that at least a portion of the abutment 420 is confined between the backrest force member 210 and the leg bending force member 310.

[0088] Please see Figure 1 , Figure 3 as well as Figure 4 In one specific embodiment of the present invention, the leg-bending force-bearing member 310 is pivotally connected to the leg-bending member 300 and its rotation angle in the direction away from the backrest member 200 is limited. The end of the abutment member 420 away from the drive member 410 forms a backrest force-applying end. One of the backrest force-applying end and the backrest force-bearing member 210 is provided with a backrest rod 220, and the other of the backrest force-bearing end and the backrest force-bearing member 210 is provided with a backrest opening 420b for cooperating with the backrest rod 220. Figure 4 The diagram shows a backrest opening 420b at the backrest force application end. Specifically, the backrest opening 420b is open on the side near the frame 100, and the backrest force-bearing member 210 is provided with a backrest rod 220. The backrest rod 220 can cooperate with the backrest opening 420b when the abutment member 420 moves in the direction from the bent leg member 300 to the backrest member 200.

[0089] When a resisting force is applied to the lifting member 210 through the cooperation of the lifting opening 420b and the lifting rod 220, the lifting member 210 rotates away from the curved leg member 300, and the curved leg member 310 rotates accordingly. The curved leg rod 320 slides within the curved leg groove 420a, without interfering with the application of the resisting force to the lifting member 210 through the cooperation of the lifting opening 420b and the lifting rod 220. Furthermore, the sliding of the curved leg rod 320 within the curved leg groove 420a restricts the trajectory of the resisting member 420, ensuring that the contact position between the resisting member 420 and the lifting member 210 remains unchanged, thereby enabling a stable application of the resisting force to the lifting member 210.

[0090] In addition, after the bent leg rod 320 reaches the limit rotation position, when the bent leg rod 320 and the bent leg groove 420a cooperate to apply a resisting force to the bent leg force-bearing member 310, the relative position of the bent leg force-bearing member 310 and the bent leg member 300 is fixed, so that the bent leg force-bearing member 310 can apply a resisting force to the bent leg member 300.

[0091] It is understandable that the supporting member 420 may have a backing groove, and the backing force-bearing member 210 may have a rod structure. Please refer to [link / reference]. Figure 5 The abutment member 420 is provided with a back-raising groove 420c extending along its translational direction, and the back-raising force member 210 is provided with a back-raising rod 220 that can be rotatably and slidably engaged with the back-raising groove 420c. When the abutment member 420 moves from the back-raising member 200 to the bent leg member 300, it abuts the bent leg force member 310 and rotates upward relative to the frame 100.

[0092] Alternatively, the supporting member 420 may have two groove structures, and both the backrest force-bearing member 210 and the curved leg force-bearing member 310 may have rod structures. Please refer to [link / reference]. Figure 6The abutting member 420 is provided with a curved leg groove 420a and a back-raising groove 420c that both extend along its translational direction. The curved leg force-bearing member 310 is pivotally connected to the curved leg member 300 and its rotation angle in the direction away from the back-raising member 200 is restricted. The curved leg force-bearing member 310 is provided with a curved leg rod 320 that can be rotatably and slidably engaged with the curved leg groove 420a. The back-raising force-bearing member 210 is pivotally connected to the back-raising member 200 and its rotation angle in the direction away from the curved leg member 300 is restricted. The back-raising force-bearing member 210 is provided with a back-raising rod 220 that can be rotatably and slidably engaged with the back-raising groove 420c. When one of the curved leg rod 300 and the back-raising rod 200 is abutted, the other of the curved leg rod 300 and the back-raising rod 200 can slide.

[0093] When the abutment 420 is provided with a curved leg groove 420a, a backrest groove 420c, a curved leg rod 320, and a backrest rod 220, there are three cases:

[0094] For the first option, please refer to [the original text]. Figure 6 The leg-bending groove 420a and the back-raising groove 420c are spaced apart from the leg-bending member 300 to the back-raising member 200. The leg-bending rod 320 has no contact with the groove wall of the leg-bending groove 420a away from the drive member 410, and the back-raising rod 220 has no contact with the groove wall of the back-raising groove 420c close to the drive member 410.

[0095] The second option, please refer to Figure 7 The leg-bending groove 420a and the back-raising groove 420c are spaced apart from the back-raising member 200 to the leg-bending member 300. The back-raising rod 220 is located near the back-raising groove 420c and close to the groove wall of the drive member 410. The leg-bending rod 320 is located near the leg-bending groove 420a and away from the groove wall of the drive member 410. The leg-bending force member 310 and the back-raising force member 210 are spaced apart along the rotation axis of the back-raising force member 210.

[0096] The third type, please refer to Figure 8 The leg-bending groove 420a and the back-raising groove 420c are arranged in parallel. The back-raising rod 220 and the leg-bending rod 320 are spaced apart from the leg-bending member 300 to the back-raising member 200. The leg-bending force-bearing member 310 and the back-raising force-bearing member 210 are spaced apart along the rotation axis of the back-raising force-bearing member 210.

[0097] Alternatively, the supporting member 420 may have a groove structure, and both the back-supporting member 210 and the curved leg-supporting member 310 may have rod structures. Please refer to [link / reference]. Figure 9The abutment member 420 is provided with a curved leg lifting groove 420d extending along its translational direction. The curved leg force-bearing member 310 is pivotally connected to the curved leg member 300 and its rotation angle in the direction away from the lifting member 200 is restricted. The curved leg force-bearing member 310 is provided with a curved leg rod 320 that can be rotatably and slidably engaged with the curved leg lifting groove 420d. The lifting back force-bearing member 210 is pivotally connected to the lifting member 200 and its rotation angle in the direction away from the curved leg member 300 is restricted. The lifting back force-bearing member 210 is provided with a lifting back rod 220 that can be rotatably and slidably engaged with the curved leg lifting groove 420d. The curved leg rod 320 and the lifting back rod 220 are spaced apart from the lifting member 200 to the curved leg member 300. The curved leg force-bearing member 310 and the lifting back force-bearing member 210 are spaced apart along the rotation axis of the lifting back force-bearing member 210 to avoid interference between the curved leg force-bearing member 310 and the lifting back force-bearing member 210.

[0098] It is understandable that the aforementioned combination of the curved leg bar 320 with the curved leg groove 420a, and the backrest opening 420b and backrest bar 220, can be replaced with a curved leg bar 320 and a curved leg opening 420e. Please refer to [link / reference]. Figures 10 to 13 Therefore, in one embodiment of the present invention, the end of the abutment member 420 away from the drive member 410 forms a back-lifting force-applying end, one of the back-lifting force-applying end and the back-lifting force-receiving member 210 is provided with a back-lifting opening 420b, and the other of the back-lifting force-applying end and the back-lifting force-receiving member 210 is provided with a back-lifting rod 220 for cooperating with the back-lifting opening 420b. Figure 11 The diagram shows a case where the backrest application end has a backrest opening 420b, and the backrest receiving member 210 has a backrest rod 220; one of the abutment member 420 and the curved leg receiving member 310 has a curved leg opening 420e, and the other of the abutment member 420 and the curved leg receiving member 310 has a curved leg rod 320 for engaging with the curved leg opening 420e. Figure 11 The diagram shows a case where the abutment member 420 has a curved leg opening 420e and the curved leg force-bearing member 310 has a curved leg rod 320.

[0099] When the backrest lever 220 engages with the backrest opening 420b, the leg bend lever 320 is released from its constraint with the leg bend opening 420e; conversely, when the backrest lever 220 is released from its constraint with the backrest opening 420b, the leg bend lever 320 can engage with the leg bend opening 420e.

[0100] It should be noted that the aforementioned engagement of the back support rod 220 with the back support opening 420b refers to the position where the back support rod 220 abuts against the inner wall of the back support opening 420b facing its open end. The aforementioned release of constraint between the back support rod 220 and the back support opening 420b refers to the back support rod 220 and the inner wall of the back support opening 420b being spaced apart at any position. This avoids interference with the curved leg rod 320, which, by abutting against the inner wall of the curved leg opening 420e facing its open end, drives the curved leg force-applying component 600 and the curved leg component 300 to rotate upwards relative to the frame 100. The release of constraint between the back support rod 220 and the back support opening 420b can be achieved by the back support rod 220 being located outside the back support opening 420b; or by the back support rod 220 having an outer diameter smaller than the width of the back support opening 420b and being located inside the back support opening 420b. The cooperation between the curved leg bar 320 and the curved leg opening 420e, as well as the method of releasing the constraint, are the same as the cooperation between the backrest bar 220 and the backrest opening 420b, and will not be described in detail here.

[0101] With the above technical solution, when it is necessary to drive the lifting member 200 to rotate upward relative to the frame 100, the lifting rod 220 engages with the lifting opening 420b, the curved leg rod 320 is released from constraint with the curved leg opening 420e, and the driving member 410 drives the abutment member 420 to move away from the driving member 410, thus driving the lifting member 200 to rotate upward relative to the frame 100. Similarly, when it is necessary to drive the curved leg member 300 to rotate upward relative to the frame 100, the driving member 410 drives the abutment member 420 to move closer to the driving member 410, the curved leg rod 320 engages with the curved leg opening 420e, the lifting rod 220 is released from constraint with the lifting opening 420b, and the driving member 410 continues to drive the abutment member 420 to move closer to the rotating seat 430, thus driving the curved leg member 300 to rotate upward relative to the frame 100. In addition, during the upward rotation of the drive lifting member 200 relative to the frame 100, the bent leg rod 320 and the bent leg opening 420e are released from constraint, which can also prevent the bent leg rod 320 from contacting the abutment member 420, the bent leg force-bearing member 310, the bent leg rod 320, etc., thus preventing noise and improving the user experience.

[0102] Please see Figures 14 to 17 Furthermore, in one embodiment of the present invention, both the back opening 420b and the leg opening 420e include a guide section 420f and a stop section 420g. The diameter of the guide section 420f gradually decreases from the guide section 420f to the stop section 420g. The side of each guide section 420f away from the corresponding stop section 420g is open. The back lever 220 and the leg lever 320 are both used to cooperate with the corresponding stop section 420g.

[0103] The constraint between the aforementioned backrest lever 220 and the backrest opening 420b can be released if the backrest lever 220 is located within the guide section 420f of the backrest opening 420b. Similarly, the constraint between the aforementioned leg bend lever 320 and the leg bend opening 420e can be released if the leg bend lever 320 is located within the guide section 420f of the leg bend opening 420e.

[0104] Specifically, one of the flexing leg lever 320 and the backrest lever 220 is located within the corresponding abutment section 420g, while the other is located within the corresponding guide section 420f. This arrangement ensures that when one of the backrest lever 220 and the flexing leg lever 320 engages with the corresponding abutment section 420g for abutment, the other will not interfere with the other. Figure 16 The diagram shows the backrest bar 220 located within the corresponding guide section 420f, and the flexor bar 320 located within the corresponding abutment section 420g.

[0105] Through the above technical solution, by limiting the guide section 420f and the abutment section 420g, when the lifting rod 220 and the lifting opening 420b are self-fitted and released from constraint, the curved leg rod 320 is easily guided by the guide section 420f of the curved leg opening 420e to enter the abutment section 420g of the curved leg opening 420e. Similarly, when the curved leg rod 320 and the curved leg opening 420e are self-fitted and released from constraint, the lifting rod 220 is easily guided by the guide section 420f of the lifting opening 420b to enter the abutment section 420g of the lifting opening 420b. Furthermore, it can effectively prevent the abutment member 420 from rotating due to the pivot connection between the rotating seat 430 and the frame 100.

[0106] Please see Figure 12 and Figure 13 To facilitate the setting of the curved leg opening 420e, in one embodiment of the present invention, the driving device 400 further includes a U-shaped curved leg applying member 600. The inner wall of the curved leg applying member 600 facing its open end is fitted onto the abutment member 420. The open end of the curved leg applying member 600 extends beyond the abutment member 420 and is provided with a curved leg opening 420e on the side opposite to the curved leg member 300. The curved leg receiving member 310 is provided with a curved leg rod 320. With this configuration, the curved leg opening 420e is set by means of the curved leg applying member 600, making it convenient to set the curved leg opening 420e on the abutment member 420.

[0107] Please see Figure 12 and Figure 13 To achieve the following: the lifting support member 210 is pivotally connected to the lifting support member 200 and can only rotate in the direction close to the leg bend member 300, and the leg bend member 310 is pivotally connected to the leg bend member 300 and can only rotate in the direction close to the lifting support member 200, in one embodiment of the present invention, the lifting support member 210 is pivotally connected to the lifting support member 200, and the leg bend member 310 is pivotally connected to the leg bend member 300.

[0108] The medical care bed structure also includes two limiting members 500. One limiting member 500 is located on the backrest support 200 and abuts against the backrest force-bearing member 210 to limit the rotation angle of the backrest force-bearing member 210 away from the leg bending member 300. The other limiting member 500 is located on the leg bending member 300 and abuts against the leg bending force-bearing member 310 to limit the rotation angle of the leg bending force-bearing member 310 away from the backrest support 200. With this configuration, by limiting the rotation direction of the backrest support 200 and the leg bending member 300 with the two limiting members 500, it is possible to ensure that the backrest force-bearing member 210 can only rotate in the direction closer to the leg bending member 300, and the leg bending force-bearing member 310 can only rotate in the direction closer to the backrest force-bearing member 210.

[0109] Specifically, please refer to Figure 12 and Figure 13 Both the backrest member 200 and the leg-bending member 300 are provided with mounting rods 231 extending along the rotation axis of the backrest member 200. Both the backrest force-bearing member 210 and the leg-bending force-bearing member 310 include two parallel force-bearing sections 232 and a connecting section 233 connecting the two force-bearing sections 232. Each force-bearing section 232 is provided with a through hole (not shown). The two through holes of the two force-bearing sections 232 corresponding to the backrest force-bearing member 210 cooperate with one mounting rod 231, and the two through holes of the two force-bearing sections 232 corresponding to the leg-bearing member 310 cooperate with another mounting rod 231. The two force-bearing sections 232 corresponding to the backrest force-bearing member 210 are inclined from the backrest member 200 towards the leg-bearing member 300, and the two force-bearing sections 232 corresponding to the leg-bearing member 310 are inclined from the leg-bearing member 300 towards the backrest member 200.

[0110] Please see Figure 12 and Figure 13 Each limiting member 500 includes two parallel locking sections 510 and a limiting section 520 connecting the two locking sections 510. Each locking section 510 is arc-shaped. The two locking sections 510 of each limiting member 500 are locked to the corresponding mounting rod 231 and clamp the corresponding two connecting sections 233. One limiting section 520 abuts against the upper end of the connecting section 233 of the backrest force-bearing member 210 to limit the rotation angle of the backrest force-bearing member 210 away from the leg bending member 300. The other limiting section 520 abuts against the upper end of the connecting section 233 of the leg bending force-bearing member 310 to limit the rotation angle of the leg bending force-bearing member 310 away from the backrest force-bearing member 200.

[0111] See Figures 1 to 17There are many types of driving member 410 and abutting member 420. In one embodiment of the present invention, driving member 410 and abutting member 420 are respectively configured as a screw and a sleeve. The screw extends from the curved leg member 300 to the backing member 200. One end of the screw is pivotally connected to the rotating seat 430, and the other end of the screw is threadedly connected to the sleeve. With this configuration, rotating the screw can drive the sleeve to translate in a direction closer to or away from the rotating seat 430.

[0112] Specifically, the end of the screw away from the sleeve is pivotally connected to the rotating seat 430 and a rocker arm 440 is connected through the rotating seat 430. With this configuration, the screw can be rotated by rotating the rocker arm 440, making the rotation of the screw convenient.

[0113] It should be noted that when the abutment 420 is configured as a sleeve, and the abutment 420 is provided with a curved leg groove 420a, and the curved leg force-bearing end is provided with a curved leg abutment 420, the sleeve can be limited, allowing the sleeve to move only axially. When the abutment 420 is configured as a sleeve, and one of the lifting rod 220 and the curved leg rod 320 engages with the corresponding abutment section 420g, and the other of the lifting rod 220 and the curved leg rod 320 is located within the corresponding guide section 420f, the sleeve can also be limited, allowing the sleeve to move only axially. Furthermore, the design of the guide section 420f effectively prevents the sleeve from rotating during axial translation along the screw.

[0114] In other embodiments, the drive component 410 may also be configured as a lead screw linear transmission module, a cylinder linear transmission module or other linear transmission structures, and the abutment component 420 may also be configured as a structural component with a certain length.

[0115] Please see Figure 3 and Figure 4 To facilitate the installation of the curved leg rod 320, in one embodiment of the present invention, the curved leg groove 420a is provided through both ends on the rotation axis of the curved leg member 300. The two force-bearing segments 232 corresponding to the curved leg force-bearing member 310 are respectively provided on both sides of the abutment member 420 on the rotation axis of the curved leg member 300 and are spaced apart from the abutment member 420. The two force-bearing segments 232 corresponding to the curved leg force-bearing member 310 are provided with through holes 232a. The curved leg rod 320 is set as a bolt. The bolt passes through the through hole 232a of one force-bearing segment 232 of the curved leg force-bearing member 310, the curved leg groove 420a, and the through hole 232a of the other force-bearing segment 232 of the curved leg force-bearing member 310 in sequence, and then is threaded with a nut 321. The head of the bolt and the nut 321 abut against the side of the two force-bearing segments 232 of the curved leg force-bearing member 310 that are far apart from each other.

[0116] Further, please refer to Figure 16 and Figure 17In another embodiment of the present invention, a guide sleeve 322 may be provided between the head of the bolt and the corresponding force-bearing segment 232 to prevent the bolt head and the force-bearing end from colliding after the abutment member 420 swings. Similarly, a guide sleeve 322 may also be provided between the nut 321 and the corresponding force-bearing segment 232. In addition, the curved leg rod 320 may also be configured as a headless rivet. Furthermore, the curved leg rod 320 being configured as a bolt allows the curved leg rod 320 to slide along the limiting groove and rotate relative to the abutment member 420, ensuring that it can abut the curved leg member 300 through the curved leg force-bearing member 310.

[0117] In addition, the backrest bar 220 is set with reference to the bent leg bar 320 mentioned above, and will not be described in detail here.

[0118] See Figure 1 The present invention also proposes a medical care bed (not shown), which includes the medical care bed structure 1000 as described above.

[0119] By way of example and not limitation, the medical care bed may also include bed legs (not shown) that are mounted on and support the frame 100, and the medical care bed may also include a bed frame (not shown) for the frame 100 to be placed on.

[0120] The specific structure of the medical care bed structure 1000 is as described in the above embodiments. Since the medical care bed adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0121] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0122] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
