Referring to fig. 1, fig. 1 is a schematic diagram of a conventional medical bed 100. The conventional medical bed 100 includes a rotatable bed board 110 rotatable on a bed frame and a fixed bed board 120 fixed on the bed frame, and a mattress 130 is laid on the medical bed, and when the rotatable bed board is rotated as shown in the figure, the part shown by the dotted line in fig. 1 is clearly interfered with the mattress on the fixed bed board 120, thereby causing wrinkles, arching, etc. of the mattress. In view of the above, the present application provides a sitting and lying structure and a medical bed to solve such technical problems. In particular, reference is made to the embodiments and figures provided by the present application.

Referring to fig. 2, fig. 2 is a schematic diagram of a first structure of a sitting and lying structure 200 according to an embodiment of the application. The sitting and lying structure 200 provided by the application comprises: a first rotation receiving module 210 and a stationary receiving module 220. First rotating uptake module 210 is configured to lay a first shim 310 on its surface, and stationary uptake module 220 is configured to lay a second shim 320 on its surface; first shim 310 has a first shim end 311 adjacent second shim 320, second shim 320 has a second shim end 321 adjacent first shim 310, and mount receiving module 220 has a mount receiving end 221 adjacent first rotation receiving module 210; the first rotation receiving module 210 is rotatably connected with the fixed receiving module 220 through a first rotation shaft 212, and the first rotation shaft 212 is parallel to a plane of the first rotation receiving module 210 and a plane of the fixed receiving module 220; the smallest of the distance from the first rotation shaft 212 to the fixed receiving end 221 and the distance from the first rotation shaft 212 to the second pad end 321 is greater than the distance from the first rotation shaft 212 to the tip 312; wherein top end 312 includes an interface between an upper surface of first shim 310 and first shim end 311.

The sitting and lying structure 200 may be a structure such as a home bed, a sofa, a car seat, or a medical bed 20. The sitting and lying structure 200 may have an adjusting function, namely the first rotation receiving module 210. The first rotation receiving module 210 may be a bed plate, a sofa, a backrest of a seat, etc. that can be adjusted by rotation. The fixing and receiving module 220 may be the rest of the sitting and lying structure 200 except the first rotation receiving module 210, for example, the medical bed 20, and the fixing and receiving module 220 may be a frame of the medical bed 20 and a bed plate which cannot rotate on the frame.

The first cushion 310 may be a mattress, a sofa cushion, a cushion, or the like. Similarly, second cushion 320 may be a mattress, sofa cushion, seat cushion, or the like. First shim 310 and second shim 320 may be joined together or may even be two portions of a single piece shim. There may not be any connection between first shim 310 and second shim 320. The shape and size of first cushion 310 and second cushion 320 are adapted to the sitting and lying structure 200 for the purpose of laying them on the sitting and lying structure 200 to improve the comfort when sitting and lying.

It should be noted that, in the case where the first cushion layer 310 is laid on the first rotation receiving module 210 and the second cushion layer 320 is laid on the fixed receiving module 220, the first cushion layer 310 rotates together with the first rotation receiving module 210 during rotation. Thus, the first shim 310 is relatively stationary with the first rotation receiving module 210. Of course, during the rotation of the first rotation receiving module 210, the position of the first rotation shaft 212 relative to the first rotation receiving module 210 and the first cushion layer 310 is not changed, so the distance between the first rotation shaft 212 and the upper surface of the first cushion layer 310 is generally fixed.

The anchor receiving end 221, projected on the plane of the second shim 320 at anchor receiving end 221, may be located outside of the second shim 320, may be located within the second shim 320, or may even coincide with the second shim end 321.

As can be seen from fig. 2, the main reason for the wrinkling or arching of the cushion layer is: first aspect: when the first rotation receiving module 210 rotates by a certain angle (i.e. the included angle between the upper surface of the first cushion layer 310 and the upper surface of the second cushion layer 320 is smaller than 180 °), the upper surface of the first cushion layer 310 or the first cushion layer end 311 will squeeze the second cushion layer end 321 of the second cushion layer 320, thereby causing wrinkles or arching of the second cushion layer 320; in the second aspect, when the first rotation receiving module 210 rotates a certain angle, the swing of the first cushion end 311 is blocked by the second cushion end 321 or the end of the fixed receiving module 220, so as to cause the first cushion 310 to buckle or arch.

Therefore, the first rotating shaft 212 is moved by a certain distance in the left direction in fig. 3, so that the first cushion layer 310 rotates to an arbitrary angle together with the rotation receiving end 211, and both the second cushion layer end 321 and the end of the fixed receiving module 220 can be avoided, and accordingly, wrinkling or arching of the first cushion layer 310 and the second cushion layer 320 caused by the rotation of the first rotation receiving module 210 can be avoided to a certain extent.

On this basis, as long as the smallest one of the distance from the first rotation shaft 212 to the fixed receiving end 221 and the distance from the first rotation shaft 212 to the second pad layer end 321 is larger than the distance from the first rotation shaft 212 to the tip 312. It is possible to make more room for the first pad end 311 to swing with during the rotation of the first rotation receiving module 210. Accordingly, the first shim 310 does not contact the second shim end 321 or the end of the anchor handling module 220 during rotation therewith. In consideration of the dimensions of the first rotation shaft 212, the fixed receiving end 221, and the second cushion end 321 itself, the distance from the first rotation shaft 212 to the fixed receiving end 221 may be the shortest distance between the first rotation shaft 212 and the fixed receiving end 221, and the distance from the first rotation shaft 212 to the second cushion end 321 may be the shortest distance therebetween.

In the above implementation process, by setting the first rotation shaft 212 at a position away from the fixed receiving module 220 by a certain distance, the problem that the first cushion layer 310 is interfered by the fixed receiving module 220 or the second cushion layer 320 during the rotation of the first cushion layer 310 along with the first rotation receiving module 210 is avoided to a certain extent. Further, the cushion folds arch caused by the first rotation receiving module 210 rotating a certain angle in the sitting and lying structure 200 are reduced.

Referring to fig. 3, fig. 3 is a schematic diagram of a second structure of a sitting and lying structure 200 according to an embodiment of the application. In some alternative embodiments, the first rotation receiving module 210 has a rotation receiving end 211. The projection of rotation receiving end 211 onto the plane of first shim 310 coincides with first shim end 311.

Since the first shim 310 is relatively stationary with the first spin-bearing module 210. On the basis, the projection of the rotation receiving end 211 on the plane of the first cushion layer 310 coincides with the first cushion layer end 311, and it is understood that the rotation receiving end 211 is flush with the first cushion layer end 311 in the vertical direction in fig. 4. As such, the first rotation receiving module 210 may provide more substantial support for the first cushion 310.

In the above implementation process, when the projection of the rotation receiving end 211 on the plane where the first cushion layer 310 is located is overlapped with the first cushion layer end 311, that is, when the first cushion layer 310 is in a horizontal state, the rotation receiving end 211 is aligned with the first cushion layer end 311 in a vertical direction, so that the first cushion layer end 311 can also be received by the first rotation receiving module 210 and supported by the first rotation receiving module 210. Further, the comfort of the sitting and lying structure 200 is increased with the first cushion layer 310 being more fully supported.

Referring to fig. 4, fig. 4 is a schematic diagram of a third structure of a sitting and lying structure 200 according to an embodiment of the application. In some alternative embodiments, anchor receiving end 221 has an anchor receiving end 221 projection on the plane of second shim 320, and anchor receiving end 221 projections on top of second shim 320.

That is, second shim end 321 of second shim 320 is closer to first shim 310 than is mount end 221 of mount module 220. The second shim end 321 is closer to the first shim 310 on the basis that the projected distance of the first rotation shaft 212 to the fixed receiving end 221 is the same as the projected distance of the first rotation shaft 212 to the fixed receiving end 221. When the upper surface of first pad layer 310 and the upper surface of second pad layer 320 are in a horizontal plane, the gap therebetween is more reduced.

In the above implementation process, on the basis that the projection distance of the first rotation shaft 212 onto the fixed receiving end 221 and the projection distance of the first rotation shaft 212 onto the fixed receiving end 221 are the same as the upper limit, the second cushion end 321 protrudes out of the fixed receiving module 220, so that the second cushion end 321 can be closer to the first cushion 310. Further, the gap between first pad layer 310 and second pad layer 320 is smaller in the case where first pad layer 310 and second pad layer 320 are at the same level. Finally, the comfort of the sitting and lying structure 200 is further improved.

Referring to fig. 5, fig. 5 is a schematic diagram of a fourth structure of a sitting and lying structure 200 according to an embodiment of the application. In some alternative embodiments, the anchor receiving end 221 is projected to coincide with the second shim end 321.

That is, the second cushion end 321 is flush with the mount receiving end 221 in the vertical direction in fig. 5. In this way, the distance of the first rotation shaft 212 projected onto the fixing and receiving end 221 is the same as the upper limit of the distance of the first rotation shaft 212 projected onto the fixing and receiving end 221, and the second pad end 321 is maximally close to the first pad 310, so that the second pad end 321 can be supported by the fixing and receiving module 220, so as to ensure that the second pad 320 can be maximally supported by the fixing and receiving module 220.

Based on the combination of the foregoing embodiments, a preferred embodiment of the sitting and lying structure 200 may be obtained, as shown in fig. 6, and fig. 6 is a schematic view of a fifth structure of the sitting and lying structure 200 according to an embodiment of the present application. As can be seen in fig. 6, the first shim 310 is flush with the end of the first rotation receiving module 210 near the first rotation axis 212, and the second shim 320 is flush with the end of the fixed receiving module 220 near the first rotation axis 212.

In the above implementation process, on the basis that the projection distance of the first rotation shaft 212 projected onto the fixed receiving end 221 is the same as the projection distance of the first rotation shaft 212 projected onto the fixed receiving end 221, when the second cushion end 321 is flush with the fixed receiving module 220, the second cushion end 321 can be received by the fixed receiving module 220 and supported by the fixed receiving module 220. Further, with second cushion 320 more fully supported, the comfort of seating and sleeping structure 200 is further improved.

Referring to fig. 7, fig. 7 is a cross-sectional view of a first rotation receiving module 210 in a sitting and lying structure 200 according to an embodiment of the application. In some alternative embodiments, the first rotation receiving module 210 comprises a hollow module having a cavity therein. The hollow module includes a first surface 213 for laying a first mat 310 and a second surface 214 facing away from the first surface 213.

Illustratively, where the sitting and lying structure 200 is a medical bed 20 structure, the first rotation receiving module 210 may be a rotatable bed board in the medical bed structure and the fixed receiving module 220 may be a bed frame and a fixed bed board in the medical bed 20 structure. The rotatable bed plate and the fixed bed plate may be bed plates having cavities therein. The bed board with the cavity inside can be manufactured by adopting a hollow blow molding process.

In the above implementation, by making the first rotation receiving module 210 into a hollow structure, the weight of the sitting and lying structure 200 is reduced, and raw materials required for manufacturing are reduced.

Referring to fig. 8 in conjunction with fig. 7, fig. 8 is a schematic structural diagram of a first rotation receiving module 210 in a sitting and lying structure 200 according to an embodiment of the application. In some alternative embodiments, the first rotation shaft 212 comprises a through shaft that extends through the hollow module. The first surface 213 includes at least one first recess 2131 disposed on either side of the through axis and recessed toward the second surface 214. The first recess 2131 has a first recess bottom wall proximate to the second surface 214, and a first recess side wall surrounding the first recess bottom wall. The first concave side wall abuts against the penetrating shaft to limit the penetrating shaft to move along the direction except the length direction.

Since the through shaft extends through the entire hollow module, the portion of the through shaft located inside the hollow module will generally not be in contact with the first surface 213 or the second surface 214 or other surfaces of the hollow module, i.e. the portion of the through shaft will not have any bearing points. In the embodiment of the present application, under the abutting action of the first recess 2131, additional support may be provided for the portion of the through shaft located inside the hollow module, so as to improve the stability of the sitting and lying structure 200.

The number of the first concave portions 2131 at both sides of the through shaft may be 2, 3, 4, etc., and one skilled in the art may determine the specific number of the first concave portions 2131 according to the stability requirement of the sitting and lying structure 200, the size of the hollow module, etc., which is not particularly limited in the embodiment of the present application.

Further, regarding the arrangement of the first concave portions 2131 on the hollow module, the through axis may be a symmetry axis, and symmetrically distributed on two sides of the through axis; or may be located on both sides of the through axis and asymmetrically distributed.

In the above implementation process, the first surface 213 of the hollow module is provided with the first recess 2131 abutting against the through shaft, so that a support is provided for the portion of the through shaft located inside the hollow module, so that the rotary connection between the through shaft and the hollow module is more stable, and the stability of the sitting and lying structure 200 is further improved.

With continued reference to fig. 7 and 8, in some alternative embodiments, the second surface 214 includes second recesses 2141 disposed on opposite sides of the through axis and recessed toward the first surface 213. The second recess 2141 has a second recess bottom wall adjacent to the first surface 213, and a second recess side wall surrounding the second recess bottom wall. The second concave side wall is abutted against the penetrating shaft so as to limit the penetrating shaft to move along the direction except the length direction of the penetrating shaft; the second concave bottom wall is abutted with the first concave bottom wall.

On the basis of the first surface 213 of the hollow module being provided with the first recess 2131, the second surface 214 thereof is correspondingly provided with the second recess 2141, so as to support the portion of the through shaft located inside the hollow module with the first recess 2131.

In the above implementation process, by correspondingly arranging the second concave portions 2141 on the second surface 214 of the hollow module, on one hand, under the simultaneous support of the concave portions respectively located on the first surface 213 and the second surface 214, the stability of the rotational connection between the first rotation shaft 212 and the hollow module is further improved, and further, the stability of the sitting and lying structure 200 is further improved; on the other hand, the symmetrical structure of the first surface 213 and the second surface 214 facilitates the mold opening for manufacturing, thereby saving the manufacturing cost of the sitting and lying structure 200.

With continued reference to fig. 7 and 8, in some alternative embodiments, the hollow module includes a through-hole connection wall 215. The first surface 213 has a first through hole 2132 thereon, and the second surface 214 has a second through hole 2142 thereon. One end of the through hole connecting wall 215 is connected to the wall of the first through hole 2132, and the other end is connected to the wall of the second through hole 2142.

The number of the first through holes 2132 may be 1, 2, 3, etc., and those skilled in the art may determine the number of the first through holes 2132 according to factors such as the size of the first through holes 2132, the size of the hollow module, and the strength of the hollow module. The present application is not particularly limited in this regard. Among them, the influence of the first through hole 2132 on the strength of the hollow module will be explained in detail later.

The number of second through holes 2142 corresponds to the number of first through holes 2132. However, the specific locations and specific dimensions of the second through holes 2142 distributed on the second surface 214 may be identical to the locations and dimensions of the first through holes 2132 distributed therein, or may not be identical to each other.

In the specific process of manufacturing the hollow module having the first through hole 2132, the second through hole 2142 and the through hole connecting wall 215, a first manner may be adopted, in which the first through hole 2132 and the second through hole 2142 are respectively opened on the first surface 213 and the second surface 214 of the hollow module, and then the first through hole 2132 and the second through hole 2142 are connected by using the through hole connecting wall 215; a second way that can be adopted is to mold the hollow module having the first through hole 2132, the second through hole 2142, and the through hole connection wall 215 integrally.

Since the inside of the hollow module is hollow, the through hole connection wall 215 can support the first surface 213 and the second surface 214 of the hollow module to improve the strength of the hollow module.

It should be noted that whether the through hole connecting wall 215 is perpendicular to the first surface 213 and the second surface 214 generally depends on whether the positional relationship between the first through hole 2132 and the second through hole 2142 connected thereto is symmetrical, whether the dimensions of the two are the same, and so on. But even if the through hole connection wall 215 is not perpendicular to the first surface 213 or the second surface 214, it can still support the first surface 213 and the second surface 214.

In the above implementation, the through hole connection wall 215 connected between the first through hole 2132 and the second through hole 2142 plays a supporting role on the first surface 213 or the second surface 214. When the first surface 213 and/or the second surface 214 are subjected to external pressure urging the first surface 213 and the second surface 214 toward each other, the hollow module is prevented from collapsing to some extent.

Referring to fig. 9, fig. 9 is a perspective view of a sitting and lying structure 200 according to an embodiment of the application. In some alternative embodiments, the sit-and-lie structure 200 further comprises a second rotation receiving module 230 and a third rotation receiving module 240; the first rotation receiving module 210, the second rotation receiving module 230, and the third rotation receiving module 240 are distributed along a sliding direction of the second end of the third rotation receiving module 240. The first rotation receiving module 210 is rotatably connected to the fixed receiving module 220 through a first rotation shaft 212. The first end of the second rotation receiving module 230 is rotatably connected to the fixed receiving module 220 through a second rotation shaft 231. The second end of the second rotation receiving module 230 is rotatably connected to the first end of the third rotation receiving module 240 through a third rotation shaft 241. The first rotation shaft 212, the second rotation shaft 231, and the third rotation shaft 241 are parallel. The second end of the third rotation receiving module 240 is slidably coupled to the fixed receiving module 220.

Taking the medical bed 20 as an example, the first rotation receiving module 210 may be an adjustable bed board that mainly receives the back of the patient after the patient is lying on; the second rotation receiving module 230 may be an adjustable bed board for receiving mainly buttocks and thigh of a patient after the patient is lying thereon; the third rotation receiving module 240 may be an adjustable couch plate that receives primarily the calf portion of the patient after the patient is lying thereon. By adjusting the first rotation receiving module 210, the second rotation receiving module 230 and the third rotation receiving module 240, respectively, the patient can be seated and reclined on the patient bed comprising the seating and reclining structure 200 in the most comfortable and/or most suitable posture for receiving treatment.

In the above implementation process, the first rotation receiving module 210, the second rotation receiving module 230, and the third rotation receiving module 240 are adjustable, so that the sitting and lying structure 200 can be adjusted to a corresponding posture according to actual requirements. The comfort and applicability of the sitting and lying structure 200 are improved.

In summary, in the sitting and lying structure 200 and the medical bed 20 according to the embodiments of the present application, the rotating shaft of the rotating receiving module is disposed at a position away from the fixed receiving module 220 by a certain distance, so that the occurrence of wrinkles and arching of the cushion layer laid on the sitting and lying structure 200 during the rotation of the first cushion layer 310 along with the rotating receiving module is avoided to a certain extent. Through the arrangement of the rotation bearing end 211 and the first cushion layer end 311 which are flush in the vertical direction, and the arrangement of the fixation bearing end 221 and the second cushion layer end 321 which are flush in the vertical direction, the first cushion layer end 311 and the second cushion layer end 321 can be respectively borne by the rotation bearing module and the fixation support module, and are respectively supported by the rotation bearing module and the fixation support module. Further, with first cushion layer 310 and second cushion layer 320 more fully supported, the comfort of seating and sleeping structure 200 is also improved. In addition, the rotation receiving module is made into a hollow structure, so that the weight of the sitting and lying structure 200 is reduced, and raw materials required for manufacturing are reduced. Further, by arranging the first recess 2131 and the second recess 2141 abutting against the through shaft on the surface of the hollow module, a support is provided for the portion of the through shaft located inside the hollow module, so that the rotational connection between the through shaft and the hollow module is more stable, and the stability of the sitting and lying structure 200 is further improved. Further, the through hole connection wall 215 connected between the first through hole 2132 and the second through hole 2142 plays a supporting role for the first surface 213 or the second surface 214, improving the strength of the hollow module.
