[0028] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods.

[0029] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, in an embodiment of the present invention, a multifunctional side-turning electric hospital bed includes a bed body 1, the bottom of the bed body 1 is supported by supporting legs 2, a connecting opening is provided in the center of the bed body 1, two sets of flip plates 4 are rotatably installed in the connecting opening, and the near sides of the two sets of flip plates 4 are rotatably installed in the connecting opening through connecting shafts, a transfer blanket 3 is laid on the upper side of the bed body 1, and a set of winding shafts 5 are respectively installed at the bottom of both sides of the bed body 1. The two sets of winding shafts 5 are used to reel in the two sides of the transfer blanket 3, and the ends of the two sets of winding shafts 5 are coaxially connected to the two sets of drive shafts 6 provided on one side of the bed body 1 through a meshing gear plate group 23. The two sets of drive shafts 6 are provided at the bottom of the side of the bed body 1 where the winding shaft 5 is not installed, and the two sets of drive shafts 6 are connected by a first transmission belt 7, wherein the end of one set of drive shafts 6 is connected to the screw assembly provided at the bottom of the bed body 1 through a bevel gear group, and the screw assembly is used to drive the two sets of sliding platforms 11 at the bottom of the bed body 1 to slide linearly, and the two sets of sliding platforms 11 are respectively slidably installed on both sides of the bed body 1 where the winding shaft 5 is not provided;

[0030] A power shaft 8 is rotatably installed between the two sets of sliding tables 11, and a lifting assembly 9 is installed on the power shaft 8. The lifting assembly 9 supports and flips the corresponding connected flip plate 4. A set of sliding plates 20 are respectively installed on both sides of the sliding table 11. A set of elastic telescopic shafts 14 are installed on the two sets of sliding plates 20 in a mirror-image manner. The near ends of the two sets of elastic telescopic shafts 14 are connected to the power shaft 8 through the transmission assembly 10. The other end of the elastic telescopic shaft 14 is coaxially mounted with a first bevel gear 25, which can be engaged with the second bevel gear 26 at the end of the winding shaft 5. The bed body 1 is provided with an ejection assembly 19 on the side close to the communicating opening;

[0031] When the flip plate 4 is driven by the lifting assembly 9 to flip upward, the transmission drives the ejection assembly 19 to extend out of the bed body 1, and drives the elastic telescopic shaft 14 to extend so that the first bevel gear 25 at its end engages with the second bevel gear 26. At the same time, the unlocking assembly 15 on the sliding plate 20 unlocks the meshing gear disk group 23, so that the winding shaft 5 and the drive shaft 6 are disengaged.

[0032] like Figure 3 and Figure 4 As shown, in the embodiment of the present invention, the meshing gear disc group 23 includes a fixed gear disc 2301 and a movable gear disc 2302, and the fixed gear disc 2301 is coaxially mounted on the end of the driving shaft 6 close to the winding shaft 5, and the movable gear disc 2302 is linearly slidably mounted on the corresponding end side of the winding shaft 5, and is elastically connected to the fixed plate provided on the shaft body of the winding shaft 5 through the return spring 1502.

At this time, the transfer blanket 3 can be moved by rotating the two groups of winding shafts 5, and the patient can be displaced and moved synchronously. The transfer blanket 3 has a large area and is in contact with the patient's body. At this time, the patient can be dragged to move by winding the transfer blanket 3, which can minimize the damage to the patient during the transfer process.

[0033] like Figure 2 and Figure 4 As shown, in the embodiment of the present invention, the screw assembly includes a driving screw 12 and a guide rod 13, and the driving screw 12 and the guide rod 13 are respectively arranged on both sides of the bed body 1, wherein the driving screw 12 is rotatably mounted on the side of the bed body 1 where the winding shaft 5 is not provided, and one end thereof is transmission-connected to a group of driving shafts 6 through a bevel gear set, and its rod body forms a spiral pair transmission with a group of sliding tables 11, and the guide rod 13 is fixedly mounted on the other side of the bed body 1, and is slidingly connected to the other group of sliding tables 11 in a limited position;

[0034] Furthermore, the bevel gear set includes a main bevel gear 1 22 and a main bevel gear 2 21 that are meshed and connected. The main bevel gear 1 22 and the main bevel gear 2 21 are coaxially mounted on the end portions of the drive shaft 6 and the drive screw 12, respectively. In the present invention, the drive screw 12 is driven by the main bevel gear 1 22 and the main bevel gear 2 21 to be connected to the drive shaft 6, so that when the patient is moved by the transfer blanket 3 and is in an area biased to one side of the bed 1, the two sets of sliding blocks 1503 are moved to the bottom of the patient by the rotation of the drive screw 12 and the guidance of the guide rod 13, and synchronously drive the power shaft 8 and the lifting assembly 9 to be connected to the flip plate 4 directly below the patient, thereby realizing that the positions of the power shaft 8 and the lifting assembly 9 are synchronously positioned and moved during the patient's movement.

[0035] Further, such as Figure 2 and Figure 3 As shown, in the present invention, a first motor 17 is provided at the bottom of the bed body 1. The first motor 17 is installed at one end of the driving screw 12 to drive the driving screw 12 to rotate. Moreover, due to the transmission connection between the driving shaft 6 and the driving screw 12, the first motor 17 of the present invention can also be arranged and installed at one end of the driving shaft 6 to drive the driving shaft 6 to rotate.

[0036] like Figure 7 As shown, in the embodiment of the present invention, the lifting assembly 9 includes multiple groups of driving inner nuts 902, transmission rods 903, lifting blocks 904 and transmission sliders 905. The power shaft 8 is provided with external threads 901 for spirally connecting the multiple groups of driving inner nuts 902. One end of the multiple groups of transmission rods 903 is rotatably connected to the corresponding driving inner nuts 902, and the other end is rotatably connected to the corresponding lifting blocks 904. The upper end of the lifting block 904 is rotatably connected to the corresponding transmission slider 905 at the bottom of the flip plate 4. The bottoms of the two groups of flip plates 4 are respectively provided with a group of limiting rails 906, and the two groups of limiting rails 906 can be rotated between the two groups of flip plates. The plates 4 are connected and docked when placed horizontally. In the present invention, when the lifting assembly 9 is used to lift and flip the flip plate 4, the second motor 18 drives the power shaft 8 to rotate, and the multiple groups of external threads 901 with different rotation directions on the power shaft 8 are driven to drive multiple groups of driving internal nuts 902 to move along the axial direction of the power shaft 8, and the corresponding transmission rod 903 drives the lifting block 904 to move upward. At the same time, during the movement of the lifting block 904, its rotating connected transmission slider 905 can rotate synchronously with the flip plate 4, thereby avoiding the lifting block 904 from getting stuck with the flip plate 4 during the lifting process.

[0037] like Figure 3 and Figure 4As shown, in an embodiment of the present invention, the transmission assembly 10 includes a transmission shaft 1001, a second transmission belt 1002, a secondary bevel gear 1003 and two sets of secondary bevel gears 2 1004. The transmission shaft 1001 is rotatably mounted on the sliding table 11 and is transmission-connected to the power shaft 8 through the second transmission belt 1002. The secondary bevel gear 1003 is coaxially mounted on the transmission shaft 1001. The two sets of secondary bevel gears 2 1004 are respectively meshed and connected to both sides of the secondary bevel gear 1003 and are coaxially mounted on the ends of the corresponding elastic telescopic shafts 14. The present invention drives the rotation of the power shaft 8 to the two sets of elastic telescopic shafts 14 by setting the transmission assembly 10, so that when the elastic telescopic shaft 14 is transmission-connected to the corresponding winding shaft 5, the power shaft 8 rotates, and while driving the lifting assembly 9 to lift the flip plate 4, it can drive the corresponding connected winding shaft 5 to rotate, thereby realizing the delivery of the transfer blanket 3.

[0038] Further, such as Figure 6 As shown, the ejection assembly 19 includes a movable cone wheel 1905, an ejection rod 1903, a transmission wedge 1902 and a driving wedge 1901. The movable cone wheel 1905 is coaxially installed at the end of the movable shaft 1401 in the elastic telescopic shaft 14. The ejection rod 1903 is vertically slidably installed in the connecting hole opened on the bed body 1, and its upper end is fixedly connected to the bottom of the transmission wedge 1902. The transmission wedge 1902 and the driving wedge 1901 are slidably installed in the positioning slide groove provided on one side of the connecting opening of the bed body 1. The transmission wedge 1902 is slidably connected to the inclined side of the driving wedge 1901. One end of the driving wedge 1901 is elastically connected to the side wall of the positioning slide groove by a support spring 1904, and the other side extends out of the positioning slide groove. The bottom of the flip plate 4 is provided with an arc plate 24, and the arc plate 24 is used when the flip plate 4 When flipping, the driving wedge 1901 is continuously pressed and limited. When the flip plate 4 is forced to flip upward, its side surface can be squeezed with the side surface of the driving wedge 1901, and the driving wedge 1901 is forced to retract into the positioning slot. At this time, the support spring 1904 is in an extruded state, and the inclined surface on the other side of the driving wedge 1901 squeezes the transmission wedge 1902, so that the transmission wedge 1902 moves downward, and drives the ejector rod 1903 to move downward. The bottom of the ejector rod 1903 acts on the inclined surface of the movable cone wheel 1905, squeezing the movable cone wheel 1905 and the movable shaft 1401 to move in the direction close to the outside of the bed body 1, so that the first bevel gear 25 at the end of the movable shaft 1401 can mesh with the second bevel gear 26 at the end of the winding shaft 5, and the transmission connection between the power shaft 8 and the winding shaft 5 is realized through the elastic telescopic shaft 14;

[0039] Further, if Figure 4As shown, the unlocking assembly 15 includes a pushing rod 1504 and a movable cone wheel 2 1501, and the pushing rod 1504 is slidably installed on the sliding plate 20 through a sliding block 1503. The sliding plate 20 is rotatably connected to the movable shaft 1401 of the elastic telescopic shaft 14, and the movable cone wheel 2 1501 is coaxially fixedly installed at the bottom of the movable gear plate 2302. When the above-mentioned movable shaft 1401 is driven by the ejection rod 1903 to displace toward the outside of the bed body 1, the pushing rod 1504 located on the sliding plate 20 can abut against the inclined side of the movable cone wheel 2 1501 at the bottom of the movable gear plate 2302, and push the movable gear plate 2302 to move away from the drive shaft 6, so that the movable gear plate 2302 is disengaged from the fixed gear plate 2301. At this time, the winding shaft 5 and the drive shaft 6 are unlocked, and the winding shaft 5 can rotate independently of the drive shaft 6.

[0040] like Figure 1 As shown, in the embodiment of the present invention, heating wires are embedded in the transfer blanket 3 , and the heating wires are used to heat the surface of the bed 1 , so that the patient feels warm when lying on the bed 1 and maintains the patient's body temperature.

[0041] In summary, in the present invention, a transfer blanket 3 is provided on the bed body 1, and the transfer blanket 3 can be transferred by rotating the winding shafts 5 on both sides of the bottom of the bed body 1, and drives the patient lying on the transfer blanket 3 to perform lateral displacement. Specifically, when the patient needs to be turned sideways, the two sets of winding shafts 5 can be used to synchronously rotate to drive the transfer blanket 3 to move, and the patient can be transferred to one side area of the bed body 1, which is deviated from the center of the bed body 1. At the same time, the power shaft 8 and the lifting assembly 9 can be driven by the screw assembly to synchronously adjust the lateral position, and the power shaft 8 and the lifting assembly 9 are moved to the bottom of the turning plate 4 at the bottom of the patient. By rotating the power shaft 8, the turning plate 4 at the bottom of the patient is driven to turn, and the patient is pushed to the other side, thereby assisting the patient in the side turning operation;

[0042] At the same time, when the flip plate 4 flips, its side surface and the arc-shaped plate 24 are squeezed against the driving wedge 1901 in the positioning slot, and the driving wedge 1901 is squeezed and inserted into the positioning slot, and cooperates with the transmission action of the transmission wedge 1902 and the ejection rod 1903 to drive the elastic telescopic shaft 14 located at the bottom of the bed 1 to extend, so that the two ends of the elastic telescopic shaft 14 are respectively connected to the winding shaft 5 and the power shaft 8, so that when the power shaft 8 rotates to drive the lifting assembly 9 to rotate the flip plate 4, the winding shaft 5 on the corresponding side can be driven to rotate synchronously, thereby realizing the feeding of the transfer blanket 3 and avoiding the problem that the transfer blanket 3 is damaged by being pulled when the flip plate 4 rotates.

[0043] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
