[0036] There is a hydraulic pushing device 3 arranged transversely at the transverse hole b, and two parallel transverse grooves c are installed at the transverse hole b. The two transverse grooves c are respectively located on the corresponding transverse bosses 122. The hydraulic pushing device 3 includes two hydraulic pumps 31 and two transverse telescopic rods 32. The baffle 124 blocks the hydraulic pump 31. Each transverse telescopic rod 32 is arranged in one of the transverse grooves c. One end of each transverse telescopic rod 32 is connected to one of the hydraulic pumps 31, and the other ends of the two transverse telescopic rods 32 are detachably connected to the seat cushion 222. Each transverse telescopic rod 32 includes a rod 1 321, a rod 2 322, a rod 3 323 and a rod 4 323, which are gradually increasing in width and connected in sequence. The interiors of the rod 1 321, the rod 2 322, the rod 3 323 and the rod 4 323 are connected. The hydraulic pump 31 is connected to the end of the rod 1 321, and the end of the rod 4 323 is detachably connected to the seat cushion 222. A sliding block d that can slide laterally is installed between the two parallel transverse groove rails c. The sliding block d and the side of the mattress 1 facing the seat cushion 222 and the end faces of the two rods 323 are all recessed to form a slide groove e with parallel longitudinal holes that penetrate each other. The slide groove e is specifically opened on the side of the base pad 12. One end of the slide groove e is an open entrance end, and the other end is a closed end. The seat cushion 222 protrudes outwardly from the side of the mattress 1 to form a slider f that is slidably installed in the slide groove e. The bottom of the seat cushion 222 is provided with a slider g that matches the slide groove plate 215, and the slider f is located on the end face of the slider g.

[0037] The wheelchair 2 is pressed against one side of the mattress 1 in the transverse direction through a reset device 4. When the wheelchair 2 is pressed against one side of the mattress 1 in the transverse direction, the cushion 22 is matched with the hydraulic pushing device 3 and is moved transversely to the longitudinal hole a by the hydraulic pushing device 3. The reset device 4 includes an electromagnet 41 located at the open inlet end of the slide groove e and an iron sheet 42 located on the end surface of the slider f.

[0038] A voice control device 5 is disposed inside the head pad 221 of the seat pad 22 . The voice control device 5 includes a recording speaker 51 and a voice processing module 52 . The recording speaker 51 is connected to the voice processing module 52 .

[0039] A driving device 6 for lifting and lowering the backrest 223 is provided at the connecting position of the seat cushion 222 and the backrest 223 of the chair cushion 22. A driving device 6 for lifting and lowering the leg pad 224 is also provided at the connecting position of the seat cushion 222 and the leg pad 224. A driving device 6 for lowering and raising the armrest 225 is also provided at the connecting position of the armrest 225 and the seat cushion 222. Each of the driving devices 6 includes a servo 61 and a rotating gear 62. A gear 63 installed on the output shaft of the servo 61 meshes with the rotating gear 62. The rotating gears 62 are all installed on the seat cushion 222. The servo 61 and the gear 63 are respectively installed on the backrest 223, the leg pad 224 and the armrest 225.

[0040] The hydraulic pushing device 3, the resetting device (resetting module) 4, the voice control device (voice control module) 5 and the driving device (control module) 6 are all connected to a control device 7 to realize intelligent control of the wheelchair mattress.

[0041] When in use, the voice control device can be used to conveniently and directly transmit instructions, so that the steering engine 61 operates to first lift the backrest 223 and leg pad 224 of the seat cushion 22 by 15 degrees, and at the same time raise the armrest 225, so as to prevent the elderly from sliding to the end of the bed and causing unknown dangers during the lifting of the backrest 223. The air pump device 121 starts to discharge gas, so that the lifting cushion 11 drops to a certain height, the steering engine 61 rotates to rotate the backrest 223 to a comfortable position, and the hydraulic push device 3 pushes the seat cushion 22 onto the chair frame 21 through the transverse groove rail c. The seat cushion 22 and the chair frame 21 are fastened together through the slider 2g at the bottom of the seat cushion 222 and the slide plate 215. This completes the process of converting the bed into a wheelchair.

[0042] When the old man issues a reset instruction, the electromagnet 41 in the reset device 4 begins to generate magnetic force, and the old man drives the wheelchair to the electromagnet 41 of the reset device 4. Under the magnetic force of the electromagnet 41, the slider f on the side of the seat cushion 222 is embedded in the slide groove e. Then the hydraulic pump 31 in the hydraulic push device 3 drives the transverse telescopic rod 32 to shrink. The seat cushion 22 returns to the longitudinal hole a of the lifting cushion 11 through the transverse groove track c, and each steering gear 61 makes the backrest 223, leg pad 224, and armrest 225 become flat, and the air pump device 121 starts to pump air to make the lifting cushion 11 rise to the original height. The process of converting from a wheelchair to a bed is completed.

[0043] When the bed is converted into a wheelchair, the two hydraulic pumps 31 suck oil and increase pressure, so that the push rods 1 321, rod 2 322, rod 3 323 and rod 4 323 on both sides are extended, and the extension order is rod 4 323, rod 3 323, rod 2 322, rod 1 321. When the wheelchair is converted into a bed, the two hydraulic pumps 31 suck oil and reduce pressure, and retract the push rods 1 321, rod 2 322, rod 3 323 and rod 4 323 on both sides, and the retraction order is rod 4 323, rod 3 323, rod 2 322, rod 1 321.

[0044] This detachable voice-controlled intelligent wheelchair mattress device allows the elderly to travel independently and meet their life needs, which is conducive to rehabilitation and improving the quality of elderly care, reduces the probability of bumps and falls for the elderly, and greatly reduces the pressure on children to accompany their care.
