[0024] The upper body structure of the vegetative patient care bed provided in this embodiment can be used outdoors or indoors, and has diverse functions.

[0025] The upper body structure of the vegetative patient care bed includes a back support shell 101 and a buttocks support shell 112. The back support shell 101 has an upper opening and is used to accommodate a back cavity of the vegetative patient's back. The buttocks support shell 112 has an upper opening and is used to accommodate a buttocks cavity of the vegetative patient's buttocks. When the vegetative patient is placed on the vegetative patient care bed, his back is placed in the back cavity, and his buttocks are placed in the buttocks cavity.

[0026] A transition structure is provided between the back support shell 101 and the hip support shell 112. A transition area with an upper opening is formed on the transition structure. The transition area is connected to the back cavity and the hip cavity. In this way, when the vegetative patient is put on the nursing bed, the waist is just in the transition area of ​​the transition structure, and the transition structure can also support the waist.

[0027] The transition structure is fixedly connected to the hip support shell 112 , and a translation structure is provided between the transition structure and the back support shell 101 , and the back support shell 101 and the hip support shell 112 move toward or away from each other through the movement of the translation structure.

[0028] The upper body structure of the vegetative patient care bed provided above is achieved by setting a translation structure between the transition structure and the back support shell 101, and the transition structure is fixedly connected to the hip support shell 112. Through the translation structure, the back support shell 101 can be moved toward or away from the hip support shell 112. In this way, the length distance between the back support shell 101 and the hip support shell 112 can be adjusted, that is, the length of the upper body structure can be adjusted to meet the needs of users with different height requirements.

[0029] The translation structure includes a socket in the back support shell 101 and a plug on the transition structure, wherein the plug is movably inserted in the socket. The distance between the back support shell 101 and the hip support shell 112 can be adjusted by inserting the plug into the socket to a certain depth.

[0030] An open slot 114 connected to the socket is provided on the back support shell 101. The open slot 114 extends along the length direction of the socket. A fastener is passed through the open slot 114 to fix the insertion strip in the socket. After the insertion strip is inserted into the socket, the fastener passes into the socket and presses the insertion strip to fix it.

[0031] The insert has an abutting surface facing the groove, which is recessed upward to form a recessed groove. The recessed groove extends along the length direction of the open groove 114. Blocks are respectively provided at both ends of the recessed groove, and the fastener is placed in the recessed groove.

[0032] In this way, by embedding it in the recessed groove, the position deviation of the fastener can be avoided, which plays a role in positioning and guiding. In addition, two blocks are provided, which can press against the fastener to limit the moving distance of the insertion strip in the socket and prevent the insertion strip from detaching from the socket.

[0033] The two sides of the recessed groove bar have inclined side walls, which are extended along the length direction of the recessed groove bar, the tops of the two inclined side walls are converged, the bottoms of the two inclined side walls are separated, and the two inclined side walls enclose a recessed groove bar that is larger at the bottom and smaller at the top.

[0034] Since the recessed groove has two inclined side walls, the fastener can be pressed more firmly inside the recessed groove under the inclined guidance of the inclined side walls during the process of pressing the recessed groove, and the inclined side walls can guide the fastener to embed into the recessed groove.

[0035] The fastener includes a pressing shaft and an operating head 116 connected to the pressing shaft. The operating head 116 is placed outside the insertion hole. The pressing shaft passes through the open groove 114, is embedded in the recessed groove, and presses against two inclined sides of the recessed groove.

[0036] The end of the pressing shaft forms a pointed pressing end, which has two inclined pressing surfaces, and the two pressing surfaces are respectively pressed against the two inclined side surfaces. The pressing between the pressing shaft and the insert can be made more stable by the pressing of the pressing surfaces and the inclined side surfaces.

[0037] The transition structure includes a transition belt and a fixing belt 103, which are arranged in sequence along the extension direction from the back support shell 101 to the hip support shell 112; the insert is set on the transition belt, and the fixing belt 103 is fixedly connected to the hip support shell 112; the transition belt and the fixing belt 103 are rotatably connected.

[0038] The two ends of the transition zone and the two ends of the fixing belt 103 are bent and extended upwards, and the transition zone and the fixing belt 103 enclose a transition area. In this way, when the vegetative patient lies on the nursing bed, the back is placed in the back cavity, the buttocks are placed in the buttocks cavity, and the waist can be placed in the transition area to avoid the waist being empty.

[0039] A fixing seat is provided on the lower surface of the transition zone, and bumps protrude downward on both sides of the fixing seat. One end of the insertion strip is fixed on the bumps, and the other end of the insertion strip is inserted into the socket. Two bosses 118 are provided on the lower surface of the back support shell 101, and sockets are provided in the bosses 118.

[0040] A support seat 109 is provided on the fixing belt 103, the hip support shell 112 is fixedly connected to the support seat 109, and the transition belt is rotatably connected to the support seat 109, so that the back support shell 101 can rotate relative to the hip support shell 112 to achieve a twisting effect.

[0041] The support seat 109 is connected to a power element 110 , and the transition zone is connected to a torsion element. The power element 110 drives the torsion element to twist, so that the back support shell 101 twists relative to the hip support shell 112 .

[0042] The power element 110 includes a motor arranged on a support seat 109, a rotating shaft 111 is connected to the motor, and a driving meshing tooth is arranged on the rotating shaft 111; the torsion element includes a torsion plate 108 fixed on the transition zone, and a torsion meshing tooth is arranged on the outer periphery of the torsion plate, and the driving meshing tooth meshes with the torsion meshing tooth. Thus, through the rotation of the rotating shaft 111, the driving meshing tooth drives the kneading drive with the torsion meshing tooth, and the torsion plate is driven to torsion.

[0043] The support seat 109 is strip-shaped, and both sides of the support seat 109 extend along the width direction of the back support shell 101, and the middle part of the support seat 109 protrudes downward away from the back support seat 109 to form a mounting platform, and the power element 110 is fixed on the mounting platform. In this way, the installation of the power element 110 is convenient.

[0044] The fixing belt 103 includes a flat belt, and the support base 109 is fixedly connected to the flat belt, so as to facilitate the installation and fixation of the support base 109.

[0045] The fixing belt 103 is connected with a reinforcing strip 113, which is connected to the lower surface of the fixing belt 103 and extends along the length direction of the fixing belt 103; the support seat 109 is fixedly connected to the lower surface of the reinforcing strip 113. The reinforcing strip 113 is arranged on the lower surface of the fixing belt 103 to support and stabilize the fixing belt 103 and facilitate the installation of the support seat 109.

[0046] The two sides of the reinforcing strip 113 extend out of the two sides of the back support shell 101, and bend and extend toward the hip support shell 112, forming a bent extension section 104 for connecting with the leg support shell 200. In this way, the upper part of the leg support shell 200 of the nursing bed can be connected to the extension section 104 of the reinforcing strip 113, which facilitates the structural matching of the entire nursing bed.

[0047] A fixing seat 105 is provided on the transition zone, and the fixing seat 105 is torsionally connected to the supporting seat 109 via a connecting shaft, and the torsion disk 108 is fixedly connected to the fixing seat 105. By providing the fixing seat 105, the rotation connection between the back supporting shell 101 and the hip supporting shell 112 is facilitated.

[0048] The twisting disk 108 is fan-shaped, the upper part of the twisting disk 108 is fixed on the fixing seat 105, the lower part of the twisting disk 108 has an arc surface, the length direction of the arc surface extends along the width direction of the back support shell 101, and the twisting meshing teeth are arranged on the arc surface.

[0049] In this way, the driving meshing teeth are rotated by the rotation of the rotating shaft 111, and then the torsion disk 108 is driven to torsion. In order to prevent the driving meshing teeth of the rotating shaft 111 from disengaging from the torsion meshing teeth, limit bars are respectively arranged downward at the two ends of the arc surface, and the limit bars are bent and extended toward the bottom of the torsion disk 108. The two limit bars have inner side surfaces arranged oppositely, and the inner side surfaces of the limit bars form limited meshing teeth. When the torsion disk 108 swings to the end and pinches the rotating shaft 111, the driving meshing teeth of the rotating shaft 111 are also engaged with the limit meshing teeth. In this way, the torsion limit position of the torsion disk 108 can be limited without causing collision.

[0050] The upper part of the inner side surface of the limit bar is provided with the above-mentioned limit meshing teeth, and the lower part of the inner side surface of the limit bar is flat. In this way, when the rotating shaft 111 cooperates with the limit meshing teeth and rotates to the lower part of the inner side surface of the limit bar, idle rotation will be formed to avoid exceeding the limit range of the limit bar.

[0051] For better flexible cooperation, a flat elastic layer is provided at the lower part of the inner side surface of the limiting strip.

[0052] The fixing seat 105 is strip-shaped and extends along the width direction of the back support shell 101. The middle part of the fixing seat 105 protrudes downward to form a protruding block, and the upper part of the twisting plate 108 is fixed on the protruding block.
