[0045] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0046] As Figures 1 to 22 shown, a multifunctional nursing bed includes a bed frame B provided with a half-width mattress 1 and a foldable wheelchair A1. A wheelchair docking recess C for docking the wheelchair A1 and allowing the wheelchair A1 to be flattened into a wheelchair bed A2 is provided on one side of the bed frame B. A locking mechanism is provided between one end face of the wheelchair A1 and the bed frame B, and the wheelchair A1 is connected to the side edge of the bed frame B by the locking mechanism along the side; a lifting plate 2 is rotatably connected to one end corresponding to the head of the bed in the wheelchair docking recess C, and after the lifting plate 2 is turned flat upward, it forms a headrest part of the wheelchair bed A2; a tail bed board 3 is rotatably connected to one end corresponding to the end of the bed in the wheelchair docking recess C, and after the tail bed board 3 is turned flat upward, it abuts against the upper side of the end of the wheelchair bed A2 at the end of the bed.

[0047] After the wheelchair A1 and the bed frame B of this nursing bed are connected into one body by using the locking mechanism, the wheelchair A1, the lifting plate 2 and the tail bed board 3 are further flattened, and the wheelchair bed A2 cooperates with the lifting plate 2 and the tail bed board 3 to lengthen the wheelchair bed.

[0048] The lifting plate 2 of this nursing bed can be turned flat upward, so that the lifting plate 2 replaces the headrest part of the wheelchair bed A2, preventing the user from sitting on the headrest of the wheelchair from causing the wheelchair bed A2 in the flattened state to tip over. Moreover, the lifting plate 2 turned flat upward can also be used as a folding table, which can endow the lifting plate with multifunctional features, with a simple structure and convenient use.

[0049] A bedside side C1 and two opposite bedside sides C2 are provided on the wheelchair docking recess C. In this embodiment, the lifting plate 2 is rotatably connected to the bedside side C2 corresponding to the head of the bed in the wheelchair docking recess C.

[0050] The bed frame B includes a head bed frame 23. At least part of the head bed frame 23 is used to define the bedside side C2 of the wheelchair docking recess C. The lifting plate 2 is rotatably connected to the inner side of the head bed frame 23, and when the lifting plate 2 is turned flat, the rear end side of the lifting plate 2 is limited and abuts against the top surface of the head bed frame 23; it plays a limiting role when the lifting plate 2 is turned flat upward. In addition, the head bed frame 23 can directly support the lifting plate 2 to a certain extent, which helps to improve the load-bearing capacity of the lifting plate 2 and improve the stability.

[0051] The width of the lifting plate 2 matches the width of the wheelchair parking recess C; the width of the lifting plate 2 is preferably the same as the width of the wheelchair parking recess C, so that the lifting plate 2 can match the width of the wheelchair after being flattened to form an integrated bed surface.

[0052] The locking mechanism includes a lock structure 4 and an axis structure 5 connected to the end surface of one side of the wheelchair A1 at the front and rear sides respectively, and a lock structure 6 and a hook structure 7 connected to the side edges of the recessed position at intervals on the left and right. The lock structure 6 and the hook structure 7 are respectively arranged corresponding to the lock structure 4 and the hook structure 7. The wheelchair A1 is first hinged to the hook structure 7 through the axis structure 5 on the rear side, and then buckled with the lock structure 4 and the lock structure 6 on the front side, so that the wheelchair A1 is locked to the bed frame B by the side.

[0053] This wheelchair first uses the flexibility of the front universal wheel group 15 to continuously adjust the position of the rear side of the wheelchair during the backward movement of the wheelchair, so that the shaft structure 5 is quickly hinged with the hook structure 7, so that the shaft structure 5 forms a rotation axis, and the locking structure 4 and the lock body structure 6 are kept in a concentric circle route, and then the front side of the wheelchair is pushed to the edge. At the same time, the locking structure 4 and the lock body structure 6 are locked, so that the wheelchair can be stably locked on the side of the bed frame B. The connection is firm and the disassembly and assembly operation is simple, which better reduces the gap between the wheelchair and the bed frame B after it is pulled to the edge, and better ensures the stability of pulling to the edge.

[0054] In other embodiments, the positions of the locking structure 4 and the lock body structure 6 can be swapped with each other, the positions of the shaft structure 5 and the hook structure 7 can be swapped with each other, and even the positions of the locking structure 4 and the lock body structure 6 are swapped with the positions of the shaft structure 5 and the hook structure 7.

[0055] It also includes an unlocking structure 64 for triggering the unlocking of the lock body structure 6, and the unlocking structure 64 is transmission-connected to the lock body structure 6, and the unlocking structure 64 is connected to the bed frame B; when the wheelchair needs to be disassembled from the bed frame B, it is only necessary to drive the unlocking structure 64 to unlock the front side of the wheelchair, and then slide the shaft structure 5 out of the hook structure 7 to complete the unlocking, which is simple to operate.

[0056] Specifically, the hook structure 7 includes a hook seat 71, and a slide groove 72 opening toward the lock body structure 6 is provided on the hook seat 71; the shaft structure 5 includes a roller bracket 51 extending outward, and the roller bracket 51 is connected to a shaft body 52 hinged in the slide groove 72 through an opening; the slide groove 72 facilitates the cooperation between the shaft body 52 and the hook seat 71, and after the shaft body 52 slides into the slide groove 72, the rotation axis function can be realized.

[0057] The latch structure 4 includes a latch base 401, and a latch ring 402 is connected to the latch base 401; the lock body structure 6 includes a lock body housing 61, a lock hole 62 adapted for the latch ring 402 to protrude into is formed on the lock body housing 61, a fastener 63 is rotatably connected inside the lock body housing 61, a fastening portion 631 for hooking the latch ring 402 is provided at one end of the fastener 63, and the other end is in transmission connection with an unlocking structure 64; after the latch ring 402 is pushed into the lock hole 62, under the elastic action of the fastener 63, its fastening portion 631 is buckled into the hollow position of the latch ring 402 to achieve final locking.

[0058] The roller bracket 51 includes a pair of L-shaped roller ears 511 arranged up and down. One section of the L-shaped roller ear 511 is welded to the rear side of the wheelchair main body 1, and the other section extends outward from the wheelchair main body 1, and a roller 521 is provided between the ends. A roller 522 is rotatably connected to the roller 521, and the roller 522 and the roller 521 form a shaft body 52; when the roller 522 can rotate with the shaft body 52 as the rotation axis, the rotation reduces friction, and the wheelchair rotates more smoothly and quietly.

[0059] Long groove edges 721 and short groove edges 722 are respectively provided on both sides of the chute 72. The short groove edge 722 is arranged on the side close to the wheelchair main body 1, and an introduction bevel edge 723 is provided at one end of the short groove edge 722 close to the opening.

[0060] The long groove edge 721 and the short groove edge 722 are used to make the chute 72 form an inclined opening, which helps the shaft body 52 to slide into the chute 72, and the introduction bevel edge 723 helps the shaft body 52 to slide into the deepest part of the chute 72. At this time, the chute 72 and the shaft body 52 form a clearance fit. When rotating as the rotation axis, the wheelchair will not have a loose gap, and it can ensure that the latch structure 4 and the lock body structure 6 are on a concentric circle route.

[0061] The unlocking structure 64 includes a switch fixing seat 641, a switch pedal 642 and a brake wire 643. The rear side of the switch pedal 642 is rotatably connected to the switch fixing seat 641. One end of the brake wire 643 is connected to the switch pedal 642, and the other end is connected to the other end of the fastener 63. And a spring for driving the fastener 63 to reset is sleeved on the brake wire 643.

[0062] When unlocking, the user only needs to step on the switch pedal 642 to make the switch pedal 642 pull the brake wire 643, and the brake wire 643 will drive the fastener 63, and the fastener 63 will release the locking of the latch ring 402. The caregiver can pull the front side of the wheelchair away from the bed frame B. After the user releases the switch pedal 642, under the elastic potential energy of the spring, the fastener 63 can be driven to automatically reset and wait for the next buckling.

[0063] A small bed end frame 8 is provided at the end of the wheelchair parking recess C, and the small bed end frame 8 is movably connected to the end of the bed frame B through a connecting structure. The upper side of the tail bed board 3 is flipped and connected to the inner side of the small bed end frame 8 through a plurality of combination pages 42. The outer side of the small bed end frame 8 is connected to a movable end plate 92 that can open or enclose the wheelchair parking recess C; the movable end plate 92 is fixed on the small bed end frame 8. The small bed end frame 8 has good structural strength, can keep the movable end plate 92 flat, and is easy to install, so that the movable end plate 92 can be made of other materials different from the small bed end frame 8.

[0064] This nursing bed has a movable end plate 92 at the end, so that the wheelchair is no longer limited to being docked in the wheelchair parking recess C from the side of the nursing bed. The wheelchair can be pushed into or out of the wheelchair parking recess C from the side, head or foot of the bed, thereby reducing the restriction on the use of the left and right spaces of this nursing bed, greatly improving the convenience and flexibility of operating the wheelchair, and having a simple structure and being easy to use.

[0065] In this embodiment, the head and foot of the bed frame B are connected to end plates 9, and a wheelchair parking recess C is enclosed on three sides between the two end plates 9 and the bed frame B. The end plate 9 at the foot of the bed is divided into a fixed end plate 91 and a movable end plate 92. The fixed end plate 91 matches the width of the bed frame B and is fixedly connected to the foot of the bed frame B.

[0066] The connecting structure includes a plurality of groups of connecting hinges 24, and the inner side of the small bed tail frame 8 is hinged with the bed frame B through a plurality of groups of connecting hinges 24, and is connected to the external space of the bed frame B to drive the movable end plate 92 to flip and open the wheelchair parking recess C; the small bed tail frame 8 and the movable end plate 92 are kept connected to the bed frame B through the connecting hinges 24, which is convenient to flip and simple to operate.

[0067] The bottom of the small bed tail frame 8 is assembled and connected with a universal caster 25 on the outer side; the universal caster 25 can provide support for the outer side of the small bed tail frame 8, and during the operation of the movable end plate 92, the turning action is smoother, with less friction and reduced noise.

[0068] The wheelchair A1 includes a seat frame 11, the rear side of the seat frame 11 is flipped and hinged with a back frame assembly 12, the upper side of the back frame assembly 12 is connected to a high backrest assembly 10, and the high backrest assembly 10 can be disassembled or flipped backward to avoid the upward flipped lifting board 2 when the wheelchair A1 is flattened.

[0069] The bottom of the seat frame 11 is also connected to a front universal caster set 15 and a rear caster set 16 .

[0070] A high-back component 10 is added to this wheelchair, enabling the user's head to be supported when sitting or when the wheelchair is flattened into a wheelchair bed alone. Moreover, the high-back component 10 can be disassembled or folded backward relative to the backrest component 12. When it can be combined with a nursing bed to form a larger bed body, the length of the wheelchair bed can be reduced, the center of gravity of the wheelchair bed can be shifted towards the middle, the stability of the wheelchair bed can be improved, and the tipping of the wheelchair bed caused by the weight-bearing at the position of the high-back component 10 can be avoided.

[0071] The high-back component 10 includes a high-back frame 1001. Both ends of the high-back frame 1001 are respectively connected to the upper side of the backrest component 12 through a folding-back device assembly 1002 in a flip manner. A high-back cushion 1003 is sleeved on the high-back frame 1001. The high-back cushion 1003 can be a beach net, and the headrest 1004 is connected to the front side of the high-back cushion 1003.

[0072] A handrail tube 1005 is also connected to the high-back frame 1001. The handrail tube 1005 extends towards the back side of the high-back frame 1001, and a brake handle assembly 1006 for controlling the rear caster group 16 is connected to the middle of the handrail tube 1005. It is convenient for the caregiver to push the multifunctional wheelchair by using the handrail tube 1005, and installing the brake handle assembly 1006 on the handrail tube 1005 is convenient for the caregiver to operate and control the start and stop of the wheelchair.

[0073] The wheelchair A1 further includes a footrest bracket 13 and a footrest frame 14. The footrest bracket 13 is rotatably hinged to the front side of the seat frame 11, and the footrest frame 14 is rotatably hinged to the front side of the footrest bracket 13. When the wheelchair A1 is flattened into a wheelchair bed A2, the tail bed board 3 abuts against the upper side of the footrest frame 14. When the bed frame is used in combination with the flattened wheelchair bed, first turn the tail bed board 7 upward to the unfolded position so that the tail bed board 7 can abut against the upper side of the footrest frame, which can fill the depression caused by the footrest frame without a mattress.

[0074] The backrest component 12 includes a backrest frame 121 and a backrest 122. The backrest frame 121 is rotatably hinged to the rear side of the seat frame 11, and a slide rail component 123 is provided on the backrest frame 121. The backrest 122 is slidably connected to the backrest frame 121 through the slide rail component 123.

[0075] The backrest 122 on this wheelchair can slide up and down relative to the backrest frame 121, decomposing the adhesion force to a certain extent, making the skin easier to leave the leather surface on the backrest 122. The user is more comfortable when using it, reducing the pain during bathing and having a better experience.

[0076] The backrest 122 at least includes a backrest mounting plate 124, the backrest mounting plate 124 is fixedly connected to the slide rail assembly 123, and a flexible or elastic backrest 125 is connected to the front side of the backrest mounting plate 124; since the backrest 125 is mainly made of a material similar to PU and cannot be directly fixed to the slide rail assembly 123, it is first connected to the backrest 122 through the backrest mounting plate 124, and then the backrest mounting plate 124 is fastened to the slide rail assembly 123 by screws.

[0077] In this embodiment, the slide rail assembly 123 includes a fixed slide rail 1231 and a moving slider 1232. The fixed slide rail 1231 is longitudinally fixed on the backrest frame 121, the moving slider 1232 is slidably connected to the fixed slide rail 1231, and the backrest mounting plate 124 is fixedly connected to the front side of the moving slider 1232; the fixed slide rail 1231 and the moving slider 1232 belong to a conventional sliding structure, with less friction, smooth sliding, quiet sliding, long service life, simple structure and convenient installation between them.

[0078] The backrest frame 121 includes a backrest outer frame 126. The slide rail assembly 123 is arranged within the hollow range of the backrest outer frame 126, and a backrest decorative plate 127 is assembled and connected to the rear side of the backrest outer frame 126. The backrest decorative plate 127 matches the shape of the backrest outer frame 126;

[0079] The backrest decorative plate 127 can block the slide rail assembly 123, so that the rear side of the wheelchair can be kept beautiful, and it can prevent foreign objects or the fingers of the caregiver from reaching into the slide rail assembly 123 during the sliding process, causing damage to the slide rail assembly 123 or injury to the caregiver; in addition, when the user takes a bath in the wheelchair, it can avoid or reduce water splashing onto the slide rail assembly 123, preventing the slide rail assembly 123 from rusting and affecting its service life.

[0080] The width of the backrest 122 is greater than the width of the backrest frame 121, and the left and right sides of the backrest 122 protrude equally from the left and right sides of the backrest frame 121 respectively; the height of the backrest 122 is greater than the height of the backrest frame 121, and mainly its upper part is higher than the upper side of the backrest frame 121; the backrest 122 that is larger than the backrest frame 121 as a whole can increase the area of support for the user's back, and it also helps to block the gap between the backrest 122 and the backrest frame 121, reducing the water splashing from the gap between the two onto the slide rail assembly 123.

[0081] In addition, the reason why mainly the upper part of the backrest 122 is higher than the upper side of the backrest frame 121 is that when the backrest assembly 12 of the wheelchair is flipped from the backrest state to the lying state, the backrest 122 will slide downward under the dragging of the user's back. Therefore, even after the backrest 122 slides downward, the upper part of the backrest 122 still has enough length to block the gap with the backrest frame 121 and maintain the waterproof effect.

[0082] A back waterproof motor 17 is movably hinged between the rear side of the seat frame 11 and the back frame assembly 12, and a leg waterproof motor 18 is movably hinged between the front side of the seat frame 11 and the footrest frame 14. The back frame assembly 12, the footrest bracket 13 and the footrest frame 14 are respectively driven by the back waterproof motor 17 and the leg waterproof motor 18 to flatten into a wheelchair bed relative to the seat frame 11. A waterproof battery box 19 and a waterproof electrical box 20 are further arranged in the seat frame 11, and the waterproof electrical box 20 is electrically connected to the waterproof battery box 19, the back waterproof motor 17 and the leg waterproof motor 18.

[0083] This electric wheelchair realizes the waterproof function as a whole through the waterproof electrical box 20, the waterproof battery box 19, the back waterproof motor 17 and the leg waterproof motor 18 with waterproof design. Users can directly take a shower on the wheelchair without having to convert it into a conventional single-function folding wheelchair before and after the shower, which is convenient for cleaning.

[0084] The electric wheelchair can be pushed into the bathroom for use and can realize various bathing methods for users. For example, the backrest can be lowered to facilitate washing the user's hair, and the user's legs can be lifted electrically for cleaning, so that the caregiver does not need to bend down. The electric wheelchair can also be stretched flat in the bathroom to form a wheelchair bed. When the user lies flat and takes a shower, the user can turn over up and down, and the cleaning is more thorough, which can improve the user's shower experience.

[0085] A sheet metal component is covered and connected to the seat frame 11. The sheet metal component encloses a semi-closed waterproof cavity D inside the seat frame 11.

An opening cover plate 33 is detachably connected to the defecation opening 3201. A backrest pad 43 is connected to the front side of the backrest frame assembly 12, and a leg bed board 44 of the foot support frame 13. This structure enables the user to defecate on the wheelchair. Only need to remove the opening cover plate 33 and urinate or defecate into the toilet pan 30 through the defecation opening 3201.

[0095] When the wheelchair A1 is flattened into a wheelchair bed A2, the lifting plate 2, the backrest pad 43, the seat board 32, the opening cover plate 33, the leg bed board 44 and the tail bed board 3 form the mattress of the other half of the nursing bed.

[0096] It further includes armrest frame assemblies 22 connected to the left and right sides of the seat frame 11. The armrest frame assemblies 22 include a fixed frame 221 and an armrest frame 222. The armrest frame 222 is flip-hinged in the outer space of the fixed frame 221. An elastic sliding lock tongue structure 223 is arranged on the armrest frame 222. One end of the lock tongue structure 223 is fixedly connected with a pull handle 224, and the other end extends out of or retracts into the armrest frame 222 following the movement of the pull handle 224. A lock hole 2221 corresponding to the lock tongue structure 223 is opened on the fixed frame 221. The lock tongue structure 223 is elastically inserted into the lock hole 2221 to lock the armrest frame 222 in the unfolded state.

[0097] The armrest frame 222 of this multifunctional wheelchair can be turned up and folded up and down. When switching from the storage state to the unfolded state, the armrest frame 222 turns from the outside to the inside, realizing a gradually clamping action, which can avoid the lower swing of the armrest frame 222 from hitting the user's body and causing injury.

[0098] Moreover, the armrest frame 222 is provided with a lock body. After unlocking, the armrest frame 222 can be turned down for storage, thus avoiding the occupation of space by the armrest frame 222 when not in use. When the wheelchair can be unfolded into a bed shape, the armrest frames are always located on the left and right sides of the cushion position and can be used as guardrails at the same time, with the best protection effect.

[0099] The lock tongue structure 223 includes a guide sleeve 2231, a pull rod 2232 and a spring 2233. The guide sleeve 2231 is fixed inside the armrest frame 222. The pull rod 2232 slides linearly in the guide sleeve 2231. The spring 2233 abuts between the guide sleeve 2231 and the pull rod 2232. One end of the pull rod 2232 is connected to the pull handle 224, and the other end elastically extends or retracts through the spring 2233.

[0100] The operating principle of the above structure:

[0101] When the armrest frame 222 is converted from the storage state to the unfolded state, at the elastic potential energy of the spring 2233, the other end of the pull rod 2232 will extend and insert into the lock hole 2221, thereby locking the unfolded state of the armrest frame 222. When the armrest frame 222 needs to be stored, the user only needs to pull the pull handle 224 upward, drive the pull rod 2232 to be pulled out of the lock hole 2221 and retract into the guide sleeve 2231. After unlocking the armrest frame 222, the armrest frame 222 is flipped again until it returns to the position in the storage state.

[0102] An anti-sway rod 2241 extends from the pull handle 224. The anti-sway rod 2241 is arranged on one side of the pull rod 2232 and is arranged at an interval before and after the pull rod 2232. A anti-sway hole 2222 that is slidably matched with the anti-sway rod 2241 is correspondingly opened on the armrest frame 222;

[0103] When the pull handle 224 is only connected to the fixed frame 221 by the pull rod 2232, it may cause the pull handle 224 to rotate axially around the pull rod 2232. Through the cooperation of the anti-sway rod 2241 and the anti-sway hole 2222, the pull handle 224 can be limited to the same position and play a certain guiding role.

[0104] A first limiting member is arranged on the fixed frame 221. When the armrest frame 222 is in the unfolded state, the inner side of the armrest frame 222 abuts against the first limiting member; in this embodiment, connecting plates 225 for hinging with the armrest frame 222 are arranged on both sides of the fixed frame 221. The first limiting member includes limiting blocks 2251 arranged on the outer sides of the two connecting plates 225, and the limiting blocks 2251 are located above the hinge shaft.

[0105] The fixing frame 221 is provided with a second limiting member, and when the armrest frame 222 is in the storage state, the outer side of the armrest frame 222 abuts against the second limiting member; the second limiting member includes a limiting shaft 2252 arranged on the outer sides of the two connecting plates 225, and the limiting shaft 2252 is located at the lower side of the hinge shaft.

[0106] The armrest frame 222 is provided with a grip 226, which extends in the same direction as the pull handle 224 and is disposed on the upper side of the pull handle 224. When the pull handle 224 is pressed against the grip 226, the other end of the pull rod 2232 is at least pulled out of the lock hole 2221.

[0107] When pulling the pull handle 224 to unlock, the user can first hold the grip 226 with one finger, and then use the remaining fingers to pull the pull handle 224 upward. This structure eliminates the need to lift the arm, and the pull handle 224 can be pulled by the palm alone, making it easier for the hand to exert force, and users with weaker physical strength can operate it by themselves; and the grip 226 plays a limiting role, preventing the pull handle 224 from being lifted excessively, thereby preventing the lock tongue structure 223 from being damaged by collision.

[0108] The pull handle 224 is in the shape of an umbrella handle, including a handle portion 224a and a handle bend 224b, and the handle portion 224a and the handle bend 224b are hidden in the vertical plane of the handrail frame 222; one end of the pull rod 2232 is connected to the handle portion 224a, and the handle bend 224b is placed on the upper side of the handle portion 224a as a grip and is spaced apart from the grip 226; this structure allows the user to hold the handle bend 224b when holding the grip 226, and the pull handle 224 is flush with the handrail frame 222, so that the handrail frame 222 remains compact and the pull handle 224 does not protrude.

[0109] The handrail frame 222 includes at least a pair of handrail vertical tubes 227, and a handrail curved tube 228 and a handrail horizontal tube 229 are respectively connected between the top and the middle part of the pair of handrail vertical tubes 227. The locking tongue structure 223 and the handle 224 are movably connected to the handrail horizontal tube 229. The handrail curved tube 228 is an "e"-shaped structure, and its tail is inclined and constitutes a handle 226.

[0110] The inclined grip 226 can adapt to the angle of the user's hand to improve comfort, and the handrail frame 222 composed of the handrail vertical pipe 227, the handrail horizontal pipe 229 and the handrail curved pipe 228 has a large protection area and good protection effect when used as a guardrail.

[0111] An armrest pad 45 is provided on the armrest curved pipe 228 ; the elastic armrest pad 45 can improve the comfort of the armrest frame 222 .

[0112] The pull rod 2232 includes a guide rod 2234, the outer end of which is connected to the pull handle 224, and the inner end of which is provided with a latch rod 2235. The top wall of the guide sleeve 2231 is provided with a guide hole 2236 that is linearly slidably matched with the guide rod 2234. The latch rod 2235 is linearly slidably matched with the guide sleeve 2231. The spring 2233 is sleeved outside the guide rod 2234 and abuts against the top wall of the guide sleeve 2231 and the latch rod 2235. The spring 2233 is built into the top of the guide sleeve 2231, so that the lock tongue structure 223 can be kept compact and small, and the spring 2233 can be limited and positioned.

[0113] A locking tube 34 is fixedly connected to the inner side of the bed frame B, and the locking tube 34 is arranged toward one side of the small bed foot frame 8; a limiting tube 35 is fixedly connected to the inner side of the small bed foot frame 8, and the limiting tube 35 is arranged toward one side of the bed frame B. When the small bed foot frame 8 is in the enclosed position, the limiting tube 35 and the locking tube 34 are abutted against each other; the cooperation between the limiting tube 35 and the locking tube 34 can limit the flipping position of the small bed foot frame 8 when enclosed, so that the movable end plate 92 and the fixed end plate 91 can be kept flat.

[0114] One of the bed frame B and the cot foot frame 8 is provided with a locking body, and the other of the bed frame B and the cot foot frame 8 is provided with a locking mating part, which is connected by the locking body and the locking mating part to lock the cot foot frame 8 in the enclosed position; the ability to buckle and lock can prevent the cot foot frame 8 and the movable end plate 92 from opening outwards when the cot foot frame 8 drives the movable end plate 92 under external force or without external force, thereby causing the bed to lose its protective structure.

[0115] Specifically, the lock fitting portion includes a locking opening 341 opened on the upper side of the locking tube 34; the lock body portion includes a hook 361, and the hook 361 is connected to the cot end frame 8 by swinging up and down. When the cot end frame 8 is in the enclosed position, the hook 361 is buckled in the locking opening 341.

[0116] The lock body also includes a swing rod 36, the middle part of which is rotatably connected to the end frame 8 of the cot, the hook 361 is arranged at the inner end of the swing rod 36 and faces downward, and a tension spring connecting plate 37 is provided on the lower side of the inner end of the swing rod 36, a tension spring 38 is connected between the tension spring connecting plate 37 and the end frame 8 of the cot, and a foot control pedal 39 is connected to the outer end of the swing rod 36, and the hook 361 is controlled by the foot control pedal 39 to swing elastically up and down.

[0117] In addition, the limit tube 35 is supported on the lower side of the inner end of the swing rod 36 to limit the downward swing range of the inner end of the swing rod 36. A limit lug 40 is provided on the lower side of the outer end of the swing rod 36 to limit the downward swing range of the outer end of the swing rod 36.

[0118] Based on the above structure, after the small bed end frame 8 drives the movable end plate 92 to flip to the enclosed position, the inner end of the swing rod 36 swings under the action of the tension spring 38, so that the hook 361 is buckled into the locking port 341 to lock the small bed end frame 8 in the enclosed position. When it is necessary to open the movable end plate 92, the caregiver steps on the foot control pedal 39 to make the inner end of the swing rod 36 swing upward, and the hook 361 leaves the locking port 341. Then the caregiver pulls the movable end plate 92, and the wheelchair docking recess C can be opened.

[0119] The lifting plate 2 is connected to the bed frame B through two groups of support brackets 41. The two groups of support brackets 41 are symmetrically connected to the left and right sides of the lifting plate 2; and a self-locking structure is provided on the support bracket 41. The two groups of support brackets 41 can stably support the lifting plate 2, and the self-locking structure can lock the flattened state of the lifting plate 2.

[0120] Specifically, any one group of support brackets 41 includes;

[0121] A fixed support rod 411, and the fixed support rod 411 is longitudinally fixed on the bed frame B;

[0122] A movable support rod 412, the lifting plate 2 is fixed on the outside of the movable support rod 412, and one end of the movable support rod 412 is rotatably hinged to the top end of the fixed support rod 411, and the other end is provided with a chute 4121 along the length direction;

[0123] Two connecting rods 413, one ends of the two connecting rods 413 are connected by a first hinge shaft 4131 and are rotatably hinged to the lower part of the fixed support rod 411, and the other ends of the two connecting rods 413 are connected by a second hinge shaft 4132 and are slidably connected to the chute 4121 through the second hinge shaft 4132.

[0124] When the above support bracket 41 is turned upward and flattened or downward and stored, the second hinge shaft 4132 can slide back and forth along the chute 4121, the sliding is smooth, the operation is simple, and the triangular structure is formed by using the connecting rod 413 to realize the support, and the support is stable and firm.

[0125] The length of the movable support rod 412 is greater than the length of the fixed support rod 411. The cross-sectional shapes of the fixed support rod 411 and the movable support rod 412 are both in a "U" shape structure, but the width of the movable support rod 412 is smaller than that of the fixed support rod 411. When the support bracket 41 is folded, the movable support rod 412 is embedded inside the fixed support rod 411, which can save space and make the lifting plate 2 fit closer to the bed end side. In addition, a notch 4122 for making way for the first hinge shaft 4131 is provided opposite to the movable support rod 412.

[0126] The self-locking structure includes a switch rocker 414 which is swingably connected below the chute 4121 through a rotating shaft 415. A torsion spring 416 is sleeved on the rotating shaft 415, and both ends of the torsion spring 416 act on the movable support rod 412 and the switch rocker 414.

[0127] Under the action of the torsion spring 416, the switch rocker 414 is inclined relative to the movable support rod 412, and its inner end is limited and abutted against the movable support rod 412 and forms an "X" shape with the chute 4121. When the lifting plate 2 is flattened, the second hinge shaft 4132 slides from the outer end of the chute 4121 to the inner end of the chute 4121. The second hinge shaft 4132 presses against the upper side of the switch rocker 414, thereby overcoming the action of the torsion spring 416 and smoothly sliding to the inner end of the chute 4121. The lifting plate 2 is in the flattened position and the switch rocker 414 is reset. After the lifting plate 2 bears weight, the second hinge shaft 4132 will be forced to slide from the inner end of the chute 4121 to the outer end of the chute 4121, but at this time the second hinge shaft 4132 will be stuck under the switch rocker 414, thereby preventing the second hinge shaft 4132 from moving forward. When the lifting plate 2 is manually flipped down, only need to hold the other end of the switch rocker 414 with both hands to make the switch rocker 414 return to a state parallel to the chute 4121, and the lifting plate 2 can be folded.
