In order to fully disclose the present utility model to those skilled in the art, the technical solutions in the embodiments of the present utility model will be described in detail below with reference to the accompanying drawings in the embodiments of the present utility model.

The nursing support disclosed by the disclosure can be divided into a fixed type and a movable type, wherein the fixed type refers to that a rack of the nursing support is fixedly arranged on a wall or the ground or other reliable objects when the nursing support is used, and the movable type refers to that a supporting leg 108 is arranged on the rack of the nursing support, so that the nursing support can realize self-balancing and movable use without depending on other objects when the nursing support is used normally.

For ease of understanding and description, the directional relation of the present utility model is set as: when a user sits on the nursing support, the direction faced by the user is the front of the nursing support, the direction of the top of the head of the user is the upper side of the nursing support, the use environment is set to be used in combination with a toilet with more severe requirements on the nursing support, and the nursing support capable of being used in combination with the toilet is also applicable to the environment without the toilet.

As shown in fig. 1, 8 and 9, the present embodiment exemplarily shows a posture-changing nursing support, the nursing support is a space link mechanism, and comprises a support system 1, a roller shutter system 2, a power system 3 and a control system, the support system 1 comprises a swinging frame 103 and a first support 101 for providing a fulcrum for swinging of the swinging frame 103, the swinging frame 103 comprises a swinging arm and a swinging rod 1033, the roller shutter system 2 comprises a reel 201 and a curtain 202, two ends of the curtain 202 are respectively fixed on the reel 201 and the swinging rod 1033, the reel 201 is in transmission connection with the power system 3, the reel 201 is installed at the upper part of the support system 1, the swinging rod 1033 swings along with the swinging frame 103 under the driving of the power system 3, the rotation of the reel 201 can be independently completed or the retraction and the arrangement of the curtain 202 can be completed in coordination with the lifting of the swinging rod 1033, and the curtain 202 synchronously presents a state suitable for including sitting preparation, sitting and squatting and posture change between the states, thereby assisting a user in realizing posture change including sitting and squatting and sitting; specifically, the power system 3 is controlled by the control system, under the driving of the power system 3, the "soft" retraction (winding and releasing) of the curtain fabric 202 and the "hard" lifting swing of the swing rod 1033 are matched, the curtain fabric 202 presents states and transitions between states as shown in fig. 4, 5, 6 and 7 (fig. 4, 5, 6 and 7 are working states of the embodiment shown in fig. 1 of the present utility model, and compared with other nursing brackets covered by the technology of the present disclosure including other embodiments of the present disclosure, differences exist in structure, but they all have the same necessary technical characteristics, so description is used), and the transitions between the corresponding states can achieve corresponding body position changes, specifically including:

The curtain cloth 202 shown in fig. 4 is wound up, and the nursing bracket is folded;

turning to FIG. 4, turning the curtain 202 as shown in FIG. 5 to an inclined support surface, suitable for "sitting preparation";

turning the inclined support surface of the curtain cloth 202 shown in fig. 6 to an L-shaped surface, the curtain cloth is suitable for turning a station into a seat;

on the contrary, in fig. 6 to fig. 5, the 'L' surface is changed into an inclined pushing surface, so that the device is suitable for being changed into a standing position;

the "L" surface, as shown in FIG. 6, is suitable for "sitting";

the L-shaped surface is changed into a V-shaped surface as shown in the mode of changing from FIG. 6 to FIG. 7, and the device is suitable for changing from sitting to squatting;

on the contrary, in fig. 7 to fig. 6, the V-shaped surface is changed into an L-shaped surface, and the V-shaped surface is suitable for being changed from a squat posture to a sitting posture;

the inclined supporting surface shown in fig. 5 is changed into a rolling surface, and the nursing bracket is folded;

because the 'depending' means that the body of the user depends on the curtain cloth 202 when the user uses the nursing support to stand, sit or squat or in the standing, sitting or squat conversion process, the 'depending' can increase the safety and comfort experience of the user using the nursing support and is usually accompanied with the whole use process, and therefore, the description will not be repeated here below;

the connection rod structure and the matching of 'soft' and 'hard' enable the nursing bracket to achieve better folding (folding and unfolding) and operation effects, and of course, the conflict is avoided in the aspects of arrangement of each component or part of the nursing bracket, operation of the mechanism and between the nursing bracket and the use environment according to the use requirement, the arrangement comprises the number, the shape and the size of the component or part and the connection (comprising the connection mode and the connection position) between the component or part, and on the basis, the nursing bracket can be optimized or changed; in this regard, specific examples are set forth below;

As can be seen from the above description about the state of the nursing rack during operation and the mutual transition between the states, the reel 201 is mounted on the upper part of the rack system 1, specifically on the top of the first rack 101 as shown in fig. 1, so that, on one hand, when the rack system 1 is unfolded, the reel 201 is positioned obliquely above the swinging rod 1033, and the curtain 202 which is unfolded in a staggered manner is like an angle-adjustable reclining chair, which is beneficial to the bearing of the curtain 202 on the body of a user during operation of the nursing rack, on the other hand, the first rack 101 is hinged with the swinging frame 103, the hinging rotation of the first rack 101 is controlled by the power system 3, and the rotation of the reel 201 is also controlled by the power system 3, so that the state of the curtain 202 is controllable, such as the reel 201 is mounted on the top of the second U-shaped rack 102 as shown in fig. 1, and the state of the curtain 202 is out of control by the power system 3 (see the "nursing rack two" section hereinafter), and then the state of the nursing rack is disturbed;

on the contrary, if the positions of the reel 201 and the swing link 1033 are interchanged, that is, the reel 201 is mounted on the swing link 1033, the pull rod is additionally disposed at the position of the original reel 201 for fixing the other end of the curtain 202, and although the above two advantages are still present, the use experience of the user is obviously different, because: in the "sitting-turning station", the reel 201 winds the curtain cloth 202, and the user sitting on the curtain cloth 202 moves the buttocks forward along with the curtain cloth 202 due to the existence of friction force, and the phenomenon that the user moves out of the bearing surface of the curtain cloth 202 without standing the buttocks can occur, so that the risk of sliding down of the user exists; meanwhile, when the user stands and sits, the user can move backwards along with the curtain cloth 202 due to the existence of friction force; in addition, the skin, meat and clothes have potential safety hazards involved by the reel 201, and naturally, in order to eliminate the potential hazards, the curtain 202 can be solved by bypassing the swing rod 1033 (a roller is additionally arranged on the swing rod 1033) and displacing the reel 201 backwards, but in this way, on one hand, the structure becomes complicated, on the other hand, the occupation of the reel 201 and a driving device of the reel can be obviously increased, and when in use, the curtain is easy to collide with adjacent components or surrounding environments; therefore, this approach should be used carefully, except as needed;

In order to adapt to different use requirements, under the condition of no conflict, the utility model can be combined with other technical characteristics capable of enriching the use experience of the utility model, wherein the technical characteristics comprise that the curtain cloth 202 is provided with functional holes and/or additional functional modules, the armrests 106 are arranged, the mounting support legs 108 realize the movable use of the nursing support, the outside of the scroll 201 is provided with a protective shell 203 for preventing foreign matters from being involved in;

in order to adapt to different use requirements, under the condition that the scope of the right protection of the utility model is not exceeded and the technical characteristics of the utility model are not conflicted, the utility model can be optimized, changed or replaced, such as the swing frame 103 shown in fig. 1 and 8, when the nursing support is only used for rehabilitation training with posture change, the swing frame 103 can be changed into a 'T' -type or a common 'vegetable shovel' -type (the big end of the 'T' -type or the 'vegetable shovel') and correspondingly, a power device for driving the swing frame 103 needs to be adjusted (taking fig. 1 as an example, only one electric push rod 301 is in transmission connection with the tail part of the swing frame 103 in the middle position of the nursing support), and the optimization or the change can simplify the structure of the nursing support and reduce the cost; for example, the power system 3 shown in fig. 1 and 8 comprises an electric push rod 301 and a motor 302, the electric push rod 301 drives the swing frame 103 to reciprocate, the motor 302 drives the scroll 201 to rotate, and the power device suitable for driving the swing frame 103 to reciprocate and driving the scroll 201 to rotate comprises various transmission devices, which can be used for constructing the power system 3 of the utility model;

Not only the swing frame 103 and the power system 3 are different in construction (optimization, variation or replacement) modes, but also the subsystems can be configured according to the use requirement, and the configuration is also various, so long as the state and the transition of the curtain cloth 202 in the embodiment can be coordinated and realized by the aid of the reel 201 and the swing rod 1033, and the conflict is avoided, the position change can be realized by assisting a user, the problems in the prior art can be solved, and the beneficial effects of the utility model are achieved.

Obviously, the utility model has the characteristics of complete functions and outstanding folding and unfolding effects;

the manner in which the nursing support subsystem is constructed or the configuration of the subsystem will be further described below.

Preferably, the swing frame 103 and the first bracket 101 are both U-shaped, the swing arm includes a first swing arm 1031 and a second swing arm 1032, the swing arm 1033 is fixedly connected to the head ends of the first swing arm 1031 and the second swing arm 1032, the first bracket 101 includes the first support arm 1011, the second support arm 1012 and a third support arm 1013 fixedly connected therebetween, and the first swing arm 1031 and the second swing arm 1032 are respectively hinged with the first support arm 1011 and the second support arm 1012;

Specifically, as shown in fig. 8, the first swing arm 1031 and the second swing arm 1032 are respectively hinged to the first support arm 1011 and the second support arm 1012, so as to provide a fulcrum for the swing of the swing frame 103, and the swing rod 1033 is driven by the power system 3 to swing up and down along with the swing frame 103;

one of the application occasions of the utility model is to be used in combination with a toilet, so that the nursing bracket cannot conflict with the toilet, including normal use of the toilet is not affected, and the application of the U-shaped bracket in the bracket system 1 is just for this purpose, for example, the arrangement of the swing frame 103 is required to meet the requirements of not conflicting with the nursing bracket when in folding and unfolding and not conflicting with the toilet when in combination with the toilet; specific: in order to avoid the collision between the swing frame 103 and the nursing support, the height of the swing rod 1033 should be lower than the height of the scroll 201 when the swing frame 103 swings to the vertical state; in order to avoid collision between the swinging frame 103 and the toilet, the swinging frame 103 is made into a U shape that only the head ends of the first swinging arm 1031 and the second swinging arm 1032 are provided with the swinging rod 1033, the inner diameter size of the swinging frame 103 is larger than the outer diameters of the seat ring and the cover plate of the toilet, and when the swinging frame 103 swings to the vertical state, the height of the swinging rod 1033 is not lower than the height of the seat ring and the cover plate of the toilet after being vertical, so that the normal use of the seat ring and the cover plate of the toilet is not influenced by the swinging frame 103;

Obviously, if the nursing bracket is only used in an unobstructed environment, the strength of the swing frame 103 can be fully enhanced by adding a connecting rod between two swing arms of the U-shaped swing frame 103, so that the stability of the nursing bracket is improved; in addition, the "U" shape is only for convenience of description and understanding, the "U" shape should not be imagined to be a certain fixed shape, for example, the shapes of the U-shaped swing frame 103 and the first bracket 101 shown in fig. 1 and fig. 8 are different, the first swing arm 1031 and the second swing arm 1032 of the U-shaped swing frame 103 are bent at the hinge positions of the first support arm 1011 and the second support arm 1012, the optimization becomes better, as shown in fig. 4, the phenomenon that the clamping phenomenon occurs due to too small transmission angle between the tail part of the swing arm of the swing frame 103 and the output end of the electric push rod 301 can be avoided, and meanwhile, the action of moving forward and backward when the swing arm 1033 in the first bracket and the second bracket performs lifting swing (which will be described in the following "sitting" embodiment) is also achieved by cooperating with the linkage of the bracket, the first bracket 101 does not need to be imitated according to the bending;

preferably, in order to enable the user to obtain more comprehensive use experience, the cord fabric 202 is provided with functional holes and/or additional functional modules according to use requirements;

Specifically, the functional holes comprise holes which are convenient for defecation and sanitary cleaning as shown in fig. 1, and the additional functional modules comprise modules with functions of supporting, covering, collecting excrement, heating, sterilizing, ventilating, cleaning, assisting physical examination and treatment, monitoring physical signs and the like, and the additional modes can be fixed or detachable;

the support module supplements the additional support of the curtain cloth 202, and focuses on the support of the section of the seat (the sitting position of the user during use), so that the curtain cloth 202 can be kept flat and shaped, the applicability of products can be improved, and particularly, under the condition that the curtain cloth 202 lacks similar toilet seat support, the support module which has basically the same function as the toilet seat can be added to the section of the seat of the curtain cloth 202; the covering module is used for shielding the functional holes on the curtain cloth 202, so that the curtain cloth 202 can be freely switched between the functional holes and the nonfunctional holes, and one machine is multipurpose; of course, the present utility model can also meet different usage requirements by replacing the curtain cloth 202 or configuring different curtain cloth 202.

For normal use and folding of the nursing support, the additional function module cannot affect the bending between the "seat section" and the "backrest section" of the curtain 202 and between the "seat section" and the swing link 1033, and when the additional function module is not suitable for being wound by the reel 201, the solution may be: 1. the functional module is detachable and is detached when not in use; 2. the method of mating the spool 201 with the rocker 1033 can be employed without affecting the windable "back section" curtain, and for ease of description and understanding, specific embodiments are described below in relation to examples of methods of use of the nursing support.

Preferably, the power system 3 comprises an electric push rod 301 and a motor 302, the electric push rod 301 is in transmission connection with the swing frame 103, the swing frame 103 is driven to do reciprocating lifting swing, the swing rod 1033 is in lifting swing along with the swing of the swing frame 103, the motor 302 is in transmission connection with the scroll 201, and preferably, the motor 302 is in tooth transmission connection with the scroll 201;

because the market selectivity of the electric push rod 301 and the motor 302 is high, the electric push rod is beneficial to enriching products and controlling cost; specifically, as shown in fig. 8, the middle parts of the first support arm 1011 and the second support arm 1012 are respectively hinged with the middle parts of the first swing arm 1031 and the second swing arm 1032, the output ends of the two electric push rods 301 are respectively hinged with the tail ends of the first swing arm 1031 and the second swing arm 1032, the tail parts of the two electric push rods 301 are respectively hinged with the first support arm 1011 and the second support arm 1012, and the scroll 201 is in tooth transmission connection with the motor 302 and is arranged at the top of the first bracket 101;

in use, the first bracket 101 is used as a mounting frame to mount the care support on a wall or floor or other reliable object, and the method of use is described in detail below;

the present embodiment shows one of the basic architectures of the nursing support, and for convenience of description, the nursing support is referred to as a nursing support one;

Obviously, according to the lever principle, the swing fulcrum of the swing frame 103 and the access point of the output end of the electric push rod 301 of the present embodiment are changed, so that an equivalent alternative scheme of the above technical scheme can be obtained: the tail ends of the first swing arm 1031 and the second swing arm 1032 are respectively hinged to the middle parts of the first support arm 1011 and the second support arm 1012, and the output ends of the two electric push rods 301 are respectively hinged to the middle parts of the first swing arm 1031 and the second swing arm 1032.

Preferably, on a "first care stand" basis, the stand system 1 further comprises a second U-shaped stand 102, a connecting plate 104 and a folding bar 105; the second U-shaped bracket 102 includes a fourth arm 1021, a fifth arm 1022, and a sixth arm 1023 fixedly coupled therebetween; the first arm 1011 and the fourth arm 1021 and the second arm 1012 and the fifth arm 1022 are respectively hinged with the head end and the tail end of the two connecting plates 104, the tail ends of the two folding rods 105 are respectively hinged with the fourth arm 1021 and the fifth arm 1022 or are slidably connected with the tail ends of the first arm 1031 and the second arm 1032, the bottom ends of the first arm 1011 and the second arm 1012 are respectively hinged with the pulleys 1014, and the tail ends of the two electric push rods 301 are respectively hinged with the first arm 1011 and the second arm 1012 or respectively hinged with the fourth arm 1021 and the fifth arm 1022;

Specifically, as shown in fig. 1, the tail parts of the two electric push rods 301 are respectively hinged with a fourth support arm 1021 and a fifth support arm 1022, and the tail ends of the two folding rods 105 are respectively hinged with the fourth support arm 1021 and the fifth support arm 1022;

the tail end of the folding bar 105 is slidably connected to the fourth arm 1021 and the fifth arm 1022, respectively, in the following manner: the fourth arm 1021 and the fifth arm 1022 are provided with guide rails, the guide rails are provided with sliding blocks, the guide rails are in sliding connection with the sliding blocks, the tail parts of the first swing arm 1031 and the second swing arm 1032 are hinged with the two sliding blocks through two folding rods 105 (the folding rods 105 are equivalent to connecting parts and are preferably connected at a short distance at the moment), and preferably, the tail ends of the folding rods 105 are fixedly connected with the sliding blocks; obviously, according to the lever principle, this embodiment can be modified as follows: the swinging pivot of the swinging frame 103 is moved from the first bracket 101 to the second U-shaped bracket 102 (i.e. the tail parts of the first swinging arm 1031 and the second swinging arm 1032 are respectively hinged with the fourth supporting arm 1021 and the fifth supporting arm 1022), the sliding pairs on the fourth supporting arm 1021 and the fifth supporting arm 1022 are moved to the first supporting arm 1011 and the second supporting arm 1012, the middle parts of the first swinging arm 1031 and the second swinging arm 1032 and the output ends of the two electric push rods 301 are respectively connected with the two sliding blocks (the folding rod 105 is equivalent to a common connecting part at this time), the rest is unchanged, and the changed scheme still can solve the technical problems basically the same as the embodiment and obtain basically the same technical effects;
