DETAILED DESCRIPTION

[0043] In order to make the contents of the present invention more clearly understood, the present invention is further described in detail below based on specific embodiments in conjunction with the accompanying drawings.

[0044] Embodiment 1:

[0045] See also Figures 1 to 7 As shown, this embodiment provides a toilet adjustment structure, including: a seat cushion and a toilet mechanism arranged below the seat cushion body 1; wherein the seat cushion includes a cushion body 1, a hollow opening 2 opened on the cushion body 1, and a filling pad 3 arranged below the cushion body 1 and suitable for being flipped over and filled into the hollow opening 2; the filling pad 3 is connected to a flip driving component suitable for driving it to flip.

[0046] The toilet mechanism includes a toilet bowl 4 suitable for being embedded in the hollow opening 2, a support frame 6 suitable for supporting the toilet bowl 4, and a movable frame 5 for carrying the support frame 6; a lifting and adjusting component is also provided between the support frame 6 and the movable frame 5; and the movable frame 5 is connected to the cushion body 1 through a translation drive component.

[0047] It should be noted that, for the hollow opening 2 on the cushion body 1, when the person sitting on the chair cushion needs to go to the toilet, the toilet bowl 4 is embedded in the hollow opening 2, and the filling pad 3 is folded 90 degrees relative to the cushion body 1 at this time; and when the person sitting on the chair cushion does not need to go to the toilet, the toilet bowl 4 will leave the hollow opening 2, and the filling pad 3 will be filled into the hollow opening 2, so that the filling pad 3 can achieve bottom support for the human body.

[0048] Specifically, in conjunction with the accompanying drawings, the translation drive assembly includes a screw 7 and a sleeve 8 threadedly connected, and a first power structure connected to the screw 7 and suitable for driving the screw 7 to rotate; the first power structure here can be a worm gear and worm reduction structure 9 used in conjunction. When the first power structure drives the screw 7 to rotate, the sleeve 8 is suitable for linear motion along the axial direction of the screw 7; and the first power structure is fixedly assembled on the mat body 1; and the sleeve 8 is connected to the mobile frame 5. It should be noted that the translation drive assembly designed in this embodiment is used to realize the horizontal movement of the mobile frame 5, so that the mobile frame 5 can drive the toilet bowl 4 to switch between moving toward the hollow opening 2 and moving away from the hollow opening 2.

[0049] The flip driving assembly includes a movable plate 10 supporting the filling pad 3, and a pair of flip execution structures with the same structure connected to the movable plate 10. Furthermore, the flip execution structure includes a support plate 11 fixedly connected to the pad body 1, a male connector 12 fixedly connected to the support plate 11, a female connector 13 rotatably matched with the male connector 12, a push plate 14 fixedly connected to the female connector 13, and a connecting plate 26 movably matched with one end of the push plate 14 away from the female connector 13; wherein the end of the connecting plate 26 away from the female connector 13 is hingedly connected to a support rod 16 fixed to the end face of the movable plate 10 away from the filling pad 3. It should be noted that the principle of the rotational matching between the male connector 12 and the female connector 13 of this embodiment is equivalent to that of a bearing. The flip driving assembly designed in this embodiment is used to realize the switching of the filling pad 3 to fill the hollow opening 2 and leave the hollow opening 2.

[0050] Considering the simplicity of the structure, a pair of flip execution structures are connected to the same second power structure; the second power structure includes a connecting rod 17 that runs through the female connector 13, the push plate 14 and the male connector 12 of the pair of flip execution structures, and a driving force structure connected to the connecting rod 17 to drive the connecting rod 17 to rotate; and the driving force structure includes a worm gear sleeved with the connecting rod 17, and a worm reducer 18 connected to the worm gear. The worm reducer 18 here can be fixed on the push plate 14 of one of the flip execution structures in the pair of flip execution structures by assembling with a connecting column.

[0051] More specifically, the side wall of the connecting rod 17 is evenly distributed with a number of convex teeth along its circumferential direction so that the radial cross section of the connecting rod 17 is toothed; and the connecting rod 17 is rotationally matched with the support plate 11. Such a structure avoids the need to match the gear on the general smooth connecting rod 17, so that the connecting rod 17 of this embodiment has directly matched the gear by using the convex teeth on its outer surface. Furthermore, since the male connecting member 12 is fixedly connected to the support plate 11, the connecting rod 17 and the male connecting frame are also in a rotationally matched relationship, and the connecting rod 17 and the female connecting member 13 and the push plate 14 are all in a fixed connection relationship. Under such a structure, that is, the worm reducer realizes the rotation of the connecting rod 17, and the connecting rod 17 drives the push plate 14 to rotate synchronously relative to the support plate 11, so that the push plate 14 can push the movable plate 10 to drive the filling pad 3, and the filling pad 3 can be turned over to realize the filling of the hollow opening 2 or leave the hollow opening 2.

[0052] In addition, the side edge of the support plate 11 facing away from the backrest cushion body 1 is an arc-shaped end face; and two limiting claws 21 are provided at intervals on the arc-shaped end face; a limiting column 22 vertically connected to the push plate 14 is integrally provided on the push plate 14; and the limiting column 22 is suitable for moving along the arc-shaped end face to achieve abutment with the two limiting claws 21. That is to say, the two states when the limiting column 22 abuts with the two limiting claws 21 correspond to the two states of the filling pad 3 filling the hollow opening 2 and leaving the hollow opening 2.

[0053] Furthermore, the lifting and adjusting assembly includes a transition rod 23 connected to a pair of connecting rods 17 correspondingly connected to the flip execution structure, a pair of V-shaped connecting frames 24 rotatably matched with the two ends of the transition rod 23, and a pair of X-shaped telescopic frames connected one by one to the pair of V-shaped connecting frames 24; wherein the transition rod 23 is connected to the connecting rod 17 through an L-shaped corner frame 25 in this embodiment.

[0054] The X-shaped telescopic frame includes a pair of connecting plates 26 connected by hinges; the two ends of the pair of connecting plates 26 facing the cushion body 1 are slidably matched with the support frame 6, and the two ends of the pair of connecting plates 26 away from the cushion body 1 are slidably matched with the moving frame 5; and the supporting frame 6 and the moving frame 5 are respectively provided with sliding grooves 27 slidably matched with the connecting plates 26, and the ends of the connecting plates 26 matched with the supporting frame 6 and the moving frame 5 can reciprocate horizontally along the sliding grooves 27; the V-shaped connecting frame 24 is rotatably connected with one end of the connecting plate 26 of the pair of connecting plates 26 away from the filling cushion 3 and matched with the moving frame 5. In this way, for the lifting and adjusting assembly of this embodiment, there is no need to set up additional power to realize its operation, but directly use the power when the movable plate 10 is turned over, that is, the turning execution structure is not only used to realize the turning of the movable plate 10, but also used to realize the operation of the above-mentioned lifting and adjusting assembly, which is not only conducive to simplifying the structure of the overall toilet adjustment structure, but also conducive to saving the overall production cost and maintenance cost.

[0055] Here, a connecting rod 28 may be provided between the V-shaped connecting frames 24 corresponding to a pair of flip execution structures. In this case, the connecting rod 28 only needs to realize sliding cooperation with the support frame 6, and the V-shaped connecting frame 24 is hingedly connected to the connecting rod 28. The lifting and lowering adjustment assembly designed in this embodiment is used to realize the lifting and lowering of the toilet bowl 4 placed on the support frame 6, so that the toilet bowl 4 can be lifted up to be embedded in the hollow opening 2 when using the toilet, and can be lowered after using the toilet to facilitate horizontal movement and leave the hollow opening 2 together with the moving frame 5, so as to make room for the filling pad 3 to fill the hollow opening 2.

[0056] On the basis of the above structure, it should be noted that in this embodiment, the bottom structure of the mobile frame 5 is matched with the X-shaped telescopic frame. The bottom structure can be the structure of the mobile frame 5 itself, or it can be a structure built into the mobile frame 5. This embodiment does not make an absolute limitation on this. Considering the limitation of the horizontal movement trajectory of the mobile frame 5, this embodiment also provides strip-shaped hollow grooves 29 on the two side end faces of the mobile frame 5 along its horizontal movement direction, and the two ends of the above-mentioned connecting rod 28 pass through the hollow grooves 29, and the connecting rod 28 can make horizontal reciprocating movements in the hollow grooves 29. In other words, the connecting rod 28 cooperates with the hollow grooves 29, and then cooperates with the translation drive assembly to jointly realize the horizontal movement trajectory of the mobile frame 5, and the mobile frame 5 in the state where the toilet 4 is not needed for going to the toilet is stably arranged under the pad body 1 together with the toilet 4, which plays a supporting role for the mobile frame 5.

[0057] In addition, in an optional implementation, taking into account the limitation of the deformation trajectory of a pair of connecting plates 26 when they are deformed, the deformation of the pair of connecting plates 26 can only realize the lifting and lowering movement of the support frame 6 relative to the mobile frame 5, and no horizontal movement will be generated. The present embodiment also has the following design: the hinge shaft 32 between the pair of connecting plates 26 is also slidably matched with a vertical plate 30 fixed on the mobile frame 5; and a movable groove 31 that is movably matched with the hinge shaft 32 is provided on the vertical plate 30; the groove length of the movable groove 31 is greater than the outer diameter of the hinge shaft 32.

[0058] In summary, for the toilet seat adjustment structure of this embodiment, there are two usage states:

[0059] The first state: not used as a toilet. In this state, the filling pad 3 is filled in the hollow opening 2; and the toilet bowl 4 is at the side position below the hollow opening 2.

[0060] The first state: toilet use. In this state, the filling pad 3 leaves the hollow opening 2 and is folded 90 degrees relative to the pad body 1.

[0061] During the switching process from the first state to the second state, the filling pad 3 is flipped relative to the pad body 1 to the bottom of the pad body 1 under the action of the movable plate 10. During the flipping process, the toilet bowl 4 is moved to the bottom of the hollow opening 2 under the action of the moving frame 5, and the toilet bowl 4 rises under the action of the X-shaped telescopic frame so that the toilet bowl 4 is embedded in the hollow opening 2; after using the toilet, the toilet bowl 4 is lowered under the action of the X-shaped telescopic frame so that the toilet bowl 4 moves to the bottom of the hollow opening 2, so that the toilet bowl 4 leaves the hollow opening 2 with the support frame 6 under the action of the moving frame 5. In addition, during the process of the toilet bowl 4 leaving the hollow opening 2, the filling pad 3 is synchronously flipped upward to the hollow opening 2 to gradually fill the hollow opening 2 and return to the first state.

[0062] Embodiment 2:

[0063] Based on the toilet seat adjustment structure of Example 1, this embodiment provides a nursing chair, including: the toilet seat adjustment structure of Example 1.

[0064] In addition, the nursing chair of this embodiment further includes a support base 34 disposed below the toilet mechanism, and an X-shaped telescopic plate disposed between the support base 34 and the cushion body 1; and the X-shaped telescopic plate includes a pair of support plates 33 connected in hinged connection; one end of one support plate 33 of the pair of support plates 33 is hingedly connected to the cushion body 1, and the other end is slidably matched with the support base 34; and one end of the other support plate 33 of the pair of support plates 33 is hingedly connected to the support base 34, and the other end is slidably matched with the cushion body 1. Here, a strip-shaped notch 40 matching with the support plate 33 is disposed on the support base 34 and the cushion body.

[0065] That is to say, the cushion body 1 can be lifted and lowered relative to the support base 34 by deformation of a pair of support plates 33, so that the nursing chair of this embodiment can adjust its support height relative to the ground according to the height requirements of different user groups.

[0066] For the above-mentioned power for deforming the support plates 33, the present embodiment adopts a connecting column 35 connected to one of the support plates 33, a screw rod 36 threadedly connected to the connecting column 35, and a drive wheel suitable for driving the screw rod 36 to rotate, and the drive wheel is connected to a worm reducer for driving the rotation of the driver. When the screw rod 36 rotates, the connecting column 35 can make a reciprocating motion along the axial direction of the screw rod 36 to realize the lifting and lowering motion of a pair of support plates 33. The worm reducer is fixedly connected to one of the support plates 33, and the support plate 33 is not provided with a connecting column 35, that is, the connecting column 35 and the worm reducer 37 are respectively fixed to one of the support plates 33.
