[0022] Reference Figures 1 to 11 , a pension service assistance device, comprising a horizontal n-shaped rod 1, a vertical n-shaped rod 4, an inclined rod 5, a first roller 6, a second roller 601, a mounting plate 10, a protective plate 7, a protective door 701, a handle 7011, an armrest 3, a backrest 11, a seat plate 12, a toilet 13, a pedal 14, a reinforcing rod 9, an operating mechanism, a lifting mechanism, a first flipping mechanism, a second flipping mechanism, and a sliding mechanism; The lower parts of the front ends of the two vertical rods of the horizontal n-shaped rod 1 are respectively inclinedly installed with inclined rods 5, and the first rollers 6 are respectively rotatably installed on both sides of the lower ends of the two inclined rods 5; Protective plates 7 are respectively fixedly installed on the inner walls of the two inclined rods 5, and the same protective door 701 is movably installed between the two protective plates 7. The protective door 701 is detachably installed between the two protective plates 7 through a buckle. A handle 7011 is installed on the outer wall of the protective door 701. By opening the buckle, the protective door 701 can be flipped, which is convenient for the elderly to enter the device. After the elderly enter the device, closing the buckle can protect the elderly located inside the device on all sides; Armrests 3 are respectively movably installed behind the two vertical rods of the horizontal n-shaped rod 1. The two armrests 3 are respectively movably installed on the rear side of the cross bar of the horizontal n-shaped rod 1. The two armrests 3 are both driven to move by the operating mechanism. When the two armrests 3 are driven by the operating mechanism to protrude backward, the device will be in a wheelchair state, and the caregiver can hold the armrests 3 to push the device to move; A vertical n-shaped rod 4 is installed on the front wall of the cross bar of the horizontal n-shaped rod 1, and the upper ends of the two vertical rods of the vertical n-shaped rod 4 are fixedly installed on the front wall of the cross bar of the horizontal n-shaped rod 1; The front walls of the two vertical rods of the vertical n-shaped rod 4 are movably installed with the same backrest 11. The backrest 11 is driven to move by a lifting mechanism. The backrest 11 can slide up and down along the two vertical rods of the n-shaped rod 4 under the drive of the lifting mechanism. When the backrest 11 slides to the upper part, the device is in the state of a walking aid, and the backrest 11 will protect the front chest cavity of the elderly. When the backrest 11 slides to the lower part, the device is in the wheelchair state, and the backrest 11 can play a role in supporting the back of the elderly; The lower end of the cross rod of the vertical n-shaped rod 4 is fixedly installed with a mounting plate 10. The front wall of the mounting plate 10 is movably installed with a seat plate 12. The seat plate 12 is movably installed below the backrest 11. The seat plate 12 is driven to move by a first flipping mechanism. The seat plate 12 will flip up and down under the drive of the first flipping mechanism. When the seat plate 12 is flipped up, the elderly can sit on it. When the seat plate 12 is flipped down, the device is in the state of a walking aid, and the flipped-down seat plate 12 vacates the space inside the device, facilitating the elderly to walk inside; The lifting mechanism is driven to work by the first flipping mechanism; The first flipping mechanism is driven to work by the operating mechanism; The two inclined rods 5 and the front wall of the mounting plate 10 are respectively fixedly connected by a reinforcing rod 9 to solve the problem of strengthening the overall strength of the device. Second rollers 601 that cooperate with the first rollers 6 are respectively installed on the two side walls of the mounting plate 10. The diameter of the second rollers 601 is larger than that of the first rollers 6, which is convenient for moving the center of gravity of the device closer to the direction of the elderly and increasing the overall stability of the device; The mounting plate 10 is provided with a first rectangular through hole 1001. A toilet bucket 13 is slidably installed in the first rectangular through hole 1001. The first rectangular through hole 1001 defines the sliding track of the toilet bucket 13 and ensures that it will not fall off during the sliding process. The toilet bucket 13 is movably installed below the seat plate 12. The toilet bucket 13 is driven to slide by a sliding mechanism. When the device is in the wheelchair state, the seat plate 12 is parallel to the ground, and the toilet bucket 13 will just slide below the seat plate 12 under the drive of the sliding mechanism. When the circular cover plate 25 described later is flipped up, the needs of the elderly for using the toilet can be met; The sliding mechanism is driven to work by the first flipping mechanism; A pedal 14 is movably installed on the front side of the toilet bucket 13. The pedal 14 is movably installed below the seat plate 12. The pedal 14 is driven to move by a second flipping mechanism. The pedal 14 will flip down to be parallel to the ground synchronously when the seat plate 12 is flipped up to be parallel to the ground. The flipping up of the pedal 14 can ensure that it supports the feet of the elderly when the device is in the wheelchair state; The second flipping mechanism is driven to work by the first flipping mechanism.

[0023] The operating mechanism includes a movable n-shaped rod 2, a knob 18, and a threaded rod; On the rear walls of the two vertical rods of the horizontal n-shaped rod 1, there are respectively provided with second rectangular through holes 101, and the two vertical rods of the movable n-shaped rod 2 are respectively slidably installed in the two second rectangular through holes 101; The cross bar of the movable n-shaped rod 2 is movably installed at the rear side of the cross bar of the horizontal n-shaped rod 1; The first end of a threaded rod is rotatably installed on the rear wall of the middle part of the cross bar of the horizontal n-shaped rod 1, and the second end of the threaded rod threadedly penetrates through the middle part of the cross bar of the movable n-shaped rod 2 and is fixedly installed with a knob 18; The two handrails 3 are respectively obliquely and fixedly installed on the upper parts of the rear ends of the two vertical rods of the movable n-shaped rod 2; The movable n-shaped rod 2 drives the first flipping mechanism to work. By rotating the knob 18, the knob 18 starts to rotate and drives the threaded rod fixedly installed coaxially therewith to start rotating. The threaded rod can drive the movable n-shaped rod 2 penetrated by it to start sliding back and forth through rotation. Since the sliding trajectories of the two vertical rods of the movable n-shaped rod 2 are limited within the second rectangular through holes 101 that cooperate with them, the sliding trajectory of the movable n-shaped rod 2 is always in a horizontal moving state. As the n-shaped rod 2 slides back and forth in the horizontal direction, it can drive the two handrails 3 fixedly installed therewith to slide back and forth, and will simultaneously drive the first flipping mechanism described later.

[0024] The first flipping mechanism includes a first connecting rod 19 and a first L-shaped connecting rod 1201; The cross bars of the two first L-shaped connecting rods 1201 are respectively fixedly installed at the rear parts of the lower ends on both sides of the seat plate 12, and the cross bars of the two first L-shaped connecting rods 1201 are respectively rotatably installed on the outer sides of the two vertical rods of the vertical n-shaped rod 4 through first rotating shafts; The outer ends of the vertical rods of the two first L-shaped connecting rods 1201 are respectively fixedly installed with first connecting shafts, and the first ends of the first connecting rods 19 are respectively rotatably sleeved on the outer walls of the two first connecting shafts; On the outer walls of the two vertical rods of the horizontal n-shaped rod 1, there are respectively provided with first rectangular through slots 1011, and the two first rectangular through slots 1011 are respectively communicated with the second rectangular through holes 101 close to them; On the outer walls of the two vertical rods of the movable n-shaped rod 2, there are respectively fixedly installed second connecting shafts, and the two second connecting shafts respectively slide through the first rectangular through slots 1011 close to them; The second ends of the two first connecting rods 19 are respectively rotatably sleeved on the outer walls of the second connecting shafts close to them; The two first L-shaped connecting rods 1201 respectively drive the lifting mechanism to work through rotation; The seat plate 12 drives the sliding mechanism to work through rotation, refer to Figure 4, when the movable n-shaped rod 2 slides towards the right, when the right ends of the two first connecting rods 19 start to deflect forward, the left ends of the two first connecting rods 19 start to pull the first L-shaped rods 1201 close to them to start rotating clockwise upward along their own rotation centers. While the two first L-shaped rods 1201 rotate clockwise upward, the seat plate 12 fixedly installed between them starts to rotate clockwise downward and finally rotates to a state perpendicular to the ground. On the contrary, when the movable n-shaped rod 2 slides towards the left, the seat plate 12 starts to rotate counterclockwise upward and finally rotates to a state parallel to the ground.

[0025] The lifting mechanism includes a rectangular block 23, a T-shaped slider, and a second connecting rod 20; A rectangular block 23 is fixedly installed on the rear wall of the backrest 11, and vertical plates of the T-shaped slider are respectively fixedly installed at both ends of the rectangular block 23; T-shaped chutes 401 are respectively provided on the inner walls of the two vertical plates of the vertical n-shaped rod 4, and the horizontal plates of the two T-shaped sliders are respectively slidably installed in the T-shaped chutes 401 close to them; Third connecting shafts are respectively fixedly installed on both sides of the backrest 11, and the first ends of the second connecting rods 20 are respectively rotatably sleeved on the outer walls of the two third connecting shafts; The second ends of the two second connecting rods 20 are respectively rotatably sleeved on the outer walls of the first connecting shafts close to them; The two second connecting rods 20 are respectively movably installed inside the first connecting rods 19 close to them. Refer to Figure 4 , when the movable n-shaped rod 2 slides to the right, the seat plate 12 starts to flip downward, and the two first L-shaped connecting rods 1201 start to rotate upward. During the upward rotation of the vertical plates of the two first L-shaped connecting rods 1201, the lower ends of the two second connecting rods 20 will be driven to start rotating upward respectively. During the upward rotation of the lower ends of the two second connecting rods 20, their upper ends will start to deflect upward. At this time, the backrest 11 can be pushed to start sliding upward. At this time, the rectangular block 23 fixedly installed on the backrest 11 is limited by the cooperation of the T-shaped sliders on both sides and the T-shaped chutes 401, so the movement track of the backrest 11 is fixed. When the seat plate 12 flips downward to be perpendicular to the ground, the backrest 11 rises, and the internal space of the device becomes larger, and it can be changed to the state of a walking aid.

[0026] The sliding mechanism includes a rectangular sliding rod 22, a horizontal connecting rod 21, a rotating connection block 15, a guide rod 16, and a second L-shaped connecting rod 2201; Two third rectangular through holes 1002 are respectively provided on the mounting plate 10, and the two third rectangular through holes 1002 are respectively provided on both sides of the first rectangular through hole 1001; Two rectangular sliding rods 22 are respectively installed through the two third rectangular through holes 1002 in a sliding manner. A same horizontal connecting rod 21 is fixedly installed between the rear ends of the two rectangular sliding rods 22. The horizontal connecting rod 21 is movably installed at the rear side of the mounting plate 10; The bottom wall of the toilet 13 is detachably installed at the upper end of the horizontal connecting rod 21 through two screws; The front ends of the two rectangular sliding rods 22 are respectively fixedly installed with the horizontal plates of the second L-shaped connecting rods 2201; The two side walls of the pedal 14 are respectively rotatably installed on the inner walls of the vertical plates of the second L-shaped connecting rods 2201 close to them through the second rotating shafts; Rotating connecting blocks 15 are respectively rotatably installed at the front parts on both sides of the seat plate 12. Guide rods 16 are respectively installed through the two rotating connecting blocks 15 in a sliding manner; The lower ends of the two guide rods 16 are respectively fixedly installed at the upper parts of the joints between the horizontal plates and the vertical plates of the second L-shaped connecting rods 2201 close to them; The two second L-shaped connecting rods 2201 respectively drive the second flipping mechanism to work through sliding. Refer to Figure 4 , when the seat plate 12 rotates from bottom to top, it will respectively drive the two side rotating connecting blocks 15 to start moving upward. During the upward movement of the two rotating connecting blocks 15, they will respectively push the cooperating guide rods 16 to start sliding to the right. The second L-shaped connecting rods 2201 fixedly installed with the two guide rods 16 will drive the pedal 14 to start sliding out to the right at this time. During the process of the pedal 14 sliding out to the right, it will rotate from top to bottom to a state parallel to the ground under the drive of the following second flipping mechanism. At this time, the sliding trajectories of the rectangular sliding rods 22 fixed to the two second L-shaped connecting rods 2201 are respectively limited by the cooperating third rectangular through holes 1102. Therefore, they will not deviate during the sliding process. The horizontal connecting rod 21 fixedly installed between the rear ends of the two rectangular sliding rods 22 will also slide to the right along with the two rectangular sliding rods 22 at this time. The toilet 13 fixedly installed on the upper end of the horizontal connecting rod 21 through screws will also start to slide to the right at this time. When the seat plate 12 rotates from bottom to top to a state parallel to the ground, the toilet 13 can just slide through the first rectangular through hole 1001 to the lower side of the seat plate 12.

[0027] The second flipping mechanism includes spur gears 17 and rack plates 24; The two second rotating shafts respectively rotate through the vertical plates of the second L-shaped connecting rods 2201 close to them and are fixedly installed with spur gears 17; Rack plates 24 are respectively installed below the two spur gears 17; The two rack plates 24 are respectively fixedly installed on both sides of the lower end of the mounting plate 10 through connecting pieces; The two spur gears 17 are respectively meshed with the rack plates 24 close to them. Refer to Figure 9, when the pedal 14 slides to the right, it will drive the spur gears 17 on both sides to start sliding to the right. Since the rack plates 24 meshed with the two spur gears 17 are fixed, the two spur gears 17 start to rotate during the rightward sliding process. At this time, the pedal 14 coaxial with the two spur gears 17 can start to rotate clockwise from top to bottom and finally flip to a state parallel to the ground. At this time, the device is completely in the wheelchair state, the seat plate 12 flips up parallel to the ground, the pedal 14 flips down parallel to the ground, the backrest 11 descends close to the seat plate 12, the two armrests 3 extend outwards, and the toilet 13 is also located below the seat plate 12 at this time. Refer to Figure 8 , when the armrest 3 is pushed into the device to the right, the seat plate 12 flips down for storage, the pedal 14 flips up for storage, the toilet 13 slides out to the left, and the backrest 11 rises, and at this time the device can be changed to the walking aid state.

[0028] A flexible cushion 1101 is installed on the front wall of the backrest 11. Refer to Figure 8 , when the two armrests 3 slide to the extreme position towards the elderly, the backrest 11 is lifted upwards and placed in front of the chest of the elderly. The flexible cushion 1101 can provide a certain degree of protection for the chest of the elderly when the device is in the walking aid state, and can ensure a certain degree of comfort while supporting the back of the elderly when the device is in the wheelchair state.

[0029] A circular hole is provided on the seat plate 12, and a circular cover plate 25 is detachably installed in the circular hole. When the device is in the wheelchair state, since the toilet 13 is located below the seat plate 12, opening the circular cover plate 25 at this time can facilitate the elderly to use the toilet.

[0030] A flexible rod is fixedly installed on the upper part of the front end of the vertical rod of the horizontal n-shaped rod 1 near the left side. The other end of the flexible rod is rotatably installed with an elderly care service terminal 8. The elderly care service terminal can provide convenient services for the elderly when the device is in the wheelchair state, and has an alarm function and a call function, which is convenient for the nursing staff to monitor the status of the elderly in real time.

[0031] Implementation method of the present invention: When the device is in the wheelchair state, as Figure 11 shown in A, the two armrests 3 extend to the right respectively, the backrest 11 is located at the lower ends of the front walls of the two vertical rods of the vertical n-shaped rod 4 and close to the seat plate 12. At this time, the seat plate 12 is in the state of flipping up and parallel to the ground, and the toilet 13 is also exactly located below the seat plate 12. The pedal 14 flips down to be parallel to the ground and is placed in front of the toilet 13. At this time, the elderly can sit on the seat plate 12 with their backs against the backrest 11, and the nursing staff can hold the armrests 3 with both hands to push the device in the wheelchair state to move; When the elderly have the need to use the toilet, they only need to turn the circular cover plate 25 on the seat plate 12 upwards. After using the toilet, the elderly can call the caregiver through the elderly care service terminal 8; When the elderly need to perform walking training, they only need to turn the knob 18, and the movable n-shaped rod 2 starts to move towards the direction close to the elderly. When the two armrests 3 slide along with the movable n-shaped rod 2 to the direction close to the elderly, the seat plate 12 turns downwards and the pedal 14 turns upwards. It should be noted that the seat plate 12 and the pedal 14 will not collide and interfere during the turning process. When the seat plate 12 and the pedal 14 turn to be perpendicular to the ground, the toilet bowl 13 also slides out in the direction away from the elderly. At this time, the space inside the device becomes larger due to the retraction of the toilet bowl 13, the seat plate 12 and the pedal 14. At this time, the backrest 11 also lifts upwards and is located in front of the chest cavity of the elderly to provide a certain protective effect on the chest cavity of the elderly. At this time, the elderly can hold the two armrests 3 and move. The device acts as a walking aid at this time as Figure 11 shown in Figure B.

[0032] This device can lower or raise the seat plate and the pedal respectively under the simultaneous action of the first turning mechanism and the second turning mechanism. When the seat plate and the pedal are lowered simultaneously, the two armrests will protrude backwards at the same time, forming a wheelchair state, supporting the caregiver to push the device to carry the elderly to move. The toilet bowl in the device in the wheelchair state will also be located under the seat plate driven by the sliding mechanism. When the elderly need to use the toilet, they only need to turn up the circular cover plate. When the seat plate and the pedal are raised simultaneously, the device can be changed to the walking aid state, and the armrests will also approach the elderly in this state, facilitating the elderly to hold the armrests for walking exercise.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
