DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 As shown, a toilet assisting device comprises a supporting mechanism 1, a power mechanism 2 and an armrest mechanism 3. The power mechanism 2 is arranged on the supporting mechanism 1, and the armrest mechanism 3 is arranged on the supporting mechanism 1 and connected with the power mechanism 2. The function of the armrest mechanism 3 is to press against the armpits of the elderly to facilitate the conduction of force. The power mechanism 2 drives the armrest mechanism 3 to change the angle, driving the elderly who press against the armpits to stand up, thereby achieving the effect of assisting the elderly to stand up when using the toilet.

[0027] like Figure 1-Figure 6As shown, the support mechanism 1 includes a footrest 11, a knee guard bar 12, a leg support 13 and a connecting rod 14. The footrest 11 is horizontally arranged, and a universal wheel is installed at each of the four corners of the bottom of the footrest 11. The footrest 11 is used for the elderly to step on. Two knee guard bars 12 are fixedly connected to one side of the footrest 11. The two knee guard bars 12 are symmetrically distributed with the center line of the footrest 11 as the axis. The leg side of the two knee guard bars 12 is fixedly connected with the leg support 13. A connecting rod 14 is fixedly connected between the two knee guard bars 12. The footrest 11 and the knee guard bar 12 are designed in an integrated manner to facilitate assembly and increase stability and reliability. The surface of the footrest 11 is made of frosted material to prevent the elderly from slipping during use and causing danger. The knee guard bar 12 is The horn-shaped rod is designed according to the human standing theory. The leg rest 13 is made of soft material and can fix the knees and legs of the elderly through straps, while protecting the knees and legs of the elderly from injury during standing. The power mechanism 2 includes a hydraulic cylinder 21. The end of the hydraulic cylinder 21 close to the foot pedal 11 is hinged to the side of the foot pedal 11 through a rod. The armrest mechanism 3 includes a middle cover 31 and an armrest frame 32. The side of the middle cover 31 facing the hydraulic cylinder 21 is fixedly connected to the output end of the hydraulic cylinder 21, and the output end of the hydraulic cylinder 21 is inserted into the hole groove of the middle cover 31 and fixed. The side of the middle cover 31 facing the foot pedal 11 is fixedly connected with the armrest frame 32. The middle cover 31 and the armrest frame 32 adopt an integrated design, and the two rotating rods 4 are symmetrically distributed with the center line of the foot pedal 11 as the axis.

[0028] In the specific implementation process, firstly, the self-locking of the universal wheel is opened before use, and the device is pushed in front of the elderly user who is using the toilet. The elderly user's feet are placed on the foot pedal 11, and the knees and leg rests 13 are fastened and fixed by elastic straps, and the universal wheel is locked. At this time, the elderly user sits on the toilet and leans forward on the armrest 32, so that the horn-shaped protrusion of the armrest 32 presses against the elderly user's armpit from behind, which facilitates the transmission of the device's force. After it is fixed, the hydraulic cylinder 21 can be started, so that the hydraulic cylinder The armrest 32 and the middle cover 31 extend upward and lift up the middle cover 31. Due to the fixing effect of the rotating rod 4, the armrest 32 and the middle cover 31 will make a circular motion around the connection between the rotating rod 4 and the knee guard bar 12, thereby changing the inclination angle of the armrest 32 and the middle cover 31 to increase the horizontal height of the armrest 32, providing a force for the elderly toilet user to be pulled up from a sitting state to a prone standing state. Because the knee is tied to the knee guard bar 12 and the footrest 11 with an elastic band, the thigh is equivalent to a body that can be moved around. The knee-rotating rod, under the action of the force generated by the position change of the armrest frame 32 and the middle cover 31, the thigh of the elderly person rotates clockwise around the knee, so that the elderly person sitting on the toilet lies prone on the device and is slowly lifted to a nearly standing state by the device. At this time, the elderly person lies prone on the device with his legs nearly upright, and the nursing staff can easily perform relevant nursing work on the user who has finished using the toilet. After the nursing work is completed, the universal wheel locking switch can be turned on, the elderly person can be pushed to the edge of the bed, the universal wheel can be locked, the hydraulic cylinder 21 can be started, the hydraulic cylinder 21 can be contracted, and the armrest frame 32 and the middle cover 31 can make counterclockwise circular motion around the connection between the rotating rod 4 and the knee guard bar 12, until the thigh is bent to such an extent that the user's buttocks are completely in contact with the bed, the elderly person's upper body is straightened, the hydraulic cylinder 21 is closed, the elastic fixing strap at the knee guard bar 12 is loosened, the universal wheel locking switch is turned on, the elderly person's feet are placed on the ground from the foot pedal 11, and the device is pushed away, so as to realize the function of assisting the user to use the toilet.

[0029] like Figure 7 and Figure 8 As shown, the theoretical basis for the operation of the device is provided. Figure 7 The middle arrow indicates the movement direction of the handrail 32. The first component 5 and the second component 6 slide relative to each other through the movable pair at B, causing the second component 6 to slide upward. Furthermore, the second component 6 causes the third component 7 to rotate around the rotating pair at D through the rotating pair C at the third component 7. In the figure, the movable component is the third component 7, the rotating pairs are at three locations ACD, and the movable pair is at one location B, i.e., there are 4 low pairs in total. The degree of freedom of the mechanism is calculated, and it is found that F=3x3-4x2=1, proving that the movement of the mechanism is feasible.

[0030] Working process: first, open the self-locking of the universal wheel before use, push the device in front of the elderly user who is using the toilet, put the elderly user's feet on the foot pedal 11, tie the knees and leg rest 13 with elastic straps, lock the universal wheel, make the horn-shaped protrusions of the handrail frame 32 press against the elderly user's armpits from behind, start the hydraulic cylinder 21, make the hydraulic cylinder 21 extend and move upward, lift the middle cover 31, increase the horizontal height of the handrail frame 32, and make the elderly sitting on the toilet lie prone on the device and be slowly lifted to a nearly standing state by the device.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
