One end of the limiting rod is connected with the first supporting rod, and the other end of the limiting rod is connected with the third supporting rod. The top surfaces of the first connecting rod and the second connecting rod are provided with arc-shaped grooves.

Fig. 2 is a schematic view of an armrest mechanism according to an embodiment of the invention. Fig. 3 is a sectional view a-a of an armrest mechanism according to an embodiment of the present invention.

As shown in fig. 2 to 3, the armrest mechanism 2 in the present embodiment includes: bracket 201, lead screw 202, push rod 203 and handrail 204. The square of the bracket 201 is a hollow cylinder, and the inner side surface of the bracket 201 is provided with a positioning groove parallel to the axis. The bottom end of the bracket 201 is provided with a plurality of mounting holes, and the connecting bolts penetrate through the mounting holes to be connected with the base. The push rod 203 is cylindrical, the outer side surface of the push rod is provided with a positioning block, the shape of the push rod is matched with the positioning groove, and the positioning block is arranged in the positioning groove, so that the push rod 203 is connected with the support 201 in a sliding mode. The top surface of the push rod 203 is provided with a hole. The push rod 203 has a threaded hole extending from the bottom surface to the top surface thereof. The lower part of the screw rod 202 is arranged on the base, and the upper part is in threaded connection with the bracket 201. The armrest 204 is mounted on the top end of the push rod 203 by means of fixing bolts.

Two universal wheels 4 are respectively installed on the installation of first mounting panel front end and the mount pad of second mounting panel front end.

Two driving wheels 5 are respectively installed on the installation seat at the rear end of the first installation plate and the installation seat at the rear end of the second installation plate. Wherein the driving wheel 5 is a wheel driven by a motor in the pulley, thereby realizing the movement and the rest of the seat 1.

A pair of rotating electric machines 7 are installed on the top surfaces of the first and second connecting rods, respectively. All install slide 6 in the pivot of rotating electrical machines 7, have the arc piece in the bottom surface of slide 6, the arc piece is installed in the arc wall, makes slide 6 and seat 1 sliding connection. Wherein, the slide 6 is used for providing a seat for a user when being combined, and a backrest is installed at the top ends of the second connecting rod and the fourth connecting rod to prevent the user from accidents.

The drive device 3 includes: the storage battery, the switch, the plurality of wires and the direct current motor are electrically connected through the plurality of wires. The storage battery is arranged on the backrest, the direct current motor is arranged on the base, and the screw rod 202 is driven to rotate in a belt transmission mode.

A toilet assisted standing wheelchair further comprising: the detector includes a timer and a vibration motor. The alarm is a buzzer. The timer, the vibration motor and the buzzer are respectively electrically connected with the controller. The toilet time of the old is counted by a timer, when the time reaches a preset value, the vibration motor and the buzzer work simultaneously to remind the old whether time delay is needed, if time delay is needed, a cancel button is pressed, and at the moment, the vibration motor and the buzzer stop working; if the button is not cancelled after the vibration motor acts for 30 seconds, the old people is determined to be unconscious, and at the moment, the buzzer sends out sound to remind neighbors to rescue the old people.

The wheelchair can automatically dial the telephone of the emergency contact person through the background and automatically broadcast that the old people are unconscious at home through the background robot, the emergency contact person is asked to come home quickly, and the wheelchair control authority is given to the emergency contact person to prevent the old people from mistakenly touching the emergency contact person to cause unnecessary accidents in the unconscious state.

The use method of the toilet auxiliary standing wheelchair 100 comprises the following steps:

step 1, a user moves the standing-assisting toileting wheelchair 100 in the embodiment to the upper part of a closestool through a driving wheel 5;

and 2, sitting the closestool by the user for defecation.

After the toilet is finished, the user puts the arm on the handrail 204, the driving device 3 is electrified to rotate and drives the screw rod 202 to rotate, and the push rod 203 converts the circular motion of the screw rod 202 into linear motion, so as to push the handrail 204 to move upwards. The armrests 204 abut the armpits of the user during the upward movement and must be moved upward to assist the user in standing.

In the toilet using process, when the time reaches a preset signal, the timer sends a full time signal to the controller, the controller receives and processes the full time signal to generate a warning signal, the vibration motor starts to vibrate after receiving and executing the warning signal, and the buzzer starts to buzz after receiving and executing the warning signal, so that the time is reminded of arriving. If time delay is needed, a cancel button is pressed, and the vibration motor and the buzzer stop working at the moment; if the button is not cancelled after the vibration motor acts for 30 seconds, the old people is determined to be unconscious, and at the moment, the buzzer sends out sound to remind neighbors to rescue the old people.

And 3, after the use is finished, the user moves the defecation auxiliary standing wheelchair 100 in the embodiment to the initial position through the driving wheel 5.

In addition, the toilet auxiliary standing wheelchair in the embodiment can also provide a seat for a user, namely, the two sliding plates 6 are combined by driving the sliding plates 6 to rotate through the rotating motor 7.
