Embodiment 1

[0058] see Figure 1-4 , this embodiment provides an automatic telescopic device for the elderly, which can be directly used as a toilet for people with disabilities, and can also be used as a wheelchair commonly used by people with disabilities, and can also be used as an auxiliary device Used in hospitals, homes and other places. Among them, the disabled can be elderly people with lower limb paralysis and severe leg diseases, doctors and patients who have undergone leg surgery or other parts of the surgery and cannot get up normally, or people with defects in their own legs. In this embodiment, the automatic telescopic device includes a seat 1, a lifting mechanism, a rocker mechanism, a sensing mechanism and a controller.

[0059] Generally, the seat 1 includes a frame 2 , a seat cushion 3 and a backrest 4 , and in this embodiment, the seat 1 also includes a plurality of driving wheels 14 , two armrests 17 and a plurality of cushions. In this embodiment, the bracket 2, the...

Embodiment 2

[0070] This embodiment provides an automatic retractable device for toilet for the elderly. On the basis of Embodiment 1, a lifting knob is added to the device. The lift knob is installed on the seat 1 and is used for rotation by the handicapped person to generate an electric signal of lift height. Wherein, the rotation angle of the lifting knob is directly proportional to the intensity of the lifting height electric signal. Here, the proportional relationship between the rotation angle and the electric signal strength can be realized by means of variable resistance. The controller is also used to obtain the corresponding lifting height according to the lifting height electrical signal, and then drive all the rod motors 5 to rotate, so that the seat cushion 3 rises or falls to the lifting height. Since the strength of the electrical signal is proportional to the rotation angle, the controller determines the lifting height according to the electrical signal and makes the seat ...

Embodiment 3

[0072] This embodiment provides an automatic retractable device for toilets for the elderly, which adds an emergency button and an emergency alarm on the basis of Embodiment 1. The emergency button is installed on the seat 1 and is used for people with reduced mobility to press to generate an emergency trigger signal. The emergency alarm is installed on the seat 1 and is used to generate an emergency alarm signal. The signal can be a voice signal, or a remote alarm signal transmitted to the guardian's mobile terminal through the remote control center. When the emergency button generates an emergency trigger signal, the controller drives the emergency alarm to send out an emergency alarm signal. When a person with limited mobility encounters an emergency, he can generate an emergency trigger signal by pressing the emergency button, and the controller detects the signal at this time and drives the emergency alarm to alarm, so that other nursing staff or guardians can wait for t...

Abstract

The invention discloses an automatic stretching and retracting device and method for an old-age-assisting toilet bowl. The device comprises a seat, a lifting mechanism, a rocker mechanism, a sensing mechanism and a controller. The seat comprises a support, a cushion and a backrest. Each lifting mechanism comprises a rod motor, a driving rod, a first bevel gear, a second bevel gear, a ball screw and a screw sleeve, and each rocker mechanism comprises a rocker motor, a first crank, a second crank, a first sensing mechanism pressure sensor and a second sensing mechanism pressure sensor. The controller firstly drives the cushion to ascend, a change curve of a leg pressing force is drawn, it is finally judged whether the leg pressing force is kept in a constant range or not, if yes, the rotation of the rod motor close to the cushion is stopped, the rotation of the rod motor far away from the cushion is stopped after the inclination angle of the cushion reaches a preset angle, and the rockermotor is finally driven to rotate to enable the cushion to move towards the direction of the person having difficulty in moving. The system is safer and more reliable, does not need to carry other equipment, and is more convenient to use.

Description

technical field [0001] The invention relates to an automatic telescopic device in the technical field of nursing instruments, in particular to an automatic telescopic device for toilet-aiding for the elderly, and also relates to a telescopic method of the device. Background technique [0002] For people with lower limb paralysis and severe leg diseases, especially the elderly, they cannot take care of themselves due to defecation problems and cause inconvenience to their young children. The specific steps for using a traditional toilet include: 1. Prepare items; equip the bathroom with handrails, toilet paper, and a toilet chair beside the bed; 2. The elderly use a wheelchair to enter the toilet and sit on the toilet; 3. The person wipes clean by himself or with the assistance of the nurse; 4. After sitting back in the wheelchair by using the hand-assisted getting up device, go back to the room to rest; The safety and reliability of the movement of the lower body parts driv...
