Fig. 1 is an overall structure diagram of the intelligent old-people-assisting walk-substituting device, as shown in fig. 1 to 6, the intelligent old-people-assisting walk-substituting device provided by the invention comprises four parts, namely a lifting seat, a chassis, a seat back and a controller, wherein the lifting seat is positioned above the chassis, the seat back is positioned behind the lifting seat, the controller is positioned on a toilet seat armrest 1 at one side of the lifting seat, and a driving mechanism is arranged below the chassis.

The lift seat includes like lavatory auxiliary cushion 6, elevator motor 5, T type connecting rod 17 and like lavatory armrest 4, and the lift seat passes through elevator motor 5 and realizes like rising and the decline effect of lavatory auxiliary cushion 6, elevator motor 5 with like lavatory auxiliary cushion 6 articulated, elevator motor 5 is controlled through intelligent control module by control button on the controller. The toilet auxiliary cushion 6 is a part which is directly contacted with the toilet and plays a role of gravity support when a user uses the toilet. Like lavatory seat handrail 4 install in the both sides like lavatory auxiliary cushion 6, for the user provides the auxiliary stay effect, like lavatory seat handrail 4 with like lavatory auxiliary cushion 6 together go up and down during the use, T type connecting rod 17 with it is supplementary like the lavatory cushion articulated, T type connecting rod 17 plays the supporting role to supplementary like lavatory cushion 6, like 6 reverse sides in lavatory auxiliary cushion install LED light 12 and be used for the illumination at night, LED light 12 is automatic to be opened when photosensitive sensor detects the ambient environment dim, the controller is installed like on lavatory seat handrail 4.

The back of the chair contains folding seat pad 7, back 8 and two back support columns 11, and when the user was with the help of this product like the lavatory, folding seat pad 7 fold behind the user with back 8 laminates, when the user was with the help of this product riding instead of walk, folding seat pad 7 can cover like the lavatory on the supplementary cushion 6. The back support column 11 is provided with a guide rail, the backrest 8 is fixed in the guide rail of the back support column 11 through a butterfly nut, and users with different heights can adjust the pressure between the bulge and the slide rail by adjusting the butterfly nut on the cross rod when using the product, so that the height of the chair back is suitable for the users.

The controller is provided with a direction rocker 3, a lifting button 2 and a mode selection button 1, and a user realizes the control effect of the invention through the control mechanism.

The pedestal is composed of two pedestal longitudinal rods 16, two upright connecting rods 24 and an upright cross-pull rod 32, a ribbed plate 20 is arranged between the pedestal longitudinal rods 16 and the upright connecting rods 24, a space capable of accommodating a toilet bowl is reserved behind the pedestal, and a driving mechanism is arranged below the pedestal.

The rear end lower part of the chassis longitudinal rod 16 is provided with a driving fork shaft support 14, the driving fork shaft support 14 is used for fixing the hub motor 15, the front end side surface of the chassis longitudinal rod 16 is provided with a front wheel fixing upright post 23, the front wheel fixing upright post 23 is a hollow cylinder, and the universal wheel support 21 can be sleeved in the front wheel fixing upright post 23 to rotate freely. The caster brackets 21 are used to fix the caster 22. The hub motor 15 and the universal wheel 22 form a driving mechanism body

As shown in fig. 2, two ends of the lifting motor 5 are hinged with the toilet auxiliary cushion 6 and the chassis longitudinal rod 16 through the hinge body 26 respectively, and it is difficult to know from mechanics knowledge that the lifting motor 5 is equivalent to a two-force rod, the direction of the supporting force of the lifting motor is inclined to the front upper side and is the same as the direction of the rod, the length of the lifting motor is 355mm, and the height of the rear supporting upright post is 306 mm. The included angle between the lifting motor 5 and the chassis longitudinal rod 16 at the initial position can be obtained by secsin (306/355), the thrust of the lifting motor 5 is 1000N, and the stress analysis can obtain that: the force of the lifting motor 5 on the toileting auxiliary cushion 6 in the vertical direction is 1000 × cos30.5 ° =861N, so that the left lifting motor 5 and the right lifting motor 5 can provide 1722N of supporting force in the vertical direction together, and the maximum load is 1722N/9.8=175.7 kg. Therefore, the product meets the normal use requirement of users with the weight not exceeding 175.7 kg.

This product accessible bluetooth module is connected with the smart mobile phone, can realize two long settings like the lavatory on cell-phone APP. When the pressure sensor detects a user and the photoelectric sensor detects the toilet, the intelligent control module starts timing, the alarm gives out sound to remind the user when the toilet time exceeds a first set value, and the intelligent control module sends information to the bound mobile phone to warn when the toilet time exceeds a second set value, so that the safety of the user is ensured to avoid accidents by the dual-alarm mechanism.

When photoelectric sensor detects the toilet bowl, intelligent control module sends the instruction and makes in-wheel motor 7 carry out the auto-lock to this keeps the automobile body stable, avoids the user to take place the accident. When the pressure sensor detects that the user leaves the lifting seat and the user dials the operating lever 3 to the front of the device, the self-locking of the hub motor 15 is released, and the problem of sudden movement of the device caused by mistaken touching of the user is avoided through two triggering conditions.

The invention has the indoor toilet assisting and outdoor walking replacing functions, a user can select the 1 button to manually adjust two modes through the mode on the controller, the indoor and outdoor advancing speeds of the device can be set on the mobile phone APP, and the indoor and outdoor speeds are independently set, so that the applicability of the device under different scenes is improved. Considering that most of household toilets have limited area and are inconvenient to turn and the device is suitable for the condition that the physical function of people is weak, the device does not have the function of walking replacement in an indoor mode by combining the requirement of the device on the relative spatial position of the toilet, the device is pushed by a user to advance, the driving wheel only provides low-speed assistance, the folding seat cushion 7 is in a folding state in the indoor mode, the pedal 27 is in the folding state, and the user pushes the device to move to the upper part of the toilet to assist in going to the toilet. Under the outdoor mode, this product folding seat pad 7 covers in like lavatory supplementary cushion 6 top for the open mode, and footboard 27 is the open mode, and the user sits in folding seat pad 6 top, and both feet are placed on both sides footboard 27, and the user passes through this device of control rod 3 control and removes.

This product power part has adopted in-wheel motor as the drive wheel, realizes the turn effect through controlling the speed governing, and the power part has chooseed the 24v lithium cell of 10AH as the light duration of power volume is strong, and battery department is equipped with charging control module, can obtain current battery power, convenient to use.
