Description

Technical Field

[0001] The utility model belongs to the technical field of life-assistance equipment, and particularly relates to a toilet-assistance device. Background Art

[0002] Sit-to-stand transitions require coordinated movement across the body, and insufficient lower limb strength may require assistance. For the elderly, as they age, their physiological changes gradually decline, leading to a significant decline in muscle and bone weakness and limb motor function, particularly in lower limb muscle strength and knee control. The elderly represent a special group in my country. With the country's aging population becoming increasingly serious, and children often unable to spend extended periods of time with their elderly due to busy work schedules, they are largely left to fend for themselves. Many elderly people have poor physical fitness and mobility issues, making it difficult for them to sit up when using the toilet due to the lack of adjustable toilet seat height, impacting their daily lives. Looking at the toilets and toileting devices currently available, it can be seen that assisted standing products are primarily divided into two types: fixed and movable. Fixed models require the elderly to stand up using their own arm strength by grasping the armrests on both sides, while movable models require the elderly to hold the armrests, press a button, and then the device guides them to stand up. Although these assistive product designs meet the special needs of the elderly and bring certain conveniences in the transition from sitting to standing in daily life, they generally have the following problems: First, the structure is simple and the function is relatively single. The bracket structure can only provide a force point, which makes it difficult for the elderly to get help in terms of strength. After the elderly stand up, they will still experience symptoms such as dizziness, making their toilet assistance less effective; second, the bracket structure is prone to secondary injuries to the elderly. The bracket is generally fixed on the left and right sides and the upper part of the toilet. It is easy for the elderly to trip and injure them when they walk unsteadily; third, the operating interface of the smart toilet is relatively cumbersome and the price is relatively expensive. Although the toilet is designed with comfort in mind, the safety of the toilet cannot be taken into account. Based on this, it is necessary and imperative to design a toilet assistance device that is easy to install and operate and has a certain degree of comfort and safety. Summary of the Invention

In addition to the groove, the groove rod A27 has two holes, and the groove rod B30 has a hole in front in addition to the groove. One of the holes in the groove rod A27 is connected to the hole of the groove rod B30 by a pin, and the other hole on the groove rod A27 is connected to the other end of the connecting rod B29 by a pin. The groove on the groove rod A27 is connected to the other end of the connecting rod A28 by a pin.

[0051] like Figures 7 and 8 As shown, this is a schematic diagram of a new type of toilet assist device of the present invention, wherein the groove rods B30 on the left and right sides are respectively installed on the left and right inner sides of the concave seat cushion 9 by screws. Armrests 4 are installed on both sides of the concave seat cushion 9. The concave seat cushion 9 is connected to the backrest 2 by a hinge 31. The backrest 2 is also connected to the support rod 19 through the support tube 8 to play a supporting and stable role. A telescopic protective cover 10 is provided between the support rod 19 and the support tube 8 to protect the internal parts of the device and prevent dust and the like from penetrating and damaging the parts. A waist assisting raising mechanism and an armpit assisting raising mechanism that can move up and down are provided inside the backrest 2.

The U-shaped brackets 7 at the upper and lower ends are both plastic designs, and the width can be adjusted according to actual conditions to effectively protect the waist. Bandages are provided at the ends of the U-shaped bracket 7, and the bandages are connected by buckles 3. A button 33 is provided at the middle connection of the buckle 3. When the button 33 is pressed, it can be unfastened and closed to prevent the elderly from tilting and falling during the standing-up process.

[0054] The utility model discloses a novel toilet assist device, the working principle of which is as follows:

[0055] Connect the power supply to the power interface of the control center. When in use, press the control button 1 to control the motors A24 on both sides of the control center to start working. Under the transmission of the coupling, the gear A16 rotates clockwise. At this time, the rack A17 is engaged with the gear A16 and fixed on the connecting tooth plate 25. The connecting tooth plate 25 is driven by the rack A17 to slide forward under the rotation of the gear A16, which drives the movement of the sliding link 26. When the sliding link 26 moves, the sliding link 26 drives the link A28 and the link B29 to change. At this time, the link A28, the link B29, the sliding link 26 and the groove rod B30 are connected by a pin at one end and move on the groove of the groove rod B30. The link B29 mainly plays the role of a stabilizing mechanism. The other end of the connecting rod A28 moves on the groove of the groove rod A27, causing the concave seat cushion to move obliquely upward until the plane forms an angle of 70 degrees at the same time. The backrest auxiliary raising mechanism makes the same movement when the backrest 2 and the concave seat cushion 9 are connected due to the hinge 31. The backrest 2 is restricted by the support tube 8 connecting the support rod 19, so it does not tilt at will. At the same time, the rangefinder continuously measures the moving distance of the sliding link 26 and feeds the information back to the control center. The control center controls the rotation of the motor A24 through the rangefinder signals on the left and right sides to ensure that the sliding links 26 on both sides move equidistantly. When the concave seat cushion 9 reaches the tilting degree, the gear A16 continues to rotate driven by the motor A24. The spring 22 is used to slow down the impact and ensure that the elderly person remains motionless in the resting state after standing up and will not fall. The elderly person adjusts the width of the U-shaped bracket 7 to an appropriate level, fastens the bandage buckle 3, and presses the control button 2. Under the action of the control center, the motor A24 starts to rotate in the opposite direction, and the power transmission mechanism, the connecting rod support movement mechanism and the backrest standing mechanism move in the opposite direction to the above until the concave seat cushion 9 is level. After the elderly person finishes using the toilet, he presses the control button 3, and the control center controls the motor B39 to start working. After the speed reducer 40 is decelerated, the gear B39 rotates clockwise under the drive of the coupling. Since the rack B34 is engaged with the gear B41, the underarm bracket 1 connected to the rack B34 by welding is As it moves upward, a gravity sensing device is provided on the armpit support 1. When the armpit support 1 senses gravity, the motor B39 stops rotating. At this time, press the control button 2, and the mechanism repeats the above starting action until the concave seat cushion 9 is at a 70-degree angle to the horizontal plane. Next, press the control button 3, and the control center controls the motor B39 to rotate in the opposite direction until the armpit support 1 does not feel the existence of gravity. The motor B39 stops rotating, and the elderly can leave after unfastening the buckle 3. At this time, the motor A24 generates a delay signal, the duration of which can be adjusted according to the user's needs. After completing the delay instruction, the motor A24 automatically reverses and resets to make the concave seat cushion level. Repeating the above movement can effectively help the elderly complete toileting.
