Description

Technical Field

[0001] This utility model relates to the field of electric assisted toilet chairs for the elderly, and in particular to an electric assisted toilet chair for the elderly. Background Technology

[0002] With the accelerating aging of my country's population, the needs for toilet care among elderly people with mobility issues and post-operative recovery patients are becoming increasingly prominent. Traditional toilets, lacking assistive functions for standing up, have become a significant safety hazard in the home. To address this, various assistive standing devices have emerged on the market, the most common being simple toilet chairs or those with added armrests that allow users to stand up using their arm strength. These devices provide a support point to some extent, assisting users with relatively good upper limb strength and marking progress in the concept of home-based elderly care. However, their design principles have inherent limitations and cannot universally meet the actual physiological conditions and safety needs of the core user group.

[0003] Specifically, the current mainstream method of standing up by supporting weight with the hands is not user-friendly and poses significant risks for elderly people who commonly suffer from upper limb weakness, arthritis, or neurological diseases (such as Parkinson's disease). The process of standing up requires the user to coordinate and apply continuous and sufficient hand strength. If the user becomes exhausted or slips, the support disappears instantly, easily causing the user to lose control and lean backward or sit back abruptly, potentially leading to hip contusions, uneven spinal stress, or even secondary injuries from falls. This feeling of being "powerless" also undermines the user's confidence in attempting independence. Therefore, how to move beyond simply relying on the user's physical abilities and develop a toileting assistance device that can actively and smoothly provide assistance, truly achieving safe and effortless standing, has become a key technological issue for improving the quality of life and care efficiency for the elderly. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing an electric assisted toilet chair for the elderly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design an electric assisted toilet chair for the elderly, including a base and a seat disposed on the upper part of the base. Folding components and two drive components for moving the two folding components are disposed between the base and the two sides of the seat. An anti-fall component is also disposed between the base and the seat. A control component for controlling the movement of the drive components is disposed on the base.

[0007] Furthermore, the folding assembly includes a four-bar linkage and a connecting rod that are rotatably connected to both ends of one side of the base, and the free end of the connecting rod is rotatably connected to one corner of the four-bar linkage.

[0008] Furthermore, the drive assembly includes a mounting base fixedly connected to the upper end of the base, an electric actuator rotatably connected to the mounting base, and the telescopic end of the electric actuator rotatably connected to one of the corners of the four-bar linkage.

[0009] Furthermore, the fall protection assembly includes a guide block fixedly connected to one side of the seat and a rod rotatably connected to the upper end of the base. The upper end of the rod has a guide groove adapted to the guide block, and the guide block is slidably connected to the guide groove.

[0010] Furthermore, the fall arrestor also includes a rack fixedly connected to one side of the rod and a ratchet rotatably connected to one side of the seat. A gear that meshes with the rack is fixedly connected to the outer side of the ratchet. A connecting post is fixedly connected to one side of the seat. An abutment rod is sleeved on the connecting post. A spring is fixedly connected between the abutment rod and the connecting post. Both ends of the abutment rod are provided with pawls that cooperate with the ratchet.

[0011] Furthermore, the control component includes a signal transmitter fixedly connected to the upper end of the base, handles fixedly connected to both sides of the seat, a control unit mounted on one of the handles, and the signal transmitter electrically connected to the electric actuator.

[0012] This utility model proposes an electric assisted toilet chair for the elderly, which has the following advantages: Through innovative drive components and a linkage folding mechanism, it achieves smooth and controllable lifting and lowering of the seat trajectory, providing users with active and continuous assistance in getting up. Furthermore, through an inclination angle design that conforms to the natural standing curve of the human body, it significantly reduces the stress on the waist and knee joints, making the act of getting up more effortless and comfortable. In addition, the anti-fall component constitutes a key safety redundancy, operating imperceptibly during uniform lifting and lowering, and instantly triggering a lock if the speed is too fast, effectively preventing accidental falls. This double protection ensures safety during use. The overall design organically combines active assistance, ergonomics, and passive protection, which not only effectively solves the core problem of getting up to use the toilet for the elderly and those with mobility difficulties, but also enhances their confidence and dignity in self-care from both physiological and psychological perspectives, while significantly reducing the workload and risks for caregivers.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-4 An electric assisted toilet chair for the elderly includes a base 1 and a seat 11 disposed on the upper end of the base 1. Folding components 2 and two driving components 3 for driving the two folding components 2 to move are disposed between the base 1 and the seat 11 on both sides. An anti-fall component 4 is also disposed between the base 1 and the seat 11. A control component 5 for controlling the movement of the driving components 3 is disposed on the base 1.

[0020] It should be noted that the folding assembly 2 includes a four-bar linkage 21 and a connecting rod 22 that are rotatably connected to both ends of one side of the base 1. The free end of the connecting rod 22 is rotatably connected to one corner of the four-bar linkage 21, and the free ends of the two four-bar linkages 21 are fixedly connected to both sides of the seat 11.

[0021] The four-bar linkage 21 is a conventional four-bar linkage mechanism consisting of four links that rotate and connect with each other, which will not be described in detail here. The four-bar linkage 21 is coordinated with the connecting rod 22 so that the four-bar linkage 21 will tilt when it moves during use.

[0022] Furthermore, the drive assembly 3 includes a mounting base 31 fixedly connected to the upper end of the base 1, and an electric actuator 32 rotatably connected to the mounting base 31. The telescopic end of the electric actuator 32 is rotatably connected to one of the corners of the four-bar linkage 21.

[0023] The electric actuator 32 pushes the four-bar linkage 21, thereby moving the seat 11 and assisting the patient to get up.

[0024] In this embodiment, the anti-fall component 4 includes a guide block 41 fixedly connected to one side of the seat 11 and a rod 42 rotatably connected to the upper end of the base 1. The upper end of the rod 42 is provided with a guide groove 49 adapted to the guide block 41, and the guide block 41 is slidably connected to the guide groove 49.

[0025] The guide block 41 and guide groove 49 work together to limit the rod 42, and no gap will be generated between the rack 43 and the gear 45 when the seat 11 moves.

[0026] The fall arrestor assembly 4 further includes a rack 43 fixedly connected to one side of the rod 42 and a ratchet 44 rotatably connected to one side of the seat 11. A gear 45 that meshes with the rack 43 is fixedly connected to the outer side of the ratchet 44. A connecting post 46 is fixedly connected to one side of the seat 11. An abutment rod 47 is sleeved on the connecting post 46. A spring 40 is fixedly connected between the abutment rod 47 and the connecting post 46. Both ends of the abutment rod 47 are provided with pawls 48 that cooperate with the ratchet 44.

[0027] When the seat 11 moves at a constant speed via the electric push rod 32, the gear 45 meshes with the rack 43. The gear 45 rotates at a normal speed, and the ratchet 44 strikes the lower pawl 48, causing the abutment rod 47 to rotate. However, it does not engage the other pawl 48 into the ratchet 44, allowing the device to move normally. After each strike, the abutment rod 47 is reset by the spring 40. When the seat 11 moves too fast, the frequency and force of the ratchet 44 striking the lower pawl 48 increase, causing the upper pawl 48 to engage into the ratchet 44, thus locking the ratchet 44 and stopping the entire device.

[0028] Based on the above embodiments, the control component 5 includes a signal transmitter 51 fixedly connected to the upper end of the base 1, and handles 12 fixedly connected to both sides of the seat 11. A control unit 52 is installed on one of the handles 12, and the signal transmitter 51 is electrically connected to the electric push rod 32.

[0029] The control unit 52 controls the signal transmitter 51, and then the signal transmitter 51 transmits the signal to the electric push rod 32 to move the seat 11.

[0030] Working method: When in operation, the base 1 is installed in a suitable position. When the patient needs to use it, they can choose to lay the seat 11 flat and sit on it directly, or raise the seat 11 and sit on it and then lower it. After use, the control component 5 controls the drive component 3 to move the folding component 2 so that the seat 11 can be raised so that the patient can get up.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
