Description

Technical Field

[0001] This application relates to the field of smart home technology, and in particular to a smart toilet that helps the elderly get up and its usage method. Background Technology

[0002] People over 65 years of age generally suffer from lower limb muscle weakness, joint stiffness, and decreased balance. They are prone to falls, fainting, and other safety accidents, especially when getting up from the toilet. Therefore, developing an intelligent device that can actively assist the elderly in completing the toilet-getting-up action is of great practical significance.

[0003] While some toilet assistance devices for the elderly have emerged in the existing technology, they still have significant shortcomings in terms of structural integration and ease of use. For example, the "Multifunctional Toilet Seat for the Elderly and Disabled" disclosed in announcement number CN111904320B uses a foldable seat and drive component, along with a first and second support component to form a lifting mechanism, to mechanically assist the user in getting up. However, this technical solution is essentially an additional seat device independent of a regular toilet, requiring additional bathroom space and relying on rigid fixation to the floor and wall, making it unsuitable for direct adaptation to existing household toilets and limiting installation conditions. Furthermore, its bulky overall structure and distinctly medical-looking appearance can easily cause psychological burden for the elderly.

[0004] Although the existing technology has solved the problem of difficulty in getting up to some extent, its external seat structure and failure to integrate the assistive mechanism with the toilet body or toilet seat result in a large product size, poor versatility, and low aesthetics, making it difficult to popularize in ordinary household environments. At the same time, its drive method does not incorporate ergonomic optimization of the standing trajectory, which may cause excessive forward leaning or discomfort at the support point during the standing process, affecting the safety and comfort of use.

[0005] Based on this, the present invention provides a new technical solution to solve the above-mentioned technical problems. Summary of the Invention

The main seat cushion is connected to the guide rail via an arc-shaped slider that slides within an arc-shaped groove. A servo motor drives a screw to rotate, which in turn moves the first and second sliders. The main seat cushion is then propelled along the arc-shaped groove by a four-bar linkage.

[0010] Preferably, the armrest assembly is connected to the main seat cushion so that it rises and falls synchronously with the main seat cushion.

[0011] Preferably, it also includes a locking mechanism, which includes: Two sets of slider racks are connected to the first slider and the second slider, respectively; The locking rack engages disengagedly with the slider rack; The elastic element is used to drive the locking rack to move so as to engage or disengage with the slider rack; When the main seat is raised or lowered to the target position, the elastic element drives the locking rack to engage with the slider rack, thereby locking the position.

[0012] Preferably, the elastic element includes an electric actuator and a compression spring, the telescopic end of the electric actuator is connected to a locking rack, and the compression spring provides a tendency force to disengage the locking rack from the slider rack.

[0013] Preferably, the seat assembly also includes a toilet seat that is detachably mounted on the main seat, and a flip-top that is hinged to the rear end of the toilet seat via a damping hinge.

[0014] Preferably, the handrail assembly includes a handrail body, which includes a fixing block and a handrail plate that can slide and adjust relative to the fixing block.

[0015] Preferably, the base assembly is detachably connected to the toilet body via a snap-fit ​​structure.

[0016] Secondly, a method for using a smart toilet that helps the elderly get up includes the following steps: S1: Initially, the main seat is in the first state; S2: When the user needs to sit down, control the lifting assist mechanism to drive the main seat cushion to switch from the first state to the second state; S3: After the user sits on the main seat, the lifting assist mechanism is controlled to drive the main seat back from the second state to the first state; S4: When the user needs to get up, the lifting and assist mechanism is controlled to drive the main seat cushion to switch from the first state to the second state again to assist the user in getting up; S5: After the user stands up, the lifting and assist mechanism drives the main seat to reset from the second state to the first state.

[0017] In summary, this application includes the following beneficial technical effects: 1. This invention adopts a modular base assembly and snap-fit ​​connection design, which can be quickly installed without modifying the existing toilet. It is compatible with mainstream models on the market. The lifting and assisting mechanism and the seat cushion assembly are highly integrated, with a compact and beautiful structure. It avoids the space occupation and medical appearance of external auxiliary equipment, and is more in line with the needs and psychological acceptance of home environment.

[0018] 2. The main seat cushion of this invention rises smoothly along a preset ergonomic arc trajectory, actively adapting to the natural posture of the elderly when getting up, pushing the center of gravity forward, effectively reducing the load on the lumbar spine and lower limbs. The four-bar structure of the lifting assist mechanism works in conjunction with the arc-shaped guide rail to ensure smooth and unobstructed movement, providing a stable and natural experience for getting up.

[0019] 3. The present invention adds an electrically driven rigid locking mechanism, which can lock instantly at any position of the lifting and lowering, completely preventing the risk of accidental fall due to mechanism failure. The armrest assembly can be linked with the seat cushion to provide synchronous and stable lateral support. Attached Figure Description

Detailed Implementation

[0030] The following is in conjunction with the appendix Figures 1 to 9 This application will be described in further detail.

[0031] This application discloses an intelligent toilet that helps the elderly get up and its usage method, aiming to solve the problems of existing elderly-helping devices being independently external, having limited installation, lacking ergonomic optimization, and having safety hazards. Through an integrated base, a biomimetic arc-shaped lifting mechanism, and a multi-safety locking design, it achieves the technical effects of compact structure, convenient installation, and a comfortable, stable, safe, and reliable getting-up process.

[0032] Example 1: Reference Figure 1As shown, a smart toilet for assisting the elderly to get up includes a toilet body 1 and a base assembly 2 detachably installed on the toilet body 1. The base assembly 2 is used for the installation and fixation of other components. It is quickly connected to the toilet body 1 via a snap-fit ​​structure, without requiring modification to the existing bathroom facilities. The snap-fit ​​structure uses a combination of elastic snap-fit ​​and limiting protrusions to ensure that the base assembly 2 is securely installed and easy to disassemble, and is compatible with the shapes of mainstream toilet models on the market.

[0033] Reference Figure 2 As shown, the base assembly 2 consists of a first panel 201, a second panel 202, and a third panel 203. The three panels are connected by bolts, welding, or integral molding to form a stable load-bearing frame, providing sufficient installation space and structural support.

[0034] Specifically, the first panel 201 is horizontally positioned and has a through hole that matches the toilet opening of the toilet body 1, ensuring that excrement can fall smoothly into the sewer. Two sets of second panels 202 are vertically symmetrically positioned on both sides of the first panel 201 to support the lateral balance of a person after standing up. Their bottoms can be supported on the ground to enhance overall stability or suspended above the ground to accommodate toilet structures of different heights. The third panel 203, which has an arc-shaped structure, is connected between the two sets of second panels 202 and is located in front of the first panel 201. Its height is set at the same level as the second panel 202 (i.e., its bottom can be supported on the ground or suspended above the ground, and the specific setting is synchronized with the second panel 202), forming a U-shaped support frame, which effectively improves the overall structure's anti-tipping ability.

[0035] In addition, the base assembly 2 can be made of high-strength ABS engineering plastic or aluminum alloy, taking into account both lightweight and structural strength.

[0036] Reference Figure 3 As shown, a seat cushion assembly 3 is installed on the upper end of the base assembly 2. The seat cushion assembly 3 includes a main seat cushion 301 and a toilet seat 302. When the main seat cushion 301 is placed on the first panel 201, it is in the first state. At this time, the main seat cushion 301 is attached and fixed to the first panel 201, providing basic support and ensuring that the user's sitting posture is stable and comfortable. When it is necessary to assist in getting up, the main seat cushion 301 can be switched to the second state, that is, the main seat cushion 301 rotates and lifts forward and upward according to a preset arc trajectory, which drives the center of gravity of the human body to move forward and reduces the lumbar spine load when getting up.

[0037] Furthermore, the main seat 301 is oval-shaped and conforms to the toilet seat, with an antibacterial and non-slip silicone layer covering its surface to enhance comfort and safety. The toilet seat 302 is detachably installed on the main seat 301 for easy cleaning and replacement. It is secured to the main seat 301 via clips or magnetic attachments, maintaining stability during use. The toilet seat 302 is made of soft, skin-friendly material and is waterproof and stain-resistant, effectively improving hygiene. During the rotation and lifting of the main seat 301, the toilet seat 302 moves in tandem, ensuring synchronization and safety during posture changes.

[0038] The toilet seat 302 has a hinged flip-top 303 at its rear end. The flip-top 303 is hinged to the rear end of the toilet seat 302 via a damping hinge. The flip-top 303 can rotate in a vertical plane around the hinge point to close or open the toilet opening area at the rear of the toilet body 1. The damping hinge provides moderate rotational resistance, allowing the flip-top 303 to stay at any opening angle, making it easy for users of different heights to adjust to a comfortable position, while avoiding the risk of noise or pinching from rapid descent. In addition, the flip-top 303 can be used to support the user's back while using the toilet, reducing lumbar pressure.

[0039] Reference Figure 4 and Figure 5 As shown, in order to achieve a smooth switching of the main seat cushion 301 between the first state and the second state, the present invention connects the output end of the lifting assist mechanism 4 below the main seat cushion 301. The lifting assist mechanism 4 has two sets, which are symmetrically arranged on both sides below the main seat cushion 301 and installed on the outside of the second panel 202. Through synchronous driving, the main seat cushion 301 is smoothly raised or lowered along a preset trajectory.

[0040] The lifting assist mechanism 4 includes a drive component, a support component, and a guide rail component. Specifically, the drive component is used to drive the support component to operate. One end of the support component is connected to the lower end of the main seat cushion 301, and the other end cooperates with the guide rail component. By driving the support component through the drive component, the main seat cushion 301 can be driven to move along a preset arc trajectory, so that the main seat cushion 301 can smoothly switch between the first state and the second state, ensuring smooth and unhindered movement. The guide rail component is used to guide the main seat cushion 301 to move along the set arc path, ensuring that the center of gravity transfer is natural and stable during the lifting stroke.

[0041] Specifically, the guide rail includes an arc-shaped slide block 401 fixedly installed on the side of the second panel 202. The arc-shaped slide block 401 has an arc-shaped groove, the arc of which is consistent with the preset trajectory path of the main seat cushion 301, to ensure the accuracy and stability of the main seat cushion 301's movement trajectory. An arc-shaped slider 402 is slidably installed in the arc-shaped groove, and the upper end of the arc-shaped slider 402 is fixedly connected to the lower side of the main seat cushion 301 to ensure synchronous movement. Slide strips 403 are fixedly installed on both sides of the arc-shaped slider 402, and guide grooves matching the slide strips 403 are opened in the inner side of the arc-shaped groove to ensure that the arc-shaped slider 402 does not deflect during sliding and to keep the main seat cushion 301 running smoothly. The slide strips 403 and the guide grooves adopt a low-friction material embedded design to reduce movement resistance.

[0042] The driving component includes a fixed base 405. Two sets of fixed bases 405 are horizontally mounted on the outer side of the second panel 202 and are located on the same side of the second panel 202 as the guide rail. A drive shaft is mounted between the two sets of fixed bases 405 through a bearing. The drive shaft is a screw 406. One end of the drive shaft is connected to a servo motor 407, which drives the screw 406 to rotate.

[0043] The support includes a first slider 408, a first connecting rod 409, a second slider 410, and a second connecting rod 411. Both the first slider 408 and the second slider 410 are sleeved on the screw 406 and threadedly engaged with the screw 406. The first slider 408 is located at the front end of the threaded section of the screw 406, and the second slider 410 is located at the rear end. When the servo motor 407 drives the screw 406 to rotate, the first slider 408 and the second slider 410 move axially along the screw 406. The lower end of the first connecting rod 409 is hinged to the upper end of the first slider 408 through a hinge shaft, and the upper end is hinged to the lower end of the main seat cushion 301. The lower end of the second connecting rod 411 is hinged to the upper end of the second slider 410, and the upper end is hinged to the lower end of the main seat cushion 301. The two sets of connecting rods expand or contract synchronously under the drive of the sliders, forming a four-bar linkage lifting mechanism, which pushes the main seat cushion 301 to move smoothly along an arc trajectory.

[0044] In summary, when the user begins use, the servo motor 407 is first driven to rotate forward, causing the screw 406 to rotate synchronously. This causes the first slider 408 and the second slider 410 to move forward, which in turn pushes the first connecting rod 409 and the second connecting rod 411 to unfold synchronously. This causes the main seat cushion 301 to rise smoothly along the preset trajectory of the arc-shaped slide, achieving a switch from the first state to the second state. This causes the main seat cushion 301 to tilt forward and lift, conforming to the forward shift of the human body's center of gravity. At this time, the user can naturally sit on the main seat cushion 301 and obtain sufficient support. Afterward, the servo motor 407 rotates in the opposite direction, and the screw 406 reverses accordingly. The first slider 408 and the second slider 410 move in the opposite direction, causing the first connecting rod 409 and the second connecting rod 411 to close synchronously. The main seat cushion 301 smoothly falls back to the first state along the arc-shaped slide, completing the closing action. At this time, the user is sitting steadily on the cushion and begins to use the toilet.

[0045] When the toilet use is finished, the servo motor 407 rotates forward again, driving the screw 406 to rotate forward. The first slider 408 and the second slider 410 move forward again along the axial direction, pushing the first connecting rod 409 and the second connecting rod 411 to unfold synchronously. The main seat cushion 301 then smoothly rises to the second state along the arc-shaped slide, with the forward tilt angle conforming to the forward shift of the user's center of gravity, making it easy for the user to get up naturally with smooth and unobstructed movements. Subsequently, the servo motor 407 rotates in the reverse direction, the screw 406 reverses, and the first slider 408 and the second slider 410 move in the opposite direction, driving the first connecting rod 409 and the second connecting rod 411 to close synchronously. The main seat cushion 301 smoothly falls back to the first state along the arc-shaped slide, completing the closed reset and ensuring that the device returns to its initial shape, waiting for the next use command.

[0046] The entire process is controlled by a servo motor 407, which automates the lifting and lowering of the main seat cushion 301 and enables posture self-adaptation, effectively reducing the burden on users when getting up and sitting down, especially suitable for the elderly or those with mobility impairments; in addition, the structural design of this application takes into account both stability and response speed, the four-bar linkage moves smoothly, and the arc-shaped slide groove limit prevents shaking and jamming; at the same time, based on ergonomic principles, the forward tilt angle of the main seat cushion 301 when it is raised can adapt to the needs of different body types, making it suitable for smart toilet applications in homes and public places.

[0047] Reference Figure 4 and Figure 6 As shown, in addition to the above, this application also includes two sets of armrest assemblies 5, which are symmetrically arranged on both sides of the main seat cushion 301 and installed on the second panel 202 on the corresponding side.

[0048] Specifically, the armrest assembly 5 includes a fixed support rod 501, an elbow joint 502, and an armrest body 503. The elbow joint 502 is bent at 90°, with one end horizontally detachably connected to the rear end of the armrest body 503, and the other end vertically downwards detachably connected to the upper end of the fixed support rod 501. A base 504 is detachably installed at the lower end of the fixed support rod 501, providing stable support for the armrest assembly 5. The 90° structure of the elbow joint 502 keeps the armrest body 503 in a horizontal position, making it easier for users to grip and use for support, especially providing lateral support during sitting and getting up, enhancing safety and comfort. The detachable connection method facilitates installation, adjustment, and later maintenance, adapting to different spatial layout requirements.

[0049] In this embodiment, the base 504 is preferably installed on the fixed base 405 at the rear end of the second panel 202. In other embodiments, the base 504 can also be directly fixed to the pre-reserved mounting holes on the second panel 202 to adapt to different installation environments.

[0050] Meanwhile, the fixed support rod 501 can also be designed with an adjustable height. By setting multiple positioning holes and limiting pins on the fixed support rod 501, the height of the handrail body 503 can be flexibly adjusted to meet the needs of users of different heights.

[0051] In addition, in this embodiment, the armrest body 503 includes a fixing block 505, which is elongated and detachably connected to the elbow joint 502 at its rear end. A sliding hole is provided at the front end of the fixing block 505, and an adjusting rod 506 is slidably fitted in the sliding hole. One end of the adjusting rod 506 extends out of the sliding hole and is connected to the armrest head 507. The upper surface of the armrest head 507 is flush with or slightly higher than the upper surface of the fixing block 505, and an armrest plate 508 is installed on its upper end. The lower surface of the armrest plate 508 is slidably fitted with the upper surface of the fixing block 505. The armrest plate 508 can slide and adjust along the length direction on the upper surface of the fixing block 505 with the armrest head 507 to adapt to the natural arm placement position of the user's arm in a sitting posture, thereby improving support comfort. The upper surface of the armrest plate 508 is covered with an anti-slip soft rubber layer 509, which effectively prevents slippage when the hands are sweaty and improves grip safety.

[0052] In other embodiments, the sliding hole can be an internally threaded hole, the outer periphery of the adjusting rod 506 is provided with a threaded section that mates with it, and the front end of the adjusting rod 506 extends out of the armrest head 507 and is equipped with a knob 510. The adjusting rod 506 is installed in the armrest head 507 through a bearing. By rotating the knob 510, the adjusting rod 506 is driven to spirally feed in the sliding hole, so as to realize the stepless adjustment and self-locking of the position of the armrest plate 508. The operation is convenient and the structure is stable. After rotating to the correct position, the position of the armrest plate 508 can be accurately fixed, avoiding slippage during use.

[0053] Reference Figure 1 and Figure 7As shown, in addition, a protective shell 6 is provided on the outer side of the second panel 202. The protective shell 6 and the second panel 202 form a receiving cavity to accommodate internal components such as the lifting assist mechanism 4. This improves the overall appearance and safety. The protective shell 6 is injection molded from high-strength ABS material and has a matte finish, which combines wear resistance and impact resistance, effectively preventing external bumps from damaging the internal mechanism.

[0054] Example 2: Reference Figure 7 and Figure 8 As shown, based on Embodiment 1, this embodiment provides another armrest component 5. In Embodiment 1, the armrest component 5 is installed on the second panel 202, and it cannot move in position with the main seat cushion 301, which affects the support effect. In this embodiment, the armrest component 5 is linked with the main seat cushion 301, so that the armrest component 5 moves in and out of position with the main seat cushion 301, and always maintains the same relative position, effectively avoiding the discomfort caused by the shift of the support point during sitting up.

[0055] Specifically, unlike Embodiment 1, the handrail assembly 5 does not include the elbow joint 502, and the upper end of the fixed support rod 501 is detachably connected to the lower end of the fixed block 505.

[0056] Furthermore, in this embodiment, mounting bases 7 are integrally formed on both sides of the main seat cushion 301. Mounting bases 7 have mounting holes. The lower end of the fixed support rod 501 is inserted into the mounting hole and locked with fasteners (or fixed by threaded connection), so as to realize quick disassembly and assembly and stable connection of the armrest assembly 5, which is convenient for later maintenance or replacement. In this embodiment, two sets of fixed support rods 501 are preferably selected and arranged symmetrically to enhance the stability of the overall structure and symmetrical force distribution, so as to ensure that the user receives balanced support during sitting and getting up.

[0057] Furthermore, refer to Figure 3 and Figure 8 As shown, a placement box 701 is fixedly installed on one side of one of the mounting bases 7 for placing the controller 702. The placement box 701 is fixed to the mounting base 7 by a buckle or screw. The controller 702 is used to control the coordinated operation of the various drives of this application, such as realizing the lifting and lowering of the seat cushion.

[0058] Example 3: Reference Figure 9 As shown, based on Embodiment 1, since the lifting assist mechanism 4 in Embodiment 1 adopts a screw thread engagement drive method with a slider, and the users targeted by this application are specific groups such as the elderly or patients in the rehabilitation period with weak mobility, this application has higher requirements for the stability and safety of the lifting process.

[0059] However, the screw drive in Embodiment 1 carries a risk of slippage. For example, when the main seat cushion 301 bears excessive weight or the screw is worn, slippage and instability may occur, posing a safety hazard. Specifically, when the main seat cushion 301 is in the second state and the user is in the process of sitting up or getting up, if the lifting assist mechanism 4 suddenly slips, the main seat cushion 301 may fall instantly, endangering the user's safety. Therefore, this embodiment adds a locking mechanism to the lifting assist mechanism 4 to ensure that the main seat cushion 301 can achieve rigid limiting and double protection when it is stopped in any position.

[0060] Specifically, the locking mechanism is located below the screw 406 and mounted on the second panel 202. It includes a locking seat 801, which is fixed to the second panel 202 by screws. The locking seat 801 has a through hole running vertically through it, and a locking rack 802 is slidably mounted in the through hole.

[0061] Both the first slider 408 and the second slider 410 are fixedly connected to a connecting block 803 at their lower ends. The lower end of the connecting block 803 is detachably fitted with a slider rack 804 that meshes with the locking rack 802. When the main seat 301 is raised or lowered, the slider rack 804 moves synchronously with the first slider 408 and the second slider 410. At this time, the locking rack 802 remains disengaged from the slider rack 804 under its own weight or the action of an elastic element. When the main seat 301 stops rising or falling and is positioned at any height, the locking rack 802 moves upward in a controlled manner until it is fully engaged with the slider rack 804, forming a rigid limiting structure, which effectively prevents the main seat 301 from falling accidentally due to the failure of the screw 406.

[0062] The elastic element includes a fixed plate 805, which is fixedly connected to the lower end of the locking seat 801 by screws. A guide rod 806 is fixedly connected to the lower end of the locking rack 802. The lower end of the guide rod 806 passes through the guide hole on the fixed plate 805, and a compression spring 807 is sleeved on the outer periphery of the guide rod 806. One end of the compression spring 807 abuts against the fixed plate 805, and the other end abuts against the lower end face of the locking rack 802. Under normal conditions, the elastic force keeps the locking rack 802 in a downward trend, ensuring that the slider rack 804 and the locking rack 802 are disengaged, so as to facilitate smooth lifting and lowering.

[0063] An electric push rod 808 is also installed on the fixed plate 805. The telescopic end of the electric push rod 808 is vertically upward and connected to the lower end face of the locking rack 802. When the main seat 301 is raised or lowered to the target height, the controller 702 controls the electric push rod 808 to extend, pushing the locking rack 802 to move upward against the spring force, so that it engages with the slider rack 804 to achieve position locking. When it is necessary to continue to adjust the height, the electric push rod 808 retracts, and the locking rack 802 resets and disengages under the action of the spring, ensuring that the raising and lowering action is not hindered.
