Description

Technical Field

[0001] This invention is a flip-support type centrally located single push rod elderly care transfer robot, belonging to the field of nursing transfer robot technology. Background Technology

[0002] In hospital wards, nursing homes, and home-based elderly care settings, the transfer of patients between beds, wheelchairs, and commodes is a high-frequency nursing task. Traditional manual handling methods are labor-intensive and can easily cause back muscle injuries to caregivers, while also causing secondary strains and compression injuries to patients. The industry has widely adopted electric nursing transfer robots to replace manual transfer.

[0003] Currently, nursing transfer robots on the market have initially achieved automated transfer functions, but their overall structure is highly homogeneous, patent barriers are dense, safety redundancy is insufficient, body position adaptability is poor, and scene adaptability is limited. They are difficult to meet the modern health care needs of high precision, high safety, full body posture, and small space. The industry urgently needs a new type of transfer device with differentiated structure, high safety, wide adaptability, and avoidance of patent risks.

[0004] Currently available nursing transfer robots of the same type generally have fixed defects in their structural design: the support mechanism is mostly an integrated rigid fixed structure, the backrest and seat are linked for adjustment, and it cannot be flipped independently, so it can only be used to transport patients in a standard sitting position; the anti-tipping structure almost all adopts external telescopic support legs and tail counterweight structure, and this type of structure has been covered by a large number of prior patents, so new equipment directly adopting it has an extremely high risk of infringement.

[0005] Meanwhile, existing equipment's lifting rods are mostly exposed, straight-top structures without enclosed protective structures. In health and wellness settings, they are prone to water ingress, dust accumulation, and deformation from impacts during frequent disinfection and daily cleaning, resulting in high equipment failure rates and short lifespans. In terms of safety design, traditional equipment relies solely on basic power-on start / stop, lacking travel limit protection, mechanical separation structures in the event of power failure, and button locking to prevent accidental touches. Furthermore, most operate in a continuously powered mode, making it highly susceptible to accidents if operators drop their hands or the equipment exceeds its travel range. The walking structure is mostly a symmetrical four-wheel layout with no differentiated drive or follow-up design. It cannot turn around in place in narrow bedside areas, resulting in poor operational flexibility. It also lacks a manual emergency unlocking structure, rendering it immobile when the power is off, thus limiting its emergency practicality.

[0006] A flip-support type centrally located single push rod elderly care transfer robot is provided to solve the above problems. Summary of the Invention

[0007] To address the shortcomings of existing technologies, the purpose of this invention is to provide a flip-support type centrally located single push rod elderly care transfer robot.

Two sleeves are provided between the two square lifting guide tubes. The upper and lower sleeves are respectively fixed to opposite sides of the upper outer shell and the middle outer shell. An upper and lower electric push rod is fixedly installed inside the lower sleeve. The telescopic end of the upper and lower electric push rods is connected and fixed to the upper sleeve. A top plate is fixed at the top center of the upper outer shell.

[0010] Furthermore, the central circular plate includes a connector and a circular sheet, the circular sheet being fixed to the outside of the connector, and the connector being fixed to the middle of the upper outer shell.

[0011] Furthermore, the square lifting conduit includes a first external conduit and a second external conduit. The first external conduit and the second external conduit are respectively fixed on opposite sides of the upper shell and the middle shell. An internal guide rod is fixed at the center of the second external conduit, and the first external conduit is vertically slidably sleeved on the internal guide rod.

[0012] Furthermore, the seat mechanism includes a seat rotation assembly and a seat portion. The seat rotation assembly includes a first flip electric push rod fixed to the outer surface of the first external guide tube. The bottom telescopic end of the first flip electric push rod is movably connected to the top end of a right-angle connecting bend. The bottom end of the right-angle connecting bend is movably connected to the end of an integrated rotating shaft. The integrated rotating shaft is movably connected to the other outer surface of the first external guide tube via a bearing with a seat. The end of the integrated rotating shaft is connected to the seat portion. The seat portion includes a seat shaft. One end of the seat shaft is fixedly connected to the end of the integrated rotating shaft, and the other end of the integrated rotating shaft is fixedly connected to the seat. A seat pad is provided on the seat.

[0013] Furthermore, the backrest mechanism includes a backrest flipping assembly, a clamping arm portion, a backrest portion, and a support portion. The backrest flipping assembly includes a head beam fixed to the bottom of the upper housing. Two second flipping electric push rods are symmetrically mounted on the bottom of the head beam. The telescopic ends of the second flipping electric push rods are movably connected to one end of the backrest connecting hook. The other ends of the two sets of backrest connecting hooks are movably connected to the ends of the right backrest pivot and the left backrest pivot, respectively. The right backrest pivot and the left backrest pivot are movably connected to the bottom of the head beam through a set of bearings. The ends of the right backrest pivot and the left backrest pivot extend to the outside of the upper housing and are connected to the clamping arm portion. The backrest portion and the support portion are fixed to the clamping arm portion.

[0014] Furthermore, the backrest portion includes a backrest panel and a backrest cushion, the backrest panel being fixed to the end of the clamping arm portion, and the backrest cushion being fixed to the backrest panel.

[0015] Furthermore, the support portion includes a support shell, a support plate, and a support pad. The support shell is fixed to the clamping arm portion, the support plate is fixed to the end of the support shell, and the support pad is fixed to the support plate.

[0016] Furthermore, a reversing camera is installed at the bottom of the base, a display screen is installed at the top of the top plate, and a battery slot is installed at the bottom inner part of the middle shell, with a battery installed inside the battery slot.

[0017] Furthermore, a control unit is also installed on the upper housing. The reversing camera and the display screen are electrically connected to the control unit. The control unit includes a joystick, a first control button, and a second control button. The joystick, the first control button, and the second control button are fixed on the upper housing. The joystick is equipped with a joystick button.

[0018] The beneficial effects of this invention are: This invention features two independent flipping drive mechanisms. The seat mechanism is driven by a first flipping electric push rod, and the backrest mechanism is driven by a second flipping electric push rod. The seat and backrest can flip independently without interfering with each other. They can be combined into a standard sitting posture for elderly people with good mobility, or adjusted into a semi-reclining or cuddling posture to suit severely disabled elderly people with stiff limbs who are unable to maintain a sitting posture independently, thus expanding the applicable population of the device.

[0019] The present invention uses an electric push rod for lifting and lowering, which is arranged in two sleeves inside the middle and upper outer shells, forming a completely enclosed and protected structure, unlike the traditional exposed push rod structure. On the one hand, this can prevent water and dust from entering during disinfection and rinsing, prevent foreign objects from bumping into it, reduce the probability of failure, and extend the service life of the equipment. On the other hand, the centrally located single push rod is combined with square lifting guide tubes on both sides for guidance, eliminating the need for the traditional anti-tipping scheme of external telescopic support legs and tail counterweight. The square lifting guide tubes, together with the internal guide rods, achieve vertical guidance, resulting in smooth lifting and lowering operation and strong resistance to lateral tipping.

[0020] This invention is equipped with a joystick, multiple control buttons, and a joystick button for overall machine operation. A button lock prevents accidental touches and misoperation. It features a reversing camera monitoring system with a display screen on the top panel, allowing caregivers to observe the environment behind the equipment in real time, avoiding obstacles during relocation and preventing collisions with the elderly or furniture. The entire mechanism can be equipped with travel limit switches for overtravel stop and anti-pinch protection. It can also be combined with a power-off mechanical separation emergency structure, which releases the mechanism lock in the event of a power outage.

[0021] The base of this invention adopts a layout of drive wheels and follow-up omnidirectional wheels. The electric motor drives the wheels to provide walking power, and the omnidirectional wheels realize steering. The base is equipped with a brake baffle to realize parking braking. The whole machine can flexibly turn in narrow spaces such as bedside and bathroom, solving the problem of difficult turning in place in traditional four-wheel symmetrical structures. In the event of a power failure, the brake and walking mechanism can be manually unlocked. If the equipment is stuck due to power failure, it can be manually pushed, improving emergency handling capabilities.

[0022] The battery of this invention is arranged in a battery slot inside the central outer casing, which is built-in and makes it easy to disassemble and replace the battery; each mechanism adopts modular assembly, and the bearing with seated bearing realizes the rotation support of the shaft, making assembly, inspection and maintenance simple; the backrest and seat are equipped with soft pads, and the support part is equipped with support pads to improve the comfort of the elderly when being carried.

[0023] The base, lifting housing, and supporting actuator of this invention are stacked vertically, resulting in a compact structure and controllable overall size. This design is suitable for mass use in nursing home wards as well as for indoor use in home-based elderly care environments. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-6 This invention provides a technical solution for a flip-and-hold type centrally mounted single-push-rod elderly care transfer robot, including a base part 6, which includes a base 601. The bottom rear side of the base 601 is equipped with a brake baffle 602, omnidirectional wheels 5, and a reversing camera 14. The two sets of omnidirectional wheels 5 have no independent power output and adopt a fixed 85° inward tilting installation structure. The wheel set and the base 601 form a stable triangular adaptive support system, which is a passive anti-tipping structure. It requires no electrical control or mechanical extension adjustment, and completely follows the front wheel drive synchronously for steering. The entire machine moves smoothly and steers flexibly. During lifting, flipping, and center of gravity shifting, the 85° inward tilting wheel set can autonomously counteract the front-to-back and left-to-right tilting moments, continuously maintaining the horizontal stability of the machine body, thus eliminating the risk of tipping over from the structural root. To address issues of tilting, tipping, and falling over, the base 601 has a base housing 603 installed at its front end. Wheels 7 are symmetrically mounted on both sides of the bottom of the base housing 603. The wheels 7 are connected to motors 18, which are installed at the bottom of the base housing 603. The two sets of motors 18 output power independently, enabling differential speed control and allowing the equipment to move forward, backward, turn at multiple angles, and rotate 360° in place. This adapts to confined working spaces such as gaps between hospital beds and bathrooms. The wheels 7 integrate an electromagnetic brake module, which is in a default self-locking state when power is off, automatically locking the wheels after the equipment stops to prevent slippage. A baffle 17 is installed on the top of the base portion 6. A lifting housing is located on the front side of the baffle 17, and a seat mechanism and a backrest mechanism are located inside the lifting housing.

[0029] See Figures 1-2The lifting housing includes a central outer shell 12, which is fixed to the top of the base outer shell 603 and located at the front end of the baffle 17. A central circular plate 11 is fixed at the center of the top of the central outer shell 12. Square lifting guide tubes 20 are symmetrically fixed inside the central outer shell 12. The square lifting guide tubes 20 include a first external guide tube 2002 and a second external guide tube 2003. The first external guide tube 2002 and the second external guide tube 2003 are respectively fixed to opposite sides of the upper outer shell 10 and the central outer shell 12. An internal guide rod 2001 is fixed at the center of the second external guide tube 2003. An external conduit 2002 is vertically slidably sleeved on the internal guide rod 2001. The top telescopic end of the square lifting conduit 20 is connected to the upper outer shell 10. As the main load-bearing body of the whole machine, it has strong structural rigidity, is not easily deformed, and has high assembly precision. The upper outer shell 10 is located above the middle outer shell 12. The bottom of the upper outer shell 10 is provided with a mating groove that matches the middle circular plate 11 and an upper-middle outer shell connector 16 that matches the middle outer shell 12. Two sleeves 2005 are provided between the two square lifting conduits 20. The upper and lower sleeves 2005 are respectively fixed to the upper outer shell 10 and the middle outer shell 12. On one side, an upper and lower electric push rod 2004 is fixedly installed inside the lower sleeve 2005. The telescopic end of the upper and lower electric push rod 2004 is connected and fixed to the upper sleeve 2005.

The rocker arm 801, the first control button 802, and the second control button 803 are fixed to the upper housing 10. A rocker arm button 804 is provided on the rocker arm 801.

[0030] See Figures 3-4The seat mechanism includes a seat rotation assembly 19 and a seat portion 4. The seat rotation assembly 19 includes a first tilting electric push rod 1901 fixed to the outer surface of the first external guide tube 2002. The bottom telescopic end of the first tilting electric push rod 1901 is movably connected to the top end of a right-angle connecting bend 1902. The bottom end of the right-angle connecting bend 1902 is movably connected to the end of an integrated rotating shaft 1903. The integrated rotating shaft 1903 is movably connected to the other outer surface of the first external guide tube 2002 via a bearing 13. The end of the integrated rotating shaft 1903 is connected to the seat portion 4. The seat plate portion 4 includes a seat shaft 403, one end of which is fixedly connected to the end of the integrated rotating shaft 1903, and the other end of which is fixedly connected to the seat plate 401. A seat pad 402 is provided on the seat plate 401. In use, the first flip electric push rod 1901, the seated bearing 13, and the linkage transmission assembly can accurately achieve a 45° standardized up-and-down flipping opening and closing action. The seat plate 401 can be flipped upward to allow the bedside to be cleared, making it convenient for the equipment to be close to the bed and quickly align with the patient. The downward flipping can form a stable horizontal support platform, which is suitable for the non-destructive transfer of patients in various body positions.

[0031] See Figures 5-6The backrest mechanism includes a backrest flipping assembly 24, a clamping arm portion 3, a backrest portion 1, and a support portion 2. The backrest flipping assembly 24 includes a head beam 22 fixed to the bottom of the upper housing 10. Two second flipping electric push rods 2404 are symmetrically installed at the bottom of the head beam 22. The telescopic ends of the second flipping electric push rods 2404 are movably connected to one end of the backrest connecting hooks 2403. The other ends of the two sets of backrest connecting hooks 2403 are movably connected to the ends of the right backrest rotating shaft 2401 and the left backrest rotating shaft 2402, respectively. The right backrest rotating shaft 2401 and the left backrest rotating shaft 2402 are movably connected to the bottom of the head beam 22 through a set of bearings 13. The ends of the right backrest rotating shaft 2401 and the left backrest rotating shaft 2402 extend to the outside of the upper housing 10 and are connected to the clamping arm portion 2. The arm part 3 is connected, and the backrest part 1 and the support part 2 are fixed on the clamping arm part 3. The backrest part 1 includes a backrest plate 101 and a backrest pad 102. The backrest plate 101 is fixed to the end of the clamping arm part 3, and the backrest pad 102 is fixed to the backrest plate 101. The support part 2 includes a support shell 201, a support plate 202, and a support pad 203. The support shell 201 is fixed to the clamping arm part 3, the support plate 202 is fixed to the end of the support shell 201, and the support pad 203 is fixed to the support plate 202. In use, the backrest can be rotated and connected to the linkage transmission structure through the seated bearing 13 to achieve a controllable up and down flipping support action. The backrest tilt angle can be adaptively adjusted according to the patient's different body postures such as lying flat, lying on the side, and sitting, closely conforming to the curve of the human back and achieving flexible and pressure-free support.

[0032] This flip-and-hold type centrally located single push rod elderly care transfer robot consists of four core movements: walking, lifting, seat flipping, and backrest flipping. It is powered by the built-in battery 23, and all movements are uniformly scheduled by the control unit. Caregivers can complete the operation through the joystick 801 and control buttons.

[0033] When the device is in motion, the caregiver operates the joystick 801 on the upper housing 10, which transmits the control signal to the motor 18. The motor 18 drives the wheels 7 on both sides of the bottom of the base housing 603 to rotate, enabling the device to move forward and backward. The universal wheels 5 on the rear of the base 601 follow the direction of rotation, completing the turning action. The base 601 is equipped with a brake baffle 602, which can be used to park the device when it is in position, preventing it from slipping. The reversing camera 14 collects the image behind the device and transmits it to the display screen 15 in real time, allowing the caregiver to visually view obstacles behind the device and ensure safety during the relocation process. When the device is powered off, the brake baffle 602 can be manually unlocked to allow manual pushing.

[0034] During the lifting and lowering operation of the entire machine, the lifting and lowering action is achieved by the centrally located upper and lower electric push rods 2004. The upper and lower electric push rods 2004 are installed inside the sleeve 2005. The sleeve 2005 is connected to the upper outer shell 10 and the middle outer shell 12 respectively. When the upper and lower electric push rods 2004 extend and retract, they drive the upper outer shell 10 to perform vertical lifting and lowering movements. The internal guide rods 2001 of the square lifting guide tubes on both sides and the first external guide tube 2002 slide and cooperate with each other to guide and constrain the lifting and lowering movements, ensuring that the upper outer shell 10 will not deviate or shake when it is lifted and lowered. This allows for adjustment of the overall height of the seat mechanism and backrest mechanism, adapting to different height positions of hospital beds, wheelchairs, and toilets, making it convenient for the elderly to be admitted and removed.

[0035] When the seat 401 is flipped, the flipping of the seat 401 is completed by the seat rotation assembly: the first flipping electric push rod 1901 is fixed on the outer surface of the first external guide tube 2002, the extension end of the push rod pushes and pulls the right angle connecting bend 1902, the right angle connecting bend 1902 drives the integrated rotating shaft 1903 to rotate around the bearing 13 with seat; the integrated rotating shaft 1903 synchronously drives the seat shaft 403 and the seat 401 to rotate, realizing the angle adjustment of the seat 401 to lift upward and flatten downward, and the seat tilt angle can be adjusted according to the elderly's physical condition to complete the support and cuddling.

[0036] When the backrest part 1 and the clamping arm part 3 are flipped, the second flipping electric push rod 2404 is installed at the bottom of the head beam 22 inside the upper housing 10. The second flipping electric push rod 2404 extends and retracts, pushes and pulls the backrest connecting crank 2403, and drives the right backrest rotating shaft 2401 and the left backrest rotating shaft 2402 to rotate on the bearing 13 with a seat. The rotating shaft extends out of the outer side of the upper housing 10 and drives the clamping arm part 3 to rotate. The backrest part 1 and the bracket part 2, which are fixed on the clamping arm part 3, complete the flipping synchronously, realizing the independent adjustment of the backrest tilt angle and the bracket lifting angle.

[0037] Complete transfer procedure: Move the equipment to the bedside, adjust the overall height, and control the seat and backrest mechanisms to flip and open to a suitable posture; align the equipment with the outside of the elderly person's body, with the seat 401 flipping and extending under the elderly person's thighs, and the backrest 101 flipping to fit against the elderly person's back, while the two support sections provide auxiliary support for the elderly person's chest and shoulders; then, use the lifting mechanism to lift the elderly person off the bed, and control the machine to move and transfer them to a wheelchair or commode; once in place, lower the overall height, and then control the seat 401 and backrest 101 to flip and open in the opposite direction to complete the placement of the elderly person, and then remove the equipment; throughout the entire process, the seat 401 and backrest 101 can be independently adjusted in angle, allowing for real-time adjustment of the support posture according to the elderly person's physical condition, achieving safe and comfortable transfer.
