A fixed buckle is arranged at the bottom of the placing seat body near one side of the rotatable flap. An adaptive telescopic column is movably installed in the fixed buckle. A movable clamping block is arranged at one end of the adaptive telescopic column close to the first assembly. A limiting rotating block is rotatably connected to the movable clamping block, and the limiting rotating block is slidably installed in the first assembly.

[0006] Preferably, a first installation groove is formed in the first assembly, and the first installation groove is used for guiding the sliding of the movable clamping block. A second installation groove is formed in the first installation groove, and the second installation groove is used for guiding the sliding of the limiting rotating block.

[0007] Preferably, a limiting end cover is arranged at one end of the adaptive telescopic column far from the movable clamping block, and the limiting end cover is used for limiting the movement of the adaptive telescopic column.

[0008] Preferably, two protective belts are arranged on the placing seat body, and the two protective belts are arranged at both ends of the conveyor belt body, and the protective belts are used to prevent the embedding of clothes.

[0009] Preferably, a handrail is arranged at the top of the placing seat body, and the handrail is used for protecting the hand.

[0010] Preferably, an inclined support plate is arranged on the upper person side of the placing seat body, and the inclined support plate is used to assist the elderly to get on and off.

[0011] Preferably, side fixing buckles are fixedly installed on both sides of the rotatable flap. An insertion block is movably installed in the side fixing buckle. A positioning plate is fixedly installed on the insertion block, and the positioning plate is movably installed on the placing seat body.

[0012] Preferably, a circular mounting seat is arranged outside the top end of the support column. A support seat is fixedly installed at the top of the support column. The support seat is fixedly installed at the bottom of the circular mounting seat. An inner fixing ring is fixedly installed in the circular mounting seat. A rotatable ring is rotatably connected in the structure formed by the circular mounting seat and the inner fixing ring. The rotatable ring is fixedly installed at the bottom of the placing seat body.

[0013] Preferably, a stepping motor is fixedly installed at the top of the support seat. A second driving wheel is fixedly installed on the output shaft of the stepping motor. A transmission gear is fixedly installed at the bottom of the placing seat body. The second driving wheel is in transmission connection with the rotatable ring through the transmission gear.

[0014] Preferably, the second driving wheel meshes with the transmission gear, and the transmission gear meshes with the rotatable ring.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. After the elderly person moves to a suitable position, the rotatable flap needs to be rotated to form a horizontal structure with the placement seat body. By rotating the first driving wheel, the conveyor roller is driven to rotate. The rotation of the conveyor roller drives the movement of the conveyor belt body, and the movement of the conveyor belt body drives the elderly person to move on the placement seat body, so as to assist the elderly person to move to a high or low bed. The rotatable flap can form a horizontal structure with the placement seat body, which can be flexibly adjusted according to the actual situation to adapt to beds of different heights and meet the needs of the elderly to move from different positions to the bed.

[0016] 2. The output shaft of the stepping motor drives the second driving wheel to rotate. By the rotation of the transmission gear, the rotatable ring is driven to rotate. When the rotatable ring rotates, it drives the placement seat body to rotate on the support column. The rotation of the placement seat body drives the elderly person on the placement seat body to rotate slowly, so as to turn the elderly person. The stepping motor can achieve precise angle control, so that the placement seat body drives the elderly person to rotate slowly, stably and precisely. In this way, according to the actual needs, the elderly person can be accurately turned to a suitable angle, avoiding the inconvenience or safety hazards caused by inaccurate turning angles, without the need for the nursing staff to manually turn the elderly person with great effort, reducing the physical consumption and working intensity of the nursing staff. At the same time, it also reduces the possibility of accidental injury to the elderly caused by improper operation during the manual turning process, improving the safety and comfort of nursing.

Detailed implementation manners

[0030] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts fall within the scope of protection of the present invention.

[0031] Please refer to Figures 1 to 12 , the present invention provides a technical solution: a mobile manipulator device for assisting the elderly to get on and off, including a multi-angle steering arm 1 and a support column 2 rotatably connected to the multi-angle steering arm 1. A placement seat body 3 is installed above the support column 2, and a groove body corresponding to the elderly is provided in the placement seat body 3; The rotational connection design between the multi-angle steering arm 1 and the support column 2 greatly improves the flexibility and applicability of the device. The multi-angle steering arm 1 can achieve multi-angle free rotation within a range of 360 degrees. By driving the support column 2 to rotate, the placement seat body 3 above the support column 2 can adjust its direction according to actual needs. Whether it is moving the elderly from the bedside to a wheelchair or adjusting to a seat in a different orientation, it can be easily achieved, effectively avoiding the transfer difficulties caused by limited direction, facilitating the nursing staff to quickly and accurately transfer the elderly to the target position according to the environmental layout, and improving the efficiency of nursing work.

[0032] The groove design corresponding to the elderly in the placement seat body 3 fully considers the principles of ergonomics and has good safety and comfort. The shape and size of the groove fit the body curves of the elderly. When the elderly sit or lie on the placement seat body 3, their bodies can be effectively supported and fixed, reducing the risk of injury due to shaking or collision during the movement process.

[0033] At the corresponding position at the bottom of the inner wall of the placement seat body 3, a conveyor belt body 4 is provided. A conveyor roller 5 is arranged inside the conveyor belt body 4, and the conveyor belt body 4 is drivingly connected to the placement seat body 3 through the conveyor roller 5; Through the rotation of the conveyor roller 5, the conveyor belt body 4 can be driven to run smoothly, which makes the movement of the elderly on the placement seat body 3 more convenient. When it is necessary to transfer the elderly from the placement seat to positions such as a bed or a wheelchair, there is no need for the nursing staff to move laboriously. Just start the conveyor belt body 4, and the elderly can slowly move along the conveying direction, greatly reducing the physical burden of the nursing staff and at the same time reducing the risk of the elderly being injured due to improper manual handling.

[0034] A driving motor 6 is arranged at the bottom of the placement seat body 3. A first driving wheel 7 is arranged on the output shaft of the driving motor 6, and the first driving wheel 7 meshes with the gear on the conveyor roller 5; As the power core, the driving motor 6 can accurately control the rotation speed and torque. Through the meshing transmission between the first driving wheel 7 and the gear of the conveyor roller 5, the power is stably transmitted to the conveyor roller 5, and then the conveyor belt body 4 is driven to operate. This mechanical meshing transmission method has higher transmission efficiency and less power loss compared with belt transmission and other methods, and can ensure that the conveyor belt body 4 runs at a stable speed and force, avoiding situations such as slipping and jamming, providing a reliable guarantee for the smooth transfer of the elderly.

[0035] A rotatable flap 8 is rotatably connected to the conveyor belt body 4 through a hinge, and the rotatable flap 8 has a horizontal state and a vertical state; The rotatable flap 8 rotatably connected to the conveyor belt body 4 by hinges greatly improves the usability and safety of the mobile manipulator device by switching between horizontal and vertical states. When the rotatable flap 8 is in the horizontal state, it can form a complete flat structure with the placement seat body 3 and the conveyor belt body 4, expanding the bearing area and providing a more spacious and stable placement space for the elderly. When transferring the elderly to the bed or other positions, the rotatable flap 8 in the horizontal state can seamlessly dock with the target plane, making the process of the elderly sliding along the conveyor belt smoother, avoiding jolts or jams caused by plane drops, and effectively reducing the risk of the elderly being injured. When the rotatable flap 8 is in the vertical state, it can play a role in protection and positioning. During the movement of the device, the erected rotatable flap 8 can prevent the elderly from accidentally slipping, protecting the safety of the elderly like a guardrail; when transferring the elderly from other positions to the placement seat body 3, the flap in the vertical state can also help guide the elderly to be accurately positioned, facilitating the operation of the nursing staff.

[0036] A first assembly 9 is fixedly installed on the back of the rotatable flap 8. A fixed buckle 10 is provided on the bottom of the placement seat body 3 near the rotatable flap 8. An adaptive telescopic column 11 is movably installed in the fixed buckle 10. A movable clamping block 12 is provided at one end of the adaptive telescopic column 11 close to the first assembly 9. A limiting rotating block 13 is rotatably connected to the movable clamping block 12, and the limiting rotating block 13 is slidably installed in the first assembly 9.

[0037] The connection structure composed of the first assembly 9 on the back of the rotatable flap 8, the fixed buckle 10 at the bottom of the placement seat body 3, the adaptive telescopic column 11, the movable clamping block 12 and the limiting rotating block 13 provides a solid guarantee for the stable operation of the rotatable flap. When the rotatable flap 8 is in the horizontal state, the adaptive telescopic column 11 can automatically adjust its length according to the actual installation gap, pushing the movable clamping block 12 to accurately embed into the first assembly 9. At this time, the limiting rotating block 13 slides in place in the first assembly 9 to form a firm clamping structure. This adaptive connection method not only ensures the tight combination of the rotatable flap and the placement seat body, effectively disperses the pressure brought by the weight of the elderly, and avoids loosening and shaking at the connection, but also prevents the rotatable flap from accidentally flipping during the movement of the device or the process of conveying the elderly, ensuring the safety of the elderly.

[0038] When it is necessary to adjust the rotatable flap 8 to the vertical state, the caregiver only needs to perform a simple operation to separate the movable block 12 from the first assembly 9. The limit rotation block 13 is then unlocked, and the rotatable flap can be easily rotated. Moreover, the adaptive telescopic column 11 will automatically contract during the separation process, reducing structural interference and making the flap state switching smoother and more efficient. The entire connection structure is ingeniously designed, ensuring both the stability of the rotatable flap in different states and the convenience of operation, making the performance of the mobile manipulator device more reliable and stable when assisting the elderly in moving, transferring, etc., and bringing a better user experience to the elderly and caregivers.

[0039] A first installation groove 901 is formed on the first assembly 9, and the first installation groove 901 is used for the sliding guidance of the movable block 12. A second installation groove 902 is formed on the first installation groove 901, and the second installation groove 902 is used for the sliding guidance of the limit rotation block 13.

[0040] The first installation groove 901 is specifically designed for the movable block 12. Its precise size and shape provide precise sliding guidance for the movable block 12, enabling the movable block 12 to run smoothly along a fixed track when being inserted into and separated from the first assembly 9, avoiding situations such as deviation and jamming. This not only ensures the tight connection between the rotatable flap 8 and the placement seat body 3 in the horizontal state but also maintains the stability of the connection structure when the device bears the weight of the elderly and the vibration during the movement process, effectively dispersing the pressure and preventing the loosening of the connection or the accidental flipping of the rotatable flap. The sliding guidance function of the second installation groove 902 for the limit rotation block 13 is equally crucial. When the movable block 12 is inserted into the first installation groove 901, the limit rotation block 13 slides into place along the second installation groove 902 and forms a firm engagement with the first assembly 9, further enhancing the reliability of the connection structure like a double insurance. When it is necessary to switch the state of the rotatable flap 8, the limit rotation block 13 can slide smoothly in the second installation groove 902, cooperating with the movable block 12 to quickly unlock, making the operation of flipping the flap from horizontal to vertical or vice versa easier and more efficient.

[0041] A limit end cap 14 is provided at one end of the adaptive telescopic column 11 away from the movable block 12, and the limit end cap 14 is used for limiting the movement of the adaptive telescopic column 11.

[0042] The limiting end cap 14 can effectively limit the movement range of the adaptive telescopic column 11, preventing it from disengaging from the fixed buckle 10 due to excessive displacement during the telescopic process, or colliding and interfering with other components. When the rotatable flap 8 is connected to or separated from the placement seat body 3, the limiting end cap 14 ensures that the adaptive telescopic column 11 always moves within a controllable range, maintaining the stability and integrity of the connection structure. In addition, the limiting end cap 14 can also protect the end of the adaptive telescopic column 11 to a certain extent, preventing it from being worn and impacted by the outside world, extending the service life of the telescopic column, thereby ensuring that the entire connection structure functions stably for a long time and providing a more solid foundation for the efficient use of the mobile manipulator device.

[0043] Two protective belts 15 are provided on the placement seat body 3, and the two protective belts 15 are arranged at both ends of the conveyor belt body 4. The protective belt 15 is used to prevent the embedding of clothes.

[0044] The two protective belts 15 provided on the placement seat body 3, located at both ends of the conveyor belt body 4, become an important supplement to the device safety protection system. During the movement of the elderly with the help of the conveyor belt body 4, clothes may accidentally be pulled or swing close to the edge of the conveyor belt. Once caught in the gap between the conveyor belt and the placement seat body 3, it may not only damage the clothes, but also cause the elderly to lose balance due to the pulling of the clothes, resulting in accidental injuries. At the same time, the protective belt 15 can be made of a soft and wear-resistant material, which will not cause frictional damage to the elderly's skin and can maintain the protective performance for a long time, further improving the safety and reliability during the use of the device and making the elderly and caregivers more at ease.

[0045] A handrail 16 is provided on the top of the placement seat body 3, and the handrail 16 is used for hand protection.

[0046] An inclined support plate 17 is provided on the upper person side of the placement seat body 3, and the inclined support plate 17 is used to assist the elderly in getting on and off.

[0047] Side fixing buckles 18 are fixedly installed on both sides of the rotatable flap 8. An insertion block 19 is movably installed in the side fixing buckle 18. A positioning plate 20 is fixedly installed on the insertion block 19, and the positioning plate 20 is movably installed on the placement seat body 3.

[0048] When the rotatable flap 8 is in a horizontal state, the insertion block 19 can be flexibly inserted into the side fixing buckle 18, driving the positioning plate 20 to tightly engage with the placement seat body 3. The movable installation design of the positioning plate 20 and the placement seat body 3, through precise slot or slide rail cooperation, enables the rotatable flap 8 to obtain stable support in the horizontal direction.

[0049] A circular mounting seat 21 is arranged outside the top of the support column 2, a supporting seat 22 is fixedly installed on the top of the support column 2, the supporting seat 22 is fixedly installed on the bottom of the circular mounting seat 21, an inner fixing ring 23 is fixedly installed inside the circular mounting seat 21, and a rotatable ring 24 is rotatably connected inside the structure composed of the circular mounting seat 21 and the inner fixing ring 23; The circular mounting seat 21, the fixedly mounted supporting seat 22, the inner fixed ring 23 and the rotatable ring 24 arranged outside the top of the supporting column 2 constitute the core hub for the flexible steering of the device. The supporting seat 22 firmly connects the supporting column 2 and the circular mounting seat 21, providing a solid foundation for the entire top structure. The inner fixed ring 23 and the circular mounting seat 21 form an annular frame, in which the rotatable ring 24 flexibly rotates, providing the possibility for the multi-angle steering of the placing seat body 3. When it is necessary to adjust the orientation of the elderly to adapt to beds or chairs in different directions, the rotatable ring 24 can achieve smooth and precise rotation under the drive of the driving device. This structural design not only ensures the stability of the placing seat body 3 during the steering process, avoiding shaking or jamming, but also effectively disperses the weight pressure generated by the placing seat body 3 when carrying the elderly through reasonable mechanical distribution, further enhancing the reliability of the entire device.

[0050] The rotatable ring 24 is fixedly mounted on the bottom of the placement seat body 3 .

[0051] A stepper motor 25 is fixedly mounted on the top of the support seat 22 , a second driving wheel 26 is fixedly mounted on the output shaft of the stepper motor 25 , a transmission gear 27 is fixedly mounted on the bottom of the placement seat body 3 , and the second driving wheel 26 is connected to the rotatable ring 24 through the transmission gear 27 .

[0052] The second driving wheel 26 is meshed with the transmission gear 27 , and the transmission gear 27 is meshed with the rotatable ring 24 .

[0053] Working principle: The first step: through the operation of the multi-angle steering arm 1, the structure on the support column 2 is driven to move to assist the elderly in lifting and moving. The second driving wheel 26 is driven to rotate by the output shaft of the stepping motor 25. The transmission gear 27 is driven to rotate by the rotation of the second driving wheel 26. The rotatable ring 24 is driven to rotate by the rotation of the transmission gear 27. The rotatable ring 24 rotates in the structure composed of the circular mounting seat 21 and the inner fixed ring 23. When the rotatable ring 24 rotates, it drives the placement seat body 3 to rotate on the support column 2. The rotation of the placement seat body 3 drives the elderly on the placement seat body 3 to rotate slowly, so as to turn the elderly, so as to facilitate the placement of the elderly on beds in different orientations.

[0054] Step 2: The elderly are placed on the conveyor belt body 4 on the placement seat body 3 with the assistance of the inclined support plate 17. With the presence of the armrest 16, the comfort of the elderly sitting on the structure composed of the placement seat body 3 and the conveyor belt body 4 is ensured. After the elderly move to a suitable position, the rotatable flap 8 needs to be rotated to form a horizontal structure with the placement seat body 3. When the rotatable flap 8 rotates, the first assembly 9 on the back of the rotatable flap 8 also rotates accordingly. When the first assembly 9 rotates, it drives the structure composed of the movable block 12 and the limit rotating block 13 to move within the structure composed of the first installation groove 901 and the second installation groove 902. When the first assembly 9 rotates, the self-adaptive telescopic column 11 will move adaptively within the fixed buckle 10. When the self-adaptive telescopic column 11 moves, the limit rotating block 13 will move and rotate within the second installation groove 902 to adapt to the rotation of the rotatable flap 8 and the first assembly 9. When the rotatable flap 8 is in a horizontal state, the placement seat body 3 and the rotatable flap 8 form a horizontal structure. When the rotatable flap 8 is horizontal, the positioning plate 20 and the insertion block 19 are pushed to move on the side fixing buckle 18, and the side fixing buckle 18 is clamped on the placement seat body 3 to achieve the fixation after the rotatable flap 8 is horizontal. The first driving wheel 7 is driven to rotate by the driving motor 6. The rotation of the first driving wheel 7 drives the conveying roller 5 to rotate. The rotation of the conveying roller 5 drives the conveyor belt body 4 to move. The movement of the conveyor belt body 4 drives the elderly to move on the placement seat body 3 to assist the elderly to move to a high or low bed position.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
