DETAILED DESCRIPTION

[0037] To make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0038] Please refer to Figures 1 to 12 The present application provides a technical scheme: a movable mechanical hand device for assisting the elderly to get on and off, comprising a multi-angle steering arm 1 and a support column 2 rotatably connected on the multi-angle steering arm 1, a placing seat body 3 is installed above the support column 2, and a groove corresponding to the elderly is arranged in the placing seat body 3.

[0039] The rotation connection design of 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 realize multi-angle free rotation within a range of 360 degrees, and through its driving of the support column 2, the placing seat body 3 above the support column 2 can be adjusted in direction according to actual needs. Whether it is to move the old people from the bed to the wheelchair or to adjust to a seat of different orientation, it can be easily realized, effectively avoiding the transfer difficulty caused by limited direction, facilitating the nursing staff to quickly and accurately transfer the old people to the target position according to the environmental layout, and improving the efficiency of nursing work.

[0040] The groove design in the placing seat body 3 corresponding to the old people fully considers the ergonomics principle and has good safety and comfort. The shape and size of the groove fit the body curve of the old people, and when the old people sit or lie on the placing seat body 3, the body can be effectively supported and fixed, reducing the risk of injury caused by shaking or collision during the movement.

[0041] A conveyor belt body 4 is arranged at the corresponding position of the inner wall bottom of the placing seat body 3, a conveying roller 5 is arranged in the conveyor belt body 4, and the conveyor belt body 4 is drivingly connected with the placing seat body 3 through the conveying roller 5;

[0042] Through the rotation of the conveying roller 5, the conveyor belt body 4 can be driven to run stably, which makes the movement of the old people on the placing seat body 3 more convenient. When it is needed to transfer the old people from the placing seat to the bed, wheelchair or other positions, the nursing staff does not need to move laboriously, but only needs to start the conveyor belt body 4, and the old people can move slowly along the conveying direction, greatly reducing the physical burden of the nursing staff and the risk of injury of the old people caused by improper manual handling.

[0043] A driving motor 6 is arranged at the bottom of the placing 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 is engaged with the gear on the conveying roller 5;

[0044] The driving motor 6 as the power core can accurately control the rotation speed and torque, and through the engagement transmission of the first driving wheel 7 and the gear of the conveying roller 5, the power is stably transmitted to the conveying roller 5, and then the conveyor belt body 4 is driven to run. Compared with the belt transmission and other modes, this mechanical engagement transmission mode has higher transmission efficiency and smaller power loss, which can ensure that the conveyor belt body 4 runs at a stable speed and power, avoids slipping, jamming and other situations, and provides reliable protection for the stable transfer of the old people.

[0045] 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;

[0046] The rotatable flap 8 on the conveying belt body 4 is connected by a hinge and can switch between horizontal and vertical states, greatly improving the convenience and safety of the mobile mechanical hand device. When the rotatable flap 8 is in a horizontal state, it can form a complete plane structure with the placing seat body 3 and the conveying belt body 4, expand the bearing area, and provide a more spacious and stable placing space for the elderly. When transferring the elderly to a bed or other location, the rotatable flap 8 in the horizontal state can seamlessly dock the target plane, making the sliding transfer process of the elderly more smooth, avoiding bumps or jamming caused by the difference in plane, and effectively reducing the risk of injury to the elderly.

[0047] When the rotatable flap 8 is in a vertical state, it can play a protective and limiting role. During the movement of the device, the upright rotatable flap 8 can prevent the elderly from accidentally falling, just like a guardrail to protect the safety of the elderly; when transferring the elderly from other locations to the placing seat body 3, the flap in the vertical state can also help guide the elderly to accurately position, making it convenient for nursing staff to operate.

[0048] The first assembly 9 is fixedly installed on the back of the rotatable flap 8, the fixed buckle 10 is arranged on the bottom of the placing seat body 3 near the rotatable flap 8, the self-adapting telescopic column 11 is movably installed in the fixed buckle 10, the movable clamping block 12 is arranged on one end of the self-adapting telescopic column 11 near the first assembly 9, and the limiting rotating block 13 is rotatably connected to the movable clamping block 12 and slidably installed in the first assembly 9.

[0049] The connection structure composed of the first assembly 9 on the back of the rotatable flap 8, the fixed buckle 10, the self-adapting telescopic column 11, the movable clamping block 12 and the limiting rotating block 13 on the bottom of the placing seat body 3 provides a solid guarantee for the stable operation of the rotatable flap. When the rotatable flap 8 is in a horizontal state, the self-adapting telescopic column 11 can automatically adjust the length according to the actual installation gap, push the movable clamping block 12 to accurately embed in the first assembly 9, and at this time the limiting rotating block 13 is slidably positioned in the first assembly 9, forming a firm clamping structure. This adaptive connection method not only ensures that the rotatable flap and the placing seat body are tightly combined, effectively disperses the pressure caused by the weight of the elderly, avoids loosening and shaking at the connection, but also prevents the rotatable flap from accidentally turning over during the movement of the device or the transfer of the elderly, ensuring the safety of the elderly.

[0050] When it is necessary to adjust the rotatable flap 8 to the vertical state, the nursing staff only needs to simply operate to separate the movable clamping block 12 from the first assembly 9, and the limiting rotating block 13 is unlocked, so that the rotatable flap can be easily rotated. Moreover, the adaptive telescopic column 11 is automatically retracted during the separation process, reducing structural interference, making the flap state switching more smooth and efficient. The whole connecting structure is designed ingeniously, which not only ensures the stability of the rotatable flap in different states, but also takes into account the convenience of operation, so that the mobile manipulator device performs more reliably and stably when assisting the elderly in moving, transferring and other operations, and brings a better use experience to the elderly and nursing staff.

[0051] The first installation groove 901 is provided on the first assembly 9, and is used for sliding guidance of the movable clamping block 12.

[0052] The second installation groove 902 is provided on the first installation groove 901, and is used for sliding guidance of the limiting rotating block 13.

[0053] The first installation groove 901 is specially designed for the movable clamping block 12, and its precise size and shape provide precise sliding guidance for the movable clamping block 12, so that the movable clamping block 12 can run smoothly along the fixed track when embedding and separating the first assembly 9, avoiding deviation, jamming and other situations. This not only ensures the close connection between the rotatable flap 8 and the placing seat body 3 in the horizontal state, but also maintains the stability of the connecting structure when the device bears the weight of the elderly and the vibration during movement, effectively disperses the pressure, and prevents the connection from loosening or the rotatable flap from accidentally turning over.

[0054] The sliding guidance of the limiting rotating block 13 by the second installation groove 902 is also crucial. When the movable clamping block 12 is embedded in the first installation groove 901, the limiting rotating block 13 slides into place along the second installation groove 902, forming a stable clamping with the first assembly 9, which further enhances the reliability of the connecting structure like double insurance. When it is necessary to switch the state of the rotatable flap 8, the limiting rotating block 13 can smoothly slide in the second installation groove 902, and quickly unlock the movable clamping block 12, making the operation of turning the flap from horizontal to vertical or vice versa more easy and efficient.

[0055] The limiting end cover 14 is arranged at the end of the adaptive telescopic column 11 away from the movable clamping block 12, and is used for limiting the movement of the adaptive telescopic column 11.

[0056] The limiting end cover 14 can effectively limit the movement range of the adaptive telescopic column 11, avoid it from disengaging from the fixed buckle 10 due to excessive displacement during telescoping, or colliding with or interfering with other components. When the rotatable flap 8 is connected or separated from the placement seat body 3, the limiting end cover 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 cover 14 can also protect the end of the adaptive telescopic column 11 to some extent, prevent it from being worn or impacted by the outside world, prolong the service life of the telescopic column, and thus ensure that the entire connection structure can function stably for a long time, providing a more solid foundation for the efficient use of the mobile manipulator device.

[0057] Two protective strips 15 are arranged on the placement seat body 3, and the two protective strips 15 are arranged at both ends of the conveyor belt body 4. The protective strips 15 are used to prevent the embedding of clothes.

[0058] The two protective strips 15 arranged on the placement seat body 3 are located at both ends of the conveyor belt body 4, and become an important supplement to the safety protection system of the device. During the movement of the old people with the help of the conveyor belt body 4, clothes may approach the edge of the conveyor belt due to inadvertent pulling or swinging. Once they are caught in the gap between the conveyor belt and the placement seat body 3, not only the clothes may be damaged, but also the old people may be injured due to the imbalance of the body caused by the pulling of the clothes. At the same time, the protective strips 15 can be made of soft and wear-resistant materials, which will not cause friction damage to the skin of the old people, and can maintain the protection performance for a long time, further improving the safety and reliability of the device during use, and making the old people and nursing staff more at ease.

[0059] A handrail 16 is arranged on the top of the placement seat body 3, and the handrail 16 is used for hand protection.

[0060] An inclined support plate 17 is arranged on the upper side of the placement seat body 3, and the inclined support plate 17 is used to assist the old people to get on and off.

[0061] Side edge fixing buckles 18 are fixedly installed on both sides of the rotatable flap 8, and insertion blocks 19 are movably installed in the side edge fixing buckles 18. Positioning plates 20 are fixedly installed on the insertion blocks 19, and the positioning plates 20 are movably installed on the placement seat body 3.

[0062] When the rotatable flap 8 is in a horizontal state, the insertion blocks 19 can be flexibly inserted into the side edge fixing buckles 18, and drive the positioning plates 20 to tightly engage on the placement seat body 3. The movable installation design of the positioning plates 20 and the placement seat body 3 enables the rotatable flap 8 to obtain stable support in the horizontal direction through precise groove or slide rail cooperation.

[0063] The top end of the support column 2 is externally provided with a circular mounting seat 21, the top of the support column 2 is fixedly installed with a support seat 22, the support seat 22 is fixedly installed at the bottom of the circular mounting seat 21, the circular mounting seat 21 is fixedly installed with an inner fixing ring 23, and the circular mounting seat 21 and the inner fixing ring 23 are connected with a rotatable ring 24 in a structure;

[0064] The circular mounting seat 21 externally provided at the top end of the support column 2, the fixedly installed support seat 22, the inner fixing ring 23 and the rotatable ring 24 constitute the core pivot of flexible steering of the device, the support seat 22 stably connects the support column 2 and the circular mounting seat 21, and provides a solid foundation for the whole top structure, the inner fixing ring 23 and the circular mounting seat 21 form an annular frame, and the rotatable ring 24 flexibly rotates therein, which provides the possibility for multi-angle steering of the placing seat body 3. When it is necessary to adjust the orientation of the old person to adapt to the bed or seat in different directions, the rotatable ring 24 can be driven by the driving device to realize smooth and accurate rotation. The structure design not only ensures the stability of the placing seat body 3 during steering to avoid shaking or jamming, but also effectively disperses the weight pressure generated when the placing seat body 3 bears the old person through reasonable mechanical distribution, and further enhances the reliability of the whole device.

[0065] The rotatable ring 24 is fixedly installed at the bottom of the placing seat body 3.

[0066] The top of the support seat 22 is fixedly installed with a stepping motor 25, the output shaft of the stepping motor 25 is fixedly installed with a second driving wheel 26, the bottom of the placing seat body 3 is fixedly installed with a transmission gear 27, and the second driving wheel 26 is drivingly connected with the rotatable ring 24 through the transmission gear 27.

[0067] The second driving wheel 26 and the transmission gear 27 are engaged, and the transmission gear 27 is engaged with the rotatable ring 24.

[0068] Working principle:

[0069] First step: through the work of the multi-angle steering arm 1, the structure on the support column 2 is driven to move to assist the old person to lift and move, the output shaft of the stepping motor 25 drives the second driving wheel 26 to rotate, the rotation of the second driving wheel 26 drives the transmission gear 27 to rotate, the rotation of the transmission gear 27 drives the rotatable ring 24 to rotate, the rotatable ring 24 rotates in the structure composed of the circular mounting seat 21 and the inner fixing ring 23, and the rotatable ring 24 drives the placing seat body 3 to rotate on the support column 2 when rotating, the rotation of the placing seat body 3 drives the old person on the placing seat body 3 to rotate slowly, so as to steer the old person and conveniently place the old person on the bed in different directions.

[0070] Second step: the old man is placed on the conveyor belt body 4 on the placing seat body 3 by the aid of the inclined support plate 17, and the comfort of the old man sitting on the structure composed of the placing seat body 3 and the conveyor belt body 4 is ensured by the presence of the handrail 16. After the old man moves to the appropriate position, the rotatable flap 8 needs to be rotated to form a horizontal structure with the placing seat body 3. When the rotatable flap 8 is rotated, the first assembly 9 on the back of the rotatable flap 8 is also rotated. When the first assembly 9 is rotated, the structure composed of the movable clamping block 12 and the limiting rotating block 13 moves in the structure composed of the first installation slot 901 and the second installation slot 902. When the first assembly 9 is rotated, the self-adapting telescopic column 11 moves in the fixed buckle 10. When the self-adapting telescopic column 11 moves, the limiting rotating block 13 moves and rotates in the second installation slot 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 placing 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 move on the side fixed buckle 18. The side fixed buckle 18 is clamped on the placing seat body 3 to realize the fixation of the rotatable flap 8 after being horizontal. The first drive wheel 7 is driven to rotate by the driving motor 6, the transmission roller 5 is driven to rotate by the rotation of the first drive wheel 7, the conveyor belt body 4 is driven to move by the rotation of the transmission roller 5, and the old man is driven to move on the placing seat body 3 by the movement of the conveyor belt body 4, thereby assisting the old man to move to the bed at a high or bottom position.
