Description

Technical Field

[0001] The present invention relates to the technical field of living supplies transfer appliances for disabled elderly people, and specifically relates to a living supplies transfer system for disabled elderly people. Background Art

[0002] Disabled elderly people, generally speaking, are those who cannot take care of themselves and rely on care. It is a common syndrome among the elderly. Due to the impairment of self-care functions and limited activities, the daily life of disabled elderly people requires a transfer system that can help them transfer living supplies. Through this transfer system, disabled elderly people can use living supplies without the help of caregivers, thereby improving the quality of life of disabled elderly people.

[0003] However, the existing transfer systems have great defects in the use process. The existing transfer systems are generally installed beside the beds of disabled elderly people, unable to move flexibly, unable to fetch living supplies from a relatively far distance, with a small scope of action. At the same time, before use, it is necessary to manually sort out the living supplies required by the disabled elderly people one by one, and the use is not convenient. The existing transfer systems cannot be adjusted in height, are relatively large in size, and are not conducive to storage. At the same time, the inability to adjust the height makes the transfer systems that can be adapted and installed on beds limited, reducing the adaptability of the transfer systems. At the same time, due to the inability to adjust the height, when a disabled elderly person sits up from a lying position or lies down from a sitting position, the system cannot well adapt to the disabled elderly person. The existing transfer systems can only play the role of delivering items to the side of the disabled elderly person. For severely disabled elderly people when using living items, they cannot be assisted beside, and cannot help the disabled elderly person use living supplies safely. Summary of the Invention

[0004] In view of the problems in the prior art, the present invention provides a living supplies transfer system for disabled elderly people.

[0005] The technical solution adopted by the present invention to solve its technical problems is as follows: A daily necessities transfer system for disabled elderly people, comprising a walking component, a lifting component, a conveying component, a lifting platform and a clamping component. The top of the walking component is respectively installed with the lifting component and the lifting platform. The conveying component is installed on the top of the lifting component. The clamping component is installed on the top of the lifting platform. By setting the walking component, the system can walk. By moving the system, the system can transfer daily necessities from any position to the side of the disabled elderly. In this way, on the one hand, the system can transfer items over a longer distance. On the other hand, in cooperation with the clamping component, the system can pick up daily necessities from different positions. Furthermore, before the system is used, it is not necessary to specifically sort out the daily necessities used by the disabled elderly. By setting the lifting platform, the height of the clamping component can be adjusted so that the clamping component can pick up daily necessities from higher places. By using the lifting component, the height of the conveying component can be adjusted so that the height of the conveying component can be more adapted to the height of the bed where the disabled elderly are located. At the same time, it is more convenient for the disabled elderly to pick up the daily necessities transferred by the system. Whether the disabled elderly are lying down or sitting up, the conveying component can well adapt to the disabled elderly. By using the lifting component and the lifting platform, the overall height of the system can be adjusted. By adjusting the overall height of the system, on the one hand, by reducing the overall height of the system, the volume of the device is smaller. On the other hand, by reducing the overall height of the system and cooperating with the walking component, the system can walk, and thus the system can pass through a lower space. At the same time, the system can also be moved and used in a more complex environment. Among them, the conveying component includes a first-stage bottom rail, a second-stage bottom rail and a tray. The first-stage bottom rail is horizontally arranged. The top of the first-stage bottom rail is horizontally movably matched with the second-stage bottom rail. The tray is movably matched on the top of the second-stage bottom rail. By setting the first-stage bottom rail and the second-stage bottom rail to move the tray, on the one hand, the conveying component can send the tray out over a longer distance, and thus the action range of the conveying component is larger. By making the action range of the conveying component larger, when the system transfers daily necessities over a shorter distance, the whole system does not need to move again, and thus the frequency and number of overall movements of the system can be effectively reduced. On the other hand, the second-stage bottom rail and the tray move simultaneously, and thus the position of the tray can be adjusted more quickly. The clamping component includes a fixed seat, a first force arm and an electric gripper. The top of the fixed seat is rotatably matched with a rotating plate. A fifth motor for driving the rotation of the rotating plate is vertically installed on the fixed seat. The top of the rotating plate is installed with a rotating seat in a "U" shape structure through bolts. One end of the first force arm is hinged to the rotating seat. A sixth motor for driving the rotation of the first force arm is horizontally installed on one side of the rotating seat. The end of the first force arm away from the rotating seat is hinged to a second force arm. A seventh motor for driving the rotation of the second force arm is horizontally installed inside the second force arm near the first force arm. The end of the second force arm away from the first force arm is hinged to a third force arm.An eighth motor for driving the third force arm to rotate is horizontally installed on the inner side of one end of the second force arm away from the first force arm. A steering plate is fixed to the end of the third force arm away from the second force arm. The electric gripper is rotatably fitted on the side of the steering plate away from the third force arm. A ninth motor for driving the electric gripper to rotate is installed on the side of the steering plate close to the third force arm. By assisting the disabled elderly through the clamping component, it can avoid danger when the disabled elderly use daily necessities, providing a guarantee for the safe use of daily necessities by the disabled elderly. By setting the ninth motor, the angle of the electric gripper can be rotated, facilitating the electric gripper to better clamp items.

[0008] Preferably, the lifting component includes a second motor, a first electric cylinder and a mounting block. The second motor is vertically installed on the top of the walking component. The first electric cylinder is vertically arranged on the top of the second motor through a rotating shaft. A first push rod is vertically arranged at the top of the first electric cylinder. The mounting block is fixed to the top of the first push rod. The first bottom rail is welded and fixed to the top of the mounting block. By driving the first push rod by the first electric cylinder, the first push rod pushes the mounting block, enabling the lifting component to achieve the lifting adjustment function.

[0009] Preferably, a first slide rail is horizontally welded to the top of the first bottom rail. Pulley wheels are rotatably fitted at both ends of the top of the first bottom rail. A transmission belt is sleeved on the two pulley wheels. A third motor for driving one of the pulley wheels to rotate is horizontally installed at one end of the first bottom rail. A first slider slidably engaged with the first slide rail is welded to the bottom of the second bottom rail. The second bottom rail is movably fitted on the top of the first bottom rail through the first slider. A connecting block connected to the transmission belt is welded to the bottom of the second bottom rail. By the cooperation of the first slider and the first slide rail, the second bottom rail moves more smoothly, and thus the tray moves more smoothly.

[0010] Preferably, slide rods are horizontally fixed on both sides of the top of the secondary bottom rail. A lead screw is horizontally rotatably fitted between the two slide rods at the top of the secondary bottom rail. A fourth motor for driving the lead screw to rotate is horizontally installed at one end of the secondary bottom rail. Two slide rings and a nut are welded to the bottom of the tray. The two slide rings are respectively sleeved on the two slide rods, and the two slide rings are respectively in sliding fit with the two slide rods. The nut is in threaded fit with the lead screw. By setting the sliding fit between the slide rings and the slide rods, the tray moves more smoothly.

[0011] Preferably, stoppers are welded at the four corners of the top of the tray. The four stoppers are all in an "L" shape. By setting the stoppers, the daily necessities placed on the tray are not easily dropped.

[0012] Preferably, the lifting platform includes a bottom plate, a support plate and a lifting plate. The bottom plate is installed on the top of the walking assembly through bolts. The support plate is vertically welded to the top of the bottom plate. A second slide rail is vertically welded on one side of the support plate. A push plate is welded to the bottom of the lifting plate. A second slider that is in sliding fit with the second slide rail is welded on the side of the push plate close to the support plate.

[0013] Preferably, anti-collision radars are installed on the periphery of the walking assembly. Cameras that can turn are installed on both sides of the top of the walking assembly. Position sensors are installed at the ends of the conveying component and the clamping component. A PLC controller is installed at the bottom of the walking assembly. The surrounding environment is surveyed by the cameras. The walking assembly of the system is controlled by the PLC controller to make the system move. The PLC controller controls the steering of the system through the data transmitted by the anti-collision radars to avoid the system colliding with other objects. The position signals of the daily necessities are transmitted through the position sensors, so that the PLC controller controls the system to move towards the daily necessities, and the conveying component and the clamping component are controlled through the precise position signals of the daily necessities to pick up and convey the objects.

[0014] Preferably, the usage method of the daily necessities transfer system for disabled elderly people specifically includes the following steps:

[0015] Step 1: Driven by the first motor, the walking wheels rotate. By rotating the walking wheels, the transfer system moves, and the system is moved to the daily necessities required by the disabled elderly. Driven by the fifth motor, the direction of the clamping component is rotated so that the clamping component faces the daily necessities. Driven by the sixth motor, the first lever arm rotates. Driven by the seventh motor, the second lever arm rotates. Driven by the eighth motor, the third lever arm rotates. By rotating the first lever arm, the second lever arm and the third lever arm, the electric gripper is moved to the daily necessities to be transferred, and the daily necessities are clamped by the electric gripper.

[0016] Step 2: The daily necessities are clamped onto the tray of the conveying component by the clamping component. The system is moved to the side of the disabled elderly through the walking component. Driven by the third motor, the pulley rotates. By rotating the pulley, the transmission belt drives, and the transmission belt drives the secondary bottom rail to move. Driven by the fourth motor, the lead screw rotates. By rotating the lead screw, the nut moves, and the nut drives the tray to move. By moving the secondary bottom rail and the tray, the tray is moved to the side of the elderly. At the same time, driven by the second motor, the lifting component rotates, and then drives the conveying component to rotate. By rotating the conveying component, the disabled elderly with movable hands can reach the daily necessities on the tray.

[0017] Step 3: For the disabled elderly with poor mobility, the daily necessities on the tray are clamped by the clamping component, and the disabled elderly are directly assisted to use the daily necessities through the clamping component.

[0018] Advantages of the present invention:

[0019] (1) In the present invention, by setting the walking component, the system can walk, thereby improving the convenience of the system's mobile transportation. By moving the system, the system can transfer daily necessities from any position to the side of the disabled elderly. On the one hand, this enables the system to transfer items over a longer distance, thus increasing the scope of the system's function. On the other hand, in cooperation with the clamping component, the system can pick up daily necessities from different positions. Therefore, before using the system, it is not necessary to specifically organize the daily necessities used by the disabled elderly, thereby improving the convenience of using the system. By using four first motors to drive the four walking wheels respectively, on the one hand, the power of the transfer system is stronger, thus improving the system's ability to carry items. At the same time, the system can operate more smoothly and stably on sloping ground, thereby improving the system's applicability to the use site. On the other hand, the system's steering control is more flexible, thus improving the flexibility of the transfer system's movement. By setting omnidirectional wheels at the bottom of the walking component, the system turns more smoothly, thereby improving the flexibility of the system's steering adjustment.

[0020] (2) In the present invention, by setting up a lifting platform, the height of the clamping component is adjusted, enabling the clamping component to pick up daily necessities at higher positions, thereby further expanding the scope of application of the system. By using a lifting component, the height of the conveying component is adjusted, making the height of the conveying component more adaptable to the height of the bed where the disabled elderly are located, thus improving the compatibility of the system. At the same time, it enables the disabled elderly to more conveniently access the daily necessities conveyed by the system. Whether the disabled elderly are lying down or sitting up, the conveying component can well adapt to them. By using the lifting component and the lifting platform, the overall height of the system can be adjusted. By adjusting the overall height of the system, on the one hand, by reducing the overall height of the system, the volume of the device becomes smaller, making the storage of the system more convenient. On the other hand, by reducing the overall height of the system and cooperating with the walking component to make the system move, the system can then pass through smaller spaces, further improving the flexibility of the system's movement and enabling the system to be used in more complex environments, thereby enhancing the adaptability of the system to the usage environment.

[0021] (3) In the present invention, by setting up a primary bottom rail and a secondary bottom rail to move the tray, on the one hand, it enables the conveying component to send the tray out a longer distance, thus expanding the scope of action of the conveying component. By expanding the scope of action of the conveying component, when the system conveys daily items over a short distance, the overall system does not need to move again, effectively reducing the frequency and number of overall system movements, and thus saving the energy consumed by the system to a certain extent. On the other hand, the secondary bottom rail and the tray move simultaneously, enabling the position of the tray to be adjusted more quickly, thereby improving the usage efficiency of the system. By setting up a clamping component to assist the disabled elderly with extremely poor walking ability and help them use daily necessities, the convenience of the disabled elderly using the system is improved. At the same time, by using the clamping component to assist the disabled elderly, it can prevent the disabled elderly from being in danger when using daily necessities, providing a guarantee for the safe use of daily necessities by the disabled elderly, thus enhancing the safety and reliability of the system's use.

Detailed implementation manners

[0033] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0034] Such as Figures 1-9As shown in the figure, a daily necessities transfer system for disabled elderly people according to the present invention includes a walking component 1, a lifting component 2, a conveying component 3, a lifting platform 4 and a clamping component 5. The lifting component 2 and the lifting platform 4 are respectively installed on the top of the walking component 1. The conveying component 3 is installed on the top of the lifting component 2, and the clamping component 5 is installed on the top of the lifting platform 4. By setting the walking component 1, the system can walk, thereby improving the convenience of the system for mobile transportation. By moving the system, the system can transfer daily necessities from any position to the side of the disabled elderly people. On the one hand, the system can transfer items over a longer distance, thereby increasing the working range of the system. On the other hand, in cooperation with the clamping component 5, the system can pick up daily necessities from different positions, so that before the system is used, it is not necessary to specially organize the daily necessities used by the disabled elderly people, thereby improving the convenience of using the system. By setting the lifting platform 4, the height of the clamping component 5 can be adjusted, so that the clamping component 5 can pick up daily necessities from higher places, thereby further increasing the working range of the system. By using the lifting component 2, the height of the conveying component 3 can be adjusted, so that the height of the conveying component 3 can be more adapted to the height of the bed where the disabled elderly people are located, thereby improving the compatibility of the system. At the same time, it makes it more convenient for the disabled elderly people to pick up the daily necessities transferred by the system. Whether the disabled elderly people are lying down or sitting up, the conveying component 3 can well adapt to the disabled elderly people. By using the lifting component 2 and the lifting platform 4, the overall height of the system can be adjusted. By adjusting the overall height of the system, on the one hand, by reducing the overall height of the system, the volume of the device is smaller, so that the system can be more conveniently stored. On the other hand, by reducing the overall height of the system and cooperating with the walking component 1 to make the system walk, the system can pass through a smaller space, thereby further improving the flexibility of the system for mobile walking. At the same time, it also enables the system to be used for mobile use in a more complex environment, thereby improving the adaptability of the system to the use environment. Among them, the conveying component 3 includes a first-stage bottom rail 301, a second-stage bottom rail 306 and a tray 310. The first-stage bottom rail 301 is horizontally arranged. The second-stage bottom rail 306 is horizontally movably matched with the top of the first-stage bottom rail 301. The tray 310 is movably matched with the top of the second-stage bottom rail 306. By setting the first-stage bottom rail 301 and the second-stage bottom rail 306 to move the tray 310, on the one hand, the conveying component 3 can send the tray 310 out over a longer distance, so that the working range of the conveying component 3 is larger. By making the working range of the conveying component 3 larger, when the system transfers daily necessities over a shorter distance, the whole system does not need to move again, so that the frequency and number of overall movements of the system can be effectively reduced, thereby saving the energy consumed by the system to a certain extent. On the other hand, the second-stage bottom rail 306 and the tray 310 move simultaneously, so that the position of the tray 310 can be adjusted faster, thereby improving the use efficiency of the system.The clamping assembly 5 includes a fixed seat 501, a first force arm 505, and an electric gripper 513 (model: 2f-140).

A ninth motor 512 for driving the rotation of the electric gripper 513 is installed on the side of the steering plate 511 near the third force arm 509. By using the clamping assembly 5 to assist the disabled elderly, it can avoid danger when the disabled elderly use daily necessities, provide a guarantee for the safe use of daily necessities by the disabled elderly, and thus improve the safety and reliability of the system. By setting the ninth motor 512, the angle of the electric gripper 513 can be rotated, which is convenient for the electric gripper 513 to better grip items.

Driven by the sixth motor 506, the first force arm 505 is rotated. Driven by the seventh motor 508, the second force arm 507 is rotated. Driven by the eighth motor 510, the third force arm 509 is rotated. By rotating the first force arm 505, the second force arm 507 and the third force arm 509, the electric gripper 513 is moved to the side of the daily necessities to be conveyed, and the daily necessities are clamped by the electric gripper 513.

[0045] Step 2: Use the clamping component 5 to clamp the daily necessities onto the tray 310 of the conveying component 3. Move the system to the side of the disabled elderly through the walking component 1. Drive the pulley 303 to rotate through the third motor 305. Through the rotation of the pulley 303, drive the transmission belt 304 to transmit power. The transmission belt 304 drives the secondary bottom rail 306 to move. Drive the lead screw 308 to rotate through the fourth motor 309. Through the rotation of the lead screw 308, move the nut 313. The nut 313 drives the tray 310 to move. By moving the secondary bottom rail 306 and the tray 310, move the tray 310 to the side of the elderly. At the same time, drive the lifting component 2 to rotate through the second motor 201, and then drive the conveying component 3 to rotate. Through the rotation of the conveying component 3, the disabled elderly with movable hands can reach the daily necessities on the tray 310;

[0046] Step 3: For the disabled elderly with poor mobility, use the clamping component 5 to pick up the daily necessities on the tray 310, and directly assist the disabled elderly to use the daily necessities through the clamping component 5.

[0047] During use, first, driven by the first motor 102, the walking wheels 101 rotate. By rotating the walking wheels 101, the transfer system moves, and the system is moved to the daily necessities needed by the disabled elderly. Driven by the fifth motor 503, the direction of the clamping component 5 is rotated so that the clamping component 5 faces the daily necessities. Driven by the sixth motor 506, the first lever 505 is rotated. Driven by the seventh motor 508, the second lever 507 is rotated. Driven by the eighth motor 510, the third lever 509 is rotated. By rotating the first lever 505, the second lever 507 and the third lever 509, the electric gripper 513 is moved to the daily necessities to be transferred. The daily necessities are clamped by the electric gripper 513. By setting the walking component 1, the system can walk, thus improving the convenience of the system's movement and transportation. By moving the system, the system can transfer the daily necessities from any position to the side of the disabled elderly. On the one hand, the system can transfer items over a longer distance, thus increasing the working range of the system. On the other hand, in cooperation with the clamping component 5, the system can pick up daily necessities from different positions. Therefore, before the system is used, it is not necessary to specifically organize the daily necessities used by the disabled elderly, thus improving the convenience of using the system. By using four first motors 102 to drive the four walking wheels 101 respectively, on the one hand, the power of the transfer system is stronger, thus improving the ability of the transfer system to carry items. At the same time, the system can move more smoothly on the sloping ground, thus improving the applicability of the system to the use site. On the other hand, the steering control of the system is more flexible, thus improving the flexibility of the transfer system's movement. By setting omnidirectional wheels 104 at the bottom of the walking component 1, the system turns more smoothly, thus improving the flexibility of the system's steering adjustment. Then, the daily necessities are clamped by the clamping component 5 onto the tray 310 of the conveying component 3. Through the walking component 1, the system is moved to the side of the disabled elderly. Driven by the third motor 305, the pulley 303 rotates. By rotating the pulley 303, the transmission belt 304 is driven to move. The transmission belt 304 drives the secondary bottom rail 306 to move. Driven by the fourth motor 309, the lead screw 308 rotates. By rotating the lead screw 308, the nut 313 moves. The nut 313 drives the tray 310 to move. By moving the secondary bottom rail 306 and the tray 310, the tray 310 is moved to the side of the elderly. At the same time, driven by the second motor 201, the lifting component 2 rotates, and then drives the conveying component 3 to rotate. By rotating the conveying component 3, the disabled elderly with movable hands can reach the daily necessities on the tray 310. By setting the lifting platform 4, the height of the clamping component 5 is adjusted so that the clamping component 5 can clamp the daily necessities at a higher position, thus further increasing the working range of the system. By using the lifting component 2, the height of the conveying component 3 is adjusted so that the height of the conveying component 3 can be more adapted to the height of the bed where the disabled elderly are located.Thus, the compatibility of the system is improved. At the same time, it enables the disabled elderly to more conveniently access the daily necessities delivered by the system. Whether the disabled elderly are lying down or sitting up, the transfer component 3 can well adapt to the disabled elderly. By using the lifting component 2 and the lifting platform 4, the overall height of the system can be adjusted. By adjusting the overall height of the system, on the one hand, by reducing the overall height of the system, the volume of the device becomes smaller, thus making the storage of the system more convenient. On the other hand, by reducing the overall height of the system and cooperating with the walking component 1, the system can walk, and then the system can pass through smaller spaces, further improving the flexibility of the system's movement and walking. At the same time, it also enables the system to be used for movement in more complex environments, thus improving the adaptability of the system to the use environment. Finally, for the disabled elderly with poor mobility, the daily necessities on the tray 310 are picked up by the clamping component 5, and the disabled elderly are directly assisted by the clamping component 5 to use the daily necessities. By setting the first-level bottom rail 301 and the second-level bottom rail 306, the tray 310 is moved. On the one hand, the transfer component 3 can send the tray 310 farther, and then the range of action of the transfer component 3 is larger. By making the range of action of the transfer component 3 larger, when the system transfers daily items over a short distance, the whole system does not need to move again, thus effectively reducing the frequency and number of times of the overall movement of the system, and thus being able to save the energy consumed by the system to a certain extent. On the other hand, the second-level bottom rail 306 and the tray 310 move simultaneously, and then the position of the tray 310 can be adjusted faster, thus improving the efficiency of the system. By setting the clamping component 5 to assist the disabled elderly with extremely poor walking ability and help the disabled elderly use daily necessities, the convenience of the disabled elderly using the system is improved. At the same time, by assisting the disabled elderly through the clamping component 5, the risk of the disabled elderly using daily items can be avoided, which provides a guarantee for the safe use of daily items by the disabled elderly, thus improving the safety and reliability of the system.
