Description

Technical Field

[0001] This utility model relates to the field of intelligent nursing technology, and in particular to a rotating device and a nursing robot. Background Technology

[0002] Nursing robots, as commonly used intelligent devices in nursing homes, can use their built-in programs and robot heads to identify the user's status and needs, thereby providing timely assistance to the user.

[0003] In the existing technology, nursing robots include a torso and a head. The head is directly fixed to the torso through fixed joints. During use, the torso drives the head to move, thereby adjusting the orientation and posture of the head so that the head can face the user.

[0004] However, when users are sitting or lying down, their heads are difficult to change angle accordingly, which leads to problems in recognizing users' needs and resulting in poor service performance. Utility Model Content

[0005] The purpose of this invention is to provide a rotating device and a nursing robot, which solves the problem that the adjustment angle of the robot head in the prior art is very limited, making it difficult to accurately identify the user's needs and resulting in poor service.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] In a first aspect, this utility model provides a rotating device, which includes:

[0008] First support;

[0009] The second bracket is fixed to the first bracket;

[0010] A rotating shaft is rotatably connected to the second bracket and used to fix and mount the robot head.

[0011] The driving component is slidably connected to the first bracket;

[0012] The transmission assembly has one end connected to the rotating shaft and the other end connected to the driving component;

[0013] An adjustment component is disposed on the first bracket and fixedly connected to the drive component to tension the transmission component.

[0014] Optionally, the adjustment component includes:

[0015] The mounting base is slidably connected to the first bracket, and the driving component is fixedly mounted on the mounting base;

[0016] An adjustment seat is provided on the first bracket;

[0017] An adjustment part is inserted through the adjustment seat and rotatably connected to the adjustment seat. One end of the adjustment part passes through the adjustment seat and is threadedly connected to the mounting base.

[0018] Optionally, the mounting base is provided with a first locking part, and the first locking screw is fixedly connected to the first bracket.

[0019] Optionally, the adjustment seat is slidably connected to the first bracket.

[0020] Optionally, the adjusting seat is provided with a second locking part, which can abut against the first bracket.

[0021] Optionally, the first support includes:

[0022] A fixing rod, the second bracket being fixed to the fixing rod;

[0023] An adjusting rod is fixedly mounted on the fixed rod and extends along an axis perpendicular to the rotating shaft. The adjusting rod is located at the middle of the axis of the rotating shaft. The driving component and the adjusting assembly are both mounted on the adjusting rod.

[0024] Optionally, the second support includes:

[0025] The vertical rod is fixedly installed on the first bracket;

[0026] A horizontal bar is fixedly mounted on the vertical bar, and the rotating shaft is rotatably connected to the horizontal bar;

[0027] The support rod has one end fixedly connected to the vertical rod and the other end fixedly connected to the horizontal rod.

[0028] Optionally, the rotating device further includes:

[0029] A reinforcing rib is fixedly installed at the connection between the first bracket and the second bracket.

[0030] Optionally, the transmission assembly includes:

[0031] The drive wheel is fixedly installed at the output end of the drive component;

[0032] Driven wheel, fixedly mounted on the rotating shaft;

[0033] A drive belt is fitted onto the driving pulley and the driven pulley.

[0034] Secondly, this utility model also provides a nursing robot, characterized in that it includes:

[0035] The rotating device as described in any one of the first aspects;

[0036] The robot's head is mounted on the rotating device.

[0037] The beneficial effects of this utility model are:

[0038] Firstly, when the user's posture changes, the robot head can detect the change and activate the drive mechanism. The drive mechanism then drives the transmission component, which, under the tension of the adjusting component, drives the transmission shaft to rotate synchronously, thus causing the robot head to rotate precisely. When the robot head detects a position corresponding to the user's posture, it can stop the drive mechanism, thereby stopping the rotation. Therefore, in use, this rotating device allows for precise control of the robot head's rotation angle and speed by starting and stopping the drive mechanism and adjusting the tension of the transmission component. This ensures the robot head can flexibly adjust its angle to accurately identify the user's needs, effectively improving service quality.

[0039] Secondly, when in use, the robot's head can rotate flexibly via a rotating device to adjust its angle according to the user's posture, thereby ensuring that the robot's head can accurately identify the user's needs and quickly provide the corresponding assistance, thus effectively improving the service effect.

[0053] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0054] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0055] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0056] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0057] This utility model discloses a rotating device and a nursing robot.

[0058] Reference Figures 1 to 4The rotating device includes a first support 1, a second support 2, a rotating shaft 3, a driving component 4, a transmission assembly 5, and an adjusting assembly 6. The second support 2 is fixed to the first support 1; the rotating shaft 3 is rotatably connected to the second support 2 and is used to fix the robot head 7; the driving component 4 is slidably connected to the first support 1; one end of the transmission assembly 5 is connected to the rotating shaft 3, and the other end is connected to the driving component 4; the adjusting assembly 6 is disposed on the first support 1 and fixedly connected to the driving component 4 to tension the transmission assembly 5.

[0059] Specifically, both the first bracket 1 and the second bracket 2 are made of aluminum alloy material through milling, drilling, tapping, and surface oxidation to form a frame structure. The first bracket 1 is horizontal and can be fixed to the robot's body or to other platforms. The second bracket 2 is three-dimensional and extends vertically. The upper end of the second bracket 2 is rotatably connected to a rotating shaft 3 through a bearing. The bearing can both lock the position and allow the rotating shaft 3 to rotate. The specific type of bearing can be selected according to the actual installation space, and this utility model does not limit it in this regard.

[0060] The robot head 7 is fixedly equipped with a connecting flange 71, which is sleeved on and fixedly connected to the rotating shaft 3. The connecting flange 71 can be made of carbon steel plate. The robot head 7 has built-in programs and sensors, which can track and scan the user in real time to obtain the user's needs. The drive component 4 can be a servo motor or a self-locking motor, etc., and the transmission component 5 can be a belt drive or a chain sensor, etc. The transmission component 5 is adjusted by the adjustment component 6 to maintain the tension of the transmission component 5.

[0061] When the user's posture changes, the robot head 7 detects the change and activates the drive unit 4. The drive unit 4 then drives the transmission component 5. Under the tension of the adjustment component 6, the transmission component 5 drives the transmission shaft to rotate synchronously, thereby causing the robot head 7 to rotate precisely. When the robot head 7 detects a position corresponding to the user's posture, it stops the drive unit 4, thus stopping the rotation. Therefore, in use, this rotating device allows for precise control of the rotation angle and speed of the robot head 7 by starting and stopping the drive unit 4 and by adjusting the tension of the transmission component 5 through the adjustment component 6. This ensures that the robot head 7 can flexibly adjust its angle to accurately identify the user's needs, thereby effectively improving service quality.

[0062] Optionally, the adjustment assembly 6 includes a mounting base 61, an adjustment base 62, and an adjustment part 63. The mounting base 61 is slidably connected to the first bracket 1, and the driving member 4 is fixedly installed on the mounting base 61; the adjustment base 62 is disposed on the first bracket 1; the adjustment part 63 passes through the adjustment base 62 and is rotatably connected to the adjustment base 62, and one end of the adjustment part 63 passing through the adjustment base 62 is threadedly connected to the mounting base 61.

[0063] Specifically, the mounting base 61 is inserted into the first bracket 1, and the two can slide relative to each other along a direction perpendicular to the axis of the rotating shaft 3. The driving component 4 is fixed to the side of the mounting base 61 by screws, and one end of the transmission component 5 is fixedly connected to the output end of the driving component 4. The adjusting base 62 is disposed on the first bracket 1, and the two can be fixedly connected or slidably engaged. An adjusting part 63 is provided on the adjusting base 62. The adjusting part 63 is elongated and its extension direction is parallel to the sliding direction of the mounting base 61. The adjusting part 63 and the adjusting base 62 can be rotatably connected by bearings, and a threaded hole is opened on the side of the mounting base 61 facing the adjusting base 62. At least part of the adjusting part 63 is threaded into the threaded hole. In this embodiment, the adjusting part 63 is a screw; in other embodiments, the adjusting part 63 can also be a screw rod or other structure.

[0064] By providing the mounting base 61, the drive component 4 can be fixed on the mounting base 61 to form a sliding engagement with the first bracket 1. By providing the adjusting base 62 and the adjusting part 63, the mounting base 61 can be slid by turning the adjusting part 63, thereby moving one end of the drive component 4 and the transmission assembly 5. This allows for easy adjustment of the distance between the two ends of the transmission assembly 5, ensuring that the transmission assembly 5 can maintain a tensioned state. Moreover, this adjustment method can reduce direct contact with the transmission assembly 5, thereby reducing wear and tear on the transmission assembly 5 during operation and effectively extending its service life.

[0065] Optionally, the mounting base 61 is provided with a first locking part 64, and the first locking screw is fixedly connected to the first bracket 1.

[0066] Specifically, the inner wall of the mounting base 61 is slidably fitted with the first bracket 1, and a waist-shaped hole is provided through the side of the mounting base 61. The waist-shaped hole extends along the sliding direction of the mounting base 61, and a first locking part 64 is inserted into the waist-shaped hole. The first locking part 64 can be a locking screw and is threaded to the first bracket 1.

[0067] This sliding fit ensures that the mounting base 61 will not tilt during sliding. Once the mounting base 61 is in place, the first locking part 64 can be screwed on, causing its end wall to press against the outer wall of the mounting base 61, thereby fixing the mounting base 61 to the first bracket 1 and improving the connection strength between the mounting base 61 and the first bracket 1. The first locking part 64 can be provided as a single unit, or one unit can be provided on each of the opposite sides of the mounting base 61.

[0068] Optionally, the adjusting seat 62 is slidably connected to the first bracket 1.

[0069] Specifically, the adjusting seat 62 is inserted into the first bracket 1, and the adjusting seat 62 can slide along the sliding direction of the mounting seat 61, so that the adjusting seat 62 and the mounting seat 61 can be adjusted in a large range on the first bracket 1 to ensure that the transmission component 5 can be effectively tensioned.

[0070] Optionally, the adjusting seat 62 is provided with a second locking part 65, which can abut against the first bracket 1.

[0071] Specifically, the second locking part 65 passes through the adjusting seat 62, and the second locking part 65 can also be a locking screw, which is threadedly connected to the adjusting seat 62. One end of the second locking part 65 passing through the adjusting seat 62 can abut against the side wall of the first bracket 1, thereby fixing the adjusting seat 62 to the first bracket 1. This improves the connection strength between the adjusting seat 62 and the first bracket 1, thereby ensuring better stability of the adjusting assembly 6 when fixed to the first bracket 1, and ensuring better tensioning effect of the adjusting assembly 6.

[0072] Optionally, the first bracket 1 includes a fixed rod 11 and an adjusting rod 12. The second bracket 2 is fixed to the fixed rod 11; the adjusting rod 12 is fixedly disposed on the fixed rod 11 and extends along the axis perpendicular to the rotating shaft 3, the adjusting rod 12 is located at the middle of the axis of the rotating shaft 3, and the driving component 4 and the adjusting assembly 6 are both disposed on the adjusting rod 12.

[0073] Specifically, two fixed rods 11 are arranged opposite each other, and an adjusting rod 12 is arranged between the two fixed rods 11. The extension directions of the fixed rods 11 and the extension directions of the adjusting rod 12 are perpendicular to each other, so that the first bracket 1 is in the shape of an I-beam. The extension direction of the adjusting rod 12 is perpendicular to the axis of the rotating shaft 3, and the adjusting rod 12 is located at the middle position of the rotating shaft 3. This allows both the adjusting component 6 and the transmission component 5 to be located at the middle position of the rotating shaft 3, so that the middle of the rotating shaft 3 bears the driving force of rotation. The two ends of the rotating shaft 3 are rotatably connected to the second bracket 2 by bearings, thereby ensuring that the rotating shaft 3 is subjected to uniform force during rotation and effectively extending the service life of the rotating shaft 3.

[0074] Optionally, the second support 2 includes a vertical rod 21, a horizontal rod 22, and a support rod 23. The vertical rod 21 is fixedly mounted on the first support 1; the horizontal rod 22 is fixedly mounted on the vertical rod 21, and the rotating shaft 3 is rotatably connected to the horizontal rod 22; one end of the support rod 23 is fixedly connected to the vertical rod 21, and the other end is fixedly connected to the horizontal rod 22.

[0075] Specifically, the vertical rod 21 extends vertically, with its lower end fixedly connected to the top wall of the fixing rod 11 of the first bracket 1, and its upper end fixedly connected to one end of the horizontal rod 22. The fixing method can be welding, bonding, or screw connection. The horizontal rod 22 extends horizontally and its extension direction is perpendicular to the axis of the rotating shaft 3. Two vertical rods 21 and two horizontal rods 22 can be arranged opposite each other, and reinforcing rods can be installed between the two vertical rods 21 and the two horizontal rods 22. A support rod 23 is installed between the vertical rods 21 and the horizontal rods 22, extending at an angle. The support rod 23, the vertical rods 21, and the horizontal rods 22 form a triangular frame to improve the connection strength between the vertical rods 21 and the horizontal rods 22. This ensures that the second bracket 2 has a high load-bearing capacity, facilitating the installation of robot heads 7 of different weights.

[0076] Optionally, the rotating device further includes a reinforcing rib 8. The reinforcing rib 8 is fixedly disposed at the connection between the first support 1 and the second support 2.

[0077] Specifically, multiple reinforcing ribs 8 can be provided, and multiple ribs can be fixedly provided at the connection between the first bracket 1 and the second bracket 2 to improve the connection strength between the two. Inside the first bracket 1 and inside the second bracket, multiple reinforcing ribs 8 can be fixedly provided at the connection between the fixing rod 11 and the adjusting rod 12, and at the connection between the horizontal bar 22 and the vertical bar 21. The fixing method can be screw connection, bonding or welding, etc., to improve the overall load-bearing capacity.

[0078] Optionally, the transmission assembly 5 includes a driving pulley, a driven pulley, and a transmission belt. The driving pulley is fixedly mounted on the output end of the drive component 4; the driven pulley is fixedly mounted on the rotating shaft 3; and the transmission belt is sleeved on the driving pulley and the driven pulley.

[0079] Specifically, the driving wheel is fixed to the output end of the driving component 4 via a coupling, while the driven wheel is sleeved on the rotating shaft 3 and fixedly connected to the rotating shaft 3. Both the driving wheel and the driven wheel are synchronous pulleys, and the transmission belt is a synchronous belt. With this driving component 4 driving the driving wheel to rotate, the driving wheel can drive the synchronous belt to rotate synchronously, and the synchronous belt can drive the rotating shaft 3 to rotate synchronously via the driven wheel.

[0080] The nursing robot includes a robot head 7 and a rotating device as described in the above embodiment. The robot head 7 is disposed on the rotating device.

[0081] When in use, the robot head 7 can rotate flexibly via a rotating device to adjust its angle according to the user's posture, thereby ensuring that the robot head 7 can accurately identify the user's needs and quickly provide the corresponding assistance, thus effectively improving the service effect.

[0082] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
