Description

Technical Field

[0001] This utility model belongs to the field of medical rehabilitation technology, specifically relating to an ergonomic assistive device. Background Technology

[0002] With the rapid development of ergonomic technology, assistive devices are increasingly widely used in fields such as medical rehabilitation, physical enhancement, and industrial material handling. These devices assist human joints or muscles through mechanical structures, aiming to reduce the user's exercise load and improve mobility.

[0003] However, existing assistive devices only have a single fixation structure for the hip or abdomen, resulting in poor fixation. The reaction force after the drive components on the assistive device move the legs is concentrated on a single fixation point, which can easily cause soft tissue compression injuries. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, this utility model provides an ergonomic assistive device to address the technical problems in the background.

[0005] This utility model provides the following technical solution: an ergonomic assistive device, comprising:

[0006] A hip connection assembly includes a mounting part and two connecting parts rotatably connected to both ends of the mounting part in a first direction. The ends of the two connecting parts away from the mounting part are connected by a limiting structure to enclose the user's hips.

[0007] A flexible support, the flexible support comprising a first support portion rotatably connected to the mounting portion in a second direction and at least one second support portion rotatably connected to the top of the first support portion in a third direction;

[0008] An abdominal connection assembly is connected via the second support portion of the flexible bracket. The abdominal connection assembly includes an abdominal belt body and connectors disposed at both ends of the abdominal belt body. The connectors are used to enclose the abdominal belt body around the user's abdomen.

[0009] A drive assembly, which is mounted on the mounting portion of the hip connection assembly;

[0010] A leg connection assembly, which is connected to the drive assembly via a connecting rod;

[0011] The first direction, the second direction, and the third direction correspond to three mutually perpendicular directions in the spatial coordinate system.

[0012] Compared with existing technologies, the beneficial effects of this invention are as follows: During the operation of the assistive device, the hip connecting component and the abdominal connecting component cooperate with each other, replacing the traditional single fixed component. This prevents the reaction force after the drive component moves the legs from being concentrated on a single fixed part, thereby reducing soft tissue compression damage. When the wearer bends forward or extends their back backward, the second support part rotates relative to the first support part based on a third direction, following the wearer's forward or backward flexion or extension movements. When the wearer twists their back to the left or right, the first support part rotates relative to the mounting part based on a second direction, following the wearer's left and right twisting movements. This design makes the flexible support flexible, enabling multi-degree-of-freedom dynamic fit to the waist and hips, adapting to complex movements such as walking and bending, and improving wearing comfort and movement flexibility. The segmented rotating structure of the flexible support (first support part and second support part) combined with the abdominal connecting component can distribute the lumbar support force to the hips and abdomen, avoiding local pressure concentration, which conforms to ergonomic principles.

[0013] Furthermore, the connecting part is an arc-shaped plate structure, and a buffer layer is provided on the inner side of the connecting part.

[0014] Furthermore, the limiting structure is a locking structure.

[0015] Furthermore, the abdominal binder body is made of elastic and breathable fabric.

[0016] Furthermore, the rotary connections corresponding to the first direction, the second direction, and the third direction include a movable slot, a movable block adapted to the movable slot, and a universal joint.

[0017] Furthermore, a limiting block extends from one side of the movable block, and the limiting block extends out of the limiting groove of the movable groove to limit the rotation angle of the movable block relative to the movable groove.

[0018] Furthermore, the connector at one end of the abdominal binder body includes a locking block, and the connector at the other end includes a plurality of slots arranged in a row. The slots are adapted to the locking block so that the abdominal binder body forms rings of different sizes.

[0019] Furthermore, a support component is provided between the abdominal connecting component and the hip connecting component. The support component includes a first limiting bag disposed on the abdominal belt body, a second limiting bag disposed on the connecting part, and an elastic support rod. The two ends of the elastic support rod are respectively sleeved in the first limiting bag and the second limiting bag, so that the abdominal connecting component and the hip connecting component form an integral support.

[0026] To facilitate understanding of this utility model, a more complete description of it will be provided below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] Please see Figure 1 and Figure 2 The diagram illustrates an ergonomically based assistive device according to an embodiment of this utility model, comprising:

[0030] A hip connection assembly includes a mounting part and two connecting parts rotatably connected to both ends of the mounting part in a first direction. The ends of the two connecting parts away from the mounting part are connected by a limiting structure to enclose the user's hips.

[0031] A flexible support, the flexible support comprising a first support portion rotatably connected to the mounting portion in a second direction and at least one second support portion rotatably connected to the top of the first support portion in a third direction;

[0032] An abdominal connection assembly is connected via the second support portion of the flexible bracket. The abdominal connection assembly includes an abdominal belt body and connectors disposed at both ends of the abdominal belt body. The connectors are used to enclose the abdominal belt body around the user's abdomen.

[0033] A drive assembly, which is mounted on the mounting portion of the hip connection assembly;

[0034] A leg connection assembly, which is connected to the drive assembly via a connecting rod;

[0035] The first direction, the second direction, and the third direction correspond to three mutually perpendicular directions in the spatial coordinate system.

[0036] The process of wearing the assistive device is as follows: First, the hip connection component is limited to the user's hip position by the limiting structure. Then, the abdominal connection component is limited to the user's abdomen by two connectors. At this time, the position of the flexible bracket corresponds to the position of the user's spine. Next, the leg connection component is limited to the user's legs, and the leg connection component is connected to the drive component by the connecting rod to complete the wearing of the assistive device.

[0037] During operation, the hip and abdominal connection components work together, replacing the traditional single fixed component. This prevents the reaction force from the drive component's leg movement from concentrating on a single fixed point, thus reducing soft tissue compression damage. When the wearer bends forward or extends their back backward, the second support rotates relative to the first support in a third direction, following the wearer's flexion or extension movements. When the wearer twists their back left or right, the first support rotates relative to the mounting part in a second direction, following the wearer's left and right twists. This design makes the flexible support flexible, enabling multi-degree-of-freedom dynamic conformation to the waist and hips, adapting to complex movements such as walking and bending, improving wearing comfort and movement flexibility. The segmented rotating structure of the flexible support (first and second support components) combined with the abdominal connection component distributes lumbar support force to the hips and abdomen, avoiding localized pressure concentration, conforming to ergonomic principles.

[0038] The two connecting parts rotate relative to the mounting part based on a first direction, so that the hip connecting assembly can be adapted to wearers with different waist sizes.

[0039] Furthermore, the connecting part is an arc-shaped plate structure, and a buffer layer is provided on the inner side of the connecting part. The arc-shaped plate connecting part conforms to the curve of the human buttocks, and together with the inner buffer layer, it reduces the friction and pressure of hard materials on the skin, enhancing the comfort of wearing for a long time.

[0040] In this embodiment, the limiting structure is a locking structure. The locking limiting structure simplifies the wearing process of the hip connection component, while providing a stable closure effect to prevent the component from accidentally coming loose during exercise.

[0041] In this embodiment, the abdominal binder body is made of elastic and breathable fabric. The abdominal binder body made of elastic and breathable fabric balances support and breathability, avoiding stuffiness, adapting to different users' abdominal size variations, and improving versatility.

[0042] Please see Figure 3 and Figure 4 Furthermore, the rotary connections corresponding to the first direction, the second direction, and the third direction include a movable slot, a movable block adapted to the movable slot, and a universal joint. Even further, a limiting block extends from one side of the movable block, extending out of the limiting slot of the movable slot to limit the rotation angle of the movable block relative to the movable slot. The cooperative design of the movable slot, movable block, and universal joint, combined with the control of the rotation angle by the limiting block, ensures multi-directional adjustment capability while avoiding structural failure or injury to the user due to excessive joint torsion, thus improving the safety and durability of the device.

[0043] Furthermore, the connector at one end of the abdominal binder body includes a locking block, and the connector at the other end includes multiple slots arranged in a row. The slots are adapted to the locking block to allow the abdominal binder body to form rings of different sizes. The adaptation structure of the locking block and multiple slots allows the abdominal binder body to be quickly adjusted in circumference, suitable for users of different body types, and has high adjustment precision, accurately matching individual needs.

[0044] Furthermore, a support assembly is provided between the abdominal connection assembly and the hip connection assembly. This support assembly includes a first limiting pocket on the abdominal belt body, a second limiting pocket on the connecting portion, and an elastic support rod. Both ends of the elastic support rod are respectively fitted into the first and second limiting pockets, so that the abdominal connection assembly and the hip connection assembly form an integrated support. The elastic support rod connects the abdominal and hip components through the limiting pockets, forming an overall lumbar support system, distributing the force on the lumbar spine and assisting the user in maintaining correct posture.

[0045] In summary, the ergonomic assistive device described in the above embodiments of this utility model is worn as follows: First, the hip connecting component is positioned at the user's hip using a limiting structure. Then, the abdominal connecting component is positioned at the user's abdomen using two connecting parts. At this time, the position of the flexible support corresponds to the position of the user's spine. Next, the leg connecting component is positioned at the user's legs, and the leg connecting component is connected to the drive component via a connecting rod, thus completing the wearing of the assistive device.

[0046] During operation, the hip and abdominal connection components work together, replacing the traditional single fixed component. This prevents the reaction force from the drive component's leg movement from concentrating on a single fixed point, thus reducing soft tissue compression damage. When the wearer bends forward or extends their back backward, the second support rotates relative to the first support in a third direction, following the wearer's flexion or extension movements. When the wearer twists their back left or right, the first support rotates relative to the mounting part in a second direction, following the wearer's left and right twists. This design makes the flexible support flexible, enabling multi-degree-of-freedom dynamic conformation to the waist and hips, adapting to complex movements such as walking and bending, improving wearing comfort and movement flexibility. The segmented rotating structure of the flexible support (first and second support components) combined with the abdominal connection component distributes lumbar support force to the hips and abdomen, avoiding localized pressure concentration, conforming to ergonomic principles.
