Technical Field
[0001] This utility model relates to the field of bionic hand technology, specifically a retractable and retractable bionic working hand device. Background Technology
[0002] Bionic working hands are mechanical devices that integrate bionics, mechanical engineering and intelligent control technology. By imitating the multi-degree-of-freedom joint structure and motion logic of human or animal hands, and with the help of a drive system, they can realize working functions such as grasping, carrying and fine operation. They are widely used in medical rehabilitation, such as functional compensation for the disabled, industrial automation and special environment detection. The receiving cavity is the core connection carrier between the bionic working hand and the user's residual limb. It is usually customized according to the three-dimensional contour of the residual limb. Its inner side fits tightly with the residual limb to ensure comfort and stability, while its outer side is fixed to the wrist or elbow module of the bionic working hand through a standardized mechanical interface. It is responsible for transmitting the motion signals of the residual limb to the bionic working hand to drive its movement. Currently, most bionic hand receivers use rigid rubber sealing rings for protection, which cannot adapt to the contour changes of the residual limb caused by muscle activity and daily deformation. This can easily create blind spots in the gaps, allowing rainwater, dust, and other impurities to enter the receiver. This can not only cause equipment malfunctions such as internal circuit short circuits and joint transmission component jamming, shortening the service life, but also allow impurities to come into direct contact with the residual limb skin. This can easily induce redness, swelling, allergies, or even infection, especially for users with sensitive skin or scars, affecting the safety of use. Utility Model Content
[0003] The purpose of this invention is to provide a retractable and retractable bionic hand device to solve the problem in the prior art where most existing bionic hand receiving cavity and bionic hand connection protection uses rigid rubber sealing rings, which cannot adapt to the contour changes of the residual limb caused by muscle activity and daily deformation. This easily creates blind spots in the gaps, allowing rainwater, dust and other impurities to enter the receiving cavity. This may not only cause equipment failures such as internal circuit short circuits and joint transmission component jamming, shortening the service life, but also allow impurities to directly contact the residual limb skin. Especially for users with sensitive skin or scars, this can easily induce redness, swelling, allergies or even infection, affecting the safety of use.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a retractable and retractable bionic working hand device, including a bionic hand, a receiving cavity, and a connecting ring, wherein a protective component is provided inside the receiving cavity, and an auxiliary component is provided inside the receiving cavity; The protective component includes a silicone airbag, which is fixedly connected to the inner wall of the connecting ring. An air pump is fixedly connected to the outer surface of the connecting ring, and an air outlet pipe is provided inside the air pump. The end of the air outlet pipe away from the air pump is located inside the silicone airbag. The auxiliary components include multiple air outlets, each with a pressure valve inside. An air inlet pipe is fixedly connected to one side of the outer surface of the air pump, and a filter plate is installed inside the air inlet pipe.
[0005] Preferably, the connecting ring is fixedly connected to one side of the outer surface of the receiving cavity, and the silicone airbag is disposed inside the receiving cavity.
[0006] Preferably, a plurality of limiting posts are fixedly connected to one side of the outer surface of the connecting ring, and a limiting plate is fixedly connected to the side of the plurality of limiting posts away from the connecting ring.
[0007] Preferably, the bionic hand through-connecting ring is disposed inside the receiving cavity.
[0008] Preferably, the plurality of air outlets are arranged in a circumferential array inside the silicone airbag.
[0009] Preferably, the silicone airbag is made of medical-grade liquid silicone, and the plurality of air outlets are made of medical-grade ABS plastic.
[0010] Compared with the prior art, the beneficial effects achieved by this utility model are: Firstly, when used by a person with disabilities, the receiving cavity is placed over the limb, and then the bionic hand is inserted through the connecting ring into the receiving cavity to complete the connection. Next, a suction pump on one side of the connecting ring is activated to draw gas from the outside. The gas enters the pump through an inlet pipe, and during the suction process, the outside air is filtered by a filter plate. The gas drawn in by the pump is then introduced into the silicone airbag through an outlet pipe, causing the silicone airbag to inflate. The silicone airbag is positioned inside the connecting ring and the receiving cavity. When the silicone airbag inflates, a limiting plate restricts its maximum expansion range. Through this technical solution, the silicone airbag, upon inflation, can tightly fit the connection gap between the receiving cavity and the connecting ring. Compared to traditional rubber rings, its flexible material can adapt to the irregular contours of the residual limb, such as the uneven surfaces formed by scars or muscle atrophy, avoiding... To avoid sealing dead spots due to shape mismatch, the bionic hand's protective properties are improved. The flexible padding layer formed by the inflated silicone airbag can isolate the edge of the receiving cavity from direct contact with the residual limb skin, reducing friction and pressure between the two during use, such as gripping and limb movement, thus reducing the risk of residual limb skin abrasion and indentation, and indirectly improving long-term wearing comfort. Secondly, the filter plate in the air intake tube can intercept dust, pollen, hair and other impurities in the air, preventing such pollutants from entering the silicone airbag or receiving cavity with the air intake, preventing the silicone airbag from being affected by the accumulation of impurities, and preventing impurities from contacting the residual limb skin and causing problems such as allergies and folliculitis. In addition, the silicone airbag protects the connection between the receiving cavity and the bionic hand from rain or dust. When the bionic hand is not in use, the receiving cavity can be disconnected from the bionic hand and the silicone airbag can be deflated for storage.
[0011] Secondly, in this invention, when the silicone airbag inflates to the maximum range of the limiting plate, the air pump continues to intake air. At this time, the excess gas breaks through the pressure valves inside multiple air outlets and is discharged through the air outlets. The gas is blown into the receiving cavity through the air outlets. Through the above technical solution, after the excess gas is blown into the receiving cavity through the air outlets, an airflow circulation can be formed between the residual limb and the inner wall of the receiving cavity, directly carrying away the heat generated by the metabolism of the residual limb, while accelerating the evaporation of sweat and preventing sweat from accumulating inside the receiving cavity. This not only relieves the feeling of stuffiness, but also reduces the irritation of sweat to the skin of the residual limb, reducing problems such as eczema and dermatitis caused by sweat soaking. Sweat can cause the skin of the residual limb to irritate the skin of the receiving cavity. The inner wall of the receiving cavity can become sticky, potentially causing skin traction damage when putting on or taking off the receiving cavity. Airflow circulation can keep the inner wall of the receiving cavity dry, reducing stickiness, improving the smoothness of wearing the device, and reducing the risk of secondary skin damage. At the same time, the filter plate filters impurities in the air, preventing impurities from contaminating the skin of the residual limb and preventing impurities from clogging the air outlet. The airflow can maintain a dry environment inside the receiving cavity. In contrast, a humid environment caused by sweat accumulation can easily lead to moisture aging of the inner material of the silicone airbag, reducing the sealing performance and lifespan of the silicone airbag. Airflow can dissipate heat and reduce sweat accumulation, slowing down the aging rate of the silicone airbag material and extending its lifespan. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0015] Please see Figures 1-4A retractable and retractable bionic working hand device includes a bionic hand 1, a receiving cavity 2, and a connecting ring 201. The receiving cavity 2 is provided with a protective component and an auxiliary component. The protective component includes a silicone airbag 4, which is fixedly connected to the inner wall of the connecting ring 201. An air pump 3 is fixedly connected to the outer surface of the connecting ring 201, and an air outlet pipe 303 is provided inside the air pump 3. The end of the air outlet pipe 303 away from the air pump 3 is located inside the silicone airbag 4. The auxiliary components include multiple air outlets 5, and each of the multiple air outlets 5 is equipped with a pressure valve 501. An air inlet pipe 301 is fixedly connected to one side of the outer surface of the air pump 3, and a filter plate 302 is installed inside the air inlet pipe 301.
[0016] With the above technical solution, when used by a person with disabilities, the receiving cavity 2 is placed on the limb, and then the bionic hand 1 is inserted through the connecting ring 201 into the receiving cavity 2 to complete the connection. Then, the suction pump 3 on one side of the connecting ring 201 is turned on, drawing gas from the outside. The gas enters the suction pump 3 through the air inlet pipe 301. During the suction process, the outside air is filtered by the filter plate 302. The gas drawn in by the suction pump 3 is introduced into the silicone airbag 4 through the air outlet pipe 303, causing the silicone airbag 4 to inflate. The silicone airbag 4 is located inside the connecting ring 201 and the receiving cavity 2. When the silicone airbag 4 inflates, the limiting plate 402 limits the maximum expansion range of the silicone airbag 4. Through the above technical solution, the silicone airbag 4, through inflation, can tightly fit the connection gap between the receiving cavity 2 and the connecting ring 201. Compared with traditional rubber rings, its flexible material can adapt to the irregular contours of the residual limb, such as scars and muscles. The uneven surface formed by shrinkage avoids sealing dead corners due to shape mismatch, improving the protection of the bionic hand 1. The flexible padding layer formed after the silicone airbag 4 is inflated can isolate the edge of the receiving cavity 2 from direct contact with the skin of the residual limb, reducing friction and pressure between the bionic hand 1 and the skin during use, such as gripping and limb movement, reducing the risk of skin abrasion and indentation on the residual limb, and indirectly improving the comfort of long-term wear. Secondly, the filter plate 302 in the air intake pipe 301 can intercept dust, pollen, hair and other impurities in the air, preventing such pollutants from entering the silicone airbag 4 or the receiving cavity 2 with the air intake, preventing the silicone airbag 4 from being affected by the accumulation of impurities, and also preventing impurities from contacting the skin of the residual limb and causing problems such as allergies and folliculitis. In addition, the silicone airbag 4 protects the connection between the receiving cavity 2 and the bionic hand 1 from rain or dust. When the bionic hand 1 is not in use, the silicone airbag 4 can be deflated after disconnecting the receiving cavity 2 from the bionic hand 1 for storage.
[0017] Through the above technical solution, when the silicone airbag 4 expands to the maximum range of the limiting plate 402, the air pump 3 continues to intake air. At this time, the excess gas breaks through the pressure valves 501 inside the multiple air outlets 5, and is discharged through the air outlets 5. The gas is blown into the inside of the receiving cavity 2 through the air outlets 5. Through the above technical solution, after the excess gas is blown into the receiving cavity 2 through the air outlets 5, an airflow circulation can be formed between the residual limb and the inner wall of the receiving cavity 2, directly carrying away the heat generated by the metabolism of the residual limb, while accelerating the evaporation of sweat and preventing sweat from accumulating inside the receiving cavity. This not only relieves the feeling of stuffiness, but also reduces the irritation of sweat to the skin of the residual limb, and reduces problems such as eczema and dermatitis caused by sweat soaking. Sweat can cause skin problems of the residual limb. The silicone airbag 4 can adhere to the inner wall of the receiving cavity 2, potentially causing skin traction damage when wearing or removing it. Airflow circulation helps keep the inner wall of the receiving cavity dry, reducing adhesion, improving the smoothness of wearing the device, and lowering the risk of secondary skin damage. At the same time, the filter plate 302 filters impurities in the air, preventing them from contaminating the skin of the residual limb and avoiding clogging of the air outlet 5. Airflow helps maintain a dry environment inside the receiving cavity 2. In contrast, a damp environment caused by sweat accumulation can lead to moisture aging of the inner material of the silicone airbag 4, reducing its sealing performance and lifespan. Airflow cooling reduces sweat accumulation, slowing down the aging rate of the silicone airbag 4 material and extending its lifespan.
[0018] Specifically, the connecting ring 201 is fixedly connected to one side of the outer surface of the receiving cavity 2, and the silicone airbag 4 is disposed inside the receiving cavity 2.
[0019] With the above technical solution, the silicone airbag 4 is set inside the connecting ring 201 and the receiving cavity 2, and the silicone airbag 4 provides cushioning.
[0020] Specifically, a plurality of limiting posts 401 are fixedly connected to one side of the outer surface of the connecting ring 201, and a limiting plate 402 is fixedly connected to the side of the plurality of limiting posts 401 away from the connecting ring 201.
[0021] Through the above technical solution, when the silicone airbag 4 inflates, the limiting plate 402 limits the silicone airbag 4 to its maximum expansion range.
[0022] Specifically, the bionic hand 1 passes through the connecting ring 201 and is disposed inside the receiving cavity 2.
[0023] The above technical solution uses the fixed threaded rod 12 to fix the connecting plate 5 to the bottom of the UAV body 14.
[0024] Specifically, the bionic hand 1 passes through the connecting ring 201 and is disposed inside the receiving cavity 2.
[0025] With the above technical solution, when a person with disabilities uses it, the receiving cavity 2 is placed on the limb, and then the bionic hand 1 is inserted through the connecting ring 201 into the inside of the receiving cavity 2 to complete the connection.
[0026] Specifically, the silicone airbag 4 is made of medical-grade liquid silicone, and the multiple air outlets 5 are all made of medical-grade ABS plastic.
[0027] Through the above technical solutions, medical-grade liquid silicone has excellent flexibility and elasticity, and can closely conform to the irregular contours of the residual limb after inflation.
[0028] In use, when a person with disabilities uses the device, the receiving cavity 2 is placed on the limb, and then the bionic hand 1 is inserted through the connecting ring 201 into the receiving cavity 2 to complete the connection. The air pump 3 on one side of the connecting ring 201 is then turned on, drawing air from the outside through the air pump 3. The air enters the air pump 3 through the air inlet pipe 301. During the air pumping process, the outside air is filtered by the filter plate 302. The air drawn in by the air pump 3 is introduced into the silicone airbag 4 through the air outlet pipe 303, causing the silicone airbag 4 to inflate. The silicone airbag 4 is located inside the connecting ring 201 and the receiving cavity 2. When the silicone airbag 4 inflates, the limiting plate 402 limits the maximum expansion range of the silicone airbag 4. Through this technical solution, the silicone airbag 4, through inflation, can tightly fit the connection gap between the receiving cavity 2 and the connecting ring 201. Compared with traditional rubber rings, its flexible material can adapt to the irregular contours of the residual limb, such as scars and muscle atrophy. The concave and convex surfaces prevent sealing dead angles caused by shape mismatch, improving the protection of the bionic hand 1. The flexible padding layer formed after the silicone airbag 4 is inflated can isolate the edge of the receiving cavity 2 from direct contact with the skin of the residual limb, reducing friction and pressure between the bionic hand 1 and the skin during use, such as gripping and limb movement, reducing the risk of skin abrasion and indentation on the residual limb, and indirectly improving the comfort of long-term wear. Secondly, the filter plate 302 in the air intake pipe 301 can intercept dust, pollen, hair and other impurities in the air, preventing such pollutants from entering the silicone airbag 4 or the receiving cavity 2 with the air intake, preventing the silicone airbag 4 from being affected by the accumulation of impurities, and also preventing impurities from contacting the skin of the residual limb and causing allergies, folliculitis and other problems. In addition, the silicone airbag 4 protects the connection between the receiving cavity 2 and the bionic hand 1 from rain or dust. When the bionic hand 1 is not in use, the silicone airbag 4 can be deflated after disconnecting the receiving cavity 2 from the bionic hand 1 for storage. When the silicone airbag 4 inflates to the maximum range of the limiting plate 402, the air pump 3 continues to intake air. At this time, the excess gas breaks through the pressure valves 501 inside the multiple air outlets 5 and is discharged through the air outlets 5. The gas is blown into the inside of the receiving cavity 2 through the air outlets 5. Through the above technical solution, after the excess gas is blown into the receiving cavity 2 through the air outlets 5, an airflow circulation can be formed between the residual limb and the inner wall of the receiving cavity 2, directly carrying away the heat generated by the metabolism of the residual limb, while accelerating the evaporation of sweat and preventing sweat from accumulating inside the receiving cavity. This not only relieves the feeling of stuffiness, but also reduces the irritation of sweat to the skin of the residual limb, reducing problems such as eczema and dermatitis caused by sweat soaking. Sweat can cause the skin of the residual limb to irritate the skin of the receiving cavity 2. The inner wall of the receiving cavity 2 may become sticky, potentially causing skin traction damage when wearing or removing the device. Airflow circulation can keep the inner wall of the receiving cavity dry, reducing stickiness, improving the smoothness of device wear, and reducing the risk of secondary skin damage. At the same time, the filter plate 302 filters impurities in the air, preventing impurities from contaminating the skin of the residual limb and avoiding impurities from clogging the air outlet 5. Airflow can maintain a dry environment inside the receiving cavity 2. In contrast, a humid environment with accumulated sweat can easily cause the inner material of the silicone airbag 4 to become damp and age, reducing the sealing performance and service life of the silicone airbag 4. Airflow can dissipate heat and reduce sweat accumulation, slowing down the aging rate of the silicone airbag 4 material and extending its service life.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
