Description

Technical Field

[0001] The utility model relates to the technical field of mechanical bionic exoskeleton manufacturing, in particular to a sole structure of a mechanical bionic exoskeleton. Background Art

[0002] With the development of science and technology, the degree of mechanization in many industries is constantly improving. With the help of machinery, many physical labors that were originally done by workers can be completed. However, in some occasions, manpower is still needed to complete the handling work. When workers complete lifting, unloading, moving and other handling actions, they need to perform repetitive actions continuously. After working for a long time, the arms, legs, waist and back and various joints are prone to fatigue. If this continues for a long time, these parts are prone to overwork and illness. Mechanical bionic exoskeleton is a wearable exoskeleton that shares part of the external force through the exoskeleton, and transmits the force directly to the ground through a continuous exoskeleton, thereby achieving the purpose of reducing the stress on the human skeleton.

[0003] The wearable exoskeleton may include shoulders, back, waist, legs and soles from top to bottom. Since the size of the user's feet is different, when wearing the sole, there may be a situation where the sole is not suitable, such as the sole is too small or too large. As disclosed in the patent application with application number CN202021148990.0 and the name "A wearable sitting and squatting assist device for automobile assembly workers", the toe cap is not replaceable. As described in the application specification, the toe cap adopts the corresponding shoe size of 45 or above. In order to ensure that most people can wear it, the toe cap size is designed to be larger, but for ordinary people, this shoe size is obviously too large, that is, when wearing it, it will shake due to the large gap, and there will be problems of not fitting or unreliable fixation.

[0004] In order to overcome the above problems, a sole structure that is easy to replace has been designed (application number CN202320216388.3 and name “A replaceable sole for a mechanical bionic exoskeleton”). The connecting parts of this design are detachable and matched with the sole body, and can adapt to feet of different sizes by replacing soles of different sizes. However, shoes of the same size will have certain differences in size due to different styles, resulting in the sole being unable to fully match the user's shoes, so its structure needs further improvement. Utility Model Content

[0005] The purpose of the utility model is to make up for the above-mentioned deficiencies and disclose to the public a mechanical bionic exoskeleton sole structure which has a simple and reasonable structure, can adapt to the size of shoes in a small range, and fits the shoes more closely when worn.

[0006] The technical solution of the utility model is achieved in this way:

[0007] A sole structure of a mechanical bionic exoskeleton includes a sole body, the sole body includes a bottom surface in an integrated structure, the front end of the bottom surface is provided with an elastic positioning part that covers the toe from front to back, the elastic positioning part is provided with a positioning hole corresponding to the big toe part, and the rear end of the bottom surface is provided with an elastic limiting part that wraps the heel from back to front.

[0008] The measures to further optimize this technical solution are:

[0009] As an improvement, an inner part is embedded in the rear of the bottom surface, and a plurality of through holes are arranged on the inner part. The arrangement of the inner part can increase the strength of the sole, and the inner part is only arranged at the rear of the bottom surface, which can ensure that the bending of the sole is not affected when the rear end of the bottom surface is subjected to force and does not deform.

[0010] As an improvement, a connecting piece for connecting the bionic calf is fixed on the bottom surface, and the connecting piece and the embedded piece are in an integrated structure. Such a design is convenient for processing.

[0011] As an improvement, the inner insert is laterally provided with reinforcing ribs, which can further increase the strength of the sole.

[0012] As an improvement, the two sides of the elastic limiting part are respectively provided with edging, and the middle part of the elastic limiting part is provided with a cavity. The provision of the cavity can play a certain positioning role, and can also increase the deformation amount of the elastic limiting part to a certain extent.

[0013] As an improvement, the upper end of the elastic limiting portion is formed with a guide portion extending backward and upward. When the user wears the sole, the heel can directly step into the sole along the guide portion.

[0014] As an improvement, the front side of the hemming extends forward and upward to form an extension portion, and the end of the extension portion is provided with a connection hole for connecting a strap.

[0015] As an improvement, the bottom surface is provided with weight-reducing holes, which can reduce the weight of the sole, thereby reducing the burden on the user when lifting his foot.

[0016] As an improvement, both sides of the middle of the bottom surface are respectively provided with belt holes for connecting the fixing belt.

[0017] As an improvement, the middle part of the elastic positioning part extends backward to form a rear extension part. The arrangement of the rear extension part can increase the coverage of the elastic positioning part on the toe and improve the reliability of the connection between the sole and the user's shoe.

[0018] The advantages of the utility model compared with the prior art are:

[0019] The utility model discloses a mechanical bionic exoskeleton sole structure, which has a simple and reasonable structure and comprises a bottom surface of an integrated structure, and an elastic positioning part covering the toe from front to back is arranged at the front end of the bottom surface, and an elastic limiting part covering the heel from back to front is arranged at the rear part. The sole structure fixes the user's shoes by using the elastic deformation of the material itself, and can better fit the shoes. The elasticity of the material is used to make the sole have a certain degree of adaptability, and can adapt to shoes of different versions, and can even be suitable for shoes of front and back sizes. For example, a sole of size 41 can adapt to shoes of size 40-42, and has stronger adaptability. The arrangement of the positioning holes on the elastic positioning part can increase the deformation amount of the elastic positioning part, so that it has better covering property for the toe, and at the same time, the toe can be better positioned to prevent the shoe from slipping.

[0031] like Figures 1 to 5 As shown, a sole structure of a mechanical bionic exoskeleton includes a sole body, wherein the sole body includes a bottom surface 1 in an integrated structure, a front end of the bottom surface 1 is provided with an elastic positioning portion 2 that covers the toe from front to back, a positioning hole 2a is provided on the elastic positioning portion 2 corresponding to the big toe portion, and a rear end of the bottom surface 1 is provided with an elastic limiting portion 3 that wraps the heel from back to front.

[0032] The rear part of the bottom surface 1 is embedded with an inner part 4, and a plurality of through holes 4a are provided on the inner part 4. The provision of the inner part 4 can improve the strength of the sole, and the inner part 4 is provided at the rear part of the bottom surface 1 (can extend forward to the middle and rear part of the bottom surface), which can ensure that the bending of the sole is not affected when the rear end of the bottom surface 1 is subjected to force and does not deform.

[0033] A connecting piece 5 for connecting the bionic calf is fixed on the bottom surface 1 , and the connecting piece 5 and the embedded piece 4 are in an integrated structure.

[0034] The inner insert 4 is laterally provided with reinforcing ribs 41. In this embodiment, the cross section of the reinforcing ribs 41 is a "convex"-shaped structure.

[0035] In this embodiment, the sole adopts the insert injection molding process. After the inner insert 4 is processed, it is placed in the mold for injection molding. After the injection molding, the injection molding material covers the inner insert 4, and the injection molding material and the inner insert 4 are firmly combined to form a fixed structure. Since the connecting member 5 and the inner insert 4 are an integral structure, the connection between the connecting member 5 and the sole is also achieved during the injection molding. A through hole 4a is set on the inner insert 4. During the injection molding process, the injection molding material enters the through hole 4a, so that the injection molding materials above and below the inner insert 4 can be connected into a whole.

[0036] Edges 31 are provided on both sides of the elastic limiting portion 3 , and a cavity 3a is provided in the middle of the elastic limiting portion 3 .

[0037] The upper end of the elastic limiting portion 3 is formed with a guide portion 32 extending backward and upward.

[0038] The front side of the hem 31 extends forward and upward to form an extension portion 33, and a connection hole 33a for connecting a strap is provided at the end of the extension portion 33. The strap can be connected through the connection hole 33a, and after the sole is worn, it can be fixed with the strap, which can further improve the reliability of wearing the sole.

[0039] The injection-molded elastic limiting part 3 has a certain hardness and elasticity. The elastic limiting part 3 is in an upright state. When wearing the sole, the user inserts the toe into the elastic positioning part 2 of the head, and the heel is stepped down along the guide part 32, which is convenient to wear. When the toe is inserted, the big toe of the toe is inserted into the positioning hole 2a of the elastic positioning part 2, and the positioning effect of the positioning hole 2a is used to prevent the shoe from slipping; in addition, the positioning hole 2a is provided to increase the deformation of the elastic positioning part 2, so that it has better coverage for the toe. Similarly, the setting of the cavity 3a on the elastic limiting part 3 can increase the deformation of the elastic limiting part 3 while having a certain limiting effect, so that the sole has better adaptability.

[0040] The bottom surface 1 is provided with weight-reducing holes 1a. The mechanical bionic exoskeleton is worn as a whole on the user during use, and the setting of the weight-reducing holes 1a can reduce the weight of the sole, thus reducing the burden on the user when lifting his feet.

[0041] The middle part of the bottom surface 1 is provided with holes 1b for connecting the fixing belt. Similarly, the fixing belt can be connected to the middle part of the bottom surface 1 by using the holes 1b, and the fixing belt can be used to fix the shoe after wearing it, which can further improve the reliability of wearing the shoe.

[0042] The middle part of the elastic positioning part 2 extends backward to form a rear extension part 21. The arrangement of the rear extension part 21 can improve the covering property of the elastic positioning part 2 on the toe and improve the reliability of wearing the sole.

[0043] The utility model discloses a mechanical bionic exoskeleton sole structure, which has a simple structure and an integrated bottom surface. An elastic positioning portion 2 covering the toe from front to back is arranged at the front end of the bottom surface 1, and an elastic limiting portion 3 covering the heel from back to front is arranged at the rear. The sole structure fixes the user's shoes by utilizing the elastic deformation of the material itself, and can better fit the shoes. The elasticity of the material is utilized to make the sole have a certain degree of adaptability, and can adapt to shoes of different versions, and can even be applicable to shoes of different sizes. For example, a size 41 sole can adapt to shoes of sizes 40-42, and has stronger adaptability.
