Description

Technical Field

[0001] The utility model relates to the technical field of mechanical bionic exoskeleton manufacturing, in particular to a sitting posture load-bearing 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 existing patent application with application number CN202110070209.5 and titled "A spinal structure and mechanical exoskeleton suitable for mechanical exoskeleton" discloses a mechanical exoskeleton structure, which mainly includes a spinal structure and a leg exoskeleton. The existing mechanical exoskeleton structure can transmit force to the ground through force conduction, and also reduce the burden on the human body. However, when the legs are bent and squatted into a sitting position, the thigh and the spinal structure are at a nearly 90° angle, which makes force transmission difficult and lacks support for the buttocks. Therefore, its structure needs to be further improved. Utility Model Content

[0004] The purpose of the utility model is to make up for the above-mentioned deficiencies and to disclose to the public a mechanical bionic exoskeleton sitting load-bearing structure which has a simple and reasonable structure, is easy to manufacture, and can reduce the stress on the legs, waist and back of the user when squatting.

[0005] The technical solution of the utility model is achieved in this way:

[0006] A sitting load-bearing structure of a mechanical bionic exoskeleton comprises a bionic waist and hips and a bionic leg. A sitting load-bearing belt is arranged between the upper part of the bionic thigh of the bionic leg.

[0007] The measures to further optimize this technical solution are:

[0008] As an improvement, a waist fixing belt is fixed on the bionic waist and hips.

[0009] As an improvement, a connecting portion is provided between the sitting weight-bearing belt and the waist fixing belt.

[0010] As an improvement, the connecting portion is in a belt-like structure, and a plurality of connecting portions are arranged at intervals between the sitting weight-bearing belt and the waist fixing belt.

[0011] The sitting weight-bearing belt and the waist fixing belt are connected through a connecting part, so that force can be transmitted between the sitting weight-bearing belt and the waist fixing belt, which is beneficial to the transmission of force of the entire mechanical exoskeleton.

[0012] As an improvement, the sitting posture load-bearing belt and the waist fixing belt are in an integral structure, which has better integrity and is conducive to the transmission of force.

[0013] As an improvement, a connection hole for connecting a sitting weight-bearing belt is provided on the inner side of the upper part of the bionic thigh.

[0014] As an improvement, a load-bearing part is provided in the middle of the sitting load-bearing belt, and connecting belts are provided at both ends of the load-bearing part, and the width of the load-bearing part is greater than the width of the connecting belt. Such an arrangement can improve the comfort during use.

[0015] As an improvement, the outer end of the connecting belt is connected with a hook. The hook is provided to facilitate the disassembly and assembly of the sitting weight-bearing belt.

[0016] As an improvement, the load-bearing part is provided with a buffer layer.

[0017] As an improvement, the buffer layer is composed of buffer blocks distributed in a matrix.

[0018] The setting of the cushion layer can further enhance the comfort during use.

[0019] The advantages of the utility model compared with the prior art are:

[0020] The utility model provides a mechanical bionic exoskeleton sitting load-bearing structure, which has a simple and reasonable structure. A sitting load-bearing belt is arranged between the upper part of the bionic thigh of the bionic leg. When the user wears the exoskeleton and squats to a sitting position, the sitting load-bearing belt is supported near the thigh root of the user to provide the user with a supporting force. As a reaction force, the weight of the human body is transmitted to the ground along the bionic leg through the sitting load-bearing belt, which can greatly reduce the burden on the bones and muscles of the user when squatting to a sitting position. In addition, the setting of the sitting load-bearing belt makes the bionic leg part have better integrity, which can improve the action followability of the mechanical exoskeleton.

Therefore, the above terms should not be understood as limitations on the present invention.

[0032] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0033] Embodiment 1, as Figures 1 to 4As shown, a sitting load-bearing structure of a mechanical bionic exoskeleton includes a bionic waist and hip 1 and a bionic leg 2, and a sitting load-bearing belt 3 is arranged between the upper part of the bionic thigh 21 of the bionic leg 2.

[0034] The upper inner side of the bionic thigh 21 is provided with a connection hole 21 a for connecting the sitting weight-bearing belt 3 .

[0035] The middle part of the sitting posture load-bearing belt 3 is provided with a load-bearing part 31, and both ends of the load-bearing part 31 are provided with connecting belts 32, and the width of the load-bearing part 31 is greater than the width of the connecting belt 32. Increasing the width of the load-bearing part 31 can reduce the pressure when subjected to force and improve the comfort of the user.

[0036] The outer end of the connecting belt 32 is connected with a hook 33. The hook 33 cooperates with the connecting hole 21a to facilitate the disassembly and assembly of the sitting posture load-bearing belt 3.

[0037] The load-bearing portion 31 is provided with a cushion layer 31a. The cushion layer 31a can be made of a material with a certain elasticity such as sponge or silica gel.

[0038] The buffer layer 31a is composed of buffer blocks 31b distributed in a matrix.

[0039] The cushioning layer 31a can also improve the comfort of the user, and the cushioning layer 31a is composed of cushioning blocks 31b distributed in a matrix, which facilitates the bending and deformation of the load-bearing part 31 and enables the load-bearing part 31 to better fit the user's body.

[0040] The sitting load-bearing structure of the utility model is provided with a sitting load-bearing belt 3 between the upper part of the bionic thigh 21 of the bionic leg 2. That is to say, after the user wears the mechanical exoskeleton, when the user squats into a sitting position (usually when squatting to carry heavy objects), the user's thigh root will sit on the sitting load-bearing belt 3, and the two ends of the sitting load-bearing belt 3 are respectively connected to the bionic thigh 21 of the bionic leg 2, so that the weight of the human body and the object can be transmitted to the ground through the sitting load-bearing belt 3 through the bionic leg 2, thereby reducing the burden of the user with the help of the mechanical exoskeleton and achieving the purpose of labor saving. In addition, the setting of the sitting load-bearing belt 3 makes the bionic leg 2 part have better integrity, which can improve the movement followability of the mechanical exoskeleton.

[0041] Embodiment 2, as Figure 5 As shown, the sitting load-bearing structure of this embodiment is based on the first embodiment, and a waist fixing belt 4 is fixed on the bionic waist and hips 1.

[0042] A connecting portion 5 is provided between the sitting posture load-bearing belt 3 and the waist fixing belt 4 .

[0043] The connecting portion 5 is a belt-shaped structure, and a plurality of connecting portions 5 are arranged at intervals between the sitting weight-bearing belt 3 and the waist fixing belt 4. The number of the connecting portions 5 of the belt-shaped structure is also set according to actual needs.

[0044] When the user wears the mechanical exoskeleton, the waist is fixed with the waist fixing belt 4, so that the bionic waist and hips 1 fit the user's back. The connection part 5 is used to establish a connection between the sitting weight-bearing belt 3 and the waist fixing belt 4. With this design, the weight of the human body and objects can not only be transmitted to the ground through the sitting weight-bearing belt 3 via the bionic legs 2, but also part of the weight can be transmitted to the bionic waist and hips 1 through the connection part 5 via the waist fixing belt 4, and then transmitted to the ground through the bionic legs 2, thus forming a composite transmission of force, making the whole mechanical exoskeleton more labor-saving.

[0045] Embodiment three, as Figure 6 As shown, the sitting load-bearing structure in this embodiment is similar to that in the second embodiment, except that in this embodiment, the sitting load-bearing belt 3 and the waist fixing belt 4 are an integral structure. This arrangement makes the sitting load-bearing belt 3 and the waist fixing belt 4 have better integrity, which is conducive to the transmission of force.

[0046] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments. Without departing from the principles, the embodiments of the present invention may be deformed or modified in any way.
