Description

Technical Field

[0001] The utility model relates to the technical field of bionic manipulators, in particular to a bionic manipulator with a limiting structure. Background Art

[0002] Robot is a high-tech product with broad application prospects. The bionic hand was first developed to help children harmed by the sedative hypnotic thalidomide. As part of a research project, it looks and moves like a real hand. Later, the world's first "bionic hand" factory, Touch Bionics, was officially established in Scotland, UK, and began to tailor this prosthetic hand for customers. Today, the improved bionic hand uses the most cutting-edge electronic and mechanical technology and is made of high-strength plastic. This lightweight hand has become the world's first new generation of prosthetic products. In terms of robot fingers, there are already many types of fingers with different structures. The core technology is the independently developed machine sensor that transmits human brain signals to the machine bionic hand, so that the robot hand can imitate the flexibility of human hands.

[0003] The existing bionic manipulators for the disabled are heavy and inconvenient for daily use. The most important part of the weight is concentrated on the chassis, and thicker alloy materials are needed to connect the hand frame and the chassis. Therefore, a lightweight bionic manipulator is needed to solve the above problems. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a lightweight bionic manipulator, wherein a base rear support cylinder is provided below the hand frame, an arm tube seat is connected below the base rear support cylinder, and the arm tube seat is connected to the hand frame through a frame base.

[0005] A further improvement of the utility model is that a fixed installation hole structure is provided in the middle position of the skeleton base, and auxiliary installation hole groups are provided on both sides of the fixed installation hole structure.

[0006] A further improvement of the utility model is that the auxiliary installation control group includes two auxiliary installation holes, one of which has a diameter that is half of the other. Such a hole size setting is for easier installation and can also increase the stability of the overall installation.

[0007] A further improvement of the utility model is that a layer of anti-skid pad structure is provided on the inner sides of the auxiliary mounting hole and the fixed mounting hole structure, which can play the role of firm connection and anti-slip, thereby improving the stability after installation and use by the user.

[0008] A further improvement of the utility model is that the skeleton base is installed vertically above the arm tube seat through a connecting surface, and the setting of the vertical angle can play a role in stabilizing the overall structure.

[0009] A further improvement of the utility model is that the end surface of the connecting surface is an arc-shaped surface structure. Setting the end surface as an arc-shaped surface structure can protect the base and can also imitate the arc surface of a human arm to improve the comfort of the user.

[0010] A further improvement of the utility model is that a hollow structure is formed between the hand frame and the arm tube seat, and this hollow structure can greatly reduce the weight of the bionic hand.

[0011] Beneficial effects of the utility model:

[0012] The design of the utility model can reduce the weight of the existing bionic manipulator for the disabled, making it easier to use in daily life. The heavy chassis can be reasonably structurally arranged to reduce the weight of the chassis structure, thereby improving the comfort of the user. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0019] The utility model relates to a lightweight bionic manipulator, wherein a base rear support cylinder 2 is provided below the hand frame 1, an arm tube seat 3 is connected below the base rear support cylinder 2, and the arm tube seat 3 is connected to the hand frame 1 through a frame base 4; a fixed mounting hole structure 5 is provided in the middle position of the frame base 4, and auxiliary mounting hole groups 6 are provided on both sides of the fixed mounting hole structure 5; the auxiliary mounting control group 6 includes two auxiliary mounting holes 7, wherein the diameter of one auxiliary mounting hole 7 is half the diameter of the other auxiliary mounting hole 7, and such aperture size setting is for facilitating installation and also for increasing the stability of the whole after installation.

[0020] The inner sides of the auxiliary mounting hole 7 and the fixed mounting hole structure 5 are both provided with a non-slip cushion structure 8, which can ensure a firm connection and prevent sliding, thereby improving the stability after installation and use by the user; the skeleton base 4 is vertically installed on the top of the arm tube seat 10 through the connecting surface 9, and the vertical angle setting can stabilize the overall structure; the lower end face of the connecting surface 9 is an arc-shaped surface structure 11, and setting the end face as the arc-shaped surface structure 11 can protect the base, and can also imitate the arc surface of the human arm to improve the comfort of the user; there is a hollow structure 12 between the hand skeleton 1 and the arm tube seat 10, and this section is set as the hollow structure 12 to greatly reduce the weight of the bionic hand.

[0021] It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which are all within the protection scope of the utility model.
