Description

Technical Field

[0001] This utility model belongs to the field of bionic mechanical technology, specifically, it relates to a torque generator and a prosthesis. Background Technology

[0002] A prosthesis, also known as a prosthetic limb, is an artificial limb used by amputees to compensate for the function of the missing limb. There are upper limb prostheses and lower limb prostheses. They are mostly made of materials such as aluminum plates, wood, leather, and plastic, with metal components used for the joints. Currently, titanium alloys and carbon fiber materials are the mainstream materials in the prosthesis industry. A prosthesis refers to an artificial limb used to replace a limb with functional impairment or to conceal a limb injury.

[0003] Lower limb prostheses use a torque converter to attach between the components above the foot and below the knee, typically within the leg tube. When wearing a lower limb prosthesis, a person may encounter issues with small-amplitude torso rotation, such as turning their head. The lower leg ankle joint actually needs to rotate, but because most lower limb prostheses are currently rigidly connected with metal leg tubes, only the knee joint can bend, or some ankle joints can rotate forward, backward, or sideways. When a person wants to perform small-amplitude torso rotations, the prosthetic foot must leave the ground, thus limiting the body's movement to some extent. Utility Model Content

[0004] The purpose of this utility model is to provide a torque generator and a prosthesis, which aims to solve the technical problem in the prior art that when a person wants to make a small-amplitude body rotation, the foot of the prosthesis must leave the ground, which restricts the movement of the human body to a certain extent.

[0011] When the torque device is subjected to force and the magnitude of the force is greater than the buffer threshold of the second buffer component, the second buffer component and the first buffer component are subjected to force in sequence and generate a buffering effect.

[0012] Preferably, the second buffer component is a hydraulic structure with one end connected to the upper body and the other end connected to the connecting member; when the hydraulic structure is subjected to torque, it causes the upper body to rotate relative to the connecting member.

[0017] Preferably, the connector is a plate structure, and the upper end face of the connector is provided with a receiving groove adapted to the first buffer component; the connector is provided with mounting holes adapted to the second buffer component.

[0018] Preferably, the connecting body is a rectangular plate, and a receiving groove is provided at each of the four corners of the rectangular plate; the first buffer component corresponds to each of the receiving grooves.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0034] The following description, in conjunction with the accompanying drawings, details a torque generator and prosthesis provided in this application through specific embodiments and application scenarios.

[0035] Please refer to the following: Figures 1 to 6 This invention provides a torque converter. The torque converter includes: a lower body 1, a first buffer assembly 2, a connecting body 3, a second buffer assembly 4, and an upper body 5. The first buffer assembly 2 is connected to the connecting body 3; the second buffer assembly 4 is connected to the end of the connecting body 3 opposite to the first buffer assembly 2; the lower body 1 is connected to the first buffer assembly 2 and is used to connect to any external component; the upper body 5 is connected to the second buffer assembly 4 and is used to connect to another external component. When the torque converter is subjected to force greater than the buffering threshold of the second buffer assembly 4, the second buffer assembly 4 and the first buffer assembly 2 are subjected to force sequentially and generate a buffering effect. Specifically, the magnitude of the force on the torque converter is preset as 'a'. The threshold value for the buffering effect of the second buffer assembly 4 is 'b'. The threshold value for the buffering effect of the first buffer assembly is 'c'. Wherein, 'b' is less than 'a'. The force 'a' received by the torque generator first acts on the second buffer component 4, which provides buffering. The maximum buffering force is 'b'. Excess force is then transmitted to the first buffer component 2 through the connecting body 3. The first buffer component 2 receives force and generates a buffering effect. When the torque generator receives force and the magnitude of the force is not greater than the buffering threshold of the second buffer component 4, the second buffer component 4 receives force and generates a buffering effect. The buffering effect of the first buffer component 2 is not activated.

[0036] This utility model provides a torque converter that, compared with the prior art, achieves multiple buffering effects when subjected to force through the arrangement of the first buffer component 2 and the second buffer component 4. This effectively solves the problem that when a person wants to make a small-amplitude torso rotation, the prosthetic foot must leave the ground, thus restricting the person's movement to a certain extent. This significantly improves the user experience of the torque converter.

[0037] As one specific implementation of this utility model, please refer to the following: Figures 1 to 6The second buffer component 4 is a hydraulic structure that is connected to the upper body 5 at one end and to the connecting member 3 at the other end. When the hydraulic structure is subjected to torque, it causes the upper body 5 to tend to rotate relative to the connecting member 3 or causes the upper body 5 to rotate relative to the connecting member 3.

[0038] As one specific implementation of this utility model, please refer to the following: Figures 1 to 6 The first buffer assembly 2 includes: a pull post 21 and a carbon fiber tube 22. One end of the pull post 21 is connected to the connecting body 3 and the other end is connected to the lower body 1. The carbon fiber tube 22 is sleeved outside the pull post 21. One end of the carbon fiber tube 22 is connected to the connecting body 3 and the other end is connected to the lower body 1.

[0039] In some feasible embodiments, the pull post 21 is detachably connected to the lower body 1. In any feasible embodiment, the pull post 21 is connected to the lower body 1 by a screw 23. The screw 23 facilitates the disassembly of the first buffer assembly 2.

[0040] In some feasible embodiments, the number of first buffer components 2 is multiple, which can effectively improve the buffering effect of the first buffer components 2.
