[0001] This utility model relates to the field of embodied mechanical technology, specifically an auxiliary mechanical leg based on embodied intelligent walking. Background Technology

[0002] Embossed machines refer to intelligent agents that possess a body and are capable of interacting with the physical world, representing one of the cutting-edge development directions of artificial intelligence technology. Embossed mechanical legs can enable users or other machines to better control and use them, but existing embossed mechanical legs have some shortcomings, such as:

[0003] Application No.: CN202221198418.4 describes an intelligent walking mechanical leg. When in use, the strain sensor converts the force into an electrical signal to control the rotation of the servo motor on the same side, which in turn drives the thigh and calf legs to rotate together, thereby assisting the user in walking or climbing stairs. However, in actual use, it is difficult to adjust the length of the device, which may lead to different people having difficulty adapting to it.

[0004] Therefore, we propose an assistive mechanical leg based on embodied intelligent walking to address the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary mechanical leg based on embodied intelligent walking, in order to solve the problem mentioned in the background art that most embodied intelligent mechanical legs on the market are difficult to adjust in length, which may lead to different people having difficulty adapting when using them.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary mechanical leg based on embodied intelligent walking, including a mechanical leg body and an installation sleeve disposed on the top of the mechanical leg body. The mechanical leg body is provided with a controller and an extension mechanism. The bottom of the extension mechanism is connected to a bottom leg, and the bottom of the bottom leg is connected to a twisting mechanism. The bottom of the twisting mechanism is connected to a mechanical foot.

[0007] The controller is electrically connected to the extension mechanism and the torsion mechanism. The extension mechanism can drive the bottom leg to rise and fall, and the extension mechanism can drive the torsion mechanism to run. When the torsion mechanism is running, the mechanical foot will rotate at an angle.

[0008] The extension mechanism makes it easier for users to adjust the distance between the mechanical leg body and the base leg, allowing them to better adapt to different lengths. The twisting mechanism also makes it easier for the base leg to rotate the mechanical foot, thus increasing the adjustability of the device during operation.

[0009] As a preferred technical solution of this utility model, the installation sleeve is provided with a sensing pad inside, and the sensing pad is electrically connected to the controller, and the sensing pad can sense the movement of the leg connection part.

[0010] The above technical solution enables the installation sleeve to be connected more stably, allowing other devices to connect with the mechanical leg body.

[0011] As a preferred technical solution of this utility model, the mechanical leg body is fixedly connected to the mounting sleeve, and the extension mechanism includes a drive motor, and a first sprocket is connected to the bottom of the drive motor. A chain is engaged on the outer side of the first sprocket, and a second sprocket is engaged on the left end of the chain. A threaded shaft is connected to the bottom of the first sprocket and the second sprocket. A threaded sleeve is provided on the outer side of the threaded shaft, and a buffer block is provided at the bottom of the threaded sleeve. The bottom of the buffer block is connected to the inside of the leg.

[0012] The above technical solution enables the drive motor to rotate the threaded shaft, which in turn causes the threaded sleeve to lift the base leg, thereby allowing for better adjustment of the equipment's height.

[0013] As a preferred technical solution of this utility model, the top of the bottom leg is provided with a telescopic fabric, and the bottom leg is connected to the bottom of the mechanical leg body through the telescopic fabric.

[0014] The above technical solution allows the distance between the mechanical leg body and the base leg to be covered by a telescopic fabric, thereby increasing the protection of the device during use.

[0015] As a preferred technical solution of this utility model, a fixed foot is connected to the bottom of the leg, and a rotating ring is connected to the bottom of the fixed foot. The torsion mechanism includes a rotating shaft, which is rotatably connected to the rotating ring on the outside. The rotating shaft has a built-in servo motor, and a fixed ring is fixedly connected to the outside of the rotating shaft. The bottom of the fixed ring is fixedly connected to the mechanical foot.

[0016] The above technical solution enables the bottom leg to be more stable when connected to the torsion mechanism, and makes it easier for the rotating shaft to adjust the angle of the mechanical foot, thereby increasing the adjustability of the device.

[0017] As a preferred technical solution of this utility model, the top of the mechanical foot is provided with a first support damper and a second support damper, and the tops of the first support damper and the second support damper are fixedly connected to the fixed foot, and the bottom of the mechanical foot is provided with a foot pad.

[0018] The above technical solution enables the mechanical foot to connect more stably with the fixed foot, thereby increasing the stability of the device during use.

[0019] As a preferred technical solution of this utility model, the foot pad is a pressure sensing mechanism, and the controller is electrically connected to the drive motor, servo motor and foot pad through a circuit.

[0020] The above technical solution makes it more convenient for the controller to control devices such as drive motors and servo motors, thereby increasing the operability of the device during use.

[0021] Compared with the prior art, the beneficial effects of this utility model are: by setting the extension mechanism, it is more convenient for users to adjust the distance between the mechanical leg body and the bottom leg, and it is also more convenient for users to adapt to different lengths. Furthermore, by setting the twisting mechanism, it is more convenient for the bottom leg to drive the mechanical foot to rotate, thereby increasing the adjustability of the device during operation.

[0022] Furthermore, by using a telescopic fabric, the distance between the mechanical leg body and the base leg can be covered by the telescopic fabric, thereby increasing the protection of the device during use.

[0023] Furthermore, by setting the first and second support damping, the mechanical foot can be more stable when connected to the fixed foot, thereby increasing the stability of the device during use. Attached Figure Description

[0031] 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.

[0032] To address the difficulty in adjusting the length of mechanical legs in existing technologies, the following solution is disclosed. Please refer to [link / reference]. Figures 1-6 This utility model provides a technical solution: an auxiliary mechanical leg based on embodied intelligent walking, including a mechanical leg body 1 and an installation sleeve 2 set on the top of the mechanical leg body 1. The mechanical leg body 1 is provided with a controller 4 and an extension mechanism. The bottom of the extension mechanism is connected to a bottom leg 12. The bottom of the bottom leg 12 is connected to a twisting mechanism, and the bottom of the twisting mechanism is connected to a mechanical foot 18.

[0033] The controller 4 is electrically connected to the extension mechanism and the torsion mechanism. The extension mechanism can drive the bottom leg 12 to rise and fall, and the extension mechanism can drive the torsion mechanism to run. When the torsion mechanism is running, the mechanical foot 18 will rotate at an angle.

[0034] The mounting sleeve 2 has a sensor pad 3 inside, and the sensor pad 3 is electrically connected to the controller 4. The sensor pad 3 can sense the movement of the leg connection part. The mechanical leg body 1 is fixedly connected to the mounting sleeve 2, and the extension mechanism includes a drive motor 5. The bottom of the drive motor 5 is connected to a first sprocket 6. A chain 7 is engaged on the outside of the first sprocket 6, and a second sprocket 8 is engaged on the left end of the chain 7. A threaded shaft 9 is connected to the bottom of the first sprocket 6 and the second sprocket 8. A threaded sleeve 10 is provided on the outside of the threaded shaft 9, and a buffer block 11 is provided at the bottom of the threaded sleeve 10. The bottom of the buffer block 11 is connected to the inside of the bottom leg 12.

[0035] When the extension mechanism is running, the drive motor 5 will drive the first sprocket 6 to rotate, which in turn drives the second sprocket 8 to rotate via the chain 7. This allows the first sprocket 6 and the second sprocket 8 to simultaneously drive the threaded shaft 9 to rotate, which in turn causes the threaded shaft 9 to slide the threaded sleeve 10, which in turn causes the threaded sleeve 10 to lift and lower the bottom leg 12.

[0036] The bottom leg 12 is provided with a telescopic fabric 22 at the top, and the bottom leg 12 is connected to the bottom of the mechanical leg body 1 through the telescopic fabric 22; the bottom of the bottom leg 12 is connected to a fixed foot 13, and the bottom of the fixed foot 13 is connected to a rotating ring 14; the torsion mechanism includes a rotating shaft 15, the outer side of the rotating shaft 15 is rotatably connected to the rotating ring 14, and the rotating shaft 15 has a built-in servo motor 16; a fixed ring 17 is fixedly connected to the outer side of the rotating shaft 15, and the bottom of the fixed ring 17 is fixedly connected to the mechanical foot 18.

[0037] When the torsion mechanism is running, the servo motor 16 will drive the rotating shaft 15 to rotate, thereby causing the rotating shaft 15 to drive the fixed ring 17 and the mechanical foot 18 to rotate around the rotating shaft 15. At the same time, the first support damper 19 and the second support damper 20 will contract or extend, thereby supporting the front or rear end of the mechanical foot 18.

[0038] The top of the mechanical foot 18 is provided with a first support damper 19 and a second support damper 20, and the tops of the first support damper 19 and the second support damper 20 are fixedly connected to the fixed foot 13. The bottom of the mechanical foot 18 is provided with a foot pad 21. The foot pad 21 is a pressure sensing mechanism, and the controller 4 is electrically connected to the drive motor 5, the servo motor 16 and the foot pad 21 through a circuit.

[0039] Working principle: When using the assisted mechanical leg based on embodied intelligent walking, first connect the device power supply and the power grid to supply power, and then make the controller 4 drive the extension mechanism to operate, thereby adjusting the distance between the bottom leg 12 and the mechanical leg body 1, which can extend the mechanical leg body 1. When the mechanical leg body 1 is walking, the controller 4 can start the twisting mechanism to operate, thereby making the twisting mechanism drive the mechanical foot 18 to adjust the angle, thereby simulating the steps of the foot when a person walks;

[0040] When the extension mechanism is running, the drive motor 5 will drive the first sprocket 6 to rotate, which in turn drives the second sprocket 8 to rotate via the chain 7. This allows the first sprocket 6 and the second sprocket 8 to simultaneously drive the threaded shaft 9 to rotate, which in turn causes the threaded shaft 9 to slide the threaded sleeve 10, which in turn causes the threaded sleeve 10 to lift and lower the bottom leg 12.

[0041] When the torsion mechanism is running, the servo motor 16 will drive the rotating shaft 15 to rotate, thereby causing the rotating shaft 15 to drive the fixed ring 17 and the mechanical foot 18 to rotate around the rotating shaft 15. At the same time, the first support damper 19 and the second support damper 20 will contract or extend, thereby supporting the front or rear end of the mechanical foot 18.

[0042] This completes a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
