Description

Technical Field

[0001] This utility model relates to the field of multi-legged robot technology, specifically to a multi-legged robot. Background Technology

[0002] A robot is an automated machine, but unlike humans or other living beings, it possesses intelligent capabilities similar to humans, such as perception, planning, movement, and coordination. It is a highly flexible automated machine. Robots can assist or even replace humans in performing dangerous, arduous, and complex tasks, improving work efficiency and quality, serving human life, and expanding the scope of human activities and capabilities. Hexapod walking robots, also known as spider robots, utilize biomimetic principles, drawing inspiration from the triangular gait of six-legged insects. They possess excellent balance, move freely forward and backward, are simple to control, move quickly and smoothly, and have the ability to overcome obstacles, adapting to various complex terrains.

[0003] After prolonged use, the foot pads on the bottom of the legs of a multi-legged robot will wear down and need to be replaced. Currently, replacing the foot pads requires removing multiple tiny screws with tools, a cumbersome process that hinders rapid maintenance. To address this, we propose an improved multi-legged robot... Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example

[0028] Please see Figure 1-9This utility model provides a technical solution: a multi-legged robot, including a robot body 1, which includes a main body 101, a first mechanical leg 102, and a second mechanical leg 103. The first mechanical leg 102 is connected to the main body 101, and the second mechanical leg 103 is connected to the other end of the first mechanical leg 102. A mounting plate 2 is fixedly installed at the bottom of the second mechanical leg 103. The mounting plate 2 is used to install a first sliding rod 5. A buffer box 3 is provided below the mounting plate 2. A first spring 4 is provided inside the buffer box 3. The first spring 4 inside the buffer box 3 can play a certain cushioning role, so that when the robot makes some jumps... When the robot is moving, it can play a certain role in buffering and prevent the mechanical leg from being damaged by large impact for a long time. The buffer box 3 has a first circular groove 12 and a second circular groove 13 respectively. The bottom of the mounting plate 2 is fixedly installed with a first sliding rod 5. The first sliding rod 5 slides in the first circular groove 12. The bottom of the first sliding rod 5 is fixedly installed with a first retaining ring 6. The first retaining ring 6 slides in the second circular groove 13. When the robot moves, the second mechanical leg 103 presses down, which drives the mounting plate 2. The mounting plate 2 drives the first sliding rod 5. The first sliding rod 5 drives the first retaining ring 6. The first retaining ring 6 will then compress the first spring 4, causing it to deform.

[0029] Both sides of the buffer box 3 are fixedly equipped with sockets 7, which are used to connect with the plugs 8. The plugs 8 are inserted into the bottom of the sockets 7, and the bottom plate 9 is fixedly installed on the bottom of the plugs 8. The bottom plate 9 drives the plugs 8. The bottom of the bottom plate 9 is integrally formed with foot pads 10, which can effectively prevent mechanical legs from being worn. A fixing rod 15 is inserted into the front of the socket 7. The fixing rod 15 is used to fix the plugs 8 on the socket 7. A pull plate 11 is fixedly connected to the fixing rod 15, and an elastic locking mechanism is provided on the pull plate 11.

[0030] The first circular groove 12 is connected to the second circular groove 13. The first circular groove 12 is located above the second circular groove 13, and the diameter of the first circular groove 12 is smaller than that of the second circular groove 13.

[0031] The diameter of the first circular groove 12 is the same as the diameter of the first sliding rod 5. The first sliding rod 5 slides in the first circular groove 12. The diameter of the second circular groove 13 is the same as the diameter of the first retaining ring 6. The first retaining ring 6 slides in the second circular groove 13. One end of the first spring 4 is fixedly connected to the bottom wall of the inner cavity of the second circular groove 13, and the other end of the first spring 4 is fixedly connected to the bottom of the first retaining ring 6. The first sliding rod 5 drives the first retaining ring 6 to move down, and the first retaining ring 6 will squeeze the first spring 4.

[0032] A fixing groove 14 is provided on the front of the insertion post 8. During the replacement of the foot pad 10, the fixing rod 15 disengages from the fixing groove 14 on the front of the insertion post 8.

[0033] The buffer box 3 has a third circular groove 16 on its front side.

[0034] The elastic locking mechanism includes a second slide rod 18 fixedly installed on the pull plate 11. The pull plate 11 drives the second slide rod 18. A second retaining ring 19 is fixedly installed at one end of the second slide rod 18. The second slide rod 18 drives the second retaining ring 19, which slides within the third circular groove 16. A second spring 20 is sleeved on the outer wall of the second slide rod 18. One end of the second spring 20 is fixedly connected to the second retaining ring 19, and the other end is fixedly connected to the inner wall of the third circular groove 16. The second retaining ring 19 compresses the second spring 20, causing it to deform. A pull block 17 is fixedly installed on the front of the pull plate 11. Pulling the pull block 17 drives the pull plate 11.

[0035] In this embodiment, the robot body 1 is model MN989; its structural principle and usage method are existing technologies and will not be described in detail here.

[0036] Specifically, when the multi-legged robot is in use: when the robot is moving, the second mechanical leg 103 presses down, which drives the mounting plate 2. The mounting plate 2 drives the first sliding rod 5 to move down, and the first sliding rod 5 drives the first retaining ring 6 to move down. The first retaining ring 6 will then compress the first spring 4, causing it to deform. In this way, when the robot makes some jumping movements, it can play a certain buffering role and prevent the mechanical leg from being damaged by large impact forces for a long time.

[0037] When the foot pad 10 needs to be replaced after long-term use, first pull the pull block 17. The pull block 17 drives the pull plate 11, the pull plate 11 drives the second slide rod 18, the second slide rod 18 drives the second retaining ring 19, the second retaining ring 19 squeezes the second spring 20, causing it to deform. At the same time, the pull plate 11 drives the fixing rod 15, causing the fixing rod 15 to disengage from the fixing groove 14 on the front of the plug 8. Then pull the bottom plate 9, the bottom plate 9 drives the plug 8 to disengage from the socket 7, and the foot pad 10 can be removed.

[0038] Next, the new foot pad 10 is installed. Pinch the base plate 9, which drives the insert post 8 to insert into the socket 7. Then release the pull block 17, and the second spring 20 returns, which drives the pull plate 11. The pull plate 11 drives the fixing rod 15 to insert into the fixing groove 14, thus completing the installation of the new foot pad 10. This allows for convenient and quick replacement of the foot pad 10 at the bottom of the mechanical leg. Moreover, only the foot pad 10 needs to be replaced, reducing the cost of use and improving the speed of maintenance.
