A few robot legs that do not use a wheel structure can only achieve one degree of freedom of movement, that is, movement in the forward direction. This makes the walking movements of robot legs stiff and mechanical. The few robot legs that can achieve multi-degree-of-freedom movement also have a very complex structure, and the cost and selling price are very high.

[0003] A search revealed a Chinese patent publication number: CN213159375U, which provides a robot leg block, including a foot plate, a ball joint connecting rod, a swing rod assembly, a first gear, and a swing lower support; the upper end of the ball joint connecting rod is connected to the ball joint of the first gear and is eccentrically positioned; the lower end of the ball joint connecting rod is connected to the ball joint of the foot plate; the swing rod assembly includes a first swing rod and a second swing rod, with the first swing rod, the ball joint connecting rod, and the second swing rod arranged sequentially.

[0004] Although the aforementioned patent can achieve multi-degree-of-freedom motion, the aforementioned device still has the following problems: during the use of the device, since the connection structure of the device is directly exposed to the external environment, objects in the external environment are prone to colliding with the connection structure, causing damage to the connection structure and resulting in failure of the connection between the robot's legs and footplates. In order to address the above situation, technological innovation is carried out on the basis of the existing device. Utility Model Content

[0022] Please see Figure 1-4 This utility model provides a technical solution: a robot leg block structure, including a foot plate 1, with a robot leg 2 mounted on the top of the foot plate 1. The robot leg 2 is an existing structure and will not be described in detail here. The robot leg 2 moves by driving the foot plate 1, enabling the robot to walk. A moving groove 3 is provided inside the foot plate 1, and a mounting plate 11 is slidably connected inside the moving groove 3. A base 4 is provided on the top of the mounting plate 11, and the surface of the base 4 is slidably connected to the inside of the moving groove 3. Two symmetrical support plates 5 are fixedly connected to the top of the base 4. The connecting piece of the robot leg 2 is located between the two support plates 5. A positioning groove 8 is provided inside the support plate 5, and a positioning groove 8 is also provided on the connecting piece of the robot leg 2. The inner... The device has a sliding groove 9, and a movable frame 6 extending to the outside of the sliding groove 9 is slidably connected inside the sliding groove 9. The movable frame 6 has an L-shaped cross-section, and a positioning shaft 7 is fixedly connected to one side of the movable frame 6. The surface of the positioning shaft 7 is slidably connected to the inside of the positioning groove 8. The positioning shaft 7 passes through the inside of the connector on the support plate 5 and the robot leg 2, so that the foot plate 1 and the robot leg 2 can be connected. At the same time, the movement of the positioning shaft 7 makes the connection between the foot plate 1 and the robot leg 2 more convenient, and makes the foot plate 1 and the robot leg 2 easier to install and disassemble, and makes it easier for users to use the device. The foot plate 1 has a power groove 12 that communicates with the inside of the sliding groove 3. The inside of the power groove 12 is equipped with a storage support device.

[0023] A tension spring 10 is fixedly connected inside the slide 9. The end of the tension spring 10 near the moving frame 6 is fixedly connected to the surface of the moving frame 6. The movement of the moving frame 6 can stretch and reset the tension spring 10. The tension spring 10 can make the positioning shaft 7 more stably connect the foot plate 1 and the robot leg 2.

[0024] Mounting block 18 is fixedly connected to the top of mounting plate 11, and mounting groove 19 is provided at the bottom of base 4. The surface of mounting block 18 and the interior of mounting groove 19 are slidably connected. The cross-section of mounting block 18 and mounting groove 19 are both trapezoidal. Mounting block 18 is fixedly mounted on base 4 by bolts. The bolt fixing of mounting block 18 makes the installation and disassembly of base 4 more convenient and makes the later maintenance of base 4 and support plate 5 smoother.

[0025] The storage support device includes a support frame 13, the surface of which is slidably connected to the inside of the power groove 12. The support frame 13 can support and fix the mounting plate 11, so that the foot plate 1 can be more stably connected and installed with the robot leg 2. The base 4 can be stored by sliding into the moving groove 3, which reduces the direct exposure of the base 4 to the external environment. This reduces the risk of objects in the external environment colliding with the support plate 5 and causing damage to the support plate 5, which could lead to connection failure between the robot leg 2 and the foot plate 1. This allows the foot plate 1 and the robot leg 2 to be connected more smoothly. At the same time, when the base 4 is stored, the support frame 13 can block the support plate 5, making the storage of the base 4 more stable. A first spring 14 is fixedly connected to one side of the support frame 13. The end of the first spring 14 away from the support frame 13 is fixedly connected to the inner wall of the power groove 12. The movement of the support frame 13 can compress and reset the first spring 14.

[0026] The movable groove 3 has a limiting groove 15 inside. The mounting plate 11 is fixedly connected to the limiting slider 17 on the side near the limiting groove 15. The surface of the limiting slider 17 is slidably connected to the inside of the limiting groove 15. The bottom of the limiting slider 17 is fixedly connected to a second spring 16. The bottom end of the second spring 16 is fixedly connected to the inner wall of the limiting groove 15, so that the movement of the limiting slider 17 can compress and reset the second spring 16.

[0027] Working principle: For this type of robot leg block structure, the worker first pulls the support fixing frame 13 to release the obstruction of the support fixing frame 13 on the support plate 5. The mounting plate 11 is reset under the action of the second spring 16, and the base 4 slides out of the interior of the moving groove 3. The support fixing frame 13 is reset to block the mounting plate 11. The support fixing frame 13 can support and fix the mounting plate 11, so that the foot plate 1 can be connected and installed more stably with the robot leg body 2.

[0028] After the worker moves the frame 6, the robot leg 2 slides between the two support plates 5. The positioning shaft 7 passes through the connector on the support plate 5 and the robot leg 2, which can connect the foot plate 1 and the robot leg 2. At the same time, the movement of the positioning shaft 7 makes the connection between the foot plate 1 and the robot leg 2 more convenient, and makes the foot plate 1 and the robot leg 2 easier to install and disassemble, and makes it easier for users to use the device.

[0029] When the device is not in use, the base 4 can be slid into the moving slot 3 to store the base 4. This reduces the direct exposure of the base 4 to the external environment, preventing objects in the external environment from colliding with the support plate 5 and causing damage to the support plate 5, which could lead to a failure in the connection between the robot's legs 2 and foot plate 1.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
