Description

Technical Field

[0001] This utility model relates to the field of robotics technology, specifically to a bionic robotic dog. Background Technology

[0002] With the rapid development of technology, bionic robot dogs, as a product of the integration of artificial intelligence and robotics, have shown great application potential in multiple fields. They are gradually being applied in the military, rescue, industrial, and service sectors.

[0003] Currently, existing bionic robot dogs typically move by using motors to drive their legs during movement. However, when the robot dog is under load, the joints of the mechanical legs bend and fall to the ground, increasing the load on the joints. As a result, the robot dog may fall over during weight-bearing movements because the joints cannot withstand the corresponding load. In order to improve the stability of its weight-bearing movements, a new type of bionic robot dog is proposed. Utility Model Content

[0004] The main objective of this invention is to provide a bionic robotic dog that can solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention proposes a bionic robotic dog, comprising a robotic dog body with four sets of mechanical legs. Each mechanical leg is composed of a support arm 1 and a support arm 2 hinged together. A wheel-type support foot is provided at the end of the support arm 2 away from the support arm 1. A reinforcing support mechanism is provided on each mechanical leg, the reinforcing support mechanism comprising:

[0006] An electric telescopic rod, which is hinged to the outer wall of a support arm;

[0007] A protective connection assembly is provided on the output end of the electric telescopic rod. The protective connection assembly is connected to the connecting rod, and the connecting rod is hinged to the support arm.

[0008] The buffer assembly is installed on the protective connection assembly. By strengthening the support mechanism, the support strength of support arm one and support arm two can be enhanced, preventing support arm two from bending excessively during the weight-bearing movement of the robot dog body, thereby reducing the possibility of the robot dog body falling over.

[0009] Preferably, the protective connection assembly includes a first disc, a second disc, a rod, a limiting block, and a connecting spring. The rod is fixed to the second disc and passes through the first disc, and is slidably connected to the first disc.

[0010] Preferably, the first disc is fixed to the telescopic end of the electric telescopic rod, and the second disc is fixed to the end of the connecting rod away from the second support arm.

[0011] Preferably, the two ends of the connecting spring are fixed on disk one and disk two respectively, and the connecting spring is sleeved on the outside of the round rod.

[0012] Preferably, the buffer assembly includes a cylinder, an air chamber, a piston ring, a flow channel, and a linkage rod. The air chamber is filled with inert gas, the piston ring is piston-connected to the air chamber, and the linkage rod passes through the cylinder and is slidably connected to the cylinder. When the linkage rod drives the piston ring to move in the air chamber, the gas moves through the flow channel, generating a damping force in the process, causing the second disc and the first disc to move closer to each other. When the connecting spring is compressed, it plays a buffering and protective role.

[0013] Preferably, the cylinder is fixedly connected to the side of the first disc near the second disc, one end of the linkage rod is fixed to the piston ring, and the other end of the linkage rod is fixed to the second disc.

[0014] Preferably, the two ends of the flow channel are not on the same central axis.

[0015] This invention provides a bionic robotic dog. It has the following beneficial effects:

[0016] (1) By strengthening the use of the support mechanism, the electric telescopic rod is hinged to the support arm one and linked to the support arm two through the protective connection component and the connecting rod to form a triangular support structure. When the robot dog is under load, the electric telescopic rod can adjust the extension length and distribute the load pressure of the support arm two to the support arm one through the connecting rod. With the use of the protective connection component, the support arm two is prevented from bending excessively, which effectively reduces the risk of falling over due to insufficient joint load.

[0017] (2) The bionic robot dog uses a buffer component, in which the air chamber and piston ring form a damping buffer structure. When the joint is impacted, the linkage rod drives the piston ring to compress the inert gas, and the damping force is generated through the flow groove to absorb the vibration energy. At the same time, the connecting spring is compressed synchronously. The dual buffer mechanism can reduce the impact force at the moment of landing. This design enables the robot dog to effectively buffer the ground reaction force when walking with a load, keep the body stable, and maintain gait stability through buffer adjustment even on rugged terrain, thus improving the reliability of movement in complex environments.

[0025] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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] Please see Figures 1-4 This utility model proposes a bionic robot dog, including a robot dog body 1. The robot dog body 1 is provided with four sets of mechanical dog legs. The mechanical dog legs are composed of a first support arm 2 and a second support arm 3 hinged together. The first support arm 2 can be driven by an existing joint motor. The second support arm 3 is provided with a wheeled support foot 4 at the end away from the first support arm 2. The roller of the wheeled support foot 4 can be driven by a motor. Through the combined use of the first support arm 2, the second support arm 3 and the wheeled support foot 4, the robot dog can walk and move by rollers at the same time, adapting to different regions. The mechanical dog legs are provided with a reinforcing support mechanism 5.

[0028] In this embodiment of the utility model, in order to strengthen the support of the second support arm 3, the strengthening support mechanism 5 specifically includes an electric telescopic rod 51, a protective connecting component 52, and a buffer component 53. The electric telescopic rod 51 is hinged to the outer wall of the first support arm 2. The protective connecting component 52 is disposed on the output end of the electric telescopic rod 51 and is connected to the connecting rod 54. The connecting rod 54 is hinged to the second support arm 3. The buffer component 53 is disposed on the protective connecting component 52. The first support arm 2 is hinged by the electric telescopic rod 51, and the second support arm 3 is linked by the protective connecting component 52 and the connecting rod 54 to form a triangular support structure. When the robot dog is under load, the extension length of the electric telescopic rod 51 can be adjusted. The load pressure of the second support arm 3 is distributed to the first support arm 2 through the connecting rod 54. With the use of the protective connecting component 52, the second support arm 3 is prevented from bending excessively, effectively reducing the risk of falling due to insufficient joint load bearing.

[0029] Furthermore, the protective connection assembly 52 includes a first disc 521, a second disc 522, a round rod 523, a limiting block 524, and a connecting spring 525. The round rod 523 is fixed to the second disc 522, passes through the first disc 521, and is slidably connected to the first disc 521. The first disc 521 is fixed to the telescopic end of the electric telescopic rod 51. The second disc 522 is fixed to the end of the connecting rod 54 away from the second support arm 3. The two ends of the connecting spring 525 are respectively fixed to the first disc 521 and the second disc 522, and the connecting spring 525 is sleeved on the outside of the round rod 523. During the movement of the second support arm 3, when the second support arm 3 contacts the ground, under the action of the impact force, the second disc 522 drives the round rod 523 to move, thereby compressing the connecting spring 525 and reducing the impact force at the moment of landing.

[0030] Furthermore, the buffer assembly 53 includes a cylinder 531, an air chamber 532, a piston ring 533, a flow channel 534, and a linkage rod 535. The air chamber 532 is filled with inert gas. The piston ring 533 is piston-connected to the air chamber 532. The linkage rod 535 passes through the cylinder 531 and is slidably connected to the cylinder 531. The cylinder 531 is fixedly connected to the side of the first disc 521 near the second disc 522. One end of the linkage rod 535 is fixed to the piston ring 533, and the other end of the linkage rod 535 is fixed to the second disc 522. The two ends of the flow channel 534 are not on the same central axis. During the impact of the second support arm 3 contacting the ground, the second disc 522 moves closer to the first disc 521. When the linkage rod 535 drives the piston ring 533 to move in the air chamber 532, the gas moves through the flow groove 534, generating damping force to absorb the vibration energy. With the synchronous compression of the connecting spring 525, the double buffering mechanism can reduce the impact force at the moment of landing. This design enables the robot dog to effectively buffer the ground reaction force when walking with a load, keeping the body stable. Even on rough terrain, it can maintain gait stability through buffering adjustment, improving the reliability of movement in complex environments.

[0031] It should be noted that the above electrical components are all existing technology products. Those skilled in the art should select, install and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or components known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here.

[0032] In use, the motor drives the support arm 12 to move, enabling the robot dog body 1 to walk. Simultaneously, the support arm 12 is hinged to the electric telescopic rod 51 and linked to the support arm 23 via the protective connecting component 52 and the connecting rod 54, forming a triangular support structure. When the robot dog is under load, the electric telescopic rod 51 can adjust its extension length, and the load pressure of the support arm 23 is distributed to the support arm 12 via the connecting rod 54. When the support arm 23 contacts the ground, under the impact force, the disc 222 drives the rod 523 to move, compressing the connecting spring 525. When the connecting rod 535 drives the piston ring 533 to move in the air chamber 532, the gas moves through the flow groove 534, generating damping force to absorb vibration energy. Combined with the synchronous compression of the connecting spring 525, the impact force at the moment of landing can be reduced, preventing the support arm 23 from bending excessively.

All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
