Detailed implementation manners
[0021] In order to more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below with reference to the accompanying drawings and the description of the embodiments or the prior art. Obviously, the following description of the structures of the drawings is only some embodiments of the present invention. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts. It should be noted here that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation to the present invention.
[0022] Embodiment:
[0023] Such as Figure 1 , Figure 2 and Figure 3As shown, this embodiment provides a 6-legged multifunctional mechanical dog with arms, including a mechanical dog body 1 and front leg joints 2, middle leg joints 3 and hind leg joints 4 installed on both sides of the mechanical dog body 1 from front to back in sequence, the two front leg joints 2 are symmetrically arranged relative to the mechanical dog body 1, the two middle leg joints 3 are symmetrically arranged relative to the mechanical dog body 1, and the two hind leg joints 4 are also symmetrically arranged relative to the mechanical dog body 1 to ensure the overall stability and aesthetic standards of the appearance, the middle leg joints 3 are located on both sides of the middle part of the mechanical dog body 1, to ensure that the overall stability can still be ensured when the whole is supported only by the two middle leg joints 3 and the two hind leg joints 4, and in practice, the two middle leg joints 3 can be set in the middle front position of the mechanical dog body 1, so that the overall stability can be better maintained. The front leg joint 2 includes a front thigh 201, a front calf 202 and an electric clamp 203. The lower end of the front thigh 201 is rotatably connected with the upper end of the front calf 202 to ensure that the front calf 202 can rotate relative to the front thigh 201, so that the front leg joint 2 can achieve the purpose of bending walking. At the same time, in order to achieve the walking of the front leg joint 2, both sides of the front end of the mechanical dog body 1 are equipped with front thigh driving motors 205 for driving the front thigh 201 to rotate. The front thigh driving motor 205 can control the rotation of the front thigh 201, thereby ensuring that the front thigh 201 The front thigh drive motor 205 is provided with a front calf drive motor 206 on its motor shaft. The housing of the front calf drive motor 206 is fixedly connected to the upper end of the front thigh 201 to ensure the stability of the front calf drive motor 206. The motor shaft of the front calf drive motor 206 is transmission-connected to the upper end of the front calf 202. The rotation of the front calf 202 can be controlled by the drive of the front calf drive motor 206 to ensure the flexibility of the front calf 202. At the same time, the front thigh 201 and the front calf 202 are driven by different motors respectively. Through the cooperation of the two motors, it can be ensured that the front leg joint 2 can achieve the purpose of bending walking. On this basis, the front calf A gripper drive motor 204 is installed on one side of the lower end of the leg 202, and the motor shaft of the gripper drive motor 204 is connected to the electric gripper 203. When the foreleg joint 2 is used for walking, the gripper drive motor 204 can drive the electric gripper 203 to rotate to a retracted state, thereby not affecting the coordination of the foreleg joint 2 with the middle leg joint 3 and the hind leg joint 4 to achieve the six-leg walking action. When the foreleg joint 2 needs to clamp an object, it can only use the middle leg joint 3 and the hind leg joint 4 to walk in coordination with each other to perform four-leg walking, while the gripper drive motor 204 drives the electric gripper 203 to rotate forward, and then the electric gripper 203 is used to grab objects, thereby realizing the multifunctional application of the six-legged multifunctional mechanical dog.
[0024] By installing the front thigh drive motor 205 on the body 1 of the robotic dog, the installation of the two front leg joints 2 at the front end of the body 1 of the robotic dog is realized. Then, in combination with the two middle leg joints 3 and the two hind leg joints 4, the robotic dog can achieve six-legged walking and running, and the overall stability is better.
[0025] When the present invention drives the front leg joint 2 to walk, the front thigh drive motor 205 is used to control the rotation of the front thigh 201, and the front calf drive motor 206 is used to control the rotation of the front calf 202. Furthermore, through the cooperation of the front thigh drive motor 205 and the front calf drive motor 206, the flexible adjustment between the front thigh 201 and the front calf 202 can be realized, and then the front leg joint 2 can achieve the walking operation.
[0026] A gripper drive motor 204 is installed on one side of the lower end of the front calf 202. The motor shaft of the gripper drive motor 204 is connected to the electric gripper 203. When the front leg joint 2 walks, the gripper drive motor 204 can control the electric gripper 203 to rotate upward, thus not affecting the walking of the front leg joint 2. When it is necessary to use the electric gripper 203 to pick up an item, the gripper drive motor 204 can control the electric gripper 203 to rotate forward, so that the robotic dog walks using the two middle leg joints 3 and the two hind leg joints 4, and the front leg joint 2 can pick up the item under the control of the electric gripper 203, realizing the multi-functional operation of the robotic dog and completing additional work.
[0027] As a preferred implementation in this embodiment, it should be further noted that the motor shaft of the front calf drive motor 206 is connected with a first synchronous pulley 207. The first synchronous pulley 207 and the front calf 202 are on the same side of the front thigh 201, while the front calf drive motor 206 is on the other side of the front thigh 201, making the overall structure symmetrically arranged, the weight distribution more reasonable, and ensuring the stability of the structure. A second synchronous pulley 208 is installed on one side of the upper end of the front calf 202, so that the first synchronous pulley 207 and the second synchronous pulley 208 are on the same side. The first synchronous pulley 207 and the second synchronous pulley 208 are connected by a synchronous belt 209. Furthermore, it is convenient to control the rotation of the first synchronous pulley 207 by the front calf drive motor 206.
