DETAILED DESCRIPTION
[0025] In order to facilitate the transportation of the quadruped robot, provide protection for the robot from falling, achieve reliable assembly of the joint motor group, and provide product scalability, this application proposes a multifunctional and modular framework.
[0026] Combine Figures 1 to 4The quadruped robot equipped with a multifunctional frame is composed of a robot trunk 1, several multifunctional frames 2, and robot legs 3; the multifunctional frames 2 can be installed or removed from the robot trunk 1 according to needs; the multifunctional frame 2 is composed of a frame main structure 2.1, a frame handle 2.2, a frame outer extension assembly surface 2.3, a joint motor double-end support shaft 2.4, and a frame ground contact part 2.5.
[0027] The multifunctional frame 2 is fixed to the robot trunk 1 by bolts (but not limited to bolts), specifically connected to the trunk frame 1.1 of the robot trunk 1; the frame main structure 2.1 in the multifunctional frame 2 is connected to other structures by welding, bolts or gluing (but not limited to these forms); the frame handle 2.2 can be used as a handle for manual transportation, and can also be used as a lifting point for hoisting, airdrop, etc.; the outer extension assembly surface 2.3 of the frame is provided with threaded holes or bayonet structures (but not limited to these forms), and specific products can be installed on the assembly surface according to user needs; the double-end support shaft 2.4 of the joint motor is hinged to the joint motor group 1.2 through bearings or other structures, such as Figure 3 As shown, a second support point is realized in addition to the mounting surface of the joint motor group 1.2 body, thereby achieving the effect of double-end fixed support of the joint motor group 1.2 without affecting the rotation and torque output of the motor itself; the frame contact part 2.5 is used as an overall support member when the robot lies down, such as Figure 4 shown.
[0028] When the quadruped robot needs to be transported or hoisted, it can be achieved through the frame handle 2.2, and a targeted hoisting and fixing structure can be designed according to different needs.
[0029] When it is necessary to install specific external components on the quadruped robot, they can be installed on the extended assembly surface 2.3 outside the frame according to the needs, and targeted or universal assembly structures can be designed according to the differences in needs.
[0030] When the robot needs to lie down, the frame contact part 2.5 is used as an integral support member, such as Figure 4 As shown; in addition, the bottom of the frame contacting part 2.5 is lower than the robot torso 1, and the top of the multifunctional frame 2 is higher than the robot torso 1, which can effectively help the robot torso 1 and the internal structure to relieve the impact when falling or falling.
[0031] The multifunctional frame 2 can realize one or more functions of a handle, a support, an expansion piece installation, and a joint motor assembly installation.
[0032] Preferably, there are four multifunctional frames 2 , which are respectively arranged at the four corners of the robot trunk 1 , or the four multifunctional frames 2 are connected and merged into one frame.
