Description

Technical Field

[0001] This utility model relates to the field of robotics technology, specifically to a modular servo motor quick-connect structure suitable for small joints. Background Technology

[0002] In the field of robotics, small joints are components that enable flexible joint movement and precise actions. Small joints are usually equipped with servo motor connection structures on their outer sides, and these servo motor connection structures need to be adapted to the small joints.

[0003] Because the external space of small joints is extremely limited, traditional servo motor connection structures are too large and will interfere with other components during the embedding process, thus failing to be successfully embedded outside the small joint. In addition, traditional servo motor connection structures have a certain weight, which increases the burden on small joints and affects their movement flexibility. Furthermore, the connection structure has poor elasticity, and the external connection structure can easily restrict the flexible movement of small joints in multiple directions and angles. Therefore, this patent proposes a modular servo motor quick connection structure suitable for small joints to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a modular servo quick-connect structure suitable for small joints, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular servo quick-connect structure suitable for small joints, including multiple adapters and multiple small joints. The adapters are embedded on the outside of the small joints. The adapters are provided with an adapter positioning component, and the small joints are provided with a joint positioning component. The adapter positioning component is adapted to the joint positioning component. The inner contour of the adapter matches the outer contour of the small joint, so as to avoid interference with other components when the adapter is embedded on the outside of the small joint.

[0006] Preferably, the adapter is made of high-strength plastic to avoid increasing the overall weight of the small joint and affecting its mobility.

[0007] Preferably, the plurality of adapters include upper arm adapter connectors, forearm adapter connectors, torso adapter connectors, thigh adapter connectors, and lower leg adapter connectors. Each adapter is assembled from a first splicing component and a second splicing component. The plurality of small joints include upper arm joints, forearm joints, torso joints, thigh joints, and lower leg joints. Each small joint is assembled from a first mounting component and a second mounting component.

[0008] Preferably, the upper arm adapter connector is embedded on the outside of the upper arm joint, the forearm adapter connector is embedded on the outside of the forearm joint, the torso adapter connector is embedded on the outside of the torso joint, the thigh adapter connector is embedded on the outside of the thigh joint, and the lower leg adapter connector is embedded on the outside of the lower leg joint.

[0009] Preferably, the adapter positioning component includes a positioning block, which is fixed to the inner side of the adapter, and the joint positioning component includes a positioning hole, which is opened on the outer side of the small joint, and the positioning block is adapted to the positioning hole.

[0010] Preferably, the adapter positioning component is disposed on the first splicing component and the second splicing component, and the joint positioning component is disposed on the first mounting component and the second mounting component.

[0011] Compared with the prior art, the beneficial effects of this utility model are: By matching the inner contour of the adapter with the outer contour of the small joint, the overall volume of the adapter is kept to a minimum. It can be smoothly embedded in the outside of the small joint without interfering with other components, making full use of the limited space. To avoid increasing the burden on the small joint and affecting its movement flexibility, the adapter is made of lightweight high-strength plastic. High-strength plastic not only has a low density, but also meets the strength and rigidity requirements of the connection structure, further reducing the weight of the connection structure. In addition, the lightweight high-strength plastic of the adapter has a certain degree of elasticity, allowing the servo to be finely adjusted within a certain range to adapt to the movement needs of the joint. This facilitates the small joint to achieve flexible movement in multiple directions and angles, and the adapter does not limit its range of motion. Attached Figure Description

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.

[0015] In the field of robotics, small joints 2 are components that enable flexible joint movement and precise actions. Small joints 2 are usually equipped with servo motor connection structures on their outer sides, and these servo motor connection structures need to be adapted to the small joints 2.

[0016] like Figures 1-3 As shown, this utility model provides a technical solution: a modular servo quick-connect structure suitable for small joints, including multiple adapters 1 and multiple small joints 2. The adapters 1 are embedded on the outside of the small joints 2. An adapter positioning component 3 is provided on the adapter 1, and a joint positioning component 4 is provided on the small joint 2. The adapter positioning component 3 and the joint positioning component 4 are adapted to each other. The inner contour of the adapter 1 matches the outer contour of the small joint 2, avoiding interference with other components when the adapter 1 is embedded on the outside of the small joint 2. The adapter 1 is made of high-strength plastic material to avoid increasing the overall weight of the small joint 2 and affecting its movement flexibility.

[0017] It is important to note that by matching the inner contour of adapter 1 with the outer contour of small joint 2, the overall volume of adapter 1 is kept to a minimum. It can be smoothly embedded in the outside of small joint 2 without interfering with other components, making full use of the limited space. To avoid increasing the burden on small joint 2 and affecting its movement flexibility, adapter 1 is made of lightweight high-strength plastic. High-strength plastic not only has a low density, but also meets the strength and rigidity requirements of the connection structure, further reducing the weight of the connection structure. In addition, the lightweight high-strength plastic of adapter 1 has a certain degree of elasticity, allowing the servo to be finely adjusted within a certain range to adapt to the movement needs of the joint, which facilitates the flexible movement of small joint 2 in multiple directions and angles. Adapter 1 will not limit its range of motion.

Each adapter 1 is assembled from a first splicing component and a second splicing component. Multiple small joints 2 include an upper arm joint 201, a forearm joint 202, a torso joint 203, a thigh joint 204, and a lower leg joint 205. Each small joint 2 is assembled from a first mounting component and a second mounting component. The upper arm adapter connector 101 is embedded on the outside of the upper arm joint 201, the forearm adapter connector 102 is embedded on the outside of the forearm joint 202, the torso adapter connector 103 is embedded on the outside of the torso joint 203, the thigh adapter connector 104 is embedded on the outside of the thigh joint 204, and the lower leg adapter connector 105 is embedded on the outside of the lower leg joint 205. The adapter positioning component 3 includes a positioning block 301, which is fixed to the inner side of the adapter 1. The joint positioning component 4 includes a positioning hole 401, which is opened on the outer side of the small joint 2. The positioning block 301 is adapted to the positioning hole 401. The adapter positioning component 3 is disposed on the first splicing component and the second splicing component, and the joint positioning component 4 is disposed on the first mounting component and the second mounting component.

[0019] It should be noted that the adapter 1 and the small joint 2 are positioned by corresponding positioning blocks 301 and positioning holes 401, which makes it easy to embed the adapter 1 into the outside of the small joint 2 and facilitates quick installation later.
