AI Technical Summary
The slider and connecting rod structure of the existing bionic frog jumping robot are easily stuck during energy storage, resulting in difficulty in releasing the slider and the hind leg assembly is in an active state, affecting the stability of the jumping action.
A snap mechanism including a slider body, a guide member and a rotating member is designed. Through the coordination of the limit groove of the rotating member and the elastic buckle, the slider can stably escape from the guide member during energy storage and when released. Smoothly pull the connecting rod so that the hind leg assembly remains stationary before jumping.
The stable separation between the slider and the guide member is achieved, ensuring the stability of the energy storage process and the smoothness of the jumping action, and avoiding unnecessary movement caused by the difficulty of releasing the slider and the linkage activity.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sliding buckle structures, and more specifically to a buckle mechanism for a bionic frog. Background Art
[0002] In a bionic frog jumping robot, if the frog's hind leg assembly wants to open and jump, it needs to connect the slider moving along the lead screw through a connecting rod, and the tension spring connected to the slider is stretched and stored and then released to realize the jumping action. The existing structure is that the connecting rod always moves with the sliding of the slider, and the slider includes a detachable guide member, and the guide member is limited by a rotatable buckle on the slider, so that the guide member can drive the slider to move together. When the slider moves to a certain height, the buckle is pushed up by a block in a fixed position, so that the guide member and the slider are disengaged, and the slider is pulled back by the tension spring to drive the connecting rod to move so that the leg assembly opens and completes the jump. However, this result has the following problems: 1. When the slider rises with the lead screw, the tension of the tension spring on the slider gradually increases, and the buckle will also buckle the guide member more and more tightly, resulting in the block failing to successfully push up the buckle, causing the buckle to be stuck and the slider difficult to release. 2. The slider is always connected to the connecting rod, so the slider always drives the connecting rod to move when it is pulled, causing the rear leg assembly to be active when the slider is storing energy, resulting in unstable energy storage of the slider. Therefore, a technical solution is needed to solve the above problem. Utility Model Content
