Quick coupler auto-lock mechanism and method

A quick coupler (400) and a method of coupling and decoupling a quick coupler with a work tool (500) are disclosed. The quick coupler includes a frame (410), a cylinder (420), a primary blocking member (430), a secondary blocking member (440), a biasing member (450), and a controller. The coupling method includes initiating an automatic locking state (Figure 9B-9D), automatically locking the second tool pin (520) within the hook (412), entering the first tool pin (510) into the recess (411), and initiating a locking state (Figure 9E). The decoupling method includes initiating an auto-lock state, resting a work tool on a surface, initiating an unlock state (Figure 9A), and separating the quick coupler and the work tool. Advantageously, the quick coupler can automatically lock the second tool pin without actuating the cylinder. 公开了一种快速耦合器(400)以及将快速耦合器与作业工具(500)耦合和解耦方法。快速耦合器包括框架(410)、汽缸(420)、主阻挡构件(430)、辅阻挡构件(440)、偏压构件(450)和控制器。该耦合方法包括启动自动锁定状态(图9B-9D)、将第二工具销(520)自动锁定在钩(412)内、第一工具销(510)进入凹口(411)，以及启动锁定状态(图9E)。解耦方法
